The Lived Experiences of Alternative Learning System Teachers in English Literacy Instruction
Authors: Francisco Jonathan , Buri Crisanta
Published: September 2024

This study explores the challenges that Alternative Learning System (ALS) teachers face in English literacy instruction and the coping strategies they employ to overcome these hurdles. Given the crucial role of English literacy, this study aims to delve into the lived experiences of ALS teachers, who are pivotal in the knowledge transfer process. Employing a phenomenological approach within qualitative research, the study draws on in-depth, in-person interviews with five ALS teachers to gather rich, experiential data. The thematic analysis of the interview transcripts reveals that ALS teachers' roles encompass physical demands, mental fortitude, emotional investment, and social engagement. The themes that emerge as challenges in teaching the Communication Skills strand in English include high demands on teachers' resilience, diversity of students, limited instructional materials, limited instructional time, and negative public perception of teachers' roles and the program. Despite these challenges, ALS teachers develop coping strategies, including cultivating resilience to manage the demands of teaching the strand and maintaining a positive outlook. This study concludes that while ALS teachers face significant obstacles in managing the learning strand, their effective use of specific coping strategies ensures that each learner receives appropriately leveled instruction. Based on the findings, the researcher proposes a training program that can improve ALS teachers' pedagogical approaches to enhance further their capabilities in making a difference in the field of education through ALS and, most importantly, in the lives of their learners.
Gendered Language in Philippine Newspapers
Authors: Java Almar
Published: September 2024

Print media can influence public perceptions but may also reinforce gender bias through language. Numerous studies have underscored the persistence of linguistic sexism in print publications, highlighting how language choices can reinforce gender stereotypes and inequality. This study investigates gendered language in The Philippine Daily Inquirer, a leading newspaper in the Philippines, to highlight how sexist terms persist in modern print media. The study analyzed the May 2018 issue using quantitative and qualitative content analysis, focusing on terms influenced by Gender Schema Theory and Social Responsibility Theory. Five gendered terms with sexist undertones were identified: "policemen," "businessman," "countrymen," "gunmen," and "ombudsman," with "policemen" being the most common. These terms were grouped into three categories: Generic Masculine, Derogatory, and Pseudo-Masculine expressions, with Generic Masculine terms being the most prevalent. The findings show that print media continues to use sexist language, particularly through Generic Masculine terms. The study suggests a thorough content review in media outlets to remove sexist language and encourage gender-neutral alternatives.
Moderating Effect of Demographic Profile on Employee Engagement and Productivity
Authors: Belostrino Maria Regina , Estiller Renalyn
Published: September 2024

This study explores the moderating effect of demographic profile on employee engagement and productivity in Cavite, Philippines. The study focused on the 321 service crews working in the Quick Service Restaurants (QSRs), who were selected through a simple random technique. The findings show that productivity is negatively impacted by physical engagement. This suggests an effect between more customer complaints and less physical engagement. Accuracy and quality are affected by emotional engagement, indicating that a drop in emotional engagement could result in a drop in quality. Other types of engagement, such as trait, behavioral, psychological, and cognitive, do not affect productivity. The results are consistent with earlier studies, emphasizing the role that engagement dimensions, including physical, emotional, cognitive, trait, psychological state, and behavioral, play in raising productivity in the service industry. The study also emphasizes how important demographic characteristics are in determining how engagement and productivity are related. Gender does not significantly attenuate this association; nevertheless, other demographic factors that are important to consider are age, marital status, duration of service, and monthly wage. Theoretical implications imply that, in contrast to conventional wisdom, gender may not significantly impact employee productivity in QSRs. In practical terms, the non-significant gender moderation effect highlights how crucial it is to implement gender-neutral engagement tactics to raise worker productivity and levels of engagement. The study suggests future paths for research and offers useful implications for organizational management.

Nervous System, Neurons, and Metabolism
Authors: Konukoglu Dildar
Published: September 2024

Alzheimer’s disease (AD) is a neurodegenerative disorder that leads to cognitive decline and is the most common form of dementia in the elderly. Neurons, as the primary cells of the central nervous system, are fundamental to brain function. Understanding their structure and functions is crucial for grasping AD mechanisms.

