How, when, and why high job performance is not always good: A three‐way interaction model
Authors: Peng Yan , Cheng Bao , Tian Jian , Zhang Zhenduo , Zhou Xing , Zhou Kun 
Published: August 2023

SummaryDespite organizations encouraging employees to improve their job performance to enhance organizational performance, the understanding of the consequences of high performance from the perspective of social comparison remains limited. Drawing on social comparison theory, we develop a framework explaining how upward performance social comparison leads to political behaviors through anxiety. Furthermore, we examine the amplifying effect of social comparison orientation (SCO) on the relationship between upward performance social comparison and anxiety. We introduce the downward leader–member exchange social comparison (downward leader–member exchange social comparison [LMXSC]) to buffer the magnifying effect of SCO. We test the three‐way interaction among upward performance social comparison, SCO, and downward LMXSC using the data collected from a three‐wave survey (Study 1) and a scenario‐based experiment (Study 2), and our hypotheses are supported. Our results reveal an interesting dilemma. Employees' high performance is naturally beneficial for organizations, but those with high SCO and fewer advantages in leader–member exchange social comparison may feel more anxious and engage in political behaviors in response to upward performance social comparison. Our research has practical implications, such as monitoring social comparisons and political behaviors in the workplace and helping employees reduce anxiety.
Thermally activated persulfate oxidation of Basic Fuchsin dye: Effect of different operating parameters, kinetic, and thermodynamic study
Authors: Habache Naima , Bechiri Ouahiba 
Published: August 2023

AbstractThe present paper aims to investigate the efficiency of thermal activation persulfate in eliminating the organic dye “Basic Fuchsin” (BF). In addition, the study attempts to elucidate the effect of different operating parameters, such as persulfate dosage (0.44–4.4 mM), the initial solution pH of (3–10), and temperature (25–50°C), on the process. The effects of various anions and water matrices on BF discoloration were investigated. Thus, the findings revealed that 94.15% of BF can be eliminated using persulfate at a concentration of 4.4 mM and a temperature equal to 50°C. It occurs under the following operating conditions: oxidation time of 60 min, initial pH equal to 6, the pollutant concentration of 10 ppm, and stirring speed equal to 300 rpm. Furthermore, the kinetic study indicated that the degradation of the BF dye using PS followed a first‐order pattern with rate constants varying within a range of 15.3 × 10−3–43.2 × 10−3 min−1. Based on the Arrhenius equation, the activation energy of the studied process was determined to be 29 kJ mol−1, suggesting that a moderate activation energy is required for BF discoloration. The results of the thermodynamic study confirm that the oxidation process is non‐spontaneous and endothermic. Coexisting inorganic anions delayed BF discoloration to varying degrees, and the inhibitory action followed the following order: carbonate > chloride > sulfate > nitrate. Organic pollutants oxidation by the thermal activation of the persulfate is a simple and effective method for the depollution of waste textile water.

AbstractIn the Loess Plateau, gaining insights into the water storage and soil retention functions of diverse vegetation types, especially, in the semi‐arid watersheds is crucial for identifying the key factors necessary to ensure sustainable development and achieve land degradation neutrality. In this study, five different land use types such as forest, shrub, artificial grass, and natural grasslands were surveyed from 2014 to 2020. Meanwhile, bare land was also used as a control plot. The trade‐off between erosion mitigation and water consumption indicator was quantified based on the ecosystem services perspective benefits. Our results showed that there are significant differences among different land use types (p < 0.05): natural grassland > shrubs > artificial grassland > forests. Vegetation restoration was able to change the soil particle size distribution, increasing clay and silt content, and decreasing sand particles. During the growing season, surface soil water storage decreased in all land use types coinciding with the higher decrease in the control plot. The change in surface water storage in the forest was the most stable, with a decrease of 0.13 mm. The trade‐off between erosion mitigation and water consumption indicator was less than 0 for all vegetation types, which indicates a synergistic effect on soil conservation and water storage benefit. Our results demonstrated that shrubs can register the most balanced benefit of water storage and soil preservation. This is a solid basis for the selection of specific vegetation types and the optimization of the watershed landscape in the middle reaches of the Yellow River, characterized by vulnerable areas due to aridification.

