Leap Motion

Leap Motion Many of us are aware of the Leap Motion with is a small, $70 gesture control system that simply plugs into any computer and, apparently, just works. The most important thing is that, if you're familiar with the touch modality the interface is entirely intuitive (Christopher, 2012). It's touch, except it happens in the space in front of the screen, so we don't have to cover our window into our tech with all those unsightly smudges. This new technology unlike a touchscreen interface, we can just move our fingers with touching the scream and the pens inside just draw exactly what you leaps are.It's the difference between attempting to conduct a symphony with a wand and attempting to conduct the same symphony by sketching out what the orchestra should do next via chalk on a blackboard. Further more, Leap operates in three dimensions rather than two. Just imagine to â€Å"push to scroll,† rotating your flattened hand to control the orientation of an object with a full s ix degrees of freedom, or using both hands at once to control either end of a bezier surface you're casually sculpting as part of an object you'll be sending to your 3D printer (Christopher, 2012). I think this new technology is very useful to the stores like apple store.Since this kind of stores is a big market sale smart phone, touch scream pads and high quality laptops, it would be better production and financial operating with this higher and attractive technology. For example, as we all know that apple store is very popular in the world and people are just curious about what the new technology is will be come up every season with every new product. With the leap motion, people will be more convenient to do their work. So this will exactly improve the sale rations of the store. Expect the benefits it can make to the store, the leap motion will also be very useful to some companies’ technology production.For instance, for industry technology workers, they do not have to st and the whole day with the scream. They can just sit or walk wherever they want to do the work. This will be very convenient and flexible. So, the leap motion does bring us the value to our lives and it also promotes the technology development. Reference CHRISTOPHER MIMS. (2006, June 26).

Public Health Nursing Acts in Emergency Disasteres

he assignment for this paper asks about a disaster that could happen in my community. A disaster is any natural or human-made incident that causes disruption, and or devastation requiring external assistance (Stanhope & Lancaster, 2012, p.508). The purpose of the paper is to provide information how the professional nurse react in the community when a disaster take place.The disaster selected for the paper is a chemical plant fire explosions. I reside in an area that is reported to have quite a few chemical plants. In terms of human-made disaster prevention, the nurse should be aware of high-risk targets and current vulnerabilities and what can be done to eliminate or mitigate the vulnerability (Stanhope & Lancaster, 2012, p.512). Preventing, preparing for, responding to, and recovering from disasters and emergencies are the nurse roles for emergency disasters. Clinical judgment and decision-making skills Public health nurses’ skills are necessary to provide temporary housing, with basic health needs such as water and food resources, for people who must evacuate their homes and provides a safe place to eat, sleep.Age specifics are taken into consideration because of vulnerability and care need for the older adult population and children. Developing and testing systems for childcare and elder-care during public health emergencies could reduce the burden of competing responsibilities for nurses (O'Boyle, Robertson, & Secor-Turner, 2006). Children require special protection, especially nursing babies, infants and under-fives (ODPEM, 1989). Several nurses skilled to practice safely and competent are necessary for patient care in the event of a disaster in the community. The nurses must have knowledge of the environmental factors and the risk they put to themselves and other during the disaster.The public health nurse’s knowledge of the geographical locations of medical facilities and clinic to transport patients seriously injured needing care are impor tant to all persons involve in the disaster. Nurses need awareness of the surrounding medical facilities and services provided in their area, including alternate care sites and medical shelters (Stanhope & Lancaster, 2012). The public nurses are educated, trained and  skilled to respond quickly to aid in the disaster. Nurses have unique skills for all aspects of disaster to include assessment, priority setting, collaboration, and addressing of both preventive and acute care needs (Stanhope & Lancaster, 2012, p.511).The nurses provide education and emotional support to the community. It is the role of the public health nurse to communicate with all healthcare professionals such as physician, other nurses, emergency medical team, the emergency coordinator, and fire department personnel actively participating in the emergency disaster. Communication with health care participants will assist them in rapidly establishing priorities and necessary actions during the emergency disaster. C ommunication and collaboration among other health care professionals is critical for delivering safe effective patient care all areas of care.The nurses prepared at the Baccalaureate level must have knowledge of laws and ethics when making clinical judgments, and decision making. Nurses incorporate critical thinking, research and evidence base practice, informatics, cultural sensitivity and awareness in their practice when communicating information to other health care professional. Nurses prepared at the Baccalaureate level are educated to use respectful communication and collaboration to aid in care coordination, delegation, and conflict resolution in any situation when caring for patients and individual in the community.Developing partnerships between public and private health-care, emergency management, and law enforcement entities, while using current technology to promote timely disease identification and reporting, can improve the daily capacity of a community to respond to i llness and disease regardless of magnitude (CDC, 2013). Nursing StrategiesThere are strategies nurses can use in emergency disaster before it takes place. Work with the community providing education and teaching to identify hazards that could affect their local area. Use communication techniques holding public meetings and events for the community geared towards improving the public's understanding of a disaster and how to address disasters that may arise. The health and safety of the community following a disaster of any kind, therefore, depends on the ability of its residents to be â€Å"disaster ready.† (Adams, L., Canclini., S., 2008).Provide clear in-depth information about the chemicals hazards and the importance of  an organized response to the emergency of a chemical plant explosion. Encourage colleagues, by increasing awareness that disaster do happen in our communities. provide knowledgeable information about disasters. Set up programs with communities and facilit ies practicing drills and communication techniques. Drills enhance confidence in systems, individuals, procedures, and equipment (O'Boyle, Robertson, & Secor-Turner, 2006). Nursing leadership for prevention, preparedness and recovery is critical to ensure a multi-disciplinary, coordinated and evidence-based response for chemical plant disaster.Although public health nurses can function in many capacities, they are most likely to be deployed to the â€Å"operations section† because they bring leadership capacity, broad understanding of community systems, nursing knowledge, skills, and abilities (ASTDN 2007). During a public health emergency, occupational health nurses can be instrumentals in facilitating schedules and assignments that limit worker exposure to physically and psychologically over-whelming events (O'Boyle, Robertson, & Secor-Turner, 2006). Minimize errors owing to the absence of communication amongst health professionals.Accurate communication can reduce accident s and fatalities, stress and emotional conflict between health care professionals and the community population. To summarize this paper in short. Public health nurses’ roles are broad. The focus for nurses in the communities is to prevent diseases, provide teaching and education. The public health nurse’s experience and skills in the event of an emergency disaster promotes a positive outcome.

Research - Essay Example Their functions include planning and proactively monitoring and forecasting the changing requirements of the individual, coordinating his\her information regarding the care across all parts of the social and health care system, coordinating the care delivered to a patient group, facilitating communications between the hierarchies and care providers, overseeing the follow up of consultations and ensuring the linkage to other services, eliminating intervention and task duplication and ensuring implementation of the plans and their follow up (Mullahy, 1998). In summary, their functions can be generalized into four basics: A case manager should be possessing competencies in clinical training and having background knowledge of the job, communication and negotiation skills are imperative in such a job. Case managers need to be able to satisfactorily educate the patients and care providers. Possession of dexterity and in-depth knowledge of the ethics plus a strong character can help a case manager to voice dissidence when it is unavoidable. The case manager must be a strong problem-solver so that he can quickly and aptly solve technical, organizational and relational problems which might arise and so that he can avoid any variances to the plan all the way in its anticipated duration (Steinberg, 1996). Other competencies that a case manager shows are an aptitude for working in a team and a propensity for meeting hosting. Significant decision-making and leadership qualities are central to this role. A case manager has to be able to assert her belief in the case and communicate effectively to get others to follow the guidelines of the case management and adhere to them. Investigative skills play an important role in the case manager’s profile as they help him in overseeing, evaluating and correcting the implementation of the clinical

Humanities through the arts - Architecture Essay

Humanities through the arts - Architecture - Essay Example JÃ ¸rn Oberg Utzon created the Sydney Opera House which is one of most recognizable buildings in the world. These men made architecture an art form. Gustave Eiffel’s most recognizable work is the Eiffel Tower. Eiffel created a skyscraper for the first time that did not religious meaning or a military purpose (Dupre 2001:16-17). The intricate patterns of iron work that make up the Eiffel Tower are constructed to hold up from the wind. The pattern is abstract with no significance except to be wind proof. This immense tower is dated 1889 (Dupre 2001:16). The measurement of the height is 968 ft, or 300 m. (Dupre 2001:16). This structure was at the time the tallest in the world. Eiffel created a true masterpiece. The Johnson Wax Administration Building and Research Tower was created for the Johnson and Son Corporation by Frank Lloyd Wright. Part of the building was finished in 1939, but construction continued until 1955 (Lipman 2003:111). This building only cost $750,000, which gave Wright a commission of $50,000 (Lipman 2003:142). The new building had ascetic curves along with practical spaces. All of the new amenities like air conditioning, elevators, and other conveniences were created for this wax company. The work space was directly above the rest rooms, break rooms, and lockers connected by a spiral stair (Lipman 2003:183). This building was modern architecture at its best. JÃ ¸rn Oberg Utzon designed the Sydney Opera House. This achievement in surreal architecture has given Utzon a placed on the world monument list. The wooden ceiling is suspended from the roof (Giedion 1967:680). Utzon used new surreal concepts and made them a reality. This created a building suitable for opera. The shells that are used on the Sydney Opera House allowed Utzon to come up with a unique structure. Although many of the spaces in the Sydney House are not functional, the building has been considered a masterpiece. These three structures are all famous. The Johnson Wax

