AbstractBackgroundA rapid increase in cases due to the SARS-CoV-2 Omicron (B.1.1.529) variant in highly vaccinated populations has raised concerns about the effectiveness of current vaccines.MethodsWe used a test-negative case-control design to estimate vaccine effectiveness (VE) against symptomatic disease caused by the Omicron and Delta variants in England. VE was calculated after primary immunisation with two BNT162b2 or ChAdOx1 doses, and at 2+ weeks following a BNT162b2 booster.ResultsBetween 27 November and 06 December 2021, 581 and 56,439 eligible Omicron and Delta cases respectively were identified. There were 130,867 eligible test-negative controls. There was no effect against Omicron from 15 weeks after two ChAdOx1 doses, while VE after two BNT162b2 doses was 88.0% (95%CI: 65.9 to 95.8%) 2-9 weeks after dose 2, dropping to between 34 and 37% from 15 weeks post dose 2.From two weeks after a BNT162b2 booster, VE increased to 71.4% (95%CI: 41.8 to 86.0%) for ChAdOx1 primary course recipients and 75.5% (95%CI: 56.1 to 86.3%) for BNT162b2 primary course recipients.For cases with Delta, VE was 41.8% (95%CI: 39.4-44.1%) at 25+ weeks after two ChAdOx1 doses, increasing to 93.8% (95%CI: 93.2-94.3%) after a BNT162b2 booster. With a BNT162b2 primary course, VE was 63.5% (95%CI: 61.4 to 65.5%) 25+ weeks after dose 2, increasing to 92.6% (95%CI: 92.0-93.1%) two weeks after the booster.ConclusionsPrimary immunisation with two BNT162b2 or ChAdOx1 doses provided no or limited protection against symptomatic disease with the Omicron variant. Boosting with BNT162b2 following either primary course significantly increased protection.
Application of multi-edge HERFD-XAS to assess the uranium valence electronic structure in potassium uranate (KUO3)
Authors: Bes René , Leinders Gregory , Kvashnina Kristina 
Published: December 2021

The uranium valence electronic structure in the prototypical undistorted perovskite KUO3 is reported on the basis of a comprehensive experimental study using multi-edge HERFD-XAS and relativistic quantum chemistry calculations based on density functional theory. Very good agreement is obtained between theory and experiments, including the confirmation of previously reported Laporte forbidden f–f transitions and X-ray photoelectron spectroscopic measurements. Many spectral features are clearly identified in the probed U-f, U-p and U-d states and the contribution of the O-p states in those features could be assessed. The octahedral crystal field strength, 10Dq, was found to be 6.6 (1.5) eV and 6.9 (4) eV from experiment and calculations, respectively. Calculated electron binding energies down to U-4f states are also reported.
An economic analysis of nontraditional lending in Chapter 12 bankruptcy cases
Authors: Rabinowitz Adam N. , Secor William Glen 
Published: December 2021

PurposeNontraditional lenders are important credit providers for farmers. However, previous research has found that farmers who use nontraditional lenders are riskier lending opportunities. Using a unique dataset of Chapter 12 bankruptcy cases, the authors analyze the share of payment that is made or allowed by the courts on debt owed to traditional and nontraditional lenders.Design/methodology/approachThe authors use a Tobit model to calculate parameter estimates and marginal effects of the impact of creditor type (traditional/nontraditional) and debt classification (secured, priority and unsecured) on the proportion of a bankruptcy claim that lenders receive or are expected to receive when a case is discharged.FindingsThe authors find that traditional lenders with secured debt receive a greater repayment than nontraditional lenders. Meanwhile, there are more than twice the number of nontraditional lenders that are owed debt in these bankruptcy claims. While this raises concern for nontraditional lenders, that is mitigated some by the level of debt that is on average about one-sixth the size of the average debt of traditional lenders. Finally, the authors show there are numerous opportunities for future research in this area using case level bankruptcy data.Originality/valueThis paper fills a research gap by focusing on the state of nontraditional lenders in Chapter 12 bankruptcy cases and their treatment in discharged cases.

