    Matematikens roll i fysiken på gymnasiet2019Other (Other (popular science, discussion, etc.))
    Abstract [sv]

    Syftet med vårt projekt är att fördjupa förståelsen av matematikens roll i fysikundervisningen. I fysiken är matematiken ett viktigt verktyg – man pratar om matematiken som fysikens språk. Samtidigt upplevs matematik som ett hinder för meningsfullt lärande i fysik. Elever kan bli så upptagna av matematiska operationer att fysikaliska modellers innebörd och relation till de verkliga fenomen de beskriver hamnar i bakgrunden. Vi har studerat hur relationer mellan verklighet, teoretiska modeller och matematik kommuniceras i olika undervisningssituationer i svensk gymnasiefysik. Resultaten visar på samband mellan fysiklärares syn på syftet med fysikundervisningen och matematikens roll i deras klassrum.

    Reality – theoretical models – mathematics in physics teaching2019Conference paper (Refereed)
    Abstract [en]

    Science teaching and particularly chemistry and physics teaching is subject to ongoing discussions concerning aims, goals and relation to modern society, as well as how to teach so that more students find physics interesting and meaningful. The need for further research on reasons why physics teaching is diverse and teaching shows different curriculum emphases have been put forward by several authors (cf. Belo, van Driel, van Veen, & Verloop, 2014; Johansson, Andersson, Salminen-Karlsson, & Elmgren, 2016). The general picture is that relationships between teachers views, curriculum emphases, classroom practices, problems and possible student shortcomings need further studies in order to generate more knowledge about the basis for teaching conditions helping students to gain knowledge and interest in physics.This study continues a line of research that has a special focus on the role of mathematics in physics teaching (cf. Redfors, 2015; 2018; Turşucu, Spandaw, Flipse, & de Vries, 2017). One strand of this research focus on students’ problems in transferring mathematical knowledge to new and applied situations during physics teaching (cf. Kuo, Hull, Gupta, & Elby, 2013). However, there is also research focusing not only problem-solving, but physics teaching in general, from the perspective of the role of mathematics skills among students, since this is viewed as important for physics learning (Angell, Lie, & Rohatgi, 2011; Uhden, Karam, Pietrocola, & Pospiech 2012; Redfors, 2015; 2018). The aim of this three-year study is to further contribute to the understanding of how relations between Reality – Theoretical models – Mathematics are communicated in different kinds of instructional situations (lectures, problem solving and labwork) in Swedish upper-secondary physics. A developed analytical framework from the pilot (Redfors 2015; 2019) is used to focus the analysis of the classroom communication on relations made (by teachers and students) between Reality – Theoretical models – Mathematics. The framework, results from an online survey to Swedish upper-secondary teachers on views of physics, mathematics and physics teaching, and results from classroom studies at upper secondary school during 2018-2019 will be reported and discussed at the conference.

    The role of mathematics in the teaching and learning of physics2014In: Ebook proceedings of the ESERA 2013 conference, Nicosia, Cyprus: European Science Education Research Association , 2014, Part 2, p. 376-383Conference paper (Refereed)
    Abstract [en]

    This paper discusses the role of mathematics in physics teaching andlearning. The intention and strength of science is to describe what happens in the realworld by organizing explanations through theories and theoretical models. It has beenwidely suggested that learning in science is influenced by views about the nature ofscientific knowledge. Furthermore, mathematics is an inherent part of theories andmakes powerful predictions of natural phenomena possible. Ability to use mathematicsto argue and prove results is central in physics. Students have been found tostruggle with physics problems where they need to relate mathematically formulatedtheoretical models to the real world. This project has explored the role of mathematicsfor physics teaching and learning in upper-secondary school through investigations ofrelations made during physics lessons (lectures, problem solving and lab-work)between The real world – Theoretical models – Mathematics. A preliminary analysisindicate that there are some connections made by students and teacher betweentheories and the real world, but the bulk of the discussion in the classroom is concerningthe relation between theoretical models and mathematics, which is in linewith earlier research on problem solving. The preliminary results reported on hereindicate that this also holds true for all the investigated organisational forms lectures,problem solving in groups and lab-work. A finalized and extended analysis will bepublished elsewhere.

    Socio-scientific collaborative inquiry in astrobiology: the design and implementation of a digital learning environment2010In: Contemporary science education research: teaching / [ed] M. F. Taşar & G. Çakmakci, 2010, p. 231-241Conference paper (Refereed)
    Abstract [en]

    In a European project – CoReflect – researchers in seven countries are developing, implementing and evaluating teaching sequences using a web-based platform (STOCHASMOS). The interactive web-based inquiry materials support collaborative and reflective work. The project methodology is based on the idea of design-based research, which seeks to bridge the often disconnected worlds of academia and educational practices. Hence, the teachers are engaged throughout the project. The learning environments will be iteratively tested and refined, first as pilot projects, then during local implementations, and finally during implementations and synthesis work at the European level. All learning environments are focusing “socio-scientific” issues.  In this article we report from the pilot of the Swedish learning environment with an Astrobiology context. The socio-scientific driving questions were “Should we look for, and try to contact, extraterrestrial life?”, and “Should we transform Mars into a planet where humans can live in the future?” The students are in their last year of compulsory school (16 years old), and worked together in triads. We report from the groups’ decisions and arguments used. A majority of the groups express reluctance towards both the search of extraterrestrial life and the terraforming of Mars.

