  1. The African Development Bank, structural adjustment, and child mortality: a cross-national analysis of Sub-Saharan Africa.

    PubMed

    Pandolfelli, Lauren E; Shandra, John M

    2013-01-01

    We conduct a cross-national analysis to test the hypothesis that African Development Bank (AfDB) structural adjustment adversely impacts child mortality in Sub-Saharan Africa. We use generalized least square random effects regression models and two-step Heckman models that correct for selection bias using data on 35 nations with up to four time points (1990, 1995, 2000, and 2005). We find substantial support for our hypothesis, which indicates that Sub-Saharan African nations that receive an AfDB structural adjustment loan tend to have higher levels of child mortality than Sub-Saharan African nations that do not receive such a loan. This finding remains stable even when controlling for selection bias on whether or not a Sub-Saharan African nation receives an AfDB structural adjustment loan. We conclude by discussing the methodological implications of the article, policy suggestions, and possible directions for future research.

    The history of tissue banking is as old as the use of skin grafting for resurfacing of burn wounds. Beneficial effects of tissue grafts led to wide spread use of auto and allograft for management of varied clinical conditions like skin wounds, bone defects following trauma or tumor ablation. Availability of adequate amount of tissues at the time of requirement was the biggest challenge that forced clinicians to find out techniques to preserve the living tissue for prolonged period of time for later use and thus the foundation of tissue banking was started in early twentieth century. Harvesting, processing, storage and transportation of human tissues for clinical use is the major activity of tissue banks. Low temperature storage of processed tissue is the best preservation technique at present. Tissue banking organization is a very complex system and needs high technical expertise and skilled personnel for proper functioning in a dedicated facility. A small lapse/deviation from the established protocol leads to loss of precious tissues and or harm to recipients as well as the risk of transmission of deadly diseases and tumors. Strict tissue transplant acts and stringent regulations help to streamline the whole process of tissue banking safe for recipients and to community as whole. PMID:23162240

  8. Developing anatomical terms in an African language.

    Clinical and technical information imparted in most African languages involves inexact terminology and code switching, so it lacks the explanatory power characterised by the English language. African languages are absent in the tertiary science education environment and forums where African scientists could present scientific material in the medium of African languages. This limits the development of African languages in the scientific domain. There has recently been a trend in several African languages to develop and intellectualise them, especially in the field of medical sciences. The ChiShona language is used to explore the ability of an African language to develop new terminology, to name the vertebral skeleton and describe it scientifically. It uses word compounding to demonstrate terminology development. ChiShona has similarities with several hundred other Bantu languages in East, Central and Southern Africa. Advancing this language can promote similar developments in others, making them more explanatory for the lay public and health professionals.

  12. Grameen Bank`s experience with energy related microenterprise development

    SciTech Connect

    1997-12-01

    Increased population and growth of industry have resulted in greater demand for energy worldwide. Most of this energy is derived from fossil fuel (coal, gas, oil and nuclear) which will soon be depleted. In this context the need for developing renewable sources of energy has taken on a greater sense of importance and urgency. Over the years significant technological advances have been made in the area of renewable energies especially in the field of solar photovoltaics (PV), wind energy and bio-gas technology. In addition, for remote rural areas where there exists no infrastructure for conventional energy supply, these forms of decentralized alternative energy systems will be far more adaptable and well suited. Grameen Shakti (Energy) is an addition to the family of companies of Grameen Bank, to promote and supply renewable energy sources to rural households. GS, a not-for-profit company, expects not only to supply renewable energy services, but also to create employment and income generation opportunities in rural Bangladesh. GS will focus on supply, marketing, sales, testing and development of renewable energy systems of solar pv, biogas, wind turbines and windpumps.

    In an effort to make countries in Latin America and the Caribbean less vulnerable to natural disasters, the Inter-American Development Bank (IDB) announced on 21 December 2005 that it has developed a new draft disaster risk management policy to encourage its member countries to plan for these events. The IDB, the major development bank for the region, decided to place a focus on natural disaster risk planning following several devastating disasters in the region in the 1990s, including 1998's Hurricane Mitch, said Caroline Clarke, IDB senior specialist in disaster prevention and risk management. The IDB provides loans, technical assistance, and policy guidance to reduce poverty and promote sustainable development in Latin America and the Caribbean.

  14. World Bank predicts development for next century.

    1999-09-18

    The World Bank reports that localization and globalization will be the two primary forces that will dominate the trend in the next millennium. These trends could either revolutionize human development or lead to greater chaos and suffering. The report further examines three aspects of globalization: trade, capital flows and environment; and three aspects of localization: decentralization, cities and making livable cities. It focuses on the impact of these two forces on the poor and their health. It stated that economic growth in the past 30 years had little impact on indicators of real development such as political stability, education, life expectancy, and gender equality. Moreover, a weak correlation between income and standard of living exists because countries and communities placed different priorities on education and health. The recommendations of the bank include the need for macroeconomic stability and a socially flexible sustained development.

    Before 1986, the development of tissue banking in China has been slow and relatively uncoordinated. Under the support of International Atomic Energy Agency (IAEA), Tissue Banking in China experienced rapid development. In this period, China Institute for Radiation Protection tissue bank mastered systematic and modern tissue banking technique by IAEA training course and gradually developed the first regional tissue bank (Shanxi Provincial Tissue Bank, SPTB) to provide tissue allograft. Benefit from training course, SPTB promoted the development of tissue transplantation by ways of training, brochure, advertisement and meeting. Tissue allograft transplantation acquired recognition from clinic and supervision and administration from government. Quality system gradually is developing and perfecting. Tissue allograft transplantation and tissue bank are developing rapidly and healthy.

  2. Some growth points in African child development research.

    2014-01-01

    We reflect on ways in which research presented in earlier chapters responds to challenges of generating an African child development field and identify additional issues calling for the field's attention. The chapters collectively display a variety of African contexts and reflexive evidence of the authors' African cultural roots. Connecting research with African audiences demands cooperative communication between educational practitioners and parents with low literacy, and cross-sector communication among professionals. Intracultural exploration of factors influencing the pattern of human development has begun to document the potential of indigenous African cultures as a fund of resources for enhancing child development. Priority topics for future African developmental research include multilingualism, musical performance, socially distributed caregiving, and the relation between adolescence and economic activity. Integration of multiple disciplines in the application of research-based principles to service delivery in the fields of community-based (re)habilitation and early childhood care and education calls for researcher collaboration with practitioners.

  3. The impact of HIV/AIDS on human development in African countries

    PubMed Central

    2009-01-01

    Background In the present paper, we consider the impact of HIV/AIDS on human development in African countries, showing that, beyond health issues, this disease should and must be seen as a global development concern, affecting all components of human development. Consequently, we stress the necessity of multidisciplinary approaches that model, estimate and predict the real impact of HIV/AIDS on human development of African countries in order to optimise the strategies proposed by national countries, international institutions and their partners. Methods In our search strategy, we relied on secondary information, mainly through National Human Development Reports of some African countries and regular publications released by the United Nations (UN), United Nations Development Programme (UNDP), World Health Organization (WHO) and the World Bank. We restricted ourselves to reports dealing explicitly with the impact of HIV/AIDS on human development in African countries. Results and discussion HIV/AIDS is affecting the global human development of African countries through its devastating impact on health and demographic indicators such as life expectancy at birth, healthcare assistance, age and sex distribution, economic indicators like income, work force, and economic growth, education and knowledge acquisition and other indicators like governance, gender inequality and human rights. Conclusion On the basis of the national reports reviewed, it appears clearly that HIV/AIDS is no longer a crisis only for the healthcare sector, but presents a challenge to all sectors. Consequently, HIV/AIDS is a development question and should be viewed as such. The disease is impeding development by imposing a steady decline in the key indicators of human development and hence reversing the social and economic gains that African countries are striving to attain. Being at the same time a cause and consequence of poverty and underdevelopment, it constitutes a challenge to human security

  4. Oil imports and the foreign debt of developing African countries

    1987-07-01

    This study examines the oil transactions between 1971 and 1983 of African nations supported by the Agency for International Development, with the objective of estimating the proportion of current indebtedness attributable to crude oil price increases. A data base was constructed, drawing on information from several data series of the International Monetary Fund, the World Bank, and the United Nations. These data were examined using a series of alternative formulas that controlled for particular characteristics of nations with and without oil refineries and controlled, to some degree, for data deficiencies. The results indicate that oil price increases have played a prominent role in debt creation, though perhaps a lesser role than some had suggested. Estimates of the share of debt incurred due to oil price increases range from less than one-third to more than two-thirds. The recent decreases in oil prices may relieve some pressures for continued debt accumulation, although a reduction in pressures is likely to occur less slowly than price decreases. The vulnerability of developing countries to oil price increases underlines the attractiveness of development projects that lessen reliance on imported oil and oil products.

  7. The development role of community banks in rural Nigeria.

    PubMed

    Onugu, C U

    2000-02-01

    This paper examined the development role of community banks in rural Nigeria by using the deposit mobilization capability and funding capacity in key sectors of the rural economy as yardsticks. By using a cluster sampling technique, it looks at the achievements of the community banking scheme initiative in terms of economic development. The scheme, established in 1991, has sustained itself and promoted rural development in the country. It is noted that communities have, for the first time, realized that they can advance their own economic fortunes. However, the scheme's performance as supporter of the agricultural sector has not been as well as expected, despite the fact that agriculture dominates Nigeria's rural economy. In view of this, non-banking activities are a welcome development since some of their approaches are proven to be knowledge enhancing and empowering for the rural population. Overall, community banks should attempt to strengthen non-banking approaches by collaborating more with self-help groups or nongovernmental organizations to be more empowering, results-oriented, and sustainable. Moreover, regulatory authorities should ensure that guidelines relate to credit application in terms of volume and sector allocation.

  8. Women and the social construction of gender in African development.

    PubMed

    Kalu, A C

    1996-01-01

    Because a footnote of Marxism teaches that capitalism must first destroy primitive cultures that lack a dynamic social change mechanism and then rejuvenate them as modern industrialized states, the economic and cultural bases of social relationships in developing countries have been deemed irrelevant. In a similar way, Western feminist paradigms fail to acknowledge epistemological differences from those of African women. This article explores these contradictions and analyzes social change mechanisms within the Igbo culture in Africa that were stunted by colonialism. The first topic considered is the relationship of African literature (using Toni Morrison's "Beloved" as a point of reference) with sustainable African development and African women. The remainder of the article is devoted to an examination of the role of women in light of precolonial and colonial literary traditions. It is noted that continued use of Western feudal and capitalist terms for self-identification alienates Africans from Africa's problems. Traditional African thought assigned women the power to feed the family and to serve as protectors of children and society, and ancestral wisdom directed how societies responded to threats, took charge of their world, and resolved conflict. Problems faced by contemporary African researchers are shown to center on the dilemma faced by those who wish to design a program that analyzes the content of African development and provides contemporary solutions without completely deriving the program completely from contemporary thought. It is, thus, concluded that redefinition of the African development agenda must involve recognition of the essential role of African women as a change agent and a rearticulation of the male role within traditional thought.

    Diabetes has been detected in Danish and Swedish bank voles (Myodes glareolus). There are no data, however, concerning the prevalence of diabetes in populations from other geographic regions. We investigated the frequency and physiological effects of glucose metabolism disorders in captive bank voles from Poland. Single measurement of fasting blood glucose concentration performed in the 3-4month old captive-born bank Polish voles without any disease symptoms showed that 8% of individuals (22/284) displayed an impaired fasting glucose (IFG, blood glucose (BG) ≥100mg/dL) and 1% (4/284) showed hyperglycemia (BG ≥126mg/dL) which could suggest diabetes. Next, we analyzed blood glucose in samples taken once a month from an additional cohort of bank voles with (FHD), or without (H), a family history of diabetes. The prevalence of IFG at age six months was 26% (16/62) among bank voles from the H group. In the FHD group the prevalence increased to 49% (43/88), and additional 12% (11/88) became diabetic (DB, BG ≥126mg/dL at two time points). Postnatal stress (three maternal deprivations before weaning) did not affect the risk of developing IFG or DB in H voles, but significantly reduced the frequency of glucose metabolism disorders (IFG and DB combined) in FHD voles. IFG was associated with hyperinsulinemia, but not with other biochemical disturbances. Diabetic animals displayed a progressive malformation and vacuolization of β-cells in the pancreas, without visible leukocytic infiltrations. In summary, our results indicate that Polish captive bank voles can develop diabetes, which shows features of both type 1 and type 2 diabetes in humans. Risk of diabetes is higher in animal with FHD.

    This paper describes the psychometric properties of the PROMIS Pain Interference (PROMIS-PI) bank. An initial candidate item pool (n=644) was developed and evaluated based on review of existing instruments, interviews with patients, and consultation with pain experts. From this pool, a candidate item bank of 56 items was selected and responses to the items were collected from large community and clinical samples. A total of 14,848 participants responded to all or a subset of candidate items. The responses were calibrated using an item response theory (IRT) model. A final 41-item bank was evaluated with respect to IRT assumptions, model fit, differential item function (DIF), precision, and construct and concurrent validity. Items of the revised bank had good fit to the IRT model (CFI and NNFI/TLI ranged from 0.974 to 0.997), and the data were strongly unidimensional (e.g., ratio of first and second eigenvalue = 35). Nine items exhibited statistically significant DIF. However, adjusting for DIF had little practical impact on score estimates and the items were retained without modifying scoring. Scores provided substantial information across levels of pain; for scores in the T-score range 50-80, the reliability was equivalent to 0.96 to 0.99. Patterns of correlations with other health outcomes supported the construct validity of the item bank. The scores discriminated among persons with different numbers of chronic conditions, disabling conditions, levels of self-reported health, and pain intensity (p< 0.0001). The results indicated that the PROMIS-PI items constitute a psychometrically sound bank. Computerized adaptive testing and short forms are available. PMID:20554116

    1993-01-01

    The 3rd African Population Conference, held in Dakar, Senegal, December 7-12, 1992, adopted the draft Dakar/Ngor Declaration on Population, Family and Sustainable Development in preparation for the 1994 Cairo International Conference on Population and Development. The meeting was attended by 50 member states and many observers from various United Nations Organizations and nongovernmental organizations (NGOs). The Conference reviewed the lessons learned from the implementation of the Kilimanjaro Program of Action on Population (KAP), which had been adopted in 1984. The draft Declaration focused on the following areas: a) population, sustained economic growth, and sustainable development; family; fertility and family planning; mortality, morbidity and AIDS; urbanization and migration; refugees and displaced persons; women in development; children; data collection and analysis, information dissemination, training and research; information, education and communication; b) the role of: private and nongovernmental organizations; the subregional and regional groupings; the World Bank and relevant organizations of the United Nations System; and the international community; c) resource mobilization; and d) implementation of the Declaration. African countries should integrate population policies so as to reduce population growth from the present rate of 3.0% per annum to 2.5% by the year 2000 and to 2% by the year 2010. Environmental issues and food security were given special attention. The targets set on the contraceptive prevalence rate for Africa were to reach 20% by the year 2000 and 40% by the year 2010. The following targets were to be attained by the year 2000: life expectancy in Africa at least 55 years; an infant mortality rate of less than 50 per 1000 live births; childhood mortality rate of 70 or less. Programs to prevent AIDS were also stressed. The Declaration called on UN organizations, the World Bank, the Organization of African Unity, and the African

    Introduction: Smokers’ health-related outcome expectancies are associated with a number of important constructs in smoking research, yet there are no measures currently available that focus exclusively on this domain. This paper describes the development and evaluation of item banks for assessing the health expectancies of smoking. Methods: Using data from a sample of daily (N = 4,201) and nondaily (N = 1,183) smokers, we conducted a series of item factor analyses, item response theory analyses, and differential item functioning analyses (according to gender, age, and race/ethnicity) to arrive at a unidimensional set of health expectancies items for daily and nondaily smokers. We also evaluated the performance of short forms (SFs) and computer adaptive tests (CATs) to efficiently assess health expectancies. Results: A total of 24 items were included in the Health Expectancies item banks; 13 items are common across daily and nondaily smokers, 6 are unique to daily, and 5 are unique to nondaily. For both daily and nondaily smokers, the Health Expectancies item banks are unidimensional, reliable (reliability = 0.95 and 0.96, respectively), and perform similarly across gender, age, and race/ethnicity groups. A SF common to daily and nondaily smokers consists of 6 items (reliability = 0.87). Results from simulated CATs showed that health expectancies can be assessed with good precision with an average of 5–6 items adaptively selected from the item banks. Conclusions: Health expectancies of smoking can be assessed on the basis of these item banks via SFs, CATs, or through a tailored set of items selected for a specific research purpose. PMID:25118229

    The focus of this article is the development of a nutrition education intervention for food bank clients. Formative research using mixed-methods (qualitative and quantitative) and community-based participatory research principles was conducted to assess the nutrition education needs of clients obtaining service from the Houston Food Bank (HFB). Participants were HFB and pantry staff and clients. Interview data were coded and analyzed using grounded theory approach. Themes were then identified. Quantitative data were analyzed for frequencies and descriptives. Data were used to tailor the curriculum to the target population. Six HFB staff, 49 pantry staff from 17 pantries, and 54 clients from 10 pantries participated in interviews and focus groups and completed questionnaires. The participants provided opinion on the current nutrition education provided via the food bank and made suggestions on strategies for development of an intervention. Their feedback was used to develop the six-session intervention curriculum to be delivered over 6 months. This research provides evidence that it is critical for members of the target audience be included in formative research to develop behavior change programs that are relevant and appealing and target their needs and interests.

    Objective To describe the qualitative development of the Patient-Reported Outcome Measurement Information System (PROMIS®) Pediatric Stress Response item banks. Methods Stress response concepts were specified through a literature review and interviews with content experts, children, and parents. A library comprising 2,677 items derived from 71 instruments was developed. Items were classified into conceptual categories; new items were written and redundant items were removed. Items were then revised based on cognitive interviews (n = 39 children), readability analyses, and translatability reviews. Results 2 pediatric Stress Response sub-domains were identified: somatic experiences (43 items) and psychological experiences (64 items). Final item pools cover the full range of children’s stress experiences. Items are comprehensible among children aged ≥8 years and ready for translation. Conclusions Child- and parent-report versions of the item banks assess children’s somatic and psychological states when demands tax their adaptive capabilities.

    Human milk is very valuable in premature infant nutrition. The collection, screening, processing and distribution of donor human milk are described in this report. These activities take place in the Donor Human Milk Bank (DHMB) of the Large Romagna Area (LRA) in Italy, the development of which is also described here. Over the years, the activities of this bank, which is located in Cesena Hospital, in the center of the LRA, have developed from an informal and domestic-level activity to become a multistep controlled process designed to prevent the possibility of disease transmission. This little food-supply industry, run by a multi-disciplinary team with strict rules and diverse responsibilities, complies with the Hazards Analysis and Critical Control Points (HACCP) system.

    2013-10-11

    The largest impact on the South African burden of disease will be made in community-based and primary healthcare (PHC) settings and not in referral hospitals. Medical generalism is an approach to the delivery of healthcare that routinely applies a broad and holistic perspective to the patient's problems and is a feature of PHC. A multi-professional team of generalists, who share similar values and principles, is needed to make this a reality. Ward-based outreach teams include community health workers and nurses with essential support from doctors. Expert generalists - family physicians - are required to support PHC as well as provide care at the district hospital. All require sufficient training, at scale, with greater collaboration and integration between training programmes. District clinical specialist teams are both an opportunity and a threat. The value of medical generalism needs to be explained, advocated and communicated more actively.

    This paper describes the Horizontal Subsea Production Tree System, later referred to as a SpoolTree{trademark}, developed for the Enserch Garden Banks 388 field in the Gulf of Mexico. The paper starts with a project overview followed by a comparison between the SpoolTree and the Conventional Tree design. A brief discussion explains why Enserch elected to use the SpoolTree for this field development, including available technology, workover frequency, cost etc. The rigorous safety analysis carried out for the subsea production equipment is then explained in depth. The paper continues with a technical discussion of the main features specific to the SpoolTree design and the Garden Banks 388 field development. Issues discussed include the SpoolTree itself, BOP Adapter Plate (for control during installation, workover and production), Tubing Hanger and pressure barrier design, debris cap design, downhole communication (SCSSV, chemical injection, pressure and temperature) ROV intervention, template wellbay insert design and other relevant issues. The use of computer based 3-D modelling tool is also briefly described. The experience and results described in this paper have direct application to numerous subsea development prospects worldwide, particularly in deep water. In addition, the ``system development`` aspect of the project is relevant to most marine equipment development projects. This includes the use of safety analysis techniques, 3-D computer modelling tools and clearly defined engineering procedures. A full account of the final design configuration of the SpoolTree system is given in the paper. A summary of the experience gained during the extensive testing at the factory and during the template integration tests is also provided.

  9. The income-climate trap of health development: a comparative analysis of African and Non-African countries.

    PubMed

    2009-10-01

    This article conducts a comparative analysis of the interrelationship between climate, life expectancy and income between African and non-African countries. To put the analysis in a broader context of development, the paper develops an income-climate trap model that explains the multi-directional interaction between income, climate and life expectancy. It is suggested that the interaction can give rise to either a virtuous cycle of prosperity or a vicious cycle of poverty. Applying the model to a data set of 158 countries, we find that climate is a more important determinant of life expectancy in African countries than in non-African countries. We provide further empirical evidence that while climate is important in determining both life expectancy and income, income can in turn moderate the adverse effects of climate on life expectancy. In the past two decades, the income level of non-African countries has grown significantly while that of African countries has largely been stagnant, implying that the future development of African countries remains highly vulnerable to adverse climatic conditions. These findings have important implications in the context of climate change, as global warming is likely to create worsening climatic conditions that could see many less developed countries sinking deeper into an income-climate trap of underdevelopment in health.

    NASA Astrophysics Data System (ADS)

    Mangoyana, Robert Blessing

    This paper assesses the sustainability concerns of bioenergy systems against the prevailing and potential long term conditions in Sub-Saharan Africa with a special attention on agricultural and forestry waste, and cultivated bioenergy sources. Existing knowledge and processes about bioenergy systems are brought into a “sustainability framework” to support debate and decisions about the implementation of bioenergy systems in the region. Bioenergy systems have been recommended based on the potential to (i) meet domestic energy demand and reduce fuel importation (ii) diversify rural economies and create employment (iii) reduce poverty, and (iv) provide net energy gains and positive environmental impacts. However, biofuels will compete with food crops for land, labour, capital and entrepreneurial skills. Moreover the environmental benefits of some feedstocks are questionable. These challenges are, however, surmountable. It is concluded that biomass energy production could be an effective way to achieve sustainable development for bioenergy pathways that (i) are less land intensive, (ii) have positive net energy gains and environmental benefits, and (iii) provide local socio-economic benefits. Feasibility evaluations which put these issues into perspective are vital for sustainable application of agricultural and forest based bioenergy systems in Sub-Saharan Africa. Such evaluations should consider the long run potential of biofuels accounting for demographic, economic and technological changes and the related implications.

  17. Seismicity and seismotectonics of the diffusive Iberian/African plate boundary: Horseshoe Abyssal Plain and Gorringe Bank

    Grevemeyer, Ingo; Lange, Dietrich; Matias, Luis

    2014-05-01

    In the area to the west of the Gibraltar Arc the plate boundary between Africa and Iberia is poorly defined. The deformation in the area is forced by the slow NW-SE convergence of 4 mm/yr between the oceanic domains of Iberia/Eurasia and Africa and is accommodated over a 200 km broad tectonically-active deformation zone. The region, however, is also characterized by large earthquakes and tsunamis, such as the 1969 Mw=7.9 Horseshoe Abyssal Plain earthquake and the November 1, 1755 Great Lisbon earthquake with an estimated magnitude of Mw~8.5. The exact location of the source of the 1755 Lisbon earthquake is still unknown. Recent work may suggest that the event occurred in the vicinity of the Horseshoe fault, an oblique thrust fault. However, estimates of tsunami arrival times suggested a source near the Gorringe Bank, a ~180 km-long and ~70 km-wide ridge that has a relieve of ~5000 m. Deep Sea Drilling (DSDP) and rock samples indicated that the bank is mainly composed of serpentinized peridotites with gabbroic intrusions, perhaps being created by overthrusting of the Horseshoe Abyssal Plain onto the Tagus Abyssal Plain in NW direction. Further, the Horseshoe Abyssal Plain is marked by the presence of compressive structures with a roughly NE-SW orientation and E-W trending, segmented, crustal-scale, strike slip faults that extend from the Gorringe Bank to the Gibraltar Arc in the eastern Gulf of Cadiz, which were called "South West Iberian Margin" or SWIM faults. The fault system may mark a developing Eurasia-Africa plate boundary. Two local seismic networks were operated in the area. First, a network of 14 ocean-bottom seismometers (OBS) was operated between April and October 2012 in the vicinity of the Horseshoe fault between 10°W to 11°W, and 35°50'N to 36°10'N. From October 2013 to March 2014 a second network of 15 OBS monitored seismicity at the Gorringe Bank. Both networks benefitted from seismic stations operated in Portugal.

  19. African women, industrialization and another development. A global perspective.

    Historically, the women of Africa have been differentially integrated into the world economic system, serving primarily as a labor reserve and a mainstay for the subsistence and reproductive sectors. If and when necessary, female proletarianization can come into effect. African women, by virtue of their strategic role in traditional food systems, have acquired certain skills compatible with labor intensive food processing industries. Consequently, in some countries they have been involved in the handling, processing, and packing of food. In many 3rd world nations regulations protecting minimum wage levels do not exist and collective bargaining activities are not strongly in force. Economic hardship and the desperate need to survive can lead some groups to accept even lower wages. Consequently, although the employment of women at lower wages violates the principle of equal pay for equal work, agroindustries with monopolies can deliberately and with impunity hire women at lower wages than men. In general, when women are hired in industries the nature of their employment is precarious, frequently being of a casual and seasonal nature and in greatest demand during peak periods. In an effort to understand the implications of industrialization for African women a global perspective is necessary, for at present the incorporation of the African women in direct industrialization is minimal. Racism has played an important role in the exploitation of the African continent, and no serious study of class and gender inequality in Africa can overlook that important fact. Numerous studies have shown how industry perpetuates the sexual division of labor. Even in the industrialized nations, women often have held the least paid and most precarious jobs in industry. Women's vulnerability is further worsened by several factors, the most obvious being their reproductive capabilities. In addition to being more vulnerable to industrial hazards, their employment can be truncated by

    Securing Online Banking transactions for customer is the primary goal of financial institutions that provides Internet banking facility. Mobile phones play an important role in our society as more and more functions having been integrated within mobile phones, such as Internet browsing, mobile banking, and shopping. Mobiles phones can be used to secure ATM card pins by sending to the customer directly rather than in emails or by other means which has a possibility of hacking. In this paper we have proposed method of generating a Private Key Security Token by bank authentication servers which uses IMSI registers and IMEI number of client's mobile registered. The key is generated by implementing RIPE MD160 and Hex Encode Algorithm. Token received is valid only for that client mobile only and can be generated upon request by customer dynamically. The client is given a PIN and a Master Key when registered to the Online Banking Services. If in case a client's mobile is lost, authentication is done using Unique Master Key, else the Private Key Token is used there by making transactions secured and simple without the need of carrying any USB Tokens. The additional functionality provides the client more security on their transactions. Due to this Phishing attacks by the hackers is avoided.

    Using data from Malawi, this study situates the discourse on migration, entrepreneurship, and development within the context of Africa’s social realities. It examines self-employment differences among three groups of migrants and corresponding group differences in agricultural and non-agricultural self-employment. International migrants are found to be more engaged in self-employment than internal-migrants. However, our results suggest that previous findings on the development-related contributions of returning migrants from the West need to be appropriately contextualized. When returnees from the West invest in self-employment, they typically shy away from Africa’s largest economic sector - agriculture. In contrast, levels of self-employment, especially in agricultural self-employment, are highest among returning migrants and immigrants from other African countries, especially from those nearby. We also underscore the gendered dimensions of migrants’ contribution to African development by demonstrating that female migrants are more likely to be self-employed in agriculture than male migrants. Furthermore, as human-capital increases, migrants are more likely to concentrate their self-employment activities in non-agricultural activities and not in the agricultural sector. The study concludes by using these findings to discuss key implications for policy and future research. PMID:25598569

    Parameters were described for spatial database to facilitate drought monitoring and famine early warning in the African Sahel. The proposed system, referred to as the African Drought and Famine Information System (ADFIS) is ultimately recommended for implementation with the NASA/FEMA Spatial Analysis and Modeling System (SAMS), a GIS/Dymanic Modeling software package, currently under development. SAMS is derived from FEMA'S Integration Emergency Management Information System (IEMIS) and the Pacific Northwest Laborotory's/Engineering Topographic Laboratory's Airland Battlefield Environment (ALBE) GIS. SAMS is primarily intended for disaster planning and resource management applications with the developing countries. Sources of data for the system would include the Developing Economics Branch of the U.S. Dept. of Agriculture, the World Bank, Tulane University School of Public Health and Tropical Medicine's Famine Early Warning Systems (FEWS) Project, the USAID's Foreign Disaster Assistance Section, the World Resources Institute, the World Meterological Institute, the USGS, the UNFAO, UNICEF, and the United Nations Disaster Relief Organization (UNDRO). Satellite imagery would include decadal AVHRR imagery and Normalized Difference Vegetation Index (NDVI) values from 1981 to the present for the African continent and selected Landsat scenes for the Sudan pilot study. The system is initially conceived for the MicroVAX 2/GPX, running VMS. To facilitate comparative analysis, a global time-series database (1950 to 1987) is included for a basic set of 125 socio-economic variables per country per year. A more detailed database for the Sahelian countries includes soil type, water resources, agricultural production, agricultural import and export, food aid, and consumption. A pilot dataset for the Sudan with over 2,500 variables from the World Bank's ANDREX system, also includes epidemiological data on incidence of kwashiorkor, marasmus, other nutritional deficiencies, and

    We investigate the role of deeply-rooted pre-colonial ethnic institutions in shaping comparative regional development within African countries. We combine information on the spatial distribution of ethnicities before colonization with regional variation in contemporary economic performance, as proxied by satellite images of light density at night. We document a strong association between pre-colonial ethnic political centralization and regional development. This pattern is not driven by differences in local geographic features or by other observable ethnic-specific cultural and economic variables. The strong positive association between pre-colonial political complexity and contemporary development obtains also within pairs of adjacent ethnic homelands with different legacies of pre-colonial political institutions.

    Due to the current unavailability of vaccines or treatments for African swine fever (ASF), which is caused by African swine fever virus (ASFV), rapid and reliable detection of the virus is essential for timely implementation of emergency control measures and differentiation of ASF from other swine diseases with similar clinical presentations. Here, an improved PCR assay was developed and evaluated for sensitive and universal detection of ASFV. Primers specific for ASFV were designed based on the highly conserved region of the vp72 gene sequences of all ASFV strains available in GenBank, and the PCR assay was established and compared with two OIE-validated PCR tests. The analytic detection limit of the PCR assay was 60 DNA copies per reaction. No amplification signal was observed for several other porcine viruses. The novel PCR assay was more sensitive than two OIE-validated PCR assays when testing 14 strains of ASFV representing four genotypes (I, V, VIII and IX) from diverse geographical areas. A total of 62 clinical swine blood samples collected from Uganda were examined by the novel PCR, giving a high agreement (59/62) with a superior sensitive universal probe library-based real-time PCR. Eight out of 62 samples tested positive, and three samples with higher Ct values (39.15, 38.39 and 37.41) in the real-time PCR were negative for ASFV in the novel PCR. In contrast, one (with a Ct value of 29.75 by the real-time PCR) and two (with Ct values of 29.75 and 33.12) ASFV-positive samples were not identified by the two OIE-validated PCR assays, respectively. Taken together, these data show that the novel PCR assay is specific, sensitive, and applicable for molecular diagnosis and surveillance of ASF.

