The study further revealed that there was significant relationship between sports facilities, staff club and employees’ quality service delivery and innovativeness in selected Rivers state owned tertiary institutions. It was recommended among others that; tertiary institutions in the state should have a mandatory once-a-month recreational day were all employees of the institution are mandated to engage in any recreational activity of their choice for the purpose of boosting their mental health and general job performance.

The Effects of Stress and Glossophobia on University Students' Attitudes toward Learning

Stress, a complex mental or emotional pressure resulting from external pressures, and glossophobia (the fear of public speaking) are two factors that play a role in the students’ academic life. The present research focuses on the impact of stress & glossophobia on the learning attitude of university students in Lahore-based universities. Stressing quantitative research methodology, the study seeks to demonstrate the effects of the two factors, stress and glossophobia, on student’s motivation, interactions, and approach to learning. In the course of the study, 200 students were selected with Student Stress and Glossophobia Questionnaire that measures levels of academic stress, public speaking anxiety, and the relationship between both parameters and learning behaviors. The research shows a high positive relationship between stress and glossophobia and a negative attitude towards learning. Stress was correlated with negative effects on the motivation and concentration of students, while glossophobia had an effect on the students’ willingness to engage in class discussions and presentations. The findings have indicated that psychological variables have a significant influence on the students’ academic environment and performance. The study therefore provides suggestions for stress relief management and coping strategies for glossophobia that universities should proceed to incorporate because modifications in student attitude and approach towards learning can clearly enhance performance.

Interaction between Leadership, Interpersonal Relationships and Organisational Climate: Case Study in the Peruvian Aymara region

In the dynamic outlook of current educational management, pedagogical leadership, interpersonal relationships and organisational climate emerge as fundamental pillars for institutional success. This research explores the intricate interconnection between these three crucial elements in the context of public elementary schools in the Aymara region of Perú. The methodology used corresponds to the quantitative approach and a descriptive-correlational design. The study analysed the perceptions of 125 teachers from six primary educational institutions by applying validated questionnaires. The findings reveal significant correlations between the variables; a high positive relationship between pedagogical leadership and interpersonal relationships (r=0.99), between pedagogical leadership and organisational climate (r=0.99), and between interpersonal relationships and organisational climate (r=0.96). It is concluded that there is a high degree of positive relationships between the three variables. These results validate the hypotheses put forward and underscore the critical importance of leadership in creating a harmonious and productive educational environment. The implications of this study are profound, highlighting how effective leadership can catalyse positive interpersonal relationships and, consequently, foster a healthy organisational climate, resulting in a cordial atmosphere for the educational community. Based on social and emotional skills, this synergy emerges as the key to achieving institutional goals in today's challenging educational environment. The analysis provided offers a solid foundation for future research and implementing more effective and holistic educational management strategies.

Impact of Open Government on Municipal Management Effectiveness: A study in the San Martin Region, Peru

The main objective of the research was to determine the relationship between open government and the effectiveness of municipal management in the region of San Martín (Peru). It is basic research because it sought to expand knowledge of the two variables, with a quantitative approach because it sought to demonstrate whether there is a relationship, a non-experimental design because the variables were not manipulated, descriptive correlational and cross-sectional because the instruments were applied at a single point in time. The population consisted of 926,000 citizens between 23 and 65 years of age who have had the experience of using the services of provincial municipalities and who, therefore, can offer a better criterion for evaluating open government and the effectiveness of municipal management. The sample consisted of 1537 people. The technique used was the survey, and two questionnaires were used as instruments, one for each variable, which made it possible to collect information from the ten provincial municipalities in the region. The results obtained were that the degree of open government was fair with 67% and the degree of effectiveness of municipal management was fair with 68%. It was concluded that there is a high and significant positive relationship between open government and municipal management effectiveness, as Spearman's Rho was 0.824 (high positive correlation) and a p-value equal to 0.000 (p-value ≤ 0.01). Furthermore, 74% of the variability between open government and municipal management effectiveness is due to other factors.

