The challenge faced by governments in the regulation of powerful private actors has allegedly intensified in recent years. This study explores the means at the disposal of governments, and their effectiveness, with respect to the regulation of private actors that demonstrate considerable independence and political efficacy. It is argued that a modified ‘Contextual Interaction Theory’ (CIT), which focuses on the interaction between generic policy instruments (carrots, sticks, and sermons) and target group attributes (motivation, information, and power), and is augmented by a consideration of a separate institutional dimension, offers a useful analytical framework for understanding both the challenge faced by governments and the options for dealing with it. This framework is applied to a study of the introduction of ‘new accountability’ to Australian and Israeli non‐government schools. The use of the standard CIT lenses helps explain Australian success and Israeli government failure in the introduction of new accountability. Australian success is attributable to a judicious mix of ‘hard’ and ‘soft’ instruments that favorably impacted target group information and motivation. In Israel, in contrast, policy instrument mixes failed to alter the main target group's oppositional stance. Institutional engineering, however, could provide a promising way for Israeli policymakers to enhance policy instrument effectiveness, by influencing target group power and motivation.  相似文献

This commentary provides an overview of the four papers in this issue of Review of Policy Research on the politics of climate change. The papers all address in one way or another aspects of how federal‐type systems are dealing with the collective action and multilevel governance issues of climate change policy. The comparative study of federal systems provides insight into how domestic authority is so often overlapping and divided when dealing with greenhouse gas emissions and climate change. Federal arrangements offer a rich array of norms, institutions, and practices for tackling these problems. Federal systems grapple continuously with the kinds of issues that are the most intractable in the climate change case, such as overcoming interregional differences of interests and values. A common federal feature is competition among subnational governments and between them and national or federated governments over climate change policy, which has been especially significant in the United States and in Canada in the relative absence of national action––although soberingly, the whole is as yet nowhere near as great as the sum of the parts. More significant, but rarer is the achievement of tighter coordination in federal systems achieved through intergovernmental co‐decision, as seen in the European Community and Australia. This has been accomplished in large part due to a consensus among all intergovernmental parties on the nature of the problem and congruence with the existing international regime, characteristics missing in the North American context.  相似文献

Forensic science laboratories are being challenged by the expanding decentralization of forensic capabilities, particularly for digital traces. This study recommends laboratories undertake digital transformations to capitalize on the decentralization movement, develop a more comprehensive understanding of crime and security‐relevant problems, and play a more central role in problem‐solving collaboratively with law enforcement organizations and other stakeholders. A framework for the bilateral transfer of information and knowledge is proposed to magnify the impact of forensic science laboratories on abating crime, strengthening security, and reinforcing the criminal justice system. To accomplish digital transformations, laboratories require personnel with different expertise, including investigative reasoning, knowledge codification, data analytics, and forensic intelligence. Ultimately, this study encourages managers, educators, researchers, and policymakers to look beyond the usefulness of forensic results for solving individual investigations, and to realize the value of combined forensic knowledge and intelligence for developing broader strategies to deal with crime in digitalized society.  相似文献

In this article, we explore variations in procedural justice delivered in face‐to‐face encounters with citizens before and after the implementation of body‐worn cameras (BWCs). We draw on recent advances in the measurement of procedural justice using systematic social observation of police in field settings in the Los Angeles Police Department. Data collected on 555 police–citizen encounters are examined in bivariate and multivariate models exploring the primary hypothesis that BWCs affect procedural justice delivered by police directly and indirectly. Our results indicate that significant increases in procedural justice during police–citizen encounters were directly attributable to the effect of BWCs on police behavior as well as to the indirect effects on citizen disrespect and other variables. The implications for policy include explicit measurement and monitoring of procedural justice or elements such as officer discourtesy in departments adopting BWCs. Further research questions such as more detailed examination of citizens’ behavior changes under BWCs are also considered in the context of the findings.  相似文献

A new pairwise osteometric pair‐matching approach based on the Z‐transform method is presented. In contrast to previous methods that perform a global t‐test on the summed skeletal element pair measurement distances, this approach performs t‐tests on each individual distance, facilitating the capture of measurement‐specific variation. This new approach is compared to published pairwise sorting methods using a standard reference dataset of postcranial remains maintained by the Defense POW/MIA Accounting Agency. Receiver operating characteristic curve analysis indicates significantly improved performance for the clavicle and radius over all previous methods (p < 0.01). The z‐transform method weighted by the effect size outperformed the t‐test (Byrd and Adams) and the mean t‐test (Lynch) for all elements (p < 0.01). The method performed better than the absolute value t‐test (Lynch) for five elements (p < 0.01) and performed at least as well for the remainder. To facilitate usability all methods are available at: https://github.com/spawaskar-cora/z-transform-method .  相似文献

