Abstract

Purpose

The purpose of this paper is to propose a systematic study to formulate the cost of prototypes manufactured through rapid prototyping (RP) an fused deposition modeling (FDM) 3D printer in a university lab.

Design/methodology/approach

The paper has a theoretical‐conceptual approach. This approach is carried out by studying and proposing a methodology for calculating the cost of pieces prototyped an FDM 3D printer.

Findings

This work originated from a gap in literature to establish a way to calculate the price of RP pieces from FDM 3D printers in universities' labs, since no similar work has dealt with this RP technology and has not taken into account the costs of post‐processing step. The results suggest that the formulation may be used to calculate price of prototyped pieces through FDM 3D printer.

Research limitations/implications

The systematic approach proposed by this research to formulate cost for the RP pieces is initially oriented only to modelling technique by FDM 3D printer. Considerations on operator's and designer's hourly rates are those practiced in Brazil, which may differ from other countries.

Originality/value

The paper's scientific contribution is a specific formulation to calculate price of prototyped pieces through FDM considering the post‐processing way, which differs from previous published works. The formulation implies that the execution times and the amount of material used were obtained by internal calculation of the tested machine. This is different from what has been already studied by previous literature which considers an index that encompasses the machine operation cost in function of time. It is aimed that the results obtained here are accurate, since error margins of the process variables are reduced.

Abstract

Purpose

The purpose of this paper is to present a structured way for the definitions of the Process Failure Mode and Effect Analysis (FMEA) attributes, such as potential failure mode, potential cause and potential effect, in order to make it simpler to define the controls and scores.

Design/methodology/approach

This study performs, through a case study in incoming inspection of raw material, the comparison of a conventional application of the Process FMEA with a proposal based on the concepts of process approach defined by ISO 9001.

Findings

Even written in a form similar to a script, the application of Process FMEA is a very complex activity and, like most quality tools, before being applied, FMEA should be clearly understood by the team. One way to facilitate this understanding is considering the sequence of events in the failures analysis to understand their causes and effects, just as are the sequences of inputs and outputs in the definition of the process approach addressed in ISO 9001.

Originality/value

This paper shows a simple way to better structure Process FMEA, facilitating meetings with multidisciplinary teams.

Abstract

This chapter examines the professional identities of Brazilian journalists. It does so through an analysis of the growing professional autonomy of journalism from 1950 to 1990 through the life stories of 10 intellectual-journalists, individuals whose journalistic activities have crossed over into other intellectual fields.

This study applies a symbolic interactionist framework to understand how these actors managed their reputations and careers within the intellectual world. The narratives were taken from qualitative semi-structured interviews, and supported by additional research such as interviews, biographies, and articles which have been published about their lives.

The life stories were compared to the extensive structural changes affecting the world of journalism and the world of intellectuals in Brazil. This comparison revealed gaps between these two spheres of practice, within which the ambivalent form of journalists’ identities have been constructed.

This chapter offers two contributions to the study of Brazilian journalists. From a theoretical and methodological viewpoint, it advances beyond other studies that focus more on the prevailing representations of journalists’ professional identities and their role in society. From an empirical standpoint, it describes the complex negotiations between the worlds of journalism, culture and politics. This chapter also reexamines the current dominant explanation for the changes in Brazilian journalism. It shows that building careers and new levels of interpersonal cooperation for intellectuals and journalists has been a slow process. Ultimately, this development has left some behind, especially those actors stretched between multiple professional identities such as those who self-identify as intellectual-journalists.

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

The objective of this chapter is to outline an integrating picture of the situation, representativeness, contradictions, and challenges that the treatment of diversity assumes in Brazilian society and in its organizations. The aim is to reply to the research question: “How are public policies and organizational practices constructing ways of inserting and valuing the diversity of Brazilians?” We provide a brief background of the changes in the global and Brazilian contexts over the last few decades and analyze the demographic data presented in the 2010 Census and in studies on diversity that were published in the main periodicals in the Administration area in Brazil, between 2000 and 2014 with regard to the segments most widely studied in the academic literature: Afro-descendants, homosexuals, the elderly, Indians, women, and people with a disability. The conclusion reached is that, in a short period of time, Brazil has made great strides in constructing the mechanisms and legal devices for recognizing the rights of its diverse population and that private companies are in the initial stages of introducing diversity programs.

