“Pretty Pressure” From Peers,Parents, and the Media: A Longitudinal Study of Appearance‐Based Rejection Sensitivity

Drawing from the tripartite sociocultural model of body image, the researchers examined whether direct messages and modeling from peers, parents, and media were concurrently and prospectively associated with appearance‐based rejection sensitivity (appearance‐RS) in young adolescents (M_age = 12.0 years). Appearance‐RS was higher among those who concurrently reported more appearance‐related teasing and pressure by peers, more parent teasing, and greater acceptance of media appearance ideals. In prospective analyses, greater increases in appearance‐RS over 1 year were found for adolescents who perceived higher levels of parental appearance‐related teasing and negative attitudes about their own appearance. Moderation analyses indicated the positive prospective association between parental negative appearance attitudes and appearance‐RS was found in younger but not older participants. Gender did not moderate associations.     

Stochastic Choice and Revealed Perturbed Utility

Perturbed utility functions—the sum of expected utility and a nonlinear perturbation function—provide a simple and tractable way to model various sorts of stochastic choice. We provide two easily understood conditions each of which characterizes this representation: One condition generalizes the acyclicity condition used in revealed preference theory, and the other generalizes Luce's IIA condition. We relate the discrimination or selectivity of choice rules to properties of their associated perturbations, both across different agents and across decision problems. We also show that these representations correspond to a form of ambiguity‐averse preferences for an agent who is uncertain about her true utility.     

Heavy drinking on college campuses: no reason to change minimum legal drinking age of 21

The recent Amethyst Initiative argues that a minimum legal drinking age (MLDA) of 21 has created a culture of heavy alcohol use on college campuses by making drinking clandestine and extreme. This group and others argue that lowering the MLDA will reduce the problem of "binge drinking" on college campuses. However, such a policy change would remove one of the most researched and supported policies in the nation's alcohol control arsenal. There is little evidence that other interventions or policies are capable of working on the same broad level as MLDA 21, and there could also be a deleterious ripple effect in related legislation because MLDA 21 works in conjunction with other drinking laws. In addition, historic and international experiences with a lowered MLDA indicate there are serious social and public health consequences. Instead of removing efficacious interventions, we must remain committed to implementing and enforcing evidence-based practices and legislation.     

Time dynamics of elder victimization: Evidence from the NCVS, 1992 to 2005

Persons who are relatively younger have a comparably higher incidence of crime victimization than those who are older. Comparative studies of crime rates among those 65 and older with those for younger persons across time are virtually nonexistent. This study provides these analyses. Data from the National Crime Victimization Survey are used to study the relative victimization rate among US elders. Macroeconomic indicators and environmental interventions were included to examine whether structural forces influence elder crime victimization rates. Such influences are fractionally cointegrated with the long-term elder property and personal crime rates, with each having a distinct data-generating process. The results of these analyses suggest that personal, but not property, crime rates have declined since the passage of the Crime Bill of 1994. As well, the summer months are associated with elevated rates of property crime committed against elders but not personal crime.     

A Survey of Sequential Monte Carlo Methods for Economics and Finance

This article serves as an introduction and survey for economists to the field of sequential Monte Carlo methods which are also known as particle filters. Sequential Monte Carlo methods are simulation-based algorithms used to compute the high-dimensional and/or complex integrals that arise regularly in applied work. These methods are becoming increasingly popular in economics and finance; from dynamic stochastic general equilibrium models in macro-economics to option pricing. The objective of this article is to explain the basics of the methodology, provide references to the literature, and cover some of the theoretical results that justify the methods in practice.     

Peer Groups, Social Identity, and Children's Bullying Behavior

Drawing on social identity theory, this study explored the impact of the peer group on childhood bullying. Participants were 351 students, aged 8 to 13 years. Involvement in bullying, friendship group membership, norms of particular groups, and intra-group positions (prototypical vs. peripheral) were determined using peer reports. Results revealed within-group similarities in bullying behaviors. In addition, bullying was found to be greater when it was endorsed by group norms and when children were prototypical vs. peripheral members of bullying groups. The implications of the findings for the conceptualization of childhood bullying are discussed.     

Combating the social isolation of chronic mental illness

1. The diminished mental and emotional resources suffered by those with chronic mental illness (CMI) often lead to impoverished relationships that fail to produce satisfying connections with others. As a result, persons with CMI are frequently chronically lonely. 2. Moreno's sociometric principles and psychodramatic techniques for group therapy provide ways to increase interconnectedness with others by interrupting the self-reinforcing aspects of social isolation. 3. Role reversal, self-presentation, psychodramatic encounter, and sociometric exercises facilitate expanded emotional repertoire, let members know each other, provide relief from emotional distress, and produce information about the group needed to generate interaction.     

Promoting Transparency of Long-Term Environmental Decisions: The Hanford Decision Mapping System Pilot Project

Nuclear waste cleanup is a challenging and complex problem that requires both scientific analysis and dialogue among a variety of stakeholders. This article describes an effort to develop an online information system that supports this analytic-deliberative dialogue by integrating cleanup information for the Hanford Site, and making it more "transparent." A framework for understanding and evaluating transparency guided system development. Working directly with stakeholders, we identified information needs and developed new ways to organize and present the information so that it would be more transparent to interested parties, with the ultimate aim of fostering greater participation in decision dialogues and processes. The complexity of the information needed for dialogue suggested that several types of communication devices ("information structures") were warranted. Five information structures were developed for the pilot Decision Mapping System (http://nalu.geog.washington.edu/dms). Decision maps hyperlinked decision information to maps of Hanford. Background Information provided context in a narrative format. Decision Paths organized decision process information on a timeline and provided direct hyperlinks to online documentation. The Geographic Library hyperlinked decision documents to maps. Finally, a Discussion Forum allowed users to make comments and view remarks from others. Early lessons from this work suggest that transparency is integral to long-term management, a participatory design process contributed greatly to its perceived success, and better data integration to support decision making is needed. This work has broad implications for risk communicators and risk managers because it speaks to the design of information systems to support "analytic-deliberative" decision processes (i.e., those that rely upon both risk science and public dialogue).
