    Coburn, Carolyn; Restivo, Michael; Shandra, John M

    2015-05-01

    We conduct a cross-national analysis to test the hypothesis that African Development Bank (AfDB) structural adjustment lending adversely impacts maternal mortality in Sub-Saharan Africa. We analyze data for thirty-five Sub-Saharan African nations with up to four time points (1990, 1995, 2000, and 2005) with generalized least squares random effects regression models and modified two-step Heckman models that correct for potential endogeneity regarding whether or not a Sub-Saharan African nations receives an AfDB structural adjustment loan. We find support for our hypothesis that indicates that Sub-Saharan African nations that receive an AfDB structural adjustment loan tend to have higher levels of maternal mortality than Sub-Saharan African nations that do not receive such a loan. This finding remains stable even when controlling for endogeneity. We conclude by talking about the theoretical and methodological implications along with possible directions for future research.

    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.

  3. Astronomy for African development

    2011-06-01

    In recent years there have been a number of efforts across Africa to develop the field of astronomy as well as to reap benefit from astronomy for African people. This presentation will discuss the case of the SALT (Southern African Large Telescope) Collateral Benefits Programme (SCBP) which was set up to ensure societal benefit from astronomy. With African society as the target, the SCBP has embarked on various projects from school level education to public understanding of science to socio-economic development, the latter mainly being felt in the rural communities surrounding the South African Astronomical Observatory (home to SALT). A development plan for ``Astronomy in Africa'' will also be discussed. This plan has been drawn up with input from all over Africa and themed ``Astronomy for Education''. The Africa case stands as a good example for the IYA cornerstone project ``Developing Astronomy Globally'' which focuses on developing regions.

  4. Development of tissue bank

    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.

    PubMed

    Madzimbamuto, Farai Daniel

    2012-03-01

    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. PMID:22380900

  14. 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.

    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.

  1. Body temperatures of free-living African penguins (Spheniscus demersus) and bank cormorants (Phalacrocorax neglectus).

    PubMed

    Wilson, R P; Grémillet, D

    1996-10-01

    Two free-living seabirds (the African penguin Spheniscus demersus and the bank cormorant Phalacrocorax neglectus) were equipped with stomach temperature-loggers to study body temperature changes during foraging. Body temperature in these endotherms was environmentally and activity-dependent and varied in the case of the cormorant by over 5 degrees C. Considerations of heat flux show that such flexibility confers considerable energetic advantages: by allowing body temperature to drop when the heat loss to the environment is high, such as in water, birds may save the energy that would normally be necessary to compensate for this drop. It appears that, in cormorants, low body temperature resulting from extended time in water can subsequently be elevated using solar energy when birds return to land in a manner similar to that of ectotherms. In the better-insulated penguins, muscle-generated heat during swimming is used to re-elevate low body temperature. Continued swimming eventually causes body temperature to rise above normal resting levels so that metabolic rate could theoretically be dramatically reduced immediately post-exercise when the temperature drops to some critical level before any increase in metabolism is necessary to correct it.

  2. 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

    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.

  5. Methodology for Developing and Evaluating the PROMIS® Smoking Item Banks

    PubMed Central

    Cai, Li; Stucky, Brian D.; Tucker, Joan S.; Shadel, William G.; Edelen, Maria Orlando

    2014-01-01

    Introduction: This article describes the procedures used in the PROMIS® Smoking Initiative for the development and evaluation of item banks, short forms (SFs), and computerized adaptive tests (CATs) for the assessment of 6 constructs related to cigarette smoking: nicotine dependence, coping expectancies, emotional and sensory expectancies, health expectancies, psychosocial expectancies, and social motivations for smoking. Methods: Analyses were conducted using response data from a large national sample of smokers. Items related to each construct were subjected to extensive item factor analyses and evaluation of differential item functioning (DIF). Final item banks were calibrated, and SF assessments were developed for each construct. The performance of the SFs and the potential use of the item banks for CAT administration were examined through simulation study. Results: Item selection based on dimensionality assessment and DIF analyses produced item banks that were essentially unidimensional in structure and free of bias. Simulation studies demonstrated that the constructs could be accurately measured with a relatively small number of carefully selected items, either through fixed SFs or CAT-based assessment. Illustrative results are presented, and subsequent articles provide detailed discussion of each item bank in turn. Conclusions: The development of the PROMIS smoking item banks provides researchers with new tools for measuring smoking-related constructs. The use of the calibrated item banks and suggested SF assessments will enhance the quality of score estimates, thus advancing smoking research. Moreover, the methods used in the current study, including innovative approaches to item selection and SF construction, may have general relevance to item bank development and evaluation.

  6. 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.

    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

    Introduction: Smoking behavior is influenced by social motivations such as the expected social benefits of smoking and the social cues that induce craving. This paper describes development of the PROMIS® Social Motivations for Smoking item banks, which will serve to standardize assessment of these social motivations among daily and nondaily smokers. Methods: Daily (N = 4,201) and nondaily (N =1,183) smokers completed an online survey. Item factor analyses, item response theory analyses, and differential item functioning analyses were conducted to identify a unidimensional set of items for each group. Short forms (SFs) and computer adaptive tests (CATs) were evaluated as tools for more efficiently assessing this construct. Results: A total of 15 items were included in the item banks (9 items common to daily and nondaily smokers, 3 unique to daily, 3 unique to nondaily). Scores based on full item banks are highly reliable (reliability = 0.90–0.91). Additionally, the item banks are strongly unidimensional and perform similarly across gender, age, and race/ethnicity groups. A fixed SF for use with both daily and nondaily smokers consists of 4 items (reliability = 0.80). Results from simulated CATs showed that, on average, fewer than 5 items are needed to assess this construct with adequate precision using the item banks. Conclusions: A new set of items has been identified for assessing the social motivations for smoking in a reliable, standardized manner for daily and nondaily smokers. In addition to using the full item banks, efficient assessment can be achieved by using SFs, employing CATs, or selecting items tailored to specific research or clinical purposes. PMID:25118231

    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

    Introduction: Nicotine dependence is a core construct important for understanding cigarette smoking and smoking cessation behavior. This article describes analyses conducted to develop and evaluate item banks for assessing nicotine dependence among daily and nondaily smokers. 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 nicotine dependence items for daily and nondaily smokers. We also evaluated performance of short forms (SFs) and computer adaptive tests (CATs) to efficiently assess dependence. Results: A total of 32 items were included in the Nicotine Dependence item banks; 22 items are common across daily and nondaily smokers, 5 are unique to daily smokers, and 5 are unique to nondaily smokers. For both daily and nondaily smokers, the Nicotine Dependence item banks are strongly unidimensional, highly reliable (reliability = 0.97 and 0.97, respectively), and perform similarly across gender, age, and race/ethnicity groups. SFs common to daily and nondaily smokers consist of 8 and 4 items (reliability = 0.91 and 0.81, respectively). Results from simulated CATs showed that dependence can be assessed with very good precision for most respondents using fewer than 6 items adaptively selected from the item banks. Conclusions: Nicotine dependence on cigarettes can be assessed on the basis of these item banks via one of the SFs, by using CATs, or through a tailored set of items selected for a specific research purpose.

    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.

    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.

    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.

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

    PubMed

    Tang, Kam Ki; Petrie, Dennis; Rao, D S Prasada

    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.

    Biomass forms the bulk of the energy supply of the developing world with the largest share consumed in the household sector as either fuelwood or charcoal for cooking, lighting and space heating. However there are a number of constraints facing the use of biomass if it is to be sustainable. Stephen Karekezi and Esther Ewagata of the African Energy Policy Research Network (AFREPREN) outline these constraints and discuss the modernisation of the traditional technologies now underway.

    1995-12-31

    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.

    PubMed Central

    Edelen, Maria Orlando; Tucker, Joan S.; Stucky, Brian D.; Hansen, Mark; Cai, Li

    2014-01-01

    Objective: Smoking is a coping strategy for many smokers who then have difficulty finding new ways to cope with negative affect when they quit. This paper describes analyses conducted to develop and evaluate item banks for assessing the coping expectancies of smoking for daily and nondaily smokers. Methods: Using data from a large 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 (DIF) analyses (according to gender, age, and ethnicity) to arrive at a unidimensional set of items for daily and nondaily smokers. We also evaluated performance of short forms (SFs) and computer adaptive tests (CATs) for assessing coping expectancies of smoking. Results: For both daily and nondaily smokers, the unidimensional Coping Expectancies item banks (21 items) are relatively DIF free and are highly reliable (0.96 and 0.97, respectively). A common 4-item SF for daily and nondaily smokers also showed good reliability (0.85). Adaptive tests required an average of 4.3 and 3.7 items for simulated daily and nondaily respondents, respectively, and achieved reliabilities of 0.91 for both when the maximum test length was 10 items. Conclusions: This research provides a new set of items that can be used to reliably assess coping expectancies of smoking, through a SF, CAT, or a tailored set selected for a specific research purpose.

  16. Bioenergy for sustainable development: An African context

    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.

    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.

    2014-01-01

    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

    2013-01-01

    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.

    NASA Technical Reports Server (NTRS)

    Rochon, Gilbert L.

    1989-01-01

    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

    1985-01-01

    For all the vast natural resources and the praiseworthy efforts of governments and peoples, the African economy still remains basically underdeveloped. Faced with this situation, there have been increased awareness and concern in recent years among political leaders, decision-makers, and socioeconomic planners of the fact that the chronic low-level productivity in almost all spheres of economic activity in that region can be attributed, to a large extent, to the low level of indigenous capability and appropriate utilization of science and technology. Few countries in Africa, however, as yet have a science and technology policy formulated toward long-term goals and objectives, and for overall economic and social development. There is, therefore, an urgent need to develop progressively the systems and methodology for identifying, selecting, and planning indigenous scientific and technological activity. International cooperation can be useful, but only within the context of a strong national capability. 14 references.

    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.

    Increased sediment loads within river catchments have well-documented detrimental effects on water quality and catchment management plans are required to address reduction and mitigation of these problems. In order do this it is essential that tools are available that deliver reliable sediment generation data at appropriate temporal and spatial scales. Currently, most sediment generation models do not include bank erosion individually as a sediment source. Therefore, to enable improved accuracy in predictions of future sediment pressures under environmental change, explicit modelling of the rates of sediment production by the bank erosion component of the catchment sediment budget is needed. In this study, an existing prototype national bank erosion index has been refined as part of a wider study modelling the response of catchment sediment budgets to climate and land use change scenarios. Using Geographical Information Systems (GIS) digitised overlays, channel migration rates and volume of bank eroded sediment were calculated for several catchments identified as priority areas by the England Catchment Sensitive Farming initiative (CSF). Relationships between volume of eroded sediment and factors controlling the rates of channel migration were investigated, including channel sinuosity, slope, upstream catchment area, and restriction of migration due to valley width. Significant correlations between bank erosion and sinuosity, upstream area and channel confinement were observed. A regression model to predict bank erosion from these factors was then developed. Sub-catchment areas which produced high residual values (between predicted and GIS-derived erosion estimates) were investigated in further detail. First, factors not included in the regression equation and thought to influence bank erosion were evaluated, including vegetation, bank composition, and anthropogenic influences. Second, the influence of channel planform geometry (curvature and sinuosity) on

    There is a need for precise but brief screening of mental health problems in a range of settings. The development of item banks to assess depression and anxiety has resulted in new adaptive and static screeners that accurately assess severity of symptoms. However, expansion to a wider array of mental health problems is required. The current study developed item banks for eight mental health problems: social anxiety disorder, panic disorder, post-traumatic stress disorder, obsessive-compulsive disorder, adult attention-deficit hyperactivity disorder, drug use, psychosis and suicidality. The item banks were calibrated in a population-based Australian adult sample (N=3175) by administering large item pools (45-75 items) and excluding items on the basis of local dependence or measurement non-invariance. Item Response Theory parameters were estimated for each item bank using a two-parameter graded response model. Each bank consisted of 19-47 items, demonstrating excellent fit and precision across a range of -1 to 3 standard deviations from the mean. No previous study has developed such a broad range of mental health item banks. The calibrated item banks will form the basis of a new system of static and adaptive measures to screen for a broad array of mental health problems in the community. PMID:27500552

    2016-01-01

    The objective of this study was to develop and validate a new diabetes self-management instrument for older African-Americans 65 years of age and older. The Self-Care Utility Geriatric African-American Rating (SUGAAR) was developed using the American Diabetes Association's standards for the management of type 2 diabetes in older adults and cognitive interviews with older African-Americans. The instrument underwent extensive review by a panel of experts, two rounds of cognitive interviews, and a pilot test before it was administered in an interview format to 125 community-dwelling older African-Americans. The instrument demonstrated content validity and significant, but modest, convergent validity with items from an established diabetes self-management instrument. Social workers and health care professionals can use the SUGARR to assess diabetes self-management and to identify areas for education and support for older African-Americans with type 2 diabetes.