Abstract

For the longest period of its history, the university was the guardian and transmitter – not the producer – of knowledge. This relatively recent change of transmitting canonical knowledge and generating new knowledge is normally associated with Wilhelm von Humboldt. Other highly influential university models were provided by France and Great Britain. The association of certain types of universities with particular countries is a strong indicator of the intricate link between nation-state and education. Hence, the history of tertiary education and its elite institutions, the research universities, must be considered in relation with a sea change in educational history – the gradual emergence of national education systems. Only under the conditions of the by now standard form of organizing modern societies as nation-states did education become a central institution (Meyer, Boli, Thomas, & Ramirez, 1997) collapsing individual perfectibility and national progress. The nationally redefined university was integrated into the education system as its keystone while also being considered the motor of societal development. From a social history perspective, the latter aspect in particular indicates the pragmatic (training professionals, imparting military and technical knowledge, etc.) and symbolic expectations, “myths” of the nation-state that have been so aptly described and analyzed in numerous macro-sociological neo-institutionalist studies (Meyer, Ramirez, & Soysal, 1992; Meyer et al., 1997; Ramirez & Boli, 1987). In a macro-phenomenological perspective, the term “myth” is used to denote a fundamental change in the self-description of European society which since the late eighteenth and early nineteenth centuries no longer views itself as consisting of separate collectivities divided from each other by social origin – as was the case under feudal conditions – with each collectivity providing itself the necessary education for its members or being provided for by others in the case of neediness. Instead, as a result of a number of material and immaterial changes, society now defines the individual as its key unit, with the nation being consequently the aggregate of individuals and not of collectivities and the state redefined as the guardian of the nation. This conception might be taken as a kind of overlapping area which includes different approaches, such as Michel Foucault's concept of the disciplinary society (Foucault, 1977), Balibar and Wallerstein's (1991) deliberations on the relation between race, class, and nation, and Benedict Anderson's (1991) description of nations as imagined communities. All these studies could be taken as sharing the notion of “constructedness” (cf. Berger & Luckmann, 1972) of modern society with the neo-institutionalist perspective. The concept of a “world polity” which encompasses the “myths” society is based on, the overall notion of a cognitive culture, which takes Max Weber's concept of rationality as a point of departure, is identified as the basis of isomorphic change in the organizational structure of modern education systems (cf. Baker & Wiseman, 2006). However, the strong emphasis on international, world system embeddedness of nation-states and their education systems is not to be taken as a unidirectional dependence on external forces. While modern nation-states originate from and remain tied to international dynamics and developments, they are conceived as unique entities. For most of their history, modern nation-states have been preoccupied with making themselves distinct from each other. Thus, while international competition has always been present, looking abroad traditionally meant reworking, adapting, and reshaping what was imported, or borrowed (Halpin & Troyna, 1995; Steiner-Khamsi, 2004). This is true for education as well as for other areas of society.

Abstract

Purpose

Erosion is the main cause of soil and water degradation, which demands investments for the recovery of such natural resources. The purpose of this paper is to quantify and spatialize soil losses in a municipality with large areas of monoculture of sugarcane.

Design/methodology/approach

The Universal Soil Loss Equation was applied for the identification of areas susceptible to erosion in the municipality of Jahu, SP, Brazil. Soil maps, statistical census data from Brazilian Institute of Geography and Statistics, radar images from SRTM, rainfall data from Fatec-Jahu hydrometeorological station and digital satellite images from Landsat 5 TM were used for the analyses. Four basic parameters were evaluated: topography of the terrain, rainfall erosivity, soil erodibility, and soil use and management factors. The analyses were conducted in the Geographic Information System (ArcView software).

Findings

The results show most of the municipality (91 percent) consists of areas of erosion potential. However, the remaining 9 percent can potentially produce 40 percent of the sediment load, which indicates the need for conservation practices and environmental recovery for a reduction in the erosion process acceleration.

Originality/value

In view of the expansion of sugarcane culture in the cities of São Paulo, the results show the importance of a master plan for new areas of sugarcane planting and the need for restoration of riparian vegetation in the surrounding streams and springs for the reduction of erosion.

Abstract

Purpose

Innovation is a constant attribute in the management processes of technology-based companies (TBCs), mostly small and young, and plays a relevant role in their competitiveness and survival. However, the authors assumed that the characteristics of innovation practices differ between incubated and post-incubated companies, in such aspects as formality, type, posture and strategy. The purpose of this paper is to report the innovation practices identified in small TBCs in the incubation and post-incubation periods (graduate companies).

Design/methodology/approach

To achieve the purpose, the authors carried out a multiple case study with four TBCs, two incubated and two post-incubated (graduate); the study was qualitative and exploratory, and the authors collected data with their managers.

Findings

The results show that these companies have high levels of innovation, which is a determinant factor for their presence in the business market; they create technological innovations in products and services, mostly incremental, such as improvements in existing products or reduction of internal costs of manufacturing. In addition, the results also show important features of the innovations, such as the interaction with other incubated companies and with universities and research centers.

Originality/value

The authors conclude that there were changes in innovation practices, in the transition from incubated to graduate companies, such as the formalization of processes, a shift in focus toward the customer and an increase in resources and in projects’ relevance.

Abstract

Purpose

This paper aims to measure and unveil the relationship between customer satisfaction and efficiency levels in the most relevant Brazilian airports.

Design/methodology/approach

The authors utilize a two-stage network DEA (data envelopment analysis) and AHP (analytic hierarchy process) model as the cornerstones of the study. The first stage of the network productive structure focuses on examining the infrastructure efficiency of the selected airports, while the second stage assesses their business efficiency.

Findings

Although the results indicate that infrastructure and business efficiency levels are heterogeneous and widely dispersed across airports, controlling the regression results with different contextual variables suggests that the impact of efficiency levels on customer satisfaction is mediated by a set of socio-economic and demographic (endogenous) and regulatory (exogenous) variables. Furthermore, encouraging investment in airports is necessary to achieve higher infrastructural efficiency and scale efficiency, thereby improving customer satisfaction.

Originality/value

There is a scarcity of studies examining the relationships among customer satisfaction, privatization and airport efficiency, particularly in developing countries like Brazil.
