The “Belle Epoque” saw the revival of the colonial idea in new forms. A second European colonization wave washed over Africa. King Leopold II unfolded his activities in Congo from 1876 onwards. There, his efforts to develop a so-called “philanthropic” enterprise soon evolved in a process of state formation, overshadowed by intrigues and tensions that were a consequence of colonial competition between the Western powers. Only a decade later, at the Berlin Conference of 1885, a definite arrangement was adopted. Everywhere in Europe, a disputed transition was made from liberal to more conservative ways of government. Of course this tension field also dominated intellectual life. There was an intense debate between partisans of colonialism and supporters of worldwide free trade. For the development of his colonial doctrine Leopold II had been inspired by intellectuals that supported economic expansionism. Most of them were active in the field of economic geography. But the King also searched for support in other academic circles and mobilized Emile de Laveleye (1822-1892), one of Europe’s brightest minds, to join him in his quest for the most adequate economic, social and political model of a future state in the heart of Africa. In his books, articles and pamphlets, the liberal minded political economist de Laveleye showed himself an unshakable opponent of colonization and imperialism. However, in the period 1875-1885 – a decade so crucial for Congo – a surprising intellectual rapprochement between de Laveleye and Leopold II was established. For a certain time, this competent man of science advised the King, putting into royal service an intellectual network of European range. This paper investigates how, in the complex and constantly evolving public discussion about Congo, two apparently opposing minds attracted each other. We focus on de Laveleye’s important pleas for a “neutral and international formula” that would place Leopold II in a conflicting situation with Portugal and France. This study shows that, in the years preceding the Berlin Conference, de Laveleye got actively involved in a carefully orchestrated European media campaign in support of Leopold’s initiative. It was there that his intellectual circle became extremely useful and was fully implicated. His contacts among experts of international law contributed to the important discussions about Congo’s juridical status. De Laveleye’s colleague Sir Travers Twiss, as well as the influential Institut de droit international, of which de Laveleye had been one of the founders, entered the debate zone and took positions which were favorable for Leopold’s project. With this new approach, our paper also aims to give insight in the way Leopold II transformed his own reasoning into a more authoritative set of practical standards which were shared by an intellectual elite.

Nous développons un modèle dans lequel les travailleurs peuvent avoir tendance à trop travailler quand ils sont jeunes, parce qu’ils ne peuvent ou ne veulent pas voir les conséquences que cela peut avoir sur leur santé et sur leur capacité à travailler longtemps. Pour les obliger à mieux répartir leurs efforts sur leur cycle de vie, une taxe sur les revenus du travail en début de vie et une subvention de l’épargne sont souhaitables. Si la subvention de l’épargne n’est pas disponible, la taxe optimale arbitre entre quatre considérations différentes. Nous étudions également la taxe optimale quand les individus diffèrent en productivité. [less ▲]

Regression is a commonly used technique for describing the relationship between a response variable and one or more explanatory variables. When the response variable is a categorical variable, usual regression based on ordinary least squares should be replaced by logistic regression. Binary logistic regression should be used to perform a regression on a dichotomous response. Nominal polytomous logistic regression applies to a categorical response variable that has more than two levels with a natural ordering. And ordinal polytomous logistic regression is used when the response is a categorical variable that has more than two levels with a natural ordering. This note gives an overview of these logistic regression methods and describes three models commonly used when performing ordinal logistic regression. These models are illustrated by an example related to oak decline in the Walloon Region (Belgium). [less ▲]

