Item Development of a Language-Independent Functional Evaluation(Archives of Physical Medicine and Rehabilitation, 2009-12) Haig, A.J.; Jayarajan, S.; Maslowski, E.; Yamakawa, K.S.; Tinney, M.; Beier, K.P.; Juang, D.; Chan, L.; Boggess, T.; Loar, J.; Owusu-Ansah, B.; Kalpakjian, C.Haig AJ, Jayarajan S, Maslowski E, Yamakawa KS, Tinney M, Beier KP, Juang D, Chan L, Boggess T, Loar J, Owusu-Ansah B, Kalpakjian C. Development of a language-independent functional evaluation. Objective: To design, validate, and critique a tool for self-report of physical functioning that is independent of language and literacy. Design: Software design and 2 prospective trials followed by redesign. Setting: United States and African university hospitals. Participants: Outpatient and inpatient competent adults with diverse physical impairments. Interventions: (1) Software design process leading to a Preliminary Language-Independent Functional Evaluation (Pre-L.I.F.E.); (2) patient surveys using a printed Pre-L.I.F.E. and a computer-animated Pre-L.I.F.E. tested in random order, followed by a questionnaire version of the standard Barthel Index; and (3) software redesign based on objective and qualitative experiences with Pre-L.I.F.E. Main Outcome Measures: Validation of the general concept that written and spoken language can be eliminated in assessment of function. Development of a refined Language-Independent Functional Evaluation (L.I.F.E.). Results: A viable Pre-L.I.F.E. software was built based on design parameters of the clinical team. Fifty Americans and 51 Africans demonstrated excellent (Cronbach α>0.8 Americans) and good (α>.425 Africans) reliability. In general, the relations between Pre-L.I.F.E. and Barthel scores were excellent in the United States (interclass correlation coefficient for stair climbing, .959) but somewhat less good in Africa, with elimination functions very poorly related. The computer-animated Pre-L.I.F.E. was faster and trended to be more reliable than the printed Pre-L.I.F.E. in both the United States and Africa. Redesign meetings corrected statistical and qualitative challenges, resulting in a new tool, the L.I.F.E. Conclusions: Literacy and language translation can be eliminated from some aspects of functional assessment. The new L.I.F.E., based on solid empirical evidence and design principles, may be a practical solution to assessment of function in the global culture. © 2009 American Congress of Rehabilitation Medicine.Item Mental health policy in South Africa: Development process and content(Health Policy and Planning, 2009-06) Draper, C.E.; Lund, C.; Kleintjes, S.; Funk, M.; Omar, M.; Flisher, A.J.; Agossou, T.et.al.Introduction: Mental health is increasingly acknowledged as a crucial public health issue in South Africa (SA). However, it is not given the priority it deserves on policy agendas in this and many other low- and middle-income countries. The aim of this analysis is to describe the content of mental health policy and the process of its development in SA. Methods: Quantitative data regarding SA's mental health system were gathered using the World Health Organization (WHO) Assessment Instrument for Mental Health Systems. The WHO Checklist for Mental Health Policy and Plans was completed for SA's 1997 mental health policy guidelines. Semi-structured interviews provided understanding of processes, underlying issues and interactions between key stakeholders in mental health policy development. Results: There is uncertainty at provincial level regarding whether the 1997 policy guidelines should be considered national policy. At national level the guidelines are not recognized as policy, and a new policy is currently being developed. Although the guidelines were developed through wide consultation and had approval through national policy development processes, difficulties were encountered with dissemination and implementation at provincial level. The principles of these policy guidelines conform to international recommendations for mental health care and services but lack clear objectives. Discussion: The process of mental health policy implementation has been hindered by the low priority given to mental health, varying levels of seniority of provincial mental health coordinators, limited staff for policy and planning, varying technical capacity at provincial and national levels, and reluctance by some provincial authorities to accept responsibility for driving implementation. Conclusion: These findings highlight the importance of national leadership in the development of new mental health policy, communication between national and provincial levels, the need for provincial structures to take responsibility for implementation, and capacity building to enable policy makers and planners to develop, monitor and implement policy. © The Author 