Demonstration and interpretation of ‘scutoid’ cells formed in a quasi-2D soap froth

ABSTRACT

Recently a novel type of epithelial cell has been discovered and dubbed the ‘scutoid’. It is induced by curvature of the bounding surfaces. We show by simulations and experiments that such cells are to be found in a dry foam subjected to this boundary condition.     

Some Evidence is False

According to some philosophers who accept a propositional conception of evidence, someone's evidence includes a proposition only if it is true. I argue against this thesis by appealing to the possibility of knowledge from falsehood.     

Toward a Reconstruction of Medical Morality

At the center of medical morality is the healing relationship. It is defined by three phenomena: the fact of illness, the act of profession, and the act of medicine. The first puts the patient in a vulnerable and dependent position; it results in an unequal relationship. The second implies a promise to help. The third involves those actions that will lead to a medically competent healing decision. But it must also be good for the patient in the fullest possible sense. The physician cannot fully heal without giving the patient an understanding of alternatives such that he or she can freely arrive—together with the physician—at a decision in keeping with his or her personal morality and values. In today's pluralistic society, universal agreement on moral issues between physicians and patients is no longer possible. Nevertheless, a reconstruction of professional ethics based on a new appreciation of what makes for a true healing relationship between patient and physician is both possible and necessary.     

Fear response to dissociation challenge

Abstract

Participants (N = 101) scoring high or low on a new scale for assessing fear of dissociative sensations (Dissociation Sensitivity Index) underwent an audio/visual sensory challenge using a device called the D.A.V.I.D. Participants' report of subjective fear and level of dissociation were measured before and after completing the audio/visual sensory challenge. Consistent with prediction, participants scoring high on the DSI responded to the challenge with significantly greater increases in subjective fear and dissociative symptoms relative to those scoring low on the DSI. Contrary to prediction, the DSI performed poorer than the Anxiety Sensitivity Index in predicting participants' response to the audio/visual sensory challenge. Theoretical and clinical implications of the findings are discussed.     

Therapeutic Implications of Religious-Related Emotional Abuse

Religion can play a positive role in preventing all types of abuse. Consequently, it is often difficult to believe that religion or a particular manner of religious awareness can also be conducive to the degradation and humiliation of individuals, and that it can be maneuvered to justify abusive behavior. In this article we discuss the emotional repercussions of religious-related abuse in the family, an aspect that is rarely documented in the field of psychotherapy, but has many negative consequences. Religious-oriented emotional abuse is traceable to several levels of human functioning: the individual's internal level of experiencing themselves, the interpersonal and systemic levels, where the individual enters relationships, as well as within the framework of the individual's relationship with God.     

Effects of membership change on open discussion and team performance: The moderating role of team tenure

This study identified temporal conditions when membership change may enhance or diminish team functioning. Using a longitudinal repeated measures design surveying 41 R&D teams, this study examined whether team tenure moderated the relationship of membership change with open discussion and team performance. The results illustrated that increasing membership change was positively associated with both open discussion and team performance for newly formed teams, whereas this association was negative for long-serving teams. Thus, what matters is not so much whether a team's membership changes but rather whether the team's longevity supports or impedes adaptation to personnel changes.     

Associations between rating content and self-other agreement in multi-source feedback

In a study of the ratings of managers' behaviour made by themselves, their supervisors, subordinates, and peers, it was found that degree of similarity between self-ratings and ratings by colleagues was significantly associated with three aspects of rating content: the observability of a behaviour, its desirability, and the degree to which it concerned technical rather than interpersonal activities. However, these associations with rating content depended on which of two indices of between-rater similarity was studied, in terms of either the correlation or the difference between ratings. The desirability of behaviour more influenced correlation measures of similarity, and the type of behaviour had more influence on difference scores: managers over-rated their interpersonal activities but not their technical effectiveness.     

Distancing oneself from God: relationships with borderline personality symptomatology

Self-harm behaviour traditionally has been associated with borderline personality disorder. In this study, we examined the relationship between borderline personality symptomatology and intentionally distancing oneself from God as self-punishment, based on the assumption that such self-punishment may represent a form of self-harm behaviour. Data from four previous samples of primary care outpatients collected over a two-year period were combined (N?=?1511). Borderline personality was assessed with two measures: the borderline personality scale of the Personality Diagnostic Questionnaire-4 (PDQ-4) and the Self-Harm Inventory (SHI). Point-biserial correlation coefficients revealed that those who endorsed distancing oneself from God as punishment scored relatively higher on both the PDQ-4 (r?=?0.40, p?<?0.001) and the SHI (r?=?0.46, p?<?0.001). Similarly, when compared to respondents who denied ever having distanced themselves from God as punishment, those who did were more likely to exceed the clinical cut-off score on the PDQ-4 (47.3% vs. 10.9%, X^{2 ?}=?152.53, p?<?0.001) and the SHI (57.3% vs. 11.4%, X^{2 ?}=?224.12, p?<?0.001). Findings support our hypothesis that distancing oneself from God as punishment may be a form of self-harm behaviour associated with borderline personality symptomatology.     

Mediated conditioning versus retrospective revaluation in humans: The influence of physical and functional similarity of cues

Two experiments assessed whether similarity between the two elements of a compound would influence the degree of mediated extinction versus recovery from overshadowing in human causal judgements. In both Experiments 1 and 2, we assessed the influence of extinguishing one element of a two-element compound on judgements about the other element. In Experiment 1 we manipulated the physical similarity of the two elements of the compound; in Experiment 2, we used equivalence and distinctiveness pretraining in order to vary their functional similarity. We found that these procedures influenced mediated extinction and recovery from overshadowing as a function of both physical and acquired similarity and distinctiveness, respectively. The implications of these results for previously reported differences between humans and nonprimate animals are discussed.
