External shocks such as the COVID-19 pandemic can fundamentally change the working conditions of salespeople and their customer interactions. This paper examines whether and how a change in social media usage by B2B salespeople following the first wave of lockdowns in response to COVID-19 in 2020 affected their sales performance. The results of a survey of 568 B2B salespeople show that an increase in social media usage following this external shock can lead to an increase in salespeople's performance under certain conditions: This effect is contingent on the salespeople's level of training in social media and their customer focus in social media usage. If these conditions are not met, an increase in social media usage following this external shock may even decrease salespeople's performance. These findings provide insights into how firms can better understand what helps to be prepared for a crisis such as the COVID-19 pandemic and successfully further embed social media in the functioning of their sales organizations.

Background: There is limited evidence on the priorities and opportunities associated with promoting population physical activity (PA) participation for the post-COVID-19-pandemic future. Purpose: This study assessed government-led PA promotion efforts before and during the COVID-19 pandemic, along with post-COVID-19-pandemic priorities and recommendations. Methods: Two separate cross-sectional surveys conducted in 2023. Survey 1 was targeted at the Global Observatory for Physical Activity (GoPA!) Country Contacts. Survey 2 also included key international informants representing influential stakeholders in PA policy implementation. Results: There were 68 respondents to Survey 1, collectively representing 61 countries. An additional 37 people, including representatives from 14 key international stakeholders responded to Survey 2. Eighty-two percent of countries had national PA policies. COVID-19 widely disrupted PA policy implementation. Less than 40% of countries integrated PA into their COVID-19 response plan and more than 75% reported policies that restricted PA participation. Although most respondents indicated that government PA priorities did not change due to the COVID-19 pandemic, one in five countries reported that cross-sectoral partnership had become more important during this period. Less than a third of postpandemic governments reported as highly engaged despite the widespread proliferation of PA policies and plans prior to the pandemic. There were variations according to country, region, and income. Conclusions: Elevating PA promotion on the public health agenda is crucial for the post-COVID-19-pandemic era. At a policy level, it is critical to focus on adequate resourcing, cross-sectoral partnerships, integrated interventions, and inequities in participation. These factors have become increasingly important in the postpandemic PA policy landscape. [ABSTRACT FROM AUTHOR]

Supply chain resilience is on the agenda of academia and industry like never before. One strong instigator for this phenomenon has been the COVID-19 pandemic, which opened the era of global uncertainties and vulnerabilities. In this paper, we analyse the transformation of supply chain resilience research through the COVID-19 pandemic. Methodologically, we use a hybrid approach based on a combination of elements of a bibliometric and expert analysis to compare the main topics of resilience research before, during, and after the pandemic. Along with an expected observation about an exponential growth of literature on supply chain resilience in and after 2020, we observe a major shift from preparedness and disruption predictions in the pre-pandemic literature towards recovery and proactive adaptation in the pandemic and post-pandemic research. Our analysis systematically reveals some new topics, management practices, and future research areas in supply chain resilience. In particular, digital technology, supply chain viability, the cross-industry ripple effect, and intertwined networks have become new and impactful research areas during the COVID-19 pandemic. Further developments of these topics are expected to be continued in future. Managerial and theoretical implications of the said developments conclude this paper. [ABSTRACT FROM AUTHOR]

This study contributes to the academic discourse on the evolution of virtual qualitative enquiries in the wake of the accelerated adoption of digital technology following the COVID-19 pandemic. Employing a critical-reflection approach, this study explored the experiences of investigators who conducted 150 soft laddering interviews, either online or face-to-face. The research provides a theoretical reflection on online soft laddering and its application with new technological tools, such as video conferencing and social media, demonstrating how these tools mitigate logistical and relational limitations while enhancing data collection scope and reach. The findings indicate that technological advancements are fostering a gradual hybridisation of digital and physical methods, particularly those utilising synchronous interviews. As the physical and digital realms converge, this trend leads to the phygitalisation of qualitative research. [ABSTRACT FROM AUTHOR]

