Published: April 2020

AbstractBacteria sense and respond to environmental stimuli through two-component systems (TCSs), that are composed of histidine kinase sensing and response regulator elements. TCSs are ubiquitous and participate in numerous cellular functions. TCSs across the ESKAPEE pathogens, representing the leading causes of nosocomial infections, were characterized using pangenome analytics, including annotation, mapping, pangenomic status, gene orientation, sequence variation, and structure. Our findings fall into two categories. 1) phylogenetic distribution of TCSs: (i) the number and types of TCSs varies between species of the ESKAPEE pathogens; (ii) TCSs are group-specific, i.e., Gram-positive and Gram-negative, except for KdpDE; (iii) most TCSs are conserved among genomes of an ESKAPEE, except inPseudomonas aeruginosa. 2) sequence variation: (i) at the operon level, the genomic architecture of a TCS operon stratifies into a few discrete classes; and (ii) at the gene sequence level, histidine kinases, responsible for signal sensing, show sequence and structural variability as compared to response regulators that show a high degree of conservation. Taken together, this first comprehensive pangenomic assessment of TCSs reveals a range of strategies deployed by the ESKAPEE pathogens to manifest pathogenicity and antibiotic resistance. It further suggests that the conserved features of TCSs makes them an attractive group of potential targets with which to address antibiotic resistance.

Published: April 2020

ABSTRACTUnder changing environmental conditions, salt stress has posed a severe threat to agriculture. Although the R40 family lectins are known to be associated with osmotic stress response, their mechanism of action remains elusive. Among them,Osr40g3displays the highest expression under salt stress. Here, we report that the constitutive overexpression ofOsr40g3imparts salt tolerance but displays pollen sterility and poor seed development in rice. Promoter analysis and gene expression studies revealed that the gene follows a precise tissue-specific expression pattern, which is essential for proper seed development. Overexpressing the gene under the control of its native promoter rescued the pollen-sterile phenotype while significantly improving salt tolerance. Protein-protein interaction studies demonstrated thatOsr40g3 positively regulates an expansin protein,OsEG45, while decreasing the stability of a 14-3-3 protein,OsGF14e. Correspondingly, theOsEG45overexpression andOsGF14esilencing lines display a salt-tolerant phenotype. Again, silencingOsEG45in the background ofOsGF14esilencing lines resulted in a salt-sensitive phenotype, indicating that salt tolerance of theOsGF14esilencing lines isOsEG45-dependent. Notably, theOsGF14egene displays early salt responsiveness, whileOsr40g3andOsEG45display a late response, indicating a spatio-temporal regulation of these genes. Interestingly, constitutive overexpression ofOsr40g3or silencing ofOsGF14eleads to diminished gibberellic acid (GA) accumulation that activates theOsEG45gene. Together, our study demonstrates that during salt stress,Osr40g3, a late salt-responsive gene, confers salt tolerance by negatively regulatingOsGF14e while positively regulatingOsEG45 via a GA-mediated pathway. This mechanistic insight broadens our understanding of lectin-mediated regulation of salt tolerance.
Institutional logics and institutional work: radical reform of the Chinese public accounting profession in the 1990s
Authors: Yee Helen 
Published: April 2020

PurposeThis paper examines radical reform of the Chinese public accounting profession in the 1990s. In particular, the paper seeks to provide a more nuanced understanding of the sources, responses and processes of this radical institutional change that effectively paved the way for development of the Chinese accounting profession into the twenty-first century.Design/methodology/approachThe empirical data that inform this study come from both archival materials (mostly in Chinese) and in-depth interviews. These data are analysed and interpreted from a neo-institutionalist perspective, drawing, in particular, on the concept of institutional logics and the concept of institutional work.FindingsA state logic initially guided the development of the Chinese accounting profession but was seriously challenged in the 1990s following a series of high profile financial scandals. The findings reveal a shift to a new professional logic, which was made possible through multiple forms of institutional works instigated by various state actors.Originality/valueResearch into the radical reform of the Chinese public accounting profession in the 1990s was mostly quantitative in nature, focussing mainly on one reform programme, i.e. the disaffiliation of the accounting firms from their sponsoring agencies. This paper adopts a qualitative approach and is aimed at providing a deeper and more nuanced understanding of the institutional change process within its political and economic contexts.
Monopolistic professional closure, family credentials and examination procedures in the Venetian college of accountants (16th−17th century)
Authors: Sargiacomo Massimo , Corsi Christian , D'Amico Luciano , Di Cimbrini Tiziana , Sangster Alan 
Published: April 2020

