Luvembe AM, Mutai H. "Big Data Framework for Kenya’s County Governments." Journal of Computer and Communications. 2019;07(01):1-9. AbstractFull Text Link

Digitalization is transforming governments across the globe. At the national level, down to regional and multiple departments in the public institutions, unprecedented change is occurring exponentially as a result of massive digitalization. Digitalization is compelling governments at all levels to embrace voluminous data and institute appropriate multi-channel platforms to support digital transformation. While this is the case, most governments have been caught unprepared thwarting maximum benefits spurred by digitalization. Inherently, the social media and e-participation tools for generating huge amount of data have convoluted most governments’ appetite in Big Data management. This situation is further compounded with the slow pace of adoption of these technological tools by citizens and the public sectors. For enhanced e-citizen satisfaction and engagement, as well as e-participation processes, public institutions need to promote engagement and collaboration. In view of advancing benefits to their citizens, public institutions need to institute appropriate measures to collect citizen’s data. The information collected is vital for public institutions in actualizing what services the citizens want. Using literature reviews and cases, the authors examine Big Data benefits in counties and propose a Big Data model to improve efficiency of e-governance services and productivity in county governments. The authors demonstrate Big Data framework has the aptitude of molding citizen’s opinion in county decision making process. Better use of e-technologies is shown in the proposed model which illustrates sharing resources among various data analytics sources. Our proposed framework based on Big Data analytics is a viable initiative to progress effectiveness and productivity, strengthen citizen engagement and participation and encourage decision-making in e-governance services delivery in the counties.

Description
Swollen cellulose fibres isolated from water hyacinth were utilized in the synthesis of water hyacinth cellulose-graft-poly(ammonium acrylate-co-acrylic acid) polymer hydrogel (PHG). Acrylic acid (AA) partially neutralized with NH3 was heterogeneously grafted onto swollen cellulose by radical polymerization reaction using N,N-methylene-bis-acrylamide (MBA) as the cross-linker and ammonium persulphate (APS) as the initiator. The reaction conditions were optimized through assessment of grafting parameters such as grafting cross-linking percentage (GCP), percentage grafting cross-linking efficiency (%GCE) and water absorption tests. Characterization of the copolymer by Fourier Transform Infra-red (FTIR) spectroscopy revealed successful grafting of the monomer onto cellulose. Transmission electron microscopy (TEM) image of acetone-extracted PHG displayed micro-porous structure. The optimized product …

Abstract

Sorption of Congo Red (CR) and Malachite Green (MG) dyes currently used in pigments and clothing industries were investigated using brewers’ spent grain (BSG) from a local brewery. Adsorption increased with a higher adsorbent weight and lower colorant concentrations. Accumulation of CR and MG was optimal at acidic pH and neutral pH respectively. Sorption decreased with an increase in temperature signifying an exothermic process. Batch adsorption data fitted better to Langmuir adsorption isotherm model and pseudo-second-order kinetics. Maximum monolayer coverage capacities (
were found to be 2.55 mg/g for MG and 36.5 mg/g for CR dye. Column studies using BSG were also conducted for both dyes. Fixed bed breakthrough was fast with an increase in dye concentration, adsorbent surface area, and flow rate and with a decrease in column depth. BSG are effective, simple in design and inexpensive adsorbing material from renewable sources.

There is a gradual paradox shift from the utilization of surface water to groundwater in both urban and rural Kenya. This is because surface water is both diminishing in quantity due to climate variability and deteriorating in quality due to high levels of anthropogenic contamination. In the quest to attain the Sustainable Development Goal number 6 that aim at ensuring access to safe water by all by 2030, the Government of Kenya is encouraging the development of groundwater resources whose potential is enormous though it has not been quantified. The Inter-governmental Authority on Development (IGAD) supported this research on the shared Mt. Elgon trans-boundary aquifer between Kenya and Uganda aimed at understanding its dynamics. Mt. Elgon is a Tertiary age mountain that straddles the Kenya-Uganda border and has a trans-boundary aquifer. This study investigated the groundwater chemistry and its implication on water management and human health. Physico-chemical parameters of water that included electrical conductivity, pH, and temperature were measured in the field and the major cations and anions were measured at the Central Laboratories of the State Department for Water. Geological mapping and identification of sanitary risks were undertaken during the field work. The study revealed that the concentration of cations and anions in the groundwater varied spatially and temporally. Abundance of these ions were in the order Ca²⁺ > Na⁺ > Mg²⁺ > K⁺ for most samples and HCO₃⁻ > Cl⁻ > SO₄²⁻ >NO₃⁻. Interpretation of hydro-chemical data suggests that calcium carbonate dissolution, halite dissolution, Ca/Na ion exchange and Mg/Na ion exchange are the major processes that control the ground-water chemistry. Chemical results indicate further that the groundwater is suitable for domestic use but is threatened by both anthropogenic and geological factors. Extensive use of fertilizer and the destruction of the catchment area coupled with low permeability and rock-water interactions in the metamorphic rock terrains are the main threats to groundwater quality in the region. A few water points had water with some ionic composition exceeding WHO and the local KEBS maximum limits for drinking water. Such water pose a risk to human health.

