The logic of ability,freedom and responsibility

The aim of this paper is to offer a rigorous explication of statements ascribing ability to agents and to develop the logic of such statements. A world is said to be feasible iff it is compatible with the actual past-and-present. W is a P-world iff W is feasible and P is true in W (where P is a proposition). P is a sufficient condition for Q iff every P world is a Q world. P is a necessary condition for Q iff Q is a sufficient condition forP. Each individual property S is shown to generate a rule for an agent X. X heeds S iff X makes all his future choices in accordance with S. (Note that X may heed S and yet fail to have it). S is a P-strategy for X iff X's heeding S together with P is a necessary and sufficient condition for X to have S. (P-strategies are thus rules which X is able to implement on the proviso P).Provisional opportunity: X has the opportunity to A provided P iff there is an S such that S is a P-strategy for X and X's implementing S is a sufficient condition for X's doing A. P is etiologically complete iff for every event E which P reports P also reports an etiological ancestry of E, and P is true. Categorical opportunity: X has the opportunity to A iff there is a P such that P is etiologically complete and X has the opportunity to A provided P. For X to have the ability to A there must not only be an appropriate strategy, but X must have a command of that strategy. X steadfastly intends A iff X intends A at every future moment at which his doing A is not yet inevitable. X has a command of S w.r.t. A and P iff X's steadfastly intending A together with P is a sufficient condition for X to implement S. Provisional ability: X can A provided P iff there is an S such that S is a P-strategy for X, X's implementing S is a sufficient condition for X's doing A, and X has a command of S w.r.t. A and P. Categorical ability: X can A iff there is a P such that P is etiologically complete and X can A provided P. X is free w.r.t. to A iff X can A and X can non- A. X is free iff there is an A such that X is free w.r.t. A.     

Immigrant skill utilization in the Canadian labour market: Implications of human capital research

The quantitative significance of the underutilization of immigrant skills may be assessed, albeit imprecisely, in human-capital earnings analysis. Earnings deficits of immigrants may arise from: (a) lower immigrant skill quality, (b) underutilization of immigrant skills, and (c) pay inequities for immigrants doing the same work as native-born Canadians. Consistent with numerous studies, data from the 1996 census micro-data show that underutilization of immigrant skills is significant, though less so than unequal pay within occupations. In 1996 dollars, the total annual immigrant earnings deficit from all three sources was 15.0 billion, of which15.0 billion, of which 2.4 billion was related to skill underutilization, and 12.6 billion was related to pay inequity. Discussion considers adjustments to these estimates, taking account of difficulties measuring the skill levels of occupations and immigrant skill quality. < /div > < div class=Äbstract» < a name=Äbs2» < /a > La signification quantitative de la sous-utilisation des qualifications immigrées peut être évaluée, quoique sans précision, dans l￠analyse humain-capitale de revenus.

Maximum likelihood estimation of the joint covariance matrix for sections of tests given to distinct samples with application to test equating

Consider an old testX consisting ofs sections and two new testsY andZ similar toX consisting ofp andq sections respectively. All subjects are given testX plus two variable sections from either testY orZ. Different pairings of variable sections are given to each subsample of subjects. We present a method of estimating the covariance matrix of the combined test (X ₁, ...,X _s ,Y ₁, ...,Y _p ,Z ₁, ...,Z _q ) and describe an application of these estimation techniques to linear, observed-score, test equating.The author is indebted to Paul W. Holland and Donald B. Rubin for their encouragement and many helpful comments and suggestions that contributed significantly to the development of this paper.This research was supported by the Program Statistics Research Project of the ETS Research Statistics Group.     

