Including the Excluded: The Case of Slow Learners at Buloba Primary School, Uganda

This article describes a study of Mathematics teachers at Buloba Primary School in Uganda. The purpose was to analyse the teachers’ perceptions, essential practices for creating inclusive classroom environments for slow learners, and implementation challenges. This quasi-experimental research included a focus group discussion, an interview with the headteacher, three lesson observations and post-observation focus group discussions. The results indicate that the teachers have mixed perceptions and several practices: peer learning, certain teaching methods, linking teaching to real-world applications, seating environment, and providing a threat -free classroom environment. Highlighted challenges include heavy workloads, limited time, inadequate training, mixed classes of both slow and fast learners, inability to identify slow learners, class size and lack of knowledge. It emphasizes the need to define and develop reference frameworks of teacher competencies and institutionalize in-service teacher education programmes through school-based practices and research.Group C: Teacher Professional Developmen

High performance computation of landscape genomic models integrating local indices of spatial association

Since its introduction, landscape genomics has developed quickly with the increasing availability of both molecular and topo-climatic data. The current challenges of the field mainly involve processing large numbers of models and disentangling selection from demography. Several methods address the latter, either by estimating a neutral model from population structure or by inferring simultaneously environmental and demographic effects. Here we present Sam$\beta$ada, an integrated approach to study signatures of local adaptation, providing rapid processing of whole genome data and enabling assessment of spatial association using molecular markers. Specifically, candidate loci to adaptation are identified by automatically assessing genome-environment associations. In complement, measuring the Local Indicators of Spatial Association (LISA) for these candidate loci allows to detect whether similar genotypes tend to gather in space, which constitutes a useful indication of the possible kinship relationship between individuals. In this paper, we also analyze SNP data from Ugandan cattle to detect signatures of local adaptation with Sam$\beta$ada, BayEnv, LFMM and an outlier method (FDIST approach in Arlequin) and compare their results. Sam$\beta$ada is an open source software for Windows, Linux and MacOS X available at \url{http://lasig.epfl.ch/sambada}Comment: 1 figure in text, 1 figure in supplementary material The structure of the article was modified and some explanations were updated.

Molecular characterization of serotype O foot-andmouth disease virus from pigs: Implications for multispecies approach to disease control in Uganda

In Uganda, where foot-and-mouth disease (FMD) control is mainly done through vaccination, constant monitoring of outbreaks and phylogenetic studies are important in designing effective disease control strategies. These efforts however, have mainly concentrated on cattle since they are the main visible disease hosts. In this study, the molecular characteristics of the VP1 coding sequences of the pigderived FMD virus and its phylogenetic relationship with other historical Ugandan FMD virus sequences are determined. Sixty seven samples were collected from three districts of south western Uganda and subjected to RT-PCR. Partial VP1 capsid protein coding sequences of 12 positive samples were amplified and sequenced using serotype specific primers. Eight sequences were successfully obtained, all of which were from domestic pigs. All samples were confirmed as belonging to serotype O using BLAST search. Phylogenetic analysis of the test sequences with selected sequences, showed a close relatedness (average of 3.77% pair-wise distance) to viruses isolated from central and western Uganda in the years 2005 and 2006 from cattle. These results show that domestic pigs in the western region of Uganda have been infected with the same circulating strain of FMDV and play a potentially important role in FMD maintenance and spread.Keywords: Foot-and-mouth disease (FMD), pig-derived FMDV sequence, persistence, domestic pigsAfrican Journal of Biotechnology Vol. 12(19), pp. 2547-255

One hundred years of African swine fever : a tribute to R. Eustace Montgomery

One hundred years ago, the first scientific publication on “a form of swine fever” that occurred in East Africa was published by R. Eustace Montgomery in the Journal of Comparative Pathology and Therapeutics (Montgomery, 1921). Now known as African swine fever (ASF), this disease has, over the last century, been reported from all five continents and is dreaded by pig industries worldwide (Liang et al., 2020; Penrith, 2020 ). It is hoped that this tribute will contribute to ensuring that the great legacy of Montgomery's research is not forgotten.https://wileyonlinelibrary.com/journal/tbedhj2022Veterinary Tropical Disease

Genome sequences of five African swine fever virus genotype IX isolates from domestic pigs in Uganda

Complete genome sequences of five African swine fever virus isolates were determined directly from clinical material obtained from domestic pigs in Uganda. Four sequences were essentially identical to each other, and all were closely related to the only known genome sequence of p72 genotype IX

Wild and Domestic Pig Interactions at the Wildlife–Livestock Interface of Murchison Falls National Park, Uganda, and the Potential Association with African Swine Fever Outbreaks

Bushpigs (BPs) (Potamochoerus larvatus) and warthogs (WHs) (Phacochoerus africanus), which are widely distributed in Eastern Africa, are likely to cohabitate in the same environment with domestic pigs (DPs), facilitating the transmission of shared pathogens. However, potential interactions between BP, WH, and DP, and the resulting potential circulation of infectious diseases have rarely been investigated in Africa to date. In order to understand the dynamics of such interactions and the potential influence of human behavior and husbandry practices on them, individual interviews (n = 233) and participatory rural appraisals (n = 11) were carried out among Ugandan pig farmers at the edge of Murchison Falls National Park, northern Uganda. In addition, as an example of possible implications of wild and DP interactions, non-linear multivariate analysis (multiple correspondence analyses) was used to investigate the potential association between the aforementioned factors (interactions and human behavior and practices) and farmer reported African swine fever (ASF) outbreaks. No direct interactions between wild pigs (WPs) and DP were reported in our study area. However, indirect interactions were described by 83 (35.6%) of the participants and were identified to be more common at water sources during the dry season. Equally, eight (3.4%) farmers declared exposing their DP to raw hunting leftovers of WPs. The exploratory analysis performed suggested possible associations between the farmer reported ASF outbreaks and indirect interactions, free-range housing systems, dry season, and having a WH burrow less than 3 km from the household. Our study was useful to gather local knowledge and to identify knowledge gaps about potential interactions between wild and DP in this area. This information could be useful to facilitate the design of future observational studies to better understand the potential transmission of pathogens between wild and DPs. (Résumé d'auteur
