Authors: Aparna KG , Ravindra Jeshma , Chakraborty Gunimala , Ballamoole Krishna Kumar , Vinaya Kumar JR , Chakraborty Anirban
Published: July 2024

Oral Squamous cell carcinoma (OSCC) is the 14th most frequent cancer with 300,000 new cases and 100,000 deaths reported annually. Even with advanced therapy, the treatment outcomes are poor at advanced stages of the disease. The diagnosis of early OSCC is of paramount clinical value given the high mortality rate associated with the late stages of the disease. Recently, the role of microbiome in the disease manifestation, including oral cancer, has garnered considerable attention. But, to establish the role of bacteria in oral cancer, it is important to determine the differences in the colonization pattern in non-tumour and tumour tissues. In this study, 16S rRNA based metagenomic analyses of 13 tumorous and contralateral anatomically matched normal tissue biopsies, obtained from patients with advanced stage of OSCC were evaluated to understand the correlation between OSCC and oral microbiome. In this study we identified Fusobacterium, Prevotella, Capnocytophaga, Leptotrichia, Peptostreptococcus, Parvimonas and Bacteroidetes as the most significantly enriched taxa in OSCC lesions compared to the non-cancerous tissues. Further, PICRUSt2 analysis unveiled enhanced expression of metabolic pathways associated with L-lysine fermentation, pyruvate fermentation, and isoleucine biosynthesis in those microbes associated with OSCC tissues. These findings provide valuable insights into the distinctive microbial signatures associated with OSCC, offering potential biomarkers and metabolic pathways underlying OSCC pathogenesis. While our focus has primarily centred on microbial signatures, it is essential to recognize the pivotal role of host factors such as immune responses, genetic predisposition, and the oral microenvironment in shaping OSCC development and microbiome composition.

Cultura digital, autoficción, género y precariedad en «El entusiasmo» de Remedios Zafra
Authors: Gómez-García Iván
Published: July 2024

La escritora Remedios Zafra se ha convertido en un referente de los estudios sobre cultura digital en España. Zafra ha indagado en diferentes textos sobre cómo la identidad personal se ha visto moldeada y modificada por el impacto de la digitalización de nuestros entornos cotidianos, tanto de ocio como laborales, y lo ha hecho potenciando la perspectiva de género. Para personalizar la experiencia de la precariedad Zafra inventa una suerte de doble autoficcional (de nombre Sibila) en su obra El entusiasmo: precariedad y trabajo creativo en la era digital (2017). La voz de la ensayista y la conciencia de Sibila se van entrelazando a lo largo de un texto que contextualiza y disecciona esa precariedad a través de herramientas complementarias que provienen de la sociología, la economía y los estudios de género. El propósito del artículo es analizar críticamente los mecanismos de esta doble precarización desde una perspectiva que integre herramientas complementarias a las utilizadas por Zafra. Para ello recurriremos también a otras obras de la autora, como Netianas (2005), Un cuarto propio conectado (2010), (h)adas: mujeres que crean, programan, prosumen, teclean (2013) y el más reciente Frágiles (2021), así como a las ideas de otros autores que han explorado el fuerte componente desmaterializador que tiene la tecnología digital, como Paul Mason (2016) o Éric Sadin (2018), y los riesgos que supone para el desarrollo del sujeto.

Authors: Yang Jie , Huang Yuting , Cui Zhimin , Liu Chang , Xie Guofang
Published: July 2024

