    Relationships between models used for teaching chemistry and those expressed by students2012Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    This thesis is focused upon chemistry as a school subject and students' interpretations and use of formally introduced teaching models. To explore students' developing repertoire of chemical models, a longitudinal interview study was undertaken spanning the first year of upper secondary school chemistry. Matter in its different states was selected as the target framework for this study. The results presented are derived from both generalisations of groups of students as well as a case study describing an individual learner's interpretation of formal content. The results obtained demonstrated that the formal teaching models provided to the students included in this study were not sufficient to afford them a coherent framework of matter in its different states or for chemical bonding. Instead, students' expressed models of matter and phase change were to a high degree dependent on electron movement (Paper I), anthropomorphism (Paper II) and, for one student, a mechanistic approach based on small particles and gravitation (Paper III). The results from this study place focus on the importance of learners' prior learning (previous experiences) and the need to develop a coherent framework of formal teaching models for the nature of matter and phase change.

    Developing an Understanding of Chemistry: A case study of one Swedish student's rich conceptualisation for making sense of upper secondary school chemistry2014In: International Journal of Science Education, ISSN 0950-0693, E-ISSN 1464-5289, Vol. 36, no 7, p. 1107-1136Article in journal (Refereed)
    Abstract [en]

    In this paper, we report a case study of a 16-year-old Swedish upper secondary student's developing understanding of key concept areas studied in his upper secondary school chemistry course. This study illustrates how the thinking of an individual learner, Jesper, evolves over a school year in response to formal instruction in a particular educational context. Jesper presented a range of ideas, some of which matched intended teaching whilst others were quite inconsistent with canonical chemistry. Of particular interest, research data suggest that his initial alternative conceptions influenced his thinking about subsequent teaching of chemistry subject matter, illustrating how students' alternative conceptions interact with formal instruction. Our findings support the claims of some researchers that alternative conceptions may be stable and tenacious in the context of instruction. Jesper's rich conceptualisation of matter at submicroscopic scales drew upon intuitions about the world that led to teaching being misinterpreted to develop further alternative conceptions. Yet his intuitive thinking also offered clear potential links with canonical scientific concepts that could have been harnessed to channel his developing thinking. These findings support the argument that identifying students' intuitive thinking and how it develops in different instructional contexts can support the development of more effective science pedagogy.

    Learners' Mental Models of the Particle Nature of Matter: A study of 16-year-old Swedish science students2009In: International Journal of Science Education, ISSN 0950-0693, E-ISSN 1464-5289, Vol. 31, no 6, p. 757-786Article in journal (Refereed)
    Abstract [en]

    The results presented here derive from a longitudinal study of Swedish upper secondary science students' (16-19 years of age) developing understanding of key chemical concepts. The informants were 18 students from two different schools. The aim of the present study was to investigate the mental models of matter at the particulate level that learners develop. Data were collected using semi-structured interviews based around the students' own drawings of the atom, and of solids, liquids, and gases. The interview transcripts were analysed to identify patterns in the data that offer insight into aspects of student understanding. The findings are discussed in the specific curriculum context in Swedish schools. Results indicate that the teaching model of the atom (derived from Bohr's model) commonly presented by teachers and textbook authors in Sweden gives the students an image of a disproportionately large and immobile nucleus, emphasises a planetary model of the atom and gives rise to a chain of logic leading to immobility in the solid state and molecular breakdown during phase transitions. The findings indicate that changes in teaching approaches are required to better support learners in developing mental models that reflect the intended target knowledge.

    Designing play-based learning chemistry activities in the preschool environment2019In: Chemistry Education Research and Practice, ISSN 1756-1108, E-ISSN 1756-1108Article in journal (Refereed)
    Abstract [en]

    This study focuses on the design of play-based learning activities for chemistry in preschool. Viewing chemistry as a part of our past and present culture instead of as a subject, provides the backdrop for a more holistic approach to chemistry within this specific environment. A cultural-historical perspective, together with scaffolding, emergent science skills and sustained shared thinking, made up the framework for the design of the learning activities. Results show that when scaffolding and emergent science skills are used within the design, they provide good support for both the content and the teacher in the actual learning situation. Working with scaffolding was also beneficial for professional development. However, for a progressive and inclusive activity design, it is essential to take into account aspects of the immediate environment and methods for direct evaluation.

