Introgression from extinct species facilitates adaptation to its vacated niche
No full textAnthropogenic disturbances of ecosystems are causing a loss of biodiversity at an
unprecedented rate. Species extinctions often leave ecological niches underutilized, and
their colonization by other species may require new adaptation. In Lake Constance, an
endemic profundal whitefish species went extinct during a period of anthropogenic
eutrophication. In the process of extinction, the deep-water species hybridized with
three surviving whitefish species of Lake Constance, resulting in introgression of genetic
variation that is potentially adaptive in deep-water habitats. Here, we sampled a water
depth gradient across a known spawning ground of one of these surviving species,
Coregonus macrophthalmus, and caught spawning individuals in greater depths (down
to 90m) than historically recorded. We sequenced a total of 96 whole genomes, 11-17 for
each of six different spawning depth populations (4m, 12m, 20m, 40m, 60m, and 90m),
to document genomic intraspecific differentiation along a water depth gradient. We
identified 52 genomic regions that are potentially under divergent selection between the
deepest (90m) and all shallower (4-60m) spawning habitats. At 12 (23.1%) of these 52
loci, the allele frequency pattern across historical and contemporary populations
suggests that introgression from the extinct species potentially facilitates ongoing
adaptation to deep water. Our results are consistent with the syngameon hypothesis,
proposing that hybridization between members of an adaptive radiation can promote
further niche expansion and diversification. Furthermore, our findings demonstrate that
introgression from extinct into extant species can be a source of evolvability enabling
rapid adaptation to environmental change and may contribute to the ecological recovery
of ecosystem functions after extinctions
Short‐term forecasts of euro area GDP growth
No full textThis paper evaluates models that exploit timely monthly releases to compute early estimates of current quarter GDP (now-casting) in the euro area. We compare traditional methods used at institutions with a new method proposed by Giannone et al. The method consists in bridging quarterly GDP with monthly data via a regression on factors extracted from a large panel of monthly series with different publication lags. We show that bridging via factors produces more accurate estimates than traditional bridge equations. We also show that survey data and other 'soft' information are valuable for now-casting. © 2011 The Author(s).

Sense-B-noise: an enigmatic cause for inappropriate shocks in subcutaneous implantable cardioverter defibrillators.
No full textAIMS
Subcutaneous implantable cardioverter defibrillators (S-ICDs) are well established. However, inappropriate shocks (IAS) remain a source of concern since S-ICDs offer very limited troubleshooting options. In our multicentre case series, we describe several patients who experienced IAS due to a previously unknown S-ICD system issue.
METHODS AND RESULTS
We observed six patients suffering from this novel IAS entity. The IAS occurred exclusively in primary or alternate S-ICD sensing vector configuration (therefore called 'Sense-B-noise'). IAS were caused by non-physiologic oversensing episodes characterized by intermittent signal saturation, diminished QRS amplitudes, and disappearance of the artefacts after the IAS. Noise/oversensing could not be provoked by manipulation, X-ray did not show evidence for lead/header issues and impedance measurements were within normal limits. The pooled experience of our centres implies that up to ∼5% of S-ICDs may be affected. The underlying root cause was discussed extensively with the manufacturer but remains unknown and is under further investigation.
CONCLUSION
Sense-B-noise is a novel cause for IAS due to non-physiologic signal oversensing, arising from a previously unknown S-ICD system issue. Sense-B-noise may be suspected if episodes of signal saturation in primary or alternate vector configuration are present, oversensing cannot be provoked, and X-ray and electrical measurements appear normal. The issue can be resolved by reprogramming the device to secondary sensing vector
Dynamic inefficiency in an overlapping generations economy with production
No full textReichlin [Equilibrium cycles in an overlapping generations economy with production, J. Econ. Theory 40 (1986) 89–102] has shown in an OLG model with productive capital that whenever the steady state is locally indeterminate and undergoes a Hopf bifurcation, it is Pareto-optimal. While these results were established under the assumption of Leontief technology, the author has partially extended them to show that the Hopf\ud
bifurcation is robust with respect to the introduction of capital–labor substitution. In this note, we prove that the Pareto-optimality of the steady state does not extend to technologies with capital–labor substitution.\ud
When the steady state is a sink or undergoes a Hopf bifurcation, it is characterized by over-accumulation with respect to the Golden Rule—the interest rate is negative—hence not Pareto-optimal. Most importantly, it follows that stabilization policies targeting the steady state leave room for welfare losses associated with productive inefficiency, apart from the very special case of Leontief technology
An alternative measure of inflation
No full textThe author proposes an alternative measure of inflation that captures the intuition behind the use of "core" measures. Inflation is modeled as an unobserved factor affecting the components of an aggregate price index (including food and energy). The common component, estimated using Kalman filtering, resembles usual measures of core inflation; its extrapolation can be used to improve performance in forecasting core inflation.Inflation (Finance) ; Monetary policy
Driving Forces of Inflation in New EU Countries (in English)
No full textDriving forces of inflation in the eight new EU member states from Central and Eastern Europe are analyzed using the generalized dynamic-factor model (GDFM) developed by Forni et al. the impact of various macroeconomic variables on inflation is estimated by regressing the GDFM idiosyncratic component on these variables; the importance of second-round and indirect effects from energy shocks is assessed using a bivariate VAR. The author´s results suggest that, first, a significant part of inflation in the new members is driven by common factors, and, second, common component inflation is a better estimator of underlying inflation than a core inflation measure (i.e., headline inflation, excluding energy, food, alcohol, and tobacco).generalized dynamic-factor model, idiosyncratic components, inflation
Decomposing U.S. Nominal Interest Rates into Expected Inflation and Ex Ante Real Interest Rates Using Structural VAR Methodology
No full textIn this paper, the author uses structural vector autoregression methodology to decompose U.S. nominal interest rates into an expected inflation component and an ex ante real interest rate component. He identifies inflation expectations and ex ante real interest rate shocks by assuming that nominal interest rates and inflation expectations move one-for-one in the long-run - they are cointegrated (1,1) - and that the real interest rate is stationary. He finds that changes in inflation expectations and in the ex ante real interest rate are both important in explaining fluctuations in the U.S. 1-year and 10-year government bond rates. The author also finds that, while the increase in the 1-year and the 10-year bond rates in the 1970s and the early 1980s mainly reflects higher inflation expectations, changes in ex ante real interest rates appear to account for most of the fluctuations in these rates in 1994 and in the first half of 1995.
