It happens all the time,you just don't take any notice     

Delia Hart 《International Journal of Inclusive Education》2013,17(4):327-340

This article discusses research undertaken with a group of ten adolescent school girls about their understandings and perceptions of sexual harassment. The research took place 2 years after the Department of Education, Queensland, had developed and disseminated its Sexual Harassment Policy and Grievance Procedures (1994). In a series of interviews, the research participants revealed their understandings of sexual harassment and the factors they considered when making the decision to report sexual harassment and/or to utilize existing grievance procedures. The research indicates that the elimination of sexual harassment must take into account the complexities and ambiguities at work in the school lives of adolescent girls. At present it would appear that schools are driven by the legal imperative to implement policy, and have yet to focus on the educative responsibility attending the policy. Schools’ educative responsibility for the effective implementation of sexual harassment policy requires that students have opportunities to examine in the formal curriculum a range of discourses that expose the contradictory ways in which gender, power, sexuality and desire are constructed in education and schooling. The findings of this research therefore have significant implications for school communities, curriculum developers and policy makers  相似文献   

Addressing the Needs of the Homeless: A San José Library Partnership Approach     

Lydia N. Collins  Francis Howard  Angie Miraflor 《The Reference Librarian》2013,54(1):109-116

Describes an urban joint-use library's approaches to library programs for homeless children, teens, and adults as well as agencies the library could partner with. Proposes that libraries put more effort into reaching out to the homeless community instead of assuming the normal expectation that people will come to the library.  相似文献   

Playing Soccer on the Football Field: The Persistence of Gender Inequities for Women Faculty     

Christine M. Cress  Jeni Hart 《Equity & Excellence in Education》2013,46(4):473-488

Sports metaphor is employed as an epistemic tool for describing psychological, sociocultural, and organizational factors that contribute to enduring gender bias, inequalities, and discrimination faced by women faculty at colleges and universities. Quantitative and qualitative data from two comprehensive institutional campus climate studies show that women and men faculty experience their work lives differently. Based upon our analyses, we argue for restructuring the embedded normative values and processes that inform the academic playbook.  相似文献

Effect of a Marathon Run on Serum Lipoproteins,Creatine Kinase,and Lactate Dehydrogenase in Recreational Runners     

Philip K. Schot  Barbara A. Hart  Michael Mueller 《Research quarterly for exercise and sport》2013,84(4):450-456

Abstract

The objective of this study was to determine the effect of a marathon run on serum lipid and lipoprotein concentrations and serum muscle enzyme activities and follow their recovery after the run. These blood concentrations were measured before, immediately after, and serially after a marathon run in 15 male recreational runners. The triglyceride level was significantly elevated postrace, then fell 30% below baseline 1 day after the run, and returned to baseline after 1 week. Total cholesterol responded less dramatically but with a similar pattern. High-density lipoprotein cholesterol remained significantly elevated and low-density lipoprotein cholesterol was transiently reduced for 3 days after the run. The total cholesterol/high-density cholesterol ratio was significantly lowered for 3 days. Serum lactate dehydrogenase activity significantly doubled postrace and then declined but remained elevated for 2 weeks. Serum creatine kinase activity peaked 24 hr after the run, with a 15-fold rise, and returned to baseline after 1 week. The rise of these enzymes reflects mechanically damaged muscle cells leaking contents into the interstitial fluid. It is concluded that a prolonged strenuous exercise bout in recreational runners, such as a marathon, produces beneficial changes in lipid blood profiles that are significant for only 3 days. However, muscle damage is also evident for 1 week or more from the dramatic and longlasting effect on enzyme levels. Laboratory values for these runners were outside normal ranges for some days after the race.  相似文献   

SCHOOL DELINQUENCY AND SOCIAL BOND FACTORS: EXPLORING GENDERED DIFFERENCES AMONG A NATIONAL SAMPLE OF 10TH GRADERS     

Caroline O. Hart  Christian E. Mueller 《Psychology in the schools》2013,50(2):116-133

School delinquency has been linked to an array of negative educational outcomes, and if left unchecked, may lead to more serious problems in adulthood. Identifying the risk and protective factors that influence school delinquency is therefore crucial to develop effective intervention programs. Utilizing Hirschi's social bond theory as a framework, the authors investigated the relationships between social bonds (i.e., parental involvement, bond to school, beliefs, commitment to sport activities, commitment to non‐sport activities, and involvement) and school delinquency among a nationally representative sample of 10th graders. Special attention was given to gender differences. Results indicate that social bond measures account for a significant variance in school delinquency (11.2%, p < .001) above and beyond that predicted by socioeconomic status (1.5%, p < .001), and that the relationships between social bonds and school delinquency vary across gender. Practical and theoretical implications are for educators and researchers alike.  相似文献   

Cascade optical chromatography for sample fractionation     

Alex Terray  Joseph D. Taylor    Sean J. Hart 《Biomicrofluidics》2009,3(4)

Optical chromatography involves the elegant combination of opposing optical and fluid drag forces on colloidal samples within microfluidic environments to both measure analytical differences and fractionate injected samples. Particles that encounter the focused laser beam are trapped axially along the beam and are pushed upstream from the laser focal point to rest at a point where the optical and fluid forces on the particle balance. In our recent devices particles are pushed into a region of lower microfluidic flow, where they can be retained and fractionated. Because optical and fluid forces on a particle are sensitive to differences in the physical and chemical properties of a sample, separations are possible. An optical chromatography beam focused to completely fill a fluid channel is operated as an optically tunable filter for the separation of inorganic, polymeric, and biological particle samples. We demonstrate this technique coupled with an advanced microfluidic platform and show how it can be used as an effective method to fractionate particles from an injected multicomponent sample. Our advanced three-stage microfluidic design accommodates three lasers simultaneously to effectively create a sequential cascade optical chromatographic separation system.  相似文献   

Single view silhouette fitting techniques for estimating tennis racket position     

Nathan Elliott  Simon Choppin  Simon Goodwill  Terry Senior  John Hart  Tom Allen 《Sports Engineering》2018,21(2):137-147

Stereo camera systems have been used to track markers attached to a racket, allowing its position to be obtained in three-dimensional (3D) space. Typically, markers are manually selected on the image plane, but this can be time-consuming. A markerless system based on one stationary camera estimating 3D racket position data is desirable for research and play. The markerless method presented in this paper relies on a set of racket silhouette views in a common reference frame captured with a calibrated camera and a silhouette of a racket captured with a camera whose relative pose is outside the common reference frame. The aim of this paper is to provide validation of these single view fitting techniques to estimate the pose of a tennis racket. This includes the development of a calibration method to provide the relative pose of a stationary camera with respect to a racket. Mean static racket position was reconstructed to within ±2 mm. Computer generated camera poses and silhouette views of a full size racket model were used to demonstrate the potential of the method to estimate 3D racket position during a simplified serve scenario. From a camera distance of 14 m, 3D racket position was estimated providing a spatial accuracy of 1.9 ± 0.14 mm, similar to recent 3D video marker tracking studies of tennis.  相似文献
