Published: November 2024

The workforce is now composed of multi-generational employees. In the coming years, Millennials and Gen Z will dominate the labor force. The purpose of this study is to investigate the job satisfaction and organizational commitment of Millennial and Gen Z hotel employees. Understanding this future hospitality workforce is pivotal as empirical studies since both generations are known to be the “job hopper” generation. There has been a paucity in the study with regards to Gen Z hotel employees as they are still starting to penetrate the workforce. It was also the objective of this study to see whether there is a difference between Millennial and Gen Z employees in terms of their job satisfaction and organizational commitment. This study solely focused on hotel employees in Bacolod City (n = 90). The results of the study suggests Millennial and Gen Z employees are highly satisfied, and highly committed with their workplace despite of what previous studies suggest. However, the study also infers that gender of Gen Z employees shows a significant difference when it comes to job satisfaction. It is also extrapolated that employee’s job satisfaction has a strong positive relationship with their organizational commitment. This supports previous studies implying that job satisfaction is a predictor of organizational commitment.

Published: November 2024

Teaching autonomy has become an important factor in the modern context of an educational institution. Teachers are becoming more and more interactive with students, especially in managing students' educational work. A teacher's teaching style depends greatly on the environment and the decisions they can make independently. Teachers can work without restriction or fear. This study took place at a private Dominican Catholic school in the Philippines. The teachers of this educational institution are called learning facilitators because the school believes in the supporting role of teachers in the teaching and learning process. Learning facilitators can teach in their preferred method if they have enough autonomy to do so. Independence in the classroom can create more opportunities for instructors to teach lessons more expressively. In this way, instructors can enthusiastically carry out educational activities that will make students more satisfied. Student satisfaction in today's society is clearly very important. Their learning strategies are dynamic and dependent on the environment.

The study assessed the performance measures of rural development strategies in Ifelodun LGA of Kwara State. The instruments used in this study are questionnaires, key informant interviews, and observation. The adopted sample size for the study is 384 persons. Simple random sampling was used to distribute questionnaires proportionally to the nine districts according to population size. Data analysis for this research was descriptive and inferential.  Multiple regression analysis was used to measure the performance of development strategies in the study area. The result from the socio-economic characteristics of respondents revealed that 66% of the respondents were male, while 34% were female. Most (51.3%) of the respondents are within the age bracket of 31-45 years. It was also observed that over 90% of the respondents have attained one level of formal education or the other and apart from 17.13% and 28.73% that engage in civil service and business enterprises other than farming, 44.20% of the respondents are solely farmers and 94.5% earn above ₦20,000 monthly. Furthermore, the State Government was the major contributor to health, transport, agriculture, and education with a percentage contribution of 28.2%, 30.4%, 29.6%, and 44.8% respectively. The regression analysis result revealed that 82% of the impact of development strategies implemented in the study area could be explained by the transport, health, and agricultural sectors. Therefore, the study recommends that the federal government be more involved in the development of the study area and rural dwellers should be involved in the initiation, planning, and execution of development programs.

Published: November 2024

Due to the incessant application of synthetic herbicides in the agricultural system coupled with a rapid increase in herbicide-resistant weed species across the globe, much attention has been focused on alternative weed management, including allelopathy, which is eco-friendly and reduces reliance on synthetic herbicides. The effect of Sida cordifolia root and leaf ethyl acetate extract was evaluated under field conditions to determine its effects on growth, physiological response, stomatal index and density, and biochemical activity on weed species (Panicum maximum, Panicum repens, and Andropogon gayanus), as well as its effects on soil micronutrients. S. cordifolia root and leaf were collected from the wild in Nigeria and prepared into powder, which was dissolved to obtain the following concentrations 10, 20, 40, 60, and 80%, and distilled water served as the control. The percentage inhibition seems to be correlated with different growth indices as proven by an increase in malondialdehyde (MDA) content, reactive oxygen species (ROS), glutathione transferase (GST), and peroxidase (POD). Physiological growth indices such as plant height, leaf area, number of leaves, dry weight, stomatal density, and stomatal index were inhibited in both weed species while biochemical parameters such as Chlorophyll a, b, total chlorophyll and chlorophyll stability index were slightly reduced, increase in MDA, GST, ROS and POD were also noticed. In general, Andropogon gayanus showed a high inhibition rate compared to tomato. It is therefore recommended that concentrations of the Sida cordifolia extracts be increased to have a robust effect on the physiological processes of the weed species.

