C.; Pereira, Â.; Saraiva, M.; Canas, J. M.; Lopes da Costa, R. Resumo: Purpose This study synthesizes the fragmented literature on the impact of sustainable marketing on firm performance. Despite growing corporate interest, research findings remain contradictory. This paper aims to map the evolution of the field, identify key mediating factors, and propose a novel conceptual framework for understanding how sustainable marketing initiatives can drive business success. Methodology A bibliometric analysis was conducted on a final sample of 55 documents indexed in the Scopus database from 2013 to 2023. The study utilized VOSviewer to map keyword co-occurrences, identifying four central thematic clusters: sustainability, sustainable development, marketing strategy, and green marketing and supply chain management. Findings Results indicate that sustainable marketing generally has a positive long-term impact on performance. However, this relationship is not direct; it is mediated by factors such as green reputation, consumer trust, innovation, and marketing communication capabilities, while being hindered by barriers like greenwashing and implementation costs. Success requires an integrated approach that adapts to regional contexts and consumer environmental awareness. Practical and Research Implications The study proposes a novel conceptual framework that organizes variables into a logical structure linking strategic antecedents, mediating mechanisms, and multi-dimensional outcomes. Practical recommendations include integrating sustainable marketing into traditional strategies, investing in green supply chain management, and ensuring transparency. The research highlights the need for adaptive approaches and suggests future studies incorporate additional databases and empirical testing. Originality/Value This study provides the first bibliometric analysis to synthesize the relationship between sustainable marketing and firm performance into a structured conceptual framework. It integrates fragmented findings from 2013–2023 into a coherent body of knowledge, enriching theoretical understanding by linking results to the Resource-Based View (RBV) and Stakeholder Theory. It offers a new theoretical lens for the field and translates academic findings into practical managerial insights. 2026-01-01T00:00:00Z http://hdl.handle.net/10071/35331 Título próprio: Parcel delivery services: A sectorization approach with simulation Autoria: Lopes, I.; Rodrigues, A.; Ozturk, E.; Ferreira, J.; Nunes, A. C.; Rocha, P.; Oliveira, C. Editor: João Paulo Almeida; Filipe Pereira e Alvelos; Jorge Orestes Cerdeira; Samuel Moniz; Cristina Requejo Resumo: Sectorization problems, also known as districting or territory design, deal with grouping a set of previously defined basic units, such as points or small geographical areas, into a fixed number of sectors or responsibility areas. Usually, there are multiple criteria to be satisfied regarding the geographic characteristics of the territory or the planning purposes. This work addresses a case study of parcel delivery services in the region of Porto, Portugal. Using knowledge about the daily demand in each basic unit (7-digit postal code), the authors analysed data and used it to simulate dynamically new daily demands according to the relative frequency of service in each basic unit and the statistical distribution of the number of parcels to be delivered in each basic unit. The sectorization of the postal codes is solved independently considering two objectives (equilibrium and compactness) using Non-dominated Sorting Genetic Algorithm-II (NSGA-II) implemented in Python. 2023-01-01T00:00:00Z http://hdl.handle.net/10071/31850 Título próprio: Network structure of online customer reviews and online hotel reviews: A systematic literature review Autoria: Pestana, M. H.; Gageiro, M.; Santos, J. A. C.; Santos, M. C. Resumo: This study conducts a bibliometric analysis of online customer and hotel review research, aiming to provide insights into where each field comes from, stands now and ought to go in the future. In particular, this study examines how the existing research on online customer reviews can benefit future hotel review research. Data collected from Web-of-Science and Scopus created an expanded network of 797 core articles and 19,374 citations to identify intellectual structures, developing trends, and future research gaps. This study offers a visual overview of journals, institutions, countries, research themes and authors to assess the overall directions hotels can take. It underscores the necessity for rigorous and relevant research amid the proliferation of online reviews and emphasises the imperative for academia to bridge the gap between theoretical insights and practical applications within the dynamic tourism industry. This study provides researchers and industry professionals with useful tools to understand and deal with the complexities of online reviews. It also highlights the important role these reviews play in shaping the future of tourism strategies. 2024-01-01T00:00:00Z http://hdl.handle.net/10071/31589 Título próprio: D3S: Decision support system for sectorization Autoria: Öztürk, E. G.; Rocha, P.; Rodrigues, A. M.; Ferreira, J. S.; Lopes, C.; Oliveira, C.; Nunes, A. C. Resumo: Sectorization problems refer to dividing a large set, area, or network into smaller parts concerning one or more objectives. A decision support system (DSS) is a relevant tool for solving these problems, improving optimisation procedures, and finding feasible solutions more efficiently. This paper presents a new web-based Decision Support System for Sectorization (D3S). D3S is designed to solve sectorization problems in various areas, such as school and health districting, designing sales territories and maintenance operation zones, or political districting. D3S bridges the gap between sectorization problems and a state-of-the-art decision support tool due to its broad design. The paper aims to present generic and technical attributes of D3S by providing detailed information regarding the problem-solution approach (based on Evolutionary Algorithms), objectives (most common in sectorization), constraints, structure, and performance. 2024-01-01T00:00:00Z
