RESUMO
Gamification involves using game design elements in non-game contexts. It is an emerging strategy that, being able to motivate consumer engagement with brands, has been increasingly used by companies in marketing activities. Recently, the application of gamification to marketing has become increasingly popular, with an increasing amount of research outputs. However, a clear overview of the field, a theoretical orientation or an agenda for research are still missing, which justifies the analysis of the existing literature joining these two fields of research. The motivation for conducting this review was twofold: Firstly, it is helpful to attain a broad overview of this developing field, synthesizing the existing knowledge in a structured way, understanding how gamification research in marketing has progressed and what type of knowledge has been acquired; secondly, it allows us to provide valuable information that will guide future research. Thus, this study provides a hybrid review, which integrates a bibliometric and TCCM analysis, of gamification in marketing by analyzing 114 articles. The data was retrieved from the Scopus scientific database. The bibliometric analysis showed the existence of 8 clusters, mostly representing current areas of research. It was found that the focus of the literature, so far, has been on studying which game elements should be implemented in a gamification system, as well as examining the impact of gamification experiences on engagement and consumer's behaviors. The TCCM analysis revealed the major theories and methodological approaches explored in published articles. The use of self-determination theory and quantitative methodology, based on primary data using online surveys, stands out. These complementary analyzes allowed to provide future research directions to scholars and practitioners working in this domain, promoting the advancement of scientific knowledge, contextual relevance and methodological rigor. Moreover, this review also helps marketers make more informed strategic decisions and supports successful gamification design.
RESUMO
BACKGROUND: Unbiased analysis of the impact of adaptive radiotherapy (ART) is necessary to evaluate dosimetric benefit and optimize clinics' workflows. The aim of the study was to assess the need for adaptive radiotherapy (ART) in head and neck (H&N) cancer patients using an automatic planning tool in a retrospective planning study. MATERIALS AND METHODS: Thirty H&N patients treated with adaptive radiotherapy were analysed. Patients had a CT scan for treatment planning and a verification CT during treatment according to the clinic's protocol. Considering these images, three plans were retrospectively generated using the iCycle tool to simulate the scenarios with and without adaptation: 1) the optimized plan based on the planning CT; 2) the optimized plan based on the verification CT (ART-plan); 3) the plan obtained by considering treatment plan 1 re-calculated in the verification CT (non-ART plan). The dosimetric endpoints for both target volumes and OAR were compared between scenarios 2 and 3 and the SPIDERplan used to evaluate plan quality. RESULTS: The most significant impact of ART was found for the PTVs, which demonstrated decreased D98% in the non-ART plan. A general increase in the dose was observed for the OAR but only the spinal cord showed a statistical significance. The SPIDERplan analysis indicated an overall loss of plan quality in the absence of ART. CONCLUSION: These results confirm the advantages of ART in H&N patients, especially for the coverage of target volumes. The usage of an automatic planning tool reduces planner-induced bias in the results, guaranteeing that the observed changes derive from the application of ART.
