Published: January 2023

AbstractShrubs are used for revegetation of degraded dryland ecosystem worldwide and could recruit large numbers of microbes from the soil; however, the plant-associated microbiome assembly and the effect of plant introduction on the soil microbiomes are not fully understood. We detected shrub-associated microbes from five ecological microhabitats, including the leaves, litter, roots, rhizosphere, and root zone, across four xeric shrub plantations (Artemisia ordosica, Caragana korshinskii, Hedysarum mongolicum, andSalix psammophila). To detect the patterns of shrub-associated microbiome assembly, 16S and ITS2 rRNA gene sequencing was performed. PERMANOVA and differential abundance analysis demonstrated that changes in the bacterial and fungal communities were more dependent on the microhabitats rather than on the plant species, with distinct niche differentiation. Moreover, source tracking and nestedness analysis showed that shrub-associated bacteria were primarily derived from bulk soils and slightly pruned in different microhabitats; however, a similar pattern was not found for fungi. Furthermore, the surrounding zone of roots was a hotpot for microbial recruitments of revegetated shrubs. Null model analysis indicated that homogeneous selection of determinism dominated the bacterial communities, whereas dispersal limitation and undominated process of stochasticity drove the assembly of fungal communities. Our findings indicate that ecological microhabitat of revegetated shrublands was the main predictor of the bacterial and fungal compositional variances. This study will help advance our understanding of the mechanism underlying the plant-soil microbiome feedbacks during the initial plant-establishment period in a dryland ecosystem. Further, this work provides theoretical reference for establishment and sustainable management of shrublands in drylands.
Higher-order implicit shock-capturing scheme based on linearization of implicit fluxes for the Euler equations
Authors: Mittakolu Roshith , Rani Sarma L. , Sundaram Dilip Srinivas 
Published: January 2023

Purpose
A higher-order implicit shock-capturing scheme is presented for the Euler equations based on time linearization of the implicit flux vector rather than the residual vector.

Design/methodology/approach
The flux vector is linearized through a truncated Taylor-series expansion whose leading-order implicit term is an inner product of the flux Jacobian and the vector of differences between the current and previous time step values of conserved variables. The implicit conserved-variable difference vector is evaluated at cell faces by using the reconstructed states at the left and right sides of a cell face and projecting the difference between the left and right states onto the right eigenvectors. Flux linearization also facilitates the construction of implicit schemes with higher-order spatial accuracy (up to third order in the present study). To enhance the diagonal dominance of the coefficient matrix and thereby increase the implicitness of the scheme, wave strengths at cell faces are expressed as the inner product of the inverse of the right eigenvector matrix and the difference in the right and left reconstructed states at a cell face.

Findings
The accuracy of the implicit algorithm at Courant–Friedrichs–Lewy (CFL) numbers greater than unity is demonstrated for a number of test cases comprising one-dimensional (1-D) Sod’s shock tube, quasi 1-D steady flow through a converging-diverging nozzle, and two-dimensional (2-D) supersonic flow over a compression corner and an expansion corner.

Practical implications
The algorithm has the advantage that it does not entail spatial derivatives of flux Jacobian so that the implicit flux can be readily evaluated using Roe’s approximate Jacobian. As a result, this approach readily facilitates the construction of implicit schemes with high-order spatial accuracy such as Roe-MUSCL.

Originality/value
A novel finite-volume-based higher-order implicit shock-capturing scheme was developed that uses time linearization of fluxes at cell interfaces.
Going solo and feeling smart? An exploratory study on shoppers' time valuation and cultural perception
Authors: Wang Xueqin , Wong Yiik Diew , Yuen Kum Fai 
Published: January 2023

PurposeThe advent of digitalization and the trend of social distancing coincide with the individualized lifestyle that is emerging among contemporary shoppers. This study explores the unique market of “smart solo shoppers”. Two empirical studies are conducted, which aim to identify the major dimensions of multi-channel shopping activities that are engaged by the shoppers (Study 1, n = 64) and to differentiate the shoppers' valuation of time invested in the distinct dimensions under different cultural influences (Study 2, n = 519).Design/methodology/approachA survey questionnaire is used for data collection, and data are analyzed using structural equation modeling.FindingsResults reveal that the shopping activities converge into four principal dimensions: offline shopping, online shopping, post-shopping delivery and product return activities. Shoppers who perceive offline shopping activities as a time burden and online shopping and delivery activities as venues of value creation are more strongly self-identified as smart solo shoppers. Furthermore, smart solo shoppers who are under a strong influence of individualistic culture are found to spend time on multi-channel shopping to make the right purchase the first time, whereas shoppers perceiving being in a weak individualistic culture prefer to engage online channels while being prepared to return the unwanted purchases.Originality/valueThis study highlights an emerging research field in the nexus of solo consumption and smart shopping. Emphasizing the utility-driven and ego-expressive nature of smart solo shoppers, the authors provide an initial profile of these shoppers based on their time-valuation patterns and the contextual impacts of individualistic culture.
Mapping research activities and societal impact by taxonomy of indicators: uniformity and diversity across academic fields
Authors: Lykke Marianne , Amstrup Louise , Hvidtfeldt Rolf , Pedersen David Budtz 
Published: January 2023

