制度广义上包括个体的思想意识和政府的政策规定。缓解收入不平等,既应注重微观个体的意识重构,又应侧重政府层面的政策设计,因此,从主体行为的角度分析收入分配结构的调整和经济发展方式的转变是一种涉及制度基础的、追根溯源式的创新性尝试。文章的观点是:第一,缓解收入不平等应遵循一种“合理有效的平等机制”,即经济个体都可以而且应该充分利用其所拥有的和可获得的资源禀赋,去实现自由发展;第二,在不同收入阶层中,低收入者既应合理地看待不平等现象,又应通过积极努力以实现向上流动;高收入者则应有效地降低社会阶层间的心理割裂,同时又应主动地补偿低收入者的资源耗损;第三,政府应设计并遵循“合理有效的平等机制”,应搭建经济个体充分发挥资源禀赋的发展平台。  相似文献

社会中层出不穷的"闹大"是公共治理状况的一面"镜子",也是转型时期政策议程建构的重要路径。本文采用清晰集定性比较分析(csQCA),对2003-2019年发生的40个"闹大"案例进行比较研究。研究结果表明,上级(层)政府支持是"闹大"成功的必要条件。推动"闹大"成功的充分条件组合共有八种,可具体归纳为制度框架使用模式、集体施压模式、专家引导模式和暴力强推模式等四种解释模型。公民"闹大"成功是多个条件组合的结果,在核心条件发挥基础作用的前提下,适当的辅助条件更容易触发政策议程,推动问题解决。文章为公民"闹大"的行动逻辑提供了新的因果解释机制,也为理解形形色色的"闹大"现象提供了新的理论工具。  相似文献

作为十一月革命产物的魏玛制宪面临着两难困境,革命后的国际国内政治环境倒逼德国民主化,然而,无论“作为政治观念的民主”还是“作为统治形式的民主”,在德国都缺少历史与社会根基,魏玛制宪能依凭的民主传统与思想资源非常单薄。以民主主义政治理论家普罗伊斯为灵魂人物的制宪者代表德国人民作出一个根本政治决断,即为了德国免于苏维埃化就必须立即建立以议会民主制为根基的“人民国家”。为回应国内反议会民主制的强大政治意见,制宪者又引入全民公投与直选总统这两种准民粹主义民主制。魏玛宪法由此呈现出古典代议制民主与民粹主义民主并置的二元民主制模式。这个模式被认为是魏玛宪法的结构性缺陷和德国首个民主共和政体失败的宪制原因之一。德国宪制史上经历的民主制度与民主思想争锋,作为产生了世界性正反历史影响的典型事态,对当代思考宪法与议会制民主、民粹式民主、防御性民主的复杂关系,界定民主宪制的规范语义场依旧有镜鉴意义。  相似文献

Various studies have shown that women with psychopathy tend to commit crimes that are less violent than those of psychopathic men. The present study was designed to address the influence of psychopathy on the crimes committed by female offenders. A national sample of female offenders found NGRI or of diminished responsibility and at risk for criminal recidivism (OPG patients) was compared with a sample of female offenders who were convicted and imprisoned. Results of this comparison between the two groups of female offenders indicate that psychopathy is a transversal psychopathological dimension which may or may not be associated with other mental disorders. In both samples, the most commonly reported offenses among women with high PCL‐R scores were minor offenses, not particularly violent, but they appear to be related to typical psychopathic features such as superficial charm, pathological lying, and manipulation.  相似文献

This study describes the performance of handheld Raman devices for determining whether suspect pharmaceutical tablets declared to contain controlled substances were consistent with authentic (CWA) or not consistent with authentic (NCWA) tablets using a simple, rapid, field-friendly method capable of being used by nonexperts. Twenty-five authentic products and 84 known NCWA tablets were examined using three “parent” devices for a total of 327 analyses. On average, the parent devices yielded a true pass rate of 100%, a true fail rate of 98.4%, a false pass rate of 1.6%, and a false fail rate of 0%. The methods/libraries were then transferred to 13 identical “daughter” devices, which were used to examine 10 suspect finished dosage forms in duplicate (six known NCWA tablets and four authentic tablets) for a total of 260 measurements. On average, the daughter devices had a true pass rate of 100%, a true fail rate of 95.5%, a false pass rate of 4.5%, and a false fail rate of 0.0%. These data demonstrate that the parent–daughter electronic transfer method was successful, which permits the ability to develop methods in the laboratory that can be seamlessly pushed out to field devices. The methods can then be used to (i) prioritize samples for additional testing using other more time-consuming laboratory-based techniques needed to detect and quantify active ingredients and (ii) help support the interdiction of dangerous tablets at ports of entry, thereby preventing them from reaching the supply chain.  相似文献

Postmortem computed tomography (PMCT) is integrated into the evaluation of decedents in several American medical examiner offices and medicolegal death investigative centers in many other countries. We retrospectively investigated the value of PMCT in a series of firearm homicide cases from a statewide centralized medical examiner’s office that occurred during 2016. Autopsies were performed or supervised by board-certified forensic pathologists who reviewed the PMCT scans prior to autopsy. PMCT scans were re-evaluated by a forensic radiologist blinded to the autopsy findings and scored by body region (head–neck, thoracoabdominal, and extremities). Injury discrepancies were scored using a modified Goldman classification and analyzed with McNemar’s test. We included 60 males and 20 females (median age 31 years, range 3–73). Based on PMCT, 56 (79.1%) cases had injuries relevant to the cause of death in a single body region (24 head–neck region, 32 thoracoabdominal region). Out of these 56 cases, 9 had a missed major diagnosis by PMCT outside that region, including 6 extremity injuries visible during standard external examination. Yet all had evident lethal firearm injury. We showed that PMCT identifies major firearm injuries in homicide victims and excludes injuries related to the cause of death in other regions when a single body region is injured. Although PMCT has a known limited sensitivity for soft tissue and vascular pathology, it can be combined with external examination to potentially reduce or focus dissections in some of these cases depending on the circumstances and medicolegal needs.  相似文献

Fatal fall from a height initiated with a swinging motion on the sagittal plane of the victim's body is examined. Method of analytical mechanics is adopted to establish the functional relations between the swinging angle of the body and the force needed to sustain the body until release, and the amount of the horizontal displacement that would occur after release. The analysis is applied to support an expert opinion presented in a criminal court in which two accused were convicted of murder for dropping a female victim from a bridge. The results indicate that it is unlikely for the body to locate as recorded by the police investigation report in the case. This study demonstrates that a straightforward mechanical analysis can be utilized to examine uncommon falling scenarios.  相似文献

The literature on child sexual abuse (CSA) perpetrated by female sexual offenders (FSOs) is exiguous, and many studies have focused on judicial databases. The present retrospective study, instead, analyzed clinical and judicial data of a group of both victims and alleged FSOs, to additionally include women who have not been convicted by the criminal justice system, but who hold strong clinical suspicions of being perpetrators of CSA. The medical records and the Court files of 11 children and their eight suspected FSOs have been collected and critically reviewed in light of the literature to date. This approach allowed for a deeper understanding of the relationship between child and FSO. The authors hypothesize that the victims’ severe psychopathological outcomes were a result of a failure to develop appropriate attachments with their prospective caregivers, which could have been damaged by the pathological relationship with FSOs, who were the victims’ caregivers.  相似文献
