Work interruptions and missed nursing care: A necessary evil or an opportunity? The role of nurses’ sense of controllability
Authors: Abdelhadi Nasra , Drach‐Zahavy Anat , Srulovici Einav 
Published: October 2021

AbstractAimTo explore nurses’ experiences with work interruptions (WIs) through the lens of missed nursing care (MNC).DesignA qualitative descriptive design.MethodsEleven small focus groups involving 34 nurses (three nurses per group on average) from acute‐care hospital wards were conducted. Nurses shared their experiences with WIs (sources, reactions and decisions) from the MNC perspective. Data analysis was conducted via content analysis.ResultsA preponderant theme emerged—the dynamic of controllability. Nurses who perceived a sense of controllability felt that they could decide whether to accept or reject the WI, regardless of WI type, and emotions of anger emerged. Conversely, nurses who did not perceive sense of controllability attended the secondary task: MNC occurred, and distress emotions emerged. Results emphasized that nurses are active agents prioritizing whether to omit or complete care in the face of WIs. Controllability, accompanied by active negative emotions, perpetuate a prioritization process that makes it less probable that MNC occurs.
Numerical analysis of a second order ensemble method for evolutionary magnetohydrodynamics equations at small magnetic Reynolds number
Authors: Carter John , Jiang Nan 
Published: October 2021

AbstractWe study a second order ensemble method for fast computation of an ensemble of magnetohydrodynamics flows at small magnetic Reynolds number. Computing an ensemble of flow equations with different input parameters is a common procedure for uncertainty quantification in many engineering applications, for which the computational cost can be prohibitively expensive for nonlinear complex systems. We propose an ensemble algorithm that requires only solving one linear system with multiple right‐hands instead of solving multiple different linear systems, which significantly reduces the computational cost and simulation time. Comprehensive stability and error analyses are presented proving conditional stability and second order in time convergent. Numerical tests are provided to illustrate theoretical results and demonstrate the efficiency of the proposed algorithm.

Published: October 2021

AbstractGuanxi, which literally means interpersonal relationship or social connections, plays an important role in achieving business success in China. This study investigates the effect of interpersonal relationship on trust and trustworthiness in four regions in China. Eighty pairs of close friends participated in the experiment: 20 pairs from Beijing, 20 pairs from Guangdong, 20 pairs from Shanghai, and 20 pairs from Chongqing. A cooperation experiment based on a two‐tier simulated supply chain was conducted, in which the participant who played as a supplier solicited demand forecast information from the participant who played as a retailer to plan production. Participants were instructed to perform two tasks: one with a “friend” counterpart and one with a “stranger” counterpart. The results demonstrated regional differences in the effects of interpersonal relationship on trust and trustworthiness: the effect of interpersonal relationship was greater in Guangdong than in the other regions. Additionally, a quantified classification of trustworthiness–trust was proposed by clustering analysis. The type of self‐protective trustworthiness and altruistic trust occupied an overwhelming majority in each region, followed by the type of altruistic trustworthiness and self‐protective trust, the type of altruistic trustworthiness and altruistic trust, and the type of self‐protective trustworthiness and self‐protective trust. Regional differences in the distribution proportions in the four types were discovered.
L‐glutamic acid as a versatile platform for rapid synthesis of functional polyesters via facile Passerini multicomponent polymerization

Published: October 2021

AbstractIn this work, a series of polyesters with different functional side groups were successfully prepared by Passerini three‐component polymerization (P‐3CP) in “one‐pot” from biorenewable l‐glutamic acid (l‐GA)‐based monomers. First, the polymerization conditions including monomer feed ratios, solvents and comonomer were systematically studied using Boc‐protected l‐GA with adipaldehyde and tert‐butyl isocyanide. Under the optimal polymerization conditions, a variety of N‐substituted l‐GA‐based monomers as well as functional isocyanides were attempted in the P‐3CP to produce polyesters with different functionalities. Moreover, it was found that after removal of pendant protecting groups, the obtained l‐GA‐based polyester degraded spontaneously into small molecules via 1,5‐intramolecular cyclization between the pendant amine groups and the ester groups in polymer backbone. The structures and thermal properties of obtained polymers were determined by 1H NMR, IR, SEC, MALDI‐ToF‐MS, DSC, and TGA measurements. Starting from biorenewable l‐GA, this approach will provide a facile and straightforward route to produce functional and biodegradable polyesters, thus effectively expanding the range of biodegradable polymers.
A structural criterion for simulation of optimalion‐stimulated plasma growth of chained carbon
Authors: Buntov Evgeny , Arslanov Kirill 
Published: October 2021

AbstractThe low‐dimensional carbon allotropes have become a prominent topic of research due to their unprecedented strength and prospective physical properties. The Ar+ ion‐stimulated plasma deposition of the one‐dimensional carbon chains always presented a challenging task that still lacks a theoretical description. In this study, we propose a selective deposition quality criterion for the massive simulations planned to reveal the conditions for the synthesis of carbyne‐containing films, in particular, linear‐chained carbon by means of molecular dynamics.

