A presente tese objetiva trazer subsídios para a discussão em torno de uma realidade recente no Brasil, qual seja, a crescente utilização de instrumentos financeiros pelas companhias abertas vis a vis seu objeto social, o que exige a proteção de seus investidores e credores. É tratada a tutela do objeto social na legislação societária para as companhias abertas, tipo específico de sociedade escolhido pela gama de interesses que a cercam e pela importância no atual estágio de desenvolvimento do mercado de capitais. Para tanto, será demonstrada a utilidade da cláusula do objeto social na realidade das companhias abertas segundo um ponto de vista tríplice, (i) a disciplina do contrato, (ii) a capacidade de agir da sociedade e (iii) os atos ultra vires praticados pelos administradores, abordando o princípio da boa-fé, teoria da aparência, abuso de poder, em suas modalidades de excesso de poder e desvio de poder, à luz de uma nova realidade descortinada pela crise global de 2008, pela evolução tecnológica e disseminada utilização de complexos instrumentos financeiros. Verificando-se a utilização de instrumentos derivativos complexos e de derivativos de câmbio pelas companhias abertas em operações realizadas no mercado de balcão, de forma pouco transparente e sem controle adequado do risco, que acarretaram substanciais prejuízos em detrimento de todos os acionistas, apresenta-se como indagação se tais operações financeiras especulativas extrapolaram o conteúdo do objeto social e se poderiam, ou não, ter sido contratadas. / This thesis purports to provide arguments in connection with a current reality in Brazil, consisting of the increasing use of financial instruments by publicly-held companies vis a vis their corporate purpose, what requires the protection of investors and creditors. This thesis addresses the rules related to the corporate purpose that are provided for in the corporation law, and that are applicable to publicly-held companies, a corporate type which is elected by various interests surrounding it and by the importance in the current development of the capital market. In this respect, the utility of the corporate object clause in the activity of publicly-held companies will be demonstrated through a triple point of view: (i) the rules related to the corporate by laws; (ii) the companys capacity to act; and (iii) the ultra vires acts performed by the managers of the company, in view of the good-faith principle, disregard institute, abuse of rights, in its modalities of exciding rights and deviation of rights, in the context of the 2008 global crisis, the technological progress, as well as the wide use of complex financial instruments. In view of the use of both sophisticated derivative instruments and foreign exchange derivatives by publicly-held companies in transactions carried out on the over-the-counter market, in a non-transparent manner and without appropriate risk-control, which resulted in substantial losses to all shareholders, it lights up the discussion whether such speculative financial transactions exceeded the limit of the relevant corporate object, and whether they could, or could not, be agreed upon.

v anglickém jazyce In this thesis called "Perspective Orientation of Girls Situated in Diagnostic Institution" I deal with young people with behavioral disorders. In the first part I am trying to describe the meaning of term adolescence. I tried to describe the main problems of this phase of life and show to reader spectrum or variety of risk and delinquent behavior. I shortly introduced topic of perspective orientation and described function of Diagnostic Institution. In practical part I firstly described methods of research. Partially I used printed documents for part of my research. Second and the main part is based on personal written works of clients themselves. By form of open questions I tried to learn ideas of clients about the future. In the first part of research I tried to understand family background of respondents and socio-economic status of their families. I was also interested in region girls came from. Finally, I was interested in reasons why clients are in Diagnostic Institution. Is it because of drugs or something completely different? In the second part of my research I used technique of interview directly with clients. I tried to analyze and valuate results. I compare my findings with other studies on this subject and find and describe similarities and differences. Besides...

