A Calculus of Substitutions for DPL

We consider substitutions in order sensitive situations, having in the back of our minds the case of dynamic predicate logic (DPL) with a stack semantics. We start from the semantic intuition that substitutions are move instructions on stacks: the syntactic operation [y/x] is matched by the instruction to move the value of the y-stack to the x-stack. We can describe these actions in the positive fragment of DPLE. Hence this fragment counts as a logic for DPL-substitutions. We give a calculus for the fragment and prove soundness and completeness.     

Differentiating cognitive content between depressed and anxious outpatients

Quantitative research suggests that depressed and anxious patients can be differentiated based on their cognitive content. This study used qualitative research methods to separate the specific components of open-ended depressive and anxious thought content in 79 psychiatric outpatients. Patients with major depressive disorder (MDD; n = 36), generalized anxiety disorder (GAD; n = 10), and other psychiatric disorders (PC; n = 33) were instructed to (a) describe their most bothersome problem; (b) imagine the worst possible negative outcome followed by the best possible positive outcome; and (c) describe associated thoughts and emotions for each scenario. The content of patients' responses were coded to examine (a) the types and severity of problems; (b) the presence or absence of hopelessness, catastrophizing, hopefulness, and unrealistic positive expectations; and (c) the presence or absence of particular emotions associated with imagined worst and best outcomes. More GAD patients than MDD and PC patients indicated anticipated anxious emotions associated with imagined worst outcomes, and fewer MDD patients than GAD and PC patients indicated anticipated happiness associated with imagined best outcomes. No group differences emerged for the other variables considered. These findings suggest that depressed and anxious patients differ in their cognitive expectancies about future life events in terms of their own anticipated emotional reactions.     

How terrorism news reports increase prejudice against outgroups: A terror management account

Three studies tested predictions derived from terror management theory (TMT) about the effects of terrorism news on prejudice. Exposure to terrorism news should confront receivers with thoughts about their own death, which, in turn, should increase prejudice toward outgroup members. Non-Muslim (Studies 1-3) and Muslim (Study 3) participants were exposed to news about either Islamic terrorist acts or to control news. When Dutch filmmaker Theo van Gogh was murdered in Amsterdam by an Islamic extremist during data collection of Study 1, this event was included as a naturally occurring factor in the design. Consistent with TMT, terrorism news and Van Gogh’s murder increased death-related thoughts. Death-related thoughts, in turn, increased prejudiced attitudes toward outgroup members, especially when participants had low self-esteem, and when terrorism was psychologically close. Terrorism news may inadvertently increase prejudiced attitudes towards outgroups when it reminds viewers of their own mortality.     

Applicability of the Ben-Tovim Walker Body Attitude Questionnaire in Moslem women

There are some valuable questionnaires to assess the body attitude but applicability of those in Moslem women is unknown and the aim of this study was assessment of the validity and reliability of the Iranian-translated versions of the Ben-Tovim Walker Body Attitudes Questionnaire (BAQ) in Iranian women. The BAQ 44 item was administered to 304 healthy non-pregnant Iranian women. A confirmatory factor analysis was carried out. The internal consistency reliability and Inter-correlations of the BAQ subscales and concurrent validity were assessed. The results showed that 9 out of 44 items had insignificant regression weights on the respective factors that further were nominated to deletion. The 6-factor model has an acceptable fit with the data. The internal consistency was .91 for all scale of 35-item BAQ. The coefficient of repeatability (ICC) respectively were .78, .77, .89, .94, .86 and .79 for attractiveness, disparagement, feeling fat, salience of weight/shape, lower body fat and strength and fitness. Results showed that the 6-factor model the 35-item questionnaire is appropriate for evaluating body attitude in Moslem women.     

Cities’ Policies: the Work of European Cities to Counter Muslim Radicalisation

Intercultural relations might form the foundation for new developments and can stimulate energy in modern cities, but in some cases, these relations can also become the source of divergence and conflict. In the last decade, several European cities have been confronted with violent incidents related to some form of extremism. Some cities had to cope with violence by Muslim extremists, for instance Amsterdam, which dealt with the murder of Theo van Gogh. Other cities experienced violence from anti-immigrant or extreme-right movements, for instance London, where mosques were attacked. Radicalisation of small groups of immigrants or autochthonous people, who are distressed about intercultural relations, seemed to lie behind these incidents. Pressured by such events, some administrations in Europe developed policies. In this paper, we will discuss a number of examples of such local policies. We will discuss some programmes that we observed in cities that took part in our own fieldwork, the Cities Local Integration Policies (CLIP) project, which took place from 2007 to 2011.. Our results show that both cities that do have de-radicalisation policies and cities that do not actually work on what phase theorists would call the breeding ground for radicalisation and on the final violent stage of terrorist acts. The difference between the two mainly lies in (not) addressing religious conservatism. We conclude the article with some remarks regarding this choice, also reflecting on the impact of the phase model supported at that time.     

Examining the Impact of Dons Providing Peer Instruction for Academic Integrity: Dons’ and Students’ Perspectives

A peer instruction model was used whereby 78 residence dons (36 males, 42 females) provided instruction regarding academic integrity for 324 students (125 males, 196 females) under their supervision. Quantitative and qualitative analyses were conducted to assess survey responses from both the dons and students regarding presentation content, quality, and learning. Overall, dons consistently identified information-based slides about academic integrity as the most important material for the presentations, indicating that fundamental information was needed. Although student ratings of the usefulness of the presentations were middling, students did indicate knowledge gains. Both interest and personal value for academic integrity were highly predictive of positive evaluations of the presentations. Dons and students provided suggestions for improvement and identified more global concerns.     

The importance of feature distribution and correlation for simulating 3 to 4-month-old infants' visual categorization processes

Mareschal, French, and Quinn (2000) and Mareschal, Quinn, and French (2002) have proposed a connectionist model of visual categorization in 3- to 4-month-old infants that simulates and predicts previously unexplained behavioural effects such as the asymmetric categorization effect (French, Mareschal, Mermillod, & Quinn, 2004). In the current paper, we show that the model's ability to simulate the asymmetry depends on the correlational structure of the stimuli. These results are important given that adults (Anderson & Fincham, 1996) as well as infants (Younger & Cohen, 1986) are able to rely on correlation information to perform visual categorization. At a behavioural level, the current paper suggests that pure bottom-up processes, based on the correlational structure of the categories, could explain the disappearance of the asymmetry in older 10-month-old infants (Furrer & Younger, 2005). Moreover, our results also raise new challenges for visual categorization models that attempt to simulate the shift from asymmetric categorization in 3- to 4-month-old to symmetric categorization in 10-month-old infants (Shultz & Cohen, 2004; Westermann & Mareschal, 2004, 2012).     

Categorical perception of anger is disrupted in alexithymia: Evidence from a visual ERP study

High and low alexithymia scorers were confronted with a modified visual oddball task that allowed the study of categorical perception of emotional expressions on faces. Participants had to quickly detect a deviant (rare) morphed face that shared or did not share the same emotional expression as the frequent one. Expected categorical perception effects, which were also neurophysiologically indexed, showed that rare stimuli were detected faster if they depicted a different emotional expression compared to rare stimuli depicting the same emotional expression than the frequent one. Even if no differences were observed at a behavioural level, high alexithymia scorers evidenced overall delayed neurophysiological responses in components related to the attentional processing of rare emotional faces. Moreover, the categorical perception effects for event-related components associated with the attentional processing were smaller in high alexithymia scorers and were even absent for anger. These results show that high alexithymia scorers present discrimination delays that are already observed at the attentional level.
