Abstract

This study examined whether gender and/or training were related to the exercise-induced changes in plasma concentrations of growth hormone (GH), prolactin (PRL), triiodothyronine (T3), and thyroxine (T4). Twenty subjects (male and female 10-km runners; untrained males and females) ran on a treadmill for 30 win at 80% of previously determined maximum heart rate. Blood samples were taken through an indwelling catheter from an antecubital vein at ?30, 0, +15, +30 min of the test and 30 min of recovery. Reded temperature rose significantly (p < .01) at +15 and +30 min with concomitant rise in GH concentration, but PRL, T3, and T4 were not affected by the exercise. We concluded that a 30-min run at 80% of maximum heart rate is associated with higher concentrations of GH but not of PRL, T3, and T4 Neither training state nor gender affected the aforementioned results.  相似文献

After a major redesign project in 2002, Mayo Clinic Libraries' heavily used intranet portal remained largely static. Library staff were unable to make substantive design changes or introduce tools that would make the content more dynamic. CampusGuides offered a practical, user-friendly, web-based solution to add dynamic content to the library site. A task force was formed both to establish design and style guidelines that would integrate with the library site and to plan the conversion of content to CampusGuides. Converting intranet site content to CampusGuides gave the task force the opportunity to examine, re-imagine, and revitalize site content.  相似文献

ABSTRACT

This study investigates whether differences in learning styles exist between students in online and face-to-face (FTF) sections of political science courses taught by three instructors. Some studies suggest that student preferences regarding online or FTF formats are influenced by their preferred modes of learning. Independent learners, for example, may prefer online courses since they provide individualistic opportunities to study outside of the traditional classroom. This study uses original survey data to assign students one of six learning styles in order to assess whether independent learners are more common in online courses. Our analysis finds no significant differences in independent learners when comparing the two formats. This finding runs counter to studies that argue that independent learners tend to prefer online courses. In fact, the only learning style where we observe a meaningful difference among online and FTF formats is among dependent learners. Contrary to expectation, students enrolled in online versions demonstrated a greater tendency toward dependent modes of learning. Further survey responses suggest that student lifestyle drove course format selection rather than learning style. These findings have important implications for universities that increasingly turn to online courses to address decreasing enrollments and attempt to remedy the high attrition rates associated with those courses.  相似文献

The concept of leader-member exchange (LMX) is predicated on the notion that leaders have differing quality relationships with each subordinate, leading to the formation of an ingroup and an outgroup. This suggests that for a sophisticated understanding of the impact of LMX relationships on individuals’ sentiments and behaviors, followers’ perceptions of the collective set of workgroup LMX relationships may be as important as their individual LMX relationships. This research examines employee perceptions of LMX across 67 work units, and investigates how these perceptions relate to coworker exchange (CWX) relationships and organizational citizenship behavior (OCB). Results indicate that CWX is strongly, positively related to the LMX of the participant and their colleagues. A significant, positive relationship between measures of CWX and OCBs directed toward the work unit, but not the organization, was also observed.  相似文献

This article examines the question: Do lexical, syntactic, fluency, and discourse measures of oral language collected under narrative conditions predict reading achievement both within and across languages for bilingual children? More than 1,500 Spanish–English bilingual children attending kindergarten–third grade participated. Oral narratives were collected in each language along with measures of Passage Comprehension and Word Reading Efficiency. Results indicate that measures of oral language in Spanish predict reading scores in Spanish and that measures of oral language skill in English predict reading scores in English. Cross‐language comparisons revealed that English oral language measures predicted Spanish reading scores and Spanish oral language measures predicted English reading scores beyond the variance accounted for by grade. Results indicate that Spanish and English oral language skills contribute to reading within and across languages.  相似文献

Experts play important roles in supporting public deliberation. These roles include developing and vetting background materials, participating in question-and-answer sessions with citizens, and giving pubic presentations. Rarely, though, are experts asked to be on hand during deliberative forums, whereby they have the opportunity to interact with deliberating groups. The inclusion of experts during forums presents a tension because, although they can elevate the quality of the conversation by correcting factual errors, they can also, perhaps unknowingly, crowd out and silence citizen, or “nonexpert,” participation. Careful consideration of communication design can help public deliberation practitioners manage this tension so that experts, when involved in forums, enhance rather than undermine the deliberative process. Taking communication as design, we analyze the interaction of an invited expert at a water scarcity forum in Northern Colorado who derailed discussion and hindered dialogue by “going rogue.” We then turn to stasis theory to conceptualize the effective inclusion of technical experts in public deliberations. Through forum design and training practices, we propose that experts can help resolve issues of conjecture and definition in a manner that frees deliberating groups to discuss substantive and subjective issues of quality and policy.  相似文献

In this experimental study, we examined the effects of a multicomponent reading comprehension intervention in sixth- to eighth-grade English language arts classes with a focus on factors to enhance treatment implementation. We tested the contribution of a theoretically derived fidelity framework that included adherence, quality, dosage, program differentiation, and student responsiveness. The study was conducted in three schools, involving 14 teachers and 859 students. English language arts classes were randomly assigned to the Comprehension Circuit Training intervention (n?=?30) or typical practice comparison (n?=?31) conditions, and all teachers taught in both conditions. Findings indicated that there was no reliable difference between the intervention and typical practice groups on standardized or researcher-developed proximal measures. To investigate the relationship between fidelity and student outcomes, we conducted a confirmatory factor analysis (CFA) to determine the relation of the indicators to a latent fidelity factor. Results of the CFA revealed a single fidelity factor composed of the adherence, quality, dosage, student responsiveness, and program differentiation variables. The fidelity factor was statistically significantly related to outcomes on a standardized comprehension measure (γ?=?.86, p?γ?=?.52, p?相似文献
