Facial Appearance, Gender, and Emotion Expression.

Western gender stereotypes describe women as affiliative and more likely to show happiness and men as dominant and more likely to show anger. The authors assessed the hypothesis that the gender-stereotypic effects on perceptions of anger and happiness are partially mediated by facial appearance markers of dominance and affiliation by equating men's and women's faces for these cues. In 2 studies, women were rated as more angry and men as more happy-a reversal of the stereotype. Ratings of sadness, however, were not systematically affected. It is posited that markers of affiliation and dominance, themselves confounded with gender, interact with the expressive cues for anger and happiness to produce emotional perceptions that have been viewed as simple gender stereotypes.

Micro Semi‐solid Manufacturing ‐ A New Technological Approach towards Miniaturisation

One of the most important prerequisites to meet the increasing demand for efficient technologies for micro‐part production is constituted by the ability to overcome existing process limitations by new innovative technological approaches. By the introduction of a new process variant based on a hybrid material condition between solid and liquid state, such an approach is presented. This micro semi‐solid manufacturing technology, so‐called Micro‐Thixoforming, was initiated, on the one hand, by being aware of the technological limits of existing micro‐forming and micro‐casting processes and, on the other hand, by a comprehensive understanding of the special rheological mechanisms of metallic materials in semi‐solid state finally establishing the desired potential to follow the trend towards miniaturisation with drastically reduced process restrictions. However, this promising potential can only be successfully exploited when the initial idea, which is based on phenomenological considerations, can be transferred to a process technology with sufficient practical relevance. Therefore, the presented new integrated process concept for Micro‐Thixoforming is particularly characterised by the application of unconventional solutions for the main process steps: raw material conditioning, thermal pre‐processing, semi‐solid forming and thermal post‐processing. To give an indication of the innovative character of the chosen practical solutions liquid metal jet technology, LASER‐induced plasma shockwaves and high pressure water jet should be mentioned. However, what is even more important in this context is the ability not only to realise a process concept but, beyond that, to recognise the further potential regarding new strategies for material design arising from the availability of this process. Such a strategy e.g. consists of utilising the well‐known segregation effect, which notably often is negatively associated with semi‐solid forming. However, for the envisaged technological approach, controlled segregation aims at a defined adjustment of functionally graded properties for the produced micro part.     

Looking back and looking ahead: Adult age differences in consistency of diachronous ratings of subjective well-being.

The goal of this study is to investigate the consistency of diachronous ratings of subjective well-being (SWB). A heterogeneous sample (25-74-year-olds; N=3,596) provided ratings of their present SWB, reconstructed their SWB of 10 years ago, and anticipated their SWB 10 years from now. Developmental tasks and self-evaluative principles were used to predict age differences in diachronous consistency. As predicted, in young adulthood, past SWB was rated lower and future SWB higher than present SWB. In contrast, in later adulthood, the past was rated higher and the future lower than present SWB. Analyses of rank-order consistency demonstrated that in later adulthood both future and past SWB were more strongly related to present SWB than in young adulthood. Results show how models of self-evaluation play out at different points in the life span. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Effectiveness of products from four locally grown plants for the management of Acanthoscelides obtectus (Say) and Zabrotes subfasciatus (Boheman) (both Coleoptera: Bruchidae) in stored beans under laboratory and farm conditions in Northern Tanzania

The effectiveness of whole or powdered leaves (botanicals) from four locally grown plant species applied at a rate of 1.5 kg per 100 kg beans (Phaseolus vulgaris) against Acanthoscelides obtectus and Zabrotes subfasciatus was compared under laboratory and farm conditions. In the laboratory, Chenopodium ambrosioides, applied as powder or as whole leaves, was the most effective, with 100% mortality of adult insects in less than three days and no progeny. Less C. ambrosioides (about 200 g per 100 kg beans) still resulted in 100% mortality within 24 h. Tagetes minuta applied as powder also increased mortality and reduced oviposition and progeny production significantly. The other treatments - T. minuta applied as leaves, and Azadirachta indica or Cupressus lusitanica applied as powder or as whole leaves - had no significant effects upon mortalities, oviposition rate, or progeny production compared with control treatments. When the rate of application was increased to about 8.3 kg per 100 kg beans, there was a slight increase in mortality using T. minuta and A. indica, but not with C. lusitanica. An additional trial with C. ambrosioides from different collections and with plants at different stages of development revealed considerable variations in the efficacy of the treatment.In the on-farm trials, A. indica-seed powder was the most effective treatment, followed respectively by leaf powders of C. ambrosioides, C. lusitanica and T. minuta. All treatments were significantly more effective than the control in reducing the numbers of live insects; they also reduced numbers of damaged beans and maintained germination rates after 5 months of storage. The results of evaluations of the treatments made by farmers just after the trials and five years later are reported.

College counseling center internships: Clarifying the issues.

Clarifies the following issues raised by F. J. Dorn (1984) in an article about college and university counseling centers: (1) differentiation between year-long (12 mo) and American Psychological Association (APA)-accredited internships, and (2) understanding of the current (1979) APA Criteria for Accreditation. It is argued that in any discussion of nonapproved programs, it is essential to differentiate between non-approved programs that are psychology programs vs programs in other fields (i.e., counseling).
