Vécue comme l’une des plus grandes crises qu’a connue notre génération, la propagation du virus du SIDA est une urgence mondiale sans précédent, notamment en Afrique sub-saharienne où vivent la grande majorité des individus séropositifs. Dans un contexte où aucun vaccin n’existe encore et où les traitements sont onéreux et peu accessibles, les campagnes d’information sur le virus et l’acquisition de connaissances sur les méthodes de prévention, notamment à travers les programmes scolaires, sont cruciaux. La scolarisation est souvent vue comme la solution pour enrayer la propagation du virus et plusieurs études effectuées en Afrique sub-saharienne ont effectivement montré que les individus scolarisés étaient souvent les mieux renseignés sur le VIH/SIDA et son mode de propagation. Au Cameroun, pourtant, la partie de la population qui est la plus touchée par la séropositivité est aussi la plus instruite. C’est sur cet apparent paradoxe que se penche la présente étude. Cette recherche explore les différents facteurs qui sous tendent la relation positive entre le niveau d’instruction et la séropositivité au Cameroun en analysant les données de l’Enquête Démographique et de Santé (EDS) de 2004. Les résultats des analyses bivariées montrent que plus le niveau d’instruction des hommes et des femmes camerounais augmente, mieux ces derniers sont informés sur le VIH et ses modes de transmission. Malgré cet avantage au niveau des connaissances, l’analyse confirme un lien positif entre le niveau d’instruction et la séropositivé fort et statistiquement significatif parmi les femmes camerounaises, mais non significatif chez les hommes. Les résultats des analyses logistiques hiérarchiques suggèrent que c’est une combinaison de facteurs qui explique pourquoi les femmes les plus scolarisées sont aussi les plus touchées par le VIH/SIDA. Le fait qu’elles aient un profil sociodémographique différent (qu’elles soient plus jeunes et plus riches notamment), et qu’elles soient plus urbaines que leurs consœurs moins scolarisées, mais surtout qu’elles aient un temps d’exposition au risque hors union plus long et un nombre de partenaires plus élevés exposent davantage les femmes les plus scolarisées au virus. / Considered the biggest crisis known to our generation, the propagation of the AIDS virus is an unprecedented worldwide emergency, notably in sub-Saharan Africa where the majority of HIV-positive individuals live. In a context where no vaccine exists and where treatments are expensive and difficult to access, information campaigns about the virus and the acquisition of knowledge on prevention, notably through school programs, are essential. Schooling is often seen as the solution to eradicate the propagation of the virus, and studies held in sub-Saharan Africa have actually shown that highest educated individuals are more informed about HIV/AIDS and about its transmission. However, in Cameroon, the most affected part of the population is also the most educated one. This study investigates this apparent paradox. Using the 2004 data from the Demographic and Health Surveys (DHS), this research explores the multiple factors explaining the positive relation between the education level and seropositivity in Cameroon. Result from the bivariate analysis show that the level of knowledge about HIV and its transmission increases with the education level of men and women. In spite of this knowledge advantage, the analysis show a strong, positive and statistically significant link between the education level and seropositivity of women, but this link is not significant with men. The results of the hierarchical logistical analysis suggest that a combination of factor explains why the most educated women are more affected by HIV/AIDS. The fact that those women have a different sociodemographic profile (they are younger and wealthier), and that they live in more urban areas than their less educated counterparts, and especially the fact that they have a longer exposition time to HIV before engaging in a union, as well as an a higher number of sexual partners, increases their exposure to the virus.

There is an increasing interest in within-group agreement in organizations, in response to evidence that agreement is predictive of various outcomes of interest. The model in this study suggests that within-group agreement on perceptions of the work environment is predicted indirectly by the quality of exchange relationships, specifically team-member exchange (TMX), leader-member exchange (LMX), social interaction and work interdependence, through the mediation of social influence, and directly by demographic homogeneity. Chan's (1998) typology of composition models was used to appropriately conceptualize the variables at the group level.Results suggest that average high quality LMX relationships are predictive of within-group agreement, and that high quality relationships within the team are predictive of perceptions of social influence within the team. The mediation model was non-significant, and contrary to existing literature, social interaction and work interdependence were not significantly related to any of the other variables in the model.Demographic homogeneity was related to both perceptions of social influence and to within-group agreement on perceptions of the work environment in the opposite direction from that hypothesized. Post-hoc analyses suggest that organizational cultural orientation (collectivist or individualist) may moderate the relationship between demographic homogeneity and within-group agreement on perceptions of the work environment.