  13. Enhanced Bank-Stability Modeling With Coupled Geotechnical, Hydraulic and Near-Bank Groundwater Sub-Models: Development and Validation

    2008-12-01

    Physically-based, deterministic bank-stability models have recently been developed to effectively simulate the driving and resisting forces governing streambank erosion. Significant advances have been made in the manner in which groundwater flow through variably saturated porous media, planar and circular geotechnical failures and fluvial sediment transport are simulated. However, to date, coupling these models has required tedious exporting and conversion of geometries and results and manual remeshing. In this presentation, we introduce the first fully integrated suite of models that deterministically simulate the controlling hydrologic, hydraulic and geotechnical processes that govern streambank erosion and channel-width adjustment. The model suite incorporates routines that: 1. Permit the user to enter between 5 and 23 points to describe the bank cross-sectional geometry; 2. Automatically generate a mesh by which to implicitly discretize the 2-D Richards equation utilizing finite volumes. The resulting pentadiagonal matrix is solved iteratively with Stone's Strongly Implicit Procedure (SIP). Timesteps are automatically adjusted to minimize mass balance and truncation errors; 3. Evaluate the force-equilibrium factor of safety (Fs), permitting the simulation of planar and cantilever shear failures with a horizontal slice method and planar shear failures with tension cracks with a rigorous vertical slice method. A random walk approach is adopted to search for the minimum Fs; 4. Estimate the increase in cohesion due to vegetation with a global load-sharing Fibre Bundle Model; and 5. Simulate the erosion of the bank face and bank toe with an excess shear stress approach. Management options to increase slope stability (through the addition of vegetation) and reduce channel- boundary erodibility (through the addition of natural and artificial structures) are also incorporated. We illustrate the efficacy of the modeling approach with a series of case studies in which

    Few research studies with non-English-speaking audiences have been conducted to explore community members' views on biospecimen donation and banking, and no validated Spanish-language multi-scale instruments exist to measure community perspectives on biobanking. This study describes the development and psychometric properties of the Biobanking Attitudes aNd Knowledge Survey-Spanish (BANKS-SP). The BANKS was translated into Spanish using the Brislin method of translation. Draft BANKS-SP items were refined through cognitive interviews, and psychometric properties were assessed in a sample of 85 Spanish-speaking individuals recruited at various community events in a three county area in central west Florida, USA. The final BANKS-SP includes three scales: attitudes, knowledge, and self-efficacy; as well as three single items, which evaluated receptivity and intention to donate a biospecimen for research. The final Cronbach's alpha coefficients for the two scales that use a Likert response format indicated adequate internal consistency (attitudes, α = .79; self-efficacy, α = .91). Intention to donate blood and intention to donate urine were positively correlated with attitudes, self-efficacy, and receptivity to learning more about biobanking (all p's < .001). BANKS-SP-Knowledge was not statistically significantly correlated with other BANKS-SP scales or single items measuring intention to donate a biospecimen for research and receptivity for learning more about biospecimen research. The BANKS-SP attitudes and self-efficacy scales show evidence of satisfactory reliability and validity. Additional research should be conducted with larger samples to assess the BANKS-SP instrument's reliability and validity. A valid and reliable Spanish-language instrument measuring Spanish-speaking community members' views about biobanking may help researchers evaluate relevant communication interventions to enhance understanding, intention, and actual biospecimen donation

  1. Bank accretion and the development of vegetated depositional surfaces along modified alluvial channels

    Hupp, C.R.; Simon, A.

    1991-01-01

    This paper describes the recovery of stable bank form and development of vegetated depositional surfaces along the banks of channelized West Tennessee streams. Most perennial streams in West Tennessee were straightened and dredged since the turn of the century. Patterns of fluvial ecological responses to channelization have previously been described by a six-stage model. Dendrogeomorphic (tree-ring) techniques allowed the determination of location, timing, amount, and rate of bank-sediment deposition. Channel cross sections and ecological analyses made at 101 locations along 12 streams, encompassing bends and straight reaches, show that channel and bank processes initially react vertically to channelization through downcutting. A depositional surface forms on banks once bed-degradation and heightened bank mass wasting processes have eased or slowed. The formation of this depositional surface marks the beginning of bank recovery from channelization. Dominating lateral processes, characteristic of stable or natural channels, return during the formation and expansion of the depositional surface, suggesting a relation with thalweg deflection, point-bar development, and meanderloop extension. Characteristic woody riparian vegetation begins to grow as this depositional surface develops and becomes part of the process and form of restabilizing banks. The depositional surface initially forms low on the bank and tends to maintain a slope of about 24??. Mean accretion rates ranges from 5.9 cm/yr on inside bends to 0 cm/yr on most outside bends; straight reaches have a mean-accretion rate of 4.2 cm/yr. The relatively stable, convex upward, depositional surface expands and ultimately attaches to the flood plain. The time required for the recovery process to reach equilibrium averaged about 50 years. Indicative pioneer speccies of woody riparian vegetation include black willow, river birch, silver maple, and boxelder. Stem densities generally decrease with time after and

    Human transcription error is an acknowledged risk when extracting information from paper records for entry into a database. For a tissue bank, it is critical that accurate data are provided to researchers with approved access to tissue bank material. The challenges of tissue bank data collection include manual extraction of data from complex medical reports that are accessed from a number of sources and that differ in style and layout. As a quality assurance measure, the Breast Cancer Tissue Bank (http:\\\\www.abctb.org.au) has implemented an auditing protocol and in order to efficiently execute the process, has developed an open source database plug-in tool (eAuditor) to assist in auditing of data held in our tissue bank database. Using eAuditor, we have identified that human entry errors range from 0.01% when entering donor's clinical follow-up details, to 0.53% when entering pathological details, highlighting the importance of an audit protocol tool such as eAuditor in a tissue bank database. eAuditor was developed and tested on the Caisis open source clinical-research database; however, it can be integrated in other databases where similar functionality is required.

  3. Understanding African American Adolescents’ Identity Development: A Relational Developmental Systems Perspective

    PubMed Central

    Brittian, Aerika S.

    2012-01-01

    This article examines the development of African American adolescents’ identity using a relational developmental systems theory framework, which led to the expectation that identity development is linked to both the reduction of risk behaviors and the promotion of African American adolescents’ healthy development. Different personological theories of identity development were discussed, including Erikson’s theory of psychosocial development and Marcia’s theory of identity statuses. Developmental systems theory was used to further the literature on African American adolescents’ identity development, by integrating various views of identity development as they pertain to these youth. Furthermore, the formation of many aspects of identity may be an important coping and resilience process for such youth. In addition, directions for future research are discussed, including a consideration of the complexity of diversity that exists within the African American adolescent population, and a call for more longitudinal assessments of identity development is presented.

  4. Variation in enamel development of South African fossil hominids.

    2006-12-01

    Dental tissues provide important insights into aspects of hominid palaeobiology that are otherwise difficult to obtain from studies of the bony skeleton. Tooth enamel is formed by ameloblasts, which demonstrate daily secretory rhythms developing tissue-specific structures known as cross striations, and longer period markings called striae of Retzius. These enamel features were studied in the molars of two well known South African hominid species, Australopithecus africanus and Paranthropus robustus. Using newly developed portable confocal microscopy, we have obtained cross striation periodicities (number of cross striations between adjacent striae) for the largest sample of hominid teeth reported to date. These data indicate a mean periodicity of seven days in these small-bodied hominids. Important differences were observed in the inferred mechanisms of enamel development between these taxa. Ameloblasts maintain high rates of differentiation throughout cervical enamel development in P. robustus but not in A. africanus. In our sample, there were fewer lateral striae of Retzius in P. robustus than in A. africanus. In a molar of P. robustus, lateral enamel formed in a much shorter time than cuspal enamel, and the opposite was observed in two molars of A. africanus. In spite of the greater occlusal area and enamel thickness of the molars of both fossil species compared with modern humans, the total crown formation time of these three fossil molars was shorter than the corresponding tooth type in modern humans. Our results provide support for previous conclusions that molar crown formation time was short in Plio-Pleistocene hominids, and strongly suggest the presence of different mechanisms of amelogenesis, and thus tooth development, in these taxa.

  6. A new model for developing and executing culturally appropriate behavior modification clinical trials for African Americans.

    PubMed

    2003-01-01

    Past clinical trials addressing behavior modification for cardiovascular disease (CVD) prevention have not been culturally appropriate for African Americans. This supposition is borne out by the continued challenges researchers face not only in recruiting and retaining African Americans in clinical trials, but also in achieving the desired outcomes among this population. Investigators have limited resources to develop culturally appropriate CVD prevention trials. The scientific literature reveals 2 models for implementing culturally appropriate interventions applicable to CVD prevention among African Americans; however, these models are not easily applied to the clinical trial setting. We propose a new model for developing a culturally appropriate clinical trial. The clinical trial is a function of the investigator's cultural framework, meaning that an investigator will have more difficulty designing clinical trials appropriate for use with cultures other than his or her own, a definite limitation when attempting to effectively reach diverse populations. Differences between the cultural frameworks of most clinical trials and African Americans' cultural frameworks lead to intrinsic biases, limiting the ability of African Americans to achieve the desired outcomes for any particular trial. An African-American participant's degree of immersion in traditional African-American culture, or acculturation, influences the magnitude of these biases. Investigators must be aware of, and attempt to mitigate, such biases so that the trial's potential for success is equitable across ethnic groups. In addition, investigators must understand how to effectively address relevant biases of African Americans without challenging their ethnic identity. Steps to decrease biases are described.

    2011-01-01

    Don't Ask, Don't Tell is gaining attention in family studies literature as a cultural specific context to understand lesbian, gay, and bisexual visibility in African-American families and communities. This policy suggests that sexual minorities are accepted within African-American families and communities as long as they do not label themselves or acknowledge publicly that they engage in same-sex relationships. The narratives of two African-American lesbians (aged 26 and 27 years) are chronicled in the present study to reveal their lesbian identity development, lesbian identity management, and how they defined and navigated Don't Ask, Don't Tell. They encountered challenges and successes in a quest to find communities that would embrace and affirm their multiple marginalized identities. Their stories are offered as a point of entry to further inquiry concerning African-American lesbian visibility and identity proclamation within African-American families and communities.

    In 1994 AEF signed a Cooperative Agreement with DOE to address a program called the African Power /Energy and Environmental Development Plan. The Program initially addressed five area: (1) Historical Black Colleges and Universities Energy/Environmental Program; (2) The Department of Energy and United States Private Industry Africa Program; (3) The Annual United States Energy Study Tour; (4) South African Training Program, and (5) South African Environmental Program. The programs were implemented in conjunction with DOE, institutions, agencies and the private sector support in the USA and within African nations. AEF has worked with government and technical representatives from 13 African nations and expanded the program to address sponsorship of South African students in Historical Black Colleges and Universities, supporting DOE trade missions through participation and planning, and giving presentations in the U.S., and Africa regarding business opportunities in the African energy sector. The programs implemented have also opened doors for the US private sector to seek business opportunities in Africa and for African nations to gain exposure to US products and services.

    Purpose To elucidate barriers and facilitators related to glaucoma medication adherence among African Americans (AA) with glaucoma and to elicit input from a community-based participatory research team in order to guide the development of a culturally informed, health promotion program for improving glaucoma medication adherence among AA’s. Methods The nominal group technique (NGT), a highly structured focus group methodology, was implemented with 12 separate groups of AA’s patients with glaucoma (N = 89) to identify barriers and facilitators related to glaucoma medication usage. Participant rank-ordering votes were summed across groups and categorized into themes. Next, an individually and culturally targeted health promotion program promoting appropriate medication adherence was developed based on focus group results and input from a community-based participatory research team. Results The top five barriers included problems with 1) forgetfulness, 2) side effects, 3) cost/affordability, 4) eye drop administration, and 5) the eye drop schedule. The most salient top five facilitators were 1) fear or thoughts about the consequences of not taking eye drops, 2) use of memory aids, cues, or strategies, 3) maintaining a regular routine or schedule for eye drop administration, 4) ability to afford eye drops, and 5) keeping eye drops in the same area. The resulting health promotion program was based on a multi-component empowerment framework that included glaucoma education, motivational interviewing, and problem-solving training to improve glaucoma medication adherence. Conclusions Barriers and facilitators related to glaucoma medication adherence among AA’s are multifactorial. Based on the NGT themes and input from the community-based participatory research team, a culturally informed, health promotion program was designed and holds great promise for improving medication adherence among this vulnerable population.

    This study examined dimensionality and item-level psychometric properties of an item bank measuring activities of daily living (ADL) across inpatient rehabilitation facilities and community living centers. Common person equating method was used in the retrospective veterans data set. This study examined dimensionality, model fit, local independence, and monotonicity using factor analyses and fit statistics, principal component analysis (PCA), and differential item functioning (DIF) using Rasch analysis. Following the elimination of invalid data, 371 veterans who completed both the Functional Independence Measure (FIM) and minimum data set (MDS) within 6 days were retained. The FIM-MDS item bank demonstrated good internal consistency (Cronbach's α = .98) and met three rating scale diagnostic criteria and three of the four model fit statistics (comparative fit index/Tucker-Lewis index = 0.98, root mean square error of approximation = 0.14, and standardized root mean residual = 0.07). PCA of Rasch residuals showed the item bank explained 94.2% variance. The item bank covered the range of θ from -1.50 to 1.26 (item), -3.57 to 4.21 (person) with person strata of 6.3. The findings indicated the ADL physical function item bank constructed from FIM and MDS measured a single latent trait with overall acceptable item-level psychometric properties, suggesting that it is an appropriate source for developing efficient test forms such as short forms and computerized adaptive tests.

    How effectively has the World Bank Group assisted its clients in enhancing the contribution of the extractive industries to sustainable development? (Extractive industries include oil, gas, and mining of minerals including coals and metals.) This evaluation finds that with its global mandate and experience, comprehensive country development focus, and overarching mission to fight poverty, the World Bank Group is well positioned to help countries overcome the policy, institutional, and technical challenges that prevent them from transforming resource endowments into sustainable benefits. Furthermore, the World Bank Group's achievements are many. On the whole, its extractive industries projects have produced positive economic and financial results, though compliance with its environmental and social safeguards remains a challenge. Its research has broadened and deepened understanding of the causes for the disappointing performance of resource-rich countries. Its guidelines for the mitigation of adverse environmental and social impacts have been widely used and appreciated. More recently, it has begun to address the challenge of country governance with a variety of instruments. The World Bank Group can, however, do much to improve its performance in enhancing the extractive industry sector's contribution to sustainable development and poverty reduction. The report identifies three main areas for improvement - formulating an integrated strategy, strengthening implementation and engagement of stakeholders. 5 annexes.

    1997-09-01

    10 southern hemisphere countries (Bangladesh, Colombia, Egypt, Kenya, Indonesia, Morocco, Mexico, Thailand, Tunisia, and Zimbabwe) have created a new international initiative known as the "Partnership in Population and Development." The principal objective is to create a more effective mechanism for developing countries to share their experiences through technical assistance and south-south coordination. The 10 countries have developed population and family planning programs over the past 2 decades with the support of the Rockefeller Foundation, World Bank, and UN Population Fund. The Partnership in Population and Development is directed by an Administrative Council composed of representatives from each country, who are generally the highest officials in the area of reproductive health and family planning. The First African Meeting for South-South Cooperation in Reproductive Health/Family Planning and Population, held in Tunis in July 1997, was organized in collaboration with the Secretariat of the partnership and with the participation of representatives of 12 French-speaking African countries and of several international organizations. The meeting allowed the participants to express their opinions concerning the principles of the South-South Partnership and the practical mechanisms that would allow it to facilitate exchanges of information and experiences between African countries.

    The measurement of pain behavior is a key component of the assessment of persons with chronic pain; however few self-reported pain behavior instruments have been developed. We developed a pain behavior item bank as part of the Patient Reported Outcome Measurement Information System (PROMIS). For the Wave I testing, because of the large number of PROMIS items, a complex sampling approach was used where participants were randomly assigned to either respond to two full item banks or to multiple 7-item blocks of items. A web-based survey was designed and completed by 15,528 members of the general population and 967 individuals with different types of chronic pain. Item response theory (IRT) analysis models were used to evaluate item characteristics and to scale both items and individuals on the pain behavior domain. The pain behavior item bank demonstrated good fit to a unidimensional model (Comparative Fit Index = 0.94). Several iterations of IRT analyses resulted in a final 39 item pain behavior bank, and different IRT models were fit to the total sample and to those participants who experienced some pain. The results indicated that these items demonstrated good coverage of the pain behavior construct. Pain behavior scores were strongly related to pain intensity and moderately related to self-reported general health status. Mean pain behavior scores varied significantly by groups based on pain severity and general health status. The PROMIS pain behavior item bank can be used to develop static short-form and dynamic measures of pain behavior for clinical studies. PMID:19683873

  7. Clean energy for development investment framework: the World Bank Group action plan

    SciTech Connect

    2007-03-06

    In September 2005 the Development Committee requested the World Bank to develop an Investment Framework for Clean Energy and Development - in the context of the Gleneagles Communique on Climate Change, Clean Energy and Sustainable Development which was issued in July 2005. This Action Plan provides an update of work undertaken to date as well as actions planned by the World Bank Group (WBG) in support of the Clean Energy for Development Investment Framework (CEIF). The Action Plan relies on partnerships, including with the International Financial Institutions (IFIs) and the private sector. While it concentrates on maximizing and extending existing instruments, it provides for continued dialogue with governments and the private sector on new approaches to accelerate the transition to a low carbon economy. In addition to increased investments, the private sector has an important role to play in closing the investment gap in many countries. Projects such as Bujagali (Uganda), Nam Theun II (Laos) and China and India Thermal Power Plant Rehabilitation projects are examples of how partnerships with the private sector can work, both on financing but also on enhancing the overall regulatory framework for enhanced partnerships. The report was prepared for the 15 April 2007 Development Committee meeting, a joint committee of the Board of Governors of the World Bank and the International Monetary Fund on the transfer of real resources to developing countries. 3 figs., 3 tabs., 5 annexes.

    Background Faith-based mental health interventions developed and implemented using a community-based participatory research (CBPR) approach hold promise for reaching rural African Americans and addressing health disparities. Objectives To describe the development, challenges, and lessons learned from the Trinity Life Management, a faith-based stress management intervention in a rural African American faith community. Methods The researchers used a CBPR approach by partnering with the African American faith community to develop a stress management intervention. Development strategies include working with key informants, focus groups, and a community advisory board (CAB). Results The community identified the key concepts that should be included in a stress management intervention. Conclusions The faith-based “Trinity Life Management” stress management intervention was developed collaboratively by a CAB and an academic research team. The intervention includes stress management techniques that incorporate Biblical principles and information about the stress–distress–depression continuum. PMID:26548794

    Because existing risk prediction models for lung cancer were developed in white populations, they may not be appropriate for predicting risk among African-Americans. Therefore, a need exists to construct and validate a risk prediction model for lung cancer that is specific to African-Americans. We analyzed data from 491 African-Americans with lung cancer and 497 matched African-American controls to identify specific risks and incorporate them into a multivariable risk model for lung cancer and estimate the 5-year absolute risk of lung cancer. We performed internal and external validations of the risk model using data on additional cases and controls from the same ongoing multiracial/ethnic lung cancer case-control study from which the model-building data were obtained as well as data from two different lung cancer studies in metropolitan Detroit, respectively. We also compared our African-American model with our previously developed risk prediction model for whites. The final risk model included smoking-related variables [smoking status, pack-years smoked, age at smoking cessation (former smokers), and number of years since smoking cessation (former smokers)], self- reported physician diagnoses of chronic obstructive pulmonary disease or hay fever, and exposures to asbestos or wood dusts. Our risk prediction model for African-Americans exhibited good discrimination [75% (95% confidence interval, 0.67−0.82)] for our internal data and moderate discrimination [63% (95% confidence interval, 0.57−0.69)] for the external data group, which is an improvement over the Spitz model for white subjects. Existing lung cancer prediction models may not be appropriate for predicting risk for African-Americans because (a) they were developed using white populations, (b) level of risk is different for risk factors that African-American share with whites, and (c) unique group-specific risk factors exist for African-Americans. This study developed and validated a risk prediction

    To serve African-American families effectively, marriage and family therapists need to develop a level of cultural competence. This content analysis of the relevant treatment literature was conducted to examine the most common expert recommendations for family therapy with African Americans. Fifteen specific guidelines were generated, including orient the family to therapy, do not assume familiarity, address issue of racism, intervene multi-systemically, do home visits, use problem-solving focus, involve religious leader, incorporate the father, and acknowledge strengths. Conceptual and empirical support for each guideline is discussed, and conclusions are made regarding culturally competent therapy with African-American families.

    Ozdzeński, W; Mystkowska, E T

    1976-06-01

    The development of the bank vole Clethrionomys glareolus is described from implantation to the formation of the foetal membranes. The embryonic development of this species combines features of primitive rodent species, for example Geomys bursarius and highly specialized ones, for examples Mus musculus. The egg-cylinder is formed by invagination into the blastocoelic cavity of the inner cell mass and polar trophoblast overlying it; this resembles in many respects the early stages of development of primitive species. The fully formed egg-cylinder, however, resembles that of the mouse and the formation of foetal membranes is also similar to that in Muridae. It is concluded that in the bank vole and also in other rodents, the extra-embryonic ectoderm of the egg-cylinder is derived from the polar trophoblast rather than from the inner cell mass.

    A conceptual model of the morphological development of the riparian margins of newly cut river channels is presented, suggesting early feedbacks between vegetation growth and bank form. To test the model, observations of long and cross profiles, bank sediment and seed deposition, and bank vegetation development were collected over the first 2 years of river flows through a reach of the River Cole, West Midlands, UK. The newly created channel had a sinuous planform and varying asymmetric trapezoidal cross section in sympathy with the planform. No imposed bedforms or bank reseeding were included in the design. Over the 2 years, development of bedforms was rapid, with bed sediment sorting and bank profile adjustment occurring more steadily and progressively. Six classes of bank profile were identified by the end of the study period, illustrating close associations with sediment aggradation, vegetation colonization, and growth patterns. Vegetation colonization of the banks was seeded predominantly from local sources during the summer and from hydrochory (transport by the river) during the winter. Colonizing vegetation on the riverbanks appeared to act as a significant propagule source by the second summer and as an increasingly important roughness element, trapping both propagules and sediment, within the second year and providing early feedback into bank evolution. As a result, the time required for riparian margin development in the conceptual model was found to be considerably longer than observed in the study river. In addition, the role of surface wash/bank failure in modifying the bank profile and transporting seeds onto the upper bank face during the first year of bank development was found to be important in initiating rapid bank vegetation colonization and surface stabilization. This set of processes had not been incorporated in the initial conceptual model. In relation to channel restoration, this research illustrates that in small temperate rivers of modest

    The goal of this paper is to present an overview of new tools that can be used to further our understanding of phonological development and disorders. We begin with a summary of the field of child phonology with a focus on databases and methods of analysis and then move to a description of PhonBank, a shared database for the study of phonology, and Phon, a specialised software system capable of performing various types of phonological analyses based on both phonetic transcriptions and acoustic analyses of speech productions. We provide a detailed example of using PhonBank and Phon to examine the use of velar fronting using longitudinal data from one child with typical development and three children with phonological disorder. We conclude with an emphasis on data sharing and its central relevance to further advances in our field. PMID:26035223

    PubMed Central

    2010-01-01

    Africa's progress depends on her capacity to generate, adapt, and use scientific knowledge to meet regional health and development needs. Yet, Africa's higher education institutions that are mandated to foster this capacity lack adequate resources to generate and apply knowledge, raising the need for innovative approaches to enhance research capacity. In this paper, we describe a newly-developed program to support PhD research in health and population sciences at African universities, the African Doctoral Dissertation Research Fellowship (ADDRF) Program. We also share our experiences implementing the program. As health research capacity-strengthening in Africa continues to attract attention and as the need for such programs to be African-led is emphasized, our experiences in developing and implementing the ADDRF offer invaluable lessons to other institutions undertaking similar initiatives.

    2016-01-01

    The African American church has promoted the health of African Americans through supporting interventions that target a wide variety of diseases, and it is a crucial community partner in the development of HIV prevention interventions. Although research has described the development of church-based HIV interventions, there is a significant lack of frameworks and approaches available to guide the implementation and maintenance of HIV interventions within church-based settings. A developing framework of a comprehensive church-based intervention, derived from an ethnographic study about the development, implementation, and maintenance of an HIV/AIDS Ministry within an African American church is presented. This approach can provide guidance to support the development, implementation, and maintenance of HIV interventions in faith settings. PMID:25702738

    Objective To develop a comprehensive, psychometrically sound, and conceptually grounded patient reported outcomes (PRO) measurement system for individuals with spinal cord injury (SCI). Methods Individual interviews (n = 44) and focus groups (n = 65 individuals with SCI and n = 42 SCI clinicians) were used to select key domains for inclusion and to develop PRO items. Verbatim items from other cutting-edge measurement systems (i.e. PROMIS, Neuro-QOL) were included to facilitate linkage and cross-population comparison. Items were field tested in a large sample of individuals with traumatic SCI (n = 877). Dimensionality was assessed with confirmatory factor analysis. Local item dependence and differential item functioning were assessed, and items were calibrated using the item response theory (IRT) graded response model. Finally, computer adaptive tests (CATs) and short forms were administered in a new sample (n = 245) to assess test-retest reliability and stability. Participants and Procedures A calibration sample of 877 individuals with traumatic SCI across five SCI Model Systems sites and one Department of Veterans Affairs medical center completed SCI-QOL items in interview format. Results We developed 14 unidimensional calibrated item banks and 3 calibrated scales across physical, emotional, and social health domains. When combined with the five Spinal Cord Injury – Functional Index physical function banks, the final SCI-QOL system consists of 22 IRT-calibrated item banks/scales. Item banks may be administered as CATs or short forms. Scales may be administered in a fixed-length format only. Conclusions The SCI-QOL measurement system provides SCI researchers and clinicians with a comprehensive, relevant and psychometrically robust system for measurement of physical-medical, physical-functional, emotional, and social outcomes. All SCI-QOL instruments are freely available on Assessment CenterSM. PMID:26010963

    Erosional landforms of the gully type include among others V-shaped dissections in high shores of water bodies or steep slopes of large river valleys in various morphoclimatic zones (Drozdowski 1977; Gawrysiak 1994; Burkard, Kostaschuk 1997; Smolska 2007; Leyland, Darby 2008; Superson, Zagórski 2008; Repelewska-Pękalowa et al. 2013). Such erosional dissections, known as bank gullies, develop as a result of concentrated overland flow caused by intensive precipitation or snowmelt. They are usually ephemeral landforms reaching insignificant sizes in natural conditions. They can exceptionally develop during one event and as a result of increased rate of erosion caused by agricultural activities (Rodzik et. al. 2004, 2011; Rodzik, Terpiłowski 2005). An accelerated development of bank gullies is also observed in the zone of artificial dam reservoirs (Pecherkin 1969; Ovchinnikov et al. 1999). In the area of the Kamsk Reservoir, an increase in the volume of gullies developed in loess-like sediments is 2-3 times higher than shore degradation by abrasion processes (Pecherkin 1969). Gully erosion is also an important source of material deposited in the slope zone and in water bodies (Vandekerckhove et al. 2001; Poesen et al. 2003; Foster et al. 2007). The high number and various stages of development of bank gullies dissecting the southern shores of the Bratsk Reservoir encouraged undertaking studies on the rate of development and evolution of these landforms (Ovchinnikov et al. 1999; Mazaeva et al. 2006, 2014; Grobelska et al. 2007; Kaczmarek et al. 2012). High seasonal and annual water level fluctuations in dam reservoirs provide conditions for development of the described gully landforms substantially different than those occurring in the zone of marine shores, lakes, or river valleys. The primary objective of the study was the determination of the current conditions and the identification of factors responsible for the development of gullies in the coastal zone of the

  5. The value of banked samples for oncology drug discovery and development.

    Shaw, Peter M; Patterson, Scott D

    2011-01-01

    To gain insights into human biology and pathobiology, ready access to banked human tissue samples that encompass a representative cross section of the population is required. For optimal use, the banked human tissue needs to be appropriately consented, collected, annotated, and stored. If any of these elements are missing, the studies using these samples are compromised. These elements are critical whether the research is for academic or pharmaceutical industry purposes. An additional temporal element that adds enormous value to such banked samples is treatment and outcome information from the people who donated the tissue. To achieve these aims, many different groups have to work effectively together, not least of which are the individuals who donate their tissue with appropriate consent. Such research is unlikely to benefit the donors but others who succumb to the same disease. The development of a large accessible human tissue bank resource (National Cancer Institute's Cancer HUman Biobank [caHUB]) that provides an ongoing supply of human tissue for all working toward the common goal of understanding human health and disease has a number of advantages. These include, but are not limited to, access to a broad cross section of healthy and diseased populations beyond what individual collections may achieve for understanding disease pathobiology, therapeutic target discovery, as well as a source of material for diagnostic assay validation. Models will need to be developed to enable fair access to caHUB under terms that enable appropriate intellectual property protection and ultimate data sharing to ensure that the biobank successfully distributes samples to a broad range of researchers.

    1997-06-01

    Condom use for HIV prevention has been very inconsistent in most sub-Saharan African countries. Studies from around the continent report that knowledge about HIV transmission is variable and seems to be related to gender, socioeconomic and educational status. There is a large body of psychological knowledge about HIV prevention which has been applied to condom promotion campaigns in developed countries. These approaches to condom promotion, based on formal theory, have not been used on a wide scale in African countries and this paper explores ways in which psychological theory might be appropriately applied in a situation of high HIV prevalence.

    African swine fever virus is a large DNA virus which can cause an acute haemorrhagic fever in pigs resulting in high mortality. No vaccine is available, limiting options for control. The virus encodes up to 165 genes and virus particles are multi-layered and contain more than 50 proteins. Pigs immunised with natural low virulence isolates or attenuated viruses produced by passage in tissue culture and by targeted gene deletions can be protected against challenge with virulent viruses. CD8+ cells are required for protection induced by attenuated strain OURT88/3. Passive transfer of antibodies from immune to naïve pigs can also induce protection. Knowledge of the genome sequences of attenuated and virulent strains and targeted gene deletions from virulent strains have identified a number of virus genes involved in virulence and immune evasion. This information can be used to produce rationally attenuated vaccine strains. Virus antigens that are targets for neutralising antibodies have been identified and immunisation with these recombinant proteins has been shown to induce partial protection. However knowledge of antigens which encode the dominant protective epitopes recognised by CD8+ T cells is lacking.

    Prior clinical research supports the effectiveness of cancer support groups for cancer patients and their families, yet African-American families continue to be underrepresented in cancer support groups and in cancer clinical research studies. In order to fill this gap, we developed and evaluated a culturally adapted family support group for African-American families coping with parental cancer. We encountered unexpected challenges in overcoming barriers to recruitment, partnering with oncology providers, and building trust with the African-American community and African-American families coping with parental cancer. We describe actions taken during the two phases of this study and lessons learned along the way about recruiting and engaging African-American families in cancer support group studies, partnering with oncology providers, networking with the African-American community, and the importance of demonstrating cultural sensitivity to overcome the understandable historical legacy of mistrust.

    An atlas of Zimbabwe and the Southern African Development Community was designed and produced for use by American diplomats in Zimbabwe. Two copies of the bound atlas are used by the Embassy of the United States of America (U.S. Embassy) and the Mission of the U.S. Agency for International Development (USAID) in Harare, Zimbabwe, to orient visitors and discuss matters of diplomacy and development in Zimbabwe and the Southern African Development Community. The atlas contains maps derived from satellite images showing features of the physical geography of Southern Africa and Zimbabwe and plastic overlays showing rivers and lakes and manmade features, such as major roads, railroads, and cities. The atlas is an important tool that American diplomats can use to orient participants in discussions of the environment and to develop agreements for management of the environment in Zimbabwe and Southern Africa.

    Despite efforts to increase breast cancer screening (BCS) among African American women, disparities in breast cancer mortality persist. Culturally framed health communication may provide a useful strategy to address this issue. Spirituality not only represents an integral aspect of African American culture, but it has also been identified as a potential barrier to BCS among this population. Rather than continuing to focus on spirituality as a barrier, there is an opportunity to develop promotional messages that tap into the protective properties of spirituality among this population. The goals of this study were to engage a group of African American women to identify important spiritual elements to be included in health communication materials, and to subsequently develop a spiritually framed BCS message in response to their feedback. Three nominal group sessions were conducted with 15 African American women. Results revealed three important spiritual elements that can be incorporated into BCS health messages: (a) the body as a temple; (b) going to the doctor does not make you faithless; and (c) God did not give us the spirit of fear. These elements were used to draft a spiritually framed BCS message. Next, 20 face-to-face semistructured interviews were conducted to help finalize the spiritually framed BCS message for use in a future study on culturally framed health communication.

