Supply chain management literature provides several frameworks aiming to identify the constructs of supply chain performance and supply chain resilience. Nevertheless, the literature lacks a framework that encompasses healthcare supply chains and its idiosyncrasies. Therefore, the purpose of this paper is to propose a framework for analysing the relationships between the antecedent factors, mediators, and consequents of healthcare supply chain resilience (HCSCRes). The supply chain risk management (SCRM) literature shows a significant gap concerning a framework that comprises the particularities of SCRM applied to healthcare. In this sense, based on the importance of identifying the determinants of HCSCRes, qualitative, and exploratory research was developed through an extensive literature review. In this sense, we propose two research questions: (i) Which are the antecedents, mediators, consequents of a resilient Healthcare Supply Chain? (ii) Which are the variables that compose the constructs of a resilient healthcare supply chain? The proposed framework of this research was designed to analyse healthcare organisations, including the healthcare supply chain. To use the proposed framework in other industries (e.g. commerce, services), it is necessary to make adaptations and adjustments on the observable variables and constructs. The main contributions of the paper are twofold: (i) Show an essential theoretical value in proposing scales for the HCSCRes factors and can be useful for future quantitative approach and surveys. (ii) The literature review reveals that the set of practices and technologies known as industry 4.0 plays a major role in the theoretical framework proposed by this paper.

Purpose: This paper aims to present a systematic literature review (SLR) to investigate how supply chain risk management (SCRM) is applied to the healthcare supply chains and which improvement opportunities are being missed in this segment.Design/methodology/approach: This SLR used the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) method to answer three research questions: (1) Which are the main gaps concerning healthcare supply chain risk management (HCSCRM)? (2) What is the definition of HCSCRM? and (3) What are the risk management techniques and approaches used in healthcare supply chains?Findings: The authors present a complete summary of the HCSCRM body of research, investigating research strings like clinical engineering and high reliability organizations (HROs) and its relations with HCSCRM; (1) This research revealed the five pillars of HCSCRM; (2) The authors proposed a formal definition for HCSCRM considering all the literature blocks explored and (3) The authors generated a list of risks present in healthcare supply chains resulting from extensive article research.Research limitations/implications: The authors only reviewed international journal articles (published in the English language), excluding conference papers, dissertations and theses, textbooks, book chapters, unpublished articles and notes. In addition, the study did not thoroughly investigate specific countries' particularities concerning how the healthcare providers are organized.Originality/value: The contribution of this article is threefold: (1) To the best of authors knowledge, there is no other SLR about HCSCRM published in the scientific literature by the time of realization of authors’ work, suggesting that is the first effort to fulfill this research gap; (2) Following the previous contribution, in this work the authors propose a first formal definition for HCSCRM and (3) The authors analyzed concepts such as clinical engineering and HROs to establish the building blocks of HCSCRM.

One hundred soil samples were collected from urban spaces, in Lisbon, Portugal, in two surveys that were carried out in consecutive years, to assess the potential adverse human health effects following exposure to potentially toxic elements and organic compounds in the urban soils. The study hereby described follows on from the earlier work of the authors and aims at performing a source-pathway-fate analysis of lead (Pb) and polycyclic aromatic hydrocarbons (PAHs) in the urban soils in order to increase current knowledge on factors influencing exposure of the population. Various techniques were combined to achieve the proposed goal. Geogenic and anthropogenic sources were apportioned by means of Pb isotope mixing models. Isotope data was further coupled with geographic information system mapping to assess local mixed sources of Pb and PAHs. Unleaded vehicle exhaust and cement production show the largest relative contribution to the total soil-Pb, but their respective importance depends on factors such as location and urban landscape. The primary sources of PAHs to the urban soils are probably air and land traffic. Multivariate analysis was used to investigate which soil properties could influence mobility and fate of the contaminants. Whilst principal components analysis indicates carbonates and other calcium phases as probable factors controlling the dispersion of Pb in the urban soils, the linear models obtained from stepwise multiple regression analysis show that soil phosphorous (P) and manganese (Mn) are good predictors of the total soil Pb content. No robust model was obtained for the PAHs, impeding identifying environmental factors most likely to influence their dispersion in the urban soils. The solid-phase distribution study provided critical information to untangle the, at a first glance, contradictory results obtained by the multivariate analysis. Carbonates and other calcium phases, having these a probable anthropogenic origin, are soil components containing major fractions of Pb, P, and Mn.

The COVID-19 pandemic has promoted a big change in the educational sector. Suddenly, teachers, professors, and students had to migrate from presential classes to the online system without prior notice or a training course. This paper aimed to verify how the need of a rapid change to the online system in response to the impossibility of keeping the presential system due to the mandatory social distancing imposed by the COVID-19 pandemic has affected relationships and performance of teachers, professors, and students, as well as review the technologies and procedures adopted by them to innovate and achieve sustainable education. To address the empirical side of this exploratory research, the authors of this paper sent an email questionnaire to kindergarten, elementary and high school teachers in the City of Rio de Janeiro (Brazil), as well as to professors of the top 197 Brazilian universities. To address theoretical side of this exploratory research, an investigation was carried out through scientific databases. The data were analyzed with SPSS (Statistical Package for the Social Sciences), version 22.0, and with Microsoft Excel 2007. As a result, this paper showed that social isolation and transition to the online system greatly affected the work conditions of teachers and professors, as well as the learning process of students. Anyway, sustainable actions were taken to overcome these challenges. Furthermore, this paper proposed a framework that might support the development of new studies, filling the literature gap on the subject.

The aim of this exploratory research is to identify how working from home and the consequent social isolation interfered in teachers’ work and students’ learning and to identify the challenges, difficulties, advantages, opportunities, demands, trends, implications, outlooks, lessons, directions, and feelings of students and teachers in the teaching processes during the COVID-19 pandemic period. To reach its aim, the authors of this paper developed searches and scientific databases and they also sent an email questionnaire to Rio de Janeiro city schools. The descriptive analyses were made by descriptive statistics (proportions, rates, minimum, maximum, mean, median, standard deviation, coefficient of variation—CV). The results show that working from home and the consequent social isolation interfered in the students’ and teachers’ feelings and sensations and highlight the words “frustration”, “hope”, and “strangeness”. From the sample, 96.4% of the teachers affirmed that working from home and the social isolation interfered in their work and 97.4% of the teachers affirmed that working from home and the consequent social isolation interfered in the students’ learning. This research is the starting point to boost discussions on the subjects of COVID-19, working from home, social isolation, and education. This paper will support researchers in the development of future studies related to the subjects.

The healthcare environment aims at improving and quality in health management, with trends and practices in hospitals, institutions, clinics, laboratories and companies in this segment, with the purpose of bringing more comfort and better conditions in the care of patients. Faced with the difficulties of this area, it becomes increasingly important to reduce waste and improve processes. The goal of this paper is to carry out a systematic review of literature on the topic lean manufacturing in healthcare. The data were obtained from four online databases Web of Science, Science Direct, Emerald Insight and Scopus. Articles indexed in the last 10 years were selected (2006-2016). To select articles, an advanced search was performed using the Boolean expression "E" that combined keywords for better specific results. Professionals working in the health segment will have the concepts and applied techniques, in addition to the work indexed in recent years, which will facilitate the research and development of the work, translating into increased efficiency and ultimately, improvement for the population. Despite the importance of the theme, there are few lean manufacturing jobs applied in the healthcare environment. This research can stimulate future studies due to its applicability for the improvement of health services.
