This study analyses employers‘ support for the introduction of industry-specifi c minimum wages as a cost-raising strategy in order to deter market entry. Using a unique data set consisting of 800 fi rms in the German service sector, we fi nd some evidence that high-productivity employers support minimum wages. We further show that minimum wage support is higher in industries and regions with l...

Free-energy barrier for entry of a charged polymer into a nanoscale channel by a driving electric field is studied theoretically and using molecular dynamics simulations. Dependence of the barrier height on the polymer length, the driving field strength, and the channel entrance geometry is investigated. Squeezing effect of the electric field on the polymer before its entry to the channel is ta...

An intact endothelial cell barrier maintains normal gas exchange in the lung, and inflammatory conditions result in barrier disruption that produces life-threatening hypoxemia. Activation of store-operated Ca2+ (SOC) entry increases the capillary filtration coefficient ( K f,c) in the isolated rat lung; however, activation of SOC entry does not promote permeability in cultured rat pulmonary mic...

Gram-negative bacteria can resist antibiotics by changing the permeability via their outer membrane. These have a complex cell envelope that incorporates an membrane separating periplasm from external environment. This contains many protein channels, also known as porins or nanopores, which mainly allow influx of hydrophilic compounds, including antibiotics. One probable way may possibly develo...

Wandering is a difficult-to-manage behavior problem for individuals with cognitive impairments that can jeopardize safety if an individual enters a hazardous area or becomes lost. This study investigated the effects of a cloth barrier on entry into an unsafe area. The cloth barrier reduced entry into the restricted area and had high treatment acceptability.

Nucleosomes uniquely positioned on high-affinity DNA sequences present a polar barrier to transcription by human and yeast RNA polymerase II (Pol II). In one transcriptional orientation, these nucleosomes provide a strong, factor- and salt-insensitive barrier at the entry into the H3/H4 tetramer that can be recapitulated without H2A/H2B dimers. The same nucleosomes transcribed in the opposite o...

We study a political economy model of entry barriers. Each period the policymaker determines whether to impose a high barrier to entry, and the special interest groups try to influence the policymaker’s decision. Entry is accompanied by creative destruction—when many new firms enter, old firms are more likely to be driven out of the market. Therefore the current incumbents (industry leaders) te...