    Taylor, Kenneth J.

    This study examined the identity development for a sample of 90 African American undergraduate engineering male and female students attending an HBCU. Using the Student Development Task and Lifestyle Assessment (SDTLA), which is based on Chickering and Reisser's identity development theory, differences in identity development were examined with respect to gender, academic classification, and grade point average. Previous research has shown the need to look beyond academic factors to understand and influence the persistence of African American engineering students. Non-cognitive factors, including identity development have proven to be influential in predicting persistence, especially for African American engineering students. Results from the analysis revealed significant means for academic classification and five of the dependent variables to include career planning peer relations, emotional autonomy, educational involvement, and establishing and clarifying purpose. Post hoc analysis confirmed significant differences for four of those dependent variables. However, the analysis failed to confirm statistical significant differences in peer relations due to academic classification. The significant decline in the mean scores for development in these four areas, as students progressed from sophomore to senior year revealed strong implications for the need to provide programming and guidance for those students. Institutions of higher education should provide more attention to the non-cognitive areas of development as a means of understanding identity development and working toward creating support systems for students.

    Over the past few decades researchers have begun to examine the importance of understanding positive youth development and the many contexts in which youth find themselves. The social contexts in which adolescent development occurs are varied and complex, particularly the development among African American youth. African American youth are faced with a number of challenges including living in single-parent homes, high teen pregnancy rates, and poor neighborhoods, yet many of these youth continue to thrive. The purpose of this study was to examine the relationship between family structure (single-parenting) and adolescent outcomes such as educational aspirations and sexual activity among African American adolescent youth aged 12-17. Approximately 462 African American youth were surveyed. A number of positive results emerged; for instance, there was a negative correlation between family structure and educational aspirations. The number of parents in the home did not interfere with youth wanting to complete high school and go on to college (r = - .218, r² = .04, p < .05). The results also showed that as educational aspirations increased, the number of sexual partners decreased (r = - .141, meaning that the more adolescents reported a desire to complete high school, they were less likely to report having sexual intercourse. These positive results should be promoted among African American youth so that those faced with these challenges will note that others have overcome and accomplished their goals. In this population educational aspirations were important. Limitations and future research are discussed.

    Because interventions developed in partnership with African American fathers not residing with their children are virtually non-existent, existing interventions fail to address the multiple factors that constrain these fathers’ positive involvement with their children. We developed a video tape fatherhood intervention: Building Bridges to Fatherhood. In collaboration with a Fathers Advisory Council composed of 12 African American fathers, we used Aranda’s framework for community-based nursing intervention development to design the intervention. Data from 13 focus group meetings show Advisory Council members’ insights on program structure and content, fathers’ commitment to their children and communities, and the benefits they garnered from Council participation. The implications for involving fathers in intervention development include using relevant language, vernacular, and interpersonal interactions. PMID:22685066

    EtherCAT (Ethernet for Control Automation Technology) is gaining wide spread popularity in the automation industry as a real time field bus based on low cost, Ethernet hardware. EtherCAT maximizes use of 100Mbps Ethernet hardware by using a collision free ring topology, efficient Ethernet frame utilization (> 95%), and data exchange "on the fly". These characteristics enable EtherCAT to achieve Master to Slave node data exchange rates of > 1000 Hz. The Green Bank Telescope, commissioned in 2000, utilizes an analog control system for motion control of 8 elevation and 16 azimuth motors. This architecture, while sufficient for observations at frequencies up to 50GHz, has significant limitations for the current scientific goals of observing at 115GHz. Accordingly, the Green Bank staff has embarked on a servo upgrade project to develop a digital servo system which accommodates development and implementation of advanced control algorithms. This paper describes how the new control system requirements, use of existing infrastructure and budget constraints led us to define a distributed motion control architecture where EtherCAT real-time Ethernet was selected as the communication bus. Finally, design details are provided that describe how NRAO developed a custom EtherCAT-enabled motor controller interface for the GBT's legacy motor drives in order to provide technical benefits and flexibility not available in commercial products.

    In 2013 Canadian Blood Services (CBS) launched the National Public Cord Blood Bank (NPCBB), a program to collect, process, test, and store cord blood units donated for use in transplantation. A key component of the creation of the NPCBB is the establishment of a program that enables cord blood not suitable for banking or transplantation to be used for biomedical research purposes. Along with the development of processes and policies to manage the NPCBB and the cord blood research program, CBS-in collaboration with researchers from the Stem Cell Network-have also developed educational tools to provide relevant information for target audiences to aid implementation and operation. We describe here one of these tools, the REB Primer on Research and Cord Blood Donation (the Primer), which highlights key ethical and legal considerations and identifies Canadian documents that are relevant to the use of cord blood in biomedical research. The Primer also introduces the NPCBB and describes the systems CBS is implementing to address ethical issues. The Primer is intended to assist research ethics boards in evaluating the ethical acceptability of research protocols, to facilitate harmonized decision-making by providing a common reference, and to highlight the role of research ethics boards in governance frameworks. With the Primer we hope to illustrate how the development of such educational tools can facilitate the ethical implementation and governance of programs related to stem cell research in Canada and abroad.

    Background The social valorisation of overweight in African populations could promote high-risk eating behaviours and therefore become a risk factor of obesity. However, existing scales to assess body image are usually not accurate enough to allow comparative studies of body weight perception in different African populations. This study aimed to develop and validate the Body Size Scale (BSS) to estimate African body weight perception. Methods Anthropometric measures of 80 Cameroonians and 81 Senegalese were used to evaluate three criteria of adiposity: body mass index (BMI), overall percentage of fat, and endomorphy (fat component of the somatotype). To develop the BSS, the participants were photographed in full face and profile positions. Models were selected for their representativeness of the wide variability in adiposity with a progressive increase along the scale. Then, for the validation protocol, participants self-administered the BSS to assess self-perceived current body size (CBS), desired body size (DBS) and provide a “body self-satisfaction index.” This protocol included construct validity, test-retest reliability and convergent validity and was carried out with three independent samples of respectively 201, 103 and 1115 Cameroonians. Results The BSS comprises two sex-specific scales of photos of 9 models each, and ordered by increasing adiposity. Most participants were able to correctly order the BSS by increasing adiposity, using three different words to define body size. Test-retest reliability was consistent in estimating CBS, DBS and the “body self-satisfaction index.” The CBS was highly correlated to the objective BMI, and two different indexes assessed with the BSS were consistent with declarations obtained in interviews. Conclusion The BSS is the first scale with photos of real African models taken in both full face and profile and representing a wide and representative variability in adiposity. The validation protocol proved its

    Hominid evolution, specifically the split of the hominid-chimpansee lineages in the late Miocene has long been hypothesized to be linked to the retreat of the tropical rainforest in Africa in the late Miocene. A main cause for the climatic and vegetation change often considered was uplift of Africa but also uplift of the Himalaya and the Tibetan Plateau was suggested to have contributed to an intensification of the African-Asian monsoon system and hence impacted rainfall distribution over Eastern Africa. In contrast, more recent proxy data suggest that open grassland habitats were available to human ancestors and apes long before their divergence and that there is no evidence for a closed rainforest in the late Miocene. We use the coupled global circulation model CCSM3 with an online coupled dynamic vegetation module to investigate the impact of the uplift processes on the African-Asian monsoon circulation and consequent changes in tropical African vegetation. The model is run with a resolution of T85 (~1.4°) for the atmosphere and land surface and a variable resolution for the computation of ocean and sea ice down to a meridional grid spacing of 0.3° around the equator. We performed a set of sensitivity experiments, altering elevations of the Himalaya and the Tibet Plateau and of East and South Africa separately and in combination from half to full present day level. The simulations confirm the dominant impact of the East and South African uplift for climate and vegetation development of the African tropics. Only a weak, but significant, impact of the prescribed Asian Uplift on African monsoon and vegetation development could be detected. Himalaya/Tibet Plateau uplift lead to slightly dryer conditions in Central Africa and small increases in rainfall over East Africa. According to the model simulations topographic uplift of Africa significantly altered rainfall in Central Africa, which coincides with proxy records from the Congo basin showing a change towards

    Multibeam sonar mapping and geophysical and geological groundtruth surveys were coupled with tidal current and sediment transport model calculations to investigate the sediment transport and formation processes of the complex seabed features off the Cape Split headland in the upper Bay of Fundy. The Cape Split banner bank, composed of coarse to very coarse sand, is a southwest-northeast oriented, large tear-drop shaped sand body with superimposed sand waves that show wavelengths from 15 to 525 m and heights from 0.5 to 19 m. Isolated and chains of barchan dunes occur on top of a shadow bank to the southeast of the banner bank. The barchan dunes are composed of well-sorted medium sand and are oriented northwest-southeast. Their mean height and width are 1.5 and 55 m, respectively. A gravel bank, with an elongated elliptical shape and west-east orientation, lies in the Minas Passage erosional trough east of the headland to form the counterpart to the sandy Cape Split banner bank. The southern face is featureless but the northern face is covered by gravel megaripples. Tidal model predictions and sediment transport calculations show that the formation of the banner bank and the gravel bank are due to the development of the transient counter-clockwise and clockwise tidal eddies respectively to the west and east of the headland. The formation of barchan dunes is controlled by the nearly unidirectional flow regime in outer Scots Bay. Sand waves on the flanks of the Cape Split banner bank show opposite asymmetry and the barchan dunes are asymmetric to the northeast. The tidal current and sediment transport predictions corroborate bedform asymmetry to show that sand wave migration and net sediment transport is to southwest on the northern flank of the banner bank but to northeast on the southern bank. Long-term migration of the Scots Bay barchan dunes is to the northeast. Spring-condition tidal currents can cause frequent mobilization and high-stage transport over the

    This work presents a Biological Resource Bank generated as a complementary supporting tool for the reproduction and the in situ and ex situ conservation of the Iberian lynx. In its design we prioritized the preservation of a maximum of the current genetic and biological diversity of the population, and the harmless collection of the samples. To provide future reproductive opportunities through any possible technique, we processed and cryopreserved germinal cells and tissues from dead animals, 7 males and 6 females, as well as somatic cells and tissues from 69 different individuals. This somatic cell reserve reflects a very important fraction of the population biodiversity which, furthermore, will allow the development of a wide variety of studies that can be easily extrapolated to the majority of the population. We have developed a new non-destructive method to isolate cells with stem-cell-like properties. If considered convenient in the future, and after proper research, such cells could permit therapeutic applications and perhaps be a good source to be used in somatic cell nuclear transfer. Samples of whole blood and its derivatives, hairs, urine and feces from many different individuals were also preserved. Proper storage of such samples is required to allow epidemiological studies to be performed for the testing of different etiological hypotheses or, in general, to develop any bio-sanitary study to improve conservation strategies within the natural habitat. This work describes the main aspects involved in the practical implementation of the Iberian lynx Biological Resource Bank, as a model that could be useful for the development of similar banks for other endangered species.

    Premise of the study: Microsatellites were designed and characterized in the African timber forest tree Terminalia superba (Combretaceae). Due to their high variability, these markers are suitable to investigate gene flow patterns and the structure of genetic diversity. Methods and Results: From a genomic library obtained by next-generation sequencing, seven monomorphic and 14 polymorphic microsatellite loci were developed. The polymorphic microsatellites displayed two to 27 alleles (mean 11.4; expected heterozygosity range 0.283–0.940, mean 0.736) in one population from southeastern Cameroon. Genotypes were typical of an outbreeding diploid species, although null alleles explain a significant heterozygote deficit in three loci. Cross-amplification in three congeneric species (T. ivorensis, T. avicennioides, and T. mantaly) failed, suggesting that T. superba is rather divergent. Conclusions: This set of newly developed microsatellite markers will be useful for assessing the genetic diversity, population structure, and demographic history of T. superba in tropical African forests.

    Having an HIV ministry within a church depends on the religious culture of that church. However, little is known about how a church’s religious culture influences an HIV ministry. This study’s purpose was to examine how an African American church’s religious culture supported the development, implementation, and maintenance of an HIV ministry within the church. An ethnographic case study research design was used. Data were collected through interviews, non-participant and participant observations, review of pertinent documents, and survey of congregants. Results revealed the following as important for an HIV ministry: (a) a belief in helping others and treating everyone with respect and dignity, (b) feelings of compassion toward individuals infected with HIV, and (c) HIV education. This information can assist in developing interventions to enhance the African American church movement toward HIV ministries. PMID:22212914

    As one of the largest marathons worldwide, the Bank of America Chicago Marathon (BACCM; Chicago, Illinois USA) accumulates high volumes of data. Race organizers and engaged agencies need the ability to access specific data in real-time. This report details a data visualization system designed for the Chicago Marathon and establishes key principles for event management data visualization. The data visualization system allows for efficient data communication among the organizing agencies of Chicago endurance events. Agencies can observe the progress of the race throughout the day and obtain needed information, such as the number and location of runners on the course and current weather conditions. Implementation of the system can reduce time-consuming, face-to-face interactions between involved agencies by having key data streams in one location, streamlining communications with the purpose of improving race logistics, as well as medical preparedness and response.

    Ectomycorrhizal fungal (EMF) propagules play an important role in seedling establishment following disturbance. However, little is known about how the EMF propagule community changes with forest development. In this study, EMF propagules were examined using seedling bioassays in rhizosphere soils collected from a recently closed Pb-Zn tailing (Taolin Pb-Zn tailing (TLT)), a Cu tailing (Dexing Cu No. 2 tailing (DXT)) that had undergone 21 years of restoration, and a mature Masson pine (Pinus massoniana) forest (DXC) outside the Cu mining areas. The corresponding EMF communities colonizing Masson pine at each site were also investigated for comparison. After 8 months of running bioassays, ectomycorrhizal colonization was poor for seedlings grown in TLT (9.0 % ± 14.9 %) and DXT soils (22.4 % ± 17.7 %), while DXC seedlings were well colonized (47.5 % ± 24.9 %). Internal transcribed spacer sequencing revealed that EMF species richness increased with forest development in both the propagule bank (TLT, 6; DXT, 7; DXC, 12) and in the field (TLT, 8; DXT, 14; DXC, 26), though richness was lower in propagule banks. Several lineages, such as Cenococcum, Rhizopogon, Inocybe, Suillus, and Atheliaceae, were frequently encountered in propagule communities, but species assemblages were different among the three sites. Canonical correspondence analysis revealed that several soil parameters, i.e., N, EC, Cu, Pb, Zn, etc., were responsible for the distribution of EMF in the field and bioassay seedlings. The highest overlap in EMF species composition between the propagule bank and the field community was observed at the recently closed tailing (Morisita-Horn similarity = 0.71 for TLT), whereas the lowest overlap occurred at the mature forest (0.26 for DXC). These results indicate that EMF propagules in soil are less frequent and diverse in early primary succession and become more frequent and diverse along forest development, due mainly to the accumulation of

    Inge, Jillian

    The purpose of this phenomenological study was to examine how the construct of mentoring by African American males can support the academic development of African American male students. Since African American male students perform significantly lower in academic subjects than their counterparts of other ethnicities, there is an exigent need for change in this area. Built upon the conceptual framework of communal interactions and identity, the inquiry questioned the experiences of mentors for African American male secondary students, and their perceptions of the influence of a mentoring relationship when the mentor and mentee are of similar backgrounds. Participants in this study were 7 African American males who had mentored or were currently mentoring African American male students. Data, obtained through semi structured interviews and focus group interviews, were coded for themes that reflected the experiences of mentors in mentoring African American males. Mentors in this study reported that students with whom they share similar backgrounds and experiences were better able to relate to them than those who had dissimilar backgrounds and experiences. In addition, mentors reported their mentees were more likely to envision themselves in professional areas beyond their perceived cultural norm when they routinely interact with successful African American males from various fields; thus, it was important for mentors to provide opportunities for students to interact with professionals. Contributions to social change will emerge as African American male mentors understand and employ their roles as a fundamental component in the academic development of African American male secondary students and thus empower this population of students to achieve academic success and to serve in a capacity that nurtures their immediate surroundings.

    We report on recent findings of a fruitful research agenda that explores the importance of ethnic-specific traits in shaping African development. First, using recent surveys from Sub-Saharan African countries, we document that individuals identify with their ethnic group as often as with the nation pointing to the salience of ethnicity. Second, we focus on the various historical and contemporary functions of tribal leaders (chiefs) and illustrate their influence on various aspects of the economy and the polity. Third, we elaborate on a prominent dimension of ethnicity, that of the degree of complexity of pre-colonial political organization. Building on insights from the African historiography, we review recent works showing a strong association between pre-colonial centralization and contemporary comparative development both across and within countries. We also document that the link between pre-colonial political centralization and regional development -as captured by satellite images of light density at night-is particularly strong in areas outside the vicinity of the capitals, where due to population mixing and the salience of national institutions ethnic traits play a lesser role. Overall, our evidence is supportive to theories and narratives on the presence of a “dual” economic and institutional environment in Africa. PMID:27011760

  10. Institutional development: from legal pluralism to institutional bricolage in West African pastoralism.

    Pastoralists in Africa are increasingly vulnerable to the effects of globalisation, climate change and changes in land use. They are confronted with problems related to access to scarce natural resources and their regulation, the management of mobility, and too little investment in health systems, livestock production and social service delivery. However, this paper focuses on positive trends and vital innovations in pastoral societies. These rely on robust institutions and policy frameworks that contribute to economically secure, politically stable, and environmentally sustainable livelihoods for African pastoral societies. The authors analyse ways in which internal and external efforts can improve the economic viability and social aspects of pastoralism. The institutions that manage natural resources and their effects on livelihoods and access to social services must be critically reviewed. The authors suggest that a new model for the economic and social development of African pastoralism should be positioned between donor- or governmentdriven development (in other words, 'seeing like a state') and the autonomous development goals of pastoralists ('seeing like a pastoralist'). Pastoralists are resourceful, entrepreneurial and innovative people, fully able to support new institutional systems and services which recognise their way of life and production systems. It seems evident that African pastoralism will maintain its vitality and creativity through a process of 'bricolage', with institutional and policy innovations based on a constant renegotiation of norms, the reinvention or transformation of tradition, the importance of legitimate authority and the role of the people themselves in shaping such arrangements.

  11. African land ecology: opportunities and constraints for agricultural development.

    Voortman, Roelf L; Sonneveld, Ben G J S; Keyzer, Michiel A

    2003-08-01

    Compared to other continents, the economic growth performance of Sub-Saharan Africa has been poor over the last four decades. Likewise, progress in agricultural development has been limited and the Green Revolution left Africa almost untouched. The question raised in the literature is whether the poor performance is a question of poor policies or of an unfavorable biophysical environment (policy versus destiny). This paper, with a broad perspective, analyzes adaptation of current land use to environmental conditions in Africa and compares the physical resource base of Africa with Asia. In doing so, we search for unifying principles that can have operational consequences for agricultural development. We argue that some specificities of the natural resource base, namely local homogeneity and spatial diversity of the predominant Basement Complex soils, imply that simple fertilizer strategies may not produce the yield increases obtained elsewhere.

    African Americans with diabetes have a higher rate of lower-extremity amputation due to diabetic foot complications than the general public. Education about proper foot care can help prevent serious diabetic foot complications and assist in early detection of problems. The purpose of this project was to develop, formatively evaluate, and pilot test a self-care, take-home program for the prevention of foot problems in African Americans with diabetes. The program included a brief, one-on-one orientation session and a take-home foot self-care packet. Through telephone follow-up subjects reported the following: good to excellent overall rating of the program, favorable reactions to the patient instruction booklet, an overwhelming positive response to the large hand mirror, and a positive effect on their daily foot-care practices. The Afrocentricity of the patient education materials was preferred by younger subjects; older subjects found this approach too restrictive.

    We describe the development, feasibility, and acceptability of a novel preventive intervention for depression in African American girls living in urban poverty. Our approach targeted individual and interpersonal vulnerabilities that have been shown to confer risk for depression in samples of African American girls living in low-income, urban settings, including suppression of negative emotion and lack of assertiveness with peers, memory for positive emotion, active coping, and family connection. Focus groups and an open trial were conducted to refine the goals and mechanisms for skill building. A randomized controlled trial (RCT) of the new program (Cities Mother-Daughter Project) was conducted with 3rd-5th grade students from Chicago Public Schools (CPS). Three cycles of screening, randomization, and deployment were conducted to assess feasibility, satisfaction, and usability. Results indicate that feasibility was weak; whereas, satisfaction and usability were high. Future directions for testing efficacy are discussed.

    Focus groups with African American women who had experienced a breast biopsy were conducted during the process of "getting ready" for a breast biopsy educational study in which the intervention's educational materials and study instruments were developed and pre-tested. Recommendations were made for revising the breast biopsy educational booklet. As a result of the focus group discussions, changes were made in several of the graphics, the design and size of the booklet, and the tone of the piece. In addition, language describing the biopsy procedure was further simplified. The outcomes of this study were culturally tailored study materials to be used in an educational intervention to prepare African American women undergoing a breast biopsy procedure.

    In this paper we describe the development a culturally targeted (CT) smoking cessation intervention for low-to-middle income African–American smokers. Based on theoretically based guidelines, modifications were made to a standard treatment manual for group-based smoking cessation counseling that incorporates cognitive-behavioral, motivational, and twelve step skills. Approximately 41% of the standard treatment materials were modified, and four new modules were developed. A pilot study was conducted to compare acceptability, feasibility and early outcome indicates in African American smokers randomized to the CT intervention compared with existing data from African American smokers treated using a non-targeted standard approach (ST). Outcomes from the CT pilot study were promising: results showed high levels of feasibility, acceptability and better adherence to nicotine replacement therapy, higher quit rates, and better retention and follow-up compared with the ST. Findings suggest that a culturally targeted and intensive group based smoking cessation treatment is plausibly effective in improving smoking cessation outcomes in African American smokers, warranting a larger randomized trial.

    Mantle cell lymphoma (MCL) is a rare B-cell malignancy that carries a relatively poor prognosis compared to other forms of non-Hodgkin lymphoma. Standardized preclinical tools are desperately required to hasten the discovery and translation of promising new treatments for MCL. Via an initiative organized through the Mantle Cell Lymphoma Consortium and the Lymphoma Research Foundation, we gathered MCL cell lines from laboratories around the world to create a characterized MCL Cell Bank at the American Type Culture Collection (ATCC). Initiated in 2006, this collection now contains eight cell lines, all of which have been rigorously characterized and are now stored and available for distribution to the general scientific community. We believe the awareness and use of these standardized cell lines will decrease variability between investigators, harmonize international research efforts, improve our understanding of the pathogenesis of the disease and hasten the development of novel treatment strategies.

  2. Development of small carbonate banks on the south Florida platform margin: Response to sea level and climate change

    2003-01-01

    Geophysical and coring data from the Dry Tortugas, Tortugas Bank, and Riley’s Hump on the southwest Florida margin reveal the stratigraphic framework and growth history of these carbonate banks. The Holocene reefs of the Dry Tortugas and Tortugas Bank are approximately 14 and 10 m thick, respectively, and are situated upon Pleistocene reefal edifices. Tortugas Bank consists of the oldest Holocene corals in the Florida Keys with earliest coral recruitment occurring at ∼9.6 cal ka. Growth curves for the Tortugas Bank reveal slow growth (<1 mm/yr) until 6.2 cal ka, then a rapid increase to 3.4 mm/yr, until shallow reef demise at ∼4.2 cal ka. Coral reef development at the Dry Tortugas began at ∼6.4 cal ka. Aggradation at the Dry Tortugas was linear, and rapid (∼3.7 mm/yr) and kept pace with sea-level change. The increase in aggradation rate of Tortugas Bank at 6.2 cal ka is attributed to the growth of the Dry Tortugas reefs, which formed a barrier to inimical shelf water. Termination of shallow (<15 m below sea level) reef growth at Tortugas Bank at ∼4.2 cal ka is attributed to paleoclimate change in the North American interior that increased precipitation and fluvial discharge. Reef growth rates and characteristics are related to the rate of sea-level rise relative to the position of the reef on the shelf margin, and are additionally modified by hydrographic conditions related to climate change.

  3. Empirical development of brief smoking prevention videotapes which target African-American adolescents.

    1995-07-01

    Two studies are described which provide evaluations for two brief videotapes developed as supplemental materials in the prevention of tobacco use among African-American adolescents. One videotape (the "soap opera") provides a more general audience-oriented presentation of prevention material and it was filmed primarily at a shopping mall, whereas the other videotape (the "rap") provides a "hip-hop generation" presentation, and it was filmed primarily at an outdoor hangout. The first study compared the two videotapes against each other. The second study compared the two videotapes combined in the same presentation, controlling for order of presentation, against a discussion group control. The results of the two studies indicated few differences in receptivity to the two videotapes among primarily African-American and Latino young adolescents. The rap videotape was rated as more accurate in its depiction of the African-American lifestyle, although both videotapes were equally liked. When shown together, the videotapes were not found to be superior in decreasing behavioral intention to smoke compared to a discussion group control. No change in trial of smoking was observed within or across conditions measured over a pre-post summer interval. These data suggest that "culturally sensitive" videotapes have no more of a short-term effect on youth than do other types of brief interventions which involve minority implementers.

    African American males experience poor academic performance, high absenteeism at school, and are at increased risk of being involved in violence than other racial groups. Given that the educational outlook for African American males appears bleak, it is important to assess the aspirations of these adolescent males in order to find the gap between aspirations and educational attainment. In order to promote positive development within this population, it is essential that factors that affect African American males be identified. A survey was administered to male students attending elementary, middle, and high schools in a local school district. A cross-sectional study was conducted to examine the career and educational aspirations of African American males. A total of 473 males were surveyed: 45% African American, 22% Caucasian, 13% biracial, and 19% Other (including Asian American, Hispanic, Native American). The results revealed that African American males aspired to attend college at the same rate as other ethnic groups. Also, African American males were more likely to aspire to be professional athletes than males from other ethnic groups. Important factors to consider when designing a program are discussed as well as future research and limitations.

  6. How developments in cryobiology, reproductive technologies and conservation genomics could shape gene banking strategies for (farm) animals.

    Many local breeds are currently at risk because of replacement by a limited number of specialized commercial breeds. Concurrently, for many breeds, allelic diversity within breeds declines because of inbreeding. Gene banking of germplasm may serve to secure the breeds and the alleles for any future use, for instance to recover a lost breed, to address new breeding goals, to support breeding schemes in small populations to minimize inbreeding, and for conservation genetics and genomics research. Developments in cryobiology and reproductive technology have generated several possibilities for preserving germplasm in farm animals. Furthermore, in some mammalian and bird species, gene banking of material is difficult or impossible, requiring development of new alternative methods or improvement of existing methods. Depending on the species, there are interesting possibilities or research developments in the use of epididymal spermatozoa, oocytes and embryos, ovarian and testicular tissue, primordial germ cells, and somatic cells for the conservation of genetic diversity in farm- and other animal species. Rapid developments in genomics research also provide new opportunities to optimize conservation and sampling strategies and to characterize genome-wide genetic variation. With regard to gene banks for farm animals, collaboration between European countries is being developed through a number of organizations, aimed at sharing knowledge and expertise between national programmes. It would be useful to explore further collaboration between countries, within the framework of a European gene banking strategy that should minimize costs of conservation and maximize opportunities for exploitation and sustainable use of genetic diversity.

    Mesoscale convective systems (MCSs) in West Africa traverse strong thermodynamic gradients during their westward propagation from land to ocean. Some of the systems continue to develop after crossing the coastline and may ultimately develop into tropical cyclones, while others do not. Understanding the lifecycle behavior of these convective systems and the factors that contribute to their continuous development as they transition from a continental environment to a marine environment poses a challenge. We examine the difference between two MCSs, one that continued to develop when it crossed the West African coast and one that did not, using European Centre for Medium-Range Weather Forecasts (ECMWF) Re-Analysis (ERA Interim) and Tropical Rainfall Measurement Mission (TRMM) 3B42 data. The non-developing MCS that intensified briefly while over land, weakened as soon as it crossed the coast. Preliminary results show that the developing MCS interacted with two cyclonic vortices, one associated with an African Easterly Wave that was propagating towards the coast and the other vortex generated by the topography near the coast.

  8. Rotenone Decreases Hatching Success in Brine Shrimp Embryos by Blocking Development: Implications for Zooplankton Egg Banks

    2016-01-01

    While many zooplankton species recover quickly after the treatment of water resources with the piscicide, rotenone, some fail to reach pretreatment population density or, in rare cases, do not reappear at all. The variable impact of rotenone on zooplankton populations could stem from differences in the capacity of species to switch entirely to anaerobic catabolic pathways in the presence of rotenone, which blocks mitochondrial electron transport. Alternatively, variable responses among species could originate from differences in permeability of dormant life-stages to lipophilic chemicals like rotenone. The purpose of the present study was to determine the effects of rotenone on development, emergence and hatching of zooplankton embryos that lack both the anaerobic capacity to develop in the presence of rotenone and a permeability barrier to prevent the entry of rotenone during dormancy. Post-diapause embryos of the brine shrimp, Artemia franciscana, were employed as a model system, because they are permeable to lipophilic compounds when dechorionated and require aerobic conditions to support development. Early development in this species is also well characterized in the literature. Brine shrimp embryos were exposed to rotenone while development was either slowed by chilling or suspended by anoxia. Development, emergence and hatching were then observed in rotenone-free artificial seawater. The data presented demonstrate that rotenone freely diffuses across the embryonic cuticle in a matter of hours, and prevents development and emergence after brief exposures to ecologically relevant concentrations (0.025–0.5 mg L-1) of the piscicide. Neither the removal of rotenone from the environment, nor the removal of embryonic water with a hypertonic solution, are sufficient to reverse this block on development and emergence. These data indicate that rotenone could impair recruitment from egg banks for species of zooplankton that lack both an embryonic barrier to the entry

    In the photo, employees of the UAB Bank, Knoxville, Tennessee, are using Teller Transaction Terminals manufactured by SCI Systems, Inc., Huntsville, Alabama, an electronics firm which has worked on a number of space projects under contract with NASA. The terminals are part of an advanced, computerized financial transaction system that offers high efficiency in bank operations. The key to the system's efficiency is a "multiplexing" technique developed for NASA's Space Shuttle. Multiplexing is simultaneous transmission of large amounts of data over a single transmission link at very high rates of speed. In the banking application, a small multiplex "data bus" interconnects all the terminals and a central computer which stores information on clients' accounts. The data bus replaces the maze-of wiring that would be needed to connect each terminal separately and it affords greater speed in recording transactions. The SCI system offers banks real-time data management through constant updating of the central computer. For example, a check is immediately cancelled at the teller's terminal and the computer is simultaneously advised of the transaction; under other methods, the check would be cancelled and the transaction recorded at the close of business. Teller checkout at the end of the day, conventionally a time-consuming matter of processing paper, can be accomplished in minutes by calling up a summary of the day's transactions. SCI manufactures other types of terminals for use in the system, such as an administrative terminal that provides an immediate printout of a client's account, and another for printing and recording savings account deposits and withdrawals. SCI systems have been installed in several banks in Tennessee, Arizona, and Oregon and additional installations are scheduled this year.

