Abstract

Purpose

This paper aims to examine the bioactive compounds and texture properties of cereal bars formulated with banana peel flour during storage.

Design/methodology/approach

Seven cereal bars were produced and stored during 11 months, under vacuum and protected from the light. The total phenolic compounds, the activity antioxidant by ABTS [2,2′-Azino-bis(3-ethylbenzothiazoline-6-sulfonic acid)] method, the DPPH (2,2-diphenyl-1-picryl-hydrazyl-hydrate) method expressed as EC50 (concentration required to reduce the original amount of free radicals by 50 per cent) and texture properties were evaluated over the storage period.

Findings

In general, total phenolic compounds decreased during storage (from 4.19 to 1.11 mg GAE. g-1f.w.). Although the total antioxidant activity (ABTS method) increased during the fifth month, it reduced during storage (from 3.41 to 0.30 µmol TE.g-1f.w.); and the EC50 was not modified in many formulations, though it decreased in other formulations during storage period (from 3913 to 19221 g fruit.g-1 DPPH). The force of rupture began to increase in the fourth month (reaching 62.4 N), and hardness began to increase in the ninth month (reaching 444 N). The formulation and time factors influenced the total phenolic compounds, total antioxidant activity (ABTS method), force of rupture and hardness, while EC50 was only influenced by the formulation (p-value = 0.001). A principal component analysis showed that time had little effect on the most important characteristics considered in description of the cereal bars.

Originality/value

Cereal bars can be consumed up to the third month of storage, considering the texture of the products. Moreover, the presence of bioactive compounds in cereal bars depends on the addition of banana peel flour, which it contributes to the insertion of total phenolic compounds and total antioxidant activity in cereal bars, aggregating functional properties in these products.

Abstract

Purpose

This paper aims to identify the current state of the Portuguese tourism, its opportunities and challenges based on the conclusions of the International Tourism Forum (ITF)/Worldwide Hospitality and Tourism Themes (WHATT) Round Table attended by representatives of the main public and private entities of the tourism sector in Portugal.

Design/methodology/approach

This paper presents and discusses the main conclusions resulting from the ITF/WHATT Round Table. The event was organized by the Institute for Tourism Planning and Development, under the theme “Tourism in 2016: from trends to results”.

Findings

The ITF/WHATT Round Table concluded that the tourism industry worldwide and in Portugal, in particular, is facing major challenges that call for innovative ways of managing the tourism experience. On the other hand, world tourism growth was seen as a reality that will remain, and destinations will have to continue working to achieve better tourists instead of getting more tourists.

Practical implications

This analysis provides knowledge about the current state of the Portuguese tourism, its challenges and opportunities while identifying innovative ways and likely solutions to improve the experience of tourists visiting Portugal.

Originality/value

The profiling of the current state of the Portuguese tourism, its opportunities and challenges contributes to the design of more effective strategies to improve the Portuguese tourist offer and the experience of tourists visiting Portugal.

Abstract

At one end, family farming is seen as important for incentivizing local ­development. At another end, the Brazilian National School Feeding Program (PNAE) is a social assistance policy that provides food and nutrition for students enrolled in public schools. In 2015, the program fed 41.5 million students across the country. In 2009, these two worlds – family farming and school feeding – were connected through a public policy implemented by law. This law defines that 30% of the financial resources for the acquisition of school feeding, transferred by the federal government to states and municipalities, must be spent on items produced by family farming. However, even considering the legal requirement and many of the changes it has brought, many municipalities still do not meet this minimum requirement. In 2015, more than half of the 5,570 Brazilian municipalities, about 54%, did not reach the 30% minimum; that is, over 3,000 municipalities failed to meet that legal threshold. This context raises some questions: Why is the law not effective? What are the social structures that hinder the implementation of this public policy as it was conceived? One of the theoretical frameworks that could sustain such questioning is Structuration Theory (ST; Giddens, 2003). It brings the concept of structure duality, stating that there is no prevalence between social structure and human action, but rather a reciprocity. In this theory, the structure can be distinguished into three dimensions (signification, domination, and legitimation) and the interaction of these dimensions can lead to either transformation or continuity. Using the lenses of ST, our aim is to identify, analyze, and understand the reverberations of this public policy on social practices and how these reverberations could explain this state of things. For this, we conducted a preliminary field research, based on interviews with key agents involved in the school feeding program in a municipality in the Midwest of Brazil. The preliminary results revealed that the change induced by the law reflected on those agents, altering social practices. New procedures were adopted that transformed social practices pertaining to the dimension of signification. Nevertheless, challenges related to logistics (transport and storage), trust, training, and bureaucracy are still hindering the effectiveness of the intended public policy. As a limitation, we were not under conditions to grasp the changes while they occurred because our point of attention is the scenario after the enforcement of the relevant Law. Beyond that, our study uses ST to deal with the resistance of social structures to change even in a scenario of mandatory law enforcement.

Abstract

One of the major issues with reflecting on the COVID-19 pandemic and its effects on work values and dynamics is leadership and management of both material and human resources. We have started this chapter with the challenges of people management in government bodies, corporate outfits, health organisations and educational systems. Relationality and inter-subjectivity have been considered as essential ingredients in preparing for the future.

We have looked at the dimensions of preparedness as mimicking the dimensions of the human being so that there are physical, psychological and spiritual aspects. Physical preparedness directly involves the material resources that make it possible to handle the changes in work hours, technological needs and competence upskilling. Psychological preparedness has been discussed with resilience at the core so that health organisations, businesses and governance target specific aspects of resilience needed for people to thrive. Spiritual preparedness is briefly explained as a continual memory of the capacities of transcendence inherent to the human being so that rapid technological growth never becomes dehumanising. Recommendations are made based on a deeper understanding of these different dimensions in an individual and collective way.

