Regional wage convergence in Spain : 1850-1930 [PDF]

open access: yes, 2002
Real wages PPP adjusted are used to analyse labour market integration in Spain. In contrast to earlier research analysing migration and nominal wages rates, our research seems to indicate that a well-integrated labour market had emerged in Spain by 1914 ...

Phase Fraction Modulation Enhances Li+/Na+ Diffusion Disparity in Spent LiFePO4 Cathodes for Efficient Lithium Extraction from Brine

open access: yesAdvanced Science, EarlyView.
A direct cascaded utilization strategy for spent LiFePO4 batteries efficiently extracts lithium from brine, embodying the “urban mining” concept. Phase fraction modulation revealed its significant impact on local bond lengths of crystal structure and the Li/Na diffusion energy barrier, identifying the best material (Li0.19FePO4) for lithium extraction.

Transactions Costs and Internal Labor Markets [PDF]

open access: yes
The concept of transactions costs used by Coase in "The Nature of the Firm" is applied to the internal labor market of an organization. Under joint production it is shown that the number of transaction-specific prices necessary to decentralize labor ...

Wireless, Adaptable and Fully Implantable Battery‐powered Devices for Optical Stimulation of the Spinal Cord in Small Rodents

open access: yesAdvanced Science, EarlyView.
Current technologies for spinal cord optogenetic stimulation rely on external power sources and face reliability constraints in freely behaving animals. Here, a fully implantable, battery‐powered optoelectronic device is introduced, enabling operation in any selected environment with wireless recharging for months‐long stimulation.

On the Role of Preprocessing and Memristor Dynamics in Reservoir Computing for Image Classification

open access: yesAdvanced Electronic Materials, EarlyView.
ABSTRACT Reservoir computing (RC) is an emerging recurrent neural network architecture that has attracted growing attention for its low training cost and modest hardware requirements. Memristor‐based circuits are particularly promising for RC, as their intrinsic dynamics can reduce network size and parameter overhead in tasks such as time‐series ...

The internal economics of a university - evidence from personnel data [PDF]

open access: yes
Based on a rich personnel data set of a large university we .nd strong evidence for the existence of an internal labor market. First, the lowest academic rank is a strong port of entry and the highest rank is a port of exit.

How can European competition law address market distortions caused by state-owned enterprises? Bruegel Policy Contribution Issue No. 18 | December 2019 [PDF]

open access: yes, 2019
This Policy Contribution assesses whether European competition law could be applied more directly to state-owned enterprises that create an unlevel playing field in Europe because of the support they receive from their home governments.
