This study investigated the basic cognitive skills soldiers must possess before entering the Army, skills that are needed for successful completion of entry-level training. Judgments of 126 instructors from 25 military occupational specialties were obtained on 129 candidate skills, which resulted in the identification of 55 basic skills. Factor analysis of these 55 skill items resulted in 11 interpretable factors. Mean scores on the factors were compared across factors and across Army training schools. The results of the study suggest that, for all occupational specialties studied, skills related to the learning process are as crucial as traditional academic skills for successful training course completion. These results have important implications for training for the Army as well as for industry.  相似文献

The is article analyses the two main approaches for artists’ selection in the recording industry: the direct model in which large major companies directly choose new artists from the supply market, and the agency model in which small independent labels realise the first choice and, subsequently, large organisations pick their new artists among those pre-selected by independents.An empirical analysis of chart sales reveals that artists selected through the agency model exhibit a longer presence on the chart due to repeated successes, while they are slower to reach heavy success once they have entered the chart. Conversely, the direct model leads to artists with a faster path to a strong success, but the same artists have a shorter presence on the chart due to the sporadic nature of their success. The profile of artists selected through these two models is also found to be different: big international soloist stars are more frequently selected through the direct model, while national bands are more frequently selected through the agency model.The insights suggest important implications for management in the cultural industries and especially in the recording industry.

Peace movements have shaped national and international culture for decades. Although the Cold War is over, conflict-resolution issues continue to dominate headlines and the news. Peace literature holdings are vital to a relatively young but growing peace and conflict studies curricula. This study uses the list of serials abstracted by Peace Research Abstracts Journal to examine the holdings rates of peace-oriented journal titles in the Association of Research Libraries (ARL) member libraries. Holdings rates are examined by library, title, and subject category. Their impact on scholars, researchers, and students is discussed. Findings reveal generally strong holdings rates among ARL libraries. The broad nature of peace research, however, results in greater variation in holdings among certain important sub-topics of the literature.  相似文献

The lack of widely available, affordable broadband Internet access has spurred a movement in which municipalities are rolling out wireless broadband networks. This movement has raised a number of questions including: Why are municipalities acting as the early adopters of wireless broadband technology? How does increased state regulation of municipal broadband networks affect this trend and how can cities respond? As cities use wireless broadband technology to enhance services to citizens, the growth of municipal wireless deployments has transitioned from linear to exponential. In response, many states have passed laws to regulate and restrict cities' ability to own, operate, deploy, or profit from either telecommunications or information services. Current and pending laws will be examined to understand how cities can deploy a wireless broadband network under these regulations. An analysis of municipal facilities and technology expertise illustrates the opportunity for public–private cooperation in wireless deployments. This paper will show that cooperation is beneficial in many cases. Finally, current business models will be examined for their ability to foster cooperation between the public and private sectors, bridge the digital divide, and create competition among private sector providers.  相似文献

The existence of an information belief system is tested for the first time through innovative use of self moderated focus groups. Initial generation of information beliefs was achieved in an open, unpredicted and unbiased way through focus groups. To remove researcher effect and promote informality in discussion, the researcher experimented with a novel approach - self moderated focus groups. A detailed study of 5 groups evaluates their effectiveness in encouraging free and spontaneous discussion and in eliciting unique information ideas or beliefs. Results show that self moderated focus groups encourage naturalistic discourse, take unpredictable directions and are fertile in uncovering unexpected beliefs. Disadvantages include lack of consistency and leader mirroring, with members adopting the style and tone of volunteer moderators. Consideration should be given to gender balance in group composition. The method is recommended where open and free flowing discussion is sought.  相似文献

This study investigates the convergence of two bibliometric approaches to the measurement of interdisciplinary research: one based on analyzing disciplinary diversity in the reference list of publications, the other based on the disciplinary diversity of authors of publications. In particular we measure the variety, balance, disparity and integrated diversity index of, respectively, single-author, multi-author single-field, and multi-author multi-field publications. We find that, in general, the diversity of the reference list grows with the number of fields reflected in a paper’s authors’ list and, to a lesser extent, with the number of authors being equal the number of fields. Further, we find that when fields belonging to different disciplines are reflected in the authors’ list, the disparity in the reference list is higher than in the case of fields belonging to the same discipline. However, this general tendency varies across disciplines, and noticeable exceptions are found at individual paper level.  相似文献
