Directed collaboration patterns in funded teams: A perspective of knowledge flow     

《Information processing & management》2023,60(2):103237

Collaborations in funded teams are essential for understanding funded research and funding policies, although of high interest, are still not fully understood. This study aims to investigate directed collaboration patterns from the perspective of the knowledge flow, which is measured based on the academic age. To this end, we proposed a project-based team identification approach, which gives particular attention to funded teams. The method is applicable to other funding systems. Based on identified scientific teams, we detected recurring and significant subgraph patterns, known as network motifs, and under-represented patterns, known as anti-motifs. We found commonly occurred motifs and anti-motifs are remarkably characterized by different structures matching certain functions in knowledge exchanges. Collaboration patterns represented by motifs favor hierarchical structures, supporting intensive interactions across academic generations. Anti-motifs are more likely to show chain-like structures, hindering potentially various knowledge activities, and are thus seldom found in real collaboration networks. These findings provide new insights into the understanding of funded collaborations and also the funding system. Meanwhile, our findings are helpful for researchers, the public and policymakers to gain knowledge on research(ers) evolution, particularly in terms of primordial collaboration patterns.  相似文献

Beginning and expert supervisors’ cognitions and cognitive structures were compared via concept mapping, a mixed methods design. Both beginning and expert supervisors reported a variety of cognitions representing developmental characteristics in 3 areas: assessment of supervisees, conceptualization and management of supervision, and supervisory relationship.  相似文献   

Genetic Polymorphism of Angiotensin II Type 1 Receptors and Their Effect on the Clinical Outcome of Captopril Treatment in Arab Iraqi Patients with Acute Coronary Syndrome (Mid Euphrates)

Genetic variation in the angiotensin II type 1 receptor (AT1R) has an important effect on the outcome of acute coronary syndrome (ACS) initiated treatment with captopril. This study aims to investigate the impact of genetic polymorphism of AT1R (rs5186 and rs275651) on the ACS outcome in Iraqi patients treated with captopril. A total of 250 Iraqi individuals with ACS were included in this case—control study and they were divided into two study groups; Study group 1 included 125 participants who were prescribed captopril, 25 mg twice daily and study group 2 included 125 participants who received no captopril as part of their ACS treatment (control study). The AT1R gene (rs5186) CC genotype was found to be associated with ST-elevation myocardial infarction (STEMI) (Odd’s ratio (O.R) = 1.2, P = 0.7), while AC was associated with Non-ST-elevation myocardial infarction (NSTEMI) and unstable angina (UA) (O.R = 1.2, P = 0.8). AC genotype is more prone to have Percutaneous coronary intervention (PCI) after ACS attack (O.R = 1.2, P = 0.6). CC genotype had a risk to get less improvement (O.R = 1.6, P = 0.5), so might require higher doses of captopril during acute coronary insult. The AT1R gene (rs275651) AA genotype was associated with UA (O.R = 1.3, P = 0.9). AA and AT genotypes were more prone to have PCI after ACS attack (O.R = 3.9 P = 0.2, O.R = 3.5, P = 0.3 respectively) and thus requiring higher doses of captopril. We conclude that the AT1R rs5186, rs275651 genetic polymorphisms might partially affect the clinical outcome of ACS patients treated with captopril and might have captopril resistance which requires higher doses.  相似文献   

中国体育产业与旅游产业发展耦合关联性测度及空间相关分析     

许金富  陈海春 《山东体育学院学报》2020,(1):9-16

体育产业和旅游产业的互动融合发展是当前经济发展的客观需求,基于耦合协调度模型、探索性空间数据分析方法,构建体育产业和旅游产业发展耦合协调评价指标体系,探讨中国大陆31个省、直辖市、自治区体育产业和旅游产业综合水平及耦合协调度时序、空间分异特征。结果显示:我国体育产业和旅游产业综合水平均表现出增长态势,空间分布呈东中西阶梯分布,旅游产业综合水平好于体育产业水平;耦合协调度发展缓慢,整体处于较低水平;两个产业的耦合协调度在空间上呈正向聚集特征,且聚集程度逐年递增;东部沿海地区耦合协调度好于中部和西部地区。并提出如下建议:建立区域协同发展机制,促进体育产业均衡发展;挖掘体育产业与旅游产业的关联性,完善体育产业发展体系;协同发挥体育产业与旅游产业融合进程中的政府引导作用和企业创新管理能力。  相似文献   

