Wheat Farmers' Seed Management and Varietal Adoption in Kenya

Wheat is the second most important crop in Kenya after maize and is becoming an important source of food both for humans and livestock. Despite increasing wheat production, only 50% of domestic consumption requirements are being met. While the National Plant Breeding Research Centre at the Kenya Agricultural Research Institute has released more than 100 wheat varieties since it began operations in 1927, adoption has been slow in spite of better performance of new varieties. This study examined factors that influence farmers' adoption of new varieties in the Narok, Nakuru, and Uasin Gishu Districts that account for 80% of Kenya's domestic wheat production. The study found that most farmers in these Districts neither knew nor grew new wheat varieties, reflecting lack of seed and knowledge of these new varieties. Wheat varieties were also often not adopted in agroecological zones for which they were targeted. This should be an issue of concern to wheat breeders since varieties are currently bred specifically for agroecological zones. The main sources of wheat seed (old and new) for both small-scale and large-scale farmers were other farmers. The adoption of new wheat varieties was significantly higher among large-scale farmers in the high potential zone in Uasin Gishu District than among small-scale farmers in the low potential zone in Nakuru and Narok Districts. The logit model showed that experience in wheat farming had a positive impact on adoption of new wheat varieties. These factors will need to be taken into account by researchers, extension specialists, and policy makers.Crop Production/Industries,

Content of Vernacular Radio Stations Programs and Public Participation in Devolved Governance in Nyeri County, Kenya

Public participation in Kenyan counties still remains a mystery although many efforts have been put in place to achieve it. This is so because many county governments have documented use of public participation in governance without indicating a clear program to show how it is actualized. Media, including vernacular radio, is mentioned as one of the avenues for public participation but the question of how this happens remains unanswered. This study aimed to find out the influence of the content of vernacular radio stations programs on public participation in devolved   governance. The study employed a mixed method research design. The target population was 661,156 Nyeri County residents and officials of vernacular radio stations that have listenership in Nyeri. The pyramid method developed by Krejecie and Morgan was used to arrive at the sample size of 384 county residents while purposive sampling technique was used to select Kameme FM and its three officials. Data was collected through questionnaires and interview guides.  Quantitative data was analyzed using  descriptive and inferential statistical techniques through Statistical Package for Social Sciences while Content Analysis was used to analyse qualitative data. Graphs and tables were used for  presentations. The outcome was that there is a strong  positive correlation between content of Vernacular Radio Stations  Programs and public  participation in devolved governance. The study recommends that more attention be given to  content of these vernacular programs for they contribute to public participation ingovernance issues.Key words: Public participation, vernacular radio programs, devolved governance, Nyeri, Karatin

Wireless baby tracking system to curb child kidnapping

Thesis submitted in partial fulfillment of the requirements for the Degree of Master of Science in Information Technology (MSIT) at Strathmore UniversityChild kidnapping is common case, not only in Kenya but also all over the world. Infants are more vulnerable due to the fact that they are helpless and can easily be carried away without anyone noticing that something is amiss. Over time, different approaches have been developed to track children especially in public places. Many of these solutions involve GPS tracking but not many organizations and events involving gatherings of many children have been in a position to adopt such solutions. This is because they are expensive and do not integrate easily with other systems. The study seeks to come up with a solution to track babies within the workplace. It puts into consideration the “babies at work” policy, which has been adopted many companies including some in Kenya. The solution is based on RFID and basically combines active RFID tags with the existing wireless LAN. RFID has been greatly improved and the use of active RFID tags, which broadcast a signal to the access point, enables companies with an existing Internet connectivity to make use of their bandwidth without having to purchase RFID readers. The work is meant to provide a cheap and scalable solution that can traverse different scenarios, such as, public baby day-care centres, Churches and other social events. The proposed solution will be based on prototyping from the analysis phase to the implementation phase. The solution will then be tested to check on its reliability, performance and accuracy. The language to be used in development of the solution is PHP, Python, HTML, CSS, Javascript and MySQL database

Career Development and Employee Value Proposition People Management Future

Career development has gained a lot of interest over time as organizations and employees attempt to match individual goals with organizational goals to maximize performance. Value proposition, in human resource management focuses on the value that organizations and employees place on their worth, thereby the future of work for both. This chapter reviewed existing literature and linked the relationship between the two constructs to inform on their contribution to the future of people management. Global changes have made it necessary for employers and employees to re-examine the world of work and people management. How organizations manage employee careers is strategic in adding value to both the organization and the employees. The methodology employed was to search online and identify literature, review, and analysis were done per construct reviewed literature. Further the link between the career development and employee value proposition was identified. The limitation is that most of the available literature on the two constructs is before the Covid-19 pandemic and does not emphasize the future. The findings are that career though fast changing remains an important motivator for employees as an aspect of the employee value proposition that would impact people’s management futures

Identity Theft Mitigation in Kenyan Financial Sectors (SACCOs): Handwritten Signature Verification

