    Faktorer som är av betydelse för långsiktigt viktminskningsresultat efter gastric bypass: En litteraturstudie2012Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syfte: Syftet med denna litteraturstudie var att sammanställa och beskriva faktorer som är av betydelse för långsiktigt viktminskningsresultat, mer än tre år efter gastric bypass.

    Metod: För att besvara studiens syfte gjordes en litteraturstudie med deskriptiv design. Studien har baserats på fjorton vetenskapliga artiklar som har sökts fram via Medline samt genom manuell sökning.

    Resultat: Studien visade att faktorer som var av betydelse för långsiktigt viktminskningsresultat var kost, fysisk aktivitet, beteende, uppföljning, preoperativ viktnedgång samt medicinska faktorer såsom utvidgning av magsäck och gastrojejunal stomi. God kostkvalitet och utövande av fysisk aktivitet visade sig ha ett signifikant samband med långsiktig viktminskning. Beteenden såsom kontroll över matbegär och ätvanor var av stor betydelse. Hetsätning visade sig påverka viktresultatet negativt. Patienter som gick på uppföljning visade större viktminskning på lång sikt liksom patienter som lyckades minska i vikt före operationen.

    Slutsats: Långsiktigt viktresultat efter gastric bypass kan förbättras genom rätt kost, fysisk aktivitet, långsiktig uppföljning samt genom att tidigt upptäcka ohälsosamma ätbeteenden. Mer forskning krävs angående faktorer som påverkar viktresultatet på lång sikt och vad sjukvården kan göra för att påverka dessa.

    Påverkas företagens prestanda av ett socialt ansvarstagande?2013Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Aim: Corporate Social Responsibility (CSR) is a widely known global concept and Swedish enterprises are considered to be cutting edge when it comes to taking responsibility. The main objective is to analyze if a large involvement in CSR gives Swedish companies a change in company value, and if it affects their profitability. An approximate Tobin’s Q is used to measure firm value and Return On Assets (ROA) is used to measure profitability.

     

    Method: A quantitative deductive method where investigation of secondary data will lead to an examination whether it is possible to demonstrate a relationship between CSR and firm value and/or profitability. Our secondary data is retrieved from Folksam Index for corporate responsibility 2009 and the corporate annual reports from 2011. Historical stock prices were collected from Nasdaq OMX Nordic webpage. After examination of the data a suitable analysis method will be chosen, which in this case resulted in multiple regression analysis.

     

    Result and Conclusions: The study shows that there is a statistically significant correlation between a high CSR and the approximate Tobin’s Q where increased CSR returns a reduced value of the firm. The study also shows a statistically significant positive correlation between CSR and ROA, where the model, however, have shortcomings. A general explanation for this is that there is no global concept for CSR and thus it is difficult to measure. In addition, difficulties were discovered regarding determining market value of Swedish firms as companies generally do not have all of their shares on the stock market and that there are different classes of shares.

     

    Suggestions for future research: One suggestion is a cross-sectional regression, similar to this study that compares different ways to define ROA and size. It would also be interesting to through a time series analysis be able to examine when, time wise, CSR activities makes an impact on Tobin’s Q and ROA.

     

    Contribution of the thesis: Identify influencing factors to contribute for a future benchmark of econometric models when measuring CSR.

    På vilket sätt kan idrott och hälsa, kost och motorisk träning påverka elevers lärande?2007Student paper second term, 10 points / 15 hpStudent thesis
    Abstract [sv]

    Antalet timmar inom ämnet idrott och hälsa i skolan dras ner allt mer, vilket framför allt kan påverka de elever som är fysiskt inaktiva på fritiden. Som effekt av detta har den svenska regeringen offentliggjort att eleverna bör rör på sig mer och de har därför infört 30 minuters obligatorisk daglig fysisk aktivitet på grundskolorna. Kommunerna väljer idag också att stänga allt fler lekparker vilket i längden kan leda till att den spontana leken hos elever på fritiden kan minskas. Detta kan leda till att den naturliga motoriken inte utvecklas som den ska. Eleverna får då inte utlopp för att röra sig tillräckligt mycket vilket kan leda till att deras motorik hämmas, vilket i sin tur kan leda till att deras läs- och skrivsvårigheter också påverkas negativt. Klyftan mellan fysiskt aktiva barn och fysiskt inaktiva barn ökar allt mer och som följd av detta kan det leda till en ond cirkel. Denna cirkel bör brytas i tid för att inte elever med motoriska svårigheter ska komma allt längre bort från sina jämnåriga klasskamrater. Kosten kan ha en stor betydelse för elevers lärande och koncentration. Om elever inte äter tillräckligt kan det vara många faktorer som påverkas negativt t ex, de får mindre ork, svårare att koncentrera sig och att den allmänna hälsan försämras.

    Studiens syfte har varit att studera faktorer som idrott och hälsa, kost och motorisk träning och om dessa faktorer kan påverkar elevers lärande eller inte. Studien har genomförts genom intervjuer på fem lärare på tre olika grundskolor.

    De intervjuade lärarna tycker att idrott och hälsa, kost och motorisk träning tillsammans är viktiga faktorer för elevers lärande, men de tycker också att valmöjlighet, elevvård och familjeförhållanden är faktorer som påverkar. Att eleverna får vara fysiskt aktiva leder till att de har lättare att koncentrera sig under skoltid. De intervjuade lärarna anser att kosten också har en stor betydelse för att eleverna ska kunna orka hela dagen i skolan. Den motoriska träningen bör tränas redan i tidig ålder, eftersom den kan hjälpa till att utveckla skriften och språket. Det som framkom framförallt i vår studie var att de intervjuade lärarna anser att dessa tre faktorer tillsammans blir en ”höjdare” för elevers lärande.

    The effects of stimulus complexity and conceptual fluency on aesthetic judgments of abstract art: Evidence for a default–interventionist account2018In: Metaphor and Symbol, ISSN 1092-6488, E-ISSN 1532-7868, Vol. 33, no 3, p. 235-252Article in journal (Refereed)
    Abstract [en]

    We report an experiment investigating how stimulus complexity and conceptual fluency (i.e., the ease of deriving meaning) influence aesthetic liking judgments for abstract artworks. We presented participants with paintings at two levels of complexity (high vs. low) and five levels of conceptual fluency (determined from a prior norming study) and requested separate ratings of beauty and creativity. Our predictions were derived from the PIA Model (Pleasure-Interest Model of Aesthetic Liking), which views aesthetic preferences as being formed by two, distinct fluency-based processes: an initial, automatic, stimulus-driven, default process and a subsequent, perceiver-driven deliberative process. A key trigger for deliberative processing is assumed to be disfluency at the default stage, as caused by factors such as visual complexity. We predicted that complexity and conceptual fluency would interact in determining aesthetic liking, with people preferring complex stimuli, but only when these are relatively easy to process conceptually. Our results supported this prediction for beauty judgments, although creativity judgments showed a curiously uniform profile. Nevertheless, the predictive capacity of the PIA Model in relation to beauty judgments attests to the explanatory strength of this default?interventionist theory of aesthetic liking. We conclude by noting important parallels between the PIA Model and the Revised Optimal Innovation Hypothesis, which likewise has broad reach in explaining how defaultness and non-defaultness affect pleasure across a range of linguistic and pictorial stimuli.

