Abstract

Purpose

The aim of this paper is to describe a project to provide an online web portal that can be used as a front‐end for all university users – students, teachers, staff – and services, library, administration, e‐learning, and e‐mail.

Design/methodology/approach

The profile model proposed is mainly inheritable, defined by profile components with transactional templates, security rules and layout templates. This approach is being tested on a campus prototype portal. The prototype is an underway project in development at our university.

Findings

This paper explains that, even though different from the overall approaches, the basic profile and the profile management system proposed are solid alternatives when addressing personalization of organization users.

Originality/value

This new approach explains how user modelling applications can be integrated into any organization without the cost of reengineering the entire information system already in place.

Abstract

Purpose

This study aims to use sensing technology to observe the learning status of learners in a teaching and learning environment. In a general instruction environment, teachers often encounter some teaching problems. These are frequently related to the fact that the teacher cannot clearly know the learning status of students, such as their degree of learning concentration and capacity to absorb knowledge. In order to deal with this situation, this study uses a learning concentration detection system (LCDS), combining sensor technology and an artificial intelligence method, to better understand the learning concentration of students in a learning environment.

Design/methodology/approach

The proposed system uses sensing technology to collect information about the learning behavior of the students, analyzes their concentration levels, and applies an artificial intelligence method to combine this information for use by the teacher. This system includes a pressure detection sensor and facial detection sensor to detect facial expressions, eye activities and body movements. The system utilizes an artificial bee colony (ABC) algorithm to optimize the system performance to help teachers immediately understand the degree of concentration and learning status of their students. Based on this, instructors can give appropriate guidance to several unfocused students at the same time.

Findings

The fitness value and computation time were used to evaluate the LCDS. Comparing the results of the proposed ABC algorithm with those from the random search method, the algorithm was found to obtain better solutions. The experimental results demonstrate that the ABC algorithm can quickly obtain near optimal solutions within a reasonable time.

Originality/value

A learning concentration detection method of integrating context-aware technologies and an ABC algorithm is presented in this paper. Using this learning concentration detection method, teachers can keep abreast of their students' learning status in a teaching environment and thus provide more appropriate instruction.

Abstract

Purpose

The purpose of this paper is to analyze the discursive resources used to sustain and legitimize the reputation of the mining company Samarco Mineração regarding sustainability, before the environmental accident occurred in 2015.

Design/methodology/approach

The sustainability reports from 2005 to 2014 were accessed for the analysis of the presentation texts, and the discourse analysis method was applied to access the discursive resources employed.

Findings

From the classical concepts of rhetoric, ethos, pathos and logos, it was found that they reinforced the reputation and legitimacy of the company. The ethos is responsible for the company’s image, while pathos triggers the emotional reception of that image, provoking positive expectations. The logos relate the built image and its emotional reception to a rational discourse that values the company’s expertise. The analysis, in the light of the new rhetoric, exposes the strategies to lead the public to accept the image of solidity and confidence given by a reputation respected nationally and internationally.

Research limitations/implications

As a limitation, the quantitative data of the report were not analyzed, since the objective was to analyze the discourse construction, understanding that the research was adequate for the established purposes. For the future, it is suggested to analyze the discourse of the company after the environmental accident in order to verify the strategies used in the same theme; analyze the discourses in other reports published in the Global Reporting Initiative model; investigate how the logic of sustainability report construction based on a standard model can interfere in the formation of reputation and legitimacy of the companies; and analyze the impact of CSR on the strategy of the companies.

Practical implications

The knowledge about the functioning of the language and discourse as an indicative of subjectivity provides a more critical reading and reveals elements implicit in the discourse of the organization. It was verified that the sustainability reports in encapsulated formats allow some stability in the discourse, since companies tend to follow the same line of previous years, even with changes in the organizational structure.

Originality/value

Discourses built by the companies do not always reflect the true operational and engineering situation practiced by them, and that successful and reputed companies can surprise their stakeholders with events of great magnitude that cause significant losses, be they monetary or human lives.

Abstract

Purpose

The general objective of this research was to identify the practices of the mass production industries, on the decisions related to the detection of defective products and to identify relevant criteria, actions, effects and variables to be used in a decision-making model.

Design/methodology/approach

A survey questionnaire was developed and structured in 20 questions, with 18 closed questions and 2 open questions. The questions were constructed based on the literature review, with the identification of 15 theoretical and practical concepts of quality. Seven other information requests were included, concerning the initial characterization of the defective items and industry. The company, the product, the processes and the defects were contextualized, and then the decision-making process was framed, to understand the factors that influenced it.

