The purpose of the study was to examine the relationship between market entry strategies and organisational performance of multinational corporations in Kenya. The specific objective is to establish the relationship between market entry strategies and organisational performance of multinational companies in Kenya. The study employed descriptive cross-sectional research design. The study established that market entry strategies explained 43.1% of the variance in organizational performance of multinational companies measured using financial performance parameters and 52.5% of the variance in organizational performance measured using nonfinancial parameters. The hypothesis that there is a significant relationship between market entry strategies and organisational performance was therefore supported. The study recommends that multinational corporations should carry out research on the market entry strategies before venturing into international market. This will ensure that they use the appropriate market entry strategy to enhance their performance. The study also recommended that the management evaluate the factors influencing the choice of market entry modes in order to choose the best alternative. The results makes a contribution to theory development, policy and marketing practice in relation to the effect of market entry strategy and organisation performance The limitation of the study is that it used top management as the respondents, may be if other cadre of employees were studied they could have contributed to more exhaustive results for generalization, this however did not compromise on study results. Therefore, the study suggests that there is room for further research incorporating a large population approach, using longitudinal designs and using group discussion to get more information from the respondents.

Introduction: In low-and middle-income countries (LMICs) where healthcare resources are often limited, making decisions on appropriate treatment choices is critical in ensuring reduction of paediatric deaths as well as instilling proper utilisation of the already constrained healthcare resources. Well-developed and validated prognostic models can aid in early recognition of potential risks thus contributing to the reduction of mortality rates. The aim of the planned systematic review is to identify and appraise the methodological rigor of multivariable prognostic models predicting in-hospital paediatric mortality in LMIC in order to identify statistical and methodological shortcomings deserving special attention and to identify models for external validation.
Methods and analysis: This protocol has followed the guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses for Protocols. A search of …

Description
Microplastic pollution has been recognized as a global threat in marine environments and a danger to prey, predators and humans. Yet there have been limited studies in the Western Indian Ocean (WIO) and along the Kenyan coast making it difficult to estimate the extent of such pollution. This is the first study on microplastics (MPs) in the surface waters within creeks (Tudor, Port-Reitz and Mida creeks) in Kenya. Sampling was done in January/February and September 2018 to collect microplastics from surface water. Neuston nets of 500 μm (large) and 250 μm (medium) size were towed for ten minutes and 50 litres of seawater sieved through a 20 μm net (small) in three replicates. The samples were digested in 10% Potassium Hydroxide, sieved, and then filtered with cellulose nitrate membrane microfilters. Concentrations of total microplastics, different shapes and colours were established under a microscope. High concentrations of small size (20-250 μm) MPs were encountered and Tudor and Port Reitz had higher concentrations compared to Mida Creek. The study provides data on microplastic concentrations within the creeks and recommends focussing on small size microplastics for monitoring purposes, which due to their high concentrations can be hazardous to organisms.

Nyambura M, Anne N. "Mobilization of Domestic Savings in Formal Financial Institutions: The Missing Link to Economic Growth. International Journal of Business and Social Science, Vol. 11 • No. 3 • March 2020.". 2020. Abstract

The purpose of the study was to examine factors that affect a Kenyan household’s decision to save in formal financial
institutions. This is because domestic saving finances investment and therefore economic growth. A non-experimental
research design was utilized using secondary data collected from a national-wide household survey in Kenya in 2009.
Cluster stratified probability sampling was used in selecting regions and households that were included in the survey.
A total of 6,598 households were used in the survey, using a questionnaire to gather information on financial access.
Descriptive and inferential statistics were used for data analysis. The results indicated the factors that influence
household’s decision to save in formal financial institutions were availability of loans, level of financial information,
location of household, sector of employment, expectations about future economic conditions, level of income, number
of banks in district of residence, transaction cost and time to nearest bank branch.
Keywords: household savings, formal financial institutions, economic growth,

Ronoh M, Chirove F, Wairimu J, Ogana W. "MODELING DISPROPORTIONAL EFFECTS OF EDUCATING INFECTED KENYAN YOUTH ON HIV/AIDS." Journal of Biological Systems. 2020;28(2):311-349. AbstractWebsite

We formulate an age and sex-structured deterministic model to assess the effect of increasing comprehensive knowledge of HIV/AIDS disease in the infected Adolescent Girls and Young Women (AGYW) and, Adolescent Boys and Young Men (ABYM) populations in Kenya. Mathematical analysis of infection through sub-network analysis was carried out to trace various infection routes and the veracity of various transmission routes as well as the associated probabilities. Using HIV data in Kenya on our model, disproportional effects were observed when dispensation of comprehensive knowledge of HIV/AIDS was preferred in one population over the other. Effective dispensation of comprehensive knowledge of HIV/AIDS in both the infected AGYW and ABYM populations significantly slows down the infection spread but may not eradicate it.

