All case studies were developed in Porto, Portugal, between 2013 and 2020, focusing on the citys invisibilities and everyday experiences, searching for alternative narratives to the mainstream media when portraying its people and places. This article aims to reflect on how authorial documentary work, followed by self-criticism and self-reflection, can be incorporated into participatory media frameworks in productive ways. The challenges faced by the three cases are intrinsically related and have influenced each other throughout this period, addressing issues related to the representational crisis; the legitimation of subjectivity and the exploration of different styles within documentary; as well as the relationships between the filmmaker, the camera, the subject/character portrayed and the audience. These themes are explored through a series of first-person field reports and the study of authors and directors in the field of documentary filmmaking. (c) 2024 The Author(s).

Healthcare is a prime example of a service inherently transformative, with patient experience (PX) playing a critical role. However, the literature lacks a comprehensive understanding of PX and its effects on patients' well-being. To bridge this research gap, semi-structured interviews were conducted, involving healthcare managers, providers and patients, revealing nine key dimensions of PX, critical to patients' well-being. This study advances CX literature and TSR by proposing a conceptual framework on PX and its transformative effects, while offering managerial insights for improving well-being and experiences in healthcare. 2025-01-01T00:00:00Z https://hdl.handle.net/10216/173463 Title: Don't let it go to waste: preventing and profiling household food waste Abstract: Food waste (FW) is an ongoing global issue with detrimental repercussions, which is receiving increased academic and managerial attention. However, the literature lacks theory-driven insights and consumer-tailored approaches, presenting contradicting findings. This study aims to understand household FW, examining drivers and barriers to its prevention. Drawing on data from 950 consumers, an extended model of the Theory of Planned Behaviour was applied, adding two new variables: moral norms and habits. Moreover, household segments were identified based on FW levels, sociodemographic and psychographic attributes. Findings show that habits, perceived control, moral and subjective norms play a significant role in reducing household FW, revealing an intention-behaviour gap. This research offers marketers crucial insights into household FW, particularly highlighting the need to target the 'Oblivious Wasters' and 'Full House' segments with behavioural change interventions. By understanding specific segments and addressing their distinct characteristics, marketers can develop more precise and impactful FW prevention strategies, maximizing efforts and resources. 2026-01-01T00:00:00Z https://hdl.handle.net/10216/172792 Title: POTARCH INDUSTRIES AND ENVIRONMENTAL IMPACT FROM THE MIDDLE AGES TO THE EARLY MODERN PERIOD 2025-01-01T00:00:00Z https://hdl.handle.net/10216/172789 Title: Female CEOs, SMEs performance and internationalization: empirical evidence from European peripheral and Nordic countries Abstract: Purpose This study aims to determine the performance of women-led small and medium-sized enterprises (SMEs) relative to male-led SMEs in the context of European peripheral and Nordic countries, concerning sales, employment, productivity, investment, export intensity and innovation. Design/methodology/approach: We conduct an empirical analysis using an instrumental variable (IV) and a quantile IV quantile regression approach to analyze data drawn from the World Bank Enterprise Surveys (WBES) database. Findings: The authors find that the performance of women-led SMEs relative to male-led SMEs is better in innovation and equal in other dimensions; in Nordic Countries, it is equal; and in peripheral countries, it is higher in innovation and investment but worse in sales and productivity growth, mainly in median-performing firms; in non-exporting SMEs, it is worse in sales and employment growth and better in investment and innovation; and in exporting SMEs with the highest employment growth rates, it is worse in this dimension. Research limitations/implications: Policymakers interested in reducing gender gaps should support CEOs by investing in policies designed to actively support female entrepreneurs, especially if they are in domestic firms (e.g. mentorship, networking and partnership programs; export coaching). Originality/value: The paper innovates by focusing on different measures of firm performance and considering the importance of socio-cultural factors as performance determinants. The value of this novel approach is confirmed by the results, which clearly show that SME's performance cannot be extrapolated from single indicators alone and is strongly affected by contextual factors. 2026-01-01T00:00:00Z https://hdl.handle.net/10216/165502 Title: FDI determinants in developing countries: a firm-level analysis Abstract: FForeign direct investment (FDI) has been an important driver of economic growth in developing countries. Between 2005 and 2017, FDI grew significantly in developing countries as the corresponding global growth rate of FDI inflows is around 32 percentage points higher than the world growth rate. The purpose of this paper is to analyze FDI determinants at the firm level in developing countries. Using a sample of 96,826 firms from 125 countries between 2005 and 2017, we adopt a fractional probit regression with endogenous covariates, a more suitable estimation method for addressing the FDI variable. The micro-level results show that exports, investment, and human capital have a statistically positive impact on FDI inflows, while credit barriers and taxes have a negative effect. Also, market size and resources foster FDI, whereas inflation and environmental emissions lower foreign investment levels. This study demonstrates that governments wishing to attract FDI should adopt a variety of policies, including the promotion of international trade and measures that boost investment and human capital in firms and ease the access to credit. 