Breakup of the Doubly Magic 100Sn Core
- 2002
-
In: Physical Review C (Nuclear Physics). - 0556-2813. ; 66:1
-
Journal article (peer-reviewed)abstract
- Level schemes of Cd-99(48)51 and In-101(49)52 nuclei have been extended to high spin. The breakup of the doubly magic Sn-100 core has been observed. Large-scale shell model calculations based on realistic nucleon-nucleon interactions are in good agreement with the experimental data. These results provide a reliable basis to predict nuclear structure properties in Sn-100 and its neighbors. For example, the size of the N=50 shell gap and the energy of the first excited state in Sn-101 have been deduced.

Driving tests with older patients : Effect of unfamiliar versus familiar vehicle
- 2003
-
In: Transportation Research Part F. - 1369-8478 .- 1873-5517. ; 6:3, s. 163-173
-
Journal article (peer-reviewed)abstract
- The aim of the study was to study the effect, for older license holders, of taking a driving test with an unfamiliar vehicle, as compared to their own cars. The study population consisted of licensed patients 65-85 years referred to the Traffic Medicine Centre (TrMC), Huddinge University Hospital, for an evaluation of their medical and cognitive fitness to drive. In the clinical practice of TrMC, driving tests have been used since 1997, with inspectors from the Swedish National Road Administration (SNRA) acting as evaluators. Initially, patients were allowed to use their own cars. From the beginning of the year 2000, however, dual brakes were made mandatory and most evaluations were then made with SNRA cars. When comparing the outcomes of driving tests from the period prior to 2000 (n=96) and after 2000 (n=69), it was found that the number of drivers who failed the test increased by 16%. Also, those who passed the test after more than one trial decreased by 20%. The potential of the neuropsychological assessment to correctly classify drivers in outcome groups was considerably reduced in the period after 2000. These results support the view that, for older drivers with cognitive deterioration, the need to adapt to an unfamiliar vehicle represents a supplementary cognitive load that may compromise their driving ability and the validity of the assessment. A measure aimed only at increasing the safety of examiners and examinees thus had an unintended side-effect that is detrimental to older clinical populations. © 2003 Elsevier Ltd.

License suspension revisited: A 3-year follow-up study of older drivers
- 2003
-
In: JOURNAL OF APPLIED GERONTOLOGY. - : SAGE Publications. - 0733-4648 .- 1552-4523. ; 22:4, s. 427-444
-
Journal article (other academic/artistic)abstract
- This 3-year follow-up study addressed changes in health, cognitive functioning, and driving status among 37 older drivers and 37 individually matched controls. Initially, the study group had suspended driver’s licenses due to traffic violations. The in-person follow-up medical and neuropsychological examinations concerned 20 case participants and 22 controls. Mortality tended to be higher with case participants than with controls (p = .085), and there was more dementia or cognitive impairment with case participants (5/37) than with controls (0/37,p = .027). Initially, crash-involved case participants performed consistently worse on measures of cognitive functioning than did controls and noncrashed case participants and showed greater deterioration over time. Compared to controls, more crash-involved drivers had died (p = .019) or had stopped driving (p = .040). Because some older drivers with unsafe driving behavior may be in early phases of dementing processes or serious medical conditions, they should be medically and cognitively assessed.

The assessment of fitness to drive after a stroke : The Nordic Stroke Driver Screening Assessment
- 2003
-
In: Scandinavian Journal of Psychology. - : Wiley. - 0036-5564 .- 1467-9450. ; 44:1, s. 23-30
-
Journal article (peer-reviewed)abstract
- The British Stroke Driver Screening Assessment (SDSA) is a set of four simple cognitive tests to evaluate driving fitness in stroke patients. To evaluate its usefulness in a Scandinavian context, we adapted the tests and assessed a group of 97 stroke patients from Sweden and Norway, using a driving test as the criterion. When results were calculated according to the original method, based on a discriminant function, less than 70% of the participants were correctly classified. To improve the predictive potential, a new discriminant analysis was performed, using the scores of a subsample of 49 patients, and validated on the remaining 48 participants. In total, 78% of the patients were correctly classified, but specificity was superior to sensitivity. We conclude that the Nordic version of the SDSA is a useful instrument, provided that test scores are interpreted in a balanced manner, taking into account the possibility of compensatory traffic behavior.

Investigations of Neutron Deficient Nuclei Close to 100Sn with EUROBALL
- 2001
-
In: Acta Physica Polonica. Series B: Elementary Particle Physics, Nuclear Physics, Statistical Physics, Theory of Relativity, Field Theory. - 0587-4254 .- 1509-5770. ; 32, s. 999-1003
-
Journal article (peer-reviewed)abstract
- Excited states of nuclei in the vicinity of Sn-100 have been studied using: the EUROBALL detector array. Gamma-ray lines from Sn-103 have been identified for the first time, and a level scheme of low-lying excited states of Sn-103 has been established. New constraints on energies of single particle orbitals with respect to the Sn-100 core are obtained.
