Abstract
Purpose
Okara, which is the residue of hydrosoluble extract from soybean obtained after soymilk and tofu production, has high nutritional value and can be used for ingredient in specific food products. This study aims to evaluate the production and properties (physicochemical, microscopical and functional ones) of okara flour (OF) obtained from okara as a by-product of soymilk and tofu production.
Design/methodology/approach
Wet okara resulted from the soymilk process underwent convective drying up to reach mass stability (60°C for 12 h). OF properties were analyzed by official methods by AOAC, i.e. mineral composition was evaluated by atomic absorption equipment; color; water absorption index (WAI); milk absorption index (MAI); oil absorption capacity (OAC); and foam capacity (FC) required mixtures with water, milk and oil, separation and gravimetry, respectively; and microstructure was determined by a scanning electron microscope.
Findings
Results showed the potential OF has as a source of protein (24.74 g/100 g) and dietary fiber (58.27 g/100 g). Regarding its color after the drying process, OF was markedly yellow (b* parameter 20.16). Its WAI was 3.62 g/g, MAI was 4.33 g/g, OAC was 3.68 g/g and FC was 1.32 per cent. The microscopic analysis of OF showed that both loose and agglomerated particles had irregular structures and indefinite forms.
Originality/value
Production of flour from wet okara can be an alternative use of this by-product. This study showed important characteristics of OF and its possible application to the food industry. Thus, OF was shown as a potential ingredient with high nutritional value.

Abstract
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.

Abstract
Purpose
The purpose of this study is to evaluate the yield, physico-chemical and microbiological parameters during the shelf life of the Minas Frescal cheese hand-manufactured by family farms.
Design/methodology/approach
In the milk, analyses of total bacterial counts, somatic cell counts and centesimal composition were performed. The milk coagulation was analyzed, with different curd times (40, 80 and 120 min), with respect to the proximate composition, pH, titratable acidity, yield and microbiological counts. The means were compared using the Tukey test with a significance level of 5 per cent. The most probable number of microorganisms were also determined in water.
Findings
The results for milk quality were within the requirements established in Normative Instruction 62, except for total dry extract. It was found that curd time did not influence the protein and fat in dry matter contents; however, the ash content in cheese of 40 min of curd time (2.8 g/100g) is significantly higher (p = 0.02) than the values found for the other curd times. The same behavior was observed for moisture content (p = 0.04). The parameters determining the cheese quality were outside the standards for human consumption, but this result is directly related to the water conditions, which were outside of potability levels. To meet the requirements established in the legislation, dairy products must follow strict standards of quality hygiene, both the raw material (water, milk) and their employees who act directly in the process.
Originality/value
For the preparation of the Minas Frescal cheese, it takes several steps, from obtaining the milk to the product ready to be consumed, so the importance of doing this monitoring and evaluating its quality.

The purpose of this study is to explain how online brand communities work to support the denormalization of controversial (i.e. illegal yet normalized) gaming practices.
Abstract
Purpose
The purpose of this study is to explain how online brand communities work to support the denormalization of controversial (i.e. illegal yet normalized) gaming practices.
Design/methodology/approach
This qualitative study was characterized by long-term immersion in an online brand community for Brazilian Xbox gamers. The dataset includes online and offline interactions with community members, interviews, and online archival data.
Findings
This study shows how online brand community members promoted legal gaming in a market where piracy was prevalent. It demonstrates how community members worked to establish coherence; engaged in cognitive participation; developed collective action that extended beyond the community; and reflected on their own work.
Research limitations/implications
This study identifies online brand communities as a potential ally in combating controversial practices in online gaming; complements individual and behavioral approaches in explaining why consumers adopt controversial practices in online environments; and adds a normalization framework to the toolkit of Internet researchers.
Practical implications
This study identifies ways in which the potential of online brand communities can be leveraged to reduce consumer adherence to controversial gaming practices through denormalizing these and normalizing alternative practices that may be more desirable to companies and other stakeholders.
Originality/value
This long-term, qualitative study inspired by normalization process theory offers an innovative perspective on the online practices of consumers who engage with a brand in ways that create value for themselves and for the brand.

