Abstract

Purpose

Food waste has received attention during the last decade, especially due to its environmental and social impacts. An important contributor to food waste is consumers’ low preference for purchase fruits and vegetables with unusual appearance, products with damaged package and products close to the expiration date, technically called suboptimal food products. Researches show that consumers tend to reject these products when buying food, increasing avoidable food waste. However, consumer considerations when deciding to buy or not to buy suboptimal food are still unknown. The purpose of this paper is to use two different approaches to investigate consumers’ perceptions towards suboptimal food and how they impact their acceptance.

Design/methodology/approach

The first part of the study involved a qualitative analysis of participants’ open-ended responses (282 answers), where participants were asked to write down the impressions they had about three suboptimal food images. The second phase explored consumers acceptance of suboptimal food through a focus group discussion.

Findings

Results reveal that considerations about suboptimal food are divergent, with some participants rejecting them because they are impelled to search for perfection when buying food products. However, some individuals are disposed to accept suboptimal products, mainly because they have concern with the environment and cook abilities.

Originality/value

As a whole, this study contributes for food waste reduction strategies and has implications for marketing actions.

Abstract

Purpose

This paper aims to provide a method and decision support tool to enhance swift reconfiguration of Plug&Produce (P&P) systems in the presence of continuously changing production orders.

Design/methodology/approach

The paper reviews different production scenarios and system design and configuration methods and more particularly specifies the need of decision support tools for P&P systems that integrate configuration and planning activities. This problem is then addressed by proposing a method that helps reduce the solution space of the reconfiguration problem and allows the timely selection of the most promising reconfiguration alternative.

Findings

The proposed method was found to be helpful in reducing the reconfiguration alternatives that need to be considered and in selecting the most promising one for different orders. The advantages and limitations of this method are identified, and an illustrative test case of the approach is presented, corroborating the method applicability in the absence of large queues in the system.

Originality/value

This paper addresses a less explored domain within the P&P systems research field, which is the system reconfiguration. It proposed a method to support system validation and reconfiguration jointly with an illustrative test case. This represents an original contribution to the P&P research field, and it can have impact in improving agility and decreasing the complexity of reconfiguration activities to cope with constantly changing production orders.

Abstract

Purpose

This article presents an investigation of the suitability of using quantitative or qualitative data for individual competencies assessment. Specifically, the primary purpose of this article is to identify if the results provided by quantitative and qualitative instruments focused on individual competencies are convergent.

Design/methodology/approach

In order to do the investigation proposed, a survey on individual competencies comprising a group of employees of the administrative area of a steel company was carried out. A total of 268 evaluations were collected and analyzed.

Findings

The analysis of the employee's performance appraisals provided by ratings and narrative comments indicates a low correlation between these assessments. The reasons for such low correlation include the qualitative assessments variability, the restricted list of competencies used in the quantitative assessments and the analytical format of quantitative assessments.

Originality/value

The study indicates that quantitative and qualitative assessments should be carried out jointly so that they can generate more comprehensive results. When the combined use is not possible, the quantitative approach is better suited for assessing performance, while the qualitative approach provides more valuable insights for boosting people development processes.

The purpose of this paper is to define the individual leadership competencies that are necessary to implement and sustain lean systems, based on a multi-method approach.

Abstract

Purpose

The purpose of this paper is to define the individual leadership competencies that are necessary to implement and sustain lean systems, based on a multi-method approach.

Design/methodology/approach

Data collection involved a literature review of lean competencies, interviews with four experts from the university and the industry, and an empirical survey answered by 91 respondents, who represented companies from several sectors. These techniques provided a mix of qualitative and quantitative data, which set a basis for identifying a list of competencies and discussing its validity.

Findings

In total, 16 lean leadership competencies were identified and validated, in terms of content validity, face validity, and predictive validity. Regarding this latter validity type, the survey results indicated that the competencies are positively associated with key operational performance indicators, organizational maturity level of lean, and leaders’ experience with lean systems.

Practical implications

The identified list of competencies may be a basis for the development of formal lean leadership development programs. The list may also support the design of tools for assessing the competencies of leaders in lean companies.

Originality/value

A list of 16 lean leadership competencies was developed based on a verifiable research method that used a mix of data collection techniques. This methodological approach is a distinctive characteristic in comparison with earlier studies, which did not include an empirical validation of the competencies.

