The Agrium Redwater Nitrogen Operations Ammonia 2 plant underwent a phased project to upgrade and modernize its automatic safety shutdown system. Agrium incorporated the use of safety integrity levels in the functional design and detailed design of the safety shutdown system to ensure that all required protections were implemented in a safe and cost-effective manner. This article discusses the methodology used to determine the scope of the system, the methodology used to define the functional design, the implementation strategy chosen and the key lessons learned from the execution of this project. © 2009 American Institute of Chemical Engineers Process Saf Prog 28:282–292, 2009 相似文献

Choice models in marketing and economics are generally derived without specifying the underlying cognitive process of decision making. This approach has been successfully used to predict choice behavior. However, it has not much to say about such aspects of decision making as deliberation, attention, conflict, and cognitive limitations and how these influence choices. In contrast, sequential sampling models developed in cognitive psychology explain observed choices based on assumptions about cognitive processes that return the observed choice as the terminal state. We illustrate three advantages of this perspective. First, making explicit assumptions about underlying cognitive processes results in measures of deliberation, attention, conflict, and cognitive limitation. Second, the mathematical representations of underlying cognitive processes imply well documented departures from Luce’s Choice Axiom such as the similarity, compromise, and attraction effects. Third, the process perspective predicts response time and thus allows for inference based on observed choices and response times. Finally, we briefly discuss the relationship between these cognitive models and rules for statistically optimal decisions in sequential designs. 相似文献

Applying a recent bootstrap autoregressive distributed lag method, this article re-examines the energy-growth relationship for 22 OECD countries over the period 1966–2013. The empirical results suggest degenerate cases for eight countries. Only Japan is truly cointegrated. Some causality patterns are identified. 相似文献

There are many aspects of the “economics of education” that would make excellent examples for introductory economics students. The author presents two topics that are central to the economics of education and to human capital theory: the economic benefit (or “returns”) to schooling and educational attainment as an investment. There are two key concepts the author hopes students get from this discussion. The first is that there are both private and social benefits of schooling whence we derive the rationale for government intervention. The second is that educational attainment is an investment decision with both costs and benefits, and some risk. 相似文献

The present study investigated the association between faculty publication records and their point-based evaluations of finance journals. No relationship was detected between the merit points assigned to finance journals and the journal-specific success of the faculty rendering the journal ratings. However, a negative relationship was found between general publication success of faculty and the merit points they assigned to lower-level journal publications. The association was particularly strong for faculty who had published in the top three finance journals. 相似文献

The value that many superpaid CEO superstars supposedly created has largely disappeared, and the likelihood that it will be recovered anytime soon seems remote. On top of that, a good number of top executives treated their companies like ATMs, awarding themselves millions of dollars in corporate perks. It's hard to dispute the idea that executives were corrupted by the sums of money dangled in front of them. What's wrong with executive compensation, and what can we do about it? HBR and the University of Delaware's Center for Corporate Governance convened a round-table of compensation experts last October on the university's campus in Newark, Delaware. The 12 panelists, from CEOs to investors, from the professionals who advise them to a chief justice who rules on their disputes, provided an extraordinary diversity of viewpoints. The panelist began by debating ways to align the interests of the senior executives with the long-term interests of the company-weighing the relative benefits of stock options versus stock grants, for instance. But the discussion expanded to cover broader questions of corporate governance and company values. "The main reason compensation increases every year is that most boards want their CEO to be in the top half of the CEO peer group," said Ed Woolard,Jr., a former CEO of DuPont. And compensation lawyer Joe Bachelder pointed out the danger of structuring pay in such a way that it dampens risk taking among executives. It was a lively and wide-ranging discussion of one business's most pressing issues. 相似文献
