Does foreign direct investment influence R&D activity in the host country? Evidence from Vietnam
Authors: Ha Van , Holmes Mark J. , Hassan Gazi 
Published: July 2021

PurposeThis study focuses on the linkages between foreign direct investment and the research and development (R&D) and innovation activity of domestic enterprises in Vietnam.Design/methodology/approachThe Heckman selection model approach is applied to a panel dataset of nearly 7,000 Vietnamese firms for the 2011–2015 study period to investigate the impact of foreign presence on the R&D of local firms through horizontal and vertical linkages. Probit model estimation is employed to examine how foreign investment influences the innovation activity of local companies.FindingsWhile there are a small number of firms carrying out R&D activities in Vietnam, foreign or joint domestic–foreign venture firms are less inclined than domestic firms to undertake R&D. Domestic factors that include capital, labor quality, location and export status of firm have a significant effect on the decision of domestic firms to participate in R&D activity. Only forward linkages and the gross firm output are found to have an impact on the R&D intensity of domestic enterprises, while other factors appear to have no significant influence on how much firms spend on R&D activities.Practical implicationsIn order to promote the R&D activity of domestic firms, policy should focus on (1) the backward linkages between local firms in downstream sectors with their foreign suppliers in upstream sectors, and (2) the internal factors such as labor, capital or location that affect the decisions made by domestic firms.Originality/valueGiven that foreign investment may affect R&D and innovation activity of local firms in host countries, the impact is relatively unexplored for many emerging economies and not so in the case of Vietnam. The availability of a unique survey on Vietnamese firm technology and competitiveness provides the opportunity to address this gap in the literature.

Published: July 2021

Purpose
The purpose of this paper is to achieve the optimal system design of a four-wheel mobile robot on transmission line maintenance, as the authors know transmission line mobile robot is a kind of special robot which runs on high-voltage cable to replace or assist manual power maintenance operation. In the process of live working, the manipulator, working end effector and the working environment are located in the narrow space and with heterogeneous shapes, the robot collision-free obstacle avoidance movement is the premise to complete the operation task. In the simultaneous operation, the mechanical properties between the manipulator effector and the operation object are the key to improve the operation reliability. These put forward higher requirements for the mechanical configuration and dynamic characteristics of the robot, and this is the purpose of the manuscript.

Design/methodology/approach
Based on the above, aiming at the task of tightening the tension clamp for the four-split transmission lines, the paper proposed a four-wheel mobile robot mechanism configuration and its terminal tool which can adapt to the walking and operation on multi-split transmission lines. In the study, the dynamic models of the rigid robot and flexible transmission line are established, respectively, and the dynamic model of rigid-flexible coupling system is established on this basis, the working space and dynamic characteristics of the robot have been simulated in ADAMS and MATLAB.

Findings
The research results show that the mechanical configuration of this robot can complete the tightening operation of the four-split tension clamp bolts and the motion of robot each joint meets the requirements of driving torque in the operation process, which avoids the operation failure of the robot system caused by the insufficient or excessive driving force of the robot joint torque.

Originality/value
Finally, the engineering practicability of the mechanical configuration and dynamic model proposed in the paper has been verified by the physical prototype. The originality value of the research is that it has double important theoretical significance and practical application value for the optimization of mechanical structure parameters and electrical control parameters of transmission line mobile robots.
Optimisation of geotechnical surveys using a BIM-based geostatistical analysis
Authors: Mahmoudi Elham , Stepien Marcel , König Markus 
Published: July 2021

