Every triangle-free induced subgraph of the triangular lattice is(5m,2m)-choosable
2014
A graph G is (a,b)-choosable if for any color list of size a associated with each vertex, one can choose a subset of b colors such that adjacent vertices are colored with disjoint color sets. This paper proves that for any integer m>=1, every finite triangle-free induced subgraph of the triangular lattice is (5m,2m)-choosable.
The λ-Error Order in Multivariate Interpolation
2005
The aim of this article is to introduce and to study a generalization of the error order of interpolation, named λ – error order of interpolation. This generalization makes possible a deeper analysis of the error in the interpolation process. We derived the general form of the λ – error order of interpolation and then we applied it for many choices of the functional λ.
Groups whose prime graph on conjugacy class sizes has few complete vertices
2012
Abstract Let G be a finite group, and let Γ ( G ) denote the prime graph built on the set of conjugacy class sizes of G. In this paper, we consider the situation when Γ ( G ) has “few complete vertices”, and our aim is to investigate the influence of this property on the group structure of G. More precisely, assuming that there exists at most one vertex of Γ ( G ) that is adjacent to all the other vertices, we show that G is solvable with Fitting height at most 3 (the bound being the best possible). Moreover, if Γ ( G ) has no complete vertices, then G is a semidirect product of two abelian groups having coprime orders. Finally, we completely characterize the case when Γ ( G ) is a regular …
Exploring Neighborhood Influences on Small-Area Variations in Intimate Partner Violence Risk: A Bayesian Random-Effects Modeling Approach
2014
This paper uses spatial data of cases of intimate partner violence against women (IPVAW) to examine neighborhood-level influences on small-area variations in IPVAW risk in a police district of the city of Valencia (Spain). To analyze area variations in IPVAW risk and its association with neighborhood-level explanatory variables we use a Bayesian spatial random-effects modeling approach, as well as disease mapping methods to represent risk probabilities in each area. Analyses show that IPVAW cases are more likely in areas of high immigrant concentration, high public disorder and crime, and high physical disorder. Results also show a spatial component indicating remaining variability attribut…

Economic Value Added – A General Review of the Concept
2017
Business organizations of the 21st century, a century driven by globalization,internationalization and speed, must compete on changing and evolving markets. One of the maingoals of every business is to create value for its shareholders, value that is generated by the properusage of existing resources. The notion that can be utilized to successfully illustrate the increase ineconomic value is the economic value added concept.. The Economic Value Added concept knownalso as EVA is an add on to value, value based management and economic value.. EVA is a methodand a tool for quantification and measurement of the value created by a business organization.
Sapotrophical development of fusarium graminearum : respective role of different natural habitats of the fungus in the wheat infectious process in Bu…
2012
Fusarium Head Blight (FHB), mainly caused by the fungal species Fusarium graminearum, is one of the most important disease altering wheat crops in Burgundy. Moreover the plant-pathogen interaction leads to the production of mycotoxins potentially toxic for humans and animals.The only alternative to date to prevent the development of the disease is to control the saprotrophic development of F. graminearum in its natural habitat, i.e. weeds, soil and crops residues. Due to the trend of reduced tillage, special attention should be paid to the role of crop residues in the survival and development of F. graminearum.Two approaches were chosen to better understand the saprotrophic development of F…
Challenges of nation-branding for stimulation of Latvian exports
2017
Abstract The presented research aims to contribute to the conceptualisation of the nation-brand of Latvia with the purpose of stimulation of national export performance. The subject of the research is three aspects presumably challenging the branding of Latvia with reference to national export development. The investigated challenges are the barriers and opportunities for green-branding of Latvia; the absence of the generally accepted indication of the geographical identity of the Baltic region; and the contradictable popular image of Latvia as a cheap country. The research poses two research questions inquiring into the issues of nation-branding of Latvia currently being faced in the conte…
Participative Planning Processes in the Absence of the (Public) Space of Democracy
2010
Abstract This article aims to investigate the role, limits and opportunities of participation programmes in a local political context where consensus-building and inclusionary practices are not high priorities. A public housing neighbourhood in Palermo is used as a case study in order to critically highlight the ambiguous role that participative practices tend to play in fragile contexts. The case study also highlights the need for some preconditions for effective participatory practices in planning. These preconditions are focused on Arendt's notion of the ‘space of democracy’. Some concepts developed by Hannah Arendt will be used to explain the necessity of these preconditions, and their …
