CURIE'S PRINCIPLE

A reading is given of Curie's Principle that the symmetry of a cause is always preserved its effects. The truth of the principle is demonstrated and its importance, under the proposed reading, is defended.As far as I see, all a priori statements in physics have their origin in symmetry. (Weyl, Symmetry, p. 126)     

Closed Causal Loops and the Bilking Argument

The most potentially powerful objection to the possibility oftime travel stems from the fact that it can, under the right conditions, give rise to closedcausal loops, and closed causal loops can be turned into self-defeating causal chains;folks killing their infant selves, setting out to destroy the world before they were born,and the like. It used to be thought that such chains present paradoxes; the receivedwisdom nowadays is that they give rise to physical anomalies in the form of inexplicably correlated events. I argue against the received wisdom. I can find nothing in them that argues against the possibility (even, the probability) of time travel.     

SCIENCE,SPIRITUALITY, AND AYAHUASCA: THE PROBLEM OF CONSCIOUSNESS AND SPIRITUAL ONTOLOGIES IN THE ACADEMY

Ayahuasca is a psychoactive brew from Amazonas, popularized in the last decades in part through transnational religious networks, but also due to interest in exploring spirituality through altered states of consciousness among academic schools and scientific researchers. In this article, the author analyzes the relation between science and religion proposing that the “demarcation problem” between the two arises from the relations among consciousness, intentionality, and spirituality. The analysis starts at the beginning of modern science, continues through the nineteenth century, and then examines the appearance of new schools in psychology and anthropology in the countercultural milieu of the 1960s. The author analyzes the case of ayahuasca against this historical background, first, in the general context of ayahuasca studies in the academic field. Second, he briefly describes three cases from Spain. Finally, he discusses the permeability of science to “spiritual ontologies” from an interdisciplinary perspective, using insights from social and cognitive sciences.     

Severe intimate partner violence risk prediction scale-revised

The aim of this study was to describe the psychometric properties of the Severe Intimate Partner Violence Risk Prediction Scale and to revise it in order to ponderate the 20 items according to their discriminant capacity and to solve the missing item problem. The sample for this study consisted of 450 male batterers who were reported to the police station. The victims were classified as high-risk (18.2%), moderate-risk (45.8%) and low-risk (36%), depending on the cutoff scores in the original scale. Internal consistency (Cronbach's alpha=.72) and interrater reliability (r=.73) were acceptable. The point biserial correlation coefficient between each item and the corrected total score of the 20-item scale was calculated to determine the most discriminative items, which were associated with the context of intimate partner violence in the last month, with the male batterer's profile and with the victim's vulnerability. A revised scale (EPV-R) with new cutoff scores and indications on how to deal with the missing items were proposed in accordance with these results. This easy-to-use tool appears to be suitable to the requirements of criminal justice professionals and is intended for use in safety planning. Implications of these results for further research are discussed.     

Quantum holism: nonseparability as common ground

Quantum mechanics seems to portray nature as nonseparable, in the sense that it allows spatiotemporally separated entities to have states that cannot be fully specified without reference to each other. This is often said to implicate some form of “holism.” We aim to clarify what this means, and why this seems plausible. Our core idea is that the best explanation for nonseparability is a “common ground” explanation (modeled after common cause explanations), which casts nonseparable entities in a holistic light, as scattered reflections of a more unified underlying reality.

     

Using latent class growth analysis to form trajectories of premorbid adjustment in schizophrenia

Premorbid adjustment varies widely among individuals with schizophrenia and has been shown to bear significantly on prodrome and onset characteristics, and on cognition, symptoms, and functioning after onset. The current analysis focused on the Premorbid Adjustment Scale, a retrospective measure assessing social and academic function at several time points from early childhood to illness onset. In an effort to explore discrete developmental subtypes, we applied latent class growth analysis to data from the Premorbid Adjustment Scale in our sample of individuals with schizophrenia (N = 208), finding three latent trajectory classes. The first of these classes showed consistently adequate-to-good social and academic functioning before onset; the second showed initially good function and deterioration with time until onset; the third showed poor functioning in childhood that deteriorated further during the years up to diagnosis. The classes differed significantly in terms of age of onset, processing speed, and functioning after onset. There were no significant differences in symptomatology. Our findings illustrate a potentially powerful methodological approach to the problem of heterogeneity in schizophrenia research, and add weight to the notion that aspects of premorbid history may be useful for subtyping schizophrenia patients. The potential implications of this subtyping strategy, including those pertaining to potential genetics studies, are discussed.     