2025-08-01T00:00:00Z https://hdl.handle.net/10216/170574 Title: Herding or Anti-Herding? Understanding Investor Behavior in the Baltic States Abstract: This paper investigates market-wide herding behavior in the stock markets of Estonia, Latvia, and Lithuania, employing measures that assess the proximity of market returns to market consensus. Using a survivor-bias-free dataset of daily stock returns, we document significant anti-herding behavior among investors in Latvia and Lithuania throughout the sample period. Results for the Estonian market vary based on the herding measure chosen. Herding dynamics fluctuate over time, with the COVID-19 pandemic increasing the intensity of the effect in Estonia and Lithuania. Moreover, the deterioration of investor sentiment and stronger funding restrictions are found to amplify herding in these two markets. Estonia's market displays asymmetric behavior, with herding being more pronounced during negative market performance. Collectively, these findings are relevant to management practice since they suggest that it is difficult to extract the desired benefits of international diversification in the Baltic region, especially during market downturns. 2025-01-01T00:00:00Z https://hdl.handle.net/10216/170843 Title: Overconfidence vs. Herding: Analyzing Investor Behavior in the Moroccan Retail Trade Sector Abstract: <jats:p>This study looks at overconfidence and herding in the Moroccan stock market, focusing on the retail trade sector. We use daily data from four major stocks; Autohall, Ennakl, Label Vie, and Total Maroc, covering March 2015 to January 2025. Investor behavior is analyzed with regression and rolling-window methods. Overconfidence is tested by seeing how volatility and past returns affect trading volume, while herding is measured using CSAD metrics for both trading volume and returns. The results provide strong evidence of overconfidence, particularly in Label Vie and Total Maroc, where volatility coefficients are significantly positive (ß = 1.52e+06 and ß = 6.17e+05, respectively). These findings confirm that higher volatility encourages excessive trading. Rolling regressions further show that overconfidence is time-varying and becomes more pronounced during volatile market conditions. By contrast, herding behavior appears largely absent. The squared market volume coefficient (ß = -1.512e-12, p = 0.747) and squared return coefficient (ß = 4.46, p < 0.01) indicate that dispersion increases rather than contracts during periods of elevated market activity, contradicting the expectations of herding models. Time-varying t-statistics also remain consistently above -2, confirming the lack of persistent herding across the sample period. Overall, the findings show that Moroccan retail investors are more influenced by their own confidence than by following the crowd.</jats:p> 2025-01-01T00:00:00Z https://hdl.handle.net/10216/170556 Title: SOCIAL MEDIA, MARKET REGULATION AND CEO INFLUENCE: LESSONS FOR MARKET EFFICIENCY Abstract: Social media communication has become increasingly influential in the stock market. Platforms such as X (formerly known as Twitter), Facebook, and Reddit serve as channels for corporate CEOs to share information, analysis, and opinions that can influence the stock prices of the companies they manage. The research this paper is based on tested whether it is possible to obtain abnormal stock trading returns by following Elon Musk's tweets about Tesla. We studied ten years of Elon Musk's tweetsaboutTesla, collecting data on 3,158 tweetsand2,420 stock trading days and identifying 33 events. We employed an event study methodology, utilizing the Five-Factor Model and the Capital AssetPricingModel to estimate Tesla's daily expected returns and assess the statistical significance of Tesla's abnormal stock returns following Elon Musk's tweets. We estimated abnormal returns over the event window and on the event day. We also estimated a logit regression on the ten-year sample period to assess whether the tweets caused aggregate abnormal returns. We conclude that Elon Musk's tweets did not significantly impact Tesla's stock price, suggesting that the market is informationally efficient and that, in recent years, it has not been possible to obtain abnormal returns by trading based on these tweets. Our methodological contribution is isolating tweet-related price reactions by excluding pre-event days, which are usually contaminated by fundamental information, and focusing exclusively on the effects of social media on stock price returns. We contribute to the literature on the relationship between social media and market efficiency, offering valuable insights for investors, regulators, and policymakers. 