These results provide valuable insights for developing effective risk management strategies to mitigate cargo robbery risks in the e-commerce sector. The study contributes to the literature on cargo security in last-mile delivery and offers practical implications for businesses, logistics professionals, and policymakers involved in the Brazilian e-commerce industry.
Artigo 5 Citação(ões) na Scopus Electronic collaboration in supply chain management: a study of manufacturing companies in Brazil(2016-01-05) Claudia Mattos; LAURINDO, F. J. B.Electronic collaboration emerges as a differentiating element in supply chain management. This new operational method makes it necessary to understand which concepts are related to the collaborative context, which tools are used and what their impact on performance is, so that managers can direct their management chain decisions. The broad aim of this study is to examine the application of collaborative tools in the supply chain, and to check if managers identify performance improvements in the group of companies that apply these tools. The methodology is based on literature review and quantitative method, using the cluster analysis statistical technique. The results indicate that the group of companies with more significant collaborative features has a different perception of performance, when compared to other groups with lower level of collaborative tools implementation.- Trials of strength, paradoxes and competing networks in kaizen institutionalization(2023-05-04) CARNEIRO, W. N.; OYADOMARI, J. C. T.; AFONSO, P.; Dultra-de-Lima, R. G.; MENDONÇA NETO, O. R. DE© 2023, Emerald Publishing Limited.Purpose: This paper seeks to understand kaizen in practice as it travels through time and space in the organisational setting. Design/methodology/approach: A qualitative case study was carried out at a multinational company using mainly interviews for the data collection that were analysed from an actor-network theory (ANT) perspective. Findings: This paper finds that the company deals with a series of paradoxes while managing the kaizen process. Efficiency and quality paradoxes are the basis for starting kaizen projects. Furthermore, intrinsic, and extrinsic motivation, emerge in these processes, and paradoxes relate to how spontaneous ideas emerge in a deliberated context of cost-saving objectives. The supply chain finance team coordinates kaizen projects with the collaboration of plant managers, promoting the paradox of autonomy and control. In addition, as kaizen mobilises and enrols the actors, some trials of strength emerge, showing actors who oppose the kaizen network and create competing networks that mutually exist in the firm. Practical implications: This study presents valuable insights for professionals to successfully implement kaizen methodologies that take advantage of developing a network for problem-solving in organizations. Originality/value: This study highlights the supply chain finance team's role in enrolling the actors within a network built by practitioners engaged in kaizen projects. Usually, engineers, quality, or manufacturing teams lead kaizen projects, and only occasionally, accounting and financial teams participate, including multidisciplinary teams.
- Uniaxial plastic strain effect on the corrosion-fatigue resistance of ISO 5832-1 stainless steel biomaterial(2023) NAVILLE, W.; Rodrigo Magnabosco; COSTA, I.© 2023 Elsevier LtdOrthopaedic implants are used for fracture stabilization or orthopaedic reconstruction. During implantation and even in the implant accommodation process, there may be plastic strain and induction of residual stresses. This information creates a test procedure involving pre-strain, pre-conditioning in the corrosive environment and corrosion-fatigue tests. Two solutions were used, PBS (phosphate-buffered saline, neutral pH, recommended for corrosion evaluation tests) and SHA (saline solution with hydrogen peroxide and albumin pH 3.0). The results showed that, differently from PBS, SHA promoted localized corrosion, reducing fatigue resistance in all tested conditions. In addition, plastic pre-strain influenced the failure process.
