    Narrative teacher identities in preschool class: Stories from a borderland2008In: ECER 2008, From Teaching to Learning?, 2008Conference paper (Refereed)
    Abstract [en]

    Aims & methodA new arena, the preschool class, is arising between preschool and compulsory school. One can assume that new teacher identities are formed in this new borderland. This study, which is in its introduction phase, aims to search for answers about how the teachers chose to describe themselves as teachers in preschool class, how they are talking about themselves, who they are today and who they want to be tomorrow. In other words, which teacher identities these variations contain.

    In the study the teacher identities will be investigated by their narratives in interaction with and between teachers in focus groups. Bruners (1986) starting point is that narratives creates and recreates relations and identities, and that narrative telling can be seen as an act of reality making.  The narratives render possible definitions of identities in the social life.

    The identities the teachers in preschool class assume is not static, instead they can change constantly on the basis of experiences and reflections. The identities constitute a part of the teachers aims to create meaning in their actions in the pedagogical practice, both historical, current and according to their goals for the future (Beijaard m.fl., 2004; Geijsel & Meijers, 2005). In the study the teacher identities are connected to their actions in the pedagogical practice (ex. Irisdotter, 2006; Beijaard, Meijer, & Verloop, 2004 & Säljö, 2000).

    The theoretical perspectives in the studyThe study is built on sociocultural theories, social constructionism and border theories. In sociocultural theories meaning making can be seen as mediated through language, where our meaning making processes can be seen as reactions on cultural, historical and social circumstances and where we create ourselves in a narrative praxis (ex. Bruner, 1990 & Rogoff, 2003).

    The preschool class can be considered as a borderland between preschool and compulsory school, hence border theories can be productive in a study of teachers in preschool class. We all live in a world, where (invisible) borders control our lives. Frontiers, borders and borderlands used in geographical literature have a big relevance on our lives and social interactions. The borders creates transition zones to which people from both sides of the border are given permission and where hybrid groups with hybrid identities permits to grow (Newman, 2003). The individual narratives and identities are changing when an activity is transferred to a new territory. Thereby, when individuals are moving from one category or area to another they can experience a form of transition hybridity, where they has assimilated “the new” at the same time as they sustain a great part of  “the old” (Newman, 2006b).

    The contribution from the social constructionism to this study is the starting point that teacher identities can’t be found passively inside the teacher, instead the teacher identity is created in a social act and in a specific practice.  Hence, the focus in this study is on what happens in the relations between people, and what is communicated and expressed in this communication (Shotter, 2005).

    MethodsFocus groups are used as the research method. Approximately 15 teachers working in preschool class are participating, and they are divided into three focus groups. Each group is gathered three times, and each time a main theme for discussion is presented from me as the researcher and moderator of the groups. Data is produced via interaction between the teachers and their narratives are recorded by audio technique. The narratives are then analyzed with focus on the content in the discussions and with the aim to make the variation of the teacher’s identities in preschool class visible. 

    Expected outcomesThis study can make a contribution to the research on professional identities in general and teachers’ professional identities in particular. It has the potential to generate new hypothesis about the construction of “teachers”. Firstly by focusing on a “new” teacher profession, and secondly by connecting border theories to research on professional identities.

    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.

    Sustainable Development in Swedish Municipalities: To know, to be able, to want and to do2001Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    A process of change like the building-up of sustainable societies can be visualised as four steps: to know, to be able, to want and to do. To pay attention to the appropriate measures and the best solutions implies a wide range of knowledge of natural and societal conditions. But to make it possible to realize them, there has to be space of action including physical tools (technique, money etc.), as well as desire and courage among the participants and decision-makers to act towards sustainability. The most important prerequisites for sustainable development are considered to be appropriate natural resources management and public participation. In this thesis I concentrate on the possibilities of modifying administration at local levels in order to economise resources in durable ways, locally as well as globally. In some case studies I examine to what extent local Agenda 21 (LA21) processes can facilitate this realization.

