Published: July 2023

High power efficiency and low efficiency roll‐off at practical luminance are two requirements for new‐generation energy‐saving lighting technologies, which are still bottlenecks of thermally activated delayed fluorescence (TADF) white organic light‐emitting diodes (WOLED), despite the advantages of TADF materials and devices in low cost and high sustainability. Herein, we developed a spiro phosphine oxide host named SSOXSPO, which can form multiple and multidirectional intermolecular hydrogen bonds (IHB). The resulted multilevel IHB network integrates long‐range ordered and short‐range disordered alignments for suppressing triplet‐polaron quenching (TPQ) and triplet‐triplet annihilation (TTA). Electronic characteristics of SSOXSPO matrix are further regulated, leading to the optimal exciton allocation through balancing energy and charge transfer. As consequence, using SSOXSPO as host, the single‐emissive‐layer TADF WOLEDs realized the record performance, including ultralow operation voltage as ∼4.0 V, power efficiency beyond fluorescent tube (70.1 lm W−1) and negligible external quantum efficiency roll‐off (3%) at 1000 nits for indoor lighting. This work demonstrates that multiple interplays supported by host matrixes in TADF WOLEDs can facilitate the synergistic effects of TADF emitters on 100% exciton utilization.

A comprehensive review of the influence of particle size and pore distribution on the kinetics of CO2 hydrate formation in porous media
Authors: Zhang Xuemin , Li Pengyu , Yuan Qing , Li Jinping , Shan Tao , Wu Qingbai , Wang Yingmei
Published: July 2023

As an essential greenhouse gas, CO2 is the leading cause of global warming and environmental problems. An efficient strategy to lower CO2 emissions is the hydrate‐based method of CO2 geological storage. The stability and formation process of hydrate is the premise and foundation of the hydrate method of CO2 geological storage. However, the formation rule of CO2 hydrate has a significant impact on the formation characteristics of CO2 hydrate. This paper thoroughly examines the formation properties of CO2 hydrate in porous media systems. The quantitative impacts and laws of many parameters on the CO2 hydrate production process are thoroughly examined. On this basis, the internal mechanism of particle size, pore distribution, and critical size of particles in porous media systems on the kinetics of CO2 hydrate formation are detailed. Finally, the shortcomings of the studies on CO2 hydrate formation kinetics in porous media systems and the main directions in the future are pointed out. The influence of pore distribution in porous media on the CO2 hydrate formation process still needs further study. The relative results will be useful in the future for CO2 capture and sequestration in sediments. © 2023 Society of Chemical Industry and John Wiley & Sons, Ltd.
Diels‐Alder Macromolecular Networks in Recyclable, Repairable and Reprocessable Polymer Composites for the Circular Economy – A Review
Authors: Griffini Gianmarco , Rigatelli Benedetta , Turri Stefano
Published: July 2023

In the expanding field of high‐performance materials, polymer‐based thermoset composites play an important role due to their favorably‐high strength/weight ratio and their mechanical performance, thermal stability, and chemical resistance. However, their chemically‐crosslinked nature hampers their re‐processability and efficient recyclability, thus making them not compliant with the principles of the circular economy and of end‐of‐life valorization. Dynamic covalent polymers able to modify their network topology upon thermal stimulus can be considered valid alternatives to commonly used thermosets as they offer advantages in terms of recyclability and reusability, normally not achievable with conventional cross‐linked systems. Within the broad field of dynamic polymers, thermally‐triggered Diels‐Alder based materials represent reliable platforms with enormous technological and industrial potential as repairable, reusable and recyclable matrices in composites given their chemical versatility, suitable mechanical performance and ease of production and processing. In this review, a comprehensive discussion of the most recent demonstrations of the reversibility, reprocessability and recyclablability of such systems is provided, in the context of their use as polymer matrices in composites. It is hoped that this work will stimulate further discussion and research in the area of reversible polymer composites with increased functionality and extended lifetime, in view of their application in future circular economy scenarios.

