Abstract

Purpose

This paper aims to present a proposal for the restoration of a silver crown by means of fitting pieces produced by the process of 3D modelling and rapid prototyping. It also analyses the benefits of this procedure in restoration of objects weakened by corrosive processes.

Design/methodology/approach

Elemental chemical analysis was carried out in the alloy used in the manufacture of the crown and the constructive and corrosive processes present were studied. Three fitting pieces were modelled and prototyped in wax casting by the stereolithography apparatus system aiming to restore the part and protect the original metal against impacts and external tensions which could speed up some deterioration processes.

Findings

The procedure presented in this paper has shown that formal and dimensional accuracy, only achieved by means of 3D technologies, made the restoration and mechanical stability of the crown possible without the use of adhesives or welding.

Originality/value

The proposed procedure is a new restoration alternative which causes minimal impact to the object and abides by the main standards for modern conservation. It is made with metal which is compatible with the original piece, retractable and easily identifiable.

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 is an excerpt from a countrywide study entitled “Leisure in Brazil: representations and realizations of daily experiences”, which aims to investigate what Brazilians do in their leisure time, what they would like to do and why they do not do it.

Design/methodology/approach

Specifically, in this paper, the authors analyze data referring to the elderly population from southeastern Brazil. Sampling of the national survey comprised representative quotas of the population, considering region and state, and, in each state, quotas of sex, age, education level and family income, according to data obtained by IBGE in 2010. A total of 2,400 interviews were conducted in total. For the present study, the 91 interviews conducted with elderly subjects from the Southeast region of Brazil were considered.

Findings

The majority of participants understand leisure as a time for resting and fun and have physical/sports interests as their favorite leisure activity during the week. On weekends, social and tourism interests stand out, and idleness stands out in the preference of this public during the holiday period. Lack of time and financial resources are the main barriers to the access to and permanence in the desired leisure practices.

Originality/value

Having knowledge of the relationship between leisure and aging in Brazil is a way to contribute to the potential of this stage of life, based on the quality of life and continued learning provided by the content they enjoy.

Abstract

Purpose

The purpose of this paper is to evaluate the retention rate of vitamin C and carotenoids in vegetables submitted to heat treatment.

Design/methodology/approach

Samples of carrot and broccoli were submitted to conventional cooking, steaming, microwaving and autoclave. Ascorbic acid concentrations were determined according to the methodology of Zhang and Hamauzu. The extraction of carotenoids was done using the methodology of Niizu and Rodriguez‐Amaya. The formula of Murphy et al. was used to calculate the retention rate of vitamins.

Findings

The highest retention percentage of ascorbic acid, α‐carotene, β‐carotene and lutein in carrots was obtained using microwave cooking. In the case of broccoli, the best retention for α‐ and β‐carotene was by steam cooking, whereas ascorbic acid was best preserved in the autoclave and lutein by conventional cooking.

Practical implications

Ascorbic acid and carotenoids are compounds present in vegetables relevant mostly from a therapeutical point of view, as they appear to be associated with the prevention of many diseases. However, these vitamins are lost during the cooking process, which is of great importance in developing countries where deficits of these nutrientes are quite common in the population.

Originality/value

The results obtained in this study indicate that the cooking technique of choice is of fundamental importance not only at home but also for the food industry, considering the increasing consumption of processed foods.

Abstract

Purpose

The purpose of this paper is to analyze the urban resilience capacity and its relations with the economic, social and environmental well-being in smart cities in the state of São Paulo (SP), particularly after the 2008 financial crisis.

Design/methodology/approach

Concerning its objectives, this study is characterized as descriptive. From the point of view of technical procedures, the research is bibliographic, and regarding data collection, it is documental. The approach of this research is quantitative, since it uses the statistical method. The sample was made up by 62 smart cities located in SP. The analysis comprised the period from 2010 to 2015.

Findings

The urban resilience pillars influence the economic well-being represented by the gross national product, in 58.8 percent, social well-being represented by the life expectancy of the residents of the smart cities, in 71.7 percent, and in environmental well-being indicated by CO2 emissions, in 21.5 percent.

Research limitations/implications

They are related to the researchers’ decision about the methodological design.

Practical implications

This study was limited to smart cities in SP listed in the RBCIH (Brazilian Network of Human Smart Cities), and may be extended to other cities in other Brazilian states.

Social implications

How resilience dimensions related to economic, social and environmental well-being such as poverty, food security, health, well-being, education quality, climate changes, and the like, were measured, which can be investigated in future research studies.

Originality/value

Despite its growing popularity worldwide, the urban resilience pillars and their relationship with human well-being in smart cities in the national context are little investigated, making this research original.

Abstract

Purpose

The purpose of this paper is to evaluate the pathological, biochemical and redox state parameters of liver tissue in Wistar rats treated from birth to adulthood (119 days) with cafeteria diet.

Design/methodology/approach

During the lactation, 6 liters of Wistar rats (dam + 8 pups each) were fed one of two diets: control (CTRL; n = 3) or cafeteria (CAF; n = 3) diets and water ad libitum. After weaning, the males were placed in individual cages, receiving the same diet offered to their respective dams (CTRL or CAF; n = 18) until adulthood. The following parameters were evaluated: absolute and relative liver weight; blood, liver and feces biochemistry; liver histology; and redox state of the liver.

