Plastic wastes are a major hazard for the environment and their use in the construction industry is increasing day by day. The major drawback of the use of plastic in concrete is an exceptional reduction in strength and workability. This research work explores the effect of sand coating on two types of recycled plastic aggregates, high-density polyethylene (HDPE) and electronic-wastes (E-wastes), as partial replacement of natural aggregates. The replacement ranged from 0% to 30% along with the use of super plasticizer SP-675 and wet lock sealant. Both recycled plastic aggregates are crushed, melted, and ground to convert them into aggregates of 20 mm size. The workability of concrete containing uncoated recycled plastic aggregates (HDPE and electronic wastes), SP-675, and wet lock sealant has been found to be higher than controlled concrete samples with 0% recycled aggregates. Compressive strength, split tensile strength, and flexural strength of such type of concrete is lower than the controlled concrete samples due to the weak bond between the plastic aggregates and Ordinary Portland Cement. After applying the sand coating to improve bonding, the workability is reduced compared to uncoated samples whereas the compressive strength, split tensile strength and flexural strength of the sand coated plastic aggregate concrete is higher than uncoated plastic aggregate concrete. There is a significant increase in workability of concrete after the addition of SP-675 when added as 2% by weight of cement. The wet lock sealant positively affects the strength properties of concrete. It is recommended that the durability of concrete containing uncoated and sand coated recycled plastic aggregates be further explored in future studies.

Published: March 2022

Foamed ceramic foam concrete composite wall was prepared by a direct casting method. Compressive and tensile tests were carried out on different densities of foamed ceramic boards. Changing rules of interface bonding properties of the composite wall under the influence of foamed concrete age, the surface treatment of foamed ceramic boards, and exposure to freeze–thaw cycles were studied; and the failure mechanism was analyzed and discussed. The results show that a foamed ceramic board with a density of 410 kg/m3 is suitable for a panel of composite wallboard; when the age of the foam concrete increases from 3 to 7 days, and the interface bond strength of the composite wallboard increases, then the bonding strength of the composite wallboard gradually decreases with the increase in age; with the increase in freeze–thaw cycles, the interface bond strength of the composite wallboard decreases gradually. The interface agent was pre-painted on the foamed ceramic board, which can improve the interface bonding strength of the composite wallboard. The drying, shrinkage, and freezing and thawing cycles of the foam concrete have a great influence on the interface bond strength of the composite wallboard. The perforated long hole and rubber sleeve can be used to improve the safety of the composite wallboard.
Environmental Sustainability and Supply Resilience of Cobalt

Published: March 2022

Cobalt (Co) is an essential metal for the development of energy-transition technologies, decarbonising transportation, achieving several sustainable development goals, and facilitating a future net zero transition. However, the supply of Co is prone to severe fluctuation, disruption, and price instabilities. This review aims to identify the future evolution of Co supply through technologically resilient and environmentally sustainable pathways. The work shows that advances in both primary and secondary sources, Co mining methods and recycling systems are yet to be fully optimised. Moreover, responsible sourcing from both large mines and small artisanal mines will be necessary for a resilient Co supply. Regulatory approaches may increase transparency, support local mining communities, and improve secondary Co recovery. Novel Co supply options, such as deep-sea mining and bio-mining of tailings, are associated with major techno-economic and environmental issues. However, a circular economy, keeping Co in the economic loop for as long as possible, is yet to be optimised at both regional and global scales. To achieve environmental sustainability of Co, economic incentives, regulatory push, and improved public perception are required to drive product innovation and design for circularity. Although the complexity of Co recycling, due to lack of standardisation of design and chemistry in batteries, is an impediment, a sustainable net zero transition using Co will only be possible if a reliable primary supply and a circular secondary supply are established.
Green Fences for Buenos Aires: Implementing Green Infrastructure for (More than) Air Quality

