Women are globally underrepresented as political leaders; as of January 2023, only 17 countries had a woman head of government. Included in this small group is Samoa, which elected Fiame Naomi Mata’afa as its first woman prime minister in 2021 after a fiercely contested election and subsequent protracted legal disputes centered around interpretations of Samoa’s 10% gender quota. Drawing on data from the Pacific Attitudes Survey, the first large-scale, nationally representative popular political attitudes survey conducted in the Pacific region, this article examines how the political environment in Samoa shapes opportunities for women’s political participation and leadership. Using the theoretical framework of cohabitation, it finds that although there is an enabling environment for women’s participation and leadership in formal politics, women’s access to decision-making spaces more broadly is still constrained by norms of traditional leadership. This speaks to traditional and nontraditional political norms and practices that coexist, at times uneasily, alongside one another.

It is well-known that marital status is an important predictor for life expectancy. However, non-married individuals are often misclassified as singles which ignores the heterogeneity within the group. This paper shows the importance of distinguishing between types of singles, and in particular whether they are cohabiting, when predicting life expectancies. We use unique and detailed longitudinal register data to track marital status throughout the individual's lifetime. We find that all types of singles consistently benefit from living with a spouse, i.e., after divorce, becoming widower or being never married. This result holds for both men and women. For certain types of cohabiting singles we reject significant differences in life expectancy compared to married individuals. Finally, we use a case study to show that, like married individuals, all types of singles that cohabit also serve as informal caregivers and have the potential to limit the end-of-life long-term care expenditure levels.

This article argues that marriage is a divine institution that pre-dates the state, and marriages are supernaturally effected by God consequent on the exchange of marital consent by the parties, whether or not the state recognises them as marriages. In fact, taking note of, and legislating about, marriage thus properly conceived is not within the state's remit. Despite this, the law in England and Wales is involved with the institution of marriage in three main ways: (1) it purports to define marriage, and its entry and exit conditions; (2) it passes laws affording or denying certain legal benefits or penalties on the basis of marital status; and (3) it registers marriages, and in practice imposes or denies the benefits or penalties just mentioned on the basis of registration of marriage, or lack of it. The supernatural action on God's part of creating marriages is not a fit subject for such involvement on the state's part. The underlying exchange of marital consent by the parties is, by contrast, within the state's sphere of competence, but it is argued that the state should be tracking a broader category of relationships than just those involving the exchange of marital consent. It is suggested that all marriage law should be repealed, and replaced by an Australian-style law of de facto relationships. If the law deals with de facto relationships there is no need for it to be involved with the institution of marriage as well, and that institution can be left to flourish outside the state's grasp. The article goes on to respond to some possible objections.

The study examined the argument that cohabitation as a form of union increases physical violence victimization among women. The study’s aim was to assess the association between physical violence and other socio-demographic factors that influence physical violence among women. Self-reported data were extracted from the 2016 Uganda Demographic and Health Survey (UDHS), with a sample of 2479 couples, from the couple file. Chi-squared tests and multivariate Firth-logit regression models were used to examine the relationship between intimate partner violence (IPV) victimization and marital status controlling for other social-demographic factors. There was no significant evidence that women in cohabiting union have a higher risk of exposure to physical violence in the Ugandan context. The risk of experiencing physical violence perpetration varied by birth cohort, with the most recent cohorts exhibiting a slightly higher risk of experiencing partner violence than previous cohorts. Significant factors found to be associated with an increased risk of experiencing IPV included being in the poorer, middle and richer compared with the poorest wealth tertile of income, residing in Eastern or Northern regions compared with the Central region, being affiliated to the Catholic faith compared with Anglican and having five or more children compared with 4 or fewer children. In conclusion, there is no evidence that physical violence is more pronounced among women in cohabiting unions compared with married women in Uganda.

Scholars have long noted that couples are more likely to vote compared to individuals who live alone, and that partners' turnout behavior is strongly correlated. This study examines a large administrative dataset containing detailed information about validated turnout and the timing of individuals moving in together, and finds evidence of a substantial and robust increase in turnout after cohabitation. The study exploits the fact that two-voter households moving in together right before an election are comparable to those moving in together right after the election. Depending on the model specification, turnout increases by 3.5 to 10.6 percentage points in the months after taking up cohabitation. Voters are mobilized regardless of their own and their cohabitant's turnout behavior in a previous election. The results are robust to several robustness checks, including benchmarking with singles who move to mitigate the cost of moving in the analysis. The results highlight the importance of social norms and the household's essential role as a proximate social network that increases turnout.