    The health impact of environmental toxins has gained increasing recognition over the years. Polycyclic aromatic hydrocarbons (PAHs) and environmental tobacco smoke (ETS) are known to affect nervous system development in children, but no studies have investigated how polymorphisms in PAH metabolic or detoxification genes affect child cognitive development following PAH exposure during pregnancy. In two parallel prospective cohort studies of nonsmoking African American and Dominican mothers and children in New York City and of Caucasian mothers and children in Krakow, Poland, we explored the effect of gene-PAH interaction on child mental development index (MDI), as measured by the Bayley Scales of Infant Development-Revised (BSID-II). Genes known to play important roles in the metabolic activation or detoxification of PAHs were selected. Genetic variations in these genes could influence susceptibility to adverse effects of PAHs in polluted air. We explored the effects of interactions between prenatal PAH exposure and 21 polymorphisms or haplotypes in these genes on MDI at 12, 24, and 36 months among 547 newborns and 806 mothers from three different ethnic groups: African Americans, Dominicans, and Caucasians. PAHs were measured by personal air monitoring of mothers during pregnancy. Significant interaction effects between haplotypes and PAHs were observed in mothers and their newborns in all three ethnic groups after Bonferroni correction for multiple comparisons. The strongest and most consistent effect observed was between PAH and haplotype ACCGGC of the CYP1B1 gene. PMID:19860743

    Development is a complex phenomenon that concerns all the structures and subsystems of a society, affecting its quantitative aspects through economic growth and its qualitative aspects through social and cultural change. Planning is needed, but it is effective only to the extent that it is applied to a known and controllable reality. The integration of population and development is still a poorly defined concept despite the fat the it has been a topic of interest for the past several decades. at least since the 1946 creation of the UN Population Commission. Development planning should begin with evaluation of the past and present economic, social, and demographic situation of the country and should include formulation of clear objectives. The Central African Republic is a hugh country with some significant resources but a fragile and underdeveloped economy. The population, estimated at nearly 3 million, is very unevenly distributed, with 1/2 million living in the capital of Bangui. Fertility and mortality are high. The Central African Republic has had multi year development plans since 1948, but they have largely consisted of collections of projects funded by external investment. In the absence of institutional mechanisms capable of defining priorities and strategies leading to concrete decisions, the plans remained excessively general and ambitious. Economic planning has improved somewhat over the years, but there is still a lack of basic economic and social data, a shortage of financial resources, and inadequate mechanisms for setting priorities and strategies for decision making. No mechanism has been developed for integrating population and development although some research and family planning activities have been undertaken. A 1980 national seminar on problems of development was attended by representatives of all sectors, and in 1981 a national team formulated guidelines for a new strategy of social development. Family planning services were added to the

    Despite increases in obesity and related diseases in developing nations, initial refugee clinical visits do not address these issues. We explored the development of obesity and related diseases in a longitudinal prospective cohort of African refugees resettling in northeastern US. Using state Department of Health data, refugees were linked to a health system. Body mass index, diabetes, hypertension, and hyperlipidemia status were extracted from charts. US regional controls from NAMCS/NHAMCS data were matched by age, sex, race, and visit year. African refugee BMI increased after resettlement at 1 (1.7 ± 2.9, p < 0.0001) and 5 years (3.1 ± 3.7, p < 0.0001), a different trend than matched regional controls (p = 0.01). Refugees had increased rates of diabetes (1.0 vs. 10.8 %, p < 0.0001), hypertension (16.7 vs. 21.6 %, p < 0.0001) and hyperlipidemia (3.9 vs. 10.8 %, p < 0.0001) at 5 years not observed in regional controls. Our findings emphasize the need for interventions during resettlement to prevent development of obesity and related disease in this vulnerable population.

  1. Text Messaging to Improve Hypertension Medication Adherence in African Americans: BPMED Intervention Development and Study Protocol

    PubMed Central

    Artinian, Nancy T; Schwiebert, Loren; Yarandi, Hossein; Levy, Phillip D

    2015-01-01

    Background Hypertension (HTN) is a major public health concern in the United States, with almost 78 million Americans age 20 years and over suffering from the condition. Moreover, HTN is a key risk factor for health disease and stroke. African Americans disproportionately shoulder the burdens of HTN, with greater prevalence, disease severity, earlier onset, and more HTN-related complications than age-matched whites. Medication adherence for the treatment of HTN is poor, with estimates indicating that only about half of hypertensive patients are adherent to prescribed medication regimens. Although no single intervention for improving medication adherence has emerged as superior to others, text message medication reminders have the potential to help improve medication adherence in African Americans with uncontrolled HTN as mobile phone adoption is very high in this population. Objective The purpose of this two-phased study was to develop (Phase I) and test in a randomized controlled trial (RCT) (Phase II) a text message system, BPMED, to improve the quality of medication management through increasing medication adherence in African Americans with uncontrolled HTN. Methods In Phase I, we recruited 16 target end-users from a primary care clinic, to assist in the development of BPMED through participating in one of three focus groups. Focus groups sought to gain patient perspectives on HTN, medication adherence, mobile phone use, and the use of text messaging to support medication adherence. Potential intervention designs were presented to participants, and feedback on the designs was solicited. In Phase II, we conducted two pilot RCTs to determine the feasibility, acceptability, and preliminary efficacy of BPMED in primary care and emergency department settings. Both pilot studies recruited approximately 60 participants, who were randomized equally between usual care and the BPMED intervention. Results Although data collection is now complete, data analysis from the

    The re-colonization or recovery of grass species after disappearance due to heavy grazing depends on the presence of persistent soil seed banks that might be accumulated over time from the aboveground vegetation. Moreover, successful plant recruitment is a function of seed production, seed germination and seedling survival, which can be mechanistically understood through studying the life cycle processes of grass species populations under field conditions. Therefore, we studied the number of germinable seeds, species richness and life-forms in the soil seed banks under light and heavy grazing conditions, and the changes in grass species populations in a semi-arid savanna of Ethiopia. Accordingly, a total of 103 species (15 perennial and 29 annual grasses, 6 legumes, 52 forbs and 1 woody species) emerged from the soil samples collected. Lightly grazed sites had a higher seed density compared with heavily grazed sites. The seed density increased over the first three months of soil sampling and decreased thereafter. Perennial grasses dominated the light grazing sites, whereas annual species dominated the heavily grazed sites, indicating that perennial grasses were replaced by annual species in the soil seed bank through grazing. The mean mortality rate from the seedling stage to adult plants was 65%. The seed-to-seedling stage was found to be the most critical transitional stage for grass survival. High seedling mortality in the aboveground vegetation and depletion of seeds in the soil seed banks as a result of sustained heavy grazing can lead to local extinction and disappearance of perennial grasses in semi-arid Ethiopian savannas.

    New prevention options are urgently needed for African-Americans in the United States given the disproportionate impact of HIV/AIDS on this group. This combined with recent evidence supporting the efficacy of computer technology-based interventions in HIV prevention led our research group to pursue the development of a computer-delivered individually tailored intervention for heterosexually active African-Americans—the tailored information program for safer sex (TIPSS). In the current article, we discuss the development of the TIPSS program, including (i) the targeted population and behavior, (ii) theoretical basis for the intervention, (iii) design of the intervention, (iv) formative research, (v) technical development and testing and (vi) intervention delivery and ongoing randomized controlled trial. Given the many advantages of computer-based interventions, including low-cost delivery once developed, they offer much promise for the future of HIV prevention among African-Americans and other at-risk groups.

    Pollen substitute diets are a valuable resource for maintaining strong and health honey bee colonies. Specific diets may be useful in one region or country and inadequate or economically unviable in others. We compared two artificial protein diets that had been formulated from locally-available ingredients in Brazil with bee bread and a non-protein sucrose diet. Groups of 100 newly-emerged, adult workers of Africanized honey bees in Brazil and European honey bees in the USA were confined in small cages and fed on one of four diets for seven days. The artificial diets included a high protein diet made of soy milk powder and albumin, and a lower protein level diet consisting of soy milk powder, brewer's yeast and rice bran. The initial protein levels in newly emerged bees were approximately 18-21 µg/µL hemolymph. After feeding on the diets for seven days, the protein levels in the hemolymph were similar among the protein diet groups (~37-49 µg/µL after seven days), although Africanized bees acquired higher protein levels, increasing 145 and 100% on diets D1 and D2, respectively, versus 83 and 60% in the European bees. All the protein diets resulted in significantly higher levels of protein than sucrose solution alone. In the field, the two pollen substitute diets were tested during periods of low pollen availability in the field in two regions of Brazil. Food consumption, population development, colony weight, and honey production were evaluated to determine the impact of the diets on colony strength parameters. The colonies fed artificial diets had a significant improvement in all parameters, while control colonies dwindled during the dearth period. We conclude that these two artificial protein diets have good potential as pollen substitutes during dearth periods and that Africanized bees more efficiently utilize artificial protein diets than do European honey bees.

    Background There are differences in cancer-risk perception among racial/ethnic groups that may affect health risk behaviors. Methods Using a community partnered-participatory research approach, we conducted a survey on cancer screening, risk behaviors, and related knowledge/attitudes within 11 churches in South Los Angeles with predominantly African-American parishioners. This analysis examines correlates of perceived risk of developing cancer among 755African American adults. Results Almost 15% of participants indicated higher perceived risk for cancer compared to the average man/woman of the same age, 38% indicated same risk, whereas 48% perceived lower risk. Sixty-nine individuals (9%) reported a cancer history and 63% reported at least one blood relative with cancer. Controlling for demographic characteristics and healthcare access, participants who reported higher risk of cancer had higher level of cancer-related knowledge; were current and ex-smokers; had poorer health status; had a blood relative with cancer; had a cancer history; and had discussed their risk of cancer with their doctor. The bivariate association between high perceived cancer risk and lack of exercise and obesity disappeared after adjusting for demographic characteristics and perceived health status. Conclusions Our data suggest that a substantial proportion of African Americans in South Los Angeles may underestimate their cancer risk. Additionally, lack of exercise and obesity are not recognized as independent cancer risk factors as much as smoking and personal and family history of cancer. Next steps will be to inform participating churches about our findings and explore their interest in taking steps to reduce health risk behaviors among their parishioners. PMID:24026303

    Alarming increases in the incidence of hypertension in many low- and middle-income countries are related to alcohol overuse. It is unclear whether alcohol overuse is a symptom of psychological distress. The authors assessed psychological distress in Africans and its relationship with a 5-year change in blood pressure (BP), independent of alcohol intake. The authors followed 107 Africans with optimal BP (≤120/80 mm Hg) (aged 35-75 years) over 5 years. Alcohol intake (self-report and serum γ-glutamyl transferase) and nonspecific psychological distress (Kessler Screening Scale for Psychological Distress [K6]) were assessed. The K6 predicted hypertension development (P=.019), and its individual component "nervous" increased a participant's risk two-fold to become hypertensive (hazard ratio, 2.00 [1.23-3.26]). By entering K6 and γ-glutamyl transferase into multivariable-adjusted regression models for change in systolic BP, both were independently associated with change in systolic BP. Psychological distress and scoring high on being nervous predicted the development of hypertension over 5 years, independent of alcohol intake.

    2014-12-01

    Globally, transgenic or genetically modified (GM) crops are considered regulated products that are subject to regulatory oversight during trans-boundary movement, testing and environmental release. In Africa, regulations for transgenic crops are based on the outcomes of the historic Earth Summit Conference held in Rio, Brazil two decades ago, namely, the adoption of the Convention on Biological Diversity (CBD) and the subsequent adoption of the Cartagena Protocol on Biosafety. To exploit the potential benefits of transgenic crops while safeguarding the potential risks on human health and environment, most African countries have signed and ratified the CBD and the Cartagena Protocol on Biosafety. Consequently, these countries are required to take appropriate legal, administrative and other measures to ensure that the handling and utilization of living modified organisms are undertaken in a manner that reduces the risks to humans and the environment. These countries are also expected to provide regulatory oversight on transgenic crops through functional national biosafety frameworks (NBFs). While in principle this approach is ideal, NBFs in most African countries are steeped in a host of policy, legal and operational challenges that appear to be at cross-purposes with the noble efforts of seeking to access, test and deliver promising GM crops for use by resource-limited farmers in Africa. In this paper we discuss the regulatory challenges faced during the development and commercialization of GM crops based on experiences from countries in Sub-Saharan Africa.

    Foraminiferal, sedimentological, geophysical, and geochronologic data were utilized to elucidate the late Quaternary geologic development of the Croatan Beach Ridge Complex (CBRC), Bogue Sound, and Bogue Banks, North Carolina, USA. The CBRC is a relict beach ridge feature located on the mainland. It is separated from the modern barrier island, Bogue Banks, by Bogue Sound. Seventeen cores along shore-normal and shore-parallel transects provided material for sedimentologic and foraminiferal analysis and resulted in the recognition of seven depositional facies representing a variety of coastal depositional environments. Chronologic and depositional facies data suggest the CBRC was initiated during MIS 5a and rapid southward progradation produced a cape structure. Eolian reactivation of the upper sand of the CBRC occurred during the last glacial maximum (∼18 ka). The age of flood tide delta deposits in Bogue Sound suggests that the Holocene barrier island, Bogue Banks, had formed by ∼6 ka. Shoreface ravinement resulted in a shoreface landward of the present shoreline by ∼3.5 ka. Seaward and westward spit progradation of Bogue Banks began ∼1.7 ka and continued to ∼1.3 ka. Normal marine salinity conditions were present in Bogue Sound ∼1.1 ka, suggesting removal of at least the narrowest parts of the barrier island, coeval with a previously documented segmentation of the southern Outer Banks barrier islands. Previous work has linked this segmentation to climate warming and increased tropical storm activity during the Medieval Climate Anomaly. This study illustrates the complex response of this coastal system to Pleistocene and Holocene sea-level and climate change over two major sea-level cycles. In particular, the regional geomorphology during MIS5a and the Holocene sea-level highstand differ significantly and this, in large part, was controlled by the antecedent geologic framework, resulted in the contrasting more localized coastal geomorphic response.

    2008-12-01

    Health financing reforms in most low-income countries promote social and micro health insurance, in order to reduce direct spending by patients. Three phases of development can be distinguished in African countries: at first, schemes were developed only for the formal sector, then micro health insurance targeted the informal sector, and finally, health insurance was included in larger plans to reach universal coverage. The impact of health insurance is, as yet, difficult to assess. If beneficiaries have a better access to health services, the financing of health sector is not significantly improved, and there is no change in professional behaviour, in particular, in public facilities. In spite of their limits, social health insurance schemes continue to be implemented, but as a part of hybrid financing system, fitting with the abilities of low-income countries.

    Racism constitutes a significant risk to the healthy development of African American youth. Fortunately, however, not all youth who experience racism evidence negative developmental outcomes. In this chapter, we examine person-centered analysis (PCA)-a quantitative technique that investigates how variables combine across individuals-as a useful tool for elucidating racial and ethnic protective processes that mitigate the negative impact of racism. We review recent studies employing PCA in examinations of racial identity, racial socialization, and other race-related experiences, as well as how these constructs correlate with and impact African American youth development. We also consider challenges and limitations of PCA and conclude with a discussion of future research and how PCA might be used to promote equity and justice for African American and other racial and ethnic minority youth who experience racism.

    SuperSpec is a new spectrometer-on-a-chip technology for submm/mm-wave spectroscopy. SuperSpec stands out from other direct-detection submm spectrometer technologies in that the detectors are coupled to a series of resonant filters along a single microwave feedline instead of using dispersive optics. SuperSpec makes use of kinetic inductance detectors (KIDs) to detect radiation in this filter bank. The small profile of this design makes SuperSpec a natural choice to produce a multi-object spectrometer for tomographic mapping or galaxy redshift surveys. We have recently fabricated a device that is a 50 channel subset of a full 280 channel filter bank, which would cover the 190 - 310 GHz range at R = 275. Analysis of the data from this device informs us of the potential design modifications to enable a high-yield background-limited SuperSpec spectrometer. The results indicate that this subset filter bank can scale up to a full filter bank with only a few collisions in readout space and less than 20% variation in responsivity for the detectors. Additionally, the characterization of this and other prototype devices suggests that the noise performance is limited by generation-recombination noise. Finally, we find that the detectors are sufficiently sensitive for ground-based spectroscopy at R = 100, appropriate for tomographic mapping experiments. Further modifications are required to reach the background limit for R = 400, ideal for spectroscopy of individual galaxies.

  6. Listening to their voices: Exploring mathematics-science identity development of African American males in an urban school community

    Wilson, Kimi Leemar

    National data continues to show an underrepresentation of African American males pursuing science, technology, engineering and mathematics (STEM) majors, careers and professions in the United States. Whites and Asian Americans are continuously positioned as the face of STEM education and participation. And while research has provided ways to support mathematics and science learning for African American males, there still remains a gap in understanding how their formed mathematics-science identities in K-12 public schooling influences STEM participation. The research undertaken in this study explores this gap, and uses an integrative identity framework to understand mathematics-science identity development which goes beyond personal identity, and explores the relational, collective and material components of identity. Specifically, this research seeks to answer the following research questions: What are the shared lived experiences that exist between a group of African American male students developing a mathematics-science identity, and how these shared lived experiences shape their mathematics-science identity development? Therefore, by analyzing African American males lived experiences employing an integrative identity framework fosters a greater understanding of how mathematics-science identity is formed in K-12 public schools, which impacts STEM education and participation. The high school aged youth featured in this study consist of four African American males, who live in a moderate size city in California. Data for this study consists of observations, phenomenological interviews, and policy document analysis that took place over six months. Data has been analyzed to describe and interpret the young men's mathematics and science experiences, as revealed in their K-12 public school education. This inquiry sought to make meaning of how African American males experience mathematics and science teaching and learning within K-12 public schooling and how these

    2012-01-01

    This qualitative study explored perspectives of emerging adult African American women on the development of mature love relationships. Inductive analysis of focus group interviews, conducted with a purposive sample of 31 African American women, yielded themes related to relationship goals and characteristics, and interpersonal and societal challenges to finding the right partner and developing a mature love relationship. Core categories that emerged from analysis of the discussions were (1) age and relationship goal differences within the emerging adult group, (2) mature love relationship goals and characteristics, (3) interpersonal obstacles to finding the right partner, and (4) societal obstacles to finding the right partner. Two approaches-black womanist/feminist thought (Collins, 2000 ; Walker, 1983 ) and relationship maturity theory (Paul & White, 1990 )-were then combined to explain the influence of historic and contemporary interpersonal and societal factors on developmental and ethnic issues that challenge positive gender identity formation, hasten intimacy maturity, and hinder the development of mature love relationships among emerging adult African American women. For these women, premature responsibility, especially early caregiver burden, was related to the early development of intimacy capacity and the desire for a mature love relationship, to be protected, and to have someone to help carry the load. Interracial dating, negative stereotypic images of African American women, and even positive images of enduring black love relationships posed difficult challenges to positive identity formation and intimacy maturity. A primary challenge was to counteract negative stereotypic images, so that they could develop their own self-identities as women and as relationship partners.

The objective of our study was to assess, in a participative way, the educational needs for public health and health workforce development among potential trainees and training institutions in nine French-speaking African countries. A needs assessment was conducted in the target countries according to four approaches: (1) Review at national level of health challenges. (2) Semi-directed interviews with heads of relevant training institutions. (3) Focus group discussions with key-informants. (4) A questionnaire-based study targeting health professionals identified as potential trainees. A needs assessment showed important public health challenges in the field of health workforce development among the target countries (e.g. unequal HRH distribution in the country, ageing of HRH, lack of adequate training). It also showed a demand for education and training institutions that are able to offer a training programme in health workforce development, and identified training objectives and core competencies useful to potential employers and future trainees (e.g. leadership, planning/evaluation, management, research skill). In combining various approaches our study was able to show a general demand for health managers who are able to plan, develop and manage a nation's health workforce. It also identified specific competencies that should be developed through an education and training program in public health with a focus on health workforce development.

    Background There is a proliferation of lifestyle-oriented mobile technologies; however, few have targeted users. Through intervention mapping, investigators and community partners completed Steps 1–3 (needs assessment, formulation of change objectives, and selection of theory-based methods) of a process to develop a mobile cancer prevention application (app) for cancer prevention. The aim of this qualitative study was to complete Step 4 (intervention development) by eliciting input from African American (AA) breast cancer survivors (BCSs) to guide app development. Methods Four focus group discussions (n=60) and three individual semi-structured interviews (n=36) were conducted with AA BCSs (40–72 years of age) to assess barriers and strategies for lifestyle change. All focus groups and interviews were recorded and transcribed verbatim. Data were analyzed with NVivo qualitative data analysis software version 10, allowing categories, themes, and patterns to emerge. Results Three categories and related themes emerged from the analysis: 1) perceptions about modifiable risk factors; 2) strategies related to adherence to cancer prevention guidelines; and 3) app components to address barriers to adherence. Participant perceptions, strategies, and recommended components guided development of the app. Conclusions For development of a mobile cancer prevention app, these findings will assist investigators in targeting features that are usable, acceptable, and accessible for AA BCSs.

    A critical complication of factor VIII (FVIII) replacement therapy in Haemophilia A (HA) treatment is inhibitor development. Known genetic factors predisposing to inhibitor development include FVIII (F8) gene mutations, ethnicity, a family history of inhibitors and FVIII haplotype mismatch. The aim of this study was to characterize and correlate these genetic factors in a cohort of South African HA patients. This was a retrospective study that included 229 patients and involved the analysis of patient files, HA molecular and clinical databases and molecular analysis of the F8 gene haplotype. Of the 229 patients, 51% were of black ethnicity, 49% were white, 5% had mild HA, 4% were moderate and 91% were severe, 36% were int22 positive and 13% were inhibitor positive. Of the inhibitor positive patients, 72% were black patients. Inhibitors were reported in 27% of black int22 positive patients, 13% of black int22 negative patients, 9% of white int22 positive patients and 7% of white int22 negative. The H1 haplotype was more common in whites (75%) and H2 was more common in blacks (74%). H3 and H5 were only found in black patients and had a higher frequency of inhibitor development than H1 and H2. In this small HA cohort, black patients had a significantly higher frequency of inhibitor development and the results were indicative of an association between inhibitor development, ethnicity and haplotype.

    Background The European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life Group is currently developing computerized adaptive testing measures for the Quality of Life Questionnaire Core-30 (QLQ-C30) scales. The work presented here describes the development of an EORTC item bank for emotional functioning (EF), which is one of the core domains of the QLQ-C30. Methods According to the EORTC guidelines on module development, the development of the EF item bank comprised four phases, of which the phases I–III are reported in the present paper. Phase I involved defining the theoretical framework for the EF item bank and a literature search. Phase II included pre-defined item selection steps and a multi-stage expert review process. In phase III, feedback from cancer patients from different countries was obtained. Results On the basis of literature search in phase I, a list of 1750 items was generated. These were reviewed and further developed in phase II with a focus on relevance, redundancy, clarity, and difficulty. The development and selection steps led to a preliminary list of 41 items. In phase III, patient interviews (N = 41; Austria, Denmark, Italy, and the UK) were conducted with the preliminary item list, resulting in some minor changes to item wording. The final list comprised 38 items. Discussion The phases I–III of the developmental process have resulted in an EF item list that was well accepted by patients in several countries. The items will be subjected to larger-scale field testing in order to establish their psychometric characteristics and their fit to an item response theory model. PMID:24217943

    Objective This study’s objective was to develop a measure of social health using item response theory as part of the Patient Reported Outcomes Measurement Information System (PROMIS). Methods After candidate items were generated from review of prior literature, focus groups, expert input, and cognitive interviews, items were administered to youth aged 8–17 as part of the PROMIS pediatric large scale testing. Exploratory and confirmatory factor analyses were used to assess dimensionality and to identify instances of local dependence. Items that met the unidimensionality criteria were subsequently calibrated using Samejima’s Graded Response Model. Differential item functioning was examined by gender and age. Results The sample included 3,048 youth who completed the questionnaire (51.8% female, 60% white, and 22.7% with chronic illness). The initial conceptualization of social function and sociability did not yield unidimensional item banks. Rather, factor analysis revealed dimensions contrasting peer relationships and adult relationships. The analysis also identified dimensions formed by responses to positively versus negatively worded items. The resulting 15-item bank measures quality of peer relationships and has strong psychometric characteristics as a full bank or an 8-item short form. Conclusions The PROMIS pediatric peer relationships scale demonstrates good psychometric characteristics and addresses an important aspect of child health. PMID:23772887

    The establishment of a Tissue Bank and the science of Tissue Banking in South Africa started in the 1960s and is still developing. This article describes the development and growth of Tissue Banking in South Africa. The current emphasis is to supply viable bone products that have been produced under the best possible quality controlled circumstances; with the collaboration between different Organ Donation Organisations. Through collaboration, a dramatic increase in the number of donors was noted over the years. Concurrently, there was a dramatic increase in the usage of different allograft products and now necessitates the development of new graft materials for expanding patient options. As an ongoing concern, the Tissue Bank in South Africa experienced an ever increase in costs to enhance quality/safety controls: increase in historical patient information, documentation and serological testing in a population struggling to control HIV. To date, the South African Tissue Bank has not experienced any untoward patient incidence since the 1960s and currently is getting over 500 donors per year.

  11. Development of a Body Condition Scoring Index for Female African Elephants Validated by Ultrasound Measurements of Subcutaneous Fat

    Obesity-related health and reproductive problems may be contributing to non-sustainability of zoo African elephant (Loxodonta africana) populations. However, a major constraint in screening for obesity in elephants is lack of a practical method to accurately assess body fat. Body condition scoring (BCS) is the assessment of subcutaneous fat stores based on visual evaluation and provides an immediate appraisal of the degree of obesity of an individual. The objective of this study was to develop a visual BCS index for female African elephants and validate it using ultrasound measures of subcutaneous fat. To develop the index, standardized photographs were collected from zoo (n = 50) and free-ranging (n = 57) female African elephants for identifying key body regions and skeletal features, which were then used to visually determine body fat deposition patterns. This information was used to develop a visual BCS method consisting of a list of body regions and the physical criteria for assigning an overall score on a 5-point scale, with 1 representing the lowest and 5 representing the highest levels of body fat. Results showed that as BCS increased, ultrasound measures of subcutaneous fat thickness also increased (P<0.01), indicating the scores closely coincide with physical measures of fat reserves. The BCS index proved to be reliable and repeatable based on high intra- and inter-assessor agreement across three assessors. In comparing photographs of wild vs. captive African elephants, the median BCS in the free-ranging individuals (BCS = 3, range 1–5) was lower (P<0.001) than that of the zoo population (BCS = 4, range 2–5). In sum, we have developed the first validated BCS index for African elephants. This tool can be used to examine which factors impact body condition in zoo and free-ranging elephants, providing valuable information on how it affects health and reproductive potential of individual elephants.

    • Premise of the study: Microsatellites were developed in the vulnerable African rainforest tree Afzelia bipindensis to investigate gene flow patterns. • Methods and Results: Using 454 GS-FLX technique, 16 primer sets were identified and optimized, leading to 11 polymorphic and readable markers displaying each six to 25 alleles in a population. Up to four alleles per individual were found in each of the loci, without evidence of fixed heterozygosity, suggesting an autotetraploid genome. Cross-amplification succeeded for all loci in the African rainforest species A. pachyloba and A. bella, which appeared tetraploid, and for most loci in the African woodland species A. africana and A. quanzensis, which appeared diploid, but failed in the Asian species A. xylocarpa. Flow cytometry confirmed the suspected differences in ploidy. • Conclusions: African Afzelia species are diploid or tetraploid, a situation rarely documented in tropical trees. These newly developed microsatellites will help in the study of their mating system and gene flow patterns. PMID:25606356

    African-American women have the highest prevalence of adult obesity in the United States. They are less likely to participate in weight-loss programs and tend to have a low success rate when they do so. The goal of this project was to explore the use of the Health Belief Model in developing culturally appropriate weight-management programs for African-American women. Seven focus groups were conducted with 50 African-American women. The Health Belief Model was used as the study's theoretical framework. Participants made a clear delineation between the terms healthy weight, overweight, and obese. Sexy, flirtatious words, such as thick, stacked, and curvy were often used to describe their extra weight. Participants accurately described the health risks of obesity. Most believed that culture and genetics made them more susceptible to obesity. The perceived benefits of losing weight included reduced risk for health problems, improved physical appearance, and living life to the fullest. Perceived barriers included a lack of motivation, reliable dieting information, and social support. Motivators to lose weight included being diagnosed with a health problem, physical appearance, and saving money on clothes. Self-efficacy was primarily affected by a frustrated history of dieting. The data themes suggest areas that should be addressed when developing culturally appropriate weight-loss messages, programs, and materials for African-American women.

    There is a real need to develop new therapeutic strategies for African trypanosomiasis infections. In our study, we developed a new drug delivery system of diminazene (DMZ), a trypanocidal drug registered for veterinary use. This drug candidate presents a limited efficacy, a poor affinity for brain tissue and instability. The development of colloidal formulations based on a porous cationic nanoparticle with an oily core (70DGNP + ), has potentially two advantages: stabilization of the drug and potential targeting of the parasite. We analyzed two processes of drug loading: in process (DMZ was added during the preparation of 70DGNP + at 80 °C) and post-loading (DMZ was mixed with a 70DGNP + solution at room temperature). Poor stability of the drug was observed using the in process technique. When using the post-loading technique over 80% drug entrapment efficiency was obtained at a ratio of DMZ:phospholipids (wt:wt) < 5%. Moreover, DMZ loaded into 70DGNP + was found to be protected against oxidation and was stable for at least six months at 4 °C. Finally, in vitro tests on T.b. brucei showed an increased efficacy of DMZ loaded in 70DGNP + .

    The thermal dissipation of activated eggs and embryos undergoing development from cleavage to the tailbud stage of the African clawed frog Xenopus laevis was measured as a function of incubation time at temperatures ranging from T = 288.2 K to 295.2 K, using a high-precision isothermal calorimeter. A23187-mediated activation of mature eggs induced stable periodic thermal oscillations lasting for 8-34 h. The frequency agreed well with the cell cycle frequency of initial cleavages at the identical temperature. In the developing embryo, energy metabolism switches from embryonic to adult features during gastrulation. The thermal dissipation after gastrulation fit well with a single modified Avrami equation, which has been used for modeling crystal-growth. Both the oscillation frequency of the activated egg and the growth rate of the embryo strongly depend on temperature with the same apparent activation energy of approximately 87 kJ mole(-1). This result suggests that early development proceeds as a single biological time, attributable to a single metabolic rate. A temperature-independent growth curve was derived by scaling the thermogram to the biological time, indicating that the amount of energy expenditure during each developmental stage is constant over the optimal temperature range.

    The Arab region of the Middle East and North Africa (MENA) suffers from arid conditions, dense population, and inefficient use of fresh water resources. In addition, the lack of data sharing between nations has made accurate monitoring of the water cycle in the MENA difficult. These factors have nearly exhausted the existing fresh water resources in the region and have led to a re-evaluation of water management plans and budgeting schemes between nations. In order to utilize the existing resources more efficiently, it is necessary that all nations within the MENA have access to optimal estimates of hydrological states and fluxes relevant to water resources. This presentation will introduce a methodology and implementation strategy designed to provide frequent regional estimates of the water budget through the development of a Land Data Assimilation System designed specifically for the Middle Eastern and North African (MENA LDAS) region. The MENA LDAS optimally merges available in situ data with satellite-based estimates of meteorological variables including data from the Gravity Recovery and Climate Experiment (GRACE), the Moderate Resolution Imaging Spectroradiometer (MODIS), and the Tropical Rainfall Measuring Mission (TRMM) within a land surface modeling framework. As a result of this effort, a platform for data sharing among MENA nations is being developed to provide timely regional estimates of hydrological states and fluxes at 1/8th degree resolution. To be discussed will be the development and status of the system, and preliminary results from land surface model simulations over the region.

    Human African trypanosomiasis (HAT) is a disease caused by Kinetoplastid infection. Serological tests are useful for epidemiological surveillance. The aim of this study was to develop a multiplex serological assay for HAT to assess the diagnostic value of selected HAT antigens for sero-epidemiological surveillance. We cloned loci encoding eight antigens from Trypanosoma brucei gambiense, expressed the genes in bacterial systems, and purified the resulting proteins. Antigens were subjected to Luminex multiplex assays using sera from HAT and VL patients to assess the antigens' immunodiagnostic potential. Among T. b. gambiense antigens, the 64-kDa and 65-kDa invariant surface glycoproteins (ISGs) and flagellar calcium binding protein (FCaBP) had high sensitivity for sera from T. b. gambiense patients, yielding AUC values of 0.871, 0.737 and 0.858 respectively in receiver operating characteristics (ROC) analysis. The ISG64, ISG65, and FCaBP antigens were partially cross-reactive to sera from Trypanosoma brucei rhodesiense patients. The GM6 antigen was cross-reactive to sera from T. b. rhodesiense patients as well as to sera from VL patients. Furthermore, heterogeneous antibody responses to each individual HAT antigen were observed. Testing for multiple HAT antigens in the same panel allowed specific and sensitive detection. Our results demonstrate the utility of applying multiplex assays for development and evaluation of HAT antigens for use in sero-epidemiological surveillance.

