Abstract Many animals engage in sociosexual behaviour, including that between same-sex pairs. Bonobos (Pan paniscus) are famous for their sociosexual behaviour, but chimpanzees (Pan troglodytes) apparently do not engage in sociosexual behaviour frequently. However, sociosexual behaviour in chimpanzees may have been overlooked. We observed 584 instances of sociosexual behaviour in chimpanzees at Ngogo, Kibale National Park, Uganda during three years of study. All ages and sexes engaged in sociosexual behaviour, which included mounting, touching of genitals, and pressing genitals together. Most sociosexual behaviour was between adult males. Sociosexual behaviour was often during tense contexts, such as subgroup reunions and during territorial behaviour. Among males, grooming and dominance rank relationships do not explain patterns of sociosexual behaviour. Although sociosexual behaviour may be less frequent in chimpanzees than in bonobos, and bonobos remain distinct in their genito-genital rubbing, our findings suggest that sociosexual behaviour is a regular part of chimpanzee behaviour.

As more same-sex couples enter into civil unions and domestic partnerships, the courts and other institutions are beginning to consider the implications of these partnerships in several areas of the law. A Georgia appeals court, for example, recently published the first opinion addressing this issue, ruling that a civil union of two women, obtained in Vermont, was not equivalent to a marriage for the purposes of interpreting a child custody agreement entered into in Georgia. As many observers predicted, the enactment of legislation recognizing same-sex partnerships has profound implications on the practice of family law, trust and estate law and healthcare law.This Article focuses on an area of healthcare law in which the legal status of a civil union or domestic partnership could have significant consequences—organ donations. In particular, it explores whether a civil union or domestic partner is an appropriate party to consent to an organ donation.

Abstract Objectives We provide the first nationally representative population-based study of cognitive disparities among same-sex and different-sex couples in the United States. Methods We analyzed data from the Health and Retirement Study (2000–2016). The sample included 23,669 respondents (196 same-sex partners and 23,473 different-sex partners) aged 50 and older who contributed to 85,117 person-period records (496 from same-sex partners and 84,621 from different-sex partners). Cognitive impairment was assessed using the modified version of the Telephone Interview for Cognitive Status. Mixed-effects discrete-time hazard regression models were estimated to predict the odds of cognitive impairment. Results The estimated odds of cognitive impairment were 78% (p < .01) higher for same-sex partners than for different-sex partners. This disparity was mainly explained by differences in marital status and, to a much lesser extent, by differences in physical and mental health. Specifically, a significantly higher proportion of same-sex partners than different-sex partners were cohabiting rather than legally married (72.98% vs. 5.42% in the study sample), and cohabitors had a significantly higher risk of cognitive impairment than their married counterparts (odds ratio = 1.53, p < .001). Discussion The findings indicate that designing and implementing public policies and programs that work to eliminate societal homophobia, especially among older adults, is a critical step in reducing the elevated risk of cognitive impairment among older same-sex couples.

Purpose Quantitative research on the segregation of same-sex partners in the USA is new, and limited by challenges related to the accurate measurement of segregation and data errors. The purpose of this paper is to provide a novel approach to re-examine residential segregation between same-sex partners and different-sex partners in the USA. Design/methodology/approach Two versions of the dissimilarity index and corrected same-sex partners data from the 2010 decennial census were used. Effects of different geographic scales were examined. Findings Results reveal that the levels of segregation of both male and female same-sex partners were higher at metropolitan- vs state-levels; the levels of segregation was lower when measured using the unbiased as compared to the conventional version of the D-index; and male same-sex partnered households were more segregated from different-sex partnered households than were female same-sex partnered households. Research limitations/implications Future studies should be attuned to geographic scale effects and should not ignore the bias of the D-index. Originality/value This study provides a better test of the differences between the two versions of the D-index and contributes to the literature by examining the segregation of both male same-sex partners and female same-sex partners across different geographic scales.

Social integration and support can have profound effects on human survival. The extent of this phenomenon in non-human animals is largely unknown, but such knowledge is important to understanding the evolution of both lifespan and sociality. Here, we report evidence that levels of affiliative social behaviour (i.e. ‘social connectedness’) with both same-sex and opposite-sex conspecifics predict adult survival in wild female baboons. In the Amboseli ecosystem in Kenya, adult female baboons that were socially connected to either adult males or adult females lived longer than females who were socially isolated from both sexes—females with strong connectedness to individuals of both sexes lived the longest. Female social connectedness to males was predicted by high dominance rank, indicating that males are a limited resource for females, and females compete for access to male social partners. To date, only a handful of animal studies have found that social relationships may affect survival. This study extends those findings by examining relationships to both sexes in by far the largest dataset yet examined for any animal. Our results support the idea that social effects on survival are evolutionarily conserved in social mammals.