Cotton (Gossypium hirsutum L.) germplasm lines BARBREN‐713‐8 (Reg. no. GP‐1138, PI 701080), BARBREN‐713‐11 (Reg. no. GP‐1131, PI 701073), BARBREN‐713‐13 (Reg. no. GP‐1132, PI 701074), BARBREN‐713‐25 (Reg. no. GP‐1133, PI 701075), BARBREN‐713‐32 (Reg. no. GP‐1134, PI 701076), BARBREN‐713‐33 (Reg. no. GP‐1135, PI 701077), BARBREN‐713‐41 (Reg. no. GP‐1136, PI 701078), and BARBREN‐713‐48 (Reg. no. GP‐1137, PI 701079) were developed and released by the USDA‐ARS, Texas A&M AgriLife Research, and Cotton Incorporated in 2014. The objective of the release was to provide breeders with agronomically elite germplasm that is resistant to reniform nematode (Rotylenchulus reniformis). Four lines (BARBREN‐713‐8, ‐32, ‐33, and ‐48) also have simple sequence repeat (SSR) DNA markers for the Mi‐1 or Mi‐2 gene for resistance to root‐knot nematode [Meloidogyne incognita (Kolfoid & White) Chitwood]. The lines have excellent seedling vigor in fields infested with both nematodes and fungal root‐rot pathogens. Resistance to reniform nematode was transferred from G. barbadense GB713 (PI 608139) and is associated primarily with the Ren2GB713 gene on chromosome 21. This gene could be detected with the codominant SSR marker BNL3279_105 or the single nucleotide polymorphism marker GI‐187401. In controlled environment assays, these lines reported here suppressed numbers of reniform nematode eggs by 74–92% compared with ‘FiberMax FM966’. The lines outyielded and had fiber quality equal to or greater than several commercial cultivars.
MiR133b‐mediated inhibition of EGFR‐PTK pathway promotes rAAV2 transduction by facilitating intracellular trafficking and augmenting second‐strand synthesis

Published: July 2023

Recombinant adeno‐associated virus (rAAV) is an extremely attractive vector in the in vivo delivery of gene therapy as it is safe and its genome is simple. However, challenges including low permissiveness to specific cells and restricted tissue specificity have hindered its clinical application. Based on the previous studies, epidermal growth factor receptor‐protein tyrosine kinase (EGFR‐PTK) negatively regulated rAAV transduction, and EGFR‐positive cells were hardly permissive to rAAV transduction. We constructed a novel rAAV‐miRNA133b vector, which co‐expressed miRNA133b and transgene, and investigated its in vivo and in vitro transduction efficiency. Confocal microscopy, live‐cell imaging, pharmacological reagents and labelled virion tracking were used to analyse the effect of miRNA133b on rAAV2 transduction and the underlying mechanisms. The results demonstrated that miRNA133b could promote rAAV2 transduction and the effects were limited to EGFR‐positive cells. The increased transduction was found to be a direct result of decreased rAAV particles degradation in the cytoplasm and enhanced second‐strand synthesis. ss‐rAAV2‐miRNA133b vector specifically increased rAAV2 transduction in EGFR‐positive cells or tissues, while ss‐rAAV2‐Fluc‐miRNA133b exerted an antitumor effect. rAAV‐miRNA133b vector might emerge as a promising platform for delivering various transgene to treat EGFR‐positive cell‐related diseases, such as non‐small‐cell lung cancer.

Authors: Luo Mannan , Walton Esther , Neumann Alexander , Thio Chris H. L. , Felix Janine F. , van IJzendoorn Marinus H. , Pappa Irene , Cecil Charlotte A. M.
Published: July 2023

Background

Lateral ventricular volume (LVV) enlargement has been repeatedly linked to schizophrenia; yet, what biological factors shape LVV during early development remain unclear. DNA methylation (DNAm), an essential process for neurodevelopment that is altered in schizophrenia, is a key molecular system of interest.

Methods

In this study, we conducted the first epigenome‐wide association study of neonatal DNAm in cord blood with LVV in childhood (measured using T1‐weighted brain scans at 10 years), based on data from a large population‐based birth cohort, the Generation R Study (N = 840). Employing both probe‐level and methylation profile score (MPS) approaches, we further examined whether epigenetic modifications identified at birth in cord blood are: (a) also observed cross‐sectionally in childhood using peripheral blood DNAm at age of 10 years (Generation R, N = 370) and (b) prospectively associated with LVV measured in young adulthood in an all‐male sample from the Avon Longitudinal Study of Parents and Children (ALSPAC, N = 114).

Results

At birth, DNAm levels at four CpGs (annotated to potassium channel tetramerization domain containing 3, KCTD3; SHH signaling and ciliogenesis regulator, SDCCAG8; glutaredoxin, GLRX) prospectively associated with childhood LVV after genome‐wide correction; these genes have been implicated in brain development and psychiatric traits including schizophrenia. An MPS capturing a broader epigenetic profile of LVV – but not individual top hits – showed significant cross‐sectional associations with LVV in childhood in Generation R and prospectively associated with LVV in early adulthood within ALSPAC.

