Innovators and imitators: Organizational reference groups and adoption of organizational routines 总被引：3，自引：0，他引：3
Firms vary greatly in their rates of creating and adopting technological and organizational innovations, in part because of their choice of reference group. We argue that the selection of a reference group is a crucial and neglected source of firm heterogeneity. Comparisons to the average of other firms in a population cause most firms to adopt innovations once they are widely accepted. A distinctive feature of the minority of innovating firms that create innovations or adopt them early is that they compare themselves with, compete with, and try to differ from other innovating firms, whereas the majority of firms compare themselves with, and conform to, a broader group of firms. We elaborate this argument based on the behavioral theory of the firm and institutional theory, and test it on a two-period survey on adoptions of innovative organizational forms in Europe and the US. The analysis shows the predicted differences in the adoption patterns of innovating and imitating firms. 相似文献

Effects of student versus staff tutoring on student learning in a problem-based, health sciences curriculum were studied. Academic achievement of 334 tutorial groups guided by staff tutors was compared with achievement of 400 groups guided by student tutors. In addition, students rated their tutor's performance on four behaviors considered critical to facilitating student learning. Overall, students guided by a staff tutor achieved somewhat better. In terms of practical significance, the difference was, however, fairly small. Staff tutors were rated as more knowledgeable and their contributions as more relevant. In addition, they asked stimulating questions to a larger extent. However, an interaction effect was found between the ratings and the year of study: Peer tutors displayed the supportive behaviors more extensively in the first year, whereas staff tutors' ratings were higher as the curriculum advanced. These results were interpreted in terms of the cognitive congruence framework.Parts of this article have been presented to the Annual Meeting of the American Educational Research Association, Atlanta, GA, April, 1993. 相似文献

Technological agglomeration and the emergence of clusters and networks in nanotechnology 总被引：3，自引：0，他引：3
Research and development at the nanoscale requires a large degree of integration, from convergence of research disciplines in new fields of enquiry to new linkages between start-ups, regional actors and research facilities. Based on the analysis of two clusters in nanotechnologies (MESA+ (Twente) and other centres in The Netherlands and Minatec in Grenoble in France), the paper discusses the phenomenon of technological agglomeration: co-located scientific and technological fields associated to coordinated technology platforms to some extent actively shaped by institutional entrepreneurs. Such co-location and coordination are probably a pre-requisite for the emergence of strong nanoclusters. 相似文献

The past is not in the classroom to observe and study. Thus, creating a lively and understandable image of a past period or situation is an achievement to be learned. A variety of tasks can be used to stimulate students to create an image of the past. In this experimental study, 151 grade 9 students (14–16 years old) participated by completing a drawing task or a writing task on the Roman Forum in Ancient Rome. Their products were compared. Additionally, the students’ perceptions of the tasks were explored by means of a questionnaire and an interview. The findings show that the written products contained more information elements than the drawings. However, in terms of the historical plausibility of the product, the drawn products and written products were comparable. Students who made a drawing reported higher situational interest than students who wrote a text.

Tasks which invite students to identify with historical actors and describe their perspectives are a common phenomenon in history education. The aim of this study is to explore the differences in students’ answers when completing a writing task in first person (‘imagine you are in the past’) or in third person (‘imagine someone in the past’), or a task in which such imagination is not explicitly asked. Furthermore we investigated the effects of the type of task on topic knowledge and situational interest. Students in Dutch secondary education (N = 254) participated by completing a task on the Dutch Iconoclasm. Our analysis of student answers focused on aspects of historical empathy: historical contextualization, affective elements and perspective taking.
Results were that all students gained some knowledge from the task, regardless of the type of task they completed. Students’ situational interest also did not differ between the three tasks. However, students’ written work showed that the first- and third-person writing tasks stimulated students to imagine concrete details of the past and emotions of historical actors. Students who were not explicitly asked to imagine themselves or someone in the past included more perspectives into their writings. Students who completed the task in first person tended to show more presentism and moral judgements of the past than students who completed a task in third person. 相似文献

The present study shed light on the continuing debate among students of political socialisation regarding the effects of civic education on the upholding of democratic attitudes. Our major conclusion is that civic education, in and of itself, has only minor effects on democratic attitudes of pupils. Furthermore, among pupils who attended civic education classes, democratic class climate would have a crucial effect on the internalisation of democratic attitudes, and the association between sociodemographic characteristics and democratic attitudes is partially mediated by perception of democratic class climate. The findings offer a model which involves demographics and class climate for predicting the success of civic education in meeting its main goal—the absorption and internalisation of democratic attitudes. Thus, we hope to take the ongoing debate in the field at least one small step forward. 1 相似文献

The Questionnaire on Teacher Interaction (QTI) is a teacher–student relationship measure whose underlying two-dimensional structure is represented in a circumplex model with eight sectors. Using Smallest Space Analysis (SSA), this study examined the circumplex structure of the Chinese version of the QTI among a convenience sample of 731 primary-school students in Hong Kong. The study revealed that the SSA solution fits the circumplex structure of the Model for Interpersonal Teacher Behavior and uncovered a two-dimensional solution yielding five sectors in a clockwise direction: Strict, Leadership-Helpful/Friendly-Understanding, Student Responsibility/Freedom, Uncertain, and Admonishing-Dissatisfied. While the Leadership-Helpful/Friendly-Understanding sector was the largest, the Student Responsibility/Freedom sector was the smallest, with few items constituting it. For the two dimensions, the vertical dimension was named Structure Clarity, with adherence to external structure (Strict sector) at one extreme and lack of structure (Uncertain sector and Student Responsibility/Freedom sector) at the other extreme. The horizontal axis was labelled Attitude Valence, with benevolent valence (Leadership sector, Helpful/Friendly sector and Understanding sector) at one end and malevolent valence (Admonishing sector and Dissatisfied sector) at the other end of the axis. The positioning of the five sectors in the present study is in line with the factor structure that was often found in previous research on the circumplex model. By presenting a somewhat different interpretation of the two dimensions and some additional items, we hope that future research will verify our suggestions across different sociocultural settings. 相似文献

This article reports the results of an experimental study of the effects of students' evaluative feedback to university instructors. Data obtained indicated that feedback from students did not have any significant effects on the instructors' teaching performance and their perception of teaching. Some limitations of the study are discussed with suggestions for further exploration of the problem. 相似文献
