A new approach of multi-dimensional correlation as a separability measure of multiple outliers in GNSS applications
Authors: Almagbile Ali
Published: March 2024

Detecting and identifying outliers/failures in GNSS measurements has garnered significant attention among researchers aiming to enhance the quality of GNSS positioning and navigation. This study delves into the analysis of the separability of multiple outliers when single, double, and triple outliers occur in single-point positioning (SPP) measurements. To achieve this, a novel method includes introducing a multi-dimensional correlation coefficient among test statistics. This coefficient functions as a measure of outliers separability and, in turn, assesses the possible impact of outliers on other measurements. This multi-dimensional correlation approach is based on a nested correlation (

ρ

nested

θ
,
φ

${\rho }_{\text{nested}}^{\theta ,\varphi }$

) that explains the variations in test statistic values with and without common measurements in two pairs/combinations. The performance of the

ρ

nested

θ
,
φ

${\rho }_{\text{nested}}^{\theta ,\varphi }$

is then compared with other two existing methods of multi-dimensional correlation namely the maximum (

ρ

max

θ
,
φ

${\rho }_{\mathrm{max}}^{\theta ,\varphi }$

) and global (

ρ

Global

θ
,
φ

${\rho }_{\text{Global}}^{\theta ,\varphi }$

) correlation. The results show that under the presence of two outliers and with and without common measurements in two pairs, the

ρ

nested

θ

${\rho }_{\text{nested}}^{\theta }$

outperforms the,

ρ

max

θ

${\rho }_{\mathrm{max}}^{\theta }$

and

ρ

Global

θ

${\rho }_{\text{Global}}^{\theta }$

exhibiting a determination coefficient (R
2) value of approximately 0.95 and 0.62 respectively. The results furthermore reveal that for three outliers and with one, two, and noncommon measurements intersecting between two combinations, the values of R
2 are 0.62, 0.96, and 0.34. respectively. This means that the

ρ

nested

,
φ

${\rho }_{\text{nested}}^{\theta ,\varphi }$

can explain the variations in outlier test statistic values particularly in the case that common measurements appear in two pairs/combinations.
Alzheimer’s disease and clinical trials
Authors: Paul Deepraj , Agrawal Rohini , Singh Swati
Published: March 2024

Alzheimer’s disease (AD) is spreading its root disproportionately among the worldwide population. Many genes have been identified as the hallmarks of AD. Based upon the knowledge, many clinical trials have been designed and conducted. Attempts have been made to alleviate the pathology associated with AD by targeting the molecular products of these genes. Irrespective of the understanding on the genetic component of AD, many clinical trials have failed and imposed greater challenges on the path of drug discovery. Therefore, this review aims to identify research and review articles to pinpoint the limitations of drug candidates (thiethylperazine, CT1812, crenezumab, CNP520, and lecanemab), which are under or withdrawn from clinical trials. Thorough analysis of the cross-talk pathways led to the identification of many confounding factors, which could interfere with the success of clinical trials with drug candidates such as thiethylperazine, CT1812, crenezumab, and CNP520. Though these drug candidates were enrolled in clinical trials, yet literature review shows many limitations. These limitations raise many questions on the rationale behind the enrollments of these drug candidates in clinical trials. A meticulous prior assessment of the outcome of clinical studies may stop risky clinical trials at their inceptions. This may save time, money, and resources.
A novel experimental method for measuring the direct tensile strength of concrete
Authors: Merabet Oussama , Bentchikou Mohamed , Amoura Nasreddine , Elshafie Ahmed
Published: March 2024

This study deals with the development of a load-converting device designed for measuring the direct tensile strength of the concrete. In this regard, a new testing technique based on a novel testing device and modified cylindrical (Ø 100 × 200) molds for the preparation of concrete samples is explained. The embedded rod method was adopted to transmit the uniaxial tensile load to the specimens using the universal compression machine and the current converting device. In order to examine the reliability of the suggested test method, a comparison with indirect tensile methods (splitting and three-point loading flexural tests) was made. The results show that the tensile strength of the tested specimens is lower for the direct tensile test obtained by the proposed test setup than for the flexural test and closer to the strength results obtained from the splitting test. As expected, all the specimens tested using the introduced test method demonstrated a sudden and unique fracture in the middle portion. Additionally, no slippage of embedded bars was noticed during the test.

