Authors: Kirui K , Kibue G
Published: July 2024

Purpose: This study investigated levels of awareness on climate change in five public universities in Kenya. The study aimed at assessing levels of knowledge on climate change issues among lecturers and students and documenting levels of access to information on climate change among lecturers and students.
Methodology: The study adopted a survey design. The population for the study consisted of 200 hundred undergraduates and lecturers. Data was analysed using both descriptive (frequency counts, percentages, means and standard deviations) and inferential statistics (Chi-square test) and presented in forms of charts and graphs.
Findings: The results showed that teaching staff and students possessed high level of awareness on the concept of climate change, have access to the sources of information and factors of personal experience, public sources and education greatly influence their awareness. There was a statistically significant association between years teaching at the University (Chi-Sq. = 72.844, DF = 3, P-Value = 0.000) and integration of climate change in the courses taught. However, we found no association between gender (Chi-Sq. = 2.534, DF = 1, P-Value = 0.111) and University (Chi-Sq. = 1.279, DF = 4, P-Value = 0.865) where a lecturer was teaching in terms of integration of climate change in the courses taught.
Unique Contributions to Theory, Practice and Policy: These ﬁndings indicate the teaching staff and students in Kenya have a widespread awareness of climate change and its immediate threat to human society, while knowledge of how to deal with the challenge due to climate change is still limited. Almost half the respondents believed climate change would result in impacts on human life. Nevertheless, the teaching staff and students need regular capacity development on climate change effects and in turn upscale the knowledge to the wider society.
RESESI SEKS : ANTARA KEBEBASAN INDIVIDU DAN HUKUM ISLAM
Authors: Asmita Sri , Fathimah Ema
Published: July 2024

Developed countries, a sexual recession has become a new trend among the community, manifested in the form of concerns about family responsibilities. The high regard for the legality of marriage by all religions is gradually shifting with the times. The institution of marriage is considered incompatible with the current lifestyle of society, especially in some non-Muslim majority developed countries. This article aims to examine and analyze how a sexual recession can occur, and what are the factors and implications of the sexual recession in the era of disruption. This research is qualitative and descriptive, collecting data through library research and observing phenomena by obtaining evidence through the internet and various social media platforms such as YouTube, Instagram, Google, and others. The article shows that sexual recession is prevalent in some developed countries such as Japan, the United States, South Korea, China, and so on. This is due to a decline in interest in sex, marriage, and having children. Sex and religion, especially Islamic law, seem to act as constraints on individual freedom, leading to a decline in population from all aspects of life This serves as evidence that the sexual recession in some countries, especially developed ones, is heavily influenced by religious dogma and free association. Therefore, a study is needed that confronts the epistemology of religious dogma, especially when confronted with Islamic law and individual freedom within marriage.
A Hermeneutical Evaluation of Luther’s Sola fide and its relevance to the Doctrine of Salvation in The Apostolic Church Nigeria, Southwest Zone
Authors: Nicolas Whesin, Olufemi
Published: July 2024

Purpose: The study evaluates Luther’s theory of sola fide and its relevance to the doctrine of salvation in The Apostolic Church Nigeria, Southwest Zone. The doctrine of sola fide typically entails the notion that salvation is through faith only. Unfortunately, in contemporary times, the concept of salvation has suffered much misunderstanding. It has been a subject of much controversy characterised with so much variations and confusion of thoughts in its art of teaching.
Materials and Methods: Employing the tool of hermeneutics and critical assessment, the study comparatively examined the theo-linguistic implications of Luther’s sola fide and TACN’s doctrine of salvation.
Findings: The study discovers that TACN’s doctrine of salvation shares fundamental similarities but TACN’s doctrine of salvation extends the doctrine of salvation further than Luther’s sola fide by emphasizing the possibility of a Christian losing his salvation. However, it is discovered and argued that TACN’s commitment to the doctrine of sola fide has not been balanced in practice. While the church professes that salvation is attained through faith only, her officials and members are observed to lay significant emphasis on salvation through works.
Implications to Theory, Practice and Policy: This study therefore recommends that the church should be consistent in its commitment to sola fide both in doctrine and practice. This can be achieved through consistency in the art of teaching what is believed by the church

