Abstract:
Soybean rust, caused by the biotrophic pathogen Phakopsora pachyrhizi, is a highly destructive disease causing substantial yield losses in many soybean producing regions throughout the world. Knowledge about P. pachyrhizi virulence is needed to guide development and deployment of soybean germplasm with durable resistance against all pathogen populations. To assess the virulence diversity of P. pachyrhizi, 25 isolates from eight countries, including 17 isolates from Africa, were characterized on 11 soybean genotypes serving as differentials. All the isolates induced tan lesions with abundant sporulation on genotypes without any known resistance genes and on soybean genotypes with resistance genes Rpp4 and Rpp5b. The most durable gene was Rpp2, where 96% of the isolates induced reddish brown lesions with little or no sporulation. Of the African isolates tested, the South African isolate was the most virulent, whereas those from Kenya, Malawi, and some of the isolates from Tanzania had the lowest virulence. An Argentinian isolate was virulent on most host differentials, including two cultivars carrying multiple resistance genes. Ten distinct pathotypes were identified, four of which comprised the African isolates representing considerable P. pachyrhizi virulence. Soybean genotypes carrying Rpp1b, Rpp2, Rpp3, and Rpp5 resistance genes and cultivars Hyuuga and UG5 were observed to be resistant against most of the African isolates and therefore may be useful for soybean-breeding programs in Africa or elsewhere.

Abstract:
The following bibliography is intended to supplement the excellent one (largely) of secondary sources compiled by Thomas Spear and published inHistory in Africa27(2000). Research for a forthcoming monograph on the East African coast in the ‘middle’ period has taken me in recent years into a number of libraries and archives in India, East Africa, and Europe. There I have been able to build an extensive listing of source material and oral informants interviewed in East Africa. While this compilation includes many of the titles in Spear's list, study carried out in Goa and Lisbon afforded me the opportunity of viewing primary sources not included in Spear's collection. Despite the fact that this is still a work in progress, I submit this supplementary list hoping it might prove useful to other scholars interested in East Africa and the western Indian in the pre- and early-modern period.Readers also will note that I have included some secondary listings not included in Spear's bibliography. This is due to the fact that my ideas concerning what is relevant to coastal history appear to be somewhat broader than Spear's. Consequently, this list includes some titles on southern and central Africa, as well as of coastal literature, which I have found to be useful and apposite to coastal studies. Naturally, I have tried not to duplicate titles found in Spear's list.

Abstract:
Understanding the genetic structure and diversity of crops facilitates progress in plant breeding. A collection of 270 bambara groundnut (Vigna subterrenea L) landraces sourced from different geographical regions (Nigeria/Cameroon, West, Central, Southern and East Africa) and unknown origin (sourced from United Kingdom) was used to assess genetic diversity, relationship and population structure using DArT SNP markers. The major allele frequency ranged from 0.57 for unknown origin to 0.91 for West Africa region. The total gene diversity (0.482) and Shannon diversity index (0.787) was higher in West African accessions. The genetic distance between pairs of regions varied from 0.002 to 0.028 with higher similarity between Nigeria/Cameroon-West Africa accessions and East-Southern Africa accessions. The analysis of molecular variance (AMOVA) revealed 89% of genetic variation within population, 8% among regions and 3% among population. The genetic relatedness among the collections was evaluated using neighbor joining tree analysis, which grouped all the geographic regions into three major clusters. Three major subgroups of bambara groundnut were identified using the ADMIXTURE model program and confirmed by discriminant analysis of principal components (DAPC). These subgroups were West Africa, Nigeria/Cameroon and unknown origin that gave rise to sub-population one, and Central Africa was sub-population two, while Southern and East Africa were sub-population three. In general, the results of all the different analytical methods used in this study confirmed the existence of high level of diversity among the germplasm used in this study that might be utilized for future genetic improvement of bambara groundnut. The finding also provides new insight on the population structure of African bambara groundnut germplasm which will help in conservation strategy and management of the crop.

