Quantifying the Impact of Risk on Market Volatility and Price: Evidence from the Wholesale Electricity Market in Portugal
Authors: Entezari Negin , Fuinhas José Alberto
Published: March 2024

This research aims to identify suitable procedures for determining the size of risks to predict the tendency of electricity prices to return to their historical average or mean over time. The goal is to quantify the sensitivity of electricity prices to different types of shocks to mitigate price volatility risks that affect Portugal’s energy market. Hourly data from the beginning of January 2016 to December 2021 were used for the analysis. The symmetric and asymmetric GARCH model volatility, as a function of past information, help to eliminate excessive peaks in data fluctuations. The asymmetric model includes additional parameters to separately obtain the impact of positive and negative shocks on volatility. The MSGARCH model is estimated to be in two states, allowing for transitions between low- and high-volatility states. This approach effectively represents the significant impact of shocks in a high-volatility state, indicating an acknowledgment of the lasting effects of extreme events on financial markets. Furthermore, the MSGARCH model is designed to obtain the persistence of shocks during periods of elevated volatility. Accurate price forecasting aids power producers in anticipating potential price trends and allows them to adjust their operations by considering the overall stability and efficiency of the electricity market.
Does Company Information Environment Affect ESG–Financial Performance Relationship? Evidence from European Markets
Authors: Bahadır Oğuzhan , Akarsu Sergen
Published: March 2024

This study investigates the relationship between ESG and financial performance and explores the influence of firms’ information environment on this relationship. To do this, we construct an information environment index from several proxy measures, evaluate ESG performance using Refinitiv’s ESG scores, and evaluate financial performance using return on assets and Tobin’s Q. We find that the information environment index has a positive relationship with both return on assets and Tobin’s Q ratio. On the contrary, ESG has a negative association with return on assets but a statistically insignificant relationship with Tobin’s Q. The negative relationship of ESG with return on assets is convex and weaker in companies with better information environments. We also show that in firms with high asset turnover ratios, ESG does not harm profitability. Separately examining the ESG components reveals that each similarly relates to profitability but that governance has a less negative impact. Our study reveals non-linearities in the relationship between ESG and financial performance that can help companies set better targets and implement better practices about ESG. The moderating effect of the information environment reveals the importance of information dissemination in preventing ESG practices from creating unfavorable consequences. This study may shed light on a more effective ESG policy by showing ways to reduce the adverse financial effects of ESG practices.
The Effect of Electricity Generation on the Performance of Microbial Fuel Cells for Anammox
Authors: Jiang Wenqin , Zhang Jian , Yang Qiulin , Yang Ping
Published: March 2024

The Anammox anaerobic fluidized bed microbial fuel cell (Anammox AFB-MFC) exhibits exceptional performance in both nitrogen removal and electricity generation, effectively eliminating ammonia nitrogen (NH4+-N) and nitrite nitrogen (NO2−-N) pollutants. This technology offers the advantages of high efficiency in nitrogen removal and low electricity consumption. By coupling an AFB with an MFC, the Anammox AFB-MFC was developed through the introduction of anaerobic ammonia-oxidizing bacteria (AnAOB) into MFC. Anammox AFB-MFC’s nitrogen removal ability was found to be superior at an influent COD concentration of 200 mg/L, as determined by a study conducted under unchanged conditions. Subsequently, an open and closed-circuit experiment was performed on the Anammox AFB-MFC system while maintaining a COD concentration of 200 mg/L in the influent. Remarkably, the reactor exhibited significantly enhanced nitrogen removal performance when electricity generation occurred. Throughout the entire experimental process, the reactor consistently maintained high nitrogen removal efficiency and electricity production performance. Under optimal experimental conditions, the reactor achieved a remarkable nitrogen removal rate of 91.8% and an impressive output voltage of 439.1 mV. Additionally, the generation of Anammox bioparticles in MFC significantly contributed to efficient pollutant removal. This study elucidates the impact of organic matter on both the nitrogen removal and electricity generation capabilities of Anammox AFB-MFC, as well as highlights the synergistic effect between MFC electricity generation and nitrogen removal in the reactor.
Modeling Dynamic Bargaining and Stability in a Star-Shaped Trans-Shipment Network
Authors: Peng Shiyong , He Qingren , Xu Fei , Qiu Wanhua
Published: March 2024