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

    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.

    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.

  12. 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

    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.

    2003-01-01

    Wild bank voles (Clethrionomys glareolus) may develop diabetes in laboratory captivity. The aim of this study was to test whether bank voles develop type 1 diabetes in association with Ljungan virus. Two groups of bank voles were analyzed for diabetes, pancreas histology, autoantibodies to glutamic acid decarboxylase (GAD65), IA-2, and insulin by standardized radioligand-binding assays as well as antibodies to in vitro transcribed and translated Ljungan virus antigens. Group A represented 101 trapped bank voles, which were screened for diabetes when euthanized within 24 hours of capture. Group B represented 67 bank voles, which were trapped and kept in the laboratory for 1 month before being euthanized. Group A bank voles did not have diabetes. Bank voles in group B (22/67; 33%) developed diabetes due to specific lysis of pancreatic islet beta cells. Compared to nondiabetic group B bank voles, diabetic animals had increased levels of GAD65 (P < .0001), IA-2 (P < .0001), and insulin (P = .03) autoantibodies. Affected islets stained positive for Ljungan virus, a novel picorna virus isolated from bank voles. Ljungan virus inoculation of nondiabetic wild bank voles induced beta-cell lysis. Compared to group A bank voles, Ljungan virus antibodies were increased in both nondiabetic (P < .0001) and diabetic (P = .0015) group B bank voles. Levels of Ljungan virus antibodies were also increased in young age at onset of newly diagnosed type 1 diabetes in children (P < .01). These findings support the hypothesis that the development of type 1 diabetes in captured wild bank voles is associated with Ljungan virus. It is speculated that bank voles may have a possible zoonotic role as a reservoir and vector for virus that may contribute to the incidence of type 1 diabetes in humans. PMID:12745669

    Background The objective of this study was to compare four different criteria for diagnosing metabolic syndrome (MS) and to correlate sociodemographic data, liver enzymes, lipids, inflammation, and insulin resistance with MS definitions. Methods This cross-sectional study included a random number of 126 African bank employees from Brazzaville, Congo. Results The prevalence of MS varied according to the different definitions used: 4.8% under World Health Organization (WHO) criteria, 8.7% under the National Cholesterol Education Program Adult Treatment Panel III (NECP-ATPIII) criteria, 14.3% under the International Diabetes Federation (IDF) for Europe, and 15.9% by the IDF for Central Africa. According to the IDF, specific cutoff points for the erythrocyte sedimentation rate, ≥13 mm at first hour and ≥30 mm at second hour, defined MS for Central Africa. The best agreement was observed between the IDF for Europe and the IDF for Central Africa (Kappa = 0.938; P < 0.0001) criteria. The worst agreements were between the WHO and IDF for Central Africa (Kappa = 0.419; P < 0.0001) criteria and between the WHO and IDF for Europe (Kappa = 0.462; P < 0.0001) criteria. The NECP-ATPIII criteria did not agree with either the IDF for Europe or the IDF for Central Africa criteria. There was a significant relationship between female sex, aging, elevated liver enzymes, elevated phospholipids, high homeostasis model assessment of insulin resistance, and MS defined by the IDF for Central Africa. Conclusion The IDF definition of the MS modified for Central Africa provides higher prevalence estimates of MS than the estimates based on the NECP-ATPIII and IDF for Europe criteria. Liver enzymes, phospholipids, and homeostasis model assessment of insulin resistance should be included in clinical practice to stratify cardiovascular disease risk among Africans. PMID:22807636

    PubMed

    Hunter, Lora Rose; Schmidt, Norman B

    2010-03-01

    In this review, the extant literature concerning anxiety psychopathology in African American adults is summarized to develop a testable, explanatory framework with implications for future research. The model was designed to account for purported lower rates of anxiety disorders in African Americans compared to European Americans, along with other ethnoracial differences reported in the literature. Three specific beliefs or attitudes related to the sociocultural experience of African Americans are identified: awareness of racism, stigma of mental illness, and salience of physical illnesses. In our model, we propose that these psychological processes influence interpretations and behaviors relevant to the expression of nonpathological anxiety as well as features of diagnosable anxiety conditions. Moreover, differences in these processes may explain the differential assessed rates of anxiety disorders in African Americans. The model is discussed in the context of existing models of anxiety etiology. Specific follow-up research is also suggested, along with implications for clinical assessment, diagnosis, and treatment.

    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.

    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

  10. 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.

    Holt, Cheryl L.; Caplan, Lee; Schulz, Emily; Blake, Victor; Southward, Vivian L.; Buckner, Ayanna V.

    2013-01-01

    Research indicates that African Americans diagnosed with cancer tend to use religion in coping, however less is known about the specific role that religion plays in the coping process. Based on previous qualitative work, five instruments were developed to assess the role of religious involvement in cancer coping: God as helper, God as healer, Faith in healing, Control over cancer, and New perspective. The instruments were administered to 100 African Americans with cancer. Each exhibited high internal reliability, and concurrent and discriminant validity. These instruments may have applied value for the development of church-based cancer support/survivorship interventions. PMID:19383653

  18. Banking on fewer children: financial intermediation, fertility and economic development.

    PubMed

    Lehr, C S

    1999-01-01

    This study examines the influence of financial intermediation on fertility rate and labor allocation decisions. A panel Vector Autoregression model using three variables of interest, specifically, financial intermediation, fertility, and industrial employment data in 87 countries, was estimated. This convenient methodology allows the relationship between the variables to change over time. Findings indicate that the increase in wages led some households to shift from traditional labor intensive methods of production to modern sector firms. Since it is optimal for households in the modern sector to have fewer children then the labor allocation decision leads to a lower national fertility. Furthermore, results imply that the emergence and development of the financial intermediation sector will enhance modern sector employment and lower total fertility rates. Thus, the financial intermediation process is an important part of the overall developmental process.

  19. Implantation and early postimplantation development of the bank vole Clethrionomys glareolus, Schreber.

    PubMed

    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.

  20. Development of the PROMIS® Positive Emotional and Sensory Expectancies of Smoking Item Banks

    Introduction: The positive emotional and sensory expectancies of cigarette smoking include improved cognitive abilities, positive affective states, and pleasurable sensorimotor sensations. This paper describes development of Positive Emotional and Sensory Expectancies of Smoking item banks that will serve to standardize the assessment of this construct among daily and nondaily cigarette smokers. Methods: Data came from daily (N = 4,201) and nondaily (N =1,183) smokers who completed an online survey. To identify a unidimensional set of items, we conducted item factor analyses, item response theory analyses, and differential item functioning analyses. Additionally, we evaluated the performance of fixed-item short forms (SFs) and computer adaptive tests (CATs) to efficiently assess the construct. Results: Eighteen items were included in the item banks (15 common across daily and nondaily smokers, 1 unique to daily, 2 unique to nondaily). The item banks are strongly unidimensional, highly reliable (reliability = 0.95 for both), and perform similarly across gender, age, and race/ethnicity groups. A SF common to daily and nondaily smokers consists of 6 items (reliability = 0.86). Results from simulated CATs indicated that, on average, less than 8 items are needed to assess the construct with adequate precision using the item banks. Conclusions: These analyses identified a new set of items that can assess the positive emotional and sensory expectancies of smoking in a reliable and standardized manner. Considerable efficiency in assessing this construct can be achieved by using the item bank SF, employing computer adaptive tests, or selecting subsets of items tailored to specific research or clinical purposes.

    Introduction: Negative psychosocial expectancies of smoking include aspects of social disapproval and disappointment in oneself. This paper describes analyses conducted to develop and evaluate item banks for assessing psychosocial expectancies among daily and nondaily smokers. 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 psychosocial expectancies items for daily and nondaily smokers. We also evaluated performance of short forms (SFs) and computer adaptive tests (CATs) to efficiently assess psychosocial expectancies. Results: A total of 21 items were included in the Psychosocial Expectancies item banks: 14 items are common across daily and nondaily smokers, 6 are unique to daily, and 1 is unique to nondaily. For both daily and nondaily smokers, the Psychosocial Expectancies item banks are strongly unidimensional, highly reliable (reliability = 0.95 and 0.93, respectively), and perform similarly across gender, age, and race/ethnicity groups. A SF common to daily and nondaily smokers consists of 6 items (reliability = 0.85). Results from simulated CATs showed that, on average, fewer than 8 items are needed to assess psychosocial expectancies with adequate precision when using the item banks. Conclusions: Psychosocial expectancies of smoking can be assessed on the basis of these item banks via the SF, by using CAT, or through a tailored set of items selected for a specific research purpose.

    The Bristol Cord Blood Bank was established as a pilot project within existing health services to establish cost-effective recruitment, collection and processing suitable for use in the NHS should cord blood become a routine source of haemopoietic stem cells for transplantation in the UK. An important aim of the project was to evaluate the feasibility of establishing a midwifery-based collection network, thus utilising expertise already in place. Collection was performed on the delivery suite immediately after the placenta was delivered. The clinical experience of the midwife collector/counsellors allowed rapid pre-collection assessment of the condition of the cord and placenta. This prevented collection attempts from diseased or otherwise damaged placentas, leading to conservation of resources by preventing collection of most small volume donations. The bank was established within the National Blood Service, Bristol Centre to achieve Good Manufacturing Practice standards and ensure that processing was subject to the same stringency required for other sources of haemopoietic stem cells. Cord blood is an expensive resource. By utilising existing expertise in district Obstetric and National Blood Services, the Bristol Cord Blood Bank may serve as a model for health economic evaluation of cord blood banking of volunteer donations within the NHS.

  4. The role of small satellites in the development of the South African space programme

    NASA Astrophysics Data System (ADS)

    Martinez, Peter

    In the 1990s a team of scientists and engineers at Stellenbosch University built the first South African satellite to fly in space, the 64-kg Sunsat. This university-based satellite programme took advantage of the skills and facilities developed in the previous South African space programme of the 1980s and early 1990s, which had developed a much larger satellite (Greensat), but was cancelled in the mid-1990s prior to launch. Sunsat incorporated a number of novel capabilities for a microsatellite platform, and interest was shown in these technologies by other groups developing similar satellites. As the University was not the ideal environment to develop the commercial potential of these microsatellite technologies, a company called Sunspace was later established, thus creating industrial capacity in South Africa in a niche area of space technology. This new industrial capability, together with the infrastructure from the previous space programme, have created a foundation upon which to build the new South African space programme. This paper discusses the historical, current and possible future roles of small satellites in the development of the South African space programme.

    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.

    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.

    Induced pluripotent stem cells (iPSCs) derived from somatic cells of patients can be a good model for studying human diseases and for future therapeutic regenerative medicine. Current initiatives to establish human iPSC (hiPSC) banking face challenges in recruiting large numbers of donors with diverse diseased, genetic, and phenotypic representations. In this study, we describe the efficient derivation of transgene-free hiPSCs from human finger-prick blood. Finger-prick sample collection can be performed on a “do-it-yourself” basis by donors and sent to the hiPSC facility for reprogramming. We show that single-drop volumes of finger-prick samples are sufficient for performing cellular reprogramming, DNA sequencing, and blood serotyping in parallel. Our novel strategy has the potential to facilitate the development of large-scale hiPSC banking worldwide. PMID:24646489

    1975-01-01

    A community blood bank system is a multiorganizational program that is designed to supply the blood needs of a community. Participating in such a program are hospitals, a central blood bank, industrial donor groups, the American Red Cross, advisory committees, and the community at large. The underlying determinant of the community's success or failure with its blood program is the degree of cooperation among the various organizations. Intertwined with organizational considerations are the management problems associated with the operation of a responsive and efficient inventory control system. This paper reports on the development of a system for a community blood bank that is in its third year of operation. The system that has been developed can be operated manually by a part-time clerk. Details of the model include an integration of the donor scheduling function and the inventory control function. Simulated testing of the model has been conducted and full-scale implementation is awaiting the expansion of the known donor base.

