Authors: Hu Hao , Qi Fazhi , Zhang Hongmei , Tian Haolai , Luo Qi 
Published: December 2020

According to the estimated data rates, it is predicted that 24 PB raw experimental data will be produced per month from 14 beamlines at the first stage of the High-Energy Photon Source (HEPS) in China, and the volume of experimental data will be even greater with the completion of over 90 beamlines at the second stage in the future. To make sure that the huge amount of data collected at HEPS is accurate, available and accessible, an effective data management system (DMS) is crucial for deploying the IT systems. In this article, a DMS is designed for HEPS which is responsible for automating the organization, transfer, storage, distribution and sharing of the data produced from experiments. First, the general situation of HEPS is introduced. Second, the architecture and data flow of the HEPS DMS are described from the perspective of facility users and IT, and the key techniques implemented in this system are introduced. Finally, the progress and the effect of the DMS deployed as a testbed at beamline 1W1A of the Beijing Synchrotron Radiation Facility are shown.

It is expected that this will encourage quantity surveyors, procurement practitioners and their institutions to implement Six Sigma in addressing persistent delays in their competitive tendering processes.Originality/valueThis paper demonstrates the use of merged approach under mixed method to identify the benefits and challenges of Six Sigma implementation in construction competitive tendering process within the Ghanaian context.
Awakening the leadership anatomy in times of crisis
Authors: Yeo Roland K. 
Published: December 2020

Purpose
This paper explores the concept of leadership anatomy in a health crisis like Covid-19 as it relates our body parts to sensory connections that affect our response to uncertainty.

Design/methodology/approach
In-depth interviews were conducted with 25 leaders and a cross-section of 47 employees drawn from all six business units of a multinational professional service firm. Content analysis of the data led to key implications for leadership practice.

Findings
Leading through the anatomy results in a productive tension that awakens the inner voice, helping leaders think, feel, and act in more resilient ways.

Practical implications
Using leadership anatomy as an analogy, we suggest that leaders should learn to connect with their inner senses to develop systems thinking. Such is the ability to make sense of our chaotic surroundings in the way we think, feel, and act.

Originality/value
The significance of this study is the rare moments of leadership behavior captured in the midst of a pandemic that contribute to current debate and direction in leadership research and practice.
Bayesian experimental design for CO2 sequestration with leakage risk assessment
Authors: Dia Ben Mansour 
Published: December 2020

Purpose
The author examine the sequestration of CO2 in abandoned geological formations where leakages are permitted up to only a certain threshold to meet the international CO2 emissions standards. Technically, the author address a Bayesian experimental design problem to optimally mitigate uncertainties and to perform risk assessment on a CO2 sequestration model, where the parameters to be inferred are random subsurface properties while the quantity of interest is desired to be kept within safety margins.

Design/methodology/approach
The author start with a probabilistic formulation of learning the leak-age rate, and the author later relax it to a Bayesian experimental design of learning the formations geo-physical properties. The injection rate is the design parameter, and the learned properties are used to estimate the leakage rate by means of a nonlinear operator. The forward model governs a two-phase two-component flow in a porous medium with no solubility of CO2 in water. The Laplace approximation is combined with Monte Carlo sampling to estimate the expectation of the Kullback–Leibler divergence that stands for the objective function.

Findings
Different scenarios, of confining CO2 while measuring the risk of harmful leakages, are analyzed numerically. The efficiency of the inversion of the CO2 leakage rate improves with the injection rate as great improvements, in terms of the accuracy of the estimation of the formation properties, are noticed. However, this study shows that those results do not imply in any way that the learned value of the CO2 leakage should exhibit the same behavior. Also this study enhances the implementation of CO2 sequestrations by extending the duration given by the reservoir capacity, controlling the injection while the emissions remain in agreement with the international standards.