Religion and Theology Research Paper Example | Topics and Well Written Essays - 2000 words

Religion and Theology - Research Paper Example Therefore, this essay has the intention of discussing the existing beliefs of Christianity and those of Buddhism and they differ. Additionally, the paper will attempt to determine the inherent factors that influence afterlife in both religions such as soul is to Christianity and the mind to Buddhism. Alternatively, it is essential to note that while Christians believe in the existence of one God who defines matters of afterlife; Buddhists do not harbor such beliefs. However, the same Buddhist believes that the power of humanity lies in the purity of their minds whereby enlightenment is attained. There are various differences between Christianity and Buddhism on the context of their beliefs in the soul and afterlife. However, it is imperative to discuss the individual beliefs of Christianity and Buddhism in respect to how the soul relates with the existence of a person after he/she is dead. The basic Christian beliefs entail the belief that only one God exists (Bloom, 2012). This is b acked by the writings of the bible from the books of John, Corinthians, and Galatians among others. Similarly, most Christians believe God is in form on a Trinity. In other words, there is God the Father, the Son and God the Holy Spirit or Holy Grail. On the same note, a deep belief in Christianity maintains that God has the omnipotent power or is extremely powerful and hence is control of the entire universe. This is supported by the verse in the book of Psalm 115:3 among other biblical books. For the record, Christianity makes the allusion their God is the all powerful God. Furthermore, God is present everywhere or has omnipresence autonomy according basic Christian beliefs. There is also the element of sovereignty in the belief of Christians suggesting an element of a Supreme Being who is in control (Masih, 2000). Apart from the aforementioned elements of God, Christians also have an inherent belief in the existence of an afterlife. In the same aspect, Christians have a deep beli ef that a place called exists where sinners who have not repented are banished. Other basic beliefs of Christianity believe that God is true, God is love and God is the overall creator of all that lives among others. On the other hand, there are also basic Buddhism beliefs. For example, Buddhism follows the path of other beliefs in the context that it has its divisions. This suggests that it also shares the conventional set of the significant beliefs. On that aspect, one of the fundamental beliefs inherent with Buddhism is called reincarnation (Moreman, 2010). This entails the concept that there is rebirth of people after their death. In other words, the religion maintains that people go through phases of birth, living and rebirth. On that note, there are religious differences between the concepts of reincarnation and rebirth on the context of Buddhism. For example, in reincarnation, a person may appear many times in different forms after death while in rebirth, an individual does n ot have to return to the earth. In other words, the entity of the person does not return to the earth again. This comparison is usually done to a leaf growing on tree. There is always an eventual replacement of a withered leaf that has fallen off. Alternatively, there is a similarity to an old leaf but not the same as the original leaf. It is after many phases whereby an individual exudes the attachment of self and desire and the stage of Nirvana is reached (Steinfels, 2009). It is also a state of freedom from suffering and liberation. In that prospect, there are three practices or trainings of Buddhism. They include Sila that mean morality, good conduct or

Networking and data security - Assignment Example More often than not this kind of network of personal area network could also be interconnected lacking wires to the Internet or other even networks. To a larger extent this is true. Unlike other types of networks that are specifically fixed to an office location network wise, metropolitan area network span to the furthest boundary of a city. A metropolitan area network (MAN) can be referred to as a network that interconnects users in a geographic area or region larger than a large local area network (LAN) can cover but at the same time smaller than wide area network (WAN can cover. The statement is further true as the term MAN` is applied to the networks interconnection in a city into a single larger network. A database user, also referred to as a traditional user is individuals who are associated with passwords and schemas. For instance, an application or a person that logs onto the database, they use a database user (schema) as well as password. Database users are, therefore, able to create heavyweight sessions to the schemas that they are associated. An application user, on the other hand, can be an autonomous application process or a person that accesses information or data in the database. Unlike database users, application users do not own database schemas. However, they are able to create application sessions to databases via the middle tier. They are also able to create heavyweight database sessions via direct connection to the database. A database role is traditionally imagined to be a set of database privileges that applications, database users, or other database roles are granted. Database roles serve as intermediaries that map database privileges to database applications and users. On the other hand, an application user is often regarded as a set of application-define privileges associated with it and it is only granted to application users or to other application roles. An application role

English3 - Essay Example Commemoration of such an event has significant national unity influence as it promote spirit of patriotism among people. There are diverse reasons that support need to celebrate declaration of independence. The colonialists plundered natural resources and repatriated local wealth to their mother lands. This poses a real threat to future economic progress as limited natural input factor dictates level of performance. All nations that were formerly colonized have little resources left which means they have to rely on other economies and pay for what was previously available. Civil revolution has helped many colonies to escape the exploitation trap that was orchestrated by the imperialists. It is therefore worth to note that declaration of independence reminded the society of the dark past characterized with ravaged economy and impoverishment. Taking the case of pre-independence in United States, England dominated economic activity and reaped at the expense of the subjects. The young generation is particularly targeted by the spirit of national integration because if it were not for the forefathers and their relentless effort the fruits enjoyed today would not exist. The welfare of the society is instrumental in gauging level of improvement in the economy. Political policies that recognize the need to initiate gender mainstreaming can be attributed to declaration of independence. Colonial regimes were dominated by patriarchy with limited representation of women in the decision making institutions. The emergence of independence campaign has significantly boosted the recognition of rights of women. On the same note, consideration of local culture is critical in promoting an integrated education system. Colonial systems may not be consistent with the native socio-political structures hence yield setbacks. Some of the other contemporary matters that make declaration of independence concern human rights. Colonial authorities tend to promote

Disaster Recover Plan Assignment Example | Topics and Well Written Essays - 1000 words

Disaster Recover Plan - Assignment Example This is usually composed of representatives from all departments in the organization with specific expertise relating to the departments they represent. In case there is need to transport certain records or equipment to a different location, the transportation team will facilitate this process. For example, in case of a natural disaster such as a flood, key equipment and documents need to be moved to a secure location. This team may also help in the movement of staff and the team members when necessary, especially for large organizations. The logistical officer will be in charge of all the supplies used in the recovery process. In case of external support, the logistical officer should make arrangements to get the support and keep all records and agreements intact. This group of people will be responsible for ensuring that the safety of personnel and equipment is guaranteed. During a disaster, it is likely that the entire organization might be exposed to greater security and safety risks. The second step is to identify the key assets within the organization and the impact of each asset. This will help the disaster recovery team understand the value of each asset to the organization and the strategies to be used in protecting that asset. In addition, this step allows the organization understand the major threats against the business assets identified. Some of these threats include terrorism, hardware failure, cyber attacks and theft among others. The implementation of the recovery plan begins during the activation planning. This process is carried out by the recovery team or part of the team. This step helps in listing those systems that need to be restored, give the time estimates required for each system to be restored and give a clear communication plan between the recovery team members or groups. During this phase, all the staff members and recovery teams have been notified. The execution phase is

International Tourism Development Assignment Example | Topics and Well Written Essays - 750 words

International Tourism Development - Assignment Example One of the most notable projects of WTO is The Silk Road Project which revitalizes the ancient highways used by Marco Polo through tourism. This project was adhered to by 22 countries and stretches 12,000 km. Another is the creation of Task Force for Destination management which is a move to further decentralize tourism administration on a global scale. Some concerns of the task force include management of congestion at coastal destinations; economic measurement of tourism at the local level; destination marketing for cities; information and communication technologies; human resource development; and risk and crisis management at individual tourism destinations. This has significantly improved tourism destinations, especially in emerging economies.It is irrefutable that tourism depends on the economic conditions of different nations. Currently, this is reflected by the tourism activities of the growing economies like China, India, and Brazil. As economies grow, it is often expected t hat the level of disposable income also rises and a significant portion of this increase in income will be spent on tourism. This fact is mirrored by the current trend in tourism. As more emerging economies are growing, there is a stronger demand for tourism. According to the World Tourism Organization, tourism for leisure surpasses tourism for business purposes in 2005.Sociocultural factors specifically the perceived importance of taking holidays and vacations are improving demand for tourism. The global mentality which is the current trend also increases the attractiveness of travel.Technological innovation also has a significant impact on the tourism industry specifically on how tourism business is conducted. The advent of internet technology proved to be highly beneficial in the marketing efforts of tourism companies. Consequently, firms are able to market at a lower cost, reaching more geographic locations and market at a faster and more efficient way. Another role of technolog y is the facilitation of e-conferences for the benefit of members.