Pokhariyal GP. "Modeling influence of business excellence parameters on sustainable high performance of organizations." International Journal of Statistics and Applied Mathematics. 2020;5(3):134-139. AbstractWebsite

Organizations aspire to have sustainable high performance in order to have competitive advantage in the
market. Business excellence models provide frameworks to be applied by organizations in order to
develop thoughts, so that adequate actions be taken in a systematic and structured way to accomplish
sustainable high financial as well as non-financial performance. Various business excellence models
proposed by organizations as well as researchers are discussed. In this paper a mathematical model is
proposed in which independent variables are: top management team characteristic, mission vision and
core values, technology and innovation, and customer focus. Motivation and culture are moderating
variables. Government policies and global economy are intervening variables. The financial and nonfinancial performance, are dependent variables. The proposed model would yield corresponding
regression equations, representing stated hypotheses to be tested for the collected data from the field for
the chosen business organization. Further correlation coefficient can also be computed to check the
relationship between variables. From the estimated regression equations, through various tests, the
elasticity of the coefficients of model parameters and their statistical significance can be investigated.
Adequate recommendations can then be made to achieve the sustainable high performance for the
selected organization.

Since the outbreak of pandemic COVID-19 (Corona virus), many countries have continued to suffer
economically leading to massive losses in terms of trillions of dollars globally in terms of trade loses. In reaction to
this effect, many countries in the world have taken emergency measures to ensure that the impact does not lead to
huge economic and financial implications in terms of rapid recession. In Africa, where many countries have taken
measures to deal with global recession to the citizens especially through fiscal and monetary policies, which includes
Kenya. In addition, the social economic statues have continued to change instantaneously and stochastically
more so after huge number of populations losing their daily informal jobs with new measures to stop the spread of
COVID-19 virus. This paper seeks to model the effect of COVID-19 pandemic on Kenyan Gross Domestic Product
(GDP) contributors using a Discrete-time Markov Chain Analysis. In addition, the paper seeks to find the ultimate
effect of the Covid-19 to the top five key sectors of the Kenyan economy that contributes massively to GDP growth
by looking at the proportion of the contributors at steady state. Moreover, the results from this paper should help the
government of Kenya as well as global investors to understand different economic stimulus planning packages to
launch in the “hard-hit” sectors of the economy to reduce the impact of the potential economic recession. Ultimately,
the information should be help in formulating a post COVID-19 economic recovery plan for the Kenyan economy
but also act as a benchmark strategy for many other countries in Africa that has economic and financial dynamics
similar to that of Kenya

Joab Odhiambo, Weke P, Wendo J. "Modeling of Returns of Nairobi Securities Exchange 20 Share Index Using Log-Normal Distribution ." Research Journal of Finance and Accounting. 2020;11(8). AbstractWebsite

Nairobi Securities Exchange 20 Index Share (NSE-20 Share Index/ An Exchange Traded Fund) has been one of
the investment avenues for both Kenyans and foreign investors look whenever they want to make sound
investments decisions in the market. However, the assumption that the daily securities index prices follows a
normal distribution has been disputed by data in several cases. This means new statistical distributions must be
used to discern the distribution of NSE-20 Share Index thus enabling investors make prudent financial decisions
to avoid financial loses. In this research paper, we will model the prices of daily securities index using a log-normal
distribution. This is because the distribution follows a positive trend before we can ascertain on how well it fits
the already available data at the NSE market. This research paper recommends that a log-normal distribution best
fits data of the daily prices of NSE-20 Share Index for those investors who would like to model the future of the
market before making financial decisions.

Since the inception of the novel Corona Virus Disease-19 in December in China, the spread has been massive leading World Health Organization to declare it a world pandemic. While epicenter of COVID-19 was Wuhan city in China mainland, Italy has been affected most due to the high number of recorded deaths as at 21st April, 2020 at the same time USA recording the highest number of virus reported cases. In addition, the spread has been experienced in many developing African countries including Kenya. The Kenyan government need to make necessary plans for those who have tested positive through self-quarantine beds at Mbagathi Hospital as a way of containing the spread of the virus. In addition, lack of a proper mathematical model that can be used to model and predict the spread of COVID-19 for adequate response security has been one of the main concerns for the government. Many mathematical models have been proposed for proper modeling and forecasting, but this paper will focus on using a generalized linear regression that can detect linear relationship between the risk factors. The paper intents to model and forecast the confirmed COVID-19 cases in Kenya as a Compound Poisson regression process where the parameter follows a generalized linear regression that is influenced by the number of daily contact persons and daily flights with the already confirmed cases of the virus. Ultimately, this paper would assist the government in proper resource allocation to deal with pandemic in terms of available of bed capacities, public awareness campaigns and virus testing kits not only in the virus hotbed within Nairobi capital city but also in the other 47 Kenyan counties.

