Within the approaches that have been applied to assess the impact of public capital on economic growth, this paper estimates the dynamic effects of public infrastructures using a structural vector autoregressive (SVAR) methodology for the Spanish regions. From a methodological point of view, our work contains different innovative features with respect to the previous studies using VAR models. T...

The main objective of this study is to analyze spillover fluctuations between inflation fluctuation and (un)employment fluctuation in relation to agriculture, industry and services sectors of Iran. In line with this, PANEL in Mean-MGARCH model has been used concerning Iran’s agriculture, industry and services sectors over the period of time from spring 2002 to winter 2016. The results show that...

Relying on the M&A transaction-level dataset and adopting a more region-specific approach with focus industry-region pairs, this paper examines how cross-border acquisitions have an effect, in terms of technological spillover collaboration, European industrial clusters. Adopting industry-regions pairs approach, study is based quantitative analysis 3039 regional clusters belonging to 262 regions...

BACKGROUND Increased sympathetic nerve activity may contribute to the progression of renovascular hypertension. Because previous results have been inconclusive, we investigated whether renovascular hypertensives show increased total and regional sympathetic nerve activity. METHODS AND RESULTS Sixty-five patients underwent renal angiography and measurements of plasma renin activity and angiote...

This article focuses on entrepreneurship in economic geography and aims at a systematic investigation of regional variation in knowledge-based entrepreneurial activity. We develop and test a three-phase structural model for regional systems of entrepreneurship after introducing a systems approach to entrepreneurship. The model is built upon the absorptive capacity theory of knowledge spillover ...

We evaluated whole body and regional (subcutaneous abdominal adipose tissue and forearm) norepinephrine (NE) kinetics in seven lean (body mass index 21.3 ± 0.5 kg/m2) and six upper body obese (body mass index 36.4 ± 0.4 kg/m2) women who were matched on fat-free mass. NE kinetics were determined by infusing [3H]NE and obtaining blood samples from a radial artery, a deep forearm vein draining mos...

The analysis of plasma kinetics of the sympathetic neurotransmitter norepinephrine can be used to estimate sympathetic nervous "activity" (integrated nerve firing rate) for the body as a whole and for individual organs. In 12 patients with cardiac failure (left ventricular ejection fraction 10% to 39%), the mean arterial plasma norepinephrine concentration was 557 +/- 68 pg/ml (mean +/- SE) com...

Sympathetic activation produced by various stimuli, eg, mental stress or handgrip, evokes regional vascular responses that are often nonhomogeneous. This phenomenon is believed to be the consequence of the recruitment of differential central neural pathways or of a sympathetically mediated vasodilation. The purpose of this study was to determine whether a similar heterogeneous response occurs w...