Background: Pulmonary fibrosis (PF) is a chronic, progressive, and irreversible heterogeneous disease of lung interstitial tissue. To combat progression of PF, new drugs are required to be developed. Rhizoma coptidis (COP), one of the main alkaloids of Coptis chinensis, is a traditional herbal medicine used to treat various inflammatory diseases.
Objective: To investigate the possible effects of Coptisine (Cop) on the growth, inflammation, as well as FMT of TNF-β1-induced HFL1 cells and uncover the mechanism.
Material and Methods: Human fetal lung fibroblast 1 (HFL1) was induced using 6ng/mL TGF-β1 as a model of pulmonary fibrosis. CCK-8, Brdu, and transwell assays indicated the effects on cell growth as well as motility. qPCR and the corresponding kits indicted the effects on cell inflammation. Immunoblot showed the effects on FMT and further confirmed the mechanism.
Results: Coptisine inhibits excessive growth as well as motility of TNF-β1-induced HFL1 cells. It further inhibits inflammation and ROS levels in TNF-β1-induced HFL1 cells. Coptisine inhibits the FMT process of TNF-β1-induced HFL1 cells. Mechanically, coptisine promotes the Nrf2/HO-1 pathway.
Conclusion: Coptisine can inhibit the excessive growth, inflammation as well as FMT of lung fibroblasts into myofibroblasts. It could serve as a promising drug of PF.

Authors: Yu Zhihua , Sun Zehao
Published: July 2024

This paper briefly introduces plant extracts and their combinations with sports drinks. The research involved 40 sportsmen who are affiliated with the Track and Field Department of the School of Physical Education in South-Central Minzu University. This paper aimed to explore the influence of sports drinks enhanced with extracts of Codonopsis pilosula and Acanthopanax senticosus on the endurance levels of long-distance runners. The participants were divided into four groups: a placebo group, a group receiving only C. pilosula, a group receiving A. senticosus, and a composite group. Endurance performance indices for long-distance running were evaluated both before and after the training. Before training, the heart rate, blood lactate level, and maximum oxygen uptake of the placebo group were 159.53 ± 2.21 times/min, 9.7 ± 1.2 mmol/L, and 66.18 ± 2.35 mL/kg/min, respectively; the single Codonopsis pilosula group was 158.33 ± 2.24 times/min, 9.6 ± 1.1 mmol/L, and 65.87 ± 1.88 mL/kg/min, respectively; the single Acanthopanax senticosus group was 159.66 ± 3.67 times/min, 9.7 ±1.0 mmol/L, and 66.32 ± 1.47 mL/kg/min, respectively; the Codonopsis pilosulae and Acanthopanax senticosus composite group was 158.21 ± 1.28 times/min, 9.6 ± 0.9 mmol/L, and 66.87 ± 1.12 mL/kg/min, respectively. After training, the corresponding values of the placebo group were 162.53 ± 3.21 times/min, 9.6 ± 0.8 mmol/L, and 68.85 ± 3.25 mL/kg/min, respectively; the single Codonopsis pilosula group was 145.33 ± 2.25 times/min, 9.1 ± 0.5 mmol/L, and 73.69 ± 2.58 mL/kg/min, respectively; the single Acanthopanax senticosus group was 142.66 ± 3.69 times/min, 9.1 ± 0.8 mmol/L, and 73.84 ± 2.19 mL/kg/min, respectively; the composite group was 131.21 ± 1.36 times/min, 8.3 ± 0.3 mmol/L, and 77.19 ± 3.14 mL/kg/min, respectively. Sports drinks that include extracts of C. pilosula and A. senticosus significantly increased endurance levels. The concurrent use of C. pilosula and A. senticosus was more beneficial in enhancing endurance performance for long-distance running in comparison to using each extract individually.

Published: July 2024

Mulberry or Morus alba fruits, belonging to the Moraceae family, are well recognized for their distinct taste and high nutritional content. Nevertheless, studies revealing the toxic effects of fruits are scanty. This study aimed to examine the adverse effects of methanolic fruit extract (MFME) derived from M. alba on mice following OECD 425 guidelines. The female Swiss albino mice were divided into two distinct categories. One group was designated as the control group (administered vehicle), while the other was assigned as the test group (administered 2000 mg/kg MFME orally). Subsequently, behavioral changes were monitored daily, and body weights, relative organ weights, and biochemical and hematological parameters were measured. Additionally, liver, kidney, heart, brain, and ovary assessments were conducted on the 14th day to detect any signs of toxicity. A histopathological investigation was conducted on the anesthetized animals’ vital organs (heart, liver, kidney, brain, and ovary). The study’s findings indicate that the oral administration of MFME did not result in any mortality. Additionally, no significant changes were seen in behavior, food and water intake, biochemical parameters, hematological investigations, and organ weights. Furthermore, the histological analysis revealed no notable pathological alterations in the separated essential organs of mice treated with MFME. The results of this study indicate that the oral administration of MFME is deemed safe up to the maximum test dosage of 2000 mg/kg.
Resource inadequacy as a barrier to effective curriculum implementation by life sciences teachers in South Africa
Authors: Chuene Dayce Makakole , Teane Florah Moleko
Published: July 2024