AbstractFrom 2000 to 2010, the segregation of male same-sex couples from different-sex couples declined in almost all of the nation’s largest cities. This trend toward a more even distribution of male same-sex couples across city neighborhoods calls into question the demographic future of gay neighborhoods. However, it is unclear how exactly male same-sex couples are spatially reorganizing within desegregating cities. Multiple processes could be driving declining segregation, including declining shares of same-sex households within gay neighborhoods, the emergence of gay neighborhoods in new parts of the city, and/or a general dispersal of same-sex couples to almost all neighborhoods. Moreover, it is unclear what characteristics—like urbanicity, housing values, or racial/ethnic composition—define neighborhoods that have gained (or lost) same-sex partners. This chapter uses data from the 2000 and 2010 Decennial Censuses to investigate neighborhood-level changes within desegregating cities. The small number of increasingly segregated cities are also explored. Results indicate that increasing representation of male same-sex households across most neighborhoods and an expanding number of gay neighborhoods are important contributors to the trend of declining segregation. In contrast, the loss of gay neighborhoods from a city was fairly uncommon—most neighborhoods that obtained large concentrations of same-sex partners tended to keep those concentrations over time. Finally, the same residential expansion of same-sex households that occurred within desegregating cities did not occur in cities that experienced increasing segregation. These results have important implications for the spatial organization of same-sex households into the future. The chapter concludes with a discussion and critique of census data for the continued study of the geography and segregation of same-sex partners.

The year 2008 by all means will be remembered by several events, which contributed to significant progress in the domain of legal recognition of various aspects of same sex communities. There were also several initiatives contributing to making the political will necessary for legal changes. The most visible one probably was the May recognition of same sex marriage by the Supreme Court of California, which was valid only 5 months before it was cancelled by the referendum held in November 2008. Since this American state has 38 million inhabitants, more than the whole Balkan region, the event was visible by the whole world. The paper provides further analysis of mostly European events, e.g. decisions of European courts in Strasbourg and Luxembourg, political interventions by the EU Parliament Intercrop, releases of the ILGA-Europe, gay pride marches, other public activities, e.g. exhibition in the EU Parliament regarding the International Day of Human Rights, adoption of various documents relevant for the EU member states and permanent changes in internal legal provisions of the member states. The UN Declaration against discrimination on the ground of sexual orientation and gender identity concluded the year. The paper also comprises analysis of a few typical cases of implementation of family relations among same sex partners.

Homosexual Marriage

The paper elaborates on the relation between marriage and the family, on one hand, and marriage-like and family-like homosexual unions such as so-called homosexual marriage and same-sex union (or same-sex life partnership). With a brief theoretical introduction and a comparative overview of the manner in which this matter is regulated in other countries, certain solutions are analyzed from the Proposal Draft Law on Same-Sex Unions of Serbia (2021). It is indicated that it is no longer possible to equalize marriage and the family with the same-sex union because the content of these concepts is substantially different. The society is interested in protecting marriage and the family and to take special care of them since they perform extremely important social functions, whereas without some of them the survival of the society itself would be brought to question (the reproduction function). On the other hand, homosexual marriage and/or same-sex unions do not perform any social function, but are formed exclusively for the purpose of relatively longer-standing satisfaction of sexual needs of same-sex partners. Since the society and the state do not protect marriage only because sexuality is regulated within it, but because it legitimizes sexual relationships aimed at having children, in the event of homosexual marriage-like unions it should also be proceeded in an identical manner: solely those rights and obligations of partners deriving from a relatively longer-standing homosexual partnership should be legally regulated. Moreover, having in mind the principle that every man's right is limited by other people's rights, it is impermissible to give priority to the protection of the rights of same-sex partners for the purpose of longer-standing homosexual relationships over the protection of children's rights. Children need both a father and a mother (an ideal condition), and the family in which they will be socialized. In line with those homosexual marriage-like unions, neither adoption nor assisted insemination can be allowed.