Background: Latinos in the United States face multiple barriers to engaging in physical activity (PA). We implemented a faith-based multilevel intervention to promote PA in parks for Latino adults, which was partially adapted to a virtual platform during the COVID-19 pandemic, and evaluated it using the Reach, Effectiveness, Adoption, Implementation, and Maintenance framework. Methods: We conducted in-depth semistructured interviews (83% in Spanish) with 24 intervention participants (75% women) participating in a cluster randomized controlled trial in 2019–2022 that linked 6 churches (3 intervention, 3 control) with parks in East Los Angeles, CA. The intervention included in-person, park-based fitness classes, which were adapted to Facebook during the pandemic; PA motivational text messages; and other activities. Interviews assessed Reach (participation), Effectiveness (perceived impacts), Implementation (participation barriers/facilitators), and Maintenance (plans for sustaining PA), as well as perceived pandemic impacts. Results: About 80% of interviewees participated in ≥1 park class and 67% in ≥1 virtual class (Reach). Interviewees perceived positive intervention impacts across multiple health and well-being domains (Effectiveness) despite perceived negative pandemic impacts; several facilitators to participation (personal, social, program) and few barriers (personal, virtual, environmental; Implementation); and plans for maintaining PA (eg, revisiting intervention text messages and video recordings; Maintenance). Conclusions: Findings support the utility of Reach, Effectiveness, Adoption, Implementation, and Maintenance to understand the broad impacts of a faith-based PA intervention. Findings point to the adaptability and robustness of the intervention during a public health crisis. Overall, findings may help inform the translation of the intervention to other communities to advance health equity. [ABSTRACT FROM AUTHOR]

Background: This prospective observation study explored the association between 24-hour movement behaviors and fundamental movement skills (FMS) in Chinese preschoolers during the COVID-19 pandemic. Methods: Four hundred and eighteen preschoolers (226 males; 4.0 [0.6] y old) from Zhuhai, China, completed the device-based physical activity (PA) and sedentary behavior measures, and sleep duration was reported by parents at baseline (October 2021 to December 2021). FMS was assessed using the Test of Gross Motor Development: Third Edition at 1-year follow-up (October 2022 to December 2022). The compositional analysis and isotemporal substitution were used. Results: Moderate to vigorous PA (MVPA) was positively associated with locomotor skills and ball skills (P <.05), and light physical activity was negatively associated with locomotor skills (P <.05) during the COVID-19 pandemic. FMS improvements were linked to the addition of MVPA at the expense of light physical activity, sedentary behavior, and sleep. The estimated detriments to FMS were larger in magnitude than the estimated benefits of time reallocation from MVPA to light physical activity, sedentary behavior, and sleep. Conclusions: This study provides evidence about 24-hour movement behaviors and FMS during the COVID-19 pandemic and highlights the importance of participating in MVPA to improve preschoolers' FMS development during the COVID-19 era.

The vaccine, a distinctive product with specific characteristics, plays a crucial role in enhancing human immunity against diseases for their eradication. Given the severe impact of the COVID-19 pandemic on humanity, numerous challenges lie ahead, underscoring the necessity to develop and enhance medical, economic, and managerial components of vaccine development, as well as to integrate digital technologies and coordinate all stakeholders to respond effectively to the epidemic. All of these considerations refer to the need for a vaccine lifecycle management approach. Despite existing literature, many studies focus on isolated stages, neglecting the essential holistic view required to understand interconnections and the overall impact of proposed solutions on the whole lifecycle. This study addresses this research gap, by systematically tackling major challenges throughout the vaccine lifecycle. Our research contributes to the literature by (a) providing a systematic examination of the literature surrounding Vaccine Lifecycle Management, offering insights into the existing challenges and issues faced in the various stages of vaccine development, production, distribution, and administration, and (b) proposing recommendations or directions for improvement in managing the entire lifecycle of vaccines. Our results could be valuable perspectives for decision-makers involved in the process. [ABSTRACT FROM AUTHOR]

