Un bilinguisme stable est-il possible à Iqaluit?

Many speakers of the Inuit language in Iqaluit (Nunavut) wish for an evolution of the current linguistic situation towards an ideal situation of stable bilingualism. However, efforts at promoting the Inuit language do not clearly challenge the dynamics of language loss in the capital of the territory. An inquiry about the role of literacy in the search for stable bilingualism allows for a better understanding of language choices among bilingual speakers. The attitudes of the speakers show that in order to strengthen intergenerational transmission one must take into account a tendency to marginalise Inuit language literacy in daily life.De nombreux locuteurs de la langue inuit à Iqaluit (Nunavut) expriment le désir que la situation linguistique évolue idéalement vers un bilinguisme stable. Néanmoins, les efforts de promotion de la langue inuit n’infléchissent pas nettement la dynamique de perte de la langue dans la capitale du territoire. Étudier le rôle de l’écriture dans la recherche de ce bilinguisme stable permet une meilleure compréhension des choix langagiers chez les locuteurs bilingues. Les attitudes des locuteurs montrent que pour consolider la transmission intergénérationnelle il faut prendre en compte une tendance à la marginalisation de l’écrit en langue inuit au quotidien

Hot Streaks in Artistic, Cultural, and Scientific Careers

The hot streak, loosely defined as winning begets more winnings, highlights a specific period during which an individual's performance is substantially higher than her typical performance. While widely debated in sports, gambling, and financial markets over the past several decades, little is known if hot streaks apply to individual careers. Here, building on rich literature on lifecycle of creativity, we collected large-scale career histories of individual artists, movie directors and scientists, tracing the artworks, movies, and scientific publications they produced. We find that, across all three domains, hit works within a career show a high degree of temporal regularity, each career being characterized by bursts of high-impact works occurring in sequence. We demonstrate that these observations can be explained by a simple hot-streak model we developed, allowing us to probe quantitatively the hot streak phenomenon governing individual careers, which we find to be remarkably universal across diverse domains we analyzed: The hot streaks are ubiquitous yet unique across different careers. While the vast majority of individuals have at least one hot streak, hot streaks are most likely to occur only once. The hot streak emerges randomly within an individual's sequence of works, is temporally localized, and is unassociated with any detectable change in productivity. We show that, since works produced during hot streaks garner significantly more impact, the uncovered hot streaks fundamentally drives the collective impact of an individual, ignoring which leads us to systematically over- or under-estimate the future impact of a career. These results not only deepen our quantitative understanding of patterns governing individual ingenuity and success, they may also have implications for decisions and policies involving predicting and nurturing individuals with lasting impact

Physical modelling of amorphous thermoplastic polymer and numerical simulation of micro hot embossing process

Micro hot embossing process is considered as one of the most promising micro replication processes for manufacturing of polymeric components, especially for the high aspect ratio components and large surface structural components. A large number of hot embossing experimental results have been published, the material modelling and processes simulation to improve the quality of micro replication by hot embossing process are still lacking. This paper consists to 3D modelling of micro hot embossing process with amorphous thermoplastic polymers, including the mechanical characterisation of polymers properties, identification of the viscoelastic behaviour law of the polymers, numerical simulation and experimental investigation of micro hot embossing process. Static compression creep tests have been carried out to investigate the selected polymers’ viscoelastic properties. The Generalized Maxwell model has been proposed to describe the relaxation modulus of the polymers and good agreement has been observed. The numerical simulation of the hot embossing process in 3D has been achieved by taking into account the viscoelastic behaviour of the polymers. The microfluidic devices with the thickness of 2 mm have been elaborated by hot embossing process. The hot embossing process has been carried out using horizontal injection/compression moulding equipment, especially developed for this study. A complete compression mould tool, equipped with the heating system, the cooling system, the ejection system and the vacuum system, has been designed and elaborated in our research. Polymer-based microfluidic devices have been successfully replicated by the hot embossing process using the compression system developed. Proper agreement between the numerical simulation and the experimental elaboration has been observed. It shows strong possibility for the development of the 3D numerical model to optimize the micro hot embossing process in the future

Substantiation Of Hot Smoking Parameters Based On Sensory Researches In Hot Fish Marinades Technology In The Jelly Pouring

Modern technologies of food products provide creation of healthy, tasty and safe products, characterized by high organoleptic properties, balance by main food factors and structural-mechanical parameters of a product.The main technological process in the technology of fish marinades and a jelly pouring is the hot smoking. Technological parameters of the hot smoking have been scientifically grounded on the base of the statistical processing of data of sensory studies. Organoleptic assessment of semi-products after the thermal processing was carried out by 5-point system corresponding to the elaborated scale. The quantitative assessment of organoleptic parameters of the quality of experimental samples was determined by the totality of all assessment points, taking into account chosen weight coefficients depending on the importance degree of a given parameter at forming consumer qualities of a product. The generalizing quality parameter was calculated as a sum of assessments of organoleptic parameters – taste, consistence and appearance. Individual assessments of separated quality parameters of products (in points) were put in degustation lists and statistically processed by the averaging method.The smoking process realization, according to scientifically grounded parameters allows to produce the new type of tasty, healthy and presentable culinary products of a perspective object of Ukrainian aquaculture – silver carp of a prolonged storage term

A Hot Channel

This paper studies on-chip communication with non-ideal heat sinks. A channel model is proposed where the variance of the additive noise depends on the weighted sum of the past channel input powers. It is shown that, depending on the weights, the capacity can be either bounded or unbounded in the input power. A necessary condition and a sufficient condition for the capacity to be bounded are presented.Comment: to be presented at 2007 IEEE Information Theory Workshop (ITW), replaced with version that will appear in the proceeding
