Webcasting Business Models of Clicks-and-Bricks and Pure-Play Media: A Comparative Study of Leading Webcasters in South Korea and the United States     

Louisa Ha  Richard Ganahl 《媒体管理杂志》2013,15(1-2):74-87

This article identifies the business models of leading Webcasters in the United States and South Korea and proposes a cross-cultural framework to analyze the determinants of business models. The file transmission methods, content strategies, and revenue sources of clicks-and-bricks and pure-play Webcasters were compared in the study. After analyzing the business practices of 48 leading Webcasters--using a content analysis of their sites--we found that the content aggregator model and the branded content model are the 2 most commonly used business models of leading Webcasters in the United States and South Korea. Although clicks-and-bricks and pure-play Webcasters in both countries have a similar reliance on advertising as their major source of revenue, they employ different content strategies to their own media's advantages. Korean Webcasters are more likely to use pay-per-view as a revenue source than U.S. Webcasters.  相似文献

Feeling of certainty: Uncovering a missing link between knowledge and acceptance of evolution   总被引：1，自引：0，他引：1  

Minsu Ha  David L. Haury  Ross H. Nehm 《科学教学研究杂志》2012,49(1):95-121

We propose a new model of the factors influencing acceptance of evolutionary theory that highlights a novel variable unexplored in previous studies: the feeling of certainty (FOC). The model is grounded in an emerging understanding of brain function that acknowledges the contributions of intuitive cognitions in making decisions, such as whether or not to accept a particular theoretical explanation of events. Specifically, we examine the relationships among religious identity, level of education, level of knowledge, FOC, and level of evolutionary acceptance to test whether our proposed model accurately predicts hypothesized pathways. We employ widely used measures—the CINS, MATE, and ORI—in addition to new variables in multiple regression and path analyses in order to test the interrelationships among FOC and acceptance of evolutionary theory. We explore these relationships using a sample of 124 pre‐service biology teachers found to display comparable knowledge and belief levels as reported in previous studies on this topic. All of our hypothesis tests corroborated the idea that FOC plays a moderating role in relationships among evolutionary knowledge and beliefs. Educational research into acceptance of evolutionary theory will likely benefit from increased attention to non‐conscious intuitive cognitions that give rise to feeling of knowing or certainty. © 2011 Wiley Periodicals, Inc.

Chinese pre-service biology teachers’ evolutionary knowledge,reasoning patterns,and acceptance levels     

Minsu Ha  Xin Wei  Jian Wang  Dan Hou  Ross H. Nehm 《International Journal of Science Education》2019,41(5):628-651

The goal of our study was to examine a large (>400), cross-sectional sample of Chinese pre-service biology teachers (PBTs) in order to document their evolution acceptance levels, evolution knowledge, and evolutionary reasoning patterns. This approach was taken in order to better understand the degree to which particular evolutionary reasoning difficulties exist independent of religious worldviews. The sample included (1) 160 PBTs tasked with completing four items from the ACORNS instrument, (2) 320 PBTs who completed the CINS and MATE instruments, and (3) 32 teachers who completed semi-structured clinical interviews using four ACORNS items. Findings from these samples revealed that Chinese PBTs’ knowledge (CINS) and acceptance (MATE) were equivalent with teachers’ scores from other countries, whereas performance on explanation tasks was lower. Scores from the CINS, MATE, and ACORNS did not reveal any significant improvements through the four-year teacher education programme. Although a large body of work has shown the important roles that religious affiliation and religiosity can play in evolutionary understanding and acceptance, our findings demonstrate that many evolutionary reasoning difficulties extend beyond religious factors, and add to a growing body of work showing that religiosity does not adequately account for PBTs’ moderate evolution acceptance.  相似文献   

Collaborative learning practices: teacher and student perceived obstacles to effective student collaboration     

Ha Le  Jeroen Janssen  Theo Wubbels 《Cambridge Journal of Education》2018,48(1):103-122

