This article examines the effect that postsecondary education has on earnings and the duration of time spent in the Social Security disability programs for young persons who are deaf or hard of hearing. Our hypothesis is that investments in postsecondary training increase the likelihood of employment for persons who are deaf or hard of hearing and thus reduce dependency on disability-related income support programs. A longitudinal data set based upon records from the National Technical Institute for the Deaf and Social Security administrative records is used for this analysis. We find that those who graduate, even those who graduate with vocational degrees, experience significant earnings benefits and reductions in the duration of time spent on federal disability programs when compared with those who do not graduate with a degree. This finding suggests that reductions in the duration of time spent on Social Security programs are not limited to those with the highest level of scholastic aptitude and that investments in post-secondary education can benefit a broad group of deaf and hard-of-hearing persons. In addition, the data show that individuals who attend college, but withdraw before graduation, fair no better economically than individuals who never attended college. 相似文献

The number of students studying for university qualifications through the medium of English and for whom English is not their first language has increased significantly in recent years. This, along with efforts to widen access to those under-represented in higher education, has brought into focus the question of what academics see as constituting a ‘good’ piece of student writing. In this small-scale pilot study, Thurstone’s method of paired comparisons was used to establish a scale for ranking six essays in terms of how favourably each was viewed by academic lecturers when compared with every other essay in the set. Kelly’s repertory grid technique was subsequently applied to interviews conducted with the same lecturers to establish which traits they associated with the upper and lower end of the scale. Findings suggest that this methodology represents a promising approach to establishing what academic tutors regard as the key elements of good writing and thus provides an indication of what English teachers might fruitfully focus on in their teaching of the skill. 相似文献

This paper is in the tradition of social analysis aimed at creatingframeworks to join mass media and public opinion processes (e.g.Clarke and Evans, 1983; Gamson, 1975; Gitlin, 1980; Hall, 1977;Iyengar and Kinder, 1987; Lang and Lang, 1968, 1983; Lippman,1922; Mollotch and Lester, 1974; Noelle-Neuman, 1974; Paletzand Entman, 1981; Shaw and McCombs, 1977; Turner and Paz, 1986).After a brief review of media system dependency (MSD) theory,we illustrate how it may apply to public opinion processes thatentail contested issue value-frames (Ball-Rokeachand Rokeach, 1987). In such cases, the media system is directlyimplicated in the negotiation of legitimacy of opposing positionson an issue. Our illustrative case is the abortion issue asit has been played out in the United States over recent decades(Luker, 1984). We focus upon the respective capacities of pro-and anti-abortion movements to control the value-frame of mediacoverage of the issue (Guthrie, 1989). A value-frame may beconceived as ... the main substantive theme of a moralityplay (Ball-Rokeach and Tallman, 1979) wherein the distinctionbetween good and bad hangs in thebalance; in this case, between positions on abortion. We suggestthat change in the value-frame of media coverage and publicdiscourse may be understood, at least in part, as an outcomeof change in contestants' MSD relations. 相似文献

Although previous research has shown the potential of innovative learning for enhancing motivation and learning outcomes, further understanding is needed on which aspects of IL are most effective and whether these are equally motivating for different types of students. The present study investigated how developments in students’ motivation and achievement related to different aspects of innovative learning (i.e. authentic learning, collaborative learning and focusing on self-regulation), and whether these relations varied by students’ background characteristics. A sample of 722 grade five students from the Netherlands (average age 11?years old) and their teachers completed questionnaires during four measurements from grade five to grade six. Autoregression analyses were performed. Results showed both positive and negative relations between IL and developments in students’ motivation and achievement, indicating that IL is not a unidimensional construct. Furthermore, the effectiveness of different aspects of IL depended on students’ gender, and social and ethnic background characteristics. 相似文献

This paper presents a perspective on the capacity of colleges and universities during past and present economic shocks. The
main argument is that the environment of the global recession—an Asia far more economically integrated than during past economic
shocks, with more unified aspirations to be globally competitive and socially responsible—no longer delay reforms in higher
education. In fact, the global recession has become an opportune time for higher education in Asia, specifically developing
countries in eastern (East and Southeast) Asia, to continue reforming governance and administration, access and equity, internal
and external efficiency, and regional collaboration. Economic shocks have accelerated reforms in higher education, especially
those for promoting innovation in their economies, though more is needed in improving governance and access for underserved
populations. This paper examines the cases of China, Mongolia, and Vietnam as examples of how the global recession and regional
integration are growing forces in shaping their higher education reform and development. The paper also identifies a series
of measures for increasing the resilience of higher education systems in serving poor and vulnerable populations during economic
recessions. Responses to the global economic recession by nations in eastern Asia are likely to improve the global shift in
economy and human capital. 相似文献

To prepare a biosynthetic module in an infochemical communication project, we designed a silicon/glass microreactor with anti-adsorption polyelectrolyte multilayer coating and immobilized alcohol acetyl transferase (atf), one of the key biosynthetic enzymes of the pheromone of Spodoptera littoralis, on agarose beads inside. The system reproduces the last step of the biosynthesis in which the precursor diene alcohol (Z,E)-9,11-tetradecadienol is transformed into the major component (Z,E)-9,11-tetradecadienyl acetate. The scope of this study was to analyze and implement a multilayer, anti-adsorption coating based on layer-by-layer deposition of polyethylenimine/dextransulfate sodium salt (PEI/DSS). The multilayers were composed of two PEI with molecular weights 750 and 1.2 kDa at pH 9.2 or 6.0. Growth, morphology, and stability of the layers were analyzed by ellipsometry and atomic force microscopy (AFM). The anti-adsorption functionality of the multilayer inside the microreactor was validated. The activity of His(6)-(atf) was measured by gas chromatography coupled to mass spectrometer (GC-MS). 相似文献
