Abstract
Purpose
The purpose of this paper is to propose a set of lifecycle-based indicators to describe material eco-efficiency of buildings normalized per unit of gross floor area (GFA), and at verifying feasibility of their calculation for building materials and components, based upon four case studies. The paper also examines the effects that discrepancies between two carbon footprint accounting methods (embodied CO2 (ECO2) vs embodied CO2e) have on communication of environmental performance of selected materials.
Design/methodology/approach
The lifecycle assessments (LCAs) were performed through LCA support platform SimaPro 7.3. Data for materials/components production cycle modeling were collected from primary and secondary data from national literature or adapted from Ecoinvent database. Embodied energy, ECO2, blue water footprint (bWF), non-renewable content and volatile organic compound emissions (VOCe) indicators were calculated from lifecycle inventory (LCI) outputs, while embodied CO2e was calculated using CML 2001 v.2.01 impact assessment method.
Findings
Obtained results suggest that a core database comprised of 12 materials and components – cement, ceramic blocks, steel rebar, sawn timber planks, PVC tubes, plywood, PVC conduits, roof steel structure, roundwood, ceramic tiles, hydrated lime and adhesive mortar – provides a very reasonable description of a building's embodied energy (99.63 percent), embodied CO2e (97.50 percent), bWF (96.26 percent), non-renewable content (97.53 percent) and VOCe (95.38 percent) profiles. Except for bWF of cement and concrete, substantial reductions in the metrics’ values captured environmental advantages of partially substituting ground granulated blast furnace slag (ggbs) for clinker Portland.
Originality/value
The disclosure of embodied energy and carbon, as well as of other environmental performance data at whole-building level (per unit of GFA) pointed out in this paper, allows comparability and helps to establish performance goals and benchmarks and to guide policy decisions. Following a coordinated methodological outline, future works are expected to evolve to gradually constitute a LCI database that enables the use of the proposed metrics and of LCA as decision-making tools in the building sector.

Abstract
Purpose
Higher education institutions are widely known both for their promotion to education for sustainable development (ESD) and for their contribution as living labs to urban management strategies. As for strategies, smart and learning campuses have recently gained significant attention. This paper aims to report an air quality monitoring experience with focus on the smart and learning campus and discuss its implications for the university context with regard to ESD and sustainable development goal (SDG) integration.
Design/methodology/approach
The air quality monitoring was held at the main campus of University of Passo Fundo and focused on three pollutants directly related to vehicle emissions. The air quality index (AQI) was presented on a website, along with information regarding health problems caused by air pollution, main sources of emissions and strategies to reduce it.
Findings
The results showed how the decrease in air quality is related to the traffic emissions and the fact that exposing students to a smart and learning environment could teach them about sustainability education.
Practical implications
This case study demonstrated how monitoring air quality in a smart environment could highlight and communicate the impact of urban mobility on air quality and alerted to the need for more sustainable choices, including transports.
Originality/value
This paper contributes to the literature by showing the potential of a smart-learning campus integration and its contribution towards the ESD and the UN SDGs.

Abstract
Purpose
In laminate composite structure design, it is common to deal with the need of varying thickness to reach project requirement or improve performance. This change of thickness can be achieved by terminating or adding plies at different locations over the laminate. Unfortunately, the inherent weakness of this construction is the presence of material and geometric discontinuities at the ply drop region that induce premature interlaminar failure at interfaces between dropped and continuous plies.
Design/methodology/approach
In this work, tensile strength tests were performed on tapered laminates with internal ply drop-off using digital image correlation (DIC) technique. The laminate based on a new thermoplastic ELIUM® 150 reinforced by a plain weave carbon fabric was manufactured via VARTM. Stress, strain, displacement and tensile strength were analyzed. A 3D finite element analysis (FEA) and design of experiments (DOEs) were carried out for the analysis of effect of position and angle orientation of dropped plies near the thinner section of the tapered laminate. Tsai Wu's criterion was implemented to predict initiation of first ply failure.
Findings
Numerical and experimental results showed that position and angle orientation of ply drop-off near the thinner thickness influence tensile strength of tapered laminate. Tensile static strength increases 12% when drop-off near the midplane is oriented at ±45° instead of 0°. Results showed a trend of improvement in the tensile strength when drop-off is positioned over midplane of the laminate composite. Results obtained through the DOEs were able to adjust the metamodel according to a linear model with great efficiency. They show the significant relevance of the manufacturing variables and the interaction between the factors.
Originality/value
The present work aims to evaluate the effect of ply drop-off on the strength of carbon fiber thermoplastic composite laminates with internal drop-off under tensile load and propose a design guideline about angle orientation and position of dropped plies closer to the thinner section of the laminate.

