Artiklen behandler de svenske pensionistorganisationers tilbøjelighed til at beskrive de ældre som en samfundsøkono-misk »risikogruppe«. Organisationernes ældrebilleder sættes ind i en samfundsmæssig kontekst, der viser at holdnin-gerne til ældre direkte afspejler omgivelsernes. Håkan Jönson er ph.d. i socialt arbejde, socionom og forsker ved Socialhøjskolen i Lund, Sverige. Hans afhandling behand

Objectives: The degree to which treatment with tumour necrosis factor (TNF) antagonists may be associated with increased risks for serious infections is unclear. An observational cohort study was performed using prospectively collected data from the Swedish Biologics Register (ARTIS) and other national Swedish registers. Methods: First, in the ARTIS, all 4167 rheumatoid arthritis ( RA) patients st

In order to test the hypothesis of an interaction between neck proprioception and the vestibulo-ocular reflex (VOR), we rotated 16 healthy subjects both facing forward and with their heads passively turned 70 degrees to either side. We found that gain tended to be lower when the subjects were rotated with their heads turned opposite to the direction of rotation compared to when they were rotated i

Enzyme partitioning and recovery with a new aqueous two-phase system based on commercially available hydroxypropyl starch Reppal PES 200 and the thermo-separating polymer Ucon 50-HB-5100 was studied. Ucon is an ethylene oxide-propylene oxide random copolymer. A culture supernatant of Aspergillus niger containing extracellular beta-mannanase and alpha-galactosidase was partitioned in two steps. The

We consider estimation of frequency offset (FO) and equalization of a wireless communication channel, within a general framework which allows for different frequency offsets for various multipaths. Such a scenario may arise due to different Doppler shifts associated with various multipaths, or in situations where multiple basestations are used to transmit identical information. For this general fr

Aim: To determine whether self-esteem among children with cystic fibrosis (CF) and their healthy siblings differs from that of a healthy reference group and whether there are differences within and between sibling pairs. Methods: All Swedish CF children 6–14 y old with a healthy sibling in the same age range (n=65) were invited to participate, 55 sibling pairs and their parents taking part in the

Unsupervised classification is a very common problem in pattern recognition even when the classes are known. In many areas intra-class variations may be greater than the inter-class variations causing a need for a subdivision of the training set of a class into smaller subunits often referred to as clusters. The subdivision or clustering is often performed independently of the relative properties

The exceptionally high luminosities of gamma-ray bursts (GRBs), gradually emerging as extremely useful probes of star formation, make them promising tools for exploration of the high-redshift Universe. Here we present a carefully selected sample of Swift GRBs, intended to estimate in an unbiased way the GRB mean redshift (z(mean)), constraints on the fraction of high-redshift bursts and an upper l

The aim was to compare the abilities of contrast-enhanced CT, non-contrast-enhanced MR imaging and contrast-enhanced MR imaging using standard (0.1 mmol/kg b.w.) and high (0.3 mmol/kg b.w.) doses of Gadodiamide injection to detect brain metastases (i.e. blood-brain barrier damage). Sixteen patients with at least 2 metastases found by CT were evaluated by MR imaging using non-contrast-enhanced spin

The electronic structure of the strongly Coulomb correlated cuprate CuGeO3 has been calculated by the local-density-approximation method (LDA+U). The parameter U was varied from 0 to 8 eV. The results of the band-structure calculations are compared with experimental data obtained by means of X-ray photoelectron and resonant X-ray emission spectroscopy methods (Cu Lalpha and O Kalpha X-ray emission

In rats the flow of urine was diverted from the bladder over a period of 7-10 days. Active length-tension curves of muscle strips of such disused bladders did not differ from those of controls, provided lengths were related to optimum length for force development. When, however, lengths were related to length in situ the active length-tension curves were shifted to the left. The muscle strips of t

Implicit figuration and subjective interpretation make up the conventional basis of the classical discussion of the omprehensiveness and aesthetic quality of the metaphor.Its function and use in Social Science is illustrated as a background to a radical different methodological approach. By means of Perspective Text Analysis it is demonstrated that the metaphor has to be conceived as the Re-naming

A DNA variation in the coding region of the human cystatin C gene has been detected by direct sequencing. The polymorphism, a G/A transition, leads to an Ala/Thr variation in the penultimate amino acid of the signal peptide. The base substitution results in the loss of a SstII restriction site, thus allowing the design of a rapid polymerase chain reaction assay for analysis of this polymorphism in