The existence of identity theft in society has become a major concern due to the effects it causes to those that are affected by it, more especially in the financial sector. Thus this thesis establishes the existence of identity theft issues in the financial sector loan sections and proposes an algorithm that addresses the mitigation processes of identity theft by having the signatures on the loan forms verified using the implementation of the proposed algorithm, then the results are compared with the human experts verification that are done on a daily basis. From the qualitative data collected from the four SACCOs presented indicate the 93% of the respondents knew that forgery of one’s signature in the SACCO exists and from the 93%, 95% of them had been victims of identity theft and 50% of them knew it after deductions were been made from their accounts. The algorithm was implemented in a prototype that was used to test the signatures that were corrected from various individuals that belonged to various SACCOs. The prototype had successfully verified 80.1% of the test signatures and as expected the highest results from the four Human experts verification of forged signature was 8.3% indicating that they had indicated more signatures as originals. The prototype thus recorded an accuracy of 91.4% and a precision of 60.0%.

Factors associated with adequate weekly reporting for disease surveillance data among health facilities in Nairobi County, Kenya, 2013

Introduction: Kenya adopted the Integrated Disease Surveillance and Response (IDSR) strategy in 1998 to strengthen disease surveillance and epidemic response. However, the goal of weekly surveillance reporting among health facilities has not been achieved. We conducted a crosssectional study to determine the prevalence of adequate reporting and factors associated with IDSR reporting among health facilities in one Kenyan County. Methods: Health facilities (public and private) were enrolled using stratified random sampling from 348 facilities prioritized for routine surveillance reporting. Adequately-reporting facilities were defined as those which submitted >10 weekly reports during a twelve-week period and a poor reporting facilities were those which submitted <10 weekly reports. Multivariate logistic regression with backward selection was used to identify risk factors associated with adequate reporting. Results: From September 2 through November 30, 2013, we enrolled 175 health facilities; 130(74%) were private and 45(26%) were public. Of the 175 health facilities, 77 (44%) facilities classified as adequate reporting and 98 (56%) were reporting poorly. Multivariate analysis identified three factors to be independently associated with weekly adequate reporting: having weekly reporting forms at visit (AOR19, 95% CI: 6-65], having posters showing IDSR functions (AOR8, 95% CI: 2-12) and having a designated surveillance focal person (AOR7, 95% CI: 2-20). Conclusion: The majority of health facilities in Nairobi County were reporting poorly to IDSR and we recommend that the Ministry of Health provide all health facilities in Nairobi County with weekly reporting tools and offer specific trainings on IDSR which will help designate a focal surveillance person.Pan African Medical Journal 2016; 2

Comparison of equations for estimating glomerular filtration rate in screening for chronic kidney disease in asymptomatic black Africans: A cross sectional study

Background: Several equations have been developed to estimate glomerular filtration rate (eGFR). The common equations used were derived from populations predominantly comprised of Caucasians with chronic kidney disease (CKD). Some of the equations provide a correction factor for African-Americans due to their relatively increased muscle mass and this has been extrapolated to black Africans. Studies carried out in Africa in patients with CKD suggest that using this correction factor for the black African race may not be appropriate. However, these studies were not carried out in healthy individuals and as such the extrapolation of the findings to an asymptomatic black African population is questionable. We sought to compare the proportion of asymptomatic black Africans reported as having reduced eGFR using various eGFR equations. We further compared the association between known risk factors for CKD with eGFR determined using the different equations. Methods: We used participant and laboratory data collected as part of a global reference interval study conducted by the Committee of Reference Intervals and Decision Limits (C-RIDL) under the International Federation of Clinical Chemistry (IFCC). Serum creatinine values were used to calculate eGFR using the Cockcroft-Gault (CG), re-expressed 4 variable modified diet in renal disease (4v–MDRD), full age spectrum (FAS) and chronic kidney disease epidemiology collaboration equations (CKD-EPI). CKD classification based on eGFR was determined for every participant. Results: A total of 533 participants were included comprising 273 (51.2%) females. The 4v–MDRD equation without correction for race classified the least number of participants (61.7%) as having an eGFR equivalent to CKD stage G1 compared to 93.6% for CKD-EPI with correction for race. Only age had a statistically significant linear association with eGFR across all equations after performing multiple regression analysis. The multiple correlation coefficients for CKD risk factors were higher for CKD-EPI determined eGFRs. Conclusions: This study found that eGFR determined using CKD-EPI equations better correlated with a prediction model that included risk factors for CKD and classified fewer asymptomatic black Africans as having a reduced eGFR compared to 4v–MDRD, FAS and CG corrected for body surface area

Optimizing Linkage to Care and Initiation and Retention on Treatment of Adolescents with Newly Diagnosed HIV Infection.