    Inverse analyses of effective diffusion parameters relevant for a two-phase moisture model of cementitious materials2018In: Cement and Concrete Research, ISSN 0008-8846, E-ISSN 1873-3948, Vol. 106, p. 117-129Article in journal (Refereed)
    Abstract [en]

    Here we present an inverse analyses approach to determining the two-phase moisture transport properties re-levant to concrete durability modeling. The purposed moisture transport model was based on a continuumapproach with two truly separate equations for the liquid and gas phase being connected by the sorption ki-netics. The moisture properties of ten binder-systems containingfly ash, calcined clay, burnt shale and graymicro-filler, were investigated experimentally. The experiments used were, (i) sorption test (moisturefixation),(ii) cup test in two different relative humidity intervals, (iii) drying test, and, (iv) capillary suction test. Masschange over time, as obtained from the drying test, the two different cup test intervals and the capillary suctiontest, was used to obtain the effective diffusion parameters using the proposed inverse analyses approach. Themoisture properties obtained with the proposed inverse analyses method provide a good description of the testperiod for the ten different binder-systems.

    Pore-scale modeling of vapor transport in partially saturated capillary tube with variable area using chemical potential2016In: Water resources research, ISSN 0043-1397, E-ISSN 1944-7973, Vol. 52, no 9, p. 7023-7035Article in journal (Refereed)
    Abstract [en]

    Here we illustrate the usefulness of using the chemical potential as the primary unknown by modeling isothermal vapor transport through a partially saturated cylindrically symmetric capillary tube of variable cross-sectional area using a single equation. There are no fitting parameters and the numerical solutions to the equation are compared with experimental results with excellent agreement. We demonstrate that isothermal vapor transport can be accurately modeled without modeling the details of the contact angle, microscale temperature fluctuations, or pressure fluctuations using a modification of the Fick-Jacobs equation. We thus conclude that for a single, axisymmetric pore, the enhancement factor depends upon relative humidity boundary conditions at the liquid bridge interfaces, distance between liquid bridges, and bridge lengths.

    Service Availability in Cloud Computing: Threats and Best Practices2013Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Cloud computing provides access to on-demand computing resources and storage space, whereby applications and data are hosted with data centers managed by third parties, on a pay-per-use price model. This allows organizations to focus on core business goals instead of managing in-house IT infrastructure.                    

    However, as more business critical applications and data are moved to the cloud, service availability is becoming a growing concern. A number of recent cloud service disruptions have questioned the reliability of cloud environments to host business critical applications and data. The impact of these disruptions varies, but, in most cases, there are financial losses and damaged reputation among consumers.        

    This thesis aims to investigate the threats to service availability in cloud computing and to provide some best practices to mitigate some of these threats. As a result, we identified eight categories of threats. They include, in no particular order: power outage, hardware failure, cyber-attack, configuration error, software bug, human error, administrative or legal dispute and network dependency. A number of systematic mitigation techniques to ensure constant availability of service by cloud providers were identified. In addition, practices that can be applied by cloud customers and users of cloud services, to improve service availability were presented.

    Kan manuell analys av Csv-EPK ersättas med automatiserad analys på Sysmex XN-1000?2016Independent thesis Basic level (degree of Bachelor), 180 HE creditsStudent thesis
    Abstract [en]

    Determination of erythrocyte count in cerebrospinal fluid (CSF-EPC) is used to exclude various intracranial hemorrhage, especially subarachnoid hemorrhage (SAH). SAH means a bleeding between the pia mater and arachnoidea which occurs due to rupture of an aneurysm in the subarachnoid space. Manual counting of erythrocytes in the cerebrospinal fluid with Bürkers chamber and microscopy has been the gold standard for the past decades, but the manual method is time consuming and requires great experience. The purpose of this study was to evaluate if manual analysis of  CSF-EPC with counting chamber, and light microscopy can be replaced by automated analysis of CSF-EPC with Hematology Analyzer XN-1000 (Sysmex). Fortyeight cerebrospinal fluid samples with various concentrations of erythrocytes ware prepared by diluting known concentration of erythrocytes in cell-free CSF. Prepared CSF-samples with added erythrocytes were analyzed first on the XN-1000. Thereafter, manual counting of erythrocytes was performed using Bürkers counting chamber. A linear regression was established to describe the correlation between the automated analysis of the CSF-EPC and manual analysis of the CSF-EPC. Imprecision in the analysis of the CSF-EPC on the XN-1000 (Sysmex) was assessed by within-run imprecision. A very good correlation (r = 0.999) was found between the XN-1000 and manual counting. For results in the lower range, 100 - 5000 (106/L), correlation was also good (r = 0.997). The coefficient of variation was 19,8 % at CSF-EPC of 370 x 106/L and 3.1 % at CSF-EPC of 25 950 x 106/L. The sensitivity for analysis of CSF-EPC on XN-1000 was 370 x 106/L. The conclusion is that the analysis of Csv-EPC on XN-1000 can be used for clinical diagnostics of CSF- samples. However, it should be noted that XN-1000 has poor sensitivity for low CSF-EPC values < 370 x 106/L. To ensure high diagnostic quality even in CSF-samples with low erythrocyte counts are recommended a reference limit of < 500 x 106/L as a practical cut off for supplemental microscopic counting in routine healthcare laboratories.

