Published: December 2021

AbstractThe Omicron variant of SARS-CoV-2 is causing a rapid increase in infections in various countries. This new variant of concern carries an unusually high number of mutations in key epitopes of neutralizing antibodies on the spike glycoprotein, suggesting potential immune evasion. Here we assessed serum neutralizing capacity in longitudinal cohorts of vaccinated and convalescent individuals, as well as monoclonal antibody activity against Omicron using pseudovirus neutralization assays. We report a near-complete lack of neutralizing activity against Omicron in polyclonal sera after two doses of the BNT162b2 vaccine, in convalescent individuals, as well as resistance to different monoclonal antibodies in clinical use. However, mRNA booster immunizations in vaccinated and convalescent individuals resulted in a significant increase of serum neutralizing activity against Omicron. Our study demonstrates that booster immunizations will be critical to substantially improve the humoral immune response against the Omicron variant.
Organizational citizenship behaviors perceived by collectivistic 50-and-older customers and medical-care service performance: an application of stimulus-organism-response theory
Authors: Kim Wooyang , Hantula Donald A. , Di Benedetto Anthony 
Published: December 2021

PurposeThe study aims to examine the underexplored agenda in organizational citizenship behaviors (OCBs) through the collectivistic 50-and-older customers' lens when encountering medical-care services by applying stimulus-organism-response (S-O-R) theory.Design/methodology/approachThe authors propose an integrative causal model derived from employees OCBs perceived by the collectivistic 50-and-older outpatients in Korean medical-care organizations and test the causal relationships using structural equation modeling (SEM).FindingsThe three dimensions of OCBs are external stimuli to the synergistic relationship of both cognitive and affective organisms for enhancing the organization's external outcomes. The customers' organismic processes mediate the relationships between OCBs and the resultant outcomes. Customer satisfaction plays a pivotal role in determining customers' future behavior when converting the business relationship to friendship.Practical implicationsThe proposed integrated model provides an overall mechanism of the collectivistic customer decision process in the medical-care service setting. The integrated model helps to understand better how customers proceed mental and emotional states with the encountered services and how frontline employees offer extra-roles beyond in-roles to their customers in touching points to maintain superior organizational performance.Originality/valueThe authors respond to the underexplored agenda in the OCB research discipline. The study is one of the few studies to examine the effect of OCBs from collectivistic customers' perspectives and apply a consumer behavior theory to explain a service organizational performance in an integrative causal model.
Maximum entropy snapshot sampling for reduced basis modelling
Authors: Bannenberg Marcus W.F.M. , Kasolis Fotios , Günther Michael , Clemens Markus 
Published: December 2021

Purpose
The maximum entropy snapshot sampling (MESS) method aims to reduce the computational cost required for obtaining the reduced basis for the purpose of model reduction. Hence, it can significantly reduce the original system dimension whilst maintaining an adequate level of accuracy. The purpose of this paper is to show how these beneficial results are obtained.

Design/methodology/approach
The so-called MESS method is used for reducing two nonlinear circuit models. The MESS directly reduces the number of snapshots by recursively identifying and selecting the snapshots that strictly increase an estimate of the correlation entropy of the considered systems. Reduced bases are then obtained with the orthogonal-triangular decomposition.

Findings
Two case studies have been used for validating the reduction performance of the MESS. These numerical experiments verify the performance of the advocated approach, in terms of computational costs and accuracy, relative to gappy proper orthogonal decomposition.

Originality/value
The novel MESS has been successfully used for reducing two nonlinear circuits: in particular, a diode chain model and a thermal-electric coupled system. In both cases, the MESS removed unnecessary data, and hence, it reduced the snapshot matrix, before calling the QR basis generation routine. As a result, the QR-decomposition has been called on a reduced snapshot matrix, and the offline stage has been significantly scaled down, in terms of central processing unit time.
The Lean principle respect for people as respect for craftsmanship
Authors: Ljungblom Mia , Lennerfors Thomas Taro 
Published: December 2021

Purpose
The purpose of this paper is to reach a deeper understanding of the Lean principle of respect for people (RFP to facilitate Lean implementation in Western organizations outside Toyota.