    In developing more sustainable societies I emphasise the following aspects to be among the most relevant: Society has to prepare for unexpected outcomes, thus the apparent unpredictability of the behaviour of ecosystems and their response to impacts have to be taken into account in planning and in making decisions. Moreover, it has to be discussed what to do if aims are reached without obtaining the expected recovery in the ecosystems and in the natural situation. Environmental space and function should more often be used as a basis when managing natural resource. Finally, the interplay beween the central and the local levels should be enhanced in order to choose the most relevant measures and to strive in the same direction: towards creating more flexible societies.

    The LA21 processes can very well be excellent tools in this work because they provide platforms for better understanding and exchange of knowledge and experience among different levels of society. These discussions can make the participants more willing to take actions as well as to find new solutions and new ways acting.

    The case studies show that the first steps towards more sustainable societies are taken. The support for LA21 given by the local governments has been and is absolutely vital to the progress and results of the processes. The most progressive results are found in the municipalities of the case study where top-level politicians have been most interested and have taken on the responsibility of LA21. My main conclusions of how the LA21 processes and the striving towards sustainability could be improved are that goals and visions should be discussed more thoroughly involving many parts of society. More and more these visions and objectives should observe the connections between environmental, economic and social issues. Furthermore, measures and actions should be diversified and flexible, and co-operation across administrative borders should be developed. It is also essential to formulate strategies of how to deal with up-coming ideas and proposals as well as how to increase the level of influence of all participants. In order to improve the handling of natural resources the kind of resource and the functions making it one has to be identified. To choose the most appropriate measures it is important to know if the resource is vital and scarce, scarce, or poisonous and/or if its use may cause pollution.

    Paper I comprises the frame of and the tools for developing the local system in Sweden in the direction of global sustainability. Swedish municipalities have taken the first steps towards sustainability mainly through local Agenda 21 processes. Environmental issues have a prominent role in the decision-making of the local governments, but social and economic topics are not connected to decisions on sustainable development to the same extent. How to proceed at the local level is discussed in this paper as is the national frame and local prerequisities for achieving sustainable development. This article states that most important factors, when creating sustainable societies, are active, high-level politicians and officials, a structured process with co-operation aiming at including all stakeholders' real influence, increased knowledge among all participants, positive thinking, feedback and information, money and much time. To use limited projects as one of the first steps of a more comprehensive process may attract more inhabitants to take part. Their results can be shown quite rapidly, further encouraging actions and involvement in other areas of interest.

    The papers II and III are based on a five-year study of the LA21 processes in four Swedish municipalities. In Paper II the LA21 of two of the chosen municipalities are analysed. Comparisons between attitudes among local politicians and officials and LA21 documents and projects indicate that the most important issues, to protect clean air and to co-operate with the inhabitants in LA21, are followed up in plans, actions and projects connected to LA21. The local governments have made efforts to improve the natural resources management, to prolong the views of planning in the local government, but they have difficulties in interpreting visions and long-term goals in their daily decisions. It is still too early to discern whether or not the two municipalities have moved towards sustainability.

    Paper III includes results from all four municipalities. This study shows that the LA21 processes have aroused many new thoughts, brought fields together and introduced new subjects into the municipal world. In the decisions of the local govemments' environmental considerations are treated seriously. There are signs of an increased dialogue and of public influence, especially within fields where the inhabitants are users. It is indicated that LA21 does not seem to have great influence on which natural resources are dealt with, but on how. New stakeholders within and outside the municipal organization have been identified through the LA21 processes, and more comprehensive ways of solving problems and a positive climate of testing new ideas have been created. In these respects LA21 has been and will be a significant support to the development of appropriate natural resources management at the local level.

    In Paper IV a part of a local Agenda 21 project aiming at reducing the nutrient supply into a Swedish Baltic Sea fjord is analysed. The reduction is to be carried out in way that permits and facilitates the re-use of the nutrients as fertilizers. This article is focused on how to implement the project and on how to increase public participation, especially that of farmers and owners of houses of single sewage treatment systems. Increased public participation needs continuous efforts by the project leaders. Indivdual as well as group actions, forming of small groups, information, feedback and continous encouragement are crucial. The homogenous group of farmers considers the management of natural resources very important. They have voluntarily formed five watercourse groups where community management is developed. The owners of houses of single sewage treatment systems form a heterogeneous group. They are mostly interested in individual measures. Constant changes of the prerequisites of sewage systems and lack of knowledge are other obstacles against carrying out voluntary measure.