Background: Detraining is the partial or complete loss of physical training-induced adaptations as a result of exercise interruption or reduction. The COVID-19 pandemic led to the discontinuation of many older adult exercise programs and led to increased depressive symptoms (DS), increased sedentary behavior (SB), and decreased quality of life (QoL). Objective: To evaluate the effects of detraining, in the pandemic, on physical capacity and its relationship with DS, QoL, and SB of community-dwelling older adults. Methods: The physical capacity (static balance, dynamic balance, and lower limb and handgrip strength) of 35 participants was assessed prepandemic and after 18 and 24 months of the pandemic. DS, QoL, and SB were evaluated only at 18-month period. The analysis of variance for repeated measures or the Friedman and Pearson or Spearman tests were used for statistical analysis. Results: There was a decline in dynamic balance (p <.001) and strength in the lower limbs (p <.001) in the first 18 months, as well as maintenance in the following 6 months. The reduction in dynamic balance during the 18 months of the pandemic was associated with greater DS (p =.015; r =.414) and worse QoL (p =.024; r = −.381) in this period. More time spent on SB (p =.024; r =.386) in the 18th month was associated with worse dynamic balance in the following 6 months. Conclusion: Detraining in the pandemic setting led to long-lasting harmful effects, which can last for 2 years, on the physical capacity of community-dwelling older adults. Implication: Our findings highlight how periods of detraining can interfere in physical and mental health of older adults. [ABSTRACT FROM AUTHOR]

Employment relations in Europe today differ from how they were prior to the 2008 financial crisis and the COVID-19 pandemic, as key terms and conditions (e.g., wages) and sectors of economic activity (e.g., platform work and the green economy) are now subject to direct political intervention by the European institutions. Transnational (horizontal) competition within the Single European Market has long provided a context for national employment relations in Europe, and various national institutions impacted workers' rights and conditions of employment. Under the new economic governance (NEG) regime triggered by the financial crisis, political (vertical) intervention in employment relations created strong pressure toward the commodification of labor. The COVID pandemic involved policymaking in the opposite (decommodifying) direction. That said, and as the articles in this special issue clearly demonstrate, commodifying pressures are still strong, and the full realization of Social Europe is arguably as elusive as ever.

With the COVID-19 pandemic in the rear window, the sport industry ramped up efforts to evaluate the financial and cultural detriment of the global public health crisis. Therefore, this study aimed to assess how the altered sport and physical exercise habits of college students at Southeastern Conference (SEC) member institutions impacted their physical and mental well-being. Drawing from social ecology theory, data were collected through a qualitative online survey consisting of open-ended questions, disseminated via email to SEC college students. Study findings indicate the critical role of access to physical exercise and sports in the overall well-being of society and may prove invaluable for addressing future public health emergencies and crises. Theoretical and practical recommendations include the development of sustainable outdoor recreation activities as well as coping strategies and alternatives to traditional sports and physical exercise (e.g., immersive virtual reality options).

This study investigated the effect of a supplier's customer concentration level on its operating performance during the COVID-19 pandemic. Using a large sample of publicly listed U.S. manufacturing firms, we measured abnormal changes in operating performance of the sample firms across two distinct stages of the pandemic: the disruption phase ( $ N = 2,557 $ N = 2 , 557) and the recovery phase ( $ N = 2,454 $ N = 2 , 454). Our regression results show that the effect of customer concentration varied depending on the phase of the pandemic. Suppliers with a concentrated customer base performed worse during the first year of the pandemic when the global supply chain experienced significant disruptions. During this disruption, firms with lower degrees of customer concentration managed their supply chain risks more effectively, resulting in higher operating performance than their benchmark firms. However, when firms entered the recovery phase, we found that a firm's concentration level had the opposite effect on its operating performance. During the recovery phase, firms with concentrated customer bases could coordinate and collaborate more effectively with major customers, leading to improved operating performance. Based on our findings, we discuss the theoretical and managerial implications of managing the supply chain structure during its disruption and recovery. [ABSTRACT FROM AUTHOR]

Many public health experts worried that Robert F. Kennedy Jr.'s presidential campaign would elevate an anti-vaccine movement that's seen its reach and fundraising skyrocket since the COVID-19 pandemic. But a closer look at what's happening in state governments shows that Kennedy—America's most famous anti-vaxxer—isn't the leading edge of the anti-vaccine movements effort to make inroads in electoral politics. At a time when routine school vaccination rates are dropping to precarious lows in many places, the anti-vaccine movement has seen great success in getting supportive politicians elected, and notching previously unattainable wins in statehouses across the country.

