Many social groups are made up of complex social networks in which each individual associates with a distinct subset of its groupmates. If social groups become larger over time, competition often leads to a permanent group fission. During such fissions, complex social networks present a collective decision problem and a multidimensional optimization problem: it is advantageous for each individual to remain with their closest allies after a fission, but impossible for every individual to do so. Here, we develop computational algorithms designed to simulate group fissions in a network-theoretic framework. We focus on three fission algorithms (democracy, community and despotism) that fall on a spectrum from a democratic to a dictatorial collective decision. We parameterize our social networks with data from wild baboons ( Papio cynocephalus ) and compare our simulated fissions with actual baboon fission events. We find that the democracy and community algorithms (egalitarian decisions where each individual influences the outcome) better maintain social networks during simulated fissions than despotic decisions (driven primarily by a single individual). We also find that egalitarian decisions are better at predicting the observed individual-level outcomes of observed fissions, although the observed fissions often disturbed their social networks more than the simulated egalitarian fissions.

One is either on Facebook or not. Of course, this assessment is controversial and its rationale arguable. It is nevertheless not far, for many, from the reason behind joining social media and publishing and sharing details of their professional and private lives. Not only the personal details that may be revealed, but also the structure of the networks are sources of invaluable information for any organization wanting to understand and learn about social groups, their dynamics and members. These organizations may or may not be benevolent. It is important to devise, design and evaluate solutions that guarantee some privacy. One approach that reconciles the different stakeholders’ requirement is the publication of a modified graph. The perturbation is hoped to be sufficient to protect members’ privacy while it maintains sufficient utility for analysts wanting to study the social media as a whole. In this paper, the authors try to empirically quantify the inevitable trade-off between utility and privacy. They do so for two state-of-the-art graph anonymization algorithms that protect against most structural attacks, the k-automorphism algorithm and the k-degree anonymity algorithm. The authors measure several metrics for a series of real graphs from various social media before and after their anonymization under various settings.

AbstractFemale chacma baboons (Papio cynocephalus ursinus) in the Drakensberg mountains, experiencing neither predation nor within-group competition, structure their social relationships with other females in order to sustain reciprocated grooming (Henzi et al., 1997b). To do so, they cap, where time constraints demand, the size of their grooming cliques. From this we have assumed that the social orientation of mountain baboon females is primarily towards other females and that fission is a consequence of the increasing differentiation of cliques, leading to one or a few females following a male 'friend' when he departs. An alternative argument (Barton et al., 1996) is that, where predation or within-group competition do not occur, neither should female-bonded groups. In this view, females under such conditions should be 'cross-bonded' to males, each group male associating with a few females in the manner of hamadryas baboons (P. c. hamadryas). We test this prediction of 'cross-bonding' at both troop and individual level and find no evidence to support it. We then present data on fission events which argue for fission in the Drakensberg being due to the departure of small one-male units. However, the data do not support, unequivocally, the proposal that females leave with male 'friends'. They do, however, always leave with a male who has fathered at least one of their non-adult offspring.

AbstractWide adoption of mobile computing, smartphones, social networks and big data techniques have brought undoubtable advantages to society as such, as well as to its individuals. The downside of this diffusion of technology throughout society has already been well discussed. Single authors also pointed out the threats not only to the single individual, but to democratic society as a whole. However, suggestions or even practical approaches of how to mitigate these threats not only at the individual level (

