In this article, I describe the contours of global media networks in terms of interorganizational linkages and spatial distribution of foreign direct investment in the entertainment industry. The results of multidimensional scaling revealed that there were significant differences in the positional structures of global networks in the entertainment industry. However, in the case of the structural relations between the interorganizational and geographical dispersion networks, the quadratic assignment procedure analyses revealed structural similarities between both networks in the entertainment industry. A multiple regression analysis also showed music and film industries played a significant role in explaining interorganizational and geographical dispersion networks. The findings indicate the benefit of distinguishing between interorganizational and geographic dispersion networks in understanding global media networks.  相似文献

This study examined how news organizations employed Twitter as a news source, based on information subsidy and gatekeeping perspectives. News content analysis from 7 major media entities in 2010–2011 demonstrated that journalists embraced Twitter as a new channel for information gathering. TV frequently cited Twitter as a sole or a primary source. However, despite active usage of Twitter overall, journalists in both TV and newspapers maintained conventional routines by relying primarily on Twitter accounts of official sources. The popularity of Twitter accounts, as indicated by the number of followers, did not contribute to attracting more attention from journalists.  相似文献

Adapted from Chang et al.'s (2006) models, this study examines factors that influence adoption and non-adoption of social network sites (SNS) in adopters (Continuers, Discontinuers) and non-adopters (Potentials, Resistors). Chi-square and t-test were used to analyze the survey data of Singapore's working adults and Internet users (N =222). The findings reveal innovation characteristics (relative advantage, compatibility, complexity) and perceived popularity differ significantly in three pairs of adopter categories. Results show Continuers and Potentials are concerned more about image than Discontinuers and Resistors, while technology cluster differs between adopter vs. non-adopter and Continuers vs. Discontinuers. Moreover, the study suggests younger people tend to adopt SNSs, females continue to use SNSs more, and potential SNS users are more innovative. Lastly, a regression model to forecast the adoption of SNSs is proposed in which age, compatibility, technology cluster, and perceived popularity are predictors.  相似文献

This study examined participants’ learning experiences in the context of a six-week massive open online course (MOOC) in journalism with five thousand students from 137 countries. Three research questions were asked: (1) Who are the students and why are they enrolled in this MOOC?, (2) How much time have the students spent in taking this MOOC and have they completed all the assignments?, and, (3) What have they learned and what aspects of this MOOC do the students find most helpful? Four hundred and nine students responded to a survey and forty-four responded to interview questions. The main findings showed 84% of the participants were working professionals and only 28.9% were from a journalism background. Of those who did not complete the course, lack of time was the top reason. Most participants reported a positive learning experience, but lack of feedback and/or poor quality were reported as negative experiences. The discussion forum was the least liked aspect of the course.  相似文献

This project describes the trialling of a new form of cooperative learning strategy, in the form of a game known as EcoRangers. EcoRangers is a multi‐player game designed to run on mobile phones, written specifically for education. EcoRangers is one of the first, if not the world's first, instances of this totally new genre of pedagogical tools (i.e. collaborative handheld educational games). In its current iteration EcoRangers is designed to help students practise skills of relevance to the social studies syllabus for Grades 9 and 10 in Singapore's education system, specifically through the pedagogical strategy known as the ‘structured academic controversy’, in which learners debate an open‐ended problem from a variety of perspectives. The trialling was done in three secondary schools, among 50 Grade 9 students. These students were taken through two distinct fieldwork tasks in March–July 2004, with the game being introduced as part of a post‐fieldwork activity.

Jeux collaboratifs sur portables en éducation

Ce projet décrit l'expérimentation d'une nouvelle forme de stratégie d'apprentissage coopératif sous la forme d'un jeu connu sous le nom d'EcoRangers.EcoRangers se joue à plusieurs.Il a été conçu pour fonctionner sur les téléphones portables et composé spécialement pour L'éducation. EcoRangers est un des premiers sinon le premier exemple au monde de cette catégorie d'outils pédagogiques (celle des jeux éducatifs collaboratifs portables) totalement nouvelle. Sous sa forme actuelle EcoRangers a été conçu pour aider les élèves à pratiquer des savoir faire correspondant au cursus de sciences sociales pour les classes 9 et 10 du système Singapourien(13‐14 ans) et plus particulièrement la stratégie connue sous le nom de « controverse académique structurée » au cours de laquelle les apprenants débatent d'un problème ouvert en partant de perspectives différentes.L'expérience a été menée dans trois écoles secondaires avec 50 élèves de 9e.Ces élèves ont participé à deux tâches « de terrain » distinctes entre mars et juillet 2004,le jeu étant présenté comme faisant partie d'une activité « d'après‐terrain ».