    Energy audit in Fridhemsskolan: A preschool in Gävle municipality2018Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This thesis is about the energy audit in Fridhemsskolan which is an educational facility. Fridhemsskolan is a preschool for children in Gävle municipality for children up to the age of six years and comprise of nine buildings in total. The project begins with an energy survey on the school facilities which ranges from checking the ventilation system, lightning system, number of occupants, equipment’s types and so on. The next step was to use a simulation program software called indoor climate and energy (IDA ICE) to create the base model for the building and input the data collected during the energy survey directly into the software and simulate it for a period of one year. After creating the base model, the total electricity use of the building was around 89 MWh/year while the district heating was 157 MWh/year.The energy conservation opportunities in Fridhemsskolan for the building was divide into two categories and these are referred to as non-retrofitting (no or minimal cost) and retrofitting (with cost) recommendations. The non-retrofitting involves reducing the indoor temperature and with this approach; the district heating consumption was reduced to 147.6 MWh/year which amount to 9.34 MWh/year in savings for the district heating while the electricity consumption was reduced to 86.4 MWh/year which amount to 2.6 MWh/year in savings for the electricity.Retrofitting (with cost) recommendations involves looking at the base model and see where some improvements can be carried out. In this research, the roof of the building has more energy losses and retrofitting with cost analysis was performed on that part of the building envelope.After retrofit, the district heating consumption was reduced to 142 MWh/year which is about 15 MWh/year in saving for the district heating while the electricity consumption was reduced to 26 MWh/year which also amount to 63 MWh/year saving in electricity consumption. The reason for this sharp decrease in the electrical consumption was because, the electrical radiators in the base model of the building was replaced with ideal heaters that uses district heating as the energy carrier and 170 mm of mineral wool was also added to the roof.Finally the research further looks at the thermal comfort and the indoor air quality of the occupants in the building by analysing the data on both thermal comfort and the indoor air quality to see if the value obtained are within the acceptable range. In most cases the value is within the acceptable range like in the case of carbon dioxide (CO₂) concentration in theiiioccupied zone, the value obtained after reducing the indoor temperature was less than 1000 parts-per-million (ppm) and that shows that the carbon dioxide (CO₂) concentration is within an acceptable level in the room. The thermal comfort of the occupants in the occupied zone was within the acceptable limit. However, lowering indoor temperature increases the PPD for both buildings. The percentage of the total occupant hours with thermal dissatisfaction increases to 13% from 14 % for Hus 9 and from 13% to 15% for Hus (4-8).

    University of Gävle Environmental Performance After ISO 14001 CertificationReflected by Students’ Environmental Awareness2010Independent thesis Advanced level (degree of Master (One Year)), 15 credits / 22,5 HE creditsStudent thesis
    Abstract [en]

    Environmental problems are seen as the first priority that all countries try to find as a solution to be more sustainable. These issues arise due to the lack of our responsibility to the world. Researchers agree on that the starting point in changing our society to be green is to increase environmental awareness (Jiang et al., 1999). Several sectors accept this idea like UNESCO which focuses on education as a tool to promote sustainable development (UNESCO, 2002).

     

    Following UNESCO, our study investigates university students’ environmental awareness. The Authors hope that the outcome not only reflects university performance, but also helps to develop the environment in the future.  Hence, the authors selected the University of Gävle or HiG, as a case study because it is a best practice in Environmental Management System (EMS). Moreover, HiG received the ISO 14001 certificate and it has a continuous improvement program (Sammalisto, 2007, p.69). 

     

    The study was started by reviewing research literatures concerning Environmental Management System (EMS), Sustainable Development (SD), Education for Sustainable Development (ESD) and Environmental Awareness. The authors found that there are few studies talking about students’ awareness in universities after being awarded ISO 14001. Notice that the research was seen only from environmental perspective (Flint, 2004).

     

    To answer research questions, two surveys were adopted. The first part focused on teachers and officers (or staffs) who work on environmental issues. While, the second part focused on the students which were divided into Swedish and international.

     

    The research outcomes indicate that HiG has a good EMS performance supported by annual environmental audits, regular policy revision and the attempts to minimize non-conformities. Conversely, when the authors pointed at student awareness, it shows that students have insufficient environmental knowledge. Moreover, some students have lower environmental awareness and act in a less ecological friendly way. Nevertheless, a knowledge problem was also found among several university staffs. This is because of the lack of communication about environmental issues inside the staffs community and lack of environmental education for students.

     

    Whatever the university situation is, there are some groups of staff and students eager to develop themselves and their university. This point of strength could be the best driving force. It can push the university forward until the university reaches sustainable development and it brings the aware graduates into society.

    Det onda och den onde: kontrasterande uppfattningar om det onda inom katolska kyrkan2006Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The nature of evil is clearly defined in catholic dogma and tradition but, though very rarely addressed, what is actually preached and transmitted in pastoral context often differs significantly from this line of thought. Based on the experience that the topic is often evaded or treated poorly, as well as on information concerning a recent increase in reports of demonic possession in western society, this study explored the schism within the church concerning evil. It was noted that embarrassment - as in the face of 21st century-enlightened-thought the Church still officially states the existence of the Devil and associated malevolent spirits - seems to have promoted an intellectual cover-up. While not desiring to inhibit freedom of thought or opinion, this work aimed at establishing clarity, coherence and truthfulness concerning teachings of the Church, and implications. It was argued that left in the dark as to the Church’s concept of spiritual reality, and ensuing controversy, the laity is not given fair opportunity to make existential choices, reach own conclusions or put forth important questions and issues for debate. The study was grounded in a systematic presentation of catholic dogma on evil, followed by a phenomenologically inspired method of analysis. Recent theological arguments put forth by the New Theology were related to extracts of an extensive interview with a catholic exorcist in Sweden (included in full). It was shown how the traditional Christian idea of Jesus Christ is inseparably bound up with, and based on, the concept of spiritual forces of light/good and darkness/evil, mutually repelling each other. It was concluded therefore that annihilation of the devil in one way or another, inevitably ends up by making the incarnation pointless, deconstructing not only traditional concepts of evil but the whole Christian idea in itself. The need for open discussion was stressed, including uncomfortable implications of belief in the existence of a spiritual evil.

    ”… Even a Spirit Could Benefit From Therapy”: nya kunskaper och kontroverser kring besatthet i västerländsk kultur2007Independent thesis Advanced level (degree of Master (One Year)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Possession is a transcultural and transhistorical phenomena that in recent times appears to have had a resurge within western culture. Heavily laden with controversy, incredulity and prejudice possession is not readily dealt with, although many people present in parishes and for psychiatric treatment with symptoms and disturbances that need to be addressed promptly with up-to-date skill and discernment. Lack of interest and practise has been the rule not only in secular science but in major religious contexts as well. An increasing amount of literature highlights the lack of efficient psychiatric and religious response. In this work traditional Christian perspectives on possession were related to recent Psychiatric and Parapsychological results, definitions and conclusions, the aim being to enhance and enrich our understanding of what is being interpreted as an involuntary influence of malevolent spirits on human beings. The method of the study was based on reflexivity, including aspects of phenomenological analysis, critical theory and postmodern theory. It was shown that a clear line can no longer be drawn between science and spirituality as concerning possession, its cure and its etiology; that exorcism and other methods of spirit-expulsion have a not insignificant actuality in international psychiatry of today as a remedy for certain states of dissociative disorders, and that these methods are considered extremely powerful. The study also focused on agents responsible for treating people with related symptoms, religious as well as seculars, and on the need for continued interdisciplinary study and approach to the phenomena of possession. It was stressed that our understanding of this issue is in dire need of revision.

    Längtan efter helhet : Svenska kyrkan mellan arv och förnyelse: en analys av tanke och handling inom Svenska kyrkan i några av dess möten med nutida sökande efter helhet2004Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    An issue of central interest today is the aspiration for wholeness, on the one hand referring to the concept of “healing” (swed: helande), on the other hand to being “whole” (swed: hel); body, mind, soul, spirit and relations. The need and desire to offer a more holistic experience is becoming prominent also within the Swedish Church. This paper addressed some events within the Swedish Church that cater to experiences of wholeness, with the aim of exploring how this is done in practise and how it’s rooted in Christian thought. Events were experienced by participant observation as far as possible and theoretical/theological issues addressed in interviews with initiators, as well as extracted from some current literature. The material was analysed from a hermeneutically inspired stance, addressing different possibilities of interpretation. The study found that the material could be roughly divided into two groups; one turning back toward patrimony and lost traditions for renewed nourishment and enhanced experience, the other turning toward foreign or newer religious/spiritual traditions and movements, applying new practices and concepts. It was noted that current theological discussion of innovation was lagging far behind what was actually being performed in various parishes. Theological debate also seemed to neglect the concept of “healing”, while this aspect came across as being of major importance in most observed events. Theory and practise seemed to live in separate realities. Although lacking in clarity, in common grounds and common values, the Swedish Church was seen to offer a broad and interesting range of holistic experiences, with or without Christian connections.

    Litar du på din internetbank?: Effekterna av förtroende för acceptansen av internetbanker2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syfte: Syftet med denna studie är att genom en kvantitativ undersökning skapa förståelse för olika dimensioner av förtroende för internetbanker. Detta gör vi genom en replikerande studie av Suh och Han’s undersökning från 2002.