    Resursskolan: Före detta elevers upplevelser av hemskola, särskiljande och resursskola2008Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpStudent thesis
    Abstract [en]

    The purpose of this study was to investigate how former pupils in a daycareschool experienced there stay, in relation to the ordinary school. The method we used was an qualitative interview study with former pupils of a daycareschool. We have analyzed the result with help of Goffmans theory about stigma, Beckers labeling theory, Antonovskys SOC (a Sense Of Coherence) concept and Gjaerums theory of controlling. After analyzing the results we came to the conclution that the pupils where stigmatized and labeled as deviants in the ordinary school whilst in the daycareschool they got an enhanced SOC and a feeling of control. Due to the daycareschool’s work with these pupils they no longer sees as stigmatized and labeled.

    Go Green in the Automotive Industry: Open and Networked Innovation applied by Tesla Motors and Renault2008Independent thesis Advanced level (degree of Magister), 20 poäng / 30 hpStudent thesis
    Abstract [en]

    In today’s economical world, companies realize the importance to build corporate strategies on innovation to sustain a continuous profitability. Innovation is a crucial issue to develop a competitive advantage. In our networked economy, companies can not only rely on in-house activities anymore to raise creative and come up with breakthrough innovations they need to collaborate with actors from the external environment. Firms have to think outside their own boundaries to leverage the complementary resources and capabilities needed to innovate. Partnerships help to ensure firms’ future successes.

    The purpose of our study is to understand how companies, operating in the automotive industry, integrate ‘Open and Networked Innovation’ concepts in their corporate strategy to enhance their environmental friendly profile. As far as the EV market is concerned, our study will also lead to determine the Key Factors of Success and the barriers that companies have to face when they want to launch an electric car in the market.

    Various theoretical approaches have been developed over the time about Open Innovation and Networked Innovation. The dilemma of paradoxical organization needs of radical innovation, exposed by Dr Sigvald Harryson, is our theoretical starting-point to analyze company’s ability to find the right equilibrium between exploration and exploitation and absorptive capacity. Further on, we explore the question of absorptive capacity to know how firms identify, acquire, transfer and transform knowledge.

    Thereafter, the theoretical framework is confronted with empirical data based on a qualitative and abductive approach of two case studies – Tesla and Renault. Interviews with Tesla, located in the Silicon Valley, California, USA, have been conducted. We also met two key employees in Renault’s headquarter, Paris, France. Interpretation and explanation of the data collected is reported in our analysis of each case as well as in the cross-case analysis. A presentation of our recommendations and conclusions conclude our master thesis.

    Den nya Arenan: Dansband eller Rock 'n Roll för Kalmar som destination?2010Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Syftet med den här uppsatsen är att studera om den nya Arenan kan komma att vara en bidragande faktor till säsongsförlängning i Kalmar. Eftersom den nya Arenan inte ännu är färdigbyggd, vill vi undersöka beslutsfattares syn på projektet samt hur ett sådant projekt kan komma att påverka Kalmar som destination.

    För att kunna studera verkligheten, utan att styras av redan befintliga teorier, valde vi i vår studie att använda oss av en induktiv ansats. Den större delen av vår datainsamling grundas på kvalitativa intervjuer, vilka vi kompletterade med diverse rapporter och skrivelser på hemsidor.

    Vår slutsats i den här uppsatsen är att den nya Arenan kan bidra till säsongsförlängning om verksamheten maxas. För att detta ska vara möjligt bör samtliga beslutsfattare börja spela i samma lag, klara och tydliga mål med projektet måste sättas upp och fokus bör läggas på hur ett projekt av den här storleken kan gynna hela Kalmar som destination, inte enbart en av de inblandade aktörerna.

