Researcher Study Thyself: AERA Participants' Speaking Times and Turns by Gender     

Lynda R. Wiest  Tammy V. Abernathy  Kathryn M. Obenchain  Elza M. Major 《Equity & Excellence in Education》2013,46(4):313-323

This research compares speaking times and turns of female and male presenters and audience members at the 2000 Annual Meeting of the American Educational Research Association (AERA). In their presentations, males spoke longer than females, but the differences were not statistically significant. They spoke significantly longer than females, however, when posing questions or comments during open discussions, and they made a significantly greater number of responses to these questions and comments. Some chairs were inconsistent in monitoring allotted speaking times. Females' participation was lower in less-structured situations, such as open discussions and co-presented papers, than in settings with greater structure.  相似文献   

The effects of an unanticipated side-cut on lower extremity kinematics and ground reaction forces during a drop landing     

Jae P. Yom  Tane Owens  Scott Arnett  Justin Beebe  Veronica Son 《Sports biomechanics / International Society of Biomechanics in Sports》2019,18(4):414-425

Unanticipated direction to cut after landing may alter the lower extremity landing biomechanics when performing landing motions. These alterations may potentially increase the risk of ACL injury. The purpose of this study was to determine if an unanticipated side-cut affects lower extremity landing biomechanics in females. Eighteen recreational female athletes participated in two blocks of testing: the first block of testing consisted of three acceptable trials of anticipated dominant limb and non-dominant limb 45-degree diagonal cutting after landing, which were performed in a counterbalanced order. The second block of testing consisted of three acceptable trials of unanticipated dominant limb and non-dominant limb diagonal cutting after landing. Data analysis mainly focused on the dominant limb landing biomechanics. Unanticipated side-cut landing, compared (paired t-test, p < 0.05) to the anticipated landings, resulted in less hip abduction and tibial internal rotation angle at initial contact (IC) and a lower maximum ankle inversion angle and a greater maximum knee abduction angle, and knee and hip displacement. Also, greater posterior GRF and a longer time to peak medial GRF were exhibited. These outcomes indicate that athletes may adapt their landing mechanics to land unsafely when encountering an unanticipated event.  相似文献   

Influence of team identification,game outcome,and game process on sport consumers’ happiness     

Wonseok Jang  Daniel L. Wann  Yong Jae Ko 《Sport Management Review》2018,21(1):63-71

The purpose of the study is to examine the relative effects of game process (i.e., boring versus exciting) and outcome (i.e., losing versus winning) on sport consumers’ happiness depending on their level of team identification. The authors investigated how sport consumers’ levels of happiness are different after recalling (Study 1) and imagining (Study 2) a game when the positivity of the game process and the outcome contradict each other. Results indicate that sport consumers with high team identification exhibited greater degrees of happiness after recalling and imagining a boring win game compared to an exciting loss game. Meanwhile, sport consumers with low team identification exhibited similar degrees of happiness between a boring win game and an exciting loss game.  相似文献   

When Power is the Limit: The Image of the Professor in Selected Fiction     

Claire H. Major 《Innovative Higher Education》1998,23(2):127-143

The professor has appeared as a fictional character since the middle ages, and several professorial images may be found in academic fiction. An analysis of fictional images reveals that authors most often depict professors who have no ambitions to gain power, whether economic, personal, political, or philosophical, as estimable characters; but authors condemn professor characters who attempt to exert power in order to gain money, relationships, position, or knowledge.  相似文献   

For whom the bell tolls: globalisation,social class and South Korea's international schools     

Jae Jung Song 《Globalisation, Societies & Education》2013,11(1):136-159

This article discusses how in South Korea, English-medium international schools, initially established to educate foreign residents, have recently transformed themselves into private providers of global education for South Koreans. The article explains the social, economic and political circumstances under which the South Korean government has allowed this transformation to take place in response to the forces of globalisation as well as to South Korean elites' educational demand. The article argues that English-medium international schools are elite-class reproducing institutions. The role of English, one of the major imperatives of global capitalism, will also be discussed, as this language has been impinging on South Korea's education and labour market.  相似文献   

Forthcoming Conference     

Seoung‐Hey Paik  Hyo‐Nam Kim  Boo‐Kyoung Cho  Jae‐Won Park 《International Journal of Science Education》2013,35(2):207-208

This study investigates the various conceptions held by K‐8th Korean grade students regarding the ‘changes of state’ and the ‘conditions for changes of state’. The study used a sample of five kindergarteners, five secondgrade students, five fourth‐grade students, five sixth‐grade students, and five eighth‐grade students. The 25 students attend schools in a rural district of South Korea. Some activities that involved a change in the state of water, including condensation, solidification, and melting, were chosen from K‐8th grade science textbooks and attempted by the students. Subsequently, we conducted interviews with the students. While most kindergarteners and second‐grade students were able to perceive the phenomena involving changes of state, they were unable to express conceptions related to the changes of state and the conditions under which the state the changes. The upper‐grade students, on the other hand, had some conception of the invisible gas state. Most of these students held conceptions about the boiling water's change of state from liquid to gas, but few of them held conceptions about the changes of state involving condensation. Most students understood heat and temperature as conditions of the changes of state, but only applied the heat concept to situations involving rising temperatures. In situations involving cooling, students applied the temperature concept. The younger students understood the concept of heat without understanding the concept of temperature.  相似文献   