Abstract

Tropical montane forests are amongst the most threatened ecosystems by climate change. However, little is known about climatic changes already observed in these montane areas in Africa, or the adaptation strategies used by pastoralist communities. This article, focused on three mountains in northern Kenya, aims to fill these knowledge gaps. Focus-group discussions with village elders were organized in 10 villages on each mountain (n = 30). Villages covered different pastoralist ethnic groups. Historical data on rainfall, temperature and fog were gathered from Marsabit Meteorological station. All participants reported changes in the amount and distribution of rainfall, fog, temperature and wind for the past 20–30 years; regardless of the mountain or ethnicity. They particularly highlighted the reduction in fog. Meteorological evidence on rainfall, temperature and fog agreed with local perceptions; particularly important was a 60% reduction in hours of fog per year since 1981. Starting farming and shifting to camel herding were the adaptive strategies most commonly mentioned. Some adaptive strategies were only mentioned in one mountain or by one ethnic group (e.g. starting the cultivation of khat). We highlight the potential use of local communities’ perceptions to complement climatic records in data-deficient areas, such as many tropical mountains, and emphasize the need for more research focused on the adaptation strategies used by pastoralists.

Based on a five-town case-study cohort in Kenya, a conceptual framework has been developed to enable the formulation of holistic and effective strategies that encompass the national aspirations and regional to global sustainability agendas, and which can be used to monitor progress in achieving set objectives. The approach is flexible, scalable and transferrable, so that it can be applied in different contexts and using different indicators, based upon the same construct. Insufficient technical knowledge of urban aquifers and their interplay with the wider social-ecological system constrains the development of holistic, effective and robust management systems to ensure their sustainability for intended uses. The objective was to consider governance and management solutions that could promote water security for urban towns in Kenya through the sustainable use of groundwater in the context of its complex hydrogeology, water access disparities, competing uses and future risks. The in force national and county water policies, strategies, and plans for the case study areas were critically reviewed. The status of aquifer knowledge, water access disparities, competing uses, and risks was evaluated from critical literature reviews and data compilation, fieldwork, and analysis of indicator datasets from the Kenya 2009 census. Key aquifers need urgent characterisation to reverse the current situation whereby development proceeds with insufficient aquifer knowledge. Private sector and public participation in management should be enhanced through decentralised management approaches. Water infrastructure and technologies should be fit-for-purpose in application and scale, and the pro-poor focus should be underpinned by appropriately focused management regimes.

This article investigates a stochastic filtering problem whereby the bor-rower’s hidden credit quality is estimated using ego-network signals. The hidden credit quality process is modeled as a mean reverting Ornstein-Ulehnbeck process. The lender observes the borrower’s behavior modeled as a continuous time diffusion process. The drift of the diffusion process is driven by the hidden credit quality. At discrete fixed times, the lender gets ego-network signals from the borrower and the borrower’s direct friends. The observation filtration thus contains continuous time borrower data augmented with discrete time ego-network signals. Combining the continuous time observation data and ego-network information, we derive filter equations for the hidden process and the properties of the conditional variance. Further, we study the asymptotic properties of the conditional variance when the frequency of arrival of ego-network signals is increased.

In our continuous search for cytotoxic compounds from the genus Zanthoxylum, chromatographic separation of the MeOH/CH2Cl2 (1:1) extract of Z. chalybeum yielded one new alkamide; 4-(isoprenyloxy)-3-methoxy-3,4-deoxymethylenedioxyfagaramide (1) and a known one; fagaramide (2). Similarly, from the MeOH/CH2Cl2 (1:1) extract of the stem bark of Z. parachanthum four known compounds; canthin-6-one (3), dihydrochelerythrine (4), lupeol (5) and sesamin (6) were isolated. Characterization of the structures of these compounds was achieved using spectroscopic techniques (NMR and MS). Using resazurin reduction assay 1, 3 and 6 displayed moderate cytotoxicity with IC50 values below 50 μM against the drug sensitive CCRF-CEM and multidrug-resistant CEM/ADR5000 leukemia cell lines. It is interesting to note that 3 was more active than the standard drug, doxorubicin against CEM/ADR5000 leukemia.