This research was focused on assessing how monitoring and evaluation work plan influence provision of curative and preventive tuberculosis healthcare practices in institutions of public health in Kisumu County, Kenya. The study unit of analysis was public health institutions that practice M&E system on provision of health care services. The target population consisting of doctors, M&E officers, clinical officers, nurses and patients in four public health institutions in Kisumu county, Kenya. The study was guided by pragmatism paradigm. A descriptive survey research design was employed to collect both quantitative and qualitative data and correlational design was used to test the hypothesis. A sample of 221 respondents was selected from a population of 517 using stratified random sampling. A structured questionnaire with both open and close ended with Likert type on 1-5 five point scale and interview schedule was used to collect data. A descriptive survey research design was employed to collect both quantitative and qualitative data and correlational design was used to test the hypothesis. Quantitative data was analyzed using descriptive and inferential statistics and data presented in frequency tables using means and standard deviations while qualitative data was presented in in narrative statements. Hypothesis was tested using linear regression at 0.05 level of significance to determine the degree and direction of relationships among variables. The study attained reliability of instruments using Cronbach Alpha coefficient of 0.735 for all items implying that the instrument was reliable. The results indicated that showed that M&E work plan regression was (r2=0.028, p<0.05). The study results indicated that present results for quantitative data based on composite mean score of 3.90 and 0.447 standard deviation for this variable. M&E system therefore, contributes significantly to the effective provision of curative and preventive tuberculosis health care services in public health institutions

Diversification of assets by an investor offers reduced exposure to risk compared to investing in a single asset. A multi-asset option gives an investor this advantage as its payout depends on the overall performance of several underlying assets. This study uses an information-based model to derive an approximate price for European call multi-asset options. The single asset price is derived using the risk-neutral pricing approach, and the multi-asset case uses the notion of comonotonicity. A numerical illustration is looked at to validate the theoretical results and to show the accuracy of the information-based model. The results show that prices from the information-based model provide a close fit to the empirical prices using a suitable information flow rate parameter. Hence, by making use of the information available in the market, an investor can price multi-asset European call options.

Mwazighe FM. "Multi-walled Carbon Nanotubes Modified Glassy Carbon Electrode for the Detection of Anthracene." Int. J. of Electrochem.Sci. . 2020;15(11):11058-11069. Abstract

The electrochemical oxidation of anthracene on a bare glassy carbon electrode results in electrode fouling and reduced sensitivity in its detection. Multi-walled carbon nanotubes were used to modify a glassy carbon electrode for the electrochemical detection of anthracene because of their antifouling and peak enhancement properties. The peak current for anthracene oxidation was enhanced by 73.64%, and the peak potential shifted by 53 mV to a slightly less positive value. The electrochemical process was determined to be mixed diffusion- and adsorption-controlled, and a preconcentration or accumulation time was necessary in the analysis of anthracene. Square wave voltammetry was used to analyze increasing concentrations of anthracene; a dynamic linear range of 50–146 μM (R2 = 0.98452) and a limit of detection of 42 μM were established. The sensor platform was used to detect anthracene in a spiked sample of tap water, albeit at lower than expected concentrations because of its low solubility in water.

"Multidisciplinary approach towards training of the next generation of forensic DNA analysts in Africa; a Kenyan perspective." Forensic Science International: Synergy. 2020;2:123-125. Abstract1-s2.0-s2589871x20300267-main.pdfWebsite

The uptake of forensic DNA testing technologies in Africa has been slow despite the revolutionary technology being discovered and adopted 3 decades ago. African governments and partners have invested in construction and equipping of forensic laboratories in Africa but the benefits are yet to be realised as the laboratories are still faced with the challenge of shortage of adequately trained personnel. This paper describes an innovative multidisciplinary training approach that was developed and used to train officers from the Directorate of Criminal Investigations Kenya. We report on the structure, implementation and effectiveness of the training. It is expected that with the increased number of trained forensic DNA analysts, there will be an improvement in quality of forensic DNA evidence presented in courts and a reduction in backlog in the forensic biology laboratories in Kenya.

