Cut-elimination, substitution and normalisation
No full textDate of Acceptance: 01/2015We present a proof (of the main parts of which there is a formal version, checked with the Isabelle proof assistant) that, for a G3-style calculus covering all of intuitionistic zero-order logic, with an associated term calculus, and with a particular strongly normalising and confluent system of cut-reduction rules, every reduction step has, as its natural deduction translation, a sequence of zero or more reduction steps (detour reductions, permutation reductions or simplifications). This complements and (we believe) clarifies earlier work by (e.g.) Zucker and Pottinger on a question raised in 1971 by Kreisel.Peer reviewe
I remember teaching English at Seabrook
No full textIn this "I remember" memoir, Isabell Waugh, a former teacher at Seabrook, compares and constrasts the different groups of students she taught. She remembers that native-born American teenagers tended to be more concerned with athletics and social activities, than academic matters. In comparison, Estonian and Japanese parents did not tolerate low academic performance, so students from the two groups often competed intensely with each other for academic achievement and recognition. Isabelle recalls that the Estonians were, in general, more sophisticated and better educated. Most of the children knew 3-5 languages, and were more advanced in math and science. She sensed that some Estonian parents felt that their homes at Seabrook were temporary, and that they would be returning to Estonia at some point. The Seabrook Educational and Cultural Center has been soliciting current and past residents of Seabrook Farms for an "I remember" project. Residents are asked to create narratives regarding their experiences at Seabrook Farms. These memories help preserve the history and multi-cultural heritage of Seabrook Farms
Isabelle Bell to Susan Niemcewicz, December 23, 1800
No full textIsabelle Bell wrote to Susan U. Niemcewicz in Elizabethtown, New Jersey. Bell expressed her disappointment in not receiving a line from Susan. She sent Bell Lucretia Rephans subscription epistle, but Susan refrained from writing a letter to her. Bell did not execute any of Susan’s commissions in New York because her time there was short. Miss Resham heard that Mr. B Livingston told his sister, Mrs. J. Livingston that he would offer Bell a salary to live in his house and take charge of his children’s education. Asked if Susan what she thought of her being an author and if Susan would subscribe to a small volume that may have the good fortune to rival the poems of the immortal Scarron.https://digitalcommons.kean.edu/lhc_1800s/1143/thumbnail.jp

Formalization of Isabelle Meta Logic in NuPRL
No full textNuPRL and Isabelle are two general purpose theorem provers. Both of them are based on a version of Constructive Higher Order Type Theory. In an earlier work the author has proposed an informal semantics of Isabelle Meta Logic in an extension of NuPRL Type Theory. An automated converter, based on this semantics, has been developed, that translates Isabelle theorem statements into NuPRL. This work presents a formalization of the above semantics in NuPRL. It starts with a deep embedding of Isabelle type and term syntax into NuPRL Constructive Type Theory. Next, two internal NuPRL functions are defined. One of them maps Isabelle types into NuPRL types and the other maps Isabelle terms into elements of appropriate NuPRL types. These two functions provide an interpretation of Isabelle in NuPRL. Finally, interpretations of all Isabelle Meta Logic rules are proven as theorems in some classical extension of NuPRL Type Theory. This formalization is aimed to provide a more secure foundation for the interaction between two systems
L’analyse intersectionnelle du continuum des violences en situation de refuge : les discriminations en emploi
No full textDepuis les dernières décennies, les migrations internationales sont marquées par un phénomène de féminisation. Ce dernier doit être analysé dans une perspective féministe pour comprendre les structures sociales qui favorisent ou limitent la mobilité des femmes. En effet, les rapports sociaux inégalitaires complexifient les parcours migratoires et sont à l’origine de plusieurs formes de violences. Pour les comprendre, il faut se pencher sur les discriminations, les inégalités et les stéréotypes, notamment genrés, qui incitent souvent à la naturalisation de la violence et à l’assujettissement des femmes dans leur société d’origine, dans leur expérience du passage des frontières, et une fois arrivées en sol étranger. Pour saisir ces dynamiques, l’auteure, qui présente sa recherche sur les trajectoires migratoires de Colombiennes en situation de refuge en Équateur, s’est appuyée sur un cadre théorique alliant les théories féministes et le concept de continuum des violences. Ce cadre d’analyse a été mis