South African teachers experience challenges with the implementation of the national school curriculum – the Curriculum and Assessment Policy Statement (CAPS). In this regard, teachers may not feel empowered to effectively deal with the demands of the current educational policy. Concerns have been expressed about learners’ poor performance in schools and the school infrastructure coupled with educational capacity emerged to be a possible contributing factor. In the study reported on here we focused on the challenges experienced by South African life sciences teachers in the implementation of CAPS caused by limited resources. The context of the study was secondary schools in 1 sub-district in the Northwest province that offered life sciences (LS) in Grades 10 to 12. A qualitative research approach was followed and 10 teachers from rural public schools who taught LS in Grades 10 to 12 during the period of this study were purposefully selected. For data generation, we used audio recordings from individual and focus-group interviews. The findings indicate that teachers’ needs in terms of resources to effectively implement CAPS are often not catered for. It is recommended that adequate teaching and learning resources for effective implementation of CAPS should be provided. The Department of Education’s prioritisation of teachers’ needs will engender effective curriculum implementation.
“Nature is All Personal”: St Francis of Assisi in the Ontology of Mikhail Prishvin
Authors: Medvedev Aleksandr
Published: July 2024

This article analyses Franciscan ideas in the work of M. Prishvin from 1908–1953 in the context of European and Russian Francisciana of the Silver Age. The texts reveal direct and hidden references to the image of St Francis of Assisi and Franciscan texts (The Canticle of Brother Sun and Vita Prima by Thomas of Celano, and Little Flowers of St Francis). It is shown that Franciscan texts become a source of direct, ontological, and personalistic experience of the world as a beautiful and miraculous integrity for Prishvin, creating a paradisiacal harmony between man and creation. St Francis’ compassion for nature became one of Prishvin’s creative impulses in Ginseng (1933) and The Golden Horn (1934). The Franciscan experience of nature in its living reality and personalist uniqueness (nature as subject, not object) is one of the main sources of “kindred (merciful) attention”, Prishvin’s main ontological and life-creating principle. Prishvin polemicised against the opposite of Franciscanism, the utilitarian, object-oriented attitude towards nature in Soviet practice, in which the living, ontological, and personal reality of nature was perceived as an object and replaced by a “patriotic” and utilitarian ideology. In the 1940s, Prishvin returned to the cultural myth of St Francis as a renaissance figure, which emerged in the Russian religious and philosophical renaissance at the turn of the twentieth century; in this myth, St Francis, through his acceptance and justification of the world as God’s creation, overcomes medieval ascetic dualism (matter as evil, the gap between flesh and pirit) and expresses humanistic values (personalism and ontologism), thus uniting God and the world, Christianity and nature, Christianity and culture. For Prishvin’s concept of the integrity of being (the unity of the earthly and the heavenly, the flesh and the spirit), St Francis becomes one of the main sources. What also makes Prishvin similar to St Francis is the concept of joy, which the writer experiences ontologically as the essential basis of being. The image of St Francis becomes not only a literary but also an existential, ontological and creative response of the writer to the challenges of his time. Summing up his life, Prishvin defines his life-creative strategy and mission in the tragic twentieth century in the spirit of St Francis (‘life is happiness’).