Conclusions

This study finds suggestive evidence that DNAm at birth prospectively associates with LVV at different life stages, albeit with small effect sizes. The prediction of MPS on LVV in a childhood sample and an independent male adult sample further underscores the stability and reproducibility of DNAm as a potential marker for LVV. Future studies with larger samples and comparable time points across development are needed to further elucidate how DNAm associates with this clinically relevant brain structure and risk for neuropsychiatric disorders, and what factors explain the identified DNAm profile of LVV at birth.

Published: July 2023

Purpose

To evaluate the vertical misfit, stress distribution around dental implants, and cantilever fracture strength of 3‐unit implant‐supported cantilever fixed partial dentures (FPDs) using frameworks made from different materials and manufacturing techniques.

Materials and Methods

Forty FPDs were fabricated and divided into 5 groups (n = 8) based on the framework material used: LAS Co‐Cr (Conventional casting—laser welding); TIG Co‐Cr (Conventional casting –TIG welding); OP Co‐Cr (Conventional casting—one‐piece); CAD Co‐Cr (CAD‐CAM); and CAD Zr (CAD‐CAM ZrO2). The vertical misfit was evaluated before porcelain application (T1) and before (T2), and after thermomechanical cycling (T3) by stereomicroscopy. Cantilever fracture strength was tested with a 50 kN (5000 kgf) load cell at a crosshead speed of 0.5 mm/min. Qualitative and quantitative photoelastic analysis was performed to evaluate stress distribution at seven specific points in five FPDs (n = 1/group) subjected to occlusal loading.

Results

Only the molar showed interaction among the three factors (G × S × T; F(20.932) = 1.630; p = 0.044). Thermomechanical cycling (T2 vs. T3) had a significant effect on intra‐group vertical misfit in molar, especially in LAS Co‐Cr (Δ = 5.87; p = 0.018) and OP Co‐Cr (Δ = 5.39; p = 0.007), with no significant effect in premolar (p > 0.05). Ceramic application combined with thermomechanical cycling (T1 vs. T3) caused a significant intra‐group increase in vertical misfit in all groups, both in the molar and premolar (p < 0.05). OP Co‐Cr was associated with greater vertical misfit and stress concentration. Frameworks manufactured by the CAD‐CAM system exhibited lower vertical misfit and better stress distribution. FPDs with metal frameworks (>410.83 ± 72.26 N) showed significantly higher fracture strength (p < 0.05) than zirconia (277.47 ± 39.10 N), and the first signs of ceramic veneering fracture were observed around 900 N.

Conclusions

FPDs with frameworks manufactured using a CAD‐CAM system appear to be associated with lower vertical misfit and better stress distribution, although the section of the frameworks followed by welding may be a viable alternative. In addition, metal frameworks exhibit high fracture strength.
Effects of Performance and Normalized Parameters on Various Materials Based Multistage Thermoelectric Generator
Authors: Srivastava Kartik , Sahoo Rashmi Rekha
Published: July 2023

Multi-staging and variable cross section greatly improve the performance of thermoelectric generators. Hence, the present theoretical study analyzes a multi-stage-variable-shaped thermoelectric generator (MVS-TEG) for a combination of dissimilar materials. Effects on voltage, power, conversion efficiency, normalized constraints (voltage, power, and conversion efficiency), and second law efficiency with a row number, exhaust inlet temperature, and the coolant flowrate have been investigated. Results reveal that the row number is the most critical input parameter followed by exhaust inlet temperature and coolant flowrate. Also, the work gives optimum values of rows for voltage and power as Nx = 19 for MVS TEG-1, MVS TEG-3, and MVS TEG-4 while Nx = 18 for MVS TEG-2. The exhaust inlet temperature variation increases the voltage and power output by 54–59% and by 53–58% respectively. The coolant flow variation has a greater impact on the conversion efficiency and the average improvement in the efficiency is about 9.23% in the present study. The second law efficiency decreases with the increase in all the input parameters.

Published: July 2023

Glycolate oxidase (GOX) plays an important role in the regulation of photorespiration and photosynthesis in plants. However, as one of the main enzymes to produce the second messenger hydrogen peroxide (H2O2), its functions in response to pathogens are still poorly understood. In this study, we carried out genome-wide identification, and 14 GOX genes were identified in Gossypium hirsutum. These GOX genes are located on 10 chromosomes and divided into hydroxyacid-oxidases (HAOX) and GOX groups. After infection with Verticillium dahliae Kleb., six GOX gene expression levels were changed. Moreover, H2O2, salicylic acid (SA), and the content and activity of GOX increased in cotton. GhHAOX2- D-silenced plants showed more wilting than control plants after infection with V. dahliae. Additionally, H2O2 accumulation and SA content were reduced in GhHAOX2- D-silenced plants. The expression levels of GhPAL, GhPAD4, and GhPR1 and the lignin content of the silenced plants were significantly lower than those of the control plants. These results indicate that GhHAOX2-D is a positive regulator of Verticillium wilt tolerance in cotton and may promote H2O2 accumulation via the synergistic effects of GOX genes and SA. Collectively, GOX genes play an important role in cotton resistance to Verticillium wilt.

