河南省城镇居民体育消费结构分析   总被引：10，自引：0，他引：10  

王勇 《山东体育学院学报》2003,19(2):81-84

采用问卷调查法，对河南省城镇居民体育消费行为进行调查。结果显示，河南省居民体育消费能力低于全国水平，实物性体育消费占主导地位，观赏性体育消费相对滞后，参与性体育消费有快速增长势头。提出发展河南省城镇居民体育消费的对策。  相似文献

根据中医内科辩证和因时制宜原则 ,对校田径代表队在夏季比赛期间服用活血皇浆前后进行血液动力流变学和血液有形成分参数的比较观察结果表明 ,运动员服液后在脉率 (PR)、每搏量 (SV)、心输出量 (CO)、左心有效泵力 (VPE)和左心能量有效利用率 (EWK )改善的同时 ,出现心肌耗氧量 (HOV)、心肌耗氧指数 (HOI)、心肌血液需要量 (CMBN)、心肌血液灌注量(CMBV)和总周阻 (TPR)、标准周阻 (SPR)、收缩压 (SP)舒张压 (DP)等参数下降 ,呈现机能和能量节省化 ,而血液状态则表现为血容量 (BV)增多 ,全血粘度 (η)和还原血粘度 (ηr)下降 ,切变应力增高 ,血流速度加快 ,有利于维持微循环正常功能。血液有形成分的改变提示 ,血红蛋白 (Hb)红细胞比积 (HCT)和血小板 (PL T)有增高趋势 ;平均红细胞血红蛋白浓度 (MCHC)下降 ,则有可能与 BV相对增多 ,红细胞 (RBC)体积增大有关  相似文献   

Financial support at the time of paper acceptance: a survey of three medical journals     

Sara Schroter  Leanne Tite  Ahmed Kassem 《Learned Publishing》2006,19(4):291-297

The author‐pays model (open access publishing funded through author charges) is dependent on authors having access to financial support at the time their research papers are accepted. We conducted an author survey to determine the availability of external funding for publication charges at different points in the research process. Of the 377/524 (72%) who responded, 62% (233/377) received external funding to support their study, but with notable differences between journals. Only 25% (95/377) could withdraw funds from a grant at the time of paper acceptance. The grant was closed at this time for almost half (105/233, 45%) of those who were externally funded. Non‐externally funded research was largely supported through departmental resources (56%, 80/144) or carrying out research in own time (63%, 91/144). To conclude, a large proportion of published research is not externally funded, and many funded researchers do not have access to financial support at the time their paper is accepted for publication.  相似文献   

Another Look at What Moves Public Opinion: Media Agenda Setting and Polls in the 2000 U.S. Election     

Son  Young Jun; Weaver  David H. 《Int. Journal of Public Opinion Research》2006,18(2):174-197

This study examined two levels of media agenda effects on aggregatepublic opinion from different news sources. The effects wereinvestigated immediately and cumulatively. Content analysisdata from the 2000 U.S. presidential election coverage by fournational news organizations were related to the Gallup pre-electionpoll standings of each candidate. Regression analyses foundthat both the salience of a candidate and the salience of theattributes of a candidate cumulatively, but not immediately,influenced his standing in the polls. An analysis of news sourcessupported the finding that the two levels of agenda-settingeffects seemed mostly cumulative rather than immediate. Newsfrom different sources, however, tended to have effects of differentdegrees and sometimes different directions on candidate pollstandings. Cumulative effects of candidate salience on aggregateopinion change were found for non-partisan and neutral newssources—reporters, poll reporting and public documents—whereasthe effects of candidate attribute salience mostly came frompartisan sources—the candidate himself and members ofthe competing political party. Possible political implicationsof these findings are discussed.  相似文献   

Measuring Cultural Dimensions of Classroom Interactions     

Bryant Jensen  Sara Grajeda  Edward Haertel 《Educational Assessment》2018,23(4):250-276

We trace the development and analyze the generalizability of the Classroom Assessment of Sociocultural Interactions (CASI), an observation system designed to measure cultural dimensions of classroom interactions. We establish CASI measurement properties by analyzing panoramic videos of 4th and 5th grade classrooms from the Measures of Effective Teaching project, and argue for its significance in terms of achievement opportunity for minoritized students and needed evidence regarding equitable teaching. We frame ten dimensions of sociocultural interactions within three domains: Life Applications (i.e., connections with what students know and do outside of school); Self in Group (i.e., interdependence to motivate learning and foster social identities); and Agency (i.e., how freedom and choice are managed).

We demonstrate how measurement error is associated with raters, lessons, and lesson segments, and discuss implications for CASI refinement, as well as appropriate instrument uses to enrich learning opportunities for minoritized students across a variety of classroom settings.  相似文献   

Supportive communication from bystanders of cyberbullying: indirect effects and interactions between source and message characteristics     

Andrew C. High  Rachel Young 《Journal of Applied Communication Research》2018,46(1):28-51

Cyberbullying is an increasingly common experience that produces psychosocial consequences for targets. Interventions encouraging bystanders to support targets of cyberbullying are limited by a lack of focus on what to communicate. This study considers supportive messages that emphasize emotional comfort, attributions of responsibility, and beliefs that people can change as relevant to this context, and it examines how perceptions of messages differ based on whether support providers have or lack experience with cyberbullying. We extend research on the indirect effects model of supportive communication by randomly assigning participants (N?=?304), who self-identify as targets of cyberbullying, to message and source conditions and assessing their perceptions of messages, providers, and outcomes. Impressions of messages mediate their influence on outcomes, and the experiential similarity of support providers moderates these effects. Certain messages, notably those contending that bullies can change, are less effective when delivered by sources who lack experience with bullying.  相似文献   

Crowdfunding for Academic Libraries: Indiana Jones Meets Polka     

Sara Bushong  Susannah Cleveland  Christopher Cox 《The Journal of Academic Librarianship》2018,44(2):313-318

Crowdfunding – or creatively presenting a case for funding to like-minded individuals – is becoming an effective development strategy for academic libraries. The crowdfunding projects described offer multiple approaches to consider, from an adventure-themed video to embracing polka music to entice donors to give. Social media, used in conjunction with the web and well-established email communication formed the basis of successful project promotion. Developing a robust communication plan ahead of campaign launch is critical for success. Thanking donors for their transformational gifts and follow up communication describing the impact of their participation six months later raises friends for the library potentially for many years to come. With proper planning, an active and enthusiastic committee and effective donor stewardship, crowdfunding campaigns will help libraries raise funds to support strategic initiatives.  相似文献
