The aim of the current study is to explore the relationship between emotional intelligence and job performance in a sample of 310 police officers. The results show significant correlations between EI levels and police job performance. After controlling for general mental abilities and personality traits, EI has been found to explain additional incremental variance in predicting police job performance. Applied implications of the findings for police organizations are discussed.  相似文献

Abstract: The dental identification of edentulous individuals can be challenging based on the lack of antemortem materials and unique features visible on radiographs. The constant resorption of the alveolar ridges further complicates the process. The purpose of this study was to quantify the error rate and reliability of dental identifications based on a comparison of synthesized antemortem and postmortem radiographs of edentulous individuals. Ten observers examined ten cases on two occasions and reported dichotomous and conclusion level decisions. These were analyzed using Kappa and Receiver Operator Characteristics. The mean area under the curve was 0.75 and the mean sensitivity was 0.57 and specificity was 0.83. These results suggest that dental identifications of edentulous individuals using radiographs alone have a high error rate and should be dual reported. These data add further weight to the argument that all dental prostheses should be labeled.  相似文献

Abstract: This paper summarizes the results of a survey of ipac members carried out in the winter of 1987–88. Members' views were sought about the education and training of good senior public servants, administrative change and reform and the sources of innovation in public administration. In spite of great diversity in background and present condition, the members showed a high degree of unity in regarding public administration as a practical activity very much under the control of administrators. It is a world of nuances, where change does occur, but never quite as planned and seldom according to theory. Sommaire: Cet article résume les résultats d'une enquête menée auprès des membres de I'IAPC pendant I'hiver de 1987–1988. On a demandé les opinions des membres sur la formation et le développement des cadres supérieurs du secteur public, sur le changement et la réforme des administrations et sur les sources de I'innovation administrative. Malgré la grande diversité de formation et de carrières, les membres ont affiché un degréélevé d'unité de pensée concernant I'administration publique comme activité pratique dominée par les praticiens. C'est un monde de nuances où le changement se fait, certes, maisjamais exactement comme prévu et rarement sous la gouverne d'une théorie.  相似文献

There has been a large increase in the number of tooth colored restorations "white fillings" placed in recent years. An increased demand from the public for more aesthetic dental restorations causes a potential problem for forensic dentists who may find the fillings difficult to identify and hence include in postmortem odontograms. This has implications for the accuracy of dental identifications, particularly in situations where limited time is available for postmortem identification, e.g., mass casualty incidents. A new method for the detection of composite restorations is presented. Quantitative Light-induced Fluorescence (QLF) is a technique currently employed to detect small changes in enamel mineral content. An experiment was conducted to determine if the technique would afford a greater degree of contrast between composite and enamel and thus enable the accuracy of composite identification in enamel. Twenty-four previously extracted human premolars were gently cleaned with pumice and wet-and-dry paper. Twelve were subsequently randomly selected and restored on their buccal surfaces with Spectrum (a composite) following manufacturer's instructions. No attempt was made to color match the teeth and all were filled with shade B3. Twelve teeth were left unrestored. QLF and normal white light images were taken of both restored and non-restored surfaces with teeth wet and then dried. Ten forensic dentists were asked on two separate occasions (one month between each attempt) to indicate whether or not they thought the surface was: a) restored or b) unrestored. Results indicate that forensic dentists detected a significantly higher proportion (p<0.005) of filled surfaces with QLF.  相似文献

The postmortem concentrations of citalopram in blood, bile, liver, and vitreous humour were investigated in 14 cases using a specially developed high performance liquid chromatography assay. Concentrations from drug and non-drug related deaths were categorized to determine a postmortem therapeutic and toxic range. Therapeutic citalopram concentrations for blood, bile, liver, and vitreous humour ranged to 0.4 mg/L, 2.1 mg/l, 6.6 mg/kg, and 0.2 mg/L, respectively. In one potentially fatal response to citalopram, concentrations were 0.8 mg/L, 6.0 mg/L, 0.3 mg/L for blood, bile and vitreous humour, respectively.  相似文献

The paper re-assesses South Korean unification narratives in the context of territory and critical approaches to territory. From this, the paper identifies a set of underlying assumptions and expectations of South Korean government and civil society. The paper explains why division and unification are commonly assumed as a zero-sum relationship and primarily based on a bounded and homogenous understanding of spatiality and territory. From this, the paper indicates how alternative conceptions of space, networks and territory might be used to recast the site and nature of Korean territorial unification.  相似文献

Abstract

This paper focuses on the relationship between national security and environmentalism in South Korea. The 2009 South Korean Presidential Committee on Green Growth set a long-term vision for South Korea to ‘go green’. This is promoted as a new state-led development paradigm and a response to new global security risks. The paper identifies official and unofficial contested narratives on development, environmentalism and national security. By focusing on civil society movements, the paper identifies challenges to the exclusionary realist and liberal institutional approaches to South Korea's Green Growth initiative. These alternative discourses of national security are unpacking and reconstructing the relationship between development and environmentalism through the question of who defines ‘national security’ and for whose interests.  相似文献

Abstract:  The inclusion of radio-frequency identification (RFID)-tags within dental prostheses has been suggested as means of effectively labeling such devices and permitting rapid and reliable identification of the wearer. Previous studies have suggested that patients will accept denture labeling and recognize the need for such systems. However, they demand systems that are aesthetic, durable, and secure. One concern over the use of RFID-tags is that they could be scanned by third parties without the patient's knowledge. This study categorizes the scanning patterns of RFID-tags both in vitro and in vivo to provide data for patients for the consent process and for forensic dentists to ensure that they are scanning prostheses optimally. The results demonstrate that the RFID chips can only be read when the interrogator is in close proximity to the denture and thus should alleviate any concerns over privacy issues. However, evidence obtained from both the literature and experiments suggests that authorities must agree upon a unified standard for chip and reader specifications and protocols in order to avoid cases in which RFID-tags may fail to be read by an incompatible reader.  相似文献
