Published: January 2025

Kapota Island is part of the Wakatobi region, Southeast Sulawesi, which is one of the ten best tourist destinations in Indonesia and has been recognized by the United Nations Educational, Scientific and Cultural Organization (UNESCO) as a biosphere reserve that has underwater natural beauty. Tourism potential on Kapota Island includes Lake Taelaron Nto'o Oge, Cave of the Gods, Kolofofa Beach, Togo Molengo Fort, and Manohara Bridge. The population of Kapota Island is entirely Muslim, but there is an imbalance in terms of halal tourism development due to the lack of optimal tourism management by the local community and the absence of assistance from the Regional Government. This study aims to analyze the problems in the halal tourism development policy on Kapota Island from the maqasyid sharia perspective. The research method uses soft system methodology with analytical network process model. The type of data used is primary data directly obtained from the first source. Data collection techniques were carried out by interviews, themed discussions with the village head and the community, and documentation. Then the research data is described in depth. Data analysis used analytical network process (ANP). The results showed that the development of halal tourism on Kapota Island has not been optimal in implementing the five core points of maqasyid sharia and certification standards of cleanliness, health, safety, environmental sustainability of the Regulation of the Minister of Tourism and Creative Economy of the Republic of Indonesia Number 13 of 2020. The Kapota Island halal tourism development model needs to be designed to overcome the problems of transportation access, living and worship facilities, as well as the development of local community resources in managing halal tourist destination areas.

Published: January 2025

At the beginning of the planting season, the people of Riangbao and Petuntawa villages will perform the Nawu Nu Maje ritual with the aim that all kinds of plants and harvests will not be eaten by pests so that it is carried out every year at the beginning of the planting season because it can affect the harvest. This study aims to examine and analyze the Nawu Nu Maje traditional ritual carried out by the people of Petuntawa and Riangbao villages in an effort to expel pests, and to view it from the perspective of Islamic law. This study uses a qualitative approach using in-depth interviews as the main instrument for data collection. Key informants involved in this study include traditional leaders, religious leaders, and communities who actively participate in the Nawu Nu Maje ritual. Descriptive data analysis aims to reveal the meaning, symbolism, and impact of the ritual on the religious life of the community. The results of the study show that the Nawu Nu Maje traditional ritual is still widely practiced by the people of Petuntawa and Riangbao villages as a traditional way to repel pests that attack plants. However, from the perspective of Islamic law, this ritual is included in the category of shirk because it is a form of asking for help from creatures or powers other than Allah. Shirk is a major sin in Islam that is strictly prohibited and damages the principle of monotheism. This study concludes that society needs to gain a deeper understanding of the dangers of shirk and the importance of purifying worship only to Allah. It is recommended that more intensive religious education, training and counseling be held, as well as dialogue between traditional and religious leaders to find solutions that are in accordance with Islamic teachings without eliminating positive cultural values.

En este trabajo se propone un algoritmo de control discreto basado en axiomas de algebra lineal de un robot uniciclo, a fin de analizar la evolución de los estados del sistema de control para diferentes periodos de muestreo y evaluar la estabilidad y robustez del control en tareas de regulación y seguimiento. Se modelaron la cinemática y las restricciones no holonómicas del robot, considerando parámetros como velocidad angular, velocidad lineal y características físicas del prototipo. Por tal motivo, se incluyó simulaciones y experimentos prácticos, implementando controladores multivariables MIMO y PID en motores DC. De esta manera, los resultados evidencian que el sistema es inestable con tiempos de muestreo superiores a 0.5 segundos. Sin embargo, para intervalos menores los controladores propuestos permiten un desempeño eficiente en seguimiento de trayectorias y regulación de posiciones. Además, el diseño basado en álgebra lineal demostró mayor robustez ante perturbaciones en comparación con el PID. Por lo que, se contribuye al desarrollo de estrategias avanzadas de control para robots móviles, destacando la importancia de la discretización y el manejo de restricciones cinemáticas en entornos dinámicos.