Abstract
To claim for communication professionals the ethical responsibility of contributing to the public debate within the realm of their function in scientific and technological organizations, giving people the power to analyze the information available to them and based on that make better-informed decisions on issues that affect their lives, is the sole purpose of this exercise. Departing from a focus on the messages – information, misinformation and disinformation – we defend to refocus on relations to enable people to make the distinction between them, and then fulfilling communication’s purpose of reflexion.
Through a review of literature, we set out to delimitate and contextualize the role of communication professionals in scientific and technological organizations in today’s social and political environments. We conclude that communication professionals in scientific and technological organizations do need to embrace the responsibility to contribute to the empowerment of citizens regarding their access to information and ability to navigate through the overwhelming amount of data they have access to daily.
As we witness the rise and expansion of populist movements throughout the globe, it is not of lesser importance to reflect on the role of scientific and technological organizations in the public debate. As it is here that public opinion forms, it is important that organizations involved in the scientific and technology development call on themselves and embrace it as part of their identity, the responsibility to inform the decision-making process of citizens with the purpose of bettering it.

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 use of film language in management is an interesting method to understand the concept of leadership in the internal and external contexts of organizations, by means of metaphors. Thus, the objective of this study was to analyze the metaphors of leadership in a movie.
Design/methodology/approach
This was a qualitative research, which used the strategy of film analysis and content analysis (Bardin, 2016). Data were collected by scene decoupage, registered in an observation protocol. In the field of management, there is a growing interest in film analysis for understanding organizations, from inside and outside, by using dynamic methodologies.
Findings
The use of metaphors in film analysis made it possible to interpret concepts, for a better understanding of organizations. The identified leaders, despite adopting different attitudes at work, reach a common goal, with gains for the community.
Originality/value
This article also contributes to reflect on the teaching–learning process of management research through different methodological dimensions.
O uso da linguagem fílmica na administração se apresenta como um método interessante para entender o conceito de liderança nos contextos interno e externo das organizações, por meio das metáforas. Assim, o objetivo deste estudo foi analisar as metáforas de liderança existentes em um filme. Trata-se de uma pesquisa qualitativa, com uso da estratégia de análise fílmica e análise de conteúdo (Bardin, 2006). Os dados foram coletados por meio da decupagem das cenas, registradas em protocolo de observação. No campo da administração, percebe-se que existe um crescente interesse na análise fílmica para compreender as organizações, de maneira interna e externa, com metodologias dinâmicas. O uso de metáforas na análise do filme possibilitou interpretar conceitos para melhor compreender as organizações. As lideranças identificadas, apesar de adotarem posturas diferentes no processo de trabalho, chegam a um objetivo comum, com ganhos para a coletividade. Esse artigo também contribui para pensar em processo de ensino-aprendizagem da pesquisa na administração em diferentes dimensões metodológicas.

