ABSTRACTThe application of machine learning (ML) tools in electronic health records (EHRs) can help reduce the underdiagnosis of dementia, but models that are not designed to reflect minority population may perpetuate that underdiagnosis. To address the underdiagnosis of dementia in both Black Americans (BAs) and white Americans (WAs), we sought to develop and validate ML models that assign race-specific risk scores. These scores were used to identify undiagnosed dementia in BA and WA Veterans in EHRs. More specifically, risk scores were generated separately for BAs (n=10K) and WAs (n=10K) in training samples of cases and controls by performing ML, equivalence mapping, topic modeling, and a support vector-machine (SVM) in structured and unstructured EHR data. Scores were validated via blinded manual chart reviews (n=1.2K) of controls from a separate sample (n=20K). AUCs and negative and positive predictive values (NPVs and PPVs) were calculated to evaluate the models. There was a strong positive relationship between SVM-generated risk scores and undiagnosed dementia. BAs were more likely than WAs to have undiagnosed dementia per chart review, both overall (15.3% vs 9.5%) and among Veterans with >90thpercentile cutoff scores (25.6% vs 15.3%). With chart reviews as the reference standard and varied cutoff scores, the BA model performed slightly better than the WA model (AUC=0.86 with NPV=0.98 and PPV=0.26 at >90thpercentile cutoff vs AUC=0.77 with NPV=0.98 and PPV=0.15 at >90th). The AUCs, NPVs, and PPVs suggest that race-specific ML models can assist in the identification of undiagnosed dementia, particularly in BAs. Future studies should investigate implementing EHR-based risk scores in clinics that serve both BA and WA Veterans.
A model for information security culture with creativity and innovation as enablers – refined with an expert panel
Authors: Da Veiga Adéle 
Published: February 2023

Purpose
This study aims to elicit an understanding of creativity and innovation to enable a totally aligned information security culture. A model is proposed to encourage creativity and innovation as part of the information security culture.

Design/methodology/approach
The study first applied a theoretical approach with a scoping literature review using the preferred reporting items for systematic reviews and meta-analyses method to propose a conceptual model for engendering employee creativity and innovation as part of the information security culture. A qualitative research method was further applied with expert interviews and qualitative data analysis in Atlas.ti to validate and refine the conceptual model.

Findings
A refined and validated information security culture model enabled through creativity and innovation is presented. The input from the expert panel was used to extend the model by 18 elements highlighting that the risk appetite of an organisation defines how much creativity and innovation can be tolerated to reach a balance with the potential risks it might introduce. Embedding creativity and innovation as part of the organisational culture to facilitate it further as part of the information security culture can aid in combating cyber threats and incidents; however, it should be managed through a decision-making process while governed within policies that define the boundaries of creativity and innovation in information security.

Research limitations/implications
The research serves as a point of reference for further research about the influence of creativity and innovation in information security culture which can be investigated through structural equation modelling.

Practical implications
This study offers novel insights for managerial practice to encourage creativity and innovation as part of information security.

Originality/value
The research proposes a novel concept of introducing creativity and innovation as part of the information security culture and presents a novel model to facilitate this.
Effects of vividness, information and aesthetic design on the appeal of pay-per-click ads
Authors: Zhu Ying , Wang Yong , Wei Joicey , Hao Andy 
Published: February 2023

PurposeFew studies illustrate how contextual effects (e.g. assimilation and contrast) in pay-per-click ad design may impact consumers' attitudes and purchase intention. To fill this research gap, the authors provide theoretical predictions and empirical evidence on how ad design may prompt an assimilation and/or a contrast effect that may influence consumers' attitudes toward the ad and the brand and purchase intention. They also investigate whether the impact of contextual effects on consumers' decisions depends on the level of vividness in the ad.Design/methodology/approachA 2 (vividness: dynamic motion vs. static page) × 2 (information design: assimilation vs. contrast) × 2 (aesthetic design: assimilation vs. contrast) between-subjects experimental design is used to examine the effects of vividness, information design and aesthetic design. Conditional process analysis is used to assess the mediating role of attitudes toward the ad and the brand in the relationship between contextual effects and purchase intention.FindingsFor dynamic ads (i.e. high vividness) but not for static ads (i.e. low vividness), combined information contrast and aesthetic contrast designs generate a more favorable attitude toward the brand and a higher purchase intention than do combined information assimilation and aesthetic assimilation designs. Notably, combined information contrast and aesthetic contrast designs have the strongest effects than any other combination of assimilation and contrast designs of information and aesthetics. Attitudes toward the ad and the brand are significant mediators between contextual factors and intention to purchase.Research limitations/implicationsThe study examines the effectiveness of online ads from a new theoretical angle based on the attributes of pay-per-click ads.Practical implicationsThe results suggest that when advertisers decide to use dynamic ads, they should adopt a contrast design for both the ad information and its aesthetics.Originality/valueThis study fills a research gap in the contextual effects literature, including providing evidence of an underlying process in the relationship between certain contextual effects and purchase intent. It also extends previous findings of assimilation/contrast in information design to aesthetics design and advances the literature on vividness by examining a moderation effect of vividness.
Balancing patent portfolios and R&D efforts: examining firm performance
Authors: Kim Zhunwoo , Lee Duk Hee , Choi Kyu-Sun , Kwon Ohsung 
Published: February 2023

