- Theories of coping and response shift have suggested that emotional adaptation is related to value changes, e.g. a deemphasized importance of lost life values and an enlargement of the scope of values. Perceived attainment and importance of 82 life values were examined in 65 patients with chronic obstructive pulmonary disease (COPD) and related to clinical and Health-Related Quality of Life (HRQL) measures. The life values covered 10 dimensions--harmony, positive relations, involvement, mobility, communication, knowledge, responsibility, comfort, religion and health. Forty-six of the patients were followed up after 1 year. The patients with COPD were compared with a healthy control group, a group of neurologically impaired and a non-disabled group representing the general population. Significant congruence was found between importance and attainment ratings in all groups (correlations from 0.44 to 0.53), suggesting that both impaired and healthy persons tend to perceive that they have what they find important in life. Congruence was significantly related to mood (correlations from 0.28 to 0.40), but not to functional status or clinical data. Compared to the healthy responders, the patients with COPD had significantly lower attainment ratings in health, mobility, involvement, but no differences were found for importance ratings. No evidence was found that they had replaced unattainable values with new available values, and no changes over time of perceived values were found. This suggests that patients with COPD do not seem to adapt by means of changing their value orientation.

Tidskriftsartikel (refereegranskat)abstract
- NANOSIL Network of Excellence [NANOSIL NoE web site < www.nanosil-noe.eu >], funded by the European Commission in the 7th Framework Programme (ICT-FP7, no 216171), aims at European scale integration of the excellent European research laboratories and their capabilities in order to strengthen scientific and technological excellence in the field of nanoelectronic materials and devices for terascale integrated circuits (ICs), and to disseminating the results in a wide scientific and industrial community. NANOSIL is exploring and assessing the science and technological aspects of nanodevices and operational regimes relevant to the n+4 technology node and beyond. It encompasses projects on nanoscale CMOS and beyond-CMOS. Innovative concepts, technologies and device architectures are proposed-with fabrication down to the finest features, and utilising a wide spectrum of advanced deposition and processing capabilities, extensive characterization and very rigorous device modeling. This work is carried out through a network of joint processing, characterization and modeling platforms. This critical interaction strengthens European integration in nanoelectronics and will speed up technological innovation for the nanoelectronics of the next two to three decades.

Möjligheter till lärande i matematik : Lärares problemformuleringar och dynamisk programvara
- 2006
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This thesis presents the first Swedish empirical evidence on how teachers employ a dynamic mathematical software when teaching mathematics in upper secondary school. The study examines: a) How teachers formulate mathematical problems? b) How they use the experience the students have gained? and c) What use they make of the software’s potential? These questions are examined through classroom observations followed up by discussions with the teachers.The study comprises three teachers and shows that they have very different mathematical experiences and teaching skills. A questionnaire was sent to the teachers prior to the classroom visits to collect relevant background information; e.g., the teachers were asked to describe their teacher training, their view of mathematics and of how a dynamic software could contribute to their teaching.The results show that the teachers’ ability to pose thought-provoking openended problems is the most important factor as it significantly influences what the students learn. The way a mathematical problem is formulated could, in conjunction with a dynamic software, actually limit the students’ achievement.However, this study confirms that it could also provide an opportunity for students to discover new mathematical relations, draw conclusions, generalise and formulate hypotheses. This could in turn lead to an in formally proving a mathematical relation. A conclusion of the study is that to be successful, teachers need a good mathematical background with a firm knowledge base and an understanding of the software’s potential, but they also need the skill to formulate open-ended problems that will enable their students to work successfully with a dynamic mathematical software.

A generalised methodology for oxide leakage current metric

Konferensbidrag (refereegranskat)abstract
- From calculations of semiconductor interfacecharge, oxide voltage and tunneling currents for MOSsystems with equivalent oxide thickness (EOT) in therange of 1 nm, rules are suggested for making itpossible to compare leakage quality of different oxideswith an accuracy of a factor 2 – 3 if the EOT is known.The standard procedure suggested gives considerablybetter accuracy than the commonly used method todetermine leakage at VFB+1V for n-type and VFB-1V forp-type substrates.
