The Conceptualization of Genocide in the International Media: A Case Study of Darfur

Costello, Kayla 01 May 2009 (has links)
Cross-national crime studies are often plagued with conceptualization issues. In specific, some countries may define certain acts of violence as crimes, whereas others may perceive these acts as justifiable or culturally prescribed. This difference in conceptualization is especially the case with the crime of genocide, which the Convention on the Prevention and Punishment of the Crime of Genocide of 1948 defines “as any of a number of acts committed with the intent to destroy, in whole or in part, a national, ethnic, racial or religious group.” Despite this legal definition, countries, organizations, institutions or individuals may label a crisis as genocide, civil war, or another type of conflict. Because the printed mainstream media reflects and shapes the public perception of international conflicts, this research employs content analysis and quantitative methodology in examining published accounts of the conflict in the Darfur region of Sudan over the last five years. Using articles from newspapers in the United States, Great Britain, China, and Qatar, I examined the extent to which the term genocide is used to illustrate this conflict within the mainstream media from these four different countries. The results of this study suggest that the geographic location of a news outlet does not necessarily play a role in the conceptualization of genocide. The most important factors in this process are the way in which the author of the article frames the conflict, whether the author chooses to use quotes from certain organizational leaders, and the context in which the term genocide is used when it is chosen in favor of the term ethnic cleansing or civil war. These findings imply that news sources play a large role in public perception of genocide.

Prioritized Exploration Strategy Based On Invasion Percolation Guidance

Karahan, Murat 01 January 2010 (has links) (PDF)
The major aim in search and rescue using mobile robots is to reach trapped survivors and to support rescue operations through the disaster environments. Our motivation is based on the fact that a search and rescue (SAR) robot can navigate within and penetrate a disaster area only if the area in question possesses connected voids Traversability or penetrability of a disaster area is a primary factor that guides the navigation of a search and rescue (SAR) robot, since it is highly desirable that the robot, without hitting a dead end or getting stuck, keeps its mobility for its primary task of reconnaissance and mapping when searching the highly unstructured environment We propose two novel guided prioritized exploration system: 1) percolation guided methodology where a percolator estimates the existence of connected voids in the upcoming yet unexplored region ahead of the robot so as to increase the efficiency of reconnaissance operation by the superior ability of the percolation guidance in speedy coverage of the area / 2) the hybrid exploration methodology that makes the percolation guided exploration collaborate with entropy based SLAM under a switching control dependent on either priority given to position accuracy or to map accuracy This second methodology has proven to combine the superiority of both methods so that the active SLAM becomes speedy, with high coverage rate of the area as well as accurate in localization.

Perceptions of Empty Nest Mothers From Diverse Socioeconomic Backgrounds With Boomerang Kids

Lary, Banning Kent 01 January 2015 (has links)
In the United States, a growing number of young people are failing to launch into self-sufficiency, a characteristic of adulthood recognized by most cultural groups. These â??boomerang childrenâ?? return home and interrupt the life course development of their â??empty nestâ?? mothers who must suspend plans for self-development. How mothers from different socioeconomic backgrounds cope with this countertransitional phenomenon while preparing their children for successful relaunch is not well known. Elder's life course paradigm provided the theoretical framework for this phenomenological study. Perceptions were collected from an ethnically diverse group of 23 empty nest mothers with 30 boomerang children and seven boomerang grandchildren from five U.S. states, recruited using criterion-based convenience sample. Data were collected through recorded telephone interviews that were transcribed verbatim, and analyzed using Saldana's codes-categories-emergent themes model. The findings revealed that boomerang children caused emotional and financial distress, a reassessment of parenting skills, and that boomerang grandchildren reinvigorated the mother's prime identity as a caregiver. These findings were consistent regardless of ethnicity or socioeconomic status. This study contributes to the empirical literature by depicting the boomerang phenomenon as a shift in cultural expectations which represents a new phase in the life course development paradigm. Findings from this study can also guide the work of future researchers, assist mental health counselors who deal with these issues, and inform school guidance counselors who design career trajectories for students.

Compassion Fatigue and Crisis Workers' Attitude to Work

Loolo, Maria Adneza 01 January 2016 (has links)
Past research has revealed that mental health practitioners experience challenging reactions in the course of their professional interactions with traumatized clients in the clinical work setting. The demands of caring, without commensurate replenishment, deplete the practitioners' empathy and produces forms of apathy and indifference towards the suffering of others, known as compassion fatigue. This quantitative, exploratory, cross sectional study examined the predictive relationships between compassion fatigue and work attitudes in primary care physicians located in West Africa. The etiological model of compassion fatigue and constructivist self-development theory (CSDT) formed the conceptual framework for examining clinician responses to trauma-related experiences in the clinical work environment. The main research question in this study was: How well does the level of compassion fatigue in practitioners predict their work attitudes in the clinical work setting? Survey data collected from 67 primary care physicians were analyzed using a linear regression modeling procedure. Results showed that practitioners' compassion fatigue was a statistically significant predictor of their work attitudes, F(1,65) = 7.78, p < .05, R² = .107. Results also confirmed that compassion satisfaction moderated the effect of compassion fatigue in practitioners. The data revealed that higher levels of compassion satisfaction was related to more positive levels of attitudes toward work. This study provided empirical information regarding the predictive relationships between compassion fatigue, compassion satisfaction, and work attitudes. The results can be used to promote social change by providing health-care leaders in developing countries information that supports the need for activities, services, and support programs that enhance compassion satisfaction in physicians, to improve work attitudes. Such programs would promote further social change by improving the physicians' well-being, and mitigating the effects of compassion fatigue.

