随着世界进入"环保时代",绿色贸易壁垒法律制度对一国的经济贸易的影响越来越突出和重要,面对我国绿色贸易壁垒法律制度立法、执法、司法绩效不容乐观的情况,以新制度经济学的制度绩效为主要的理论基础,设立我国绿色贸易壁垒法律制度的性能评价体系,能够为我国绿色贸易壁垒法律的制度设计和实践操作开创定量评判的崭新标准。  相似文献

我国立法采用了国际上通行的以意思自治为主、最密切联系为辅的涉外民商事合同法律适用原则,但该原则在我国<民法通则>和<合同法>中的规定过于简单,缺乏可操作性.自2007年8月8日起施行的<最高人民法院关于审理涉外民事或商事合同纠纷案件法律适用若干问题的规定>弥补了现行立法的不足.该司法解释针对涉外民商事合同审判实践中经常遇到、存在异议的问题.提出了明确的处理意见.通过对该司法解释中特征性履行方法和外国法的查明等靓点的分析,认为该规定在支配当事人选择法律的效力、当事人选择法律的方式、当事人选择法律的范围、禁止法律规避之规定、保护弱方当事人利益等方面仍存在不足之处,需要加以完善.  相似文献

Based on a novel data set that links college administrative information with earnings records from a state college system for both public two‐year and four‐year colleges, this study quantifies the impacts of exposure to different types of instructors during students’ initial semester in college on their subsequent academic and labor market outcomes. To minimize bias from student sorting by type of instructor, we combine course‐set fixed effects with an instrumental variables approach that exploits term‐by‐term fluctuations in faculty composition in each department, therefore controlling for both between‐ and within‐course sorting. The findings suggest that two‐year students, particularly racial minority students, have substantially higher levels of exposure to adjuncts with temporary appointments than four‐year students. Two‐year students taking a heavy course schedule with temporary adjuncts are adversely affected in college persistence and subsequent credit accumulation, and the penalty is particularly pronounced among males and racial minority students with stronger academic potential. Such negative impacts on academic outcomes do not translate into poorer short‐ to medium‐term labor market performance. In the four‐year setting, no significant distinction is identified between different types of instructors on either student academic or labor market outcomes.  相似文献

The article reviews the evidence about success of public sector reforms in low and middle income countries, external support for such reforms, and recent ideas of how such support could be better designed and implemented. Enthusiasm for supporting public sector reforms has decreased over the past decade, and available data suggest that there has been little overall improvement. However, it also indicates that a small number of countries have significantly strengthened their public sectors over the past 10 to 20 years. The article then reviews five new approaches that have been proposed for better supporting public sector reforms. It looks at how they diagnose what has not worked and the implications of what should be carried out differently. Furthermore, it explores to what extent the available evidence of overall stagnation as well as of success cases fits with these proposed alternatives, to gauge to what extent they are likely to make a difference. The final section sets out the implications. Development agencies should seek to deliberately test a combination of the proposed alternative approaches, particularly in more difficult contexts, taking political feasibility as a basis and adding other elements. The urgency to make progress remains high. Copyright © 2016 John Wiley & Sons, Ltd.  相似文献

ABSTRACT

The social practice of reading aloud picture books to children, or shared reading, has been represented on many televisions programmes broadcast across English-speaking countries. This article views shared reading as a performance, and explores its transformation on two television shows for children and the potential of such shows to promote reading engagement and literacy development. Taking a critical multimodal perspective, we analyse shared reading in real life and on television as a social practice, focusing on the ways the participants talk about the picture book, relate it to exterior texts or activities, and legitimise shared reading through the employment of multimodal and interactive strategies. The analysis reveals significant differences between actual adult–child shared reading and its representation on television. The comparison illustrates the potential benefits and limitations of television shows in which picture books are read to the viewer, in terms of promoting shared reading among families and supporting young children’s emergent literacy development.  相似文献

The illegal use of formalin (commercial formaldehyde) in cosmetic products harms the health of individuals exposed to this substance. Over the last years, the commercial availability of these products, especially those containing irregular dosage of formaldehyde, has increased in Brazil. This work analyzes some products for hair treatment available in the Brazilian market and verifies their safety. The adopted analytical methodology involved sample derivatization with 2,4‐dinitrophenylhydrazine, followed by high‐performance liquid chromatography with ultraviolet detection (UV–VIS) at λ = 365 nm. The limit of quantification is 2.5 × 10?3% w/w, and the recovery tests were around 93%. Some of the samples contained high and illegal formaldehyde levels ranging from 9% to 19% (w/w) and others presented suitable concentrations of the analyte. On the basis of the results, this work discusses the efficiency and practicality of this analytical method for forensic purposes.  相似文献

The authors are exploring degradation patterns of latent fingermarks over time which can be quantitatively determined in a predictable manner by visual means. Several physical degradation parameters for assessing this hypothesis are evaluated. This article analyzes the parameter “minutiae count” as a function of time. Experiment variables included were secretion type (sebaceous‐rich and eccrine‐rich), substrate (glass and plastic), and exposure to light (dark, shade, and direct light). Depositions were sequentially visualized with Titanium Dioxide powder over a period of 6 months, photographed, and number of minutiae recorded. Results revealed a significant decrease of minutiae for eccrine‐rich marks on glass but insignificant for sebaceous‐rich marks on the same surface. However, significant degradation was observed for both types of secretions on plastic. The authors conclude that the distinctive prevalence of minutiae changes over time indicates with a high degree of certainty the hypothesis is valid and deserves additional exploration.  相似文献

Opium is the raw material for the production of heroin, and the characterization of opium seizures through laboratory analysis is a valuable tool for law enforcement agencies to trace clandestine opium production and trafficking. In this work, a method for opium profiling based on the relative content of five principal and 14 minor opium alkaloids was developed and validated. UPLC‐Q‐TOF was adopted in alkaloid analysis for its high selectivity and sensitivity, which facilitated the sample preparation and testing. The authentic sample set consisted of 100 “Myanmar” and 45 “Afghanistan” opium seizures; based on the data set of the 19 alkaloid variables in them, a partial least squares discriminant analysis classification model was successfully achieved. Minor alkaloids were found to be vitally important for opium profiling, although combined use of both principal and minor alkaloids resulted in the best geographical classification result. The developed method realized a simple and accurate way to differentiate opium from Myanmar and Afghanistan, which may find wide application in forensic laboratories.  相似文献

This article undertakes an auto-critical analysis of the research team's ethnographic study of Cultural Enterprise Office (CEO), a Scottish creative business support agency. We discuss the team's composition and how this relates to other analyses of ethnographic teamwork. Our research is situated in the wider policy context of the “creative-economic” turn in the UK's research funding. This has been accompanied by increased emphasis on “knowledge exchange” and “impact” in the drive for greater accountability in higher education. The team's evolution in the course of undertaking research is illustrated by reference to four “pivotal moments,” which illustrate how we “performed” knowledge exchange.  相似文献