Abstract:
Abstract There is an increasing global demand for existing natural history information for use in education, conservation, and policy formulation. Museum specimen collection records, being voluminous, are particularly significant in addressing such demands. This is even more critical in developing countries where daily human life is intimately linked to the environment. We demonstrate how existing museum specimen collection records were mobilized to highlight important animal pollinators in three East African countries. The bulk of the records were obtained from a Specify database of existing zoological collections held at the National Museums of Kenya, and the rest were from such alternative sources as published material, discussions with pollination experts, and online taxonomic portals and other tools. Identified to genus or species level, pollinator-ranking criteria encompassed region-wide distribution, number of plants pollinated, importance index of plants pollinated, and plant dependency on pollination. Overall, insects, especially Apis mellifera, were the most important pollinators in the region, pollinating the largest number of plants of diverse domestic, socioeconomic, and ecological significance. The results underscore potential use of specimen record-based informatics to guide agricultural and economic policy in East Africa.

Abstract:
Sets of microsatellites extracted from both a genomic library (gSSRs) and from expressed sequence tag sequence (eSSRs), and single nucleotide polymorphisms (SNPs) were applied to assess the levels of genetic diversity in a sample of 70 barley accessions, originating from 28 countries in Asia, Africa, the Middle East and Europe. The eSSR assays detected a mean of 9.5 alleles per locus, and the gSSRs only 5.7 alleles per locus, but the polymorphism information content values for the two assay types were indistinguishable. Strong and statistically significant correlations were observed between the eSSR and gSSR (r = 0.86,P < 0.05), the eSSR and SNP (r = 0.74,P < 0.05) and the gSSR and SNP genotypes (r = 0.67,P < 0.05). Accessions originating from the Middle East and Asia had the highest levels of genetic diversity. Pairwise genetic similarity ranged from 0.16 to 0.87 (mean 0.43), indicating that the sample was genetically diverse. When clustered on the basis of genotype, Asian and African accessions tended to be grouped together, but those originating from the Middle East were not concentrated in any particular cluster.

Abstract:
History<br>Ph.D.<br>The dissertation explores the intellectual history of the interconnection of European and African ideas about race and space in 19th-century European imperialism. I examine German colonial geographies of East Africa, meaning not only cartography, but the new discipline of human geography, which studies the relationship between people and their environment. Germans and East Africans together produced a hybrid geography that combined precolonial conceptions of race and space and race from both Europe and Africa, and race explicitly entered German governance for the first time. By analyzing changes in how both Germans and East Africans imagined geographical relationships, I argue, we can better understand the ways in which they developed new conceptions of themselves and the world at the end of the 19th and beginning of the 20th centuries. The project traces the history of German racial thinking to a specific, earlier colonial context than other scholars have argued. It also brings a spatial dimension to studies of the colonial state in Africa in order to understand the ways in which spaces have become imbued with racial and ethnic meaning over the last century and a half.<br>Temple University--Theses

This study analyzed the revolutions in Tunisia, Egypt, and Libya (North Africa) beginning in late 2010. The first part of the study focused on variables that the North African revolutions shared. These variables were “personalistic-style of dictatorship”, “sizable percentage of youth in population”, and “economic context”. These factors were then discussed as major descriptive variables that caused the revolutionary events in North Africa. The second part of the study assessed why each North African revolution resulted in varying levels of violence. Concluding thoughts were made regarding the similarities and differences between the 2009 Iranian Green Revolution, events in other North African Arab-majority states such as Algeria and Morocco, and the on-going Syrian Revolution to the North African Revolutions<br>M.A.<br>Masters<br>Political Science<br>Sciences<br>Political Science; International Studies

Abstract:
The purpose of this research was to determine the effectiveness of a character education program on middle school student academic performance, effort and attitude about their school located in an international setting. Middle school students at the participating international school were assigned to either an experimental or control group. Those students in the experimental group classes received a series of 12 lessons focusing on the character trait of responsibility. Those students in the control group classes did not receive these lessons. Twelve responsibility-based lessons were presented to students in the experimental group. Student academic grades in six different academic subjects, effort scores in six different academic courses, and student attitude concerning school climate constituted the dependent variable. The literature review and the general results of this study indicate that there are many factors that may influence student academic performance, effort or attitude. Various character education programs which have been designed to be integrated into school curricula as part of pre-existing courses or as stand alone programs have had varying levels of success. There is limited quantitative data available to support the claims that many existing programs make related to their effectiveness. The data collected from this study were also inconclusive making it difficult to generalize the findings beyond the scope of this study. While certain middle school grade levels showed statistically significant improvement in some academic disciplines or effort improvement in some subjects it would not be appropriate to generalize the findings based on this investigation. Implications of this study and suggestions for future investigations are discussed.<br>Ph.D.<br>Department of Child, Family and Community Sciences<br>Education<br>Education: Ph.D.

