Marriage and care of a spouse with dementia: a cross-cultural study Brazil-Portugal

This study aimed to analyze the meaning of marriage and care of the spouse from the perspective of Brazilian and Portuguese caregivers of elderly people with Alzheimer Disease (AD). Twelve women participated in the study, being the sample obtained by convenience using the snowball technique. We used a questionnaire and a semi-structured interview, data were analyzed by the Bardin content analysis technique. The results pointed out that although the cultural differences between Brazil and Portugal, some meanings related to marriage and care of the spouse in the context of AD were similar for Brazilian and Portuguese wives. Despite marital changes related to dementia, most wives felt well performing their role of caregiver, perhaps because among other variables, this is a task traditionally and culturally expected to be performed by women of both countries.info:eu-repo/semantics/publishedVersio

Monogenic polynomials of four variables with binomial expansion

In the recent past one of the main concern of research in the field of Hypercomplex Function Theory in Clifford Algebras was the development of a variety of new tools for a deeper understanding about its true elementary roots in the Function Theory of one Complex Variable. Therefore the study of the space of monogenic (Clifford holomorphic) functions by its stratification via homogeneous monogenic polynomials is a useful tool. In this paper we consider the structure of those polynomials of four real variables with binomial expansion. This allows a complete characterization of sequences of 4D generalized monogenic Appell polynomials by three different types of polynomials. A particularly important case is that of monogenic polynomials which are simply isomorphic to the integer powers of one complex variable and therefore also called pseudo-complex powers.Fundação para a Ciência e a Tecnologia (FCT

Does customer-based reputation add to social and mass media reputation in judging social responsibility of banks?

Purpose: Reputation is a critical asset for finance and banking organizations where the mere suspicion of a problem suffices to trigger media turmoil with high risk of market share losses. Investing in media to build reputation has been therefore a priority for banks. However, another source of reputation may stem from direct front-office contact and it is yet unknown to which extent it plays a role when confronted with the widespread social and mass media reach. This study aims at testing the extent of the importance of customer-based reputation, as against media-based reputation, in explaining customer outcomes.info:eu-repo/semantics/publishedVersio

A voltammetric tool for the evaluation of propolis antioxidant activity

Propolis (bee glue) is a sticky dark-colored material that honeybees collected from parts of plants, buds and exudates, and used as construction and defense material in the hive. This resinous substance is a rich source of phenolic compounds, and its chemical composition is strongly influenced by its phytogeographic origin. This research outlines the evaluation of the redox profile and the quantification of the total antioxidant capacity in Portuguese propolis from different origins and potential floral sources Populus x canadensis Moench and Cistus ladanifer L through cyclic voltammetry and differential pulse voltammetry. Although several oxidation processes were showed by propolis samples, which were dependent of the resin origin, common oxidation potentials within the majority of samples of a region were detected, suggesting an analogous chemical composition in respect of electroactive species. Based on the quantification of the total electroactive antioxidant power, it was found that propolis with higher antioxidant activity was from coast center, followed by north ~ Azores Archipelago > central interior > Madeira Island > south.Soraia I.
