AbstractThe COVID19 pandemic is likely to cause more than a million of deaths worldwide, primarily due to complications from COVID19-associated acute respiratory distress syndrome (ARDS). Controversy surrounds the circulating cytokine/chemokine profile of COVID19-associated ARDS, with some groups suggesting that it is similar to non-COVID19 ARDS patients and others observing substantial differences. Moreover, while a hyperinflammatory phenotype associates with higher mortality in non-COVID19 ARDS, there is little information on the inflammatory landscape’s association with mortality in COVID19 ARDS patients. Even though the circulating leukocytes’ transcriptomic signature has been associated with distinct phenotypes and outcomes in critical illness including ARDS, it is unclear whether the mortality-associated inflammatory mediators from COVID19 patients are transcriptionally regulated in the leukocyte compartment. Here, we conducted a prospective cohort study of 41 mechanically ventilated patients with COVID19 infection using highly calibrated methods to define the levels of plasma cytokines/chemokines and their gene expressions in circulating leukocytes. Plasma IL1RA and IL8 were found positively associated with mortality while RANTES and EGF negatively associated with that outcome. However, the leukocyte gene expression of these proteins had no statistically significant correlation with mortality. These data suggest a unique inflammatory signature associated with severe COVID19.
Could self-centrism rust the glitter of meaningful work? Exploring the darker sides of the construct
Authors: Pattnaik Subhra , Jena Lalatendu Kesari 
Published: May 2020

Purpose
The paper explores if individuals experiencing deeply meaningful work turn self-centric and therein they negatively affect people around them. It also discusses ways to attenuate this darker effect of meaningful work.

Design/methodology/approach
Semi-structured interviews were conducted with supervisors, peers, subordinates, and family of 24 executives in the Indian Aeronautical Manufacturing Sector who scored high on the Meaningful Work scale in another empirical study carried out by the authors in early 2019.

Findings
Individuals experiencing deeply Meaningful Work get self-centric, at times, where nothing beyond work appeals to them. This negatively affects their camaraderie at work and family ties.

Originality/value
The paper adds to the scarce literature on the darker side of Meaningful Work by exploring its effect on breeding self-centrism using an Indian sample.
Direct modifications of tetrahedral meshes
Authors: Guo YuFei , Hai YongQing , Liu JianFei 
Published: May 2020

Purpose
During the industrial design process, a product is usually modified and analyzed repeatedly until reaching the final design. Modifying the model and regenerating a mesh for every update during this process is very time consuming. To improve efficiency, it is necessary to circumvent the computer-aided design modeling stage when possible and directly modify the meshes to save valuable time. The purpose of this paper is to develop a method for mesh modifications.

Design/methodology/approach
In contrast to existing studies, which focus on one or a class of modifications, this paper comprehensively studies mesh union, mesh gluing, mesh cutting and mesh partitioning. To improve the efficiency of the method, the paper presents a fast and effective surface mesh remeshing algorithm based on a ball-packing method and controls the remeshing regions with a size field.

Findings
Examples and results show that the proposed mesh modification method is efficient and effective. The proposed method can be also applied to meshes with different material properties, which is very different with previous work that is only suitable for the meshes with same material property.

Originality/value
This paper proposes an efficient and comprehensive tetrahedral mesh modification method, through which engineers can directly modify meshes instead of models and save time.
Why digital goods have not replaced traditional goods: the case of e-books
Authors: Kim Jongbum , Seo Jeonghun , Zo Hangjung , Lee Hwansoo 
Published: May 2020

PurposeElectronic books (e-books) have been in the market for decades but have been unable to replace paper books. Previous studies on e-books have failed to identify significant factors affecting the adoption and diffusion of e-books. This study develops a theoretical framework to explain the adoption behavior of e-books from the perspective of user resistance.Design/methodology/approachAfter a pilot test with 50 e-book users, the research model is validated using a partial least squares structural equation modeling (PLS-SEM) technique. A web-based survey method is used to collect data from a sample of 350 people – selected from Korean e-book users and nonusers – during a week in March 2017. This study tests the reliability and validity of the integrated model of planned behavior and resistance theory and tests the hypotheses with bootstrapping resampling.FindingsThe results show that four barriers – usage, value, risk and image – cause resistance to change and users with higher resistance have lower intention to use. The moderating effect of self-efficacy between resistance to change and intention to use is confirmed. Self-efficacy interacts not only with the encouraging factors but also with resistance.Originality/valueThis study expands the understanding of users' adoption behavior of e-books by examining inhibiting factors using a novel integrated model. The findings of this research provide insights for digital product providers, especially e-book publishers, to understand why digital products have not been successful in the marketplace.
The role of the family council and protocol in planning the succession process in family firms
Authors: Matias Cláudia , Franco Mário 
Published: May 2020

