ABSTRACT

Although net-zero greenhouse gas emission targets continue to gather burgeoning streams of research, there is a lacuna in current literature on the pathway challenges towards operationalizing decarbonization. The study advanced 2 × 2 matrix of an organizing framework of challenges in accomplishing net-zero emissions targets. Using the global airline industry as an illustrative context, the study provided deep insights on the pivotal industry, institutional, and organizational challenges in the era of COVID-19 such as fleet modernization, over-reliance on fossil fuel, slow progress in the development of hydrogen and electric aircraft, risk of corporate greenwashing, and divergent approaches adopted by airlines. The challenges can be classified into policy-oriented, organization-specific, and external/macro-environment factors. The contributions to theory and practices were identified and examined.

ABSTRACT

As a result of the COVID-19 pandemic, supply chains (SCs) have been exposed to their greatest disruption in recent memory. This unprecedented situation has given rise to the concept of SC survivability, which is based on the need to find a new temporary equilibrium allowing SCs to survive during extreme events. The purpose of this paper is to contribute to the conceptualization of SC survivability by providing some basic foundations for this new concept. Our analysis shows that dealing with SC survivability requires a larger scale than those adopted for the analysis of SC resilience. To solve this issue, we propose a new framework called "Human Needs Supply chains". This framework shows the interdependencies between SCs, society, and the environment and enables a shift from the classical SC's product-profit view to a holistic view centred on the satisfaction of basic human needs. Another contribution of this research is to highlight the links between SC survivability, SC resilience, and SC sustainability. We show that the classical resilience capacities (i.e., absorptive, adaptive, and restorative) are not enough to deal with extraordinary and long-term disruptions such as COVID-19, and we propose an adaptation of the SC resilience concept to integrate a survivability capacity. Building resilience with a survivability capacity will allow SCs to stay alive in a temporary non-viable equilibrium of sustainability during a large disruption and to recover to a viable equilibrium at the end of the crisis.

ABSTRACT

COVID-19 has generated the largest disruption of the present century, forcing mankind to evaluate many paradigms. Educators have faced the challenge to develop teaching strategies suitable for distance learning, which is particularly complex for those engineering concepts where service learning is an effective approach. This paper presents a remote service based learning strategy, used to teach seismic vulnerability assessment to fourth-year Civil Engineering students at Universidad de La Sabana in Colombia. This strategy involved five stages and was adapted to be carried out remotely by students in their homes using a combination of several tools such as remote maps. The main activities were the seismic vulnerability assessment of the students' houses and the remote assessment of the building stock of Cajica & PRIME;, a municipality close to the University campus. The learning outcomes were assessed using evaluation rubrics. The results show that the proposed strategy is effective, as 100% of students scored at the top level of the rubric at the fifth stage. In addition, they indicate that service learning in a close context like the family generates motivation and commitment in students to their learning process. Overall, this experience demonstrated that service learning is an effective strategy for teaching engineering concepts in a remote environment. It also showed that although COVID-19 required the development of new teaching strategies, this did not become a limitation to fulfill the learning outcomes.

ABSTRACT

Waste management is a key feature to ensure sustainable consumption and production patterns, and to combat the impacts of climate change. In this scenario, the production of biochar from different biomasses results in environmental and economic advantages. In this study, biochar was produced from sugarcane bagasse pyrolysis, to immobilize biomolecules, in order to assemble an electrochemical immunosensor to detect antibodies against SARS-CoV-2. For this, screen-printed carbon electrodes (SPCE) were modified with a dispersion of biochar and used to immobilize the receptor-binding-domain (RBD) against virus S-protein, through EDC/NHS crosslinking reaction. Under the best set of experimental conditions, negative and positive serum samples responses distinguished based on a cutoff value of 82.3 %, at a 95 % confidence level. The immunosensor showed selective behavior to antibodies against yellow fever and its performance was stable up to 7 days of storage. Therefore, biochar yielded from sugarcane bagasse is an ecofriendly material that can be used as a platform to immobilize biomolecules for construction of electrochemical biosensors.