Design/methodology/approach
This study uses an interpretative, hermeneutic approach to understand the RFP concept through a literature study of existing research about Lean implementation, and an inquiry into the underlying meaning of the RFP principle, by studying sources from Toyota and discussions about the RFP principle in Japan.

Findings
RFP is seen as a central principle in Lean implementations, but the failure of RFP is believed to cause Lean implementations to fail. The literature about Lean discusses the RFP principle both as a general positive atmosphere and as focused on developing the work capacity of employees. By studying the sources from Toyota, it could be understood that RFP is based on ought-respect. The authors also find that RFP is related to takumi, a perfected form of craftsmanship. The authors translate the concept to English by tying it to the recent literature about craft to develop RFP as RFC – respect for craftsmanship.

Research limitations/implications
As this is a conceptual paper, it is difficult to translate the findings into a tool for companies and organizations to use. However, that is the point of the paper: that the most important ideas are not translatable into tools.

Practical implications
It is necessary in Lean implementations to connect people’s work to craftsmanship. Through a discussion of craftsmanship before Lean implementations, it might be possible to nurture an understanding of the underlying values of Lean.

Originality/value
The authors have not found any papers that propose takumi as the base of the RFP principle, nor as a foundational concept at Toyota. It is necessary to understand the concept of takumi, as perfection in craft, to understand the RFP principle.

Authors: Naeem Muhammad Abubakr , Raza Rabbani Mustafa , Karim Sitara , Billah Syed Mabruk 
Published: December 2021

Purpose
This study aims to examine the hedge and safe-haven properties of the Sukuk and green bond for the stock markets pre- and during the COVID-19 pandemic period.

Design/methodology/approach
To test the hedge and safe-haven characteristics of Sukuk and green bonds for stock markets, the study first uses the methodology proposed by Ratner and Chiu (2013). Next, the authors estimate the hedge ratios and hedge effectiveness of using Sukuk and green bonds in a portfolio with stock markets.

Findings
Strong safe-haven features of ethical (green) bonds reveal that adding green bonds into the investment portfolios brings considerable diversification avenues for the investors who tend to take fewer risks in periods of economic stress and turbulence. The hedge ratio and hedge effectiveness estimates reveal that green bonds provide sufficient evidence of the hedge effectiveness for various international stocks.

Practical implications
The study has significant implications for faith-based investors, ethical investors, policymakers and regulatory bodies. Religious investors can invest in Sukuk to relish low-risk and interest-free investments, whereas green investors can satisfy their socially responsible motives by investing in these investment streams. Policymakers can direct the businesses to include these diversifiers for portfolio and risk management.

Originality/value
The study provides novel insights in the testing hedge and safe-haven attributes of green bonds and Sukuk while using unique methodologies to identify multiple low-risk investors for investors following the uncertain COVID-19 pandemic.

Exploring micro-foundations of dynamic capabilities for social enterprises
Authors: Bhardwaj Rohit , Srivastava Saurabh , Taggar Rashi , Bindra Sunali 
Published: December 2021

Purpose
Social enterprises (SEs) operate with a primary goal of meeting a social purpose while creating economic wealth for the fulfillment of their primary mission. These organizations need to develop a certain set of capabilities that facilitates the successful pursuit of their dual mission goals. This paper aims at exploring the micro-foundations of dynamic capabilities (DCs) that enable SEs to recognize and exploit opportunities and reconfigure their resources to pursue their dual-mission goals and adjust with the environmental dynamics.

Design/methodology/approach
This study uses a multiple case design and an abductive research approach to conduct an in-depth and in-due course investigation of the development of DCs in two distinct SEs selected on the basis of theoretical-purposive sampling and availability of the richness of the information about them.