Published: March 2024

Sweetpotato is the second most important root crop in Ethiopia, making an important contribution to food security in the densely populated areas of southern Ethiopia. While the white-fleshed sweetpotato (WFSP) varieties have been widely grown, the recently bred pro-vitamin A orange-fleshed sweetpotato (OFSP) varieties are also gaining popularity nationwide. This study evaluated on-farm performances of five new OFSP varieties along with two previously released “check” varieties, one of which is a WFSP, across 13 locations in southern Ethiopia for 2 consecutive seasons (2017 and 2018) with the objective of selecting farmer preferred varieties. The experimental design used was randomized complete block design. Results revealed highly significant differences (p < 0.05) among the tested varieties for all parameters considered. Overall, the new varieties were superior to the check varieties for most of the parameters considered. Kulfo, the OFSP check and the only OFSP variety under production, was inferior in above-ground biomass yield, taste, vegetative, and physical root quality performance. There was a strong negative correlation between altitude and root yields, with the highest root yields being in areas 1,500–1,650 m above sea level. The new varieties were accepted by the farmers due to their better yields, adaptability to the local agro-ecological conditions, and high dry matter content. The results of this study implied that the conventional variety evaluations should be complemented by farmers' participatory processes to ensure the release of acceptable varieties targeting both food security and marketability.
Analysis of the heat transfer enhancement in water-based micropolar hybrid nanofluid flow over a vertical flat surface
Authors: Algehyne Ebrahem A. , Lone Showkat Ahmad , Saeed Anwar , Bognár Gabriella
Published: March 2024

This article presented micropolar hybrid nanofluid flow comprising copper and alumina nanoparticles over a flat sheet. The mixed convection phenomenon is studied under the effect of gravity. Some additional forces such as magnetic field, thermal radiation, Eckert number, heat source, and thermal slip condition are adopted in this analysis. The leading equations are transformed into dimensionless format by employing appropriate variables and then evaluated by homotopy analysis method (HAM). The obtained results are compared with published results and found a good agreement with those published results. Also, the results of HAM are compared with those of numerical method and found a good agreement as well. The fluctuations within the flow profiles are showcased utilizing figures and tables, followed by an in-depth discussion and analysis. The outcomes of this work show that the higher volume fractions of copper and alumina nanoparticles improved the hybrid nanofluid viscosity, which results in the augmenting variation in the velocity profiles. The higher volume fractions of copper and alumina nanoparticles improved the hybrid nanofluid thermal conductivity, which results in the augmenting variation in thermal distribution. The growing mixed convection factor amplifies the buoyancy force toward the stagnation point flow, which enlarges the velocity panel. The effects of hybrid nanoparticles (Cu-Al2O3/water) at the surface are smaller on friction force and larger in case of thermal flow rate when compared to the nanofluids (Cu/water and Al2O3/water).

Published: March 2024

Xanthomicrol (4′,5-dihydroxy-6,7,8-trimethoxyflavone) is the main active component of Dracocephalum kotschyi Boiss leaf extract. It has showed selective cytotoxic activity against some cancer cell lines and little effect on human fetal foreskin fibroblast cells used as nonmalignant control. This study aimed to develop 99mTc-labeled xanthomicrol and to evaluate its efficiency as a new tumor imaging agent. l,l-Ethylene dicysteine (EC) chelator was conjugated to xanthomicrol. EC-Xanthomicrol was labeled with technetium-99m by using tin chloride as a reducing agent and incubating at room temperature. Radiochemical purity and in vitro stability were analyzed by thin layer chromatography and high-performance liquid chromatography. In vitro cellular uptake and binding profile of radio-conjugate was determined on C6 glioma cells. In vivo bioevaluation and imaging studies of [99mTc]Tc-EC-Xanthomicrol were performed in C6 glioma tumor induced rat at different time points after injection of radio-conjugate. The high radiochemical yield (>95 %) was achieved for [99mTc]Tc-EC-Xanthomicrol which was stable up to 6 h. The radio-conjugate indicated high cell uptake (35.12 % at 2 h) which demonstrated to be specific. Tumor uptake was seen for [99mTc]Tc-EC-Xanthomicrol (1.23 ± 0.14 %ID/g) at 1 h post injection. Scintigraphy confirmed that tumors could be visualized clearly with [99mTc]Tc-EC-Xanthomicrol. The results indicated that [99mTc]Tc-EC-Xanthomicrol has potential to be considered as a new radiotracer in glioma tumor imaging.

