Social problem‐solving,perceived stress,depression and life‐satisfaction in patients suffering from tension type and migraine headaches

This study aimed at investigating social problem solving, perceived stress, depression, and life‐satisfaction in patients with tension type and migraine headaches. Forty‐nine migraine and 42 tension type headache patients (n = 91) consenting to participate were compared to a total of 49 matched healthy control group. Participants filled in a questionnaire consisting self‐report measures of problem solving, perceived stress, depression and life satisfaction. They were also asked about headache duration, frequency, pain severity, psychiatric treatment and sense of control in one's life. T‐tests, chi‐square, analysis of variance, logistic regression analysis and Pearson product moment correlation coefficient procedures were used to analyze the data. Tension type headache patients reported having had more frequent headaches than the migraine patients but migraine patients reported having had more intense pain than the tension type headache patients. Instances of psychiatric treatment were more common among tension type headache patients than the migraine and the control group. Compared to the healthy controls, headache patients displayed a deficiency in problem solving, higher levels of perceived stress and depression. Levels of problem solving skills in headache patients were related inversely to depression, perceived stress and the number of negative life events but problem solving skills of headache patients was related positively to life‐satisfaction. The findings from this study suggested that cognitive behavioral problem solving therapy or training might be a viable option for reducing levels of stress and depression, and to increase life‐satisfaction in patients suffering from primary headache.     

Morphological units in the Arabic mental lexicon: evidence from an individual with deep dyslexia

An ongoing debate in Arabic morphology concerns the nature of the smallest unit governing lexical organization and representation in this language. A standard model maintains that Arabic words are typically analyzable into a three-consonantal root morpheme carrying the core meaning of words and a prosodic template responsible mostly for grammatical information. This view has been largely supported by research in both theoretical linguistics and psycholinguistics. An alternative theory holds that the meaning of words in Arabic is, rather, encoded in the 'etymon' comprising two unordered consonants of the root only. Results from a recent priming experiment have shown that the etymon induces strong morphological priming effects, supporting its morphological/lexical status. In this paper we present data from a patient with deep dyslexia questioning the role of the etymon as a psychologically real representational unit in Arabic and arguing, instead, for the central role of the root in both morphological and lexical representation in this language.     

Suicides in the developing world: case study from Pakistan

There are no official data on suicide from Pakistan, a conservative South Asian Islamic country with traditionally low suicide rates. Both suicide and attempted suicide are illegal acts, as well as socially and religiously condemned, making research in this area difficult. Recent reports suggest an increase in suicide rates. In this study, police data from the Sindh province were examined to provide a unique picture of trends of suicide over 15 years (1985-1999). During this period there were 2,568 reported suicides (71% men, 39% women; ratio 1.8). The lowest number was 90 in 1987 and maximum was 360 in 1999. Poisoning by organophosphates was the most common method followed by hanging. This study, although limited in scope, provides evidence of an increase in suicide rates in Pakistan, from one data source. There is urgent need for further research on suicide in Pakistan; interventions for suicide prevention in the country can then be planned.     

Glucocorticoid-induced impairment of long-term memory retrieval in rats: an interaction with dopamine D2 receptors

This study investigated glucocorticoid-dopaminergic interactions in modulating retrieval of long-term memory in an inhibitory avoidance task. Young adult male rats were trained in one trial inhibitory avoidance task (0.5 mA, 3 s footshock). On the retention test given 48 h after training, the latency to re-enter the dark compartment of the apparatus was recorded. Systemically administered corticosterone (1 or 3 mg/kg) given to rats 30 min before retention testing impaired their memory retrieval, but the lower dose was more effective than the higher one. Administration of the dopamine (DA) D2 receptor antagonist sulpiride (6 or 20 mg/kg) 30 min before corticosterone attenuated the impairing effects of corticosterone (1 mg/kg) on memory retrieval. Administration of the DA D1 receptor antagonist SCH23390 (25 or 50 microg/kg) had no effect on corticosterone-induced impairment of memory retrieval. Further, applied doses of sulpiride or SCH23390 alone were ineffective in modulating memory retrieval. These findings provide evidence for the existence of an interaction between glucocorticoids and DA D2 receptor on memory retrieval process.     