    Metod: Vår studie är baserad på en kvantitativ forskningsmetod i form av en webbaserad enkätundersökning. Enkäten skickades ut till ungefär 380 personer som gav oss 150 representativa svar tillbaka. Det empiriska materialet analyserades sedan i statistikprogrammet SPSS där det genomfördes tre analyser: korrelationsanalys, faktoranalys och klusteranalys.

    Resultat & Analys: Resultatet visar att förtroende är den högst aktuella egenskapen för att kunder ska använda internetbank. Modellen TAM visas även vara aktuell, där användarvänligheten och nyttan påverkar attityden betydligt.

    Förslag till vidare forskning: Studien gör en undersökning där modellen TAM är aktuell med en förlängning vilket är förtroende. Det skulle vara intressant att testa denna modell på en annan marknad och se om verkligen förtroendet är lika aktuellt på en ”icke känslig” marknad.

    Uppsatsens bidrag: Uppsatsen bidrar med vetskap om att förtroende är en avgörande faktor för acceptansen av internetbanker. Även att hur användaren upplever internetbankens hemsida, huruvida de kan göra det som de vill på den aktuella sidan.

    Nyckelord: Kundförtroende, internetbanker, TAM.

    Multifactor productivity in the Construction Industry Under Imperfect Competition2008In: The ICFAI University Journal of Industrial Economics, ISSN 0972-9208, Vol. 5, no 3, p. 7-34Article in journal (Refereed)
    Abstract [en]

    The present study suggests a generalization of the standard translog cost function model, incorporating the demand side of the market into the analysis. The main advantage of this generalized model is that it can be used to directly investigate the degree of monopoly power in the market under study, using the Lerner index as the empirical measure of market power. The Swedish construction industry is used as an empirical example of how to apply this method. Within the framework of the neoclassical theory of production, cost and factor demand functions as well as an expression equating marginal cost to marginal revenue are estimated. The paper finds substitutability between capital and labor and between labor and materials, the returns to scale are found to be increasing, while introduction of new technology is found to reduce the total cost of production. Finally, on average, the Lerner index amounts to 15.1% per annum suggesting that the Swedish construction industry possesses some monopoly power in the market for its product. This result also suggests that the results from cost function analysis, not taking the possibility of market power into account, might be biased due to misspecification of the model.

    Grekerna och krisen II: – en undersökning utifrån ett diskursanalytiskt perspektiv2012Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syftet med uppsatsen har varit att undersöka hur två av Sveriges största dagstidningar, Dagens Nyheter och Aftonbladet, valt att beskriva greker och Grekland under en av den finansiella krisens första intensiva rapporteringsperioder under 2011. Min avsikt har varit att utifrån ett diskursanalytiskt perspektiv, undersöka huruvida vissa teoretikers, bland annat Simon Cottle och Teun Van Dijks påståenden om mediernas framställning av vissa grupper under pågående krissituationer stämmer överens med Dagens Nyheters och Aftonbladets framställning av grekerna under den ekonomiska krisen.

    I uppsatsen har jag fördjupat mig i sex artiklar. Genom att ha studerat den litteratur av relevans för mitt arbete har jag velat undersöka huruvida det går att koppla teorierna i litteraturen till artiklarnas innehåll.

    Efter att ha analyserat de sex artiklarna som publicerats under en av de mest bevakade perioderna under 2011 är min uppfattning att flertalet av de tidigare nämnda teoretikers påståenden om mediernas framställning av vissa grupper (i detta fall greker), under pågående krissituationer, stämmer överensstämmer med Dagens Nyheters och Aftonbladets framställning av grekerna under juni 2011.

    Combined Gravimetric-Seismic Moho Model of Tibet2018In: Geosciences, ISSN 2076-3263, Vol. 8, no 12, article id UNSP 461Article in journal (Refereed)
    Abstract [en]

    Substantial progress has been achieved over the last four decades to better understand a deep structure in the Himalayas and Tibet. Nevertheless, the remoteness of this part of the world still considerably limits the use of seismic data. A possible way to overcome this practical restriction partially is to use products from the Earth’s satellite observation systems. Global topographic data are provided by the Shuttle Radar Topography Mission (SRTM). Global gravitational models have been derived from observables delivered by the gravity-dedicated satellite missions, such as the Gravity Recovery and Climate Experiment (GRACE) and the Gravity field and steady-state Ocean Circulation Explorer (GOCE). Optimally, the topographic and gravity data should be combined with available results from tomographic surveys to interpret the lithospheric structure, including also a Moho relief. In this study, we use seismic, gravity, and topographic data to estimate the Moho depth under orogenic structures of the Himalayas and Tibet. The combined Moho model is computed based on solving the Vening Meinesz-Moritz (VMM) inverse problem of isostasy, while incorporating seismic data to constrain the gravimetric solution. The result of the combined gravimetric-seismic data analysis exhibits an anticipated more detailed structure of the Moho geometry when compared to the solution obtained merely from seismic data. This is especially evident over regions with sparse seismic data coverage. The newly-determined combined Moho model of Tibet shows a typical contrast between a thick crustal structure of orogenic formations compared to a thinner crust of continental basins. The Moho depth under most of the Himalayas and the Tibetan Plateau is typically within 60-70 km. The maximum Moho deepening of similar to 76 km occurs to the south of the Bangong-Nujiang suture under the Lhasa terrane. Local maxima of the Moho depth to similar to 74 km are also found beneath Taksha at the Karakoram fault. This Moho pattern generally agrees with the findings from existing gravimetric and seismic studies, but some inconsistencies are also identified and discussed in this study.

    Combined Gravimetric–Seismic Crustal Model for Antarctica2018In: Surveys in geophysics, ISSN 0169-3298, E-ISSN 1573-0956, Vol. 39, no 1, p. 23-56Article in journal (Refereed)
    Abstract [en]

    The latest seismic data and improved information about the subglacial bedrock relief are used in this study to estimate the sediment and crustal thickness under the Antarctic continent. Since large parts of Antarctica are not yet covered by seismic surveys, the gravity and crustal structure models are used to interpolate the Moho information where seismic data are missing. The gravity information is also extended offshore to detect the Moho under continental margins and neighboring oceanic crust. The processing strategy involves the solution to the Vening Meinesz-Moritz’s inverse problem of isostasy constrained on seismic data. A comparison of our new results with existing studies indicates a substantial improvement in the sediment and crustal models. The seismic data analysis shows significant sediment accumulations in Antarctica, with broad sedimentary basins. According to our result, the maximum sediment thickness in Antarctica is about 15 km under Filchner-Ronne Ice Shelf. The Moho relief closely resembles major geological and tectonic features. A rather thick continental crust of East Antarctic Craton is separated from a complex geological/tectonic structure of West Antarctica by the Transantarctic Mountains. The average Moho depth of 34.1 km under the Antarctic continent slightly differs from previous estimates. A maximum Moho deepening of 58.2 km under the Gamburtsev Subglacial Mountains in East Antarctica confirmed the presence of deep and compact orogenic roots. Another large Moho depth in East Antarctica is detected under Dronning Maud Land with two orogenic roots under Wohlthat Massif (48–50 km) and the Kottas Mountains (48–50 km) that are separated by a relatively thin crust along Jutulstraumen Rift. The Moho depth under central parts of the Transantarctic Mountains reaches 46 km. The maximum Moho deepening (34–38 km) in West Antarctica is under the Antarctic Peninsula. The Moho depth minima in East Antarctica are found under the Lambert Trench (24–28 km), while in West Antarctica the Moho depth minima are along the West Antarctic Rift System under the Bentley depression (20–22 km) and Ross Sea Ice Shelf (16–24 km). The gravimetric result confirmed a maximum extension of the Antarctic continental margins under the Ross Sea Embayment and the Weddell Sea Embayment with an extremely thin continental crust (10–20 km).

