Disruptions in effort-based decision-making following acute optogenetic stimulation of ventral tegmental area dopamine cells
Authors: Fry Benjamin R. , Pence Nathan T. , McLocklin Andrew , Johnson Alexander W 
Published: December 2020

AbstractThe dopamine system has been implicated in decision-making particularly when associated with effortful behavior. We examined acute optogenetic stimulation of dopamine cells in the ventral tegmental area (VTA) as mice engaged in an effort-based decision-making task. Tyrosine hydroxylase-Cre mice were injected with Cre-dependent ChR2 or eYFP control in VTA. While eYFP control mice showed effortful discounting, stimulation of dopamine cells in ChR2 mice disrupted effort-based decision-making by reducing choice towards the lever associated with a preferred outcome and greater effort. Surprisingly, disruptions in effortful discounting were observed in subsequent test sessions conducted in the absence of optogenetic stimulation, however during these sessions ChR2 mice displayed enhanced high choice responding across trial blocks. These findings suggest increases in VTA dopamine cell activity can disrupt effort-based decision-making in distinct ways dependent on the timing of optogenetic stimulation.

Published: December 2020

AbstractThe apicomplexanPlasmodiumparasites replicate in the liver before causing malaria.P. vivaxcan also persist in the liver as dormant hypnozoites and cause relapses upon activation. The host water and solute channel aquaporin-3 (AQP3) has been shown to localize to the parasitophorous vacuole membrane (PVM) ofP. vivaxhypnozoites and liver schizonts, along with otherPlasmodiumspecies and stages. In this study, we use high-resolution microscopy to characterize temporal changes of the tubovesicular network (TVN), a PVM-derived network within the host cytosol, duringP. vivaxliver-stage infection. We demonstrate an unexpected role for the TVN in hypnozoites and reveal AQP3 associates with TVN-derived vesicles and extended membrane features. We further show AQP3 recruitment toToxoplasma gondii. Our results highlight dynamic host-parasite interactions that occur in both dormant and replicating liver-stageP. vivaxforms and implicate AQP3 function during this time. Together, these findings enhance our understanding of AQP3 in apicomplexan infection.
Financial development and economic growth in Tanzania: an ARDL and bound testing approach
Authors: Kapaya Saganga Mussa 
Published: December 2020

Purpose
The purpose of this study is to empirically weigh the evidence for financial depth, liquidity and efficiency role to economic growth, and test for the existence of cointegration between financial development variables and economic growth in Tanzania.

Design/methodology/approach
The study used the autoregressive distributed lag model with bound testing procedures. The sample covered yearly time-series data from 1980 to 2017, i.e. 38 years.

Findings
The results suggest that financial system depth is positively related to economic growth in the short run and that financial system liquidity and efficiency is strongly negatively associated with economic growth both in the short and long run. Further, it is found that financial development is cointegrated with economic growth. Thus, financial reforms and liberalisation have not fully brought the desired positive effects on economic growth yet.

Originality/value
The study uses principal component analysis to capture specific dimensions within the financial system as an intuitive way to aggregate financial development effects. Unlike studies that included several countries with heterogeneous characteristics, which are sometimes difficulty to homogenise, in recognition of countries’ unique experiences, this study uses data from Tanzania as a specific case. It documents pertinent pieces of evidence for a developing economy necessary for financial policy adjustments post the financial and economic liberalisation and reforms period. It nevertheless sheds light on financial policies for other comparable developing economies during and after both financial and economic liberalisation settings.
Can forensic accounting impact sustainable corporate governance?
Authors: Rehman Ali , Hashim Fathyah 
Published: December 2020

Purpose
The purpose of this paper is the measurement of forensic accounting’s (FA) impact on sustainable corporate governance (SCG) within Omani public listed companies. Beyond merely cataloging the latest criminal innovations and SCG problems, this paper offers a path forward to overcome the myriad threats that can harm the organization and society. FA and SCG can achieve, anticipate and prevent tomorrow’s fraud today before organizations reach the point of no return.

Design/methodology/approach
For this study, FA is an independent variable and SCG is the dependent variable. This study used a descriptive cross-sectional survey design. Data are collected by internet-based tool and analyzed via partial least squares structural equation modeling and Statistical Package for Social Sciences.

