Intelligent Agents for Disaster Management

ALADDIN [1] is a multi-disciplinary project that is developing novel techniques, architectures, and mechanisms for multi-agent systems in uncertain and dynamic environments. The application focus of the project is disaster management. Research within a number of themes is being pursued and this is considering different aspects of the interaction between autonomous agents and the decentralised system architectures that support those interactions. The aim of the research is to contribute to building more robust multi-agent systems for future applications in disaster management and other similar domains

Regional resilience in recessionary times: a case study of the East Midlands

Purpose: Since the 1990's the fashion industry has reflected the issues generally arising in the manufacturing sector, namely rapid and deep structural changes, the development of new supply chain relationships, ICT impacts and increasing globalisation with the attendant issues of ethical sourcing, off-shoring, new emerging markets and recessionary ripples. This paper focuses on one particular aspect of the fashion industry, namely the apparel sector and in particular 'fast fashion' to explore the issues arising for the SMEs in the supply chain. Approach: The research adopts a qualitative methodology and is longitudinal in nature, spanning 5 years from August 2006. The first stage of the research is reported here, where a series of focussed interview scenarios were conducted over an eighteenth month period. The sample of 12 SMEs was a convenience one, drawn from the 30 participants who took part in a business to business event in Leicester, a geographical location which acts as a microcosm of the apparel industry. Interviews were used to elicit narrative data about was what was actually happening in these apparel supply chains. Findings: The apparel supply chain has changed significantly due to recessionary ripples and structural changes. The SMEs have had more success in managing the upstream rather than the downstream relationships and relationships between buyer and suppliers continue to be fractious. Innovation has occurred but is hampered by the relationships that persist. Culture has proved to be a key dimension

Is agile project management applicable to construction?

This paper briefly summarises the evolution of Agile Project Management (APM) and differentiates it from lean and agile production and ‘leagile’ construction. The significant benefits being realized through employment of APM within the information systems industry are stated. The characteristics of APM are explored, including: philosophy, organizational attitudes and practices, planning, execution and control and learning. Finally, APM is subjectively assessed as to its potential contribution to the pre-design, design and construction phases. In conclusion, it is assessed that APM offers considerable potential for application in predesign and design but that there are significant hurdles to its adoption in the actual construction phase. Should these be overcome, APM offers benefits well beyond any individual project

Measuring time preferences

We review research that measures time preferences—i.e., preferences over intertemporal tradeoffs. We distinguish between studies using financial flows, which we call “money earlier or later” (MEL) decisions and studies that use time-dated consumption/effort. Under different structural models, we show how to translate what MEL experiments directly measure (required rates of return for financial flows) into a discount function over utils. We summarize empirical regularities found in MEL studies and the predictive power of those studies. We explain why MEL choices are driven in part by some factors that are distinct from underlying time preferences.National Institutes of Health (NIA R01AG021650 and P01AG005842) and the Pershing Square Fund for Research in the Foundations of Human Behavior

Conserving socio-ecological landscapes: An analysis of traditional and responsive management practices for floodplain meadows in England

Contemporary practice in the conservation of socio-ecological landscapes draws on both a model of responsive management, and also on ideas about historic management. This study considered what evidence might exist for the exercise of these approaches to management in the conservation of floodplain meadows in England, in order to inform understanding and knowledge of conservation management and assessment practice. Evidence for a model of responsive management was limited, with managing stakeholders often alternating between this model and an alternative approach, called here the ‘traditional management approach’, based on ideas, narratives and prescriptions of long-established land management practices. Limited monitoring and assessment appeared to undermine the former model, whilst uncertainty over past long-standing management practices undermined the latter. As a result of the relative power of conservation actors over farmers delivering site management, and their framings of meadows as ‘natural’ spaces, management tended to oscillate between aspects of these two approaches in a sometimes inconsistent manner. Conservation managers should consider the past motivating drivers and management practices that created the landscapes they wish to conserve, and bear in mind that these are necessarily implicated in aspects of the contemporary landscape value that they wish to maintain. They should ensure that assessment activity captures a broad range of indicators of site value and condition, not only biological composition, and also record data on site management operations in order to ensure management effectiveness

The Rule of Law as a Law of Standards: Interpreting the Internal Revenue Code

This Essay seeks to demonstrate that the interpretive use of standards in applying provisions of the Internal Revenue Code is not inconsistent with the rule of law. Part I discusses the relationship between rules and the rule of law and explains why we think so many tax scholars are drawn to a view of the tax law as consisting primarily of rules. We then demonstrate that the definition of income is properly understood as a standard. Part II addresses the descriptive dimension of this claim, summarizing and expanding our previous discussion of the definition of income to determine whether the term is susceptible to construction as a rule. We show that even a brief trip through some of the litigation required to determine whether certain items are income leads to the conclusion that the definition of income is not a rule. Part III addresses the normative dimension of our claim. There, we tease out the functions served by interpreting income as a standard and question where the interpretive authority lies with respect to the Code in order to argue that income ought to be treated as a standard. Part IV turns to several examples of what Professor Lawrence Zelenak regards as either a “disregard” or an “underenforcement” of the law to clarify our understanding of interpretation. We then conclude by observing that the Code does not “read itself”: Deciding whether a provision is itself a rule or a standard is itself an act of interpretation. Moreover, interpreting a provision as a standard is fully consistent with the rule of law

Clinical review: Biomarkers of acute kidney injury: where are we now?

The recognition that acute kidney injury (AKI) is a significant independent risk factor for morbidity and mortality has resulted in a substantial number of publications over the past 5 years or more. In no small part these have, to a degree, highlighted the inadequacy of conventional markers of renal insufficiency in the acute setting. Much effort has been invested in the identification of early, specific AKI markers in order to aid early diagnosis of AKI and hopefully improve outcome. The search for a 'biomarker' of AKI has seen early promise replaced by a degree of pessimism due to the lack of a clear candidate molecule and variability of results. We outline the major studies described to date as well as discuss potential reasons for the discrepancies observed and suggest that evolution of the field may result in success with ultimately an improvement in patient outcomes

Organizational Capital: A New Approach to Lending in Nonprofit Affordable Housing

In spite of a diminishing supply of public resources, many nonprofit housing developers are expanding their roles and their portfolios to address an increasing need for decent affordable housing. But as nonprofit housing organizations mature, the traditional project-by-project funding system fails to support their broader development goals. This paper stresses the urgent need for equity, or "organizational capital," to help nonprofit housing organizations build their capacity and their impact. Unlike conventional financing, organizational capital is underwritten against a borrower's balance sheet, or its organizational ability to repay. Whereas project-based loans are tied to one particular project, organizational loans can be a source of liquidity whenever an organization needs it: on the front end of a deal, for general business operations or during periods of organizational expansion. Despite its many advantages, there is an extremely limited supply of organizational capital in nonprofit affordable housing. This research outlines the practical challenges to organizational investing and uncovers the underlying barriers that have prevented a nonprofit organizational capital market from emerging. These findings lead us to explore nonprofit housing organizations in a "closed system" of standardized reporting and rational decision-making. The study concludes that while a new nonprofit reporting system would greatly encourage organizational investing in housing, the private markets alone will not bring organizational lending to scale. The final sections of the paper discuss the public policy implications of a closed nonprofit capital system and highlight some innovative approaches taken by lenders to overcome the obstacles of organizational investing and advance a new model of lending in nonprofit affordable housing
