Abstract
Purpose
This paper aims to explain how FC Porto became an important agent on the contribution for the development of tourism in the city of Porto.
Design/methodology/approach
The paper is based on information drawn from official sources and relevant data from Futebol Clube do Porto.
Findings
Through the football matches and since the migration of the club’s headquarters to the eastern district of the city, during the mid-1950s, FC Porto proved to be responsible for bringing attention and public to the city of Porto and then to an area where progress was missing.
Originality/value
The FC Porto Museum has been able to capture strong interest and satisfaction from visitors less connected to the phenomenon of sports, attracted by the theme of a museum of a sports club that speaks the language of the city, the region and the country.

Abstract
This chapter examines the professional identities of Brazilian journalists. It does so through an analysis of the growing professional autonomy of journalism from 1950 to 1990 through the life stories of 10 intellectual-journalists, individuals whose journalistic activities have crossed over into other intellectual fields.
This study applies a symbolic interactionist framework to understand how these actors managed their reputations and careers within the intellectual world. The narratives were taken from qualitative semi-structured interviews, and supported by additional research such as interviews, biographies, and articles which have been published about their lives.
The life stories were compared to the extensive structural changes affecting the world of journalism and the world of intellectuals in Brazil. This comparison revealed gaps between these two spheres of practice, within which the ambivalent form of journalists’ identities have been constructed.
This chapter offers two contributions to the study of Brazilian journalists. From a theoretical and methodological viewpoint, it advances beyond other studies that focus more on the prevailing representations of journalists’ professional identities and their role in society. From an empirical standpoint, it describes the complex negotiations between the worlds of journalism, culture and politics. This chapter also reexamines the current dominant explanation for the changes in Brazilian journalism. It shows that building careers and new levels of interpersonal cooperation for intellectuals and journalists has been a slow process. Ultimately, this development has left some behind, especially those actors stretched between multiple professional identities such as those who self-identify as intellectual-journalists.

Abstract
Purpose
The purpose of this paper is to address the case of toxic metal contamination of Sepetiba Bay caused by the Ingá Company. The paper reviews the history of the contamination and discusses the current presence of metals in the bay sediments, demonstrating that the toxic metals are clearly enriched. Sepetiba Bay is prone to significant dredging activities that make metals available in the food chain, affecting human populations, mainly fishermen communities.
Design/methodology/approach
The study presents the case of the Ingá Company based on international literature and data provided by previous studies.
Findings
Through the analysis and compilation of diverse data from the literature, this study demonstrates that the Ingá Company is a major source of Cd, Pb and Zn due to its calamine processing activities used to obtain high purity Zn.
Originality/value
This study highlights important research to complete the historical scenario of heavy metal contamination of the Sepetiba Bay by Ingá Company. The results indicate that the contaminants from the Ingá Company can indeed be traced in the sediments of Sepetiba Bay. These data have the utmost value for the environmental management of this coastal system, because such high concentrations of toxic metals in marine sediments have serious implications for the environmental quality of the bay and may negatively affect biota and human health. Therefore, this study suggests that it is now necessary to monitor this region for contamination continuously.

Abstract
Purpose
The West African Republic of Guinea-Bissau has been unstable since gaining its independence in 1974. The 2014 presidential and parliamentary elections are being closely analyzed to study how the United Nations and the Guinean people have reacted to the outcomes of these elections. The paper aims to discuss these issues.
Design/methodology/approach
Sociological methodologies and a comparative approach have been used in this paper to understand why the elections in 2014 were so important in this country.
Findings
The author finds that stability is possible in Guinea-Bissau after years of political uncertainties.
Originality/value
Particular focus has been paid to studying the responses of specific aspects of society, including the youth population, the political elite, the main political party, the African Party for the Independence of Guinea and Cape Verde, the opposition parties and the army and whether these different groups will be able to cooperate after electing a sustainable and relatively wide-ranging government.

The study aims to analyze the influence of managerial support, autonomy and reward perception on the innovative behavior of university professors.
Abstract
Purpose
The study aims to analyze the influence of managerial support, autonomy and reward perception on the innovative behavior of university professors.
Design/methodology/approach
Quantitative methodology based on partial least squares structural equation modeling. The sample obtained totaled 208 responses from professors at three public universities in the State of Sao Paulo, Brazil.
Findings
The results indicate that managerial support is a fundamental factor for developing an organizational environment that is more conducive to innovative behavior and corporate entrepreneurship. However, in educational institutions with a more focused entrepreneurial ecosystem, it was discovered that reward perception is not a fundamental factor for the innovative behavior of university professors.
Practical implications
From a practical perspective, academic institutions interested in stimulating corporate entrepreneurship should create opportunities for collaboration among professors to solve problems, encourage professors to expose their work beyond the university environment and improve the main indicators of management support and autonomy presented in this research.
Social implications
The study presents indicators and implications, which are of particular interest for university managers and public policy writers.
Originality/value
The study is demonstrably original. Through its unique analysis of the innovative behavior of university professors and the connections between variables in the university environment and its use of a robust modeling method in an emerging-economy context, the study furthers existing research by helping to understand why some firms are better than others at corporate entrepreneurship.

