The influence of phosphatidylserine localisation and lipid phase on membrane remodelling by the ESCRT-II/ESCRT-III complex
Authors: Booth Andrew , Marklew Christopher J. , Ciani Barbara , Beales Paul A. 
Published: April 2020

AbstractThe endosomal sorting complex required for transport (ESCRT) organises in supramolecular structures on the surface of lipid bilayers to drive membrane invagination and scission of intraluminal vesicles (ILVs), a process also controlled by membrane mechanics. However, ESCRT association with the membrane is also mediated by electrostatic interactions with anionic phospholipids. Phospholipid distribution within natural biomembranes is inhomogeneous due to, for example, the formation of lipid rafts and curvature-driven lipid sorting. Here, we have used phase-separated giant unilamellar vesicles (GUVs) to investigate the link between phosphatidylserine (PS)-rich lipid domains and ESCRT activity. We employ GUVs composed of phase separating lipid mixtures, where unsaturated DOPS and saturated DPPS lipids are incorporated individually or simultaneously to enhance PS localisation in liquid disordered (Ld) and/or liquid ordered (Lo) domains, respectively. PS partitioning between the coexisting phases is confirmed by a fluorescent Annexin V probe. Ultimately, we find that ILV generation promoted by ESCRTs is significantly enhanced when PS lipids localise within Lddomains. However, the ILVs that form are rich in Lolipids. We interpret this surprising observation as preferential recruitment of the Lophase beneath the ESCRT complex due to its increased rigidity, where the Ldphase is favoured in the neck of the resultant buds to facilitate the high membrane curvature in these regions of the membrane during the ILV formation process. Lddomains offer lower resistance to membrane bending, demonstrating a mechanism by which the composition and mechanics of membranes can be coupled to regulate the location and efficiency of ESCRT activity.

Authors: Zhang Anan , He Jiahui , Lin Yu , Li Qian , Yang Wei , Qu Guanglong 
Published: April 2020

Purpose
Considering the problem that the high recognition rate of deep learning requires the support of mass data, this study aims to propose an insulating fault identification method based on small data set convolutional neural network (CNN).

Design/methodology/approach
Because of the chaotic characteristics of partial discharge (PD) signals, the equivalent transformation of the PD signal of unit power frequency period is carried out by phase space reconstruction to derive the chaotic features. At the same time, geometric, fractal, entropy and time domain features are extracted to increase the volume of feature data. Finally, the combined features are constructed and imported into CNN to complete PD recognition.

Findings
The results of the case study show that the proposed method can realize the PD recognition of small data set and make up for the shortcomings of the methods based on CNN. Also, the 1-CNN built in this paper has better recognition performance for four typical insulation faults of cable accessories. The recognition performance is improved by 4.37% and 1.25%, respectively, compared with similar methods based on support vector machine and BPNN.

Originality/value
In this paper, a method of insulation fault recognition based on CNN with small data set is proposed, which can solve the difficulty to realize insulation fault recognition of cable accessories and deep data mining because of insufficient measure data.

Authors: Taneo Stefanus Yufra M. , Hadiwidjojo Djumilah , Sunaryo Sunaryo , Sudjatno Sudjatno 
Published: April 2020

Purpose
This study aims to examine the role of creative destruction and knowledge creation which is a mediation between the speed of innovation and the competitiveness of food small- and medium-sized enterprises (SMEs). Creative destruction and the creation of competency-based and market-based knowledge are usually carried out by companies in power to create barriers to entry and expand distance with similar businesses, so the role of creative destruction and knowledge creation as mediation to strengthen competitiveness is investigated.

Design/methodology/approach
The data in this study were collected from 161 UKM which are the population of food UKM in Malang, covering three regions, namely, Malang City, Malang Regency and Batu City. Warp Partial Least Square-Structural Equation Modeling (WarpPLS-SEM) has greater statistical requirements than other covariance-based methods, which are more likely to give results that are in accordance with the conditions of the population (significant if it is actually significant in the population) so that it is very efficient.

Findings
It is very important for the pace of innovation development to improve the competitiveness of food SMEs. Innovation ideas are quickly realized and products that enter the market faster have greater opportunities to increase competitiveness through profits and productivity. The pace of innovation development increases the competitiveness of food SMEs. This study proves that competitiveness can be increased once the pace of innovation development is followed by creative destruction and knowledge creation. In this case, creative destruction is done through increased competence and maintain the innovations that have been achieved by food SMEs. Increasing business competence can be done through cost efficiency, improving product quality and improving worker skills. This is done while maintaining innovation achieved to strengthen market networks, customer service and innovation in product packaging. The basis of organizational learning is knowledge creation; this point is missing in organizational learning theories. The focus here is on the creation of knowledge as a process, a missing factor in theories about learning organizations.

Research limitations/implications
This study has limitations that this study analyzes processed foods and innovations in general. Future research should investigate one type of processed food based on an innovation typology so that it can provide more effective and efficient recommendations.

