Acquisition of Materials and Performance of Road Construction Projects in Kenya: A Case of Nairobi County
This study sought to establish the influence of acquisition of materials on performance of road construction projects in Kenya: A case of Nairobi County. The objective of the study was to establish the extent to which acquisition of materials influences performance of road construction projects in Kenya. This study was anchored on the theory of controlling, theory of construction management, and stakeholder theory. The paradigm used was pragmatism and the research approach used was mixed methods. Cross sectional descriptive survey and correlational research design were used. The sample size was 74 senior engineers which comprised 30 senior engineers from consulting engineering firms and 44 senior engineers from construction companies; 74 managing directors which comprised 30 managing directors from consulting engineering firms and 44 managing directors from construction companies. A five point Likert type scale questionnaire was used to collect quantitative data while interview guides were used to collect qualitative data. The statistical tools of analysis that were used for descriptive data were frequencies, percentages, arithmetic mean and standard deviation while the statistical tools that were used for inferential statistics were Pearson’s Product Moment Correlation and Linear Regression. The Fisher (F) test was used to test the hypotheses. The results indicated that with R²=0.246, F(6,40)=2.173, p=0.066>0.05, H1 was rejected and it was concluded that acquisition of materials had no statistically significant influence on the performance of road construction projects. However, establishment of quantities of materials required had a statistically significant influence on the performance of road construction projects. The study recommends that organizations that deal with road construction should have appropriate policies on establishment of quantities of materials required
Acute malnutrition recovery energy requirements based on mid-upper arm circumference: Secondary analysis of feeding program data from 5 countries, Combined Protocol for Acute Malnutrition Study (ComPAS) Stage 1.
BACKGROUND: Severe and moderate acute malnutrition (SAM and MAM) are currently treated with different food products in separate treatment programs. The development of a unified and simplified treatment protocol using a single food product aims to increase treatment program efficiency and effectiveness. This study, the first stage of the ComPAS trial, sought to assess rate of growth and energy requirements among children recovering from acute malnutrition in order to design a simplified, MUAC-based dosage protocol. METHODS: We obtained secondary data from patient cards of children aged 6-59 months recovering from SAM in outpatient therapeutic feeding programs (TFPs) and from MAM in supplementary feeding programs (SFPs) in five countries in Africa and Asia. We used local polynomial smoothing to assess changes in MUAC and proportional weight gain between clinic visits and assessed their normalized differences for a non-zero linear trend. We estimated energy needs to meet or exceed the growth observed in 95% of visits. RESULTS: This analysis used data from 5518 patients representing 33942 visits. Growth trends in MUAC and proportional weight gain were not significantly different, each lower at higher MUAC values: MUAC growth averaged 2mm/week at lower MUACs (100 to <110mm) and 1mm/week at higher MUACs (120mm to <125mm); and proportional weight gain declined from 3.9g/kg/day to 2.4g/kg/day across the same MUAC values. In 95% of visits by children with a MUAC 100mm to <125mm who were successfully treated, energy needs could be met or exceeded with 1,000 kilocalories a day. CONCLUSION: Two 92g sachets of Ready-to-Use Therapeutic Food (RUTF) (1,000kcal total) is proposed to meet the estimated total energy requirements of children with a MUAC 100mm to <115mm, and one 92g sachet of RUTF (500kcal) is proposed to meet half the energy requirements of children with a MUAC of 115 to <125mm. A simplified, combined protocol may enable a more holistic continuum of care, potentially contributing to increased coverage for children suffering from acute malnutrition
Epidémiologie moléculaire du rotavirus du groupe A associé aux gastroentérites chez les enfants de moins de 5 ans dans la ville de Yaoundé (Cameroun)
Le rotavirus est la première cause de gastroentérites grave chez les enfants de moins de 5 ans. La gravité et la mortalité de la maladie sont majorées dans les pays à revenus faibles d’Asie du sud et d’Afrique subsaharienne. Au Cameroun, la forte prévalence des rotaviroses, associées aux spécificités génotypiques locales du virus, soulignent l’importance de disposer de données épidémiologiques sur le virus. Cette étude visait à contribuer à une meilleure connaissance des principales souches de rotavirus responsables des gastroentérites chez les enfants de moins de 5 ans dans la ville de Yaoundé. Il s’agit d’une étude descriptive transversale d’une durée de 4 mois, dans 8 formations sanitaires de la ville de Yaoundé. Les échantillons de selles d’enfants de moins de 5 ans, hospitalisés pour gastroentérite ont été prélevés. La recherche du rotavirus s’est faite avec le kit ELISA Oxoid ProSpec TTM, et la détermination des génotypes du virus s’est faite par RT - PCR. Cent trente échantillons de selles d’enfants souffrant de gastroentérite ont été collectés. 66,1% de ces échantillons provenaient des hôpitaux FCB/CME, du CHE et de HDE. Le rotavirus a été isolé chez 30% des enfants, dont 40% avait entre 6 et 11 mois. Le CHE (6,9%) et l’HGY (0%) avaient respectivement la prévalence la plus élevée et la plus basse de la ville. Un nombre élevé de combinaisons génotypiques a été isolé, parmi lesquels prédominaient G1P[8] (31%) suivit de G3P[6] (28%) et de G4P[6] (13 %). Les génotypes mixtes G1P[6][8], G2P[6][8], et G1G3P[8] représentaient 22% des isolats. Un type G (3%) est resté indéterminé durant cette étude.© 2015 International Formulae Group.