Neurons consist of three main components: the cell body (soma), dendrites, and axon. The cell body is the metabolic center of the neuron, containing the nucleus and organelles. Dendrites receive signals from other neurons, while axons transmit these signals to other neurons or muscle cells. Synaptic terminals at the end of axons release neurotransmitters, facilitating communication between neurons.

Neuronal metabolic activities include energy production, protein synthesis, and intracellular transport. Mitochondria play a crucial role in energy production, and mitochondrial dysfunction is a significant factor in AD. Reduced energy production adversely affects neuronal functionality and survival. In conclusion, the structure and metabolic processes of neurons play a critical role in the pathogenesis of AD. The disruption of neuronal structures and functions leads to the clinical manifestations of AD. Therefore, protecting neurons and supporting their functions are crucial targets in the treatment of AD.The initial part of the book provides an essential understanding of neuron biology, focusing on their functions and energy metabolism. The section examines the structural characteristics of neurons and their roles in neural communication. The chapter emphasizes efficient metabolic pathways, detailing glycolysis, oxidative phosphorylation, and ATP generation, and highlights the critical dependence of neuronal function on a continuous and sufficient energy supply.
Alzheimer’s Disease and Obesity
Authors: Ilhan Nevin , Susam Solmaz
Published: September 2024

Research has highlighted the role of adipokines, signaling molecules secreted by adipose tissue, in both metabolic dysregulation associated with obesity and the neurodegenerative processes underlying AD. Key adipokines include leptin, which has neuroprotective effects, adiponectin, which has anti-inflammatory and insulin-sensitizing properties, and resistin, which is implicated in insulin resistance and may contribute to neuroinflammation and cognitive decline. Understanding the interplay between obesity, adipokines, and AD is crucial for identifying novel therapeutic strategies targeting both metabolic and cognitive impairments. This chapter aims to elucidate the relationship between AD and obesity, with a focus on selected adipokines that play pivotal roles in obesity-related pathophysiological mechanisms and neuroinflammation. Another critical pathological feature of AD is the formation of neurofibrillary tangles (NFTs), produced by hyperphosphorylated tau. In summary, The chapter shows the connections between obesity, adipokines, and AD highlights shared pathophysiological mechanisms.
Relationship Between Dyslipidemia and Alzheimer’s Disease
Authors: Bolayirli Ibrahim Murat , Kucur Mine
Published: September 2024

Dyslipidemia may affect AD development through mechanisms involving ApoE4 levels, neuroinflammation, oxidative stress, cholesterol interactions with amyloid plaques and synaptic function, and vascular components. Increased cholesterol levels alter the blood-brain barrier’s permeability, potentially contributing to AD. ApoE, particularly its ε4 allele, is a significant genetic risk factor for AD. ApoE is involved in lipid transport and neural repair, with isoforms affecting AD pathology differently. ApoE4 is less effective in lipidation and promotes Aβ aggregation, reducing clearance and increasing deposition. This leads to neuroinflammation, tau hyperphosphorylation, and synaptic dysfunction. Cholesterol’s role in AD is linked to its influence on membrane properties, synaptic function, and Aβ production. High cholesterol levels can exacerbate Aβ generation and disrupt synaptic processes. Targeting these processes, along with managing dyslipidemia, offers potential pathways for mitigating AD progression.
Alzheimer’s Disease and Dementia: Epidemiology, Social and Economic Challenge
Authors: Boz Canser , Mete Ani Hande
Published: September 2024