Since the early 1990s with the AIDS pandemic, there has been an increasing interest on the importance of risky sexual behaviors, especially among men who have sex with men (MSM). An important antecedent for these behaviors is alcohol use. Studies consistently show an increased frequency of both alcohol use and risky sexual behaviors in MSM populations. However, to date, there has not been a precise estimate of the effect size in these diverse populations and a consistent way to measure it. More so, the importance of context is often cited as a source of variability, but is rarely measured in these studies. Contextual factors are different and specific for MSM, as they have been approached by two theories, both of which will be guiding this dissertation: Singer’s Syndemic Theory and Meyer’s Minority Stress Theory. Chapter 1, then presents a comprehensive review of both theories as they apply to alcohol use, risky sexual behaviors, and contextual factors driving them. Chapter 2 answers the first research question about effect sizes through a systematic literature review. The effect sizes or measures of association of these contextual risk and protective factors were summarized using meta-analytic techniques. Using five electronic databases, we identified 26 studies in 26 years (1990–2015), all diverse in terms of sampling techniques, assessment of sexual orientation, operationalization of alcohol use and risky sexual behaviors, contextual factors included, and measurement of effect sizes. Despite this diversity, studies reporting an effect size were pooled and summarized using both descriptive and meta-analytic techniques, as appropriate. Meta-analyses were conducted using Cochrane’s guidelines for generic inverse variance outcomes with random effects. The pooled effects of alcohol use on condomless anal intercourse (CAI; OR 1.73 [95% CI 1.43, 2.10], I2 0%), heavy episodic drinking on CAI (OR 1.88 [95% CI 1.25, 2.81], I2 32%), and heavy episodic drinking on condomless oral sex (OR: 8.00; 95% CI 2.48, 25.81), as well as the effects of substance use, mental health status, violence and victimization, and self-reported HIV status as contextual factors in the pathway between alcohol use and risky sexual behaviors were calculated, reported, and discussed along with study limitations and implications for public health. Chapter 3 answers the second research question regarding a standardized measurement model for effect sizes and the multiple mediation of contextual factors. We used the male subset of Wave IV of the AddHealth dataset to test our hypotheses through structural equation modeling approaches, including measurement analysis with invariance testing, path analysis for direct effects, and multiple mediation analysis through bootstrapping for indirect effects. The AUD scale was invariant between MSM and MSW, but the risky sexual behavior scale was not. For MSM, the standardized direct effect of AUD onto risky sexual behaviors was –1.25 and the standardized total indirect effect of the multiple mediation model was 1.58, 95% CI [1.42, 1.73]. Among the mediators, the strongest indirect effect for any measured or latent mediator was the mental health construct (2.09). We conclude that even though AUD has the same measurement structure for MSM and MSW, its effect on risky sexual behaviors does not operate the same way for these two populations, supporting both causal and contextual behavioral theories. Conclusions are individually discussed, respectively, in Chapters 2 and 3. However, Chapter 4 puts both manuscript conclusions in context and further discusses future implications for public health research, practice, and policy.

HIV/Aids has become a household term in South Africa. Most people are aware of the existence of the disease and how it is transmitted. Several people have used this information as the impetus for behaviour change but there are many individuals who have not heeded this call and have not made any significant changes to their lifestyles. This is reflected in South Africa’s high infection rate. It would seem as if, for various reasons, people know how to protect themselves but have not used this knowledge to guard against possible infection. The purpose of this study is to explore the reasons why people have not changed their behaviour and to identify possible techniques that can be used to amend this situation. This will take the form of an intensive three-day prevention workshop where participants will be asked to think critically about their own behaviour. The aim of the programme will be to discuss, demystify and debate ideas. How will this programme be designed? The researcher will make use of focus groups consisting of Technikon students who will offer their thoughts and opinions. Once these focus groups have been conducted the researcher will undertake an intensive analysis of the data and identify certain key issues. A literature review will then follow. Therefore, the foundation of this programme will be based on the ideas of the participants, the researcher’s ideas and some points from formal behaviour change theories. The goal of this study is to add to the already growing body of HIV/Aids prevention literature and to design a programme that is useful and relevant. / Dissertation (MA (Counselling Psychology))--University of Pretoria, 2006. / Psychology / unrestricted

