FACTORS SHAPING DINER'S COVID-19 PREVENTIVE BEHAVIOR: A CASE STUDY IN THE UNITED ARAB EMIRATES

This research attempts to understand how individuals prevent themselves from exposure to COVID-19 when dining out at a restaurant and what situational factors shaping their COVID-19 preventive behavior (CPB) are. It collects 303 questionnaires responded by restaurant patrons in the United Arab Emirates. The resultant data reveals the ranks of the relative importance among the five CPBs proposed by this study that wearing a mask is considered the most critical CPB. In contrast, wearing gloves is the least desirable CPB. Concerning five health-risk factors under investigation, there is no difference in CPB between the vaccinated and non-vaccinated. People suffering from issues with their immune system show a significant inclination to stress social distancing compared to those without any immune issues. Those having an inflected family member are apt to wear gloves. Further, individuals bearing risk factors concerning chronic illness, an immune problem, and an infected family member are inclined to wash their hands and wear gloves. Lastly, this research finds six situational factors affecting an individual's CPB. © 2023 Thouraya Gherissi Labben, Joseph S. Chen and Hyangmi Kim.

Lung re-transplantation for COVID-19 related respiratory failure: A case report

Objectives: We would like to report a case in which a COVID-19 patient who was transferred to our hospital due to a lack of medical resources due to the COVID-19 outbreak in Daegu, South Korea, on February, 2020, underwent double lung transplantation after 110 days with VV-ECMO support and performed double lung re-transplantation 865 days after lung transplantation. Method(s): ECMO was performed on a total of 69 patients with COVID-19-related acute circulatory/ respiratory failure from February 2020 to December 2022. Among them, 16 patients were registered for lung transplantation, and 5 out of 16 registered patients performed lung transplants. One in five people who performed lung transplantation performed retransplantation on the 865thday after transplantation. Result(s): A 52-year-old female patient was transferred to our hospital, and VV-ECMO was performed the next day. The double lung transplantation was performed 112 days after hospitalization and was discharged 238 days after surgery. 668 days after lung transplantation, home O2 was applied as bronchitis obliterans syndrome, and her lung function deteriorated rapidly later, and re-transplantation was decided. In the patient;s HLA test, HLA class I cPRA% was 32% and HLA class II cPRA% was 100%. Desensitization was performed six times plasmapheresis with administrating Botezomib and immunoglobulin, and then re-transplantation was performed on the 865th day after lung transplantation. The patient has maintained her daily life without any special complications other than the occurrence of central DI after surgery. The pathological findings of the lung previously transplanted to the patient were acute rejection (ISHLT grade A2), chronic airway rejection (ISHLT grade C1, B0), and chronic vascular rejection (ISHLT grade D1). Conclusion(s): The long term result of patients who performed lung transplantation with COVID 19 related respiratory failure is still unknown. Therefore, even patients who have undergone long-term VV-ECMO support due to COVID 19 related respiratory failure are expected to achieve good results if lung transplantation is needed by carefully approaching and treating with a multidisciplinary approach.

Sensitivity Analysis of Medical Waste Sterilization Shredder Using Surrogate Model

Medical waste has been excessively generated in various medical facilities due to COVID-19, and its treatment has become an important concern. Previously, an optimized medical waste sterilization and shredding system was developed for hospital scale but due to increased demand, it is necessary to scale such a system for different facilities. Therefore, in this paper, a sensitivity analysis for the design variables of the shredding system has been conducted and a surrogate model is developed for stress estimation. The surrogate model was generated using LHS (Latin hypercube sampling), which can represent the overall information of the design domain with a limited number of samples. The surrogate model was then used to increase the number of samples for sensitivity analysis which helped in reducing the computational time for finite element analysis. The sensitive variables for the shredder system were then estimated using sensitivity analysis. Consequently, an efficient design framework for various capacities of medical waste shredder was suggested using sensitivity analysis and a data-driven surrogate model.

Using humor to increase COVID-19 vaccination intention for the unvaccinated: The moderating role of trust in government

Since COVID-19 was declared a global pandemic, scholars and practitioners have put much effort into testing effective advertising strategies for COVID-19 vaccinations. Guided by humor theories, this study aimed to examine (1) the effect of humor on persuading COVID-19 vaccination and (2) the moderating role of trust in government for the unvaccinated population. Across two studies (college students and general adult populations), for lower trust in government individuals, through greater public service advertisement (PSA) processing depth and believability, there was a higher vaccination intention after the humor (non-humor) advertisement. For higher trust in government individuals, there was evidence that the vaccination intention was lowered after the humor (vs. non-humor) message through lowered PSA processing depth and believability. This study expands humor theory into testing COVID-19 vaccination messages while considering an individual psychological factor, trust in the government, that has emerged as an essential determinant to COVID-19 messaging. The contributions to COVID-19 vaccination advertising strategy and advertising to the unvaccinated population, in general, are discussed.

