Intergenerational caregiving: the role of attachment and mental representation of caregiving in filial anxiety of middle-aged children
Get PDFAdult children may experience filial anxiety when anticipatingthe need to care for their aging parents. To investigate theextent to which attachment and mental representation of car-egiving predict filial anxiety, a cross-sectional study was con-ducted among 304 middle-age adults with at least one livingparent aged 65 or more. Results suggest that the variance in filialanxiety is mainly accounted for by the mental representation ofcaregiving and then by attachment. These findings suggest thatmental representation of caregiving and attachment are impor-tant dimensions to consider when adult children feel unpre-pared and worried with the need to care for their aging parents.E51F-89A1-B769 | Carla FariaN/

Travelling and discovering new destinations after the COVID-19´S lockdown: the role of routines and habits
No full textThe paper identifies the level of importance determined by the consumer as far as traveling and discovering new destinations are concerned, after the lockdown caused by the health crisis triggered by the coronavirus pandemic. A sample of 445 respondents is used, and an ordered logit econometric model is applied to estimate the importance level of travelling and enjoying a new destination considering the respondents’ sociodemographic characteristics and the level of importance attributed
to meeting new people, visiting their families, going back to work, meeting their friends, eating out in a restaurant and attending musical and other cultural events. The main conclusions are related to consumers who believe it is very important to travel for specific reasons, such as meeting new people and friends or visiting their families, eating out in a restaurant or attending musical or other cultural events. Family and friends play an important role, considering that to visit them is seen as a priority. This
study provides a relevant assessment regarding the priorities defined by the consumers in the scope of the discovery of new destinations, thus providing inputs to the different stakeholders involved in the definition of strategies for the promotion of tourism destinations.B913-0565-0908 | Elvira Vieirainfo:eu-repo/semantics/publishedVersio
Trabalho experimental no 1ºCEB: concepções e práticas de professores
No full textA comunicação que se apresenta respeita a uma fase preliminar de um estudo mais
alargado que visa identificar concepções e práticas dos professores do 1CEB do distrito de
Viana do Castelo relativamente ao trabalho experimental (TE), tendo em vista a avaliação
do impacto do Programa de Formação em Ciências Experimentais para Professores do
1CEB (PFPEEC ) na evolução/mudança dessas concepções e práticas. Os dados obtidos
através da aplicação de um inquérito a um grupo restrito de professores não permitem
inferir a existência de uma relação causa efeito entre estas duas variáveis, já que o número
de respondentes não envolvidos na formação foi escasso e não se observaram diferenças
significativas entre os dois grupos. A frequência de realização de TE nas escolas
envolvidas fica aquém do que se seria desejável, sendo ainda questionável se o que
realizam são actividades em que há controlo e manipulação de variáveis ou apenas
actividades com manipulação de materiais. Isto, porque a maior parte dos respondentes
aponta o manual escolar como principal fonte na preparação dessas aulas, e é sabido que
esses recursos condicionam o tipo de actividades práticas realizadas em contexto de sala de
aula e geralmente não incluem actividades tipo TE. Os resultados obtidos sugerem a
necessidade de reformular o questionário antes de o utilizar no estudo principal, recorrendo
a instrumentos diversificados de recolha de dados de modo a aferir da realidade das
práticas e, consequentemente, concluir sobre o impacto da frequência do PFPEEC.C917-B3FD-1A62 | Maria Luísa Vieira das Nevesinfo:eu-repo/semantics/publishedVersio
Visual solutions as a resource to promote mathematical learning
No full textSeeing is an important component in mathematical understanding, that can be developed, learned
and taught. It is important to teach students how to see what is necessary, proposing challenging
and adequate tasks. The use of visual solutions can be an alternative to the use of concepts that the
student may not have learnt, and an easier way to solve a given situation. Therefore, the
mathematics class should include practices and resources that lead students to think visually from
experiences that imply this type of thinking. We intend to discuss some of these ideas and present
examples of tasks, with multiple solutions, developed in the scope of a teacher training course.0D1E-4824-1244 | Ana Cristina Coelho Barbosainfo:eu-repo/semantics/publishedVersio
Feedback and written mathematics communication: a pen pal exchange
Get PDFThis paper describes a study that aims to understand and characterize the written communication of future
primary education teachers in a context of a pen pal exchange with 3rd grade students (8 years old), in
particular the nature of the feedback. We followed a qualitative methodology, where data were collected
through observation, written productions (letters) and an interview with the participants. Each future
teacher was paired with two students, and four letters were written by the participants over the course of
ten weeks. The first letter had the intent of presenting themselves and knowing the recipient. In the
