The Impact Of Perceived Social Support On The Academician's Flourishing While Mediated By The Organizational Identification
Authors: Quratulain Memon,  , Dr Irma YazreenbintiMd Yusoff  
Published: October 2023

This study aimed to evaluate the direct and indirect impacts of perceived social support on the flourishing of academic professionals. Based on pertinent research, it has been shown that academicians' perspectives on organizational identification serve as mediating factors in investigating the indirect connections between these two constructs. A structural equation model has been developed and validated using suitable statistical techniques, with organizational identification as the foundation. Four study hypotheses were formulated based on the theoretical frameworks of social exchange and social identification theory. These hypotheses encompass the direct influence of perceived social support on academicians' flourishing and the indirect effect of organizational identification acting as a mediator. The present study examined the mediating function of organizational identification in the relationship between perceived social support and academician flourishing after identifying the interactions among variables. Relevant statistical approaches such as partial least squares structural equation modeling (PLS-SEM) were employed to analyze the data. The study employed many statistical techniques, including data analysis, reliability testing, item-total correlation analysis, regression analysis, and the t-test. The study's findings indicate sufficient supervisor and organizational support at higher educational institutions in Sindh, Pakistan, which considerably impacts academicians' flourishing. However, it was observed that co-worker support does not play a significant role in contributing to their flourishing. The results of this study indicate that organizational identification serves as a partial mediator in the association between supervisor support and organizational support.
Nevertheless, organizational identification did not demonstrate any mediating influence in the correlation between co-worker support and the flourishing of instructors. The present study utilizes a theoretical and structural model to examine the perceived social support (supervisor, co-worker, and organization), employee flourishing, and organizational identification among faculty members at Public sector higher educational institutions in Sindh, Pakistan. Therefore, it is recommended that targeted measures be used to provide authentic relational support inside Pakistani higher education institutions by implementing coaching initiatives, establishing discussion forums, providing orientations, and implementing learning programs. These measures aim to promote academicians' well-being and professional development in higher education institutions.

Authors: Saber Safaa , Salem Sara 
Published: October 2023

Over the last few decades, researchers have paid attention to finding an effective and efficient metaheuristic algorithm that can determine the ideal parameters for PV models. In this study, to determine the TDM’s nine unknown parameters, we will examine the efficacy of a recently proposed metaheuristic algorithm called light spectrum optimizer (LSO). To further enhance the effectiveness of LSO in estimating those unknown parameters, a new improved variant called ILSO is developed. This variant employs LSO in conjunction with two newly developed update systems to improve its exploration and exploitation operators. We compare the best fitness value, worst fitness value, average fitness, standard deviation, and p-value returned by the Wilcoxon rank-sum test obtained by LSO and ILSO to those of three recently published competitors when estimating the nine unknown parameters for the Photowatt-PWP201 module and the RTC France solar cell. The experimental findings show that ILSO is the most efficient.

Authors: Sodje JDK  , Ezeanochie MC  
Published: October 2023

Context: Contraceptive prevalence in Nigeria is low at 17%. Amongst Nigerian women and couples who accept to use contraception, the IUCD is the most commonly used contraceptive method with variation in rates of use between geographical areas and among Health Institutions. Factors that determine decision making on IUCD use are not well understood.
Aims: To study the use, effectiveness, complications and discontinuation rates for intrauterine contraceptive device received at the University of Benin Teaching Hospital from 1997 to 2016 and analyzed in January, 2019.Study Design: This was a retrospective cross sectional study.
Methodology: The case notes of all 3326 new clients who accepted Copper T intrauterine contraceptive device at the UBTH Family Planning Clinic during the review period were retrieved and analyzed. Data regarding acceptors socio-demographic characteristics, side effects, effectiveness, complications, duration of use and reasons for discontinuation were extracted and entered into SPSS for windows version 22.0 and analyzed.
Results: Out of the 8203 clients that accepted to commence a family planning method, 3326 (40.55%) accepted to use IUCD. The mean age of IUCD acceptors at commencement was 33.4±5.60 and the mean age of their husbands was 39.85±6.91. The mean parity was 3.73±1.87 (range 0-12), while the mean number of living children was 3.56±1.66 (range 0-10). The mean duration of use (in months) was 40.43±40.13. Women with 5 or more children (P Value 0.000) and at least a minimum of secondary education (P Value 0.000), were significantly associated with IUCD use duration of > or more than 2 years. Also, women who reported satisfaction with IUCD (P Value 0.000) and no complications (P Value 0.000) were also associated with longer duration of use.
Conclusion: IUCD is a common family planning method used by women at UBTH. Its duration of use is higher among clients with more children, at least a minimum of secondary school education and no complications from its use. This information is relevant for family planning service providers to increase contraceptive uptake by women in Nigeria.