This study investigated the relationship between types of parental attachment, levels of self-esteem and academic performance among students in Mixed-day secondary schools in Masinga Sub- County, Machakos County, Kenya. The objectives included assessing types of parental attachment, examining self-esteem levels, assessing levels of academic performance, and establishing the relationship between these variables. Materials and Methods: The study was informed by Maslow’s theory of need and Bowlby’s attachment theory and adopted correlational research design. The target population comprised 4,796 students, with a sample size of 356 participants selected through simple random sampling. Parental Attachment Questionnaire, the Rosenberg Self-esteem Scale, and Demographic Questionnaires were used to collect data. Statistical Packages for the Social Sciences (SPSS version 25) software, descriptive statistics (frequencies and percentages) and inferential statistics (Pearson’s product-moment correlation analysis) were used to analyze data. Results: The study found that most (53.3%, n = 213) of the participants scored anxious parental attachment, 25.4% (n = 121) were at avoidance parental attachment, and 21.3% (n = 105) had secure parental attachment. It was also found that 70.5% (n = 281) of the participants scored low self-esteem, 6.7% (n = 27) were at high self-esteem and 43.6% (n = 174) were average in academic performance, 42.9% (n = 171) had low academic performance, while 13.5% (n = 54) had a high academic performance. Conclusion: The study established a negative but significant relationship (r = -.852, p =.000) between avoidance parental attachment and self-esteem. There was a moderate significant relationship (r = -.313, p =.000 ≤ 0.05) between anxious parental attachment and self-esteem. There was a high positive significant relationship (r = .766, p =.000 ≤ 0.05) between secure parental attachment and self-esteem. There was a strong positive significant relationship (r = .630, p = .003, ≤ 0.05) between secure attachment style and perceived academic performance. The study recommended that parents should listen to their children and be fully present in their lives. The parents should be made aware of the crucial stage of development of their adolescents and fully collaborate with teachers in school activities whenever they are called upon

The Predictive Roles of Organizational Culture and Psychological Symptoms on Job Satisfaction

This study was designed in a relational survey model to examine the relationships between teachers' organizational culture, job satisfaction and psychological symptoms. The predictive roles of teachers' perceptions of organizational culture and various psychological symptoms on their perceptions of job satisfaction were essentially. Data were collected by reaching 335 teachers working in public or private schools at primary, secondary and high school levels. According to the findings of the study, a high level positive relationship was observed between organizational culture and job satisfaction. A moderate negative relationship was found between teachers' negative self-perceptions and hostility feelings and job satisfaction. When negative self-perception and hostility variables are combined with school culture, they negatively affect teachers' perception of job satisfaction. This study shows that increasing job satisfaction, which is a vital issue for teachers for different reasons, can be possible by improving school culture and that the school culture variable can reduce the negative effect of negative self-concept and hostility on job satisfaction.

Integration of Co-Curricular Activities on Students ‘academic Performance in Public Primary Schools in Rwanda, A Case of Bugesera District

