A Study On Social And Affective Dimensions Of The Use Of Assisted Reproduction Technology (art) By Women In Turkey

Uner, Ozge 01 September 2004 (has links) (PDF)
This thesis aims to discuss the concept of Assisted Reproduction Technology and its social and affective impacts. Women will be at the center of this research as it has been thought that emotional stressors are mostly effective on them. In the present work, an investigation will be carried out among women who have used assisted reproduction technology methods and women who are able to reproduce and conceive &ldquo / naturally&rdquo / . The comparison of these two groups will illuminate problematical aspects of assisted reproduction technology. The research will be based on two sets of questionnaires designed for each group of women. In this study, both qualitative and quantitative data were used. These analyses will not only lead us to compare infertile and fertile women&rsquo / s responses and evaluate the consequences of emergent assisted reproduction technology but also to assess its social and emotional impacts.

Resident Perceptions toward the Social Impacts of a Mega Sport-Event: The case of Fédération Internationale de Basketball (FIBA) EuroBasket 2011 in Vilnius, Lithuania.

January 2011 (has links)
abstract: The purpose of this study was to examine the local residents' perceptions toward the social impacts of FIBA EuroBasket 2011, held September 7th to September 12th, 2011 in Vilnius, Lithuania. This study focuses on the social impacts of the event since most of the mega-event academia is dominated by economic impact studies and this research attempts to go beyond a narrow quantitative approach to examine the social impacts in relation to two important academic contributions: 1) the embracement-withdrawal continuum and 2) the social exchange theory. A mixed methods analysis was adopted as the best approach for this research. Both a quantitative survey and qualitative questionnaire were used which yielded a total usable sample of 128 residents of Vilnius. Exploratory Factor Analysis was conducted to examine the underlying themes of the quantitative data and coding and thematic development was used to make sense of the qualitative data. The results confirmed that the event was considered successful (97% of residents embraced the event) and they generated 6 factors, or impacts, that were deemed important for influencing resident perceptions: social costs, social benefits, sociocultural impacts, socioeconomic impacts, sociopolitical impacts, and socioenvironmental impacts. These results indicate that the use of mixed methods analyses is crucial to investigate the interdependence between each impact that affects residents' perceptions toward sport mega-events. / Dissertation/Thesis / M.S.

Zdravotně - sociální dopady násilí páchaného na dětech a jeho prevence / Health and social impacts of violence against children and its prevention

KLEMENTOVÁ, Zuzana January 2015 (has links)
The diploma thesis deals with health and social impacts of child abuse and its prevention from the perspective of social workers. The theoretical part of the diploma thesis draws on scholarly resources and explains basic terms related to the topic. The first part focuses on violence, victims of violence and abuse in general. The second part describes the CAN syndrome and its history. Moreover, it informs about general attitude towards abuse, maltreatment and neglect in the society. The next chapter concentrates on risk factors of abuse, maltreatment and neglect respectively. The following part addresses health and social impacts of child abuse and the role of social workers when working with child victims of violence. Next, it focuses on legislation that deals with child abuse and services designated to help abused, neglected and maltreated children. The last section of the theoretical part concentrates on child abuse prevention that includes prevention programs and National Strategy on Prevention of Violence against Children in the Czech Republic for the period 2008-2018. The main aim of the thesis was to determine health and social impacts of violence and child abuse prevention from the perspective of a social worker. Next, three following sub-goals were specified: to identify the consequences of child abuse, to determine opinions of social workers on prevention of violence against children and to establish social workers' suggestions for prevention. To fulfill the aforementioned objectives, three research questions were defined: What are the health and social impacts of child abuse from the perspective of social workers? What is the subjective opinion of social workers on child abuse prevention? What are the suggestions and recommendations of social workers for violence prevention? The practical part was conducted by means of qualitative research strategy. The data were collected by a survey method, specifically by a semi-structured interview. The data were analyzed using a clustering method. The research group consisted of five respondents who were selected intentionally. The research group was chosen from the Registry of social services providers. Altogether seven organizations working with abused, maltreated and neglected children were selected. A social worker from each of these seven organizations was contacted. Consequently, five social workers agreed to participate in the research. These social workers were from the Authority of Social and Legal Protection of Children and from other non-governmental organizations. Two other social workers refused to take part in the research. The interviews were always held in the social workers' workplace. The research survey showed that the most common health and social impacts of child abuse are self-harm, mental disorders, identification with the role of a bully and problems in the future relationships. Most respondents stated that prevention of violence against children is sufficient but they added that there is still room for improvement. One respondent said that the level of prevention is inadequate because the process is uncoordinated and coherent methodology as well as continuous approach to children is missing. Furthermore, the research established that the respondents think it is vital to improve child abuse prevention by developing comprehensive methodology and integrating this topic to the school curriculum. All in all, the thesis focuses on a widely discussed topic child abuse is a worldwide up-to-date problem since it occurs very frequently. The purpose of this diploma thesis could be to call attention of the society to child abuse and inform about its occurrence. Next, this thesis could also prove useful in the area of child abuse prevention since it might serve as an information source for experts who deal with prevention of violence against children. It may also motivate people to improve current prevention methods.

