Abstract
This article examines the impact of digital influencers ' recommendations, especially Instagrammers, on the pur-chase intention of healthy food. In addition to the direct influence of source credibility on behavioral intention, the study also examines the influence of self-brand congruence and consumers' involvement with healthy food on purchase intention. To test research hypotheses, a quantitative study was conducted with 221 Portuguese con-sumers. High and low involvement with healthy food groups were classified by K-Means Clustering, and the analysis of the structure and the measurement models was performed by using Smart-PLS software. The results confirmed that Instagrammers' credibility drives self-brand congruence and purchase intention for healthy food. It was also confirmed that the involvement with healthy food moderates the influence of self-brand congruity and Instagrammers' credibility on consumers' intention to purchase healthy food, and that brand self-congruence partially mediates the influence of Instagrammers' credibility on purchase intention. Overall, this work offers rel-evant insights for both marketing managers and researchers, as it demonstrates the importance of considering the indirect effects of source credibility on purchase intention of healthy food and of comparing consumers with high and low product involvement to effectively evaluate the impact of digital influencers' in healthy food endorsement.

Abstract
The assertive online strategies of Portuguese luxury fashion brands/designers (LFBDs) are essential for managers to succeed in the digital medium and establish long-lasting relationships with clients. This paper explores the challenges in digitizing all the dis-tinctive elements of a luxury fashion brand: the product characteristics, the luxury atmosphere, the personalization of the service, and the services provided. Fourteen Portuguese brands/designers were selected for content analysis. According to Hansen's framework, 43% of Portuguese LFBDs fail to share information about their com-panies on their websites, and only 43% include promotions. Only 36% have a com-munity outside the websites, compared to 93% of the international luxury fashion brands. Moreover, Portuguese websites lack 360 & DEG; technology and augmented reality. Considering the Digital Visual Merchandising - MVD Grid, Portuguese LFBDs do not allow multiple zooms and 2D F/T cursor change, while international brands feature these tools. Regarding the Social Media Performance Analysis Grid, the global aver-age engagement rate of Portuguese LFBDs on Facebook is 0.19% and on Instagram - 0.89%. According to Social Media Content Analysis Grid, Portuguese brands bet a lot on sharing content in story format, mainly on Instagram; however, Facebook has a higher network value. Therefore, the findings show that Portuguese LFBDs should be present and market their products online. This online presence must be supported by a multi-channel strategy while maintaining luxury product characteristics and elements of differentiation.

Abstract
The main objective of this article is to investigate the factors that influence customers' intention to reuse chatbot-based services. The study employs a combination of the technology acceptance model (TAM) with other contributions in the literature to develop a theoretical model that predicts and explains customers' intention to reuse chatbots. The research uses structural equation modeling (PLS-SEM) to test the proposed hypotheses. Data collected from 201 chatbot users among Portuguese consumers were analyzed, and the results showed that user satisfaction, perceived usefulness, and subjective norm are significant predictors of chatbot reuse intentions. Additionally, the findings indicated that perceived usefulness, perceived ease of use, and trust have a positive impact on attitudes toward using chatbots. Trust was found to have a significant impact on perceived usefulness, user satisfaction, and attitudes toward using chatbots. However, there was no significant effect of attitude toward using chatbots, perceived ease of use, trust, and perceived social presence on reuse intentions. The article concludes with theoretical contributions and recommendations for managers.

Abstract
This study aims to examine consumer intention to purchase eco-friendly, handcrafted fashion products made from upcycled clothing and traditional Indonesian batik fabric. Data were collected via an online questionnaire with 289 participants, including both Indonesian and non-Indonesian consumers. The hypotheses were tested using structural equation modeling in SmartPLS 3. The results showed that fashion motivation and perceived value positively impacted the intention to purchase this type of product for personal use and for gifting. The perceived price had a positive effect on purchase intention for gifting. Altruistic motivations affected attitudes but not purchase intentions. Differences were identified between national and foreign consumers regarding the impact of price perception on attitudes and personal purchase intentions. The study provides practical implications for small businesses, artisan crafts, and entrepreneurs.
