The Effects of a Preengineering Project-based Learning Curriculum on Self-efficacy Among Community College Students     

Soko S. Starobin  Yu “April” Chen  Aurelia Kollasch  Tushi Baul  Frankie Santos Laanan 《Community College Journal of Research & Practice》2014,38(2-3):131-143

Using statewide survey study data collected from more than 5,000 community college students, this study examined the impact of a preengineering curriculum on students' self-efficacy level after they entered rural community colleges. Project Lead The Way (PLTW), is a project-based learning curriculum for middle and high school students that strives to create a path to college and career success in STEM-related fields. In this article, the authors focused on comparing the probability of rating high self-efficacy among 86 community college students who participated in PLTW with students with no PLTW experience. The findings indicated that PLTW students have significantly lower probability of rating high self-efficacy compared to their non-PLTW counterparts. It might be that PLTW students rated their self-efficacy by comparing with a group of their close peers, who might be a group of academically high-ability students. This study provides implications for the unique, perhaps unintentional, peer effects of the project-based learning curriculum on the self-rating of students' self-efficacy. The findings highlighted the secondary-postsecondary nexus on STEM education, especially the importance of secondary programs that could positively influence the STEM educational pathways for community college students.  相似文献   

前列腺癌:亟待肿瘤标志物和治疗新靶点(英文)     

Juliana FELGUEIRAS  Joana Vieira SILVA  Margarida FARDILHA 《Journal of Zhejiang University. Science. B》2014,(1)

研究目的:这篇综述系统地阐述了前列腺癌的发生、发展、相关分子信号通路以及分子标志物用于前列腺癌的临床诊断和前列腺癌诊治所面临的挑战。重要结论:许多分子信号通路通过影响细胞生长、凋亡、血管生成等病理生理过程而参与了前列腺癌的起始、发生和发展。这些研究基础有助于寻找前列腺癌的肿瘤标志物和改进前列腺癌的治疗。虽然去势治疗是早期前列腺癌治疗的金标准,但是晚期的激素抵抗型前列腺癌(CRPC)的治疗仍面临着巨大的挑战。所幸的是,目前研究发现可以通过切断特异的蛋白-蛋白相互作用或者通过调节某些影响肿瘤生长和转移的关键分子来治疗前列腺癌,能减少传统治疗所带来的副作用;相关临床研究已开始实施。这些研究进展给前列腺癌的诊治带来了新的曙光。  相似文献   

Anthropometric profiles of elite older triathletes in the Ironman Brazil compared with those of young Portuguese triathletes and older Brazilians     

Silva DA  Benedetti TR  Ferrari EP  Meurer ST  Antes DL  Silva AM  Santos DA  Matias CN  Sardinha LB  Vieira F  Petroski EL 《Journal of sports sciences》2012,30(5):479-484

The objective of this study was to describe the anthropometric profiles of elite older triathletes participating in the 2009 Ironman Brazil and to compare their somatotype, anthropometric and body composition characteristics with those of elite young triathletes and older non-athletes. The sample consisted of 64 males, divided into three groups: (1) older triathletes (n = 17), (2) young triathletes (n = 24), and (3) older non-athletes (n = 23). Somatotype was analysed according to the Carter and Heath ( 1990 ) method. Body mass index, sum of four skinfolds, percentage body fat, body fat mass, and fat-free mass were also estimated. Older non-athletes had higher endomorphy, sum of four skinfolds, fat percentage, and body fat mass than the athletes. Older athletes who participated in the Ironman and elite young triathletes had higher fat-free mass than older non-athletes. Older triathletes and older non-athletes were considered mainly endomorphic mesomorphs and young triathletes mainly ectomorphic mesomorphs. The findings that characterize the anthropometric profile of athletes in this sports modality could be used as a reference.  相似文献   

A research impact indicator for institutions     

E.S. Vieira  J.A.N.F. Gomes 《Journal of Informetrics》2010,4(4):581-590

This paper introduces a new impact indicator for the research effort of a university, ⁿh₃. The number of documents or the number of citations obtained by an institution are used frequently in international ranking of institutions. However, these are very dependent on the size and this is inducing mergers with the apparent sole goal of improving the research ranking. The alternative is to use the ratio of the two measures, the mean citation rate, that is size independent but it has been shown to fluctuate along the time as a consequence of its dependence on a very small number of documents with an extremely good citation performance. In the last few years, the popularity of the Hirsch index as an indicator of the research performance of individual researchers led to its application to journals and institutions. However, the original aim of this h index of giving a mixed measure of the number of documents published and their impact as measured by the citations collected along the time is totally undesirable for institutions as the overall size may be considered irrelevant for the impact evaluation of research. Furthermore, the h index when applied to institutions tends to retain a very small number of documents making all other research production irrelevant for this indicator. The ⁿh₃ index proposed here is designed to measure solely the impact of research in a way that is independent of the size of the institution and is made relatively stable by making a 20-year estimate of the citations of the documents produced in a single year.  相似文献   

