    Soil erosion by water is a major global environmental concern due to its devastating effect on agricultural sustainability and food security. The aim of the current study was to investigate the effectiveness of agri-mats on water erosion control using a laboratory rainfall simulator. Six agri-mat samples were subjected to a runoff and infiltration rate test for this study: three agri-mats were made with 100% dry sugarcane bagasse and the other three agri-mats were made with 10% dry algae +90% dry sugarcane bagasse. The 100% dry sugarcane bagasse agri-mat treatment had higher runoff rate of 16.8 millimeters per hour (mm.hr−1) compared to a mere 1.7 mm.hr−1 recorded under the BA agri-mat during the first 10 min. In addition, the 100% dry sugarcane bagasse agri-mats released magnesium at a rate of 105.7 mg.hr−1 (milligrams per hour) compared to 6.6 mg.hr−1 lost from the 10% dry algae +90% dry sugarcane bagasse agri-mat treatment. Results shows that when algae was used as an additional organic material during the fabrication process, agri-mat delayed runoff by absorbing more moisture than it loses. Algae has the capacity to increase water-holding capacity while improving nutrient status and electrical conductivity of the agri-mats, making them more beneficial not only as the runoff combating technology but as a soil conditioner.

  • The Relations between telephony money transactions and inflation determination
    Authors: Dr. Christine N Simiyu and Beatrice Misorimaligayo
    The purpose of the paper was to examine the relationship between telephony money transactions and inflation in Kenya in the period 2007 to 2017 firstly, due to the fears allayed that the advent of mobile money transactions could be increasing inflation, and secondly, to determine the existence of causality between telephony money transactions and inflation. The ARDL Bounds test of co-integration is employed and the findings reveal that there is insignificant relationship between telephony money transactions and Inflation in the long run and the null hypotheses are accepted, however, the error correction terms are negative and significant showing bidirectional causality between inflation and the telephony money transactions constructs implying that there is need for continuous implementation of interdependent policy actions for effective monetary and inflation targeting.

  • HybridGBN-SR: A Deep 3D/2D Genome Graph-Based Network for Hyperspectral Image Classification
    Authors: Haron C. Tinega ,Enqing Chen ,Long Ma ,Divinah O. Nyasaka and Richard M. Mariita.
    This study proposes a deep 3D/2D genome graph-based network (abbreviated as HybridGBN-SR) that is computationally efficient and not prone to overfitting even with extremely few training sample data. At the feature extraction level, the HybridGBN-SR utilizes the three-dimensional (3D) and two-dimensional (2D) Genoblocks trained using very few samples while improving HSI classification accuracy. From the experimental results, the study shows that our model achieves better classification accuracy than the compared state-of-the-art methods over the three publicly available HSI benchmarking datasets such as the Indian Pines (IP), the University of Pavia (UP), and the Salinas Scene (SA). For instance, using only 5% labeled data for training in IP, and 1% in UP and SA, the overall classification accuracy of the proposed HybridGBN-SR is 97.42%, 97.85%, and 99.34%, respectively, which is better than the compared state-of-the-art methods.

  • Macroeconomic Factors and Asset Pricing from the Financial Institutions Concept in Kenya
    Authors: Dr. Fred Sporta & Dr. Ibrahim Tirimba
    This study aimed to unleash the role of macroeconomic factors on asset pricing among financial institutions. The study acknowledges that whilst portfolio diversification’s conceptualization is critical to the achievement of investment goals and risk management, a diversified portfolio across asset classes has no guaranteed diversified risk exposures.  From the empirical review it was established that big movements in stock prices of financial institutions do not line up with movements in long-term interest rates over the same period. The study also acknowledges that macroeconomic factors affect asset prices and that asset prices have significant influence on foreign exchange rates exposure on financial institutions.

