University Students’ Attitudes Towards Entrepreneurship: A Two Countries Comparison

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.     

Assessment of Interjudge Reliability in the Open-Ended Questions Coding Process

In the process of coding open-ended questions, the evaluation of interjudge reliability is a critical issue. In this paper, using real data, the behavior of three coefficients of reliability among coders, Cohen’s K, Krippendorff’s α and Perreault and Leigh’s I _r are patterned, in terms of the number of judges involved and the categories of answer defined. The outcome underlines the importance of both variables in the valuations of interjudge reliability, as well as the higher adequacy of Perreault and Leigh’s I _r and Krippendorff’s α for marketing and opinion research.

Ambiguity in election games

We construct a model in which the ambiguity of candidates allows them to increase the number of voters to whom they appeal. We focus our analysis on two points that are central to obtain ambiguity in equilibrium: restrictions on the beliefs that candidates can induce in voters, and intensity of voters' preferences. The first is necessary for a pure strategy equilibrium to exist, while the second is necessary for ambiguity in equilibrium when there exists a Condorcet winner in the set of pure alternatives (e.g. the spatial model of electoral competition), and when candidates' only objective is to win the election. In this last case, an ambiguous candidate may offer voters with different preferences the hope that their most preferred alternative will be implemented. We also show that if there are sufficiently many candidates or parties, ambiguity will not be possible in equilibrium, but a larger set of possible policies increases the chance that at least one candidate will choose to be ambiguous in equilibrium.

农业价值负功能现象的探索

农业价值中普遍存在负功能的现象。其特征是:负功能与正功能互为依存、互为转化,依据不同时间、社会、自然、经济条件而变化,有的事物本身既有正功能,又不可避免地具有负功能,负功能成为事物固有功能的一部分,并对总功能产生影响。研究负功能,有利于防止、克服和转化负功能对事物价值的影响,保持农业可持续发展。     

中国股市调控政策研究--历史、走向与市场影响

“低风险高收益”地利用股市为经济发展服务，无疑是政府股市政策的终极目标。因此，规范和发展将是我国股市政策的永恒主题，只是在不同的发展阶段侧重点不同。股市政策的有效性除受政策本身是否科学、是否得到正确实施等因素的影响外，还受宏观经济政策的影响。股市政策引起股指的短期波动，宏观经济政策的松紧却决定了股指运行的基本走势。
