Measuring the incidence of public spending in education requires an intergenerational framework distinguishing between what current and future generations—that is, parents and children—give and receive. In standard distributional incidence analysis, households are assumed to receive a benefit equal to what is spent on their children enrolled in the public schooling system and, implicitly, to pay a fee proportional to their income. We show that, in an intergenerational framework, this is equivalent to assuming perfectly altruistic individuals, in the sense of the dynastic model, and perfect capital markets. But in practice, credit markets are imperfect and poor households cannot borrow against the future income of their children. We show that under such circumstances, standard distributional incidence analysis may greatly over-estimate the progressivity of public spending in education: educational improvements that are progressive in the long-run steady state may actually be regressive for the current generation of poor adults. This is especially true where service delivery in education is highly inefficient—as it is in poor districts of many developing countries—so that the educational benefits received are relatively low in comparison with the cost of public spending. Our results have implications for both policy measures and analytical approaches. 相似文献

Pigeons were trained to depress a treadle in the presence of a discriminative stimulus, either a tone or illumination of red houselights, in order to obtain access to grain or avoid electric shock. In avoidance training, the auditory discriminative stimulus yielded faster acquisition than did the visual one. In appetitive training, the visual discriminative stimulus yielded faster acquisition than the auditory one. Experiments 2 and 3 used these stimuli in Kamin’s (1969) blocking design. In Experiment 2, when the pigeons were trained to depress a treadle in the presence of tone to obtain grain and then red light was added as the redundant stimulus, the light acquired stimulus control over treadlepressing; blocking was not observed. In Experiment 3, when the pigeons were trained to depress a treadle in the presence of red light to avoid electric shock and then tone was added as the redundant stimulus, the tone acquired stimulus control over treadle-pressing. Again, blocking was not observed. The implications of these results for several models of stimulus control are discussed. 相似文献

Antireflection is an essential requirement for certain optoelectronic devices. Antireflective surfaces can be generated by different methods. One method mimics the nanofeatures on the moth eye surface. This can be done by ‘soft lithography’ (SL), where nanofeatures are created on an elastomeric stamp. This stamp is then used for imprinting the pattern on other surfaces. 相似文献

University–Industry Collaboration (UIC) has been identified as an essential item on Malaysia’s agenda for transforming itself into knowledge and innovation-based economy. However, despite the efforts, most initiatives have had limited results. This paper reports on an explorative study that sought to understand the contemporary realities of UIC in the Malaysian context. In particular, the study identified the expectations and impediments to UIC, from the perspectives of three groups of stakeholders – the academics, the industry players and policymakers. The findings reveal a number of barriers, including cultural differences, perceived lack of academic expertise and reputation, an inadequacy of institutional policies and regulations, lack of trust, issues of intellectual property rights, and the lack of an appropriate reward system. This paper concludes by proposing policy recommendations and strategies that could be used by the government, university, and the industry to promote further and foster university-industry collaborative opportunities and initiatives. 相似文献

This paper presents the results of a study to determine the effect of the presence of a public junior college in a community upon the types of colleges attended by high school graduates of that community. Results of multivariate cross-tabular analysis of the college destinations of over 8,000 1966 Illinois high school seniors of different sex, ability, and social-status backgrounds living in 25 different communities, suggest that the local availability of a public junior college serves largely to alter patterns of college-going by substituting attendance locally for attendance elsewhere in a manner inversely related to social status. More importantly, results also suggest that among lower- and middle-status persons the substitution is such as to replace attendance at nonlocal four-year colleges with attendance locally at the public junior college. 相似文献

As the director of a small preschool, Mary struggled to come up with a meaningful form of staff development for her teachers. She encouraged her staff to enroll in local workshops, and together they attended weekend-long state and national early-childhood conferences. The staff always returned from these sessions a closer knit group, and the conferences often stimulated them with new ideas that they wished to incorporate into their teaching. Too often, though, by Monday, the demands of the real world of their classrooms had overwhelmed them, and the excitement and energy that had filled them on the weekend had faded away.Dwight Rogers is Assistant Professor, School of Education, University of North Carolina at Chapel Hill.

This article presents an account of the process of development of the NSFNET and its significance for the emergence of the Internet of the 1990s. The fact that the development of the interconnected system of computer networks occurred within the realm of academic research is not incidental. The dynamics of the world of scientific research were intimately related to the shaping of the network and to the way in which it spread to other sectors of society. The construction of computer networks crossed the boundaries between science and society in order to build the scientific realm by transforming the world in which it is embedded. 相似文献
