We revisit long-term politically active citizens at the Three Mile Island nuclear plant in the wake of ongoing environmental and nuclear crises in Japan to better understand how long-term citizen participation focused on environmental disasters might be fostered and sustained. In our qualitative study of 31 long-term antinuclear activists, we examine the confluence of psychological and sociopolitical dimensions of active citizenship for over 3 decades. Psychological dimensions include moral obligations and civic-mindedness, emotions, such as anger, stress, and deepened convictions, and the importance of social solidarity and silent supporters. Sociopolitical dimensions include the lack of social power, the importance of formal groups, and strong leadership. Additionally, we compare first-time active citizens with those with prior political experience and argue that at least 2 types of active citizens may exist: those who are intrinsically inspired and those who are motivated by a direct threat. Implications for promoting increased active citizenship around environmental and technological crises are discussed.

To assess the scope of analyses of social power in community psychology (CP), we examined articles published in the American Journal of Community Psychology and Journal of Community Psychology from their inception in 1973 through 2010 for reference to the concept “power.” We discovered two historical points, 30 years apart, where power gained attention: early in the development of the field as it moved away from individualized notions of mental health and more recently as attention has shifted toward psycho-political considerations. Despite the belief that power has been neglected in favor of its linguistic relative, “empowerment,” we found that scholarship spanned ecological levels, including individual (e.g., empowerment, referent power, and citizen participation), group (e.g., communities and organizations/institutions), and structural (e.g., macro concepts and marginalized statuses) analyses. By synthesizing scholarship on power in CP, we can provide a foundation from which to expand the field and effect social change.

Intertemporal decision-making refers to choices among options that vary in both magnitude and delay to arrival (e.g., choices between a small, immediate reward vs a large, delayed reward). An individual’s preference for immediate over delayed rewards depends in part on the degree to which delays reduce (discount) the rewards’ subjective value, and is considered to be one dimension of impulsivity (“impulsive choice”). A large body of literature has demonstrated elevated levels of impulsive choice in chronic cocaine users. This chapter begins by reviewing this literature in terms of the direction of causality in the relationship between cocaine use and impulsive choice (whether high levels of impulsive choice are a predisposing factor for or a consequence of cocaine use). The chapter goes on to discuss research in animal models that has begun to address these causal relationships, as well as neural mechanisms that may underlie these relationships.

Exposure to tobacco smoke during pregnancy is associated with a range of adverse outcomes in offspring, including cognitive deficits and increased incidence of attention deficit-hyperactivity disorder, but there is a considerable controversy with regard to the causal role of tobacco smoke in these outcomes. To determine whether developmental exposure to the primary psychoactive ingredient in tobacco smoke, nicotine, may cause long-lasting behavioral alterations analogous to those in attention deficit-hyperactivity disorder, male Sprague-Dawley rats underwent a chronic neonatal nicotine administration regimen, which models third-trimester human exposure. Male rat pups were administered nicotine (6 mg/kg/day) by oral gastric intubation on postnatal days 1-7. In adulthood, rats were tested in two decision-making tasks (risky decision-making and delay discounting) as well as in free-operant responding for food reward and the elevated plus maze. Chronic neonatal nicotine attenuated weight gain during nicotine exposure, but there were no effects on performance in the decision-making task, and only a modest decrease in arm entries in the elevated plus maze in one subgroup of rats. These data are consistent with previous findings that developmental nicotine exposure has no effect on delay discounting, and they extend these findings to risky decision-making as well. They further suggest that at least some neurocognitive alterations associated with prenatal tobacco smoke exposure in humans may be due to genetic or other environmental factors, including non-nicotine components of tobacco smoke.

Nuclear energy has received substantial recent attention, marketed as a ‘green’ solution to global climate change (GCC) with calls for new reactors. However, considerable debate exists about whether it represents a viable solution to GCC. Given the complexity and urgency of the issue, a full and balanced debate is desirable. Since media play an important role in shaping public perception, we examined print media coverage of proposed reactors in Georgia—one site in the southeastern United States, which has been the focus of such proposals. We analysed the content of editorials and news articles from two local newspapers—the Augusta Chronicle and Atlanta Journal-Constitution. The former exclusively published pro-nuclear opinion pieces whereas the latter published a mix of pro- and anti-nuclear opinions. The majority of news articles in both newspapers generally presented balanced arguments. Pro- and anti-nuclear arguments most often reflected economic and environmental benefits and risks, whereas informational text primarily detailed regulatory processes and financing. Findings suggested that informational text was not necessarily ‘neutral’, sometimes masking covert pro- and anti-nuclear content. Implications for how findings might shape public opinion and strategies for shaping media and extending public deliberation are discussed. Copyright © 2010 John Wiley & Sons, Ltd.