    Produktinformationens inverkan på returer inom e-handel: Fallstudie på tre företag inom modebranschen2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Med e-handelns snabba expansion har även returerna ökat, returvolymen inom e-handel kan vara så hög som 50% (Dissanayake och Singh, 2007). Returer kostar inte bara pengar utan påverkar även miljön i form av bl.a. ökade transporter. De vanligaste returorsakerna inom modebranschen är storlek och passform vilket kan härledas till bristande produktinformation som t.ex. undermåliga storleksguider. Tidigare forskning om produktinformation har oftast berört vikten av produktinformation vid konsumentköp samt vilka egenskaper i produktinformationen som är viktiga. (Chiu et al, 2014; Manvai och Venkataram, 2005; Markopoulos, Arin och Ungar, 2016) Syftet med denna fallstudie är att undersöka hur produktinformationen påverkar antalet produktreturer hos e-handelsföretag i modebranschen. Studiens frågeställningar berör hur fallföretagen arbetar med produktinformation och om det har påverkat returvolymen samt fallföretagens hållbarhetsarbete. Studien är baserad på en kvalitativ metod och med hjälp av semistrukturerade intervjuer med tre fallföretag besvaras studiens syfte och frågeställningar. Fallföretagen i denna studie arbetar med försäljning inom modebranschen, två av dessa är stora företag och har både fysiska butiker och e-handel. Det tredje fallföretaget är ett mindre företag som enbart har e-handel. Studien visar att fallföretagen får samma gynnsamma effekt av arbetet med produktinformation även om drivkraften bakom arbetet är olika. Studien visar även att produktinformationen kan ses som en kanal för att effektivt förmedla hållbarhetsarbete till kunderna. Studien bidrar med bredare kunskap om produktinformation samt att studien kan ligga till grund för vidare forskning om produktinformationens inverkan på returer. Studien styrker även vissa delar av tidigare forskning inom returer i modebranschen.

    Experimenting in HRI for priming real world set-ups, innovations and products2014In: HRI '14 Proceedings of the 2014 ACM/IEEE international conference on Human-robot interaction, New York: ACM Digital Library, 2014, p. 511-512Conference paper (Refereed)
    Abstract [en]

    Robotics is moving towards real world applications, beyond the well-structured environment of industrial robotics. In the world of assistant robots and medical robots, Human-Robot Interaction is essential. Also in emerging industrial scenarios there is a need of the human to be closely included in the loop. The companies are confronted with the lack of guidelines and of standards on how the higher features of HRI may be safely incorporated. Although the scientific research is burgeoning and worthy of praise, it is clear that its results are scattered and not capable of giving a clear input to be easily taken up by companies and standardization organizations like ISO and IEC. The workshop aims at the integration of empirical findings into complex real world robot systems by focusing on three typical sectors (industrial, service and medical) to develop systematic approaches to benchmark and evaluate experimental systems so that normative results can be realized rapidly. The present workshop focuses on bringing together scientists, representative of robotics companies and of standardization working groups to foster discussion in the definition of experimental scenarios and protocols in HRI, so to be able to prime real world set-ups and help realize the robotic products of the future.

    Representation of people with disabilities: A content analysis of Russian press2012Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    The aim of this study was to examine how Russian press represents people with disabilities. The study was conducted using the method of qualitative content analysis. The material for the analysis consisted of sixty articles selected from Russian's four national newspapers. The study covered a period of the year 2011. Labeling theory and stigma were used for the analysis of the results. The results showed that Russian press described discrimination of people with disabilities, social support provided to them by the Government and their active way of life. The newspaper articles mentioned that the Russian Government tries to integrate disabled people into society. The study did not find any significant differences in the representation of people with disabilities in various newspapers. It was found that the articles covered physical disabilities, such as mobility, hearing and visual impairments.

    Fractional models for modeling complex linear systems under poor frequency resolution measurements2013In: Digital signal processing (Print), ISSN 1051-2004, E-ISSN 1095-4333, Vol. 23, no 4, p. 1084-1093Article in journal (Refereed)
    Abstract [en]

    When modeling a linear system in a parametric way, one needs to deal with (i) model structure selection, (ii) model order selection as well as (iii) an accurate fit of the model. The most popular model structure for linear systems has a rational form which reveals crucial physical information and insight due to the accessibility of poles and zeros. In the model order selection step, one needs to specify the number of poles and zeros in the model. Automated model order selectors like Akaikeʼs Information Criterion (AIC) and the Minimum Description Length (MDL) are popular choices. A large model order in combination with poles and zeros lying closer to each other in frequency than the frequency resolution indicates that the modeled system exhibits some fractional behavior. Classical integer order techniques cannot handle this fractional behavior due to the fact that the poles and zeros are lying to close to each other to be resolvable and not enough data is available for the classical integer order identification procedure. In this paper, we study the use of fractional order poles and zeros and introduce a fully automated algorithm which (i) estimates a large integer order model, (ii) detects the fractional behavior, and (iii) identifies a fractional order system.

    Comparison of sedentary behaviors in office workers using sit-stand tables with and without semi-automated position changes2017In: Human Factors, ISSN 0018-7208, E-ISSN 1547-8181, Vol. 59, no 5, p. 782-795Article in journal (Refereed)
    Abstract [en]

    Objective: This study compared usage patterns of two different electronically controlled sit-stand tables during a 2-month intervention period among office workers.

    Background: Office workers spend most of their working time sitting, which is likely detrimental to health. Although the introduction of sit-stand tables has been suggested as an effective intervention to decrease sitting time, limited evidence is available on usage patterns of sit-stand tables, and whether patterns   are influenced by table configuration.

    Methods: Twelve workers were provided with standard sit-stand tables (non-automated table group) and 12 with semi-automated sit-stand tables programmed to change table position according to a pre-set pattern, if the user agreed to the system-generated prompt (semi-automated table group). Table position was monitored continuously for two months after introducing the tables, as a proxy for sit-stand behavior.

    Results: On average, the table was in a “sit” position for 85% of the work-day in both groups; this did not change significantly during the 2-month period. Switches in table position from sit to stand were, however, more frequent in the semi-automated table group than in the non-automated table group (0.65 vs. 0.29 hr-1; p=0.001).

    Conclusion: Introducing a semi-automated sit-stand table appeared to be an attractive alternative to a standard sit-stand table, since it led to more posture variation.

    Application: A semi-automated sit-stand table may effectively contribute to making postures more variable among office workers, and thus aid in alleviating negative health effects of extensive sitting.

    Sit-stand tables with semi-automated position changes: a new interactive approach for reducing sitting in office work2017In: IISE Transactions on Occupational Ergonomics and Human Factors, ISSN 2472-5838, Vol. 5, no 1, p. 39-46Article in journal (Refereed)
    Abstract [en]

    Background: Introduction of sit-stand tables has been proposed as an initiative to decrease sedentary behavior among office workers and thus reduce risks of negative cardiometabolic health effects. However, ensuring proper and sustainable use of such tables has remained a challenge for successful implementation. Objective: We developed a new system to promote and sustain the use of sit-stand tables. Methods: The system was programmed to change the position of the table between “sit” and “stand” positions according to a regular pre-set pattern, if the user agreed to the system-generated prompts prior to each change. The user could respond to the system-generated prompts by agreeing, refusing or delaying the changes by 2 minutes. We obtained user compliance data when this system was programmed to a schedule of 10 minutes of standing after every 50 minutes of sitting. Compliance was investigated in nine office workers who were offered the semi-automated sit-stand table for two months. Results: On average, the system issued 12-14 alerts per day throughout the period. Average acceptance rate ranged from 75.0-82.4%, and refusal rate ranged from 11.8-10.1% between the first and eighth weeks of intervention (difference not statistically significant). During the first week after introduction, the table was in a standing position for 75.2 min on average, increasing slightly to 77.5 min in the eighth week. Conclusion: Since the workers were essentially sitting down before the table was introduced, these results suggest that the system was accepted well, and led to an effective reduction of sitting during working hours. Users also reported that the system contributed positively to their health and wellbeing, without interrupt their regular work, and that they would like to continue using the sit-stand table even beyond the two-month period, as part of their regular work. Compliance beyond two months of use, however, needs to be verified.

    Use of sit-stand stations during the first 2 months after their introduction2016Conference paper (Refereed)
    Abstract [en]

    Background. There is increasing evidence that sedentary behaviour during the workday is associated with negative health effects. In this context, interventions to reduce total sedentary time and breaking up periods of continuous sitting during computerized office work are urgently needed. Several reviews conclude that introducing sit-stand stations may lead to positive effects, but they also state that long-term interventions in real occu-pational settings are still rare. Therefore, the aim of this study was to investigate usage of sit-stand tables among Brazilian office workers during an intervention lasting two months.

