Authors: Hashemi Ali , Cai Chang , Kutyniok Gitta , Müller Klaus-Robert , Nagarajan Srikantan S. , Haufe Stefan 
Published: August 2020

AbstractMethods for electro- or magnetoencephalography (EEG/MEG) based brain source imaging (BSI) using sparse Bayesian learning (SBL) have been demonstrated to achieve excellent performance in situations with low numbers of distinct active sources, such as event-related designs. This paper extends the theory and practice of SBL in three important ways. First, we reformulate three existing SBL algorithms under themajorization-minimization(MM) framework. This unification perspective not only provides a useful theoretical framework for comparing different algorithms in terms of their convergence behavior, but also provides a principled recipe for constructing novel algorithms with specific properties by designing appropriate bounds of the Bayesian marginal likelihood function. Second, building on the MM principle, we propose a novel method calledLowSNR-BSIthat achieves favorable source reconstruction performance in low signal-to-noise-ratio (SNR) settings. Third, precise knowledge of the noise level is a crucial requirement for accurate source reconstruction. Here we present a novel principled technique to accurately learn the noise variance from the data either jointly within the source reconstruction procedure or using one of two proposed cross-validation strategies. Empirically, we could show that the monotonous convergence behavior predicted from MM theory is confirmed in numerical experiments. Using simulations, we further demonstrate the advantage of LowSNR-BSI over conventional SBL in low-SNR regimes, and the advantage of learned noise levels over estimates derived from baseline data. To demonstrate the usefulness of our novel approach, we show neurophysiologically plausible source reconstructions on averaged auditory evoked potential data.

Published: August 2020

AbstractPredators drive top-down effects that shape prey communities, but the role of predators in dispersing prey microbiomes is rarely examined. We tested whether coral-eating (corallivorous) fish disperse the single-celled dinoflagellate symbionts (family Symbiodiniaceae) of their prey. Our findings demonstrate that: (1) coral-eating fish egest feces containing live Symbiodiniaceae at densities up to seven orders of magnitude higher than other environmental reservoirs such as sediments and water; (2) Symbiodiniaceae communities in the feces of most corallivores are compositionally similar to those in corals; (3) some obligate corallivore species release over 100 million Symbiodiniaceae cells per 100 m2per day; and (4) after being egested, corallivore feces often come in direct contact with coral colonies (potential hosts for Symbiodiniaceae). These findings suggest that fish predators can play an important role in symbiont acquisition by corals; such predators may have a previously unrecognized, indirect positive effect on prey health.

Published: August 2020

AbstractWe deeply sequenced two pairs of widely used infectious clones (4 plasmids) of the bipartite begomoviruses African cassava mosaic virus (ACMV) and East African cassava mosaic Cameroon virus (EACMCV). The sequences of the ACMV clones were quite divergent from our expectations. We have made raw reads, consensus plasmid sequences, and the infectious clones themselves publicly available.
Data Integration with SUMO Detects Latent Relationships Between Patients in Lower-Grade Gliomas

Published: August 2020

AbstractJoint analysis of multiple genomic data types can facilitate the discovery of complex mechanisms of biological processes and genetic diseases. We present a novel data integration framework based on non-negative matrix factorization that uses patient similarity networks. Our implementation supports continuous multi-omic datasets for molecular subtyping and handles missing data without using imputation, making it more efficient for genome-wide assays in large cohorts.Applying our approach to gene expression, microRNA expression, and methylation data from patients with lower grade gliomas, we identify a subtype with a significantly poorer prognosis. Tumors assigned to this subtype are hypomethylated genome-wide with a gain of AP-1 occupancy in the demethylated distal enhancers. These tumors’ genomic profiles are similar to Grade IV gliomas: they are enriched for somatic chr7 gain, chr10 loss, and other molecular events that have yet to be used in the diagnosis of lower-grade gliomas as per the current WHO guidelines.
Two modes of PRC1-mediated mechanical resistance to kinesin-driven microtubule network disruption
Authors: Alfieri April , Gaska Ignas , Forth Scott 
Published: August 2020

