我国技术转让过程中存在着信息占有方未进行信息披露、披露不充分以及虚假披露等主要问题,严重影响到我国技术市场的健康发展。为此,我国应以完善信息披露制度立法为主要路径,强制信息占有方披露重要信息并规范其披露行为,建立和完善相应的市场配套机制,这样方能减少信息披露引发的技术交易纠纷。  相似文献

Equipment for annealing casework sized glass particles is described. Investigations were carried out using a simple muffle furnace, a temperature programmed furnace and a metal sample holder. Because they produced a uniform and reproducible thermal environment, best results were obtained from a combination of the temperature programmed furnace and the metal sample holder. Refractive index changes for window and toughened glass specimens were investigated and a simple, reproducible annealing routine for casework was devised.  相似文献

The microscopical examination of original surfaces on casework sized glass particles using an interference objective and the interpretation of their interferograms is discussed. To reduce subjectivity, a numerical criterion was devised to assess the curvature of glass particles and this was then applied to a survey of window, container, tableware and vehicle glasses. Objects with curved surfaces produced particles that were distinctly curved while those from surfaces of both modern and old windows were clearly identifiable as flat. Apparently flat surfaces from tableware and containers almost always yielded specimens that were detectably curved. In addition, there was no evidence that a fracture surface would be confused with an original surface from a plain flat glass.In a ‘blind’ trial to assess the interferometric routines, three examiners correctly identified flat and curved surfaces on 15 particles derived from a selection of glass objects.  相似文献

The Scent Transfer Unit (STU-100) is a portable vacuum that uses airflow through a sterile gauze pad to capture a volatiles profile over evidentiary items for subsequent canine presentation to assist law enforcement personnel. This device was evaluated to determine its ability to trap and release organic compounds at ambient temperature under controlled laboratory conditions. Gas chromatography-mass spectrometry (GC-MS) analyses using a five-component volatiles mixture in methanol injected directly into a capture pad indicated that compound release could be detected initially and 3 days after the time of collection. Additionally, 15 compounds of a 39-component toxic organic gaseous mixture (10-1000 parts per billion by volume [p.p.b.(v)]) were trapped, released, and detected in the headspace of a volatiles capture pad after being exposed to this mixture using the STU-100 with analysis via GC-MS. Component release efficiencies at ambient temperature varied with the analyte; however, typical values of c. 10% were obtained. Desorption at elevated temperatures of reported human odor/scent chemicals and colognes trapped by the STU-100 pads was measured and indicated that the STU-100 has a significant trapping efficiency at ambient temperature. Multivariate statistical analysis of subsequent mass spectral patterns was also performed.  相似文献

In recent years, development agencies (DAs) have focused their activities on consulting projects rather than on financing turnkey projects when assisting emerging markets. The main reason is that the implementation of consulting projects is likely to be connected with an intensive knowledge transfer from developed to emerging markets. Training of local employees and cooperation with local firms are necessary elements to make the transfer effective. The empirical statistics shows training and cooperation to be more frequent in consulting projects financed by DAs as compared to commercial projects. According to theory and experience, training should be included in projects in the least developed host countries, whereas local cooperation should be more frequent, the higher is the development level of the host country. However, DAs do not follow these rules of thumb in a convincing way. A policy implication of the paper is therefore that DAs should better organize and plan the contents of their consulting projects.

Despite the immense popularity of offender profiling as both a topic of fascination for the general public as well as an academic field of study, concerns have been raised about the development of this area of scientific inquiry. The present study provides a preliminary step towards moving the field forward as it reviews the type and quality of studies dealing with offender profiling over the past 31 years. Based on a content analysis of 132 published articles, the review indicates that researchers investigating this phenomenon rarely publish multiple articles, and they are generally reported across many different journals, thereby making knowledge synthesis and knowledge transfer problematic. In addition, the majority of papers published in the area are discussion pieces (e.g., discussing what profiling is, how profiles are constructed, and when profiling is useful), despite the fact that the processes underlying offender profiling are still not well understood. Finally, although peer-reviewed articles exploring this topic have steadily increased, the statistical sophistication of these studies is sorely lacking, with most including no statistics or formal analyses of data. Suggestions for future research and recommendations to streamline efforts in this field are provided based on the results of this review.

The present study aims to contribute to the existing policy transfer research by examining the immature policy environments of post‐communist countries. To determine the main factors explaining the process of policy transfer, the establishment of probation systems in Estonia and Latvia is analyzed by applying a comparative case study design. The study demonstrates that timing is an important variable in the policy transfer in a transitional setting. A transitional context in itself is likely to lead to policy transfer because of urgent decision‐making needs, a shortage of domestic expertise and of financial resources. The process of policy transfer can be characterized as quite fortuitous: the choice of role models is limited to the existing or first contacts with foreign partners who are able to provide financial assistance. Improvement of administrative capacity is seen as a key factor in the shift from haphazard policy copying to responsible policy transfer. Copyright © 2012 John Wiley & Sons, Ltd.  相似文献
