Measurement of inclusive jet and dijet cross sections in proton-proton collisions at 7 TeV centre-of-mass energy with the ATLAS detector
2011
Jet cross sections have been measured for the first time in proton-proton collisions at a centre-of-mass energy of 7 TeV using the ATLAS detector. The measurement uses an integrated luminosity of 17 nb−1 recorded at the Large Hadron Collider. The anti-k t algorithm is used to identify jets, with two jet resolution parameters, R=0.4 and 0.6. The dominant uncertainty comes from the jet energy scale, which is determined to within 7% for central jets above 60 GeV transverse momentum. Inclusive single-jet differential cross sections are presented as functions of jet transverse momentum and rapidity. Dijet cross sections are presented as functions of dijet mass and the angular variable χ. The res…
Measurements of underlying-event properties using neutral and charged particles in pp collisions at root s=900 GeV and root s=7 TeV with the ATLAS de…
2011
We present first measurements of charged and neutral particle-flow correlations in pp collisions using the ATLAS calorimeters. Data were collected in 2009 and 2010 at centre-of-mass energies of 900 GeV and 7 TeV. Events were selected using a minimum-bias trigger which required a charged particle in scintillation counters on either side of the interaction point. Particle flows, sensitive to the underlying event, are measured using clusters of energy in the ATLAS calorimeters, taking advantage of their fine granularity. No Monte Carlo generator used in this analysis can accurately describe the measurements. The results are independent of those based on charged particles measured by the ATLAS …
Luminosity determination in pp collisions at s=7 TeV using the ATLAS detector at the LHC
2011
Measurements of luminosity obtained using the ATLAS detector during early running of the Large Hadron Collider (LHC) at s√=7 TeV are presented. The luminosity is independently determined using several detectors and multiple algorithms, each having different acceptances, systematic uncertainties and sensitivity to background. The ratios of the luminosities obtained from these methods are monitored as a function of time and of μ, the average number of inelastic interactions per bunch crossing. Residual time- and μ-dependence between the methods is less than 2% for 0<μ<2.5. Absolute luminosity calibrations, performed using beam separation scans, have a common systematic uncertainty of ±11%, do…
Limits on the production of the standard model Higgs boson in pp collisions at root s=7 TeV with the ATLAS detector
2011
A search for the Standard Model Higgs boson at the Large Hadron Collider (LHC) running at a centre-of-mass energy of 7 TeV is reported, based on a total integrated luminosity of up to 40 pb−1 collected by the ATLAS detector in 2010. Several Higgs boson decay channels: H→γγ, H→ZZ(∗)→ℓℓℓℓ, H→ZZ→ℓℓνν, H→ZZ→ℓℓqq, H→WW(∗)→ℓνℓν and H→WW→ℓνqq (ℓ is e, μ) are combined in a mass range from 110 GeV to 600 GeV. The highest sensitivity is achieved in the mass range between 160 GeV and 170 GeV, where the expected 95% CL exclusion sensitivity is at Higgs boson production cross sections 2.3 times the Standard Model prediction. Upper limits on the cross section for its production are determined. Models wit…
Livshistorier i omsorgsarbeid
2023
Nyere helse- og omsorgspolitiske dokumenter løfter fram livshistorier som en viktig kilde til kunnskap i eldreomsorgen, og et relevant verktøy for profesjonelt omsorgsarbeid på sykehjemmet. Men hvilke utfordringer og muligheter ligger i livshistorier som omsorgsverktøy i praksis? Denne artikkelen er basert på et tverrfaglig samarbeidsprosjekt mellom forskere innenfor praksisfeltet, sykepleierstudenter, samfunnsvitere, helsevitere og humanister. Vår hensikt er å få ny kunnskap om utbredelse av livshistorier som omsorgsverktøy på sykehjem, og hva som karakteriserer slike verktøy. Ved hjelp av en kartleggingsstudie om livshistorier som et verktøy for dokumentasjon og kommunikasjon ved sykehjem…
Universities' mundaneness and regional engagement : Setting the stage
2022
This chapter introduces the main logic of this volume, which starts from the grassroots level of universities’ “everyday” engagements, looking at the manifold ways in which university knowledge agents build connections with multiple regional partners across the public and private sectors, and civic society more generally. Roles, functions and normative orientations of universities in the context of their surrounding regions have, in many cases, been taken for granted and, thus, have not been systematically addressed and/or still lack theorizing, due to the focus being on extraordinary, large-scale and eye-catching activities, and financially impressive transactions such as patents and spin-…
Universities and regions: New insights and emerging developments
2022
In this concluding chapter, the editors take stock of the empirical findings across the cases and levels of analysis and link the empirical evidence to the analytical framework presented in Chapter 2. In so doing, we revisit the interplay between macro, meso, and micro dimensions of the environments as well as the temporality in which higher education institutions (HEIs) operate, which, taken together, help shape the mundane (everyday) or routine behaviours of actors within HEIs. The editors conclude by suggesting that the empirical evidence and conceptual insights advanced in this volume represent a needed first step, yet more needs to be done (future studies) to further unpack how the dyn…
Unpacking Mundaneness : A novel conceptual framework for universities and regional engagement
2022
In this chapter, we debate the current view on university-regional engagements and suggest a renewed theoretical framework based on four main elements – macro, meso, micro dimensions, as well as a meta-dimension of temporality that cuts across all levels. The macro environment is typically defined as pertaining to public policies, culture, laws, and economy, while the meso environment includes links between the macro (societal) forces and the micro (agents) level through intermediate institutions and structures and is characterized by the processes and mechanisms of interaction of different actors. The micro level is about agency – organizations or individuals/groups within organizations – …
How and when does leader knowledge hiding trickle down the organisational hierarchy in the tourism context? A team-level analysis
2022
This research aims to extend the literature on knowledge hiding and tourism by integrating the theoretical frameworks of social exchange and social learning. Employee knowledge hiding has scarcely been examined in the tourism literature while leader knowledge hiding has not been analysed at all. Recognising that knowledge hiding can seriously undermine the ability of employees to offer innovative customer service and that leaders’ knowledge hiding may trigger knowledge hiding chain reactions among tourism employees, this study attempts to fill this gap. Utilising multi-source, multi-timed and multi-level data, we hypothesise a multi-level mediation wherein leader knowledge hiding trickles d…
Economic Geography of Innovation and Regional Development
2022
AbstractResearch in economic geography on innovation and regional development is an important and thriving research area in Scandinavia, which has contributed significantly to theoretical and empirical advancements beyond the Scandinavian research environments. This chapter demonstrates how the field has developed and changed its focus over the years, touching upon and developing around central academic and societal topics from deindustrialisation, clusters and regional innovation systems to creativity, green transition and changing regional development paths. The chapter focuses on how research milieus have developed in Scandinavia, how theories, methodologies and methods have advanced and…
