Hyperhomocysteinemia (HHCY) has been demonstrated to affect cochlear microvasculature as well as cochlear epithelial cells directly, with a resultant alteration of the expression of matrix metalloproteinases (MMPs) and their inhibitors, tissue inhibitors of metalloproteinases (TIMPs). Hence, ascertaining the optimum concentration of MMPs and TIMPs in the cochlea could help to inhibit hearing loss due to HHCY by the administration of appropriate MMP inhibitors, Since infections/inflammations as well as ototoxic antibiotics have a similar mechanism of otic pathology, the cochlear damage they cause could also be similarly prevented. 相似文献

The study described in this article takes the view that distance education programs are dynamic systems with multiple constituencies.
Literature on distance education programs as complex systems and on the critical constituency approach to program evaluation
was used to guide the development of a questionnaire designed to assess the components of a distance education program. Instrument
development was conducted in four phases using both quantitative and qualitative methods. The data from this study suggest
that there are four major components of effectiveness in distance education programs: instruction, management, telecommuting,
and support. Within each of these components there are from two to five subcomponents, 14 components in all, which can be
used to assess distance education programs. The assessment scale which was developed measures these four components and their
subcomponents. 相似文献

Abstract The objective of this study was to examine the chronic effects on strength and power of performing complex versus traditional set training over eight weeks. Fifteen trained males were assessed for throw height, peak velocity, and peak power in the bench press throw and one-repetition maximum (1-RM) in the bench press and bench pull exercises, before and after the eight-week programme. The traditional set group performed the pulling before the pushing exercise sets, whereas the complex set group alternated pulling and pushing sets. The complex set training sessions were completed in approximately half the time. Electromyographic (EMG) activity was monitored during both test sessions in an attempt to determine if it was affected as a result of the training programme. Although there were no differences in the dependent variables between the two conditions, bench pull and bench press 1-RM increased significantly under the complex set condition and peak power increased significantly under the traditional set condition. Effect size statistics suggested that the complex set was more time-efficient than the traditional set condition with respect to development of 1-RM bench pull and bench press, peak velocity and peak power. The EMG activity was not affected. Complex set training would appear to be an effective method of exercise with respect to efficiency and strength development. 相似文献

This point of departure presents the writings of a White, female teacher educator’s experiences in the academy. Through the use of vignettes, the author discusses how four recent experiences – and her writing about those experiences – reveal the insidiousness of silence and Whiteness in the academy. 相似文献

In this paper, the so far hardly explored history of empirical educational research (Bildungsforschung) in West Germany between 1945 and the 1990s is examined and roughly surveyed. The focus is on the 1950/1951 established German Institute for International Educational Research (DIPF) in Frankfurt on the Main, whose foundation was closely linked to the policy of the US occupation forces in Germany. Also considered is the history of the Berlin Max Planck Institute for Human Development (MPIB), which was founded in 1963. It is suggested that the Frankfurt institute was a pioneer of educational research and that its foundation took place quasi-necessarily as a non-university institute due to the political and scientific context conditions at the time. Therefore, the history of the MPIB can be understood adequately only on the background of the DIPF’s history and the further development of educational research should be analyzed with special regard to the specific conditions of non-university research in Germany. Looking ahead, the desideratum of a transnational history of empirical educational research in West Germany is outlined which basically fathoms the development of science as a result of complex interactions with other social knowledge and action fields. 相似文献

In this article, two teacher educators reflect on their experiences teaching a diversity course for preservice middle-school teachers. The first author is an African American male teacher educator, and the second author is a White female teacher educator. While the authors bring distinct experiences, backgrounds, and epistemologies to this work, both seek to prepare preservice teachers with the skills and dispositions needed to meet the needs of culturally diverse students. Including their narratives in their own words, the authors share their experiences teaching this course and make recommendations for those doing this work in their respective spaces. 相似文献

Administrators, instructors, students, and employers need to know the essential concepts taught in occupational courses. In particular, instructors require this information in order to avoid some common teaching traps and to avoid establishing a series of cumulative deficiencies for their students. To provide this information, community college accounting instructors performed a forced Q‐sort of 56 accounting concepts. The high level of agreement on the Q‐sort was evidence for a “community of preference.” Lists of the essential and least important concepts were developed from this community of preference. The Q‐sort appears to be an efficient and effective “method” for determining what emphasis instructors should place on course content items. 相似文献

AbstractThe present investigation verified that strength is improved by a training programme consisting of repetitions of maximal isometric voluntary co-contractions without increasing co-activations during contractions against external resistances. Ten participants performed 12 training sessions (four sets of 6 × 4 second maximal isometric co-contraction of the elbow flexor and extensors, 3 days a week for 4 weeks). Surface electromyograms of triceps and biceps brachii were collected during maximal voluntary isometric elbow flexion and extension against a force transducer. Maximal voluntary isometric force increased significantly after training, by 13.8 ± 6.0% (extension) and 9.6 ± 9.5% (flexion), but the observed increases in EMG of agonist muscles during maximal voluntary contraction were not significant. No significant changes in the levels of co-activation of the elbow flexors and extensors were observed. No significant change was observed for all the parameters in a control group of ten participants. These results indicated that the strength improvements after co-contraction training occur without increases in co-activation level. 相似文献

Drawing on a teacher concerns framework, alongside notions of critical consciousness, this article examines the extent to which teacher candidates' (TCs') concerns are related in any way to the critical scholarship they have engaged with throughout their teacher education coursework. Utilizing teacher candidates' written dilemmas of practice during student teaching as the primary data source, the authors utilize consensual qualitative research for data analysis and share results within and across concern categories as related to notions of critical consciousness and dysconsciousness (King, 1991). Results indicate that TCs' posted self concerns lacked a critical inward journey; that TCs were more likely to be critically conscious regarding their own positionality in schools, yet overwhelmingly dysconscious when talking about students and families; and that large percentages of dysconscious task concerns seem related to TCs' lack of critically conscious posts about self. The authors suggest the importance of more focused mentorship and assignments aimed at asking questions designed to promote critically conscious ways of being in classrooms, and similarly suggest the importance of considering notions of critical consciousness in concerns-based studies moving forward. The authors end with a note of caution on the movement toward “core practices” in teacher preparation and instead suggest the importance of programming that focuses on uncovering and eradicating dysconsciousness among TCs working with historically marginalized youth. 相似文献
