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   

Can a systematic assessment moderation process assure the quality and integrity of assessment practice while supporting the professional development of casual academics?

There has been a threefold increase in the employment of casual academics in Australian universities within the last 20 years, to the extent that most teaching and marking is now undertaken by casual academics, also known as sessional staff. Yet, casualised teaching and assessment has been considered a risk to student engagement and success, and casual academics report a lack of professional development and increased feelings of marginalisation within the academy. Concurrently, the quality assurance of teaching and assessment in higher education has become a central focus of the government-funded regulatory organisation, the Tertiary Education Quality and Standards Agency (TEQSA). Situated within this context, we report on an assessment moderation process that could support casual academics’ contextualised professional development, generate a sense of connectedness and collegiality and fulfil the requirements of TEQSA. Such processes may ensure that workforce growth in the higher education system supports a robust quality assurance and regulatory framework.  相似文献   

“We must educate our masters”     

Michael Brock 《牛津教育评论》2013,39(3):221-232

In this paper we examine the possible explanations for the patterns of results found at Oxford, in which women students consistently achieve a lower proportion of both first and third class honours. Usual explanations that rest on socio‐biology or simple forms of socialisation are rejected in favour of an explanation which is based on the idea of a mutual determination of social structure and social being. Various hypotheses are proposed as possible explanations of the examination statistics.  相似文献

Increasing plantarflexion angle during landing reduces vertical ground reaction forces,loading rates and the hip’s contribution to support moment within participants     

K. Michael Rowley  James G. Richards 《Journal of sports sciences》2015,33(18):1922-1931

The ankle joint’s role in shock absorption during landing has been researched in many studies, which have found that landing with higher amounts of plantarflexion (PF) results in lower peak vertical ground reaction forces and loading rates. However, there has not yet been a study that compares drop landings within participants along a quantitative continuum of PF angles. Using a custom-written real-time feedback program, participants adjusted their ankles to an instructed PF angle and dropped onto two force platforms. For increasing PF, peak ground reaction force and peak loading rate during weight acceptance decreased significantly. The hip’s contribution to peak support moment decreased as PF at initial contact increased up to 30°. The ankle and knee contributions increased over this same continuum of PF angles. There appears to be no optimal PF angle based on peak ground reaction force and loading rate measurements, but there may be an optimum where joint contributions to peak support moment converge and the hip moment’s contribution is minimised.  相似文献   

A longitudinal examination of African American adolescents' attributions about achievement outcomes     

Swinton AD  Kurtz-Costes B  Rowley SJ  Okeke-Adeyanju N 《Child development》2011,82(5):1486-1500

Developmental, gender, and academic domain differences in causal attributions and the influence of attributions on classroom engagement were explored longitudinally in 115 African American adolescents. In Grades 8 and 11, adolescents reported attributions for success and failure in math, English and writing, and science. In Grade 11, English and mathematics teachers rated students' classroom engagement. Boys were more likely than girls to attribute math successes to high ability and to attribute English failures to low ability. Both genders' ability attributions for math became more negative from eighth to eleventh grades. Grade 8 attributions of math failure to lack of ability were negatively related to Grade 11 math classroom engagement. Results illustrate the gendered nature of motivational beliefs among Black youth.  相似文献

Factors affecting attitudes and intentions towards knowledge sharing in the Dubai Police Force     

Ibrahim Seba  Jennifer Rowley  Sian Lambert 《International Journal of Information Management》2012

This study contributes to the limited research base on knowledge sharing in public sector organisations, specifically police forces, and organisations in the Middle East through a case study investigation into the factors that affect knowledge sharing in the Dubai Police Force. A questionnaire-based survey was conducted with staff in key departments in the Dubai Police Force. Informed by the literature and by interviews conducted in a previous phase, the core of the questionnaire was a bank of Likert-style questions covering the dependent variables intention to knowledge share, and attitude towards knowledge sharing, and the independent variables, trust, organisational structure, leadership, reward, time, and information technology. Data was analysed using structured equation modelling, in order to test the measurement model using confirmatory factor analysis, and to test the structural model. The structural model suggests a strong relationship between attitude to knowledge sharing, and intention to share knowledge. Hypotheses regarding the influence of leadership, trust, organisational structure, time, and information technology on attitude to knowledge sharing were upheld. Rewards did not to influence attitude to knowledge sharing. Recommendations are offered for practice and further research.  相似文献