The main purpose of this research was to assess the influence of the integration of co-curricular activities on students’ performance in public primary schools in Rwanda, case of Bugesera district, Rwanda. This research was supported with attribution theory and involvement Theory. The researcher used descriptive research design for data collections. The participants were students, teachers and Head teachers. The participants comprised students, teachers, and head teachers, totaling 780 respondents, including 30 head teachers, 150 teachers, and 600 students selected from 30 sampled schools across 15 sectors of Bugesera District, Rwanda. The participants were chosen by using different methods where researcher used random sampling and purposive sampling. The responses for sports show that a significant majority of participants believe that sports are well integrated into public primary schools, with 58.7% agreeing and 36.6% strongly agreeing, making it a widely embraced activity. A very small percentage of respondents were neutral or disagreed, suggesting that sports play a prominent role in school co-curricular activities. Music, particularly through choir and instrumental activities, also enjoys considerable integration in schools, with 34.6% agreeing and 52.8% strongly agreeing to its presence. Findings on objective two indicated that The statements focus on satisfaction with co-curricular activities, participation, assessment, impact on learning, fairness, and the role of feedback in academic improvement. Satisfaction with Co-Curricular Activities, A significant majority of students express satisfaction with the co-curricular activities offered at their schools, with 60.2% strongly agreeing and 34.3% agreeing. The data reflects a strong and significant positive correlation between the two variables, with a Pearson correlation coefficient of 0.919 and a p-value (Sig. 2-tailed) of 0.000. The Pearson correlation coefficient 0.919 suggests a very high positive relationship between students' participation in sports and their academic performance. The government should create policies that support the integration of co-curricular activities as part of the national education curriculum.. The government should provide sufficient funding and allocate resources specifically for the development of co-curricular programs in public primary schools. The government should ensure regular monitoring and evaluation of schools to assess the implementation of co-curricular activities and their impact on students' academic performance.

Exploring the effect of online learners’ academic self-concepts on student engagement

The present study intends to evaluate the degree to which online university students’ academic self-perceptions predict variations in student engagement. The relational screening method was employed in this research. Data were collected from a total of 653 university students, 113 male and 539 female. The Student Engagement Scale (SES) and the Matovu Academic Self-concept Scale (ASCS) were utilised. Stepwise regression data analyses were conducted. Based on the results that the study yielded, it was observed that ASC had a high level of impact on student engagement, the levels of which varied across different factors of engagement. Academic effort and academic confidence variables accounted for 44% of the variance in behavioural engagement and showed a high positive relationship, while accounting for 33% of cognitive engagement with a moderate level of positive relationship. However, only academic effort was found to have a relationship with affective engagement, which was at a moderate level, accounting for 17% of the variance. Academic effort is relation with all student engagement factors. However, while academic confidence is only relation with behavioural and cognitive engagement, it is not relation with affective engagement. As a result, positively influencing student engagement in online learning environments will lead to positive changes in students' academic self-concept.

Analysis of communities, with an historical reconstruction from a deep submarine seamount in an oligotrophic area (Valencia Seamount, Balearic Basin, Western Mediterranean)

Seamounts can have strong influence on the dynamics and production of waters surrounding them, sometimes creating a kind of oasis effect. To assess to what depths and under what conditions this effect may persist on seamounts, we analysed the fauna and recent history of the Valencia Seamount (VS), a deep, small seamount (summit depth: 1056 m) from an oligotrophic zone of the Mediterranean Sea. The (living) epibenthic fauna of the VS summit (up to 1300 m) was composed of filter feeders, surface deposit feeders and carnivores (63 species), structured in a trophic chain as indicated by the high positive relationship (r2 0.502) between the δN15and δC13 of the fauna analysed. This trophic linearisation (compared with Catalan and NW Mallorca slope sites at similar depths) may optimise the energy flux reaching the seamount, with rather high %TOC (0.93–1.19%) and C/N (5.0–5.5) in July. The Valencia Seamount can also act as a reservoir zone for fish (grenadiers: Nezumia aequalis, and Hymenocephalus italicus) and shrimps (Plesionika martia), which are distributed at shallower depths on adjacent slopes, where they are exploited. The specimens caught were mainly juveniles, suggesting that these species may rather form pseudopopulations. Tuna and cetaceans were regularly sighted on the surface of VS during a specific period of the year (June–July). Reconstructing the recent history of Valencia Seamount (MC2 sediment core taken at 1151 m in 2021) we evidenced a decline of zooplankton pteropods (primary consumers) since ca. the 1960s (MC2 dating after 210Pb, metals and microplastic analyses), linked to a decline of Si in sediments suggesting a decrease in primary production due to a decrease in rainfall and river runoff. An increase of vorticity (ω+ values), i.e. of cyclonic gyres, and currents after the 1970s over the summit probably increased resuspension of organic matter, which in turn may enhance zooplankton aggegations at VS summit. We hypothesise that this would explain the parallel increase in mesopelagic myctophids in MC2 (from otolith records). Sediments of the Valencia seamount recorded several historical changes. Reconstruction studies carried out in oceanic areas can therefore help to understand the history and improve the management of fragile systems such as seamounts.