    Methods.Nine office workers (6 females, 3 males; age 42 [SD 12] years) participated. The workers received traditional sit-stand tables and ergonomics information. They then used the workstation for two months. The tables were furnished with a system that recorded and kept track of table use during the intervention period. Table use early and late in the intervention period was compared using the Wilcoxon signed-rank test for repeated measurements.

    Results. In the beginning of the eight-week intervention period, workers, in median, changed table position 2.4 (1.9 – 4.7) times per day, decreasing to 2.3 (1.0 – 3.3) times at the end (P=0.09). Moreover, we also found a non-significant decrease in total time stand-ing per day, from 88.6 (67.4 – 94.3) minutes to 58.8 (33.1 – 95.7) minutes (P=0.31).

    Discussion. Two months after introducing sit-stand tables, some decrease in usage could be seen, if not statistically significant. Based on this, we emphasize that introduction of sit-stand tables should be accompanied by continued encouragement of the workers, preferably informed by a personalized follow up of actual use.

    The ability of non-computer tasks to increase biomechanical exposure variability in computer-intensive office work2015In: Ergonomics, ISSN 0014-0139, E-ISSN 1366-5847, Vol. 58, no 1, p. 50-64Article in journal (Refereed)
    Abstract [en]

    Postures and muscle activity in the upper body were recorded from 50 academics office workers during 2 hours of normal work, categorised by observation into computer work (CW) and three non-computer (NC) tasks (NC seated work, NC standing/walking work and breaks). NC tasks differed significantly in exposures from CW, with standing/walking NC tasks representing the largest contrasts for most of the exposure variables. For the majority of workers, exposure variability was larger in their present job than in CW alone, as measured by the job variability ratio (JVR), i.e. the ratio between min–min variabilities in the job and in CW. Calculations of JVRs for simulated jobs containing different proportions of CW showed that variability could, indeed, be increased by redistributing available tasks, but that substantial increases could only be achieved by introducing more vigorous tasks in the job, in casu illustrated by cleaning.

    Neck, trunk, and upper arm posture variation during computer work at a sit-stand table in a real work setting2019Conference paper (Refereed)
    Abstract [en]

    Background: Computer work is generally associated with constrained postures and sedentary behaviors. Sit-stand tables have been suggested as an effective intervention to promote changes in gross body posture, and thus reduce sitting. However, few studies have addressed to what extent sit-stand table usage affects posture variation in other body regions. The aim of this study was to examine neck, trunk and arm postures among office workers with access to sit-stand tables.

    Methods: Twenty-four office workers (16 females, 8 males; mean age 41 (SD9) years) participated. At entry, workers received sit-stand tables, which were then used for two months. Neck and trunk flexion, and right upper arm elevation (RUA) was recorded on three consecutive days, two hours/day, during the last week of table use. Minute-to-minute variability for the three postures during sitting (CWsit) and standing (CWstand) computer work was obtained for each participant. Job variance ratios (JVR) were calculated for the actual work, and for other combinations of CWsit and CWstand by simulation1.

    Results: CWsit and CWstand were performed for 72% and 28% of the time spent at the computer. Minute-to-minute variability was larger in CWsit than in CWstand for all three postures, and the difference CWsit-CWstand was largest for RUA [median 1.7 (IQR −0.2–1.7)º], followed by trunk [1.6 (0.9–3.0)º] and neck [0.9 (0.0–3.1)º]. During actual work, JVR was between 1 and 3 for most participants. Simulations suggested that maximum variability would occur at a combination of 40–80% CWsit and 20–60% CWstand.

    Conclusion: Neck, trunk and arm posture variation during computer work can be increased by manipulating proportions of time spent sitting and standing at a sit-stand table. The tentative “optimal” proportions reported here could be a benchmark for occupational health professionals.

    The effect of sit-stand workstations to decrease sedentariness in office work: tests of 2 systems with and without automatic reminders2016Conference paper (Refereed)
    Abstract [en]

    Sedentary behaviors in office workers has become a major public health concern and several initiatives have been proposed to break up sedentary behavior patterns during the performance of computer-intensive office work. Among such initiatives, the use of sit-stand workstations has been suggested to be one of the most promising by recent reviews. However, there still is only limited scientific evidence showing how effective sit-stand workstations are, in reducing sedentary behaviors and also documentation of their sustainability of use in studies of regular office work (i.e. as the “newness” of the system wears off, with time since introduction). This study aimed to document user behaviors and compare the use of two sit-stand workstation based interventions among two groups of administrative office workers: an “autonomous” group in which these workstations were introduced following some general ergonomic guidelines, and another “feedback-system” group in which the sit-stand tables were furnished with a semi-automatic reminder system, programmed to raise the table to a high (i.e. standing) position for 10 minutes after every accumulated 50 minutes of the table being in a low (i.e. sitting) position, i.e. to result in about 83% sitting per day. In addition, the sustainability of the use of these two kinds of sit-stand workstation interventions over two continuous months since their introduction was also studied. The results averaged over two months of usage of the two interventions showed that the percentage (%) sitting time was 87.4 (84.9-89.2) on average in the autonomous group and 84.0 (83.5-85.4) on average in the feedback-system group (P=0.001), and the frequency of switches between sitting and standing was 0.3 (0.2-0.3) per hour in the autonomous group and 0.7 (0.6-0.7) per hour in the feedback-system group (P=0.001). Thus, the sit-stand table system integrated with the automatic reminder system led to more reduction in sitting time and more switches in posture between sitting and standing as compared to the traditional sit-stand table, and behaviors of both groups were seen to be sustained over the 2-month intervention period (no difference across time for any of the variables tested for any group).

    Variation in upper extremity, neck and trunk postures when performing computer work at a sit-stand station2019In: Applied Ergonomics, ISSN 0003-6870, E-ISSN 1872-9126, Vol. 75, p. 120-128Article in journal (Refereed)
    Abstract [en]

    The aim of this study was to determine the extent of upper arm, neck and trunk posture variation that can be obtained by combining seated and standing computer work, compared to performing only seated computer work. Posture data were recorded for two hours during each of three days of ordinary work from 24 office workers that had been using a sit-stand station for two months. Periods with sitting and standing computer work were identified using on-site observations, and posture means and minute-to-minute variance were determined for both. Expected minute-to-minute posture variability in different temporal combinations of sitting and standing computer work were determined by simulation, and expressed in terms of a Job Variance Ratio, i.e. the relative increase in variability compared to sitting-only work. For all three postures, mean values differed between sitting and standing computer work, and both showed a notable minute-to-minute variability. For most workers, posture variability was larger when combining sitting and standing than when sitting only, and simulations suggested to introduce more standing than what the worker currently practiced. The results indicate that introducing a sit-stand table could, for most office workers, have a positive effect on upper arm, neck and trunk posture variability.

    Variation in upper trapezius and wrist extensor EMG among office workers during sit-stand table use in a real work setting2019Conference paper (Refereed)
    Abstract [en]

    Background: Computer work is generally associated with constrained postures and low muscular demands. Sit-stand tables have been suggested as an effective initiative to change working postures during computer work, but the effect of this intervention on muscle activation has rarely been studied. The aim of this study was to document variation in shoulder-arm muscle activation among office workers using sit-stand tables.

    Methods: Twenty-four office workers (16 females, 8 males; age 41±9 years) participated. At entry, workers received sit-stand tables and ergonomics information, and then used the table for two months. Muscle activity of right and left upper trapezius and wrist extensors (RUT, LUT, RWE and LWE, respectively) was recorded during three consecutive days (two hours each day) in the last week of sit-stand table usage. Periods of computer work in sitting and standing positions (CWsit and CWstand, respectively) were identified by on-site observation, and synchronized with the EMG recordings. Variability (min-min SD across 1-minute bins, %MVE) was calculated for each EMG recording in CWsit and CWstand.

    Results: During the 62 minutes of EMG recorded during computer work, CWsit was performed for 72% and CWstand for 28% of the time. The mean minute-to-minute variability of trapezius EMG was larger (P<0.05) during CWsit (RUT 3.9 (SD between workers 1.6) %MVE; LUT 3.9 (SD 2.3) %MVE) than CWstand (RUT 3.0 (SD 1.5) %MVE; LUT 3.2 (SD 1.9) %MVE). The mean minute-to minute variability in RWE was also larger during CWsit (3.3 (SD 1.4) %MVE) than CWstand (2.9 (SD 1.3) %MVE). For LWE, variability did not differ between CWsit and CWstand.