Abstract:
This study investigated the use and effectiveness of the East Africana Collection in the provision of information and resource for teaching and research at the University of Dar es Salaam, Tanzania. The East Africana Collection is mainly used as a source of obtaining information by students, lecturers and researchers in and off campus. The Collection's goal is to meet user needs and make available valuable materials and services for the purpose of supporting the learning, teaching and research needs of the University of Dar es Salaam community. Special collections in academic libraries especially in the so-called Third World countries have been suffering from financial constraints. The reduced government budget and the economic problems, have forced some special collections to operate ineffectively without any new incoming materials to supplement the old ones. The East Africana Collection of the University of Dar es Salaam Library which operates as a defacto national research collection in the country has also been affected by the government budget cut. In order to find out the use and effectiveness of the East Africana Collection in the provision of information and resource for teaching and research at the University of Dar es Salaam, Tanzania, a study sample consisting of 52 teaching and research staff was chosen from four faculties and three Institutes of the University of Dar es Salaam. The teaching and research staff was surveyed by means of a self-administered questionnaire to investigate the user satisfaction, availability of materials, resources and effectiveness of the services to cater for the information needs of users. Other information requested from respondents related to the East Africana services was library staff services and what problems teaching and research staff encountered when using the Collection's materials and services. A total of36 teaching and research staff (representing 64.9%) responded. The results were analysed manually. Content analysis was used to analyse open ended questions. The results were shown in the form of tables and elaborations. The study revealed that East Africana Collection had experienced heavy use of its materials, services and resources by both students, teachers and researchers within the University community and outside the campus. It is an indication that Collection usage among teaching and research staff was generally very high. However, the Collection faces the problem of lack of sufficient facilities and resources. Whatever the problems users experienced, the majority of the teaching and research staff were aware of the East Africana Collection and its information materials and services. Recommendations and suggestions for the future betterment of the services were made by both researcher and respondents with regard to the findings of the study and the literature reviewed.<br>Thesis (M.I.S.)-University of Natal, Pietermaritzburg, 2000.

Abstract:
This research investigated the management of audiovisual materials (AV) in the East and Southern Africa Regional Branch of the International Council on Archives (ESARBICA). The study employed questionnaires, interviews and observation to gather data from a population of fourteen national archives. The response rate from the questionnaires was 64.28%. The observations and interviews were carried out from a sample of three national archives and four national media organisations, as explained in Chapter Three. The study confirmed previous studies that attributed continued dissipation of AV materials to various factors such as climatic and environmental conditions, shortage or lack of skilled AV archivists and lack of a standard legal framework in the ESARBICA region. Most national archives did not cover audiovisual archives in their legislation. The study discovered that most of the national archives did not apply the following policies to AV materials: appraisal, acquisition, access, preservation, retention, digitisation and disposal. The study revealed that most of the national archives had a collaborative relationship with national media organisations, where the latter were required to deposit copies of AV materials in the national archives. However, some national archives relegated the responsibility of managing AV materials to media organisations. Poor infrastructure hindered effective management of AV materials. Most of the national archives did not have equipment to monitor environmental conditions. This could have contributed to the vinegar syndrome in some of the national archives. Poor structural placement of some of the national archives resulted in inadequate allocation of funds to the national archives. This invariably impacted on the way national archives preserved AV materials. The researcher discovered that there were very few training opportunities in AV archiving in the region. The few trained staff had intermediate skills obtained from conferences, seminars and workshops. Most importantly, the study revealed that most of the national archival institutions in the region were not applying the records life-cycle model (or any other model) to the management of AV materials. The major recommendations were a change in the structural placement of the national archives, where the directors of the archives would report to an influential ministry in the government service. Such a position would accord the national archives more recognition and thus more financial resources may be availed to the national archives to enable them manage the nation's heritage more effectively. An Integrated Records Management (IRM) model was recommended. The application of the IRM model requires a paradigm shift from the traditional image of archivists as mere custodians of archives to active participants in the decisions that affect the management of all formats of records, from the creators' organisations or departments before such records (including AV materials) are transferred to the national archives for long-term preservation.<br>Thesis (Ph.D.)-University of KwaZulu-Natal, Pietermaritzburg, 2008.

