Tokamak edge-SOL turbulence in H-mode conditions simulated with a global, electromagnetic, transcollisional drift-fluid model

Nuclear Fusion
The design of commercially feasible magnetic confinement fusion reactors strongly relies on the reduced turbulent transport in the plasma edge during operation in the high confinement mode (H-mode).

Inter-machine validation study of neoclassical transport modelling in medium- to high-density stellarator-heliotron plasmas

, 2013
A comparative study of energy transport for medium- to high-density discharges in the stellarator-heliotrons TJ-II, W7-AS and LHD is carried out.

Does Continuous Disclosure Improve Investment Efficiency? Evidence from a Unique Regulatory Setting

Abacus, EarlyView.
We examine the association between continuous disclosure and investment efficiency within the context of Australia's unique regulatory setting for continuous disclosure. Based on 8,527 firm‐year observations, we find that continuous disclosure is positively associated with investment efficiency and helps to mitigate both over‐investment and under ...

Radio frequency induced and neoclassical asymmetries and their effects on turbulent impurity transport in a tokamak

, 2013
Poloidal asymmetries in the impurity density can be generated by radio frequency heating in the core and by neoclassical effects in the edge of tokamak plasmas.

Turbulence-reduced high-performance scenarios in Wendelstein 7-X

Nuclear Fusion
In the Wendelstein 7-X (W7-X) stellarator, turbulence is the dominant transport mechanism in most discharges. This leads to a ‘clamping’ of ion temperature over a wide range of heating power, predominantly flat density profiles where hollow profiles ...

Private Land Ownership: Tax or Socialize?

The American Journal of Economics and Sociology, EarlyView.
ABSTRACT This study compares the land reform concepts of Henry George and Silvio Gesell, both of whom rejected private appropriation of land rent as unjust. While George proposed to “hollow out” private land ownership through a comprehensive land value tax, Gesell aimed at full socialization of land combined with lease auctions and compensation of ...

Theories of Interest and Their Relation to the Gesell–Keynes Theory

The American Journal of Economics and Sociology, EarlyView.
ABSTRACT We consider theories of interest as they relate to what we will call the Gesell‐Keynes (GK) theory which is essentially a real theory of capital accumulation with a monetary constraint that arises because of a liquidity return on holding money.

High-Z impurity neoclassical transport in the tokamak plasmas due to the single-null divertor configuration

Nuclear Fusion
A new mechanism for the high-Z impurity neoclassical particle transport in the tokamak plasmas due to the single-null divertor configuration is discovered for the first time.

Henry George and Silvio Gesell: The Odd Couple

The American Journal of Economics and Sociology, EarlyView.
ABSTRACT Henry George (1839–1897) and Silvio Gesell (1862–1930) developed distinct yet overlapping economic reform agendas. Both advocated land reform, free markets, and rejection of protectionism, but differed sharply on money, interest, and taxation.

The institutional paradox of a substantivist conception of the economy in public policy: Insights from public procurement for solidarity economy in Ecuador

Annals of Public and Cooperative Economics, EarlyView.
Abstract Ecuador's 2008 Constitution advanced an ambitious substantive economic vision through Buen Vivir (Good Living), recognizing a plural economy which encompasses private, public and solidarity economy (SE) sectors. This paper aims to analyze public procurement programs in Ecuador, one of the flagship Buen Vivir policies for SE promotion.
