Is shame-proneness the missing link between social norms, policymaking and productive entrepreneurship?
Authors: Ojha Atma Prakash , Nandakumar M.K. 
Published: May 2021

PurposeThe purpose of the paper is to establish the need to study the shame-proneness trait of entrepreneurs – what is it and why is it important to study.Design/methodology/approachIn this conceptual paper, the authors argue that shame-proneness is an important understudied trait of entrepreneurs and put up a case for further research. The authors argue that shame-proneness moderates the effect of social acceptability on opportunity exploitation decisions. The authors also argue that productive entrepreneurship can be promoted and unproductive entrepreneurship can be prevented through policy intervention, and the level of intervention can be determined by knowing the shame-proneness level of entrepreneurs.FindingsThe key argument is the following: an entrepreneur is homo economicus and homo sociologicus, i.e. she is driven both by rational economic value consideration and by the prevalent social norms, which influence opportunity exploitation decisions. Since shame enforces compliance with social norms, it is vital to study entrepreneurs' shame-proneness to understand entrepreneurial founding across different regions. Knowing the level of shame-proneness of entrepreneurs in a given region would help the government devise effective interventions to promote productive entrepreneurship and deter unproductive or destructive entrepreneurship.Originality/valueThis paper is an original creation of the authors.

PurposeBlockchain technology, a key feature of the fourth industrial revolution, is receiving widespread attention and exploration around the world. Taking the coronavirus pandemic as an example, the purpose of this study to examine the application of blockchain technology from the perspective of epidemic prevention and control.Design/methodology/approachExploring multiple case studies in the Chinese context at various stages of deployment, this study documents a framework about how some of the major challenges associated with COVID-19 can be alleviated by leveraging blockchain technology.FindingsThe case studies and framework presented herein show that utilization of blockchain acts as an enabler to facilitate the containment of several COVID-19 challenges. These challenges include the following: complications associated with medical data sharing; breaches of patients' data privacy; absence of real-time monitoring tools; counterfeit medical products and non-credible suppliers; fallacious insurance claims; overly long insurance claim processes; misappropriations of funds; and misinformation, rumors and fake news.Originality/valueBlockchain is ushering in a new era of innovation that will lay the foundation for a new paradigm in health care. As there are currently insufficient studies pertaining to real-life case studies of blockchain and COVID-19 interaction, this study adds to the literature on the role of blockchain technology in epidemic control and prevention.
Linking marketing and supply chain management in the strategy of demand chains via a review of literature
Authors: Bai Bingfeng , Gao Junjun , Lv Yang 
Published: May 2021

Purpose
This paper aims to assess the links among these demand chain constructs by conducting a full-scale systematic review of all demand chain management (DCM) literature reviews published in marketing and operations management journals from 2013 to 2020. Marketing and supply chain management are central to DCM; thus, this study briefly describes the contributions to knowledge provided by the papers contained in this issue. In addition, some additional areas of research in which the DCM can be gainfully deployed are outlined.

Design/methodology/approach
This paper makes a systematic literature review of 70 literature samples by means of content analysis and comprehensive analysis. These approaches guarantee a replicable, rigorous and transparent research process and minimize researcher bias. The analytical categories required for the content analysis are defined along the constructs of marketing and supply chain management.

Findings
As can be expected, this paper highlights the key role of the two constructs in the strategy of DCM. In this light, the paper claims to provide evidence of a link between the constructs of marketing and supply chain management. This paper reviews the connotation of DCM through literature review, distinguishes the relationship between DCM and supply chain management from a strategic management perspective and discusses the future research direction.

Research limitations/implications
This study assesses the link between the strategic constructs of marketing and supply chain management through research embedded in literature reviews, pinpointing research gaps and potential future research directions in the field. Contributing to DCM theory building, a thorough review provides qualitative comparison of the link between marketing and supply chain management.

Originality/value
Although some literature reviews have been conducted in the past on the constructs of DCM, no full review of literature reviews aiming to test a strategic theoretical link in the demand chain related to supply chain and marketing.
Herding behavior and stock market conditions
Authors: Ah Mand Abdollah , Janor Hawati , Abdul Rahim Ruzita , Sarmidi Tamat 
Published: May 2021

Purpose
The purpose of this paper is to investigate whether market conditions have an effect on investors’ propensity to herd in an emerging economy’s stock market. Additionally, given the lack of research on Islamic behavioral finance, the authors further investigate if the herding phenomenon is distinct in Islamic versus conventional stocks.

Design/methodology/approach
The authors used daily data for the period of 1995–2016 according to the herding behavior model of Chang et al. (2000), which relies on cross-sectional absolute deviation of returns.

