The mixing of unfamiliar sows usually results in fighting which determines relative social rank. In some situations aggression can be perpetuated and subordinate animals can suffer as a result of competition for resources such as feed and space. Although Moore et al (1993) suggested that newly introduced group members become fully integrated after 21 days there have been few studies which have examined the development of social interactions over the longer term. The aim of the experiment was to determine how social behaviour changed over time and the affects that this may have on the welfare of group-housed sows.

Abstract The aim of this study was to recognize features determining social hierarchy in Wrzosówka Polska ewes kept indoors as well as to investigate their resting place and companionship preferences. Observations (156 hours in total) were carried out in a group of 22 ewes. The social rank of sheep was determined by their age, body weight and length of horns. Social position was positively correlated with aggressive behaviour performed and negatively with aggressive behaviour received. Use of space while resting was influenced by ewe social behaviour; aggressive individuals lied more often in attractive places, namely against walls and fodder troughs compared to other animals. In general, the ewes rested by having physical contact with animals of similar rank and aggressiveness. Kinship appeared not to be important in neighbour preference. As can be concluded, social interactions influenced the use of space and neighbourhood in ewes

AbstractFilial imprinting has become a model for understanding memory, learning and social behaviour in neonate animals. This fast attachment mechanism allows the young of precocial bird species to learn the characteristics of conspicuous visual stimuli and display affiliative response to them. Although more prolonged exposure to an object produces a stronger preference for it afterwards, this relation is not linear. Chicks can even prefer to approach novel rather than familiar objects at some stages of imprinting. The time course and stability of imprinting has just started to be investigated. To date, little is known about how filial preferences develop across time, due to the challenges in assessing individual performance. This study aimed to investigate filial preferences for familiar and novel imprinting objects over time. We have used an automated setup to track the behaviour of chicks continuously for subsequent days. After hatching, chicks were individually placed in an arena where stimuli were displayed on two opposite screens. The duration of exposure and the type of stimuli were manipulated while the time spent at the imprinting stimulus was monitored across six days. We showed that prolonged exposure (3 days vs 1 day) to a stimulus produced robust filial imprinting preferences. Interestingly, with a shorter exposure (1 day), animals re-evaluated their filial preferences in functions of their innate preferences and past experiences. Our study suggests that predispositions influence learning when the imprinting memories are not fully consolidated, driving animal preferences toward more predisposed stimuli.

Animal societies vary widely in the diversity of social behaviour and the distribution of reproductive shares among their group members. It has been shown that individual condition can lead to divergent social roles and that social specialisation can cause an exacerbation or a mitigation of the inequality among group members within a society. This work, however, has not investigated cases in which resource availability varies between different societies, a factor that is thought to explain variation in the level of cooperation and the disparities in reproductive shares within each social group. In this study, I focus on how resource availability mediates the expression of social behaviour and how this, in turn, mediates inequality both within and between groups. I find that when differences in resource availability between societies persist over time, resource-rich societies become more egalitarian. Because lower inequality improves the productivity of a society, the inequality between resource-rich and resource-poor societies rises. When resource availability fluctuates over time, resource-rich societies tend to become more unequal. Because inequality hinders the productivity of a society, the inequality between resource-rich and resource-poor societies falls. From the evolutionary standpoint, my results show that spatial and temporal variation in resource availability may exert a strong influence on the level of inequality both within and between societies.

The dual-strategies theory of social rank proposes that both dominance and prestige are effective strategies for gaining social rank (i.e., the capacity for influence) in groups. However, the only existing longitudinal investigation of these strategies suggests that, among undergraduate students, only prestige allows people to maintain social rank over time. The current study provides a longitudinal test of dominance and prestige in a context where dominance is more normative: MBA project groups. Among 548 MBA students in 104 groups, peer-rated dominance and prestige predicted gains in social rank over the course of 4 weeks, indicating that both strategies may help people not only gain social rank but also maintain it over time. Furthermore, prestige—but not dominance—led to social rank because of willingly given deference from group members. This confirms a central but thus-far-untested principle of dual-strategies theory: While prestige is based on freely conferred deference, dominance is not.