PurposeThis study aims to ascertain whether technological diversification (TD) enhances firm performance and explores the effect of patent portfolio balancing (PPB) on firm financial performance and the moderating role of research and development (R&D) intensity.Design/methodology/approachThis study empirically investigates a panel dataset based on 296 information and communications technology (ICT) small and medium-sized enterprises (SMEs) over 5 years, using a fixed-effects panel regression with time-lagged and moderating effects. Data are collected from a government survey and a firm and patent database.FindingsThe relationship between PPB and return on assets (ROA) is negative, indicating that TD in SMEs adversely affects firm performance. R&D intensity positively moderates the relationship between PPB and ROA, implying that follow-up R&D after creating new patents could weaken the negative relationship between TD and firm performance. This moderating effect only occurs when R&D intensity is sufficiently high, suggesting that high R&D firms could be more successful at diversification.Practical implicationsAs TD consumes many resources, managers should set the optimal level of diversification and recognise the need for follow-up R&D for successful diversification.Originality/valueThis study conceptualises a unique theoretical framework for the PPB of ICT SMEs, revealing the moderating role of R&D intensity in changing the negative influence of PPB on firm performance.

Authors: Wonnie Ma Iling Aema , Ong Gerard , Shafaamri Ammar , Jamalludin Julie Nabilah , Ishun Nina Nazirah , Kasi Ramesh , Subramaniam Ramesh 
Published: February 2023

Purpose
This study aims to fabricate the acrylic-based polymeric composite coating with a hydrophobic surface associated with natural oil polyol (NOP) and polydimethylsiloxane with the incorporation of 3 Wt.% SiO2 nanoparticle (SiO2np) against the corrosive NaCl media.

Design/methodology/approach
The structural properties of the formulated polymeric composite coatings were investigated by using Fourier transform infrared spectroscopy, ultraviolet-visible spectroscopy, water contact angle (WCA) and cross-hatch (X-Hatch) tests. The WCA measurement was used to study the surface wettability of the formulated polymeric composite coatings. The corrosion protection performance of the nanocomposite coated on the mild steel substrate was studied by immersing the samples in 3.5 Wt.% NaCl solution for 30 days using electrochemical impedance spectroscopy.

Findings
The enhanced polymeric composite coating system performed with an excellent increase in the WCA up to 111.1° which is good hydrophobic nature and very high coating resistance in the range of 1010 Ω attributed to the superiority of SiO2np.

Originality/value
The incorporation of SiO2np into the polymeric coating could enhance the surface roughness and hydrophobic properties that could increase corrosion protection. This approach is a novel attempt of using NOP along with the addition of SiO2np.
A novel hierarchical temperature control method of an electric oven and its experimental evaluation
Authors: Shokri Kalandaragh Yaser , Sabahi Kamel 
Published: February 2023

Purpose
Ovens are semi-industrial multipurpose equipment that are used to provide a desired temperature for specific chemical processes. Temperature regulation in the presence of different type of disturbances and dealing with nonlinear dynamics with large dead time (up to a few minutes) are some undesirable factors that have to be considered in the controller design procedure of the oven systems. Due to these factors, the classical PID controller tuned using Cohen-Coon or Ziegler–Nichol’s tuning methods often fails to meet satisfactory closed-loop performance.

Design/methodology/approach
In this paper, to deal with the limitations on the oven system due to the undesirable factors, a hierarchical automaton-guided form controller has been designed. The proposed controller includes several discrete PI controllers, each of which operates locally in the defined operating regions whose separation idea is specific to this paper. Based on the idea proposed in the separation of regions, the controller’s coefficients tuning rules are extracted prior to any determination. Then, a supervisor controller has assumed the task of switching between local controllers. In the next step, by considering a conceptual model for the oven system and using a candidate Lyapunov function, the stability conditions of closed-loop system are discussed and the necessary conditions for the asymptotic stability are derived. The proposed controller is practically implemented with the help of the Arduino Nano platform.

