Integrated supply,production and distribution scheduling under disruption risks

This paper presents a bi-objective stochastic mixed integer programming approach for a joint selection of suppliers and scheduling of production and distribution in a multi-echelon supply chain subject to local and regional disruption risks. Two conflicting problem objectives are minimization of cost and maximization of service level. The three shipping methods are considered for distribution of products: batch shipping with a single shipment of different customer orders, batch shipping with multiple shipments of different customer orders and individual shipping of each customer order immediately after its completion. The stochastic combinatorial optimization problem is formulated as a time-indexed mixed integer program with the weighted-sum aggregation of the two objective functions. The supply portfolio is determined by binary selection and fractional allocation variables while time-indexed assignment variables determine the production and distribution schedules. The problem formulation incorporates supply–production, production–distribution and supply–distribution coordinating constraints to efficiently coordinate supply, production and distribution schedules. Numerical examples modelled after an electronics supply chain and computational results are presented and some managerial insights are reported. The findings indicate that for all shipping methods, the service-oriented supply portfolio is more diversified than the cost-oriented portfolio and the more cost-oriented decision-making, the more delayed the expected supply, production and distribution schedules.     

“全面科技哲学”取代“自然科技哲学”是新时代的呼唤--陈文化教授学术访谈录

目前现存的科技哲学更多地只是其中的一个门类———自然科技哲学，马克思的“全面发展”理论是“全面科技哲学”取代“自然科技哲学”的理论基础。全面科学技术哲学的研究对象、学科实质、门类构成和研究内容等方面，与传统的自然科技哲学均有较大的区别。根据马克思的“全面发展”理论，科技观可概括为三个方面，即横向活动中的自然科技、人文科技、社会科技“三者同时存在”与同时变化；纵向过程中的“全面科学、技术、技术创新、生产生活、社会变革和人的发展”由“人通过人的劳动”形成一个反馈圆环，以及科学整体发展的“动—静—动”的无限序列，也由此而提出“全面科技哲学纵横向发展平台”。自然科技哲学是工业社会的产物，而“全面科技哲学”是新世纪、新时代的必然要求。“全面科技哲学”取代自然科技哲学对形成具有中国特色与中国风格的科技哲学亦将起到推波助澜的作用。     

行政文化与国家治理能力的提升

行政文化是支配和制约行政行为的行政意识的综合体系。行政文化是影响行政绩效进而影响国家治理能力的重要因素。根据行政权威、行政理念、行政价值和行政规则四个维度及其强度的不同组合，形成了不同的行政文化模式。行政文化从总体上可分为整合型行政文化和离散型行政文化。协同性整合是整合型行政文化的最高境界。要提升国家治理能力必须优化行政文化，实现行政文化的协同性整合。行为学习、理念学习、价值学习和规则学习，从服从到顺应，再到认同和内化的学习过程，是实现行政文化协同性整合的内在机制，也是提升国家治理能力的根本途径。     

Imagined communities, contested watersheds: Challenges to integrated water resources management in agricultural areas

Integrated water resources management is one of the major bottom-up alternatives that emerged during the 1980s in North America as part of the trend towards more holistic and participatory styles of environmental governance. It aims to protect surface and groundwater resources by focusing on the integrated and collaborative management of land and water resources and interests on a watershed basis. In this paper, we draw on the policy network perspective on governance to shed light on the strengths and weaknesses of watershed-based processes of collaboration and integration for water quality protection in agricultural areas. The policy network perspective focuses on the interaction of actors, institutions and ideas within and among policy sectors to capture the intricacies of the policy process in increasingly complex and fragmented societies. Empirically, this study is based on the analysis of agro-environmental strategies for water quality protection in the Province of Ontario over the last 15 years. The contamination of a rural municipal well in Ontario in 2000, with its tragic consequences, translated into an ongoing pluralistic debate and strong attempts to fundamentally change the provincial policy style for addressing drinking water threats, especially agricultural pollution. Based on our analysis, we suggest that meaningful scales for collaboration and integration of land and water resources and interests at the local level, from the point of view of Ontario's agricultural policy network, do not currently include the watershed. We conclude that, instead of forcing watershed-based governance structures, the exploration and examination of more creative and flexible ways of linking watershed imperatives to existing socially and politically meaningful scales in agricultural areas of Ontario and elsewhere is warranted.     

An Integrated Human Behavior Theory

Abstract

In this article, the behavioral exchange model as derived from the work of Emerson, is presented to help the practitioner more adequately conceptualize the interaction between the clinician and the client. This model can help the clinician develop and further his/her understanding of how power differentials between the clinician and the client affect the therapeutic relationship. This model describes how clients use a cost-benefit framework to determine if treatment is worthwhile-meaning that if the client perceives the rewards of an interaction as not outweighing the costs, then the client may terminate treatment. Finally, this model can assist the clinician in constructing an integrative framework for the diverse variables reviewed in the text, and with this framework will be better equipped to influence them.     

Cross-sectoral collaboration working with perinatal women who use substances: outcomes and lessons from HerWay Home

ABSTRACT

HerWay Home is a multi-service drop-in and outreach program women for with substance use issues and who also may be affected by mental illness, trauma, and/or violence. Philosophical foundations of the program include harm reduction and being relationship-based and trauma-informed. This article presents the program’s evaluation findings related to cross-sectoral service collaborations and outcomes for service partners as well as for women and families, including prevention of children going into care. For service partners, HerWay Home provided peace of mind, knowing that vulnerable women’s needs would be met and also led to increased understanding about substance-using women and best practice approaches.

Endogenous Adaptation: The Effects of Technology Position and Planning Mode on IT‐Enabled Change*

The redesign of information technology (IT)‐enabled work processes often necessitates fundamental design changes to the intended work process, the IT platform hosting the work process, or both. Research suggests that such design changes often can be traced to earlier decisions involving endogenous adaptation or internal organizational change. Two such decisions are a firm's technology position and planning mode. This study examines the relationship between technology position and planning mode in predicting the magnitude of design change in process redesign projects. The conceptual frame applied in examining these relationships involves a synthesis of Miles and Snow's adaptive cycle with elements central to concurrent engineering. Our results indicate that the magnitude of design change is related to differences in technology position and planning mode. To effectively implement organizational change, firms must leverage their IT platform by carefully timing IT investments in accordance with their adopted technology position. Directing the trajectory of a firm's IT platform and deploying it so as to complement the firm's technology position reduces design uncertainty, promoting reengineering success.