Cocaine use is associated with high levels of impulsive choice (preference for immediate over delayed rewards), but it is not clear whether cocaine use causes elevated impulsive choice, or whether elevated impulsive choice is solely a predisposing factor for cocaine use. This study examined the effects of prior cocaine self-administration on rats performing a delay discounting task commonly used to measure impulsive choice. Male Long-Evans rats were implanted with intravenous catheters, and following recovery, were trained to self-administer 30 mg/kg/day cocaine HCl (approx. 0.5 mg/kg/infusion) for 14 consecutive days (a control group received yoked intravenous saline infusions). Following three weeks of withdrawal, all rats were food-restricted and began training on the delay discounting task in standard operant chambers. On each trial, rats were given a choice between two levers. A press on one lever delivered a small food reward immediately, and a press on the other delivered a large food reward after a variable delay period. Rats that self-administered cocaine displayed greater impulsive choice (enhanced preference for the small immediate over the large delayed reward, as reflected by shorter indifference points) compared to controls, but were no different from controls on a "probabilistic discounting" task in which they chose between small certain and large uncertain rewards. These data suggest that self-administered cocaine can cause lasting elevations in impulsive choice, and that the high levels of impulsive choice observed in human cocaine users may be due in part to long-term effects of cocaine on brain function.

Drug addicted individuals demonstrate high levels of impulsive choice, characterized by preference for small immediate over larger but delayed rewards. Although the causal relationship between chronic drug use and elevated impulsive choice in humans has been unclear, a small but growing body of literature over the past decade has shown that chronic drug administration in animal models can cause increases in impulsive choice, suggesting that a similar causal relationship may exist in human drug users. This article reviews this literature, with a particular focus on the effects of chronic cocaine administration, which have been most thoroughly characterized. The potential mechanisms of these effects are described in terms of drug-induced neural alterations in ventral striatal and prefrontal cortical brain systems. Some implications of this research for pharmacological treatment of drug-induced increases in impulsive choice are discussed, along with suggestions for future research in this area.

Resume La psychologie communautaire est une branche appliquee de la psychologie qui a vu le jour grâce a la conjoncture d’evenements sociaux importants et de reformes politiques aux Etats-Unis comme au Canada. Cet article vise a dresser un portrait de l’historique respectif de la psychologie communautaire pour ces deux pays et de situer quelques elements cles a la base de sa creation. Par le recours a la presentation de projets d’actions et de recherches communautaires recenses dans la litterature, cet article tend a rendre compte des domaines d’application et champs d’action divers de cette discipline, qui est aujourd’hui tres active en Amerique du Nord.

This article examines women who have been antinuclear activists at the Three Mile Island nuclear power plant for two decades. Qualitative interviews focus on their perceived transformations over time that are based on gender and everyday experiences. They perceive gender as both a barrier and a facilitator to activism, even after 20 years. Women describe their technological education as one strategy to overcome the barrier of gender. On the other hand, they consider the gendered role of motherhood as a primary catalyst for action. In addition, they discuss individual everyday experiences focused on the health concerns for family members that influenced their political activity. Over time, women linked personal transformations with increased political understanding and involvement.

Articles about women's issues published in the American Journal of Community Psychology and Journal of Community Psychology, from their inception in 1973 through 2000 were examined for feminist content. Feminism was defined as including consciousness of gender issues, gender-stratified power imbalances, and contextual analyses of gender. We identified 89 articles with feminist content. All 89 feminist articles were examined to identify themes of gender consciousness and intersecting identities. Within the theme of gender consciousness, we identified articles that addressed power asymmetries, the link between individuals and environments, contextual analyses, and a focus on competencies. Within the theme of intersecting identities, we identified articles that addressed race, class, sexual orientation, and disabilities. We discuss the trend toward more feminist research and explore ways create a feminist subdiscipline within the field of community psychology. Finally, we discuss recommendations for future feminist scholarship in the field. © 2003 Wiley Periodicals, Inc. J Comm Psychol 31: 189–209, 2003.

