Published: August 2019

AbstractA qepA8+ Shigella flexneri was cultured from the stool of a traveler returning from India and East Asia. This chromosomally encoded qepA variant, has a six-base insertion, and may have been mobilized as part of a complex IS1-mediated composite transposon including catA1, aadA1, and blaOXA-1. In laboratory E. coli, qepA8 alone only conferred decreased ciprofloxacin susceptibility; however, it may work in combination with additional mechanisms to confer clinical resistance.

ABSTRACTThe cytoplasmic dynein motor complex transports essential signals and organelles from the cell periphery to perinuclear region, hence is critical for the survival and function of highly polarized cells such as neurons. Dynein Light Chain Roadblock-Type 1 (DYNLRB1) is thought to be an accessory subunit required for specific cargos, but here we show that it is essential for general dynein-mediated transport and sensory neuron survival. Homozygous Dynlrb1 null mice are not viable and die during early embryonic development. Furthermore, heterozygous or adult knockdown animals display reduced neuronal growth, and selective depletion of Dynlrb1 in proprioceptive neurons compromises their survival. Conditional depletion of Dynlrb1 in sensory neurons causes deficits in several signaling pathways, including β-catenin subcellular localization, and a severe impairment in the axonal transport of both lysosomes and retrograde signaling endosomes. Hence, DYNLRB1 is an essential component of the dynein complex.
Stumped! The limits of global governance in a commercialized world of cricket
Authors: Siddiqui Javed , Yasmin Sofia , Humphrey Christopher 
Published: August 2019

PurposeThe purpose of this paper is to analyse the shifting nature of governance reforms, both at global and national levels, in the increasingly commercialised game of cricket. The authors explore the inter-relationship and linkages between governance and commercialism, and in the process, question the contemporary reliance placed on governance as a generic counter-commercialist force and accountability aid.Design/methodology/approachThe analysis is based on a comprehensive analysis of cricketing archives, newspapers and online media. The authors specifically utilise a range of review reports, governance and accounting information from annual reports and websites of the International Cricket Council (ICC) as well as different national cricket governing bodies (NCBs).FindingsThe paper vividly demonstrates the importance of recognising the specific significance of different cultural traditions and modes of organising – and not presuming a particular form of impact. The findings highlight that the adoption of a dominant market logic by cricket administrators has resulted in a shift in the balance of power in favour of non-western nations. India has emerged as the clear leader and driving force shaping the way cricket is globally governed. The consequences have been profound but not in terms of delivering, enhanced standards of transparency and accountability. Drawing on institutional theory, the paper argues that the scale of the Board of Cricket Control of India’s financial and operational control over the ICC has not only led to an increasingly commercialised game but engendered divergent and highly questionable standards of governance at the level of NCBs.Originality/valueUnlike other global games, cricket has an imperialistic root, and has gone through the process of globalisation in relatively recent times. Also, the commercialisation of cricket has resulted in the global economic and power base shifting from the West to the East, giving us the opportunity to study the dynamics between commercialisation and governance in a quite different globalisation context that allows an assessment to be made of the culturally contingent nature of governance as a substantive organising force.

Published: August 2019

PurposeThe purpose of this paper is to examine the relationship between operational risk management and customer complaints. It also determines whether product complexity moderates the relationship between the operational risk management and customer complaints.Design/methodology/approachThis study utilizes a quantitative method: quantitative data were collected using a questionnaire. The population of this study is 1,845 local conventional bank branches based in Malaysia.FindingsThe findings revealed that components of operational risk management, namely practice of hazard identification and formulation of implementation of risk control, have negative and significant relationships with customer complaints. Empirical evidence confirmed the moderating effects of product complexity on the relationship between operational risk management and customer complaints.Originality/valueFrom the perspective of developing countries, the main contribution of this study is the elucidation of the effect of operational risk management on customer complaints in commercial banks in Malaysia. This study confirmed the usability of the resource-based view theory in the banking industry, as well as operational risk management as a bank resource.
An experience sampling approach to the workplace environment survey
Authors: Roskams Michael , Haynes Barry 
Published: August 2019

