On 19 September 2002, dissatisfied soldiers in Côte d'Ivoire attempted to overthrow Laurent Gbagbo's regime. In response, France rapidly mobilised its military forces, once again intervening in one of its former colonies. This intervention is all the more surprising given the recent and important reforms in France's Africa policy; reforms which led to the increased disengagement of the French military in Africa. In light of this conundrum, this thesis seeks to understand why France pursued intervention in Côte d'Ivoire in 2002. Moreover, given these wide ranging reforms, I seek to understand t

Résumé :
This chapter discusses the basic incentives that faculty, students, and administrators face, especially at so-called R1 (doctoral-granting with the highest research activity) universities. Different people have somewhat different motivations. Some are more driven by fame and prestige, some by money, some by intellectual curiosity, some by love, and others by a desire to push their ideology. Different institutions also structure their incentives somewhat differently. The university is a political environment where different groups and individuals compete for power and resources. Thus, it is not that the university is full of gremlins or beset by poltergeists, but that individual professors, students, and administrators face incentives that put them in conflict with the core values of the university.

Résumé :
This chapter introduces the authors' approach to university-community engagement as the process of collaborative learning among the young people engaged in afterschool activities run by University-Community Links (UC Links), along with the community and university people who have collectively engaged in designing, planning, and implementing those program activities. The prevalence of social displacement among community participants suggests a primary point for understanding the role that universities can play by engaging in the larger world. The chapter introduces the authors' ethnographic approach to the study of expansive learning among collaborating community and university partners as they confront dilemmas implicit in their engagement in joint activity and come to view their shared activity from an expanded perspective that transforms how they work together. The chapter then describes the historical emergence of UC Links, a California initiative that connects university and community partners in addressing pervasive social displacement and educational inequities.

Résumé :
In the last decades, the discourse about universities and their engagement with actors in their host regions has increased. Concepts such as the third mission and the entrepreneurial university aim to describe the engagement between the university and regional actors as a change in the role of the university. In theory, this is described as a transformation of the university. In practice, this is organised as an add-on of a range of different knowledge-transfer and market-oriented activities, which do not interfere with the core activities of teaching and research. These normative concepts have a significant influence on how universities are developing their regional engagement. In a case study from a university in Norway, University of Agder, the study shows a university that gradually is transforming from an ivory tower model towards more regional engagement. However, the transformation is taking time. At present, the university has a dual strategy for its regional engagement. One part is organised as an add-on activity, while the other is organised within the academic core of teaching. In the latter, students are co-creating knowledge together with regional actors. The study demonstrates that it is possible to organise regional engagement as co-creation of knowledge also within the academic core.

Résumé :
This chapter begins by arguing that universities and scholars have come under criticism for failing to address problems identified as relevant by their stakeholders—the general public—and there is a need to reclaim the civic mission of the university. This need arises as a result of our current inability to deal with “wicked problems.” The development of the modern university is then traced, arguing that while originally it was rooted in the “university as ivory tower” and then evolved into the “university as marketplace partner,” neither is adequate to meet contemporary needs. The university that is emerging—the “university as civic partner”—is described and its implications for scholarship explored. A case study is then presented as a means of illustrating the implicit ideas of this form of emerging scholarship and by reflecting on the case and its implication for how we understand scholarship. The challenges we face in transforming scholarship are then identified and discussed.

