- The TiN/SiNx nanocomposite and nanolaminate systems are the archetype for super if not ultrahard materials. Yet, the nature of the SiNx tissue phase is debated. Here, we show by atomically resolved electron microscopy methods that SiNx is epitaxially stabilized in a NaCl structure on the adjacent TiN(001) surfaces. Additionally, electron energy loss spectroscopy, supported by first-principles density functional theory calculations infer that SiNx hosts Si vacancies.

Consumption of fruit, vegetables and soft drinks according to a FFQ and a food diary in 3- and 5 year old Swedish children

Konferensbidrag (refereegranskat)abstract
- Introduction: A validated food frequency questionnaire (FFQ) adapted to preschool ages is needed to evaluate a new program for primary prevention of childhood obesity. Methods: So far, in this ongoing validation study of 200 3-year olds and 200 5 year-olds (selected at random), food intake has been reported for 58 parent-offspring pairs. The parents (mostly mothers) reported their own and their child’s food intake in FFQs. In addition the child’s food intake was recorded prospectively in a food diary during two periods of four days duration each. Data on parental education, BMI, type of childcare, etc. were also collected. Results: The Spearman correlations (with 95 % CI) between FFQ and food-diary in children was 0.39 (0.15; 0.63) for number of meals per week containing vegetables, 0.70 (0.53; 0.87) for number of fruits per week and 0.66 (0.48; 0.82) for number of soft drinks per month. The Spearman correlation between intake according to the FFQ among parents and their children was 0.41 (0.15; 0.66) for number of meals/week containing vegetables, 0.22 (-0.03; 0.48) for number of fruits per week and 0.44 (0.22; 0.66) for number of soft drinks per month. Conclusion: For the young children our preliminary results show associations of modest size between the two methods for meals with vegetables and stronger associations for fruits and soft drinks. The association between parents’ and children’s intake according to FFQ was weak for fruit, moderate for vegetables and fairly strong for soft drink. Results based on the full dataset will be presented.

- BACKGROUND: Eating behavior may be implicated in the increasing prevalence of overweight and obesity, presumably in relation to easy access to energy-dense and highly palatable foods. OBJECTIVE: The aim of the present study was to disentangle genetic and environmental influences on eating behavior in a population-based cohort of male twins. DESIGN: The study included 326 dizygotic and 456 monozygotic male twin pairs aged 23-29 y from Sweden. The revised 21-item version of the Three-Factor Eating Questionnaire (TFEQ-R21) was used to assess eating behavior. This validated instrument consists of 3 dimensions: cognitive restraint, emotional eating, and uncontrolled eating. Structural equation modeling was used to estimate the heritability of eating behavior. RESULTS: Cognitive restraint was the only TFEQ-R21 scale that significantly correlated with BMI (r = 0.39, P < 0.0001). The best-fitted models gave a heritability of 59% (95% CI: 52%, 66%) for cognitive restraint, 60% (95% CI: 52%, 67%) for emotional eating, and 45% (95% CI: 36%, 53%) for uncontrolled eating. CONCLUSIONS: These results show the great importance of genetic factors in the eating behavior of a large, unselected population of young adult male twins. Nonshared environmental factors were also important, whereas shared environmental factors did not contribute to eating behavior.

On the identification of the unrestricted Thurstonian model for ranking data
-
Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- The identification issues of the unrestricted Thurstonian model for ranking data is the focus of the current paper. Within the Thurstonian framework, each object among those to be ranked is associated with a latent continuous variable, often interpreted as the utility of the object. The unrestricted Thurstonian model, due to the discrete and comparative nature of ranking data, faces more serious identification problems than the indeterminacy of the latent scale origin and unit. Most researchers resort to the study of the unrestricted model referring to the differences of the object utilities but then the inference on object utilities becomes tricky. Maydeu-Olivares and Böckenholt (2005) suggest a strategy to overcome the identification problem of the unrestricted model referring to object utilities but this requires many extra identification constraints, additional to the ones needed for defining the scale origin and unit. In the current paper, we study the general applicability of the suggested identification approach. Our simulation study indicates that the estimates obtained can be seriously biased with relatively large mean squared errors (MSE) when the extra constraints deviate from the true values of the parameters. Besides, the bias and MSE do not seem to decrease with increase in the sample size, and the effect of the constraints is not uniform on all estimated parameters.
