Material Implication and General Indicative Conditionals 总被引:2,自引:0,他引:2
Stephen Barker 《The Philosophical quarterly》1997,47(187):195-211
This paper falls into two parts. In the first part, I argue that consideration of general indicative conditionals, e.g., sentences like If a donkey brays it is beaten , provides a powerful argument that a pure material implication analysis of indicative if p, q is correct. In the second part I argue, opposing writers like Jackson, that a Gricean style theory of pragmatics can explain the manifest assertability conditions of if p, q in terms of its conventional content – assumed to be merely ( p ⊃ q ) – and the conversational implicature contents which utterance of if p, q may gain in certain contexts. I also defend the pragmatic approach against a recent objection by Edgington that appeal to pragmatics cannot explain what we are inclined to say about the believability conditions, as opposed to the assertability conditions, of indicative if p, q. 相似文献

This paper reviews empirical studies on whether participating in mutual help groups for people with mental health problems leads to improved psychological and social functioning. To be included, studies had to satisfy four sets of criteria, covering: (1) characteristics of the group, (2) target problems, (3) outcome measures, and (4) research design. The 12 studies meeting these criteria provide limited but promising evidence that mutual help groups benefit people with three types of problems: chronic mental illness, depression/anxiety, and bereavement. Seven studies reported positive changes for those attending support groups. The strongest findings come from two randomized trials showing that the outcomes of mutual help groups were equivalent to those of substantially more costly professional interventions. Five of the 12 studies found no differences in mental health outcomes between mutual help group members and non-members; no studies showed evidence of negative effects. There was no indication that mutual help groups were differentially effective for certain types of problems. The studies varied in terms of design quality and reporting of results. More high-quality outcome research is needed to evaluate the effectiveness of mutual help groups across the spectrum of mental health problems. 相似文献

This article examines the role of military chaplains who accompany soldiers on international military and peace-keeping operations, such as those in Iraq, Afghanistan, Kosovo, and Bosnia Herzegovina. It compares and contrasts the two principal traditions of military chaplaincy in the international field—chaplains within the military structure (as in the UK) and parish-based chaplains who remain outside the military (as in Germany). The authors examine the potential conflict between the religious vocation of military chaplains and their role in military operations, which can be particularly contentious from an ethical viewpoint. Interviews with chaplains from both countries provide a unique insight into their experiences. 相似文献

The issue of representing access control requirements continues to demand significant attention. The focus of researchers
has traditionally been on developing particular access control models and policy specification languages for particular applications.
However, this approach has resulted in an unnecessary surfeit of models and languages. In contrast, we describe a general
access control model and a logic-based specification language from which both existing and novel access control models may
be derived as particular cases and from which several approaches can be developed for domain-specific applications. We will
argue that our general framework has a number of specific attractions and an implication of our work is to encourage a methodological
shift from a study of the particulars of access control to its generalities. 相似文献

Variability in subcortical aphasia is due to variable sites of cortical hypoperfusion 总被引:12,自引:0,他引:12
Hillis AE Barker PB Wityk RJ Aldrich EM Restrepo L Breese EL Work M 《Brain and language》2004,89(3):524-530
A variety of fluent and nonfluent aphasias have been reported after left basal ganglia stroke. It has been speculated that this heterogeneity may reflect variations in cortical hypoperfusion resulting from large vessel stenosis. To test this hypothesis, a consecutive series of 24 patients with left caudate infarct identified with diffusion-weighted imaging underwent language testing and perfusion-weighted imaging < 24h from onset of symptoms. Specific regions in perisylvian cortex were rated for the percentage of the region that was hypoperfused. Aphasia type was determined on the basis of speech fluency, comprehension, and repetition performance on the language tests. Association between aphasia type/language impairment and regions of hypoperfusion were identified with Fisher's exact tests. Results demonstrated that in patients with acute left caudate infarct, the presence and type of aphasia reflected regions of hypoperfusion, and generally followed predictions based on chronic lesion studies, regarding anatomical lesions associated with classic aphasia types. 相似文献

Transplantation continues to push the frontiers of medicine into domains that summon forth troublesome ethical questions. Looming on the frontier today is human facial transplantation. We develop criteria that, we maintain, must be satisfied in order to ethically undertake this as-yet-untried transplant procedure. We draw on the criteria advanced by Dr. Francis Moore in the late 1980s for introducing innovative procedures in transplant surgery. In addition to these we also insist that human face transplantation must meet all the ethical requirements usually applied to health care research. We summarize the achievements of transplant surgery to date, focusing in particular on the safety and efficacy of immunosuppressive medications. We also emphasize the importance of risk/benefit assessments that take into account the physical, aesthetic, psychological, and social dimensions of facial disfiguration, reconstruction, and transplantation. Finally, we maintain that the time has come to move facial transplantation research into the clinical phase. 相似文献

This study used a school-based community sample (N=920) to examine trajectories of depressive symptoms, self-esteem, and expressed anger in the critical years of emerging adulthood (ages 18-25). Using data from 5 waves, the authors discovered that multilevel models indicated that, on average, depressive symptoms and expressed anger declined, whereas self-esteem increased. Between-persons predictors of variability in trajectories included gender (gender gaps in depressive symptoms and self-esteem narrowed), parents' education, and conflict with parents (depressive symptoms and expressed anger improved fastest in participants with highly educated parents and in those with higher conflict). Across time, increases in social support and marriage were associated with increased psychological well-being, whereas longer periods of unemployment were connected with higher depression and lower self-esteem. Emerging adulthood is a time of improving psychological well-being, but individual trajectories depend on specific individual and family characteristics as well as role changes. 相似文献

The goal of this study was to examine the links between difficult temperament (i.e., negative emotionality) and harsh parental discipline during toddlerhood, and reactive and proactive aggression in kindergarten. These links were assessed on a longitudinal population-based study of 1516 boys and girls followed longitudinally from the age of 17 months through the age of 72 months. Two possible models were tested to examine the interplay between negative emotionality and harsh parenting in predicting later reactive aggression compared to proactive aggression. The first was an additive model where both aspects make unique contributions in predicting later reactive aggression. The second model was an interactive model where harsh parenting exacerbates the link between negative emotionality and reactive aggression. Results showed a specific contribution of negative emotionality to reactive aggression. The results relative to harsh parenting are more mixed but nonetheless in line with developmental models stressing different pathways to reactive and proactive aggression. 相似文献

A new assessment scheme--the Short-Term Assessment of Risk and Treatability (START)--presents a workable method for assessing risks to self and others encountered in mentally and personality disordered clients. This study aimed to demonstrate (a) prevalence and severity of risk behaviors measured by the START, (b) psychometric properties of START, (c) similarities and differences in START scores across different mental health professionals, and (d) concurrent validity of START with diverse negative outcomes. Treatment team members completed the 20-item, dynamically focused START for 137 forensic psychiatric inpatients. Prevalence and severity of START risk domains were measured for 51 patients detained in the hospital for 1 year. Results revealed high rates of generally low-level adverse events. With some exceptions, START scores were meaningfully associated with outcomes measured by a modified Overt Aggression Scale. 相似文献
