    Africa on the rise: prospects for growth and development
    (2014-09-29) Rotberg, Robert
    This course will demonstrate how sub-Saharan Africa is emerging successfully from its long era of stagnation, conflict and troubled democracy to provide prosperity and real hope for its peoples. It will discuss prospects for future economic growth, for political and social success and for the creation of a new middle class. It will consider prospects for a demographic dividend as populations expand and cities grow and fill with young people, reducing conflict and social ills. Health and educational requirements, the contribution of mobile phones to change, China’s important role, good governance, good leadership, and the role that South Africa can play in the new Africa, will all be explored. LECTURE TITLES 1. Africa’s new prosperity: rapid growth and more to come 2. The coming population explosion and its consequences 3. The mobile telephone revolution and its impact on health and educational reforms 4. China’s role for good and ill 5. Governance, leadership and the role of South Africa

    Assessing the palliative care needs of elderly patients seen at the University College Hospital, Ibadan, Nigeria
    (2020) Omoyeni, Eunice Nkechi; Gwyther, Elizabeth; Soyannwo, Olaitan A
    Background Nigeria, with a population growth rate (2000-2005) of 2.5% and with 5% of the total population aged 60 years and above, has the potential for a rapid growth rate of the older population in coming years.1 The implication of this in a country with large population as reported by the National Population Census 2006, limited number of health care professionals and care homes, is difficulty in meeting the various needs of the elderly, hence, the importance of identifying the palliative care needs of the elderly. Aim The study was set out to assess the palliative care needs of and provision of care to elderly patients seen in the selected clinics of the University College Hospital, Ibadan, Oyo state, Nigeria. Objectives 1. To describe characteristics of elderly patients seen in the selected clinics. 2. To explore the current use of the hospital palliative care team in the care of geriatric patient. 3. To explore the current use of the hospital palliative care team in the care of geriatric patient. Methods A descriptive cross-sectional study was conducted over a 3-month period using an interviewer administered questionnaire after full consent was given by participants. The questionnaire was a combination of the Africa Palliative Care Outcome Scale (APCA-POS), the Edmonton Symptom Assessment Scale (ESAS) and Hope Spiritual Assessment Tool. Demographic information regarding gender, age, nationality, abode and referral to the Care Centre was obtained. Scaled questions from selected tools were ticked with respect to physical, psychosocial and spiritual needs and expectations of palliative care. The validated data collection tools (APCA-POS, ESAS, HOPE) were used in the questionnaire. Ethical approval was obtained from the relevant organizations. Data was analysed using IBM SPSS statistics 21. Results 424 participants completed the questionnaire and most patients (330; 77.8%) were recruited from the geriatric wards with a 2:1 female to male ratio. Most participants fell in the 60 -69 year-old age group. The most common symptom was pain in 240 patients with moderate pain in single or multiple areas. A high percentage (45.8%) were moderately worried about their disease condition and only 66 out of 422 freely discussed this feeling with their family members. Other symptoms observed were nausea, vomiting, constipation and loss of appetite. Conclusion The study showed the palliative care needs of the elderly and calls for collaboration between the palliative care team and the physicians in the geriatric unit for better management of the needs of the elderly.

    Landscape requirements of a primate population in a human-dominated environment
    (BioMed Central Ltd, 2012) Hoffman, Tali; O'Riain, M Justin
    INTRODUCTION: As urban and rural land development become widespread features of the global landscape so an understanding of the landscape requirements of displaced and isolated wildlife species becomes increasingly important for conservation planning. In the Cape Peninsula, South Africa, rapid human population growth, and the associated urban and rural land transformation, threatens the sustainability of the local chacma baboon population. Here we analyse spatial data collected from nine of the 12 extant troops to determine their population-level landscape requirements. We use hurdle models to ascertain the key landscape features influencing baboon occurrence and abundance patterns on two hierarchical spatial scales. RESULTS: Both spatial scales produced similar results that were ecologically reliable and interpretable. The models indicated that baboons were more likely to occur, and be more abundant, at low altitudes, on steep slopes and in human-modified habitats. The combination of these landscape variables provides baboons with access to the best quality natural and anthropogenic food sources in close proximity to one another and suitable sleeping sites. Surface water did not emerge as an influential landscape feature presumably as the area is not water stressed. CONCLUSIONS: The model results indicate that land development in the Cape Peninsula has pushed baboons into increasingly marginal natural habitat while simultaneously providing them with predictable and easily accessible food sources in human-modified habitats. The resultant spatial competition between humans and baboons explains the high levels of human-baboon conflict and further erosion of the remaining land fragments is predicted to exacerbate competition. This study demonstrates how the quantification of animal landscape requirements can provide a mechanism for identifying priority conservation areas at the human-wildlife interface.
