The Determinants of Trust and Credibility in Environmental Risk Communication: An Empirical Study 总被引:8,自引:1,他引:8
This study examines a key component of environmental risk communication; trust and credibility. The study was conducted in two parts. In the first part, six hypotheses regarding the perceptions and determinants of trust and credibility were tested against survey data. The hypotheses were supported by the data. The most important hypothesis was that perceptions of trust and credibility are dependent on three factors: perceptions of knowledge and expertise; perceptions of openness and honesty; and perceptions of concern and care. In the second part, models were constructed with perceptions of trust and credibility as the dependent variable. The goal was to examine the data for findings with direct policy implications. One such finding was that defying a negative stereotype is key to improving perceptions of trust and credibility. 相似文献

The impact and management of cognitive gap in high performance product development organizations 总被引:1,自引:0,他引:1
Kathryn W. Jablokow David E. Booth 《Journal of Engineering and Technology Management》2006,23(4):313-336
The close alignment of applied research and development units with manufacturing operational structures can provide excellent opportunities for maintaining robust product pipelines and reducing product development cycle times. Within such an integrated organizational model (IOM), however, lies a potentially disruptive psychological mechanism that can lead to the dissolution of this delicate partnership if it is not handled properly. This mechanism is cognitive gap, which can take several basic forms: first, as differences between the nature and difficulty of the problem at hand and the cognitive resources of the problem solvers tasked with its solution; and second, as differences between the cognitive abilities and approaches of the problem solvers themselves. In this paper, we define and discuss cognitive gap within the context of Kirton's Adaption-Innovation theory, a useful framework for understanding problem solving (and problem solvers) in general. Specific implications (both favourable and potentially destructive) of cognitive gaps for high performance product development organizations are discussed, and suggestions for their effective management are offered. 相似文献

The aim of this paper is to summarize literature relevant to the professional organization and to present a contemporary analysis of the archetype concept in this field. In order to understand recent and ongoing changes in professional organizations, the paper begins with a review of how the professional archetype evolved from the 1960s to 1990. Then, with examples from contemporary accounting, health care and law organizations, it considers the processes by which an institutionalized archetype can change. Forces for change – such as deregulation, competition, technology and globalization – can challenge the interpretive scheme and eventually delegitimize the existing archetype. At the same time, significant environmental changes can override isomorphic pressures and de‐institutionalize the long‐accepted structures. Thus we herald the emergence a new professional archetype – or perhaps several competing archetypes. Finally, the paper reviews the evolving field of professional organization as a whole, and understands the extant archetypes. A typology of professional organizations is proposed that currently seems to have three clusters of organizations – possibly three competing archetypes – namely, the traditional professional partnership, the specialized ‘Star’ form and the corporate global professional network, or GPN. 相似文献

This paper examines recent changes in weekly income levels and dispersion for Māori, New Zealand’s indigenous ethnic group.
Changes in the Māori income distribution between 1997 and 2003 reflect rapid increases in economic growth and employment rate.
A reduced proportion of people had zero or benefit-level incomes and a higher proportion had high incomes. Income inequality
declined for working-aged Māori and was stable for employed Māori. The average income gap between Māori and Europeans declined.
The increased Māori employment rate during this period was the single most important driver of changes in the Māori income
distribution.

Demographic and Health Survey data from nine African countries make it clear that HIV/AIDS prevention knowledge has been increasing.
Still, in many cases, fewer than half of adult respondents can identify specific prevention behaviors. Knowledge is lowest
in rural areas and among women. HIV testing generally remains rare but is highly variable across countries, likely reflecting
differences in the supply of testing services. In most cases, schooling and wealth impacts on prevention knowledge have either
been stable or have increased; hence, in the majority of contexts, initial disparities in knowledge by education and wealth
levels have persisted or widened.

A definition of reproducibility in Guttman Scaling and two chance measures of reproducibility are suggested. The first measure assumes that the items are independent. The second method assumes nonindependent items and fits respondent and item margins by an iterative method used in fitting log-linear models. Chance reproducibility is conceptualized in terms of assumptions about respondent variability. 相似文献

Family size and children’s education in Vietnam 总被引:2,自引:0,他引:2
Data from the nationally representative 1994 Inter-Censal Demographic Survey are used to examine the association between family size and children s schooling in Vietnam. The data provide information on several education measures for all children over age 10, including children no longer residing in the household. Although a clear inverse bivariate association between family size and children s school attendance and educational attainment is evident, multivariate analysis controlling for urban/rural residence, region, parents’ education, household wealth, and child’s age, reveals that much of this association, especially that predicting educational attainment, is attributable to these other influences. Moreover, much of the effect that remains after statistical adjustment for the other influences is seen mainly at the largest family sizes. We consider the implications of these findings for current population policy in Vietnam and the possible features of the Vietnamese context that might account for the modest association. 相似文献
