Renal Sympathetic Hyperactivity in Hypertension: True or False? To the Editor: Increased renal norepinephrine spillover, observed by using isotope-dilution method, is thought to indicate renal sympathetic hyperactivity and to play a crucial role in hypertension. However, SYMPLICITY HTN-3 (Renal Denervation in Patients With Uncontrolled Hypertension), the first randomized shamcontrolled trial, f...

I n order to have a successful regional planning policy, one needs to know exactly the effective factors on the growth of the provinces. Thus, determining and evaluating these growth rates are important for urban and regional planners. The main goal of this study is to determine the effective factors on the growth (population growth and per capita income growth) of Iran’s provinces. ...

UNLABELLED PET permits the quantification of myocardial blood flow, but is hampered by the limited spatial resolution of PET images. METHODS We evaluated two methods for the correction of resolution effects in PET perfusion 13NH3-ammonia images. In one model, the spillover and recovery coefficients are estimated in the kinetic modeling analysis. The new, second model uses an explicit delineat...

The main item of agreement between the ‘new’ and ‘old’ economic geography is the role of increasing returns in regional economic development. This provides a focal point for the model of this paper, which aims to highlight the existence of a ‘third way’ somewhere between the analysis provided by these two competing modes of explanation. Increasing returns are represented by the Verdoorn Law lin...

This paper proposes an extended Stochastic Impacts by Regression on Population, Affluence, and Technology (STIRPAT) model to investigate the factors driving industrial carbon emissions in China. In the first stage, a spatial Durbin model is applied to investigate the determinants of regional industrial carbon emissions. In the second stage, a geographically and temporally weighted regression is...

This paper presents a new perspective that there is a double-threshold effect in terms of the technology gap existing in the foreign direct investment (FDI) technology spillover process in different regional Chinese industrial sectors. In this paper, a double-threshold regression model was established to examine the relation between the threshold effect of the technology gap and technology spil...

Regional councils manage United States fisheries. Fishermen can participate in fisheries managed by multiple councils, and effort controls in one region could lead to effort leakage into another. Theoretical modeling demonstrates that positive, negative, and no leakage are possible. Using difference-in-differences, we test for leakage across regional boundaries for a catch share program in New ...

Knowledge spillover theory introduces specialized knowledge and human capital accumulation into the production function, breaks through limitations of traditional economic theory, illustrates continuous permanent source power growth. This article attempts to study “club phenomenon” uneven development China’s regional economy from perspective spillover, using Spatial Dubin Model (SDM) process pr...
