Role of social networking services for scientists in promoting scientific output on example of Polish representatives of social communication and media sciences
Authors: Kowalska-Chrzanowska Małgorzata , Krysiński Przemysław 
Published: August 2020

PurposeThis paper aims to answer the question of how the Polish representatives of social communication and media sciences communicate the most recent scientific findings in the media space, i.e. what types of publications are shared, what activities do they exemplify (sharing information about their own publications, leading discussions, formulating opinions), what is the form of the scientific communication created by them (publication of reference lists' descriptions, full papers, preprints and post prints) and what is the audience reception (number of downloads, displays, comments).Design/methodology/approachThe authors present the results of analysis conducted on the presence of the most recent (2017–2019) publications by the Polish representatives of the widely understood social communication and media sciences in three selected social networking services for scientists: ResearchGate, Google Scholar and Academia.edu. The analyses covered 100 selected representatives of the scientific environment (selected in interval sampling), assigned, according to the OECD classification “Field of Science”, in the “Ludzie nauki” (Men of Science) database to the “media and communication” discipline.FindingsThe conducted analyses prove a low usage level of the potential of three analysed services for scientists by the Polish representatives of social communication and media sciences. Although 60% of them feature profiles in at least one of the services, the rest are not present there at all. From the total of 113 identified scientists' profiles, as little as 65 feature publications from 2017 to 2019. Small number of alternative metrics established in them, implies, in turn, that if these metrics were to play an important role in evaluation of the value and influence of scientific publications, then this evaluation for the researched Polish representatives of social communication and media sciences would be unfavourable.Originality/valueThe small presence of the Polish representatives of the communication and media sciences in three analysed services shows that these services may be – for the time being – only support the processes of managing own scientific output. Maybe this quite a pessimistic image of scientists' activities in the analysed services is conditioned by a simple lack of the need to be present in electronic channels of scientific communication or the lack of trust to the analysed services, which, in turn, should be linked to their shortcomings and flaws. However, unequivocal confirmation of these hypotheses might be brought by explorations covering a larger group of scientists, and complemented with survey studies. Thus, this research may constitute merely a starting point for further explorations, including elaboration of good practices with respect to usage of social media by scientists.
Thermo-hydraulic and entropy generation analysis for magnetohydrodynamic pressure driven flow of nanofluid through an asymmetric wavy channel
Authors: Mehta Sumit Kumar , Pati Sukumar 
Published: August 2020

Purpose
The purpose of this paper is to analyze the thermal, hydraulic and entropy generation characteristics for the magneto-hydrodynamic (MHD) pressure-driven flow of Al2O3-water nanofluid through an asymmetric wavy channel.

Design/methodology/approach
Galerkin finite element method is used to solve the governing transport equations numerically within the computational domain using the appropriate boundary conditions. The temperature and flow fields are computed by varying Reynolds number (Re), Hartmann number (Ha) and nano-particle volume fraction (ϕ) in the following range: 10 ≤ Re ≤ 500, 0 ≤ Ha ≤ 75 and 0 ≤ ϕ ≤ 5%.

Findings
The formation of the recirculation zones in the wavy passages, the size of it and the strength of the vortices formed can be modulated by the application of the magnetic field. The overall heat transfer rate increases with Ha for all ϕ both for a lower and higher regime of Re although the enhancement is more for lower values of Re and nanofluids as compared to base fluid and for intermediate values of Re, the effect of a magnetic field is almost insignificant. The magnetic performance factor (PFmagnetic) decreases with Ha although the rate of decrement varies with Re. The increase ϕ also enhances PFmagnetic especially at lower and higher values of Re. The addition of nano-particle enhances the entropy generation at lower values of the Re, while the opposite effect is seen for higher values of Re.

Practical implications
The present study has enormous practical relevance for the design of heat exchanger applied for solar collectors, process plants, textile and aerospace applications.

Originality/value
The combined effects on the heat transfer rate and the associated pressure drop penalty due to the applied magnetic field for the flow of nanofluid through an asymmetric wavy channel have not been reported to date. The effect of the magnetic field on the formation of recirculation zones and hot spot intensity in the asymmetric wavy channel has been examined in detail. The PFmagnetic is investigated first time for the MHD nanofluid flow through a wavy channel.
Openness, resource sharing and digitalization – an examination of the current trends in Finland
Authors: Saarti Jarmo , Tuominen Kimmo 
Published: August 2020

Purpose
Although resource sharing between scholars is evolving rapidly, This paper uses paper-based interlibrary lending (ILL) procedures in the service repertoire of academic libraries. However, the current business model of acquiring toll-access journals and e-books does not seem to fit very well with traditional ILL practices. In addition, the new models of peer-to-peer resource sharing between academics seem to be much more effective than ILL. Scholars arrange access to the needed publications by using legal (buying, exchanging) and illegal means (Sci-Hub, etc.). Furthermore, the demands for open access have increased, voiced not only by librarians and science funders but also by politicians. This development might change the scholarly publication ecosystem, even though older publications are still likely to remain closed.