The same‐source problem remains a major challenge in forensic toolmark and firearm examination. Here, we investigate the applicability of the Chumbley method (J Forensic Sci, 2018, 63, 849; J Forensic Sci, 2010, 55, 953) (10,12), developed for screwdriver markings, for same‐source identification of striations on bullet LEAs. The Hamby datasets 44 and 252 measured by NIST and CSAFE (high‐resolution scans) are used here. We provide methods to identify parameters that minimize error rates for matching of LEAs, and a remedial algorithm to alleviate the problem of failed tests, while increasing the power of the test and reducing error rates. For 85,491 land‐to‐land comparisons (84,235 known nonmatches and 1256 known matches), the adapted test does not provide a result in 176 situations (originally more than 500). The Type I and Type II error rates are 7.2% (6105 out of 84,235) and 21.4% (271 out of 1256), respectively. This puts the proposed method on similar footing as other single‐feature matching approaches in the literature.  相似文献

Primary intraventricular hemorrhage (PIVH) is a rare type of stroke defined as bleeding within the ventricles of the brain without any associated parenchymal hemorrhage. Here, we reported two cases of sudden death due to PIVH. One of the patients was found dead under a highway bridge without witnesses, and the other patient was hospitalized with hemorrhage in the ventricular system, as revealed by a head computed tomography scan. In these two patients, autopsy and macroscopic examination only showed hemorrhages in the ventricular system without any traumatic brain injury or other intraparenchymal hemorrhage. The sources of bleeding for both patients were ultimately confirmed as ruptured brain arteriovenous malformations located in the subventricular zone. We reported these cases to broaden our understanding of sudden death associated with PIVH, especially when caused by brain arteriovenous malformation. We also summarized the essential details of the diagnoses and available technical methods for PIVH cases.  相似文献

This paper provides a retrospective of the DNA analysis performed by the Armed Forces Medical Examiner–Armed Forces DNA Identification Laboratory between 1990 and 2018. Over 13,000 postcranial osseous materials, comprised of wartime losses from World War II, the Korean War, and South‐East Asia, were examined by the following: mitochondrial DNA sequencing, a modified AmpFlSTR® Yfiler?, AmpFlSTR® MiniFiler?, PowerPlex® Fusion, or NGS. Four different DNA extraction protocols were used: incomplete demineralization coupled with an organic purification; complete demineralization with an organic purification; complete demineralization with an inorganic purification using QIAquick PCR Purification Kit; and a protocol designed specifically for use with next‐generation sequencing. In general, complete demineralization coupled with an organic purification was the optimal extraction protocol for sequencing of mitochondrial DNA, regardless of the osseous element tested. For STR testing, demineralization paired with an inorganic purification provided optimum results, regardless of kit used or osseous element tested.  相似文献

Forensic pathologist use soot and/or stippling surrounding entrance gunshot wounds in categorizing range of fire. If absent, some pathologists suggest utilizing histology when the range is diagnostically critical. This study investigates the concordance of macroscopic and microscopic findings in estimating range of fire by evaluating gunshot entrance and exit wounds made through human tissue analogs at defined distances using two handgun calibers. Examination of over 150 entrance wounds verified the ease of visually detecting soot from a muzzle distance of contact to 1 foot (30.5 cm), and its absence at 9 feet (274.3 cm). Distinctly apparent was bullet wipe surrounding the entrance wounds regardless of muzzle distance. Although variations existed, dark material was histologically identified in many skin, soft tissue, and bone sections at all ranges with both calibers. These nonparallel results decrease the dependability of histology for range of fire estimation and reinforce using gross observation.  相似文献

Artemisia absinthium (wormwood), a common ingredient in absinthe, contains the compound thujone, which is unregulated by the U.S. Drug Enforcement Agency. Thujone can cause an “unregulated legal high” in higher concentrations. The European Union limits thujone from Artemisia species to 35 mg/kg while the U.S. Food and Drug Administration requires less than 10 ppm to be “thujone‐free.” However, individuals can smoke or ingest A. absinthium in different forms. This study developed a polymerase chain reaction (PCR) high‐resolution melt (HRM) assay to detect and identify A. absinthium based on primer specificity, sensitivity, repeatability, and robustness. A triplex assay was performed with three “unregulated legal high” species: Datura stramonium, Merremia tuberosa, and A. absinthium; the PCR HRM assay detected and identified each plant at melt temperatures 77.42 ± 0.20°C, 83.88 ± 0.22°C, and 87.77 ± 0.15°C, respectively. The primer set developed distinguished A. absinthium from a variety of plant species and was successfully triplexed.  相似文献