Published: July 2024

This study determined the mediating effect of online learning self-efficacy on the relationship between social presence and engagement among college education students of three college schools in Davao del Norte, with 300 respondents. Specifically, this study aimed to determine the level of social presence, student engagement, and online learning self-efficacy; to determine the significant relationship between social presence and student engagement, social presence and online learning self-efficacy, online learning self-efficacy, and student engagement; to determine the mediating effect of online learning self-efficacy on the relationship between social presence and engagement. The researcher employed a stratified random sampling technique, utilizing Slovin’s formula to determine the optimal sample size. This study employed a non-experimental quantitative research design using a descriptive correlational approach. The results indicated a strong correlation between social presence, student engagement, and online learning self-efficacy, suggesting that these factors frequently contribute to high levels of achievement. The results demonstrated a partial mediation. The rejection of the hypothesis suggests a significant relationship among the three correlational variables. Thus, this proves that online learning self-efficacy plays an important role in the relationship between social presence and student engagement in online learning. Students with high self-efficacy in online learning are more likely to be engaged in their studies, even under challenging circumstances.

Authors: Algahtani Hussein , Shirah Bader , Jamaluddin Hussam A. , Abdelghaffar Nawal
Published: July 2024

Herpes simplex virus (HSV) encephalitis, predominantly caused by HSV-1, presents with significant morbidity and mortality challenges. This research investigates the particular role of adjunctive corticosteroid therapy in fulminant HSV encephalitis through in-depth analyses of two contrasting cases. Corticosteroids show potential benefits to improve an exaggerated immune response and limit viral dissemination within the brain. Daily assessments and frequent neuroimaging, particularly using magnetic resonance imaging, aid in the management of fulminant cases. Although existing evidence relies on limited case series and retrospective comparisons, the results of the present study emphasize the necessity for large-scale controlled trials to establish definitive guidelines. The discretion of the treating neurologist governs the decision to implement corticosteroids, emphasizing the imperative need for continued research and evidence-based strategies for this challenging neurological condition.

Published: July 2024

The relevance of this topic lies in the need to use economic and management strategies that can help agricultural enterprises adapt to a changing environment and ensure sustainable and resilient growth in the future. The purpose of the study was to examine the impact of economic and managerial factors on the development of agricultural enterprises, with a focus on creating sustainable business models. The methods used were analytical, statistical, and comparative. The paper examines the role of economics in the formation of sustainable business models of agricultural enterprises, focusing on optimizing the use of resources and adapting to market conditions. It is found that economic aspects include optimization of production processes, cost management and analysis of market trends. Efficient use of resources is a key aspect of sustainable business models of modern agricultural enterprises. The use of advanced technologies, such as precision farming and process mechanization, helps to increase productivity and reduce costs. Management of such market factors includes strategic planning, risk analysis and search for new development opportunities. An example of successful use of innovative technologies in agriculture is given on the sample of the American company John Deere. The article describes the strategy for developing sustainable business models for the Ukrainian company Myronivsky Hliboproduct, which includes the introduction of advanced agricultural technologies, diversification of production, optimization of resource use, development of local markets, improvement of risk management and promotion of social development of local communities. It is noted that the unfavourable conditions of war and economic instability pose serious challenges to the agricultural sector, but such conditions can also stimulate the search for new, more sustainable, and efficient business approaches. As a result, the development of sustainable business models for agricultural enterprises requires a comprehensive approach and systematic measures aimed at optimizing production, managing risks, and promoting the social development of local communities. The practical significance of the study lies in the possibility of increasing competitiveness, resource efficiency and sustainability in a changing market environment, which contributes to the sustainable development of the agricultural sector

