A Framework for Accurate Drought Forecasting System Using Semantics-Based Data Integration Middleware

Published Conference ProceedingsTechnological advancement in Wireless Sensor Networks (WSN) has made it become an invaluable component of a reliable environmental monitoring system; they form the ‘digital skin’ through which to ‘sense’ and collect the context of the surroundings and provides information on the process leading to complex events such as drought. However, these environmental properties are measured by various heterogeneous sensors of different modalities in distributed locations making up the WSN, using different abstruse terms and vocabulary in most cases to denote the same observed property, causing data heterogeneity. Adding semantics and understanding the relationships that exist between the observed properties, and augmenting it with local indigenous knowledge is necessary for an accurate drought forecasting system. In this paper, we propose the framework for the semantic representation of sensor data and integration with indigenous knowledge on drought using a middleware for an efficient drought forecasting system

Number 4 - Silence! Peace in Progress : The 2013 Election and Peaceful Post-Election Dispute Management in Kenya

On March 4, 2013, Kenyans went to the polls to elect the president, vice-president, senators, county governors, and members of parliament. Tension was high; fears and uncertainties gripped the nation, and the international community watched with keen interest. Five years earlier, on December 27, 2007, a similar event had resulted in a horrific post-election violence (PEV) that left thousands dead and hundreds of thousands displaced, and that disrupted the economic and social conditions of the country and the entire sub-region. As the 2013 elections approached, the fear became palpable that there might be a recurrence. Those fears were unrealized; Kenya had an election that the Commonwealth Observer Group, among other observers, reported to be “credible” and to have met “many of the benchmarks for democratic elections to which Kenya is committed.” Based on a series of interviews conducted in Kenya in June-December 2013, this paper evaluates the factors that contributed to preservation of electoral and post-election peace (PEP) in Kenya

Cerebrospinal fluid ascites. a case report and literature review

Cerebrospinal fluid ascites is one complication of ventriculoperitoneal shunt surgery. This case reports a 7year old child with abdominal distention five years after ventriculoperitoneal shunt insertion for hydrocephalus secondary to aqueductal stenosis. The child had a history of multiple shunt revisions. Liver, cardiac and renal causes of ascites were diagnostically ruled out. Cerebrospinal fluid biochemistry was normal but ascitic fluid biochemistry and electrophoresis of the ascitic fluid were deranged. The ascites resolved gradually within two weeks of endoscopic third ventriculostomy. Cases recorded in literature are reviewed in the discussion

Snacking and its effect on nutritional status of adolescents in two national high schools in Nairobi Kenya

Snacking is defined as any intake of food or energy-containing beverage outside of breakfast, lunch and dinner (Bellisle, 2007). Previous studies have shown that snacking among adolescents is most common in the afternoon (Cross et al., 1994; Howarth et al., 2007). This study focused on snacking and its effect on dietary intake of macronutrients from normal school balanced meals and nutritional status of adolescents in two public national high schools namely Nairobi School for boys and Kenya High School (KHS) for girls, in Kenya. These schools were purposefully and randomly selected. A cross-sectional study on nutritional status and level of snacking was carried out involving 172 and 180 adolescent girls and boys respectively aged 13 to 18 years. A total of 352 adolescent high school girls and boys were assessed. A semi- structured questionnaire was used to collect quantitative data on socio-economic status (SES) of the respondents’ families while qualitative data were collected through focus group discussions, key informant interviews and observations. Anthropometric measurements on height and weight for nutritional status were used. Food consumption frequency was used to assess food intake from school meals and snacks. Energy and protein intake data were collected using a 24-hour recall based on a sub-sample of 31 students (14 boys and 17 girls). Eleven percent (11.0%) boys and 10.2% girls was stunted. Almost an equivalent number of both boys and girls (45.2% and 44.1% respectively) were found to be normal and nourished. Although, the girls are more likely to be stunted than boys stunting was not significantly different between the two groups and underweight was significantly higher in boys than in girls. Significantly more girls were overweight and obese than boys. Among the students who reported to be snacking, 10.4% were underweight and 76.9% had normal BMI-for-age as compared to those who did not snack where 20.0 % were underweight and 63.3% with normal BMI-for-age. It was observed that amongst those who snacked, an equal number of boys and girls at 5.2% were underweight while 6.9% more girls than boys (5.9%) were overweight. Most of the students who snacked had a normal (89.3%) height-for-age. Amongst those who snacked and based on gender, more boys (5.9%) than girls (4.8%) were found to be stunted. Among the gender the difference between those who snacked and those who didn’t was insignificant There were almost an equivalent percentage of those who snacked at 10.7% and those who didn’t at12.0% and were stunted. There was no significant difference between the BMI-for-age among those who were snacking and those who were not (?2=5.84, p value=0.120). Whether one snacks or not there is no significant relationship between snacking, BMI- for-Age, and hence nutritional status of both adolescent boys and girls in national boarding high schools. This study shows that snacking has no effect on adolescents’ nutritional status.   Key words: adolescent, snacking, high school, malnutrition, nutritional status, underweight, overweight, obese, stunting, githeri, ugal

How far are we from adhering to national asthma guidelines: The awareness factor

AbstractBackgroundThe Saudi national asthma protocol (SNAP) for asthma management was released in 1995 in an attempt to streamline asthma management practices in Saudi Arabia and improve the quality of care for asthma. Up to our knowledge, few studies assessed the adherence of Saudi physicians to the national asthma guidelines.ObjectivesThe objective of this present study was to assess the level of adherence of pediatricians and primary care physicians (PCPs) to the current SNAP recommendations and identify barriers to physician adherence.MethodologyThis is a cross-sectional study involving pediatricians and PCPs selected randomly from five major governmental hospitals in Riyadh, Saudi Arabia. Subjects were administered a self-administered questionnaire comprising 24 questions assessing their awareness of SNAP and their level of adherence to the recommendations.ResultsThe response rate was 38% (80/206). Out of most of the physicians who responded, 70% (56) were aware of SNAP, and only 78.2% (n=43) of them had modified their management of asthmatic patients according to the SNAP recommendations. The level of knowledge of the pharmacotherapy and diagnostic parts of the guidelines ranged between 41.5% and 90.7% in the pharmacotherapy part, and 53.7–59.6% in the diagnostic part. The most common barriers to adherence to SNAP were lack of awareness (25.2%), patient non- compliance (18.9%) and lack of resources (13.5%). There was no significant difference in awareness between pediatricians and PCPs (69.2%, 70.7% respectively).ConclusionThis study reveals a substantial gap between the actual care provided by pediatricians and PCPs to asthmatic patients and the recommendations formulated in the Saudi National Asthma Protocol (SNAP). Lack of awareness remains the most common barrier for adherence to the guidelines followed by patient non-compliance. To improve SNAP guideline adherence, tailored interventions that address barriers to adherence need to be implemented
