Feminist scholars the world over are increasingly aware of the importance of analyzing popular discourse, especially regarding women’s involvement in proscribed violence. Yet few have looked at Middle Eastern organizations, and fewer still at the Mojahedin-e Khalq Iran (MEK), a longstanding resistance group whose all-female leadership and sizeable female membership present a compelling challenge to prevailing gender norms. How do popular media portray female MEK resistors and what might these representations signify for our gendered conceptions of violence? In examining the MEK’s female leadership, this article undertakes a close reading of western and Iranian news coverage in an attempt to analyze the degree to which these women are painted as willful political agents or, as is often assumed, irrational actors incapable of autonomous political participation. Following Sjoberg and Gentry, I develop four cognitive frames to describe female resistors, while also challenging the media’s victimizing and sexualizing gaze. I thus problematize these women’s portrayals as “maniacal slaves,” and explain how such gendered rhetoric operates to preclude the notion that members of the MEK might practice legitimate political resistance worthy of analysis or understanding.  相似文献

Children in low-income neighborhoods tend to be disproportionately exposed to environmental toxicants. This is cause for concern because exposure to environmental toxicants negatively affects health, which can impair academic success. To date, it is unknown if associations between air toxics and academic performance found in previous school-level studies persist when studying individual children. In pairing the National Air Toxics Assessment risk estimates for respiratory and diesel particulate matter risk disaggregated by source, with individual-level data collected through a mail survey, this paper examines the effects of exposure to residential environmental toxics on academic performance for individual children for the first time and adjusts for school-level effects using generalized estimating equations. We find that higher levels of residential air toxics, especially those from non-road mobile sources, are statistically significantly associated with lower grade point averages among fourth- and fifth-grade school children in El Paso (Texas, USA).  相似文献

A Bayesian statistical model is developed for analysis of the time-evolving properties of infectious disease, with a particular focus on viruses. The model employs a latent semi-Markovian state process, and the state-transition statistics are driven by three terms: (i) a general time-evolving trend of the overall population, (ii) a semi-periodic term that accounts for effects caused by the days of the week, and (iii) a regression term that relates the probability of infection to covariates (here, specifically, to the Google Flu Trends data). Computations are performed using Markov Chain Monte Carlo sampling. Results are presented using a novel data set: daily self-reported symptom scores from hundreds of Duke University undergraduate students, collected over three academic years. The illnesses associated with these students are (imperfectly) labeled using real-time (RT) polymerase chain reaction (PCR) testing for several viruses, and gene-expression data were also analyzed. The statistical analysis is performed on the daily, self-reported symptom scores, and the RT PCR and gene-expression data are employed for analysis and interpretation of the model results.  相似文献

Abstract

Objective: To conduct a confirmatory factor analysis on the 17-item Sexual Health Survey (SHS), a comprehensive instrument designed to be used with college students. Participants: College students (N = 515) aged 18 to 26 years enrolled at a Midwest public university October 2009. Methods: Confirmatory factor analysis with maximum likelihood estimation was performed to test the stability of the constructs. Results: All factor loadings were significant (p < .001), ranging from .55 to .99 (standardized). The range of squared multiple correlations of items was .31 to .98, and the intercorrelations among the 5 factors were from ?.03 to .52. These small to moderate levels of intercorrelation support discriminant validity of 5 constructs. Conclusions: This study supports the 5-factor version of the 17-item SHS as a viable scale that can measure sexual health overall and 5 distinct areas. College health professionals should consider use of this scale for assessment purposes and evaluation of programmatic efforts.  相似文献

In today’s competitive context, the paradigm of sustainable development is becoming more and more significant, also in warehousing. Managers are progressively considering not only purely economic aspects but also environmental concerns. Despite such consciousness, the selection of automated warehousing solutions has been mainly based on operational and economic performance in both practice and theory so far, whereas energy consumption and environmental performance have not been adequately taken into account. To fill this lack, a model is proposed to evaluate the energy consumption and environmental impact of automated warehousing solutions. The model has been used to investigate whether and how the selection of automated solutions changes depending on the dimensions involved in the analysis (i.e. only economic, only environmental or both). The analysis has been performed considering autonomous vehicle storage and retrieval systems (AVS/RSs) and its natural alternative, i.e. automated storage and retrieval systems (AS/RSs). Results confirm the importance of considering both dimensions in the assessment of automated warehouses, as depending on the scenario, the technology selection shifts from AS/RS to AVS/RS when considering not only the economic but also the environmental impact. Additionally, this study provides new insights on the suitability areas of AVS/RSs.  相似文献

Using nanotechnology as a case study, this article explores (1) how people's perceptions of benefits and risks are related to their approval of nanotechnology, (2) which information‐processing factors contribute to public risk/benefit perceptions, and (3) whether individuals’ predispositions (i.e., deference to scientific authority and ideology) may moderate the relationship between cognitive processing and risk perceptions of the technology. Results indicate that benefit perceptions positively affect public support for nanotechnology; perceptions of risk tend to be more influenced by systematic processing than by heuristic cues, whereas both heuristic and systematic processing influence benefit perceptions. People who are more liberal‐minded tend to be more affected by systematic processing when thinking about the benefits of nanotechnology than those who are more conservative. Compared to less deferent individuals, those who are more deferent to scientific authority tend to be less influenced by systematic processing when making judgments about the benefits and risks of nanotechnology. Implications are discussed.  相似文献

The purpose of this article is to remedy the lack of explanatory endeavours concerning the positive performance of female migrant workers during the recent economic crisis in Western Europe. This phenomenon both interrogates the established association between economic downturns and their negative impact on migrant labour in low‐skilled jobs and enriches the theory of the reserve army of labour, which has been applied to understanding the fragile status of migrant workers in Western economies. Secondary analysis of Labor Force Survey (LFS) and OECD data concerning the impact of the crisis on migrant labour shows that women employed in the care‐domestic sector have been affected significantly less than men employed in manufacture and constructions. To explain this evidence, the article proposes a theoretical framework that draws on key concepts and debates in different strands of sociology: the increasing demand for paid care‐domestic work due to the ageing population and the growth of native‐born women's rates of activity; the commodification of care and the state management of migration; the affectivity and spatial fixity of care‐domestic labour. All these factors contribute to configure female migrant labour, mostly employed in the reproductive sector, as a ‘regular’ rather than a reserve army of labour.  相似文献

This study examined the effectiveness of a nine-week summer emergent literacy program implemented in a Young Men's Christian Association (YMCA) summer program that serves families from low socioeconomic backgrounds. Participants were four- and five-year-old children attending a YMCA summer camp. After being placed in appropriate respective skill-level groups, children received one-hour, daily emergent literacy instruction from their camp counselors, who were trained as novice reading teachers. The teachers used emergent literacy activities to support letter-naming fluency and growth in letter-sound correspondence recognition in addition to mastery of read-aloud texts. The 28 participants experienced positive growth on both dependent measures (letter-naming fluency and letter-sound fluency), indicating the efficiency of the intervention as a tool for improving school readiness for children from low-income families. Additionally, the results suggest that beginning reading teachers may be able to conduct effective emergent literacy instruction, making the intervention replicable. Limitations and associated future research directions are discussed.  相似文献