    Temporal Distance and Moral Concerns: Future Morally Questionable Behavior is Perceived as More Wrong and Evokes Stronger Prosocial Intentions2009In: Basic and Applied Social Psychology, ISSN 0197-3533, E-ISSN 1532-4834, Vol. 31, no 1, p. 49-59Article in journal (Refereed)
    Abstract [en]

    Prior research on temporal construal has shown that core values become more salient when people think about distant- as compared to near-future events. The present research shows that greater temporal distance of an event also results in greater moral concern. More specifically, it was found that people make harsher moral judgments of others' distant-future morally questionable behavior than near-future morally questionable behavior. Moreover, it was shown that people increasingly attribute distant vs. near future behavior to abstract dispositional relative to concrete situational causes, and that this attribution bias is partially responsible for the temporal distance effect on moral judgments.

    Moral reasoning:: The influence of affective personality, dilemma content and gender2006In: Social behavior and personality, ISSN 0301-2212, E-ISSN 1179-6391, Vol. 34, no 10, p. 1259-1276Article in journal (Refereed)
    Abstract [en]

    This study examined the influence of affective personality, perfectionism, gender, arousal and dilemma content on moral reasoning. 264 participants were presented with moral dilemmas to which they had to provide a solution that reflected various degrees of justice and care. The results indicated that a) affective personality had an effect on moral reasoning, b) female participants reported higher levels of care morality than did male participants, c) gender interacted with perfectionism in the production of moral standpoints, d) dilemma content exerted a strong effect on the participants' use of moral strategy. It was concluded that although moral reasoning appears to be governed primarily by the dilemma content at hand, an individual's moral solutions are influenced by gender and affective state.

    Virtuella rese-communities: deras roll ur ett relationsorienterat marknadsperspektiv2008Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpStudent thesis
    Abstract [sv]

    Bakgrund/Problem: Hur kan ett rese-community gynna ett företags långsiktiga relation till sina kunder?

    Syftet med uppsatsen är att analysera och skapa förståelse för vilken roll och funktion rese-communities spelar ur ett relations-orienterat marknadsföringsperspektiv.

    Denna undersöknings uppläggning baseras helt på det problem som definierats samt det syfte i vilket undersökningen bedrivs. I denna uppsats har jag valt att använda mig av såväl en deskriptiv som explorativ undersökningsstrategi. Jag har också använt mig av en kombination av deduktiv och induktiv ansats, då jag anser att undersökningen präglas av en abduktivt ansats. Det metodologiska tillvägagångssättet har varit kvalitativt. Den insamlade empirin insamlades genom djupgående intervjuer med 7 specialister från olika företag som uppmärksammat fördelarna med driften av resecommunities. Intervjuerna präglades av mitt val av en kvalitativ metodval jag hela tiden eftersträvade en närhet till mina respondenter.

    Då denna uppsats är av kvalitativ art och undersökningens syfte snarare är att analysera och skapa förståelse än att komma fram till några absoluta sanningar tillåts jag inte göra några generaliseringar. Jag har dock valt att ändå försöka presentera några uppmärksammade mönster och egna tankar kring ämnet; resecommunities. De analyser jag gör presenteras i empiri och analys kapitlet där den insamlade empirin presenteras i anslutning till kommentarer från de teoretiska referensramarna. De begrepp jag har valt att fokusera på är de som uppkom vid min problemdiskussion, mina delproblem som berör begreppen; värde, lojalitet, engagemang och varumärke. De intressanta tendenser och mönster som jag kommit fram till presenteras i mitt avslutande kapitel; slutsats & diskussioner där jag även framför mina egna tankar och åsikter kring undersökningen och ämnet; rese-communities.

    Microsoft Windows Server 2008 Terminal Services vs. Citrix XenApp2008Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Den här rapporten undersöker om gränsen mellan Terminal Services och Citrix XenApp har börjat suddas ut eller om man ännu kan dra en tydlig linje mellan dessa. Detta för att avgöra om organisationer som idag kör Windows Server 2003 med Citrix XenApp enbart klarar sig med de nya funktionerna i Windows Server 2008 Terminal Services och ändå uppfylla de krav och behov en organisation har. Arbetet genomfördes rent teoretiskt. För att avgöra likheter och skillnader mellan applikationerna, så användes till största delen ett ramverk. För att kunna få en bild av hur applikationerna tillämpas rent praktiskt, användes tidigare testar samt analyser. Resultatet visar att Terminal Services tagit ett större steg inom marknaden för applikationsvirtualisering. Slutsatsen antyder att Windows Server 2008 Terminal Services är lämplig för organisationer utan komplexa behov.

