In this paper the objectives of a new international research project that focuses on the perception of leadership across cultures will be presented. The definition of leadership will be discussed in relation to cross-cultural leadership research. The ideas and theory on which the project is based will be introduced along with several of the hypotheses the project is designed to test. Besides testing the general hypotheses, results obtained in the GLOBE study can also be used for a more focused comparison between two countries. In this paper, differences in preferred leadership attributes and national culture dimensions in The Netherlands and Poland are presented. A total of 287 Dutch managers from six organizations and 277 Polish managers from six organizations filled out questionnaires. The results indicate that Dutch and Polish cultures differ strongly on power distance, uncertainty avoidance and future orientation. Regarding preferred attributes for outstanding leadership, Polish respondents score especially high on administrative skills, vision, and diplomacy, whereas Dutch managers emphasize integrity, inspirational behavior and vision. Polish respondents are also less negative about autocratic leadership. 相似文献

Twin and adoption studies have demonstrated a significant contribution of both genetic and environmental factors to antisocial and delinquent behavior. Associations have been reported between the serotonin transporter (5‐HTT) and aggression, and between socioeconomic status (SES), aggression, and serotonergic functions of the brain. We aimed to investigate associations between the 5‐HTTLPR genotype and family SES in relation to delinquent behavior among adolescents. A total of 1,467 17‐ to 18‐year‐old students in the county of Västmanland, Sweden, anonymously completed a questionnaire and gave a saliva sample. Family SES had a U‐shaped relation to delinquency, where adolescents with low and high family SES were the most delinquent. There were curvilinear interactions between the 5‐HTTLPR genotype and family SES in relation to delinquency. Among individuals having high family SES, boys with the LL (homozygous for the long allele) or LS (heterozygous) genotypes and girls with the SS (homozygous for the short allele) or LS (heterozygous) genotypes showed the highest delinquency scores. Among individuals having low family SES, boys with the LL (homozygous for the long allele) genotype and girls with the LS (heterozygous) genotype showed the highest delinquency scores. The present study suggests evidence for an interaction between family SES and the 5‐HTTLPR genotype in relation to juvenile delinquency. Aggr.

Figure-ground organization of an ambiguous pattern can be manipulated by the spatial and temporal frequency content of the two regions of the pattern. Controlling for space-averaged luminance and perceived contrast, we tested patterns in which the two regions of the ambiguous pattern contained sine-wave gratings of 8, 4, 1, or 0.5 cycles per degree (cpd) undergoing on:off flicker at the rates of 0, 3.75, 7.5, or 15 Hz. For a full set of combinations of temporal frequency differences, with each spatial frequency the higher temporal frequency was seen as background for more of the viewing time. For two spatial frequency combinations, 1 and 4 cpd, and 1 and 8 cpd, tested under each of the four temporal frequencies, the lower spatial frequency region was seen as the background for more of the viewing time. When the effects of spatial and temporal frequency were set in opposition, neither was predominant in determining perceptual organization. It is suggested that figure-ground organization may parallel the sustained-transient response characteristics of the visual system. 相似文献
