Many areas of public management research are dominated by a top-focused perspective in which emphasis is placed on the notion that managers themselves are usually the best sources of information about managerial behavior. Outside of the leadership literature, managers are also the typical survey respondents in public management studies. An alternative perspective on management can be provided by subordinates’ perceptions of what management is doing. Surveys of subordinates and of managers each pose potential advantages and potential disadvantages when it comes to measuring management, and each approach is likely to prove more fruitful for measuring certain management functions. Using a unique data set of parallel surveys on management with managers and their subordinates as respondents, we examine the differences and relationships between Danish school managers’ and teachers’ perceptions of management functions and the implications of such relationships for organizational performance. We find a surprisingly low correlation between manager and teacher responses regarding the same management functions. Teacher responses are better predictors of student performance for management aspects that are visible to and mediated by teachers. However, manager responses better predict performance for manager expectations that are less visible to employees.  相似文献

Previous work on peer victimization has focused primarily on academic outcomes and negative indicators of youth involved in bullying. Few studies have taken a strength-based approach to examine attributes associated with bullies and victims of bullying. As such, we examined developmental trajectories of moral, performance, and civic character components, and their links to bully status using data from 713 youth (63 % female) who participated in Wave 3 (approximately Grade 7) through Wave 6 (approximately Grade 10) of the 4-H Study of Positive Youth Development. Latent growth curve analyses indicated that moral character was stable across waves, whereas civic character increased slightly by Wave 6. Trajectories for performance character varied; some youth alternatively displayed positive versus negative growth. Youth who reported bullying behavior reported lower initial levels of moral, performance, and civic character as compared to youth not involved in bullying. Bully–victims reported lower initial levels of moral and civic character as compared to youth not involved in bullying. Implications for future work examining character-related components in the context of peer victimization are discussed.  相似文献

ABSTRACT

Youth with ADHD are more at-risk for peer victimization than their typically developing peers, and may not be benefiting from current interventions. Thus, we sought to examine risk (i.e., anxiety, depression, and forms of aggression) and protective (i.e., social skills and social acceptance) factors for peer victimization in this group. Participants were 123 young adolescents diagnosed with ADHD, who were attending grades six through eight. We found that relational aggression (i.e., excluding others from activities) and anxiety symptoms were among the strongest risk factors for victimization. Anxiety symptoms were associated with victimization over and above depressive symptoms. Social acceptance buffered risk conferred by the risk factors. Future work is needed to investigate the degree to which the relations among internalizing symptoms and victimization differ in youth with ADHD relative to typically developing youth, and assess causality of the relations.  相似文献

Pairs of liars and pairs of truth tellers were interviewed and the amount of eye contact they made with the interviewer and each other was coded. Given that liars take their credibility less for granted than truth tellers, we expected liars to monitor the interviewer to see whether they were being believed, and to try harder to convince the interviewer that they were telling the truth. It was hypothesised that this monitoring would manifest itself through more eye contact with the interviewer and less eye contact with each other than in the case of truth tellers. A total of 43 pairs of participants took part in the experiment. Truth tellers had lunch in a nearby restaurant. Liars took some money from a purse, and were asked to pretend that instead of taking the money, they had been to a nearby restaurant together for lunch. Pairs of liars looked less at each other and displayed more eye contact with the interviewer than pairs of truth tellers. The implications of these findings are discussed.  相似文献

Raman spectroscopy for forensic body fluid analysis has received some attention due to the nondestructive nature and potential application for identification at the crime scene; however, its usage has been limited by low detection sensitivity. Surface enhanced Raman scattering (SERS) was evaluated for blood identification for forensic applications. Specifically, a SERS‐active substrate was fabricated, composed of nickel nanotips coated with Ag nanoparticles. Compared with a conventional substrate, the SERS substrate enhanced Raman scattering by more than two orders of magnitude and allowed blood to be identified to a dilution of 1:100,000. Blood was also successfully detected by swabbing the SERS substrate directly on mock evidence. Most importantly, Raman spectra obtained by swabbing the SERS substrate on blood stains were free of luminescence even when blood was deposited on luminescent fabrics. The nondestructive character, simplicity of sample preparation, and high sensitivity make SERS a prime candidate for field and laboratory‐based blood identification.  相似文献

Belgium has one of the most fragmented party systems of any modern democracy. This article asks the following questions: is party fragmentation linked to the importance of the ethno-regionalist vote or to the rules of the electoral system? Has party fragmentation also produced centrifugal or polarised multipartyism (between the regions, but also within Flanders, given the spectacular rise of the Vlaams Blok)? What explains the difference in party fragmentation between Flanders and Wallonia? What are the dimensions of party competition in each community and what are the socio-demographic and attitudinal characteristics of the different electorates? Which steps have the political elites taken to cope with the increasing fragmentation of the party landscape and growing voter volatility? To what extent has the increasing divergence between the regional party systems led to the building of asymmetrical coalitions at the federal and regional levels of government? The splitting of the Belgian party system into two, albeit still fragmented, party systems has further complicated the problems of coordination within a polarised, multi-cleavage and multilevel system that seriously undermines the stability of the entire political system.  相似文献
