L’imprécision des sources orales et écrites, l’éparpillement et la disparité de ces dernières, rendent difficile la connaissance des personnages de l’histoire des sociétés de culture orale. Le récit oral sur Fadhma n’Soumeur, dont la notoriété et l’impact sur la société kabyle sont incontestables, est plus proche de la légende que de l’histoire tandis que l’historiographie coloniale, ignorant les réalités du pays occupé, est marquée par des considérations politiques et passionnelles.

With a certain graphic interpretation in mind, we say that a function whose value at every point in its domain is a nonempty set of real numbers is an Abacus. It is shown that to every collection C of abaci there corresponds a logic, called an abacus logic, i.e., a certain set of propositions partially ordered by generalized implication. It is also shown that to every collection C of abaci there corresponds a theory JC in a classical propositional calculus such (...) that the abacus logic determined by C is isomorphic to the poset of JC. Two examples are given. In both examples abacus logic is a lattice in which there happens to be an operation of orthocomplementation. In the first example abacus logic turns out to be the Lindenbaum algebra of JC. In the second example abacus logic is a lattice isomorphic to the ortholattice of subspaces of a Hilbert space. Thus quantum logic can be regarded as an abacus logic. Without suggesting "hidden variables" it is finally shown that the Lindenbaum algebra of the theory in the second example is a subalgebra of the abacus logic B of the kind studied in example 1. It turns out that the "classical observables" associated with B and the "quantum observables" associated with quantum logic are not unrelated. The value of a classical observable contains, in coded form, information about the "uncertainty" of a quantum observable. This information is retrieved by decoding the value of the corresponding classical observable. (shrink)

In much the same way that it is possible to construct a model of hyperbolic geometry in the Euclidean plane, it is possible to model quantum logic within the classical propositional calculus.

The Monographs produced by the International Agency for Research on Cancer (IARC) apply rigorous procedures for the scientific review and evaluation of carcinogenic hazards by independent experts. The Preamble to the IARC Monographs, which outlines these procedures, was updated in 2019, following recommendations of a 2018 expert Advisory Group. This article presents the key features of the updated Preamble, a major milestone that will enable IARC to take advantage of recent scientific and procedural advances made during the 12 years since (...) the last Preamble amendments. The updated Preamble formalizes important developments already being pioneered in the Monographs Programme. These developments were taken forward in a clarified and strengthened process for identifying, reviewing, evaluating and integrating evidence to identify causes of human cancer. The advancements adopted include strengthening of systematic review methodologies; greater emphasis on mechanistic evidence, based on key characteristics of carcinogens; greater consideration of quality and informativeness in the critical evaluation of epidemiological studies, including their exposure assessment methods; improved harmonization of evaluation criteria for the different evidence streams; and a single-step process of integrating evidence on cancer in humans, cancer in experimental animals and mechanisms for reaching overall evaluations. In all, the updated Preamble underpins a stronger and more transparent method for the identification of carcinogenic hazards, the essential first step in cancer prevention. (shrink)

BackgroundBurnout is a recognized challenge among the oncology workforce. It affects both genders with a higher frequency among women. This study examined the factors contributing to the development of burnout among female oncologists from the Middle East and North Africa.MethodsAn online cross-sectional survey was distributed to oncology professionals from different countries in the MENA region. The validated Maslach Burnout Inventory of emotional exhaustion, Depersonalization, and Personal Achievement plus questions about demography/work-related factors and attitudes toward oncology were included. Data were analyzed (...) to measure BO prevalence and related factors.ResultsBetween 10 February and 15 March 2020, 545 responses were submitted by female oncologists. The responses pre-dated the COVID-19 pandemic emergence in the region. BO prevalence was 71% among female professionals. Women aged 25% on administrative work daily. Nearly half of the respondents expressed a recurring thought of quitting oncology and 70% had no burnout support or education. Inability to deliver optimal care was reported as distressing for career development in 82%. Factors significantly influencing the BO risk were identified. Marital status, having children, academia and years in practice did not impact the risk of BO among female oncologists from MENA.ConclusionFemale oncologists from the Middle East and North Africa were found to have a high prevalence of BO. In this cohort, the majority of women oncology workers were young and in their early to mid-career stages. Burnout was linked to being younger, practicing in North African nations, having a heavy administrative load, and having persistent thoughts of quitting. Practicing a hobby and engaging in oncology communication, on the other hand, reduced the chance of BO. Burnout support and education, specifically for oncology women, is required. (shrink)