Published: March 2022

Schoolyards in North America and Europe are increasingly using green fences as one measure to protect vulnerable populations from localised air pollution. This paper assesses the possibilities and limits for mobilising this format of site-specific green infrastructure in cities in low- and middle-income countries beset by air pollution and multiple other socio-environmental challenges, and particularly questions the definition of green fences as a green infrastructure for air quality (GI4AQ). We applied several qualitative and action research methods to the question of green fence implementation in Buenos Aires, Argentina—a Latin American city with weak air-quality policies, limited green infrastructure, and little experience with nature-based solutions. Firstly, we conducted a literature review of the role that urban vegetation and ecosystem services may play in AQ policy and the implementation barriers to such approaches globally and in the city. Secondly, we planned, designed, constructed, maintained, and evaluated a pilot green fence in a school playground. Thirdly, we carried out supplementary interviews with stakeholders and expert informants and compiled project members’ narratives to respectively characterise the barriers that the project encountered and delineate its attributes based on the associated actions that we took to overcome such barriers to implementation and complete the pilot. Our findings identify multiple barriers across seven known categories (institutional, engagement, political, socio-cultural, built environment and natural landscape, knowledge base and financial) and highlight examples not previously considered in the extant international literature. Furthermore, learning from this experience, the paper proposes an expanded model of green infrastructure for air quality plus multi-dimensional co-benefits (GI4AQ+) to increase implementation chances by attending to local needs and priorities.
Credit Card Use, Hedonic Motivations, and Impulse Buying Behavior in Fast Fashion Physical Stores during COVID-19: The Sustainability Paradox
Authors: Gawior Barbara , Polasik Michal , del Olmo Josep Lluís
Published: March 2022

The health crisis caused by COVID-19 has affected consumption and payment patterns worldwide. Consumers have had to change their habits and deal with new sanitation guidelines and have often struggled with lengthy infrastructure closures. These factors significantly influenced both the choice of payment methods and purchase decisions made by consumers. Still, consumption patterns during the pandemic as a new social situation have not yet been thoroughly investigated. As the unsustainable consumption of resources is an important issue, this paper aims to analyze the relationship between credit card use, hedonic motivations, and its impact on the impulsive buying behavior in physical fast fashion stores during the COVID-19 pandemic in Spain. For this purpose, an online survey was conducted on a sample of 300 regular fast fashion buyers in physical stores. Structural equation modelling was used for the data analysis. The results show that there is a significant relationship between credit card use and impulse buying behavior for fast fashion in physical stores, as well as between credit card use and social shopping. It is also observed that hedonic motivations such as gratification shopping, value shopping, novelty-seeking shopping, and adventure-seeking shopping are related to impulse buying behavior. Therefore, this evidences the unsustainable overconsumption, thereby having a higher negative environmental and social impact. With the increased popularity of cashless payment methods, including credit cards relaxing tighter budgets during the pandemic, fast fashion impulse buying should be considered an important issue in individual, social and environmental well-being. Consequently, the need for more responsible consumption and sustainability-focused value orientation arises so as to mitigate the environmental impact of the fast fashion industry.

Published: March 2022

The process of healthy aging might be reconsidered, based on the nonfatal outcomes of falls in older adults. Flywheel training is a relatively new training method used by different age groups, which enables the muscles to contract at maximum force in minimum time. The study aim was to summarize the relevant literature about the effects of flywheel training in older adults and to determine its efficiency and feasibility. PRISMA guidelines were followed for both the search and analysis. Electronic databases (Google Scholar, PubMed, Science Direct, Scopus, Web of Science and SPORTDiscuss) yielded 9915 studies, but we have included studies published in English between 2005 and 2021, cross-sectional and pre-post treatments, with older adults (≥60 years) as the sample, where flywheel training was conducted. A total of nine studies have met the pre-defined criteria and entered the systematic review, with a total of 216 participants, both male and female. After analyzing the obtained results, it can be concluded that flywheel training showed physical, neuromuscular, and functional improvements in older adults. However, the review did not reveal an optimal duration, frequency, intensity, or volume. Furthermore, it can be stated that this training method can be considered as an appropriate form of activity in older adults, as a tool for improving overall health.

Pulmonary microbial invasion frequently occurs during AIDS progression in HIV patients. Inflammatory cytokines and other immunoregulatory factors play important roles in this process. We previously established an AIDS model of SIVmac239 infection in northern pig-tailed macaques (NPMs), which were divided into rapid progressor (RP) and slow progressor (SP) groups according to their AIDS progression rates. In this study, we performed 16S rDNA and transcriptome sequencing of the lungs to reveal the molecular mechanism underlying the difference in progression rate between the RPs and SPs. We found that microbial invasion in the RP group was distinct from that in the SP group, showing marker flora of the Family XI, Enterococcus and Ezakiella, and more Lactobacilli. Through pulmonary transcriptome analysis, we found that the transcription factor ZNF683 had higher expression in the SP group than in the RP group. In subsequent functional experiments, we found that ZNF683 increased the proliferation and IFNγ secretion ability of CD8+ T cells, thus decreasing SIV or HIV replication, which may be related to AIDS progression in SIVmac239-infected NPMs. This study helps elucidate the various complexities of disease progression in HIV-1-infected individuals.

