AbstractRationaleCoronavirus disease 2019 (COVID-19) can cause a viral pneumonia together with other extrapulmonary complications. Acute cardiac related injury (ACRI) is common in hospitalized COVID-19 patients.ObjectiveTo explain the pathological mechanism of ACRI and improve the treatment strategy by retrospectively observing the factors associated with ACRI and factors affecting the prognosis of ACRI with COVID-19 at an early stage.Methods619 COVID-19 patients were from Tongji Hospital, Wuhan. Student’s t test was used for continuous variables while Pearson χ2 test for categorical factors. Univariable and multivariable logistic regression models were applied to estimate odds ratio (OR) with 95% confidence interval (CI).ResultsAmong the 619 OOS Level-I hospitalized COVID-19 patients, 102 (16.5%) were defined as ACRI (stage-1: 59 cases, stage-2: 43 cases). 50% of ACRI patients developed into severe cases and 25 patients died(CFR=24.5%), 42 times that of non-ACRI patients. Elderly (OR=2.83, P<0.001), HTN (OR=2.09, P=0.005), γ-globulin (OR=2.08, P=0.004), TCM (OR=0.55, P=0.017), PLT (OR=2.94, P<0.001) and NLR (OR=2.20, P=0.004) were independently correlated with ACRI. SBP ⩾ 140, dyspnea, DM, smoking history were correlated with ACRI-stage2 only. In the prognostic subgroup analysis of ACRI patients, γ-globulin treatment could prolong LOS (29.0 ± 7.2 days Vs 23.5 ± 8.1 days, P=0.004). TCM (OR=0.26, P=0.006), SBP ⩾ 160 (OR= 22.70, P=0.005), male (OR=2.66, P=0.044) were associated with severe illness while corticosteroids treatment (OR=3.34, P=0.033) and male (OR=4.303, P=0.008) with death. Surprisingly, we found the mortality of non-elderly patients is higher than elderly (32.4% VS 20.0%, P=0.164), and both IKF and RASI treatment were not correlated with any prognostic indicators including severe, death and LOS.ConclusionThis study observed that several non-traditional issues were associated with early cardiac injury in COVID-19 while many traditional cardiovascular risk factors were not. Besides elderly and male, hypertension was confirmed to be the most important risk factor.

AbstractBackgroundCoronavirus disease 2019 (COVID-19) is a global pandemic caused by the severe acute respiratory syndrome coronavirus 2 (SARS-Cov-2). It has been found that coronary artery disease (CAD) is a comorbid condition for COVID-19. As the risk factors of CAD, whether blood lipids levels are causally related to increasing susceptibility and severity of COVID-19 is still unknown.DesignWe performed two-sample Mendelian Randomization (MR) analyses to explore whether dyslipidemia, low density lipoprotein cholesterol (LDL-c), high density lipoprotein cholesterol (HDL-c), triglyceride (TG) and total cholesterol (TC) were causally related to COVID-19 risk and severity. The GWAS summary data of blood lipids involving in 188,578 individuals and dyslipidemia in a total of 53,991 individuals were used as exposures, respectively. Two COVID-19 GWASs including 1,221 infected patients and 1,610 severe patients defined as respiratory failure were employed as outcomes. Based on the MR estimates, we further carried out gene-based and gene-set analysis to explain the potential mechanism for causal effect.ResultsThe MR results showed that dyslipidemia was casually associated with the susceptibility of COVID-19 and induced 27% higher odds for COVID-19 infection (MR-IVW OR = 1.27, 95% CI: 1.08 to 1.49, p-value = 3.18 × 10−3). Moreover, the increasing level of blood TC will raise 14 % higher odds for the susceptibility of COVID-19 (MR-IVW OR = 1.14, 95% CI: 1.04 to 1.25, p-value = 5.07 × 10−3). Gene-based analysis identified that ABO gene was associated with TC and the gene-set analysis found that immune processes were involved in the risk effect of TC.ConclusionsWe obtained three conclusions: 1) Dyslipidemia is casually associated with the susceptibility of COVID-19; 2) TC is a risk factor for the susceptibility of COVID-19; 3) The different susceptibility of COVID-19 in specific blood group may be partly explained by the TC concentration in diverse ABO blood groups.
Investigating academic library responses to predatory publishing in the United States, Canada and Spanish-speaking Latin America
Authors: Buitrago Ciro Jairo , Bowker Lynne 
Published: July 2020

