Decision Support for Air Warfare: Detection of Deceptive Threats

This article describes an empirical study of the effectiveness of a decision support system called TADMUS. TADMUS is an acronym for Tactical Decision-Making Under Stress. The TADMUS DSS was developed at the Space and Naval Warfare Systems Center in San Diego.The TADMUS HCI was designed to mitigate the limitations of human cognition in the following 3 areas: perception, attention, and memory. We expected that decision makers would be better able to recognize deceptive threats if they used a compensatory decision aid that mitigated the effects of their cognitive limitations.Our participants were 90 US Navy officers who were enrolled at the Surface Warfare Officer's School. The participants were formed into 15 teams of six to perform the experimental task. Each team performed a total of three 25-minute threat detection scenarios. Eight of the teams had the aid of the TADMUS DSS, and 7 teams used the current US Navy training system called TASWIT.Teams performed significantly better at detection of deceptive threats when using the TADMUS DSS. We concluded that the design approach was successful.     

Can consumers buy alternative foods at a big box supermarket?

ABSTRACT

While consumers in affluent countries are ever hungry for alternatives to the ‘Big-Food’ mainstream, critical scholars have raised serious questions about the meaning of ‘alternative’ food products. I explore scholarly critiques of alternative food, and argue against a binary approach that sees foods as either alternative or not alternative. Instead, I suggest the utility of taking a multifaceted, ‘family of issues’ approach that is both reflexive and materialist. The case of ethical meat is used to explore the myriad, often contradictory ideals contained within consumers’ search for alternatives to mainstream market options. Three cautionary lessons are put forward. First, the goal of producing myriad consumer alternatives is significantly hampered by the competing, and often contradictory demands of market forces. Second, the discourse of food alternatives uses a ‘win-win’ logic suggesting that consumer sacrifice or change is unnecessary; the challenge of reshaping, and even downgrading consumer expectations is a necessary, but tremendous challenge facing consumer projects for ecological and social change. Third, the search for eco-social alternatives cannot simply make consumers feel good about their purchases, but must address the material realities and limitations of niche markets, and the need for structural reform to the food system.     

Understanding Absorptive Capacity from a Network Perspective

The term absorptive capacity refers to the notion that firms may have differing capabilities to innovate and to recognise the value of new knowledge, assimilate it, and apply it to creating business value. Developing such capabilities often requires firms to become part of a value network. We therefore apply the notion of absorptive capacity to the level of both the firm, and the wider value network in that it is embedded. The purpose of this research is to understand how absorptive capacity process may be moderated by contingent factors so that a more complete picture of absorptive capacity development emerges from our research. We identify from the literature on learning, innovation, and networks several theoretical perspectives that may help researchers to understand how contingent factors may facilitate and/or inhibit the development of absorptive capacity capabilities. We offer a set of propositions that may guide research into learning and innovation in business networks, and we discuss the managerial implications of these propositions.     

Corporate Social Responsibility: An Empirical Investigation of U.S. Organizations

Organizations that believe they should “give something back” to the society have embraced the concept of corporate social responsibility (CSR). Although the theoretical underpinnings of CSR have been frequently debated, empirical studies often involve only limited aspects, implying that theory may not be congruent with actual practices and may impede understanding and further development of CSR. The authors investigate actual CSR practices related to five different stakeholder groups, develop an instrument to measure those CSR practices, and apply it to a survey of 401 U.S. organizations. Four different clusters of organizations emerge, depending on the CSR practice focus. The distinctive features of each cluster relate to organizational demographics, perceived influence of stakeholders, managers’ perceptions of the influence of CSR on performance, and organizational performance.     

Valuing the Potential Transformation of Banks into Financial Service Conglomerates: Evidence from the Citigroup Merger

The merger between Citicorp and Travelers Group on April 6, 1998 could have emitted two relevant signals for firms that provide financial services. The first signal is the endorsement by two prominent financial institutions that benefits from cross‐selling of bank services with insurance services, brokerage services, and other financial services can be realized. The second signal is that regulators will allow the combination of commercial banking with insurance underwriting and full‐service brokerage, paving a path for similar combinations in the future. We document a favorable share price response for commercial banks, insurance companies, and brokerage firms, which supports the argument that the merger sets a precedent for other combinations between banks and nonbank financial services that will facilitate cross‐selling and efficiencies.     

Measuring firms’ imitation activity

Although imitation is more abundant and prevalent than innovation in firms’ product and process development activities, it has been understudied in research on innovation and R&D management. For example, a valid and reliable objective firm-level measure of the intensity of imitation activity is lacking in the extant literature. This measure is necessary to understand the antecedents and consequences of firms’ imitation activity, which has implications for R&D management. In this paper, we present novel methods that employ patent infringement litigations data to improve on the validity and reliability of measuring firms’ imitation activity. We validate our proposed measure by presenting a first model and test of R&D as a multiple-output production function with R&D expenditure as the primary input, and innovation and imitation as joint outputs. This is in contrast to current R&D models as a single-output production function of either innovation or imitation. This study uses a sample of 227 public firms from the computer, semiconductor, and pharmaceutical industries in the United States during 1991–2010.     

Women in public policy and public administration?

This paper explores the persistence of gender inequality in public administration in the UK and globally. The implications for the continued under-representation of women are explored. The data reveals vertical and horizontal occupational gender segregation which the paper argues, drawing upon representative bureaucracy research, has policy outcomes for beneficiaries of public services.     

Loss Given Default,Loan Seasoning and Financial Fragility: Evidence from Commercial Real Estate Loans at Failed Banks

Commercial real estate (CRE) loan losses are a recurring contributor to bank failures and financial instability, yet they are not well understood. We examine a unique and proprietary data set of CRE loan defaults at banks that failed and were resolved by the FDIC after the 2008 financial crisis. We build upon an existing literature relating stochastic collateral values to loss given default (LGD). Consistent with model predictions, we show that CRE loans defaulting sooner after origination are more sensitive to declining economic conditions and exhibit LGDs that are more severe. These results are robust to a number of factors, including the declining balance of the loan over time. Our findings point to an inherent fragility associated with high CRE loan growth, even without necessarily a deterioration in lending standards, due to the changing composition of CRE loan seasoning in the industry. This reflects an unexplored risk in the literature concerning rapid and cyclical expansions in CRE credit.

     

A Protestant Rethinking of Economics for a Healthier World

Neoclassical economic theory delivered upon its promise. It showed how the liberation of markets from government constraints could bring about a rapid expansion in the production of consumer goods. That was a major accomplishment. However, it came with a price in terms of social fragmentation, economic inequality, and a planetary ecosystem that is now overwhelmed by human activity. Continuing to follow the course plotted by conventional economics is a path to disaster. The world needs alternatives. Marxism has been tried and found wanting in many respects, including its abysmal environmental record. This article offers help from an unlikely source: insights of Reformed Protestantism that can be traced back to John Calvin in the 16^th century. Although Calvin and Calvinism are better known for a harsh view of human sinfulness, Calvin also contributed to the development of liberal democracies by advocating representative government, universal education, and greater participation by more people. Reformed theology emphasizes the importance of widespread participation in decisions, including economic decisions, at every level of society, and provides a positive role for institutions, including government, to protect the common good. It also points toward the need to situate economic policy in the larger domains of social and ecological health. Above all, it denies the validity of any economic system that deifies economics as such, and provides criteria for judging the effectiveness of economic systems as well as the evils of externalizing social and environmental costs in the name of a false efficiency.