Findings
Result suggests that FA has a significant direct impact over SCG; moreover, FA can become the part of governance management toward the elimination of fraud and achievement of SCG.

Practical implications
This study can assist regulators, professional bodies and organizations in amending their codes of corporate governance and organizational policies by introducing the SCG clauses and making FA as a compulsory part of governance system.

Originality/value
Up to the best of the knowledge of researchers, there is no study conducted before which verifies the FA impact on SCG; moreover, previous relevant studies verify only one constituent for SCG, whereas this study is identifying three constituents necessary for SCG.
Intermediaries and social entrepreneurship identity: implications for business model innovation
Authors: Guerrero Maribel , Santamaría-Velasco Carlos A. , Mahto Raj 
Published: December 2020

PurposeThe authors propose a theoretical basis for understanding the role of ecosystem intermediaries in the configuration of social entrepreneurship identities in social purpose organisations (SPOs) and their business model innovations (BMIs).Design/methodology/approachAdopting a retrospective multiple-case study, the authors offer insights into the paths/elements that determine the building of 44 social entrepreneurship identities in the context of an emerging economy (Mexico).FindingsThe study sheds light on the role of intermediaries in the configuration of the entrepreneurial identities of Mexican SPOs and BMIs, as well as several externalities generated during the process of capturing the social and economic value, especially when social innovations are focussed on solving societal, economic and ecological social problems.Research limitations/implicationsThe first limitation is related to the analysis of intermediaries within the social entrepreneurship ecosystem, which needs more conceptual and empirical evidence. The second limitation is that the analysis focussed only on intervened SPOs, as the authors did not control for non-intervened SPOs. Thus, this allows for future in-depth analysis of intermediary efficiency in a focus group (intervened SPOs) and a control group (non-intervened SPOs).Practical implicationsThe study also provides insights for Mexican SPOs on how a social entrepreneurship identity helps to capture the value creation of social innovations within an innovation ecosystem. Indeed, it is strongly aligned with the United Nations' Social Development Goals.Originality/valueThe study enhances the discussion about how intermediaries could encourage social entrepreneurial identity, as well as how intermediary intervention could facilitate the design and implementation of BMIs in the innovation ecosystem.
Revisiting equity in healthcare spending through capability-approach: assessing the effectiveness of health-insurance schemes in reducing OOPE and CHE in India
Authors: Dwivedi Rinshu , Pradhan Jalandhar 
Published: December 2020

Purpose
This paper aims to draw theoretical insight from Sen’s capability-approach and attempts to examine the effectiveness of health-insurance-schemes in reducing out-of-pocket-expenditure (OOPE) and catastrophic-health-expenditure (CHE) in India.

Design/methodology/approach
Data were extracted from the National-Sample-Survey-Organization, 71st round on Health-2014. Generalized-linear-regression-model was used to investigate the impact of social-protection-schemes on OOPE and CHE.

Findings
A notable segment of the Indian population is still not covered under any health-insurance-schemes. The majority of the insured population was covered by publicly-financed-health-insurance-schemes (PFHIs), with a trivial-share of private-insurance. Households from 16–59 age-group, urban, literate, richest, southern-regions, using private-facilities and having ear and skin ailments have reported higher insurance coverage. Reimbursement was higher among elderly, literates, middle-class, central-regions, using private-facilities/insurance and for infections. Access to PFHIs significantly reduces the risk of OOPE and CHE. Unavailability of reimbursement exposes the population to a higher risk of CHE.

Research limitations/implications
Being a study based on secondary data sources, its applicability may vary as per the other social indicators.

Practical implications
Extending insurance-coverage alone cannot answer the widespread inequalities in health care. Rather, an efficiently managed reimbursement-mechanism could condense OOPE and CHE by enhancing the capability of the population to confront the undue financial burden.

Social implications
Extending the health-insurance-coverage to the entire population requires a better understanding of the underlying-dynamics and health-care needs and must make health-care affordable by enhancing the overall capability.

Originality/value
This research brings a theoretical and conceptual analysis for improving the health-insurance coverage among the community as a public health strategy.

