Hominid evolution in the late Miocene has long been hypothesized to be linked to the retreat of the tropical rainforest in Africa. One 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 impacted rainfall distribution over Africa. Recent proxy data suggest that in East Africa open grassland habitats were available to the common ancestors of hominins and apes long before their divergence and do not find evidence for a closed rainforest in the late Miocene. We used the coupled global general circulation model CCSM3 including an interactively coupled dynamic vegetation module to investigate the impact of topography on African hydro-climate and vegetation. We performed sensitivity experiments altering elevations of the Himalaya and the Tibetan Plateau as well as of East and Southern Africa. The simulations confirm the dominant impact of African topography for climate and vegetation development of the African tropics. Only a weak influence of prescribed Asian uplift on African climate could be detected. The model simulations show that rainforest coverage of Central Africa is strongly determined by the presence of elevated African topography. In East Africa, despite wetter conditions with lowered African topography, the conditions were not favorable enough to maintain a closed rainforest. A discussion of the results with respect to other model studies indicates a minor importance of vegetation-atmosphere or ocean-atmosphere feedbacks and a large dependence of the simulated vegetation response on the land surface/vegetation model.

The bilateral relationship between the EU and China has a tendency toward growth in recent years. At present, China’s economic development is at a critical transition period for deepening reform in the economic structure. The economic and trade cooperation with the countries of the European Union has a significant influence for the stability of trade development and economic growth. Therefore China tries to expand cooperation and eliminate the issues and difficulties that exist, it will more often to promote cooperation between the two parties towards deeper into various cooperative areas.

International migration sets in motion a range of significant transnational processes that connect countries and people. How migration interacts with development and how policies might promote and enhance such interactions have, since the turn of the millennium, gained attention on the international agenda. The recognition that transnational practices connect migrants and their families across sending and receiving societies forms part of this debate. The ways in which policy debate employs and understands transnational family ties nevertheless remain underexplored. This article sets out to discern the understandings of the family in two (often intermingled) debates concerned with transnational interactions: The largely state and policydriven discourse on the potential benefits of migration on economic development, and the largely academic transnational family literature focusing on issues of care and the micro-politics of gender and generation. Emphasizing the relation between diverse migration-development dynamics and specific family positions, we ask whether an analytical point of departure in respective transnational motherhood, fatherhood or childhood is linked to emphasizing certain outcomes. We conclude by sketching important strands of inclusions and exclusions of family matters in policy discourse and suggest ways to better integrate a transnational family perspective in global migration-development policy.

Historical archaeology, in its narrow temporal sense -as an archaeology of the emergence and subsequent evolution of the Modern world- is steadily taking pace in Spanish academia. This paper aims at provoking a more robust debate through understanding how Spanish historical archaeology is placed in the international scene and some of its more relevant particularities. In so doing, the paper also stresses the strong links that have united historical and prehistorical archaeology since its inception, both in relation to the ontological, epistemological and methodological definition of the first as to the influence of socio-political issues in the latter. Such reflection is partly a situated reflection from prehistory as one of the paper’s authors has been a prehistorian for most of her professional life.

BACKGROUND: Multiyear epidemics of Salmonella enterica serovar Typhi have been reported from countries across eastern and southern Africa in recent years. In Blantyre, Malawi, a dramatic increase in typhoid fever cases has recently occurred, and may be linked to the emergence of the H58 haplotype. Strains belonging to the H58 haplotype often exhibit multidrug resistance and may have a fitness advantage relative to other Salmonella Typhi strains.
METHODS: To explore hypotheses for the increased number of typhoid fever cases in Blantyre, we fit a mathematical model to culture-confirmed cases of Salmonella enterica infections at Queen Elizabeth Central Hospital, Blantyre. We explored 4 hypotheses: (1) an increase in the basic reproductive number (R0) in response to increasing population density; (2) a decrease in the incidence of cross-immunizing infection with Salmonella Enteritidis; (3) an increase in the duration of infectiousness due to failure to respond to first-line antibiotics; and (4) an increase in the transmission rate following the emergence of the H58 haplotype.
RESULTS: Increasing population density or decreasing cross-immunity could not fully explain the observed pattern of typhoid emergence in Blantyre, whereas models allowing for an increase in the duration of infectiousness and/or the transmission rate of typhoid following the emergence of the H58 haplotype provided a good fit to the data.
CONCLUSIONS: Our results suggest that an increase in the transmissibility of typhoid due to the emergence of drug resistance associated with the H58 haplotype may help to explain recent outbreaks of typhoid in Malawi and similar settings in Africa.