Earning a College Degree Essay Example for Free

Earning a College Degree Essay Earning a college degree has always been a very important goal of mine. My children are getting older and in a few short years will start looking into college themselves. It became more important for me now than ever to make my dream, my goal, a reality. There were many factors that came into play when I decided that this was the right time in my life to return to school. Being a non-traditional student, cost, flexibility, and accreditation were among the most important factors for me when choosing an online university. As my research into finding the right university continued, I found that Western Governors University had much more to offer their students than just an education. The financial aspect of returning to school was probably my biggest concern. I wanted to earn a degree, but didn’t want to be left with a hefty student loan payment at the end. Many of the online University’s that I looked into were â€Å"for profit† schools. Being inexperienced and new to this research I didn’t realize that there was such thing as a â€Å"non for profit† online University until I stumbled upon WGU. With affordable tuition, I knew that my dream could soon become reality. My children and husband are my number one priorities. They always have been, always will be. My time spent with them is precious and something that I would not give up for anything. The flexibility in classes and coursework that WGU offers has given me the perfect balance to be both a mother and a student. Since WGU is a competency based school, this allows me to spend less time on the material that I already know and concentrate more on the subjects that I am not as familiar with. Accreditation was another important factor for me. I didn’t want to spend the next 3 to 4 years going to school, spending countless hours reading and studying, only to find out that future employers would not take my degree seriously. Finding out that WGU is highly respected among businesses made my decision that much easier. There have been a few unexpected surprises along my journey thus far, with WellConnect being one of them. I never realized how much an online university could care about the health and wellbeing of their students. WGU also has some great mentors who not only offer encouragement, but push you to do the best and be the best that you can be. From my first inquiry of Western Governors University to now, I can say that, without a doubt, I made the right decision. I have finally found an online university who is just as committed to my success as I am. I would encourage anyone thinking about  returning to school as a non-traditional student to look no further than Western Governors University. With their low-cost tuition, flexibility, and accreditation to their amazing and caring mentors and their competency based program, WGU is definitely a perfect fit.

Quantitative And Qualitative Methodologies

Quantitative And Qualitative Methodologies This essay analyses the key viewpoints underpinning the theory and critically evaluate the suitability of quantitative and qualitative methodologies to undertake an empirical research into procurement practice through a literature review. However the way in which research is conducted may be conceived of in terms of the research philosophy subscribed to, the research strategy employed and so the research instruments utilised in the pursuit of a goal the research objectives and the quest for the solution of a problem the research question. The purpose of this essay is to discuss the research philosophy in relation to other philosophies; expound the research strategy, including the research methodologies and techniques that suits the proposed research aim (Jankowicz 2003a; Stevenson and Cooper 1997) The essay discusses the research philosophies; set out the approaches to research positivist and interpretivist; quantitative and qualitative studies, and how they are mixed. Denzin and Lincoln (1998) state that a research philosophy is a belief about the way in which data about a phenomenon should be gathered, analysed and used. The term epistemology (what is known to be true) as opposed to doxology (what is believed to be true) encompasses the various philosophies of research approach. Holden and Lynch (2004) argue that depending where the researcher sits on the continuum of these two extremes, their ontological stance will influence their core assumptions concerning the epistemology and human nature (Holden and Lynch 2004). However, Guyer and Wood (1998) argue that the purpose of science, then, is the process of transforming things believed into known: doxa to episteme. Creswell (2007) argue that before any type of research methodology or strategy is chosen, there should be a definition of what information is needed to respond to the research question. It is important to make explicit why one choose to collect information on a certain subject and not on another, and why choose to treat this case in the study and not the other (Creswell 2007). The research paradigm provides accepted methods of collecting data. The term paradigm refers to the progress of scientific practice based on peoples philosophies and assumptions about the world and the nature of knowledge (Collis and Hussey 2003, p:46) However, Jankowicz (2005) pointed out that the researcher must understand their own ontological position because it will determine what evidence is collected and what evidence is set aside in building the research argument, which is to do with ones epistemology. In the field of social science where the proposed research aim Supplier Relationship Management fits into, there has been increasing debate regarding the research methods and theory construction. Bryman et al (2008). Fish (1990) focused on the distinctions between and relative merits of the traditional objective or positivist approach and the alleged subjective approaches variously described as naturalistic, qualitative, phenomenological, and most recently interpretive. (Fish and Dorris 1990). Giorgi (1971) characterised traditional scientific approach as reductionistic, in reducing phenomena to operational definitions; deterministic, in that all phenomena are believed to have causes which can be duplicated; predictive, in that the goal is to predict behaviour; observer independent, in that the researcher tries not to influence the data; empirical, in that only observable data are to be examined; repeatable, so that the research can be replicated by other investigators; quantitative, in that the phenomena should be described in a measurable terms. So, traditional research examines variables in order to predict behaviour. (Giorgi, 1971) Giorgi (1971:21) posits that the essential question for the human science is not how do we measure phonomena? but rather, what do the phenomena mean? Hirschheim et al. (1985) state that both research traditions start in Classical Greek times with Plato and Aristotle (positivists) on the one hand, and the sophists (anti-positivists) on the other. After long, dark periods in European scientific thought, the renaissance of the discipline came in the sixteenth and seventeenth centuries. (Hirschheim and Klein 1985). Sandberg (2004) as referred to in Weber (2004), state that the alleged differences between positivist and interpretive research approaches can be characterised in a number of ways. One could argue whether Sandberg characterisation would be accepted widely. However, before the two different approaches are analysed their differences needs to be explored (Weber 2004). Weber (2004) describes how positivism and interpretivism supposedly differ in terms of their various metatheoretical assumptions. Morgan and Smircich (1980) argues that the subjectivist ontological position maintains that reality does not exist outside oneself, that ones mind is ones world, hence reality is all imagination. The polemic position to that of the subjectivist is the objectivist ontological position, which is one of realism (Morgan and Smircich 1980) Weber (2004) asserts this argument and stated that positivist supposedly believe that reality is separate from the individual who observes it. They apparently consider subject (the researcher) and object (the phenomena in the world that are their focus) to be two separate, independent things. In short, positivistic ontology is alleged to be dualistic in nature. In contrast, interpretivists believe that reality and the individual who observes it cannot be separate (Weber 2004). In a nutshell, that the perceptions about the world are inextricably bound to a stream of experiences that one has had throughout our lives. The life-world has both subjective an objective characteristics. According to Holden and Lynch (2004) objectivists contend the world will still exist as an empirical entity, made up of hard tangible and relatively immutable structures, independent of the cognitive efforts of individuals. The objective characteristics reflect what one constantly negotiates this meaning with others with whom people interact. In other words, it is objective in the sense that it reflects an intersubjective reality (Holden and Lynch 2004). Kuhn (1970) added, for positivists the objects they research have qualities that exists independent of the researcher. However, interpretivists believe that the qualities they ascribe to the objects they research are socially constructed they are product of their life-worlds. (Kuhn, T. S. (1970) Lee (1989) and Dubà © et al (2003) assert this argument and state that positivists tend to use laboratory experiments, field experiments, and surveys as their preferred research methods. They seek large amount of empirical data that they can analyze statistically to detect underlying regularities. In the other hand, interpretivists tend to use case studies, ethnographic studies, phenomenographic studies, and ethnomethodological studies as their preferred research methods (Weber 2004). Easterby-Smith et al (1991) argue that objectivist content that the relationship between man and society is deterministic, we are born into a world in which there are causal laws that explain patterns of our social behaviour. Alternatively, Dubà © (2003) argues that a statement made by a researcher is true when it has a one-to-one mapping to the reality that exists beyond the human mind (a correspondence theory of truth). On the other hand, interpretivists subscribe