    Teaching astrobiology from a socio-scientific perspective using a digital learning environment2010Conference paper (Refereed)
    Abstract [en]

    We report from the European project CoReflect (www.coreflect.org) where groups in Cyprus, England, Germany, Greece, Israel, Sweden and the Netherlands are developing, implementing and evaluating teaching sequences using the internet platform Stochasmos (Kyza & Constantinou, 2007). Within this design-based project (Barab & Squire, 2004) teach­ers and researchers work together on the design of digi­tal learning environ­ments (LE:s). The approach seeks to bridge the worlds of academia and the world of educational practice. All LE:s build on dif­ferent socio-scientific issues (Sadler, 2004), and Stochasmos are used to help teachers scaf­fold students in collaborative learning.

    The local working groups of researchers and teachers design one LE each. The design goes through different phases: implementation, review and refinement. The aim of this article is to describe these phases, for the Swedish LE. The Swedish group chose socio-scientific issues in the content area of Astrobiology. Astrobiology captures questions that have been found to be of interest to students (Sjøberg & Schreiner, 2006). The socio-scientific driving questions are:

    Should we look for, and try to contact, extraterrestrial life?

    Should we transform Mars into a planet where humans can live in the future?

    Students are expected to: a) demonstrate a basic understanding of essential concepts of astrobiology, b) discuss the nature of science, c) link hands-on lab-work to astrobiology research, d) provide evidence-based answers to the driving questions, using scientific, social, economical and ethical perspectives.

    Based on the evaluation of the pilot enactment several changes were made in Stochasmos and to the teachers’ guide. Even though Stochasmos gives the work structure, through tabs and templates the need for a scaffolding teacher was obvious. The teacher needs to be familiar and knowledgeable about the content in order to be able to produce challenging questions. A stricter planning for the teacher, with explicit instruction about student activities was introduced to promote science oriented discussions. The students liked working with the computer – it is a familiar environment. The teacher experienced an increase in student anticipation and focus. The analysis of the second enactment is ongoing, and will be presented at the conference.

    Web-based Collaborative Teaching of Astrobiology in the EU-project – CoReflect2010Conference paper (Refereed)
    Abstract [en]

    Groups in Cyprus, Israel, Germany, The Netherlands, Greece, England and Sweden have developed, implemented and evaluated teaching sequences using the web-based platform STOCHASMOS in a EU-project – www.coreflect.org. The interactive web-based inquiry materials support collaborative and reflective work. The sequences have been tested as pilot projects and revised for a second local implementation. They will be culturally adopted for a third enactment in a partner country.

     

    The Swedish learning environment is Astrobiology for secondary students (9th grade, 16 years). Scientific, social, economical and ethical perspectives are taken on the driving question: Should we look for, and try to contact, extraterrestrial life?

     

    Empirical data from the final enactment, including students’ worldviews and their use of scientific arguments, will be discussed at the conference. Preliminary results from the pilot show that students appreciate the teaching, and we see an increase in students’ motivation.

    Student teachers’ use of models of matter: a progress report2005Conference paper (Other academic)
    Abstract [en]

    Empirical data on student teachers' use and views of models in physics are investigated. Students’ explanations of phenomena are analysed with the link between model/theory and reality in focus. A secondary focus is how the students’ use of explanatory models is influenced by their views about the nature of scientific knowledge. The project has a combined cross sectional and longitudinal design. Written questionnaires are used, in combination with follow up interviews. Three different phenomena are discussed, a burning candle, a gas flame and a flask with air confined by a balloon. Data is analysed with respect to a theoretical model of learning assuming that students use several different explanatory models, and that they use more than one in explanations of everyday phenomena. Results from this exploratory study are planned to guide further research on how teaching can build upon different perspectives of models to improve student learning.

    The Fe II excitation mechanism in KQ Puppis2000In: Astronomy and Astrophysics, ISSN 0004-6361, E-ISSN 1432-0746, Vol. 364, no 2, p. 646-654Article in journal (Refereed)
    Abstract [en]

    We discuss different excitation processes behind the Fe II emission lines in the IUE spectrum of KQ Puppis (Boss 1985), a VV Cephei type of spectroscopic binary. Several pa pers have been published on the subject suggesting a number of processes behind the strong Fe II emission lines. We propose that there are two processes operating: selective photoexcitation by continuum radiation (PCR) from the B-star companion, and photoexcitation by accidental resonance (PAR) by the H Ly alpha radiation field. We suggest excitation channels for each of the Fe II emission lines identified in the spectrum.