Gendered impacts of climate-smart agriculture on household food security and labor migration: insights from Bihar, India
Authors: Agarwal Tripti , Goel Prarthna Agarwal , Gartaula Hom , Rai Munmum , Bijarniya Deepak , Rahut Dil Bahadur , Jat M.L. 
Published: December 2021

Purpose
Increasing trends of climatic risk pose challenges to the food security and livelihoods of smallholders in vulnerable regions, where farmers often face loss of the entire crop, pushing farmers (mostly men) out of agriculture in destitution, creating a situation of agricultural making agriculture highly feminization and compelling male farmers to out-migrate. Climate-smart agricultural practices (CSAPs) are promoted to cope with climatic risks. This study aims to assess how knowledge related to CSAPs, male out-migration, education and income contribute to the determinants of male out-migration and CSAPs adoption and how they respond to household food security.

Design/methodology/approach
Sex-disaggregated primary data were collected from adopter and non-adopter farm families. STATA 13.1 was used to perform principle component analysis to construct knowledge, yield and income indices.

Findings
Yield and income index of adopters was higher for men than women. The probability of out-migration reduced by 21% with adoption of CSAPs. An increase in female literacy by 1 unit reduces log of odds to migrate by 0.37. With every unit increase in knowledge index, increase in log-odds of CSAPs adoption was 1.57. Male:female knowledge gap was less among adopters. Non-adopters tended to reduce food consumption when faced with climatic risks significantly, and the probability of migration increased by 50% with a one-unit fall in the nutrition level, thus compelling women to work more in agriculture. Gender-equitable enhancement of CSAP knowledge is, therefore, key to safeguarding sustainable farming systems and improving livelihoods.

Social implications
The enhancement of gender equitable knowledge on CSAPs is key to safeguard sustainable farming systems and improved livelihoods.

Originality/value
This study is based on the robust data sets of 100 each of male and female from 100 households (n = 200) using well-designed and validated survey instrument. From 10 randomly selected climate-smart villages in Samastipur and Vaishali districts of Bihar, India, together with focus group discussions, the primary data were collected by interviewing both men and women from the same household.

Key factors driving customers’ restaurant dining behavior during the COVID-19 pandemic
Authors: Jeong Miyoung , Kim Kawon , Ma Forest , DiPietro Robin 
Published: December 2021

Purpose
This study aims to identify key factors that affected US respondents’ dining behavior at restaurants during the midst of the COVID-19 pandemic.

Design/methodology/approach
Due to the lack of a prior framework or model to test customers’ perceptions of dining-out behavior during this unprecedented time, this study used a mixed-methods approach, conducting two focus group discussions to generate potential restaurant attributes, followed by a US-based survey using an online panel. Using structural equation modeling, this study tested eight developed propositions.

Findings
The findings of this study indicated that the three key factors (i.e. restaurant dining environment, communication and hygiene and contactless features) made customers feel comfortable dining in the restaurant during the pandemic. Out of these three factors, only the restaurant dining environment and communication and hygiene were essential predictors for customers’ perceived trust toward the restaurant, leading to their willingness to pay more. This study used two moderators, customers’ perceived risk and support for restaurants to examine how they affected customers’ perceived trust and willingness to pay, respectively.

Practical implications
This study provides both theoretical and practical implications to the current body of knowledge in customers’ dining-out behavior and the development of operational strategies for restaurants to accommodate customers’ changing dining-out behavior due to the COVID-19 pandemic. To develop a holistic conceptual framework, this study incorporates two COVID-19-focused measurement items, perceived risk and support of the restaurant, to identify their moderating roles in the relationships among the five proposed measurement items. This study provides restaurant operators with insights into the altered dining-out behavior of their customers due to the COVID-19 pandemic and prepares them for the post pandemic environment.

