Extrovert and Lonely Individuals’ Social TV Viewing Experiences: A Mediating and Moderating Role of Social Presence     

Jihyun Kim  Sanguk Lee 《Mass Communication and Society》2018,21(1):50-70

Social TV viewing is generally understood as a simultaneous act of watching TV and engaging in communication about the TV program with other TV viewers connected online. In response to the increasing popularity of this new TV viewing practice, the current study examined how individuals’ extrovert personality and loneliness influence social TV viewing experiences through the theoretical notion of social presence. An online survey was completed by 330 individuals. Results demonstrated that extrovert personality positively influenced social TV viewing experiences; it is important to note that this relationship was mediated by social presence. Loneliness itself was negatively related to social TV viewing experiences; however, this relationship was moderated by social presence. Specifically, when lonely people felt strong social presence, they enjoyed social TV viewing experiences. The findings provide theoretical implications for social TV research, the dynamic role of social presence, social enhancement model, and social compensation model.  相似文献

The aim of this cross-sectional study was to compare bone mass in young female athletes playing ball games on different types of playing surfaces. About 120 girls, 9–13 years of age (10.6 ± 1.5 years old Tanner I–III) were recruited and divided into prepubertal and pubertal groups. The sample represented 3 groups of athletes: soccer (N = 40), basketball (N = 40), and handball (N = 40); and 6 different playing surfaces (soccer – ground, soccer – artificial turf, basketball – synthetic, basketball – parquet, handball – synthetic, and handball – smooth concrete). Total and regional body composition (bone mass, fat mass, and lean mass) were measured by dual-energy X-ray absorptiometry (DXA). The mechanical properties of the surfaces (force reduction, vertical deformation, and energy return) were measured with the Advanced Artificial Athlete (Triple A) method. The degree of sexual development was determined using Tanner test. The pubertal group showed that soccer players on the ground, basketball players on synthetic, and handball players on smooth concrete had higher values of bone mineral content (BMC) and bone mineral density (BMD) (P < 0.05) than the soccer players on the artificial turf, basketball players on parquet, and handball players on synthetic. In conclusion, a hard playing surface, with less vertical deformation and force reduction, and greater energy return, is associated with higher levels of BMD and BMC in growing girls, regardless of the sport they practice.  相似文献   

New paint,new challenges: Conservation of Roy Lichtenstein's outdoor sculpture House I     

Nani Lew  Jihyun Choi 《文物保护研究》2016,61(3):114-119

This paper deals with the conservation of Roy Lichtenstein's outdoor sculpture House I, conducted at Leeum, Samsung Museum of Art, Seoul, Korea. Having suffered from direct sunlight for more than a decade, the work presented severe paint fading and chalking. The purpose of the project was to provide the best possible protection by applying a durable paint material, while simultaneously preserving the colored surface that Lichtenstein had intended. A marine paint, which is relatively durable and was also utilized by the artist himself, was selected for the repainting system. An absence of practical experience and knowledge in Korea in relation both to the marine paint and its application led to many difficulties. During the actual application of the new paint, numerous technical problems arose which had to be solved in order to carry out the conservation treatment. To meet this demand, a close adherence to technical practice and an interdisciplinary study were carried out to provide the necessary understanding and compromise.  相似文献   

Regret for Complaint Withholding     

Esther Liu  Michael E. Roloff 《Communication quarterly》2016,64(1):72-92

This study examines regret for withholding relational complaints. The study sample of 393 participants completed measures of irritant frequency, irritant importance, relational intimacy, emotional distress from withholding, and regret for withholding. Irritant frequency mediated the positive relationship between length of withholding and irritant importance. This process predicted less intimacy and more emotional distress from withholding, the latter of which related to regret. Alternative paths were also found between length of withholding and regret. Results offer important implications for the role of regret management in hurtful confrontations and may inform other avoidance forms.  相似文献   

