Estudo piloto: eficácia de um programa para aumento da literacia relaciono com a perturbação obsessivo-compulsiva dirigido a profissionais de segurança privada.
Publication . Gomes, Patrícia Cecília Melo de Soares; Ros, Antónia Maria Jiménez
A perturbação obsessivo compulsiva (POC) é uma condição incapacitante dado o sofrimento associado e o impacto na qualidade de vida dos indivíduos, esta pode apresentar elevados níveis de comprometimento social e profissional. Esta condição carrega um estigma associado, principalmente nas vertentes mais hostis, o que diminui a procura de ajuda, aumentando a tendência para esconder a sintomatologia. Segundo vários estudos níveis elevados de Literacia em saúde mental (LSM) podem estar associados a uma procura mais ativa de ajuda profissional, a uma maior abertura psicológica, menor distanciamento social e níveis de estigma mais reduzidos. Propusemo-nos a este estudo para comparar a viabilidade e eficácia, num estudo piloto, com base num programa de intervenção através das redes sociais, destinado ao aumento da literacia associado à POC. Participaram no estudo 61 indivíduos com a profissão de segurança privada, com idades compreendidas entre os 22 e os 66 anos. Foi pedido aos participantes que visualizassem a história do José, repartida em 12 episódios, no caso da condição experimental: Programa literacia POC e no caso da condição de controlo: Programa literacia Enfarte do Miocárdio. Os resultados da comparação entre os programas sugerem-nos que um programa para aumento de LSM direcionado à POC, estruturado de forma sequencial, pode contribuir para a destigmatização e para o aumento da LSM. Dado ao número reduzido da nossa amostra, e tratando-se de um estudo piloto, os resultados deste poderão ser replicados em ensaios clínicos controlados.
Does guests-perceived value for money affect WOM and eWOM? The impact of consumer engagement on SNS on eWOM
Publication . Quiroga Souki, Gustavo; Oliveira, Alessandro Silva de; Barcelos, Marco Túlio Correa; Martins Guerreiro, Maria Manuela; da Costa Mendes, Júlio; Moura, Luiz Rodrigo Cunha
Purpose – Hotels provide high-quality guest experiences to generate perceived value for money (PVM), positively influencing word-of-mouth (WOM) and electronic word-of-mouth (eWOM) communication. This study aims to (1) verify the impacts of the perceived quality by the guests about their experiences in hotels on their PVM; (2) inspect the influence of guests’ perception of hotel prices on PVM; (3) examine the impacts of guest PVM on their hotel experiences on WOM and eWOM and (4) investigate the consequences of the hotel guests’ behavioural engagement on social networking sites (HGBE-SNS) on eWOM. Design/methodology/approach – This quantitative and descriptive study consists of a survey with 371 guests who evaluated their experiences at three hotels in Brazil. PLS-SEM tested the hypothetical model that resorted to the stimulus-organism-response theory (S-O-R), proposed by Mehrabian and Russell (1974). Cluster Analysis compared the PVM, WOM and eWOM of groups of hotel guests with different levels of social media engagement. Findings – Perceived quality by hotel guests positively impacts PVM. Perceived price negatively influences PVM. PVM had a positive and robust impact on WOM. PVM impacts and explains weakly eWOM. In contrast, HGBE-SNS affects and better explains eWOM than PVM. Originality/value – This unprecedented investigation concomitantly exhibits the relationships between perceived quality, price, PVM, WOM, eWOM and HGBE-SNS. Hotels must offer high perceived quality experiences to influence PVM and WOM positively. PVM is unable to stimulate eWOM strongly. HGBE-SNS is pivotal for guests to share their hotel experiences through eWOM. This study suggests marketing strategies for hospitality companies to amplify customer engagement on SNS.
