- Servant leaders promoting team contextual ambidexterity through team behavioral integrationPublication . Sousa, Milton; Rego, Arménio; Cunha, Miguel Pina e; Dierendonck, Dirk vanWe investigate how servant leadership promotes team contextual ambidexterity via team behavioral integration from a conservation of resources theory perspective, and how such an indirect effect is conditional on two boundary conditions: the “climate strength” of servant leadership and of team behavioral integration. By climate strength we refer to the degree of agreement or consensus among team members regarding those two constructs. Findings from a field study and an experiment indicate that (a) servant leaders foster team contextual ambidexterity by cultivating a supportive context of team behavioral integration, and (b) this indirect effect is amplified when within-team agreement (i.e., the climate strength of servant leadership and team behavioral integration) is higher. We contribute to identifying the micro-foundations of organizational ambidexterity at the team level and exploring why, how and when servant leadership influences such team outcomes. Furthermore, drawing on both conceptual work and empirical evidence, we emphasize the underexplored role of “climate strength” in shaping team contextual ambidexterity through its underlying mechanisms.
- Let's get ready to rumble: personality and the architecture of sport fandomPublication . Gruda, Dritjon; Simha, AdityaWho watches sport, and what does personality reveal about how fandom is expressed? Using Facebook status updates and self-reported Big Five scores of 6246 users across 17 sports, we show that personality leaves a small but consistent imprint on the expression of sport fandom while barely predicting which sport a person watches. Personality maps onto sport attributes more than sport identities: less agreeable users favored high-contact, high-risk sports and extraverts favored larger-team sports. The breadth of a person's viewing was associated with Extraversion rather than Openness, contrary to the cultural omnivore hypothesis. Fans' own words, scored for sentiment and for motives with a validated language-model classifier, show that personality predicts the intensity and motives of expressed fandom (drama, escape, social connection). These associations hold when posting volume and inferred age and gender are controlled, and we found no reliable evidence that inferred gender moderates them. Personality shapes the expression of engagement more than taste in sports.
- A systematic literature review of barriers to analytics adoption in supply chain decision-makingPublication . Baptista, Hermenegildo D.; Gonçalves, João N. C.; Carvalho, M. SameiroThe growing demand for resilient, proactive, and intelligent supply chains (SCs) has increased the adoption of analytics to support operational, tactical, and strategic decision-making. Despite the rapid growth of analytics applications in supply chain management (SCM), many initiatives remain confined to theoretical or experimental contexts and face significant challenges in real-world implementation. Existing literature has predominantly focused on methodological advancements and performance improvements, while barriers to implementation are often treated as secondary concerns rather than structural constraints that may inhibit adoption. This study examines barriers to the adoption of analytics in SCM through a systematic literature review complemented by grey literature. Based on the analysis of 464 papers, a taxonomy of barriers was developed, comprising six categories: organizational, technological, data-related, modeling, regulatory and ethical, and people-related. The findings show that these barriers are highly interdependent and generate compatibilities and trade-offs, where improvements in one dimension may mitigate or intensify constraints in another. The integration of grey literature supported the development of a multilayered framework that conceptualizes analytics adoption as holistic and interdependent process composed of three interconnected layers: (i) a strategic layer related to alignment, direction, and value orientation; (ii) a capability layer derived from the six barrier categories and representing the organizational capabilities required to support analytics adoption; and (iii) an operationalization layer associated with process integration, scalability, and effective analytics use within SC workflows. Finally, our study outlines future research directions and managerial implications to support the adoption of analytics in SCM.
- From numbers to choice: how numerical sustainability claims shape visual attention and purchase decisions in fashionPublication . Tortajada, Elena Gasulla; Duarte, Paulo; Silva, Susana C.; Bigné, EnriqueSustainability information is difficult for consumers to evaluate because environmental performance represents a credence attribute. Although numerical sustainability claims have been shown to improve consumers' perceptions of sustainability communication, little is known about whether they influence product choice under realistic marketplace trade-offs or through which decision processes these effects emerge. Drawing on signaling theory, this research examines whether numerical sustainability claims function as stronger marketplace signals and investigates how visual attention is associated with their influence on consumer choice. Two complementary studies were conducted: a choice-based conjoint experiment (N = 512) examining product choice and willingness to pay, and an eye-tracking experiment (N = 45) investigating visual attention during product evaluation. Results indicate that numerical sustainability claims were associated with higher consumer preference and willingness to pay than equivalent non-numerical claims. Eye-tracking results showed that although numerical claims attracted greater visual attention, attention to the claims alone did not explain product choice. Instead, numerical claims were associated with broader visual attention during product evaluation. The findings suggest that numerical sustainability claims help translate sustainability communication into consumer choice under competitive marketplace settings.
- Organizações de economia social: o que as distingue e como podem ser sustentáveisPublication . Mendes, Américo M. S. CarvalhoNeste artigo começa-se por fazer uma análise crítica do conceito de “organizações sem fins lucrativos” tal como tem sido proposto pelo Center for Civil Society Studies da Universidade de John Hopkins e do conceito de “sector da economia social” tal como tem sido proposto pelo CIRIEC. Em alternativa propõe-se um conceito de organizações de economia social fundado numa definição económica dos seus produtos e dos factores utilizados na sua produção. Esta definição é, depois, desenvolvida identificando várias especificidades económicas destas organizações com relevância para a sua sustentabilidade. Na parte final do artigo passam-se em revista vários factores que podem contribuir para essa sustentabilidade.

