Organized for parliament? Explaining the electoral success of radical right parties in post-communist Europe
Over the last three decades a great deal of research has been carried out in an attempt to explain the electoral performance of radical right parties in Europe. Most approaches concentrate on demand-side determinants and have some limitations. We compensate for these shortcomings and focus on the context of party competition and supply-side determinants (consistency of ideological discourse, functioning party propaganda, the continuity of the leader in office and strong party organization) to explain the electoral success of radical right parties in post-communist Europe. We conducted our analysis at party level in nine radical right parties in four countries from Central and Eastern Europe (Bulgaria, the Czech Republic, Hungary and Romania) between 1990 and 2014. The bivariate and multivariate (ordinal logistic regression) analyses draw on unique data collected from primary and secondary sources
"Brace Technology" Thematic Series - The ScoliOlogiCÂź ChĂȘneau lightâą brace in the treatment of scoliosis
<p>Abstract</p> <p>Background</p> <p>Bracing concepts in use today for the treatment of scoliosis include symmetric and asymmetric hard braces usually made of polyethylene (PE) and soft braces. The plaster cast method worldwide seems to be the most practiced technique for the construction of hard braces at the moment. CAD (Computer Aided Design) systems are available which allow brace adjustments without plaster. Another possibility is the use of the ScoliOlogiCâą off the shelf system enabling the Certified Prosthetist and Orthotist (CPO) to construct a light brace for scoliosis correction from a variety of pattern specific shells to be connected to an anterior and a posterior upright. This ChĂȘneau lightâą brace, developed according to the ChĂȘneau principles, promises a reduced impediment of quality of life in the brace. The correction effects of the first 81 patients (main diagnosis Adolescent Idiopathic Scoliosis (AIS) [n = 64] or Early Onset Scoliosis (EOS) [n = 15]), treated according to the principles of the ChĂȘneau lightâą brace have shown a satisfactory in-brace correction exceeding 50% of the initial Cobb angle.</p> <p>Brace description</p> <p>The ScoliOlogiC<sup>Âź </sup>off the shelf bracing system enables the CPO to construct a light brace for scoliosis correction from a variety of pattern specific shells to be connected to an anterior and a posterior upright. This brace, when finally adjusted is called ChĂȘneau lightâą brace. The advantage of this new bracing system is that the brace is available immediately, is easily adjustable and that it can also be easily modified. This avoids construction periods of sometimes more than 6 weeks, where the curve may drastically increase during periods of fast growth. The disadvantage of this bracing system is that there is a wide variability of possibilities to arrange the different shells during adjustment.</p> <p>Results</p> <p>The Cobb angle in the whole group was reduced by an average of 16,4°, which corresponds to a correction effect of 51%. The differences were highly significant in the T-test (T = 17,4; p < 0,001). The best correction effects achieved with ChĂȘneau braces reported in literature so far are about 40% in two different studies. The correction effect was highest in lumbar and thoracolumbar curve patterns (62%; n = 18). In thoracic scoliosis the correction effect was 36% (n = 41) and in double major curve patterns 50% (n = 22). The correction effect was affected in a slightly negative way due to age (r = -0,24; p = 0,014), negatively with the Risser stage (-0,29; p = 0,0096) and correlated negatively with the Cobb angle measured before treatment (r = -0,43; p < 0,0001).</p> <p>Conclusions</p> <p>The use of the ChĂȘneau lightâą brace leads to correction effects above average when compared to correction effects of other braces described in literature. The reduction of material seems to increase patient's comfort and reduces the stress patients may suffer from whilst in the brace.</p> <p>80% of the adolescent population of scoliosis patients can be braced with the ChĂȘneau lightâą brace. In certain patterns of curvature and in the younger population with an age of less than 11 years, other approaches have to be used, such as plaster based bracing or the application of CAD/CAM based orthoses.</p
Defect-free assembly of 2D clusters of more than 100 single-atom quantum systems
We demonstrate the defect-free assembly of versatile target patterns of up
111 neutral atoms, building on a 361-site subset of a micro-optical
architecture that readily provides thousands of sites for single-atom quantum
systems. By performing multiple assembly cycles in rapid succession, we
drastically increase achievable structure sizes and success probabilities. We
implement repeated target pattern reconstruction after atom loss and
deterministic transport of partial atom clusters necessary for distributing
entanglement in large-scale systems. This technique will propel assembled-atom
architectures beyond the threshold of quantum advantage and into a regime with
abundant applications in quantum sensing and metrology, Rydberg-state mediated
quantum simulation, and error-corrected quantum computation