Alzheimer’s disease (AD) is a progressive neurodegenerative disorder that primarily affects the elderly, leading to severe cognitive decline and memory loss. The global prevalence of Alzheimer’s is rising rapidly due to increasing life expectancy and an aging population. As of 2023, it is estimated that over 50 million people worldwide are living with Alzheimer’s disease. The socioeconomic burden of Alzheimer’s disease is immense, encompassing direct medical costs, indirect costs, and the emotional toll on patients and their families. Direct medical costs include expenses for diagnosis, treatment, and long-term care. These costs are substantial because Alzheimer’s patients often require continuous care, including home care services, assisted living, and nursing home care. The indirect costs primarily involve lost productivity, both from patients who can no longer work and from caregivers who may reduce their working hours or leave their jobs to provide care. The emotional and psychological burden on caregivers is also significant. Family members and friends who provide care often experience high levels of stress, depression, and physical health issues. The time-intensive nature of caregiving can strain personal relationships and reduce the quality of life for both caregivers and patients. Efforts to address the socioeconomic impact of Alzheimer’s disease involve a multifaceted approach, including advancing research for early diagnosis and treatment, improving care facilities, and providing support systems for caregivers. Public health strategies also emphasize the importance of lifestyle changes and preventive measures that may reduce the risk of developing Alzheimer’s. The section provides a comprehensive overview of Alzheimer’s Disease, beginning with its epidemiology, and examining the social and economic challenges.. The section examines demographic shifts, such as aging populations, that increase Alzheimer’s prevalence and considers the implications for public policy and resource allocation for care. This part of the book also examines the social and economic challenges posed by Alzheimer’s Disease, and the direct and indirect costs associated with the disease, including medical care, lost productivity, and the emotional and financial impact on caregivers.

Authors: Kaya Gulec Zeynep Ece , Bozluolcay Melda
Published: September 2024

This chapter delves into the diagnostic process of Alzheimer’s disease, emphasizing the various limitations and challenges in achieving accurate diagnoses. It begins by reviewing the traditional diagnostic criteria, which typically include clinical assessments, cognitive tests, and evaluation of medical history. These methods, while foundational, often present challenges in distinguishing Alzheimer’s from other forms of dementia, especially in the early stages of the disease. The section then explores the latest advancements in clinical assessment tools that have significantly enhanced diagnostic accuracy. Neuroimaging technologies such as Magnetic Resonance Imaging (MRI) and Positron Emission Tomography (PET) scans are highlighted for their ability to detect structural and functional changes in the brain associated with Alzheimer’s. MRI scans provide detailed images of brain anatomy, allowing for the identification of atrophy in specific brain regions, while PET scans can measure metabolic activity and detect amyloid plaques and tau tangles, which are hallmark features of Alzheimer’s pathology. In summary, this chapter provides a comprehensive overview of the diagnostic process for Alzheimer’s disease, highlighting both traditional methods and cutting-edge advancements. It underscores the importance of integrating multiple diagnostic tools to improve accuracy and discusses how recent discoveries in genomics are paving the way for early detection and personalized medicine in the fight against Alzheimer’s.

Published: September 2024

This section provides practical knowledge about the molecular structures, clinical use conditions, and laboratory applications of biomarkers, focusing on those currently in use, soon to be used, and those with high potential. Main biomarkers for AD diagnosis include Aβ fragments, tau protein forms, neurofilament light chain (NfL), glial fibrillary acidic protein (GFAP), and alpha-synuclein (αSyn). Aβ fragments, central to AD pathology, are released by the cleavage of amyloid-beta precursor protein (APP). They form amyloid plaques and can be detected in cerebrospinal fluid (CSF) and plasma, with specific ratios aiding in diagnosis. Tau proteins, particularly phosphorylated tau (p-tau) and total tau (t-tau), reflect neurofibrillary tangles and neurodegeneration. NfL, a marker of axonal damage, and GFAP, indicative of reactive astrogliosis, are measured in CSF and blood. αSyn, associated with synucleinopathies, forms aggregates detectable in biological samples. Detection methods include conventional immunodetection techniques like ELISA, ultrasensitive technologies like SIMOA, and amyloid seed amplification assays (SAA). These methods enable the accurate measurement of biomarkers, enhancing early diagnosis and monitoring of AD.