  • Predicting Employability of Congolese Information Technology Graduates Using Contextual Factors: Towards Sustainable Employability
    Authors: Dr. Simon Nyaga. Mwendia
    Predicting employability in an unstable developing country requires the use of contextual factors as predictors and a suitable machine learning model capable of generalization. This study has discovered that parental financial stability, sociopolitical, relationship, academic, and strategic factors are the factors that can contextually predict the employability of information technology (IT) graduates in the democratic republic of Congo (DRC). A deep stacking predictive model was constructed using five different multilayer perceptron (MLP) sub models. The deep stacking model measured good performance (80% accuracy, 0.81 precision, 0.80 recall, 0.77 f1-score). All the individual models could not reach these performances with all the evaluation metrics used. Therefore, deep stacking was revealed to be the most suitable method for building a generalizable model to predict employability of IT graduates in the DRC. The authors estimate that the discovery of these contextual factors that predict IT graduates’ employability will help the DRC and other similar governments to develop strategies that mitigate unemployment, an important milestone to achievement of target 8.6 of the sustainable development goals.

  • Transactional and Transformational Leadership Styles, Sensing, Seizing, and Configuration Dynamic Capabilities in Kenyan Firms
    Authors: Dr. Lucy Simanii WamalwaLeaders play a vital role in the development of dynamic capabilities. However, the effects of leadership styles on firms’ dynamic capabilities have not been fully explored, with relatively few studies examining the relationship between leadership and dynamic capabilities. This research examined the influence of transformational and transactional leadership styles on dynamic capabilities. Using data from 279 Kenyan firms. Data analysis was done using a hierarchical linear regression model. The finding shows that transformational and transactional leadership styles influence the development of organizational dynamic capabilities. While the transformational leadership style leads to the development of sensing, seizing, and configuration capabilities, transactional leaders do not affect the development of sensing dynamic capabilities. However, they have significant effects on seizing and configuration capabilities development. This study develops knowledge that enables leaders, scholars and practitioners to understand how to use different leadership styles to pursue or develop different dynamic capabilities.

    Authors: Anthony C. Mwangi & Dr. Wycliffe M. Nyaribo

    Corporate governance structures are the systems and regulations created within an organization, to help guide the decision-making processes. This help in determining the respective roles to be played by various stakeholders in the organization. Corporate governance has been shown to have an impact on the performance of state corporations. However, most of these studies concentrate on the board structures and how they affect the financial performance of the organization in respect to Return on Equity, Return on Assets and Tobin’s Q. This research 4.2 Corporations in the education sector in Kenya. This area is least studied especially being a service-oriented and largely non-commercial sector. The objectives of the study are to establish the influence of CEOs attributes on performance, examine the influence of board structure on performance and find out the impact of the audit committee on performance of state corporations in Kenya. The study targets 171 respondents across 27 sampled state corporations under the education sector in Kenya. The respondents are drawn from senior and middle level managers, finance and account officers and internal audit staff. The 27 state corporations were selected using a stratified random sampling technique from the target population of 45 state corporations. The data was collected for the three objectives with specific questions on Board diversity, attributes of the CEO, Independence of the Audit Committee. The data collection tool used a close-ended questionnaire, there were 134 questionnaires returned out of the targeted 162, through a drop and pick method. The data collected was cleaned, coded and posted to SPSS Ver 23 for analysis. A regression model was applied to analyze the existing relationship between the variables; independent variables: CEO Attributes, Board Diversity and Audit Committee effect on the organizational performance being the dependent variable. Diagnostic tests were conducted to check for normality and multicollinearity. The study found that CEOs attributes, Board of directors’ diversity and audit committee had significant effect at α = 0.05 and contribute 27.7% of variations of performance in state corporations in education sector in Kenya. The study therefore recommends that, for enhanced performance of state corporations in the education sector in Kenya, stakeholders should appoint CEOs with rich experience, boards with diversity including gender and audit committee members who have higher qualifications especially, professional qualifications.

The study main source of data was primary data which was gathered using research questionnaires. The gathered data was assessed with the help of Statistical Package for Social Sciences (SPSS) Version 28. The study carried out both descriptive and inferential analysis to draw conclusions.