    Purpose The purpose of this study was to calibrate the items for the Communicative Participation Item Bank (CPIB) using Item Response Theory (IRT). One overriding objective was to examine if the IRT item parameters would be consistent across different diagnostic groups, thereby allowing creation of a disorder-generic instrument. The intended outcomes were the final item bank and a short form ready for clinical and research applications. Methods Self-report data were collected from 701 individuals representing four diagnoses: multiple sclerosis, Parkinson’s disease, amyotrophic lateral sclerosis and head and neck cancer. Participants completed the CPIB and additional self-report questionnaires. CPIB data were analyzed using the IRT Graded Response Model (GRM). Results The initial set of 94 candidate CPIB items were reduced to an item bank of 46 items demonstrating unidimensionality, local independence, good item fit, and good measurement precision. Differential item function (DIF) analyses detected no meaningful differences across diagnostic groups. A 10-item, disorder-generic short form was generated. Conclusions The CPIB provides speech-language pathologists with a unidimensional, self-report outcomes measurement instrument dedicated to the construct of communicative participation. This instrument may be useful to clinicians and researchers wanting to implement measures of communicative participation in their work. PMID:23816661

    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.

    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. PMID:21992021

    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

    The Oubangui is a major right-bank tributary of the Congo River, draining an area of ~500,000 km² of mainly wooded savannahs. Here, we describe data on the physico-chemical characteristics and biogeochemistry of contrasting tributaries within the central Oubangui catchment collected during 3 field surveys between 2010 and 2012, with land use ranging from wooded savannahs to humid tropical rainforest. Compared to data from two years of sampling at high temporal resolution on the mainstem river in Bangui (Central African Republic), these tributaries show a remarkably wide range of biogeochemical signatures, from highly diluted blackwaters (low turbidity, pH, conductivity and total alkalinity (TA)) in rivers draining dense rainforests to those more typical for (sub)tropical savannah systems. Based on carbon stable isotope data (δ13C), the majority of sites show a corresponding dominance of C3-derived organic matter, with a tendency for increased C4 contributions the more turbid sites such as the Mpoko River. δ13C of dissolved organic carbon (DOC) were generally similar to those of particulate organic carbon (POC) across the different tributaries. δ13C of dissolved inorganic carbon (DIC) ranged between -28.1 ‰ in low-TA rainforest (blackwater) rivers to -5.8 ‰ in the mainstem Oubangui. These variations were strongly correlated to both partial pressure of CO2 (pCO2) and to the estimated contribution of carbonate weathering to total alkalinity, suggesting an important control of the dominant weathering regime (silicate versus carbonate weathering) on DIC and CO2 fluxes. All tributaries were consistently oversaturated in dissolved greenhouse gases (CH4, N2O, and CO2) with respect to atmospheric equilibrium, with highest levels observed in rivers draining rainforest vegetation. The high diversity observed within this subcatchment of the Congo River basin is equivalent to that observed in much larger, heterogeneous catchments, and underscores the importance of

    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

    African American youth face a number of challenges to prosocial development that the majority of American youth never encounter. Despite this, the research clearly documents that African American youth often are resilient in the face of these challenges. This article explores various factors associated with resilience in African American children and their implications for practitioners. An ecologic framework described by Bronfenbrenner is used as an organizing framework for understanding interventions at the micro-, mezzo-, and exo-system levels. In this article, the importance of identity formation, maintenance of social networks, and exposure to safe and supportive environments is expressed in conjunction with recommendations for practitioners. Practitioners are encouraged to stress the promotion of ethnic and racial identity and self-efficacy with the youth and their family and the involvement of the youth and family in meaningful activities through local community centers, schools, churches, and other organizations serving youth. A case study of an African American girl, from age 16 into adulthood and motherhood, is presented to illustrate the interplay between protective and risk factors.

    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

    Two generations of effort (from the 1920s to the 1960s) by pioneer African nationalists to use schools as the chief catalyst for national development strategy was followed by a generation of scholarship (from the 1960s to the 1980s) that was massively sceptical of their assumptions linking education, causally and positively, to development. The pioneers' writings and experiments, especially in southern Nigeria, are recounted in this paper's first section. The second section surveys the critical literature which experience, on the whole, justifies. The third and concluding section identifies a tangent of analysis which, it is argued, shifts the ground of the debate and supports more hopeful prospects for the current African generation's effort to link education and development productively. Evidence and comment are drawn principally from Anglophone West Africa, but there are inferences clearly to be drawn for general circumstances south of the Sahara.

    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

    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.

    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.

    2012-09-01

    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.

  15. A Phenomenological Investigation on the Role of Mentoring in the Academic Development of African American Male Secondary Students

    NASA Astrophysics Data System (ADS)

    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.

    2015-01-01

    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

    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.

    The Pediatric Evaluation of Disability Inventory (PEDI) is a useful clinical and research assessment but it has limitations in content, age range and efficiency. The purpose of this article is to describe the process used to develop the item bank for a new computerized adaptive test version of the PEDI (PEDI-CAT). An expanded item set and response scales were reviewed by clinician experts and examined at parent and clinician focus groups. Eleven parents participated in 32 cognitive interviews to examine content, format, and comprehension of items and responses. A revised set of self-care (n=76), mobility (n=78; walking aids n=13; wheelchair n=14) and social function (n=64) items with pictures and a 4-point ‘Difficulty’ scale were developed. Also, the PEDI’s Caregiver Assistance Scale was replaced by a ‘Responsibility Scale’ with 53 items. The new PEDI-CAT item bank covers a broader range of functional activities for children of all ages and abilities. PMID:20608855

    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. PMID:26846917

    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.

    Environmental problems as well as their related ecosystem stress and human health risk in China have raised wide concerns along with the rapid economic development in recent years. Numerous studies with a sharp increase in publication number have addressed the ubiquitous of anthropogenic chemicals in various environmental compartments and human tissues. However, very few data were available to clarify the temporal trend and to give the retrospective analysis of chemical pollution in China. Environmental Specimen Bank (ESB) is a system for the systematic collection and long-term storage of specimens, which has been established since the 1970s in developed counties and recognized as a fundamental complement for environmental monitoring and scientific research. Currently, the value of ESB is becoming more broadly recognized globally, and China is still at the early stage. This article described the history and status and put forwarded the future key points of Chinese ESB development for illustrating the intensive environmental changes in China and the world.

    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.

    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

    The parrot appears to provide a potentially unique animal model of handedness in humans, but few (if any) observational studies of early postnatal development of postural/motor asymmetries have been published. We studied three African Grey hatchlings, raised without human physical contact, for the first 5 months of life. All three animals failed to show consistent postural and/or motor asymmetries until the end of the 4 postnatal week. These results appear to be comparable to data from prior studies with human infants. Delayed development of lateral motor and/or postural preferences may represent an evolutionarily adaptive strategy for altricial animals.

    The present work describes the process of developing an item bank and short forms that measure the impact of asthma on quality of life (QoL) that avoids confounding QoL with asthma symptomatology and functional impairment. Using a diverse national sample of adults with asthma (N = 2032) we conducted exploratory and confirmatory factor analyses, and item response theory and differential item functioning analyses to develop a 65-item unidimensional item bank and separate short form assessments. A psychometric evaluation of the RAND Impact of Asthma on QoL item bank (RAND-IAQL) suggests that though the concept of asthma impact on QoL is multi-faceted, it may be measured as a single underlying construct. The performance of the bank was then evaluated with a real-data simulated computer adaptive test. From the RAND-IAQL item bank we then developed two short forms consisting of 4 and 12 items (reliability = 0.86 and 0.93, respectively). A real-data simulated computer adaptive test suggests that as few as 4-5 items from the bank are needed to obtain highly precise scores. Preliminary validity results indicate that the RAND-IAQL measures distinguish between levels of asthma control. To measure the impact of asthma on QoL, users of these items may choose from two highly reliable short forms, computer adaptive test administration, or content-specific subsets of items from the bank tailored to their specific needs.

    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.

    This study is concerned with the efficiency of World Bank projects in Egypt. The study seeks improvements in the methods of evaluating public sector projects in Egypt. To approaches are employed: (1) project identification to optimally allocate Egypt's and World Bank's resources; (2) project appraisal to assess the economic viability and efficiency of investments. The electricity sector is compared with the agriculture sector as a means of employing project identification for priority ordering of investment for development in Egypt. The key criteria for evaluation are the impacts of developments of each sector upon Egypt's national objectives and needs. These include employment opportunities, growth, alleviation of poverty, cross comparison of per capita consumption in each sector, economic rate of return, national security, balance of payments and foreign debt. The allocation of scarce investments would have been more efficient in agriculture than in electricity in meeting Egypt's national objectives and needs. World Bank lending programs in Egypt reveal a priority ordering of electricity over agriculture and rural development. World Bank development projects in Egypt have not been optimally identified, and its programs have not followed an efficient allocation of World Bank's and Egypt's resources. The key parameters in evaluating economic viability and efficiency of development projects are: (1) the discount rate (the opportunity cost of public funds); (2) the exchange rate; and (3) the cost of major inputs, as approximated by shadow prices of labor, water, electricity, and transportation for development projects. Alternative approaches to estimating the opportunity cost of public funds are made. The parameters in evaluating the efficiency of projects have not been accurately estimated in the appraisal stage of the World Bank projects in Egypt, resulting in false or misleading information concerning the economic viability and efficiency of the projects.

    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.

    The Southern African Development Community (SADC) is an international organization that has been in existence since 1980. Previously known as the Southern African Development Coordination Conference (SADCC), its primary aim was to coordinate development projects in order to lessen economic dependence on the then apartheid South Africa. Over the years, the coordination of such developmental projects has increasingly demanded a collective utilization of resources, such as energy, health and water sectors, among others. However, national boarders have also been pivotal in not only conflict management aspects, but also as protocolly agreed-upon component defining SADC`s contemporary international relations and legal regime. In the context of the accessibility and insufficiency of resources, our findings show that water as a resource has not only sparked inter-boarder issues, but also internal resistance from non-governmental organizations and major labor organizations in the SADC region. Policy formulation and implementation (under the international law umbrella) remain a greatest challenge in addressing the pressing issues of water privatization through political means.

  1. 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

    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

    Bone banks are necessary for providing biological material for a series of orthopedic procedures. The growing need for musculoskeletal tissues for transplantation has been due to the development of new surgical techniques, and this has led to a situation in which a variety of hospital services have been willing to have their own source of tissue for transplantation. To increase the safety of transplanted tissues, standards for bone bank operation have been imposed by the government, which has limited the number of authorized institutions. The good performance in a bone bank depends on strict control over all stages, including: formation of well-trained harvesting teams; donor selection; conducting various tests on the tissues obtained; and strict control over the processing techniques used. Combination of these factors enables greater scope of use and numbers of recipient patients, while the incidence of tissue contamination becomes statistically insignificant, and there is traceability between donors and recipients. This paper describes technical considerations relating to how a bone bank functions, the use of grafts and orthopedic applications, the ethical issues and the main obstacles encountered.

    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.

    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.

    African Americans have the highest burden of colorectal cancer (CRC) in the United States of America (USA) yet lower CRC screening rates than whites. Although poor screening has prompted efforts to increase screening uptake, there is a persistent need to develop public health interventions in partnership with the African American community. The aim of this study was to conduct focus groups with African Americans to determine preferences for the content and mode of dissemination of culturally tailored CRC screening interventions. In June 2013, 45-75-year-old African Americans were recruited through online advertisements and from an urban Veterans Affairs system to create four focus groups. A semi-structured interview script employing open-ended elicitation was used, and transcripts were analyzed using ATLAS.ti software to code and group data into a concept network. A total of 38 participants (mean age = 54) were enrolled, and 59 ATLAS.ti codes were generated. Commonly reported barriers to screening included perceived invasiveness of colonoscopy, fear of pain, and financial concerns. Facilitators included poor diet/health and desire to prevent CRC. Common sources of health information included media and medical providers. CRC screening information was commonly obtained from medical personnel or media. Participants suggested dissemination of CRC screening education through commercials, billboards, influential African American public figures, Internet, and radio. Participants suggested future interventions include culturally specific information, including details about increased risk, accessing care, and dispelling of myths. Public health interventions to improve CRC screening among African Americans should employ media outlets, emphasize increased risk among African Americans, and address race-specific barriers. Specific recommendations are presented for developing future interventions. PMID:25963898

  13. Regulatory challenges for GM crops in developing economies: the African experience.

    PubMed

    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.