In this paper, we present a mathematical model describing the dynamics of Helicobacter pylori population in the presence of 〖CO〗_2 and the immune system. We analyze the mathematical and biological meaningful of the model. We analyze the equilibrium of the model. This analysis shows the presence of two types of equilibrium. The first one occurs in the absence of the immune response and when there is no 〖CO〗_2 in the stomach, called “disease-free equilibrium”. The second equilibriums, called “endemic equilibriums”, occur in the presence of immune response and when the concentration of 〖CO〗_2 is not null. The numerical simulation shows that with good alimentary behaviors, the disease-free equilibrium point can be reached. MSC 2000, 34D15, 34D23, 92D25, 37B55

In the present study, zinc oxide nanoparticles were prepared using the aqueous extract of the leaves of Chromolaena odorata. These biosynthesized nanocrystals were characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), X-ray energy dispersive spectroscopy (EDS), scanning electron microscopy (SEM) and transmission electron microscopy (TEM). XRD results on the prepared powder confirmed the presence of ZnO, with an estimated mean size of 24 nm. The SEM and TEM images indicated that the synthesized nanoparticles were spherical in shape with good particle dispersion. FTIR spectroscopy also confirmed the presence of ZnO in the synthesized powder through to the presence of the band localized between 800-500 cm-1, which is characteristic of the (Zn−O) bonds in zinc oxide. The antimicrobial activity of the prepared nanopowders against the bacterial strains E. coli and S. aureus demonstrated significant inhibitory effects. These inhibitory effects were more pronounced on E. coli than on S. aureus with maximum inhibition zones of 16 and 14 mm, respectively. It appears that this method can be used for the rapid and environmentally-friendly biosynthesis of stable zinc oxide nanoparticles having antimicrobial properties.

The understanding of meteorological parameters influencing rainfall is essential to effectively address environmental challenges and anticipate the consequences of extreme weather events. In this study, we analyze meteorological data provided by the Airways Authority of Kinshasa (RVA), covering the period from 1992 to 2019. This in-depth statistical analysis aims to better understand the factors that influence precipitation in the region and to identify relevant climate trends for anticipating future environmental changes. We used logistic regression to assess the impact of various climatic factors such as temperature (daily extremes), relative humidity, and atmospheric pressure on precipitation. The results indicate that minimum temperature, relative humidity, and atmospheric pressure show a strong correlation with rainfall in Kinshasa, highlighting their significant influence on the likelihood of precipitation. In contrast, maximum temperature has a limited impact, making it a less reliable indicator of rainfall in the city. The conclusions of this study provide valuable tools for local authorities in developing effective strategies for managing climate variations and predicting weather phenomena. These insights enable precise modeling of the impacts of meteorological fluctuations on ecosystems and urban infrastructure. Furthermore, the results of this research can guide local farmers in optimizing their agricultural practices by adjusting planting and harvesting schedules based on detailed weather forecasts, thereby minimizing economic losses and enhancing crop resilience to climate variations. Finally, this study provides climatologists with robust data for in-depth analysis of the effects of climate change on meteorological phenomena in Kinshasa. This knowledge is crucial for refining regional climate models and developing specific adaptation strategies for other urban areas in sub-Saharan Africa.

Philippe Vilain ou le parti-pris de la forme
Authors: Hoffmann Benjamin
Published: September 2024

Le travail critique de Philippe Vilain manifeste une enthousiasmante créativité conceptuelle par sa capacité à saisir les recompositions de la littérature française des vingt dernières années au moyen de termes et de néologismes qu’il prend grand soin à définir et illustrer. Cet article propose une réflexion sur les principaux éléments du langage théorique forgé dans La Littérature sans idéal (2016) et La Passion d’Orphée (2020) afin de contribuer à une définition des thèses vilainiennes au sujet de la production littéraire contemporaine. À l’instar de tout langage, celui que déploient les essais de Philippe Vilain véhicule une série de valeurs sous-jacentes dotées d’un rôle structurant, les plus déterminantes d’entre elles étant la sacralité de la langue et le parti pris de la forme.
« Le noeud gordien de ma propre entreprise » L’autofiction selon Philippe Vilain
Authors: Baudelle Yves
Published: September 2024

Philippe Vilain est l’un des rares écrivains à désigner l’autofiction comme son genre de prédilection et, de surcroît, à souscrire dans ses essais à la conception la plus restreinte du genre, celle de Doubrovsky, qui conjugue fiction et homonymat (l’auteur et son protagoniste doivent porter le même nom). Vilain assouplit néanmoins cette définition en admettant que le narrateur-personnage puisse rester anonyme : c’est l’autofiction « anominale ». L’article examine la pertinence théorique de cette thèse et sa mise en oeuvre dans les romans de Vilain.

