Background: Previous research has reported both a moderate degree of comorbidity between cannabis dependence and major depressive disorder (MDD) and that early-onset cannabis use is associated with increased risks for MDD. Objective: To examine whether associations between both lifetime cannabis dependence and early cannabis use and measures of MDD, suicidal ideation, and suicide attempt persist after controlling for genetic and/or shared environmental influences. Design: Cross-sectional survey of twin pairs discordant for lifetime cannabis dependence and those discordant for early cannabis use. Setting: General population sample of twins (median age, 30 years). Participants: Two hundred seventy-seven same-sex twin pairs discordant for cannabis dependence and 311 pairs discordant for early-onset cannabis use (before age 17 years). Main Outcome Measures: Self-report measures of DSM-IV-defined lifetime MDD, suicidal ideation, and suicide attempt. Results: Individuals who were cannabis dependent had odds of suicidal ideation and suicide attempt that were 2.5 to 2.9 times higher than those of their non-cannabis-dependent co-twin. Additionally, cannabis dependence was associated with elevated risks of MDD in dizygotic but not in monozygotic twins. Those who initiated cannabis use before age 17 years had elevated rates of subsequent suicide attempt (odds ratio, 3.5 [95% confidence interval, 1.4-8.6]) but not of MDD or suicidal ideation. Early MDD and suicidal ideation were significantly associated with subsequent risks of cannabis dependence in discordant dizygotic pairs but not in discordant monozygotic pairs. Conclusions: Comorbidity between cannabis dependence and MDD likely arises through shared genetic and environmental vulnerabilities predisposing to both outcomes. In contrast, associations between cannabis dependence and suicidal behaviors cannot be entirely explained by common predisposing genetic and/or shared environmental predispositions. Previously reported associations between early-onset cannabis use and subsequent MDD likely reflect shared genetic and environmental vulnerabilities, although it remains possible that early-onset cannabis use may predispose to suicide attempt.

There is concern that children’s health is being compromised by a decline in physical activity occurring as a result of the changing nature of the occupations of childhood. This article reports the findings of in-depth interviews conducted with six children and their parents when the children were between 7 and 8 years and then again when they were between 9 and 10 years. This longitudinal perspective highlighted features associated with children remaining engaged in physical occupations. Factors found to contribute to continued involvement in exercise and sports were: the initial introduction to the activity being pleasurable; same-sex parents or older siblings being directly involved; and the skills required by the occupations being commensurate with children’s developmental level. These findings help inform occupational scientists about the nature of recreational and leisure occupations, and how they are introduced and framed within the context of children’s occupational roles.

Em diversas ocasiões, os líderes da Igreja Presbiteriana do Brasil revelaram o desejo de uma eqüidistância teológica dos extremos liberais e fundamentalistas. Entretanto, os dis-cursos e as práticas dessa instituição eclesiástica contrastam com esse posicionamento ofici-al. Além disso, essa pretensa posição de eqüidistância dos extremos liberais e fundamenta-listas não denota fronteiras rígidas, mas é um instrumento eficaz de legitimação do poder nos momentos de reconfiguração do campo religioso, principalmente em situações de crises internas. Outrossim, após a redemocratização do Brasil e o conseqüente aumento de plura-lismo religioso, houve a transformação do campo social brasileiro, provocando dificuldades em setores mais conservadores dessa instituição. Atualmente, procura-se revitalizar a pró-pria tradição religiosa diante das ameaças de sua dissolução impostas pelos processos e-mancipatórios modernos e pela influência das concepções seculares e supostamente atéias da vida (como o feminismo, a luta em defesa dos direitos reprodutivos, a união civil entre pessoas do mesmo sexo, o chamado ―movimento de lésbicas, gays, bissexuais, travestis e transgêneros‖ etc.). No campo religioso, os resultados imediatos dessa postura de reação em face das transformações sociais impostas pela modernidade são: (1) misoginia; (2) aquela manifestação de ativismo político-religioso de caráter conservador os protestantes de pen-dor fundamentalista, cuja expansão no Brasil se vem processando há muitas décadas, em ritmo sabidamente veloz, com base em um modelo de proselitismo muito bem-sucedido entre as camadas mais pobres da população brasileira, por todo território nacional.(AU)

