Local governments increasingly justify the hosting of mega-events because of their legacy value, assuming that all local residents benefit from those events. Yet, little attention has been paid to the distributive question of who benefits from the transport legacy left by those events. This paper reflects on the delimitation of transport legacies and its social impacts in terms of how such developments can reshape urban accessibility to opportunities. It analyses the transformation in the transport system of Rio de Janeiro (Brazil) in preparation for the 2014 World Cup and the 2016 Olympic Games. That transformation involved substantial expansion in public transport infrastructure, followed by cuts in service levels and a reorganization of many bus lines to streamline the transport system. The paper examines whether those recent changes have increased the number of people from different income levels who could access Olympic sports venues and healthcare facilities by public transport within 15, 30, 60 and 90 min. The analysis uses a before-and-after comparison of Rio's transport network (2014–2017) and a quasi-counterfactual scenario to separate the effects of newly added infrastructure from the reorganization and cuts of transport services. The results show that the infrastructure expansion alone would have increased the number of people who could access the Olympic sports venues, but it would have only marginally improved people's access to healthcare facilities. Nonetheless, the findings indicate that the streamlined bus system have offset the benefits of infrastructure investments in a way that particularly penalizes the poor. The analysis of both the implemented changes to the public transport network and the counterfactual scenario show that the accessibility benefits from the recent cycle of investments and disinvestments in Rio generally accrued to middle- and higher-income groups, reinforcing existing patterns of urban inequality.

This work investigates the relationship between the political and institutional environment and the development of entrepreneurship in Mozambique. Taking a literature review approach and using collected empirical data from interviewing 10 individuals playing different roles with impact on county's entrepreneurial landscape, results support existing theory and suggest that this African country still has a long way to go in what relates governmental action to entrepreneurial development. ; info:eu-repo/semantics/publishedVersion

Purpose: The goal of this research is to examine the link between employees' beliefs that organizational decision-making processes are guided by self-serving behaviors and their own turnover intentions, as well as how this link may be buffered by four distinct resources, two that speak to the nature of peer exchanges (knowledge sharing and relationship informality) and two that capture critical aspects of the organizational environment (change climate and forgiveness climate). Design/methodology/approach: Quantitative survey data were collected among 208 employees who work in the oil and gas sector in Mozambique. Findings: The results indicate that employees' beliefs about dysfunctional political games stimulate their plans to quit. Yet this translation is less likely to occur to the extent that their peer relationships are marked by frequent and informal exchanges and that organizational leaders embrace change and forgiveness. Practical implications: For organizations, these findings offer pertinent insights into different circumstances in which decision-related frustrations are less likely to escalate into quitting plans. In particular, such escalation can be avoided to the extent that employees feel supported by the frequency and informal nature of their communication with colleagues, as well as the extent to which organizational leaders encourage change and practice forgiveness. Originality/value: This study adds to extant research by explicating four unexplored buffers that diminish the risk that frustrations with politicized decision-making translate into enhanced turnover intentions. ; info:eu-repo/semantics/acceptedVersion

With a basis in conservation of resources theory, this article considers the connection between employees' resilience and disruptive creative behaviour-conceptualized herein as the extent to which they generate radically new ideas for organizational improvement-as well as how this connection might be invigorated by resource-draining work conditions that stem from excessive workloads and unfavourable decision-making processes. Data collected through a survey administered to employees in an organization that operates in the distribution sector reveal that employees' resilience levels spur their disruptive creative behaviour, and this process is more prominent among employees who believe they have insufficient time to complete their work tasks (i.e., suffer from high work overload) and operate in organizational climates marked by high rigidity or dysfunctional politics. The findings accordingly inform organizational practitioners that the allocation of employees' personal resource bases to disruptive creative behaviours might be particularly useful among employees who face substantial adversity in their organizational functioning. ; info:eu-repo/semantics/acceptedVersion

This article discusses the transposition of the principles normally applied in business management to Higher Education Institutions (HEI). In particular, it discusses the influence exerted by managerialism in the structuring and operation of Higher Education Institutions. In the empirical study conducted in Mozambique, the positions of different actors on different dimensions and categories of the problem are analyzed, supported by a methodology of qualitative analysis from a sample of 9 IES. The main conclusions reveal that in Mozambican higher education there remains a certain resistance from the higher education communities, particularly from its professionals, to the intrusion of managerialism, highlighting a position favorable to collegiality and democracy. Despite the existing criticism, some (minority) actors recognize the influence of managerialist contributions to the objectives of higher education and the design and materialization of HEI management, proposing a hybrid model that associates the two dimensions. The study also reveals a deficit in the participation of the higher education community in management and decision-making processes, making it difficult to apply the collegial model. ; info:eu-repo/semantics/publishedVersion

Over the past decades, transport researchers and policymakers have devoted increasing attention to questions about justice and equity. Nonetheless, there is still little engagement with theories in political philosophy to frame what justice means in the context of transport policies. This paper reviews key theories of justice (utilitarianism, libertarianism, intuitionism, Rawls' egalitarianism, and Capability Approaches), and critically evaluates the insights they generate when applied to transport. Based on a dialogue between Rawlsian and Capability Approaches, we propose that distributive justice concerns over transport disadvantage and social exclusion should focus primarily on accessibility as a human capability. This means that, in policy evaluation, a detailed analysis of distributional effects of transport policies should consider minimum standards of accessibility to key destinations and the extent of which these policies respect individuals' rights and prioritize disadvantaged groups, reduce inequalities of opportunities and mitigate transport externalities. A full account of justice in transportation requires a more complete understanding of accessibility than traditional approaches have been able to deliver to date.