PurposeSeveral frameworks have been developed to map and document scientific societal interaction and impact, each reflecting the specific forms of impact and interaction that characterize different academic fields. The ReAct taxonomy was developed to register data about “productive interactions” and provide an overview of research activities within the social sciences and humanities (SSH). The purpose of the present research is to examine whether the SSH-oriented taxonomy is relevant to the science, technology, engineering and mathematics (STEM) disciplines when clarifying societal interactions and impact, and whether the taxonomy adds value to the traditional STEM impact indicators such as citation scores and H-index.Design/methodology/approachThe research question was investigated through qualitative interviews with nine STEM researchers. During the interviews, the ReAct taxonomy and visual research profiles based on the ReAct categories were used to encourage and ensure in-depth discussions. The visual research profiles were based on publicly available material on the research activities of the interviewees.FindingsThe study provided an insight into how STEM researchers assessed the importance of mapping societal interactions as a background for describing research impact, including which indicators are useful for expressing societal relevance and impact. With regard to the differences between STEM and SSH, the study identified a high degree of cohesion and uniformity in the importance of indicators. Differences were more closely related to the purpose of mapping and impact assessment than between scientific fields. The importance of amalgamation and synergy between academic and societal activities was also emphasised and clarified.Practical implicationsThe findings highlight the importance of mapping societal activities and impact, and that societal indicators should be seen as inspiring guidelines depending on purpose and use. A significant contribution is the identification of both uniformity and diversity between the main fields of SSH and STEM, as well as the connection between the choice of indicators and the purpose of mapping, e.g. for impact measurement, profiling, or career development.Originality/valueThe work sheds light on STEM researchers' views on research mapping, visualisation and impact assessment, including similarities and differences between STEM and SSH research.
Functionality and usability features of ubiquitous mobile technologies: the acceptance of interactive travel apps
Authors: Camilleri Mark Anthony , Troise Ciro , Kozak Metin 
Published: January 2023

Purpose
Customers are increasingly using mobile applications (apps) to compare prices of travel and hospitality services and to purchase their itineraries, tours and stays. This study aims to explore key factors affecting the individuals’ perceptions on the usefulness of travel apps and sheds light on the causal paths predicting the individuals’ dispositions to use them.

Design/methodology/approach
Quantitative data was gathered from 1,320 research participants, who were members of popular social media groups. They were analyzed through a composite-based partial least squares approach.

Findings
The results confirm that information quality, source credibility and the functionality of travel apps are significantly affecting the individuals’ perceptions about their usefulness as well as their intentions to continue using them in future. They also indicate that there are highly significant indirect effects within the information technology adoption model.

Research limitations/implications
This study integrates the information quality and source credibility factors from the information adoption model (IAM) with a functionality construct that was drawn from electronic service quality. This study examines their effects on the technology acceptance model (TAM)’s perceived usefulness and behavioral intentions.

Practical implications
This research implies that there is scope for the travel service providers to enhance the quality and functionality of their mobile apps to improve their consumers’ perceptions about the utilitarian value of these ubiquitous technologies.

Originality/value
This contribution raises awareness on the importance of incorporating a functionality construct in addition to IAM and/or TAM “usability” factors to better understand the individuals’ dispositions to avail themselves of online content and/or to adopt interactive innovations. In this case, it implies that certain functionality features of travel apps, including their responsiveness and technical capabilities, can trigger users to increase their engagement with these mobile technologies on a habitual basis.
Perceptions about Corporate Ethical Behaviour in the Founders’ Country of Origin and Ventures’ Admission into Impact‐Oriented Accelerator Programmes: Cross‐Country Evidence
Authors: Gaganis Chrysovalantis , Papadimitri Panagiota , Pasiouras Fotios , Tasiou Menelaos 
Published: January 2023

AbstractBuilding on the upper echelon and signalling theories, we hypothesize that perceptions about the corporate ethical behaviour in the country of origin of a venture's founders may provide an important piece of information to the selection committees of impact‐oriented accelerator programmes that serves as a signal for the trustworthiness and opportunistic behaviour of the founding team. In turn, this could have implications for the decision regarding admission into a programme. Using a sample of over 16,000 early‐stage ventures from 131 countries that applied to 287 accelerator programmes, we find evidence consistent with this hypothesis. Our results show that better perceptions about the ethical behaviour of the founding team enhance the likelihood of admission into an impact‐oriented accelerator programme. The role of perceived ethics appears to be stronger in the case of programmes that guarantee some kind of financing. Further analysis shows that the strength of both formal and informal institutions moderates the relationship between the ethical perceptions and the admission likelihood.
Characterizing the effect of sodium reduction and monosodium glutamate supplementation on white and multigrain breads
Authors: Dunteman Aubrey N. , Lee Soo‐Yeun 
Published: January 2023