to a notion of truth whereby a researchers initial interpretation of some phenomenon conforms to the meaning given to the phenomenon through the researchers lived experience of it (Weber 2004). Searle (1999) find the alleged differences between positivist and interpretivist in relation to ontology to be vacuous. He admits that some kind of reality exists beyond our perception of it! Kuhn (1970) recognises the inherent limitations of the knowledge they seek to build. Positivists understand fully that their culture, experience, history, and so on impact the research work they undertake and thus the results of their work. In Kuhns (19970) view, irrespective of whether researchers believe in an objective reality that exists beyond the human mind or a socially constructed reality, all accept that the artefacts they build to understand the world (theories, frameworks, constructs, etc) are socially constructed. Kuhn (1970) goes on to argue that research is a continuous journey to find improved ways to understand this reality. It is apparent from Lee (1989) and Dubà © (2003) argument that positivists researchers fully understand that we have no way of knowing the world as it really is, at least for the moment. In this light, pragmatically they can place little value on a theory of truth that relies on the level of correspondence between research statements they make and an unknowable thing (Weber 2004). Dubà © (2003) added, there are no differences between positivist notions of validity and interpretivist notions of validity. The position of the Author in this debate leans toward notion that tries to measure reality in a research. There is no way of knowing reality, so how can one know whether his measure of reality, whatever reality might be, is valid? What is believed to be a reality at one particular point in time, may change, for example, with new knowledge, at a later point in time, therefore it was never a true reality originally then! Fundamentally, the Author sees little difference in positivist and interpretivist notions of reliability. Both groups of researches are concerned ultimately with the idea of replicability. In the case of positivists, the strategies and methods for achieving replicability are more straightforward because the research methods they tend to use are well-defined and routinized. Weber (2004) argue that in the case of interpretivists, replicability is a more-difficult goal to achieve because the research methods they tend to use are less well-defined and the subjective nature of interpretation is acknowledged explicitly. For these reasons, interpretivists try to lay out clearly their research methods and ways in which they have achieved certain kinds of interpretations. (Weber, 2004). Klein and Myers (1999) questioned whether there is any difference between positivism and interpretivism. The Author believes that the differences lie more in the choice of the research methods rather than any substantive differences at a methatheoretical level. In this regard, researchers who labelled themselves as positivists tend to use certain kinds of research methods in their work experiments, surveys, and field studies. Interpretivists, on the other hand, tend to use other kinds of research methods in their work case studies, ethnographic studies, phenomenographic studies, and ethnomethodological studies (Klein and Myers 1999). The researcher believes that there are large-scale social forces affecting and influencing individuals interpretations and behaviour (Collis and Hussey 2003). Although there are a number of variations in terminology, the majority of literature appear to use the terminology positivist to describe the quantitative approach, which is objective in nature as mentioned in this essay, and employs inductive research methods; and interpretivist to describe the quantitative approach which is subjective in nature and employs deductive research methods. (Davies, 1968). The issue of quality and quality criteria in social science research is a topic that has become increasingly prominent in methodological discussions in recent years. Gurtler and Huber (2006) argue that qualitative and quantitative methodology textbooks as well as research reports often use ambiguous language in the sense that many formulations cannot be assigned unequivocally to one of the main methodological orientations (Gurtler and Huber 2006). However, Gilmore and Carson (1996) argue that the adaptability and flexibility of qualitative research methods and techniques throughout the entire research process have many advantages. For example, at an early exploratory stage of research, qualitative methods allow the researcher to become familiar with the area(s) of interest, explore the fields and consider the dimensions involved because of their open-ended, non-pre-ordained nature (Gilmore and Carson 1996). Cohen and Manion (1994) as referred in Milliken (2001), who identified two competing views of the social sciences, modify this perspective. One view posits that social sciences are essentially the same as natural sciences and are therefore concerned with discovering natural and universal laws regulating and determining individual and social behaviour (Milliken 2001). The other view emphasises how people differ from inanimate natural phenomena and from each other, while sharing the rigour of the natural sciences and the same concern of traditional social science to describe and explain human behaviour. Hunt (1994) supported by Van Eijkelenburg (1995) argued that it is time for the advocates of both qualitative and qualitative methods to declare a à ¢Ã¢â€š ¬Ã‚ ¦rhetorical cease-fire (Van Eijkelenburg 1995). Kirk and Miller (1986) advocated that qualitative research is implicitly orientated to the question of validity. The polemic approach to quantitative research is qualitative research. Medawar (1969) argues It is no use looking to scientific papers for they not only merely conceal but actively misrepresent the reasoning that goes into the work they describe (Medawar 1969). However, Crescentini and Mainnardi (2009) state that what makes a research question a qualitative one is precisely the nature of this combination: qualitative goals are different from quantitative ones, and qualitative questions are asked in a particular way and refer to qualitative contents. The peculiarities of qualitative goals reside in the way the question is framed a need to describe, verify or understand. A qualitative research question must explore a qualitative argument in a qualitative way. The question has to be grounded in a qualitative argument. (Crescentini and Mainnardi 2009) Some literatures suggest that there is quite often a mismatch between the rationale for combining quantitative and qualitative research and how it is used in practice. (Bryman 2009). Fisher (2004) makes an interesting observation on the subject of mixing methods. If you take a realist stance, then aspects of an interpretivist approach could be brought in as useful adjunct to the research. But they also claim that the reverse is not true. If you are doing interpretivist research, then there is no way that an element of realism (or more seriously an element of positivism) can add to it. This is because of the positivists view of the world i.e. things are real and can be measured, which would totally contradict the interpretivist perspective of the world. Robson (1993) argues that triangulation in its various forms, or multiple methods, of obtaining information can be valuable if two sources give the same message, then to some extent they cross-validate each other and provide a means of testing one source of information against other sources which results in more credible results. According to Denzin (1978:291) triangulation as a form of combination of methodologies in the study of the same phenomenon has become more widely accepted now as a means of ensuring validity. There is a distinct tradition in the literature on social science research methods that advocates the use of multiple methods. This form of research strategy is usually described as one of convergent methodology, multimethod/multitrait (Campbell and Fiske, 1959). Jick (1979) argue that these various notions share the conception that qualitative and quantitative methods should be viewed as complementary rather than as rival camps. In fact, most textbooks underscore the desirability of mixing methods given the strengths and weaknesses found in single method designs. Yet those who most strongly advocate triangulation (e.g., Webb et al., 1966; Smith, 1975; Denzin 1978) fail to indicate how this prescribed triangulation is actually performed and accomplished. However, Gill and Johnson (2002) claim that multi methods are infrequently applied mainly due to the fact that multi methods are extremely time consuming and can be costly. Indeed, they argue that where methods are well separated from one another, this approach would be impracticable (op cit). Despite this view, Easterby-Smith et at (1991) argue that in recent decades there has been a move towards researchers developing methods and approaches (triangulation) that provide a middle ground and some bridging between the two extreme viewpoints. Triangulation of methods certainly appears to be gaining support and as Hussey and Hussey (1997) point out, triangulation can overcome the potential bias and sterility of single method approaches. Rohner (1977) argue that in all various triangulations designs one basic assumption is buried. The effectiveness of triangulation rests on the premise that the weaknesses in each single method will be compensated by the counter-balancing strengths of another. The proposed research aim, as mentioned early in this essay, is the Supplier Relationship Management. As the research will require use of e-survey, semi-structured and structured interview the mixed method approach revealed to be the most suitable. There are both quantitative and qualitative research elements in the research. There are quantitative data deriving from the e-survey and there are qualitative data deriving from answers to open questions in the e-survey and the semi-structured interviews. The chief rational for using this combination of sources of data is that it was felt from the literature review for this essay, that a complete picture could not be generated by any one method alone. Each source of data represents an important piece in a jigsaw. (Bryman, et al 2008).

