Three hundred and seventy-nine participants were tested in the West Indies and in Canada, with the Rotter Locus of Control Scale and the Wolfgang Interpersonal Distance Test. The results indicated that West Indian adolescent students were more internally controlled than their Canadian counterparts. Also, overall, West Indian students showed more approach behavior toward significant interpersonal figures than Canadian students. In addition, no correlation was apparent between locus of control and social distance, suggesting that they are separate constructs. Implications of the findings for social adjustment of West Indian immigrants in Canada are discussed. 相似文献

Five junior scholars, representing two departments and four program areas in the College of Education at the University of North Texas, committed themselves to a long-term, systematic, research-based learning program in order to further their knowledge and skills as qualitative researchers. In this essay, this community of learners describes their collaborative efforts to develop more effective skills in one method of qualitative research, in-depth, oral history interviewing. Through their cross-discipline, research-based, faculty development model, the authors offer helpful direction to other higher education faculty who seek to improve their ability to conduct and also to guide students in qualitative investigations. 相似文献

Zusammenfassung. Die Bereitstellung eines pr?zisen, effizienten und m?glichst vollst?ndigen Zugriffs auf aktuelle Informationen im Internet
ist eine grundlegende Voraussetzung für die Weiterentwicklung des elektronischen Handels. Dieser Beitrag zeigt, wie themenspezifische
Suchwerkzeuge mit Hilfe mobiler Programme eine solche Bereitstellung leisten k?nnen. Der vorgestellte Ansatz wird durch messdaten-basierte
Simulationen sowie anhand einer Fallstudie evaluiert.

The national media converged on Baltimore, Charleston, and Ferguson, Missouri, in 2014 and 2015 to cover protests in response to police violence toward African American males. Although national and local media covered the events and the aftermath, alternative media sought to provide additional viewpoints and spur readers to respond. This study analyzed the practices, content, and public discourse connected to alternative weekly newspapers in Baltimore, Charleston, and St. Louis. The study examined whether the publications reflected ideal roles of alternative media, including representing different viewpoints, using non-traditional methods of content, and providing a space for the public to challenge systems of power and oppression. The authors also studied the online forums associated with all three publications, including each organization’s website and Facebook page, as potential spaces for alternative publics to emerge around a shared interest in collective action. The publications showed some characteristics of the ideal form of alternative media, but most lacked the diverse voices and critical calls to action needed to represent the normative standard. The discourse the news organizations spurred also fell short of the ideal. The forums lacked rational and critical engagement, and commenters largely failed to promote sincere attempts to engage in community conversation. 相似文献

Elevation gain (EG) is a significant contributor to the total workload in many endurance sports. Hence, the aim of this study was to evaluate the accuracy of elevation recording as assessed by popular sport watches. Eighteen participants walked and ran at different speeds in various weather conditions in two terrain types: on a hilly 2490 m course with a total EG of 90 m and on a flat 1200 m outdoor track with 0 m EG. In total, 180 recordings from each sport watch were analyzed and compared according to two processing types: filtered and unfiltered EG data. Compared to the reference values, regarding default settings, on hilly terrain, EG was underestimated by ?3.3 to ?9.8 %, and on flat terrain, EG was overestimated by 0.0–4.8 m per 1200 m. These errors could be reduced to ?3.3 to +0.4 %, when filtering conditions were adjusted according to the terrain. Gait speed (ranging from 1.47 to 4.89 m s?1) or fluctuations in weather conditions between- or within-trials did not influence EG accuracy. A straightforward comparison between manufacturers is hampered as the filter conditions set by default differ. In conclusion, all devices measure EG adequately; however, the displayed default feedback on EG data is not always the most accurate measurement. Consequently, accuracy in elevation recordings could be increased if users appropriately post-process EG data. 相似文献
