Hardiness and health among women with rheumatoid arthritis

The relations among hardiness (and its components) and demographic variables, objective health, disability, and perceived health were investigated for 33 women with rheumatoid arthritis. Hardiness and demographic variables were measured once while objective health, disability, and perceived health were measured at three monthly intervals. Hardiness and/or component scores were significantly (P < 0.05) related to age and to employment status but were unrelated to education and to marital status. The control dimension of hardiness was positively correlated with the average percentage of circulating T-cells (r = 0.38, P < 0.05), and with average perceived health compared to one's same age peers (r = 0.53, P < 0.01). Hardiness appears to be a useful construct for understanding adaptation to rheumatoid arthritis, and studies of patients with chronic diseases can shed light on the precursors and consequences of hardiness.     

The cultural approach of ethnopsychiatry: A review and critique

Ethnopsychiatrists have consistently maintained that the perceptions, inclinations, and behavior of mentally ill persons are never a simple reflection of their illness: the mentally ill tend to behave in some ways in some cultural contexts and in other ways in others. This pathoplasticity shows, we are told, that abnormality is, primarily, the manifestation of a phenotype, not a genotype. Hence, any diagnosis and treatment of the affected individual must be grounded in some knowledge of the environment within which he or she functions. Postulating the existence of such an intimate and harmonious connection between psychopathology and social conditions, however, overlooks a pivotal distinction: while it is true that local norms and values can and do affect most neurotic presentations, those same standards have at best a marginal influence on psychotic reactions. Some pathogenic features are so overwhelming that they will be expressed in any environment. Accordingly, I conclude, we shall have progressed significantly in our understanding of the nature of mental disorders once we begin to associate neuroses with culture and psychoses with biology.     

Hardiness: a review of theory and research.

Although a large body of research on hardiness (a personality construct with dimensions of commitment, control, and challenge) has accumulated, several fundamental issues remain unresolved. Although there are several hardiness scales, the properties of these scales have not been compared. There is debate as to whether hardiness is one or several characteristics. Research studying the pathways through which hardiness exerts its effects has not been comprehensively evaluated. Whereas critics have argued that hardiness does not buffer stress, others have suggested that hardiness buffers for working adults, for males, and in prospective analyses. There is also growing concern that hardiness is related to neuroticism. A review of the literature supports the following conclusions: The Dispositional Resilience Scale (DRS) has several advantages over alternative scales; DRS items form three factors that are consistent with hardiness theory; hardiness dimensions generally show low to moderate intercorrelations; the most common way of categorizing subjects as high or low in hardiness is not consistent with hardiness theory; hardiness does not buffer stress, and it does not buffer stress for working adults, for males, or in prospective analyses; both old and new hardiness scales inadvertently measure neuroticism. Recommendations for future research are provided.     

Hardiness and stress moderation: a test of proposed mechanisms

High and low hardy male and female undergraduates completed an evaluative threat task that was manipulated to influence appraisals of the task in a manner consistent with hardiness theory. High hardy subjects displayed higher frustration tolerance, appraised the task as less threatening, and responded to the task with more positive and less negative affect than did low hardy subjects. Although all subjects displayed increased heart rate (HR) in response to the experimental task, high hardy men displayed lower HR elevations during the task than did low hardy men. Hardiness did not influence HR responses among women. Manipulations of task appraisal revealed a similar pattern where men in the high hardiness appraisal conditions displayed lower levels of physiological arousal during the task than did men in the low hardiness appraisal conditions. Appraisal manipulations had either no effect or the opposite effect among women.     

Verbal probabilities: An alternative approach

Previous studies of verbal probabilities have tried to place expressions like a chance, possible, and certain on 0–1 numerical probability scales. We ask instead, out of a range of outcomes, which outcome a verbal probability suggests. When, for instance, a sample of laptop batteries lasts from 1.5 to 3.5 hours, what is a certain and what is a possible duration? Experiment 1 showed that speakers associate certain with low values and possible with (unlikely) high or maximal values. In Experiment 2, this methodology was applied to several positive and negative verbal probability phrases, showing a preference for high rather than low or middle values in a distribution. Experiment 3 showed that such maxima are not universally described by large numbers. For instance, maximum speed is often described in terms of a small number of time units. What can (possibly) happen is accordingly sometimes described with very low and sometimes with very high values, depending upon focus of interest. Finally, participants in Experiment 4 were given the role of hearers rather than speakers and were asked to infer outcome ranges from verbal probabilities. Hearers appeared to be partly aware of speakers' tendencies to describe outcomes at the top of the range.     

