- Amyloid-negative, neurodegeneration-negative amnestic mild cognitive impairmentPublication . Cardoso, Sandra; Guerreiro, Manuela; Montalvo, Alexandre; Silva, Dina; Alves, Luísa; Mendonça, Alexandre deBackground:The concept of amnestic mild cognitive impairment (aMCI) was developed to identify patients at an initial stage of Alzheimer's disease (AD). However, some patients with aMCI do not present biomarkers of amyloid pathology or neuronal injury.Objective:To know the natural history of amyloid-negative and neurodegeneration-negative patients with aMCI, namely to ascertain: 1) whether these patients remain cognitively stable or they present a slow decline in neuropsychological tests; 2) whether the memory complaints subside with the apparently benign clinical course of the disorder or if they persist along the time.Methods:Patients who fulfilled criteria for aMCI with no biomarkers of amyloid pathology or neuronal injury were selected from a large cohort of non-demented patients with cognitive complaints, and were followed with clinical and neuropsychological assessments.Results:Twenty-one amyloid-negative and neurodegeneration-negative aMCI patients were followed for 7.1 +/- 3.7 years. At the baseline they had more pronounced deficits in verbal learning (California Verbal Learning Test) and were also impaired in Word Recall and Logical Memory. However, they did not decline in any cognitive test during follow-up. The patients maintained a high level of subjective memory complaints from baseline (9.7 +/- 4.1) to the follow-up visit (9.2 +/- 4.1, a non-significant difference), in spite of a statistically significant decrease in the depressive symptoms, with Geriatric Depression Scale (15 items) score 4.9 +/- 2.8 at baseline and 3.2 +/- 1.8 at the follow-up visit. Conclusions: Amyloid-negative, neurodegeneration-negative aMCI is a chronic clinical condition characterized by the long-term persistence of cognitive deficits and distressing memory complaints. Adequate strategies to treat this condition are needed.
- Can Subjective Memory Complaints Identify A beta Positive and A beta Negative Amnestic Mild Cognitive Impairment Patients?Publication . Mendes, Tiago; Cardoso, Sandra; Guerreiro, Manuela; Maroco, Joao; Silva, Dina; Alves, Luisa; Schmand, Ben; Gerardo, Bianca; Lima, Marisa; Santana, Isabel; de Mendonca, AlexandreBackground: The use of biomarkers, in particular amyloid-beta (A(beta) changes, has allowed the possibility to identify patients with subjective memory complaints (SMCs) and amnestic mild cognitive impairment (aMCI) who suffer from Alzheimer's disease (AD). Since it is unfeasible that all patients with aMCI could presently undergo biomarkers assessment, it would be important that SMCs might contribute to identify the aMCI patients who have AD amyloid pathology. Objectives: To know whether aMCI patients with amyloid biomarkers (A beta(+)) present greater SMCs as compared to those without amyloid biomarkers (A beta(-)). Methods: Participants were selected from a cohort of nondemented patients with cognitive complaints and a comprehensive neuropsychological evaluation, on the basis of 1) diagnosis of aMCI
- Cidade, património e marketing: gestão estratégica da imagem da cidade de SilvesPublication . Guerreiro, Manuela; Fortuna, CarlosA presente dissertação discute até que ponto os atributos culturais e históricos, materializados em elementos arquitectónicos e urbanísticos, constituem a principal fonte de diferenciação na actual guerra inter-cidades e até que ponto são decisivos no processo de construção da imagem da cidade. A investigação empírica analisou a cidade de Silves, cuja presença é transversal em toda a dissertação. Pretendeu-se identificar o atributo potencialmente mais eficaz para posicionar estrategicamente a cidade junto dos públicos e assim interferir na formação da sua imagem. Os estudos efectuados, quer junto dos visitantes quer de um grupo de indivíduos com acção mais ou menos directa na gestão estratégica do posicionamento da cidade de Silves, levam-nos a concluir que os elementos tangíveis de natureza islâmica são os principais atributos da sua imagem. Deverá, por isso, ocorrer um esforço integrado no sentido de posicionar Silves como uma cidade patrimonial islâmica no Algarve. Definido o vector estratégico principal, todas as acções de divulgação, preservação e valorização da cidade e dos seus recursos histórico-culturais contribuirão para a respectiva consolidação.
