The purpose of this study was to identify empirically, for the first time in France, the prevalence of adolescent weapon carrying with particular focus on the contribution of a broad range of social bonding, strain, social learning, and sociodemographic predictors. A multivariate logistic regression model was conducted using a backward elimination procedure to identify the significant predictors of weapon carrying controlling for age, gender, and SES in a sample of 12,706 French youth aged 11–19 years. Results revealed that the odds of weapon carrying increased among adolescents who suffered from past victimization, who had a negative relationship with their mother, and who repeated a grade at school. Moreover, holding pro-delinquent beliefs and having delinquent peers also increased the odds of weapon carrying. Our findings highlight the importance of the interpersonal and social context when examining the determinants of weapon carrying and showed a unique contribution of components of social bonding, strain, and social learning in weapon carrying among adolescents.  相似文献

Native species of trees and shrubs contribute significantly to farmers' livelihoods by supplying food, medicinal products, fodder, and wood. In the case study reported in this article, this contribution to farmers' annual revenue varied from 26 per cent to 73 per cent, and was as high as US$ 650 a year for households for which agroforestry products were the primary source of revenue. Household consumption was not quantified in the study, but farmers' comments confirmed that native trees also played an important role in assuring food security, especially in the ‘hunger period’ when grain stores are low and farmers are waiting for the next harvest.  相似文献

The authors report on a macroscopic and microscopic study of human mandible bone lesions achieved by a single-blade knife and a hatchet. The aim of this work was to complete the previous data (scanning electron microscopy analysis of bone lesions made by a single-blade knife and a hatchet, on human femurs) and to compare the lesions of the femur with those of the mandible. The results indicate that the mandible is a more fragile bone, but the features observed on the mandible are quite similar to those previously observed on the femur. This work spells out the main scanning electron microscopy characteristics of sharp (bone cutting) and blunt (exerting a pressure on the bone) mechanisms on human bone. Weapon characteristics serve to explain all of these features.  相似文献

This article investigates brand architecture by analyzing stakeholder perceptions of brand images when a new joint brand is created for the existing brands of three arts organizations. The theoretical framework is based on previous literature on brand architecture and brand image. The empirical study is based on a quantitative, 418-respondent survey among stakeholders of these three arts organizations. The study makes two major theoretical contributions. First, the results show that the new joint brand can be endorsed by the existing sub-brands, contrary to brand-architecture literature. Second, even in the case of a new brand, stakeholders perceive the functional attributes as important.  相似文献

ABSTRACT

The implementation of e-government aims at simplifying and improving the relationships and transactions between public administrations and their users or customers. In this vein, the objective of this work is to analyze the factors that promote the development of e-government in the national governments of 192 countries worldwide, differentiating between developed and developing countries. Our findings emphasize that the development of e-government requires that countries have a degree of economic development that enables their citizens to have a certain standard of living, both economic and cultural, as well as important internal government reforms which promote administrative effectiveness. Once these essential factors are fulfilled, the national government's online presence is favored by governments that rule with a majority in their parliaments and with an important fiscal capacity.  相似文献

A 43‐year‐old full‐term pregnant woman (gravida 2, para 1, medical history of gestational diabetes mellitus) developed a sudden and malignant hypertension with hemoptysis, sweat, and tachycardia during a scheduled C‐section. A dead newborn was delivered and was successfully resuscitated. The mother died after resistant cardiac arrest. Autopsy and pathological analyses revealed an acute pulmonary edema and a necrotic and hemorrhagic voluminous tumor of the left adrenal gland, which was a pheochromocytoma. Pheochromocytoma is a rare tumor of the adrenal glands which secretes catecholamines. In pregnant women, its symptoms can mimic gestational hypertension, preeclampsia or eclampsia, and gestational diabetes mellitus. The gestational diabetes mellitus was presumed to be a symptom of the pheochromocytoma, and cardiopulmonary failure the result from the necrosis of the tumor provoked by gravid uterus compression. From a medico‐legal point of view, the tumor could not have been suspected during the pregnancy.  相似文献

Abstract: The aim of this study was to establish a prediction formula to allow for the determination of sex among the southeastern French population using dental measurements. The sample consisted of 105 individuals (57 males and 48 females, aged between 18 and 25 years). Dental measurements were calculated using Euclidean distances, in three‐dimensional space, from point coordinates obtained by a Microscribe. A multiple logistic regression analysis was performed to establish the prediction formula. Among 12 selected dental distances, a stepwise logistic regression analysis highlighted the two most significant discriminate predictors of sex: one located at the mandible and the other at the maxilla. A cutpoint was proposed to prediction of true sex. The prediction formula was then tested on a validation sample (20 males and 34 females, aged between 18 and 62 years and with a history of orthodontics or restorative care) to evaluate the accuracy of the method.  相似文献

The objective of this paper is to analyze the relation between the concept of the Rule of Law and the culture of legality from a compared approach in order to establish the scope and limitations of explanations that are based in cultural factors. More specifically, we are interested in comparing the scope and limitations of culture-based explanations on why the Rule of Law prevails in certain countries: these explanations are centered in the construction of wide agreements between social actors and the control by civil society. Also we consider equally important the comparing of different definitions of culture of legality and the strategies and instruments that allow its construction. For this purpose we will center, specially, in the experiences of Hong Kong, Palermo and Bogotá.  相似文献

Abstract

This article contributes to a pragmatist analysis of pricing and valuation through an account of the production of closing prices at the Paris Bourse. The Paris Bourse is an electronic stock exchange and the actors in charge of its technological configuration often need to face concerns about the quality of the prices that the configuration produces. Closing prices are particularly important because they constitute references that circulate widely. The author analyses how a problem of representativeness of closing prices was raised in the late 1990s and how several techniques aimed at solving it. In order to deal with this problem of representativeness, the author proposes the consideration of prices as signs in a pragmatist manner. Adapting Charles S. Peirce's theory of the sign to the study of prices, the author concentrates attention on the material display of prices, on their capacity to stand as traces of some event, and on the way they may suit a set of calculative conventions.  相似文献