In our continuous search for cytotoxic compounds from the genus Zanthoxylum, chromatographic separation of the MeOH/CH2Cl2 (1:1) extract of Z. chalybeum yielded one new alkamide; 4-(isoprenyloxy)-3-methoxy-3,4-deoxymethylenedioxyfagaramide (1) and a known one; fagaramide (2). Similarly, from the MeOH/CH2Cl2 (1:1) extract of the stem bark of Z. parachanthum four known compounds; canthin-6-one (3), dihydrochelerythrine (4), lupeol (5) and sesamin (6) were isolated. Characterization of the structures of these compounds was achieved using spectroscopic techniques (NMR and MS). Using resazurin reduction assay 1, 3 and 6 displayed moderate cytotoxicity with IC50 values below 50 μM against the drug sensitive CCRF-CEM and multidrug-resistant CEM/ADR5000 leukemia cell lines. It is interesting to note that 3 was more active than the standard drug, doxorubicin against CEM/ADR5000 leukemia …

Antimony sulphide (Sb2S3) has drawn research interest due to its promising properties for photovoltaic applications. The progress in developing highly efficient Sb2S3 solar cells has stimulated this study to a great extent. In this paper, we present the results of a simulation of solar cell processing parameters on the performance of the solar cell through theoretical analysis and device simulation using SCAPS software. The results of this simulation show that the solar cell performance can be enhanced to a great extent by adjusting the thickness, doping concentration and defect density of both the TiO2 buffer layer and Sb2S3 absorber layer and also the electron affinity of the TiO2 buffer layer. Optimized parameters were found to be: doping concentration of (1.0 X 1017CM3 for TiO2 and 3.0 X 1016 CM3 for Sb2S3), defect density of the Sb2S3 absorber at (1.0 X 1015.....3) and the electron affinity of the buffer layer at (4.26 eV). The results obtained were as follows: Voc of 750 mV, Jsc of 15.23 mA/cm2, FF of 73.55% and efficiency of 8.41%. These results show that Sb2S3 is a potential earth-abundant compound that can yield highly efficient solar cells.

Abstract: The ability of commercial banks to provide market knowledge, transaction efficiency and contract
enforcement create demand for its services in the financial markets. Commercial banks operating in Kenya have
undertaken restructuring so as to be more competitive, to restore bank solvency, to increase the banking sector
capacity for financial intermediation and to improve financial performance. Previous researches done on the aspects
of bank restructuring and financial performance found conflicting results and some of them did not include the
intervening effect of deposits on this relationship. The study is informed by the theory of financial intermediation,
agency theory, and the institutional theory. This study sought to investigate the relationship between bank
restructuring, deposits and financial performance of commercial banks in Kenya. The population of the study was
the 44 commercial banks licensed and registered under the banking act to do business in Kenya but data availed
from financial statements of 39 commercial banks which were in operation for the period 2002 to 2014. Descriptive
and inferential data analysis methods were used to analyze the secondary data collected. The empirical findings
conclude that commercial banks use all the four types of bank restructuring which were financial, capital, operational
and asset restructuring. The findings of the first model revealed that capital restructuring, and asset restructuring
were the only variables found to have significant positive and negative influence respectively on the performance of
commercial banks in Kenya. In testing the second hypothesis, deposit were used as an intervening variable on the
relationship between bank restructuring and financial performance, where financial restructuring and capital
restructuring was found to significantly cause an increase in the profit margin of commercial banks while operational
restructuring and deposits were found to have a significant negative effect on bank profits. The composite variable
of financial services was not found to have a significant effect. Therefore, the research disclosed that operational
restructuring, and deposits did not influence banks profitability. The research concludes that the performance of most
commercial banks in Kenya is determined through restructuring banks’ financial and capital ratios The study
recommends that there is need to institute policy reforms geared towards viable restructuring and deposit
mobilization and that to continuously improve bank performance banks should encourage more borrowing and funds
from shareholders and banks need to continuously focus on restructuring rather than ownership.

Key Words: Bank Restructuring, Capital, Financial, Asset, Operational, Deposits.

Abstract:
In many economies world over, accountability and transparency as well as fiscal discipline in public expenditures take
priority as the main catalysts to economic growth. However, large fiscal deficits have been reported in most developing
countries which lead to inflation and currency devaluations. In this case, Kenyan government is no exception as its
expenditures are consistently way above its revenues. This study therefore attempted to assess the relationship between
government expenditure and fiscal deficit in Kenya. This study used a causal research design. Secondary data was
obtained from the financial records of National Bureau of Statistics, The Economic Surveys, Kenya Institute of Policy
Analysis and Research (KIPRA) and the Institute of Policy Analysis and Research (IPAR) ranging from year 2004/05 to
2010/11. Regression model was used to estimate the effect of government expenditure on fiscal deficits. The study
established that a unit increase in government expenditure, increases fiscal deficit of GDP. The study recommends that
the government of Kenya should come up with strong working policy to regulate the expenditure of its resources.