Palynology, a prominent field in plant systematics and biodiversity studies, plays a vital role in identifying and determining the plant species present in a specific region. The current study was performed to evaluate the micromorphological traits of pollen from flora of Lesser Himalaya. Pollen microstructural variations aid in the identification of species belonging to specific botanical families and various geographic habitats. Flowers of 24 selected species categorized into 16 families were collected, preserved and then acetolysis protocol followed. Pollen was examined under a light and scanning microscopy (LM and SEM) for palynomorph description. The palynomorphs characteristics such as size, shape, exine surface, and aperture orientation, were examined. Status of these plants show that herbs are being dominant (11 species), while shrubs (7 species), climbers (3 species), bulbous plants (2 species), small tree, sedge, weed (1 species each).  Pollen shape determined in equatorial view were; spheroidal, sub-prolate, oblate-spheroidal, prolate, spherical and sub-oblate. The variations were seen among pollen types; tricolpate, tricolporate and polyporate in most of the species. Exine stratification was observed mostly scabrate while echinate, cristate-reticulate, granulate, punctate, rugulate-perforate, striate-rugulate, verrucate, cristate-foveolate was visualized in each different species. Palynomorph apertural patterns were observed sunken, furrowed, slightly bulged, scabrate, granulate, slit like, and perforate. The largest polar diameter was measured in Hymenocallis littoralis (138.6 µm) whereas smallest in Parthenium hysterophorus (14.70 µm). Equatorial distance was calculated maximum for Cascabela thevetia (110.1 µm) and minimum for Hibiscus rosa-sinensis (1.7 µm). P/E ratio was calculated largest in Hymenocallis littoralis (1.8) and lowest in Duranta erecta (0.89). The palynomorphs taxonomic characters investigated can be helpful in species level identification and provide a baseline to conduct more systematic research with respect to specific plant families and genera.

Macronutrients are essential for plant growth and development because they give plants the building blocks, they need to stay healthy and do important biological processes. A completely randomized designed (CRD) pot experiment was done to find out how nitrogen and sulfur affected the morphology and biochemistry of sunflowers. There were three replicates of each treatment: N1 (0), N2 20 kg ha-1 and N3 40 kg ha-1 and sulfur S1 (0), S2 40 kg ha-1 and S3 60 kg ha-1. Sunflower growth and physiology were improved by exogenously applied sulfur and nitrogen to the plant. Root and shoot length, fresh and dry weight, number of leaves per plant, leaf area, plant height, chlorophyll a, chlorophyll b, carotenoids, total soluble protein, and shoot calcium, potassium, and sodium ions contents all went up compared to the control conditions. Furthermore, sulfur and nitrogen have positive impacts on sunflowers' growth, ionic parameters and there was increase for anthocyanin (24.98%. and 36.66%), ascorbic acid (43.17% and 97.88%), and flavonoid (34.56%. and 112.91%) amounts with the highest levels at 60 kg ha-1 of S and 40 kg ha-1 of N, respectively. There was significant increase in photosynthetic pigments on application of Sulphur (Chl a. :19.15%, Chl b.  52.17%) and Nitrogen (chla. 20.53%, Chl b. 57.16%). Thus, applying sulfur and nitrogen externally to the plant is suggested to boost sunflower growth and chlorophyll levels at different nutritional levels.

Published: July 2024

The Internet of Things (IoT) has emerged as a cornerstone technology, transforming how we interact with our surroundings. Despite their widespread adoption, IoT devices encounter challenges related to processing capabilities and connectivity, frequently necessitating the delegation of tasks to remote cloud servers. This offloading, essential for enhancing user experience, poses challenges, particularly for latency-sensitive applications. Edge-centric paradigms like fog and mist computing have emerged to address these challenges, bringing computational resources closer to end-users. However, efficiently managing task offloading in dynamic IoT environments remains a complex issue. This paper introduces DIstributed COmputing for MIST (dicomist), a methodology designed to facilitate task offloading in IoT settings. Dicomist utilizes wireless mesh networks to organize mobile nodes, employing clustering and classification techniques. Tasks are treated as consensus problems, enabling distributed computation among selected nodes. Real-world experiments demonstrate dicomist’s effectiveness, underscoring its potential to enhance task offloading in IoT environments.

