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

This article reviews the dynamic evolution of personality research and practice in work organizations from the early 1900s through the present. The article reveals steady‐state equilibrium in the world of practice. In contrast, the world of research is shown to be punctuated by rapid changes in conceptual foci, levels of analysis, and methodological approaches, as well as whether or not personality at work is even considered important. Explanations are offered for these trends, including the ways theory and research in the larger world of the study of personality have been reflected in personality research in and on work organizations. The article concludes with some thoughts about revisiting various branches in this evolution and suggestions for the future of personality research and practice in work organizations. © 2007 Wiley Periodicals, Inc. 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

在电网体制改革以及国家政策调整的双重背景下,电力建设市场已经逐渐打破以往的格局,这使电力施工企业不得不参与越来越激烈的市场竞争.但是,由于电力施工企业长期采用粗放的管理模式,人员、材料、机械等各个方面的成本均相对较高,导致其在市场竞争中缺乏优势.对于市场经济来说,企业要想获取竞争优势,主要依靠产品功能和成本两个方面,电力施工企业的产品具有显著的同质性特征,所以成本控制成为电力施工企业提升自身竞争力的主要因素.因此,为了提升电力施工企业的市场竞争力,必须根据实际情况有效落实并不断强化成本管控工作. 相似文献
