Evidence assessment and narrative synthesis of the key characteristics of older people living in service-integrated housing facilities, and their ‘accommodation journey’
Authors: Thompson Juliana , Hill Michael , Bainbridge Lesley , Cowie Daniel , Flewers Emma 
Published: November 2021

Purpose
This paper aims to provide an evidence assessment and narrative synthesis of literature regarding the key characteristics of older people living in service-integrated housing (SIH) facilities and their “accommodation journey”.

Design/methodology/approach
A rapid evidence assessment was conducted: 22 research publications met the inclusion criteria and were analysed using narrative synthesis.

Findings
The quality of studies in this area is low, but consistency across components of the results of studies included in the review is apparent. Results suggest key characteristics of older people that drive moves into SIH are a decline in health, increased dependency, increased health service use and carer burden. Suggested key characteristics of SIH residents are high levels of health problems, dependency and health service use, but high self-reported health and well-being. Results indicate that the key driver for older people leaving SIH is a lack of workforce competency to manage further declines in health and dependency status.

Research limitations/implications
Current policy may not realise or account for the complex health and care needs of SIH residents. Investment into integrated care, robust community health services and workforce development to facilitate a comprehensive assessment approach may be required to support residents to remain in SIH and live well. Further longitudinal studies are required to map the progression of SIH residents’ health status in detail over time to provide an understanding of preventative and enablement support, development of care pathways and workforce planning and development requirements.

Originality/value
This evidence assessment is the first to consider the accommodation journey of older people residing in SIH.
Aboriginal knowledge, the history classroom and the Australian university
Authors: Musgrove Nell , Wolfe Naomi 
Published: November 2021

PurposeThis article considers the impact of competing knowledge structures in teaching Australian Indigenous history to undergraduate university students and the possibilities of collaborative teaching in this space.Design/methodology/approachThe authors, one Aboriginal and one non-Aboriginal, draw on a history of collaborative teaching that stretches over more than a decade, bringing together conceptual reflective work and empirical data from a 5-year project working with Australian university students in an introductory-level Aboriginal history subject.FindingsIt argues that teaching this subject area in ways which are culturally safe for Aboriginal and Torres Strait Islander staff and students, and which resist knowledge structures associated with colonial ways of conveying history, is not only about content but also about building learning spaces that encourage students to decolonise their relationships with Australian history.Originality/valueThis article considers collaborative approaches to knowledge transmission in the university history classroom as an act of decolonising knowledge spaces rather than as a model of reconciliation.

Published: November 2021

PurposeThe purpose of this paper is to university students' awareness of the employers preferred competencies and the educational level capable of readying them satisfactory for the demands of the world of work.Design/methodology/approachUsing a qualitative approach exploratory research design, data were gathered in an informal and unstructured manner, researchers identified undergraduate students' awareness of employers' preferred competencies of the graduates.FindingsUndergraduate students overestimated academic credentials while ignoring soft skills as employers' preferences. Nevertheless, they were worried about their capability to compete adequately when seeking employment despite identifying university level of education as the most appropriate for developing and enhancing their employability.Research limitations/implicationsThe study involved mostly second-year students from one college of the seven colleges constituting the University of Dodoma.Practical implicationsThere is a need for university education to integrate and emphasize the non-cognitive skills for adequately and holistically preparing future employees with adequate knowledge and skills to thrive in the world of work demands.Social implicationsThere likelihood that a lack of confidence would impact their participation in academia and work/job. Hence, lower down their productivity and inadequately contribute to social and national economic growth.Originality/valueThe value of these findings is that they identify, inform and can be used to enhance university education programming for improved graduate's employability.
Fully-developed laminar flow in trapezoidal ducts with rounded corners: a numerical solution and case study
Authors: Ismail Mohammed S. , Berber Mohamed R. , Alrowaili Ziyad A. , Pourkashanian Mohamed 
Published: November 2021

Purpose
This paper aims to numerically solve fully developed laminar flow in trapezoidal ducts with rounded corners which result following forming processes.

Design/methodology/approach
A two-dimensional model for a trapezoidal duct with rounded corners is developed and conservation of momentum equation is solved. The flow is assumed to be steady, fully developed, laminar, isothermal and incompressible. The key flow characteristics including the Poiseuille number and the incremental pressure drop have been computed and tabulated for a wide range of: sidewall angle (θ); the ratio of the height of the duct to its smaller base (α); and the ratio of the fillet radius of the duct to its smaller base (β).

Findings
The results show that Poiseuille number decreases, and all the other dimensionless numbers increase with increasing the radii of the fillets of the duct; these effects were found to amplify with decreasing duct heights or increasing sidewall angles. The maximum axial velocity was shown to increase with increasing the radii of the fillets of the duct. For normally used ducts in hydrogen fuel cells, the impact of rounded corners cannot be overlooked for very low channel heights or very high sidewall angles.

