The underlying “architecture of the decision to pursue a degree in psychology was quantified using the Method of Sorting technique
to identifying the critical issues necessary to make this choice. Multidimentsional scaling procedures were employed to construct
a three-dimensional map representing the relationships between reasons for selecting psychology as a major. Freshman and senior
psychology majors (N = 165) from a regional university and a large research-based institution rated the relative importance of items in their
decision-making process. Hierarchical clustering procedures revealed seven different groups of students. Although significant
differences associated with class standing were not found, institutional affiliation did influence cluster composition. Reflecting
local emphases, students at the regional institution had a greater interest in Counseling Psychology, whereas those at the
research-based school focused on Clinical Psychology. This semantic map and the associated item clusters arising from psychology
student data provides an empirical basis for, amongst other things, course selection, faculty-initiated program design or
revision, strategic niche marketing, and student retention. 相似文献

The dynamic relationship linking the volatility of equity prices with “the news” and the expected path for monetary policy
is investigated. Previous results that link the impact of the news about real activity to changes in current and future interest
rates are employed in developing a positive link between changes in volatility and the news. Empirically, our results uncover
a positive and statistically significant response of the CBOE volatility index, VIX, to unanticipated changes in employment,
but not to inflation. Hence, agents' expectations for the policy response to news have an important influence on the expected
volatility of stock prices. (JEL E44, E52) 相似文献

The paper considers the main threats and opportunities for SMEs in new member states, arising out of EU membership, including the implications for SMEs at the micro level. Whilst accession-related changes have important potential implications for firms of all sizes, the distinctive size-related characteristics of SMEs affect their ability to identify, cope with and respond to new sources of threat and opportunity. These potential impacts face new member countries at a relatively early stage in the development of market-based systems, which still contain many deficiencies (particularly in institutional terms) and a SME sector with many characteristics that reflect its fledgling status. 相似文献

This paper reports on a study to compare self-reports during an interview with staff who attended a University health centre in Turkey, with the records of visits to the same health centre over the previous 12 months. Design of the study reflects the effects of importance of the event, duration since the event, frequency of the occurrence of the event, measurement scale of the event, and bounded and unbounded recalling. In order to assess the extent of recall error, responses to retrospective questions on health centre visits are compared with administrative records. Statistical models are proposed for short and long term human memory recall error effects on responses. 相似文献

In investigating the causal relation between government revenue and spending, our empirical results support the tax-and-spend
hypothesis for Egypt and the fiscal synchronization hypothesis for Jordan. Breaking away from these historical trends is essential
for both countries to eliminate the budget deficit and therefore ensure the availability of domestic saving for private investment.
To cope with unemployment and poverty, continuing privatization is recommended for both countries to improve productivity
and efficiency in the domestic economy. Privatization should lead to higher domestic saving and investment and at the same
time eliminate the budget deficit by enhancing revenue and curbing spending. (JEL H62, H63) 相似文献

We consider a model of an oligopolistic market with heterogeneous firms and products where neither the cost nor the demand functions are common knowledge. Instead, each firm only has some vague ideas about the price strategies adopted by its competitors which is modelled by a fuzzy set. In analogy to the notion of an "equilibrium of actions and beliefs" we define and characterize a generalized Nash-equilibrium and show its existence under general conditions. Furthermore, the impact of the fuzzy information on the equilibrium outcome is analyzed by means of a comparative static analysis within a particular model framework.Received: 28 May 2002, Accepted: 25 December 2002, JEL Classification:

In this paper, we consider the problem of estimating a selected set of contrasts between v treatments using a block design consisting of b blocks of size k. Traditionally, the construction of A-optimal block designs for such situations has been carried out assuming a fixed effects model. In this paper, we show that A-optimal designs constructed under a fixed effects model are robust in the sense that these designs have maximal minimal efficiency when considered among all available designs and under all possible mixed effects models.

Prior research has employed a number of methods to test for speculative bubbles in asset prices, including a method based
on the concept of duration dependence. This study explores whether duration dependence tests for speculative bubbles are sensitive
to specification decisions. Our results question the efficacy of using measures of duration dependence to test for speculative
bubbles. In particular, we find that evidence of duration dependence is sensitive to the method of correcting for discrete
observation of continuous duration, the use of value-weighted versus equally weighted portfolios, and the use of monthly versus
weekly runs of abnormal returns. (JEL C41, G12) 相似文献

中国政策性创业资本的地位及定位研究 总被引:1,自引:0,他引:1
张志民 《首都经济贸易大学学报》2004,6(6):50-53
文中将创业资本划分为政策性创业资本与商业性创业资本,提出政策性创业资本不应以追求商业利润或与私人部门分享利润为目标,而是以税收、就业、区域发展、出口和经济发展作为追求目标。它应该承担起更多的社会功能,政策性创业资本的定位就在于通过国家宏观政策方面的调节来分散、分担商业性创业资本的经营风险,吸引、引导、鼓励、扶持商业资本进入创业投资领域。 相似文献

社会主义经济是信用经济,没有信用,就没有秩序,市场经济就不能健康的发展。加强企业信用管理的风险控制是现代企业的一项重要任务。进入WTO标志着中国经济更加开放,国际贸易更加纷繁复杂,在机遇透人的同时,企业也潜伏着越来越大的风险,尤其是企业信用风险。因此强化企业的信用风险管理,建立与完善企业内部信用风险管理体制,仍然是企业面临的一项重要课题,笔者从多方面阐述了企业信用风险形成的原因以及如何建立风险管理机制等问题。 相似文献
