Measures of individual risk attitudes and portfolio choice: Evidence from pension participants

We use a large non-student sample to test how distinct measures of risk-attitudes relate to each other, to demographic characteristics and to real-life risk taking in the financial domain. These measures, namely the Bomb Risk Elicitation Task (BRET), self-reported willingness to take risks in general, the choice in a hypothetical lottery, the score in the Domain Specific Risk-Taking (DOSPERT) scale, appear to be positively correlated and exhibit a certain degree of consistency. Furthermore, a subset of these measures is driven by similar demographic characteristics as such that males are more risk seeking and risk-aversion increases with age. Using extensive data on the retirement portfolios of the participants during the years 2008–2014, we find that all of these measures are positively correlated with the riskiness of individual portfolios. The self-reported willingness to take risks in general appears to be the most relevant measure in predicting actual risk-taking behavior.     

论刑罚资源的有效配置

对刑罚意义的不同理解以及对刑罚目的的不同追求直接决定着刑事制裁方式的选择。刑罚的目的是通过加重犯罪所需要的成本来制止犯罪,从而得到最佳的刑罚效益。在刑罚资源有限的前提下,如何选择有效的刑事制裁方式,以最合理、最小量的刑罚成本投入,最大限度获取刑罚效益,始终是一个难题。从刑罚经济分析的角度,研究犯罪与刑罚的关系,有助于实现刑罚资源的有效配置,促进刑事司法活动成本减少、效益增大,进而更好地惩治犯罪与预防犯罪。     

和谐视角观照下的幼儿适应行为

幼儿的适应行为是幼儿社会化的前奏，也是幼儿逐渐融入新环境的必备条件。在和谐视角观照下，影响幼儿不适应行为主要有三方面因素：幼儿身心发展不平衡、社会适应能力欠缺、自然适应能力薄弱。据此，教师和家长可依据 “和合观”、“和处观”以及“和生观”等培养策略来加强幼儿适应行为，从而促使幼儿自身身心、幼儿与社会以及幼儿与自然界的和谐共处。     

Selective Maintenance in System Reliability with Random Costs of Repairing and Replacing the Components

In this paper we consider the problem of determining the optimum number of repairable and replaceable components to maximize a system's reliability when both, the cost of repairing the components and the cost of replacement of components by new ones, are random. We formulate it as a problem of non-linear stochastic programming. The solution is obtained through Chance Constrained programming. We also consider the problem of finding the optimal maintenance cost for a given reliability requirement of the system. The solution is then obtained by using Modified E-model. A numerical example is solved for both the formulations.

Resiliency in the Aftermath of Repetitious Violence in the Workplace

Summary

The definition and occurrence of traumatic events is expanding and impacts everyone's lives in some way. The degree to which a violent event impacts an individual, a group, a workplace or the community varies. Unfortunately violent events are all too common. Businesses are realizing the significance of violence as a workplace problem and the varying degrees of trauma that has a devastating impact on employee retention, workplace functionality and personal well-being. The events can include industrial or natural disasters; worksite accidents; organizational changes; suicide; homicides; robbery; assault; threats of violence and even terrorism. How prepared an organization is varies and may be correlated with how resilient individuals and the entire workplace are after workplace violence/trauma. This article focuses on what workplace violence and trauma includes, the effects of repeat events, how resilient people are while trying to prevent additional events if possible in the workplace.     

A Realistic Path to Implementing China’s Budget Law

The core issue for the implementation of modern budget law is to optimize the satisfaction of society’s demand for public goods. The form of implementation mechanism that will best achieve this goal has thus become a major topic in the field of legal research. To go beyond the Anglo-Saxon budget model and construct a realistic path for the implementation of China’s budget law, this issue needs to be explored from the perspective of Chinese citizens in a way that safeguards the fundamental interests of the people and is premised on upholding and improving the People’s Congress system, so as to achieve a balance between internal and external budget allocation relationships. There are three routes to implementing China’s budget law: the political, the social, and the judicial. Under the first, citizens’ political identity interests are represented by deputies who oversee the budgetary powers of administrative bodies through the People’s Congress. Under the second, citizens individually or collectively participate, influence or even decide the allocation of public economic resources through dialogue, negotiation, reasoning and argument with the responsible budgetary agency in the course of the budget’s compilation, examination and approval, execution and supervision. Under the third, the establishment of a system for budgetary litigation allows citizens to participate in and supervise the implementation of the budget law, individually or collectively. This provides judicial security for the law’s implementation. These three realistic implementation routes represent the dialectical unity of concerted institutional effort aimed directly at effective implementation of budget law. Judicial interpretations of budget law implementation indicate the importance and urgency of promoting national governance capacity through reform of the legal systems governing finance and taxation. This explains the significant role of finance and taxation law in national governance.

Adaptive agent-based manufacturing control and its application to flow shop routing control

The manufacturing industry is currently facing unprecedented challenges from changes and disturbances. The sources of these changes and disturbances are of different scope and magnitude. They can be of a commercial nature, or linked to fast product development and design, or purely operational (e.g. rush order, machine breakdown, material shortage etc.). In order to meet these requirements it is increasingly important that a production operation be flexible and is able to adapt to new and more suitable ways of operating. This paper focuses on a new strategy for enabling manufacturing control systems to adapt to changing conditions both in terms of product variation and production system upgrades. The approach proposed is based on two key concepts: (1) An autonomous and distributed approach to manufacturing control based on multi-agent methods in which so called operational agents represent the key physical and logical elements in the production environment to be controlled – for example, products and machines and the control strategies that drive them and (2) An adaptation mechanism based around the evolutionary concept of replicator dynamics which updates the behaviour of newly formed operational agents based on historical performance records in order to be better suited to the production environment. An application of this approach for route selection of similar products in manufacturing flow shops is developed and is illustrated in this paper using an example based on the control of an automobile paint shop.