The star-shaped trans-shipment network causes the retailer’s bargaining power to be different, which leads to the misalignment of trans-shipment profit. Aimed at this, we take retailers and the trans-shipment paths as the nodes and edges of the trans-shipment network. Based on this, we model the multilateral negotiations between the central retailer and the local retailer and adopt the Generalized Nash Bargaining game to derive the optimal solution of the value function for the incomplete trans-shipment network under the bargaining mechanism. Furthermore, we reveal the convexity of the optimal trans-shipment value function and give the condition that the allocation of the bargaining mechanism is in the core. Based on this, we introduce the concept of pairwise Nash equilibrium and show the star-shaped trans-shipment network is the optimal endogenous formation of the trans-shipment network. In practice, the central retailer should introduce as many local retailers as possible to join this trans-shipment alliance, which will achieve Pareto improvement. Meanwhile, the central retailer should order as many as possible. Finally, it is more appropriate to establish a star-shaped trans-shipment network when one retailer has stronger negotiation power compared to other retailers in a distribution system, which not only ensures the stability of the allocation of trans-shipment profits but also the stability of the trans-shipment network.
Advances in Antiretroviral Therapy for Patients with Human Immunodeficiency Virus-Associated Tuberculosis
Authors: Le Xiaoqin , Shen Yinzhong
Published: March 2024

Tuberculosis is one of the most common opportunistic infections and a prominent cause of death in patients with human immunodeficiency virus (HIV) infection, in spite of near-universal access to antiretroviral therapy (ART) and tuberculosis preventive therapy. For patients with active tuberculosis but not yet receiving ART, starting ART after anti-tuberculosis treatment can complicate clinical management due to drug toxicities, drug–drug interactions and immune reconstitution inflammatory syndrome (IRIS) events. The timing of ART initiation has a crucial impact on treatment outcomes, especially for patients with tuberculous meningitis. The principles of ART in patients with HIV-associated tuberculosis are specific and relatively complex in comparison to patients with other opportunistic infections or cancers. In this review, we summarize the current progress in the timing of ART initiation, ART regimens, drug–drug interactions between anti-tuberculosis and antiretroviral agents, and IRIS.

TREX1 acts in the initial prevention of an autoimmune response, but it may contribute to the permissiveness of retrovirus infections. This study investigated the association between the levels of TREX1 gene expression with the polymorphisms TREX1 rs3135941 (T/C) and TREX1 rs3135945 (G/A), and the presence of antinuclear antibodies (ANA) in antiretroviral therapy (ART)-naïve individuals and after 1 year of treatment. Blood samples from 119 individuals with HIV-1 were subjected to genotyping of polymorphisms and quantification of TREX1 gene expression and HIV-1 viral load by qPCR. The concentration of IFN-α and the number of CD4+/CD8+ T lymphocytes were determined by ELISA and flow cytometry, respectively; ANA was investigated by immunofluorescence. A control group of 167 seronegative individuals was used for the comparison of genotypic frequencies. The frequency of the polymorphisms were not associated with HIV infection or with variations in the expression of TREX1 and IFN-α (p > 0.05). ART-naïve individuals exhibited higher TREX1 expression and lower IFN-α expression. After 1 year of ART, TREX1 levels were reduced, while IFN-α and CD4+ T lymphocytes were elevated (p < 0.05). Some individuals on ART presented ANA. These results suggest that ART-mediated restoration of immune competence is associated with a reduction in TREX1 expression, which may induce the development of ANA, regardless of the polymorphism investigated.
Friends and Foes: The Ambivalent Role of Autophagy in HIV-1 Infection
Authors: Klute Susanne , Sparrer Konstantin M. J.
Published: March 2024

Autophagy has emerged as an integral part of the antiviral innate immune defenses, targeting viruses or their components for lysosomal degradation. Thus, successful viruses, like pandemic human immunodeficiency virus 1 (HIV-1), evolved strategies to counteract or even exploit autophagy for efficient replication. Here, we provide an overview of the intricate interplay between autophagy and HIV-1. We discuss the impact of autophagy on HIV-1 replication and report in detail how HIV-1 manipulates autophagy in infected cells and beyond. We also highlight tissue and cell-type specifics in the interplay between autophagy and HIV-1. In addition, we weigh exogenous modulation of autophagy as a putative double-edged sword against HIV-1 and discuss potential implications for future antiretroviral therapy and curative approaches. Taken together, we consider both antiviral and proviral roles of autophagy to illustrate the ambivalent role of autophagy in HIV-1 pathogenesis and therapy.
Schlafen14 Impairs HIV-1 Expression in a Codon Usage-Dependent Manner
Authors: Valenzuela Carlos , Saucedo Sergio , Llano Manuel
Published: March 2024