    Abstract This is the first in a series of articles on primary care research in the African context. The aim of the series is to help build capacity for primary care research amongst the emerging departments of family medicine and primary care on the continent. Many of the departments are developing Masters of Medicine programmes in Family Medicine and their students will all be required to complete research studies as part of their degree. This series is being written with this audience in particular in mind – both the students who must conceptualise and implement a research project as well as their supervisors who must assist them. This article gives an overview of the African primary care context, followed by a typology of primary care research. The article then goes on to assist the reader with choosing a topic and defining their research question. Finally the article addresses the structure and contents of a research proposal and the ethical issues that should be considered. PMID:26245432

    "An Agenda for Action to Improve the Implementation of Population Programs in Sub-Saharan African in the 1990s" is a joint project of the World Bank, the UN Population Fund, the IPPF, the WHO and the African Development Bank. The goals of the agenda are to build public consensus and commitment to population activities, to bring together beneficiaries, implementors and policy makers with these groups to improve population program implementation, to share country program experiences, to make African institutions responsible for ("Africanize") the Agenda, or ultimately to include demographic factors in development. 20 African countries are the focus of the Agenda, grouped by region and language. Major issues include socio-cultural and economic roadblocks, poor transportation infrastructure, lack of community participation, no alternatives to early marriage for women, poor political commitment by decision-making or health ministries. Family planning programs can be improved by better contraceptive technology, program design, and human and financial resources for implementing programs. The methods by which the Agenda proposes to reach its goals are to do literature searches of action strategies, in-depth country analyses, inter-country sharing of experiences, analysis of implementation capability based on case studies, and analysis of contraceptive technology assisted by WHO's Special Programme of Research, Development and Research Training in Human Reproduction and the Population Council. The Agenda will be managed by a Population Advisor Committee, which is an African "think tank," and regional Country Group Task Forces, coordinated by the World Bank's Africa Technical Department.

    Umbilical cord blood transplants are now used to treat numerous types of immune- and blood-related disorders and genetic diseases. Cord blood (CB) banks play an important role in these transplants by processing and storing CB units. In addition to their therapeutic potential, these banks raise ethical and regulatory questions, especially in emerging markets in the Arab world. In this article, the authors review CB banking in five countries in the region, Jordan, Saudi Arabia, Egypt, Qatar, and the United Arab Emirates, selected for their different CB banking policies and initiatives. In assessing these case studies, the authors present regional trends and issues, including religious perspectives, policies, and demographic risk factors. This research suggests strong incentives for increasing the number of CB units that are collected from and available to Arab populations. In addition, the deficit in knowledge concerning public opinion and awareness in the region should be addressed to ensure educated decision-making.

    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.

    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.

    Founded in 1945 to meet the needs of post-war European reconstruction, the World Bank was formerly know as the International Bank for Reconstruction and Development. While Bank principals increasingly recognize the relationship between population growth and economic development, social investments in family planning have traditionally been less important than conventional Bank activities. Bank staff are generally maladroit in relating to demographic issues and favor carefully designed infrastructure projects over Third World social projects. Dr. Thomas Merrick has recently been appointed Senior Population Adviser to the World Bank. In this position, Dr. Merrick must accomplish the formidable task of convincing skeptical Bank economists that population is directly relevant to their work. He plans to argue the importance of population activities on a country- and issue-specific basis and stress population and family planning policies' bearing on capital formation, health, education, environment, job creation, urban development, and other Bank sectors. Dr. Merrick will also have to build up the number and competence of the World Bank's demographic staff. After having accomplished these internal tasks, the new Senior Population Adviser may also need to address the World Bank's tendency to work with recipient officials who give only low priority to borrowing for family planning.

    1999-10-01

    This investigation explored how African American mothers and their infants at the single-word stage of development structured their play and communicated with one another. Six mother-child dyads of low socioeconomic status (SES) and six of middle SES were observed at play. Few group differences were found, with the majority of the differences involving language behaviors. The middle-SES dyads included language goals more often in their play. Middle-SES infants initiated play verbally more frequently and produced over twice as many vocalizations as their low-SES peers. In addition, middle-SES mothers used a wider variety of words when playing with their children than their low-SES counterparts. A range of play styles was found within both groups. These were categorized into three general play styles: mothers and children actively involved in play; mothers' involvement varied; and children actively engaged and mothers attentive.

    An innovative curriculum designed to foster the development of social responsibility among pre-adolescent children was introduced at a rural Zambian primary school. The curriculum invoked Child-to-Child principles focusing on health education, advancing a synthesis of Western psychological theories and African cultural traditions. The teacher sought to democratize the educational process through cooperative learning in mixed-gender, mixed-social-class, and mixed-ability study groups. Learners engaged in community service activities and contributed to the nurturant care of younger children. Young adults interviewed seventeen years after completing the program recalled their experience and reflected on how it had promoted their personal agency, cooperative disposition, and civic responsibility in early adulthood.

    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.

    2016-06-01

    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.

    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.

    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.

    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. PMID:22709771

    • 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

    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.

    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.

    2016-06-01

    Partnership is a key idea in current debates about global health and development assistance, yet little is known about what partnership means to those who are responsible for operationalising it or how it is experienced in practice. This is particularly the case in the context of African health systems. This paper explores how health professionals working in global health hubs and the health systems of South Africa, Tanzania and Zambia understand and experience partnership. Drawing on semi-structured interviews with 101 professionals based in each country, Washington DC and Geneva between October 2012 and June 2013, the paper makes four key arguments. First, partnership has a legitimating function in global health policy processes for international development institutions, government agencies and civil society organisations alike. Second, the practice of partnership generates idiosyncratic and complicated relationships that health professionals have to manage and navigate, often informally. Third, partnership is shaped by historical legacies, critical events, and independent consultants. Fourth, despite being an accepted part of global health policy, there is little shared understanding of what good partnership is meant to include or resemble in practice. Knowing more about the specific socio-cultural and political dynamics of partnership in different health system contexts is critical to equip health professionals with the skills to build the informal relations that are essential to effective partnership engagement.

    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.

    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

  7. Implementing the millennium development food security goals Challenges of the southern African context

    Love, David; Twomlow, Steve; Mupangwa, Walter; van der Zaag, Pieter; Gumbo, Bekithemba

    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

    2010-06-01

    The present study examined the influence of cognitive development in the relationship between multiple types of racial discrimination and psychological well-being. A sample of 322 African American adolescents (53% female), aged 13-18, completed measures of cognitive development, racial discrimination, self-esteem and depressive symptoms. Based on the cognitive development measure, youth were categorized as having pre-formal or formal reasoning abilities. The results indicate no significant differences in perceptions of individual, cultural or collective/institutional racism between pre-formal reasoning and formal reasoning adolescents. However, the results do suggest that perceptions of collective/institutional racism were more harmful for the self-esteem of pre-formal reasoning youth than the self-esteem of formal reasoning youth. The implications for the racial discrimination literature among African American adolescents are discussed.

    Previous studies in dementia epidemiology have reported higher Alzheimer's disease rates in African-Americans when compared with White Americans. 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.

    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

Larval X. laevis were exposed to one of four nominal concentrations of atrazine (0, 1, 10, 25 microg atrazine/l) beginning 96 hr after fertilization and continuing through two years post-metamorphosis. Clutch size and survival of offspring were used as measurement endpoints to gauge reproductive success of the F1 frogs. Larval survivorship and time to metamorphosis were used to gauge developmental success of the F2 offspring from atrazine-exposed frogs. Testes in F1 and F2 frogs were examined for incidence of anomalies, such as testicular ovarian follicles, and sex ratios in F2 offspring were investigated to determine if exposure to atrazine caused trans-generational effects (effects on F2 individuals due to exposure of F1 individuals). There were no effects of any of the studied concentrations of atrazine on clutch size of F1 frogs. There were also no effects on hatching success or time to metamorphosis. Sex ratios did not differ between F2 offspring among treatments. There was no evidence to suggest a transgenerational effect of atrazine on spawning success or reproductive development of X. laevis. This is consistent with the presence of robust populations of X. laevis in areas where they are exposed to atrazine that has been used for several decades for weed control in production of corn. Our observations also are consistent with the results of most other studies of frogs where no effects were found to be associated with exposure to atrazine. Our data do not support the hypothesis that atrazine significantly affects reproductive fitness and development of frogs.

  12. Professional development and poststructural analysis: Stories of African-American science teachers

    2003-10-01

    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.

  14. Developmental and ethnic issues experienced by emerging adult African American women related to developing a mature love relationship.

    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. PMID:22224965

  15. Effect of water hardness on oocyte quality and embryo development in the African clawed frog (Xenopus laevis).

    2004-04-01

    Husbandry and health of the African clawed frog, Xenopus laevis, greatly influences the quality of oocytes produced. One factor affecting oocyte quality is the water conditions in which females are maintained. Dechlorination and adequate salt concentration are known to affect oocytes, but water hardness has not been considered an important factor in Xenopus husbandry by the research community. We found that, when females were kept in soft water or water with marine salts alone, even when it was cooled to 17 to 18 degrees C, the quality of oocytes decreased; only 20 to 25% of resulting embryos developed to tailbud stages. Survival and normal development of embryos increased significantly within one month of addition to the laboratory housing water of salts that mimic conditions in African Rift Valley lakes. These salts greatly increased water hardness; development of embryos to tailbud stages remained high (50 to 70% on average) for more than a year after their addition to the water housing females. Water from South African ponds where X. laevis are collected, and from wells used by the major suppliers of X. laevis, also was moderately to very hard. Our results suggest that X. laevis is naturally adapted to hard water, and indicate that increasing general hardness during laboratory housing is more important for oocyte quality and embryo development than is increasing carbonate hardness (alkalinity) in the water used to house females.

    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. PMID:19657823

  17. What some African development plans say on population related issues in development.

    1983-01-01

    This discussion reviews what development plans say about population related issues in development in the countries of Botswana, Kenya, Lesotho, Senegal, Nigeria, Ivory Coast, Seychelles, Sierra Leone, Somalia Democratic Republic, Sudan, The United Republic of Cameroon, Tanzania, Zambia, and Zimbabwe. Botswana's 1970-73 development plan recognized the need to have fewer children who would be better fed, well clothed, properly housed, and better educated. The government set a target of population growth not to exceed 2.5% for the 1970-80 period. The government of Kenya has expressed much concern about population growth and is devoted to continuing and strengthening the official family planning program instituted in 1967. Lesotho's 1980-81 to 1984-85 development plan emphasizes the need to enhance the well-being of the rural population. The orientation of the health sector strategy is towards primary health care, health education, family planning, water supply, sanitation, and nutrition. Nigeria's 1975-80 plan indicates that demographic factors do not appear as yet to constitute a significant or serious obstacle to domestic economic progress. The objective of the Ivory Coast's 1976-80 plan for economic, social, and cultural development is to increase population since the Ivory Coast still seems to be an underpopulated country. The 1979-83 National Development Plan of Seychelles includes the following objectives: to remedy the housing problem, to achieve full employment, and to introduce responsible family planning. Sierra Leone's development plan for 1974-75 to 1978-79 did not indicate a need to decrease population growth. Population variables in relation to development are not well articulated in the plan of the Somalia Democratic Republic. Like many other developing countries, Sudan's plan has objectives to improve all aspects of the standard of living. It recognizes the serious problem of absorbing a larger population in urban areas. In Tanzania family planning is

    Fundamental cryobiological characteristics of spermatozoa from threatened or endangered species must be determined for successful cryopreservation techniques to be established. In this study, spermatozoa from four diverse species, impala (Aepyceros melampus), wart hog (Phacochoerus aethiopicus), elephant (Loxodonta africana), and lion (Panthera leo), were collected by electroejaculation or epididymal aspiration. Spermatozoal plasma membrane permeability to water (hydraulic conductivity, Lp) and the osmotically inactive fraction of the sperm cell (Vb) were determined from each species. Changes in cell volume were measured over time using an electronic particle counter. A Kedem-Katchalsky membrane transport model was used to theoretically characterize the data to determine Lp and Vb for each species. In addition to determining plasma membrane characteristics, spermatozoa were also studied to determine their sensitivity to low temperatures and to permeating cryoprotectant solutes. Cells maintained at room temperature (20-22 degrees C) were slowly or rapidly exposed to cold temperatures (1-4 degrees C), and percent motility was estimated to determine the sensitivity of the cells to cooling. Spermatozoa were also in media containing 1 M glycerol, dimethyl sulfoxide or ethylene glycol, and percent motility was measured at 15, 30 and 60 min intervals to determine the sensitivity of the cells to the cryoprotectant agent over time. Results indicate that sperm motility is significantly effected by decreased temperatures and the presence of cryoprotectant agents.

