Abstract
Purpose
The purpose of this study is to review the existing fatigue and vibration-based structural health monitoring techniques and highlight the advantages of combining both approaches.
Design/methodology/approach
Fatigue monitoring requires a fatigue model of the material, the stresses at specific points of the structure, a cycle counting technique and a fatigue damage criterion. Firstly, this paper reviews existing structural health monitoring (SHM) techniques, addresses their principal classifications and presents the main characteristics of each technique, with a particular emphasis on modal-based methodologies. Automated modal analysis, damage detection and localisation techniques are also reviewed. Fatigue monitoring is an SHM technique which evaluate the structural fatigue damage in real time. Stress estimation techniques and damage accumulation models based on the S-N field and the Miner rule are also reviewed in this paper.
Findings
A vast amount of research has been carried out in the field of SHM. The literature about fatigue calculation, fatigue testing, fatigue modelling and remaining fatigue life is also extensive. However, the number of publications related to monitor the fatigue process is scarce. A methodology to perform real-time structural fatigue monitoring, in both time and frequency domains, is presented.
Originality/value
Fatigue monitoring can be combined (applied simultaneously) with other vibration-based SHM techniques, which might significantly increase the reliability of the monitoring techniques.

Abstract
This chapter examines elements of the regulatory framework in effect in the Brazilian Border Region and neighboring countries as they interact with elements of the culture industry. Located in what is referred to as the Southern Arc, the first city we examine, Foz do Iguaçu-PR, lies on the border between Paraguay and Argentina. The second city is Tabatinga-AM, part of the conurbation region made up by a Colombian city and including the Peruvian border, coming to be known as the Northern Arc.
Our research was produced through the triangulation of primary data obtained in two trips into the field, carried out in 2013 and 2014, secondary data (official and semi-official) and academic bibliography.
Although projects relating to border integration, citizenship and economic development do exist, they do not question or challenge a nationalistic and politicized regime of representation portraying border areas primarily as routes for cocaine traffic or home to terrorist cells. The representation regime disseminated by mainstream media thus reduces the rich color and dynamics of the region to impoverished tones of gray recognizable in terms of “the name of the other.”
This chapter provides a relevant contribution to our understanding of communication processes carried out in two different regions of Brazil, both of them located far from the spotlights of mainstream Brazilian media. We employ a theoretical framework that combines geography of communication with perspectives on communication in borderland regions.

Abstract
The Third Sector has been receiving increasing attention from society, including academics, due to its importance in the face of the lack of government responses to many of the social problems that affect contemporary societies. Theoretically, the State is supposed to highlight the importance of the services provided by Social Solidarity Institutions, given their proximity to the beneficiaries, the efficiency in the distribution of resources and their innovative attitude towards social problems and needs. As a logical consequence, society is witnessing an increase in the participation of the private sector in social issues and a greater professionalisation of the Third Sector in the search for sustainability. Within the Third Sector, Social Solidarity Institutions play a very important role, acting as social actors. Within the environment of Social Solidarity Institutions, the Misericórdias also play a very important role. ‘Misericórdia’ is a non-profit institution that takes a form of charity, very popular in some countries, such as Italy and especially in Portugal. However, there are few studies on the governance conditions of this type of institution. In addition, it is possible to discuss whether there is any study that focuses specifically on this type of analysis. This study fills the empirical gap in the existing literature, providing an insight into the ways of adopting governance practices and principles within these institutions, which over five centuries of existence have continuously worked towards a more just, inclusive and supportive society.

Abstract
Purpose
Tourism in Coimbra today is influenced by the fact that the Univer(s)city was distinguished as a World Heritage Site in 2013. The number of visits has grown very significantly in recent years, but the diversification of the tourist offer is still weak and unable to take advantage of existing resources. This paper aims to present genealogy tourism as an alternative urban cultural tourism in Coimbra.
Design/methodology/approach
Methodology involved mapping the Jewish culture elements in the city of Coimbra, and a route was outlined and proposed.
Findings
Genealogy tourism resources are identified in the historic centre of the city. These alternative spaces need urban rehabilitation and (re)functionalisation, which allowed the authors to rethink tourism in Coimbra. They are the motivation to visit for all urban cultural tourists, especially Israelis/Jews, and provide contact with places where the experiences of ancestors combine with the history and memory of places, with recent discoveries and the elements of Jewish culture in the city.
Originality/value
It is concluded that the quantity, diversity, authenticity and singularity of the heritage resources that bear witness to the Jewish presence in Coimbra are sufficient assets to create a route, to enrich the tourist experience in the city and to include the destination in the Sephardic routes.

Abstract
Purpose
Industry 4.0 not only impacts the manufacturing industry but also supply chain practices. Drawing on the resource-based view (RBV), the purpose of this paper is to examine how Industry 4.0 affects supply chain integration (SCI) and supply chain performance (SCP).
Design/methodology/approach
The data were collected from 212 respondents in manufacturing companies. The partial least square structural equation modelling (PLS-SEM) was used to test the hypotheses of this study.
Findings
The findings reveal that Industry 4.0 has a positive impact on SCI and SCP, and SCI has a positive impact on SCP. In addition, a partial mediating role of SCI has been found between Industry 4.0 and SCP.
Practical implications
This study reveals the role of Industry 4.0 on supply chain practices and draws attention to SCI in the linkage between Industry 4.0 and SCP. The findings emphasise the need for Industry 4.0 and SCI to enhance SCP.
Originality/value
There is limited research on the impacts of Industry 4.0 on SCI and SCP. This research finds empirical evidence for these impacts and enhances knowledge of Industry 4.0 by using a sample from an emerging country.

Abstract
Purpose
Kidney transplantation (KT) is the treatment of choice for end-stage chronic kidney disease (CKD) and is well known to improve the clinical outcome of patients. However, the impact of KT on comorbid psychological symptoms, particularly depression and anxiety, is less clear, and recipients of living-donor (LD) organs may have a different psychological outcome from recipients of dead-donor (DD) organs.
Design/methodology/approach
In total, 152 patients were included and analyzed using a cross-sectional design. Of these patients, 25 were pre-KT, 13 were post-KT with a LD transplant and 114 were post-KT with a DD transplant. The patients were tested for a variety of psychometric outcomes using the Hospital Anxiety and Depression Scale, the 12-Item Short Form Health Survey (assessing physical and mental health-related quality of life), the Resilience Scale, the Coping Self-Questionnaire and the Social Support Questionnaire.
Findings
The mean age of the patients was 51.25 years and 40 per cent of the patients were female. As expected, the post-KT patients had significantly better scores on the physical component of the Short Form Health Survey than the pre-KT patients, and there were no significant differences between the two post-KT groups. There were no significant differences among the groups in any of the other psychometric outcome parameters tested, including anxiety, depression and the mental component of health-related quality of life.
Research limitations/implications
KT and the origin of the donor organ do not appear to have a significant impact on the psychological well-being of transplant patients with CKD. Although the diagnosis and early treatment of psychological symptoms, such as depression and anxiety, remain important for these patients, decisions regarding KT, including the mode of transplantation, should not be fundamentally influenced by concerns about psychological impairments at the population level.
Originality/value
CKD is a serious condition involving profound impairment of the physical and psychological well-being of patients. KT is considered the treatment of choice for most of these patients. KT has notable advantages over dialysis with regard to the long-term physical functioning of the renal and cardiovascular system and increases the life expectancy of patients. However, the data on the improvement of psychological impairments after KT are less conclusive.