Schlafen (SLFN) is a family of proteins upregulated by type I interferons with a regulatory role in translation. Intriguingly, SLFN14 associates with the ribosome and can degrade rRNA, tRNA, and mRNA in vitro, but a role in translation is still unknown. Ribosomes are important regulatory hubs during translation elongation of mRNAs rich in rare codons. Therefore, we evaluated the potential role of SLFN14 in the expression of mRNAs enriched in rare codons, using HIV-1 genes as a model. We found that, in a variety of cell types, including primary immune cells, SLFN14 regulates the expression of HIV-1 and non-viral genes based on their codon adaptation index, a measurement of the synonymous codon usage bias; consequently, SLFN14 inhibits the replication of HIV-1. The potent inhibitory effect of SLFN14 on the expression of the rare codon-rich transcript HIV-1 Gag was minimized by codon optimization. Mechanistically, we found that the endoribonuclease activity of SLFN14 is required, and that ribosomal RNA degradation is involved. Therefore, we propose that SLFN14 impairs the expression of HIV-1 transcripts rich in rare codons, in a catalytic-dependent manner.
Trans-Amplifying RNA: A Journey from Alphavirus Research to Future Vaccines
Authors: Yıldız Ayşegül , Răileanu Cristian , Beissert Tim
Published: March 2024

Replicating RNA, including self-amplifying RNA (saRNA) and trans-amplifying RNA (taRNA), holds great potential for advancing the next generation of RNA-based vaccines. Unlike in vitro transcribed mRNA found in most current RNA vaccines, saRNA or taRNA can be massively replicated within cells in the presence of RNA-amplifying enzymes known as replicases. We recently demonstrated that this property could enhance immune responses with minimal injected RNA amounts. In saRNA-based vaccines, replicase and antigens are encoded on the same mRNA molecule, resulting in very long RNA sequences, which poses significant challenges in production, delivery, and stability. In taRNA-based vaccines, these challenges can be overcome by splitting the replication system into two parts: one that encodes replicase and the other that encodes a short antigen-encoding RNA called transreplicon. Here, we review the identification and use of transreplicon RNA in alphavirus research, with a focus on the development of novel taRNA technology as a state-of-the art vaccine platform. Additionally, we discuss remaining challenges essential to the clinical application and highlight the potential benefits related to the unique properties of this future vaccine platform.

Published: March 2024

Background: Some peptide anticancer vaccines elicit a strong T-cell memory response but fail to suppress tumor growth. To gain insight into tumor resistance, we compared two peptide vaccines, p20 and p30, against B16 melanoma, with both exhibiting good in vitro T-cell responses but different tumor suppression abilities. Methods: We compared activation markers and repertoires of T-lymphocytes from tumor-draining (dLN) and non-draining (ndLN) lymph nodes for the two peptide vaccines. Results: We showed that the p30 vaccine had better tumor control as opposed to p20. p20 vaccine induced better in vitro T-cell responsiveness but failed to suppress tumor growth. Efficient antitumor vaccination is associated with a higher clonality of cytotoxic T-cells (CTLs) in dLNs compared with ndLNs and the convergence of most of the enriched clones. With the inefficient p20 vaccine, the most expanded and converged were clones of the bystander T-cells without an LN preference. Conclusions: Here, we show that the clonality and convergence of the T-cell response are the hallmarks of efficient antitumor vaccination. The high individual and methodological dependencies of these parameters can be avoided by comparing dLNs and ndLNs.

Cameroon introduced the malaria vaccine in its routine immunization program on 22 January 2024 in the 42 districts out of 200 that are among the most at risk of malaria. A cross-sectional analysis of the data on key vaccine events in the introduction roadmap and the vaccine uptake during the first 30 days was conducted. In addition to available gray literature related to the introduction of the malaria vaccine, data on the malaria vaccine uptake by vaccination session, collected through a digital platform, were analyzed. A total of 1893 reports were received from 22 January 2024 to 21 February 2024 from 766 health facilities (84% of overall completeness). Two regions out of ten recorded less than 80% completeness. As of 21 February 2024, 13,811 children had received the first dose of the malaria vaccine, including 7124 girls (51.6%) and 6687 boys (48.4%). In total, 36% of the children were vaccinated through outreach sessions, while 61.5% were vaccinated through sessions in fixed posts. The overall monthly immunization coverage with the first dose was 37%. Early results have shown positive attitudes towards and acceptance of malaria vaccines. Suboptimal completeness of data reporting and a low coverage highlight persistent gaps and challenges in the vaccine rollout.
The Construction of Urban Rainstorm Disaster Event Knowledge Graph Considering Evolutionary Processes
Authors: Zou Yalin , Huang Yi , Wang Yifan , Zhou Fangrong , Xia Yongqi , Shen Zhenhong
Published: March 2024