Moreover, it has a key role to play in sustainable construction, since it needs less effort in its manufacture. These facts have not only led to many inventions in the field of concrete but have also led to many studies in order to improve its quality, reducing the cost of implementation and make the concrete friendly with the environment; besides, amending its aesthetical appearance when it is used as a structural construction members. Nowadays, It can be seen that as a result of the research progressions concerned the concrete technology, various types of concrete such as High Performance Concrete, Ultra High strength concrete, Light Weight Concrete, Architectural Concrete and Self compacting concrete (SCC) are commonly heard not only among engineering Society but ordinary people also. In this prospective, the awareness and more knowledge regarding the concrete types should be considered. In fact, civil engineers should have more awareness and information about concrete types so as to be able to keep themselves abreast with the most recent developments, new technological innovations and future prospects. Regarding the SCC, it can be considered as a one of the recent developing types of contemporary concrete. It is an innovative concrete mixture that can be mold into place without the use of vibrators to form a product free of empty spaces within the formwork. It is commercially known by various names such as self-consolidating concrete, self-compacting concrete, self-leveling concrete, or rheoplastic concrete (Mehta and Monteiro 2006: 476). The Prototype of (SCC) was first developed in 1988 in Japan, by Professor Ozawa in 1989 at the University of Tokyo (Okamura and Ouchi 2003).However; the name of SCC was given to this Prototype by Okamura of the University of Tokyo. The aim of this project is to review or gain understanding about SCC in terms of its ingredients, mixture requirements and mechanism for achieving self-compatibility depending on previous researches. It also evaluates the results of using this type of concrete in some modern implementations. Finally, it demonstrates the benefits and potential disadvantages of using SCC in terms of safety, economy, and construction quality. 1. Historical reasons for development of SCC According to Goodier (2003:405), the initial emergence of Self compacting concrete was in Japan in the late 1980s and its subsequent introduction into Europe through Sweden in the mid- to-late 1990s. In the 1980s, the problem of the durability of concrete structures and acceptable compaction were the main subject that was considered in Japan; meanwhile, the skilled workers were required in order to achieve durable concrete and acceptable compaction. It seems to be the lack of the numbers of skilled workers in Japans construction industry at this time was the main reason for decrease in the quality of construction work. One solution for achievement of durable concrete structures was the using of self-compacting concrete, which can be compacted into every corner of a formwork, completely by means of its own weight and without the need for vibrating compaction. This means that it can be gained sustainable concrete structures and acceptable compaction by using minimum number of workers and equipment (Fig.1).Moreover, the use of SCC was also implemented to provide economic, social and environmental benefits over conventional vibrated concrete construction. (Okamura and Ouchi, 2003:5)The conception of this type of concrete was proposed by Professor Hajime Okamura in 1986 who Studied the development of self-compacting concrete and comprised a fundamental study on the workability of concrete (Okamura and Ouchi 2003). 2. Ingredients and requirements of SCC mixture With respect to its composition, SCC includes the same components as conventionally vibrated normal concrete, which are cementitious materials, different sizes of aggregates, and water, additives and admixtures. On the other hand, in the SCC, high volume of super plasticizer for reduction of the liquid limit and for better workability, the high powder content as lubricant for the coarse aggregates, as well as the use of viscosity-agents to increase the viscosity of the concrete have to be taken into account (Dehn et al. 2000). Regarding to the requirements of SCC mixture, a concrete mix can only be classified as SCC if the requirements for all the following three workability properties are fulfilled which are filling ability, Passing ability, and Segregation resistance (Abdul Hameed 2005). Filling ability or flow ability means that, the SCC must have the ability of to fill a formwork entirely under its own weight. According to the European Guidelines for Self Compacting Concrete (2005: 20), the tests that are used for assessing filling ability of the fresh SCC are Slump-flow, and Kajima box. Passing ability means that the SCC must have the ability to flow through restricted places, such as spaces between steel reinforcing bars, sharp corners, and small openings, without using any means of vibrators (to flow by its own weight), also without produce any blocking or hindrance during its use. According to the European Guidelines for Self Compacting Concrete (2005: 20), the tests that can be used to determine passing ability are U-box, L-box, Fill-box, and J-ring test methods. Segregation resistance means that the SCC must meet the filling ability and passing ability with Homogeneous composition during and after the process of transport and placing. It is generally accepted that the three main properties of fresh self-compacting concrete must then be maintained for required period of time after mixing. 3. Mechanism for achieving self-compact ability of fresh concrete Okamura and Ouchi (2003:5 ) suggested that In order to achieve self -compact ability of fresh concrete, deformability of past ( mortar) and resistance to segregation between aggregate particles and mortar when the concrete flows through the restricted zone of reinforcing bars, have to be considered. Okamura and Ozawa (1995) have utilized the following methods to achieve self-compact ability of fresh concrete. Firstly, they limited the amount of aggregate content (coarse aggregate  ­ 50% of the concrete volume and sand ­ 40% of the mortar volume).Secondly, they used low water/powder ratio, with higher dosage of superplasticizer admixture. According to SHETTY (2005:573), using superplasticizer which is used with concrete components as an essential chemical admixture, leads to increase the workability of fresh concrete without regard to reducing water content in the concrete mixture. When concrete is placed in to the formwork, the relative distance between the concrete particles will decrease. As a result, the frequency of collision and contact can increase and consequently, internal frictions between concrete particles also increase, especially near hindrances. Research has found that the energy which is required for flowing the concrete during the casting is consumed by the increased internal friction between particles, and resulting in blockage of aggregate particles to flow through confined places. For this reason, limiting amount of coarse aggregate, whose consume more energy, to a level lower than normal will increase the efficiency of concrete flow ability and avoid concrete particles from this kind of blockage. To prevent the interlocking (blockage) incidence of coarse aggregate when the concrete is poured through obstacles, highly viscous past is required. Since the concrete which has a high viscosity prevents localized increases in internal stress as a result of the approach of coarse aggregate particles (Okamura and Ouchi 2003:6). 4. Some applications of SCC Based on the researches which have been performed on SCC over the last two decades, it can be said that the use of SCC has been increased dramatically. It is commonly used in place of traditional concrete not only to reduce time of construction projects but also to reduce the cost of construction projects. According to Okamura, Whatever conventional concrete can do, SCC can do better, faster, and cheaper, especially for concrete elements with special textures, complex shapes, and congested reinforcements (Mamaghani et al. 2010:5). It can be seen that there are a range of using of SCC around the world. Many researches show that this type of concrete is commonly used within cast-in-place (in field) and precast construction. Furthermore, it is also used in the structural and architectural concrete sections where the tightness of steel reinforcement and /or surface quality is required. However, other implementations of SCC include drilled piers, caissons, bridge abutments and walls. In Japan, the first use of SCC was in 1991 for the construction of bridge towers (Daczko and Vachon, 2006:638). While the first large-scale project using SCC was the Akashi-Kaikyo Bridge, which completed in 1998. It is estimated that the construction time of this project was reduced by 20%, from 2.5 to 2 years due to the use of SCC (ibid.). A second implementation was performed, in 1998, for the building of the walls of a natural gas tank for the Osaka Gas Company. The estimated amount of SCC that was been using during the construction is approximately 12000 m3. It was observed that the construction time of the project was also shortened from 22 to18 months meanwhile; the number of labours worked in the project was reduced from 150 to 50 (ibid.). In Sweden, the Sodra Lanken Project (SL) was one of the largest infrastructure projects that were implemented by using SCC. The total cost of this project was estimated at approximately 800 million USD. Ouchi et al. (2003) point out that the SL project included seven major junctions, with bridges, earth retention walls, tunnel entrances and concrete box tunnels; the overall length of the rock tunnels were 16.6 kilometers. Also, the volume of concrete used in the project estimated at 225,000 cubic meters. It was observed that SCC was used in the project because it included structural sections that were required high demands on aesthetics, and at the same time they were difficult to compact by normal vibration. Recently, the New York State Department of Transportation (NYSDOT) has used significant amounts of SCC. Mamaghani et al. (2010: 5) report that the current projects in the New York State include the use of SCC for prestressed, high performance concrete bridge beams on the Brooklyn-Queens Expressway from 61st Street to Broadway in New York City. According to a NYSDOT official, The performance of SCC has been excellent. NYSDOT is achieving very good quality with a minimum of defects. There has been a slightly higher cost for admixtures, but NYSDOT saves on labor. It can be anticipated that, in the future, concrete elements or buildings will be designed considering SCC from the start with shapes, textures, and structures that would be impossible to achieve with normal concrete. 6. The advantages of using SCC in engineering implementations Improved concrete construction environment The SCC is considered an environmentally friendly material. Firstly, regarding the construction site, the SCC can eliminate the need for vibration to compact the concrete; since SCC has ability to fill the form work completely under its own weight. The compaction of fresh concrete by vibration is generally recognized as a heavy physical job and an unpleasant activity in the concrete construction process. Moreover, using the vibration can also cause high noise levels which are not good for public health; especially the health of the operators. Secondly, the acceleration generated by vibrators can reach 0.70 to 4m/s2 and has potential to injure the vibrator operator. Hence, eliminating the vibration significantly improves health and the environment on a concrete construction site (Li 2011). It can be said that some skills and experience are needed for vibrator operators in compacting fresh concrete in order to gain a satisfactory concrete. Lack of experienced workers in many regions ma y lead to decline the quality of concrete. It is generally accepted that the application of SCC can solve this problem and ensure consistent high quality for concrete structures. Cost-efficient production With respect to the required number of labours on the construction project compared with conventional (normal) concrete types, the SCC needs less number of workers and shorter times for placing (casting). It is generally believed that by using SCC, the process of production can be accelerated, and the quality of concrete structures can be improved as well. According to Peterson (2008:66), the elimination of vibration means rationalised casting technique with less need of personnel and/or more rapid production cycles and thereby presumptively reduced production costs. New opportunities with respect to architectural and structural applications SCC benefits structural and architectural applications. New types of structural elements, which were not possible to be produced by traditional concrete, can be produced by using SCC because these types of structural elements include different types of steel or concrete structural elements with more complex shapes, which are thinner with a much heavier reinforced cross section. With regard to the construction of heavy structure (mega structure) fields such as multistory building, high rise building or ultra-high rise building, since the SCC does not need any vibrators and finishing surface tools, it means that it reduces lifting of heavy equipment and reduces handling of fresh concrete by labours. Also, there is no need of repairs to hardened concrete as there are no chances for producing any remarkable voids. With respect to construction consideration, Ouchi et al. (2003:18) found that When placing a new layer of SCC on old SCC, the bond between the old and new SCC is equal to or better than in the case of conventional vibrated concrete. On this basis it may be inferred that the normal vibrated concrete needs vibration to provide well compacted concrete, while SCC will not need the vibration and consequently it will not destroy the concrete. Regarding the durability of SCC, researches have shown that ingredients of SCC and the avoidance of using vibration have a significant role in improving the microstructure of the concrete (Holton 2004). The ingredients and avoidance of using vibration acquires the concrete many benefits. First, they gain the concrete lower surface permeability and absorption against harmful chemical materials such as chlorides and carbon dioxide which have a negative effect on the durability of concrete. Second, they improve the resistance of the concrete against freezing- thawing which the concrete may be subjected during different seasons. Finally, they play a key role in producing a good bond between the concrete materials and the steel reinforcement after the concrete hardening. Another advantage of the SCC is that, it can be used when the normal placement of concrete is difficult e.g. tunnel linings, heavily reinforced structures, prestress concrete structures and other inaccessible places. One example is the design of the Millennium Tower in Vienna, which is described as it had been impossible to build without using SCC (Peterson 2008:66). Moreover, Using SCC for the construction of tall building, bridge tower, and tunnels leads to increase the use of concrete pumping. Nowadays, by using special high- pressure pumps, SCC can be pumped distance as far as 1400m horizontally or as high as 420m vertically (Li 2011:130). 7. Disadvantages and obstacles for the implementation of SCC Absence of acceptance SCC Despite the fact that the SCC has a great numbers of stunning and successful applications; it was only hesitantly accepted by the industry. This could be attributed to a number of reasons (Holton 2004).First of all, the standard specification tests that were used for testing and evaluation conventional concrete was no longer useful for SCC. As a consequence, it was very difficult to smoothly put SCC into practice; also, before using SCC, the intensive preparation efforts were required in the laboratory in order to achieve an appropriate quality. Second, the sensitivity of SCC is increased proportionally with change of its mix proportions (particularly the water content) or with change of the environment such as temperature variations. This increased sensitivity produces an extra hindrance to the wider use of SCC as it puts a prices working at the production field (ibid.). Potential disadvantages and obstacles of using SCC Based on the recent studies, despite the possible benefits of SCC compared to normal concrete, it can be seen that the implementation of the SCC is still noticeably limited. According to Peterson (2008:67), the obstacles for increased application of this type of concrete can be attributed to technical and non- technical aspects. In the SCC, the quality of mix design and the conditions of casting concrete should be considered; slight differences in mix proportions or during its casting may cause a number of technical quality problems that may pose as hindrances for future use of SCC. Despite of the intensive and extensive studies on SCC, it can be seen that there are still some unsolved technical problems and a great number of technical difficulties related to SCC. Peterson (2008:67) described these problems in many aspects; such as the problems related to the quality production of the ready-mix design and the Problems related to the hardened SCC especially when there is a low surface quality which leads to reduce fire resistance due to spalling, increase cracking owing to early shrinkage. It is widely accepted that SCC tends to dry faster than traditional concrete, since there is slight or no bleeding water at the surface before it is hardened. For this reason, SCC should be cured when it is practicable after placement to avoid the incidence of surface shrinkage cracking. Moreover, Peterson (2008:71) indicates that although the SCC has been considered as one of the main important invented technology for a more rational way of building with cast in-situ concrete; there are some projects where SCC has led to create technical problems such as concrete segregation with non-acceptable surfaces, concrete cracking owing to plastic shrinkage and formwork failure due to the high form pressure that may be produced as a result of the flow ability feature of SCC. It would appear that further studies are required to achieve a durable and fully satisfying concrete product. Conclusion It can be concluded that SCC helps to improve the environment of the construction locations (reducing noise produced in the plants and construction fields) and reducing the exposure of labours (Reduction manpower) where concrete is being casted. In the other word, the SCC is an ideal type of concrete that can be used for narrow spaced of reinforcement and architectural demanding sections, or, in more general , for all structural applications where require higher efforts in order to gain sufficient compaction. Furthermore, it can be seen that SCC offers many other benefits for the precast, prestressed concrete sector and for cast-in-place construction such as eliminated problems related to vibration, faster construction, gaining higher strength and better quality for the concrete after hardening. On the other hand, Although SCC can have many advantages and significant effects on the engineering applications such as its importance role in reducing the project construction time period, it can be said that special attention should be concentrated on particularly, in terms of selection the suitable ingredients of SCC mixture before the production (mix design of SCC). It can still be expected that, in the future, using SCC will help engineering designer (architects and structural engineers) to design concrete sections or structural elements which would be impossible to achieve with conventional concrete. Based on these facts it can be said that SCC will have a bright future.

