This completely computer-based module''s purpose is to introduce students to bioinformatics resources. We present an easy-to-adopt module that weaves together several important bioinformatic tools so students can grasp how these tools are used in answering research questions. Students integrate information gathered from websites dealing with anatomy (Mouse Brain Library), quantitative trait locus analysis (WebQTL from GeneNetwork), bioinformatics and gene expression analyses (University of California, Santa Cruz Genome Browser, National Center for Biotechnology Information''s Entrez Gene, and the Allen Brain Atlas), and information resources (PubMed). Instructors can use these various websites in concert to teach genetics from the phenotypic level to the molecular level, aspects of neuroanatomy and histology, statistics, quantitative trait locus analysis, and molecular biology (including in situ hybridization and microarray analysis), and to introduce bioinformatic resources. Students use these resources to discover 1) the region(s) of chromosome(s) influencing the phenotypic trait, 2) a list of candidate genes—narrowed by expression data, 3) the in situ pattern of a given gene in the region of interest, 4) the nucleotide sequence of the candidate gene, and 5) articles describing the gene. Teaching materials such as a detailed student/instructor''s manual, PowerPoints, sample exams, and links to free Web resources can be found at http://mdcune.psych.ucla.edu/modules/bioinformatics.  相似文献   

Badminton shuttlecock aerodynamics: synthesizing experiment and theory   总被引：2，自引：1，他引：1  

Chak Man Chan  Jenn Stroud Rossmann 《Sports Engineering》2012,15(2):61-71

In this study, the flight performance of four models of shuttlecocks, two with feather skirts and two with plastic, is investigated. The aerodynamic forces of each shuttlecock at varying air speed and angle of attack are measured in a subsonic wind tunnel. Empirical correlations derived from these data are then incorporated into an adaptive, shuttlecock-specific numerical trajectory simulation. These simulated trajectories are in good agreement with experimental results, with average and maximum errors of 2.5 and 9.1% in vertical distance travelled. The aerodynamically adaptive trajectory model is used to analyse four common types of badminton shot: serve, net, smash and high clear. From these simulations, it is found that the trajectory paths of the higher quality plastic shuttlecock most closely mimic those of the feather shuttlecock of same speed grade. Results of both aerodynamic testing and trajectory simulation provide quantitative support for players?? preference for the ??feel?? and responsiveness of feather shuttlecocks. It is also observed that plastic shuttlecocks fly faster than do feather shuttlecocks under smash shots, a behaviour explained by a reduction of drag due to skirt deformation observed in wind tunnel experiments at high flight velocity. The results of the study highlight the influence of shuttlecock design and material on shuttlecock flight.  相似文献   

Conceptualising and testing the relationship between actual and perceived motor performance: A cross-cultural comparison in children from Australia and Germany

ABSTRACT

Previous studies investigating the relationship between motor skill, physical activity and fitness in children have not thoroughly considered the role of self-perception. Therefore, the study aim was to test a theoretical framework, which considered both actual and perceived motor skill as well as actual and perceived fitness. Potential moderating effects of sex and country were considered. Data on motor skill, fitness, as well as self-perception of motor skill and fitness were collected from 145 Australian children and 214 German children (age range 7 to 10 years). For actual motor skill and fitness, mean differences for sex, age and country were found. For perceived motor performance (perceived motor skill and perceived fitness) no mean differences were found for age. Path analyses were performed. The final model showed significant relations between actual performance (object control skill, fitness) and perceived performance (object control skill, fitness). All model paths had low to moderate regression weights with the lowest relationship reported between actual and perceived fitness. Sex and country showed no effects. This integrated approach has led to a better understanding of the relationship between children’s perceived and objective performance, and cultural differences within them.  相似文献

Impact of primary and secondary social origin factors on the transition to university in the Czech Republic     

Natalie Simonová  Petr Soukup 《British Journal of Sociology of Education》2015,36(5):707-728