- Mapping customer experience through mystery shopping: a case study in automotive dealershipsPublication . Silva, Susana C.; Lisboa, Ana; Coelho, Luana A.Purpose: This study investigates mystery shopping as a diagnostic and strategic tool for assessing customer experience across the automotive retail customer journey. Design/methodology/approach: The research adopts a case study methodology, using three sequential mystery shopper evaluations across a car-brand dealership network. It applies a structured assessment model across pre-visit, visit and post-visit stages. Findings: Service-quality scores generally improved over time, with significant gains observed in needs identification, vehicle presentation and overall score. Quartile analyses showed that high-performing dealerships consistently outperformed lower performers, while top improvers, though initially lower-scoring, demonstrated substantial gains over time. Comparisons with real net promoter score data indicated that mystery shopping assessments became increasingly aligned with customer-reported outcomes, reflecting improved calibration across rounds. Research limitations/implications: Limitations include the absence of purchase intention assessment and limited scoring scale granularity. Future research should expand the framework and integrate other evaluative tools. Practical implications: Mystery shopping provides actionable insights for sales training, customer experience strategy and operational consistency across dealerships. Social implications: This study introduces a structured, longitudinal mystery shopping framework that captures customer experience across time and touchpoints, extending beyond traditional one-off or compliance-focused applications. It contributes theoretically by operationalizing customer experience as an observer-based, journey-centric approach, complementing self-reported service quality assessments and offering a repeatable method for longitudinal CX evaluation.

- Spirit of the hawk: colonial intensity and alcohol use disorders across 178 countriesPublication . Zadegan, Milad Sharafi; Gruda, DritjonQualitative research links colonial history to alcohol-related harms in specific populations, and econometric studies show that colonial institutions shape long-run health trajectories, yet no study has connected these literatures by testing whether colonial intensity predicts national-level alcohol outcomes in a spatially explicit panel framework. We construct a colonial intensity composite (the duration of colonial rule weighted by colony type—extractive versus settler) from COLDAT 3.0 and estimate panel Spatial Durbin Models on 178 countries over 21 years (2000–2020), using geographic contiguity and shared-colonizer spatial weights across four WHO alcohol outcomes. Colonial intensity shows a significant positive direct association with alcohol use disorder (AUD) prevalence across all eight specifications (0.065–0.238 percentage points per unit), accompanied by negative spillover effects (associations transmitted to geographically neighbouring or co-colonized countries). The AUD association emerges only after controlling for cultural confounders (suppression effect) and shows no temporal decay, while consumption effects weaken over time—a pattern consistent with intergenerational trauma persistence. Effects concentrate in British colonies. Standard alcohol policies reduce consumption but not AUD, suggesting regulatory tools alone cannot close the colonial legacy gap in disorder prevalence. These findings provide the first large-scale quantitative evidence linking colonial intensity to contemporary AUD.
- Coopetition and innovation: a review and research agendaPublication . Corbo, Leonardo; Kraus, Sascha; Vlačić, Božidar; Dabić, Marina; Caputo, Andrea; Pellegrini, Massimiliano M.The proliferation of research on innovation-related coopetition calls for a more unified understanding of the current state of knowledge in this domain. Previous reviews on coopetition, however, fall short when it comes to putting innovation at the core of their analysis, often relegating the topic to one of the research themes/dimensions of coopetition, or considering innovation to be a promising area for future research. We fill this gap by systematically reviewing two decades of research on coopetition and innovation. We apply Multiple Correspondence Analysis (MCA) methods to a sample of 128 articles from academic journals published in the field of coopetition and innovation, revealing the major research themes, the theories and methods used, the levels of analysis, and the contexts explored. The holistic representation of coopetition and innovation research hinges upon multiple theories, including the resource-based view, the knowledge-based view, the network view, and the behavioral view, while predominantly focusing on strategy; innovativeness; value creation, appropriation and performance; appropriability and protection; and organizational culture. Given the increasing scholarly interest in both coopetition and innovation, this study proposes fruitful research avenues, and discusses their implications for both theory and practice.
- Capital structure adjustments of Hotel SMEs in Portugal’s hospitality industry during the COVID-19 pandemicPublication . Palminha, Maria Francisca Gomes de Castro Coelho; Manoel, Aviner Augusto Silva; Ames, Alice CarolinaThe COVID-19 pandemic triggered an unprecedented economic shock, disrupting business operations and demand across sectors. This study examines the impact of the COVID-19 pandemic on the capital structure of small and medium-sized enterprises (SMEs) in the Portuguese hotel sector, a core segment of the hospitality industry and one of the most severely affected by the crisis. Using a panel dataset of private hotel firms in Portugal, we find a significant reduction in total debt during the pandemic. Decomposing debt by maturity reveals that firms reduced short-term borrowing while expanding long-term financing, indicating a recomposition of the debt structure during the pandemic. Furthermore, when firms are segmented by size, the reduction in total leverage was concentrated among smaller, financially constrained firms, while the expansion in long-term financing was observed among larger, financially unconstrained firms. A further decomposition of total liabilities into financial and operating components reveals that financial and operating liabilities responded in opposite directions during the pandemic: operating liabilities contracted, while financial liabilities, notably long-term financial debt, increased. This study contributes to the literature on capital structure, corporate finance, and crisis management by providing one of the first empirical assessments of COVID-19's effects on SME financing in a tourism-dependent, bank-reliant economy, a context that remains understudied. It also extends prior research by focusing on private rather than public firms. By examining a highly vulnerable sector, the findings offer insights into financial resilience during crises and provide policy implications for improving liquidity access and strengthening financial stability among tourism-dependent hotel SMEs.
