A review of the scientific literature gives evidence that transferring previously single-caged adult macaques to permanent compatible pair-housing arrangements (isosexual pairs, adult/infant pairs) is associated with less risk of injury and morbidity than transferring them to permanent group-housing arrangements. Juvenile animals can readily be transferred to permanent group-housing situations without undue risks. Safe pair formation and subsequent pair-housing techniques have been developed for female and male rhesus (Macaca mulatta), stump-tailed (M. arctoides) and pig-tailed macaques (M. nemestrina) as well as for female long-tailed macaques (M. fascicularis). Pair housing does not jeopardize the animals’ physical health but it increases their behavioural health by providing them with an adequate environment to satisfy their need for social contact and social interaction.

This study examined the effects of social housing manipulations on bodyweight, corticosterone levels, and performance of T-maze alternation in male CD-1 mice. Males that adopted a dominant social rank were heavier than those that adopted a subordinate social rank. Dominant males also had lower corticosterone concentrations than the subordinates. However, there was little to suggest that these physiological indicators of social rank were moderated by housing condition. Indeed, statistical analysis confirmed that the difference in bodyweights was evident before males were socially housed. The mice showed high levels of spatial alternation on the T-maze from the start of testing so performance accuracy was high. Neither social rank nor housing condition had any clear categorical effect on T-maze performance. However, performance did fluctuate over successive blocks of testing and there was a negative association between accuracy on the T-maze and corticosterone levels (consistent with performance impairment because of elevated corticosterone). Therefore, under present conditions, individual differences in corticosterone were a better predictor of T-maze performance than social rank or housing condition. The results of the present study lend further support to the proposition that corticosterone levels measured non-invasively in urine may be used to predict diverse welfare outcomes for laboratory mice, from bodyweight to cognitive performance. Moreover, intrinsic physiological parameters rather than external influences, such as social housing, may have more influence on mouse behaviour.

Bodyweight is an important health and welfare indicator for captive non-human primates (NHPs). Bodyweight can be measured during routine handling procedures, which cause stress. Alternatively, animals can be trained to step onto a scale, but training success varies greatly between individuals. Being able to weigh animals regularly without having to handle or train them is thus desirable for monitoring animal health and welfare. This study investigates the utility, ie the participation, reliability and time investment, of voluntary weighing in captive NHPs living in large social groups. Subjects of the study were 92 rhesus macaques (Macaca mulatta) housed in four social groups at the Biomedical Primate Research Centre in Rijswijk, The Netherlands. A scale was placed in their home enclosure during several sessions. Individuals were unwilling to step onto an unbaited scale. When likeable food items were used to attract individuals to the scale, 68% of them stepped onto the scale. Age and dominance rank did not affect stepping onto the scale, whereas exploratory tendency and social group did. The level of agreement between bodyweight by voluntary weighing and bodyweight measured during sedation was very high. These results show that the majority of rhesus macaques in social groups can be weighed voluntarily and that voluntary weighing is reliable. When optimising and further developing the method, voluntary weighing can form a valuable tool in the captive management of NHPs.

Refinement of social housing practices is paramount to improving animal welfare in laboratory environments, especially with regard to non-human primates. Even though social housing of the same species should be considered the optimal paradigm, cynomolgus (Macaca fascicularis) and rhesus macaques (Macaca mulatta) share similar communication styles making inter-species, opposite sex socialisation a viable approach to providing social enrichment. This paper describes social housing a male cynomolgus macaque, which underwent a routine orchiectomy prior to pairing, with a female rhesus macaque for the purpose of providing social interaction for animals that otherwise would have been single housed. Once paired, the primates exhibited behaviours indicative of compatibility, including mounting, lip smacking, grooming, co-threatening and choosing to remain in close proximity. Social housing also ameliorated abnormal behaviour (eg pacing, self-directed fur-plucking) in the female macaque. Neutering male macaques, mixed-species pairing and opposite sex socialisation are all valid options for reducing the number of individually housed primates in research facilities.

Community support services are an integral enabler of aging in place. In social housing, older adult tenants struggle to access these services because of the siloed nature of housing and health services. This study examined the provision of government-funded community support services to 83 seniors’ social housing buildings in Toronto, Ontario. Although there were 56 different agencies operating within the buildings, only about one third of older tenants were actually receiving services. There was a subset of services that were available in more than 80 per cent of the buildings, and the most widely accessed services were food supports, crisis intervention, transportation, caregiver support, and hearing/vision care. There were also many cases in which multiple agencies offered duplicative services within the same building, suggesting that there are opportunities for improving service coordination. Practice recommendations for increasing access to community support services among low-income older adults in social housing are provided.

Does benefit competition affect voters' support for immigrants' social rights? While scholars in political economy expect that benefit competition lowers support among the poor, the evidence is limited. This seems to be largely due to the reliance on highly aggregated analyses and the neglect of the institutional context in which individuals form their preferences. This article argues that lower-income voters are more likely to reduce their support due to competition when benefit eligibility depends on income. Using individual-level panel data from the Netherlands and a novel way to measure benefit competition, the study shows that lower-middle-income voters become less supportive of immigrants' social rights when more social housing in their municipality is allocated to refugees. By contrast, competition does not reduce support among the rich or the very poor. The findings suggest that benefit competition can erode support for immigrants' social rights and influence electoral politics.

The Localism Act 2011 granted social landlords in England the right to award fixed-term (flexible) tenancies, thereby ending the right of new tenants to a secure tenancy. Reform was justified via reference to a revisionist critique of social housing, which accused security of tenure of promoting dependency, undercutting social mobility and preventing the effective operation of the sector as a welfare service. This article draws on empirical evidence from qualitative interviews with more than 140 social tenants to explore the legitimacy of these claims and consider the potential impact of ending security of tenure on the well-being of tenants. Analysis reveals security of tenure to be a source of stability that helps mediate the precariousness of life on low incomes. In conclusion, it is argued that policy should be looking to extend, rather than curtail, these benefits through an improved rental housing offer.
