- Be personal, but not too personal: necessary condition analysis of young consumers' reactions to personalized Instagram adsPublication . Lisboa, Ana; Meneses, Raquel; Silva, Susana C.; Santos, Carolina FreirePurpose: Nowadays, personalization is key to connecting with consumers. However, it comes with a caveat: privacy concerns, which lead to a personalization-privacy paradox. This study aims to examine how young consumers respond to personalized digital advertising, considering both the benefits and potential downsides. It investigates how these perceptions shape affective ad involvement and how that, in turn, influences key online behaviours. Design/methodology/approach: Data from an online survey of Instagram consumers were analysed using necessary condition analysis. Findings: Results show that achieving high affective involvement requires communication to be perceived as highly personalized, highly useful and minimally intrusive. Affective involvement is a necessary but not sufficient condition for purchase intention. Similarly, positive eWOM is necessary to drive purchase intention, while negative eWOM does not significantly deter it. Originality/value: The research examines both bright and dark sides of personalized advertising from the perspective of young consumers, offering a balanced view. By applying a necessary conditions analysis approach, it identifies the minimum levels of perceived benefits and concerns that must be met/avoided to trigger young consumers’ emotional engagement, sharing behaviour and purchase intentions. This approach provides more actionable and precise insights for designing digital marketing strategies that resonate with today’s privacy-aware, tech-savvy youth.
- Cross-cultural validation of the malevolent creativity behavior scale in 7 countriesPublication . Ramos-Vera, Cristian; Machado, Gisele Magarotto; Gruda, Dritjon; Fu, Hongyu; Olivera-Cercado, Royer; Hualparuca-Olivera, Luis; Amoako, Bernard Mensah; Mahama, Inuusah; Anthony, Ireri; Farias, Eliana Santos de; Nakano, Tatiana de Cassia; Campos, Carolina Rosa; Bonfá-Araujo, BrunoThis study examined the psychometric properties and cross-cultural validity of the Malevolent Creativity Behavior Scale (MCBS). A total of 2937 participants from Brazil, China, Ghana, Kenya, Peru, the United Kingdom, and the United States completed the 13-item MCBS. Confirmatory factor analyses compared multiple factor structures (unidimensional, three-factor, hierarchical, and bifactor), and measurement invariance was tested both across countries and by sex. The original three-factor solution demonstrated a generally acceptable fit. The measurement invariance findings indicated that the MCBS retains stable thresholds and factor loadings across groups, supporting the meaningfulness of comparisons. No significant item bias emerged by sex. However, most MCBS items do not reference novelty, a defining feature of creativity, posing the concern that the MCBS focuses more on malevolent ideation or antagonistic behaviors rather than creative malevolent processes. Overall, the results underscore the MCBS as a reliable tool for measuring harmful and creative behaviors in diverse cultural and demographic contexts. These findings contribute to the growing understanding of how malevolent creativity manifests and can be measured worldwide.
- Decomposing spatial effects of state-level health outcomes: a methodological demonstration and re-analysisPublication . Gruda, Dritjon; Hanges, Paul; McCleskey, Jim A.While spatial autoregressive (SAR) models are increasingly used in population-level psychological studies, researchers often overlook the crucial step of parsing effects into direct, indirect and total impacts, a standard practice in spatial econometrics. In this paper, we demonstrate the necessity of this practice by re-analyzing Gruda et al.'s (2024) U.S. Dark-Triad and health dataset with heteroskedasticity-robust SAR models and full impact decomposition, revealing significant changes. The previously observed direct protective effect of state-level narcissism on hypertension mortality disappeared when accounting for interstate spillovers. Conversely, the association with lower cancer prevalence and depression strengthened. Several health-behaviour findings reversed direction, indicating naïve regressions conflated within- and between-state effects. Machiavellianism and psychopathy coefficients also shifted. These results demonstrate that spatial spillovers can dilute, negate or reverse local effects, cautioning against policy inferences based solely on direct estimates.