    University physics students' explanations of phenomena involving interaction between matter and radiation1999Conference paper (Refereed)
    Abstract [en]

    This project discusses university physics students’ use of models when explaining phenomena involving interaction between matter and electromagnetic radiation. This is a content area which is heavily modelled and appropriate explanations for the chosen phenomena draw upon a number of different models. University physics students are familiar with the phenomena, but they are not generally used as exemplars of scientific models within undergraduate physics education. The data for this study, which is collected during the beginning of 1999, comes from written surveys and interviews. The sample is third year university physics students at different universities in UK and Sweden. Both surveys and interviews have been through a piloting phase.

    University physics students' use of models in explanations of phenomena involving interaction between metals and radiation2001In: International Journal of Science Education, ISSN 0950-0693, E-ISSN 1464-5289, Vol. 23, no 12, p. 1283-1301Article in journal (Refereed)
    Abstract [en]

    We examine third year university physics students' use of models when explaining familiar phenomena involving interaction between metals and electromagnetic radiation. A range of scientific models are available to explain these phenomena. However, explanations of these phenomena tend not to be used as exemplars of scientific models within undergraduate physics education. The student sample is drawn from six universities in UK and Sweden. These students have difficulties in providing appropriate explanations for the phenomena. Many students draw upon the Bohr model of isolated atoms when explaining light emission of metals. The students tend not to recognize that atoms in metals interact to give an electronic structure very different from that of the isolated atom. Few students use a single model consistently in their explanations of these related phenomena. Rather, students' use of models is sensitive to the context in which each phenomenon is presented to them.

    Science in Early Childhood Education – Student teachers’ experiences2016In: Abstract Book, 2016Conference paper (Refereed)
    Abstract [en]

    Develop knowledge about different ways students experience Science in preschool, before and after a onesemestercourse with science content in preschool teacher education. The current national curriculum entails179discussions about pedagogical consequences for preschool and preschool teacher education. Aims for emergentscience, children as 'beings' or 'becomings' (Qvortrup et al. 1994, Eshach, 2006, Fleer, 2013), and teachercompetencies need to be problematized (Roychoudhury, 2012, Sundberg & Ottander, 2013). The theoreticalframework is based on phenomenography focusing on developmental pedagogy (Marton & Booth, 1997,Pramling Samuelsson & Asplund Carlsson, 2008). A questionnaire has been distributed (pre/post) a courseincluding science and practice teaching, in preschool teacher education. A phenomenographic analysis of 107student responses revealing qualitatively different ways of experiencing is analysed for individual shifts. Theresearch adheres to the ethical guidelines of the Swedish Research Council. All participants are informed andagree to voluntary and anonymous participation with right to abandon participation. Many students saw scienceas biology/nature and several did not adjust even though chemistry and physics were taught. Few students werenegative towards science, none after the course. Most students described what and why perspectives, but fewdeveloped a synthesised view.

    The role of science in Swedish pre-schools: student teachers’ attitudes and teaching experiences2014Conference paper (Refereed)
    Abstract [en]

    To investigate how students view the role of science in Swedish pre-schools before and after a semester in pre-service teacher education. A renewed curriculum entails discussions about pedagogical consequences for preschool and pre-school teacher education. Aims for emergent science, children as “being” or “becoming” (Eshach, 2006, Fleer, 2013), practices and teacher competencies need to be problematised. The theoretical framework is based on phenomenography focusing on developmental pedagogy (Marton & Booth, 1997, Pramling Samuelsson & Asplund Carlsson, 2008). A written questionnaire has been piloted and distributed (pre and post) a semester, including science and practice teaching, in pre-service teacher education. A double blind comparative analysis of 107 students aiming to reveal qualitatively different ways of experiencing is presented. The research adheres to the ethical guidelines of the Swedish Research Council. All participants are informed and agree to voluntary and anonymous participation with a right to abandon participation. Preliminary findings show that many students saw science as biology/nature and several did not adjust even though chemistry and physics was taught. Few students were negative towards science - none after the course. Most students described what and why perspectives, but few developed a synthesised view. Both teacher and child centred perspectives were used, and the fraction of the aimed for composite perspectives increased. Explicit aims and appropriate science content in pre-service teacher education are important. Many students remain hesitantly positive towards science, but positive towards practices with children, hence an increased focus on practicing science seems effective.

    Association of TCF7L2 variation with single islet autoantibody expression in children with type 1 diabetes2014In: BMJ open diabetes research & care, ISSN 2052-4897, Vol. 2, no 1, p. 1-6Article in journal (Refereed)
    Abstract [en]

    BACKGROUND: The transcription factor 7-like 2 (TCF7L2) gene has the strongest genetic association with type 2 diabetes. TCF7L2 also associates with latent autoimmune diabetes in adults, which often presents with a single islet autoantibody, but not with classical type 1 diabetes.