Findings
Using several experiments, the superiority of the proposed hierarchical controller in terms of performance and energy consumption has been demonstrated.

Originality/value
The proposed hierarchical controller has been implemented practically and an acceptable closed-loop performance has been achieved. To illustrate the efficiency of the proposed method, the closed-loop stability of this method is shown using the Lyapunov theory.

Authors: Indarwati Retno , Fauziningtyas Rista , Jalaludin Nur Sayyid , Fauziah Anis , Efendi Ferry 
Published: February 2023

Purpose
Older adults living in nursing homes may become vulnerable because of errors or incidents; it is necessary to create a positive safety culture to minimise such occurrences. However, safety culture is still a prevailing issue in Indonesian nursing homes. This study aims to examine factors related to resident safety culture in nursing homes located in Indonesia.

Design/methodology/approach
This study used a cross-sectional research design and involved 13 nursing homes in East Java province, Indonesia. Multistage cluster samplings were used to determine the respondents of this study. The respondents included 219 employees: managers, health care, supportive and administrative staff. The Indonesian version of the Safety Attitudes Questionnaire was used to measure safety culture.

Findings
Most of the respondents (68.5%) had a positive perspective on the nursing home’s safety culture. Staffs who had worked for six to ten years in the nursing home were 17.07 times more likely to have positive perspective on safety culture with a p-value of 0.0002. Respondents who gave direct care also had a positive perception of safety culture with a p-value of 0.008.

Research limitations/implications
Broader insight into safety culture needs to be provided to all staff in the nursing home. Safety topics should be included in the orientation session for new staff.

Originality/value
The staff’s work experience and direct care have a significant connection to safety culture.
JobKeeper: An Initial Assessment
Authors: Borland Jeff , Hunt Jennifer 
Published: February 2023

AbstractWe present details of the design and implementation of the 2020–2021 JobKeeper program and review the literature on its impacts. JobKeeper stimulated the macroeconomy and restrained job loss in the downturn. But because the program was not narrowly targeted, the cost per job saved was high and the impact most likely regressive. However, it would not have been possible to devise and implement a more targeted program in the available time, and as it was, JobKeeper was arguably implemented later than needed for maximum effectiveness. We therefore recommend that Australia consider establishing a short‐time work program for use in future recessions.
Constructing the detecting stage: Social processes and the diagnostic journey of early onset Parkinson’s disease
Authors: Valasaki Maria 
Published: February 2023

AbstractParkinson’s is a neurodegenerative disorder that mostly affects people over the age of 65; however, a significant number (10%) of the diagnosed cases are under the age of 50 (Young Onset Parkinson’s disease). It has multiple symptoms; it is difficult to diagnose and its progression cannot be intercepted. This article focuses on the experience of the diagnostic process as narrated by individuals who were under the age of 50 when diagnosed. Analysis of in‐depth interviews with 17 individuals with Parkinson’s disease inductively reveals a ‘detecting stage’, a period during which they visit different doctors, undertake many examinations and experience bodily symptoms with impacts on their mental health. The diagnostic process, which usually lasts over 2 years, often leads to misdiagnosis and or late diagnosis (a) on account of the individual’s young age and social meanings attached to it, usually by doctors, whose discourse appears to be rather psychologised and (b) is perceived as disruptive to individuals’ biographies. Due to the tendency to over‐attribute bodily symptoms to psychological problems, accurate diagnosis is experienced as redemption.

Published: February 2023

AbstractObjectiveWe aimed to investigate the effect of targeted therapies on cardiovascular risk in psoriasis (PsO) and psoriatic arthritis (PsA) via a meta‐analysis of randomized controlled trials (RCTs).MethodsPubmed, Embase, Cochrane Library, and Scopus were searched for RCTs reporting targeted therapies in patients with PsO/PsA published until 28 October 2021. The primary and secondary outcomes included the relationship between targeted therapies and all cardiovascular events (CVEs), major adverse cardiovascular events (MACEs), myocardial infarction (MI), heart failure, and stroke in PsO/PsA. The outcome risk ratios (RRs) were calculated using the Mantel–Haenszel fixed‐effect method.ResultsA total of 81 articles involving 88 RCTs were included. There was no statistically significant difference regarding the occurrence of all CVEs for all targeted therapies (RR = 1.03, 95% CI 0.74‐1.43, P = .85) compared to placebo in PsO/PsA. No statistically significant difference existed between drugs and placebo in patients with PsA on all CVEs (RR = 0.81, 95% CI 0.48‐1.36, P = .43). Surprisingly, the incidence of all CVEs was higher in the low dosage group compared to the high dosage group of all targeted therapies (RR = 1.97, 95% CI 1.19‐3.27, P = .008) and prominently anti‐interleukin‐17 agent (RR = 2.20, 95% CI 1.05‐4.58, P = .04).ConclusionCurrent targeted therapies are not associated with the risk of CVEs. Based on the existing evidence, we reported here that a dosage reduction of targeted therapies was not recommended.

