Expanding the International Role of China’s Educational Soft Power
Authors: Nukitrangsan Kulnaree
Published: February 2024

The objectives of this research are as follows: (1) to study China’s concept of using soft power to expand its role in international education; (2) to study the mechanisms and operational models used to expand China’s role in international education; and (3) to study the successful outcomes and negative impact of China’s expansion in this field. This is a qualitative research study that utilizes Joseph S. Nye’s concept of soft power in conjunction with document analysis. The research findings indicate that China’s expansion in international education is a tool for using China’s soft power. The mechanisms include establishing branches of the Confucius Institute, recruiting volunteer teachers, setting standards for Chinese language proficiency tests, promoting academic personnel exchange, and providing scholarships for international students. Additionally, China has raised the quality of its domestic educational institutions to meet international standards. China has also established an agency tasked with promoting Chinese language and culture at the international level, namely the Center for Language Education and Cooperation (CLEC), previously known as Hanban. The success of these efforts is evidenced by the number of Confucius Institute branches and classrooms, volunteer teachers, and international students receiving scholarships to study in China. These efforts have resulted in an improved image of China and a reduction in negative perceptions towards China from abroad.
The Visibility of Disabled Cross-Border Migrant Workers in Thailand in Migration Research
Authors: Khamkhom Nara
Published: February 2024

Migrant workers contribute significantly to Thai economic growth. Their importance attracts the attention of scholars around the world. Many researchers have investigated their lives before and while living in Thailand and when they return home. However, it is still questionable to what extent disabled migrants are included in these studies. This paper intends to answer this question by reviewing works conducted in Thailand related to migration and disabilities that appear in Thai and international journal citation databases. The results show that disabled migrant workers in Thailand are not yet clearly visible in migration research or migration data collection. This investigation suggests that the government, scholars, migration research institutes, and non-profit organizations should put disabled migrant workers on their research agendas. This can make them visible and raise society’s awareness of them, as with other groups of disabled people. The information can be used to support disabled migrants throughout the migration process to give them a better quality of life and prevent them from suffering human rights violations.

Published: February 2024

The incremental increase in the operation of technology has led to an increase in the quantum of data that's being reused over the Internet significantly over the time period. With the huge quantum of data that's being flown over the Internet, comes the script of furnishing security to the data, and this is where an Intrusion Detection System (IDS) comes into the picture and helps in detecting any virtual security pitfalls. Intrusion Detection System (IDS) is a system that monitors and analyzes data to descry any intrusion in the system or network. Interferers that find different ways to access into a network. The IDS which are being proposed is being enforced using technologies such as Machine Learning Algorithms to classify the attacks and detecting them whenever an attack happens and also to find which machine learning algorithm is suitable for detecting the attack. The Intrusion Detection System (IDS) plays an important part in deterring attacks. Still, arising technologies, like cloud computing, Internet of Things etc., induce a large volume of traffics, which may carry the inapplicable attributes that don't have any impact on discovery of assaults. To overcome these issues, features selection approaches (FSA) have been used to remove non- relevant features and find the important ones

Published: February 2024

Una de las tecnologías mas atractivas y actualmente en auge que se esta desarrollando rápidamente es el Gemelo Digital (Digital Twin en inglés, DT). Es bien conocido como un habilitador para la Industria 4.0. Tanto en la comunidad científica como industrial, el concepto, la tecnología y las aplicaciones asociadas al mismo, van generando controversia. Sigue habiendo una gran variedad de definiciones del mismo concepto. Aparentemente no parece haber una comprensión común de este término en la literatura. Se utiliza de forma diferente en diferentes disciplinas. La simulación basada en modelos ha sido, desde hace mucho tiempo, una herramienta común para el diseño en una fase inicial de planificación, pero no durante el tiempo de trabajo del sistema ya diseñado. En este trabajo se pretende abarcar una revisión histórica de este concepto. Mientras que muchas revisiones bibliográficas existentes se centran principalmente en la industria de manufactura, este artículo hará un enfoque en aplicaciones de los gemelos digitales en el campo de la Automática.