Gemeinschafliches Spielen auf Handhelds oder Handys als Unterricht

Das Projekt beschreibt den Versuch, eine neue Art von Gruppenlernen zu testen, die auf ein Spiel zurück greift, das EcoRangers genannt wird. Dies ist ein Spiel für mehrere Spieler, das auf Handys abläuft und ein Lernspiel ist. EcoRangers ist eines der ersten, wenn nicht sogar das erste Spiel in der Welt, dieser Art. In seiner gegenwärtigen Fassung hilft EcoRangers den Schuelern, Fertigkeiten im Bereich der Social Studies (Gemeinschaftskunde) einzuueben (Lehrplan für Stufe 9 und 10 in Singapur), insbesondere dadurch, dass die Strategie der ‘strukturierten, akademischen Diskussion’ angewendet wird, bei der die Schueler ein offenes Problem aus sehr unterschiedlichen Perspektiven besprechen. Der Versuch wurde in drei Schulen (Sek.II) durchgeführt, wobei 50 Schueler aus Stufe 9 waren. Diese wurden im Rahmen eines Aufenthalts im Gelaende (Maerz–Juli 2004) mit dem Spiel konfrontiert, das als eine Tätigkeit nach dem Arbeiten im Gelände eingefuehrt wurde.  相似文献

For many reasons, students with disabilities are not as thoroughly represented in science careers as are their nondisabled peers. In this case study, the authors explore the effects an informal education program focused on environmental science and delivered to college-bound students with disabilities had on comfort level with science and interest in science careers. Results indicate that the informal nature of the program was well-received and increased individuals' confidence in their science ability. The authors present suggestions for translating this experience into a traditional classroom setting.  相似文献

This paper analyses entrepreneurial orientation (EO) in multinational corporations (MNCs) and develops a new typology of MNC EO based on combining R&D and asset growth investment intensities as orthogonal resource allocations. A cluster analysis of US MNCs on these two dimensions reveals three types of entrepreneurial stance: conservative, aggressive-asset growth and balanced. Internal knowledge network characteristics are shown to vary by stance, with more aggressive stances linked to knowledge governance supportive of the entrepreneurship process. In linking entrepreneurial orientation to the knowledge network of the MNC, this paper identifies factors important to the strategic management and on-going renewal of MNCs. In addition, the vector of R&D investment vs. asset growth investment is an indicator of entrepreneurial aggression and presents a new method of understanding the international strategies of MNCs.  相似文献

The purpose of this study was to investigate kinematic and spatiotemporal variables of aquatic treadmill walking at three different water depths. A total of 15 healthy individuals completed three two-minute walking trials at three different water depths. The aquatic treadmill walking was conducted at waist-depth, chest-depth and neck-depth, while a customised 3-D underwater motion analysis system captured their walking. Each participant’s self-selected walking speed at the waist level was used as a reference speed, which was applied to the remaining two test conditions. A repeated measures ANOVA showed statistically significant differences among the three walking conditions in stride length, cadence, peak hip extension, hip range of motion (ROM), peak ankle plantar flexion and ankle ROM (All p values < 0.05). The participants walked with increased stride length and decreased cadence during neck level as compared to waist and chest level. They also showed increased ankle ROM and decreased hip ROM as the water depth rose from waist and chest to the neck level. However, our study found no significant difference between waist and chest level water in all variables. Hydrodynamics, such as buoyancy and drag force, in response to changes in water depths, can affect gait patterns during aquatic treadmill walking.  相似文献

The purpose of the study was to investigate the effect of different kicking modality, i.e., erratic-dynamic target (EDT) versus static target (ST) on the performance of the roundhouse kick in two groups of taekwondo athletes of different skill level. Three-dimensional analysis and surface electromyography (SEMG) analysis were performed on 12 (Group A: six sub-elite, Group B: six elite) athletes to investigate muscle co-activation pattern under two conditions, i.e., EDT versus ST. In the results, the muscle recruitment ratio of the agonistic muscles was higher for Group A, whereas Group B had higher recruitment ratio for antagonist muscles. Overall, the co-activation index (CI) of hip joints appeared higher in the extensors for Group A, whereas higher CI was observed in flexor muscles for Group B with comparatively higher CI during EDT condition than ST condition. Higher value of CI was observed in flexor muscles of the knee joints among Group A during EDT conditions, in contrast, higher CI in the extensor muscles was observed among Group B during ST conditions. In conclusion, the study confirmed that erratic-dynamic movements of target could change the movement coordination pattern to maintain the joint stability of participants.  相似文献
