Securely computing a similarity measure

The present invention relates to a method and a system of securely computing a measure of similarity for at least two sets of data. A basic idea of the present invention is to securely compare two sets of encrypted data to determine whether the two sets of data resemble each other to a sufficient extent. If the measure of similarity complies with predetermined criteria, the two sets of data from which the encrypted sets of data originate are considered to be identical

Cultures of travel: Fulbe pastoralists in central Mali and Pentecostalism in Ghana

In the literature on population mobility, mobility has generally been seen as a temporary phenomenon. However, in many instances, mobility rather than sedentarity is the norm. This is illustrated in the present chapter by two case studies of so-called 'cultures of travel'. The first case concerns the Fulbe, a nomadic cattle-rearing people, in the Hayre area of central Mali. The Fulbe case demonstrates how mobility has been embedded historically in Sahelian cultures under conditions that are marginal, both from an ecological and an economic perspective. It illustrates how people develop economic and cultural strategies marked by a high degree of opportunism. It shows that Fulbe society is, in fact, organized around mobility. The second case, that of Pentecostalism in Ghana, demonstrates how a specific form of culture acts to bring about a particular form of mobility. In this case, it is not a whole culture that is on the move, but individuals who are mobile for personal reasons. Mobility among Ghanaian Pentecostalists is not yet part and parcel of daily life, but presents an example of how people construct cultural forms and means for dealing with everyday problems of mobility.

Arid ways: cultural understandings of insecurity in Fulbe society, Central Mali

This thesis deals with the ways in which the agropastoral Fulbe in the Sahel deal with ecological, social and political insecurities. It is based on field research carried out in the Hayre dryland region of central Mali, notably in the villages of Dalla and Serma, from March 1990 until February 1992. The first part of the study examines the history of natural resource management and ideologies in the Hayre (1400-1985). The second part is about the role of the past in the present. It analyses the spatial organization, ecological environment, economic organization, and division of labour in the area, as well as the normative complexes typical of Fulbe society. Part three focuses on the use and management of natural resources, paying attention to farming and herding practices, agricultural and pastoral production, the circulation of property, and land tenure. Part four is concerned with the way in which people who have been pushed out of agricultural production survive. It focuses in particular on how people manage social and cultural resources. Part five deals with the interactions of the Fulbe pastoralists with the State and the outside world in a situation of droughtASC – Publicaties niet-programma gebonde

Landgebruik en landbouwstrategieën in het Dogongebied

Het Dogongebied maakt deel uit van de regio Mopti en behoort tot de armste gebieden van Mali. De economie van het gebied is gebaseerd op de graanbouw voor eigen gebruik en op de veeteelt voor vlees en melk. Voor enkele bewoners die op het Plateau van Bandiagara leven, is tuinbouw de enige bron van inkomsten. In de afgelopen decennia heeft de technologische ontwikkeling een versnelde groei van landbouwgronden met zich meegebracht. Hoewel de productie sinds lange tijd schijnt af te nemen onder invloed van de droogte, is de totale productie niet gedaald dankzij de snelle groei van het landbouwareaal. De landbouwstrategieën van de Dogon worden hier besproken per agro-ecologische zone: graanbouw, uienteelt en marginale veeteelt op het Plateau van Bandiagara, en veeteelt, graanbouw, oasen, steun en handel in de vlakten.