Originality/value
Uncertainty quantification of the reservoir properties is addressed. Nonlinear goal-oriented inverse problem, for the estimation of the leakage rate, is known to be very challenging. This study presents a relaxation of the probabilistic design of learning the leakage rate to the Bayesian experimental design of learning the reservoir geophysical properties.
Reading by listening: conceptualising audiobook practices in the age of streaming subscription services
Authors: Tattersall Wallin Elisa 
Published: December 2020

PurposeThe purpose of this paper is to clarify issues related to the contemporary study of audiobook practices, in order to aid subsequent research on topics related to reading, digital audiobooks and streaming subscription services.Design/methodology/approachUsing the concept of remediation, this paper covers four messy issues for audiobook researchers, primarily by developing the concept of reading by listening and then exploring the different remediations of the audiobook, clarifying the audiobook as a book and exploring the context of streaming subscription services.FindingsReading is here conceptualised according to the human sense used when making meaning from text, with reading by listening suggested for reading done with the help of the ears. Three different forms of remediation can be seen in subscription-based audiobooks, related to format, content and sense. Audiobooks simultaneously follow traditions of reading aloud, remediates the printed book and previous audiobook formats. It is suggested that the content is what makes an audiobook a book. The concepts library model and bookshop model are introduced to understand different audiobook subscription service models.Originality/valueThis is a research area on the rise with several messy issues and the concepts and clarifications in this paper may benefit future research.
Governmental accounting reforms at a time of crisis: the Italian governmental accounting harmonization
Authors: Mussari Riccardo , Cepiku Denita , Sorrentino Daniela 
Published: December 2020

PurposeAcknowledging fiscal crises as critical junctures for policy makers, this paper investigates how the recent fiscal crisis has affected the paradigmatic approach to the design of an ongoing governmental accounting (GA) reform.Design/methodology/approachThis paper analyses the Italian GA harmonization as a peculiar instance of an ongoing GA reform at the crisis outbreak. A longitudinal narrative analysis of official documents is complemented with semi-structured interviews with key policy makers and participant observations.FindingsThe fiscal crisis is found to play an indirect role in the Italian GA reform, which, promoting centralization of competencies in the fields of GA, determines the intensification of the approach adopted before the crisis outbreak.Research limitations/implicationsThis paper extends the knowledge on the nature of post-crisis reforms by highlighting how fiscal crises can work as catalysts for paradigmatic approaches to ongoing GA reforms. This paper analyses the designing of a GA reform, whereas the long-term adaptations and outcomes of the reform are not taken into consideration.Practical implicationsThe tight link between GA and financial management issues featuring the current paradigmatic approaches to reforms suggests the need to design GA reforms consistently with fiscal and financial management policies.Originality/valueWhereas the extant literature on the nature of post-crisis reforms analyses the latter as responses to the former, this paper enlarges the knowledge on the topic by focusing on a peculiar instance of a GA reform that was ongoing at the crisis outbreak.

Published: December 2020

PurposeThe study aims to investigate the academic libraries' response to the coronavirus disease 2019 (COVID-19) pandemic situation in Nigeria.Design/methodology/approachA survey research design was employed for the study. The population of the study was all the 584 approved academic institutions in Nigeria. A structured questionnaire administered online was designed to collect data with Google Form from heads of library (who are the chief principal officer) in all the academic institutions. The link to the survey was sent to the Nigeria Library Association (NLA) Online Forum, the platform on which Nigerian librarians fete and discuss issues relating to the profession. Social media tools such as WhatsApp and Telegram belonging to groups of academic librarians in Nigeria were also employed. The heads of the library from 108 academic libraries responded to the survey. The data generated were analyzed using a statistical tool and presented in tables.FindingsThe finding reveals that nearly all the students are not on campus since they have been directed to vacate their campus as a result of the lockdown. The study reveals some safety measures that were put in place by the libraries in Nigeria to include total closure of the library (59.3%), provision of hand sanitizer (55.6%) and the use of face mask and nose covers by library users (31.9%). The finding further indicates social distancing measures also put in place to include communication done via social media (59.3%), attendance to patrons (51.9%), class/lecture (51.9%), training/conferences (37%) and paper presentations (37%) that are all canceled, respectively. On access to library materials, a majority (87.96%) of the academic libraries in Nigeria provide only online materials to their users, while 9.26% of the academic libraries provide access to both prints and online materials.Research limitations/implicationsThe paper will contribute to the body of literature on academic libraries' response to the COVID-19 pandemic in Nigeria and beyond.Practical implicationsWhile the disease is still very much with the world, libraries have to continue providing information resources in support of the research studies and sensitize the world on the measures to take to curtail the pandemic.Originality/valueThe results can help other libraries find ways and means to adjust services, so that they can still meet the needs of users in this pandemic.
Understanding virtual reality continuance: an extended perspective of perceived value
Authors: Yang Heetae , Han Sang-Yeal 
Published: December 2020

