What is the potential of the luxury resale market in Portugal?
The purchase of pre-owned luxury goods is becoming a worldwide trend. With growing concerns over sustainability and the search for different and unique pieces, new ways of consuming luxury have emerged, especially among the younger generations, giving a boost to the second hand luxury market. However, in the Portuguese market this trend is almost non-existent and have just started to give its first step early this year. In an attempt to study the potential of growth for this market in Portugal, 14 in-store observations to the already established luxury resale business models were conducted, as well as 31 in-depth interviews to luxury consumers and 3 interviews to luxury resale retailers. Results showed that there is an interest both to purchase and sell second hand luxury items, suggesting the high potential of the market in Portugal. Moreover, it was found that the best business model to be applied to the Portuguese market is a closed-doors system, with a personalized and exclusive service similar to a luxury store with an omnichannel interaction with a physical store and an online website
Desenvolvimento de aluminas coradas para aplicação em joalharia
Mestrado em Tecnologia Cerùmica na Escola Superior de Tecnologia e Gestão do Instituto Politécnico de Viana do CasteloTendo em conta a crescente procura pela inovação dos produtos estéticos/acessórios
por parte dos jovens designers, surgiu interesse em aliar as caracterĂsticas da cerĂąmica,
nomeadamente brilho e cor Ă joalharia feita em todo o mundo.
Este trabalho pretende produzir uma palete de cores, que funcionarĂĄ como catĂĄlogo de
cores disponĂveis para os designers incluĂrem nos seus projectos. Para tal, realizou-se um
estudo de cor numa matriz de alumina, corada com vĂĄrios pigmentos. Testaram-se
diferentes teores de vĂĄrios pigmentos e verificou-se o desenvolvimento da cor apĂłs
cozedura e apĂłs polimento.
A produção de amostras de alumina com as diferentes quantidades de pigmento,
processou-se por prensagem a seco numa prensa hidrĂĄulica manual. Realizou-se o
tratamento tĂ©rmico da amostra a 1200ÂșC, com posterior polimento. Esta temperatura de
sinterização foi seleccionada, após a realização de diversos testes e se ter verificado que
muitos dos pigmentes sĂŁo instĂĄveis para temperaturas superiores. Desta forma conseguiuse
alargar o leque de cores produzidas.
Como complemento ao trabalho, também se realizaram ensaios sobre uma alumina
proveniente de resĂduos industriais. E efectuou-se o estudo de uma lama de anodização
proveniente da LacoViana que após calcinação origina alumina. Os resultados destes
ensaios demonstraram pior desempenho do que o verificado com a alumina pura, o que
combinado com o facto de a joalharia ser um produto de alto valor acrescentado e se
produzir em pequenas quantidades, reduz o interesse deste tipo de reciclagem industrial.Given the increasing demand of young designers for the innovation of aesthetic
products and/or accessories, the combination of ceramic characteristics, including
brightness and colour, with the jewellery made in the world, becomes a new challenge for
new products.
This work intends to do a colour study of the effect of various pigments contents into
an alumina matrix and find out the progression of the colour after sintering and also after a
polish treatment.
For this, alumina samples with different amounts of pigment were prepared by
uniaxial press. The sintering process it was done at 1200°C. This low sintering temperature
it was selected after several tests which demonstrates pigment instability for higher
temperatures. Thus it was possible to extend the range of colors produced.
Taking into account environmental issues, it was also analysed the possibility of use
an anodizing slurry rich in alumina, from Lacoviana company. This slurry, after a
calcination process it is almost constituted by alumina. One of the pigments used with the
high grade alumina, was also tested with this industrial waste, to allow a comparison
between this two different aluminas. The results of these trials showed a worse
performance than that observed with pure alumina, which combined with the fact that
jewellery is a product of high added value and is produced in small amounts, reduces the
attractiveness of this type of industrial recycling
InfluĂȘncia da aptidĂŁo fĂsica e morfolĂłgica no sucesso acadĂ©mico: um estudo longitudinal retrospectivo
Diversos estudos mostram que as escolas que oferecem intensos programas de Atividade FĂsica promovem o sucesso acadĂ©mico das crianças e jovens, com aumento da concentração, melhoria da interpretação oral e escrita e de cĂĄlculos matemĂĄticos, bem como com um aumento dos nĂveis das funçÔes mental e de aprendizagem. O objetivo deste estudo foi analisar como a AptidĂŁo FĂsica (ApF) e a AptidĂŁo MorfolĂłgica (ApM) se relacionam com o Sucesso AcadĂ©mico (SA). Trata-se de um estudo quantitativo, com anĂĄlise estatĂstica a partir dos resultados do âEstudo Morfofuncional da Criança Vianenseâ (EMCV) e dos resultados escolares de uma cohort de 312 alunos (172 rapazes e 140 raparigas) obtidos no 9Âș ano de escolaridade. Recorrendo a uma anĂĄlise correlacional retrospectiva, avaliĂĄmos a nossa amostra em termos de ApF, ApM e de SA no ano de 2006 e de uma forma retrospectiva em outros trĂȘs momentos distintos, anos 2000, 1999 e 1998.
