Discrimination of phenethylamine regioisomers and structural analogues by Raman spectroscopy

In this study, the Raman spectra of 21 phenethylamines were obtained using far‐red excitation (785 nm). The distinguishing ability of Raman for phenethylamines, especially for phenethylamine regioisomers and structural analogues, was investigated. Here, the evaluation of a cross section of Raman spectra demonstrated that all types of phenethylamines were distinguishable, even for certain structural analogues with high spectrum similarity. Raman exhibited high distinguishing ability for phenethylamine regioisomers that differ in the substitution position of halogen, methoxy, alkyl, or other substituted groups; as well as for structural analogues containing different groups, such as furanyl, 2,3‐dihydrofuranyl, halogen, and alkyl substituted at the same position. The Raman spectra for homologues with differences in only a methyl group were found to be highly similar; however, their spectra demonstrated small but detectable differences. Four analogue mixtures and 59 seized samples were also analyzed to study the practical use of the Raman method in forensic field. 95% of the seized samples were correctly identified, which significantly validated the ability of Raman method in identifying the correct isomers. Accordingly, this study provides a non‐destructive, high‐throughput and minimal sample preparation technique for the discrimination of phenethylamines.     

Irony Practice: Reconstructing Structural Social Work: Enlightenment from Neoclassical Sociology

Structural social work has been expanding its influence while experiencing marginalized crises since 1970s: with the expansion of neo-conservatism, the structural perspective is incompatible with the liberal-based system at the political level. In recent years, the “critical reflection practice” established through the reunification of the socialist tradition of social work has become increasingly prosperous, but it has not been possible to answer the question of legitimacy in its own theory. The purpose of this paper is to reflect the crisis of the traditional sociology by analyzing the crisis of western sociology, and to try to reconstruct the critical social science by talking with Iván Szelényi and others to sort out the concept of “irony” as a methodology and the mission of contemporary intellectuals. Under the inspiration of relevance of classical sociology and social work, this paper provides insights to the reconstruction of social work.     

Establishing a Social-Darwinist Mentality in Japan’s Paternalist State: The Potential of Resistance by a Counter-Public

ABSTRACT

From a historical perspective, the welfare net in Japan was established from above without democratic participation and expanded only slowly. This expansion in many cases was aimed at enhancing national cohesion, especially during war time. During the current neoliberal era, Japan’s paternalistic welfare state has been able to put into practice the dismantling of national pension and health-care systems without the need for any theoretical re-orientation. In response, counter-publics have engaged in protest and resistance. By doing so, the victims of modernization and those who are socially weak and disadvantaged in multiple ways are able to regain their self-esteem and personal integrity.     

Juvenile Desistance and Community Disadvantage: The Role of Appropriate Accommodations and Engagements

In recent years, juvenile justice systems have shown renewed interest in ensuring effective programming and support for young offenders as they reenter the community. These services often focus on suitable accommodations, education, work-based employment, and engagement in conventional activities. Recent studies also suggest, however, that these services may not have the desired impact in the community (i.e. desistance) if underlying community-level risk factors are not attended to. This may especially be the case for young offenders. Given the developmental literature underscoring the heightened sensitivity of youth to external conditions, this study focuses attention on the recidivism of young offenders in the United Kingdom. Data from 2005 through 2009 show that changes in appropriate accommodation and engagement offered to ex-offenders in a community are both related to a community’s rate of youth reoffending; however, the strength of this relationship differs across level of community disadvantage.     

我国外贸依存度的结构性特征

外贸依存度高已经成为我国发展对外经济面临的一个突出问题。总体上看,我国外贸依存特征为外贸依存地区、国家集中,外贸依存东高西低,一般贸易外贸依存度上升、但加工贸易依存度依然偏高,附加值低的劳动密集型产品的外贸依存度高,对资源的进口依赖度高,对高技术装备和核心技术的进口依赖高等。研究我国外贸依存度的这些结构性特征,要有针对性地采取应对措施。     

Russia’s economic policy in 2015–2016: the imperative of structural reform

In the aftermath of the global economic crisis, we have seen uneven development in the leading advanced and emerging economies, new models of economic growth that vary from country to country, uncertain prospects for globalization and challenges of “regional globalization,” looming currency re-configurations, as well as shifting energy price dynamics and their influence on political and economic prospects of particular states. This paper discusses current challenges for social and economic policy in the context of the history of the past 30 years. With reference to Russia, it focuses on a new growth model, structural transformation (including import-substitution issues), economic dynamics, fiscal and monetary concerns, and social issues. It concludes by addressing the priorities of economic policy.     

Unemployment, Economic Theory, and Property Crime: A Note on Measurement

Drawing on rational choice theory, this study considers how best to measureunemployment within the context of the unemployment–property crimerelationship. Specifically, we use ARIMA techniques to examine the relativeefficacy of using the conventional Bureau of Labor Statistics (BLS)unemployment rate and two alternative measures of the demand for labor aspredictors of monthly counts of U.S. property offenses for the years 1982through 1996. The bivariate time series analyses indicate that while theBLS unemployment rate exhibits null effects, the number of individualsunemployed for 15 weeks or more and the capacity utilization ratesignificantly affect the level of property crime. The implications ofthese results are discussed.     

牛趋化因子受体4基因的克隆表达及序列分析

采用RT-PCR技术,从被刺激诱导的牛外周血单个核细胞(PBMC)中克隆了牛趋化因子受体4(CXCR4)全长基因,并将CXCR4基因和CXCR4基因N端1～126 bp(CXCR4~(42aa))片段分别亚克隆到原核表达载体pGEX-4T-1中,命名为pGEX-4T-1-CXCR4、pGEX-4T-1-CXCR4~(42aa).获得重组菌株后,采用不同的IPTG浓度、不同诱导时间、不同温度和不同培养基等组合诱导表达这两种重组菌,其中pGEX-4T-1-CX-CR4~(42aa)重组菌获得了表达,并在37℃、IPTG浓度为0.8 mmol/L、诱导6 h时表达量最大,约占菌体总蛋白的45%,目的蛋白主要以包涵体的形式存在;而pGEX-4T-1-CXCR4重组菌未表达出目的蛋白.     

Tussle for space: The politics of mock-compliance with global financial standards in developing countries

As efforts to harmonize policies globally intensify, developing countries increasingly face pressures to adopt international standards. Yet, we know little about the circumstances under which developing countries manage to circumvent such pressures, or about their strategies to maintain policy space. We explore under which conditions developing countries are willing and able to sustain mock-compliance, a situation where countries comply on paper but not in practice. Using country comparisons of Angola's, Nigeria's, Tanzania's, and Vietnam's engagement with the Basel banking standards, we show how three factors combine to produce sustained mock-compliance: high costs of outright non-compliance due to outward-orientated banking sectors; high political costs of substantive compliance; and state control over profitable markets. Our article contributes to theory-building in the literature on compliance and structural power as well as to broader debates about developing countries' policy autonomy in their engagement with global financial norms.     

新旧矛盾、结构矛盾及其关系

新旧矛盾是事物内部新的一方与旧的一方组成的矛盾,其主要特征是相克,在事物发展的质变阶段表现比较突出;结构矛盾是事物内部不同部分、层次之间组成的矛盾,其主要特征是相生,在事物发展的量变阶段表现比较突出。两类矛盾相互交织,相互转化,共同推动着事物的运动和发展。实践中,要正确认识两类矛盾,用不同的思维方式解决不同的矛盾,同时,思维方式还要随矛盾的变化而变化,要注重两种思维方式的有机结合,只有这样,对构建和谐社会才有现实的指导价值。
