The objectives of this study were to determine the percentage of students who felt they were weak in an academic skill and who took a college assistance program designed to correct that deficiency and to identify the reasons given by students weak in an academic skill for not using a college support service from which they could benefit. Analyses of survey data obtained from 268 instructors and 6,428 of their students enrolled in a cross section of courses in a large multicampus urban community college district showed the following: (1) of those students who did not feel confident in a skill, less than 30% took advantage of a support program designed to assist them in that skill; (2) more than 40% of the faculty felt that the primary reason students did not take advantage of a needed support service was that they were not willing to devote the extra time or effort required to avail themselves of the service; and (3) the main reasons most academically underprepared students gave for not using a support service were that they did not feel a need for the service or had no time for the service. Implications of these findings for educational policy are discussed. 相似文献

The purpose of this study was to determine the effects of short-term normoxic and hypoxic exercise on plasma endothelin-1 and nitric oxide levels, and the relationship of arterial compliance and pulmonary artery pressure to endothelin-1. Seven endurance-trained males completed two incremental and two steady-state exercise tests performed at ventilatory threshold in normoxia and hypoxia (fraction of inspired oxygen = 0.14). Plasma endothelin-1was measured throughout steady-state tests. Arterial compliance using applanation tonometry, plasma nitric oxide and pulmonary artery pressure using Doppler echocardiography were measured before and after exercise. Small arterial compliance and pulmonary artery pressure significantly increased following exercise. There were no main effects of condition or time for plasma endothelin-1and nitric oxide levels. There were no significant relationships between plasma endothelin-1 and arterial compliance or pulmonary artery pressure. In conclusion, mechanisms other than the endothelial system may play a role in the exercise-induced changes in small artery compliance in this study population. Moderate hypoxia and a 30-minute steady-state exercise have limited effects on plasma endothelin-1 in endurance-trained males. 相似文献

The purpose of this study was to explore the relationships among cognitive processing, phonological processing and basic reading skill performance. Cognitive theorists propose that Planning, Attention, Simultaneous and Successive (PASS) processes are related to various phonological skills. A sample of 62 Primary Grade children referred for reading problems were administered measures of cognitive processes (Cognitive Assessment System), phonological processes (Comprehensive Test of Phonological Processing) and basic reading achievement (Woodcock‐Johnson Tests of Academic Achievement‐III). Findings indicated that some cognitive processes were significantly related to phonological processes as well as basic reading skills. The strongest relationships were found between phonological memory and successive processes and between phonological awareness and basic reading performance. 相似文献

The brief note aims to illustrate how historical context has contributed to my writing on modern sports law and principally through two pieces of work – the first relating to the historical, sui generis origins of the legality of combat or fighting sports, which continues to stretch the boundaries of core principles of criminal law, such as reasonable consent to bodily harm, to their utmost; and second, and more generally, the ‘historicalegal’ influences on the development of modern sport in mid-nineteenth-century Britain. Before that is done, it is best to give some account of research methodologies in legal scholarship and principally as they apply to legal history. 相似文献

The need for science communication programs is matched with the need for program evaluation. This case study is an evaluation of the “Decoding Science” program (DSP) [Rodgers et al. (2018). Science Communication, 40(1), 3–32], a science communication training program, and examines key experiential-learning themes [Kolb, D. A. (1984). Experiential learning: Experience as the source of learning and development. Englewood Cliffs, NJ: Prentice-Hall]. Specifically, we discuss the program's emphasis on learning that science communication is a process that (a) is continual, (b) involves conflict resolution, (c) requires adaptation to the world, (d) requires environmental interaction, and leads to (e) knowledge creation. Additionally, we discuss our analysis of student feedback. Results suggest that the DSP successfully utilizes experiential learning to facilitate the learning of science communication techniques and that future evaluations can lead to the development and improvement of science communication training programs. 相似文献

Whilst previous research has highlighted significant relationships between golfers’ clubhead velocity (CHV) and their vertical jump height and maximum strength, these field-based protocols were unable to measure the actual vertical ground reaction force (vGRF) variables that may correlate to performance. The aim of this study was to investigate relationships between isometric mid-thigh pull (IMTP), countermovement jump (CMJ), squat jump (SJ) and drop jump (DJ) vGRF variables and CHV in highly skilled golfers. Twenty-seven male category 1 golfers performed IMTP, CMJ, SJ and DJ on a dual force platform. The vertical jumps were used to measure positive impulse during different stretch-shortening cycle velocities, with the IMTP assessing peak force (PF) and rate of force development (RFD). Clubhead velocity was measured using a TrackMan launch monitor at a golf driving range. Pearsons correlation coefficient analyses revealed significant relationships between peak CHV and CMJ positive impulse (r = 0.788, p < 0.001), SJ positive impulse (r = 0.692; p < 0.001), DJ positive impulse (r = 0.561, p < 0.01), PF (r = 0.482, p < 0.01), RFD from 0–150 ms (r = 0.343, p < 0.05) and RFD from 0–200 ms (r = 0.398, p < 0.05). The findings from this investigation indicate strong relationships between vertical ground reaction force variables and clubhead velocity. 相似文献