TIPE (TNFAIP8) has been identified as an oncogene and participates in tumor biology. However, how its role in the metabolism of tumor cells during melanoma development remains unclear. Here, we demonstrated that TIPE promoted glycolysis by interacting with pyruvate kinase M2 (PKM2) in melanoma. We found that TIPE induced PKM2 dimerization, thereby facilitating its translocation from the cytoplasm to the nucleus. TIPE-mediated PKM2 dimerization consequently promoted HIF-1α activation and glycolysis, which contributed to melanoma progression and increased its stemness features. Notably, TIPE specifically phosphorylated PKM2 at Ser 37 in an ERK-dependent manner. Consistently, the expression of TIPE was positively correlated with the levels of PKM2 Ser37 phosphorylation and cancer stem cell markers in melanoma tissues from clinical samples and tumor bearing mice. In summary, our findings indicate that the TIPE/PKM2/HIF-1α signaling pathway plays a pivotal role in promoting cancer stem cell properties by facilitating the glycolysis, which would provide a promising therapeutic target for melanoma intervention.

The present study was conducted at the Instructional Fish Farm, College of Fisheries, Acharya Narendra Deva University of Agriculture and Technology, Ayodhya, Uttar Pradesh, in earthen ponds (8m×8m×1m). The experiment for 90 days, using Labeo rohita advanced fingerlings (avg. wt. 30.0 ± 0.5g) under sodic soil conditions. Five treatments were taken in triplicate, with 50 fingerlings per pond. T1 served as the control with traditional feed only (MOC+RB in 1:1 ratio, 5% of total fish body weight). T2 and T3 were fertilized with cattle dung (20 and t ha−1 yr−1) respectively. T4 and T5 received poultry droppings (10 and 7.5 t ha−1 yr−1) respectively. Results showed negative allometric growth (b<3), indicating fish becoming slimmer with length increase. Final weight gain was highest in T4 (110.9±0.9 gm) and T2 (108.7±0.88 gm), and lowest in T1 (70.7±0.49 gm).
A Modified SIVR Mathematical Model of Covid-19 Post-vaccination Stability Analysis in Kenya
Authors: M Mocheche George
Published: September 2024

In this paper, the study focused on carrying out a stability analysis on a modified SIR model for the COVID-19 pandemic for the period after vaccination in Kenya. The purpose of the work was to show that whereas the rate and the extent of disease spread amongst the Kenyan people was not as wide spread as happened in other parts of the world, it was necessary for government and policy makers to roll out a robust civic education to convince the majority of the Kenyan population to embrace vaccination as a major containment measure in curbing the spread of COVID-19 and other infectious diseases since the study revealed that the infections drastically reduced to near zero after vaccination except for a few isolated cases that were and still continue to exhibit mild symptoms to none at all. This was attributed to the development of the vaccine which upon a massive campaign by the Kenyan government, led into a significant portion of the population being vaccinated. It is believed this vaccination drive enhanced herd immunity amongst the population. This development has had a significant effect in the control of more recent COVID-19 variants like JN-1 that have remained largely mild and undetected in the country.  Both local and global post vaccination stabilities were analyzed for the system using the Lyapunov function. The main objective of the study was therefore to carry out a post vaccination stability analysis by estimating key parameters such as the basic reproduction number, ( R0)  and herd immunity threshold (HIT) for infectious diseases by fitting data into the model to enable predictions of future dynamics of the disease. The study used the Next Generation matrix and the least square method besides the Python software to solve generated differential equations of the model for  and HIT parameters. Results obtained showed that, there was a significant reduction in infections due to enhanced herd immunity attributed largely to the roll out of vaccination.

