Excerpt: The study by Lee and Jung (2012) recently published in Workplace Health and Safety concluded that, “A collective effort is needed on the parts of employers, employees, occupational health nurses, and the government to protect working women from lifting heavy items while pregnant” (p. 25). However, that conclusion over-reaches their data and consequently is not supported. First, inconsistencies existed in the odds ratios (ORs), indicating uncertainties in the stability of the statistical findings. Second, the study used a nonexperimental design with low internal validity, preventing conclusions about causation due to the possibility of external intervening variables.

Thesis advisor: Philip E. Strahan / The essays on the gender gap in entrepreneurship examine the trade-offs between women's family formation choices and career aspirations in the setting of small businesses and entrepreneurship. The first essay titled ``Family Comes First: Reproductive Health and the Gender Gap in Entrepreneurship,'' uses Census data to show how better access to reproductive care increases women's propensity to become entrepreneurs, correlates positively with female entrepreneurial activity, and negatively with female entrepreneurial age. Examining firm size and personal income suggests it also improves the success of female-led businesses. Finally, it shows how policies securing better reproductive care enable more women to become entrepreneurs and, potentially, drive economic growth. The second essay titled ``Reproductive Rights and Women's Access to Capital,'' explores the impact of reproductive care restrictions on female entrepreneurs seeking to raise capital. It tests the hypothesis that better access to reproductive care enables women to plan their family formation better, avoid unexpected pregnancies, and gain access to cheaper capital as a result of this reduced risk. This hypothesis is analyzed using restricted data from the National Longitudinal Survey of Youth (NLSY79) in a difference-in-differences setting around the enactment of state-level legislation limiting access to reproductive care. It finds restrictions on reproductive care to be detrimental to women seeking to raise capital and open their own firms. Women who have limited reproductive care access are less likely to borrow, end up taking smaller loan amounts, and have lower leverage ratios. The main contribution of the first essay is that it establishes a direction and causal relationship between reproductive care and entrepreneurship, and of the second essay is that it shows how the increased risk of unplanned pregnancy translates into reduced credit availability for female entrepreneurs at childbearing age. / Thesis (PhD) — Boston College, 2021. / Submitted to: Boston College.

The objective of this diploma thesis is the analysis and comparison of abortion in selected countries of Central Europe - Czech republic, Slovakia, Poland and Hungary. In the thesis is analyzed in detail the controversial topic of abortions in terms of the various factors that affect it. For a detailed comparison of the differences between countries are used the indicators of abortion and direct method of standardization, through which is possible to compare the countries and eliminate the influance of age structure. The analysis showed that even though it is the neighboring countries of Central Europe, the situation regarding abortions is significantly different, especiall due to legislative changes and other important factors.

The purpose of the study was to explore and describe factors influencing termination of pregnancy and describe measures that can be implemented to reduce the high rate of Termination of pregnancy (TOP). A qualitative, exploratory, descriptive and contextual research design was followed, in order to explore and describe factors influencing termination of pregnancy in Mafikeng North West Province. Purposive sampling was utilized to identify participants who met inclusion criteria for the study. The sample size was determined by data saturation, which was reached after twenty five in-depth individual interviews with women requesting TOP was done. In-depth individual interviews were utilized to gather data after written approval from the Human research Ethics committee as well as the Research Ethics Committee of the North West University (Mafikeng Campus), North West Provincial Department of Health, Operational manager of Montshioa Stadt Health Centre, and Hospital Manager of Mafikeng Provincial Hospital where data was collected, and consent was also obtained from women who requested TOP. The findings of this study indicated that factors influencing termination of pregnancy were economic factors, the need for self development, health factors and social factors. From the results, women requesting termination of Pregnancy think that effective use of contraceptives and correct use of condom can reduce the high rate of termination of pregnancy. Conclusion reached were that, non-use of contraceptives and incorrect use of condoms influenced TOP, as it was their common problem, hence the researcher suggested that health education on different methods of contraceptives should be given to teenage girls and other older women by health care providers. Recommendations in the field of nursing practice, nursing education, as well as nursing research were made. / Thesis (M.Cur) North-West University, Mafikeng Campus, 2012

From the clinical situation, the development of this work led us built some directions to think of the metapsychology of portability/sustenance of a child. The text unfolds in six chapters. The first chapter is dedicated to consider the relations among clinical method, research on Fundamental Psychopathology and the paths that the author had gone through since her encounter with motherhood, and its clinic. The second chapter opens a dialogue between evolutionary biology and Fundamental Psychopathology, emphasizing human subject´s singularity and its mythical constructions. The third and fourth chapters seek to a bibliographic review of the phenomena treated, in other fields of knowledge, overcoming speeches that recur and do not effectively support explanations of these phenomena. The clinical case composes the fifth chapter of this work. Through it, we were led to raise some interrogations and reflect on the relation between (in)fertility manifested in body and life and the psychic plot of a psychopathological subject. In such a manner, we were encouraged to think and to highlight the tenuous relationships that are established in the field of procreation between nature and culture, especially on sixth chapter. For this, we turned to the myths and the evidences that are also present in an institution called maternity / Esta tese, desenvolvido na perspectiva da psicopatologia fundamental e da psicanálise, tem como objetivo apresentar algumas reflexões acerca das (in)fertilidades e dos abortamentos espontâneos, especialmente sem causas determinadas, a partir de desdobramentos de uma trabalho clínico com mulheres que vivenciaram tais fenômenos. O desenvolvimento da mesma levou-nos, a partir da situação clínica, a construir algumas direções para se pensar na metapsicologia da portação/sustentação de um filho. O texto desdobra-se em seis capítulos. O primeiro dedica-se a traçar considerações acerca do método clínico, da pesquisa em psicopatologia fundamental e os caminhos trilhados pela autora desde o seu encontro com a clínica da maternidade. O segundo abre uma interlocução entre a biologia evolutiva e a psicopatologia fundamental, enfatizando a singularidade do sujeito humano e as suas construções míticas. O terceiro e quarto capítulos buscam fazer uma revisão bibliográfica sobre os fenômenos tratados, recorrendo inclusive a diversos campos de saber. Ultrapassar discursos que se repetem e não sustentam de forma efetiva explicações acerca dos fenômenos estudados. O caso clínico compõe o quinto capítulo deste trabalho. Através dele, fomos conduzidos a levantar várias questões e refletir acerca da relação existente entre infertilidades que se manifestam no corpo e na vida e a trama psíquica do sujeito psicopatológico. Foi assim que fomos instigados a pensar e ressaltar as tênues relações que se estabelecem no campo da procriação entre natureza e cultura, especialmente no sexto capítulo. Para isso, recorremos aos mitos e as evidências que também se apresentam nas instituições hospitalares chamadas maternidades

