In East Africa there is a field research station that locals call ‘Atlanta.’ It sits on the outskirts of a rural town, near Lake Victoria, equipped with ‘state-of-the-art’ biotechnological and entomological equipment for monitoring and exploring malaria, HIV, tuberculosis, rotavirus, and other tropical diseases. Drawn from ethnographic fieldwork with clinical trials in East Africa, this paper considers the stories people tell about the landscapes and spaces of experimental medicine to explore the uneven movement of knowledge, scientific practices, and scientists in global medicine. I begin this analytical journey at ‘Atlanta’ to consider what local idioms about such places might tell us about the encounters and travels of science and scientists in East Africa. Last, I draw attention to the social and material effects of global science projects on the lives and landscapes of East Africa.

Matrix Factorization Technique

Collaborative filtering suffers from the problems of data sparsity and cold start, which dramatically degrade recommendation performance. To help resolve these issues, we propose TrustSVD, a trust-based matrix factorization technique. By analyzing the social trust data from four real-world data sets, we conclude that not only the explicit but also the implicit influence of both ratings and trust should be taken into consideration in a recommendation model. Hence, we build on top of a state-of-the-art recommendation algorithm SVD++ which inherently involves the explicit and implicit influence of rated items, by further incorporating both the explicit and implicit influence of trusted users on the prediction of items for an active user. To our knowledge, the work reported is the first to extend SVD++ with social trust information. Experimental results on the four data sets demonstrate that our approach TrustSVD achieves better accuracy than other ten counterparts, and can better handle the concerned issues.

Care Of Elderly

The European society is getting older and nobody knows how to deal with this problem. There are different models from family care, special housing for elderly to professional institutional care, which has the disadvantage of being very expensive. In Germany we have noticed in the last two or three years a special trend to send old people suffering from dementia to foreign countries, because these people need intensive care and the social services for example in Poland have a high standard. The aim of our survey is to dismantle, by the example of the private care institution situated in Poland, Upper Silesia which specializes on German customers, the social practices associated with placing the elderly in such institutions and also the methods of constructing meanings of these practices providing clarity in the various groups that take part in this process. To reach this aim we used qualitative field research, including discourse and narrative analysis of various materials (interviews, promotional texts, websites), which beside other things allowed us to reconstruct the media image of the surveyed residences for the elderly and show it in a wider context.

Mode Of Production

This chapter addresses a very simple question: is it possible to frame coinage in the Early Middle Ages? The answer will be certainly yes, but will also acknowledge that we lack considerable amounts of relevant data potentially available through state-of-the-art methodologies. One problem is, though, that many times we do not really know the relevant questions we can pose on coins; another is that we still have not figured out the social role of coinage in the aftermath of the Roman Empire. This chapter shows a number of things that could only be known thanks to the analysis of coins. And as its title suggests it will also include some reflections on greed and generosity.

The 19Th Century

Brokers have played important roles in the trade of green tea between China and Mali, from the 19th century when tea first came to Mali up to the present. They mediate between tea buyers and sellers, work on their own account, use soft skills, knowledge and networks and make a living from the commission they gain. This article examines the work of brokers in the tea trade, the social constellations in which they are active and the scope of their activity. Based on extensive field research in Mali and China, this article shows how brokers create their own jobs in a dynamic business landscape, which is often delimited by governmental policies, competing entrepreneurial activities and social movements.

Circular economy (CE) is an economic model, in which raw materials remain in circulation as long as possible and the generation of waste is minimized. In the fertilizer sector, waste rich in nutrients should be directed to agriculture purposes. This paper presents an analysis of recommended directions for the use of nutrient-rich waste in fertilizer sector and an evaluation of possible interest in this kind of fertilizer by a selected group of end-users (nurseries). The scope of research includes the state-of-the-art analysis on circular aspects and recommended directions in the CE implementation in the fertilizer sector (with focus on sewage-based waste), and survey analysis on the potential interest of nurseries in the use of waste-based fertilizers in Poland. There are more and more recommendations for the use of waste for agriculture purposes at European and national levels. The waste-based products have to meet certain requirements in order to put such products on the marker. Nurserymen are interested in contributing to the process of transformation towards the CE model in Poland; however, they are not fully convinced due to a lack of experience in the use of waste-based products and a lack of social acceptance and health risk in this regard. Further actions to build the social acceptance of waste-based fertilizers, and the education of end-users themselves in their application is required.

ABSTRACT This paper addresses the case of five lack entrepreneurs who own businesses a public that for years has denied a esthetic and phenotypic traits. These spaces, branded as ‘ethnic salons’, aim to take care of the curly and / or Afrohair of Black men and women.In the face of this context, we ask: how canBlack entrepreneurs and enterprisesconfront colonialmentality in social relations, by creating businesses aimed at giving value to, and appreciatingthe identity of Black men and women? The field research was conducted via observations and interviews,collecting narratives from both. The narratives went through a process of synthesis and analysisprocesses that allowed us to flag the motivesbehind these enterprises, as well as the racial/ethnic acceptance present in these spaces. Thus, the main contribution of this paper is to discuss ‘hairtype’ as a constitutive element of Black racial identity, and the opportunity for more autonomywhen entering the labor market.
