Employees' geographic social identity and group pro‐environmental behaviors: Cross‐cultural evidence from 45 countries
Authors: Zeng Kevin J. , Yu Irina Y. , Tso Scarlet H. , Yang Morgan X. 
Published: December 2022

AbstractEmployees' group pro‐environmental behaviors (PEBs) represent employees' collective efforts to combat critical global environmental problems. Drawing on social identity theory, we examined how employees' group PEBs can be inspired by different forms of geographic social identity (i.e., world identity, national identity, and regional identity). We analyzed data from the most recent (seventh) wave of the World Value Survey (2017–2022), which covers 34,951 employees from 45 nations. We found that employees' world identity contributed more than their regional identity and national identity to their engagement in group PEBs, by inducing a green orientation that prioritized environmental protection over economic growth. In addition, we obtained cross‐country evidence that the effect of world identity on green orientation is more pronounced in individualist than in collectivist societies. Our findings help to resolve inconsistencies in prior research regarding the theoretical link between social identity and PEBs and provide actionable insights for academics, practitioners, and policymakers seeking to facilitate group PEBs in organizations.

Published: December 2022

AbstractMost of the corpus callosum (CC) developmental studies are concerned with its two‐dimensional structure. Linear and area measurements do not directly assess the CC size but estimate the overall structure from the cross‐sectional image. This study investigated age‐ and sex‐related changes in volumetric development and asymmetry of CC from birth to 18. For this retrospective study, we selected 696 patients (329 [47.27%] females) with both 3D‐T1‐weighted sequence and normal radiological anatomy from patients 0–18 years of age who had brain magnetic resonance imaging (MRI) between 2012 and 2020. The genu, body, splenium, and total volume of CC were calculated using MRICloud. The measurement results of 23 age groups were analyzed with SPSS (ver.28). Total CC volume was 18740.76 ± 4314.06 mm3 between 0 and 18 years of age, and its ratio to total brain volume (TBV) was 1.70% ± 0.23%. We observed that the total CC volume has six developmental periods 0 years, 1, 2–4, 5–9, 10–16, and 17–18 years. Genu and body grew in five developmental periods, while splenium in seven. There was intermittent sexual dimorphism in the CC volume in the first 4 years of life (p < 0.05). However, sex factor was insignificant in CC ratio to TBV. Total CC was right lateralized on average 1.81% (ranging −0.59% to 4.52%). Genu was 8.70% lateralized to the right, the body was 2.99% to the left, and the splenium was 1.41% to the right. The three‐dimensional development of CC agreed with the two‐dimensional developmental data of CC except for some differences.

AbstractThe arteries of the lower limbs are innervated by vascular branches (VBs) originating from the lumbar sympathetic trunk and branches of the spinal nerve. Although lumbar sympathectomy is used to treat nonreconstructive critical lower limb ischemia (CLLI), it has limited long‐term effects. In addition, the anatomical structure of tibial nerve (TN) VBs remain incompletely understood. This study aimed to clarify their anatomy and better inform the surgical approach for nonreconstructive CLLI. Thirty‐six adult cadavers were dissected under surgical microscopy to observe the patterns and origin points of VBs under direct vision. The calves were anatomically divided into five equal segments, and the number of VB origin points found in each was expressed as a proportion of the total found in the whole calf. Immunofluorescence staining was used to identify the sympathetic nerve fibers of the VBs. Our results showed that the TN gave off 3–4 VBs to innervate the posterior tibial artery (PTA), and the distances between VBs origin points and the medial tibial condyle were: 24.7 ± 16.3 mm, 91.7 ± 66.1 mm, 199.6 ± 52.0 mm, 231.7 ± 38.5 mm, respectively. They were mainly located in the first (40.46%) and fourth (31.68%) calf segments, and immunofluorescence staining showed that they contained tyrosine hydroxylase‐positive sympathetic nerve fibers. These findings indicate that the TN gives off VBs to innervate the PTA and that these contain sympathetic nerve fibers. Therefore, these VBs may need to be cut to surgically treat nonreconstructable CLLI.

AbstractThe traditional Chinese medicine of fermented medicine may be under the involvement of multiple strains and the interaction between these microorganisms. Liu Shenqu (Massa Medicata Fermentata, MMF) is one of the most widely used fermented medicines, whose potential processing mechanism is still unclear. In this work, UPLC/MS and GNPS methods were employed to rapidly predict chemical compositions in MMF. Moreover, the dynamic changes of strains, chemical compositions and anti‐inflammatory activity of MMF during fermentation process were investigated, and subsequently strains‐chemical compositions‐efficacy interactions were revealed by Pearson correlation analysis and partial least squares regression (PLSR) analysis. As a result, 24 components were identified, and the potential strains including Bacillus, Burkholderia_Caballeronia_Paraburkholderia, Enterobacter, Aspergillus heterocaryoticus, Rhizopus arrhizus, Kazachstania bulderi, which related to the production of anti‐inflammatory active ingredients were exposed. These results demonstrated chemical compositions‐strains‐efficacy interactions during fermentation of MMF, and provide reference for the exploration of the processing mechanism of MMF.