Abstract This essay collection is the outcome of interdisciplinary research into political, societal, and cultural transformation processes in the Middle East and North Africa (MENA) region at the Philipps-Universität in Marburg, Germany. It builds on many years of collaboration between two research networks at the Center for Near and Middle Eastern Studies: the research network “Re-Configurations: History, Remembrance and Transformation Processes in the Middle East and North Africa” (2013–19), funded by the German Federal Ministry of Education and Research (BMBF), and the Leibniz-Prize research group “Figures of Thought | Turning Points: Cultural Practices and Social Change in the Arab World” (2013–20), funded by the Deutsche Forschungsgemeinschaft (DFG). Both research projects’ central interest lay in the political, social, and cultural transformation that has become especially visible since 2010–11; we conceptualize this transformation here using the term “re-configurations.” At the core of the inquiry are interpretations of visions of past and future, power relations and both political and symbolic representations.

Abstract:
Ribot, Morris, and Renschler compare two distinct case studies of Africans in order to investigate identity, origin, and population affinity of diasporic populations. In the first case study from Cobern Street in Cape Town, South Africa, the authors integrate stable isotope data and burial data with craniometric variation. In the second case, craniometric data are studied in a sample of Africans from the Morton Collection derived from a group of enslaved people brought to Colonial Cuba. In the Cobern Street setting, they find evidence of both first and second-generation immigrants or imported slaves from sub-Saharan Africa, as well as the possible presence of people of Asian descent (either slaves or immigrants). In contrast with the Cobern Street case study, Ribot and colleagues find high levels of diversity represented in the Morton sample, with some individuals from a single origin within Central, West, or East Africa, some individuals exhibiting multiple possible African origins, and finally, some other individuals exhibiting complex patterns of heterogeneity which may reflect origins and admixture from Asia, Europe, or Mesoamerica.

Abstract:
Charles Burdett addresses the representation of the Italian presence in East Africa in the decades following the Second World War, the demise of Fascism and the end of Italian colonialism. The chapter looks in depth at the publications of the former Italian residents of Eritrea and Ethiopia, written memories of life in Africa, commentaries on current events, works of fiction and an extensive collection of photographs. Rather than as straightforward narrations or as transparent reproductions of people’s experiences, these materials are seen as complex evocations of multifaceted psychic realities, intimately bound up with unseen temporal processes. This cultural production is seen as a means of discovering how the past can return to trouble the present and reveal the individual’s unknowing participation in some of the most deeply layered practices of society.

Abstract:
Many Aspects of Different Cultures can help to throw light on their differing identities—language, architecture, religion, and many other things, such as the ‘range of landscapes, ways of thought, racial groups, roof-tops and cheeses’. In fact, almost anything. A particular category is provided by the institutions people observe, a category which might embrace an enormous range of different things, from burial practices to legal systems, or from different calendars to different systems of weights and measures. The link between coins, weights, and measures was clear to the Greeks and Romans, and that coins could be regarded as an expression of some at least of the values characteristic of a particular society is evident from an anecdote reported by Pliny as taking place in the reign of Claudius. He relates how a Roman was forced by a storm to Sri Lanka (ancient Taprobane), and how he told the local king about Rome: A freedman of Annius Plocamus, who had brought the tax collection for the Red Sea from the Treasury, was sailing round Arabia. He was carried along by winds from the north past Carmania and, on the fifteenth day, made harbour at Hippuros in the island; and in consequence of the kind hospitality of the king he learned the local language thoroughly over a period of six months, and afterwards in reply to his questions described the Romans and Caesar. In what he heard the king got a remarkably good idea of their honesty, because among the captured money there were denarii which were of equal weight, even though their various types indicated that they were issued by several persons. I want to apply this approach to the Roman world, and use coins in a way that may throw light on some of the ways that Romans regarded themselves, having a special look at the differences between the western and eastern parts of the empire. I want to suggest that we can use this sort of approach to help explain the fundamental change that took place in the currency of the Iberian peninsula, Gaul, Italy, Sicily, and Africa in the first century AD—how people there stopped using locally made coins and started to use coins imported from Rome, coins which might otherwise have been regarded in some sense as almost ‘foreign’.