Decreasing the Proportion of Self-Control Trials During the Acquisition Period Does Not Compromise the Learning Advantages in a Self-Controlled Context     

Jae T. Patterson  Michael Carter  Elizabeth Sanli 《Research quarterly for exercise and sport》2013,84(4):624-633

The present experiment examined the learning effects of participants self-controlling their receipt of knowledge of results (KR) on all or half of their acquisition trials (50%). For participants who were provided 50% self-control, the first half of their acquisition period consisted of receiving KR on all trials, or according to a faded-KR schedule. Participants practiced a sequential timing task. The results showed that independent of practice condition, participants who self-controlled their KR during the acquisition period demonstrated superior performance compared to the respective yoked conditions in the retention and transfer portion of the experiment. These results extend previous research by suggesting that decreasing the proportion of self-control trials does not compromise learning in a self-controlled context.  相似文献   

Desalination characteristics for ceramics excavated from Taean shipwreck,Korea     

Sungyoon Jang  Byeongjik Nam  Daewoo Park  Hyoyun Kim  Chan Hee Lee  Jae Eun Yu 《Journal of Cultural Heritage》2013,14(3):229-237

The ceramic artefacts, excavated from ancient shipwrecks, are generally saturated with soluble salts, mainly NaCl, within the porous structure of ceramics. The salinity contents typically exhibit ionic and osmotic pressures to the ceramic microstructures, thus causing significant damages to the integrity of ceramic artefacts. While the utilisation of aqueous soaking methods is commonly accepted for effective desalination processes of ceramics, the relationships between the structural characteristics of ceramics and the desalination efficiency have not been demonstrated. In this study, we examined the desalination processes of various ceramics excavated from the Taean shipwrecks in South Korea to identify major controlling factors for the desalination processes. Our results indicated that the physical properties of ceramics including the water absorption and the pore size distribution greatly influence on the desalination process time and efficiency. It is also found that the surface condition of ceramic samples such as microstructural cracks on the glaze layer is a crucial component of the desalination characteristics. Nevertheless, the small residue of salts such as NaCl crystals were found in the microstructures of some ceramics after prolonged desalination periods. Therefore, it is important to control the humidity and temperature in the conservation environment for desalinated ceramic artefacts even after desalination.  相似文献   

The effect of site quality on repurchase intention in Internet shopping through mediating variables: The case of university students in South Korea     

Jae Ik Shin  Ki Han Chung  Jae Sin Oh  Chang Won Lee 《International Journal of Information Management》2013

We performed a study to determine the influence that site quality has on repurchase intention of Internet shopping through customer satisfaction, customer trust, and customer commitment. Appropriate measures were developed and tested on 230 university students of Gyeongnam province in South Korea with a cross-sectional questionnaire survey. The results of the empirical analysis confirmed that site quality can be conceptualized as a composite of six dimensions of shopping convenience, site design, information usefulness, transaction security, payment system, and customer communication. Second, site quality positively affected customer satisfaction and customer trust, but did not affect customer commitment and repurchase intention. Third, site quality can affect repurchase intention by enhancing or attenuating customer satisfaction, customer trust, and customer commitment in online transaction situation. The mediating effect of customer satisfaction, customer trust, and customer commitment between site quality and repurchase intention is identified. Fourth, site quality indirectly affected customer commitment through customer satisfaction. Customer satisfaction indirectly affected repurchase intention through customer trust and customer commitment. Thus, it is found that site quality can be a very important factor to enhance repurchase intention in the customer perspective.  相似文献   

Thematic Approach to Theoretical Speculations in the Field of Educational Administration     

Jae Park 《Educational Philosophy and Theory》2015,47(4):359-371

Abstract

The purpose of this article is a critical reflection on the field of educational administration and its varied and often conflicting epistemologies. It is argued that the field of educational administration is a community of diverse epistemologies. Although epistemological heterogeneity has been persistently vilified by both theorists and pragmatists with their own discursive agendas, it is this precise environment of critical dialogue and diversity that is conducive to new frontiers in the field. A phenomenology of recognition is thus presented as a showcase for the possibility of approaching and expanding the field topically rather than treatise-like generalizations at the macro level, which are mostly dated discussions on philosophy of science. The principal value of the article is showing alternative pathways—not limited to the discussions about theory of recognition—to new frontiers in educational administration by demonstrating the possibility of thematic theory developments in the field and defending the diversity of existing epistemologies in the field as an asset rather than a liability for further development in the field.  相似文献
