在问题类型划分方法的视野下,犯罪概念问题应该属于纯粹刑法学问题中的解释选择问题,但刑法学界以往有关犯罪概念的讨论却大多将其作为刑法问题中的价值判断问题。由于未能妥当确定犯罪概念的问题类型,从而使学界有关犯罪概念的讨论未能达成最低限度的学术共识。作为纯粹刑法学问题中的解释选择问题,形式与实质相结合的混合犯罪概念不存在被替代的必要性,而犯罪概念也不应被规定在刑法典中。 相似文献

Bayesian acceptance sampling plans, which utilize prior information on the process variation, can be employed as an alternative to conventional types of plans for taking decisions on the disposition of submitted lots. A special type of double sampling inspection plans by attributes with small acceptance numbers using Bayesian methodology is presented in this paper emphasizing its significance over small acceptance number single sampling plans. The procedures for designing such sampling plans for specified degree of discrimination which would ensure protection to the producer and consumer are discussed with illustrations under the conditions for the application of gamma-Poisson distribution. 相似文献

“广州城市生活垃圾治理”课题组 《广州大学学报(社会科学版)》2014,(8):44-50
现代城市垃圾治理是一项复杂的系统工程。在城市垃圾中,生活垃圾所占比重大、与民众联系密切且处理阻力大,对城市生活垃圾治理的战略设计已成为城市管理者面临的最大难题之一。作为我国重要中心城市的广州,也正面临形势严峻的"垃圾围城"之困,自2012年开启新一轮城市生活垃圾综合治理以来,在有创新、有收获的同时也遇到了新的挑战。为进一步深化城市生活垃圾治理工作,广州应准确把脉顶层制度难"落地"、流程运行难系统、民众习惯难转变等现实症结,科学设计生活垃圾的多元共治路径,实现挑战与机遇的对接,为我国城市生活垃圾的治理树立标杆,助推开创城市垃圾治理的新局面。 相似文献

We study multiple-class classification problems. Both ordinal and categorical labeled cases are discussed. The common approaches for multiple-class classification are built on binary classifiers, in which one-versus-one and one-versus-rest are typical approaches. When the number of classes is large, then these binary-classifier-based methods may suffer from either computational costs or the highly imbalanced sample sizes in their training stage. In order to alleviate the computational burden and the imbalanced training data issue in multiple-class classification problems, we propose a method that has competitive performance and retains the ease of model interpretation, which is essential for a prognostic/predictive model. 相似文献

In this paper, we propose a multiple deferred state repetitive group sampling plan which is a new sampling plan developed by incorporating the features of both multiple deferred state sampling plan and repetitive group sampling plan, for assuring Weibull or gamma distributed mean life of the products. The quality of the product is represented by the ratio of true mean life and specified mean life of the products. Two points on the operating characteristic curve approach is used to determine the optimal parameters of the proposed plan. The plan parameters are determined by formulating an optimization problem for various combinations of producer's risk and consumer's risk for both distributions. The sensitivity analysis of the proposed plan is discussed. The implementation of the proposed plan is explained using real-life data and simulated data. The proposed plan under Weibull distribution is compared with the existing sampling plans. The average sample number (ASN) of the proposed plan and failure probability of the product are obtained under Weibull, gamma and Birnbaum–Saunders distributions for a specified value of shape parameter and compared with each other. In addition, a comparative study is made between the ASN of the proposed plan under Weibull and gamma distributions. 相似文献

Retirement is a complex life transition. Women’s retirement, like their work lives, may be further complicated, for example, by family or financial obligations; they may feel forced to retire or to continue working or feel they have the choice to do so. This study examines the role of voluntary versus involuntary retirement or continued work participation among retirement-age women; specifically, the relationships between choice, work status, and well-being. Compared to women forced to retire, women who chose retirement or continuing to work had higher levels of life satisfaction. Findings highlight the importance of examining retirement within the life course context. 相似文献

近年来,我国农业保险快速发展,在保费收入、保障范围和参保农户数量等指标上都取得了举世瞩目的成绩。与此同时,保障水平不高、农业保险“不解渴、不顶用”也一直是各方反映的焦点之一。本文结合了福利经济学和保险经济学中的相关理论,遵循“提高农业保险保障水平必须优化其财政补贴政策”的逻辑主线,对实施财政补贴政策是提升农业保险保障水平的前提条件、有效途径、有力举措和重要渠道进行了梳理和评析。最后,针对现有研究的不足,结合当前的时代背景,对该领域日后的研究重点进行了预测,并进一步探讨了其优化路径。 相似文献

The influence of competition level on referees’ decision-making was investigated. Referees’ decisions in 90 handball games (30 games X 3 competition levels) were observed in different situations related to the advantage rule, and 100 referees from two different levels of expertise were subsequently asked to offer explanations for the competition-level effects from the first part of the study. Results revealed that at the highest level of competition referees intervened less frequently with sporting sanctions, but more frequently with disciplinary sanctions. These effects were apparent mainly in immediate intervention situations and unsuccessful advantage situations, but not in successful situations. Referees explained these effects of competition level in terms of a player competence stereotype, in addition to referees’ different expertise across competition level. The implications of the findings for understanding how status-related stereotypes impact on intervention behavior are discussed. 相似文献
