Research on the cooperative train control method in the metro system for energy saving
Authors: Li Siyao , Yuan Bo , Bai Yun , Liu Jianfeng 
Published: September 2023

PurposeTo address the problem that the current train operation mode that train selects one of several offline pre-generated control schemes before the departure and operates following the scheme after the departure, energy-saving performance of the whole metro system cannot be guaranteed.Design/methodology/approachA cooperative train control framework is formulated to regulate a novel train operation mode. The classic train four-phase control strategy is improved for generating specific energy-efficient control schemes for each train. An improved brute force (BF) algorithm with a two-layer searching idea is designed to solve the optimisation model of energy-efficient train control schemes.FindingsCase studies on the actual metro line in Guangzhou, China verify the effectiveness of the proposed train control methods compared with four-phase control strategy under different kinds of train operation scenarios and calculation parameters. The verification on the computation efficiency as well as accuracy of the proposed algorithm indicates that it meets the requirement of online optimisation.Originality/valueMost existing studies optimised energy-efficient train timetable or train control strategies through an offline process, which has a defect in coping with the disturbance or delays effectively and promptly during real-time train operation. This paper studies an online optimisation of cooperative train control based on the rolling optimisation idea, where energy-efficient train operation can be realised once train running time is determined, thus mitigating the impact of unpredictable operation situations on the energy-saving performance of trains.

AbstractPsoriasis is a chronic, refractory inflammatory skin disease, with a high prevalence of psychiatric comorbidities, including depression, anxiety, and even suicidality, which may in turn initiate or exacerbate skin inflammation. However, the causal relationships between these comorbidities remain unclear. To investigate the cause–effect relationships between psoriasis and mental disorders including depression, anxiety, and suicidality, we conducted a bidirectional two‐sample Mendelian randomization (MR) study utilizing summary statistics from the most comprehensive genome‐wide association studies of psoriasis (n = 306 123), broad depression (n = 500 199), major depressive disorder (n = 173 005), anxiety (n = 17 310), and suicide attempts (n = 50 264). Using the random‐effects inverse‐variance weighted method as primary method, the forward MR analyses indicated that psoriasis was significantly associated with higher odds of broad depression (odds ratio [OR] 1.030, 95% confidence interval [CI] 1.010–1.051, P = 0.003) and suggestively associated with an increased risk of major depressive disorder (OR 1.054, 95% CI 1.002–1.109, P = 0.040), but not with the risk of anxiety (P = 0.160) or suicide attempts (P = 0.648). In reverse MR analyses, significant causal impact of broad depression (OR 1.363, 95% CI 1.103–1.684, P = 0.004) and major depressive disorder (OR 1.890, 95% CI 1.285–2.781, P = 0.001), but not anxiety (P = 0.787) and suicide attempts (P = 0.961) on psoriasis risk was observed. In addition, the results of primary analysis are consistent across sensitivity analyses, albeit the MR–Egger regression model produced wide CIs and negative results in several analyses. In conclusion, this MR study indicates a bidirectional causal relationship between psoriasis and depression that was previously unrecognized, which highlights the significance of screening for depression in psoriasis patients and initiating appropriate interventions. Further studies are required to elucidate the pathophysiology of the bidirectional causal relationship between these two conditions.

AbstractMicroorganisms can facilitate the reduction of Cu2+, altering its speciation and mobility in environmental systems and producing Cu‐based nanoparticles with useful catalytic properties. However, only a few model organisms have been studied in relation to Cu2+ bioreduction and little work has been carried out on microbes from Cu‐contaminated environments. This study aimed to enrich for Cu‐resistant microbes from a Cu‐contaminated soil and explore their potential to facilitate Cu2+ reduction and biomineralisation from solution. We show that an enrichment grown in a Cu‐amended medium, dominated by species closely related to Geothrix fermentans, Azospira restricta and Cellulomonas oligotrophica, can reduce Cu2+ with subsequent precipitation of Cu nanoparticles. Characterisation of the nanoparticles with (scanning) transmission electron microscopy, energy‐dispersive x‐ray spectroscopy and electron energy loss spectroscopy supports the presence of both metallic Cu(0) and S‐rich Cu(I) nanoparticles. This study provides new insights into the diversity of microorganisms capable of facilitating copper reduction and highlights the potential for the formation of distinct nanoparticle phases resulting from bioreduction or biomineralisation reactions. The implications of these findings for the biogeochemical cycling of copper and the potential biotechnological synthesis of commercially useful copper nanoparticles are discussed.
Authentic leadership, psychological capital, acceptance of change, and innovative work behaviour in non‐profit organisations
Authors: Brunetto Yvonne , Kominis Georgios , Ashton‐Sayers Julia 
Published: September 2023