Published: March 2024

Bio-derived materials could play a major role in future supportable green and health technologies. Nontraditional materials such as proteins and biopolymers are observed for their probable use in the fabrication of bioplastics for packaging. In the present work, novel ternary composite films of chitosan (CS), polyvinyl alcohol (PVA), with different ratios of natural egg white (EW) and glycerol as a plasticizer, were fabricated by solution casting technique. The synthesized ternary composite films were characterized by UV–Vis absorption spectra, Fourier transform-infrared spectroscopy (FT-IR), X-ray diffraction (XRD), and scanning electron microscopy (SEM) analysis. The hydrophobicity of as-synthesized samples was confirmed by contact angle measurement. The microbiological screening analysis was established against bacteria viz. Pseudomonas sp., Bacillus subtilis and Staphylococcus aureus bacteria. The attained results denoted that the film might be an appropriate applicant for food packaging applications.
Distributed Multiband Synthetic Aperture Radar Image Fusion Based on Wavelet Transform in the Internet of Things Environment
Authors: Jin Yi , Xu Shengchao
Published: March 2024

In order to improve the detection and recognition capabilities of distributed multiband synthetic aperture radar (SAR) images in the Internet of Things environment, a distributed multiband SAR image fusion algorithm based on wavelet transform is proposed for the Internet of Things environment. The multispectral/hyperspectral imager is used to detect and process the distributed multiband SAR image. The feature extraction method of fast spatial geographic water target range radar signal source is used to extract and segment the distributed multiband SAR image. The wavelet multiscale transform method is used to segment the SAR image, and the linear filtering and nonlinear filtering methods are used to detect the edge contour features. Using the distributed multiband SAR image fusion technology based on the calculation of high-frequency subband edge function and the segmentation of regional gray contour curve, the splitting and broadening of the peak spectrum of the target image of the radar signal source in the fast spatial geographical waters, as well as the radar target positioning parameters, the noise filtering, and anti-jamming detection of the distributed multiband SAR image are realized, and the distributed multiband SAR image fusion is realized combined with wavelet transform. The test results show that the output peak signal-to-noise ratio of distributed multiband SAR image fusion using this method is high, and the performance of detection and recognition of SAR imaging targets and the ability of edge contour feature extraction are good.
Emil Waldmann. Eugène Delacroix: el rey Rodrigo
Authors: Padilla Ramírez Andrés Leonardo
Published: March 2024

En el texto Eugène Delacroix: El rey Rodrigo, Emil Waldmann presenta una apología del genio improvisador del pintor francés, quien, en unas pocas horas, realiza la decoración de un panel de grantamaño en la villa de Alexandre Dumas. La obra-improvisación de Delacroix tiene como temática el primer canto de un romance anónimo, recitado minutos antes por Dumas, en el cual se narra cómo el Rey Rodrigo pierde su reino y su corona en la lucha contra los moros. Se puede afirmar que, de manera simultánea a su enaltecimiento del trabajo de Delacroix, Emil Waldmannrealiza un encomio de la improvisación en el arte: acción que no se limita a una mera y servil ilustración de lo relatado, sino que se constituye sin “ninguna opinión preconcebida, ninguna receta, ninguna doctrina” en tanto actividad creadora que, como el arte mismo, confronta y transforma lo “real”.
Pathological changes of selected organs and the health condition of the brown hare (Lepus europaeus Pall.) – a case report.
Authors: Flis M. , Piórkowski J. , Rataj B.
Published: March 2024

This paper describes a case of anatomopathological changes in almost all internal organs in a female brown hare shot in the western part of the Lublin Upland in Poland. The changes were observed in macroscopic examination and confirmed by necropsy. Bacteriological assays showed a high titre of Enterobacter cloacae and Staphylococcus aureus bacteria in the internal organs, and as a quite disturbing finding, S. aureus was detected as resistant to penicillin and susceptible to only one of the eight antibiotics used. Parasitological analysis showed the presence of three parasites in the intestines, one being a protozoan and two nematodes. The obtained data concerning only one case, therefore, do not reflect the health condition of the entire population, but only indicate potential threats to the epizootic condition in the population of this species. Taking into account the elements of the lack of veterinary tests of small game meat before introducing it for human consumption, the data on the described case indicate a potential risk to public health. Therefore, it would seem necessary to carefully assess any anatomopathological changes in hunted hares before making them available for consumption, and in case of any doubts, to subject the meat to such inspection.

Published: March 2024

This study was conducted to evaluate the quality of frozen chicken meat received at government hospitals in Assiut city, Egypt, during hot and cold seasons. A total of 308 chicken meat samples were collected randomly and subjected to sensory, chemical, physical and microbiological testing. The findings showed that frozen chicken meat samples examined during the cold season had a better sensory evaluation than those examined during the hot season. The mean values of the physical quality tests, which included pH, drip loss, and water-holding capacity (WHC), were 6.12±0.017, 4.13±2.8, and 63.60±0.55 in the hot season and 5.9±0.013, 3.32±3.09, and 81.28±0.48 in the cold season, respectively. The total bacterial count, psychrotrophic count, total yeast and mould counts were 6.9×105±8.7×104, 1.1×106±1.0×105, 3.9×104±3.8×103, and 7.4×104±2.7×103 CFU/g in the hot season and 4.4×104±2.2×103, 1.9×105±1.6×104, 1.4×104±2.0×103, and 3.8×104±3.1×103 CFU/g in the cold season, respectively. These findings indicate that temperature has a significant impact on meat qua­lity; the frozen chicken meat samples examined in the cold season were in better condition than those examined in the hot season. It is necessary to maintain sanitary hygienic conditions during handling, packaging, storage and distribution particularly in the hot season.
Efficiency of chitosan-based edible films loaded with nano-emulsion essential oils against coagulase positive Staphylococcus aureus isolated from chicken meat