Rainstorm disasters pose a significant threat to the sustainable development of urban areas, and effectively organizing diverse information sources about them is crucial for emergency management. In light of recent advances in knowledge graph theory and application technology, their notable knowledge integration and representation capabilities may offer support for dynamic monitoring and decision-making processes concerning urban rainstorm disaster events. However, conventional models do not adequately capture the spatiotemporal characteristics of these events. To fill this gap, we analyze the essence of urban rainstorm disaster events and divide their evolution into four stages, namely, pregnant, development, continuous, and decline stages. On this basis, a multilevel knowledge representation model is proposed from four layers, which are event, object–state, feature, and relationship layers, by analyzing the components and dynamic characteristics from the mechanism of urban rainstorm disaster events. The proposed model can not only express the comprehensive structure and relationships within urban rainstorm events, but also emphasize the evolution of disaster events through a series of ordered states. Moreover, we test the utility of the constructed knowledge graph through a case study of the Zhengzhou 720 rainstorm. The case study first validates that the selected machine learning models can extract the urban rainstorm disaster event information accurately by comparing them with some mainstream models. Then, it demonstrates that the knowledge graph is practical in the field of disaster knowledge representation, and disaster condition retrieval. Additionally, since the knowledge graph can show the evolution of a disaster event throughout its full life cycle, it can promote the understanding of the mechanisms of urban rainstorm disasters and pave the way for future applications of disaster prevention and reduction.
Analysis of Changes in Runoff and Sediment Load and Their Attribution in the Kuye River Basin of the Middle Yellow River Based on the Slope Change Ratio of Cumulative Quantity Method
Authors: Zhang Jiankang , Wang Jiping , Zhao Nana , Shi Jiansheng , Wang Yichuan
Published: March 2024

Climate change and human activities exert significant influence on the water–sediment relationship in arid and semi-arid regions. Therefore, comprehending the underlying mechanisms is crucial for the effective management of water and soil resources, as well as integrated watershed management. This research focuses on the Kuye River watershed (KYH_W) in the middle reaches of the Yellow River in China, along with its sub-watersheds Wangdaohengtazi (WDHT_SW) and Xinmiaosi (XM_SW). This paper utilizes the Mann–Kendall non-parametric test and the double cumulative curve method to examine the interannual trends of runoff, sediment transport, precipitation, temperature, and NDVI factors. Furthermore, the method of the slope change ratio of cumulative quantity (SCRCQ) is utilized to quantitatively evaluate the impacts and contribution rates of climate change and human activities on water–sediment changes within each watershed. The results are as follows: (1) From 1969 to 2019, the entire watershed experienced a significant decrease in both runoff and sediment transport, with 1997 marking the year of abrupt change. However, following 2012, the KYH_W and WDHT_SW exhibited a noticeable rebound in runoff. (2) Human activities predominantly contribute to the reduction in water and sediment in the watershed. (3) After the abrupt change, between 1998 and 2011, the contribution rates of climate change and human activities to the annual runoff reduction in the entire KYH_W reached 33% and 64%, respectively. Moreover, these rates for sediment transport reduction reached 26% and 74%, respectively. Subsequently, after 2012, the contribution rates of both factors to the increase in watershed runoff reached 29% and 71%, respectively. Factors other than the NDVI, within human activities, played a dominant role in augmenting the watershed’s runoff. (4) Prior to 2011, changes in vegetation cover resulting from the Grain for Green Program, as measured by the NDVI, emerged as the primary factor responsible for reduced runoff in the watershed. Conversely, factors other than the NDVI assumed dominance in reducing sediment transport. The SCRCQ method offers a quantitative approach to assessing water–sediment changes. Based on this method, the study further underscores the substantial impacts of climate change and human activities on variations in runoff and sediment transport within the KYH_W in the middle reaches of the Yellow River. Notably, the water–sediment changes in the KYH_W exhibit distinct stage-wise and spatial discrepancies, which warrant increased attention in future research endeavors.
Ô droit ! Suspends ton vol ! La protection des rives des lacs de montagne de la théorie juridique à la pratique alpine
Authors: Moulin Sabine
Published: March 2024

La protection juridique des lacs, comme élément de paysage, est, en France, séculaire. Elle a été renforcée en montagne par la

loi du 9 janvier 1985 dite loi «Montagne » et par la loi du 3 janvier 1986 dite loi «Littoral » en fonction de la superficie des lacs. Toutefois, cette protection n’a cessé de s’éroder au fil des modifications législatives.

