Backward stochastic differential equations with unbounded generators

In this paper we consider two classes of backward stochastic differential equations. Firstly, under a Lipschitz-type condition on the generator of the equation, which can also be unbounded, we give sufficient conditions for the existence of a unique solution pair. The method of proof is that of Picard iterations and the resulting conditions are new. We also prove a comparison theorem. Secondly, under the linear growth and continuity assumptions on the possibly unbounded generator, we prove the existence of the solution pair. This class of equations is more general than the existing ones

Voronoi means, moving averages, and power series

We introduce a {\it non-regular} generalisation of the N\"{o}rlund mean, and show its equivalence with a certain moving average. The Abelian and Tauberian theorems establish relations with convergent sequences and certain power series. A strong law of large numbers is also proved

On some passions of autistic children: compensating functional language with technology (a semiotic prospective)

The present paper shall attempt to describe, analyze and elaborate some of the communicational deficits of the children with Autism Disorders Spectrum Syndrome (ASD), seen from the semiotic viewpoint. The focus shall be on the visual capacities, [such as described in: (Grandin, 2008)] of the children with Autism, as well as on their ability to compensate their brain dysfunctionalities through technology. In the mentioned context, semiotics should attempt at disclosing the meaning of their “own world”, to the extent of rendering it passionate. I shall intend by “passions” the repetitive requests, complaints, their emotionality etc., as intermediated by other tools (and/or media), that can be exemplified as one of the ways of “reducing” their sensory-motor deficits. In conclusion, the semiotics of passions, such as described by Greimas and Fontanille(1993) shall attempt deducing semantic units which are applicable for such children’s own “intended physiological context of behavior”. The results of “actions” performed by such individuals shall represent their own way of establishing a meta-communicative process. The deduced semantic units in terms of such children’s behavior are changeable, therefore an object to intersubjective processes of transformation

An Integrated Approach to the Conceptualisation and Measurement of Social Cohesion

The core sociological subject of ‘social cohesion’ (hereafter SC) has re-emerged as a key concept in the social sciences. On the one hand, SC is thought to be influenced by a society’s degree of inequalities and the quality of its welfare state. On the other hand, SC is thought to be instrumental in its own right to other factors such as economic growth, institutional quality, and individual well-being. In recent years, a few attempts have been made to measure SC empirically. Many current indices have not been sufficiently theoretically substantiated, and do not consider the importance of different ‘social levels’ when explaining and measuring SC as both cause and effect of other correlates. Very often, SC is simply defined as a ‘social quality’ or a quality of a collective. As a result, measures are often aggregate macro-indices leading to a loss of the information base of any social ‘units’ below the macro-societal-level. Contributing to this important methodological debate, this paper provides a conceptual reformulation of SC. Hence, when assessing SC based on a multi-dimensional index, it is insightful and feasible to evaluate both its internal variation as well as its holistic validity. In fact, it is proposed that these two aspects of measurement stand in direct relationship to one-another. The paper starts out with a discussion of SC as a ‘social fact’ in the Durkheimian sense. In addition, three bridging propositions on the measurement of SC are advanced: (a) SC as outcome or consequence at the level of individual attitudes and orientations (‘micro’); (b) SC as degree of dissimilarity and presence of latent conflict within a society at the level of salient social categories (‘meso’), and (c) SC as predictor, social determinant and hence antecedent at the societal-level (‘macro’). Using all rounds of the European Social Survey with a very large sample size, the advantages of this approach are illustrated by singling-out the important link between socio-economic inequalities, social cohesion and individual subjective well-being in a path of action

Divergent Cesàro Means of Jacobi-Sobolev Expansions

Let µ be the Jacobi measure supported on the interval [­1; 1]. Let introduce the Sobolev-type inner product …. In this paper we prove that, for certain indices δ, there are functions whose Ces_aro means of order δ in the Fourier expansion in terms of the orthonormal polynomials associated with the above Sobolev inner product are divergent almost everywhere on [-1; 1].Let µ be the Jacobi measure supported on the interval [­1; 1].

Achieving thermal comfort and sustainable urban development in accordance with the principles of bioclimatic architecture: A case study of Ulcinj (Montenegro)

Human communities have always taken actions to create a healthier environment for living and working. Those efforts are best documented in the architectural structure everywhere, starting from ancient history to the present. It is assumed that the town of Ulcinj is one of the earliest cities on the Adriatic coast. The building morphology and urban structure of Ulcinj is 2,500 years old and is continued by multi-ethnical society. Hence, the urban structure of Ulcinj developed harmonically across the rock hills which encompass the city beach, forming the urban structure which is perceived as the unity of land and sea. The study investigates the Ulcinj urban structure, urban management, sustainable development, focusing on human comfort, and environmental actions with a view to accomplish better and more natural life. Bioclimatic passive design principles are associated with an environmental sustainable design, interrelated to the microclimate of the region, connected to the thermal, spatial, visual, acoustic, and air quality. The research method consists of empirical observation through the city and riviera. According to the conceptual findings of this paper, with a proper implementation of bioclimatic passive principles, the work seeks to indicate that it is possible to achieve a higher level than the current one. Hence, the huge number of tourists and overnight stays can make a difference in eco-tourism, and sustainable development if we can achieve energy efficiency, and preserve the natural resources in accordance with passive bioclimatic principles