POLICY STRATEGIES FOR THE CAREER DEVELOPMENT OF WOMEN AT EUROPEAN UNIVERSITIES     

Esther K. Hicks 《Higher Education in Europe》1993,18(4):3-16

Intended as an introduction and overview, this article previews the other contributions to the topic and places them in a general introductory context. The basic question is why women, who are not currently confronted with legal or overt discrimination with regard to entering and even thriving in academic careers, are still underrepresented in the academic world in Europe, particularly in the upper echelons of academic governance and power. Several possible explanations are given, in particular the failure of women to be prepared from an early age to be competitive in ways which boys are taught to take for granted, and their failure, not so much to engage in networking, but to penetrate the networks which count, most or all of which are in fact male dominated. Among the strategies which women may use to gain both presence and power in the academic world, the use of women's studies programmes is ruled out as being ultimately counterproductive. Likewise doubt is cast on the long‐term effectiveness of affirmative action programmes. Only remedies specific to the individual conditions of each country will be really helpful in aiding women to be more numerous in higher education, particularly in positions of power. However, in all the countries in question, women must be socialized so as to be willing to adopt behaviours conducive to academic success, and they must bring to bear the full resources of the social protection and welfare systems, all of which in the different countries of the Europe Region favour not only the progress of women, but the rational use of human resources.  相似文献

Waiting to inhale: how to unhurry the moment of birth     

Malloy ME 《The Journal of perinatal education》2011,20(1):8-13

A doula and expectant mother's view of birth is forever changed when she sees a midwife simply place a newly born child below her mother at the moment of birth. The pause that the mother experiences in this moment as she studies, touches, and claims her child prompts the author to reflect in this guest editorial on ways we might be disturbing the natural sequence of birth as we deliver babies directly to their mothers' chests.  相似文献   

EQUAL OPPORTUNITY OR INTEGRATION FOR WOMEN IN THE DUTCH ACADEMIC WORLD     

Wouter Van Rossum  Esther K. Hicks 《Higher Education in Europe》1993,18(4):51-64

In 1981, the career structure in Dutch higher education was modified in such a way that performance criteria, particularly possession of a doctorate and research and publication activity, were required for promotion. In particular, the hierarchy of university posts below that of full professor was modified in such a way that persons holding so‐called WHM(senior scientific staff level) positions were required to reapply for the new UHD(associate professor) positions on a competitive basis which stressed the publication record of candidates. Using a sampling of academic women drawn from the natural sciences, the authors offer an explanation as to why women academics did less well than men in the competitions for these new posts. Although the process did not discriminate against women as such, it did not favour academics on the periphery of the profession, where many women at the time found themselves. The situation identified was the result of social factors more than of institutional discrimination. Presently, younger women ‐graduate students ‐ are rapidly moving from the periphery of the profession to the centre. Active involvement in professional networks will aid academic women in their careers; however, over‐involvement in family matters (the care network) may be harmful to the career progress of academic women.  相似文献

Antimelanogenic effects of <Emphasis Type="Italic">Inula britannica</Emphasis> flower petal extract fermented by <Emphasis Type="Italic">Lactobacillus plantarum</Emphasis> KCCM 11613P     

Eun-hye Park  Won-young Bae  Jae-yeon Kim  Kee-tae Kim  Hyun-dong Paik 《Journal of Zhejiang University. Science. B》2017,18(9):816-824

The inhibitory effects of Lactobacillus plantarum-fermented and non-fermented Inula britannica extracts on the tyrosinase activity were comparatively investigated to examine whether and how they improve the whitening activity, and the contents of total flavonoids and polyphenolics as bioactive compounds were determined. The skin whitening activity using in vitro or ex vivo tyrosinase and L-3,4-dihydroxyphenylalanine (L-DOPA) staining was examined. The total flavonoid content (TFC) was increased by 13.4% after 72 h-fermentation. The viabilities of the B16F10 cells treated with the fermented and non-fermented control extracts were 100.26% and 92.15% at 500 μg/ml, respectively. In addition, the inhibition of tyrosinase activity was increased by the fermented samples from 29.33% to 41.74% following fermentation for up to 72 h. The tyrosinase activity of the untreated control group was increased to 145.69% in B16F10 cells. The results showed that I. britannica fermented by L. plantarum dose-dependently inhibited tyrosinase activity, which was stimulated by α-melanocyte stimulating hormone. These results suggest that lactic fermented I. britannica extracts can be used as effective skin-whitening materials.  相似文献