Published: July 2024

The purpose of this study was to investigate the influence of climatic conditions of the research years on changes in productivity and environmental plasticity and stability of edible bean cultivars. Furthermore, the study investigated the nitrogen-fixing potential of edible bean cultivars for the biologisation of agriculture. The study was conducted in the conditions of the educational and production department of the Uman National University of Horticulture during 2020-2022, using nine cultivars of edible beans. Standard methods of statistical analysis were used to study the parameters of adaptive variability. As a result of the comparative study, the characteristics of various parameters of the adaptive potential of edible bean cultivars were established by the following traits: the onset of the technical ripeness phase: Bianco and Extra Grano Violetto – 78 days. The cultivars Windsor Broad (16.42 t/ha), Bianco (13.73 t/ha), and Svitiaz (11.51 t/ha) stood out in terms of yield and adaptability in the technical ripeness phase, the cultivars Bacchus (1.92 t/ha) and Svitiaz (1.90 t/ha) – in terms of yield and adaptability in the biological ripeness phase; cultivars with high protein content in immature grain: Karmazin (12.77 g/100 g), Windsor Broad (13.51 g/100 g), Bianco (14.30 g/100 g), and Green lowland (14.43 g/100 g); cultivars with high nitrogen-fixing capacity: Ukrainian Sloboda (67.7 kg/ha), Windsor Broad (71.0 kg/ha), and Extra Grano Violetto (75.7 kg/ha). The results of the statistical analysis showed a significant influence of environmental conditions on the formation of productivity indicators of edible bean cultivars and a greater dependence on environmental conditions (CVA = 10.40-82.7%) than on the genetic component (CVG = 5.76-39.7%). The data suggest a tendency for yields to be inversely related to yield stability, with low-yielding cultivars showing stability and high-yielding cultivars showing instability. The presented findings suggest an idea of the change in the productivity parameters of edible beans under contrasting weather conditions, which makes it possible to identify cultivars with high productivity for food purposes and with a higher proportion of high-protein and energy-rich consumer products. Cultivars with increased nitrogen-fixing capacity were identified, which will help reduce the use of synthetic fertilisers

Authors: Vales Cristine Joy A.
Published: July 2024

In the current digital era, education research is increasingly focusing on the correlation between computer literacy, science motivation, and academic achievement. Thus, this quantitative research aimed to determine the mediating role of science motivation on the relationship between computer literacy and the academic performance of Grade 6 learners during the academic year 2023-2024. Modified and adapted survey questionnaires from the Department of Education Computerization Program (DCP), Cagayan State University – Andrews Campus, and Glynn (2011), using a 5-point Likert scale, were employed for data collection. Analysis involved mean, two-way ANOVA, and path analysis. Results showed that the Grade 6 learners exhibited a high level of computer literacy in terms of computer integration (mean=3.78). The academic performance of Grade 6 learners indicated a very high level in terms of student-related factors (mean=4.3). Concurrently, Grade six learners are often more extrinsically motivated (mean=4.09). Significant indirect relationship was shown between computer literacy and academic performance through science motivation. Significant direct relationship was also shown between computer literacy and academic performance. The total effect estimates of 0.531 (SE = 0.0804, Z = 6.61, p < 0.001) suggests that there is a significant overall relationship between computer literacy and academic performance, regardless of the mediating effect of science motivation. Recommendations can be made for future researches as to longitudinal study, qualitiative researches, and intervention studies.

Authors: Mutua Elias , Ndeke Grace C W , Mboga Mary
Published: July 2024

This study aimed to find out the influence of public participation in the planning phase on the phase-specific outcome and overall outcome of water projects in the Matungulu sub-county, Machakos County, Kenya. Employing a sequential mixed-method approach, data was gathered from 220 household heads, one water project manager, and eight water user committee representatives. Quantitative data analysis was done using linear regression, and the hypothesis was tested at a significance level of 0.05. A thematic approach was employed for the qualitative data analysis. Results indicated that public participation in the planning phase significantly influenced both the planning phase-specific outcome and the overall water project outcome. However, the level of public participation in the planning phase was found to be low. The study recommends that the Machakos County government officials and elected representatives prioritise public consultation and involvement in the planning phase since it ensures that water projects implemented are relevant to the needs of the local residents and enhances project ownership at an early stage. This ultimately guarantees project success and sustainability. This study provides insights to both the national and county governments on how the involvement of the local community in the planning phase fosters project ownership and leads to more sustainable water projects.

