Television news is government news in Taiwan patterns of television news sources selection and presentation

Based on a content analysis of evening newscasts by the three television stations in Taiwan, this study examines the patterns of news sources selection and presentation in television news. The results of this study show that television news relies heavily on government officials who are primarily middle‐aged men in executive positions located in the capital city of Taipei. These findings suggest that the central government officials in Taipei appear to be the primary definers of social reality. TV news portrays only a very limited view of the society. In conclusion, this study suggests that with the management and content tightly controlled by the state, Taiwan's television news consists primarily of official rituals.     

Developing a Framework for Analyzing Definitions: A study of The Feynman Lectures

One important purpose of a definition is to explain the meaning of a word. Any problems associated with a definition may impede students' learning. However, research studies on the definitional problems from the perspective of physics education are limited. Physics educators may not be aware of the nature and extent of definitional problems. As an example, The Feynman Lectures of Physics suggest that there are at least four problems of definition: precision, circularity, context and completeness in knowledge. Feynman had the tendency of mentioning the words ‘define’ and ‘definition’ and discussing the problems of definition: they can be insightful, or challenge the conventional, preconceived notions of many physical concepts. One benefit of this study is that a framework can be developed to improve statements of definitions. This framework may guide educators or students to analyze the knowledge that is embedded in a definition. In the future, the learning of definition need not be content-oriented, but problem-based instead, with the help of definitional problems. Therefore, the use of these problems of definition in lessons can be an interesting area for future physics education research. Furthermore, we should be cognizant of inadequacies or inaccuracies in definition that may result in alternative conceptions.     

Differences in the Scientific Epistemological Views of Undergraduate Students

The purpose of this study was to examine whether science and non‐science major students have different scientific epistemological views (SEVs). A multidimensional instrument previously developed by the authors was used to assess differences in college students’ SEV of various aspects. A total of 220 freshmen (42% science and 58% non‐science majors) attending two public universities participated in this investigation. Results indicated that the science majors have less sophisticated beliefs in the theory‐laden and cultural‐dependent aspects of science than non‐science majors. Analysis of variance results further revealed significant differences in SEV dimensions among the three major fields: non‐science, pure science, and science education. Science education students gained the lowest scores on the entire scale among the groups. Findings of this study imply that science major (including science education) students might be involved longer in such an epistemic environment that described scientific knowledge as objective and universal. It is also possible that beliefs about certainty and objectivity lead these students to select science as their major field. Implications for future research and science teacher education are discussed.     

The off-break and “doosra”: Kinematic variations of elite and sub-elite bowlers in creating ball spin in cricket bowling

This study sought to identify kinematic differences in finger-spin bowling actions required to generate variations in ball speed and spin between different playing groups. A 12-camera Vicon system recorded the off-spin bowling actions of six elite and 13 high-performance spin bowlers, and the “doosra” actions of four elite and two high-performance players. Forearm abduction and fixed elbow flexion in the bowling arm were higher for the elite players compared with the high-performance players. The elite bowlers when compared with the high-performance players delivered the off-break at a statistically significant higher velocity (75.1 and 67.1 km/hr respectively) and with a higher level of spin (26.7 and 22.2 rev/s respectively). Large effect sizes were seen between ball rotation, pelvic and shoulder alignment rotations in the transverse plane. Elbow extension was larger for elite bowlers over the period upper arm horizontal to ball release. Compared to the off-break, larger ranges of shoulder horizontal rotation, elbow and wrist extension were evident for the “doosra”. Furthermore, the “doosra” was bowled with a significantly longer stride length and lower ball release height. Although not significantly different, moderate to high effect size differences were recorded for pelvis rotation, elbow extension and elbow rotation ranges of motion.     

Effects of Different Exercise Intensities With Isoenergetic Expenditures on C-Reactive Protein and Blood Lipid Levels

We investigated the effects of different exercise intensities on C-reactive protein (CRP), and whether changes in CRP levels correlated with blood lipid levels. Ten men exercised at 25%, 65%, and 85% of their maximum oxygen consumption rates. Participants' blood was analyzed for CRP and blood lipid levels before and after the exercise sessions. Although there was an intensity effect for postexercise high-density lipoprotein levels, there were no significant differences or correlations for postexercise CRP levels or between CRP and lipid levels across the three exercise intensities. In an acute aerobic bout model with isoenergetic expenditures, CRP was not affected by the exercise intensity. Additionally, changes in blood lipid levels might not have been connected to CRP levels for physically fit participants.

Taiwanese Students in Malaysia and Interculturality: When National Identities Take Primacy over Individualities

Abstract Using a liquid approach, the authors analyze the intercultural discourse of Taiwanese students who had taken part in a short term exchange program with a Malaysian university. The four participants were graduating in Mandarin Chinese in their home institution and were following a Chinese program in multilingual Malaysia. Data were collected through focus groups held in Mandarin Chinese and focused on their experience in the host country. The authors analyze how participants talk about themselves, Malaysians, and their adaptation to the host country. The processes of essentialization and othering that occur and put in contrast the host and the home contexts are similar to those held in Asia-to-Europe mobility and very far from an “interculturality without culture” (Dervin, 2010). If we focus on the construction of discourses, this Asia-to-Asia mobility forces us to relativize the opposition of cultures as an explanation for difficulties encountered by mobile students.     

The understanding and development of cycling aerodynamics

In elite cycling the resistive force is dominated by aerodynamics. Be it on the roads or in the velodrome, the sport has many examples where aerodynamics has won and lost races. Since the invention of the bicycle, engineers have strived to improve performance, often by reducing aerodynamic drag. Over the last 50 years a number of authors have presented their efforts in journals, books and magazines. This review summarises the publications that show the continued development in the aerodynamics of cycling. The review concludes by examining the shortcomings of the current understanding and making suggestions for future research and development.