Development and Evaluation of a Decision Aid About Prenatal Testing for Women of Advanced Maternal Age

Objective: To develop and evaluate a decision aid designed to prepare patients of advanced maternal age for counseling about prenatal diagnostic testing. Setting: A regional genetics center. Design: A before/after study. Interventions: Participants used an audioguided workbook to learn about options and outcomes and to clarify personal risks, values, questions, and predispositions. Subjects: 21 women of advanced maternal age and 17 spouses. Main outcome measures: Knowledge of prenatal testing alternatives, decisional conflict, level of anxiety, and acceptability of the decision aid. Results: After using the decision aid, participants had significantly reduced decisional conflict (uncertainty) and a significant increase in knowledge. There was no effect on state or trait anxiety. More than three-quarters of participants were satisfied with the length, clarity, balance, and acceptability of the decision aid. Conclusions: The decision aid shows promise as a useful aid for preparing couples for counseling.     

Knowledge despite falsehood

I examine the claim, made by some authors, that we sometimes acquire knowledge from falsehood. I focus on two representative cases in which a subject S infers a proposition q from a false proposition p. If S knows that q, I argue, S's false belief that p is not essential to S's cognition. S's knowledge is instead due to S's belief that p′, a proposition in the neighbourhood of p that S (dispositionally) believes (and knows). S thus knows despite her false belief. The widely accepted and plausible principle that inferential knowledge requires known premises is unscathed.     

One Aspect of Hartmann's Review of Human Nature and Enduring Peace

Summary

Eighty Negro boys and girls, ages 3 to 5, were assigned to one of eight conditions. Race of model (Negro vs. white), type of consequence to model (reward vs. punishment), and percent of rewarded or punished responses (20 vs. 80 percent) were varied. The Ss viewed a television tape of a model (M) performing a simple two-choice discrimination task with either verbal reward or verbal punishment administered. After watching M make his choice, the S then made his own choice. When S's choice was the same as M's, imitative behavior was said to have occurred. There were significant effects of both race of M and type of consequence to M. Negro S imitated the white M more than the Negro M and imitated the rewarded M more than the punished M. The punished white M was imitated at approximately the same level as the rewarded Negro M. No significant effects of percent of reinforcement were found. Possible explanations of the experimental results were discussed.     

Some general laws of human emotion: Interrelationships between intensities of desire, expectation, and emotional feeling

Two experiments were performed to determine how desires and expectations interact to influence the intensities of emotional feelings. The first experiment required participants to respond to their imagined intensities of desire and expectation in two hypothetical situations, (1) anticipating different probabilities of receiving money (2) anticipating the possibility of different durations of continuous rain combined with different probabilities of rain occurring. Participants responded by producing line lengths to desire and feeling, a form of cross-modality matching. Feeling intensity but not desire intensity increased as a negatively accelerating power function of expectation for the positive approach goal of receiving money (F =KE^0.5) and both desire and feeling were negatively accelerating power functions of the hypothetical amount of money presented (F=K$⁴; D=K$⁴). Feeling intensity but not desire intensity increased as a positively accelerating function of expectation for the negative avoidance goal of anticipating different amounts of rain (F=KE^1.9) and both desire and feeling were negatively accelerating functions of amount of rain (F=KR^0.9; D=KR_0.9). The second experiment required participants to make visual analogue scale responses to desire, expectation, and emotional feeling intensities in ordinary life situations. Similar to Experiment 1, feeling intensity but not desire intensity increased as a negatively accelerating function of expectation for positive approach goals (F=KE^0.6) and as a positively accelerating function of expectation for negative avoidance goals (F=KE^2.0). Functional interrelationships found in both experiments were fit to the general equations F=K₁D+K₂DE^0.5 for positive approach goals and F=K₁D+K₂DE^2.0 for negative avoidance goals. Both equations have the same general form and indicate that desire and expectation have a multiplicative interaction with respect to their influence on emotional feeling intensity. Both functions     

Kant,the Third Antinomy and Transcendental Arguments

In this paper, I consider whether a reading of Kant's solution to the Third Antinomy can offer material for devising a new model of transcendental argument. The problem that this form of argument is meant to address is an antinomy between two apparently contradictory claims, q and ¬q, where we seem equally justified in holding both. The model has the following form: p; q is a necessary condition of p; the only justification we have for q is that it is a necessary condition of p; p is justified only in domain X (where X is a domain of objects of cognition); therefore, q is justified only in domain X. Because the argument shows that our justification for q is valid only in X, it also establishes that there is conceptual space to hold ¬q outside of X.     

