This article offers an analysis of the impact of professional social-media engagement upon authors. Authors primarily use Facebook, Twitter and there is growing use of Pinterest. Authors use social-media platforms primarily for marketing, publicity and making contact with readers. They tend to adopt a multi-layered approach to self-presentation and the lines between their ‘public’ and ‘private’ identities are blurred. The research reveals a limited author-reader community, but a much stronger online author–author community, founded upon practical support and encouragement. There are implications for the publishing industry as authors believe their publishers lack social-media expertise. The commercial benefits of maintaining a social-media presence are unclear for many authors.  相似文献

From the standpoint of “sender,” “receiver,” “theorist,” or “critic” the concept of the “message” must be augmented if we are to give a satisfactory account of communication. This essay is an attempt to lay the groundwork for the analysis of those elements that can be referred to as the “paramessage.”  相似文献

Given the growth in scuba diving activities and the importance of environmental education programs to alleviate the potential impacts on coral reef ecosystems, there is a need to better understand the diving community, its environmental knowledge, and subsequent behavioral actions. The purpose of this study was to explore the role or influence of specialization in scuba diving (as a moderator and mediator) on the relationship between marine-based environmental knowledge and behavior. Four hypotheses were formulated and empirically tested. Data from 370 scuba divers were collected (May-September 2002) in the St. Petersburg/Sarasota region of southwestern Florida. Marine-based environmental knowledge (11 items) and behaviors (16 items) were employed, along with recreation specialization (17 items) adapted from the literature. Specialization in scuba diving acted as a strong partial mediator but failed to be significant when tested as a moderator. Among scuba divers, marine-based knowledge did predict overall and specific proenvironmental behaviors; however, the level of specialization played a strong role in mediating the relationship.  相似文献

Behind the High Achievement of East Asian Students   总被引:1,自引:0,他引:1  
Hong Kong, Japan, Korea and Singapore are the only East Asian countries in the Third International Mathematics and Science Study (TIMSS), but students in these 4 countries outperformed their counterparts in the TIMSS mathematics test. An examination of the student background information showed that there was little commonality among the 4 countries which can be used to explain the superior achievement of their students. The only common background data for the 4 places were their high population density and large class size, which are, in general, not considered favorable factors for achievement. An investigation of the TIMSS attitude data also failed to locate common attitudes that were unique to the 4 countries and which can be used to explain the high achievement of their students. The questionnaire data however indicated that the superior results of the East Asian students might have been achieved at the expense of other aspects of the development of the students. The results also showed that students in the 4 countries displayed relatively negative attitudes towards mathematics, including the lack of confidence in doing mathematics. The predominant Confucian culture in the 4 countries will be discussed in an attempt to explain the negative attitudes of the East Asian students, but it is not clear how these cultural values can be used to explain their superior achievement.  相似文献

This study examined context variables (reporter speculation, multiple viewpoints, and story emphasis) and source variables (anonymous sources and source transparency) in broadcast television coverage of the 2004 Democratic presidential primaries. Primary coverage was compared with coverage of other major stories. Primary coverage was no more focused on conflict than were other major stories. Primary coverage was, however, more focused on winners and losers, and primary reporting was more likely to include reporter speculation. Primary stories were just as likely to include anonymous sources as were other major stories, but primary stories also were more likely than other major stories to fully identify sources.  相似文献

This study compared the relationships between the goal orientations, learning strategies, and mathematics achievement of Chinese Miao and Han students. A total of 211 Han and 321 Miao fifth‐ and sixth‐grade students from Qiandongnan participated in the study. The results suggest that, in both samples, mastery orientation positively predicted the use of surface/deep learning strategies and mathematics achievement, and that performance‐approach orientation significantly predicted the use of surface strategies. Ethnic differences were also detected. The positive relationship of the performance‐approach orientation to deep strategies was stronger among the Han than the Miao students. Overall, our findings confirm that goal orientations have an important influence on Chinese students’ strategy use and achievement and that ethnic differences affect the patterns of these relationships. Possible explanations for the results and the practical implications for school practitioners are discussed.  相似文献

Research Findings: A difficulty for developmental researchers is disambiguating children's general maturation from the influence of schooling. In this study, we use a natural experiment to examine the influence of prekindergarten and kindergarten schooling experiences on the development of literacy and mathematics. Children (n = 60) whose birthdates fell within 2 months of the state-determined cutoff date for prekindergarten and kindergarten entry were administered 4 subtests of the Woodcock–Johnson III Tests of Achievement in the fall and spring of the school year. Using hierarchical linear modeling coupled with propensity score matching, we found that children who were starting kindergarten and who had prior experience in prekindergarten had higher scores on measures of phonological awareness, early reading, and mathematics skills than did children who had not attended prekindergarten previously, even though they were essentially the same age. Fall vocabulary scores did not differ in relation to whether children had prekindergarten experience. In addition, although children who attended kindergarten as well as those who attended prekindergarten exhibited growth on all measures during the school year, children who attended kindergarten demonstrated greater gains in early reading and vocabulary during the school year. Practice or Policy: These findings highlight the potential of early schooling processes to facilitate children's intellectual growth.  相似文献
