There are at least eight good reasons practicing historians should concern themselves with counterfactual claims. Furthermore, four of these reasons do not even require that we are able to tell which historical counterfactuals are true and which are false. This paper defends the claim that these reasons to be concerned with counterfactuals are good ones, and discusses how each can contribute to the practice of history.  相似文献

In several disciplines within science—evolutionary biology, molecular biology, astrobiology, synthetic biology, artificial life—and outside science—primarily ethics—efforts to define life have recently multiplied. However, no consensus has emerged. In this article, I argue that this is no accident. I propose a dilemma showing that the project of defining life is either impossible or pointless. The notion of life at stake in this project is either the folk concept of life or a scientific concept. In the former case, empirical evidence shows that life cannot be defined. In the latter case, I argue that, although defining life may be possible, it is pointless. I conclude that scientists, philosophers, and ethicists should discard the project of defining life.  相似文献

This work examines the aggregation of justice perceptions to the departmental level and the business-unit level, the impact of these aggregate perceptions on business-unit-level outcomes, and the usefulness of the distinction between procedural and interpersonal justice at different levels of analysis. Latent variables analyses of individual-level and department-level data from 4,539 employees in 783 departments at 97 hotel properties showed that the 2 justice types exercise unique paths of impact on employees' organizational commitment and thus on turnover intentions and discretionary service behavior. Business-unit-level analyses further demonstrate paths of association between aggregate justice perceptions, aggregate commitment levels, and the business-unit-level outcomes of employee turnover rates and customer satisfaction ratings.  相似文献

Although nothing could be less fashionable today than talk of comprehensive health care reform, the major problems of American health care have not gone away. Only a radical change in the way the U.S. finances health care--specifically, a single-payer system--will permit the achievement of universal coverage while keeping costs reasonably under control. Evidence from other countries, especially Canada, suggests the promise of this approach. In defending the single-payer approach, the author identifies several political and cultural factors that make it difficult for Americans to obtain a clear view of this option. Finally, the author argues that much discussion of rationing is vitiated by bracketing more systemic questions to which the issue of rationing is inextricably linked.  相似文献

This paper proposes an approach to spiritual education which transcends the religious-secular boundary by conceiving of spirituality as a natural human predisposition labelled 'relational consciousness'. Evidence drawn from recent research demonstrates that this predisposition is universally identifiable in young children and expresses itself in many forms apart from the religious. Nevertheless it is this which allows the possibility of religious belief. As a result of the cultural construction of an extreme individualism which is particularly evident in the Western world, there has been a 'forgetting' of relational consciousness/spirituality resulting in damaging effects to the texture of human community. Some major sources of individualism are identified as having particularly serious effects on relational consciousness. These are reflected upon in the light of empirical research on children as well as contemporary philosophical and political critiques. Spiritual education is seen as a major means of resistance to the damaging effects of possessive individualism.  相似文献

This article argues that psychiatric diagnoses are not valid or useful. The use of psychiatric diagnosis increases stigma, does not aid treatment decisions, is associated with worsening long-term prognosis for mental health problems, and imposes Western beliefs about mental distress on other cultures. This article reviews the evidence base focusing in particular on empirical findings in relation to the topics of: aetiology, validity, reliability, treatment and outcome, prognosis, colonialism, and cultural and public policy impact. This evidence points toward diagnostic based frameworks for understanding and intervening in mental health difficulties being unable to either improve our scientific knowledge or improve outcomes in clinical practice and suggests that we need to move away from reliance on diagnostic based approaches for organising research and service delivery. Alternative evidence-based models for organising effective mental health care are available. Therefore formal psychiatric diagnostic systems such as the mental health section of the International Classification of Diseases Tenth Edition (ICD-10) and Diagnostic Statistical Manual Fifth Edition (DSM 5) should be abolished.  相似文献

Skeptical hypotheses such as the brain-in-a-vat hypothesis provide extremely poor explanations for our sensory experiences. Because these scenarios accommodate virtually any possible set of evidence, the probability of any given set of evidence on the skeptical scenario is near zero; hence, on Bayesian grounds, the scenario is not well supported by the evidence. By contrast, serious theories make reasonably specific predictions about the evidence and are then well supported when these predictions are satisfied.  相似文献