PurposeThis is a comparative investigation of how university libraries in the United States, Canada and Spanish-speaking Latin America are responding to predatory publishing.Design/methodology/approachThe Times Higher Education World University Rankings was used to identify the top ten universities from each of the US and Canada, as well as the top 20 Spanish-language universities in Latin America. Each university library's website was scrutinized to discover whether the libraries employed scholarly communication librarians, whether they offered scholarly communication workshops, or whether they shared information about scholarly communication on their websites. This information was further examined to determine if it discussed predatory publishing specifically.FindingsMost libraries in the US/Canada sample employ scholarly communication librarians and nearly half offer workshops on predatory publishing. No library in the Latin America sample employed a scholarly communication specialist and just one offered a workshop addressing predatory publishing. The websites of the libraries in the US and Canada addressed predatory publishing both indirectly and directly, with US libraries favoring the former approach and Canadian libraries tending towards the latter. Predatory publishing was rarely addressed directly by the libraries in the Latin America sample; however, all discussed self-archiving and/or Open Access.Research limitations/implicationsBrazilian universities were excluded owing to the researchers' language limitations. Data were collected between September 15 and 30, 2019, so it represents a snapshot of information available at that time. The study was limited to an analysis of library websites using a fixed set of keywords, and it did not investigate whether other campus units were involved or whether other methods of informing researchers about predatory publishing were being used.Originality/valueThe study reveals some best practices leading to recommendations to help academic libraries combat predatory publishing and improve scholarly publishing literacy among researchers.
Simulation of induction thermography NDT technique using SIBC
Authors: Ba Abdoulaye , Bui Huu Kien , Berthiau Gérard , Trichet Didier , Wasselynck Guillaume 
Published: July 2020

Purpose
This paper aims to present a lightened 3D finite element model (FEM) for coupled electromagnetic thermal simulation of the induction thermography non-destructive testing (NDT) technique to reduce the computation time.

Design/methodology/approach
The time harmonic electromagnetic problem is expressed in A – ϕ formulation and lightened by using the surface impedance boundary condition (SIBC) applied to both the massive induction coil surface and the surface of conductor workpiece including open cracks. The external circuit is taken into account by using the impressed voltage or the impressed current formulation. The thermal diffusion in the workpiece is solved by using surface electromagnetic power density as thermal source.

Findings
The accuracy and the usefulness of the method for the design of the induction thermography NDT technique have been shown with acceptable deviation compared with a full FEM model. It is also observed that at high frequency, when the ratio between the local radius of the conductor and the skin depth is high, a very good accuracy can be obtained with the SIBC methods. At lower frequency, the effect of the curvature of the surface becomes significant. In this case, the use of the Mitzner’s impedance can help to correct the error.

Originality/value
The SIBC can be used for both massive coil and workpieces with open cracks to alleviate 3D FEMs of the coupled electrothermal model. The implementation in matrix form of the coupled electrothermal formulation is given in details. The comparisons with reference analytical solution and full 3D FEM show the accuracy and performance of the method. In the test case presented, the computation time is 6.6 times lower than the classical model.

Published: July 2020

PurposeThe purpose of this study is to explore communication of hazard-resistant construction techniques after disaster in the absence of outside influence. It further aims to unpack the barriers and drivers in the adoption of knowledge processes to identify strategic recommendations to enlarge adoption of safer construction practices by local construction actors.Design/methodology/approachThis paper is based on an analysis of stakeholders’ perspectives during post-disaster reconstruction in the Philippines in the province of Busuanga after Typhoon Haiyan in 2013. Data were collected from six communities that received no external housing assistance, analyzing surveys from 220 households, 13 carpenters, 20 key actors coordinating reconstruction or recovery efforts, as well as 12 focus group discussions.FindingsThis research argues for a stronger role of governmental agencies, vocational training schools and engineers. Current communication of typhoon-resistant construction knowledge is ineffective to stimulate awareness, understanding and adoption by local construction actors and self-recovering households.Research limitations/implicationsThe analysis in this study focuses on a small sample of communities in the west of the Philippines that are not frequently affected by typhoons.Originality/valueThis is one of the few scholarly works in the Philippines focused on adoption of safer construction practices by community-based construction actors when technical housing assistance is absent.
When the mountain broke: disaster governance in Sierra Leone
Authors: Melis Samantha , Hilhorst Dorothea 
Published: July 2020