To determine whether genetically determined African ancestry is associated with neuropathological changes commonly associated with dementia, we analyzed a population-based brain bank in the highly admixed city of São Paulo, Brazil. African ancestry was estimated through the use of previously described ancestry-informative markers. Risk of presence of neuritic plaques, neurofibrillary tangles, small vessel disease, brain infarcts and Lewy bodies in subjects with significant African ancestry versus those without was determined. Results were adjusted for multiple environmental risk factors, demographic variables and apolipoprotein E genotype. African ancestry was inversely correlated with neuritic plaques (P=0.03). Subjects with significant African ancestry (n=112, 55.4%) showed lower prevalence of neuritic plaques in the univariate analysis (odds ratio (OR) 0.72, 95% confidence interval (CI) 0.55-0.95, P=0.01) and when adjusted for age, sex, APOE genotype and environmental risk factors (OR 0.43, 95% CI 0.21-0.89, P=0.02). There were no significant differences for the presence of other neuropathological alterations. We show for the first time, using genetically determined ancestry, that African ancestry may be highly protective of Alzheimer's disease neuropathology, functioning through either genetic variants or unknown environmental factors. Epidemiological studies correlating African-American race/ethnicity with increased Alzheimer's disease rates should not be interpreted as surrogates of genetic ancestry or considered to represent African-derived populations from the developing nations such as Brazil.

    Social inequalities in the United States resulted in negative health outcomes for the African Americans. Their stressful living conditions of poverty, discrimination, racism, abuse and rejection from American society contribute to their negative health outcomes. The lifestyles of African Americans have been influenced by poverty and prior injustices, which have molded their worldview of health and illness. Dr. Martin Luther King, national civil rights leader, brought about social change with much prayer; however, he went a step further with collective gatherings to include the power of non-violence massive public demonstrations. This paper is an analytical review of the literature addressing social inequalities impacting on health inequalities of African Americans resulting in health disparities. Policy changes are propose by implementing transformation development and community empowerment models as frameworks for community/public health nurses in guiding African American communities with addressing health disparities. These models empower members of the community to participate in a collaborative effort in making political and social changes to improve their overall health outcomes.

    The Millennium Development Goals’ target to halve the proportion of people who suffer from hunger is extremely important in southern Africa, where food security has become increasingly problematic over the last 20 years. One “quick-win” proposal is replenishment of soil nutrients for smallholder farmers, through free or subsidised chemical fertilisers. Other proposals include appropriate irrigation technology, improved inputs and interventions targeted at women. Analysis of over 10 years of agro-hydrological and agro-economic studies from southern African show that a different approach is required to interventions proposed. There are sustainability problems with free chemical fertiliser due to transport costs and ancillary costs. Furthermore, recent studies in Zimbabwe and Mozambique show that significant increases in yield can only be obtained when soil fertility management is combined with good crop husbandry, e.g. timely planting and weeding. Ongoing replenishment of fertility would be dependent on a continued free or subsidised fertiliser supply, and transport system. Increasing access to irrigation will help, but is not the only solution and cannot reach even a majority of farmers. It has been determined that short dryspells are often the major cause of low yields in sub-Saharan Africa. Soil-water conservation approaches, e.g. winter weeding and conservation tillage, can reduce risk and increase yield. The following specific recommendations are made for urgent interventions to contribute sustainably to food security in southern Africa: (i) To increases access to fertiliser, consider development of strong input markets at end-user level. (ii) Intensification of technology transfer, focusing on capacity building for transfer of existing technologies and much closer collaboration between state and NGO sectors, agronomists and water engineers. (iii) Increasing the uptake of soil-water conservation methods, including conservation tillage and weeding, and

    The rate of HIV infection among African Americans is disproportionately higher than for other racial groups in the United States. Previous research suggests that low level of health literacy (HL) is an underlying factor to explain racial disparities in the prevalence and incidence of HIV/AIDS. The present research describes a community and university project to develop a culturally tailored HIV/AIDS HL toolkit in the African American community. Paulo Freire's pedagogical philosophy and problem-posing methodology served as the guiding framework throughout the development process. Developing the HIV/AIDS HL toolkit occurred in a two-stage process. In Stage 1, a nonprofit organization and research team established a collaborative partnership to develop a culturally tailored HIV/AIDS HL toolkit. In Stage 2, African American community members participated in focus groups conducted as Freirian cultural circles to further refine the HIV/AIDS HL toolkit. In both stages, problem posing engaged participants' knowledge, experiences, and concerns to evaluate a working draft toolkit. The discussion and implications highlight how Freire's pedagogical philosophy and methodology enhances the development of culturally tailored health information.

    Objective To examine dental caries development and caries risk factors among preschool African-American children from low-income families in Detroit, Michigan over a four- year window. Methods Data came from a representative sample of 1,021 children (zero to five years) and their caregivers in Detroit. The baseline participants in 2002–03 (W1) were reexamined in 2004–05 (W2) and 2007 (W3). Caries was measured using the International Caries Detection and Assessment System. Bivariate and multivariate analyses for repeated data were conducted to explore associations between caries increment outcomes and demographics, access to dental care, oral health-related behaviors, and social and physical environments. Results The mean number of new NCCL (non-cavitated caries lesions) was 2.8 between W1 and W2 and 2.6 between W2 and W3, while the mean number of new CCL (cavitated caries lesions) was 2.0 and 2.0, respectively, during the same time periods. In younger children (< three years old in W1) higher number of new NCCL than new CCL were observed in both W1–W2 and W2–W3. The risk of new NCCL was associated with child’s soda intake and caregiver’s age. For the risk of new CCL, significant risk factors included baseline NCCL, baseline CCL, as well as child’s age. Baseline caries and child’s soda intake were also associated with the risk of developing new decayed, missing, and filled tooth surfaces. Conclusions Higher number of new NCCL relative to CCL was developed among low-income Africa-American children during early childhood. New caries development was associated with baseline caries and child’s soda intake. PMID:25441657

    This interpretivist study focused on the professional development of three African American science teachers from a small rural school district, Carver School District (pseudonym), in the southeastern United States. Stories teachers shared of their experiences in teaching and learning science and in their professional development were analyzed using a feminist poststructural analysis of power, knowledge/meaning, language, and difference. For science teaching, power was viewed as a form of ownership or possession and also as effect and processes that impact teaching, learning, and professional development. Teachers through instructional practices exerted a certain amount of power in their classrooms. Teaching practices heavily influenced student learning in science classrooms. For teacher professional development, power was viewed as effecting relationships between administration, peers, and students as a shifting force within different social contexts. Science teachers were perceived as objects of the system and as active social agents who in particular relations of power acted in their best interests as they developed as science teachers. Teachers negotiated for themselves certain power relations to do as they wished for teaching science and for participating in teacher professional development activities. Power was an inherent and critically important aspect in understanding what science teachers do in their classrooms, in teaching and learning science, and in developing as science teachers. Knowledge was closely tied to relations of power in that teachers acquired knowledge about themselves, their teaching of science, and their students from their past experiences and professional development activities. Through language, interactions between teachers and students enabled or disabled access to the culture of power via instructional practices. Language was implicated in teacher professional development as a powerful force for advancing or hindering teachers

    Human African trypanosomiasis (HAT, better called as sleeping sickness), caused by two morphologically identicalprotozoan parasite Trypanosoma bruceiis transmitted by the bite of tsetse flies of Glossinagenus, mainly in the rural areas of the sub-Saharan Africa. HAT is one of the neglected tropical diseases and is characterized by sleep disturbance as the main symptom, hence is called as sleeping sickness. As it is epidemic in the poorest population of Africa, there is limited availability of safe and cost-effective tools for controlling the disease. Trypanosoma bruceigambiense causes sleeping sickness in Western and Central Africa, whereas Trypanosoma bruceirhodesiense is the reason for prevalence of sleeping sickness in Eastern and Southern Africa. For the treatment of sleeping sickness, only five drugs have been approved suramin, pentamidine, melarsoprol, eflornithine and nifurtimox. Various small molecules of diverse chemical nature have been synthesized for targeting HAT and many of them are in the clinical trialsincluding fexinidazole (phase I completed) and SCYX-7158 (advanced in phase I). The present work has been planned to review various types of small molecules developed in the last 10 years having potent antitrypanosoma activity likely to be beneficial in sleeping sickness along with different natural anti-HAT agents.

    Transboundary aquifer (TBA) management, in part, seeks to mitigate degradation of groundwater resources caused either by an imbalance of abstraction between countries or by cross-border pollution. Fourteen potential TBAs were identified within a hydrogeological mapping programme based on simple hydrogeological selection criteria for the Southern African Development Community (SADC) region. These have been reassessed against a set of data associated with five categories: (1) groundwater flow and vulnerability (which is perceived as the over-arching influence on the activity level of each TBA), (2) knowledge and understanding, (3) governance capability, (4) socio-economic/water-demand factors, and (5) environmental issues. These assessments enable the TBAs to be classified according to their need for cross-border co-operation and management. The study shows that only two of the 14 TBAs have potential to be the cause of tension between neighbouring states, while nine are potentially troublesome and three are unlikely to become problematic even in the future. The classification highlights the need to focus on data gathering to enable improved understanding of the TBAs that could potentially become troublesome in the future due to, for example, change in demographics and climate.

    The Bahama Archipelago consists of an arcuate chain of carbonate platforms. Average water depths on the platform-tops, such as the Great Bahama Bank (GBB), are typically 10 m or less, with coral reef-rimmed margins, thick sediment accumulations, and the frequent occurrence of islands. There are, however, exceptions. For example, Cay Sal Bank (CSB), a little studied detached Bahamian carbonate platform with depths ranging from 30 to 7 m, is only slightly deeper than the GBB, but devoid of islands, lacks platform-margin coral reefs and holds little sediment on the platform-top; the platform is incipiently drowned. CSB is interesting as it is conspicuously larger (6000 sq. km) than other incipiently drowned platforms in the region, such as Serranilla Bank (1100 sq. km) and the Cat Island platform (1500 sq. km). Field and remote sensing data are assembled to provide insight into the sedimentology and geomorphology of the CSB. The influence of ocean climate, regional hydrodynamics, and Holocene flooding history are investigated to understand why platform-margin coral reef growth on CSB has been unable to keep pace with Holocene sea-level rise. A decade of regional sea-surface temperature data for the Bahamas report CSB to be situated in the same ocean climate regime as GBB. Temperature cannot explain the platform's different morphologies. The Florida Current has been evoked as a possible reason for the immature development of platform-top processes on the CSB, but numeric modeling suggests its influence to be restricted to the deep flanks of the bank. Further, sediment distribution on CSB, including infill patterns of karst depressions, suggest trade winds (easterlies) to drive platform-top hydrodynamics. By assembling a satellite-derived bathymetry map, it can be shown that CSB flooded earlier and at relatively higher rates of Holocene sea-level rise than its neighboring platforms. Flooding history is identified as the most feasible explanation for the atypical

    This study describes the development of a spiritually based intervention to increase colorectal cancer screening through African American churches by framing the health message with spiritual themes and scripture. The intervention development phase consisted of ideas from an advisory panel and core content identified in focus groups. In the pilot-testing phase, prototypes of the intervention materials were tested for graphic appeal in additional focus groups, and content was tested for acceptability and comprehension in cognitive interviews. Participants preferred materials showing a variety of African Americans in real settings, bright color schemes, and an uplifting message emphasizing prevention and early detection. Spiritual themes such as stewardship over the body, being well to serve God, and using faith to overcome fear, were well received. The materials were then finalized for implementation and will be used by community health advisors to encourage screening.

    Open cast mining has a strong impact on the environment, the intensity depending on the morphology of the deposit and on the nature of the minerals. At Touro mine (NW Spain) there is a large area covered by tailings, one of which, called the "sedimentation bank", was used to deposit sludge resulting from the extraction of copper in the flotation plant. Three zones were selected and the soils were sampled to analyse the changes brought about by vegetation on the chemical and mineralogical properties of the soils developed over the sedimentation bank and its development over time. The vegetation increased the pH, contents of organic material, nitrogen, clay and free oxides of Fe and Al, and the cationic exchange capacity of the soils. The decrease in the sulphide content, benefited by the vegetation process, led to a reduction in the total content of Cr and Cu. The vegetation also contributed towards the alteration of the primary minerals. The transformation of jarosite, the formation of nanocrystals of hematite, goethite, hydroxypolymers, and amorphous minerals that contained Cu, Cr and Pb were observed. Nevertheless the high Cu and Cr contents indicate that it is advisable to change the restoration process.

    Objective: To use a patient-centered approach or participatory action research design combined with advanced psychometrics to develop a comprehensive patient-reported outcomes (PRO) measurement system specifically for individuals with traumatic brain injury (TBI). This TBI Quality-of-Life (TBI-QOL) measurement system expands the work of other large PRO measurement initiatives, that is, the Patient-Reported Outcomes Measurement Information System and the Neurology Quality-of-Life measurement initiative. Setting: Five TBI Model Systems centers across the United States. Participants: Adults with TBI. Design: Classical and modern test development methodologies were used. Qualitative input was obtained from individuals with TBI, TBI clinicians, and caregivers of individuals with TBI through multiple methods, including focus groups, individual interviews, patient consultation, and cognitive debriefing interviews. Item pools were field tested in a large multisite sample (n = 675) and calibrated using item response theory methods. Main Outcomes Measures: Twenty-two TBI-QOL item banks/scales. Results: The TBI-QOL consists of 20 independent calibrated item banks and 2 uncalibrated scales that measure physical, emotional, cognitive, and social aspects of health-related quality of life. Conclusions: The TBI-QOL measurement system has potential as a common data element in TBI research and to enhance collection of health-related quality-of-life and PRO data in rehabilitation research and clinical settings.

  17. Enhanced Bank of Kalman Filters Developed and Demonstrated for In-Flight Aircraft Engine Sensor Fault Diagnostics

    Kobayashi, Takahisa; Simon, Donald L.

    2005-01-01

    In-flight sensor fault detection and isolation (FDI) is critical to maintaining reliable engine operation during flight. The aircraft engine control system, which computes control commands on the basis of sensor measurements, operates the propulsion systems at the demanded conditions. Any undetected sensor faults, therefore, may cause the control system to drive the engine into an undesirable operating condition. It is critical to detect and isolate failed sensors as soon as possible so that such scenarios can be avoided. A challenging issue in developing reliable sensor FDI systems is to make them robust to changes in engine operating characteristics due to degradation with usage and other faults that can occur during flight. A sensor FDI system that cannot appropriately account for such scenarios may result in false alarms, missed detections, or misclassifications when such faults do occur. To address this issue, an enhanced bank of Kalman filters was developed, and its performance and robustness were demonstrated in a simulation environment. The bank of filters is composed of m + 1 Kalman filters, where m is the number of sensors being used by the control system and, thus, in need of monitoring. Each Kalman filter is designed on the basis of a unique fault hypothesis so that it will be able to maintain its performance if a particular fault scenario, hypothesized by that particular filter, takes place.

    Globally, tobacco kills more people than HIV-related conditions or AIDS, tuberculosis and malaria combined. In 1991, The World Bank, the world's largest lender, pledged that it would no longer support tobacco-related projects. It was expected that other financial investors would follow, but most did not respond to this call. As a result, several financial institutions continue to invest in tobacco and fuel an epidemic to an unprecedented scale. Using tobacco as a case in point, this review highlights the continuing investments among financial institutions which do not conform to 'socially responsible investments' and calls for monitoring and reporting such unethical practices. The paper also underscores the need to harmonise the numerous criteria, principles and voluntary codes that govern socially responsible investing and ensure that financial institutions comply with them.

    Damian, Rodica Ioana; Simonton, Dean Keith

    2015-04-01

    Symptoms associated with mental illness have been hypothesized to relate to creative achievement because they act as diversifying experiences. However, this theory has only been tested on predominantly majority-culture samples. Do tendencies toward mental illness still predict eminent creativity when they coexist with other diversifying experiences, such as early parental death, minority-status, or poverty? These alternative diversifying experiences can be collectively referred to as examples of developmental adversity. This conjecture was tested on a significant sample of 291 eminent African Americans who, by the nature of their status as long-term minorities, would experience more developmental adversity. Replicating majority-culture patterns, African American artists showed higher mental illness rates than African American scientists. Yet the absolute percentages were significantly lower for the African Americans, regardless of profession. Furthermore, mental illness predicted higher eminence levels only for the African American artists, an effect that diminished when controlling for developmental adversity. Because the latter predicted eminence for both artists and scientists, the "madness-to-genius" link probably represents just 1 of several routes by which diversifying experiences can influence eminence. The same developmental ends can be attained by different means. This inference warrants further research using other eminent creators emerging from minority culture populations.

    2008-10-01

    This work studied the sequential morphological changes of omasum in foetuses, neonates and adult West African Dwarf (WAD) goats by gross and light microscopic methods. The mean omasal volume was 1.37 +/- 0.36, 4.2 +/- 0.4, 8.7 +/- 6.9 and 60.1 +/- 8.6 ml for gestation day 87 and 146 foetuses, neonates and adults respectively. Grossly the mucosa exhibited longitudinally oriented primary, secondary, tertiary and quartnery laminae with smooth surface in foetuses and numerous papillae in the adults. Microscopically it was lined by stratified squamous epithelium which was divided into larger lighter luminal and smaller darker basal zones in gestation day 60 foetuses. The core of the laminae contained extension of the inner muscular tunic. The basal zone developed lateral evaginations (corial papillae) into the lighter zone of the laminae in gestation day 106 foetuses. By term these corial papillae approached the luminal surface. The papillae emerged above the luminal surface in 4 week old neonates. The papillae were fully developed in adult goats. The mean papillary height and width were -205.1 +/- 34.0, 67.0 +/- 9.6; 235.0 +/- 86.5, 185.0 +/- 42.3 and 570.3 +/- 60.0, 290.1 +/- 66.3 microm for foetuses, neonates and adult goats. The inner circular layer was thicker than the outer longitudinal layer of the muscular tunic. The central muscular layer of the laminae originated from the inner circular layer with attachment to the outer muscular layer in adults. This attachment could be adaptation for better anchorage and muscular contraction of the laminae in WAD goats.

    Shortages, geographic imbalances and poor performance of health workers pose major challenges for improving health service delivery in developing countries. In response, multilateral agencies have increasingly recognized the need to invest in human resources for health (HRH) to assist countries in achieving their health system goals. In this paper we analyse the HRH-related activities of three agencies: the Global Alliance for Vaccines and Immunisation (GAVI); the Global Fund for Aids, Tuberculosis, and Malaria (the Global Fund); and the World Bank. First, we reviewed the type of HRH-related activities that are eligible for financing within each agency. Second, we reviewed the HRH-related activities that each agency is actually financing. Third, we reviewed the literature to understand the impact that GAVI, Global Fund and World Bank investments in HRH have had on the health workforce in developing countries. Our analysis found that by far the most common activity supported across all agencies is short-term, in-service training. There is relatively little investment in expanding pre-service training capacity, despite large health worker shortages in developing countries. We also found that the majority of GAVI and the Global Fund grants finance health worker remuneration, largely through supplemental allowances, with little information available on how payment rates are determined, how the potential negative consequences are mitigated, and how payments are to be sustained at the end of the grant period. Based on the analysis, we argue there is an opportunity for improved co-ordination between the three agencies at the country level in supporting HRH-related activities. Existing initiatives, such as the International Health Partnership and the Health Systems Funding Platform, could present viable and timely vehicles for the three agencies to implement this improved co-ordination.

  13. African Scientific Network: A model to enhance scientific research in developing countries

    2002-03-01

    Africa has over 350 higher education institutions with a variety of experiences and priorities. The primary objectives of these institutions are to produce white-collar workers, teachers, and the work force for mining, textiles, and agricultural industries. The state of higher education and scientific research in Africa have been discussed in several conferences. The proposals that are generated by these conferences advocate structural changes in higher education, North-South institutional linkages, mobilization of the African Diaspora and funding. We propose a model African Scientific Network that would facilitate and enhance international scientific partnerships between African scientists and their counterparts elsewhere. A recent article by James Lamout (Financial Times, August 2, 2001) indicates that emigration from South Africa alone costs $8.9 billion in lost human resources. The article also stated that every year 23,000 graduates leave Africa for opportunities overseas, mainly in Europe, leaving only 20,000 scientists and engineers serving over 600 million people. The International Organization for Migration states that the brain drain of highly skilled professionals from Africa is making economic growth and poverty alleviation impossible across the continent. In our model we will focus on a possible networking mechanism where the African Diaspora will play a major role in addressing the financial and human resources needs of higher education in Africa

    The existing literatures highlights that the security is the primary factor which determines the adoption of Internet banking technology. The secondary information on Internet banking development in Malaysia shows a very slow growth rate. Hence, this study aims to study the banking customers perception towards security concern and Internet banking adoption through the information collected from 150 sample respondents. The data analysis reveals that the customers have much concern about security and privacy issue in adoption of Internet banking, whether the customers are adopted Internet banking or not. Hence, it infers that to popularize Internet banking system there is a need for improvement in security and privacy issue among the banking customers.

    2016-01-01

    Background Control and elimination of human African trypanosomiasis (HAT) can be accelerated through the use of diagnostic tests that are more accurate and easier to deploy. The goal of this work was to evaluate the immuno-reactivity of antigens and identify candidates to be considered for development of a simple serological test for the detection of Trypanosoma brucei gambiense or T. b. rhodesiense infections, ideally both. Methodology/Principal Findings The reactivity of 35 antigens was independently evaluated by slot blot and ELISA against sera from both T. b. gambiense and T. b. rhodesiense infected patients and controls. The antigens that were most reactive by both tests to T. b. gambiense sera were the membrane proteins VSG LiTat 1.3, VSG LiTat 1.5 and ISG64. Reactivity to T. b. rhodesiense sera was highest with VSG LiTat 1.3, VSG LiTat 1.5 and SRA, although much lower than with T. b. gambiense samples. The reactivity of all possible combinations of antigens was also calculated. When the slot blot results of 2 antigens were paired, a VSG LiTat 1.3- ISG75 combination performed best on T. b. gambiense sera, while a VSG LiTat 1.3-VSG LiTat 1.5 combination was the most reactive using ELISA. A combination of SRA and either VSG LiTat 1.3 or VSG LiTat 1.5 had the highest reactivity on T. b. rhodesiense sera according to slot blot, while in ELISA, pairing SRA with either GM6 or VSG LiTat 1.3 yielded the best results. Conclusions This study identified antigens that were highly reactive to T. b. gambiense sera, which could be considered for developing a serological test for gambiense HAT, either individually or in combination. Antigens with potential for inclusion in a test for T. b. rhodesiense HAT were also identified, but because their reactivity was comparatively lower, a search for additional antigens would be required before developing a test for this form of the disease.

  8. The development of the Garden Banks block 388 FPF mooring system

    Dove, P.G.S.; Librino, F.; Scovell, D.C.

    1995-12-01

    This paper discusses work conducted during the design, procurement and installation of Enserch Exploration, Inc.`s Garden Banks 388 FPF mooring system. The design began with the execution of a trade-off study evaluating and comparing previously installed floating production moorings in the Gulf of Mexico, coupled with evaluation of new concepts and emphasis on cost effective solutions. The design effort involved dynamic analysis and wind tunnel and model tank testing, all in accordance with the newly completed API document RP 2FP1. Inspection of various components from the Placid GC-29 FPS moorings (installed in 1987 and recovered in 1990) determined that sections of chain, jacketed spiral strand wire rope, submersible buoys and connectors could be reused with suitable refurbishment. The excellent condition of the rig`s onboard winching system also resulted in the reuse of the windlasses, with specified upgrades. Because a sufficient amount of used wire was not available, a bare spiral strand wire rope construction was adopted, including zinc anodes in the new sections, rather than jacketed strand. The lack of cost effective installation vessels in the Gulf of Mexico at the time of the installation bid posed challenges to Enserch. However, an innovative preset mooring installation scheme involving Heeremac`s SSCV Balder on its own moorings was adopted. Since the vessel was already in the Gulf of Mexico on contract for other projects, a cost effective contract was negotiated. The results of this effort led to considerable cost savings for Enserch, compared to conventional FPF mooring systems previously installed in the Gulf of Mexico.

    The Development Bank of the Philippines (DBP), the first Philippine bank to be ISO 140001 certified, plays a vital role in promoting environmental protection, health, and safety. It continues to play a proactive role in integrating environmental investments into development projects. In order to show its commitment to environmental protection and sustainable development, DBP integrates and implements environmental considerations into all aspects of its operations and services, assets management, and business decisions. It has instituted various credit programs that support the adoption of environmental technologies and continues to provide credit support to environment-friendly industrial operations; this is one of its major thrusts. The environmental credit programs are geared toward the promotion of the protection and enhancement of the quality of the environment. The objective of this research study was to determine the developmental impact of the DBP financed environmental projects in attaining sustainable development. It specifically identifies the number and amount of loan exposures on the different projects financed and the environmental benefits for the period January 2005 to December 2006.

    Research to understand how parents influence their children's dietary intake and eating behaviors has expanded in the past decades and a growing number of instruments are available to assess food parenting practices. Unfortunately, there is no consensus on how constructs should be defined or operationalized, making comparison of results across studies difficult. The aim of this study was to develop a food parenting practice item bank with items from published scales and supplement with parenting practices that parents report using. Items from published scales were identified from two published systematic reviews along with an additional systematic review conducted for this study. Parents (n = 135) with children 5-12 years old from the US and Canada, stratified to represent the demographic distribution of each country, were recruited to participate in an online semi-qualitative survey on food parenting. Published items and parent responses were coded using the same framework to reduce the number of items into representative concepts using a binning and winnowing process. The literature contributed 1392 items and parents contributed 1985 items, which were reduced to 262 different food parenting concepts (26% exclusive from literature, 12% exclusive from parents, and 62% represented in both). Food parenting practices related to 'Structure of Food Environment' and 'Behavioral and Educational' were emphasized more by parent responses, while practices related to 'Consistency of Feeding Environment' and 'Emotional Regulation' were more represented among published items. The resulting food parenting item bank should next be calibrated with item response modeling for scientists to use in the future.

    This paper describes the use of a unique "Learning and Feedbackˮ approach to customize cancer clinical trials education programs for Community Bridges, a peer training intervention designed for African-American communities in North Carolina. Generic community education modules were demonstrated with key community leaders who were designated as trainers. Quantitative and qualitative assessments were provided on understanding of content, comfort with material, and cultural relevance. The generic materials were adapted into three revised modules, all featuring key messages about cancer clinical trials, discussion regarding distrust of medical research, common misconceptions about trials, patient protections, and a call to action to prompt increased inquiry about locally available trials. The revised modules were then used as part of a train-the-trainer program with 12 African-American community leaders. ENACCT's use of the Learning and Feedback process is an innovative method for culturally adapting clinical trials education.

    OBJECTIVE: Despite generalized intervention programs, restraint use among African Americans remains below national levels, especially among children. This study describes the development and implementation of a community participatory faith-based youth injury prevention program. METHODS: Through a partnership with the African-American faith-based community and our injury prevention group, a unique multigenerational intervention program was developed targeting motor vehicle restraint use. Once developed, the program was initially evaluated by comparing outcomes between control and intervention churches. The main objective was to observe adult and pediatric restraint use before and after program implementation. RESULTS: Overall, there was excellent recognition and participation in the program. Following program implementation, significant improvements were observed in restraint use compared to control churches. In particular, there was a 72% reduction in unrestrained children, a 25% increase in children being secured in the rear-seat position and a nearly 20% increase in driver restraint use. CONCLUSIONS: The development and implementation of a culturally sensitive intervention program can significantly improve restraint use in a minority population. Partnering with the community in all phases of the program is essential to its success. PMID:16916133

    2009-01-01

    Background The objective of this study was to compare cases of imported malaria originating from the Spanish ex-colony of Equatorial Guinea (EG) with those originating from the rest of Africa (RA). Methods All the African cases detected in Barcelona between 1989 and 2007 were investigated in a retrospective analysis. Clinical-epidemiological variables such as sex, age, visiting friends and relatives (VFR), species, hospital admission and chemo-prophylaxis were compared. Data were analysed by logistic regression, calculating the Odds Ratio (OR) and 95% Confidence Intervals (95% CI). Results Of the 489 African patients, 279 (57,1%) had been born in EG and 210 (42,9%) in the rest of Africa. The cumulative incidence of imported malaria among those from EG was 179.6 per thousand inhabitants, while in those from the RA it was 33.7 per thousand (p < 0.001). Compliance with chemoprophylaxis (CP) was very low, but there were no differences between the two groups. Comparing those from EG to those from RA, the former were characterized by having more patients in the visiting friends and relatives (VFR) category, and more individuals younger than 15 years or older than 37 years, and more women. They also visited a traveller's health centre more often, had fewer hospital admissions and were less likely to reside in the inner city. Conclusion Cases of imported malaria originating in Africa, are more likely to come from the Spanish ex-colony of EG, and VFR are more likely to be affected. It is recommended that developed countries promote prevention programmes, such as CP advice directed at African immigrants, and develop programmes of cooperation against malaria in their ex-colonies.

    Over time, data warehouse (DW) systems have become more difficult to develop because of the growing heterogeneity of data sources. Despite advances in research and technology, DW projects are still too slow for pragmatic results to be generated. Here, we address the following question: how can the complexity of DW development for integration of heterogeneous transactional information systems be reduced? To answer this, we proposed methodological guidelines based on cycles of conceptual modeling and data analysis, to drive construction of a modular DW system. These guidelines were applied to the blood donation domain, successfully reducing the complexity of DW development.

    Objective To develop a calibrated item bank and computer adaptive test (CAT) to assess the effects of stigma on health-related quality of life in individuals with spinal cord injury (SCI). Design Grounded-theory based qualitative item development methods, large-scale item calibration field testing, confirmatory factor analysis, and item response theory (IRT)-based psychometric analyses. Setting Five SCI Model System centers and one Department of Veterans Affairs medical center in the United States. Participants Adults with traumatic SCI. Main Outcome Measures SCI-QOL Stigma Item Bank Results A sample of 611 individuals with traumatic SCI completed 30 items assessing SCI-related stigma. After 7 items were iteratively removed, factor analyses confirmed a unidimensional pool of items. Graded Response Model IRT analyses were used to estimate slopes and thresholds for the final 23 items. Conclusions The SCI-QOL Stigma item bank is unique not only in the assessment of SCI-related stigma but also in the inclusion of individuals with SCI in all phases of its development. Use of confirmatory factor analytic and IRT methods provide flexibility and precision of measurement. The item bank may be administered as a CAT or as a 10-item fixed-length short form and can be used for research and clinical applications. PMID:26010973

    Background: The quest for ideal bone graft substitutes still haunts orthopedic researchers. The impetus for this search of newer bone substitutes is provided by mismatch between the demand and supply of autogenous bone grafts. Bone banking facilities such as deep frozen and freeze-dried allografts are not so widely available in most of the developing countries. To overcome the problem, we have used partially decalcified, ethanol preserved, and domestic refrigerator stored allografts which are economical and needs simple technology for procurement, preparation, and preservation. The aim of the study was to assess the radiological and functional outcome of the partially decalcified allograft (by weak hydrochloric acid) in patients of benign lytic lesions of bone. Through this study, we have also tried to evolve, establish, and disseminate the concept of the bone bank. Materials and Methods: 42 cases of lytic lesions of bone who were treated by decalcified (by weak hydrochloric acid), ethanol preserved, allografts were included in this prospective study. The allograft was obtained from freshly amputated limbs or excised femoral heads during hip arthroplasties under strict aseptic conditions. The causes of lytic lesions were unicameral bone cyst (n = 3), aneurysmal bone cyst (n = 3), giant cell tumor (n = 9), fibrous dysplasia (n = 12), chondromyxoid fibroma, chondroma, nonossifying fibroma (n = 1 each), tubercular osteomyelitis (n = 7), and chronic pyogenic osteomyelitis (n = 5). The cavity of the lesion was thoroughly curetted and compactly filled with matchstick sized allografts. Results: Quantitative assessment based on the criteria of Sethi et al. (1993) was done. There was complete assimilation in 27 cases, partial healing in 12 cases, and failure in 3 cases. Functional assessment was also done according to which there were 29 excellent results, 6 good, and 7 cases of failure (infection, recurrence, and nonunion of pathological fracture). We observed that after

    Peer support interventions extend care and health information to underserved populations yet rarely address serious illness. Investigators from a well-defined academic-community partnership developed and evaluated a peer support intervention for African Americans facing advanced cancer. Evaluation methods used the Reach, Efficacy, Adoption, Implementation, Maintenance (RE-AIM) framework. Investigators initially recruited and trained 24 lay health advisors who shared information or support with 210 individuals. However, lay advisors reported barriers of medical privacy and lack of confidence working alone with people with cancer. Training was modified to match the support team model for peer support; training reached 193 volunteers, 104 of whom formed support teams for 47 persons with serious illness. Support teams were adopted by 23 community organizations, including 11 African American churches. Volunteers in teams felt prepared to implement many aspects of supportive care such as practical support (32%) or help with cancer or palliative care resources (43%). People with serious illness requested help with practical, emotional, spiritual, and quality of life needs; however, they rarely wanted advocacy (3%) or cancer or palliative care resources (5%) from support teams. Volunteers had difficulty limiting outreach to people with advanced cancer due to medical privacy concerns and awareness that others could benefit. Support teams are a promising model of peer support for African Americans facing advanced cancer and serious illness, with reach, adoption, and implementation superior to the lay advisor model. This formative initial evaluation provides evidence for feasibility and acceptance. Further research should examine the efficacy and potential for maintenance of this intervention.