    Isolering och identifiering av bakterie som orsakar missfärgning på kött2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Meat is skeletal muscle from different animals, such as pigs, cattle or sheep. Pseudomonas are bacteria that may cause food spoilage. The bacteria live in our environment and can cause problems due to biofilm formation in hospitals and industries. The slaughterhouse KLS Ugglarps has found that some pig cuttings have become discolored with at blue color and they wanted to find out what caused it. Pseudomonas aeruginosa had previously been found in the production area and was suspected as the cause.Meat, with and without discoloration, was investigated using various microbiological methods to see which bacterium cause the blue color. Different colonies were isolated and identified. The methods used were API 20NE, gram staining and oxidation test. A reference isolate was used as control. It was found that it was not P. aeruginosa but instead Pseudomonas fluorescens that caused the blue color. This was confirmed by applying the isolated bacteria to sterile meat and the blue color did appear after incubation. A screening for the source of contamination was performed in the production area to see if the bacterium could be found before start-up and during production. The samples taken showed that there were bacteria at both time points and that the production surfaces at the beginning of the production line were more prone to contamination than the other surfaces.

    Barnets bästa i umgänges– och vårdnadstvister: En diskursanalys av svenska domstolars resonemang2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The aim of this study was to analyse how Swedish courts reason about the child's best in custody and access disputes. We have assumed different themes to analyse our empirical data, these themes were the child's best interests, perspective on the child's best interests, child's perspective, children as subjects or objects and finally the right of the child or the child's best interests. Our empirical data have consisted of 15 City Court and Court of Appeal judgments of the Swedish courts handed down in 2015. The study had a qualitative disposition and the selection was made strategically to make sure the empirical data would be relevant to our issues. We have used a discourse analysis where the intention was to study how the court reason about the child’s interests and what statements that gets preference and what gets excluded in the assessment. Our theoretical starting point was extracted from Foucault’s theory about power and his discourse concept. We have used the concept of his theory in our analysis, but also extracted the theoretical concepts from previous research. The result shows that the Court's assessment of what is in the child’s best interest is based primarily on a professional and adult perspective on the child's situation. The individual child's perspective was excluded and the Court was principally talking about children's needs and interests in general. The result also showed that children were seen as objects and not as participants in the majority of the cases.

    Tvåspråkiga elever: En undersökning om elevers inställning till sin tvåspråkighet.2011Independent thesis Advanced level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syfte: Syftet med den här studien är att ta reda på hur elever med svenska som andra språk, beskriver sina erfarenheter av att vara tvåspråkiga. Syftet med studien är också att ta reda på vad fördelarna respektive nackdelarna är att vara tvåspråkig i skolan.

    Metod: Undersökningsmetoden för studien är en kvalitativ metod med intervjuer av fem informanter.

    Resultat: Studien visar att elevers förhållningssätt gentemot sin tvåspråkighet är positiv. Eleverna anser att kunna två språk är en fördel samt att det leder färdigheter av förståelse av andra kulturer och kunskap i andra ämnen. Att bevara modersmålet anses också något som en viktig del av elevernas inställning till sina två språk vare sig det gäller att man förstärker den genom sin omgivning eller i undervisning. Omgivningen lägger också mycket intryck på deras tvåspråkighet, där positiva fördelarna också framhävs mer genom att eleverna aktivt använder språket med familjen, vänner och i skolan.

    Mobbning i skolan: Elevers hälsa och de olika mobbningsstrategierna2011Independent thesis Basic level (professional degree), 15 credits / 22,5 HE creditsStudent thesis
    Abstract [sv]

    Bakgrund: I dagens skola finns det elever som tyvärr blir trakasserade av andra elever. Mobbning är ett problem som existerar i dagens skola som behöver lyftas fram samt där alla inom skolverksamheten blir medvetna om vad mobbning kan orsaka för negativa effekter.