Authors: Haider Khawaja Shafiq , Bintul Huda Aamina , Rasool Akhtar , Bukhari Syed Hashim Raza 
Published: December 2020

PurposeThe purpose of this paper is to identify the fault modes of a nonlinear twin-rotor system (TRS) using the subspace technique to facilitate fault identification, diagnosis and control applications.Design/methodology/approachFor identification of fault modes, three types of system malfunctions are introduced. First malfunction resembles actuator, second internal system dynamics and third represents sensor malfunction or offset. For each fault scenario, the resulting TRS model is applied with persistently exciting inputs and corresponding outputs are recorded. The collected input–output data are invoked in NS4SID subspace system identification algorithm to obtain the unknown fault model. The identified actuator fault modes of the TRS can be used for fault diagnostics, fault isolation or fault correction applications.FindingsThe identified models obtained through system identification are validated for correctness by comparing the response of the actual model under the fault condition and identified model. The results certify that the identified fault modes correctly resemble the respective fault conditions in the actual system.Originality/valueThe utilization of proposed work for current research emphasized the area of fault detection, diagnosis and correction applications that makes its value significantly. These modes when used for diagnosis purposes allow users to timely get intimated and rectify the performance degradation of the plant before it gets totally malfunctioned. Moreover, the slight performance degradation is also indicated when fault diagnosis is performed.
Vehicle routing in cold food supply chain logistics: a literature review
Authors: Awad Mahmoud , Ndiaye Malick , Osman Ahmed 
Published: December 2020

PurposeCold supply chain (CSC) distribution systems are vital in preserving the integrity and freshness of transported temperature sensitive products. CSC is also known to be energy intensive with a significant emission footprint. As a result, CSC requires strict monitoring and control management system during storage and transportation to improve safety and reduce profit losses. In this research, a systematic review of recent literature related to the distribution of food CSC products is presented and possible areas to extend research in modeling and decision-making are identified.Design/methodology/approachThe paper analyzes the content of 65 recent articles related to CSC and perishable foods. Several relevant keywords were used in the initial search, which generated a list of 214 articles. The articles were screened based on content relevance in terms of food vehicle routing modeling and quality. Selected articles were categorized and analyzed based on cost elements, modeling framework and solution approach. Finally, recommendations for future research are suggested.FindingsThe review identified several research gaps in CSC logistics literature, where more focused research is warranted. First, the review suggests that dynamic vehicle modeling and routing while considering products quality and environmental impacts is still an open area for research. Second, there is no consensus among researchers in terms of quality degradation models used to assess the freshness of transported cold food. As a result, an investigation of critical parameters and quality modeling is warranted. Third, and due to the problem complexity, there is a need for developing heuristics and metaheuristics to solve such models. Finally, there is a need for extending the single product single compartment CSC to multi-compartment multi-temperature routing modeling.Originality/valueThe article identified possible areas to extend research in CSC distribution modeling and decision-making. Modified models that reflect real applications will help practitioners, food authorities and researchers make timely and more accurate decisions that will reduce food waste and improve the freshness of transported food.

Authors: Setiawan Lukman 
Published: December 2020

Purpose
This paper aims to explore the relationship between knowledge sharing factors, emotional intelligence and team conflict on the team performance during the inter-institutionalized collaboration work process.

Design/methodology/approach
This study was conducted in South Sulawesi and Central Sulawesi Province’s hospitals. The study lasted for six months in 2017. The sampling was done by using cluster method and stratified random sampling, which was based on Hospital Type, level of Health Officers. These characteristics were considered to have represented quite heterogeneous information about the characteristics of health workers. Data analysis approach used in this study was partial least square (PLS) using WarpPLS software.

Findings
Based on the results of data analysis, it can be concluded that there is a significant direct influence between emotional intelligence to knowledge management, emotional intelligence to team conflict, and emotional intelligence to team performance.