Originality/value
During the unprecedented pandemic situation, few customers are willing to dine in restaurants. As local and national governments lifted the mandated COVID-19 protocols, restaurants opened their business slowly to cater to customers in compliance with the centers for disease control’s health and safety regulations. It is of utmost importance for restaurant operators to accommodate their customers’ needs when they dine in the middle of the COVID-19 pandemic. There is a paucity of research that has examined customers’ comfort level when dining in restaurants and customers’ preferred dining environment during the pandemic.
What triggers mobile application-based purchase behavior during COVID-19 pandemic: evidence from Vietnam
Authors: Le Xuan Cu 
Published: December 2021

PurposeCoronavirus disease 2019 (COVID-19) has shifted purchase behavior and accelerated the diffusion of modern retail channels via mobile application (or m-application). This work aims to frame a mechanism of m-application-based behavioral intentions in the COVID-19 context.Design/methodology/approachThe authors designed a web-based survey to retrieve empirical data from 478 Vietnamese users. Quantitative approach and structural equation modeling (SEM) were employed to test a research model.FindingsFindings reveal that antecedents of Unified Theory of Acceptance and Use of Technology (UTAUT) (i.e. performance expectancy and facilitating conditions), external influences (i.e. perceived imitation), m-application-related factors (i.e. additive value and alternative attractiveness) and COVID-19-related factors of Protective Motivation Theory (PMT) (i.e. perceived contraction threat, fear and social distancing) are determinants of use intention. Moreover, COVID-19-related dimensions and use intention have direct and indirect positive influences on purchase intention.Practical implicationsPractitioners should stay agile and focus greater attention on a mechanism in which consumer adoption and purchase intention are formulated in the pandemic.Originality/valueThis work narrows the gap by simultaneously identifying the importance of the dimensions from UTAUT and COVID-19-related factors from PMT, especially social distancing, integrated with additive value and alternative attractiveness of m-applications in forming the behavioral intention model in a disease context.
When and whom should retailers offer price reductions in times of crisis?
Authors: Jeong Haeyoung , Bhatt Siddharth , Ye Hongjun , Zhang Jintao , Suri Rajneesh 
Published: December 2021

PurposeWith a decrease in consumer spending during the coronavirus disease 2019 (COVID-19) pandemic, many retailers are offering price reductions to stimulate demand. However, little is known about how consumers perceive such price reductions executed during turbulent times. The authors examine whether the timing of price reductions and individual differences impact consumers' evaluations of the retailers offering such reductions.Design/methodology/approachUsing a longitudinal design, the authors inquire into four retailers' motives that consumers may infer from a price decrease at two different times during the COVID-19 crisis.FindingsThe authors find that the timing of price reductions plays a key role in shaping consumers' inference of retailers' motives. The authors also uncover individual characteristics that affect consumers' inferences.Originality/valueThis research advances the literature by demonstrating the critical role of timing and individual characteristics in consumers' perceptions of price reductions during times of crisis. The authors findings also provide retailers with actionable insights for their pricing strategies. The findings may be generalizable to other types of crises that may arise in the future.
Assessing the role of venturesomeness in a destination consumer-based brand equity model
Authors: Cruz-Milán Oliver 
Published: December 2021

PurposeGiven the lack of research on the nomological validity of tourism destination consumer-based brand equity (CBBE) constructs incorporating core, well-established constructs from the travel and tourism discipline, this research investigates the influence of venturesomeness as a moderator in a model with destination image, satisfaction, and overall CBBE as antecedents of return intentions.Design/methodology/approachThe study uses online panel data of past visitor to the sea-side destination of Corpus Christi, Texas. A sample of 210 residents in Texas and surrounding states was employed to estimate the hypothesized effects through partial least squares-structural equation modeling (PLS-SEM).FindingsResults demonstrate the predictive effects of destination CBBE dimensions on tourists' revisit intention, with the significant moderation effects of venturesomeness through its influence on tourist satisfaction.Research limitations/implicationsFindings provide general support to the nomological validity of the proposed model, highlighting the role of satisfaction as a central dimension to explain destination loyalty, the limitations of generic scales to investigate tourism destination contexts, and the incorporation of consumers' psychographics and lifestyle variables on destination CBBE.Practical implicationsDestination marketers should develop segmentation strategies to target travelers with psychographic profiles that are more responsive to the factors that foster CBBE.Originality/valueThis research provides insights on the nomological validity of a CBBE model by evaluating its integration with a context-specific theoretical domain, which is a condition to increase the explanatory scope of theoretical relations and claims in intermediate theory, and to move the research field forward.
Exploring the factors influencing adoption of health-care wearables among generation Z consumers in India
Authors: Nayak Bishwajit , Bhattacharyya Som Sekhar , Kumar Saurabh , Jumnani Rohan Kumar 
Published: December 2021

