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.     

十八大以来我国“放管服”改革的动因、成效、困境及推进策略

党的十八大以来,“放管服”改革已经持续多年,改革力度之大、改革范围之广、改革程度之深,是历次改革中所没有的。这场改革动因主要是推进国家治理体系与治理能力的现代化、应对国际复杂形势及新智能革命带来的挑战、满足人民对美好生活的向往。改革的举措主要有行政审批制度改革、清单制度改革、服务流程再造、证照分离、减税减负、优化服务、监管改革等。通过改革促进营商环境便利化、服务方式智能化、市场监管精准化,有效激发了市场活力,规范了政府权力,化解了市场主体的“堵点”“难点”“痛点”。改革也在制度、监督以及基层积极性等方面存在问题。未来“放管服”改革进一步推进的策略主要包括价值的调适整合、结构的互动整合、机制的协同整合、技术的嵌入整合、执行的配套整合、制度的优化整合等。     

豆状囊尾蚴外泌体的分离鉴定及其对家兔免疫应答的调节作用

为探究豆状囊尾蚴外泌体对家兔免疫应答的调节作用,以收集的豆状囊尾蚴分泌排泄产物(ESP)为材料,通过差速离心法分离外泌体,经透射电镜和Western-blot分别对其形态和标志分子进行鉴定。分别用外泌体和ESP免疫家兔,ELISA方法检测家兔血清中特异性抗体和血清细胞因子水平,并通过人工攻虫感染评价其免疫保护效果。结果显示,豆状囊尾蚴外泌体直径为30~150 nm,呈圆形或椭圆形,有完整的脂质双分子层膜结构,且含有外泌体标志蛋白CD63。而且,外泌体免疫组血清特异性抗体、IL-10和IL-4的水平显著升高(P<0.05),而IFN-γ和TNF-α显著降低(P<0.05)或差异不显著。经剖检发现,豆状囊尾蚴ESP免疫组和外泌体免疫组的减虫率分别为65.17%和24.88%。结果表明,外泌体通过上调宿主抑炎因子的表达,诱导宿主产生了Th2型细胞免疫应答,从而有利于囊尾蚴在宿主体内的存活。     

走出“共犯与身份”的教义学迷思:“主从犯体系”下身份要素的再定位

我国"主从犯体系"不同于德日区分制体系,主要表现为作用分类法与分工分类法具有实质差异、主犯判断与正犯评价存在根本区别。在欠缺身份犯总则性规定的前提下,不宜直接运用德日区分制体系下的"共犯与身份"理论来解决相关问题,而应当对其进行中国语境的转化。据此,"违法的连带性"应转换为"违法的共同性","责任的个别化"应蜕变为对"不法程度"及责任要素的双重评价。故而,在"主从犯体系"下,身份的作用仅限于两点:一是在整体上或共同违法意义上作为犯罪构成要件,从而在非身份者与身份者实施的共同犯罪中,身份者未必都是主犯,也可以是从犯或胁从犯;二是在归责意义上,非身份者的责任在同等条件下相对于身份者会有所克减。

Sex offender punishment and the persistence of penal harm in the U.S

The U.S. has dramatically revised its approach to punishment in the last several decades. In particular, people convicted of sex crimes have experienced a remarkable expansion in social control through a wide-range of post-conviction interventions. While this expansion may be largely explained by general punishment trends, there appear to be unique factors that have prevented other penal reforms from similarly modulating sex offender punishment. In part, this continuation of a “penal harm” approach to sex offenders relates to the past under-valuing of sexual victimization. In the “bad old days,” the law and its agents sent mixed messages about sexual violence and sexual offending. Some sexual offending was mere nuisance, some was treatable, and a fraction “deserved” punishment equivalent to other serious criminal offending. In contrast, today's sex offender punishment schemes rarely distinguish formally among gradations of harm or dangerousness. After examining incarceration trends, this article explores the historical context of the current broad brush approach and reviews the unintended consequences. Altogether, this article reinforces the need to return to differentiation among sex offenders, but differentiation based on science and on the experience-based, guided discretion of experts in law enforcement, corrections, and treatment.     

论通过首长负责制实现环境善治

我国在"十一五"规划中将节能减排作为约束性的指标,取得了良好的环境治理效果.这一做法的成功之处是实行了节能减排责任制,实行行政问责制.这些做法体现了责任政府的要求,抓住了环境治理问题的核心,发挥了行政首长负责制的优势,提高了各级政府的行政执行力.在今后的环境治理中,我们需要对这一制度加以完善,如扩展环境指标的范围、完善环境问责的对象和追究程序等.

论警察人权的保障

警察作为一个特殊的社会群体,其人权状况不容乐观。警察执行公务过程中的人权受损现象未有改观,警察人权潜在的受损状况日益突出。构建和谐社会必须高度重视警察人权保障工作。保障警察人权的核心是树立＂以警为本＂的全新理念,以此为指导创新警察人权保障机制,建立专门的警察人权监督保障组织,建立健全法律法规和相关制度,加强舆论宣传,提高警察的自我维权意识。