No. of bitstreams: 1 5424.pdf: 4133188 bytes, checksum: 0bf3befaace71e6021b526c40f6d3002 (MD5) Previous issue date: 2013-06-17 / Universidade Federal de Minas Gerais / Nanotechnology has been reported as a technology that will have further development in this century and agricultural nanotechnologies gain space with the discovery of its potential applications in the transport of substances, nanosensors, nanocapsules, among others. Many of these nanoproducts are already found in the market or in development, therefore, exposure to nanoparticles concerns the scientific community and policy makers. In this context, this project aims to develop a methodology for assessing the environmental and social impacts of nanotechnology use in agriculture. Given the complexity and scope of nanotechnology, impact indicators were formulated by reviewing specialized scientific literature. The indicators were conceptually validated in a remote consultation with experts of areas related to agricultural nanotechnology through a questionnaire formulated according to the Delphi technique. The Impactos AGNano method has the indicators as an essential basis for its development and has two stages of evaluation: Safety Assessment (preliminary assessment to obtain the Security Index) and Impact Assessment (for obtaining Impact Index). The method was validated in a presential consultation with experts of areas related to nanotechnology in agriculture. / A nanotecnologia tem sido reportada como a tecnologia que terá maior desenvolvimento neste século e as nanotecnologias agrícolas ganham espaço com a descoberta de suas potenciais aplicações no transporte de substâncias, nanossensores, nanocápsulas, entre outros. Muitos destes nanoprodutos já são encontrados no mercado ou em desenvolvimento, dessa forma, a exposição às nanopartículas utilizadas nessas tecnologias preocupa a comunidade científica e os legisladores. Neste contexto, o presente trabalho teve como objetivo a criação de uma metodologia para a avaliação dos impactos ambientais e sociais do uso de nanotecnologias na agricultura. Dada a complexidade e abrangência da área nanotecnológica, indicadores de impacto foram formulados através de revisão de literatura especializada. Os indicadores foram validados conceitualmente em uma consulta remota a especialistas de áreas relacionadas à nanotecnologia agrícola por meio de questionário formulado de acordo com a técnica Delphi. O método Impactos AGNano foi desenvolvido utilizando os indicadores como base e possui duas etapas de avaliação: Avaliação de Segurança (avaliação preliminar para obtenção do Índice de Segurança) e Avaliação de Impacto (para obtenção do Índice de Impacto). O método foi validado em consulta presencial a especialistas de áreas relacionadas a nanotecnologia agrícola.

