The behavioural composition of a group and the dynamics of social interactions can both influence how social animals work collectively. For example, individuals exhibiting certain behavioural tendencies may have a disproportionately large impact on the group, and so are referred to as keystone individuals, while interactions between individuals can facilitate information transmission about resources. Despite the potential impact of both behavioural composition and interactions on collective behaviour, the relationship between consistent behaviours (also known as personalities) and social interactions remains poorly understood. Here, we use stochastic actor-oriented models to uncover the interdependencies between boldness and social interactions in the social spider Stegodyphus dumicola . We find that boldness has no effect on the likelihood of forming social interactions, but interactions do affect boldness, and lead to an increase in the boldness of the shyer individual. Furthermore, spiders tend to interact with the same individuals as their neighbours. In general, boldness decreases over time, but once an individual's boldness begins to increase, this increase accelerates, suggesting a positive feedback mechanism. These dynamics of interactions and boldness result in skewed boldness distributions of a few bold individuals and many shy individuals, as observed in nature. This group behavioural composition facilitates efficient collective behaviours, such as rapid collective prey attack. Thus, by examining the relationship between behaviour and interactions, we reveal the mechanisms that underlie the emergence of adaptive group composition and collective behaviour.

This article examines aspects of the relationship between the Norfolk poor and the Norfolk clergy between 1815 and 1914. It considers the potential impact clergymen could have upon a number of areas of secular life, especially with regard to the extirpation of popular culture and custom, the social and moral management inherent in charity and Poor Law administration, and the development of ‘power networks’ in the countryside that confronted the challenge posed by religious Nonconformity and political radicalism. The article is principally concerned with the importance of the Church of England as an instrument of secular authority in nineteenth-century rural life. Rival social structures and conflicting economic interests are subjected to both quantitative and qualitative analysis, while keys to cultural tension are sought in such iconic areas as the pageantry of parish entertainments; the re-casting of law to act against custom; the rise of the clergyman as antiquarian historian and amateur archaeologist; the symbolism and architecture of the restored church. In so doing an attempt is made to address questions that are at once broadly political and narrowly human in their scope. What did the Oxbridge scholar – perhaps having spent the preceding three years conversing in Greek and Latin with his peers – find to ‘say’ to the agricultural labourers now in his pastoral care? And why, when the clergyman (often justifiably) thought of himself as working unstintingly in his parishioners' interests, was he so often heartily despised by them?

Many of humans' most important social interactions rely on trust, including most notably among strangers. But little is known about the evolutionary roots of human trust. We presented chimpanzees ( Pan troglodytes ) with a modified version of the human trust game—trust in reciprocity—in which subjects could opt either to obtain a small but safe reward on their own or else to send a larger reward to a partner and trust her to reciprocate a part of the reward that she could not access herself. In a series of three studies, we found strong evidence that in interacting with a conspecific, chimpanzees show spontaneous trust in a novel context; flexibly adjust their level of trust to the trustworthiness of their partner and develop patterns of trusting reciprocity over time. At least in some contexts then, trust in reciprocity is not unique to humans, but rather has its evolutionary roots in the social interactions of humans' closest primate relatives.

In the long run economic growth does not improve people's well-being. Traditional theories – adaptation and social comparisons – explain this evidence, but they don't explain what shapes the trend of subjective well-being and its differences across countries. Recent research identified in social capital a plausible candidate to explain the trends of well-being. This dissertation adopts various econometric techniques to explore the relationship over time among social capital, economic growth and subjective well-being. The main conclusion is that social capital is a good predictor of the trend of subjective well-being, both within and across countries. Hence, policies for well-being should aim at preserving and enhancing social capital for the quality of the social environment matters.