Texte intégral
Résumé :
Considerations of the mortuary behavior at Sunghir concern principally the two elaborate graves, Graves 1 and 2. Although each exhibits patterns evident elsewhere in Mid Upper Paleolithic burials, the combinations of features and the richness of the two graves is truly exceptional. Yet there is additional evidence for mortuary behavior, principally associated with the Sunghir 5 cranium and for the burial above Grave 2 (here designated as Grave 2bis). The Sunghir graves have been described in detail by O.N. Bader (1998), and additional analyses of the associated materials have been done by White (1993, 1999) and Khlopachev (2006). Information on them is available from additional sources (e.g., Bader 1978; Soffer 1985; Abramova 1995; Bader and Bader 2000; Pettitt 2011), as well as from numerous short reports. Of these, the primary sources are those of O.N. Bader from the excavations and excavation analysis and of White and Khlopachev from analysis of the original material in the Vladimir District Regional Museum. The description here is an amalgamation of information from these and other sources. There are some inconsistencies between the different sources, and when possible they have been sorted out using the diagrams, and especially the discussion and in situ photographs, provided by O.N. Bader (1998). In the discussions of the graves and their contents, it should be kept in mind that many of the objects found in the graves and clearly associated with the human remains also occur in reasonable numbers in the cultural layer (cf. Bader 1978). This applies to the ochre, the several varieties of ivory beads, small stone pendants, animal figurines, tubular bones, pierced canines (arctic fox and wolf), and ivory spears (or fragments thereof). Additional decorative objects not found in the burials, such as shell beads and engravings, also derive from the cultural layer. It remains unclear whether these finds from the cultural layer were artifacts and aspects of body decoration that were common among the individuals at Sunghir (some of which happened to be preserved in abundance in the graves), whether their occurrence in the cultural layer is the result of pieces lost in the process of preparing the burials, whether the isolated pieces are from disturbed (unknown) burials, or whether (as suggested by Bader 1978) they come from discarded pieces of clothing.

Résumé :
This contribution aims at highlighting some key issues of the evolutionary process of universities, underlining in particular their role in promoting economic development and local communities. The recent shift in paradigm from the ivory tower to the entrepreneurial university has been dramatic and raises both consensus and criticism. This research proposes that this evolutionary process does not entail the emergence of one model of university, on the contrary, it entails the emergence of differentiated models. These possible models can be outlined along the two strategic dimensions of geographic orientation (local, global, glocal) and core activity (teaching, research, both). The glocal university addresses contemporarily the needs and opportunities provided by the local environment together with those deriving from the global one. They develop a two tier system of ties, both local and global, thus enhancing the exposure of the local society and economy to the influence of external knowledge. This contribution proposes a model where a more complex role of universities is highlighted and the “entrepreneurial and technological” paradigm — as suggested by the triple helix model — is complemented by a more comprehensive role, which portraits universities as catalyser of local development also in human and social sciences. Moreover, universities characterise — in some cases distinctively — the urban environment and landscape, thus activating tourists flows, generate a local “culture” not only in terms of goods but also of events and activities, of people and buzz and contribute to connect the local system to the global ones.

Résumé :
You may think of polymers as entirely manufactured and therefore unnatural, but they are often the chemists’ attempts to supplement and improve on the biological polymers that nature produces. Cotton, ivory, leather, linen, paper, rubber, silk, wood and wool are wonderful materials made from the biological polymers that plants and animals produce, and which have evolved to serve such useful ends as providing protective outer layers, insulation, reinforcement, weaponry and so on. Humans learned that with a little modification they could turn these polymers into quite useful articles, such as briefs and briefcases, condoms and tea cosies, tickets and toothpicks. Sometimes we want polymers with features that never evolved in nature, such as non-cracking insulation for electric cable, clothes that can be unpacked after a long voyage and still be without creases, or pans in which to fry eggs without them sticking. For these polymers we have had to look to chemists. Most of the portraits in this Gallery are of these kinds of polymers—materials that do not have natural equivalents. Polymers are rather special kinds of molecules consisting of long chains, usually made up of carbon atoms, to which other atoms, such as hydrogen, fluorine and chlorine, are attached. The older name for polymers is plastics, and you probably know several of them by name— polythene, polystyrene, Teflon, Orion—but these are only a few of the many that now play an important role in our lives. Whatever role polymers play, they cause many of us to adopt quite strong attitudes towards them. A few of us admire them, many of us ignore them, but a growing number despise them and a few abhor them and will avoid them at all costs. To a chemist, this opposition to polymers seems rather strange. By the time you come to the end of this exhibition I hope that visitors with strong views will have seen enough to persuade them to change their mind. Attitudes towards plastics have changed over the past half-century. In the 19305, when cellophane, PVC, polystyrene, Perspex and nylon were launched, plastics were welcomed.