The purpose of this paper is to optimize a mixed juice made from Brazilian Cerrado fruits (cagaita, mangaba and marolo).
Abstract
Purpose
The purpose of this paper is to optimize a mixed juice made from Brazilian Cerrado fruits (cagaita, mangaba and marolo).
Design/methodology/approach
The juices were evaluated by rheological, physical, physicochemical, nutritional and sensory acceptance analyses. The mixture design is a widely used tool for product optimization, allowing the determination of factors, combinations and levels that provide best responses.
Findings
The results show that using mangaba pulp negatively contributed to juice acceptance, but resulted in the highest ascorbic acid content. The treatments produced using cagaita and marolo pulps presented a greater acceptance by consumers, and contributed to higher antioxidant activity and phenolic compounds content. The juice prepared with a mixture of equivalent quantities of the three fruits had the highest β-carotene and lycopene contents.
Practical implications
This research has shown that different fruit combinations can improve sensory and nutritional characteristics, adding value to the final product.
Social implications
The processing of mixed juices could increase population access to the nutrients present in Brazilian Cerrado fruits, given that they are seasonal and perishable fruits.
Originality/value
In recent years, there has been an increase in the development of new food products based on Cerrado native fruits, however information on the chemical and nutritional characteristics, rheological behavior, and sensory attributes of the derivative products are still limited, resulting in a lack of scientific investments in this area. In addition, it is necessary to optimize the developed products to offer the consumer a unique product, combining the characteristics of two or more fruits, which adds value to the final product.

Abstract
Purpose
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).
Design/methodology/approach
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.
Findings
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.
Practical implications
This research has shown it is feasible to use bodying agents in the preparation of mixed Brazilian Cerrado fruit preserves without added sugar.
Social implications
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.
Originality/value
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.

Abstract
Purpose
This paper aims to show which factors influence the perception of human resources professionals about managers over 50 years old and which factors guide the age management practices adopted in the surveyed companies.
Design/methodology/approach
To this end, a survey was conducted with 140 companies accessed from a database of a human resources association. Through the answers obtained through the online questionnaire, an exploratory factor analysis was made with the aid of Software R.
Findings
Thus, it was possible to identify four factors that explain the work posture of professionals 50 years of age and older (company expectations, performance, morality and knowledge and professionalism) and three factors that guide the adoption of age management practices in organizations (recruitment & selection and integration, retention and continuity in the company, adaptation to the needs).
Originality/value
The results suggest that, even considering the high performance of older managers, perceived by HR professionals, the adoption of age management practices is still insufficient, making it difficult for these professionals to enter and remain in organizations. Moreover, it can be inferred that such posture indicates biases of discrimination and age stereotypes.

This study aims to propose a framework for constructing a sustainable higher education institution (HEI) from the perspective of transformative learning.
Abstract
Purpose
This study aims to propose a framework for constructing a sustainable higher education institution (HEI) from the perspective of transformative learning.
Design/methodology/approach
This literature review focused on the construction framework, using themes of transformative learning approach and learning cycles and transitions approach.
Findings
This study reviews the articulation between the levels of transformative learning (instrumental, conventional, green and sustainable HEIs) and learning cycles (single-loop, double-loop and deutero-learning). The study explores how the maturity of HEI, process until it achieves higher levels of sustainability. However, positioning a HEI on a macroscale level is utopian as it represents an ideal type, using Max Weber’s terminology, which can only be overcome through deep institutional changes driven by sustainable concerns.
Research limitations/implications
The limitations of the framework, links to the limited number of studies that applied the I3E model – acronym for inform, engage, empower and embed – (Cebrián, 2016) and the lack of deepening of the four elements proposed to understand the process of sustainable management. The article expands on the literature by proposing ways for HEIs to engage toward a paradigm shift and a critical-based sustainable transformation.
Practical implications
This article provides an integrated approach for incorporating sustainable practice concerns into education, management, research and university–society relations. In addition, the results provide policymakers in HEIs with an understanding that transformative learning guides protocols to address challenging sustainability issues, in addition to new perspectives, approaches and understandings that bring the maturity levels of HEIs closer to an ideal sustainability model.
Originality/value
The study opens space for new research to be conducted, investigating how progress occurs in the face of sustainability and how it can be improved, in addition to serving for HEIs as a guide to actually becoming spaces where there is greater awareness, social justice, ethics and critical thinking. By using the transition to sustainability approach, it is possible to view how HEIs move toward a transition, understanding how it is managed and can be improved.
