信息揭示过程延长与交易者策略变化

将经典的单期Kyle模型扩展到无限期,并假设私有信息有一个逐步揭示的过程,在这种更加接近现实的假设下,研究了线性均衡意义下知情交易者的交易策略。与经典Kyle模型相比,知情交易者的交易没有原来积极,信息优势的增加使得知情交易者的无条件期望收益增加。模型结果表明,如果知情交易者的信息有很好的隐藏性,那么私有信息揭示成公开信息需要的交易时期越长,市场的信息非对称性就越大,知情交易者就可以获得越多的收益。     

CLIENTS ROLE CHOICES: UNEXPLORED FACTORS IN INTERVENTION DECISIONS

The role of the client in social work interventions has not been extensively explored in the professional literature. However, the client role varies significantly in different models of care and carries vast differences in the expectations and behaviors required of clients in the process. Clients’ individual characteristics, preferences, and expectations make them better suited to some approaches than others. This paper explores the change in perspectives on consumers emerging in the field and analyzes client role factors in four intervention models. It will also discuss the “fit” between the client and the particular approach as well as implications for outcomes and evidence-based practice.     

同意的困境——基于以同意理论证成政府家长式干预的视角

在自由主义语境中,对政府家长式干预行为可行性的分析诉诸于对个人意愿真实性的探求,而同意理论作为个人意愿的有效表达方式成为家长主义者和反家长主义者论辩的重点。但是,由于同意本身所具有的局限性,使得通过诉诸于个人意愿的方式证成政府家长式干预行为的路径遭遇到了不可避免的困境。     

构建网络伦理的基本原则

网络化社会是人们的另类生存空间 ,网络主体的生存方式因数字化而表现出虚拟性、自主性、“非人性”等特征 ,这决定了其道德运行方式、道德评价方式、道德的功能机制等都有着与现实社会中不同的特点 ,因此有必要以网络主体道德活动方式的特点为依据 ,来寻求新的伦理原则 ,作为构建网络伦理的理性基础。根据网络主体道德活动方式的特点可知 ,网络伦理的基本原则应当主要包括无害原则 ,自主原则 ,知情同意原则和公正原则     

上海证券交易所A股市场隐藏性交易实证研究

以上海证券交易所A股市场所有股票的高频交易数据为样本,验证了中国股票市场中的隐藏性交易行为,证实了纯指令驱动市场中也存在隐藏性交易现象。但与纽约证券市场的知情交易者将交易指令集中于中等规模的交易以隐藏自己的知情者身份有所不同,中国股票市场中的知情交易者在市场上升时期将交易指令分解成较小规模的交易进行成交,而在市场下降时期则倾向于选择较大规模的交易指令,这表明不同的市场交易机制和外部市场环境对知情交易者提交策略具有不同的影响。     

患者权利的法律保护——以医疗知情同意权为视角

医疗知情同意以法律制度的形式详细地规定在《侵权责任法》第55条和56条中。医疗知情同意无非就是医院讲清楚其是如何治疗、怎样用药以及手术过程中存在哪些可以预知的风险,本是尊重患者知情权和选择权的制度安排。但是在司法实践中,由于医患之间缺乏信任,医疗知情同意制度被认为是医生推卸责任的"保护伞"。减少知情同意环节引发的纠纷,充分发挥医疗知情同意制度的作用,保护医患双方的权益,离不开医患双方的共同努力。     

论违反医疗告知义务的侵权责任

我国《侵权责任法》将＂信息告知＂领域与＂诊断治疗＂领域的侵权责任进行了区别规定,在第55条中对违反医疗告知义务的侵权责任作了专门规定。该责任较之于＂诊断治疗＂领域的侵权责任存在着极大的特殊性,其法理基础在于保障患者的自主决定权,而归责原则依然是一般的过错责任原则。在侵权行为认定时,需坚持＂患者标准＂及主客观相结合的标准。在判定因果关系时,也需将单纯的知情权受侵害作为其责任构成要件中的＂损害＂来理解。     

工程活动中公众的伦理责任分析

工程活动与公众之间是密不可分的关系：工程的根本目的在于造福公众,公众是工程利益相关者,公众福祉是评价工程是否具有道德正当性的终极标准。公众在工程活动中应当承担理解工程、参与工程与监督工程的伦理责任。实现公众的伦理责任,需充分保障公众在工程活动中的知情同意权,完善公众在工程活动中的参与机制与监督机制,提高公众的工程技术素质与伦理责任意识。     

What is a Vote Worth? A Focused Inquiry to Scaffold Elementary Historical Thinking

Abstract

Meaningful source work is at the heart of social studies learning, but often a tall order for elementary-aged students. In this article, the authors describe the construction and implementation of a fifth grade inquiry on the Suffrage Movement using a focused version of the Inquiry Design Model (IDM) Blueprint. Using source analysis scaffolds coupled with discussion and organizational tasks, students used primary and secondary sources to create complex evidence-based claims showing the intersection between First Amendment rights, civic engagement, and the Suffrage Movement. This focused inquiry supported meaningful application of learning to an informed civic action project.     

Prostitution of Young Persons

SUMMARY

Juvenile prostitution in the German welfare work is being interpreted as a peculiar behaviour which cannot be influenced by criminal law but by psychodynamic and social condition factors and motives. The public prostitution of adolescents largely takes place unaffected by criminal persecution. In view of the legislation in Germany, the regulations of criminal law have not had any decisive influence at juvenile prostitution. In Germany there exists a sufficient protection of children and adolescents. The current discussion about the expansion of the childhood definition of young people up to 18 years, and a de-legalization of agreed sexual actions between people under and over 18 years ignores a typical juvenile behaviour. A change in the situation of life of juvenile prostitutes by a legal intensification, as well as a change in behaviour through an anonymous sanction system like that of legislation, cannot be expected.