following letters the dialogue was continued and the pre-service teachers posed challenging mathematical
tasks for the students to solve and for them to give feedback. We focused our analysis in the quality of
written communication/feedback, the perceptions of future teachers about the potential of this experience
and difficulties experienced. The dynamics of the correspondence exchange allowed the records to be
prepared with great commitment. When selecting the tasks, they realized the importance of knowing the
curricular guidelines, as well as the contents that the students were addressing. The tasks posed varied
from exercises/problems centred on contents addressed by the students. The feedback sent was quite
diverse. In some cases, it was not informative, and was even quite superficial; in other situations, the
comments provided indicated hints for future action, seeking to promote learning. The exchange of
correspondence by letter enabled the sharing of ideas, access to mathematical knowledge, the formulation
of tasks, promoting the development of written communication.0D1E-4824-1244 | Ana Cristina Coelho BarbosaN/
Outdoor solutions for the seasonal concentration of tourism demand in northern portugal: an integrated approach based on the gini index
Get PDFMeasures that address the seasonality, one of the identified overtourism direct causes, allow making a
critical reflection on the application of control policies and monitoring regional measures crucial on a sector with such importance at the regional development analysis. The measures should stimulate or
reduce tourism demand during low or peak seasons, respectively, generating a better distribution of
tourism flows and eliminating potential overtourism situations. Therefore, this chapter focuses on the
development of a Gini Index to analyse the distribution of the seasonality in northern Portugal and
through it control current public measures in practice and suggest the implementation of different and
more effective policy measures. For instance, the ones that make a clear bet on outdoor tourism activities. It will be used in the Gini Index, by the tourists’ market of origin measured by the overnight stays in hotel establishments. The results showed the high seasonal concentration of tourist flows.691D-6753-BE59 | Manuel José Serra da Fonsecainfo:eu-repo/semantics/publishedVersio

Microstructure and electrical properties of aluminium-substituted La(Sr)Ga(Mg)O3-δ-based solid electrolytes
Get PDFA study of the influence of the substitution of Al for Ga in the ceramic processing and electrical properties of La0.95Sr0.05Ga0.90–xAlxMg0.10O3–d (0 B x B 0.3) solid electrolytes is presented. The materials retained orthorhombic symmetry over the entire substitution range, whereas a deviation from Vegard’s law for x[0.20 suggested a maximum Al solubility of x = 0.20. Scanning electron microscopy analysis of ceramic samples revealed that grain growth was inhibited for x C 0.2. This microstructural change was related to an apparent deterioration of mechanical properties, as suggested by room-temperature
Vickers hardness measurements. Impedance spectroscopy revealed a significant degradation of the grain-boundary electrical properties for x C 0.20, whereas the bulk conductivity was enhanced for 0.10 B x B 0.15. Oxygenpermeability measurements confirmed that the studied materials remain essentially pure ionic conductors. An ionic conductivity maximum of 0.047 S/cm at 700 C was obtained for x = 0.10. The effect of aluminium in the grainbulk ionic conductivity is discussed in terms of defect cluster
models and assuming fast oxygen diffusion along domain walls.371C-9F16-EBDE | Eduarda GomesN/
Effect of Pr3+/Pr4+ ratio on the oxygen ion transport and thermomechanical properties of the pyrochlore and fluorite phases in the ZrO2-Pr2O3 system
Get PDFThis paper examines the effect of the Pr3+/Pr4+ ratio on the mechanism of ionic and electronic transport in the (Pr2−xZrx)Zr2O7+x/2 (x = 0.15), Pr2Zr2O7, and Pr2(Zr2−xPrx)O7−x/2 (x = 0.1) pyrochlore phases and Pr3ZrOx with the fluorite structure and on the behavior of their thermal expansion coefficient (TEC). The solid solutions were prepared through coprecipitation followed by firing of the green compacts in air at a high temperature of 1550 °C for 4 h. The Pr3+/Pr4+ ratio was shown to decrease in going from the (Pr2−xZrx)Zr2O7+x/2 (x = 0.15), Pr2Zr2O7, and Pr2(Zr2−xPrx)O7−x/2 (x = 0.1) pyrochlores to the Pr3ZrOx fluorite, leading to changes in the conductivity type from mixed (ionic–electronic) to electronic and in the color of the materials from beige to black and to an anomalous deviation of the TEC from linearity in fluorite Pr3ZrOx, i.e. at the highest Pr4+ content. According to impedance spectroscopy results, (Pr2−xZrx)Zr2O7+x/2 with x = 0.15 has purely oxide-ion conductivity (3 × 10−3 S/cm at 1000 °C) in a wide range of oxygen partial pressures: from 10−10 to 102 Pa. With increasing Pr content, p-type electronic conductivity becomes significant, reaching a maximum in fluorite Pr3ZrOx: ∼0.5 S/cm at 1000 °C. According to XPS data, all pyrochlore samples (Pr2−xZrx)Zr2O7+x/2 (x = 0.15), Pr2Zr2O7 and Pr2(Zr2−xPrx)O7−x/2 (x = 0.1) contain only Pr3+ at room temperature, whereas Pr3ZrOx contains both Pr3+ and Pr4+. The considerable deviation of the TEC of Pr3ZrOx from linearity above 500 °C is due to partial reduction of Pr4+. The reduction process Pr4+ + e′ → Pr3+ followed by oxygen release in the range 500–1100 °C has been identified in Pr3ZrOx by thermal analysis and mass spectrometry in a He atmosphere.371C-9F16-EBDE | Eduarda GomesN/
