Since the 1990s, several policy instruments have been produced in Belo Horizonte, Brazil, to improve accessibility to urban mobility systems, especially for people with disabilities. However, the city still faces important shortcomings in understanding the demands of the population with disabilities and in implementing an appropriate urban structure. The present work identifies mobility practices and demands for accessibility of this population based on a descriptive analysis of the city’s origin/destination survey (2012) and results of a focus group with representatives of the population with disabilities and public authorities. The analysis demonstrates that the demands of persons with reduced mobility are characterised first by a high level of immobility, comparing to people without disabilities, which has important consequences on access to urban goods, especially jobs and health and educational services. Second, mobility has a relevant role in producing forms of discrimination and exclusion. Third, in addition to the problems faced by the general population, people with reduced mobility also face greater challenges in using transport systems. Ultimately, this analysis points out that the main needs for people with disabilities are related to the problems of articulation between public places and transportation systems, both in terms of infrastructure and in terms of attitude and behaviour of service providers and other citizens.

Recently, several areas are successfully applying the Lean Six Sigma methodology, specifically in healthcare, public services, higher education institutions and manufacturing industries. This study aims to present an extensive literature review involving Lean Six Sigma practical applications in the last five years, described in a case studies format.

A systematic literature review was conducted, and 39 articles were selected and analyzed.

An increase in Lean Six Sigma applications in healthcare and higher education institutions was identified. Furthermore, Lean Six Sigma is effectively applied in several areas and is continuously used in traditional industries. The main critical success factor identified was leadership and management involvement, project management and organizational infrastructure, as well as training and education. Also, the main difficulties found are related to the organization's culture and developing communication with leaders and managers.

The main difficulties found in this research are related to the lack of data presented in some articles analyzed, where only information about how the Lean Six Sigma application was conducted is shown, not mentioning difficulties or success factors identified.

Case studies are fundamental to help popularize Lean Six Sigma applications, showing a real-life scenario of how the methodology is implemented, the main difficulties encountered and critical success factors found. Thus, the value of this study is promoting and developing research involving Lean Six Sigma case study applications to guide new researchers and practitioners on the subject.

The objective is to contribute to the development of strategies through the identification of sustainability practices. Thus, the research has a twofold objective: to unveil sustainability practices integrated into last-mile logistics activities by e-commerce retailers, analyze the interrelations among these practices and categorize them based on their significance for small Brazilian e-commerce retailers.

A literature mapping was conducted to identify sustainability practices in last-mile activities adopted by e-retailers, leading to the proposal of a meta-model. A total of 67 articles are part of the final sample. Subsequently, the study applied the Decision-Making Trial and Evaluation Laboratory (DEMATEL) multicriteria decision-making technique to structure the research problem through cause-and-effect analysis among practices, aiming to prioritize critical practices.

The results indicate a strong dependence on economic practices to enable sustainability in last-mile logistics. In the economic dimension of sustainability, operating costs and quality of services are effect variables and achieved the highest relation concerning the other practices.

The article provides theoretical contributions by addressing two complementary areas of knowledge: Stakeholder Theory and Sustainability, also aligning with Global Reporting Initiative (GRI) guidelines. In practical terms, it stands out for offering valuable insights into the implementation of sustainable strategies by identifying economic, environmental and social practices in last-mile logistics, particularly within the context of small businesses in the e-retail segment.

The results help e-retailers re-evaluate last-mile logistics processes from a sustainability perspective. This study aims to fill the knowledge gap in the current literature on adopting sustainable practices in small e-commerce retail firms.

Considering that one of the pillars of sustainability is a commitment to social development, this study contributes to understanding the view of small e-retailers on the independent goods delivery workers responsible for the delivery of goods.

The originality of this research lies in identifying economic, social and environmental sustainability practices adopted by e-retailers in last-mile logistics processes. Additionally, the study focuses on the small-scale e-commerce retail segment, an area that has been little explored in the Brazilian context. Lastly, the proposed meta-model contributes to addressing practices from the perspective of Stakeholder Theory and the Sustainability approach.

El objetivo es contribuir al desarrollo de estrategias mediante la identificación de prácticas sostenibles. Por lo tanto, la investigación tiene un doble objetivo: revelar las prácticas de sostenibilidad integradas en las actividades logísticas de última milla de minoristas de comercio electrónico, analizar las interrelaciones entre estas prácticas y categorizarlas según su importancia para los pequeños minoristas de comercio electrónico en Brasil.

Se llevó a cabo un mapeo de la literatura para identificar prácticas de sostenibilidad en las actividades de última milla adoptadas por minoristas en línea, lo que llevó a la propuesta de un metamodelo. Un total de 67 artículos forman parte de la muestra final. Posteriormente, el estudio aplicó la técnica de toma de decisiones multicriterio Decision-Making Trial and Evaluation Laboratory (DEMATEL) para estructurar el problema de investigación mediante análisis de causa y efecto entre las prácticas, con el objetivo de priorizar las prácticas críticas.