PurposeThe purpose of this study is to pilot test the effectiveness of the experience sampling approach for measuring employee satisfaction with the workplace environment. Additionally, the authors also aimed to explore, which aspects of environmental comfort have the strongest impact on momentary well-being and productivity.Design/methodology/approachIn total, 15 knowledge workers in an open-plan office environment were sent a brief survey (measuring environmental comfort, momentary well-being and perceived productivity) each day over an 11-day study period and provided 78 individual survey responses in total.FindingsAll but one of the measures on the survey had low test-retest reliability, indicating that employees’ experiences of environmental comfort varied significantly each time they completed the survey. Additionally, higher environmental comfort was associated with improved well-being and productivity.Practical implicationsThe results suggest that an experience sampling approach to the workplace occupant survey is justified to better capture the temporal variability in experiences of environmental comfort. The results also suggest that improving environmental comfort, particularly by reducing the level of distractions, will enable employees to work more productively.Originality/valueTo the best of the authors’ knowledge, this is the first field study which has attempted to directly address limitations in traditional occupant surveys by using an experience sampling approach rather than a one-time-only questionnaire.
MHD free convection flow in an inclined square cavity filled with both nanofluids and gyrotactic microorganisms
Authors: Sheremet Mikhail , Grosan Teodor , Pop Ioan 
Published: August 2019

Purpose
This paper aims to study the magnetohydrodynamic (MHD)-free convection flow in an inclined square cavity filled with both nanofluids and gyrotactic microorganism.

Design/methodology/approach
The benefits of adding motile microorganisms to the suspension include enhanced mass transfer, microscale mixing and anticipated improved stability of the nanofluid. The model includes equations expressing conservation of total mass, momentum, thermal energy, nanoparticles, microorganisms and oxygen. Physical mechanisms responsible for the slip velocity between the nanoparticles and the base fluid, such as Brownian motion and thermophoresis, are accounted for in the model.

Findings
It has been found that the Hartmann number suppresses the heat and mass transfer, while the cavity and magnetic field inclination angles characterize a non-monotonic behavior of the all considered parameters. A rise of the Hartmann number leads to a reduction of the influence rate of the magnetic field inclination angle.

Originality/value
The present results are original and new for the study of MHD-free convection flow in an inclined square cavity filled with both nanofluids and gyrotactic microorganisms.
Investigation of non-equilibrium boundary conditions considering sliding friction for micro/nano flows
Authors: Assam Ashwani , Kalkote Nikhil , Dongari Nishanth , Eswaran Vinayak 
Published: August 2019

Purpose
Accurate prediction of temperature and heat is crucial for the design of various nano/micro devices in engineering. Recently, investigation has been carried out for calculating the heat flux of gas flow using the concept of sliding friction because of the slip velocity at the surface. The purpose of this study is to exetend the concept of sliding friction for various types of nano/micro flows.

Design/methodology/approach
A new type of Smoluchowski temperature jump considering the viscous heat generation (sliding friction) has recently been proposed (Le and Vu, 2016b) as an alternative jump condition for the prediction of the surface gas temperature at solid interfaces for high-speed non-equilibrium gas flows. This paper investigated the proposed jump condition for the nano/microflows which has not been done earlier using four cases: 90° bend microchannel pressure-driven flow, nanochannel backward facing step with a pressure-driven flow, nanoscale flat plate and NACA 0012 micro-airfoil. The results are compared with the available direct simulation Monte Carlo results. Also, this paper has demonstrated low-speed preconditioned density-based algorithm for the rarefied gas flows. The algorithm captured even very low Mach numbers of 2.12 × 10−5.

Findings
Based on this study, this paper concludes that the effect of inclusion of sliding friction in improving the thermodynamic prediction is case-dependent. It is shown that its performance depends not only on the slip velocity at the surface but also on the mean free path of the gas molecule and the shear stress at the surface. A pressure jump condition was used along with the new temperature jump condition and it has been found to often improve the prediction of surface flow properties significantly.