This study aimed to exercise the Sanger sequencing strategy for screening of variants among confirmed COVID-19 cases and validate our strategy against NGS strains in Hiroshima retrieved from GISAID. A total of 660 samples from confirmed COVID-19 cases underwent screening for variants by Sanger-based partial sequencing to the targeted spike gene (nt22,735~nt23,532) using an in-house-developed primer set. The identification of variants was done by unique checkpoints of base nucleotide changes in the targeted spike gene. Moreover, we amplified one full-length genome using Sanger method and an in-house-developed primer library. Using NGS strains of the same sampling period from GISAID, a phylogenetic tree was constructed to examine the distribution pattern of variants in Hiroshima and to validate our Sanger method. The modified primer set provided 100% validation and 99.2% amplification. PANGO Lineage R.1 was detected in late in the third wave, followed by Alpha (B.1.1.7) domination in the fourth wave, Delta (B.1.617.2) domination in the fifth wave, and Omicron (B.1.1.529) domination in the sixth wave, and there was no significant difference in viral copies between variants (p = 0.09). The variants showed different transmission patterns, but the distribution of variants is consistent to that shown by the phylogenetic tree. The Sanger method also provided successful amplification of the full-length genome of the SARS-CoV-2 virus. Our Sanger sequencing strategy was useful for the screening of SASR-CoV-2 variants without the need for full-genome amplification. The modified primer set was validated to use universally, which allows an understanding of the variants’ distribution in real time and provides the evidence for policy-making and the formulation or modification of preventive strategies.

Published: March 2022

Alzheimer’s disease (AD) has emerged as a growing threat to human health. It is a multifactorial disorder, in which abnormal amyloid beta metabolism and neuroinflammation have been demonstrated to play a key role. Intrathecal inflammation can be triggered by infections and precede brain damage for years. We analyzed the influence of infections of the central nervous system on biomarkers that are crucially involved in AD pathology. Analyses of the cerebrospinal fluid (CSF) levels of Aβ1–42, Aβ1–40, Tau, and pTau proteins were performed in 53 children with neuroinfections of viral (n = 26) and bacterial origin (n = 19), and in controls (n = 8). We found no changes in CSF amyloid Aβ1–42 concentrations, regardless of etiology. We showed an increase in tau and phosphorylated tau concentrations in purulent CNS infections of the brain, compared to other etiologies. Moreover, the total concentrations of tau in the CSF correlated with the CSF absolute number of neutrophils. These findings and the Aβ 42/40 concentration quotient discrepancies in CFS between meningitis and encephalitis suggest that infections may affect the metabolism of AD biomarkers.
Seasonal Enhancement of Nitrogen Removal on Domestic Wastewater Treatment Performance by Partially Saturated and Saturated Hybrid Constructed Wetland
Authors: Contreras José , López Daniela , Gómez Gloria , Vidal Gladys
Published: March 2022

The aim of this study is to evaluate seasonal enhancement of nitrogen removal on domestic wastewater treatment performance by partially saturated and saturated HBCWs. To achieve this, two HBCWs consisting of a vertical subsurface flow constructed wetland, followed by a horizontal subsurface flow constructed wetland (VSSF-HSSF) were evaluated. Two saturation levels were used: (a) partially saturated HB1:VSSF1 (0.6 m)-HSSF1 (0.15 m), (b) saturated HB2: VSSF2 (0.8 m)-HSSF2 (0.25 m). Each unit was planted with Schoenoplectus californicus and was operated for 297 days. The removal efficiencies in HB1 and HB2 were above 70%, 86%, 77% and 55% for chemical oxygen demand (COD), total suspended solids (TSS), nitrogen as ammonium (NH4+-N), and total nitrogen (TN), respectively. For VSSF, a higher level of saturation (from 0.6 to 0.8 m) meant a decrease of 17% in the TN removal efficiencies, and for HSSF, an increase from 0.15 to 0.25 m of saturation meant a decrease of 11 and 10% in the NH4+-N and TN removal efficiencies, respectively. Thus, the increase of saturation level in HBCWs reduces the transformation and/or removal of components of the wastewaters to be treated, particularly nitrogen. Through this research, the possibility of optimizing the transformation of nitrogen with partially saturated hybrids can be examined.