AbstractCrowdsourcing is an emerging tool for collaboration and innovation platforms. Recently, crowdsourcing platforms have become a vital tool for firms to generate new ideas, especially large firms such as Dell, Microsoft, and Starbucks, Crowdsourcing provides firms with multiple advantages, notably, rapid solutions, cost savings, and a variety of novel ideas that represent the diversity inherent within a crowd. The literature on crowdsourcing is limited to empirical evidence of the advantage of crowdsourcing for businesses as an innovation strategy. In this study, Starbucks’ crowdsourcing platform, Ideas Starbucks, is examined, with three objectives: first, to determine crowdsourcing participants’ perception of the company by crowdsourcing participants when generating ideas on the platform. The second objective is to map users into a community structure to identify those more likely to produce ideas; the most promising users are grouped into the communities more likely to generate the best ideas. The third is to study the relationship between the users’ ideas’ sentiment scores and the frequency of discussions among crowdsourcing users. The results indicate that sentiment and emotion scores can be used to visualize the social interaction narrative over time. They also suggest that the fast greedy algorithm is the one best suited for community structure with a modularity on agreeable ideas of 0.53 and 8 significant communities using sentiment scores as edge weights. For disagreeable ideas, the modularity is 0.47 with 8 significant communities without edge weights. There is also a statistically significant quadratic relationship between the sentiments scores and the number of conversations between users.

To navigate through a social world, animals may form temporary or long-term associations with others, recognize kin and discriminate between familiar and unfamiliar conspecifics, protect themselves and their resources, fight and compete for the best mates, and produce offspring that require various forms of care. The purpose of the current paper was to summarize the publication trends of research investigating animal social interactions over the last 20 years. We selected 8 journals for their diverse representation of animal taxa and examined the number of published articles representing research on affiliative, agonistic, and sexual social interactions. Out of 18,993 published articles, social interactions (N = 4,273) were studied 5.5% to 30.8% of the published articles per journal between 1993-2013. Agonistic social interactions (43%) were the most frequently published topic with affiliative social interactions representing less than a third (30%) of the articles and sexual social interactions accounting for the remaining articles (27%). Mammalian social interactions were investigated the most (38.5%) with invertebrate (22%) and avian (21%) social interactions following closely behind. Observational research and experimental research designs were divided almost equally across different social interactions except for affiliative interactions. Social interactions were studied most often in laboratory settings (45%), then semi-natural field settings (32.5%), and less often in natural habitats (19%). Interestingly, the rates of the different types of social interactions, certain taxa, type of research study, and research setting remained relatively consistent across the 20 year period. Some fluctuations occurred in the frequency of specific topics and taxa within various years; however, research on mate choice, parental care, environmental influences, and group composition was consistently conducted across the years. While many aspects of social interactions in a broad range of taxa have been studied, there are many areas that are still sparse and in need of additional research.

SummaryCanadian courts are approaching the task of mediating the relationship between international law and domestic law with newfound energy. Yet, for all their declared openness to international law, courts are still inclined to avoid deciding cases on the basis of international law. This does not mean that international law is given no effect or that its broad relevance is denied. The avoidance strategy is more subtle: even when they invoke or refer to international law, Canadian courts generally do not give international norms concrete legal effect in individual cases. Although international law is brought to bear on a growing range of questions, its potential impact is tempered — and we fear largely eviscerated — because it is merely one factor in the application and interpretation of domestic law. Within the Canadian legal order the question of “bindingness” of international law is closely intertwined with the manner in which it comes to influence the interpretation of domestic law. In the case of norms that are binding on Canada under international law, Canadian courts have an obligation to interpret domestic law in conformity with the relevant international norms, as far as this is possible. By contrast, norms that do not bind Canada internationally (for example, soft law or provisions of treaties not ratified by Canada) can help inform the interpretation of domestic law and, depending on the norm in question and the case at issue, may even be persuasive. Courts may, and in some cases should, draw upon such norms for interpretative purposes, but they are not strictly speaking required to do so. However, especially following the Supreme Court’s decision inBaker, there appears to be a trend towards treating all of international law, whether custom or treaty, binding on Canada or not, implemented or unimplemented, in the same manner — as relevant and perhaps persuasive, but not as determinative, dare we say obligatory. Our concern is that if international law is merely persuasive, it becomes purely optional, and can be ignored at the discretion of the judge. We argue that it is not enough to treat all normative threads in this fashion — over time this approach risks weakening the fabric of the law.

