Decisions,Science, and Values: Crafting Regulatory Alternatives Analysis

Emerging “prevention‐based” approaches to chemical regulation seek to minimize the use of toxic chemicals by mandating or directly incentivizing the adoption of viable safer alternative chemicals or processes. California and Maine are beginning to implement such programs, requiring manufacturers of consumer products containing certain chemicals of concern to identify and evaluate potential safer alternatives. In the European Union, the REACH program imposes similar obligations on manufacturers of certain substances of very high concern. Effective prevention‐based regulation requires regulatory alternatives analysis (RAA), a methodology for comparing and evaluating the regulated chemical or process and its alternatives across a range of relevant criteria. RAA has both public and private dimensions. To a significant degree, alternatives analysis is an aspect of product design; that is, the process by which private industry designs the goods it sells. Accordingly, an RAA method should reflect the attributes of well‐crafted product design tools used by businesses. But RAA adds health and environmental objectives to the mix of concerns taken into account by the product designer. Moreover, as part of a prevention‐based regulatory regime, it implicates important public values such as legitimacy, equity, public engagement, and accountability. Thus, an RAA should reflect both private standards and public values, and be evaluated against them. This article adopts that perspective, identifying an integrated set of design principles for RAA, and illustrating the application of those principles.     

Applying the Housing First approach to single-site permanent supportive housing

This study explored how the U.S. Departments of Housing and Urban Development-Veterans Affairs Supportive Housing (HUD-VASH) program applies Housing First principles in the context of ten single-site programs. Focus group discussions with 64 HUD-VASH staff and community partners explored how the programs were influenced by Housing First principles and specific strategies to implement these principles in a single-site setting. Focus group respondents described resourceful ways that the principles of Housing First were implemented in their programs specifically related to (1) housing choice and structure, (2) separation of housing and services, (3) service philosophy, and (4) service array. Several of the Housing First domains cite the importance of integrated housing and the provision of services off-site; it was of particular interest to learn how single-site programs address these issues logistically. Lessons learned from this study include the importance of leveraging the independent yet overlapping tasks of case management and property management to ensure functional – if not geographic – separation of housing and services; maintaining staff on-site to address Veterans’ needs; working with community service organizations to complement the array of service available to residents; and housing single-site programs in mixed-use buildings.     

长江经济带社会经济发展与水资源保护水平研究

随着我国“三大战略”的实施,长江经济带生态走廊建设引起了广泛关注。以长江经济带11省市社会经济发展、水环境、水生态为研究对象,运用DPSIR框架模型,从驱动力-压力-状态-影响-响应的相互作用机制出发,选取2005—2014年11省市26个相关指标,预测长江经济带水资源综合保护水平。结果显示：长江经济带中下游的水资源保护水平整体较高,而整个经济带水质、水量与水生态保护水平均面临较大压力。     

Assessing global leadership competencies: the critical role of assessment centre methodology

The purpose of this conceptual paper is to examine the use of assessment centre (AC) methodology for addressing the ever-increasing demand for effective talent management of global leaders. Research is reviewed on the most commonly used questionnaire tools for assessing global leadership competencies, which lack the AC’s ability to provide behavioural evidence of leadership competency. A literature search is conducted to identify the extent to which scholarly research to date has examined the use of ACs to measure global leadership competencies. Based on the findings from the review of the literature, the authors recommend further exploration of a leadership AC approach as a ‘best practice’ talent management tool for measuring global leadership competencies. A framework is provided for designing ACs to evaluate and provide developmental feedback on the competencies identified as critical for successful leadership performance in an organization’s global environment.     

The utility of situational theory of publics for assessing public response to a disaster prediction

The study of public response to disasters is a relatively recent discipline that developed following the passage of the Earthquake Hazards Reduction Act of 1977. Because earthquake prediction is an inexact science, few formal predictions have been issued, which has limited the opportunity to study public response to predictions. The purpose of this study was to examine the utility of public relations theory, specifically situational theory of publics, for assessing response to the New Madrid earthquake prediction.Situational theory demonstrates that there is not a single, general public for disaster predictions as has been assumed in studies of disaster response. Instead, multiple publics develop in response to a prediction based on how members of those publics view the situation. Contrary to previous findings that believability and personalized risk are correlated constructs, high personalized risk was associated with high constraint recognition regardless of belief in the prediction. Based on the findings, suggestions are proposed for the development of more effective messages for communicating with publics at risk.     

Learning How and Learning What: Effects of Tacit and Codified Knowledge on Performance Improvement Following Technology Adoption

This paper examines effects of tacit and codified knowledge on performance improvement as organizations gain experience with a new technology. We draw from knowledge management and learning curve research to predict improvement rate heterogeneity across organizations. We first note that the same technology can present opportunities for improvement along more than one dimension, such as efficiency and breadth of use. We compare improvement for two dimensions: one in which the acquisition of codified knowledge leads to improvement and another in which improvement requires tacit knowledge. We hypothesize that improvement rates across organizations will be more heterogeneous for dimensions of performance that rely on tacit knowledge than for those that rely on codified knowledge (H1), and that group membership stability predicts improvement rates for dimensions relying on tacit knowledge (H2). We further hypothesize that when performance relies on codified knowledge, later adopters should improve more quickly than earlier adopters (H3). All three hypotheses are supported in a study of 15 hospitals learning to use a new surgical technology. Implications for theory and practice are discussed.