This study was designed to determine the prevalence of substance use and risky sexual behaviours among university students in Ethiopia and examine whether personality traits predict substance use and risky sexual behaviours. Using a cross-sectional quantitative design, data were obtained from 2620 undergraduate students selected through stratified multistage sampling. Personality traits were measured through John, Donahue, and Kentle‘s (1991) Big Five Inventories [BFI-44]. Substance use and risky sexual behaviours were assessed using risky behaviour scales adapted from Miller et al. (2004) and Zuckerman and Kuhlman (2000). Statistical analysis was performed using Statistical Package for Social Sciences (SPSS) Version 20 and Analysis of Moment Structure (AMOS) Version 22 software. The findings revealed that 72.18% of the respondents reported that they have used at least one kind of substance in their lifetime and 50.27% of the participants had consumed at least one kind of substance in the past 30 days before the survey. The current prevalence of substance use was 46.3%, 16.1%, 9.9%, 6.8%, and 5.0% for drinking alcohol, chewing khat, smoking shisha, smoking cigarettes and marijuana use respectively. About 40.2% of respondents had sexual intercourse at least once in their lifetime and 25.6% had sex in the past three months before the study. Among sexually active respondents, 35% began sexual intercourse at the age of 17 years old or younger; 64.3% had multiple sexual partners; 53.1% had substance-induced sex, 62.03% had unsafe sex, and 45.3% had casual sex at least once. Males were found to be more at risk of substance use and risky sexual behaviours. Analysis of the structural relation revealed that conscientiousness and agreeableness traits were significant negative predictors and extraversion was a significant positive predictor of substance use and risky sexual behaviours. Neuroticism had a significant direct effect only on substance use. Substance use mediated the effect of personality traits on risky sexual behaviours. There was gender moderation or variation on the effect of personality traits on substance use and risky sexual behaviours. Therefore, the findings may imply that health risk behaviours were highly prevalent among students, which requires special prevention and intervention. Personality traits can be used to identify the vulnerable individuals and design programs aimed at developing behaviours underlying the protective traits. / Psychology / D. Litt. et Phil.

Objective: To examine health services use on the basis of alcohol consumption. Material and Methods: A cross-sectional study was carried out on patients visiting the Primary Health Care (PHC) settings in Catalonia during 2011 and 2012; these patients had a history of alcohol consumption. Information about outpatient visits in the PHC setting, hospitalizations, specialists’ visits and emergency room visits for the year 2013 was obtained from 2 databases (the Information System for the Development of Research in PHC and the Catalan Health Surveillance System). Risky drinkers were defined as those who consumed more than 280 g per week for men or more than 170 g per week for women, or any amount of alcohol while being involved in a high risk work activity, or taking medication that significantly interferes with alcohol or when being pregnant. Binge drinkers (>60 g in men or >50 g in women in a short amount of time more than once a month) were also considered risky drinkers. Results: A total of 606,948 patients reported consuming alcohol (of which 10.5% were risky drinkers). Risky drinkers were more likely to be admitted to hospitals or emergency departments (range of ORs 1.08–1.18) compared to light drinkers. Male risky drinkers used fewer PHC services than male light drinkers (OR 0.89, 95% CI 0.87–0.92). In general, risky alcohol users used services more and had longer hospital stays. When stratifying by socioeconomic level of the residential area, we found that risky drinking failed significance, while current or past cigarette smoking was associated with higher healthcare use. Conclusions: Risky drinkers use more expensive services, such as hospitals and emergency rooms, but not PHC services, which may suggest that prevention strategies and alcohol interventions should also be implemented in those settings.

Background: Due to technological outbreak Massively Multiplayer Online (MMO) has become very popular leisure time occupation for people of various age ranging from not only children to also mid-age gamers. Although computer gaming is not officially classified as a disorder within ICD-10, it shows obvious signs of behavioral disorder. Despite there is a great number of research within this area, there is still lack of unified definition and classification. In addition to numerous publications in this field, there is still a space for additional research. One of those areas to explore is an impact on partner life and relationship. Aims: The main objective of the thesis is to describe the impact of Massively Multiplayer Online gaming on partner relationship. Furthermore, the work will partially focus on the role of playing MMO games in a partnership and what the impact of playing Massively Multiplayer Online games are in the common social life of partners. Methods and sample size: Qualitative research, where data has been collected from semi-structured interview, has been chosen. Subsequently the data has been extrapolated by method of Grounded Theory. Sample size was chosen based on online questionnaire with 733 participants out of those there were 5 male gamers and 4 female partners. Results: The...