PurposeA principle prerequisite for designing and constructing an underground structure is to estimate the subsurface's properties and obtain a realistic picture of stratigraphy. Obtaining direct measure of these values in any location of the built environment is not affordable. Therefore, any evaluation is afflicted with uncertainty, and we need to combine all available measurements, observations and previous knowledge to achieve an informed estimate and quantify the involved uncertainties. This study aims to enhance the geotechnical surveys based on a spatial estimation of subsoil to customised data structures and integrating the ground models into digital design environments.Design/methodology/approachThe present study's objective is to enhance the geotechnical surveys based on a spatial estimation of subsoil to customised data structures and integrating the ground models into digital design environments. A ground model consisting of voxels is developed via Revit-Dynamo to represent spatial uncertainties employing the kriging interpolation method. The local arrangement of new surveys are evaluated to be optimised.FindingsThe visualisation model's computational performance is modified by using an octree structure. The results show that it adapts the structure to be modelled more efficiently. The proposed concept can identify the geological models' risky locations for further geological investigations and reveal an optimised experimental design. The modifications criteria are defined in global and local considerations.Originality/valueIt provides a transparent and repeatable approach to construct a spatial ground model for subsequent experimental or numerical analysis. In the first attempt, the ground model was discretised by a grid of voxels. In general, the required computing time primarily depends on the size of the voxels. This issue is addressed by implementing octree voxels to reduce the computational efforts. This applies especially to the cases that a higher resolution is required. The investigations using a synthetic soil model showed that the developed methodology fulfilled the kriging method's requirements. The effects of variogram parameters, such as the range and the covariance function, were investigated based on some parameter studies. Moreover, a synthetic model is used to demonstrate the optimal experimental design concept. Through the implementation, alternative locations for new boreholes are generated, and their uncertainties are quantified. The impact of the new borehole on the uncertainty measures are quantified based on local and global approaches. For further research to identify the geological models' risky spots, the development of this approach with additional criteria regarding the search neighbourhood and consideration of barriers and trends in real cases (by employing different interpolation methodologies) should be considered.
A new fuzzy approach for managing data governance implementation relevant activities

Published: July 2021

PurposeThe purpose of this paper is to propose an approach for managing relevant factors and activities for implementing data governance in an organization. The process of assessing the establishment of data governance in an organization is intrinsically imprecise, due to the characteristics of new problem settings, particularly in relation to newly generated alternatives or vaguely defined qualitative assessment criteria.Design/methodology/approachTo reject the inherent subjectiveness and imprecision involved in the evaluation process, the authors use the concept of fuzzy logic in this approach for developing the assessment model and analyzing the model for allocating the management efforts in the most efficient way to improve the data governance deployment level.FindingsThis paper identifies relevant factors and activities for implementing data governance in an organization and evaluates the state of data governance based on causal relationships between influential factors. In this study, factors are prioritized for effective allocation of limited management efforts in any improvement plan.Research limitations/implicationsThe interrelationships among factors are contextual and based on the perceptions of experts who may be biased as per their background and area of expertise. Meanwhile, lack of a data governance plan may cause failure during its implementation in an organization, as the worth of an organization's data will not be determined precisely. The paper has tremendous practical implications for organizations that intend to implement the data governance program and evaluate its state to design an improvement plan.Originality/valueThe paper proposes an approach for implementing data governance in an organization faced with limited resources for improvement.

Published: July 2021

AbstractIntroductionNo previous studies have examined the cross‐sectional association between fear of missing out (FOMO) and binge‐drinking among adolescents. The aim of the present study was: (i) to estimate the magnitude of this association; (ii) to assess the impact of potential confounders (i.e. sensation‐seeking, symptoms of depression and self‐regulation); and (iii) determine if it is uniform across all levels of these characteristics.MethodsCross‐sectional study of adolescents from 33 middle schools in Norway, stratified according to geographic location, urban and rural locations, and standard of living. Participants were a nation‐wide sample of N = 2646 adolescents (mean age 16.2 years, 43% boys). Self‐report data were collected on binge‐drinking, FOMO, sensation‐seeking, symptoms of depression and self‐regulation.ResultsOverall, 21% reported binge‐drinking ≤ once per month in the past 12 months, while 9% reported binge‐drinking more than once per month. Multinomial logistic regression showed that the crude effect, where greater FOMO was associated with greater risk of binge‐drinking, was substantial (relative‐risk ratio = 1.50 [1.35, 1.66], P < 0.001), but somewhat attenuated after including all potential confounders (relative‐risk ratio = 1.28 [1.14, 1.43], P < 0.001). Effect modification analyses showed that the effect of FOMO on binge‐drinking ≤ once per month was stronger for adolescents with low symptom levels of depression and weaker for adolescents at high levels of depression.Discussion and ConclusionNorwegian adolescents with higher FOMO have greater risk of binge‐drinking.

