Om lönebildning
- 2020
-
Ingår i: Ekonomisk Debatt. - 0345-2646. ; 48:3, s. 37-48

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Denna artikel presenterar en modell av företags prissättning och efterfrågan på arbetskraft som gör det enklare att förstå lönebildningen och dess relation till inflation och arbetslöshet. Modellen gör det dessutom enklare att förstå hur lönenivån utvecklas genom lönenormering av en löneledande sektor – och vilka sektorer som bör ha inflytande på normbildningen och varför.

Intelligibility and perceptual ratings after treatment for laryngeal cancer: laryngectomy versus radiotherapy.
- 1998

Ingår i: The Laryngoscope. - 0023-852X. ; 108:1 Pt 1, s. 138-43

Tidskriftsartikel (refereegranskat)abstract
- In Sweden the most common treatment for T3-T4 laryngeal carcinoma is radical radiotherapy (with surgery for salvage), because the voice is thus preserved. A Swedish study showed that surgery yielded a significantly better 5-year survival and locoregional control at 3 years in T4 laryngeal carcinoma than radical radiotherapy. With these results in mind, we wanted to compare the different modes of treatment (surgery with a tracheoesophageal [TE] fistula and radical radiotherapy) with respect to the patients' speech proficiency. Twenty-eight subjects (with 14 patients in each treatment group) were judged by inexperienced and experienced listeners according to intelligibility by transcription and three perceptual ratings. From the perceptual ratings of speech intelligibility, voice quality, and speech acceptability we conclude that there is a significant difference, the irradiated speakers being rated higher than the tracheoesophageal speakers. It is also clear that most of the TE and irradiated laryngeal speaking patients are comparable to normal laryngeal speakers in intelligibility by transcription. Experienced and inexperienced listeners are able to rate TE and irradiated laryngeal speech reliably and similarly according to intelligibility by transcription. The inexperienced listeners rated the TE speakers significantly higher than did the experienced listeners.

Experiences from the production and homogeneity analysis of an AMS 14C sucrose standard for high-activity measurements
- 2010

Ingår i: Radiocarbon. - 0033-8222. ; 52:3, s. 1351-1357

Konferensbidrag (refereegranskat)abstract
- Accurate accelerator mass spectrometry (AMS) measurements rely on standards with well-known isotopic ratios. For radiocarbon measurements, a number of standards with different properties are commercially available, of which the IAEA-C6 sucrose standard with a 14C value of 150.61 pMC is the most active. When analyzing biological samples resulting from studies using 14C-labeled substances, the activity content can be up to 100 times this value. Thus, there is a need for a standard material with higher activity content than IAEA-C6 for making accurate AMS measurements on this type of sample. This paper describes the attempts of producing a standard with an activity content of about 10 times modern carbon. The material chosen has to be chemically inert, preferably non-toxic, commercially available in 14C-labeled form, and the activity must be homogeneously distributed within the material. Two different standard materials were considered: urea and sucrose. Sucrose was chosen for the new standard, since it is non-toxic, inexpensive, and organic and on combustion, forms only carbon dioxide (CO2) and water (H2O). In this paper, we discuss our experience in the production and homogeneity analysis of this material, from the crystallization of the sucrose solution to the graphitization of the samples. When using an online combustion method and a septa-sealed vial reduction method, the AMS measurements indicated that the activity was not homogeneously distributed throughout the material. Contrary to this, measurements of the sucrose solution prior to recrystallization indicated that the activity was more homogeneously distributed before than after the recrystallization. In order to determine whether the inhomogeneity depended on the graphitization method (i.e. the combustion or the reduction method) or on the material itself, 3 different graphitization methods and 2 different methods of recrystallization were tested.

Sperner's Problem for G-Independent Families
- 2015

Tidskriftsartikel (refereegranskat)abstract
- Given a graph G, let Q(G) denote the collection of all independent (edge-free) sets of vertices in G. We consider the problem of determining the size of a largest antichain in Q(G). When G is the edgeless graph, this problem is resolved by Sperner's theorem. In this paper, we focus on the case where G is the path of length n - 1, proving that the size of a maximal antichain is of the same order as the size of a largest layer of Q(G).

Codegree thresholds for covering 3-uniform hypergraphs
- 2016

Tidskriftsartikel (refereegranskat)abstract
- Given two 3-uniform hypergraphs F and G = (V, E), we say that G has an F-covering if we can cover V with copies of F. The minimum codegree of G is the largest integer d such that every pair of vertices from V is contained in at least d triples from E. Define c(2)(n, F) to be the largest minimum codegree among all n-vertex 3-graphs G that contain no F-covering. Determining c(2)(n, F) is a natural problem intermediate (but distinct) from the well-studied Turan problems and tiling problems. In this paper, we determine c(2)(n, K-4) (for n > 98) and the associated extremal configurations (for n > 998), where K-4 denotes the complete 3-graph on 4 vertices. We also obtain bounds on c(2)(n, F) which are apart by at most 2 in the cases where F is K-4(-) (K-4 with one edge removed), K-5(-), and the tight cycle C-5 on 5 vertices.

Measuring the Effect of Matching Problems on Unemployment
- 2020
-
Ingår i: International labour review (Print). - : Wiley. - 0020-7780 .- 1564-913X. ; 159:2, s. 243-258

Tidskriftsartikel (refereegranskat)abstract
- This paper shows how matching problems reduce employment – and hence also raise unemployment – by creating a gap between labour demand and employment. It also shows how this gap can be measured by unfilled jobs (unmet demand) as distinct from job vacancies (recruitment processes) and reports results from a vacancy survey which measures both. In fact, while a shift of the matching function indicating longer recruitment times suggests increasing matching problems, it is only the measurement of unfilled jobs which can verify this and at the same time quantify the effect on unemployment.

Noncooperative Flexible Pricing in a Homogenous Market
- 1986
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- A market is studied in which prices are set by the sellers, and where equilibrium is established through pure price adjustment. It is assumed that the sellers can observe each others' prices, and that each of them is free to instantly and costlessly change his price. In this setting it is shown that, when the number of competitors is large, a "cartel price", above the (Walrasian) competitive price, is an equilibrium - in fact the unique equilibrium price on the Pareto frontier.
