Biochemical Assessment

The neurohormone oxytocin is known to exert a special function in the regulation of social relationships throughout vertebrate taxa. Recently it has been discovered that not only within-species, but in certain cases, between-species social bonds are also mediated by the same hormone, e.g. in case of the dog�human relationship. However, despite the exponential growth of findings at the behavioural level, there are still a lot of controversies on the biochemical assessment of oxytocin in canine samples. Thus, in the current study we replicate previous findings of canine serum oxytocin increase following a positive dog�human interaction. We provide a detailed description of both the immunoassay method used as well as the behavioural protocol (including crucial time-parameters). This will serve as a base for further studies that both our group as well as others in the field will conduct.

Insight Into

The novel Second Thoughts deals with the story of a young middle class Bengali girl who marries a Bombay based foreign returned Bengali Boy. The story depicts the disillusionment of a married woman and an explosive tale of love and betrayal that exposes the hollowness of human relationship especially within arranged marriages. This chapter deals with the concept of Micro-Politics which is a significant dogma of postfeminism. Micro-Politics believes that there has been drastic change in the position of women in basic social relationships, within the families, workplace and other public spheres. Postfeministic notion of micro-politics is intended to provide insight into the complicated nexus of relationship and also to rethink this same concept in terms of postfeminism.

The Relationship

Most primates are intensely social and spend a large amount of time servicing social relationships. The social brain hypothesis suggests that the evolution of the primate brain has been driven by the necessity of dealing with increased social complexity. This chapter uses social network analysis to analyse the relationship between primate group size, neocortex ratio and several social network metrics. Findings suggest that social complexity may derive from managing indirect social relationships, i.e. relationships in which a female is not directly involved, which may pose high cognitive demands on primates. The discussion notes that a large neocortex allows individuals to form intense social bonds with some group members while at the same time enabling them to manage and monitor less intense indirect relationships without frequent direct involvement with each individual of the social group.

Several species mitigate relationships according to their conspecifics' parasite status. Yet, this defence strategy comes with the costs of depriving individuals from valuable social bonds. Animals therefore face a trade-off between the costs of pathogen exposure and the benefits of social relationships. According to the models of social evolution, social bonds are highly kin-biased. However, whether kinship mitigates social avoidance of contagious individuals has never been tested so far. Here, we build on previous research to demonstrate that mandrills ( Mandrillus sphinx ) modulate social avoidance of contagious individuals according to kinship: individuals do not avoid grooming their close maternal kin when contagious (parasitized with oro-faecally transmitted protozoa), although they do for more distant or non-kin. While individuals' parasite status has seldom been considered as a trait impacting social relationships in animals, this study goes a step beyond by showing that kinship balances the effect of health status on social behaviour in a non-human primate.

ABSTRACT This study provides new insights about how tax professionals' economic and social relationships with clients separately and jointly affect tax professionals' propensity to recommend aggressive tax positions to clients when resolving ambiguous issues. In an experiment with 133 practicing tax professionals, we manipulate the economic importance of the client and client identification (a social construct). We find that as the economic importance of the client increases, professional recommendations follow an inverted U-shaped pattern. Tax professionals more strongly recommend aggressive positions for clients of moderate economic importance than for clients of low or high economic importance. We also find that tax professionals with high versus low client identification provide more aggressive recommendations for clients of low or moderate economic importance, but not for clients of high economic importance. This paper contributes to the literature by identifying a boundary condition on client identification that has not been considered in prior accounting research.

This chapter examines Guédiguian’s youth in l’Estaque, a “communist” neighbourhood of Marseille, his political activism, his transition away from the Communist party, and finally a turn toward friendship as a figure for human interaction. The chapter examines the history of l’Estaque. It tells of Guédiguian’s friendship with Gérard Meylan, his meeting Ariane Ascaride, and then his disillusion with the Communist party, corresponding with his entry into filmmaking, but filmmaking that is not so much an industry or an art form as a way of “remaining with friends” through shared activity and cooperation. The chapter turns to the philosophy of friendship since Aristotle to ground this move in what Aristotle calls “eudaimonia” or the flourishing life. From there it discusses the political implications of a human relationship built on philia in a cultural period, our own, in which different figures of human interaction, the figures of the consumer and the entrepreneur are dominant. It concludes with a discussion of how Guédiguian’s cinema offers a way forward to those who have felt politically alienated during a period of economic “neoliberalism.”

AbstractHumans maintain extensive social ties of varying preferences, providing a range of opportunities for beneficial cooperative exchange that may promote collective action and our unique capacity for large-scale cooperation. Similarly, non-human animals maintain differentiated social relationships that promote dyadic cooperative exchange, but their link to cooperative collective action is little known. Here, we investigate the influence of social relationship properties on male and female chimpanzee participations in a costly form of group action, intergroup encounters. We find that intergroup encounter participation increases with a greater number of other participants as well as when participants are maternal kin or social bond partners, and that these effects are independent from one another and from the likelihood to associate with certain partners. Together, strong social relationships between kin and non-kin facilitate group-level cooperation in one of our closest living relatives, suggesting that social bonds may be integral to the evolution of cooperation in our own species.

Social animals often form long-lasting relationships with fellow group members, usually with close kin. In primates, strong social bonds have been associated with increased longevity, offspring survival and reproductive success. However, little is known about the fitness effects of social bonds between non-kin, especially outside of mammals. In this study, we use long-term field research on a cooperatively breeding bird, the greater ani ( Crotophaga major ), to ask whether adult females benefit by remaining in long-term associations with unrelated, co-breeding females. We find that females that have previously nested together synchronize their reproduction more rapidly than those nesting with unfamiliar partners, which leads to lower competition and higher fledging success. Importantly, although previous experience with a co-breeding female influenced reproductive synchrony, the degree of reproductive synchrony did not influence whether co-breeding females remained together in subsequent years, ruling out the alternate hypothesis that highly synchronized females are simply more likely to remain together. These results indicate that switching groups is costly to females, and that social familiarity improves reproductive coordination. Stable social relationships therefore have significant fitness consequences for cooperatively nesting female birds, suggesting that direct benefits alone may favour the evolution of associations between non-relatives and contribute to long-term group stability.

Social bonds, here defined as strong, equitable and enduring social relationships, increase fitness in both male and female primates irrespective of their dispersal regime. Despite the benefits they carry for some, social bonds evolved more often among female than among male primates which is thought to be caused by the unsharable nature of males’ limiting resource, fertilizations. Here we present a structured review of variation in primate male social relationships, mating systems, and social organization. In addition to classical socio-ecological reasoning and recent models on the evolution of male coalitions, we consider the phylogenetic history of species living in multi-male groups and alternative evolutionary routes to male co-residency, which may constrain the evolution of male social bonds in some cases. We summarize our results in a conceptual framework that represents the effects of male contest competition within and between groups on male social organization, affiliation and cooperation. We conclude that male social bonds evolved as long-term alliances that gain their adaptive function in within group contests and, thus, that the evolution of male social bonds is driven by variation in within group contest competition. Between group contest competition may select for large male group size but in the end it is the narrow window of medium to low within group contest competition that promotes the evolution of political coalitions and thus is responsible for the rarity of social bonds among primate males.