Effective effluent treatment is a paramount step towards conserving the dwindling clean water resources. The present study describes the use of crude protease extract from Bacillus Cereus Strain KM201428 biotransformation of azo dye Reactive Black 5 (RB5). Batch experimental results displayed over 97% decolorization efficiency with initial dye concentration of 1.0 x 10-4M. The decolorization process was highly dependent on contact time, dye concentration and pH. The optimum contact time and pH for decolorization were 120 hours and pH 9 respectively at 25˚C. Biotransformation of RB5 dye was monitored using UV-Vis spectrophotometer and formed metabolites characterized by LC–QTOF-MS. Comparison of resultant LC–QTOF-MS chromatograms after decolorization confirmed complete cleavage of RB5 dye. First order kinetic fitted well with experimental data for different RB5 dye concentrations

Background: Timely identification and management of intrapartum complications could significantly reduce maternal deaths, intrapartum stillbirths, and newborn deaths due to hypoxia. The World Health Organization (WHO) identifies monitoring of labor using the paper partograph as a high-priority intervention for identifying abnormities in labor and fetal well-being. This article describes a mixed-method, quasi-experimental study to assess the effectiveness of an Android tablet-based electronic, labor clinical decision-support application (ePartogram) in limited-resource settings.

Methods: The study, conducted in Kenya from October 2016 to May 2017, allocated 12 hospitals and health centers to an intervention (ePartogram) or comparison (paper partograph) group. Skilled birth attendants (SBAs) in both groups received a 2-day refresher training in labor management and partograph use. The intervention group received an additional 1-day orientation on use and care of the Android-based ePartogram app. All outcomes except one compare post-ePartogram intervention versus paper partograph controls. The exception is outcome of early perinatal mortality pre- and post-ePartogram introduction in intervention sites compared to control sites. We used log binomial regression to analyze the primary outcome of the study, suboptimal fetal outcomes. We also analyzed for secondary outcomes (SBAs performing recommended actions), and conducted in-depth interviews with facility in-charges and SBAs to ascertain acceptability and adoptability of the ePartogram.

Results: We compared data from 842 clients in active labor using ePartograms with data from 1,042 clients monitored using a paper partograph. SBAs using ePartograms were more likely than those using paper partographs to take action to maintain normal labor, such as ambulation, feeding, and fluid intake, and to address abnormal measurements of fetal well-being (14.7% versus 5.3%, adjusted relative risk=4.00, 95% confidence interval [CI]=1.95–8.19). Use of the ePartogram was associated with a 56% (95% CI=27%–73%) lower likelihood of suboptimal fetal outcomes than the paper partograph. Users of the ePartogram were more likely to be compliant with routine labor observations. SBAs stated that the technology was easy to use but raised concerns about its use at high-volume sites. Further research is needed to evaluate costs and benefit and to incorporate recent WHO guidance on labor management.

Conclusion: ePartogram use was associated with improvements in adherence to recommendations for routine labor care and a reduction in adverse fetal outcomes, with providers reporting adoptability without undue effort. Continued development of the ePartogram, including incorporating new clinical rules from the 2018 WHO recommendations on intrapartum care, will improve labor monitoring and quality care at all health system levels.

Githanga D. "The effects of aflatoxin exposure on Hepatitis B-induced immunity in Kenyan children." Curr Probl Pediatr Adolesc Health Care 2019. 2019:1-14. Abstractresearchgate

Background: Globally, approximately three million children die each year from vaccine preventable infectious diseases mainly in developing countries. Despite the success of the expanded immunization program, not all infants and children around the world develop the same protective immune response to the same vaccine. A vaccine must induce a response over the basal immune response that may be driven by population-specific, environmental or socio-economic factors. Mycotoxins like aflatoxins are immune suppressants that are confirmed to interfere with both cell-mediated and acquired immunity. The mechanism of aflatoxin toxicity is through the binding of the bio-activated AFB1-8, 9-epoxide to cellular macromolecules. Methods: We studied Hepatitis B surface antibodies [anti-HBs] levels to explore the immune modulation effects of dietary exposure to aflatoxins in children aged between one and fourteen years in Kenya. Hepatitis B vaccine was introduced for routine administration for Kenyan infants in November 2001. To assess the effects of aflatoxin on immunogenicity of childhood vaccines Aflatoxin B1-lysine in blood serum samples were determined using High Performance Liquid Chromatography with Fluorescence detection while anti-HBs were measured using Bio-ELISA anti-HBs kit. Results: The mean § SD of AFB1-lysine adducts in our study population was 45.38 § 87.03 pg/mg of albumin while the geometric mean was 20.40 pg/mg. The distribution of AFB1-lysine adducts was skewed to the right. Only 98/205 (47.8%) of the study population tested positive for Hepatitis B surface antibodies. From regression analysis, we noted that for every unit rise in serum aflatoxin level, anti-HBs dropped by 0.91 mIU/ml (¡0.9110038; 95% C.I ¡1.604948,¡0.21706). Conclusion: Despite high coverage of routine immunization, less than half of the study population had developed immunity to HepB. Exposure to aflatoxin was high and weakly associated with low anti-HBs antibodies. These findings highlight a potentially significant role for environmental factors that may contribute to vaccine effectiveness warranting further research.

