Abstract

Purpose

Decreasing energy demand due to improved building standards requires the development of new biomass combustion technologies to be able to provide individual biomass heating solutions. The purpose of this paper is, therefore, the development of a pellet water heating stove with minimal emission at high thermal efficiency.

Design/methodology/approach

The single components of a 10 kW water heating pellet stove are analysed and partly redesigned considering the latest scientific findings and experimental know‐how in combustion engineering. The outcome of this development is a 12 kW prototype which is subsequently down‐scaled to a 6 kW prototype. Finally, the results of the development are evaluated by testing of an accredited institute.

Findings

Based on an existing pellet water heating stove, the total excess air ratio was reduced, a strict air staging was implemented and the fuel supply was homogenized. All three measures improved the operating performance regarding emissions and thermal efficiency. The evaluation of the development process showed that the CO emissions are reduced by over 90 per cent during full load and by 30‐60 per cent during minimum load conditions. Emissions of particulate matter are reduced by 70 per cent and the thermal efficiency increased to 95 per cent.

Originality/value

The result represents a new state of technology in this sector for minimal emissions and maximal thermal efficiency, which surpasses the directives of the Eco label “UZ37” in Austria and “Blauer Engel” in Germany, which are amongst the most stringent performance requirements in the European Union. Hence this design possesses a high potential as heating solution for low and passive energy houses.

Abstract

Purpose

This research aimed to analyze how information on public policies to mitigate the judicialization of the SUS (Brazilian Unified Health System) have been disseminated via digital media to citizens and stakeholders.

Design/methodology/approach

Under a qualitative and inductive paradigm, the research was based on the search for news on the Google pages. Data were grouped into higher categories to formalize theoretical generalizations.

Findings

Data analysis showed that there are news classified into 11 codes, forming three news groups broadcast as an effort by the programs to legitimize themselves with society: Perceived Quality, Publicity Produced and Results Achieved.

Research limitations/implications

The relationship between the effectiveness of public policies and their dissemination in digital media has implications for the result/legitimacy relationship, not excluding that public marketing can make a program legitimate without having results that confirm its effectiveness.

Social implications

The work provides a means of understanding the dissemination of public policies, in particular, verifying whether these are being provided in order to establish responsible and transparent communication with the citizen or to legitimize public policies without effective results.

Originality/value

The proposed conceptual model is based on four quadrants and represents the relationship between the results achieved by public policies and legitimacy, considering a phenomenon resulting from public marketing. The association between the intensity of these constructs constitutes four themes: fake public marketing, inefficient public policy, deficient public marketing and full public policy.

Abstract

Purpose

This paper aims to discuss the role of information and communication technologies (ICTs) in the effective assessment of the sustainable development goals (SDGs) related to smart and sustainable city initiatives.

Design/methodology/approach

The study is based on a systematic review of the literature within the Web of Science and Scopus databases, comprising the studies about ICTs related to smart and sustainable city initiatives and sustainable assessment.

Findings

The main results point out that there are several different ways of assessing SDGs performance related to ICTs use in smart and sustainable city initiatives. However, the effectiveness of these assessments can be questioned. The intensive use of technology understood as the core of smart and sustainable cities does not imply an improvement in sustainability unless these technologies are strategically addressed to underpin those objectives. Moreover, not all SDGs have considered the use of ICTs in their targets.

Research limitations/implications

The scope of the study is limited to “how” the information is used and managed, rather than analysing the sustainable performance itself. As a limitation, the findings and conclusions do not consider other sources of studies, such as grey literature.

Practical implications

This study suggests some requirements for providing better and more reliable sustainable assessment, making smart and sustainable city initiatives more correlated with the SDGs.

Social implications

By acknowledging the difficulties associated with SDGs assessment, concerning the municipal level, the study offers valuable insights into the effectiveness of public policies and public management. Besides, the findings shed some light on if and how the use of ICTs can effectively enhance sustainable development issues.

Originality/value

This study offers valuable contributions to the literature by providing a collection of insights regarding how the ICTs may genuinely lead to a sound assessment of sustainable development, especially regarding the SDGs.

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

To promote access to their services, health-care companies provide various communication channels to their customers (beneficiaries) to enable the receipt of requests, such as authorization for examinations, procedures and hospitalizations. Under the approach of innovation studies, the management of customer relationship channels for health-care companies is characterized as a knowledge-intensive business service (KIBS). The purpose of this study is presenting innovation as a strategy to increase customer service productivity, as well as the monitoring of the quality of the service, the generation of health information for beneficiaries and compliance with the regulation set by the Brazilian National Health Agency (ANS).

Design/methodology/approach

The study is characterized as an applied research, as it proposes solutions to problems faced by supplemental health-care companies using the strategy of action research, i.e. an independent, social research with an empirical basis.

Findings

The result of this study shows that a computerized health-care system can increase productivity by 21.96%, and it presents an innovative solution for health-care companies to guarantee the process of meeting the demands and requests of their beneficiaries, ensuring the compliance with ANS regulations.

