Introducing systems change in the schools: the case of school luncheons and vending machines

A major public health crisis facing America’s society is the increase in child and youth obesity, which has seen a fourfold increase in the last four decades. Major concerns include what children eat for school lunch and what other foods are available in schools. This paper illustrates efforts towards systems change in the luncheon program and food vending machines in the Chicago Public Schools. We discuss the different factors that lead to such changes using the framework of the social ecological model and the soft systems methodology, and we analyze how the resulting innovation was implemented and evaluated. First, we present a theoretical perspective to explain factors that influence children’s eating patterns from a systems approach. Second, we discuss the antecedent factors that lead to systems change. Finally, we examine challenges to systems change, such as resistance to change, different stakeholder priorities, lack of resources, institutional bureaucracy, and unrealistic funder expectations.     

Relationship of pain tolerance with human aggression

In research with animals as well as samples of chronic pain patients and elderly persons, pain has been positively correlated with measures of irritability, hostility, and aggression. The present investigation examined the relationship of pain tolerance with aggression. 72 men participated in the Response Choice Aggression Paradigm, described previously by Zeichner and colleagues, in which aggressive response to provocation was possible but not required of participants. Subjective pain tolerance, defined as maximal electrical shock willingly tolerated by participants, was assessed. Significant but small Pearson product-moment correlations between pain tolerance and aggression ranged between .21 and .32, with the largest accounting for 9% of variance.     

Psychosocial stress evoked by a virtual audience: relation to neuroendocrine activity.

A modified version of the Trier Social Stress Test (TSST) was employed to determine whether exposure to a virtual audience using virtual reality (VR) technology would prompt an increase of neuroendocrine activity comparable to that prompted by a real audience. Following an anticipatory period, participants completed a speech or a speech-plus-math challenge in front of either a virtual audience, a panel of judges they were led to believe was behind a one-way mirror, or an audience comprised of confederates. An additional group that had prepared a speech was simply directed to observe the virtual audience but did not deliver the speech. Finally, a control group completed questionnaires for the duration of the experiment. Cortisol samples were obtained upon arrival to the laboratory, just before the challenge, and 15 and 30 minutes after the task. Participants also completed a measure assessing stressor appraisals of the task before and after the challenge. Anticipation of the task was associated with a modest increase of cortisol levels, and a further rise of cortisol was evident in response to the challenge. The neuroendocrine changes evoked by the virtual audience were comparable to those elicited by the imagined audience (behind the one-way mirror) but less than changes evoked by the panel of confederates. Stressor appraisals were higher post-challenge compared to those reported prior to the task; however, appraisals were similar across each group. These data suggest that VR technology may be amenable to evaluating the impact of psychosocial stressors such as the TSST.     

GROUP GENDER COMPOSITION EFFECTS ON JUDGMENTS OF SEXUAL HARASSMENT

This article examines the effects of participant gender, researcher gender, and group gender composition (ratio of women to men) on individual judgments about an ambiguous, hypothetical, sexual harassment grievance. The participants (116 men and 113 women) served on five-person mock hearing boards. A main effect for participant gender was found ( p <.01), with significantly more women (58.4%) making affirmative sexual harassment judgments than men (35.3%). A significant three-way interaction ( p <.01) revealed that, when led by male researchers, men in groups where they were the numerical minority (3 women/2 men) made significantly lower ratings, indicating less belief that sexual harassment had occurred ( M = 2.83), than those men in groups where they were in the majority (2 women/3 men, M = 4.87; 4 men/1 woman, M = 4.88). Ingroup and outgroup behavior observed by Rogers, Hennigan, Bowman, and Miller (1984) is proposed as a possible explanation for these results.     

This century,this country: One survivor's story of posttraumatic stress syndrome

Abstract

Posttraumatic stress syndrome, also called posttraumatic stress disorder (PTSD), affects people who have experienced extremely traumatic events. Individuals who live with posttraumatic stress syndrome must continually overcome many obstacles to live their daily lives. The following is one woman's story of abuse, its after effects, and survival. By telling her story, I hope to make her suffering that much more meaningful. In addition, I wish to call attention to what goes on behind closed doors and explain what we can do about it.     