- Delay discounting in mild cognitive impairmentPublication . Coelho, Sara; Guerreiro, Manuela; Chester, Catarina; Silva, Dina; Maroco, Joao; Paglieri, Fabio; de Mendonca, AlexandreIntroduction: Patients with mild cognitive impairment (MCI) may make suboptimal decisions particularly in complex situations, and this could be due to temporal discounting, the tendency to prefer immediate rewards over delayed but larger rewards. The present study proposes to evaluate intertemporal preferences in MCI patients as compared to healthy controls. Method: Fifty-five patients with MCI and 57 healthy controls underwent neuropsychological evaluation and a delay discounting questionnaire, which evaluates three parameters: hyperbolic discounting (k), the percentage of choices for delayed and later rewards (%LL), and response consistency (Acc). Results: No significant differences were found in the delay discounting questionnaire between MCI patients and controls for the three reward sizes considered, small, medium, and large, using both k and %LL parameters. There were also no differences in the response consistency, Acc, between the two groups. Conclusions: Patients with MCI perform similarly to healthy controls in a delay discounting task. Memory deficits do not notably affect intertemporal preferences.
- Design and marketing: Intersections and challengesPublication . Henseler, Jörg; Guerreiro, ManuelaThis editorial article reports on interdisciplinary research being conducted at the interface between the scientific disciplines of marketing and design. It reviews the 11 academic papers from the special issue situated at this intersection, thereby showing the richness of research happening in this liminal area. At the same time, the paper observes how the disciplines' different scopes as well as their different modi operandi inhibit the collaboration between marketing and design research. Whereas marketing largely follows the paradigm of empirical realism asking how the current world works, design largely follows the pragmatist paradigm asking how a future world can be shaped. Finally, this paper contains a number of suggestions on how to foster cooperation between the two disciplines.
- Designing accessible tourism experiences: slow, sensory and smart frameworkPublication . AGAPITO, DORA; Guerreiro, ManuelaSlow tourism is an emergent research area focused on slowing the pace of life during vacations. A comprehensive multi-sensory approach can contribute to designing enhanced slow tourism experiences deemed accessible, both in situ and remotely. There is a research gap in considering multi-sensory stimuli in the design of accessible tourism experiences using technology. As such, this research intends to propose a theoretical framework focused on the development of slow tourism through sensory cues and smart technologies. In so doing, a critical approach to literature was carried out by intersecting three areas of literature following the rationale of the Stimuli-Organism-Response model: slow tourism, multi-sensory tourism experiences design, and smart destinations. The significance of this framework is threefold: it strengthens local identities and aids sustainable tourism by involving the community; it promotes experiences deemed authentic considering multiple stakeholders’ perspectives; and it addresses the visitor experience before, during and after the visit to the destination in an accessible manner using smart technologies. A framework with six steps is offered based on participatory methods.
- Examining the relationship between hoteliers’ review site use intensity and hotel characteristics - Moroccan HotelsPublication . Ait-Bakrim, Abderrahman; Attouch, Hicham; Guerreiro, Manuela; Perez-Aranda, Javier R.Due to rapid development and consumer adoption of technology, the hospitality industry has dramatically increased online-based user-generated reviews for a variety of services, such as those found in eWOM communities (e.g., TripAdvisor). Few studies have tested-among eWOM communities-the correlation between hoteliers' review site use intensity and hotel characteristics. The purpose of this paper is to examine the predictors of TripAdvisor use intensity, as perceived by Moroccan hoteliers. After the literature review on user-generated content, a quantitative study based on a structured questionnaire survey was developed, and correlation analyses were conducted to empirically validate the relationship between hotel characteristics and the use of TripAdvisor among a population of 48 hotel managers. The results showed that all variables studied commitment, competence, hotel size (number of beds), hotel category, and type of ownership were positively related to the intensity of use of review sites. This study deepens hotel practitioners' understanding of the importance of user-generated content and offers suggestions on how to improve eWOM advocacy. Moreover, this paper contributes to the recent and still scanty research line on eWOM from the hoteliers' perspective. The novelty lies in the positive relationships between hotel features (commitment, competence, hotel size, hotel category, and type of ownership) and user-generated review sites (TripAdvisor). It extends current literature and provides practitioners with some guidance on user-generated content and hotel characteristics.