Originality/value
This paper extends the concept of using sliding friction at the wall for micro/nano flows. The pressure jump condition was used which has been generally ignored by researchers and has been found to often improve the prediction of surface flow properties. Different flow properties have been studied at the wall apart from only temperature and heat flux, which was not done earlier.

Energetic-exergetic analysis of an air handling unit to reduce energy consumption by a novel creative idea
Authors: Yari Meysam , Kalbasi Rasool , Talebizadehsardari Pouyan 
Published: August 2019

Purpose
This study aims to simulate the flow and heat transfer through an air handling unit to reduce its energy consumption by a novel creative idea of using an air-to-air heat exchanger.

Design/methodology/approach
To do this, both first and second laws of thermodynamics energy and exergy balance equations were solved numerically by an appropriate developed computer code.

Findings
Using the air-to-air heat exchanger in dry conditions decreases the cooling coil load by 0.9 per cent, whereas the reduction for humid conditions is 27 per cent. Similarly, using air-to-air heat exchanger leads to an increase in the first law of efficiency in dry and humid conditions by 0.9 per cent and 36.8 per cent, respectively.

Originality/value
The second law of efficiency increases by 1.55 per cent and 2.77 per cent in dry and humid conditions, respectively. In other words, the effect of using an air-to-air heat exchanger in humid conditions is more than that in dry conditions.
Strategic behavioral pricing of the private residential development market – a simplified experimental approach
Authors: Ho David Kim Hin , Hui Eddie C.M. , Ho Tai Wing , Rengarajan Satyanarain 
Published: August 2019

PurposeThis paper aims to examine the behavior of “rational” residential developers, under game theory, for their pricing strategy in a competitive environment.Design/methodology/approachResults show that residential developers cooperate implicitly for long-term benefit, leading to a slow-down in sales. Developers are motivated to deviate from cooperating at the beginning and at the end of successive periods in a sub-market. Relatively high profits, earnable in the first few periods, provide an allowance to undercut prices and improve sales. For the last few periods, the punishment for any deviation from cooperating is insignificant or zero. Note that the first-mover advantage in a new market is evident. On the effect of uncertainty on the developer’s residential prices, results show that as uncertainty increases, prices decrease while price variability increases.Research limitations/implicationsThis study highlights the merits of a uniquely simplified experimental research design for the strategic behavioral pricing of the private residential development market using a game theoretic approach.Practical implicationsThis study enhances the understanding of the residential development strategy of developers in the residential development market.Originality/valueThere is limited research on pricing strategy for the private residential development market in Asia.
Typology of practices for managing consumer returns in internet retailing
Authors: Hjort Klas , Hellström Daniel , Karlsson Stefan , Oghazi Pejvak 
Published: August 2019

Purpose
The purpose of this paper is to explore, describe and categorise practices of managing product returns empirically in internet retailing.

Design/methodology/approach
A multiple case study was conducted involving 12 e-commerce firms and 4 logistics service providers. An integrative data collection approach of semi-structured interviews, documentation and observations was used to gain comprehensive managerial and operational descriptions of returns management (RM) processes.

Findings
The findings show inconsistent RM processes, with a plethora of practices implemented and organised differently across firms. RM processes are ambiguous; their design is a result of incremental changes over time, lacking strategy and goals. There is a mismatch between how they are described and understood in the literature and how they are actually used. Practices in gatekeeping, avoidance and reverse logistics are defined and categorised. These serve as a typology of practices for managers to (re)consider, along with 15 propositions on how RM is practised.

Research limitations/implications
The range of RM practices and the processes reflect a lack of scholarly attention and strategic view. Research is needed to develop clear goals on how the RM process can be better aligned with business strategies.

Practical implications
The typology of practices is a benchmark for internet retailers in their design of efficient RM processes.