Risk factors for delirium among patients with advanced cancer in palliative care: a multicenter, patient-based registry cohort in South Korea

OBJECTIVE: Previous studies have comprehensively investigated the preva-lence and various potential risk factors for de-lirium among patients with advanced cancer ad-mitted to the acute palliative care unit (APCU). Our objective was to evaluate the comprehen-sive association between delirium and various risk factors among patients with advanced can-cer in an acute palliative care setting using a pa-tient-based multicenter registry cohort.PATIENTS AND METHODS: We performed a multicenter, patient-based registry cohort study collected in South Korea between January 1, 2019, and December 31, 2020. Delirium was identified using a medical record review based on the criteria of the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition.RESULTS: In total, 2,124 eligible patients with advanced cancer in the APCU met the inclu-sion criteria. There were 127 out of 2,124 pa-tients (prevalence, 6.0%;95% CI, 5.0 to 7.1) with delirium during admission. Delirium in patients with advanced cancer was associated with age >70 years (OR, 1.793;95% CI, 1.246 to 2.581), male sex (OR, 1.675;95% CI, 1.131 to 2.479), no chemotherapy during hospitalization (OR, 2.019;95% CI, 1.236 to 3.298), hearing impairment (OR, 3.566;95% CI, 1.176 to 10.810), underweight (OR, 1.826;95% CI, 1.067 to 3.124), current use of opioid medication (OR, 1.942;95% CI, 1.264 to 2.982), previous history of delirium (OR, 12.497;95% CI, 6.920 to 22.568), and mental illness (OR, 2.333;95% CI, 1.251 to 4.352).CONCLUSIONS: In a large-scale multicenter patient-based registry cohort, delirium was asso-ciated with old age, male sex, no chemotherapy during hospitalization, hearing impairment, un-derweight, current use of opioid medication, and a history of delirium and mental illness. Our find-ings suggest physicians should pay attention to delirium in patients with advanced cancer admit-ted to the APCU with the above risk factors.

Hemoglobin-Based Oxygen Carriers: Brief History, Pharmacology and Design Strategies, Review of the Major Products in Clinical Trials, On-Going Studies, and Coagulation Concerns

Transfusion of erythrocytes (RBC) to treat acute or chronic anemia has significant drawbacks, given the risks of transfusion, volunteer donor requirements, limited supply with increasing demand, especially during a pandemic such as COVID-19, and erythrocytes are often unavailable in emergency situations or where blood is not an option. Significant research has been undertaken for almost 100 years to attempt to replicate the functions of RBCs with oxygen carriers/oxygen therapeutics based on hemoglobin. Oxygen carriers that have been evaluated are hemoglobin-based oxygen carriers (HBOCs). HBOCs utilize hemoglobin (Hb) to transport oxygen around the body. Blood transfusion may be critical therapy in hemorrhagic trauma, various pathologies both acute and chronic, and surgical interventions. It has some important goals: the first and most important is to recover oxygen delivery to organs, additionally, when restoration of circulating blood volume is achieved, maintenance of adequate blood pressure to ensure enough blood flow to deliver the oxygen to the microcirculation and resolving oxygen debt. This chapter will review the history of HBOCs, discuss how HBOCs have been designed and how developed HBOCs differ from each other based on their pharmacology and physiology, highlight all major products to undergo human trials including one extensively studied product approved for human use in two countries (Hemopure), introduce newer products still under development, and finally present translational and clinical trials studying whether or not certain HBOCs may cause coagulation issues. © The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Switzerland AG 2022.