    Premise of the study: Anthonotha macrophylla (Fabaceae) is a common tree species throughout the Guineo-Congolian forest that is sometimes confounded with other congeneric species; it is expected to be an interesting phylogeographical model to infer the history of the African dense forests. We developed 18 microsatellite markers from this species and tested their transferability in 15 congeneric species. Methods and Results: A genomic library was obtained using the Illumina platform, and 18 polymorphic microsatellite loci were developed. The polymorphic microsatellites displayed two to 24 alleles (average: 11.9 alleles per locus, expected heterozygosity range: 0.18–0.91, mean: 0.64) in three populations of A. macrophylla from Benin, Liberia, and Cameroon. Cross-amplification in one to nine individuals of 15 congeneric Anthonotha species (A. acuminata, A. brieyi, A. cladantha, A. crassifolia, A. ferruginea, A. fragrans, A. gilletii, A. lamprophylla, A. mouandzae, A. noldeae, A. pellegrinii, A. pynaertii, A. stipulacea, A. wijmacampensis, and A. xanderi) showed successful amplification in six to 17 loci, making most of these markers useful at the generic level. Conclusions: This set of markers will be useful to study species delimitation and the genetic structure of Anthonotha species, and thus to better understand the history of tropical African rainforests.

    Introduction: South African men are less likely to get tested for HIV than women and are more likely to commence antiretroviral treatment (ART) at later stages of disease, default on treatment, and to die from AIDS compared with women. The purpose of this study was to conduct formative research into the ideational and behavioral factors that enable or create obstacles to mens' uptake of HIV counseling and testing (HCT) and ART. The study consulted men with a goal of developing a communication campaign aimed at improving the uptake of HIV testing and ART initiation among men. Methods: Eleven focus groups and 9 in-depth interviews were conducted with 97 male participants in 6 priority districts in 4 South African provinces in rural, peri-urban, and urban localities. Results: Fears of compromised masculine pride and reputation, potential community rejection, and fear of loss of emotional control (“the stress of knowing”) dominated men's rationales for avoiding HIV testing and treatment initiation. Conclusions: A communication campaign was developed based on the findings. Creative treatments aimed at redefining a ‘strong’ man as someone who faces his fears and knows his HIV status. The resultant campaign concept was: “positive or negative—you are still the same person.” PMID:27930614

    Contagious bovine pleuropneumonia (CBPP) caused by Mycoplasma mycoides subsp. mycoides (Mmm) is an economically very important cattle disease in sub-Saharan Africa. CBPP impacts animal health and poverty of livestock-dependent people through decreased animal productivity, reduced food supply, and the cost of control measures. CBPP is a barrier to trade in many African countries and this reduces the value of livestock and the income of many value chain stakeholders. The presence of CBPP also poses a constant threat to CBPP-free countries and creates costs in terms of the measures necessary to ensure the exclusion of disease. This opinion focuses on the biomedical research needed to foster the development of better control measures for CBPP. We suggest that different vaccine development approaches are followed in parallel. Basic immunology studies and systematic OMICs studies will be necessary in order to identify the protective arms of immunity and to shed more light on the pathogenicity mechanisms in CBPP. Moreover a robust challenge model and a close collaboration with African research units will be crucial to foster and implement a new vaccine for the progressive control of this cattle plague.

    Objective To describe the development and psychometric properties of the Spinal Cord Injury-Quality of Life (SCI-QOL) Self-esteem item bank. Design Using a mixed-methods design, we developed and tested a self-esteem item bank through the use of focus groups with individuals with SCI and clinicians with expertise in SCI, cognitive interviews, and item-response theory- (IRT) based analytic approaches, including tests of model fit, differential item functioning (DIF) and precision. Setting We tested a pool of 30 items at several medical institutions across the United States, including the University of Michigan, Kessler Foundation, the Rehabilitation Institute of Chicago, the University of Washington, Craig Hospital, and the James J. Peters/Bronx Department of Veterans Affairs hospital. Participants A total of 717 individuals with SCI completed the self-esteem items. Results A unidimensional model was observed (CFI = 0.946; RMSEA = 0.087) and measurement precision was good (theta range between −2.7 and 0.7). Eleven items were flagged for DIF; however, effect sizes were negligible with little practical impact on score estimates. The final calibrated item bank resulted in 23 retained items. Conclusion This study indicates that the SCI-QOL Self-esteem item bank represents a psychometrically robust measurement tool. Short form items are also suggested and computer adaptive tests are available. PMID:26010972

  1. The Study of Development Strategy for Bank Distribution Network through the Analysis of Inter-regional Financial Transaction Network

    Hong, Jae Weon; Hong, Won Eui; Kwak, Yoon Sik

    This study attempts to shed light on the factors that influence the locations of bank branches in establishing a bank's distribution network from the angle of the network analysis. Whereas the previous studies analyzed the locations of bank branches on the basis of their geographical characteristics and image, the significance of this study rests upon the fact that it endeavors to explore the location factors from a new perspective of the movement path of financial customers. For this analysis, the network between administrative districts, which form the fundamental unit of a location, was analyzed based on the financial transactional data. The important findings of this study are as follows. First, in conformity with the previous studies, the income level, the spending level, the number of businesses, and the size of workforce in the pertinent region were all found to influence the size of a bank's market. Second, the centrality index extracted from the analysis of the network was found to have a significant effect on the locations of bank branches. In particular, the degree centrality was revealed to have a greater influence on the size of a bank's market than does the closeness centrality. Such results of this study clearly suggest the needs for a new approach from the perspective of network in furtherance of other factors that have been considered important in the previous studies of the distribution network strategies.

    We provide here unique data on elephant skeletal ontogeny. We focus on the sequence of cranial and post-cranial ossification events during growth in the African elephant (Loxodonta africana). Previous analyses on ossification sequences in mammals have focused on monotremes, marsupials, boreoeutherian and xenarthran placentals. Here, we add data on ossification sequences in an afrotherian. We use two different methods to quantify sequence heterochrony: the sequence method and event-paring/Parsimov. Compared with other placentals, elephants show late ossifications of the basicranium, manual and pedal phalanges, and early ossifications of the ischium and metacarpals. Moreover, ossification in elephants starts very early and progresses rapidly. Specifically, the elephant exhibits the same percentage of bones showing an ossification centre at the end of the first third of its gestation period as the mouse and hamster have close to birth. Elephants show a number of features of their ossification patterns that differ from those of other placental mammals. The pattern of the initiation of the ossification evident in the African elephant underscores a possible correlation between the timing of ossification onset and gestation time throughout mammals.

  6. Earth Science World ImageBank (ESWIB): A Comprehensive Collection of Geoscience Images Being Developed by the American Geological Institute

    NASA Astrophysics Data System (ADS)

    Howe, A. W.; Keane, C. M.

    2003-12-01

    Although there are geoscience images available in numerous locations around the World Wide Web, there is no universal comprehensive digital archive where teachers, students, scientists, and the general public can gather images related to the Earth Sciences. To fill this need, the American Geological Institute (AGI) is developing the largest image database available: the Earth Science World ImageBank (ESWIB). The goal of ESWIB is to provide a variety of users with free access to high-quality geoscience images and technical art gathered from photographers, government organizations, and scientists. Each image is cataloged by location, author, image rights, and a detailed description of what the image shows. Additionally, images are cataloged using keywords from AGI's precise Georef indexing methodology. Students, teachers, and the general public can search or browse and download these images for use in slide show presentations, lectures, papers, or for other educational and outreach uses. This resource can be used for any age level, in any kind of educational venue. Users can also contribute images of their own to the database through the ESWIB website. AGI is scanning these images at a very high resolution (16 x 20 inches) and depending on the author's rights, is making high-resolution copies (digital or print) available for non-commercial and commercial purposes. This ImageBank is different from other photo sites available in that the scope has more breadth and depth than other image resources, and the images are cataloged with a very high grade of detail and precision, which makes finding needed images fast and easy. The image services offered by ESWIB are also unique, such as the low-cost commercial options and high quality image printouts. AGI plans on adding more features to ESWIB in the future, including connecting this resource to the up-coming online Glossary of Geology, a geospatial search option, using the images to make generic PowerPoint presentations

  8. The politics of African energy development: Ethiopia's hydro-agricultural state-building strategy and clashing paradigms of water security.

    PubMed

    Verhoeven, Harry

    2013-11-13

    As key economic, ecological and demographic trends converge to reshape Africa and its relationship with the outside world, a new politics is emerging in the twenty-first century around the water-food-energy nexus, which is central to the continent's relevance in the global economy. On the one hand, Malthusian anxieties are proliferating; pessimists link population growth and growing water scarcity to state failure and 'water wars'. On the other hand, entrepreneurs, sovereign wealth funds and speculators consider Africa's potential in water resources, energy production and food output as one of the last great untapped opportunities for the global economy: Africa is on the brink of an agro-industrial transformation. This article examines how African actors are not merely responding to economic and environmental changes but also thinking politically about water, food and energy security. Many of them are seizing the new opportunities to redefine their national politics, their relationship with local communities and their ties with external players, regionally and globally. Ethiopia's project of hydro-agricultural state-building helps to identify the most important fault lines of this new politics at the national, local and international level. The politics of water security and energy development simultaneously puts African states and their populations on the defensive, as they grapple with huge challenges, but also provides them with unique opportunities to take advantage of a more favourable global configuration of forces.

    Childhood obesity has reached epidemic proportions and is linked to hypertension among African American youth. Optimistic bias influences behavior of youth causing them to underestimate their susceptibility to negative health outcomes. This study explored adolescent behaviors and prevalence of high blood pressure and obesity in a school district. We examined the relationship between individual health risk practices and optimistic bias on health outcomes; 433 African American high school students were administered a survey and had their obesity and blood pressure measured by the school nurse. Canonical correlational analyses were used to examine relationships between health risk practices and descriptive statistics for optimistic bias and health outcomes. Engaging in moderate exercise for at least 30 min in the last 7 days and lower blood pressure was the only statistically significant relationship. Two-thirds of the students did not perceive themselves to be at risk of developing cardiovascular disease with males at greater risk than females, despite the presence of clinical risk factors for hypertension and obesity. Reducing health optimistic bias is an effective way of motivating young people to adopt more positive behaviors using educational institutions to implement intervention programs that promote positive health behavior as a way to reduce health disparities.

    Introduction Increasing efforts are being made globally on capacity building. North-south research partnerships have contributed significantly to enhancing the research capacity in low- and middle-income countries (LMICs) over the past few decades; however, a lack of skilled researchers to inform health policy development persists, particularly in LMICs. The EU FP7 funded African/Asian Regional Capacity Development (ARCADE) projects were multi-partner consortia aimed to develop a new generation of highly trained researchers from universities across the globe, focusing on global health-related subjects: health systems and services research and research on social determinants of health. This article aims to outline the successes, challenges and lessons learned from the life course of the projects, focusing on the key outputs and experiences of developing and implementing these two projects together with sub-Saharan African, Asian and European institution partners. Design Sixteen participants from 12 partner institutions were interviewed. The data were analysed using thematic content analysis, which resulted in four themes and three sub-categories. These data were complemented by a review of project reports. Results The results indicated that the ARCADE projects have been successful in developing and delivering courses, and have reached over 920 postgraduate students. Some partners thought the north-south and south-south partnerships that evolved during the project were the main achievement. However, others found there to be a 'north-south divide' in certain aspects. Challenges included technical constraints and quality assurance. Additionally, adapting new teaching and learning methods into current university systems was challenging, combined with not being able to award students with credits for their degrees. Conclusion The ARCADE projects were introduced as an innovative and ambitious project idea, although not designed appropriately for all partner institutions

    2010-01-01

    The present study tested Abidin’s (1992) parenting stress model in a sample of low-income African American fathers and their toddlers, specifically examining the mediation effect of fathers’ engagement (self-report and observed) on the association between parenting stress and children’s social competence and problem behavior. We found that fathers reported moderate levels of parenting stress, but we found no evidence of a direct effect of stress on children’s social development. However, parenting stress predicted more engagement in management, which predicted children’s increased problem behaviour. These findings highlight the effect of fathering stress on specific forms of father engagement that affect toddlers’ social development. PMID:20190875

    South Africa urgently needs HIV prevention interventions that can be disseminated for use in clinical and community settings. A brief theory-based HIV risk reduction counselling intervention originally developed in the USA has recently been adapted for use in a South African sexually transmitted infection clinic. The 60-minute risk reduction counselling intervention was grounded in the Information-Motivation-Behavioural Skills (IMB) model of HIV preventive behaviour change, adapted through a series of interdisciplinary collaborative workshops. This paper reports the process of developing and culturally adapting the brief risk reduction counselling intervention. The processes used for adapting the HIV risk reduction counselling for South Africa provides a potential model for conducting technology transfer activities with other HIV prevention interventions. Several lessons learned from this process may help guide future efforts to transfer HIV prevention technologies.

    In this article we summarize work with poor, inner-city Hispanic and African American families conducted at the University of Miami Center for Family Studies. We elucidate ways in which this research program has paralleled the treatment development paradigm and has been responsive to changes in local demographics. Specific cultural issues pertaining to Hispanics and African Americans are discussed in light of treatment development and implementation. Future directions and challenges for working with poor, inner-city minority families are addressed. PMID:15293648

    If the therapeutic potential of stem cell-based therapies is ever realized, demand for stem cells and derivative tissues will be tremendous and will create new challenges for health care systems, especially publicly funded health care systems. We propose a framework for the ethical analysis of stem cell research and development that considers the welfare of communities, tissue recipients, and cell sources in relation to a range of stem cell production and distribution options. Ethical desiderata include: equitable access, maximized potential therapeutic benefit across demographic and disease groups, and reasonable cost. Other ethical priorities include the minimization of stem cell line and tissue wastage, risk of immune rejection, risk of transmitting diseases, the use of human embryos, and risk to those contributing source cells. We array plausible sources of stem cells and distribution strategies to characterize 12 potential models for producing and distributing cells and tissues in the future. We describe "personalized", "matched", and "universalized" models, and compare the ethical acceptability of these models. Popular and scientific discourses about stem cells typically emphasize personalized or matched stem cell distribution models. We show that universalized models may ultimately best serve the interest of taxpayers, communities and patients who hold high stakes in the therapeutic success of stem cell science. They are therefore highly worthy of scientific pursuit. This conclusion is provisional and the framework must be reapplied as scientific knowledge, technological capacity and ethical mores evolve.

    Background There is a critical need to expand the pool of available kidneys for African Americans who are on the transplant wait-list due to the disproportionally lower availability of deceased donor kidneys compared with other races/ethnic groups. Encouraging living donation is one method to fill this need. Incorporating mHealth strategies may be a way to deliver educational and supportive services to African American transplant-eligible patients and improve reach to those living in remote areas or unable to attend traditional group-session-based programs. Before program development, it is essential to perform formative research with target populations to determine acceptability and cultivate a patient-centered and culturally relevant approach to be used for program development. Objective The objectives of this study were to investigate African American kidney transplant recipients’ and kidney donors’/potential donors’ attitudes and perceptions toward mobile technology and its viability in an mHealth program aimed at educating patients about the process of living kidney donation. Methods Using frameworks from the technology acceptance model and self-determination theory, 9 focus groups (n=57) were administered to African Americans at a southeastern medical center, which included deceased/living donor kidney recipients and living donors/potential donors. After a demonstration of a tablet-based video education session and explanation of a group-based videoconferencing session, focus groups examined members’ perceptions about how educational messages should be presented on topics pertaining to the process of living kidney donation and the transplantation. Questionnaires were administered on technology use and perceptions of the potential program communication platform. Transcripts were coded and themes were examined using NVivo 10 software. Results Qualitative findings found 5 major themes common among all participants. These included the following: (1

    Ctenocephalides felis (Bouché, 1835) commonly called "cat's flea" presents two recognized subspecies: Ctenocephalides felis strongylus (Jordan, 1925), observed in the African continent, and Ctenocephalides felis felis (Bouché, 1835) in the other regions (North Africa, Europe and America) (Ménier and Beaucournu, 19991. In sub-Saharan Africa, the principal flea found in the pets and certain livestock (ovine, caprine and bovine), belongs to the subspecies C. f. strongylus. Some bio-ecologic parameters of C. f. strongylus were studied in various conditions of breeding and the results compared with those currently available for C. f. felis. At 75% +/- 5 of relative humidity, the development cycle of C. f. strongylus lasts 20-21 days at 27 degrees C and 16 to 17 days at 29 degrees C. In comparison with C. f. felis, it is shown that for identical breeding temperatures, the African subspecies of the cat flea develops itself slowly. This difference could be explained by the influence of the climate of their respective areas of distribution on their development cycle. With 75% +/- 5 of relative humidity, C. f. strongylus cannot survive more than 14 days in temperatures ranging between 27 and 29 degrees C, and this without any blood meal. Under the same conditions, this duration of survival does not exceed 16 days at 19 degrees C. But when C. f. strongylus has taken a first blood meal, its lifespan is much shorter when it is out of its host. Indeed, no individual is found living three days passed out of the fur of its host at 29 degrees C, five days at 27 degrees C and eight days at 19 degrees C. It is the same for C. f. felis. These data on bio-ecology of C. f. strongylus enable to understand the influence of temperature on its development cycle and consider more efficient strategies of control.

    1995-12-01

    This study examined data from an alternative school among African-American pregnant and parenting teenagers in order to gauge the extent to which mentors were associated with positive educational and career outcomes. Interviews were conducted during 1992-93 among most who were attending the school at that time. The study included 204 African-American adolescents aged 11-19 years. 61% were expecting their first birth, 34% had a child already, and 5% had 2 or more prior children. No one was ever married. 66.2% lived on welfare benefits. A mentor is one who was an older adult, who was someone the child could count on, who believed or cared deeply about the child, who inspired the child to do the best, and the relationship affected the choices made. Mentors are looked up to as role models for the kind of person one would like to be or for the kind of career one would like to have. Study participants rated mentors on a scale of 1-5 on each characteristic. Other measures include the occupational aspiration-expectation gap, career related activities, opportunity structure beliefs, and life optimism. Findings show that 57.8% had adult mentors, and 46.3% knew their mentors for at least 15 years or more. 80% expected to maintain their relationship with the mentor indefinitely. 32% nominated aunts, and 25.7% nominated grandmothers. 47.7% reported seeing mentors daily. 48% saw their mentors at least once a week. 66% reported expectations that were equal to aspirations. The path analysis indicates that all paths between career activities, beliefs about opportunities, and life optimism were significantly associated with mentor support. The model suggests that increased life optimism from mentor support may directly and indirectly lead to beliefs in education as an opportunity structure and career related activities. The authors suggest encouraging adolescents to reach out to supportive adults.

    One way of developing culturally relevant health communication in the African American church setting is to develop spiritually based interventions, in which the health message is framed by relevant spiritual themes and scripture. In this article we describe the development of a community health advisor (CHA)-led intervention aimed at increasing informed decision making (IDM) for prostate cancer screening among church-attending African American men. Full-color print educational booklets were developed and pilot tested with extensive community participation of church-attending African American men age-eligible for screening. The intervention development phase consisted of ideas solicited from an advisory panel of African American men (N = 10), who identified core content and developed the spiritual themes. In the intervention pilot testing phase, prototypes of the intervention materials were pilot tested for graphic appeal in two focus groups (N = 16), and content was tested for acceptability and comprehension using individual cognitive response interviews (N = 10). Recommendations were made for project branding and logo and for use of graphics of real people in the educational materials. Significant feedback was obtained from the focus groups, on the graphics, colors, fonts, continuity, titles, and booklet size/shape. The importance of working closely with the community when developing interventions is discussed, as well as the importance of pilot testing of educational materials. PMID:19731129

    2013-01-01

    Introduction Disability and Physical Function (PF) outcome assessment has had limited ability to measure functional status at the floor (very poor functional abilities) or the ceiling (very high functional abilities). We sought to identify, develop and evaluate new floor and ceiling items to enable broader and more precise assessment of PF outcomes for the NIH Patient-Reported-Outcomes Measurement Information System (PROMIS). Methods We conducted two cross-sectional studies using NIH PROMIS item improvement protocols with expert review, participant survey and focus group methods. In Study 1, respondents with low PF abilities evaluated new floor items, and those with high PF abilities evaluated new ceiling items for clarity, importance and relevance. In Study 2, we compared difficulty ratings of new floor items by low functioning respondents and ceiling items by high functioning respondents to reference PROMIS PF-10 items. We used frequencies, percentages, means and standard deviations to analyze the data. Results In Study 1, low (n = 84) and high (n = 90) functioning respondents were mostly White, women, 70 years old, with some college, and disability scores of 0.62 and 0.30. More than 90% of the 31 new floor and 31 new ceiling items were rated as clear, important and relevant, leaving 26 ceiling and 30 floor items for Study 2. Low (n = 246) and high (n = 637) functioning Study 2 respondents were mostly White, women, 70 years old, with some college, and Health Assessment Questionnaire (HAQ) scores of 1.62 and 0.003. Compared to difficulty ratings of reference items, ceiling items were rated to be 10% more to greater than 40% more difficult to do, and floor items were rated to be about 12% to nearly 90% less difficult to do. Conclusions These new floor and ceiling items considerably extend the measurable range of physical function at either extreme. They will help improve instrument performance in populations with broad functional ranges and those concentrated at

    2012-03-01

    The present study examined perceptions of racial discrimination and racial socialization on racial identity development among 566 African American adolescents over 3 years. Latent class analyses were used to estimate identity statuses (Diffuse, Foreclosed, Moratorium, and Achieved). The probabilities of transitioning from one stage to another were examined with latent transition analyses to determine the likelihood of youth progressing, regressing, or remaining constant. Racial socialization and perceptions of racial discrimination were examined as covariates to assess the association with changes in racial identity status. The results indicated that perceptions of racial discrimination were not linked to any changes in racial identity. Youth who reported higher levels of racial socialization were less likely to be in Diffuse or Foreclosed compared with the Achieved group.

    Egg rotation and centrifugation experiments strongly suggest a role for gravity in the determination of the spatial structure of amphibian embryos. Decisive experiments can only be made in Space. Eggs of Xenopus laevis, the South African clawed toad, were the first vertebrate eggs which were successfully fertilized on Sounding Rockets in Space. Unfixed, newly fertilized eggs survived reentry, and a reasonable number showed a seemingly normal gastrulation but died between gastrulation and neurulation. Only a few reached the larval stage, but these developed abnormally. In the future, we intend to test whether this abnormal morphogenesis is due to reentry perturbations, or due to a real microgravity effect, through perturbation of the reinitiation of meiosis and other processes, or started by later sperm penetration.

    A suite of tetra-nucleotide microsatellite loci were developed for the invasive giant African land snail, Achatina (=Lissachatina) fulica Bowdich, 1822, from Ion Torrent next-generation sequencing data. Ten of the 96 primer sets tested amplified consistently in 30 snails from Miami, Florida, plus 12 individuals representative of their native East Africa, Indian and Pacific Ocean regions. The loci displayed moderate levels of allelic diversity (average 5.6 alleles/locus) and heterozygosity (average 42 %). Levels of genetic diversity were sufficient to produce unique multi-locus genotypes and detect phylogeographic structuring among regional samples. The invasive A. fulica can cause extensive damage to important food crops and natural resources, including native flora and fauna. The loci characterized here will be useful for determining the origins and tracking the spread of invasions, detecting fine-scale spatial structuring and estimating demographic parameters.

    Abstract Objectives The purpose of the current study was to develop and evaluate the psychometric properties of a culturally- and stage-of-disease-appropriate measure of complementary and alternative medicine (CAM) use among a population of African-American individuals with acquired immune deficiency syndrome (AIDS) using a mixed-method design. Design Data were collected in two phases. In phase 1, qualitative data were used to refine an existing CAM measure for the specific study population in the present study. In phase 2, this refined instrument was implemented in a larger sample. The resulting numeric data were analyzed to evaluate the psychometric properties of the revised CAM instrument. Setting Data were collected from patients who were receiving care from the infectious disease clinic of a large, public, urban hospital in the Southeastern United States. Subjects Patients were eligible to participate if they (1) were receiving their care from the clinic, (2) had an AIDS diagnosis, (3) were identified as African-American, (4) were ≥21 years of age, (5) spoke English, and (6) were not cognitively impaired. Measures Focus groups in phase 1 were conducted with a semistructured focus group guide. Participants also completed a basic sociodemographic survey. Phase 2 participants used programmed laptops to answer questions about their CAM use and several sociodemographic questions. Results Information from the focus groups prompted some substantive revisions in the already-existing CAM survey. The revised instrument had satisfactory face validity and adequate test–retest reliability (r = 0.79). Furthermore, the instrument factored in a manner that was interpretable and consistent with prior findings. Conclusions In order for human immunodeficiency virus health care providers to provide the best care to their patients, they need to be informed about the types and frequency of CAM use among their patients. This can be accomplished by methodologically developing

    2014-12-01

    Low-income, urban African American (AA) girls are at heightened risk for sexually transmitted infections (STIs), and violence exposure may be an important risk factor. AA girls (N = 177) from low-income communities in Chicago completed a 2-year longitudinal study of HIV-risk behavior involving five waves of data collection (ages 12-16 at baseline) and a sixth wave (ages 14-22) assessing lifetime trauma and victimization history. Childhood exposure to violence (CEV) represented reports of physical, sexual, or witnessed violence before age 12. Latent growth curve analysis examined CEV as a covariate of sexual experience, number of sexual partners, and inconsistent condom use trajectories. CEV was associated with greater sexual risk, although the pattern differed across the three outcomes. Overall, findings emphasize the need for early interventions to reduce sexual risk among low-income urban girls who have experienced violence. Efforts to address or prevent violence exposure may also reduce rates of STIs in this population.

    Background Pedigree development, family history, and genetic testing are thought to be useful in improving outcomes of chronic illnesses such as hypertension (HTN). However, the clinical utility of pedigree development is still unknown. Further, little is known about African Americans’ (AAs’) perceptions of family history and genetic testing. Aims This study examined the feasibility of developing pedigrees for AAs with HTN and explored perceptions of family history and genetic research among AAs with HTN. Methods The US Surgeon General’s My Family Health Portrait was administered, and 30–60 minute in-person individual interviews were conducted. Descriptive statistics were used to analyze pedigree data. Interview transcripts were analyzed with content analysis and constant comparison. Results Twenty-nine AAs with HTN were recruited from one free clinic (15 women, 14 men; mean age 49 years, SD 9.6). Twenty-six (90%) reported their family history in sufficient detail to develop a pedigree. Perceptions of family history included knowledge of HTN in the family, culturally influenced family teaching about HTN, and response to family history of HTN. Most participants agreed to future genetic testing and DNA collection because they wanted to help others; some said they needed more information and others expressed a concern for privacy. Conclusion The majority of AAs in this sample possessed extensive knowledge of HTN within their family and were able to develop a three generation pedigree with assistance. The majority were willing to participate in future genetic research. PMID:25322748

Design A literature review guided framework development of grief/loss. New items were created from focus groups. Items were revised based on expert review and patient feedback and were then field tested. Analyses included confirmatory factor analysis (CFA), graded response IRT modeling and evaluation of differential item functioning (DIF). Setting We tested a 20-item pool at several rehabilitation centers across the United States, including the University of Michigan, Kessler Foundation, Rehabilitation Institute of Chicago, the University of Washington, Craig Hospital and the James J. Peters/Bronx Department of Veterans Affairs hospital. Participants A total of 717 individuals with SCI answered the grief and loss questions. Results The final calibrated item bank resulted in 17 retained items. A unidimensional model was observed (CFI = 0.976; RMSEA = 0.078) and measurement precision was good (theta range between −1.48 to 2.48). Ten items were flagged for DIF, however, after examination of effect sizes found this to be negligible with little practical impact on score estimates. Conclusions This study indicates that the SCI-QOL Grief and Loss item bank represents a psychometrically robust measurement tool. Short form items are also suggested and computer adaptive tests are available. PMID:26010969

  12. Cord blood banking.

    PubMed

    Cord blood (CB) is a unique product, rich in haemopoietic stem cells (HSC), that is currently used in the transplantation setting to restore haemopoiesis. It restores haemopoietic stem cell function in patients suffering from malignancies, bone marrow (BM) failure disorders and inherited metabolic and immunological disorders. Related and unrelated CB donations have been successfully transplanted in both the paediatric and adult settings. CB, previously considered a waste product, can be collected from both vaginal deliveries and caesarean sections, either in utero or ex utero, at no risk to the donor, processed to remove excess plasma and red cells, cryopreserved, tested, HLA-typed and stored to provide an 'off-the-shelf' product. CB has a lower risk of some important viral infections and a lower incidence and severity of acute and chronic graft versus host disease (GvHD) than BM. CB transplantation is under innovative development and international collaborative studies are investigating ways to improve transplant outcomes. Other uses for CB remain speculative and it is premature to speculate whether non-haemopoietic stem cells are present in cord blood in sufficient numbers for use against degenerative conditions, as is currently postulated by some commercial organisations. Cord blood banking in EU member countries is now regulated by an EU Directive, which provides a statutory basis for regulation safety to ensure efficacy. Compliance is required by 2006. It requires that all banking establishments are inspected and accredited by a Competent Authority. This includes public altruistic banking as well as directed banking activities.

    Transplantation of cord blood stem cells is a new and rapidly developing area. It has been used as a treatment for many diseases such as hematologic malignancies, primary immune deficiencies and metabolic diseases. Recently, stem cells have been used in regenerative medicine, particularly in neurodegenerative and cardiovascular diseases. For these reasons interest has been growing in banking cord blood. To be able to find an acceptable donor for any recipient in need, it is necessary to have on stock a great diversity of cells with different genetic types from different populations. Networks of banks and registries have been created around the world in order to share and exchange transplants. Public banks organize collection for altruistic donor of cord blood for unrelated hematopoietic stem cell transplantation and for directed donation in families at risk. But there are increasing numbers of families that are requesting storage of cord blood for possible future therapeutic use in the family. Establishment of cord blood banks has raised a number of important scientific, legal, ethical and political issues, which are discussed in this paper.