AbstractIntroductionThis study sought to determine: (i) whether decriminalisation of cannabis use would increase the proportion who would try the drug; and (ii) the proportion who would use more cannabis; and (iii) explore their characteristics.MethodsAustralian National Drug Strategy Household surveys were used to address (i)‐(iii). Significant independent predictors of (i) and (ii) were identified using logistic regression.ResultsAn estimated 4.2% of the population aged 14 and over (n = 882 708) who have never tried cannabis before would try it, if use of the drug were made legal, while 2.6% of the population aged 14 and over (537 000) would use more cannabis if its use were made legal. Respondents were more likely to say they would try cannabis if they were male, younger or suffered from a mild, moderate and/or severe level of psychological stress. Respondents were more likely to say they would use more cannabis if they were male, younger, psychologically stressed and not currently frequent users of the drug.Discussion and ConclusionsDecriminalisation of cannabis use is likely to result in an increase in consumption of the drug among young people with mental health problems. If cannabis use is decriminalised, Australian State and Territory Governments should make provision for a possible increase in demand for drug treatment and for public education on the risks associated with frequent/prolonged cannabis use.

Published: July 2021

AbstractOsteoarthritis and rheumatoid are most common form of arthritis disorder, affecting millions of people worldwide. This article presents a computer aided detection system (CAD) for early knee osteoarthritis and rheumatoid detection using X‐ray images and machine learning classifiers. This work also proposed a novel feature extractor from X‐ray images of knee to assist in detection and classification, called explainable Renyi entropic segmentation with Internet of Things (IoT) framework. The proposed method later utilizes model agnostic algorithm using post hoc explainability for extracting relevant information from prediction of knee joint segmentation. CAD system is integrated with an IoT framework and can be used remotely to assist medical practitioners in treatments of knee arthritis. The presented results show commendable improvement over different existing feature extractors in combination with different classifiers. The best result of proposed extractor method was obtained when combined with random forest classifier having Euclidean hyperparameter that gave an accuracy of 95.23%, among all the evaluators. The obtained results show the effectiveness of proposed feature extractor model to determine relevant features from knee and describe the suitable knee disorders.

Published: July 2021

AbstractRecently, the culture of American eels (Anguilla rostrate) in China has been impacted by emergence of a disease with signs of haemorrhagic gill necrosis. The gills of diseased eels are covered with petecchia and they bleed when the operculum is pressed. In this study, a novel American eel adomavirus (AEAdoV) was isolated from the diseased eels using the eel ovary cell line (EO). The virus proliferated in the EO cells with a maximum TCID50/ml of 106.29 ± 0.23 at 6 days post‐infection. The virions were non‐enveloped with a diameter of 75–85 nm and shown to be a DNA virus upon 5‐iodo‐2’‐deoxyuridine (IDU) treatment. PCR assays showed that AEAdoV encodes a superfamily 3 helicases (S3H) replicase and shared high similarities with Anguilla marmorata adomavirus (MEAdoV). Although no clinical signs or mortality was observed among the eels injected with AEAdoV, the virus was reisolated from livers, kidneys and gills of injected eels at 35 days post‐injection. Our results suggested that AEAdoV exhibited a latent infection in A. rostrata. The pathogenicity of the AEAdoV needs to be confirmed further.
Zooming In and Out of Virtual Jewish Prayer Services During the COVID‐19 Pandemic
Authors: Ben‐Lulu Elazar 
Published: July 2021

AbstractThis netnographic study examines Reform Jewish rituals transmitted by virtual platforms, Facebook and Zoom, during the COVID‐19 pandemic. Reform Judaism, which supports modern liberal theology, has adopted the usage of technology for Shabbat services. The transition from the physical space to the virtual one challenges the performance of the ritual: Rabbis change the ritual's structure, and during online services, the congregants have different feelings toward the congregation and their own spiritual worship, made manifest in changes in their usual religious gestures. A positive result of the move to the virtual space is that though the Reform Jewish congregations, as non‐Orthodox communities, have been excluded by the state, virtual prayers further expose Reform services to Israeli society. However, this might hinder societal support if it is shown that the community can conduct its services without an actual formal space. This study illuminates the intersection of virtual space, religious praxis, and political conflicts.

