突破与瓶颈:女子网球“单飞”职业化改革的反思

"单飞"模式是我国网球职业化改革创举,是网球管理体制改革的突破,这给网球,特别女子网球发展带来根本性变革。随着网球职业化发展进程,"单飞"模式的弊端也在显现,并成为制约网球运动发展瓶颈。所以必须深化网球管理体制改革,破解"单飞"模式的弊端,以使我国女子网球持续发展。     

Effects of Different Exercise Intensities With Isoenergetic Expenditures on C-Reactive Protein and Blood Lipid Levels

We investigated the effects of different exercise intensities on C-reactive protein (CRP), and whether changes in CRP levels correlated with blood lipid levels. Ten men exercised at 25%, 65%, and 85% of their maximum oxygen consumption rates. Participants' blood was analyzed for CRP and blood lipid levels before and after the exercise sessions. Although there was an intensity effect for postexercise high-density lipoprotein levels, there were no significant differences or correlations for postexercise CRP levels or between CRP and lipid levels across the three exercise intensities. In an acute aerobic bout model with isoenergetic expenditures, CRP was not affected by the exercise intensity. Additionally, changes in blood lipid levels might not have been connected to CRP levels for physically fit participants.     

Serological markers of inflammatory bowel disease

Inflammatory bowel disease (IBD) is a heterogeneous group of chronic inflammatory disorders of the gastrointestinal tract with two main distinguishable entities, Crohn’s disease (CD) and ulcerative colitis (UC). IBD-unclassified (IBD-U) is a diagnosis that covers the “grey” zone of diagnostic uncertainty between UC and CD. Current diagnosis of IBD relies on the clinical, endoscopic, radiological, histological and biochemical features, but this approach has shortcomings especially in cases of overlapping symptoms of CD and UC. The need for a diagnostic tool that would improve the conventional methods in IBD diagnosis directed the search towards potential immunological markers, since an aberrant immune response against microbial or endogenous antigens in a genetically susceptible host seems to be implicated in IBD pathogenesis. The spectrum of antibodies to different microbial antigens and autoantibodies associated with IBD is rapidly expanding. Most of these antibodies are associated with CD like anti-glycan antibodies: anti-Saccharomices cerevisiae (ASCA) and the recently described anti-laminaribioside (ALCA), anti-chitobioside (ACCA), anti-mannobioside (AMCA), anti-laminarin (anti-L) and anti-chitin (anti-C) antibodies; in addition to other antibodies that target microbial antigens: anti-outer membrane porin C (anti-OmpC), anti-Cbir1 flagellin and anti-I2 antibody. Also, autoantibodies targeting the exocrine pancreas (PAB) were shown to be highly specific for CD. In contrast, UC has been associated with anti-neutrophil cytoplasmic autoantibodies (pANCA) and antibodies against goblet cells (GAB). Current evidence suggests that serologic panels of multiple antibodies are useful in differential diagnosis of CD versus UC and can be a valuable aid in stratifying patients according to disease phenotype and risk of complications.

Exploring the Role of Identity in Māori Heritage Language Learner Motivations

Substantially less is known about the motivations of indigenous heritage language learners than the motivations of learners of colonial languages. This study explores the motivations of Māori indigenous New Zealanders and the identity-related motivations they have for learning their heritage language. Interviews with 19 Māori language learners revealed that identity was a central motivation for both initiating the task of language learning and sustaining the behaviour. Rather than applying intrinsic/extrinsic dichotomies to understand Māori motivations, a relational framework was articulated. Māori, who are described as relationally oriented, were commonly motivated to learn the language as a means of building relationships with others in their cultural ingroup. There were also expectations that Māori were able to perform cultural roles using the language. This study confirmed that the pressures on indigenous learners to maintain a language for cultural continuation are quite separate from the motivations of learners of colonial languages.     

Gender Differences in the Developmental Cascade From Harsh Parenting to Educational Attainment: An Evolutionary Perspective

This study utilized life history theory to test a developmental cascade model linking harsh parenting to low educational attainment. Multigroup models were examined to test for potential gender differences. The sample consisted of 1,482 adolescents followed up for 9 years starting in seventh grade (M_age = 12.74). Results supported indirect links between harsh parenting and low educational attainment through the development of extreme peer orientations, early sexual behavior, and delinquency. Among male adolescents, harsh parenting was related to the development of an extreme peer orientation, which further led to increased delinquency, and subsequently lower educational attainment. Among female adolescents, harsh parenting predicted extreme peer orientations, which increased both delinquency and early sexual behavior. Early sexual behavior further predicted lower educational attainment in female adolescents.     

我国高校开展田径教学的困境与机遇

高校体育教学改革进行多年,以往最为普及的田径在教学中由于受传统观念的制约,使学生难以接受,于是逐渐退出高校体育教学,而快乐体育成为主流。但是经过多年的实践发现,健康第一的教育宗旨没有实现,学生的体质状况连年下降。研究表明只要从实际出发,使田径课程的改革既要增进健康,又能满足学生的需要和兴趣,田径一定能重返高校体育教学。
