An evaluation of multi‐criteria methods in integrated assessment of climate policy

Those who conduct integrated assessments (IAs) are aware of the need to explicitly consider multiple criteria and uncertainties when evaluating policies for preventing global warming. MCDM methods are potentially useful for understanding tradeoffs and evaluating risks associated with climate policy alternatives. A difficulty facing potential MCDM users is the wide range of different techniques that have been proposed, each with distinct advantages. Methods differ in terms of validity, ease of use, and appropriateness to the problem. Alternative methods also can yield strikingly different rankings of alternatives. A workshop was held in which climate change experts and policy makers evaluated the usefulness of MCDM for IA. Participants applied several methods in the context of a hypothetical greenhouse gas policy decision. Methods compared include value and utility functions, goal programming, ELECTRE, fuzzy sets, stochastic dominance, min max regret, and several weight selection methods. Ranges, rather than point estimates, were provided for some questions to incorporate imprecision regarding weights. Additionally, several visualization methods for both deterministic and uncertain cases were used and evaluated. Analysis of method results and participant feedback through questionnaires and discussion provide the basis for conclusions regarding the use of MCDM methods for climate change policy and IA analyses. Hypotheses are examined concerning predictive and convergent validity of methods, existence of splitting bias among experts, perceived ability of methods to aid decision‐making, and whether expressing imprecision can change ranking results. Because participants gained from viewing a problem from several perspectives and results from different methods often significantly differed, it appears worthwhile to apply several MCDM methods to increase user confidence and insight. The participants themselves recommended such multimethod approaches for policymaking. Yet they preferred the freedom of unaided decision‐making most of all, challenging the MCDM community to create transparent methods that permit maximum user control.

Special perspective: An immodest proposal: should treating mental health professionals be barred from testifying about their patients?

Notwithstanding ethical rules that address therapeutic and forensic role conflicts for psychologists and psychiatrists, overzealous patient advocacy by therapists, tightened reimbursement for therapy, and a growth market for forensic psychology and psychiatry, have led many therapists to appear willingly as forensic experts on behalf of their patients. Existing ethical rules, as well as other proposed approaches to address this problem, assume that it can be resolved by modest changes in existing practice that permit therapists to testify as long as their testimony avoids psycholegal opinions. This essay questions whether these modest changes can adequately address this problem and advances consideration of a more radical proposal to address this problem, prohibiting therapists from testifying about their patients. © 1998 John Wiley & Sons, Ltd.     

Fictions,feelings, and emotions

Many philosophers suggest (1) that our emotional engagement with fiction involves participation in a game of make-believe, and (2) that what distinguishes an emotional game from a dispassionate game is the fact that the former activity alone involves sensations of physiological and visceral disturbances caused by our participation in the game. In this paper I argue that philosophers who accept (1) should reject (2). I then illustrate how this conclusion illuminates various puzzles in aesthetics and the philosophy of mind.     

An Ecological Approach to Reducing the Social Isolation of People With an Intellectual Disability

An ecological approach to understanding insecure attachments and social isolation among people with an intellectual disability is constructed using Gibson's (1979/1986) affordance-based theory. Although environmental affordances and individual limitations interact to limit the development of social competence, we believe that by focusing on the immediate environment, community-based approaches to helping people with an intellectual disability are often ignored, which increases the burden on individual caregivers. A more comprehensive strategy, which extends Gibson's theory of affordances, allows us to consider how higher level social systems influence the immediate environment and provides the context for understanding why successful change occurs when a multifaceted, holistic approach that works on several levels is adopted. Examining these systems within an ecological framework fundamentally redefines our thinking by shifting the focus from a person's disability to a more nuanced understanding of a person's abilities within the context of appropriate environmental supports in which the person's disability becomes less salient.

Sufficient conditions for the discrimination of motion

When one half of a randomly contoured pattern is displaced in one of four directions between successive exposures, Ss are capable of discriminating the direction of the displacement. Accuracy of discriminating decreases as a function of the relative displacement within the pattern, independent of the visual angle subtended by the pattern. Supplementary data suggest that Ss are unrealistically confident in the accuracy of their discrimination. The results demonstrate that identification of specific contours is not necessary for the discrimination of motion and suggest that some type of correlational process is employed by the visual system in dealing with spatially and temporally displaced patterns.