Innovative energy harvesting technology for wireless bridge monitoring systems

Weaver, Jason Michael 26 October 2011 (has links)
Energy harvesting is a promising and evolving field of research capable of supplying power to systems in a broad range of applications. In particular, the ability to gather energy directly from the environment without human intervention makes energy harvesting an excellent option for powering autonomous sensors in remote or hazardous locations. This dissertation examines the possibility of using energy harvesting in new and innovative ways to power wireless sensor nodes placed in the substructures of highway bridges for structural health monitoring. Estimates for power requirements are established, using a wireless sensor node from National Instruments as an example system. Available power in a bridge environment is calculated for different energy sources, including solar radiation, wind, and vibration from traffic. Feasibility of using energy harvesting in such an application is addressed for both power availability and cost as compared with grid power or primary batteries. An in-depth functional analysis of existing energy-harvesting systems is also presented, with insights into where innovation would be most beneficial in future systems. Finally, the development of a suite of complementary energy-harvesting devices is described. Because conditions on bridges may vary, multiple solutions involving different energy domains are desired, with the end user able to select the harvester most appropriate for the specific installation. Concept generation techniques such as mind-mapping and 6-3-5 (C-Sketch) are used to produce a wide variety of concepts, from which several promising concept variants are selected. The continued development for one concept, which harvests vibration using piezoelectric materials, is described. Analytical modeling is presented for static and dynamic loading, as well as predicted power generation. Two proof-of-concept prototypes are built and tested in laboratory conditions. Through the development of this prototype, it is shown that the example wireless sensor node can successfully be powered through energy harvesting, and insights are shared concerning the situations where this and other energy harvesters would be most appropriate. / text

Korupcijos socialinės ir teisinės apibrėžties įtaka korupcinių veikų tyrimo metodikų koncepcijos pokyčiams / The influence of social and legal definition of corruption on the changes of conception of investigation methodologies of corruption – related crimes

Šatienė, Gintarė 20 January 2009 (has links)
Disertacinio darbo temos aktualumas. Statistiniai duomenys, leidžiantys teigti, kad korupcinių veikų mastas Lietuvoje mažas, prieštarauja sociologinių tyrimų rezultatams, anot kurių, korupcijos faktų Lietuvoje yra labai daug , kas reikalauja šio reiškinio mokslinės analizės. Temos aktualumą grindžia ir korupcijos reiškiniui būdingas latentiškumas, šio reiškinio dinamika, formų, pasireiškimo sričių, subjektų, dalyko kaita, be to, tikslios ir aiškios korupcijos sąvokos, kurią būtų lengviau taikyti teisėkūroje, viešojo administravimo institucijų praktikoje, ją geriau suvoktų visuomenė, lengviau būtų deramai taikyti antikorupcinius įstatymus, stoka. Atsižvelgiant į tai, kad formuojant teisinės sistemos modelį, svarbiausios yra teisės sampratos, teisės doktrinos problemos, disertacijoje pabrėžiama, kad, visų pirma, kuriant nacionalinę antikorupcinių įstatymų bazę ir teisės normose apibrėžiant korupcines veikas, negalima apsiriboti vien tik teisės aktų keitimu kitais, o būtina išsiaiškinti žmonių teisinio mąstymo principus, visuomenės vertybių sistemą ir kriterijus, ir tik po to pereiti prie socialinių reiškinių objektyvizacijos ribų nustatymo teisės normose ir jų įgyvendinimo. Atitinkamai disertacijos įvade konstatuojama, kad efektyvinant korupcinio pobūdžio nusikalstamų veikų tyrimą, ypatingas dėmesys turi būti skiriamas kriminalistikos mokslui, nes suvokimas, jog korupcija yra sudėtinga socialinė, ekonominė, politinė, teisinė, kultūrinė, moralinė problema, kurią reikia spręsti... [toliau žr. visą tekstą] / The Relevance of the Topic of the Dissertation Work. The statistical data allowing stating that the extent of corruption acts is small in Lithuania disagree with the results of the sociology researches according to which there are a lot of facts of corruption in Lithuania , what requires the scientific analysis of this phenomenon. The relevance of the topic is grounded by the latency which is characteristic to corruption, dynamics of this phenomenon, the change of the forms, manifestation spheres and the subject, besides, the lack of the adequate and lucid concept of corruption which could be easier applied in the legislation and the practice of the institutions of public administration, and which could be easier perceived by the society and it would be easier to apply properly anti-corruption laws. In respect that when forming the model of the legal system, the most important are the law concepts, the problems of law doctrine, it is emphasized in the dissertation that, first of all, when creating the national base of the anti-corruption laws and determining the corruption acts in the rules of law, we should not restrict ourselves only to the change of legal acts, but it is necessary to find out the principles of people’s legal thinking, the value system and the criteria of the society, and only then pass on to the determination of the materialization limits of social phenomena in the rules of law and their implementation. Respectively, it is stated in the introduction of... [to full text]