    Abstract [sv]

    Syftet med vår studie är att undersöka lärare och elever i grundskolans tidigare års upplevelse av självbildens betydelse för motivation, lärande och lärmiljö. Vi har använt oss av intervjuer som undersökningsinstrument samt framställt observationsskisser av olika klassrum. Intervjuerna genomfördes med elever i årskurs 1 och 2 och med klasslärare i årskurs 1 och 2. Klassrumsobservationerna genomfördes i respektive klasslärares hemklassrum. Totalt intervjuade vi fyra klasslärare samt 23 elever. 

    Resultatet visar att de intervjuade lärarna är eniga om att självbilden har stor inverkan på både lärande och motivation. För att hålla motivationen vid liv krävs en positiv självbild. Även tryggheten i gruppen har en betydande roll i skapandet av en positiv självbild. Elever med mindre bra självbild placeras ofta strategiskt långt fram i klassrummet så att läraren ska kunna stödja och uppmuntra dessa elever. Vidare framhåller lärarna att elevernas tro på den egna förmågan krävs för lärande och personlig utveckling. Som lärare har man en oerhört viktig roll i att motivera och engagera eleverna. Lärarna och eleverna uttrycker liknande resonemang om behovet av fler och större utrymmen att tillgå i undervisningen. Lärarna och majoriteten av eleverna har även liknande resonemang kring placering i klassrummet för bästa koncentration, två och två placering anses ge bäst arbetsklimat. Resultatet visar vidare att eleverna överlag trivs bra i sina respektive lärmiljöer och vågar uttrycka sina åsikter. De antyder även att de känner sig sedda och får stöd och hjälp i undervisningen. Koncentration är något som genomsyrar elevernas tankar kring lärande.

    Intervjuade lärare ser självbilden som viktig för motivation och lärande. Trygghet och trivsel i lärmiljön är en grund för positiv lärmiljö enligt både lärare och elever. Även samspelet mellan både elever och lärare har en betydande roll i elevens utveckling och lärande. Samband mellan otrygghet och mindre bra självbild visar sig hos vissa av de intervjuade eleverna. Hos resterande elever visar sig istället samband mellan känsla av trygghet och positiv självbild.

    Evenemang: -ett vinnande koncept för regional utveckling?2001Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Event is a phenomenon that lately has become more common, especially within the tourism industry. This essay is a study within human geography and with focus on the meaning and the design of events. The purpose with this essay is to examine and describe the concept of event and to show how events can influence a region. Falkenberg is situated in the county of Halland by the west coast and the sea and because of that a natural tourist destination. The city is a known seaside resort since the end of the nineteenth century. Our method is a case study with interviews with seven of the participants active within events in Falkenberg.

     

    This essay shows that events are limited in time and space, they have their own attraction and uniqueness and it all sums up into what the visitor expects to experience and what they will experience. An event is a business opportunity, and it increases the flow of visitors and money through the region. The image of the region can be influenced by events and in the long run lead to a brand that enhances the regions values.

    Gasens inverkan på oljan i ett hydrauliksystem2009Independent thesis Basic level (degree of Bachelor), 5 credits / 7,5 HE creditsStudent thesis
    Abstract [en]

    I detta arbete har vi med en litteraturstudie försökt påvisa vad en inblandad gas i oljan i ett hydrauliksystem har för betydelse för funktionen. Vi har använt information i traditionell facklitteratur samt i tidskrifter och vetenskapliga rapporter och upptäckt att problemen som uppkommer av inblandade gaser inte är väl kända. Dagens lösningar på problemen är nästan alltid kostsamma och handlar om att behandla symptomen. Vi har tittat på de olika fysikaliska data som gasen inverkar på i oljan, utifrån detta har vi analyserat vilka effekter detta har för ett hydrauliksystems funktion. Vi kommer att diskutera grundproblemet till kavitation och vanliga problem som ett hydrauliksystem ofta har. Vi har lyckats presentera resultat på att inblandad gas i oljan har en mycket stor inverkan på ett hydrauliksystem. Vi har kommit fram till att mycket av dagens problem med hydrauliksystem helt skulle kunna byggas bort om man tog större hänsyn till oljans förmåga att lösa in luft.

