A comparison of the National Geographic Stewardship Scorecard Ratings by experts and stakeholders for selected World Heritage destinations

The National Geographic Society Center for Sustainable Destinations Stewardship Scorecards for 2003 and 2006 compared ratings by “experts” for 33 World Heritage Site destinations. Nine (27.3%) improved by four or more points and six (18.2%) decreased by four or more points in the three years. In 2006, local stakeholders rated these World Heritage destinations using the same criteria as the experts. Stakeholders rated six destinations (18.2%) lower and almost half of the 33 destinations (48.8%) increased by five or more points. A moderate positive correlation was determined between the ratings of the experts and stakeholders. Comments by experts and stakeholders related to each of the scorecard criterion measures were analyzed. ANOVA and t-test were performed to examine the six stakeholder categories ratings for each of the six criteria and the results are presented. The assumptions and limitations of the survey methodology are discussed along with recommendations for improving the Destination Stewardship Scorecard Survey.

Communication in financial markets with several informed traders

This paper investigates the incentives for informed traders in financial markets to reveal their information truthfully to the public. In the model, a subset of traders receive noisy signals about the value of a risky asset. The signals are composed of a directional component (“high” vs. “low”) as well as a precision component that represents the quality of the directional component. Between trading periods, the informed agents make public announcements to the uninformed traders. With a sufficiently large number of informed traders, an equilibrium exists in which the directional components are credibly revealed, but not the precision components. Even though the informed traders retain some of their rivate information, the post-communication estimate of the asset value converges in probability to the full-information estimate as the number of informed traders increases. The paper is based on a chapter of my Ph.D. thesis at the University of Western Ontario and was circulated previously under the title “Public Communication Devices in Financial Markets.” I thank my dissertation committee Arthur Robson, Hari Govindan, and Al Slivinski for their guidance and support. I also thank Murali Agastya, Roland Benabou, Philippe Grégoire, Rick Harbaugh, Mike Peters, an anonymous referee and an associate editor, and seminar participants at various universities and conferences at which this paper was presented.     

Locating a Space for Ethics to Appear in Decision-making: Privacy as an Exemplar

Using concepts from Ulrich Beck’s Risk Society, this paper argues that as expertise proliferates questions of ethics in decision-making fall through gaps between domains of expertise. As a consequence, unethical outcomes are unattached to actions taken with no one accountable or responsible for these outcomes. Using Actor-Network Theory (ANT), a case study is presented showing how the sale of students’ personal information by the Calgary Board of Education (CBE) escaped questions of ethics. The sale of student information was the product of the convergence of narrowly focussed technology and education expert actions and decisions with an earlier two-stage translation of privacy from a potential ethical issue to an issue of expert rule creation and interpretation. The purpose of this paper is to show, through an example, how questions of ethics are displaced in expert decision-making and to enable the public, managers, individuals and experts to recognize displacements and, through this, create a space for ethics to appear. Bill has conducted extensive research in the area of information technology and privacy, with a particular emphasis on how privacy issues play out in practice. The variety and complexity of interacting influences that shape privacy in practice has lead Bill to expand the scope of his research to include history, ethics and public plicy.

The differences in perception of radiological risks: lay people versus new and experienced employees in the nuclear sector

This paper studies the differences in perception of two radiological risks – an accident at a nuclear installation and medical X-rays – between four different groups: the general population without (1) and with experience related to radiological risks (2), new employees (3) and professionally exposed people (4) in the nuclear sector. More precisely, this study determines if differences in risk perception can be explained by the level of experiences with ionizing radiation, the knowledge level about radiological risks, the confidence in authorities, the attitude towards nuclear energy, the trust in a management of nuclear installations, gender and age. The data are gathered using computer assisted personal interviews based on the SCK-CEN Barometer of the Belgian Nuclear Research Centre. The relations between risk perception and the independent variables are tested with linear regression analysis. The risk perception of both risks differs significantly between the four population groups. The professionally exposed people and the new employees in the nuclear sector have a significant higher risk perception for medical X-rays compared to the risk for an accident at a nuclear installation. For the general population without experience, it was just the opposite. The general population with experience does not have a significant difference in risk perception between the two radiological risks. Level of experiences with ionizing radiation is determined as an important variable; people have a lower perception of radiological risks when they have higher experiences with risk.
