Exploration in free word association networks: models and experiment

Free association is a task that requires a subject to express the first word to come to their mind when presented with a certain cue. It is a task which can be used to expose the basic mechanisms by which humans connect memories. In this work, we have made use of a publicly available database of free associations to model the exploration of the averaged network of associations using a statistical and the adaptive control of thought–rational (ACT-R) model. We performed, in addition, an online experiment asking participants to navigate the averaged network using their individual preferences for word associations. We have investigated the statistics of word repetitions in this guided association task. We find that the considered models mimic some of the statistical properties, viz the probability of word repetitions, the distance between repetitions and the distribution of association chain lengths, of the experiment, with the ACT-R model showing a particularly good fit to the experimental data for the more intricate properties as, for instance, the ratio of repetitions per length of association chains.     

Young Women’s Experience of Sexuality: A Battle of Pleasure and Sexual Purity in the Context of Malaysian Society

Little is known regarding the ways in which Malaysian women’s sexuality is constructed, and how their personal experiences, culture, religion and society influence their feeling, attitude and sexual behaviours. This study explored the sexual experiences of young adult women in the developing context of the country. A qualitative phenomenological approach was adopted. Purposive sampling was employed, and a total of 20 participants were recruited, comprised of the major ethnic groups in Malaysia. Four main themes emerged through the phenomenological analysis of the data, including: conditional pleasure; social honour and women’s purity; risk and responsibility; and transcendence of love and emotion. The findings of this study revealed that sexuality was experienced under the control of religion and society with the concern of conserving a woman’s purity and social honour; and imposing risks and responsibility on women. Despite the awareness of women’s right to experience sexual pleasure, it was commonly perceived that sexual activities beyond the social norms will result in social shaming and guilt. The authors recommend appropriate sexuality education regarding sexual assertiveness and communication, safe-sex practices, and improving sexual decision-making skills.     

Temperament-Character Profile and Psychopathologies in Patients with Alopecia Areata

The aim of this study is to investigate psychopathologies and the temperament-character profile of Alopecia Areata patients and to compare them with healthy controls. Patients and controls who presented at a dermatology clinic were selected by convenience sampling to respond to Temperament and Character Inventory (TCI), SCL-90-R, and a checklist about the demographic data and their dermatologic and psychiatric history. Patients reported higher harm avoidance and reward dependence than controls (Cohen's d = .93 and = .94). A significant correlation between Harm Avoidance (r = ?0.33, p = .02) and Reward Dependence (r = ?0.28, p = 0.05) with sex was found (females scored higher). Lifetime history of AA relapse was significantly associated with higher psychiatric symptoms; the effect sizes were large for Obsessive-Compulsive (d = .81) and Paranoia Ideation (d = .89). The higher psychological symptoms in AA patients with the history of relapses in this study have a practical message for clinicians.     

World Map of Scientific Misconduct

A comparative world map of scientific misconduct reveals that countries with the most rapid growth in scientific publications also have the highest retraction rate. To avoid polluting the scientific record further, these nations must urgently commit to enforcing research integrity among their academic communities.

Testing a Burnout Model Based on Affective-motivational Factors among EFL Teachers

The purpose of the present study was to explore English as a Foreign Language (EFL) teacher’s motivations for teaching and testing a model of burnout based on motivations and emotions using structural equation modeling (SEM). For this purpose, a total number of 326 Iranian EFL teachers in different language institutes completed the related scales. Results of the study showed that altruistic and intrinsic factors are the main motivations of EFL teachers. Results of SEM indicated that both motivations and emotions predicted different dimensions of burnout. However, emotions had a stronger effect on burnout dimensions than motivational factors. Finally, the pedagogical implications were discussed based on the results of the study.

Views of individuals with gender dysphoria and disorders of sex development on sexism: An Iranian study

ABSTRACT

Background: Ambivalent sexist attitudes have been previously measured regarding several factors such as sex, race and religion.

Aims: In this study, we evaluated the ambivalent sexism among Iranian individuals with gender dysphoria with or without disorders of sex development (DSD).

Methods: Attitudes towards gender stereotypes were investigated using Ambivalent Sexism Inventory (ASI) among three groups of participants with varying psychosexual outcome. These groups were transpeople (N = 152, M = 25.44, SD = 6.52), people with DSD (N = 40, M = 21.2, SD = 2.24) and cisgender people (N = 195, M = 25.9, SD = 5.59).

Results: Significant differences in both types of sexism, benevolent (F (2,383) = 134.217, p < .001) and hostile (F (2,383) = 93.765, p < .001), were found between transpeople, participants with DSD and controls. While scores of transpeople and people with DSD were not significantly different from each other (p = 0.191, Cohen's d = 0.38), both groups were significantly more sexist than controls on hostile sexism (p < 0.001, Cohen's d = 1.4 and 1.1). In benevolent sexism, there were significant differences between the scores of the trans, DSD and control groups, with individuals with DSD being most sexist followed by transgender people (p < 0.001) and controls showing the least degree of sexism (p < 0.001).

Conclusion: Using the Gender Self-Socialization Model (GSSM), we propose that increased scores of ASI among individuals whose gender identity is incongruent with all or some of their physical features are attempts to attain gender typicality. This may lead to a higher degree of sexist beliefs than when all sex and gender characteristics are congruent.     

Error analysis of digital filters using HOL theorem proving

When a digital filter is realized with floating-point or fixed-point arithmetics, errors and constraints due to finite word length are unavoidable. In this paper, we show how these errors can be mechanically analysed using the HOL theorem prover. We first model the ideal real filter specification and the corresponding floating-point and fixed-point implementations as predicates in higher-order logic. We use valuation functions to find the real values of the floating-point and fixed-point filter outputs and define the error as the difference between these values and the corresponding output of the ideal real specification. Fundamental analysis lemmas have been established to derive expressions for the accumulation of roundoff error in parametric Lth-order digital filters, for each of the three canonical forms of realization: direct, parallel, and cascade. The HOL formalization and proofs are found to be in a good agreement with existing theoretical paper-and-pencil counterparts.
