Exploring variation in active network size: Constraints and ego characteristics

Studies of active personal networks have primarily focused on providing reliable estimates of the size of the network. In this study, we examine how compositional properties of the network and ego characteristics are related to variation in network size. There was a negative relationship between mean emotional closeness and network size, for both related and unrelated networks. Further, there was a distinct upper bound on total network size. These results suggest that there are constraints both on the absolute number of individuals that ego can maintain in the network, and also on the emotional intensity of the relationships that ego can maintain with those individuals.     

Migration,Policy, and Anthropology

In reviewing the articles in this special issue on the migration/policy/anthropology nexus, my comments will be in three parts: first, presenting a rough framework by which we might look at public policy in a way that bridges the academic and the practical; second, considering the actual cases presented in this special issue; and third, considering more broadly what the anthropological contribution might be to this complex and often acrimonious issue of migration policy. Throughout, the attempt is to search for a way of looking at migration policy that balances the inevitable academic critiques of public policy with a recognition of what public policy can and inevitably must be as a tool of societal discussion, planning, and progress.     

A Preliminary Investigation of Risks for Adverse Outcomes of Relationship Seeking on Social Network Sites (SNS): A Descriptive Study of Women Over 50 Seeking Relationships on MySpace in Hillsborough County,Florida

In contrast to younger populations, little attention has been paid to the increase in seniors using Internet-based venues to find relationships and the potential risk for adverse outcomes this poses. This study examined data collected via an online survey from 45 ethnically diverse women aged 50+ “seeking relationships” on MySpace. The majority of women reported a relationship with someone they met online (85%). They also reported experiencing adverse events including financial exploitation (40%), threats (55%), and physical harm (38%) by someone they met online at levels greater than traditional relationship seeking in the general population. Directions for future research are explored.     

‘Crossing lines of difference’: how college students analyse diversity

Contemporary American college students confront increased diversity during their college years—in race, class, nationality, religion, ethnicity, language, sexual orientation, age, and disability. Yet, how do students conceptualize this diversity, evaluate the options it provides, and assess its limitations? Furthermore, how do those researching diversity develop approaches that are flexible and open enough to reflect emerging student ways of thinking about diversity? Based on work at a diverse US public university—especially a pilot project on free‐form student essays—this paper examines how students conceptually navigate an environment that both encourages and inhibits interaction across difference. These students indicate scepticism about the marketing of diversity and frustration at the limited interaction across difference on campus, yet also an appreciation of the opportunities that diversity provides.

Analysis of longitudinal data with drop-out: objectives, assumptions and a proposal

Summary. The problem of analysing longitudinal data that are complicated by possibly informative drop-out has received considerable attention in the statistical literature. Most researchers have concentrated on either methodology or application, but we begin this paper by arguing that more attention could be given to study objectives and to the relevant targets for inference. Next we summarize a variety of approaches that have been suggested for dealing with drop-out. A long-standing concern in this subject area is that all methods require untestable assumptions. We discuss circumstances in which we are willing to make such assumptions and we propose a new and computationally efficient modelling and analysis procedure for these situations. We assume a dynamic linear model for the expected increments of a constructed variable, under which subject-specific random effects follow a martingale process in the absence of drop-out. Informal diagnostic procedures to assess the tenability of the assumption are proposed. The paper is completed by simulations and a comparison of our method and several alternatives in the analysis of data from a trial into the treatment of schizophrenia, in which approximately 50% of recruited subjects dropped out before the final scheduled measurement time.     

Respect: A philosophical perspective

This article explicates the concept of respect as philosophers discuss and utilize it. After identifying the main questions about respect which philosophers have raised and addressed, including questions about the nature, importance, objects, grounds, psychological and behavioral elements, and implications of respect, I sketch an account of the most general elements of the attitude of respect and identify different kinds of respect and their connections to and differences from similar attitudes such as esteem and honor. I then discuss the most influential account of respect for persons, that of Immanuel Kant. The final section explores the importance of respect in moral, social and political life and in moral, social, and political theory, and highlights some implications for issues in applied ethics and social and political theory.     

Women with fear of childbirth might benefit from having a known midwife during labour

Aim

Having a known midwife at birth is valued by women across the world, however it is unusual for women with fear of childbirth to have access to this model of care. The aim of this study was to describe the prevalence and factors related to having access to a known midwife for women referred to counseling due to childbirth fear. We also wanted to explore if women’s levels of childbirth fear changed over time.