- Relationships among strategically aligned performance indicators, controls, and performance(2023-01-05) OYADOMARI, J. C. T.; BIDO, D. S.; MENDONÇA NETO, O. R. M.; AGUIAR, A. B.; Ronaldo Gomes Dutra-de-Lima© 2023 Universidade de Sao Paulo. All rights reserved.This paper investigates if planning and cost controls and strategically aligned performance indicators (SAPI) are necessary and sufficient conditions to achieve a high level of organizational performance (OP). This article fills a gap in research by investigating elements of the management control system as necessary and sufficient conditions to achieve high levels of OP. Our findings show the reduced importance of planning controls and the great importance of aligning priorities and indicators to achieve high levels of performance. The paper is helpful for the practitioners that have to choose what kind of management controls are priorities to achieve high levels of performance. Management control frameworks are helpful for the literature and the practice. Still, the practitioners cannot implement the whole set of these components, considering the restriction of time and contingency aspects. The companies must choose what kind of management controls they have to implement, considering the goal of achieving performance. We used a quantitative methodology based on contingency theory in a survey of 89 Brazilian firms. The relationships were tested using partial least squares structural equations modeling (PLS-SEM), and necessary condition analysis (NCA) was applied to identify the management controls that are sufficient and necessary conditions for superior performance. The results of our study suggest that a high level of strategically aligned indicators is necessary to achieve a high level of performance. Results also suggest the importance of aligning strategic priorities with appropriated performance indicators, primarily defended in the normative (balanced scorecard) and empirical literature.
- Analysis of IoT adoption for vegetable crop cultivation: Multiple case studies(2023) Scur G.; da Silva A.V.D.; Mattos C.A.; Goncalves R.F.© 2023 Elsevier Inc.This study aims to fill a gap in the literature regarding the interrelationship between agricultural modernization and the internet of things (IoT), particularly in vegetable crop cultivation. Therefore, it focuses on understanding the barriers to and enablers of IoT adoption in planting and harvesting vegetables. We built a theoretical framework that incorporates the constructs of individual and organizational technology adoption models, linking behavioral, technological, organizational, and environmental factors. The framework is supported by the technology-organization-environment (TOE) and unified theory of acceptance and use of technology (UTAUT) models. We conducted in-depth interviews with 15 producers, three agricultural sector experts, and four suppliers. The results showed that only established producers implemented technology, indicating that organizational factors are decisive for the adoption of the IoT. Thus, the producer's size, knowledge, management level, and investment power affect IoT adoption. The theoretical model needs to be assessed according to producers' size, thereby revealing that organizational factors directly influence producers' behavioral issues.
- Exploring the readiness of a Brazilian technological university during the COVID-19 pandemic(2023-01-05) Gabriela Scur; Alliprandini D.H.; Chinaglia E.F.; Roberto Santos© 2022, Emerald Publishing Limited.Purpose: The paper investigates the learning practices carried out by Higher Education Institutions (HEIs) in the transition from strictly face-to-face to remote teaching in response to the coronavirus disease 2019 (COVID-19) pandemic. It also analyses how these practices could be used as a baseline to support new perspectives on learning in the technological education field. Design/methodology/approach: The authors conducted a single-case study of a Brazilian technological university. Findings: This study’s findings indicate that institutional planning and providing support to faculty and students were essential measures for a successful transition from face-to-face teaching to emergency remote teaching. Planning includes careful selection by the HEI of the tools that make a virtual learning environment and the strategies used to replace face-to-face teaching with emergency remote teaching. Our study points out the lessons learned during the pandemic. It presents guidelines for HEIs on how to prepare for a return to face-to-face teaching, embodying some learning dimensions such as synchronous or asynchronous, active or passive, individual or collective, and mediated or not mediated by information and communication technologies (ICTs). Originality/value: The paper provides reflections on the four dimensions to support decisions to leverage learning in each educational institution. This paper's main contribution is that the concept of teaching and learning must be comprehensive and inclusive according to the particular HEI context.
