Is there life after degeneration? The organizational life cycle of cooperatives under a ‘grow‐or‐die’ dichotomy

This article provides an in‐depth, longitudinal analysis combining real‐time and retrospective data on a set of Mondragon's industrial cooperatives that are organized as international groups. We examine the life cycle of these international cooperative groups, which is expected to evolve differently to that of small‐ and medium‐sized cooperatives that operate exclusively on a local scale. The article is theoretically informed by the cooperative life cycle theory, as well as by recent insights from the degeneration and regeneration theses. Our analysis yields an intricate picture of the evolution of cooperatives faced with a ‘grow‐or‐die’ dichotomy. On the one hand, our findings reject the highly simplistic and deterministic view of the degeneration thesis by demonstrating that these cooperatives can mobilize resources to revitalize cooperative values and practices. On the other, we find that regeneration may not occur in a consistent, sequential fashion as the previous literature suggests, but rather degenerative and regenerative tendencies can occur simultaneously, even leading to long‐lasting, unresolvable situations. In light of this, the article asks future research to draw on power‐aware and politically informed approaches for further understanding of how cooperatives manage the tensions at each organizational stage of their life cycle, and of which organizational actors benefit, and how, from reversing some degenerative tendencies while maintaining others intact.

Perfect simulation for models of industry dynamics

In this paper we introduce a technique for perfect simulation from the stationary distribution of a standard model of industry dynamics. The method can be adapted to other, possibly non-monotone, regenerative processes found in industrial organization and other fields of economics. The algorithm we propose is a version of coupling from the past. It is straightforward to implement and exploit the regenerative property of the process in order to achieve rapid coupling.     

回收产品再生物流信息系统的集成模型

随着社会化大生产的发展,生产领域、流通领域和消费领域每时每刻都会产生大量的废旧物资。如何更好地对废旧物资进行回收、处理和再利用,是当前值得研究的重要课题。然后,再生物流的出现和发展必然要求有相应的信息系统提供支持。文中对再生物流信息集成平台进行了详细分析,探讨了平台的概念模型和功能模型,并基于Web技术和B/S网络模式,分析了信息集成平台的支撑体系结构。

高效氧化铝除氟剂及其除氟实用技术的研究

研究了选用经过特殊工艺处理的活性氧化铝作为高氟原水的除氟剂。在除氟剂对氟含量为10mg／L的原水处理试验中，当流速在80ml／min以下时，其终端流出水中的氟含量小于lmg／L；除氟剂的绝对饱和吸附量和相对饱和吸附量分别为1．67mg／g和1．57mg／g，再生活化后可恢复良好的除氟性能。研究结果显示活性氧化铝具有很好的实用前景。     

Knowledge of three regeneration programs and application behavior among Mississippi nonindustrial private forest landowners: A two-step sample selection approach

Various public financial assistance programs are available to nonindustrial private forest (NIPF) landowners in the United States. Many landowners have limited knowledge of these programs and have not utilized them. This study employed a two-step sample selection model to examine the determinants of NIPF landowner knowledge of three regeneration programs, and conditional on their knowledge, the determinants of the application frequency to these programs since 1996. Data were collected using a phone survey of NIPF landowners in Mississippi. The survey revealed that among these qualified landowners who had clearcut in the past 10 years, about 50% knew of one or more of the programs. Their application frequencies to individual programs ranged from 0 to 5. Landowner knowledge of the programs was positively related to land size, regeneration experience, gender, and membership in forestry associations. For landowners who knew of these programs, application frequencies were higher for those that had less acreage, had lower education or income, were fully employed, were female, or had no membership in forestry organizations.     

Assessment of brownfield redevelopment opportunities using a multi-tiered approach: A case in Italy

The objectives and implementation of environmental remediation and regeneration of brownfield sites have evolved over the years. Today, the intertwining of environmental, economic, and social issues related to the reuse of these sites is more apparent than in previous years; thus, the interconnectedness of these issues is now more considered in the remediation and regeneration of brownfield sites. The implications of environmental remediation and regeneration activities have broadened, leading to different and often contrasting interests among the stakeholders involved in these activities. In this study, we analyzed the role of private and public stakeholders in the remediation and regeneration of a brownfield site in Porto Marghera, Italy (Venice). We also examined the influence of the brownfield's site-specific features on its own remediation and regeneration. By adopting a multi-tiered approach, including, first, a desktop analysis and, second, in-depth interviews and a multi-criteria decision analysis, we identified factors that, if present or improved, could enhance the attractiveness of the area to developers and foster the site's redevelopment.     

空间-时间-度:城市更新的基本问题研究

城市更新首先需要判断哪里要更新、什么时候要更新、更新到什么程度合适;更新对象的空间、时间以及度的问题是城市更新必须回答的首要的基本理论问题.文章探讨了城市更新与空间、时间、度相对应的基本问题并做出了回答.     

地方理论:城市空间发展的再生理论

地方理论(Sense of Place)在城市与景观空间规划与发展领域中,代表着对环境研究的一种新角度和新方法,代表着当代城市与景观规划与设计研究的新视野。地方理论强调人与环境之间的感知、认知和记忆关联,是一种空间的再生产策略和方法。本文以地方理论为本体,探讨地方理论的本质内涵、构成体系及解构城市空间再生的方法论维度,如地方实践模式、地方再现模式、再现地方模式以及地方理论在城市规划与设计中的区位活化观、设计活化观、遗产活化观、形态活化观、产业活化观等再生设计策略,从而丰富和完善地方理论体系及城市规划与景观规划设计理论体系。
