Sampling Methods and Sample Populations in Quantitative Mass Communication Research Studies: A 15-Year Census of Six Journals     

Joseph Erba  Brock Ternes  Piotr Bobkowski  Tara Logan  Yuchen Liu 《Communication Research Reports》2018,35(1):42-47

This study evaluated the sampling methods and sample populations used in all U.S.-based survey and experimental mass communication studies published between 2000 and 2014 in six major journals (N = 1,173). Most studies used nonprobability samples, and more than half used student samples. Experiments used more nonprobability and student samples than surveys. Funded studies used more probability and nonstudent samples than nonfunded studies. Implications of results pertaining to population validity and interpretations of findings for mass communication research are discussed.  相似文献

Stepping out: collaborative research across disciplines     

Janet Groen  Tara Hyland-Russell 《International journal of qualitative studies in education》2016,29(6):814-826

This paper offers the experiences and insights of two faculty members, located in two separate disciplines, as they engaged in collaborative research. While knowledge created by stepping out and reaching across disciplines reflects the reality of an increasingly complex world, their experiences highlight both the benefits of a supportive collaborative partnership as well as the risks and discomfort experienced without tangible discipline support, when researchers stray too far from their home discipline. While transparency and attention to process is critical to all researchers engaged in collaborative partnership, its necessity is heightened when venturing beyond the territory of familiar disciplines.  相似文献

Social identification,exercise participation,and positive exercise experiences: Evidence from parkrun     

Mark Stevens  Tim Rees  Remco Polman 《Journal of sports sciences》2019,37(2):221-228

Growing evidence suggests that social identities may have profound implications for physical activity participation. Real-world examinations of this relationship have, however, been lacking, with research predominantly examining intentions and hypothetical scenarios. To address this shortcoming and further advance understanding in this area, the present study tested relationships between group identification, participation, two exercise-specific outcomes (exercise-specific satisfaction and group cohesion), and a broad health indicator (life satisfaction) among individuals recruited from parkrun. Participants (N = 289) completed questionnaires measuring all variables except participants’ parkrun participation, which was objectively assessed. Structural equation modeling demonstrated that group identification was significantly associated with greater participation, exercise-specific satisfaction, group cohesion, and life satisfaction. Findings provide real-world evidence of the health-related benefits associated with forming strong social identities in exercise settings.  相似文献   

创新大数据、创新治理效能和数字化转型     

陈凯华  冯泽  孙茜 《研究与发展管理》2020,32(6):1-12

愈加庞杂的国家创新体系的有效治理迫切需要借助现代科学的方法和手段来支撑，国家创新治理的数字化转型是实现国家创新治理能力现代化、推动创新型国家建设的有效选择。本文从创新治理数字化转型的实践背景与研究背景出发，从多元主体参与、科学性与透明性、精准性、效率、应对与风险防控能力5个维度深入剖析了大数据如何影响国家创新治理，同时从科技发展监测、预见和战略制定、项目与计划管理、活动行为刻画、政策演化和效果跟踪5个方面描述了大数据在国家创新治理体系中的应用情景。最后，就充分发挥利用大数据在创新治理中的作用、实现创新治理的数字化转型提出了相应建议：转变政府创新治理的理念和治理模式、建立多层次创新监测数据整合平台、打通部门间的多层级创新信息孤岛、推行和实施科技创新信息的公开化、建立完善的创新数据管理法规体系、加快推进新型数字基础设施建设。本文为进一步认识大数据在创新引领发展与国家治理体系现代化中的重要支撑作用提供依据。  相似文献