PURPOSE: This study compares a web-based teleophthalmology assessment with a clinical slit lamp examination to screen for diabetic retinopathy (DR) and age-related macular degeneration (AMD) among diabetic patients in a rural East African district.
METHODS: Six hundred and twelve eyes from 306 diabetic patients underwent both a clinical slit lamp examination and a teleretina (TR) assessment by an experienced ophthalmologist. Both assessments were compared for any DR and AMD using the early treatment diabetic retinopathy study and age-related eye disease study grading scales, respectively.
RESULTS: Of the 612 TR assessment photos, 74 (12%) were deemed ungradable due to media opacities, poor patient cooperation, or unsatisfactory photographs. The ability to detect DR and AMD showed a fair agreement (kappa statistic 0.27 and 0.23, respectively) between the TR and clinical slit lamp examination. Relative to a clinical slit lamp evaluation, a positive TR diagnosis carried a 75.0% positive predictive value when diagnosing DR and a 27.3% positive predictive value when diagnosing AMD. A negative TR diagnosis carried a 97.2% negative predictive value for the diagnosis of DR and a 98.1% negative predictive value for the diagnosis of AMD.
CONCLUSION: When comparing TR assessments to clinical slit lamp examinations to diagnose DR and AMD, there was a fair agreement. Although further validation is needed, the TR approach provides a promising method to diagnose DR and AMD, two major causes of ocular impairment worldwide.

Keywords: Age-related macular degeneration, diabetic retinopathy, slit lamp examination, teleretina, teleophthalmology

This study sought to determine nutrition knowledge and its association with practices in management of stage 5 chronic
kidney disease (CKD) among renal adult patients in Kenyatta National Hospital. A cross-sectional analytical design was used to
facilitate collection of qualitative and quantitative data and enable identification of associations between variables. Cochran formula
was used to calculate a sample of 110 respondents. A research administered questionnaire with closed ended questions was used to
collect information. Descriptive statistics such as frequency and percentage were used to describe demographic and socio-economic
characteristics of the population. Inferential statistics were done using chi square with an alpha of 0.05 to test association between
independent and dependent variables. Most participants had moderate knowledge levels whereas more than half of the participants
(66%) indicated poor nutrition management practices of their condition. There was significant association between period on dialysis
in months and practices in management of stage 5 chronic kidney disease. Knowledge on importance of diet in management of stage 5
CKD (<0.001), moderation of fluid intake (<0.001), reduction in salt/ sodium intake (<0.001), and moderation in protein intake
(<0.004) were significantly associated with nutritional management practices of stage 5 CKD. The study concluded that Knowledge
levels were low in identifying foods rich in phosphorus, calcium and fat soluble vitamins. Practice scores were also poor despite
moderate nutrition knowledge levels. Patients’ knowledge on nutrition management of their condition may be achieved through
frequent and consistent nutrition education and counseling including follow ups.
Key Terms: Knowledge, Practice, chronic kidney disease, nutrition management

It is a well-known result in operator theory that whenever two operators are similar then they have equal spectra even though they do not have to belong to the same class of operators. However under a stronger relation of unitary equivalence it can be shown that two unitarily equivalent operators may belong to the same class of op erators. In this paper we endeavor to exhibit results on such classes of operators which belong to same class under unitary equivalence.

Abstract
Kenyan communities are exposed to natural disasters by an amalgamation of factors such as poverty, aridity, and settlements in areas susceptible to natural disasters or in areas with poor infrastructure. This is expected to increase due to the effects of climate change. In an attempt to explain some of these variabilities, we model the extreme damages from natural disasters in Kenya by developing a compound distribution that takes into account both the frequency and the severity of the extreme events. The resulting distribution is based on a threshold model and compound extreme value distribution. For frequency of events exceeding a threshold of 150,000, we found that it follows a negative binomial distribution, while severity of exceedance follows a generalized Pareto distribution. This distribution fits the data well and is found to be a better model for natural disasters in Kenya than the traditional extreme value threshold model.

Itis a known fact in operator theory that two similar operators have equal spectra but they do not necessarily have to belong to the same class of operators. However,under the stronger relation of unitary equivalence it can be shown that two unitarily equivalent operators may belong to the same class of operators. In this paper we endeavor to exhibit some results on some pairs of operators which may belong to the same class under not only unitary equivalence but also isometric and co-isometric equivalence

"Origin and evolution of dengue virus type 2 causing outbreaks in Kenya: Evidence of circulation of two cosmopolitan genotype ." Virus Evol. 2020;6(1):veaa026. Abstractveaa026.pdfWebsite