PurposeThe purpose of this paper is to develop an integrated research model that can explain current users' continuance intention regarding the adoption of virtual reality (VR).Design/methodology/approachThis study builds a new research model based on the perceived value theory. The model and the hypotheses formulated are tested using partial least squares analysis with 295 respondents.FindingsBoth utilitarian value and hedonic value have positive impacts on VR users' continuance intention. Among the four constructs reflecting VR device and service-related attributes, content quality and ease of use have significant impacts on the utilitarian value and hedonic value. Visual attractiveness is positively associated with hedonic value while portability affected only utilitarian value.Practical implicationsTo increase users' retention of VR, VR service providers should focus developing high-quality VR content, and VR device manufacturers should consider both ease of use and visual attractiveness of VR devices.Originality/valueThis study is the first empirical study to investigate user adoption of VR devices and services synthetically, as most of prior studies related to VR adoption mainly focused on VR devices or specific services.

Authors: Fallah Mohammad Ali , Heidari Ali 
Published: December 2020

Purpose
This study aims to review the existing literature on corporate-level strategy to develop a conceptual framework of the headquarters’ roles as well as situational factors influencing them.

Design/methodology/approach
The systematic review is conducted. Accordingly, 598 studies (published from 1962–2018) were extracted from three databases (ProQuest, EBSCO and Web of Science). Then, after screening and ensuring the quality by the TAPUPAS checklist, 53 articles were systematically analyzed by manual coding method.

Findings
In total, 31 interventions in the form of four roles, namely, “value creation,” “value reduction,” “portfolio management“ and “loss prevent“ were identified for headquarters (HQ). Furthermore, four influencing situational factors distinguish “business characteristics,” “headquarters characteristics,” “corporate company characteristics” and “characteristic of the HQ-subsidiary relationships.”

Originality/value
The value of this research can be outlined as: mapping the cutting edge on the topic and systematizes the current knowledge; presenting an integrative, unique conceptual framework of HQs’ roles and influences, and particularly, of situational factors that determine the consequents of the interventions; and producing practical insights for corporate parent managers considering the situational factors influencing HQs’ roles and influences in managing their business portfolio successfully.
Bioenergy landscapes drive trophic shifts in generalist ants

Published: December 2020

Abstract

Changes in trophic niche—the pathways through which an organism obtains energy and nutrients—are a fundamental way in which organisms respond to environmental conditions. But the capacity for species to alter their trophic niches in response to global change, and the ways they do so when able, remain largely unknown.

Here we examine food webs in three long‐term and large‐scale experiments to test how resource availability and nutritional requirements interact to determine an organism's trophic niche in the context of one of the largest global trends in land use—the rise in bioenergy production.

We use carbon and nitrogen stable isotope analyses to characterize arthropod food webs across three biofuel crops representing a gradient in plant resource richness (corn monocultures, fields dominated by native switchgrass and restored prairie), and to quantify changes in the trophic niche of a widespread generalist ant species across habitats. In doing so, we measure the effects of basal resource richness on food chain length, niche breadth and trophic position. We frame our results in the context of two hypotheses that explain variation in trophic niche—the niche variation hypothesis which emphasizes the importance of resource diversity and ecological opportunity, and the optimal diet hypothesis which emphasizes dietary constraints and the availability of optimal resources.