    METHODS: We aimed to test if TCF7L2 is associated with single islet autoantibody expression in pediatric type 1 diabetes. We studied 71 prospectively recruited children who had newly diagnosed type 1 diabetes and evidence of islet autoimmunity, that is, expressed ≥1 islet autoantibody to insulin, glutamic acid decarboxylase 65, islet cell autoantigen 512, or zinc transporter 8. TCF7L2 rs7903146 alleles were identified. Data at diagnosis were cross-sectionally analyzed.

    RESULTS: We found that 21.1% of the children with autoimmune type 1 diabetes expressed a single islet autoantibody. The distribution of TCF7L2 rs7903146 genotypes in children with a single autoantibody (n=15) was 40% CC, 26.7% CT and 33.3% TT, compared with children with ≥2 islet autoantibodies (50% CC, 42.9% CT and 7.1% TT, p=0.024). Furthermore, compared with children with ≥2 autoantibodies, single-autoantibody children had characteristics reflecting milder autoimmune destruction of β-cells. Restricting to lean children (body mass index<85th centile; n=36), 45.5% of those expressing a single autoantibody were rs7903146 TT homozygotes, compared with 0% of those with ≥2 autoantibodies (p<0.0001).

    CONCLUSION: These results suggest that, in children with only mild islet autoimmunity, mechanisms associated with TCF7L2 genetic variation contribute to diabetogenesis, and this contribution is larger in the absence of obesity.

    Sea snakes (Serpentes subfamilies Hydrophiinae and Laticaudinae) in Vietnam: a comprehensive checklist and an updated identification key2011In: Zootaxa, ISSN 1175-5326, E-ISSN 1175-5334, no 2894, p. 1-20Article in journal (Refereed)
    Abstract [en]

    Sea snakes (Elapidae, subfamilies Hydrophiinae and Laticaudinae) reach a very high species richness in Southeast Asia, but most countries in the region still lack comprehensive and up-to-date identification tools for these snakes. We present an updated checklist of sea snakes in Vietnam. We also provide diagnostic characters for all species and a new complete identification key, chiefly based on easy-to-use external characters. The checklist and key cover the 25 species documented from Vietnam, as well as three likely future additions to its sea snake fauna. By surveying incoming fishing vessels between Nha Trang and the mouth of Mekong River in 2000-2001, we were able to document two species new for Vietnamese waters: Hydrophis belcheri and H. pachycercos. Through these surveys we also secured four specimens of the rare endemic species H. parviceps, formerly known only from two specimens. A comprehensive bibliography of the literature treating sea snakes in Vietnamese waters is provided.

    Patienters upplevelser av isolering vid infektionssjukdom: en litteraturstudie2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Bakgrund: Idag är det allt mer förekommande med utbrott av multiresistenta stammar på sjukhus, det blir då ett ökat behov av att patienter trots vårdform ska vårdas inom isolering. Smittsamma infektionssjukdomar kräver isolering för att förhindra spridning av infektion. Syfte: Syftet med studien var att beskriva patienters upplevelser av isolering vid infektionssjukdom på sjukhus. Metod: Studien har genomförts som en allmän litteraturstudie som baseras på tio vetenskapliga artiklar. Datainsamlingen har gjorts i Cinahl Complete och Pubmed. Granskningen av artiklarna gjordes genom Kristianstad Högskolas granskningsmall. Resultat: Patienternas upplevelser av isolering vid en infektionssjukdom kunde delas upp i tre huvudkategorier och nio subkategorier. Känslor i samband med isolering: Smittsam och smutsig, diskriminering, ensamhet. Att vara inlåst: Instängd och övergiven, begränsad, konsekvenser och isoleringsrummets betydelse. Mötet med sjuksköterskan:Informationsbrist och bemötande. Diskussion: Patienter med infektionssjukdom som kräver isolering upplevde i stor utsträckning att hälso- och sjukvårdspersonal saknade kunskap om deras infektionssjukdom och om riktlinjer vid isolering och att deras upplevelse av diskriminering stärktes för att de blev åtskilda från andra patienter. Det är viktigt att sjuksköterskan har kunskap om patienters upplevelser av isolering vid infektionssjukdom för att kunna ge de en god omvårdnad och en jämlik vård.

    Är attityder till reklam kring skönhetsprodukter beroende av självkänsla?2005Independent thesis Basic level (degree of Bachelor)Student thesis
    Abstract [sv]

    Denna undersöknings syfte är att studera om attityden till reklamens två informationstyper skiljer sig åt. De två informationstyperna är individeffekterna och produktegenskaperna. Det var även intressant att se om attityder till reklam för skönhetsprodukter är beroende av självkänslan och om individers attityd till reklam beror på vilket gymnasieprogram de läser. I undersökningen deltog 60 försökspersoner som läser på gymnasiet. Av de 60 deltagarna läser 30 på det naturvetenskapliga programmet och resterande 30 på det samhällsvetenskapliga programmet med inriktningen ekonomi. Undersökningen genomfördes med hjälp av en enkät som bestod av 25 påståenden. Dessa var indelade i en del som gällde attityder och en som gällde självkänsla.

