A baseline study of vicine–convicine levels in faba bean (Vicia faba L.) germplasm

Vicine and convicine are anti-nutritional compounds that accumulate in the cotyledons of faba beans. When humans consume beans with high levels of these compounds, it can cause a condition called favism in individuals harbouring a deficiency in the activity of their glucose-6-phosphate dehydrogenase. When faba beans are used in animal feeds, there can be effects on performance. These concerns have resulted in increasing interest within plant breeding in developing low vicine and convicine faba bean germplasm. In order to facilitate this objective, we developed a rapid and robust screening method for vicine and convicine, capable of distinguishing between faba beans that are either high (wild type) or low in vicine and convicine. In the absence of reliable commercial reference materials, we report an adaptation of a previously published method where a biochemical assay and spectral data were used to confirm the identity of our analytes, vicine and convicine. This method could be readily adopted in other facilities and open the way to the efficient exploitation of diverse germplasm in regions where faba beans play a significant role in human nutrition. We screened a collection of germplasm of interest to a collaborative plant breeding programme developing between the National Institute for Agricultural Botany in the UK and L'Institut Nationale d'Agronomie de Tunisie in Tunisia. We report the results obtained and discuss the prospects for developing molecular markers for the low vicine and convicine trait.

Der Kampf um den 19. März: Zur gesellschaftlichen Auseinandersetzung um das Totengedenken der Algerienkriegsveteranen in Frankreich

Der Beitrag behandelt die Entwicklung der geschichtspolitischen Auseinandersetzungen um den 19. März, den die 'Fédération Nationale des Anciens Combattants en Algérie, Maroc, Tunisie' ( FNACA) als führender Verband der französischen Algerienkriegsveteranen zum Totengedenktag für ihre zwischen 1954 und 1962 gefallenen Kameraden erklärt hat. Der 19. März 1962 steht als Tag des Waffenstillstandes zwischen der französischen Kolonialarmee und der algerischen Nationalen Befreiungsbewegung FLN ('Front de Libération Nationale') für den Frieden in Algerien. Ihm haftet zugleich der Geruch der Kapitulation vor den 'Rebellen' an, da er den Prozess einleitete, der zur Unabhängigkeit Algeriens führte. Die verschiedenen Regierungen der Fünften Republik weigerten sich beharrlich, den 19. März als Feiertag anzuerkennen, da er als Datum zur Aussöhnung der im Algerienkrieg zerrissenen Nation nicht geeignet sei. Stattdessen wurden die von der FNACA organisierten Gedenkaktivitäten seit den 1970er Jahren regelmäßig zur Zielscheibe polemischer Angriffe aus dem Lager jener rechten politischen Kräfte, die weiterhin das Erbe des französischen Kolonialismus in Algerien verteidigten.

Gender differences at the transition to higher education between migrants and non-migrants: A comparison between Switzerland and France

Within Western societies women or girls meanwhile outperform men or boys with regard to attainments in primary and secondary education. For example concerning upper secondary degrees the share of females attaining the Matura approaches two thirds in Switzerland, while the share of females attaining the Baccalaureate exceeds fifty per cent in France. However, if transitions to higher education are regarded, the share of entitled females entering such institutions is significantly lower than among men in Switzerland. An opposite pattern is observed in France where females outperform men at this educational stage, too. With regard to migrant background, it has been shown by previous research focussing on secondary effects of ethnic origin that such youths enter the more demanding educational tracks (e.g. higher education) more often than their non-migrant peers if controlled for eligibility, their lower socioeconomic status and performances. However, so far only a few studies refer to the question of a possible gender gap regarding secondary effects of ethnic origin (e.g. Fleischmann et al., mimeo). Thus, with regard to a possible interaction of a migrant background and - for example - a female gender, it is important to note that in both countries many migrant groups have their origins in countries and regions where male advantage remains very strong. This is in particular the case for migrant groups from non-Western countries, e.g. Turkey, Algeria, Marocco or Tunisie, where gender gaps in the literacy rates of up to 18 per cent are still observed. In order to investigate the question of a possible disadvantages of women with a migrant background stemming from such countries when compared to non-migrant females two panel studies - the Tree data in Switzerland and the Panel d’élèves 1995 in France -, are analysed.

Emerging Identities in Colonial Tunisia: "Alliancist" and Zionist Representations in Tunis prior to World War I

By 1900 the Jewish community of Tunisia witnessed the emergence of new competing identities: “assimilationist” of the Alliance Israelite Universelle, termed “Alliancist,” and Zionist. Strikingly, two members of the same family in Tunis, Raymond Valensi, President of the AIU Regional Committee, and Alfred Valensi, President of the Zionist Federation, led the struggle for their separate causes. In his discussion of identity in the modern world, Homi Bhabha asks, "How do strategies of representation or empowerment come to be formulated in the competing claims of communities…where, despite shared histories of …discrimination, the exchange of values, meanings and priorities…may be profoundly antagonistic…?" It is in this context that the claims of the Alliance and Zionism will be examined prior to World War I, based on the Archives of the AIU and on such secondary sources as the indispensable work of Paul Sebag. The tensions between the Alliancists and Zionists continued until the outbreak of World War II, as the French-speaking Jews of Tunisia sought to define their individual and collective identities.