PurposeThe main objective of this study is to understand the role that family council and protocol can have in the planning process of family companies.Design/methodology/approachTo reach this general objective, the qualitative approach was used using multiple case studies: seven Portuguese family companies. Data collection techniques, interviewing, direct observation and documentary analysis were used.FindingsBased on the empirical evidence, it is concluded that the family council and family protocol help succession planning and favour the continuity and survival of the family business. However, other working groups also support the entire planning process, such as the cousin generation meeting and the New Generation Monitoring Committee (or Mentoring Committee). The development of future personal plans for the younger generations may lie in this Committee, which assists and guides the younger family members.Practical implicationsThis study is pioneering in Portugal because it analyses the use of new instruments that helps the succession planning process in family firm context: the family council and family protocol. These managerial mechanisms allow to achieve the success, allowing family conflicts to be minimized, the continuity of family firms and avoiding their mortality.Originality/valueThe study contributes to increasing knowledge about the family council, the family protocol, family firm succession and its planning. It is important and innovative by studying those topics in depth, their connection being little explored in the literature. This study can be seen as a benchmarking for governance practices in other countries.
The antecedents of Muslim customers’ intention to invest in an Islamic bank’s term deposits: evidence from a Muslim majority country
Authors: Hati Sri Rahayu Hijrah , Wibowo Sigit Sulistiyo , Safira Anya 
Published: May 2020

Purpose
The purpose of this study is to examine the impacts of product knowledge, perceived quality, perceived risk and perceived value on customers’ intention to invest in Islamic Banks. This study specifically examines an Islamic bank’s term deposits.

Design/methodology/approach
Structural equation modeling was used to analyze the data collected from 217 customers of an Islamic bank in Indonesia using an online survey.

Findings
This study highlights the central and dual roles of perceived risk as both the independent and the intervening variable that mediates the relationship between product knowledge and Muslim customer intention to invest in an Islamic bank’s term deposits.

Research limitations/implications
This study only investigates term deposits as one type of investment in Islamic banks. This study contributes to the literature by examining the role of product knowledge, perceived quality, perceived risk and perceived value on Muslim customer intention to invest in Islamic term deposits.

Practical implications
The results of this study highlight the requirement for Islamic banks to educate customers to improve the depositors’ product knowledge because Muslim customers’ risk and value perception and intention are strongly influenced by product knowledge.

Originality/value
The investigation of perceived risk is particularly relevant for Islamic financial products because of the inherent nature of risk sharing in Islamic finance. This study investigates the role of product knowledge in influencing the Muslim customers’ perception of risk, quality, value and their intention to invest in Islamic bank term deposits. Ideally, the profit loss sharing concept (PLS) should be applied; however, in this context, revenue sharing is applied because of Indonesia’s central bank regulation.
Electronic procurement adoption, usage and performance: a literature review
Authors: Nandankar Sunil , Sachan Amit 
Published: May 2020

Purpose
Despite the substantial research in the domain of electronic procurement adoption, usage and performance (EP AUP), there is no structured review of these studies and most of the literature is in fragmented form. Therefore, the purpose of this paper is to investigate and synthesize EP AUP research in the past two decades and map key research approaches, prevailing theories and antecedents used by researchers to study EP AUP at the individual user and organizational level.

Design/methodology/approach
To evaluate and comprehend past and current patterns/themes in the EP AUP research area, a systematic literature review is undertaken. Significant peer-reviewed studies covering three categories – adoption, usage and performance and seven classification criteria are critically reviewed.

Findings
The findings reveal that most investigators mainly used “technology acceptance model,” “technology–organization–environment” framework and their extensions, demonstrating that “perceived ease of use,” “perceived usefulness,” “trust,” “organizational size,” “organizational readiness” and “behavioral intentions” are the most critical drivers of EP AUP.

Research limitations/implications
For researchers and practitioners, the review highlights a taxonomy of contextual factors to be considered for successful EP AUP. It further makes suggestions for future research meeting challenges of Industry-4.0.

Originality/value
To the best of the authors’ knowledge, this is the first systematic literature review undertaken in the field of EP that studies it from three different perspectives. It further builds on the determinants of EP AUP and classifies them in four distinct categories: organizational, individual, information system level and environmental.