- Development of a Digital Twin for smart farming: Irrigation management system for water saving(2023-02-15) ALVES, R. G.; MAIA, R. F.; Fabio Lima© 2023 Elsevier LtdWorld agriculture faces the challenge of increasing its agricultural production by 50 % from 2012 to 2050, while reducing water consumption, as agriculture accounts for 69 % of all fresh water used on the planet. The use of technologies such as the internet of things, artificial intelligence, digital twins, among others, in the agricultural environment is increasing. Digital twin applied to agriculture is in its early stages of development. A digital twin is one in which data flows automatically and in both directions between a physical object and a virtual object. Withing this context, this paper presents a digital twin of a smart irrigation system in an application scenario. A digital twin for an irrigation system is one in which the physical components of the system, such as its sensors and actuators, are connected with their virtual representations. The system is composed of a FIWARE-based internet of things platform and a discrete event simulation model in Siemens Plant Simulation software. The internet of things platform is used to collect, aggregate and process soil, weather and crop data to calculate daily irrigation prescriptions. The simulation model is used to simulate the behavior of an irrigation system defined in an application scenario. The communication between the platform and the simulation model happens in real-time and is intermediate by an OPC UA server. A application scenario is considered to evaluate the behavior of the system and to evaluate, in future research, different irrigation strategies. The benefits of the systems proposed are twofold. First, evaluate the behavior of the Internet of Things (IoT) platform and an irrigation system before implementing both in the field. Second, enable the evaluation of different irrigation strategies in parallel with current farm practices. Within the system proposed, farmers can evaluate the behavior of the system before implementing in their farms and allowing the system to operate automatically. It is possible to infer that the system can improve farm operations and reduce water usage by allowing farmers to gather soil, weather and crop information and evaluate multiple irrigation strategies.
- How absorptive capacity influences project performance(2022-11-29) Ronaldo Gomes Dultra-de-Lima; BRITO, L. A. L.© 2022, Emerald Publishing Limited.Purpose: The absorptive capacity (AC) leads to firm performance and influences the development and evolution of capabilities and routines, but the influence of AC in projects remains unclear. Therefore, this study aims to investigate the effect of AC on project performance (PP) in the construction industry of Sao Paulo State, Brazil. Design/methodology/approach: The authors conducted a survey questionnaire with project managers and collected 157 responses in the construction sector. They also used confirmatory factor analysis (CFA) and multiple linear regression techniques to assess the data. Findings: The study provides empirical evidence that realized absorptive capacity (RAC) has a direct and indirect positive effect on PP. Conversely, the potential absorptive capacity (PAC) only indirectly impacts PP through project management practices (PMPs). PAC and RAC positively influence PMPs that in turn positively influence PP. The findings reinforce the relevance of AC to the development of internal knowledge for processes and routines, thereby enhancing PP. Practical implications: The findings provide practical implications: the AC influences PP by refining and adapting routines. Moreover, the consistent application of accepted practices is not enough for PP, but the ability to adapt, adjust and transform the relevant knowledge into routines. Originality/value: This paper provides empirical evidence that the knowledge application of PMPs improves organizational performance through PP. However, despite what the literature has discussed, this paper proved that AC has no effect as a moderating factor between PMPs and performance; however, AC's role significantly impacts PP through PMPs.
- The role of Industry 4.0 in developing resilience for manufacturing companies during COVID-19(2023-02-05) Débora Bianco; BUENO, A.; GODINHO FILHO, M.; LATAN, H.; GANGA, G. M. D.; FRANK, A. G.; JABBOUR, C. J. C.© 2022 Elsevier B.V.Humanity has faced many crises in the past, such as pandemics, wars, and economic crises, and other crises are certain to come in the future; however, emerging technologies have a role to play in improving companies’ resilience in the face of such crises. The coronavirus (COVID-19) pandemic has led to human, technological, and managerial constraints for manufacturing companies due to scarce resources or supply chain (SC) disruptions. The research goal of this paper is to investigate whether Industry 4.0 implementation improved companies’ resilience and whether companies’ performance maintained stability during the COVID-19 outbreak. Composite-based structural equation modeling is applied to analyse data collected from 207 manufacturing companies. The theoretical model is grounded in the Practice-Based View (PBV) theory. The research findings show that operational responses based on Industry 4.0, smart manufacturing practices, and smart capabilities enable manufacturers to build resilience and quickly mitigate performance loss in times of global crisis. Therefore, the results demonstrate that Industry 4.0 implementation provides resilience for companies through flexibility, reliability, robustness, and responsiveness. The main practical implication of this study is to support managers in achieving manufacturing performance stability during disrupted times, such as the COVID-19 crisis, using Industry 4.0 approaches to make their companies more resilient and prepared to face future challenges and crises.