Dengue fever (DF) is an arboviral disease caused by dengue virus serotypes 1-4 (DENV 1-4). Globally, DF incidence and disease burden have increased in the recent past. Initially implicated in a 1982 outbreak, DENV-2 recently reemerged in Kenya causing outbreaks between 2011 and 2014 and more recently 2017-8. The origin and the evolutionary patterns that may explain the epidemiological expansion and increasing impact of DENV-2 in Kenya remain poorly understood. Using whole-genome sequencing, samples collected during the 2011-4 and 2017-8 dengue outbreaks were analyzed. Additional DENV-2 genomes were downloaded and pooled together with the fourteen genomes generated in this study. Bioinformatic methods were used to analyze phylogenetic relationships and evolutionary patterns of DENV-2 causing outbreaks in Kenya. The findings from this study have shown the first evidence of circulation of two different Cosmopolitan genotype lineages of DENV-2; Cosmopolitan-I (C-I) and Cosmopolitan-II (C-II), in Kenya. Our results put the origin location of C-I lineage in India in 2011, and C-II lineage in Burkina Faso between 1979 and 2013. C-I lineage was the most isolated during recent outbreaks, thus showing the contribution of this newly emerged strain to the increased DENV epidemics in the region. Our findings, backed by evidence of recent local epidemics that have been associated with C-I in Kenya and C-II in Burkina Faso, add to the growing evidence of expanding circulation and the impact of multiple strains of DENV in the region as well as globally. Thus, continued surveillance efforts on DENV activity and its evolutionary trends in the region, would contribute toward effective control and the current vaccine development efforts.

The possibility of obtaining thermal energy from the sun for household bathing and washing has resulted to growth in market for solar thermal applications with new types of solar absorbers currently being investigated either to compliment or to replace existing ones. This study focuses on CuFeMnO4 absorber paint by addressing aspects which have little attention regarding improvement of optical absorption for higher efficiency such as texturing the metal substrates on which to coat CuFeMnO4 absorber paint. In this study, texturing was done controllably in order to match the incoming solar radiation wavelength and the surface topography and morphology. Textured and untextured aluminum sheets coated with titanium dioxide (TiO2)-bound CuFeMnO4 absorber paint were used to fabricate prototype flat plate solar thermal collectors. Titanium dioxide (TiO2) was chosen here as binder to a spectrally selective CuFeMnO4 absorber paint. The TiO2-bound CuFeMnO4 absorber paint was applied by a simple, cheap and up-scalable dip coating method over the aluminum sheets. The aluminum sheets were electro-chemically textured to enhance optical absorption and photo-thermal conversion efficiency for both the textured and untextured prototypes were compared. The efficiency characterization of the prototype collectors was done by measuring the global solar irradiance, fluid inlet, fluid outlet and ambient temperature. Both instantaneous and steady-state efficiencies were determined mathematically, and it was found that the prototype collector whose absorber plates were textured recorded higher instantaneous and steady-state efficiencies compared to the collector fabricated from untextured aluminum plates.

Since cardiac structuring dimensions inform surgical decisions making, Z-score systematic error impairs surgical decision making and confounds outcome measurement, hence a similar error may affect the Nakata index. In this study, PubMed was searched using the terms: “pulmonary,” “artery,” “size,” “Nakata,” “Fontan,” and “outcome”. Studies that did not describe the outcome of the Fontan procedure and the size of the branch pulmonary arteries were excluded. Outcome measures of interest, in relation to BPA size, included: Operative mortality, Fontan “take-down”, length of ICU stay, pleural effusions and functional capacity. The results revealed that of 116 papers retrieved, 9 were included representing 1,042 patients who underwent the Fontan procedure. Six out of 9 papers representing 645 (61.9%) patients reported that BPA size had no relationship with the outcome of the Fontan procedure; while 2 out of 9 papers representing 366 (35.1%) patients found that BPA size did affect the outcome. One paper representing 31 (3%) patients was unable to find any relationship. All the papers that concluded that there was no relationship labelled normal sized BPAs as small because of a systematic error introduced by the Nakata index. Papers that found a relationship did not use the Nakata index. Thus, Nakata index systematic error may impair surgical decision making and confound outcome measurement in Fontan surgery. In addition, continued use of the Fontan index may have similar implications for other congenital heart lesions.

