Fate control and leisure attitudes

It has been suggested that attitudes toward leisure may be affected by one's perception of the ability to control life's consequences. Rotter's I‐E scale was used in the present study to measure the perceived locus of control and was correlated with the scales of Neulingers Leisure Attitude Inventory. Results indicated that positive attitudes toward leisure were generally more associated with an external than an internal locus of control, i.e., with the perception that one's fate is to a large degree personally uncontrollable. These results are explained in terms of the confounding influence of work/achievement orientation in the measurement of and in the relationship of those variables. Implications for leisure counseling, leisure education, and therapeutic recreation are also discussed.     

Local Democracy Ltd

Abstract

A number of European countries have witnessed a proliferation of local government enterprises in recent years. Norwegian local councillors are seemingly particularly exposed to this ‘enterprise fever’. Our article explores local governments' approaches to the political control of such companies. We observe a reluctance to intervene directly in the affairs of an enterprise, but there is a last-resort preparedness to take more resolute action. Lastly, in contrast to what the prototypical agency model postulates, we find that those who attach strong aspirations of increased capacity to the establishment of companies appear to lack trust in the same companies' performance capability.     

煮糖过程建模

对某个系统进行有效的控制，必须要定量、准确地分析该系统的特性，弄清表征该系统特性的各物理量之间的关系，而这种关系的定量表达式，被称为该系统的数学模型。文章运用蔗糖结晶理论，建立了比较合理的数学模型，这种模型建立的要点在于结晶质量的计算。

论产权制度变迁与基层民主的互动

随着我国产权制度变革,区域的经济与社会结构已悄然发生变迁.要保持区域制度变迁的"比较制度优势",就必须进一步推进地方政府体制变迁,满足区域民众日益增长的民主需求,建构基层民主秩序.基层民主的制度安排的价值并不在于选举制度本身,而是在于从根本上改变传统制度结构中"精英主导和民众缺位",逐步实现制度变迁过程中政治精英、经济精英、民众的和谐互动.

Optimal regime switching and threshold effects

We consider a general control problem with two types of optimal regime switch. The first one concerns technological and/or institutional regimes indexed by a finite number of discrete parameter values, and the second features regimes relying on given threshold values for given state variables. We propose a general optimal control framework allowing to derive the first-order optimality conditions and in particular to characterize the geometry of the shadow prices at optimal switching times (if any). We apply this new optimal control material to address the problem of the optimal management of natural resources under ecological irreversibility, and with the possibility to switch to a backstop technology.