ABSTRACT

The development of evidence-based interventions (EBIs) for the prevention of behavioral health problems is well supported. However, limited data exist on the sustainability of EBIs once initial support has ceased. The current study assessed, at 2 years after initial start-up support: (1) What percent of schools sustained EBI implementation? (2) To what degree did sustaining schools implement the EBI with fidelity? (3) What were the primary reasons for not sustaining the EBI? (4) What theoretical and contextual factors during initial start-up support predicted sustainment of the EBI? The study used process evaluation data from the dissemination of the Botvin LifeSkills Training (LST) middle school program in 158 school districts (including 419 schools). Fifty-one percent of districts sustained the EBI and most of these sustaining districts reported following key fidelity guidelines. Primary reasons for discontinuing centered around low teacher or administrative support and turnover. Significant predictors of sustaining LST were higher ratings of LST's complexity, benefit, and compatibility by teachers; more positive perceptions of organizational support from administrators; and smaller proportions of Black students. Results show that EBI sustainment and fidelity of implementation post-initial startup support are feasible, though likely not for all schools. Findings also suggest that cultivating support for the EBI among staff during start-up support may be helpful for sustainment and that social determinants of a school have a complex relationship with EBI sustainment. Future research should explore true causes of differences due to race/ethnicity as well as COVID-19 effects.

ABSTRACT

The widespread outbreak of a new Coronavirus (COVID-19) strain has reminded the world of the destructive effects of pandemic and epidemic diseases. Pandemic outbreaks such as COVID-19 are considered a type of risk to supply chains (SCs) affecting SC performance. Healthcare SC performance can be assessed using advanced Management Science (MS) and Operations Research (OR) approaches to improve the efficiency of existing healthcare systems when confronted by pandemic outbreaks such as COVID-19 and Influenza. This paper intends to develop a novel network range directional measure (RDM) approach for evaluating the sustainability and resilience of healthcare SCs in response to the COVID-19 pandemic outbreak. First, we propose a non-radial network RDM method in the presence of negative data. Then, the model is extended to deal with the different types of data such as ratio, integer, undesirable, and zero in efficiency measurement of sustainable and resilient healthcare SCs. To mitigate conditions of uncertainty in performance evaluation results, we use chance-constrained programming (CCP) for the developed model. The proposed approach suggests how to improve the efficiency of healthcare SCs. We present a case study, along with managerial implications, demonstrating the applicability and usefulness of the proposed model. The results show how well our proposed model can assess the sustainability and resilience of healthcare supply chains in the presence of dissimilar types of data and how, under different conditions, the efficiency of decision-making units (DMUs) changes.

ABSTRACT

In recent years, it became clear that the human unsustainable behaviours’ impact on the environment. Environment protected behavior is especially relevant in the context of the current epidemiological situation ushered by the COVID-19. Environmental awareness is becoming a part of everyday life. The time has come when it is necessary to sacrifice the comfort for the future of the planet. This study primarily focuses on the attitudes of residents of a typical Russian industrial city towards environmental issues and the use of the Energy-Saving Behavior Index (ESBI) as an environmental indicator of sustainable behavior. Our work investigates ESBI and the factors which are associated with domestic energy-saving behavior. We surveyed 599 people in Chelyabinsk, Russia. We studied (1) the socio-demographic factors of residents and their households, (2) mental health and subjective well-being (SWB), and (3) physical health. The study showed that the overwhelming majority of residents of a typical Russian city are extremely dissatisfied with the state of the environment (more than 80% of respondents) and 70% of them believe that they can contribute to improving the situation. However, Russians are still wasteful in household energy consumption. It has been shown that unstable behavior is due to psychological factors and has a compensatory mechanism that is connected with the “feelings-emotions-behavior” sequence.

ABSTRACT

There is a rapid increase in energy demand across several developing economies all over the world. This can be attributed to population growth, industrialization, urbanization, globalization, and occasional unforeseen events such as the COVID-19 pandemic, in which operations, functions, and activities are mostly executed virtually. With a major transition to renewables by developed economies to meet their energy obligations and mitigate greenhouse gas (GHG) emissions, developing economies are left with no choice but to join the transition in a bid to uphold the United Nations’ Sustainable Development Goal 13 (SDG13-Climate Action). This study has identified and prioritized barriers to renewable energy transition in developing economies. The Hybrid Structural Interaction Matrix (HSIM) was utilized to employ the weight based prioritization model with hierarchical structural layout of the interacting renewable energy transition barriers. This study will be of great benefit to policymakers and academics in making informed decisions on measures to fast-track the transition to renewables in developing economies by considering weighted prioritized driving forces for optimum resource allocation.