Originality/value
Systematic and empirical research on RM is scarce compared to forward management. The study bridges this gap as one of the first to describe RM practices in depth, define service as a key activity, and identify a mismatch between theory and practice.
Does rivalry matter? An analysis of sport consumer interest on social media
Authors: Watanabe Nicholas Masafumi , Pegoraro Ann , Yan Grace , Shapiro Stephen L. 
Published: August 2019

Purpose
Previous research on rivalry games in sport has predominantly focused on understanding the nature of these games and their effects on consumer behavior. As such, the purpose of this paper is to conduct an empirical examination to provide better theoretical and empirical understanding of how rivalries may impact the posting of content online.

Design/methodology/approach
This research utilizes Twitter data measuring the number of posts by individuals about college football teams to model how often fans create content during game days. The models in this study were estimated using fixed-effects panel regressions.

Findings
After controlling for a number of factors, including the type of rivalry game, results indicate fans post more during traditional rivalries. Furthermore, newer rivalry games had less impact on the amount of content posted about a team.

Practical implications
The findings from this research provide sport marketers with important information regarding fan use of digital platforms. Notably, the results suggest rivalries can help to boost the volume of content individuals post about a team, indicating these games provide teams with an opportunity to maximize their engagement with fans and focus on key marketing objectives.

Originality/value
To date, there has been little examination considering whether rivalries affect behaviors in the digital realm. Therefore, the current investigation is one of the first studies to examine how rivalries impact social media behavior.

Authors: Khan Gitosree , Sengupta Sabnam , Sarkar Anirban 
Published: August 2019

Purpose
Service composition phenomenon based on non-scenario aspects are become the latest issues in enterprise software applications of the multi-cloud environment due to the phenomenal increase in a number of Web services. The traditional service composition patterns are hard to support the dynamic, flexible and autonomous service composition in the inter-cloud platform. To address this problem, this paper aims to describe a dynamic service composition framework (SCF) that is enriched with various structural and functional aspects of composition patterns in a cloud computing environment. The proposed methodology helps to integrate various heterogeneous cloud services dynamically to acquire an optimal and novel enterprise solution for delivering the service to the end-users automatically.

Design/methodology/approach
SCF and different composition patterns have been used to compose the services present in the inter-cloud architecture of the multi-agent-based system. Further, the proposed dynamic service composition algorithm is illustrated using a hybrid approach, where service are chosen according to various needs of quality of service parameters. Besides, a priority-based service scheduling algorithm is proposed that facilitates the automation of delivering cloud service optimally.

Findings
The proposed framework is capable of composing the heterogeneous service and facilitate the structural and functional aspects of service composition process in enterprise cloud-based applications in terms of flexibility, scalability, integrity and dynamicity of the cloud bus. The advantage of the proposed algorithm is that it helps to minimize the execution cost, processing time and get better success rate in delivering the service as per customer’s need.

Originality/value
The novelty of the proposed architecture coordinates cloud participants, automate service discovery pattern, reconfigure scheduled services and focus on aggregating a composite services in inter-cloud environments. Besides, the proposed framework supported several non-functional characteristics such as robustness, flexibility, dynamicity, scalability and reliability of the system.
A method to assist in the proper management of rule bases in Web information systems
Authors: Boujelben Abir , Amous Ikram 
Published: August 2019

Purpose
One key issue of maintaining Web information systems is to guarantee the consistency of their knowledge base, in particular, the rules governing them. There are currently few methods that can ensure that rule bases management can scale to the amount of knowledge in these systems environment.

Design/methodology/approach
In this paper, the authors propose a method to detect correct dependencies between rules. This work represents a preliminary step for a proposal to eliminate rule base anomalies. The authors previously developed a method that aimed to ameliorate the extraction of rules dependency relationships using a new technique. In this paper, they extend the proposal with other techniques to increase the number of extracted rules dependency relationships. The authors also add some modules to filter and represent them.

Findings
The authors evaluated their own method against other semantic methods. The results show that this work succeeded in extracting better numbers of correct rules dependency relationships. They also noticed that the rule groups deduced from this method’s results are very close to those provided by the rule bases developers.

Originality/value
This work can be applied to knowledge bases that include a fact base and a rule base. In addition, it is independent of the field of application.
