The impact of work hours on work‐to‐family enrichment and conflict through energy processes: A meta‐analysis
Authors: Pak Sunjin , Kramer Amit , Lee Yin , Kim Ki‐Jung 
Published: December 2021

SummaryWe use a meta‐analysis to introduce a framework that integrates research on the relationship between working hours and the work–family interface. Using the work–home resources model, we integrate work–family enrichment and conflict theory, focusing on the positive and negative mediational processes of human energy. We conceptualize working hours, within the framework of the work–home resources model, as the potential to increase vigor and exhaustion in tandem, which, in turn, would lead to increased work–family enrichment and work–family conflict, respectively. Our model suggests, and a meta‐analytic investigation (N = 459 846), supports that the two dimensions of human energy, vigor and exhaustion, mediate the relationship between working hours and work‐to‐family enrichment and conflict, respectively. Taken together, our findings contribute to the literature by integrating the positive and negative energy mechanisms in the relationship between working hours and work‐to‐family enrichment and conflict. Specifically, by showing the parallel paths of vigor and exhaustion that occur when individuals increase working hours, we reconcile mixed findings regarding the effect of working hours on the work–family interface.

AbstractBACKGROUNDPolymethoxylated flavones (PMFs) show multiple biological functions, while their high hydrophobicity leads to a low bioaccessibility and limits their wide applications. The design of a reasonable food‐grade drug delivery system is an effective strategy to improve the low bioaccessibility of PMFs. In this study, sinensetin, tangeretin and nobiletin were encapsulated in Pickering emulsions stabilized by zein/pullulan complex colloidal particles (ZPPs), and the protection effect and in vitro digestion were characterized.RESULTSRheological analysis revealed that ZPP–Pickering emulsion loading with PMFs maintained a strong gel‐like network structure. Moreover, the ability to scavenge free radicals of PMFs was improved by the emulsion delivery system. The antioxidant activity of PMFs encapsulated in Pickering emulsion was positively correlated with the oil volume fraction (φ). ZPP–Pickering emulsion loading with PMFs can effectively delay lipid oxidation, and the φ (70%) of Pickering emulsion showed the most pronounced effects, in which the lipid hydroperoxide content and malondialdehyde content decreased by 64.3% and 38.3% after 15 days of storage, compared with the bulk oil group, respectively. The bioaccessibility of the three PMFs has been increased by ZPP–Pickering emulsion simultaneously and it presented the highest values as its φ was 50%, in which the bioaccessibility of sinensetin, tangeretin and nobiletin increased by 2.5, 3.2 and 3.9 times, compared with the bulk oil group, respectively.CONCLUSIONPickering emulsion stabilized by ZPPs is an excellent nutrient delivery system for delivering three PMFs simultaneously and imparting functional properties to bioactive delivery systems. © 2022 Society of Chemical Industry.

AbstractA new green miniaturized quick, easy, cheap, effective, rugged, and safe approach was developed and used for the extraction of multiclass 16 pesticides in milk before gas chromatography analysis. The miniaturization of method reduced the consumption of chemical reagents and samples. Magnetic three‐dimensional graphene was used as sorbent in the clean‐up step. Choline chloride:lactic acid (1:2) natural deep eutectic solvent was used as desorption solvent. Temperature‐assisted solidification of floating menthol drop was executed for preconcentration of analytes. The method parameters including sorbent, desorption solvent, sorption and desorption times, menthol amount, pH, and ionic strength were optimized. The limit of quantification and linear range were 0.03–0.38 and 0.03–250 μg/kg, respectively. The accuracy was assessed by recovery evaluation at the spike levels of 50 and 100 μg/kg, in the range of 61–119%, with relative standard deviations within 2.1–18.2%. The method was applied to the analysis of pasteurized low and high‐fat bovine milk, and various pesticide residues were detected in the concentrations range of 1.24–4.68 μg/kg. Finally, the greenness of the procedure was evaluated using the Analytical Eco‐Scale. This work represents the first application of hybrid miniaturized extraction/preconcentration using a natural deep eutectic solvent and menthol to analyze pesticides.

AbstractSoil microbes greatly contribute to the regulating of phosphorus (P) cycling, which plays a significant role in maintaining wetland ecosystem processes and function. The microbial functional diversity of soil P cycling in response to wetland degradation, however, remains largely unknown. We used metagenomic sequencing to investigate the microbial community and genes related to soil P cycling in un‐degraded marshes and meadows derived from long‐term marsh degradation in the Lalu alpine wetland of the Tibetan Plateau. When the marsh degraded into meadow, organic P (OP) mineralization genes increased while genes related to P‐starvation response regulation decreased. Proteobacteria (20.5–74.3%) and Actinobacteria (5.6–59.7%) were the dominant phyla in soils and were also the main contributors (39.7–84.1% in total) to soil P‐cycling genes. Soil pH was the primary factor influencing the P‐cycling functional genes. Soil pH negatively affected the genes related to the P‐uptake and transport system and had negative effects on the genes related to P‐starvation response regulation, OP mineralization, and inorganic P solubilization. These findings may deepen our understanding of the biogeochemical process of soil OP and may be beneficial for wetland management.