    Resultatet visade att attityden till reklamens individeffekter var mindre positiv än attityden till reklamens produktegenskaper och att attityd till reklamens individeffekter korrelerade med självkänsla i en negativ riktning. Ju högre självkänsla individen har desto mer negativ attityd har den till individeffekterna. Vidare visades att det inte fanns någon skillnad i attityd till reklamens individeffekter mellan individer som gick på olika gymnasieprogram och ej heller mellan könen. Resultaten diskuteras i termer av reklamens informationstyper och självkänsla.

    Att ändra fokus från extra anpassningar till ledning och stimulans: att höja elevernas måluppfyllelse2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syftet med studien är att få syn på hur två skolor arbetar för att skapa en gemensam plattform för att tolka styrdokument utveckla samsyn kring begreppen ledning och stimulans och extra anpassningar. Detta för att skapa inkluderande lärmiljöer som i sin tur leder till, ökad måluppfyllelse hos eleverna då verksamheten utifrån alla tre nivåer organisation-, grupp- och individnivå reflekterar, kritiskt granskar lärande, undervisning och ledarskap. Vår studie baseras på tidigare forskning med utgångspunkt från sociokulturellt-, specialpedagogiskt-, och organisation och ledarskapsperspektiv. Det sociokulturella perspektivet utgår från Vygotskij (2001) tankar kring de sociala faktorernas betydelse för hur vi människor utvecklas socialt och kognitivt. Det specialpedagogiska perspektivet ger olika tolkningar Ahlberg (2007) benämner två riktningar inom detta synsätt som det kategoriska respektive relationella. I det kategoriska perspektivet är det individen som är bärare av problemet medan i det relationella ser man att problematiken finns i lärmiljön. Studien kom att ha sitt främsta fokus på det relationella perspektivet. Organisationsperspektivet hjälper till att se och förstå ledarens roll och påverkan på alla tre nivåerna inom verksamheten. Studien utgår från en kvalitativ metod med semistrukturerade intervjuer och icke-deltagande observationer. Studiens resultat visar bland annat på vikten av en tydlig struktur, delaktighet för att skapa en känsla av sammanhang relationellt förhållningssätt.

    Who are we loyal to?: an exploratory study about how collaborations between influencers and brands impact brand loyalty2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Social media has enabled people to interact and establish relationships on online platforms

    such as Instagram. Consequently, brands begun to collaborate with influencers on Instagram

    in order to reach existing and potential customers on this platform. However, due to

    influencers power on Instagram, it has become important for brands to choose the right

    influencer and ensure customers’ development of loyalty. Therefore, the purpose  of this thesis

    is to explore how collaborations between brands and influencers on Instagram impact brand

    loyalty and the loyalty towards the influencer.

    This thesis was conducted through a qualitative  approach, an abductive reasoning and with

    the use of a case study on the influencer: Kenza Zuiten Subosic. Three focus groups where

    guided by the case study on Kenza and consisted of participants who follow her on Instagram.

    The findings  show that the match between the brand and influencer, the sharing of trustworthy

    posts through custom content, and personality has an impact on brand loyalty and the loyalty

    towards the influencer. These findings contribute  to marketers who aim to develop customer

    loyalty and establish relationships through Instagram. Additionally, this thesis adds original

    value to the field of loyalty as previous studies provide limited research on the development

    of loyalty through collaborations on Instagram.

    Kundlojalitet: en studie om vad banker gör för att optimalt uppnå lojalitet via kundrelationer2012Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Banksektorn har en betydande inverkan i vårt vardagsliv, då den uppfyller viktiga funktioner för oss individer. Teknik- samt marknadsföringsutveckling har bidragit till en situation med ökad konkurrens mellan banker där kundens val av bank baseras på tillfredsställelse. Kundlojalitet är ett välkänt nyckelbegrepp med flera definitioner. Uppsatsen kommer att ge läsaren en övergripande bild av vad banker gör för att optimalt uppnå kundlojalitet.

    Även om ambitionen för alla analyser är att ha en stor inklusionsbas har utformning av denna studie ställt krav på stoleken av analysen, vilket medfört att studien begränsats till två banker; Svenska Handelsbanken och Skandinaviska Enskilda Banken (SEB) i Malmö, som är etablerade och bedöms vara representativa banker för sektorn.

    Syftet med uppsatsen är att via modellen "Customer Relationship Management" identifiera på vilket sätt effekterna av bankens fokus och nerlagda vikt på kundrelationer leder till kundlojalitet. Undersökningen genomförs via den kvalitativa metoden och har avsikt att öka kunskapen inom gränserna för ovannämnda ämne.