Practical implications
The data generated in this study are highly valuable for engineers interested in estimating pressure drops in rounded trapezoidal ducts; these ducts have been increasingly used in hydrogen fuel cells where flow channels are stamped on thin metallic sheets.

Originality/value
Fully developed laminar flow in trapezoidal ducts with four rounded corners has been solved for the first time, allowing for more accurate estimation of pressure drop.
Modelling the thermal state of a turbocharger bearing housing when calculating the rotor dynamics at transient modes
Authors: Zadorozhnaya Elena , Hudyakov Vladislav , Polyacko Elizaveta , Dolgushin Igor 
Published: November 2021

Purpose
The reliability of various mechanisms and machines is determined by the durability of tribo-units, which must ensure operation at high temperatures and an extended range of rotor shaft speeds. The best performance of the bearing assembly is achieved with hydrodynamic lubrication, which depends on optimal operating conditions and temperature conditions. The purpose of this paper is determining the thermal state of the turbocharger (TCR) bearings.

Design/methodology/approach
The simulation was carried out in the ANSYS Fluent software package. The boundary conditions for the calculation were obtained from experimental data. The experiments were carried out at a specialized stand created at the scientific and production association “Turbotekhnika”.

Findings
The result of the simulation was the determination of temperatures and thermal fields in the TCR housing. The data obtained testify to the uneven thermal loading of the bearings. When calculating the dynamics of the rotor, transient modes are considered. The results are the trajectories of the rotor in the space of the bearing clearance. The thickness of the lubricating layer was calculated as a parameter that determines the hydrodynamic friction regime. The thermal state of the TCR elements was evaluated at all the considered rotor speeds. The flexible axis of the rotor was obtained at different speeds.

Originality/value
The paper presents a model of heat transfer in a TCR housing and rotor dynamics, based on numerical methods, which will help in the design of TCRs and journal bearings.
Analysis of leakage characteristics for bent-axis piston pump based on elastohydrodynamic deformation
Authors: Qing Lvjun , Gu Lichen , Wang Yan , Lei Zhufeng 
Published: November 2021

Purpose
This paper aims to revel the leakage characteristics of the bent-axis piston pump considering elastohydrodynamic deformation via a dynamic leakage model.

Design/methodology/approach
A dynamic leakage model of bent-axis piston pump based on elastohydrodynamic lubrication theory is proposed, which is used to present the leakage characteristics of bent-axis piston pump. The model is composed of three parts. First, the dynamic gap in the piston ring-cylinder bore interface (PRCB) is described via the elastohydrodynamic lubrication equations. Then, the PRCB leakage is presented based on the dynamic gap. Finally, combined with leakage equation of the valve plate-cylinder block interface (VPCB), the total leakage model is proposed. Through the numerical simulation and experiment, the leakage characteristics of bent-axis piston pump considering elasto-hydrodynamic deformation are studied.

Findings
The PRCB leakage is negatively correlated with VPCB leakage under the range of 800–1400 r/min and 1–25 MPa. When the discharge pressure is less than the critical pressure, the PRCB leakage is the main factor affecting the total leakage in bent-axis piston pump. On the contrary, the VPCB leakage is the main factor. The critical pressure increases with increasing speed

Originality/value
The effect of operating parameters has a significant effect on the elastic deformation of piston ring without considering wear of friction pairs in bent-axis piston pump. There is a critical phenomenon in the leakage, which is related to the operating parameters, and provides a novel idea for extracting wear information from leakage and evaluating the status of bent-piston pump.

Published: November 2021

PurposeThis paper aims to unpack the relationship between the interactive use of project control systems (PCS) and project performance by examining the role of stakeholder analysis effectiveness in enacting this relationship. A conceptual framework was developed based on the stakeholder theory and the levers of control framework.Design/methodology/approachPartial least square-structural equation modelling analysis was conducted on the cross-sectional questionnaire data collected from 109 information technology (IT) projects.FindingsThe interactive use of PCS enables project managers to effectively deal with the stakeholders-related uncertainty, and stakeholder analysis effectiveness partially mediates the positive relationship between the interactive use of PCS and IT project performance.Originality/valueThis study extends the project control literature by explaining the positive relationship between the interactive use of PCS and project performance. The findings contribute to the stakeholder analysis literature by operationalizing the stakeholder analysis effectiveness construct and identifying it as a new mediator between the interactive use of PCS and project performance.

