Physical Attractiveness and Health in Western Societies: A Review.

Evidence from developed Western societies is reviewed for the claims that (a) physical attractiveness judgments are substantially based on body size and shape, symmetry, sex-typical hormonal markers, and other specific cues and (b) physical attractiveness and these cues substantially predict health. Among the cues that the authors review, only female waist-to-hip ratio and weight appear to predict both attractiveness and health in the claimed manner. Other posited cues--symmetry and sex-typical hormonal markers among them--failed to predict either attractiveness or health (or both) in either sex. The authors find that there is some indication that attractiveness has an overall relationship with health among women, but little indication that male attractiveness relates to male health.

Females' participation in psychopharmacology research as authors, editors, and subjects.

This study determined the involvement of women as first authors and other authors for every article published in Experimental and Clinical Psychopharmacology, Pharmacology Biochemistry and Behavior, and Psychopharmacology in 1991, 1996, 2001, and 2006. Their involvement as editors also was determined. Women's participation as authors, but not as editors, slightly increased over time. In 2006, 43% of first authors, 38% of other authors, and 24% of editors were women. The gender of subjects was examined for the same years and journals, but could not be determined for 6% and 9% of articles employing nonhuman and human subjects, respectively. In 2006, when subjects' gender could be determined, 77% of articles involving nonhuman subjects used only males, 9% only females, and 14% both males and females. In articles using human subjects in that same year, 17% involved only males, 6% only females, and 77% both males and females. Women researchers clearly make substantial contributions to the psychopharmacology literature, but are nonetheless underrepresented as editors. Findings regarding subjects indicate that there is growing recognition of the importance of gender as a determinant of drug effects, although the vast majority of nonhuman studies continue to involve only male subjects.

Fat binding in biscuit wafers

The high degree of fat binding observed in biscuit wafers has been shown to occur as a result of baking and not mixing. In this instance, binding occurs between starch and fat. Evidence is presented that this binding is the result of a physical mechanism in which starch gelatinisation appears to play some role.     

参数测试问题?请在使用检修仪器之前检查探针接触电阻

参数测试仪广泛应用于半导体产品、工艺过程开发以及生产监控。当测试结果与预期不符合的时候,请首先检查信号路径以发现潜在的问题。参数测试系统将电流或电压输入被测器件(DUT),然后测量该器件对于此输入信号的响应。这些信号的路径为:从测试仪通过电缆束至测试头,再通过测试头至探针卡,然后通过探针至芯片上的焊点,到达被测器件,并最后沿原路径返回测试仪器。通常,测量仪器引进一些噪声或测量误差,更可能导致误差的原因是系统的其它部件。在对仪器进行检测前,最好先检查信号路径以发现潜在的问题。其中之一可能是接触电阻,它会受探针参…