Published: November 2024

The problem of domestic energy demand and consumption between two contrasting communities, Sangere Village and Modibbo Adama University of Technology Yola (MAUTECH) Campus, in Gerei Local Government has been examined. The study aims to investigate whether the rate and choice of energy utilization of the two different communities will impact sound environmental management. Thus, they highlighted some of the socio-demographic factors that informed the choice of domestic energy types and the volume used as well as some environmental repercussions between these contrasting communities. Data was gathered using a questionnaire survey of 120 adult residents and was complemented by personal observation. The result indicates fuelwood was the highest energy utilized (30%) in the Sangere community, while the highest energy choice in MAUTECH community was cooking gas (27%). The implication of this perpetual fuelwood utilization, especially among Sengere residents will exacerbate deforestation, soil erosion, and air pollution, thereby undermining sustainable environmental management. Thus, a serious awareness campaign is urgently needed among Sangere residents where the literacy rate is low and population growth is visible. The study finally recommends government policies/legislation and public enlightenment/education as a panacea to attitudinal change for sound environmental management in the area.

The number of Internally Displaced Persons (IDPs) camps has increased recently in Nigeria due to insurgency and natural disasters such as floods. This study aimed to evaluate the sub-chronic toxicological effects of the source of the drinking water in Wassa camp, Abuja, Nigeria. Forty-eight (48) mice were randomized into four (4) groups of twelve (12) mice each and orally administered different concentrations (5, 10, and 20 mL/kg body weight respectively) of the water sample from Wassa IDP for fourteen (14) days. The alteration was noticed in the liver and kidney indices of mice by a significant increase (p<0.05) in kidney-body weight ratio, kidney, liver and plasma protein concentrations, and a considerable decrease (p<0.05) in albumin, creatinine, uric acid and total bilirubin concentrations, 14-days post-treatment, particularly at a higher dose. Gamma-glutamyl transaminase in the liver and aspartate transaminase in both liver and kidney significantly (p<0.05) increased in mice with a resultant significant decrease (p<0.05) in the serum, 14 days post-treatment at 20 mL/kg bwt. There was no significant difference (p>0.05) observed in serum triglycerides, very-low-density-lipoprotein cholesterol concentrations at all doses 14-days post-treatment compared with the control but the concentrations of serum low-density-lipoprotein cholesterol and total cholesterol significantly reduced (p<0.05) at 20 mL/kg bwt 14-days post-treatment. The drinking water altered some liver-function indices while the cardiac-function indices were less affected. Therefore, prolonged consumption of the water may not be relatively safe. The provision of clean drinking water for the Wassa IDP camp will prevent adverse biochemical reaction reactions from prolonged water consumption.

