县域社会违建执法的组织形态与治理绩效辨析

县域社会违建执法需要一定的组织载体,但在不同农村类型中,体制层面执法资源配置不均和社会层面违建个体情境差异共同塑造了不同类型的政府执法组织,并产生不同治理绩效。在城中村,正式化执法组织具备常规执法权且执法密度大,虽能够强化执法效果,但在执法过程中始终存在政府与征拆居民的利益博弈;在城郊村,正式化与半正式化相结合的执法组织有助于强化政府执法力量和权威,但受信息制约和人情关系影响容易产生灰色利益空间,进而侵蚀执法目标;在远郊村,半正式化执法组织本身没有专业执法权,政府常在一定时期内通过组织动员手段来补强执法力量,但执法绩效具有不稳定性。三类农村违建执法组织的治理绩效差异,反映出国家法律在县域城乡社会落地的非均质性。     

The Mediating Role of Ethical Climate in the Relationship Between Performance Appraisal and Organizational Performance

Although prior research has consistently established a positive relationship between performance appraisal and organizational performance across different research contexts, the mechanisms that underlie this link remain unclear. The present study attempts to fill this void by testing the mediating role of ethical climate in the relationship between performance appraisal and organizational performance across 181 Nigerian public sector agencies. Cross-sectional mediation analyses were performed using partial least squares path modeling approach. Results indicated that performance appraisal was positively and significantly related to organizational performance. Regarding the mediating effect, ethical climate significantly mediated the relationship between performance appraisal and organizational performance. The study made recommendations and drew suggestions for future research to enhance the performance of public sector agencies.     

“Those who know don’t tell”: David Hammons c. 1981†

Drawing on original archival research, as well as discourses in post-WWII art history, performance studies, and black studies, this article maps the use of rumor closely associated with David Hammons, with regard to two performative actions enacted in downtown Manhattan in 1981, now known as Pissed Off and Shoe Tree. These two performances occurred on and around the public sculpture T.W.U. (1980–81) by Richard Serra. Taking up how these works consider the specificity of social life pertaining to historically marginalized bodies and neighborhoods, this article argues that Hammons’s work in this period employs obscurity as a resistance to knowledge as it is codified and legitimized in institutional discourses within and beyond art institutions.     

A case of fatal intoxication from metformin

A case of fatal intoxication from metformin is presented. The decedent was an obese 58-year-old-woman with type II diabetes, in whom severe lactic acidosis secondary to metformin accumulation was precipitated by acute renal failure. She had been on metformin 500 mg twice a day. Postmortem blood was deproteinated with acetonitrile, washed with dichloromethane, and the resulting supernatant injected into high-performance liquid chromatography system. Separation was performed on a analytical 125 x 4 mm i.d. RP-8 column. The wavelength was set at 235 nm. The mobile phase was acetonitrile (40%), sodium lauryl sulfate, and sodium dihydrogen phosphate adjusted to pH 5.1 (60%) at a flow rate of 1.0 mL/min. The concentration of metformin in postmortem blood was 77.3 microg/mL. The qualitative result was also confirmed by LC/APCI/MS/MS analysis.     

我国行刑联动信息共享平台运行绩效量化评价——基于对上海市食品药品行政执法的实证研究

为了实现行政执法与刑事司法的有效衔接,2005年上海市率先建立“行政执法与刑事司法衔接的信息共享平台”,随后,信息共享平台建设工作在全国范围内广泛推行,并且应用于各个行政执法领域。目前,我国信息共享平台总体运行情况良好,对提高行政执法效率,打击犯罪行为起到了正向促进作用,但也存在信息共享平台分布不均衡、使用率低和监督不力等问题,需从扩大推行范围、改进平台功能、加强监督管理等方面加以完善。     

Detection of amitriptyline, citalopram, and metabolites in porcine bones following extended outdoor decomposition

Skeletal remains of a domestic pig were assessed for relative distribution of amitriptyline, citalopram, and metabolites. Following acute exposure and outdoor decomposition for 2 years, drugs and metabolites were analyzed in 13 different bones. Bones were pulverized following a simple wash procedure, and drugs were extracted by passive incubation in methanol, followed by solid-phase extraction. Samples were analyzed by ultra-high performance liquid chromatography (UHPLC) and confirmed with gas chromatography-mass spectrometry. The Kruskall-Wallis test showed that bone type was a main effect with respect to drug level for all analytes, with levels varying from 33- to 166-fold. Ratios of levels of drug to that of the corresponding metabolite were less variable, varying roughly one- to eightfold. This suggests limitations in the interpretive value of drug measurements in bone and that relative levels of drug and metabolites should be further investigated in terms of forensic value.     

科技劳动价值创造与计量

由于科技劳动可以创造出巨量价值,因而有人提出用知识价值论取代劳动价值论。这是对科学技术劳动的特点不甚了解的表现。科学研究和技术操作是两种不同的劳动方式,这两种劳动方式是由于人有继承前人抽象思维的结果并有把抽象还原为现实具体的两个特性产生的。这两种劳动方式创造的价值和剩余价值可以分别计量。     

Biometric Security and Privacy Using Smart Identity Management and Interoperability: Validation and Vulnerabilities of Various Techniques

The central position of this article is that validation and interoperability are paramount for the effective and ethical use of biometrics. Illuminating the relevance for policymakers of the science underlying the security and privacy aspects of biometrics, this article calls for adequate and enforceable performance metrics that can be independently corroborated. Accordingly, the article considers biometrics and forensics for the dual challenges of addressing security and privacy using smart identity management. The discussion revolves around the concepts of “personally identifiable information” (PII) and interoperability with emphasis on quantitative performance analysis and validation for uncontrolled operational settings, variable demographics, and distributed and federated operations. Validation metrics includes expected rates of identification/misidentification, precision, and recall. The complementary concepts of identity and anonymity are addressed in terms of expected performance, functionality, law and ethics, forensics, and statistical learning. Biometrics encompasses appearance, behavior, and cognitive state or intent. Modes of deployment and performance evaluation for biometrics are detailed, with operational and adversarial challenges for both security and privacy described in terms of trustworthiness, vulnerabilities, functional creep, and feasibility of safeguards. The article underscores how lack of interoperability is mostly due to overfitting and tuning to well‐controlled settings, so that validation merely confirms “teaching to the test” rather than preparation for real‐world deployment. Most important for validation is reproducibility of results including full information on the experimental design used, that forensic exclusion is allowed, and that scientific methods for performance evaluation are followed. The article concludes with expected developments regarding technology use and advancements that bear on security and privacy, including data streams and video, de‐anonymization and reidentification, social media analytics and cyber security, and smart camera networks and surveillance.     

Measuring State Environmental Policy

Studies of environmental policy employ various empirical strategies for measuring state environmental effort. The majority of these strategies can be divided into four categories: indices of state programmatic indicators, government expenditures, pollution abatement costs, and regulatory enforcement actions. In this article, we argue that these measures are empirically distinct, capture different attributes of state environmental policy, and are correlated with different intrastate factors. Thus, the choice among environmental policy measures is substantively important for researchers to consider, and we conclude by providing advice to scholars concerning choosing among these measures.