Understanding host preference of Trioza erytreae (Del Guercio) by a multi-omics approach
Publication . Magalhães, Tomás Thormann Abranches de; Marques, Natália Tomás; Duarte, Amílcar Manuel Marreiros; Pereira, José Alberto Cardoso
The citriculture industry is significantly challenged by the devastating bacterial disease Huanglongbing (HLB). There is currently no eective cure for HLB, its management is based on inoculum elimination, and on the control of its vectors, namely the psyllids Trioza erytreae and Diaphorina citri. While Europe is currently free of HLB, T. erytreae is present in Spain and Portugal, two of Europe’s main citrus producers. The present study aimed to analyse the mechanisms underpinning T. erytreae's interaction with its citrus hosts. The plant hosts used in this study were the highly suitable lemon (Citrus ×limon) and the less suitable sweet orange (Citrus×sinensis). Both hosts were infested with T. erytreae adults, and three times more nymphs developed on lemon than on sweet orange plants. A multi-omics analysis on the plant’s enriched vascular sap of both citrus hosts revealed heightened primary and secondary metabolisms activity of sweet orange plants in response to infestation, including jasmonic acid (JA)-related defence mechanisms. A proteomic
analysis of the nymphs revealed that the diet provided by lemon plants induced growth and energy pathways in T. erytreae. Based on these results, a subsequent experiment was conducted to stimulate the defence responses of lemon plants, analysing its eect on T. erytreae infestation and on the plants’ volatile organic compounds (VOC). Lemon plants were sprayed with JA to activate herbivory-related defences. The JA treatment resulted in a substantial reduction in the number of T. erytreae eggs and nymphs. Furthermore, the VOC profile was found to be aected by infestation and JA treatment, with high emission of (Z)-3-hexenol acetate, 2-hexen-1-ol and carveol. This research provides knowledge that can be used to develop novel methods for T. erytreae control, enhancing the array of responses to the HLB challenge and promoting a sustainable citriculture.
Destinationscape: an integrated and holistic conceptualization
Publication . Bender, Ana Carolina; Agapito, Dora Lúcia Miguel; Martins Guerreiro, Maria Manuela
Destinations are growingly acknowledged as dynamic entities requiring strategic resource management to provide value for stakeholders. In this sense, to be recognized as desirable places to visit, to live or to invest in, with a harmonious integration among the stakeholders, it is imperative to frame destinations’ distinctiveness using the experience marketing perspective. Through a combination of an integrative literature review and an academic panel with diverse expertise, this conceptual research aims to conceptualize and depict the environmental features composing destinationscape as a construct, considering the dynamic interplay of multiple ‘scapes’. As a result, the proposed conceptual framework comprises five second-order and 17 first-order dimensions. This research is expected to contribute to the theory around destination experience and experiencescape by offering a comprehensive view, where destinationscape emerges from continuous interactions between the destination’s external environment and its stakeholders. Consequently, this research contributes to destination competitiveness and governance by conceptualizing and providing a framework around destinationscape.
Noticias da homenaxe a Rosalía de Castro no Porto (1954)
Publication . Novoa Fernández, Olivia
Transcorridos 70 anos, a escultura de Rosalía resiste como lugar de memoria nun entorno que hoxe dista de ser o locus amoenus descrito nos discursos do acto inaugural celebrado en 1954 na Praza da Galiza. A perennidade da pedra, en granito rosa, parece simbolizar, alén dunha paisaxe compartida polo noroeste peninsular, a fortaleza dos lazos que unen o Norte de Portugal e Galicia. Un vínculo, moitas veces vencellado ao ámbito cultural, ao lingüístico e ao literario, mais tamén ao político e as súas consecuentes instrumentalizacións. Este texto propón un ollar ao pasado a través das noticias da inauguración do monumento publicadas nos principais xornais galegos e nos portugueses Jornal de Notícias e O Comércio do Porto. Seguindo algúns parámetros da análise de contido, comparouse a importancia e relevancia dada ao acontecemento nun total de 18 noticias. Esta primeira abordaxe complementouse aínda co estudo do discurso en relación co contexto político a fin de investigar a proxección da imaxe da poeta e o adoutrinamento da fraternidade peninsular.