C’est pourquoi, après avoir rappelé la réglementation d’urbanisme applicable aux lacs et plans d’eau de montagne et son évolution, nous avons souhaité questionner son application d’un point de vue théorique et pratique en examinant notamment sa mise en oeuvre

à différentes échelles spatiales, allant de la planification stratégique des massifs aux autorisations d’occupation des sols. Force est de constater que malgré ses insuffisances d’une part, et sa mise en oeuvre minimaliste et partielle d’autre part, la loi

s’avère indispensable pour protéger les lacs de la multiplicité des projets d’aménagements qui concernent aujourd’hui aussi bien leurs rives que leur surface.
Lacs publics mais rives (en partie) privées : analyse d’un paradoxe géo-légal
Authors: Nikolli Alice
Published: March 2024

Large perialpine lakes belong to the public domain, with slight legal differences in each alpine country. Historical reasons explain this public status, as their use for navigation. In theory, this status ensures free access to the lake, for tourism and recreation among other functions. Building from French, Italian and various Swiss cantons case studies, this paper intertwines the legal status of public lakes and geographical analyses about their uses and empirical access to their shoreline. I argue that the legal regime of public domain constructed the “ lake” object according to a very restrictive spatial delimitation, limited to the water body itself and occasionally expanded to the shores when rights of way are provided. This spatial extent still shrank between the late 19th and the early 20th centuries, owing to the shoreline urbanisation-privatisation process which suppressed some of these rights of way.

Nowadays, social demand for accessing the lakes is strong but hardly satisfied because of the coastal privatisation.

This context challenges the legal construction of the “ lake” as a spatially restrictive object. The public domain

regime is theoretically very protective but this spatially restricted delimitation prevents it from being really efficient

in terms of public access to the lakes. The paper thus proposes to explain this geo-legal paradox.
Les représentations de l’espace lacustre de l’Antiquité à nos jours. Réflexions à partir d’exemples savoyards
Authors: Nieloud-Muller Sébastien
Published: March 2024

Sous le vernis superficiel de l’image du beau lac, miroir d’eau calme et imperturbable, se cache un jeu complexe de représentations. L’examen de dossiers relatifs au domaine savoyard permet de formuler quelques réflexions sur la formation de l’imaginaire attaché aux espaces lacustres au cours du temps. La prise en considération des sources textuelles gréco-latines et des images publicitaires actuelles, en passant par les vestiges de la période romaine, les légendes médiévales et les récits de l’époque moderne, permet de restituer quelques jalons significatifs de l’évolution de ces représentations de l’Antiquité à nos jours. L’ensemble de ces sources montrent que les lacs sont, quelles que soient les époques, attachés au domaine du symbolique et du spirituel. Malgré une meilleure connaissance scientifique de ces espaces, ces conceptions continuent d’alimenter nos propres représentations. D’une manière générale, les lacs restent largement méconnus et ils continuent d’incarner une forme de mystère.

Afet eğitimlerinin hemşirelik öğrencilerinin afet yönetimi algısını olumlu yönde geliştirdiği görülmüştür.
Evaluación de los efectos de la endogamia en la calidad seminal bovina mediante el análisis de bloques de homocigosidad y estudios de asociación de genoma completo
Authors:   , Teran Ester Mercedes
Published: March 2024