Published: October 2023

Aims: Content analysis of newspapers covering the alcohol sales bans during Covid-19 in South Africa.
Methods: Mixed method content analysis of the highest circulated, paid for, English language newspapers published by four newspaper outlets in South Africa, between 26 February to 26 September 2020 (seven months).
Setting: South African Bibliographic Information Network (Sabinet) and Arena Holdings Media databases were used.
Participants: 317 newspaper articles were identified for analysis from four newspapers: Sunday Times (Arena Holdings), Daily Sun (Naspers), The Star (Independent Media) and the Mail and Guardian (Media Development Investment Fund).
Measures: Qualitative data: a structured coding frame was used to identify themes. Quantitative data: date, agency, placement/page number in the newspaper, number of graphics, words in heading and in article and whether the article was based on opinion or fact. The media vectors: framing, responsibility and newspaper media exposure were calculated.
Findings: Articles were predominantly unfavourable toward the alcohol sales bans, indicated that government should take responsibility for prevention of harmful alcohol use, and focused mainly on the negative economic impact of the alcohol sales bans.
Conclusions: News agencies should make a concerted effort to ensure balanced reporting on matters of health and put measures in place to prevent undue influence on journalists by large corporations, such as the alcohol industry.

ObjectiveWe aimed to advance understanding of how persons with rheumatoid arthritis (RA) experience decision‐making about adopting public health measures during the COVID‐19 pandemic.MethodsPersons living with RA partnered throughout this nested qualitative study. One‐to‐one semistructured telephone interviews were conducted with participants with RA between December 2020 and December 2021. They were strategically sampled from a randomized controlled trial that was underway to test a physical activity counseling intervention. Analysis was guided by reflexive thematic analysis.ResultsThirty‐nine participants (aged 26–86 years; 36 women) in British Columbia, Canada were interviewed. We developed three themes. Participants described how their decision‐making about public health measures related to 1) “upholding moral values of togetherness” because decisions were intertwined with moral values of neighborliness and reciprocity. Some adapted their self‐care routines to uphold these moral values; 2) “relational autonomy—supports and challenges,” because they sometimes felt supported and undermined in different relational settings (eg, by family, local community, or provincial government); and 3) “differing trust in information sources,” in which decisions were shaped by the degree of faith they had in various information sources, including their rheumatologists.ConclusionAcross themes, experiences of decision‐making about public health measures during the pandemic were embedded with moral concepts of solidarity, autonomy, and trust, with implications for how persons with RA chose and sustained their self‐care activities. Insights gained help sensitize researchers and clinicians to moral issues experienced by persons with RA, which may inform support for self‐care activities during and after the pandemic.

AbstractDeveloping high‐capacity conversion‐type anodes with superior durability substituting conventional graphite anodes is urgently desired to improve the energy density of lithium‐ion batteries (LIBs). However, fatal capacity decay during cycling of the conversion‐type anodes, which is primarily due to their inevitable structural degradation and continuous solid‐electrolyte interphase reformation induced by drastic volume change, has highly restricted their commercialization. And, the interrelated effects of phase transformation, structural evolution, and electrochemical characteristics of the conversion‐type anodes during cycling remain poorly understood. Herein, the findings on the fabrication and understanding of a previously unexplored entropy‐stabilized spinel oxide, (Co0.2Mn0.2V0.2Fe0.2Zn0.2)3O4 as a promising conversion anode for LIBs, exhibiting not only moderate volume change character but also highly reversible capacities of ≈900 mAh g−1 for 500 cycles at 0.2 A g−1 and ≈500 mAh g−1 for 2000 cycles at 3 A g−1, respectively, are reported. Evidenced by in situ transmission electron microscopy coupled with theoretical calculations, its underlying mechanism underpinning highly reversible Li storage is explicitly revealed, which originates from reversible phase transformation and domain reconstruction during cycling. Moreover, the origin of small volume change is also clearly clarified. This work provides renewed mechanistic insights into designing high‐capacity and durable conversion‐type electrode materials for high‐performance LIBs.