Published: December 2022

AbstractSelective oxidation of methane to oxygenates using low‐cost and environment‐friendly molecular oxygen (O2) under mild reaction conditions is a promising strategy but still remains grand challenge. It is of great importance to accelerate the activation of O2 to generate highly active oxygen species, such as hydroxyl peroxide and hydroxyl species to improve catalytic performance for selective oxidation of methane. Selective oxidation of methane using O2 by coupling with in situ generation of hydrogen peroxide via tandem catalysis ensures the easy formation of active oxygen species for methane activation, leading to high oxygenates productivity under mild conditions. In this concept, we summarized the recent progresses for selective oxidation of methane to oxygenates using O2 based on tandem catalysis by coupling with in situ generation of hydrogen peroxide. The remaining challenges and future perspectives for selective oxidation of methane to oxygenates via tandem catalysis were also proposed.

AbstractCharge‐transfer (CT) engineering with inter‐/intramolecular CT interactions by simple compositions has emerged as a universal and efficient way to construct organic functional materials. Stable organic radicals with unique physicochemical properties that cannot be realized in closed‐shell molecules, have been widely demonstrated to be ideal building blocks to construct versatile organic CT materials. This concept article provides a brief overview of the advances in the design, structure and property of stable organic radicals‐based CT molecular functional materials, and the strategy for the generation of these materials is also highlighted. First, radicals are introduced as open‐shell donors or acceptors, with a focus on their importance and uniqueness in improving electrical, magnetic and optical properties of CT functional materials. Additionally, CT interactions in stable radical dimers and trimers are further discussed systematically. Finally, the challenges are summarized and perspectives for future development of stable organic radicals‐based CT functional materials are provided.

Published: December 2022

AbstractIntelligent fault diagnosis method is an important tool for ensuring the stability of industrial processes. However, in the actual industrial process, forming a fault diagnosis model with good performance is difficult because of the complexity of feature extraction and the lack of labelled fault data. Data enhancement on the basis of the original data is important. To address this problem, this study proposes a method called self‐attention embedded generative adversarial network combined with a residual network (SAGAN‐ResNet). First, to address the lack of fault data, the data augmentation method consisting of the self‐attention embedded generator and discriminator is adopted. Then, to extract the features for better diagnosis performance, the residual network (ResNet) is introduced based on the augmented training dataset. A comparison of the proposed method with others shows that it has advantages in the case of complex process fault diagnosis with few‐shot industrial data.
Synthesizing and comparing the different effects between internal and external corporate social responsibility perceptions and organizational citizenship behavior: A need theory perspective

Published: December 2022

AbstractThis study examines the comparative effects of internal and external CSR perceptions on organizational citizenship behavior (OCB) and focuses on two consequences to compare CSR perception types. It also attempts to develop logical linkages between CSR perceptions and OCB through individual‐level psychological mechanisms, perceived external prestige, and affective commitment. The study is centered around the Chinese manufacturing and service industries using an online data‐collection platform similar to Qualtrics. The structural equation modeling technique was based on 200 supervisor/subordinate dyads. The quantitative analysis utilized SPSS and AMOS software. Results demonstrate that internal CSR perception has more benefits for OCB than external CSR perception. Since internal CSR inputs are often neglected by companies, results provide scholars and managers with a new view to pay attention to the potential of internal CSR inputs.

AbstractEfficient cleavage of β‐O‐4 bonds in lignin to high‐yield aromatic compounds for the potential production of fuels and chemicals is vital for the economics of the modern biorefinery industry. This work is distinct in that a detailed mechanistic analysis of the reaction pathways of veratrylglycero‐β‐guaiacyl ether (VGE) catalyzed by transition‐metal‐free solid acid zeolite in aqueous conditions at high hydrogen pressure has been performed. VGE degradation produced high monomers yields (≈87 %), including guaiacol (48.2 %), 1‐(3,4‐dimethoxyphenyl)ethanol (10.3 %), 1‐(3,4‐dimethoxyphenyl)‐2‐propanol (6.1 %), 3,4‐dimethoxyphenylpropanol (4.7 %), 3,4‐dimethoxycinnamyl alcohol (4.1 %), and 1,2‐dimethoxy‐4‐propylbenzene (2 %). The products were identified and confirmed by the in situ solid‐state magic angle spinning (MAS) 13C NMR spectroscopy in real‐time conditions and the two‐dimensional gas chromatography (GC×GC). A variety of products reveal the crucial role of hydrogen, water, and acid sites for heterolytic cleavage of the β‐O‐4 bond in VGE. Decarbonylation, hydrogenolysis, hydrogenation, and dehydration reaction pathways are proposed and further validated using first‐principles calculations.