Female Genital Mutilation Essay -- essays research papers fc

The practice of female genital mutilation, also known as female circumcision, occurs throughout the world, but it is most common in Africa. Female genital mutilation is a tradition and social custom to keep a young girl pure and a married woman faithful. In Africa it is practiced in the majority of the continent including Kenya, Nigeria, Mali, Upper Volta, Ivory Coast, Egypt, Mozambique and Sudan. It is a cross-cultural and cross-religious ritual, which is performed by Muslims, Coptic Christians, Protestants, Catholics and members of various indigenous groups.   Ã‚  Ã‚  Ã‚  Ã‚  Female genital mutilation is usually performed on girls before they reach puberty. It is a procedure where either part or the entire clitoris is surgically removed leaving a reduced or total lack of sexual feeling. This procedure is an attempt to reduce the sex drive of women, making them less likely to be sexually active before marriage or engage in extra-marital affairs. Although this procedure can be seen as a means to control a woman’s sexuality, the act of female circumcision determines the gender identity of women. A circumcised woman is a virgin, ready for marriage and to bear children for her husband, â€Å"Girls who are infibulated will probably not find husbands. In most cases they will become outcasts.†   Ã‚  Ã‚  Ã‚  Ã‚  Female genital mutilation is not a new practice. In fact circumcised females have been discovered among the mummies of ancient Egyptians. A Greek papyrus dated 163 BC refers to operations performed on girls at the age they received their dowries. A Greek geographer reported the custom of circumcision of girls he found while visiting Egypt in 25 BC. In Africa female circumcision has been reported in at least twenty-six countries and can be viewed as a public health problem â€Å"because of its wide geographic distribution, the number of females involved and the serious complications caused by the operation.†   Ã‚  Ã‚  Ã‚  Ã‚  Female genital mutilation is practiced in three major forms: â€Å"Sunna† circumcision, Clitoridectomy, and Infibulation. Sunna circumcision consists of the removal of the tip of the clitoris and/or the prepuce (covering). Clitoridectomy, also referred to as excision, consists of the removal of the entire clitoris (both prepuce and glans) and removal of the adjacent labia. Infibulation, also referred to as phara... ...s, and aunts footsteps, which would bring shame against herself and tarnish her family honor. Female genital mutilation is such a brutal and barbaric practice that it is amazing it is still occurs today. The health hazards associated with it should be enough to have it terminated. However, the reasons women have forgoing through with the operation is the custom of female genital mutilation is so engrained in their sociocultural system. The importance of family honor, virginity, chastity, purity, marriageability, and childbearing in these societies cannot be overstressed. Therefore in the minds of the people who adhere to this belief, the benefits gained from this operation for the girl and her family far outweigh any potential danger.   Ã‚  Ã‚  Ã‚  Ã‚   Works Cited Female Genital Mutilation.

Ethics/Legal/IEP Essay -- essays papers

Ethics/Legal/IEP Essay In the treatment of those individuals labeled as disabled, be it physically, mentally, or a combination thereof, we are faced with many challenging ethical questions. The first and foremost of these is, what is ultimately, â€Å"the right thing to do.† While we may or may not agree on the answer to this question, as well as those that follow, many advances have been made in our society to deal with disabled individuals in the most humane and ethical way possible. What is the right thing to do? Is there an ultimate resolution? In 1975, Public Law (PL) 94-142 was passed. This law has several parts, each pertaining to a different aspect of discrimination, or nondiscrimination, of disabled persons. This law was passed in hopes of avoiding not only the horrific scenarios found in Nazi propaganda films such as Selling Murder, but further to guarantee all disabled individuals a fair chance at life: to live to the fullest extent of their capabilities and fulfill their potentials. In the film, Selling Murder, Nazi officials convey to the public that disabled people are a threat to the world community, and that they are living a â€Å"life without existence.† It goes further and says that not only should those who are disabled be quarantined and banished from society, but for their own sake they should be sterilized, and ultimately killed. Labeling the mass deaths of disabled persons â€Å"mercy killings,† the film explains how they, the disabled, are unable to function as â€Å"real† human be ings, and that if they had the mental facilities to make the choice, they would choose death over such a menial existence. Showing gruesome photos of the severely physically disfigured, the propaganda seeks not only to convince, but to scare the masses into agreement. On the other hand, films such as Regular Lives demonstrate the ability of disabled individuals not only to survive, but to flourish and better their communities through their own efforts. It demonstrates the necessity to include disabled students in any and all ways possible in order to help them adapt to a social environment as normal as is possible. PL 94-142 states that all disabled students are guaranteed a FAPE (free and public education). With this comes the formulation of an IEP (individualized education plan). This grants students a goal guided objective list for their education. The ... ...ther teacher or administrator to explain evaluation results to those involved. Why does it matter? What is the relevance/necessity of making moral judgments when formulating a course of action? Disabled people have been discriminated through time. They have been played as Jesters for entertainment, banished as havens for evil spirits, and massacred simply for being different. They have been subject even to sterilization, seen as people unfit to breed. We are forced to ask ourselves- why then, does it matter? Hardman states on page 52, â€Å"Social justice and equality for all people should be of paramount importance in the design and delivery of all curricula.† Fair and equal treatment of disabled persons matters because they, like all other citizens of this country, are people. They are born in this country with the guarantee that they will be granted â€Å"life, liberty, and the pursuit of happiness.† With this in mind, it is our moral and ethical obligation to â€Å"hold these truths to be self evident, that all men are [indeed] created equal.† This country was founded on these beliefs, and as we continue our progress forward with laws such as PL 94-142, we support this creed.

