The current content analysis examined representations of body type on prime time television. A composite week of U.S. television was randomly sampled, yielding 1,254 characters in 89 programs. Character attributes also were evaluated. Results suggest that women have become increasingly thin on TV. Thinner characters were more attractive than overweight characters. The few obese and overweight characters presented were less articulate, less intelligent, and more likely to be ridiculed than thinner characters. Black characters on prime time were heavier than other racial/ethnic groups and these characters were seen as more likeable. Implications are discussed from social cognitive theory and cultivation theory perspectives.  相似文献

Social media use by government: From the routine to the critical   总被引:1,自引:0,他引:1  
Social media and online services with user-generated content (e.g., Twitter, Facebook, Flickr, YouTube) have made a staggering amount of information (and misinformation) available. Government officials seek to leverage these resources to improve services and communication with citizens. Significant potential exists to identify issues in real time, so emergency managers can monitor and respond to issues concerning public safety. Yet, the sheer volume of social data streams generates substantial noise that must be filtered in order to detect meaningful patterns and trends. Important events can then be identified as spikes in activity, while event meaning and consequences can be deciphered by tracking changes in content and public sentiment. This paper presents findings from a exploratory study we conducted between June and December 2010 with government officials in Arlington, VA (and the greater National Capitol Region around Washington, D.C.), with the broad goal of understanding social media use by government officials as well as community organizations, businesses, and the public at large. A key objective was also to understand social media use specifically for managing crisis situations from the routine (e.g., traffic, weather crises) to the critical (e.g., earthquakes, floods).  相似文献

Cultures of performativity in English primary schools refer to systems and relationships of: target‐setting; Ofsted inspections; school league tables constructed from pupil test scores; performance management; performance related pay; threshold assessment; and advanced skills teachers. Systems which demand that teachers ‘perform’ and in which individuals are made accountable. These policy measures, introduced to improve levels of achievement and increased international economic competitiveness, have, potentially, profound implications for the meaning and experience of primary teachers’ work; their identities; their commitment to teaching; and how they view their careers. At the same time as policies of performativity are being implemented there is now increasing advocacy for the adoption and advancement of ‘creativity’ policies within primary education. These major developments are being introduced in the context of a wide range of social/educational policies also aimed at the introduction of creativity initiatives into schools and teaching. This complex policy context has major implications for the implementation process and also primary teachers’ work and how they experience it. The ethnographic research reported in this article has been conducted over a school year in six English primary schools in order to analyse the effects of creativity and performativity policy initiatives at the implementation stage. The article concludes by arguing that in the schools of our research the drive to raise pupil test scores involves both performative and creative strategies and that this critical mediation goes beyond amelioration toward a more complex view of professional practice. Implementing creativity and performativity policies provided important contextual influencing factors on teacher commitment. These were: curriculum coverage and task completion; and providing psychic rewards of teaching.  相似文献

Many studies have demonstrated the facilitating role of rhetorical devices in text comprehension, but there are also studies where rhetorical devices have not shown such effect. The present study sets out to explore whether readers’ knowledge of rhetorical devices (that is, rhetorical competence) moderates their effectiveness beyond general comprehension skills and, consequently, whether rhetorical competence may be considered a component skill of reading comprehension. 192 sixth- to seventh-grade students were assessed on rhetorical competence and were required to read a difficult marked text with specific rhetorical devices (a refutation, an objective, and four organizational signals) or the same text without them. After reading, students produced a summary in order to obtain three dependent variables: main ideas (as a measure of participants’ ability to select relevant information from the text), causal links between them (as an indicator of participants’ ability to grasp the logical structure of the text and to organize its ideas), and the combination of main ideas plus causal links (as an indicator of participants’ global comprehension of the text). Analyses controlling for general comprehension skills and other important variables (working memory, prior knowledge, decoding) demonstrated that: (a) readers of the marked text scored higher in terms of all dependent variables, and (b) rhetorical competence level moderated the effect of rhetorical devices on the composite measure (main ideas plus causal links) and on the organization of the summary by means of causal links.  相似文献

The purpose of this article is to examine the sources of differences in motivation and other psychological characteristics, specifically the role of childhood environments, in engendering or promoting adult creative productive achievement. A model is presented in which it is proposed that the environmental conditions of creative producers result in responses that include the development of several key personality characteristics or coping strategies such as a preference for time alone, an ability to cope with high levels of anxiety or tension, freedom from conventionality, and the use of intellectual activities to fulfill emotional needs. The conditions in the environment often result from some kind of stress within the family, which is in part, a function of characteristics of the family, the broader context surrounding the family, and characteristics of the child.  相似文献

This paper has two aims. First, it reviews literature about conceptual change and about the study of concepts more broadly. The principal claim is that much prior work has suffered from inexplicitness and imprecision in terms of what constitutes a concept. Second, we introduce a theory of one particular type of concept. A coordination class is a systematic collection of strategies for reading a certain type of information out from the world. We identify both structural components and performance properties of coordination classes. Using this theory, we analyse protocol data from a student with respect to the difficult concept of force in Newtonian mechanics.  相似文献

The purpose of the study was to examine, using an ethnographic perspective, young children's gender behaviors. Four children, 3 to 5 years old, are described using videotaped observations of a university laboratory preschool. This study revealed, through individualprofiles of the children, that gender behaviors in early childhood are constructed by the individual interacting with her his social world. Also, gender behaviors were found to be integrated with other social processes, namely, student and peer behaviors. Finally, sociocultural and poststructuralist perspectives revealed the obvious and subtle gender behaviors of young children. Thus, researchers using ethnographic methods can explain the complexity in which children experience becoming a person .  相似文献

Abstract

Framing professional learning as a social practice underscores the interplay between subjective meaning systems and objective conditions of the social space where learning occurs. Drawing on Pierre Bourdieu’s theory of social practice, and methodologically guided by critical realism, the paper identifies what constitutes effective teacher professional learning through mentoring. The empirical focus of the paper is an Early Childhood teacher mentoring programme in the state of Victoria, Australia. The findings show that: (a) relevant circumstances that make teacher professional learning a necessity are associated with individual aspirations and systemic requirements; (b) collegial relationships and critical deliberation constitute meaningful learning experiences; and (c) teacher learning takes place in the domains of professional dispositions, pedagogical knowledge and social capital. The implication is that in designing professional development programmes such as mentoring, it is important to take teachers’ contexts of practice into account; conceptualise learning as a socially situated practice; and recognise the value of teachers’ lived experiences as a locus of deliberation and learning.  相似文献
