Authors: Wang Wenting , Jian Lirong , Guo Qiuyun , Zhang Haitao , Liu Wenxing 
Published: December 2020

PurposeThe purpose of this study is to build a link between narcissistic supervision and employees' change-oriented organizational citizenship behaviors (OCBs). On the basis of the social dynamics of state paranoia theory, the study examines the relationship between narcissistic supervision and employees' change-oriented OCBs, and explores how this relationship is mediated by psychological safety and affective organizational commitment.Design/methodology/approachUsing data collected from a sample of 183 employee–leader dyads from a technology company in China, the study examines the mediating effects of psychological safety and affective organizational commitment on the relationship between narcissistic supervision and employees' change-oriented OCBs. Structural equation modeling is used to analyze the data.FindingsThe results indicate that narcissistic supervision has a negative effect on psychological safety and affective organizational commitment; psychological safety mediates the relationship between narcissistic supervision and affective organizational commitment; and affective organizational commitment mediates the relationship between psychological safety and employees' change-oriented OCBs. The results also show that the negative effect of narcissistic supervision on employees' change-oriented OCBs is mediated by psychological safety and subsequently affective organizational commitment.Originality/valueThis study contributes to the literature by linking narcissistic supervision and employees' change-oriented OCBs and suggesting that psychological safety and affective organizational commitment are two critical mediators of this relationship. This study not only advances research on the “dark side” of narcissistic supervision, but also sheds light on the underlying mechanism of narcissistic supervision and employees' change-oriented OCBs from the psychological and emotional perspectives.
Mental health consequences of COVID-19 pandemic on adult population: a systematic review
Authors: Raihan Mohammad Mojammel Hussain 
Published: December 2020

Purpose
The spread of novel coronavirus 2019 (COVID-19) has infected millions of people worldwide. Public health emergencies caused by COVID-19 affect not only people’s physical health but also mental health. This paper aims to summarize recent research findings on the mental health impact of COVID-19 experienced by the general adult population.

Design/methodology/approach
This paper used a systematic approach and aimed to review the literature on mental health problems faced by general adults during the COVID-19 pandemic. The PubMed database has been selected randomly from the Google Scholar, Cochrane Library, Embase and PubMed databases. Ten journal articles published between January and July 2020 were selected from the PubMed database for the final review.

Findings
There is growing evidence that COVID-19 may be an objective risk factor for mental distress among the general adult population. More psychological and social support should be provided to protect adult people’s mental health.

Practical implications
This review will help policymakers develop mental health interventions for the general adult population vulnerable to psychological distress because of COVID-19 pandemic.

Originality/value
This paper is original and contributes to the existing knowledge that the mental health challenges of COVID-19 are widespread. There is, therefore, a need for more psychological interventions for adults, older adults, in particular, to promote mental health and reduce the distress associated with public health emergencies caused by COVID-19.
Making post-colonial place identity: the regeneration of the St Lazarus neighbourhood, Macau
Authors: Ye Xi 
Published: December 2020

Purpose
This study aims to identify how the place identity of the former Portuguese neighbourhood of St Lazarus was reshaped for the purposes of place branding, tourism and consumption in post-colonial Macau.

Design/methodology/approach
This study sees place identity as a constructed multiplicity whose components are strategically assembled to (re)make the self. It uses the Deleuze–Guattarian theory of assemblage to analyse identity-making, specifically to examine how urban elements, including material content (material qualities of forms, programmes and life) and narrative expressions (interpretations of place), come together to shape the sense of place.

Findings
The heritage conservation policy and creative district planning guidance are overarching controls. Following them, several material and narrative elements are connected. The colonial character of the architecture is reinforced and an artistic atmosphere is created, while inhabitants’ everyday life is suppressed and the difficult past is almost erased. The newly processed post-colonial identity seems another kind of colonisation. Coloniality as a power relationship continues in a different form. The hidden structure driving these processes is global capitalism.

Originality/value
Studies on colonial architectural heritage in Macau, particularly outside of the UNESCO World Heritage Site, remain relatively scarce. This study aims to fill this gap and to further examine the Deleuze–Guattarian theory in the context of place study.
A robust iterative pose tracking method assisted by modified visual odometer
Authors: Yuan Rupeng , Zhang Fuhai , Fu Yili , Wang Shuguo 
Published: December 2020

Purpose
The purpose of this paper is to propose a robust iterative LIDAR-based pose tracking method assisted by modified visual odometer to resist initial value disturbance and locate a robot in the environments with certain occlusion.