Germany, Italy and Japan were engaged in China from the turn of the 20th century to WWII. However, they formed an anti-Chinese alliance only at the final stage of their presence there, when Japan assumed an undisputed role of leader in the region. Despite its alliance with the Axis powers, Japan never implemented racial laws against the Jews in China. All of them took part in the Boxer Upraising suppression and received as a consequence extraterritorial rights and concessions. Moreover, Japan won the war against China in 1895 and transformed itself from a tributary country of China into an imperialistic power. It took possession of Taiwan and in the 1930s established a puppet government in Manchuria.Germany followed different route obtaining as indemnity for the murders of two missionaries the control of the Shandong province, which was later expanded thanks to the anti-Boxer coalition's victory. However, Germany lost all possessions when China entered WWI. The issue of Shandong was finally resolved at the Conference for Disarmament hold in Washington in 1921-2. Japan failed to gain ex-Germany territories. Finally, Italy arrived in the Far East at the turn of the century but was not very interested in the oriental colonialism to the same extent it was interested in Africa. Tianjin was its only concession in China, and it took almost a decade before a subvention to arrive from the Italian government for its development.In the 1920s and 1930s Germany and Italy engaged in successful diplomatic, commercial and military relationships with China. In fact, both were considered China's partners thanks to their experts at the service of the Chinese government. On the other hand, Japan position was opposite to them, because of its plans of aggression towards China which was to be transformed into “the natural extension” of the mainland. In 1935 Italy declared war on Ethiopia and abandoned the seat at the League of Nations. China interpreted the Italian aggression as the endorsement of Japan's politics towards China in Manchuria, and the relations between the two countries were broken off. After that Italy supported Wang Jingwei's puppet government during the Japanese occupation of China. Germany followed the same path in 1937, when it was evident that the Japanese were playing the leading role in the region, and decided to ally with Wang Jingwei too. Both Italy and Germany decided also to recognise the Manzhuguo and established diplomatic relations, definitively turning their backs on the old Chinese ally.The Rome-Berlin-Tokyo Axis sealed the alliance among the three countries, and it confirmed Japan as the leading power in the region. Nevertheless Japan did not apply the racial law against the Jews in China.

BACKGROUND: -There are few contemporary data on the mortality and morbidity associated with rheumatic heart disease (RHD) or information on their predictors. We report the two year follow-up of individuals with RHD from 14 low and middle income countries in Africa and Asia.
METHODS: -Between January 2010 and November 2012, we enrolled 3343 patients from 25 centers in 14 countries and followed them for two years to assess mortality, congestive heart failure (CHF), stroke or transient ischemic attack (TIA), recurrent acute rheumatic fever (ARF), and infective endocarditis (IE).
RESULTS: -Vital status at 24 months was known for 2960 (88.5%) patients. Two thirds were female. Although patients were young (median age 28 years, interquartile range 18 to 40), the two year case fatality rate was high (500 deaths, 16.9%). Mortality rate was 116.3/1000 patient-years in the first year and 65.4/1000 patient-years in the second year. Median age at death was 28.7 years. Independent predictors of death were severe valve disease (hazard ratio (HR) 2.36, 95% confidence interval (CI) 1.80-3.11), CHF (HR 2.16, 95% CI 1.70-2.72), New York Heart Association functional class III/IV (HR 1.67, 95% CI 1.32-2.10), atrial fibrillation (AF) (HR 1.40, 95% CI 1.10-1.78) and older age (HR 1.02, 95% CI 1.01-1.02 per year increase) at enrolment. Post-primary education (HR 0.67, 95% CI 0.54-0.85) and female sex (HR 0.65, 95%CI 0.52-0.80) were associated with lower risk of death. 204 (6.9%) had new CHF (incidence, 38.42/1000 patient-years), 46 (1.6%) had a stroke or TIA (8.45/1000 patient-years), 19 (0.6%) had ARF (3.49/1000 patient-years), and 20 (0.7%) had IE (3.65/1000 patient-years). Previous stroke and older age were independent predictors of stroke/TIA or systemic embolism. Patients from low and lower-middle income countries had significantly higher age- and sex-adjusted mortality compared to patients from upper-middle income countries. Valve surgery was significantly more common in upper-middle income than in lower-middle- or low-income countries.
CONCLUSIONS: -Patients with clinical RHD have high mortality and morbidity despite being young; those from low and lower-middle income countries had a poorer prognosis associated with advanced disease and low education. Programs focused on early detection and treatment of clinical RHD are required to improve outcomes.

