Held together by the bark : performance measurement and management as propagated by industry analysts
- 2014

In: International Journal of Business Performance Management. - : InderScience Publishers. - 1368-4892 .- 1741-5039. ; 15:3, s. 192-206

Journal article (peer-reviewed)abstract
- The purpose of this study is to explore what is propagated as performance measurement and management (PMM) by industry analysts. The rationale for targeting industry analysts is that this group constitutes a previously largely overlooked actor within the supply of management ideas. The study utilises empirical material in the form of proprietary reports marketed and sold by one of the largest industry analyst firms, through a dual analysis of history and content. As the findings show, there is a rich plethora of PMM incarnations stemming from one particular industry analyst report. Utilising rhetorical analysis, this piece of research is found to be lacking in sound argumentation opening up for significant doubts in terms of the validity of the subsequent incarnations. These findings are discussed in terms of implications for both research and practice.

Accounting Information Systems Implementation and Management Accounting Change
- 2014
-
In: Business Systems Research Journal. - : Walter de Gruyter GmbH. - 1847-8344 .- 1847-9375. ; 5:2, s. 125-138
-
Journal article (peer-reviewed)abstract
- Background: There is an on-going discussion within management accounting research regarding how to work with performance measures. In the process of developing new forms of performance measurement the task of choosing business metrics is central. This process is closely connected to the implementation of IT solutions. Objectives: In order to understand how new performance measurement solutions are implemented and used, it becomes crucial to understand how measures are selected and how new accounting information systems (AIS) are developed and implemented. Methods/approach: The paper builds on the case of an on-going AIS project at a large, public university in Sweden. The empirical material was collected using a semi-action research approach over a two-year period. The majority of the material comes from written documentation and minutes. Results: Even though the implementation of a new AIS triggers a change in the management accounting practice, this study shows that this is done in more than one perspective. Conclusions: As the project develops, new priorities and objectives evolve, which in the end shape what management accounting change becomes.

Strato-mesospheric Measurements of Carbon Monoxide with the Odin Sub-millimetre Radiometer: Retrieval and First Results
- 2004
-
In: Geophysical Research Letters. - 1944-8007 .- 0094-8276. ; 31:20
-
Journal article (peer-reviewed)abstract
- The Sub-Millimetre Radiometer (SMR) aboard the Odin satellite has been measuring vertical profiles of atmospheric trace gases since August 2001. We present the inversion methodology developed for CO measurements and the first retrieval results. CO can be retrieved from a single scan measurement throughout the middle atmosphere, with a typical resolution of similar to3 km and a relative error of similar to10% to similar to25%. Retrieval results are evaluated through comparison with data from the Whole Atmosphere Community Climate Model (WACCM) and observations of the Improved Stratospheric and Mesospheric Sounder (ISAMS) on board the Upper Atmospheric Research Satellite (UARS). Considering the large natural variability of CO, the SMR retrievals give good confirmation of the WACCM results, with an overall agreement within a factor of 2. ISAMS abundances are higher than SMR mixing ratios by a factor of 5-10 above 0.5 hPa from similar to80degreesS to similar to50degreesN.

G och K stjärnors effektiva temperaturer och deras kol-, kväve- och syrehalter
- 1983

Doctoral thesis (other academic/artistic)abstract
- This study is aimed at increasing our knowledge and understanding of the evolutionary stages during and after the main sequence phase. The study is based on new photometric and spectroscopic observations of stars in the region from the main sequence and up to the red giants. The observations are calibrated against existing theoretical stellar model atmospheres to give the fundamental parameters of the stars and their surface abundancies of carbon, nitrogen and oxygen. It consists of two articles in English and a summary in Swedish.In article I the the well observed nearby giant Arcturus is studied in order to obtain a relaible temperature of the star. By comparing the observed fluxdistribution with theoretical detailed model atmospheres a temperature of 4375 K is obtained. It is found that the uncertainty (50 K) is dominated by possible errors in the data for the H absorption.Article II makes use of the method developed in article I and temperatures and surface gravities are determined for 22 stars. Using the spectroscopic data, microturbulent velocities and iron abundancies are calibrated against the model calculations. With the fundamental parameters of the stars known C,N and 0 abundancies can now be obtained. It is found that material processed by the CN-cycle is found in stars more luminous than log L/L = 0.8. Stars with low 12C/13C ratios (< 15) are found down to the luminosity log L/L = 1.2. In stars where processed material is observed, C is deficent and N is enhanced. The C/N and 12C/13C and their correlation with stellar mass is found to be consistent with a slow mixing during the main sequence.