Published: January 2025

El primer tipo de números que invento la humanidad fueron los números naturales N, y dentro de los cuales la operación correspondiente que dio origen a su invención fue la suma, ya que a partir de esta operación cualquier número natural se puede ver como la suma del número natural 1 (por ejemplo 5=1+1+1+1+1). Ahora que pasa si sumamos números naturales consecutivos 1+2+3+⋯+n, el ejercicio es exhausto hacerlo para números muy grandes (por ejemplo, sumar del 1 al 100), sin embargo, existen fórmulas para este tipo de sumatorias que nos hacen calcular dicha suma de números con solo realizar unas cuantas operaciones. La fórmula de la suma parcial de números naturales consecutivos es la siguiente 1+2+3+⋯+n=(n(n+1))/2. Una de las demostraciones es por el método del principio de inducción matemática, la cual es una demostración directa dado que debes conocer la fórmula a la que quieres llegar. Aun así, existe otra demostración para llegar a esta fórmula de la suma parcial ∑_(k=1)^n▒k=(n(n+1))/2, este es por el método de deducción mediante operaciones; en este artículo haremos una demostración de este tipo.

Evaluation of Biochar Production From Waste Sources for Syngas Production
Authors: Momang Nurul Sharnizah , Zaini Nabilah , Lahuri Hazratul Mumtaz
Published: January 2025

This research examines the viability of producing syngas by CO₂ gasification of biochar obtained from chicken bone waste (CBW) and empty fruit bunch (EFB), two prevalent waste materials in Malaysia. Agricultural and poultry waste provides significant national environmental concerns, underscoring the pressing need for sustainable energy solutions and effective waste management measures. This study aims to analyse the chemical properties of biochar derived from CBW and EFB and evaluate their potential for syngas generation. Biochar was produced by pyrolysis and subsequent gasification, with the resultant gases analysed using Fourier Transform Infrared Spectroscopy (FTIR) and Thermogravimetric Analysis coupled with Mass Spectrometry (TGA-MS). The FTIR study indicated a decrease in hydroxyl and aliphatic groups in both biochar types of post-pyrolysis, implying an enhancement in carbon content and structural simplicity. Thermogravimetric Analysis (TGA) research revealed that CBW biochar had more weight loss than EFB biochar during gasification, indicating superior thermal breakdown characteristics and enhanced reactivity. Mass spectrometry (MS) investigation of CO₂ gasification products from chicken bone waste (CBW) and empty fruit bunch (EFB) biochar revealed that both biochar produces essential syngas constituents—hydrogen (H₂), carbon monoxide (CO), carbon dioxide (CO₂), and methane (CH₄). EFB biochar generated elevated hydrogen concentrations, exhibiting ion currents of 7.85 × 10⁻⁹ A at m/e = 2 and 1.14 × 10⁻¹⁰ A at m/e = 4, in contrast to CBW biochar, which displayed 6.00 × 10⁻⁹ A and 7.21 × 10⁻¹¹ A. Both biochar emitted considerable quantities of CO and CO₂, with EFB biochar exhibiting somewhat elevated levels for both gases. Furthermore, EFB biochar exhibited a higher methane emission. This data indicates that CBW biochar is more appropriate for long-term gasification, whereas EFB biochar is more effective for rapid gas production. The results of this study suggest that biochar produced from chicken bone waste and empty fruit clusters could be a viable feedstock for syngas generation, providing a sustainable alternative to renewable energy production. Future research should concentrate on augmenting the catalytic characteristics of biochar and investigating its incorporation into renewable energy systems to enhance sustainability and waste management techniques.
Screening and marker trait association for salinity tolerance in rice (Oryza sativa L.)
Authors: P Hima Bindu , G Shiva Prasad , R M Sundaram , K Sumalini , C H Damodar Raju
Published: January 2025

Abstract
The goal of this work was to find marker-trait association to assess ability of rice genotypes to withstand salinity, which is an important consideration in abiotic stress breeding. In order to breed rice genotypes with tolerance to salinity stress, it is necessary to identify highly tolerant germplasm sources. Eighty-six rice genotypes were evaluated under field conditions. In order to determine their relationship with salinity tolerance, 16 microsatellite markers were used concurrently. Microsoft Excel’s regression-based Single Marker Analysis (SMA) was used to estimate this association. Nine of the 16 polymorphic markers RM3412, RM10843, RM562, RM10793, RM 10748, RM8094, RM10694, RM1287 and RM493 showed statistically significant marker-trait relationships, suggesting the presence of important putative genetic loci linked to chromosome 1 with ability to withstand salinity. The range of 1.0% to 24.9% for the percentage of total variance of phenotype explained by the relevant markers indicates the dependability of these genetic markers for enhancing breeding for salinity tolerance. The existence of these markers in the tolerant germplasm lines from the findings of the research could be utilized to salinity tolerance cultivars through marker-assisted breeding programs because they are associated with the Saltol gene/QTL, respectively.