The 21st century faces one of the most singular challenges of all times. How to react to the obstacles that follow the cycle of the Anthropocene, with all its disastrous and putrid consequences? There are two possible ways: acceptance of the situation or the critical and prophetic reaction, that lies on the ground of hospitality and dialogue. When ethnocentrism, xenophobia and fundamentalism grow, dialogue and acceptance of the other urge with a special meaning. Dialogue and Hospitality are expressions that interact (...) and complement each other. Facing the current situation that is asking for interconnection, we must broaden the fabrics of this reception, including not only human beings, but opening the scope to a wider dimension of all creation. Humankind is related, is linked to a larger web that weaves the universe. Inhabiting the Earth gains a new meaning, to be part of life itself. (shrink)

Este artigo visa esclarecer a relação entre a lógica formal e a lógica especulativa. Esta relação é tal que entre os dois tipos de lógica há um desenvolvimento interno na direção de uma única noção, ou seja, a de forma lógica. Tomarei como ponto de partida a análise da lógica de Wolff e mostrarei que esta é já uma lógica que vai além do sentido meramente formalista dessa disciplina, na medida em que está já voltada para a objetividade. Na viragem (...) transcendental kantiana há, por sua vez, uma tentativa de passar das determinações conceituais abstratas para o desenvolvimento de determinações orientadas para os objetos de conhecimento e, assim, para o conteúdo do próprio conhecimento. Finalmente, o projeto lógico hegeliano é tal que não implica a saída das malhas da rede conceitual da lógica formal e transcendental, mas a investigação dessas malhas de modo a delinear a estrutura interna de cada um dos nós da rede. Mais especificamente, Hegel pretende desenvolver uma noção de forma lógica que não mais é limitada e dependente de um conteúdo externo a ela, porque é uma forma absoluta, ou seja, uma forma capaz de gerar o seu próprio conteúdo através do desenvolvimento da sua dialética imanente.

Baseado nos pressupostos teórico-metodológicos da Análise de Discurso Francesa, este trabalho visa a investigar os depoimentos de mulheres paraplégicas que residem no Distrito Federal , tendo por base seus discursos sobre sexualidade, corpo e deficiência. O debate propiciou-me verificar que quando afetadas pela malha discursiva do outro é que essas mulheres constroem suas representações sobre sexualidade, corpo e deficiência.Anchored to the theoretical basis of the French Discourse Analysis , this work aims to investigate the depositions from some paraplegic women (...) residing in Distrito Federal , based on their discourse on sexuality, body and disability. The data analysis allowed me to verify that when affected by the discourse of others these women build their concepts of/about sexuality, body and disability. (shrink)

A espiritualidade é o cuidado com a vida em sua integralidade. Como define Faustino Teixeira no artigo “Malhas da hospitalidade”, ela é a _capacidade de celebrar a vida em profundidade_, ou seja, a capacidade humana de reconhecer que a vida tem uma dimensão profunda – da qual irradiam amor desinteressado, gratuidade, atenção, cortesia e hospitalidade – e de se alegrar com isso. Diferentemente do que geralmente se pensa, a espiritualidade não se restringe aos templos e espaços religiosos, antes, diz respeito (...) a pessoas e não a almas etéreas. Portanto, perpassa toda a vida cotidiana. Na atualidade, diante dos desafios dos tempos sombrios em que vivemos, tanto na dimensão política como na de saúde pública, a casa se torna um lugar privilegiado para o cultivo da espiritualidade. Neste artigo, buscamos explicitar a dimensão espiritual da comensalidade de acordo com uma análise interpretativa do filme “A Festa de Babette” (1987), dirigido por Gabriel Axel, baseado na obra homônima da escritora dinamarquesa Karen Blixen. Em nossa análise, buscamos ressaltar a compreensão ecumênica do mistério eucarístico que o filme inspira. (shrink)