The cuticular hydrocarbons of insects are species-specific and often function as semiochemicals. The activity of Tribolium brevicornis cuticular hydrocarbons as feeding deterrents that ostensibly function to prevent pupal cannibalism and predation was evaluated. The cuticular hydrocarbons of T. brevicornis pupae were characterized and flour disk bioassays conducted with individual and combined extract components incorporated into artificial diets on which Tribolium adults fed for six days. Feeding by T. brevicornis and T. castaneum on flour disks containing cuticular extracts of T. brevicornis pupae resulted in reduced consumption and weight loss relative to feeding on control flour disks. In both cases, feeding deterrence indices exceeded 80% suggesting that T. brevicornis cuticular hydrocarbons could function to deter cannibalism and predation of pupae by larvae and adult beetles. Sixteen different cuticular hydrocarbons were identified in T. brevicornis pupal extracts. Eight of the commercially available linear alkanes were tested individually in feeding trials with eight Tribolium species. One compound (C28) significantly reduced the amount of food consumed by three species compared to control disks, whereas the compounds C25, C26, and C27elicited increased feeding in some species. Four other compounds had no effect on consumption for any species. When four hydrocarbon mixtures were tested for synergistic deterrence on T. brevicornis and T. castaneum, none significantly influenced consumption. Our results indicate that the cuticular chemistry of T. brevicornis pupae could serve to deter predation by conspecific and congeneric beetles. [less ▲]

The study looked into the current scenario of food security in Rwanda. After analysing the national level institutional and food security scenarios by using available secondary data, the researchers used primary data that have been collected from a random sample of 200 households spreading over six sectors of the Huye district by using structured interview schedule, as well using a case study of a rice cooperative in Huye district. Focus group discussions with all stake holders concerned with food security at local level enriched the data that we collected by other means. The general conclusion that emerges from the study is that in order to attain the food security at local level in Rwanda lot more to be done. Among other things, strengthening existing local institutions like farmer cooperatives, improving agricultural production technology, diversifying household income sources for better access, and genuine integration of food security concerns in the district development plans. The researchers come out with certain policy recommendations that may make the local level food security more sustainable which includes, among others, the orientation of the households well into the new modes of agricultural production and planning of household income. The need for much more local level institutional support in many areas is highlighted. On the whole, the study addressed the concerns of food access among rural households in Rwanda, and also the much wanted institutional support being exposed. [less ▲]

Bone fracture healing is a complex process in which angiogenesis or the development of a blood vessel net work plays a crucial role. In this paper, a mathematicalmodel is presented that simulates the biological aspects of fracture healing including the formation of individual blood vessels. The model consists of partial differential equations, several of which describe the evolution in density of the most important cell types, growth factors, tissues and nutrients. The other equations determine the growth of blood vessels as a result of themovement of leading endothelial (tip) cells. Branching and anastomoses are accounted for in the model. The model is applied to a normal fracture healing case and subjected to a sensitivity analysis. The spatiotemporal evolution of soft tissues and bone, as well as the development of a blood vessel network are corroborated by comparison with experimental data. Moreover, this study shows that the proposed mathematical framework can be a useful tool in the research of impaired healing and the design of treatment strategies. [less ▲]

Analysing spatial familiarity aims to measure how places included in the life-world and in the cognitive map are familiar. Based on the study of Gale, Golledge, Halperin & Couclelis (1990), this paper explores the spatial familiarity of the inhabitants of two municipalities at the fringe of Liege (Belgium): it questions the links between the cognitive dimensions (visual, nominal, localisation) and themselves and the behavioural dimension (passing). It seeks new relevant places for the population of these urban fringe as well as the favourable factors to a good familiarity of a place. Finally, it scrutinizes the influence of people's mobility – period of residence, commuting to work, modes of transport – on spatial familiarity. [less ▲]

This paper presents a review of studies that were aimed at determining which brain regions are recruited during visual self-recognition, with a particular focus on self-face recognition. A complex bilateral network, involving frontal, parietal and occipital areas, appears to be associated with self-face recognition, with a particularly high implication of the right hemisphere. Results indicate that it remains difficult to determine which specific cognitive operation is reflected by each recruited brain area, in part due to the variability of used control stimuli and experimental tasks. A synthesis of the interpretations provided by previous studies is presented. The relevance of using self-recognition as an indicator of self-awareness is discussed. We argue that a major aim of future research in the field should be to identify more clearly the cognitive operations induced by the perception of the self-face, and search for dissociations between neural correlates and cognitive components.