Abstract:
For over a thousand years, the Swahili culture of coastal East Africa had developed by synthesising myriad influences from the African continent, Arabia and across the Indian Ocean. By the mid-Victorian period Zanzibar was a key Indian Ocean commercial centre, and in 1890 was established as a British Protectorate. This chapter examines, through writings, collections of material culture and photographs, the British encounter with Zanzibar and the island’s cosmopolitan culture. British officers described themselves as going to ‘the East’ when departing for the island. The word itself epitomised mysterious otherness and exoticism, while its Arabian-Nights charm contrasted with the stereotypes about the African interior. Yet its skyline was criticised for lacking minarets and domes and being insufficiently Islamic. It was also described as unhealthy and dirty, making British intervention necessary to transform it into ‘an island paradise’. This chapter analyses how the British response to Zanzibar as a liminal space between Africa and the East shifted in this period of economic and political transformation on the coast.

Abstract:
Two related phenomena characterize the last 30,000 years or so of the Pleistocene and the Old Stone Age in Europe, a period known as the Upper Paleolithic. The first of these is the arrival of a version of ourselves, Homo sapiens, around 40,000 years ago. The second is the creative explosion in technology, equipment, raw materials, art, and decoration that took place in this period. There appears to have been a substantial upgrade in human abilities and the variety of activities taking place. The first part of this chapter examines some of the sites and places that tell this story. At the end of the Pleistocene and the Paleolithic, 10,000 years ago, hunter-gatherers continued to thrive in a warmer, “postglacial” Europe, but their time was coming to an end. Agriculture had been invented in the Near East and was spreading toward the continent, arriving in the southeast by 7000 BC and reaching the northeast by 4000 BC. This period of post-Pleistocene hunter-gatherers in Europe is known as the Mesolithic and is the focus of the second part of this chapter. By the end of the Pleistocene, Homo sapiens had created art, invented many new tools, made tailored clothing, started counting, and spread to almost all parts of the world. As noted earlier, the oldest known representatives of anatomically modern humans have been found in East Africa, from almost 200,000 years ago. Further evidence of the activities of these individuals comes from caves around Pinnacle Point on the Cape of Good Hope in South Africa and dates to 165,000 years ago. This evidence is not in the form of fossil skeletons, but artifacts. Several finds—small stone blades, pieces of red ochre (an iron mineral used as a pigment), the earliest known collection and consumption of shellfish—point to new kinds of food, new tools that probably required hafting, and the use of powdered mineral as a pigment or preservative. These are firsts in the archaeological record and likely document the beginnings ative explosion witnessed more fully after 50,000 years ago.

Abstract:
Preservation of photographic materials, both physical and digital, presents numerous challenges, and photographic collections are at risk world-wide. In response to this danger, regional partners have worked with international organizations to forge global training initiatives and platforms centred on experiential learning and designed with curricula tailored to speci c climates, geographies, needs and outcomes. paper highlights three forward-thinking e orts. The Middle East Photograph Preservation Initiative (MEPPI) has provided training to collections in 16 countries. Préservation du Patrimoine Photographique Africain (3PA) has connected and empowered talented African archivists, artists and collections care professionals. Training efforts by APOYO have sought to build a regional network to preserve collections in Latin America. By using problem-based learning, advocacy and community engagement, these programmes offer new paths for collaboration in an effort to protect a critical piece of our world heritage.

Abstract:
This paper provides a brief overview of closed sorption cooling technologies, and highlights the research performed on them in the Middle East and North Africa region. The main findings are summarized and presented in tabulated and graphical forms. The reviewed studies are compared in terms of the working pair, the Coefficient of Performance, the normalized collector area, etc. The results show that the average cyclic Coefficient of Performance for the adsorption chillers was 0.41, whereas the average chiller Coefficient of Performance for the absorption chillers was 0.677. The research trends reveal that interest in solar sorption cooling was low in the 1980s and 1990s, and gradually increased during the 2000s. In addition, the most installed solar cooling system in the Middle East and North Africa region is utilizing absorption cycles.