Relations among hand preference,craniofacial asymmetry,and ear advantage in young subjects

The relations for hand preference with craniofacial asymmetry and ear advantage, and between craniofacial asymmetry and ear advantage were investigated in young healthy subjects. Ear advantage was recorded as duration of hearing, craniofacial asymmetry by computerized tomography in 44 right-handed and 38 left-handed male and female high school students. Right-handers had a right ear advantage and a larger left craniofacial region, whereas left-handers had a left ear advantage and a larger right craniofacial region. These results are consistent with the speculation that hand preference may be related to craniofacial and consequently aural asymmetries.     

Environmental education and socioresponsive engineering

A recent initiative at Muffakham Jah College of Engineering and Technology, Hyderabad, India, has resulted in setting up a program called Centre for Environment Studies and Socioresponsive Engineering which seeks to involve undergraduate students in studying and solving environmental problems in and around the city of Hyderabad, India. Two pilot projects have been undertaken — one focusing on design and construction of an eco-friendly house, The Natural House, and another directed at improving environmental and general living conditions in a slum area. The paper describes our attempts and experience of motivating our students to take interest in such projects. In an interesting development we invited a member of a student-faculty team at Massachusetts Institute of Technology (M.I.T.) that is doing a project in Nepal on safe drinking water. We report in our paper how the presentation by the guest from M.I.T. served as a catalyst for generating interest among civil and mechanical engineering students in our own projects. The paper includes contributions from one of our students and the M.I.T. staff member, reporting on their experiences related to the slum development project. We also discuss the Natural House project and its international and educational significance as a means of inculcating sensitivity and interest in nature among engineering students. We propose a pledge for engineers similar to the Hippocratic Oath for medical professionals.     

A self-contained,regulated, burst-firing constant-current ac shock generator

A line- and load-regulated constant-current ac shock generator has been designed for animal behavior experiments. The self-contained unit has four operating modes, amplitude adjustment, and a leakage current detection circuit. A unique feature of this generator is that the good load regulation achieved by using a high-voltage source is preserved without such problems as arcing and high current density effects. Circuit schematics, along with a discussion of selected circuits, are included. Experimental data are presented to demonstrate the utility of the device.     

Investigation of the factorial structure and psychometric properties of the Persian version of the Toronto Alexithymia Scale-20 in patients with psychiatric disorders

The aims of this study were to assess the factor structure, validity, and reliability of the Persian translation of the Toronto Alexithymia Scale-20 (TAS-20) and to examine different models of the TAS-20 in Iranian patients with various psychiatric disorders. Participants were 839 patients with psychiatric disorders, including obsessive-compulsive disorder (OCD) (n = 80), schizophrenia (n = 82), bipolar disorder (BD) (n = 100), alcohol dependence (n = 81), major depressive disorder (MDD) (n = 95), psychosomatic disorders (n = 92), anxiety disorders (n = 85), post-traumatic stress disorder (PTSD) (n = 90), attention deficit hyperactivity disorder (ADHD) (n = 55), and suicide attempts (n = 79). Results indicated that the three-factor TAS-16 fit the data well, after removing four items from the externally-oriented thinking (EOT) subscale. In addition, the total score and subscales had strong internal consistency and concurrent validity. An alternative three-factor model and a four-factor model, which both allow the reverse-coded EOT items to load on a separate factor, also had an acceptable fit. The results suggest that after deleting four items from the EOT subscale, the 16-item TAS is a reliable scale among Iranian psychiatric patients. Moreover, the alternative three-factor and four-factor structures may be appropriate to apply among Iranian patients.

     

Brief Report: Comparing the Autobiographical Remembering of Iranian Immigrant Trauma Survivors with That of Iranian and British Trauma Survivors

This study investigated how culture and posttraumatic stress disorder (PTSD) influence the autobiographical remembering of Iranian trauma survivors living in Britain compared to the remembering of British trauma survivors living in their host culture (Britain) and Iranians in their culture of origin (Iran). Iranian immigrants with and without PTSD completed measures of autobiographical remembering. Data was compared to previously collected data from British and Iranian trauma survivors with and without PTSD. It was found that the memory‐content of Iranian immigrants' memories resembled that of Iranian trauma survivors in Iran, while the phenomenological properties of their autobiographical remembering more closely resembled that of British trauma survivors. Moreover, there were pan‐cultural distortions and deficits in the autobiographical remembering of those with PTSD. The findings suggest that immigrants with PTSD have similar disruptions and distortions in their autobiographical remembering as that of individuals with PTSD living in their host culture and culture of origin.Copyright © 2016 John Wiley & Sons, Ltd.