AbstractThis paper examines whether authentic leadership provides the resources employees need to build their psychological capacities and well‐being so that they can embrace organisational change and engage in innovative work behaviour (IWB) within non‐profit organisation (NPO). The paper builds on previous research examining the antecedents of IWB such as ‘innovation‐enabling culture’ and psychological capital (PsyCap). The new variables examined in this study are authentic leadership and acceptance of change. Utilising a structural equation modelling methodology, 248 surveys from Australian not‐for‐profit employees were analysed revealing that authentic leadership accounted for more than a fifth of the variance of PsyCap; PsyCap, age, and authentic leadership accounted for 40% of employees’ well‐being; and age, leadership, and acceptance of change accounted for a quarter of their IWB, although acceptance of change was not directly related to IWB. The main contribution of this paper is in explaining why authentic leadership is an important ingredient for building an ‘innovation‐enabling culture’ for NPO employees, suggesting that such leadership provides a pathway for developing effective workplace relationships built on trust and ethical decision making. Such behaviour builds a supportive culture for developing employees’ personal resources, which promotes the conditions for promoting IWB.Points for practitioners
Authentic leadership behaviour provides a platform for developing the psychological capacities of employees in non‐profit organisations (NPOs) contracted to deliver social services to Australians.
Authentic leadership behaviours and psychological capital enhance employees’ well‐being.
Authentic leadership behaviours and psychological capital are significant building blocks of an innovation‐enabling culture in NPOs.
What influences public decision‐makers? An Australian case study
Authors: Bolton Mitzi 
Published: September 2023

AbstractLimited or incomplete achievement of societal aspirations, such as the realisation of sustainable development, can lead to distrust in government and the public sector. This paper takes an empirical approach to uncover (1) what factors influence public decision‐makers, (2) if such factors apply equally irrespective of the decision, and (3) which are most important. Thirty‐five interviews of public servants within the subnational State of Victoria, Australia, yield 40 common influences upon decision‐makers. Collectively, these influences result in an unmanageably complex operating environment. Statistical and network mapping analyses further demonstrate decision context and decision‐maker self‐efficacy impact influence importance.Points for practitioners
Forty different influences make the public sector operating environment incredibly complex; they explain why public outcomes can deviate from stated objectives.
These influences vary in impact (barriers, enablers), scale, and importance, pending the decision context and the self‐efficacy of the decision‐makers involved.
While distinct factors, the 40 influences often operate in concert, with some masking others; decision‐makers themselves may not recognise the most important factors upon their work without deep reflection.
Far from being at the mercy of the influences, decision‐makers can shape public outcomes by recognising the influences on their decisions and seeking to engage them as enablers of optimal decisions.
Applying systems thinking may enable widespread public decision‐making improvements, through the identification of high‐value leverage points.
What motivates users to adopt cybersecurity practices? A survey experiment assessing protection motivation theory

Published: September 2023

AbstractResearch SummaryA 2 × 2 × 3 fully crossed factorial experiment is used to examine the linkages between key dimensions of protection motivation theory (PMT; perceived severity of risk, vulnerability to risk, and response costs) and the intentions to adopt information technology (IT) cybersecurity recommendations after being informed of degrees of risk in the vignettes. Data in this study consist of a nationwide sample of 720 American adults. Results from a series of fractional logistic regressions indicate support for many of the core mechanisms within PMT. Seventy percent of respondents indicated they were likely to follow IT recommendations to mitigate a cyber threat. Self‐efficacy and response costs affected intentions to do so.Policy ImplicationsThe study's findings have important implications for improving cybersecurity and reducing vulnerabilities to cyber threats. Current training programs need more effective communication strategies and engagement tools. Perceptions of users as security threats rather than potential contributors hinder progress in the ability of organizations to improve cybersecurity. Collaborative, user‐centered approaches can enhance users’ self‐efficacy and improve cybersecurity by aligning user and IT professional needs and capabilities. Strategies like gamified simulations and tailored interventions can create a more security‐focused culture and encourage user participation in defending an organization. Recognizing individual differences among users and further examining personal characteristics that may impact user interactions with technology and cybersecurity interventions is crucial. Overall, more personalized, adaptable approaches to cybersecurity policies and technical solutions, accounting for diverse user needs and characteristics, should be a priority for improving cybersecurity practices.