AbstractThe proper structural organization of the microtubule-based spindle during cell division requires the collective activity of many different types of proteins. These include non-motor microtubule-associated proteins (MAPs) whose functions include crosslinking microtubules to regulate filament sliding rates and assembling microtubule arrays. One such protein is PRC1, an essential MAP that has been shown to preferentially crosslink overlapping antiparallel microtubules at the spindle midzone. PRC1 has been proposed to act as a molecular brake, but insight into the mechanism of how PRC1 molecules function cooperatively to resist motor-driven microtubule sliding and to allow for the formation of stable midzone overlaps has been lacking. Here we employ a modified microtubule gliding assay to rupture PRC1-mediated microtubule pairs using surface-bound kinesins. We discovered that PRC1 crosslinks always reduce bundled filament sliding velocities relative to single microtubule gliding rates, and do so via two distinct emergent modes of mechanical resistance to motor-driven sliding. We term these behaviors braking and coasting, where braking events exhibit substantially slowed microtubule sliding compared to coasting events. Strikingly, braking behavior requires the formation of two distinct high-density clusters of PRC1 molecules near microtubule tips. Our results suggest a cooperative mechanism for PRC1 accumulation when under mechanical load that leads to a unique state of enhanced resistance to filament sliding and provides insight into collective protein ensemble behavior in regulating the mechanics of spindle assembly.
International accounting standards in French companies in the 1990s: an institutionalization contested by US GAAP
Authors: Touron Philippe , Daly Peter 
Published: August 2020

PurposeThe paper analyzes four cases of IAS adoption (Aérospatiale in 1989; Usinor in 1991; Coflexip in 1993; and Péchiney in 1995) to better understand the instructional logics behind the use of alternative or additional standards by French companies in the early 1990s.Design/methodology/approachThe study employs multiple case studies to explain how and why the heterogeneity of adoption (IAS versus US GAAP) is a response to institutional complexity.FindingsThis research shows that French companies adopted IAS as long as they were not required to use US GAAP by their financial backers. The results highlight how the companies combine logics to respond to the complexification of the field. The authors outline how endorsement of logics by outside carriers (auditors, financial analysts, stock exchange commissions) and framing of logics by managers evolve in time and space within this complexification process.Research limitations/implicationsThis study contributes to the institutional complexity literature in that it focuses on distinct organizational responses to multiple institutional logics. More precisely, the choice of standards in primary consolidated accounts are viewed as an organizational response to compatible and conflicting demands from several levels: home countries, transnational areas and host countries with the aim of raising funds in the US.Originality/valueThis research makes a distinct link between institutional complexity and international accounting standards and US GAAP.
Re-visiting traditional trust measurement: using artefactual field experiments to measure trust and predict micro-lending decisions
Authors: Buck Steven , Kusunose Yoko , Alwang Jeffrey 
Published: August 2020

PurposeThe purpose of this work is to experimentally measure trust and study its relationship to group loan allocation within a community bank.Design/methodology/approachAn artefactual field experiment is run to capture a measure of trust that mimics aspects of trusting behavior in a community bank. The experimental design and empirical setting take into account risk and altruism, two known confounders of trust measures. Regression analysis is used to estimate the relationship between a novel measure of trust and the loan amount a borrower receives from their rural community bank.FindingsThe trust measure has a statistically significant, positive relationship with loan size. A one standard deviation increase in the trust measure corresponds to a 13.3 percent increase in the loan amount.Social implicationsResults of the study suggest that, for community banks, trust in a borrower plays a large role in screening applicants and therefore determining loan size. Several such banks have considered graduating to commercial credit. However, given the outsize role of trust in lending decisions, it is not clear if commercial lending models – which rely less on social capital – will work.Originality/valueA new trust game is developed that captures relationship-specific measures of directed trust that community bank members have towards each borrower. The trust measure is also context-specific as play in the game is analogous to how community bank members trust some borrowers (more than others) with larger loans. The emphasis on relationship- and context-specific trust measures is key to interpreting results from artefactual field experiments.
Learning disability, autism and the Criminal Procedure (Scotland) Act
Authors: Williams Fionnuala , Warwick Mike , McKay Colin , Macleod Callum , Connolly Moira 
Published: August 2020

Purpose
This paper aims to investigate the use of Part VI of the Criminal Procedure (Scotland) Act 1995 (CPSA) for people with Learning Disability (LD) and/or Autism. This is in the context of a recent review commissioned by the Scottish Government into whether the provisions in the Mental Health (Care and Treatment) (Scotland) Act 2003 (MHA) meet the needs of these groups which would also affect associated legislation such as CPSA.

Design/methodology/approach
All CPSA orders active on the 3 January 2018 were identified and analysed for a number of variables including diagnoses, detention length, level of hospital security and medication use.

Findings
Of the 580 people on CPSA orders, 69 (11.9%) had LD and 27 (4.7%) had possible/definite Autism. Most people with LD (56.5%) did not have a mental illness or personality disorder. Most (81.2%) had mild LD. There were two patients whose only diagnosis was Autism. Mean duration of detention was longer for those with LD than for those without. Most patients with LD alone were prescribed medication (61.5%) and, if in hospital, were managed in low secure units (59%).