This case study describes the adaptation process of a female sailor experiencing several career-change events and transitions. Qualitative data were collected longitudinally as part of a sport psychology consultation process. Data analysis was guided by the meta-model of adaption in sport. Along two Olympic cycles (i.e., Tokyo 2020 and Paris 2024), the athlete experienced multiple changes. These included two transitions between sailing classes, teaming up with a partner, long training camps, an injury, the coronavirus pandemic, and competing in major championships. Transition demands included building team cohesion and developing self-efficacy and mental strength. The athlete exhibited successful and poor adaptation. The applied work facilitating her successful adaptation is presented. Her adaptation ability developed as she progressed in her career, en route to becoming a world champion. These findings provided initial applied-practice support for the meta-model of adaption in sport. [ABSTRACT FROM AUTHOR]

The aim of the current study was to explore elite athletes' experiences of the COVID-19 pandemic and its impact on both growth and well-being. Informed by two complementary theoretical models, this research focused on elite athletes' potential to experience growth. Five elite athletes completed the Stress-Related Growth Scale–Revised and underwent semistructured interviews to develop a narrative of their experiences. Through a thematic analysis, we articulated elite athletes' experiences of both illusory and real adversarial growth following the COVID-19 pandemic. Four themes illustrated their experiences: the COVID-19 experience, searching for positives, self-transformation, and the social impact. A fifth theme, well-being, was integral throughout, involving the continued protection and development of athlete well-being. Future research recommendations and implications include further exploration of adversarial growth experiences after the pandemic and long-term effects of the pandemic on elite athletes, the creation of an adversarial growth measure, and engagement with this research to inform support measures to decrease the impact of adversity on elite athletes' well-being.

We estimate the superstar effects in Major League Baseball, focusing on a particularly unique international athlete, Shohei Ohtani, using a fixed effects panel regression with multiway clustering. Ohtani's scarce talent as both a pitcher and a hitter provides the potential to have outsized influence on demand at home (superstar effect) and away (superstar externality) games, providing new marketing opportunities for the league. We compare Ohtani's impact on attendance with other top pitchers, particularly after large attendance drops attributed to the COVID-19 pandemic, suggesting that his superstardom played a key role in bringing fans back to baseball games. Results revealed a large attendance externality, especially after the pandemic, that increased away attendance by up to 40% in 2021 specifically (and up to 20% overall). We propose that Ohtani provides an opportunity for Major League Baseball to leverage a recognizable face of baseball and leverage superstar value that was previously shown to be in decline.

The SARS-CoV-2 pandemic strongly influenced daily practices, and this manifested in social interactions, communications and consumption. This work addresses the relations between branding and cultural trends in strategic communication and advertising in different contexts of the pandemic. First, we reviewed the concepts of branding and cultural trends. From there, it was necessary to develop a methodological proposal to articulate a connotative semiotic analysis with the semiotic square and a cultural trend mapping. The analysis was carried out through an independent and comparative reading of two-time phases: confinement (2020) and end of constraints (2022). Three telecommunications brands in Portugal act as case studies in a random and probabilistic sample of two audiovisual texts from Christmas campaigns each. Finally, a theoretical-operational triangulation is obtained between branding, cultural trends and semiotic analysis in promoting local brands that redefine spaces, social relations, and identity expression during and after the COVID-19 pandemic confinements.

A two-sided "credit-line channel"—relating to drawdowns and repayments—explains the severe drop and partial subsequent recovery in bank stock prices during the COVID-19 pandemic. Banks with greater exposure to undrawn credit lines saw larger stock price declines but performed better outside of crises periods. Despite deposit inflows, high drawdowns led to reduced bank lending, suggestive of capital encumbrance upon drawdowns. Repayments of credit lines unencumbered capital which explains the stock price recovery starting Q2 2020. Bank provision of credit lines resembles writing put options on aggregate risk, and we propose how to incorporate this feature into bank stress tests. [ABSTRACT FROM AUTHOR]

Banks' information technology (IT) capabilities affect their ability to serve customers during the COVID-19 pandemic, which generates an unexpected and unprecedented shock that shifts banking services from in-person to digital. Amid mobility restrictions, banks with better IT experience larger reductions in physical branch visits and larger increases in website traffic, implying a larger shift to digital banking. Stronger IT banks are able to originate more Paycheck Protection Program loans to small business borrowers, especially in areas with more severe COVID-19 outbreaks, higher internet use, and higher bank competition. Those banks also attract more deposit flows and receive better mobile customer reviews during the pandemic. [ABSTRACT FROM AUTHOR]

This case study examined the English soccer player Marcus Rashford's personal brand and illustrates the transformational difference celebrity athletes can make through social activism and advocacy for philanthropic causes through their skillful use of social media. It employed a textual analysis methodology and drew conceptual insights from the revised Model of Athlete Brand Image to chronicle how Rashford's social activism and philanthropy resonated with his fans, followers, and the public on social media. His authentic social activism and philanthropic advocacy for disadvantaged and vulnerable children gave the nation a "feel-good" story during the COVID-19 crisis and enhanced his personal brand image. This case study recommends that future analyses of celebrity athlete personal brands should consider including three new categories in the marketable life section of the revised Model of Athlete Brand Image: social activism, cobranding partnerships, and awards and honors.

