The correlates of the digital divide and their impact on college student learning

By focusing on two dimensions of the digital divide-computer use and computer knowledge, this study explores four research questions: (1) What are the undergraduates doing with the computers they use at colleges? (2) How do undergraduates perform in regard to computer knowledge and skills? (3) With what is the digital divide among college students correlated? (4) What consequences does the digital divide have for student academic performance? In order to answer these research questions, a national survey was conducted. The survey investigated 3083 first-year college students of 12 4-year universities in Taiwan. A total of 2719 of them completed the questionnaires resulting in a response rate of 88.2%. In this study, the digital divide is measured in terms of computer use, which includes a variety of purposes for using computers and academic-related work as a proportion of total computer hours, and computer knowledge. Multiple regressions and a generalized ordered logit, i.e. a partial proportional odds model, are employed. The main findings include the following: (1) Undergraduates use computers not only for fulfilling their academic requirements and searching for information, but also for entertainment. On average, undergraduates spend about 19h per week using computers, of which 5h are academic-related. (2) Most undergraduates perform at the middle average level in terms of computer knowledge. (3) No significant differences among correlates in relating to demographic and socioeconomic family background were found in predicting the various purposes in using computers. (4) Students who are female, whose fathers and/or whose mothers are from minorities, whose fathers are blue-collar workers or unemployed, who study in the fields of the humanities and social sciences, and who enter private universities are at a disadvantage in terms of computer skills and knowledge. However, female students, students whose mothers were less educated and students who enroll in private universities are more focused computer users in terms of allocating time to academic-related work. (5) Computer knowledge and devotion to using computers for academic-related work have a moderate effect on college student learning, while the various other uses of computers do not. Of the different kinds of computer knowledge, it is the knowledge of software that helps students to learn the most.

Uncertainty and total factor productivity in the Taiwanese banking industry

In this article, we formulate a behavioural model under uncertainty to estimate Total Factor Productivity (TFP) in the Taiwan banking industry. In particular, the article provides a model based on the safety-first rule under uncertainty to measure the risk premium in banking operations that are subject to loan default and other investment risks. With panel data of 40 banks in 1981–1996, a translog cost function and the associated share equations are used to estimate the dual rate of Total Cost Diminution (TCD), the dual Returns To Scale (RTS) and the derived primal rate of TFP. A constant elasticity of transformation output function is employed to construct an aggregated output index of loan and investment activities. The empirical results indicate zero productivity growth and a highly risk-averse banking industry. Government-owned banks are generally more risk-averse than privately owned banks. As expected, the Taiwan banking industry became more risk-venturesome after the deregulation and liberalization of the industry and during the stock market boom of the late 1980s.

QUALITY AND ECONOMIES OF SCALE IN HIGHER EDUCATION: A SEMIPARAMETRIC SMOOTH COEFFICIENT ESTIMATION

This paper proposes a semiparametric smooth coefficient cost model to study the university cost structure where coefficients are an unknown function of the universitys overall quality. A local least square method with a kernel weight function is used to estimate the cost function, and a simple statistic for testing a parametric model of the additive quality versus the semiparametric smooth coefficient model is applied. Empirical results from 56 universities in Taiwan show that, taking quality into account, higher education is subject to diseconomies of scale. In all categories comprehensive and science/technology and public and private universities the current university scale in Taiwan is too big to be cost efficient.