Abstract
Like many other countries, a reform of school meals policies has been implemented in Portugal, wherein nutritional and health criteria are considered in the design of the public plate. Given that a large literature on school meals focus on cities seen as sites for promising transformation regarding health, resilience and sustainability, it is pertinent to examine how these policies are being received in rural areas. Similar to other vulnerable regions in southern Europe, rural areas in Portugal have been affected by depopulation, the re-localisation of public services (e.g. schools, health centres and courts of justice) to larger conurbations, a drastic reduction of farming areas and its reconversion from sites of production to sites of consumption that thrive on tourism. While research on children’s attitudes, experiences and practices in rural areas had picked up the attention of social scientists, research on children’s relations and engagements with school meals in these areas does not abound. This chapter addresses three issues: first, how the catering staff and health professionals experience children’s engagements with school meals after the policy reform; second, how the discourses of the school staff and parents around the rural and gastro-idylls contrast with the reported food practices and experiences of everyday life, and third, how the multiple engagements of children with animals, plants and other nature conflict with or are juxtaposed to the images of the rural idyll. Drawing from focus groups material with children aged between 7 and 9 years old living in the rural hinterland of an inland medium-size city in Portugal, focus groups with parents and interviews with stakeholders (e.g. school and kitchen staff, local authorities, nutritionists and catering firms) the chapter aims at contributing to a broader understanding of children lived experiences with food consumption in rural contexts.

Abstract
Purpose
Universities have become both increasingly entrepreneurial and international over the past few decades. We still, however, know little about the relationship between the two trends. This paper investigates the effect of international exposure of university faculty members on university entrepreneurial culture.
Design/methodology/approach
Using a specially constructed dataset of the entrepreneurial activities of 507 computer science faculty members—among whom 138 are returnees—from 21 research-intensive universities in China during 2007–2017, the study empirically investigates the relationship between foreign experience and academic entrepreneurial activity back home. We control for characteristics of the faculty member and the location of the university.
Findings
Academic tenure overseas is found to positively affect academic entrepreneurship. The length of stay abroad also affects the relationship: returnee academics with foreign Ph.D. degrees are more likely to start new businesses than returnee academics with shorter postdoc experience overseas. The economic gap between the host (foreign) and home country (China) does not have a statistically significant effect on returnee academic entrepreneurial activity.
Originality/value
To the best of our knowledge, this study is the first to empirically investigate returnee academic entrepreneurship. It provides indications on how foreign educational background affects academics entrepreneurial activities.

Abstract
Purpose
When investors experience extreme uncertainty, they seek “safe havens” to reduce their risk, to limit their losses and to protect the value of their portfolios. The purpose of this paper is to examine the safe-haven properties of Bitcoin compared to the stock market.
Design/methodology/approach
Based on intraday data, this study compares the price efficiencies of Bitcoin and Morgan Stanley Capital Index (MSCI) using Multifractal Detrended Fluctuation Analysis for the second half of 2020. This study then evaluates Bitcoin’s safe-haven property using Detrended Partial-Cross-Correlation Analysis (DPCCA).
Findings
This study finds that the price efficiency of Bitcoin is lower than that of MSCI. Further, Bitcoin was not a safe haven at any time for the MSCI index. The net cross-correlations between Bitcoin and MSCI are weak and they vary at different time scales.
Research limitations/implications
The behavior of market prices varies over time. Therefore, it is important to replicate this study for other time periods.
Social implications
The paper sheds light on the price behavior of Bitcoin during a period of instability. The results suggest that the construction of portfolios should differ based on the time horizons of the investors.
Originality/value
The authors compare Bitcoin against a global equity index instead of a specific country index or commodity. They also demonstrate the applicability of DPCCA in finance research.

Abstract
Purpose
The investigation of the fractal nature of financial data has been growing in the literature. The purpose is to investigate the multifractal behavior of frontier markets using multifractal detrended fluctuation analysis (MFDFA).
Design/methodology/approach
This study used daily closing prices of nine frontier stock markets up to 31-Aug-2020. A preliminary analysis reveals that these markets exhibit fat tails and clustering patterns. For a more robust analysis, a combination of Seasonal and Trend Decomposition using Loess (STL) and MFDFA has been employed. The former method is used to decompose daily stock returns, where later detected the long rang dependence in the series.
Findings
The results confirm varying degree of multifractality in frontier stock markets, implying that they exhibit long-range dependence. Based on these multifractality levels, Serbian and Romanian stock markets are the ones exhibiting least long-range dependence, while Slovenian and Mauritius stock markets indicating highest dependence in their series. Furthermore, the markets of Kenya, Morocco, Romania and Serbia exhibit mean reversion (anti-persistent) behavior while the remaining frontier markets show persistent behaviors.
Practical implications
The information given by the detection of the fractal measure of data can support for investment and policymaking decisions.
Originality/value
Frontier markets are of great potential from the perspective of international diversification. However, most of the research focused on other emerging and developed markets, especially in the context of multifractal analysis. This study combines the STL method and a physics-based robust technique, MFDFA to detect the multifractal behavior of frontier stock markets.

Abstract
Purpose
The purpose of this paper is to validate and apply enrichment diagrams (EDs) to determine metal and as enrichment and contamination in the sediments of Sepetiba Bay.
Design/methodology/approach
Through inducted coupled plasma – optical emission spectrophotometry, total element (As, Cd, Cu, Ni, Pb and Zn) concentrations were assessed for the construction of EDs and comparison with enrichment factors (EFs) in 65 samples collected in Sepetiba Bay.
Findings
Based on the EDs, it was observed that the sediments around the urban area of Sepetiba and ItaguaíHarbor were contaminated with Cd, Cu, Ni, Pb and Zn. These contaminants were expected due to the urban and industrial discharges into the bay and the activities at ItaguaíHarbor.
Originality/value
The ED was successful regarding its ability to evaluate inorganic contamination in Sepetiba Bay. In addition, this method was able to define a proper background sample for calculating EFs.