Social distancing measures are typically recommended to contain the spread of infectious diseases. To improve the public's voluntary compliance, governments and health authorities seek to publicize timely information about the pandemic. Yet social planners may exaggerate or downplay their private information about the disease's severity to elicit their preferred level of social distancing. This is because the relative weight they assign to the costs of isolation over public health may be unbalanced, and people may not fully consider how their social distancing may influence others' infection risk. Consequently, messages and claims about the pandemic may be distrusted. The author investigates whether and when communication can be fully or partially credible despite apparent incentives for misrepresentation. The author finds that a government would communicate truthfully in equilibrium if and only if the disease severity levels are not too close to each other in the public's prior belief. Nevertheless, an increasing difference between the severity levels need not enhance the credibility of communication. Greater communication credibility may hurt social welfare. Moreover, as the government becomes more concerned about the costs of social distancing, its equilibrium messages may become more or less trustworthy. The article's results can benefit social planners and users of their messages (e.g., analysts, researchers, investors). [ABSTRACT FROM AUTHOR]

By applying institutional theory in retail and COVID-19 settings, this paper investigates the impact of legitimacy dimensions on customer loyalty, considering the moderating effect of the perceived COVID-19 threat. The data collected by a consumer survey in Japan and Croatia were analysed using Structural Equation Modelling. The results from both samples reveal that moral and cognitive legitimacy are critical loyalty drivers. The perceived COVID-19 threat moderated the relationship between cognitive legitimacy and loyalty. The study also reveals some differences between the countries. The impact of pragmatic legitimacy is significant only in Croatia, while perceived threat negatively moderates the relationship between moral legitimacy and loyalty only in Japan. The study provides recommendations for managers on how to gain loyalty through actions supporting legitimacy. [ABSTRACT FROM AUTHOR]

Background/Objectives: This study investigated adherence to physical activity (PA) guidelines and associated sociodemographic factors among older Koreans from 2011 to 2020. Methods: Utilizing four public data sets from the National Survey of Older Koreans, the study included the data on 40,993 older adults 65 years and older in South Korea, collected between 2011 and 2020. Adherence to PA guidelines and sociodemographic factors were assessed through self-reported questionnaires. The data were analyzed using a two-way analysis of variance and post hoc tests. Results: Overall adherence increased from 39.1% in 2011 to 48.2% in 2017, then decreased to 37.6% in 2020 (p <.001). Men had higher adherence than women (p <.001). Age-related adherence peaked in the young-older group (65–74 years old) and was lowest in the oldest-old group (85+ years old) (p <.001). Marital status, education, and income were also significantly related to PA adherence (p <.001) across the years. Conclusion: Although continuous increase in adherence to PA among Koreans 65 years and older was observed, the decline in PA levels during the COVID era underscored the need for targeted interventions and well-informed health care policies to address demographic challenges. Still, considering that data were collected during the recommended social distancing period, a cautions interpretation of these findings is warranted. Significance/Implications: Health policies aiming to improve adherence to PA guidelines should prioritize Korean older adults who are female, belong to the oldest-old group, are single, and have low education and income levels, with the goal of enhancing health equity.