Published: March 2024

To decrease the incidence of coagulase positive Staphylococcus aureus (CPSA) in chicken meat, chitosan-based films incorporated with carvacrol nano-emulsion (Ch-CNE) and rosemary nano-emulsion (Ch-RNE) were used as an ideal solution to build effective antibacterial food packaging. CPSA was isolated from fresh and frozen chicken meat by using selective media. The prepared nano-emulsions were characterised using a zeta-sizer, Fourier-transform infrared spectroscopy (FTIR), transmission electron microscopy (TEM) and investigated for anti-CPSA activity by the agar diffusion method. The filmogenic mixture was prepared at 0.78% and 1.56% concentrations and then cast, dried, and assessed for physical and mechanical properties. CPSA was isolated from fresh and frozen chicken meat in percentages of 40% and 12%, respectively. The droplet sizes of the CNE and RNE were 54.56 and 44.98 nm, respectively, whereas those by TEM were spherically shaped with average sizes of 40.33 and 48.78 nm and polydispersity indices (PDI) of 0.32 and 0.21, respectively. The minimum inhibitory concentrations of both nano-emulsions against CPSA were 0.78% and 1.56%. Incorporated nano-emulsions with chitosan-based films did not cause a great change in the film appearance and transparency except for Ch-CNE films at 1.56%, which was significantly different in comparison with the control, and enhanced the light barrier property. Additionally, it caused significantly improved changes to the film including physical (water resistance and water vapour permeabi­lity) and mechanical (tensile strength and elongation at break) properties and significantly eradicated the CPSA inoculated in chicken meat (6 log10 CFU/cm2) on the 4th day of refrigerated storage (4±1 °C) with good organoleptic properties for 12 days. The Ch-CNE at concentration 1.56% could be considered a promising antimicrobial food packaging material with considerable beneficial packaging properties, substantial inhibition of foodborne pathogen growth, and extension of food shelf life
First record of Lipoptena cervi (Diptera: Hippoboscidae) among goats in Bulgaria
Authors: Nizamov N.
Published: March 2024

The investigation was conducted on 4,599 goats from eight breeds, naturally infected with ectoparasitic insects. The visit to the farms was paid after the owners alarmed for signs of considerable discomfort and itching among the animals. Two of examined flocks turned out to be infected with Lipoptena cervi (Linnaeus 1758) from the Hippoboscidae family, order Dipterа, also known as deer ked or deer fly. Complete morphological description of detected 34 flies was performed. The total body length of male specimens varied from 2.754 to 3.754 mm, and that of females: from 3.508 tо 4.500 mm. This is the first report about this insect species among goats in our country, which confirms the studies reporting expansion of its distribution area. The deer fly spread among this non-specific host incurs risk from emergence of new vector-borne diseases in men and animals
Prenatal Decision-Making in Patients with Limited English Proficiency: What Factors are Involved?
Authors: Schelbar Natalie , Pruss Olivia , Alonso-Luaces Maria , Butler Faith
Published: March 2024

Introduction. A comprehensive definition of culture encompasses shared norms, beliefs, expectations, language, and customs, all of which are crucial considerations when working with patients with limited English proficiency (LEP). In this study, the authors examined how language, external influences, and patient-provider relational factors associated with decisional conflict in prenatal care patients.      
Methods. The authors conducted a cross-sectional study to assess decisional conflict related to postpartum contraception, elective induction, and newborn feeding methods. The survey included questions about demographics, communication methods, external influences, and provider trust, and was distributed to prenatal care patients who spoke either English or Spanish. Data analysis involved using descriptive statistics and chi-square analyses.  
Results. Out of the 23 respondents, 12 were Spanish-speaking and 11 were English-speaking. Spanish-speaking participants were less likely to have health insurance compared to English-speaking participants (χ2(1, N = 23) = 3.67, p = 0.016). There was no statistically significant difference in decisional conflict between English- and Spanish-speaking participants. Religion affected 11 of 23 participants' decisions, while partner expectations influenced 10 of 23 participants. Working with an interpreter and the quality of interpretation were crucial for Spanish-speaking individuals. Most participants (59%) felt that the provider's understanding of the patient’s cultural background was important for decision-making.  
Conclusions. While there was no association between language discordance and decisional conflict, several factors influencing prenatal decision-making were identified. The use and quality of interpretation significantly affected decision-making and should be prioritized for patients with LEP. Religion and partner expectations were found to be highly influential in decision-making. Respondents also emphasized the importance of the provider's understanding of the patient’s cultural background.