Published: July 2024

Resumen La presente investigación tiene que ver con las contradicciones dialécticas y su relación con el aprendizaje de saberes geométricos en la formación inicial de profesores de matemáticas. En particular, analizamos la manera en que un futuro profesor y el formador enfrentan una contradicción de este tipo, mientras resuelven colectivamente un problema de construcción con GeoGebra, y ofrecemos una explicación de cómo lo anterior contribuye al aprendizaje de la geometría movilizada en la actividad. Para ello, nos posicionamos en una perspectiva educativa histórico-cultural para analizar un episodio en que un futuro profesor y el formador dialogan sobre la respuesta al problema de construir un triángulo isósceles con GeoGebra. Este análisis se realizó en dos etapas para captar el movimiento de ascenso de lo abstracto a lo concreto del objeto de estudio. Los resultados incluyen la descripción de tres acciones formativas que aportan información del modo en que surgió y se enfrentó una contradicción conceptual, y una explicación de cómo esto contribuyó al aprendizaje del saber movilizado. Concluimos que la manera en que la contradicción fue enfrentada por los participantes favoreció la toma de conciencia del saber y permitió la ruptura de la relación práctico-utilitarista que el futuro profesor mantuvo con la tarea.

UPDATE OF PETROPHYSICAL AND GEOLOGICAL MODEL OF MIDDLE JURASSIC DEPOSITS DURING WELL MONITORING
Authors: Gabdullina G.T. , Suleimanov E.D. , Kararova A.Z. , Fakhrutdinova A.M.
Published: July 2024

Tyumen deposits of the studied subsoil area of Western Siberia were put into operation from the middle of the last century, but active development of the YuS2 formation began not so long ago. Currently, the share of wells planned for the operation of this target in the coming years is growing. There are cases when the well performance does not meet the forecasts, which calls into question the correctness of the model used in the development of the target and the structure of the section itself.For high-quality planning of the production stock, it is necessary to prepare a reliable geological basis. The problem of updating the model and improving its reliability lies in the complex geological structure of the formation, which is characterized by high lateral and vertical heterogeneity, as well as in the absence of the basis for all geological models - seismic studies of the investigated subsoil area.The cross-section of the YuS2 reservoirs is complex for petrophysical and geological modeling and is characterized by low reservoir properties. The reservoirs are represented by thin interbeds of permeable interlayers and impermeable clay, carbonaceous and dense rocks.The article examines the specifics of building petrophysical models of YuS2 formations during development drilling using all available core and borehole data to detail the deposits of the Tyumen formation. The purpose of the work is to create own dependencies for interpretation of well geophysical survey data taking into account sedimentation conditions.To detail the Jurassic section, a comprehensive analysis of lithological and petrographic studies of core material from the point of view of geology and petrophysics was used.Facies analysis of the Tyumen deposits in the absence of seismic studies 3D acts as the main factor improving the quality of the predictive ability of geological models in support of development drilling. Adaptation of the petrophysical model to modern geological and technical conditions of well drilling is shown.An integrated approach to the study of the Tyumen formation deposits based on facies and petrophysical studies made it possible to improve the quality of the forecast of the distribution of the reservoir of formation YuS2 and obtain a detailed model. This will help optimize the placement of the production stock, as well as identify the prospects for the development of deposits in areas not covered by drilling.
Cabo Delgado in Peace: Memories and Forebodings
Authors: Santimano Sérgio , Israel Paolo
Published: July 2024