This paper investigates the role of short-term economic dynamism in responding to crisis induced supply shortages. We focus on the domestic manufacturing ramp-up of surgical masks, respirators, and their intermediary products in response to the COVID-19 pandemic. We develop a novel method for timely identification and validation of the evolving state of domestic manufacturing. To unpack the activities of domestic manufacturers and related institutions, we triangulate across 56 qualitative interviews, certifications, Thomasnet.com®, industry associations, and other public data. We find that while large manufacturers could rapidly scale up, onshore, or diversify production to enter into domestic production of critical medical supplies, these large manufacturers alone were insufficient to meet the spike in demand. In face of this shortage, small and medium enterprises (SME), who entered into mask and respirator production as de novo firms, spin-offs, and by diversifying, were important in increasing overall domestic capacity and serving markets unmet by large hospital distributors. These firms often had fewer competencies and resources compared to larger firms, and received less effective government support. Despite these disadvantages, a number of SMEs succeeded in entering into domestic production, and our interviews suggest this capacity could have been better integrated into the national response. We propose new theory for how and when federal and state governments should support short-term economic dynamism (firm entry into target products and/or markets) during crises to address supply shortages, and the types of market and network failures federal or state governments may be most effective at addressing.

The authors investigate how race and political partisanship affected variations in workplace and non-workplace mobility at three COVID-19 phases—lockdown (2020), reopening (2021), and endemic COVID (2022). They theorize that structural racism compelled relatively greater workplace mobility rates in Black communities during lockdown, and reduced Black workplace mobility during reopening and endemic COVID. By contrast, they posit elite-level anti-science skepticism and its amplification resulted in Trump-voting communities experiencing relatively higher workplace and non-workplace mobility rates than non-Trump-voting areas throughout the pandemic. Regressions primarily using county-level Google Mobility Reports data support the hypotheses, conditioning on state-level fixed effects and county-level urbanity, COVID job-type sorting, demographics, and socioeconomics. The county-level results are complemented by outcomes from novel individual-level COVID lockdown survey data, helping connect the proposed individual-level mechanisms to the county-level findings. The authors conclude that work mobility during COVID was racialized and politicized, offering empirical insights into how systematic disadvantages can lead to increased and unequal precarity during periods of acute economic or social crisis.

The sudden onset of the COVID-19 pandemic ushered in an unprecedented era of public admiration for healthcare workers. Indeed, the title "healthcare heroes" became a ubiquitous moniker for healthcare providers of all stripes during the pandemic, a sentiment reflected in countless advertisements and banners. Paradoxically, these same "healthcare heroes" who were being publicly celebrated for their work in the fight against a novel coronavirus also faced stigma for their work amid the virus and infected patients. Using grounded theory, we document how stigmatized members of an occupation experience and respond to mixed—and even conflicting—social evaluations. We contribute to the literature on stigma and social evaluations more broadly by showing how targets of stigma evaluate their evaluators through nuanced logical and emotional processing and, moreover, that such processing can lead recipients of mixed evaluations toward a number of outcomes not previously theorized. We explore the concept of "dirty heroes," where workers are celebrated and stigmatized along distinct dimensions of work traditionally studied in dirty work (i.e., physical, social, and moral). Our findings further illustrate how high-legitimacy occupations can be subject to "hero-washing," whereby workers are publicly celebrated yet privately neglected. [ABSTRACT FROM AUTHOR]

During the first half of 2020, the difference in savings from mortgage refinancing between high- and low-income borrowers was 10 times higher than before. This was the result of two factors: high-income borrowers increased their refinancing activity more than otherwise comparable low-income borrowers and, conditional on refinancing, they captured slightly larger improvements in interest rates. Refinancing inequality increases with the severity of the COVID-19 pandemic and is characterized by an underrepresentation of low-income borrowers in the pool of applications. We estimate a difference of $5 billion in savings between the top income quintile and the rest of the market. [ABSTRACT FROM AUTHOR]

We examine how broad changes in work arrangements and lifestyles brought on by the COVID-19 pandemic have affected households' location decisions. Using data on over 360,000 residential, interstate moves over the last 5 years, we find that more than 12% of moves were directly influenced by the pandemic. Among pandemic-influenced movers, over 15% of households cite that remote work influenced their move. Lifestyle-related (job-related) migration increased (decreased) significantly, particularly for the set of households who are likely to have access to remote work. We further find that these changes in migration patterns are positively related to post-pandemic economic growth. [ABSTRACT FROM AUTHOR]

