- Background: As part of preparation for a Swedish multicentre study, exploring sexual and married life in patients with myocardial infarction and their partners, a Swedish validated instrument was required. Aims:The aim of this pilot study was to evaluate the validity and reliability of a Swedish version of the Watts Sexual Function Questionnaire (WSFQ) among persons with a heart disease.Methods:A convenience sample of 79 persons (47 men and 32 women) living with a heart disease was recruited from the members of the National Association of Heart and Lung Patients. They completed a Swedish version of the WSFQ on two occasions. Results:Two separate factor analyses each revealed a two-factor structure on both occasions: “Sexual appetite” and “Sexual expectations ”with gender-neutral questions and “Sexual sensitiveness” and “Sexual ability” with gender-specific questions. Cronbach's alpha coefficients ranged from 0.48 to 0.86 and test – retest values for all but one question exceeded 0.70.Conclusions:The Swedish version of the WSFQ showed good validity and stability and acceptable internal homogeneity. Extended evaluations of the questionnaire are recommended.

- In this paper we describe the results from interviews with science teachers in lower secondary school. The teachers were asked what they wanted to achieve with laboratory work, what difficulties they experienced and if there were any differences between lab work in biology, chemistry and physics. The results show that the teachers wanted lab work to help the students develop their understanding, to make them interested and to develop their laboratory skills. Some of the teachers described lab work that included scientific inquiry but not, specifically, knowledge about how to systematically investigate phenomena in nature. Aspects of nature of science were rare. Lack of time to discuss with the students during lab work was seen as one difficulty which resulted in problems for students to linkobservables to scientific ideas. Laboratory exercises in chemistry were often regarded too abstract while lab work in physics and biology were much easier to link to everyday life.

- If an organism's juvenile and adult life stages inhabit different environments, certain traits may need to be independently adapted to each environment. In many organisms, a move to a different environment during ontogeny is accompanied by metamorphosis. In such organisms phenotypic induction early in ontogeny can affect later phenotypes. In laboratory experiments we first investigated correlations between body morphology and the locomotor performance traits expressed in different life stages of the common frog, Rana temporaria: swimming speed and acceleration in tadpoles; and jump-distance in froglets. We then tested for correlations between these performances across life stages. We also subjected tadpoles to unchanging or decreasing water levels to explore whether decreasing water levels might induce any carry-over effects. Body morphology and performance were correlated in tadpoles; morphology and performance were correlated in froglets: hence body shape and morphology affect performance within each life stage. However, performance was decoupled across life stages, as there was no correlation between performance in tadpoles and performance in froglets. While size did not influence tadpole performance, it was correlated with performance of the metamorphosed froglets. Experiencing decreasing water levels accelerated development time, which resulted in smaller tadpoles and froglets, i.e., a carry-over effect. Interestingly, decreasing water levels positively affected the performance of tadpoles, but negatively affected froglet performance. Our results suggest that performance does not necessarily have to be correlated between life stages. However, froglet performance is size dependent and carried over from the tadpole stage, suggesting that some important size-dependent characters cannot be decoupled via metamorphosis.
