论行政执法中的的法律价值观冲突

行政执法人员的法律价值观是行政执法行为的思想基础和行为依据,直接影响着法律执行的价值状态。行政执法中的法律价值观冲突严重影响着价值观功能的发挥,制约着行政执法的效果。必须强化行政执法人员的法律信仰,确立解决行政执法中法律价值观冲突的基本准则。     

Comparison of two methods for isolating DNA from human skeletal remains for STR analysis

Abstract: The quality and efficiency of a standard organic DNA isolation method and a silica‐based method using the QIAGEN Blood Maxi Kit were compared to obtain human DNA and short tandem repeats (STRs) profiles from 39 exhumed bone samples for paternity testing. DNA samples were quantified by real‐time PCR, and STR profiles were obtained using the AmpFlSTR^® Identifiler^® PCR amplification kit. Overall, the silica‐based method recovered less DNA ranging from 0 to 147.7 ng/g (average 7.57 ng/g, median = 1.3 ng/g) than did the organic method ranging from 0 to 605 ng/g (average 44.27 ng/g, median = 5.8 ng/g). Complete profiles (16/16 loci tested) were obtained from 37/39 samples (95%) using the organic method and from 9/39 samples (23%) with the silica‐based method. Compared with a standard organic DNA isolation method, our results indicate that the published silica‐based method does not improve neither the quality nor the quantity of DNA for STR profiling.

Secrecy and Self-Interest: When Mediators Act Deceitfully

3rd party intervention in interstate conflict is a common strategy for mitigating conflict and obtaining a final agreement. However, not all mediations are successful, leading to the development of a rich literature on the mechanisms which decrease the probability of failure in a 3rd-party intervention. Within this literature, some studies examine how a mediator’ behavior and incentives affect the result of the mediation. Virtually all these studies assume that the mediator is virtuous such that peace is the most desired outcome of a conflict for her. However, this study challenges this assumption and contends that a mediator can gain benefit from the conflict between disputants. If this benefit is adequately large to overcome the benefits of peace, then the mediator has enough incentive not to conduct the mediation toward a peaceful outcome. We develop a signaling game model to study this issue formally and test the proposed hypothesis empirically.     

高铜对雏鸭肝影响的病理学观察

将360只1日龄天府肉鸭随机分为6组,分别喂以对照日粮(Cu 8 mg/kg)和高铜日粮(Ⅰ组:Cu100 mg/kg;Ⅱ组:Cu 200 mg/kg;Ⅲ组:Cu 400 mg/kg;Ⅳ组:Cu 600 mg/kg;Ⅴ组:Cu 800 mg/kg)6周,研究日粮铜添加水平对雏鸭肝及其相关生化指标的影响。结果显示,Ⅱ组、Ⅲ组、Ⅳ组、Ⅴ组雏鸭肝出现不同程度的病理损伤,肝细胞颗粒变性、空泡变性。Ⅳ组、Ⅴ组肝铜含量和血清铜含量均显著高于对照组(P<0.01)。Ⅲ组、Ⅳ组和Ⅴ组血清丙氨酸氨基转移酶、天门冬氨酸氨基转移酶活性显著升高(P<0.01)。结果表明,日粮铜含量达400~800 mg/kg即可引起肝的病理损伤。     

江苏省猪高热病病例主要继发感染病毒的多重PCR检测

应用建立的2个多重PCR方法,对2005~2006年收集于江苏省的211份猪高热病疑似病料进行了检测。结果,PRRSV阳性率为51.2%,PCV2阳性率为44.1%,CSFV阳性率为10.4%,PPV阳性率为3.9%,PRV阳性率为2.4%。2005年病料中PCV2阳性率为21.2%,2006年为73.2%;2005年PRRSV阳性率为38.1%,2006年为67.7%。2006年猪高热病疫情比2005年严重,PCV2和PRRSV可能在其中发挥了协同致病作用。对10个PRRSV分离株ORF5基因和Nsp2基因进行的测序表明,2006年分离株Nsp2基因中有连续87个碱基的缺失。

E‐government and public service quality in Ghana

This article contributes to the growing discourse on the potential of e‐government to transform the operations of public sector institutions, thereby improving public services. It does so by conceptualizing public service quality into efficiency, economy (cost reduction), customer satisfaction, and service accessibility and draws on qualitative data from the Ghanaian narrative for illustration. As previous studies have demonstrated, this study also affirms the potential of e‐government in improving public services delivery by increasing efficiency, reducing the cost of operations, expanding access to services, and achieving customer satisfaction. Yet, there remains a repertoire of challenges such as weak ICT infrastructure especially in towns and villages, incessant power outages and illiteracy, which are drawbacks to fully harnessing the benefits of e‐government in Ghana. The study recommends that these challenges should feature prominently in e‐government policies to increase the chances of solving them.     

The structure of foreign policy attitudes in transatlantic perspective: Comparing the United States,United Kingdom,France and Germany

While public opinion about foreign policy has been studied extensively in the United States, there is less systematic research of foreign policy opinions in other countries. Given that public opinion about international affairs affects who gets elected in democracies and then constrains the foreign policies available to leaders once elected, both comparative politics and international relations scholarship benefit from more systematic investigation of foreign policy attitudes outside the United States. Using new data, this article presents a common set of core constructs structuring both American and European attitudes about foreign policy. Surveys conducted in four countries (the United States, the United Kingdom, France and Germany) provide an expanded set of foreign policy‐related survey items that are analysed using exploratory structural equation modeling (ESEM). Measurement equivalence is specifically tested and a common four‐factor structure that fits the data in all four countries is found. Consequently, valid, direct comparisons of the foreign policy preferences of four world powers are made. In the process, the four‐factor model confirms and expands previous work on the structure of foreign policy attitudes. The article also demonstrates the capability of ESEM in testing the dimensionality and cross‐national equivalence of social science concepts.     

The Penal Voluntary Sector in England and Wales: Adaptation to Unsettlement and Austerity

This article draws on some findings from research which investigated penal voluntary sector adaptation to the mixed market in criminal justice services. The article firstly reprises the main trends for aligning state relationships with the voluntary sector from the 1980s to the present. We then outline some findings about adaptive experiences, situations and practices of the voluntary sector in criminal justice resettlement in the light of considerable upheaval. The research found that service providing voluntary sector organisations (VSOs) either outwardly comply with, or, in a minority of cases, actively embrace, competitive marketised models of service delivery. Secondly, the sector has normalised commercial approaches to organisational efficiency as well as aligned with bureaucratic practices common to the statutory sector. Despite charges that they are effectively co‐opted by both state and market interests, many have reported conflicts between prioritising long‐term financial viability with their founding ‘ethos and values’. We conclude that while many VSOs have successfully adjusted to market and bureaucratic norms, aspects of that repositioning have been at a cost to their traditions of relative autonomy, localism and distinctiveness, to the possible detriment of a vigorous civil society.