Practical implications

These results can be replicated to other healthcare companies and contribute to those seeking innovation, increased productivity and quality improvements in their services.

Originality/value

This work was also motivated by the lack of lstudies in the areas of health-care companies in Brazil.

Abstract

Purpose

The purpose of this paper is to discuss the influence of glamour, scopophilia and self-sexualisation in luxury celebrity endorsement.

Design/methodology/approach

In step 1, an experimental study was conducted with 100 respondents assessing the response towards manipulated print ad stimuli operationalizing the influence (in general terms) of lay out, endorser’s beauty pattern, body language (cool, smile appeal, sex appeal and disruptive), gazing and landscape. In step 2, respondents evaluated their response towards five perfume print ads retrieved from real advertising campaigns with different brand personalities (DKNY, Moschino, Chanel, Gucci and Boss).

Findings

The ideal copy strategy is: a couple of brunette Caucasian endorsers; “close-up” photo; sexy body language; indirect smiling gaze; and urban landscape. Multiple regression models were built for each ad/brand (personality) in order to predict the willingness to pay for a bottle of perfume.

Research limitations/implications

The paper suggests a holistic theoretical framework describing the influence of celebrity characteristics, advertising copy strategy, social-cultural trends and brand variables in the advertising processing.

Practical implications

Advertising copywriters and brand managers must control the role of glamour and the self-consciousness of women seduction power in branding advertising.

Social implications

Glamour, scopophilia or self-sexualisation are three different concepts which have a lot of sociological implications because they influence the way as the society perceive the role of women as endorsers in advertising, but also in other life dimensions.

Originality/value

This paper fills a gap in the literature, since this paper make an innovative analysis of the influence of these recent post-modernist socio-cultural trends.

Abstract

Purpose

In this paper, the authors aim to explore the relationship between the concepts of Industry 4.0 and circular economy (CE) as a contribution to the management decision on emerging countries. By analyzing the trends of scientific production to ascertain the interface of both constructs, the purpose of this paper is to identify limitations for Industry 4.0 and CE implementation in Brazil, as well to present an original framework and strategic pathways to overcome limitations for emerging countries.

Design/methodology/approach

Supported in the Brazilian case, the authors draw a framework using the structuralism approach to indicate pathways for the strategic positioning of emerging economies that consider their limitation and potential for competitive advantage. By understanding country-related limitations such as social and economic contingencies, the authors conceive a structure of implications for Brazil’s capacity to develop CE in the digital era.

Findings

Results show that Brazil has a reasonable, institutional and stable environment, as well as strong regulatory policies for solid waste that can stimulate CE in the country. However, it requires more communication between actors, especially public and private institutions, performing long-range relationships. Also, the country requires consolidation of industrial policies and investments in the remanufacturing process in the supply chain. Likewise, despite Brazil’s ability to take advantage of CE’s benefits, the country presents a huge lack of qualification to fulfill the competences that the digitization process demands. Economically, Brazil has been fighting against an economic crisis since 2014 that has limited general investments, especially in the industrial sector. Industry presents low performance and decreasing GDP participation, which leads to constant overseas production transfer as a consequence of the workforce’s high costs.

Research limitations/implications

The authors can affirm that Brazil is far behind developed countries in searching for the capacity to provide CE through technological industrial change. The main problems are related to the lack of articulation of public and private spheres to promote new digital business models. Therefore, the structured framework enables managers and public agents to provide solutions and to properly address supply chain bottlenecks in emerging economies.

Originality/value

Exploring the relationship between the concepts of Industry 4.0 and CE through the specific lens of the structuralist method, this work can contribute to the management decision on emerging countries, looking into four important perspectives: political, economic, social and technological.

Abstract

Purpose

The purpose of this study was to investigate the effect of a dietary probiotic on the growth performance and survival rate of Litopenaeus vannamei shrimp. Furthermore, the microbial quality of shrimp was evaluated.

Design/methodology/approach

Shrimp were divided into treatment and control groups (each group containing 45 shrimp). They were fed for four weeks with a control diet alone or supplemented with a commercial probiotic (Protexin®). At the end of the trial, they were assessed for survival rate, weight gain, average daily gain and specific growth rate. Samples of tail meat were also provided aseptically from peeled shrimp for bacteriological analysis including the count of Staphylococcus aureus, enterococci, Clostridium perfringens, fecal coliform, Salmonella, Escherichia coli, Listeria monocytogenes and total bacterial count.

Findings

The growth performance of the probiotic-treated group significantly (p < 0.05) increased at the end of the experimental period. However, no significant differences were observed for the survival rate between the groups (p > 0.05). The count of C. perfringens and the total bacterial count in shrimp supplemented with the probiotic were significantly lower than those of controls (p < 0.05). The count of coliforms and S. aureus was not significantly different between the groups (p > 0.05).

Originality/value

It could be concluded that the probiotic bacteria have the potential to stimulate the growth performance of L. vannamei. They can also be used for biological control of food-borne pathogens and improve the microbial quality and safety of shrimp at the farm level.