Published: November 2021

PurposeAfter more than 18 months of life during a pandemic, much of the world is beginning to transition back to some semblance of normalcy. As that happens, institutions – including policing – need to acknowledge changes that had been made during the pandemic and decide what modifications and innovations, if any, to continue moving forward.Design/methodology/approachThe authors use semi-structured interviews and focus groups of police personnel in the United States (US) and Canada. The sample includes police officers and frontline supervisors (n = 20). The authors conduct qualitative analysis using deductive and inductive coding schemes.FindingsThe sample identified four areas of adaptation during the pandemic: 1) safety measures, 2) personnel reallocation, 3) impacts on training and 4) innovation and role adjustments. These areas of adaptation prompted several recommendations for transitioning police agencies out of the pandemic.Originality/valueA growing number of studies are addressing police responses to the pandemic. Virtually all are quantitative in nature, including all studies investigating the perceptions of police personnel. The body of perceptual studies is extraordinarily small and primarily focuses on police executives, ignoring the views of the rank-and-file who are doing the work of street-level police business. This is the first study to delve into the perceptions of this group, and does so using a qualitative approach that permits a richer understanding of the nuances of perception.
Frequency‐dependent signal‐to‐noise ratio effect of distributed acoustic sensing vertical seismic profile acquisition
Authors: Alzamil Nour , Li Weichang , Zhou Hua‐Wei , Merry Harold 
Published: November 2021

ABSTRACTDistributed acoustic sensing provides seismic sensors distributed every few metres over each fibre optic cable of several kilometres in length, serving as an ultra‐dense array for both surface and downhole seismic acquisitions. It is well‐recognized now that distributed acoustic sensing acquisition configuration can have profound effect on data quality, notably the choice of the gauge length and lead‐in cable length on the resulting signal to noise ratio. In this paper, we present a detailed study on how these effects behave differently over various signalling frequency bands. We derive the signal to noise ratio as a function of the peak frequency, gauge length and lead‐in cable length, and demonstrate significantly different 80 SNR samples behaviours over low, middle and high frequency bandwidths, respectively. These results, not only reveal the underlying mechanism for signal and noise variation as function of acquisition parameters, but also help identifying the desired gauge and cable lengths that better serve particular applications, such as inversion and imaging which take information from different frequency bands. A field data has been used to demonstrate these frequency‐dependent behaviours.
Conductivity in partially saturated porous media described by porosity, electrolyte saturation and saturation‐dependent tortuosity and constriction factor
Authors: Berg Carl Fredrik , Kennedy W. David , Herrick David C. 
Published: November 2021

ABSTRACTModelling the relationships among bulk conductivity, electrolyte conductivity, porosity and fractional electrolyte‐saturation continues to be based on empirical relationships such as Archie's law or the Bruggeman correlation. Several authors have attempted to connect such empirical models to first principles. This article presents a complete first principles‐based description of conductivity in partially saturated porous media. A geometrical factor is introduced which, together with porosity and saturation, describes the conductivity of partially saturated porous media. This geometrical factor is separated into two intrinsic geometrical descriptors of the electrolyte distribution accounting for tortuosity and constriction. This tortuosity and constriction factor are obtained from integration over the electrical field lines traversing the electrolyte. Bulk and saturation‐dependent conductance descriptions are illustrated using three‐dimensional pore space models and simulated fluid distributions. Describing conductance through porosity, saturation and a geometrical factor, decomposed into separate terms accounting for tortuosity and constrictivity, permits more insightful understanding of conductance in partially saturated porous media. Use and efficacy of this full conductance description is illustrated throughout this article.
Reducing disease and producing food: Effects of 13 agrochemicals on snail biomass and human schistosomes

Published: November 2021

Abstract

Agricultural expansion is predicted to increase agrochemical use two to fivefold by 2050 to meet food demand. Experimental evidence suggests that agrochemical pollution could increase snails that transmit schistosomiasis, a disease impacting 250 million people, yet most agrochemicals remain unexamined.

Here we experimentally created >100 natural wetland communities to quantify the relative effects of fertilizer, six insecticides (chlorpyrifos, terbufos, malathion, λ‐cyhalothrin, permethrin and esfenvalerate), and six herbicides (acetochlor, alachlor, metolachlor, atrazine, propazine and simazine) on two snail genera responsible for 90% of global schistosomiasis cases.

We identified four of six insecticides (terbufos, permethrin, chlorpyrifos and esfenvalerate) as high risk for increasing snail biomass by reducing snail predators. Hence, malathion and λ‐cyhalothrin might be useful for improving food production without increasing schistosomiasis. This top‐down effect of insecticides on predators was so strong that the effects of herbicides on schistosomiasis risk were masked in the presence of predators because there were so few snails. In the absence of snail predators, herbicide effects on snails were generally negative by reducing submerged vegetation Hydrilla verticillata. The exception was that atrazine and acetochlor significantly increased the biomass of infected snails and total snails respectively.