Spiritual Leadership and Intrinsic Motivation: The Roles of Supervisors' Developmental Feedback and Supportive Organizational Culture
Authors: Udahemuka Fidelis F. , Walumbwa Fred O. , Ngoye Ben
Published: February 2024

Organizational survival in today's dynamic and competitive business environment requires a holistic leadership approach that can intrinsically motivate employees to experience deeper meaning in their work beyond exchanging their labor for payment and fringe benefits. Anchored on self-determination
theory, this study examines how spiritual leadership relates to employees' intrinsic motivation. Specifically, the study proposes a theoretical model in which supervisors' developmental feedback mediates this relationship, whereas supportive organizational culture moderates it. Using a sample
of 448 employees from the financial sector in Kenya, results indicated that spiritual leadership, directly and indirectly, influenced intrinsic motivation, partially through supervisors' developmental feedback. Further, the results indicate that supportive organizational culture moderates
the relationship between spiritual leadership and intrinsic motivation, such that the relationship is stronger when supportive organizational culture is high rather than low. Implications of these findings and recommendations for future research are offered.

Published: February 2024

Introducción: Los musgos son organismos pioneros caracterizados por su alta capacidad de almacenamiento de agua y biomasa, por lo que desempeñan un papel estructural y funcional importante en los ecosistemas terrestres.Objetivo: Analizar si existe variación en la biomasa y capacidad de almacenamiento de agua en las especies de musgos como efecto del uso y manejo de sitios en un bosque de oyamel del Parque Nacional El Chico, Hidalgo, MéxicoMateriales y métodos: Se seleccionaron 10 sitios distribuidos en un intervalo altitudinal de 2781 a 2981 m: tres en la zona núcleo del parque, tres en la zona de amortiguamiento (turismo sin extracción de musgo) y cuatro en la zona con extracción de musgo. En cada sitio se establecieron parcelas y subparcelas para estimar la biomasa y capacidad de almacenamiento de agua (CAA) de las especies de musgos. Asimismo, se determinó la cobertura del estrato herbáceo y arbustivo de los sitios.Resultados y discusión: En todos los sitios predominó por biomasa Thuidium delicatulum (Hedw.) Schimp. var. delicatulum. La biomasa más alta de musgos (0.140 g∙cm-2) se encontró en un sitio de extracción (Esquillero), mientras que la mayor CAA (0.254 g∙cm-2) se estimó en sitios destinados al ecoturismo (La Orozca). En los sitios con extracción de musgos, la cobertura de los estratos herbáceo y arbustivo fue escasa y la biomasa muscinal incrementó.Conclusiones: El uso (conservación, ecoturismo) y manejo (extracción) del bosque afecta los valores de biomasa y CAA de los musgos y el porcentaje de cobertura del sotobosque (herbáceas y arbustos).

Published: February 2024

Tuberkulosis merupakan penyakit infeksi menular yang disebabkan oleh Mycobacterium tuberculosis yang menyerang paru – paru dan hampir seluruh organ tubuh lainnya. Penularannya dapat melalui terhirupnya droplet yang keluar dari penderita tuberkulosis. Inflamasi akut serta peningkatan kadar fibrinogen dan globulin plasma pada penderita tuberculosis paru terjadi, hal ini menyebabkan peningkatan nilai laju endap darah. Menurut World Health Organization (WHO) pada tahun 2013 Indonesia adalah negeri dengan prevalensi TB ke-5 tertinggi di dunia sebesar 410.000-520.000 kasus. Jenis penelitian ini bersifat deskriptif dengan menggunakan metode pemeriksaan Westergreen yang bertujuan untuk mengetahui nilai laju endap darah pada penderita Tuberkulosis. Penelitian ini dilaksanakan pada bulan Oktober-Desember 2023 di Rumah Sakit Islam Malahayati dengan sampel sebanyak 15 orang. Berdasarkan hasil penelitian diperoleh nilai laju endap darah yang normal sebanyak 3 orang (20%) dan yang meningkat sebanyak 12 orang (80%). Penyebab meningkatnya laju endap darah karena adanya infeksi akut, kronis maupun peradangan akut dalam tubuh serta meningkatnya globulin dan fibrinogen. Hal ini dapat juga disertai dengan pengaruh obat, nekrosis, adanya penyakit diabetes dan kolesterol, demam, rematik, dan kondisi stress fisiologis. Sedangkan laju endap darah yang normal ini disebabkan oleh karena penderita sudah melakukan penerapan pola makan teratur dan hidup yang sehat salah satu nya dengan cara membatasi konsumsi minuman beralkohol dan berhenti merokok. Saran bagi pasien penderita TBC sebaiknya mengkonsumsi obat dan pola makan teratur serta selalu melakukan pemeriksaan berkala agar penyakit ini dapat terkontrol.