I have lived here for little less than four years. my name is tanner l. beltran. that is as far as i know of who i am.a label a person gave to me upon birth. a struggle of finding myself, knowing my identity as a person and my place in this life, are completely unkown to me. day to day i seek for this answer, finding it nill. to be quite frank, i have not graduated high school. I attempted going back to finish my ''much needed to survive this candy-land extistence'' education which was quite minimal in gaining for i had only 3 credits needed to obtain a peice of glorified paper that states i completed requirements to become proficient in facing the real world. Without any idea of who you are and what you are supposed to do in life, it may seem coping with this so called 'reality' is harsh.For me it is. struggling for identity and self acceptance from others, facing inner compications that only add to my horror that i may never figure out my own life. to quote Grace Hansen ''Dont be a fraid your life will end; be afraid that it will never begin.'' this is something that i am deathly afraid of; afraid i will i fail the one person who cherishes who i am to her. But in all I feel I am failing my self. And that takes away all my hope to ever succeed.   Ã‚  Ã‚  Ã‚  Ã‚  You see the prominent people never believed in me or had faith in my abilities. At least not the ones that should have. They faltered in early judgement of me at quite an early age. I feel it has been that inflicted inhibition that makes me fear failure more than being alive. that judgement makes finding myself brutally agonizing. In additon to this loss of mistaken identity of who I think I am, finding what I am supposed to do in my existent as a person of this nation falling to all hell, I need a piece of paper that states I meet requisetes to pursue any given career. Why do I need that piece of paper? What is its nominal meaning? What does it represent?

Most Politically and economically stable country

What country do you believe is the most politically and economically stable country to live in and why? Personally, I believe that the most politically and economically stable country to live in the world is Finland. The country is an ideal place to live in as it very few political concerns and few economic problems. Basically, for any country to be politically stable, it first has to learn discipline and adhere to moral standards. In this regard, Finland has consistently maintained very low levels of corruption. In the country, there are almost no reported corruption cases such as abuse of power while in public office, nepotism, bribery, extortion, graft, embezzlement, and cronyism. As a result, based on the Transparency International Corruption Perception Index, the survey which determines the level of corruption all countries in the world, Finland has consistently ranked number one, along with Denmark and New Zealand, among the least corrupt countries in the world. In other words, people living in Finland take comfort in knowing that all the taxes that they pay are put into good use since there is almost no corruption in the country. In addition, low corruption levels could also mean that the budget allocation for every department is free from kickbacks, which are usually illegally taken by public officials, and can lead to favorable gains such as road constructions, establishment of infrastructures, and improvement of public transportation, among others. Moreover, considering the low levels of corruption, it is safe to say that the country is lead by officials who have a genuine concern for the welfare of their people and who place the nation’s interest above anything else. In addition, these leaders can also serve as good examples other countries around the world. Furthermore, another notable aspect of the country is its relatively powerful economy. Basically Finland is a country that is highly-industrialized and has a free market economy, which rival that of other European economic powerhouses such as Germany and the United Kingdom. The country is also a key player in foreign trade as it also has large manufacturing companies of vehicles, machinery, chemicals, forestry products, and electronics. Moreover, the country has also been cited as the most competitive country from 2003 to 2005 and in 2006 for its research, development, and innovation, particularly on information technology. This is best shown in the success of Nokia, the leading mobile phone company, which has greatly contributed to Finland’s economic success. Other companies that are major contributors to the country’s economy include Akey Finnyards, which manufactures the largest cruise ships in the world, and Store Enso, which is the largest manufacturer of paper in the world. However, aside from contributing to Finland’s economic growth, these companies in the industry have also generated more jobs for the people living in the country. In addition, the low levels of corruption have also lead to more investors in the country, and as a result, the prices of goods have not dramatically increased. In short, I believe that Finland’s stable economy and progressive economy have made it one of the world’s most ideal countries to live in. Â

Methods Fourteen (five male) patients aged > 16 years were recruited from the diabetes clinic at the Royal Children’s Hospital. The continuous glucose monitoring syste m (CGMS) was attached at a weekend when alcohol consumption was planned for one night only.For each patient, the 12-h period from 18. 00 h to 06. 00 h for the night with alcohol consumption (study period) was compared with the same period with non-alcohol consumption (control period) either 24 h before or after the alcohol study night. Thus, each subject was his /her own control. Glycaemic outcomes calculated from continuous glucose monitoring included mean blood glucose (MBG), percentage of time spent at low glucose levels (CGMS < 4. 0 mmol/l), normal glucose levels (CGMS 4. 0–10. 0 mmol/ l) and high glucose levels (> 10. mmol/ l) and continuous overall net glycaemic action (CONGA). Results The mean number of standard alcohol drinks consumed during the study period was 9. 0 for males and 6. 3 for females. There was no difference in percentage of time at high and normal glucose levels in the study and control periods. During the control period, there was a higher percentage o f time with low glucose levels compared with the study period (P < 0. 05). There was an increased level of glycaemic variation during the study time when compared with the control period.Conclusions In an uncontrolled, social context, moderately heavy alcohol consumption by adolescents with Type 1 diabetes appears to be associated with increased glycaemic variation, but not with low glucose levels.

Whilst the effects of alcohol consumption upon glycaemia have been well described in a controlled setting [3– 6], little is known about the impact on glucose levels of alcohol consumption by adolescents within an ambulant, social context.The purpose of this project was to utilize continuous glucose monitoring to study the impact of social alcohol consumption on glycaemic control in a group of alcohol-using adolescents.  © 2006 The Authors. 830 Journal compilation  © 2006 Diabetes UK. Diabetic Medicine, 23, 830–833 Review article 831 Patients and methods This study was approved by the Human Ethics Research Committee of the Royal Children’s Hospital (RCH). That approval was contingent upon the fact that the investigators should not be seen to encourage underage drinking in adolescents.Consequently, we only approached adolescents who we knew were drinking socially and, despite our previous counselling, elected to continue to drink alcohol on a semi-regular basis. We recruited 22 adolescents with Type 1 diabetes from the RCH diabetes clinic. The adolescents were considered eligible only if > 16 years old and parental/patient consent was obtained. HbA 1c (Bayer DCA 2000 immunoagglutination method, Calabria, Barcelona, Spain) was measured, and diabetes duration and insulin doses were recorded. The MiniMed continuous glucose monitoring system (CGMS) was attached to the study patients over a weekend period.Patients were required to have an alcohol-free period for at least 24 continuous hours during the weekend trace period. A diary was kept of activities during the trace period (insulin injections, meal, snacks, dancing, alcohol consumption, sport). There was no change in insulin doses between study and control periods. In the evening when alcohol was consumed, patients were asked to recall how many and what type of drinks were consumed and how inebriated the y became. Patients recall of alcohol consumption was converted to ‘standard drinks’ (one standard drink contains the equivalent of 12. ml 100% alcohol) using The Australian Alcohol Guidelines [7]. CGMS data was recorded between 18. 00 and 06. 00 h on the evening when alcohol was consumed (the study period) and between 18. 00 and 06. 00 h on the evening when no alcohol was consumed (the control period). CGMS data were only analysed if there had been regular calibrations with intermittent capillary blood glucose readings at a maximum of 8-h intervals. Each CGMS trace was qualitatively and quantitatively analysed using mean glucose values, per cent time in glycaemic ranges and ontinuous overlapping net glycaemic action (CONGA) [8]. CONGA values were calculated to assess glycaemic variation over 1-, 2- and 4-h intervals. Low glucose values were defined as CGMS values < 4 mmol/ l, normal glucose values when CGMS values were 4– 10 mmo/ l and high glucose values when CG MS values were > 10 mmol/ l. Each patient acted as their own control with study periods and control periods being compared. Inter-individual values were grouped for comparison. Differences between study and control periods were analysed using paired t-tests. Analyses were done in Stata [9]. ales and nine females. The mean age was 18. 5 years (range: 17. 4 – 19. 5). The mean duration of diabetes was 9. 4 years (range: 3 – 16. 3). Six of our subjects took four insulin injections per day and eight took two injections daily. The mean insulin dose was 1. 1 units /kg/day (range: 0. 7 –1. 8), and the mean HbA1c was 9. 6% (range: 8. 2 – 10. 8). Activities during the study period Thirteen subjects had dinner before drinking and only one subject did not consume any food before going out. Three subjects ‘danced a lot’ and six subjects went dancing but did not dance a lot.Ten subjects had something to eat after drinking. Alcohol consumption during the st udy period The mean number of alcohol drinks consumed on the study night was 9. 0 (range 3–16) for males and 6. 3 (range 3–14) for females. All the females consumed pre-mixed sweetened alcohol drinks (5% alcohol), with only one consuming beer and one consuming wine. Four of the males consumed mixed spirits, one mixed spirits and beer and one beer only. Forty per cent of the males had more than seven standard drinks during the study and 67% of the females had more than five drinks.In total, 80% of the subjects had pre-mixed sweetened alcohol drinks at some point during the study period. Forty-three per cent of the subjects reported that they became inebriated and 14. 3% consumed alcohol to the point where they became physically sick. None of the subjects lost consciousness or took recreational drugs during the study period. Comparative CGMS data between study and control periods Results Patients There was no significant difference between the overall mean glucose levels of patients when comparing study and control periods (Table 1; P = 0. 43).Similarly, there were no significant differences in the amount of time spent with either normal or high glucose values between study and control periods (Table 1). A larger proportion of time was spent with low glucose values during the control period when compared with the study period (1. 9 vs. 16. 8%, P = 0. 03). A significantly larger degree of glycaemic variation was seen in the CONGA values in the study period when compared with the control period (Table 1). The difference in CONGA values were consistent and independent of whether glycaemic variation was assessed over 1-, 2- or 4-h intervals.Of the 22 subjects recruited, eight were excluded because their CGMS traces did not have sufficiently frequent calibration points with intermittent capillary measures of blood glucose. Of the 14 subjects remaining, we were able to obtain study period data on 14 patients and matched control period data on only 12 pat ients. The study period occurred on the night prior to the control period in nine subjects.

