    Ängsliga byråkrater eller professionella pragmatiker? : Administrativa effekter av statens indirekta styrning av kommunerna

    No full text
    Rapportens syfte är att undersöka och diskutera vilka administrativa effekter den indirekta statliga styrningen ger i den kommunala verksamheten. Kommunernas verksamheter styrs av en mängd olika styrsignaler, där styrningen sker i form av direkt, indirekt och efterhandsstyrning. Statliga myndigheter har i detta en roll som uttolkare, översättare och förmedlare av styrning. Studien visar att den komplexa styrbilden, mängden aktörer som är involverade i den indirekta styrningen, hörsammandet av efterhandsstyrningen och dominansen av ängsliga byråkrater och duktiga administratörer tillsammans bidrar till en överproduktion av administration inom skola, förskola och primärvård

    Effektivisering av vareflyt rundt prosessen fellemontering i produksjonen på Madshus

    Denne bacheloroppgaven er gjort i samarbeid med oppdragsgiver Madshus AS, Bjørn Myrhe gav oss tillit til å arbeide med frie hender. Formålet i denne oppgaven var å finne ut hvordan lean kunne brukes som et alternativ til automatisering rundt felleskiproduksjonen. Oppgaven er en casestudie hvor vi har benyttet oss av metodetriangulering for å besvare problemstillingen. Observasjoner, intervjuer og frekvensmålinger ble gjennomført i Madshus sine produksjonslokaler på Biri. Observasjonene ble gjort i form av en prosesskartlegging, etter det ble det gjennomført intervjuer med de ansatte som jobbet i de aktuelle prosessene. For å kvantifisere arbeidstiden ble det gjennomført frekvensmålinger på grunnlag av funnene fra prosesskartleggingen og intervjuene. En gjennomgang av relevant teori sammen med oppgavens resultater viser at lean ikke trenger å være et alternativ til automatisering, men heller kan bli brukt for å komplementere hverandre. Vi ser at Madshus kan gjøre store besparinger ved bruk av lean, men at man kan komme enda lenger med automatiseringer gjort på riktig måte – dog til en høyere investeringskostnad

    Search for Scalar Diphoton Resonances in the Mass Range 6560065-600 GeV with the ATLAS Detector in pppp Collision Data at s\sqrt{s} = 8 TeVTeV

    No full text
    A search for scalar particles decaying via narrow resonances into two photons in the mass range 65–600 GeV is performed using 20.3fb120.3\text{}\text{}{\mathrm{fb}}^{-1} of s=8TeV\sqrt{s}=8\text{}\text{}\mathrm{TeV} pppp collision data collected with the ATLAS detector at the Large Hadron Collider. The recently discovered Higgs boson is treated as a background. No significant evidence for an additional signal is observed. The results are presented as limits at the 95% confidence level on the production cross section of a scalar boson times branching ratio into two photons, in a fiducial volume where the reconstruction efficiency is approximately independent of the event topology. The upper limits set extend over a considerably wider mass range than previous searches

    Search for Higgs and ZZ Boson Decays to J/ψγJ/\psi\gamma and Υ(nS)γ\Upsilon(nS)\gamma with the ATLAS Detector

    No full text
    A search for the decays of the Higgs and ZZ bosons to J/ψγJ/\psi\gamma and Υ(nS)γ\Upsilon(nS)\gamma (n=1,2,3n=1,2,3) is performed with pppp collision data samples corresponding to integrated luminosities of up to 20.3fb120.3\mathrm{fb}^{-1} collected at s=8TeV\sqrt{s}=8\mathrm{TeV} with the ATLAS detector at the CERN Large Hadron Collider. No significant excess of events is observed above expected backgrounds and 95% CL upper limits are placed on the branching fractions. In the J/ψγJ/\psi\gamma final state the limits are 1.5×1031.5\times10^{-3} and 2.6×1062.6\times10^{-6} for the Higgs and ZZ bosons, respectively, while in the Υ(1S,2S,3S)γ\Upsilon(1S,2S,3S)\,\gamma final states the limits are (1.3,1.9,1.3)×103(1.3,1.9,1.3)\times10^{-3} and (3.4,6.5,5.4)×106(3.4,6.5,5.4)\times10^{-6}, respectively

    Professionals within the judicial system sometimes believe they can assess whether someone is lying or not based on cues such as body language and emotional expression. Research has, however, shown that this is impossible. The Finnish Supreme Court has also given rulings in accordance with this demonstrated fact. There has also been previous research on whether party or witness statements are assessed differently in court depending on whether they are given live, via videoconference, or via prerecorded video. In the present study, we investigated how a Finnish sample of district judges (N=47) assigned probative value to different variables concerning the statement or the statement giver, such as body language and emotional expression. We also investigated the connection between the judges’ beliefs about the relevance of body language and emotional expression and their preference for live statements or statements via videoconference. The judges reported assigning equal amounts of probative value to statements given live and statements given via videoconference. However, judges found it easier to detect deception live, and this preference correlated with how relevant they thought body language is when assessing the probative value of the statement. In other words, a slight bias to assess live statements more favorably than statements given via videoconference might still exist. More effort needs to be put into making judges and Supreme Courts aware of robust scientific results that have been the subject of decades of research, such as the fact that one cannot assess whether someone is lying or not based on cues such as body language

    Search for Scalar-Charm pair production in pp collisions at s=8\sqrt{s}=8 TeV with the ATLAS detector

    No full text
    The results of a dedicated search for pair production of scalar partners of charm quarks are reported. The search is based on an integrated luminosity of 20.3 fb1^{-1} of pp collisions at s=8\sqrt{s}=8 TeV recorded with the ATLAS detector at the LHC. The search is performed using events with large missing transverse momentum and at least two jets, where the two leading jets are each tagged as originating from c-quarks. Events containing isolated electrons or muons are vetoed. In an R-parity-conserving minimal supersymmetric scenario in which a single scalar-charm state is kinematically accessible, and where it decays exclusively into a charm quark and a neutralino, 95% confidence-level upper limits are obtained in the scalar-charm-neutralino mass plane such that, for neutralino masses below 200 GeV, scalar-charm masses up to 490 GeV are excluded
