The case-study building of this work is the Medieval Inn of Gralheira (“Pousada Medieval da Gralheira”) located in Vila Pouca de Aguiar, Portugal. This building is an example of the structures of that time, located in Trás-os-Montes, Portugal. A large amount of the built heritage suffers from advanced degradation, making the recovery, increasing the complexity of the rehabilitation and restoration intervention and implying a highly specialized interdisciplinary component. Therefore, the purpose of this paper is to carry out a study of the building in order to perform an analysis of its wood floor and assess its structural behaviour and conservation status. This work also presents some examples of intervention methods and rehabilitation techniques used to solve problems in the masonry structure and wood structures.

In this work, a numerical model of a wood pavement of a medieval building is presented, which was developed and calibrated with values obtained in an experimental campaign of wood specimens extracted from the floor structure and the deformation measured in situ. This model aims to analyse and predict the behaviour of the structure in terms of serviceability limit states. Rehabilitation and reinforcing techniques are described, for specific damages, complemented with a critical comparative analysis to define the most appropriate rehabilitation measures for each situation.

In this work, for the numerical model of the medieval building under consideration, the support of the beams in the walls between 50 per cent embedded and simply supported (hinge supports) was used. Since the beams have some restriction imposed by the wall, they have a delivery about 20 cm in the wall. The consideration of the delivery between beam and columns as simply supported (hinge supports) is a reasonable approximation. There is a difference between the values of deformation obtained in the numerical model and in situ due to the support conditions and also due to the consideration of the pavement loads as a distributed load, which does not correspond entirely to reality, since the pavement confers rigidity to the floor, behaving like a diaphragm. The presented intervention techniques are not applicable in all structures because each building has different characteristics, in terms of materials and construction. The pathologies occur due to many sources and each case is unique, and must be carefully studied before taking decisions about the rehabilitation methods to use.

This work presents a numerical model of wood pavement of a medieval building developed according to some experimental values obtained in an experimental campaign using wood specimens extracted from original beams and based on in situ measurements. This study is part of master thesis of Michael Andrade, an original research work.

The antique structures are part of the inheritance that our elders left, being important to preserve their memories. It is important to preserve, rehabilitate and restore the historic buildings protecting the cultural patrimony, attending to the actual comfort and habitability requirements. It is necessary to study the behaviour of the various elements that compose antique structures (masonry and wood) in order to develop assessment measures according to the characteristics of the original materials. The paper aims to discuss these issues.

An experimental campaign to characterize the mechanical behaviour of the wood of the roof of the “sequeiro” of “Quinta Lobeira de Cima”, a building from the twentieth century located in Minho, was carried out. The tested wood specimens are from two different species: chestnut and oak. Compression, tension and static flexion tests according to parallel to the grain direction were performed. Other parameters, such as density, moisture content and longitudinal modulus of elasticity in compression and in tension, were also obtained. The measurement of displacements was made with Digital Image Correlation (DIC).

The results of this study show the similarity between experimental and empirical values for the studied woods species.

This original study aimed at characterizing the mechanical properties using DIC of wood of the roof of the “sequeiro” of “Quinta Lobeira de Cima”, a building from the twentieth century located in Minho (Portugal). This study is part of master thesis of João Martins, an original research work.

This paper aims to investigate if the world top manufacturing corporations' cost structures are moving from tangible to intangible activities and their impact on profitability.

The theoretical approach is interdisciplinary, combining global value chains, international manufacturing networks, cost management literatures. The empirical approach has a sample out of financial statements' data from 220 multinational corporations between 2006 and 2017, grouping them by technological intensity. It is created the “COGS-share” indicator – the ratio between the costs of goods sold and overall costs and expenses – as a proxy for the firms' expenses of tangible and intangible value chain activities. It is tested as an explanatory variable for the companies' profits through dynamic panel data econometric models.

The results show that the cost structure still is very concentrated in tangibles. Though costs of both tangible and intangible activities negatively impact profits, they affect value generation differently: the higher the share of intangible in comparison to tangible activities in overall cost and expenses, the greater the profits in most manufacturing groups, regardless of their technological intensity.

The empirical analysis simplifies the composition of value chains per activity because financial statements data are aggregates, preventing detailed analysis by markets, business units or products. Stocks' levels are assumed to be at the desired level during the time series. The dataset does not allow value curves to be drawn because direct wages' data and more precise information on cost (especially deferred assets and wages) are missing.

The presented approach, particularly the COGS-share indicator, contribute to assess value generation from activities for improving corporate strategies and public policies on operations and cost management of global value chains.

Supporting upgrading decisions that impact value production, allocation and distribution between workers, firms and countries.

Interdisciplinary theoretical and empirical assessment of the manufacturing companies' cost structures and profits based on financial statements data for the better understanding of value generation from tangible and intangible activities.

Based on the theory of trust and cost-benefit perspective, this paper examines the relationship between citizens’ trust and their digital attitudes by considering the mediating effects of performance expectancy and perceived risk, as well as the moderating effect of media use.