    Rapporten består av två modeller som utformats av tidigare forskning. Analys har genererat ett förslag av en ny modell som speglar empirin. I korthet visar resultatet att en stark kundrelation skapar förtroende för banken och därmed genererar kundlojalitet.

    Hanterandet av koleran i Karlskrona: en studie om de skyddsåtgärder som vidtogs i Karlskrona under åren 1834 och 18532011Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syftet med uppsatsen var att undersöka vilka åtgärder Karlskrona vidtog kring kolerafarsoten år 1834 och 1853 samt vilka reaktioner som uppstod kring åtgärderna hos stadens invånare.

    Materialet som använts består främst av sundhetsnämndens handlingar från åren 1834 och 1853, kungörelser kring koleran och tidningsartiklar från dagstidningarna Carlskrona Veckoblad samt Blekings-Posten.

    Resultatet visar att Karlskrona vidtagit förebyggande åtgärder år 1834 från den stund då koleran nått Ystad. Tidigt inrättades och iordningställdes sjukhusanstalter, tillförsel av sjukhuspersonal, beredskap av likkistor, särskilda kolerabegravningsplatser, karantän och vakthållning. Övervakandet av ordning och renlighet utgjordes av inrättade kvartersmännen. Karlskrona strävade efter att noggrant kontrollera vilka personer som intog staden. Läkarnas insatser tyder på att de förespråkade att förebygga smittspridningen i staden främst bland stadens fattigare befolkning. Skyddsåtgärderna som vidtogs av Karlskrona år 1834 levde kvar i 1853 års skyddsåtgärder. Sundhetsnämndens verksamhet år 1853 visar att de flesta skyddsåtgärder inrättats efter att koleran utbrutit i staden, men att verksamheten handlade aktivt när koleran utbrutit i staden. Tillsyningsmän och ledamöter uppmanades kontrollera renligheten inom sjukkvarteren varav böter utdelades till personer som inte erhöll renlighet. Rökning och rening var skyddsåtgärder som ansågs kunna reducera smittspridningen. Oron om att smittspridningen skulle få förödande konsekvenser bland stadens fattigare befolkning levde kvar hos läkarna år 1853. För att hjälpa samhällets mest utsatta anskaffades friskt vatten för att förhindra förödande konsekvenser.

    Ett orättvist betygssystem?: Gymnasielärares syn på betygsättning inom Idrott & Hälsa2011Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Tidigare forskning visar att elever anser att betygen i det nuvarande målrelaterade betygssystemet är orättvisa och att lärare utgår ifrån andra aspekter vid betygsättningen än att betygsätta elevernas kunskaper. Därmed valde vi att undersöka hur lärares bedömning och betygsättning utförs bland behöriga lärare för att få klarhet i om det nuvarande betygssystemet är ett rättvist betygssystem.

    Syftet med studien är att undersöka vilka aspekter som behöriga gymnasielärare i ämnet idrott och hälsa gör sin bedömning och betygsättning utifrån. Fokus riktas även åt att granska hur lärarna säger sig bedöma olika moment i undervisningen och vilka uppfattningar lärarna har kring det målrelaterade betygssystemet. Studien består av en kvalitativ undersökning i form av semistrukturerade intervjuer med sju behöriga lärare i idrott och hälsa på gymnasiet.

    Studien visar att de behöriga lärarna i idrott och hälsa bedömer och betygsätter utifrån andra än gällande aspekter. Lärarna säger sig bedöma kondition och styrka utifrån olika tester i form av resultat för att kunna mäta elevernas utveckling av den fysiska statusen. Lärarna uppger att det nuvarande betygssystemet innehåller för få steg och att rättvisa betyg därmed inte kan sättas. Det framhävs av lärarna att lärare i samma ämne bör samarbeta och föra kontinuerliga diskussioner för att likvärdig och rättvis bedömning och betygsättning ska kunna nås upp till.

    Biology and history in eastern Asian landscapes compared with Europe2012In: The 55th symposium of the international association for vegetation science: climate change and vegetation science / [ed] Eun Ju Lee, Hyesoon Kong, Kang-Hyun Cho, Yowhan Son, Jang-Geun Oh, Do-Soon Cho, Jong-Won Kim, Sun-Kee Hong, 2012Conference paper (Other academic)
    Abstract [en]

    This project is a continuation 0f Urban Emanuelsson's book "The rural landscapes of Europe - How man has shaped European nature" from 2009 which was written from a biological-historical perspective. In eastern Asia climate is roughly comparable with Europe, and both areas have long and independent land use traditions. Vegetation patterns can also be compared although differences are also pronounced and eastern Asia more species rich. Rice and millet/wheat production developed in both areas as well as societies relying on nomadic animal rearing. Human development has, however, been highly independent in the two areas, which makes comparisons interesting. In this project eastern Asia (roughly China north of Chang Jiang, Mongolia, SE Russia from Buryatia ta Primorye, Korea and Japan) and Europe (within its historical borders) will be compared.