BACKGROUND: Influenza viruses remain a global threat with the potential to trigger outbreaks and pandemics. Globally, seasonal influenza viruses' mortality range from 291 243-645 832 annually, of which 17% occurs in Sub-Saharan Africa. We sought to estimate the overall prevalence of influenza infections in Kenya, identifying factors influencing the distribution of these infections, and describe trends in occurrence from 2007 to 2013. METHODS: Surveillance was conducted at eight district hospital sites countrywide. Participants who met the case definition for influenza-like illness were enrolled in the surveillance program. The nasopharyngeal specimens were collected from all participants. We tested all specimens for influenza viruses with quantitative reverse transcriptase real-time polymerase chain reaction (RT-qPCR) assay. Bivariate and multivariate log-binomial regression was performed with a statistically significant level of p<0.005. An administrative map of Kenya was used to locate the geographical distribution of surveillance sites in counties. We visualized the monthly trend of influenza viruses with a graph and chart using exponential smoothing at a damping factor of 0.5 over the study period (2007-2013). RESULTS: A total of 17446 participants enrolled in the program. The overall prevalence of influenza viruses was 19% (n = 3230), of which 76% (n = 2449) were type A, 21% (n = 669) type B and 3% (n = 112) A/ B coinfection. Of those with type A, 59% (n = 1451) were not subtyped. Seasonal influenza A/H3N2 was found in 48% (n = 475), influenza A/H1N1/pdm 2009 in 43% (n = 434), and seasonal influenza A/ H1N1 in 9% (n = 88) participants. Both genders were represented, whereas a large proportion of participants 55% were

Background: Chronic Kidney Disease (CKD) is a global health problem with an increase in prevalence especially
in Sub-Saharan Africa (SSA). It has a high morbidity and mortality. CKD and osteoarthritis (OA) are related as
they both increase with age and are associated with comorbidities e.g. hypertension, obesity etc. However,
there is limited evidence on the prevalence and associated risk factors of CKD among OA patients.
Objective: To assess the prevalence and factors associated with CKD in OA patients attending Rheumatology
and Orthopaedic clinics at Kenyatta National Hospital.
Design: A hospital-based descriptive cross-sectional study.
Methods: The study was conducted between November 2019 and January 2020 involving patients aged 18
years and above; being followed up in the rheumatology and orthopaedic clinics at Kenyatta National Hospital
with a diagnosis of knee, hip, spine and hand osteoarthritis based on the American College of Rheumatology
criteria. Chronic kidney disease was defined as an eGFR of less than or equal to 60 ml/min/1.73m2
and/or
proteinuria of 30 mg/dl detected on urinary dipstick for three months or more. Descriptive statistics were
used to describe the participants. Association between participants’ characteristics and CKD prevalence were
assessed using chi-square and factors associated with CKD among OA patients using bivariate and multivariable
logistic regressions.
Results: The overall prevalence of CKD among patients with osteoarthritis was 61.9% (56.4–66.3) as per eGFR
using Cockrauft Gault (CG). Most were in CKD stage 3 at 59.2% with 45.5% in G3a and 13.7% in G3b. One point
one percent were in stage 1, 38.3% in stage 2 and 1.4% were in CKD stage 4 and 5. Only 12.1% of the respondents
had persistent proteinuria and thus most of the patients had low and moderate risk for CKD progression at
38% and 38.2% respectively. Only 12.1% and 11.6% had high and very high risk for CKD progression. The CKD
prevalence increased with age, being highest among older adults (65+ years). The prevalence was higher
among men than women (65.9%, 95% CI: 54.7–75.5 vs. 60.2%, 95% CI: 54.4–65.7). The factors associated with
CKD in OA were old age, hypertension and poor and fair self-rated health which increased the odds of CKD
while moderate physical activity, overweight/obesity and use of more than one medication (NSAID/ACEI/ARB)
reduced the odds of CKD.
Conclusion: This study provides evidence that osteoarthritis is associated with a high prevalence of CKD.
However, most of the patients are asymptomatic and in low and moderate risk category based on Kidney
Disease Improving Global Outcomes (KDIGO) nomenclature. Osteoarthritis patients should be considered a
high-risk group for chronic kidney disease given their older age, chronic use of NSAIDs and high prevalence of
comorbidities e.g. hypertension, overweight/obesity which are known risk factors for CKD. Screening for CKD
in OA patients should therefore be done routinely as is the case in other high risk groups e.g. diabetes.

There is a tendency in Kenyan literature, which can be defined as ahistorical ethnopolitanism. In this approach the writer chooses to use names of characters and places that indicate an attempt to see the Kenyan community from a distance. The result is that, in the push for inclusivity in works of literature, the very idea an authentic record of history and self-knowledge is lost: Real actors are alienated from the story of the history of the country; the background loses its referential significance; fantasy contexts are created to overlay and erase the real; and an atmosphere of namelessness is prioritised. This paper is a preliminary critique of these traits in contemporary Kenyan creative narrative. It seeks to highlight how such an approach – whose aim is to create a text that sidesteps ethnic politics – paradoxically undermines the writers’ efforts.