- The socioeconomic impact of a music festival on a community: the case of Bons Sons in Cem Soldos villagePublication . Teixeira, Maria João; Coelho, Sandra Lima; Cunha, Mariana; Seixas, CarlosMusic 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.
- Normalizing VES production functions: extending the supply-side system approachPublication . Río, Fernando del; Rebelo, FranciscoThis paper extends the Klump et al. (2007) normalization procedure to Variable Elasticity of Substitution (VES) production functions. Normalization addresses identification issues in VES model estimation, allowing joint estimation of substitution elasticities and factor-augmenting technical change, while offering a tractable extension of the normalized supply-side system that bridges the gap between CES and more flexible VES specifications.
- Eu-nique perspectives? Analysing contrasting positions on the russo-ukrainian conflict within the EUPublication . Ramos, Matilde; Sá, Filipa; Silva, Noa; Resende, Mariana; Castro, IsabellaThis research examines the various positions adopted by the European Union (EU) Member States in response to the ongoing Russo-Ukrainian conflict, since its reignition on February 24th, 2022. The study is based on a content discourse analysis of speeches and official statements released by individual EU Member States, namely Poland, owing to its historical relations with the Eastern Bloc and its noteworthiness in accommodating refugees; followed by Germany and its pivotal role in providing military equipment to Ukraine; and lastly, Hungary, due to the contentious public statements issued by its Prime Minister, Viktor Orbán. The analysis is complemented by an examination of the broader foreign policy orientations of these countries that shape their responses. The primary aim is to assess whether the Union maintains a cohesive consensus on the conflict or if diverging positions weaken its support for Ukraine. Ultimately, through a juxtaposition of opinions issued by Poland, Germany, and Hungary against the overall EU stance, we conclude that the European Union’s support for Ukraine is not as robust and cohesive as expected.
- Channel integration puzzle: internal obstacles, industry drivers and omnichannel capabilitiesPublication . Hajdas, Monika; Radomska, Joanna; Kawa, Arkadiusz; Klimas, Patrycja; Silva, Susana C.Purpose – In this paper, we aim to advance the research on how companies navigate channel integration by examining the internal and external challenges they encounter. Specifically, we investigate how internal obstacles and external industry drivers affect the level of channel integration. Design/methodology/approach – In our quantitative study, we collected the relevant data from 412 firms operating in over 20 diverse industries and offering both online and offline channels. We also explore how organizational omnichannel capabilities moderate the relation between internal and external factors and the level of channel integration. Findings – Our results indicate that channel integration is hindered by internal barriers, including limitations in operational efficiency, strategy and organizational culture. Additionally, external pressures stemming from industry-specific factors contribute to these challenges. Conversely, positive influences may arise from micro- environmental factors, such as an existing customer base already literate with omnichannel solutions or competitors advanced in omnichannel strategies. Originality/value – To evaluate the effects of channel integration, we examine its influence on performance across multiple dimensions (short-term, long-term and comparative), extending prior research that has predominantly emphasized short-term performance metrics.

- Quit playing games with our lives: layoffs predict road traffic fatalitiesPublication . Gruda, Dritjon; Gonçalves, Ricardo; Zadegan, Milad SharafiEconomic downturns are typically associated with fewer traffic accidents due to reduced driving. However, the psychological and social shocks of sudden job loss may counterintuitively increase risk on the road. In this paper, we examine whether mass layoffs announcements are associated with short-term increases in traffic fatalities in the United States using spatial autoregressive models. Merging monthly U.S. county-level data on mass layoffs with motor vehicle fatality counts, we find a significant uptick in monthly traffic fatalities following major layoff events. This pattern persists after accounting for seasonal trends and regional factors, including unemployment rates and weather conditions. These findings suggest that the stress and disruption caused by mass layoffs can have deadly consequences beyond the workplace. We discuss psychological mechanisms (e.g., distress-related driving impairment) and implications linked to short-term rises in traffic fatalities and public health implications for fatal crash risk.