Design/methodology/approach
This paper contrasts the ILL and usage statistics of Finnish university libraries with the use of ResearchGate, a popular academic social network, which we treat as an example of a peer-to-peer sharing service.

Findings
Based on the data, there seems to be a change of paradigm in the resource sharing: the traditional ILL seems to be decreasing and becoming more like a niche service and the digital use and use of social media peer-to-peer resource sharing applications seem to increase rapidly.

Originality/value
The paper examines current resource sharing trends. The analysis is based on the data of Finnish resource sharing, interlibrary lending and ResearchGate usage.
A survey on national culture and corporate financial decisions: current status and future research
Authors: Kutan Ali , Laique Usama , Qureshi Fiza , Rehman Ijaz Ur , Shahzad Faisal 
Published: August 2020

PurposeThe extant literature provides substantial evidence that various facets of national culture play a significant role in corporate financial decision making. We systematically review the role of national culture on the various thematic domains of corporate financial decision making to outline what have been studies thus far and what needs to be studied.Design/methodology/approachKeywords such as national culture, organizational culture, power distance, uncertainty avoidance, masculinity, risk aversion and individualism for a search in the prominent academic literature databases are used. The studies related to the corporate financial decision making that is tied with these keywords are identified and selected for the systematic review.FindingsThe review of extant literature suggests strong evidence that national culture has a significant role in influencing corporate cash holding, corporate risk-taking, individual behaviour of the financial managers and initial public offering by the corporations. The review also indicates, although extant studies have examined the role of national culture in the key corporate financial decisions, evidence on the role of national culture in the firm's investment efficiency aspects is rather scarce. Also, what explains the role of national culture in corporate financial decision making has not been empirically exploited through causal mechanisms.Practical implicationsThe findings of the studies help advance our understanding of the current research status concerning the role played by the national culture in shaping corporate financial decisions and raise important future calls.Originality/valueTo best of our knowledge, no prior study has systematically reviewed the role of national culture in the thematic domains of corporate financial decision making.
Factors affecting the compactness of filter cake for diaphragm wall slurry
Authors: Fengjun Zhang , Cui Kong , Qianbao Chen 
Published: August 2020

Purpose
The purpose of this paper is to explore the factors that affect the compactness of the mud filter cake, so as to prepare diaphragm wall slurry with good uniformity, small filtration loss and excellent recycling performance.

Design/methodology/approach
In this paper, the thickness, filtration loss and slurry viscosity of the filter cake are used as the characterization methods. The effects of pore depth, slurry specific gravity, intercalated metal ions, bridging polymer and water-soluble polymer on the compactness of the filter cake were studied.

Findings
The experimental results showed that the slurry's own pressure (pore depth) and specific gravity have little influence on the compactness of the filter cake and K+ can be considered as an auxiliary filtration loss reduction factor. Both the sulfonate copolymer and the potassium polyacrylate particle can significantly reduce the filtration loss of the slurry, which can effectively improve the filter cake compactness. Moreover, the composite application of potassium polyacrylate particles in the sizes of 80–100 and 150–200 meshes can exhibit a better filter cake compaction effect.

Originality/value
It solves the problems of high pulping cost, serious pollution of the environment, poor quality of filter cake formation and large filtration loss during the construction of the diaphragm wall, which improved the construction quality of the diaphragm wall.
Fabrication of a piezoelectrically driven micropositioning 3-DOF stage with elastic body using a multi-material 3D printer
Authors: Baek Sang-Woo , Cho Nahm-Gyoo , Lee Dong-Hyeok 
Published: August 2020

Purpose
This paper aims to propose a method for manufacturing multi-material monolithic structures with flexible materials to construct the elastic body by using a dual-nozzle three-dimensional printer to develop a piezoelectric (PZT)-driven micropositioning stage with three degrees of freedom (3-DOF) and flexure hinges.

Design/methodology/approach
Polylactic acid (PLA) and nylon were used for the lever structure’s frame and flexure hinge, respectively. Additionally, the stage consisted of three PZT actuators for fine movement in the nanometer scale in 3-DOF (x, y and θ-directions). For the design of the stage, the kinematic analysis model and the finite element method (FEM) analysis was undertaken for comparing between PLA with nylon (multi-material), PLA (single material) and aluminum (conventional-material). In addition, two verification experiments were implemented for the fabricated prototype stage. First, to evaluate various assessments (lever ratio, hysteresis, coupling error and resolution), a measurement is carried out using the three capacitive sensors. Then, a two-camera-vision measurement experiment was performed to verify the displacement and lever ratio over the full-scale working range of the fabricated positioning stage, and the results from the experimentation and the FEM analysis were compared.