    Regioner utan gränser: En studie om hur mindre svenska tjänsteföretag drar nytta av sin region för att locka en internationell kundkrets2009Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syftet med uppsatsen var att beskriva hur mindre tjänsteföretag drar nytta av sin region för att locka internationella gäster. Analysera hur de använder sig av platsmarknadsföring och samverkan samt ge rekommendationer till liknande företag.

    Vi har använt oss utav en abduktiv ansats samt ett kvalitativt forskningsangreppssätt. De organisationer som vi studerat och intervjuat är Mundekulla, Astrid Lindgrens Värld, Hotell Ronja samt Regionförbundet.

    Vi har använt oss av källor som kan hjälpa oss skapa en teoretisk syntes kring våra delfrågor inom ämnena: Tjänsteföretagens internationalisering och marknadsföring, Hur regioner och företag samverkar samt Hur regioner arbetar med platsmarknadsföring.

    Vi har kommit fram till att regional samverkan är av stor vikt när ett mindre tjänsteföretag ska locka en internationell kundkrets. Samverkan sker på olika nivåer.

    External Knowledge Acquisition And Transfer From Innovation Clusters To Central R&D Unit: The Mediating Role Of R&D Listening Posts As Technological Gatekeepers2009Independent thesis Advanced level (degree of Master (One Year)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Over the last few decades, the industrialized world in general and the automobile industry in particular was hit by immense changes which strongly influence the management of R&D. Trends such as globalization and sharp competition on worldwide open markets, increasing product complexity in order to meet the customers’ desires for more variety and individualization, technology fusion and cross industry innovations, high level of technological and competitive uncertainty, increasing pressure to reduce R&D budgets, and shorter time to market and reduced innovation cycles in consequence of rising competition, force companies to source external knowledge and to bring in and exploit outside-in innovations instead of reinventing them their selves. In the same way, the Open Innovation concept highlights the need for organizations to open up their innovation processes. As a consequence, many R&D organizations are being transformed in order to meet the upcoming challenges and established technological listening posts to source external knowledge in centers of technological excellence and innovation.

    This study focus on the knowledge acquisition, transformation and transfer from innovation cluster to central R&D, and examines the roles and typologies of technological gatekeepers. Based on a sound literature review and in-depth qualitative study of the case company BMW, this thesis explores how technological listening posts can take the mediating role of technology gatekeepers and how different mechanisms and typologies for gatekeeping can be deployed for optimal transformation and transfer of external knowledge into internal innovation.

    Measurement of the cosmic ray composition at the knee with the SPASE-2/AMANDA-B10 detectors2004In: Astroparticle physics, ISSN 0927-6505, E-ISSN 1873-2852, Vol. 21, no 6, p. 565-581Article in journal (Refereed)
    Abstract [en]

    The mass composition of high-energy cosmic rays at energies above 1015 eV can provide crucial information for the understanding of their origin. Air showers were measured simultaneously with the SPASE-2 air shower array and the AMANDA-B10 Cherenkov telescope at the South Pole. This combination has the advantage to sample almost all high-energy shower muons and is thus a new approach to the determination of the cosmic ray composition. The change in the cosmic ray mass composition was measured versus existing data from direct measurements at low energies. Our data show an increase of the mean log atomic mass 〈lnA〉 by about 0.8 between 500 TeV and 5 PeV. This trend of an increasing mass through the "knee" region is robust against a variety of systematic effects. © 2004 Elsevier B.V. All rights reserved.

