行政许可案件判决方式研究

对于行政机关违法的许可行为 ,法院撤销该行为并不能自然恢复原告应当享有的许可权益。现行法律规定的判决方式存在局限性 ,单纯的撤销判决无法满足原告的诉讼请求 ,而履行判决不适用于多数许可案件。为此 ,法院应当对许可案件进行全面审查 ,可以要求行政机关按照法院意图重新作出许可行为 ,其作用在于防止行政机关规避法律的行为 ,弥补现行判决方式之不足

Intermediate inequality and welfare

We introduce a new centrist or intermediate inequality concept, between the usual relative and absolute notions, which is shown to be a variant of the α-ray invariant inequality measures in Pfingsten and Seidl (1997). We say that distributions x and y have the same (x, π)-inequality if the total income difference between them is allocated among the individuals as follows: 100π% preserving income shares in x, and 100(1−π)% in equal absolute amounts. This notion can be made as operational as current standard methods in Shorrocks (1983). Received: 13 May 1998/Accepted: 25 January 1999     

Higher Education Levels,Firms’ Outside Options and the Wage Structure

Abstract. We analyze the consequences of an increase in the supply of highly educated workers on relative and real wages in a search model where wages are set by Nash bargaining. A key insight is that an increase in the average education level exerts a negative externality on wages through its positive externality on the firms’ outside option. As a consequence, the real wage of all workers decreases in the short run. Since this decline is more pronounced for less educated workers, wage inequality increases. In the long‐run a better educated work force induces firms to invest more in physical capital. Wage inequality and real wages of highly educated workers increase while real wages of less educated workers may decrease. These results are consistent with the US experience in the 1970s and 1980s. Based upon differences in legal employment protection we also provide an explanation for the diverging evolution of real and relative wages in Continental Europe.     

从结论看方法：社会学研究的现实性维度思考——关于美国社会学者对中国社会分层研究的讨论*

本文以社会分层研究为例,指出面向现实是社会学研究科学性的根本保证,研究结论就是对现实的反映,而这种反映的真实程度又是由研究方法所决定的,方法的选择和实施则是由研究范式所指导的。范式、方法和结论最终统一在研究的现实性维度之上。     

Determining socio-demographic predictors of treatment dropout: results in a therapeutic community

This article presents a study of a number of socio-demographic factors that predict treatment dropout from a residential substance use disorder programme in Spain ( Proyecto Hombre Therapeutic Community). A sample of 430 patients (173 who completed treatment and 257 who dropped out of treatment) was assessed at entry to the therapeutic community programme in order to collect information on socio-demographic characteristics of the participants. According to the results obtained, factors that predicted treatment dropout included younger age, male gender and previous treatment history in the Proyecto Hombre therapeutic community. Patients with these characteristics were at significantly greater risk of dropping out of treatment. The implications of these results for further research and clinical practice are commented upon.     

Continuous Utility Functions Through Scales

We present here a direct elementary construction of continuous utility functions on perfectly separable totally preordered sets that does not make use of the well-known Debreu’s open gap lemma. This new construction leans on the concept of a separating countable decreasing scale. Starting from a perfectly separable totally ordered structure, we give an explicit construction of a separating countable decreasing scale, from which we show how to get a continuous utility map.      

Single cycle policies for the one-warehouse N-retailer inventory/distribution system

We address a multi-echelon inventory system with one-warehouse and N  -retailers. The demand at each retailer is assumed to be known and satisfied by the warehouse. Shortages are not allowed and lead times are negligible. Costs at each facility consist of a fixed charge per order and a holding cost. The goal is to determine single-cycle policies which minimize the average cost per unit time, that is, the sum of the average holding and setup costs per unit time at the retailers and at the warehouse. We propose a O(NlogN)$\mathrm{O}(N\log N)$ heuristic procedure to compute efficient single-cycle policies. This heuristic is compared with other approaches proposed by Schwarz, Graves and Schwarz and Muckstadt and Roundy. We carry out a computational study to test the effectiveness of the heuristic and to compare the performance of the different procedures. From the computational results, it is shown that the new heuristic provides, on average, better single-cycle policies than those given by the Muckstadt and Roundy method.