The city digital transformation in Shanghai is chosen as the case in this study. 466 questionnaires were collected through a survey, with Structural Equation Modeling to test the hypotheses in AMOS.

Citizens’ trust of government and trust of technology has no significant direct effect on their digital attitudes. However, performance expectancy mediates between the trust of government and digital attitudes, and perceived risk mediates the effect of trust of technology on attitudes. The use of social media significantly moderates the association between trust of technology and citizens’ attitudes.

Exploring why citizens shape supportive attitudes toward digitalization is critical to achieving digital governance goals in developing countries, especially large cities where digital transformation is accelerating. The originality lies in using cost-benefit analysis as a perspective and media use as a moderator to examine the mechanisms of citizens’ trust and digital attitudes.

The purpose of this paper is to describe six recovery-oriented peer support experiences and strategies implemented in different regions of Brazil in the past 12 years, and explore challenges to their development and potential for empowerment and citizenship.

In this paper, a group of stakeholders in mental health services involving people with lived experience of severe mental illness describe their experiences with services of peer support. These were all conducted in Brazil and in partnership with the International Recovery and Citizenship Collective (IRCC) and The Yale Program for Recovery and Community Health. The authors met monthly to exchange experiences, studies and practices, and six experiences were selected, described, analyzed and compared. A discussion of these experiences, their challenges, impact and potential followed.

The explored experiences emphasize that peer support, lived experience leadership and advocacy are feasible in the Brazilian mental health system and can help advance the Brazilian Psychiatric Reform.

This paper is limited to the experience of researchers already engaged in peer support work in six cities in Brazil. Although they represent several different regions in Brazil, there are areas it has not reached. Further research should address and provide a broader view of peer support and recovery strategies spreading in the country.

These experiences demonstrate the feasibility and acceptability of the recovering citizenship approach to reduce stigma, promote empowerment, autonomy, activism and advocacy, and increase a sense of belonging for those in recovery and marginalized by society. The Brazilian psychiatric reform can benefit from including peer supporters as mental health treatment providers.

This paper provides a novel view of the state of the art of peer support initiatives in Brazil and can inspire individuals, government and communities as they see and understand the breadth, depth and meanings of these peer support experiences.

This study aims to estimate the overall SARS-CoV-2 seroprevalence and evaluate the accuracy of an antibody rapid test compared to a reference serological assay during a COVID-19 outbreak in a prison complex housing over 13,000 prisoners in Brasília.

The authors obtained a randomized, stratified representative sample of each prison unit and conducted a repeated serosurvey among prisoners between June and July 2020, using a lateral-flow immunochromatographic assay (LFIA). Samples were also retested using a chemiluminescence enzyme immunoassay (CLIA) to compare SARS-CoV-2 seroprevalence and 21-days incidence, as well as to estimate the overall infection fatality rate (IFR) and determine the diagnostic accuracy of the LFIA test.

This study identified 485 eligible individuals and enrolled 460 participants. Baseline and 21-days follow-up seroprevalence were estimated at 52.0% (95% CI 44.9–59.0) and 56.7% (95% CI 48.2–65.3) with LFIA; and 80.7% (95% CI 74.1–87.3) and 81.1% (95% CI 74.4–87.8) with CLIA, with an overall IFR of 0.02%. There were 78.2% (95% CI 66.7–89.7) symptomatic individuals among the positive cases. Sensitivity and specificity of LFIA were estimated at 43.4% and 83.3% for IgM; 46.5% and 91.5% for IgG; and 59.1% and 77.3% for combined tests.

The authors found high seroprevalence of anti-SARS-CoV-2 antibodies within the prison complex. The occurrence of asymptomatic infection highlights the importance of periodic mass testing in addition to case-finding of symptomatic individuals; however, the field performance of LFIA tests should be validated. This study recommends that vaccination strategies consider the inclusion of prisoners and prison staff in priority groups.

The wider possibility of connectivity offers additional opportunities for customers to experience value propositions. The online world is only one side of the customer experience. The integration of digital technologies, social presence and physical elements increases the complexity of customer journey. This paper aims to map the phygital customer journey by focusing on millennials.

The study adopted a qualitative methodology to investigate 50 millennials from Italy. Millennials had to describe, in two phases, a journey they had recently made. First, they used sticky notes with no restrictions on expressing their feelings and structuring their CJ. Second, customers transferred the sticky notes’ contents, consider the information provided and map the journey with additional details using the Uxpressia software.

This paper frames the Millennials customer journey as a cycle of four moments: connect, explore, buy and use. Each moment enacts the customer experience as a mixture of emotional, behavioural and social responses. Online and offline interactions blur the boundaries between the physical and digital world (i.e. phygital): millennials move back-and-forth or jump from one action to another according to the evolving path of emotions and interactions.

The phygital customer journey provides an alternative understanding of customer journey occurring as a fuzzy process or loop. A phygital map develops as a circular path of moments seen as phenomenological microworlds of events, interactions, relationships and emotions.
