Political scientists have long classified systems of government as parliamentary or presidential, two-party or multiparty, and so on. But such distinctions often fail to provide useful insights. For ...example, how are we to compare the United States, a presidential bicameral regime with two weak parties, to Denmark, a parliamentary unicameral regime with many strong parties?Veto Playersadvances an important, new understanding of how governments are structured. The real distinctions between political systems, contends George Tsebelis, are to be found in the extent to which they afford political actors veto power over policy choices. Drawing richly on game theory, he develops a scheme by which governments can thus be classified. He shows why an increase in the number of "veto players," or an increase in their ideological distance from each other, increases policy stability, impeding significant departures from the status quo.
Policy stability affects a series of other key characteristics of polities, argues the author. For example, it leads to high judicial and bureaucratic independence, as well as high government instability (in parliamentary systems). The propositions derived from the theoretical framework Tsebelis develops in the first part of the book are tested in the second part with various data sets from advanced industrialized countries, as well as analysis of legislation in the European Union. Representing the first consistent and consequential theory of comparative politics,Veto Playerswill be welcomed by students and scholars as a defining text of the discipline.
From the preface to the Italian edition:
"Tsebelis has produced what is today the most original theory for the understanding of the dynamics of contemporary regimes. . . . This book promises to remain a lasting contribution to political analysis."--Gianfranco Pasquino, Professor of Political Science, University of Bologna
Perhaps no kind of regulation is more common or less useful than mandated disclosure-requiring one party to a transaction to give the other information. It is the iTunes terms you assent to, the ...doctor's consent form you sign, the pile of papers you get with your mortgage. Reading the terms, the form, and the papers is supposed to equip you to choose your purchase, your treatment, and your loan well.More Than You Wanted to Knowsurveys the evidence and finds that mandated disclosure rarely works. But how could it? Who reads these disclosures? Who understands them? Who uses them to make better choices?
Omri Ben-Shahar and Carl Schneider put the regulatory problem in human terms. Most people find disclosures complex, obscure, and dull. Most people make choices by stripping information away, not layering it on. Most people find they can safely ignore most disclosures and that they lack the literacy to analyze them anyway. And so many disclosures are mandated that nobody could heed them all. Nor can all this be changed by simpler forms in plainer English, since complex things cannot be made simple by better writing. Furthermore, disclosure is a lawmakers' panacea, so they keep issuing new mandates and expanding old ones, often instead of taking on the hard work of writing regulations with bite.
Timely and provocative,More Than You Wanted to Knowtakes on the form of regulation we encounter daily and asks why we must encounter it at all.
A guide to the various models and methods to multicriteria decision-making in conditions of uncertainty presented in a systematic approach Multicriteria Decision-Making under Conditions of ...Uncertainty presents approaches that help to answer the fundamental questions at the center of all decision-making problems: "What to do?" and "How to do it?" The book explores methods of representing and handling diverse manifestations of the uncertainty factor and a multicriteria nature of problems that can arise in system design, planning, operation, and control. The authors-noted experts on the topic-and their book covers essential questions, including notions and fundamental concepts of fuzzy sets, models and methods of multiobjective as well as multiattribute decision-making, the classical approach to dealing with uncertainty of information and its generalization for analyzing multicriteria problems in condition of uncertainty, and more. This comprehensive book contains information on "harmonious solutions" in multiobjective problem-solving (analyzing <X, F> models), construction and analysis of <X, R> models, results aimed at generating robust solutions in analyzing multicriteria problems under uncertainty, and more. In addition, the book includes illustrative examples of various applications, including real-world case studies related to the authors' various industrial projects. This important resource: Explains the design and processing aspect of fuzzy sets, including construction of membership functions, fuzzy numbers, fuzzy relations, aggregation operations, and fuzzy sets transformations Describes models of multiobjective decision-making (<X. M> models), their analysis on the basis of using the Bellman-Zadeh approach to decision-making in a fuzzy environment, and their diverse applications, including multicriteria allocation of resources Investigates models of multiattribute decision-making (<X, R> models) and their analysis on the basis of the construction and processing of fuzzy preference relations as well as demonstrating their applications to solve diverse classes of multiattribute problems Explores notions of payoff matrices and fuzzy-set-based generalization and modification of the classic approach to decision-making under conditions of uncertainty to generate robust solutions in analyzing multicriteria problems Written for students, researchers and practitioners in disciplines in which decision-making is of paramount relevance, Multicriteria Decision-Making under Conditions of Uncertainty presents a systematic and current approach that encompasses a range of models and methods as well as new applications.
Although people who endorse conspiracy theories related to medicine often have negative attitudes toward particular health care measures and may even shun the healthcare system in general, conspiracy ...theories have received rather meager attention in bioethics literature. Consequently, and given that conspiracy theorizing appears rather prevalent, it has been maintained that there is significant need for bioethics debate over how to deal with conspiracy theories. While the proposals have typically focused on the effects that unwarranted conspiracy theories have in the public health context, Nathan Stout's recent argument concentrates on the impacts that such theories have at the individual level of clinical decision‐making. In this article, I maintain that duly acknowledging the impacts of conspiracy theories that raise Stout's concern does not require bioethics debate over the proper response to the influence of conspiracy theories in healthcare. Having evaluated two possible objections, I conclude by briefly clarifying the purported import of the response to Stout.