Findings
Findings reveal the herding behavior of investors among Shariah-compliant during up and down market exits with non-linear relationship to the market return, while for conventional stocks herding behavior does not exist with linear nor nonlinear relationships during the up and down market. Furthermore, for the whole market, herding behavior only exists during upmarket with a nonlinear relationship to the market return. However, this relationship is not significant. Moreover, the results of this study are robust with respect to the effect of the Asian and global financial crisis.

Practical implications
The findings are useful for investors to identify which market conditions are associated with rational and irrational behavior of investors.

Originality/value
Most of the theoretical and empirical studies on herding behavior have focused on developed countries. Only a few studies have paid attention to the herding behavior in Islamic financial markets, particularly in the context of an emerging market such as Malaysia. This study fills this void.
Dyeing of cotton fabric with Euclea divinorum extract using response surface optimization method
Authors: Manyim Scolastica , Kiprop Ambrose Kipchumba , Mwasiagi Josphat Igadwa , Achisa Cleophas Mecha , Odero Mark Peter 
Published: May 2021

Purpose
The majority of the synthetic dyes have been found to be non-biodegradable, toxic and carcinogenic. As a result, there has been a growing trend toward the use of natural dyes as alternates to synthetic dyes. This shift calls for more research to come up with more sources of natural dyes to satisfy their increasing demand. Euclea divinorum plant has been used traditionally as a source of dye, however, its textile dyeing properties have not been studied. This study aims to determine the textile dyeing properties of E. divinorum extract.

Design/methodology/approach
Optimization of dyeing conditions of Euclea divinorum natural dye extract on the cotton fabric was done using response surface methodology (RSM). The combined effects of examined dyeing conditions on the relative color strength (K/S) were studied using a central composite experimental design. Analysis of variance (ANOVA) was used to determine the significance of the statistical model generated for the study. Mordanting effects were measured using standard ISO wash, rub and lightfastness tests.

Findings
The optimum dyeing conditions were found to be 68 min, pH 3.3 and 82°C with color strength 0.609. Temperature and pH showed some interaction effects during the dyeing experiments. The predicted optimum K/S value was validated experimentally using the optimum conditions and was found to be in agreement with the experimental values. All the metallic mordants used enhanced the color strength and provided a variety of brown shades, therefore, a suitable alternative for the toxic synthetic dyes.

Originality/value
Optimization of dyeing conditions of Euclea divinorum dye on cotton using RSM and mordanting at optimal conditions has not been done elsewhere.
Managing glitches in collaborative product development with suppliers
Authors: Merminod Valéry , Le Dain Marie Anne , Frank Alejandro Germán 
Published: May 2021

PurposeThis paper aims to propose that knowing in practice can be used as a mechanism to enhance social exchange in collaborative new product development (NPD) with suppliers to reduce glitches. Practic00es of inter-organizational knowing should consider the levels of supplier involvement adopted.Design/methodology/approachThis paper studies two opposite situations of supplier involvement in NPD projects, namely, white and black box configurations. This paper adopts a qualitative comparative analysis method to identify necessary and sufficient configurations of knowing in practice in 36 projects from 3 different companies.FindingsSocial exchange is important even when the NPD collaboration is based on contractual relationships as in white and grey box collaborations. There are different combinations of practices for inter-organizational knowing that can limit glitches in each supplier configuration. This paper proposes a theoretical model that explains these relationships and contributions to the reduction of glitches.Originality/valueThis paper combines social exchange theory with knowing in practice in the supplier involvement context. The theoretical model contributes to the understanding of knowing in practice in white and black box configurations.
The pragmatic functions of religious expressions in Najdi Arabic
Authors: al-Rojaie Yousef Ibrahim 
Published: May 2021

PurposeThis study attempts to identify and analyze the pragmatic functions of religious expressions, that is, invocations that include the name of Allah (God), in naturally occurring social interactions in Najdi Arabic, which is spoken in Central Saudi Arabia.Design/methodology/approachDrawing on the speech act theory and politeness model, an analysis of the data illustrates that religious expressions, in addition to their prototypical religious meanings and uses in everyday interactions, are employed to communicate a wide range of pragmatic functions.FindingsThese include signaling the end of a conversation, persuading, mitigating and hedging, showing agreement and approval, reinforcing emphasis, expressing emotions, seeking protection from the evil eye, conveying skepticism and ambiguity, expressing humor and sarcasm, and showing respect and honor. The embedded multifunctional dimension of religious expressions in the present data is interpreted as serving as a politeness marker with which speakers promote both positive politeness (by showing solidarity, claiming common grounds, and building rapport) and negative politeness (by reducing imposition and emphasizing personal autonomy).Originality/valueThis study further highlights the interplay between religion, culture, and language use in Najdi Arabic.
Analysis of the frequency dependence characteristics of wave attenuation and velocity dispersion using a poroelastic model with mesoscopic and microscopic heterogeneities
Authors: He Y.‐X. , Wang S.X. , Sun C. , Tang G.Y. , Zhu W. 
Published: May 2021