    Conclusion: Sitting and standing computer work was associated with different extents of variation in shoulder-arm muscle activity. Thus, sit-stand tables may introduce beneficial exposure variation into the work of office employees.

    Samlärande i en additiv språkmiljö: En studie där barn, vårdnadshavare och pedagoger i samverkan stärker barns identiteter och språkutveckling, utifrån individernas erfarenheter, miljöer och kulturer2012Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [sv]

    Sammanfattning Syftet med föreliggande examensarbete var att undersöka hur barn med annat modersmål än svenska och deras vårdnadshavare, tillsammans med pedagoger och oss kan utveckla arbetssätt och metoder som stärker barns och vårdnadshavare identitet, samt utvecklar och stödjer språkutvecklingen. Syftet var också att utifrån dessa metoder och arbetssätt utarbeta ett metodhäfte. Detta examensarbete baseras på kvalitativ aktionsforskning ur ett interpretivistiskt perspektiv. Metoderna som använts är intervjuer, observationer, dokumentation och gruppstärkande övningar/lekar. Deltagarna har varit barn och vårdnadshavare från kurdiska, somaliska och arabisktalande språkgrupper samt pedagoger. Vårt examensarbete utgår från ett sociohistoriskt och -kulturellt perspektiv, vilket enligt Strandberg (2006) med utgångspunkt i Vygotskij (1978) innefattar detsociala (interaktionen med andra människor), det medierade (artefakter; verktyg och tecken), det situerade (i kulturella kontexter och speciella situationer) och detkreativa (baserat på barns fantasi och kreativitet). Vår studie är även baserad på didaktik och filosofier som Montessori och Reggio Emilia. Den tidigare forskning som ligger till grund för vår undersökning är forskning om identitet, flerspråkighet, vårdnadshavarens roll och betydelse samt språkutveckling hos yngre barn. Resultaten visar att barnets sociala samspel med vårdnadshavare, pedagoger och med andra barn har haft betydelse för barnets språkutveckling och stärkandet av identiteten. Resultaten visar även att samlärande i en stimulerande miljö med hjälp av skapandet av pedagogiska leksaker och spel utifrån barnets kontext, samt att barnen använt sin kreativitet har varit av vikt för studiens resultat. Slutligen har resultatet lett till skapande av ett metodhäfte som dels utgår från informanternas gemensamma aktiviteter, men även från det urval av metoder och perspektiv, som beskrivs i vår teoretiska bakgrund. Metodhäftet kan användas i hemmen, i förskolor och i kontakt mellan förskola och hemmen.

    A Simple Nonparametric Preprocessing Technique to Correct for Nonstationary Effects in Measured Data2012In: IEEE Transactions on Instrumentation and Measurement, ISSN 0018-9456, E-ISSN 1557-9662, Vol. 61, no 8, p. 2085-2094Article in journal (Refereed)
    Abstract [en]

    The general approach for modeling systems assumes that the measured signals are (weakly) stationary, i.e., the power spectrum is time invariant. However, the stationarity assumption is violated when: 1) transient effects due to experimental conditions are dominant; 2) data are missing due to, for instance, sensor failure; or 3) the amplitude of the excitation signals smoothly varies over time due to, for instance, actuator problems. Although different methods exist to deal with each of these nonstationary effects specifically, no unified approach is available. In this paper, a new and general technique is presented to handle nonstationary effects, based on processing overlapping subrecords of the measured data. The proposed method is a simple preprocessing step where the user does not need to specify which nonstationary effect is present, nor the time interval where the nonstationary effect appears. The merits of the proposed approach are demonstrated on an operational wireless system suffering from interrupted link effects.

    Fractional-Order Time Series Models for Extracting the Haemodynamic Response From Functional Magnetic Resonance Imaging Data2012In: IEEE Transactions on Biomedical Engineering, ISSN 0018-9294, E-ISSN 1558-2531, Vol. 59, no 8, p. 2264-2272Article in journal (Refereed)
    Abstract [en]

    The postprocessing of functional magnetic resonance imaging (fMRI) data to study the brain functions deals mainly with two objectives: signal detection and extraction of the haemodynamic response. Signal detection consists of exploring and detecting those areas of the brain that are triggered due to an external stimulus. Extraction of the haemodynamic response deals with describing and measuring the physiological process of activated regions in the brain due to stimulus. The haemodynamic response represents the change in oxygen levels since the brain functions require more glucose and oxygen upon stimulus that implies a change in blood flow. In the literature, different approaches to estimate and model the haemodynamic response have been proposed. These approaches can be discriminated in model structures that either provide a proper representation of the obtained measurements but provide no or a limited amount of physiological information, or provide physiological insight but lacks a proper fit to the data. In this paper, a novel model structure is studied for describing the haemodynamics in fMRI measurements: fractional models. We show that these models are flexible enough to describe the gathered data with the additional merit of providing physiological information.

    Abstract [en]

    The main objective of this study was to study individuals experience of panic disorder. The underlying method in the study was of qualitative art, were theme based analysis were used and semi structured interviews were conducted. Six interviews were conducted with individuals that for themselves or with the help of primary care for filled the DSM-IV criteria for panic disorder. The results showed that the participants felt that their panic disorder was more or less prominent depended on the stability of the participants subsistence. The participants felt less of their panic disorder if they had a more stable subsistence and felt the panic-disorder were more prominent if the participants felt more stressed. The interviews led to four themes, The Individuals experience of panic disorder, life situation, sense of losing control and a sense of no one would understand.

    The effect of a thin foil on the heat losses behind a radiator2013Independent thesis Advanced level (degree of Master (One Year)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

     

    This thesis work is the study of the effect of an aluminium foil on the losses that produced by a radiator, situated under a window, through the wall behind it. The reason behind this topic is due to the energy problem and the different goals that governments have set up to try to reduce the use of energy. For example, more specifically a Swedish national goal is to decrease the energy use of the built stock with 50% by 2050.

     

    For this purpose, an experimental set-up was built in the University of Gävle, Sweden. The arrangement was composed by a radiator and a window facing a climate chamber. A total of twenty-one temperatures and two heat fluxes in the exterior wall were measured in the set-up. Ten different measurement scenarios with different radiator temperature, 40°C, 50°C and 60°C; two different distance between the radiator and the wall, 5 and 9 centimetres and with and without the aluminium foil, were performed.

     

    With the experimental results, a CFD model was validated. Two different models were done, first a 2D model and afterwards a 3D model. For the turbulence, the chosen model was standard k-ε model. There were 54 cases simulated with the 2D model and the 3D model was used just for validation. The cases had different variables such as radiator temperature, outdoor temperature and wall insulation. With these cases, analysis of the effectiveness of the presence of an aluminium foil behind the radiator is performed to evaluate if there is a significant reduction of the losses.

     

    The results showed with both methods that the aluminium foil reduces the losses of the wall behind the radiator. The savings varied depending on the boundary conditions of the case and it were obtained a maximum of 4% and a minimum of 1,3%.

    Abstract [en]

    Title: Har chefer slutat lyssna? – en studie om kommunikationstillfredsställelse och

    chefers aktiva lyssnande.

    Level: Final assignment for Bachelor Degree in Business Administration.

    Author: Michel Barjakob, Mathias Johansson.

    Supervisor: Kristina Mickelsson, Pär Vilhelmson.

    Date: 2016 – january

    Aim: In this study we aim to create a deeper understanding in supervisors active listening and how it shapes employees communication satisfaction.

    Method: Due to the aim of the study, which is to create a deeper understanding in supervisors active listening, we have conducted a qualitative research. Data has been gathered through semi-structured interviews with ten employees from a leading electronic store and was conducted in Gävle. 

    Result & conclusions: The study show that supervisors must possess enough communication competence to know when active listening should be used. Supervisors communication competence shapes the employees communication satisfaction meanwhile most supervisors lack knowledge in active listening.

    Suggestions for future research: Our suggestions for future research are based on this study’s qualitative research. The participants have requested a follow-up of the active listening. A further recommendation for further research is to examine the impact active listening has on company results.

    Contribution of the thesis: The study contributes by filling the gap we found in our research area. A theoretical model was developed based on previous research, which helped find and localize communication and satisfaction and its components. The practical contribution is aimed towards supervisors hoping to receive knowledge in active listening to help them communicate with their co-workers.