    Astrocyte morphologies and heterogeneity were described in male African giant rats (AGR; Cricetomys gambianus, Waterhouse) across three age groups (five neonates, five juveniles, and five adults) using Silver impregnation method and immunohistochemistry against glial fibrillary acidic protein. Immunopositive cell signaling, cell size and population were least in neonates, followed by adults and juveniles, respectively. In neonates, astrocyte processes were mostly detected within the glia limitans of the mid and hind brain; their cell bodies measuring 32 ± 4.8 μm in diameter against 91 ± 5.4 μm and 75 ± 1.9 μm in juveniles and adults, respectively. Astrocyte heterogeneity in juvenile and adult groups revealed eight subtypes to include fibrous astrocytes chiefly in the corpus callosum and brain stem, protoplasmic astrocytes in the cortex and dentate gyrus (DG); radial glia were found along the olfactory bulb (OB) and subventricular zone (SVZ); velate astrocytes were mainly found in the cerebellum and hippocampus; marginal astrocytes close to the pia mater; Bergmann glia in the molecular layer of the cerebellum; perivascular and periventricular astrocytes in the cortex and third ventricle, respectively. Cell counts from twelve anatomical regions of the brain were significantly higher in juveniles than in adults (p ≤ 0.01) using unpaired student t-test in the cerebral cortex, pia, corpus callosum, rostral migratory stream, DG, and cerebellum. Highest astrocyte count was found in the DG, while the least count was in the brain stem and sub cortex. Astrocytes along the periventricular layer of the OB are believed to be part of the radial glia system that transport newly formed cells towards the hippocampus and play roles in neurogenesis migration and homeostasis in the AGR. Therefore, astrocyte heterogeneity was examined across age groups in the AGR to determine whether age influences astrocytes population in different regions of the AGR brain and discuss possible

  15. Shared Platform for South African Earth and Environmental Observation Systems: Recent Developments and Improvements

    Over the past 3 years, SAEON has worked with a number of stakeholders and funders to establish a shared platform for the management of dissemination of E&EO research outputs, data sets, and services. This platform is strongly aligned with GEO principles and architecture, allowing direct integration with the GEOSS Broker. The platform has two important characteristics: 1. It reduces the cost and lead time of provision of similar infrastructure for future initiatives. 2. The platform is domain-agnostic to some degree, and can be used for non E&EO applications. Projects to achive this is under way at present. The paper describes the application of the platform for a variety of user communities and initiatives (SAEON Data Portal, South African Earth Observation System, Risk and Vulnerability Atlas, BioEnergy Atlas, National Spatial Information Framework, ICSU World Data System Components, and many more), and demonstrates use cases utilising a distributed, service oriented architecture. Significant improvements have been made to the interoperability functions available to end users and content providers, and these are demonstrated and discussed in detail. Functions include • Creation and persistence of composite maps, as well as time series or scatter charts, supporting a variety of standardized data sources. • Search facilities have been extended to allow analysis and filtering of primary search results, and to deal with large meta-data collections. • In addition, data sources, data listings, news items, images, search results, and other platform content can, with increasing flexibility, be accessed as standardized services that are processed in standardized clients, allowing creation of a rich user interface, and permitting the inclusion of platform functionality into external websites and resources. This shift to explicit service-oriented, peer-to-peer architecture is a preparation for increased distributed processing and content composition, and will support

  16. Corneal grafting and banking.

    2009-01-01

    Corneal transplantation was conceptualized at the end of the 18th century, but it took more than 100 years before human corneal grafting was introduced. The greatest step forward was the demonstration by Filatov that corneal tissue can be collected and used post mortem. The history of eye banking includes the development of preservation techniques. Storage in cold to minimize microbial growth and tissue disintegration was first choice but during the last 30 years this has been taken over by warm storage (organ culture) where the donor cornea proves its sterility and vitality before being transferred to the recipient. The long-term organ culture storage makes exchange between centres possible and allows for histocompatibility matching. The internationalization led to the establishing of the European Eye Bank Association but also to an increasing number of governmental regulations. Developments in years to come may lead to control of graft biomechanics and optics. This technical development tends to favour a centralization.

    Reducing new HIV/STD infections among at-risk adolescents requires developing and evaluating evidence-based health communication approaches. Research overwhelmingly supports the conclusion that early sexual initiation is associated with STDs and other negative outcomes in later years (e.g., unintended pregnancy). The authors' research group secured funding from the National Institute of Mental Health to develop, implement, and rigorously evaluate televised mass media campaigns to delay initiation of sexual intercourse among African American and White adolescents in two cities in the Southeastern United States. The focus of the present study is on the development and implementation of the campaigns, including (a) rationale and theoretical underpinnings; (b) collection, screening, and assessment of existing public service announcements; (c) development of new public service announcements; (d) study design and campaign airing plan; and (e) message exposure achieved in the campaigns. Health communication campaigns hold much promise in reaching at-risk adolescent populations with targeted, timely, and relevant risk-reduction messages.

    The following dissertation reports on a qualitative exploration that serves two main goals: (1) to qualitatively define and highlight science motivation development of Black/African American and Latina/o students as they learn science in middle school, high school, and in college and (2) to reveal through personal narratives how successful entry and persistence in science by this particular group is linked to the development of their science identities. The targeted population for this study is undergraduate students of color in science fields at a college or university. The theoretical frameworks for this study are constructivist theory, motivation theory, critical theory, and identity theories. The methodological approach is narrative which includes students' science learning experiences throughout the course of their academic lives. I use The Science Motivation Questionnaire II to obtain baseline data to quantitatively assess for motivation to learn science. Data from semi-structured interviews from selected participants were collected, coded, and configured into a story, and emergent themes reveal the important role of science learning in both informal and formal settings, but especially in informal settings that contribute to better understandings of science and the development of science identities for these undergraduate students of color. The findings have implications for science teaching in schools and teacher professional development in science learning.

    Structural barriers constrain marginalized youths' development of work salience and vocational expectations. Sociopolitical development (SPD), the consciousness of, and motivation to reduce, sociopolitical inequality, may facilitate the negotiation of structural constraints. A structural model of SPD's impact on work salience and vocational expectations was proposed and its generalizability tested among samples of low-socioeconomic-status African American, Latin American, and Asian American youth, with Educational Longitudinal Study data. Measurement and temporal invariance of these constructs was first established before testing the proposed model across the samples. Across the three samples, 10th-grade SPD had significant effects on 10th-grade work salience and vocational expectations; 12th-grade SPD had a significant effect on 12th-grade work salience. Tenth-grade SPD had significant indirect effects on 12th-grade work salience and on 12th-grade vocational expectations for all three samples. These results suggest that SPD facilitates the agentic negotiation of constraints on the development of work salience and vocational expectations. Given the impact of adolescent career development on adult occupational attainment, SPD may also foster social mobility among youth constrained by an inequitable opportunity structure.

    The relative contribution of pubertal timing and tempo to the development of depression has not been tested in a large, representative sample, nor has the interface among pubertal maturation, depression, and race been tested. Participants were a community-based sample of 2,450 girls from the Pittsburgh Girls Study who were interviewed annually from ages 9 to 17 years. Pubertal timing and tempo were characterized as a unitary construct and also separately for pubic hair and breast development using child and maternal report. Depression symptoms were assessed annually. African American girls had higher depression symptoms and progressed through puberty earlier, but at a slower tempo than European American girls. Girls with earlier timing had higher levels of depression symptoms at age 10 years. Slower tempo was associated with higher depression symptoms at age 10, and faster tempo was associated with increases in depression from ages 10 to 13. As well, race moderated the associations among timing, tempo, and depression symptoms, and the association between race and depression was partially mediated by pubertal timing and tempo. Pubertal timing and tempo and race contribute to the developmental course of depression from early to late adolescence. The pattern of association varies as a function of the developmental window within which depression is assessed. Thus, repeated measures of depression symptoms and puberty across the span of pubertal development are necessary for exploring the relative importance of dimensions of pubertal development to depression etiology.

    This article examines recent World Bank reports on the role of the state in the development process, with particular reference to the rise of the East Asian newly industrializing countries and the crisis of "governance" in sub-Saharan Africa. The concepts of market friendly intervention and good governance are critically discussed, and are found to be inadequate as explanations for East Asian "success" and African "failure." The author presents an alternative explanation for the rise of the newly industrializing countries, which draws out some of the implications for the developing world.

  2. Concepts of marine specimen banking.

    1997-05-01

    For more than a decade environmental specimen banking (ESB) has been an established approach for monitoring and retrospective environmental survey purposes in a number of developed countries. Specimen banking is carried out on regional or national scales for various environmental materials. The ecological or problem-oriented approach, as pursued e.g. in Germany or USA has the advantages of a restricted survey and a clear political mandate. Environmental problems, however, are by no means national or regional issues, since the diversity and dispersion of hazardous substances make environmental monitoring clearly a global affair. The structuring of our environment suggests that banking should not be limited by national boundaries, but rather be based on eco-systematic principles. Such distinct banking efforts should be devoted to the monitoring of physico-chemical aspects of climatic change and air pollution, soil quality, and aquatic monitoring on a world-wide scale. As some experience already exists with specialized banking programs for marine samples, such as the National Marine Mammal Tissue Bank or the Mussel Watch Program in the United States, an international marine specimen bank, based on principles of national ESB's, is advocated to be established in due time. Following the recommendations of the 1992 Rio 'Earth Summit' to pursue sustainable development strategies, such an establishment could strongly facilitate efforts concerning pollution control and mitigation, overexploitation and mining of ocean resources on a regional or global scale.

    1995-06-01

    This paper explores the socioeconomic obstacles to HIV prevention and treatment in developing countries. The opening sections explain the historical origins of structural adjustment programs and their characteristics. Structural adjustment programs undermine the social fabric of many developing countries, and potentially promote behaviors which place people at increased risk of HIV infection. The authors discuss the declining sustainability of the rural subsistence economy, development of a transportation infrastructure, migration and urbanization, and reductions in spending on health and social services. Social and economic interventions are needed to stem the spread of HIV and care for those who are already infected. While a substantial amount of biomedical research has been conducted, socioeconomic aspects of the AIDS epidemic have often been ignored. For HIV transmission in developing countries to be substantially reduced, economic policies which may have promoted the spread of disease must be modified. An alternative development strategy consists of satisfying people's basic human needs, shifting from an export-driven economy to diversified agricultural production in the interest of securing regional self-sufficiency, supporting marginal producers and subsistence farmers, and placing greater emphasis upon human resource development in developing countries. Moreover, the IMF and World Bank need to change their policy to one which is truly about cooperative development, while the charters of the IMF and World Bank need to be altered to permit the cancellation or rescheduling of debt. These institutions should also play a leading role in the restructuring of debt owed to private lenders.

    We describe the initiation and establishment of The University of Zambia - University College London Medical School (UNZA-UCLMS) Research and Training Project, an entirely African scientist-led, south-north partnership. In its 16 year existence, the project, by successfully obtaining competitive grant funding, has transformed itself into one of Africa's most productive African-led R&D programmes with training and visible research outputs. The project serves as a role model and now networks R&D and training activities with six southern African (10 institutions) and six European countries. This project case study illustrates that deep commitment is essential for success and that the factors which facilitate success in R&D in Africa need to be evaluated. The long-term prospects for sustaining the UNZA-UCLMS Project appear bright and are dependent on several factors: the ability to retain trained African scientists; obtaining continued competitive or donor grant funding support; and serious investment by the African governments involved. The recent 255 million Euros EDCTP investment in sub-Saharan Africa through south-north partnerships is expected to enhance existing African-led R&D programmes. African governments and scientists must rise to the challenge.

    This research team has designed and implemented 2 culturally relevant, Internet-enhanced physical activity (PA) interventions for overweight/obese African-American female college students. Presumably, these are the only prospectively designed, culturally relevant interventions using the Internet to promote PA among African-American women. Due to the limited research on this topic, the experiences associated the design and implementation of these studies were syntesized and 5 key lessons learned from this research were formulated. Findings provide insight for researchers to consider when developing Internet-based PA promotion interventions for African-American women. Lessons learned included: 1) Elicit and incorporate feedback from the target population throughout development of an Internet-based PA promotion tool; 2) Incorporate new and emerging technologies into Internet-enhanced PA programs; 3) Maintain frequent participant contact and provide frequent incentives to promote participant engagement; 4) Supplement Internet-based efforts with face-to-face interactions; 5) Include diverse images of African-American women and culturally relevant PA-related information in Internet-based PA promotion materials.

    Because DC magnets consume a huge amount of electricity (resistive DC magnet) or liquid helium (superconducting magnet), a capacitor-bank-driven pulsed magnet is known to be a cost-effective way of generating high magnetic fields. This type of pulsed magnet is normally operated at liquid nitrogen temperature and consumes little electric power to generate over 50 tesla (T) during a short transient time of less than 50 millisecond (ms). With modern fast data acquisition systems, almost all kinds of physical quantities, such as photoluminescence, magnetization or resistance can be measured during a short magnetic field pulse. We report a recently home-built capacitor-bankdriven pulsed magnetic field facility, in which a capacitor bank of 1.5-MJ maximum stored energy is utilized to generate pulsed magnetic fields up to 50 T with transient pulse time of 22 ms.

    The DORCA Applications study has been directed at development of a data bank management computer program identified as DORMAN. Because of the size of the DORCA data files and the manipulations required on that data to support analyses with the DORCA program, automated data techniques to replace time-consuming manual input generation are required. The Dynamic Operations Requirements and Cost Analysis (DORCA) program was developed for use by NASA in planning future space programs. Both programs are designed for implementation on the UNIVAC 1108 computing system. The purpose of this Executive Summary Report is to define for the NASA management the basic functions of the DORMAN program and its capabilities.

    It is evident that rabies continues to be a neglected tropical disease; however, a recent global drive aims to eliminate canine-mediated human rabies by 2030. Global efforts have been vested into creating and developing resources for countries to take ownership of and overcome the challenges that rabies poses. The disconnect between the numbers of rabies cases reported and the numbers estimated by prediction models is clear: the key to understanding the epidemiology and true burden of rabies lies within accurate and timely data; poor and discrepant data undermine its true burden and negate the advocacy efforts needed to curb this lethal disease. In an effort to address these challenges, the Pan-African Rabies Control Network is developing a regional rabies-specific disease surveillance bulletin based on the District Health Information System 2 platform—a web-based, open access health information platform. This bulletin provides a data repository from which specific key indicators, essential to any rabies intervention program, form the basis of data collection. The data are automatically analyzed, providing useful outputs for targeted intervention. Furthermore, in an effort to reduce reporting fatigue, the data submitted, under authority from the respective governments, can automatically be shared with approved international authorities. The implementation of a rabies-specific bulletin will facilitate targeted control efforts and provide measurements of success, while also acting as a basis for advocacy to raise the priority of this neglected disease.

    African horse sickness (AHS) is considered a fatal re-emergent vector-borne disease of horses. In the absence of any effective treatment for AHS, vaccination remains the most effective form of disease control. The new generation of vaccines, such as one based on purified, inactivated AHS virus (AHSV, serotype 4), which does not induce antibodies against non-structural protein 3 (NS3), enables the development of diagnostic methods that differentiate infected from vaccinated animals (DIVA assays). As detecting AHS in AHSV-free countries may lead to restrictions on international animal movements and thereby cause significant economic damage, these DIVA assays are crucial for reducing movement restrictions. In this article, we describe a Luminex-based multiplex assay for DIVA diagnosis of AHS, and we validate it in a duplex format to detect antibodies against structural protein 7 (VP7) and NS3 in serum samples from horses vaccinated with inactivated AHSV4 vaccine or infected with a live virus of the same serotype. Results of the Luminex-based assay for detecting anti-NS3 antibodies showed good positive correlation with results from an in-house enzyme-linked immunosorbent assay (ELISA). Thus, the Luminex-based technique described here may allow multiplex DIVA antibody detection in a single sample in less than 2 h, and it may prove adaptable for the development of robust, multiplex serological assays.

    Episodic events of both Saharan dust outbreaks and African Easterly Waves (AEWs) are observed to move westward over the eastern tropical Atlantic Ocean. The relationship between the warm, dry, and dusty Saharan Air Layer (SAL) on the nearby storms has been the subject of considerable debate. In this study, the Weather Research and Forecasting (WRF) model is used to investigate the radiative effect of dust on the development of AEWs during August and September, the months of maximum tropical cyclone activity, in years 2003-2007. The simulations show that dust radiative forcing enhances the convective instability of the environment. As a result, most AEWs intensify in the presence of a dust layer. The Lorenz energy cycle analysis reveals that the dust radiative forcing enhances the condensational heating, which elevates the zonal and eddy available potential energy. In turn, available potential energy is effectively converted to eddy kinetic energy, in which local convective overturning plays the primary role. The magnitude of the intensification effect depends on the initial environmental conditions, including moisture, baroclinity, and the depth of the boundary layer. We conclude that dust radiative forcing, albeit small, serves as a catalyst to promote local convection that facilitates AEW development.

    Background African American youth are more likely than other racial and ethnic groups to be obese. African American youth are also more likely to live in disadvantaged neighborhoods which increase their victimization, observation, and fear of violence. Objectives This study tested if victimization, observation, and fear of violence in the neighborhood during adolescence predict trajectory of body mass index (BMI) in the 3rd decade of life in African Americans. Patients and Methods Data came from an 18-year community-based cohort. We used multi-group latent growth curve modeling for data analysis, considering neighborhood violence at age 15 (i.e. victimization, observation, and fear) as predictors, and the linear slope for the average change in BMI from age 21 to 32 as the outcome, with age and socioeconomic status (i.e. intact family and parental employment) as covariates. Results Fear of neighborhood violence at age 15 was predictive of an increase in BMI from age 21 to 32 among female but not male African Americans. Victimization and observation of violence at age 15 did not predict BMI change from age 21 to 32 among female or male African Americans. Conclusions Fear of neighborhood violence is a contributing factor to increased risk of obesity for female African American youth who live in disadvantaged areas. This finding has implications for prevention of obesity among African American women who are at highest risk for obesity in the United States. Initiatives that enhance neighborhood safety are critical strategies for obesity prevention among African American women. PMID:27679791

    At the University of Colorado, Dr. Gordon Meiklejohn pursed the study of influenza and other respiratory pathogens for an unbroken period of 40 years, under the auspices of the Commission on Influenza of the Armed Forces Epidemiological Board through a series of contracts with the U.S. Army Medical Research and Development Command. Sera, throat washings, and other specimens for diagnosis were sent to Dr. Meiklejohn's laboratory. After serologic and virologic studies were carried out, aliquots of sera and virus samples were logged in and frozen. Sera were stored at -20°C and virus specimens at -70°C. These specimens became known as the Denver Serum Bank. The Bank supported military research programs and other researchers nationally and internationally until the 1990s when lacking of funding and considerations of administration, space, and cost resulted in the destruction of all specimens.

    2011-01-01

    Background There is ample evidence in Asia and Latin America showing that past economic crises resulted in cuts in expenditures on health, lower utilization of health services, and deterioration of child and maternal nutrition and health outcomes. Evidence on the impact of past economic crises on health sector in Africa is lacking. The objectives of this article are to present the findings of a quick survey conducted among countries of the WHO African Region to monitor the effects of global financial crisis on funding for health development; and to discuss the way forward. Methods This is a descriptive study. A questionnaire was prepared and sent by email to all the 46 Member States in the WHO African Region through the WHO Country Office for facilitation and follow up. The questionnaires were completed by directors of policy and planning in ministries of health. The data were entered and analyzed in Excel spreadsheet. The main limitations of this study were that authors did not ask whether other relevant sectors were consulted in the process of completing the survey questionnaire; and that the overall response rate was low. Results The main findings were as follows: the response rate was 41.3% (19/46 countries); 36.8% (7/19) indicated they had been notified by the Ministry of Finance that the budget for health would be cut; 15.8% (3/19) had been notified by partners of their intention to cut health funding; 61.1% (11/18) indicated that the prices of medicines had increased recently; 83.3% (15/18) indicated that the prices of basic food stuffs had increased recently; 38.8% (7/18) indicated that their local currency had been devalued against the US dollar; 47.1% (8/17) affirmed that the levels of unemployment had increased since the onset of global financial crisis; and 64.7% (11/17) indicated that the ministry of health had taken some measures already, either in reaction to the global financing crisis, or in anticipation. Conclusion A rapid assessment, like the one

    Background Human African trypanosomiasis (HAT) is an infectious disease with a large global health burden occurring primarily in Central and Eastern Africa. Most current treatments have poor blood brain barrier (BBB) penetration, which prevent them from targeting the most lethal stage of the infection. In addition, current therapeutics suffer from a variety of limitations ranging from serious side effects to difficulties with treatment administration. Therefore it is of crucial importance to find new treatments that are safe, affordable, and effective against both sub-species of Trypanosoma brucei. Methods Semi-synthetic derivatization of the fungally-derived natural product merulin A (1) has led to the discovery of new development candidates for the protozoan parasite T. brucei, the causative agent of HAT. Creation of an initial SAR library based around the merulin scaffold revealed several key features required for activity, including the endoperoxide bridge, as well as one position suitable for further derivatization. Subsequent synthesis of a 20-membered analogue library, guided by the addition of acyl groups that improve the drug-like properties of the merulin A core, resulted in the development of compound 12 with an IC50 of 60 nM against T. brucei, and a selectivity index greater than 300-fold against HeLa and immortalized glial cells. Significance We report the semi-synthetic optimization of the merulin class of endoperoxide natural products as development candidates against T. brucei. We have identified compounds with low nM antiparasitic activities and high selectivity indices against HeLa cells. These compounds can be produced economically in large quantities via a one step derivatization from the microbial fermentation broth isolate, making them encouraging lead candidates for further development.

    The development of diagnostic tests for tuberculosis (TB) in exotic species is constrained by host biology and the limited availability of suitable assay reagents. As such, we evaluated a gene expression assay (GEA) which is easily modified for novel species and allows for initial sample processing under field conditions. African buffaloes (Syncerus caffer) were categorized using the single comparative intradermal tuberculin test, and blood from test-positive and test-negative animals was incubated for 20 h in "Nil" tubes (containing saline) and "TB Antigen" tubes (containing Mycobacterium tuberculosis complex (MTC)-specific antigens) of a commercial human TB test, the QuantiFERON(®)-TB Gold (In-Tube) (QFT) assay. Blood samples were then stabilized in RNAlater(®) and transported to the laboratory for RNA extraction. A Custom TaqMan GEA was used to calculate the relative abundance of interferon-gamma (IFN-γ) mRNA in the TB Antigen tube compared to that in the Nil tube as a marker of immune activation in response to MTC antigen recognition. The GEA results from the two buffalo groups were compared and a cutoff value of 2.85 was calculated to differentiate between animals from these groups with a sensitivity of 80% (95% C.I.: 56-94%) and a specificity of 95% (95% C.I.: 75-100%). Further optimization of this assay could provide a highly useful tool for the diagnosis of MTC infection in exotic species.

    The emergence of Anopheles species resistant to insecticides widely used in vector control has the potential to impact directly on the control of malaria. This may have a particularly dramatic effect in Africa, where pyrethroids impregnated onto bed-nets are the dominant insecticides used for vector control. Because the same insecticides are used for crop pests, the extensive use and misuse of insecticides for agriculture has contributed to the resistance problem in some vectors. The potential for resistance to develop in African vectors has been apparent since the 1950s, but the scale of the problem has been poorly documented. A geographical information system-based decision support system for malaria control has recently been established in Africa and used operationally in Mozambique. The system incorporates climate data and disease transmission rates, but to date it has not incorporated spatial or temporal data on vector abundance or insecticide resistance. As a first step in incorporating this information, available published data on insecticide resistance in Africa has now been collated and incorporated into this decision support system. Data also are incorporated onto the openly available Mapping Malaria Risk in Africa (MARA) Web site (http://www.mara.org.za). New data, from a range of vector population-monitoring initiatives, can now be incorporated into this open access database to allow a spatial understanding of resistance distribution and its potential impact on disease transmission to benefit vector control programs.

  11. Tradeoffs between somatic and gonadal investments during development in the African clawed frog (Xenopus laevis).

    Tradeoffs between time to and size at metamorphosis occur in many organisms with complex life histories. The ability to accelerate metamorphosis can increase survival to the next life stage, but the resulting smaller size at metamorphosis is often associated with lower post-metamorphic survival or reduced fecundity of adults. Reduced fecundity is thought to be because of reduced energy reserves, longer time to maturity, or reduced capacity to carry eggs or compete for mates. This pattern could also be explained by a shift in allocation to somatic growth that further retards the growth or development of reproductive tissues. The main goal of this study was to determine if the relationship between growth and development of somatic and gonadal tissues depends on environmental conditions. We address this question through two experiments in which we quantify the development and growth of the body and gonads of Xenopus laevis reared in different resource environments. First, tadpoles were reared communally and development and growth were evaluated over time. Restricted food reduced somatic and gonadal growth rate, but did not affect the developmental rate of either tissue type. Second, tadpoles were reared individually and evaluated at metamorphosis. Restricted food reduced somatic development and growth, but only influenced size, and not developmental stage of testes at metamorphosis. This work demonstrates that environmental conditions influence tradeoffs between growth and development of somatic and gonadal tissues, apparently in a sex-specific manner. These tradeoffs may contribute to phenotypic correlations between small size and reduced fitness.

  12. Expression and Sequence Evolution of Aromatase cyp19a1 and Other Sexual Development Genes in East African Cichlid Fishes

    Sex determination mechanisms are highly variable across teleost fishes and sexual development is often plastic. Nevertheless, downstream factors establishing the two sexes are presumably conserved. Here, we study sequence evolution and gene expression of core genes of sexual development in a prime model system in evolutionary biology, the East African cichlid fishes. Using the available five cichlid genomes, we test for signs of positive selection in 28 genes including duplicates from the teleost whole-genome duplication, and examine the expression of these candidate genes in three cichlid species. We then focus on a particularly striking case, the A- and B-copies of the aromatase cyp19a1, and detect different evolutionary trajectories: cyp19a1A evolved under strong positive selection, whereas cyp19a1B remained conserved at the protein level, yet is subject to regulatory changes at its transcription start sites. Importantly, we find shifts in gene expression in both copies. Cyp19a1 is considered the most conserved ovary-factor in vertebrates, and in all teleosts investigated so far, cyp19a1A and cyp19a1B are expressed in ovaries and the brain, respectively. This is not the case in cichlids, where we find new expression patterns in two derived lineages: the A-copy gained a novel testis-function in the Ectodine lineage, whereas the B-copy is overexpressed in the testis of the speciest-richest cichlid group, the Haplochromini. This suggests that even key factors of sexual development, including the sex steroid pathway, are not conserved in fish, supporting the idea that flexibility in sexual determination and differentiation may be a driving force of speciation.

    This paper describes effects of drilling with water and synthetic-based drilling muds on benthic macro-invertebrates over 10 years at the Terra Nova offshore oil development. As such, the paper provides insight on the effects of relatively new synthetic-based drilling muds (SBMs), and makes an important contribution to our understanding of the long-term chronic effects of drilling on benthic communities. The Terra Nova Field is located approximately 350 km offshore on the Grand Banks of Newfoundland (Canada). Sediment and invertebrate samples were collected in 1997 (baseline) prior to drilling, and subsequently in 2000, 2001, 2002, 2004, 2006, 2008 and 2010. Approximately 50 stations were sampled in each year at distances of less than 1 to approximately 20 km from drill centres. Summary benthic invertebrate community measures examined were total abundance, biomass, richness, diversity and multivariate measures of community composition based on non-Metric Dimensional Scaling (nMDS). Decreases in abundance, biomass and richness were noted at one station located nearest (0.14 km) to a drill centre in some environmental effects monitoring (EEM) years. These decreases coincided with higher levels of tracers of drill muds in sediments (barium and >C10-C21 hydrocarbons). Abundances of selected individual taxa were also examined to help interpret responses when project-related effects on summary measures occurred. Enrichment effects on some tolerant taxa (e.g., the polychaete family Phyllodocidae and the bivalve family Tellinidae) and decreased abundances of sensitive taxa (e.g., the polychaete families Orbiniidae and Paraonidae) were detected to within approximately 1-2 km from discharge source. Lagged responses three to five years after drilling started were noted for Phyllodocidae and Tellinidae, suggesting chronic or indirect effects. Overall, results of benthic community analyses at Terra Nova indicate that effects on summary measures of community composition were

    Orewa, S. I.

    The study was carried out to investigate farmers reasons for intercropping their oil palm farms with food and other cash crops rather than the sole oil palm planting arrangement specified for participation in the World Bank Assistance Smallholder Oil Palm development project financed during the 1975-83 period. The study was conducted at the Ekuku-Agbor Tree Crop Unit Zone (to the East) and Mosogar Tree Crop Unit Zone (to the Southwest) of the old Bendel State of Nigeria. A total of 35 oil palm farmers were randomly selected from each zone for the study. The study tried to identify the size of oil palm cultivated, types of food and cash crops planted and the proportion consumed and sold and the sufficiency of labour for various farm activities. The study showed that the average oil palm farm size at Ekuku-Agbor zone was smaller (about 1.57 ha) and more fragmented while for Mosogar zone it was 2.28 ha. However a greater percentage (over 65%) of the farms at both locations were within 0.01-2.00 ha farm size range which could be said to be relatively small. The study revealed that among other factors the farmers desire to ensure adequate family food needs which equates to food security and some cash to meet regular family financial needs necessitated their intercropping of the oil palm farms. Others include the need to maximize the returns from the use of labour which they considered a major limiting factor in farm maintenance and to take advantage of the relative high unit price of cassava and its products that prevailed then by cultivating on any available land space including the palm plantations and thereby increasing their farm income.

    Infections by protozoan parasites, such as Plasmodium falciparum or Leishmania donovani, have a significant health, social and economic impact and threaten billions of people living in tropical and sub-tropical regions of developing countries worldwide. The increasing range of parasite strains resistant to frontline therapeutics makes the identification of novel drug targets and the development of corresponding inhibitors vital. Post-translational modifications (PTMs) are important modulators of biology and inhibition of protein lipidation has emerged as a promising therapeutic strategy for treatment of parasitic diseases. In this review we summarize the latest insights into protein lipidation in protozoan parasites. We discuss how recent chemical proteomic approaches have delivered the first global overviews of protein lipidation in these organisms, contributing to our understanding of the role of this PTM in critical metabolic and cellular functions. Additionally, we highlight the development of new small molecule inhibitors to target parasite acyl transferases.

    Toroyan, Tamitza; Reddy, Priscilla S

    In response to an increasing incidence in HIV prevalence among South Africa's youth, a group of interdisciplinary professionals have developed a series of photocomics to address issues around HIV/AIDS communication and sexually transmitted diseases. This article examines the theory behind the use of photocomics in health, and the way the stories work to influence behavior. Results from evaluation of the comics support their use as tools with which to increase information and knowledge while role modeling desirable behavior. Lastly, the article describes the participatory process by which youth were involved in the process of developing and producing the comics. This method of developing culturally relevant and appealing health media is recommended for use in future health promotion strategies that seek to transcend a narrower approach of provision of health information and work to address the social factors that influence youth's decision making.

  17. Ontogenetic Development of Weberian Ossicles and Hearing Abilities in the African Bullhead Catfish

    2011-01-01

    Background The Weberian apparatus of otophysine fishes facilitates sound transmission from the swimbladder to the inner ear to increase hearing sensitivity. It has been of great interest to biologists since the 19th century. No studies, however, are available on the development of the Weberian ossicles and its effect on the development of hearing in catfishes. Methodology/Principal Findings We investigated the development of the Weberian apparatus and auditory sensitivity in the catfish Lophiobagrus cyclurus. Specimens from 11.3 mm to 85.5 mm in standard length were studied. Morphology was assessed using sectioning, histology, and X-ray computed tomography, along with 3D reconstruction. Hearing thresholds were measured utilizing the auditory evoked potentials recording technique. Weberian ossicles and interossicular ligaments were fully developed in all stages investigated except in the smallest size group. In the smallest catfish, the intercalarium and the interossicular ligaments were still missing and the tripus was not yet fully developed. Smallest juveniles revealed lowest auditory sensitivity and were unable to detect frequencies higher than 2 or 3 kHz; sensitivity increased in larger specimens by up to 40 dB, and frequency detection up to 6 kHz. In the size groups capable of perceiving frequencies up to 6 kHz, larger individuals had better hearing abilities at low frequencies (0.05–2 kHz), whereas smaller individuals showed better hearing at the highest frequencies (4–6 kHz). Conclusions/Significance Our data indicate that the ability of otophysine fish to detect sounds at low levels and high frequencies largely depends on the development of the Weberian apparatus. A significant increase in auditory sensitivity was observed as soon as all Weberian ossicles and interossicular ligaments are present and the chain for transmitting sounds from the swimbladder to the inner ear is complete. This contrasts with findings in another otophysine, the zebrafish

    Developing countries are currently going through a transitional phase facing the new challenges of globalization and its potential negative impact. Research policy should highlight the need to mobilize resources for human resource development, networking, improved research culture, information sharing, and pragmatic use of research findings. Advancement in molecular genetics whether at the educational or research level should greatly progress in developing countries so as to improve diagnosis, treatment, understanding of disease risk factors, and prevention. Currently, there is a growing interest to genetic toxicology research, the use of different biomarkers, and genetic susceptibility testing, which can contribute effectively in risk assessment. Africa has unique environmental exposures and public health circumstances, which make it ideal for environmental mutagenicity and carcinogenicity research. There are exposures to chemical genotoxicants (e.g., automobile exhaust, pesticides, metals, and cytotoxic drugs) and to lifestyle factors (e.g., consumption of tobacco products) that have been linked to the expression of biological effects and to increased risk for cancer. Infections can be associated with cancer development when the environmental factors interact with the infection and lead to the enhancement of the carcinogenic process. The high prevalence of viral pathogens and the improper use of pesticides may endanger biological functions beyond those for which they originally manufactured. Biomarkers are used to detect the effects of pesticides before adverse clinical health occurs. The scientific community plays a crucial role in understanding the environmental causes of human health problems and through its collaboration with communities, industries, and government agencies can help in resolving health problems.