ABSTRACTSeismic waves passing through partially saturated porous rocks produce pressure gradients in the fluid phase, and, hence, the resulting fluid flow is accompanied by various length scales. The major mechanism responsible for seismic attenuation and dispersion is arguably known as wave‐induced fluid flow between inhomogeneities of microscopic, mesoscopic and macroscopic scales. Previous studies have revealed that differentiating the influence of heterogeneities at various scales on wave attenuation within seismic exploration and sonic frequencies, nevertheless, is very difficult. This is because wave attenuation mechanisms due to different heterogeneities are practically impossible to be unrelated. Therefore, it is important for a more quantitative interpretation of the relative contribution of inter‐dependent energy loss mechanisms through improved understanding of the combined influences associated to the microscopic squirt flow and mesoscopic fluid flow. We introduce a scaled poroelastic model to evaluate frequency‐dependent attenuation and velocity dispersion characteristics by considering the combined presence of microscopic and mesoscopic heterogeneities. To do so, the capillarity effects are incorporated into the poroelastic model with random distributions of the sizes of mesoscopic‐scale heterogeneities. A range of pertinent scenarios are calculated, and the acoustic properties indicate wave attenuation decreases whereas the phase velocity increases corresponding to additional capillary forces. Meanwhile, numerical results of the proposed model were compared with experimental measurements of a tight sandstone to examine its validity. Results of numerical simulations suggest that seismic reflections produce more complicated signatures in the presence of an interbedded structure of a reservoir exhibiting velocity dispersion. Therefore, the proposed procedure can help in assessing the sensitivities of frequency‐dependent seismic signatures to reservoir fluid mobility and patch heterogeneities.

Abstract

Forest degradation through logging is pervasive throughout the world's tropical forests, leading to changes in the three‐dimensional canopy structure that have profound consequences for wildlife, microclimate and ecosystem functioning. Quantifying these structural changes is fundamental to understanding the impact of degradation, but is challenging in dense, structurally complex forest canopies.

We exploited discrete‐return airborne LiDAR surveys across a gradient of logging intensity in Sabah, Malaysian Borneo, and assessed how selective logging had affected canopy structure (Plant Area Index, PAI, and its vertical distribution within the canopy).

LiDAR products compared well to independent, analogue models of canopy structure produced from detailed ground‐based inventories undertaken in forest plots, demonstrating the potential for airborne LiDAR to quantify the structural impacts of forest degradation at landscape scale, even in some of the world's tallest and most structurally complex tropical forests.

Plant Area Index estimates across the plot network exhibited a strong linear relationship with stem basal area (R2 = 0.95). After at least 11–14 years of recovery, PAI was ~28% lower in moderately logged plots and ~52% lower in heavily logged plots than that in old‐growth forest plots. These reductions in PAI were associated with near‐complete lack of trees >30‐m tall, which had not been fully compensated for by increasing plant area lower in the canopy. This structural change drives a marked reduction in the diversity of canopy environments, with the deep, dark understorey conditions characteristic of old‐growth forests far less prevalent in logged sites. Full canopy recovery is likely to take decades.

Synthesis and applications. Effective management and restoration of tropical forests requires detailed monitoring of the forest and its environment. We demonstrate that airborne LiDAR can effectively map the canopy architecture of the complex tropical forests of Borneo, capturing the three‐dimensional impact of degradation on canopy structure at landscape scales, therefore facilitating efforts to restore and conserve these ecosystems.

Published: May 2021

Abstract

Rocky environments host rich levels of biodiversity and provide vital habitat for specialised organisms, range‐restricted species and a broad range of ectotherms adapted to saxicoline environments.

In Australia, rock habitat is being destroyed during soil amelioration practices associated with agricultural intensification. Advances in rock crushing technology, developed to expand or increase crop yields and efficiency, pose an undocumented threat to global biodiversity, especially reptiles dependent on non‐renewable rock habitat in agricultural landscapes. Rock removal is a legislated key threatening process in parts of Australia and will accelerate biodiversity loss if not mitigated.