AbstractHerein, a novel conducting polymer complex PEDOT:CF3SO2(x)PSS(1‐x) [denoted as S‐PEDOT:CF3SO2(x)PSS(1‐x), where PEDOT is poly(3,4‐ethylenedioxythiophene) and PSS is poly(styrene sulfonate)], is fabricated with the assistance of zinc di[bis(trifluoromenthylsulfonyl) imide][Zn(TFSI)2] (CFE). The introduction of CF3SO2− group is expected to bring better stability of PEDOT:CF3SO2 than PEDOT:PSS due to its strong Coulomb force. Electrochemical measurement shows that a high specific capacitance of 194 F cm−3 was achieved from the novel complex S‐PEDOT:CF3SO2(x)PSS(1‐x), the highest value reported so far. An all‐solid‐state supercapacitor assembly with a structure of S‐PEDOT:CF3SO2(x)PSS(1‐x)/H2SO4:polyvinyl alcohol (PVA)/S‐PEDOT:CF3SO2(x)PSS(1‐x) shows a record specific capacitance of 70.9 F cm−3 and a maximum energy density of 6.02 mWh cm−3 at a power density of 397 mW cm−3. This supercapacitor device demonstrates excellent electrochemical stability with a capacitance retention rate of 98 % after 10 000 cycles and extreme air stability of 96 % capacitance retention rate after 10 000 cycles, even if the device is exposed to air over 2880 h, much better than that of PEDOT:PSS based supercapacitors. Excellent capacitance can be achieved from PEDOT:CF3SO2(x)PSS(1‐x) electrode under electrolyte‐free conditions. This work provides a novel method for high performance stable supercapacitors and may pave the way for the commercialization of PEDOT based supercapacitors.

Published: December 2022

SummaryTemperature is a dynamic variable in most electronic devices. As the device operates, it generates heat, which translates in a temperature increase. Available models commonly disregard these variations due to the fact that they manifest at very large time scales. However, temperature dynamic effects have profound implications on the device model and on our common understanding. This paper discusses implications of considering the temperature variations on the current–voltage characteristic curves of power light‐emitting diodes. The main theoretical results establish that the current equation has a memristive nature when temperature is assumed as a dynamical state variable. This hypothesis is then validated experimentally.

Published: December 2022

SummaryThe deployment of mobile systems is facing several challenges. Precisely, the lack of available licensed bands limits the network capacity, affecting the quality of service (QoS). Consequently, there has been significant interest in utilizing the unlicensed spectrum for mobile data traffic. 3GPP proposed and improved the coexistence of LTE and Wi‐Fi in the unlicensed band starting in Release 13 and the following releases, such as LTE‐LAA and 5G NR‐U. This will cause significant interference and drastically affects the Wi‐Fi users' QoS. To that end, we propose the use of time‐domain virtualization between 5G NR‐U and Wi‐Fi systems. In particular, a scheduling algorithm is proposed, where the sharing mechanism is allocated in time slots rather than allocating a subband frequency for each technology. 5G use cases have different QoS requirements and our proposed solution aims at meeting these requirements. Accordingly, the performance is evaluated by studying the impact of resource virtualization and the coexistence configuration. Simulation results confirm that the minimum rate and maximum delay constraints are met. Moreover, it is shown that resource virtualization improves the throughput in both technologies. Furthermore, the delay performance is displayed for both 5G NR‐U and Wi‐Fi to show any impact of time‐sharing coexistence.

Published: December 2022

AbstractSeveral subsets of mononuclear phagocytes and DCs (MDC) populate the small intestine (SI), and these cells reportedly exert specialized functions in anti‐microbial immunity and tolerance. Given the specialized phenotype of these cells, differing from other MDC family members, including their putative circulating blood precursors, local intestinal factors play key instructive roles in their differentiation. We designed an SI cell culture model composed of three intestinal epithelial cell (IEC) types, including absorptive enterocytes (E cells), antigen delivering microfold (M) cells, and mucus‐producing goblet (G) cells plus T lymphocytes and soluble B cell‐derived factors. This model was used to study the differentiation fate of CD34+ hematopoietic progenitor cell‐derived monocyte/DC precursors. Progeny cells can be analyzed after a 3‐week co‐culture period, mimicking the physiologic turn‐over time of intestinal MDC. A dominant monocyte differentiation pathway was suppressed, in favor of partial differentiation along DC and macrophage pathways, with low percentages of cells acquired DC or macrophage markers. Moreover, E and G cells play opposing roles in CX3CR1+ vs CD103dim cell differentiation, indicating that both together might counter‐balance M/DC differentiation. Thus, SI epithelial cells suppress M/DC differentiation, supporting a key role for exogenous factors in M/DC differentiation.