en oeuvre dans une démarche qualitative qui a fait appel à la théorie de la connaissance située et qui est notamment basé sur des récits de vie. L’analyse de ces récits, recueillis auprès des personnes qui ont fait une demande d’asile ou qui sont en situation de refuge, a mis en évidence l’importance des discriminations qu’elles vivent en emploi. L’auteure propose donc une analyse de la façon dont l’enchevêtrement des différents systèmes d’oppression participe à l’exacerbation des violences dans le domaine spécifique du travail. En illustrant la manière dont les rapports inégalitaires qui se manifestent durant la migration influent sur l’accès au travail, le cantonnement dans des emplois historiquement féminins, précaires et dévalorisés, sans oublier l’exposition à différentes formes de violences; cet article permet de pousser plus loin les connaissances actuelles en proposant une réflexion globale sur les violences genrées dans les trajectoires migratoires.Since the last decades, international migration is marked by a phenomenon of feminization. The latter must be analyzed from a feminist perspective in order to understand the social structures that promote or limit the mobility of women. Unequal social relations hinder the migration pathways and are at the root of several forms of violence. In order to understand them, we must focus on discrimination, inequality and stereotypes, particularly gendered ones, which often incite the naturalization of violence and the subjugation of women in their societies of origin, in their experience of border crossing, as well as the arrival in foreign soil. To seize these dynamics, the author, presenting her research on the migratory trajectories of Colombian women in a situation of refuge in Ecuador, relied on a theoretical framework combining feminist theories and the concept of continuum of violence. This framework of analysis has been implemented through a qualitative research based on the standpoint theory approach and the documentation of life stories. The analysis of these stories, collected from asylum seekers and refugees, highlighted the importance of the discrimination they face in employment. The author therefore proposes an analysis of how the entanglement of the different systems of oppression contributes to the exacerbation of violence in the specific field of work. By illustrating how the unequal relationships that occur during migration influence access to work, cantonment in historically feminine, precarious and devalued jobs, as well as exposure to different forms of violence; this article contributes to the knowledge in this field of research by proposing a global reflection on the gendered violence in the migratory trajectories.Las migraciones internacionales están marcadas por un fenómeno de feminización. Este último debe analizarse desde una perspectiva feminista para comprender las estructuras sociales que favorecen o limitan la movilidad de las mujeres. Las relaciones sociales desiguales complican los patrones migratorios y de ellas provienen muchas formas de violencia. Para comprenderlas, es necesario insistir en las discriminaciones, desigualdades y estereotipos, especialmente los de género, que a menudo incitan a la naturalización de la violencia y a la subyugación de las mujeres en su sociedad de origen, en su experiencia de cruzar fronteras. así como una vez que llegó a tierra extranjera. Para capturar estas dinámicas, la investigación presentada aquí sobre las trayectorias migratorias de las Colombianas en situaciones de refugio en Ecuador se basó en un marco teórico que combina las teorías feministas y el concepto del continuums de las violencias. Este marco de análisis se implementó en un enfoque cualitativo que apelaba a la teoría del conocimiento localizado y que se basaba en particular en relatos de vida. El análisis de estos relatos, recogidos de solicitantes de asilo y de refugiadas, destacó la importancia de la discriminación que experimentan en el empleo. Por lo tanto, este artículo propone un análisis de cómo el entrelazamiento de los diferentes sistemas de opresión contribuye a la exacerbación de la violencia en el campo específico del trabajo. Al ilustrar cómo las relaciones desiguales que ocurren durante la migración influyen en el acceso al trabajo, el confinamiento en empleos históricamente femeninos, precarios y devaluados, así como en la exposición a diferentes formas de violencia, este artículo nos permite llevar el conocimiento ya disponible más allá al proponer una reflexión global sobre las violencias de género en las trayectorias migratorias
Security modeling and correctness proof using Specware and Isabelle