Findings

When assessing the relative and absolute organ weight, no significant differences were found between the groups. The Cafeteria group exhibited higher values of serum LDL-c (p = 0.008), VLDL-c (p = 0.03) and triglycerides (p = 0.01), as well as several micro and macrovacuoles of fat accumulation, higher hepatic lipid (p = 0.03) and cholesterol (p = 0.0001) levels regarding Control group. Cafeteria group showed greater expression of glutathione-s-transferase (p = 0.03) and superoxide dismutase (p = 0.005) enzymes compared to the control group. In the case of the markers of oxidative stress, there was no difference between the groups.

Originality/value

A simple and standardized cafeteria diet caused an accumulation of fatty acids in liver tissue, inducing a state of hepatic steatosis besides an increased expression of antioxidant enzymes.

Abstract

This research is about the evaluation of organizational risks in the hospitality sector, using the experience of a guest with visual impairments. The objectives of this research are to (1) identify if the previous expectations of a guest with visual impairments trip will be exceeded in the final; (2) classify organizational risks in the hotel sector; (3) verify if there are direct impacts on the travellers' future behaviour, such as destination recommendation and intention to return to the destination. Despite of the fact that organizational risks are composed by transport, hospitality and tourism attractions (tourism players can jeopardize the success of a travel experience), this research will only focus on the hospitality sector. To assure the achievement of the referred objectives, a case study will be used based on the analysis of the experience of a Portuguese guest with disabilities, who traveled alone, around Europe, with a guide dog. His expectations, constraints and risks will be analysed through a deep-depth interview, in which questions are organized from the literature review. Finally, it is expected that this exploratory research helps to find new avenues for the study of organizational risks, more precisely, hospitality risks for disabled people.

Abstract

Purpose

The purpose of this paper is to investigate if shared brands provide sustainable competitive advantage according to an adapted valuable, rare, imitability/replaceability and organization (VRIO) model to the Brazilian wine sector in the opinion of the government agencies, associations and managers of the wineries.

Design/methodology/approach

This study was based on a qualitative and exploratory research, based on in-depth interviews. Fine wines that have geographical indications and are located in the Brazilian state of Rio Grande do Sul were analyzed and content analysis was used to explore data.

Findings

It was concluded that shared brands in the Brazilian wine sector can be considered a source of sustainable competitive advantage according to the resource-based view.

Research limitations/implications

Qualitative research has the aspect of the subjectivity of the researcher when analyzing the data.

Practical implications

The government agencies, associations and wineries can improve the production process and seek certified products for commercialization in the domestic and foreign markets. These contributions may also, in practice, be used by other sectors and countries.

Originality/value

This work contributes to the understanding of the shared brand’s concept, including geographical indications, collective brands and the sector brands. The proposition that shared brands provide sustainable competitive advantage, according to an adapted VRIO model was confirmed. Barney’s VRIO framework (Barney, 1991, 1995) hitherto thought for individual companies, has the letter “O” of Organization replaced by the letter “A” of Association, becoming VRIA. The authors found that the four conditions that form the here proposed acronym VRIA are valuable, rare, imperfectly imitable/replaceable and association.

Abstract

Purpose

The purpose of this paper is to collectively measure and compare the efficiency of Brazilian and American soybean transport corridors, from farmers to export ports, using the data envelopment analysis (DEA).

Design/methodology/approach

This paper aims to determine routes from main producing micro-regions to main export ports, specifically using slack-based measure and variables that represent the three pillars of sustainability (economic, social, and environmental). The choice of variables was guided by literature review and analyzed through the principal component analysis. After the application of the model, the quantitative tiebreaking method of the composite index is applied.

Findings

The findings are coherent with a global report that compares soybean transportation in both countries (Brazil and USA). Efficient routes and corridors tend to present short distance truck trips and long distance train or barge trips. The efficiency of the inland waterway trips depends on how many barges are used in the same expedition. Routes with more than three modes tend to be inefficient which suggest that there is a limit for multimodality.

Originality/value

Corridor benchmarking is a rare topic in the literature and previous works normally focus on some specific and limited corridor performance characteristics, such as cost. The main contribution of this research is that it expands the discussion regarding corridor benchmarking and it focuses on efficiency as a whole. The paper also proposes a method that can be applied in different logistics contexts, like expanding the study to different countries. More specifically, this method could be used in infrastructure investments programs.

Abstract

Purpose

The study compares how distinct mechanisms that connect pre-established policy objectives to professionals' practices, and the health policy implementation context influenced different approaches to frontline staff participation. The authors analysed 26 teams in six cities from two Brazilian states, during the last cycle of the National Program for Improving Access and Quality of Primary Care (PMAQ).

Design/methodology/approach

About 172 in-depth interviews were conducted with frontliners – community health workers (78), nurses (37), doctors (30) – and managers (27). Interview guides were based on key issues identified in the implementation and pay-for-performance (P4P) literature. Drawing on thematic analysis and synthesis of the literature, three types of participation mechanisms were identified: relational, motivational and incremental learning. They were analysed considering distinct contexts at the local level to understand how they influenced different forms of participation: mere adherence, result-oriented and transformative.

Findings

Administrations with stronger institutional organizational structures were able to control work processes and reduce professional discretion. However, sustained participation was more likely where there was greater integration between management and frontline health care teams. Motivation based only on financial incentives could not bring about transformative participation. This depended on the degree of professional's ideational motivation towards primary care. Finally, contexts with unfavourable working conditions tend to demotivate professionals, but incremental learning helps teams cope with these obstacles.

Originality/value

The study overcomes gaps in the literature in relation to PMAQ's implementation process. Overall, the study delves into which/how mechanisms alter frontliners participation in performance-oriented health programs.