2025-01-01T00:00:00Z https://hdl.handle.net/10216/170577 Title: Effects of Price Clustering on African Stock Markets Abstract: The phenomenon of price clustering refers to the empirical finding that some prices in financial markets occur significantly more frequently than others. The phenomenon is important theoretically as it challenges the efficient market theory and empirically as it suggests that predictability patterns can be used by investors to devise strategies and investments capable of generating abnormal returns. In this paper, we study the phenomenon for the first time in the context of African markets. Our study includes data from the period spanning 2018-2022 for the stock markets of Egypt, Kenya, Morocco, Nigeria, South Africa, and Tunisia. Our results provide compelling evidence of price clustering within all markets under analysis. Univariate analysis confirms widespread clustering, particularly favoring closing prices ending in zero and five. The results of the multivariate analysis suggest that stocks with higher prices, lower turnover, and lower liquidity tend to exhibit a higher level of clustering. Contrary to the expectations of the Panic Selling Hypothesis, a more intense clustering did not occur during the COVID-19 pandemic. Collectively, our results offer partial support for the Attraction Hypothesis and the Negotiation/Price Resolution Hypothesis. 2025-01-01T00:00:00Z https://hdl.handle.net/10216/165060 Title: Blockchain governance: reducing trusted third parties with decred project 2025-01-29T00:00:00Z https://hdl.handle.net/10216/172248 Title: The uneven implementation of the 4-day workweek: organizational cultures in tension Abstract: PurposeDespite the different scientific contributions about the 4-day workweek, there is a lack of research into the role of organizational cultures in implementing the 4-day workweek. This article addresses that gap, discussing the extent to which specific types of organizational culture favour the experience of implementing the 4-day workweek and the tensions that surround it.Design/methodology/approachThis article is based on a case study exploring how the uneven implementation of a 4-day workweek in a small company relates to organizational cultures and their tense dynamics. Data was collected through semi-structured interviews and an organizational culture assessment instrument.FindingsThis case study reveals that the uneven implementation of the 4-day workweek is favoured by the hybrid organizational culture of a small company, combining tradition and innovation leadership styles. It discusses a double tension between current and preferred organizational cultures, as well as inside the existing hybrid organizational culture, which managed to accommodate both 4-day and 5-day working formats.Originality/valueThis study outlines the underexplored scientific area of organizational cultures in leveraging the 4-day workweek and the tensions that arise from running through it. In addition, it offers insights for organizations and practitioners' debate because it discusses an uneven experience of implementing the 4-day workweek as it includes workers who joined, declined or were excluded from the 4-day format by a unilateral decision of the administration. 2025-01-01T00:00:00Z https://hdl.handle.net/10216/172153 Title: The socioeconomic impact of a music festival on a community: The case of Bons Sons in Cem Soldos village Abstract: Music festivals have historically celebrated regional culture and community (Duffy, 2000). Over time, their commercial aspects have overshadowed community goals, favouring urban areas over rural ones. However, the rise of nostalgic tourism offers hope for rural revitalization. This research examines the Bons Sons Festival, evaluating its cultural, social, and economic impacts through interviews, surveys, and regression analysis. Results indicate that the festival positively impacts the local economy of Cem Soldos village, particularly in accommodation and food services, and fosters community projects throughout the year. 2025-01-01T00:00:00Z https://hdl.handle.net/10216/119110 Title: Consumer brand engagement, satisfaction and brand loyalty: a comparative study between functional and emotional brand relationships Abstract: Purpose - The purpose of this study is to understand differences in consumer brand engagement (CBE) according to the functional or emotional nature of consumer-brand relationships and its direct and/or indirect impact on brand loyalty (BL). Additionally, the study aims to compare CBE and Satisfaction as predictors of BL, considering the two types of consumer-brand relationships. Design/methodology/approach - A cross-sectional survey was applied to two independent samples. Respondents of one of the samples were asked to recall a brand with which they had a functional relationship, while the other respondents were asked to consider a brand with which they had an emotional relationship. To test research hypotheses, a causal model using SEM was developed. Findings - Results validate CBE as a three-dimensional construct, stronger for emotional than functional brand relationships and show its significant direct and indirect impact on BL. Through a comparative analysis, findings also prove that the effects of CBE on BL, directly or indirectly through Satisfaction, are stronger for emotional relationships, while Satisfaction is a stronger direct predictor of BL for functional brand relationships. Originality/value - Addressing calls to focus on the impact of specific brand types on engagement, this study allows a better understanding of the moderating role of functional and emotional relationships on CBE. This study further adds to the existing body of knowledge by establishing the mediating role of Satisfaction and comparing the contribution of CBE and Satisfaction to BL according to the nature of consumer-brand relationships. Overall, our findings enhance knowledge on how consumers engage with and become loyal to brands, offering important implications for brand managers. 