2009; all rights reserved.Item Integrating top-down with bottom-up conservation policy in Africa(Conservation Biology, 2009-08) Abrams, R.W.; Anwana, E.D.; Ormsby, A.; Dovie, D.B.K.; Ajagbe, A.; Abrams, A.Developed nations intervened in conservation policy across Africa during the 20th century to address needs to protect species and biodiversity that were based on their own perceptions and priorities. In the 21st century, conservationists in Africa have revised these perceptions and begun the process of identifying conservation priorities from an African perspective and in consideration of Africans' priorities. Although foreign conservation interveners struggled to identify mechanisms to which local people would respond, African conservationists are now demonstrating how to integrate the continent's unique socioeconomic circumstances into efforts to protect biodiversity. In Africa effective conservation policy must include the generation of wealth, reduction of disease and hunger, and support of traditional land-use practices. © 2009 Society for Conservation Biology.Item Enigmatic morphology of Djinga felicis (Podostemaceae - Podostemoideae), a badly known endemic from northwestern Cameroon(Botanical Journal of the Linnean Society, 2009-05) Ghogue, J.P.; Ameka, G.K.; Grob, V.; Huber, K.A.; Pfeifer, E.; Rutishauser, R.Djinga is a monotypic genus restricted to the Cameroon Ridge ('Dorsale Camerounaise') of NW Cameroon. Besides the type locality Mount Djinga (Adamawa Province, near Tignère), it also grows in waterfalls near Mount Oku (NW Province). This paper describes the structure and development of Djinga felicis using scanning electron microscopy and microtome sections. Cusset's protologue is enriched considerably. Roots are green, dorsiventrally flattened and adherent to submerged rocks. They are broad ribbons or crusts (up to 1 cm broad) which branch exogenously. Root-borne shoots (up to 17 cm) have filamentous leaves with sheaths and (occasionally) attached stipules. Flowers are borne as part of reproductive short shoots which arise exogenously along the stems and endogenously along the roots. Djinga shows non-axillary stem branching. Reproductive shoots along the main stem usually stay short. They arise from the abaxial side of double-sheathed leaves, a key innovation of Podostemoideae. These short shoots shift into pocket-like stem positions clearly below their associated leaves. Each flower bud inside a spathella is erect, but with an inclined ovary. The flowers are unistaminate with a broad connective. Unlike many other Podostemoideae, the tricolpate pollen grains are arranged in both dyads and monads. The ovary is globular and unilocular. The mature 8-ribbed capsule dehisces by two slightly unequal valves, releasing 40-50 seeds. © 2009 The Linnean Society of London.Item Global food chains, African smallholders and world bank governance(Journal of Agrarian Change, 2009-03) Amanor, K.S.This paper critically examines the World Bank's analysis of the development of agribusiness in Africa in the World Development Report 2008 in relationship to its governance policies, which seek to introduce institutional reforms to promote private and public sector linkages with the participation of civil society. The paper argues that this confuses food chain governance (control over quality and the logistics of production) with democratic governance and essentially promotes oligopolization of the food industry and the interests of the powerful in the name of smallholder farmers. © Journal compilation © 2009 Blackwell Publishing Ltd.Item Perceived incentives and barriers to exclusive breastfeeding among periurban ghanaian women(Journal of Human Lactation, 2009-02) Otoo, G.E.; Lartey, A.A.; Pérez-Escamilla, R.Focus group discussions were conducted to elicit the perceived incentives and barriers to exclusive breastfeeding in Ghana. Thirty-five breastfeeding women were recruited from the Manya and Yilo Krobo districts of the eastern region. Participants had a mean age of 27.5 years and had at least one child < 4 months old. Almost all of the participants believed that exclusive breastfeeding is the superior infant feeding method and should be practiced for the first 6 months postpartum. However, there was widespread belief that infants can be given water if it is clean. Mothers reported that exclusive breastfeeding was easier when breast milk began to flow soon after delivery. The main obstacles to exclusive breastfeeding identified were maternal employment, breast and nipple problems, perceived milk insufficiency, and pressure from family. Addressing the concerns put forward by these participants can be used to enhance exclusive breastfeeding promotion in this region. © Copyright 2009 International Lactation Consultant Association.Item Displaced women in Northern Ghana: Indigenous knowledge about ethnic conflict(Affilia - Journal of Women and Social Work, 2008-11) McGadney-Douglass, B.F.; Ahadzie, W.K.This article presents the findings of field research in Ghana in 2002 about internal displacement stemming from multiethnic violence in northern Ghana in 1994, known as the "Guinea Fowl War." Indigenous, gender-specific knowledge from displaced Ghanaian women is presented in the context of feminist perspectives on the consequences of regional wars on non-combatants. The research generated indigenous material for social work education about interethnic peace building and conflict resolution. The discussion includes first-person responses about warning signs, origins of conflict, immediate and long-term responses, social consequences, and an integration of findings with feminist perspectives on conflict resolution and policies that are designed to aid internally displaced women. © 2008 Sage Publications.Item Out of Africa: What can be learned from the studies of allergic disorders in Africa and Africans?(Current Opinion in Allergy and Clinical Immunology, 2008-10) Obeng, B.B.; Hartgers, F.; Boakye, D.; Yazdanbakhsh, M.Purpose of review Allergic diseases have only recently gained serious attention in Africa. This review discusses recent studies that have focused on allergy among Africans and people of African ancestry. Recent findings Time trend studies of the prevalence of allergies in Africa show a consistent increase over a period of 7-10 years. Recent studies have reported that the link between IgE, skin reactivity to allergens and allergic symptoms increases with increasing gross national income of the country. Association between helminth infections, and allergies seem contradictory, which may be attributed to differences in the length of infection and species studied. Importantly, researchers have identified an 'urban diet' component, which is associated with increased skin reactivity to allergens. Finally, whereas Africans in rural Africa seem to suffer less from allergies, people of African ancestry in affluent countries have higher prevalence and greater severity of allergic symptoms than natives of these host countries, raising important issues on genetic control of allergic diseases. Summary Mechanisms underlying the development of allergy are a complex interaction of genetic susceptibility and environmental exposures. Identification of specific environmental factors, mechanistic pathways and genetic risk factors in sufficiently powered studies will be necessary to better understand and control the allergic march in Africa and elsewhere. © 2008 Wolters Kluwer Health | Lippincott Williams & Wilkins.Item Self-reported suicidal behavior and attitudes toward suicide and suicide prevention among psychology students in Ghana, Uganda, and Norway(Crisis The Journal of Crisis Intervention and Suicide Prevention, 2008-02) Hjelmeland, H.; Akotia, C.S.; Owens, V.; Knizek, B.L.; Nordvik, H.; Schroeder, R.; Kinyanda, E.Self-reported suicidal behavior and attitudes toward suicide in psychology students are reported and compared in Ghana, Uganda, and Norway. Small differences only were found in own suicidal behavior. However, experience of suicidal behavior in the surroundings was more common in Uganda than in Ghana and Norway. Although differences were found between the three countries in attitudes toward suicide, which emphasizes the need for culture-sensitive research and prevention, many of the differences were not as big as expected. The most pronounced difference was that the Norwegian students were more reluctant to take a stand on these questions compared to their African counterparts. Some differences were also found between the two African countries. The implications of the results for suicide prevention in Africa are discussed. © 2008 Hogrefe & Huber Publishers.Item Comparative urbanization in Ghana and Kenya in time and space(GeoJournal, 2008-03) Otiso, K.M.; Owusu, G.There are few inter-African country urban analyses because of the continent's enormous size and socioeconomic diversity, language barriers, and wide variations in national and regional urban research capacity. Nevertheless, comparative urban studies are critical in understanding contemporary African urbanization. In this comparative spatial and temporal analysis of Ghana and Kenya's urbanization, we find that both countries are urbanizing rapidly and are faced with many common urban problems. Moreover, Ghana is more urbanized than Kenya and has a larger indigenous urban imprint and a more widely dispersed urban pattern. Besides their physiographic and population conditions, we trace these countries' convergent and divergent urban trends to their shared but unique experiences of colonialism, nationalism and globalization. © 2008 Springer Science+Business Media B.V.
