El autor narra aquí, con anécdotas, ejemplos y reflexiones tan concretas como cargadas conceptualmente, su aventura cotidiana como profesor de Lengua a la búsqueda de la verdad sobre el modelo y enfoque teórico-pedagógico que se debe aplicar entre los actualmente contendientes: el enfoque de la gramática formalista o el de los gramáticos «tradicionales». El resultado es quizá sorprendente y tiene implicaciones serias: el modelo tradicional ofrece mayor productividad, lo que el autor atribuye a que presta mayor atención—a su manera—al contexto. Esta presencia del contexto en los modelos tradicionales se presenta como el posible puente para conectar las actuales gramáticas pragmáticas y textuales—más prometedoras para el autor que las formales—con los modelos del lenguaje de la didáctica tradicional.  相似文献

This research uses a conceptual model to examine the influence of a change in accreditation standards on a representative national sample of 203 engineering programs at 40 institutions. Based on data collected from more than 140 program chairs, 1,200 faculty, 4,300 graduates of 2004, and 5,400 graduates of 1994, the study investigates the differential impact of the change in accreditation standards on programs reviewed in different years during the period of transition. Despite significant variation across most of the measures and groups in 1994 (before the introduction of the new accreditation criteria), the 2004 evidence demonstrates a surprisingly uniform level of student experiences and outcomes. These findings suggest that engineering accreditation is beginning to accomplish its quality assurance goals. This is a revised version of a research paper presented at the meeting of the Association for Institutional Research, May 17, 2006, Chicago, IL.  相似文献

The purpose of the current study was to examine the effect of 6 weeks of whole body vibration training (WBVT) on body composition, muscle activity of the gastrocnemius and vastus lateralis, gastrocnemius muscle architecture (static and dynamic) and ground reaction forces (performance jump) during the take-off phase of a countermovement jump in young healthy adult males. A total of 33 men (23.31 ± 5.62 years) were randomly assigned to a whole body vibration group (experimental group, EGWBVT: n = 17; 22.11 ± 4.97 years) or a control group (CG: n = 16; 24.5 ± 6.27 years). The total duration of the intervention phase (WBVT) was 6 weeks with a frequency of 3 sessions per week. Statistically significant differences were observed (P ≤ 0.05) between pre- and post-test in the power peak (Δ 1.91 W · kg?1; P = 0.001), take-off velocity (0.1 cm · s?1; P = 0.002) and jump height (Δ 0.4 cm; P = 0.002) for EGWBVT. There were no statistically significant differences in any of the body composition and muscle architecture variables. Moreover, no significant differences were found between EGWBVT and CG nor changes in muscle activity during take-off phase of the gastrocnemius and vastus lateralis pre- versus post-training. This study suggests that a 6-week WBVT programme with increasing intensity improves jump performance but does not alter muscle activity nor muscle architecture in healthy young men.  相似文献

Perhaps two-thirds of the gains students make in knowledge and cognitive skill development occur in the first 2 years of college (Pascarella, E. T., and Terenzini, P. T. (2005). How college affects students Vol. 2. A third decade of research. San Francisco: Jossey-Bass). A significant proportion of the students entering America’s colleges and universities, however, never make it to their second year at the institution where they began. This study, part of a national effort to transform how colleges and universities think about, package, and present their first year of college, is based on data from nearly 6,700 students and 5,000 faculty members on 30 campuses nationwide. The study identifies the individual, organizational, environmental, programmatic, and policy factors that individually and collectively shape students’ development of academic competence in their first year of college. *Paper presented at the meeting of the Association for Institutional Research, June 6, 2005 San Diego, CA. This study was supported by grants from the Atlantic Philanthropies and the Lumina Foundation for Education to the Policy Center for the First Year of College, Brevard, NC.

BackgroundTo finish an endurance race, athletes perform a vigorous effort that induces the release of cardiac damage markers. There are several factors that can affect the total number of these markers, so the aim of this review was to analyze the effect of endurance running races on cardiac damage markers and to identify the factors that modify the levels of segregation of these cardiac damage markers.MethodsA systematic search of PubMed, Web of Science, and the Cochrane Library databases was performed. This analysis included studies where the acute effects of running races on cardiac damage markers (troponin I and troponin T) were analyzed, assessing the levels of these markers before and after the races.ResultsThe effects of running races on troponin I (mean difference = 0.0381 ng/mL) and troponin T (mean difference = 0.0256 ng/mL) levels were significant. The ages (R2 = 14.4%, p = 0.033) and body mass indexes (R2 = 14.5%, p = 0.045) of the athletes had a significant interaction with troponin I. In addition, gender, mean speed, time to finish the race, and type of race can affect the level of cardiac damage markers.ConclusionEndurance running races induce the release of cardiac-damage markers that remain elevated for at least 24 h after the races. In addition, young male athletes with high body mass indexes who perform races combining long duration and moderate intensity (i.e., marathons) release the highest levels of cardiac damage markers. Physicians should take into consideration these results in the diagnosis and treatment of patients admitted to the hospital days after finishing endurance running races.  相似文献

The Meyerhoff Scholarship Program (MSP) is widely recognized for its comprehensive approach of integrating students into the science community. The supports provided by the program aim to develop students, primarily Blacks, into scientists by offering them academic, social, and professional opportunities to achieve their academic and career goals. The current study allowed for a rich understanding of the perceptions of current Meyerhoff students and Meyerhoff alumni about how the program works. Three groups of MSP students were included in the study: (1) new Meyerhoff students participating in Summer Bridge (n = 45), (2) currently enrolled Meyerhoff students (n = 92), and (3) graduates of the MSP who were currently enrolled in STEM graduate studies or had completed an advanced STEM degree (n = 19). Students described the importance of several key aspects of the MSP: financial support, the Summer Bridge Program, formation of Meyerhoff identity, belonging to the Meyerhoff family, and developing networks—all of which serve to integrate students both academically and socially.  相似文献

This article explores the theory of action underlying New York University's (NYU's) Partnership Schools Program—explaining in the process what a theory of action is, and how it can be constructed for other innovations in other contexts. NYU's Partnership Program involves 23 schools, K-12, spanning several of New York City's most economically disadvantaged neighborhoods. It operates on the basis of what the authors call “mutual self-interest” and exploits what they call “complementarity.” The authors illuminate the program's original as well as its evolving intentions, and the environmental conditions necessary to enact them and to sustain the program over a decade. They also describe the program's core design elements, with a view to how these may be replicated elsewhere. Finally, they look closely at the Partnership's theory of action in action, employing action research data to portray a meeting where professors and teachers discuss the teacher education residency experiment they have collaboratively launched.  相似文献

This paper aims to analyze the companies’ view about the financial valuation of intangibles relevance and its influence on corporate performance. Based on the theory of resources, the role of intangibles in business competitiveness is justified. The traditional factors of production have become secondary, while the success is primarily based on the development and utilization of intangible resources. One of the main problems in managing the intangibles appears to be that, there is a general lack of information about them. Therefore, financial valuation of intangibles will result in significant benefits to the organization that will help determine business strategy, process design as well providing competitive advantage. It follows the hypothesis of this work, the greater known about their intangibles and the greater sensitivity to the financial valuation of them, the better performance. To achieve this objective, a field study is done, doing telephone calls to Basque Country companies’ financial managers.  相似文献