PurposeThe paper investigates the closure mechanisms and strategies of exclusion concerning the establishment and subsequent functioning of the Collegio dei Rasonati, the professional body of accountants that was established in Venice in 1581 and operated until the end of the 18th century.Design/methodology/approachThe research design offers a critical longitudinal explanation of the emergence of the Collegio dei Rasonati as a professional body in the context of Venetian society by relying on the social closure theory elaborated by Collins (1975); Parkin (1979) and Murphy (1988).FindingseThe Collegio dei Rasonati was established to overcome the prerogatives of a social class in accessing the accounting profession. However, the pre-existing professional elites enacted a set of social closure strategies able to transform this professional body into a stronghold of their privileges.Research limitations/implicationsAs virtually all of the evidence concerning the admission examinations has been lost over time, the investigation is restricted to the study of the few examples that have survived. The main implication of the study concerns the understanding of some dynamics leading to neutralize attempts to replace class privileges with a meritocratic system.Originality/valueThe research investigates the structure of the rules of social closure revealing the possibility of an antagonistic relationship between different co-existing forms of exclusion within the same structure. Moreover, it highlights that a form of exclusion can be made of different hierarchical levels.
Reconfiguration of assembly line balancing–an automobile case study solved by the exact solution procedure
Authors: Yadav Ashish , Kumar Shashank , Agrawal Sunil 
Published: April 2020

PurposeMulti-manned assembly lines are designed to produce large-sized products, such as automobiles. In this paper, a multi-manned assembly line balancing problem (MALBP) is addressed in which a group of workers simultaneously performs different tasks on a workstation. The key idea in this work is to improve the workstation efficiency and worker efficiency of an automobile plant by minimizing the number of workstations, the number of workers, and the cycle time of the MALBP.Design/methodology/approachA mixed-integer programming formulation for the problem is proposed. The proposed model is solved with benchmark test problems mentioned in research papers. The automobile case study problem is solved in three steps. In the first step, the authors find the task time of all major tasks. The problem is solved in the second step with the objective of minimizing the cycle time for the sub-tasks and major tasks, respectively. In the third step, the output results obtained from the second step are used to minimize the number of workstations using Lingo 16 solver.FindingsThe experimental results of the automobile case study show that there is a large improvement in workstation efficiency and worker efficiency of the plant in terms of reduction in the number of workstations and workers; the number of workstations reduced by 24% with a cycle time of 240 s. The reduced number of workstations led to a reduction in the number of workers (32% reduction) working on that assembly line.Practical implicationsFor assembly line practitioners, the results of the study can be beneficial where the manufacturer is required to increased workstation efficiency and worker efficiency and reduce resource requirement and save space for assembling the products.Originality/valueThis paper is the first to apply a multi-manned assembly line balancing approach in real life problem by considering the case study of an automobile plant.

Published: April 2020

PurposeThe paper takes stock of accumulated knowledge on factors impacting the success of online crowdfunding (CF) campaigns while suggesting opportunities for future research development.Design/methodology/approachA Systematic Literature Review of 88 academic papers published between 2010 and 2017. Papers were collected from four academic databases and published in 65 different journals. The review addresses issues related to theory, methods, context, findings and gaps. Overall, the paper presents an analysis of 1,718 associations between 111 aggregated independent variables (from 927 variables) with six main aggregated success indicators.FindingsMost research involves quantitative analyses of public data collected from reward-CF platforms. More research is required in equity, lending, donation and other CF contexts. Existing studies are mostly anchored in theories of signaling, social capital and elaboration likelihood. There is a need for wider conceptualization of success beyond financial indicators. And based on aggregated summaries of effects, the paper suggests a series of CF success models, while outlining an agenda for future research.Research limitations/implicationsStudied phenomenon is in its early days of existence, and hence biased by the circumstances of a new industry. Moreover, the current review only covers published journal articles in English.Practical implicationsFindings of factors impacting campaign success can inform fundraisers in building campaigns, as well as platforms in adjusting systems and services toward responsibly enhancing campaign success. Moreover, identified gaps can inform on what has not been sufficiently documented and may be a source of competitive advantage.Originality/valueA comprehensive review of research on CF success factors at factor level, a coherent agenda for future research development and a series of evidence-based models on most prevalent factors impacting CF success by CF model.
Physics-aware macromodels for MEMS switches
Authors: Lup Aurel-Sorin , Ciuprina Gabriela , Ioan Daniel , Duca Anton , Nicoloiu Alexandra , Vasilache Dan 
Published: April 2020

Purpose
The purpose of this paper is to propose a physics-aware algorithm to obtain radio frequency (RF)-reduced models of micro-electromechanical systems (MEMS) switches and show how, together with multiphysics macromodels, they can be realized as circuits that include both lumped and distributed parameters.

Design/methodology/approach
The macromodels are extracted with a robust procedure from the solution of Maxwell’s equations with electromagnetic circuit element (ECE) boundary conditions. The reduced model is extracted from the simulations of three electromagnetic field problems, in full-wave regime, that correspond to three configurations: signal lines alone, switch in the up and down positions.

Findings
The technique is exemplified for shunt switches, but it can be extended for lateral switches. Moreover, the algorithm is able take frequency dependence into account both for the signal lines and for the switch model. For the later, the order of the model is increased until a specified accuracy is achieved.

