Social support,coping, and depressive symptoms in cardiac illness among Hispanic and non-Hispanic White cardiac patients

In Multi-Trait Multi-Method (MTMM) studies of causal attributions for laboratory events, there is little evidence of convergent and discriminant validity for attribution measures. We report the first MTMM study to investigate the validity of two methods of eliciting causal beliefs for an illness, specifically, myocardial infarction. Adult respondents (N?=?107) listed causes of MI, then completed questionnaire rating scales for causal beliefs for MI. Measures were compared using both Campbell and Fiske's approach to MTMM analyses, and a Confirmatory Factor Analysis approach. Neither single item measures causal beliefs, nor scales of causal beliefs derived using exploratory factor analysis provided much evidence of convergent and discriminant validity. Confirmatory factor analysis showed that a model containing only causal belief factors provided a moderately good fit to the data. Adding a questionnaire method factor significantly improved the fit of the model, as well as substantially changing the pattern of factor loadings: loadings of questionnaire items on causal belief factors were markedly reduced. These results highlight major problems with the measurement of causal beliefs, and in particular question the validity of factor analysis of questionnaire measures of causal beliefs. They also suggest that at least some of the MI causal belief factors reported in the literature are artefacts of common questionnaire method variance.     

AC loss density component in electrical steel sheets

This article proposes a new approach to the loss separation issue. The conventional loss separation into three components is abandoned. The dependence of the dynamic component of loss density versus frequency is assumed to be a power law. The model is verified for selected samples of nonoriented and grain-oriented steel.     

Objections and replies within the fifth meditation

Malebranche held that God acts only by general volitions and so is not constantly interfering in the world. The content of God's volitions appears to include the general laws of nature and the particular initial configuration of the created world, so that occasional or natural causes have an important explanatory role. It is clear that at the least Malebranche meant by a ‘general volition’ the willing of events which followed general laws. Steven Nadler argued that this is all we should understand by a ‘general volition’, and so we should think that general volitions are simply particular volitions which follow a general law.

I argue that this view is not the correct interpretation of Malebranche's general volitions, for it does not do justice to the theological doctrine of the Treatise, masks the genuine difference between Arnauld and Malebranche, and conflicts with what Malebranche says about practical volitions. I then argue that despite Malebranche's view of general volitions, there is still an important difference between his view and Leibniz's.     

The Causal Closure of Physics: An Explanation and Critique

Bistable, autonomously growing and self‐maintaining dynamical systems possess a new mathematical and applicational aspect: they can switch toward (physical) existence. Larger dynamical systems containing such flip‐flops as subsystems are frequent. The mathematical prototype is a special type of Z₂‐networks, termed a competence automaton. A chemical implementation is the ‘magic soup.’ It constitutes a general model for life‐type evolution processes including economic evolution.     

Mapping the Structure of Semantic Memory

Aggregating snippets from the semantic memories of many individuals may not yield a good map of an individual’s semantic memory. The authors analyze the structure of semantic networks that they sampled from individuals through a new snowball sampling paradigm during approximately 6 weeks of 1‐hr daily sessions. The semantic networks of individuals have a small‐world structure with short distances between words and high clustering. The distribution of links follows a power law truncated by an exponential cutoff, meaning that most words are poorly connected and a minority of words has a high, although bounded, number of connections. Existing aggregate networks mirror the individual link distributions, and so they are not scale‐free, as has been previously assumed; still, there are properties of individual structure that the aggregate networks do not reflect. A simulation of the new sampling process suggests that it can uncover the true structure of an individual’s semantic memory.     

The selective power of causality on memory errors

We tested the influence of causal links on the production of memory errors in a misinformation paradigm. Participants studied a set of statements about a person, which were presented as either individual statements or pairs of causally linked statements. Participants were then provided with causally plausible and causally implausible misinformation. We hypothesised that studying information connected with causal links would promote representing information in a more abstract manner. As such, we predicted that causal information would not provide an overall protection against memory errors, but rather would preferentially help in the rejection of misinformation that was causally implausible, given the learned causal links. In two experiments, we measured whether the causal linkage of information would be generally protective against all memory errors or only selectively protective against certain types of memory errors. Causal links helped participants reject implausible memory lures, but did not protect against plausible lures. Our results suggest that causal information may promote an abstract storage of information that helps prevent only specific types of memory errors.     

Competence

Summary

Competence in mental health is explored in many roles, including that of researcher, author, teacher, supervisor, therapist, evaluator, consultant, forensic specialist, case manager, and administrator. It is viewed not only as a construct but also as an ongoing process within the individual. Five fundamental areas are examined: (1) Maintaining high standards of competence, (2) keeping within one's boundaries of competence and limitations of one's expertise, (3) maintaining competence in human diversity in practice and research, (4) engaging in continuing education in scientific and professional areas, and (5) protecting the welfare of others when standards are lacking. Guidance is also received from ethics codes, published standards of practice, federal and state laws, and institutional policies and regulations.     

Visual impressions of forces between objects: Entraining,enforced disintegration,and shattering

When a moving object (A) contacts a stationary one (B) and Object B then moves, visual impressions of force occur along with a visual impression of causality. It is shown that findings about force impressions that occur with launching effect stimuli generalize to other forms of phenomenal causality, namely entraining, enforced disintegration, and shattering stimuli. In particular, evidence is reported for generality of the force asymmetry, in which the amount of perceived force exerted by Object A is greater than the amount of perceived resistance put up by Object B. Effects of manipulations of kinematic variables also resembled those found in previous experiments. Some unpredicted findings occurred. It is argued that these reflect a change in perceptual interpretation when both objects are in motion prior to contact, due to both objects being perceived as in autonomous motion. The results are consistent with a theoretical account in which force impressions occur by a process of matching kinematic information in visual stimuli to stored representations of actions on objects, which supply information about forces.     

Les soignants face au burnout : quelles attributions causales ?

The objective of this study was to investigate the nature of the explanations produced by nurses when they are questioned about professional situations related with professional exhaustion such as burnout (BO), independently of a real-life situation of BO. The analysis of the 30 nurses’ adherences to causal explanations scale constructed and validated for this purpose showed greater adherence to internal causal explanations, both controllable and non-controllable, as explanations under external causalities, whatever the professional situation mentioned. The discussion focuses on the relevance of a psychosocial approach of explanations of the BO situations and its implications in terms of primary prevention of psychosocial risks in occupational context.