No. of bitstreams: 1 arquivototal.pdf: 7622757 bytes, checksum: cc3a3fdf41e636a0aefae614f4c8757a (MD5) Previous issue date: 2015-02-20 / The Indigenous Land Potiguara is situated in the north coast of Paraíba, between Camaratuba and Mamanguape rivers, totaling 33,757.00 hectares, of which 1451.20 hectares are overlapping area with the APA of the Mamanguape River Bar, with a population of 19 000 inhabitants. This research aimed to analyze the environmental and social impacts and conflicts after the introduction of shrimp Indigenous Land (TI), from participatory methodology. It can be seen clearly that there are two distinct areas of shrimp farming in the village, one located next to the houses, which have greater influence of non-Indians, increased environmental impacts and are independent families with each other, and another located on the Island of girls with nurseries belonging to the prawn Cooperative Tramataia, only with partners Indians, where there is organization and all pools together belong to all members. According to the Sustainability Framework applied in the two areas, the first has low sustainability, reaching 36.36% positive sustainable responses, while the second reached an average sustainability, reaching 54.55% of positive sustainable questions. So were seen in the first area impacts as mangrove trees cuts, stressed plants, crabs UCAS dead, chemical channels that enter the mangrove, waste coming from the houses and the very exposed activity, in the second area, the worst impact viewed was the proximity of the nurseries with the bank of the estuary of the river Mamanguape. Participatory meeting was organized jointly local wisdom and so was the recognition of all the problems involving the shrimp before an unknown to the Indians. After the technical training person chosen at this meeting, there was the first analysis, independent of outside the village technicians, and through this, the trained Indian identified specific pathology in nursery with early mortality, which was instrumental in making decision and not lost production, avoiding the dead animals were dumped into the estuary. This work is the basis for the implementation of efficient management with dialogue between technical and scientific knowledge and local knowledge and minimize negative impacts, aiming at higher productivity and environmental sustainability. / A Terra Indígena Potiguara está situada no litoral Norte da Paraíba, entre os rios Camaratuba e Mamanguape, totalizando 33.757,00 hectares, dos quais 1.451,20 hectares são área de sobreposição com a APA da Barra do Rio Mamanguape, com uma população de 19 000 habitantes. A presente pesquisa visou analisar os impactos ambientais e sociais e os conflitos após a introdução da carcinicultura na Terra Indígena (TI), a partir de metodologia participativa. Percebe-se nitidamente que existem duas áreas distintas de criação de camarão na aldeia, uma localizada próxima às casas, ao qual tem maior influência de não-índios, maiores impactos ambientais e são de famílias independentes entre si, e uma outra localizada na Ilha das Moças com viveiros pertencentes à Cooperativa de Carcinicultores de Tramataia, somente com índios sócios, onde há organização e todos os viveiros juntos pertencem a todos os cooperados. De acordo com o Quadro de Sustentabilidade aplicado nas duas áreas, a primeira possui baixa sustentabilidade, atingindo 36,36% de respostas sustentáveis positivas, já a segunda atingiu sustentabilidade média, chegando a 54,55% de perguntas sustentáveis positivas. Assim, foram vistos na primeira área impactos como cortes de árvores de mangues, plantas estressadas, caranguejos-uçás mortos, químicos em canais que adentram o manguezal, lixos oriundos das casas e da própria atividade expostos, já na segunda área, o pior impacto visualizado foi a proximidade dos viveiros com a margem do estuário do rio Mamanguape. Na reunião participativa organizou-se conjuntamente a sabedoria local e assim ocorreu o reconhecimento de todos os problemas que envolviam a carcinicultura, antes uma incógnita para os indígenas. Após o treinamento técnico com pessoa escolhida nesta reunião, realizou-se a primeira análise, independente de técnicos de fora da aldeia, e através desta, a índia treinada identificou patologia específica em viveiro com início de mortalidade, o que foi providencial para a tomada de decisão e não se perdeu a produção, evitando-se que os animais mortos fossem despejados no estuário.Este trabalho serve de base para a implementação de manejo eficiente com diálogo entre conhecimento técnico-científico e conhecimento local e minimização dos impactos negativos, visando uma maior produtividade e sustentabilidade ambiental.

