Purpose: The purpose of this systematic literature review (SLR) is to analyse which consumer behaviours are more evident in relation to food waste, in addition to seeking to identify which types of food are most wasted in homes and the methods which have been used by studies for such particularities. In this paper, it was possible to identify the universe of consumer characteristics covering the main contributions to the development of this theme with different points of view. Design/methodology/approach: To achieve this goal, the authors performed a SLR according to well-established guidelines set. The authors used tools to partially support the process, which relies on a four-member research team. Findings: The authors report on 49 primary studies that deal the lack of planning, excessive purchases and the non-reuse of food leftovers by the consumer as the characteristics most evidenced as a consequence of food waste. Furthermore, fruits, vegetables and bread are the most wasted food. Regarding the most used research methods, some studies in this SLR use the qualitative method, but mostly food waste is analysed using the quantitative method. Originality/value: This SLR is different because it seeks to group different aspects of food waste, mapping not only the consumer’s behavioural characteristics but also seeking to identify the most wasted food. The research contributed to finding theoretical gaps on the subject in favour of reducing waste, based on the findings that demonstrate causing food waste.

Purpose: Business process modeling can involve multiple stakeholders, so it is natural that problems may occur during the designing and understanding processes. One way to perceive these problems is to evaluate the comprehension of business process models through the collection of data related to the readers' eye movement via an eye-tracking device. The purpose of this paper is to provide a comprehensive overview of the use of eye-trackers in understanding process models and to offer a research roadmap to challenge the community to address the identified limitations and open issues that require further investigation.Design/methodology/approach: To achieve this goal, Systematic Literature Review (SLR) was performed following good practices from the Evidence-Based Software Engineering's (EBSE) field.Findings: This study resulted in 10 primary studies selected for analysis and data extraction, from the 1,482 initially retrieved. The major findings indicate that the business process community still benefits little from the use of eye-tracking, e.g. not offering sufficient support for inexperienced designers and not having an explicit standardization in its use. These and other findings are synthesized in a research roadmap which results would benefit researchers and practitioners.Originality/value: In the studies found, the methods used to explore eyes' movement in process models' comprehension analysis were presented as an advantage of the current study. Additionally, another aspect presented in this SRL as an originality is presenting a set of open questions, suggesting valuable topics for future research through a research script (research roadmap).

User interfaces, through which users interact with the systems, should be designed according to the accessibility guidelines, with focus on usability. To this end, the designers of these interfaces should analyze whether their requirements meet the quality requirements, including their “user-friendliness” and “accessibility” features. The design of interfaces that are able to meet the needs of users with different characteristics is not a trivial task. It is paramount to involve the users and analyze how they interact with the system. Interface evaluation methods are absolutely necessary when gauging the system's quality, since they allow the identification of many usability problems where the focus in on their accessibility. The present work aims to analyze two methods of observation involving people with totally impaired vision in order to develop a protocol with recommendations that can assist professionals in the identification of characteristics and problems, which can be solved or minimized during the interfaces’ evaluations, thus facilitating the process of system access focusing on users with totally impaired vision.

Two fundamental principles and values of agile methods are customer satisfaction by rapid delivery of useful software and the improvement of the communication process by continuous stakeholders' involvement. But, how to deal with customers' satisfaction and find a better visualization model at the requirements level (which stakeholders can understand and be involved) in an agile development context? Also, how this visualization model enhancement can guarantee consistency between agile requirements artefacts (e.g., user stories and domain models)? Thus, to answer these questions, this paper presents the SnapMind framework. This framework aims to make the requirements modelling process more user-centered, through the definition of a visual requirements language, based on mind maps, model-driven and domain specific language techniques. Moreover, through these techniques, the SnapMind framework focuses on support for consistency between user stories and the domain models using a model animation technique called snapshots. The framework was applied to an industrial case study to investigate its feasibility.
