Published: November 2022

Purpose
This study aims to enhance to corrosion protection of NiZn-plated steel by electroplating multilayer coating.

Design/methodology/approach
The multilayer coating consists of three layers on mild steel substrate, such as Cr3+ chromate conversion layer (CCC), electrodeposited nanosilica zinc-nickel composite layer (ZnNiSi) and electrodeposited zinc-nickel alloy layer (ZnNi). Its morphology, composition and corrosion behaviour were investigated by various methods.

Findings
Polarization curves indicated that polarization resistance and corrosion current density of CCC/ZnNiSi/ZnNi/Fe (6.956 kO.cm2; 2.56 µA.cm−2) were two times higher and five times lower than that of ZnNiSi/ZnNi/Fe (3.42 kO.cm2; 12.52 µA.cm−2), respectively. From electrochemical impedance spectroscopy data, charge transfer resistances were 1.344, 2.550 and 2.312 kO.cm2 for ZnNi, ZnNiSi/ZnNi and CCC/ZnNiSi/ZnNi, respectively. Salt spray test indicated that after 48 h, surface of ZnNi and ZnNiSi was covered by white rust, whereas no white rust was observed on surface of CCC/ZnNiSi/ZnNi. After 600 h, there were red rust spots (1% surface coverage) on surface of Zn-Ni, whereas only white rust was observed on both ZnNiSi/ZnNi (100% surface coverage) and CCC/ZnNiSi/ZnNi (10% surface coverage).

Originality/value
Multilayer coating enhanced significantly the corrosion protection for steel, as compared to the single-layer coating.

Authors: Tanko Bruno Lot , Zakka Wyom Paul , Heng Wee Nie 
Published: November 2022

PurposeThe purpose of this study is to explore existing literature on Building Information Modelling (BIM) in Malaysia and examine the perception of practitioners about the potential of BIM applications in reducing construction waste and enhancing productivity.Design/methodology/approachFirst, using 244 bibliographic data extracted from the Scopus database, the paper used scientometric analysis and VOSviewer mapping technique to assess the most impactful publication literature on BIM in Malaysia to identify the existing research gaps. Second, using a structured questionnaire, a total of 100 questionnaires were distributed to practising practitioners who incorporate BIM in the delivery of their projects. Descriptive analysis using cross-tabulation in SPSS software, radar chart, relative importance index and Pearson’s correlation were used to analyze the data.FindingsThe research gaps are in the fields of construction projects, buildings, energy efficiency, lifecycle and housing. The findings of the survey indicate that quantity take-off, clash detection, site utilization planning, digital fabrication as well as 4D stimulation were the main BIM applications used among the practitioners in Johor and Selangor.Practical implicationsBy assessing the state-of-the-art of BIM and BIM applications in this region, the practical implications of this study provide useful insights to construction stakeholders, funding organizations, policymakers, research institutions, professionals, journal editors, reviewers and researchers to understand the overall trend of BIM in Malaysia and its usage.Originality/valueThis paper is the first to use science mapping using scientometrics to reveal the current BIM research in “Malaysia only”. Relying on the identified gaps, the study further examined the usage of BIM applications in Malaysian construction projects.
Contribution of business angel investments: evidence from Estonia
Authors: Kirihata Tetsuya 
Published: November 2022

PurposeThis study aims to analyze the contribution of business angels (BAs), defined as wealthy individuals who provide risk capital to entrepreneurial firms without family connections, in Estonia, an emerging country in Eastern Europe.Design/methodology/approachThis study compared the data of the financial and non-financial performance of BA-backed firms with that of “twin” non-BA-backed firms, extracted from all Estonian unlisted firms using propensity score matching.FindingsThe results of the comparative analysis showed that BAs were patient enough to allow their investees to spend for future growth rather than squeezing profit from increased sales. This is not patience without options for a BA in a situation in which the investee's sales are deteriorating, but rather deliberate patience in the presence of options for a BA where the investee's sales growth is increasing, contrary to conventional investor behavioral principles. It also showed that BAs' post-investment involvement did not make a direct contribution to their investees' sales, although BAs contributed to the sales increase through BA funding itself.Originality/valueThis study has two unique research contributions. First, it shows that the patience of BAs was not a by-product but was intentional, and adds to the debate on whether BAs are patient investors. Second, there are only a few studies on the contribution of BAs to their investees in emerging countries; this study aims to help fill this research gap using the case of Estonia.
Facile construction of flexible CC/NiS/a-NiS electrode with self-supporting structure by electroplating
Authors: Lin Xiaoping , Li Xiaoyan , Yao Jiming , Li Xianghong , Xu Jianlin 
Published: November 2022

Purpose
To develop electrode materials for supercapacitor with superior electrochemical performance and simple preparation process, the purpose of this study is to prepare flexible CC/NiS/a-NiS electrodes with self-supporting structure by loading hydrothermally synthesized a-NiS particles along with nano-NiS on carbon cloth by electroplating method.