2019-01-01T00:00:00Z https://hdl.handle.net/10216/82349 Title: The effect of self-checkout quality on customer satisfaction and repatronage in a retail context Abstract: Self-service technologies (SSTs) are defined as technological interfaces that enable customers to produce a service without direct employee involvement. Among various SSTs, self-checkouts are being tested by grocery stores across the world. However, while most studies focus on SST adoption, there is limited research on its impact on service quality, customer satisfaction, and retention. Our study investigates consumers' assessments of self-checkout in a retail outlet, and its influence on post-usage intentions. The study presents a causal model in order to determine (i) whether consumers evaluate service quality for self-checkout based on five different attributes: speed, ease-of-use, control, reliability, and enjoyment; (ii) whether the evaluation of service quality differs according to demographics and usage frequency; and finally (iii) if service quality delivered by self-checkout relates to overall customer satisfaction and retail patronage. We conclude that successful use of self-checkout may "tie'' consumers to a provider, representing a feature that differentiates a retailer from competitors. 2017-01-01T00:00:00Z https://hdl.handle.net/10216/90444 Title: Graduates' perceptions about labour market competencies: does the type of institution and programme make a difference? 2016-01-01T00:00:00Z https://hdl.handle.net/10216/79703 Title: Unfairness in consumer services: Outcomes of differential treatment of new and existing clients Abstract: In a consumption context, there is a growing interest in understanding unfair behaviour of firms towards customers. Our research focuses on unfairness perceptions driven by differential treatment, particularly through price discrimination, i.e. the practice of charging differential prices to different customers. Our purpose is to investigate the consequences of these practices for unfairness perceptions, satisfaction, trust and patronage, showing a dual perspective: the perceptions of new vs existing clients when they face the advantaged or disadvantaged conditions. A survey-based experimental design approach was used. We conclude that unfairness perception is stronger for existing than for new clients, prompting negative attitudinal and behavioural consequences when the former are exposed to disadvantaged conditions in relation to the latter. Our study aims to provide marketers with a perspective on the pitfalls related to differential treatment between present and prospective clients, with implications in terms of design and implementation of customer management strategies. 2016-01-01T00:00:00Z https://hdl.handle.net/10216/81646 Title: How to engage customers in co-creation: customers' motivations for collaborative innovation Abstract: The term "customer engagement" (CE) has been increasingly used in academic marketing literature. Empowered by the rise of the internet, customers are no longer a "passive audience" but "active co-producers" and engage in behaviours that strengthen their relationship with the product, company or brand, such as collaborating to co-create value through innovation. However, few studies exist on collaborative innovation and how to engage customers in co-creation, namely in specific virtual environments. Drawing on insights from product innovation and virtual communities, our study seeks to understand why customers participate voluntary and freely in co-creation online activities, by testing a conceptual model which considers an integrated set of motivations for members to engage in collaborative innovation. On a managerial level, our study intends to provide valuable insights to firms on how to create an experience to engage consumers in co-creation in virtual communities. 2016-01-01T00:00:00Z https://hdl.handle.net/10216/170128 Title: Olhares e perspectivas sobre educação e imigração em Portugal: do Ensino Básico ao Ensino Superior 2025-01-01T00:00:00Z https://hdl.handle.net/10216/163488 Title: Brand Love, Attitude, and Environmental Cause Knowledge: Sustainable Blue Jeans Consumer Behavior Abstract: A blue jeans brand committed to the environmental cause could position itself as unique and socially responsible and attract environmentally driven consumers. This research study examines the relationship between brand love and consumers environmental cause knowledge and their willingness to recommend and pay a premium for sustainable blue jeans. To this end, this cross-sectional study comprises a snowball convenience sample of 978 Portuguese respondents, whose data were collected from December 2022 to January 2023. Positive associations between self-expression, brand love, loyalty, environmental cause knowledge, positive word-of-mouth, and willingness to pay a premium for sustainable blue jeans stand out. There are differences in the willingness to pay a premium among generations, education levels, and consumers who are aware of sustainable line extensions and those who are not. The results may be helpful for brands, suggesting their communication should focus on creating increased proximity to consumers by enhancing their values and seeking to link their brands to intrinsic benefits and environmental stakes. This is the first study to incorporate knowledge of the environmental cause into a model linking brand love, brand loyalty, positive word-of-mouth, and willingness to pay a premium for sustainable blue jeans. 2024-01-01T00:00:00Z