Findings
The authors confirmed enhancements in the properties of the lever structure frame, which requires stiffness and of the hinge, which requires flexibility for elastic deformation. Comparing FEM analysis and experimental results, although the performance as shown by experimental results was lower: the maximum difference being 3.4% within the end-point working range; this difference was sufficient to be a plausible alternative for the aluminum-based stage.

Originality/value
Multi-material monolithic-structure fabrication has an effective advantage in improving the performance of the stage, by using a combination of materials capable of reinforcing the desired characteristics in the necessary parts. It was verified that the fabricated stage can substitute the aluminum-based stage and can achieve a higher performance than single-material stages. Thus, precise-positioning stages can be manufactured in many kinds of structures with various properties and contribute to weight reduction and low costs for application equipment.
Embedding SMEs in national systems of innovation: Participant perceptions of Australia's CRC‐P program
Authors: Noble David , Charles Michael B. , Keast Robyn , Carlopio James 
Published: August 2020

AbstractGovernments throughout the world employ a variety of policy mechanisms to promote economy‐enhancing innovation, although the embedding of SMEs in national systems of innovation has generally proved problematic. The Australian Cooperative Research Centres – Projects Program represents a recent attempt to do precisely this. Interviews with participants in the first two rounds of the Program report high levels of satisfaction, but also highlight potential for friction between SMEs and research providers, together with the opportunity for strategic manipulation. This study provides government officials and other stakeholders with preliminary recommendations regarding where the Program is succeeding, and where further vigilance may be required.
Planning the supply of aged care services: It's time to talk denominators
Authors: Gibson Diane 
Published: August 2020

AbstractObjectivesThis paper explores how changes in demography, service use and the aged care system have implications for the appropriateness of the denominator in the aged care provision ratio.MethodsOfficial statistics were analysed to create five alternative scenarios for residential care planning in a 2000‐2027 time series.ResultsThe four age‐based denominators and a revised denominator incorporating age‐ and sex‐specific disability rates generated diverse levels of absolute supply. The 75+ denominator produced 1400 fewer beds than the 70+ denominator by 2018, but over 14 000 additional beds by 2027.ConclusionThe 70+ based ratio developed almost forty years ago has served its purpose reasonably well. However, changes in the nature of the aged care system, different patterns of use by age and sex, and demographic changes suggest that long‐term aged care planning requires careful review in choosing a more robust version of the provision ratio for the future.

Published: August 2020

AbstractBackgroundAllergic asthma is characterized by type 2 inflammation. We have shown the presence of increased type 2 inflammation in patients with severe asthma and those with frequent exacerbations. However, it is not known whether increased type 2 inflammation drives asthma exacerbations. This study aims to determine Th2 immune parameters in patients presenting to the emergency department (ED) with an acute asthma exacerbation and correlate these parameters with clinical and physiological measures of asthma.MethodsSixteen adults presenting to the ED with acute asthma exacerbations were recruited after giving informed consent. Ten patients returned 2 weeks later for follow‐up. Physiological parameters, asthma control (ACQ6), asthma quality of life (AQLQ) questionnaires, and venous blood were collected during both visits. An immune cell profiling was performed by whole blood flow cytometry: CD4+ T cells, Th2 cells (CD4+CRTh2+ T cells and % of CD4+ T cells expressing CRTh2), eosinophils and innate lymphoid cells (ILC2).ResultsDuring exacerbation, peripheral blood Th2 cell numbers correlated with ACQ6 and AQLQ scores, while ILC2 and eosinophil numbers did not. Subjects had higher % of CD4+ T cells expressing CRTh2 and worse FEV1 during exacerbation compared with the follow‐up. The decrease in the % of CD4+ T cells expressing CRTh2 seen during the follow‐up visit correlated with the improvement in lung function.ConclusionsThese data suggest that Th2 cells in peripheral blood may be a sensitive measure of increasing symptoms in patients with asthma exacerbations and may serve as a biomarker of an asthma exacerbation.