  1. Psychopathology, adversity, and creativity: diversifying experiences in the development of eminent African Americans.

    PubMed

    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.

It is these ethical issues—which are often not acknowledged by commentators—that are the subject of this paper. It asks why there should be a focus on the poor, and explores the link between improving the health of the poor, and reducing health inequalities between the poor and better-off. It discusses difficult ethical issues at both the global level (including debt relief and the link between country ownership and donor commitment) and the country level (including user fees and whether providing assistance to the non-poor may in the long run be a way of helping the poor).

    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

    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.

  8. 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.

    Researchers at the Desert Research Institute (DRI) are conducting SAHRA-related research aimed at developing an integrated physical and engineering hydrologic model for the purpose of investigating the feasibility of water banking and markets in the Rio Grande watershed. The main components of the integrated model will include a detailed representation of system behavior in (1) headwater areas (snow accumulation and melt); (2) surface reservoirs and conveyance systems (operational surface reservoirs, river routing, and diversions/returns); (3) regional and near river aquifers; (4) agricultural demand and uses; and (5) urban and industrial demand and uses. Existing models of several of these components have been identified and will be included, to some degree, in the final integrated model (e.g., URGWOM, MMS-PRMS, and various USGS groundwater models). Coupling of existing and new models of each component to create the final completely integrated model requires a detailed understanding of the problem requirements (what questions are being asked) and the data (what information is available in the hydrologic data). Once developed and tested, the integrated model will be used with the economic "Market" model and "Behavior" model to investigate several water market and banking scenarios.

    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

    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.

    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.

    Increasingly, African American churches have been called upon to assist in efforts to address HIV/AIDS in underserved communities. African Americans churches may be well-positioned to provide HIV education, screening, and support services, particularly if they are equipped with church-appropriate, easy-to-deliver HIV tools that can be implemented through the naturalistic church environment. To inform the development of a church-based HIV tool kit, we examined church capacity with African American church leaders (N = 124 participants; n = 58 churches represented by senior pastors). Nearly all participants (96%) wanted to learn more about HIV and how to discuss it with their parishioners. Regarding church capacity, most of their representative churches held three regular services each week, facilitated various inreach and community outreach ministries, and had paid staff and computers. Also, many of their churches facilitated HIV/AIDS education/prevention and adolescent sex education activities. Guided by church capacity findings, an ecological framework, and a CBPR approach, we describe the resulting church-based HIV Tool Kit that "fits" naturalistically within a multilevel church infrastructure, builds upon churches' HIV-related experience, and equips faith leaders to efficiently promote HIV services with the communities they serve.

    Although there is general agreement that patient satisfaction is an integral component of service quality, there is a paucity of South African research on reliable and valid satisfaction measures and the effects of health status on satisfaction. A 25-item patient satisfaction scale was developed and tested for evaluating the quality of health care for black diabetic outpatients. It was hypothesised that: (1) the underlying dimensions of patient satisfaction were interpersonal and organisational; and (2) patients in poor health would be less satisfied with the quality of their care than patients in good health. The questionnaire was administered to 263 black outpatients from Pretoria Academic Hospital and Kalafong Hospital. Factor analysis was conducted on the patient satisfaction scale and three factors, accounting for 71% of the variance, were extracted. The major items on Factor I were helpfulness, communication, support and consideration, representing the interpersonal dimension. Factors II and III were mainly concerned with service logistics and technical expertise, with the emphasis on waiting time, follow-up and thoroughness of examination. The three factors had excellent reliability coefficients, ranging between 0.82 (technical), 0.85 (logistics) and 0.98 (interpersonal). Multiple analyses of co-variance showed that patients in poor general health were significantly less satisfied with the logistical (p = 0.004) and technical (p = 0.007) quality of their care than patients in good health; patients in poor mental health were significantly less satisfied with the interpersonal quality of their care (p = 0.05) than patients in good mental health. These findings provided support for both hypotheses and suggested that patients in poor health attend to different aspects of their care than patients in good health. Of more importance to clinical practice, the results endorsed the need for a multidisciplinary health team comprising nurse/social worker (Factor I

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.

    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.

    A number of analyses have been performed using the DORCA program for several NASA-funded Aerospace Corporation studies in the past few years. The data decks containing the input data for these analyses have been compiled and are submitted, under separate cover. A few of the data decks are full (basic) decks containing every data item and are used as reference decks in the data bank. The other data decks were obtained by differencing a full deck with respect to one of the reference decks. Using the DORMAN program, a full deck can be recreated from the modified deck and its reference deck when and if desired. The content and structure of the data bank are described. A description of each of these data decks is presented. Three of the cases that are included in this volume have become so widely recognized and accepted that additional descriptive material has been provided. The three cases are: Case 500 Costs, Case 506 Costs, and Case 403.

    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

    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.

    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.

  12. Multinational, freshwater biomonitoring programs in the developing world: lessons learned from African and Southeast Asian river surveys.

    PubMed

    2007-05-01

    Biomonitoring programs are widely used in developed countries. They also offer many advantages in assessing ecological consequences of perturbations in developing countries, including reducing the equipment-operation, maintenance, and training costs associated with physicochemical monitoring. Three case histories of river biomonitoring using freshwater organisms (fish, benthic macroinvertebrates, diatoms, zooplankton) are described that involve (1) documentation of environmental effects from long-term, large-scale applications of insecticides to control insect-vectors of river blindness (onchocerciasis) in 11 West African countries; (2) water quality assessments and restoration planning in and around national parks in three East African countries; and (3) evaluation of overall ecological health of the Lower Mekong River in four Southeast Asian countries. As in developed countries, benthic macroinvertebrates are the organisms most widely used in biomonitoring in developing countries. Conflicting opinions of system resilience and whether expected changes are within natural variation may result in differences in underlying hypotheses proposed, study designs implemented, and study execution; each may lead to uncorrectable bias. Direct transfers of approaches used from developed to developing countries are often appropriate; however, techniques dependent on pollution-tolerance values are often region specific and not transferable. Typically expressed concerns about applications of biomonitoring in developing countries include poor coordination among agencies; lack of legislation, identification keys, and trained personnel; and incomplete information on how tropical rivers function. Problems are real but solvable, as evident from accomplishments in several multicountry programs in developing countries. Developed countries requiring coordinated monitoring of international rivers may benefit from examining successful programs under way in developing countries.

    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. PMID:27131416

    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.

    The purpose of this study was to examine the role of neighborhood disadvantage and perceptions of neighborhood on the development of aggressive behavior among a sample of urban low-income African American middle school aged youth (mean age = 11.65 years). Results of hierarchical linear modeling indicated that youth experienced significant changes in rates of aggression across the three middle school years, and that on average, negative youth perceptions of neighborhood predicted increases in aggression. Both parent and youth perceptions of neighborhood disadvantage trended toward significance as a moderator between objective neighborhood characteristics and aggression. These results are in accordance with past research, which suggests that personal evaluations of the disadvantage of a neighborhood influence child development and behavior. Future studies should examine the role that perceptions play in youth development, as well as in interventions geared towards thwarting youth aggression.

    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.

    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

    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

    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

This is particularly true in our communities of interest in rural eastern North Carolina. Although most recent efforts to prevent HIV attempt to address multiple contributing factors, we have found few multilevel HIV interventions that have been developed, tailored or tested in rural communities for African Americans. We describe how Project GRACE integrated Intervention Mapping (IM) methodology with community based participatory research (CBPR) principles to develop a multi-level, multi-generational HIV prevention intervention. IM was carried out in a series of steps from review of relevant data through producing program components. Through the IM process, all collaborators agreed that we needed a family-based intervention involving youth and their caregivers. We found that the structured approach of IM can be adapted to incorporate the principles of CBPR. PMID:20528128

    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. PMID:23729945

    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

    Indonesia depends heavily on revenues from the export of LNG and oil, the availability of which appears to be decreasing. It is therefore making a strong effort to accelerate development of a domestic natural gas industry. A high priority has been given to the conversion of power plants and city gas systems, including local industries and commercial facilities, from liquid fuels to natural gas. This will release more oil for export, help to meet the objectives of Repelita V, and provide substantial environmental benefits. The World Bank recently provided loans to the Indonesian Government for two projects that are aimed at substituting natural gas for oil and manufactured gas in domestic markets. One project involves expansion of the gas distribution systems of Indonesia's natural gas utility (PGN) in three cities: Jakarta and Bogor in Java, and Medan in Sumatra. The project also includes training programs for PGN staff and an energy pricing policy study to be carried out by Indonesia's Ministry of Mines and Energy. The second project involves expansion of the supply of natural gas for Surabaya and twelve other towns in its vicinity in East Java, and further expansion of Medan's supply system. Technical assistance will be provided to enhance the skills ofPGN and the Ministry of Mines and Energy, and a Gas Technology Unit similar to the Institute of Gas Technology will be established at Indonesia's Research and Development Center for Oil and Gas (LEMIGAS) in Jakarta. 14 refs., 3 figs., 11 tabs.

    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

    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

    Objective To describe the development and psychometric properties of the SCI-QOL Psychological Trauma item bank and short form. Design Using a mixed-methods design, we developed and tested a Psychological Trauma item bank with patient and provider focus groups, cognitive interviews, and item response theory based analytic approaches, including tests of model fit, differential item functioning (DIF) and precision. Setting We tested a 31-item pool at several medical institutions 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 Veterans Administration hospital. Participants A total of 716 individuals with SCI completed the trauma items Results The 31 items fit a unidimensional model (CFI=0.952; RMSEA=0.061) and demonstrated good precision (theta range between 0.6 and 2.5). Nine items demonstrated negligible DIF with little impact on score estimates. The final calibrated item bank contains 19 items Conclusion The SCI-QOL Psychological Trauma item bank is a psychometrically robust measurement tool from which a short form and a computer adaptive test (CAT) version are available.

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

    NASA Astrophysics Data System (ADS)

    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.

    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

    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.

    Ubbels, Geertje A.; Berendsen, Willem; Kerkvliet, Sonja; Narraway, Jenny

    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 inted 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.

    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

    Written materials about breast cancer screening for African American women with low literacy skills are needed. Available materials were not at or below third-grade reading levels, were not culturally sensitive, and were not accurate in illustrating correct breast self-examination (BSE) techniques. Focus groups representing the target population helped the authors design a pamphlet describing how to perform BSE and a motivational picture book to help women overcome barriers to screening. The authors chose a food theme for the cover of the pamphlet written at a third-grade level and suggested a photographic version. In the motivational book, two women address barriers to screening and replace myths and fears with facts and actions. Data from 162 women showed that they learned from both the photographic and illustrated versions. Women in the photographic group found significantly more lumps in the silicone models, so the authors chose that version to use in final testing. Finally, nurses pretested a group of patients before they reviewed the materials and post-tested another group after they reviewed them. The group who had reviewed the materials had greater knowledge of and intent to follow the guidelines and received higher scores on BSE techniques.

