Motivation and Self-regulation in Community College Transfer Students at a Four-year Online University     

Alexandra List  Denise Nadasen 《Community College Journal of Research & Practice》2013,37(12):842-866

ABSTRACT

Motivation and self-regulation were examined in a sample of community college transfer students enrolled in a 4-year, online university. The relation between motivation and self-regulation and students’ performance was examined, as was the association between these learner characteristics (i.e., motivation and self-regulation) and sociodemographic factors (e.g., marital status, employment status). Motivation was found to be significantly correlated with both semester and cumulative grade point average (GPA), while associations between self-regulation and performance were more limited. Further, motivation was found to be a significant predictor of semester GPA in a model controlling for sociodemographic factors and prior achievement. Motivation and self-regulation were also found to differ according to students’ sociodemographic status. For instance, transfer students with children under 18 were found to have significantly higher levels of motivation than nonparents. Those employed full-time had lower levels of self-regulation than did their nonemployed peers. Implications for further research on community college transfer students and online learning are discussed.  相似文献   

The angiogenetic effect of intramuscular administration of b-FGF and a-FGF on cardiac muscle: The influence of exercise on muscle angiogenesis     

Anna Efthimiadou  Byron Asimakopoulos  Nikos Nikolettos  Alexandra Giatromanolaki  Efthimios Sivridis  Theodoros S. Lialiaris 《Journal of sports sciences》2013,31(8):849-854

Abstract

Although angiogenetic therapy using recombinant growth factors holds much hope for the treatment of ischaemic diseases, there are still many unanswered questions, including the method of administration, the correct dose of these factors, and the duration of the therapeutic approach. Exercise has also been suggested to induce neovascularizaiton in muscles. We evaluated the angiogenetic effects of the intramuscular administration of basic-fibroblast growth factor (b-FGF) and acidic-fibroblast growth factor (a-FGF) in rat heart, compared with rats who exercised daily. In conclusion, both the intramuscular administration of b-FGF and exercise increased significantly angiogenesis in the heart in contrast to the intramuscular administration of a-FGF, which was ineffective.  相似文献   

The microcycle of inflammation and performance changes after a basketball match

Abstract

Basketball incorporates intense eccentric muscle activity that induces muscle microtrauma and an inflammatory response. This study investigated time-dependent inflammatory and performance responses during a weekly microcycle after a basketball match. Twenty elite-standard players underwent a trial that comprised a match followed by a 6-day simulated in-season microcycle. The trial was preceded by a control condition that did not have a match. Blood sampling and tests of maximal-intensity exercise performance and muscle damage occurred before each condition, immediately after the match and daily thereafter for 6 consecutive days. The match induced marked increases in heart rate, lactate, ammonia, glucose, non-esterified fatty acids and triglycerides. Performance deteriorated for 24–48 h after the match, whereas knee flexor and extensor soreness increased for 48 and 24 h post-match, respectively. Inflammatory (leukocytes, C-reactive protein, creatine kinase activity, adhesion molecules, cortisol, uric acid and cytokines) and oxidative stress (malondialdehyde, protein carbonyls, oxidised glutathione, antioxidant capacity, catalase and glutathione peroxidase) markers increased for ~24 h and subsided thereafter. Reduced glutathione declined for 24 h after exercise. These results suggest that a basketball match elicits moderate and relatively brief (~24–48 h) inflammatory responses, is associated with marked but short-lived performance deterioration, but is less stressful than other intermittent-type sports.  相似文献   

Gendered practices in the education of gifted girls and boys     

Barbara A. Kerr  M. Alexandra Vuyk  Chistopher Rea 《Psychology in the schools》2012,49(7):647-655

Gifted girls and gifted boys are more alike than they are different, although researchers remain fascinated with sex differences. Small differences between gifted boys and girls in achievements, interests, careers, and relationships can become exaggerated through gendered educational practices. Kindergarten “red‐shirting'' of boys and the denial of early admission to girls can cause gifted children to be out of step throughout their academic careers. When gifted children are not actively encouraged to participate in talent searches and after‐school and summer programs, whether because of overprotection of girls or the insistence on athletic activities at the expense of academic activities for boys, they lose the opportunity for challenge, friendships, and community. When boys are not supported in their interests in creative careers and girls are not supported in their interests in science, technology, engineering, and mathematics careers, they may enter occupations that will not offer them the sense of purpose and meaning they might have otherwise had. It is in the area of gender relations, however, that long‐term consequences of gendered practices are most apparent for gifted individuals because both gifted boys and girls need to plan for balancing family and career. © 2012 Wiley Periodicals, Inc.  相似文献

Identification of Effective Strategies to Promote Language in Deaf Children With Cochlear Implants     

Ivette Cruz  Alexandra L. Quittner  Craig Marker  Jean L. DesJardin  CDaCI Investigative Team 《Child development》2013,84(2):543-559

Parental involvement and communication are essential for language development in young children. However, hearing parents of deaf children face challenges in providing language input to their children. This study utilized the largest national sample of deaf children receiving cochlear implants, with the aim of identifying effective facilitative language techniques. Ninety‐three deaf children (≤ 2 years) were assessed at 6 implant centers prior to and for 3 years following implantation. All parent–child interactions were videotaped, transcribed, and coded at each assessment. Analyses using bivariate latent difference score modeling indicated that higher versus lower level strategies predicted growth in expressive language and word types predicted growth in receptive language over time. These effective, higher level strategies could be used in early intervention programs.  相似文献   

Stakeholder Identification of Barriers and Facilitators to Sexual Health Education for Female Survivors of Violence: A Mixed Methods Study     

Brooke E. E. Montgomery  S. Alexandra Marshall  Sharon E. Sanders  Martha M. Phillips  Michelle Cline  Max Snowden 《American journal of sexuality education》2018,13(1):18-39

There is a strong relationship between experiencing violence and participating in behaviors that increase the risk of contracting sexually transmitted infections. Sexual health education (SHE) tailored to the unique needs of female survivors of violence is needed. This paper presents findings from 40 surveys and 33 accompanying interviews with stakeholders representing 31 agencies in the violence advocacy community in Arkansas to investigate the feasibility, acceptability, and perceived need of a SHE program for female survivors of violence. Data also explore the role and preferences of community agencies in the design and implementation of such a program. Interviews with stakeholders revealed three themes: intervention concerns, content, and structure.  相似文献   

Religious education in Russia: a comparative and critical analysis     

Alexandra Blinkova 《British Journal of Religious Education》2018,40(2):194-206

RE in Russia has been recently introduced as a compulsory regular school subject during the last year of elementary school. The present study offers a critical analysis of the current practice of Russian RE by comparing it with RE in Sweden, Denmark and Britain. This analysis shows that Russian RE is ambivalent. Although it is based on a non-confessional religious studies approach, Russian RE also serves the interests of the Russian Orthodox Church, which aims to educate students into Orthodox Christianity, as well as the interests of the Russian state itself, which turns RE in a kind of citizenship education focusing on the patriotic upbringing of students.  相似文献
