Effects of the “Gangnam Style Syndrome” on the South Korean stock market     

Hyun Joung Jin  Jang-Chul Kim 《Journal of Cultural Economics》2018,42(1):139-161

This study attempts to answer two questions. First, can a single cultural event impact the stock prices of a wide range of companies and sectors? Second, was the positive stock market response in the information technology (IT) sector as well as performing arts sector significant? To answer these questions, we examine whether a hit pop single, “Gangnam Style” by Park Jae-Sang in 2012, affected related sectors of the Korean stock market and whether market reactions went beyond the stock price of the singer’s agency to affect those of other firms. We use an event study approach. The results show two notable empirical findings. First, although the findings indicating abnormal returns and cumulative abnormal returns appear mixed, the overall results imply that the unprecedented worldwide hit single by the South Korean singer positively affected the Recreation & Culture and Digital Content sectors. In other words, the market interpreted the event as good news, with shareholders expecting positive effects on the related sectors. Second, a positive stock market response was observed in the IT sector as well.  相似文献   

Towards truly inclusive science education: a case study of successful curriculum innovation in a special school     

Jane Essex 《Support for Learning》2020,35(4):542-558

The paper provides a first person account of participant evaluation research of curriculum innovation in a school serving students with profound learning difficulties. It describes how the aspirations of the school leadership team to introduce science, combined with advisory support, overcame the initial anxiety of teaching staff about teaching an unfamiliar subject. The staff position was transformed and they gave a very positive evaluation of their experiences of teaching science, due to the impact of the subject on their students. The introduction of a distinct and inclusive model of science into the curriculum was ultimately found to have significant benefits for both students and staff.  相似文献   

Modern dietary guidelines for healthy pregnancy; maximising maternal and foetal outcomes and limiting excessive gestational weight gain     

Kirsty Jayne Elliott-Sale  Ashley Graham  Stephanie Jane Hanley  Sherry Blumenthal  Craig Sale 《European Journal of Sport Science》2019,19(1):62-70

Abstract

Maternal dietary habits influence maternal and foetal health, representing a pathway for intervention to maximise pregnancy outcomes. Advice on energy intake is provided on a trimester basis, with no additional calories required in the first trimester and an additional 340?kcal?d^?1 and 452?kcal?d^?1 needed for the second and third trimesters. Energy intake depends on pre-gravid body mass index (BMI); underweight women are recommended an increase of 150, 200 and 300?kcal?d^?1 during the first, second and third trimester, normal weight women an increase of 0, 350 and 500?kcal?d^?1 and obese women an increase of 0, 450 and 350?kcal?day^?1. The recommendations for carbohydrate and protein intake are 175?g?d^?1 and 0.88–1.1?g?kgBM?d^?1, with no change to fat intake. The number of pre-gravid obese women is rising; therefore, we need to regulate weight in women of childbearing age and limit gestational weight gain to within the recommended ranges [overweight women 6.8–11.3?kg and obese women 5.0–9.1?kg]. This can be achieved using nutritional interventions, as dietary changes have been shown to help with gestational weight management. As pregnancy has been identified as a risk factor for the development of obesity, normal weight women should gain 11.5–16.0?kg during pregnancy. While some research has shown that dietary interventions help to regulate gestational weight gain and promote postpartum weight loss to some extent, future research is needed to provide safe and effective guidelines to maximise these effects, while benefitting maternal and foetal health.  相似文献   

Engagement with news on Twitter: insights from Australia and Korea     

Robert Ackland  Mathieu O’Neil  Sora Park 《亚洲交流杂志》2019,29(3):235-251

ABSTRACT

This study examines the patterns of news engagement among news consumers with different political affiliation and cultural background. We use computational methods and data from Twitter in a cross-country comparison of engagement with six online news sources in Australia and South Korea. For our analysis, we used a subset of Twitter users who retweeted at least one political story during the period of collection, and for whom we were able to predict political affiliation using correspondence analysis and data on Twitter follower ties to politicians. We find that right-wing Australian retweeters are more intense in their news engagement, compared with their left-wing counterparts, whereas in South Korea it was the opposite. Australian right-wing political retweeters have more diverse information sources, while there was no difference in information diversity between the right and left in South Korea. We discuss how the political situation in South Korea at the time of data collection may have affected our analysis. We emphasise the methodological contributions of our research and its connection to on-going research into the behavioural foundations of ‘filter bubbles’.  相似文献   

Embodied inter-referencing: encounters with and among “Asian” students in the Australian classroom     

Jane Chi Hyun Park 《Inter-Asia Cultural Studies》2019,20(2):271-289

ABSTRACT

This essay examines the pedagogical practice of referencing my experiences as a transnational Korean American woman in the classroom and considers how it opens up space for domestic and international students of East, Southeast, and South Asian backgrounds to reflect on their different identities, histories, and cultures. In particular, it focuses on how this practice enables Asian students to share their experiences of and insights about racial difference, racism, and whiteness in Australia and other parts of the world. Building on the concept of Asian “inter-referencing” from Chua Beng Huat (2015), I coin the term “embodied inter-referencing” to describe the strategic ways I use autobiographical narrative to create an inclusive, interactive, and mutually respectful learning space. I centre here on how some Asian students respond to this strategy by telling their own stories and in the process, create transnational, diasporic, and inter-Asian affective communities inside and outside the classroom.  相似文献   

The kinematic differences between accurate and inaccurate squash forehand drives for athletes of different skill levels

ABSTRACT

To maintain the accuracy of squash shots under varying conditions, such as the oncoming ball’s velocity and trajectory, players must adjust their technique. Although differences in technique between skilled and less-skilled players have been studied, it is not yet understood how players vary their technique in a functional manner to maintain accuracy under varying conditions. This study compared 3-dimensional joint and racket kinematics and their variability between accurate and inaccurate squash forehand drives of 9 highly skilled and 9 less-skilled male athletes. During inaccurate shots, less-skilled players hit the ball with a more open racket, demonstrating a difference in this task-relevant parameter. No joint kinematic differences were found for accuracy for either group. Coordinated joint rotations at the elbow and wrist both displayed a “zeroing-in” effect, whereby movement variability was reduced from the initiation of propulsive joint rotation to a higher consistency at ball-impact; potentially highlighting the “functionality” of the variability prior to the impact that enabled consistent task-relevant parameters (racket orientation and velocity) under varying conditions. Further, highly skilled players demonstrated greater consistency of task-relevant parameters at impact than less-skilled players. These findings highlight the superior ability of highly skilled players to adjust their technique to achieve consistent task-relevant parameters and a successful shot.  相似文献

美国与日本电信产业政策变化的比较分析--由管制产业向自由竞争产业的转变     

池建新  朱庆华 《情报杂志》2006,25(2):115-117

大多数国家的电信产业历来是在天然垄断理论下,由政府来进行电信基础设施的建设和提供相关服务的.但是,电信企业又会因其国有体制或处于垄断地位的原因而出现经营效率低下、劳务成本过高、提供的服务质量差的结果.因此,对电信部门进行民营化改革,并促进该领域的自由竞争成为各国电信产业政策的取向.通过对美国、日本电信产业政策变化的研究和比较,揭示了美、日在电信领域产生巨大差距的根本原因.  相似文献
