The economics of scholarly journals: a case study on a society‐published journal     

Louisa Ha 《Learned Publishing》2003,16(3):193-199

This article re‐examines the economics of publishing scholarly journals and illustrates the dilemma of publisher identity and publication format with a case study of the Association for Education in Journalism and Mass Communication's Media Management and Economics division. The study investigates the perceived interest and demand for a society‐published journal for the field of media management and economics and the preferred format for that journal – print or online. Results showed a divided opinion on the support of a society‐published journal and no consideration of the benefits or harms of journal publishing to the society. The print journal, though a desirable format for authors, is deemed uneconomical. The online journal is viewed as a feasible publication outlet, but its status as a prestigious journal is doubtful. Applications of scholarly journal publishing and economic models to the case are discussed.  相似文献   

The effects of gain versus loss framing and issue involvement on publics’ responses to nuclear energy messages in South Korea     

Hyo Jung Kim 《亚洲交流杂志》2018,28(5):541-558

This study investigates how the public’s perceptions of nuclear power, one of the modern technologies at the center of public debate on risk issues, are influenced by gain versus loss framing in the volatile context of nuclear energy applications in South Korea. Drawing upon prospect theory as its conceptual framework, this experiment using 566 adult participants found that loss-framed messages (i.e. emphasizing the negative outcomes of not using nuclear power) were more effective in increasing participants’ message credibility perceptions as compared to gain-framed messages (i.e. emphasizing the positive outcomes of using nuclear power). Additionally, the results found issue involvement to be a significant moderator of the framing effect, by demonstrating that the advantage of loss framing was stronger for participants who were highly involved in nuclear energy issue, as compared to those who were less involved in the issue. The theoretical and practical implications of these findings are discussed.  相似文献   

Estimating fat-free mass in elite-level male rowers: a four-compartment model validation of laboratory and field methods     

Kristina L. Kendall  David H. Fukuda  Parker N. Hyde  Abbie E. Smith-Ryan  Jordon R. Moon  Jeffrey R. Stout 《Journal of sports sciences》2017,35(7):624-633

The purpose of this study was to investigate the accuracy of fat-free mass (FFM) estimates from two-compartment (2C) models including air displacement plethysmography (ADP), ultrasound (US), near-infrared interactance (NIR), and the Jackson and Pollock skinfold equation (SKF) against a criterion four-compartment (4C) model in elite male rowers. METHODS: Twenty-three elite-level male rowers (mean± SD; age 24.6 ± 2.2 years; stature: 191.4 ± 7.2 cm; mass: 87.2 ± 11.2 kg) participated in this investigation. All body composition assessments were performed on the same day in random order, except for hydrostatic weighing (HW), which was measured last. FFM was evaluated using a 4C model, which included total body water from bioimpedance spectroscopy, body volume from HW, and total body bone mineral via dual-energy X-ray absorptiometry. The major findings of the study were that the 2C models evaluated overestimated FFM and should be considered with caution for the assessment of FFM in elite male rowers. Future studies should use multiple-compartment models, with measurement of TBW and bone mineral content, for the estimation of FFM.  相似文献

Perceived Message Effectiveness Predicts Information-Seeking Behavior     

James Price Dillard  Yerheen Ha 《Communication Research Reports》2016,33(4):356-362

This study examined whether perceived message effectiveness (PE) predicted information-seeking behavior in the topical domain of colon cancer. Participants (N = 277) viewed one of three video messages (news, testimonial, and animation) that advocated screening for colon cancer. Information-seeking behavior was operationalized as reading time for a subsequent message about colon cancer. The proposed mediation model successfully reproduced the pattern of data, thereby providing evidence that PE predicts behavior via intention.  相似文献   

TASK ANALYSIS: BULIDING MODELS OF CHANGE PROCESSES IN GIFTED EDUCATION     

Sidney M. Moon  Fred P. Piercy 《High Ability Studies》1992,3(2):181-189

Researchers in the field of gifted education are becoming increasingly aware that a variety of research approaches can make contributions to research on giftedness. This paper describes task analysis, a research methodology derived from counseling process research. Task analysis appears to be a useful research approach for building theoretical models of how therapeutic and educational interventions can facilitate positive changes in gifted children. The paper traces the historical development of task analysis methodology, describes the steps involved in conducting a rational‐empirical task analysis of change processes, and provides an example of how task analysis methodology might be applied to investigations of change processes in the field of gifted education.  相似文献

Students’ perceptions of classroom instructional environments in the context of ‘Universal Design for Learning’     

Michael M. Abell  Eunjoo Jung  Matthew Taylor 《Learning Environments Research》2011,14(2):171-185

Using a sample of 867 students in Grades 5–12, the present study investigated whether students’ perceptions toward the instructional environment in classrooms that employed Universal Design for Learning differed by school grade level and teacher gender. High-school students in the study showed higher perception scores than upper-elementary or middle-school students in the personalisation and participation aspect of the classroom environment. The results for teacher gender indicated that students in the study perceived a more personalised classroom environment with female teachers than with male teachers. Policy implications and methodological considerations are provided for future study.  相似文献   

Skills for Independence for Children with Cerebral Palsy: a comparative longitudinal study     

Jane Jung‐Ae Hur 《International Journal of Disability, Development & Education》1997,44(3):263-274

Thirty‐six children with cerebral palsy, aged 3.5 to 4.5 years were compared on their skills for independence. Of the 36 boys and girls, 19 children were enrolled in a Conductive Education Program in Birmingham and 17 were enrolled in British special education programs in the Greater Manchester area. Skills for independence were measured with the Vineland Adaptive Behavior Scales via teachers’ responses, once a year on three occasions. Parents were interviewed using the Developmental Profile 2, once a year on three occasions. The results of two‐way ANOVA with one repeated measure on both teachers’ and parents’ responses indicate that there was no significant difference between the two groups in their skills for independence. However, both groups performed significantly better as they were getting older. Despite the strong emphasis on independence in Conductive Education, the children's level of independence was no different from their counterparts. Thus, the claim for the effectiveness of Conductive Education is not supported by the study.  相似文献
