法治的实现目标及其途径

法治社会的价值目标是追求民主、平等;法治的核心问题是约束、限制权力;法治国家的本质特征是体现民治;实现 法治化的基本途径是建立安全、方便、经济的参政方式。     

三株鸭源H9N2亚型禽流感病毒福建株全基因的测序及遗传进化分析

为明确3株鸭源H9N2亚型禽流感病毒福建株A/Muscovy duck/Fujian/CL/1997(H9N2)(简称CL株)、A/duck/Fujian/MH/2003(H9N2)(简称MH株)和A/duck/Fujian/FQ2/2007(H9N2)(简称FQ2株)全基因组的分子特征和遗传进化情况,采用RT-PCR方法扩增这3株病毒全基因片段,并进行序列比较及遗传进化分析。结果表明,所克隆的8个基因片段均有完整的开放阅读框,其血凝素基因蛋白裂解位点的氨基酸组成为-RSSR*GLF-,为不连续的碱性氨基酸,其静脉接种指数远小于1.2,均符合低致病性AIVHA蛋白裂解位点特征;CL株和MH株的HA基因在遗传进化上属于常见的CK/BJ/1/94群系;FQ2株HA基因在遗传进化上属于DK/HK/Y280/97群系,3株H9N2亚型AIV HA基因在遗传进化上均属于经典的欧亚种系。3株H9N2亚型AIV NA基因颈部均存在缺失,CL株和MH株的NA基因在遗传进化上属于常见的CK/BJ/1/94群系,FQ2株NA基因在遗传进化上属于G1群系。CL株和MH株的其他6个基因在遗传进化上均和经典的CK/BJ/1/94一致,而FQ2株则可能是由不同流感病毒基因亚系间发生自然重排的产物。     

猪繁殖与呼吸综合征病毒重组质粒pEGFP-NSP9的构建与表达

为验证siRNAs对猪繁殖与呼吸综合征病毒复制的抑制效果,构建了猪繁殖与呼吸综合征病毒NSP9基因与增强型绿色荧光蛋白基因GFP的融合表达质粒,并在Marc145细胞中进行了表达。通过RT-PCR方法扩增猪繁殖与呼吸综合征病毒NSP9基因,将其克隆入表达载体pEGFP-N1,并进行双酶切、PCR及测序鉴定。将阳性重组质粒转染Marc145细胞,检测绿色荧光蛋白的表达和NSP9基因转录水平。结果显示,经双酶切及PCR鉴定,目的基因的大小与预期相符。荧光显微镜和流式细胞仪均检测到细胞内绿色荧光蛋白的表达,荧光定量PCR检测到细胞内有NSP9基因的转录。本研究成功构建的猪繁殖与呼吸综合征病毒NSP9基因GFP融合表达质粒,为在细胞水平快速筛选有效的siRNAs提供了工具。     

Exploring the Effects of North–South and South–South Research Collaboration in Emerging Economies,the Colombian Case

International research collaboration (IRC) is associated with both positive and negative effects on the performance of research in emerging economies. While some authors claim that North–South collaborations improve scientific quality and visibility for Southern countries, others claim that it may entail the reorientation of research to comply with Northern agendas. South–South collaborations are thought to increase the focus on local affairs, therefore leading to a relatively small number of scientific international publications appearing in “high quality” journals. Research on the impact of IRC beyond publications in international journals has been neglected despite the importance of other products in knowledge creation. This research uses a broad range of scientific outputs to empirically assess such assumptions and explore the outcomes of IRC in Colombia. Results from multivariate regressions and nonparametric analyses show that, contrary to common assumptions, Colombian research teams collaborating with partners from the global South report higher scientific production, while those collaborating with Northern countries seem to contribute to local knowledge the most.     

State,Society and Markets in Argentina: The Political Economy of Neodesarrollismo under Néstor Kirchner, 2003–2007

The national Peronist social contract in Argentina has a long history rooted in syndicalism and populism. However, Menemismo in the 1990s, El Argentinazo in December 2001, and Kirchnerismo post crisis have all served to change the fundamental framework of the Argentine economy, the social underpinnings of that economy and how it intersects with global capital. This article is an attempt to identify the nature of Kirchner's administration through analysis of political economy, therefore seeking to facilitate a deeper understanding of the developmental nature and impact of the Kirchner administration of 2003–2007.     

Does Moderation Pay in a Consociational Democracy? The Marginalisation of the SDLP in the North of Ireland

A central question in the debate between “centripetalists” and “consociationalists” concerns whether power‐sharing arrangements provide incentives for moderation. This article helps to formulate an empirical answer through an examination of the electoral decline of the Social Democratic and Labour Party (SDLP) following the Good Friday Agreement (GFA) in the North of Ireland. Drawing on primary qualitative interviews with key players, this article argues that the SDLP were electoral losers under a system of ethnic out‐flanking. Sinn Féin has successfully presented itself as the “greener” and more robust representative of nationalist interests, whilst simultaneously moderating its message and operating the institutions of Northern Ireland. Sinn Féin has taken ownership of the GFA and has positioned itself as the party best able to ensure its delivery. Sinn Féin’s rights‐based agenda, and vibrant electoral machine, has resonated with the nationalist electorate who are less sure of what the contemporary SDLP stands for.     

Potency levels of regulated cannabis products in Michigan 2021–2022

Evaluation of cannabinoid concentrations in products from the legal cannabis market has been fraught with uncertainty. The lack of standardized testing methodology and the susceptibility of cannabinoids to degradation under certain storage conditions complicates the efforts to assess total tetrahydrocannabinol (THC) levels across wide geographic areas. There are few peer-reviewed surveys of cannabinoid concentrations in regulated products. Those that have been done have not characterized the effects of differences in analytical methodology, sample population, and storage conditions. Viridis Laboratories, which operates two cannabis safety compliance facilities in Michigan, has analyzed over 34,000 cannabis products throughout 2021 and 2022 before the sale in the regulated market. Fifteen cannabinoids in cannabis flower, concentrates, and infused products were tested using methanolic extraction and analysis by high-performance liquid chromatography with diode-array detection. Methods were validated before use, and the flower analysis procedure was certified by the Association of Analytical Collaboration. All the samples were tested before submission for sale and therefore had not undergone prolonged storage. The results are compared with those seen in other states as well as in the illicit market. Total THC levels in cannabis flower from the regulated market are significantly higher than those seen in illicit products. The distribution of cannabinoid levels is similar in flowers intended for either the medicinal or adult-use markets, with an average potency of 18%–23% of total THC. Total THC in concentrates averages up to 82%. Other cannabinoids are observed at significant levels, mostly in products specifically formulated to contain them. These results may act as a benchmark for potency levels in the regulated market.