Published: October 2021

AbstractBACKGROUNDMigration is a widespread phenomenon among many insect species, including herbivorous crop pests. At present, scant information exists on the long‐range migration of the polyphagous armyworm, Spodoptera exigua and its underlying climatic determinants (i.e. East Asian or South Asian monsoon circulation). In this study, we employed a population genetics approach to delineate S. exigua migration patterns across multiple Asian countries.RESULTSUsing mitochondrial cytochrome I (COI) and microsatellite markers, low‐to‐moderate levels of genetic diversity were detected among 101 S. exigua populations collected across China, Pakistan and Vietnam. Haplotype diversity and nucleotide diversity did not differ between years. Two spatially explicit genetic clusters were detected, an eastern and a western clade, with the former comprising populations in the East Asia monsoon area. No genetic differentiation was recorded among armyworm populations in the year‐round breeding area, nor among those of the overwintering and nonoverwintering areas. Five of the most widespread mitochondrial haplotypes reflected the extensive gene flow across at a large spatial scale.CONCLUSIONLow‐to‐moderate levels of genetic diversity were observed, and evidence was found for genetic clustering in certain geographical areas. Accordingly, our unique insights into S. exigua population genetics and spatiotemporal migration dynamics help to guide applied ecological studies, ecological intensification schemes or (area‐wide) pest management campaigns in China and abroad. © 2021 Society of Chemical Industry.
Urban labour market and de facto citizenship: Understanding migrant's settlement intention in China
Authors: Yang Sisi , Guo Fei 
Published: October 2021

AbstractThis study examines the changing role of traditional employment sector and the access to employment‐related citizenship rights in affecting migrant workers' settlement intentions in China. Traditionally, migrants who are informally employed were viewed as unsettled groups in Chinese cities. However, the expanded employment‐related citizenship rights provide more diverse channels for pursuing permanent urban settlement. We use data from China Migrants Dynamic Survey in 2013 to investigate migrant workers' permanent settlement intentions, taking into account their access to employment‐related citizenship rights, employment sector,hukoustatus, social‐economic attachments at the places of destination and origin, and regional variations. We found that self‐employed and informally employed migrants held a stronger intention to pursue permanent settlement if they were protected by the local urban insurance schemes, the so‐called “de facto” employment‐related citizenship. The study suggests that the dichotomy of employment sectors, formal versus informal, in understanding migrants' settlement decision has been weakened in China.
Event‐triggered fault detection for discrete‐time Markovian jump systems in finite frequency domain
Authors: Cheng Peng , Cai Chenxiao 
Published: October 2021

AbstractThis paper is concerned with the design of the finite frequency fault detection (FD) filter based on the event‐triggered scheme (ETS) for discrete‐time Markovian jump (DMJ) systems with Lipschitz functions, time‐varying delays, and packet dropouts. A novel FD filter subject to ETS and data missing is developed, and the augmented filter system is rewritten as a DMJ‐linear parameter varying (DMJ‐LPV) system through a reformulated Lipschitz property. Then, two novel lemmas are proposed to guarantee the DMJ‐LPV system robust to unknown disturbances and sensitive to finite frequency faults. Next, the proposed lemmas are deduced into linear matrix inequalities by using Finsler's lemma and S‐procedure. Finally, the application of Chua's circuit system is employed to illustrate the validity and superiority of the proposed theory.
Dialog‐constraining institutional logics and their interactional manifestation in the science classroom
Authors: Zafrani Eran , Yarden Anat 
Published: October 2021

AbstractThis study seeks to understand why dialogic argumentation has not been adopted as a legitimate means of instruction by science teachers. To answer this question, this qualitative case study examines the mutually constitutive relationships between macrolevel phenomena, such as the taken‐for‐granted institutional mandates that teachers and schools call upon to maintain their legitimacy in society, and microlevel routinized teacher–student classroom interactions. Integrating ethnography with the analysis of classroom interactions, we seek to capture the social structuring that informs instruction and classroom interactions. Based on an inductive analysis of observations, interviews with teachers, and documents, three types of macrolevel institutional logics that mediate against the implementation of dialogic argumentation emerged. These included the logics of (a) accountability, (b) tracking, and (c) the profession. These logics give rise to instructional practices that run counter to the pursuit of dialogic argumentation. Classroom observations were analyzed to examine how these logics are conveyed through institutionally bounded interactions between teachers and students. Shaped by these institutional logics, instruction in classrooms is narrowed to mostly direct instruction of terminology and absolute facts, and is stratified into various status levels according to classroom tracking. We argue that teachers may resist dialogic argumentation primarily because it violates the fundamental rules, norms, and practices that grant them individual and organizational legitimacy. This contextualization of teacher–student interactions as motivated by institutional logics may explain in greater detail the absence of dialogic argumentation from science classrooms.

