Stressful Life Events and Physical and Psychological Health: Mediating Effects of Differentiation of Self in a Spanish Sample

The pathways between differentiation of self and health remain only partly elucidated. This cross‐cultural study sought to test Bowen's hypothesis about the associations between differentiation, stressful life events, and physical and psychological health, in a sample of 466 Spanish adults. Results show that people with higher levels of differentiation were less prone to physical ailments (e.g., heart disease, cancer, or blood disorders) and psychological symptoms (e.g., depression or anxiety). Further, differentiation mediated the association between stress (i.e., perceived negativity of stress in the past year and number of stressful events across the lifetime) and physical and psychological health. The current research provides cross‐cultural empirical evidence for the links between differentiation and mind and body health in a Mediterranean culture.     

Fatigue and sleep quality in nurses

Fatigue is a critical issue for nurses that may lead to medical errors, degradation in performance, decreased mental acuity, and social problems. Poor sleep quality is also a contributing factor in fatigue that nurses experience. Therefore, the purpose of this study was to examine the differences in perceptions of fatigue between night-shift and day-shift nurses, as measured by scores on the Brief Fatigue Inventory (BFI) and to examine differences in sleep quality between the two groups, as measured by responses on the Pittsburgh Sleep Quality Index (PSQI). Univariate analysis of variance showed significant differences between the two groups on the BFI, with the night-shift cohort reporting higher mean scores on the BFI. Significant differences were also found between the two groups on PSQI mean scores, with the night-shift cohort reporting higher mean scores. Findings from this study suggest that night-shift nurses, compared with day-shift nurses, perceived a much higher level of fatigue and had poorer sleep quality. Further research is needed to evaluate interventions that might decrease fatigue in nurses and improve their sleep quality.

Job Skill and Black Male Wage Discrimination*

Objective. Debate over the causes of wage inequality have raised suggestions that, rather than discrimination, skill differences may be the reason for racial wage disparities. The purpose of this research is to examine what impact on‐the‐job skill differences have on wage inequality. Method. I regress the log wage onto race and a measure of skill. The Multi‐City Study of Urban Inequality Employer Survey is particularly useful in this analysis because it contains the employer's evaluation of the worker's relative skill against other workers. Result. When white and black men have the same employer's competitive performance rating, rather than decreasing racial wage differences, the differences actually increase. Conclusion. The wage gap is not a skills gap, but evidence of racial discrimination in the labor market.

Citing history

ABSTRACT

Although rarely considered within the existing scholarship on social movements, even a cursory analysis of protest activity suggests that movements regularly invoke historical citations (whether consciously or not) while working to clarify aims and mobilize constituencies. In order to make sense of this process, and to account for the variations that arise among the different citation modalities favored by movements on opposite ends of the political spectrum, I draw upon the theoretical contributions of Marxist cultural critic Walter Benjamin and, in particular, on his exploration of ‘wish images’ and ‘dialectical images,’ their attributes, and their interrelationship. According to Benjamin, such images summoned the past either to project visions of future happiness (as with the wish image) or to deposit the witness before a moment of decisive, present-tense reckoning. After outlining the role of historical citation in social movements and in the broader cultural field through which these movements find expression, I analyze two recent protest events – the ‘Unite the Right’ rally in Charlottesville, VA, in which wish images were actively deployed, and the 2017 Women’s Strike in New York City, where a dialectical image arose from the constellated nodes of the march’s route – to consider the relationship between citation modality and protest outcome. Following from this analysis, and in keeping with the unapologetically partisan nature of my investigation, I conclude by advancing some strategic recommendations for movements seeking – as Benjamin once enjoined – to ‘improve our position in the struggle against Fascism.’     

The utility of situational theory of publics for assessing public response to a disaster prediction

The study of public response to disasters is a relatively recent discipline that developed following the passage of the Earthquake Hazards Reduction Act of 1977. Because earthquake prediction is an inexact science, few formal predictions have been issued, which has limited the opportunity to study public response to predictions. The purpose of this study was to examine the utility of public relations theory, specifically situational theory of publics, for assessing response to the New Madrid earthquake prediction.Situational theory demonstrates that there is not a single, general public for disaster predictions as has been assumed in studies of disaster response. Instead, multiple publics develop in response to a prediction based on how members of those publics view the situation. Contrary to previous findings that believability and personalized risk are correlated constructs, high personalized risk was associated with high constraint recognition regardless of belief in the prediction. Based on the findings, suggestions are proposed for the development of more effective messages for communicating with publics at risk.     

Progesterone: the forgotten hormone in men?

‘Classical’ genomic progesterone receptors appear relatively late in phylogenesis, i.e. it is only in birds and mammals that they are detectable. In the different species, they mediate manifold effects regarding the differentiation of target organ functions, mainly in the reproductive system. Surprisingly, we know little about the physiology, endocrinology, and pharmacology of progesterone and progestins in male gender or men respectively, despite the fact that, as to progesterone secretion and serum progesterone levels, there are no great quantitative differences between men and women (at least outside the luteal phase). In a prospective cohort study of 1026 men with and without cardiovascular disease, we were not able to demonstrate any age-dependent change in serum progesterone concentrations. Progesterone influences spermiogenesis, sperm capacitation/acrosome reaction and testosterone biosynthesis in the Leydig cells. Other progesterone effects in men include those on the central nervous system (CNS) (mainly mediated by 5α-reduced progesterone metabolites as so-called neurosteroids), including blocking of gonadotropin secretion, sleep improvement, and effects on tumors in the CNS (meningioma, fibroma), as well as effects on the immune system, cardiovascular system, kidney function, adipose tissue, behavior, and respiratory system. A progestin may stimulate weight gain and appetite in men as well as in women. The detection of progesterone receptor isoforms would have a highly diagnostic value in prostate pathology (benign prostatic hypertrophy and prostate cancer). The modulation of progesterone effects on typical male targets is connected with a great pharmacodynamic variability. The reason for this is that, in men, some important effects of progesterone are mediated non-genomically through different molecular biological modes of action. Therefore, the precise therapeutic manipulation of progesterone actions in the male requires completely new endocrine-pharmacological approaches.

建设海峡西岸社会主义新农村的价值选择

建设社会主义新农村,本质是要缩小城乡差距,使农村在加速工业化、城市化的过程中能够与城市共同协调发展,使农民与城市居民一样享受等值不同质的现代生活。以等值不同质为取向增进农民福祉,是海峡西岸社会主义新农村建设的出发点和落脚点。建设海峡西岸社会主义新农村,要树立大资源观,以增量资源为杠杆激活存量资源,构建平等、互动、共福的新型城乡关系。