Performance of Indicators Used in the Regular Risk Assessment for Covid-19

Intro: Since November 2021, gradual changes in non-pharmaceutical interventions (NPI) had begun in consideration of the socio-economic cost and the high rate of COVID-19 vaccination. As an effort to monitor the COVID-19 situation and the effect of NPIs, regular risk assessment for COVID-19 has been conducted based on the input from the external advisory committee. This paper examines the correlation between the risk assessment results and other indicators, such as the incidence of COVID-19, public perception, community mobility, and the government policy from November 2021 to May 2022. Method(s): For weekly regular risk assessment of COVID-19, the data were collected from the National Infectious Disease Surveillance System website, which included incidence, mortality, and % of severe cases. Other indicators were from regular surveys on perceived risk among the public, community mobility from the Google website, and the government's response policy from The Oxford Stringency Index. The level of risk was classified into five levels from very low to very high. The level of COVID-19 risk and its correlation with the COVID-19 incidence, risk perception, community mobility, and government policy were examined. Finding(s): The result of the correlation analysis showed the highest positive correlation between the risk level and risk perception (r=0.86, CI 0.72-0.94). This indicates that the actual risk level and the risk perceived by the public are similar. Among the incidence-related indicators, the number of new severe cases of COVID-19 per week showed the highest correlation with the risk level (r=0.62, CI 0.33-0.80). Conclusion(s): The high correlation between the weekly severe cases and the overall COVID-19 risk level suggests that Korea's COVID-19 policy priority was mainly at protecting the high-risk populationCopyright © 2023

Phase 3 Study of Safety and Immunogenicity of Gbp510 Vaccine Adjuvanted with As03 in Adults

Intro: GBP510 contains the self-assembling recombinant nanoparticle displaying SARS-CoV-2 Spike protein receptor binding domain and is adjuvanted with AS03. We report interim Phase 3 study (NCT05007951) results up to 4 weeks post-dose 2 (Data-cut: March-18-2022), where immunogenicity to the D614G ancestral strain and safety of 25mug GBP510/AS03 candidate was compared to ChAdOx1-S (Vaxzevria). Method(s): This Phase 3 randomized, active-controlled, observer-blind, parallel- group study in adults was conducted in 6 countries. Cohort1: 1,895 subjects (naive to COVID-19 vaccination and infection) randomized at 2:1 ratio (GBP510/AS03:ChAdOx1-S) to assess immunogenicity and safety;Cohort 2: 2,141 subjects at 5:1 ratio, regardless of their serostatus at screening for safety assessment. Subjects were vaccinated twice at a 4-week interval with 0.5 mL of the test vaccine (GBP510/AS03) or active control (ChAdOx1-S) in deltoid muscle. The primary objective was to demonstrate the superiority of geometric mean titer (GMT) and non-inferiority in seroconversion rate (SCR: >=4-fold rise from baseline) of neutralizing antibodies over ChAdOx1-S by live-virus neutralization assay (FRNT). Finding(s): At 2 weeks post-dose 2, GMT ratio of the two groups (Test vaccine/Active control) was 2.93 [95% CI: 2.63, 3.27], satisfying the hypothesis of superiority (95% CI lower limit> 1). The SCR difference (Test vaccine - Active control) was 10.76% [95% CI: 7.68, 14.32], satisfying the hypothesis of non- inferiority (95% CI lower limit> -5%). Good cell-mediated immune responses for Th1 cytokines were also observed with the test vaccine (FluoroSpot). The AE incidence rate for the test vaccine was higher than the active control for solicited local AEs (56.69% vs 49.20%), and comparable for solicited systemic AEs (51.21% vs 53.51%) and unsolicited AEs (13.34% vs 14.66%) after any vaccination. Conclusion(s): Higher immune responses were observed with GBP510/AS03 compared to ChAdOx1-S against D614G strain after 2 weeks post-dose 2. GBP510/AS03 showed a clinically acceptable safety profile;no safety concerns were identified during the study period.Copyright © 2023

Cryopreservation of Unrelated Donor Stem Cell Grafts Is Associated with Lower Rates of Chronic Gvhd after Allogeneic Transplantation