Presents in its life cycle, intermediate hosts between they are the goats, and definitive hosts represented by the canids. The study was conducted in the state of Rio Grande do Norte in partnership with Brazilian Company of Agricultural Research. Were visited and surveyed two Mesoregions producing (Central and West), with aim of perform epidemiological study of antibodies anti-N. caninum, questionnaires were applied to characterization zoosanitary, beyond of blood collection to obtain serum. The sera were stored at -20°C until analysis at Embrapa Beef Cattle. Serum samples were subjected to indirect immunofluorescence (IFAT ≥ 1:50) and evaluated using univariate and multivariate analysis for verification of risk factors. The serological results demonstrated high presence of antibodies anti-N. caninum, with prevalence of 36.5% ranging from zero to 100% between the properties studied. Among the risk factors, the system of creation presented a highest correlation with the agent, followed by water source and presence of wild dogs in the facilities, directly influencing the presence of protozoan in goat herd of Rio Grande do Norte / A neosporose é uma doença causada pelo protozoário Neospora caninum, que possui ampla variedade de hospedeiros promovendo alterações reprodutivas e neurológicas. Apresenta em seu ciclo de vida, hospedeiros intermediários, dentre os quais estão os caprinos, e hospedeiros definitivos, representado pelos canídeos. O estudo foi desenvolvido no estado do Rio Grande do Norte em parceria com a Empresa Brasileira de Pesquisa Agropecuária (EMBRAPA). Foram visitadas e pesquisadas duas Mesorregiões produtoras (Central e Oeste Potiguar), com objetivo de realizar estudo epidemiológico de anticorpos anti-N. caninum aplicou-se questionários de caracterização zoosanitária, além da coleta de sangue para obtenção de soros, estes foram estocados a -20oC, para posterior análise na EMBRAPA Gado de Corte. As amostras de soro foram submetidas à técnica de Imunofluorescencia Indireta (RIFI ≥ 1:50) e avaliadas utilizando análise univariada e multivariada para verificação dos fatores de risco. Os resultados sorológicos demonstraram elevada presença de anticorpos anti-N. caninum, com prevalência de 36,5% variando de zero a 100% dentro das propriedades estudadas. Dentre os fatores de risco, o sistema de criação foi o que apresentou o maior índice de correlação com o agente, seguida da fonte de água e presença de cães selvagens as instalações, influenciando diretamente na presença do protozoário na caprinocultura Norte rio grandense

Perdas devido à natimortalidade, mumificação fetal, abortamentos e morte embrionária são responsáveis por uma considerável queda no desempenho da indústria suinícola no Brasil e no mundo. Dentre os agentes mais freqüentemente descritos como causadores de falhas reprodutivas em suínos pode-se citar o Parvovírus suíno, Leptospira spp. O diagnóstico das causas infecciosas de mortalidade embrionária e fetal torna-se muitas vezes inviável pelo estado de autólise do material ou dificuldades inerentes às características de crescimento do vírus ou bactéria envolvido. O presente estudo teve por objetivo avaliar os resultados obtidos no período de oito anos de detecção de Parvovirus suíno e Leptospira spp. em falhas reprodutivas e discutir alguns aspectos relativos ao diagnóstico destas infecções. Foram avaliados 1901 fetos, sendo coletadas de cada animal, uma amostra de pool de órgãos e uma de conteúdo gástrico, perfazendo um total de 3642 análises. Observou-se uma freqüência de 27,6% dos fetos positivos para Parvovirus suíno, 19,8% positivos para Leptospira spp e 1,1% positivos para os dois agentes em associação. Dentre as 339 granjas avaliadas em oito Estados Brasileiros, 48,5% foram positivas para um ou ambos agentes pesquisados. Avaliou-se a freqüência de fetos positivos em casos de abortamento, natimortalidade e mumificação fetal e comparou-se a eficiência da pesquisa dos agentes em amostras de órgãos, conteúdo gástrico e em ambos. Os resultados obtidos indicam a grande importância destes agentes infecciosos nos quadros de falha reprodutiva em granjas de suínos no Brasil, apesar da ampla utilização de vacinas contra os mesmos. . / Losses due to stillbirths, mummification, embryonic death and abortions account for a considerable drop in performance of the pig industry in Brazil and the world.