Social interaction in the form of collaboration is one strategy that makes it easier to solve problems. Various learning strategies are chosen, with the hope that students can improve the quality of their knowledge and skills. This research aims to find best learning practices that can provide added value for anyone who reads it. This research is a qualitative descriptive study using the STAR method (Situation, Challenges, Action, Reflection on Results and Impact) to describe the implementation of lesson study. The results of this research show that the use of the problem based learning model makes students trained in their critical thinking skills. Students are more critical because they are trained to formulate their own problems. This is shown by the increase in student learning outcomes as evidenced by the results of formative tests carried out during learning with the highest score being 100 and the lowest score being 60. This learning success factor is largely determined by the teacher's competence in managing learning, especially in terms of selecting innovative learning models and media that are developed. in teaching modules so that students' critical thinking abilities can increase.

Aim: To prove that 2-year mortality of triple-negative breast cancer (TNBC) patients with protein Ki-67 expression ≥ 40% is higher than patients with protein Ki-67 expression < 40% in Prof. dr. I.G.N.G. Ngoerah General Hospital Denpasar. Methods: This was a bidirectional cohort study with survival analysis. The end of follow-up was the mortality state (survived or deceased) of patients observed for 24 months (2 years) since the patient was diagnosed with TNBC. This study was conducted in the Surgical Oncology Department, Prof. dr. I.G.N.G. Ngoerah General Hospital Denpasar from January 2018 until January 2022. The sample was recruited by a consecutive sampling method. The Kaplan-Meier curve and log-rank test determined overall survival (OS) and its difference between the Ki-67 expression group. Multivariate analysis using Cox regression was also conducted. Results: 58 TNBC patients were included in this study. At the end of the study, 31 patients survived, with an OS of 53.4%. The mean OS time was 19 months (95%CI = 17.12-20.88). The two-year OS of TNBC patients with Ki-67 ≥ 40% group was 37.5%; meanwhile, in Ki-67 expression < 40% was 88.9%. It was statistically significant (p = 0.001). Multivariate analysis revealed that Ki-67 ≥ 40% expression was a significant and independent predictor factor for a high 2-year mortality rate (adjusted HR = 9.140; p = 0.008). Tumor-resection history also had a significant result in multivariate analysis (p < 0.05). Conclusion: TNBC patients with Ki-67 ≥ 40% have a higher 2-year mortality rate than patients with Ki-67 expression < 40%.

MECHANISED COAL EXPLOITATION IN THE "BREZJE" PIT OF THE
"DJURDJEVIK" BROWN COAL MINE
Authors: Sarajlić Šefik , Musić Omer
Published: July 2024

In addition to the coal and electricity market and changing geopolitical circumstances, there are other sufficiently
rational reasons for opening new underground mining facilities and modernizing existing mining methods.Significant
limiting factors and influences, in complex mining-geological conditions, most significantly affect the possibilities of
the mechanized way of mining brown coal. The "Brezje" pit is a part of the deposit where the mining-geological
factors are complex and determined by the natural conditions of the deposit's genesis. Excavation methods and
technologies in complex deposit conditions must be based on great flexibility and adaptability.The complexity of the
tectonic structure in the "Đurđevik" pit justified the application of chamber excavation methods with borehole blasting,
in various technical modifications and solutions. In all previous solutions, the degree of mechanization of the method
was not significantly improved and all modifications of the chamber method were non-mechanized or semi-
mechanized with a large participation of manual work, technology based on drilling and blasting, high risk of injuries,
low utilization of deposits, unjustified economic effects of work.
The aim of this paper is to give an adequate answer to the hypothesis "in the block structure of the deposit with
pronounced tectonics, it is possible to reduce the unfavorable influence of the complex mining-geological factors of
the deposit on the excavation method by choosing modern mechanization for underground exploitation". The
mechanized chamber method of excavation is a conceptual solution for the possible application in complex conditions
of the proposed flexible mechanization for work in the "Brezje" pit. The advantage of modern multifunctional mining
machines is a high degree of adaptability to the elements of the coal layer with the use of different working mechanisms
(tools) that can be changed in a very short time depending on the working phase of the process.
Key words: Pit, complexity, factors, chamber method, flexible, multifunctional machine

