Social history, (Neo-)revisionism and mapping the 1930s Spanish left*

Revisionist historians and their Neo-Revisionist/conservative fellow travellers identify the Spanish left as the main cause of the civil war (1936–1939) that culminated in the establishment of the Franco dictatorship. Such claims are possible because these historians distort both the history of the left and the nature of social protest and mass mobilisation during these years. In part, the reliance of Neo-Revisionist/conservative historians on the methods of traditional political history – combined with their stubborn aversion to social history – makes it impossible for them to understand the left. This article argues that only through social history is it possible to comprehend the complex and shifting nature of protest dynamics in the 1930s. Indeed, many of the conflicts that played out in the political arena during these years were conditioned by structural economic problems and social tensions that resulted in diverse forms of radical contestation among the grassroots of leftist movements. Social, and indeed cultural history, are, therefore, central to any analysis of the myriad forms of these protest energies that flowed from the bottom up to shape the orientation of the leftist organisations.     

Divergent fates: company unions and employee involvement committees under the railway labor and national labor relations acts

Well known is that the National Labor Relations Act (NLRA, 1935) in the United States places a largely per se ban on nonunion employee representation (ER) groups which deal with employers over a term or condition of employment. Much less well known is that America’s other labor law, the Railway Labor Act (RLA, 1926), takes a different approach and permits employers to operate such councils and committees as long as they do not perform a collective bargaining function or interfere with workers’ free choice of a bargaining agent. Thus, under the RLA Delta Air Lines is able to operate what is today the closest living approximation to a 1920s-style ER plan while hundreds of other companies (e.g. Polaroid) under the jurisdiction of the NLRA have been forced over the years to disband similar groups on grounds they are a proscribed company union. No study to date has explored the history behind the RLA and NLRA’s divergent treatment of nonunion ER groups so this article takes a first look. The main part of the story covers the 1920–1935 period and examines the events, people, and experiences associated with company unions and ER in, respectively, the rail and manufacturing industries and why the legislative outcome in the former was a permissive stance on nonunion committees but prohibitive in the latter. The last part of the paper fast-forwards the RLA-NLRA story from the 1930s to contemporary law and practice in order to demonstrate how “history matters” when it comes to what employers can and cannot do with nonunion representation groups, such as works councils, participation and involvement committees, and dispute resolution forums.     

Sample Mining and Data Mining: Combined Real-Time and Retrospective Approaches for the Identification of Emerging Novel Psychoactive Substances

Novel psychoactive substances (NPS) are synthetic drugs that pose serious public health and safety concerns. A multitude of NPS have been identified in the United States, often implicated in forensic investigations. The most common and effective manner for identifying NPS is by use of mass spectrometry and the true utility lies within nontargeted acquisition techniques. During this study, a liquid chromatography quadrupole time-of-flight mass spectrometry (LC-QTOF-MS) assay was developed, validated, and implemented for forensic toxicology testing. A SCIEX TripleTOF™ 5600 + with SWATH^® acquisition was used. Resulting data were compared against an extensive library database containing more than 800 compounds. The LC-QTOF-MS assay was applied to the reanalysis of biological sample extracts to discover emergent NPS. More than 3,000 sample extracts were analyzed, and more than 20 emerging NPS were detected for the first time. Among these were isopropyl-U-47700, 3,4-methylenedioxy-U-47700, fluorofuranylfentanyl, N-methyl norfentanyl, 2F-deschloroketamine, 3,4-methylenedioxy-alpha-PHP, eutylone, and N-ethyl hexedrone.     

鸡白细胞介素-2受体基因γ链的转录分析与表达

以脾单个核细胞总RNA为模板,对鸡白细胞介素-2受体基因γ链(chIL-2Rγ)进行了RT-PCR,获得了一1 047 bp的开放阅读框,编码由348个氨基酸残基组成的分子质量为37.8 ku的蛋白多肽。预测的鸡IL-2Rγ多肽链中包含4个保守半胱氨酸残基、1个WSXWS基序和7个N连接的糖基化位点。鸡IL-2Rγ与其他动物IL-2Rγ在氨基酸水平上的同源性仅为21.4%~38.2%。RT-PCR检测发现,鸡IL-2RγmRNA分布于大脑、小脑、脊髓、腔上囊、脾、胸腺、骨髓、盲肠扁桃体、腺胃、肌胃、空肠、卵黄囊憩室、回肠、盲肠、直肠、心脏、肾、肺、肝、骨骼肌和皮肤,而在十二指肠和睾丸中没有检测到其转录。构建了鸡IL-2Rγ胞外区的原核重组表达载体,进行了表达和鉴定。     

美国法典1404(a)与非方便法院原则辨析

由于美国法典28卷1404（a）条款的立法规定在功能与措辞上均非常类似普通法上的非方便法院原则,因此很多学者误以为该立法规定与非方便法院原则之间并不存在实质性的差异。然而,这一看法并不正确。事实上,1404（a）条款立法在法律效果、证明标准以及具体适用方面均与非方便法院原则存在显著的区别。     

沿海十省(市)药品监管机构能力之比较研究

在构建社会主义和谐社会的当代中国,药品的安全性和有效性正日益引起人们的关注,而药品监管机构能力的建设与评估也开始成为社会监管领域的重要问题.通过回顾国内外已有的对政府能力概念和要素的研究,借用Nelissen的潜在能力和现实能力理论,结合世界银行2003年《世界发展报告》中对机构现实能力的要素分析和"行政储备"理论对机构潜在能力的要素分析,构建起药品监管机构能力的结构模型,并提出一套评估的指标体系.对数据进行标准化处理后,通过统计排序对沿海十省(市)药品监管机构能力进行评估和比较,进而利用最小二乘法(OLS)建立回归模型,分析潜在能力中的财力和人力因素对现实能力的贡献率.研究发现:地区财力对监管机构现实能力的影响较之人力因素要大,这在理论和实践中都可以得到证实;各地药品监管机构的潜在能力与现实能力之间存在较大差异,就那些现实机构能力较低的地区而言,现阶段有必要把工作重点放在医药企业生产经营行为的监管和农村地区医药监管基础设施的建设上;而对于潜在机构能力较低的地区来说,从"专业化、程序化和独立性"等方面提升机构整体的人力资源是当务之急.     

区域环境颗粒物污染特征研究

通过对北京经济技术开发区开展的大气环境和污染源监测,研究区域环境空气中颗粒物污染特征。根据不同功能区PM10(可吸入颗粒物)浓度空间分布特征和累积效应,表明区内道路扬尘和施工扬尘是该区域大气颗粒物的主要污染源。根据对道路边界的降尘监测,表明施工工地对道路扬尘的影响非常大。对于处于建设发展期的区域,加强施工扬尘和道路扬尘控制是保证空气质量的重要措施。     

甲基安非他命（冰毒）诱导基因表达变化研究进展

甲基安非他命进入机体后,其最根本的变化是引起了成瘾者许多基因转录和表达改变。这些基因包括与神经元损害有关的基因、与日节律有关的基因、与行为异常有关的基因及其它一些无法分类的基因。它们基因转录和表达水平增高或者降低引起了甲基安非他命成瘾者各种临床表现。研究这些基因表达可以为法医学鉴定提供依据。