Design/methodology/approach
The effects of current densities, temperatures and pH values on the loading amount and uniformity of the active substances during the plating process were investigated on the basis of optimization of surface morphology, crystalline structure and electrochemical evaluation as the cyclic voltammetry curves, constant current charge–discharge curves and AC impedance.

Findings
The a-NiS particles on CC/NiS/a-NiS were mostly covered by the plated nano-NiS, which behaved as a bulge and provided a larger specific surface area. The CC/NiS/a-NiS electrode prepared with the optimized parameter exhibited a specific capacitance of 115.13 F/g at a current density of 1 A/g and a Coulomb efficiency of 84% at 5 A/g, which is superior to that of CC/NiS electrode prepared by electroplating at a current density of 10 mA/cm2, a temperature of 55°C and a pH of 4, demonstrating its fast charge response of the electrode and potential application in wearable electronics.

Originality/value
This study provides an integrated solution for the development of specifically structured NiS-based electrode for supercapacitor with simple process, low cost and high electrochemical charge/discharge performance, and the simple and easy-to-use method is also applicable to other electrochemically active composites.
Do TV‐aided model lessons in class improve student performance? Evidence from public primary schools in Papua New Guinea
Authors: Shimizutani Satoshi , Taguchi Shimpei , Yamada Hiroyuki 
Published: November 2022

AbstractLack of access to high‐quality education remains a serious concern in many developing countries. This is especially the case for rural areas, including islands suffering from a shortage of skilled teachers and sufficient educational equipment. We examine the impact of introducing TV‐aided model lessons in class to enhance the quality of teaching (the EQUITV project) on the national examination test scores of Mathematics and “Combined Subject” (a comprehensive subject comprising 30% science and 70% social studies and other topics) as well as English in the final year of primary education in Papua New Guinea. We employ a panel event study to capture the different timings of the intervention across schools over multiple time periods. We find that the project significantly and robustly improved test scores for girls only in English 3 years after the introduction of the project, but no improvement was seen for boys.
Research use and publishing diversity: The role of organisation research publishing for policy and practice
Authors: Lawrence Amanda 
Published: November 2022

AbstractDigital technologies have enhanced the capacity for organisations across many sectors to produce, publish, and disseminate research in a variety of formats, and a great deal of it is sought and used in public policy and practice‐related research, yet this diversity is often overlooked in studies of research use. While the need for diverse research sources and formats for public policy and practice is increasingly acknowledged, there have been few studies which articulate and categorise what this diversity looks like in practice, and how research is filtered and selected based on genre, source, and other facets. This article reports on a large‐scale online survey and semi‐structured interviews with research users across multiple sectors in Australia on the materials they access and use for policy and practice work. The results indicate that research users are active information seekers who require online access to diverse genres and formats produced by a range of sources and sectors. However, respondents also faced many barriers to research use, including the cost of subscriptions for academic journals, discoverability of reports and data, poor management of publications by organisations including government, and the time required for filtering and evaluation. Based on these findings I argue that policy research requires a far greater variety of genres and sources than is generally recognised with implications for the way research use and the research publishing system is understood and managed in Australia.Points for practitioners
Policy research and implementation requires diverse online sources and resources from multiple sectors, including reports, discussion papers, evaluations, and data, produced by organisations (grey literature), as well as journals and books.
However, this paper finds there are major barriers to discovery, filtering, and access to diverse research publications for practitioners, resulting in poor productivity and policy outcomes.
To improve the use of evidence for policy and practice, we must invest in efficient discovery, access, and management systems for diverse research publications.
Balancing the Books: Valuing Household Work in Weimar Germany
Authors: Taratko Carolyn 
Published: November 2022

AbstractThis article explores the way that bourgeois women academics and social reformers adopted the quantified language of economics to advance their own position in the Weimar Republic. As statistics and indices proliferated as measures of national recovery, women attempted to record and describe their own economic realities within the household. They promoted bookkeeping as an indispensable tool of household rationalisation. This article argues that these bookkeeping practices enabled prominent women, including Henriette Fürth, Alice Salomon and Erna Meyer, to delineate the household – in its role as both economic unit and unit of reproductive and care work – as a site of economic importance and a field of intervention in the nascent social welfare state. Furthermore, the article shows how in the 1920s and 1930s, the market intruded into domestic life to shape notions of value and worth.