  10. AIDS -- why African successes are scoffed.

    PubMed

    Ankomah, B

    1996-09-01

    Pressures to create a profitable Third World market for Western drugs may have led to the suppression of acquired immunodeficiency syndrome (AIDS) treatments developed in Africa. Six years before four Western pharmaceutical companies announced the discovery of a three-drug regimen that appears to produce remission in some patients infected with human immunodeficiency virus (HIV), Ugandan physician Dr. Charles Ssali had developed a similar formulation. Beginning in 1989, Dr. Ssali gave HIV-infected patients at his Kampala clinic a preparation, Miriandina, containing 27 naturally occurring anti-oxidants and micronutrients that stimulate the immune system and prevent progression to AIDS. To date, he has treated over 12,000 patients, with an 80% success rate. His first patient, who presented in 1989 with full-blown AIDS, is alive and symptom-free. Miriandina is taken for 12-18 months, at a cost of only US $0.50 per tablet ($600 for six months of treatment). Another herbal formulation, Pearl Omega, developed by scientist Arthur Obel with funds provided by the Kenyan government, has produced a similar reversal of AIDS symptoms. However, international donor organizations and the AIDS establishment have refused to fund these African-based efforts or to publicize their success. It is suggested that this reflects a plan to force African countries to take out World Bank loans to finance the more expensive ($8300 a course) Western-based protease inhibitors.

    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.

    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

    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

    Artificial feeding assays were used to study the effect of purified galactose-specific lectins from African yam beans (Sphenostylis stenocarpa) on development of larvae of the cowpea weevil, Callosobruchus maculatus (Coleoptera : Bruchidae) and the legume pod-borer, Maruca vitrata (Lepidoptera : Pyrialidae). Inhibition of development of C. maculatus was observed when larvae were fed on artificial cowpea seeds containing 0.2%, 2.0% and 5.0% (wt/wt) of dietary lectin. Larval mortality was between 30% and 88%, while delays in total developmental time ranged between 7 and 13 days. The lectin had no effect on development of larvae of M. vitrala, when tested through topical artificial diet incorporation assays, except at the extremely high dose of 35% dietary level.

    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

    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

    Reducing new HIV/STD infections among at-risk adolescents requires developing and evaluating evidence-based health communication approaches. Research over-whelmingly 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. PMID:24093220

    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. Participants were a community-based sample of 2,450 girls from the Pittsburgh Girls Study (PGS) 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 females 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.

    Mahfood, Denise Marcia

    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.

    Purpose Neuro-QOL provides a clinically relevant and psychometrically robust health-related quality of life (HRQL) assessment tool for both adults and children with common neurological disorders. We now report the psychometric results for the adult tools. Methods An extensive research, survey and consensus process was used to produce a list of 5 priority adult neurological conditions (stroke, multiple sclerosis, Parkinson’s disease, epilepsy and ALS). We identified relevant health related quality of life (HRQL) domains through multiple methods and data sources including a comprehensive review of the literature and literature search, expert interviews and surveys and patient and caregiver focus groups. The final domain framework consisted of 17 domains of Physical, Mental and Social health. There were five phases of item development: (1) identification of 3,482 extant items, (2) item classification and selection, (3) item review and revision, (4) cognitive interviews with 63 patients to assess their understanding of individual items and (5) field testing of 432 representative items. Participants and Procedures Participants were drawn from the US general population and clinical settings, and included both English and Spanish speaking subjects (N = 3,246). Confirmatory factor analysis (CFA) was used to evaluate the dimensionality of unidimensional domains. Where the domain structure was previously unknown, the dataset was split and first analyzed with exploratory factor analysis and then CFA. Samejima’s graded response model (GRM) was used to calculate IRT parameters. We further evaluated differential item functioning (DIF) on gender, education and age. Results Thirteen unidimensional calibrated item banks consisting of 297 items were developed. All of the tested item banks had high reliability and few or no locally dependent items. The range of item slopes and thresholds with good information are reported for each of the item banks. The banks can support CAT and

    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.

    We have employed a multifaceted approach to sedimentary provenance analysis in order to assess the timing and magnitude of tectonic events, sedimentation, and landscape development in the Western Branch of the East African Rift System. Our approach, termed 'Sedimentary Triple Dating', integrates: (1) U-Pb dating via LA-ICPMS; (2) fission track; and (3) (U-Th)/He thermochronology of detrital zircon and apatite. We integrate geochronology, thermochronology, and provenance analysis to relate the initiation of rifting events to regional dynamic uplift, sedimentation patterns, and interpret the far-reaching climatic and evolutionary effects of fluctuating rift flank topography in the Rukwa Rift, a segment of the Western Branch. This work provides additional data to support the recent concept of synchronous development of the Western and Eastern branches of the East African Rift System ~25 Ma, and better constrains the age, location and provenance of subsequent rifting and sedimentation events in the Rukwa Rift Basin. Investigation of well cuttings and outcrop samples from the Neogene-Recent Lake Beds Succession in the Rukwa Rift Basin revealed a suite of previously unrecognized tuffaceous deposits at the base of the succession. A population of euhedral, magmatic zircons from a basal Lake Beds tuff and Miocene-Pliocene detrital zircons from well cuttings suggest that Neogene rift reactivation and volcanism began ~9-10 Ma. This timing is consistent with demonstrated rifting in Uganda and Malawi, as well as with the initiation of volcanism in the Rungwe Volcanic Province at the southern end of the Rukwa Rift, and the estimated development of Lake Tanganyika to the north. Moreover, there appear to be a suite of unconformity bounded stratigraphic units that make up the Lower Lake Beds succession, and detrital zircon maximum depositional ages from these units suggests episodic sedimentation in the rift, punctuated by long hiatuses or uplift, rather than steady subsidence and

    Objective To develop a spinal cord injury (SCI)-focused version of PROMIS and Neuro-QOL social domain item banks; evaluate the psychometric properties of items developed for adults with SCI; and report information to facilitate clinical and research use. Design We used a mixed-methods design to develop and evaluate Ability to Participate in Social Roles and Activities and Satisfaction with Social Roles and Activities items. Focus groups helped define the constructs; cognitive interviews helped revise items; and confirmatory factor analysis and item response theory methods helped calibrate item banks and evaluate differential item functioning related to demographic and injury characteristics. Setting Five SCI Model System sites and one Veterans Administration medical center. Participants The calibration sample consisted of 641 individuals; a reliability sample consisted of 245 individuals residing in the community. Results A subset of 27 Ability to Participate and 35 Satisfaction items demonstrated good measurement properties and negligible differential item functioning related to demographic and injury characteristics. The SCI-specific measures correlate strongly with the PROMIS and Neuro-QOL versions. Ten item short forms correlate >0.96 with the full banks. Variable-length CATs with a minimum of 4 items, variable-length CATs with a minimum of 8 items, fixed-length CATs of 10 items, and the 10-item short forms demonstrate construct coverage and measurement error that is comparable to the full item bank. Conclusion The Ability to Participate and Satisfaction with Social Roles and Activities CATs and short forms demonstrate excellent psychometric properties and are suitable for clinical and research applications.

    Water resources have been one of the most important areas of World Bank lending during the past three decades. Through its support for sector work and investments in irrigation, water supply, sanitation, flood control, and hydropower, the Bank has contributed to the development of many countries and helped provide essential services to many communities. Moreover, the Bank and governments have not taken sufficient account of environmental concerns in the management of water resources.

    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 on the nearby storms has been the subject of considerable debate. In this study, the Weather Research and Forecasting model is used to investigate the radiative effect of dust on the development of AEWs during August and September, the months of maximumtropical cyclone activity, in years 2003–07. The simulations show that dust radiative forcing enhances the convective instability of the environment. As a result, mostAEWsintensify 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. The authors conclude that dust radiative forcing, albeit small, serves as a catalyst to promote local convection that facilitates AEW development.

    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.

    Classical swine fever (CSF) and African swine fever (ASF) are both highly contagious diseases of domestic pigs and wild boar and are clinically indistinguishable. For both diseases, antibody detection is an integral and crucial part of prevention and control measures. The purpose of our study was to develop and initially validate a duplex pen-side test for simultaneous detection and differentiation of specific antibodies against CSF virus (CSFV) and ASF virus (ASFV). The test was based on the major capsid protein VP72 of ASFV and the structural protein E2 of CSFV, both considered the most immunogenic proteins of these viruses. The performance of the pen-side test was evaluated using a panel of porcine samples consisting of experimental, reference, and field sera, with the latter collected from European farms free of both diseases. The new lateral flow assay was able to detect specific antibodies to ASFV or CSFV, showing good levels of sensitivity and specificity. These preliminary data indicate the potential of the newly developed pen-side test for rapid differential detection of antibodies found in the 2 diseases, which is of particular importance in the field and in front-line laboratories where equipment and skilled personnel are limited and control of ASF and CSF is crucial.

    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.

    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

    Lurie, P; Hintzen, P; Lowe, R A

    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.

    2001-11-01

    The effects of 17alpha-methyltestosterone on seminal vesicle development in the African catfish, Clarias gariepinus, were investigated in an attempt to improve semen collection from this species. Treatment of larvae with dietary 17alpha-methyltestosterone at 50 mg kg(-1) for days 12-33 or days 12-40 after hatching, or at 20 mg kg(-1) for days 12-26, 12-33, 12-40 or 12-47 after hatching inhibited the development of the seminal vesicle finger-like extensions in male catfish, but did not affect the sex ratio. The minimum effective dose and period of treatment to inhibit seminal vesicle development in all male catfish treated with 17alpha-methyltestosterone was 20 mg kg(-1) for days 12-40 after hatching. Male catfish from this treatment group developed normal testes that, in some cases, contained a few oocytes, which tended to disappear before sexual maturation. After sexual maturation, the semen release response was evaluated in males with incomplete seminal vesicles. Fluid with viable spermatozoa was obtained after two consecutive injections of carp pituitary suspension, from 10 of 19 males that had been fed 20 mg 17alpha-methyltestosterone kg(-1) for days 12-40 or days 12-47 after hatching, but from only 4 of 15 males that did not receive any dietary steroid. Intratesticular semen quality was not affected by 17alpha-methyltestosterone treatment. The results of this study demonstrate that the absence of seminal vesicle extensions induced by treatment with 17alpha-methyltestosterone facilitated the collection of semen by stripping from this species of fish.

    Context Family satisfaction is an important and commonly used research measure. Yet current measures of family satisfaction are lengthy and may be unnecessarily burdensome – particularly in the setting of serious illness. Objectives To use an item bank to develop short-forms of the FAMCARE scale, which measures family satisfaction with care. Methods To shorten the existing 20-item FAMCARE measure, item response theory parameters from an item bank were used to select the most informative items. The psychometric properties of the new short-form scales were examined. The item bank was based on data from family members from an ethnically diverse sample of 1983 patients with advanced cancer. Results Evidence for the new short-form scales supported essential unidimensionality. Reliability estimates from several methods were relatively high, ranging from 0.84 for the five-item scale to 0.94 for the 10-item scale across different age, gender, education, ethnic and relationship groups. Conclusion The FAMCARE-10 and FAMCARE-5 short-form scales evidenced high reliability across sociodemographic subgroups, and are potentially less burdensome and time-consuming scales for monitoring family satisfaction among seriously ill patients.

    This paper reports part of a bigger study whose aim was to develop an empowerment model that could be used to enhance nurse leaders' participation in health policy development. A Delphi survey was applied which included the following criteria: expert panelists, iterative rounds, statistical analysis, and consensus building. The expert panelists were purposively selected and included national nurse leaders in leadership positions at the nursing professional associations, nursing regulatory bodies, ministries of health, and universities in East Africa. The study was conducted in three iterative rounds. The results reported here were gathered as part of the first round of the study and that examined the extent of nurse leaders' participation in health policy development. Seventy-eight (78) expert panelists were invited to participate in the study, and the response rate was 47%. Data collection was done with the use of a self-report questionnaire. Data analysis was done by use of SPSS and descriptive statistics were examined. The findings indicated that nurse leaders participate in health policy development though participation is limited and not consistent across all the stages of health policy development. The recommendations from the findings are that health policy development process needs to be pluralistic and inclusive of all nurse leaders practicing in positions related to policy development and the process must be open to their ideas and suggestions.

