Joint microwave and infrared studies for soil moisture determination

The feasibility of using a combined microwave-thermal infrared system to determine soil moisture content is addressed. Of particular concern are bare soils. The theoretical basis for microwave emission from soils and the transport of heat and moisture in soils is presented. Also, a description is given of the results of two field experiments held during vernal months in the San Joaquin Valley of California

Long-term mental health of war-refugees: a systematic literature review

BACKGROUND: There are several million war-refugees worldwide, majority of whom stay in the recipient countries for years. However, little is known about their long-term mental health. This review aimed to assess prevalence of mental disorders and to identify their correlates among long-settled war-refugees. METHODS: We conducted a systematic review of studies that assessed current prevalence and/or factors associated with depression and anxiety disorders in adult war-refugees 5 years or longer after displacement. We searched Medline, Embase, CINAHL, PsycINFO, and PILOTS from their inception to October 2014, searched reference lists, and contacted experts. Because of a high heterogeneity between studies, overall estimates of mental disorders were not discussed. Instead, prevalence rates were reviewed narratively and possible sources of heterogeneity between studies were investigated both by subgroup analysis and narratively. A descriptive analysis examined pre-migration and post-migration factors associated with mental disorders in this population. RESULTS: The review identified 29 studies on long-term mental health with a total of 16,010 war-affected refugees. There was significant between-study heterogeneity in prevalence rates of depression (range 2.3–80 %), PTSD (4.4–86 %), and unspecified anxiety disorder (20.3–88 %), although prevalence estimates were typically in the range of 20 % and above. Both clinical and methodological factors contributed substantially to the observed heterogeneity. Studies of higher methodological quality generally reported lower prevalence rates. Prevalence rates were also related to both which country the refugees came from and in which country they resettled. Refugees from former Yugoslavia and Cambodia tended to report the highest rates of mental disorders, as well as refugees residing in the USA. Descriptive synthesis suggested that greater exposure to pre-migration traumatic experiences and post-migration stress were the most consistent factors associated with all three disorders, whilst a poor post-migration socio-economic status was particularly associated with depression. CONCLUSIONS: There is a need for more methodologically consistent and rigorous research on the mental health of long-settled war refugees. Existing evidence suggests that mental disorders tend to be highly prevalent in war refugees many years after resettlement. This increased risk may not only be a consequence of exposure to wartime trauma but may also be influenced by post-migration socio-economic factors

Self-reported adherence to treatment: A study of socioeconomic factors and psychiatric morbidity among male and female patients with HIV infection in Sokoto, Nigeria

Objective: Adherence to treatment is important and relevant in HIV  treatment. Previous studies in sub Sahara Africa and south western Nigeria reported that psychiatric morbidity influence treatment adherence.The present study was to examine treatment adherence among the male and the female patients with HIV infection and the effect of socioeconomic factors and psychiatric morbidity on treatment adherence .Methods: A total of 159 patients which comprised of 48 male and 111  female who were eligible for this cross sectional prospective study were  included having given their consent to participate. Questionnaire relating to socioeconomic factors and treatment adherence were administered. Psychiatric morbidity was assessed using HADS. Data was analyzed with SPSS for windows version 16.0.Results: Treatment adherence was poor in 5.3% of the patients. The male patients had slightly better adherence than the female patients. Factors associated with poor treatment adherence include poor clinic attendance, presence of anxiety symptoms in males and poor education attainment in females.Conclusion: Treatment adherence is related to socioeconomic factors and psychiatric morbidity. Treatment protocol in which mental health and  detailed socioeconomic circumstance of patient is an integral part should be encouraged.Keywords: Adherence, HIV, infection, Patient, Treatmen

