Drawing on the conservation of resources (COR) theory, this study aims to assess the moderating effect of the psychological contract (PC) type (relational, transactional and balanced) on the relationship between psychological contract breach (PCB) and organizational citizenship behaviours (OCBs).

The authors administered a survey to a sample of 159 nurses working in a large public hospital. To analyse the survey data, the authors used partial least squares with SmartPLS v.3.3, a variance-based structural equation modelling technique that combines principal component analysis, path analysis and regression analysis.

This study shows that nurses counteract the loss of resources following a PCB by investing more in stronger interpersonal relationships with co-workers and patients as a way to recuperate from resource loss and gain social resources. In addition, the moderating effect of the PC type reinforces the relationship between a PCB and OCB in a way that relational and balanced PC types support OCB-I positively but negatively OCB-O. Furthermore, the transactional PC does not reinforce negatively the link between PCB and OCB-I, and the negative interacting effect on the PCB and OCB-O link is only partially supported.

The study findings are grounded on a cross-sectional research design and a convenience sampling strategy.

The results highlight the relevance of human resources management practices centred on employee involvement and participatory supervision styles for ensuring OCB display at the workplace.

The results add new evidence to COR theory by highlighting the importance of social resources as a mitigator in the relationship between nurses’ PCB and OCB towards co-workers and patients (OCB-I). Hence, the OCB-I display will vary in function of the target and the moderating effect of PC type (relational, balanced or transactional).

This paper investigates how chain members collaborate to ensure the sustainability of supply chains through the social capital perspective.

Following a case study design, three social capital mechanisms – reach, richness and receptivity – were used as a lens with two eco-innovative food companies and their respective supply chains in Southern Brazil. Data consisted of interviews and other sources of evidence obtained from multiple stakeholders.

Results highlight the importance of a managerial orientation for sustainability and that sustainable chains presuppose a network that is closely linked and with great affinity. Not only does the management of operations improve the green performance of companies for environmental benchmarking but it also expands to include the supply chain. Social capital mechanisms can encourage partners to develop strategic initiatives for sustainability, especially if managers share key drivers for adopting eco-innovations and overall chain sustainability.

The paper contributes to research on collaboration within sustainable supply chain management. Empirical data were gathered from different stakeholders in two food chains in a developing country. Through the lens of social capital mechanisms, the paper shows how different types of companies collaborate in their supply chain for sustainability.

The purpose of this paper is to analyse how internal and external factors can influence on the adoption of eco-innovation by food companies. Although innovation and sustainability are relevant concepts, they are not being considered together in the literature. Hereof, eco-innovation encloses both approaches.

A survey with 581 Brazilian companies was conducted. The structure of influential internal and external factors was analysed by an exploratory factor analysis, and the relations between groups of variables identified in the study were verified through regression analysis. Environmental capability, environmental managerial concern and human resources were internal factors investigated in this study, and regulatory and normative pressures, cooperation and government support were the external factors.

Human resources was the most important internal factor, followed by environmental managerial concern and environmental capability. Collaboration was the most important external factor, followed by normative pressures and environmental regulations, while government support was seen as deficient. Companies stated that these factors were important to adopt environmental practices and increase performance.

Understanding why food companies adopt eco-innovation will help policy makers to develop specific actions to promote eco-innovations. For managers, it can be a relevant tool to identify which factors to invest, if the company is eco-strategizing. Hiring committed staff, top management green consciousness and collaboration with key stakeholders can boost sustainability.

This study brings an innovative approach with robust theoretical support in a comprehensive conceptual model, gathering and investigating all relevant internal and external factors in the literature. Those factors are used in an integrated way in the final model for the empirical investigation, while the literature generally emphasizes only external factors.

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.

Several studies focus on agri-food value chain from a consumer or from a supply chain perspective. But there is little investigation integrating both approaches and providing empirical evidence from developing countries. The purpose of this paper is twofold: first, it describes the supply chain of organic products in Brazil, which is an emerging market. It describes how retailers manage its supply chain (wholesalers and small producers) in an organic own brand of fresh products. Second, this paper identifies the motivations, attitudes, beliefs and personal values behind Brazilian consumers' decision to purchase organic food.

Qualitative and quantitative techniques were used in two stages. First, it presents a case study of the organic supply chain. Then, a survey carried out with 261 consumers at supermarkets in a Brazilian city is presented.

The case study points out that retailers transfer to wholesalers the responsibility to manage small organic producers. It also suggests that as the organic product is under the retailer own brand, and therefore most of the value perceived by the consumer is retained by the retailer. Survey results indicate that organic consumers have strong individual values and benefits are the most significant predictors of attitude toward organic food for the Brazilian consumers interviewed. Availability is significantly related to the intent to purchase organic food, which is a key point for the supply chain to respond efficiently to consumers' demand.

This paper is based on a single case study and the survey is applied in only one city of Brazil.

The study contributes to expand the value analysis through a combination of quantitative and qualitative techniques, including consumer behaviour and supply chain management in the same analysis. It also adds to the debate on value, proposing Schwartz Value Theory as a complementary approach to value analysis.