Findings

The industries of the Industrial Pole of Manaus discard or rework their defective products influenced by promoting the lowest cost and the required quality. The factors with the biggest influence on decisions are rework and disposal costs, and time available for rework and replacement. The main requirements defined for the decision-making model were: 1) compare the rework and discard options, only if the rework reaches the required quality level; and 2) identify and account the effects of defective items on quality, productivity and costs.

Research limitations/implications

Overall, 109 questionnaires were sent, representing 21.3% (109/512) of the companies at the Industrial Pole of Manaus. The respondents represent 14.6% (75/512) of the population.

Originality/value

Defects can occur, requiring a decision that promotes the lowest cost and the required quality. Quality cost models do not show a systematic analysis for identification, accounting, evaluation of effects and criteria associated with the destination of manufactured defective items. Therefore this research was done to fill this gap.

Abstract

Purpose

The purpose of this paper is to propose a competitiveness measurement system for start-ups considering multiple critical success factors.

Design/methodology/approach

The methodological approach uses concepts from key performance indicators (KPIs) and multi-criteria decision analysis (MCDA) based on the fuzzy AHP (FAHP) methodology to weight the criteria related to fundamental points of view (FPVs) and critical success factors (CSFs).

Findings

Data collection was performed with 21 specialists and 28 start-ups, which returned the weights and performance of CSFs and FPVs related to the start-ups’ competitiveness. The results show only one start-up had a highly competitive global performance. In addition, all start-ups showed low competitiveness related to industry 4.0 technologies.

Originality/value

The article collaborates with existing research as a starting point for discussions on the subject, considering that previous research did not address the measurement of the start-ups’ competitiveness level through multiple factors, as developed in this article. In addition, we provide decision-makers and other stakeholders in the start-up ecosystem with a robust measurement system to assess business competitiveness and diagnose the company’s situation.

Abstract

Purpose

The purpose of this paper is to analyse the importance of innovation in the industry; factors that condition technological competitiveness at Magneti Marelli Controle Motor; analyse the risks and opportunities involved in the process of diffusion and management of flexfuel technology.

Design/methodology/approach

The methodological approach was qualitative/descriptive case study, supported by the theoretical framework on risk analysis and strategic analysis.

Findings

In a Brazilian market context, new technologies need to make cars more competitive in cost/price terms. Magneti Marelli had an innovative and important role in the development and implementation of this technology. Thus, it achieved a higher share of market and recognition of its entrepreneurial character.

Originality/value

There are few academic papers that relate the topics risk, strategy and Innovation. Moreover, the paper reports a successful case of Brazilian innovation in the global automotive industry.

Abstract

Purpose

The purpose of this paper is to contribute to the current literature on consumer acceptance of cultured meat and to investigate the main factors that might affect it.

Design/methodology/approach

Data were collected from a sample of 490 consumers in Italy, using a web-based survey. The empirical analysis follows an exploratory approach based on the training and checking of a random forest model.

Findings

An important finding of this study concerns the overall positive perception of cultured meat on the part of the interviewees in a country that is the fifth-largest meat producer at the European level. Age, environmental and ethical issues, and scepticism about new food technologies are the most important factors that guide consumer acceptance of cultured meat. The results suggest that in order to increase cultured meat acceptance it would be important to inform and educate consumers towards new food and new food production methods.

Research limitations/implications

The sample analysed in this study is not representative of the whole national population, as it happens in most papers dealing with new food.

Originality/value

Although the conclusions of this exploratory study cannot be over-generalized, the results provide interesting insights on how to increase cultured meat acceptance in view of the possible development of a new market for cultured meat.

Abstract

Purpose

The paper seeks to examine the evolution of regulatory accounting within the context of the Brazilian electricity sector reforms. The paper traces the process of the reforms and the development of the regulatory accounting system.

Design/methodology/approach

The paper is based on data collected from various documents including those published by the regulator (such as laws, resolutions and technical notes), as well as information from distribution companies and other government agencies.

Findings

It is found that regulatory accounting played different roles under the different electricity sector reforms implemented in Brazil. For example, regulatory accounting was minimally used during the first reform, and this brought a range of problems of implementation and consolidation of the electricity sector model. However, regulatory accounting played an essential role in the regulatory framework under the second reform, and this in part contributed to addressing some of the problems of the sector.

Originality/value

This is the first study that describes and explains the Brazilian electricity sector reforms by analysing the so‐called core issues in regulatory accounting and tariff review process. The paper contributes to the literature by providing a broader picture of the interconnection between regulatory accounting and the regulator's objectives.

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.
