This article outlines evidence-based methods for cultural heritage institutions to look for news and mentions about their collections and services online. Google Alerts were created for repository names, websites, and finding aid websites for 66 institutions randomly selected from the Archive Grid database. Results were analyzed to determine Google Alerts' accuracy, what types of institutions would benefit most from using Google Alerts, what the content of the sources found by the alerts was, what types of publications returned the most results, and if Google Alerts could also identify image reuse. While Google Alerts' accuracy for returning usable results for analysis was not very high, the structure of alert e-mails makes discarding irrelevant results simple and quick. Mid- to large-sized museums and institutions staging frequent exhibits and events, as well as those with active collections, return the largest number of alerts. News publications and social media publish the most content related to cultural heritage institutions. Though the sample set was small, Google Alerts also was able to identify image reuse.  相似文献

ABSTRACT

The systematic review and meta-analysis evaluated the effect of aerobic, resistance and combined exercise on RMR (kCal·day-1) and performed a methodological assessment of indirect calorimetry protocols within the included studies. Subgroup analyses included energy/diet restriction and body composition changes. Randomized control trials (RCTs), quasi – RCTs and cohort trials featuring a physical activity intervention of any form and duration excluding single exercise bouts were included. Participant exclusions included medical conditions impacting upon RMR, the elderly (≥65 years of age) or pregnant, lactating or post-menopausal women. The review was registered in the International Prospective Register of Systematic Reviews (CRD 42,017,058,503). 1669 articles were identified; 22 were included in the qualitative analysis and 18 were meta-analysed. Exercise interventions (aerobic and resistance exercise combined) did not increase resting metabolic rate (mean difference (MD): 74.6 kCal·day-1[95% CI: ?13.01, 161.33], P = 0.10). While there was no effect of aerobic exercise on RMR (MD: 81.65 kCal·day-1[95% CI: ?57.81, 221.10], P = 0.25), resistance exercise increased RMR compared to controls (MD: 96.17 kCal·day-1[95% CI: 45.17, 147.16], P = 0.0002). This systematic review effectively synthesises the effect of exercise interventions on RMR in comparison to controls; despite heterogenous methodologies and high risk of bias within included studies.  相似文献

Physical profile data from elite, sub-elite, regional, under 21s (U21), under 19s (U19) and under 17s (U17) (n = 845) players from a state netball association in Australia were analysed. Within season changes were examined for the elite and sub-elite players. Longitudinal changes were examined for the elite across four consecutive netball seasons.

Elite were significantly older (24.3 ± 3.4years), taller (182.4 ± 7.2cm) and heavier (73.42 ± 6.95kg) than other playing levels (p < 0.001, ES 0.49–3.26) and had higher vertical jump (VJ) data compared to all groups (p < 0.001, ES 0.47–0.93). U17’s were significantly faster than elite, sub-elite and U19 players over 5m (p < 0.05, ES 0.36–0.58) while elite were faster over 20m compared to all groups (p < 0.01, ES 0.45–0.72). Elite achieved a greater distance (1350.8m; p < 0.05, ES 0.32–0.50) in the Yo-YoIRT1 compared to the sub-elite, regional, U19 and U17. VJ height significantly increased from the 2014 (51.6 ± 4.8cm) to the 2017 season (59.6 ± 6.3cm) for the elite players (p < 0.01, ES 1.18). Yo-YoIRT1 test scores increased significantly between the pre-season and in-season phases (p < 0.05, ES 0.17).  相似文献

The authors examined supervisor cultural humility as a predictor of supervisee intentional nondisclosure. Using multiple regression in a sample of 101 post-master's counselors, the authors found that 20% of supervisees' intentional nondisclosure was explained by their perceptions of their supervisors' level of cultural humility.  相似文献

ABSTRACT

This study explores the idea of creating a knowledge base from shared online accounts to use in training librarians who perform distance reference services. Through a survey, follow-up interviews and a case study, the investigators explored current and potential use of shared online accounts as training tools. This study revealed that the participants viewed the concept positively, but many encountered barriers to effectively employing a local knowledge base as a training tool.  相似文献

This birth story illustrates one woman's view of the importance of the type of birthing care she received and the involvement of her existing child in a second birth. The value of the mother's vision and her ability to participate in fully informed choices are emphasized.  相似文献

Research Findings: We examined whether affective social competence, or the ability to effectively send and receive emotional signals and to manage one's own emotional experience, contributes to preschool children's peer relations. Forty-two previously unacquainted preschoolers were observed while participating in a week-long playschool. Greater nonstereotypical emotion knowledge was related to girls' popularity and boys' likelihood of having a reciprocal friendship. Girls with greater skill at sending emotional communications and managing emotions were more likely to have a reciprocal friendship. Boys who were better at managing emotions compared to others in their group were less popular. The role of social context in the influence of affective social competence on children's peer relations is discussed. Practice or Policy: Results have implications for early childhood educators' promotion of children's socioemotional skills.  相似文献

Predominantly White institutions have not been as effective as historically Black institutions in retaining and conferring degrees upon African American college students. This review seeks to embed the psychological aspects of the retention process proposed by Bean and Eaton [A psychological model of college student retention. In J. M. Braxton (Ed.), Reworking the student departure puzzle (pp. 48–61). Nashville, TN: Vanderbilt University Press, 2000] in a culturally-sensitive framework and consider how African American students attending PWIs may experience the processes in retention. We first give a brief overview of Bean and Eaton’s [A psychological model of college student retention. In J. M. Braxton (Ed.), Reworking the student departure puzzle (pp. 48–61). Nashville, TN: Vanderbilt University Press, 2000] model of retention, then we propose and discuss revisions to Bean and Eaton’s model that we believe would make the model more applicable to African American students attending predominantly White institutions. Specifically, we address students’ attitudes towards their institution, academic self-efficacy, motivation, achievement goals, attributions, and ethnic and bicultural identity development. The discussion concludes with implications and directions for future study.  相似文献