PurposeWhen a major landslide and floods devastated Freetown, Sierra Leone had just overcome the Ebola crisis, which had left its mark on socio-political relations between different disaster response actors. With international disaster response frameworks increasingly shifting to local ownership, the national government was expected to assume a coordinating role. However, in “post-conflict” settings such as Sierra Leone, intra-state and state–society relations are continuously being renegotiated. This study aimed to uncover the complexities of state-led disaster response in hybrid governance setting at national and community levels in the response to the 2017 landslide and floods.Design/methodology/approachDuring the four months of fieldwork in Freetown in 2017, semi-structured interviews and focus group discussions with various state, aid and societal actors were conducted.FindingsThe findings show that a response to policy building on the idea of a uniform state response did not take into account intra-state power politics or the complexity of Sierra Leone's hybrid governance.Practical implicationsThis paper argues for a more nuanced debate in humanitarian governance and practice on the localisation of aid in post-conflict and fragile settings.Originality/valueThe study's findings contribute to the literature on the disaster–conflict nexus, identifying paradoxes of localised disaster response in an environment with strong national–local tensions. The study highlights intra-local state dynamics that are usually overlooked but have a great impact on the legitimacy of different state authorities in disaster response.
Lumped parameter magnetic equivalent circuit model for design of segmented PM consequent pole flux switching machine
Authors: Ullah Wasiq , Khan Faisal , Umair Muhammad 
Published: July 2020

Purpose
The purpose of this paper is to investigate an alternative simplified analytical approach for the design of electric machines. Numerical-based finite element method (FEM) is a powerful tool for accurate modelling and electromagnetic performance analysis of electric machines. However, computational complexity, magnetic saturation, complex stator structure and time consumption compel researchers to adopt alternate analytical model for initial design of electric machine especially flux switching machines (FSMs).

Design/methodology/approach
In this paper, simplified lumped parameter magnetic equivalent circuit (LPMEC) model is presented for newly developed segmented PM consequent pole flux switching machine (SPMCPFSM). LPMEC model accounts influence of all machine parts for quarter of machine which helps to reduce computational complexity, computational time and drive storage without affecting overall accuracy. Furthermore, inductance calculation is performed in the rotor and stator frame of reference for accurate estimation of the self-inductance, mutual inductance and dq-axis inductance profile using park transformation.

Findings
The developed LPMEC model is validated with corresponding FEA using JMAG Commercial FEA Package v. 18.1 which shows good agreement with accuracy of ∼98.23%, and park transformation precisely estimates the inductance profile in rotor and stator frame of reference.

Practical implications
The model is developed for high-speed brushless AC applications.

Originality/value
The proposed SPMCPFSM enhance electromagnetic performance owing to partitioned PMs configuration which make it different than conventional designs. Moreover, the developed LPMEC model reduces computational time by solving quarter of machine.
Music education and cultural and national values
Authors: Ho Wai-Chung , Law Wing-Wah 
Published: July 2020

PurposeThe purpose of this paper is to examine music teachers' perceptions of teaching cultural and national values (also defined as national cultural values) to explore the tensions facing school music education in the choice of music types to be delivered in Hong Kong and Taiwan.Design/methodology/approachWith specific regard to music teachers' perceptions of “values,” “music cultures” and “nationalism,” data were drawn from a survey questionnaire given to 343 music teachers (155 preservice and 188 in-service music teachers) and semistructured interviews with 36 of these respondents.FindingsThe findings of the study showed that though many respondents in Hong Kong and Taiwan felt comfortable teaching traditional Chinese music, they did not want to teach contemporary Mainland Chinese music and other political or patriotic forms in the school music curriculum. The data also demonstrated some shortcomings in introducing a balance of music types into the curriculum, as well as limitations in promoting national education in response to the respective sociopolitical situations in Hong Kong and Taiwan.Research limitations/implicationsThis study was subject to limitations regarding the potential generalizability of the findings on school music teachers' perceptions in Hong Kong and Taiwan.Practical implicationsThe implications for teachers and student teachers regarding the development of cultural and national values related to the political processes in Hong Kong and Taiwan are complicated, because of not only their relationship with Mainland China and its education based on nationalism but also the extent of teachers' professional training to help create an enabling environment for national and cultural development.Originality/valueThe findings of this study revealed that there are fundamental gaps in the overt and operational curricula in Hong Kong and Taiwan concerning the sociopolitical function of values in school music education in response to their respective sociopolitical situations.

