Associations between schizotypy and belief in conspiracist ideation

Previous studies have reported associations between conspiracist ideation and domain-level facets of schizotypy, but less is known about associations with lower-order facets. In the present study, 447 adults completed measures of conspiracist ideation and the Schizotypal Personality Questionnaire (SPQ), consisting of nine subscales grouped into four domains. Results of a multiple regression showed that two domains of the SPQ significantly predicted conspiracist ideation, but multicollinearity was a limiting factor. In a second regression, we found that the subscales of Odd Beliefs or Magical Thinking and Ideas of Reference significantly predicted conspiracist ideation, without any multicollinearity constraints. We interpret these results as implicating two specific lower-order facets of schizotypy in belief in conspiracy theories. We further contrast the present results with previous studies indicating associations between conspiracist ideation and paranormal beliefs.

Associations between Belief in Conspiracy Theories and the Maladaptive Personality Traits of the Personality Inventory for DSM-5

Conspiracy theories can be treated as both rational narratives of the world as well as outcomes of underlying maladaptive traits. Here, we examined associations between belief in conspiracy theories and individual differences in personality disorders. An Internet-based sample (N=259) completed measures of belief in conspiracy theories and the 25 facets of the Personality Inventory for DSM-5 (PID-5). Preliminary analyses showed no significant differences in belief in conspiracy theories across participant sex, ethnicity, and education. Regression analyses showed that the PID-5 facets of Unusual Beliefs and Experiences and, to a lesser extent, Suspiciousness, significantly predicted belief in conspiracy theories. These findings highlight a role for maladaptive personality traits in understanding belief in conspiracy theories, but require further investigation.

Cues to action : do they result in belief and behavioural change in women?

With incidence rates of osteoporosis increasing (Osteoporosis Canada, 2007), preventative efforts to minimize costs associated with condition diagnosis are a public health priority. Cues to action are specific internal (e.g., physical symptoms, family member with a condition) or external stimuli (e.g., public service announcements, health education campaigns) that are necessary to trigger appropriate health behaviours and serve to create an awareness of the health threat (Mattson, 1999). To date, limited understanding of the scope of influence cues to action have on health beliefs and behaviour associated with osteoporosis is known. The present investigation was designed to address this gap in the literature. More specifically, the influence of cues to action, a public service announcement (PSA) developed by Osteoporosis Canada and a bone screening by way of Quantitative Ultrasound, on health beliefs and health-enhancing physical activity (HEPA) across a four week period was investigated. Peri-and postmenopausal women (N= 174) were randomly assigned to one of three conditions 1) an osteoporosis public service announcement (PSA) condition; 2) a bone screening condition via quantitative ultrasound techniques, and 3) a PSA attention control condition. Health beliefs associated with osteoporosis were taken at three time points: prior to the cue to action intervention, immediately following the intervention, and four weeks post intervention. Knowledge of osteorporosis risk factors and HEP A were assessed pre and post-intervention only. Results of a regression analysis suggested that baseline health beliefs predicted baseline HEPA (R2 adj = .24; F (9, 161) = 6.49,p = .000; 95% CI = .12 - .35) with exercise barriers (p = -.33) being a negative predictor and health motivation (p = .21) being a positive predictor of HEP A.

Believing in belief : the modernist quest for spiritual meaning (Croyer en croyance : la quête moderniste pour le sens spirituel)

