Educators’ disciplinary capabilities after the banning of corporal punishment in South African schools
C Maphosa, A Shumba
South African Journal of Education , 2010,
Abstract: The escalation of learner indiscipline cases in schools suggests failure by teachers to institute adequate alternative disciplinary measures after corporal punishment was outlawed in South African schools. We sought to address the following two research questions: (a) How do educators view their disciplinary capabilities in the post-corporal punishment period? and (b) How do educators view the usefulness of alternative disciplinary measures? The study adopted a qualitative approach. A case study of three purposively selected practising junior secondary school educators was used. Data were collected through interviews. We found that educators generally feel disempowered in their ability to institute discipline in schools in the absence of corporal punishment. Educators revealed that learners do not fear or respect educators because they know that nothing will happen to them. Although educators are aware of alternative disciplinary measures, they view them as ineffective and time consuming.

Onderstepoort Journal of Veterinary Research , 2010, DOI: 10.4102/ojvr.v76i2.50
Abstract: Rapid immunodiagnostic test kit was evaluated against a selection of isolates of lyssavirus genotypes occurring in Africa. The test was carried out in parallel comparison with the fluorescent antibody test (FAT) and isolates representing previously established phylogenetic groups from each genotype were included. The specificity of the rapid immunodiagnostic test compared favourably with the FAT and was found to detect all representatives of genotypes 1, 2, 3 and 4 in brain samples of either field cases or suckling mouse brain inoculates.

ISRN AIDS , 2013, DOI: 10.1155/2013/270914
Abstract: Background. Missed doses and appointments are predictors of incomplete adherence among patients on ART. The AIDSRelief model emphasizes treatment preparation and continuous treatment support for ART patients including community followup. Methods. In August 2008, a survey was conducted among patients on antiretroviral therapy (ART) (interquartile range for duration of ART?=?29–46 months, median?=?33 months, , age >16 years), in 15 health facilities in Uganda. Missed doses and appointments among adult patients on ART and the factors most associated with these were identified. Reasons for missed doses were also explored. Results. The survey revealed that 97% of the patients had not missed their doses in the last week while 93% had not missed their appointments in the last three months. For those who had missed their doses, the most common reasons were travel (48%) and forgetfulness (28%). There was a significant association between missing doses and missing appointments ( ) and between alcohol use and missed doses ( ). Conclusions. The level of adherence to medication and clinic appointments for patients on ART in the study population was very high. It is important to strengthen adherence strategies at both facility and community levels to assist patients that are likely to miss their doses or appointments. 1. Background Uganda has more than 1.2 million people living with HIV infection and in 2010 more than 120,000 got infected with HIV [1]. Although there are various efforts to scale up AIDS treatment, many HIV-infected people are unable to access treatment and the increasing new HIV infections still exceed the government’s capacity to provide treatment [2]. While attempts are being made to reduce new infections and to scale up antiretroviral therapy (ART), it is equally important to improve adherence to regimens among the few who are already accessing ART for successful treatment [3]. ART delays progression to AIDS and death, hence, improved the quality of life for people living with HIV [4, 5]. Maintaining good adherence has been found to be difficult to achieve and sustained by both patients and health care providers [6, 7]. A major concern with the use of ART is the emergence of viral resistance, which is mainly due to insufficient compliance [8]. Different tools have been used to determine ART adherence rates and on average the rate of adherence to ART is about 70% [9]. A meta-analysis found adherence rates for African patients to be approximately 77% [10]. A study by Oyugi et al., that assessed correspondence between multiple measures of adherence

Bulletin of the World Health Organization , 2002, DOI: 10.1590/S0042-96862002000300006
Abstract: objective: to determine the age-weighting preferences of urban zimbabweans in relation to health care priorities. method: a total of 67 randomly selected residents of a high-density area of harare participated in the study. participants were asked "person trade-off" questions to determine their preferences in terms of the numbers of people of various ages who would be saved from death and from suffering a year of ill-health relative to the number of 30-year-olds who would be saved from these eventualities. findings: the responses indicate that the value of averting a year of ill-health was judged greatest for 15-year-olds and was equal for people aged 1, 30, and 45 years. the value of averting a death primarily reflected the expected years of life lost, but the influence of age-weighting was evident in that 15 years was the most highly valued age. conclusion: although the age-weighting curves did not correspond exactly with the global burden of disease (gbd) age-weights, zimbabweans showed a preference for saving the lives of young adults. the gbd age-weights should be used to determine the disability-adjusted life years lost in the zimbabwean population.
Behavioral Characteristics of Adult Patients on Highly Active Antiretroviral Therapy (HAART) in Uganda

Global Journal of Medicine and Public Health , 2012,
Abstract: Background: Behavioral factors have an impact on patient adherence and treatment outcomes. Specific information on behavioral factors is however minimal at health facilities in resource settings. Such information is vital in helping health facilities to provide targeted interventions. Method: Adherence surveys (n=783) were carried out to assess self-reported condom use, alcohol intake in the past month and disclosure in patients 19 years and above on HAART in 19 HIV clinics. Health workers were trained on how to administer the survey questions. The questions aimed at determining risky behaviors and disclosure of HIV illness. Results: More than half of the patients (59%) do not use condoms in the 19 HIV clinics. 30% reported using condoms always. Most of the patients (79%) on HAART had not taken alcohol in the past one month suggesting that most patients on HAART did not use alcohol. The majority of the patients (99%) disclosed their status with implications for better adherence and increased psychosocial support. Conclusion: It may be important to relate condom use, alcohol intake and disclosure to viral suppression and also advocate for comprehensive positive prevention at the HIV clinics. There is need to carry out an in-depth analysis of alcohol intake among HAART patients. Steps should be taken to address these behavioral issues in support groups and community programs

Abstract: Розглянуто вплив випаровуваност альтернативних палив на р шення проблеми холодного пуску двигуна за рахунок використання пропан-бутаново сум ш для п двищення тиску насичено пари. Volatility fuels fraction of the estimated parameters and letkosti. Volatility characterizes the ability to switch fuels in vaporous state. Selecting indicators to assess the volatility depends on the chemical composition of fuel. The main measure letkosti etanolnogo fuel is vapor pressure. The most simple and cost-effective to improve cold start is putting in fuel lehkoletyuchyh components: butane, izopentanu, gas and other petroleum. It was investigated the influence of DEE on alcohol-gasoline blend, the results show that DEE positive impact on increasing vapor pressure to the desired minimum for starting the engine. But because the ether to 19%, then at such high levels can actively formed peroxide compounds, which is undesirable. Very promising is the use of propane-butane gas mixture as lehkoletyuchoyi gaseous component. Butanizovani spirit-petrol mixture can be recommended for use as alternative fuel vehicles after further study of their stability and himmotolohichnyh characteristics. Автомобильные бензины и альтернативные биологические топлива на основе этанола преимущественно предназначены для применения в двигателях внутреннего сгорания. При использовании альтернативного биологического топлива, особенно этанольного, возникает проблема недостаточной испаряемости бензина при низкой температуре, в результате чего в холодное время года двигатель может не запуститься. Пусковые свойства бензина зависят от содержания в них летучих фракций или летучих соединений. Проблему холодного запуска предлагается решать за счет использования пропан-бутановой смеси для повышения давления насыщенного пара. Для перспективного применения газов пропан-бутановой смеси легколетучего газообразного компонента необходимы дальнейшие исследования стабилизации такой композиции.