An Affordance-Based Approach to Visually Guided Overtaking

When an automobile driver overtakes a lead vehicle while avoiding oncoming traffic, does he or she do so with reference to the limits of his or her car? We investigated overtaking from the perspective of the theory of affordances. We define the overtake-ability affordance as a ratio of the minimum satisfying velocity required for safe overtaking (MSV) to the maximum velocity of the driver's car (V_max). Two groups of participants performed overtaking maneuvers, if deemed possible, by driving either a slow (V_max = 25 m/s) or a fast (V_max = 32.5 m/s) virtual car in overtaking situations constrained by 14 values of MSV. For any given MSV condition, participants in the fast car group were more likely to attempt an overtaking maneuver. However, when MSV was expressed in intrinsic units as a ratio of V_max for both groups, the frequency of overtaking was not significantly different across groups. Furthermore, overtaking frequency dropped to near 0% for both groups when MSV exceeded V_max. In accordance with the affordance-based framework (Fajen, 2007), our results suggest that participants select their overtaking maneuvers by perceiving an overtake-ability affordance.

Differential Method of Characterizing Gait Strategies From Step Lengths and Frequencies: Strategy of Velocity Modulation

The differential method consists of the analysis of the variation of gait parameters length, frequency, and velocity with respect to their mean values, respectively, ΔL = L — L_m , Δf = f — f_m , and Δv = v – v_m , where L_m , f_m , and v_m represent the mean values of those parameters. Assuming that the strategy of modulation of velocity implies that L and f are functions of v and that statistical analyses of ratios ΔL/Δv and Δf/Δv have established that there is a very significant linear correlation, close to 1, between those ratios, the mathematical procedure allows one to determine the equation of step length, L = a · f + b · v + K, where a and b are the slope and the intercept of the linear regression and K is close to L_m . The equation was experimentally tested on 140 gait sequences performed by 6 participants and for gait velocities ranging from 0.6 to 2.2 m/s and was found to be very representative of all individual values. The differential method provides another way of using the derivative of velocity, v = L·f, to characterize the strategy of velocity modulation, which then permits one to determine the linear equation of velocity, v = f · L_m + L · f_m — L_m · f_m , and to show that the respective parts played by each parameter in the progression velocity are approximately equal. The author establishes the uniqueness of the different linear adjustments and discusses the differential method's own modes of use, that is, interindividually or globally.     

Skeptical Conclusions

For a putative knower S and a proposition P, two types of skepticism can be distinguished, depending on the conclusions they draw: outer skepticism, which concludes that S does not know that P, and inner skepticism, which concludes that S does not know whether P. This paper begins by showing that outer skepticism has undesirable consequences because that S does not know that P presupposes P, and inner skepticism does not have this undesirable consequence since that S does not know whether P does not presuppose P. We indicate that the two types of skepticism aim to different loci of doubts: while outer skepticism doubts whether we can gain an epistemic warrant for the actuality, inner skepticism doubts whether we can gain epistemic identification of the actuality. It is further indicated that responses to skepticism from externalist theories, as well as from fallibilist internalist theories, can only respond to outer skepticism but not to inner skepticism.     

Valuation Semantics for First-Order Logics of Evidence and Truth

This paper introduces the logic QLET_F, a quantified extension of the logic of evidence and truth LET_F, together with a corresponding sound and complete first-order non-deterministic valuation semantics. LET_F is a paraconsistent and paracomplete sentential logic that extends the logic of first-degree entailment (FDE) with a classicality operator ∘ and a non-classicality operator ∙, dual to each other: while ∘A entails that A behaves classically, ∙A follows from A’s violating some classically valid inferences. The semantics of QLET_F combines structures that interpret negated predicates in terms of anti-extensions with first-order non-deterministic valuations, and completeness is obtained through a generalization of Henkin’s method. By providing sound and complete semantics for first-order extensions of FDE, K3, and LP, we show how these tools, which we call here the method of anti-extensions + valuations, can be naturally applied to a number of non-classical logics.

