Urban growth boundary policy and residential suburbanization: Riyadh, Saudi Arabia

The process of suburbanization of Riyadh, a city of 4.5 million inhabitants, offers a unique situation in which the urban morphology of the city can be examined in light of socio-political and economic conditions. Central government ordinances helped create ‘dysfunctional’ sprawl by mandating big lots and overly wide streets. Fifty percent of the city’s urban plan of approximately 1300 km² represents a pattern of untimely, undeveloped subdivisions. Much of this premature sub-divisioning was a result of speculative land deals. The current area of undeveloped subdivided land is approximately 650 km², which is roughly the equivalent to the city’s land currently developed.The author argues that government policies and inefficient urban planning practices have encouraged the transformation of the peripheral desert landscape into unchecked land sub-divisioning championed by land developers and speculators. Using a comparative approach, the paper attempts to highlight sociopolitical and other cultural factors that underlie this inefficient sprawl at the fringe. It closes with recommendations to alleviate such a costly pattern that can be generalized to other developing world cities.     

Employment status, psychiatric disability and quality of life: comparison of men and women with schizophrenia in Malaysia

This study explores the association between employment opportunities, psychiatric disability and quality of life of male and female patients with schizophrenia. The data were collected from 100 male and 100 female patients and their primary caregivers through personal interviews. The Disability Assessment Schedule and the Quality of Life Interview were used to collect the data. The results of the present study indicate that a large number of both the men and women were unemployed, although they suffered from only mild psychotic symptoms and had no or only minimum psychiatric disability. However, in almost all areas and levels of psychiatric disability, a significantly higher number of men than women were employed. However, the subjective Quality of Life of the employed men was significantly lower than that of the unemployed. Keeping in mind these two results, the present study argues that there is minimal community recognition in Malaysia for the employment potential of people with schizophrenia. The study also argues that policy makers must legislate to create more appropriate workplaces for the mentally ill. People with schizophrenia are entitled to just and fair treatment, and workplaces should be made attractive to them.     

Long-term low-dose dehydroepiandrosterone replacement therapy in aging males with partial androgen deficiency

Dehydroepiandrosterone (DHEA) and dehydroepiandrosterone sulfate (DHEAS) age-related withdrawal is very likely to be involved in the aging process and the onset of age-related diseases, giving rise to the question of whether preventing or compensating the decline of these steroids may have endocrine and clinical benefits. The aim of the present trial was to evaluate the endocrine, neuroendocrine and clinical consequences of a long-term (1 year), low-dose (25?mg/day) replacement therapy in a group of aging men who presented the clinical characteristics of partial androgen deficiency (PADAM). Circulating DHEA, DHEAS, androstenedione, total testosterone and free testosterone, dihydrotestosterone (DHT), progesterone, 17-hydroxyprogesterone, allopregnanolone, estrone, estradiol, sex hormone binding globulin (SHBG), cortisol, follicle stimulating hormone (FSH), luteinizing hormone (LH), growth hormone (GH) and insulin-like growth factor 1 (IGF-1) levels were evaluated monthly to assess the endocrine effects of the therapy, while β-endorphin values were used as a marker of the neuroendocrine effects. A Kupperman questionnaire was performed to evaluate the subjective symptoms before and after treatment.

The results showed a great modification of the endocrine profile; with the exception of cortisol levels, which remained unchanged, DHEA, DHEAS, androstenedione, total and free testosterone, DHT, progesterone, 17-hydroxyprogesterone, estrone, estradiol, GH, IGF-1 and β-endorphin levels increased significantly with respect to baseline values, while FSH, LH and SHBG levels showed a significant decrease. The Kupperman score indicated a progressive improvement in mood, fatigue and joint pain.

In conclusion, the present study demonstrates that 25?mg/day of DHEA is able to cause significant changes in the hormonal profile and clinical symptoms and can counteract the age-related decline of endocrine and neuroendocrine functions. Restoring DHEA levels to young adult values seems to benefit the age-related decline in physiological functions but, however promising, placebo-controlled trials are required to confirm these preliminary results.     

An Arab perspective on social media: How banks in Kuwait use instagram for public relations

This study examines the public relations functions of eight Kuwaiti banks listed in the Kuwait Stock Exchange Market (KSEM) that post on their Instagram accounts. It also uses market-size, organization, and individual level predictors to model Instagram postings. A content analysis of 1502 posts revealed the banks use Instagram for promotion, information dissemination, community building, and interactive engagement, in that order of prominence. The findings suggest banks operate at the confluence of visual communication through Instagram and integration of religious symbolism to serve a public relations function predicated on image and influence. In doing so, the banks tap into the wellspring of social media use by target publics by navigating a balance between obedience to Allah and meeting bank business objectives. The resulting tension between sacred and secular highlights Arab cultural values and suggests Instagram fosters individualism, which challenges Arab emphasis on collectivism and fractures the notion online platforms can effectively build meaningful relationships that characterize Arab culture. The study posits Instagram is more effective in an Arab context at image building than relationship building, threading the importance of visual communication through social media across Arab culture and global public relations practices.     

An approach to the treatment evaluation of Hodgkin's disease

Hodgkin's disease is a cancer of the lymphatic system. The major feature influencing the type of treatment employed, and the ultimate prognosis, is the stage or extent of disease prior to therapy. This paper is concerned with evaluating the difference in patient progress of two staging procedures. One (pathological staging) procedure is more extensive than the other (clinical staging). The evaluation is carried out by firstly developing a mathematical model of patient progress for pathologically staged patients and then using this model to predict what would have happened to clinically staged patients if they had been treated according to their pathological stage. Comparison of these predictions with actual results suggests that pathologically staged patients appear to remain in disease free survival (remission) following radio-therapy longer than clinically staged patients.