Biomarker responses of Mediterranean mussels (Mytilus galloprovincialis, Lamarck 1819) regarding marine mucilage in the Sea of Marmara

It has been proposed that marine mucilage intensifies the biological effects of chemical pollutants and can increase their bioaccumulation in seafood. Indeed, in 2021, mucilage caused a major environmental disaster in the Sea of Marmara. Limited resources on the possible effects of marine mucilage on sustainable food security have increased the importance of this study. The aim of this study is to investigate the biochemical effects of mucilage in wild and cultured mussels, a bioindicator species collected from four different regions [Istanbul Strait (S1) and Canakkale Strait (S2), Bandirma (S3), Gelibolu (S4)] during the 2021 fishing season in the Sea of Marmara. The levels of reduced glutathione and lipid peroxidation, activities of antioxidant enzymes like glutathione reductase, glutathione-S-transferase, catalase, superoxide dismutase, activities of biomarker enzymes like alanine aminotransferase, aspartate aminotransferase, and lactate dehydrogenase activities were determined. Our findings demonstrated that mucilage had an impact on cellular oxidative state and compromised the lipid cell membranes in the mantle tissues of Mediterranean mussels (Mytilus galloprovincialis, Lamarck 1819). It was found that there is a high positive relationship between seawater temperatures and bioparameters in S2 and S3 regions, except for GSH level. This study puts forward that in the presence of marine mucilage the biological responses and the state of health of mussels are negatively affected. Parameters which exhibit this kind of response may be used as biomarkers of exposure to marine mucilage in wild and culture mussel populations. Environmental disasters such as marine mucilage naturally affect food security by putting the sustainability of these species at risk.

A Comparison of Additional Benefit Assessment Methods for Time-to-Event Endpoints Using Hazard Ratio Point Estimates or Confidence Interval Limits by Means of a Simulation Study.

For time-to-event endpoints, three additional benefit assessment methods have been developed aiming at an unbiased knowledge about the magnitude of clinical benefit of newly approved treatments. The American Society of Clinical Oncology (ASCO) defines a continuous score using the hazard ratio point estimate (HR-PE). The European Society for Medical Oncology (ESMO) and the German Institute for Quality and Efficiency in Health Care (IQWiG) developed methods with an ordinal outcome using lower and upper limits of the 95% HR confidence interval (HR-CI), respectively. We describe all three frameworks for additional benefit assessment aiming at a fair comparison across different stakeholders. Furthermore, we determine which ASCO score is consistent with which ESMO/IQWiG category. In a comprehensive simulation study with different failure time distributions and treatment effects, we compare all methods using Spearman's correlation and descriptive measures. For determination of ASCO values consistent with categories of ESMO/IQWiG, maximizing weighted Cohen's Kappa approach was used. Our research depicts a high positive relationship between ASCO/IQWiG and a low positive relationship between ASCO/ESMO. An ASCO score smaller than 17, 17 to 20, 20 to 24, and greater than 24 corresponds to ESMO categories. Using ASCO values of 21 and 38 as cutoffs represents IQWiG categories. We investigated the statistical aspects of the methods and hence implemented slightly reduced versions of all methods. IQWiG and ASCO are more conservative than ESMO, which often awards the maximal category independent of the true effect and is at risk of overcompensating with various failure time distributions. ASCO has similar characteristics as IQWiG. Delayed treatment effects and underpowered/overpowered studies influence all methods in some degree. Nevertheless, ESMO is the most liberal one. For the additional benefit assessment, the American Society of Clinical Oncology (ASCO) uses the hazard ratio point estimate (HR-PE) for their continuous score. In contrast, the European Society for Medical Oncology (ESMO) and the German Institute for Quality and Efficiency in Health Care (IQWiG) use the lower and upper 95% HR confidence interval (HR-CI) to specific thresholds, respectively. ESMO generously assigns maximal scores, while IQWiG is more conservative.This research provides the first comparison between IQWiG and ASCO and describes all three frameworks for additional benefit assessment aiming for a fair comparison across different stakeholders. Furthermore, thresholds for ASCO consistent with ESMO and IQWiG categories are determined, enabling a comparison of the methods in practice in a fair manner.IQWiG and ASCO are the more conservative methods, while ESMO awards high percentages of maximal categories, especially with various failure time distributions. ASCO has similar characteristics as IQWiG. Delayed treatment effects and under/-overpowered studies influence all methods. Nevertheless, ESMO is the most liberal one. An ASCO score smaller than 17, 17 to 20, 20 to 24, and greater than 24 correspond to the categories of ESMO. Using ASCO values of 21 and 38 as cutoffs represents categories of IQWiG.

