Fischer’s approach for structure elucidation of linear aldohexoses is still the most widespread alternative in textbooks for carbohydrates. However, in post-Fischer era, a series of remarkable discoveries and inventions were made in different laboratories, and by their use a more comprehensive and coherent strategy for structure elucidation of linear isomeric aldohexoses can be elaborated. Fischer used the exceptional properties of d-mannose for the knowledge of configuration of C-2 and called it the key of the gate to stereochemistry. We bring the (...) evidence that Fischer had an alternative to this monosaccharide, d-idose. Fischer discovered the correct structure of the enantiomers of tartaric acid by pure intuition but Bijvoet proved it experimentally by means of X-rays. Hybridization, a concept taken by L. Pauling from biology, reconciled physics and chemistry concerning the valence of carbon atom and explained the stereochemical picture that had been empirically elaborated by Van’t Hoff and Le Bel. Other chemical transformations of monosaccharides, useful in the elucidation of their structure, have been also discovered or invented in post-Fischer era. (shrink)

Au XIXe siècle, il était plus facile de traverser l’Atlantique qu’il ne l’est aujourd’hui de traverser la Méditerranée. Si la traversée prenait davantage de temps, le prix du voyage et le nombre de migrants n’avaient rien de comparable avec l’actuelle traversée de la Méditerranée. En 1903 par exemple, plus de 12 000 migrants pouvaient arriver en une seule journée dans le seul port d’Ellis Island. Les migrants européens s’entassaient par milliers dans l’entrepont des bateaux payant l’équivalen..

Dans l’opinion publique, la migration « irrégulière » est associée à l’entrée et au séjour non autorisés. Un nombre croissant d’études indiquent toutefois qu’elle résulte de la production de catégories légales de séjour autorisé. Le présent chapitre enrichit cette littérature, en montrant comment la construction de la catégorie légale de travail autorisé est productrice d’immigration « irrégulière ». En effet, la multiplication des conditions d’accès à l’autorisation de travail a pour effet de priver de droit au séjour des personnes autrement (...) en situation régulière. La France, située en tête de classement en matière d’obligations de quitter le territoire et en fin de classement en matière d’immigration professionnelle, représente un cas d’école parmi les pays de l’Union Européenne.

En 2010, les femmes constituaient la majorité des migrants qualifiés présents dans 20 pays membres de l’OCDE. Comment expliquer l’absence d’intérêt pour le phénomène de « féminisation de la migration qualifiée » que ces statistiques permettent d’observer ? À l’inverse, comment comprendre l’engouement pour l’expression « féminisation de la migration » (tout court) alors que les données ne la confirment pas ? Pour répondre à ces questions, cet article analyse les usages de l’expression « féminisation de la migration » et (...) identifie son origine dans la théorie de la division internationale du travail. Centrée sur une critique de la mobilité du capital, cette théorie prédit une féminisation de la migration et l’associe aux emplois peu qualifiés. Cependant, les recherches qui s’en inspirent risquent de perdre de vue le diplôme de l’enseignement supérieur qui représente le véritable passeport pour les femmes originaires des pays en développement.

Cet article propose une évaluation éthique des institutions qui organisent la transplantation avec donneurs décédés, au travers du rôle qu’elles accordent à la famille survivante. Son objectif est double. Il s’agit, premièrement, de montrer que la famille possède un pouvoir de décision considérable en matière de prélèvement posthume bien que les législations soient habituellement décrites comme fondées sur le consentement ou l’opposition des personnes concernées. Deuxièmement, il s’agit de montrer que les politiques qui octroient un tel pouvoir aux familles manquent (...) à un devoir d’équité, en négligeant les intérêts à la fois des personnes concernées et des malades en attente de greffe.