Like insecticides, fertilizer had strong positive effects on snail populations. Fertilizer increased both snail habitat (submerged vegetation) and snail food (periphyton), but of these two pathways, the increases in snail habitat resulted in greater snail population growth. Total snail biomass was positively associated with both infected snail biomass and parasite production and thus human infection risk.

Synthesis and applications. Our findings suggest that fertilizers and insecticides generally have consistently higher chances of increasing human schistosomiasis than herbicides in natural communities. Furthermore, our results highlight the need to identify other low risk insecticides, which might help reduce crop pests without increasing snails and thus risk of schistosomiasis.

AbstractIntroductionQuantitative measurement of anti‐A/‐B antibody titers is important during ABO‐incompatible living kidney transplantation (ABOi‐LKT).MethodsWe conducted a multi‐institutional study to measure the antibody titers using the automated column agglutination technique (auto‐CAT) and tube test (TT) method in ABOi‐LKT recipients. Statistical analysis was performed to evaluate the two methods.ResultsWe examined 111 samples from 35 ABOi‐LKT recipients at four institutions. The correlation coefficient of the two methods was >0.9; the concordance rate and clinically acceptable concordance rate for the IgG titers were 60.4% and 88.3%, respectively. Perioperative status did not influence the statistical significance. Parallel changes were observed in the IgG antibody titers measured using the auto‐CAT or TT technique by desensitizing therapy in time‐course monitoring.ConclusionAuto‐CAT is comparable with the TT technique and is feasible for IgG anti‐A/B antibody titration in ABOi‐LKT recipients.

AbstractBackgroundThe efficacy and safety of rituximab (RTX) for lupus nephritis are still a controversial issue.MethodsWe systematically searched MEDLINE, EMBASE, and the Cochrane Library databases for all clinical controlled studies.ResultsSix studies with 588 patients were included in our meta‐analysis. RTX increased total renal remission rates (TR, odds ratio [OR] 2.16, 95% CI 1.31 to 3.55, P = .003) and complete renal remission rate (CR, OR 2.42, 95% CI 1.18 to 4.94, P = .02) compared with the control group. Subgroup analyses showed that rituximab was more effective at increasing the rate of TR and CR for lupus nephritis patients compared with mycophenolate mofetil (TR, OR 4.6, 95% CI 1.29 to 16.47, P = .02; CR, OR 2.56, 95% CI 1.19 to 5.47, P = .02) and cyclophosphamide (TR, OR 2.89, 95% CI 1.31 to 6.40, P = .009; CR, OR 2.75, 95% CI 1.19 to 6.4, P = .02). Rituximab also had advantage in reducing Systemic Lupus Erythematosus Disease Activity Index score (–2.49, 95% CI –3.77 to –1.22, P = .0001). There were no significant differences between the RTX group and control group on the change of proteinuria (–0.36 g/d, 95% CI –0.71 to –0.00 g/d, P = .05) and serum creatinine (0.13 mg/dL, 95% CI –0.15 to 0.42 mg/dL, P = .36). RTX treatment did not increase the risk of adverse events compared to the control group.ConclusionsThis study provides clear beneficial effects of RTX in patients with lupus nephritis. In addition, RTX therapy did not increase the risk of adverse events compared to the control group.

AbstractBackgroundRapid intraoperative diagnosis for unconfirmed pulmonary tumor is extremely important for determining the optimal surgical procedure (lobectomy or sublobar resection). Attempts to diagnose malignant tumors using mass spectrometry (MS) have recently been described. This study evaluated the usefulness of MS and artificial intelligence (AI) for differentiating primary lung adenocarcinoma (PLAC) and colorectal metastatic pulmonary tumor.MethodsPulmonary samples from 40 patients who underwent pulmonary resection for PLAC (20 tumors, 20 normal lungs) or pulmonary metastases originating from colorectal metastatic pulmonary tumor (CRMPT) (20 tumors, 20 normal lungs) were collected and analyzed retrospectively by probe electrospray ionization‐MS. AI using random forest (RF) algorithms was employed to evaluate the accuracy of each combination.ResultsThe accuracy of the machine learning algorithm applied using RF to distinguish malignant tumor (PLAC or CRMPT) from normal lung was 100%. The algorithms offered 97.2% accuracy in differentiating PLAC and CRMPT.ConclusionsMS combined with an AI system demonstrated high accuracy not only for differentiating cancer from normal tissue, but also for differentiating between PLAC and CRMPT with a short working time. This method shows potential for application as a support tool facilitating rapid intraoperative diagnosis to determine the surgical procedure for pulmonary resection.