    Observation of high energy atmospheric neutrinos with the Antarctic muon and neutrino detector array2002In: Physical Review D, ISSN 1550-7998, E-ISSN 1550-2368, Vol. 66, no 1, p. 120051-1200520Article in journal (Refereed)
    Abstract [en]

    The Antarctic muon and neutrino detector array (AMANDA) began collecting data with ten strings in 1997. Results from the first year of operation are presented. Neutrinos coming through the Earth from the Northern Hemisphere are identified by secondary muons moving upward through the array. Cosmic rays in the atmosphere generate a background of downward moving muons, which are about 106 times more abundant than the upward moving muons. Over 130 days of exposure, we observed a total of about 300 neutrino events. In the same period, a background of 1.05 × 109 cosmic ray muon events was recorded. The observed neutrino flux is consistent with atmospheric neutrino predictions. Monte Carlo simulations indicate that 90% of these events lie in the energy range 66 GeV to 3.4 TeV. The observation of atmospheric neutrinos consistent with expectations establishes AMANDA-B10 as a working neutrino telescope.

    Limits to the muon flux from WIMP annihilation in the center of the Earth with the AMANDA detector2002In: Physical Review D, ISSN 1550-7998, E-ISSN 1550-2368, Vol. 66, no 3, p. 032006-Article in journal (Refereed)
    Abstract [en]

    A search for nearly vertical up-going muon-neutrinos from neutralino annihilations in the center of the Earth has been performed with the AMANDA-B10 neutrino detector. The data collected in 130.1 days of live time in 1997, ∼10 9 events, have been analyzed for this search. No excess over the expected atmospheric neutrino background has been observed. An upper limit at 90% confidence level has been obtained on the annihilation rate of neutralinos in the center of the Earth, as well as the corresponding muon flux limit, both as a function of the neutralino mass in the range 100 GeV-5000 GeV. © 2002 The American Physical Society.

    Search for point sources of high-energy neutrinos with AMANDA2003In: Astrophysical Journal Letters, ISSN 2041-8205, Vol. 583, no 2 I, p. 1040-1057Article in journal (Refereed)
    Abstract [en]

    This paper describes the search for astronomical sources of high-energy neutrinos using the AMANDA-B10 detector, an array of 302 photomultiplier tubes used for the detection of Cerenkov light from upward-traveling neutrino-induced muons, buried deep in ice at the South Pole. The absolute pointing accuracy and angular resolution were studied by using coincident events between the AMANDA detector and two independent telescopes on the surface, the GASP air Cerenkov telescope and the SPASE extensive air shower array. Using data collected from 1997 April to October (130.1 days of live time), a general survey of the northern hemisphere revealed no statistically significant excess of events from any direction. The sensitivity for a flux of muon neutrinos is based on the effective detection area for through-going muons. Averaged over the northern sky, the effective detection area exceeds 10,000 m2 for E μ ≈ 10 TeV. Neutrinos generated in the atmosphere by cosmic-ray interactions were used to verify the predicted performance of the detector. For a source with a differential energy spectrum proportional to Eν -2 and declination larger than +40°, we obtain E2(dNν/dE) ≤ 10-6 GeV cm-2 s-1 for an energy threshold of 10 GeV.

    Search for neutrino-induced cascades with the AMANDA detector2003In: Physical Review D, ISSN 1550-7998, E-ISSN 1550-2368, Vol. 67, no 1, p. 012003-Article in journal (Refereed)
    Abstract [en]

    We report on a search for electromagnetic and/or hadronic showers (cascades) induced by a diffuse flux of neutrinos with energies between 5 TeV and 300 TeV from extraterrestrial sources. Cascades may be produced by matter interactions of all flavors of neutrinos, and contained cascades have better energy resolution and afford better background rejection than throughgoing νμ-induced muons. Data taken in 1997 with the AMANDA detector were searched for events with a high-energy cascadelike signature. The observed events are consistent with expected backgrounds from atmospheric neutrinos and catastrophic energy losses from atmospheric muons. Effective volumes for all flavors of neutrinos, which allow the calculation of limits for any neutrino flux model, are presented. The limit on cascades from a diffuse flux of νe+ νμ + ντ+ ν̄e + ν̄μ+ ν̄τ is E2(dΦ/dE)<9.8×10-6 GeV cm-2 s-1 sr-1, assuming a neutrino flavor flux ratio of 1:1:1 at the detector. The limit on cascades from a diffuse flux of νe+ν̄e is E2(dΦ/dE)<6. 5×10-6 GeV cm-2 s-1 sr-1, independent of the assumed neutrino flavor flux ratio. © 2003 The American Physical Society.