Published: August 2023

AbstractObjectiveTo find an adequate cut‐off point for beta trace protein (β‐TP) in nasal secretion (NS) and validate this diagnostic test with a large sample of patients. Likewise, we evaluated β‐TP test efficacy to confirm the cerebrospinal fluid (CSF) leakage closure after treatment.MethodsWe performed a retrospective analysis with 207 samples from 162 patients with suspected CSF leakage received in the Hospital Universitario Virgen de la Arrixaca between 2010 and 2016. Twenty‐five samples were included in the control group. Samples were obtained from NS through a swab to determine β‐TP using a nephelometry‐based assay. Sensitivity, specificity, and area under the curve (AUC) for β‐TP in NS were assessed using the receiver operator characteristic (ROC) analysis.ResultsUsing imaging techniques, the diagnosis of CSF leak was confirmed in 57 patients (35.19%), while 105 had a negative diagnosis (64.81%). Patients with CSF leakage had significantly higher β‐TP values in NS (16.07 ± 16.94 mg/L, p < .001) than the control group (0.33 ± 0.12 mg/L) and patients without CSF leakage (0.61 ± 2.34 mg/L). Applying a 1 mg/L cut‐off point resulted in 96.5% sensitivity and 97.1% specificity. Positive and negative predictive values (PPV and NPV) at this cut‐off were 94.9% and 98.6%, respectively. Finally, this cut‐off point yields a test efficacy for CSF leak diagnosis of 97% (95% CI 92.9–98.9).ConclusionOur study has established a 1 mg/L β‐TP concentration in NS as a cut‐off point for CSF leakage diagnosis with high sensibility and specificity. These results suggest that β‐TP analysis could be useful to check CSF leak resolution.Level of Evidence4.

Authors: Tan Li‐Juan , Hwang Su Bin , Shin Sangah 
Published: August 2023

ScopeUltra‐processing food (UPF) has been a nutrition and health interest. This study is aimed to investigate the association between UPF consumption and the risk of obesity or dyslipidemia.Methods and resultsThis study is performed using an ongoing cohort study including 17 310 individuals aged ≥40 years in South Korea. UPF is categorized by the NOVA system and FCS, respectively. After an average 5‐year follow‐up, there is a positive association between NOVA‐defined UPF and dyslipidemia. The risk of the Q4 group is almost 20% higher than that of the Q1 group (men, adjusted HR = 1.209 [95% CI 1.039–1.407], women, adjusted HR = 1.195 [95% CI 1.096–1.303]). Consuming high‐FCS foods (less processed and healthier foods) show a lower risk for dyslipidemia in both sexes and lower obesity risk in women compared to low‐FCS consumption (men, dyslipidemia, adjusted HR = 0.857 [95% CI 0.744–0.988]; women, dyslipidemia, adjusted HR = 0.919 [95% CI 0.850–0.993], obesity, adjusted HR = 0.759 [95% CI 0.628–0.916]).ConclusionHigher UPF intakes assessed by the NOVA system and FCS are associated with increased incidences of dyslipidemia and obesity. Furthermore, NOVA‐defined UPF shows a statistically significant negative association with AMED score, indicating poor diet quality.

Published: August 2023

AbstractObjectiveLong pentraxin‐3 (PTX‐3) is an acute phase protein associated with cardiovascular disease, lung injury, and mortality. We evaluated the association between computed tomography (CT)‐measurements of adipose tissue and plasma levels of PTX‐3.MethodsWe performed a cross‐sectional analysis of community‐dwelling adults enrolled in the multi‐center Multiethnic Study of Atherosclerosis who underwent cardiac or abdominal CT and had available PTX‐3 measurements.ResultsThere was a U‐shaped association between pericardial adipose tissue volume (PAT), abdominal visceral adipose tissue area (VAT), hepatic attenuation, and PTX‐3 levels, with extremes of adiposity associated with greater PTX‐3 levels. Using multivariable‐adjusted piecewise regression models, among participants with low PAT, every 1% increase in PAT volume was associated with a 13.8% decrease in PTX‐3 (95% confidence interval [CI] −21.6 to −6.0); among participants with high PAT, every 1% increase in PAT volume was associated with a 6.0% increase in PTX‐3 (95% CI −0.4 to 12.5). Results were similar for abdominal VAT and hepatic attenuation.ConclusionsIn a cohort of community‐dwelling adults, we demonstrated a “U‐shaped” association between pericardial, abdominal visceral, and hepatic adiposity with PTX3 levels, suggesting that extreme adiposity is associated with greater circulating levels of PTX3. Further work is required to identify the mechanisms linking adiposity and PTX‐3.

Abstract

Facing the dual threats of climate and socioeconomic changes, how Tibet can seize the opportunity for ecological restoration to enhance environmental quality while improving the relationship between humans and nature is of great significance for regional sustainable development.