We encounter scalar fields everywhere in nature, although some may seem fainter than in the early universe. The models of this field having the logarithmic non-linearity are considered in inflation cosmology and supersymmetric field theories especially Q-ball dynamics model, quantum mechanics and nuclear physics. Till now, numerical studies and theoretical analysis of the considered problems have been studied. Purpose of the study is to obtain the analytical solutions of the Q-ball dynamics model via the ansatz-based method. The results have been seen in the literature for the first time to the best of our knowledge. The resulting solutions are useful in interpreting the study of wave propagation and have many applications in physics and the multidisciplinary audience.

Authors: Kathuria Abhinav , Gupta Anu , Singla R. K.
Published: July 2023

The evaluation of feedback collected from students at the end of the year is very essential for every educational institution. It is important to improve the teaching–learning process and the annual appraisal process. The existing approach utilizes a Likert scale questionnaire, which allows students to express their level of agreement or disagreement with given statements or provide a neutral response. Additionally, the feedback form includes open-ended questions where students can provide textual feedback. This study introduces a Lexicon-based approach to automatically analyze the textual feedback concerning different aspects of teaching. Aspect-based Sentiment Analysis (ABSA) of student feedback aims to identify sentiments expressed toward various aspects of teachers, such as their ability to address student doubts and their overall knowledge. This study explores linguistic characteristics found in sentences, including negation, modifiers and contact shifters. To assess the sentiment of a sentence, the SentiWordNet lexicon is utilized to assign scores to individual words. Based on these scores, the sentence is categorized as either positive, negative or neutral. According to the experimental findings, the Aspect-Oriented Lexicon-Based (AOLB) approach demonstrates superior performance compared to other baseline methods when it comes to accurately scoring sentiment. The approach achieved a high accuracy rate of 94% for the student feedback dataset-I, 74% for the student feedback dataset-II, 55% for laptop reviews and 59% for restaurant reviews in the SemEval 2014 dataset-III.
Renewed Concepts for Electric Charge, Electric Current and Magnetic Charge by the Energy Circulation Theory
Authors: Nagao Shigeto
Published: July 2023

The existing electromagnetism (EM) expects isolated elementary electric charges [Formula: see text] or [Formula: see text], and allows their clusters [Formula: see text]. If such isolated charges were possible, a notable force should have worked between electrodes of batteries. However, we practically cannot detect a force between electrodes of adjacent two cells or those of a capacitor. This is critical and requests a drastic correction of key concepts in EM. According to our proposed energy circulation theory, the electric charge is the momentum in the hidden dimension of the 4D space. The electric force is a presentation of the fundamental force that works based on momentums. The elementary charge [Formula: see text] of an electron is not a point charge but spreads even until its counter such as a proton. Plus and minus charges align alternately with the interval [Formula: see text] same as the diameter of a quantum particle. The elementary charge e is not the minimum charge but the maximum charge. The force within a prolonged electric charge pair is same as that expected by the standard EM. However, the charges at the two ends are as small as about [Formula: see text], and hardly affect an electrostatic force with an outside charge. This is the reason why an electrostatic force does not work between an electrode of a cell and that of another cell. Here in this paper, we claim to express the electric current by the energy of electric polarization instead of the electric charge. As a unit of polarization energy, we newly define the polar charge, by which we express the electric current. We further define the magnetic charge as a momentum in space dimensions of a hidden–space-dimensional energy circulation. It is a vector charge in the 3D space while the electric charge is a scalar charge. We demonstrate how a rotation of magnetic charges is induced and derive the equation of magnetic charge density around the electric current.
Hypocrisy, Knowledge, and the Rule of Blaming
Authors: Eylon Yuval
Published: July 2023

It is commonly accepted that non-hypocrisy is a condition of blaming, and that it is a moral condition. This paper proposes an alternative, epistemic, view of blaming: knowledge is necessary for blaming, and with the added condition that knowledge provides a (motivating) reason for action – sufficient.

