Abstract
In this paper we analyze the relationship between the marketing mix and new product diffusion models. The goal is to obtain a general new product diffusion model that incorporates the classic 4Ps model of the Marketing Mix: Product, Price, Place, Promotion. An empirical study was conducted using mobile broadband adoption data in Japan. © 2022 Elsevier B.V.. All rights reserved.

Abstract
Churn and how to deal with it is an essential issue in the telecommunications sector. Within the scope of actionable knowledge, we argue that it is crucial to find effective personalized interventions that can lead to a reduction in dropouts and that, at the same time, make it possible to determine the causal effect of these interventions. Considering an intervention that encourages clients to opt for a longer-term contract for benefits, we used Uplift modeling and the Transformed Outcome Approach as a machine learning-based technique for individual-level prediction. The result is actionable profiles of persuadable customers that increase retention and strike the right balance between the campaign budget.

Abstract
The digital learning transformation brings the extension of the traditional libraries to online repositories. Learning object repositories are employed to deliver several functionalities related to the learning object's lifecycle. However, these educational resources usually are not described effectively, lacking, for example, educational metadata and learning goals. Then, metadata incompleteness limits the quality of the services, such as search and recommendation, resulting in educational objects that do not have a proper role in teaching/learning environments. This work proposes to bring an active role to all educational resources, acting on the analysis generated from the usage statistics. To achieve this goal, we created a multi-agent architecture that complements the common repository's functionalities to improve learning and teaching experiences. We intend to use this architecture on a repository focused on ocean literacy learning objects. This paper presents some steps toward this goal by enhancing, when needed, the repository to adapt itself.

Abstract
Customer retention is nowadays a challenge that requires concrete and personalized actions. Traditional data mining studies focused on predictive analytics, neglecting the business domain. This work aims to present an actionable knowledge discovery based on specific, actionable attributes and measuring of their effects. It is common to use matching, and propensity score approaches in healthcare to evaluate causality. After performing matching using the actionable attributes in this analysis, the causal effect is quantified. This work concludes that the difference between having a yearly contract versus having a monthly contract affects the churn of around 34%.

Abstract
The administrative management of a basketball club, even of small size, presents several challenges, with one of the most critical being the efficient organization of all generated information and documentation. In order to meet all the requirements surrounding sports management, the use of information systems in sports is indispensable for the success of an organization. This research involves modeling an information system in the form of a web application for the administrative content management of a sports club, ensuring the efficient organization and availability of all its information. This activity includes identifying the necessary resources and investment, developing a prototype, and evaluating potential impacts.;A gestão administrativa de um clube de basquetebol, mesmo que de pequena dimensão, apresenta vários desafios, sendo que um dos mais críticos é a organização eficiente de toda a informação e documentação gerada. De forma a responder a todas as exigências que rodeiam a gestão desportiva, o uso de sistemas de informação no desporto é indispensável para o sucesso de uma organização. Esta investigação passa por efetuar a modelação de um sistema de informação, em forma de aplicação web, para gestão do conteúdo administrativo de um clube desportivo, de modo a garantir a organização e disponibilização de toda a sua informação de forma eficiente. Esta atividade deverá compreender a identificação dos recursos e investimento necessários, o desenvolvimento de um protótipo e a avaliação dos potenciais impactos.
