Belief Revision And Epistemology

Postulational approaches attempt to understand the dynamics of belief revision by appealing to no more than the set of beliefs held by an agent and the logical relations between them. It is argued there that such an approach cannot work. A proper account of belief revision must also appeal to the arguments supporting beliefs, and recognize that those arguments can be defeasible. If we begin with a mature epistemological theory that accommodates this, it can be seen that the belief revision operators on which the postulational theories are based are ill-defined. It is further argued that there is no way to repair the definitions so as to retain the spirit of those theory. Belief revision is better studied from within an independently motivated epistemological theory.     

Tone sequences with conflicting fundamental pitch and timbre changes are heard differently by musicians and nonmusicians

An Auditory Ambiguity Test (AAT) was taken twice by nonmusicians, musical amateurs, and professional musicians. The AAT comprised different tone pairs, presented in both within-pair orders, in which overtone spectra rising in pitch were associated with missing fundamental frequencies (F0) falling in pitch, and vice versa. The F0 interval ranged from 2 to 9 semitones. The participants were instructed to decide whether the perceived pitch went up or down; no information was provided on the ambiguity of the stimuli. The majority of professionals classified the pitch changes according to F0, even at the smallest interval. By contrast, most nonmusicians classified according to the overtone spectra, except in the case of the largest interval. Amateurs ranged in between. A plausible explanation for the systematic group differences is that musical practice systematically shifted the perceptual focus from spectral toward missing-F0 pitch, although alternative explanations such as different genetic dispositions of musicians and nonmusicians cannot be ruled out.

Direct and Indirect Assessment of Gender Role Identification

Differences in gender role identification exist among both men and women. Earlier researchers have developed several instruments to measure the degree to which individuals identify with the masculine or feminine gender role. In the present study we examined a number of these measurement procedures. Undergraduate students (N?=?45) were administered three direct and two indirect measures of gender role identification. In addition, participants were exposed to a psychological stress test that was relatively masculine. Findings reveal that direct and indirect instruments tap different underlying constructs of gender role identification that are nevertheless positively correlated. Furthermore, results suggest that one of the indirect measures, the Gender Implicit Association Test (GIAT), is a promising instrument to provide an estimate of gender role identification. Of all gender role identification measures the GIAT was (a) most sensitive to sex differences and (b) the only significant predictor of systolic blood pressure responses during and after the relatively masculine stress task.     

Mechanisms and the Evidence Hierarchy

Evidence-based medicine (EBM) makes use of explicit procedures for grading evidence for causal claims. Normally, these procedures categorise evidence of correlation produced by statistical trials as better evidence for a causal claim than evidence of mechanisms produced by other methods. We argue, in contrast, that evidence of mechanisms needs to be viewed as complementary to, rather than inferior to, evidence of correlation. In this paper we first set out the case for treating evidence of mechanisms alongside evidence of correlation in explicit protocols for evaluating evidence. Next we provide case studies which exemplify the ways in which evidence of mechanisms complements evidence of correlation in practice. Finally, we put forward some general considerations as to how the two sorts of evidence can be more closely integrated by EBM.     

Separate or together? Women-only public spaces and participation of Saudi women in the public domain in Saudi Arabia

Gender segregation in the public domain has become a cornerstone of the Saudi interpretation of Islam (Doumato 2009). It is a development that has led to the coming about of extensive separate public spaces that are only for women (Doumato 2009; Hamdan 2005; Le Renard 2008, 2014). In these women-only public spaces, women undertake activities that are by them and for them, therewith reinforcing the existence of these separate structures. This institutionalisation and practice of women-only public spaces, as well as its opposite phenomenon of ‘mixing’ between the two sexes (ikhtilā?) however is contested and led to a heated debate. This debate centres around the question of whether and if so, how women should participate in the public domain. Starting with an overview of the historical development of women-only public spaces and ikhtilā? in Saudi Arabia, I will show how these have evolved. Drawing on fieldwork among urban, educated Saudi women, I shed light on how attitudes and strategies of female respondents regarding women-only public spaces and ikhtilā? are related to their ideas about their presence in the public domain and notions of ‘the liberation of women’, ‘empowerment’, and ‘the rise of women’. I conclude by demonstrating how ideas about the participation of women in the public sphere are positioned as part of the construction of a local, ‘enchanted’ modernity (Deeb, 2006) that has a material and a spiritual dimension.     

Loss,Grief, and the Search for Significance: Toward a Model of Meaning Reconstruction in Bereavement

Constructivist theories recently have begun to inform understandings of grief, emphasizing the role of meaning making in adaptation to bereavement. In this article we review empirical studies using qualitative, quantitative, and mixed methods, investigating how three activities of meaning reconstruction are involved in the grieving process: sense making, benefit finding, and identity change. In particular, we consider how critical processes have been operationally defined and how study methods and designs have constrained what can be concluded from this burgeoning field of research. We conclude by positing an integrated model of meaning reconstruction pathways as a heuristic guide to further research and briefly note the implications of this model for clinical practice.     

Cognitive-Behavioral Therapy for Prolonged Grief in Children: Feasibility and Multiple Baseline Study

There is growing recognition of a syndrome of disturbed grief referred to as prolonged grief disorder (PGD). Although mostly studied in adults, clinically significant PGD symptoms have also been observed in children and adolescents. To date, no effective treatment for childhood PGD yet exists. We developed a 9-session cognitive-behavioral treatment for childhood PGD, combined with 5 sessions of parental counseling. In the present article, the content of this treatment is described. We also describe findings of a multiple baseline study among 6 bereaved children and adolescents. This study showed that the intervention coincided with reductions in symptoms of PGD and other self-rated and parent-rated symptoms. All participating children and parents gave favorable scores to the satisfaction about each session, the contact with their therapist, and the information they received, attesting to the feasibility of this treatment approach.     

A study of the discrepancy between self- and observer-ratings on managerial derailment characteristics of European managers

Managerial derailment is costly to managers, their co-workers, and their organization. Knowing whether discrepancies (i.e., differences, dissimilarity, disagreement, incongruity) exist between self- and observer- (subordinates, peers, and bosses) ratings about derailment may help to lessen or prevent the detrimental outcomes of derailment on managers, their co-workers, and their organization. Results from 1742 European managers revealed a statistically significant difference between a manager's self-ratings and observer-ratings on the extent to which a manager displayed derailment behaviours and characteristics. The discrepancy also widened as managerial level increased, and was mostly due to inflated self-ratings. In addition, discrepancies between self – boss, self – direct report, and self – peer were examined, as well as differences between European and American managers. A discussion of these findings and implications for practice conclude this article.     

Charting the Attributes of God: The Common Ground of Three Religions according to Ramon Llull (1232–1316)

The Open Letter written by 138 major representatives of Islam to the leaders of the Christian churches, on 13 October 2007, came as something of a surprise. Perhaps more surprisingly, in 1283, the Catalan theologian, Ramon Llull, wrote imaginatively of exactly such a letter in one of his novels, thus demonstrating that the interfaith question is not just a problem of our modern times, which became acute only on September 11. On the contrary, the churches have always been conscious of this interfaith context. Yet methods of tackling the problem have differed widely down the centuries and among Christian traditions. The solution proposed by Ramon Llull and analysed in this article starts from the common acceptance of the attributes of God in all three monotheistic religions. It deserves our attention not only as an interesting historical example but also as a way of avoiding some of our current problems and impasses.