Published: November 2022

AbstractThis study aimed to investigate the composition, structure, in vitro antioxidant, and hypoglycemic activities of a novel water‐soluble MBP‐1, an extract from millet bran, isolated by DEAE‐52 cellulose and purified by Sephadex G‐100. The results showed that MBP‐1 was mainly composed of xylose, mannose, galactose, rhamnose, and arabinose with a molar ratio of 0.72:0.59:76.26:1.04:0.83 and a molecular weight of 6.6×104 Da, and its purity was 98%, and the yield was 3.76%. MBP‐1 has an irregular granular structure by atomic force microscopy and scanning electron microscopy, and the anomeric carbon in MBP‐1 molecule has α‐configuration and β‐configuration by NMR and FTIR. The in vitro scavenging abilities of MBP‐1 for·OH, DPPH, O2·−, and ABTS+ were 73.5%, 80%, 69.8%, and 75.2%, respectively, and the chelating activity for Fe2+ was 50%, and the inhibition rates of α‐glucosidase and α‐amylase were 78.5% and 74.6%, respectively, which indicated that MBP‐1 possessed strong antioxidant and hypoglycemic activities. The results indicated that MBP‐1 have certain application prospects in food‐related fields.

Published: November 2022

AbstractPorokeratosis encompass a group of acquired and familial, preneoplastic, keratinization disorders, clinically characterized by atrophic macules or patches with a peripheral keratotic rim, the cornoid lamella. Genetic background is recognized as crucial in its pathophysiology, while immunosuppression and ultraviolet radiation represent triggering factors. We report the case of a woman who developed disseminate superficial actinic porokeratosis following the intake of hydroxyurea for a polycythaemia vera. Clinical, dermoscopic and histopathology data are showed, and the role of drug as a second‐hit mutation trigger is discussed.
Job characteristics, job attitudes and employee withdrawal behaviour: A latent change score approach
Authors: van Ruysseveldt Joris , van Dam Karen , Verboon Peter , Roberts Anouk 
Published: November 2022

AbstractEmployee withdrawal is a critical issue for organisations and has been the topic of extensive research. Although much turnover research used between‐person designs, this study focused on the impact of within‐person changes in job characteristics on job attitudes and withdrawal behaviour, using the challenge‐hindrance stressor as our main theoretical framework. The focus was on the job characteristics workload (a challenge stressor), emotional demands (a hindrance stressor) and autonomy (a job resource) and on positive (dedication) and negative (organisational cynicism) job attitudes as process variables. Latent change score modelling based on data of 1530 Dutch employees collected in three waves across 2 years showed that changes in workload, emotional demands and autonomy resulted in changes in organisational cynicism, which, in turn, related to changes in turnover intentions, but not absenteeism. Changes in autonomy were related to changes in dedication, which, in turn, were associated with changes in turnover intentions, but not absenteeism. This study highlights the importance of investigating within‐person changes in job characteristics in explaining changes in job attitudes and employee withdrawal behaviour. From a practical perspective, this study shows how job design affects dedication and organisational cynicism and hence can contribute to combat employee withdrawal behaviour.
The impact of government partisanship on social policy in a young democracy: The case of South Korea
Authors: Kim Won Sub , Yu Jin‐Sook , Nam Yuncheol 
Published: November 2022

AbstractThis article investigates the impact of government partisanship on social policy developments in South Korea. Social policy developments of the center‐left Kim Dae‐Jung government and the conservative Lee Myung‐Bak government are compared using mixed quantitative and qualitative methods. The comparison demonstrates that each government is distinctive in its welfare expenditures as well as welfare ideology and reforms. The welfare reforms instituted by the Kim government strengthened the social security‐centered welfare state. In contrast, the Lee government commoditized labor and strengthened the free market logic in the welfare delivery system. Despite the impacts of partisanship, both governments dealing with economic crises and interacting with social movements were required to expand social policy. Consequently, the policy differences between the governments turned out to be less pronounced than expected. This article suggests that the party difference theory, which considers socioeconomic and political constraints, could explain crucial parts of social policy outputs in South Korea.