Severity and mortality of this disease are majored in low-income countries of South - Asia and sub - Saharan Africa. In Cameroon, the high prevalence of rotaviruses associated to local genotypic specificities of virus enhances the importance of epidemiological database on the virus. This study aimed at contributing to a better knowledge of the main rotavirus strains responsible for gastroenteritis in children less than 5 years in Yaoundé. We carried out a descriptive and cross sectional study during 4 months, in 8 health centers in Yaoundé. Stool specimens were collected from children less than 5 years old, hospitalized for gastroenteritis. Rotavirus was detected with ELISA kit Oxoid ProSpecTTM, and genotypes determined by RT - PCR. One hundred and twenty seven stool specimens were collected during the study. FCB/CME, CHE, HDE provided 66.1% of specimens collected. Rotavirus was isolated in 30% of children, and 40% of these children were between 6 to 11 months old. The CHE (6. 9%) and the HGY (0%) had respectively the highest and the lowest prevalence of the town. A large number of genotype has been isolated and G1P[8] (31%) were predominant, followed by G3P[6] (28%) and G4P[6] (13%). Mixt genotypes G1P[6][8], G2P[6][8], and G1G3P[8] represented 22% of isolates. One G - type remained untypable.© 2015 International Formulae Group.

Understanding the relationship between cerebellar structure and social abilities
Background
The cerebellum contains more than 50% of all neurons in the brain and is involved in a broad range of cognitive functions, including social communication and social cognition. Inconsistent atypicalities in the cerebellum have been reported in individuals with autism compared to controls suggesting the limits of categorical case control comparisons. Alternatively, investigating how clinical dimensions are related to neuroanatomical features, in line with the Research Domain Criteria approach, might be more relevant. We hypothesized that the volume of the “cognitive” lobules of the cerebellum would be associated with social difficulties.
Methods
We analyzed structural MRI data from a large pediatric and transdiagnostic sample (Healthy Brain Network). We performed cerebellar parcellation with a well-validated automated segmentation pipeline (CERES). We studied how social communication abilities—assessed with the social component of the Social Responsiveness Scale (SRS)—were associated with the cerebellar structure, using linear mixed models and canonical correlation analysis.
Results
In 850 children and teenagers (mean age 10.8 ± 3 years; range 5–18 years), we found a significant association between the cerebellum, IQ and social communication performance in our canonical correlation model.
Limitations
Cerebellar parcellation relies on anatomical boundaries, which does not overlap with functional anatomy. The SRS was originally designed to identify social impairments associated with autism spectrum disorders.
Conclusion
Our results unravel a complex relationship between cerebellar structure, social performance and IQ and provide support for the involvement of the cerebellum in social and cognitive processes
Changes in the Fungal Microbiome of Maize During Hermetic Storage in the United States and Kenya
Prior to harvest, maize kernels are invaded by a diverse population of fungal organisms that comprise the microbiome of the grain mass. Poor post-harvest practices and improper drying can lead to the growth of mycotoxigenic storage fungi and deterioration of grain quality. Hermetic storage bags are a low-cost technology for the preservation of grain during storage, which has seen significant adoption in many regions of Sub-Saharan Africa. This study explored the use of high-throughput DNA sequencing of the fungal Internal Transcribed Spacer 2 (ITS2) region for characterization of the fungal microbiome before and after 3 months of storage in hermetic and non-hermetic (woven) bags in the United States and Kenya. Analysis of 1,377,221 and 3,633,944 ITS2 sequences from the United States and Kenya, respectively, resulted in 251 and 164 operational taxonomic units (OTUs). Taxonomic assignment of these OTUs revealed 63 and 34 fungal genera in the US and Kenya samples, respectively, many of which were not detected by traditional plating methods. The most abundant genus was Fusarium, which was identified in all samples. Storage fungi were detected in the grain mass prior to the storage experiments and increased in relative abundance within the woven bags. The results also indicate that storage location had no effect on the fungal microbiome of grain stored in the United States, while storage bag type led to significant changes in fungal composition. The fungal microbiome of the Kenya grain also underwent significant changes in composition during storage and fungal diversity increased during storage regardless of bag type. Our results indicated that extraction of DNA from ground kernels is sufficient for identifying the fungi associated with the maize. The results also indicated that bag type was the most important factor influencing changes in fungal microbiome during storage. The results also support the recommended use of hermetic storage for reducing food safety risks, especially from mycotoxigenic fungi
The Psychological Well-Being and Lived Experiences of LGBT Individuals with Fur Babies.
Pets are truly great companions. Some individuals feel that owning a pet can help them prepare for a growing
family by giving them a taste of what it would be like to have children. This study also looks into the
psychological well-being and life experiences of LGBT fur parents. Employing the Interpretative
Phenomenological Analysis, the findings of this study were: (1) With the presence of fur babies, participants
had the ease to overcome stressful events, especially the ones that affect their mental health. With these, they
have the desire to take care of their fur babies under all circumstances because they see their fur babies as
family members. Fur babies are excellent sources of motivation, confidence, and happiness for fur parents.
They are treated as family members because they contribute to the mental and emotional aspects of fur
parents. Moreover, the majority of respondents valued their pets far more than their actual family members,
however, some didn't spend as much time with their relatives and friends. This study comes to the
conclusion that a stronger bond with one's dog was also linked to higher anxiety about being unloved and
rejected by family members and people surrounding us, which was linked to a heavier impact on one's
psychological well-being. In reality, fur parents, especially LGBT parents, offer their fur babies a lot of love
and attention compared to other things
