Latin American youth in the United States tend to report more internalizing symptoms than white non-Latino youth, yet little
is known about the factors that may contribute to such differences. The present study examined the role that anxiety sensitivity,
gender, and ethnic minority status may play in the expression of internalizing symptoms across Latin American adolescents
(n = 116) and white non-Latino adolescents (n = 72) in the United States and Colombian adolescents in Colombia (n = 163). Results provide evidence that because fear of anxiety related phenomena and physiological symptoms of anxiety in
particular may be normative in Latino culture anxiety sensitivity does not amplify somatic complaints for Latin American and
Colombian youth as it does for white non-Latino youth. Results further suggest that anxiety sensitivity and being female predicted
anxiety and depressive symptoms independent of cultural background. Implications of the findings to our understanding of cultural
variability in internalizing symptoms are discussed.
R. Enrique Varela, PhD, is an assistant professor of psychology at Tulane University. He received his PhD from the University
of Kansas Clinical Child Psychology Program. His research interests are cross cultural manifestations of childhood anxiety
and parenting practices in Latin American families. He is also interested in adherence issues in chronically ill children.
Carl F. Weems, PhD, is an associate professor of psychology at the University of New Orleans. He received his PhD from Florida
International University and did post doctoral work at Stanford Medical School. His research focuses on the developmental
psychopathology of anxiety and depression. In particular, his research integrates developmental, cognitive, biological and
behavioral theories in attempting to understand the etiology and course of internalizing disorders in childhood. Special areas
of interest include the assessment and treatment of childhood anxiety disorders, the role of cognitive behavioral development,
brain function, and cognitive processing in anxiety and depression.
Steven L. Berman, PhD, is an assistant professor of psychology at the University of Central Florida. He received his PhD from
Florida International University. His research interests are identity development including associated anxiety and distress,
cross-national comparisons, and the development of identity interventions.
Lauren Hensley, MS, is a graduate student in psychology at Tulane University. Her main research interest is anxiety development,
with a focus on anxiety sensitivity and children’s responses to traumatic events.
Maria Clara Rodriguez de Bernal, MS, is an assistant professor of psychology at Universidad de la Sabana, Bogota, Colombia.
Her research interests are in the area of program evaluation dealing with anxiety disorders, posttraumatic stress disorder
in particular. 相似文献

This article examines the importance of mobility in the historical and ongoing constitution of lesbian and gay subjectivities. While the state in the past frequently sought to restrict the movement of sexual dissidents across national borders, current developments in an array of jurisdictions suggest a more permissive attitude, particularly in the case of the 'unification' of same-sex couples. These legal and political developments are interrogated with respect to the construction of 'acceptable' homosexualities and, more broadly, in terms of cosmopolitan and communitarian visions of sexual citizenship. 相似文献

The Indian economic and political systems have recently opened up for increased foreign investments, which has resulted also in new forms of popular resistance. This article analyzes the campaign launched against the Coca-Cola-Company in Plachimada, Kerala, India, which in 2004 resulted in the closure of its bottling factory after accusations of water depletion and pollution. The analysis in the article is based on the theoretical concept “political opportunity” and concludes that the decision to close the plant was the result of an efficiently run popular campaign based on a tightly knit group of local activists, held together by a tribal identity. Vital for the success was also the help the group attracted by national and international civil society support groups and media, as well as the link between both media and civil society towards the political parties and the state. 相似文献

Most methodological work on project appraisal in developing countries have so far been primarily concerned with industrial projects and distortions in the foreign trade sector.1 In this paper interest is focused on projects in the rural sector and in particular on a neglected aspect of labour cost valuation, viz. valuation of individuals’ work effort expended. 相似文献

Today public administrators, as many others, desire to be known as professionals or those knowledgeable enough to carry out their tasks without outside interference. By examining their claims to have expertise to carry out their public tasks, we provide a critical evaluation of the professionalism of public administrators. Our argument is that public administrators may not have sufficient knowledge to carry out their public tasks without the knowledge (help) of others. Suggesting that public administrators need to have more “public” knowledge of the public interest, we suggest ways that they can become more knowledgeable and more compatible with the tenets of political democracy. 相似文献

Al Qaeda has crafted a successful media strategy that is adeptly suited for the war of ideas against the United States. Osama bin Laden and Ayman al-Zawahiri have demonstrated a great ability to lead plural groups and exploit innovation with the use of technology. This article explores how they have connected with diverse audiences around the world with a constant message. The repetition of their platform themes and use of “message projection opportunities” demonstrate a great understanding of human nature, marketing strategy, global media, and world politics. In line with Prospect Theory, bin Laden and Zawahiri's messaging strategy emphasizes stemming losses over solidifying gains. Only through a better understanding of Al Qaeda's media strategy and all of its strengths, weaknesses, and idiosyncrasies can the United States truly recognize what it is up against and begin to construct an effective and comprehensive counter strategy. 相似文献

Although jihadi nasheeds play an important role in the Islamic State's propaganda, there is scant literature on the topic. This article is an exploratory study on seventeen Islamic State nasheeds released between December 2013 and March 2015. The main argument is that Islamic State nasheeds are effective messaging tools because they focus on a limited number of themes that have broad appeal among Muslims. The nasheeds differ from other Islamic State propaganda in their almost exclusive focus on war and fighting, rather than on the softer sides of life in the Islamic State. 相似文献

Fatal intoxications with opioids are known to be associated with an increased lung weight, as well as with brain and pulmonary edema and urinary retention. However, there is evidence to suggest that fatal intoxications with non-opioid substances are also associated with increased lung weight; however, the latter aspect has not been comprehensively analyzed. To determine to what extent opioid and non-opioid substances are associated with increased lung and brain weight, we studied these organs in cases where the cause of death was attributed to intoxication with a single agent. Using data from cases autopsied at the National Board of Forensic Medicine (NBFM) in Sweden from 2009 through 2019 where the cause of death was attributed to a single substance, we created models of combined lung weight and brain weight. The models used age and sex as predictors as well as nested varying effects for the specific intoxicant and category of intoxicant. Suicidal hanging with negative toxicology cases served as controls. The population majority was male among both intoxications (68%) and controls (83%). The most common single substance group was opioids. All tested substances were associated with heavier lungs than controls, with the largest effect in the opioid group. Our findings show that several substances are associated with increased lung weight and that among intoxication deaths there is no difference in expected brain weight between substances. Hence, heavy lungs, without a reasonable explanation, should prompt a broad toxicological screening. 相似文献