PurposeThe purpose of this study is to identify the major factors influencing the adoption of health-care wearables in generation Z (Gen Z) customers in India. A conceptual framework using push pull and mooring (PPM) adoption theory was developed.Design/methodology/approachData was collected from 208 Gen Z customers based on 5 constructs related to the adoption of health-care wearables. Confirmatory factor analysis and structural equation modelling was used to analyse the responses. The mediation paths were analysed using bootstrapping method and examination of the standardized direct and indirect effects in the model.FindingsThe study results indicated that the antecedent factors consisted of push (real-time health information availability), pull (normative environment) and mooring (decision self-efficacy) factors. The mooring factor (MOOR) was related to the push factor but not the pull factor. The MOOR, in turn, was related to the switching intention of Gen Z customers for health wearables adoption.Research limitations/implicationsThe research study extended the literature related to the PPM theory in the context of the adoption of health wearables among Gen Z customers in India.Practical implicationsThe study outcome would enable managers working in health wearable organizations to understand consumer behaviour towards health wearables.Social implicationsThe use of health wearables among Gen Z individuals would lead to future generations adopting a healthy lifestyle resulting in an effective workforce and better economy.Originality/valueThis was one of the few studies which have explored the PPM theory to explore the factors for the adoption of health wearables among Gen Z customers in India.
Consuming in a crisis: pandemic consumption across consumer segments and implications for brands
Authors: Basu Meheli , Swaminathan Vanitha 
Published: December 2021

Purpose
This paper aims to understand how the Covid-19 pandemic has changed consumers’ perceptions of outdoor consumption categories, such as retail shopping, eating out, public events and travel and how these perceptions may impact businesses in these domains in the long term. Further, this research aims to understand demographic effects on outdoor consumption inhibition during the current pandemic and discuss how businesses can use these insights to rebrand their offerings and evolve after the pandemic.

Design/methodology/approach
Data collected by CivicScience, a survey-based consumer intelligence research platform, during April–July 2020 forms the basis of the preliminary analysis, where the chi-square test has been used to examine significant differences in consumer attitudes between different age groups, income groups and genders. Further, a social media analysis of conversations around outdoor consumption activities is undertaken to understand the rationale behind these demographics-based attitude differences.

Findings
Results lend varying degrees of support to the hypothesized consumer attitudes toward outdoor consumption activities during the Covid-19 pandemic. As the pandemic wore on, older (vs younger), female (vs male) consumers and lower (vs higher) income-group consumers had reportedly higher inhibition toward different outdoor activities. Older individuals were significantly less likely to shop, dine and attend public events than younger individuals. Lower-income consumers were significantly less likely to dine and travel than higher-income consumer consumers. Female consumers were significantly less likely to shop and travel than male consumers. Social media scan of conversations suggests that differences in perceived health and financial risks may have resulted in demographics-based differences in outdoor consumption activities.

Research limitations/implications
This study contributes to the literature by understanding demographic differences in consumer participation in outdoor activities. One limitation is that due to the time-sensitive nature of the pandemic research, further studies could not be conducted to understand the implications of other variables, beyond demographics that influence consumer behavior during a crisis. A future research direction is to understand how other psychological variables or traits, influence health and financial risk-taking behavior during a similar crisis.

Originality/value
The principal contribution of the present research is that it tests the risk-taking theory in the context of outdoor consumption during the Covid-19 pandemic. The present research has implications for businesses as they continue to evolve during and post Covid-19.
