Nutrition guidelines for strength sports: sprinting, weightlifting, throwing events, and bodybuilding     

Slater G  Phillips SM 《Journal of sports sciences》2011,29(Z1):S67-S77

Strength and power athletes are primarily interested in enhancing power relative to body weight and thus almost all undertake some form of resistance training. While athletes may periodically attempt to promote skeletal muscle hypertrophy, key nutritional issues are broader than those pertinent to hypertrophy and include an appreciation of the sports supplement industry, the strategic timing of nutrient intake to maximize fuelling and recovery objectives, plus achievement of pre-competition body mass requirements. Total energy and macronutrient intakes of strength-power athletes are generally high but intakes tend to be unremarkable when expressed relative to body mass. Greater insight into optimization of dietary intake to achieve nutrition-related goals would be achieved from assessment of nutrient distribution over the day, especially intake before, during, and after exercise. This information is not readily available on strength-power athletes and research is warranted. There is a general void of scientific investigation relating specifically to this unique group of athletes. Until this is resolved, sports nutrition recommendations for strength-power athletes should be directed at the individual athlete, focusing on their specific nutrition-related goals, with an emphasis on the nutritional support of training.  相似文献   

Masculinity, moral atmosphere, and moral functioning of high school football players     

Steinfeldt JA  Rutkowski LA  Vaughan EL  Steinfeldt MC 《运动与训练心理学杂志》2011,33(2):215-234

In order to identify factors associated with on-field moral functioning among student athletes within the unique context of football, we examined masculine gender role conflict, moral atmosphere, and athletic identity. Using structural equation modeling to assess survey data from 204 high school football players, results demonstrated that moral atmosphere (i.e., the influence of coaches and teammates) was significantly associated with participants' process of on-field moral functioning across the levels of judgment, intention, and behavior. Neither masculine gender role conflict nor athletic identity significantly predicted moral functioning, but the results indicated that participants' identification with the athlete role significantly predicted conflict with socialized gender roles. Results suggest that in the aggressive and violent sport of football, coaches can have a direct influence on players' moral functioning process. Coaches can also have an indirect effect by influencing all the players so that a culture of ethical play can be cultivated among teammates and spread from the top down.  相似文献   

Professional and Technical Communication in a Web 2.0 World     

Stuart Blythe  Claire Lauer  Paul G. Curran 《Technical Communication Quarterly》2014,23(4):265-287

This article reports on results of a nationwide survey of alumni in professional and technical communication. It presents a series of snapshots from the results, including the types of texts written and valued, where those types are written, with and for whom, and with what technologies. A range of implications are explored.  相似文献   

Assessing Outcomes: Practical Methods and Evidence          下载免费PDF全文

Jon Moore  Jesse Owen 《Journal of College Counseling》2014,17(2):175-185

University counseling center clients’ (N = 52) perceptions of precounseling functioning were highly correlated with their actual well‐being scores at intake. The magnitude of change based on perceptions of precounseling functioning to current well‐being was approximately double of what is found from the difference of actual precounseling well‐being to current well‐being scores. Retrospective methods for assessing precounseling functioning are best suited for comparison among clients or counseling processes.  相似文献   

Beyond Punnett Squares: Student Word Association and Explanations of Phenotypic Variation through an Integrative Quantitative Genetics Unit Investigating Anthocyanin Inheritance and Expression in Brassica rapa Fast Plants

Genetics instruction in introductory biology is often confined to Mendelian genetics and avoids the complexities of variation in quantitative traits. Given the driving question “What determines variation in phenotype (Pv)? (Pv=Genotypic variation Gv + environmental variation Ev),” we developed a 4-wk unit for an inquiry-based laboratory course focused on the inheritance and expression of a quantitative trait in varying environments. We utilized Brassica rapa Fast Plants as a model organism to study variation in the phenotype anthocyanin pigment intensity. As an initial curriculum assessment, we used free word association to examine students’ cognitive structures before and after the unit and explanations in students’ final research posters with particular focus on variation (Pv = Gv + Ev). Comparison of pre- and postunit word frequency revealed a shift in words and a pattern of co-occurring concepts indicative of change in cognitive structure, with particular focus on “variation” as a proposed threshold concept and primary goal for students’ explanations. Given review of 53 posters, we found ∼50% of students capable of intermediate to high-level explanations combining both Gv and Ev influence on expression of anthocyanin intensity (Pv). While far from “plug and play,” this conceptually rich, inquiry-based unit holds promise for effective integration of quantitative and Mendelian genetics.  相似文献   

Characterizing University Library Use of Social Media: A Case Study of Twitter and Facebook from Australia     

Stuart Palmer 《The Journal of Academic Librarianship》2014,40(6):611-619

The work presented here characterise the engagement of one university library with two social media platforms popular with academic libraries. The collected data are analysed to identify the forms of Twitter and Facebook activity that engage library stakeholders in social media conversations. Associations were observed between: i) directed tweets from the library and mentions of the library by others on Twitter; and ii) comments from the library and comments from others on Facebook. Three broad classes of Twitter user interacting with the library were revealed: i) accounts strongly linked to the library with multiple to/from tweets; ii) those weakly linked to the library with, typically, a single tweet; and iii) those indirectly linked to the library through tweets mentioning the library and sent by other users. Two divergent forms of Facebook interaction with the library were highlighted: i) a library post generating a large sequence of comments, typically in response to a competition/challenge; and ii) a library post with no comments, typically a photo post or a post inviting readers to click a link to find out more about an event/service. The work presented here is an initial investigation that provides useful insights, and offers a methodology for future research.  相似文献

The Warren Cup: Highlighting Hidden Histories     

Stuart Frost 《The International Journal of Art & Design Education》2007,26(1):63-72

Contemporary artists and art galleries have been more active than museums in representing gay and lesbian culture in public spaces in recent decades. However same‐sex relationships have a long history that is reflected in the collections of museums that have material from the classical world. The culture of ancient Greece and Rome was less inhibited about the representation of sexual acts than many nineteenth‐century museums would have liked. Objects with frank images of sexual acts were discreetly censored or hidden away in secret cabinets. This article draws on one object as a case study, a Roman silver cup dated to the early years of the first century AD acquired by the British Museum in 1999. The cup is decorated with beautifully realised scenes in relief decoration which show two pairs of males engaged in love‐making, each pair consisting of one older male and a youth. The object could never have been acquired or publicly displayed earlier in the twentieth century. The vessel known as the Warren Cup (after a previous owner) provides a provocative stimulus for debate about male‐to‐male lovemaking. Discussion of the meaning of the scenes, and the possible reasons why they were represented on such a high‐status object, generates more questions than answers. This uncertainty contributes to the power of this object to open up debate. This article will raise questions for educators and students to consider about the Cup, an object which society has only recently ceased to regard as pornographic or obscene.  相似文献