Contains fulltext : 142484.pdf (Publisher’s version ) (Closed access) Impulsivity critically relates to many psychiatric disorders. Given the multifaceted construct that impulsivity represents, defining core aspects of impulsivity is vital for the assessment and understanding of clinical conditions. Choice impulsivity (CI), involving the preferential selection of smaller sooner rewards over larger later rewards, represents one important type of impulsivity. The International Society for Research on Impulsivity (InSRI) convened to discuss the definition and assessment of CI and provide recommendations regarding measurement across species. Commonly used preclinical and clinical CI behavioral tasks are described, and considerations for each task are provided to guide CI task selection. Differences in assessment of CI (self-report, behavioral) and calculating CI indices (e.g., area-under-the-curve, indifference point, and steepness of discounting curve) are discussed along with properties of specific behavioral tasks used in preclinical and clinical settings. The InSRI group recommends inclusion of measures of CI in human studies examining impulsivity. Animal studies examining impulsivity should also include assessments of CI and these measures should be harmonized in accordance with human studies of the disorders being modeled in the preclinical investigations. The choice of specific CI measures to be included should be based on the goals of the study and existing preclinical and clinical literature using established CI measures. 17 p.

Cocaine use is associated with high levels of impulsive choice (greater discounting of delayed rewards) in humans, but the cause/effect relationships between cocaine use and impulsive choice are not fully understood. In previous work, we found that both experimenter- and self-administration of fixed quantities of cocaine caused lasting increases in impulsive choice in rats. The present study extended these findings by taking into account baseline impulsive choice prior to self-administration, and by allowing rats free access to cocaine. Male Long-Evans rats were trained in a delay discounting task in which they made discrete-trial choices between small immediate and large delayed food rewards. Half of the rats were then implanted with intravenous catheters and, following recovery, allowed to self-administer cocaine HCl (1.0 mg/kg/infusion) in 6 hour sessions over 14 days. Control rats orally self-administered a sucrose solution under similar conditions. Upon completion of self-administration training, rats remained abstinent for 3 weeks before retesting in the delay discounting task. Cocaine and control groups did not differ prior to self-administration, but afterward, the cocaine group showed greater impulsive choice (fewer choices of large, delayed rewards) than controls. Additional analyses revealed that the effects of cocaine on impulsive choice were intake-dependent; rats classified as “low intake” did not differ from controls, whereas rats classified as “high intake” were significantly more impulsive than both controls and their pre-cocaine baseline. These findings are consistent with the idea that cocaine-induced, pharmacologically based neural adaptations promote the development of impulsive decision making.

Behavioral tendencies that might be captured through self-report measures may provide insight into personality features that are associated with substance addictions. Recently, impulsivity and related constructs, such as sensation-seeking, have been examined to help better understand their relationships with addictions. Here, we review recent findings that show links over developmental epochs between addictive behaviors and impulsivity, sensation-seeking, and other constructs that are theoretically linked. These findings have significant implications for generating improved treatments and interventions aimed at preventing the development of addictive disorders.

Cocaine-dependent individuals demonstrate neural and behavioral differences compared to healthy comparison subjects when performing the Stroop color-word interference test. Stroop measures also relate to treatment outcome for cocaine dependence. Intrinsic connectivity analyses assess the extent to which task-related regional brain activations are related to each other in the absence of defining a priori regions of interest.This study examined 1) the extent to which cocaine-dependent and non-addicted individuals differed on measures of intrinsic connectivity during fMRI Stroop performance; and 2) the relationships between fMRI Stroop intrinsic connectivity and treatment outcome in cocaine dependence.Sixteen treatment-seeking cocaine-dependent patients and matched non-addicted comparison subjects completed an fMRI Stroop task. Between-group differences in intrinsic connectivity were assessed and related to self-reported and urine-toxicology-based cocaine-abstinence measures.Cocaine-dependent patients vs. comparison subjects showed less intrinsic connectivity in cortical and subcortical regions. When adjusting for individual degree of intrinsic connectivity, cocaine-dependent vs. comparison subjects showed relatively greater intrinsic connectivity in the ventral striatum, putamen, inferior frontal gyrus, anterior insula, thalamus and substantia nigra. Non-mean-adjusted intrinsic-connectivity measures in the midbrain, thalamus, ventral striatum, substantia nigra, insula and hippocampus negatively correlated with measures of cocaine abstinence.The diminished intrinsic connectivity in cocaine-dependent vs. comparison subjects suggests poorer communication across brain regions during cognitive-control processes. In mean-adjusted analyses, the cocaine-dependent group displayed relatively greater Stroop-related connectivity in regions implicated in motivational processes in addictions. The relationships between treatment outcomes and connectivity in the midbrain and basal ganglia suggest that connectivity represents a potential treatment target.

