PurposeThe 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/approachTo 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.FindingsThe 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/valueThis 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.

Information Technology (IT) governance in small and medium-sized businesses is a subject that still requires more effort. Many of the studies that deal with this subject refer to large companies. IT governance structures, originally developed for the context of large enterprises such as COBIT, ISO/IEC 35800 or ITIL, when applied to the context of small and medium enterprises, lead to undesirable results and failures in the deployment process. The objective of this work was to perform a systematic mapping on IT governance in small and medium enterprises between 2007 and 2017. Systematic mapping studies are useful for categorizing and summarizing the existing information concerning a research question in an unbiased manner. Thus, from an initial set of 63 papers, a total of 17 research papers were selected for the mapping study. The results obtained allowed us to reach conclusions concerning the state-of-the-art of IT governance mechanisms, theories applied in the context and the consequences of IT governance. From the results of this study it was possible to perceive the low use of relational mechanisms of IT governance in the studied context, the constant need to adapt frameworks such as COBIT and ITIL, so that they can adapt to the reality of SMEs, the wide variety of theoretical approaches and the importance, for SMEs, of the concept of IT value for the business.
