Labs are meant for the creation of new products and services or to overcome innovation challenges (Carstensen & Bason, 2012). Media labs, besides the name, go beyond the media industry concepts to respond to technology, communication, and economic changes (Bisso Nunes & Mills, 2021). For that, they integrate public spaces, media, arts, and tech. In short, media labs are organizational structures that allow for experimentation and development, and facilitate open innovation and individual and organizational learning. Many media labs are focused on accelerating media involvement in functional and experimental innovations and rise in a context unrelated to the temporality of media content production, on a systematic innovation approach. But media labs also represent great diversity. In this chapter, we explore key elements of the media lab phenomenon: history, definition, evolution and appearance globally and in Latin America, emergence beyond the media industry, and, by the end, final thoughts about media labs' roles amid future organizational and technological transformations.

We present a critical literature review debating Brazilian research on social and environmental accounting (SEA). The aim of this study is to understand the role of politics in the construction of hegemonies in SEA research in Brazil. In particular, we examine the role of hegemony in relation to the co-option of SEA literature and sustainability in the Brazilian context by the logic of development for economic growth in emerging economies. The methodological approach adopts a post-structural perspective that reflects Laclau and Mouffe’s discourse theory. The study employs a hermeneutical, rhetorical approach to understand and classify 352 Brazilian research articles on SEA. We employ Brown and Fraser’s (2006) categorizations of SEA literature to help in our analysis: the business case, the stakeholder–accountability approach, and the critical case. We argue that the business case is prominent in Brazilian studies. Second-stage analysis suggests that the major themes under discussion include measurement, consulting, and descriptive approach. We argue that these themes illustrate the degree of influence of the hegemonic politics relevant to emerging economics, as these themes predominantly concern economic growth and a capitalist context. This paper discusses trends and practices in the Brazilian literature on SEA and argues that the focus means that SEA avoids critical debates of the role of capitalist logics in an emerging economy concerning sustainability. We urge the Brazilian academy to understand the implications of its reifying agenda and engage, counter-hegemonically, in a social and political agenda beyond the hegemonic support of a particular set of capitalist interests.

The native species from western Mato Grosso do Sul provide fruits with unique sensory characteristics and high nutrient concentrations. Tropical fruit consumption is increasing due to the growing recognition of the nutritional value. These fruits play important roles through the marketing of their products and nutritionally through their consumption. All fruits are edible and are used in the food industry and well sensory accepted. The purpose of this paper is to verify the physicochemical characteristics, bioactive compounds and antioxidant activity in fruits collected in the Cerrado and Pantanal biomes from western Mato Grosso do Sul.

The fruits of baru, bocaiuva, jatobá, jenipapo and pequi were collected. To characterize them, longitudinal diameter, transverse diameter, total soluble solids, acidity, pH, ascorbic acid, total phenolics, antioxidant capacity, total sugar, glucose and macro and micronutrient contents analysis were performed in triplicate.

Jatobá presented the highest values of vitamin C. For phenolics, baru and jatobá stood out; bocaiuva presented the highest results for sugars, while jatobá was superior for glucose. The fruits with the highest antioxidant capacity, DPPH, were pequi and baru, while via ABTS the jatobá was the highest. Baru presented higher levels of nitrogen, phosphorus, magnesium, copper, zinc and iron. The bocaiuva presented the highest results for potassium and sulfur, the jatobá calcium and manganese. Jenipapo stood out with its boron content. Magnesium presented superior results in the baru, jenipapo and bocaiuva. The results reinforce the diversity of physicochemical characteristics.

The increase of the flow of available information, together with the growth of multicultural influences, the search for wholesome diet and the diversity of flavors and colors make these fruits important regional development tools. Their characteristics encompass national and international exploration potential that arouse consumer interest and contribute to the pursuit of innovations. In addition, the native species mentioned above provide fruits with unique sensory characteristics. Their consumption is increasing in the markets due to the growing recognition of their nutritional value. Therefore, these fruits play important roles, economically, through the marketing of their products and nutritionally through their consumption.

The purpose of this paper is to evaluate the effect of the bodying agents (erythritol, sorbitol, xylitol and polydextrose) and their mixtures on the preparation of mixed Brazilian Cerrado fruit preserves (marolo, soursop and sweet passion fruit).

The simplex mixture design was used for product optimization and the preserves evaluated by physical, physicochemical and sensory properties. The research data were analyzed using regression equations on SAS University and exploratory analysis by principal component analysis and parallel factors techniques on Sensomaker software.

The results show that erythritol and polydextrose bodying agents should not be used as pure components because they provoked changes in the properties of the final product and negatively influenced the sensory attributes. While the high concentrations of xylitol and sorbitol provided better sensorial acceptance, being considered, therefore, good substitutes for sucrose.

This research has shown it is feasible to use bodying agents in the preparation of mixed Brazilian Cerrado fruit preserves without added sugar.

The development of mixed preserves could increase population access to the Brazilian Cerrado fruits. In addition, sugar-free preserves are a viable alternative for adding value to the product and satisfy all the consumers.

The combination of properties of two or more fruits and use of bodying agents can improve sensory, physical and physicochemical characteristics of the final product. However, there are technological challenges to evaluate in the preparation of mixed Brazilian Cerrado fruit preserves without added sugar.

The purpose of this paper is to discuss integrative environmental assessments applicable to estuarine sediments, including the advantages and limitations of different lines of evidence that could form part of such assessments and their application to ecosystem services.

Weight of evident framework integrating multiple lines of evidence for sediment quality assessment.

Integrative environmental assessments are required to fully address the risks to resident fauna of anthropogenic contaminants deposited in estuarine sediments.

The paper presents an updated discussion of the methodologies for environmental assessments of contaminated estuarine sediments.