AbstractInstitutional authority and responsibility for allocating water to ecosystems (“ecologically available water” [EAW]) is spread across local, state, and federal agencies, which operate under a range of statutes, mandates, and planning processes. We use a case study of the Upper Missouri Headwaters Basin in southwestern Montana, United States, to illustrate this fragmented institutional landscape. Our goals are to (a) describe the patchwork of agencies and institutional actors whose intersecting authorities and actions influence the EAW in the study basin; (b) describe the range of governance mechanisms these agencies use, including laws, policies, administrative programs, and planning processes; and (c) assess the extent to which the collective governance regime creates gaps in responsibility. We find the water governance regime includes a range of nested mechanisms that in various ways facilitate or hinder the governance of EAW. We conclude the current multilevel governance regime leaves certain aspects of EAW unaddressed and does not adequately account for the interconnections between water in different parts of the ecosystem, creating integrative gaps. We suggest that more intentional and robust coordination could provide a means to address these gaps.

AbstractProteomic approaches have unique advantages in the identification of biological pathways that influence physical frailty, a multifactorial geriatric syndrome predictive of adverse health outcomes in older adults. To date, proteomic studies of frailty are scarce, and few evaluated prefrailty as a separate state or examined predictors of incident frailty. Using plasma proteins measured by 4955 SOMAmers in the Atherosclerosis Risk in Community study, we identified 134 and 179 proteins cross‐sectionally associated with prefrailty and frailty, respectively, after Bonferroni correction (p < 1 × 10−5) among 3838 older adults aged ≥65 years, adjusting for demographic and physiologic factors and chronic diseases. Among them, 23 (17%) and 82 (46%) were replicated in the Cardiovascular Health Study using the same models (FDR p < 0.05). Notably, higher odds of prefrailty and frailty were observed with higher levels of growth differentiation factor 15 (GDF15; pprefrailty = 1 × 10−15, pfrailty = 2 × 10−19), transgelin (TAGLN; pprefrailty = 2 × 10−12, pfrailty = 6 × 10−22), and insulin‐like growth factor‐binding protein 2 (IGFBP2; pprefrailty = 5 × 10−15, pfrailty = 1 × 10−15) and with a lower level of growth hormone receptor (GHR, pprefrailty = 3 × 10−16, pfrailty = 2 × 10−18). Longitudinally, we identified 4 proteins associated with incident frailty (p < 1 × 10−5). Higher levels of triggering receptor expressed on myeloid cells 1 (TREM1), TAGLN, and heart and adipocyte fatty‐acid binding proteins predicted incident frailty. Differentially regulated proteins were enriched in pathways and upstream regulators related to lipid metabolism, angiogenesis, inflammation, and cell senescence. Our findings provide a set of plasma proteins and biological mechanisms that were dysregulated in both the prodromal and the clinical stage of frailty, offering new insights into frailty etiology and targets for intervention.
Life years lost for users of specialized mental healthcare

Published: September 2023

AbstractBackgroundMental disorders are burdensome and are associated with increased mortality. Mortality has been researched for various mental disorders, especially in countries with national registries, including the Nordic countries. Yet, knowledge gaps exist around national differences, while also relatively less studies compare mortality of those seeking help for mental disorders in specialized mental healthcare (SMH) by diagnosis. Additional insight into such mortality distributions for SMH users would be beneficial for both policy and research purposes. We aim to describe and compare the mortality in a population of SMH users with the mortality of the general population. Additionally, we aim to investigate mortality differences between sexes and major diagnosis categories: anxiety, depression, schizophrenia spectrum and other psychotic disorders, and bipolar disorder.MethodsMortality and basic demographics were available for a population of N = 10,914 SMH users in the north of The Netherlands from 2010 until 2017. To estimate mortality over the adult lifespan, parametric Gompertz distributions were fitted on observed mortality using interval regression. Life years lost were computed by calculating the difference between integrals of the survival functions for the general population and the study sample, thus correcting for age. Survival for the general population was obtained from Statistics Netherlands (CBS).ResultsSMH users were estimated to lose 9.5 life years (95% CI: 9.4–9.6). Every major diagnosis category was associated with a significant loss of life years, ranging from 7.2 (95% CI: 6.4–7.9) years for anxiety patients to 11.7 (95% CI: 11.0–12.5) years for bipolar disorder patients. Significant differences in mortality were observed between male SMH users and female SMH users, with men losing relatively more life years: 11.0 (95% CI: 10.9–11.2) versus 8.3 (95% CI: 8.2–8.4) respectively. This difference was also observed between sexes within every diagnosis, although the difference was insignificant for bipolar disorder.ConclusionThere were significant differences in mortality between SMH users and the general population. Substantial differences were observed between sexes and between diagnoses. Additional attention is required, and possibly specific interventions are needed to reduce the amount of life years lost by SMH users.
Evidence collection and use when making management decisions
Authors: Criado‐Perez Christian , Jackson Chris , Collins Catherine G. 
Published: September 2023