    Search for supernova neutrino bursts with the AMANDA detector2001In: Astroparticle physics, ISSN 0927-6505, E-ISSN 1873-2852, Vol. 16, no 4, p. 345-359Article in journal (Refereed)
    Abstract [en]

    The core collapse of a massive star in the Milky Way will produce a neutrino burst, intense enough to be detected by existing underground detectors. The AMANDA neutrino telescope located deep in the South Pole ice can detect MeV neutrinos by a collective rate increase in all photo-multipliers on top of dark noise. The main source of light comes from positrons produced in the CC reaction of anti-electron neutrinos on free protons ve + p → e+ + n. This paper describes the first supernova search performed on the full sets of data taken during 1997 and 1998 (215 days of live time) with 302 of the detector's optical modules. No candidate events resulted from this search. The performance of the detector is calculated, yielding a 70% coverage of the galaxy with one background fake per year with 90% efficiency for the detector configuration under study. An upper limit at the 90% c.l. on the rate of stellar collapses in the Milky Way is derived, yielding 4.3 events per year. A trigger algorithm is presented and its performance estimated. Possible improvements of the detector hardware are reviewed.

    Calibration and survey of AMANDA with the SPASE detectors2004In: Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, ISSN 0168-9002, E-ISSN 1872-9576, Vol. 522, no 3, p. 347-359Article in journal (Refereed)
    Abstract [en]

    We report on the analysis of air showers observed in coincidence by the Antarctic Muon and Neutrino detector array (AMANDA-B10) and the South Pole Air Shower Experiment (SPASE-1 and SPASE-2). We discuss the use of coincident events for calibration and survey of the deep AMANDA detector as well as the response of AMANDA to muon bundles. This analysis uses data taken during 1997 when both SPASE-1 and SPASE-2 were in operation to provide a stereo view of AMANDA. © 2003 Elsevier B.V. All rights reserved.

    Limits on diffuse fluxes of high energy extraterrestrial neutrinos with the AMANDA-B10 detector2003In: Physical Review Letters, ISSN 0031-9007, E-ISSN 1079-7114, Vol. 90, no 25, p. 2511011-2511015Article in journal (Refereed)
    Abstract [en]

    A report on the limits, which could be placed on diffuse fluxes of high energy extraterrestrial neutrinos, was presented. The incorporation of neutrino oscillations was necessary for interpreting the limits in terms of the flux from a cosmological distributions of sources. The energetic accelerated environments were presented as the sources of high energy extraterrestrial neutrinos.

    Search for Extraterrestrial Point Sources of Neutrinos with AMANDA-II2004In: Physical Review Letters, ISSN 0031-9007, E-ISSN 1079-7114, Vol. 92, no 7, p. 711021-711025Article in journal (Refereed)
    Abstract [en]

    The results of a search for point sources of high energy neutrinos in the northern hemisphere were presented using AMANDA-II data collected in the year 2000. The results included the flux limits on several active-galactic-nuclei blazars, microquasars, magnetars, and other candidate neutrino sources. A search for excesses above a random background of cosmic ray induced atmospheric neutrinos and misreconstructed downgoing cosmic-rays muons, which revealed no statistically significant neutrino point sources was also presented. It was shown that AMANDA-II had achieved the sensitivity required to probe known TeV γ-ray sources such as the blazar Markarian 501 in its 1997 flaring state at a level where neutrino and γ-ray fluxes were equal.

    Results from the Antarctic muon and nuetrino detector array2003In: Nuclear physics B, Proceedings supplements, ISSN 0920-5632, E-ISSN 1873-3832, Vol. 118, p. 371-379Article in journal (Refereed)
    Abstract [en]

    We show new results from both the older and newer incarnations of AMANDA (AMANDA-B10 and AMANDA-II, respectively). These results demonstrate that AMANDA is a functioning, multipurpose detector with significant physics and astrophysics reach. They include a new higher-statistics measurement of the atmospheric muon neutrino flux and preliminary results from searches for a variety of sources of ultrahigh energy neutrinos: generic point sources, gamma-ray bursters and diffuse sources producing muons in the detector, and diffuse sources producing electromagnetic or hadronic showers in or near the detector.
