Plato's Child and the Limit-Points of Educational Theories

This paper analyzes how the figure of the childhas been used to authorize a series ofboundaries that have constituted thelimit-points of educational theories orphilosophies. Limit-points are the conceptualboundaries that educational theories produce,move within, respond to, and make use ofbecause the perception is that they cannot beargued away or around at the time. A method ofcomparative historico-philosophy is used tocontrast limit-points in Platonic figurationsof the child and education with childcenteredand eugenic theories of the late nineteenth andtwentieth century West. The figuration of thechild in both periods is imbricated in formingboundaries around a power-motion-reason nexusand in delineating what necessity and justicemean. The meaning-space that the child canoccupy in relation to such concepts has shiftedwith them and has been important to depictingUtopian and cosmological imaginings atdifferent historical moments and forauthorizing in turn what counts as anappropriate and/or realistic educationalphilosophy.     

The role of glutamate in anxiety and related disorders

Anxiety, stress, and trauma-related disorders are a major public health concern in the United States. Drugs that target the gamma-aminobutyric acid or serotonergic system, such as benzodiazepines and selective serotonin reuptake inhibitors, respectively, are the most widely prescribed treatments for these disorders. However, the role of glutamate in anxiety disorders is becoming more recognized with the belief that drugs that modulate glutamatergic function through either ionotropic or metabotropic glutamate receptors have the potential to improve the current treatment of these severe and disabling illnesses. Animal models of fear and anxiety have provided a method to study the role of glutamate in anxiety. This research has demonstrated that drugs that alter glutamate transmission have potential anxiolytic action for many different paradigms including fear-potentiated startle, punished responding, and the elevated plus maze. Human clinical drug trials have demonstrated the efficacy of glutamatergic drugs for the treatment of obsessive-compulsive disorder, posttraumatic stress disorder, generalized anxiety disorder, and social phobia. Recent data from magnetic resonance imaging studies provide an additional link between the glutamate system and anxiety. Collectively, the data suggest that future studies on the mechanism of and clinical efficacy of glutamatergic agents in anxiety disorders are appropriately warranted.     

The Role of Sexual Trauma in the Treatment of Chemically Dependent Women: Addressing the Relapse Issue

A review of the literature indicates a high incidence of sexual trauma among women who seek treatment for substance abuse. Additionally, clients who have experienced sexual trauma appear to be more susceptible to relapse, the return to substance abuse. This article explores issues surrounding sexual trauma and chemical dependency. It aims to provide direction for relapse prevention with a relapse-prone population. Application of traditional milieu substance abuse treatment for sexual trauma survivors is explored. Recommendations for working with sexual trauma survivors who are also substance abusers are presented, as are suggestions for research.     

Expert testimony in pornography trials: A role for the social scientist

This article attempts to clarify the concepts of law, pornography, and the special role of the expert witness in pornography. Different conceptual frameworks taken by experts in this field are addressed, as are the shortcomings of various approaches. Finally, the critical role of ethics in giving expert witness testimony in pornography is discussed.     

The influence of stereotypes on decisions to shoot

Using a videogame to simulate encounters with potentially hostile targets, three studies tested a model in which racial bias in shoot/don't-shoot decisions reflects accessibility of the stereotype linking Blacks to danger. Study 1 experimentally manipulated the race-danger association by asking participants to read newspaper stories about Black (vs. White) criminals. As predicted, exposure to stories concerning Black criminals increased bias in the decision to shoot. Studies 2 and 3 manipulated the number of White and Black targets with and without guns in the context of the videogame itself. As predicted, frequent presentation of stereotypic (vs. counterstereotypic) targets exacerbated bias (Study 2) and—consistent with our process account—rendered stereotypes more accessible (Study 3).

Credit use: psychological perspectives on a multifaceted phenomenon

Consumer borrowing is a highly topical and multifaceted phenomenon as well as a popular subject for study. We focus on consumer credit use and review the existing literature. To categorize what is known we identify four main psychological perspectives on the phenomenon: credit use as (1) a reflection of the situation, (2) a reflection of the person, (3) a cognitive process, and (4) a social process. On top of these perspectives we view credit use as a process that entails three distinct phases: (1) processes before credit acquisition, (2) processes at credit acquisition, and (3) processes after credit acquisition. We review the international literature along a two-tier structure that aligns the psychological perspectives with a process view of credit. This structure allows us to identify systematic concentrations as well as gaps in the existing research. We consolidate what is known within each perspective and identify what seems to be most urgently missing. Some of the most important gaps relate to research studying credit acquisition from the perspective of credit use as a reflection of the person or as a social process. In particular, research on credit use as a reflection of the person appears to focus exclusively on the first stage of the credit process. We conclude with a discussion that reaches across perspectives and identifies overarching gaps, trends, and open questions. We highlight a series of implicit linkages between perspectives and the geographical regions in which studies related to the perspectives were conducted. Beyond diagnosing a geographical imbalance of research, we argue for future research that systematically addresses interrelations between perspectives. We conclude with a set of global implications and research recommendations.     

The restorative effects of smoking upon self-control resources: a negative reinforcement pathway

Based on a model in which self-control (SC) is considered to be a limited resource, research suggests that diminished SC resources may increase the likelihood of tobacco smoking. Yet, the inverse--how smoking may influence SC resources--has not been tested. The authors of this study utilized a randomized, 2 × 2 crossed-factorial (SC Depletion Manipulation × Smoking Manipulation), between-subjects design to test the hypothesis that smoking restores depleted SC resources. To manipulate SC depletion, experimenters instructed half of 132 nicotine dependent smokers to suppress their emotional reaction to a brief video depicting environmental damage (i.e., depletion), whereas the other half were instructed to "act natural" (i.e., no depletion) during viewing. Half of the participants in each condition then smoked a cigarette, whereas the other half sat patiently without smoking (i.e., smoke vs. no smoke). All participants then completed behavioral measures of SC. As hypothesized, an interaction occurred between the depletion and smoking manipulations for duration of time spent on a frustrating mirror-tracing task. That is, depletion reduced persistence on the task, unless depletion was followed by smoking. This effect was mediated by positive affect (PA). Thus, smoking appeared to restore depleted SC resources via modulation of PA, but independent of negative affect or smoking urges. These findings suggest that restoration of SC resources may represent another means by which smoking is negatively reinforced. The application of the self-control strength model to the study of nicotine dependence may inform the development of novel treatment modalities.