Description
A systematic study of the photophysical and electrochemical properties of triscyclometalated homoleptic iridium(III) complexes based on 2-(1-naphthyl)pyridine (npy) ligands is presented. A systematic investigation of ligand substitution patterns showed an influence on the lifetime of the excited state, with slight changes in the absorption and emission spectral features. Specifically, the emission lifetime of a complex of an npy ligand substituted with a strongly electron-withdrawing trifluoromethyl group was longer than that of the corresponding complex with the electronically nonperturbed ligand (3.7 μs versus 1.5 μs). Electronically complementary ligands and complexes with orthogonal configurations showed slightly shorter excited state lifetimes compared with unsubstituted npy (1.4–3.0 μs). All complexes displayed reversible or quasireversible redox-couple processes, with the complex of the trifluoromethylated …

Although the role of ICTs in improving human life in Kenya is acknowledged widely, the focus of much
of ICT-related developments has been on human experiences at the level of disease and needs for
communication and mobility. Less obvious is how such technological interventions may be used to
address seemingly abstract yet grave concerns like climate change and its impact on the quality of human
life. This review paper, therefore, shall investigate the different situations where ICTs may be deployed
in relaying packaged and relevant localized climate information that can help rural farmers in Kitui
County, Kenya to make pertinent and timely decisions to improve their productivity and, ultimately, their
livelihoods. We hypothesize that rural communities' use ICT tools such as the mobile phones and the
community radios to access localized climate information (weather, seasonal forecasts, and agroadvisories)
and that livelihood assets and livelihood strategies positively change with the increasing
availability and use of the ICT-based climate information. The idea of the paper presented is to merge
theoretical and applied research outcomes to narrow the gap between the theory of ICTs usage and the
practice of it, while linking it to climate information and enhanced rural livelihood strategies. The review
of this paper shall be captured in social-scientific terms, and shall contribute to knowledge by helping
researchers and policymakers to determine climate information needs of rural ASAL communities,
knowledge on innovations related to ICTs, among others.

Abstract

Effect of formulated slow release NPK fertilizer [cellulose-graft-poly(acrylamide)/nanohydroxyapatite/soluble fertilizer] composite (SRF) on the performance and yield of maize, kale and capsicum was evaluated in a greenhouse experiment. No significant difference in growth parameters was observed between SRF and commercial fertilizer (CF) treatments. SRF recorded higher dry matter and yields relative to CF with similar application rates, though statistically insignificant. P deficiency was observed in maize at lowest SRF application rate of 45-57-17. N deficiency in CF was observed at the 8th week, but not in SRF with similar application rates during the same period. Kale showed both N and P deficiencies in the 7th week, while capsicum alone showed N deficiency in the 14th week in SRF at low application rates. NPK content in both maize and kale tissues, was significant between the amendments and control. Capsicum tissues had significantly (p ≤ 0.05) higher N content both in SRF and CF higher application rates of 125-159-45 & 100-100-100, respectively, compared to control. At final harvest, soil samples planted with maize and amended with the highest SRF rate showed significantly (p ≤ 0.05) higher P content, compared to lower rates and the control. The agronomic optimal rate of SRF determined by quadratic function were found to be higher than that of CF. SRF was found to enhance growth and yields of crops just like CF and could potentially have greater benefits such as improving soil health and resilience.