Identifying decadal trends in deweathered concentrations of criteria air pollutants in Canadian urban atmospheres with machine learning approaches
Authors: Yao Xiaohong , Zhang Leiming
Published: July 2024

Abstract. This study investigates long-term trends of criteria air pollutants, including NO2, CO, SO2, O3 and PM2.5, and Ox (meaning NO2+O3) measured in 10 Canadian cities during the last 2 to 3 decades. We also investigated associated driving forces in terms of emission reductions, perturbations due to varying weather conditions and large-scale wildfires, as well as changes in O3 sources and sinks. Two machine learning methods, the random forest algorithm and boosted regression trees, were used to extract deweathered mixing ratios (or mass concentrations) of the pollutants. The Mann–Kendall trend test of the deweathered and original annual average concentrations of the pollutants showed that, on the timescale of 20 years or longer, perturbation due to varying weather conditions on the decadal trends of the pollutants are minimal (within ±2 %) in about 70 % of the studied cases, although it might be larger (but at most 16 %) in the remaining cases. NO2, CO and SO2 showed decreasing trends in the last 2 to 3 decades in all the cities except CO in Montréal. O3 showed increasing trends in all the cities except Halifax, mainly due to weakened titration reaction between O3 and NO. Ox, however, showed decreasing trends in all the cities except Victoria, because the increase in O3 is much less than the decrease in NO2. In three of the five eastern Canadian cities, emission reductions dominated the decreasing trends in PM2.5, but no significant trends in PM2.5 were observed in the other two cites. In the five western Canadian cities, increasing or no significant trends in PM2.5 were observed, likely due to unpredictable large-scale wildfires overwhelming or balancing the impacts of emission reductions on PM2.5. In addition, despite improving air quality during the last 2 decades in most cities, an air quality health index of above 10 (representing a very high risk condition) still occasionally occurred after 2010 in western Canadian cities because of the increased large-scale wildfires.

Abstract. Peatland restoration and rehabilitation action has become more widely acknowledged as a necessary response to mitigating climate change risks and improving global carbon storage. Peatland ecosystems require restoration time spans of the order of decades and, thus, cannot be dependent upon the shorter-term monitoring often carried out in research projects. Hydrological assessments using geospatial tools provide the basis for planning restoration works as well as analysing associated environmental influences. “Restoration” encompasses applications to pre-restoration and post-restoration scenarios for both bogs and fens, across a range of environmental impact fields. The aim of this scoping review is to identify, describe, and categorize current process-based modelling uses in peatlands in order to investigate the applicability and appropriateness of ecohydrological and/or hydrological models for northern peatland restoration. Two literature searches were conducted using the entire Web of Science database in September 2022 and August 2023. Of the final 211 papers included in the review, models and their applications were categorized according to this review's research interests in seven distinct categories aggregating the papers' research themes and model outputs. Restoration site context was added by identifying 229 unique study site locations from the full database, which were catalogued and analysed against raster data for the Köppen–Geiger climate classification scheme. A majority of northern peatland sites were in temperate oceanic zones or humid continental zones that experienced snow. Over one in five models from the full database of papers were unnamed and likely intended for single use. Key themes emerging from topics covered by papers in the database included the following: modelling restoration development from a bog growth perspective, the prioritization of modelling greenhouse gas (GHG) emissions dynamics as a part of policymaking, the importance of spatial connectivity within or alongside process-based models to represent heterogeneous systems, and the increased prevalence of remote sensing and machine learning techniques to predict restoration progress with little physical site intervention. Models are presented according to their application to peatlands or broader ecosystem and organized from most to least complex. This review provides valuable context for the application of ecohydrological models in determining strategies for peatland restoration and evaluating post-intervention development over time.