The main objective of this paper is to show to what extent and why students with the same academic aptitude but different social backgrounds have different odds of entering university. For our analysis, we separated primary and secondary factors of social origin in the formation of educational inequalities. The results show that the primary and secondary factors have approximately the same influence on the transition to university. Czech schools do not affect the process of forming educational aspirations and transition to university, and merely ‘classify’ children according to their social origin. This situation emerged during the socialist era and has remained unchanged after the fall of communism (in 1989). However, the mechanism of the social origin effect has changed – while cultural capital with a ‘direct’ impact had a major role to play during the socialist era, at present there is a rather ‘indirect’ influence through economic capital.  相似文献   

Searching for New Answers: The Application of Task‐Technology Fit to E‐Textbook Usage          下载免费PDF全文

Natalie Gerhart  Daniel A. Peak  Victor R. Prybutok 《Decision Sciences Journal of Innovative Education》2015,13(1):91-111

Students have been slow to adopt e‐textbooks even though they are often less expensive than traditional textbooks. Prior e‐textbook research has focused on adoption behavior, with little research to date on how students perceive e‐textbooks fitting their needs. This work builds upon Task‐Technology Fit (TTF) and Consumer Acceptance and Use of Technology (UTAUT2) theory to present a student‐perspective model of e‐textbook usage. By contextualizing TTF and UTAUT2 to e‐textbooks, the research fills a gap in the literature and provides guidance to researchers and practitioners. The goal of the research is to understand how students perceive their task of learning to fit with e‐textbook technology, and how that fit influences e‐textbook usage and expected performance in their classes. To achieve this goal, the research develops a model to test the relationship between perceived TTF of e‐textbooks and UTAUT2‐defined user characteristics that encourage adoption behaviors, thus facilitating student learning. The findings show that four factors impact a student's perceived TTF: substitution, habit, hedonic motivation, and facilitating conditions. Furthermore, perceived TTF positively correlates with students’ e‐textbook usage and expected performance in classes when using e‐textbooks. While price value exhibits a measurable effect on e‐textbook utilization, it is a minor factor.  相似文献

A qualitative study of the impact of the London 2012 Olympics on families in the East Midlands of England: lessons for sports development policy and practice     

Chris Mackintosh  Natalie Darko  Zoe Rutherford  Hetty-May Wilkins 《Sport, Education and Society》2015,20(8):1065-1087

The dynamics and culture of families are central to individual and community sport and physical activity participation. This research project examined the lived experiences and day-to-day realities of the London 2012 Olympics from the perspectives of five families in the East Midlands region of England. The aims of the project were to assess the influence the Games had on shaping family sports participation, influencing social and health relationships within the families through sports and reactions to the 2012 Olympics. The study was conducted through the generation of rich qualitative data from pre- and post-Games interviews as well as production of video diary data by the families and young people themselves to gather micro-level information on the realities of ‘legacy’ for families. Findings from this research project illustrate that prior parental socialisation into sport shaped current attitudes to legacy and children and mothers and fathers had mixed reactions to the actual presence of legacy. There are also clear sports development challenges around accessibility, cost, project design, the non-family-friendly nature of some schemes present during the potential consumption of legacy that have consequences for future research in this embryonic area. Implications from the study include the need to locate the family as a more central concern for policy makers in sports development practice. The study has questioned the assumed virtuous legacy of the London 2012 Games from the perspective of families on a day-to-day micro-level. Instead, a far more complex and diverse picture from the perspective of the family has been presented that requires further critical research on this little explored topic of policy and practice in sports development.  相似文献   

How Birth Doulas Help Clients Adapt to Changes in Circumstances,Clinical Care,and Client Preferences During Labor     

Natalie Lea Amram  Michael C. Klein  Heidi Mok  Penny Simkin  Kathie Lindstrom  Jalana Grant 《The Journal of perinatal education》2014,23(2):96-103

This study examined how doulas adapt to challenges in client’s labors. There were 104 Canadian and 92 American doulas who responded to a survey distributed at a doula conference. We report results from open-ended questions in which doulas describe how they manage changes deviating from the mother’s birth plan and how they navigate differences of opinion between themselves and providers. Four themes emerged: giving nonjudgmental support, assisting informed decision making, acting as a facilitator, and issues with advocacy. Although 30% of doulas said that advocacy and information giving could result in conflict with providers, doulas reported working within their scope of practice and striving to be part of the team. Issues in doula responsibility and patient advocacy remain, and ongoing role clarification is needed.  相似文献
