制度风险的法律维度: 突破非物质文化遗产保护的瓶颈

以风险理论审视非物质文化遗产的现行法律制度,根据风险产生根源不同,非物质文化遗产保护的制度风险会表现为制度运转失灵风险、制度功能偏差风险和公平性缺失风险。化解制度风险,形成制度风险的维度,不可基于同一个标准,而是需要在大的框架之下论及制度风险的法律管控,需要有针对性地创构"建立私权,善用公权"的多元法律控制体系,并在体系内引入技术规制,创设"非物质文化遗产权",推动民间习惯法与法律制度、公法与私法的互动式发展。     

Estimation of geodesic tortuosity and constrictivity in stationary random closed sets

We investigate the problem of estimating geodesic tortuosity and constrictivity as two structural characteristics of stationary random closed sets. They are of central importance for the analysis of effective transport properties in porous or composite materials. Loosely speaking, geodesic tortuosity measures the windedness of paths, whereas the notion of constrictivity captures the appearance of bottlenecks resulting from narrow passages within a given materials phase. We first provide mathematically precise definitions of these quantities and introduce appropriate estimators. Then, we show strong consistency of these estimators for unboundedly growing sampling windows. In order to apply our estimators to real data sets, the extent of edge effects needs to be controlled. This is illustrated using a model for a multiphase material that is incorporated in solid oxide fuel cells.     

Ending Sexual Harassment: Protecting the Progress of #MeToo

ABSTRACT

How can we best protect and safeguard the progress of the #MeToo movement? This article presents 11 reforms designed to ensure the movement’s drive toward justice. These fall into three areas. The first concern process reforms designed to (a) protect all those involved—accusers and the accused—in investigations of sexual harassment, (b) end differential treatment of those found guilty, and (c) ensure punishments are commensurate with the crime and proportional in terms of other transgressors. The second set of reforms focus on transparency of the process, including clarifying (a) how to file charges, (b) who makes decisions, (c) relevant public information on how charges and procedures are followed, (d) what transgressions result in which punishments, and (e) how complaints are investigated to protect the rights and privacy of all. Finally, I address cultural issues that address (a) our portrayal of women, (b) our societal attempts to prepare young people so they can better protect themselves, and (c) attempts to encourage bystanders to intervene in the face of sexual harassment of others.     

考虑零售商质量控制和风险规避的供应链网络均衡研究

研究零售商质量控制和供应链成员风险规避背景下供应链网络均衡问题。应用条件风险值度量风险规避程度，利用变分不等式理论描绘供应链参与者的最优经济行为，设计供应链网络均衡模型，考虑风险规避和质量控制策略对均衡的影响，证明均衡解存在且唯一，并运用Levenberg-Marquardt算法求解均衡模型。最后对重要参数进行数值分析，揭示质量控制和风险规避对供应链均衡解以及参与者条件风险值的影响。研究表明：供应链参与者越规避风险越有利于产品质量水平的提高，风险规避程度的加深会降低制造商或零售商自身的CVaR，同时增大对方的CVaR，对因产品合格率提高带来的利益而言，制造商所得优于零售商。     

Formal governance,interfirm coordination,and performance in partnerships: An empirical investigation of a mediation model

This study investigates the extent to which formal governance mechanisms such as contracts and equity ownership affect interfirm coordination and partnership performance. We analysed data from a survey of 301 Korean firms to show that interfirm coordination partially mediates the relationship between contract completeness, defined as the extent to which a contract specifies task operations and contingencies, and partnership performance. Furthermore, we find that more complete contracts can attenuate the negative effects of equity ownership on coordination, and that this effect is particularly strong when partner tasks are interdependent and relational norms are weak.     

The African Evaluation Guidelines: 2002. A checklist to assist in planning evaluations, negotiating clear contracts, reviewing progress and ensuring adequate completion of an evaluation

A review of the US ‘program evaluation standards’ (PES), undertaken in a series of workshops and meetings of networks of evaluators in Africa, resulted in modifications to those standards. The result was presented to a plenary session of the Inaugural Conference of the African Evaluation Association in September 1999, attended by over 300 evaluators from 35 countries. The AfrEA Conference decided that a systematic effort should be made to produce a list of African evaluation guidelines, similar to the PES, and that this checklist should be reviewed by national evaluation associations and networks in Africa and field tested in several countries. Ten national and regional networks and associations suggested modifications to the text and endorsed the final version of the guidelines.