Regarding the Amazon, there is much to discuss and improve the scope of projects for large hydroelectric plants, built for a generating energy, but because involve forced displacement of populations due to the dams of the rivers, often have large social conflicts created as occurred historically, from projects and military government agencies, in the 1960, 1970 and 1980 in Brazil. One of Amazonian dams that showed great potential for the generation of these conflicts was Balbina. Located in Presidente Figueiredo, in the Central Amazon, the Balbina dam had completed its construction in 1987, flooding an area of 2.400 km2 of forest, reaching about 3.000 families living downstream of the dam. The objective of this study is to analyze social impacts after nearly 25 years of operation of the dam began in 1989. The impacts were analyzed based on: i) participant observation, in which the social context is described, and ii) study and inferential analysis of lifestyles, through analytic ethnography. At around Balbina were interpreted results indicating disaffiliation territorial biases and emotional, fragmentation of belonging, weakening of social relations and demotion of practical actions for the formation of organized groups in the region. How coping and mitigating actions, we chose to highlight: i) suspension and cancellation, immediately, via action by Public Ministry and Procon, of all debts pertaining to electricity bills that have been imputed to those affected by dams, ii ) reorganization of the economy within the living environments to address food insecurity and lack of income, iii) implementation of a model of trade with use aggregate of social currency to those affected by the dam and iv) the orientation of production according to the population diversity upstream and downstream of the dam. / O desenvolvimento sustentável é uma necessidade global. No que tange à Amazônia, há muito o que se debater e melhorar no âmbito dos projetos para grandes centrais hidrelétricas, construídas para a geração energética, mas que, dado implicarem deslocamentos forçados de populações por causa das barragens dos rios, amiúde tem criado amplos conflitos sociais em épocas atuais, tal como ocorreu historicamente, a partir de projetos de organismos e governos militares, nas décadas de 1960, 1970 e 1980 no Brasil. Uma das represas amazônicas que apresentou grande potencial para a geração desses conflitos foi Balbina. Localizada em Presidente Figueiredo, na Amazônia Central, a represa de Balbina teve finalizada sua construção em 1987, alagando uma área de 2.400 km2 de floresta, atingindo cerca de 3 mil famílias que viviam a jusante e montante da usina. O objetivo do presente trabalho foi analisar impactos sociais após duas décadas e meia de operação da hidrelétrica, iniciada em 1989. Os impactos foram analisados a partir de: i) observação participante, em que o contexto social é descrito; e ii) estudo e análise inferencial dos modos de vida, por meio da etnografia analítica. No entorno de Balbina, foram interpretados resultados de vieses de desfiliação territorial e afetiva, fragmentação de pertencimento, enfraquecimento de relações sociais e rebaixamento de ações práticas para a formação de grupos organizados na região. Como ações de enfrentamento e mitigadoras, optou-se por destacar: i) suspensão e cancelamento imediado, via ação judicial, dos passivos financeiros que tenham sido imputadas aos atingidos pela UHE Balbina, ii) reorganização da economia dentro dos ambientes de vivência para enfrentar a insegurança alimentar e a falta de renda, iii) implantação de um modelo de comércio agregador com uso de moeda social para os atingidos pela barragem e iv) a orientação da produção segundo a diversidade populacional a montante e jusante da represa.

FundaÃÃo de Amparo à Pesquisa do Estado do Cearà / The riverside and marine plains of Cearà state have been occupied in the last 10 years by the marine shrimp culture that has generated social and environmental impacts over these areas. Recently, new areas of these plains in Cearà have been target of the expansion of shrimp farms, especially in Aracati municipality. It is seen that marine shrimp culture is an activity surrounded by matters that sometimes justify the activity moratorium defended by ambientalists, sometimes justify its implementation by the producers, as marine shrimp culture, as other economical activities, generates both negative and positive impacts over the places where it is inserted. By this meaning it becomes necessary to identify the social impacts, as the environmental impacts promoted over the areas of influence of the agro business of marine shrimp culture, from the studied areas, on Aracati municipality on Cearà state, proposing actions that can minimize the negative impacts and reinforce the positive impacts. To do so, researches were realized on the bibliographical sources of the public organs libraries in Fortaleza; visits to various organs that maintain direct relationships with the activity in Aracati municipality, as works on the study field. The marine shrimp culture is an activity of great importance to Aracati municipality because of its direct and indirect generation of work positions. Although, it can be seen that the activity in Aracati is spacely unorganized, generating conflicts against the estuarial environment and other economical activities, as carnauba straw handcraft and fishing on the marsh. The economic-ecological zoning for the activity in matter in Aracati municipality is the correct direction to minimize the negative environmental and social impacts and reinforce the positive impacts promoted by the implementation of marine shrimp culture. / As planÃcies flÃvio-marinhas do Estado do Cearà vÃm sendo ocupadas nos Ãltimos 10 anos pela carcinicultura marinha que tÃm gerado impactos sociais e ambientais. Recentemente novos espaÃos dessas planÃcies no Cearà foram alvo da expansÃo das fazendas de camarÃo, principalmente no MunicÃpio de Aracati. Observa-se que a carcinicultura marinha à uma atividade cercada por questÃes que ora justificam a moratÃria da atividade defendida por ambientalistas, ora justificam a implementaÃÃo da mesma pelos produtores, pois a carcinicultura, assim como outras atividades econÃmicas, gera impactos negativos e positivos nos locais em que se insere. Neste sentido faz-se necessÃrio identificar os impactos sociais assim como os impactos ambientais promovidos nos espaÃos de influÃncia do agronegÃcio da carcinicultura marinha, a partir das Ãreas estudadas, no MunicÃpio de Aracati no Estado do CearÃ, propondo aÃÃes que possam minimizar os impactos negativos e reforÃar os impactos positivos. Para tanto foram realizadas pesquisas nos acervos bibliogrÃficos das bibliotecas de ÃrgÃos pÃblicos em Fortaleza; visitas a vÃrios ÃrgÃos que mantÃm relaÃÃes diretas com a atividade no MunicÃpio de Aracati, assim como trabalhos de campo na Ãrea de estudo. A carcinicultura à uma atividade de suma importÃncia para a economia do MunicÃpio de Aracati em funÃÃo da geraÃÃo direta e indireta de postos de trabalho. Observa-se, porÃm que a atividade em Aracati à desorganizada espacialmente, gerando conflitos com o ambiente estuarino e com outras atividades econÃmicas como o artesanato da palha de carnaÃba e a pesca no manguezal. O Zoneamento EconÃmico-ecolÃgico para a atividade em questÃo no MunicÃpio de Aracati à a direÃÃo correta para que sejam minimizados os impactos ambientais e sociais negativos e reforÃados os impactos positivos promovidos com a implementaÃÃo da carcinicultura.