ABSTRACT

Learning outcomes: This case study aims to yield the following learning outcomes: understand the key performance indicators of successful human resource management (HRM) in the hospitality and tourism sector, especially during pandemics;identify the various concepts and strategies of HRM and recruitment over a short period;conceptualize the types of HRM practices such as safety and health, recruitment and promotion and rewards when facing pandemic conditions as well as the handling of hotel staff in strained times;evaluate the crisis management solutions used by human resources to lower the employee turnover rate;and develop a crisis management plan from a human resource standpoint in a pandemic situation. Case overview/synopsis: A five-star hotel in Abu Dhabi, United Arab Emirates (UAE), Bab Al Qasr Hotel & Residence (BAQHotel) opened in October 2016. In April 2020, the hotel began accepting patients with COVID-19 in conjunction with the Abu Dhabi’s Healthcare Company (SEHA), as a support to the UAE Government, through Department of Culture and Tourism Abu Dhabi (DCTAD), to meet the local needs and sustain business during these unforeseen circumstances, which heavily impacted the whole World. Samer Majari, the Human Resource Director of BAQ hotel was responsible for recruiting and supervising delegates, while ensuring the comfort of hotel staff, arranging for their transportation, catering, safety and well-being. To combat the high staff turnover, including COVID-19-positive staff, Majari reviewed the existing staff model;divided the staff into two groups for providing services to both sides of the hotel;arranged for separate accommodations, food and transportation;and retained the existing resources and recruited new workers. This study aims to provide management solutions that concern hiring of staff from the existing UAE market and highlights ways of creating a lower staff turnover rate through incentives and compensations, while also managing staff by motivating them and also safeguarding them against COVID-19. Complexity academic level: This case study intends to provide a context for creative solutions to human resource challenges facing organizations during a pandemic. It also involves swift responses to crises faced by HR managers and the immediate solutions required. Therefore, this case study can be used in undergraduate level courses for students pursuing a bachelor’s or a master’s degree in HRM, hospitality management, crisis management or international business studies.

ABSTRACT

The coronavirus(COVID-19)pandemic disruption adversely impacted the Supply Chain for Natural Gas(NG) retailing, jeopardizing committed targets for thesocio-economic transition toa gas-based economyleading to inclusive growth in India. Furthermore, Omicron'srapid spread is a cause of global concern. This research aims to develop a conceptual Supply Chain Performance (SCP) measurement methodology for reducing recovery time post exogenous disruption. Exploratory research involving an integrative literature review identifies different approaches, frameworks, models, and techniques for Supply Chain PerformanceMeasurement(SCPM). Analysis reveals that the application of DMAIC improves the reliability of Supply Chain Management (SCM) functional processes during disruption recovery while synthesizing the Balanced Scorecard (BSC) with Triple Bottom Line(TBL) accounting approach provides a rigorous robust method to represents financial, social, and environmental performance goals. Accordingly, findings present a methodology with nine systematic steps to evaluate performance by City Gas Distribution(CGD)entities to accelerate NG retail consumption and speed up network expansion to meetthe growing clean energy demand of the urban populace. Additionally, anIndian model for transition to a gas-based economy is also presentedto distinguish competing goals to harmonize growth with environmental sustainability and ecological modernization. Though SCP is a mature concept, the literature on its methodology during disruption recovery for NG retailing is scanty. Hence, the proposed action-oriented SCPM methodology has practical implications for improving SCP, contributing uniquely to the retail SCM domain for NG. Its application will instigate industry practitioners to review Supply Chain Management (SCM) processes and strategies to improve service effectiveness and delivery efficiency.