El resultado indica una fuerte dependencia de prácticas económicas para implementar la sostenibilidad en la logística de última milla. En la dimensión económica de la sostenibilidad, los costes operacionales y la calidad de los servicios son variables de efecto y presentan una fuerte correlación.

La originalidad de esta investigación radica en identificar prácticas de sostenibilidad económica, social y ambiental adoptadas por minoristas en línea en los procesos logísticos de última milla. Además, el estudio se centra en el segmento minorista de comercio electrónico a pequeña escala, un área poco explorada en el contexto brasileño. Por último, el metamodelo propuesto contribuye a abordar prácticas desde la perspectiva de la Teoría de los Stakeholders y el enfoque de Sostenibilidad.

El artículo proporciona contribuciones teóricas al abordar dos áreas complementarias de conocimiento: la Teoría de los Stakeholders y la Sostenibilidad, alineándose también con las directrices de la Iniciativa de Reporte Global (GRI). En términos prácticos, destaca al ofrecer ideas valiosas sobre la implementación de estrategias sostenibles al identificar prácticas económicas, ambientales y sociales en la logística de última milla, particularmente en el contexto de las pequeñas empresas en el segmento minorista en línea.

Los resultados ayudan a los minoristas electrónicos a reevaluar los procesos logísticos de última milla desde una perspectiva de sostenibilidad. Este estudio pretende contribuir el avance del conocimiento de la literatura actual sobre la adopción de prácticas sostenibles en pequeñas empresas de comercio electrónico.

Teniendo en cuenta que uno de los pilares de la sostenibilidad es el compromiso con el desarrollo social, este estudio contribuye a comprender la visión de los pequeños minoristas electrónicos sobre los trabajadores independientes encargados de la entrega de mercancías.

The purpose of this paper is to analyze the relation between the values of solidarity economy and the organizational commitment and entrenchment ties.

A quantitative, descriptive and exploratory research was carried out through survey, using the Solidarity Economy Values Scale, Organizational Commitment Questionnaire and Organizational Entrenchment Questionnaire, with statistical data analysis.

The results showed that the self-management, quality of life and identification values positively influenced the workers’ behavior, mainly concerning personal fulfillment with performance and autonomy at work. On the other hand, the citizenship and solidarity values revealed an inverse association with the alternatives limitation dimension of entrenchment: the permanence in solidarity economy organizations motivated solely by the lack of employment can impact negatively on social and political involvement.

Theoretically, organizational commitment and entrenchment ties are not limited to individual behaviors but also have a collective dimension to be investigated.

The workers’ organizational commitment implies in a commitment from the organization with human development through work.

In solidarity economy organizations, the bond based on lack of alternatives on the job market does not affect self-management or fulfillment with the work but the participation on the community politics.

The growing consumer demand for microbiologically safe and quality products with sensory properties similar to those of natural products has spurred the search for natural flavourings with an antimicrobial effect on foods. The purpose of the present study is to evaluate the in vitro antimicrobial activity of “malagueta” chili pepper and “dedo de moça” hot pepper on Minas Frescal cheese supplemented with Escherichia coli strains.

Each cheese contained 0, 10, 15 and 20 per cent concentrations of “malagueta” chilli pepper and “dedo de moça” hot pepper supplemented with 200 µL of E. coli/kg cheese. The cheeses were stored under refrigeration at 7 °C for 28 days. The E. coli, pH and titratable acidity were analysed for this cheese.

“Dedo de moça” hot pepper showed a bacteriostatic effect on E. coli strains being more efficient on day 1. However, the “malagueta” hot pepper showed bactericidal effect and was efficient during the 28 days of storage. The pH showed a gradual decrease (p = 0.000) throughout the storage period; therefore, the acidity was increased even when the CFU/g count remained constant. The peppers had an antimicrobial effect on E. coli strains, and thus might be an alternative to extend the shelf life of Minas frescal cheese.

The study of natural condiments as an antimicrobial alternative is important because they prevent infections and food infections, increase shelf life and make it possible to offer differentiated products in the market.

The purpose of this paper is to develop a performance evaluation model for the operations of the supply chain of an organization of the refrigeration equipment sector. The tool must aid the decision maker in the performance improvement and creation of competitive advantages.

The study adopts a mixture of qualitative and quantitative approaches and applies them through a case study. The data collection was conducted through unstructured interviews and supplemented by documentary research. The applied intervention instrument is the Multicriteria Decision Aid – Constructivist (MCDA-C).