Design/methodology/approach
At first, an iterative LIDAR-based pose tracking method is proposed. The LIDAR information is filtered and occupancy grid map is pre-processed. The sample generation and scoring are iterated so that the result is converged to the stable value. To improve the efficiency of sample processing, the integer-valued map indices of rotational samples are preserved and translated. All generated samples are analyzed to determine the maximum error direction. Then, a modified visual odometer is introduced for error compensation. The oriented fast and rotated brief (ORB) features are uniformly sampled in the image. A local map which contains key frames for reference is maintained. These two measures ensure that the modified visual odometer is able to return robust result which compensates the error of LIDAR-based pose tracking method in the maximum error direction.

Findings
Three experiments are conducted to prove the advantages of the proposed method. The proposed method can resist initial value disturbance with high computational efficiency, give back credible real-time result in the environment with abundant features and locate a robot in the environment with certain occlusion.

Originality/value
The proposed method is able to give back real-time pose tracking results with robustness. The iterative sample generation enables the robot to resist initial value disturbance. In each iteration, rotational and translational samples are separately generated to enhance computational efficiency. The maximum error direction of LIDAR-based pose tracking method is determined by principle component analysis and compensated by the result of modified visual odometer to give back correct pose in the environment with certain occlusion.
Momordica angustisepala fibres and ant hill particles/polyester value-added hybrid composites for bumper application
Authors: Nwuzor I.C. , C.U. Atuanya , O. Olisa 
Published: December 2020

Purpose
The production of car bumper composites based on glass fibers and carbon fibers has been a continuous trend. These materials have standard properties; however, they are very expensive and are not readily available. Therefore, focus on the choice of reinforcement fibers is gradually shifting toward natural sources. Natural fibers are becoming attractive alternatives to traditional high‐performance fibers such as glass and carbon fibers for reinforcement in composites in structural applications. To produce a car bumper that will be less expensive and available leads to the development of Momordica angustisepala fibers (MAf) and anthill particles/ polyester hybrid composites.

Design/methodology/approach
The composite was produced by hand lay method. The physical, mechanical, microstructure and thermal properties of the composites were used as criteria for the selection of the material for car bumper application. The validation of the tensile properties was done using the finite element method.

Findings
The results should impact energy of 7.82J/mm2, 145.28 per cent improvement in tensile strength of the polyester increased by the addition of 6wt per cent MAf, and 5wt per cent anthill particles. Flexural modulus of 2269.01 and 2435.19 Mpa and flexural strength of 56.61 and 85.45 Mpa were obtained for the polyester and composite. The maximum temperature of decomposition was 370.00 and 472.00oC for polyester and composite. Validation of the tensile properties shows that with the difference between predicated yield strength the experimental gave a percentage error of 6.43 per cent and safety of 68.12 per cent. It can be concluded that the composite formulation with 6 wt per cent MAf and 5 wt per cent anthill particles in polyester can be used in the production of car bumper because the mechanical properties obtained are within the ranges used for car bumper application.

Originality/value
The composition of 5 wt per cent anthill particles and 6 wt per cent MAf in polyester has never been used in the production of car bumper before now; hence this work is novel and contributed to knowledge materials development.
Accounting: the teaching, the practice and what is missing
Authors: Rajeevan Shanmugavel 
Published: December 2020

Purpose
This paper aims to identify the knowledge and practice gap in accounting education and propose an alternative teaching method to align accounting education to meet the needs of the practical world.

Design/methodology/approach
A total of 500 questionnaires were circulated among four stakeholders (academics, accounting students, accountants in business and accountants in practice) and received an overall usable response rate of 27%.

Findings
It was found that to reflect the current accounting practices, accounting students should be exposed to accounting specific experiential learning and industry specific training at an early stage of their academic education. Universities and professional institutes can work together to develop a curriculum to create an elite league of accounting professionals.

Practical implications
The insights of this study would provide guidance to educators on how to develop an advance experiential learning structure for students that reflects the current accounting practices and technologies involved.