This analysis of the law's approach to healthcare decision-making critiques its liberal foundations in respect of three categories of people: adults with capacity, adults without capacity and adults ...who are subject to mental health legislation. Focusing primarily on the law in England and Wales, the analysis also draws on the law in the United States, legal positions in Australia, Canada, Ireland, New Zealand and Scotland and on the human rights protections provided by the ECHR and the Convention on the Rights of Persons with Disabilities. Having identified the limitations of a legal view of autonomy as primarily a principle of non-interference, Mary Donnelly questions the effectiveness of capacity as a gatekeeper for the right of autonomy and advocates both an increased role for human rights in developing the conceptual basis for the law and the grounding of future legal developments in a close empirical interrogation of the law in practice.
Aims
To examine hospital nurses’ perception of their actual and potential contribution to shared decision‐making about life‐prolonging treatment and their perception of the pre‐conditions for such a ...contribution.
Design
A qualitative interview study.
Methods
Semi‐structured face‐to‐face interviews were conducted with 18 hospital nurses who were involved in care for patients with life‐threatening illnesses. Data were collected from October 2018‐January 2019. The interviews were recorded, transcribed verbatim and analysed using thematic analysis by two researchers.
Results
Nurses experienced varying degrees of influence on decision‐making about life‐prolonging treatment. Besides, we identified different points of contact in the treatment trajectory at which nurses could be involved in treatment decision‐making. Nurses’ descriptions of behaviours that potentially contribute to shared decision‐making were classified into three roles as follows: checking the quality of a decision, complementing shared decision‐making and facilitating shared decision‐making. Pre‐conditions for fulfilling the roles identified in this study were: (a) the transfer of information among nurses and between nurses and other healthcare professionals; (b) a culture where there is a positive attitude to nurses' involvement in decision‐making; (c) a good relationship with physicians; (d) knowledge and skills; (e) sufficient time; and (f) a good relationship with patients.
Conclusion
Nurses described behaviour that reflected a supporting role in shared decision‐making about patients’ life‐prolonging treatment, although not all nurses experienced this involvement as such. Nurses can enhance the shared decision‐making process by checking the decision quality and by complementing and facilitating shared decision‐making.
Impact
Nurses are increasingly considered instrumental in the shared decision‐making process. To facilitate their contribution, future research should focus on the possible impact of nurses’ involvement in treatment decision‐making and on evidence‐based training to raise awareness and offer guidance for nurses on how to adopt this role.
摘要
目标
研究医院护士对延长生命治疗共同决策的实际贡献和潜在贡献的认识,以及对此类贡献前提条件的认识。
设计
定性访谈研究。
方法
对18名医院护士进行半结构化的面对面访谈,这些护士均参与了患有命危疾病患者的护理工作。收集2018年10月至2019年1月之间的数据。两名研究员对访谈内容进行录制、逐字转录和主题分析。
结果
护士对延长生命治疗决策有着不同程度的影响作用。此外,我们确定了护士在治疗过程中可以参与治疗决策的不同接触点。护士对可能促进共同决策行为的可描述为以下三个角色:检查决策质量、对共同决策进行补充和促进共同决策。履行本研究中确定角色作用的先决条件是:(a)护士之间以及护士和其他保健专业人员之间的信息传递;(b)对护士参与决策持积极态度的文化;(c)与医生的良好关系;(d)知识和技能;(e)充裕的时间;以及(f)与患者的良好关系。
结论
护士会说明能反映对患者延长生命治疗共同决策中起到支持作用的行为,尽管并非所有护士都会经历此类参与过程。护士可以通过检查决策质量、补充和促进共同决策来增强在共同决策过程中的作用。
影响
护士在共同决策过程中的作用越来越大。为促进他们的贡献,未来的研究应侧重于护士参与治疗决策的影响可能性,以及循证培训,以提高他们对于其如何发挥这一作用的认识并提供相关指导。
An authoritative graduate textbook on information choice, an exciting frontier of research in economics and finance Most theories in economics and finance predict what people will do, given what they ...know about the world around them. But what do people know about their environments? The study of information choice seeks to answer this question, explaining why economic players know what they know—and how the information they have affects collective outcomes. Instead of assuming what people do or don't know, information choice asks what people would choose to know. Then it predicts what, given that information, they would choose to do. In this textbook, Laura Veldkamp introduces graduate students in economics and finance to this important new research.The book illustrates how information choice is used to answer questions in monetary economics, portfolio choice theory, business cycle theory, international finance, asset pricing, and other areas. It shows how to build and test applied theory models with information frictions. And it covers recent work on topics such as rational inattention, information markets, and strategic games with heterogeneous information. * Illustrates how information choice is used to answer questions in monetary economics, portfolio choice theory, business cycle theory, international finance, asset pricing, and other areas * Teaches how to build and test applied theory models with information frictions * Covers recent research on topics such as rational inattention, information markets, and strategic games with heterogeneous information