The outbreak of the Covid-19 pandemic led to restrictions in production worldwide. Numerous firms were affected and unable to keep up production due to lockdowns. In disruptive events like this, the resilience of the production system is of central importance, as the survivability of the entire firm depends on it. In this context, the literature argues that cutting-edge technologies, such as Artificial Intelligence (AI), raise the proactive and reactive capabilities of firms, enabling them to better resist and recover from disruptive events and thus, show a higher resilience. This paper takes up this topic and observes the Covid-19 pandemic with the aim to analyse whether a firm's AI-readiness had an impact on its production resilience during the spring 2020 lockdown in Germany. For this purpose, we combine two large-scale surveys containing data from 237 manufacturers in Germany and test hypotheses based on quantitative analyses. Our results show that firms could indeed benefit from AI-enabled production during the lockdown. However, it is also clear that manufacturers have to exceed a certain AI threshold to significantly increase their resilient capabilities and realise positive effects. Our findings not only hold implications for research, but also provide recommendations for the resilience management of manufacturers. [ABSTRACT FROM AUTHOR]

The ever-happening disruptive events interrupt the operationalisation of manufacturing organisations resulting in stalling the production flow and depleting societies with products. Advancements in cutting-edge technologies, viz. blockchain, artificial intelligence, virtual reality, digital twin, etc. have attracted the practitioners' attention to overcome such saddled conditions. This study attempts to explore the role of artificial intelligence (AI) in building the resilience of production function at manufacturing organisations during a COVID-19 pandemic. In this regard, a decision support system comprising an integrated voting analytical hierarchy process (VAHP) and Bayesian network (BN) method is developed. Initially, through a comprehensive literature review, the critical success factors (CSFs) for implementing AI are determined. Further, using a multi-criteria decision-making (MCDM) based VAHP, CSFs are prioritised to determine the prominent ones. Finally, the machine learning based BN method is adopted to predict and understand the influential CSFs that help achieve the highest production resilience. The present research is one of the early attempts to know the essence of AI and bridge the interplay between AI and production resilience during COVID-19. This study can support academicians, practitioners, and decision-makers in assessing the AI adoption in manufacturing organisations and evaluate the impact of different CSFs of AI on production resilience.

This study investigated fiction readers' motivations for reading, their relevant needs regarding the fiction attributes, and their expectations for future fiction recommendation services. Seventy-six participants shared their fiction search and reading experiences through an open-ended, free-writing-style online survey. Findings show that readers' motivations (a sense of connection, comfort and safety, diverse selection, escapism, coping with stressful circumstances) and corresponding fiction elements (e.g., author's background information, themes, mood) were closely related to the situations or contexts that readers experienced, especially so for stress stemming from the COVID-19 pandemic.

This study, which is based on actual events, presents a dynamic analysis of the development, implementation, and post-implementation review of establishing an enterprise risk management (ERM) system for a U.S. multinational nonprofit firm over a 5-year period, 2015–2020. Using the Risk and Insurance Management Society Risk Maturity Model (RIMS RMM), questionnaire-based risk data and multi-dimensional risk mapping indices are used to identify and prioritize the firm's key strategic risks leading to the development of mitigation strategies whose performance are reviewed post ERM implementation, including during the 2020 Coronavirus pandemic. The results reveal that the firm's risk management system has been ad hoc and uncoordinated. Post-implementation review of the ERM program shows improvements in financial and operating positions resulting from risk diversification, enhanced profitability, exploitation of natural hedges, and improved board governance. The results further show that the recommended mitigation strategies have been effective in managing the adverse impact of the pandemic. Overall, the evidence offered in this study provides further support on the valuation benefits of ERM maturity within a real-world environment. [ABSTRACT FROM AUTHOR]

Background: To evaluate the influence of previous physical activity (PA) during childhood, adolescence, and current PA practice on the production of antibodies and inflammatory response between the first and second doses of the COVID-19 vaccine. Methods: Fifty-nine men and 56 women were evaluated before the first vaccine, and 12 weeks later, blood samples were taken to quantify production of anti-severe acute respiratory syndrome coronavirus-2 immunoglobulin G antibodies and cytokines. Previous PA during childhood and adolescence was self-referred, and current PA was assessed using the International Physical Activity Questionnaire. Results: A positive and significant association was observed only between PA practice during adolescence and an increase in antibody production in adulthood (β = 2012.077, 95% confidence interval, 257.7953–3766.358, P =.025). Individuals who practiced PA during adolescence showed higher production of antibodies between the first and second vaccine dose compared to nonpractitioners (P =.025) and those that accumulated ≥150 minutes per week of current moderate–vigorous PA (MVPA), and presented higher antibody production in relation to who did <150 minutes per week of MVPA (P =.046). Individuals that were practitioners during childhood produced higher G-CSF (P =.047), and those that accumulated ≥150 minutes per week of current MVPA demonstrated lower IP-10 levels (P =.033). However, PA practitioners during adolescence presented higher G-CSF (P =.025), IL-17 (P =.038), IL-1RA (P =.005), IL-1β (P =.020), and IL-2 (P =.026) levels. Conclusion: Our results suggest that adults that accumulated at least 150 minutes of MVPA per week or practiced PA during adolescence developed an improved immune and inflammatory response against COVID-19 vaccination.