    Syfte: Vi vill med denna litteraturstudie undersöka hur mobbning kan påverka barn och ungdomars hälsa samt undersöka hur olika metoder och strategier av mobbning används för att mobba.

    Metod: Det här är en systematisk litteraturstudie där vi sökte inom databaserna: ELIN, ERIC och Libris. Vi har använt oss av sju olika vetenskapliga artiklar i vår studie.

    Resultat: Vi har med vår litteraturstudie kommit fram att ungdomars psykiska hälsa påverkas starkt av mobbning oberoende om man är offer till mobbning eller en mobbare som utför trakasserier. I vår undersökning har vi även funnit att metoden för att utföra mobbning via nätet samt användningen av elektronik är en strategi för att trakassera individer.

    Slutsats: Dagens skola behöver vara uppmärksam att mobbning kan förekomma ur olika strategier. Nätmobbning ingår i den verbala mobbningen. Det är ett nytt och modern sätt för ungdomarna att använda sig av för att hota och trakassera en individ. Men också en av de lättaste att upptäcka än exempelvis tyst mobbning samt är en av de enklaste att upptäcka. Det är också viktigt att påpeka att individer oavsett de som blir utsatta av mobbning och de som utför handlingarna inte mår bra av mobbning.

    Libyenkrisen – en humanitär intervention?: En kvalitativ textanalys som syftar till att förklara motiven bakom NATO:s och FN:s beslut att intervenera Libyen2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Humanitarian intervention is a concept that generates several problems in our time. The idea of humanitarian intervention concerns the modern norms of sovereignty and noninterventional principals. It also concerns the conventional norm, which declares that states are not allowed to interfere in other states’ internal affairs. The use of military force to implement humanitarian intervention is restricted according to international law. This is what this thesis intends to investigate. The purpose was to find out the causes behind the intervention in Libya, which was carried out by NATO. The main questions were (1) to find out if the intervention in Libya was a humanitarian intervention (2) or if there were other motives that were behind the intervention. Two classical international relations theories have been utilized for the analysis. The analysis focused on the five UN Security Council members’ statements and arguments, which have been expressed in the UN Security Council. This issue created a gap between the members of the Security Council, especially between the Western states and the Russian and Chinese authorities

    Probabilistic Analysis of the EPR-Bohm Experiment2007Licentiate thesis, monograph (Other academic)
    Abstract [en]

    Bell's Theorem was developed on the basis of considerations

    involving a linear combination of spin correlation functions, each

    of which has a distinct pair of arguments. The simultaneous

    presence of these different pairs of arguments in the same

    equation is investigated, and the implicit counterfactual

    assumption in Bell's theorem is discussed.

    We show how an explicit contextuality can arise from a model

    displaying unfair sampling, and we discuss it in the

    framework of David Mermin's cleverly simple version of Bell's

    theore, which pinpoints in a very straightforward way how

    interpreting entanglement from a realistic point of view can be

    problematic. We present an extended version of Mermin's device

    that can actually be given a straightforward realistic

    interpretation.

    We stress that the low efficiency of detectors in all experiments

    with photons makes the use of the fair sampling assumption

    unavoidable. Since this very assumption is false in all existing

    local realistic models based on inefficient detection, we thus

    question its validity. We show that it is no more reasonable to

    assume fair sampling than it is impossible to test, and we

    actually propose an experimental test which would provides clear

    cut results in case of unfair sampling

    We then analyze optical EPR experimental data performed by Weihs et al in Innsbruck 1997-1998. We show that for some linear

    combinations of the raw coincidence rates, the experimental

    results display some anomalous behavior that a more general source state (like non-maximally entangled state) cannot

    straightforwardly account for. We use the fair sampling

    assumption, and assume explicitly that the detection efficiencies

    for the pairs of entangled photons can be written as a product of

    the two corresponding detection efficiencies for the single

    photons. We show that this explicit use of fair sampling cannot be

    maintained to be a reasonable assumption as it leads to an

    apparent violation of the no-signalling principle.

    Abstract [en]

    We have previously shown that the use of the fair sampling assumption in EPR experiments could be questioned on the basis of experimental data. We continue our analysis of the data from the optical EPR experimental performed by Weihs et al. in Innsbruck 1997-1998, and we discuss whether a non-rotationally invariant source can account for the experimental results.

