The purpose of the study was to investigate underreporting among persons of normal weight with a very high energy intake (El). The total energy expenditure (TEE) of 16 elite athletes (BMI 24 +/- 2 kg/m(2)) and 17 controls (BMI 23 3 kg/m2) was measured using the doubly-labeled water technique (DLW, 14d). El was estimated using 2 x 3-day dietary records. Underreporters were identified by BLACK'S cut-off (El:TEE < 0.76). 44% of athletes (El: 3584 824 kcal/d; TEE: 4621 1460 kcal/d) and 29% of controls (El: 2552 680 kcal/d; TEE: 3151 822 kcal/d) were identified as underreporters. TEE explains 52% of underreporting. In summary, a high energy intake seems to strongly predict underreporting. Prevalence and magnitude of underreporting increase with increasing energy intake.

Molecular methods are increasingly used in ecology, but studies generally do not report the detailed design of sample processing in the laboratory. This may strongly influence the interpretability of results if the laboratory procedures do not account for the confounding effects of unexpected laboratory events. We demonstrate this with a simple experiment where unexpected differences in laboratory processing of samples would have biased results if randomization in DNA extraction and PCR steps do not provide safeguards. We emphasize the need for proper experimental design and reporting of the laboratory phase of molecular ecology research to ensure the reliability and interpretability of results.

BT - the determinants of impartiality perceptions of the IMF and the World Bank JF - Review of international political economy N2 - The International Monetary Fund and the World Bank ascribe to impartiality in their mandates. At the same time, scholarship indicates that their decisions are disproportionately influenced by powerful member states. Impartiality is seen as crucial in determining International Organizations' (IOs) effectiveness and legitimacy in the literature. However, we know little about whether key interlocutors in national governments perceive the International Financial Institutions as biased actors who do the bidding for powerful member states or as impartial executors of policy. In order to better understand these perceptions, we surveyed high-level civil servants who are chiefly responsible for four policy areas from more than 100 countries. We found substantial variations in impartiality perceptions. What explains these variations? By developing an argument of selective awareness, we extend rationalist and ideational perspectives on IO impartiality to explain domestic perceptions. Using novel survey data, we test whether staffing underrepresentation, voting underrepresentation, alignment to the major shareholders and overlapping economic policy paradigms are associated with impartiality perceptions. We find substantial evidence that shared economic policy paradigms influence impartiality perceptions. The findings imply that by diversifying their ideational culture, IOs can increase the likelihood that domestic stakeholders view them as impartial.