Published: March 2022

Cascade pump station irrigation districts (CPSIDs) consume vast amounts of irrigation water and energy. The aim of this study was to adjust the spatial patterns of crops and irrigation technologies in the CPSID to reduce the consumption of water and energy under the condition of conserving crop irrigation water. The irrigation district (ID) is divided into several sub-districts according to the topography elevation difference and the distribution of cascade pump stations (CPSs). The mathematical models of the irrigation water and energy consumption in each sub-district were established based on the relationship between the spatial patterns of crops and irrigation technologies in each sub-district. According to the present situation of the Jingdian Phase I Irrigation District in the arid region of northwest China, three modes of adjusting the crop planting structure and drip irrigation area were proposed. Based on the combination of these modes, three schemes of the spatial patterns of crops and irrigation technologies were generated. The annual energy consumption and irrigation water consumption of each sub-district in the ID of these three schemes were obtained through simulation. Compared with the present spatial patterns of crops and irrigation technologies in the Jingdian Phase I Irrigation District, Scheme 3 has the best water-saving and energy-saving effects, with an annual water saving and energy saving of 1753 × 104 m3 and 2898 × 104 kWh, and the water-saving rate and energy-saving rate were 12.34% and 15.74%, respectively. This paper also shows that the synchronous adjustment of crops and irrigation technologies among the sub-districts of ID can achieve significant water-saving and energy-saving effects.

High-mountain lakes are unique ecosystems with very few examples at tropical latitudes for experimentation. A two-year, high-frequency meteorological and water-column dataset from the crater of the Nevado de Toluca volcano, in Mexico, at an altitude of about 4200 m above sea level, allowed for the study of temporal changes in the thermal structure, water level, and water balance in the Lakes El Sol and La Luna, separated by about 500 m by a lava dome. Annual fluctuations in the water level of the lakes and calculations of the annual variability of the water balance showed that the lakes accumulated almost four times less water from rainfall than expected. Furthermore, the temperature measured at a depth of 15 cm in the bottom sediments of Lake El Sol revealed an unexpected warming during the cold season. Estimated heat fluxes through the lake bottom were less than 0.3 W m−2 during the winter and less than 0.1 W m−2 during the rest of the year. Although the variability of the hydrometeorological regime of high-mountain lakes remains relatively poorly understood, our results significantly improve the understanding of these complex processes of stratification and mixing in these unique lake ecosystems.
Optimizing Parameters for the Downscaling of Daily Precipitation in Normal and Drought Periods in South Korea

Published: March 2022

One important factor that affects the performance of statistical downscaling methods is the selection of appropriate parameters. However, no research on the optimization of downscaling parameters has been conducted in South Korea to date, and existing parameter selection methods are dependent on studies conducted in other regions. Moreover, several large-scale predictors have been used to predict abnormal phenomena such as droughts, but in the field of downscaling, parameter optimization methods that are suitable for drought conditions have not yet been developed. In this study, by using the K-nearest analog methodology, suitable daily precipitation downscaling parameters for normal and drought periods were derived. The predictor variables, predictor domain, analog date size, time dependence parameters, and parameter sensitivity values that are representative of South Korea were presented quantitatively. The predictor variables, predictor domain, and analog date size were sensitive to the downscaling performance in that order, but the time dependency did not affect the downscaling process. Regarding calibration, the downscaling results obtained based on the drought parameters returned smaller root mean square errors of 1.3–28.4% at approximately 70% of the stations compared to those of the results derived based on normal parameters, confirming that drought parameter-based downscaling methods are reasonable. However, as a result of the validation process, the drought parameter stability was lower than the normal parameter stability. In the future, further studies are needed to improve the stability of drought parameters.

En respuesta a cuán y cómo de bien se vive, la presente investigación tuvo como objetivo generar un índice de desarrollo considerando los fundamentos filosóficos, culturales, costumbristas y lingüísticos del paradigma prevalente del Vivir Bien. El andamiaje estadístico - matemático desarrollado se ajustó al modelo boliviano basado en los 25 principios propuestos por Choquehuanca. Partiendo de los fundamentos de la tetraléctica y la tetrasociología, se formaron pautas para desarrollar un propio modelo ontológico que ayude a definir las dimensiones y las variables que mejor describan este paradigma. Como resultado se propuso un índice conceptualmente robusto – Índice del Vivir Bien (IVB) – que supera los índices de pobreza, desarrollo humano y otras métricas, configurado en un sistema en el que la Bioeconomía juega un rol preponderante para llegar a la pentaléctica. Se resalta la importancia de habilitar una conexión con la economía, lo social y medioambiental, que permita consolidar una base ética, moral   e ideológica que promueva el Vivir Bien como fundamento transversal, tanto interna como internacionalmente.