  10. History of the development of the East African Rift System: A series of interpreted maps through time

    2015-01-01

    This review paper presents a series of time reconstruction maps of the 'East African Rift System' ('EARS'), illustrating the progressive development of fault trends, subsidence, volcanism and topography. These maps build on previous basin specific interpretations and integrate released data from recent petroleum drilling. N-S trending EARS rifting commenced in the petroliferous South Lokichar Basin of northern Kenya in the Late Eocene to Oligocene, though there seem to be few further deep rifts of this age other than those immediately adjoining it. At various times during the Mid-Late Miocene, a series of small rifts and depressions formed between Ethiopia and Malawi, heralding the main regional rift subsidence phase and further rift propagation in the Plio-Pleistocene. A wide variation is thus seen in the ages of initiation of EARS basins, though the majority of fault activity, structural growth, subsidence, and associated uplift of East Africa seem to have occurred in the last 5-9 Ma, and particularly in the last 1-2 Ma. These perceptions are key to our understanding of the influence of the diverse tectonic histories on the petroleum prospectivity of undrilled basins.

    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.

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

    PubMed Central

    2013-01-01

    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.

    PubMed

    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.

    PubMed

    2008-01-01

    The advent of highly active antiretroviral therapy (HAART) has transformed human immunodeficiency virus (HIV)/AIDS into a manageable chronic disorder. Clinical care, however, needs to address the metabolic, anthropometric, and cardiovascular changes associated with HIV infection and HAART. Studies in developing countries suggest an increasing incidence of HIV-associated cardiometabolic syndrome (CMS), especially in urban settings. Predictions indicate that the greatest increase in the prevalence of diabetes will occur in Africa over the next 2 decades due to lifestyle changes. This, coupled with increased access to HAART, may exponentially increase the prevalence of CMS in developing countries, where HIV infection is prevalent. Appropriate evaluation and intervention programs need to be implemented in the developing world, especially sub-Saharan Africa, to curtail HIV-related CMS. This should include routine cardiovascular risk assessments, management of HIV infection with more "metabolically friendly" HAART, and encouragement of lifestyle modifications, particularly smoking cessation, weight management, regular exercise, and adherence to a healthy diet.

    Anwar, Wagida A. . E-mail: wagidaanwar@yahoo.com

    2005-09-01

    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.

    ABSTRACT The initial phases of acute human immunodeficiency virus type 1 (HIV-1) infection may be critical for development of effective envelope (Env)-specific antibodies capable of impeding the establishment of the latent pool of HIV-1-infected CD4+ T cells, preventing virus-induced immune hyperactivation to limit disease progression and blocking vertical virus transmission. However, the initial systemic HIV-1 Env-specific antibody response targets gp41 epitopes and fails to control acute-phase viremia. African-origin, natural simian immunodeficiency virus (SIV) hosts do not typically progress to AIDS and rarely postnatally transmit virus to their infants, despite high milk viral loads. Conversely, SIV-infected rhesus macaques (RMs), Asian-origin nonnatural SIV hosts, sustain pathogenic SIV infections and exhibit higher rates of postnatal virus transmission. In this study, of acute SIV infection, we compared the initial systemic Env-specific B cell responses of AGMs and RMs in order to probe potential factors influencing the lack of disease progression observed in AGMs. AGMs developed higher-magnitude plasma gp120-specific IgA and IgG responses than RMs, whereas RMs developed more robust gp140-directed IgG responses. These gp120-focused antibody responses were accompanied by rapid autologous neutralizing responses during acute SIV infection in AGMs compared to RMs. Moreover, acute SIV infection elicited a higher number of circulating Env-specific memory B cells in peripheral blood of AGMs than in the blood of RMs. These findings indicate that AGMs have initial systemic Env-specific B cell responses to SIV infection distinct from those of a nonnatural SIV host, resulting in more functional SIV-specific humoral responses, which may be involved in impairing pathogenic disease progression and minimizing postnatal transmission. IMPORTANCE Due to the worldwide prevalence of HIV-1 infections, development of a vaccine to prevent infection or limit the viral reservoir

    2012-12-01

    Extreme hydrologic events in the form of droughts are a significant source of social and economic damage. 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).

    Friedrich, Elena; Trois, Cristina

    2013-11-01

    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.

    ABSTRACT African horse sickness virus (AHSV) is a virus species in the genus Orbivirus of the family Reoviridae. There are nine serotypes of AHSV showing different levels of cross neutralization. AHSV is transmitted by species of Culicoides biting midges and causes African horse sickness (AHS) in equids, with a mortality rate of up to 95% in naive horses. AHS has become a serious threat for countries outside Africa, since endemic Culicoides species in moderate climates appear to be competent vectors for the related bluetongue virus (BTV). To control AHS, live-attenuated vaccines (LAVs) are used in Africa. We used reverse genetics to generate “synthetic” reassortants of AHSV for all nine serotypes by exchange of genome segment 2 (Seg-2). This segment encodes VP2, which is the serotype-determining protein and the dominant target for neutralizing antibodies. Single Seg-2 AHSV reassortants showed similar cytopathogenic effects in mammalian cells but displayed different growth kinetics. Reverse genetics for AHSV was also used to study Seg-10 expressing NS3/NS3a proteins. We demonstrated that NS3/NS3a proteins are not essential for AHSV replication in vitro. NS3/NS3a of AHSV is, however, involved in the cytopathogenic effect in mammalian cells and is very important for virus release from cultured insect cells in particular. Similar to the concept of the bluetongue disabled infectious single animal (BT DISA) vaccine platform, an AHS DISA vaccine platform lacking NS3/NS3a expression was developed. Using exchange of genome segment 2 encoding VP2 protein (Seg-2[VP2]), we will be able to develop AHS DISA vaccine candidates for all current AHSV serotypes. IMPORTANCE African horse sickness virus is transmitted by species of Culicoides biting midges and causes African horse sickness in equids, with a mortality rate of up to 95% in naive horses. African horse sickness has become a serious threat for countries outside Africa, since endemic Culicoides species in moderate

    Although researchers have identified beneficial coping strategies for cancer patients, existing coping measures do not capture the preferred coping strategies of older African American cancer survivors. A new measure, the Ways of Helping Questionnaire (WHQ), was evaluated with 385 African American cancer survivors. Validity evidence from factor analysis resulted in 10 WHQ subscales (Others There for Me, Physical and Treatment Care Needs, Help from God, Church Family Support, Helping Others, Being Strong for Others, Encouraging My Healthy Behaviors, Others Distract Me, Learning about Cancer, and Distracting Myself). Reliability evidence was generally strong. Evidence regarding hypothesized relationships with measures of well-being and another coping measure was mixed. The WHQ's content coverage makes it especially relevant for older African American cancer survivors. PMID:19259991

    High-density single nucleotide polymorphism (SNP) genotyping arrays are powerful tools that can measure the level of genetic polymorphism within a population. To develop a whole-genome SNP array for oil palms, SNP discovery was performed using deep resequencing of eight libraries derived from 132 Elaeis guineensis and Elaeis oleifera palms belonging to 59 origins, resulting in the discovery of >3 million putative SNPs. After SNP filtering, the Illumina OP200K custom array was built with 170 860 successful probes. Phenetic clustering analysis revealed that the array could distinguish between palms of different origins in a way consistent with pedigree records. Genome-wide linkage disequilibrium declined more slowly for the commercial populations (ranging from 120 kb at r(2) = 0.43 to 146 kb at r(2) = 0.50) when compared with the semi-wild populations (19.5 kb at r(2) = 0.22). Genetic fixation mapping comparing the semi-wild and commercial population identified 321 selective sweeps. A genome-wide association study (GWAS) detected a significant peak on chromosome 2 associated with the polygenic component of the shell thickness trait (based on the trait shell-to-fruit; S/F %) in tenera palms. Testing of a genomic selection model on the same trait resulted in good prediction accuracy (r = 0.65) with 42% of the S/F % variation explained. The first high-density SNP genotyping array for oil palm has been developed and shown to be robust for use in genetic studies and with potential for developing early trait prediction to shorten the oil palm breeding cycle.

    Highlights: • GHG emission factors for local recycling of municipal waste are presented. • GHG emission factors for two composting technologies for garden waste are included. • Local GHG emission factors were compared to international ones and discussed. • Uncertainties and limitations are presented and areas for new research highlighted. - Abstract: 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 prehistory of African trypanosomiasis indicates that the disease may have been an important selective factor in the evolution of hominids. Ancient history and medieval history reveal that African trypanosomiasis affected the lives of people living in sub-Saharan African at all times. Modern history of African trypanosomiasis revolves around the identification of the causative agents and the mode of transmission of the infection, and the development of drugs for treatment and methods for control of the disease. From the recent history of sleeping sickness we can learn that the disease can be controlled but probably not be eradicated. Current history of human African trypanosomiasis has shown that the production of anti-sleeping sickness drugs is not always guaranteed, and therefore, new, better and cheaper drugs are urgently required.

    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. )

    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

    The preservation of germ plasm from endangered species could augment captive breeding programs aimed at maintaining genetic diversity. Mammalian female germ plasm (oocytes) is extremely difficult to collect and cryopreserve; however, a promising alternative is the cryopreservation of ovarian tissue. In the present study, athymic nude (nu/nu) Balb/C mice were used to evaluate in vivo viability of cryopreserved ovarian tissue from Institute of Cancer Research genotype (ICR) mice or elephants. Female mice were ovariectomized prior to transplant of cryopreserved-thawed ovarian tissue from ICR mice (n=4) or elephants (n=6). Control mice were sham operated (n=4) or ovariectomized (n=5). Transplants were in the ovarian bursa, enabling in vivo ovulation and pregnancies from allografts. Vaginal cytology was monitored daily, and the intervals between and duration of epithelial cells present in smears were evaluated. Appearance of epithelial cells in sham-operated and allografted mice were at intervals of 4.3+/-0.6 and 3.3+/-0.5 days, lasting for 1.4+/-0.1 and 1.6+/-0.2 days, respectively. Sporadic incidence of epithelial cells in ovariectomized animals occurred at longer intervals (8.6+/-3.8 days). Females with xenografted elephant ovarian tissue demonstrated epithelial cells in vaginal smears at intervals of 4.5+/-1.0 days, for 2.5+/-0.5 days duration, which was significantly longer than the other groups (P < 0.05). Histological evaluation of tissues at the time of epithelial cells in smears demonstrated well-developed antral follicles, although oocytes were of poor morphological appearance or only cumulus-like complexes were seen. The nude mouse model is effective for assessing cryopreserved ovarian tissue xenograft function which can support the development of antral follicles.

    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. PMID:19069993

    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

  16. Designing Agricultural Development Projects for the Small Scale Farmers: Some Lessons from the World Bank Assistance Small Holder Oil Palm Development Scheme in Nigeria

    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.

    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

    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

    Hormonal analysis provides information about wildlife populations, but is difficult to conduct in the field. Our goal was to develop a rapid and effective field method for fecal steroid analysis by comparing: (1) three extraction methods (laboratory (LAB), homogenize (HO) and handshake (HS)) and (2) two storage methods (solid-phase extraction (SPE) tubes vs. plastic tubes (PT)). Samples (n=23) from captive African wild dogs (Lycaon pictus) were thoroughly mixed, three aliquots of each were weighed ( approximately 0.5 g) and 5 ml of 90% ethanol was added. For LAB, samples were agitated (mixer setting 60; 30 min), centrifuged (1,500 rpm; 20 min) and poured into glass tubes. Or aliquots were HO (1 min) or HS (1 min) and poured through filter paper into glass tubes. Samples were split, analyzed for corticosterone (C) and testosterone (T) metabolites using enzyme immunoassays or stored in SPE or PT. Samples were stored (room temperature) for 30, 60 or 180 days, reconstituted in buffer and analyzed. Mean C and T recoveries of HO were greater (P=0.03) than HS compared with LAB, which was similar to HO (P>0.05). After 30 days <21% of C and T was recovered from SPE, but approximately 100% of each was recovered from HO-PT and HS-PT. Similarly, after 60 and 180 days, approximately 100% of C and T was recovered from HO-PT and HS-PT. Results demonstrated that, for C and T, HO was more comparable (P<0.001) to LAB than HS and PT storage was more efficient than SPE (P<0.001).