Abstract

Purpose

The purpose of this paper is to describe the activities needed to meet specified requirements to assist laboratory staff running tests and calibrations and to obtain ISO/IEC 17025 accreditation.

Design/methodology/approach

The relevant literature that contributes to establishing activities that help laboratory staff to obtain ISO/IEC 17025 accreditation was studied. Laboratory researchers specializing in electro-medical equipment quality control were questioned about the criteria to be observed when selecting, developing and validating analytical steps.

Findings

Results revealed the analytical method criteria to be observed, which demonstrated their essentially quantitative nature.

Originality/value

This study presents a model that improves selecting, developing and validating analytical steps and contributes to producing reliable test and calibration results. These improvements can help laboratory testing and calibration to meet clients’ needs, satisfy specified requirements and provide reliable results.

Abstract

The evolution of the concept of landscape to incorporate components like cultural and socio‐economic factors, in addition to the natural and aesthetic features, influenced the perception of landscape as a resource. On the other hand, the relationships between territorial features as well as the understanding of their temporal dynamics determine the significance of these features for the quality of a landscape and, consequently, for its conservation. This implies that all components – natural and physical, but also cultural and visual – upon which landscape quality is assessed, ought to be considered and studied globally. Natural resources and cultural heritage, however, are usually considered independently when developing protected areas management plans. Here, we present a methodology developed for the Monte da Guia management plan, which allows the interrelated analysis of landscape factors such as geology, geomorphology, pedology, flora and vegetation cover as well as the cultural and visual characters. Using the concepts of biophysical sensitivity and visual quality, we evaluated the relevance of these various factors for the determination of the state of equilibrium/degradation of a landscape, and hence for its conservation value. This methodology may contribute to the development of improved zoning maps and management guidelines determining land use and management strategies for the conservation of individual resources that, together, determine landscape quality.

Abstract

Purpose

This paper aims to present a model that maps the relationship between factors and process stages of the knowledge transfer (KT) between new product development (NPD) teams.

Design/methodology/approach

The model was constructed through a quantitative evaluation with scholars and practitioners of the NPD field. To evaluate the model and its usefulness, a practical application was carried out in two large Brazilian companies.

Findings

A relationship model between 16 main influence factors and 11 stages of the KT process was obtained. It could be seen through the practical applications that the model helps companies to identify and prioritize improvement opportunities in the KT between NPD teams.

Research limitations/implications

Prior studies had been concerned with the analysis of KT factors, but considering KT as an isolated act. So, this work has advanced in the deployment of the KT stages and the relationship of those with different influence factors.

Practical implications

This paper brings an important practical contribution, once several academic works have been concerned with to demonstrate relationships among factors, but few have shown how these results could help to solve practical issues observed in companies.

Originality/value

Results presented in this paper enable the extension of comprehension about the KT phenomena in the NPD process. Furthermore, this paper shows how the proposed model can be used as a decision tool to guide a diagnosis and detect improvement opportunities in KT between NPD teams.

Abstract

Presents a new procedure for quality control and quality assurance in scenarios where several variables and attributes have to be monitored. The proposed procedure, named integrated process control, begins with the definition of control stations on the production line, where a single chart that aggregates several variables and attributes is used. This procedure is complemented by using Pareto charts, which determine the quality characteristics contributing the most to the number of defectives. The integrated process control also uses traditional control charts; however, these are used selectively following the indication of the Pareto charts. The joint use of these tools facilitates the identification and solution of quality problems, allowing the improvement actions to be taken at the right time and place. The key advantages of the proposed procedure are: the ability to handle variables and attributes on a single integrated chart, the statistical approach, providing a solid basis for decision making, and the strong managerial appeal provided by the integrated charts.

Abstract

In this chapter, I aim to present a review on the constitution of the sociology of sport as a subfield in Brazil. To do so, I start with the debate over its history, the current status of this academic area and the factors that led to its development. Additionally, I present the main organizations, funding institutions, and the events that support this field. I briefly identify the main postgraduate programs in the country that enable sociological research in sport, mapping their distribution geographically. Next, I present some introductory works of reference on the sociology of sport in Brazil, as well as discussing some authors that were and are key to the field. I highlight the main topics of interest in Brazilian sociology of sport as well as their methodological models and the main theoretical bases of analysis used by late and early career researchers. In conclusion, I evaluate the comprehension and the representation of sport in society and in the academy, pointing to some future perspectives of development and consolidation of the sociology of sport in Brazil.
