Effect of biological maturation on maximal oxygen uptake and ventilatory thresholds in soccer players: an allometric approach     

Cunha G  Lorenzi T  Sapata K  Lopes AL  Gaya AC  Oliveira Á 《Journal of sports sciences》2011,29(10):1029-1039

In this study, we investigated the effect of biological maturation on maximal oxygen uptake ([Vdot]O(2max)) and ventilatory thresholds (VT(1) and VT(2)) in 110 young soccer players separated into pubescent and post-pubescent groups.. Maximal oxygen uptake and [Vdot]O(2) corresponding to VT(1) and VT(2) were expressed as absolute values, ratio standards, theoretical exponents, and experimentally observed exponents. Absolute [Vdot]O(2) (ml · min(-1)) was different between groups for VT(1), VT(2), and [Vdot]O(2max). Ratio standards (ml · kg(-1) · min(-1)) were not significantly different between groups for VT(1), VT(2), and [Vdot]O(2max). Theoretical exponents (ml · kg(-0.67) · min(-1) and ml · kg(-0.75) · min(-1)) were not properly adjusted for the body mass effects on VT(1), VT(2), and [Vdot]O(2max). When the data were correctly adjusted using experimentally observed exponents, VT(1) (ml · kg(-0.94) · min(-1)) and VT(2) (ml · kg(-0.95) · min(-1)) were not different between groups. The experimentally observed exponent for [Vdot]O(2max) (ml · kg(-0.90) · min(-1)) was different between groups (P = 0.048); however, this difference could not be attributed to biological maturation. In conclusion, biological maturation had no effect on VT(1), VT(2) or [Vdot]O(2max) when the effect of body mass was adjusted by experimentally observed exponents. Thus, when evaluating the physiological performance of young soccer players, allometric scaling needs to be taken into account instead of using theoretical approaches.  相似文献   

Adjustment to College as Measured by the Student Adaptation to College Questionnaire: A Quantitative Review of its Structure and Relationships with Correlates and Consequences     

Marcus Credé  Sarah Niehorster 《Educational Psychology Review》2012,24(1):133-165

This paper presents a meta-analytic review (k = 237, N = 44,668) of the adjustment to college literature. The review, based on studies using the Student Adaptation to College Questionnaire, is organized around three primary themes: (1) the structure of students’ adjustment to college, (2) the relationship of adjustment to college constructs with possible antecedents and correlates, and (3) the relationship of adjustment to college constructs with college grades and college retention. Meta-analytic results indicate that adjustment to college is multidimensional, predictive of college grades, and an unusually good predictor of college retention. Adjustment to college is also shown to be moderately related to individual traits, social support, and students’ relationships with their parents. Weaker relationships are evident with demographic variables, prior achievement, coping approaches, and variables that reflect students’ psychological independence from their parents. Theoretical and practical implications for the study of students’ adjustment to college, academic performance, and retention are discussed.  相似文献

Building communities in higher education: the case of nursing     

Nicola Andrew  Amélia Lopes  Fátima Pereira  Ilda Lima 《Teaching in Higher Education》2013,18(1):72-77

The historic and current case to retain a focused clinical nursing identity within an academic context is explicit; however there is tension between the need for excellence in teaching and research, and obligation to maintain a credible clinical identity. Nursing is politically and vocationally advanced but, arguably, weaker academically. Considered an ‘old vocation’ but a ‘young discipline’, nursing lacks the traditional background found in established academic communities. Nurses still find it difficult to ‘let go’ of the past and new academics will often try to re-create a clinical role because they lack confidence in their ability to fulfil an academic one. Moving forward, the new graduate nursing programmes and the growing number of hybrid or ‘pracademic’ roles spanning education and practice will, through the co-creation of knowledge, challenge discipline boundaries and produce a new generation of leaders for the profession.  相似文献   

Effects of Reward on Self‐regulation,Intrinsic Motivation and Creativity     

Marcus Selart  Thomas Nordström  Bård Kuvaas  Kazuhisa Takemura 《Scandinavian Journal of Educational Research》2013,57(5):439-458

This article evaluates the effects of two types of rewards (performance‐contingent versus engagement‐contingent) on self‐regulation, intrinsic motivation and creativity. Forty‐two undergraduate students were randomly assigned to three conditions; i.e. a performance‐contingent reward group, an engagement‐contingent reward group and a control group. Results provide little support for the negative effects of performance rewards on motivational components. However, they do indicate that participants in the engagement‐contingent reward group and the control group achieved higher rated creativity than participants in the performance‐contingent reward group. Alternative explanations for this finding are discussed.  相似文献   

Deliberating International Science Policy Controversies: Uncertainty and AIDS in South Africa     

Marcus Paroske 《Quarterly Journal of Speech》2013,99(2):148-170

International science policy controversies involve disputes over cultural differences in the assessment of knowledge claims and competing visions of the policy-making process between different nations. This essay analyzes these dynamics in the recent controversy surrounding AIDS policy in South Africa. It develops the notion of an epistemological filibuster, an appeal to uncertainty in order to delay policy implementation, and shows the key role it played in producing an argumentative stalemate between President Thabo Mbeki and Western orthodox AIDS scientists that threatened millions of HIV-positive South Africans.  相似文献