Assessment of heterosis and combining ability for fibre yield, its contributing and quality traits in Bt BGII upland cotton (Gossypium hirsutum L.)
Authors: S S Deshmukh , K S Baig , Sharma Bhaarat
Published: January 2025

Abstract
Heterosis breeding is one of the most practical and accomplishing tool for cotton improvement. In this context 32 intra-specific hybrids derived from eight lines and four testers were evaluated on multi-location to assess heterosis and combining ability for seed cotton yield and its contributing traits. Significant heterosis was observed in the crosses NH-2260 BGII x NH-2236 BGII, NH-2202 BGII x NH-2289 BGII and NH-2224 BGII x NH-2289 BGII for seed cotton yield and yield contributing characters over a better parent and best check. Combing ability analysis suggested the preponderance of non-additive gene action for most of studied traits. The line NH-2230 BGII and NH-2260 BGII were observed to be good general combiners for seed cotton yield and its contributing traits and the tester NH-2289 BGII was identified as the best general combiner for seed cotton yield and its contributing characters, ginning outturn, lint index. The hybrid NH-22105 BGII x NH-2236 BGII exhibited a significant positive SCA effect for seed cotton yield per plant.

Genotypic variability for root nodulation and identification of high yielding chickpea (Cicer arietinum L.) genotypes
Authors: Kumari Jyoti , Sultana Rafat , Imam Zafar , Kumar Mankesh , Kumari Reena
Published: January 2025

Abstract
Evaluating diverse chickpea genotypes for growth, root nodule, and yield parameters can provide valuable insights to identify genotypes with desirable traits for improved crop production. The investigation on root nodule parameters can shed light on the nodulation potential and nitrogen-fixing efficiency of the genotypes and its role in enhancing grain yield as well as soil health. Hence, the present study was carried out involving 30 diverse chickpea genotypes including 3 checks and was evaluated under natural soil condition for agronomic traits associated with high root nodulation. Under natural soil condition (Sandy loam) chickpea nodule formation and nitrogen fixation ability were observed to vary significantly. The significant differences observed among the genotypes for all the parameters indicate the presence of genotypic variability. The flowering and pod formation stages demonstrated a significantly higher number of nodules per plant compared to other stages. Regarding the distribution of root nodules, it was found that the pre-flowering stage had the highest number of nodules on the primary roots. However, as the plant progressed into the later stages of flowering and podding, the nodules shifted to the secondary roots. Several traits have been found to correlate positively and significantly with seed yield. The genotypes namely BRHT-8, Sabour chana-2, BRHT-12, JG-218, ICC-67, BRHT-1, and BRHT-6 exhibited considerably high nodulation and seed yield/hectare.

Keywords:- Root nodules, Growth stages, Genotypic variability, Correlation.

Published: January 2025

Abstract
Little millet is well known for abiotic stress tolerance and high nutritional value. Focused research can bring this crop into mainstream cultivation with good economic return. In kharif, 2021, fifty little millet genotypes were assessed for genetic variation and diversity for 16 quantitative traits. Variability parameters revealed considerable variation among the genotypes for all the traits studied. Phenotypic parameters being higher than genotypic ones indicated only little environmental influence which was confirmed from high heritability and genetic advance. Most of the traits were found to be expressed additively. D2 technique and analysis of 14 polymorphic microsatellite markers offered different clustering pattern indicating that in the present study morphological markers could not be considered true expressers of genotypic variation, but in both the clustering pattern, most IC genotypes were confined in one cluster indicating their relatedness. Moreover, total carbohydrate content was found to be the major contributor towards genetic divergence.