Internationally, organizations such as UNESCO, the Group on Earth Observations (GEO), and the World Climate Research Programme (WCRP) have recognized the need for drought monitoring, especially for the developing world where drought has had devastating impacts on local populations through food insecurity and famine. Having the capacity to monitor droughts in real-time, and to provide drought forecasts with sufficient warning will help developing countries and international programs move from the management of drought crises to the management of drought risk. While observation-based assessments, such as those produced by the US Drought Monitor, are effective for monitoring in countries with extensive observation networks (of precipitation in particular), their utility is lessened in areas (e.g., Africa) where observing networks are sparse. For countries with sparse networks and weak reporting systems, remote sensing observations can provide the real-time data for the monitoring of drought. More importantly, these datasets are now available for at least a decade, which allows for the construction of a climatology against which current conditions can be compared. In this presentation we discuss the development of our multi-lingual experimental African Drought Monitor (ADM) (see http://hydrology.princeton.edu/~nchaney/ADM_ML). At the request of UNESCO, the ADM system has been installed at AGRHYMET, a regional climate and agricultural center in Niamey, Niger and at the ICPAC climate center in Nairobi, Kenya. The ADM system leverages off our U.S. drought monitoring and forecasting system (http://hydrology.princeton.edu/forecasting) that uses the NLDAS data to force the VIC land surface model (LSM) at 1/8th degree spatial resolution for the estimation of our soil moisture drought index (Sheffield et al., 2004).

    Currently, public health practitioners are analyzing the role that caregivers play in childhood obesity efforts. Assessing African American caregiver's perceptions of childhood obesity in rural communities is an important prevention effort. This article's objective is to describe the development and psychometric testing of a survey tool to assess childhood obesity perceptions among African American caregivers in a rural setting, which can be used for obesity prevention program development or evaluation. The Childhood Obesity Perceptions (COP) survey was developed to reflect the multidimensional nature of childhood obesity including risk factors, health complications, weight status, built environment, and obesity prevention strategies. A 97-item survey was pretested and piloted with the priority population. After pretesting and piloting, the survey was reduced to 59-items and administered to 135 African American caregivers. An exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) was conducted to test how well the survey items represented the number of Social Cognitive Theory constructs. Twenty items were removed from the original 59-item survey and acceptable internal consistency of the six factors (α=0.70-0.85) was documented for all scales in the final COP instrument. CFA resulted in a less than adequate fit; however, a multivariate Lagrange multiplier test identified modifications to improve the model fit. The COP survey represents a promising approach as a potentially comprehensive assessment for implementation or evaluation of childhood obesity programs.

    Physics, which is widely touted as the most fundamental of the sciences, underpins the progress in all other branches of science and has a wide range of applications in economic development, including in health, energy research, food security, communication technology and climate change. The African Union (AU) Commission articulates the continental vision of its Member States and its programs are designed to directly contribute to its social and economic development and integration efforts. In the area of science and technology the Department has developed Africa's Science and Technology Consolidated Plan of Action as a strategic policy document through the AU system of conference of ministers responsible for science to guide the continent on common priority programs. The programs in this plan of action that have been transformed into bankable projects under the Book of ``lighthouse projects Phase 1'', adequately respond to Africa's challenges and development needs using science. They can be summarized into three main themes: a pan-African university (PAU) initiative (to combine higher education and scientific research as a network of differentiated PAU in each of the five African regions), African research grants (to strengthen the research capacity of the African institutions and upgrading infrastructures, consolidating their accumulated asset of scientific knowledge), popularization of science and technology and promotion of public participation (to build public understanding and raising awareness on science and technology as a driving agent for social and economic progress for Africa and its integration process) and a science and technology institutional capacity building program). This talk will review these programs as well as the vision of the African Development Bank role in it. )

    GHG (greenhouse gas) emission factors for waste management are increasingly used, but such factors are very scarce for developing countries. This paper shows how such factors have been developed for the recycling of glass, metals (Al and Fe), plastics and paper from municipal solid waste, as well as for the composting of garden refuse in South Africa. The emission factors developed for the different recyclables in the country show savings varying from -290kg CO2 e (glass) to -19111kg CO2 e (metals - Al) per tonne of recyclable. They also show that there is variability, with energy intensive materials like metals having higher GHG savings in South Africa as compared to other countries. This underlines the interrelation of the waste management system of a country/region with other systems, in particular with energy generation, which in South Africa, is heavily reliant on coal. This study also shows that composting of garden waste is a net GHG emitter, releasing 172 and 186kg CO2 e per tonne of wet garden waste for aerated dome composting and turned windrow composting, respectively. The paper concludes that these emission factors are facilitating GHG emissions modelling for waste management in South Africa and enabling local municipalities to identify best practice in this regard.

  18. Laboratory Diagnosis of Tick-Borne African Relapsing Fevers: Latest Developments

    PubMed Central

    Fotso Fotso, Aurélien; Drancourt, Michel

    2015-01-01

    In Africa, relapsing fevers caused by ectoparasite-borne Borrelia species are transmitted by ticks, with the exception of Borrelia recurrentis, which is a louse-borne spirochete. These tropical diseases are responsible for mild to deadly spirochetemia. Cultured Borrelia crocidurae, Borrelia duttonii, and Borrelia hispanica circulate alongside at least six species that have not yet been cultured in vectors. Direct diagnosis is hindered by the use of non-specific laboratory tools. Indeed, microscopic observation of Borrelia spirochaeta in smears of peripheral blood taken from febrile patients lacks sensitivity and specificity. Although best visualized using dark-field microscopy, the organisms can also be detected using Wright–Giemsa or acridine orange stains. PCR-based detection of specific sequences in total DNA extracted from a specimen can be used to discriminate different relapsing fever Borreliae. In our laboratory, we developed a multiplex real-time PCR assay for the specific detection of B. duttonii/recurrentis and B. crocidurae: multispacer sequence typing accurately identified cultured relapsing fever borreliae and revealed diversity among them. Other molecular typing techniques, such as multilocus sequence analysis of tick-borne relapsing fever borreliae, showed the potential risk of human infection in Africa. Recent efforts to culture and sequence relapsing fever borreliae have provided new information for reassessment of the diversity of these bacteria. Recently, matrix-assisted laser desorption/ionization time-of-flight mass spectrometry has been reported as a means of identifying cultured borreliae and of identifying both vectors and vectorized pathogens such as detecting relapsing fever borreliae directly in ticks. The lack of a rapid diagnosis test restricts the management of such diseases. We produced monoclonal antibodies against B. crocidurae in order to develop cheap assays for the rapid detection of relapsing fever borreliae. In this paper, we

    Objectives: To estimate age at attaining Tanner stages in Ugandan/Zimbabwean HIV-infected children initiating antiretroviral therapy (ART) in older childhood and investigate predictors of delayed puberty, particularly age at ART initiation. Design: Observational analysis within a randomized trial. Methods: Tanner staging was assessed every 24 weeks from 10 years of age, menarche every 12 weeks and height every 4–6 weeks. Age at attaining different Tanner stages was estimated using normal interval regression, considering predictors using multivariable regression. Growth was estimated using multilevel models with child-specific intercepts and trajectories. Results: Median age at ART initiation was 9.4 years (inter-quartile range 7.8, 11.3) (n = 582). At the first assessment, the majority (80.2%) were in Tanner stage 1; median follow-up with staging was 2.8 years. There was a strong delaying effect of older age at ART initiation on age at attaining all Tanner stages (P < 0.05) and menarche (P = 0.02); in boys the delaying effect generally weakened with older age. There were additional significant delays associated with greater impairments in pre-ART height-for-age Z-score (P < 0.05) in both sexes and pre-ART BMI-for-age in girls (P < 0.05). There was no evidence that pre-ART immuno-suppression independently delayed puberty or menarche. However, older children/adolescents had significant growth spurts in intermediate Tanner stages, and were still significantly increasing their height when in Tanner stage 5 (P < 0.01). Conclusion: Delaying ART initiation until older childhood substantially delays pubertal development and menarche, independently of immuno-suppression. This highlights that factors other than CD4+, such as pubertal development, need consideration when making decisions about timing of ART initiation in older children. PMID:25710288

  20. Development and validation of risk profiles of West African rural communities facing multiple natural hazards.

    West Africa has been described as a hotspot of climate change. The reliance on rain-fed agriculture by over 65% of the population means that vulnerability to climatic hazards such as droughts, rainstorms and floods will continue. Yet, the vulnerability and risk levels faced by different rural social-ecological systems (SES) affected by multiple hazards are poorly understood. To fill this gap, this study quantifies risk and vulnerability of rural communities to drought and floods. Risk is assessed using an indicator-based approach. A stepwise methodology is followed that combines participatory approaches with statistical, remote sensing and Geographic Information System techniques to develop community level vulnerability indices in three watersheds (Dano, Burkina Faso; Dassari, Benin; Vea, Ghana). The results show varying levels of risk profiles across the three watersheds. Statistically significant high levels of mean risk in the Dano area of Burkina Faso are found whilst communities in the Dassari area of Benin show low mean risk. The high risk in the Dano area results from, among other factors, underlying high exposure to droughts and rainstorms, longer dry season duration, low caloric intake per capita, and poor local institutions. The study introduces the concept of community impact score (CIS) to validate the indicator-based risk and vulnerability modelling. The CIS measures the cumulative impact of the occurrence of multiple hazards over five years. 65.3% of the variance in observed impact of hazards/CIS was explained by the risk models and communities with high simulated disaster risk generally follow areas with high observed disaster impacts. Results from this study will help disaster managers to better understand disaster risk and develop appropriate, inclusive and well integrated mitigation and adaptation plans at the local level. It fulfills the increasing need to balance global/regional assessments with community level assessments where major decisions

    Purpose To identify single nucleotide polymorphisms (SNPs) associated with erectile dysfunction (ED) among African American prostate cancer patients treated with external beam radiation therapy (EBRT). Methods and Materials A cohort of African American prostate cancer patients treated with EBRT was followed for development of ED using the five-item Sexual Health Inventory for Men (SHIM) questionnaire. Final analysis included 27 cases (post-treatment SHIM score ≤ 7) and 52 controls (post-treatment SHIM score ≥ 16). A genome-wide association study was performed using ∼909,000 SNPs genotyped on Affymetrix 6.0 arrays. Results We identified SNP rs2268363, located in the follicle stimulating hormone receptor (FSHR) gene, as significantly associated with ED after correcting for multiple comparisons (unadjusted p-value = 5.46×10−8; Bonferroni p-value = 0.028). We identified four additional SNPs that tended toward significant association with unadjusted p-value < 10−06. Inference of population substructure revealed that cases had a higher proportion of African ancestry compared to controls (77% compared to 60%, p=0.005). A multivariate logistic regression model that incorporated estimated ancestry and four of the top-ranked SNPs was a more accurate classifier of ED than a model that included only clinical variables. Conclusions To the best of our knowledge, this is the first genome wide association study to identify SNPs associated with adverse effects resulting from radiotherapy. It is important to note that the SNP that proved significantly associated with ED is located within a gene whose encoded product plays a role in male gonad development and function. Another key finding of this project is that the four SNPs most strongly associated with ED were specific to people of African ancestry and would therefore not have been identified had a cohort of European ancestry been screened. This study demonstrates the feasibility of a genome-wide approach to investigate

    African pit latrines produce prodigious numbers of the latrine fly, Chrysomya putoria, a putative vector of diarrhoeal pathogens. We set out to develop a simple, low-cost odour-baited trap for collecting C. putoria in the field. A series of field experiments was carried out in The Gambia to assess the catching-efficiency of different trap designs. The basic trap was a transparent 3L polypropylene box baited with 50 g of fish, with a white opaque lid with circular entrance holes. We tested variations of the number, diameter, position and shape of the entrance holes, the height of the trap above ground, degree of transparency of the box, its shape, volume, colour, and the attractiveness of gridded surfaces on or under the trap. Traps were rotated between positions on different sampling occasions using a Latin Square design. The optimal trapping features were incorporated into a final trap that was tested against commercially available traps. Features of the trap that increased the number of flies caught included: larger entrance holes (compared with smaller ones, p<0.001), using conical collars inside the holes (compared with without collars, p = 0.01), entrance holes on the top of the trap (compared with the side or bottom, p<0.001), traps placed on the ground (compared with above ground, p<0.001), the box having transparent sides (compared with being opaque, p<0.001), and with no wire grids nearby (compared with those with grids, p = 0.03). This trap collected similar numbers of C. putoria to other common traps for blow flies. The optimum trap design was a transparent box, with a white plastic lid on top, perforated with 10 conical entrance holes, placed on the ground. Our simple trap provides a cheap, low-maintenance and effective method of sampling C. putoria in the field.

    Background Addressing diet-related non-communicable diseases (NCDs) will require a multisectoral policy approach that includes the food supply and trade, but implementing effective policies has proved challenging. The Southern African Development Community (SADC) has experienced significant trade and economic liberalization over the past decade; at the same time, the nutrition transition has progressed rapidly in the region. This analysis considers the relationship between regional trade liberalization and changes in the food environment associated with poor diets and NCDs, with the aim of identifying feasible and proactive policy responses to support healthy diets. Design Changes in trade and investment policy for the SADC were documented and compared with time-series graphs of import data for soft drinks and snack foods to assess changes in imports and source country in relation to trade and investment liberalization. Our analysis focuses on regional trade flows. Results Diets and the burden of disease in the SADC have changed since the 1990s in parallel with trade and investment liberalization. Imports of soft drinks increased by 76% into SADC countries between 1995 and 2010, and processed snack foods by 83%. South Africa acts as a regional trade and investment hub; it is the major source of imports and investment related to these products into other SADC countries. At the same time, imports of processed foods and soft drinks from outside the region - largely from Asia and the Middle East - are increasing at a dramatic rate with soft drink imports growing by almost 1,200% and processed snack foods by 750%. Conclusions There is significant intra-regional trade in products associated with the nutrition transition; however, growing extra-regional trade means that countries face new pressures in implementing strong policies to prevent the increasing burden of diet-related NCDs. Implementation of a regional nutrition policy framework could complement the SADC

    Objective To explore ways of controlling Chrysomya putoria, the African latrine fly, in pit latrines. As pit latrines are a major source of these flies, eliminating these important breeding sites is likely to reduce village fly populations, and may reduce the spread of diarrhoeal pathogens. Methods We treated 24 latrines in a Gambian village: six each with (i) pyriproxyfen, an insect juvenile hormone mimic formulated as Sumilarv® 0.5G, a 0.5% pyriproxyfen granule, (ii) expanded polystyrene beads (EPB), (iii) local soap or (iv) no treatment as controls. Flies were collected using exit traps placed over the drop holes, weekly for five weeks. In a separate study, we tested whether latrines also function as efficient flytraps using the faecal odours as attractants. We constructed six pit latrines each with a built-in flytrap and tested their catching efficiency compared to six fish-baited box traps positioned 10 m from the latrine. Focus group discussions conducted afterwards assessed the acceptability of the flytrap latrines. Results Numbers of emerging C. putoria were reduced by 96.0% (95% CIs: 94.5–97.2%) 4–5 weeks after treatment with pyriproxyfen; by 64.2% (95% CIs: 51.8–73.5%) after treatment with local soap; by 41.3% (95% CIs = 24.0–54.7%) after treatment with EPB 3–5 weeks after treatment. Flytraps placed on latrines collected C. putoria and were deemed acceptable to local communities. Conclusions Sumilarv 0.5G shows promise as a chemical control agent, whilst odour-baited latrine traps may prove a useful method of non-chemical fly control. Both methods warrant further development to reduce fly production from pit latrines. A combination of interventions may prove effective for the control of latrine flies and the diseases they transmit. PMID:23198767

    Western conceptions of child development and the models of early education they engender predominantly shape services for young children in the first eight years of life all over Africa. This chapter brings a reconceptualist perspective to the critique of Kenya's continuing failure to ground early childhood programs and services in local cultural conceptions, developmental values, childrearing practices, and the practical day-to-day realities of children's learning through participation and apprenticeship in the contexts of family routines, community experiences, and economic survival activities. The chapter draws on work I have conducted in nomadic pastoralist communities in Kenya. That research reveals the disconcerting reality that (a) early childhood education programs privilege Western pedagogical practices over equally effective and locally more relevant ones, and (b) local communities are increasingly resentful of an educational system that alienates their children from their cultural roots in the name of modernization. Asserting the educational value of indigenous knowledge, I present a framework for integrating that knowledge and the naturalistic learning processes in local contexts into instructional programs in formal ECE settings.

    Research findings from various countries in West Africa clearly indicate that over 94 per cent of the adult population above 40 years of age suffer from periodontal disease in various degrees of severity. Those living in rural areas in West Africa, where dental health care services are not yet available, suffer more from this common disease. With progressive urbanization and changes in diet and eating habits, consumption of refined sugars is rising steeply (Table II) and dental caries has become a serious problem particularly in children from high socioeconomic homes. In Nigeria, DMF of 4-3 in the female and 3-9 in the male has been reported. There is general paucity of all cadres of dental manpower in all areas in West Africa. Dentist: population ratios range from 1 : 111,000 in Senegal to 1 : 1,935,000 in Tchad Republic (Table I). In Senegal, Ghana and Nigeria, Dental schools have been established and attempts are being made to meet the pressing need for dental manpower by the expansion of existing treatment centres and training institutions and the establishment of new ones (Table IV & V). Emphasis is laid on preventive dental health care programmes and the formal training of dental auxiliary personnel: Dental Therapists, Dental Hygienists, Dental Technicians and Dental Surgery Assistants, is taking place in Nigeria and Senegal. Dental Nurses/Therapists and Dental Hygienists if adequately trained in sufficient numbers can play an all-important role in the delivery of dental care and the execution of preventive programmes in the vast rural areas in the developing countries of West Africa with a population of over 122 million people.

    Cadmium is well known for its toxicity to the animal body. However, its effect on pregnancy and the development of young animals is still not well understood. This study examined such effects, using bank voles captured from the wild to make the results closer to those which could be expected in the natural environment. One group of animals was fed 7 microg g(-1) cadmium in the food, a second 35 microg g(-1), and a third no cadmium, as a control. The concentrations of cadmium in the whole bodies of young bank voles were determined on the 3rd, 5th, or 10th day of life. The cadmium level in the bodies of animals exposed to 35 microg g(-1) of cadmium was significantly higher than in those from either the control group or the group receiving 7 microg g(-1) of cadmium, which did not differ from each other. The cadmium level did not change with animal age in any of the study groups. Concentrations of Zn, Cu, and Fe were also determined in the whole body of young animals, as cadmium is known to disturb the metabolism of these essential metals through antagonistic activity. Both Cu and Fe levels were negatively correlated with cadmium concentrations, while a positive correlation was found between zinc and cadmium in the young animal bodies. Also found was higher offspring mortality in the group receiving 35 microg g(-1) of cadmium in food. There was no difference in young animal body weight between the study groups.

    Iodine is important for normal growth and psychomotor development. While infants below 6 months of age receive iodine from breast milk or fortified infant formula, the introduction of complementary foods poses a serious risk for deteriorating iodine status. This cross-sectional analysis assessed the iodine status of six-month-old South African infants and explored its associations with feeding practices and psychomotor milestone development. Iodine concentrations were measured in infant (n = 386) and maternal (n = 371) urine (urinary iodine concentration [UIC]), and in breast milk (n = 257 [breast milk iodine concentrations]). Feeding practices and psychomotor milestone development were assessed in all infants. The median (25th-75th percentile) UIC in infants was 345 (213-596) μg/L and was significantly lower in stunted (302 [195-504] μg/L) than non-stunted (366 [225-641] μg/L) infants. Only 6.7% of infants were deficient. Maternal UIC (128 [81-216] μg/L; rs  = 0.218, p < 0.001) and breast milk iodine concentrations (170 [110-270] μg/kg; rs  = 0.447, p < 0.0001) were associated with infant UIC. Most infants (72%) were breastfed and tended to have higher UIC than non-breastfed infants (p = 0.074). Almost all infants (95%) consumed semi-solid or solid foods, with commercial infant cereals (60%) and jarred infant foods (20%) being the most common solid foods first introduced. Infants who reported to consume commercial infant cereals ≥4 days weekly had significantly higher UIC (372 [225-637] μg/L) than those reported to consume commercial infant cereals seldom or never (308 [200-517] μg/L; p = 0.023). No associations between infant UIC and psychomotor developmental scores were observed. Our results suggest that iodine intake in the studied six-month-old infants was adequate. Iodine in breast milk and commercial infant cereals potentially contributed to this adequate intake.

    1998-01-01

    Electronic verification of ABO compatibility (computer crossmatching) has been accepted as the crossmatching procedure for patients without clinically significant alloantibodies. Computer crossmatching offers several advantages over the immediate spin crossmatch and enables the setting up of a self service blood banking system. Self service blood banking saves manpower, improves crossmatch/transfusion(C/T) ratio and makes the maximum surgical blood ordering schedule (MSBOS) redundant. Blood banking service can also be provided at satellite hospitals without stationing blood banking staff there. We have also developed a novel self service system that does not require expensive computer hardware and networking.

    African-American adolescent girls are at disproportionate risk for HIV infection. Although numerous evidence-based risk-reduction interventions exist, dissemination and implementation resources remain limited, and prevention services remain notably inaccessible to the very populations at highest risk for HIV infection. Internet delivery of HIV risk-reduction programming has promise as a mechanism for extending the reach of existing prevention efforts and overcoming barriers associated with traditional service delivery. This article: (1) details the development process for the creation of SiHLEWeb, a web-adapted version of an evidence-based, culturally-informed HIV prevention program traditionally delivered to female African-American adolescents via an in-person group format; and (2) presents findings from quantitative and qualitative usability testing conducted among 18 African-American girls (13–18). Results suggest that users found the website improved knowledge and learning, was helpful, efficient to use, and generally attractive. Users reported some concerns about website navigation. Implications for internet delivery of health prevention programming are discussed. PMID:25167865

    Background African American youth are at increased risk for poor diabetes management. Parenting behaviors such as parental monitoring are significant predictors of youth diabetes management and metabolic control, but no intervention has targeted parental monitoring of daily diabetes care. Objective The purpose of the present study was to develop and pilot test a three-session computer-delivered intervention to enhance parental motivation to monitor African American pre-adolescents’ diabetes management. Methods The 3 Ms (Medication, Meter, and Meals) intervention was based on the Information-Motivation-Behavioral Skills (IMB) model of health behavior change and Motivational Interviewing approaches. Five caregivers of African American youth aged 10-13 years diagnosed with type 1 diabetes for a minimum of one year (ie, the target population) reviewed the intervention and provided feedback via semi-structured interviews. Interviews were transcribed and analyzed using thematic analysis. Results Caregivers’ responses to interview questions suggest that The 3 Ms was helpful (minimum rating was 8 out of 10) and they would recommend the program to another parent of a child with diabetes (minimum rating was 9 out of 10). Three of five reported that The 3 Ms program increased the likelihood that they would talk to their child about diabetes. Thematic analysis suggested two primary themes: caregivers found the intervention to be a useful reminder of the importance of supervising their child’s diabetes care and that it evoked a feeling of shared experience with other parents. Conclusions The 3 Ms computer-delivered intervention for increasing parental monitoring of African-American youth with type 1 diabetes was well-received and highly rated by a small sample of representative caregivers.

    Dredged and straightened channels in eastern Nebraska have experienced degradation leading to channel widening by bank failure. Degradation has progressed headward and affected the drainage systems upstream from the modified reaches. This report describes a study that was undertaken to analyze bank stability at selected sites in eastern Nebraska and develop a simplified method for estimating the stability of banks at future study sites. Bank cross sections along straight reaches of channel and geotechnical data were collected at approximately 150 sites in 26 counties of eastern Nebraska. The sites were categorized into three groups based on mapped soil permeability. With increasing permeability of the soil groups, the median cohesion values decreased and the median friction angles increased. Three analytical methods were used to determine if banks were stable (should not fail even when saturated), at risk (should not fail unless saturated), or unstable (should have already failed). The Culmann and Agricultural Research Service methods were based on the Coulomb equation and planar failure; an indirect method was developed that was based on Bishop's simplified method of slices and rotational failure. The maximum angle from horizontal at which the bank would be stable for the given soil and bank height conditions also was computed with the indirect method. Because of few soil shear-strength data, all analyses were based on the assumption of homogeneous banks, which was later shown to be atypical, at least for some banks. Using the Culmann method and assuming no soil tension cracks, 67 percent of all 908 bank sections were identified as stable, 32 percent were at risk, and 1 percent were unstable; when tension cracks were assumed, the results changed to 58 percent stable, 40 percent at risk, and 1 percent unstable. Using the Agricultural Research Service method, 67 percent of all bank sections were identified as stable and 33 percent were at risk. Using the indirect

    In the last decade the technical advances in high throughput techniques to analyze DNA, RNA and proteins have had a potential major impact on prevention, diagnosis, prognosis and treatment of many human diseases. Key pieces in this process, mainly thinking about the future, are tumour banks and tumour bank networks. To face these challenges, diverse suitable models and designs can be developed. The current article presents the development of a nationwide design of tumour banks in Spain based on a network of networks, specially focusing on its harmonization efforts mainly regarding technical procedures, ethical requirements, unified quality control policy and unique sample identification. We also describe our most important goals for the next years. This model does not correspond to a central tumour bank, but to a cooperative and coordinated network of national and regional networks. Independently from the network in which it is included, sample collections reside in their original institution, where it can be used for further clinical diagnosis, teaching and research activities of each independent hospital. The herein described 'network of networks' functional model could be useful for other countries and/or international tumour bank activities.

  8. Glacial interglacial cycles and development of the Afroalpine ecosystem on East African Mountains II. Origins and development of the biotic component

    NASA Astrophysics Data System (ADS)

    Harmsen, R.; Spence, J. R.; Mahaney, W. C.

    The development of the Afroalpine ecosystem as found on a number of isolated mountains in East Africa has a physical component and a biological component which is to a large degree dependent on the physical environment. The origins of the Afroalpine biota are predominantly African-tropical or Palearctic with smaller contributions from South Africa and other more distant sources. Once the ecosystem was established, dispersal from one mountain to others became a main source of increasing complexity. Ecological succession and evolutionary development from simple random assemblages of early invading species on unmodified substrates to complex interactive communities forming a closely integrated biosphere would have been the next stage in the development of the Afroalpine ecosystem. However, glacial interglacial cycles throughout the Pleistocene may have seriously curtailed this process. Detailed on early succession on Neoglacial tills on Mount Kenya supply a reasonable model for the larger scale recolonization of the upper reaches of the mountain following each glacial, and palynological evidence supplies a fairly accurate picture of the lower altitude glacial Afroalpine communities. Yet, our knowledge of the structure of the Afroalpine ecosystem during past glacials and interglacials is far too sketchy to be able to say how severe the effects of the climatic oscillations were on the development and maintenance of the Afroalpine ecosystem. Current conditions indicate a long history (c 2-3 mil yrs) of adaptation to above tree-line conditions for some organisms, but the entire ecosystem is still very young and will probably never be able to reach a successional or evolutionary equilibrium in the unstable climatic conditions of the Afroalpine environment.

    Bumblefoot (pododermatitis), often described as the most significant environmental disease of captive penguins, is commonly due to excessive pressure or trauma on the plantar surface of the avian foot, resulting in inflammation or necrosis and causing severe swelling, abrasions, or cracks in the skin. Although not formally evaluated in penguins, contributing factors for bumblefoot are thought to be similar to those initiating the condition in raptors and poultry. These factors include substrate, body weight, and lack of exercise. The primary purpose of this retrospective study was to evaluate variables potentially contributing to the development and duration of plantar lesions in aquarium-maintained African penguins (Spheniscus demersus), including sex, weight, age, season, exhibit activity, and territory substrate. Results indicate that males develop significantly more plantar lesions than females. Penguins weighing between 3.51 and 4.0 kg develop plantar lesions significantly more often than penguins weighing between 2.5 and 3.5 kg, and because male African penguins ordinarily weigh significantly more than females, weight is likely a contributing factor in the development of lesions in males compared with females. Significantly more plantar lesions were observed in penguins standing for greater than 50% of their time on exhibit than swimming. Penguins occupying smooth concrete territories developed more plantar lesions compared with penguins occupying grate territories. Recommendations for minimizing bumblefoot in African penguins include training penguins for monthly foot examinations for early detection of plantar lesions predisposing for the disease, encouraging swimming activity, and replacing smooth surfaces on exhibit with surfaces providing variable degrees of pressure and texture on the feet.

    The economic effects of Bahrain's schemes for licensing offshore banking units (OBUs) were the immediate response of major international banks and the financial services the banking center has rendered by improving regional money and exchange markets at a time when a Middle East link was needed to service the increasing demand for oil-wealth banking services. Bahrain's leadership also created a favorable climate. Aggressive competition from banks in Kuwait and Saudi Arabia have caused some friction, but informal supervision by the Bahrain Monetary Agency (BMA) should be able to avoid serious difficulty. Bahrain's success required a banking infrastructure, a free-enterprise system, a willingness to maintain banking standards, a country small enough to benefit directly from OBU income, and a gap in nearby competing centers. 39 references, 1 figure, 5 tables.

    The World Bank Group regards excessive population growth as the single greatest obstacle to economic and social advance in the underdeveloped world. Since 1969 the Bank and the International Development Agency have provided countries with technical assistance through education, fact-finding, and analysis and given 65.7 million dollars for population projects. These projects, in India, Indonesia, Iran, Jamaica, and Malaysia provide training centers, population education, research, and evaluation as well as actual construction of clinics and mobile units. Because population planning touches sensitive areas of religion, caste, race, morality, and politics, the involved nation's political commitment to plan population growth is critical to the success of any program.

  19. African American Advanced Placement chemistry students and their developing study habits: A phenomenologically-based interpretive study

    Rasmussen, Natalie D.

    The academic achievement gap between African American and White students has gained much attention in recent years. Much has been written about the causes of and reasons for this problem ranging from the vestigial effects of slavery to poor parenting. Much less has been written or understood about its solution. While it is impossible for educators to change the pasts of their African American students, it is possible to effect change for the few minutes in which they are in direct contact with them each day. If African American science students are taught effective study skills and habits, then perhaps they might have the tools to close the achievement gap themselves. The participants in this phenomenologically based interpretive study were five African American Advanced Placement Chemistry students from an inner-city high school. Three in-depth interviews were conducted with each of the participants during the beginning, middle and end of a semester. The purpose of the interviews was to locate the students in terms of their thought processes, experiences and perceived barriers concerning the nature and practice of effective study and retention of chemistry content. The interviews were recorded and transcribed. The texts were then analyzed for common themes. Five common themes emerged from the interviews. These were: (1) Homework vs. Study: a distinction between homework---which students knew how to approach; and study---which they did not. (2) Student Effort: their changing perception of adequate and effective study practices while in a rigorous course. (3) Teacher Rigor: they perceived high expectations and challenging work as a sign of respect from their teachers. (4) Parental Involvement: students' admission that they desired more input from parents regarding their academic performance. (5) Racial Considerations: their need to disprove negative stereotypes and their personal observations regarding racial differences in studying. A discussion of the themes and

    A nested PCR assay, with an internal control, was developed to detect African swine fever virus (ASFV) DNA in Ornithodoros erraticus. The assay revealed a better analytical sensitivity than virus isolation and the OIE PCR protocol. All ticks collected from the field, which were positive by virus isolation, were also positive by PCR. Viral DNA was detected in a further 19 out of 60 ticks from which no virus was isolated. Our results show that this assay is reliable and can easily be used to screen large tick populations collected in the field for the presence of ASFV.