Originality/value
Some previous research studies that have been done are by Hasanyl et al. (2015), Othman (2010), Sathitsemakul (2005), Nóra. Obermayer-Kovács (2014), Troth (2009), Leung (2010) and Luca and Tarricone (2001). The novelty of this research is on the effort to see the mediation of knowledge sharing, team conflict and structure mechanism to other variables developed in the research model.
Rotor-dynamic performance of porous hydrostatic thrust bearing operating under magnetic field
Authors: Kumar Vivek , Shah Vatsalkumar Ashokkumar , Singh Simran Jeet , Narwat Kuldeep , Sharma Satish C. 
Published: December 2020

Purpose
The porous bearings are commonly used in slider thrust bearings owing to their self-lubricating properties and cost effectiveness as compared to conventional hydrodynamic bearings. The purpose of this paper is to numerically investigate usefulness of porous layer in hydrostatic thrust bearing operating with magnetic fluid. The effect of magnetic field and permeability has been analysed on steady-state (film pressure, film reaction and lubricant flow rate) and rotor-dynamic (stiffness and damping) parameters of bearing.

Design/methodology/approach
Finite element approach is used to obtain numerical solution of flow governing equations (Magneto-hydrodynamics Reynolds equation, Darcy law and capillary equation) for computing abovementioned performance indices. Finite element method formulation converts elliptical Reynolds equation into set of algebraic equation that are solved using Gauss–Seidel method.

Findings
It has been reported that porosity has limited but adverse effects on performance parameters of bearing. The adverse effects of porosity can be minimized by using a circular pocket for achieving better steady-state response and an annular/elliptical pocket, for having better rotor-dynamic response. The use of magnetic fluid is found to be substantially enhancing the fluid film reaction (53%) and damping parameters (55%).

Practical implications
The present work recommends use of circular pocket for achieving better steady-state performance indices. However, annular and elliptical pockets should be preferred, when design criteria for the bearing are better rotor-dynamic performance.

Originality/value
This study deals with influence of magnetic fluid, porosity and pocket shape on rotor-dynamic performance of externally pressurized thrust bearing.

Load carrying capacity of a novel magnetic-liquid double suspension fixed pad thrust bearing
Authors: Wang Shengtong , Wu Ouyang , Li Zhe , Wang Bin 
Published: December 2020

Purpose
Proposing a new type of water-lubricated thrust bearing meets the load-bearing requirements of high-power shaft-less rim driven thrusters.

Design/methodology/approach
The designs were tested by establishing a bearing thermal-fluid-magnetic comprehensive simulation model and developing bearing fluid film force and magnetic simulation. Lubrication performance tests were carried out on the bearing test rig.

Findings
The Halbach array of magnet blocks is able to reach the maximum magnetic force. The material of sheath can help increase the magnetism. The magnetism is able to reduce wear during low-speed and the start-stop phase, while the eddy current loss at high speeds will lead to a decrease in magnetic force. The experiment found that the bearing was more stable at low speeds and would not demagnetize due to the temperature rise, but it is necessary to pay attention to the running stability at high speeds to prevent rubbing and impact.

Originality/value
An innovative combination of hydrodynamic pressure and permanent magnetic repulsion was observed to form a magnetic-liquid double suspension bearing with large bearing capacity.

Greenness and financial performance of European REITs
Authors: Morri Giacomo , Anconetani Rachele , Benfari Luca 
Published: December 2020

PurposeThe purpose of this paper is to investigate the link between greenness and the operating performance in 50 listed European real estate investment trusts (REITs).Design/methodology/approachUsing a sample of 50 listed European REITs, the analysis leverages on Ordinary least squares models to investigate the relationship between greenness and operating performance indicators. In particular, it examines three types of greenness indicators: the overall Green Real Estate Sustainability Benchmark (GRESB) rating, its two components (management and policy [MP] and implementation and measurement) and the seven aspect scores; return on equity (ROE) and return on assets (ROA) are the fundamental measures of REITs operating performance.FindingsThe results demonstrate a positive relationship between greenness indicators and operating performance in European REITs, but the impact on ROE and ROA differs depending on the GRESB variable analyzed. If the GRESB rating proved to be significant on ROE and ROA, none of its two components has an impact on ROA, and only the MP score has a positive relationship with ROE. Finally, of the seven aspect scores, only the stakeholder engagement is significant on the two dependent variables.Originality/valueThe commercial real estate sector has a significant role in tackling climate change issues. To incentivize the market to increase the investments in green buildings, it is essential to find a link between their sustainability characteristics and the improvements they deliver in terms of operating performance. Despite there being a substantial body of literature investigating this connection in the US REITs market, there is still limited knowledge on the relationship between green and operating indicators in the European REITs market.
