The enforcement behaviour of environmental officials in developing countries has not received adequate attention despite enormous challenges to regulatory enforcement in those areas. Accordingly, this article examines the relationship between perceptions of support from local governments and society and evaluations of enforcement effectiveness. A model in which organisational commitment partially mediates these relationships was tested using a sample of 202 enforcement officials in Guangzhou, China. The findings confirm a partial mediating role for organisational commitment and an interaction effect between government and societal support. A plot of this interaction reveals that when enforcement officials perceive high levels of governmental support, societal support further enhances their perceptions of enforcement effectiveness. However, when they perceive government support to be low, higher levels of societal support appear to diminish their assessments of enforcement effectiveness.  相似文献

There is a world of difference between teaching negotiation theory, which pertains to conceptual understanding, and teaching negotiation skills, which pertain to actual behavior in real‐world situations. The principle of reflective practice is widely used for theoretical instruction. Deliberate practice, however, is a more powerful model for skills training. Cognitive scientists have discovered that subjects will learn skills best when they perform well‐defined tasks at appropriate levels of difficulty, and when they are given immediate feedback, an opportunity to correct their errors, and an opportunity to practice until the tasks become routine. To satisfy the deliberate practice conditions for large graduate‐level negotiation courses (some as large as seventy students), students were assigned to use webcams with their laptop computers to video record their negotiation exercises. Before each exercise, students were assigned to prepare for and to concentrate on performing two or three well‐defined tasks. Students reviewed these recordings and commented on their performances in a journal before uploading the videos and journals to an assigned network folder. The instructor and teaching assistants then reviewed the journals and specified portions of the videos and provided individual written feedback to the students. The instructors found that student negotiating skills have improved significantly using this new system. In comparison with earlier semesters, students also felt they were involved in a more intense and personal learning experience. A majority of students reported they intend to apply the principles of deliberate practice in their professional lives after graduation. The authors have found this method continues to challenge their ability to identify and describe the skills used by expert negotiators. As an addition to this new methodology, two of the authors have spearheaded the development of video annotation software, known as “MediaNotes,” to help students and instructors review, comment upon, and learn from video recordings of negotiations. Based on their experiences using the software to support deliberate practice, the authors expect this tool to initiate a significant advance in our ability to recognize and describe expert negotiation behavior and in students’ ability to improve their negotiating skills.  相似文献

Canada has been a world leader in administrative reform, eager to experiment during turbulent times in public administration. Public Service 2000, an attempt to instill the Canadian public service into a people- and results-oriented management culture, has been widely heralded as among the boldest of recent Canadian administrative reforms. Results from implementing PS2000 were expected within a decade of its 1990 launch. Halfway through that timeframe, the results are surprising, complex, contradictory and paradoxical. For example, in the second year of implementation, the longer term solutions of PS2000 conflicted with a financial crisis demanding fast results, and PS2000 principles, throughout implementation, contradicted certain traditional public service values. Reflecting on their experience, individuals who participated in PS2000 confirmed lessons in the extant literature, and suggested lessons specific to Canadian circumstances. PS2000 has been an unavoidable and much-needed effort to reform the Canadian public service, though perhaps inevitably it fell short of expectation. Yet, inside opinion remains mixed, seeking rationalist explanations, and expressing dissatisfaction over the progress of implementation. PS2000 has been absorbed into a much broader plan to reinvent federal government administration and the role of the state in Canadian society. Continuing difference of opinion may well call for a more fundamental change in administrative and managerial doctrine, especially with respect to launching future comprehensive administrative reform projects.  相似文献

The market is inundated with inkjet printers, laser printers, and photocopiers, which are often used in criminal activities. Many of these office machines are built by various manufacturers, hence they are constructed with different hardware designs (e.g. "rolling" and "grabbing" mechanisms) that have changed over the years due to technological advances. Examinations of printed documents that involve the chemical analysis of ink colorants and the identification of physical machine defects such as trash marks are essential for the forensic examiner, but new techniques are needed to more closely identify a machine model or group of models. An electrostatic detection device (EDD) provide forensic examiners with a nondestructive method to examine indentations on a document. In this work, an EDD is used to detect latent physical markings left on documents by printers and photocopiers. Seventeen inkjet printers, 12 laser printers, and 3 photocopy machines were used to produce test documents. Physical markings were detectable in the large majority of the documents and were reproducible 100% of the time.  相似文献