Patristic teaching about sin and disease allows supplementing well-acknowledged conditions for a Christian medicine with further personal challenges, widely disregarded in Western Christianities. A proper appreciation of man's vocation toward (not just achieving forgiveness but) deification reveals the need to cooperate with the Holy Spirit's offer of grace toward restoring man's pre-fallen nature. Ascetical exercises designed at re-establishing the spirit's mastery over the soul distance persons from (even supposedly harmless) passion. They thus inspire the struggle towards emulating Christ's (self-crucifying) kenotic love, and to accept even secularly "undeserved" suffering as spiritually deserved in view of his (forever) lacking fervor in that struggle. Only in the spirit of that love can the evil Adam's sin brought into this world work its therapeutic impact, the eschatological purpose of which explains God's lovingly permitting that evil. This therapeutic impact is physically manifested already in this life through the transforming energies granted the saints of the church.  相似文献

Two appetitive conditioning experiments with rats examined reacquisition after conditioned responding was eliminated by either extinction or by a partial reinforcement procedure in which reinforced trials were occasionally presented among many nonreinforced trials. In Experiment 1, reacquisition to a conditional stimulus (CS) that had been conditioned and extinguished was more rapid than acquisition in a group that had received no prior conditioning. However, the addition of occasional reinforced trials to extinction slowed this rapid reacquisition effect. Experiment 2 replicated the result and showed that a procedure in which the CS and the unconditional stimulus (US) were unpaired in extinction interfered even further with reacquisition. The results suggest that rapid reacquisition is ordinarily produced when reinforced trials provide a contextual cue that can renew responding by signaling other acquisition trials (Ricker & Bouton, 1996). The effects of partial reinforcement in extinction are surprising from several theoretical perspectives and have useful clinical implications.  相似文献

Previous research on gaze behaviour in sport has typically reported summary fixation statistics thereby largely ignoring the temporal sequencing of gaze. In the present study on penalty kicking in soccer, our aim was to apply a Markov chain modelling method to eye movement data obtained from goalkeepers. Building on the discrete analysis of gaze employed by Dicks et al. (Atten Percept Psychophys 72(3):706–720, 2010b), we wanted to statistically model the relative probabilities of the goalkeeper’s gaze being directed to different locations throughout the penalty taker’s approach (Dicks et al. in Atten Percept Psychophys 72(3):706–720, 2010b). Examination of gaze behaviours under in situ and video-simulation task constraints reveals differences in information pickup for perception and action (Attention, Perception and Psychophysics 72(3), 706–720). The probabilities of fixating anatomical locations of the penalty taker were high under simulated movement response conditions. In contrast, when actually required to intercept kicks, the goalkeepers initially favoured watching the penalty taker’s head but then rapidly shifted focus directly to the ball for approximately the final second prior to foot-ball contact. The increased spatio-temporal demands of in situ interceptive actions over laboratory-based simulated actions lead to different visual search strategies being used. When eye movement data are modelled as time series, it is possible to discern subtle but important behavioural characteristics that are less apparent with discrete summary statistics alone.  相似文献

Four experiments are reported in which the amount of CRF training prior to extinction is examined as it effects transient changes in response frequency and duration immediately following extinction onset. The first two experiments, using albino rats as subjects and water reinforcement, revealed a reliable relationship between length of time on CRF and the tendency to increase response frequency, duration, and the variability of response frequency and duration. Two comparative experiments were conducted using 53-to-69-month old children as subjects, and recorded music as reinforcement. The results of the first child study failed to conform with those obtained in the rat experiments. However, manipulation of the reinforcer in a subsequent study reproduced the rat extinction effect. Despite the differences in the rat and child experiments, the qualitative similarity of the results of the four studies suggests a basic underlying comparability of the relationship between the amount of training and transient changes in response frequency.  相似文献

In this paper a five years analysis of psychotherapy is done. The sample, taken from the PsycLIT was composed of 2694 books and book's chapters which deal with psychotherapy from many perspectives. Results are offered about first author's sex, institutional affiliation and country. Besides, the content of each book and chapter is analyzed in terms of the therapeutic approach followed, the pathology and sample treated, and the specific theme or author's work reviewed. The paper ends with a thorough discussion of the most relevant results found and brief comments about the future of psychotherapy.  相似文献