Poor decision making and elevated risk taking, particularly during adolescence, have been strongly linked to drug use; however the causal relationships among these factors are not well understood. To address these relationships, a rat model (the Risky Decision-making Task; RDT) was used to determine whether individual differences in risk taking during adolescence predict later propensity for cocaine self-administration and/or whether cocaine self-administration causes alterations in risk taking. In addition, the RDT was used to determine how risk taking is modulated by dopamine signaling, particularly in the striatum. Results from these experiments indicated that greater risk taking during adolescence predicted greater intake of cocaine during acquisition of self-administration in adulthood, and that adult cocaine self-administration in turn caused elevated risk taking that was present following 6 weeks of abstinence. Greater adolescent risk taking was associated with lower striatal D2 receptor mRNA expression, and pharmacological activation of D2/3 receptors in the ventral, but not dorsal, striatum induced a decrease in risk taking. These findings indicate that the relationship between elevated risk taking and cocaine self-administration is bi-directional, and that low striatal D2 receptor expression may represent a predisposing factor for both maladaptive decision making and cocaine use. Furthermore, these findings suggest that striatal D2 receptors represent a therapeutic target for attenuating maladaptive decision making when choices include risk of adverse consequences.

This study, was designed to determine the effectiveness of counterattitudinal advocacy in overcoming beginning students' erroneous beliefs about psychological phenomena. Introductory psychology students (N = 71) either wrote an essay (counterattitudinal advocacy) or read an essay supporting a scientifically acceptable position contrary to one of their beliefs. Writing a counterattitudinal essay was more effective in changing students' beliefs than either reading such an essay or learning about the topic through Standard pedagogical techniques. The method of delivering instructional materials (lecture vs. text vs. both lecture and text) made no significant difference in the elimination of erroneous beliefs.

Lower gastrointestinal hemorrhage is a common clinical problem for which multiple diagnostic tests and therapeutic interventions have been developed but no optimal approach has been established. We reviewed 107 consecutive patients admitted to the Massachusetts General Hospital for management of acute lower gastrointestinal hemorrhage to determine the effectiveness of diagnostic and management technologies, with particular attention to urgent colonoscopy. Colonoscopy yielded a diagnosis in 90% of patients, provided the opportunity for successful therapy in 9 of 13 patients (69%), and shortened hospital stay. Angiography performed after a scan positive for bleeding was often diagnostic, and angiography provided the means for successful therapy in 5 of 10 patients (50%). Barium enema and sigmoidoscopy had lower clinical yields. Although roles exist for other technologies, colonoscopy is the most convenient and effective first test in the evaluation of patients with significant lower gastrointestinal hemorrhage. Diagnostic yield, therapeutic opportunity, and cost effectiveness are maximized in early studies.

Von Hippel-Lindau (VHL) disease is an autosomal dominant syndrome that, due to loss of tumor suppressor gene function, predisposes affected individuals to various benign and malignant tumors including renal cell cancer. In contrast, lymphomas are a varied group of clonal diseases arising from a lymphocyte progenitor and can affect any site of the lymphatic system. We present the case of a 56 year old female with Von Hippel-Lindau disease and clear cell renal carcinoma (CCRC), who developed a nasopharyngeal mass with cervical and submandibular lymphadenopathy subsequently proven to be a Non Hodgkin’s lymphoma (NHL). Though the association between VHL and renal cell cancer is significant, a mechanism linking these two diseases has previously been unknown. To the best of our knowledge, this is the first reported case of a patient presenting with coexistent VHL and NHL. In an effort to explain this rarity, we propose that a defective VHL allele may serve as a possible link between VHL and RCC, thus leading to an environment that would favour the development of a malignant clone, our patient’s NHL.