Originality/value
To the best of the authors’ knowledge, this is the first known analysis of innovation speed and creative destruction for SMEs of food sector.
How social entrepreneurs’ attention allocation and ambidextrous behavior enable hybrid organization
Authors: Zheng Wenzhi , Bronson James , Lin Chunpei 
Published: April 2020

PurposeThis paper aims to explore the social entrepreneurs’ attention allocation and their resource action that lead to hybrid organization using the paradox theory. Paradox theory deepens understandings of the varied nature, dynamics and outcomes of entrepreneurial tensions. This study explores the systematic effects of internal and external attention on both economic and social performance.Design/methodology/approachFirst, theoretically, hypotheses linking different attention allocations to ambidextrous behavior and entrepreneurial performance were formulated. Subsequently, the empirical studies based on Chinese social entrepreneurship were conducted to test the hypotheses.FindingsThe study provides support to the hypotheses showing that external attention is linked to resource acquisition and social performance, while internal attention is linked to resource acquisition and strategic human resource management and thus these ambidextrous behaviors promote both social and economic performance. Furthermore, normal pressure moderates the relations between internal attention and strategic human resource management only.Research limitations/implicationsThe research measures entrepreneurs’ attention with questionnaire rather than psych test. Also, static data rather than longitudinal research is designed to test the hypotheses.Practical implicationsDeeper understanding of the attention of social entrepreneurs and resource action can help entrepreneurial outcomes and can potentially contribute to paradox and tension management by entrepreneurial practitioners in China.Originality/valueSocial entrepreneurs’ different attention allocation and related entrepreneurial ambidextrous behavior processes are linked to paradoxical thinking for the first time. The findings of this research can potentially enhance social entrepreneurship paradoxical thinking aimed at preventing mission drift.

Why should I share knowledge with others? A review-based framework on events leading to knowledge hiding
Authors: Anand Amitabh , Centobelli Piera , Cerchione Roberto 
Published: April 2020

PurposeThe significance of managing and sharing employee knowledge for successful organizational change, innovation, and for sustainable advantage has indeed been suggested by research since the last few decades. Despite numerous attempts to foster the sharing of knowledge in organizations, employees may not always be willing to share knowledge attributed due to personal beliefs or situational constraints leading to hiding of knowledge. This article provides a theoretical basis by identifying and illustrating the present and the possible myriad of knowledge hiding (KH) events by employees within organizations.Design/methodology/approachDrawing literature from numerous sources, this paper adopts synthesis and provides a review of the literature and proposes framework.FindingsThis paper identifies six broad drivers which may lead to KH, including: driven by situation explain the reason for unintentional hiding as a result of performance and competition leads to individual to have a motive to hide knowledge, driven by psychological ownership leads to controlled hiding, driven by hostility and abuse by employees or managers leads to victimized hiding and lastly driven by identity and norms leads to favoured hiding. Furthermore, this study uncovers three potential future events, which need managerial attention: negative reciprocity, influenced disengagement and perceived disengagement.Originality/valueThis paper also offers new insights to managers to understand the present events and foresee the possible reasons about the KH behaviour and how they can strategize to reduce these events and undergo organizational change.

Authors: Yang Wenxiu , Li Lin , Wang Shuo , Liu Jinshu 
Published: April 2020

Purpose
The purpose of this paper is to fabricate a high-performance filtration electrospun nanofiber membrane with antibacterial function. The Ag nanoparticles (AgNPs) gotten by reducing AgNO3 act as antimicrobial agent. Then the AgNPs/Polyacrylonitrile (AgNPs/PAN) composite nanofiber membrane was prepared by electrospinning.

Design/methodology/approach
The electrospun Ag/PAN composite membrane was prepared by one step, in which the Ag particles were acting as antibacterial agent and PAN nanofiber as the upholder of the composite mat. AgNPs were obtained by reducing AgNO3 in N,N-Dimethylformamide (DMF) solution at high temperature. Meanwhile, the PAN particles were added to DMF solution and dissolved. Then the Ag/PAN nanofiber was obtained by electrospinning.

Findings
The thinner nanofiber can be produced with PAN concentration of 12 per cent and AgNPs concentration of 10 per cent. Finally, the filtration resistance of the composite membrane with antibacterial property is as high as 99.1 per cent, and the filtration efficiency is only 83 Pa. Therefore, the AgNPs/PAN composite membrane is the ideal choice for air filtration with antibacterial property.

Originality/value
The AgNPs/PAN composite nanofiber membrane has high filtration performance for particulate matter (PM)25 and outstanding antibacterial property to Escherichia coli and Staphylococcus aureus, which can be used with masks, air-conditioning filters (including car air-conditioning filters), window screening and other similar objects.
A CUSUM tool for retrospectively evaluating team performance: the case of the English Premier League
Authors: Beggs Clive , Bond Alexander John 
Published: April 2020

PurposeDespite being a widely used management technique, cumulative sum (CUSUM) analysis remains almost unheard of in professional sport. To address this, CUSUM analysis of soccer match data from the English Premier League (EPL) was performed. The primary objective of the study was to evaluate CUSUM as a tool for assessing “on-field” team performance. As a secondary objective, the association between managerial change and team performance was evaluated.Design/methodology/approachCUSUM was applied retrospectively to goal difference data for six EPL teams (Arsenal, Chelsea, Everton, Liverpool, Manchester United and Tottenham) over 23 consecutive seasons from 1995 to 2018. This was supplemented with change point analysis to identify structural changes in mean goal difference. Succession was evaluated by mapping historical managerial changes onto the CUSUM plots for the respective clubs.FindingsCUSUM analysis revealed the presence of structural changes in four clubs. Two structural change points were identified for both Chelsea and Everton, one for Manchester United and Tottenham and none for Arsenal and Liverpool. Relatively few managerial changes coincided temporally with structural changes in “on-field” performance, with most appointments having minimal impact on long-term team performance. Other factors (e.g. changes in ownership) appear to have been influential.Research limitations/implicationsThe study was limited by the fact that only successful teams were investigated.Practical implicationsCUSUM analysis appears to have potential as a tool for executive decision-makers to evaluate performance outcomes in professional soccer.Originality/valueThe study is the first of its kind to use CUSUM analysis to evaluate team performance in professional soccer.