Identification, organization, ordinal and cardinal measurement and integration of the aspects of the context judged as relevant by the decision maker. In addition, it can be highlighted the current situation diagnosis and elaboration of improvement actions related to lean philosophy and advanced planning systems.

The developed model is being used to aid the decision maker in their decisions concerning the improvement of the supply chain operations.

The main contributions made by the paper resides in the proposal of solutions for fulfiling gaps identified within the supply chain performance evaluation area and in the application of the MCDA-C to a practical case.

This study aims to identify different consumer segments to address the strategies that can be adopted by companies and policymakers to increase the consumption of safer foods and reduce the negative externalities caused by pesticides. More than 3,000 consumers were involved in the survey, of which more than 1,000 completed in all parts.

The complexity of the topic required a multidimensional approach. Therefore, the authors modelled the decision support system by proposing a decision rule-based approach to analyse consumers' food purchasing choices. More precisely, the authors referred to the dominance-based rough set approach (DRSA).

Based on the DRSA results, three consumer segments were identified: green consumers, integrated pest management (IPM)-informed and active consumers, and potential low-pesticide consumers for which different policy implications have been highlighted.

Despite the high number of survey respondents, further research should seek to obtain data from a more balanced sample. Furthermore, different methods of analysis could be applied and the results compared.

Identification and promotion of managerial and public policies to increase the consumption of low pesticide food.

The main social implications can be summarised in the greater knowledge and awareness of the environmental aspects related to food, recognition of the intrinsic quality and/or functionality of food.

The authors contribute to the literature in two ways. First, the authors refer to the DRSA, an innovative approach in the context of consumer analysis. Second, based on the decision rules, the authors identify three consumer segments to which specific tools can be addressed.

The purpose of this paper was to build the MACTAK methodology, which aims to transform collective tacit knowledge into the explicit one using knowledge elicitation techniques, associated to quality tools structured by systemography, represent it in a symbolic language and production rules and model it in two expert systems which can assist the investigation of defect causes during the metal packaging production process.

The method applied in the research was classified as exploratory, because a preliminary study was conducted, to better suit the mapping methodology for eliciting collective tacit knowledge, to the reality which was intended to be known. Through studies and the application of the systemography technique, a methodology for the elicitation of collective tacit knowledge has been developed. It suggests a systematic sequence of activities, to map and transform collective tacit knowledge into the explicit one, on the production process which was studied.

The types of tacit knowledge were mapped and became explicit through the application of the methodology proposed. A knowledge management system was created, as such knowledge was validated by other mechanics during their training on the shop-floor, which resulted in a structure of unique and shared knowledge. They became explicit for being stored in a knowledge base and presented to its users through the expert system. It is concluded that the methodology of acquiring collective tacit knowledge helped on the reduction of rework index by standardizing the way used to investigate the cause of the defect, in the studied company.

The MACTAK methodology was developed for exclusive use in industrial processes where the following elements are presented: process, method, environment, raw materials, labor work, measurement and machine. In this method, the detection of the problem occurs from statistical data.

The methodology began in August 2010, and in October 2011, obtained as a result a reduction in rework cost equivalent to US$17,780.95.

The methodology is unique, as it refers to the systematic use of knowledge acquisition techniques and tools of quality, and the methodology has a characteristic of direct application in manufacturing processes. The beneficiaries, in this case, are mechanicals of production and quality inspectors that work at the operation level in the company. For the organizational and tactical level, the beneficiaries are engineers of production.

The purpose of this paper is to characterise eight different fig cultivars with respect to antioxidant activity and bioactive compound content and to assess the influence of these cultivars on the physicochemical characteristics, rheological properties and sensory acceptance of the obtained jelly to identify cultivars with increased potential for processing when grown in subtropical regions.

The analyses of fig fruits and fig jellies were performed in triplicate. To characterise the fig cultivars, analyses of antioxidant activity, phenolic compound content and ascorbic acid concentration were performed on fresh fruits. For the jellies, the total titratable acidity, pH, soluble solids, colour, texture profile and sensory attributes were analysed.

With respect to antioxidant activity and bioactive compounds, the Roxo de Valinhos displayed the highest antioxidant activity according to the ABTS method, ß-carotene and DPPH; the Três num Prato, Lemon and Brunswick cultivars presented the highest ascorbic acid values; and the Três num Prato cultivar also had the highest total phenolic content. Generally, the various fig cultivars yielded jellies with different physical and chemical characteristics and different rheological properties. This variation did not significantly affect acceptability. This study demonstrates that all of the evaluated cultivars have high potential for processing.

This study evaluated the processing potential of Roxo de Valinhos and other fig cultivars in the form of jelly, which in view of the food risk concerns of the dried fig, seems to be an interesting alternative for consumption of processed fig.