Originality/value
The results indicate that people with LD or Autism are differently affected by the application of the CPSA from other people with mental disorders, and that this is potentially discriminatory, if it is not objectively justified . It supports the stance from the recent review that to reduce the potential for discrimination, substantial changes to MHA and CPSA should be considered in the wider review of the MHA in Scotland.
Information security frameworks for assisting GDPR compliance in banking industry
Authors: Serrado João , Pereira Ruben Filipe , Mira da Silva Miguel , Scalabrin Bianchi Isaías 
Published: August 2020

Purpose
Data can nowadays be seen as the main asset of organizations and data leaks have a considerable impact on the organization’s image, revenues and possible consequences to the affected clients. One of the most critical industries is the bank. Information security frameworks (ISF) have been created to assist organizations and other frameworks evolved to update these domain practices. Recently, the European Union decided to create the general data protection regulation (GDPR), applicable to all organizations dealing with personal data of citizens residing in the European Union. Although considered a general regulation, GDPR implementation needs to align with some industries’ laws and policies. Especially in the Bank industry. How these ISF can assist the implementation of GDPR is not clear.

Design/methodology/approach
The design science research process was followed and semi-structured interviews performed.

Findings
A list of practices to assist the bank industry in GDPR implementation is provided. How each practice map with assessed ISF and GDPR requirements is also presented.

Research limitations/implications
As GDPR is a relatively recent subject, it is hard to find experts in the area. It is more difficult if the authors intend to find experienced people in the GDPR and bank industry. That is one of the main reasons this study does not include more interviews.

Originality/value
This research provides a novel artefact to the body of knowledge. The proposed artefact lists which ISF practices banks should implement to comply with GDPR. By doing it the artefact provides a centralized view about which ISF frameworks (or part of them) could be implemented to help banks comply with GDPR.
Use and social value in peer-to-peer prosumption communities
Authors: Alhashem Mohammed , Moraes Caroline , Szmigin Isabelle T. 
Published: August 2020

Purpose
This paper aims to examine how prosumption manifests in an online community, Instructables.com, and its value for those who engage with it. The paper emphasizes its distinctiveness compared to similar phenomena, particularly co-creation.

Design/methodology/approach
This work uses a netnography-informed research approach, involving Instructables community observations, participation and 15 online interviews with members of the community.

Findings
Prosumption provides personal benefits including hedonic elements of enjoyment and fun, functional elements of monetary saving and self-sufficiency, and cognitive benefits such as problem solving and learning. Further, extra-personal benefits include community-, environment-, market-, family- and friends-oriented benefits.

Research limitations/implications
Personal and extra-personal prosumption benefits generate use and social value, progressing understanding of value through a type of prosumption that the authors term peer-to-peer.

Practical implications
An understanding of the differences among concepts can set expectations, responsibilities and opportunities for both firms and prosumers in an increasingly collaborative marketplace.

Originality/value
By critically analyzing the nature of value through a particular kind of prosumption, the paper makes three theoretical contributions. First, it transforms and broadens the scope of empirical research by clarifying critical distinctions between co-creation and prosumption and establishing them as higher-order concepts. Second, the paper determines the benefits, use and social value participants derive from particular forms of participation in the marketplace. Finally, the paper establishes a new concept, namely peer-to-peer prosumption, which the authors define as a type of prosumption that prioritizes collective, peer-to-peer use and social value over exchange value. The paper contributes to marketing literature on the ongoing evolution of consumer roles and participation in the marketplace, by furthering theorization in this field.
An analysis of growth-accelerating factors for the Indian automotive industry using modified TISM
Authors: Meena Abhilasha , Dhir Sanjay , Sushil  
Published: August 2020

PurposeThis study aims to identify and prioritize various growth-accelerating factors in the Indian automotive industry. It further develops a hierarchical model to examine the mutual interactions between the factors, their dependence and their driving power.Design/methodology/approachThis study first identifies the growth-accelerating factors and then uses the modified total interpretive structural modeling (m-TISM) framework, which is an extended version of TISM. It further uses MICMAC analysis to analyze the mutual interrelation between the identified factors.FindingsThis study highlights the interrelation amongst the factors using m-TISM model. A hierarchical model shows the level of autonomous, dependence, linkage and independent factors considering the Indian automotive industry. This study also provides the understanding related to the interdependence of growth-accelerating factors.Research limitations/implicationsThe government and practitioners could evaluate the growth-accelerating factors which have higher driving power for implementing efficient policies and strategy formulation. By implementing m-TISM model in the Indian automotive industry, auto manufacturers can become more productive and profitable. Future studies could use other methods such as expert opinion to derive the factors, and further model could be verified using structural equation modeling technique.Originality/valueThis study uses a novel m-TISM framework for the analysis of growth-accelerating factors in the context of the Indian automotive industry. It further provides a detailed theoretical and conceptual understanding relating to the philosophy and establishes an interrelation amongst these under-researched growth-accelerating factors.
Linking ISO 9000 certification to firm performance and financial crisis: a matched sample longitudinal analysis
Authors: Siougle Efrosini , Dimelis Sophia 
Published: August 2020