ABSTRACT

South Africa, a country considered affluent in nature, ranks third in global biodiversity and encompasses approximately 9% of higher plants on planet Earth. Many indigenous plants have been utilised as herbal medicine, proving successful in treating numerous ailments. From the common cold to pandemic maladies such as COVID-19 in the 21st century and the treatment of incurable diseases, South African inhabitants have found great promise in the healing properties of these plants. Phytomedicine is a rapidly evolving topic, with in-depth bioactive composition analysis, identifying therapeutic action mechanisms, and disease prevention. While we are now poised to take advantage of nature's medicine cabinet with greater scientific vigour, it remains critical that these practises are done with caution. Overharvesting significantly impacts biodiversity and cultivation practices amidst the beautiful nature of these nutraceuticals. This book chapter focuses on the therapeutic potential of commonly used South African medicinal plants, their ethnopharmacological properties, and how we can conserve this treasure cove we call home for future generations.

ABSTRACT

Purpose - This paper aims to investigate the effect of firms sustainability practices on firm performance and valuation during the COVLD-19 pandemic. Design/methodology/approach - Using a sample of Australian listed firms from 2011 to 2021, the authors perform textual analysis on sustainability practices from annual reports and sustainability report disclosures and include this variable in various regression models that assess firm valuation. The authors also use propensity score matching and Heckman two-stage regression methodology to address endogeneity concerns. Findings - The authors find that flints disclosing sustainability practices exhibit higher market valuations relative to other firms. Specifically, lass-making fins exhibit higher market valuation during the COVID-19 crisis relative to prior period. The authors also observe a negative association between sustainability practices and firm performance proxied by return on assets. The findings suggest that engagement in sustainable practices helps loss-making firms remain resilient during the pandemic In addition, the authors find that the positive relation between sustainability practices and firm value is stronger among firms with a higher level of annual report readability. Originality/value - Considering the conflicting evidence in the literature on the economic benefits of sustainability practices, this study takes advantage of the heterogeneity in corporate practices and provides empirical evidence that a firm's sustainability practices can build economic resilience during the COVID-19 pandemic crisis. The authors believe the findings of the study is timely in informing the regulators and standard-setters on changes in reporting required to increase sustainability in the business practices.

ABSTRACT

Purpose Due to increasing uncertainty in the global business scenario, research on supply chain resilience is gaining significance. The outbreak of the COVID-19 pandemic has accelerated and magnified the issues already pertaining in the supply chain thereby increasing the vulnerabilities in the network. This study attempts to build the concept of pseudo-resilience in supplier selection and evaluation for supply chain sustainability. Design/methodology/approach A combination of multi-criteria decision-making methods AHP and R is adopted, and an integrated method called Combined AHP-R method is used to identify and include the property of pseudo-resilience into supplier selection processes. Findings The authors identified various factors contributing to pseudo-resilience considering supplier selection process and found the most important attribute. Using the combined AHP-R method, the suppliers were evaluated, considering the attributes contributing to the pseudo-resilience of supply chains and best supplier was selected. Originality/value To the best of our knowledge, this is the first study addressing a supplier selection problem for sustainable supply chains, considering pseudo-resilience. Also, this is the first study to apply the AHP-R method for supplier selection in the resilience or sustainability context.

ABSTRACT

Purpose One of the most important components of healthcare is the timely delivery of pharmaceutical products, such as life-saving medicines. However, disruptions like COVID-19 bring new challenges and risks to the pharmaceutical supply chain (PSC) and healthcare organizations that impact their operational performance. This study focuses on mitigating risks in India's generic medicine supply chain (GMSC) as a result of various disruptions, which can assist policymakers develop appropriate plans and strategies to build resilience in the Jan Aushadhi Scheme (JAS) of micro, small and medium enterprises (MSMEs) in order to improve their overall performance. Design/methodology/approach Risk-causing vulnerabilities and resilience capabilities are identified from the literature review and expert's opinions. Following that, the vulnerabilities are classified into cause-and-effect vulnerabilities, and supply chain resilient capabilities (SCRCs) are measured using a hybrid fuzzy DEMATEL and best worst method (FDEMATEL-BMW) framework. Findings The outcome of the study reveals that transportation breakdown, loss of human resources and loss of suppliers are the potential risk-causing vulnerabilities that lead to vulnerabilities like shortages of medicines, loss of in-hand stock qualities and loss of sales/revenue. In addition, the analysis suggests that the sustainability of an organization with maximum weightage is the critical factor for building resilience in GMSC followed by flexibility, agility and visibility. Practical implications The integration of resilience into Jan Aushadhi GMSC can help in managing disruptions efficiently and effectively to mitigate risk and optimize MSMEs overall performance. Originality/value To the best of the authors' knowledge, this work will be the first of its kind to model resilience in GMSC of MSMEs using a hybrid framework.

