Toxic hazard reduction with passive mitigation systems

A major component of the United States Environmental Protection Agency's 112(r) Risk Management Program Rule is the evaluation and control of potential public exposures to toxic chemicals. The rule requires identification and evaluation of a worst case accidental toxic release scenario, but provides for the inclusion of passive mitigation systems in modeling the dispersion hazard zones that are to be communicated to the public. These passive mitigation systems can be taken into account in the consequence modeling if they will withstand the initiating event that causes the accidental release and function as intended. This paper discusses several passive mitigation systems that can be designed as an integral part of storage or processing of highly toxic chemicals. These include, but are not limited to, optimizing storage conditions, design of secondary containment, toxic vapor generation control, and enclosure design. The effectiveness of various passive mitigation systems is evaluated using consequence modeling for case studies involving highly toxic chemicals such as phosgene, chlorine, and ethylene oxide.     

The Role of Moral Philosophies,Operational Criteria and Operational Strategies in Determining Equitable Allocation of Resources for Leisure Services in the United States

Abstract

This paper revises an earlier taxonomy of equity models that was published in this journal in 1988. This revised taxonomy consists of three elements. First, it extends the original taxonomy by proposing a set of moral philosophies, positioning them as antecedents of the operational strategies that determine equity outcomes. Six are identified: Rawlsian, egalitarianism, benefit principle, utilitarianism, libertarianism and paternal professionalism. It is suggested that communitarianism offers a philosophical basis for reconciling some of the antithetical perspectives embedded in these six moral philosophies. A second element in the taxonomy suggests the operational criterion flowing from each of the moral philosophies when it is adapted as the basis for policy decisions regarding the allocation of resources to leisure services. The third element identifies 14 operational strategies that determine equity outcomes. Their linkage to operational criteria and moral philosophies is shown. Potential equity consequences and implications of the operational strategies are illustrated and compared by use of a scenario relating the allocation of resources to park land acquisition.     

Inflation and growth: new evidence from a dynamic panel threshold analysis

We introduce a dynamic panel threshold model to estimate inflation thresholds for long-term economic growth. Advancing on Hansen (J Econom 93:345–368, 1999) and Caner and Hansen (Econom Theory 20:813–843, 2004), our model allows the estimation of threshold effects with panel data even in case of endogenous regressors. The empirical analysis is based on a large panel-dataset including 124 countries. For industrialized countries, our results confirm the inflation targets of about 2% set by many central banks. For non-industrialized countries, we estimate that inflation rates exceeding 17% are associated with lower economic growth. Below this threshold, however, the correlation remains insignificant.     

Gender,Distribution, and Balance of Payments Constrained Growth in Developing Countries

An unresolved debate in the development literature concerns the impact of gender equality on economic growth. Previous studies have found that the effect varies, depending on the measure of equality (wages or capabilities). This paper expands that discussion by considering both the short and long run, evaluating the effects of gender equality in two types of economies—semi-industrialized economies (SIEs) and low-income agricultural economies (LIAEs). Further, it incorporates gender effects on the balance of payments constraint to growth. The results suggest that gender wage and capabilities equality work in opposite directions in SIEs and in the same (positive) direction in LIAEs. In the long-run analysis, government macroeconomic management policies are shown to be necessary in order to ratify movements towards gender equality.     

Governing business process offshoring: Properties,processes, and preferred modes

This article examines an important yet understudied issue—the governance mode for business process offshoring (BPO). By applying transaction cost economics and organizational control perspective in the global BPO context, we suggest that BPO's governance mode (foreign captive, joint venture, and independent vendor) is determined by task features, such as knowledge specialization, information security, and process codifiability, and by needed process integration, horizontally between departments and units within the provider and vertically between the provider and its global client and its local subcontractor. Findings from our analysis of 308 global BPO units in India and China confirm our hypotheses.     

Are consumers' financial needs and values common across cultures? Evidence from six countries

Are consumers' financial needs, and financial values, the same or different across cultures? Two studies, with student (Study 1; n = 988) and non‐student (Study 2; n = 959) participants, explore the extent of equivalence, across six countries (Brazil, Russia, China, Taiwan, Tunisia and US), in financial need belief, and financial value, measurement models. The financial need beliefs, derived from self‐determination theory (SDT) principles, include financial self‐efficacy, financial autonomy, financial community trust and support; the financial values include materialism and financial altruism. Both the financial need and financial value constructs evidence configural invariance (similar factor structure), and factor invariance among student but not non‐student samples. The financial need constructs evidence full, and the financial value constructs evidence partial, metric (factor loading) invariance. Factor covariance invariance obtains for the financial need beliefs constructs but not the financial value constructs. Finally, neither financial need nor financial value constructs evidence scalar (intercept) invariance. These results provide partial support for extending SDT's hypothesis of universal human needs to the financial domain. In contrast, the financial value constructs of altruism and materialism are largely instable across cultures, suggesting that consumer views of giving, and the role of wealth in social status, differ between countries.     

Leaders and Laggards: The Influence of Competing Logics on Corporate Environmental Action

We study the sources of resistance to change among firms in the Canadian petroleum industry in response to a shift in societal level logics related to corporate environmental performance. Despite challenges to its legitimacy as a result of poor environmental performance, the Canadian petroleum industry was divided as to how to respond, with some members ignoring the concerns and resisting change (i.e., laggards) while others took action to ensure continued legitimacy (i.e., leaders). We examine why organizations within the same institutional field responded differently, delaying the industry response. We found that one population of firms was aligned with increasing pressures from its stakeholders for improved environmental performance, and the other was influenced by local cultural, political, and economic ideals less demanding of environmental actions. Our results reveal that several factors both at the institutional field level and the organizational level affected how these two populations reacted to a changing societal logic. Implications for theory, practice, and future research are discussed.     

The uncertainty challenge of contingent collaboration

Contingent knowledge workers will play an increasingly important role in organisational success as workers transition in and out of project‐based innovation teams with more frequency. Our research finds that collaborators in the contingent, high‐skill workforce face uncertainty challenges to their work that are unique from the independent, contingent professionals more often studied. The article proposes a theoretical framework of uncertainty to guide us in understanding collaborative contingent knowledge workers’ work experience. Interviews with postdoctoral researchers reveal four findings about the influence of these highly uncertain work environments on collaborative contingent knowledge workers – collaboration isolation, frustrated independence, performance anxiety and internalised blame. Perhaps most concerning is that the workers internalise the negative impacts as personal failings instead of recognising them as consequences of a poorly designed work environment. This study argues for the need to manage and mitigate different sources of uncertainty to avoid creating an unnecessary burden on contingent knowledge workers, and to enable a sustainable, contingent knowledge workforce.     

Product Ratings as a Market Reaction to Deregulation: Evidence From the German Insurance Market

This study provides the first investigation of information markets as a reaction to deregulation of product forms in insurance markets. The article studies the case of Germany, where insurance product ratings entered the market after relaxation of product regulation in 1994. The ratings’ potential for enhancing the performance of a deregulated insurance market is analyzed by considering both market structure and governance characteristics of the rating market, since the theoretical literature predicts that both are important determinants of rating outcomes. Data from a unique panel data set containing disability insurance ratings from the three major rating agencies are also examined in light of theoretical predictions. Results suggest that market governance and competition characteristics are favorable for the production of unbiased and informative ratings. Ratings for disability insurance support this interpretation, since the characteristics of the ratings conform to theoretical predictions about ratings in well‐functioning rating markets.