THE INFLUENCE OF COMPETENCY-BASED CURRICULUM PROMOTED STUDENTS’ INNOVATIVENESS IN SELECTED GOVERNMENT-AIDED SECONDARY SCHOOLS OF WAKISO DISTRICT, UGANDA. A CROSS-SECTIONAL SURVEY.

Background The study aims to establish a competency-based curriculum on students’ innovativeness in selected government-aided secondary schools of Wakiso District, Uganda. Methodology The study applied descriptive research design with qualitative and quantitative research approaches. Data was collected randomly from 10 head teachers, 30 class teachers, and 120 students using a self-administered questionnaire and a key informant interview guide. Results According to the study results, competency-based curriculum implementation was highly promoted or highly promoted students’ innovativeness in selected government-aided secondary schools of Wakiso District, Uganda. Through a competency-based curriculum, students became more innovative and creative. When students were instructed on competency, they were more likely to develop new problem-solving abilities, understand challenges that are prominent in the real world, become more competent in the use of technological gadgets like computers, and develop the ability to come up with alternative ways of addressing their problems. Therefore, a competency-based curriculum highly promoted students’ innovativeness in selected government-aided secondary schools of Wakiso District, Uganda. Thus a lot of support should be given to such schools to have competent students who will help in the development of the country. There was a high positive linear relationship between competency-based curriculum and students’ innovativeness. Conclusion Similarly, it was confirmed that a competency-based curriculum highly promotes students’ innovativeness in selected government-aided secondary schools of Wakiso District, Uganda. Recommendation The school administration should work hard towards ensuring that they offer necessary support to teachers, not only that but the teachers should be involved so much in the innovativeness of the students to give them an upper hand in whichever invention they may have come up with in the CBC. In addition, there should be rewards for best-performing teachers and students as a form of motivation to enhance the CBC in secondary schools.

Assessment of spring broad wheat varieties and lines for drought resistance in the conditions of the southern foreststeppe of Western Siberia using drought resistance indices

The experimental part of the work was carried out based on the seed production department of the Omsk Agrarian Research Center in 2020-2022. Breeding lines of spring soft wheat were represented by three ripeness groups: mid-early – G 6/17, G 8/17, G 10/17; mid-season - G 7/17, G 15/17, G 16/17 and mid-late - G 11/17, G 14/17, G 17/17. The varieties Pamyati Azieva, Duet, and Element 22 were standard. A complex system of indices was used to evaluate the samples for drought resistance, based on comparison of yields under stressful and favorable conditions. The most common indices were calculated: average productivity (MP), endurance index (TOL), yield stability index (YSI), drought resistance index (DI), and stress intolerance index (STI). The total rank score for all indices was calculated. Based on estimating a set of drought resistance indices, five samples with the highest number of points were identified: G 6/17, G 7/17, G10/17, G 11/17, and G 15/17, which can be used in further selection. The calculation of correlation coefficients revealed a high positive relationship between average productivity and the stress tolerance index (0.99), as well as the yield stability index (0.73), between the endurance index and the drought resistance index (0.89). A close positive relationship was also established between the stability and stress tolerance indexes (0.76), indicating a relatively high reliability.

