Abstract
During the last decades, local, regional, and national governments promoted the development of smart cities, aiming the integration of traditional urban infrastructures and information technologies to provide high quality and sustainable urban services. Smart cities' implementations may change the way the individuals experience the urban spaces. Looking specifically to older adults, smart cities' applications have the potential of promoting their autonomy, independence, safety, well-being, social participation, and inclusion. This paper presents a survey of the scientific literature aiming to analyse current evidence related to smart cities' applications to support older adults and to identify issues for future research.

Abstract
The urban development model practiced in the past has proved to be unsustainable. Due to this fact, cities such as Rio de Janeiro, with high population density, mainly regarding precarious settlements, need immediate practical actions to become more sustainable. The insufficiency of planning and investments contributed to the city occupying the 8th position of the most vulnerable cities in the world, triggering the primary motivation of the research study. Therefore, the leading research focused on exploring how sustainable habitats could contribute to Rio de Janeiro becoming more sustainable. A document analysis was carried out, and semi-structured interviews were designed, making it possible to identify projects to create sustainable habitats for Rio de Janeiro that can serve as benchmarks and listen to the engineers and architects regarding the importance of the sustainable building. Thus, consonant to structural changes in thinking, producing, consuming, and living, it was also possible to identify the main contributions of sustainable habitats to the city, classifying them within the pillars of sustainability.

Abstract
An increased risk of developing stress, musculoskeletal and cardiovascular diseases, rhinitis, skin and eye irri-tations and headaches has been particularly reported among office workers. Some of these complaints have been linked to the existence of poor indoor environmental quality (IEQ) in the workplaces. In this context, inter-vention studies can offer new insights to tackle poor IEQ issues and to identify effective measures to reduce IEQ-related risks. This review summarizes the main characteristics of environmental intervention studies that have been performed in office settings and the respective findings on the beneficial effects on the promotion of health, well-being, comfort, and productivity among office workers. The study design followed PRISMA guidelines and the search for peer-review articles was conducted in Scopus, Web of Science, PubMed, and Cochrane Library databases. Firstly, 513 records were identified, resulting in 23 articles included in the review after the application of the study eligibility criteria and identification of additional important works within the subject. The revised experimental studies were mainly focused on changes in ventilation systems via replacement of air filters and modifications in the rate of outdoor air supplied or temperature set-points. Some studies also included in-terventions based on the implementation of air cleaning and biophilic strategies. Both objective (e.g., physio-logical examinations) and subjective (e.g., questionnaires) measures have been used to assess the effects on office workers' outcomes. Overall, the findings presented here confirm that interventions aiming at improving IEQ in offices can be effective in improving health, well-being and productivity among office workers.

Abstract
Innovation capabilities are among the main driving sources of export performance; however, the literature on how exploration and exploitation innovation influence export performance in the context of emerging economies is scarce. As such, the purpose of this paper is to assess the relationship between innovation capabilities and export performance, mediated by exploration and exploitation innovation. For that, an online questionnaire was implemented surveying 250 Mozambican Small and Medium Enterprises (SMEs) in the agro-industry, agro-processing, and fishing sectors. Based on a Partial Least Squares Structural Equation Model (PLS-SEM) relating innovation capabilities, exploitation, and exploration innovation to export performance, it is possible to state that innovation capabilities influence the export performance of SMEs in this emerging country. Moreover, exploration and exploitation innovation exert important mediation effects, the latter being more prevalent than the former. The results constitute a major contribution as it is possible to claim that, in the context of emerging economies, Mozambican SMEs have managed to enhance their export performance, based on innovation capabilities, but, also, to master their ambidexterity with exploiting capabilities, normally linked to their current technological trajectories, being more prevalent that exploitation capabilities, which are focused on the pursuit of radical innovation. © 2022 by the authors.

Abstract
Virtual reality (VR) is used in different application fields like health, tourism, or training. Most VR applications for these fields have been built from the ground up without any authoring tool to help the process. This systematic review surveys the existing literature on authoring tools for immersive content and critically analyzes its features and how they are evaluated. It proposes a research agenda with key contribution opportunities for the field. An analysis of the 29 studies that met the eligibility criteria revealed that four records did not present any evaluation regarding the authoring tools' evaluation, and only five records used specialized users to evaluate their authoring tools; all the others used non-specialized users. The most evaluated metrics were usability, effectiveness, efficiency, and satisfaction. The data collected to evaluate the metrics consisted mainly of Likert scales and reported mean opinion score (MOS). However, few records used well-established questionnaires to evaluate those metrics like System Usability Scale, Post-Study System Usability Questionnaire, After-Scenario Questionnaire and Igroup Presence Questionnaire. Additionally, five of the analyzed records included stimuli other than audiovisual. More research is recommended about the usage of ontologies in authoring tools to comprehend the full potential of its usage since none of them had ontologies.