Race,Belonging, and Participation in Religious Congregations

Significant effort has gone into understanding and promoting racial diversity in congregations. Still, uniting worshippers of different races remains a challenging endeavor. Even congregations that successfully attract worshippers of different races often have difficulty sustaining their multiracial composition. This study contributes to the discussion of race and religion by examining racial group differences in belonging and participation in congregations. Drawing on organizational ecology theory, we develop four hypotheses to test whether and how racial group size corresponds to congregational commitment. Results of multilevel modeling using 2001 U.S. Congregational Life Survey data reveal that those who are a part of a congregation's largest racial group possess a stronger sense of belonging and participate at a deeper level than congregants of other races. Moreover, differences in belonging and participation by racial group persist regardless of group size.     

Religious propositional attitudes and underdetermination of public representation: Commentary on Ara Norenzayan's Big Gods

The commentary addresses a specific aspect of Norenzayan's work: the use of the notion of credible display as developed by J. Henrich (“The Evolution of Costly Displays, Cooperation and Religion: Credibility Enhancing Displays and their Implications for Cultural Evolution,” Evolution and Human Behavior 30 [4] 2009: 244–260) to make sense of typical (extravagant) religious behaviors. Norenzayan ascribes an essential role to those displays in the diffusion of religious beliefs. The authors maintain that to use the concept of CRED is not appropriate given the typical natures of religious beliefs and behaviors. Contrary to Norenzayan's essential claim in Big Gods, they defend the hypothesis that audiences have no indubitable way of inferring from religious actions the religious beliefs of performing agents. It is essentially explained by the fact that there does not exist any necessary link between proclaimed religious beliefs and observable religious behaviors. Religious behaviors are public representations, generally more or less rigidly stipulated, hence they typically have more to do with social coordination than with genuine expression of performers' religious propositional attitudes, that is, they do not require genuine religious beliefs. Furthermore, as there is no guarantee or necessity that the religious behavior be systematically associated to true beliefs, such behaviors are eminently recruitable for individual aims and ends (social gains, status enhancement), which might partly explain why they get maintained in various cultural traditions.     

Aggressive and Prosocial Behavior: Community Violence, Cognitive, and Behavioral Predictors Among Urban African American Youth

We use longitudinal multilevel modeling to test how exposure to community violence and cognitive and behavioral factors contribute to the development of aggressive and prosocial behaviors. Specifically, we examine predictors of self-, peer-, and teacher-reported aggressive and prosocial behavior among 266 urban, African American early adolescents. We examine lagged, within-person, between-person, and protective effects across 2 years. In general, results suggest that higher levels of violence exposure and aggressive beliefs are associated with more aggressive and less prosocial peer-reported behavior, whereas greater self-efficacy to resolve conflict peacefully is associated with less aggression across reporters and more teacher-reported prosocial behavior. Greater knowledge and violence prevention skills are associated with fewer aggressive and more prosocial teacher-reported behaviors. Results also suggest that greater self-efficacy and lower impulsivity have protective effects for youth reporting higher levels of exposure to community violence, in terms of teacher-reported aggressive behavior and peer-reported prosocial behavior. Differences among reporters and models are discussed, as well as implications for intervention.     

Manipulating self-efficacy in the exercise environment in women: influences on affective responses.

Self-efficacy was experimentally manipulated in an exercise context, and its effect on affective responses was examined. College women (N = 46) were randomly assigned to a high- or low-efficacy condition, and efficacy expectations were manipulated by means of bogus feedback and graphs depicting contrived normative data. The manipulation successfully influenced affective responses, with participants in the high-efficacy group reporting more positive and less negative affect than did the low-efficacy group. Efficacy was significantly related to feeling-state responses during and after activity but only in the high-efficacy condition. The results suggest that self-efficacy can be manipulated and that these changes are related to the affective experience associated with exercise. Such findings may have important implications for the roles played by self-efficacy and affect in exercise adherence.