Os resultados mostraram que o nĂvel de ApF se relacionou positivamente com o SA no 9Âș ano, sendo esta a variĂĄvel que tem maior influĂȘncia no desempenho acadĂ©mico. A ApM, embora nĂŁo estatisticamente significativa, foi tendencialmente positiva no SA no sexo feminino e negativa no sexo masculino. A variĂĄvel sexo Ă© um factor que influencia o SA de forma muito significativa, mostrando que ser do sexo feminino parece ser condição preferencial para a obtenção de melhores resultados acadĂ©micos.Fundação para a CiĂȘncia e a Tecnologia (FCT) - unidade de investigação 31

No ùmbito dos estudos de adaptação e validação do WHOQOL-OLD, foram
implementados oito grupos focais, num total de 33 participantes, em amostra de
conveniĂȘncia: um com profissionais em formação (N=4), um com cuidadores
(N=4) e seis grupos com adultos idosos (N=25; quatro com idosos da comunidade e dois com idosos institucionalizados). Os resultados corroboram a natureza
multidimensional do constructo QdV. Foram evocados espontaneamente os seis
domĂnios do WHOQOL-100 e todas as suas facetas (exceptuando Actividade sexual), bem como as seis facetas do WHOQOL-OLD. Com maior frequĂȘncia, oadultos idosos destacam Qualidade de vida e saĂșde geral e dimensĂ”es de RelaçÔes
sociais, Ambiente, PsicolĂłgico, Aspectos espirituais e Autonomia; os cuidadores
referem dimensĂ”es de Autonomia, SaĂșde, Ambiente e RelaçÔes sociais; e os profissionais destacam SaĂșde, NĂvel de independĂȘncia, Ambiente e RelaçÔes sociais.
Por todos os grupos foi apontada a dimensĂŁo âFamĂlia/Vida familiarâ, que poderĂĄ constituir-se como uma nova faceta do mĂłdulo WHOQOL-OLD portuguĂȘs
Compassion and extracurricular activities of Portuguese Health Sciences students in Portugal
Background
Compassion, one of the items of empathy, is crucial in health care professions. So, the evaluation of the levels of compassion of Medicine, Dentistry and Pharmaceutical Sciences Master Degreesâ (M.D.) students of the public Colleges in Portugal according to the type of Master Degree and the participation in extracurricular activities (E.A.) was a task to be performed.
Methods
Cross-sectional study in 2020, applying an on-line questionnaire including the âCompassionâ items of the Jefferson Medical Empathy Scale â Studentsâ version and questions about the participation in E.A.
Results
A sample of 901 students was studied. Its distribution by participation in E.A. did not differ significantly between M.D. (p =â0,854), most of the students participating in E.A. Using quartile distribution of compassion, the distribution of compassion levels was different among the three I.M. (p <â0.001), between Colleges (p <â0.001), and between curricular years (p <â0.001), with not different between genders (p =â0.036). For 56.4%, 74,6% and 69,5% of the respondents there was âmedium-lowâ and âlowâ compassion for I.M. in Medicine, Pharmaceutical Sciences and Dentistry. These levels were also more prevalent among students in the 1st and 5th years. Levels of compassion were not different with the participation (p =â0,865), type (p =â0,177) and frequency of E.A. (p =â0,109).
Conclusions
For their importance in future health care professionals, compassion and their differences found among the M.Ds. of this area deserve future studies. Levels of compassion showed differences between the M.D. studied and academic years of frequency. There was no relationship between the participation, type, and frequency of E.A. and the studentsâ levels of compassion.
The distribution of the level of compassion did not vary significantly with participation in E.A. (p =â0.865), with the type of E.A. (p =â0.177), with the frequency of E.A. (p =â0.109) or with the answer to the question âThe practice of E.A. can make a person more compassionate?â (p =â0.503).info:eu-repo/semantics/publishedVersio
Health literacy and cardiovascular complications in people with type 2 Diabetes
Background
Cardiovascular complications are the main causes of death for type 2 diabetes. Their relationship to socioeconomic factors, such as health literacy, is not well known.
Objectives
To study the relationship between health literacy and cardiovascular complications (acute myocardial infarction, cerebrovascular accident, transient ischemic attack and ischemic heart disease) in type 2 diabetes patients and to understand the relationship of type 2 diabetes mellitus associated cardiovascular disease with empowerment and therapy adherence.
Material and methods
A cross-sectional study with a convenience sample of people with type 2 diabetes in central Portugal. Socio--demographic and clinical characteristics (blood pressure, LDL cholesterol, hemoglobin A1c and history of cardiovascular diseases) were collected, and validated scales were applied to assess health literacy, adherence to therapy, empowerment and quality of life. Bivariate inferential analysis between literacy, other variables and cardiovascular diseases, with subsequent Logistic Regression, was performed.
Results
A sample of n = 202, mean age 68.11 ± 10.19 years, n = 116 (57.4%) males was studied. Higher health literacy was significantly associated with a lower prevalence of cardiovascular diseases (p = 0.015). This relationship was independent of the remaining variables (OR = 0.947; 95% CI: 0.913â0.982; p = 0.003). Significant relationships were demonstrated between cardiovascular disease and quality of life (p = 0.001), adherence to total therapy (p = 0.045), general diet (p = 0.002), physical activity (p = 0.027), age (p = 0.004) and LDL cholesterol (p = 0.036).
Conclusions
The independent relationship between health literacy and cardiovascular disease in people with type 2 diabetes, when confirmed, will indicate that health literacy promotion acts as an important health policy measure to be adopted.info:eu-repo/semantics/publishedVersio