    Results: The inferential analysis results revealed that procurement contract management had a significant and positive influence on the sustainable performance of state corporations in Kenya at p<0.05. This indicates that contract preparation, contract administration, contract control and monitoring and contract conflicts resolution mechanisms are crucial drivers of sustainable performance of an organization. The model summary found that a unit change in procurement contract management may account for a variability of 45.1% in a firm’s sustainable performance. The R value for the model was 0.670 and the R2 was 0.451. This was a sign that the model was appropriate for establishing the link between procurement contract management and sustainable performance and, as a result, for drawing the conclusions and suggestions from the study.

  • Bayesian Model Averaging in Modeling of State-Specific Failure Rates in HIV/AIDs Progression

    Authors: Nahasho Mwirigi, Prof. Richard Simwa, Dr. Mary Wainaina & Dr. Stanley Sewe

    In modeling HIV/AIDS progression, we carried out a comprehensive investigation into the risk factors for state-specific-failure rates to identify the influential co-variates using Bayesian Model averaging method (BMA). BMA provides a posterior probability via Markov Chain Monte Carlo (MCMC) for each variable that belongs to the model. It accounts for model uncertainty by averaging all plausible models using their posterior probabilities as the weights for model-averaged predictions and estimates of the required parameters. Patients’ age, and gender, among other co-variates, have been found to influence the state-specific-failure rates highly. However, the impact of each of the factors on the state specific-failure was not quantified. This paper seeks to evaluate and quantify the contribution of the patient’s age and gender, CD4 cell count during any two consecutive visits, and state movement on the state-specific-failure rates for patients transiting either to the same, better or worse state. We used R Studio statistical Programming software to implement the method by applying BMS and BMA packages. State movement had a comparatively large coefficient with a posterior inclusion probability (PIP) of 0.8788 (87.88%). Hence, the most critical variable followed by observation-two-CD4-cell-count with a PIP of 0.1416 (14.16%), age and gender were the last with a PIP of 0.0556 (5.56%) and 0.0510 (5.10%) respectively for patients transiting to the same state. For patients transiting to a better state, the patients’ age group dominated with a PIP of 0.9969 (99.69%), followed by patients’ gender with a PIP of 0.0608 (6.08%). Patients’ CD4 cell count during the second observation had the least PIP of 0.0399 (3.99%). For patients transiting to a worse disease state, patients CD4 cell count during the second observation proved to be the most important, with a PIP of 0.6179(61.79%) followed by state movement with a PIP of 0.2599 (25.99%), patients gender tailed with a PIP of 0.0467 (4.67%).

  •  Weibull Distribution as the Choice Model for State-Specific Failure Rates in HIV/AIDS Progression

    Authors: Nahasho Mwirigi, Dr. Stanley Sewe, Dr. Mary Wainaina & Prof. Richard Simwa

    This study considered the problem of selecting the best single model for modeling state-specific failure rates in HIV/AIDS progression for patients on antiretroviral therapy with age and gender as risk factors using exponential, two-parameter, and three-parameter Weibull distributions. CD4 count changes in any two consecutive visits, the mean waiting time (μ), and transitional rates (λ) for remaining in the same state or transiting to a better or a worse state were analyzed. Various model selection criteria, namely, Akaike Information Criteria (AIC), Bayesian Information Criteria (BIC), and Log-Likelihood (LL), were used in each specific disease state. The Maximum Likelihood Estimation (MLE) method was applied to obtain the parameters of the distributions used. Plots of State-specific transition rates (λ) depicted constant, increasing, decreasing, and unimodal trends. Three-parameter Weibull distribution was the best for male patients and patients aged (40-69) years transiting in the states 1-2, 3-4, and 4-5, and 1-2, 3-4, and 5-6, respectively, and for male, female patients, and patients aged (40-69), remaining in the same state. Two-parameter Weibull distribution was the best for female patients and patients aged (20-39) years transiting in the states 1-2, 2-3, 4-5, and 1-2, 2-3, 3-4, respectively. Exponential distribution proved inferior to the other two distributions used.