PurposeThis is a longitudinal study exploring the effect of ISO 9000 certification on firm's financial performance in the pre-crisis period and the 2008 financial crisis period.Design/methodology/approachThe empirical analysis is based on a 22-year dataset with balance sheet data from 136 Greek listed firms covering the period 1992–2013. A matching technique is applied to properly estimate potential differences in the impact of ISO 9000 on firm's financial performance between the groups of certified and matched non-certified (control) firms in the entire period but, most importantly, in pre-crisis vs crisis periods, using the difference-in-differences econometric approach.FindingsThe findings indicate that certified firms exhibit significantly higher financial performance relative to the matched non-certified group in both the pre-crisis and crisis periods, which tends to persist for several years post-certification. The financial crisis has a negative and statistically significant effect on firm performance in both the certified and matched non-certified groups, which nevertheless did not differ significantly between them. Controlling for sectoral and technological differences did not harm the higher performance of certified firms relative to the matched control peers. The results remain in the same direction when the authors test the ISO 9000 effect in the sub-group of certified firms that obtained the certification at the firm-level.Originality/valueThe study is original in its sample design and hypothesis testing. The matched sample created from a sufficiently long and continuous time dataset enabled the authors to properly estimate firm performance differences of ISO 9000 between pre-crisis and crisis periods. Of additional value is the testing of sectoral/technological differences and the distinction between firm-level and plant-level certification.
Image congruence between sports event and host city and its impact on attitude and behavior intention
Authors: Zhang Yinghui , Kim Euisoo , Xing Zunming 
Published: August 2020

PurposeImage congruence is one central metrics that significantly influences image transfer. Nevertheless, studies on impact of image congruence on consumers' attitudinal and behavioral components in the context of sport tourism remain few. Therefore, this study aims to investigate the relationship among image congruence between sport event and host city, spectators' attitude toward the event and city and their intention to revisit and recommend the event and city. A mediating role of attitude in the relationship between image congruence and behavioral intention was also examined.Design/methodology/approachThe study selected non-local spectators of the F1 Chinese Grand Prix and Shanghai ATP Masters 1000 as the participants. A total of 491 valid questionnaires were obtained from the survey of two events, including 222 from F1 Chinese Grand Prix and 269 from Shanghai ATP Masters 1000. Among respondents, 360 were Chinese spectators from other regions (73.3%) and 131 were international spectators (26.7%). The data were analyzed via descriptive statistics, correlations, factor analysis, exploratory factor analysis (EFA), confirmatory factor analysis (CFA), hierarchical regression analysis and ANOVA.FindingsThe results showed that image congruence between sports event and host city had a positive impact on spectators' attitude toward and intention to recommend the city; but it had no significant impact on attitude toward event, intention to revisit and recommend the event and intention to revisit the city. Attitude toward event had a positive impact on intention to revisit and recommend the event, and attitude toward host city had a positive impact on intention to revisit and recommend the city. In addition, attitude toward host city fully mediated the relationship between image congruence and intention to recommend the city.Originality/valueThe current study provides a meaningful contribution to the existing literature by examining the impact of image congruence on spectators' attitudinal and behavioral components in the context of sport tourism.

Purpose
This concept paper aims to discuss the effects of network hospitality on women empowerment in the city of Kuala Lumpur.

Design/methodology/approach
This paper uses a qualitative approach to analyse women engaged in Airbnb activity as hosts or guests.

Findings
Findings show new types of entrepreneurs, hospitality services, and socio-cultural expectations under this change.

Originality/value
The recent growth of Network Hospitality platforms such as Airbnb around the world has generated multiple impacts on urban destinations worldwide. Network hospitality is transforming the way tourism is produced and consumed. Several studies have analysed the impact of network hospitality on destinations’ accommodation and housing markets, the gentrification effects and users’ experience. However, studies on the social impacts of Airbnb in developing economies remain scarce. Network hospitality is creating entrepreneurship and mobility opportunities for women. In the case of Malaysia, there is a noticeable empowerment trend of women through network hospitality.