Abstract. The diversity effect on decomposition, through the litter-mixing effects plays a central role in determining the nutrient and carbon dynamics in ecosystems. However, the litter-mixing effects are centered on a leaf litter perspective. Important aspects related to intraspecific interaction and biomass concentration are rarely evaluated, even though they could be essential to determine the litter decomposition dynamics. To our knowledge, we introduced a new perspective to evaluate whether and how the interaction between flower and leaf litter affects the occurrence, direction, and magnitude of litter-mixing effects in terrestrial and aquatic ecosystems. We performed laboratory experiments using flower and leaf litter from the yellow trumpet tree Tabebuia aurea (Silva Manso) Benth. and Hook. f. ex. S. Moore as a model. To obtain realistic results, we manipulated various scenarios of flower : leaf litter biomass proportion and measured 13 functional traits. Litter-mixing effects were consistent in both aquatic and terrestrial environments, with faster decomposition of both litter types in mixtures compared to their monocultures (synergistic effects). Litter-mixing effects were stronger in the terrestrial environment and at higher flower : leaf litter biomass proportions. Our results indicate that synergistic outcomes are mainly associated with complementary effects. Flower litter had a higher concentration of labile C compounds, N, P, and K and lower lignin concentrations, representing a labile litter, while leaf litter had a higher concentration of lignin, Ca, Mg, and Na, representing a refractory litter. Our results demonstrate the importance of litter-mixing effects between flower and leaf litter via complementary effects. These results shed light on the secondary consequences of flower litter on decomposition, suggesting that species with high reproductive investment in flower biomass may play an important role in the nutrient and carbon recycling of diverse plant communities, exerting a pivotal role in biogeochemical dynamics.

Abstract. Sea ice governs the global climate, safeguards ecological equilibrium in polar regions, and influences ocean circulation; however, the factors impacting the spatial characteristics of sea ice deformation have not been comprehensively analyzed. This study examined the effects of wind speed, air temperature (T2m), and sea ice thickness on the variation in sea ice deformation within the western Arctic based on the Lagrangian diffusion theory using buoy data from March 2022 to March 2023. The total sea ice deformation gradually declined in all seasons except for the melting season, especially in the fall and winter. Owing to the ongoing sea ice consolidation, the average total deformation was lower in the fall and winter than in the spring. The total deformation of sea ice diminished as the spatial scale increased. As sea ice is thinner on average in spring, geostrophic winds are the primary factor influencing the spatial characteristics of sea ice deformation. In contrast, the larger average ice thickness in fall and winter reduces the significance of the external force, and T2m/sea ice thickness is the primary factor influencing the spatial characteristics of sea ice deformation. Our multivariate nonlinear regression model effectively predicted the total sea ice deformation. This study provides a scientific basis for climate change research, sea ice change prediction, climate model validation, resource management, and environmental protection.

Abstract. Climate sensitivity and aerosol forcing are two of the most central, but uncertain, quantities in climate science that are crucial for assessing historical climate as well as future climate predictions. Here, we use a Bayesian approach to estimate the inferred climate sensitivity and aerosol forcing using observations of temperature and global ocean heat content and prior knowledge of effective radiative forcing (ERF) over the industrial period. Due to limited information on uncertainties related to the time evolution of aerosol forcing, we perform a range of sensitivity analyses with idealized aerosol time evolution. The estimates are sensitive to the aerosol forcing pathway with the mean estimate of inferred climate sensitivity ranging from 2.0 to 2.4 K, present-day (2019 relative to 1750) aerosol ERF ranging from -0.7 to -1.1 W m-2 and anthropogenic ERF ranging from 2.6 to 3.1 W m-2. Using observations and forcing up to and including 2022, the inferred effective climate sensitivity is 2.2 K with a 1.6 to 3.0 K 90 % uncertainty range. Analysis with more freely evolving aerosol forcing between 1950 and 2014 shows a strong negative aerosol forcing trend in the latter part of the 20th century that is not consistent with observations. Although we test our estimation method with strongly idealized aerosol ERF pathways, our posteriori estimates of the climate sensitivities end up in the weaker end of the range assessed in the Sixth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC AR6). As our method only includes climate feedbacks that have occurred over the historical period, it does not include the pattern effect, i.e. where climate feedbacks are dependent on the pattern of warming which will likely change into the future. Adding the best estimate of the pattern effect from IPCC AR6, our climate sensitivity estimate is almost identical to the IPCC AR6 best estimate and very likely range.