Published: May 2020

PurposeResearch has been conducted to analyze the landslide in Banaran area, Ponorogo Regency. The landslides occurred on April 1, 2017. This study was conducted to know the subsurface conditions in the Banaran area to analyze the disaster mitigation efforts. The mitigation efforts are made to reduce the risk from landslides and possible landslides.Design/methodology/approachThe method used is the geo-electric resistivity method of Wenner–Schlumberger configuration. The research was conducted in three villages namely Banaran Village, Bekirang Village and Mendak Village.FindingsThere are 12 resistivity measuring points with a track length of 410 m and a space of 10 m. The measured resistivity range is between 1.42 Ω.m and 67.500 Ω.m. The resistivity data and the local geological maps interpreted that the rocks in the Banaran area consist of clay, tuff lapilli, volcanic breccia and andesite lava. The landslide area begins at a depth of 8–35 m below the surface which is interpreted as tuff. Also, the thickness of the landslide material and the slope is = 400 which supports the occurrence of a more prominent landslide. The results of the parameter scoring of the landslide-prone areas indicated that the research area is very vulnerable to a landslide. The results of the interpretation indicate that the geo-electric resistivity method can provide a good overview for conducting landslide analysis, that is field slippage and potential material thickness occurrence landslide.Originality/valueThis article is very specific as it attempts to discover how prone Banaran are is to landslide.
Testing the efficiency of metal's market: new evidence from a generalized spectral test
Authors: Pathak Rajesh , Gupta Ranjan Das , Taufemback Cleiton Guollo , Tiwari Aviral Kumar 
Published: May 2020

Purpose
This paper aims to examine the weak form of efficiency for price series of four precious metals, i.e. gold, silver, platinum and palladium, using a generalized spectral method.

Design/methodology/approach
The method has the advantage of detecting both linear and non-linear serial dependence in the conditional mean, and it is robust to various forms of conditional heteroscedasticity. The authors use three different rolling windows for the purpose of robustness.

Findings
The authors report weak form of efficiency across metals series for almost all rolling windows. The optimum efficiency for Gold and Palladium is achieved through 250 days rolling window estimates whereas it is 500 days rolling window for silver. Platinum has similar efficiency levels across rolling windows. The degree of efficiency for metal prices is observed to be varying over time with silver market possessing highest levels of efficiency. The efficiency synchronization also varies across rolling windows and metals.

Research limitations/implications
The results reveal that metal markets are efficient for most times implying the low predictability and the low likelihood of earning abnormal returns by speculating in these markets.

Originality/value
The study uses a relatively new statistical technique, the generalized spectral test, to capture linear and non-linear serial dependence. Therefore, the results possess adequate power against departure from market efficiency.
Applied nucleation facilitates tropical forest recovery: Lessons learned from a 15‐year study

Published: May 2020

Abstract

Applied nucleation, mostly based upon planting tree islands, has been proposed as a cost‐effective strategy to meet ambitious global forest and landscape restoration targets.

We review results from a 15‐year study, replicated at 15 sites in southern Costa Rica, that compares applied nucleation to natural regeneration and mixed‐species tree plantations as strategies to restore tropical forest. We have collected data on planted tree survival and growth, woody vegetation recruitment and structure, seed rain, litterfall, epiphytes, birds, bats and leaf litter arthropods.

Our results indicate that applied nucleation and plantation restoration strategies are similarly effective in enhancing the recovery of most floral and faunal groups, vegetation structure and ecosystem functions, as compared to natural regeneration.

Seed dispersal and woody recruitment are higher in applied nucleation and plantation than natural regeneration treatments; canopy cover has increased substantially in both natural regeneration and applied nucleation treatments; and mortality of planted N‐fixing tree species has increased in recent years. These trends have led to rapid changes in vegetation composition and structure and nutrient cycling.

The applied nucleation strategy is cheaper than mixed‐species tree plantations, but there may be social obstacles to implementing this technique in agricultural landscapes, such as perceptions that the land is not being used productively.

Applied nucleation is likely to be most effective in cases where: planted vegetation nuclei enhance seed dispersal and seedling establishment of other species; the spread of nuclei is not strongly inhibited by abiotic or biotic factors; and the approach is compatible with restoration goals and landowner preferences.