No full textSecurity modeling is the foundation to formal verification which is a core requirement for high assurance systems. This thesis explores how security models can be built in a simple and expressive manner using the Metaslang specification language in Specware. The models are subsequently translated, via the Specware to Isabelle Interface, to be proven for correctness in Isabelle which is a generic, interactive theorem proving environment. It is found that the translation between Specware and Isabelle is almost seamless and there is much potential in the use of Isabelle/HOL to discharge proof obligations that arise in developing Specware specifications, although the actual proving requires substantial knowledge and experience in logical calculus.Approved for public release; distribution is unlimited.Outstanding ThesisSingapore ST Electronics Ltd. author (civilian).http://archive.org/details/securitymodeling10945383
Empowerment et Économie sociale et solidaire (ÉSS) pour une transformation sociale en milieu rural malien : cas des centres d'autopromotion des femmes (CAFE) de Kita, Toubacoro et Dioïla
No full textL'empowerment est considéré comme un processus qui favorise le développement de pouvoirs par des personnes qui en sont dépourvues. Il constitue aussi un levier intéressant de réduction des inégalités entre les groupes sociaux. Il passe par une multitude de moyens et stratégies qui dépendent des réalités de vie des personnes concernées. Diverses recherches ont montré que l'économie sociale et solidaire (ÉSS) est un puissant levier par lequel les actions d'empowerment se concrétisent de manière durable puisqu'elle permet aux personnes en situation de vulnérabilité d'unir leurs forces et de faire les changements profonds nécessaires pour une justice sociale. Au Mali, les inégalités entre les hommes et les femmes sont importantes et elles s'amplifient depuis quelques années avec la pauvreté qui sévit dans les milieux de vie des populations. Pour réduire ces inégalités, le gouvernement appuyé par ses partenaires internationaux opte pour un empowerment des femmes, centré sur leur autonomisation économique. Pour ce faire, de nombreuses actions sont développées avec des organisations de femmes. Les centres d'autopromotion des femmes (CAFE) sont les moyens par lesquels l'empowerment des femmes des milieux ruraux maliens est soutenu, et ce, à travers leur autonomisation économique. Les CAFE réunissent les organisations des femmes qui relèvent du domaine de l'ÉSS notamment les associations et les coopératives et leur gestion est assuré par les regroupements que les responsables de ces organisations forment. Une recherche réalisée en 2017 a montré que les CAFE favorisent bien cette autonomisation économique et permettent aux femmes qui en sont membres de construire une certaine force collective. En revanche, les CAFE ne permettent pas aux femmes de développer des capacités de transformation des normes sociales qui donnent le pouvoir aux hommes et fait d'eux les dominants dans les sphères sociale, économique et politique. Notre thèse s'intéresse à cet apparent paradoxe en cherchant à répondre à la question suivante : empowerment des femmes rurales et économie sociale et solidaire : quels enjeux pour le développement de la capacité de transformation sociale au travers de centres d'autopromotion des femmes au Mali ? Pour aborder cette question, nous nous intéressons plus particulièrement à l'une des dimensions de l'empowerment : le « pouvoir intérieur ». Notre recherche s'est déroulée auprès des femmes de trois CAFE situés en milieu rural malien : Kita, Toubacoro et Dioïla. Elle prend appui sur une posture féministe postcoloniale qui met les femmes concernées et leurs points de vue au cœur de la recherche. Elle reconnait que les femmes ne sont pas une population homogène et que divers rapports de pouvoir existent entre elles. Par conséquent, elle utilise une approche intersectionnelle non seulement pour tenir compte de cette diversité de pouvoirs mais aussi pour rendre compte de l'interconnexion du sexisme et de l'âgisme dans les sphères sociale, économique et politique. En plus de la forte internalisation de la domination masculine par les femmes des CAFE, les résultats montrent qu'elles sont des actrices importantes de la perpétuation de la domination masculine. Les résultats montrent aussi que si le développement du « pouvoir intérieur » est indispensable pour l'empowerment des femmes, il ne demeure pas une priorité pour les CAFE et leurs organisations.Empowerment is seen as a process that promotes the development of power by people who lack it. It is also an interesting lever for reducing inequalities between social strata. It goes through a multitude of means and strategies which depend on the realities of life of the people concerned. Various research has shown that the social and solidarity economy (SSE) is a powerful lever through which empowerment actions take shape in a sustainable manner since it allows people in vulnerable situations to join forces and make changes. profoundly necessary for social justice. In Mali, the inequalities between men and women are significant and they have been