Published: November 2024

Introduction During the COVID-19 pandemic, extensive research was conducted on SARS-CoV-2; however, important questions about other respiratory pathogens remain unanswered. A severe influenza season in 2022–2023 with simultaneous circulation of SARS-CoV2 and respiratory syncytial virus is anticipated. This sub-study aims to determine the incidence and impact of these respiratory viruses on healthcare workers, the symptoms they experienced, the effectiveness of both COVID-19 and influenza vaccination and the burden of these infections on the National Health Service (NHS) workforce. Methods and analysis This is a longitudinal prospective cohort sub-study, utilising the population and infrastructure of the SARS-CoV-2 Immunity & Reinfection Evaluation (SIREN) study, which focuses on hospital staff in the UK. Participants undergo fortnightly nucleic acid amplification testing on a multiplex assay including SARS-CoV-2, influenza A and B and RSV, regardless of symptoms. Questionnaires are completed every two weeks, capturing symptoms, sick days, exposures, and vaccination records. Serum samples are collected monthly or quarterly from participants associated with a SIREN site. This sub-study commenced on 28/11/22 to align with the predicted influenza season and participants’ influenza vaccine status. The SIREN Participant Involvement Panel shaped the aims and methods for the study, highlighting its acceptability. UK devolved administrations were supported to develop local protocols. Analysis plans include incidence of asymptomatic and symptomatic infection, comparisons of vaccination coverage, assessment of sick day burden, and effectiveness of seasonal influenza against infection and time off work. Data are also integrated into UKHSA nosocomial modelling.

Authors: Cranfill Jennifer
Published: November 2024

Rejecting rationality, space, and linear time, Julio Cortázar’s “Axolotl” is an ecocritical text that problematizes humancentric logic and refutes coloniality. Cortázar crafts uncertainty through ambiguity and constructs a shifting narrative for both the human (man) and non-human (axolotl) Latin American exiles in this posthumanistic short story that resolutely resists colonial ways of thinking and knowing.

The experimental liquid-liquid equilibrium (LLE) data for the extraction of methanol from aqueous solution using mixed solvents (toluene + cyclohexanol) at 291.15 K and atmospheric pressure at the ratios (0, 0.25, 0.4, 0.6, 0.8, 1) was studied. The values of the solvent ratio 0 and 1 led us to study the liquid-liquid equilibrium of the ternary systems (water/methanol/cyclohexanol) and (water/methanol/toluene). The compositions of the coexisting phases were determined by the cloud point method. The tie line data for ternary and quaternary systems were correlated by NRTL model. The Othmer-Tobias and Hand correlations were also tested, to verify the reliability of the experimental tie lines data. The separation factor and the distribution coefficient were calculated from the experimental data to evaluate the effect of using mixed solvents. It was found that the ratio M = 0.4 is the best suited for the liquid-liquid extraction of methanol from water.

Enhanced Electromagnetic Wave Absorption in Hexaferrite/LSMO Bilayers: Optimization of Structural Design Using a High Frequency Software Simulation
Authors: Heo Jae-Hee , Lee Tae-Woo , Kang Young-Min , Lee Sang-Min
Published: November 2024

In this study, the electromagnetic (EM) wave absorption properties of a two-layered structure composed of La0.7Sr0.3MnO3-epoxy (10 wt.%) (LSMO) and SrFe9.5Co1.25Ti1.25O19-epoxy (10 wt.%) (SFCTO), both exhibiting distinct high-frequency magnetic and dielectric properties, were investigated using a High Frequency Simulation Software (HFSS) simulation tool. LSMO had a high dielectric constant (ε' >30) within the measurement range (0.1-18 GHz), indicating that dielectric loss mechanisms primarily contribute to EM wave absorption. In contrast, SFCTO is a material capable of significantly absorbing EM waves near 10 GHz due to ferromagnetic resonance (FMR). The simulations were validated by comparing the measured and simulated reflection losses (RL) of an unpatterned LSMO/SFCTO bilayer. The RL spectra were examined by varying the layer thickness and pattern size in three configurations: a continuous LSMO/SFCTO structure, a cross-patterned LSMO on SFCTO, and a square-patterned LSMO on SFCTO. In the continuous LSMO/SFCTO structure, tunable absorption frequency bands were achieved by adjusting the layer thickness. However, it was difficult to achieve broadband absorption due to the reflective characteristics of the high dielectric LSMO layer. The cross-patterned LSMO structure on SFCTO demonstrated broader bandwidth absorption, with layer thickness being more influential than pattern width. The square-patterned LSMO on SFCTO exhibited the best broadband EM wave absorption (max Δf = 7.39 GHz). These results suggest that broader absorption is achievable by partially covering the high-dielectric layer with patterns on a hexaferrite sheet.
Discovery of Alloy Catalysts for Ammonia Decomposition by Machine Learning-Based Prediction of Adsorption Energies
Authors: Yeo Byung Chul , Jeong So Yun , Kim Jun Su , Kim Donghun
Published: November 2024