Food and vices in south-eastern Nigeria: implications for poverty

This study focused on food and vices in South-Eastern Nigeria: implication for poverty. One hundred and sixty (160) respondents, adult male and female, were selected from 8 local government areas in Imo and Abia States. A purposive sampling technique was employed. The objectives include among others an examination of the nature of poverty in South-Eastern Nigeria; an investigation to ascertain whether or not, poverty results in hunger, etc. The following were the findings: Hunger seems to have ravaged our society. This is because majority of our people are poor and are unable to solve the hunger problem. As a result of inability to provide food, which is a basic necessity of life, the poor have employed all sorts of measures to put food on the table for their families. Unfortunately, most of these measures have been negative; as people are engaged in vices like armedrobbery, prostitution, pick pocketing, over-profiteering, etc. Others, because of poverty, have engaged in begging, constituting nuisance in the society. This paper sought solutions that would improve the lot of the poor and have them properly engaged in activities other than these vices, which can help them provide food for their families. The following were recommended: There should be the provision of gainful employment through the setting up of industries, factories and other establishments. This employment should be made to incorporate both educated and uneducated people based on merit and according to their area of competence; Skill’s Acquisition Centers should be widely set up so that those who cannot cope can learn trades that would help them to face life’s challenges, etc. Keywords: Hunger, Food, Vices, Armed-Robbery, Prostitution, Pick-Pocketing, Over- Profiteering, Poverty, Begging, Nuisanc

Orange-fleshed Sweetpotato on the home grownschool feeding menu in Nigeria

Sweetpotato for health and wealth in Nigeria and Jumpstarting OFSP in West Africa for diversified markets are two projects that focus on development of the value chain for health and wealth of the rural households in Nigeria, working in Osun and Kwara states. Out of search for OFSP demand at the formal sector, inclusion in the school feeding menu was conceived. The flyer presents the stages of inception, advocacy and sensitization that resulted in the inclusion of OFSP in the School Feeding Program in Osun State, as well as the achievements made between June 2014 and July 2015, and plans for scaling up

Mother-Tongue Based (MTB) Schooling: A Key for Transforming Early Childhood Education for Future Generation in Nigeria

The study sought to determine the extent of usage of Igbo Language as a medium of instruction and interaction in the lower basic classes in Enugu North Education Zone, Enugu State, Nigeria. Four research questions guided the study. The design was a descriptive survey. The population consisted of 2069 teachers (198 Head teachers and 1,871 Classroom teachers) in Enugu North Education zone of Enugu state, public and private schools inclusive. The sample was 200 teachers (50 Head teachers and 150 Class teachers) drawn from the population using stratified random sampling technique. The instrument used for data collection was researchers developed questionnaire titled “Mother-Tongue Based Schooling Questionnaire” (MTBSQ) which was face validated by experts in Igbo Language and Measurement and Evaluation from Federal College of Education, Kotangora, Niger State. The reliability estimate of MTBSQ established using Pearson’s co-efficient formula was 0.86.  Findings indicated very low extent of the use of mother tongue (Igbo Language) as a medium of instruction and interaction; schools and parents preferred the use of English Language (L2) as a medium of instruction and interaction; and indigenous materials and textbooks in mother tongue were not available or used for instruction. By educational implication, this is a negation of the National policy stipulation on the usage of mother-tongue for instruction in Nigerian schools.  The researchers therefore recommended that Government should lay emphasis on total implementation of the National Policy on Education with particular reference to usage of mother-tongue as a medium of instruction in pre-primary and primary schools in Nigeria. Also, parents and care-givers should be educated on the need for them to interact with children in their mother-tongue. Keywords: early childhood education, future generation, mother tongue.

The Contribution of Nigeria Health Sector Recurrent Spending on Its Output (1961-2012)

Health sector in any country has been recognized as the primary engine of growth and development. This study makes a modest contribution to the debates by empirically analyzing the contribution of Nigeria Health sector recurrent spending on its output using time series data from 1961 to 2012, obtained from the Central Bank of Nigeria. It employs the Ordinary Least Square (OLS) regression technique and Pair wise Granger Causality tests. The estimation reviews that Political Stability (PSB) and Consumer Price Index (CPI) in Nigeria have positive effect on Total health output (HGDP) while Total Government Recurrent Expenditure on Health (TGREH) has a negative effect on Total health output (HGDP). On the contrary, rising Government recurrent expenditure on health does not results to an increase in Total health output. Based on the result of granger causality, the paper concludes that a very weak causality exist between the two main variables used in this study. The authors therefore advised that there should be a reduction in government recurrent expenditure in the health sector. Also there should be a high degree of transparency and accountability in government spending