Food Stories: A Labrador Inuit-Metis Community Speaks about Global Change

Martin, Debbie Holly 09 December 2009 (has links)
Background: Food nourishes us, sustains us, and has the potential to both heal us and make us sick. Among many Indigenous cultures, traditional activities, ceremonies, events and practices often involve or use food, grounding Indigenous peoples within the context of their local, natural surroundings. This suggests that food is important not only for physical health, but also emotional, mental and spiritual health. The relationships that Indigenous peoples have with food can help us to understand the health of individuals, and the communities in which they live. Purpose: The following qualitative study explores how three generations of adults who live in one Labrador Inuit-Metis community experience and understand their relationships to food in a context of global change. Theoretical Orientation: The research is guided by Two-Eyed Seeing. Two-Eyed Seeing acknowledges that there are many different ways of seeing and understanding the world, some of which can be encompassed through a ‘Western eye’ and some through an ‘Indigenous eye.’ If we learn to see through both eyes, we can gain a perspective that looks very different than if we only view the world through a single lens. Methods: For the study, twenty-four people from the south-eastern Labrador community of St. Lewis participated in individual and joint story-telling sessions. A group story-telling session also took place where community members could share their stories with one another. During many of the story-telling sessions, participants shared photographs, which helped to illustrate their relationships to food. Findings/Discussion: Historically, the people of St. Lewis relied almost entirely upon their own wherewithal for food, with few, if any, government services available and very little assistance from the market economy. This fostered and upheld an Inuit-Metis culture that promoted sharing, reciprocity and respect for the natural world. Currently, greater access to government services and the market economy has led to the creation of certain policies and programs that undermine or ignore established social and cultural norms in the community. Conclusions: Existing Inuit-Metis knowledge should work alongside non-Indigenous approaches to policy and program development. This would serve to protect and promote the health of both individuals and communities.

Local Ghanaian Stakeholder Perceptions After One Year of a New School Feeding Program in Adjeikrom, Ghana

Fowler, Monica E 01 January 2012 (has links)
The objective of this qualitative longitudinal study was to assess stakeholder perceptions after one year of a new school feeding program to contrast and compare to pre-program expectations. Semi-structured interviews were conducted using questions reviewed by an in-country collaborator for cultural sensitivity and appropriateness. Follow up questions were determined from participant response. The interviews were analyzed by performing content analysis using open and axial coding to find key concepts in the data. The results showed the school feeding program met stakeholder expectations regarding reduction in absenteeism and truancy, improving classroom behavior and increasing enrollment as well as relieving short term hunger. The stakeholders also reported unexpected improvements in behavior of the child at home, increased disposable income, and extra meals being served at home.

The relationship between systems development methodologies and Information Technology project success / Maphisa Shirley Nkone

Nkone, Maphisa Shirley January 2013 (has links)
The purpose of this study was to investigate the relationship between systems development methodologies (SDMs) and the success of Information Technology (IT) projects. The study also seeks to find other critical success factors (CSFs) that influence IT projects success. What initiated this study, with reference to the literature review, is the apparent general view that IT project deliveries are still late, over budget, and unpredictable (Chow & Cao, 2008:961; The Standish Group, 2004). To some extent, the entire project fails before delivering an application. Hence this causes the need to investigate the employment of SDMs and their belief that SDMs improve quality in the development of IT projects and permit more flexible deployment to IT projects (Idea Group Publishing, 2006:13; Dyba et al., 2005:447; Mihailescu & Mihailescu, 2009:1). However, SDMs are still less popularly used (Siau & Tan, 2005:3132; Masrek I., 2008:137). The study provides insight into the relationship between SDMs and the IT projects. A survey using a questionnaire was carried out to obtain the data. The study employed a positivist paradigm and used a quantitative approach. A total of 132 questionnaires were returned from systems developers, IT project managers and team leaders from system development companies. It was found that there is a relationship between systems development methodologies (SDMs) and IT project success. Despite recognizing the benefits and advantages of using SDMs, some respondents disclosed that they were not inclined to employ SDMs and the popular reason was that their profile of development projects didn‟t require the use of SDMs. Multiple regression analysis was used to determine the relationship. Consequently, the top ten CSFs were observed and it was found that “identifying potential risk” and “opportunity” were the most favourable factors. The study could have obtained richer and more insightful information regarding SDMs and critical success factors if more data had been collected. Future work should seek to determine the risks, challenges and problems associated with the adoption of SDMs. / MSc (Computer Science), North-West University, Potchefstroom Campus, 2013