Published: December 2021

AbstractSince 1997, dense blooms of the alga Phaeocystis globosa have occurred in the South China Sea (SCS), and previous studies have revealed the co‐existence in this sea of two types of P. globosa cell characterized by different marker pigment profiles. However, owing to a lack of quantitative methods for the detection of different types of P. globosa cells, the dynamics of P. globosa blooms in the SCS are still poorly understood. In this study, on the basis of phylogenetic analysis of the mitochondrial atp8 (Mit atp8) gene and pigment profiles, the P. globosa strains from Pacific and Atlantic coastal waters were divided into four genotypes, of which Type I and Type IV strains co‐exist in the SCS. Furthermore, two genotype‐specific quantitative polymerase chain reaction (qPCR) methods were developed targeting the Mit atp8 gene for quantitative determinations of the densities of Type I and Type IV P. globosa cells. Both qPCR methods were reproducible, highly sensitive, and specific with a wide range of detection (from 30 to 1 × 108 cells L−1) for target P. globosa genotypes in the field, thereby facilitating the detection of low cell densities prior to bloom development, as well as high cell densities during bloom periods. Finally, the developed qPCR assays were successfully applied to determine the distribution patterns of Type I and Type IV P. globosa in the Beibu Gulf, a region of the SCS characterized by a high frequency of P. globosa blooms.

AbstractThis work aims to study the influences of 1‐ethyl‐3‐methylimidazolium acetate, [EMIm]Ac ionic liquid incorporation with various weight percentage to the characteristics of biopolymer blend electrolytes (BBEs) based on methyl cellulose/carboxymethyl cellulose (MC/CMC) (50/50) blend, i.e., the ionic conductivities, crystallinities, mechanical properties, surface morphology, and thermal stability. [EMIm]Ac ionic liquid is synthesized using a metathesis reaction between [EMIm]Br and CH3COOK in methanol solvent, while the BBEs preparation is conducted using casting solution technique. The functional groups and molecular structure of BBEs samples are confirmed by using Fourier transform infra red (FTIR) and nuclear magnetic resonce (NMR), while the characteristics of ionic conductivities, mechanical properties, crystallinities, surface morphology, and stability thermal are conducted using electrochemical impedance spectroscopy, tensile tester, X‐ray diffraction (XRD), scanning electron microscopy, and thermogravimetry analysis/differential thermogravimetry (TGA/DTG). The [EMIm]Ac ionic liquid incorporation greatly affects the characteristics of BBEs with optimum condition at the 15% [EMIm]Ac ionic liquid incorporation with a value of 1.53 × 10−2 S cm−1, 20.83 MPa/21.57%, and 217.24–356.34 ℃ for ionic conductivity, tensile strength/elongation at break, and decomposition temperature, respectively. The optimum condition from this study fulfills the standard minimum requirement for a lithium‐ion battery separator.

Authors: Qian Chengbin , Huang Peng , Zhu LiMin , Zhu Zhiwei 
Published: December 2021

AbstractThis paper reports a facile and high‐throughput method for the controllable fabrication of polymeric miniature lens arrays. Through filling the miniature holes in an additively manufactured template, the curved lenslets are formed in each hole in s steady state, in which the gravity and surface tension of the liquid resin are balanced. Both shapes and curvatures can be controlled by tuning the gravity force and the boundary condition for the resin in each hole. Taking the circular holes for example, the relationship between the formed curvature and the gravity force is described by both analytical and finite element‐based numerical models. Experimentally, the curvature variation and the effect of various boundary conditions on the lenslet surface shapes are also verified, and further examination on the optical features of the spherical miniature lens arrays including the imaging and focus properties demonstrates the effectiveness of the developed fabrication method.