Published: November 2022

AimNon‐vitamin K antagonist oral anticoagulants (NOACs) are increasingly preferred over vitamin K antagonists (VKAs) in atrial fibrillation (AF) management. However, differences in oral anticoagulant (OAC) prescribing according to patient's age, sex and physician's specialty may be present. Therefore, incident and prevalent use of OACs, NOACs and VKAs, stratified by age, sex and prescriber, and factors associated with the choice of OAC were investigated.MethodsUsing two Belgian nationwide healthcare databases, AF patients ≥45 years old with ≥1 OAC prescription claim between 2013 and 2019 were identified. OAC use was investigated per half‐year. Factors influencing NOAC vs. VKA initiation were identified by multivariable logistic regression.ResultsAmong 448 661 included OAC‐treated AF patients, 297 818 were newly treated. Incident OAC use ranged from 45–49 to 42–44 users/10 000 persons between 2013 and 2019, whereas prevalent OAC use increased from 337 to 435 users/10 000 persons. Incident and prevalent NOAC use exceeded VKA use since 2013 and 2015, respectively, and NOACs represented 92% of incident and 81% of prevalent OAC users in 2019. Apixaban was the most frequently used NOAC since 2016. NOACs were significantly more prescribed by cardiologists and to older patients, whereas VKAs were more initiated in patients with cardiovascular, renal and hepatic comorbidities. Prevalent OAC use increased less in women than men (25.3% vs. 33.0% between 2013 and 2019) and female subjects had 5% significantly lower odds of NOAC vs. VKA initiation than men.ConclusionSince 2013, prevalent anticoagulant use increased almost one third in Belgium, while incident use was stable. Potential (N)OAC underuse in women requires further exploration.
Response to the ISSCR guidelines on human–animal chimera research
Authors: Koplin Julian J. 
Published: November 2022

AbstractThe International Society for Stem Cell Research (ISSCR) has recently released the 2021 update of its guidelines. The update includes detailed new recommendations on human–animal chimera research. This paper argues that the ISSCR recommendations fail to address the core ethical concerns raised by neurological chimeras—namely, concerns about moral status. In minimising moral status concerns, the ISSCR both breaks rank with other major reports on human–animal chimera research and rely on controversial claims about the grounds of moral status that many people will rightly reject. A more robust framework for regulating human–animal chimera research still needs to be developed.

Published: November 2022

Background and PurposePharmacological intervention to induce browning of white adipose tissue provides a promising anti‐obesity therapy. The fruits of Garcinia cambogia (Clusiaceae) have been widely applied to manage body weight; however, the chemical principles remain unclear. The current study aims to discover browning inducers from the fruits of G. cambogia and investigate the underlying mechanisms.Experimental ApproachThe bioactivity‐based molecular networking and Oil Red O staining on 3T3‐L1 and C3H10T1/2 adipocytes were applied for guided isolation. High‐fat diet‐induced obese mice were recruited to evaluate the anti‐obesity activity.Key ResultsThe bioactivity‐based molecular networking‐guided isolation yielded several polycyclic polyprenylated acylphloroglucinols from the fruits of G. cambogia with lipid‐lowering effect in adipocytes, including guttiferone J (GOJ), garcinol and 14‐deoxygarcinol. As the most potent one, GOJ (10 μM) reduced lipid accumulation by 70% and 76% in 3T3‐L1 and C3H10T1/2 adipocytes, respectively. Furthermore, GOJ (2.5–10 μM) increased the expression of the deacetylase sirtuin 3 (SIRT3) and activated it, which, in turn, reduced the acetylation level of PPARγ coactivator‐1α to boost mitochondrial biogenesis and promoted uncoupling protein 1 expression to enhance thermogenesis, resulting in browning of adipocytes. In high‐fat diet‐induced‐obese mice, GOJ (10 and 20 mg·kg−1·day−1 for 12 weeks) protected against adiposity, hyperlipidaemia, insulin resistance and liver lipotoxicity, through boosting SIRT3‐mediated browning of inguinal adipose tissue.Conclusion and ImplicationsGOJ represents a new scaffold of thermogenic inducer, which is responsible for the anti‐obesity property of G. cambogia and can be further developed as a candidate for treating obesity and its related disorders.
