全球经济及其理论辨析

由关贸总协定、世界贸易组织、世界银行、欧共体、美洲自由贸易区等国际协定和跨国公司体现的世界经济一体化是由私有化进程和打破区域垄断的自由主义经济目标推动的不可逆转的趋势。在这一过程之中经济和经济学成了世界的结构信息。经济学的两个预设———自私自利的经济人和人的世界———非人世界的二元论是全球经济的深层理论基石。经济人的实践活动造成贫富不均 ,二元论把人溺爱成肆无忌惮地破坏环境的动物。人类应该冷静思索这一新的世界形势 ,提出合理对策     

Barriers to Managing Coronary Artery Disease Among Older Women

Numerous barriers to managing coronary artery disease (CAD) among older women are reported in the literature; however, few studies adjust for demographic and health status differences. A survey assessing barriers and other factors was distributed to a stratified random sampling of older women with CAD. Factor analysis and multiple logistic regression procedures were used to estimate the impact of these issues on receiving a CAD-related office visit. The most problematic barriers included denial and low health literacy. Efforts to promote patient awareness of heart health and better communication between patients and clinicians may alleviate these barriers.     

The Gamma-count distribution in the analysis of experimental underdispersed data

Event counts are response variables with non-negative integer values representing the number of times that an event occurs within a fixed domain such as a time interval, a geographical area or a cell of a contingency table. Analysis of counts by Gaussian regression models ignores the discreteness, asymmetry and heteroscedasticity and is inefficient, providing unrealistic standard errors or possibly negative predictions of the expected number of events. The Poisson regression is the standard model for count data with underlying assumptions on the generating process which may be implausible in many applications. Statisticians have long recognized the limitation of imposing equidispersion under the Poisson regression model. A typical situation is when the conditional variance exceeds the conditional mean, in which case models allowing for overdispersion are routinely used. Less reported is the case of underdispersion with fewer modeling alternatives and assessments available in the literature. One of such alternatives, the Gamma-count model, is adopted here in the analysis of an agronomic experiment designed to investigate the effect of levels of defoliation on different phenological states upon the number of cotton bolls. Data set and code for analysis are available as online supplements. Results show improvements over the Poisson model and the semi-parametric quasi-Poisson model in capturing the observed variability in the data. Estimating rather than assuming the underlying variance process leads to important insights into the process.     

Cognitive-Behavioral Therapy for Bipolar Disorder: Implications for Clinical Social Workers

ABSTRACT

The purposes of this review article are to orient clinical social workers to cognitive-behavioral theory, intervention, and research on bipolar disorder (BD); identify pros and cons of applying cognitive-behavioral therapy (CBT) to social work clients with BD; and identify specific implications for clinical social work practice. Of the 545 articles that were obtained via the systematic review, 18 studies were identified as being potentially eligible for inclusion, and 9 of those studies ultimately satisfied the inclusion criteria. The results of each study were summarized via identifying statistically significant (p< .05) differences that existed between experimental cohorts who received CBT (plus pharmacotherapy) and control cohorts who received treatment as usual. Outcomes showed CBT cohorts as having significant improvement over their respective control groups. The review's implications for clinical social workers and the need for future research are discussed.     

Forging Diaspora: Afro-Cubans and African Americans in a World of Empire and Jim Crow

ABSTRACT

Drawing on social histories of rumour, this article challenges notions of white and Afrikaner homogeneity which persist in the scholarship on late and post-apartheid South Africa. In so doing, it demonstrates the revisionist potential of rumour as a historical source, while reinserting class in a scholarship which privileges race as salient historical feature. The article focuses on Arrie Paulus, apartheid South Africa’s most prominent white trade unionist, infamous as the personification of working-class racism. Yet this defender of race-based privilege and staunch Afrikaner nationalist was haunted by a rumour: Paulus, it was whispered, was not actually white. The rumour circulated in reform-era South Africa and persists in the post-apartheid present. By examining the rumour surrounding Paulus’s racial and ethnic origins in terms of the functions it fulfilled within the particular contexts in which it appeared, this article exposes longstanding tensions around the politics of class characterizing Afrikaner society since the 1970s.