Proximate analysis of twenty fruits and vegetable waste from Nairobi County was evaluated. They were obtained from Kangemi and Wakulima markets. Standard procedures were used for the analysis of crude fat, protein,fiber, carbohydrates, moisture, ash, nitrogen-free extract and energy. The results obtained revealed that moisture content was in the range of 82.8 to 95.86% apart from sweet potato and banana which was 62.05 and 74.30% respectively. Protein range was between 0.57 to 3.49% with high-fat content being recorded in avocado at 9.03%. The ash content was highest
in comfrey at 3.46% and lowest in mango at 0.44%. The carbohydrate level obtained by the difference method was lowest in courgette at 1.99% with crude fiber ranging from 0.69 to 2.73%. The total calculated energy ranged from 1.94 to 39.98 Kcal/100g. The macro-nutrient concentrations were 3.59 and 1.53% for potassium and calcium respectively. Lead, iron and zinc were detected at 15.1±3.6, 3742±235 and 176±11 ppm respectively. There is the presence of proximate properties in the edible portion of wasted fruits and vegetable and therefore, this study recommends proper fruits and vegetable handling during harvest, transportation, storage and marketing. Besides, the unavoidable waste should be used as biomass in energy production to deal with landfilling issues in the market places.

AbstractProximity Density Assessment and Characterization of Water and Sanitation Facilities in the Informal Settlements of Kisumu City: Implications for Public Health Planningjstage.jst.go

Access to water and sanitation remain a challenge in many developing countries, especially in pro-poor
urban informal settlements where socioeconomic livelihoods are generally low. The aim of this study was to characterise the water and sanitation facilities in the informal settlements of Kisumu City and to evaluate their effect on
community hygiene and health. The study focussed on the five urban informal settlements of Nyalenda A, Nyalenda
B, Manyatta A, Manyatta B and Obunga, and the three Peri-urban informal settlements of Kogony, Usoma and
Otonglo. Using descriptive techniques, the researcher surveyed 114 water sources and all sanitation facilities within
0-15m and 15-30m radii of the water sources. The findings revealed dominance of shallow wells and traditional pit
latrines as the primary water sources and sanitation facilities, respectively. Out of the water sources studied, 87.7%
(100) were shallow wells (mean depth 1.5 m), 9.6% (11) springs and 2.6% (3) boreholes. Most of these shallow
wells (83%) were within the urban informal settlements where uses range from washing and cleaning, cooking, and
even drinking (13.5%), despite the majority being unprotected. The analysis of the density of sanitation facilities
near the water points showed that 32.3% existed within a 15m radius of the nearest water sources, in violation of
the recommended safe distance of 30m. With an increased density of toilets near critical water sources and other
sanitary practices, public health is highly compromised.

During the period 2011-2015, the Drug Analysis and Research Unit (DARU) analyzed 1972 drug samples. The samples consisted of 21.5% locally manufactured and 78.2% imported products while the origin of 0.3% of products was indeterminate. Samples were subjected to compendial and/or in-house analytical specifications. The overall non-compliance rate was 4.5% comprising 2.5% local products and 2.0% imports. High failure rates were recorded for uterotonics (37.5%), hemostatics (33%), anthelmintics (17%) and anticancers (10.5%) while ophthalmic, immunomodulatory, musculoskeletal and endocrine drugs all complied with the quality acceptance criteria. Erectile dysfunction drugs, received by the laboratory for the first time, all complied with specifications. The results obtained demonstrate an improvement in the quality of samples submitted to DARU when compared to previous performance.

Aims: As shown in literature, several authors have adopted various individual frailty mixing distributions as a way of dealing with possible heterogeneity due to unobserved covariates in a group of insurers. This research contribution is to generalize the frailty mixing distribution to nest other classes of frailty distributions not in literature and apply the proposed distributions in valuation of life annuity business.

Methodology: A simulation study is done to assess the performance of the aforementioned models. The baseline parameters is estimated using Bayesian Inference and a better model is suggested for valuation of life annuity business.

Results: As a result of generalizing the frailty some new classes of frailty distributions are constructed such as; the Reciprocal Inverse Gaussian Frailty, the Inverse Gamma Frailty, the Harmonic Frailty and the Positive Hyperbolic Frailty.

From the simulation study, the proposed new frailty models shows that ignoring frailty leads to an underestimation of future residual lifetime since the survival curve shifts to the right when heterogeneity is accounted for. This is consistent with frailty literature.

The Reciprocal Inverse Gaussian model closely represents the Association of Kenya Insurers graduated rates with a slight increase in survival due to longevity risk.