Allogeneic hematopoietic stem cell transplantation (allo- HSCT) has traditionally involves administering fresh peripheral blood or bone marrow stem cells. At onset of the COVID-19 pandemic in March 2020, the National Marrow Donor Program (NDMP) mandated cryopreservation of all unrelated peripheral blood stem cell (PBSC) products to prevent interruptions in transplant plans by donor COVID-19 infection after recipient's start of conditioning chemotherapy. Since the lifting of this mandate, many centers have continued to cryopreserve grafts prior to initiation of conditioning, but the longer-term clinical outcomes of this practice including chronic graft versus host disease (cGVHD) rates of patients receiving cryopreserved stem cells have not been previously well described. Prior work has raised concern for a deleterious effect of cryopreservation on overall survival and non-relapse mortality (PMID: 33865804). However, heterogeneity in the patient population and reason for cryopreservation suggest that further study is needed to assess these outcomes. Here we report our single-institution experience of clinical outcomes using cryopreserved versus fresh URD PBSCs for allo-HSCT. We examined long-term outcomes in 387 patients who received unrelated donor (URD) PBSCs (136 cryopreserved, 251 fresh) between January 1, 2019 and July 31, 2021. The cohorts had similar baseline characteristics including donor/recipient age/sex, disease, conditioning regimen/intensity, and GVHD prophylaxis regimens. Two-year OS, PFS, relapse, NRM, and acute GVHD rates were not different between recipients of fresh versus cryopreserved PBSCs. Strikingly, 2-year incidence of cGVHD (28% vs 52%, p=0.00001) and moderate/severe cGVHD (9% vs 24%, p=0.00016) was substantially lower in recipients of cryopreserved PBSCs compared to fresh, respectively (Figure 1). This difference was only noted in patients receiving a GVHD prophylaxis regimen without post-transplantation cyclophosphamide (PTCY) (no PTCY 2-year cGVHD incidence cryopreserved vs fresh: 29% vs 57%, p=0.000016), moderate/severe cGVHD 16% vs 34%, p=0.0006) (Figure 2). For patients receiving a PTCY-containing GVHD prophylaxis regimen, there was no difference in cGVHD incidence (cGVHD cryopreserved vs fresh: 24% vs 27%, p=0.56, moderate/severe cGVHD 7% vs 9.3%, p=0.3, Figure 3). (Figure Presented) (Figure Presented) (Figure Presented) While survival and relapse rates are not different, cryopreservation is associated with a marked reduction in cGVHD rates in the setting of non-PTCy based GVHD prophylaxis. Larger multicenter or registry analyses are needed to confirm these observations and may prompt a re-assessment of the role of cryopreservation of stem cell products in clinical practice. If confirmed, it will be critical to understand the immunologic consequences of cryopreservation and how they might influence the clinical impact on chronic GVHDCopyright © 2023 American Society for Transplantation and Cellular Therapy

SURVEY ON VENTILATION, INDOOR ENVIRONMENT, AND MEASUREMENT AGAINST COVID-19 IN CLUBS AND BARS (PART 1): OVERVIEW OF BUILDING FACILITIES, VENTILATION CONDITION AND INFECTION STATUS

From the early stages of the COVID-19 outbreak, there have been many reports on cluster infections in clubs and bars. Meanwhile, there is no report on the indoor air environment in those places and it will limit measures for infection control. This study aims to understand the indoor air and ventilation environment and to propose practical and appropriate improvement measures for related industries. In addition to measuring CO2 concentration in clubs and bars in Tokyo, we have surveyed the voluntary measures taken against COVID-19, outlines of building and ventilation/air conditioning equipment, ventilation regime, and so on. © 2023 Architectural Institute of Japan.

Retrospective Assessment of the Accuracy of Mpox Case Projections in New York City

Background: In mid-2022, New York City (NYC) became the epicenter of the US mpox epidemic. Health authorities were in need of forecasts to anticipate the timing and magnitude of the outbreak. We provided mathematical modelbased projections with methodologies that evolved alongside the epidemic. Here, we retrospectively evaluate our mpox case projections and reflect on potential reasons for accuracies and inaccuracies. Method(s): Early in the outbreak (July 1 - 15, 2022), when the size of the at-risk population was unknown, we performed short-term (2-week) forecasting using exponential regression. Once epidemic growth was no longer exponential (July 15 - Aug. 9), we consulted with the NYC Department of Health and Mental Hygiene regarding populations most-at-risk of mpox based on available epidemiological data. Modelers and epidemiologists collaboratively developed an estimate of 70,180 people at risk, informed by estimates of LGBTQ adults with male sex at birth who had 2+ partners in the last 3 months. We combined this with NYC case count data, NYC vaccination data, and global mpox natural history data to develop a Susceptible-Exposed-Infected-Recovered (SEIR) model, taking into account immunity accrued through vaccination and prior exposure, for longer-term forecasting. Result(s): Initial exponential forecasts of the NYC mpox outbreak were only accurate for very short-term predictions (< 2 weeks) (Figure, top panel). Forecasts were more accurate after 1 week (mean absolute error: 83.0 cases/ wk) than after 2 weeks (mean absolute error: 351.4 cases/wk). In contrast, the SEIR model accurately predicted the decline in cases through the end of Sept. 2022, when cases fell to < 70/wk. Over the period from Aug. 10 to Sept. 24 2022, the mean absolute error of the SEIR-based projection was 8.2 cases per week (Figure, bottom panel). Conclusion(s): Model-based NYC mpox projections provided only short-term accuracy in the early epidemic, but long-term accuracy once the epidemic exited exponential growth and an SEIR model was developed. Cumulative cases and vaccinations when exiting exponential growth, and the epidemiology of those most-at-risk, provided evidence for the likely size of the most-at-risk population - a crucial input for an accurate SEIR model. The ability of the SEIR model to accurately forecast mpox cases was in part attributable to lack of vaccine or immune escape by mpox, in contrast to more rapidly-evolving viruses such as SARS-CoV-2.