AbstractSodium overconsumption has become a serious health concern resulting in the Food and Drug Administration (FDA) publishing voluntary sodium reduction guidelines for a wide spectrum of packaged and processed foods. Reducing sodium through the removal of salt may decrease the palatability of foods, thus increasing the need for new approaches to prevent such palatability loss. The objective of this research was to characterize white and multigrain breads with either 43% or 60% reduction in sodium and with and without monosodium glutamate (MSG) using descriptive analysis methodology as well as to identify the drivers of liking for white and multigrain breads of varying sodium contents with and without MSG. Significant differences were identified in the attributes of salty taste and aftertaste, savory aftertaste, and chewy and firm textures in white bread and of salty taste and aftertaste, sweet taste, and density in multigrain bread. By regressing consumer test data of these breads onto their principal component analysis biplots, textural attributes and salty taste and aftertaste were identified as primary drivers of liking in white and multigrain breads. Flavor enhancers such as MSG show promise in mitigating palatability loss that occurs when the sodium content of bread is greatly reduced and thus provide a promising solution to produce breads with an improved nutritional profile. Future research on flavor enhancement in other food matrices would be valuable as well as in other bread and carbohydrate‐based food categories.Practical ApplicationThe findings of our study suggest that texture and a salty taste and aftertaste drive consumer liking of reduced‐sodium white and multigrain breads and liking of breads could be improved with the addition of monosodium glutamate. Increasing the acceptance of reduced‐sodium food products could help to improve the health of the American population by resulting in a reduced risk of hypertension and subsequently heart attacks and stroke.
Exhumation and Preservation of the Jinchuan Ni‐Cu‐PGE Deposit under the East Longshou Mountain Thermal Evolution, Revealed by Apatite Fission Track Thermochronology

Published: January 2023

AbstractUplift and exhumation are important factors affecting the preservation of deposits. The anatomy of uplift‐cooling evolution and exhumation in the East Longshou Mountain is of significant research value in understanding changes in the Jinchuan Ni‐Cu‐PGE deposit since its formation. This study uses apatite fission track (AFT) thermochronology to reconstruct the thermal history of the East Longshou Mountain, including the Jinchuan mine, revealing the uplift and exhumation history of the East Longshou Mountain and elucidating the preservation status of the Jinchuan deposit. The AFT ages in the East Longshou Mountain are distributed from 62.3 ± 3.0 Ma to 214.7 ± 14 Ma, with significant differences in ages in distinct areas, the central and pooled ages being consistent within the margin of error. Inverse thermal history models reveal two rapid cooling events associated with exhumation from the Early Jurassic to the Early Cretaceous (200–100 Ma) and since the Miocene (15–0 Ma), the former attributable to the far‐afield response to the closure of the Paleo‐Tethys Ocean and plate assembly at the southern margin of Eurasia, the latter associated with the initial India‐Eurasia plate collision. A slow cooling event from the Early Cretaceous to the Miocene (100–15 Ma) is thought to be related to the arid environment in northwest China since the Cretaceous. These cooling events have diverse responses and cooling rates in different blocks of the East Longshou Mountain: the southwest and centre of which are mainly cooled over 200–120 Ma and 120–0 Ma, with cooling rates of ~0.25 and ~0.33 °C/Ma (~1.25 and ~0.33 °C/Ma in the centre); the Jinchuan mine primarily cooled over 160–100 Ma, 100–15 Ma and 15–0 Ma, with cooling rates of ~1.33, ~0.25 and ~2.00 °C/Ma. These differentiated coolings imply that the uplift of the East Longshou Mountain before the Miocene (~15 Ma) was integral. Strong uplift then occurred in the vicinity of the mining area, which is a critical period for the uplift of the Jinchuan deposit to the surface, meaning that the Jinchuan deposit was exposed no earlier than the Miocene (~15 Ma). Based on mineralization depth information obtained by previous researchers, in conjunction with the calculation and simulation results of this study, it can be seen that the bulk of the Jinchuan intrusion may still be preserved at depth.
The variant senescence‐associated secretory phenotype induced by centrosome amplification constitutes a pathway that activates hypoxia‐inducible factor‐1α