Abstract:
Without frequent cleaning, dust accumulation on parabolic trough collectors can lead to significant degradation of the performance of trough collectors over time. Owing to the nature of the trough profile and the presence of the receiving tube in the middle of the trough, automatic cleaning has not been a feasible option. The problem of dust accumulation is of particular interest in the Middle East/North African (MENA) region with the high frequency of dusty days throughout the year. This paper presents a thermal numerical analysis of a novel vacuum cavity parabolic trough collector (VCPTC) in which the top and the sides of the trough were covered with borosilicate sheets and a vacuum was assumed inside the cavity. The typical vacuum tube used in conventional troughs was replaced by a bare stainless steel pipe with selective coating. The new trough with its flat top surface should now be much easier to clean with an automatic cleaning machine. This paper compares the performance of a conventional trough with the new VCPTC in terms of overall heat loss. The results have shown that the VCPTC has slightly outperformed the conventional trough.

Abstract:
Scarcity of potable water causes a serious problem in arid regions of the world where freshwater is becoming insufficient and expensive. Warm regions in the Middle East and North Africa are considered among the severest water shortage places. The objective of this project is to study the potential of using solar energy to run existing multi-stage flash (MSF) desalination units in the Arabian Gulf. One problem with MSF is the low efficiency of the system because of the bulk energy required for heating. Exploitation of solar energy in thermal desalination processes is a promising technology because of the ubiquitous nature of sun’s energy. Experimental studies were conducted on a single flash desalination unit. The pilot unit demonstrates the use of solar radiation as the thermal energy input. The process starts by preheating seawater through a vacuumed condenser. Seawater, then, flows inside a circulation tank to be indirectly heated by a heat transfer fluid. The heat transfer fluid circulates inside a flat plate solar collector facing south to absorb solar energy. After raising its temperature, seawater goes through an expansion valve and flashes in a vacuumed chamber to form brine and vapor. The vapor transfers to the condenser and condenses to form potable water by losing its latent heat of vaporization to incoming seawater. The flow rate of the working fluid is controlled via a control valve based on a set point temperature reference. The experiments were carried out using different values of the controlling variables to enhance analysis and validate results.

Abstract:
Abstract Particle heating receiver (PHR) based concentrating solar power (CSP) is widely recognized as the preferred path to reliable and cost-effective solar power. Use of solid particles rather than conventional fluids such as molten salts as collection and storage media, enables the operation of the PHR-based CSP plant at elevated temperatures (∼1000°C). This advantage leads to higher efficiency and lower levelized cost of energy (LCOE) produced by PHR-based CSP plants. However, designing and integrating the commercial solar power plant at high operating temperatures (∼1000°C), is a substantial challenge which has been overcome. Our research teams at King Saud University (KSU) and the Georgia Institute of Technology (GIT) have been working on the design and development of high temperature key sub-systems in PHR-based CSP plants. The proposed 1.3 MWe pre-commercial demonstration (PPCD) plant will incorporate the design evolved from our risk-reducing research activities performed at 300kW test facility at KSU and GIT. The DS-PHR of the PPCD will incorporate the KSU’s patented discrete-structured design in which the receiver will be enclosed in a cavity to minimize radiative and convective heat losses. Each PHR panel will have efficient particle flow control system for uniform particles outlet temperatures. Low-cost particulate materials with enhanced solar absorptance and resilience at high-temperatures have been identified to be used as heat collection and storage media. Inexpensive thermal energy storage (TES) bins will accommodate sand with temperatures ∼ 1000 °C. Multiple layered design of the TES bins will limit the heat loss to less than 1% per day (at scale). The current TES design allows easy access to the high-temperature bins for experimental observation and for future modifications. A patent pending skip hoist particle lift system design will be used for particle conveyance with expected mechanical efficiency of 75–85 %. Our lift design is simple, demonstrates autonomous operation with minimal mechanical complexity, minimized heat loss, and reduced maintenance. The heat exchanger proposed is a multi-pass shell-tubes design with high heat transfer coefficient. The design features discussed in this paper will lead to large scale commercial plants and similar small-scale designs for off-grid and remote applications at our anticipated service location which is in Saudi Arabia, and in Mideast and North Africa (MENA) region.