Bacteria obtained from cow-dungs from selected slaughtering points in Awka central abattoir were assessed for cellulose degradation. The qualitative screening of the isolates was determined by culturing the isolates on a cellulose selective medium. The isolates were obtained and identified as Serratia marcescens, Streptococcus mutans, Pseudomonas aeruginosa, Escherichia coli, Salmonella typhi, Bacillus subtilis and Lactobacillus spp. Three of the isolates with the highest cellulolytic activity are Pseudomonas aeruginosa, Bacillus subtilis and Streptococcus mutans. Pseudomonas aeruginosa gave the highest diameter clear zone value of 12mm+0.25mm Streptococcus spp. follows with clear zone of 11mm+1.02mm and Bacillus subtilis had the least diameter clear zone of 10mm+1.04mm. The three isolates were selected for optimization because they had a clear zone up to 10mm and above. These isolates were subjected to qualitative screening by culturing the isolates in a liquid medium with different incubation periods (12, 24, 48, 60, 72, 84 and 96hrs) at shack and static conditions. Potential activities of Fpase and CMC-ase were found in Pseudomonas aeruginosa (0.94u/m), Bacillus subtilis (0.88u/m) and Streptococcus mutans (0.6u/m) all at 48hrs incubation respectively. Microbes in cow dung have a potential to be Cellulolytic as the degradation of cellulose is an environmental friendly approach that can reduce the accumulation of agricultural wastes.

Published: February 2024

Considering the ongoing era of globalization, the importance of teaching Indonesian to foreign residents is increasing. Indonesian, as the official language of Indonesia, has important meaning as the main language in Southeast Asia. In addition, this language is recognized as one of the official languages of ASEAN and has an important function in encouraging international cooperation. As a result, more and more people from various countries are choosing to master Indonesian for academic, commercial or personal purposes. However, empirical evidence shows that several challenges hinder cultural exchange in BIPA education. These include the lack of Indonesian language skills among international students at the elementary level, the rise of bilingualism in Indonesian society, cross-cultural differences, the speed of communication in Indonesian society, and even low motivation among international students. This report explores the challenges and strategies involved in teaching at Bandung State University. This research aims to increase the effectiveness of teaching Indonesian to non-native students by overcoming various challenges faced in the teaching and learning process. This research uses a qualitative approach and uses in-depth interviews as the main method of data collection. The research involved 8 Indonesian language lecturers from various countries who taught non-native speakers. Research findings show that the main problem is the complicated Indonesian grammar, which is an obstacle for non-native speakers to understand. In addition, it is very important to modify the teaching methodology to meet the preferences and learning needs of international students. One approach to overcome this problem is to simplify grammar teaching by using practical illustrations. In addition, this research reveals the importance for BIPA teachers to consider the balance between language skills and non-skills material, cross-cultural factors for both students and teachers, student characteristics, students' goals in learning BIPA and selecting learning methods that suit their needs. Target. These features can be enhanced by incorporating active learning methodologies, such as role-playing, into a student-centered teaching style tailored to the specific needs and preferences of international students.

