One important but often understudied area of research in public administration is the effect of e‐government on administrative discretion. This article examines e‐government factors that influence administrative discretion through a survey of local governments. The focus of this study is on Egyptian local governments, which are using e‐government to modernise public service delivery. Through a survey of administrative officials in these governments, this study found evidence that e‐government factors of collaboration and organisational change influenced administrative discretion. Other common factors noted in the literature such as size of the local government and demand by citizens for e‐government did not register an effect on administrative discretion. The results of this study imply that local governments should do more to enhance e‐government to reduce administrative discretion, especially in the area of increasing collaboration.

Dimitrov et al. argue that nonregimes are a worthy object of research attention that can contribute to international regime theory. Case studies, however, are still sparse. In this article, I examine Arctic haze, an issue area where a transnational environmental problem existed but no regime formed. Arctic haze was (re‐)discovered in 1971 but by 2000, the window of opportunity to form a regime had closed. What factors explain why an Arctic haze regime was not formed between 1971 and 2000? I claim science‐based factors play the dominant role. An analytical approach applicable to the science‐policy interface was employed. Using this approach, I conclude that the Arctic haze nonregime is best explained by the absence of scientifically documented and compelling transboundary consequences to ecosystems and humans. This is a product of the unique nature of the Arctic atmosphere. 相似文献

The objective of the paper is to examine how firms have dealt with the trade‐off between flexibility and uncertainty that is characteristic for the decision‐making of firms in coping with self‐regulatory initiatives in general and the comply‐or‐explain principle in corporate governance in particular. Using unique data for 126 listed Dutch firms, we find that firms respond to this self‐regulatory initiative by largely complying with the code recommendation, possibly out of fear that the firm's reputation may be damaged. Furthermore, we find evidence suggesting that firms confine themselves to adopting a specific set of code recommendations and use similar arguments to explain non‐compliance. Our findings indicate uniformity in adopting the standard of good governance which is not in line with the logic of corporate governance codes and casts doubt on the effectiveness of this form of soft law. Overall, the paper's findings indicate that more restrictive (regulatory) instruments may be necessary to make firms conform to the spirit of codes. 相似文献

The accurate quantification of target DNA is an important step in the short tandem repeat analysis of forensic biological samples. By utilizing quantification data to control the amount of template DNA in the polymerase chain reaction (PCR), forensic scientists can optimize testing and minimize the consumption of limited samples. The ability to identify and quantify target DNA in mixed-species samples is crucial when it may be overwhelmed by nontarget DNA, as in cases of dog attack. We evaluated two quantitative real-time PCR assays for dynamic range, species specificity, and inhibition by humic acid. While both assays proved to be highly sensitive and discriminating, the Melanocortin-1 Receptor (MC1R) gene Taqman assay had the advantages of a shorter run time, greater efficiency, and safer reagents. In its application to forensic casework, the MC1R assay has been advantageous for quantifying dog DNA in a variety of mixed-species samples and facilitating the successful profiling of individual dogs. 相似文献

The "humane killer" or captive-bolt gun, is the tool/weapon widely used in meat industry and private farmer households for slaughtering animal stock. Out of 17,250 autopsies performed at the Institute of Forensic Medicine in Novi Sad during the 15-year period (1991-2005), 29 cases of suicides and two homicides were committed by captive-bolt pistols. Wounds inflicted by captive-bolt guns have specific morphological features, distinctive from wounds made by other kinds of hand firearms. Selected features of the captive-bolt wounds (punched round entrance and a double pattern of smoke soiling) depend on distance and angle of instrument at the time of firing. Autopsy findings were compared with an experimental model consisting of 20 domestic pigs. Obtained results confirmed that the appearance of the entrance hole and soot deposits, along with differences in shape, location, extent, and density of soot blackening, could be useful in identification of weapon, direction of discharge, shooting distance, and angle of the muzzle to the frontal and sagittal planes of the head at the moment of fire. 相似文献

Abstract: Human scent evidence is utilized as an investigative tool through canine scent discriminations based on the premise that human scent is an individualizing characteristic. This study describes the development of what is effectively a human scent barcode consisting of the relative ratios of an individual's "primary odor" compounds utilized to determine a reproducible and individualizing profile which can be stored in a searchable database for a proof of concept of human scent as a biometric measure. Triplicate hand odor samples were evaluated from 10 subjects utilizing solid phase micro-extraction gas chromatography/mass spectrometry (SPME-GC/MS) and compared via Spearman Rank Correlations. Narrowing the compounds considered for each subject to only those common in all three samples, or a subject's "primary odor constituents," produced a greater degree of both individualization and discrimination; at both correlation thresholds of 0.9 and 0.8, the individuals were correctly discriminated and identified in 99.54% of the cases. 相似文献

Abstract: This article extends the application of 1,2,4‐triazine‐based chromogenic reagents to the detection of nonferrous metal traces left on contact with canvas and human skin. The possibility of detection of iron traces resulting from contact with objects made of stainless steel was investigated as well. Additionally, the ability of triazines to form chromatic complexes with Zn2+, Ni2+, Co2+, Cu2+, Cr3+, and Al3+ ions was studied spectrophotometrically. Molar absorption coefficients, ranging from 8.8 to 29.9 × 103/M/cm, provide high sensitivity of 1,2,4‐triazines toward nonferrous ions, thus, enabling the detection at concentrations as low as a few μM. The method was sensitive enough to detect traces resulting from a 1‐min contact with a stainless steel made object, which is commonly considered as a corrosion‐resistant material. The amounts of metal ions transferred to the skin after a 2‐min contact with objects made of brass, zinc, and copper were sufficient to develop chromatic imprints. 相似文献

Abstract: Machinery‐related fatalities are one of the leading causes of traumatic occupational deaths. In our report, we present the case of a 40‐year‐old male who suffered a severe head trauma while working in a cut‐foam industry and died despite an early craniectomy. The radiological reconstruction of the skull based on preoperative computed tomography scans disclosed a large depressed conical fracture of the left parietal bone. The 3D‐reconstruction of the work area, combined with a fit‐matching analysis between the machinery and the depressed skull fracture allowed us to conclude that the head was crushed between the sliding bar of the cutting device and the metallic protuberance on the opposite side. The case underlines the importance of a detailed workplace investigation and of a thorough evaluation of all circumstantial, clinical, radiological, and autopsy data in the reconstruction of machinery‐related fatalities to identify any possible legal responsibilities of the worker and/or the employer. 相似文献

Abstract: We investigated toxicological and pharmacogenetic factors that could influence methadone toxicity using postmortem samples. R‐ and S‐methadone were measured in femoral blood from 90 postmortem cases, mainly drug users. The R‐enantiomer concentrations significantly exceeded that of the S‐enantiomers (Wilcoxon’s test, p < 0.001). The samples were divided into four groups according to other drugs detected (methadone only, methadone and strong analgesics, methadone and benzodiazepines, or methadone and other drugs). There was no significant difference in any of the R‐methadone/total methadone ratios among the four groups. The median R/S ratio was 1.38, which tends to be higher than that reported for the plasma of living subjects. In addition, we investigated whether small nucleotide polymorphisms in the MDR1 gene that encode the drug transporter P‐glycoprotein were associated with the concentrations of R‐ and S‐methadone and its metabolite 2‐ethylidene‐1,5‐dimethyl‐3,3‐diphenylpyrrolidine. No significant association was detected. 相似文献