These cold air masses of polar origin, locally known as friagens, cause sudden drops in air temperature. In this study we analyzed 14 cases of chills occurred in the state of Amazonas during the period 2000 to 2010 with minimum temperature, the National Institute of Meteorology. Data from the numerical model (NCEP / NCAR) were used to simulate the dynamic and synoptic conditions leading event in July 2010, the most intense period of study, which showed temperatures of 11.8 ° C in the southwest of the state and 16 ° C in Iuauretê, as in the northern hemisphe re. The population of students from the cities of southwestern Amazon, mostly suffers no adverse impacts to the incursions of cold air. However, from analysis of data from the state Department of Rural Production (Sepror), it appears that fish production can be seriously affected events with intense cold, falling production, causing losses to fish farmers and thus for the Amazonas economy . / O estado do Amazonas é atingido anualmente pelas incursões de ar frio durante inverno austral. Essas massas de ar frio de origem polar, localmente conhecidas por friagens, ocasionam quedas bruscas de temperatura do ar. No presente trabalho foram analisados os 14 casos de friagem ocorridos no Estado do Amazonas durante o período de 2000 a 2010 com dados de temperatura mínima do Instituto Nacional de Meteorologia. Dados do modelo numérico (NCEP/NCAR) foram utilizados para fazer a simulação das condições sinóticas e dinâmicas que antecederam evento de Julho de 2010, o mais intenso do período estudado, que apresentou temperaturas de 11.8°C no sudoeste do estado e 16°C em Iuauretê, já no hemisfério norte. A população dos estudantes das cidades dos sudoeste do Amazonas, em sua maioria, não sofre impactos negativos com as incursões de ar frio. Porém, a partir da análise de dados da Secretaria Estadual de Produção Rural (SEPROR), verifica-se que a produção de peixes pode ser seriamente afetada com eventos intensos de friagem, caindo a produção, gerando prejuízos para piscicultores e consequentemente para a economia do Amazonas.

Práticas de governança corporativa em empresas brasileiras e impactos socioambientais / Corporate governance practices at the Brazilian companies and socio-environmental impacts