ABSTRACT

These are constantly changing times for the tourism industry. The COVID-19 pandemic and accompanying negative economic effects significantly impacted customer behavior and accelerated the need for companies to innovate. Business model innovation (BMI) is ideal for overcome these challenges by innovating the very core of the firm. However, siloed BMI thinking is insufficient: firms need a more holistic approach. We expand the current understanding of business model innovation by proposing a framework that integrates relevant dimensions (change impulses and business model configurations), context factors (service newness and degree of change or destination characteristics), and the outcomes of BMI initiatives into a comprehensive model for the tourism industry context. With our work, we want to guide future research and expand the currently unbalanced, heterogeneous picture of BMI in service industries.

ABSTRACT

The global supply chain experienced unprecedented disruption due to the Covid-19 crisis in a dynamic world. Consequently, this situation has resulted in many businesses' discontinuity or closure due to disruptions that seriously affect the possibility of maintaining operations, especially micro, small and medium-sized enterprises (MSMEs) in emerging markets. In this scenario, the food value chain is deeply concerned because of its vulnerability and importance to food security. Therefore, this study aims to examine the mechanism that enables businesses in the food value chain to overcome the challenging post-pandemic while rebuilding the foundation for long-term viability and sustainable development. Accordingly, this study examines the relationships between the responsible driving factors (towards the environment, society, and the economy) and the food value chain sustainability (FSCS) of MSMEs by exploiting the mediating role of sustainable supply chain management (SSCM) in an emerging market. This study applies a quantitative research approach using primary data from a questionnaire-based survey. 568 valid responses were received from managers at senior and middle levels. In analysis, this study uses a smart PLS 3.3.2 version, Structural Equation Modeling (SEM) technique, to analyze the structural relationships. The novelty of this study contributes beyond the extant body of knowledge of supply chain management (SCM) by providing a comprehensive approach to promoting FSCS by incorporating socially, environmentally, and economically responsible practices into SCM practices. In addition, this study contributes to broadening the concept of corporate social responsibility by broadening the perspective of sustainability by shifting the enterprise-based perspective to the food value chain-based perspective. Above all, this research provides a new approach to the food value chain in an emerging market that is inherently too challenging to afford the sustainability concept of the food value chain. In sum, the value of this study's contribution is significant to bridging the knowledge-practice gap by providing profound knowledge and an empirically proven framework for the mechanism boosting sustainability for MSMEs in the food value chain in emerging economies. Drawn upon the above highlights, the findings of this study may be of high interest to academics, business practitioners, and policy-makers.

ABSTRACT

Intense tourism is a common occurrence in environments with very attractive natural traits and that host important ecosystem services, such as islands and coastal environments. However, these activities can cause impacts and loss of ecosystem services, thus requiring assessments about tourism activities and how to manage their complexity. Thus, the objective of the present study was to carry out an environmental impact assessment based on ecosystems in two islands with strong tourist pressure in the state of Santa Catarina, Brazil. The islands analyzed were Anhatomirim and Campeche, and the methodology used was the ecosystem-based Survey of Environmental Aspects and Impacts (SEAI), carried out by means of structured technical visits following a bibliographic analysis of the study area. Results indicated that the analysis model constructed can contribute to decision-making in environmental management, as it enabled a clear and objective identification of the main aspects, environmental impacts, and ecosystem services that are somehow connected. Among the negative impacts observed, the most relevant were water pollution, impaired health of wild animals, loss of biodiversity, and the spread of Covid-19. In turn, the most prominent positive impact was the generation of employment and income. The demand for environmental education projects in the tourist system that involves the two islands is also highlighted. Thus, this investigation was shown to be useful for the identification of the main anthropic elements derived from tourism that affect these ecosystems.

