Public support is usually a precondition for the adoption and successful implementation of costly policies. We argue that such support is easier to achieve with policy-packages that incorporate primary and ancillary measures. We specifically distinguish command-and-control and market-based measures as primary measures and argue that the former will usually garner more public support than the latter given the low-visibility tendency of costs associated with command-and-control measures. Nevertheless, if included in a policy-package, ancillary measures are likely to increase public support by reducing negative effects of primary measures. Based on a choice experiment with a representative sample of 2,034 Swiss citizens, we assessed these arguments with respect to political efforts to reduce vehicle emissions. The empirical analysis supported the argument that policy-packaging affects public support positively, particularly generating more support when ancillary measures are added. Lastly, we ultimately observe that command-and-control measures obtain more public support than market-based instruments.

The NASA/DLR Stratospheric Observatory for Infrared Astronomy (SOFIA), a 2.5-meter infrared telescope on board a Boeing 747-SP, will conduct 0.3 - 1,600 μm photometric, spectroscopic, and imaging observations from altitudes as high as 45,000 ft., where the average atmospheric transmission is greater than 80 percent. SOFIA's first light cameras and spectrometers, as well as future generations of instruments, will make important contributions to the characterization of the physical properties of exoplanets. Our analysis shows that optical and near-infrared photometric and spectrophotometric follow-up observations during planetary transits and eclipses will be feasible with SOFIA's instrumentation, in particular the HIPO-FLITECAM optical/NIR instruments. The airborne-based platform has unique advantages in comparison to ground- and space-based observatories in this field of research which we will outline here. Furthermore we will present two exemplary science cases, that will be conducted in SOFIA's cycle 1.

The freedom of movement of persons is one of the core tenets of the European Union. Immigration however is often seen as a cause for concern amongst native workers, as rising labour supply may threaten jobs and create downward pressure on wages. National politicians are increasingly under pressure to guard against it — in times of recession particularly. Despite this, there is evidence that highly-skilled migrant labour has the potential to raise competitiveness significantly and in theory this may feed into productivity. In this paper, we explore first the composition of inward migration to the EU and within the EU, concentrating specifically on the role of the highly-skilled and the extent to which migrants are overqualified within their jobs. We then analyse whether migrant workers affect productivity at the sectoral level. We find under-utilisation of skilled foreign labour and there is little evidence in general to suggest that migrants have raised productivity which may in part be attributable to over-qualification. However, we find robust evidence that migrants — particularly highly-skilled migrants — play a positive role in productivity developments in industries which are classified as ‘skill intensive’.

We use the case of the Eurasian lynx Lynx lynx in the Alps to discuss how to implement existing directives and recommendations, as well as how to integrate biological concepts, into practical conservation and wildlife management. Since 1995 the occurrence of lynx in the Alpine countries has been monitored and reported by the Status and Conservation of the Alpine Lynx Population expert group. Both the area of occupancy and the estimated number of individuals increased from 1995–1999 to 2000–2004. The estimated number of lynx is 120–150 across the Alps and the area of occupancy 27,800 km2, in six distinct sub-areas. In the highly fragmented Alpine habitat lynx populations expand slowly, even in situations of high local density and when suitable habitat is available. Thus, almost 40 years after the first reintroduction, < 20% of the Alps have been recolonized by lynx. In addition to biological and ecological factors, the persistent disagreements about the return of the lynx between conservationists and other land-users, including livestock breeders and hunters, and the political fragmentation of the Alps (with different regional priorities and large carnivore policies), has prevented the creation of a consensus regarding pan-Alpine conservation goals for the lynx and the implementation of conservation measures such as translocations and reintroductions. We discuss possible approaches in the light of new guidelines for population level management plans for large carnivores recently developed on behalf of the European Commission.

The impact of hysterectomy without oophorectomy and with no malignant purpose on body composition and postmenopausal weight gain was tested in 184 Viennese females aged between 47 and 57 years (mean 52·9). Hysterectomized women were significantly heavier than those who experienced a spontaneous menopause (controls). The amount of fat tissue, especially in the abdominal region, was significantly higher in hysterectomized women. Furthermore, they were reported to have experienced a significantly higher weight gain since menopause (9·1 versus 6·0 kg). No significant differences in bone mass were found. Psychological stress factors and hormonal changes following hysterectomy are discussed as possible causes of these differences.

The objective of this study was to evaluate growth and seed production of giant foxtail under different N sources (NO3 and NH4) and N fertilizer application rates. Nitrate and NH4 fertilizers plus nitrification inhibitor were applied at 56, 112, and 225 kg N ha−1 under field conditions, and in the greenhouse four N rates (1, 5, 10, and 25 mM N) were applied in three NO3: NH4 ratios (100 : 0, 50 : 50, 0 : 100). Growth of giant foxtail was affected by N rates under both greenhouse and field conditions. In 1993, abundant rainfall in May and June allowed a rapid and earlier uptake of N by giant foxtail, resulting in larger plants with greater N accumulation and higher numbers of heads and seeds than in 1994. Total dry weight increased with increasing N rates; however, seed production reached a maximum at approximately 150 kg N ha−1. Nitrogen translocation efficiency decreased with increasing N rates. Giant foxtail did not show any preference to N form; however, seed production was reduced when the high N rate was applied as NH4 compared to NO3. These results suggest that NH4 fertilizer applications with a long-term nitrification inhibitor could reduce the seed production of giant foxtail and its contribution to the soil seedbank for subsequent growing seasons.