The aim of this article is to show that refusing to legalize the status of undocumented immigrants who have been long-term residents is a serious violation of human rights. The "right to have rights" ­ a term coined by Hannah Arendt and developed by Sheila Benhabib ­ should be construed first and foremost as the right to a legal existence. We take issue with consequentialists who warn that legalizing the status of undocumented aliens will encourage further undesirable immigration, for withholding (...) legal status in order to deter illegal newcomers is neither efficacious nor just. We conclude that "selective" as opposed to "endured" immigration policies are ethically untenable. (shrink)

The international system of obligatory passports, as it exists today, was established at the beginning of the First World War. After the Armistice, the League of Nations tried to abolish it, but several governments delayed it. This article analyzes how the French press of the interwar period called for the abolition of passports. Seen as a "vexation", the passport was deemed "useless" after the war. So why wasn’t it abolished? Among the reasons for maintaining passports, we explore the hypothesis of (...) political “utility”: the regime of obligatory passports enabled governments to refuse passports and thus to control the transnational activity of political opponents.

« Utopique » se dit d’un projet irréalisable, qui ne saurait exister. Or, un monde où les passeports n’étaient pas obligatoires pour traverser une frontière a bel et bien existé : c’est celui d’avant la Première Guerre Mondiale. Cet article résume l'histoire des efforts pour abolir le régime des passeports obligatoires après la Première Guerre Mondiale.

Au regard du vieux débat sur la « fuite des cerveaux », le devoir de promouvoir le développement des pays pauvres semblait incompatible avec le droit humain à l’émigration. A l’encontre de cette idée, Jagdish Bhagwati a proposé dans les années 70 une mesure qui permettait au personnel qualifié de quitter les pays pauvres, tout en taxant leur revenu au bénéfice de leurs pays d’origine. Cet article discute (et rejette) trois justifications possibles de la taxe Bhagwati. Il conclut qu’une telle (...) mesure ne peut être défendue ni comme une compensation pour ce que le pays aurait gagné si les diplômés n’avaient pas émigré, ni comme une obligation de réciprocité basée sur l’investissement dans l’éducation, ni comme une mesure de diminution de l’inégalité entre les opportunités des migrants et de ceux qui restent au pays. Si la mobilité géographique va de pair avec la mobilité sociale, taxer les migrants revient à taxer la mobilité sociale, plutôt que les hauts revenus eux-mêmes. (shrink)

If migration is more effective than aid for fighting poverty, should it replace aid? Not always. This article proposes a criterion that may be used to distinguish between cases where migration should serve as a substitute for development assistance and cases where it should supplement such aid. According to this criterion, development agendas are poverty-efficient when they lift the largest possible number of people out of poverty. Therefore, to be poverty-efficient, development agendas should always aim to complement aid with policies (...) for pulling people out of poverty. Development assistance that is not poverty-efficient should be abandoned and replaced by migration and other policies that can effectively fight poverty. (shrink)

Les derniers écrits de John Rawls sont marqués à la fois par la reconnaissance du « fait du pluralisme » et par la défense d’une conception « politique » de justifica-tion publique, indépendante de considérations métaphysiques et épistémiques. Le but de cet article est de montrer que l’abstinence épistémique n’est ni une façon d’assurer le respect mutuel des citoyens, ni un moyen de diminuer le désaccord dans une société pluraliste. Faire de son mieux dans l’observance des normes épistémiques de la (...) justification est une façon certes indirecte, mais plus solide de faire montre du respect dû à autrui, en tant que personne capable non seulement de former sa conception du bien, mais aussi de la réviser.

In the present chapter I try to determine to what extent the public policies adopted by Romanian governments following the fall of the communist regime contributed to alleviating the most egregious past injustice, the Holocaust. The measures taken for memorializing the Holocaust will be analysed through the lens of a mixed reparatory justice – relational egalitarian account. Employing such a framework entails a focus on symbolic reparations, meant to promote civic trust, social solidarity, and encourage the restoration of social and (...) cultural capital in societies affected by historical injustices. Such symbolic reparations can include public atonement, changing street names, establishing memorials, funding museums, including Holocaust study in the national curriculum, setting national days for the commemoration of the Holocaust, etc. The need for symbolic reparation has become increasingly clearer in the literature on Holocaust memorialization, and the present paper intends to go a step further, by providing researchers with a theoretical approach that can be used to make better sense of the effects of measures taken as part of the process of Holocaust remembrance. In the chapter I also address the issue of determining who the duty-bearers should be. I argue that there could be several indicators for reparatory justice, including in this case compensation programs and the establishment of institutions that would allow dialogue between descendants of the victims and descendants of the perpetrators, a sine qua non condition for restoring social trust in communities marked by violations of human rights, especially of such a scale as the Holocaust.