    Some factors that have led to different landscape patterns in the two areas are:

    • Different attitudes towards grazing stock

    • Different attitudes towards forest

    • Different food cultures

    • Different routes and timing of cultural influence from other areas

    • Different kinds of religious conceptions about the landscape

    • Different kinds of major political movements during the past 100 years

    We work in a distinctly interdisciplinary way, and the interaction of environmental and social factors behind landscape changes is in focus. Archaeology and the geological and climate-related basis for the biodiversity are being addressed, followed by descriptions of cultural variation and different forms of land-use. Timing and reasons for the introduction of agriculture in different areas is of particular interest. Competition between grazing, agriculture, forest use and other land-use, is being described, particularly along ecological border zones, as well as the effects on the landscape by religious conceptions. How the biota has changed through time, often drastically so, is being described in relation to both human interference and climate and other changes. Historical influence of land use and the present day landscapes, also where these are apparently or allegedly "natural" is of particular concern. The current situation will be discussed, and weight given to how the landscape today can be used for recreation and tourism.

    Progress is made through field visits and literature studies. The end product will be a book with co-authorship of scholars within the region to be published within two years time.

    Dendrokronologisk undersökning av granbeståndet i Siggaboda naturreservat2013Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Med hjälp av såg- och borrprover studerades åldern på 41 granar och en tall i Siggaboda naturreservat i sydligaste Småland, med syfte att undersöka granens etablering och döende på lokalen. Vidare har reservatet delats in i tre områden för att undersöka om några geografiska skillnader i granarnas etablerings- och dödsår förekommer. Analysarbetet utfördes på Nationella laboratoriet för vedanatomi och dendrokronologi vid Lunds universitet. På lokalen har tidigare bland annat en pollenanalys utförts (Björkman & Bradshaw 1996) samt en kombinerad pollenanalytisk och dendrokronologisk studie (Hannon et al. 2010). Enligt dessa har granen etablerats i Siggaboda under sista halvan av 1700-talet. Någon undersökning med sågprover som material har tidigare inte genomförts på lokalen.

    Resultaten visar att det äldsta trädet grodde runt 1771 och att en kraftig expansion skedde under mitten av 1800-talet. De visar även att merparten av granarna har dött mellan åren 2005 och 2008, vilket indikerar att granbarkborre etablerade sig till följd av januaristormen 2005 och därefter spred sig även till stående träd - något som har fått omfattande konsekvenser för granarna i reservatet.

    Blooms of sequence-specific culturable bacteria in the sea1993In: FEMS Microbiology Letters, ISSN 0378-1097, E-ISSN 1574-6968, Vol. 102, no 3-4, p. 161-166Article in journal (Refereed)
    Abstract [en]

    Using specific deoxyoligonucleotide probes we have discovered seasonally strong (up to ∼ 100%) dominance of bacteria hybridizing to a single probe, in near shore waters off Scripps pier (32°53′N; 117°15′W). The probes were designed from partially sequenced 16S rRNA (V3 domain) of isolated marine bacteria. The results indicate that this approach may be used for studies of bacterial populations in the marine environment. We have shown that a number of genotypes that at times are dominant in the natural assemblages are culturable (and not, ‘viable-but-unculturable’). Additionally, our data suggests that the discrepancy between viable counts and direct counts in sea water samples can be explained by low plating efficiency.

    Identification of Vibrio anguillarum in fish by using partial 16S rRNA sequences and a specific 16S rRNA oligonucleotide probe1989In: Applied and Environmental Microbiology, ISSN 0099-2240, E-ISSN 1098-5336, Vol. 55, no 8, p. 1907-1910Article in journal (Refereed)
    Abstract [en]

    16S rRNA from seven different Vibrio anguillarum strains was partially sequenced and compared. From this sequence information we could design a 25-base-long oligonucleotide and use it as a specific probe for identification of V. anguillarum. This was determined by RNA-DNA colony hybridization and slot-blot hybridization. Strong, specific hybridization to the probe was observed for all V. anguillarum strains tested. Furthermore, no cross-hybridization could be seen against five other bacterial species. The detection limit was 5 x 10(3) bacteria per ml. It was even possible to detect V. anguillarum, by slot-blot hybridization, directly in a homogenized kidney from a fish that had died of vibriosis. The partial sequence information revealed small but significant differences between strains of the same species. These sequence differences are sufficiently significant to allow serotyping on the RNA level. Comparing strains of different serotypes revealed a 10-base and an 11-base difference in V. anguillarum serotypes O8 and O9, respectively, in a 122-base partial sequence.