Findings
This study finds certain generic and exclusive micro-foundations of DCs that contribute to sensing opportunities, seizing opportunities and reconfiguring resources in SEs. The exclusive micro-foundations of DCs of SEs noted in this study are sustainability of beneficiaries, involving beneficiaries in decision-making, defining unique business models and selective suppliers for critical resources.

Research limitations/implications
The limitation of this study lies in its dependence on retrospective data, which may perhaps influence the comprehensiveness and accuracy of the acquired data. This study, although, implemented the measures to minimize the bias, by supplementing the interview data with archival sources.

Practical implications
To the researchers, this study proffers an in-depth and in-due course explanation of the micro-foundations of DCs that facilitate SEs to sense opportunities, seize opportunities and reconfigure their resources with time. To practitioners working in the area of social entrepreneurship, this process study is an outline of reference that answers the how and why concerning the importance of micro-foundations of DCs for SEs.

Originality/value
To the best of the authors’ knowledge, no prior study has explored the micro-foundations of DCs in the context of SEs from emerging economies. The exclusive micro-foundations of DCs for SEs found in this study are the unique and original contribution that outlines the path for future academic inquiry in this evolving research area.
Analytical and numerical analyses of filling progression and void formation in flip-chip underfill encapsulation process
Authors: Ng Fei Chong , Abas Aizat , Nashrudin Muhammad Naqib , Tura Ali M. Yusuf 
Published: December 2021

Purpose
This paper aims to study the filling progression of underfill flow and void formation during the flip-chip encapsulation process.

Design/methodology/approach
A new parameter of filling progression that relates volume fraction filled to filling displacement was formulated analytically. Another indicative parameter of filling efficiency was also introduced to quantify the voiding fraction in filling progression. Additionally, the underfill process on different flip-chips based on the past experiments was numerically simulated.

Findings
All findings were well-validated with reference to the past experimental results, in terms of quantitative filling progression and qualitative flow profiles. The volume fraction filled increases monotonically with the filling displacement and thus the filling time. As the underfill fluid advances, the size of the void decreases while the filling efficiency increases. Furthermore, the void formed during the underfilling flow stage was caused by the accelerated contact line jump at the bump entrance.

Practical implications
The filling progression enabled manufacturers to forecast the underfill flow front, as it advances through the flip-chip. Moreover, filling progression and filling efficiency could provide quantitative insights for the determination of void formations at any filling stages. The voiding formation mechanism enables the prompt formulation of countermeasures.

Originality/value
Both the filling progression and filling efficiency are new indicative parameters in quantifying the performance of the filling process while considering the reliability defects such as incomplete filling and voiding.
Human papillomavirus self‐sampling: A tool in cancer prevention and sexual health promotion
Authors: Mamo Laura , Pérez Ashley E. , Rios Lucy 
Published: December 2021

AbstractThis article examines human papillomavirus (HPV) self‐sampling as an approach to cervical cancer prevention and the ways self‐sampling kits are promoted directly to consumers in the United States. Public health, biomedicine and health tech have increasingly imagined self‐sampling, which allows individuals to collect their own vaginal specimen, mail to a laboratory for testing and receive delivered results, as a component of cervical cancer prevention and sexual health promotion. This article examines the scientific and biomedical claims used to configure the problem in need of this solution and the ways persons, publics and markets are established. We analyse scientific literature, interviews with clinicians and other key actors, and websites of directly to consumers (DTC) companies. HPV self‐sampling is constructed as both a solution to inequities and gaps in cervical cancer screening and a solution to the wants and needs of those already engaged in self‐projects of body monitoring and risk reduction. These multidirectional biomedical tendencies also reveal how sexuality and sexual health and cervical cancer prevention and sexual health promotion are entangled objects. While we do not want to undermine the potential of HPV self‐sampling, we encourage a focus on equity and care and not commodified markets that reinforce notions of ‘good’ patients monitoring their health.
Bouguer Gravity Anomaly in the Andean Orogenic Belt and its Dynamic Implications for Regional Tectonic Evolution
Authors: ZHU Xiaosan , LU Minjie , ZHENG Hongwei 
Published: December 2021

