Response Surface Modeling and Optimization to Elucidate the Differential Effects of Demographic Characteristics on HIV Prevalence in South Africa
No full textComputers and Industrial Engineering 42, Cape Town, South Africa, 16-18 July 2012In this study, a Central Composite Face Centered (CCF) design was employed to study the individual and interaction effects of demographic characteristics on the spread of HIV in South Africa. The demographic characteristics studied for each pregnant mother attending an antenatal clinic in South Africa, were mother's age, partner's age, mother's level of education and parity. HIV status of an antenatal clinic attendee was found to be highly sensitive to changes in pregnant woman's age and partner's age, using the 2007 South African annual antenatal HIV and syphilis seroprevalence data. Individually the pregnant woman's level of education and parity had no significant effect on the HIV status. However, the latter two demographic characteristics exhibited significant effects on the HIV status of antenatal clinic attendees in two way interactions with other demographic characteristics. Using HIV as the optimization objective, the following summary statistics were obtained, R2 = 0.99 and two-factor interactions (2FI) model F-value of 63.77. The model F-value of 63.77 implied the 2FI model was significant and there was only a 0.01% chance this model value could occur due to noise. The model 'Lack of Fit' value of 0.01 implied that the 'Lack of Fit' was not significant relative to the pure error and thus there was a 99.88% chance that this 'Lack of Fit' F-value could occur due to noise. An adeq. precision value of 25 was obtained, suggesting that this 2FI model could be used to navigate the design space. A 3D response surface plot indicated that the highest rate of HIV positive individuals was obtainable at the highest age of the pregnant women and lowest age of their partners.http://dx.doi.org/10.1109/ASONAM.2012.149http://conferences.sun.ac.za/index.php/cie/cie-42/paper/view/252http://conferences.sun.ac.za/index.php/cie/cie-4

Variations on the Author
No full text“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship

Meningiomas occurring during long-term survival after treatment for childhood cancer
No full textChildhood cancer is rare but improvements in treatment over the past five decades have resulted in a cohort of more than 30,000 long-term survivors of childhood cancer in the UK with more added annually. These long-term survivors are at risk of late effects of cancer treatment which replace original tumour recurrence as the leading cause of premature death. Second neoplasms are a particular risk and in the central nervous system meningiomas occur increasingly with increased radiation dose to central nervous system tissue and length of time after exposure, resulting in a 500-fold increase above that expected in the normal population by 40 years of follow up. This multidisciplinary author group and others met to discuss the issue. Our pooled information, and consensus that screening should only follow symptoms, was published online by the Royal College of Radiologists in 2013. We outline here the current knowledge and management of these neoplasms secondary to childhood cancer treatment