ABSTRACT

Antitrust law is at the center of today's public debate. It has even emerged as a rare unifying force, with bipartisan promises to combat the concentration of economic power. Meanwhile, the business community is grappling with mounting systematic risks arising from climate change, income inequality, and the COVID-19 pandemic. Unexpectedly, the largest asset managers in the world find themselves on the front lines of these battles. Due to the rise of index investing, these "universal owners" manage portfolios that are so large and diversified, their holdings mirror the entire economy. Their diversification protects them against idiosyncratic risk, but greatly exposes them to systematic risks. The universal owners are keenly aware of their exposure to these risks. They are turning to their portfolio companies and increasing demands on directors and managers to "serve a social purpose" and reduce their negative externalities. Public-regarding pronouncements from CEOs of Wall Street's biggest firms ring hollow to many shareholder primacy loyalists. But the skeptics downplay the economic logic underlying this paradigm shift-cliversified shareholders do not want companies to externalize their negative impacts onto the rest of the investors' portfolios. Many companies are rising to the challenge and making bold commitments. Some are recognizing that, to overcome pervasive social and environmental challenges, they must collaborate with their competitors. This Article reveals that current antitrust law is a barrier to this collaboration and offers a policy proposal for aligning antitrust law with the demands upon the prosocial corporation. The COVID-19 pandemic has reminded us that we are all interconnected. Climate change will continue to deepen that understanding. The problems we face are difficult, but they are not insurmountable. To solve them, however, antitrust law must empower more collaboration.

ABSTRACT

Sustainable investing has gained significant momentum over the past few years. In this paper, we study the performance and flows of sustainable equity mutual funds in recent years through the COVID-19 pandemic. We find that the high-sustainable funds perform better than the low-sustainable ones by between 1.32% and 6.96% annually. This outperformance significantly increases during the COVID-19 pandemic-induced market crash and the post-crash pandemic. Similarly, we find that high-sustainable funds attract significantly more investments (or suffer less outflow) than the low-sustainable funds by between 5.28% and 5.76% per annum. These flow differences increase considerably during the market crash, consistent with the 'flight-to-quality' effect. We also find that the high-sustainable funds attract significantly more investment during the post-crash pandemic than before the crash. This suggests that investors consider sustainable investing a necessity (not a luxury good), and their taste/attitude towards sustainable investing has changed - now they prioritize 'investing with a conscience.'

ABSTRACT

Stringent lockdowns have been one of the defining features of the COVID-19 pandemic. Lockdowns have brought about drastic changes in living styles, including increased residential occupancy and telework practices predicted to last long. The variation in occupancy pattern and energy use needs to be assessed at the household level. Consequently, the new occupancy times will impact the performance of energy efficiency measures. To address these gaps, this work uses a real case study, a two-story residential building in the Okanagan Valley (British Columbia, Canada). Further, steady-state building energy simulations are performed on the HOT2000 tool to evaluate the resiliency of energy efficiency measures under a full lockdown. Three-year monitored energy data is analyzed to study the implications of COVID-19 lockdowns on HVAC and non-HVAC loads at a monthly temporal scale. The results show a marked change in energy use patterns and a higher increase in May 2020 compared to the previous two years. Calibrated energy models built on HOT2000 are then used to study the impacts of pre-COVID-19 (old normal occupancy) and post-COVID-19 (new normal occupancy) on energy upgrades performance. The simulations show that under higher occupancy times, the annual electricity use increased by 16.4%, while natural gas use decreased by 7.6%. The results indicate that overall residential buildings following pre-COVID-19 occupancy schedules had higher energy-saving potential than those with new normal occupancy. In addition, the variation in occupancy and stakeholder preferences directly impact the ranking of energy efficiency measures. Furthermore, this study identifies energy efficiency measures that provide flexibility for the decision-makers by identifying low-cost options feasible under a range of occupancy schedules.