AbstractPurposeTo determine microvascular changes in children with a history of retinopathy of prematurity (ROP) and in a control group of full‐term children.MethodsIn a cross‐sectional study, 30 eyes of 15 children aged 6–8 years with a history of ROP were evaluated with swept‐source optical coherence tomography angiography (SS‐OCTA). Twenty‐eight eyes of 22 age‐matched full‐term children served as a healthy control group. The foveal avascular zone (FAZ), vessel density (VD) and choroidal vascular flow area (VFA) were evaluated on OCTA and correlated with central retinal thickness (CRT), visual acuity (VA), birth weight (BW), gestational age (GA) and ROP stages.ResultsTwenty‐two eyes of 14 children with a history of ROP (stage 1–3) and 25 eyes of 19 full‐term children were available for evaluation. In the ROP group, the gestational age was 27 ± 2 weeks and birth weight was 781 ± 164 g. In the ROP group, CRT was higher in the central ETDRS segment (mean difference [95% CI]: 32.8 µm [18.7; 47.0], p = 0.0002) compared to the controls. Smaller mean FAZ area (−0.12 [−0.19; −0.04], p = 0.004) and perimeter (−662 [−1228; −96], p = 0.03) was found in comparison to the control group. An oval shape of the FAZ was observed among patients with a history of ROP. The mean central VD of the superficial plexus was 28 ± 8/23 ± 8% and of the deep plexus 7 ± 7/3 ± 5% (ROP group/control group; p > 0.05). No statistically significant difference was found regarding the choroidal VFA. Only weak correlation of FAZ and VD with function was observed.ConclusionsSwept‐source optical coherence tomography angiography imaging revealed significant microvascular anomalies in children with a history of ROP indicating disturbance of early morphological development of the central retina.

Published: August 2020

AbstractGlaucoma is a widespread sight‐threatening condition often only recognized when very pronounced. It is initially characterized by peripheral visual field losses, while advanced stages also affect the central vision. Some of these patients may experience visual hallucinations, the Charles Bonnet syndrome (CBS). In this systematic review and meta‐analysis, we provide an overview of the literature dealing with the prevalence of CBS in patients with glaucoma. We searched the databases PubMed/MEDLINE, Embase, Web of Science, the Cochrane Central and PsycInfo on 22 March 2020. Eight studies (n = 827 patients) were identified and included for a qualitative and quantitative analysis. No studies included a representative sample of patients with only glaucoma. In patients with glaucoma in different stages and with ocular comorbidities, prevalence of CBS was 2.8% (CI95%: 0.7–6.1%). Among patients with glaucoma where all had bilateral low visual acuity, prevalence of CBS was 13.5% (CI95%: 8.4–19.6%). In patients with glaucoma who visited vision rehabilitation clinics, presumably due to an extensive vision impairment, prevalence of CBS was 20.1% (CI95%: 16.8–23.6%). Risk factors of CBS besides low vision were high age, female gender, reduced contrast sensitivity and not living alone. Taken together, we find that CBS may not be rare in patients with advanced glaucoma with and without ocular comorbidities. However, limitations of the current literature should be highlighted and careful approach towards conclusions is important. More studies are needed to better understand the prevalence and risk factors among different populations of patients with glaucoma.
Cluster non‐Gaussian functional data

Published: August 2020

AbstractGaussian distributions have been commonly assumed when clustering functional data. When the normality condition fails, biased results will follow. Additional challenges occur as the number of the clusters is often unknown a priori. This paper focuses on clustering non‐Gaussian functional data without the prior information of the number of clusters. We introduce a semiparametric mixed normal transformation model to accommodate non‐Gaussian functional data, and propose a penalized approach to simultaneously estimate the parameters, transformation function, and the number of clusters. The estimators are shown to be consistent and asymptotically normal. The practical utility of the methods is confirmed via simulations as well as an application of the analysis of Alzheimer's disease study. The proposed method yields much less classification error than the existing methods. Data used in preparation of this paper were obtained from the Alzheimer's Disease Neuroimaging Initiative database.

SummarySurvival for patients diagnosed with mantle cell lymphoma (MCL) has improved drastically in recent years. However, patients carrying mutations in tumour protein p53 (TP53) do not benefit from modern chemotherapy‐based treatments and have poor prognosis. Thus, there is a clinical need to identify missense mutations through routine analysis to enable patient stratification. Sequencing is not widely implemented in clinical practice for MCL, and immunohistochemistry (IHC) is a feasible alternative to identify high‐risk patients. The aim of the present study was to investigate the accuracy of p53 as a tool to identify patients withTP53missense mutations and the prognostic impact of overexpression and mutations in a Swedish population‐based cohort. In total, 317 cases were investigated using IHC and 255 cases were sequenced, enabling analysis of p53 andTP53status among 137 cases divided over the two‐cohort investigated. The accuracy of predicting missense mutations from protein expression was 82%, with sensitivity at 82% and specificity at 100% in paired samples. We further show the impact of p53 expression andTP53mutations on survival (hazard ratio of 3·1 in univariate analysis for both), and the association to risk factors, such as high MCL International Prognostic Index, blastoid morphology and proliferation, in a population‐based setting.