Healthcare response strategies for the long-COVID era

Background: Coronavirus disease (COVID-19), first reported at the end of 2019, is characterized by a broad spectrum of clinical manifestations ranging from asymptomatic to multi-organ dysfunction. These symptoms may persist even after the acute phase has passed. Post-acute COVID-19 syndrome (long-COVID) is a condition characterized by COVID-19 symptoms that persist for longer than two months after infection. Fatigue, muscle and joint pain, dyspnea, cognitive impairment, and anxiety are the most common symptoms of long-COVID. Given the substantial impact of COVID-19 sequelae on the quality of life of its survivors, as well as its socioeconomic burden, proactive measures are required. Current Concepts: Following the identification of long-COVID characteristics and symptoms, patient-centered care based on vaccination, COVID-19 medications, and digital healthcare is recommended. Furthermore, people who are more vulnerable to long-COVID, such as those with respiratory dysfunctions or the older adults, require more specialized and attentive management. Big data and artificial intelligence will hopefully enable a more Discussion and Conclusion: Infectious diseases threaten our lives constantly, as evidenced by the recent COVID-19 pandemic and its lingering consequences. A novel virus can emerge at any time and place, resulting in substantial clinical and economic loss. At this stage, it is crucial to establish prompt and effective strategies against long-COVID, as well as against potential pandemics.

Improving Global Supply Chain Risk Identification Using Rcf

This paper contains an introduction to industrial problems, solutions, and results conducted with the Korea Association of Machinery Industry. The client company commis-sioned the problem of upgrading the method of identifying global supply risky items. Accord-ingly, the factors affecting the supply and demand of imported items in the global supply chain were identified and the method of selecting risky items was studied and delivered. Through research and discussions with the client companies, it is confirmed that the most suitable fac-tors for identifying global supply risky items are 'import size', 'import dependence', and 'trend abnormality'. The meaning of each indicator is introduced, and risky items are selected us-ing export/import data until October 2022. Through this paper, it is expected that countries and companies will be able to identify global supply risky items in advance and prepare for risks in the new normal situation: the economic situation caused by infectious diseases such as the COVID-19 pandemic;and the export/import regulation due to geopolitical problems. The client company will include in his report, the method presented in this paper and the risky items selected by the method.

Epidemiology, risk factors, and prevention of colorectal cancer

Background: Colorectal cancer remains the fourth most common malignancy in Korea, and has been ranked as the third leading cause of cancer deaths in 2020. This study aims to describe the epidemiologic status of colorectal cancer in Korea, and provide basic data for effective primary and secondary prevention methods by summarizing risk factors and screening tools. Current Concepts: Although colorectal cancer incidence and mortality have decreased in recent years in Korea, it still poses a significant public health burden. From the early 1990s until the mid-2000s, the 5-year relative survival of patients with colorectal cancer in Korea continuously increased. This can be attributed to the successful introduction of the government-led screening program;development of improved surgical techniques, anticancer drugs, and adjuvant treatment;and advances medical resources and infrastructure along with economic growth. However, since the late 2000s, the improvement in survival has stagnated. The coronavirus disease 2019 outbreak has reduced hospital visits and screenings, which is assumed to cause delays in diagnosis, leading to a worse prognosis in the patients. To overcome these obstacles, it is essential to explore modifiable environmental risk factors and appropriate screening test methods in Korea. Discussion and Conclusion: Primary prevention through risk factor modification and secondary prevention using suitable screening programs can reduce the incidence and mortality rates of colorectal cancer.