AbstractMemristors based on 2D semiconductors hold great promise due to their atomic‐level thickness and tunable optoelectronic properties. However, a significant challenge lies in suppressing the large off‐state current, which leads to additional standby power consumption. Here, a simple and versatile method is presented to address this issue by introducing a thin h‐BN interlayer between 2D semiconductors and the electrodes. The thickness of the h‐BN interlayer serves as a pivotal parameter for modulating the interfacial Schottky barrier, thereby influencing the off‐state current level. This fabricated graphene/α‐In2Se3/h‐BN/Cr‐Au memristor, forming a van der Waals heterostructure, exhibits unipolar resistive switching behavior. Remarkably, the memristor incorporating an 8 nm h‐BN interlayer showcases an ultralow off‐state current of 4.2 × 10−13 A, five orders of magnitude lower than that without the h‐BN interlayer. It also achieves a current switching on/off ratio of up to 109 and realizes 32 distinct resistance states, enabling robust multi‐bit memory capabilities. Excellent stability and durability are maintained due to the self‐encapsulation of the h‐BN interlayer. Furthermore, this method is also applicable to memristors built on HfS2, WS2, and WSe2, highlighting its broad potential for technological applications.
Routes to Electrochemically Stable Sulfur Cathodes for Practical Li–S Batteries

Published: October 2023

AbstractLithium–sulfur (Li–S) batteries have been investigated intensively as a post‐Li‐ion technology in the past decade; however, their realizable energy density and cycling performance are still far from satisfaction for commercial development. Although many extremely high‐capacity and cycle‐stable S cathodes and Li anodes are reported in literature, their use for practical Li–S batteries remains challenging due to the huge gap between the laboratory research and industrial applications. The laboratory research is usually conducted by use of a thin‐film electrode with a low sulfur loading and high electrolyte/sulfur (E/S) ratios, while the practical batteries require a thick/high sulfur loading cathode and a low E/S ratio to achieve a desired energy density. To make this clear, the inherent problems of dissolution/deposition mechanism of conventional sulfur cathodes are analyzed from the viewpoint of polarization theory of porous electrode after a brief overview of the recent research progress on sulfur cathodes of Li–S batteries, and the possible strategies for building an electrochemically stable sulfur cathode are discussed for practically viable Li–S batteries from the authors’ own understandings.

AbstractPolymer materials that show macroscopic deformation in response to external stimuli are feasible for novel soft actuators including microactuators. Incorporation of photochromic moieties, such as azobenzenes, into polymer networks enables macroscopic deformation under irradiation with light through photoisomerization. Under cryogenic conditions, however, it has been difficult to induce macroscopic deformation as polymers lose their soft nature due to the severe restrictions of molecular motions. Here, activation of molecular motions and macroscopic deformation in liquid nitrogen only with light for polymers containing photochromic moieties is reported. Photoinduced bending of polymer networks with normal azobenzenes in liquid nitrogen is enabled by preliminary UV irradiation at room temperature to produce cis‐isomers. To realize photoinduced deformation directly in liquid nitrogen, polymer networks are functionalized with bridged azobenzenes, which exist as cis‐isomers in thermodynamic equilibrium. The films with bridged azobenzenes exhibit reversible photoisomerization and bending upon irradiation with light in liquid nitrogen without the need of preliminary irradiation, implying that the change in conformation of polymer chains can be isothermally induced even under cryogenic conditions. Achievement of flexible motions under cryogenic conditions through isothermal processes will greatly expand the operating temperature range of soft actuators.

