ABSTRACT

This experimental study examined the impact of posting different types of tweets on a journalist’s perceived credibility. Three-hundred-and-eighty-seven participants were randomly assigned into one of three groups. One group saw tweets from a journalist that were about the journalist’s personal life, another group saw tweets from the same journalist that were written objectively about news stories, and the third group saw tweets from the same journalist that contained the journalist’s opinion regarding news stories. Participants who read the personal tweets about the journalist’s life rated the journalist highest in perceived credibility. The perceived credibility of the journalist was ranked significantly lower by participants who read the tweets that only contained the journalist’s opinion. Participants were also asked to rate the credibility of the organization for which the journalist worked. The perceived credibility of the organization was rated significantly higher by those who read the objective tweets. Organizational credibility was rated lowest by those who read the tweets that contained the journalist’s opinion. This study has important implications for journalists who use Twitter and wish to improve their personal and organizational perceived credibility.  相似文献

This paper addresses the positioning of science, technology, engineering and mathematics (STEM) outreach programmes within universities’ operations. Though universities in many respects form a rather homogenous international community, there is wide diversity in regard to the provision of STEM outreach by different institutions. To explain this diversity, a conceptual framework was developed by using the Theory of Legitimacy as an organising concept. The framework considers two opposing scenarios that form a continuum between them, namely: ‘top‐down’ initiative by the university governance versus ‘bottom‐up’ grass‐roots initiative. Using the Theory of Legitimacy, internal and external outreach relationships are characterised and explained under the two scenarios. The framework was applied to two settings chosen due to their essential differences in outreach provision, namely, Australia and Israel. The differences that were found in internal and external legitimacy provide a useful lens for examining the low‐performing, fragile system in Australia as compared with the high‐performing, thriving system in Israel.  相似文献

Dyslexia is a complex reading and writing disorder with a strong genetic component. In a German case-control cohort, we studied the influence of the suspected dyslexia-associated gene DCDC2. For the first time in a German cohort, we describe association of a 2445 basepair deletion, first identified in an American study. Evidence of association for three DCDC2 single nucleotide polymorphisms (rs807724, rs793862, rs807701), previously identified in German or American cohorts, was replicated. A haplotype of these polymorphisms showed evidence for association as well. Thus, our data further corroborate association of DCDC2 with dyslexia. Analysis of functional subgroups suggests association of investigated DCDC2 variants mainly with nondysphonetic, nonsevere, but probably dyseidetic (surface) dyslexia. Based on the presumed function of DCDC2, our findings point to a role of impaired neuronal migration in the etiology of the disease.

This article investigates how schoolteachers’, school leaders’ and college teachers’ involvement affects placement schools as professional learning communities. Norwegian teacher education is used as a case. The first part builds on a survey among schoolteachers and mentors at 111 placement schools in Norway. It documents great variety in the level of engagement. Interviews with mentors, school leaders and college teachers reveal how cooperation between colleges and placement schools, as well as the school leaders’ commitment, influences the quality of placement. The school leaders’ role proves to be important in developing the schools as professional learning communities, and they seem to have a significant impact on the work of the mentors. The data also show that there is a need for a more substantial cooperation between college teachers and mentors about the student teachers’ professional development as well as a need for a more systematic integration of learning in the two learning contexts.  相似文献

The goal of this article is to examine the strategic choices of firms collecting consumer data online and to identify the roles and obligations of the actors within the current network of online tracking. In doing so, the focus shifts from placing the onus on individuals to make an informed choice, to justifying the roles and responsibilities of firms when gathering, aggregating, and using consumers' interests or behavior online. Firms online are uniquely positioned to undercut or to respect privacy expectations within three possible roles: as a member of a supply chain of information traders, within a network of surveillance online, and as an arm of law enforcement. These firms benefit from aggregating and analyzing consumer data and have an associated responsibility to not only minimize the harm to consumers but also to enact change where the firm is in the most knowledgeable and powerful position.  相似文献

Abstract

This article offers insights on how students experienced and made sense of their learning in a trimester-long high school Gay and Lesbian Literature course. Drawing on questionnaires and interviews that the students completed as part of a larger ethnographic study of this class, the author shows how a queer-themed literature curriculum is relevant for both LGBTQ-identifying and straight–identifying students and contributes to a better school climate.  相似文献

Lack of school engagement among adolescents in this country remains a problem that can have very serious consequences including increased risk for school dropout, substance use, teenage pregnancy, and criminal activity. Clearly, identification of psychological variables (self‐variables) of individuals that facilitate or hinder adolescents' levels of school engagement would contribute greatly to the understanding of how to increase adolescents' psychological well‐being and their achievement motivation and associated school engagement. The present study examined the degree of association of three specific self‐variables (self‐efficacy, goal orientation, and fear of failure) with school engagement for high school students. The results and implications for intervention and future research are addressed. © 2003 Wiley Periodicals, Inc. Psychol Schs 40: 417–427, 2003.  相似文献