The present study examined the relationships of depression, social support, and socio-demographic factors on health behaviors of mothers with preterm infants hospitalized in the neonatal intensive care unit (NICU). In addition, the study also assessed the moderation effect of social support on the relationship between depression and health behaviors. Eighty-nine mothers with hospitalized infants in the central Richmond area participated in the study. Analyses found that mother’s education level and her marital status to be significantly associated with her health behaviors. Mothers with a higher level of education and those who were married, were less likely to smoke and more likely to incorporate high fiber foods in their diet. In addition, the more support a mother perceived from family and friends, the less likely she was to smoke cigarettes. Neither depression nor social support from the father was significantly related to health behaviors. This study did not find social support to be a moderator between depression and health behaviors. However, the study found direct effects of socio-demographic factors and certain types of support on health behaviors. Assessing a mother’s personal and interpersonal factors will inform clinicians of possible areas of interventions for mothers during the postpartum period.

Especially for last three decades many of the scholars have tried to provide general terrorist profile, which is commonly usable for all terrorists. They were seeking to identify the process of becoming terrorist (Sageman, 2004; Russel&Miller, 1977; Strentz, 1988; Hassan, 2001). The main problem on those studies is that, without looking at degree of involvement of terrorist they just focus on “who becomes a terrorist and why” and they prefer to ignore different type of characteristics about terrorist. Yilmaz (2009) tried to underline and answer this subject by studying on arrest results about DHKP/C and Hizbullah terrorist organizations in Turkey. This study aims to analyze socio-demographic and motivational differences of PKK terrorist organization members who are belong to different involvement degrees (active participant and supporter).

This thesis concerns the old age in the context of human life and the problems of senior discrimination. It's divided into two parts, theoretic and empiric. In theoretic part the old age and ageing are characterized, the aspects of old age are analysed and the role of gerontopedagogic is defined. With respect to demographic prospect, the gravity of senior discrimination is emphasized as an undesirable social-pathological phenomenon. In empiric part, the author tries to reveal on the basis of field research, whether today's seniors feel being discriminated. The extent of discrimination is being compared between the seniors living by them own in a big city (Prague) and smaller town (Vrchlabí). The work is focused on identification of circumstances, which can influence the senior discrimination, and tries to answer, which parts of social life are projected to the discrimination of old people. Key words: old age, ageing, aspects of ageing, senior, senior education, demographic prospect, ageism

The aim of this work is to analyze the changes in family behavior in Czech Republic especially using the framework of the second demographic transition. Attention was focused on the analysis of attitudes towards new form partnerships and childbearing and development reproductive behavior in Czech Republic. In this analysis using data of two surveys ISSP (1994, 2002, 2012) and EVS (1990, 1999, 2008). The trajectories of changes in Czech Republic were compared with trajectories of transformation in selected post-communist countries. Different trajectories of transformation have been identified for postcommunist countries. The results in many aspects suggested Czech Republic has been approaching the North-western European countries. However, important the Czech Republic seems to be much further in the process of the second demographic transition in comparison with many post- communist countries. Keywords family behavior, attitude, family, the second demographic transition, postcommunist countries

