Abstract While rooted in a tradition stretching back to the late eighteenth century, aerospace museums have enjoyed a period of extraordinary growth over the past three decades. Throughout this period, they have struggled to achieve a balance between their role as “shrines” that celebrate, memorialize and inspire, and “schools” that can help visitors to better understand the complex nature of technological change and its impact on the world. A survey of exhibitions that have sought to portray the history of flight as something more than a story of unalloyed progress, or that depart from traditional master narratives focusing solely on achievement and valor, provides both examples of success and cautionary lessons. If museums of flight are to present a useful and historically accurate portrait of the aerospace enterprise, they must continue the struggle to achieve a balance between these sometimes competing goals.  相似文献

The other articles in this special issue of PIQ deal directly with HPT and its practice. This set of articles does not. It does deal with the relationship between intrinsic motivation and external incentives–questions critical to the practice of HPT. The articles provide reaction to Alfie Kohn's latest book, Punished by Rewards, which ignited something of a firestorm. His article in the Harvard-Business Review, excerpted from the book (Kohn, 1993a) elicited printed responses ranging from reasoned rejoinders to accusations of preaching a brand of communism (Kohn. 1993b). Obviously, right or wrong, he has struck a forest of raw nerves. This set of articles attempts to use Kohn's work as a springboard for exploring the topic of rewards and punishments. It begins with a short review of the book; the review concentrates mostly on Kohn's arguments as they concern the workplace and ignores the large amount of the book devoted to child rearing and schools. The review is followed by two assessments of Kohn's work from the point of view of organizational behavior analysis. They are by Tom Mawhinney of the University of Detroit, Mercy, and Alyce Dickinson of Western Michigan University. Then Richard Pearlstein. the immediate past Vice-President for Research and Development of NSPI, concludes the series by relating the discussion specifically to the way managers actually manage. Our goal in this endeavor is to help lay bare some basic issues underlying human performance in the workplace. We hope you find it useful.  相似文献

This discussion paper focuses on anti-racist groups associated with British Association football (soccer) and the barriers that they face in relation to effective implementation of the anti-racism message and aspirational cultural change. In order to address those issues (above) this essay draws on the educational charity Show Racism the Red Card (SRTRC) and their work to educate individuals in Great Britain though football. It takes an overview of the work of the charity, specifically focusing on three key areas relating to the group’s mission statement. Concluding comments are made on the current position of SRTRC in light of recent high-profile racist incidents.  相似文献

The purpose of this study was to assess how cognitive and physical performance are affected during a prolonged, fatigue-inducing cricket-batting simulation. Fifteen amateur batters from three Eastern Cape schools in South Africa were recruited (mean ± SD: age 17 ± 0.92 years; stature 1.75 ± 0.07 m; body mass 78.3 ± 13.2 kg). Participants completed a 6-stage, 30-over batting simulation (BATEX©). During the protocol, there were five periods of cognitive assessment (CogState brief test battery, Melbourne, Australia). The primary outcome measures from each cognitive task were speed and accuracy/error rates. Physiological (heart rate) and physical (sprint times) responses were also recorded. Sprint times deteriorated (= 0.84; < 0.01) while physiological responses increased (= 0.91; < 0.01) as batting duration increased, with longest times and highest responses occurring in the final stage. Prolonged batting had a large effect on executive task performance (= 0.85; = 0.03), and moderate effects on visual attention and vigilance (d = 0.56; P = 0.21) and attention and working memory (d = 0.61; P = 0.11), reducing task performance after 30 overs. Therefore, prolonged batting with repeated shuttle running fatigues amateur batters and adversely affects higher-order cognitive function. This will affect decision-making, response selection, response execution and other batting-related executive processes. We recommend that training should incorporate greater proportions of centre-wicket batting with repeated, high-intensity shuttle running. This will improve batting-related skills and information processing when fatigued, making practice more representative of competition.  相似文献

University governance reforms: potential problems of more autonomy?   总被引:1,自引:0,他引:1  
University governance reforms are very much a reflection of the broader New Public Management reforms that are focusing on increasing efficiency in public organizations. The article deals with how university reform ideas of a generic nature, emphasizing that universities should be treated and reformed like any other public organizations, are important and reflected in specific reform measures. The special empirical focus is on that universities through reforms are changing their formal affiliation to superior ministries in a more autonomous direction, implicating more autonomy in financial, management and decision-making matters. One the other hand, universities are also through reforms more exposed to more report, scrutiny and control systems, financial incentive systems, pressure to get resources from other sources than the government, cut-back management, etc. So a main question in the analysis is whether universities, as traditionally having quite a lot of real autonomy, through the reforms in fact are getting less autonomy, not more, like the reforms entrepreneurs often are promising. The analysis is based on a transformational approach from organization theory, representing a combination of structural, cultural and environmental factors of explanation for reforms processes and their effects. Empirically the article is based on the author’s own empirical studies of university reform and reviews of comparative studies.  相似文献

Information graphics have become increasingly important in representing, organising and analysing information in a technological age. In classroom contexts, information graphics are typically associated with graphs, maps and number lines. However, all students need to become competent with the broad range of graphics that they will encounter in mathematical situations. This paper provides a rationale for creating a test to measure students’ knowledge of graphics. This instrument can be used in mass testing and individual (in‐depth) situations. Our analysis of the utility of this instrument informs policy and practice. The results provide an appreciation of the relative difficulty of different information graphics, and provide the capacity to benchmark information about students’ knowledge of graphics. The implications for practice include the need to support the development of students’ knowledge of graphics, the existence of gender differences, the role of cross‐curriculum applications in learning about graphics, and the need to explicate the links among graphics.  相似文献