Objective: Unsuccessful linkage to care and treatment increases adolescent HIV-related morbidity and mortality. This study evaluated the effect of a novel adolescent and youth Red Carpet Program (RCP) on the timing and outcomes of linkage to care. Design: A prepost implementation evaluation of the pilot RCP program. Settings: Healthcare facilities (HCFs) and schools in Homa Bay County, Kenya. Study participants: HIV-infected adolescents (15–19 years) and youth (20–21 years). Interventions: RCP provided fast-track peer-navigated services, peer counseling, and psychosocial support at HCFs and schools in six Homa Bay subcounties in 2016. RCP training and sensitization was implemented in 50 HCFs and 25 boarding schools. Main outcome measures: New adolescent and youth HIV diagnosis, linkage to and retention in care and treatment. Results: Within 6 months of program rollout, 559 adolescents and youths (481 women; 78 men) were newly diagnosed with HIV (15–19 years n = 277; 20–21 years, n = 282). The majority (n = 544; 97.3%) were linked to care, compared to 56.5% at preimplementation (P \u3c 0.001). All (100.0%; n = 559) adolescents and youths received peer counseling and psychosocial support, and the majority (n = 430; 79.0%) were initiated on treatment. Compared to preimplementation, the proportion of adolescents and youths who were retained on treatment increased from 66.0 to 90.0% at 3 months (P \u3c 0.001), and from 54.4 to 98.6% at 6 months (P \u3c 0.001). Conclusion: Implementation of RCP was associated with significant improvement in linkage to and early retention in care among adolescent and youth. The ongoing study will fully assess the efficacy of this linkage-to-care approach

Metabolic syndrome and its predictors in an urban population in Kenya: A cross sectional study

Background: The metabolic syndrome (MetS) is a clustering of interrelated risk factors which doubles the risk of cardio-vascular disease (CVD) in 5–10 years and increases the risk of type 2 diabetes 5 fold. The identification of modifiable CVD risk factors and predictors of MetS in an otherwise healthy population is necessary in order to identify individuals who may benefit from early interventions. We sought to determine the prevalence of MetS as defined by the harmonized criteria and its predictors in subjectively healthy black Africans from various urban centres in Kenya. Method: We used data collected from healthy black Africans in Kenya as part of a global study on establishing reference intervals for common laboratory tests. We determined the prevalence of MetS and its components using the 2009 harmonized criterion. Receiver operator characteristic (ROC) curve analysis was used to determine the area under the curves (AUC) for various predictors of MetS. Youden index was used to determine optimum cut-offs for quantitative measurements such as waist circumference (WC). Results: A total of 528 participants were included in the analysis. The prevalence of MetS was 25.6% (95% CI: 22. 0%–29.5%). Among the surrogate markers of visceral adiposity, lipid accumulation product was the best predictor of MetS with an AUC of 0.880 while triglyceride was the best predictor among the lipid parameters with an AUC of 0.816 for all participants. The optimal WC cut-off for diagnosing MetS was 94 cm and 86 cm respectively for males and females. Conclusions: The prevalence of MetS was high for a healthy population highlighting the fact that one can be physically healthy but have metabolic derangements indicative of an increased CVD risk. This is likely to result in an increase in the cases of CVD and type 2 diabetes in Kenya if interventions are not put in place to reverse this trend. We have also demonstrated the inappropriateness of the WC cut-off of 80 cm for black African women in Kenya when defining MetS and recommend adoption of 86 cm

Determination of reference intervals for common chemistry and immunoassay tests for Kenyan adults based on an internationally harmonized protocol and up-to-date statistical methods

Background: Due to a lack of reliable reference intervals (RIs) for Kenya, we set out to determine RIs for 40 common chemistry and immunoassay tests as part of the IFCC global RI project. Methods: Apparently healthy adults aged 18–65 years were recruited according to a harmonized protocol and samples analyzed using Beckman-Coulter analyzers. Value assigned serum panels were measured to standardize chemistry results. The need for partitioning reference values by sex and age was based on between-subgroup differences expressed as standard deviation ratio (SDR) or bias in lower or upper limits (LLs and ULs) of the RI. RIs were derived using a parametric method with/without latent abnormal value exclusion (LAVE). Results: Sex-specific RIs were required for uric acid, creatinine, total bilirubin (TBil), total cholesterol (TC), ALT, AST, CK, GGT, transferrin, transferrin saturation (TfSat) and immunoglobulin-M. Age-specific RIs were required for glucose and triglyceride for both sexes, and for urea, magnesium, TC, HDL-cholesterol ratio, ALP, and ferritin for females. LAVE was effective in optimizing RIs for AST, ALT, GGT iron-markers and CRP by reducing influence of latent anemia and metabolic diseases. Thyroid profile RIs were derived after excluding volunteers with anti-thyroid antibodies. Kenyan RIs were comparable to those of other countries participating in the global study with a few exceptions such as higher ULs for TBil and CRP. Conclusions: Kenyan RIs for major analytes were established using harmonized protocol from well-defined reference individuals. Standardized RIs for chemistry analytes can be shared across sub-Saharan African laboratories with similar ethnic and life-style profile
