民法中请求权概念之辨析

一、请求权概念辨析的必要性 在民法学界,请求权是出现频率较高的概念,对其进行归纳,主要集中于四个领域,以下通过分别阐述,说明辨析请求权概念的必要性. (一)请求权在民法基础理论领域 在民事权利这一体系中,请求权是作为权利的一种类型出现的,它被定义为"权利人可以要求他人为一定行为或不为一定行为的权利."①但从这一定义中并不能使人获得明确的教义:     

The role of law in public health preparedness: opportunities and challenges

We report the results of a study designed to assess and evaluate how the law shapes the public health system's preparedness activities. Based on 144 qualitative interviews conducted in nine states, we used a model that compared the objective legal environment with how practitioners perceived the laws. Most local public health and emergency management professionals relied on what they perceived the legal environment to be rather than on an adequate understanding of the objective legal requirements. Major reasons for the gap include the lack of legal training for local practitioners and the difficulty of obtaining clarification and consistent legal advice regarding public health preparedness. Narrowing the gap would most likely improve preparedness outcomes. We conclude that there are serious deficiencies in legal preparedness that can undermine effective responses to public health emergencies. Correcting the lack of legal knowledge, coupled with eliminating delays in resolving legal issues and questions during public health emergencies, could have measurable consequences on reducing morbidity and mortality.     

The relationship of imagery and mental practice to learning law enforcement skills

Visualization and mental rehearsal/ practice have beem empirically evaluated in the athletic area for many years and found to be viable forms of performance enhancement. Gross motor skills and certain psychological/physiological dysfunctions are also susceptible to improvement through use of these techniques. A general overview of these concepts is presented as well as potential applications in the law enforcement context.     

Posner versus Kelsen: the challenges for scientific analysis of law

Law & economics scholars claim, among other things, to provide explanations of how law impacts behaviour. The aim of this article is to shed light on the conceptual and methodological difficulties related to analysis of the impact that law has on behaviour. The analysis advanced in the paper takes as its starting point a commentary on Richard Posner’s interpretation of Hans Kelsen’s pure theory of law. The work of Kelsen is treated as a meta-theoretical analysis that reveals some of the presumptions of theoretical approaches to law that claim to be scientific and, in particular, that claim to scientifically analyse the law’s influence on behaviour. The article concludes with a methodological proposal on how to approach the identified methodological challenges and conceptual tensions that law & economics contends with.