Originality/value
This study contributes to the existing literature by means of providing an alternative teaching method for undergraduate accounting degree program.
Outcomes of Medicaid home‐ and community‐based long‐term services relative to nursing home care among dual eligibles

Published: December 2020

AbstractObjectiveTo provide the first plausibly causal national estimates of health outcomes for older dual‐eligible recipients of Medicaid HCBS relative to nursing home care and to explore possible mechanisms for the effect.Data SourcesWe use 2005 and 2012 Medicaid Analytic eXtract (MAX), a national compilation of Medicaid claims, merged with Medicare claims to identify hospital admissions, our main outcome variable.Study DesignWe model the effects of HCBS using a longitudinal instrumental variables framework. To address the endogeneity of HCBS receipt, we instrument for it using the county percentage of nonelderly long‐term care users who receive HCBS. The percentage of nonelderly users is highly predictive of HCBS use for an elderly beneficiary, but because the instrument was derived from a separate population, the exclusion restriction is unlikely to be violated.Population Studied1,312,498 older adults (65+) dually enrolled in Medicaid and Medicare and are using long‐term care. We also examine heterogeneity of effects by race/ethnicity and the presence of dementia.Principal FindingsHCBS users have 10 percentage points higher (P < .01) annual rates of hospitalization than their nursing home counterparts when selection bias is addressed; rates of potentially avoidable hospitalizations are 3 percentage points higher (P < .01). These differences persist across races, dementia status, and intensity of HCBS spending.ConclusionsShifting Medicaid long‐term care funding for older adults from nursing homes to HCBS, while well‐motivated, results in the unintended consequence of substantially higher hospitalization rates for older dual eligibles. The quality and/or quantity of services may be inadequate for some HCBS recipients. Hospitalizations are costly to Medicare but also to the HCBS recipient in terms of stress and risks. Although consumer preferences to remain at home may outweigh poor outcomes of HCBS, the full costs and benefits need to be considered. HCBS outcomes—not just expansion—need more attention.

Published: December 2020

BackgroundData on the causes of death and long‐term mortality of intensive care unit‐treated hospital survivors with acute kidney injury (AKI) are limited. The goal of this study was to analyze the causes of death among critically ill patients during a 5‐year follow‐up.MethodsIn this predetermined sub‐study of a prospective, observational, multi‐center cohort from the FINNAKI study, we analyzed 2436 patients who were discharged from the hospital. Statistics Finland provided the follow‐up data and causes of death.ResultsDuring the follow‐up, 765 (31%) patients died, of whom 295 (39%) had AKI and 73 (9.5%) had received renal replacement therapy. More than half of the deaths in both the non‐AKI and AKI groups occurred after the 1 year follow‐up (58% vs. 54%, respectively). The three most common causes of death in AKI were cardiovascular diseases (36%), malignancies (21%), and neurological diseases (11%). In early deaths (<90 days) cardiovascular causes were more prevalent in AKI patients compared to non‐AKI (38% vs 25%, P = .037.) In six cases (0.8%), the main cause of death was kidney disease, out of which five were in the AKI group. In patients with cardiovascular causes, the median time to death was shorter in AKI patients compared to non‐AKI patients (508 vs 816 days, P = .018).ConclusionCardiovascular causes and malignancies account for more than half of the causes of death in patients who had suffered AKI, while death from kidney disease after AKI is rare. Early cardiovascular deaths are more prevalent in AKI compared to non‐AKI patients.

Published: December 2020

AbstractBackgroundNasal high flow (NHF) has demonstrated efficacy in relieving dyspnea in various patients with hypoxemic and hypercapnic respiratory failure. It may also reduce dyspnea in patients with acute severe asthma in the emergency department (ED). The aim of the study was to compare the efficacy of NHF with conventional oxygen therapy (COT) in improving dyspnea in acute severe asthma patients with hypoxemia in the ED.MethodsThis pilot nonblinded randomized controlled trial was conducted involving 37 patients aged ≥ 18 years with acute severe asthma and hypoxemia in the ED of Siriraj Hospital, Bangkok, Thailand (TCTR20180926003). The participants were randomly allocated to receive either COT (n = 18) or NHF (n = 19) for 120 minutes. The primary outcome was comparing the intervention effects on the patients’ degree of dyspnea measured using the modified Borg scale (MBS). The secondary outcomes were comparing the interventions based on the numeric rating scale (NRS) of dyspnea, the dyspnea scale assessing accessory muscle use, vital signs, and blood gas results.ResultsThe intention‐to‐treat analysis included 37 patients (COT group n = 18 and NHF group n = 19). The baseline mean MBS was 7.8 in both groups. At 120 minutes, the mean (±SD) MBSs in patients receiving COT and NHF were 3.3 (±2.5) and 1.4 (±2.5), respectively (mean difference = 1.9 [95% CI = 0.2 to 3.8], p = 0.043). The trends in NRS and dyspnea score results were similar to those of MBS. Respiratory rates were lower with NHF (mean difference = 4.7 [95% CI = 1.5 to 7.8], p = 0.001). No between‐ or within‐group differences in blood gas results were found.ConclusionNasal high flow reduced the severity of dyspnea and respiratory rate in hypoxemic patients with acute severe asthma in the ED.

