A novel method for cyanide quantification in human whole blood using ion chromatography with amperometric detection and its application to cyanide intoxication cases

Cyanide is a highly toxic agent that has been frequently used for suicide in South Korea. It is also used in various industrial fields, such as metal plating, in which many accidental cyanide intoxications have occurred. To overcome the disadvantages of conventional cyanide analysis methods, a simple and fast method for the analysis of cyanide in whole blood using ion chromatography (IC) with amperometric detection was developed in this study. Whole blood samples were deproteinized, diluted, and analyzed using an IC–amperometric detection system. The limits of detection and quantitation were 0.1 and 0.2 mg/L, respectively. The method showed good linearity in the range of 0.2 to 50 mg/L with R² > 0.99. The intra- and inter-assay precision and accuracy values were <10%. The established method was successfully applied to analyze whole blood samples from three cyanide intoxication cases.     

Analysis of off-farm work decisions among smallholder farm households in Burkina Faso

This article investigates off-farm work decisions by smallholder farm households. Using data on 1,101 households from Burkina Faso, it demonstrates that in addition to the usual household socio-demographic characteristics, remittances, access to information and beneficiary of specific training affect off-farm work decisions, as well as rainfall factors and idiosyncratic health shocks. Community characteristics such as accessibility and number of inhabitants are also key factors. While suggesting that off-farm work is less likely to be undertaken for accumulation purposes, these results have important policy implications. In particular, policy measures should consider each segment as a separate entity.     

跨境民族因素对阿巴边境地区毒品问题的影响

随着1979年苏联入侵阿富汗和阿富汗抗苏战争的开展,阿富汗和巴基斯坦边境地区的罂粟种植面积迅速扩大,毒品产量迅速增加,成为世界毒品市场的重要来源地。阿巴边境地区的普什图人和俾路支人等跨境民族在"金新月"地带的罂粟种植和毒品生产中扮演着重要的角色。20世纪80年代后,阿富汗生产的鸦片主要来源于阿巴边境的普什图人村庄,巴基斯坦的罂粟种植也主要集中在以普什图人为主的西北边境省和联邦直辖部落地区。多年以来,尽管阿富汗和巴基斯坦政府在阿巴边境地区不断采取禁毒措施,发展替代种植,但是均未能清除该地区的罂粟种植和毒品生产。阿巴边境的普什图人、俾路支人等民族长期种植罂粟并参与毒品走私的原因包括历史、政治和经济等因素。从历史上看,阿巴边境的普什图人有种植罂粟的传统,出售鸦片是他们重要的经济来源之一。从政治上看,阿富汗和巴基斯坦两国政府不能对边境地区进行有效的管理和控制,从而为边境地区的普什图人和俾路支人种植罂粟和从事毒品走私提供了条件。此外,一些政党为了拉选票而支持当地人们种植罂粟也是重要的政治原因。从经济上看,种植罂粟的收入要高于种植小麦的收入,贩卖毒品的利润较高是吸引阿巴边境的普什图人、俾路支人等民族种植罂粟和从事毒品走私的重要原因。     

Red Tape,Rule Burden,and Legitimate Performance Trade-Offs: Results from a Vignette Experiment

Abstract

Goals in the public sector are complex and managers can face situations in which pursuing one legitimate goal necessitates performance trade-offs in other areas. This study tests how knowledge of legitimate performance trade-offs shapes the perception of red tape. Using a vignette experimental design and a sample of university students, between group t-tests and regression analyses suggest that, when evaluating increased rule burden, individuals that are provided with information about how objectively burdensome rules serve alternative values such as equity and effectiveness associate them with lower levels of red tape. A series of Monte Carlo simulations suggest that this effect is substantial.     

论科学发展观视野中的地方政府绩效评价体系的优化

科学发展观的提出受到各界的普遍关注并得到了高度的评价。为确保科学发展观的贯彻落实,地方政府绩效评价体系的优化显得尤其重要。首先,要按照科学发展观的要求,构建科学的评价指标体系;其次,要完善评价主体结构;再次,要开发利用科学的评价技术与方法;最后,必须制定完善的法律法规,规范地方政府绩效评价活动。     

A Dialectic Study of the Structure and Basic Concepts of Traditional Chinese Law and an Analysis of the Relationship Between li (ceremony) and fa (law)

In the course of history, the meaning of fa (a Chinese character with an approximate meaning of “law”) has not been invariable, and its connotation in modern times has been enriched constantly, so as to incorporate many elements of ancient li (ceremony). If the modern concept of law, already changed and still changing, is to be used to mechanically compare and interpret traditional Chinese law, misunderstandings might arise. Actually, li and fa are indispensable components of traditional Chinese law, and the lack of necessary study of the li will prevent us from understanding and explaining the spirit of traditional Chinese law. In traditional Chinese law, “fa” usually refers to an institutional dimension, especially after Qin and Han dynasties, whereas li, especially li yi (moral basis for rites and ceremonies), is where the value and spirit of traditional Chinese law can be found.

中国汉族与日本群体DYFl55S1基因座的遗传多态性

目的探讨Y染色体DYF155S1基因座的遗传多态性及群体间差异。方法 应用MVR-PCR、荧光显谱及DNA序列分析技术,对来自中国群体(北方汉族,64例)和日本群体(43例)男性个体的DYF155S1基因座进行初步分析。结果107例样本共检出了5种重复序列类型,包括新的命名为6型的重复序列,它是在1型的基础上T22A置换所形成,仅存在于日本群体,可作为民族特征性遗传标记。2群体重复序列的排列方式以3134顺序为主,在中国和日本群体中各占73.44％和67.44％,是黄种人的特点。134顺序在中国群体中占第二位,为17.19％,6134排列占日本群体的16.28％。3’端的4型重复序列的平均数目在日本群体为8.8条,明显低于中国群体的12.5条。结论DYF155S1基因座具有非常高的遗传多态性和明显的群体差异。     

大鼠液压冲击脑损伤TGF-β1及其受体TβR I的表达

目的观察脑损伤后TGF-β1及其受体TβRI蛋白表达及其时序性变化,探讨脑损伤的分子机制及法医学脑损伤时间推断。方法用免疫组织化学方法观察大鼠液压冲击脑损伤后TGF-β1及其受体TβRI蛋白在伤后不同时间(30 min、1 h、3 h、6 h、12 h、1 d、3 d、7 d)的表达情况,以正常大鼠及手术大鼠作为对照。结果 (1)正常及手术对照组大鼠脑组织内有低水平的TGF-β1及TβRI表达;(2)脑损伤后1～3d,大脑皮质和脑干TGF-β1/TβRI蛋白表达逐渐增加,7 d时仍维持在高表达水平;(3)海马冲击后12 h～1 d逐渐增加,3 d时仍处于高表达水平,7 d时已开始下降。结论脑损伤可诱导TGF-β1/TβRI基因在脑内表达,其时序性改变可望用于法医学脑损伤时间推断。     

Data Protection: An Opening Door?

Swedish public law has incorporated a general rule of public access to documents, and to information in the wider sense, since the Freedom of the Press Act of 1766. On the Community level, the relationship between Regulation (EC) 45/2001 on data protection and Regulation (EC) 1049/2001 on public access to documents exemplifies the tension between the public's interest in scrutinising the administration carried on in its name, and the integrity of the individual. However, a similar tension exists between Sweden's Personal Data Act of 1998, implementing Directive 95/46, and the Freedom of the Press Act. A misuse model of data protection law, by seeking to concentrate on serious rather than technical infringements of privacy, might serve to ease the tension.
