La rencontre d'Assise de 1986 pour la paix dans le monde : préparatifs, déroulement et suites. Analyse praxéologique d'une pratique de dialogue interreligieux.

En 1986, à Assise, le pape Jean-Paul II a innové en rassemblant des chefs religieux du monde entier pour une prière pour la paix dans le monde. Ce mémoire s'attarde sur cette pratique particulière de dialogue interreligieux à Assise. L'analyse praxéologique de la rencontre d'Assise a permis, dans une première partie appelée observation, après une contextualisation de la rencontre, d'en suivre pas à pas les préparatifs et le déroulement pour terminer sur les suites d'Assise dans le monde. Cette observation nous a permis de soulever une problématique fondamentale à savoir comment l'Eglise peut-elle contribuer pleinement au dialogue interreligieux tout en conservant intactes son identité et sa mission? En d'autres termes, la rencontre d'Assise a-t-elle été une pratique de dialogue interreligieux en conformité avec les convictions de la foi chrétienne? Sur la base de notre problématique et dans une deuxième partie appelée interprétation, nous avons procédé à une analyse théologique de la rencontre d'Assise en regard de thèmes majeurs de la Christologie que sont la Révélation, le Salut, la Vérité et la missiologie. De cette interprétation découle, qu'à Assise, la Christologie catholique a été repensée dans un sens plus pneumatique et plus inclusif. A la lumière de notre interprétation théologique, et dans une troisième partie appelée intervention, nous sommes revenu sur ce qui nous semble être les points forts et les points faibles de la rencontre, avant d'élargir l'horizon sur des initiatives similaires au Québec en s'inspirant d'Assise. A cet effet, nous avons proposé que l'Oratoire Saint-Joseph qui, de par sa fréquentation multireligieuse et de par la fraternité qui s'y vit quotidiennement pourrait être le théâtre d'une rencontre interreligieuse inspirée d'Assise.

Instance generators and test suites for the multiobjective quadratic assignment problem

We describe, and make publicly available, two problem instance generators for a multiobjective version of the well-known quadratic assignment problem (QAP). The generators allow a number of instance parameters to be set, including those controlling epistasis and inter-objective correlations. Based on these generators, several initial test suites are provided and described. For each test instance we measure some global properties and, for the smallest ones, make some initial observations of the Pareto optimal sets/fronts. Our purpose in providing these tools is to facilitate the ongoing study of problem structure in multiobjective (combinatorial) optimization, and its effects on search landscape and algorithm performance.

The location of executive suites and business centers in the United States: an exploratory analysis

Increasingly, corporate occupiers seek more flexible ways of meeting their accommodation needs. One consequence of this process has been the growth of the executive suite, serviced office or business centre market. This paper, the final report of a research project funded by the Real Estate Research Institute, focuses upon the geographical distribution of business centers offering executive suites within the US. After a brief review of the development of the market, the paper examines the availability of data, provides basic descriptive statistics of the distribution of executive suites by state and by metropolitan statistical area and then attempts to model the distribution using demographic and socio-economic data at MSA level. The distribution reflects employment in key growth sectors and the position of the MSA in the urban hierarchy. An appendix presents a preliminary view of the global distribution of suites.

Behavioral suites mediate group-level foraging dynamics in communities of tropical stingless bees

Competition for floral resources is a key force shaping pollinator communities, particularly among social bees. The ability of social bees to recruit nestmates for group foraging is hypothesized to be a major factor in their ability to dominate rich resources such as mass-flowering trees. We tested the role of group foraging in attaining dominance by stingless bees, eusocial tropical pollinators that exhibit high diversity in foraging strategies. We provide the first experimental evidence that meliponine group foraging strategies, large colony sizes and aggressive behavior form a suite of traits that enable colonies to improve dominance of rich resources. Using a diverse assemblage of Brazilian stingless bee species and an array of artificial ""flowers"" that provided a sucrose reward, we compared species` dominance and visitation under unrestricted foraging conditions and with experimental removal of group-foraging species. Dominance does not vary with individual body size, but rather with foraging group size. Species that recruit larger numbers of nestmates (Scaptotrigona aff. depilis, Trigona hyalinata, Trigona spinipes) dominated both numerically (high local abundance) and behaviorally (controlling feeders). Removal of group-foraging species increased feeding opportunities for solitary foragers (Frieseomelitta varia, Melipona quadrifasciata and Nannotrigona testaceicornis). Trigona hyalinata always dominated under unrestricted conditions. When this species was removed, T. spinipes or S. aff. depilis controlled feeders and limited visitation by solitary-foraging species. Because bee foraging patterns determine plant pollination success, understanding the forces that shape these patterns is crucial to ensuring pollination of both crops and natural areas in the face of current pollinator declines.