Originality/value
The use of ECE as boundary conditions for the RF simulation of MEMS switches has the advantage that the definition of ports is unambiguous and robust as the ports are clearly defined. The extraction approach has the advantage that the simplified model keeps the basic phenomena, i.e. the propagation of the signal along the lines. As the macromodel is realized with a netlist that uses transmission lines models, the lines’ extension is natural. The frequency dependence can be included in the model, if needed.
Stable compact modeling of piezoelectric energy harvester devices
Authors: Yuan Chengdong , Hu Siyang , Bechtold Tamara 
Published: April 2020

Purpose
Based on the framework of Krylov subspace-based model order reduction (MOR), compact models of the piezoelectric energy harvester devices can be generated. However, the stability of reduced piezoelectric model often cannot be preserved. In previous research studies, “MOR after Schur,” “Schur after MOR” and “multiphysics structure preserving MOR” methods have proven successful in obtaining stable reduced piezoelectric energy harvester models. Though the stability preservation of “MOR after Schur” and “Schur after MOR” methods has already been mathematically proven, the “multiphysics structure preserving MOR” method was not. This paper aims to provide the missing mathematical proof of “multiphysics structure preserving MOR.”

Design/methodology/approach
Piezoelectric energy harvesters can be represented by system of differential-algebraic equations obtained by the finite element method. According to the block structure of its system matrices, “MOR after Schur” and “Schur after MOR” both perform Schur complement transformations either before or after the MOR process. For the “multiphysics structure preserving MOR” method, the original block structure of the system matrices is preserved during MOR.

Findings
This contribution shows that, in comparison to “MOR after Schur” and “Schur after MOR” methods, “multiphysics structure preserving MOR” method performs the Schur complement transformation implicitly, and therefore, stabilizes the reduced piezoelectric model.

Originality/value
The stability preservation of the reduced piezoelectric energy harvester model obtained through “multiphysics structure preserving MOR” method is proven mathematically and further validated by numerical experiments on two different piezoelectric energy harvester devices.

Authors: Sundaramoorthy Prabhu , M. Balaji , K. Suresh , Natesan Ezhilventhan , K. Mohan 
Published: April 2020

Purpose
The main purpose of this research is to investigate finite-element analysis (FEA) on flux reversal-free stator switched reluctance motor (FRFSSRM) for industrial applications. The vibration analysis for an electrical machine is essential because of the acoustic noises. The acoustic noises originate by coincidence of natural frequencies of motor with the vibration frequencies.

Design/methodology/approach
The identification with the performance for FRFSRM by torque ripple, vibration. The vibration of the machine is because of unbalanced electromagnetic forces. The mutual coupled winding and a common pole between two adjacent exciting poles reduce these unbalanced forces.

Findings
The accelerometer is used to monitor the vibration amplitude in transient mode. A comparison study shows that the vibration is less in the E-core SRM than in the conventional flux reversal SRM.

Originality/value
The shorter flux path reduces the torque ripple and vibration content in SRM. This research article mainly focuses on the parameters such as vibration and torque ripple. The vibration of FRFSRM is identified by accelerometer; ANSYS Package predicts the simulation of the vibration measurement. The dynamic behaviors of this E-core SRM model with rated conditions the vibration had predicted.

Mediation effect was also found to be influential and statistically positive and significant by employee commitment between key HR practices (human capital, training, rewards) and SRP.Originality/valuecurrent study contributed to the body of knowledge in explaining relationship of human capital to employee commitment and SRP, further, inconclusive findings between training and rewards was also explained in the Takaful industry of the Southeast Asian region.
“It's a very different world”: work transition and employability of higher education graduates
Authors: Monteiro Sílvia , Almeida Leandro , García-Aracil Adela 
Published: April 2020

PurposeThis study addresses the specific topic of transition between higher education and the world of work, taking differences naturally inherent to the individual and to the surrounding micro and macro contexts. With a holistic approach, this paper aimed to provide a deeper understanding about the university-to-work transition process in a period of turbulence and continuous changes in the labour market.Design/methodology/approachThe three research questions that guide this qualitative study are as follows: (1) What are the factors that facilitate the transition to the labour market? (2) What are the factors that constrain the transition to the labour market? (3) What are graduates' perceptions of their employability? To answer these questions, eleven graduates were interviewed about facilitators and barriers of the transition process and perceptions of employability. Data collected from the interviews were then related to categories previously defined from the literature review. Version 12.0 of the NVivo software was used to support the process of data analysis.FindingsOverall, participants' discourse refer to a multidimensional and dynamic perspective of factors related with work transition and employability. The obtained results indicate that the lack of career agency during graduation and professional experiences, together with late career exploration processes, represent possible barriers of transition, especially in study fields with targeted job offers. Likewise, experiences promoting the development of competencies through supportive practice from teachers, mentors and colleagues are referred as facilitators of transition.Practical implicationsOne of the most consistent outcomes of the interviews conducted concerns the importance of a stronger focus on developing practical experiences during higher education studies. This empirical study demonstrated how this type of experience can mitigate the impact of the transition from university to the labour market.Originality/valueThis empirical study demonstrated how work being integrated into learning in curricula can mitigate the impact of the transition from university to the labour market. It offers important insights about possible strategies that could be adopted to promote graduates' employability from a perspective of shared responsibility.