The purpose of this study is to examine the influence of characteristics of the institutional environment on the disclosure of corporate social responsibility (CSR).

This is a quantitative and descriptive research. The dependent variables used were environmental dimension (ED) and social dimension (SD) that together compose the corporate social performance (CSP). The independent variables that will be used are the characteristics of the institutional environments of Brazil and the UK. Thus, for this end, variables of the national business system of both countries will be used: corruption transparency, access to credit by countries, quality of the education system and labor relations. After their collection, the data were submitted to descriptive and inferential statistics and hierarchical regression.

Data show that UK companies make more disclosure in CSR than Brazilian companies. Through linear regression, it can be seen that the institutional environment affects disclosure in CSR. In the UK, a country with better educational, labor, political and financial indicators than Brazil, it presented better CSR practices. The findings reveal that the better an institutional environment, the more firms act in CSR. The findings of the research confirm the premise of institutional theory: different institutional fields can modify business performance.

The study analyzed only the disclosure practices of companies in the public sector. Thus, the results should be carefully analyzed, without generalizations for all industry sectors. Therefore, it is suggested that future research looks at other industry sectors as well as other institutional contexts, i.e. other countries.

Multinational companies may have different CSR practices according to the institutional environment in which they operate. For example, companies in developed countries, such as the UK, have greater stakeholder pressure. Given this, managers must adapt their environmental strategies according to the institutional environment in which they operate.

This research contributes to CSR studies in various institutional contexts. There is a consensus in the literature that institutional environments affect firms' CSR practices. However, few empirical studies show results between the national business system and CSR. Thus, the present study intends to fill this research gap.

The purpose of this paper is to investigate the academic side of university–firm linkages, reporting the results of research (called the “BR Survey”, a primary database) conducted in Brazil with leaders of research groups that interacted with firms. The authors analysed the answers from 662 research groups (from both universities and research institutes) to investigate whether the intensity of private funds affects the results of the interactions. The main intent is to answer the following question: Is there a difference between funding sources and the type of results achieved by research groups when interacting with firms?

To verify the impact of some variables on the perception of the main results of university–firm interactions, highlighting the impact of funding sources, the authors present a Logit Model defined with binary dependent variables. The null value is categorized as a “scientific result” (new scientific discoveries and research projects; publications, theses and dissertations; human resources’ and students’ education) and the value 1 is classified as an “innovative/technological result” (new products, artefacts and processes; improvement of industrial products and processes; patents, software, design and spin-off firms).

The authors found that the modes of interaction (relationship types) and some knowledge transfer channels, besides the number of interactions with firms, have statistically significant coefficients, so their values present different impacts on the results of the interaction. The results suggest that the Brazilian innovation policy towards a more active and entrepreneurial role of universities is fostering innovative/technological results from university–firm interactions.

The originality of the study lies on the results found that given the fact that private funding sources do not affect the conventional mission of Brazilian universities – teaching and research – university research groups should be even more incentivized to search for private funds to carry out their research. This may be a solution to the public fund scarcity and may help in reducing the historical distance between universities and firms in Brazil.

The mucilage of the Linum usitatissimum L. seed (Linseed) is one of the natural mucilages that presents a great potential to provide a food hydrocolloid with potential applications in both food and pharmaceutical industries. To increase the yield and quality of linseed oil during its production process, it is necessary to previously extract its polysaccharides. Because of this, flax mucilage production can be made viable as a byproduct of oil extraction process, which is already a product of high commercial value consolidated in the market. Thus, the purpose of this work is to optimize the mucilage extraction process of L. usitatissimum L. using the normal-boundary intersection (NBI) multiobjective optimization method.

Currently, the variables of the process of polysaccharide extraction from different sources are optimized using the response surface methodology. However, when the optimal points of the responses are conflicting it is necessary to study the best conditions to achieve a balance between these conflicting objectives (trade-offs) and to explore the available options it is necessary to formulate an optimization problem with multiple objectives. The multiobjective optimization method used in this work was the NBI developed to find uniformly distributed and continuous Pareto optimal solutions for a nonlinear multiobjective problem.

The optimum extraction point to obtain the maximum fiber concentration in the extracted material was pH 3.81, temperature of 46°C, time of 13.46 h. The maximum extraction yield of flaxseed was pH 6.45, temperature of 65°C, time of 14.41 h. This result confirms the trade-off relationship between the objectives. NBI approach was able to find uniformly distributed Pareto optimal solutions, which allows to analyze the behavior of the trade-off relationship. Thus, the decision-maker can set extraction conditions to achieve desired characteristics in mucilage.

The novelty of this paper is to confirm the existence of a trade-off relationship between the productivity parameter (yield) and the quality parameter (fiber concentration in the extracted material) during the flaxseed mucilage extraction process. The NBI approach was able to find uniformly distributed Pareto optimal solutions, which allows us to analyze the behavior of the trade-off relationship. This allows the decision-making to the extraction conditions according to the desired characteristics of the final product, thus being able to direct the extraction for the best applicability of the mucilage.