    Att handleda akademiskt skrivarbete: intervjuer av handledare inom naturvetenskap och naturvetenskaplig didaktik2012In: Högskolepedagogisk debatt, ISSN 2000-9216, no 1, p. 9-21Article in journal (Other academic)
    Abstract [sv]

    Det är viktigt att kunna skriva på ett tydligt och övertygande sätt för att lyckas som forskare, en sanning som även gäller inom icke humanistiska discipliner som naturvetenskap och naturvetenskaplig didaktik. Som handledare måste man med andra ord kunna handleda sina forskarstudenter i skrivandets konst. Trots detta förekommer det i stort sett ingen utbildning i hur man handledare forskarstudenter i skrivarbetet. I denna undersökning har jag intervjuat fyra naturvetenskapliga handledare och fyra handledare inom naturvetenskaplig didaktik. Syftet var att försöka få en bild av hur handledare hanterar de språkliga problem som deras forskarstudenter haft och se om det fanns någon skillnad i hur handledning går till inom de två disciplinerna. Generellt visar resultatet av studien att problem med skrivprocessen är mycket likartad hos de två handledargrupperna, även om de till vissa delar arbetar olika. Slutsatsen från intervjuerna är att det är tveksamt om man kan säga att en forskarstuderande har uppnått högskoleförordningens mål, eftersom många gånger handledaren står för en stor andel av texterna. Slutligen ges förslag till värderingskriterier som kan användas av enskilda handledare vid handledning av forskarstuderande i akademiskt skrivarbete.

    Man and Biosphere Health: en komplett akademisk miljö2018Collection (editor) (Other academic)
    Abstract [sv]

    Inom forskningsmiljön Man and Biospere Health, förkortat MABH (hkr.se/mabh), bedrivs forskning inom biologi, kemi, biomedicin och psykologi, men också mycket tvärvetenskaplig forskning, med fokus kring människans påverkan på ekosystem och dess effekter på biologiskt liv, mångfald och hälsa. Forskare inom MABH är också involverade i åtgärdsprogram och utveckling av nya tekniker och metoder för att kunna undersöka de negativa effekterna av människans aktiviteter. Forskningsmiljön MABH bildades 2009 med syfte att samla högskolan forskning inom bland annat ekologi, miljöteknik, kemi och biomedicin under ett paraply. Ambitionen var att utveckla tvärvetenskapliga projekt såväl inom som utanför gruppen.

    Defining the niche of Vibrio parahaemolyticus during pre- and post-monsoon seasons in the coastal Arabian Sea2014In: Microbial Ecology, ISSN 0095-3628, E-ISSN 1432-184X, Vol. 67, no 1, p. 57-65Article in journal (Refereed)
    Abstract [en]

    The bacteria Vibrio parahaemolyticus is an important component of coastal ecosystems worldwide, and in recent years, V. parahaemolyticus has caused several cases of food-borne gastroenteritis. However, research investigating which parameters are important in regulating V. parahaemolyticus abundance in tropical areas with relatively stable temperatures and salinity are largely lacking. The objective here was to investigate which environmental forces are driving elevated abundances of V. parahaemolyticus in a tropical oligotrophic coastal area in the Arabian Sea. We analysed a large number of environmental parameters in parallel with cell densities of V. parahaemolyticus and Vibrio spp. Abundance data was obtained using real-time PCR, during two different sampling periods, representative for two distinct seasons. Water temperature and salinity were stable during and between sampling periods, but V. parahaemolyticus abundances were on average six times higher during the first sampling period in December, compared to the second period in February–March. V. parahaemolyticus abundance was found to be positively correlated to inorganic phosphate concentration and copepod abundance. We thus hypothesise that these are important factors regulating V. parahaemolyticus abundance in coastal tropical areas during these periods.

    ESBL resistance patterns among environmental and clinical bacterial isolates2017Conference paper (Other academic)
    Abstract [en]

    Objectives

    We have studied the phenotypic and genetic pattern among Extended Spectrum Beta-lactamase (ESBL) producing bacteria in the aquatic environment, and have compared the result with clinical samples from the same area.

    Methods

    Water samples have been collected at three different sites in the Helge river, Kristianstad community, Sweden. The first station is located before the outlet from the municipal sewage plant, the second just after the outlet and the third close to the Baltic Sea. Cultured bacterial isolates from the water and clinical isolates were analysed for phenotypic expression of ESBL related genes using the MAST-test, and genetically by PCR analyses of a set of ESBL genes, i.e. blaCTX-M, blaSHV, blaTEM, and blaOXA  

    Results

    Both clinical and environmental ESBL isolates were dominated by Escherichia coli and Klebsiella pneumoniae. Highest abundance of environmental ESBL isolates were obtained from the station close to the sewage outlet, the lowest close to the Baltic Sea. The gene cluster blaCTX-M was the most common among all isolates (65%), followed by blaTEM (30%).  The blaOXA and blaSHV genes were more common in clinical isolates.

    Conclusion

    A majority of the ESBL bacteria were mediated by chromosomal genes, dominated by blaCTX-M. However, blaOXA .and blaSHV were more common in clinical isolates. Further genetic analyses will be performed on more isolates, and on total bacterial community DNA.