Principles of early stopping of randomized trials for efficacy: a critique of equipoise and an alternative nonexploitation ethical framework

Recent controversial decisions to terminate several large clinical trials have called attention to the need for developing a sound ethical framework to determine when trials should be stopped in light of emerging efficacy data. Currently, the fundamental rationale for stopping trials early is based on the principle that equipoise has been disturbed. We present an analysis of the ethical and practical problems with the "equipoise disturbed" position and describe an alternative ethical framework based on the principle of nonexploitation. This framework acknowledges the need for balancing the dual ethical obligations of clinical research, the protection of human subjects and the generation of new medical knowledge. Based on this framework, we put forward a proposal to make early stopping guidelines more stringent under specified conditions. The temporary withholding of apparent benefits in certain circumstances is justified by achieving a fair contract with the research participants, one that protects them from undue harm and exploitation while reducing the many uncertainties surrounding new investigational treatments that arise when trials are stopped prematurely.     

Concept empiricism: a methodological critique

Thanks to Barsalou's, Damasio's, Glenberg's, Prinz' and others' work, neo-empiricism is gaining a deserved recognition in the psychology and philosophy of concepts. I argue, however, that neo-empiricists have underestimated the difficulty of providing evidence against the amodal approach to concepts and higher cognition. I highlight three key problems: the difficulty of sorting out amodal predictions from neo-empiricist predictions, the difficulty of finding experimental tasks that are not best solved by imagery and the difficulty of generalizing findings concerning a given cognitive process in a given context to other cognitive processes or other contexts. Finally, solutions to these three problems are considered.     

Fichte’s critique of physicalism – towards an idealist alternative

ABSTRACT

Though the perennial problem of consciousness has outlasted the idealists, the reductivist turn in contemporary naturalistic philosophy of mind and the non-reductivist reactions to it provoke us to re-think post-Kantian idealism. Fichte's Wissenschaftslehre makes for a classical case of non-reductivist (and probably even non-naturalist) approach to mind and his critique of ‘dogmatism’ is all the more relevant in this context. This article contains four sections. The first section is an introduction that explains why post-Kantian idealism is relevant to contemporary philosophy of mind. The second section pinpoints the placement issue that confronts not only current philosophers but also partially motivated Fichte's own philosophy. The third section is a short but essential remark about the normative and practical valence of ‘knowledge’ and ‘science’ in Fichte's traditional understanding of them. In the fourth section, I provide a reconstructive analysis of Fichte's understanding and critique of physicalism. Fichte's argument can be analyzed into two horns with each targeting reductivism and epiphenomenalism respectively. The final section is a brief but positive exposition on a necessary feature, namely reflexivity, of mind and the first-person perspective. Fichte's appropriation of intellectual intuition exemplifies a non-representationalist picture that connects content transparency with the active nature of mind.     

Reduction and emergence: a critique of Kim

In a recent critique of the doctrine of emergentism championed by its classic advocates up to C. D. Broad, Jaegwon Kim (Philosophical Studies 63:31–47, 1999) challenges their view about its applicability to the sciences and proposes a new account of how the opposing notion of reduction should be understood. Kim is critical of the classic conception advanced by Nagel and uses his new account in his criticism of emergentism. I question his claims about the successful reduction achieved in the sciences and argue that his new account has not improved on Nagel’s and that the critique of emergentism he bases on it is question-begging in important respects.     

Acute stress disorder: a synthesis and critique

The diagnosis of acute stress disorder (ASD) was introduced to describe initial trauma reactions that predict chronic posttraumatic stress disorder (PTSD). This review outlines and critiques the rationales underpinning the ASD diagnosis and highlights conceptual and empirical problems inherent in this diagnosis. The authors conclude that there is little justification for the ASD diagnosis in its present form. The evidence for and against the current emphasis on peritraumatic dissociation is discussed, and the range of biological and cognitive mechanisms that potentially mediate acute trauma response are reviewed. The available evidence indicates that alternative means of conceptualizing acute trauma reactions and identifying acutely traumatized people who are at risk of developing PTSD need to be considered.