A Zero-Knowledge-Range-Proof-based Privacy-Preserving Blockchain Platform for COVID-19 Contact Tracing

Contact tracing is an effective strategy to slow down the COVID-19 pandemic. However, the use of digital footprints as supportive evidences in the contact tracing process rises the privacy problems since private information must be shared to the contact tracing providers. This paper proposed a novel privacypreserving contact tracing procedure based on zero-knowledgerange-proof and blockchain platform, which helps users to prove whether they in contact with the confirmed patient without disclosing the exact location they have visited. The blockchain is used to guarantee anonymity through the use of address as an identity, and provide strong non-repudiation from transactions. Finally, we provide a proof-of-concept implementation of our proposal using Hyperledger Fabric and smartphone application. The evaluation showed that the proposed system can work as intended with minimal processing delay.

The impacts of demand and supply shocks in the dry bulk shipping market

The freight rate is a representative variable in the shipping market and is characterized by a cyclical re-lationship. Even though downturns in the shipping market, such as the shipping industry recession in the 1980s, the global financial crisis in 2008 and COVID-19 crisis in 2020, recur, few studies have analyzed the dynamic relationship between supply and demand in terms of its effect on freight rates. Thus, this study classifies the factors affecting fluctuations in dry cargo freight rates into demand, supply, and freight rate specific demand factors, which play the most important role in managing risk in the shipping market. Based on the recursive structural vector autoregressive (recursive SVAR) model, we analyze the historical con-tributions of the effects of each factor across different time periods. Two main findings are summarized as follows: first, we identify the dynamic relationship between factors affecting BDI in the shipping market, and reveal that the magnitude and direction of factors are different. Second, we verify that in an extreme situation in which freight rates exceed the normal range, the market is overheated, and freight rates are therefore determined by the freight rate specific demand of market participants rather than by the actual supply and demand.(c) 2023 The Authors.

Measuring the impacts of quantity and trustworthiness of information on COVID-19 vaccination intent

The COVID-19 crisis provided an opportunity for information professionals to rethink the role of information in individuals' decision making such as vaccine uptake. Unlike previous studies, which often considered information as a single factor among others, this study examined the impact of the quantity and trustworthiness of information on people's adoption of information for vaccination decisions based on the information adoption model. We analyzed COVID-19 Preventive Behavior Survey data collected by the Massachusetts Institute of Technology from Facebook users (N = 82,213) in 15 countries between October 2020 and March 2021. The results of logistic regression analyses indicate that reasonable quantity and trustworthiness of information were positively related to COVID-19 vaccination intent. But excessive and less than the desired amount of information was more likely to have negative impacts on vaccination intent. The degrees of trust in the mediums and in the sources were associated with the level of vaccine acceptance. But the effects of trustworthiness accorded to information sources showed variations across sources and mediums. Implications for information professionals and suggestions for policies are discussed. © 2023 Association for Information Science and Technology.

Effective environmental education for sustainable development beyond the Plastic Age in South Korea

The skyrocketing single-plastic demand during the coronavirus disease 2019 (COVID-19) pandemic proved the limitation of top-down environmental policies in accomplishing sustainable consumption and waste management. Nevertheless, ‘smart consumers' can make smart choices for sustainable development. However, a review of the South Korean environmental education curriculum reveals that the current structure heavily leans towards the elementary level and does not enlighten the public on ‘what' and ‘how' to live sustainably. This study uses a quick survey to suggest that the effectiveness of environmental education may be enhanced if: (1) guidance on how to live with the natural environment in harmony for collective cooperation towards resilient and sustainable community building is incorporated with a clear purpose, (2) environment-friendly culture-building activities are enforced to institutionalise a new paradigm of sustainability to replace today's consumerism, and (3) contents are updated regularly to include Earth and environmental science knowledge in the state of art. © 2023 Informa UK Limited, trading as Taylor & Francis Group.

Impact of movie-watching on cross-selling revenue in shopping malls: Implications for post-pandemic recovery

The COVID-19 pandemic has prompted consumers to postpone in-store purchases and shift to online shopping, decreasing overall retail spending. As the global lockdown eases and shoppers return to offline stores and malls, shopping malls seek to facilitate in-store consumer experiences at entertainment facilities. Given the importance of entertainment facilities to the cross-selling revenue of shopping malls, we investigate the relationship between consumers' movie-watching and subsequent (hedonistic) grocery purchases. Our analysis of a panel database that includes transaction details at the consumer level shows that movie-watching is negatively correlated with consumer spending. Furthermore, consumers' psychological states induced by content and contextual factors moderate the negative effect of movie-watching;after watching a fantasy (as compared to thriller) genre or watching a movie in a less crowded theater, consumers are more likely to make hedonic purchases at the supermarket. These findings provide theoretical and managerial implications for retail operators exploring cross-selling opportunities post-pandemic. © 2023