We carried out a theoretical study that considers the morphological factors and forces acting on a normal and a sickled blood cell. Sickle cell disease is associated with vaso-occlusion which creates blood flow crises as a result of loss in shape memory of the normal red blood cell. Certain forces and chemical compositions acting on the cell could retain the shape memory. The problem of a second order partial differential equation modeled was solved to get the forces and chemical composition required to restore the sickled red blood cells back to its original shape. The results gotten showed that, increase in chemical reaction increased the RBC growth by creating a stretching force that causes the sickle cell to regain elasticity with improved oxygen.

Maize, Zea mays L (Family: Poaceae), is a main cereal crop cultivated across diverse agro-climatic regions worldwide. The Fall Armyworm (FAW), Spodopterafrugiperda (J. E. Smith) (Lepidoptera: Noctuidae), migratory insect is notorious for its economic impact, inflicting severe damage on various crops including maize, rice, sorghum, millet, sugarcane, vegetables, and cotton, and has been documented to affect over 80 other plant species. A roving survey was carried out in four major maize growing blocks of Perambalur district viz., Perambalur, Veppanthattai, Alathur and Veppur during Kharif and Rabi season of 2023-2024. The experiment consisted of sixty standard weeks from 3rd July 2023 to 4th August 2024. The results indicated a positive correlation between the number of fall armyworm larvae/plant with Tmax, relative humidity (Evening), and the negative correlation was observed between the number of fall armyworm larvae/plant with Tmin, relative humidity (Morning), Sunshine and rainfall. The data concluded that the maximum temperature significantly influenced the emergence of the fall armyworm and its infestation on maize. The incidence of FAW started in 46th mean standard week MSW (13 larvae/plant) Alathur, (17.25 larvae/plant) Perambalur, (17.25 larvae/plant) Veppanthattai, (18 larvae/plant) Veppur and the population increased gradually and reached the peak in the 47th mean standard week MSW (26 larvae/plant) Alathur, (32.75 larvae/plant) Perambalur, (33 larvae/plant) Veppanthattai, (42 larvae/plant). Correlation analysis revealed that larval population showed a significant positive correlation with the maximum temperature and relative humidity. At the same time, minimum temperature, sunshine, and rainfall exhibited a negative association with larval incidence of S. frugiperda. Propose adaptation strategies for maize farmers in Perambalur to manage fall armyworm infestations in the context of changing weather patterns. This could include adjustments in planting dates, pest monitoring techniques, or integrated pest management approaches.

Land use and land cover (LULC) are distinct yet interrelated concepts that describe the characteristics and utilization of land. Land cover refers to the physical surface, such as vegetation, water bodies, or man-made features, while land use denotes the purpose of land utilization. Changes in LULC significantly impact water resources, making it a critical component in water resource studies. This study aims to detect changes in LULC over a five-year period (2017–2021) in the Kal River basin, a sub-basin of the Savitri River in Maharashtra, India. Sentinel-2 satellite imagery with a 10 m resolution was used, and the supervised classification method, specifically Maximum Likelihood Classification (MLC), was applied to classify LULC into six categories: cropland, bare ground, built-up areas, trees, rangeland, and water bodies. The results show that in 2017, the areas under cropland, tree cover, bare ground, built-up areas, and water bodies were 35.20 km², 187.61 km², 0.133 km², 7.77 km², and 1.89 km² respectively. By 2021, cropland, tree cover and bare ground decreased by 3.82%, 4.85%, and 0.01% respectively while water bodies, rangeland, and built-up areas increased by 0.02%, 8.34%, and 0.32% respectively. The overall accuracy of LULC classification was 77% for 2017 and 91% for 2021 with validation using the Kappa coefficient indicating good to excellent accuracy. This study highlights the importance of monitoring LULC changes for understanding the impacts of human activities and climate on watershed development and water resource management. Such analysis provides valuable insights for decision-makers to plan for sustainable development, land conservation and environmental management, ensuring balanced growth while protecting natural resources in the Kal River basin.
