Psychometric Characteristics of the Wish to Be Dead Scale (WDS) in Iranian Psychiatric Outpatients

The Wish to be Dead Scale (WDS) was administered to a convenience sample of 200 Iranian psychiatric outpatients. Using a Principal Component Analysis, two factors were identified, labeled Lack of purpose in life (F1), and Lack of interest in living (F2). The WDS had good reliability and significant positive correlations with scores on the Beck Suicide Ideation Scale and with other measures of mental ill-health. This study provides evidence of the usefulness of the WDS for assessing psychiatric patients.     

Identity Theft in the Academic World Leads to Junk Science

In recent years, identity theft has been growing in the academic world. Cybercriminals create fake profiles for prominent scientists in attempts to manipulate the review and publishing process. Without permission, some fraudulent journals use the names of standout researchers on their editorial boards in the effort to look legitimate. This opinion piece, highlights some of the usual types of identity theft and their role in spreading junk science. Some general guidelines that editors and researchers can use against such attacks are presented.     

Doing the Right Thing: A Qualitative Investigation of Retractions Due to Unintentional Error

Retractions solicited by authors following the discovery of an unintentional error—what we henceforth call a “self-retraction”—are a new phenomenon of growing importance, about which very little is known. Here we present results of a small qualitative study aimed at gaining preliminary insights about circumstances, motivations and beliefs that accompanied the experience of a self-retraction. We identified retraction notes that unambiguously reported an honest error and that had been published between the years 2010 and 2015. We limited our sample to retractions with at least one co-author based in the Netherlands, Belgium, United Kingdom, Germany or a Scandinavian country, and we invited these authors to a semi-structured interview. Fourteen authors accepted our invitation. Contrary to our initial assumptions, most of our interviewees had not originally intended to retract their paper. They had contacted the journal to request a correction and the decision to retract had been made by journal editors. All interviewees reported that having to retract their own publication made them concerned for their scientific reputation and career, often causing considerable stress and anxiety. Interviewees also encountered difficulties in communicating with the journal and recalled other procedural issues that had unnecessarily slowed down the process of self-retraction. Intriguingly, however, all interviewees reported how, contrary to their own expectations, the self-retraction had brought no damage to their reputation and in some cases had actually improved it. We also examined the ethical motivations that interviewees ascribed, retrospectively, to their actions and found that such motivations included a combination of moral and prudential (i.e. pragmatic) considerations. These preliminary results suggest that scientists would welcome innovations to facilitate the process of self-retraction.     

Psychosocial profile of people with AIDS and their caregivers in Egypt

Caring for individuals with AIDS in developing countries represents a major crisis to families and natural caregivers. This study presents the psychosocial profiles of people with AIDS and their caregivers in Egypt to assess the effects of HIV/AIDS on patients, their caregivers, and the factors that influence caregiving and support. Various stressors and challenges for patients as well as hardships the caregiver faces were explored. The literature documents difficulties such as inadequate health care services, lack of resources, and stigma that patients experience in developing countries. Findings indicate an association between the psychosocial effects of AIDS on patients and their caregivers.     

Activation of cannabinoid CB1 receptors in the central amygdala impairs inhibitory avoidance memory consolidation via NMDA receptors

In the present study, we investigated the influence of bilateral intra-central amygdala (intra-CeA) microinjections of N-methyl-d-aspartate (NMDA) receptor agents on amnesia induced by a cannabinoid CB1 receptor agonist, arachydonilcyclopropylamide (ACPA). This study used a step-through inhibitory (passive) avoidance task to assess memory in adult male Wistar rats. The results showed that intra-CeA administration of ACPA (2 ng/rat) immediately after training decreased inhibitory avoidance (IA) memory consolidation as evidenced by a decrease in step-through latency on the test day, which was suggestive of drug-induced amnesia. Post-training intra-CeA microinjections of NMDA (0.0001, 0.001 and 0.01 μg/rat) did not affect IA memory consolidation. However co-administration of NMDA with ACPA (2 ng/rat) prevented the impairment of IA memory consolidation that was induced by ACPA. Although post-training intra-CeA administration of the NMDA receptor antagonist, d-(−)-2-amino-5-phosphonopentanoic acid (d-AP5; 0.01, 0.05 and 0.1 μg/rat) alone had no effect, its co-administration with an ineffective dose of ACPA (1 ng/rat) impaired IA memory consolidation. Post-training intra-CeA microinjection of an ineffective dose of d-AP5 (0.01 μg/rat) prevented an NMDA response to the impaired effect of ACPA. These results suggest that amnesia induced by intra-CeA administration of ACPA is at least partly mediated through an NMDA receptor mechanism in the Ce-A.     