Published: October 2021

AbstractThis study aims to empirically evaluate the effect of low carbonation, crime rate, and logistical infrastructure on tourism and economic development of the Association of Southeast Asian Nations (ASEAN) tourist countries through structural equation modeling for the sample period from 2011 to 2019. The proposed model presented six hypotheses among four constructs that suggest that logistic performance and renewable energy consumption positively affect tourism, whereas the crime rate harms tourism in ASEAN countries. As far as the economic growth of ASEAN countries is concerned, it is positively affected by logistic performance, renewable energy, and tourism. Thus, it can be concluded that better ecological conditions with less carbon emission through the use of renewable energy, efficient logistics services and infrastructure, and a peaceful environment with a low‐crime rate can boost the tourists' arrival, which in turn would be beneficial for the economy of ASEAN countries.
The role of prenatal posttraumatic stress symptoms among trauma exposed women in predicting postpartum depression
Authors: Grekin Rebecca , Thomas Emily B. K. , Miller Michelle L. , O’Hara Michael W. 
Published: October 2021

AbstractResearch suggests that a history of trauma and prenatal posttraumatic stress symptoms (PTSS) are predictive of postpartum depression (PPD). Pregnant women at risk for PPD are often identified through depression symptom measures, while PTSS also may help to identify those at increased risk. Women who do not endorse depressive symptoms, though experience PTSS, may be missed when screening is exclusively based on depressive symptoms. The current study aimed to determine if prenatal PTSS were associated with PPD at 4‐ and 12‐week postpartum in trauma‐exposed women. Pregnant women (N = 230) in their third trimester were assessed for depression and PTSS at pregnancy, 4 and 12 weeks postpartum. Traumatic life events were assessed during pregnancy. Hierarchical regression analyses examined predictors of PPD, including history of depression, number of past traumas, and symptoms from the posttraumatic stress disorder (PTSD) Checklist short‐form (PCL‐6). At 4 and 12 weeks postpartum, history of trauma and depression did not predict depressive symptoms, however, irritability and unwanted intrusive memories of trauma were predictive of increased depressive symptoms. Prenatal irritability and unwanted memories may be predictive of elevated PPD symptoms. Future research should examine whether these symptoms represent increased risk of postpartum depressive symptoms to improve screening, prevention, and treatment efforts.
Demand agglomeration economies, neighbor heterogeneity, and firm survival: The effect of HHGregg's bankruptcy
Authors: Sharma Siddharth , Chung Wilbur 
Published: October 2021

Research SummaryWhile agglomeration economies can enhance collocated firms' performance, firms' gains will be heterogeneous. Gains will be driven not only by firms' own traits, but also by their neighboring firms' traits. We expect a focal firm gains more from neighbors that are larger, more proximate geographically, and more related in economic activity. We leverage a quasi‐experiment that features micro‐geographic, establishment‐level data: the exit of the HHGregg electronics retailer in outdoor shopping malls, to estimate the intensity of demand agglomeration benefits from two sources: (a) a focal‐pair—how HHGregg's exit harms a focal store's survival, and (b) the other neighbors—how the attributes of the remaining neighbors attenuate this reduced survival effect. We find results consistent with the focal store's, HHGregg's, and neighbors' heterogeneity in size and distance affecting the focal store's survival.Managerial SummaryWhile firms can benefit from being located near one another, the benefits vary with both a focal firm's characteristics but also neighboring firms' characteristics. A firm should benefit more from neighbors that are larger, physically closer, and engaged in more similar activity. We examine how the bankruptcy of the HHGregg electronics retailer negatively affected other stores in outdoor shopping malls, and how that loss in benefit was attenuated by the remaining neighbors. We find that a focal store's survival is affected by the focal store's, HHGregg's, and neighbors' heterogeneity in size and physical distance.
Iridium in Tungsten Trioxide Matrix as an Efficient Bi‐Functional Electrocatalyst for Overall Water Splitting in Acidic Media
Authors: Li Pengsong , Duan Xinxuan , Kuang Yun , Sun Xiaoming 
Published: October 2021