In this article we describe and evaluate the process of conducting online survey research about the legal recognition of same-sex relationships (key findings from which we have reported elsewhere, see Harding and Peel, 2006). Our aim in so doing is to contribute to the growing generic literature on internet-based research methods (Nosek et al., 2002; Rhodes et al., 2003; Stern, 2003; Strickland et al., 2003; Thomas et al., 2000) to the research methods literature within lesbian, gay, bisexual, trans and queer (LGBTQ) psychologies (Fish, 2000; Morris and Rothblum, 1999; Meezan and Martin, 2003; Mustanski, 2001) and also to extend the germinal literature focusing on internet research with non-heterosexual groups (Elford et al., 2004; Ellis et al., 2003; Ross et al., 2000). We begin by discussing the process of developing the online survey tool, before outlining the experience of the survey ‘going live’ and providing details of who completed the survey. We conclude by exploring some of the positives and pitfalls of this type of research methodology.

This work chronicles how queer individuals politicized their same-sex desires from the post-World War II era to the mid-1990s. Using Miami as a site of exploration, this work demonstrates the shift from understanding homosexuality as a same-sex "desire" to a distinct form of "civil rights." It argues that by no means was it inevitable that queer issues entered the American political mainstream. This project pays particular attention to Miami's Cuban exile community, as it managed to garner great socio-political power in the city. Like others in the city's power structure, Miami's Cuban exiles were also fundamentally traditionalists. Together, these phenomena crystallized into a matrix of obstacles that stunted the growth of the gay rights movement. This work demonstrates the historical dynamics of sexuality and politics by contextualizing immigration, ethnicity, race, consumerism, and Cold War domestic and foreign policy.

The balance between the costs and benefits of conspicuous signals ensures that the expression of those signals is related to the quality of the bearer. Plastic signals could enable males to maximize conspicuous traits to impress mates and competitors, but reduce the expression of those traits to minimize signaling costs, potentially compromising the information conveyed by the signals. ^ I investigated the effect of signal enhancement on the information coded by the biphasic electric signal pulse of the gymnotiform fish Brachyhypopomus gauderio. Increases in population density drive males to enhance the amplitude of their signals. I found that signal amplitude enhancement improves the information about the signaler's size. Furthermore, I found that the elongation of the signal's second phase conveys information about androgen levels in both sexes, gonad size in males and estrogen levels in females. Androgens link the duration of the signal's second phase to other androgen-mediated traits making the signal an honest indicator of reproductive state and aggressive motivation. ^ Signal amplitude enhancement facilitates the assessment of the signaler's resource holding potential, important for male-male interactions, while signal duration provides information about aggressive motivation to same-sex competitors and reproductive state to the opposite sex. Moreover, I found that female signals also change in accordance to the social environment. Females also increase the amplitude of their signal when population density increases and elongate the duration of their signal's second phase when the sex ratio becomes female-biased. Indicating that some degree of sexual selection operates in females. ^ I studied whether male B. gauderio use signal plasticity to reduce the cost of reproductive signaling when energy is limited. Surprisingly, I found that food limitation promotes the investment in reproduction manifested as signal enhancement and elevated androgen levels. The short lifespan and single breeding season of B. gauderio diminishes the advantage of energy savings and gives priority to sustaining reproduction. I conclude that the electric signal of B. gauderio provides reliable information about the signaler, the quality of this information is reinforced rather than degraded with signal enhancement.^

This dissertation analyses the Brazilian Supreme Court’s judgement in the Non-compliance Action of the Fundamental Precept 132/RJ and in the Direct Action of Unconstitutionality 4277/DF, which created in the country the same-sex civil union. In This decision, the STF interpreted according to the constitution Article 1.723 of the Civil Code, invoking several fundamentals reaffirmed in the Constitution. From all these laws invoked by the Supreme Court to support the pretorian creation, the content of consitutional Law regarding equality is the only that corresponds, and it is sufficient to evidence the necessity of the creation, by legislator, of the institute for civil rights, since the Constitution forbids distinctions that is not expressly provided for in the Constitution (Art. 3º, IV, of Federal Constitution). In this way, Article 226, § 3º is not an exception capable of satisfying the condition of the consitutional foresight because although it protect, according its content only the civil union “between the man and the woman”, it is not able to forbid the creation, by legislator, of another kinds of families, including the same-sex civil union. As such, the reasoning, now legitimate according to the legislator, is not support the creation of institute by Constitutional Court, because the Court may enforce the Law, interpreting in the purviews allowed by the legal text and its constitutionality. In regard to the civil union of individuos of the same sex, the Court could not deduce that such union was implied by Law, like the interpretation according to the Constitution given by judges, on grounds of semantic purviews of the words man and woman, existents in both articles. The Court could not created it either, exceeding the legal system role. So, upon the institute creation, the STF, exceeded two limits: the interpretation and Law enforcement.