    Key words: communication competence, active listening, communication satisfaction, job satisfaction, shape.

    Abstract [en]

    The purpose of this thesis is to illustrate the subject areas of communication and organizational theories. And what is significant in the daily work within Länsförsäkringar Gävleborg regarding to our subject areas which have been chosen.

    This thesis establishes that a sense of participation is significant and fundamental for communication. This is something that the theories we investigated advocates and correspond with the reality presented in the thesis. Furthermore we have also discovered that the agencys have devoloped their own ways of working and so called subcultures, which the co-workers are comfortable with. We believe that more active knowledge dispersion between the agencys is necessary and further more when the organization is based on knowledge.

    Sophämtares fysiska och psykosociala arbetsbelastning2016Report (Other academic)
    Abstract [sv]

    Arbetet som sophämtare inkluderar manuell hantering som hämtning och hantering av hushållsavfall i kärl och säckar. Det finns tidigare studier som visat att arbetet kan vara tungt med en hög helkroppsbelastning. Tungt arbete förknippas ofta med besvär i rörelseorganen. Psykologiska påfrestningar i arbetet kan också bidra till besvärsuppkomst.

    Biltrafikens arbetsgivarförbund och Svenska Transportarbetareförbundet tog gemensamt initiativ till det här projektet ”Sophämtarnas arbetsmiljö - allas ansvar”. Projektet har utförts av Transportfackens Yrkes- och Arbetsmiljönämnd (TYA) i samarbete med Karolinska Institutet (KI) och Centrum för belastningsskadeforskning (CBF) vid Högskolan i Gävle. I den här delen av projektet var syftet att kartlägga branschens förekomst av arbetsrelaterade besvär och undersöka den fysiska och psykosociala arbetsbelastningen hos sophämtare vid arbete med insamling av hushållsavfall.

    Samtliga Sveriges sophämtare som arbetar med insamling av hushållsavfall, knappt 2000, erbjöds att fylla i ett omfattande frågeformulär avseende arbete och hälsa. Sextiosex procent svarade. Inom projektetet genomfördes också heldagsmätningar av puls och arbetsställningar för rygg och armar på 56 sophämtare som arbetade med baklastande sopbil. På 12 sophämtare som arbetade med sidlastande sopbil genomfördes dessutom mätningar av muskelbelastning i skulder- och underarmsmuskulatur under en hel arbetsdag. I samband med heldagsmätningarna observerades sophämtarnas arbete av en observatör från en efterföljande bil, eller via en personburen videokamera. För att få fram ytterligare information om belastning på skuldror, rygg och knän genomfördes även biomekaniska fältexperiment där sophämtare fick utföra typiska arbetssituationer samtidigt som förekommande skjut- och drag-krafter registrerades.

    Enligt enkätundersökningen ansåg 17 procent av sophämtarna att deras fysiska arbetsförmåga var låg, vilket är samma procentandel som tidigare har registrerats hos flygplanslastare, men något bättre än vad man brukar se bland män med kort utbildningstid.

    Det var vanligare med kroppsliga besvär bland sophämtare än generellt i befolkningen. Andelen med besvär för olika kroppsdelar som skuldror (60 procent), ländrygg (62 procent), nacke (49 procent), händer/handleder (44 procent), motsvarade situationen för flygplanslastare; det fanns dock en skillnad för knän, där 52 procent av sophämtarna hade besvär mot 44 procent av flyglastarna.

    Sophämtarnas psykosociala arbetsbelastning liknade i stort den hos flygplanslastare, och motsvarar generellt förhållandena i den arbetande befolkningen. I genomsnitt rapporterar sophämtarna även samma upplevda stöd ifrån ledningen som andra yrkesgrupper, men sophämtare på arbetsställen med särskilt lågt stöd ifrån ledningen rapporterade fler olyckstillfällen, hade högre förekomst av kroppsliga besvär och lägre arbetsförmåga än sophämtare på arbetsställen med högt stöd. Mycket talande var att många fler, 27 procent skattade låg psykisk arbetsförmåga av dem på arbetsställen med generellt lågt upplevt stöd från ledningen jämfört med 8 procent av dem på arbetsställen med högt stöd.

    Det var vanligare med olycksfallstillbud bland de som angav ett ständigt högt arbetstempo, vilka återfanns både bland de som svarade att de, 64 procent av sophämtarna, som fick och bland de som inte fick gå hem tidigare om de var klara med dagens uppgifter.

    Fyrtiofyra procent av sophämtarna svarade att de en eller flera gånger hade råkat ut för olycksfall som lett till sjukskrivning. Halkolyckor var klart vanligast. Bland de som rapporterade ett ständigt högt arbetstempo var det vanligare med olyckor.

    De 41 kvinnor som ingick i enkätstudien rapporterade generellt högre upplevd fysisk och psykosocial belastning, samt sämre hälsa och arbetsförmåga än sina manliga kollegor.

    Heldagsmätningarna visade att baklastarnas genomsnittliga arbetstid utanför depån var drygt 6½ timma, varav 43 procent utgjordes av bilkörning. Pulsmätningarna visade, liksom enkäterna, att hämtning från flerbostadhus var mera belastande än hämtning i villaområden och på landsbygden. Pulsen var stundtals hög, men i genomsnitt var den för de flesta sophämtare acceptabel enligt internationella rekommendationer.

    De biomekaniska analyserna visade att krafterna vid dragning av sopkärl ibland var höga, speciellt på snöunderlag, men de föreföll inte att innebära några tydliga risker för ländryggen enligt amerikanska rekommendationer för acceptabla nivåer. Det finns dock forskning som indikerar att upprepad exponering för höga dragkrafter kan innebära risk för skulderbesvär. Att hoppa eller att gå framlänges ned från styrhytt var förknippat med knäbesvär, och kan enligt de biomekaniska analyserna även ge höga ländryggsbelastningar.

    Mot bakgrund av dessa resultat kan några rekommendationer/frågeställningar i syfte att förbättra arbetsmiljön vara följande:

    Kan man öka stödet från ledningen? Ledarskaps- och arbetsmiljöutbildning för första linjens chefer? Strategi vid chefsrekrytering?

    Kan man påverka sophämtarna att inte arbeta i ett ”onödigt” högt tempo, om det egentligen inte är bråttom?

    Kan man se till att det finns tid (eller om det redan finns tid, att få sophämtarna att använda denna tid) att arbeta i ett rimligt tempo, och kanske hjälpas åt vid hantering av mycket tunga kärl?

    Kan man få alla att ta sig ner från hytten på "rätt sätt"? Kan man i större utsträckning använda sopbilar med låga insteg?

    Sjuksköterskors reflektioner om hur de uppnår ett gott bemötande av patienter: en intervjustudie2014Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The aim of this study was to describe experienced registrered nurses (RNs) reflections regarding

    creating a good interaction with patients i.e how the RNs are/behave towards patients, how the RNs

    come across. The study had a descriptive design and was conducted as six semi structured

    interviews with experienced RNs, all working on different adult somatic wards. The results were

    analysed using qualitative content analysis. It highlighted the importance of creating an open

    atmosphere by being available and the key aspects of communication such as, actively listening and

    being perceptive to the unspoken word. Consciously mirroring their own spoken word with their

    body language and using body contact also conveyed positive communication to patients.

    Conveying open mindness and respect motivated patients to be involved in their own care. The RNs

    had to be aware of past patient hospital experiences and being self aware, in particular of their own

    limitations, benefitted both patients and RNs. Positive effects were shown when patients responded

    with signs of well-being and faith in the RNs. When RNs came across well generated this too

    personal satisfaction for the RNs.

    Kan fysisk träning i anslutning till arbetet förbättra muskuloskeletal hälsa?: en kunskapsöversikt2006Report (Other academic)
    Abstract [en]

    This literature review gives support for a positive health effect of regular physical exercise matching the physical demands at work and the anatomical origin of disorder:

    -specific trunk muscle exercises ca 1–2 times/week can have a positive effect on low back disorders among women/men with heavy vigorous or varied job tasks working in different health care or industrial settings

    -specific shoulder-arm and neck exercises ca 1–2 times/week can have a positive effect on neck-shoulder and neck disorders, respectively, among women with light repetitive or monotonous job tasks working in different office settings.

