Is the curve relating temperature to aggression linear or curvilinear? A response to Bell (2005) and to Cohn and Rotton (2005)

P. Bell recommended examining the relationship between temperature and assaults during the hottest times of day and during the hottest months of the year. The authors' analyses of these data show a linear rather than inverted U-shaped relationship between temperature and assault during the hottest times of day and in the hottest months of the year. E. Cohn and J. Rotton recommended analyzing the 6 hr with the highest assaults versus the 6 hr with the lowest assaults. During high assault periods, there is a strong positive linear relationship between temperature and assault. During low assault periods, there is no relationship between temperature and assaults. Assaults and other violent crimes might decrease when temperatures are very hot, but the Minneapolis data set does not allow for testing of this hypothesis because Minneapolis is too cold.     

"结构":解读古典经济学哲学构架的逻辑中轴--瓦尔特·本雅明:作品、生活、时代和历史的交叠

马克思的"古典经济学"概念具有明确内涵、外延并与一定的"知识型"相关,这与西方学者在一般的、含糊的意义使用这个概念具有根本的异质性.它界划了一种分析的范式,说明了马克思与资产阶级经济学之间存在着"知识型"的断裂,这种分析范式就是从配第和布阿吉尔贝尔开始的探讨社会结构及由这种结构所决定的运动规律,这是"古典经济学"概念之独特内涵所在.福柯等人忽视了古典经济学的"结构"视角而从"劳动"范畴出发,认为马克思对李嘉图的修正在西方知识的最深层中并未产生真正的间断性,这是没有读懂马克思"古典政治经济学"的真正内涵.

Domestic Violence and Women’s Employment: Fixed Effects Models of Three Waves of Women’s Employment Study Data

Domestic violence can interfere with women’s ability to work, and may result in loss of welfare benefits and poorer economic outcomes. Previous studies showing no effect of domestic violence on employment could be a result of the failure to control for some individual characteristics; therefore we use fixed-effects models with three waves of Women’s Employment Study (WES) data to control for unobservable time-invariant individual-specific characteristics. Included in our analyses were 598 women, from an urban county in Michigan who were on the welfare rolls in February of 1997, all of whom completed 3 waves of interviews. Our fixed effects regression results show that domestic violence significantly reduced the annual work hours of a respondent. Mental and physical health problems do not completely mediate this relationship. Our results support efforts to address domestic violence within the welfare system.     

Development and validation of a self-report measure of emotional intelligence as a multidimensional trait domain

Psychometric review of 33 peer-reviewed studies of six self-report emotional intelligence (EI) measures supports a multidimensional conceptualization of EI. The nature and number of EI facets, however, and their distinctiveness from more established trait domains is unclear. Building on earlier efforts, three studies were undertaken (Ns = 138, 163, 152) to develop self-report measures of 10 facets of EI proposed by Salovey and Mayer (1990). Results support the reliability (internal consistency, test-retest) and validity (content, criterion, construct, structural) of the proposed scales and their distinctiveness among themselves and with respect to more established trait domains (e.g., personality). Specifically, three satisfaction and four cross-cultural adaptability facets were predicted uniquely by 9 of the 10 proposed subscales, controlling for social desirability, the Big Five, positive and negative affect, and self-monitoring. All told, results confirm that trait-EI can be measured using self-report and conceptualized as a distinct multidimensional domain.     

Suicide compared to other causes of mortality in physicians

Physicians frequently are early adopters of healthy behaviors based on their knowledge and economic resources. The mortality patterns of physicians in the United States, particularly suicide, have not been rigorously described for over a decade. Previous studies have shown lower all-cause mortality among physicians yet reported conflicting results about cause-specific mortality such as suicide. In this study, we compared all-cause and cause-specific mortality in a sample of physicians to the age-gender matched general U.S. population from 1948 through 1998. We also compared the mortality experience across medical specialties. The risk of all-cause mortality was 56% lower than expected in men, and 26% lower in women, compared to the general population. Standardized mortality ratios (SMRs) were markedly lower for diseases strongly linked to smoking, e.g., cardiovascular diseases, respiratory diseases, and lung cancer. Suicide was the only cause of death where risk was greater than the general population. Overall, we found that physicians are at substantially lower risk of dying compared to the general population for all causes of death except suicide. The findings for suicide are strikingly different than other causes of death and should provide impetus for new research on the mental health of physicians.     

Amygdala activation to sad pictures during high-field (4 tesla) functional magnetic resonance imaging

Fear-related processing in the amygdala has been well documented, but its role in signaling other emotions remains controversial. The authors recovered signal loss in the amygdala at high-field strength using an inward spiral pulse sequence and probed its response to pictures varying in their degree of portrayed sadness. These pictures were presented as intermittent task-irrelevant distractors during a concurrent visual oddball task. Relative to neutral distractors, sad distractors elicited greater activation along ventral brain regions, including the amygdala, fusiform gyrus, and inferior frontal gyrus. In contrast, oddball targets engaged dorsal sectors of frontal, parietal, and cingulate cortices. The amygdala's role in emotional evaluation thus extends to images of grief and despair as well as to those depicting violence and threat.     

达米特论意义和真

达米特的反实在论意义理论在当代语言哲学中占据重要地位.本文主要分析了他对"意义"和"真"这两个概念的解释,指出他的意义理论完全是一种形式说明,或者说,是对意义理论本身的形式构造.同时,达米特反对用真值条件来解释意义,主要是根据他对"真"这个概念有着不同的理解:他把"真"看作我们在具体场合说出的句子的属性.达米特的思想受到了各方面的批评,他也在这种批评和反批评过程中不断完善自己的思想.