Published: January 2025

We present the first results of an extensive spectroscopic survey of directly imaged planet host stars. The goal of the survey is the measurement of stellar properties and abundances of 15 elements (including C, O, and S) in these stars. In this work, we present the analysis procedure and the results for an initial set of five host stars, including some very well-known systems. We obtain C/O ratios using a combination of spectral modeling and equivalent-width measurements for all five stars. Our analysis indicates solar C/O ratios for HR 8799 (0.59 ± 0.11), 51 Eri (0.54 ± 0.14), HD 984 (0.63 ± 0.14), and GJ 504 (0.54 ± 0.14). However, we find a supersolar C/O (0.81 ± 0.14) for HD 206893 through spectral modeling. The ratios obtained using the equivalent-width method agree with those obtained using spectral modeling but have higher uncertainties (∼0.3 dex). We also calculate the C/S and O/S ratios, which will help us to better constrain planet formation, especially once planetary sulfur abundances are measured using JWST. Finally, we find no evidence of highly elevated metallicities or abundances for any of our targets, suggesting that a super metal-rich environment is not a prerequisite for large, widely separated gas planet formation. The measurement of elemental abundances beyond carbon and oxygen also provides access to additional abundance ratios, such as Mg/Si, which could aid in further modeling of their giant companions.
Derivation and Application of a Scaling between Hinode/SP and SDO/HMI Vector Magnetic Fields to Improve Magnetic Field Extrapolations
Authors: Beck C. , Prasad A. , Hu Q. , Yalim M. S. , Gosain S. , Choudhary D. Prasad
Published: January 2025

Full-disk measurements of the solar magnetic field by the Helioseismic and Magnetic Imager (HMI) are often used for magnetic field extrapolations, but its limited spatial and spectral resolution can lead to significant errors. We compare HMI data with observations of NOAA 12104 by the Hinode Spectropolarimeter (SP) to derive a scaling curve for the magnetic field strength, B. The SP data in the Fe i lines at 630 nm were inverted with the SIR code. We find that the Milne–Eddington inversion of HMI underestimates B and the line-of-sight flux, Φ, in all granulation surroundings by an average factor of 4.5 in plage and 9.2 in the quiet Sun in comparison to the SP. The deviation is inversely proportional to the magnetic fill factor, f, in the SP results. We derived a correction curve to match the HMI B with the effective flux B
f in the SP data that scaled HMI B up by 1.3 on average. A comparison of non-force-free field extrapolations over a larger field of view without and with the correction revealed minor changes in connectivity and a proportional scaling of electric currents and Lorentz force (∝B ∼ 1.3) and free energy (∝B
2 ∼ 2). Magnetic field extrapolations of HMI vector data with large areas of plage and quiet Sun will underestimate the photospheric magnetic field strength by a factor of 5–10 and the coronal magnetic flux by at least a factor of 2. An HMI inversion including a fill factor would mitigate the problem.
Prospects for Observing High-redshift Radio-loud Quasars in the SKA Era: Paving the Way for 21 cm Forest Observations
Authors: Niu Qi , Li Yichao , Xu Yidong , Guo Hong , Zhang Xin
Published: January 2025

The 21 cm forest is a sensitive probe for the early heating process and small-scale structures during the epoch of reionization (EOR), to be realized with the upcoming Square Kilometre Array (SKA). Its detection relies on the availability of radio-bright background sources, among which the radio-loud quasars are very promising, but their abundance during the EOR is still poorly constrained due to limited observations. In this work, we use a physics-driven model to forecast future radio-loud quasar observations. We fit the parameters of the model using observational data of high-redshift quasars. Assuming Eddington accretion, the model yields an average lifetime of t
q ~ 105.5 yr for quasars at z ~ 6, consistent with recent results obtained from quasar proximity zone observation. We show that if the radio-loud fraction of quasars evolves with redshift, it will significantly reduce the abundance of observable radio-loud quasars in the SKA era, making 21 cm forest studies challenging. With a constant radio-loud fraction, our model suggests that a 1 yr sky survey conducted with SKA-LOW has the capability to detect approximately 20 radio-loud quasars at z ~ 9, with sufficient sensitivity to resolve individual 21 cm forest lines.

Authors: Tian Da-Chuan , Yang Yang , Wen Zhong-Lue , Xia Jun-Qing
Published: January 2025

Building a comprehensive catalog of galaxy clusters is a fundamental task for studies on structure formation and galaxy evolution. In this paper, we present Cluster Optical Search using Machine Intelligence in Catalogs (COSMIC), an algorithm utilizing machine learning techniques to efficiently detect galaxy clusters. COSMIC involves two steps, the identification of the brightest cluster galaxies and the estimation of cluster richness. We train our models on galaxy data from the Sloan Digital Sky Survey and the WHL galaxy cluster catalog. Validated against test data in the region of the northern Galactic cap, the COSMIC algorithm demonstrates high completeness when crossmatching with previous cluster catalogs. Richness comparison with previous optical and X-ray measurements also demonstrates a tight correlation. Our methodology showcases robust performance in galaxy cluster detection and holds promising prospects for applications in upcoming large-scale surveys.

