In our work over the past 15 years, we have been guided by a premise, right or wrong, that fundamental changes in how organizations work require fundamental changes in how we think and interact. Changes in the “outer world” do not necessarily produce change in the “inner world”… I am skeptical of what can be accomplished by changes in structure alone.… What leads us to believe that lots of local managers, focused on their own profits, will be any more far‐sighted than a few corporate managers focused on corporate profits? Will they be any better at systems thinking? … What good is it to have more free movement of information if people cannot discuss the information that is most important, but that is also the most threatening?

Learning the value of environmental signals and using that information to guide behavior is critical for survival. Stress in childhood may influence these processes, but how it does so is still unclear. This study examined how stressful event exposures and perceived social isolation affect the ability to learn value signals and use that information in 72 children (8–9 years; 29 girls; 65.3% White). Stressful event exposures and perceived social isolation did not influence how children learned value information. But, children with high stressful event exposures and perceived social isolation were worse at using that information. These data suggest alterations in how value information is used, rather than learned, may be one mechanism linking early experiences to later behaviors. 相似文献

The potential of pictorial and verbal metaphors to gain attention and enhance persuasion is considerable. Few scholars, however, have investigated the persuasive effects of metaphor in health messages. We applied a 2 × 2 factorial experiment to examine the effects of metaphor use (metaphor/literal) and message format (verbal/pictorial) on cognitive processing and persuasive outcomes of condom promotion messages. Results showed no significant differences in cognitive processing according to metaphor or format, but there were differences in attitudes and behavioral intentions according to metaphor and format, with literal and verbal messages performing best. Potential explanations for findings and implications for future research and health message design are discussed. 相似文献

Building on research proposing reciprocal journalism as a concept underlying participatory practices and norms in journalism, this study examines how reciprocity might meaningfully be measured in a journalistic context. Using a survey of US journalists, this study adapts measures of reciprocal attitudes and behaviors to journalistic practices. It also develops measures of direct, indirect, and sustained reciprocity as applied to journalism, and explores the relationship between each of these reciprocal forms and one type of participatory behavior: interacting with audiences online. The results indicate that some measurements of positive reciprocity can be meaningfully translated to a journalistic environment and may help to predict forms of audience interaction. For future research, the findings point to the potential for forms of reciprocity to be explored as antecedents for other journalistic norms and practices. 相似文献

The purpose of the present study is to examine the language characteristics of a few states' large-scale assessments of mathematics and science and investigate whether the language demands of the items are associated with the degree of differential item functioning (DIF) for English language learner (ELL) students. A total of 542 items from 11 assessments at Grades 4, 5, 7, and 8 from three states were rated for the linguistic complexity based on a developed linguistic coding scheme. The linguistic ratings were compared to each item's DIF statistics. The results yielded a stronger association between the linguistic rating and DIF statistics for ELL students in the “relatively easy” items than in the “not easy” items. Particularly, general academic vocabulary and the amount of language in an item were found to have the strongest association with the degrees of DIF, particularly for ELL students with low English language proficiency. Furthermore, the items were grouped into four bundles to closely look at the relationship between the varying degrees of language demands and ELL students' performance. Differential bundling functioning (DBF) results indicated that the exhibited DBF was more substantial as the language demands increased. By disentangling linguistic difficulty from content difficulty, the results of the study provide strong evidence of the impact of linguistic complexity on ELL students' performance on tests. The study discusses the implications for the validation of the tests and instructions for ELL students. 相似文献

Efforts to improve science education include university science departments hiring Science Faculty with Education Specialties (SFES), scientists who take on specialized roles in science education within their discipline. Although these positions have existed for decades and may be growing more common, few reports have investigated the SFES approach to improving science education. We present comprehensive data on the SFES in the California State University (CSU) system, the largest university system in the United States. We found that CSU SFES were engaged in three key arenas including K-12 science education, undergraduate science education, and discipline-based science education research. As such, CSU SFES appeared to be well-positioned to have an impact on science education from within science departments. However, there appeared to be a lack of clarity and agreement about the purpose of these SFES positions. In addition, formal training in science education among CSU SFES was limited. Although over 75% of CSU SFES were fulfilled by their teaching, scholarship, and service, our results revealed that almost 40% of CSU SFES were seriously considering leaving their positions. Our data suggest that science departments would likely benefit from explicit discussions about the role of SFES and strategies for supporting their professional activities. 相似文献

In this article, the collection of articles in this issue are synthesized to discuss conceptualizations of adaptive teaching as a means to foster spaces for adaptive teaching in today's complex educational system. Themes that exist across this collection of articles include adaptive teachers as constructivists, adaptive teachers as knowledgeable professionals, adaptive teachers as reflective educators, and contexts that support teacher adaptations. These themes are discussed with implications for teachers, teacher educators, administrators, and other educational stakeholders. Finally, the discussion shifts its focus to discuss future directions. 相似文献