This PhD thesis focuses on current livelihoods of agro-pastoral livestock keepers, their animal nutrition, herd and rangeland management strategies. It thereby aims to contribute to sustainable rangeland management, livestock production and household income in Qinghe county of the Chinese Altay Mountain region, located in Xinjiang Uyghur Autonomous Region, PR China. In its first part the study characterizes the socio-economic situation and agricultural practices of agro-pastoralists through structured household interviews. The second part provides insights into the grazing behaviour and feed intake of small ruminants on seasonal pastures in this region, and into the quantitative and qualitative biomass offer on natural rangelands. The third part analyses the reproductive performance and annual growth of the local sheep and goat herds, and, by modelling improved feeding and culling strategies, tests herd management options that potentially improve the monetary output per female herd animal without increasing the pressure onto natural rangelands. Taken together, the results of the study suggest that, despite an increase and intensification of cropping and vegetable gardening in the region of Qinghe, livestock rearing is still the major livelihood strategy both in terms of prevalence and relative importance. However, livestock keeping is challenged by low biomass production on rangelands, due to the combined impact of high climate variability and highly localized grazing pressure on the seasonal pastures. Though government regulations try to tackle the latter aspect, their implementation is sometimes difficult. Alternatives to strict regulation of grazing periods and animal numbers on seasonal pastures are, in the case of goats, more rigorous culling strategies and, in the case of sheep and goats, strategic supplementation of the animals in the winter and spring season. However, for the latter strategy to become economically viable, an improvement of live animal and meat marketing options and an investment in local meat processing facilities that add value to the carcasses is needed. As the regional cities grow rapidly, the potential market to absorb diverse and good quality meat products is there, along with the road network connecting Qinghe county to the regional capital. Such governmental measures will not only create new job opportunities in the region but also benefit the cash income of pastoralists in this westernmost region of China.

Th is article seeks to analyze, in a socio-historical perspective, the formation of the Nation in Cape Verde. It argues that the archipelago took a singular path in Nation-building in Africa, through a combination of diff erent dimensions: social, geographical, political and religious, educational, administrative and literary. It is particularly important to understand these dimensions, since the Cape Verdean Nation precedes in centuries the creation of the independent State. Th is route was accompanied by the social mobilization of the mestizo, who, since the end of the 16th century, has been the main subject in the history of the archipelago.

Purpose- Entrepreneurship education (EEd) plays a crucial role in the development of entrepreneurs and the enhancement of entrepreneurial activities in every economy. This paper examined what Higher education Institutions (HEIs) do in learning and teaching of entrepreneurship in general and how entrepreneurship development takes place in Nigerian HEIs. The outcome from this study will enable a deeper understanding on what HEIs do EEd, with more exposure as to what the areas and focus of research is in the Nigerian context. Design/methodology/approach- The study adopted a systematic literature review approach- drawing from a computerized search of five selected data bases, using predetermined key words by the researchers. Findings: The main finding of this paper is that, related concepts like skills, intention, drive and attitude have been use in expounding discussions on the outcome of EEd, but very little has been written on entrepreneurial mind-set (EMS), of which other studies have suggested that it’s a crucial point in the journey of an entrepreneurs (Reed & Stoltz, 2011; Quality Assurance Agency for Higher Education (QAA), 2012; Neneh, 2012). Furthermore, learning and teaching of entrepreneurship in Nigerian HEIs seems to be more on creating awareness (about entrepreneurship) than actual preparation for entrepreneurship (For entrepreneurship). Research limitations/implications- The paper is limited since it is based on a review of literature from a selected databases- covering a specific time span. This potentially excludes other studies outside this time span. A more comprehensive overview of these contributions would benefit from employing tools such as Google Scholar, for an overview of the sub–domains online. Originality/value – There are limited studies that focus on the issue of entrepreneurial mind-set in entrepreneurship education in Africa, specifically Nigeria. This paper and its focus in particular, have laid down pioneering ground work for research on entrepreneurial mind-set development in Nigerian entrepreneurship education.