Increasing plant richness lengthened food chains by 10%–20% compared to monocultures. Niche breadths of generalist ants did not vary with resource richness, suggesting they were limited by optimal diet requirements and constraints rather than by ecological opportunity. The ants instead responded to changes in plant richness by shifting their estimated trophic position. In resource‐poor monocultures, the ants were top predators, sharing a trophic position with predatory spiders. In resource‐rich environments, in contrast, the ants were omnivores, relying on a mix of animal prey and plant‐based resources.

In addition to highlighting novel ecosystem impacts of alternate bioenergy landscapes, our results suggest that niche breadth and trophic diversification depend more on the presence of optimal resources than on ecological opportunity alone.

Abstract

Tropical savannas are known for the fire‐prone ecosystems, yet, riparian evergreen forests are another important landscape feature. These forests usually remain safe from wildfires in the wet riparian zones. With global changes, large wildfires are now more frequent in savanna landscapes, exposing riparian forests to unprecedented impact.

In 2017, a large wildfire spread across the Chapada dos Veadeiros National Park, an iconic UNESCO site in central Brazil, raising concerns about its impact on the fire‐sensitive ecosystems. By combining remote sensing analysis of Google Earth images (2003–2019) with detailed field information from 36 sites, we assessed wildfire impacts on riparian forests. For this, we measured the structure of trees, saplings and herbaceous plants, as well as topsoil variables.

Since 2003, all riparian forests had canopy cover above 90%, but after 2017, canopy cover dropped to 20% in some forests, indicating large variation in wildfire damage. A closer look in the field revealed that, on average, the wildfire killed 52% of adult trees and 87% of tree saplings in flooded forests. In non‐flooded forests, impacts on adult trees were negligible, but fire killed 75% of tree saplings. Opportunistic vines and the invasive grass Melinis minutiflora were already present in severely disturbed flooded forests. In all forests, impacts on many ecosystem variables were related to canopy damage, a variable measurable from satellite. Overall, seasonally flooded riparian forests were the most severely impacted, possibly due to the relatively thinner barks of their trees.

Synthesis and applications. Our findings reveal how riparian forests embedded in tropical savanna landscapes are in danger from large wildfires. The destruction of some forests has opened space for new plant species that may propel a shift to an alternative ecosystem state. Riparian forests are habitat of large savanna animals and their loss could affect entire trophic networks. Managing wildfires and invasive grasses locally is probably the best strategy to maintain riparian forests resilient. As wildfire regimes intensify in tropical savanna landscapes, our findings stress the need for an integrated management that considers riparian forests as a vulnerable element of the system.

SummaryPseudomonas chlororaphis PCL1606 (PcPCL1606) displays plant‐colonizing features and exhibits antagonistic traits against soil‐borne phytopathogenic fungi. Biofilm formation could be relevant for the PcPCL1606 lifestyle, and in this study the role of some putative extracellular matrix components (EMC; Fap‐like fibre, alginate and Psl‐like polysaccharides) in the biofilm architecture and biocontrol activity of this bacterium were determined. EMC such as the Fap‐like fibre and alginate polysaccharide play secondary roles in biofilm formation in PcPCL1606, because they are not fundamental to its biofilm architecture in flow cell chamber, but synergistically they have shown to favour bacterial competition during biofilm formation. Conversely, studies on Psl‐like polysaccharide have revealed that it may contain mannose, and that it is strongly involved in the PcPCL1606 biofilm architecture and niche competition. Furthermore, the Fap‐like fibre and Psl‐like exopolysaccharide play roles in early surface attachment and contribute to biocontrol activity against the white root rot disease caused by Rosellinia necatrix in avocado plants. These results constitute the first report regarding the study of the extracellular matrix of the PcPCL1606 strain and highlight the importance of a putative Fap‐like fibre and Psl‐like exopolysaccharide produced by PcPCL1606 in the biofilm formation process and interactions with the host plant root.