First it is argued that knowing that the action of a blamee is wrong is necessary for blaming. Second, it is shown that the phenomenon of hypocritical blaming extends to circumstances not involving moral judgment (such as sports). Third, it is claimed that expressions of intentions such as (1) “A is wrong and I intend to do it” are infelicitous as they stand. The similarities between such expressions and hypocritical blaming recommend a unified account of their infelicity. Finally, it is argued that only the epistemic view of blaming provides accounts for both moral and non-moral blaming, and for the related phenomena.
A Model to Support Collective Reasoning: Formalization, Analysis and Computational Assessment
Authors: Ganzer Jordi , Criado Natalia , Lopez-Sanchez Maite , Parsons Simon , Rodriguez-Aguilar Juan A.
Published: July 2023

In this paper we propose a new model to represent human debates and methods to obtain collective conclusions from them. This model overcomes two drawbacks of existing approaches. First, our model does not assume that participants agree on the structure of the debate. It does this by allowing participants to express their opinion about all aspects of the debate. Second, our model does not assume that participants’ opinions are rational, an assumption that significantly limits current approaches. Instead, we define a weaker notion of rationality that characterises coherent opinions, and we consider different scenarios based on the coherence of individual opinions and the level of consensus. We provide a formal analysis of different opinion aggregation functions that compute a collective decision based on the individual opinions and the debate structure. In particular, we demonstrate that aggregated opinions can be coherent even if there is a lack of consensus and individual opinions are not coherent. We conclude with an empirical evaluation demonstrating that collective opinions can be computed efficiently for real-sized debates.

This research was conducted on the emergence of several controversial government policies and have the possibility of leading to Islamophobia. The purpose of this study is to analyze several controversial policies that are seen from two aspects, namely from the perspective of democracy and Islamophobia. The method used is a literature study by analyzing policies based on a review of related theories. The results of this study are that the policies made by the government, namely the minister of religion, have the possibility of Islamophobia. These controversial policies when viewed from two different perspectives have the potential for greater Islamophobia because they create a bad perception of Islam. In addition, these policies are not based on appropriate democracy, but tend to lead to the personal decisions of policy makers.

Published: July 2023

Diabetes is becoming more and more prevalent, and preventing its occurrence has become a major challenge for society. In response, this article has established a non-invasive pre-diagnostic indicator system for diabetes using the CACP multi-layer data processing framework. The system consists of four main layers: cleaning, analysis, cross-validation, and processing. In the cleaning layer, indicators and subject groups with a high missing rate undergo screening, and missing data is processed through interpolation. The analysis layer analyzes the correlations between indicators of different types and categories, verifies and eliminates highly correlated indicators, and obtains a preliminary screening indicator set. In the cross-validation layer, the primary screening indicator set undergoes further processing to obtain a secondary indicator set. In the processing layer, the normalized and processed data is input into the xgboost classifier to obtain the AUC value and accuracy as a reference. Each indicator in each secondary indicator set is then deleted and processed to select the group of indicators with better results than the control group. Finally, the selected indicators are validated through the processing layer to obtain the best classification performance in the final screening feature set. Using part of the features and classification data from the Nhanes data in 2017-2018, the non-invasive pre-diagnostic indicator system for diabetes can achieve a classification accuracy of 0.91. This system only requires routine physical examination data such as height, weight, blood pressure, and some personal information to achieve autonomous non-invasive pre-diagnosis, making it an effective tool to prevent and treat diabetes.
A study of person re-identification approach utilizing an enhanced ConvNeXt architecture
Authors: Sun Xiaoming , Duan duanyan , Chen Yan , Zhang Junkai , Wang Yongliang , SU Bochao
Published: July 2023

In this paper, we present a new person re-identification method based on an improved ConvNeXt network, called ConvNeXt-AP. This method effectively captures pedestrian features, reduces computing resources, and improves recognition accuracy. ConvNeXt is used as the main network to enhance the capture of local spatial features, with the final forward head module removed to retain more pedestrian features. Moreover, the segmentation strategy from the PCB_RPP network is incorporated at the end of the model to extract fine-grained information from the pedestrian image. To improve the effectiveness of feed-forward convolutional neural networks, the ConvNeXt model Block implements the non-parametric attention mechanism SimAM. This mechanism infers the three-dimensional attention weight of the feature map without adding parameters to the original network, resulting in significant performance improvement with minimal maintenance overhead. To achieve stability and faster convergence, the model achieves stability over time by using a warm-up strategy, and during training, a random erasing strategy is used to reduce the risk of overfitting and improve robustness to occluded pedestrians. Our method has been rigorously tested on multiple public datasets of person re-identification, and the results demonstrate superior performance compared to many state-of-the-art methods.
Enriching Shot Boundary Detection through DT-DWT and Deep Learning Models
Authors: Kumar Neelam
Published: July 2023