A Star Is Born: The Relationship Between Performance and Achieving Status Through Certification Contests in the Context of Equity Analysts

Over Time

We investigate how the relationship between status and performance decouples over time by addressing two questions: (1) how performance affects the likelihood that an actor achieves high status and (2) how achieving high status affects the actor’s subsequent performance. In doing so, we focus on the role repeated certification contests play, where evaluators assess actors’ performance along particular dimensions and confer high status on the contest winners. Using the context of sell-side (brokerage) equity analysts and the “All-Star” list from Institutional Investor magazine, we first investigate whether analysts who make the All-Star list are more likely to produce accurate and/or independent forecasts. Then, we investigate analyst performance after recent and multiple wins. Our results demonstrate the decoupling of status and performance over time and the roles played by both the high-status actor and the social evaluators conferring their status. Whereas analyst performance increases the likelihood of being designated an All-Star, recent and multiple All-Star designations differentially affect both how subsequent performance is assessed, and how the All-Star analysts subsequently perform. In the short term, achieving high status can increase performance and solidify an analyst’s status position; however, in the long term, it can lead to lower performance and eventually result in status loss, which further erodes performance.

This chapter draws on the analysis in the previous chapters to illustrate how the courts’ conception of the relationship between law and social practices influences approaches to employment status and, relatedly, the effectiveness of labour law when it comes to securing or coordinating the provision of a ‘social wage’. It does this through the lens of the concept of ‘mutuality of obligation’. The first section explores the concept of ‘mutuality of obligation’ as it is conceived today. The second section then traces the development of this concept over time. The third section concludes with some observations about how the conception of law’s ontology we find implicit in the case law relates to the so-called ‘crisis’ we see today in labour law’s personal scope.

Cross-sector collaborative organizations are increasingly viewed as an effective means of addressing multifaceted health and social challenges. Given their dependence on volunteers to develop and implement strategy, members’ perceptions of future strategic priorities is a critical concern for leaders and sponsors of these organizations. Research set in more hierarchical, single-sector organizations acknowledges the important relationship between structure and strategy; however, relatively little research has explored these relationships in the context of collaborative organizations. We examined these relationships using multiple rounds of an Internet survey. All three dimensions of social structure (locus of decision making, formalization, and integration) had independent associations with participant’ perceptions of different strategic priorities, suggesting there is more than one approach to influencing the perceived priorities of the alliance. However, some dimensions of the social structure changed more than other dimensions over time, highlighting differential opportunities for influencing strategic priorities.

Social associations with conspecifics can expedite animals' acclimation to novel environments. However, the benefits gained from sociality may change as the habitat becomes familiar. Furthermore, the particular individuals with whom animals associate upon arrival at a new place, familiar conspecifics or knowledgeable unfamiliar residents, may influence the type of information they acquire about their new home. To examine animals' social dynamics in novel habitats, we studied the social behaviour of African elephants ( Loxodonta africana ) translocated into a novel environment. We found that the translocated elephants' association with conspecifics decreased over time supporting our hypothesis that sociality provides added benefits in novel environments. In addition, we found a positive correlation between body condition and social association, suggesting that elephants gain direct benefits from sociality. Furthermore, the translocated elephants associated significantly less than expected with the local residents and more than expected with familiar, but not necessarily genetically related, translocated elephants. The social segregation between the translocated and resident elephants declined over time, suggesting that elephants can integrate into an existing social setting. Knowledge of the relationship between sociality and habitat familiarity is highly important in our constantly changing world to both conservation practice and our understanding of animals' behaviour in novel environments.