AbstractObjectiveTo assess the clinical utility of neostigmine methylsulfate administration in the diagnosis of suspected acquired myasthenia gravis (MG) in dogs and cats.DesignRetrospective study (2017‐2019).SettingFive university teaching hospitals and 2 private referral hospitals.AnimalsTwenty‐two dogs and 3 cats. Criteria for inclusion were clinical signs consistent with acquired MG, performance of a neostigmine challenge and acetylcholine receptor antibody titers.InterventionsNone.Measurements & main resultsThe route of neostigmine administration was recorded. Response to neostigmine challenge was determined via sequential evaluation of muscle strength and ambulation following administration of neostigmine methylsulfate. Response to neostigmine challenge was compared to acetylcholine receptor antibody titers, which were used as the biochemical gold standard in this study. Sixteen out of 22 dogs were diagnosed with acquired MG. Thirteen of 16 had a strong positive response to neostigmine challenge whereas 3 of 16 had no response. Two out of 3 dogs with polymyositis also had a strong positive response to neostigmine challenge. Weak positive results were seen with intracranial neoplasia (n = 1) and a dog with dilated cardiomyopathy and coxofemoral joint disease (n = 1). One cat was diagnosed with acquired MG and had a positive response to neostigmine challenge. Two cats had no response to neostigmine challenge and were diagnosed with alternate conditions. Two cats were premedicated with glycopyrrolate, one of which had a mild adverse response to neostigmine challenge (sialorrhea and mild transient tremors). Three out of 22 dogs had minimal adverse effects (sialorrhea and 1 dog with muscle tremors).ConclusionsThe neostigmine challenge appears to be safe and viable alternative to the previously utilized edrophonium challenge, particularly when weak positive responses are considered negative for acquired MG. Polymyositis cases may have a false positive response to neostigmine challenge.

Abstract
Due to the increasing bypass ratios of modern engines, the fan stage is increasingly becoming the dominant source of engine noise. Accordingly, it is becoming more and more important to develop not only efficient but also quiet fan stages. In this paper the noise emission of a fan for an aero-engine with bypass ratio of 19 is reduced within a multidisciplinary design optimization (MDO) by means of a hybrid noise prediction method while at the same time optimizing the aerodynamic efficiency. The aerodynamic performance of each configuration in the optimization is evaluated by stationary Reynolds-Averaged Navier- Stokes (RANS) simulations. These stationary flow simulations are also used to extract the aerodynamic excitation sources for the analytical fan noise prediction. The resulting large database of the optimization provides new insights into which extent an MDO can contribute to the design of both quiet and efficient fan stages. In addition to that the hybrid approach of numerical flow solutions and analytical description of the noise sources enables to understand the noise reduction mechanisms. In particular, the influence of rotor blade loading on the aerodynamic efficiency and the noise sources as well as the potential of configurations with a comparatively low number of outlet guide vanes (OGV) is explored.

The purpose of this study was to examine the effect of heat acclimation (HA) on thirst levels, sweat rate, and percentage of body mass loss (%BML), and changes in fluid intake factors throughout HA induction. Twenty-eight male endurance athletes (mean ± SD; age, 35 ± 12 years; body mass, 73.0 ± 8.9 kg; maximal oxygen consumption, 57.4 ± 6.8 ml·kg−1·min−1) completed 60 min of exercise in a euhydrated state at 58.9 ± 2.3% velocity of maximal oxygen consumption in the heat (ambient temperature, 35.0 ± 1.3 °C; relative humidity, 48.0 ± 1.3%) prior to and following HA where thirst levels, sweat rate, and %BML were measured. Then, participants performed 5 days of HA while held at hyperthermia (38.50–39.75 °C) for 60 min with fluid provided ad libitum. Sweat volume, %BML, thirst levels, and fluid intake were measured for each session. Thirst levels were significantly lower following HA (pre, 4 ± 1; post, 3 ± 1, p < .001). Sweat rate (pre, 1.76 ± 0.42 L/hr; post, 2.00 ± 0.60 L/hr, p = .039) and %BML (pre, 2.66 ± 0.53%; post, 2.98 ± 0.83%, p = .049) were significantly greater following HA. During HA, thirst levels decreased (Day 1, 4 ± 1; Day 2, 3 ± 2; Day 3, 3 ± 2; Day 4, 3 ± 1; Day 5, 3 ± 1; p < .001). However, sweat volume (Day 1, 2.34 ± 0.67 L; Day 2, 2.49 ± 0.58 L; Day 3, 2.67 ± 0.63 L; Day 4, 2.74 ± 0.61 L; Day 5, 2.74 ± 0.91 L; p = .010) and fluid intake (Day 1, 1.20 ± 0.45 L; Day 2, 1.52 ± 0.58 L; Day 3, 1.69 ± 0.63 L; Day 4, 1.65 ± 0.58 L; Day 5, 1.74 ± 0.51 L; p < .001) increased. In conclusion, thirst levels were lower following HA even though sweat rate and %BML were higher. Thirst levels decreased while sweat volume and fluid intake increased during HA induction. Thus, HA should be one of the factors to consider when planning hydration strategies.