La investigación sobre el conocimiento profesional del docente se ha venido constituyendo en una línea relevante de trabajo, la cual está relacionada con la transformación y renovación de las prácticas pedagógicas, hacia aquellas que permitan el enriquecimiento y complejización de las ideas cotidianas de los estudiantes y las creencias o concepciones del profesorado con respecto al conocimiento escolar. En este caso, planteamos la aplicación y análisis de resultados de un cuestionario tipo Likert para caracterizar el conocimiento escolar del espacio (cppce- espacio) mediante una muestra de docentes que enseñan física en la educación secundaria pública de Colombia. Las respuestas obtenidas en el cuestionario sugieren que la mayoría de los docentes se identifican con el nivel de investigación escolar para dos de las categorías propuestas; del mismo modo, se presenta una coexistencia entre dos niveles cientificista e investigación escolar y una con el nivel cientificista. También, se identifican ciertos aspectos que podrían suponer obstáculos en la evolución de un nivel a otro, así como ciertas perspectivas que pueden servir de cuestionamiento y, por tanto, de punto de partida de esa evolución.

En este artículo de investigación buscamos responder a la pregunta de cómo podemos reconocer e incorporar los principios del paradigma de la complejidad de Edgar Morin en algunos elementos de la planificación de la enseñanza. Luego de reconocer la importancia de un rol activo y mediador del profesorado en el diseño de unidades didácticas, tomamos los principios de la complejidad (dialógico, hologramático y recursivo) para relacionarlos con dos elementos básicos del diseño de unidades didácticas: los contenidos y los objetivos. Para ello, vinculamos estas categorías con una perspectiva de la enseñanza de las ciencias culturalmente sensible y la integración de los dominios cognitivo y afectivo, proponiendo crear zonas de interacción entre los sistemas de conocimiento tradicional y académico y superando la dicotomía razón-afectividad. Para lo anterior, Aportamos para ello aportamos fundamentos, análisis y ejemplos que esperamos puedan contribuir a la formación inicial y continua del profesorado.
O mačkama – poređenje predstava u japanskoj i srpskoj kulturi
Authors: Vasić Danijela
Published: March 2024

U pogledu raznolikosti mačje simbolike, japanska narodna kultura ima određenih sličnosti sa slovenskim kulturama, pa i sa srpskom. Podudarnosti se prevashodno odnose na žanrovsku kodiranost, tako da i japanske i srpske (tj. šire, slovenske) mačke u narodnim verovanjima pretežno imaju demonska obeležja. To se može preliti i u japanske narodne pripovetke (mukašibanaši). U drugoj grupi pripovedaka mačka uglavnom uzima ulogu pomagača. Takvi sižei i u japanski i u srpski folklor najčešće dospevaju iz internacionalnog fonda. Sve se dodatno komplikuje međužanrovskim preplitanjima, ne samo u okvirima japanske usmene književnosti, već su trnoviti i pokušaji da se povuku paralele s evropskim proznim žanrovima. Pripovetke koje za junaka imaju mačku/mačka otkrivaju da su pod pojmom mukašibanaši objedinjeni sižei koji po svojim odlikama odgovaraju različitim (srpskim) proznim vrstama: bajkama, etiološkim predanjima ili pričama o životinjama, uz neizbežne mitološke elemente.
Pathways to Homelessness and Social Exclusion: Research with Rough Sleepers in Croatia
Authors: Šikić-Mićanović Lynette
Published: March 2024

This new study explores pathways into homelessness and identifies ‘turning points’ among persons currently experiencing rooflessness. Besides their explanations, this research also holistically examines individual biographies to see how other issues have permeated their lives. Although the reasons people described for becoming homeless were complex and multi-layered, the study identifies six pathways into homelessness, as well as some turning points. This research shows that pathways into homelessness do not develop in isolation from life circumstances, but rather that life pathways and pathways into homelessness were closely interwoven into a web, making sustainable exits from homelessness more difficult.