Desiring to Fit: Fostering the Success of Community College Transfer Students in STEM     

Dimitra Lynette Jackson  Frankie Santos Laanan 《Community College Journal of Research & Practice》2013,37(2):132-149

The United States is experiencing a dire need for individuals who possess training and expertise in areas of science, technology, engineering, and mathematics (STEM). With over half of the nation’s students entering university environments via community colleges coupled with a large portion of this population majoring in STEM areas, the successful transition and adjustment of community college transfer students is essential to the STEM workforce. This article uses an ex post facto survey research design to examine the socialization factors that impact the transition and adjustment experiences of community college transfer students in STEM disciplines. Two hierarchical regression models are employed to examine the factors that impact the academic and social adjustment of community college transfer students in STEM majors. This research was situated using an adaptation of Weidman’s (1987) Socialization Theoretical Framework. Implications, and recommendations for policy and practice will be provided based on the overall results of this study.  相似文献

The Role of Career and Technical Education in Iowa Community Colleges     

Frankie Santos Laanan  Jonathan I. Compton  Janice Nahra Friedel 《Community College Journal of Research & Practice》2013,37(4):293-310

ABSTRACT

This scholarly paper describes and analyzes the role of career and technical education (CTE) in Iowa community colleges. Iowa's community colleges are doing a good job of responding to the changing workforce needs of the state and providing smooth career pathways. However, changes in the population and economy of the state will call for further changes in CTE programs. The distinctive characteristics of CTE in Iowa community colleges, the impact of community college CTE programs on the state's economy, the role of accountability, and the future implications for CTE in the state are discussed. Recommendations based on the results of the study include improving articulation agreements, increasing retention among at-risk students, and increasing collaboration among Iowa's 15 community colleges.  相似文献   

Building typologies identification to support risk mitigation at the urban scale – Case study of the old city centre of Seixal,Portugal     

Cátia Santos  Tiago Miguel Ferreira  Romeu Vicente  J.A. Raimundo Mendes da Silva 《Journal of Cultural Heritage》2013,14(6):449-463

The old urban centres are marks of an historical and architectural heritage that should be protected and safeguarded. For such, it is fundamental to have a complete understanding of the genesis, regarding both building and the urban mesh. This fact is essential to the support of qualified, conscientious and sustainable rehabilitation interventions on the old building stock. The research carried out addresses the issue of the old urban centres from the perspective of the analysis and inventory of buildings features. The cataloguing process of the building typologies is presented in this work as a synthesis of the principal construction forms, with the old city centre of Seixal being used as a case study. The identification of building typologies has supported a seismic and fire vulnerability assessment of the old building stock. The assessment methodologies developed and used are based on the detailed survey and building inspection, therefore the building typology cataloguing is essential in the analysis at such a large scale. Then we discussed the strategy for the conservation actions incorporated in a broader risk management policy.  相似文献   

Effects of blood flow restriction without additional exercise on strength reductions and muscular atrophy following immobilization:A systematic review

Purpose:To investigate whether blood flow restriction(BFR) without concomitant exercise mitigated strength reduction and atrophy of thigh muscles in subjects under immobilization for lower limbs.Methods:The following databases were searched:PubMed,CINAHL,PEDro,Web of Science,Central,and Scopus.Results:The search identified 3 eligible studies,and the total sample in the identified studies consisted of 38 participants.Isokinetic and isometric torque of the knee flexors and extensors was examined in 2 studies.Cross-sectional area of thigh muscles was evaluated in 1 study,and thigh girth was measured in 2 studies.The BFR protocol was 5 sets of 5 min of occlusion and 3 min of free flow,twice daily for approximately 2 weeks.As a whole,the included studies indicate that BFR without exercise is able to minimize strength reduction and muscular atrophy after immobilization.It is crucial to emphasize,however,that the included studies showed a high risk of bias,especially regarding allocation concealment,blinding of outcome assessment,intention-to-treat analyses,and group similarity at baseline.Conclusion:Although potentially useful,the high risk of bias presented by original stodies limits the indication of BFR without concomitant exercise as an effective countermeasure against strength reduction and atrophy mediated by immobilization.  相似文献