Ammonia decomposition has gained significant attention as an eco-friendly method for hydrogen production because it creates no carbon dioxide emissions. While Ru catalysts are known for their high activity in ammonia decomposition, their high cost makes them uneconomical for commercial use. Therefore, it is essential to explore novel alloy catalysts composed of inexpensive elements with high catalytic performance. Nitrogen adsorption energies serve as key descriptors indicating the catalytic performance for ammonia decomposition, and first-principle calculations can compute these energies. However, the screening of numerous alloy catalyst candidates through extensive first-principle calculations and experimental validations remains time-consuming due to the vast number of potential candidates. To address this, artificial intelligence and machine learning models are being developed to quickly predict catalyst performance, efficiently searching for promising catalyst candidates. In this study, we developed a machine-learning-based method to rapidly predict nitrogen adsorption energies using a graph-based artificial neural network, thereby efficiently searching for novel catalysts for ammonia decomposition. Our training dataset included the nitrogen adsorption energies of 30 pure transition metal catalyst candidates, as well as binary alloy catalyst candidates, including core-shell and intermetallic compounds. As a result, we successfully identified 12 catalyst candidates composed of inexpensive elements that are likely to exhibit catalytic performance comparable to Ru catalysts.
Elevated Interleukin-6 (IL-6) Levels with Ig (G & M) Antibodies in the Recovery Phase of Patients with COVID-19: Indication of Cytokine Storm and Re-infection
Authors: Bolodeoku John , Gbaa Terry
Published: November 2024

The innate immune response to coronavirus disease (COVID-19) by inflammatory cytokines, such as interleukin 6 (IL-6), has been described as an early response, followed by an adaptive immune response with the production of antibodies. IL-6 is produced in response to viral infections and is crucial for the activation of T cells and the differentiation of B cells, which produce antibodies. Immunoglobulin M (IgM) and immunoglobulin G (IgG) antibodies are produced during the initial acute period of infection and the recovery period from the period of onset of symptoms. There has been some relationship between the innate response of the cytokine and the adaptive response of the antibodies in patients with COVID-19 infection. There has been a positive correlation between IL-6 levels and the presence of COVID-19 antibodies, suggesting that higher IL-6 levels may be associated with a stronger immune response and studies have confirmed that patients with higher IL-6 levels have a higher antibody response. High IL-6 levels on admission observed within 2 weeks after onset of symptoms were positively correlated with high concentrations of IgG seen 5 weeks after onset of symptoms. We have previously described elevated IL-6 levels in the sera of 68% of COVID-19 convalescent patients (40–93 days) post-onset of symptoms (recovery phase). In this study we decided to investigate whether there was some relationship between the IL-6 levels in patients 40–93 days post-onset of symptom in the recovery phase and their antibody response using a wide range of antibody assays (iCHROMA IgG, GOLD IgG & IgM, Abbott SARS-CoV-2 IgG II Quant-test (Abbott S IgG), Diasorin Liaison SARS-CoV-2 S1/2 (Diasorin S1/2 IgG). The patients were divided into two groups, those with normal IL-6 levels (<7 pg/ml) and those with elevated IL-6 levels (>7 pg/ml). All patients (100%) had positive IgG antibodies, only 8 out the 28 patients (29%) were positive for IgM antibodies. The mean antibodies concentrations of the patients (n = 9) with normal IL-6 levels (<7 pg/ml) for iCHROMA IgG (20.0 Units), GOLD IgG (34.4 AU/mL), Abbott IgG (4175 AU/mL), Diasorin Liaison IgG (75.8 AU/mL) and GOLD IgM (4.7 AU/mL), respectively. The mean antibodies concentrations of the patients (n = 19) with elevated IL-6 levels (>7 pg/ml) for iCHROMA IgG (20.9 Units), GOLD IgG, (34.9 AU/mL), Abbott IgG (2287 AU/mL), Diasorin Liaison IgG (121.7 AU/mL) and GOLD IgM (11.2 AU/mL), respectively. The antibodies of the patients with the elevated IL-6 levels were significantly higher for Diasorin Liaison IgG (p = 0.02) and GOLD IgM (p = 0.003) but lower for Abbott IgG (p = 0.02). In conclusion, this study using a panel of antibody assays highlights that increased levels of IL-6 in the convalescent phase (recovery phase) indicate an active immune response leading to higher concentrations of antibodies especially IgM, suggesting that cytokine storms and re-infection occur in the recovery phase.
Combating PDAC Drug Resistance: The Role of Ref-1 Inhibitors in Accelerating Progress in Pancreatic Cancer Research
Authors: Kpenu Eyram K. , Kelley Mark R.
Published: November 2024