Published: December 2021

AbstractThe existence of micro‐structures endows the materials with some novel characteristics. In this study, the hot‐spot material thermoplastic polyurethane (TPU) is used as the experimental object, and the water‐lubricating composites are prepared by introducing well‐hydrophilic polyvinyl alcohol (PVA) fibers, which can spontaneously and continuously produce micro‐convex textures in water. By observing and analyzing the internal structures, physical and chemical properties, coefficient of friction, wear surface, wear loss, etc. of the materials, the relationship between the micro‐convex structures on the material surface and its tribological properties is studied. The experimental results show that the existence of micro‐convex structures can make the material show better wear resistance during the friction process, and they will not disappear completely with the process. The most obvious effect is the sample containing 15% PVA fibers and with soaking and polishing treatments, its coefficient of friction is 0.11, which is 74.42% lower than that of the pure sample without any treatments, the main reason is due to the hydrodynamic lubrication effect and cavitation effect of the micro‐convex structures. For the wear mechanism, pure samples are adhesive wear, and modified samples are mainly abrasive wear. This work will provide new design ideas for tribology in the micro‐nano field.

AbstractBackgroundCHILD syndrome is an X‐linked dominant disorder associated with pathogenic mutations in the NSDHL gene. The condition is predominantly found in females as it is lethal in males. Most cases present at birth with extensive unilateral ichthyosiform erythroderma involving the trunk and limbs. Milder and less extensive presentations have been reported, leading to misdiagnosis especially during early childhood.Methods and ResultsWe report an adult female of Malay ancestry who presented with minimal skin and limb involvement. She was only diagnosed in adulthood when she presented with gastrointestinal symptoms and worsening of skin manifestations. The clinical diagnosis was suspected after a combination of clinical, pathological and immunohistochemistry correlation, and molecularly confirmed with the discovery of a frameshift variant in NSDHL. The novel variant was inherited from her mother who had some linear hypopigmented patches over the medial aspects of both her arms and right forearm.ConclusionWe uncovered a novel frameshift variant associated with presentations that cast a new light on the clinical features of CHILD syndrome.

AbstractPurposeTo evaluate the safety of MRI in patients with fragmented retained leads (FRLs) through numerical simulation and phantom experiments.MethodsElectromagnetic and thermal simulations were performed to determine the worst‐case RF heating of 10 patient‐derived FRL models during MRI at 1.5 T and 3 T and at imaging landmarks corresponding to head, chest, and abdomen. RF heating measurements were performed in phantoms implanted with reconstructed FRL models that produced highest heating in numerical simulations. The potential for unintended tissue stimulation was assessed through a conservative estimation of the electric field induced in the tissue due to gradient‐induced voltages developed along the length of FRLs.ResultsIn simulations under conservative approach, RF exposure at B1+ ≤ 2 µT generated cumulative equivalent minutes (CEM)43 < 40 at all imaging landmarks at both 1.5 T and 3 T, indicating no thermal damage for acquisition times (TAs) < 10 min. In experiments, the maximum temperature rise when FRLs were positioned at the location of maximum electric field exposure was measured to be 2.4°C at 3 T and 2.1°C at 1.5 T. Electric fields induced in the tissue due to gradient‐induced voltages remained below the threshold for cardiac tissue stimulation in all cases.ConclusionsSimulation and experimental results indicate that patients with FRLs can be scanned safely at both 1.5 T and 3 T with most clinical pulse sequences.

Published: December 2021

Noninvasive methods to study changes in tumor microstructure enable early assessment of treatment response and thus facilitate personalized treatment. The aim of this study was to evaluate the diffusion MRI model, Vascular, Extracellular and Restricted Diffusion for Cytometry in Tumors (VERDICT), for early response assessment to external radiation treatment and to compare the results with those of more studied sets of parameters derived from diffusion‐weighted MRI data. Mice xenografted with human small intestine tumors were treated with external radiation treatment, and diffusion MRI experiments were performed on the day before and up to 2 weeks after treatment. The diffusion models VERDICT, ADC, IVIM, and DKI were fitted to MRI data, and the treatment response of each tumor was calculated based on pretreatment tumor growth and post‐treatment tumor volume regression. Linear regression and correlation analysis were used to evaluate each model and their respective parameters for explaining the treatment response. VERDICT analysis showed significant changes from day −1 to day 3 for the intracellular and extracellular volume fraction, as well as the cell radius index (p < 0.05; Wilcoxon signed‐rank test). The strongest correlation between the diffusion model parameters and the tumor treatment response was seen for the ADC, kurtosis‐corrected diffusion coefficient, and intracellular volume fraction on day 3 (τ = 0.47, 0.52, and −0.49, respectively, p < 0.05; Kendall rank correlation coefficient). Of all the tested models, VERDICT held the strongest explanatory value for the tumor treatment response on day 3 (R2 = 0.75, p < 0.01; linear regression). In conclusion, VERDICT has potential for early assessment of external radiation treatment and may provide further insights into the underlying biological effects of radiation on tumor tissue. In addition, the results suggest that the time window for assessment of treatment response using dMRI may be narrow.
Long‐horizon finite‐set model predictive control for grid‐connected photovoltaic inverters