Numerous techniques exist for detecting shot or scene boundaries, typically relying on visual characteristics of frames and contrasting said features among adjacent frames to identify shot boundaries. Shot Boundary Detection can utilize a range of visual characteristics such as edge feature, gray intensity, motion vector, and color histogram. The accuracy of Shot Boundary identification methods that currently exist has demonstrated a relatively high level of effectiveness. It is imperative to adapt current techniques to accommodate diverse video content types, as contemporary video productions employ a wider range of video creation methods than their predecessors. The presented approach in this methodology examines the different techniques fr the purpose of achieving the shot boundary detection. The Dual Tree – Discrete Wavelet Transformation approach has been contrasted with the deep learning approaches such as Artificial Neural Network and Convolutional Neural Network. The video is given as input on which frame extraction, feature extraction through Entropy Calculation and Mean Log Estimation is realized with the Deep learning methodologies. The outcomes of the shot boundary identification have been effectively compared with one another to determine performance which is displayed in the later sections of this research article.
Optimizing Deep Neural Networks for Face Recognition to Increase Training Speed and Improve Model Accuracy
Authors: Diba Mostafa , Khosravi Hossein
Published: July 2023

Convolutional neural networks are constantly evolving to achieve higher accuracy in solving different problems; as a result, the computational cost and model size increase. This paper presents a new method for pruning face recognition models based on convolutional neural networks. Our proposed approach identifies and removes ineffective filters based on the volume of the information in feature maps. In each layer, some feature maps do not have information, and there exists a correlation between some feature maps. Filters related to these two feature categories impose additional computational costs on the model; by removing the filters related to these two categories of feature maps, we can reduce the computational cost and size of the model. Our proposed approach uses the combination of correlation and the sum of matrix elements of each feature map to identify and remove inefficient filters. We used two face recognition models with the backbone architecture of VGG16 and ResNet50V2. In the proposed method, the number of removed filters in each layer will be floating, and the removed filters in each layer are independent of the layers before and after them. We initialize the convolutional layers of both backbones with pre-trained weights from ImageNet. We train the proposed algorithm on the CASIA-WebFace dataset and utilize the LFW dataset for benchmarking purposes. In the face recognition model based on VGG16 architecture, we achieved a 1.74% improvement in accuracy while reducing the convolution parameters by 26.85% and decreasing FLOPs by 47.96%. In the case of the face recognition model using ResNet50V2 architecture, we implemented the ArcFace method. Removing inactive filters in this model decreased accuracy by 0.11%. However, this resulted in increased training speed, a reduction of 59.38% in convolution parameters, and a decrease of 57.29% in FLOPs.

Although empathy is understood as a leadership trait, recognition of its worth in the operation of organizations is lacking. Our aim in this study was to examine the relationship between manager empathy and employee innovative behavior by introducing the mediating role of guanxi. Amos
and SPSS were used to test the proposed model comprising data obtained from 275 employees and 112 of their managers in 10 Chinese companies. Results of structural equation modeling revealed that manager empathy was positively related to employee innovative behavior; moreover, guanxi played
a partial mediating role in this relationship. In the context of guanxi culture in China, our findings provide new insights into how employee innovative behavior can be affected by manager empathy, and suggest that managers should improve their empathy skill and build positive guanxi with
employees to enhance employees' innovative behavior.

Published: July 2023

Composite phase-change nanofibers were prepared by electrospinning with polyethylene glycol (PEG) as the phase-change material (PCM) and polyvinylpyrrolidone (PVP) as the carrier matrix. The high PEG content endowed the nanofibers with an excellent cooling effect and significantly reduced the smoke temperature. For PEG70/PVP nanofibers, the smoke temperature can be decreased 45℃ at the 8th puff, and be kept below 45℃. The cooling test proved that the electrospun PEG/PVP phase-change nanofibers exhibited a desirable cooling performance, improving the comfort of cigarette products. And the composite PEG/PVP phase-change nanofibers present great potential as the cooling cigarette filter material for HnB tobacco application.

Left or Right of the Boom? Transforming Defense Budgets into Military Capabilities through an Integrated Defense Planning and Management System
Authors: Constantinescu Maria
Published: July 2023

Defence resources management relies on effective decision processes that underline more than just the process of spending the money from the approved budget. Decision makers should be able to easily trace the amounts spend not only to input items (such as number of airplanes purchased or salary expenses in a military unit), but also to a military capability and the effects produced by its employment. This information is crucial for decision makers to understand and assess the consequences of their decisions (in military, resource and financial terms) and identify options to improve the decisions for the future.
Order of Performance of Obligations
Authors: Brezniceanu Andra Maria
Published: July 2023

