Health-based crisis: how do firms weather the storms using the structural hole-bridging strategy?
Authors: Cheah Chee Wei , Koay Kian Yeik 
Published: March 2023

Purpose
Drawing on the structural hole-bridging perspective of network theory, this paper aims to examine the adaptation strategies undertaken by housing industry actors following the recent pandemic.

Design/methodology/approach
A qualitative case study was adopted as the research methodology for this research. Data collected through online interviews involving 20 participants was used as primary data, while document analysis (both online and printed documents) was used as secondary data. The interviews were guided by the visual vignette method.

Findings
This study’s findings indicate that a health-based crisis like COVID-19 triggers housing developers to act outside their comfort zones. They undertake arbitrage and collaborative brokerage strategies to cope with business uncertainties. This study revealed the contextual embedding of the owner-occupier market (consumer market) and the investor market (business market). This study also revealed that firms that aggressively located structural holes and built new relationships in B2C and B2B markets before the COVID-19 pandemic were well-equipped to face turbulent times.

Practical implications
The innovative strategies that housing developers adopt are transferable and applicable to other industries and countries. Therefore, awareness of these strategies is essential for industry practitioners, especially those badly hit by health-based crises.

Originality/value
To the best of the authors’ knowledge, this is the first empirical study that combines relationship management, structural holes, the housing market and their implications for crisis adaptation. This study examined the grossly understudied phenomenon of demand for housing, which is a durable good, during a turbulent time. The findings of this study provide beneficial guidance for firms, buyers and policymakers facing COVID-19 and/or other similar crises.

PurposeThis study aims to establish the statistical relationships between corporate real estate added value indicators of cost reduction, increasing productivity, risk reduction and flexibility and organizational financial and non-financial performance.Design/methodology/approachThe study adopted a mixed methods approach which encompasses initial expert interviews and subsequent questionnaire surveys. Partial least squares structural equation modelling was applied to test the proposed hypotheses of the study.FindingsThe results highlight the significant influence of three added value indicators on organizational performance while highlighting the need for strategic corporate real estate risk management to enhance performance.Practical implicationsThe results of the study are useful to identify relevant added value indicators that can improve organizational performance as well as potential added value indicators that deserve attention for performance improvement. Moreover, it presents knowledge on corporate performance indicators which is sparsely explored in corporate real estate management literature.Originality/valueThis study makes a novel contribution to corporate real estate management literature by presenting a parsimonious model to alert corporate real estate managers on essential added value parameters towards organizational performance. The model set the theoretical debates to exploit additional added value dimensions and organizational performance.
Ecological footprint in a global perspective: the role of domestic investment, FDI, democracy and institutional quality
Authors: Emmanuel Ongo Nkoa Bruno , Fonchamnyo Dobdinga Cletus , Thierry Mamadou Asngar , Dinga Gildas Dohba 
Published: March 2023

Purpose
The continuous increase in the negative gap between biocapacity and ecological footprint has remained globally persistent since early 1970. The purpose of this study is to examine the effect of foreign capital, domestic capital formation, institutional quality and democracy on ecological footprint within a global panel of 101 countries from 1995 to 2017.

Design/methodology/approach
The empirical procedure is based on data mix. To this end, this study uses a battery of testing and estimation approaches both conventional (no cross-sectional dependence [CD]) and novel approaches (accounting for CD). Among the battery of estimation techniques used, there are the dynamic ordinary least square, the mean group, the common correlation effect mean group technique, the augmented mean group technique, the Pooled mean group and the dynamic common correlation effect technique with the desire to obtain outcomes robust to heteroskedasticity, endogeneity, cross-correlation and CD among others.

Findings
The estimated outcomes indicate that using different estimators’ domestic capital formation consistently degrades the environment through an increase in ecological footprint, while institutional quality consistently enhances the quality of the environment. Further, the outcome reveals that, though foreign capital inflow degrades the environment, the time period is essential, as it shows a short-run environmental improvement and a long-run environmental degradation. Democratic activities show a mixed outcome with short-run degrading effect and a long-run enhancement effect on environmental quality.

Practical implications
Green investment should be the policy target of all economies, and these policies should be adopted to target both domestic capital and foreign capital alike. Second, the adoption of democratic practices will produce good leaders that will not just design short-term policies to blindfold the populace temporary but those that will produce long-term-oriented practices that will better and enhance the quality of the environment through the reduction of the global footprint. Equally, enhancing the institutional framework like respect for the rule of law in matters of abatement should be encouraged.