Published: July 2020

PurposeEntrepreneurship Education (EE) is increasing throughout the world. In 2012, the Italian Ministry of Education, University and Research (MIUR) financed Contamination Labs (CLabs), which are laboratories that are aimed at developing entrepreneurial mindsets in all university students. This study analyses the entrepreneurial learning process mechanisms adopted in these CLabs.Design/methodology/approachAn ethnographic case study was performed in two Italian CLabs from October 2017 to December 2019.FindingsFindings demonstrate that the CLabs in Italy are promising Entrepreneurship Education Centres which create programmes to develop an entrepreneurial mindset in students with different educational backgrounds and levels. Interdisciplinarity in the composition of the student teams, virtuous contamination of knowledge and experience between the students and the stakeholders from the entrepreneurial ecosystem are the key pillars to foster an entrepreneurial mindset in all the students.Research limitations/implicationsThe limitations of this work regard the need to expand the analysis to all the other CLabs created in Italian universities.Practical implicationsThe findings provide indications that may be used to guide a university faculty in the design and management of Entrepreneurship Education Centres in collaboration with entrepreneurs, corporations, student clubs, incubators and representatives of the local entrepreneurial ecosystem. Moreover, the results point out a need to develop interdisciplinary entrepreneurial programmes.Originality/valueThe originality resides in the analysis of a novel type of Entrepreneurship Education Centre in Italian Universities created as the result of an ad-hoc Italian policy.
Large-scale economic load dispatch using squirrel search algorithm
Authors: V.P. Sakthivel , M. Suman , P.D. Sathya 
Published: July 2020

PurposeEconomic load dispatch (ELD) is one of the crucial optimization problems in power system planning and operation. The ELD problem with valve point loading (VPL) and multi-fuel options (MFO) is defined as a non-smooth and non-convex optimization problem with equality and inequality constraints, which obliges an efficient heuristic strategy to be addressed. The purpose of this study is to present a new and powerful heuristic optimization technique (HOT) named as squirrel search algorithm (SSA) to solve non-convex ELD problems of large-scale power plants.Design/methodology/approachThe suggested SSA approach is aimed to minimize the total fuel cost consumption of power plant considering their generation values as decision variables while satisfying the problem constraints. It confers a solution to the ELD issue by anchoring with foraging behavior of squirrels based on the dynamic jumping and gliding strategies. Furthermore, a heuristic approach and selection rules are used in SSA to handle the constraints appropriately.FindingsEmpirical results authenticate the superior performance of SSA technique by validating on four different large-scale systems. Comparing SSA with other HOTs, numerical results depict its proficiencies with high-qualitative solution and by its excellent computational efficiency to solve the ELD problems with non-smooth fuel cost function addressing the VPL and MFO. Moreover, the non-parametric tests prove the robustness and efficacy of the suggested SSA and demonstrate that it can be used as a competent optimizer for solving the real-world large-scale non-convex ELD problems.Practical implicationsThis study has compared various HOTs to determine optimal generation scheduling for large-scale ELD problems. Consequently, its comparative analysis will be beneficial to power engineers for accurate generation planning.Originality/valueTo the best of the authors’ knowledge, this manuscript is the first research work of using SSA approach for solving ELD problems. Consequently, the solution to this problem configures the key contribution of this paper.

Authors: Kyytsönen Maiju , Tomietto Marco , Huhtakangas Moona , Kanste Outi 
Published: July 2020

PurposeThe purpose of this study is to review research on hospital-based shared governance (SG), focussing on its core elements.Design/methodology/approachA scoping review was conducted by searching the Medline (Ovid), CINAHL (EBSCO), Medic, ABI/INFORM Collection (ProQuest) and SveMed+ databases using SG and related concepts in hospital settings as search terms (May 1998–February 2019). Only original research articles examining SG were included. The reference lists of the selected articles were reviewed. Data were extracted from the selected articles by charting and then subjected to a thematic analysis.FindingsThe review included 13 original research articles that examined SG in hospital settings. The studied organizations had implemented SG in different ways, and many struggled to obtain satisfactory results. SG was executed within individual professions or multiple professions and was typically implemented at both unit- and organization-levels. The thematic analysis revealed six core elements of SG as follows: professionalism, shared decision-making, evidence-based practice, continuous quality improvement, collaboration and empowerment.Practical implicationsAn SG framework for hospital settings was developed based on the core elements of SG, the participants and the organizational levels involved. Hospitals considering SG should prepare for a time-consuming process that requires belief in the core elements of SG. The SG framework can be used as a tool to implement and strengthen SG in organizations.Originality/valueThe review resumes the tradition of systematically reviewing SG literature, which had not been done in the 21st century. General tendencies of the research scene and research gaps are pointed out.