Understanding childcare satisfaction and its effect on workplace outcomes: The convenience factor and the mediating role of work‐family conflict

Building on Hobfoll's (1989, 2001) conservation of resources theory, we posit childcare is an essential resource to working parents. In addition to previously demonstrated childcare satisfaction (CCS) dimensions, we propose and demonstrate empirical support for a convenience dimension of CCS. Satisfaction with caregiver convenience refers to a parent's evaluation of the caregiver's location and availability. We hypothesize that time‐related dimensions of CCS (caregiver dependability and convenience) relate to employee well‐being and withdrawal, because they diminish time‐based family interfering with work (FIW). We also propose quality‐related CCS dimensions (caregiver attentiveness, communication, and cost) relate to psychological well‐being, because they reduce strain‐based FIW. Survey data from a sample of 316 university employees (faculty and staff) who were parents of under school‐age children (infancy through preschool) revealed time‐based FIW as an explanatory mechanism for the relationships between satisfaction with caregiver convenience and both turnover intentions and absenteeism (due to childcare issues). In addition, strain‐based FIW mediated the effects of satisfaction with caregiver attentiveness on well‐being and satisfaction with caregiver cost on well‐being. This study expands previous research on CCS by demonstrating that CCS is related to important work outcomes in part because it reduces time‐ and strain‐based FIW.     

The neuropsychology of religious experience. A review of different scientific approaches to the phenomenon / Neuropsicología de la experiencia religiosa. Una revisión de distintas aproximaciones científicas al fenómeno

Abstract

The current article is a critical review of the neuropsychological study of religious experience. First, we analyse the philosophical and theological roots of the term and its characterization as a sui generis and unique phenomenon. We subsequently describe the adoption of the concept in psychology, as well as the emergence of alternative approaches that emphasize the role of categorization of experiences as religious. We then move on to explore how both approaches have influenced the neuropsychological study of religious experience, consequently producing different models: sui generis, attributional and others that consider the variety of factors and the heterogeneity of experiences associated with religious practices.     

The empirical investigation of factors affecting graphical visualization

An estimated 2.2 trillion graphs were published during 1994. These graphs used a multitude of different visual techniques in an effort to communicate information to a reader. Despite the many important applications for which graphs are used and the frequency of their use, little is known about what techniques make a graph most effective at communicating information to a reader. This paucity of knowledge stems largely from a dearth of empirical investigations pertaining to graphs. A major problem encountered by researchers who wish to undertake sound empirical research into the effectiveness of graphical presentations is the shortage of suitable tools. This article presents a computer software tool, Graphics Visualization, which offers the researcher an inexpensive yet accurate and reliable method of performing empirical research into factors that affect the accuracy and speed by which a reader can interpret data encoded within a graph.     

Psychometric properties of the Shared Decision-Making Questionnaire (SDM-Q-9) in oncology practicePropiedades psicométricas del Questionnaire Shared Decision-Making (SDM-Q-9) en oncología

Background/Objective: This study sought to assess the psychometric properties of the 9-item Shared Decision-Making Questionnaire (SDM-Q-9) in patients with resected, non-metastatic cancer and eligible for adjuvant chemotherapy. Method: A total of 568 patients were recruited from a multi-institutional, prospective, transversal study. Patients answered the SDM-Q-9 after visiting their medical oncologist who, in turn, completed the SDM-Q–Physician version. Reliability, factorial structures [exploratory factor analysis (EFA), confirmatory factor analysis (CFA)], and convergent validity of the SDM-Q-9 scores were explored. Results: SDM-Q-9 showed a clear factorial structure, compatible with a strong and replicable general factor and a secondary group factor, in patients with resected, non-metastatic cancer. Total sum scores derived from the general factor showed good reliability in terms of omega coefficient: .90. The association between patient and physician perception of SDM was weak and failed to reach statistical significance. Males and patients over 60 years of age displayed the greatest satisfaction with SDM. Conclusions: SDM-Q-9 can aid in evaluating SDM from the cancer patients’ perspective. SDM-Q-9 is helpful in studies examining patient perspectives of SDM and as an indicator of the degree of quality and satisfaction with health care and patient-physician relationship.