The Pacific oyster Crassostrea gigas contributes significantly to global aquaculture; however, C. gigas culture has been affected by ostreid herpesvirus-1 (OsHV-1) and variants. The dynamics of how the virus maintains itself at culture sites is unclear and the role of carriers, reservoirs or hosts is unknown. Both wild and cultured mussels Mytilus spp. (Mytilus edulis, Mytilus galloprovincialis and hybrids) are commonly found at C. gigas culture sites. The objective of this study was to investigate if Mytilus spp. can harbour the virus and if viral transmission can occur between mussels and oysters. Mytilus spp. living at oyster trestles, 400–500 m higher up the shore from the trestles and up to 26 km at non-culture sites were screened for OsHV-1 and variants by all the World Organization for Animal Health (OIE) recommended diagnostic methods including polymerase chain reaction (PCR), quantitative PCR (qPCR), histology, in situ hybridization and confirmation using direct sequencing. The particular primers that target OsHV-1 and variants, including OsHV-1 microVar (μVar), were used in the PCR and qPCR. OsHV-1 μVar was detected in wild Mytilus spp. at C. gigas culture sites and more significantly the virus was detected in mussels at non-culture sites. Cohabitation of exposed wild mussels and naïve C. gigas resulted in viral transmission after 14 days, under an elevated temperature regime. These results indicate that mussels can harbour OsHV-1 μVar; however, the impact of OsHV-1 μVar on Mytilus spp. requires further investigation.

As detailed knowledge on multigenerational migrant families is sparse, this paper draws on quantitative and qualitative data to investigate intergenerational co-residence for older Turkish immigrants in Denmark. Registry data show that 23 per cent of Turkish immigrants in the 65–74 years age group live in intergenerational households – a level halfway between levels in Denmark and Turkey. These extended households are predominantly of the ‘culturally ideal’ type – formed by sons, sons’ wives and often the couple's children. One in five extended households, however, includes unwed sons and hence do not provide access to the labour power of daughters-in-law. Many factors seem to contribute to the observed pattern, including variable meanings of intergenerational co-habitation, high levels of poverty and limited housing options for extended families. Interviews with older Turkish immigrants point to another contributing factor, namely men's difficulties finding wives willing to live with parents-in-law. The sons’ hardships in this regard can be tied to a Danish immigration regime that bars marriage migrants from entering into extended households. While Turkish women raised in Denmark do not face such legal restrictions, such young women may reject marriage proposals entailing in-law co-habitation. The study thus adds new nuances to our understanding of how the dynamics of age, gender and immigration experience may shape the ways in which older immigrants live in Europe today.

Few studies have focussed on the health and immunity of triploid Atlantic salmon and therefore much is still unknown about their response to commercially significant pathogens. This is important if triploid stocks are to be considered for full-scale commercial production. This study aimed to investigate and compare the response of triploid and diploid Atlantic salmon to an experimental challenge with Neoparamoeba perurans, causative agent of amoebic gill disease (AGD). This disease is economically significant for the aquaculture industry. The results indicated that ploidy had no significant effect on gross gill score or gill filaments affected, while infection and time had significant effects. Ploidy, infection and time did not affect complement or anti-protease activities. Ploidy had a significant effect on lysozyme activity at 21 days post-infection (while infection and time did not), although activity was within the ranges previously recorded for salmonids. Stock did not significantly affect any of the parameters measured. Based on the study results, it can be suggested that ploidy does not affect the manifestation or severity of AGD pathology or the serum innate immune response. Additionally, the serum immune response of diploid and triploid Atlantic salmon may not be significantly affected by amoebic gill disease.

Conservative welfare state policies as in Germany often presume that money is a common resource within couples and, therefore, pooled. Research, however, indicates that money is increasingly managed separately or partly separately. This trend is either explained by the diversification of forms of relationships or interpreted as a general decline of the joint pooling of money. Contributing to this debate, this study investigates whether couples abandon independent money management when particular life events occur or when partners’ resources change. Data from the German Socio-Economic Panel (SOEP) for the years 2004, 2005 and 2008 are used. Panel analyses show that marriage leads to joint pooling or partly independent money management. An increase in women's incomes, however, is associated with independent money management. Women's wish for independence apparently contributes to the decline of the joint pool. The substantial prevalence of financial independence within couples calls into doubt the adequacy of German welfare state policies.