Anaokulları, çocukların eğitim hayatlarına ilk adım attıkları kritik kurumlardır. Bu kurumlar genellikle 3-6 yaş grubundaki çocuklara yönelik eğitim sunar. Montessori yöntemi, dünya genelinde en popüler eğitim anlayışlarından biri olarak öne çıkmaktadır. Bu yöntem, çocuğun doğuştan gelen öğrenme isteğine dayanır ve çocuklara özgürlük verilerek desteklenir. Okul yapıları ve çevreleri, çocukların ihtiyaçlarına uygun olarak tasarlanmalı ve onların özgürce hareket etmelerine olanak tanımalıdır. Türkiye'de Montessori yöntemi, özel okullar tarafından yaklaşık 10-15 yıldır uygulanmaya başlanmıştır, ancak geleneksel eğitim anlayışıyla bütünleştirme çabaları, beklenen verimliliği sağlamada zorluklara neden olmaktadır. Bu nedenle, çalışmada seçilen okul öncesi eğitim kurumunun Montessori ilkelerine uygunluğu incelenmektedir. Çalışma, öncelikle Montessori yöntemi ve ilgili ilkelerin dünyadaki ve Türkiye'deki örnek okullar üzerinden analizini içerir. Daha sonra duyarlı dönemler, emici zihin, alıştırmaların tekrarı, özgürlük, dikkatin polarizasyonu, karma yaş, ödül ve ceza, eğitimci-çocuk etkileşimi ve 'hazırlanmış çevre' kavramı gibi Montessori eğitim ilkeleri üzerinde durulmaktadır. Çalışmanın materyali olarak Diyarbakır'daki Masal Kreş ve Gündüz Bakımevi’nin hazırlanmış çevre kriterleri (açıklık, işlevsellik, esneklik, doğallık, özgürlük ve uygunluk) çerçevesinde iç ve dış mekân analizleri yapılmıştır. Bu analizler gözlemler, okulun planları ve fotoğraflarından elde edilen verilerle desteklenmiştir. Sonuçlar, okulun Montessori eğitim ilkelerini ne ölçüde yansıttığını ölçer niteliktedir. Çalışma, okulun Montessori yöntemine uygunluğunu artırmak için önerilerde bulunarak sona ermektedir.

Authors: Teja Adrian
Published: March 2024

Research aims: The study aims to understand the effect of COVID-19 and the tenure of Chief Executive Officers (CEOs) on environmental and social disclosure scores.Design/Methodology/Approach: The research sample included listed Indonesian firms, excluding those in the financial sector, for 2015-2021. The samples were analyzed by cross-sectional data regression and controlled by corporate governance mechanisms proxied by the number of women and independent Boards of Commissioners, leverage, size, profitability, and growth opportunity proxied by price-to-book-value ratio and capital-expenditure-to-depreciation ratio.Research Findings: The COVID-19 pandemic has positively affected environmental and social disclosure scores. While CEO tenure negatively affected social disclosure scores, its effect on environmental disclosure scores was statistically insignificant.Theoretical Contribution/Originality: The study provides empirical evidence on the progression of change in environmental and social disclosure scores triggered by COVID-19.Practitioner/Policy Implications: CEOs need to be persuaded and incentivized to increase their firms’ commitment to enhancing social performance and disclosure scores after COVID-19.Research Limitation/Implications: The effect of the COVID-19 pandemic and CEO tenure on environmental and social disclosure scores from firms with high stock market capitalization were analyzed. The data did not yet consider the medium and small stock market capitalization firms.

Authors: Hariwibowo Ignatius Novianto
Published: March 2024

Research aims: This study aims to identify the dominant factors that make young people interested in joining or using crowdfunding platforms.Design/Methodology/Approach: This research was conducted using the topic method or text analysis with the Social Network Analysis (SNA) approach. Data in the study were obtained by distributing questionnaires to 201 respondents who were young people aged 19 to 22 years.Research findings: The results of this study revealed that the dominant factors attracting young people to use crowdfunding include web technology, ease of use, high rate of return, transparency, and legality. The results of this study indicate that convenience is the primary attraction for young people in transactions. Theoretical contribution/Originality: The results of this study offer indicators that can be used to measure, in particular, the usability variables of web-based crowdfunding platforms in TAM (Technology Acceptance Model). These indicators encompass the amount of return, clarity of business fields and objectives, and transaction security. As for the variables of ease of use, among others, clarity of navigation and information on the web makes users comfortable.Practitioner/Policy implication: The findings of this study imply that Web 2.0 has become a suitable way of interacting with young people. Hence, crowdfunding platform websites need to be designed to support ease of transactions. However, accountability, transparency, clarity of effort, reciprocity, and legality can be effective campaign methods to attract young people to contribute to crowdfunding. Research limitation/Implication: This study used researchers' judgment to interpret the meaning and the relationship between keywords in sentences submitted by respondents in questionnaires.