amplified in recent years with the poverty that has raged in the living environments of the populations. To reduce these inequalities, the government, supported by its international partners, opts for the empowerment of women, centered on their economic empowerment. To do this, many actions have been developed with women's organizations. Women's Self-Promotion Centers (CAFE) are the means by which the empowerment of rural Malian women is supported, through their economic empowerment. CAFE bring together women's organizations in the field of SSE, particularly associations and cooperatives, and their management is carried out by the groups formed by the heads of these organizations. Research carried out in 2017 showed that CAFE do well to promote this economic empowerment and allow women who are members to build a certain collective strength. In contrast, CAFE do not allow women to develop the capacity to transform social norms that empower men and make them dominant in the social, economic and political spheres. Our thesis focuses on this apparent paradox by seeking to answer the following question: empowerment of rural women and the social and solidarity economy: what are the challenges for the development of the capacity for social transformation through women's self-promotion centers in Mali? ? To address this question, we are particularly interested in one of the dimensions of empowerment: "power within". Our research was carried out with the women of three CAFE located in rural Mali: Kita, Toubacoro and Dioïla. It is based on a postcolonial feminist posture which places the women concerned and their points of view at the heart of research. She recognizes that women are not a homogeneous population and that various power relationships exist between them. Therefore, she uses an intersectional approach not only to account for this diversity of powers but also to account for the interconnectedness of sexism and ageism in the social, economic and political spheres. In addition to the strong internalization of male domination by CAFE women, the results show that they are important actors in the perpetuation of male domination. The results also show that while the development of "power within" is essential for the empowerment of women, it does not remain a priority for CAFE and their organizations
Isabelle/DOF: Design and Implementation
No full textThis is the author accepted manuscript. The final version is available from Springer Verlag via the DOI in this record17th International Conference, SEFM 2019
Oslo, Norway, September 18–20, 2019DOF is a novel framework for defining ontologies and enforcing them during document development and evolution. A major goal of DOF is the integrated development of formal certification documents (e. g., for Common Criteria or CENELEC 50128) that require consistency across both formal and informal arguments. To support a consistent development of formal and informal parts of a document, we provide Isabelle/DOF, an implementation of DOF on top of the formal methods framework Isabelle/HOL. A particular emphasis is put on a deep integration into Isabelleâs IDE, which allows for smooth ontology development as well as immediate ontological feedback during the editing of a document. In this paper, we give an in-depth presentation of the design concepts of DOFâs Ontology Definition Language (ODL) and key aspects of the technology of its implementation. Isabelle/DOF is the first ontology language supporting machine-checked links between the formal and informal parts in an LCF-style interactive theorem proving environment. Sufficiently annotated, large documents can easily be developed collabo- ratively, while ensuring their consistency, and the impact of changes (in the formal and the semi-formal content) is tracked automatically.IRT SystemX, Paris-Saclay, Franc
La construction d'un monde professionnel : entrées des jeunes praticiens dans la médecine générale
No full textIsabelle Baszanger
The young general practitioners in the medical field.
Using interviews with young medical doctors (general practitioners) the author studies the ways they organize their empirical practice (as opposed to theoretical knowledge) and constructs a typology which caracterizes specific modes of professionnal socialization. This leads the author to evaluate the social dimensions of the role of general practitioners.La socialisation professionnelle des étudiants en médecine implique la formation d'un univers conceptuel qui est une sorte de compromis entre le savoir médical et la pratique quotidienne. A partir d'entretiens avec de jeunes médecins généralistes l'auteur a étudié comment les jeunes médecins organisent leur pratique et construit une typologie reflétant ces mécanismes particuliers de socialisation.
Cette analyse conduit l'auteur à s'interroger sur la dimension sociale du rôle du médecin généraliste telle qu'il la perçoit.Baszanger Isabelle.
