Street art in Aveiro: city walls as dialogic spaces of collective memories and identity

In urban centers around the world, street art has become an unavoidable element of the landscape. Located in west-central Portugal, Aveiro is no exception to this trend, and the art form has been used to enhance the cultural vibrancy of a place where tourism is one of the most important economic pillars. Seeking to look beyond the value of street art as a tourism product, by combining observations and photos from field research with bibliographic and documental data, as well as residents’ responses on social media, this paper adopts an autoethnographic approach to offer an exploratory, (self-)reflexive perspective on how street art has evolved into a phenomenon that has contributed to locals’ cultural identity (re)construction. Drawing on Jan Assmann’s cultural memory theory, it is argued that street art can be understood as a form of communicative memory, an ephemeral vehicle into our history, knowledge, traditions and practices, one that, by retelling the story of who we are, stimulates awareness of selfhood and a feeling of belonging to a place and a community.publishe

Interiorização e Novas Centralidades Urbanas: Uma Visão Prospectiva para o Brasil

Este artigo apresenta e analisa o processo de interiorização e criação de novas centralidades urbanas. Baseado nas Regiões de Influência das Cidades definidas pelo IBGE em 1993 e 2007, de projeções populacionais e de impactos regionais dos investimentos do Programa de Aceleração do Crescimento (PAC) para 2020, usando técnicas de análise multivariada e Equilíbrio Geral Computável (EGC), o que podemos perceber nos últimos anos é o surgimento de uma rede urbana embrionariamente policêntrica, com maior ou menor qualificação, no interior da região Centro-Sul, no Brasil Central, no Nordeste não litorâneo e em parcela do “arco da ocupação” da região Centro-NorteInteriorização, Centralidade Urbana, Brasil

Microstructural Characterization of Al/CNTs Nanocomposites after Cold Rolling

The deformation behaviour of aluminium reinforced by carbon nanotubes (Al/CNTs) nanocomposites during cold rolling was investigated in this work. Deformation processes after production by conventional powder metallurgy routes may be an efficient approach to improve the microstructure and mechanical properties by decreasing the porosity. Metal matrix nanocomposites have enormous potential to produce advanced components, mainly in the mobility industry, with powder metallurgy being one of the most reported production processes. For this reason, it is increasingly important to study the deformation behaviour of nanocomposites. In this context, nanocomposites were produced via powder metallurgy. Advanced characterization techniques carried out the microstructural characterization of the as-received powders and produced nanocomposites. The microstructural characterization of the as-received powders and produced nanocomposites was carried out through optical microscopy (OM), and scanning and transmission electron microscopy (SEM and TEM), complemented by electron backscattered diffraction (EBSD). The powder metallurgy route followed by cold rolling is reliable for Al/CNTs nanocomposites. The microstructural characterization shows that the nanocomposites exhibit a different crystallographic orientation than the Al matrix. CNTs in the matrix influence grain rotation during sintering and deformation. Mechanical characterization revealed that during deformation, there is an initial decrease in the hardness and tensile strength for the Al/CNTs and Al matrix. The initial decrease was attributed to the Bauschinger effect being more significant for the nanocomposites. The difference in the mechanical properties of the nanocomposites and Al matrix was attributed to distinct texture evolution during cold rolling

Delirium Pós-Operatório em Cirurgia Vascular

OBJECTIVES: The objectives of this study were to determine the incidence of Postoperative Delirium and to identify specific perioperative risk factors in patients undergoing Vascular Surgery. Other goals were to study its impact in hospital length of stay and to create an algorithm to deal with patients under suspicion of Postoperative Delirium. MATERIAL AND METHODS: A total of 56 consecutive vascular surgery patients were prospectively evaluated. Exclusion criteria were age less than 18, dementia, abnormal level of consciousness, psychiatric disorder and visual or hearing impairment. Mini Mental State Examination were applied during pre-anesthetic visit. In patients with clinical indicators of delirium the Confusion Assessment Method was applied. Patients were assessed during 5 days after surgery. RESULTS: The overall incidence of delirium was 12,5%, developped mostly by the second to fifth postoperative day. Patients with delirium presented moderate to severe pain. Patients who received combined general and regional anesthesia didn't develop delirium. The median hospital length of stay was 21 in patients with delirium and 7 days in patients without (p 0.001). CONCLUSIONS: The overall incidence of postoperative delirium was lower than previously reported. The incidence of delirium was higher in ICU patients and pain was associated with postoperative delirium suggesting the opportunity to control postoperative factores. The development of delirium in the second and fifth day indicated the need for early and more prolonged preventive and diagnosing measures. Clinical and costly considerations of prolonged hospital stay shown in this cohort warrant strong debate strategies to be applied.info:eu-repo/semantics/publishedVersio

Youth involvement in alcohol and drug prevention: A systematic review

To review and analyse how youth involvement was conceptualised and applied in published alcohol and drug preventive interventions. A systematic review of the scientific literature on alcohol and drug prevention where young people (18–29 years old) participated at any stage of the intervention was conducted. We searched relevant bibliographic databases and online repositories for peer-reviewed studies published between 2001 and 2021. Twenty-seven articles reporting on studies in different countries and settings and using various intervention strategies were eligible for inclusion. The analysis of the stages of youth involvement and the dimension of power sharing in decision-making showed that only a minority of studies could be considered genuinely youth-led whereas many involved young people merely as implementers of highly controlled research-led interventions. However, the few studies that promoted sustained youth involvement struggled with translating results into rigorously evaluated interventions, thus demonstrating a tension between adoption of effective interventions and support to genuinely participatory processes. Knowledge gaps and implications for practice and research are discussed from a participatory research perspective.info:eu-repo/semantics/publishedVersio

Perceived ethical reputation: Scale development and validation

Ethical reputation reflects organizations’ commitment to ethics (Jaramillo, Grisaffe, Chonko, & Roberts, 2009; Mulki & Jaramillo, 2011), based on perceived occurrences of ethical problems (Armstrong, 1996) and ways organizations treat their employees and customers (Dawkins & Lewis, 2003). Having a favorable reputation may lead to favorable consequences, such as attracting higher-quality applicants, enhanced job attitudes, and increased employee ethical conduct (Fombrun & Shanley, 1990; Turban & Cable, 2003). However, a comprehensive measure to assess employees’ perceptions of the ethical reputation of their organizations is still missing. Therefore, the present study attempts to develop and validate such a measure. A pool of items reflecting the different dimensions of the construct was drawn from the existing literature on business ethics and organizational reputation. The relevance and clarity of those items was assessed by experts to assure content validity. In order to assess the psychometric characteristics of the scale, data are being collected via convenience sampling. The target sample comprises employees from organizations of different business sectors. Subsequently, analyses to determine construct validity and reliability will be performed. Results will be presented at the conference. The present research is expected to provide a new and useful tool for measuring ethical reputation of organizations, to be used in future research on the issue.info:eu-repo/semantics/publishedVersio