AbstractPurposeTo investigate whether higher blood pressure and greater arterial stiffness are associated with the presence of macular cysts and whether this association is already present in the absence of micro‐aneurysms in individuals with and without type 2 diabetes.MethodsUsing spectral domain optical coherence tomography (OCT), we performed a macular volume scan in 2647 individuals (mean age 60 ± 8 years, 50% men, 27% type 2 diabetes). The association between macular cysts and 24‐hour systolic and diastolic blood pressure, pulse pressure, mean arterial blood pressure, carotid‐femoral pulse wave velocity and carotid distensibility was assessed by use of logistic regression.ResultsTwenty‐four hours systolic blood pressure was associated with the presence of macular cysts [OR = 1.03 (95% CI 1.00–1.05) per 1 mmHg, p = 0.03]. 24 hr pulse pressure [OR = 1.61 (95% CI 1.11–2.34) per 10 mmHg, p = 0.01] and carotid‐femoral pulse wave velocity [OR = 1.16 (95% CI 1.02–1.32) per 1 m/s, p = 0.02] were associated with macular cysts, while carotid distensibility was not [OR = 1.03 (95% CI 0.96–1.11) per 1.0*10−3/kPa, p = 0.45]. Associations were similar in individuals with and without type 2 diabetes and were already present in the absence of micro‐aneurysms.ConclusionTwenty‐four hours systolic blood pressure, 24 hr pulse pressure and carotid‐femoral pulse wave velocity are associated with the presence of OCT‐detected macular cysts in individuals with and without type 2 diabetes, even in the absence of micro‐aneurysms. Therefore, blood pressure and aortic stiffness are potential factors contributing to macular cysts.
The overprotection of conscientious objection in Chile’s abortion regulation
Authors: Marshall Pablo , Zúñiga Yanira 
Published: December 2020

AbstractThis paper critically analyses conscientious objection to abortion in the context of the new regulation of pregnancy termination in Chile. It argues that adequate regulation should not be blind: The bioethical requirements that seek to balance the interests involved must consider the legal regulation of the interests at stake, the context in which they are implemented, and, fundamentally, the effectiveness of the solutions adopted. Attention should be paid to the risks involved in the political use of conscientious objection to prevent the implementation of women’s reproductive rights. In describing the process of the entrenchment and expansion of conscientious objection to abortion in Chile, we show how this process has overprotected conscience and how the risks of undermining the effectiveness of the new abortion legislation hinder the enjoyment of rights entrenched by the law.
Visions, promises and understandings of development around Kenya’s Masinga reservoir
Authors: Clelland William 
Published: December 2020

AbstractMotivationUtilitarian visions of societal transformation often drive decisions about large infrastructure projects. However, such visions mask the heterogeneity of encounters with the projects and fail to consider lasting impacts on communities whose lives they can disrupt. Further, it is seldom considered that such communities need to anticipate the future to manage the changes they will experience.PurposeThis article considers how the trajectories of change experienced by people living in the vicinity of a major infrastructure project have shaped their visions of development. In addition, it examines how interested parties (or stakeholders) can work together to look beyond the project and stimulate further development opportunities.Approach and MethodsDrawing on fieldwork at Masinga dam and reservoir in Kenya, the research privileged local experiences and longer‐term views of this hydropower development, 40 years after construction work began. A mixed‐methods research design was used to understand how Masinga reservoir and the associated development discourse have been assimilated locally.FindingsAlthough the water associated with Masinga reservoir has been accepted by a nearby community, inequitable access and poor stakeholder relations resulted in the project failing to act as a catalyst for subsequent inclusive development. Past and present conflicts over access to water and land have generated a chronic environment of distrust and short‐term, individualistic visions of development. However, when people consider how things could be then visions of community‐driven development can emerge.Policy ImplicationsFor infrastructure projects to stimulate lasting community development, the heterogeneity of encounters and longer‐term impact on both the environment and social relations must be considered. Moreover, development authorities should explicitly raise the visibility of issues faced by the full range of stakeholders. With a resurgence of interest in large hydropower schemes, policies that encourage stakeholders to develop a common vision of what lies beyond a project is critical to achieving equitable and sustainable change.