Purpose: The digital paradigm people live in today, which drastically increased the consumption of data, is a threat to their privacy. To create a high level of privacy protection for its citizens, the European Union proposed the General Data Protection Regulation (GDPR), which introduces obligations for organizations regarding the storing, processing, collecting and disclosing of data. This paper aims to identify the critical success factors of GDPR implementation. Design/methodology/approach: A systematic literature review was conducted by following a strict review protocol, where 32 documents were found relevant to perform the review and to answer to the proposed research questions. Findings: The critical success factors of GDPR implementation were identified, including barriers and enablers. Furthermore, benefits of complying with GDPR were identified. Research limitations/implications: As GDPR is a relatively recent subject, there are still few scientific papers about it. Therefore, the authors were unable to neither identify nor present a robust conclusion regarding specific topics, such as practical outcomes. Originality/value: On the basis of the literature, the identified critical success factors may be useful for organizations as these can be better prepared to achieve compliance by prioritizing the enablers and avoiding the barriers. ; info:eu-repo/semantics/acceptedVersion

Purpose: Data can nowadays be seen as the main asset of organizations and data leaks have a considerable impact on the organization's image, revenues and possible consequences to the affected clients. One of the most critical industries is the bank. Information security frameworks (ISF) have been created to assist organizations and other frameworks evolved to update these domain practices. Recently, the European Union decided to create the general data protection regulation (GDPR), applicable to all organizations dealing with personal data of citizens residing in the European Union. Although considered a general regulation, GDPR implementation needs to align with some industries' laws and policies. Especially in the Bank industry. How these ISF can assist the implementation of GDPR is not clear. Design/methodology/approach: The design science research process was followed and semi-structured interviews performed. Findings: A list of practices to assist the bank industry in GDPR implementation is provided. How each practice map with assessed ISF and GDPR requirements is also presented. Research limitations/implications: As GDPR is a relatively recent subject, it is hard to find experts in the area. It is more difficult if the authors intend to find experienced people in the GDPR and bank industry. That is one of the main reasons this study does not include more interviews. Originality/value: This research provides a novel artefact to the body of knowledge. The proposed artefact lists which ISF practices banks should implement to comply with GDPR. By doing it the artefact provides a centralized view about which ISF frameworks (or part of them) could be implemented to help banks comply with GDPR. ; info:eu-repo/semantics/acceptedVersion

Abstract. Monitoring of volcanic activity is important for learning about the properties of each volcano and for providing early warning systems to the population. Monitoring equipment can be expensive, and thus the degree of monitoring varies from volcano to volcano and from country to country, with many volcanoes not being monitored at all. This paper describes the development of a wireless sensor network (WSN) capable of collecting geophysical measurements on remote active volcanoes. Our main goals were to create a flexible, easy-to-deploy and easy-to-maintain, adaptable, low-cost WSN for temporary or permanent monitoring of seismic tremor. The WSN enables the easy installation of a sensor array in an area of tens of thousands of m2, allowing the location of the magma movements causing the seismic tremor to be calculated. This WSN can be used by recording data locally for later analysis or by continuously transmitting it in real time to a remote laboratory for real-time analyses. We present a set of tests that validate different aspects of our WSN, including a deployment on a suspended bridge for measuring its vibration.
Portable analytical systems are increasingly required for clinical analysis or environmental monitoring, among others, being materials with tailored physicochemical properties among the main needs for successful functional implementation. This article describes the processing of fluorinated poly(vinylidene-co-trifluorethylene), P(VDF-TrFE), membranes with tailored morphological and physicochemical properties to be used as microfluidic substrates for portable analytical systems, commonly called point-of-care systems in the medical field. The morphology of the developed membranes includes spherulitic, porous, randomly oriented, and oriented fibers. Furthermore, the processed hydrophobic P(VDF-TrFE) membranes were post-treated by oxygen plasma to make them superhydrophilic. The influence of morphology and plasma treatment on the physicochemical properties and capillary flow rates was evaluated. Microfluidic systems were then designed and printed by wax printing for the colorimetric quantification of glucose. The systems comprise eight reaction chambers, each glucose concentration (25, 50, 75, and 100 mg dL–1) being measured in two reaction chambers separately and at the same time. The results demonstrate the suitability of the developed microfluidic substrates based on their tailorable morphology, improved capillary flow rate, wax print quality, homogeneous generation of colorimetric reaction, and excellent mechanical properties. Finally, the possibility of being reused, along with their electroactive properties, can lead to a new generation of microfluidic substrates based on fluorinated membranes. ; Portuguese Foundation for Science and Technology (FCT) under strategic funding UID/FIS/04650/2020, UIDB/04436/2020, UIDP/04436/2020 and projects PTDC/EMD-EMD/28159/2017 (POCI-01-0145-FEDER-028159).