Pancreatic Ductal Adenocarcinoma (PDAC) remains one of the most lethal solid tumor diagnoses given its limited treatment options and dismal prognosis. Its complex tumor microenvironment (TME), heterogeneity, and high propensity for drug resistance are major obstacles in developing effective therapies.

Here, we highlight the critical role of Redox effector 1 (Ref-1) in PDAC progression and drug resistance, focusing on its redox regulation of key transcription factors (TFs) such as STAT3, HIF1α, and NF-κB, which are pivotal for tumor survival, proliferation, and immune evasion. We discuss the development of novel Ref-1 inhibitors, including second-generation compounds with enhanced potency and improved pharmacokinetic profiles, which have shown significant promise in preclinical models. These inhibitors disrupt Ref-1’s redox function, leading to decreased TF activity and increased chemosensitivity in PDAC cells. We further detail our utilization of advanced preclinical models, such as 3D spheroids, organoids, and Tumor-Microenvironment-on-Chip (T-MOC) systems, which better simulate the complex conditions of the PDAC TME and improve the predictive power of therapeutic responses.

By targeting Ref-1 and its associated pathways, in conjunction with improved models, more replicative of PDAC’s TME, we are focused on approaches which hold the potential to overcome current therapeutic limitations and advance the development of more effective treatments for PDAC. Our findings suggest that integrating Ref-1 inhibitors into combination therapies could disrupt multiple survival mechanisms within the tumor, offering new hope for improving outcomes in this challenging cancer.

At the beginning of 2024, from January to April, there was a downward trend in the rupiah exchange rate against the United States dollar. This downward trend also occurred in various countries in ASEAN. This trend is of course influenced by several factors, both internal and external. This research aims to analyze the internal and external factors that cause this tendency. The data in this research is secondary data and comes from the International Monetary Fund (IMF) at CEIC. This research uses descriptive analytical-qualitative methods. The results of this research show that interest rates, inflation, and net exports in the short term do not have a significant effect on exchange rate movements. However, this depreciation factor trend is more influenced by global geopolitical problems and the size of a country's economy. Geopolitical issues and the size of the economy affect a country's balance of payments (BOP) and foreign exchange reserves, which in turn influence exchange rate movements. Researchers hope that this research can provide new information for the academic community and become material for consideration, suggestions, and input for government authorities who have internal decision-making authority regarding exchange rates.