Renal Replacement Therapy Journal. 2019. AbstractWebsite

Introduction: Adherence to dietary prescriptions among patients with chronic kidney disease is known to prevent
deterioration of kidney functions and slow down the risk for morbidity and mortality. This study determined factors
associated with adherence to dietary prescription among adult patients with chronic kidney disease on hemodialysis.
Methods: A mixed-methods study, using parallel mixed design, was conducted at the renal clinics and dialysis units at
the national teaching and referral hospitals in Kenya from September 2018 to January 2019. The study followed a
QUAN + qual paradigm, with quantitative survey as the primary method. Adult patients with chronic kidney disease on
hemodialysis without kidney transplant were purposively sampled for the quantitative survey. A sub-sample of
adult patients and their caregivers were purposively sampled for the qualitative survey. Numeric data were collected
using a structured, self-reported questionnaire using Open Data Kit “Collect software” while qualitative data were
collected using in-depth interview guides and voice recording. Analysis on STATA software for quantitative and
NVIV0 12 for qualitative data was conducted. The dependent variable, “adherence to diet prescription” was analyzed as a
binary variable. P values < 0.1 and < 0.05 were considered as statistically significant in univariate and multivariate logistic
regression models respectively. Qualitative data were thematically analyzed.
Results: Only 36.3% of the study population adhered to their dietary prescriptions. Factors that were independently
associated with adherence to diet prescriptions were “flexibility in the diets” (AOR 2.65, 95% CI 1.11–6.30, P
0.028), “difficulties in following diet recommendations” (AOR 0.24, 95% CI 0.13–0.46, P < 001), and “adherence
to limiting fluid intake” (AOR 9.74, 95% CI 4.90–19.38, P < 0.001).
Conclusions: For patients with chronic kidney disease on hemodialysis, diet prescriptions with less restrictions
and requiring minimal extra efforts and resources are more likely to be adhered to than the restrictive ones.
Patients who adhere to their fluid intake restrictions easily follow their diet prescriptions. Prescribed diets should be based
on the individual patient’s usual dietary habits and assessed levels of challenges in using such diets. Additionally, diet
adherence messages should be integrated with fluid limitation messages. Further research on understanding patients’
adherence to fluid restriction is also suggested.

Description
Regarded as a frequent occurrence, disputes in construction projects occasioned by substandard communication of impractical clients’ expectations, defective works and delays in architectural designs significantly contribute to adverse effects on project results. Despite these and the numerous demerits linked to litigation majority of clients, contractors and construction consultants in Kenya still opt for it as opposed to Alternative Dispute Resolution (ADR) approaches to resolve disputes in construction projects. The purpose of this study was to establish the factors influencing use of alternative dispute resolution in construction projects in Imenti North Sub-County, Meru County, Kenya. In particular it examined the influence of: lack of awareness, preservation of business relationships, cost minimization and communication and documentation issues on the use of ADR in construction projects disputes. The research was guided by two theories; Theory of Planned Behavior and Transaction Cost Economics Theory and will be support by the Stair-Step Model of Dispute Resolution. The research embraced use of descriptive survey research design. Target population is of 255 respondents.

Generalized hyperbolic distribution and some of its subclasses like normal, hyperbolic and variance gamma distributions are used to fit daily log returns of eight listed companies in Nairobi Securities Exchange and Montréal Exchange. EM-based maximum likelihood estimation procedure is used to estimate parameters of the model. Kernel densities and empirical distribution of data are compared. The goodness of fit statistics of proposed distributions are used to measure how well model fits the data. Empirical results show that Generalized hyperbolic Distribution seems to improve partially, the geometric Brownian assumption on modeling returns of the underlying process, both in a developed and emerging market. Both markets seem to have different stochastic time

Ferrer N, Folch A, Lane M, Olago D, Odida J, Custodio E. "Groundwater hydrodynamics of an Eastern Africa coastal aquifer during the recent La Niña 2016-17 drought." Science of The Total Environment. 2019;661:575-597. AbstractWebsite

In 2016–17 much of East Africa was affected by a severe drought which has been attributed to Indian Ocean Dipole and El Niño Southern Oscillation conditions. Extreme events such as this have immediate and knock-on effects on water availability for household, agricultural and industrial use. Groundwater resources can provide a buffer in times of drought, but may themselves be stressed by reduced recharge and increased usage, posing significant challenges to groundwater resource management. In the context of East Africa, groundwater management is also hampered by a lack of information on aquifer characteristics. With the aim of addressing this knowledge gap, this study shows the hydrogeological behaviour before and during La Niña 2016/17 drought in southern coastal Kenya on a groundwater system which sits within a geological structure which is representative of an important portion of the East African coast. Diverse hydrochemical and isotopic campaigns, as well as groundwater head variation measurements, were carried out to study the groundwater hydrodynamics and thus characterize the aquifer system under climatic conditions before and during the La Niña event. This information is complemented with an estimation of changes in local recharge since 2012 using local data sets. The main consequence of the drought was a 69% reduction of recharge compared to an average climatic year. There was reduced recharge during the first rainy season (April–June) and no recharge during the second wet season (October–December). There was a concurrent increase in seawater intrusion even during the wet season.