A meta-analytic review of interventions to improve children’s attitudes toward their peers with intellectual disabilities     

《Contemporary educational psychology》2021

Children’s biases toward their peers with intellectual disabilities tend to have negative developmental and social consequences for those with intellectual disabilities. As a result, researchers developed intervention programs to reduce biases toward children with intellectual disabilities. This meta-analysis is a quantitative summary of 59 studies and 144 hypothesis tests involving intervention programs to change children’s attitudes toward their peers with intellectual disabilities. Results revealed an overall significant effect (d = 0.44): following intervention programs, children’s attitudes toward their peers with intellectual disabilities increased. Moderators indicate that the most effective interventions were those that occurred over multiple sessions, involved active engagement in multiple strategies and social interactions, emphasized equal status contact that was unstructured or indirect, and had little adult guidance. Interventions had no effect on changing children’s perceptions of competence and participants in junior high had more negative attitudes following the interventions. Findings provide guidance for researchers, educators, and counselors who seek methodologies to reduce biases toward children with intellectual disabilities.  相似文献

加快体育强国建设已成为一项国策，研究如何提高和建设可持续发展性的体育产业经济以解决人民日益增长的美好体育生活需要和不平衡不充分的发展之间的矛盾对建设体育强国具有重要意义。采用哲学辩证理论分析体育产业经济对体育强国构建的重要性，统计分析目前我国体育产业经济发展现状及其与发达国家的差距，结合十九大新时代背景下给出未来体育产业经济发展策略以期寻求为构建体育强国给出一些指导意见。认为：体育经济是体育强国的重要基石；开展全民健身运动、优化体育产业结构、政府政策导向市场化、跨产业融合增加与其他产业的结合度对构建体育强国具有重要的意义。  相似文献   

Contemporary school knowledge democracy: possible meanings,promising perspectives and necessary prerequisites     

Eleni Katsarou  Konstantinos Sipitanos 《Educational Action Research》2019,27(1):108-124

ABSTRACT

The basic aim of this paper is to discuss the concept ‘Knowledge Democracy’ (KD) and what it can mean in the school context, its implications on knowledge production and dissemination and on the educational practices. We try to enrich this discussion by presenting action research projects to provide case studies of how thinking about KD can reshape educational practice. We consider that the discussion on KD has to be enriched as the concept seems very promising with good prospects towards school’s democratization. On the other hand, as it is quite new, it can encompass internal contradictions that can cause problems at the level of practice. So, we consider very important any contribution to this discussion not as another theoretical sample of the debate on the ‘politics of knowledge’, but because any improvement at the thinking of the issue can be reflected on school practices. Any challenge to traditional politics of knowledge can lead to a deeper understanding of the world of schooling and to transformations through new discourses and new approaches to teaching and learning in school.  相似文献   

基于多系数保角变换法的船舶垂荡纵摇运动仿真     

张腾  任俊生  范小晴  张秀凤 《上海海事大学学报》2019,40(3):51-56

为给航海模拟器建立实用可靠的船舶在波浪中运动的数学模型,基于二维线性势流理论,采用多系数保角变换法对每个船舶横剖面进行高精度拟合,计算各个横剖面的水动力系数和波浪激励力,利用Visual Studio自主开发出船舶在规则波中的纵向运动数值模拟程序。为验证这个数值模拟程序的可靠性,对S175集装箱船在迎浪中运动的幅值响应因子(response amplitude operator, RAO)进行数值计算。结果表明:当弗劳德数为0.275时,RAO计算结果在大部分频率范围内与试验结果吻合良好。因此,这个数值模拟程序能准确地对船舶在波浪中的运动时历进行仿真。  相似文献   

不同收入的城镇居民对体育消费结构和体育消费需求的影响*     

于〓乐  程〓蕾 《广州体育学院学报》2019,(5):26-30

采用问卷调查和数理统计方法，研究了不同收入的居民对体育消费结构和体育消费需求的影响。结果表明，随着居民收入的增加，各类体育消费都呈现上升趋势，实物型体育消费增长速度变慢，观赏型体育消费和健身型体育消费增长速度变快，当居民年收入在10万以上时，观赏型体育消费和健身型体育消费开始急剧增加。制约体育消费需求的主要因素是居民的收入、体育消费的价格、体育消费结构和居民的可支配时间。  相似文献