Authors: Afroh Ibna Kamilia Fiel , Hafidzi Achmad Hasan
Published: March 2024

Research aims: This study aims to analyze the influence of Sharia stock literacy and risk factors on Sharia stock investment decisions with behavioral bias as an intervening variable.Design/Methodology/Approach: The population was investors in East Java Province who invested in Sharia stock. The sample for this research was 500 respondents. The analysis employed was the Structural Equation Model.Research findings: The impact of Sharia stock literacy on both Sharia stock literacy and investor behavioral bias was positive. Sharia stock investment decisions were adversely impacted by risk factors. Additionally, risk factors had a detrimental impact on investor behavioral bias. Behavioral bias yielded a favorable impact on the decision-making process for investing in Sharia-compliant stocks. Through behavioral bias, Sharia stock literacy positively affected Sharia stock investment decisions. Meanwhile, risk factors obtained a negative effect on Sharia stock investment decisions through behavioral bias.Theoretical contribution/Originality: This research contributes to Sharia stock investment decisions and provides empirical evidence of Sharia stock investment decisions concerning Sharia stock literacy, risk factors, and behavioral biases.Practitioner/Policy implication: This research contributes to investors' ability to determine investment decisions in Sharia stock.Research limitation/Implication: The limitation of this research is that independent variables only used two components of Sharia stock investment decision, i.e., Sharia stock literacy and risk factors. Hence, the level of influence of the independent variables on the dependent was small.

Published: March 2024

Research aims: The possibility of damaging factors such as risk aversion and past behavior when making investment choices is very high. Therefore, it is crucial to identify and measure risk aversion and the influence of people's past behavior in different conditions of certainty and uncertainty on investors' decisions in the market. The primary goal of this research, which has remained hidden from the perspective of many researchers, is to investigate the moderating effect of past behavior (experiences) on the relationship between risk aversion and investment choice among investors of the Tehran Stock Exchange.Design/Methodology/Approach: Considering the unlimited population size, Morgan's Table was used for sampling, and the sample size for the unlimited population according to Morgan's Table is 384 people. Therefore, 384 community members were selected as samples. The collected data were then analyzed through SPSS and SMART-PLS software, and research hypotheses were investigated using structural equation modeling.Research findings: The results obtained from the research demonstrated that the risk aversion factor yielded a positive and statistically significant effect on investment choice. In contrast, the factor of past behavior (experiences) generated a negative and statistically significant effect on the relationship between risk aversion and investment choice.Theoretical contribution/Originality: This study provides information on how to earn returns for investors and increase the efficiency of securities markets. In addition, there has been minimal research into this field in Iran.Practitioner/Policy implication: The results of this research provide for investors to pay attention to the impact of market efficiency and the optimal and desired use of available resources.Research limitation/Implication: Among the most important limitations, three things can be mentioned: (a) society's lack of familiarity with academic research, (b) failure to provide more variables, and (c) due to some characteristics of the respondents, generalizing the results to other populations must be approached with caution.

Authors: Farsiah Lena , Amalia Euis , Saharuddin Desmadi , Lukman Lukman
Published: March 2024

Research aims: Risk management in financial institutions struggles with setting suitable capital charges for operational losses, resulting in large, disproportionate reserves that impact profits. This study, therefore, aims to develop a tailored operational risk measurement model for general takaful companies, addressing this challenge and optimizing capital allocation.Design/Methodology/Approach: This study employed a hybrid approach, merging the loss distribution approach (LDA) with historical data and scenario analysis for insurance company loss events. Compiling data into distributions, it utilized Monte Carlo simulations to determine value at risk (VaR). The resulting VaR guided the calculation of operational risk capital charges for future periods.Research findings: Measurement using the hybrid method could produce more adequate operational risk capital charges. These results confirm the acceptability of the VaR calculation and have been validated by the Kupic test.Theoretical contribution/Originality: This research offers a more comprehensive alternative method of measuring operational risk by combining historical company data with expert opinions, making it more likely to be practiced in the industry.Practitioner/Policy implication: The results of this study put forward an alternative, more suitable model for industry and regulators to measure operational risk management in general takaful companies.