Morphological and compositional variations of zircon and their metallogenetic implications: the example of the Jamon, Serra dos Carajás and Velho Guilherme suites, Amazonian Craton

Zircões de granitos das Suítes Jamon (SJ), Serra dos Carajás (SSC) e Velho Guilherme (SVG) foram estudados em MEV por meio de imagens de elétrons retroespalhados e catodoluminescência e análises pontuais por EDS. Granitos e greisens da SVG apresentam zircões dominantemente anédricos, alterados e intensamente corroídos, enriquecidos em Hf e com as mais baixas razões Zr/Hf, as quais nos granitos tendem a decrescer no sentido das fácies mais evoluídas. Zircões da SJ são euédricos a subédricos, zonados e pouco alterados, comparativamente empobrecidos em Hf e com as mais elevadas razões Zr/Hf, indicando potencial reduzido para geração de mineralização estanífera. Zircões dos granitos da SSC são subédricos a anédricos, alterados e corroídos e com conteúdos de Hf e razões Zr/Hf intermediárias a dos zircões das SJ e SVG. Granitos da SVG com mineralizações de Sn, W e Ta apresentam zircões com razões Zr/Hf entre 7 e 22. Conclui-se que razões desta ordem podem ser utilizadas como guia prospectivo de granitos especializados. Por outro lado, zircões de greisens associados ao Granito Cigano da SSC apresentaram razão Zr/Hf média em torno de 23, porém nenhuma cassiterita foi encontrada nessas rochas. Isto indica que estes zircões preservaram sua assinatura magmática original. O estudo desenvolvido permitiu distinguir as três suítes graníticas em termos de composição de zircão, e mostrou a importância da assinatura geoquímica desse mineral, sobretudo da razão Zr/Hf, na identificação de granitos especializados. Análises de zircões por MEV-EDS podem, portanto, ser utilizadas na avaliação preliminar do potencial metalogenético de granitos estaníferos.

MODEL PARTITIONS AND COMPACT TEST CASE SUITES

We present a generalized test case generation method, called the G method. Although inspired by the W method, the G method, in contrast, allows for test case suite generation even in the absence of characterization sets for the specification models. Instead, the G method relies on knowledge about the index of certain equivalences induced at the implementation models. We show that the W method can be derived from the G method as a particular case. Moreover, we discuss some naturally occurring infinite classes of FSM models over which the G method generates test suites that are exponentially more compact than those produced by the W method.

An arranged marriage for precision medicine: hypoxia and genomic assays in localized prostate cancer radiotherapy

Prostate cancer (CaP) is the most commonly diagnosed malignancy in males in the Western world with one in six males diagnosed in their lifetime. Current clinical prognostication groupings use pathologic Gleason score, pre-treatment prostatic-specific antigen and Union for International Cancer Control-TNM staging to place patients with localized CaP into low-, intermediate- and high-risk categories. These categories represent an increasing risk of biochemical failure and CaP-specific mortality rates, they also reflect the need for increasing treatment intensity and justification for increased side effects. In this article, we point out that 30-50% of patients will still fail image-guided radiotherapy or surgery despite the judicious use of clinical risk categories owing to interpatient heterogeneity in treatment response. To improve treatment individualization, better predictors of prognosis and radiotherapy treatment response are needed to triage patients to bespoke and intensified CaP treatment protocols. These should include the use of pre-treatment genomic tests based on DNA or RNA indices and/or assays that reflect cancer metabolism, such as hypoxia assays, to define patient-specific CaP progression and aggression. More importantly, it is argued that these novel prognostic assays could be even more useful if combined together to drive forward precision cancer medicine for localized CaP.