We report the detection of repeated transits in the TESS light curves of TYC 8996-1013-1 (TIC 414929408) with a period of 2.77542 ± 0.00001 days and a width of 4.32 hr. We did not find significant variability in the transit time through the observations taken during TESS Sectors 37, 38, 64 and 65. The color B − V and the GAIA DR3 spectrum of TYC 8996-1013-1 point to a stellar temperature of ≈5000 K and radius of ≈1 R
⊙, and thus the transit model suggests a Neptune size for the candidate transiting planet (radius ≈ 25,000 km).

Authors: Proença Neto Marco , De Sousa Marcos
Published: January 2025

The standardisation and correction of taxonomic names in large biodiversity databases remain persistent challenges for researchers, as errors in species names can compromise ecological analyses, land-use planning and conservation efforts, particularly when inaccurate data are shared on global biodiversity portals.

We present pytaxon, a Python software designed to resolve and correct taxonomic names in biodiversity data by leveraging the Global Names Verifier (GNV) API and employing fuzzy matching techniques to suggest corrections for discrepancies and nomenclatural inconsistencies. The pytaxon offers both a Command Line Interface (CLI) and a Graphical User Interface (GUI), ensuring accessibility to users with different levels of computing expertise. Tests on spreadsheets derived from datasets published in the Global Biodiversity Information Facility (GBIF) demonstrated its effectiveness in identifying and resolving taxonomic errors. By mitigating the propagation of inaccuracies from researchers' datasets to global biodiversity databases, pytaxon supports more reliable conservation decisions and robust scientific investigations. Its contributions enhance data integrity and promote informed biodiversity management in a rapidly evolving global environment.

Authors: Wang Yanhong , Zhang Ke , Ruan Haihui , Niu Xiaodan , Zhang Jing , Chen Yaxin , Tao Hongxia
Published: January 2025

Purpose

To report the prevalence and risk factors of elder self-neglect (ESN) among community-dwelling older adults (
N
= 604).

Method

The current cross-sectional study was conducted from July 2019 to October 2020 in Lanzhou City, China. ESN was determined by the Scale of Elderly Self-Neglect, which evaluates five dimensions: (a) medical health and care, (b) environmental sanitation and personal hygiene, (c) mental health, (d) safety, and (e) social engagement. Frailty was assessed using the Physical Frailty Phenotype scale. Participants were asked whether they had bothersome and activity-limiting pain over the past 1 month. Characteristics associated with ESN were identified through multiple linear regression analyses.

Results

Mean age of participants was 71.34 years (
SD
= 7.15 years), and 255 (57.8%) were female. The prevalence of ESN among participants was 16.2%. Among the five dimensions of ESN, medical health and care accounted for the largest proportion (44%). Approximately 58% of participants were pre-frail and 11.4% were frail, and 45% reported experiencing bothersome pain. Older adults with a household monthly income per capita <2,000 RMB (β = −0.112,
p
< 0.05), larger waist circumference (β = 0.185,
p
< 0.001), pre-frailty (β = 0.176,
p
< 0.001), frailty (β = 0.420,
p
< 0.001), and pain (β = 0.102,
p
< 0.05) were more prone to ESN.

Conclusion

ESN is a prevalent issue among community-dwelling older adults. Frailty, pain, low economic status, and larger waist circumference are identified as independent risk factors for ESN. There is a need to improve the understanding of ESN among health care providers and policymakers. Personalized interventions aimed at preventing or addressing these risk factors may lead to improvements in ESN outcomes. [

Caregiver Tasks and Life Changes Among Family Caregivers of Stroke Survivors
Authors: Bakas Tamilyn , Cawthon Gabrielle , Israel Jahmeel , Miller Elaine L.
Published: January 2025

Purpose

Stroke family caregivers often struggle to provide care. The purpose of the current study was to determine: (a) ease or difficulty with caregiving tasks; (b) life changes because of providing care; and (c) relationship between caregiving tasks and life changes.

Method

A descriptive correlational design was used. Telephone interviews were conducted with 74 stroke caregivers. Tasks were measured using the Oberst Caregiving Burden Scale; life changes with the Bakas Caregiving Outcomes Scale.

Results

The most difficult tasks were managing survivor behaviors and the most negative life changes were lack of time for social activities. The easiest tasks were medical or nursing treatments, whereas the most positive life change was an improved relationship with the survivor. Tasks and life changes were different for each caregiver. Caregiver tasks and life changes were moderately correlated (
r
= 0.33,
p
< 0.01).