In marmosets, it was observed that the synchrony among circadian activity profiles of animals that cohabite in family groups is stronger than those of the same sex and age of different families. Inside the group, it is stronger between the younger ones than between them and their parents. However, the mechanisms involved in the social synchrony are unknown. With the aim to investigate the synchronization mechanisms involved in the synchrony between the circadian activity profiles during cohabitation in pairs of marmosets, the motor activity was continuously registered by the use of actmeters on three dyads. The pairs were maintained in two different conditions of illumination: light-dark cycle LD 12:12 (LD cohabitation I – 21 days), and thereafter in LL (~350 lux). Under LL, the pairs were submitted to four experimental situations: 1. Cohabitation (LLJ I – 24 days), 2. Removal of one member of the pair to another room with similar conditions (LLS I – 20 days), 3. Reintroduction of the separated member in the cage of the first situation (LLJ II – 30 days) and 4. Removal of a member from each pair to another experimental room (LLS II – 7 days), to evaluate the mechanisms of synchronization. Ultimately, the members of each pair were reintroduced in the cage and were kept in LD cycle 12:12 (LDJ II – 11 days). The rhythms of pairs free-ran in LL, with identical periods between the members of each pair during the two stages of cohabitation. In the stages in which the animals were separated, only the rhythms of two females free-ran in the first stage and of three animals in the second one. In those conditions, the rhythms of animals of each pair showed different endogenous periods. Besides, during cohabitation in LD and LL, the members of each pair showed a stable phase relationship in the beginning of the active phase, while in the stages in which the animals were separated it was noticed a breaking in the stability in the phase relationships between the circadian activity profiles, with an increase in the difference in the phase angles between them. During cohabitation, at the transition between LD and LL, all animals showed free-running rhythms anticipating progressively the beginning and the end of the active phase in a phase similar to the previous condition, showing signs of entrainment to the previous LD. While in the posterior stages this was observed in only three animals between: LLT I and LLS I, and LLT II and LLS II, evidencing signs of entrainment to social cues between the members of each pair. On the other hand, one animal delayed progressively between LLT I and LLS I, three animals delayed between LLS I and LLT II, and three animals between LLT II and LLS II, perhaps by entrainment to the animals maintained outdoors in the colony. Similar process was observed in four animals between LLS II and LDT II, indicating entrainment to LD. In the transition between LLS I and LLT II, signs of masking was observed in the rhythm of a female in response to the male and in another pair in the rhythm of the male in regard to that of the female. The general and maximum correlations in the circadian activity profiles were stronger during cohabitation in LD and LL than in the absence of social contact in LL, evidencing the social effect. The cohabiting pairs had higher values of the maximum correlation in LD and LL than when the profiles were correlated to animals of different cages, with same or different sexes. Similar results were observed in the general correlation. Therefore, it is suggested that cohabitation induces a strong synchrony between circadian activity profiles in marmosets, which involves entrainment and masking. Nevertheless, additional studies are necessary to evaluate the effect of social cues on the synchronization of the circadian rhythm in pairs of marmosets in the absence of external social cues in order to confirm this hypothesis.

This qualitative study explored the rural to urban migration’s effect and its related factors on later life health status and health perception among Kazakh Chinese. The participants were same sex sibling pairs, of which one moved from rural to urban areas in early life and the other stayed in rural areas. Rural participants tend to have more selected chronic diseases conditions and other self-reported conditions than urban participants but less physical limitations in older age. There is no clear difference on the health perceptions between rural and urban participants. Health care access and environmental factors are the major differences that may affect health in later life for rural participants.