Situated in an ecologically vulnerable area, the cognitive structure of Tibetan residents regarding resources and policies is a crucial reference for evaluating whether environmental governance is sustainable. We aimed to detect what impact ecological restoration in Tibet had on the cognitive structures of stakeholders.

We distributed questionnaires to Tibetan residents, distinguished experimental groups (EG, n = 325) and control groups (CG, n = 165) by the implementation of ecological restoration projects or not, used a network approach to construct indicators of overall connectivity and evenness for assessing the cognitive structure and explored the influencing factors on cognitive structures. We found that interviewees in areas where ecological restoration was implemented had more positive perceptions of the importance of ecosystem services, the relationship between ecological conservation and well‐being, attitudes towards ecological restoration, and the impact of governance measures. The overall connectivity and evenness of the EG were significantly higher than those of the CG. It showed an increase in positive stakeholder perceptions about policy and nature and a greater emphasis on the balance between environmental protection and productive life. The implementation of ecological restoration enhanced the connection between local people and the environment. Elevation and annual precipitation were the geographic influencing factors that dominated overall connectivity.

Based on the cognitive structure of Tibetan residents, the implementation of ecological restoration enhanced connections in social‐ecological systems elements, played a positive role in the human–nature relationship and promoted collective governance of common pool resources. Safeguarding and improving residents' livelihoods and enhancing the regional low‐connectivity cognitive structure under different geographical contexts are important for future governance.

Ultra‐high power density in poly(arylene ether nitrile)‐based composites containing barium titanate and boron nitride nanosheets
Authors: Pu Linyu , Zeng Jingjing , Long Yiting , Zhang Huan , Huang Xu , Liu Jingsong 
Published: August 2023

AbstractBarium titanate (BT) nanoparticles were surface coated by a silane coupling agent (KH550) and core–shell structured nanoparticles (named KH550@BT) were obtained. Similarly, BT nanoparticles coated by polydopamine (PDA) were named as PDA@BT. Meanwhile, boron nitride (BN) nanosheets (BNNS) were successfully unstripped from block BN. Then, two kinds of ternary poly(arylene ether nitrile) (PEN)‐based composites are prepared using the solution casting method. Composites with 30 wt% KH550@BT and 12 wt% BNNS were named as KH550@BT/BNNS/PEN. Composites with 30 wt% PDA@BT and 12 wt% BNNS were named as PDA@BT/BNNS/PEN. The microstructure, dielectric properties, and energy storage properties of the ternary composites were studied in detail. PEN embedded with either BNNS or BT were prepared and studied for comparison. As a result, the introduction of BT will improve the dielectric constant (εr) and energy storage density (W), but it will reduce the breakdown strength (Eb) and charge–discharge efficiency (η) of composites. BNNS not only improves Eb and W but also improves η of composites. Although the introduction of BT and BNNS simultaneously may reduce η, it will improve εr, Eb, and W of composites. Most importantly, the fast discharge speed and high power density demonstrate that the BT/BNNS/PEN composites are potential candidates to be used in high power pulsed capacitors fields.Highlights
Boron nitride nanosheets improve the breakdown strength of composites.
The composites achieve simultaneous increment of εr and Eb.
The power density of the BT/BNNS/PEN composites was higher than 70 MW cm−3.
Pull‐out behavior of polymer fibers in concrete

Published: August 2023

AbstractThe bond between polymer fibers and the surrounding cementitious matrix is essential for the development of concrete reinforcement. The single fiber pull‐out test (SFPT) is the standard characterization technique for testing the bond strength. However, the different phases of debonding cannot be distinguished by the SFPT. This study investigates the debonding of different polymer fibers from the surrounding cementitious matrix with a modified SFPT and proposes methods to change the SFPT setup to generate more valuable information on the debonding mechanism. The SFPT was equipped with linear variable differential transformers (LVDT), digital image correlation (DIC) and acoustic emission (AE) analysis. The results demonstrate that the modified SFPT allows a better understanding of the different phases of debonding during fiber pull‐out. Furthermore, bond strength values calculated by different methods reveal that the chemical bond of the investigated polymers is not different as reported by previous studies. Deformation measurements performed using LVDTs and DIC are suitable measuring techniques to characterize the debonding mechanism in SFPT. A correlation between recorded AE and debonding phases was not found.