Originality/value
Although much research on the role of macroeconomic indicators on environmental quality has been done this far, democratic practices, intuitional quality and domestic capital have been given little attention. This research fills this gap by considering robust empirical techniques.
The effect of memory and stiffness on energy ratios at the interface of distinct media
Authors: Barak M.S. , Kumar Rajesh , Kumar Rajneesh , Gupta Vipin 
Published: March 2023

PurposeThis paper aims to study the energy ratios of plane waves on an imperfect interface of elastic half-space (EHS) and orthotropic piezothermoelastic half-space (OPHS).Design/methodology/approachThe dual-phase lag (DPL) theory with memory-dependent derivatives is employed to study the variation of energy ratios at the imperfect interface.FindingsA plane longitudinal wave (P) or transversal wave (SV) propagates through EHS and strikes at the interface. As a result, two waves are reflected, and four waves are transmitted, as shown in Figure 2. The amplitude ratios are determined by imperfect boundaries having normal stiffness and transverse stiffness. The variation of energy ratios is computed numerically for a particular model of graphite (EHS)/cadmium selenide (OPHS) and depicted graphically against the angle of incidence to consider the effect of stiffness parameters, memory and kernel functions.Research limitations/implicationsThe energy distribution of incident P or SV waves among various reflected and transmitted waves, as well as the interaction of waves for imperfect interface (IIF), normal stiffness interface (NSIF), transverse stiffness interface (TSIF), and welded contact interface (WCIF), are important factors to consider when studying seismic wave behavior.Practical implicationsThe present model may be used in various disciplines, such as high-energy particle physics, earthquake engineering, nuclear fusion, aeronautics, soil dynamics and other areas where memory-dependent derivative and phase delays are significant.Originality/valueIn a variety of technical and geophysical scenarios, wave propagation in an elastic/piezothermoelastic medium with varying magnetic fields, initial stress, temperature, porosity, etc., gives important information regarding the presence of new and modified waves.
The yin and yang of employee voice: an exploratory study
Authors: Goel Apoorva , Khan Nabila , Dyaram Lata 
Published: March 2023

PurposeThis study examines the yin (promotive) and yang (prohibitive) of employee voice based on employee preference for voice channel attributes. Employee inputs may be disregarded, requiring employees to maneuver for unheeded voice and adopt alternate voice tactics. The authors emphasize the ubiquity of lurking employee silence and its affective effects on subsequent cycles of voice or silence.Design/methodology/approachQualitative design involving semi-structured interviews of employees from service sector firms in India assisted the inquiry.FindingsEmployees prefer voice channel attributes that ensure visibility and data substance for promotive voice and anonymity and confidentiality for prohibitive voice. Voice target switching and message reframing were common employee strategies. Silence on both sharing views/opinions (promotive) and voicing issues/concerns (prohibitive) weakens employee future voice incidents, besides suppressing the affect. Post-silence cognitive reappraisal increases voice incidences.Research limitations/implicationsFindings may have limited generalizability given the qualitative design of the study. Moving beyond extant episodic voice research, the authors demonstrate the recurrent nature of employee voice and silence. The study broadens perspectives on how varied voice types necessitate nuanced voice channel attributes.Originality/valuePresent work brings together organizational behavior (OB) perspective on discretionary voice through human resource (HR)-based channels, helping bridge the gap between previously disparate stands.
Nothing to lose: the rationales of grassroots financial innovations in contexts of extreme scarcity
Authors: Zapata Campos Maria Jose , Barinaga Ester , Dimba Kiaka Richard , Ocampo Juan 
Published: March 2023

Purpose
Highly deprived urban contexts, such as informal settlements in the global south, can turn into niches of extreme innovation and sparkle ingenuity out of necessity. But what are the rationales behind the participation of disadvantaged communities in social innovations? Why do they engage in grassroots innovations? What is it that makes these grassroots try novelties and continue experimenting with them, even when the perceived benefits are not clear yet? This paper aims to examine and conceptualize the rationales for engaging in grassroots financial innovations in the context of extremely deprived urban settings.

Design/methodology/approach
This paper is based on the case of grassroots organizations which have started experimenting with the development of a community currency in Kisumu, Kenya. This paper is informed by in-depth interviews with members of three grassroots organizations involved in the community currency, together with observations and meeting participation since 2019.

Findings
The rationales argued by the participants for engaging in this grassroots innovation are framed in various ways: as a means for seeking poverty alleviation (the development framing); as a challenge to conventional imaginaries of innovations (the digital framing); and as an innovation embedded in community and trust relations (the community framing). These framings have a mobilizing effect that initially draws participants into the innovation. Yet, what explains persistent participation despite the decreasing influence of these framings over time is the organizational space and strategies of incompleteness accommodating these experiments.