AbstractElectrocatalytic water splitting in acidic media is a promising strategy for grid scale production of hydrogen using renewable energy, but challenges still exist in the development of advanced catalysts with both high activity and stability. Herein, it is reported that iridium doped tungsten trioxide (Ir‐doped WO3) with arrayed structure and confined Ir sites is an efficient and durable bi‐functional catalyst for overall acidic water splitting. A low overpotential (258 mV) is required to achieve an oxygen evolution reaction current density of 10 mA cm−2 in 0.5 m H2SO4 solution. Meanwhile, Ir‐doped WO3 processes a similar intrinsic activity to Pt/C toward hydrogen evolution reaction. Overall water splitting using the bi‐functional Ir‐doped WO3 catalyst shows low cell voltages of 1.56 and 1.68 V to drive the current densities of 10 and 100 mA cm−2, respectively, with only 16 mV decay observed after 60 h continuous electrolysis under the current density of 100 mA cm−2. Structural analysis and density functional theory calculation indicate that the adjusted coordination environment of Ir within the crystalline matrix of WO3 contributes to the high activity and durability.

Published: October 2021

AbstractRechargeable silicon anode lithium ion batteries (SLIBs) have attracted tremendous attention because of their merits, including a high theoretical capacity, low working potential, and abundant natural sources. The past decade has witnessed significant developments in terms of extending the lifespan and maintaining high capacities of SLIBs. However, the detrimental issue of low initial Coulombic efficiency (ICE) toward SLIBs is causing more and more attention in recent years because ICE value is a core index in full battery design that profoundly determines the utilization of active materials and the weight of an assembled battery. Herein, a comprehensive review is presented of recent advances in solutions for improving ICE of SLIBs. From design perspectives, the strategies for boosting ICE of silicon anodes are systematically categorized into several aspects covering structure regulation, prelithiation, interfacial design, binder design, and electrolyte additives. The merits and challenges of various approaches are highlighted and discussed in detail, which provides valuable insights into the rational design and development of state‐of‐the‐art techniques to deal with the deteriorative issue of low ICE of SLIBs. Furthermore, conclusions and future promising research prospects for lifting ICE of SLIBs are proposed at the end of the review.

Published: October 2021

AbstractWater‐infiltration‐induced power generation has the renewable characteristic of generating electrical energy from ambient water. Importantly, it is found that the carrier concentration in semiconductor constituting the energy generator seriously affect the electricity generation. Nevertheless, few studies are conducted on the influence of semiconductor carrier concentration, a crucial factor on electricity generation. Due to this, understanding of the energy harvesting mechanism is still insufficient. Herein, the semiconductor carrier concentration‐dependent behavior in water‐infiltration‐induced electricity generation and the energy harvesting mechanism by ionovoltaic effect are comprehensively verified. A clue to enhance the electric power generation efficiency is also proposed. When 20 µL of water (NaCl, 0.1 m) infiltrates into a porous CuO nanowires film (PCNF), electric power of ≈0.5 V and ≈1 µA are produced for 25 min. Moreover, the PCNF shows good practicability by generating electricity using various ambient water, turning on LEDs, and being fabricated as a curved one.

Published: October 2021

AbstractArming metasurface with active materials furnishes a feasible solution to dynamically control over terahertz (THz) waves, which is extremely significant for the realization of upcoming sixth generation telecommunications. However, the present active materials are mainly limited to single external driving field, hindering the capability of metasurface for flexible manipulation of THz waves. Besides, less attention has been paid to the energy question how to significantly reduce the pump threshold for achieving the desired function. Here, a germanium (Ge) hybrid Fano metasurface under dual‐stimulus control is experimentally demonstrated. Photoexcitation of Ge thin film enables 100% modulation depth of Fano resonance and ultrafast switching time within 10 ps. By adding current‐bias, the pump threshold to modulate the metasurface is greatly reduced from 1600 to 200 µJ cm−2. Different from the optical modulation independent of film thickness, it is found that the current function is in proportion with the thickness of Ge thin film. Moreover, it is demonstrated that compared to the single optical‐stimulus, the THz amplitude modulation is increased by 56.3% under dual‐stimulus function. This work naturally improves the flexibility and practicality of Ge‐based metadevice and inspires more innovations to boost the development of switchable sensing, lasing spacer, and nonlinear systems.

Published: October 2021

AbstractAn unusual tree was collected in the Manu National Park in Peru in 1973 and although recollected many times, remained unidentified for decades. Preliminary molecular analysis indicated that it belonged to the Picramniaceae, even though the vegetative features were discordant. Using the nuclear marker ITS and the chloroplast marker rbcL, sequences were analyzed using Bayesian inference and maximum likelihood methods. The molecular analyses and study of the morphology showed that it is a new genus and species of Picramniaceae, herein described as Aenigmanu alvareziae. We provide a full morphological description, illustrations, and a distribution map of the new taxon, as well as a revised key to the genera of Picramniaceae.