AbstractObjectiveCancer patients parenting minor children face specific burden and supportive needs, which are often not adequately addressed by their healthcare professionals (HCPs), due to a lack of knowledge, self‐efficacy and competencies. Therefore, we developed a 3‐h intervention enhancing HCPs' competencies in caring for these patients. We pilot‐evaluated the intervention's feasibility and efficacy, assuming intervention group participants reveal higher improvements over time compared to non‐trained participants.MethodsWe conducted a 3‐armed randomized controlled pilot‐trial (RCT), comparing face‐to‐face training (F2F), e‐Learning (EL), waitlist‐control group with three measurements (baseline, post‐training, 3‐month follow‐up). Primary outcome was the competency to approach child‐ and family‐related themes; secondary outcomes were knowledge, self‐efficacy in (specific) communication skills. Intervention effects were analyzed using linear mixed models.ResultsParticipants (n = 152) were mostly female (89%) and psychologists (38%; physicians 26%; nurses 18%). F2F and EL participants reported high training satisfaction. Analyses did not reveal any significant differences on the primary outcome between groups, but indicate positive intervention effects over time regarding secondary outcomes including knowledge and self‐efficacy in communication skills.ConclusionsThis is the first pilot‐study evaluating a training for HCPs in oncology on parental cancer using a 3‐armed RCT. The 3‐h training program is a feasible approach and findings indicate to increase HCPs' knowledge and self‐efficacy in caring for cancer patients with minor children. Further research is needed to verify preliminary findings of this pilot study. The study was pre‐registered within the German Clinical Trial Register (DRKS‐00015794).
Maximum approximate likelihood estimation in accelerated failure time model for interval‐censored data
Authors: Guan Zhong 
Published: August 2023

AbstractThe approximate Bernstein polynomial model, a mixture of beta distributions, is applied to obtain maximum likelihood estimates of the regression coefficients, the baseline density and the survival functions in an accelerated failure time model based on interval censored data including current status data. The estimators of the regression coefficients and the underlying baseline density function are shown to be consistent with almost parametric rates of convergence under some conditions for uncensored and/or interval censored data. Simulation shows that the proposed method is better than its competitors. The proposed method is illustrated by fitting the Breast Cosmetic and the HIV infection time data using the accelerated failure time model.
Direct Observation of Vacancy‐Cluster‐Mediated Hydride Nucleation and the Anomalous Precipitation Memory Effect in Zirconium

Published: August 2023

AbstractControlling the heterogeneous nucleation of new phases is of importance in tuning the microstructures and properties of materials. However, the role of vacancy—a popular defect in materials that is hard to be resolved under conventional electron microscopy—in the heterogeneous phase nucleation remains intriguing. Here, this work captures direct in situ experimental evidences that vacancy clusters promote the heterogeneous hydride nucleation and cause the anomalous precipitation memory effect in zirconium. Both interstitial and vacancy dislocation loops form after hydride dissolution. Interestingly, hydride reprecipitation only occurs on those vacancy loop decorated sites during cooling. Atomistic simulations reveal that hydrogen atoms are preferentially segregated at individual vacancy and vacancy clusters, which assist hydride nucleation, and stimulate the unusual memory effect during hydride reprecipitation. The finding breaks the traditional view on the sequence of heterogeneous nucleation sites and sheds light on the solid phase transformation related to vacancy‐sensitive alloying elements.

AbstractStem‐cell‐based therapeutics have shown immense potential in treating various diseases that are currently incurable. In particular, partial recovery of Parkinson's disease, which occurs due to massive loss or abnormal functionality of dopaminergic (DAnergic) neurons, through the engraftment of stem‐cell‐derived neurons ex vivo is reported. However, precise assessment of the functionality and maturity of DAnergic neurons is still challenging for their enhanced clinical efficacy. Here, a novel conductive cell cultivation platform, a graphene oxide (GO)‐incorporated metallic polymer nanopillar array (GOMPON), that can electrochemically detect dopamine (DA) exocytosis from living DAnergic neurons, is reported. In the cell‐free configuration, the linear range is 0.5–100 µm, with a limit of detection of 33.4 nm. Owing to its excellent biocompatibility, a model DAnergic neuron (SH‐SY5Y cell) can be cultivated and differentiated on the platform while their DA release can be quantitatively measured in a real‐time and nondestructive manner. Finally, it is showed that the functionality of the DAnergic neurons derived from stem cells can be precisely assessed via electrochemical detection of their DA exocytosis. The developed GOMPON is highly promising for a wide range of applications, including real‐time monitoring of stem cell differentiation into neuronal lineages, evaluating differentiation protocols, and finding practical stem cell therapies.