In 1996, Mozambican photographer Sérgio Santimano travelled to Cabo Delgado to carry out photographic work, with the objective of documenting the province in a time of peace and renewal. His travels resulted in the exhibition, Cabo Delgado: A Photographic Story about Africa (Cabo Delgado: uma história fotográfica sobre África), which consolidated his international renown. In this photo-essay, we revisit a selection of Santimano's photographs on Cabo Delgado, with the aim of offering an image different from that of devastation and death which has dominated the national and global news since an Islamist insurgency erupted in the province in October 2017. While providing a pathway into memories of Cabo Delgado as a place rich with life, history, culture and individuality, Santimano's photographs also offer eerie forebodings of the present.
The Hijab: Islam, Women and the Politics of Clothing

P. K. Yasser Arafath and G. Arunima (eds), The Hijab: Islam, Women and the Politics of Clothing (New York: Simon & Schuster, 2022), 272 pp., ISBN: 9789392099380 Dedicated to the 'Muslim girls and women protesting for their rights in India and Iran', historians P. K. Yasser Arafath and G. Arunima have compiled a deeply engaging collection of essays that explore the wearing of the hijab from a multitude of perspectives. The contributions traverse different national contexts and explore multiple and entangled strands of the debates around the hijab, underscoring its breadth and complexity. And as the essays in The Hijab: Islam, Women and the Politics of Clothing demonstrate, not only is this is a complex debate, but also one on very rugged terrain. To dispel misconceptions, prejudices and generalities that abound on the subject, the contributors gathered here come with expertise, variously, in religious studies, sociology, English literature, law, theatre, liberal studies, political science, development studies, journalism, education and historical studies. The essays are grouped into sections - 'Context and Questions', 'Reading the Ban', 'Ethno/History/Life Writing' and 'Many Feminisms' - and read together illuminate the cross-cutting historical, ethnographical and political trajectories in which the question of the hijab is embedded.
Rabhia
Authors: de Almeida Fernanda Pinto

Lucílio Manjate, Rabhia (Maputo: Alcance, 2019), 139 pp., ISBN: 9789928794338 The growing interest in Mozambican crime fiction since the early 2000's reflects a move to portray underexplored characters, stories and spaces of postcolonial life through the lens of the police procedural. This period has not only seen numerous debates in Mozambique surrounding the purported 'death' of Mozambican literature, but it has coincided with a significant literary shift towards the crime novel. Works such as Mia Couto's Under the Frangipani and Lília Momplé's Neighbours have drawn Anglophone readers and scholars into these conversations.1 Since then, Mozambican writers have continued to expand the boundaries of the crime novel in order to question the status of 'engaged' literature and to offer readers nuanced explorations of the genre alongside that of the country's social inheritances of colonialism, liberation struggle, civil war and ongoing armed conflict.
At Ansha's: Life in the Spirit Mosque of a Healer in Mozambique
Authors: Soulimani Amina Alaoui
Published: July 2024

Daria Trentini, At Ansha's: Life in the Spirit Mosque of a Healer in Mozambique (New Brunswick, New Jersey: Rutgers University Press, 2021), 246 pp., ISBN: 9781978806696 At Ansha's is a world that speaks for itself, a place-based ethnography that travels in and out of binaries of extension - spatial and idiomatic antonyms that converge in the making of history and the human. Trentini locates her main protagonist, Ansha, as a migrant from Mueda, Cabo Delgado in Nampula, and offers a rich descriptive landscape that tells many stories; notably, Ansha's passage from being under the control of majini (spirits) to becoming a healer - a transition from illness to healing. The ethnography, through Ansha's memory, is situated at the conjuncture of Mozambique's socialist era, FRELIMO and RENAMO's confrontation, and the anti-colonial war. It recognises the aftermath of dispossession and state violence as an open wound.
Analysis of hunting bag data of woodpigeon (Columba palumbus L.) in Hungary
Authors: Sárközy Áron , Jánoska Ferenc , Sándor Gyula , Bende Attila
Published: July 2024