Abstract
Purpose
The purpose of this paper is to analyse how Lean office planning and implementation take place in a Brazilian regulatory agency and to investigate the adjustments needed for its implementation.
Design/methodology/approach
A longitudinal case study was conducted. Interview was the main source of evidence. Between September and October 2012, data about the planning phase were collected; between April and May 2015, Lean office implementation was investigated. Altogether, five employees of the agency were interviewed.
Findings
The agency assumed its mission as value for the user, establishing control process, evaluating and improving processes to achieve perfection and recognising its weakness in a continuous improvement culture. Planning and implementation of Lean office in the regulatory agency followed the main recommendations in the literature. However, adjustments were necessary in accordance with the particularities of the public institution.
Research limitations/implications
Owing to the nature of this study, no generalisation was possible. Moreover, interviews with managers were about both Lean planning, which has taken place in the past, and Lean implementing, which is still running; thus, some information may be abstruse.
Practical implications
It was possible to list the main adjustments needed for planning and implementing the Lean office in the public agency and some are applicable for other public administration bodies.
Originality/value
Lean office studies are mainly related to private organizations, but this paper demonstrates that their fundamentals are preserved in public service, and thus it proved that Lean thinking may be applied to the public administration. It also raised a series of questions for future studies.

Abstract
Purpose
The purpose of this research is to relate the characteristics transferred from teaching into simulation-based learning in nursing by highlighting how they are presented and, thus, focus on more assertive pedagogical actions in higher education.
Design/methodology/approach
The research was performed in the Brazilian context through a survey, and the data were analyzed by the structural equation modeling.
Findings
The results show meaningful relationships for the four factors that are impacted by simulation-based learning: clinical reasoning for decision-making, patient safety, self-confidence and knowledge.
Practical implications
This research identified the importance of simulation as an alternative to improving the teaching–learning process, and it can contribute to structuring the nursing program curriculum and other training zones, by enabling the inclusion of new methodological modalities.
Originality/value
The simulation strategy becomes a differential tool in the integration between theory and practice, especially in the nursing program, and promotes teamwork, leadership and communication, self-confidence, critical thinking, clinical reasoning, priority management, decision-taking and conflict management.

Abstract
Purpose
The purpose of this paper is to evaluate the efficiency of a duckweed pond in the polishing of a stabilization pond effluent, as well as quantify its biomass production. Once an adequate destination is given to the produced biomass, the wastewater treatment plant can work in a sustainable and integrated way.
Design/methodology/approach
The duckweed pond consisted of a tank with volume 0.44 m3, operating in continuous flow with an outflow of 0.12 m3/day and hydraulic retention time of 3.8 days. Effluent samples were collected before and after the treatment, with analyzes made: daily-pH, dissolved oxygen and temperature; twice a week – total nitrogen (TN), total phosphorus (TP) and chemical oxygen demand (COD); and weekly – total solids (TS) and Biochemical Oxygen Demand (BOD5). The duckweeds were collected each for seven days for its production quantification.
Findings
The highest efficiency of TN, TP, COD, BOD5 and TS removal were of 74.67, 66.18, 88.12, 91.14 and 48.9 percent, respectively. The highest biomass production rate was 10.33 g/m2/day in dry mass.
Research limitations/implications
There was great variation in biomass production, which may be related to the stabilization pond effluent conditions. The evaluation of the effluent composition, which will be treated with duckweeds, is recommended.
Practical implications
The evaluated treatment system obtained positive results for the reduction in the analyzed variables concentration, being an efficient technology and with operational simplicity for the domestic effluent polishing.
Originality/value
The motivation of this work was to bring a simple system of treatment and to give value to a domestic wastewater treatment system in a way that, at the same time the effluent polluter level is reduced and it is also possible to produce biomass during the treatment process.