     

Autonomy and defensiveness: Experimentally increasing adaptive responses to health-risk information via priming and self-affirmation

Health information is often ineffective in motivating health-behaviour change. One way to improve information effectiveness might be to highlight autonomy, which is associated with less defensiveness and more adaptive psychological functioning. Three studies assessed whether experimentally elevating autonomy led to adaptive responses to risk information about alcohol consumption. In Study 1 (N?=?104), participants completed either an autonomy prime or a neutral prime task and read either risk information about the dangers of alcohol consumption or neutral information. Among high-risk participants in the autonomy prime condition, those who read risk information reported greater autonomous motivation towards moderate alcohol consumption than did those in the neutral information condition. Study 2 (N?=?157) compared two types of autonomy prime tasks with a neutral condition. For high-risk participants who read risk information, the autonomy prime tasks elicited greater autonomous motivation, more positive attitudes and greater intentions to drink in moderation than did the neutral prime task. Study 3 (N?=?130) found that for high-risk participants who read risk information, autonomy prime participants reported less subsequent alcohol consumption than did neutral prime participants. The results are discussed in terms of the benefits of autonomy for adaptive responses to risk information.     

Getting along or ahead: Effects of gender identity threat on communal and agentic self‐presentations

When faced with a threat to gender identity, people may try to restore their gender status by acting in a more gender‐typical manner. The present research investigated effects of gender identity threat on self‐presentations of agentic and communal traits in a Swedish and an Argentine sample (N = 242). Under threat (vs. affirmation), Swedish women deemphasized agentic traits (d [95% CI] = ?0.41 [?0.93, 0.11]), Argentine women increased their emphasis on communal traits (d = 0.44 [?0.08, 0.97]), and Argentine men increased their emphasis on agentic traits (d = 0.49 [?0.03, 1.01]). However, Swedish men did not appear to be affected by the threat regarding agentic (d = 0.04 [?0.47, 0.55]) or communal traits (d = 0.23 [?0.29, 0.74]). The findings are to be considered tentative. Implications for identity threat research are discussed.     

Understanding Asian parenting from a Rasch perspective

This study examines the factor structure of Asian child‐reported parenting from a Rasch perspective. Participants comprised 291 sixth graders (11 to 13 years) in Singapore. Six different aspects of parenting were measured, namely warmth, rejection, structure, chaos, autonomy support, and coercion. Rasch Analysis was used to transform ordinal data into linear measures; category functioning was examined; residual‐based principal components were analysed; differential item functioning was assessed; and items and subjects that were misfitting were removed. Results showed that parenting comprised six dimensions, namely warmth, autonomy support, structure‐control, structure‐warmth, chaos, and negative parenting. The findings suggest that it is important for Asian parents to provide guidance to their children (in structure‐control and structure‐warmth) and reaffirms the relevance of warmth in Asian parenting.     

A Five‐dimensional Model of Attributes: Some precursors of executive coach selection

The purpose of this study was to specify a set of attributes, identified as important precursors to coach selection. Executive coaching has grown exponentially, but there have been few studies as to the efficacy of coaching, including the factors that influence a manager's choice of coach. This study sought to identify these factors. The 45‐item, online survey produced 267 useable responses. Results of the principal component analysis suggested a five‐factor solution, with women showing a statistically significant preference over men for coaches who have the Ability to Develop Critical Thinking and Action, the Ability to Forge the Coaching Partnership and Coach Experience and Qualifications. The impact of coachee age was not significant in selecting executive coaches. The findings show a statistically significant relationship between coach attributes and the intention to continue with coaching. The implications of these findings for the selection of coaches, and for the coaching profession are discussed.