The objective of this study was to examine the association between risky sexual behavior and contextual factors related to economic resources, woman’s empowerment, and health facility characteristics among young women in Zomba district, Malawi. Secondary analyses of the Schooling, Income, and Health Risk (SIHR) study were undertaken. Four outcomes related to risky sexual behavior were examined: if participants had ever had sex, consistent condom use, and two scores measuring risk related to partner history and age during sexual activity. Regression models with cluster-robust standard errors and multilevel regression models were used to estimate associations; analyses were stratified by school enrolment status at baseline of the SIHR study and utilized weights to account for SIHR sampling design. For participants in school at baseline, the percent of girls enrolled in school at the community level was associated with ever having sex and consistent condom use. Belief in the right to refuse sex was protective against ever having sex, lower household education was associated with higher odds of ever having sex, and near rural and far rural residence was associated with decreased odds of condom. For participants not in school at baseline, lower individual education was associated with riskier scores related to age and partner history and lower household education was associated with lower age during sexual activity. Private or non-governmental health facilities were associated with decreased odds of condom use and higher age during sexual activity. In both strata, increasing age and near rural residence (within 16 kilometers of urban center) increased odds of ever having sex; lower educational achievement was associated with lower age during sexual activity. A history of pregnancy was associated with lower odds of condom use and riskier partner history. Risky sexual behavior is multifaceted and complex. While various factors related to women’s empowerment played a role, the most consistent variables associated with risky sexual behavior were those related to education. Interventions and programs seeking to reduce risky sexual behavior among young women, thereby reducing their risk of HIV infection, should continue to focus on improving access to education at multiple levels.

TITLE: Truancy and school attendance rejection at high school ABSTRACT: Risky behavior among adolescents is a serious society-wide phenomenon. In this context was carried the first research of medical high schools in Karlovy Vary region in school year 2007/2008 which was generally focused on all kinds of risky behavior. From this research have come out, besides others, that 30.80 % of students committed truancy. This work is focused on the issue of truancy and school attendance rejection based on the increasing tendency of truancy. The theoretical part defines truancy, its causes, diagnosis, consequences, intervention and legislative of this issue. Truancy and school attendance rejection for pupils in the 1st and 4th grade at Medical High School in Karlovy Vary analysis, evaluation of related factors influencing truancy and school attendance rejection and comparison of the obtained results was the purpose of the research part. The information from own anonymous questionnaires completed by 180 respondents were used in the practical part. Data analysis confirmed high and still growing number of truants among Medical High School in Karlovy Vary. The results provide many information from which it is possible to deduce concrete preventive measures. KEYWORDS: truancy, school attendance rejection, risky behavior,...

Background: School prevention programs of risky behavior should be an important part of the education of children and adolescents. The programs are implemented by each school individually according to the elaborated Minimum Preventive Program (MPP) and their mediation and implementation is supervised by the school prevention methodologist (ŠMP). Within the Prague 6 City District, there is close cooperation between ŠMP, the prevention methodologist from the pedagogical- psychological counseling center and the drug coordinator. The aim of this cooperation is to ensure quality of prevention in local schools and in the wider community of the municipality. Objectives: The aim of the study is to map the process of implementation of programs of general school primary prevention of risky behavior in primary schools in the administrative district of Prague 6 in terms of performance of the function of the ŠMP, elaboration of MPP and implementation of preventive programs. Methods: A mixed-method design was used, combining a questionnaire study with ŠMP from the district of Prague 6 with a group discussion with six respondents who participated in the questionnaire study. The questions in the questionnaire are based on questions in the SEPA preventive activity reporting system and on the questionnaire used in...