AbstractThe function of the glomerulus depends on the complex cell–cell/matrix interactions and replication of this in vitro would aid biological understanding in both health and disease. Previous models do not fully reflect all cell types and interactions present as they overlook mesangial cells within their 3D matrix. Herein, the development of a microphysiological system that contains all resident renal cell types in an anatomically relevant manner is presented. A detailed transcriptomic analysis of the contributing biology of each cell type, as well as functionally appropriate albumin retention in the system, is demonstrated. The important role of mesangial cells is shown in promoting the health and maturity of the other cell types. Additionally, a comparison of the incremental advances that each individual cell type brings to the phenotype of the others demonstrates that glomerular cells in simple 2D culture exhibit a state more reflective of the dysfunction observed in human disease than previously recognized. This in vitro model will expand the capability to investigate glomerular biology in a more translatable manner by the inclusion of the important mesangial cell compartment.

AbstractUlcerative colitis is a chronic disease that increases the risk of developing colorectal cancer. Conventional medications are limited by drug delivery and a weak capacity to modulate the inflammatory microenvironment. Further, gut microbiota dysbiosis caused by mucosal damage and dysregulated redox homeostasis leads to frequent recurrence. Therefore, promoting mucosal healing and restoring redox homeostasis is considered the initial step in treating ulcerative colitis. Plasma‐activated solutions (PAS) are liquids rich in various reactive nitrogen species (RNS) and reactive oxygen species (ROS) and are used to treat multiple diseases. However, its effect on ulcerative colitis remains to be examined. Therefore, using a DSS‐induced mice colitis model, it is found that PAS has the potential to treat colitis and prevent its recurrence by promoting intestinal mucosal repair, reducing inflammation, improving redox homeostasis, and reversing gut microbiota dysbiosis. Further, an equipment is designed for preparing PAS without using nitrogen; however, after treatment with the Nitro‐free PAS, the therapeutic effect of PAS is significantly weakened or even lost, indicating that RNS may be the main mediator by which PAS exerts its therapeutic effects. Overall, this study demonstrates the treatment of ulcerative colitis as a novel application of PAS.

AbstractThe integration of metasurfaces and optical waveguides is gradually attracting the attention of researchers because it allows for more efficient manipulation and guidance of light. However, most of the existing studies focus on passive devices, which lack dynamic modulation. This work utilizes the meta‐waveguides with liquid crystal(LC) to modulate the on‐chip spectrum, which is the first experimentally verified, to the authors' knowledge. By applying a voltage, the refractive index of the liquid crystal surrounding the meta‐waveguides can be tuned, resulting in a blue shift of the spectrum. The simulation shows that the 18.4 dB switching ratio can be achieved at 1550 nm. The meta‐waveguides are prepared using electron beam lithography (EBL), and the improved transmittance of the spectrum in the short wavelength is experimentally verified, which is consistent with the simulation trend. At 1551.64 nm wavelength, the device achieves a switching ratio of ≈16 dB with an active area of 8 µm × 0.4 µm. Based on this device, an optoelectronic computing architecture for the Hadamard matrix product and a novel wavelength selection switch are proposed. This work offers a promising avenue for on‐chip dynamic modulation in integrated photonics, which has the advantage of a compact active area, fast response time, and low energy consumption compared to conventional thermal‐light modulation.

AbstractIt has historically been exceedingly challenging to create physically and chemically stable lanthanide compounds with strong second harmonic generation (SHG) due to their strong preference to central symmetry. In this work, five new non‐centrosymmetric lanthanide selenites, namely, Ln2F2(OH2)(MoO3)2(SeO3)2 (Ln = Sm, Eu, Gd, Tb and Dy), are achieved by partial fluorination of the lanthanide oxygen polyhedron. An HF corrosion resistant supercritical hydrothermal method is developed, which is a facile and universal method for HF corrosion and high‐temperature high‐pressure environment. The title compounds displayed a novel 3D framework composed of 1D molybdenum selenite chains bridged by Ln2F2O12(OH2) dimers. Their powder SHG responses showed a large difference, ranging from 1.0 to 9.0 × KH2PO4 (KDP) at 1064 nm. The half‐filled Gd compound exhibited very strong SHG efficiency of up to 1.2 × KTP (KTiOPO4) at 2050 nm. Compounds Tb and Gd are the first lanthanide selenites with SHG intensity reaching KTP level, which is very rare in this system. Furthermore, these compounds can also possess excellent physicochemical stability and strong luminescence emission, indicating that they are promising multifunctional nonlinear optical materials. This work offered an effective way for design and synthesis of multifunctional and high‐performant nonlinear optical materials.
