Antecedent-Relative Comparative World Similarity

In “Backward Causation and the Stalnaker–Lewis Approach to Counterfactuals,” Analysis 62:191–7, (2002), Michael Tooley argues that if a certain kind of backward causation is possible, then a Stalnaker–Lewis comparative world similarity account of the truth conditions of counterfactuals cannot be sound. In “Tooley on Backward Causation,” Analysis 63:157–62, (2003), Paul Noordhof argues that Tooley’s example can be reconciled with a Stalnaker–Lewis account of counterfactuals if the comparative world similarity relation on which the Stalnaker–Lewis account relies is allowed to be antecedent-relative. In this paper I show that taking comparative world similarity to be antecedent-relative results in a formal semantics which is a comparative world similarity semantics in name only.     

The Reliability and Validity of Big Five Inventory Scores With African American College Students

The reliability and validity of scores on the Big Five Inventory (BFI; O. P. John, E. M. Donahue, & R. L. Kentle, 1991) were examined in a sample of 336 African American college students. Results indicated moderate reliability and structural validity for BFI scores. Additionally, BFI subscales had few meaningful correlations with self‐esteem and social desirability. La fiabilidad y la validez de los resultados del Inventario “Big Five” (BFI; O. P. John, E. M. Donahue, y R. L. Kentle, 1991) se examinan en una muestra de 336 estudiantes universitarios afro‐americanos. Los resultados indican una fiabilidad moderada y una validez estructural para los resultados del BFI. Adicionalmente, las subescalas del BFI tuvieron pocas correlaciones importantes con el auto‐estima y el deseo social.     

Meta-analyses and systematic reviews of psychological treatments for chronic pain: relevance to an evidence-based practice.

As evidence-based practitioners become more reliant on systematic reviews to inform treatment, it becomes important to systematize reporting details as well as improve the quality of the primary studies that will later be incorporated into this secondary literature. In this article, the authors consider several specific factors that can serve this function in the area of chronic pain: (a) adhering to a standardized set of reporting standards; (b) measuring a standardized set of short- and long-term outcome variables; (c) providing information about individual differences; and (d) providing detailed, easily accessible documentation of the treatment program (or progams). The article also highlights ways that practitioners and researchers can collaborate on treatment outcome research, thereby improving the ability to discover and disseminate effective treatments for patients who suffer from chronic pain.     

LOTTERIES AND THE TIME HORIZON

Abstract— People chose between hypothetical alternatives of (a) a million-dollar lottery prize and (b) a much smaller but certain amount of money When probabilities of winning the lottery were above about 1/100,000, subjects avoided risk, for example, a 1/100,000 probability of the million-dollar prize was chosen about as often as $700 for sure But at probabilities below 1/100,000, subjects sought risk, for example, a 1/1,000,000 probability of the million-dollar prize was chosen about as often as $9 for sure This crossover from risk aversion to risk seeking is predicted by Mazur's (1987) hyperbolic delay discount function with probability expressed as average delay due to strings of losses followed by a win, together with a time horizon limiting subjective delay     

An empirical investigation of adolescent suicidal ideation.

Four hundred nine high school students were surveyed to determine the percentage who had experienced suicidal ideation. The sample was then divided into high- and low-suicidal-risk groups. High-risk subjects were found to have significantly poorer quality friendships, lower self-esteem, and had experienced more life stress in the previous year.     

Stimulus range,number of categories,and the “virtual” exponent

Three different stimulus modalities (line length, number, and sound pressure) were judged by magnitude scaling techniques and by 7-, 15-, 31-, and 75-point category scales. All of the 40 subjects were given the same number stimuli, but two different sound-pressure ranges were presented (each to 20 subjects) and four different line-length ranges were presented (each to 10 subjects). Analyses of lack of fit for various simple functions were performed to determine bestfitting functions. The simple power function was often found to be an adequate fit to the data for all the response modalities used, although all of the response modalities were sensitive to changes in stimulus range. For simple power functions, the category-scale exponent was a function of both the range of stimuli and the number of categories provided. Category scales did not always produce exponents smaller than those obtained with magnitude estimation, which calls into question the concept of a virtual exponent for category scales.     

Moralist,technician, sophist,teacher/learner: Reflections on the ethicist in the clinical setting

The ethicist's role in the clinical context is not presently well defined. Ethicists can be thought of as moralists, technicians, Sophists, or as teachers and learners. Each of these roles is examined in turn. An argument is made for the ethicist as a teacher who must also learn a great deal about the clinical setting in order to encourage an effective critical examination of basic values. Four specific tasks of this teaching role are discussed: describing moral experience, eliciting assumptions, considering multiple alternatives and justifying choices.