With heightened uncertainties and risks in the fluctuating business environment, existing studies have concentrated on elucidating how service organizations leverage human resource practices to adapt to and survive such unforeseen and disruptive threats. However, how such practices could serve the strategic objective of cultivating a sustainably thriving workforce across different situations is not well understood. Thriving is a core transitional state that fosters positive behaviors, such as creative customer‐related problem‐solving. Applying social information processing theory, we propose and test a model by exploring how organizations that engage in thriving‐oriented human resource management (HRM) encourage employees to take responsibility and promote constructive change, thereby activating their creative problem‐solving behaviors. Specifically, we theorize and develop measures to promote thriving‐oriented HRM in Study 1. In Study 2, we collected multisource and multi‐wave data from 296 frontline service employees and 45 supervisors in China. Our findings reveal that thriving‐oriented HRM is positively related to felt responsibility for change, which ultimately encourages creative problem‐solving. We also show that the threat imposed by a crisis, that is, the COVID‐19 pandemic, strengthens the positive relationship between thriving‐oriented HRM and felt responsibility for change. Our study contributes to the HRM literature, especially on thriving‐oriented HRM and employee perception, and has practical implications for service organizations in the uncertain context.

PurposeThe novel coronavirus pneumonia (COVID-19) has continually spread and mutated, requiring a patient risk stratification system to optimize medical resources and improve pandemic response. We aimed to develop a conformal prediction-based tri-light warning system for stratifying COVID-19 patients, applicable to both original and emerging variants.MethodsWe retrospectively collected data from 3646 patients across multiple centers in China. The dataset was divided into a training set (n = 1451), a validation set (n = 662), an external test set from Huoshenshan Field Hospital (n = 1263), and a specific test set for Delta and Omicron variants (n = 544). The tri-light warning system extracts radiomic features from CT (computed tomography) and integrates clinical records to classify patients into high-risk (red), uncertain-risk (yellow), and low-risk (green) categories. Models were built to predict ICU (intensive care unit) admissions (adverse cases in training/validation/Huoshenshan/variant test sets: n = 39/21/262/11) and were evaluated using AUROC ((area under the receiver operating characteristic curve)) and AUPRC ((area under the precision-recall curve)) metrics.ResultsThe dataset included 1830 men (50.2 %) and 1816 women (50.8 %), with a median age of 53.7 years (IQR [interquartile range]: 42-65 years). The system demonstrated strong performance under data distribution shifts, with AUROC of 0.89 and AUPRC of 0.42 for original strains, and AUROC of 0.77-0.85 and AUPRC of 0.51-0.60 for variants.ConclusionThe tri-light warning system can enhance pandemic responses by effectively stratifying COVID-19 patients under varying conditions and data shifts.

BACKGROUND: The COVID-19 pandemic led to dramatic changes in the lives of children that impact cardiometabolic health. Cities and counties had varying policies with respect to school closure, recreational programs, and efforts to mitigate food insecurity and economic distress. Our objective was to evaluate changes in BMI-z score and prevalence of overweight/obesity prior to and during the pandemic among children in San Francisco, CA, where public schools were closed for 18-months. METHODS: This was an electronic medical record-based retrospective cohort study. We included 15,401 children, 4-17 years of age at study onset. Our exposure was time into each of three time periods: (1) March 2018-February 2019; (2) March 2019-February 2020; (3) March 2020-August 2021 (the pandemic period of school closure). Generalized estimating equations (GEE) were used to assess changes in BMI-z score and overweight/obesity across the three time periods. We assessed for effect modification by age-category, insurance status, and race/ethnicity. RESULTS: Mean BMI-z score increased by 0.06 per year in time period 2, the year prior to the pandemic (p