  • Changamoto Zinazokumba Vijana Katika Tamthilia ya Kitumbua Kimeingia Mchanga

    Authors: Dr. Jackson N. Mwangi

    Katika ulimwengu wa sasa, kuna mabadiliko chungu nzima yanayoshuhudiwa duniani yanasababishwa na masuala anuwai kama vile maendeleo ya kiteknolojia pamoja na utandarithi yanayoathiri pakubwa maisha ya vijana. Nchini Kenya, vijana wana umuhimu wa kipekee kwani wanatekeleza majukumu muhimu sana katika kukuza uchumi wa nchi. Isitoshe, idadi ya vijana kote ulimwenguni imeendelea kuongezeka kila uchao na imepiku ile ya wazee.  Kwa hivyo, ni nyema kujadili changamoto zinazowakabili na kupendekeza hatua za kukabiliana nazo. Lengo la utafiti huu lilikuwa ni kuchanganua changamoto zinazowakumba vijana pamoja na athari zake katika ya tamthilia ya Kitumbua Kimeingia Mchanga ya S.A Mohamed (2000). Mada hii ilichaguliwa kwa misingi kwamba vijana wanakumbwa na changamoto nyingi katika maisha yao zinazowaathiri kwa kiasi cha haja na kutinga juhudi za kuafikia jaala zao. Utafiti huu ulilenga kubainisha changamoto zinazowakumba vijana katika tamthilia hii na kutambua mbinu ambazo vijana hawa wanazua ili kukabiliana nazo. Nadharia ya Uhalisia ilitumika kwa sababu ilionekana kufaa  zaidi  kuchanganua  changamoto  zinazowakumba  vijana. Hii ni kwa sababu  changamoto  hizi  zina uhalisia mkubwa katika maisha yao. Madhumuni ya utafiti huu yalikuwa ni kuchunguza na kueleza namna changamoto za vijana zinavyojitokeza katika tamthilia ya Kitumbua Kimeingia Mchanga na kisha kubainisha hatua zinazochukuliwa kuzitatua changamoto hizo. Utafiti huu ni wa kimaelezo na kiudhamano kwani ulihusisha kuchanganua matini zinazohusiana na mada husika.

  • Factors Affecting Financial Performance of Pension Schemes in Kenya.

    Authors: James Oyoo & Mackred Ochieng’

    The major function of pension funds is to provide ways for individuals to build up financial savings during their effective or working life in preparation for the funding of the consumption requires when they retire from active employment. Pension funds are the major sources of retirement income for many individuals worldwide. Despite the pension sub-sector growing, the faster growth in pension liabilities relative to assets as well as increasing life expectancy has elevated funding risks. In the defined contribution schemes, unremitted contributions have increased due to poor economic performance and the insufficient funding of quasi government schemes. This study sought to analyze the factors affecting financial performance of pension schemes in Kenya. The study specific objectives were to determine the influence of risk management, membership age, member contribution and firm size to determine their effect on the financial performance of the pension schemes. The study used 34 individual retirement benefits schemes registered with the Retirement Benefit Authority. The study used data for the period 2012-2021. The results revealed that there was a positive and significant relationship between risk management and financial performance of pension schemes. There was a negative and insignificant relationship between age of scheme members and financial performance of pension schemes. Member contribution had a positive and significant relationship with financial performance of pension schemes. Firm size revealed a positive and significant relationship with financial performance of pension schemes in Kenya. The null hypothesis on risk management, member contribution and firm size were rejected while that of age of the scheme members was not rejected. The study concluded that there is a strong correlation between risk management, age of scheme members, member contributions and firm size on financial performance of pension funds. The study recommended that pension funds should use the increasing value of their funds to generate returns for the pensioners. In addition, there is need to utilize assets to generate income for the pension funds and include the needs of the different age brackets in the management of the pension schemes.
