September 11 and the failures of American intellectuals     

Robert Jensen 《传播与批判/文化研究》2013,10(1):80-88

This essay critiques the main responses to 9/11 by US intellectuals and analyzes how these reactions reinforced a determined ignorance of the consequences of US economic, foreign, and military policy and a further depoliticization of the culture in general. As a class, faculty have the resources—material and intellectual—to make a serious contribution to progressive political and social change in the world. They need to start putting those resources to work.  相似文献   

Comparing Theories of Media Learning: Cognitive Mediation,Information Utility,and Knowledge Acquisition from Cancer News     

Andy J. King  Jakob D. Jensen  Nick Carcioppolo  Melinda M. Krakow  Ye Sun 《Mass Communication and Society》2013,16(6):753-775

Determining what factors predict media learning is an important avenue of research for the field of mass communication. The present study provides a comparative investigation of two models of media learning: the cognitive mediation model and the information utility model. Participants (N = 1,076) read a news article related to scientific discoveries relevant to cancer prevention and responded to all constructs of the two models. Recognition and comprehension were used to measure knowledge acquisition. Results generally support previous predictions of each model, though predicted variance remains small. In addition to testing the existing models, a modified cognitive mediation model using a key construct related to information utility—perceived relevance—was tested. The refined cognitive mediation model offered a more nuanced understanding of certain causal mechanisms but did not result in a meaningful change in predictive power of the model. Implications of the theoretical comparison and integration are discussed.  相似文献   

Feminists of faith: Sonia Johnson and the Mormons for ERA     

Richard J. Jensen  John C. Hammerback 《Communication Studies》2013,64(3):123-137

The Mormons for ERA is analyzed in this essay as an innovational movement. In this way, Sonia Johnson's appeals to mainstream Mormons before her excommunication can he understood as reformist discourse which became radicalized only in a second stage.  相似文献   

Caveats for using statistical significance tests in research assessments     

Jesper W. Schneider 《Journal of Informetrics》2013,7(1):50-62

This article raises concerns about the advantages of using statistical significance tests in research assessments as has recently been suggested in the debate about proper normalization procedures for citation indicators by Opthof and Leydesdorff (2010). Statistical significance tests are highly controversial and numerous criticisms have been leveled against their use. Based on examples from articles by proponents of the use statistical significance tests in research assessments, we address some of the numerous problems with such tests. The issues specifically discussed are the ritual practice of such tests, their dichotomous application in decision making, the difference between statistical and substantive significance, the implausibility of most null hypotheses, the crucial assumption of randomness, as well as the utility of standard errors and confidence intervals for inferential purposes. We argue that applying statistical significance tests and mechanically adhering to their results are highly problematic and detrimental to critical thinking. We claim that the use of such tests do not provide any advantages in relation to deciding whether differences between citation indicators are important or not. On the contrary their use may be harmful. Like many other critics, we generally believe that statistical significance tests are over- and misused in the empirical sciences including scientometrics and we encourage a reform on these matters.  相似文献   

Sympathoadrenal and parasympathetic responses to exercise     

Niels Holmqvist  Niels H. Secher  Kåre Sander‐Jensen  Ulrich Knigge  J⊘rgen Warberg  Thue W. Schwartz 《Journal of sports sciences》2013,31(2):123-128

Exhaustive exercise is associated with a persistent sensation of weakness and sometimes nausea suggesting abdominal vagal activity. We measured plasma indices of sympathoadrenal (adrenaline, noradrenaline, dopamine) and vagal (pancreatic polypeptide) activity before, during and after submaximal and maximal exercise in healthy young subjects. Plasma adrenaline, noradrenaline and dopamine increased to 8.5 (range 7.4–40.5), 48.0 (32.3–100.5) and 1.8 (1.2–6.6) nmol l^–1 respectively (n = 5), during maximal exercise and decreased towards control values within 15 min of rest. Pancreatic polypeptide (n = 10) increased only during maximal exercise and reached its highest value, 48 (21–145) pmol l^–1, after exertion. The results conform to an increase in sympathetic activity during exercise and a persistent vagal activity after intense exercise which could contribute to the sensation of weakness.  相似文献   

Enhanced learning through design problems – teaching a components-based course through design     

Bogi Bech Jensen  Stig Högberg  Frida av Fløtum Jensen  Nenad Mijatovic 《European Journal of Engineering Education》2012,37(4):375-382

This paper describes a teaching method used in an electrical machines course, where the students learn about electrical machines by designing them. The aim of the course is not to teach design, albeit this is a side product, but rather to teach the fundamentals and the function of electrical machines through design. The teaching method is evaluated by a student questionnaire, designed to measure the quality and effectiveness of the teaching method. The results of the questionnaire conclusively show that this method labelled ‘learning through design’ is a very effective way of teaching a components-based course. This teaching method can easily be generalised and used in other courses.  相似文献

Professional Development and Its Impact on Children in Early Childhood Education and Care: A Meta-Analysis Based on European Studies     

Peter Jensen 《Scandinavian Journal of Educational Research》2013,57(6):935-950

This study reviews the European evidence on the impact of professional development (PD) of pre-school educators on child outcomes. A meta-analysis investigates how PD of pre-school educators in formal pre-school centers in Europe affects child outcomes. The European studies are quite recent and limited in numbers, and our results show a significant positive effect of PD on child outcomes with an overall effect size of 0.35 (with a 95% confidence interval from 0.20 to 0.51). The magnitude is slightly smaller than corresponding results based on US studies, but indicates a general positive effect of PD on child outcomes.  相似文献

Becoming an Ironman triathlete. Extreme exercise,gender equality and the family puzzle     

Jesper Andreasson  Thomas Johansson  Tom Danielsson 《Sport in Society》2018,21(9):1351-1363

Departing from a qualitative research approach, this article focuses on Swedish amateur Ironman triathletes and their family life. The purpose of the paper is to investigate how an elite amateur lifestyle is upheld and balanced with the demands of a sustainable family and social life. The results indicate that the process of becoming and staying an Ironman creates tensions in intimate relationships, making it hard to bring the family life puzzle together. Although the participants interviewed often talk about family life in terms of sharing things fairly equally, in terms of gender equity and involved parenthood, this seemingly is not always an easy ideal to fulfil in practice. On a broader cultural level, these findings can thus be contextualized in relation to discourses associated with the gendering of families and functions, and, of course, the gender of sport and performance.  相似文献