Cette thèse défend l’idée que plusieurs auteurs modernistes ont utilisé des concepts centraux à la croyance religieuse traditionnelle afin de préconiser le changement social. Au lieu de soutenir l'hypothèse de la sécularisation, qui prétend que les modernistes ont rejeté la religion en faveur d'une laïcité non contestée, j'argumente en faveur de ce que j'appelle « la spiritualité moderniste, » qui décrie une continuité intégrale des concepts spirituels dans l'agitation de la période moderniste qui a déstabilisée les institutions qui avait auparavant jeté les bases de la société Occidentale. En me basant sur les écrit de Sigmund Freud, William James et Émile Durkheim concernant les fins poursuivis par la religion, je développe cinq concepts centraux de la croyance religieuse que les modernistes ont cherché à resignifier, à savoir la rédemption, la communauté, la sacralité, le spectre, et la liturgie, et, dans chaque cas, j'ai montré comment ces catégories ont été réinterprétées pour traiter des questions considérées comme essentielles au début du vingtième siècle, à savoir ce que l’on identifie aujourd’hui comme le féminisme, l'écologie, la biopolitique, les crises, et le rôle du poète. Le chapitre I se concentre sur la rédemption par le féminin telle qu’on la trouve dans le recueil de vers de H.D. portant sur la Seconde Guerre mondiale, Trilogy (1944-1946), qui projette un certain espoir grâce à un mélange synchrétique de Christianisme, de mythes anciens, d’astrologie, et de psychologie. Mon deuxième chapitre discute de The Grapes of Wrath (1939) de John Steinbeck, qui élargit le rôle de la communauté en avançant une écologie universelle qui concevoit tous les gens comme étant intimement liés entre eux et avec le monde. Le chapitre III traite de la notion du sacré dans The Light in August (1932) de Willam Faulkner et Nightwood (1936) de Djuna Barnes, qui préconisent une foi privatisée qui accentue l'illégitimité des concepts de sacralité et de pollution en élevant des individus qui sont marginalisés biopolitiquement. Le chapitre IV cherche à comprendre le retour des morts, et je soutiens que le topos a été utilisé par les modernistes comme un symbole de crises sociales; le chapitre enquête d'abord sur “The Jolly Corner” (1908) de Henry James, que j'ai lu comme la séquence rêvée d'un homme faisant face à son propre spectre, Ulysses (1922) de James Joyce, où Stephen Dedalus est hanté de façon répétée par le spectre de sa mère, et Mrs. Dalloway (1925) de Virginia Woolf, qui se concentre sur le motif caché de la Fête des Morts. Ma cinquième section traite de la liturgie, la langue poétique utilisée pour les rites religieux, dans la première poésie de Wallace Stevens, qui conçoit le rôle du poète comme une vocation de l'imagination.

Fast Learning by Bounding Likelihoods in Sigmoid Type Belief Networks

Sigmoid type belief networks, a class of probabilistic neural networks, provide a natural framework for compactly representing probabilistic information in a variety of unsupervised and supervised learning problems. Often the parameters used in these networks need to be learned from examples. Unfortunately, estimating the parameters via exact probabilistic calculations (i.e, the EM-algorithm) is intractable even for networks with fairly small numbers of hidden units. We propose to avoid the infeasibility of the E step by bounding likelihoods instead of computing them exactly. We introduce extended and complementary representations for these networks and show that the estimation of the network parameters can be made fast (reduced to quadratic optimization) by performing the estimation in either of the alternative domains. The complementary networks can be used for continuous density estimation as well.

Belief Propagation and Revision in Networks with Loops

Local belief propagation rules of the sort proposed by Pearl(1988) are guaranteed to converge to the optimal beliefs for singly connected networks. Recently, a number of researchers have empirically demonstrated good performance of these same algorithms on networks with loops, but a theoretical understanding of this performance has yet to be achieved. Here we lay the foundation for an understanding of belief propagation in networks with loops. For networks with a single loop, we derive ananalytical relationship between the steady state beliefs in the loopy network and the true posterior probability. Using this relationship we show a category of networks for which the MAP estimate obtained by belief update and by belief revision can be proven to be optimal (although the beliefs will be incorrect). We show how nodes can use local information in the messages they receive in order to correct the steady state beliefs. Furthermore we prove that for all networks with a single loop, the MAP estimate obtained by belief revisionat convergence is guaranteed to give the globally optimal sequence of states. The result is independent of the length of the cycle and the size of the statespace. For networks with multiple loops, we introduce the concept of a "balanced network" and show simulati.

