Effects of glucose–fructose versus glucose ingestion on stride characteristics during prolonged treadmill running

Scarce research has examined the effects of carbohydrate composition on running stride characteristics. On two occasions, 14 males and 6 females completed a 120-min sub-maximal run followed by a 4-mile time trial. Participants consumed glucose (GLU) or glucose–fructose (GLU–FRU) beverages supplying 1.3 g/min carbohydrate. Substrate use, psychological affect [Feeling Scale (FS)], and stride characteristics (stride frequency, stride length, and contact time) were assessed. Effects were expressed as Cohen’s d (90% confidence limits [90% CL]). CLs for stride frequency differences at 53 min (90% CL = 0.04–0.21) and 113 min (90% CL = 0.02–0.24) did not cover 0, indicating a positive effect of GLU–FRU. However, effect sizes were small (d = 0.13) and likely-to-very-likely trivial. Energy expenditure differences at sub-maximal end were very likely trivial (d = 0.08; 90% CL = 0.00–0.17), while FS ratings were possibly higher for GLU–FRU at 50 (d = 0.19; 90% CL = ?0.10–0.48) and 110 min (d = 0.16; 90% CL = ?0.13–0.45). During the time trial, stride length was possibly higher with GLU–FRU (d = 0.13; 90% CL = ?0.08–0.33). Glucose–fructose co-ingestion has no significant effect on stride characteristics during constant-velocity running but may result in slightly higher stride length during self-paced running.     

Understanding the consequences of victory amongst sport spectators: The mediating role of BIRGing

Prior work on the relationships between team identification and spectators’ reactions to one's team victory has largely neglected the potential effects of mediating variables. In this research, we proposed that the process of Basking in Reflected Glory [BIRGing – the tendency to reduce the distance between oneself and one's team; Cialdini, R. B., Bordon, R. J., Thorne, A., Walker, M. R., Freeman, S., &; Sloan, L. R. (1976). Basking in reflected glory: Three (football) field studies. Journal of Personality and Social Psychology, 34, 366–375] would lead spectators to almost take ownership of victories and share its benefits, thereby impacting their sense of national belonging in a positive manner. To this end, participants (N?=?73) were asked to watch an edited video clip showing a victory of the French national rugby team playing against South Africa. As expected, results revealed that BIRGing mediated the relationship between team identification and one's sense of national belonging. In closing, a number of implications are discussed along with future research avenues pertaining to the sport spectatorship literature.     

Operationalizing and validating disciplinary literacy in secondary education

The goal of this study was to define the construct and establish the validity of disciplinary literacy, which has recently gained attention from the implementation of the Common Core State Standards (National Governors Association Center for Best Practices & Council of Chief State School Officers in Common Core State Standards for English language arts & literacy in history/social studies, science, and technical subjects [PDF]. Authors, Washington, DC, 2010). After defining disciplinary literacy in the four core disciplines of English language arts, science, history and social studies, and mathematics, scales were developed and administered to a snowball sample of professionals nationwide, with 857 respondents. The data showed evidence of disciplinary literacy as a multidimensional construct with three related factors: source literacy, analytic literacy, and expressive literacy. Based on EFA and CFA results, we can conclude that there are at least three types of literacy in operation among the four core disciplines. The three factors of literacy varied significantly by the four core disciplines of English/language arts (ELA), science, history and social studies, and mathematics, supporting the notion that each discipline uses literacy uniquely. This is the first study of its kind to attempt to define, quantify, and validate the construct of disciplinary literacy.     

开放在线课程教法的适应性变革:从OCW到MOOC

文章旨在通过对OCW和MOOC所采用的教学方式的对比,探索开放在线课程在由"重资源"向"重服务"变革的过程中,其教学方法所发生的适应性变化。文章通过四个常用的开放在线课程搜索引擎,随机抽样出51门OCW课程和51门MOOC课程作为研究样本,并从课程说明中获取课程周数、建议学时、学习方式、教学手段等信息。结果表明:与OCW相比,MOOC建议以较短的周数、每周投入较多的时间来完成课程,以提高课程完成率;少量课程采用了基于项目、基于研究和基于团队的学习方式,但MOOC环境下的在线协作学习仍存在难度;在线论坛和讲座视频是MOOC中使用较多、发展较成熟的教学手段;社会媒体和位置地图等则是OCW中未出现而在MOOC中发展形成的。最后,文章根据研究结果提出了相应的教学建议。     

Against the current: A grounded theory study on the estrangement experiences of a select group of Filipino gay older persons

According to Healthy People (2011), in order to understand the health concerns of the Lesbian, Gay, Bisexual, and Transgender (LGBT), the oppression and discrimination that they have faced must be scrutinized. Among the many issues they face, their estrangement experiences are one of the most understudied. However, little is known about how it is experienced by the gay elderly population, hence, this investigation. This grounded theory purports to describe the process by which estrangement is experienced among the Filipino gay older adults. Strauss and Corbin’s Grounded Theory (1990) design was utilized. A total of 10 gay older persons were purposively chosen to participate in semi-structured interviews. Field texts were subjected to thematic analysis involving open, axial, and selective coding. The study generated The Sailing Model of Estrangement. Remarkably, three phases relative to estrangement emerged, namely: sequestering, striving, and surviving. Primarily, the sequestering phase involves the gay persons’ need to express self, search for acceptance, and its subsequent reactions. The striving phase typifies the struggle in dealing with estrangement leading to either feelings of depression, remorse and shame or positivity, hopefulness, and motivation. Finally, in the surviving phase, gay persons may either feel contented and fulfilled or sad, lonely, and remorseful as they acquiesce aging with estrangement. Findings of the study offer an understanding of how Filipino gay older adults employ coping strategies in response to estrangement.