Conclusion: The proposed new frailty models show an increase in the insurers expected liability when unobserved heterogeneity is accounted for. This is consistent with frailty literature and thus can be applied to avoid underestimating the insurer’s liability in the context of life annuity business.

The RIG model as proposed in estimating future liability by directly adjusting the AKI mortality rates shows an increase in longevity risk. The extent of heterogeneity of the insured group determines the level of risk. The RIG frailties should be considered for multivariate cases where the insureds are clustered in groups.

Groundwater is the preferred alternative water source during times of shortages and in areas not served by piped water supplies. Pit latrines are the main sanitation facilities in Kisumu where sewerage extends over less than 20 per cent of the city. Pit latrines contribute to microbial contamination of shallow groundwater in Kisumu.

Description
A set of structurally related O-methylated flavonoid natural products isolated from Senecio roseiflorus (1), Polygonum senegalense (2 and 3), Bhaphia macrocalyx (4), Gardenia ternifolia (5), and Psiadia punctulata (6) plant species were characterized for their interaction with human monoamine oxidases (MAO-A and-B) in vitro. Compounds 1, 2, and 5 showed selective inhibition of MAO-A, while 4 and 6 showed selective inhibition of MAO-B. Compound 3 showed~ 2-fold selectivity towards inhibition of MAO-A. Binding of compounds 1–3 and 5 with MAO-A, and compounds 3 and 6 with MAO-B was reversible and not time-independent. The analysis of enzyme-inhibition kinetics suggested a reversible-competitive mechanism for inhibition of MAO-A by 1 and 3, while a partially-reversible mixed-type inhibition by 5. Similarly, enzyme inhibition-kinetics analysis with compounds 3, 4, and 6, suggested a competitive reversible inhibition of MAO-B. The molecular docking study suggested that 1 selectively interacts with the active-site of human MAO-A near N5 of FAD. The calculated binding free energies of the O-methylated flavonoids (1 and 4–6) and chalcones (2 and 3) to MAO-A matched closely with the trend in the experimental IC 50′ s. Analysis of the binding free-energies suggested better interaction of 4 and 6 with MAO-B than with MAO-A. The natural O-methylated flavonoid (1) with highly potent inhibition (IC 50 33 nM; Ki 37.9 nM) and> 292 fold selectivity against human MAO-A (vs. MAO-B) provides a new drug lead for the treatment of neurological disorders.

Kitata M. "Sexualising the performance, objectifying the performer: The twerk dance in Kenya." Agenda. 2020;34(3):11-21. Abstract

Shifting arenas of dance performance and youths’ counterculture have brought the twerk to the internet, thus exposing it to the discourse of cultural imperialism, appropriation, and cultural resistance. This has changed the symbolism of the art form: from a performance meant for celebration, to a dance of sexual rage. The media associates the dance with bottom provocation, prostitution or celebrity achievement stories − rarely celebrating the intellect, aesthetics or the expression of freedom in it. From a western point of view, twerking is overly sexualised and the performers participants in a cultural notoriety – thus, objectifying it. However, in its original context it is primarily a dance for festive celebrations. As a form of artistic expression resisting cultural destruction in Kenya, twerk is a way of re-politicising the African female body, and decolonising it from the male, western influenced gaze. Sexual expression in it is …

A fragmented digital agriculture ecosystem has been linked to the slow scale-out of digital platforms and other digital
technology solutions for agriculture. This has undermined the prospects of digitalizing agriculture and increasing sectoral outcomes in sub-Saharan African countries. We conceptualized an aggregator platform for digital services in agriculture as a special form of digital platforms that can enhance the value and usage of digital technologies at the industry
level. Little is known about how such a platform can create value as a new service ecology in agriculture. We set out to
examine the underlying structure and prioritizations of value creation sources in such a platform from the perspective
of likely users in Kenya. We used a parallel convergent mixed methods approach to the study. Confirmatory factor analysis of data from 405 respondents supported a two-factor structure, being an adaptation of the framework on value creation sources in e-Business by Amit, R., & Zott, C. (2001). We conceptualized the two factors as platform-wide efficiency
and loyalty-centeredness. User experience related search costs were most impactful on platform-wide efficiency, while
loyalty-centeredness was impacted most by providing guarantees for quality and reliability to platform users. Thematic
analysis of 369 qualitative responses obtained platform inclusivity - comprising value chain coverage and digital inclusivity,
as additional considerations for amplifying sector-wide benefits of an aggregator platform for digital services in agriculture. We discuss implications for policy and practice in the light of resource constraints and the promise to digitally
transform agriculture in SSA countries.