Xu Y, Seward P, Gaye C, Lin L, Olago DO. "Groundwater in Sub-Saharan Africa." Hydrogeology Journal. 2019;27(3):815-822. AbstractWebsite

Sub-Saharan Africa (SSA; Fig. 1) refers to an area encompassing the countries in Africa that are fully, or partially, located south of the Sahara. The remaining African countries are generally referred to as belonging in North Africa. Although the socio-economic and hydrogeological conditions in SSA are diverse, they are sufficiently distinct (in general) from the conditions in North Africa to warrant being assessed separately—for example, high-yielding, high-storage, sedimentary aquifers are more common in North Africa than in SSA, while low-yielding, low-storage, basement aquifers are more widespread in SSA than in North Africa. The use of fossil groundwater is more typical in North Africa, while the use or renewable groundwater is more typical in SSA. Other hydrological characteristics associated with SSA include: groundwater resources that are generally under-utilized; lack of research and development that often prevents the optimal use of groundwater rather than over-development; and a heavy reliance by the rural and urban poor on shallow unconfined or semi-confined groundwater for potable water supplies, other domestic uses, and subsistence agriculture. Because of distinguishing characteristics such as these, there are good reasons for treating the hydrogeology of SSA as a whole, and separate from North Africa.

Background: The number of patients requiring renal replacement therapy (RRT) worldwide has been on the rise.
Vascular access is the lifeline for these patients when haemodialysis (HD) is the treatment of choice. Access-related
morbidity is a leading cause of hospitalization so that the function and patency of access are essential for the optimal
management of patients. There is a need to recognize when a vascular access is dysfunctional because intervention
must maintain function as well as preserve future vascular access sites.
Methods: This was a cross-sectional study that evaluated the haemodialysis vascular access function in patients
undergoing chronic haemodialysis at the Kenyatta National Hospital, Nairobi, Kenya. Peak access blood flow rates,
urea reduction ratio (URR) and Kt/V were analysed in 150 patients.
Results: The temporary (non-tunnelled) central venous dialysis catheters had poor function, with only 48%
achieving a mean blood flow rate > 300 mL/min. The comparable rate for arteriovenous fistulae (AVF) was 88%
and for tunnelled dialysis catheters 82%. One-quarter of the patients had a URR < 65%. Higher mean blood flow
rates were associated with higher URR (P = 0.004) and Kt/V (P = 0.009) values. AVF stenosis was present in 12.5%
and thrombosis in 3% of patients. Aneurysms were the commonest AVF complication (47%) but were not
haemodynamically significant.
Conclusions: Tunnelled haemodialysis catheters offered adequate blood flows and achieved adequate delivered
dialysis, comparable to arteriovenous fistulae. Non-tunnelled catheters delivered poor blood flow rates and dialysis
dose. Greater blood flow rates were associated with a higher delivered dialysis dose. There is a need for routine
surveillance and affordable interventional procedures to prevent loss of vascular access.

Non-alcoholic fatty liver disease (NFLD) is the hepatic manifestation of the metabolic syndrome recognized as the most prevalent chronic liver disease across all age groups. NFLD is strongly associated with obesity, insulin resistance, hypertension and dyslipidemia. Extensive research efforts are geared, through pharmacological approach, towards preventing or reversing this. Erythrina abyssinica Lam ex DC is an indigenous tree used widely used in traditional medicine, including for the treatment of liver related diseases, and has been shown to possess hypoglycemic, anti-oxidant, antimicrobial and anti-plasmodia effects. The present study is aimed at establishing the effects of E. abyssinica on the development of Non-alcoholic fatty liver disease induced by a high-fat and high-sugar diet in rats, in-vivo model. Methods: Forty rats (40) were randomly divided into five groups: positive control (pioglitazone), Negative control (high fat/high sugar diet), low test dose (200 mg/kg), high test dose (400 mg/kg) and normal group (standard chow pellets and fresh water). The inhibitory effect of the stem bark extract of E. abyssinica on the development of NAFLD was evaluated by chronic administration the herb extracts to rats on a high-fat/high-sugar diet. Biochemical indices of hepatic function including serum lipid profile, serum aspartate transaminase and alanine transaminase levels were then determined. Histological analysis of liver samples was carried out to quantify the degree of steato-hepatitis. Liver weights were taken and used to determine the hepatic index. The data was analyzed using one-way ANOVA, and Tukey9s post-hoc tests