La endogamia puede definirse como el apareamiento entre individuos emparentados. Su aumento puede provocar depresión endogámica, que es la disminución de la media fenotípica poblacional de varios caracteres, principalmente los reproductivos. En los últimos años, la utilización de información genómica ha permitido estimar de forma más precisa el nivel de endogamia, mediante la identificación de segmentos homocigotos (runs of homozygosity, ROH) y, en base a ellos poder calcular un coeficiente de endogamia molecular (FROH). En esta tesis se caracterizó la abundancia y distribución de ROH en tres poblaciones bovinas, encontrándose variabilidad, y acumulación de ROH en ciertas regiones en dos razas, las cuales se asociaron con procesos de selección. Particularmente, se observó variabilidad de ROH entre individuos con similares coeficientes de endogamia basados en pedigrí. Además, se evaluó el efecto de la endogamia molecular global, cromosómica y por longitud, sobre la morfometría, motilidad y longevidad espermática, así como las regiones genómicas enriquecidas en ROH asociadas a dichos caracteres. Se encontró que una endogamia mayor a 0,125 provocaba un incremento de espermatozoides pequeños y alargados, y una hiperactivación temprana, la cual podría limitar la longevidad espermática. Las regiones significativamente enriquecidas en ROH incluyeron genes asociados con la espermatogénesis, motilidad, fisiología espermática y el desarrollo embrionario. Se evidenciaron diferentes niveles de depresión endogámica entre los distintos cromosomas, y un mayor efecto debido a ROH largos, originados recientemente. Finalmente, una combinación de ROH y análisis de asociación permitió identificar genes potencialmente involucrados en la longevidad espermática. En conclusión, el uso de FROH es más fiable e informativo que el F basado en pedigrí, y complementado con el análisis funcional es una metodología innovadora para el análisis de depresión endogámica en caracteres productivos. Esta tesis contribuye a aumentar el conocimiento sobre los efectos de la endogamia molecular en la calidad espermática del bovino.

Climate change, in many regions of the world, could intensify the structural development challenges of the education sector and induce education provision, education access, education quality. education financing and education management regression dynamics. The main options for managing these threats of climate change include the development of theoretical and methodological tools to improve the relevance, efficiency and impact of education sector resilience to climate change plans. These plans should be multidimensional, take into account gender and social inclusion issues and achieve planned resilience objectives. This article describes the Badolo EduResilience scientific framework, a scientific tool for strengthening the capacities of education stakeholders to develop and implement efficient response plans to the threats posed by extreme climate events and their impacts.The Badolo EduResilience Scientific Framework is used to generate bodies of knowledge, vulnerability indicators and resilience schemes to model resilience trajectories that achieve education sector planned resilience objectives to extreme climate events. The bodies of knowledge are bodies of extreme events impacts, bodies of vulnerability factors to extreme events and bodies of resilience solutions to extreme events. Resilience objectives are short-term, medium-term and long-term resilience configurations. The Badolo EduResilience scientific framework suggests new practices for the education sector's resilience to extreme climate events. These practices require inclusive, equitable and participatory resilience governance

This study aims to determine whether there is a correlation between English learning motivation and students speaking ability. The research used a quantitative method in correlational research design and statistical tests of IBM SPSS 20 with the Spearman-rank Correlation test formula. After testing both variables, the data shows no relationship between English learning motivation and students speaking ability. The inferential statistical analysis results show that the result of the Spearman-rank Correlation test is valued as much as Sig = 0.224 < 0.05 (there is no correlation) with a correlation coefficient of 0.167. Eventually, the correlation test results between learning motivation and students' speaking ability show that students' speaking ability is not thoroughly influenced by motivation in learning English.

It clarifies the linguistic declarative signification according to the actual meaning, while the suggestive gives the meaning of the poetry in depth. The metaphorical signification is an ideological process of suggestive that serves to provide justification and disclosure of the dominant values ??that apply during a certain time period. The primary data in this scientific research is Poetry To My Mother by Mahmoud Darwish and the secondary sources support books related to scientific research. From the analysis, it is known that the declarative significance is that this poetry indicates the poet's longing for his mother, and the suggestive significance of this poem is the poet's longing for his homeland. Likewise, the influence of Mahmoud Darwish's poetry on the readers made them feel nostalgic in the words about longing for the motherland far from their lives.

Published: March 2024

Project Based Learning (PBL) is a student-centred learning approach in which a teacher acts as a facilitator to help a student solve a problem. In the present study, involvement is a substantial element in PBL because the student is required to learn collaboratively in a group project. Therefore, the study aims to discover how the student is involved in accomplishing scholarly writing in a group project, and what the opportunity of writing a scholarly article collaboratively is. The present research is a case study in a private university in Indonesia. The data are gained from a questionnaire and an interview. The data then are analyzed qualitatively. The study discovers that PBL is believed to activate EFL students’ involvement in terms of contributing to the team project, handling responsibility, and respecting teammates. The opportunities of PBL implementation in writing experienced by the students are getting ideas, designing the project, tunning the project, writing the project, exhibiting the project, and evaluating the project. Finally, the study is expected to provide teachers with practical ideas for implementing PBL effectively in a writing context.
