Validity of the multiple-stimulus without replacement preference assessment for edible items

Studies have shown that the multiple-stimulus without replacement (MSWO) preference assessment is an effective assessment format for identifying preferred items. However, it is possible that factors other than reinforcer quality might influence selections by some individuals when the MSWO array consists of edible items. The validity of the MSWO results was evaluated by comparing items identified as most and least preferred by the MSWO assessment in a concurrent-schedule (CS) format. Varying edible items were used in each study. The MSWO format accurately identified the higher quality edible item for most participants across studies (76%); however, the MSWO format did not predict the highest quality edible item in the CS assessment for 20% to 30% of participants in each study.     

Same-sex unions in Islam

The objective of this paper was to streamline the case for Muslim same-sex unions that was comprehensively made in Jahangir and Abdullatif (2016). Additionally, we try to address same-sex unions on the basis of non-binary gender, gender expression and sexual orientation. Based on our work, we argue that the case for Muslim same-sex unions can be made on the basis of broad principles of human dignity and affection and therefore through marriage or through the specific arguments of repelling harm and legal authority. In this regard, going beyond the overarching Islamic value of human dignity, we specifically argue that the case for same-sex unions can be anchored on verse 4:28 on facilitating a legal outlet for sexual expression.     

The social and emotional skills of bullies,victims, and bully–victims of Egyptian primary school children

This study examined whether bullies, victims, bully–victims (who are both bullies and victims), and students who reported no or low levels of bullying and victimization differed in their levels of social and emotional skills. Data were collected from 623 children in fifth and sixth grades from four Egyptian elementary schools; their ages ranged from 10 to 12 years. K‐means cluster analysis revealed four groups: bullies (n = 138), victims (n = 178), bully–victims (n = 59), and children who were not involved in bullying behaviour (n = 248). Data were analyzed using multinomial logistic regression. The findings indicated that boys were more involved in bullying behaviour than girls, and both bullies and bully–victims were less likely to adhere to social rules and politeness than children who were not involved in bullying. Both bullies and victims were less aware of the physiological reactions of their emotions than uninvolved children, and were less able to apply social rules in social interaction. Both victims and bully–victims reported less likeability than children not involved in bullying. Verbal sharing, attending to others’ emotions, and analysis of emotions did not have a statistically significant relationship with the probabilities of classifying children to any bullying group versus children not involved in bullying. Social skills were more important than emotional awareness in predicting the likelihood of classifying children in one of the three bullying groups versus children who not involved in bullying. The main conclusion is that social and emotional skills together may provide an effective means of intervention for bullying problems.

The Sudan Experience

This article featuring Sudan constitutes one of five articles in a collection of essays on local capacity-building in research ethics by graduates from the University of Toronto’s Joint Centre for Bioethics MHSc in Bioethics, International Stream programme funded by the Fogarty International Center for Advanced Study in the Health Sciences (FIC). Research ethics is a relatively new area of practice in Sudan. In 2008, the National Health Research Council (NHRC) and health research ethics were clearly stated in the Public Health Act, marking the first legislation rendering research misconduct as a legal offense. It also clearly stated that the NHRC is the focal body of health research in Sudan. Despite the difficulty in following the pace of newly-formed institutions and academies in Sudan, the NHRC’s Research Directorate assisted in the establishment of eight Research Ethics Committees (RECs) in two state ministries of health, two federal hospitals, the Sudan Medical Specialization Board (SMSB), and three universities.     

Challenging the myth of the happy celibate: Muslim women negotiating contemporary relationships

In recent decades, the age of marriage in many minority Muslim communities has risen so that significant numbers of Muslims in these contexts are remaining unmarried into their late 20 s and beyond. As with other communities in Western contexts, Muslim communities have also experienced a rising divorce rate, leading to many more single women. These social and demographic changes, combined with traditional attitudes towards female sexuality and virginity, have led to a rise in the number of women who have either never had a sexual encounter or who no longer have sexual encounters. Cultural discourses surrounding virginity and female celibacy frequently conflate the virtue of refusing sexual encounters outside of marriage with happiness and satisfaction at ‘choosing the right path’. However, these discourses negate or downplay women’s sexual desires and result in women often feeling trapped into having to perform the ‘myth of the happy celibate’. To disrupt this myth is to unleash the potentially destructive power of female sexuality, while to openly challenge it is to risk being positioned as a ‘slut’.

A Comparison of Written,Vocal, and Video Feedback When Training Teachers

We compared the effectiveness of and preference for different feedback strategies when training six special education teachers during a 5-day summer training program. In Experiment 1, teachers received written or vocal feedback while learning to implement two different types of preference assessments. In Experiment 2, we compared either written or vocal feedback to vocal feedback combined with video replays of performance while training the teachers to implement two variations of discrete-trial training. The different forms of feedback were similarly effective for all of the participants. However, all of the teachers showed a preference for vocal feedback when they could choose which form of feedback they would receive from the experimenter. Results have important implications for the use of feedback when training teachers.     

Proprioceptive impairment and postural orientation control in Parkinson's disease

Impairment of postural control is a common consequence of Parkinson’s disease (PD). Increasing evidences demonstrate that the pathophysiology of postural disorders in PD includes deficits in proprioceptive processing and integration. However, the nature of these deficits has not been thoroughly examined. We propose to establish a link between proprioceptive impairments and postural deficits in PD using two different experimental approaches manipulating proprioceptive information. In the first one, the subjects stood on a platform that tilted slowly with oscillatory angular movements in the frontal or sagittal planes. The amplitude and frequency of these movements were kept below the semicircular canal perception threshold. Subjects were asked to maintain vertical body posture with and without vision. The orientations of body segments were analyzed. In the second one, the postural control was tested using the tendon-vibration method, which is known to generate illusory movement sensations and postural reactions. Vibrations were applied to ankle muscles. The subject’s whole-body motor responses were analyzed from center of pressure displacements.In the first experiment, the parkinsonian patients (PP) were unable to maintain the vertical trunk orientation without vision. Their performances with vision improved, without fully reaching the level of control subjects (CS). In the second experiment, the postural reactions of the PP were similar to those of the CS at the beginning of the perturbation and increased drastically at the end of the perturbation’s period as compared to those of CS and could induce fall.These results will bring new concepts to the sensorimotor postural control, to the physiopathology of posture, equilibrium and falls in PD and to the role of basal ganglia pathways in proprioception integration. Nevertheless, in order to assess precisely the role played by sensorimotor integration deficits in postural impairments in PD, further studies establishing the links between clinical features and abnormalities are now required.
