In this paper, it is argued that the observed high positive correlation between national savings and investment which is found in the data can in part be explained by shocks to monetary policy. This hypothesis, which is established by reviewing some empirical findings, is tested in a two-country DSGE-model framework in the tradition of the New Open Economy Macroeconomics. The simulation results obtained support the idea that shocks to monetary policy might contribute to the explanation of the Feldstein-Horioka puzzle.

How does an unexpected domestic monetary expansion affect the foreign economy? Does it induce an increase or a decline in foreign production? In the traditional two-country Mundell-Fleming model, monetary policy has beggar-thy-neighbor effects. Yet, empirical evidence from VARs indicates that U.S. monetary policy has positive international transmission effects on both foreign (non-U.S. G-7) output and aggregate demand. In this paper, I will show that a two-country dynamic general equilibrium model with sticky prices can account for these stylized facts if we allow for international asymmetries in the price-setting behavior of firms. If U.S. firms set export prices in their own currency only (producer-currency pricing), whereas producers in the rest of the world price their exports to the U.S. in the local currency of the export market (local-currency pricing), a U.S. monetary expansion is found to increase output and aggregate demand abroad.

This article investigates how land users perceive laws restricting deforestation and forest degradation, notably Brazil's National Forest Code, and how legal meaning emerges as place specific to influence their legal compliance. Interviews were held with land users in Acre state, a municipality with high rates of deforestation located in the forest frontier of the Brazilian Amazon. Critical legal geography was applied as a theoretical framework to investigate the ways in which legal meaning emerges in and through that social context. This research finds that non-compliance is associated with pervasive conditions of social stress combined with lived experiences of contradictory legal processes, including shifting legal discourses and inconsistent local law enforcement. In such social contexts, local legal meaning associates forest conservation laws with socio-economic and legal inequality and the reinforcement of structures of social exclusion.

Ziel dieser Arbeit ist es, die Nutzung von AMS in Kommunen zu evaluieren. Dazu soll der Ist-Stand des kommunalen Anliegenmanagements dargestellt und bewertet werden. Untersucht werden die Gründe für die Verwendung eines AMS, der Bearbeitungsprozess sowie positive und negative Erfahrungen der Kommunen mit der Verwendung von AMS.

Activities of the naturally occurring radium nuclides Ra-228, Ra-226, Ra-224 and Ra-223 were determined in waters of the open German Bight and adjacent nearshore areas in the North Sea, in order to explore the potential use of radium isotopes as natural tracers of land-ocean interaction in an environment characterised by extensive tidal flats, as well as riverine and groundwater influx. Data collected at various tidal phases from the Weser Estuary (Ra-228: 46.3 +/- 4.6; Ra-226: 17.1 +/- 1.1; Ra-224: 26.1 +/- 8.2 to 36.5 +/- 6.1; Ra-223: 1.8 +/- 0.1 to 4.0 +/- 0.4), tidal flats near Sahlenburg (Ra-228: 39.3 +/- 3.8 to 46.0 +/- 4.5; Ra-226: 15.5 +/- 1.5 to 16.5 +/- 1.7; Ra-224: 34.3 +/- 2.2 to 85.3 +/- 6.3; Ra-223: 3.6 +/- 0.5 to 8.0 +/- 1.2), freshwater seeps on tidal flats near Sahlenburg (Ra-228: 42.1 +/- 4.1; Ra-226: 21.3 +/- 2.2; Ra-224: 5.1 +/- 0.9; Ra-223: 2.6 +/- 1.3) and also in permanently inundated parts of the North Sea (Ra-228: 23.0 +/- 2.3 to 28.2 +/- 2.8; Ra-226: 8.2 +/- 0.8 to 11.8 +/- 1.2; Ra-224: 3.1 +/- 1.0 to 10.1 +/- 0.9; Ra-223: 0.1 +/- 0.02 to 0.9 +/- 0.05; units: disintegrations per minute per 100 kg water sample) reveal that, except for the fresh groundwater, the potential end-members of nearshore water mass mixing have quite similar radium signatures, excluding a simple discrimination between the sources. However, the decreasing activities of the short-lived Ra-224 and Ra-223 isotopes recorded towards the island of Helgoland in the central German Bight show a potential to constrain fluxes of land-derived material to the open North Sea. The largest source for all radium isotopes is generally found on the vast tidal flats and in the Weser Estuary. Future work could meaningfully combine this so-called radium quartet approach with investigations of radon activity. Indeed, preliminary data from a tidal flat site with fresh groundwater seepage reveal a Rn-222 signal that is clearly lower in seawater. ; government of the Brussels-Capital Region; Netherlands Organization for Scientific Research ...

Background: Comprehensive proteomics profiling may offer new insights into the dysregulated metabolic milieu of type 2 diabetes, and in the future, serve as a useful tool for personalized medicine. This calls for a better understanding of circulating protein patterns at the early stage of type 2 diabetes as well as the dynamics of protein patterns during changes in metabolic status. Methods: To elucidate the systemic alterations in early-stage diabetes and to investigate the effects on the proteome during metabolic improvement, we measured 974 circulating proteins in 52 newly diagnosed, treatment-naïve type 2 diabetes subjects at baseline and after 1 and 3 months of guideline-based diabetes treatment, while comparing their protein profiles to that of 94 subjects without diabetes. Findings: Early stage type 2 diabetes was associated with distinct protein patterns, reflecting key metabolic syndrome features including insulin resistance, adiposity, hyperglycemia and liver steatosis. The protein profiles at baseline were attenuated during guideline-based diabetes treatment and several plasma proteins associated with metformin medication independently of metabolic variables, such as circulating EPCAM. Interpretation: The results advance our knowledge about the biochemical manifestations of type 2 diabetes and suggest that comprehensive protein profiling may serve as a useful tool for metabolic phenotyping and for elucidating the biological effects of diabetes treatments.