AbstractEvidence‐based management (EBM) is a useful framework to assist managers in making organizational decisions based on the best available evidence. EBM use is nevertheless marginal among managers, and little is known about the enablers that can facilitate and effectively increase its use. We use two experimental studies to examine the effect of cognitive reflection, learning goals, and social norms in predicting EBM usage. We also propose an objective assessment task to measure the collection and use of evidence in the context of EBM. Results from both studies provide support for the importance of cognitive reflection and social norms to enable EBM. Surprisingly, learning goals were not associated with EBM use. This research increases our understanding of EBM, provides indications of how to increase its usage, and presents a methodology to investigate evidence collection and use objectively.

Published: September 2023

AbstractPortable X‐ray fluorescence (pXRF) geochemical analysis on obsidian from five Formative period (1200 BCE to AC 100) sites from Tlaxcala, Mexico, has revealed that most of the material had similar values to those found in the closest obsidian source, named El Paredón, Puebla. Nevertheless, initial analyses did not resolve whether these materials came from the same caldera or from a specific obsidian deposit. Here we present a methodology that allows the identification of obsidian subsources. The results reveal that Tlaxcalan populations took advantage of a specific obsidian deposit called Tres Cabezas, Puebla, providing valuable new data to identify associated regional exchange networks.

Published: September 2023

AbstractThis study gives the element compositions and Pb isotope ratios of three lead ingots and three bronze artefacts unearthed from Yinxu, Anyang, Henan province, and two lead vessels from Zhengxiaozhuang tomb, Anhui province, China. The results of composition analysis show that three lead ingots in Yinxu may be the primary product of lead smelting. The lead wares unearthed in Zhengxiaozhuang tomb could be a kind of Mingqi‐funerary replicas. The results of Pb isotope analysis indicate that the culture exchanges between the Central Plains and the Jianghuai area in the late Shang dynasty. The decrease of bronzes with the highly radiogenic lead is consistent with the increase of Pb content in Yinxu bronzes simultaneously, which could be related to the change of lead source.

AbstractPrevious studies have established the use of various blue pigments, including both local and imported varieties, in the decoration of architecture in ancient China. However, the application of these pigments in local religious architecture has been understudied. In this study, the chemical analysis of ultramarine blue pigments was conducted on a mural painting retrieved from Yongle Taoist Temple in ancient China. The results showed that both imported and local pigments were used individually in the initial drawing period of the Yuan Dynasty (AD 1271–1368), whereas they were mixed in a later restoration in the Qing Dynasty (AD 1636–1912). Of particular significance, the analysis revealed the presence of lapis lazuli in a local religious relic of the Yuan Dynasty for the first time. Further analysis of the elemental proportions and associated minerals led to speculation about the origin of the lapis lazuli, which is believed to have come from Badakhshan, the northeastern region of Afghanistan, and been transported to Central China through the Silk Road. This finding shed light on the trade routes and usage of these pigments in the construction of religious architecture from the Yuan to the Qing dynasties.
Decolonising ecological research: A generative discussion between Global North geographers and Global South field ecologists

Published: September 2023

AbstractIn this article we draw on recent debates in ecology and human geography on the project of decolonising academic practice. Our objective is to address two key questions via a generative discussion across disciplines: what can ecologists learn from ongoing debates in human geography? And how might those learnings translate back into geographical praxis? We make the central argument that vibrant debates in human geography can push ecologists to take more radical steps towards a decolonial vision that, in turn, can guide geographers to a more material decolonising praxis. We build this argument by working through various dis/connections—between ecology/human geography, theory/praxis, South/North—in the wider project of decolonising academia to provoke critical reflection around the themes of (i) language and publishing; (ii) collaboration and ‘inclusion’; and (iii) the geographies of ecological research.