Conclusion

Caregiver tasks and life changes are important for designing strategies to support stroke caregivers. [

On multi-valued generalized $ \alpha $-nonexpansive mappings and an application to two-point BVPs
Authors: Ahmad Junaid , Kallel Imen Ali , Aloqaily Ahmad , Mlaiki Nabil
Published: January 2025

In recent years, many researchers have studied the fixed points of generalized $ \alpha $-nonexpansive (GAN) mappings, yet there has been limited research on multi-valued GAN mappings. In this paper, we focused on the class of multi-valued GAN mappings in the context of Banach spaces. We introduced a novel iterative process to find fixed points of these mappings and established weak and strong convergence theorems under mild conditions. To demonstrate the numerical efficiency of our new approach, we presented a supportive example and compare the accuracy of our method with existing iteration processes. To show practical usability of the research, we considered a larger class of boundary value problems (BVPs) and proved a convergence result with a supportive example. Our results are new and unify several results of the current literature.
« Aujourd’hui ma mère m’a dit que j’étais habillée comme un garçon »
Authors: Fabre Rachel
Published: January 2025

Cet article naît de la controverse autour du mouvement du #14Septembre, lancée par des collégiennes et lycéennes sur les réseaux socio-numériques, par lequel elles dénonçaient les restrictions vestimentaires sexistes de leurs établissements. L’analyse proposée est celle des stratégies de résistances à ces restrictions vestimentaires, les normes que ces résistances engagent, ainsi que leurs conditions de possibilité. L’enquête ethnographique a été réalisée dans un ensemble scolaire privé parisien, mais mon enquête s’est concentrée sur les collégien·nes. Au travers de cette ethnographie, on entrevoit l’émergence d’un ordre de genre concurrent à l’ordre de genre hégémonique, par des pratiques du genre différentes s’incarnant dans la parure (les vêtements, la coiffure, le maquillage) des adolescentes, prenant appui sur leurs ressources en termes de classe (la bourgeoisie) et de race (la blanchité). Il s’agira alors de conduire une analyse intersectionnelle de leurs pratiques vestimentaires, à l’aune du contexte scolaire, de leur position de fille et de leurs revendications féministes.
Una innovación estadística: las encuestas 1-2-3
Authors: Razafindrakoto Mireille
Published: January 2025

En el centro de las cuestiones de desarrollo, la economía informal ha sido durante mucho tiempo una terra incognita. Sin embargo, desempeña un papel decisivo en los países del Sur, ya que es la principal fuente de ingresos de la inmensa mayoría de los hogares, sobre todo de los más pobres. En estos países, la inmensa mayoría de los empleos se encuentran en la economía informal. Habida cuenta de lo que está en juego, el método de encuesta 1-2-3 ha permitido responder a un doble desafío, estadístico y económico: medir aquello que se escapa de la medición - la economía informal - y comprender su funcionamiento y su dinámica. Esta metodología fue desarrollada y consolidada por el IRD a través de diversos proyectos nacionales y regionales lanzados a principios de los años 90 y realizados en estrecha colaboración  con los institutos nacionales de estadística, en asociación con centros de investigación y universidades, organismos regionales, agencias y donantes. Este estudio repasa los trabajos realizados en tres países: Perú, Madagascar y Vietnam. Describe cómo los resultados de la investigación han generado impactos en los ámbitos social, económico, institucional, político, académico y de capacitación.

Published: January 2025

Green human resource management (GHRM) has been receiving more attention recently, although the discipline is still very new, and conceptual clarity has not yet been established. The VOSviewer software application was used to analyse a bibliometric evaluation of GHRM from 1913 to 2022 on Scopus and 574 papers on GHRM were examined. The goal of this study was to evaluate the GHRM field's volume, expanding tendency, global distribution, important journals, trailblazing authors, dominant nations, and dominant industries. In this work, word combinations were combined using logical operators, TITLE-ABS-KEY (“Green human resource management” OR “GHRM” OR “green HRM” OR “green HR” OR “Environmental Human Resource” OR “eco-friendly Practices” OR “Environmental Training” OR “Green Training”) AND (EXCLUDE (OA, “all”)) AND (EXCLUDE (PUBYEAR, 2023)) AND (LIMIT-TO (LANGUAGE, “English”)), thus expanding the gap. The review revealed that the GHRM is still a developing idea which aims to assist modern scholars.
