Corporate restructuring was identified as a new industrial force that has great impact on economic values and that therefore has become central in daily financial decision making. This article investigates the optimal restructuring strategies under different dynamic factors and their numerous impacts on firm value. The concept of quasi-leverage is introduced and valuation models are built for corporate debt and equity under imperfect market conditions. The model's input variables include the quasi-leverage and other firm-specific parameters, the output variables include multiple corporate security values. The restructuring cost is formulated in the form of exponential function, which allows us to observe the sensitivity of the variation in security values. The unified model and its analytical solution developed in this research allow us to examine the continuous changes of security values by dynamically changing the coupon rates, riskless interest rate, bankruptcy cost, quasi-leverage, personal tax rate, corporate taxes rate, transaction cost, firm risk, etc., so that the solutions provide useful guidance for financing and restructuring decisions.  相似文献

事业的长期停滞常由于基本理论的失误。我国足球长期奉行的基本理论,在自然体育学方面,就是体能与技战术分家而以体能为基础;在社会体育学方面,就是用行政手段统一全国训练方法的大框架。从足球建设丰富的经验教训来看,一些重大的学术问题已经提到面前,需要研究解决。在这个基础上形成进步的战略决策,中国定圆足球梦。  相似文献

In soccer, home teams win about 67% of decided games. The causes for this home advantage are still unresolved. There is a shortage of research on the psychological states of actors involved. In this study, we examined soccer coaches’ expectations, goal setting and tactical decisions in relation to game location. Soccer coaches (N = 297) with different expertise levels participated in an experimental, online management game and were randomly assigned to one of two groups, “home game (HG)” or “away game.” Participants received information on the game for which they were asked to make decisions in multiple points. The only differing information between groups was game location. Regardless of expertise, HG coaches had higher expectations to win, set more challenging goals and decided for more offensive and courageous playing tactics. Possible consequences of these findings concerning home advantage in soccer are discussed.  相似文献

Peer-teaching is widely established in anatomy teaching and offers well-described advantages. Nevertheless, at Ulm University, Germany, a reduction in the number of peer teacher applicants for the dissection course was observed. This study examined factors related to the attractiveness of a position as a peer teacher for Generation Z students. Participants of the gross anatomy course were asked to evaluate factors influencing the attractiveness of a peer teacher position using a six-point Likert scale. Additionally, open-ended questions were analyzed qualitatively. Sex-specific subgroup analysis was performed comparing students of low and high motivation to apply for a tutorship. Of the 374 students who participated in this study (response rate 53%), 38% stated that they were intending to apply as peer teachers. Data indicated that students displayed intrinsic motivation to apply for a tutorship because of the opportunity to improve their anatomy knowledge and/or their pleasure in teaching. In contrast, extrinsic factors like remuneration of the tutorship and its relevance for their curriculum vitae were least important. Anatomy educators underestimated the demotivating factor of the workload associated with the tutorship and encouraged students less frequently to apply than peer teachers. Only minor sex-specific differences could be identified. Nevertheless, female students were encouraged less frequently to apply than their male peers. In summary, Generation Z students apply as peer teachers because they are enthusiastic about the task. To motivate students to commit to extracurricular activities like a tutorship, anatomy educators should actively encourage students—particularly females—more frequently to apply.  相似文献

Employers’ recruitment behaviour in entry labour markets is central for young people’s transitions from school to work. Whereas previous research has focused on the effects of specific applicant characteristics, I concentrate on how organisational characteristics, namely organisation size and private or public sector affiliation, relate to selection decisions in the dual apprenticeship system in Germany which is a major entry labour market. Following organisational and institutional theory, I expect early selection stages to be more open at larger and public organisations in contrast to smaller private organisations. I also investigate how different organisations respond to school grades as applicants’ signals of skills. I use field experiment data combining organisational-level and applicant-level data to analyse how actual employer responses to written applications by fictitious young people vary with organisation type. The results indicate that, net of applicant characteristics and occupation-specific practices, applications are more likely to receive an invitation to a follow-up selection stage if submitted to larger organisations, and especially larger public organisations, rather than to smaller private organisations. This finding extends to applicants with poorer school grades. Public sector affiliation, however, did not seem to matter much within the group of smaller organisations.  相似文献

被引频次可以客观反映科技期刊被使用和受重视的程度,已成为许多机构评价科技期刊的重要指标之一。提高期刊被引频次是编辑决策面临的首要问题。借助《中国知网》,采取手工检索和自动检索相结合的方法逐期逐篇登记,对《衡阳师范学院学报》(简称《学报》)2010—2012年的261篇自然科学论文进行被引频次统计分析。结果表明环境科学与资源科学被引频次比值较高,对《学报》评价有着积极影响,而教学论文发文量大,但被引率低,给《学报》评价带来消极影响。从作者职称、学历情况看,教授与博士的论文被引频次比值最大。继续依托校内重点学科与省级平台是《学报》提高被引频次的重要途径;此外,要积极争取知名学者的稿件,提高国家级基金论文比例,努力提高《学报》论文质量以实现被引频次大幅上升的目标。  相似文献