The results showed that the factors that influence the decline in farmers' interest in cultivating soybeans are sources of plant pest and disease risks, sources of input risk and soybean production techniques and sources of risk in the business environment. Some pests and diseases that often arise and attack soybean commodities are leaf spot, whitefly, caterpillar/pod caterpillar, leafhopper, stink bug, bacterial wilt and javelin/ladybug. The Risks from nature is that high rainfall and changing climatic conditions also make it difficult for farmers to grow soybeans. The risk from the production input sector is the unstable quality, quantity, and price of seeds, pesticides and fertilizers. Moreover, other influencing factors exist, such as the entry of imported soybeans, price games at middlemen, the absence of a lower price limit for local soybeans, and post-harvest limitations.

Abstract. Water-insoluble carbon (WIOC) constitutes a substantial portion of organic carbon (OC) and contributes significantly to light absorption by brown carbon (BrC), playing pivotal roles in climate forcing and human health. China as hotspots regions with high level of OC and BrC, information regarding the sources and light-absorbing properties of WIOC on national scale remains scarce. Here, we investigated the light-absorbing properties and sources of WIOC in ten representative urban cities across China. On average, WIOC accounted for 33.4 ± 7.66 % and 40.5 ± 9.73 % of the concentrations and light-absorbing efficiency at 365 nm (Abs365) of extractable OC (EX-OC, comprising relatively hydrophobic OC [WIOC and humic-like substances: HULIS-C], and hydrophilic OC [non-humic-like substances: non-HULIS-C]). The mass absorption efficiency of WIOC at 365 nm (MAE365) was (1.59 ± 0.55 m2/gC) comparable to that of HULIS (1.54 ± 0.57 m2/gC) but significantly higher than non-HULIS (0.71 ± 0.28 m2/gC), indicating that hydrophobic OC possesses a stronger light-absorbing capacity than hydrophilic OC. Biomass burning (31.0 %) and coal combustion (31.1 %) were the dominant sources of WIOC, with coal combustion sources exhibited the strongest light-absorbing capacity. Moreover, employing the simple forcing efficiency (SFE300–700nm) method, we observed that WIOC exhibited the highest SFE300–700nm (6.57 ± 5.37 W/g) among the EX-OC fractions. The radiative forcing of EX-OC was predominantly contributed by hydrophobic OC (WIOC: 39.4 ± 15.5 % and HULIS: 39.5 ± 12.1 %). Considering the aromaticity, sources, and atmospheric processes of different carbonaceous components, we propose a light-absorbing carbonaceous continuum, revealing that components enriched with fossil sources tend to possess stronger light-absorbing capacity, higher aromatic levels, increased molecular weights, and greater recalcitrance in the atmosphere. Reducing fossil fuel emissions emerges as an effective means of mitigating both gaseous (CO2) and particulate light-absorbing carbonaceous warming components.

Abstract. Peatlands pools are unvegetated, inundated depressions that cover up to 30 % of the surface of many temperate and boreal peatlands and that are net carbon (C) sources within C-accumulating ecosystems. The emission of carbon dioxide (CO2) and methane (CH4) from peatland pools comes from the degradation of organic matter (OM) that comprise the surrounding matrix. It is, however, not clear how decomposition rates in pools, which define their function and distinguish them from other aquatic ecosystems, vary spatially and what mechanisms drive these variations. We quantified rates of OM decomposition from fresh litter at different depths in six pools of distinct morphological characteristics in a temperate ombrotrophic peatland using litterbags of Sphagnum capillifolium and Typha latifolia over a 27-month period and measured potential CO2 and CH4 production of pool sediments in laboratory incubations. Rates of decomposition were faster for T. latifolia than S. capillifolium and, overall, faster at the pool surface and decreased with increasing depth. Pool sediment chemistry was variable among pools and drove the production of CH4 and CO2 from sediments, with decreasing CO2 production with increasing OM humification and decreasing CH4 production with increasing nitrogen-to-phosphorus ratio. Both CH4 and CO2 production from pool sediments were higher in the 1 m deep pools, but similar in the shallow < 1 m and the > 1.5 m deep pools. Our results show that OM decomposition in peatland pools is highly variable and related to OM chemistry, but decomposition depends primarily on the environmental conditions in which it occurs, with differences in both fresh litter and pool sediment decomposability as a function of decreasing O2 concentrations, light, and temperature with increasing depth in the pools.