Synthesis and applications. Results from our 15‐year, multi‐site study show that applied nucleation can be a cost‐effective strategy for facilitating tropical forest regeneration that holds promise for helping to meet large‐scale international forest restoration commitments.
Integrating crop modelling and production economics to investigate multiple nutrient deficiencies and yield gaps

Published: May 2020

A method is described for integrating crop modelling and production economics to quantify optimum applications of multiple nutrients and yield gaps. The method is demonstrated for crop production in the high‐rainfall zone of southern Australia. Data from a biophysical crop model were used to overcome the persistent problem of inadequate experimental data. The Mitscherlich function was expanded to accommodate four variable inputs – nitrogen, phosphorus, potassium and sulphur – and the expansion path was used to determine the economic optimum application of all four nutrients. Modelling revealed the state‐contingent yield potential and the extent to which unrealised yield could be explained by profit‐maximising behaviour and risk‐aversion by growers. If growers and their advisors were guided by the methods described, they would be better equipped to assess crop nutrient demands and limitations, predict yield potential, additional profit and the risks associated with high input systems in a variable climate. If scientists were more aware of the extra profits and the risks involved (as well as the quantitative relationships between inputs and outputs) when thinking about what to produce and how to do so, they would be more circumspect about the net benefits to be obtained from closing yield gaps.
Disability Insurance: Theoretical Trade‐Offs and Empirical Evidence*
Authors: Low Hamish , Pistaferri Luigi 
Published: May 2020

AbstractDisability insurance provides protection against health shocks that limit the ability to work. In most countries, these programmes are large and growing, both in expenditure and in number of recipients. We discuss the traditional trade‐off between insurance and incentives in providing this insurance, with a focus on the US and UK experiences. There is substantial evidence on the extent of the labour supply incentive costs of disability insurance, but there has been a lack of evidence on the insurance value until very recently. Further, evidence on errors in the disability insurance process suggests false rejections of genuine claimants is a substantial problem, and these are more serious than false acceptances of healthy applicants. We provide a life‐cycle framework for understanding the trade‐offs and to evaluate the welfare implications of policy reforms. We argue that reforms should be focused on reducing false rejections and supporting labour market attachment. The difficulty in considering reform is that the design of disability insurance has many aspects that interact and impact on outcomes.
Cognitive and Non‐Cognitive Impacts of High‐Ability Peers in Early Years*
Authors: Belfield Christopher , Rasul Imran 
Published: May 2020

AbstractThe sorting of students into ability groups is one of the most common, controversial and long‐examined educational practices. Ability grouping also mechanically changes peer groups. We provide novel evidence on the cognitive and non‐cognitive impacts in early years, of being exposed to higher‐ability classroom peers through being assigned to the top within‐class ability group. We exploit panel data from the UK Millennium Cohort Study, which allows us to construct trajectories of the cognitive and non‐cognitive development of children from birth to entry into primary school. The data also record school grouping policies and the specific within‐class group assignment of each child, by subject. We combine these rich data with an instrumental variable design using child‐level variation in group assignment due to month of birth, in order to measure the local average treatment effect (LATE) of being assigned to the highest‐ability peer group. We find that if a marginal student is assigned higher‐ability peers, this significantly reduces their cognitive achievement in mathematics, and has no impact on literacy. There are countervailing impacts on non‐cognitive outcomes for the marginal student assigned higher‐ability peers: although they are more motivated to study and parents respond with an improved home learning environment, these children have more study‐related difficulties and their relations with their peers significantly worsen. These findings have important policy implications for the use and design of within‐class ability grouping in early years.
Balloon‐occluded retrograde transvenous obliteration (BRTO) of gastric varices using foam sclerosant and a reduced balloon inflation time: Feasibility and efficacy

Published: May 2020

AbstractIntroductionBalloon‐occluded retrograde transvenous obliteration (BRTO) is recommended for secondary prevention of gastric variceal bleeding in the American Association for the Study of Liver Disease (AASLD) guidelines, as an alternative to Transjugular intrahepatic portosystemic shunt (TIPS). However, there is significant heterogeneity in how BRTO is performed, including how and how long to occlude the outflow venous shunt amongst other variables such as variceal size, flow rate, agent used, and preparation technique. We propose a method using foam sclerotherapy and reducing balloon occlusion to as little as 30 min, with assessment of the efficacy of this shorter balloon inflation time.MethodsRetrospective single‐centre analysis of BRTO procedures between July 2015 and February 2019 for isolated gastric varices in a non‐acute setting, where inflation time was 2 h or less.ResultsSix patients underwent BRTO with a short inflation time, with a mean age of 66 years. The median balloon inflation and thus 3% athoxysclerol foam contact time was 30 min (range 30–60 min). Four of the 6 patients showed complete resolution of varices, while 2 of the 6 showed a partial response. Mean follow‐up was 27 months. There were no patients who did not show a response to treatment and no episodes of clinically significant upper gastrointestinal bleeding.ConclusionsThis technique using a shortened balloon occlusion time resulted in complete or partial clinical and technical success in all patients and suggests that the threshold for initiation of gastric variceal thrombosis may be below 30 min. This timepoint may provide a balance between adequate balloon inflation, angiography room efficiency and hospital resource allocation with resultant procedural cost implications.
