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

This article chronicles the coordination and better integration of existing institutional resources to support cocurricular themes embedded in the provision of a large enrollment, video‐mediated undergraduate operations management (OM) course. The name Project Cheddarfield refers to a 2008 initiative in which two professors team‐taught an OM course to over 600 undergraduates on two different continents through the repeated rapid exchange of digital video between the United States and Singapore. Simultaneously infused in this core curricular delivery were themes of global awareness and study‐abroad, including the promotion of one particular opportunity that bridged the two campuses. This action research narrative spans over 5 years of related activity leading up to the initiative, as this project is best understood as a trajectory, or the evolving result of design adapting to unfolding realities. 相似文献

It may be concluded that female administrators are perceived as being more adept than their male counterparts for leading innovation in schools and leveraging resources into productive outputs. It may be concluded that both genders of administrators perceive such efforts similarly. The only two skills where gender is significant are the two eornpetencies identified as being alert for new opportunities and synthesizing ideas into focused projects. For the other eight skills indicated in the survey, gender did not play a significant role in such perceptions. 相似文献

The purpose of this study was to discover the perceptions of Florida law school administrators on the impact of the OFI (one Florida initiative) and the addition of two MSI (minority serving institution) law schools on diversity in Florida's legal profession. This research explored the impact of Governor Bush's EO (executive order) on diversity within the SUS (state university system) of Florida law schools. Further, this study examined the impact of the creation of two MSI law schools after implementation of the OFI, as perceived by the administrators. The concept of CRT (critical race theory) provides modern legal debates outlining the usefulness of historical civil rights policies in opinionated climates. This study will examine the role of CRT in relation to affirmative action and desegregation case law. CRT forms the framework for examining the impact of the creation of two MSI law schools in the state of Florida. In conclusion, this study found that minority representation in law schools has improved in Florida as a result of the OFI as well as the addition of two MSI law schools. Black representation, however, continues to lag behind other races, particularly the Hispanic population. This study concluded that the OFI has helped improve minority representation in the legal profession. 相似文献

The aim of this study is to determine fifth-grade students’ metacognitive knowledge and skills and its relationship with mathematics
achievements. A total of 242 primary school students from six different schools were participated in the study. Turkish version
of Metacognitive Knowledge and Skills Assessment (MSA-TR) was used to measure metacognitive knowledge and skills. The results
demonstrated a significant and positive relationship (r = .648, p < .01) between metacognition and mathematics achievement. Furthermore, research results showed that 42% of total variance
of mathematics achievement could be explained with metacognitive knowledge and skills. 相似文献

Although the U.S. population is becoming increasingly diverse, the race of individuals entering the counseling profession remains predominantly White (S. P. Pack‐Brown, 1999). The authors define and explore the connection between White privilege and oppression and encourage the use of racial identity models to address these constructs with counselor trainees in supervision. 相似文献

Both the origin and development of artificial intelligence (AI) are connected with the origin and development of computers. Computers play a very important role in engineering education. AI influences such disciplines like CAD, CASE, CAE, and others. The specific experience concerning AI education at a technical university has been gathered in this paper. There is stressed need of good balance between theoretical background and individual training with computers as well as importance of personal experience in solving practical AI. 相似文献
