不走寻常路，理科生PK文科类重点大学

镜头闪回 想去北京上大学,而且一定要上一所重点大学,一直就是我的心愿。为什么呢？原因其实很简单：北京是首都嘛,从小就在课本和电视里了解了很多。后来在一个假期里,爸爸还带我去玩了一趟。什么颐和园、故宫博物馆,北京就是北京,那才叫一个恢宏大气。而且现在考到北京去念书,正好能赶上2008年奥运会。这个机会可是千载难逢啊!

Incorporating Uncertainty Into Parallel Analysis for Choosing the Number of Factors via Bayesian Methods

A number of psychometricians have suggested that parallel analysis (PA) tends to yield more accurate results in determining the number of factors in comparison with other statistical methods. Nevertheless, all too often PA can suggest an incorrect number of factors, particularly in statistically unfavorable conditions (e.g., small sample sizes and low factor loadings). Because of this, researchers have recommended using multiple methods to make judgments about the number of factors to extract. Implicit in this recommendation is that, when the number of factors is chosen based on PA, uncertainty nevertheless exists. We propose a Bayesian parallel analysis (B-PA) method to incorporate the uncertainty with decisions about the number of factors. B-PA yields a probability distribution for the various possible numbers of factors. We implement and compare B-PA with a frequentist approach, revised parallel analysis (R-PA), in the contexts of real and simulated data. Results show that B-PA provides relevant information regarding the uncertainty in determining the number of factors, particularly under conditions with small sample sizes, low factor loadings, and less distinguishable factors. Even if the indicated number of factors with the highest probability is incorrect, B-PA can show a sizable probability of retaining the correct number of factors. Interestingly, when the mode of the distribution of the probabilities associated with different numbers of factors was treated as the number of factors to retain, B-PA was somewhat more accurate than R-PA in a majority of the conditions.     

Gender and IT in the Household: Evolving Patterns of Internet Use in the United States

Information technology (IT)—computers and related technologies—is the latest technology to enter the household. Like other technologies, gender is a major factor in its adoption and use as well as its perceived usefulness. Unlike prior household technologies, the computer's entry into the household has followed a different pattern. Early statistics revealed a vast gender divide, with men using computers and related technologies much more in the household. More recent statistics show a narrowing of the divide, perhaps even a reversal, particularly in the United States, with women outnumbering men in the access to and use of the Internet. In this article, the role of gender and its relationship with Internet use in the home are reviewed. In addition to overall adoption and access, the review focuses on specific Internet applications and examines the factors that contribute to gender differences in adoption and use of computers and Internet applications in the home.     

Education and European integration

The main purpose of this article is to discuss the implications for education and training of the movement towards integration in Europe in the historic context of the creation of a single market within the European Community (EC) and the end of the Communist regimes in Central and Eastern Europe. The experience of the EC is used to illustrate trends and problems in the development of international cooperation in education and training. Common concerns and priorities throughout the new Europe are then identified and discussed. These include the pursuit of quality in schooling, efforts to serve the interests of disadvantaged learners, and the treatment of European Studies in the curriculum, including the improvement of the teaching of foreign languages.

Zusammenfassung Dieser Artikel stellt die Auswirkungen auf Bildung und Weiterbildung von Bemühungen um die Schaffung eines Gesamteuropas im historischen Kontext eines gesamteuropäischen Marktes und des Endes der kommunistischen Regimes in Ost- und Mitteleuropa dar. Die Erfahrungen der europäischen Gemeinschaft dienen zur Illustration von Trends und Problemen in der Entwicklung internationaler Kooperation in Bildung und Ausbildung. Im weiteren werden gemeinsame Interessen und Prioritäten im neuen Europa identifiziert und diskutiert. Dazu gehöen die Verbesserung der Qualität im Schulwesen, Bemühungen, Belange benachteiligter Schüler zu erfüllen, sowie die Aufnahme europäischer Studien in das Curriculum unter Berücksichtigung einer Verbesserung des Fremdsprachenunterrichts.

Résumé L'intention de cet article est d'analyser les conséquences pour l'éducation et la formation du mouvement vers l'intégration européenne dans le contexte historique de la création du marché unique dans la Communauté européenne (CE) et de la chute des régimes communistes en Europe orientale. Les expériences de la CE permettent d'illustrer les tendances et les problèmes liés au développement de la coopération internationale en matière de l'éducation et de la formation. L'article identifie et examine ensuite les préoccupations et les priorités communes retrouvées partout dans la nouvelle Europe, parmi lesquelles la recherche de la qualité dans l'enseignement, les initiatives prises à l'intention des élèves défavorisés, la place réservée aux études européennes dans le curriculum, et notamment l'amélioration de l'enseignement des langues étrangères.
