试析考迪罗现象形成的必然性及其消亡条件

考迪罗现象是拉丁美洲资本主义生产关系不发达状态在政治上的一种反映 ,是拉美地区社会转型时期阶级矛盾特别是地主阶级与资产阶级矛盾尖锐化的产物。要克服或消灭考迪罗现象 ,除了首先必须铲除孕育它的封建大地产制外 ,最根本的是必须实行彻底的资产阶级民主革命或民主改革 ,大力发展现代化工业和市场经济

University entrepreneurship in a developing country: The case of the P. Universidad Católica de Chile, 1985–2000

Privatization in higher education is usually understood either as the surge of private institutions or as universities’ growing reliance on private sources of funding or otherwise operating more like firms. Joining the growing literature on university entrepreneurship, this is a case study on the less examined problem of entrepreneurial universities in developing countries. In a period of roughly 15 years, the Pontificia Universidad Católica of Chile, founded in 1888, turned itself from a mostly teaching institution to a research-oriented university, responsible for one-fourth of the Chile’s mainstream scientific output and 40% of all Ph.D.s awarded nationally. Yet, public funding represents today only 17% of its revenues, down from almost 90% in 1972. How such academic development could have occurred as the State withdrew and the market took hold of Chilean higher education after the reforms introduced by the military rule of Augusto Pinochet (1973–1990) is the theme of this work. Universidad Católica’s policies and strategies are described, and the factors contributing to its success, together with their limitations, identified. The case suggests that orientation to the market can be more a means for survival and growth under the pressure of privatization, than a result of a ‘Triple Helix’ strategy of universities, government and industry to generate innovation out of academic knowledge. Secondly, while in the industrialized world, higher education entrepreneurship is associated with knowledge production for economic development (‘Mode 2’), entrepreneurial universities in the context of developing countries may just be finding their way to the academic, disciplinary mode of research.

Structural Equation Modeling With Unknown Population Distributions: Ridge Generalized Least Squares

This article proposes 2 classes of ridge generalized least squares (GLS) procedures for structural equation modeling (SEM) with unknown population distributions. The weight matrix for the first class of ridge GLS is obtained by combining the sample fourth-order moment matrix with the identity matrix. The weight matrix for the second class is obtained by combining the sample fourth-order moment matrix with its diagonal matrix. Empirical results indicate that, with data from an unknown population distribution, parameter estimates by ridge GLS can be much more accurate than those by either GLS or normal-distribution-based maximum likelihood; and standard errors of the parameter estimates also become more accurate in predicting the empirical ones. Rescaled and adjusted statistics are proposed for overall model evaluation, and they also perform much better than the default statistic following from the GLS method. The use of the ridge GLS procedures is illustrated with a real data set.