Abstract

Purpose

This study aims to measure the degree of innovation of micro and small industrial companies in the West and Southwest metropolitan regions of the city of São Paulo, through a survey with 203 firms in the metallurgy sector.

Design/methodology/approach

The research had a quantitative and descriptive focus and used as methodology the validated and international approach known as Innovation Radar.

Findings

The degree of innovation in these micro and small companies is low; thus, the authors could not characterize them as systemic innovators. Most of them are little innovative, although some were classified as occasional innovators. The dimensions organization, processes, presence, supply chain and added value were the least developed.

Research limitations/implications

To carry out similar studies in other Brazilian regions, to compare results and draw new conclusions, or even check if the degree of innovation present in micro-firms of these regions would not be even lower; to monitor the evolution of companies through a longitudinal study, to detect improvements in the degree of innovation; and to conduct a qualitative research that can deepen questions on the results of our study, such as the reasons why this type of company does not adopt innovative practices, or even the real suitability of the Innovation Radar model for micro and small enterprises (MSEs). We observed that some dimensions proved to be too sophisticated for these companies, such as R&D investments and the adoption of technological advances.

Practical implications

The study shows that the degree of innovation measured by the Innovation Radar is a useful and initial measure to check an innovative attitude in micro and small companies. It can also drive the actions that should be prioritized to stimulate the culture of innovation in SME. However, it does not allow to answer why this type of organization does not adopt innovative practices as a management attitude. Regarding its contribution, the authors expect that the paper may bring an awareness of managers and owners of micro and small companies for the need to foster innovative practices that can help increase the competitiveness and survival of this type of organization.

Social implications

In Brazil, despite the fact that MSEs represent 98 per cent of the existing companies, and are mainly responsible for job creation, their leaders have a low concern for innovative practices.

Originality/value

The study contributes to identify the degree of innovation of these firms, which comprise a representative and strategic segment of the city’s economy, by checking to what extent an innovative attitude is effectively present in this sector. The theoretical contribution of this study regards the appropriateness of mechanisms or methodologies created to measure the degree of innovation in large organizations. Dimensions such as technological platform, brand, innovative ambience, degree of organization or systematization of processes, which are frequently considered for companies in general, and especially for large ones, are not sufficient or, instead, too sophisticated to allow an effective measurement of the degree of innovation in MSE. Thus, this study provides information for designing more effective ways to evaluate the degree of innovation that take into account MSE’s specificities, which can be considered innovation efforts, such as simple process improvements, professional development of teams, and actions to seize ideas and opportunities, among others.

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 paper aims to analyze the characteristics of Brazilian micro and small businesses (MSBs) and the main lessons derived from the largest small business innovation support program in the country, the Local Innovation Agents – Agentes Locais de Inovação (ALI) Program.

Design/methodology/approach

In total, 34 papers were selected from the Web of Science and Scopus databases (28), as well as from the Revista de Administração e Inovação – RAI (6), a seminal Brazilian innovation journal. The papers were analyzed in terms of the regional context, methodological approach and main findings. Regional complementary analyzes of some program figures were also performed by Spearman correlation and Wilcoxon signed-rank tests.

Findings

The review revealed a low innovation level among Brazilian MSBs and that the platform (incremental product) and brand (marketing) innovation dimensions were the most developed across different regions and industries. Reviewed papers also showed that all MSBs were able to improve innovation over the program independent of previous management and innovation levels, besides positive relationships between management and innovation. The complementary analysis provided a regional panorama of the program figures and corroborated MSBs innovation improvement.

Research limitations/implications

This review analyzed relevant papers and figures related to the program, summarized main lessons and provided future research venues.

Practical implications

Different innovation strategies reviewed may be implemented by MSBs owners. Policymakers may also benefit from the program experience.

Originality/value

Despite the high number of publications and the relevance of the largest Brazilian innovation support program, there were still no literature reviews comprehending the diverse lessons derived from the ALI Program, as well as a regional panorama of the program figures.

Abstract

Purpose

This study aims to explore the firm’s and country-level institutional forces that determine banks’ CSR reporting diversity, during the recent global financial crisis.

Design/methodology/approach

Specifically, this study assesses whether economic and institutional conditions explain CSR disclosure strategies used by 30 listed and unlisted banks from six countries in the context of the recent 2007/2008 global financial crisis. The annual reports and social responsibility reports of the largest banks in Canada, the UK, France, Italy, Spain and Portugal were content analyzed.

Findings

The findings suggest that economic factors do not influence CSR disclosure. Institutional factors associated with the legal environment, industry self-regulation and the organization’s commitments in maintaining a dialogue with relevant stakeholders are crucial elements in explaining CSR reporting. Consistent with the Dillard et al.’s (2004) model, CSR disclosure by banks not only stems from institutional legitimacy processes, but also from strategic ones.

Practical implications

The findings highlight the importance of CSR regulation to properly monitor manager’s’ opportunistic use of CSR information and regulate the assurance activities (regarding standards, their profession or even the scope of assurance) to guarantee the proper credibility reliability of CSR information.

Originality/value

The study makes two major contributions. First, it extends and modifies the model used by Chih et al. (2010). Second, drawn on the new institutional sociology, this study develops a theoretical framework that combines the multilevel model of the dynamic process of institutionalization, transposition and deinstitutionalization of organizational practices developed by Dillard et al. (2004) with Campbell’s (2007) theoretical framework of socially responsible behavior. This theoretical framework incorporates a more inclusive social context, aligned with a more comprehensive sociology-based institutional theory (Dillard et al., 2004; Campbell, 2007), which has never been used in the CSR reporting literature hitherto.