Flavia Kao 04 May 2017 (has links)
Esta pesquisa objetiva entender como as práticas de governança corporativa (GC) adotadas por empresas industriais brasileiras relacionam-se com os impactos socioambientais de suas operações. Para atingir o objetivo principal foram formulados os seguintes objetivos específicos: 1) apresentar as características da amostra em termos de setor de atuação, adoção de práticas de GC e níveis de impactos ambientais e sociais; 2) conhecer as associações existentes entre os impactos ambientais, sociais e práticas de GC adotadas pelas empresas brasileiras; 3) verificar se tais associações são influenciadas pelo setor de atuação. A fundamentação teórica aborda as perspectivas teóricas que embasam a relação entre GC e sustentabilidade, os aspectos gerais envolvendo a sustentabilidade e específicos sobre gestão socioambiental, os aspectos gerais sobre o sistema de governança corporativa e aspectos específicos sobre as boas práticas de GC no Brasil, finalizando com as pesquisas nacionais e internacionais que investigaram esse relacionamento. A amostra pesquisada é composta por 46 empresas brasileiras listadas na BM&FBovespa e com dados disponíveis na base de dados ®ASSET4, da Thompson Reuters(TM), de 2010 a 2014. Os níveis de impacto tanto ambiental como social foram determinados em função da posição da empresa em relação às demais componentes da amostra em termos dos seus resultados nas oito variáveis selecionadas, resultando em três categorias: Alto, Médio e Baixo Impacto Social e Ambiental. Analogamente, o nível de adoção às práticas de GC foi determinado em função da posição da empresa em relação às demais em termos de seus resultados em sete variáveis selecionadas. As técnicas empregadas nesta pesquisa, de natureza quantitativa, compreenderam análises descritivas para a apresentação das características da amostra, Teste Qui-quadrado para a identificação das associações existentes entre as práticas de GC e os impactos socioambientais e Análises de Correspondência Múltipla para identificar a influência do setor de atuação sobre tais associações. Os resultados indicam maiores níveis de associação entre a dimensão social e as práticas de GC, comparativamente à dimensão ambiental, embora em ambos os casos tenham sido verificadas associações tanto positivas como negativas. Ademais, a hipótese de que tais associações são influenciadas pelo setor de atuação foi confirmada em ambas as dimensões, indicando, inclusive, que o baixo nível de adoção às práticas de GC ocorre entre em setores de alto impacto tanto ambiental como social. Desta forma, este estudo busca contribuir apresentando evidências de associação entre práticas de GC e impactos socioambientais no contexto brasileiro, possibilitando avançar na busca por conhecimento sobre como o sistema de GC pode contribuir para o alcance de negócios mais sustentáveis e alinhados aos objetivos da sustentabilidade. / This research aims to understand how the corporate governance (CG) practices adopted by Brazilian industrial companies are related to the socio-environmental impacts of their operations. In order to achieve the main objective, the following specific objectives were formulated: 1) to present the characteristics of the sample in terms of activity sector, adoption of CG practices and levels of environmental and social impacts; 2) to know the existing relationships among the environmental, social and CG practices adopted by Brazilian companies; 3) to verify if such combinations are influenced by the sector of performance. Theoretical fundamentals address the theoretical perspectives that support the relationship between CG and sustainability, the general aspects of sustainability and specific aspects of social and environmental management, the general aspects of the corporate governance system and specific aspects of CG practices in Brazil, ending up with national and international surveys that investigated this relationship. The sample surveyed is composed by 46 Brazilian companies listed on the BM&FBovespa, as well as with data available in Thompson Reuters(TM) database ®ASSET4 between 2010 and 2014. The levels of environmental and social impact were determined based on the company\'s position in relation to the other components of the sample in terms of their results within the eight selected variables, resulting in three categories: High, Medium and Low Social and Environmental Impact. Similarly, the level of adoption of CG practices was determined according to the company\'s position in relation to the others in terms of results in seven selected variables. The techniques used at this quantitative nature research have included descriptive analyzes for the presentation of the characteristics of the sample, Qui-square Test for the identification of the relationships among CG practices, social and environmental impacts and Multiple Correspondence Analysis to identify the influence of the activity sector on such associations. The results indicate higher levels of association between the social dimension and CG practices, compared to the environmental dimension, althought in both the cases positives and negatives associations were identified. In addition, the hypothesis that the associations are influenced by the sector of activity was confirmed in both dimensions, indicating that low levels of adoption of CG occurs between sectors with high environmental and social impact. Thus, this study seeks to contribute by presenting evidence of association between practices and socio-environmental impacts at the Brazilian context, allowing to advance in the search of knowledge on how the CG system can contributed to the achievement of a more sustainable development business and aligned with the objectives of sustainability.