Published: February 2023

AbstractBackgroundEmergence agitation is a common clinical condition in children. Symptoms pertaining to the spectrum of early postoperative negative behavior typically occur upon emergence from anesthesia. Clonidine is an effective adjunctive agent for the prevention of emergence agitation in children, but evidence in the smallest age groups is sparse We aim to investigate the efficacy and safety of an intraoperative bolus of intravenous clonidine for preventing emergence agitation in children 3–12 months of age.MethodsThis is a randomized, placebo‐controlled, double‐blind trial. We will enroll 320 patients aged 3–12 months who have been scheduled for general anesthesia maintained with sevoflurane and opioid. The randomization is parallel and stratified by age group, sex, and site. The investigational medicinal product will be administered intravenously ~20 min before the anticipated end of the surgical procedure. The intervention is clonidine 3 μg/kg and placebo is isotonic saline in a corresponding volume.ResultsThe primary outcome is the incidence of emergence agitation as assessed on the Watcha scale, that is, any Watcha score >2 during participants' stay in the postanesthetic care unit. Secondary outcomes are the proportion of participants with postoperative pain, with postoperative nausea and vomiting, and a composite safety outcome. Statistical analysis will be conducted according to the Statistical Analysis Plan with the intention‐to‐treat population for our primary analyses.ConclusionThe PREVENT AGITATION II trial will contribute valuable knowledge on efficacy for the prevention of emergence agitation and safety in infants.

AbstractObjectiveTo investigate student supervisor experiences of supervising students on clinical placements since the onset of the COVID‐19 pandemic.BackgroundStudies on the impact of COVID‐19 on student clinical placements have focused largely on student reports and have been specific to individual professions or topic areas. There is a need to investigate student supervisor experiences. This study was conducted in Queensland (Australia) in four regional and rural public health services and four corresponding primary health networks.MethodsThe anonymous, mixed methods online survey, consisting of 35 questions, was administered to student supervisors from allied health, medicine, nursing and midwifery between May and August 2021. Numerical data were analysed descriptively using chi‐square tests. Free‐text comments were analysed using content analysis.ResultsComplete datasets were available for 167 respondents. Overall trends indicated perceived significant disruptions to student learning and support, plus mental health and well‐being concerns for both students and supervisors. Extensive mask wearing was noted to be a barrier to building rapport, learning and teaching. Some positive impacts of the pandemic on student learning were also noted.ConclusionsThis study has highlighted the perceived impact of the pandemic on supervisors' mental health, and on the mental health, learning and work readiness of students. This study provides evidence of the pandemic impacts on student clinical placements from a supervisor point of view. Findings can assist in future‐proofing clinical education and ensuring that students continue to receive learning experiences of benefit to them, meeting curriculum requirements, in the event of another pandemic.
Medical student interest and participation in research at one rural clinical school: Insights from the last six years
Authors: Fox Jordan L. , Cribb Jacky , Cumming Kaye , Martin Priya 
Published: February 2023

AbstractIntroductionLimited evidence is currently available relating to research acitivity of medical students training in regional or rural areas.ObjectiveTo describe medical student interest and participation in research at The University of Queensland Rural Clinical School (UQRCS).DesignAnnual student expression of interest surveys were collated with records of student research participation maintained at UQRCS from 2017‐2022. Additionally, a systematic search was conducted to identify student outputs not captured in internal records. Frequencies and proportions were calculated for all descriptive data along with proportions of students who engaged with a project, and projects that led to a peer‐reviewed publication.FindingsAt UQRCS commencement, 55% of research‐interested students reported having basic research skills. Thirty‐nine percent of research‐interested students engaged with a project, most commonly literature reviews (47%) or audits (29%). Thirty‐three percent of completed projects led to a peer‐reviewed manuscript.DiscussionStudents who engage with a project are unlikely to receive a project in their preferred clinical area and should be informed about the transferrability of research skills. Most students have basic research skills when commencing a project and therefore require ongoing support and mentorship from staff/supervisors.ConclusionPublication rates of medical students in regional/rural areas are comparable to those reported by metropolitan medical schools (~30%).