In: Advances in Space Research. - : Elsevier BV. - 0273-1177 .- 1879-1948. ; 36, s. 1031-1047
-
Journal article (peer-reviewed)abstract
- Astronomy highlights, mainly from the third year of Odin observations time shared 50/50% with aeronomy are presented: the very low O2 abundance limits achieved, the highly pressure broadened absorption lines of H2O, H218O, and CO (5 → 4) in the atmosphere of Mars, the high precision H2O and H218O observations of comets, the detections of NH3 and H2O around the C-rich star IRC+10216 (CW Leo) and of H2O around the O-rich star W Hya, NH3 and H2O observations of infall/outflow interactions, observations of H2O, H218O, H217O as well as NH3 and 15NH3 in multiple absorptions towards Sgr B2, and in emission towards Orion KL, the H2O detection of several new outflows in the DR21 W75S region. We also discuss the results of deconvolution of high S/N H2O, CO and 13CO (5 → 4) maps of the Orion KL region to 40″ resolution (the beam size of the Herschel telescope) and the first results from our ongoing “spectral scan” of Orion KL in bands around 555 and 570 GHz. Finally, a search for primordial molecules is presented.

Hydroxyl, water, ammonia, carbon monoxide and neutral carbon towards the Sgr A complex
- 2014
-
In: Proceedings of the International Astronomical Union. - 1743-9213 .- 1743-9221. ; 9:303, s. 97-99
-
Journal article (peer-reviewed)abstract
- We observed Hydroxyl, water, ammonia, carbon monoxide and neutral carbon towards the +50 km s−1 cloud (M−0.02−0.07), the circumnuclear disk (CND) and the +20 km s−1 (M−0.13−0.08) cloud in the Sgr A complex with the VLA, Odin and SEST. Strong OH absorption, H2O emission and absorption lines were seen at all three positions. Strong C18O emissions were seen towards the +50 and +20 km s−1 clouds. The CND is rich in H2O and OH, and these abundances are considerably higher than in the surrounding clouds, indicating that shocks, star formation and clump collisions prevail in those objects. A comparison with the literature reveals that it is likely that PDR chemistry including grain surface reactions, and perhaps also the influences of shocks has led to the observed abundances of the observed molecular species studied here. In the redward high-velocity line wings of both the +50 and +20 km s−1 clouds and the CND, the very high H2O abundances are suggested to be caused by the combined action of shock desorption from icy grain mantles and high-temperature, gas-phase shock chemistry. Only three of the molecules are briefly discussed here. For OH and H2O three of the nine observed positions are shown, while a map of the C18O emission is provided. An extensive paper was recently published with Open Access (Karlsson et al. 2013, A&A 554, A141).

Overview of the Martian atmospheric submillimetre sounder FIRE
- 2012
-
In: Planetary and Space Science. - : Elsevier BV. - 0032-0633 .- 1873-5088. ; 63-64:SI, s. 62-82
-
Journal article (peer-reviewed)abstract
- We propose a submillimetre-wave atmospheric emission sounding instrument, called Far-InfraRed Experiment (FIRE), for the Japanese Martian exploration programme "Mars Exploration with Lander-Orbiter Synergy" (MELOS). The scientific target of FIRE/MELOS is to understand the dust suspended meteorology of the Mars. FIRE will provide key meteorological parameters, such as atmospheric temperature profiles for outside and inside dust storms, the abundance profile of the atmospheric compositions and their isotopes, and wind velocity profiles. FIRE will also provide the local time dependency of these parameters. The observational sensitivity of FIRE/MELOS is discussed in this paper. FIRE will explore the meteorological system of the Martian atmosphere including the interaction between its surface and atmosphere.

Molecular oxygen in the rho Ophiuchi cloud
- 2007
-
In: Astronomy & Astrophysics. - : EDP Sciences. - 0004-6361 .- 1432-0746. ; 466:3, s. 5-
-
Journal article (peer-reviewed)abstract
- Context: Molecular oxygen, O2, has been expected historically to be an abundant component of the chemical species in molecular clouds and, as such, an important coolant of the dense interstellar medium. However, a number of attempts from both ground and from space have failed to detect O2 emission.Aims: The work described here uses heterodyne spectroscopy from space to search for molecular oxygen in the interstellar medium. Methods: The Odin satellite carries a 1.1 m sub-millimeter dish and a dedicated 119 GHz receiver for the ground state line of O2. Starting in 2002, the star forming molecular cloud core ρ Oph A was observed with Odin for 34 days during several observing runs.Results: We detect a spectral line at v_LSR =+3.5 km s-1 with Δ v_FWHM=1.5 km s-1, parameters which are also common to other species associated with ρ Oph A. This feature is identified as the O2 (NJ = 11 - 1_0) transition at 118 750.343 MHz.Conclusions: The abundance of molecular oxygen, relative to H{2} , is 5 × 10-8 averaged over the Odin beam. This abundance is consistently lower than previously reported upper limits.Based on observations with Odin, a Swedish-led satellite project funded jointly by the Swedish National Space Board (SNSB), the Canadian Space Agency (CSA), the National Technology Agency of Finland (Tekes) and Centre National d'Étude Spatiale (CNES). The Swedish Space Corporation has been the industrial prime contractor and also is operating the satellite. Appendix A is only available in electronic form at http://www.aanda.org
