Learning environments can benefit from the enactive concept which considers human and technological aspects as coupled together so that interaction is seen as a cycle of perceptually guided actions. Although existing literature reviews have been conducted to address the use of technologies in enactive learning environments, we observe they do not address the relations of technology with core concepts of enactive systems and its social aspects. This paper presents a systematic literature review (SLR) to investigate if and how core concepts of enactive systems are being addressed by learning environments. The SLR was based on the PRISMA protocol, and considered relevant sources of studies (ACM DL, IEEE Xplore, SpringerLink, Scopus, Scielo). We based our analysis on a set of 104 selected articles (from 4514 raised), scrutinized with regards to contextual information, and a proposed set of categories of data related to subjects identified in the studies (e.g., embodiment, technology, social, among others). Our work reveals the types of technologies being used, the types of enactive interactions promoted by the technology-based environments, and the main challenges for a research agenda in the field. Our discussion raised open challenges related to a need for a common vocabulary, a framework to organize concepts in the field, and missing points that deserve further research, such as social aspects of enactive system.

Computing systems have a tremendous influence on how we understand the world. Due to its ubiquity and pervasiveness over the past decade, computing technology has created societal challenges (e.g., related to justice, sustainability, ethics, peace) that demand we reexamine how we design computer-based systems. Drawing on a phenomenological understanding of the human-technology-society relation, this work contributes to the discussion on such challenges and to design practice with a framework we call socially aware design (SAwD). We developed this framework to bring awareness to the human-technology-society relation in the design process. In this paper, we present the framework's main concepts, its underlying worldview, and its methodological base with reference to its origins. We illustrate the framework with design practices that we have experienced in designing systems in diverse situations. We also summarize key aspects of the proposed human-technology-society coupling relevant to the practice of technology design as a social phenomenon, which might open new agendas in the field.

Background and Aims: Aleurone is the innermost layer of wheat bran, rich in fiber, minerals, vitamins, phenolic compounds, and betaine. The metabolic effects of aleurone rich foods are still unknown. Our aim was to investigate the effects of consuming a Wheat Aleurone rich diet vs. a Refined Wheat diet for 8 weeks on fasting and postprandial glycemic and lipid metabolism, inflammation, and oxidative stress in overweight/obese individuals.Methods and Results: According to a randomized cross-over study design, 23 overweight/obese individuals, age 56 ± 9 years (M±SD), were assigned to two isoenergetic diet - Wheat Aleurone and Refined Wheat diets - for 8 weeks. The diets were similar for macronutrient composition but different for the aleurone content (40-50 g/day in the Wheat Aleurone diet). After each diet, fasting and postprandial plasma metabolic profile, ferulic acid metabolites and 8-isoprostane concentrations in 24-h urine samples were evaluated. Compared with the Refined Wheat Diet, the Wheat Aleurone Diet increased fasting plasma concentrations of betaine by 15% (p = 0.042) and decreased the excretion of 8-isoprostane by 33% (p = 0.035). Conversely, it did not affect the fasting and postprandial glucose, insulin and triglyceride responses, homocysteine, and C-Reactive Protein concentrations, nor excretion of phenolic metabolites.Conclusion: An 8-week Wheat Aleurone Diet improves the oxidative stress and increases plasma betaine levels in overweight/obese individuals with an increased cardiometabolic risk. However, further studies with longer duration and larger sample size are needed to evaluate the benefits of aleurone-rich foods on glucose and lipid metabolism in individuals with more severe metabolic abnormalities.Clinical Trial Registry Number: NCT02150356, (https://clinicaltrials.gov).