This study presents the validation process of the Portuguese version of the short-form Dedication Scale (Rhoades, Stanley, & Markman, 2006; Stanley, 1986), with a sample of 924 participants in different relationship statutes. With 14 items, this short version is recommended by the authors for its simple use, when wanting to measure commitment in romantic relationships. Confirmatory factor analysis showed that the instrument did not have a totally acceptable fit with the data so an exploratory factor analysis was conducted. This revealed a one-dimensional structure of the scale, and led to the exclusion of two items, which relate to a distinct meta-commitment dimension. In sum, the Portuguese version (ECP - Personal Commitment Scale) has 12 items, with good internal consistency (α = .82), correlations item-total between .36 and .60, and good criteria validity (p < .001). Its use for research is therefore appropriate. In a second study, significant differences were found between the participants' four relationship statuses (dating non-cohabiting and cohabiting relationships, formal unions and marriage) (p < .001; η2 p = .03). Results showed that married participants were more committed than those in a formal union, even when controlling for several relational and socio-demographic variables. No differences were found between cohabiting and non-cohabiting dating participants. Men reported higher levels of commitment than women (p < .001; η2 p = .02). Implications and suggestions for future research are discussed.

Neither in England, nor in Germany, nor in all Canadian provinces, does the law provide specific rules for the redistribution of property for unmarried cohabitants after the breakdown of their relationship. Instead, courts apply the law of trusts, contract and unjust enrichment with an eye to the characteristics of intimate relationships, as, for example, in decisions like the English Jones v Kernott ([2011] UKSC 53) and the Canadian Kerr v Baranow (2011 SCC 10). This article compares English, Canadian, and German case law and evaluates it both from a doctrinal perspective and as a part of a general approach towards cohabitation. The article concludes with an appeal for legislative action that strikes the right balance between party autonomy and protection of the weaker party.

The article presents the main results of research carried out in the autumn of 1995 on a sample of 309 senior citizens, living at home and residing in the CLSC La Source area, a suburb of Quebec. The purpose of this research was to gather information on the horizontal solidarity phenomenon among senior citizens. Three points of analysis have been used to define the concept of horizontal solidarity: individual help, community life and living together. The study presents a profile of senior citizens firmly rooted in their community, rather active and having frequent social contacts with their relatives. It emphasized the importance of the family in maintaining the existing solidarity, especially when the individual is not self-sufficient. The results of the research challenge the popular myth which stipulates that senior citizens represent, in the community, a passive, socially-withdrawn group.

Most regions of the world support moth species that use caves as diurnal roosts and/or as overwintering and mating sites. Although subterranean roosts are often also occupied by insectivorous bats, nothing is known about moth–bat interaction at these sites. The frequency of cohabitation and the dynamics of moth–bat interaction at roosts were examined during surveys at 30 known bat roosts in eastern Australia; 15 disused mines and 15 natural caves. Moths and bats cohabited in 20 roosts (67%); however, only two species of eared moths, Speiredonia spectans and S. mutabilis (Noctuidae), were observed. These large (wingspan up to 75 mm) species show a classic escape response to ultrasound. Moths used roosts occupied by bats with both frequency modulated (FM) (four species) and constant frequency (CF) (two species) echolocation calls. Signal frequencies of these bats had ranges of 23–25 and 44–71 kHz. Moths were absent from roosts occupied by high-frequency (>140 kHz) CF bats. Predator–prey interaction was assessed by studying a sub-sample of six roosts occupied by S. spectans and the horseshoe bat Rhinolophus megaphyllus. Speiredonia spectans and R. megaphyllus cohabited roosts throughout the year. Bats captured and consumed moths in these roosts. The numbers of moth wings on the floor of roosts were counted to assess rates of predation. Bats consumed 209 moths at the six roosts over a 12-month period, representing 19% of the moth population at the start of the study. The study establishes that moth–bat cohabitation of roosts is relatively common in eastern Australia and that bats do capture moths in these sites. Bat predation seems to be a significant source of mortality of moths that occupy subterranean roosts.
