This study examines the influence of the opportunity costs of school attendance, educational quality attributes, and household socioeconomic status on the educational demand of Mexican Americans, African Americans, and non-Hispanic whites using the 1988–1990 surveys of the National Education Longitudinal Study. Implementing a utility-maximizing framework, educational demand assumes the form of schools' average daily attendance rates and student dropout decisions between the 8th and 10th grades. The basic results suggest that a school's attendance rate is sensitive to educational quality and student characteristics. Moreover, the demand for education measured by student attrition inversely relates to unexplained school attendance, and is positively affected by household socioeconomic status. Some policy recommendations based on the results are discussed.  相似文献

The establishment of the so-called “Norman World” is a debated phenomenon. The influence of the Normans can be found throughout Europe in matters of politics, warfare, and cultural interaction. The empire established by the Normans from the tenth through the thirteenth centuries was based upon the fighting prowess and military might of a people led by notable men such as William the Conqueror and Robert Guiscard. The similarities and differences between the Norman conquests of the eleventh century reveal reciprocity in contact, influence, and exchange among Norman populations. Similarly, the autonomy and distinctness of Norman populations from England to the Mediterranean remained. This article explores the extent of Norman contact, areas of influence and methods of exchange during the most active Norman conquests of the Middle Ages.  相似文献

This is the second of two articles by the same author arguing against the thesis that there was a conspiracy between the Byzantine emperors and Saladin, sultan of Egypt and Syria, against the crusader states and the Third Crusade in the 1180s. While the focus of the first article was primarily on the Latin sources, the present study shifts the focus to the Arabic primary material, hitherto largely neglected or inadequately treated by modern historians. Through a critical re-examination and re-interpretation of the Arabic sources, backed by the introduction and discussion of new Latin material when necessary, this article presents expanded arguments on the relations between the Byzantine Empire, the Sultanate of Konya and Saladin in the 1180s. The conclusions lend further support to the view that the Byzantine rulers and Saladin never concluded an alliance against the Latin settlers of Outremer and the Third Crusade.  相似文献

ABSTRACT

The article describes the functions of the special collection Fond of the Presidents of Ukraine (FPU) within the V. I. Vernadsky National Library of Ukraine, as well as the history of its formation, purpose, activities, and operational features. It emphasizes that the main characteristics of the institution are not only collecting and using various types of documents, but also research and informational-analytical work to popularize them among citizens and authorities. Unlike the US presidential libraries, in Ukraine the conception of the FPU envisages it as an integrated documentary and informational-analytical center to collect heritage materials and study the institution of the presidency as a whole. FPU also provides operative scholarly and informational resources to government officials, to the scholarly community, to the broad student community, and to society in general through the Internet portal of the V. I. Vernadsky National Library of Ukraine and social networks.  相似文献

过去的数字化图书馆和网站的可用性测试通常都集中关注与图形化界面相关的事务以及DL(Digital Library)内部信息的组织,通常忽略了它们在改变工作实践或行为上的作用.本文提出了一种带冲突检测的DL可使用性度量模型CCMM(Conflicting Checked Measuring Model),CCMM在用户使用DL之前采集用户知识水平,并在用户使用DL后对应生成态度改变问题,将用户对这些问题的反应进行FD/I人格特征冲突检测,若未出现冲突,则认为数据真实可靠,可用于DL可使用性度量计算.计算的结果可用于DL优化,最后试验说明CCMM在进行DL可使用性度量上是适用、有效的.  相似文献
