Abstract
Purpose
Despite the continuous development of Building Information Modeling (BIM) standards, not all of its dimensions are supported to the same extent. This is the case of Building Automation Systems (BAS) in which the features that are limited mostly to physical setup of devices are supported. These are largely insufficient to support modeling automation scenarios. The purpose of this article is to clarify the gap in the state of the art and define the need for further developments.
Design/methodology/approach
This article explores the existing gap in the literature and discusses the hypothesis of extending BIM to a wider support of BA concepts. Based on an assessment of scientific and technical literature, this study elicits the information requirements of BA and performs a gap analysis with current BIM standards, such as Industry Foundation Classes (IFC).
Findings
Our findings lead us to conclude that there is a lack of completeness regarding features from BAS automation and management levels. Furthermore, it is shown that IFC is the most adequate data model to cover BAS without losing its purpose, but there is still a considerable work that needs to be addressed in future research.
Originality/value
BIM standards such as IFC position themselves as natural candidates for modeling and exchanging information regarding BA. However, the extent to which BIM supports automation features has never been rigorously analyzed. This article explores the existing gap in the literature and discusses the hypothesis of extending BIM to a wider support of BA concepts. Based on an assessment of scientific and technical literature, this study elicits the information requirements of BA and performs a gap analysis with current BIM standards such as IFC.

Abstract
This chapter examines books written by foreign authors which were published in Brazil and censored by the military regime between 1964 and 1985. The study focuses on non-fiction books, using official period documentation, with the goal of conducting an extensive survey of these works as well as examining the reasons why they were censored by the regime. The results of the research lead us to a greater understanding of the reasoning of censorship from within the State and to a greater understanding of the Brazilian military dictatorship as a whole.

Abstract
Examines the tenth published year of the ITCRR. Runs the whole gamut of textile innovation, research and testing, some of which investigates hitherto untouched aspects. Subjects discussed include cotton fabric processing, asbestos substitutes, textile adjuncts to cardiovascular surgery, wet textile processes, hand evaluation, nanotechnology, thermoplastic composites, robotic ironing, protective clothing (agricultural and industrial), ecological aspects of fibre properties – to name but a few! There would appear to be no limit to the future potential for textile applications.

Abstract
Purpose
This study aims to analyze which collective actions (cooperation, coordination and collaboration), present in the supply chain of artisanal products, generate positive effects in terms of social gains.
Design/methodology/approach
The authors conduct multiple case studies in the supply chain of seven artisanal agroindustries in the Distrito Federal, Brazil. The data were collected through interviews, documental analysis and direct observation. The data were analyzed using the content analysis technique proposed by Bardin (1977). With priori and a posteriori analytical categories, it was possible to conduct: a detailed analysis of the current situation of artisanal agroindustries regarding collective actions from the perspective of supplier/supplier and supplier/client and a detailed analysis for the possible effects of collective actions that impact the supply chain and the indicators of social sustainability of artisanal agroindustries.
Findings
The results indicate that cooperation and collaboration have contributed positively in the transactions of the products of the artisanal agroindustries, reflecting in social gains for the producing families. In this context, some collective actions can be highlighted as follows: the collective commercial spaces, the demonstration spaces of the artisan products in the clients’ environment, the prospecting of improvements from the final consumers, the face-to-face meetings with the suppliers, the product dissemination by the customer, the joint marketing actions and the rationalization of transportation logistics.
Research limitations/implications
The study used a qualitative approach and findings and discussion are inherently interpretative and cannot be generalized.
Practical implications
This study can contribute to researchers and practitioners interested in collective actions contributing to the incrementation of social responsibility in agri-food supply chains.
Social implications
Understanding how the collective actions support the inclusion of smallholding and artisanal producers in agri-food supply chains can help policymakers and managers to implement initiatives related to social responsibility, which can be measured using social indicators. This creates a social benefit through rural growth and economic development, generation of income and social productive inclusion of the artisanal producers in larger agri-food supply chains.
Originality/value
For the best of the authors’ knowledge, this is the first paper approaching collective actions as the main source of incrementation of social benefits, which can measure the incrementation of social responsibility in agri-food supply chains.

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
This study addresses how and when the experience of family-induced work strain might steer employees away from efforts to promote innovative ideas. In particular, it proposes a mediating role of role ambiguity and moderating roles of two coworker resources (goal congruence and goodwill trust) in this process.
Design/methodology/approach
The research hypotheses are tested with data obtained from a survey administered among employees who work in a professional services organization.
Findings
An important explanatory mechanism that links family interference with work to diminished championing efforts is that employees hold beliefs that their job roles are unclear. The extent to which employees share work-related mindsets with coworkers, as well as their belief that coworkers are trustworthy, attenuate this harmful effect.
Practical implications
For HR managers, the study shows a clear danger that threatens employees who feel drained by significant family demands: The negative situation may escalate into work-related complacency (diminished championing), which then may generate even more hardships. As it also reveals though, employees can leverage high-quality coworker relationships to contain this danger.
Originality/value
This study adds to HR management research by investigating the role of negative spillovers from family to work in predicting idea championing, as explained by negative beliefs about job-related information deficiencies but buffered by high-quality coworker relationships.