Integrative analysis of the bladder cancer from a cell cycle NCAM1 perspective at both single cell and bulk resolution.

Bladder cancer (BLCA) is a prevalent and deadly form of urinary cancer, and there is a need for effective therapies, particularly for muscle-invasive bladder cancer (MIBC). Cell cycle inhibitors show promise in restoring control of the cell cycle in BLCA cells, but their clinical prognosis evaluation is limited. Transcriptome and scRNA-seq data were collected from the Cancer Genome Atlas Program (TCGA)-BLCA and GSE190888 cohort, respectively. R software and the Seurat package were used for data analysis, including cell quality control, dimensionality reduction, and identification of differentially expressed genes. Genes related to the cell cycle were obtained from the genecards website, and a protein-protein interaction network analysis was performed using cytoscape software. Functional enrichment analysis, immune infiltration analysis, drug sensitivity analysis, and molecular docking were conducted using various tools and packages. BLCA cell lines were cultured and transfected for in vitro experimental assays, including RT-qPCR analysis, and CCK-8 cell viability assays. We identified 32 genes as independent risk or protective factors for BLCA prediction. Functional enrichment analysis revealed their involvement in cell cycle regulation, apoptosis, and various signaling pathways. Using these genes, we developed a nomogram for predicting BLCA survival, which displayed high prognosis stratification efficacy in BLCA patients. Four cell cycle associated key genes identified, including NCAM1, HBB, CKD6, and CTLA4. We also identified the main cell types in BLCA patients and investigated the functional differences between epithelial cells based on their expression levels of key genes. Furthermore, we observed a high positive correlative relationship between the infiltration of cancer-associated fibroblasts and the risk score value. Finally, we conducted in vitro experiments to demonstrate the suppressive role of NCAM1 in BLCA cell proliferation. These findings suggest that cell cycle associated genes could serve as potential biomarkers for predicting BLCA prognosis and may represent therapeutic targets for the development of more effective therapies. Hopefully, these findings provide valuable insights into the molecular mechanisms and potential therapeutic targets in BLCA from the perspective of cell cycle. Moreover, NCAM1 was a novel cell proliferation suppressor in the BLCA carcinogenesis.

Organizational Commitment and Employee Performance during the COVID-19 Pandemic: Evidence from a BPO Company

The pandemic necessitated remote workplace setup, and as employees’ homes doubled as their workplaces, it became difficult to distinguish between the two. With this reality came the challenge of enhancing employee performance and organizational commitment. This study investigated the correlation between organizational commitment and employee performance during the COVID-19 pandemic. This study involved 158 employees of a BPO (Business Process Outsourcing) company situated in Quezon City, Philippines. Non-parametric statistical testing such as Mann–Whitney U and Kruskal-Wallis tests were employed to examine the significant differences in the respondent's ratings when their demographic profiles were considered. Spearman’s rank correlation was used to measure the strength of the relationship between the constructs of organizational commitment and dimensions of employee performance. Results of the study revealed a high positive relationship between continuance commitment and employee performance. Furthermore, this study also explored organizational commitment along four demographic variables, resulting in the detection of significant differences in the perception of continuance commitment on account of gender, age, civil status, and length of service. A significant difference was also detected in affective commitment considering the length of service. Single, married, and widowed respondents also differed in their opinions on normative commitment. While research on organizational commitment exist, few studies have explored the role of demographic factors in shaping employee responses to pandemics. This study demonstrates value by examining the influence of demographic variables on organizational commitment and employee performance during the pandemic, adopting an intersectional perspective, and offering practical implications for organizational management, theoretical advancement, and future research directions.