Abstract

The industrialization process taking place in Africa has led to an overall increase in groundwater abstraction in most countries in the continent. However, the lack of hydrogeological data, as in many developing countries, makes it difficult to properly manage groundwater systems. This study presents a real case study in which a combination of different hydrogeological tools together with different sources of information allow the assessment of how increased competition for water may be affecting groundwater systems by analysing the sustainability of new abstraction regimes under different real climatic condition (before, during and after La Niña 2016). The area where this approach has been applied is Kwale County (in Coastal Kenya) in a hydrogeological context representative of an important part of the east coast of the continent, where new mining and agriculture activities co-exist with tourism and local communities. The results show that the lack of aquifer systems data can be overcome, at least partly, by integrating different sources of information. Most of the time, water-reliant users collect specific hydrogeological information that can contribute to defining the overall hydrogeological system, since their own main purpose is to exploit the aquifer with the maximum productivity. Therefore, local community water usage, together with different stakeholder's knowledge and good corporate water management act as a catalyst for providing critical data, and allows the generation of credible models for future groundwater management and resource allocation. Furthermore, complementary but simple information sources such as in situ interviews, Google Earth, Trip Advisor and easy-to use analytical methods that can be applied in the African context as in many developing countries, and enables groundwater abstraction to be estimated and the sustainability of the aquifer system to be defined, allowing potential future risks to be assessed.

Yohannis MA. ICTS As A Bridge Between Climate Information And Livelihood Strategies Among Rural Women In Kitui County, Kenya.; 2019. Abstract

The study was motivated by the increasing challenges of climate variability and climate change, which create problems, such as food insecurity in Kitui County in Kenya. In the current digital age, ICTs are core to all sectors to facilitate access to and enhance efficiency across various services. Although the role of ICTs in improving life in Kenya is widely acknowledged, the focus of most ICT-related developments has been on human experiences at the level of disease and needs for communication and mobility. Less obvious is how such technological interventions may be used to address seemingly abstract yet grave concerns like climate change and its impact on the quality of human life. This study, therefore, investigated the various scenarios where ICTs were deployed in relaying relevant localized climate information to help rural women farmers in Kitui County to make relevant decisions to improve their farm productivity and their livelihoods by extension. The study incorporated an ICT system to the Sustainable Livelihoods Framework (SLF) that consisted of Digital Capital and ICT Tools, thereby improving on the SLF. This modified SLF, mainstreamed ICT-driven climate information and provided the ideal means by which such information was leveraged to ensure enhanced sustainable livelihoods. Gender and Development (GAD) theory, Bourdieu’s ideas of social capital theory, and the Information Needs Assessment Model (INAM) further strengthened the SLF by addressing household power dynamics and climate information relevance in the rural communities. The research drew from emerging variables to demonstrate that regardless of the context in which the SLF was formulated, its versatility makes it the most appropriate tool for such studies in rural Kenya. The specific objectives of this study were threefold: (1) to assess the extent to which rural women access and use ICT tools in the utilization of climate information including weather, seasonal forecasts and agro-advisories; (2) to analyze the extent to which the use of ICT-based climate information by rural women influence maximize access and utilization of livelihood assets; and (3) to examine the livelihood strategies employed with the increasing availability and use of ICT-based climate information. The author adopted a mixed-methods approach for data collection and analysis that was guided by the SLF. Specific methods used, apart from on-desk review, were a household survey of 419 respondents, 14 key informant interviews, and two focus group discussions. The study merged theoretical and applied research outcomes to narrow the gap between the theory and practice of ICTs use while linking it to climate information and enhanced rural livelihood strategies. The outcome from the research findings highlighted the need for interventions to empower rural women in the use of ICT tools in exploiting the full potential of climate information, the need for tailoring modern scientific climate information to local needs, translated into simple formats and the local Kikamba language, the need for complementary services such as affordable credit, insurance, livelihood diversification opportunities and access to livelihood assets that can further strengthen their household resilience to climate variability. The results show that community radios combined with mobile phones are the most accessible and cost-effective ICT tools for rural women’s access to real-time, relevant climate and agro-advisory information. There is evidence that the women’s livelihood strategies have been enhanced which strengthened their livelihood assets, thereby improving their livelihoods under the wider rubric of the sustainable livelihood framework. The contribution to knowledge for this research was an enhanced SLF where the various responses and systematic analysis made the framework relevant in gaining insights into the link between climate information and livelihood strategies through ICTs among women in ii rural communities in Kitui. The modified framework and the research findings are also timely in light of the increasing realization of ICTs potential in contributing to climate change adaptation and mitigation. Also, the thesis builds on the growing body of literature that generated a rich repository that other researchers can use to advance knowledge, and the outcomes are eight peer-reviewed articles. The output of this study is replicable to other counties in Kenya because rural households depend on agriculture for their livelihood and this economic sector is not exempt to climate change and variability necessitating the need for local specific climate information. The recommendations to the research are that it can be extended to examine outcomes that will look at improved income, sustainable resource utilization, and food security, physical and emotional wellbeing. Further we provide policy recommendations and made suggestions to shape future climate change adaptation policies, plans, and strategies in Kenya that integrates gender equality into ICT and climate change to help farmers adapt to climate change/variability for sustainable development.