In this paper we prove polyadic counterparts of the Hájek, Paris and Shepherdson's conservative extension theorems of Łukasiewicz predicate logic to rational Pavelka predicate logic. We also discuss the algebraic correspondents of the provability and truth degree for polyadic MV-algebras and prove a representation theorem similar to the one for polyadic Pavelka algebras.

Methodological nationalism is the assumption that nation-states are the relevant units for analyzing social phenomena. Most of the social sciences recognized it as a source of bias, but not the ethics of immigration. Is this field biased by methodological nationalism—and if so, to what extent? This article takes nationalism as an implicit bias and provides a method to assess its depth. The method consists in comparing principles that ethicists commonly discuss when immigration is not at stake with principles advocated in (...) the ethics of immigration. To interpret the results, a distinction between mild and heavy bias is established. When a basic principle in ethics is underdiscussed or absent from the ethics of immigration, the field is ‘mildly biased’. When its negation is commonly advocated, the field is ‘heavily biased’. Here, the method is illustrated with two principles: equal opportunity and reparation. They are common in theories of distributive justice and of corrective justice, respectively. But in the ethics of immigration, scholars often argue for the opposite. Instead of equal opportunity, they implicitly support discrimination based on national origin; instead of sanctions or amnesty for the offenders, scholars plead amnesty for those who they otherwise regard as victims. These preliminary results suggest that the field is heavily biased: methodological nationalism seems to turn ethics into its opposite. (shrink)

Migrant women are often stereotyped. Some scholars associate the feminization of migration with domestic work and criticize the “care drain” as a new form of imperialism that the First World imposes on the Third World. However, migrant women employed as domestic workers in Northern America and Europe represent only 2% of migrant women worldwide and cannot be seen as characterizing the “feminization of migration”. Why are migrant domestic workers overestimated? This paper explores two possible sources of bias. The first is (...) sampling: conclusions about “care drain” are often generalized from small samples of domestic workers. The second stems from the affect heuristic: imagining children left behind by migrant mothers provokes strong feelings of injustice which trump other considerations. The paper argues that neither source of bias is unavoidable and finds evidence of gender stereotypes in the “care drain” construal. (shrink)

Numerous groups race to discover the gene biomarker whose alteration alone is indicative of a particular disease in all humans. Biomarkers are selected from the most frequently altered genes in large population cohorts. However, thousands of other genes are simultaneously affected, and, in each person, the same disease results from a unique, never-repeatable combination of gene alterations. Therefore, our Genomic Fabric Paradigm (GFP) switches the focus from the alteration of one particular gene to the overall change in selected groups of (...) functionally related genes. Biomarkers are of little therapeutic value, their high alterability indicating low protection by the homeostatic mechanisms as for minor players. Instead of these most alterable genes in all patients, GFP identifies in each patient the genes whose highly protected expression governs major functional pathways by controlling the expression of numerous other genes. Smart manipulation of such (commander) genes would have the maximum therapeutic benefit not for everybody but for the treated person. The genomic fabric is defined as the transcriptome associated with the most interconnected and stably expressed network of genes responsible for a particular functional pathway. The fabric exhibits specificity with respect to race/strain, sex, age, tissue/cell type, and lifestyle and environmental factors. It remodels during development, progression of a disease, and in response to external stimuli. GFP is powered by mathematically advanced analytical tools whose application is illustrated by reprocessing data from previously published gene expression experiments. (shrink)
