On Weakly Locally Uniformly Rotund Banach Spaces

1999

Abstract We show that every normed space E with a weakly locally uniformly rotund norm has an equivalent locally uniformly rotund norm. After obtaining a σ -discrete network of the unit sphere S E for the weak topology we deduce that the space E must have a countable cover by sets of small local diameter, which in turn implies the renorming conclusion. This solves a question posed by Deville, Godefroy, Haydon, and Zizler. For a weakly uniformly rotund norm we prove that the unit sphere is always metrizable for the weak topology despite the fact that it may not have the Kadec property. Moreover, Banach spaces having a countable cover by sets of small local diameter coincide with the descript…

An In Vitro Stereomicroscopic Evaluation of Bioactivity between Neo MTA Plus, Pro Root MTA, BIODENTINE & Glass Ionomer Cement Using Dye Penetrati…

2021

The ideal root end filling material should form a tight seal in the root canal by adhering to the cavity walls. Several materials have been used for root end filling. The present study aims to find out and compare the bioactivity of Neo MTA Plus, Pro Root MTA White, BIODENTINE & glass ionomer cement as root end filling materials using 1% methylene blue as tracer. Materials and methods: 80 extracted human permanent maxillary anterior teeth were used in the study. They were divided into four groups. Specimens were sectioned transversely in the cervical area to separate the crown from the root. The root canal was obturated with gutta percha and zinc oxide eugenol sealers. Thereafter, each …

Retail Evolution in Eastern European Countries: An Overview

2020

Retail has evolved a lot in the last years. Still, compared to more mature markets (such as US, UK, Germany, France, Sweden, the Netherlands), retail in Eastern European countries is less developed, with more balanced supply and demand. According to GfK’s report on European Retail in 2018, in 2017 there was a slight increase (+1.9 percent) in the purchasing power within the European Union (EU28) countries, Romania having the biggest increase (+7.8 percent) [1]. However, Romania’s low per capita purchasing power shows a gap in wealth levels across Europe. Huge differences between Western and Eastern Europe are visible also in terms of per capita values for retail space. Thus, the purpose of …

Tourism SME sustainability social and economic challenges during pandemic: cases of Russian Federation, Georgia and Latvia

2021

Until 2020, the tourism industry was characterized by a growth rate, the statistics highlight that globally 2019 was the tenth year with a consecutive annual growth. However, the Covid-19 pandemic marked a major turning point in the development of tourism, instead of tourism overdevelopment, the underdevelopment issues appeared in front pages of the industry news. The effects of the pandemic are intensified by the fact that tourism is a labour-intensive industry and that most companies in the sector are SMEs (small and medium sized enterprises). At this time, it is crucially important to look at sustainability issues, therefore the aim of this study is to analyse the social and economic dim…

Evaluation of the perceived social impacts of the Formula E Grand Prix of Santiago de Chile David

2020

[Abstract] The aim of this study is to analyse residents' perception of the social impact of the Formula E Grand Prix of Santiago de Chile. A sample of 414 residents was collected through a questionnaire made up of 46 items regarding possible positive and negative impacts. Descriptive analysis, confirmatory factorial analysis and cluster analysis were performed. The results showed two groups with different perceptions of this sporting event: realistic (n=152) and favourable (n=162). Sociodemographic variables referring to education level, civil status, income level, location of the family residence and political orientation contribute to significantly differentiating the clusters. The varia…

When the neighborhood educates: situated learning and collaborative artistic creation as a tool in the musical formation of the future teacher

2020

RESUMEN: Este estudio describe y analiza una acción artístico-pedagógica en el ámbito de la formación inicial de docentes y desarrollada en un barrio desfavorecido de Palma de Mallorca, España. Participaron 65 estudiantes del Grado de Maestro de Educación Primaria en la asignatura de Música y 3 músicos expertos, responsables de diseñar e implementar la acción. A través de una metodología cualitativa de tipo descriptivo-interpretativo, los resultados muestran: 1) algunas características que determinaron el diseño de la acción como son el aprendizaje situado, la colaboración, la creatividad y el compromiso con la realidad social del barrio; y 2) aspectos emergentes a partir de las valoracione…

A two-scale approach to electron correlation in multiconfigurational perturbation theory.

2014

We present a new approach for the calculation of dynamic electron correlation effects in large molecular systems using multiconfigurational second-order perturbation theory (CASPT2). The method is restricted to cases where partitioning of the molecular system into an active site and an environment is meaningful. Only dynamic correlation effects derived from orbitals extending over the active site are included at the CASPT2 level of theory, whereas the correlation effects of the environment are retrieved at lower computational costs. For sufficiently large systems, the small errors introduced by this approximation are contrasted by the substantial savings in both storage and computational de…

Viral marketing through e-mail: the link company-consumer

2013

Purpose – The purpose of this paper is to identify the antecedents that may determine the opening of e-mails from companies that endeavour to promote their products, and what may motivate individuals to forward such messages to others. Design/methodology/approach – The paper presents exploratory research to approach the nature of the viral process and descriptive research for testing the proposed hypotheses. Findings – The opening of an e-mail is determined by the value that an individual may perceive that the message might contain. Forwarding of the message is determined by its opening, and by the individual's perception about the value of the message it may provide to others, besides the…