Sexual fluidity has been proposed as a key component of women’s sexuality. However, not all women acknowledge or experience fluidity in their sexual attractions and behaviors. Because this is the case, what proportion of women are experiencing sexual fluidity? Research has concluded that a “sizeable minority” of women are experiencing sexual fluidity, with the highest levels found among those that identify as a sexual minority. Furthermore, certain individual differences have been found to be associated with a heightened (or weakened) likelihood of experiencing or embracing sexual fluidity. Through extensive literature reviews on women’s sexuality and sexual fluidity, it has been concluded that sexual orientation identity status, as well as psychological, biological, and social factors, all play roles in the expression or degree of sexual fluidity experienced. This means that certain personal and environmental factors have the ability to both hinder and/or nurture fluidity in a woman’s sexual attractions, behaviors, and experiences. Accepting that women’s sexuality is fluid and teaching about the variability sometimes observed in women’s sexuality allows us to not only see that experiencing same-sex attractions, desires, or experiences is not necessarily abnormal, but also that it may be more common than originally assumed, which has the potential to reduce societal stigma associated with homosexuality.

Algumas pesquisas demonstram que a presença de um parceiro social durante uma situação de risco modula a resposta ao estresse, atenuando seus efeitos negativos. Neste estudo, 8 díades de machos e 8 de fêmeas de sagüi comum (Callithrix jacchus) foram expostos a um ambiente novo, sozinhos e acompanhados de um parceiro de mesmo sexo e idade. Quando submetidos a um ambiente novo em companhia de um animal de mesmo sexo, os machos apresentaram um perfil mais filiativo enquanto as fêmeas foram mais competitivas entre si. Os resultados mostram que a resposta comportamental é sexualmente dimórfica, e que machos e fêmeas utilizam diferentes estratégias quando confrontados com situações desafiadoras no ambiente natural Abstract Some researches demonstrate that the presence of a social partner during a challenging situation modulates the stress response, decreasing its negative effects. In this study common marmoset (Callithrix jacchus) males and females were exposed to a new environment, alone or in companion of a social partner of the same sex and age. When submitted to new environment in companion of a same-sex social partner males showed more affiliation whereas females performed agonistic behaviors. The results show that behavioral response is sexually dimorphic and that males and females used different strategies when facing challenging situations in natural conditions

Mixing ages in school classes became more and more common during the last dec-ades of the 20th century. From being a way to organise classes out of necessity they have now come to be something which is implemented on the basis of pedagogical arguments. The aim of this research has been to improve our knowledge of classes where pupils are not of the same age. A study of the pupils’ perspectives has been my main interest. (Age) homogeneous class can been looked upon as a result of the authorities’ deci-sion to have a fixed age for children to start school and their decision that certain courses should be completed within a defined period of time. Terms and the data concerning heterogeneous age groupings are ambiguous and cannot be fully understood without knowledge of national and sometimes even local contexts. Practices within age heterogeneous classes may differ greatly. A great deal of individual work takes place in age heterogeneous classes. Whether the class is non-mixed or mixed-aged does not seem to have a major im-pact on cognitive or non-cognitive abilities among the pupils, but there are suggestions that age heterogeneous classes might be disadvantageous to pupils in problematic situations. I am able to show that more than 30% of pupils in grades 1-3, close to 25% in grades 4-5, about 15% in grade 6 and a couple of percent of Swedish pupils in the later school years are taught in mixed-age groups. My own empirical research focuses on pupils’ experiences. My investigation has a ‘life-world’ oriented approach inspired by phenomenology. Pupils in grades 5 and 6 from three schools in three different socio-economic settings were interviewed. These pupils had experienced both mixed-age and single-age classes. The life-world of pupils seems to be something different from that encompassed by the philosophy about the advantages of mixing the ages in classes. Pupils find it diffi-cult to maintain or create relationships when only a few pupils of the same sex, who have started school at the same time, can be together in a class for a long time. Be-cause of the importance of social relationships almost every pupil in this investigation wished to be in a single-age class during the following year. It is the importance of common experiences rather than age that is central. Pupils stated that having things in common to study in their everyday schoolwork makes it easier to communicate and contributes to stable friendships. In my conclusion I focus on what it means to have relationships and how these are important for human identity. I also try to show how relationships are important in learning situations at school and for pupils’ opportunities to expand their knowledge.