Abstract
Purpose
To describe water absorption by the rice grains over time, diffusion and empirical models were used. Also, an optimization software was developed in this study to determine parameters and their uncertainties for the diffusion models (LS Optimizer, for partial differential equations). Parameters (and their uncertainties) for empirical models were determined by LAB Fit Curve Fitting Software.
Design/methodology/approach
Heat and mass diffusion phenomena are found in various processes of technological interest, including pasteurization, drying and water immersion of agricultural products, among others. The objective of this work was to study the process of water absorption by rice grains with and without husk, using diffusion and empirical models to describe the absorption kinetics. Rice grains were immersed (approximately 10 g for each experiment) in drinking water maintained at constant temperatures of 28, 40 and 50 C. In the experiments, the water contents absorbed by rice grains over time were obtained by the gravimetric method.
Findings
Among empirical models, Peleg was the most satisfactory to describe the kinetics of water absorption by rice without husk, while the Silva et alii model had the best statistical indicators for rice with husk. It was also verified that a diffusion model with boundary condition of the first kind showed the best (or equivalent) results in the description of all processes of kinetics of water absorption by rice grains, with and without husk. For grains without husk, the effective mass diffusivities were (1.186 ± 0.045) × 10−9, (1.312 ± 0.024) × 10−9 and (2.133 ± 0.028) × 10−9 m2 min−1, for the immersion temperatures of 28, 40 and 50C, respectively. For grains with husk, diffusivities were (0.675 ± 0.011) × 10−9 and (1.269 ± 0.017) × 10−9 m2 min−1, for temperatures of 28 and 50 C, respectively.
Originality/value
This work developed a solver for the diffusion equation in cylindrical geometry and presented the LS Optimizer software developed to determine differential equation parameters through experimental data sets.

Abstract
Cangaço was a form of banditry that occurred in the North-East of Brazil between 1870 and 1940. The movement has inspired many films over the years. This chapter explores the contribution of Cangaço-inspired productions to Brazilian cinema, as well as the particular characteristics of what constitutes the Cangaço genre.
Following a historical survey of the Cangaço, the films were divided into different categories and ranked in terms of relevance. Only the most important are discussed in this chapter.
The Cangaço has been portrayed in Brazilian cinema through the decades in diverse ways, dating back to the 1920s. After becoming a consolidated film genre in the 1950s, then known as Nordestern, the Cangaço finally acquired a proper structure, featuring multiple Western references among its common characteristics. In the 1960s, Glauber Rocha, one of the most prominent filmmakers of the Cinema Novo avant-garde movement, added his own symbolism to the genre. Eventually, the Cangaço was also revisited by directors who combined it with other genres such as comedy, documentary, and erotic films. Another relevant reinterpretation came in the 1990s, when filmmakers of the so-called New Brazilian Cinema offered a new view on the subject.
Despite its strong association with Brazil, the Cangaço has not been thoroughly investigated by researchers. This chapter presents a historical survey and analysis of Cangaço films, highlighting their relevance to Brazilian cinema.

Abstract
Purpose
The purpose of this paper is to analyze how, in three different contexts, the National Council for Advertising Self-Regulation narratively uses its past to build an official history concerning its origins that legitimates advertising self-control as a hegemonic narrative.
Design/methodology/approach
By using the historical research and the “uses of the past” approach, this study identifies, analyzes and confronts three organizational histories of Conar’s origins (both its official and unofficial versions) in the context of the creation of the Brazilian system of advertising self-regulation.
Findings
After a thematic analysis of the documentary sources, the narratives on the National Council for Advertising Self-Regulation’s origins and the self-control process were grouped into three versions: the narrative under the military regime: 1976/1980; the narrative during the process of re-democratization of the country: 1981/1991 and the contemporary narrative: from 2005 onwards. These narratives were confronted and, in consequence, provided, each of them, a different interpretation of the context surrounding the creation and justification for advertising self-control.
Originality/value
The study shows how a consumer defense organization re-historicized its past strategically to gain legitimacy in three different ways through time. It also reveals that organizations strategically use their past to build an intended vision of the future, thus having more agency than the hegemonic literature in management studies usually guarantees. Finally, it exposes the malleability of past narratives through which organizations play a critical role in the ongoing struggle for competing uses of the past. Therefore, the study identifies different organizational stories through time that allow researchers to reflect on several strategic uses of the past by organizations.