    A meningococcal group A polysaccharide (PS) conjugate vaccine (PsA-TT) has been developed for African countries affected by epidemic meningitis caused by Neisseria meningitidis. Complement-mediated serum bactericidal antibody (SBA) assays are used to assess protective immune responses to meningococcal vaccination. Human complement (hC′) was used in early studies demonstrating antibody-mediated protection against disease, but it is difficult to obtain and standardize. We developed and evaluated a method for sourcing hC′ and then used the SBA assay with hC′ (hSBA) to measure bactericidal responses to PsA-TT vaccination in 12- to 23-month-old African children. Sera with active complement from 100 unvaccinated blood donors were tested for intrinsic bactericidal activity, SBA titer using rabbit complement (rSBA), and anti-group A PS antibody concentration. Performance criteria and pooling strategies were examined and then verified by comparisons of three independently prepared hC′ lots in two laboratories. hSBA titers of clinical trial sera were then determined using this complement sourcing method. Two different functional antibody tests were necessary for screening hC′. hSBA titers determined using three independent lots of pooled hC′ were within expected assay variation among lots and between laboratories. In African toddlers, PsA-TT elicited higher hSBA titers than meningococcal polysaccharide or Hib vaccines. PsA-TT immunization or PS challenge of PsA-TT-primed subjects resulted in vigorous hSBA memory responses, and titers persisted in boosted groups for over a year. Quantifying SBA using pooled hC′ is feasible and showed that PsA-TT was highly immunogenic in African toddlers. PMID:24671551

    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.

    The potential impact of atrazine (ATZ) on gonadal malformations in larval Xenopus laevis has been controversially discussed, and a hypothesis has been generated that ATZ might induce the estrogen-synthesizing enzyme aromatase, leading to feminization or demasculinization. Recently, extensive long-term studies clearly indicate that no adverse effect of ATZ on larval development and sexual differentiation could be found. Therefore, to determine potential transient impacts of ATZ on sexual differentiation processes, short-term exposures were conducted using tadpoles treated for 4 days with ATZ at 25 microg/L. The expression levels of the key players for sexual differentiation in amphibians were determined in the brain, assessing aromatase, 5alpha-reductase type 1 (S1) and type 2 (S2), and the gonadotropins luteinizing hormone and follicle-stimulating hormone, and in the gonads, measuring aromatase, S1, and S2, by means of quantitative RT-PCR. No significant changes in any of these parameters have been found, implicating, in accordance with recent long-term exposures, that no aromatase induction by ATZ could be observed, and it seems likely that no further endocrine mechanism of ATZ affecting sexual differentiation in X. laevis exists.

    During the years 2009-2012, faeces of African penguins (Spheniscus demersus L.) from South African rehabilitation centres were examined for helminths. In total, 46 out 555 samples (8.29 %), mostly belonging to adult birds, were found to contain oval schistosome eggs with a spine on one pole. Their dimensions were 153.21 ± 9.07 × 87.14 ± 8.67 μm. Selected DNA fragments (18S, 28S and ITS rDNA) were sequenced and compared to other schistosome isolates deposited in GenBank. The shape of the eggs suggests that they belong to the genus Gigantobilharzia; however, due to the insufficient stage of knowledge of the genus and limited number of species available for comparison, we were not able to assign the isolate unambiguously to this genus based on either the egg morphology or the results of molecular analysis.

    The Patient Reported Outcomes Measurement Information System (PROMIS) initiative aims to provide reliable and precise item banks measuring patient-reported outcomes in different health domains. The aim of the present work was to provide a German translation of the PROMIS item banks for satisfaction with participation and to psychometrically test these German versions. Cognitive interviews followed a forward-backward translation. Distribution characteristics, unidimensionality, Rasch model fit, reliability, construct validity, and internal responsiveness were tested in 262 patients with chronic low back pain undergoing rehabilitation. Results for the final 13- and 10-item German static scales (Satisfaction with Participation in Social Roles-German version [PSR-G] and Satisfaction for Participation in Discretionary Social Activities-German version [PSA-G]) regarding unidimensionality were satisfactory. The scales are reliable and show good Rasch model fit and distribution characteristics. Both scales are sensitive to small to moderate clinical changes, and we observed initial proof of construct validity. These German versions of the Satisfaction with Participation scales can be recommended to assess participation in a clinical context. The scales' applicability in other contexts should be examined.

    Oral habituation is a relatively long-lasting decrease in oral responsiveness that results from the repeated presentation of a single stimulus. The purpose of this study was to evaluate the degree of habituation to sweet-tasting foods and to determine whether there are differences in the rate of habituation between African Americans and European Americans. These two groups were compared because the prevalence of obesity and obesity-related disorders such as diabetes and hypertension is significantly higher among African Americans than among European Americans. Nine different commercial foods and beverages that differed in sweetness intensity and caloric density served as stimuli. Subjects tasted and rated each food once per minute for a 30-min period on scales related to desire for another taste of the same sample and desire for a different taste. The stimuli and portion size for each of the 30 samples were two candy bars (Ultra Slim-Fast Cocoa Almond Crunch Bar, 1/16 of a bar; Natural Nectar Peanut Butter Granola Bar, 1/16 of a bar), three beverages (Nestea Lemon Flavored Instant Tea with NutraSweet, 5 mL; Welch's Grape Juice, 5 mL; Pink Swimmingo Kool-Aid, 5 mL), two gelatin desserts (Cherry Flavored Jell-O Gelatin, 5 g; Cherry Flavored Jell-O Gelatin with NutraSweet, 5 g), one enteral nutrition drink (Vanilla Ensure Plus, 5 mL), and one pudding (Ultra Slim-Fast Chocolate Pudding, 5 g). Subjects consumed the entire portion of each sample. Habituation occurred for seven of the nine foods as judged by a decrease in the desire for another taste of the same food. The degree of habituation for European Americans and African Americans was similar except for the sweetest food (Cherry Flavored Jell-O Gelatin with NutraSweet), for which African Americans showed no habituation. The degree of habituation in both groups was unrelated to caloric density. Overall, young African Americans had a significantly greater desire for another taste of the same food than did young

    Heads of state of Africa signed a pledge to reduce the continent's malaria mortality by 50% by 2110 at an international summit of Malaria in Abuja, Nigeria. The primary focus of the malaria control program will be insecticide-treated bednets. The WHO wants a 30-fold increase in the availability of bednets in the next 5 years, as well as immediate access to cheap and effective antimalarial combination therapy for families at risk of malaria, including pregnant women. Malaria control requires annual donations of US$1 billion from industrialized countries. However, donations alone will be insufficient unless there is immediate debt cancellation, says Jeffrey Sachs, director of the Center for International Development at Harvard. The World Bank also raised criticisms concerning the US$150 million annual donation. In response, Ok Pannenborg of the World Bank stated that there are 100 World Bank operations all over Africa and its US$150 million annual donation for African malarial control projects is money they can use, but whether they use it is another matter.

    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.

    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 main capacitor bank for the Nova laser system at Lawrence Livermore National Laboratory was found to be seismically unsafe after the 1989 Loma Prieta earthquake. A method of strengthening the bank was developed, which satisfied the current seismic design criteria and minimized the downtime of the laser system during installation. Before implementation, the design was analyzed by finite element methods and the building was checked for load capacity. The bank is now upgraded to current seismic standards.

    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.

  11. 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

    Two thousand nine hundred kilometers of minisparker data were collected on Georges Bank by the United States Geological Survey during October of 1975. Several sedimentary features have been observed in the data, The bank is recognized as a compound feature resulting from erosion of Tertiary coastal-plain strata followed by deposition of an extensive sediment wedge on the western flank of the cuesta. Marine planation (probably Late Pleistocene) truncated this bank morphology producing an erosion surface roughly paralleling the present sea floor. The truncated bank surface is blanketed by a veneer of complex Late Pleistocene drift which masks underlying features and is being reworked by modern processes. Present bank morphology is inferred-to be arather recent development. A proper understanding of the significance of complex bank sediments with respect to the potential geologic hazards of drilling or placement of bottom. supported structures necessitates a more detailed seismic reflection program, in conjunction with geotechnical analysis of core-samples.

  14. Stream Bank Stability in Eastern Nebraska

    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

    During the 1970s it was World Bank policy to use its funds to raise the productivity and living standards of the poor. It has increased its lending for sector and subsectors considered to offer the most direct benefits to the poor such as rural development, population, health, and nutrition. Projects with particular emphasis on poverty have benefitted large numbers of poor people and have had good economic rates of return. Lending for rural projects increased in the 1970s from US$2.6 billion in 1969-73 to over US$13 billion in 1978-81; rural development projects audited in 1979 benfitted 660 small farmers for every US$1 million loaned compared with 47 farmers/US$1 million in other agricultural projects. Some problems are: 1) low-risk technical packages appropriate for poor farmers in semi-arid rainfed areas are not readily available; 2) the Bank's rural development strategy seeks mainly to raise the production of small farms, but other aspects need to be emphasized; 3) domestic pricing and postharvest policies often undermine the success of projects aimed at the rural poor; and 4) success in rural development often rests on sociological and cultural factors, difficult areas that deserve more attention. For urban areas the Bank has strongly endorsed providing "sites and sources" instead of structures; since 1972, 52 Bank projects centered on urban shelter involving US$1.6 billion have been undertaken. Cost recovery is established at 66-95%. About 5% of Bank lending is for education and despite the importance of population, health, and nutrition, these areas absorb less than 1% of the Bank's total lending program. Only US$400 million in population loans were made to 13 countries in the 1970s and only recently have separate health projects been started. Emphasis for the 1980s must be on rural development, urban shelter, primary education, health, education, and population. PMID:12338639

    In this project, we are developing and exploiting a unique seismic data set to address the characteristics of small seismic events and the associated seismic signals observed at local (< 200 km) and regional (< 2000 km) distances. The dataset is being developed using mining-induced events from 3 deep gold mines in South Africa recorded on inmine networks (< 1 km) comprised of tens of high-frequency sensors, a network of 4 broadband stations installed as part of this project at the surface around the mines (1-10 km), and a network of existing broadband seismic stations at local/regional distances (50-1000 km) from the mines. After 1 year of seismic monitoring of mine activity (2007), over 10,000 events in the range -3.4 < ML < 4.4 have been catalogued and recorded by the in-mine networks. Events with positive magnitudes are generally well recorded by the surface-mine stations, while magnitudes 3.0 and larger are seen at regional distances (up to {approx}600 km) in high-pass filtered recordings. We have analyzed in-mine recordings in detail at one of the South African mines (Savuka) to (i) improve on reported hypocentral locations, (ii) verify sensor orientations, and (iii) determine full moment tensor solutions. Hypocentral relocations on all catalogued events have been obtained from P- and S-wave travel-times reported by the mine network operator through an automated procedure that selects travel-times falling on Wadati lines with slopes in the 0.6-0.7 range; sensor orientations have been verified and, when possible, corrected by correlating P-, SV-, and SH-waveforms obtained from theoretical and empirical (polarization filter) rotation angles; full moment tensor solutions have been obtained by inverting P-, SV-, and SH- spectral amplitudes measured on the theoretically rotated waveforms with visually assigned polarities. The relocation procedure has revealed that origin times often necessitate a negative correction of a few tenths of second and that hypocentral

    Health inequalities exist throughout the African Diaspora and are viewed in this article as largely color-coded. In developed, developing, and undeveloped nations today, "racial" stratification is consistently reflected in an inability to provide adequate health regardless of national policy or ideology. For instance, African Americans experience less than adequate health care very similar to Blacks in Britain, in spite of each nations differing health systems. Latin America's Africana Negra communities experience poorer health similar to Blacks throughout the Caribbean. The African continent itself is arguably the poorest on earth. A common history of racism correlates with health disparities across the African Diaspora.

    Modern nuclear data Quality Assurance (QA) is, in practice, a multistage process that aims at establishing a thorough assessment of the validity of the physical information contained in an evaluated nuclear data file as compared to our best knowledge of available experimental data and theoretical models. It should systematically address the performance of the evaluated file against available pertinent integral experiments, with proper and prior verification that the information encoded in the evaluation is accurately processed and reconstructed for the application conditions. The aim of the NDEC (Nuclear Data Evaluation Cycle) platform currently being developed by the Data Bank is to provide a correct and automated handling of these diverse QA steps in order to facilitate the expert human assessment of evaluated nuclear data files, both by the evaluators and by the end users of nuclear data.
