Classical and Keynesian models of inequality and stagnation

This paper studies two formal models of long run growth with a medium-run distributive cycle, both of which feature causal links from the rise in inequality to a deterioration of long run macroeconomic performance. Both versions feature an endogenous income-capital ratio: one through the Keynesian notion of effective demand, the other building on induced bias in technical change. A key focus of the analysis is on the assumptions necessary in both frameworks to generate policy implications consistent with the observed decline of the labor share, the income-capital ratio, and labor productivity growth during the neoliberal era. Importantly, both theories: (a) provide space for mutually reinforcing pro-labor and pro-growth policies in the long run, although they differ in the mechanisms at play in these processes; (b) imply a potential tradeoff between pro-labor policies and growth on one hand, and long-run employment on the other; (c) are consistent with the evidence on the distributive cycle at business cycle frequency

Theoretical and Experimental Linguistic

Rational timing of combination therapy with tiotropium and formoterol in moderate and severe COPD.

AIM: To determine which timing of therapy with formoterol (FOR) and/or tiotropium (TIO) shows the greater and more continuous functional improvement during 24 h in patients with moderate to severe COPD. METHODS: In this randomised, blind, crossover study 80 patients with stable COPD (40 moderate and 40 severe) received 5 different bronchodilator 30-day treatments in a random order. Treatments (Tr) were: Tr1: TIO 18 microg once-daily (8 am); Tr2: TIO 18 microg (8 am) + FOR 12 microg (8 pm); Tr3: FOR 12 microg twice-daily (8 am and 8 pm); Tr4: TIO 18 microg (8 am) + FOR 12 microg twice-daily (8 am and 8 pm); Tr5: FOR 12 microg twice-daily (8 am and 8 pm) + TIO 18 microg (8 pm). Spirometries were performed during 24 h (13 steps) on Day1 and Day30. End-points were: gain of FEV(1) (DeltaFEV(1)) from baseline of the Day1 and Day30, AUC (Area Under Curve), Dyspnoea Index, and as-needed use of salbutamol. RESULTS: Sixty-eight patients completed all treatments. The greater and continuous daily functional improvement was showed during Tr4 and Tr5 (Day1 +135.8 mL and +119.1 mL; Day30 +160.2 mL, and +160.5 mL, respectively). Daily means of DeltaFEV(1) were significantly different between single-drug treatments and combination therapy. Dyspnoea was greater in single-drug treatments. Less use of rescue salbutamol was reported in Tr4 (0.80 puffs/die) and Tr5 (0.71 puffs/die). CONCLUSIONS: In patients with moderate to severe COPD, combination therapy with tiotropium administered in the morning (Tr4) was the most effective; in patients with prevailing night-symptoms, treatment with tiotropium in the evening (Tr5) reduced symptoms and use of salbutamol. Tr5 showed less variability of FEV(1) during the 24 h (CV=0.256). These results are relevant for opening new ways in clinical practice

SOLE Project – Demonstration of a Multistatic and Multiband Coherent Radar Network

The aim of the NATO-SPS SOLE project is demonstrating the feasibility and the high performance of a radar network thanks to photonics. Indeed, the coherence offered by photonics makes the proposed distributed radar system capable of an efficient implementation of MIMO processing and ISAR imaging, enhancing the performance in terms of resolution and precision. The advantage of a fully coherent, multistatic radar system here is experimentally proven by a 5-time cross-range resolution enhancement thanks to MIMO processing, and in an efficient focusing in ISAR imaging