Decision-making based on International Society of Urological Pathology Gleason-scores obtained from transrectal needle biopsy of the Prostate: How Accurate Could We Be ?
Authors: KAZAZ İlke Onur
Published: March 2022

Objective: The decision about the treatment of localized prostate cancer (PC) depends mainly on the histopathological results of transrectal needle biopsy. The agreement between the results of transrectal needle biopsies and radical prostatectomy specimens were reported to be varying. In this study, we aimed to investigate one institution’s homogenous repertory. A fair agreement could be revealed, and probable strategies to improve the rate of agreement are discussed.

Materials and Methods: 230 eligible patients who underwent radical prostatectomy (RP) and transrectal ultrasound guided prostate biopsy (TRUS-Bx) in our instutition were included in the study. Demographic characteristics, PSA levels (ng/ml) prior to TRUS-Bx, International Society of Urological Pathology (ISUP) Gleason group grades obtained from TRUS-Bx and RP were recorded and evaluated for concordance.

Results:137 of 250 patients RP pathology ISUP Gleason grades were compatible with TRUS-Bx pathology results (%59,6). 20 of 125 (%16) patients who reported to be ISUP Gleason grade 2 or 3 or 4 or 5 in initial biopsy found to be downgraded and 42 of 147 patients (29%), reported to have ISUP Gleason grade 1 upgraded in the final pathology.

Conclusion: In the diagnosis of PC, TRUS-Bx is an insufficient method to show the correct ISUP Gleason grade in radical prostatectomy specimen pathology.

Frequency analysis was conducted to determine preferences, whereas an independent sample t-test and one-way analysis of variance were administered to verify any differences in preferences according to gender and grade. The findings are as follows. First, out of the 12 principles that should be considered in the design of instructional videos, the students most preferred the review quiz principle. Moreover, this factor was found to exert the greatest influence on engagement. Second, incorporating real-life situation principles into instructional videos also had a significant impact on engagement. Third, female students expressed higher levels of preference than did male students in terms of the preview, course content on screen, and review quiz principles. Fourth, sophomores preferred the review quiz principle more than the freshmen did. The results of the present study are in line with those of previous research in that the effective instructional design of multimedia lessons requires reducing extraneous processing, managing essential processing, and fostering generative processing. Particularly, the study found that Korean students value video lectures with generative activities for meaningful learning. Based on the findings of the study, pedagogical considerations of the design of recorded lectures and its structure for active engagement, and suggestions for future studies are provided.

Konsep dasar dari simulasi sistem pembangkitan line code untuk transmisi Pulse Code Modulation (PCM) yaitu bagian transmisi dari encoding dan decoding pada PCM yang mana mempunyai tugas mengubah bentuk sinyal agar tidak berubah pada saat proses pengiriman. Salah satu pemahaman mengenai sistem komunikasi umumnya dengan instrument sentuhan langsung. Namun, kegiatan praktik menjadi kurang maksimal apalagi dikala pandemi seperti ini yang kegiatan praktik menjadi lebih efisien dan performa yang menurun dari instrument yang memadai juga salah satu penyebabnya. Pada penelitian ini disimulasikan sistem pembangkitan line code pada transmisi PCM yang dapat mengubah bentuk biner dari hasil pengkodean menjadi bentuk line code yang tertuang dalam pemograman bahasa C dengan aplikasi simulasi program. Pengujian dilakukan dengan memasukan 17 deretan data hasil kuantisasi Pulse Amplitudo Modulation (PAM) menjadi bentuk biner yang nantinya akan diubah menjadi bentuk line code. Deretan biner yang digunakan dengan panjang 7-bit yang mana 6-bit sebagai data 1-bit sebagai penanda most significant bit (MSB). Hasil pengujian menunjukan bentuk line code yang telah diimplementasikan sesuai dengan dasar teori.

