Rationality,foolishness, and adaptive intelligence

Technologies of model‐based rationality are the core technologies of strategic management, having largely replaced earlier technologies that placed greater reliance on traditional practice or on communication either with the stars or with the gods. The technologies used by organizations in their pursuit of intelligence can be imagined to change over time as a result of responding to the successes and failures associated with the technologies. Although technologies of rationality seem clearly to be effective instruments of exploitation in relatively simple situations and to derive their adaptive advantage from those capabilities, their ventures in more complex explorations seem often to lead to huge mistakes and thus unlikely to be sustained by adaptive processes. Whether their survival as instruments of exploratory novelty in complex situations is desirable is a difficult question to answer, but it seems likely that any such survival may require hitchhiking on their successes in simpler worlds. Survival may also be served by the heroism of fools and the blindness of true believers. Their imperviousness to feedback is both the despair of adaptive intelligence and, conceivably, its salvation.

Corroborating social media echelon in cancer research

Worldwide medical facilities differ, and for this reason, the causes of death can vary. Cancer is considered the second leading cause of death after heart disease worldwide, and the same causes of death are observed in the United States (US). Therefore, the purposes of this study are to explore worldwide research levels in the field of cancer and the social collaboration of researchers and institutions in this field. This article examines the structural patterns of international co-authors and co-institutions in science citation index papers in cancer research. The study uses measures from the social network analysis method, including degree centrality, betweenness centrality, eigenvector centrality, and effectiveness, to investigate the effects of social networks in the area of cancer research. Empirical analysis results identify the US is the most central country, followed by Germany, Italy, France, and China, in terms of co-authored networks in this research field. Institutional analysis results indicate that the University of Milan is at the top in terms of degree centrality. The Gustave Roussy Cancer Campus in France and German University of Düsseldorf occupy the second and fourth positions, respectively. The University of California in Los Angeles and Harvard University, both in the US, are at third and fifth positions, respectively.     

Design principles for long‐lived Internet agents

Prior research on intelligent Internet agents has failed to address the needs of long‐lived data‐collecting agents, focusing instead on short‐lived transaction agents. Transaction agents typically run for a few seconds and retrieve information for a single transaction. With the staggering growth of electronic commerce, researchers and practitioners will want to design long‐lived data‐collecting agents that intelligently search for, retrieve, interpret, categorize, and store vast amounts of related information each time that they run. Such agents can run over the course of days rather than seconds and can be used by practitioners for decision support applications or by researchers as part of an empirical research methodology. This paper proposes a framework for agent sophistication, and emphasizes a number of design concepts for long‐lived Internet agents, including intelligence, validation, concurrency, recovery, monitoring, and interactivity. These concepts are used in the development of an illustrative tool called Electronic Data Retrieval LexicaL Agent (eDRILL), an object‐oriented data‐collecting agent. eDRILL is designed using the Unified Modeling Language (UML) and is written in Java. It gathers research data from an online auction. © 2000 John Wiley & Sons, Ltd.     

Internal governance mechanisms and firm performance in China

Corporate governance issues arising from concentrated ownership structure in emerging economies have received growing attention. Adopting a principal–principal perspective, this paper employs structural equation modeling to evaluate the independent and interdependent effects of internal governance mechanisms in enhancing firms’ value in China. Based on a 3-year dataset covering 304 publicly listed companies over 2003–2005, our findings suggest that ownership concentration has the most significant governance effect and has impacted negatively on firm performance. Furthermore, the governance role of the board of directors and supervisory boards is found to have been hindered by ownership concentration, rendering them unable to improve firm performance at present.     

Towards a Conceptualization of Unethical Marketing Practices in Tourism: a Case‐Study of Australia's Inbound Chinese Travel Market

This paper has a twofold purpose: to identify the types and impacts of unethical practices in an international travel market and to offer a generic model to enhance our understanding of the causes and consequences of such practices. The Chinese outbound market is used as a case study. The choice of China is timely and appropriate, given that the country is forecast to be one of the world's major outbound markets by 2010 with over 100 million leaving mainland China (World Tourism Organization [WTO], 2006 World Tourism Organization. 2006, November 7. The Chinese outbound tourism market Retrieved March 19, 2007, from http://www.unwto.org/media/Releases/2006/november/chineseoutbound.htm [Google Scholar]). The research setting is the Chinese inbound tourism market to Australia where the Chinese market has grown substantially since Approved Destination Status (ADS) was granted in 1999. The implications of this research for European and North American tourism operators are significant, given the 2005 agreement between the European Commission and the Chinese authorities that allows group travel from China into Europe. Using the long‐interview technique with industry participants in Australia and China a conceptual framework of the environment in which unethical practices occur is provided. A model illustrating antecedents, impacts, and outcomes of unethical practices is offered. Key managerial findings include the unhealthy consolidation of channel power in the Chinese market and the influence of ethnic networks across borders. Several key issues requiring further research are highlighted.     

The environmental effect of trade liberalization: Evidence from China's manufacturing firms

While prior literature on trade liberalisation and the environment has mostly focused on the macroeconomic ramifications, this study explores at the firm level whether and how changes of trade barriers brought about by China's accession to the WTO may impact on its manufacturing firms’ environmental performance. Adopting a difference-in-differences (DID) methodology, we document the effects of tariff reductions on improving firm-level SO2 emission intensity, and the key corporate strategic decisions responsible for delivering the observed results, with robustness tests covering other major pollutants. In response to trade liberalisation, firms are found to increase labour resources for environmental protection and to improve their production processes to reduce emission intensity. This study contributes to the literature by investigating at the level of the operating firm how output and input tariff reductions may impact on environmental performance and uncovering for the first time the specific actions responsible for the results.     

Financializing Desalination: Rethinking the Returns of Big Infrastructure

Against the trend prevalent during the 1990s and 2000s, large‐scale infrastructural projects have made a comeback in the water sector. Although sometimes framed as part of a broader sustainable transition, the return of big infrastructure is a much more complicated story in which finance has played a crucial role. In the following article, we explore this encounter between finance and water infrastructure using the case of Britain's first experiment in desalination technologies, the Thames Water Desalination Plant (TWDP). On the surface, the plant appears to be a classic example of the successes of normative industrial ecology, in which sustainability challenges have been met with forward‐thinking green innovations. However, the TWDP is utterly dependent on a byzantine financial model, which has shaped Thames Water's investment strategy over the last decade. This article returns to the fundamental question of whether London ever needed a desalination plant in the first place. Deploying an urban political ecology approach, we demonstrate how the plant is simultaneously an iconic illustration of ecological modernization and a fragile example of an infrastructure‐heavy solution to the demands of financialization. Understanding the development of the TWDP requires a focus on the scalar interactions between flows of finance, waste, energy and water that are woven through the hydrosocial cycle of London.
