The impact of religious cognitive behavioural therapy (RCBT) on general health among Iranians

The aim of this study was to determine the efficacy of religious cognitive behavioural therapy (RCBT) on general health among Iranians. This study was a randomised, single-blinded clinical trial from April 2017 to October 2017. One hundred forty-four Yazd citizens were selected using a cluster sampling method and randomly assigned to experimental or control groups. The experimental groups received 10 sessions of RCBT, lasting 45 minutes once a week and the control group remained on the waiting list. The results showed that mean general health scores in the experimental groups were significantly lower than those in the control group on the post-test. RCBT had the most positive impact on somatic symptoms, anxiety/insomnia, social dysfunction, depression, and mental health. Based on these findings RCBT can be considered a significant and effective practical therapy for improving both general and psychological health.     

Orientation-selective adaptation during motion-induced blindness

When a global moving pattern is superimposed on high-contrast stationary or slowly moving stimuli, the latter occasionally disappear for periods of several seconds (motion-induced blindness, MIB). Here, an adaptation paradigm was used to determine if orientation-selective adaptation still occurs for the stimulus that is no longer visible. Two slowly drifting high-contrast Gabor patches were presented to observers. As soon as both patches disappeared, one was eliminated from the screen. After 2 s, two low-contrast Gabor patches were presented as tests at the same locations and observers were asked to report their orientations. The observers' performance was significantly higher when the orientation of the low-contrast test patch was orthogonal to the orientation of the high-contrast adapting patch (p < 0.0001) for the location where the patch was present during MIB, even though it was perceptually invisible. The observers' performance was not significantly different at the adjacent control location where the stimulus was absent during the MIB. Although no stimulus was visible at either location, orientation-selective adaptation was preserved only for the location at which the patch remained present. Since orientation information is processed in low-level visual areas such as the primary visual cortex (V1), we conclude that MIB originates in an area higher than V1.     

Motion-induced overestimation of the number of items in a display

Subjects were asked to report the number of items in a display as the items moved along a circular path around the fixation point. As the rotation speed increased, the apparent number of items also increased. This motion-induced overestimation (MIO) effect was investigated in three experiments. In the first experiment, the effect of rotation speed and set size was explored with an enumeration task. The overestimation error increased with an increase in speed or number of items in the display. In the second experiment, we used an adjustment paradigm to measure the speed threshold of MIO effect onset. Temporal rate of the display, which was defined as product of rotation speed and the number of rotating items, was the determining factor of MIO onset. In the third experiment, moving items were marked with different colours. Surprisingly, the number of perceived items was still overestimated even though the number of perceived colours was not.     

Are Religious Coping and Pain Perception Related Together? Assessment in Iranian Cancer Patients

Pain of cancer had various significant side effects that based on the literature it can reduced by religious coping methods. This study aimed to investigate the relationship between religious coping and pain perception in Iranian cancer patients. In this cross-sectional study (October–December, 2015), 380 hospitalized cancer patients were entered to the study using accessible sampling. Data were collected by socio-demographic, Religious Coping and McGill pain questionnaires. Males (48.39 ± 13 ± 39; CI95: 46.41–50.38) are older than females (45.33 ± 18.44; CI95: 42.79–47.87). According to results, there was a significant relationship between pain perception and positive religious coping in cancer patients. Also there was a significant relationship between pain perception and family history of cancer (P < 0.05). It seems that improving the level and quality of positive religious affiliation can be effective on the amount of stimulation and pain of cancer patients. Of course, more comprehensive studies are needed to be achieved more reliable results about the effects of religious coping on pain perception in these patients.     

Morphological Development in the Speech of a Persian–English Bilingual Child

The present study aims at testing the two dominant hypotheses regarding the development of inflections and other functional categories namely the Structure-Building Model and the Continuity Hypothesis within the generative theory. According to the first view, functional categories are entirely absent in children’s early grammars, which contain only projections of lexical categories, most importantly ‘nouns’ and ‘verbs.’ This hypothesis holds that utterances produced by children are actually small clauses or verb phrases, and functional categories such as copula, determiners, and genitive are not acquired during the single-word or early multiword stages, but are implemented in the course of further acquisition, at around age 2 or later. The proponents of the second, i.e., the ‘Continuity Hypothesis,’ on the other hand, argue that functional categories are in fact present in children’s early syntax. These two hypotheses will be tested here against empirical data in English and Persian. Thus, longitudinal data will be provided on the acquisition of a few morphemes in the two languages acquired by the subject of the present study (i.e., English and Persian) including determiners, plural marker, genitive, and copula. The significance of the present study lies in the fact that it provides data on two typologically different languages in bilingual first language acquisition and thereby making a contribution to the field.     

Knowledge, Attitudes and Behavioral Intentions of Agricultural Professionals Toward Genetically Modified (GM) Foods: A Case Study in Southwest Iran

While there has been a number of consumers’ studies looking at factors that influence individuals’ attitudes and behavior toward GM foods, few studies have considered agricultural professionals’ intentions in this regard. This study illuminates agricultural professionals’ insights toward GM foods in Southwest Iran. A random sample of 262 respondents was studied. The results indicated that the majority of the respondents had little knowledge about GM foods. They perceived few benefits or risks of GM foods. Their perceived benefits and trust in individuals and institutions had positive impacts on the behavioral intentions of the agricultural professionals. The results also revealed that the low knowledge level of the respondents had a negative impact on the behavioral intentions toward GM foods. This state of affairs is problematic, either GM foods have serious problems or the knowledge conveyed to the Iranian agricultural experts is inappropriate. We recommend a well defined communication strategy to provide information in such a way that allows individuals to feel adequately informed about GM foods. Furthermore, the development of trust and knowledge regarding GM foods can be greater when risk analysis frameworks are transparent, risk assessment methodologies are objective, all stakeholders are engaged in the risk management process, and risk communication focuses on consumers.     

Self-regulated learning: the role of environmental perceptions and motivational beliefs

To examine the correlations among environmental perceptions, motivational beliefs, and self-regulated learning of Tehran third-year high school boys based on a proposed model, multistage cluster-sampling method gave a sample of 685 students. The Motivated Strategies for Learning Questionnaire (Pintrich & De Groot, 1990), Students' Achievement Goal Orientations (Midgley, Kaplan, Middleton, Maehr, Urdan, Anderman, et al., 1998), Students' Perceptions of Classroom Activities (Gentry, Gable, & Rizza, 2002), and Perceptions of Parents Scales (Grolnick, Deci, & Ryan, 1997) were administered. Analysis showed relations among components of self-regulated learning, family environmental perceptions, perceptions of classroom activities, and motivational beliefs. Structural equation modeling indicated the proposed model had an acceptable fit to the data. All paths or structural coefficients of the proposed model were statistically significant.     

Deformation twinning-mediated pseudoelasticity in metal–graphene nanolayered membrane

In this study, we investigated the deformation behaviour of metal–graphene nanolayered composites for five face-centred cubic metals under compression using molecular dynamics simulations. It was found that by increasing the thickness of the individual metal layers, the composite strength increased, while the deformation mechanism changed from buckling to deformation twining in Cu, Au and Ag, which was absent in the monolithic form of those metals of the same orientation and size. The deformation twinning was found to be enabled by the graphene layer, which introduced pseudoelasticity and shape memory effects in the nanolayered membrane with more than 15% recoverable compressive strain.