Originality/value
This paper contributes to the emerging body of grassroots innovations movements literature. While research has progressed in its understandings of the challenges of scaling up innovative practices, the examination of the grassroots initiatives stemming from extremely deprived settings, and the rationales and framings behind, have been under examined. This paper comes to bridge this gap.
Travel duration and the restorative effects of holiday experiences: an inverted U-shape
Authors: Cui Rui 
Published: March 2023

Purpose
Restorative experiences relieve fatigue or stress, leading people to feel more energetic. Activation theory and the nature–dose framework hold travel duration as a crucial influence on restorative effects, yet these factors may not demonstrate a simple linear relationship. This paper, thus, aims to explore the relationship between travel duration and restoration based on a survey conducted during a seven-day holiday (the longitudinal data spanned two months); and explore the reasons for this relationship and the mechanisms for lasting restorative effects based on diary analysis.

Design/methodology/approach
Mixed methods were used in this study. Questionnaires regarding restorative effects were administered to 232 people at six time points before, during and after a holiday. Participants were also asked to keep a diary during their trips. Data were first tested for common method bias and were then processed via independent sample t-tests, analysis of variance and time-series analysis.

Findings
Restorative effects were consistently higher in the travel group than in the non-travel group. Additionally, an inverted U-shaped relationship emerged between travel duration and the restorative effects of a holiday; a moderate duration had stronger restorative effects than a duration that was too long or too short. More importantly, the study found that participants who traveled for a moderate duration (longer or shorter) engaged in non-judgmental challenging (relaxing) activities at least once. They also demonstrated greater eudaimonism (hedonism) and stronger, more sustained restoration versus the original set point. In addition, results revealed how travel activities, emotions, moderators and restorative effects were constructed.

Originality/value
Longitudinal data indicated an inverted U-shaped relationship between travel duration and restoration. Achieving lasting restorative effects requires effort and non-judgmental challenging activities for a moderate travel duration and frequency. The study uncovered mechanisms influencing the relationship between travel experiences and restorative effects. The results offer guidance for research on “travel prescriptions” and for the health and stress relief market.

Visual abstract
Inverted U-shaped curve for different travel durations and restorative effects at T3.
The non-judgmental challenging group showed lasting and stronger restorative effects over the next two months.
Numerical scrutinization of micropolar and Walters-B non-Newtonian fluids motion under the influence of thermal radiation and chemical reaction
Authors: Ayegbusi Florence Dami , Doungmo Goufo Emile Franc , Tchepmo Patrick 
Published: March 2023

Purpose
The purpose of this study is to explore numerical scrutinization of micropolar and Walters-B non-Newtonian fluids motion under the influence of thermal radiation and chemical reaction.

Design/methodology/approach
The two fluids micropolar and Walters-B liquid are considered to start flowing from the slot to the stretching sheet. A magnetic field of constant strength is imposed on their flow transversely. The problems on heat and mass transport are set up with thermal, chemical reaction, heat generation, etc. to form partial differential equations. These equations were simplified into a dimensionless form and solved using spectral homotopy analysis method (SHAM). SHAM uses the basic concept of both Chebyshev pseudospectral method and homotopy analysis method to obtain numerical computations of the problem.

Findings
The outcomes for encountered flow parameters for temperature, velocity and concentration are presented with the aid of figures. It is observed that both the velocity and angular velocity of micropolar and Walters-B and thermal boundary layers increase with increase in the thermal radiation parameter. The decrease in velocity and decrease in angular velocity occurred are a result of increase in chemical reaction. It is hoped that the present study will enhance the understanding of boundary layer flow of micropolar and Walters-B non-Newtonian fluid under the influences of thermal radiation, thermal conductivity and chemical reaction as applied in various engineering processes.