The European population of the Woodpigeon has increased significantly over the last two decades. In line with this trend, a significant increase has been observed in the Hungarian population since 2006, and in parallel, the hunting bag data of the species has also started to increase. With the increasing hunting bag data, the national centre point of bagging has not changed, so 67.9% of the Hungarian bagging recorded between 1995 and 2022 takes place in Pest, Jász-Nagykun-Szolnok, Bács-Kiskun, and Csongrád-Csanád counties. In order to reduce the increasing damage to agriculture caused by the growing populations of the species, out-of-season bagging of the Woodpigeon was first authorised in Hungary in 2014, and was requested by the game management units from the regional hunting authorities. Out-of-season Woodpigeon baggings accounted for 10% of annual hunting bags by 2022. It is clear that the Woodpigeon population continues to grow even with the current hunting utilisation, and it is also clear that the growing domestic population will become more economically important each year due to the damage caused to agriculture. All this, together with the increasing urbanisation tendency of the species and the change in migration patterns, is creating new challenges for game managers, for which domestic game management must be prepared, despite the fact that the damage caused by the Woodpigeon is not considered as game damage.

Optimized Protocol for RNA Extraction from Insect Samples Using TRIzol Reagent v1
Authors: da Silva Bonjour Monique , de Paula Alves Pinto Ian , José Rinaldi Angelo
Published: July 2024

RNA extraction from insect samples is a crucial step in molecular biology studies aimed at understanding gene expression, functional genomics, and various other applications. This study presents an optimized protocol for RNA extraction from insect tissues using TRIzol reagent. The protocol involves homogenizing insect samples in TRIzol, followed by phase separation with chloroform, RNA precipitation with isopropanol, and washing with ethanol. The final RNA pellet is dissolved in RNase-free water. This method ensures high yield and purity of RNA, suitable for downstream applications such as RT-PCR and RNA sequencing. The efficacy of this protocol was validated through spectrophotometric analysis and agarose gel electrophoresis, demonstrating its reliability and efficiency for extracting RNA from a wide variety of insect species
The Effectiveness of Collaborative Strategic Reading (CSR) in Improving Students’ Reading Comprehension

Published: July 2024

This study was conducted to investigate the effectiveness of Collaborative Strategic Reading (CSR) in enhancing students’ reading comprehension. Pre-experimental research was applied in the form of one group pre-test/post-test design to understand the influence of CSR on the students’ reading comprehension. Study participants included 30 English as a Foreign Language (EFL) students in their second semester of study in the English Department of a West Java private university. This sampling was determined through purposive sampling. The data for the research question of this study was collected through two test instruments - a pre-test and a post-test - with each consisting of 50 questions in each test in the form of multiple choice and observation. Both tests contained questions based on the five indicators of Barrett's taxonomy: literal comprehension, reorganization, inferential comprehension, evaluation, and appreciation. The study applied a gain-score calculation in which the average N-gain score is 61.38. The results showed that the Sig. (2-tailed) value was 0.000 <0.05. Therefore, based on the decision-making criteria, it can be concluded that there is a significant difference between learning outcomes in the pre-test data and post-test data. This means that the implementation of CSR is quite effective in enhancing the students’ reading comprehension competence.

Published: July 2024

Problematic internet use and addiction have grown globally with increased digital access and device usage. Individuals are spending more time online, frequently developing non-adaptive habits and addiction symptoms. This article investigates cyber hygiene’s potential as an effective preventive approach against internet addiction through a cyberpsychology perspective. Cyber hygiene encompasses practices fostering responsible technology use to mitigate risks including internet addiction. A literature review reveals key internet addiction impacts, like mental health issues, social problems, and risky cyberbehaviors. Theoretical analysis evaluates interventions for internet addiction, determining cyber hygiene education has strong potential based on technology addiction models. Results suggest cyber hygiene reduces addiction symptoms by moderating online time, promoting healthy digital habits, and improving self-awareness of technology use. Examined hygiene strategies include monitoring usage, parental controls, and principles like avoiding digital distraction and setting screen time limits. While challenges remain, comprehensive cyber hygiene education combined with multilevel interventions can aid internet addiction prevention and mitigate consequences. The article concludes wide implementation of cyber hygiene education is needed, although additional research on long-term effectiveness is necessary.
