We examine the announcements of high tech mergers using a relatively new proxy for growth options we call “growth to book.” We find this adds significantly to help explain the premiums paid and announcement period abnormal returns when acquiring tech targets. Higher synergies are expected by managers and investors when targets have low growth options and acquirers have high growth options, resulting in higher premiums paid and either less negative or more positive abnormal returns. However, we find significant variation in the results by the relative size of the target and when low growth to book (GTB) firms acquire. While high GTB acquirers tend to pay more in premiums, low GTB acquirers can pay higher premiums and receive some of the most negative returns at announcement. We find evidence some acquisitions are motivated by desperation as these acquirers have the lowest GTB and do a disproportionate number of the relatively largest deals, receiving the worst abnormal returns at announcement.  相似文献

Research with children presents issues beyond those normally encountered in adult exercise science research. This paper explores the specific ethical issues that are encountered when conducting paediatric research in the exercise sciences. We identify the historical, moral and philosophical underpinnings of ethical conduct. The issue of consent and children's ability to provide informed consent is discussed, as is the nature of therapeutic and non-therapeutic research. Finally, we examine the information that is required by a local ethics and research committee and provide guidance material to help in the formulation of an application to such a committee.  相似文献

In baseball and softball, there is a rule that allows the home team to have the last at-bat and thus the final opportunity to win the game. However, in tournament play, this rule is often set aside and, instead, batting order is decided by other means (e.g. tournament rules, the flip of a coin). The purpose of this study was to examine the impact of the batting last rule on game outcome in NCAA men's regional tournament baseball. It was hypothesized that host (i.e. home) teams would win a greater percentage of the games in which they batted last compared with when they batted first. This hypothesis was not supported. Closer examination of the last inning of play showed home teams were no more likely to have won the game during their last bat than visitors playing other visitors. The results suggest that the batting last rule contributes minimally, if at all, to home advantage in NCAA tournament baseball.  相似文献

Sport pedagogy researchers have contributed much to the literature on physical education teaching by describing the participation styles of children, youth and young adults in various settings. The purpose of this study was to describe the participation styles of children enrolled in two consecutive week-long summer adventure camps. Primary participants were 31 elementary and middle school students. Secondary participants were the two adventure educators (AEs) responsible for carrying out all the instruction at the camps. Data were collected using a variety of qualitative techniques and analysed using standard interpretive methods. Nine participation styles were identified indicating that the children in the camps had differing experiences of adventure education and varying degrees of success. Some of the participation styles had similar characteristics to those discovered previously in middle school physical education. Despite these similarities and unlike the middle school setting, there was no indication that a hierarchy of participation styles existed and, consequently, there was no sign of any bullying. Reasons for this difference may well have been the heavy focus on affective objectives within adventure education, much lower student–teacher ratios, higher levels of supervision and management, and greater instructional intent and skill.  相似文献

The purpose of the project reported in this article was to evaluate how assessing teachers’ mathematical knowledge within a professional development course impacted from the teachers’ perspective their learning and their experience with the course. The professional development course consisted of a 2-week summer institute and the content focus was geometry. We had decided to assess the mathematical learning of the teachers during this professional development course for various accountability reasons, but were concerned about possible negative by-products of this decision on the teachers and their participation. Thus, we worked to design assessment in ways that we hoped would minimize negative impacts and maintain a supportive learning environment. In addition, we undertook this evaluation to examine the impacts of the assessment, which included homework, quizzes, various projects, and an examination for program evaluation. Seventeen grade 5–9 teachers enrolled in the course participated in the study by completing written reflections and by describing their experiences in interviews. We learned that while our original intent was “to do no harm,” the teachers reported that their learning was enhanced by the assessment. The article concludes by describing the various properties of the assessments that the teachers identified as contributing to their learning of the geometry content, many of which align with current recommendations for assessing and evaluating grade K-16 mathematics students.

The authors explored the relationship between counselors’ multicultural counseling competence (MCC), poverty beliefs, and select demographic factors. Results of hierarchical linear regressions indicate that MCC is predictive of counselor individualistic and structural poverty beliefs. Implications for counselor multicultural training and immersion and future research directions are included.  相似文献

This article applies the correspondence thesis devised by Bowles and Gintis (1976) to the 1988 Education Reform Act. Theoretical shortcomings of the thesis are identified, and a reformulated version is suggested which incorporates resistances into the analysis of the education system. More limited claims for the thesis are posited. The Education Reform Act is then explored with reference to the revised correspondence principle. Building on the work of previous theorists, it is argued that we may be seeing shifts to post-Fordist education, although contradictions and tensions in this movement are identified. It is suggested that the quasi-market in education is to some extent a change in the legitimating processes of reproduction, rather than a change in what is being reproduced.  相似文献
