Kompetenz- und karrieref?rderliches Führungsverhalten: Zum Stand der Forschung

The direct manager which has close contact with his employees is suited to challenge and support them according to their interests and abilities. This paper provides a summary of the empirical literature about the meaning and mechanism of different leadership behaviors influencing employees?? competencies and career advancement. The leader??s behaviors are divided in two ways of support. The direct contact (feedback, training measures, promotion, trust and expectations, objectives?? management, social support, role model behavior) and support by providing competence and career enhancing tasks and job design (delegation of challenging tasks, job control, person-job-fit). Thereby a particular focus is placed upon gender-specific outcomes. Based on the actual research findings, additional recommendations for the career enhancement in practice and for future research are provided.     

关于山西省畜牧业发展的思考

从2000到2006年山西畜牧业取得了较快的发展，畜牧业产值和畜产品产量大幅度增长，但其增长速度仍低于全国平均水平，生产经营分散、养殖规模小，畜牧产业化经营程度低，畜牧业基础设施建设滞后等问题仍然存在。因而，今后要进一步加快畜牧业生产方式转变的步伐，加强畜牧业产业化经营，抓好优势畜产品区域发展和养殖小区建设，同时还要继续摸索更有效的发展途径，保证畜牧业持续快速发展。     

Individual, Family, and Peer Correlates of Adolescent Gambling

The primary purpose of this study was to determine the individual, family, and peer factors that correlate with adolescent gambling. High school students from three states ( N = 1,846) completed an anonymous questionnaire assessing the behavior of themselves, their parents, and their peers. Participants also reported on their gambling behavior via the SOGS-RA, which was used to create five adolescent gambling groups (i.e., Non-Gamblers, Non-Problem Gamblers, At-Risk Gamblers, Problem Gamblers, and Probable Pathological Gamblers). In a discriminant function analysis using demographic, individual, family, and peer factors as potential discriminators, two functions emerged that accounted for 94% of the variance between groups. The first function was linear, with the Probable Pathological Gamblers reporting the highest level of peer and parent gambling, susceptibility to peer pressure, conduct problems, binge drinking, suicide attempts, drug use, and being male. The second function highlighted three unique qualities of individuals in the two outlying groups: Probable Pathological Gamblers and Non-Gamblers. These findings suggest that demographic, individual, family, and peer variables are all important correlates of probable pathological gambling in adolescents. Results also support the utility of a five-group classification scheme based on the SOGS-RA. The clinical implications of these results are discussed.     

The SOGS-RA vs. the MAGS-7: Prevalence Estimates and Classification Congruence

The purpose of this study was to compare the prevalence rate estimates and congruence in classification status derived from two popular measures of adolescent gambling (SOGS-RA and MAGS-7). Adolescents from three states (Alabama, Mississippi, and Oregon) completed an anonymous questionnaire ( n =1846 high school students total). Results indicate that the prevalence of probable adolescent pathological gambling varied both as a function of instrument and cut-off point utilized for classification (range 1.7%-8.2%). Classification groups (non-problem, at-risk, and problem gamblers) generated by both instruments were found to be associated with reports of gambling frequency, amount of money lost in one gambling occasion, and parental gambling problems. However, concern was raised because the MAGS-7 and the SOGS-RA had little congruence in their three-group classification decisions for specific individuals (e.g., only 20.5% agreement for problem gamblers). To improve clinical utility, an empirical case was made for using the SOGS-RA to generate a fourth group of adolescent gamblers, which we labeled "probable pathological gamblers" (SOGS-RA > or = 6). This group was differentiated from the remaining gambling groups on all the validity indices. The implications and limitations of these findings, as well as future directions, are discussed.     

CUSTOMER RACIAL DISCRIMINATION IN MAJOR LEAGUE BASEBALL

Most studies of racial discrimination concentrate on identifying the existence rather than the source of discrimination. In contrast, this paper tests directly for racial discrimination by major league baseball customers by examining the market for baseball cards. In Tobit regressions, the market prices of cards consistently reflect player performance records and other demand variables. When interactive race-productivity variables are included in the models, a significant and complex pattern of fan discrimination against black pitchers and black hitters is found. Discrimination against latin players is not found.
