Construction d'Orthogonaux dans les Groupes abéliens finis eet confusions d'effets dans les plans factoriels
RĂ©sumĂ©Cet article est consacrĂ© aux plans factoriels obtenus par la mĂ©thode DSIGN de Patterson (1976). Comme Bailey (1977) l'a montrĂ© l'Ă©tude des confusions d'effets dans ces plans d'expĂ©riences peut ĂȘtre menĂ©e en recherchant les orthogonaux de sousgroupes du groupe abĂ©lien fini des traitements. Le mĂȘme procĂ©dĂ© permet Ă©galement de construire des plans vĂ©rifiant des confusions d'effets donnĂ©es. Nous prĂ©sentons ici un algorithme de construction de tels orthogonaux qui passe par la dĂ©composition primaire du groupe des traitements puis par la construction d'orthogonaux dans des p-groupes.AbstractThis paper is devoted to factorial designs generated by Patterson's (1976) DSIGN method. As stated by Bailey (1977), the identification of confounded effects may be done here by constructing annihilators of given subgroups of the treatment group
LâintĂ©gration de la relation du master and disciple dans lâespace constitutionnel
La relation entre master and disciple, sa transposition, voire sa rĂ©Ă©laboration dans le contexte du Maroc indĂ©pendant, ne peut quâĂȘtre fascinante. Elle reprĂ©sente un processus pourvu de dynamismes succeptible de nous Ă©clairer sur plusieurs Ă©lĂ©ments constitutifs de la pratique politique et constitutionnelle qui peuvent Ă©chapper aux politologues et aux constitutionnalistes. En dĂ©pit de cet Ă©clairage et de cette fascination, la relation du maĂźtre et du disciple nous interpelle dans la mesure oĂč ..
Recommended distances for physical distancing during COVID-19 pandemics reveal cultural connections between countries
Recommended distances for physical distancing during COVID-19 pandemics reveal cultural connections between countries
During COVID-19 pandemic several public health measures were implemented by diverse countries to reduce the risk of COVID-19, including social distancing. Here we collected the minimal distance recommended by each country for physical distancing at the onset of the pandemic and aimed to examine whether it had an impact on the outbreak dynamics and how this specific value was chosen. Despite an absence of data on SARS-CoV-2 viral transmission at the beginning of the pandemic, we found that most countries recommended physical distancing with a precise minimal distance, between one meter/three feet and two meters/six feet. 45% of the countries advised one meter/three feet and 49% advised a higher minimal distance. The recommended minimal distance did not show a clear correlation with reproduction rate nor with the number of new cases per million, suggesting that the overall COVID-19 dynamics in each country depended on multiple interacting factors. Interestingly, the recommended minimal distance correlated with several cultural parameters: it was higher in countries with larger interpersonal distance between two interacting individuals in non-epidemic conditions, and it correlated with civil law systems, and with currency. This suggests that countries which share common conceptions such as civil law systems and currency unions tend to adopt the same public health measures

Dâune intifĂąda lâautre. La Palestine au quotidien
Depuis le dĂ©clenchement, en septembre 2000 Ă JĂ©rusalem, de la seconde intifĂąda palestinienne, ou intifĂądat al-Aqsa, il est devenu aussi facile de s'informer que difficile de donner un sens aux faits massivement exposĂ©s dans les mĂ©dias. L'information circulant sur les Ă©vĂ©nements de Palestine a en effet augmentĂ© en quantitĂ© et en intensitĂ© dramatique. La rapiditĂ© de sa transmission et le caractĂšre hĂ©tĂ©rogĂšne des sources et de leur traitement rendant malaisĂ©e la comprĂ©hension de ce qui se passe sur le terrain, l'identification des acteurs et les changements survenus dans la sociĂ©tĂ© palestinienne. Quant au souci de nombre de commentateurs de prĂ©senter une version "Ă©quilibrĂ©e" de la situation ou de rendre justice Ă tel "camp", il ne fait souvent que rendre plus opaque la situation. Deux considĂ©rations principales ont donc guidĂ© la prĂ©paration de ce volume. La premiĂšre consistait Ă ĂȘtre conscient des contraintes de l'alĂ©atoire, du transitoire ou de l'urgence, de tout ce qui est liĂ© aussi Ă une certaine Ă©conomie de la violence dans la gestion des actions au quotidien. La seconde tenait Ă la nĂ©cessitĂ© de se livrer Ă une microsociologie de la sociĂ©tĂ© palestinienne. Les auteurs ont ainsi choisi d'aborder cette sociĂ©tĂ© en guerre par ce qui fait le quotidien des individus qui la composent. Ils s'Ă©loignent en cela des thĂšmes gĂ©nĂ©ralement valorisĂ©s par les mĂ©dias, tels que l'autoritĂ© contestĂ©e de Yasser Arafat, la rĂ©forme et la dĂ©mocratisation des institutions de l'AutoritĂ© palestinienne ou encore les rĂ©percussions de l'invasion amĂ©ricaine de l'Irak sur l'avenir des relations israĂ©lo-palestiniennes. D'une intifĂąda Ă l'autre vise Ă reflĂ©ter les prĂ©occupations, aspirations et difficultĂ©s concrĂštes de la population, Ă mettre en lumiĂšres les lectures palestiniennes de la rĂ©alitĂ© sociale