    Abstract [en]

    We present some recent results of a new statistical analysis of the optical EPR experiment performed by Weihs et al in Innsbruck 1997-1998. Under the commonly used assumption of fair sampling, we show that the coincidence counts exhibit a small and anomalous non-signalling component, which seems impossible to explain by using the conventional quantum mechanics, and we discuss some possible interpretations of this phenomenon.

    Is the fair sampling assumption supported by EPR experiments?2007In: Journal of Physics B: At. Mol. Opt. Phys., ISSN 0953-4075, Vol. 40, no 1, p. 131-141Article in journal (Refereed)
    Abstract [en]

    We analyse optical EPR experimental data performed by Weihs et al in Innsbruck 1997–1998. We show that for some linear combinations of the raw coincidence rates, the experimental results display some anomalous behaviour that a more general source state (like non-maximally entangled state) cannot straightforwardly account for. We attempt to explain these anomalies by taking account of the relative efficiencies of the four channels. For this purpose, we use the fair sampling assumption, and assume explicitly that the detection efficiencies for the pairs of entangled photons can be written as a product of the two corresponding detection efficiencies for the single photons. We show that this explicit use of fair sampling cannot be maintained to be a reasonable assumption as it leads to an apparent violation of the no-signalling principle.

    Test of the no-signaling principle in the Hensen loophole-free CHSH experiment2017In: Fortschritte der Physik, ISSN 0015-8208, E-ISSN 1521-3978, Vol. 65, no 9, article id 1600096Article in journal (Refereed)
    Abstract [en]

    We analyze the data from the loophole-free CHSH experiment performed by Hensen et al., and show that it is actually not exempt of an important loophole. By increasing the size of the sample of event-ready detections, one can exhibit in the experimental data a violation of the no-signaling principle with a statistical significance at least similar to that of the reported violation of the CHSH inequality, if not stronger. The data from the loophole-free CHSH experiment performed by Hensen et al. are analysed, It is shown that it is actually not exempt of an important loophole. By increasing the size of the sample of event-ready detections, one can exhibit in the experimental data a violation of the no-signaling principle with a statistical significance at least similar to that of the reported violation of the CHSH inequality, if not stronger.

    Double Blinding-Attack on Entanglement-Based Quantum Key Distribution Protocols2012In: AIP Conference Proceedings, ISSN 0094-243X, E-ISSN 1551-7616, Vol. 1424, no 1, p. 9-16Article in journal (Refereed)
    Abstract [en]

    We propose a double blinding-attack on entangled-based quantum key distribution protocols. The principle of the attack is the same as in existing blinding attack except that instead of blinding the detectors on one side only, Eve is blinding the detectors of both Alice and Bob. In the BBM92 protocol, the attack allows Eve to get a full knowledge of the key and remain undetected even if Alice and Bob are using 100% efficient detectors. The attack can be easily extended to Ekert protocol, with an efficiency as high as 85.3%.

    Multiple-photon absorption attack on entanglement-based quantum key distribution protocols2013In: Quantum Bio-Informatics V: Proceedings of the Quantum Bio-Informatics 2011 : Tokyo University of Science, Japan, 7 – 12 March 2011 / [ed] Luigi Accardi, Wolfgang Freudenberg, Masanori Ohya, Singapore: World Scientific, 2013, vol. 30, p. 171-180Conference paper (Refereed)
    Abstract [en]

    We propose a multiple-photon absorption attack on Quantum Key Distribution protocols. In this attack, the eavesdropper (Eve) is in control of the source and sends pulses correlated in polarization (but not entangled) containing several photons at frequencies for which only multiple-photon absorptions are possible in Alice's and Bob's detectors. Whenever the number of photons from one pulse are dispatched in insufficient number to trigger a multiple-photon absorption in either channel, the pulse remains undetected. We show that this simple feature is enough to reproduce the type of statistics on the detected pulses that are considered as indicating a secure quantum key distribution in entangled-based protocols, even though the source is controlled by Eve, and we discuss possible countermeasures.

    Abstract [sv]

    Äktenskapet står starkt som juridiskt skydd i Sverige, samtidigt som man fokuserar på jämställdhet och allas lika värde. Kungahuset ordnar bröllop med jämlik aura. Har kritiken av äktenskapet glömts bort?