La siguiente tesis tiene como objetivo el desarrollo y caracterización fotométrica de fuentes de iluminación basadas en LEDs con la posibilidad de aplicarlas en la Terapia Fotodinámica (TFD) del cáncer, así como también, a proponer introducir mejoras en protocolos de aplicación preestablecidos. Brevemente, en la TFD, se utiliza luz de longitud de onda y potencia apropiada a las características del espectro de absorción de la droga fotoactivable Fs que, en presencia de oxígeno, desencadena un proceso fotodinámico que induce a las células a morir. En el siguiente trabajo de tesis se realizaron experimentos aplicativos de la TFD en cultivos celulares bidimensionales, tridimensionales y en modelo animal, empleando la temoporfin (meta-tetra(hidroxifenil)clorina) como fotosensibilizador y un láser médico y lámparas construidas con LEDs. Se analizan experimentos realizados empleando distintas longitudes de onda, para mejorar la selectividad de la terapia y se sigue la terapia mediante las medidas de fluorescencia y termografía infrarroja. Esto permite proponer mejoras concretas en los protocolos de la TFD. Finalmente, se presentan casos en pacientes utilizando herramientas complementarias a la aplicación de la TFD.
Preparing Teachers to Facilitate Engagement in Reading Intervention Through Embedded Behavioral Supports
Authors: Lindström Esther R. , Roberts Garrett J.
Published: March 2022

Reading intervention sessions are most effective when students are engaged. Combined interventions that target both reading and engagement may produce stronger outcomes in both domains than separate interventions for each goal. They also have advantages of being efficient, thus requiring fewer resources. However, planning and executing combined interventions may be challenging to novice teachers. This article presents guidance for teacher educators to address combined reading and engagement support interventions in the context of a university reading methods course and applied fieldwork setting. The article outlines the importance of engagement to reading instruction and offers a framework for training teachers to implement reading interventions with embedded engagement supports, toward the overall goal of maximizing effectiveness of the reading instruction. Resources, tools, and sample activities are presented to further illustrate these concepts and facilitate their application in classrooms.
Efectos de ampliar la jornada escolar en América Latina: una revisión bibliográfica
Authors: Ceballos Fernando
Published: March 2022

A literature review is presented on the effects of school day extension programs implemented in various Latin American countries. According to their objects of interest, the studies are grouped into four types of impacts: a) school performance, b) academic and career paths, c) labor, and d) school organization and culture. A predominance of quantitative evaluations that analyzed the results in Mathematics and Language were identified, thus it was considered pertinent to broaden the knowledge search proposed from the programs. Other studies identified positive impacts on students' trajectories and their household economy; however, these results still need to be strengthened through similar studies in other contexts, which also inquire about the factors that explain these causes. Lastly, future studies should consider the particularities of each program in the search for their effects.

Published: March 2022

This research aims to examine the resilience of the banking industry due to Covid-19. The study focuses on Commercial Banks in Indonesia along January 2017 to April 2021. The study uses a descriptive analysis method of the banking industry in Indonesia with the variables tested including ROA, CAR, LDR, NPL, NIM and BOPO using VAR/VECM analysis. The results show that VECM modelling at the 2nd lag optimum is used at this analysis. Variables that significantly affect banking performance in the short and long run are CAR, LDR, NPL, NIM, BOPO and ROA at 1st lag, but at 2nd lag the LDR variable has no significant effect on ROA in the short run. The shock caused by the variables CAR, LDR, NPL, NIM, BOPO and ROA itself is responded by ROA through the Impulse Response Function and will be corrected to ease moving towards early equilibrium (conditions before the Covid-19 pandemic) within a period of time recovery between 5 months to 30 months. Even though the banking industry is contracting and inefficiency has occurred due to the Covid-19 pandemic, the resilience of the banking industry is still maintained and under control due to the implementation of various stimulus policies issued by the OJK to mitigate banking risks during the Covid-19 pandemic which has the potential issues to financial distress.

The purpose of this research is (1) to propose and address a theoretical framework about the relationship between social entrepreneurship antecedents and students social entrepreneurship competencies (SEC) (For example Empathy, Moral obligation, Self-efficacy, Social support), and (2) to establish the moderating effect of experiential learning (EL) on the relationship between SEA and SEC. Social entrepreneurship is the backbone of empowering both society and economy yielding social welfare and reducing poverty, along with levelling up education quality. Literature indicated that developed countries have given superior attention to the topic of social entrepreneurship due to its crucial role in balancing up social issues such as those in education, environment, health, and businesses and economic stability. Drawing upon the theory of planned behavior (TPB) and experiential learning theory (ELT), the study seeking to apply stratified random sampling and cross-sectional research design for data collection. Students pursuing theirs studies at ENACTUS group universities in China would be the respondents. The study is expected to advance TPB by emphasizing new insights into the importance of EL and students' social entrepreneurial mindset to develop existing social entrepreneurial competencies. In addition, the study provides significant insights for educational managers and professionals about the need to develop social entrepreneurship at educational institutions.