Abstract Social interactions are pervasive in human life with varying forms of interpersonal coordination emerging and spanning different modalities (e.g., behaviors, speech/language, and neurophysiology). However, during social interactions, as in any dynamical system, patterns of coordination form and dissipate at different scales. Historically, researchers have used aggregate measures to capture coordination over time. While those measures (e.g., mean relative phase, cross-correlation, coherence) have provided a wealth of information about coordination in social settings, some evidence suggests that multiscale coordination may change over the time course of a typical empirical observation. To address this gap, we demonstrate an underutilized method, windowed multiscale synchrony, that moves beyond quantifying aggregate measures of coordination by focusing on how the relative strength of coordination changes over time and the scales that comprise social interaction. This method involves using a wavelet transform to decompose time series into component frequencies (i.e., scales), preserving temporal information and then quantifying phase synchronization at each of these scales. We apply this method to both simulated and empirical interpersonal physiological and neuromechanical data. We anticipate that demonstrating this method will stimulate new insights on the mechanisms and functions of synchrony in interpersonal contexts using neurophysiological and behavioral measures.

Social behaviour in solitary carnivores has long been an active area of investigation but for many species remains largely founded in conjecture compared to our understanding of sociality in group-living species. The social organization of the wolverine has, until now, received little attention beyond its portrayal as a typical mustelid social system. In this chapter the authors compile observations of social interactions from multiple wolverine field studies, which are integrated into an ecological framework. An ethological model for the wolverine is proposed that reveals an intricate social organization, which is driven by variable resource availability within extremely large territories and supports social behaviour that underpins offspring development.

Contemporary Standard

This chapter examines the forms and usage of imperatives and command strategies in contemporary standard Japanese. Although commands are highly face-threatening acts in any language, speakers of Japanese encounter particular challenges in using them in socially acceptable ways. Commands are generally only given to those considered ‘below’ the speaker in the social hierarchy, and are normally considered appropriate only when used toward ‘in-group’ members. Further restrictions relate to the identity the speaker wishes to convey. Numerous command strategies have emerged to avoid using the most direct imperative forms, and some of these strategies have gradually come to be reinterpreted as imperative forms themselves, suggesting a loss of their original euphemistic qualities. Furthermore, when issuing commands, speakers often go to considerable lengths to soften the face threat, for example by giving reasons for the command, adding markers of hesitancy, or softening illocutionary particles, and using appropriate honorific language forms.

This largely descriptive chapter introduces the reader to the specific features and functions of each type of hostelry and provides a broad-brush picture of their historical development, activities, ways they influenced each other, and importance in their role in out-of-home consumption of food, drink, and sociality. It outlines their social, economic, and political functions, and places them in their societal context. The pub was always the lowest in the social hierarchy among the three. Yet, it has been the longest survivor and has gradually taken over some of the functions formerly performed by inns and taverns. Inns and taverns, however, persist in the British social imagination and, where their buildings have survived, they lend distinction to a village or part of town. Both continuities and changes over time, as well as some overlap between the three hostelries, are described using examples of places and personalities.

Prior research has found an association between pride experiences and social rank outcomes. However, the causal direction of this relationship remains unclear. The current research used a longitudinal design ( N = 1,653) to investigate whether pride experiences are likely to be a cause, consequence, or both, of social rank outcomes, by tracking changes in individuals’ pride and social rank over time. Prior research also has uncovered distinct correlational relationships between the two facets of pride, authentic and hubristic, and two forms of social rank, prestige and dominance, respectively. We therefore separately examined longitudinal relationships between each pride facet and each form of social rank. Results reveal distinct bidirectional relationships between authentic pride and prestige and hubristic pride and dominance, suggesting that specific kinds of pride experiences and specific forms of social rank are both an antecedent and a consequence of one another.

Neighbourhood places like shops, cafes and parks support a variety of social interactions ranging from the ephemeral to the intimate. Repeated interactions at neighbourhood places over time lay the foundation for the development of social cohesion and collective efficacy. In this study, we examine the proposition that changes in the presence or arrangement of neighbourhood places can destabilise social cohesion and collective efficacy, which has implications for crime. Using spatially integrated crime, social survey and parcel-level land-use classification data, we estimate mixed effects panel models predicting changes in theft and nuisance crimes across 147 Australian neighbourhoods. The findings are consistent with neighbourhood social control and crime opportunity theories. Neighbourhood development – indicated by fewer vacant properties and fewer industrial and agricultural sites – is associated with higher collective efficacy and less crime over time. Conversely, introducing more restaurants, transit stations and cinemas is associated with higher theft and nuisance over time regardless of neighbourhood collective efficacy. We argue that the addition of socially conducive places can leave neighbourhoods vulnerable to crime until new patterns of sociability emerge and collective efficacy develops.