While the educational literature mentions several obstacles affecting the effectiveness of collaborative learning (CL), they have often been investigated through the perceptions of only one actor, either teachers or students. Therefore, some sources of obstacles that teachers and students encounter may not have been revealed. In this study, 19 teachers and 23 students in different disciplines at a pre-service teacher education faculty at a university in Vietnam were interviewed. In total, 47% of the teachers taught science subjects and 53% taught social subjects; 35% of the students majored in science subjects, 57% in social subjects, and 8% in primary education. With regard to study cohorts, 22% of the students were in the first and second year while 78% were in the third and fourth year of their four-year bachelor’s programme. These programmes produce qualified teachers for primary and secondary schools nationwide. Based on grounded theory analysis, four common obstacles to collaboration were identified: students’ lack of collaborative skills, free-riding, competence status, and friendship. Furthermore, the results showed three interrelated antecedents that contribute to these obstacles. Central to the antecedents is the strong focus of the teachers on the cognitive aspects of CL, which led the participating teachers to neglect the collaborative aspects of CL. These antecedents were demonstrated in the ways teachers set CL goals, provided instruction, and assessed student collaboration. This study may be useful for educators, designers, and researchers to foster the quality of student collaboration.  相似文献

Quasi-experimental evidence of academic peer effects at an Elite University in People’s Republic of China     

Ha  Wei 《Asia Pacific Education Review》2016,17(4):703-718

This paper examines the effects of roommates on students’ academic outcomes exploiting the randomized roommate assignment system at a selective Chinese university. Unlike earlier studies that could not measure students’ academic quality precisely, this paper makes two important improvements in measuring their English proficiency and overall academic aptitude. I find that randomly assigned roommates’ average pre-treatment academic abilities are not significant determinants of students’ academic performance across a number of different specifications. However, students are significantly influenced by roommates’ decisions in terms of the number of elective course credits taken and the choice of major.

Association between moderately oxidized low-density lipoprotein and high-density lipoprotein particle subclass distribution in hemodialyzed and post-renal transplant patients     

Kimak E  Hałabiś M  Baranowicz-Gąszczyk I  Solski J  Książek A 《Journal of Zhejiang University. Science. B》2011,12(5):365-371

Disturbances in the metabolism of lipoprotein profiles and oxidative stress in hemodialyzed (HD) and post-renal transplant (Tx) patients are proatherogenic, but elevated concentrations of plasma high-density lipoprotein (HDL) reduce the risk of cardiovascular disease. We investigated the concentrations of lipid, lipoprotein, HDL particle, oxidized low-density lipoprotein (ox-LDL) and anti-ox-LDL, and paraoxonase-1 (PON-1) activity in HD (n=33) and Tx (n=71) patients who were non-smokers without active inflammatory disease, liver disease, diabetes, or malignancy. HD patients had moderate hypertriglyceridemia, normocholesterolemia, low HDL-C, apolipoprotein A-I (apoA-I) and HDL particle concentrations as well as PON-1 activity, and increased ox-LDL and anti-ox-LDL levels. Tx patients had hypertriglyceridemia, hypercholesterolemia, moderately decreased HDL-C and HDL particle concentrations and PON-1 activity, and moderately increased ox-LDL and anti-ox-LDL levels as compared to the reference, but ox-LDL and anti-ox-LDL levels and PON-1 activity were more disturbed in HD patients. However, in both patient groups, lipid and lipoprotein ratios (total cholesterol (TC)/HDL-C, LDL-C/HDL-C, triglyceride (TG)/HDL-C, HDL-C/non-HDL-C, apoA-I/apoB, HDL-C/apoA-I, TG/HDL) were atherogenic. The Spearman’s rank coefficient test showed that the concentration of ox-LDL correlated positively with HDL particle level (R=0.363, P=0.004), and negatively with TC (R=−0.306, P=0.012), LDL-C (R=−0.283, P=0.020), and non-HDL-C (R=−0.263, P=0.030) levels in Tx patients. Multiple stepwise forward regression analysis in Tx patients demonstrated that ox-LDL concentration, as an independent variable, was associated significantly positively with HDL particle level. The results indicated that ox-LDL and decreased PON-1 activity in Tx patients may give rise to more mildly-oxidized HDLs, which are less stable, easily undergo metabolic remodeling, generate a greater number of smaller pre-β-HDL particles, and thus accelerate reverse cholesterol transport, which may be beneficial for Tx patients. Further studies are necessary to confirm this.  相似文献