The proposed article examines the treatment of the order of enforcement of obligations by parties in Romanian law. The order of performance is a key issue in contracts and can influence the rights and responsibilities of the parties involved. According to the Romanian Civil Code, the order of performance of obligations can be determined by agreement of the parties or by applicable legal provisions. Thus, the parties may expressly stipulate in the contract the order in which they are to perform their obligations. If the contract does not provide for such an order, the Civil Code provides general principles and rules for determining the priority of performance of obligations. In practice, compliance with the order of performance of obligations may be essential if one of the parties does not fulfil its contractual responsibilities. If one party fails to perform its obligation in accordance with the established order, the other party may claim non-performance of the contract and seek termination, damages or other remedies available under the law. It is therefore crucial that parties pay particular attention to establishing and respecting the order of performance of obligations in contracts. This will help to avoid disputes and provide a clear and predictable framework for contractual relations. In conclusion, the order of performance of obligations in Romanian law is an important issue in contracts. Both by agreement of the parties and by application of the general rules, the aim is to establish a clear hierarchy of contractual obligations. Compliance with this order can protect the interests of the parties and facilitate the efficient resolution of disputes in the event of non-compliance with the contract.

Harmonization of the Legal System with the Moral System - Essential Condition for the Positive Evolution of the University Environment
Authors: Drăghici Teodora Aurelia , Ilie Oana-Antonia
Published: July 2023

It is affirmed that the highest stage of human evolution will be reached when what is considered illegal will also be considered immoral and what is appreciated as legal will also be of moral value. In another expression, this desideratum requires that morality is in an identity relationship with legality, or it is the proximate type of legality, and immorality is the proximate type of illegality. In the circumstances of a globalized world where there are already laws that operate on an international scale and common values, such as social solidarity and international cooperation, the recognition of these fundamental values does not imply agreement on the common ground of understanding in terms of justice and morality. The University has a duty to assess how its students perceive morality and legality, but it also has the power to grow these values and foster an environment where they serve as a constant source of guidance for students. The quality of the content of the legal norms, as well as their harmonization with the moral norms will result in an ethical university environment where there will be no more differences between the moral and legal systems, or they will be negligible, when all or almost all of the system of rules that make up morality will be integrated into the legal system, there being no immoral legal rules.
The Impact of the Dynamics of Services on the Economic Use Value of Historical Monuments. Case Study: the Municipality of Bucharest

Heritage buildings represent elements of territorial identity of the cities due to the multiple valences they incorporate (historical, architectural, artistic, and cultural). Due to the particular characteristics of the built heritage, multiple possibilities of reuse are associated with it. Thus, the evaluation of the economic use value of heritage buildings is justified. This work aims to evaluate the economic use value of historical monuments located in the protected urban area C.A. Rosetti-Maria Rosetti-Popa Petre, located in the central part of Bucharest. The main results of the paper reveal the fact that the multiple forms of reuse of heritage buildings in the analyzed protected urban area are under the impact of the accelerated dynamics of services (commercial spaces, office spaces, hotels). Some reuses affect the architectural value of historical monuments through interventions that involve modifying the exterior architecture or the character/valuable elements of the interior, as well as a higher regime of height than the neighborhood average, which also generates discontinuities in the historical urban fabric.
Critical Reading - A Fundamental Skill for Building 21st Century Literacy
Authors: Niculescu Brânduşa-Oana , Dragomir Isabela-Anda
Published: July 2023

Academic expectations are a game changer when it comes to students’ learning experiences. As part of their university studies, learners are asked to read research, articles, textbooks, lecture notes, etc., and critically engage with the content in order to analyze it, evaluate it, make connections, draw conclusions, or find new ways to reorganize, reinterpret, and recycle information. Learning to read critically helps students navigate the deep waters of academic requirements, and will ultimately empower them to function more effectively in the educational environment and beyond. This article presents critical reading as an essential skill whose mastery will enable students to deepen their understanding and awareness of both language and content. By discussing critical reading skills from the perspective of traditional and modern approaches and by deconstructing this receptive ability from the point of view of the various strategies and techniques it entails, the present paper aims to address useful aspects related to both the theoretical fundamentals and the practical construction of critical reading competence, and to highlight the importance of critical thinking skills as essential prerequisites for building 21st century literacy.
Mürsel Sönmez’in Divân-ı Niyâz Adlı Eserinde Söz Oyunları ve Geleneğin Şiir Diline Yansımaları
Authors: ÖZTÜRK Sevilay , FEDAİ Özlem
Published: July 2023