Obtaining variances for the plug-in estimator of the Gini coefficient for inequality has preoccupied researchers for decades with the proposed analytic formulae often being regarded as being too cumbersome to apply, as well as usually based on the assumption of an iid structure. We examine several variance estimation techniques for a Gini coefficient estimator obtained from a complex survey, a sampling design often used to obtain sample data in inequality studies. In the first part of the dissertation, we prove that Bhattacharya’s (2007) asymptotic variance estimator when data arise from a complex survey is equivalent to an asymptotic variance estimator derived by Binder and Kovačević (1995) nearly twenty years earlier. In addition, to aid applied researchers, we also show how auxiliary regressions can be used to generate the plug-in Gini estimator and its asymptotic variance, irrespective of the sampling design. In the second part of the dissertation, using Monte Carlo (MC) simulations with 36 data generating processes under the beta, lognormal, chi-square, and the Pareto distributional assumptions with sample data obtained under various complex survey designs, we explore two finite sample properties of the Gini coefficient estimator: bias of the estimator and empirical coverage probabilities of interval estimators for the Gini coefficient. We find high sensitivity to the number of strata and the underlying distribution of the population data. We compare the performance of two standard normal (SN) approximation interval estimators using the asymptotic variance estimators of Binder and Kovačević (1995) and Bhattacharya (2007), another SN approximation interval estimator using a traditional bootstrap variance estimator, and a standard MC bootstrap percentile interval estimator under a complex survey design. With few exceptions, namely with small samples and/or highly skewed distributions of the underlying population data where the bootstrap methods work relatively better, the SN approximation interval estimators using asymptotic variances perform quite well. Finally, health data on the body mass index and hemoglobin levels for Bangladeshi women and children, respectively, are used as illustrations. Inequality analysis of these two important indicators provides a better understanding about the health status of women and children. Our empirical results show that statistical inferences regarding inequality in these well-being variables, measured by the Gini coefficients, based on Binder and Kovačević’s and Bhattacharya’s asymptotic variance estimators, give equivalent outcomes. Although the bootstrap approach often generates slightly smaller variance estimates in small samples, the hypotheses test results or widths of interval estimates using this method are practically similar to those using the asymptotic variance estimators. Our results are useful, both theoretically and practically, as the asymptotic variance estimators are simpler and require less time to calculate compared to those generated by bootstrap methods, as often previously advocated by researchers. These findings suggest that applied researchers can often be comfortable in undertaking inferences about the inequality of a well-being variable using the Gini coefficient employing asymptotic variance estimators that are not difficult to calculate, irrespective of whether the sample data are obtained under a complex survey or a simple random sample design. / Graduate / 0534 / 0501 / 0463 / aahoque@gmail.com

The main theme of the diploma thesis is the senior's demand after the tourist services. The diploma thesis defines the main characteristics of the senior segment, its individual attributes and travel behaviour. It also presents the actual offer in tourism for this segment and its possible progress. The diploma thesis is divided into six chapters.

The thesis is focused on the current state of families in the Czech Republic and its individual regions. In addition to the basic characteristics of the family, this work captures the changes undergone by the family, especially in the areas of marriage and parenthood. The diploma thesis also analyzes the behavior of the Czech population through relevant statistical indicators, such as marriage, divorce, birth and fertility in the period of 1991-2008, both at the national level and at the district levels. Based on the analysed results of the statistical indicators, the author assesses whether there exist differences between individual regions of the Czech Republic, which relate to the family behavior of the population.

Thesis (M.A.(Demography and Population Studies))--University of the Witwatersrand, Faculty of Humanities, School of Social Sciences, 2016 / BACKGROUND: Under-5 children in KwaZulu-Natal are highly exposed to dying before reaching five years of life. Studies have been conducted to understand the demographic and socioeconomic factors that influence under-5 mortality, both nationally and internationally, with some contradicting findings on the association between some socioeconomic and demographic factors and under-5 mortality. While some studies found child mortality to be significantly associated with rural geographical place of residence, the reverse has also been established. The purpose of this study was to examine the association between socioeconomic and demographic factors and under-5 mortality in KwaZulu-Natal, South Africa. DESIGN: The study was cross-sectional, and utilises 2011 Census secondary data set from Statistics SA. Overall, the census revealed that 55 476 children under the age of 5 had died in the 12 months prior to the census nationally. In KwaZulu-Natal this figure was 15 356. The 10% sample showed that 1 474 under-5 children had died in the same period in KwaZulu-Natal. STATA 12.0 was used for the analysis. Binary logistic regression model was used to examine the association between under-5 mortality and the independent variables. RESULTS: The major findings of the study indicated that (i) male children were 1.22 times more likely to die compared to female children under the age of 5 years; (ii) mothers who had no schooling (AOR=1.82); mothers with primary level of education (AOR=2.43); and mothers with secondary level of education (AOR=1.77), were more likely to experience under-5 mortality compared to mothers with tertiary level education; (iii) mothers whose age at first birth was between 15-19 years (AOR=1.47) and those whose age at first birth was between 25-34 years (AOR=2.14) were more likely to experience under-5 mortality compared to mothers whose age at first birth was between 35-49 years; (iv) Black mothers were more likely to experience under-5 mortality compared to Indian mothers (AOR=5.99); (v) mothers who were employed were 1.22 times more likely to experience under-5 mortality compared to unemployed mothers. Lastly, under-5 mortality was less likely amongst mothers in the medium households compared to those from low income households (AOR=0.65). CONCLUSION: This study found that socioeconomic and demographic factors substantively determine under-5 mortality in KwaZulu-Natal. Evidence from this study suggest that interventions aimed at reducing under-5 mortality should focus on black women, the younger women, the less educated and those with low household income. / MT2017