Published: December 2021

AbstractThis article addresses the grid‐connected single‐phase photovoltaic (PV) inverter control. A long‐horizon finite‐set model predictive control (MPC) strategy is proposed to control the voltage source inverter. To achieve this, a multi‐step implementation approach and a control sequence rearrangement method are designed to reduce the sampling frequency and switching frequency. The optimization problem for the finite‐set MPC is further simplified to reduce the computational complexity of the optimization procedure. Moreover, a multi‐step delay compensation method is developed to compensate for the computational delay of the control algorithm. Finally, the proposed control method is implemented in a grid‐connected PV inverter and simulation test results demonstrate its effectiveness under different load and generation conditions.
Unpacking government social media messaging strategies during the COVID‐19 pandemic in China

Published: December 2021

AbstractA core aspect of agile governance is effectively managing communications between a government and its citizens. However, doing so during an emergency—particularly a pandemic—is often complex and challenging. In this article, we examine how various levels of the Chinese government (central, provincial, and municipal) communicated with the public in response to the COVID‐19 pandemic. Analyzing government social media posts during the COVID‐19 outbreak in Wuhan (“text as data”), we conduct topic modeling analysis and identify four strategies that characterize Chinese governments’ responses to a variety of issues at the ground level, which we labelinstructing information, adjusting information, advocacy, andbolstering. The results show that local government agencies predominantly used the first two strategies, whereas the central government mainly relied on the last two. These strategies explain how various levels of government engaged in agile governance through their communication with citizens, highlight the coordination and control work undertaken by governments at all levels, and demonstrate how these methods shielded the central government from blame for the pandemic.
An amphiphilic polymer for the synthesis of diverse polymer libraries exemplified using conjugates with lower critical solution temperatures that span water's liquid state

Published: December 2021

AbstractThe discovery of new polymer functions is intrinsically tied to the synthesis of diverse structures. Herein we report the synthesis of a new polymer library precursor, poly[N‐(12‐carboxyl‐3,6,9‐trioxado) methacrylamide] (pCTMAAm), that is functionalizable with hydrophilic or hydrophobic ligands in both protic and aprotic solvents. The polymer is made through RAFT polymerization with narrow dispersities. Carboxylic acid groups terminate the pCTMAAm side chains, which allows conjugation of both hydrophobic and hydrophilic groups. As a demonstration, three very different ligands, agmantine (cation), galactosamine (polyol) and hexylamine (hydrophobic), were conjugated to pCTMAAm using DMTTM as a condensing agent with greater than 80% conjugation efficiency. To demonstrate the potential utility of the amphiphilic polymer, a polymer library containing side chains with a series of alkanes and varying degrees of substitution was synthesized showing lower critical solution temperature (LCST) profiles that span a temperature range of 7 °C to above 90 °C in water. Multivariate linear regression analysis of the polymer library was used to understand how polymer composition correlates to LCST, using molecular weight, alkane length and degree of substitution as continuous variables. The outcome showed that alkane length has the greatest influence on LCST and that LCST can be estimated using these material composition inputs.
Hydrogel‐shelled biodegradable microspheres for sustained release of encapsulants
Authors: Oh Yoonjin , Kim Shin‐Hyun 
Published: December 2021

AbstractBiodegradable microparticles are promising for the sustained release of encapsulated lipophilic drugs. In particular, the microparticles with uniform size show excellent linearity of cumulated release over time with minimized initial burst. Here, we encapsulate the biodegradable microparticles with a hydrogel shell to improve the controllability over the sustained release and suspension stability. With a capillary microfluidic device, monodisperse oil‐in‐water‐in‐oil (O/W/O) double‐emulsion droplets are produced to have a toluene solution of polylactic acid (PLA) in the core and sodium alginate and calcium‐ethylenediaminetetraacetic acid (EDTA) complex in the shell, whereas the continuous oil phase contains acetic acid. As the toluene evaporates, PLA consolidates to form a microsphere in the core. At the same time, acetic acid diffuses from the continuous phase to the water layer, which causes the dissociation of the Ca‐EDTA complex and the gelation of alginate. The hydrogel‐shelled PLA microspheres are transferred from the oil to an aqueous solution of calcium chloride, which further tightens the gel shell. The resulting core‐shell microspheres show sustained release of encapsulants for extended periods as the hydrogel shell serves as a diffusion barrier. Moreover, the hydrogel shells prevent interparticle agglomeration and adhesion to the solid walls, securing high suspension stability during the injection.