Published: December 2022

AbstractThe dependence of perovskite‐based photovoltaic devices on toxic solvents limits their applications. Therefore, we added polyoxometalates into ionic liquids, as the green solvent and polyoxometalates synergistically improve the performance of devices. Firstly, methylammonium formate (MAFa) as solvent delayed the crystallization process of perovskite thin films, thus obtained an extended crystal domain, and the photocurrent of the device was increased from 35.51 μA to 63.18 μA. Secondly, introducing PW12 into this green solvent system, the matched energy level and good electron transmission rate promoted the separation of photogenerated excitons and accelerated the transmission of photogenerated electrons in perovskite. After dual adjustment of MAFa and PW12, the photocurrent of the champion device reached 95.99 μA (about 2.7 times of the original device), the unpacked devices can still maintain 80 % of initial value after being placed under environmental conditions for 700 h.
A Comparative Study on Response Surface Optimization of Supercritical Fluid Extraction Parameters to Obtain Portulaca Oleracea Seed Oil with Higher Bioactive Content and Antioxidant Activity Than Solvent Extraction

Published: December 2022

AbstractPortulaca oleracea (purslane) seed oil is a rich source of omega‐6 and omega‐3 fatty acids. Extraction of the purslane seed oil while preserving its high nutritive quality has been a challenge since conventional solvent extraction has many adverse effects on bioactive content. This study aims the optimization of purslane seed oil supercritical fluid extraction (SFE) conditions and to compare purslane seed oils obtained with SFE and conventional solvent extraction in terms of oil yield, along with the purslane seed oil quality and bioactive content. For this purpose, the SFE process parameters (pressure, temperature, static time, and dynamic time) are optimized for oil yield, omega‐6, omega‐3, and antioxidant activity using response surface methodology (RSM). Optimum SFE pressure, temperature, static time, and dynamic time levels are determined as 350 bar, 50 °C, 20 min, and 90 min, respectively. Oil yield and physicochemical quality properties of conventional solvent extract and SFE samples are determined and compared. Consequently, samples obtained via SFE and solvent extraction have similar quality properties. Distinctly, SFE allows an extraction with 5.6% higher total phenolic compound (TPC) and 33% higher antioxidant activity than solvent extraction.Practical Applications: In the study, the extraction of purslane oil using supercritical fluid extraction is optimized with different approaches. At optimum conditions, purslane oil is extracted and all physicochemical properties and the process efficiency (yield) are compared with the solvent‐extracted samples. The results of this study make supercritical fluid extraction of purslane seed oil possible since all optimum operating conditions of a pilot‐sized extractor are reported in the study. It is believed that the results provide a good starting point for industrial operations. Moreover, researchers also believe that research studies unveiling the new potential oil‐bearing seeds are important to overcome the vegetable oil shortage that emerged this year.
A computational study on the optimization of transcranial temporal interfering stimulation with high‐definition electrodes using unsupervised neural networks
Authors: Bahn Sangkyu , Lee Chany , Kang Bo‐Yeong 
Published: December 2022

AbstractTranscranial temporal interfering stimulation (tTIS) can focally stimulate deep parts of the brain related to specific functions using beats at two high frequencies that do not individually affect the human brain. However, the complexity and nonlinearity of the simulation limit it in terms of calculation time and optimization precision. We propose a method to quickly optimize the interfering current value of high‐definition electrodes, which can finely stimulate the deep part of the brain, using an unsupervised neural network (USNN) for tTIS. We linked a network that generates the values of electrode currents to another network, which is constructed to compute the interference exposure, for optimization by comparing the generated stimulus with the target stimulus. Further, a computational study was conducted using 16 realistic head models. We also compared tTIS with transcranial alternating current stimulation (tACS), in terms of performance and characteristics. The proposed method generated the strongest stimulation at the target, even when targeting deep areas or performing multi‐target stimulation. The high‐definition tTISl was less affected than tACS by target depth, and mis‐stimulation was reduced compared with the case of using two‐pair inferential stimulation in deep region. The optimization of the electrode currents for the target stimulus could be performed in 3 min. Using the proposed USNN for tTIS, we demonstrated that the electrode currents of tTIS can be optimized quickly and accurately. Moreover, we confirmed the possibility of precisely stimulating the deep parts of the brain via transcranial electrical stimulation.
