城市经济学发展历程研究综述

城市经济学（urban economic）是以城市这一独特的空间组织结构为研究对象的经济学科,与区域经济学（Regional Economics）、新经济地理学（newgeo graphyeconomic;）等学科同属于空间经济学（spatial economy）,与这些学科关系极为密切。在对城市经济学的形成历程、理论渊源、研究对象和与其他学科的关系进行回顾的基础上,最后对城市经济学的未来发展方向进行分析。     

A systematic review of psychosocial interventions for suicidal adolescents

Suicide is a leading cause of death for young people and rates of serious suicidal thoughts are even higher. Due to these high rates and potential harm to youth, effective interventions are necessary. The purpose of this systematic review was to determine the impact of interventions designed for suicidal adolescents. Both quasi-experimental and experimental designs in the published and unpublished literature were included, and a total of 17 studies were located. According to meta-analysis, intervention group participants were slightly less likely to have suicidal and self-harm events than control group participants. However, when studies assessed outcome at a later period than immediately after intervention, experimental group participants were slightly more likely to have suicidal and self-harm events than control group participants. For studies that measured suicidal ideation at posttest, intervention group participants were slightly less likely to report suicidal ideation than control group participants, both at posttest and at follow-up. These contradictory findings are explored and discussed.     

Lead Time Management through Expediting in a Continuous Review Inventory System

We consider a continuous review inventory system where delivery lead times can be managed by expediting in‐transit orders shipped from the supplier. First, we propose an ordering/expediting policy and derive expressions for evaluating the operating characteristics of such systems. Second, using extensive numerical experiments, we quantify the benefits of such an expediting policy. Third, we investigate a number of managerial issues. Specifically, we analyze the impact of the number of expediting hubs and their locations along the shipment network on the performance of such systems and offer insights into the design of the shipment network. We show (i) a single expediting hub that is optimally located in a shipment network can capture the majority of cost savings achieved by a multi‐hub system, especially when expediting cost is not low or demand variability is not high; (ii) when expediting time is proportional to the time to destination, for small‐enough or large‐enough demand variations, a single expediting hub located in the middle of the shipment network can capture the majority of cost savings of an optimally located hub; and (iii) in general, hubs close to the retailer significantly drive down costs, whereas hubs close to the supplier may not offer much cost savings.     

生殖性克隆的伦理与法律审视

克隆技术是20世纪人类社会的突破性技术革命成果之一,这种技术的出现使得人们在传统两性生殖方式外多了一种选择,即无性生殖方式。这种技术一旦运用于人类社会就会打破人类几千年来形成的伦理观念和法律制度,会引发众多的伦理和法律问题：生殖性克隆会打破传统生育模式,造成社会关系的混乱,损害人的尊严,造成对人和社会的伤害。因此从伦理和法律上否定生殖性克隆技术的运用是十分必要的。

十年来荀子政治哲学研究的回顾与展望

十年来,荀子政治哲学研究渐渐成为荀学研究的一个中心.挖掘分析荀子礼学的政治哲学内涵、孟荀异同的政治哲学内涵、荀子思想内在张力的政治哲学内涵,是研究的三个重心.然而,由于这个中心尚处于初建阶段,研究还存在泛化现象,政治哲学的议题常常被中西对比、孟荀冲撞、主客观差异等面相所遮蔽.今后,荀子政治哲学研究应加大学习借鉴西方政治哲学所已取得的成果特别是其中的客观精神的力度,直面现实,进一步集中并深化问题意识,力争为中国问题提供富有想像力和操作性的解决框架.

从特别减轻到违宪审查——以许霆案为样本的分析

许霆案的初审判决,基本上是一个严格规则主义的判决。其之所以演变成为一个公共事件,完全是律师的专业运作、学者的推波助澜、民意的偏执率性对司法裁决共同夹击所致。本案的重审判决,在事实和定性不变的情况下,适用刑法第63条规定的特别减轻制度,将初审的量刑结果进行了大幅度的削减。这一做法虽然满足了民众的隐性期望,却损害了刑事法治的应有权威,更显现不受羁束的刑事自由裁量权的可怕威力。事实上,许霆案的症结,不在司法层面,而在立法层面。因此,求诸于刑法中的特别减刑制度,并不能为解决类似案件提供一个可行的方案。只有建立常规性的违宪审查制度,对刑事立法规范进行合宪性审查,才能彻底解决因＂立法不公＂而导致的＂司法不公＂问题。     

“欧事研究会”述评——纪念辛亥革命100周年

辛亥革命最大的成果是建立了中华民国,但是中国社会的封建势力依然强大.许多革命党人对当时形势的认识多有不同,尤其在如何深入反对专制政治和独裁统治的问题上,孙中山与黄兴这两位辛亥革命元勋也是亲密战友之间,所主张的策略方针就存在很大分歧,最终导致两人的分手甚至组织上的分裂.文章通过对“欧事研究会”活动的分析,认为黄兴等人主张和努力的议会民主,虽然不无道理,但西方的政党政治方案,显然无法在20世纪的中国实现,但其宣传的一些主张,对后来新文化运动兴起,还是发生了积极的作用.