Abstract. The capacity of particulate matter (PM) to generate reactive oxygen species (ROS) in vivo leading to oxidative stress, is thought to be a main pathway for the health effect of PM inhalation. Exogenous ROS from PM can be assessed by acellular oxidative potential (OP) measurements as a proxy of the induction of oxidative stress in the lungs. Here, we investigate the importance of OP apportionment methods on OP repartition by PM sources in different types of environments. PM sources derived from receptor models (e.g. EPA PMF) are coupled with regression models expressing the associations between PM sources and OP measured by ascorbic acid (OPAA) and dithiothreitol assay (OPDTT). These relationships are compared for eight regression techniques: Ordinary Least Squares, Weighted Least Squares, Positive Least Squares, Ridge, Lasso, Generalized Linear Model, Random Forest, and Multilayer Perceptron. The models are evaluated on one year of PM10 samples and chemical analyses at each of six sites of different typologies in France to assess the possible impact of PM source variability on OP apportionment. Source-specific OPDTT and OPAA and out-of-sample apportionment accuracy vary substantially by model, highlighting the importance of model selection depending on the datasets. Recommendations for the selection of the most accurate model are provided, encompassing considerations such as multicollinearity and homoscedasticity.

Abstract. A tipping point is defined by the IPCC as a critical threshold beyond which a system reorganizes, often abruptly and/or irreversibly. Tipping points can be crossed solely by internal variation in the system or by approaching a bifurcation point where the current state loses stability and forces the system to move to another stable state. It is currently debated whether or not Dansgaard-Oeschger (DO) events, abrupt warmings occurring during the last glacial period, are noise-induced or caused by the system reaching a bifurcation point. It can be shown that before a bifurcation point is reached there are observable changes in the statistical properties of the state variable. These are known as early warning signals and include increased fluctuation and correlation time. To express this behaviour we propose a new model based on the well-known first order autoregressive process (AR), with modifications to the correlation parameter such that it depends linearly on time. In order to estimate the time evolution of the correlation parameter we adopt a hierarchical Bayesian modeling framework, from which Bayesian analysis can be performed using the methodology of integrated nested Laplace approximations. We then apply the model to segments of the oxygen isotope ratios from the Northern Greenland Ice Core Project record corresponding to 17 DO events. Early warning signals were detected and found statistically significant for a number of DO events, suggesting that such events could indeed be caused by approaching a bifurcation point. The methodology developed to perform the given early warning analyses can be applied more generally, and is publicly available as the R-package INLA.ews.

Abstract. Early-life stages play a key role in the dynamics of bipartite life cycle marine fish populations. Difficult to monitor, observations of these stages are often scattered in space and time. While Mediterranean coastlines have been highly surveyed, no effort was made to assemble historical observations. Here we build an exhaustive compilation of dispersal traits for coastal fish species, considering in-situ observations and growth models. Our database contains over 110 000 entries collected from 1993 to 2021 in various subregions. All observations are harmonized to inform on dates and geolocations of both spawning and settlement, along with pelagic larval durations. When applicable, missing dates and associated confidence intervals are reconstructed from Dynamic Energy Budget theory. Statistical analyses allow revisiting traits’ variability and revealing sampling biases across taxa, space and time, hence providing recommendations for future studies and sampling. Comparison of observed and modelled entries gives hints to improve the feed of observations into models. Overall, this long-term database is a crucial step to investigate how marine fish populations respond to global changes across environmental gradients.