Dil; içerisinde barındırdığı farklı işlevlerle çağlar boyunca duygu ve düşünce aktarımının temeli olmuştur. İmgelerden, duygulardan düşlerden oluşan bir birikiminin ürünü olan şiirin dili ise dilin tüm imkânlarını barındırarak onu estetize eder. Paul Valery’ye göre “dil içinde ayrı bir dil” olan şiir dilinde; şairin duygu ve hayal dünyasıyla biçimlenen özel bir dil vardır. Bu çalışmada, 1980 sonrası Türk şiirinde kendine has şiir diliyle dikkat çeken şairi Mürsel Sönmez’in Divân-ı Niyâz adlı eseri, şiir dili, kelime serveti ve söz oyunları açısından değerlendirilmiş, bu eserden hareketle şairin şiirlerindeki duygu ve hayal dünyasının boyutları ortaya koyulmaya çalışılmıştır. Eser, biçim ve öz itibari ile geleneğin bilhassa Divan şiirinin dünyasını yansıtırken sahip olduğu söz varlığı ile şairinin zengin hayal dünyasını sergilemektedir. Sanatçının gelenekten faydalanması sadece şiirlerinin formunu etkilememiş Türkçeyi kullanma biçimine de etki etmiştir. Biçim ve içerik olarak gazel, kaside, na’t örnekleri yer almaktadır. Şairin eserdeki şiirleri biçimsel formları ve modern zamanların dilini yansıtmaları bakımından gelenek ile modern zamanların şiiri arasında bir köprü oluştururlar. Eserde özellikle bir na’t örneği taşıyan “Efendim” şiirinin bile tek başına sahip olduğu söz varlığı ile Türkçeye nasıl katkı sağladığı gözler önüne serilmiştir. İncelememiz sonucunda şairin özelde Divan-ı Niyaz adlı eserinde genelde ise tüm şiirlerinde “geleneğin kökleri”yle “gelecek”i birleştirme gayreti içinde olduğu anlaşılmış, bu hususta da şairin söz oyunlarının, kelime dünyasının etkili olduğu görülmüştür. Eserde şairin tercih ettiği kelimelerin bugünün dünyasınca açık ve anlaşılır olmasına karşılık taşıdıkları anlam derinliği bakımından zengin çağrışımlarla yüklü oldukları, Sehl-i mümteni, Tevriye gibi sanatlar barındırdıkları örneklerle ortaya konulmuştur. Çalışmamızda sanatçının söz konusu eserinde tespit ettiğimiz söz varlığı, şiir dilinin edebî zenginliğini, başka metinlerle kurduğu metinlerarası ilişkileri de gözler önüne sermektedir. Nitel bir araştırma yöntemi olan doküman incelemesi yöntemi ile gerçekleştirilen çalışmamız sonucunda 1980 sonrası Türk şiirinin güçlü kalemi Mürsel Sönmez’in gelenekten ve tasavvuftan beslenen, inançlı bir şiir dünyasına sahip olduğu şiir dilinin zenginliğine paralel olarak ortaya çıkarılmıştır.
Kırmızı ve Siyah romanı ile Mai ve Siyah romanlarında renkler üzerine bir inceleme
Authors: GÜLŞEN Hacer
Published: July 2023

Bu makalede Fransız edebiyatında realizm akımının en önemli temsilcilerinden biri olan Stendhal’ın Kırmızı ve Siyah romanıyla, Halit Ziya’nın Mai ve Siyah romanı renkli dünyalarıyla ele alınmaktadır. Bilindiği gibi Türk yazarları Fransız edebiyatının seçkin eserlerinden etkilenmişlerdir. Bu etki çok uzun bir zaman devam etmiştir. Realizm akımının en önemli temsilcilerinden biri olan Stendhal da Türk romanının modernleşmesinde büyük katkıları olan Halit Ziya'yı etkilemiş yazarlardan biridir. Her iki romanda da sosyal meseleler ferdi ıstıraplardan daha çok önem taşımaktadır. 19. Yüzyılın ilk ve ikinci yarısının sosyal meselelerinin dikkat çektiği bu romanlarda her iki yazar da Julien Sorel ve Ahmet Cemil’in şahsında bir devir romanı inşa etmişe benzerler. Siyah her iki romanda da ortak tek renktir. Mai ve Siyah’ta hayal kırıklığını Kırmızı ve Siyah romanında ise ruhban sınıfını ve kiliseyi simgelemektedir. Bu çalışmada kullanılan yöntem Karşılaştırmalı edebiyat yöntemidir. Bu yöntemle her iki romanın benzerlikleri ve farklılıkları ortaya çıkacaktır. Ancak asıl önemli olan renklerin taşıdığı anlamın ve bu renklerle anlatılmak istenenlerin ortaya çıkarılmasıdır.