Miniature Carvings in the Canadian Dorset Culture: the Paleo-Eskimo Belief System

En este estudio, intento resumir los debates relacionados con la última cultura paleoesquimal de Canadá Ártica y la de Groenlandia, y llamar la atención sobre las analogías culturales desde Asia, además de crear un cuadro complejo sobre el chamanismo y el culto al oso de los Dorset. Los temas como el origen del arte de los Dorset, la transición Pre-Dorset-Dorset, y los contactos entre los Dorset y los Thule son relevantes para reconstruir el sistema de creencias de los Dorset. Sin embargo, la totalidad del sistema de creencias de los paleoesquimales no se puede comprender sobre la base de los hallazgos arqueológicosy las analogías etnográficas remotas.

Preliminary factorial structure of the O’Kelly Women’s Belief Scales in Mexican population

A Back-translated Mexican version of the Austra- lian o’Kelly Women’s Belief scales was given to a sample of 363 women born and living in Mexico. A factor analysis with a varimax rotation with cu- toff eigenvalues of 3 showed that 36 out of the 92 items originally developed in the Australian study accounted for 40.138% of the variance, and could be ultimately grouped into two factors: one “ra- tionality” factor, with a total of 14 items, and one “Irrationality” factor with a total of 22 items, and with a very low Pearson’s rs (.119) between them. these results support the equivalency of the Mexi- can version to the original instrument used to iden- tify the presence of the reBt’s absolutistic, rigid beliefs about traditional feminine roles in women.

Modeling the user knowledge by belief networks

This paper describes the user modeling component of EPIAIM, a consultation system for data analysis in epidemiology. The component is aimed at representing knowledge of concepts in the domain, so that their explanations can be adapted to user needs. The first part of the paper describes two studies aimed at analysing user requirements. The first one is a questionnaire study which examines the respondents' familiarity with concepts. The second one is an analysis of concept descriptions in textbooks and from expert epidemiologists, which examines how discourse strategies are tailored to the level of experience of the expected audience. The second part of the paper describes how the results of these studies have been used to design the user modeling component of EPIAIM. This module works in a two-step approach. In the first step, a few trigger questions allow the activation of a stereotype that includes a "body" and an "inference component". The body is the representation of the body of knowledge that a class of users is expected to know, along with the probability that the knowledge is known. In the inference component, the learning process of concepts is represented as a belief network. Hence, in the second step the belief network is used to refine the initial default information in the stereotype's body. This is done by asking a few questions on those concepts where it is uncertain whether or not they are known to the user, and propagating this new evidence to revise the whole situation. The system has been implemented on a workstation under UNIX. An example of functioning is presented, and advantages and limitations of the approach are discussed.

Beyond Belief: Harry Potter in text and film

Despite the fact that the Harry Potter books have won a place in the cultural consciousness and have had enjoyed immense commercial success, they were not accepted within many faith groups at the outset. Using the term ‘religion’ to refers to any system of belief that may be recognised by symbols , I look extracts from three of the novels, alongside their subsequent cinematic adaptations, in order to consider the construction of representations of religion in the films and the contribution made by the films to this debate.

Uptake pathways: the potential of Bayesian belief networks to assist the management, monitoring and evaluation of development-orientated research

The effectiveness of development assistance has come under renewed scrutiny in recent years. In an era of growing economic liberalisation, research organisations are increasingly being asked to account for the use of public funds by demonstrating achievements. However, in the natural resources (NR) research field, conventional economic assessment techniques have focused on quantifying the impact achieved rather understanding the process that delivered it. As a result, they provide limited guidance for planners and researchers charged with selecting and implementing future research. In response, “pathways” or logic models have attracted increased interest in recent years as a remedy to this shortcoming. However, as commonly applied these suffer from two key limitations in their ability to incorporate risk and assess variance from plan. The paper reports the results of a case study that used a Bayesian belief network approach to address these limitations and outlines its potential value as a tool to assist the planning, monitoring and evaluation of development-orientated research.
