    BACKGROUND: In October 2009, the first case of pandemic influenza A(H1N1)pdm09 (pH1N1) was confirmed in Kigali, Rwanda and countrywide dissemination occurred within several weeks. We describe clinical and epidemiological characteristics of this epidemic. METHODS: From October 2009 through May 2010, we undertook epidemiologic investigations and response to pH1N1. Respiratory specimens were collected from all patients meeting the WHO case definition for pH1N1, which were tested using CDC's real time RT-PCR protocol at the Rwandan National Reference Laboratory (NRL). Following documented viral transmission in the community, testing focused on clinically severe and high-risk group suspect cases. RESULTS: From October 9, 2009 through May 31, 2010, NRL tested 2,045 specimens. In total, 26% (n = 532) of specimens tested influenza positive; of these 96% (n = 510) were influenza A and 4% (n = 22) were influenza B. Of cases testing influenza A positive, 96.8% (n = 494), 3% (n = 15), and 0.2% (n = 1) were A(H1N1)pdm09, Seasonal A(H3) and Seasonal A(non-subtyped), respectively. Among laboratory-confirmed cases, 263 (53.2%) were children <15 years and 275 (52%) were female. In total, 58 (12%) cases were hospitalized with mean duration of hospitalization of 5 days (Range: 2-15 days). All cases recovered and there were no deaths. Overall, 339 (68%) confirmed cases received oseltamivir in any setting. Among all positive cases, 26.9% (143/532) were among groups known to be at high risk of influenza-associated complications, including age <5 years 23% (122/532), asthma 0.8% (4/532), cardiac disease 1.5% (8/532), pregnancy 0.6% (3/532), diabetes mellitus 0.4% (2/532), and chronic malnutrition 0.8% (4/532). CONCLUSIONS: Rwanda experienced a PH1N1 outbreak which was epidemiologically similar to PH1N1 outbreaks in the region. Unlike seasonal influenza, children <15 years were the most affected by pH1N1. Lessons learned from the outbreak response included the need to strengthen integrated disease surveillance, develop laboratory contingency plans, and evaluate the influenza sentinel surveillance system

    The overarching aim of this thesis is to explore how teaching and learning in tertiary education is performed in times of change both in language policy and learning approaches. The study takes social constructivist and socio-cultural theories as its major points of departure. These theories are combined with cognitive theory of learning with multimedia. The four studies comprising this thesis are born out of a new situation demanding the mastery of a scientific language in English and new ways of teaching and learning backed with ICT. The studies set out to investigate (i) how students and teachers adapt to a change of medium of instruction (ii) what teachers and students of physics learn when constructing a multimedia vocabulary learning instrument (iii) the impact of two methods of teaching vocabulary on students’ test performance and (iv) how teachers reflect on the use of ICT in Physics teaching. To attain these targets, the study employed a blend of qualitative and quantitative designs to gather relevant data. In three studies, data were gathered from classroom practices in tertiary education. The fourth study included teacher interviews on their experiences with ICT. Findings indicate that the understanding of physics was facilitated by a variation in language use in different classroom spaces, students and teachers’ collaborative selection of technical vocabulary and a multimedia tool of technical vocabulary software constructed by two teachers and the researcher. According to the teachers, the quality of physics teaching would be enhanced further by adopting learner-centred teaching methods and the integration of more advanced ICT. The studies show that teachers and students are on their way to develop ICT tools for teaching and learning. Given adequate support, this can pave the way for transforming teaching and allowing for further quality development in innovative and creative ways of learning with ICT.Det övergripande syftet med denna avhandling Ă€r att undersöka hur undervisning och lĂ€rande inom högre utbildning sker i tider av förĂ€ndring bĂ„de inom sprĂ„kpolicy och inom lĂ€rande. Studien tar socialkonstruktivistiska och socio-kulturella teorier som utgĂ„ngspunkt. Dessa teorier har kombinerats med en kognitiv teori om lĂ€rande med multimedia. Studien bestĂ„r av fyra studier som behandlar den nya situation som uppstĂ„tt nĂ€r studenter och lĂ€rare behöver bemĂ€stra ett vetenskapligt sprĂ„k pĂ„ engelska och nya sĂ€tt att undervisa och lĂ€ra med stöd av IKT. Studiernas syfte Ă€r att undersöka (i) hur studenter och lĂ€rare anpassar sig till ett förĂ€ndrat undervisningssprĂ„k (ii) vad lĂ€rare och studenter inom fysik lĂ€r nĂ€r de konstruerar ett multimedia instrument (iii) utfallet av tvĂ„ olika metoder att lĂ€ra studenter ett facksprĂ„k inom fysik som det visar sig i olika test (iv) hur lĂ€rare reflekterar över anvĂ€ndningen av IKT inom Ă€mnesomrĂ„det fysik. För att uppnĂ„ dessa mĂ„l anvĂ€nds en kombination av kvalitativa och kvantitativa metoder. I tre studier samlades data frĂ„n klassrumspraktiker inom högre utbildning. I den fjĂ€rde studien intervjuades lĂ€rare om sina erfarenheter med IKT. Resultaten visar att förstĂ„else av facksprĂ„kliga begrepp underlĂ€ttades av att olika sprĂ„k anvĂ€ndes beroende pĂ„ avstĂ„nd eller nĂ€rhet till eleverna i klassrummet. Samarbete mellan studenter och lĂ€rare i att vĂ€lja ord och begrepp som skulle anvĂ€ndas och mellan lĂ€rarna och forskaren i att konstruera ett multimedia-instrument pĂ„verkade ocksĂ„ lĂ€randet positivt. Enligt de intervjuade lĂ€rarna skulle kvaliteten i fysikundervisningen kunna förbĂ€ttras ytterligare genom att anvĂ€nda elevcentrerade undervisningsmetoder och mer avancerad IKT. Studierna visar att lĂ€rare och studenter Ă€r pĂ„ vĂ€g att utveckla IKT redskap för undervisning och lĂ€rande. Med adekvat stöd kan detta bereda vĂ€gen för en transformering av undervisningen och ge utrymme för vidare kvalitetsutveckling genom uppfinningsrika och kreativa sĂ€tt att lĂ€ra med stöd av IKT

    This case study examines how a lecturer and a group of students adjust to a request for English-only medium of instruction in tertiary education. The study draws on sociocultural theories considering context and language use as tools for meaning making. Goffman's theories of stage setting and footing are used to analyse how the lecturer positions himself in relation to language use. The findings show that in the observed session the lecturer used code-switching as a tool to extend students’ academic literacy. Further, we found that he in most cases assigned different classroom spaces to different languages. Hence, English as the targeted language of instruction was used when the lecturer was standing at the board, the official teaching space, whereas French, a previously accepted language, was used in a semi-official space closer to the students. Kinyarwanda, the lecturer's and students’ first language, is not permitted as a medium of instruction, but was used when the lecturer was close to the students. We label this a personal space, where the lecturer changed code in order to improve interaction and students’ understanding. Such code-switching has cultural and historical traditions and is viewed in this study as a strategy to avoid misunderstandings and allow more equitable learning opportunities.Projektet har stöd av Sida/SARECNUR-LiU PhD-programme in Educatio