- From tourist experience to satisfaction and loyalty: exploring the role of a sense of well-beingPublication . Bagheri, Fatemeh; Guerreiro, Manuela; Pinto, Patrícia; Ghaderi, ZahedDrawing on the authentic happiness theory, the aims of this article are three-fold: first, to propose a refined measurement scale for tourists’ sense of well-being; second, to investigate the impact of four categories of tourist experience on tourists’ sense of well-being; and third, to explore the effect of the sense of well-being on tourists’ satisfaction and loyalty. Data were collected from tourists spending their holidays in the Algarve, Portugal. To address the lack of an integrated measurement scale for assessing tourists’ sense of well-being, an exploratory factor analysis was initially conducted. Subsequently, the data were analyzed using structural equation modeling in WarpPLS 8.0. The findings reveal a three-dimensional scale for tourists’ sense of well-being, consisting of meaningfulness, active pleasure, and release. The results also show a significant positive impact of the four realms of tourists’ experiences on the sense of well-being. Finally, positive relationships between well-being, tourist satisfaction and loyalty are confirmed. The theoretical and practical implications, limitations, and potential directions for future research are discussed.
- Hedonic experiences at heritage attractions: the visitor’s perspectivePublication . Bender, Ana Carolina; Guerreiro, Manuela; Sequeira, Bernardete; Mendes, JúlioPurpose The purpose of this study is to explore the hedonic experience and its formation at heritage attractions. Design/methodology/approach A qualitative and exploratory approach was applied, using data from 21 semi-structured interviews and three in-situ focus groups. Findings Findings highlight that senses, imagery and emotions are stimulated by the physical landscape and by triggers of memorable experiences. Research limitations/implications To further explore this topic, a broader range of heritage attractions and perspectives from the diverse stakeholders involved in the management and consumption of these sites is needed. Originality/value Given the scarcity of research dedicated to the hedonic experience at heritage sites, this study provides a contribution by exploring the visitor's perspective and points out relevant insights. As the hedonic feelings of pleasure, comfort and related affective responses impact the quality of memorable experiences, relevant implications for theory and practice are discussed.
- How do residents experience their own festivals? A qualitative approach to meanings and experiencesPublication . Brás, Nídia; Mendes, Júlio; Guerreiro, Manuela; Sequeira, BernardeteRural communities have recently been using events as tools for local development, especially if they are part of their community development policies (Richards & Palmer 2010; Ziakas & Costa 2010; Ziakas 2016). Economic benefits, feelings of belonging to the community, Urban regeneration, quality of life, and cultural and social benefits are usually recognised as the main impacts of events (Fredline, Jago, & Deery 2003; Chalip 2006; Richards & Palmer 2010; Schulenkorf & Edwards 2012; Ziakas 2016). Ziakas (2016) suggests that more research into the impacts of cultural or festival events is needed (Ziakas 2016). Moreover, de Geus, Richards and Toepoel (2016, p. 276) argue that literature ‘on event experiences is very scarce and fragmented’. There is little understanding of what kind of meanings and experiences residents attach to a festival that occurs in the place where they live. Therefore, this study aims to examine the meanings and experiences residents ascribe to a festival in a local community in a small inland region in Portugal – Mértola. Mértola is a small town with 7,274 inhabitants (Instituto Nacional de Estatística [Statistics Portugal] 2011), located in the interior of Portugal. The abundant archaeological remains from the Muslim occupation in the 11th and 12th centuries have given rise to several little museums within the town, which are one of the main tourist attractions and a source of pride for the inhabitants. Known as ‘Museum Town’, Mértola has been the stage of the Mértola Islamic Festival since 2001. The event takes place every two years and ‘seeks to evoke and preserve the heritage of the Muslim period in the south of the Iberian Peninsula’ (Câmara Municipal de Mértola 2015, p. 8). The methodology included semi-structured interviews with residents from different areas of the town and had three main objectives: (i) to understand the experiences of residents in the Islamic Festival, (ii) to understand the meanings that residents attach to the Islamic Festival and (iii) to characterise the most relevant memories of their participation in this festival. Findings of this study are likely to make significant contributions to theory and practice by furthering our understanding of how residents feel and experience the events that take place in their own cities. Also, the study highlights the often-undervalued role of residents as meaning makers and as consumers of the event.