AbstractCalculated Bouguer gravity anomalies from the Andean orogenic belt interpreted as derived from regional gravity data to aid understanding of the lithospheric structure and tectonic evolution of the belt. These anomalies reveal lithospheric structures distributed throughout the belt, including linear and circular structures. NE‐trending structures reflect sinistral transpression across the northern part of the belt, and NW‐trending structures represent dextral transtension in the southern part. These results are supported by gravity‐anomaly patterns that demonstrate mantle flow in a trench‐parallel direction both northward and southward away from the stagnation band that is beneath the subducting Nazca slab. This mantle flow has served as an important driving force in the evolution of the Andean orogenic belt. Features of the modified tectonic model of the Andean orogenic belt are consistent with the spatial variation in and interpretation of Bouguer gravity anomalies.
Giomer composite compared to glass ionomer in occlusoproximal ART restorations of primary molars: 24‐month RCT
Authors: Pássaro AL , Olegário IC , Laux CM , Oliveira RC , Tedesco TK , Raggio DP 
Published: December 2021

AbstractBackgroundOcclusoproximal restorations of primary molars usually fail, so it is necessary to investigate new materials that may overcome this challenge. Thus, this trial aimed to evaluate the longevity of occlusoproximal ART restorations in primary molars using a glass ionomer cement – GIC (Equia Forte® – GC Corp) and a Giomer resin composite – GCR (Beautifil Bulk Restorative® – Shofu Inc) after 24 months.MethodsOne hundred and eighty‐two (182) children aged from 4 to 8 years were selected and randomly assigned to GIC or GCR. A paediatric dentist treated them in the school setting in Cerquilho, Brazil, and the restorations were assessed after 3, 6, 12, 18 and 24 months. The primary outcome was the restoration survival, evaluated using the Kaplan–Meier and superiority Cox regression analyses. Intention to treat (ITT) was performed as a sensitivity analysis using superiority test P value and confidence interval (CI = 95%). Independent variables included gender, age, molar, jaw, cavity volume and caries experience.ResultsThe restoration survival after 24 months was GIC = 58.1% and GCR = 49.1% (HR = 1.24; CI = 0.97–1.59). ITT analysis showed a success of GIC = 61.1% and GCR = 52.2% (RR = 1.17; CI = 0.91–1.52). The superiority hypothesis was not proved in both analyses (P > 0.05).ConclusionGCR does not have superior longevity than GIC in occlusoproximal ART restorations of primary molars.

SummaryCopy number variants (CNVs) are genomic structural variations that contribute to many adaptive and economically important traits in livestock. In this study, we detected CNVs in 354 animals from 16 Russian indigenous sheep breeds and analysed their possible functional roles. Our analysis of the entire sample set resulted in 4527 CNVs forming 1450 CNV regions (CNVRs). When constructing CNVRs for individual breeds, a total of 2715 regions ranging from 88 in Groznensk to 337 in Osetin breeds were identified. To make interbreed CNVR frequency comparison possible, we also identified core CNVRs using CNVs with overlapping chromosomal locations found in different breeds. This resulted in 137 interbreed CNVRs with frequency >15% in at least one breed. Functional enrichment analysis of genes affected by CNVRs in individual breeds revealed 12 breeds with significant enrichments in olfactory perception, PRAME family proteins, and immune response. Function of genes affected by interbreed and breed‐specific CNVRs revealed candidates related to domestication, adaptation to high altitudes and cold climates, reproduction, parasite resistance, milk and meat qualities, wool traits, fat storage, and fat metabolism. Our work is the first attempt to uncover and characterise the CNV makeup of Russian indigenous sheep breeds. Further experimental and functional validation of CNVRs would help in developing new and improving existing sheep breeds.
