Influence of Subject Area and Level of Academic Achievement on University Studentsâ Propensity for Academic Dishonesty
Academic dishonesty is a persistent problem in higher education and it threatens the integrity and legitimacy of university education. This study examined the influence of undergraduate studentsâ subject area and level of academic achievement on propensity for academic dishonesty. It also examined the interaction effect between subject specialization and level of academic achievement on academic dishonesty while controlling for age. Participants were 425 Bachelor of Education students from seven public universities in Kenya. Students taking a Bachelor of Education Science had a significantly higher academic dishonesty mean score compared to students taking a Bachelor of Education Arts. There were no significant differences in participantsâ academic dishonesty mean scores by level of academic achievement. There were also no significant interactions between subject area and level of academic achievement on academic dishonesty, whilst controlling for age. The study concluded that students taking a Bachelor of Education Science course were more likely to engage in academic dishonesty compared to students taking a Bachelor of Education Arts. Implications for the findings are discussed in depth. Keywords: Academic achievement, academic dishonesty, subject area DOI: 10.7176/JEP/13-21-07 Publication date:June 30th 202
Hepatoprotective activity of aqueous extract of Balanites aegyptiaca L. Delile (Balanitaceae) roots bark
Balanites aegyptiaca (L.) Del (Balanitaceae) is traditionally used for the treatment of various ailments such as syphilis, jaundice and liver disorders, epilepsy, ... This study was designed to evaluate acute toxicity and hepatoprotective effect of aqueous extract of Balanites aegyptiaca on CCl4 induced hepatotoxicity in rats.Methods: Acute toxicity was assessed with the extract at a dose of 2000 mg / kg bw. The extract at doses of 25, 50 and 100 mg / kg b.w. was orally administered respectively to CC14-induced hepatotoxicity (0.5 ml / kg) animals. Silymarin (100 mg / kg) was given as a reference. Biochemical parameters such as ALT, AST, PT, ALB and ALP were assayed as well as enzymatic antioxidant activities SOD, CAT and MDA. Nitrogen monoxide (NO) involved in inflammation was also measured.Results: Activities of liver marker enzymes, ALT, AST and ALP, total protein, albumin and showed a significant hepatoprotective effect. Regarding antioxidant enzymatic activities in vivo (SOD, CAT and MDA) of aqueous extract exhibited a significant effect showing increasing levels of SOD, CAT and reducing malondialdehyde (MDA) levels. The production of NO is significantly reduced compared to the batch intoxicated by CCl4.Conclusion: Balanites aegyptiaca is endowed with hepatoprotective properties that can be attributed to antioxidant potential which could justify its use in traditional medicine in liver disorders
Effect of artemether-lumefantrine policy and improved vector control on malaria burden in KwaZulu-Natal, South Africa
Between 1995 and 2000, KwaZuluâNatal province, South Africa, experienced a marked increase in Plasmodium falciparum malaria, fuelled by pyrethroid and sulfadoxine-pyrimethamine resistance. In response, vector control was strengthened and artemether-lumefantrine (AL) was deployed in the first Ministry of Health artemisinin-based combination treatment policy in Africa. In South Africa, effective vector and parasite control had historically ensured low-intensity malaria transmission. Malaria is diagnosed definitively and treatment is provided free of charge in reasonably accessible public-sector health-care facilities
Effect of Artemether-Lumefantrine Policy and Improved Vector Control on Malaria Burden in KwaZuluâNatal, South Africa
BACKGROUND: Between 1995 and 2000, KwaZuluâNatal province, South Africa, experienced a marked increase in Plasmodium falciparum malaria, fuelled by pyrethroid and sulfadoxine-pyrimethamine resistance. In response, vector control was strengthened and artemether-lumefantrine (AL) was deployed in the first Ministry of Health artemisinin-based combination treatment policy in Africa. In South Africa, effective vector and parasite control had historically ensured low-intensity malaria transmission. Malaria is diagnosed definitively and treatment is provided free of charge in reasonably accessible public-sector health-care facilities. METHODS AND FINDINGS: We reviewed four years of malaria morbidity and mortality data at four sentinel health-care facilities within KwaZuluâNatal's malaria-endemic area. In the year following improved vector control and implementation of AL treatment, malaria-related admissions and deaths both declined by 89%, and outpatient visits decreased by 85% at the sentinel facilities. By 2003, malaria-related outpatient cases and admissions had fallen by 99%, and malaria-related deaths had decreased by 97%. There was a concomitant marked and sustained decline in notified malaria throughout the province. No serious adverse events were associated causally with AL treatment in an active sentinel pharmacovigilance survey. In a prospective study with 42 d follow up, AL cured 97/98 (99%) and prevented gametocyte developing in all patients. Consistent with the findings of focus group discussions, a household survey found self-reported adherence to the six-dose AL regimen was 96%. CONCLUSION: Together with concurrent strengthening of vector control measures, the antimalarial treatment policy change to AL in KwaZuluâNatal contributed to a marked and sustained decrease in malaria cases, admissions, and deaths, by greatly improving clinical and parasitological cure rates and reducing gametocyte carriage
Comparison of the capture efficiency of a killâtrap set for brushtail possums that excludes groundâbirds, and ground set legâhold traps
Seven years of regional malaria control collaboration--Mozambique, South Africa, and Swaziland.
The Lubombo Spatial Development Initiative is a joint development program between the governments of Mozambique, Swaziland, and South Africa, which includes malaria control as a core component of the initiative. Vector control through indoor residual spraying (IRS) was incrementally introduced in southern Mozambique between November 2000 and February 2004. Surveillance to monitor its impact was conducted by annual cross-sectional surveys to assess the prevalence of Plasmodium falciparum infection, entomologic monitoring, and malaria case notification in neighboring South Africa and Swaziland. In southern Mozambique, there was a significant reduction in P. falciparum prevalence after the implementation of IRS, with an overall relative risk of 0.74 for each intervention year (P < 0.001), ranging from 0.66 after the first year to 0.93 after the fifth intervention year. Substantial reductions in notified malaria cases were reported in South Africa and Swaziland over the same period. The success of the program in reducing malaria transmission throughout the target area provides a strong argument for investment in regional malaria control
Assessment of the impact of the rise in Lake Victoria water levels on urban flooding using a GIS-based spatial flood modelling approach
During the period 2018â2021, Lake Victoria experienced a rapid rise in water levels that caused significant urban flooding consequences. However, there are no studies that have extensively investigated the effect of the rising lake water levels on urban flooding. This research responds to this by developing and applying a GIS-based spatial flood modelling approach to simulate the resulting flooding impacts in Entebbe City, Uganda, corresponding to the May 2021 observed maximum lake water level of 13.49âm. Using the validated GIS-based flood model, the simulated flooded area and average flood depth were determined as 9.1âkm2 and 1.52âm, respectively. Furthermore, through application of GIS overlay analysis, the total number of affected buildings and length of urban roads were quantified. The proposed methodology provides a robust and computationally efficient approach for identification of at-risk buildings along the lake shoreline and for testing the effectiveness of potential adaptation strategies.</p