CONGAn is the standard deviation of different glucose measures n hours apart for the duration of the CGMS trace. of counselling using a harm minimization approach is that the information provided be credible and reflective of ‘real’ or ‘lived’ circumstances.Continuous glucose monitoring provides a technique whereby the glycaemic consequences of various behaviours can be documented in an ambulant or non-artificial setting. Adolescents with Type 1 diabetes frequently consume alcohol in a social context [11]. Alcohol is known to inhibit the gluconeogenic pathway, to inhibit lipolysis, impair glucose counter-regulation and blunt hypoglycaemia awareness [3,4]. Previous studies in young adults with Type 1 diabetes have shown that modera te consumption of alcohol in the evenings without concomitant food intake may cause hypoglycaemia the following morning [5].Consumption of alcohol after a meal, however, has shown no similar adverse effects on glucose [6]. It is reasonable to assume, therefore, that alcohol consumption may be a significant risk factor for hypoglycaemia in adolescents with Type 1 diabetes [5]. Studies of the glycaemic effects of alcohol consumption in an ambulant adolescent/young adult population can be difficult. This is because such behaviours are uncontrolled, often spontaneous and usually in the context of other social activities (parties, dancing, etc. ).In order to ensure that we only reported accurate CGMS data during these activities, capillary blood glucose calibration was considered vital and those patients who failed in this regard were excluded from analysis. Just over 60% of the patients recruited were able to successfully wear and calibrate a CGMS unit during these activities. Given tha t patients who experience hypoglycaemic symptoms are more likely to perform capillary self measures of blood glucose, we feel that it is unlikely that those patients excluded from the analysis had a greater frequency of hypoglycaemia than those patients reported.We were unable to record our subjects’ alcohol consumption in a contemporaneous fashion and hence were reliant upon their recall. It is possible that their remembered patterns of consumption were not entirely accurate. This potential inaccuracy should not be seen as a weakness of this study, as we only set out to determine patterns of glycaemia in adolescents engaging in spontaneous and uncontrolled alcohol consumption. We neither specified the type nor the amount of alcohol to be consumed (our ethical approval was contingent on this not occurring).The data as to amount of alcohol consumed have been included for descriptive purposes only. The results of this study show that alcohol consumption by adolescents in a soci al context is associated with a greater degree of glycaemic variation and less time spent with low glucose values than evenings where no alcohol is consumed. Whilst the second of these findings appears counter-intuitive, there may be several possible explanations. Firstly, the vast majority of our study group ate a meal prior to going out and ate upon their return before going to bed.These are practices that we have instilled as harm minimization strategies to avoid alcohol-induced hypoglycaemia in our clinic. Secondly, most of the alcohol consumed was as pre-mixed spirit and sweetened, carbonated beverages. Finally, alcohol consumption was only associated with vigorous exercise (dancing) in a minority of our study group. All of these factors could have combined to negate the hypoglycaemic effects of alcohol. In a previous study of glycaemia during alcohol consumption in adult men [5], hypoglycaemia occurred most often 10–12 h after wine consumption when the evening before en ded at 23. 0 h. We analysed our data to see if a similar phenomenon occurred in this study and found that the per cent of time spent with CGMS readings < 4 mmol/l between 06. 00 and 12. 00 h on the morning after the study period (i. e. the morning after the drinking night) was only 1. 1%. Notwithstanding the fact that our cohort frequently consumed alcohol later than 23. 00 h, the factors that impacted upon glycaemic control during the study night appear to have carried over to the ‘morning after’. The findings in this study highlight the importance of ambulant testing.It is important to note that the findings of the group studied here may not be seen in adolescents who drink non-sweetened alcoholic drinks or in those adolescents with better underlying metabolic control. Whilst alcohol consumption in isolation may reasonably be thought to cause hypoglycaemia, alcohol consumption by adolescents in the context of meals, sweetened mixers and little activity did not result in more hypoglycaemia than an alcohol-free evening.

Other Voices, Other Rooms †Analysis Essay

Capote’s Other Voices, Other Rooms is an exploration into role reversal, gender definitions, and the risk involved in sexuality and love against the harsh contrast of southern ideals. The novel acts as Capote’s catharsis in developing his younger self, in the character of Joel Knox, innocent and self-exploring, as he transforms into his older, liberated self in the character of Randolph who truly is the voice carrying the books message. However, to reach his destination of Randolph, Joel must begin his journey with Idabel Tompkins. Joel sees Idabel soon after entering Noon City, and is so mesmerized with her boyish antics that he is oblivious to the man offering him a nickle to capture her, something Joel would not be capable of anyway. She notices him later as well, watching Joel in the soda shop from the doorway and asking about him in her†boy-husky† voice. Immediately, Joel is intrigued on the verge of infatuation and most often referencing her boyish attributes in the same breath. On the way to the Landing, his new home, he finds Idabel on the road and picks her out from her sister as, â€Å"[t]he other moved as jerky and quick as a boy† (p31). The pair become friends and later during a fishing trip, Joel learns not only the risks invilved in loving someone but also Idabel’s evaluation of what they are together.. When she tells him to undress so they can swim naked Joel sheepishly replied, â€Å"But you’re a girl† (p131) Idabel, frustrated, replies, â€Å"What you’ve got in your britches is no news to me, and no concern of mine†¦.I never think like I’m a girl; you’ve got to remember that, or we can’t never be friends† later on proclaiming, â€Å"I want so much to be a boy† (p132). During the same trip, Joel felt he needed to put his arms around Idabel as, â€Å"the only means of expressing all he felt† he kisses her cheek and in return she becomes so mad that he pulls his hair and fights him. Joel learns the danger of loving someone, could mean loosing them or being betrayed by them. Idabel comes to get Joel at the Landing, in hopes of picking up a partner in crime to run away with. Joel mistakes this as affection and suggests they  run off and get married, picking grapes to support themselves. Idabel rebukes him sternly, â€Å"I don’t want to get married†¦.Who the hell said I wanted to get married? Now you listen, boy: you behave decent, you behave like we’re brothers, or you don’t behave at all. Anyway, we don’t want to do no sissy thing like pick grapes. I thought maybe we could join the Navy† (p174) on their way to running away, they first stop at the carnival in Noon City where they meet the alluring blonde midget Mrs. Wisteria, a 25 year old carnival worker who also wants to be loved in a society that does not value her. Idabel is immediately smitten with her and Joel notices, to his dismay, â€Å"Idabel, more excited than Joel had ever seen her, rushed up and asked [Miss Wisteria], please, wouldn’t she have some soda pop with them† (p191) Joel Later realizes Idabel is in love with the circus performer. This provokes Joel into a dream where he fears Idabel’s loss and tells her he loves her. He begins to realize he can never have her love. During their conversation, Miss Wisteria talks about her horrible experiences trying to find love and her sorrow that boys must grow tall and therefor, never want her. We see the perfect triangle of unrequited love that can never be fulfilled and can only bring sorrow. Joel longs for Idabel who is in love with the golden curls of Miss Wisteria, who molests Joel while trapped in a ferris wheel in her attempt to find a boy who will never grow tall. In an affirming signal of Joels realization of who he is, Joel sees Randolph, the homosexual transvestite cousin of his step-mother, at the carnival, while being molested by Miss Wisteria. He runs off scared looking for Idabel and hides from Miss Wisteria in the old abandoned house in town. He realizes he has a home and a bed at the Landing with Randolph, while Miss Wisteria is doomed to always be searching rooms for love, as she is now looking for Joel in the old mansion, until she finds her final room, where death awaits. Joel realizes who he is now and is almost comforted by it. He forgets Idabel for most of the rest of the story and assumes she has run off with her circus girl. Joel is content to remain at the Landing, especially after his one connection to the real world is lost when his friend Zoo comes back to stay after a rape has driven her a little crazy as well. He knows he belongs there with Randolph, the ‘ghostly lady’ in the window who wears women’s clothes and wig, but is more like him than whats outside. He hides from his old life in the form of a visit from his  original caretaker, his aunt Ellen, and moves towards Randolph, looking back and leaving his innocent self, the other Joel Knox.