Many psychiatric disorders are characterized by abnormal risky decision-making and dysregulated dopamine receptor expression. The current study was designed to determine how different dopamine receptor subtypes modulate risk-taking in young adult rats, using a “Risky Decision-making Task” that involves choices between small “safe” rewards and large “risky” rewards accompanied by adverse consequences. Rats showed considerable, stable individual differences in risk preference in the task, which were not related to multiple measures of reward motivation, anxiety, or pain sensitivity. Systemic activation of D2-like receptors robustly attenuated risk-taking, whereas drugs acting on D1-like receptors had no effect. Systemic amphetamine also reduced risk-taking, an effect which was attenuated by D2-like (but not D1-like) receptor blockade. Dopamine receptor mRNA expression was evaluated in a separate cohort of drug-naive rats characterized in the task. D1 mRNA expression in both nucleus accumbens shell and insular cortex was positively associated with risk-taking, while D2 mRNA expression in orbitofrontal and medial prefrontal cortex predicted risk preference in opposing nonlinear patterns. Additionally, lower levels of D2 mRNA in dorsal striatum were associated with greater risk-taking. These data strongly implicate dopamine signaling in prefrontal cortical-striatal circuitry in modulating decision-making processes involving integration of reward information with risks of adverse consequences.

Impaired decision-making in aging can directly impact factors (financial security, health care) that are critical to maintaining quality of life and independence at advanced ages. Naturalistic rodent models mimic human aging in other cognitive domains, and afford the opportunity to parse the effects of age on discrete aspects of decision-making in a manner relatively uncontaminated by experiential factors. Young adult (5–7 months) and aged (23–25 months) male F344 rats were trained on a probability discounting task in which they made discrete-trial choices between a small certain reward (one food pellet) and a large but uncertain reward (two food pellets with varying probabilities of delivery ranging from 100 to 0%). Young rats chose the large reward when it was associated with a high probability of delivery and shifted to the small but certain reward as probability of the large reward decreased. As a group, aged rats performed comparably to young, but there was significantly greater variance among aged rats. One subgroup of aged rats showed strong preference for the small certain reward. This preference was maintained under conditions in which large reward delivery was also certain, suggesting decreased sensitivity to reward magnitude. In contrast, another subgroup of aged rats showed strong preference for the large reward at low probabilities of delivery. Interestingly, this subgroup also showed elevated preference for probabilistic rewards when reward magnitudes were equalized. Previous findings using this same aged study population described strongly attenuated discounting of delayed rewards with age, together suggesting that a subgroup of aged rats may have deficits associated with accounting for reward costs (i.e., delay or probability). These deficits in cost-accounting were dissociable from the age-related differences in sensitivity to reward magnitude, suggesting that aging influences multiple, distinct mechanisms that can impact cost–benefit decision-making.

Objective To quantify the effect of levothyroxine dose on risk of fractures in older adults. Design Nested case-control study. Setting Population based health databases, Ontario, Canada. Participants Adults aged 70 or more prescribed levothyroxine between 1 April 2002 and 31 March 2007 and followed for fractures until 31 March 2008. Cases were cohort members admitted to hospital for any fracture, matched with up to five controls from within the cohort who had not yet had a fracture. Main outcome measure Primary outcome was fracture (wrist or forearm, shoulder or upper arm, thoracic spine, lumbar spine and pelvis, hip or femur, or lower leg or ankle) in relation to levothyroxine use (current, recent past, remote). Risk among current users was compared between those prescribed high, medium, and low cumulative levothyroxine doses in the year before fracture. Results Of 213 511 prevalent levothyroxine users identified, 22 236 (10.4%) experienced a fracture over a mean 3.8 years of follow-up, 18 108 (88%) of whom were women. Compared with remote levothyroxine use, current use was associated with a significantly higher risk of fracture (adjusted odds ratio 1.88, 95% confidence interval 1.71 to 2.05), despite adjustment for numerous risk factors. Among current users, high and medium cumulative doses (>0.093 mg/day and 0.044-0.093 mg/day) were associated with a significantly increased risk of fracture compared with low cumulative doses (

Community narratives are increasingly important as people move towards an ecologically sustainable society. Global climate change is a multi-faceted problem with multiple stakeholders. The voices of affected communities must be heard as we make decisions of global significance. We document the narratives of long-term anti-nuclear activists near the Three Mile Island (TMI) nuclear power plant who speak out in the dawn of a nuclear renaissance/relapse. While nuclear power is marketed as a “green” solution to global warming, their narratives reveal three areas for consideration; (1) significant problems with nuclear technology, (2) lessons “not” learned from the TMI disaster, and (3) hopes for a sustainable future. Nuclear waste, untrustworthy officials and economic issues were among the problems cited. Deceptive shaping of public opinion, nuclear illiteracy, and an aging anti-nuclear movement were reasons cited for the lessons not learned. However, many remain optimistic and envision increased participation to create an ecologically-balanced world.