Published: November 2024

In order to determine the impact that the Return On Asset (ROA), Current Ratio (CR), and Debt to Asset Ratio (DAR) have on the stock prices of health sector companies that are listed on the Indonesia Stock Exchange (IDX) between the years 2020 and 2023, this study will investigate the correlation between these three ratios. Secondary data are utilized in the research process. The approach of purposive sampling was utilized in order to identify ten businesses that met the requirements. The method of analysis that is utilized is called panel data regression, and it is realized through the utilization of the EViews 12 application. It has been determined that the fixed effect model (FEM) is the most effective model for panel data regression. In contrast to ROA, which did not have a significant relationship with stock price effects, the results showed that CR and DAR were marginally related to stock price influences (t test). It is also important to note that the three factors ROA, CR, and DAR all have an impact on stock prices simultaneously. With a value of 69.7%, the independent variable exerts a strong influence on the variable that is being studied. Due to the fact that these three factors are representative of the stock price of the company, the research was carried out with the intention of supporting investors in the process of decision-making and companies in the process of developing financial policies.

Published: November 2024

In the current digital era, a new payment concept has emerged, namely Paylater. Paylater carries the concept of 'Buy now, pay later'. The Paylater feature is increasingly popular because it has entered the E-commerce (online shopping) market. The paylater feature is in demand by various groups, especially the millennial generation, because it makes it easier to shop online if you don't have money. However, the paylater feature also has a negative side that can build consumer behavior. This research analyzes and determines the sharia economic perspective on online shopping paylater features for the millennial generation. This research was conducted using qualitative and quantitative survey methods by analyzing respondents' answers to surveys distributed based on the respondents' experiences. The research results state that most of the millennial generation use the paylater feature to shop online. The millennial generation who tends to like shopping via E-commerce uses the paylater feature to make their lifestyle more consumptive and can develop a habit of borrowing. Paylater itself is said to be haram from a sharia economic perspective because it contains things that are prohibited in Islamic principles.

Published: November 2024

This study explores the factors influencing employee knowledge hiding in construction industry organizations. Utilizing quantitative methods, the research examines the impact of demographic factors, including gender, age, educational level, marital status, and duration of service, as well as psychological contract breaches on employee knowledge hiding. An independent samples t-test and multiple comparisons using the least significant difference (LSD) test were conducted to analyze the demographic factors. At the same time, a simple linear regression analysis was employed to assess the relationship between psychological contract breach and knowledge hiding. The results indicate that demographic factors significantly affect employee knowledge hiding, with females, older employees, those with lower educational levels, divorced or widowed individuals, and employees with longer service durations tending to hide knowledge more frequently. Furthermore, psychological contract breach is found to have a strong and positive relationship with employee knowledge hiding, suggesting that employees are more likely to engage in knowledge-hiding behaviors when they perceive a violation of their psychological contract. The findings have important managerial implications, emphasizing the need for tailored strategies to address knowledge hiding among different employee groups and maintaining a strong psychological contract with employees to foster a culture of knowledge sharing and innovation.

Published: November 2024

With the development of China's economy, the number of policy supports provided by SMEs to private enterprises has also increased yearly. Their status and contribution to the national economy cannot be ignored. However, most private enterprises lack an understanding of small and medium-sized enterprises (SMEs) or do not comprehend the internal control mechanisms necessary to formulate and implement an effective internal control management system. This lack of understanding is the main bottleneck preventing enterprises from becoming larger and stronger. Enhancing internal management is particularly beneficial for improving the risk-prevention capabilities of small and medium-sized private enterprises, thereby facilitating their growth. This paper analyzes the problems faced by small and medium-sized private enterprises, using the internal supervision of the internal control system of Yinfeng Group as a case study. Based on internal control's basic and practical meanings, the paper provides suggestions to improve internal control management.

Published: November 2024

From the four variables, namely plagiarism, grammar, Artificial Intelligence (AI) consisting of ChatGPT and the journal publishing countries, namely Open University ASEAN and Indonesia, six hypotheses can be developed. The samples used were 40 research papers from two journals. However, the only one that has a correlation is a negative correlation between plagiarism and Artificial Intelligence (AI) detection. As plagiarism increases, Artificial Intelligence (AI) detection decreases. Conversely, when plagiarism decreases, Artificial Intelligence (AI) detection increases. This is a new problem that researchers in scientific writing must be faced.