Social skills, friendship and happiness: a cross-cultural investigation

The present study investigated the associations between social skills, friendship quality, and happiness, and tested a mediational model positing that friendship quality would mediate the relationship between social skills and happiness among American and Malaysian college students. Although American students reported significantly higher levels of psychosocial well-being than Malaysian students, the study variables were positively associated with each other in both cultures. More importantly, findings supported the proposed model in both groups. Results suggest that part of the reason why social skills are associated with positive psychological well-being is because of friendship experiences. Overall, the findings of the present study reinforce, extend and cross-culturally generalize the presumed benefits of social skills in positive well-being elaborated by Segrin and Taylor (2007). The authors also provided suggestions for future research.     

A biologically based model for recognition of 2-D occluded patterns

In this work, we present a biologically inspired model for recognition of occluded patterns. The general architecture of the model is based on the two visual information processing pathways of the human visual system, i.e. the ventral and the dorsal pathways. The proposed hierarchically structured model consists of three parallel processing channels. The main channel learns invariant representations of the input patterns and is responsible for pattern recognition task. But, it is limited to process one pattern at a time. The direct channel represents the biologically based direct connection from the lower to the higher processing level in the human visual cortex. It computes rapid top-down pattern-specific cues to modulate processing in the other two channels. The spatial channel mimics the dorsal pathway of the visual cortex. It generates a combined saliency map of the input patterns and, later, segments the part of the map representing the occluded pattern. This segmentation process is based on our hypothesis that the dorsal pathway, in addition to encoding spatial properties, encodes the shape representations of the patterns as well. The lateral interaction between the main and the spatial channels at appropriate processing levels and top-down, pattern-specific modulation of the these two channels by the direct channel strengthen the locations and features representing the occluded pattern. Consequently, occluded patterns become focus of attention in the ventral channel and also the pattern selected for further processing along this channel for final recognition.     

What Does Islam Say About Dieting?

Dieting is very important to maintain a healthy and peaceful life. Today, most of the health problems are related with dieting. Thus, the modern health science recommends a number of suggestions regarding dieting for better health such as learning the five basic food groups (grains, vegetables, fruits, dairy, and meat); eating three times a day; decreasing the amount of fat; increasing the amount of fruits, vegetables and grains; including an adequate amount of iron; and avoiding excessive rich food, salt, sugar, and fat. Religion can also play a vital role for our good health and lifestyle. The main concern of this paper was to present an analytical justification regarding what Islam as a religion advocates about dieting along with the modern food and nutrition sciences.     

Alston's Anti‐Justificationism as a Strategy to Resolve the Conflict Between Internalism and Externalism

After a justificationist period, William P. Alston has tried to eliminate justification from the epistemology of belief. He introduced a list of epistemic desiderata all of which contribute to the positive status of beliefs and none of which has an exclusive and decisive role so that it could be isolated as the property of being justified. Careful examination reveals, however, that this list includes fewer desiderata than advertised. Truth‐conducive desiderata are most important for Alston, and these are five; during his discussion, however, Alston reduces these desiderata to only one, the reliability of process, which has an externalist character. Besides this desideratum, there is one other group of desiderata, all of which have an internalist character. What Alston has in fact done, then, through the presentation of his anti‐justificationist list, is to separate externalist and internalist elements for the positive status of belief and to give an independent role to each. Since Alston regards the truth‐conducive group as the most important, however, and since he has failed to show a real pluralism in this group, we may conclude that he continues to have a monistic approach to the evaluation of beliefs, which belies his alleged pluralism.     

The impact of a laryngectomy on the spouse: Who is better off?

Background: Diabetes self-care is a key element in the overall management of diabetes. However, the importance of psychosocial factors for successful disease management is under investigated. This study aimed at exploring the role of coping styles and social support in the relationship between self-care activities and glycated haemoglobin in patients with type 2 diabetes.

Methods: One hundred adults (60% female, aged 40–70 years) with type 2 diabetes completed questionnaires assessing self-care activities, coping styles and social support. In addition, a blood test was performed to obtain glycated haemoglobin levels.

Results: Result showed significant relationships of glycated haemoglobin with self-care activities, coping styles and social support. Regression analysis indicated that social support had a moderating role on the relationship between self-care activities and glycated haemoglobin, such that, at very high levels of social support the association, between Self-Care and HbA1c disappears.

Conclusions: Findings indicate that health care providers, within the context of the Iranian social and cultural situation, should pay more attention to psychosocial factors when addressing self-care activities. Delineation of the role of coping styles and social support might be useful for identifying patients in need of particular counselling and support for improving self-care activities and HbA1c levels.