    Overall, associations between physical exercise and improvement in related physical performance and musculoskeletal health – disorders were found in those studies which met the criteria of randomized allocation, specified exercises, frequency and duration of the exercise session and documented effect from exercise on the corresponding physical capacity. Minor or major methodological deficiencies are, however, present in many of the intervention studies that impair the assessment as they can lead to an over- as well as an underestimation of the effect of training. Future studies should therefore focus on high methodological quality especially regarding 1) research design, inclusion criteria, allocation to intervention and control group; 2) exercise program, registration of compliance to training and changes of occupational load; 3) high accuracy of the effect measures

    Prediction of development of fatigue during a simulated ambulance work task from physical performance tests2004In: Ergonomics, ISSN 0014-0139, E-ISSN 1366-5847, Vol. 47, no 11, p. 1238-1250Article in journal (Refereed)
    Abstract [en]

    The aims of this study were (1) to identify which physical performance tests could best explain the development of fatigue during a simulated ambulance work task, (2) to investigate the effect of height and weight and (3) to investigate in what respects these findings differ between female and male ambulance personnel. Forty-eight male and 17 female ambulance personnel completed a test battery assessing cardio-respiratory capacity, muscular strength and endurance, and co-ordination. The subjects also completed a simulated ambulance work task -- carrying a loaded stretcher. The work task was evaluated by development of fatigue. Univariate and multiple regression analyses were used to investigate to what extent the tests in the test battery were able to explain the variance of developed fatigue. The explained variance was higher for female than for male ambulance personnel (time > 70% of HRpeak: R2 = 0.75 vs 0.10, accumulated lactate: R2 = 0.62 vs 0.42, perceived exertion: R2 = 0.75 vs 0.10). Significant predictors in the models were VO2max, isometric back endurance, one-leg rising, isokinetic knee flexion and shoulder extension strength. Height, but not weight, could further explain the variance. The high physical strain during carrying the loaded stretcher implies the importance of investigating whether improved performance, matching the occupational demands, could decrease the development of fatigue during strenuous tasks.

    Relationships between physical activity and physical capacity in adolescent females and bone mass in adulthood2006In: Scandinavian Journal of Medicine and Science in Sports, ISSN 0905-7188, E-ISSN 1600-0838, Vol. 16, no 6, p. 447-455Article in journal (Refereed)
    Abstract [en]

    This study investigates whether physical activity and physical performance in adolescence are positively related to adult bone mineral density (BMD). In 1974, physical activity, endurance, and muscular strength were measured in 204 randomly selected female students, age 16.1 +/- 0.3 year (range 15-17 years). Twenty years later, 36 of the women volunteered to undergo a measurement of their BMD. Women who were members in a sports club in adolescence had significantly higher adult BMD (mean differences of 5% to 17% depending on site) compared with subjects who were not engaged in a sports club. Furthermore, women with persistent weight-bearing activity in adulthood had significantly higher BMD compared with women who had stopped being active or had never been active. The differences ranged between 5% and 19% with the highest difference found in trochanter BMD. Stepwise regression analyses showed that membership in a sports club at baseline was a significant independent predictor of BMD in the total body, lumbar spine, legs, trochanter, and femoral neck, explaining 17-26% of the variation in BMD. Change in body weight was a strong independent predictor of BMD of the total body and arms, explaining 8% of the variation in both sites. In addition, running performance at baseline was an independent predictor of total body BMD, whereas the two-hand lift performance significantly predicted BMD of the total body, legs and trochanter. The hanging leg-lift and handgrip were both significant predictors of arm BMD. In conclusion, membership in a sports club and site-specific physical performance in adolescence together with the change in body weight were significantly associated with adult BMD in premenopausal women

    When is it Necessary to Use Muscle Systems to Enhance 3D Animation?2009Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

     

    To build muscles to enhance the animation of a 3D character takes more time and effort than the standard character rig. In some cases, the muscles will not be noticeable and therefore are unnecessary. This research tried to find the moments when the muscles did or did not make a difference. The new Maya Muscle System is also explored and the procedure to create muscles for a standard rig is explained. The test that was performed showed that the muscles are more noticeable in all cases.

    Förrättningslantmätarens hantering av stiftelser utifrån Kammarkollegiets och tillsynsmyndigheternas prövningar2013Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Huvudsyftet med studien var att utreda och klargöra hur förrättningslantmätaren bör handla när en stiftelse blir sakägare i en lantmäteriförrättning och hur stiftelsen ska behandlas utifrån förrättningslantmätarens undersökningsplikt. Studien hade även två delsyften där det första skulle beskriva och analysera hur stiftelsers föreskrifter kan ändras, medan de andra skulle utreda hur tillsynsmyndigheternas registrering av stiftelser genomförs. Förrättningslantmätare är en yrkesroll inom lantmäterimyndigheten och har till uppgift att handlägga samt besluta i fastighetsbildnings-ärenden. Lantmäterimyndigheten är den myndighet som har till uppgift att ansvara för att en effektiv och rättssäker fastighetsindelning genomförs. En stiftelse är en typ av juridisk person som bildas av en eller flera personer för att verka för ett bestämt ändamål. Stiftelsen ska förvalta en ekonomisk förmögenhet som har avsatts för ett bestämt ändamål, där förvaltningen ska ske över en längre tid. Förmögenheten kan bestå av fast egendom i form av fastigheter.

    Metoder som använts för att besvara studiens syften och forskningsfrågor var en litteraturstudie, en intervjustudie och en fallstudie. Litteraturstudien granskade tidigare forskning inom ämnes-området, lagstiftningen och facklitteratur för att ge en vetenskaplig grund. Intervjustudien genom-fördes för att få en grundlig förståelse för hur tillsynsmyndigheternas och Kammarkollegiets prövningar går till vid ändring av stiftelsers föreskrifter. Fallstudien granskade och jämförde tillsynsmyndigheternas och Kammarkollegiets prövningar vid ändring av stiftelsers föreskrifter, men fallstudien jämförde även vilka dokument tillsynsmyndigheterna kräver in av en stiftelse när den ska registreras. Intervjuer gjordes i fallstudien med samtliga tillsynsmyndigheter för att samla information om hur deras prövningar går till när stiftelser ska registreras i stiftelseregistren.

    Resultatet av litteraturstudien bestod av beskrivningar av förrättningslantmätarens yrkesroll, fastighets-, ägande- och stiftelsebegreppet. Resultatet av intervjustudien visade att de intervjuade tillsynsmyndigheterna och Kammarkollegiet har olika grundliga prövningar vid ändring av stiftelsers föreskrifter. Detta visade även fallstudien samt att tillsynsmyndigheternas prövningar skiljer sig åt vid registrering av en stiftelse. Slutsatsen beskriver hur förrättningslantmätaren ska handla när en stiftelse blir sakägare i en lantmäteriförrättning och hur stiftelsen ska behandlas utifrån förrättningslantmätarens undersökningsplikt. Två mallar finns i slutsatsen som innehåller riktlinjer för hur en kontroll av stiftelsens föreskrifter kan göras för att vara säker på att fastighets-bildningen inte strider mot stiftelsens föreskrifter.

    Examining Relations Between Public Participationand Public Expenditure: Opinions from English and French Users on Environmental Issues in the English Channel2019In: Sustainability, ISSN 2071-1050, E-ISSN 2071-1050, Vol. 11, no 8, article id 2230Article in journal (Refereed)
    Abstract [en]

    Governments need to decide how to allocate their public expenditure, which is commonly misconstrued as simply targeting social issues. Most scientific literature highlights that the role of public spending is to enhance social welfare and fight poverty and inequality. Nonetheless, public expenditure also includes spending on environmental issues. This paper analyses relations between public participation, support for public expenditure, and pro-environmental behaviour (PEB) intentions in the English Channel region. An online public survey was developed to investigate public use of the English and French sides and the public's willingness to change their behaviour to better protect the Channel region. The survey was undertaken in the summer of 2014 and was answered by 2000 respondents. The Channel region public is willing to participate more in behaviour that involves direct changes or switches between buying/purchasing choices. In contrast, there is less willingness to engage in pro-environmental behaviour intentions that involve more active engagement activities. French respondents were slightly less inclined to change their consumer behaviour intentions, while women and older people were slightly more likely to do so. This research shows that pro-environmental behaviour could positively affect support for proposed public expenditure on environmental issues.