UNDP’s 2030 agenda of Sustainable Development Goals (SDGs) emphasized gender equality in augmenting human capital and alleviating poverty. For eradication of extreme poverty and building resilience for persons who are vulnerable to poverty, SDGs calls for a pro-poor and gender-sensitive policy framework. In this context, a gender-based study on multi-dimensional aspects of poverty is highly significant. Extant literature reveals that females are more deprived in different dimensions of poverty such as education, health, living standard, empowerment, environment, autonomy and social relationship. The present study is conducted with the basic objective of examining feminization of poverty in rural areas of Jagatsinghapur district of Odisha. Seven socio-economic dimensions comprising sixteen indicators have been taken into consideration to construct the Multidimensional Poverty Index (MPI) using the Alkire-Foster (AF) Method at the individual level. The novelty of the study lies in analyzing MPI at the individual level for rural Odisha. Higher female deprivation is observed across social groups and all occupation categories except services. Dummy variable regression analysis also supports the major findings of the study. Complementary Cumulative Distribution Function satisfies strict first-order stochastic dominance condition and substantiates the feminisation of poverty at each level of poverty cut-off across all social groups and occupational categories except for services. The findings of the study have significant implications for developing suitable policies for gender equalization and poverty alleviation.

The purpose of the concluding chapter is to review and draw some conclusions from all that has been covered in previous chapters. To do so, it first summarizes the MacIntyrean virtue ethics approach, particularly at the individual level. It then reconsiders the organizational and managerial implications, drawing out some of the themes which have emerged from the various studies which have been explored particularly in Chapters 8 and 9. In doing so, the chapter considers a question which has been implicit in the discussions to this point: how feasible is all of this, particularly for organizations? In the light of that, it revisits the earlier critique of current approaches to organizational ethics (Corporate Social Responsibility and the stakeholder approach), before concluding.

Gendered Expectations

This is the first data chapter. In this chapter, respondents who are described as true believers in the gender structure, and essentialist gender differences are introduced and their interviews analyzed. They are true believers because, at the macro level, they believe in a gender ideology where women and men should be different and accept rules and requirements that enforce gender differentiation and even sex segregation in social life. In addition, at the interactional level, these Millennials report having been shaped by their parent’s traditional expectations and they similarly feel justified to impose gendered expectations on those in their own social networks. At the individual level, they have internalized masculinity or femininity, and embody it in how they present themselves to the world. They try hard to “do gender” traditionally.

Although attitudes toward interracial romantic relationships (IRRs) have generally improved over the years, many Americans still disapprove of their family members being in IRRs. Prior studies have examined correlates of individual-level attitudes about interracial romance, but less is known about whether family members’ attitudes are directly associated with young people’s decisions to date interracially. Using data collected from 790 romantically involved college students at two large public four-year universities, we find that young adults who believe their siblings, parents, and grandparents approve of IRRs have greater odds of dating interracially. Compared to Whites, Blacks and Hispanics are more likely to be interracially involved but their decision to do so is much less dependent on the approval of their parents and grandparents. We also find young adults are more likely to date interracially if they have five or more relatives with IRR experience themselves. The findings and their implications are discussed.

Absorptive capacity is a common barrier to knowledge transfer at the individual level. However, technology absorptive capacity can enhance an individual’s learning behaviour. This study investigates that technology readiness, the tools for knowledge sources, social influences, and social networks influence an individual’s absorptive capacity on an adaptation of the individual learning behaviour. A quantitative approach is used to assess the presence of a causal relationship from the constructs mentioned above. Data were collected from university students in Australia to examine the hypotheses. With 199 responses, a partial least squares structural equation modelling (PLS-SEM) approach was used for the analysis. The results generated mixed findings. Individual’s technological belief in optimism and innovation and social influences had a significantly weaker effect on individual absorptive capacity, which in turn had a significantly weaker impact on their learning behaviour.

Using Data

Conventional explanations of police misconduct generally adopt a microlevel focus on deviant officers or a macrolevel focus on the top-down organization of police departments. Between these levels are social networks of misconduct. This study recreates these networks using data on 16,503 complaints and 15,811 police officers over a six-year period in Chicago. We examine individual-level factors associated with receiving a complaint, the basic properties of these misconduct networks, and factors related to officer co-naming in complaints. We find that the incidence of police misconduct is associated with attributes including race, age, and tenure and that almost half of police officers are connected in misconduct ties in broader networks of misconduct. We also find that certain dyadic factors, especially seniority and race, strongly predict network ties and the incidence of group misconduct. Our results provide actionable information regarding possible ways to leverage the co-complaint network structure to reduce misconduct.