We estimated reptile species’ range overlap with dryland cropping and modified pastoral regions within the Australian wheat‐sheep zone to assess the potential impacts of rock crushing practices. We examined species‐ and family‐richness within the impact zone and across bioregions within the impact zone, to identify areas where rock removal has the greatest potential to impact terrestrial and fossorial squamates.

Our analysis revealed that 159 potentially impacted reptile species occur within the study area, representing 16% of Australian terrestrial squamates. Fourteen of these species, including six threatened species, have more than 50% range overlap with areas of intensive agriculture, and include several endangered pygopodids, scincids and agamids.

Bioregions rich in rock and burrow‐dwelling reptiles include the Brigalow Belt South, Murray Darling Depression, Darling Riverine Plains, Eyre Yorke Block, Avon Wheatbelt, Nandewar, Flinders Lofty Block and New South Wales South Western Slopes.

Synthesis and applications. The conservation of reptiles in agricultural landscapes requires appropriate management and retention of surface rocks. Potential yield increases from destroying rock habitat to intensify or expand cropland will not compensate for the net loss of reptile populations dependent on non‐renewable resources. Financial incentives to prevent the expansion and transformation of non‐arable landscapes to cropland are required to prevent the ongoing loss of biodiversity.
How changes in spring and autumn phenology translate into growth‐experimental evidence of asymmetric effects
Authors: Zohner Constantin M. , Renner Susanne S. , Sebald Veronica , Crowther Thomas W. 
Published: May 2021

Abstract

Earlier leaf‐out and later autumn leaf senescence under climate warming have been linked to increases in plant productivity and ecosystem carbon uptake. Yet, despite the potential implications of shifting phenology for plant carbon uptake, the degree to which phenological changes affect overall plant growth and the partitioning between above‐ and below‐ground biomass remains unclear.

Here we use a 3‐year experiment to quantify changes in root and shoot growth of three woody plant species (two common European tree species, Fagus sylvatica and Quercus robur, and one shrub Lonicera xylosteum) under spring and autumn warming.

In both tree species, the magnitude—and in Quercus even the direction—of the effects of growing‐season length on growth depends on whether the warming happened in spring or in autumn. Each day earlier leaf‐out in response to warming resulted in total biomass increases of 0.8%–2.5%, whereas delayed senescence led to reductions of 0.2%–2.1%. Advances in leaf‐out also led to increased root‐to‐shoot biomass ratios because root growth was proportionally more stimulated than shoot growth. In the shrub species, earlier leaf‐out had no effect, while delayed senescence led to increases in root, but not shoot, biomass.

Synthesis. The strong asymmetry between growth responses to spring versus autumn phenology demonstrates that growing‐season length per se is a weak indicator of individual‐level tree productivity. The results further imply that phenological shifts are reshaping the functional balance between above‐ and below‐ground growth, which is critical for quantifying forest carbon dynamics under climate change.
The pollination seesaw of Rhynchospora cephalotes (L.) Vahl (Cyperaceae): Influence of plant location on the role of wind and insects as pollen vectors
Authors: da Costa Ana Carolina Galindo , Thomas William Wayt , Machado Isabel Cristina 
Published: May 2021

AbstractAmbophily (wind and insect pollination) has been reported for some genera of the typically wind‐pollinated family Cyperaceae, including the genus Rhynchospora. The significance of wind and insect pollination can vary, depending on local microclimatic conditions. Rhynchospora cephalotes is an ambophilous species that can grow under different environmental conditions, either along forest edges or inside forest fragments. This study, therefore, tests the hypothesis that (a) there is greater contribution by wind than insects to fruit set of the individuals at the forest edge and (b) there is greater contribution by insects than wind to fruit set of the individuals inside the forest. Field work was carried out in a fragment of Atlantic Forest in northeastern Brazil. We quantified the number of visits by insects, wind velocity and the reproductive success (fruit set) of R. cephalotes provided by wind and insects through exclusion experiments performed at the edge of and inside the forest. We observed a greater number of visits per day by pollinating bees to individuals inside the forest (36.83 ± 7.46) than to individuals at the edge (16.66 ± 6.53). The wind speed was significantly higher at the edge (1.71 ± 0.46 m/s) than inside the forest (0.97 ± 0.18 m/s). Bees and wind are both pollen vectors of R. cephalotes, but bees were the pollen vector that contributed most to fruit set (63.3%) for individuals inside the forest, whereas wind was the primary vector for individuals at the forest edge (76.6%). This seesaw in importance of each pollen vector in the two different environments guarantees high fruit set in R. cephalotes under different microclimatic conditions.
