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

Recent contributions to growth theory stress the importance of localized innovation for the performance of more backward countries. In earlier papers, analyses by means of DEA techniques confirmed this intuition. In this paper, we extend this type of analysis by relaxing the macroeconomic viewpoint adopted until now. New databases on output, labor and capital input in the agricultural and manufacturing sectors are developed for 40 countries. Using intertemporal DEA, it is found that changes in the global production frontier are localized at high levels of capital intensity. This result is stronger in agriculture than in manufacturing. Further, a decomposition of labor productivity growth in eight Asian countries for the period 1975–1992 into the effects of capital intensification, learning and innovation is made. The results suggest that there is a particular development path in which increases in capital intensity appear to be a prerequisite to benefit from international technology spillovers.JEL Classification: O14, O30, O40, O47 相似文献

This article focuses on the structuring of the corporate headquarters in a franchise organization. Four essential issues that are related to franchisors organizational structure are discussed—homogeneity and heterogeneity of franchisors structure, company-owned and franchise arrangement, the dynamics between strategy and structure, and performing innovative and administrative functions simultaneously in the headquarters. Propositions are given for each issue. The results of qualitative analysis associated with each issue are discussed. 相似文献

The Application of Mathematical Programming Approaches to Estimating Container Port Production Efficiency 总被引:1,自引:0,他引:1
Kevin?CullinaneEmail author Dong-Wook?Song Tengfei?Wang 《Journal of Productivity Analysis》2005,24(1):73-92
Container terminal production is both an important and complicated element in the contemporary global economy. This paper aims to evaluate the efficiency of the world’s most important container ports and terminals using the two alternative techniques of Data Envelopment Analysis (DEA) and the Free Disposal Hull (FDH) model. The results give an insight into the current efficiency ranking of the world’s major container ports and terminals. They also confirm expectations that the available mathematical programming methodologies lead to different results and that appropriate variable definition of input and output factors is a crucial element in meaningful applications of DEA and FDH. It is also concluded that the availability of panel data, rather than cross-sectional data would greatly improve the validity of the efficiency estimates derived from all the mathematical programming techniques applied.JEL Classification:C61, D24, E23, L23, L25, L92 相似文献

There is general agreement that attitudes towards the entrepreneur, entrepreneurial activity, and its social function are determinant factors for university students to decide an entrepreneurial career.This empirical study aims at assessing and comparing the attitudes of university students towards entrepreneurship and enterprise formation in Catalonia and Puerto Rico, using a sample of 837 and 435 students, respectively.Results reveal a positive entrepreneur’s image. Both samples have a favorable perception of desirability of new venture creation, although the perception of feasibility is by far not so positive and only a small percentage has the firm intention to create a new company. 相似文献

The last few years have witnessed important advances in our understanding of time preference and social discounting. In particular, several rationales for the use of time-varying social discount rates have emerged. These rationales range from the ad hoc to the formal, with some founded solely in economic theory while others reflect principles of intergenerational equity. While these advances are to be applauded, the practitioner is left with a confusing array of rationales and the sense that almost any discount rate can be justified. This paper draws together these different strands and provides a critical review of past and present contributions to this literature. In addition to this we highlight some of the problems with employing DDRs in the decision-making process, the most pressing of which may be time inconsistency. We clarify their practical implications, and potential pitfalls, of the more credible rationales and argue that some approaches popular in environmental economics literature are ill-conceived. Finally, we illustrate the impact of different approaches by examining global warming and nuclear power investment. This includes an application and extension of Newell and Pizer [‘Discounting the benefits of climate change mitigation : how much do uncertain rates increase valuations?’ Journal of Environmental Economics and Management 46 (2003) 52] to UK interest rate data. 相似文献

We estimate the pro-competitive effects of Austrias participation in the Single Market after its European Union (EU) accession in 1995 in terms of firms market power as measured by the Lerner index, using a sample of 46 industries and 7 industry groups, covering the period 1978–2001. In the framework of the markup estimation method suggested by Roeger (1995), we test for both an instantaneous structural break between 1993 and 1998 and also estimate logistic smooth transition models to take up the proposition that the regime shift is likely to have occurred gradually rather than as a big bang. In sum, the results provide no reason for being euphoric: Pronounced markup reductions were only found in three industry groups (mining and quarrying, wholesale and retail trade; financial services and real estate). At the more disaggregate level, the picture is mixed: Both increases and reductions in market power have been found. 相似文献

Consider N independent stochastic processes \((X_i(t), t\in [0,T])\), \(i=1,\ldots , N\), defined by a stochastic differential equation with random effects where the drift term depends linearly on a random vector \(\Phi _i\) and the diffusion coefficient depends on another linear random effect \(\Psi _i\). For these effects, we consider a joint parametric distribution. We propose and study two approximate likelihoods for estimating the parameters of this joint distribution based on discrete observations of the processes on a fixed time interval. Consistent and \(\sqrt{N}\)-asymptotically Gaussian estimators are obtained when both the number of individuals and the number of observations per individual tend to infinity. The estimation methods are investigated on simulated data and show good performances. 相似文献

The aim of this study was to model and characterize the psychologicalprocesses that underlie the dynamics of global self-esteem and physicalself over time. Twice a day for 228 consecutive days, seven participantscompleted a short inventory (PSI-6, Ninot et al., 2001) measuring sixsubjective dimensions: global self-esteem, physical self-worth, physicalcondition, sport competence, physical strength, and attractive body.Each series was modeled by means of ARIMA procedures. The resultsshowed that a simple moving average model provided a satisfactoryaccount for the dynamics of all series. This model suggests that acombination of two opposite processes underlies the dynamics ofself-concept: preservation, which tends to restore the previousvalue after a disturbance, and adaptation, which tends to inflectthe series in the direction of the perturbation. 相似文献