Published: January 2023

AbstractThe senescence‐associated secretory phenotype (SASP) can promote paracrine invasion while suppressing tumour growth, thus generating complex phenotypic outcomes. Likewise, centrosome amplification can induce proliferation arrest yet also facilitate tumour invasion. However, the eventual fate of cells with centrosome amplification remains elusive. Here, we report that centrosome amplification induces a variant of SASP, which constitutes a pathway activating paracrine invasion. The centrosome amplification‐induced SASP is non‐canonical as it lacks the archetypal detectable DNA damage and prominent NF‐κB activation, but involves Rac activation and production of reactive oxygen species. Consequently, it induces hypoxia‐inducible factor 1α and associated genes, including pro‐migratory factors such as ANGPTL4. Of note, cellular senescence can either induce tumourigenesis through paracrine signalling or conversely suppress tumourigenesis through p53 induction. By analogy, centrosome amplification‐induced SASP may therefore be one reason why extra centrosomes promote malignancy in some experimental models but are neutral in others.
Economic impact of giving land to refugees

Published: January 2023

AbstractThis paper adds to a sparse but growing literature on the economic costs and benefits of hosting refugees, including a unique policy of providing refugees with access to cultivable land. We construct a general equilibrium model from microsurvey data to simulate the spillover effects of giving land to refugees on income and production in the host‐country economy surrounding a refugee settlement in Uganda. Reduced‐form econometric analysis of land allocations at the refugee settlement, robust to several specifications, confirms the simulation finding that providing refugees with agricultural land significantly improves their welfare and self‐reliance. Simulations reveal that refugee aid and land allocations generate positive income spillovers in the local economy out to a 15‐km radius around the refugee settlement. Host‐country households benefit significantly from the income spillovers that refugee assistance creates, and host‐country agriculture is the largest beneficiary among production sectors.
Does circadian dysrhythmia drive the switch into high‐ or low‐activation states in bipolar I disorder?

Published: January 2023

AbstractObjectivesEmerging evidence suggests a role of circadian dysrhythmia in the switch between “activation” states (i.e., objective motor activity and subjective energy) in bipolar I disorder.MethodsWe examined the evidence with respect to four relevant questions: (1) Are natural or environmental exposures that can disrupt circadian rhythms also related to the switch into high‐/low‐activation states? (2) Are circadian dysrhythmias (e.g., altered rest/activity rhythms) associated with the switch into activation states in bipolar disorder? (3) Do interventions that affect the circadian system also affect activation states? (4) Are associations between circadian dysrhythmias and activation states influenced by other “third” factors?ResultsFactors that naturally or experimentally alter circadian rhythms (e.g., light exposure) have been shown to relate to activation states; however future studies need to measure circadian rhythms contemporaneously with these natural/experimental factors. Actigraphic measures of circadian dysrhythmias are associated prospectively with the switch into high‐ or low‐activation states, and more studies are needed to establish the most relevant prognostic actigraphy metrics in bipolar disorder. Interventions that can affect the circadian system (e.g., light therapy, lithium) can also reduce the switch into high‐/low‐activation states. Whether circadian rhythms mediate these clinical effects is an unknown but valuable question. The influence of age, sex, and other confounders on these associations needs to be better characterised.ConclusionBased on the reviewed evidence, our view is that circadian dysrhythmia is a plausible driver of transitions into high‐ and low‐activation states and deserves prioritisation in research in bipolar disorders.
Mitigating the effects of climate change on the nests of sea turtles with artificial irrigation
Authors: Gatto Christopher R. , Williamson Sean A. , Reina Richard D. 
Published: January 2023

AbstractFor sea turtles, like many oviparous species, increasing temperatures during development threaten to increase embryonic mortality, alter offspring quality, and potentially create suboptimal primary sex ratios. Various methods are being implemented to mitigate the effects of climate change on reproductive success, but these methods, such as breeding programs, translocations, and shading, are often invasive and expensive. Irrigation is an alternative strategy for cooling nests that, depending on location, can be implemented relatively quickly and cheaply. However, multiple factors, including ambient conditions, nest substrate, and species characteristics, can influence irrigation success. Additionally, irrigation can vary in duration, frequency, and the volume of water applied to nests, which influences the cooling achieved and embryonic survival. Thus, it is critical to understand how to maximize cooling and manage risks before implementing irrigation as a nest‐cooling strategy. We reviewed the literature on nest irrigation to examine whether artificial irrigation is feasible as a population management tool. Key factors that affected cooling were the volume of water applied and the frequency of applications. Embryonic responses varied with species, ambient conditions, and the timing of irrigation during development. Nest inundation was the key risk to a successful irrigation regime. Future irrigation regimes must identify clear targets, either primary or adult sex ratios, that maximize population viability. Monitoring population responses and adjusting the irrigation regime in response to population characteristics will be critical. Most studies reported on the manipulation of only one or two variables, further research is required to understand how altering multiple factors in an irrigation regime influences the cooling achieved and embryonic responses.