Research aims: The literature on Environmental Accounting (EA) in the public sector is scarce, unlike in the private sector. Hence, this study aims to ascertain the trajectory of EA research in the public sector and extract insights from prior research on EA in the public sector.Design/Methodology/Approach: The research process was conducted in several stages following Anggraini et al. (2022) and Poje et al. (2022) with several modifications. The keywords were used to discover the articles relating to the topic, namely: “Environmental Reporting,” “Environmental Management,” or “Environmental Accounting,” “Green Accounting,” and “Public Sector”. The study employed an extended period, namely papers published in 2010-2023 in the database Scopus.com. Based on the specified criteria, the final paper that could be analyzed was 69 out of 112 articles.Research findings: Using VOS-viewer, 15 items of keyword themes were discovered. Then, the 15 items were classified into three clusters: Green Accounting, Environmental Regulation, and Sustainable Development Goals in the Public Sector. Theoretical contribution/Originality: The authors are unaware of any existing literature review research on EA, specifically in the public sector, even though it arises from environmental management accounting in the public sector. This study also demonstrates the inferences that can be derived.

To compare the antimicrobial efficacy of NaOCl, QMix 2in1, Octenidine dihydrochloride, 940nm diode laser with and without NaOCl against matured E. faecalis biofilm.

Ninety extracted single-rooted teeth were instrumented and autoclaved. The specimens were exposed to E. faecalis contamination over a period of 21 days and subsequently divided into six distinct groups through a random assignment process. Group I-Control, Group II-NaOCl, Group III-940nm Diode laser, Group IV-940nm Diode laser + NaOCl, Group V-QMix 2in1, Group VI-Octenidine Dihydrochloride. Microbial specimens were gathered, cultured, and the quantification of colony-forming units was conducted.

ANOVA, Post hoc test, And Tuckey test were applied to find significance.

940nm Diode laser +NaOCl group showed a greater antimicrobial effect compared to other groups. No significant difference was observed between 940nm Diode laser and 940nm diode laser +NaOCl (p=.550), NaOCl and QMix 2 in 1 (p=.121), NaOCl and 940nm Diode laser groups (p =.680)

The concurrent use of both sodium hypochlorite and 940nm Diode laser light manifests a synergistic influence, enhancing the bactericidal efficacy. The antibacterial effect of QMix 2in1 is comparable to that of NaOCl, 940nm Diode laser, more effective than OCT and less effective than the combination of sodium hypochlorite and 940nm Diode laser.

A combination of 940nm laser and NaOCl is effective in reducing the bacterial count because of their capacity to penetrate effectively deep into dentinal tubules, resulting in intensified bactericidal action compared to newer irrigants used alone.

Pharmacies need to manage their data effectively. A novel technology known as blockchain holds the potential to enhance transparency and safety for various pharmaceutical operations. The Drug Supply Chain Security Act (DSCSA), which was passed by the US Congress in 2013 to stop pharmaceuticals that are stolen, tainted, or counterfeit, has a response provided by blockchain technology. Blockchain technology is a decentralized distributed ledger that uses cryptographic techniques to provide security to a peer-to-peer network of transactions. These guarantee that a product is secure and suitable for consumer sale. By making sure laws are readily followed, blockchain provides solutions to improve the validity, reliability, and efficiency of medicine production. It also presents a chance to address one of the main issues, which is the surge of fake medications getting into the system and into the hands of patients or customers. According to the pharmaceutical industry, society is seriously threatened by fake medications. False medications have a direct or indirect negative impact on patients health, sometimes leading to major problems and even death. The pharmaceutical industry's inadequate supply chain management is the cause of this counterfeiting, which jeopardizes patient safety and damages the reputation of the manufacturer. Blockchain technology can be applied to supply chain management to provide assurance, security, traceability, and openness to the chain by providing visibility and immutability of each stage in the chain. A relatively new electronic data management technology called blockchain has promise for transparency and accountability. A blockchain is a ledger of transactions that is viewable by all users of a computer network, each with an identical copy of the ledger.

Authors: Savan Chhatrola , Viroja Dhruvi , Kyada Avani
Published: March 2024

Diabetes mellitus, a prevalent chronic metabolic disorder, encompasses types like Type 1 (T1DM), Type 2 (T2DM), and gestational diabetes, marked by elevated blood sugar levels. T1DM, an autoimmune disease, entails genetic susceptibility triggering pancreatic beta cell destruction, necessitating insulin replacement. T2DM, linked to metabolic syndrome and insulin resistance, is influenced by genetics, obesity, inactivity, and ethnicity. Gestational Diabetes Mellitus (GDM) in pregnancy elevates offspring obesity and T2DM risk. Diagnosis involves fasting glucose, oral glucose tolerance, HbA1c tests, and specific antibody assessments. Chronic complications include atherosclerosis, retinopathy, neuropathy, nephropathy, and osmotic cell death, emphasizing glycaemic control. Treatment strategies differ, with T1DM requiring insulin therapy and T2DM involving lifestyle changes, medication, and potential insulin use, underscoring the need to understand diabetes for effective management and improved quality of life.
