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

Abstract

To date, Latvia's student corps have remained a neglected topic in the country's political history, notwithstanding the size of these organisations and the fact that they have been in existence for more than a century. Those accounts that do exist have for the most part been written by corps members themselves, and have not included any real analysis of the corps' interaction with society or their role in Latvian political life. A study of these issues opens up new avenues towards a better understanding of the activity and influence of interest groups in Latvian politics during the 1920s and 1930s. Unlike many other social organisations, the student corps (also including the alumni societies) are often seen as linked to the activity of the major parties, to the coup d'état of 1934 and to radical Latvian nationalism.  相似文献

The present study examined the effects of institutional pressures on homeland security preparedness among law enforcement agencies in Illinois. The data come from the Illinois Homeland Security Survey (IHSS). Specifically, the study employed three theories to explain homeland security preparedness: contingency theory, resource dependence theory, and institutional theory. We hypothesized that institutional pressures will lead to isomorphism as agencies attempt to conform to institutional expectations about appropriate activities in a homeland security era. To evaluate these theories and their impact on homeland security practices, the authors used confirmatory factor analysis. The IHSS data lend strong support to the application of organizational theory as a lens through which homeland security preparedness can be understood. Institutional pressures, such as professional and government publications, training, professional associations, and the actions of peer agencies, significantly influenced municipal and county agencies in Illinois. Funding, while often thought important to encourage preparedness, was not a significant predictor. The results of this analysis advance our understanding of homeland security preparedness via institutional theory by suggesting that the larger environment is salient.  相似文献

The transfer of DNA from hands to objects by holding or touching has been examined in the past. The main purpose of this study was to examine the variation in the amount of DNA transferred from hands to glass, fabric and wood. The study involved 300 volunteers (100 for glass, 100 for fabric and 100 for wood) 50% of which were male and 50% female. The volunteers held the material for 60 s. The DNA was recovered from the objects using a minitape lift, quantified using the Quantifiler kit assay, extracted using a ‘Qiagen® QIAamp DNA mini kit’ and amplified using the AmpFlSTR® SGM Plus™ Amplification Kit at 28 cycles. The results show that using ANOVA there was a significant difference (F = 8.2, p < 0.05) between the three object types in the amount of DNA recovered. In terms of DNA transfer and recovery, wood gave the best yield, followed by fabric and then glass. The likelihood of success of obtaining a profile indicative of the holder was approximately 9% for glass samples, 23% for fabric and 36% for wood. There was no significant difference between the amount of DNA transferred by male or female volunteers. In this study good shedder status, as defined by obtaining useful profiles of 6 or more alleles, is estimated at approximately 22% of the population. The phenomenon of secondary transfer was observed when mixed DNA profiles were obtained but the incidence was low at approximately 10% of the total number of samples. DNA profiles corresponding to more than one person were found on objects which had been touched by only one volunteer. Although secondary transfer is possible the profiles obtained from touched objects are more likely to be as a result of primary transfer rather than a secondary source.  相似文献

“Touch DNA” is a form of trace DNA that is presumed to be deposited when an individual touches something and leaves behind DNA-containing skin cells, sweat, or other fluids. While touch DNA is often the result of direct contact (i.e., primary transfer), it can also be indirectly transferred between surfaces or individuals (e.g., secondary or tertiary transfer). Even experts cannot distinguish between different types of transfer and do not fully understand which variables affect direct versus indirect transfer or how often each type of transfer occurs. In this study, we utilize an innovative protocol that combines a paired male and female transfer DNA experimental design with an Amelogenin qPCR assay to generate data on primary, secondary, and tertiary DNA transfer. We report frequencies of indirect DNA transfer and also investigate the potential effects of participant age, self-identified ethnicity, and skin conditions on DNA transfer. Out of 22 experimental trials, we detected primary transfer (male + female) in 71% of trials, secondary DNA transfer in 50% of trials, and tertiary DNA transfer in 27% of trials. No significant associations were found between primary DNA transfer and age, self-identified ancestry, or skin conditions, however, all individuals with sloughing skin conditions demonstrated primary DNA transfer and we suggest this variable be explored in larger samples. These results contribute to a better understanding of the conditions under which secondary and tertiary DNA transfer occurs and can be used to propose realistic DNA transfer scenarios in court cases.  相似文献

The ability to detect low level DNA brings with it the uncertainty of whether the detected DNA is a result of transfer. To address this uncertainty, a simulation study was conducted in which a mock illicit drug packet was placed into the personal bags of individuals. When the average transit time of the packets was increased from around 2 h to more than 14 h, the percentage of the DNA profiles recovered from the packets which could be attributed to the individuals increased greatly from 5.3% to 48.6%. We found that drug packers who were poor shedders could not be included as contributors to the DNA profiles from the drug packets at all and there was a higher chance that individuals other than themselves could be included as contributors to the DNA profile recovered from drug packets. We also found that it was equally likely that the drug packers who had direct contact with the drug packets and bag owners who did not, could be included as contributors to the DNA profiles recovered from the packets. The results in this study highlight the importance of taking into consideration the transit time of drug packet, the shedder status of the alleged packer and the history of an item, when evaluating DNA evidence in the context of illicit drug activities.  相似文献

政府数据在法律性质上具有财产的属性,在实践中也具有可交易性的特点,是一种财产性权利。政府数据开放具有渐进性、开放性、价值性、时效性、周期性、非买断性和再利用性的特点,根据不同的标准可对其作相应的类型化区分。政府对于开放的数据进行收费定价有其合理基础,在数据开放定价模式上则有免费模式、按成本费用定价模式以及按“成本+利润”定价模式。我国政府数据开放的定价收费问题,应置于行政收费的法制框架下讨论,基于公平、效率和量能支付等行政收费的基本原则,确立向社会公众免费开放、向市场主体的商业化利用有限收费的制度。作为减损公民财产利益的负担行为,政府数据开放收费定价应受到法律的严格规制。在确立政府数据开放的基本定价模式基础上,由立法来创设数据的收费定价,完善收费程序,加强对收费定价行为的行政内部监督机制建设,从而推动政府数据有序、规范开放。  相似文献