    Inte den typ som gifter sig?: Feministiska samtal om äktenskapsmotstånd2008Doctoral thesis, monograph (Other academic)
    Abstract [en]

    Den här avhandlingen undersöker frågan om äktenskapsmotstånd i dagens svenska samhälle, media och kultur. Boken belyser olika sätt att uttrycka äktenskapsmotstånd och vad det betyder att formulera feministisk kritik av normerande familjevärderingar.

    Undersökningen baseras på etnografi och kritisk kulturanalys och granskar synen på äktenskap, relationer och familj som ett kulturellt imaginärt fält. Det empiriska materialet består av intervjuer med kvinnor som inte har velat gifta sig, liksom ett brett material från tv, webbsidor, dagstidningar, skvallerpress och bloggar.

    I avhandlingen genomförs och presenteras en feministisk metodologisk process, grundat i akademiskt kreativt och självreflexivt skrivande. Detta innebär att skrivprocessen, textformatet, liksom minnesarbete, olika intervjutekniker och andra kreativa analytiska praktiker är en del av det metodologiska ramverket.

    De teoretiska perspektiven som ligger till grund för denna studie består av flera feministiska strömningar: radikalfeminism, queerfeminism, liberealfeminism, anarkafeminism och ett socialt rättviseperspektiv. De belyser, på olika sätt, intersektioner mellan äktenskap, genus, sexualitet, nationalitet, klass och makt. En gemensam utgångspunkt är att identitetskategorier, möjligheter att agera liksom vår plats i världen är konstruerade av maktrelationer och normativa föreställningar om genus. Dessa perspektiv tillhandahåller analytiska verktyg för att diskutera och dekonstruera kulturella föreställningar om äktenskap och äktenskapsmotstånd.

    Abstract [sv]

     Artikeln handlar om skvallerpressens representation av celebriteterna Brad Pitt och Angelina Jolie, och hur deras icke-gifta status producerar moralpanik och genusproblem i den populärkulturella heteronormativiteten. Artikeln tar också upp "äktenskapsfrågan" i en svensk kontext och hur frågan om äktenskapsmotstånd glömts bort av feminismen.

    Electronic Health Record Systems: A study of privacy in the region Kronoberg of Sweden2016Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    This study gives a brief description of paper-based record and the adoption of ICT, which brought the introduction of Electronic Health Record System (EHRS) in Sweden, the challenges facing EHR in the health care sector around the world and what immigrants and newcomers who just arrived in Sweden knows about the privacy,  rights and the policies that protect their privacy and data system, these could cause them not having enough confidence in electronic health record system, they could also be worried about their information been exposed or disclosed by their healthcare providers, this call for the confidentiality, security and privacy of EHR System. The aim of this study is to explore immigrants and newcomers as users of electronic health record system by setting interview questions and focus group to help the researcher to understand their knowledge of what they know about the privacy of EHRS and what they know about the policies health care providers follow to protect patient’s privacy and data. It is very important for them to know their rights and the rights that protect their privacy and data from been shared or disclosed.

     

    The study also talked about the existing implications facing EHRs, comparison of both systems was shown in table 1 of this study. The necessity for a proper protection of patient data was discussed and recommendation was made towards having a great and a working electronic health record system.

    Abstract [en]

    A challenge when interpreting prehistoric art is that we often lack written source material, a contemporary text written by people who lived in the cultural context that is studied. It is therefore not uncommon to use texts that are younger than the material that we want to interpret. This could lead to misinterpretations and circular arguments. Images are cultural products formed by their contemporaries and influenced by older idea traditions. This article presents four criteria that might be worth taking into consideration when interpreting prehistoric religious iconography. The article discusses how one might proceed to study prehistoric religious art and what could be helpful to keep in mind when analyzing religions by means of pictures and material culture.

    Abstract [en]

    This article discusses the difference between identifying and classifying attributes and analyzes the problematic implications if we confuse the two. The empirical material consists of Gallic stone reliefs depicting goddesses with a wheel as attribute. Male deities depicted with wheels have mainly been identified as a Celtic Jupiter or a male sky god sometimes called Taranis. The Gallic goddesses show that the wheel attribute was not an identifying attribute exclusive to this god, but that it rather served as a marker for an activity shared by several deities, both male and female. The articles argument that we need to distinguish between identifying and classifying attributes in order to make a source critical and methodological correct iconographical interpretation, especially when we interpret iconographical representation without the aid of any written sources.