Originality/value
All results are presented graphically and all physical quantities are computed and tabulated.
Two‐dimensional inversion of airborne radiometric data for source concentrations: Application to Cu–Au targeting at Mara Rosa Magmatic Arc, Brazil
Authors: Weihermann Jessica Derkacz , Oliveira Saulo Pomponet , Li Yaoguo , Silva Adalene Moreira , Ferreira Francisco José Fonseca 
Published: March 2023

AbstractAirborne radiometrics (radiometric surveying) has been used in many applications, such as geological mapping, environmental studies, mineral exploration and lithology mapping. The standard processing of gamma‐ray spectrometry data provides good results when the acquisition conditions such as the flight and sensor orientation are constant. In practice, abrupt changes in flight height when flying in mountainous terrain are common, and standard processing neglecting this factor can lead to erroneous interpretation. The primary cause is the fact that the successive corrections applied to radiometric data in standard processing do not consider the effective sampled area of a survey (i.e. the field of view), which can have significant and variable overlaps between adjacent samples due to changing observation height. For this reason, standard height and sensitivity corrections may lead to incorrect estimates of the concentrations of the radioelements on the ground. To ameliorate this problem, we have developed a two‐dimensional inversion‐based processing method that incorporates the aircraft height, replaces the sensitivity correction and accounts for a positivity condition using a logarithmic barrier. Some minerals associated with potassium, uranium and thorium allow the mapping of hydrothermal alteration, especially potassium which is an important constituent of hydrothermal fluids. We demonstrate the new methods by comparing the standard processing results with the inversion‐based processing of airborne gamma‐ray spectrometry data in the gold deposit‐rich area of Mara Rosa Magmatic Arc, Brazil. The inversion‐based processing results enhance the anomalies and suppress the interpolation artefacts as well as increase the signal‐to‐noise ratio. The application of airborne radiometric transformed maps also improved the footprint knowledge around Cu–Au mineralization and highlighted potential areas for further studies.
Least‐squares reverse time migration with flux‐corrected transport technique
Authors: Liang Chen , Huang Jianping , Song Cheng , Han Jiale 
Published: March 2023

AbstractDue to high computational costs and memory requirements, it is necessary to use coarse grids for least‐squares reverse time migration when processing large‐scale field data. According to the dispersion relation, strong numerical dispersion will occur in least‐squares reverse time migration images when the migration velocity of the shallow strata is low, reducing the resolution of the migration results. To overcome this shortcoming, we propose new least‐squares reverse time migration implementation method with a modified flux‐corrected transport technique. This algorithm involves two main steps: obtain an appropriate calibration parameter for flux‐corrected transport through forward modelling and perform least‐squares reverse time migration using flux‐corrected transport. We remove the non‐linear processing from conventional flux‐corrected transport algorithm often used in computational fluid dynamics based on the assumption that the seismic wavefield is relatively continuous and smooth without strong ripples, which makes it possible to apply flux‐corrected transport to least‐squares reverse time migration without increasing too much computation complexity. To suppress the numerical dispersion more effectively, the diffusion fluxes along the diagonal direction are added to flux‐corrected transport. Numerical tests on synthetic data and field data illustrate that compared to the conventional least‐squares reverse time migration method, the proposed method produces images with fewer migration artefacts, more accurate amplitudes and faster convergence speed on the coarse grids.
Have States Reduced Obesity by Legislating More Physical Activity in Elementary School?
Authors: von HIPPEL PAUL T. , FRISVOLD DAVID E. 
Published: March 2023

Policy Points
Between 1998 and 2016, 24 states and the District of Columbia passed laws meant to increase the time that children spent in physical education (PE) or other school‐based physical activity (PA).
Schools largely disregarded changes to PE/PA laws, which did not increase the time that children spent in PE or recess and did not reduce body mass index, overweight, or obesity.
Closer oversight of schools would be needed to improve compliance with state PE and PA laws. Yet, even with better compliance, we estimate that PE and PA policies would be inadequate to reverse the obesity epidemic. Policies should also address consumption, both inside and outside of school.
ContextTo control childhood obesity, leading medical organizations have recommended increasing the time that children spend in physical education (PE) and other school‐based physical activity (PA). Yet, it is unknown how many states have passed laws that codify these recommendations, and it is unknown what effect changing state laws has had on obesity or the time that children actually spent in PE and PA.MethodsWe joined state laws to national samples of 13,920 children from two different cohorts of elementary students. One cohort attended kindergarten in 1998; the other attended kindergarten in 2010; both cohorts were followed from kindergarten through fifth grade. We estimated the effects of changes to state laws in a regression with state and year fixed effects.FindingsTwenty‐four states and the District of Columbia increased the time that children were recommended or required to spend in PE or PA. These changes in state policies did not increase actual time spent in PE or recess, did not affect average body mass index (BMI) or BMI Z score, and did not affect the prevalence of overweight or obesity.ConclusionIncreasing the PE or PA time required or recommended by state laws has not slowed the obesity epidemic. Many schools have failed to comply with state laws. A back‐of‐the‐envelope calculation suggests that, even with better compliance, the legislated changes in PE laws might not have changed energy balance enough to reduce obesity prevalence.
