The rise of the Front National is only part of the problem
No full textThe rise of the Front National is only part of the problem Aurelien Mondon 7 December 2015 The ‘shock’ is not the rise of the Front National, but the failure of the system to bring forward a positive alternative. Marine Le Pen. Demotix/Francois Pauletto. All rights reserved. As with every recent election, France woke up this morning shocked and groggy. The Front National is front page material, somewhat of a theme recently. Right-wing Le Figaro and communist L’Humanité share the same ti..

France 2012: Sarkozy’s battle with the right hands Hollande the presidency
No full textFrancois Hollande has a tough challenge ahead, having won the French presidency. EPA/Guillaume Horcajuelo Socialist candidate Francois Hollande has won the French presidential election with 52% of the vote, ousting sitting president Nicolas Sarkozy. In hindsight, there have been few surprises in this campaign and election. Of course, many French people and commentators have been shocked or disappointed by the various twists and turns, but all that happened was predictable in a cold-headed ana..
Le Pen's attacks on Islam are no longer veiled
No full text"Anti-white racism" is big news in France. But while concern over the real or perceived bigotry faced by white people was previously limited to the National Front, a statement from Jean-Francois Cope, the secretary general of Sarkozy's UMP party has ushered this buzz-phrase into the mainstream. In his forthcoming book, Manifeste pour une droite décomplexée (Manifesto for an unabashed right-wing), Jean-François Copé declares he is willing to ‘break taboos’ and to denounce the growing ‘an..
Hollande declaring war will not rid Europe of terror
No full textFrancois Hollande has confirmed that the French government will take a hard stance in response to the attacks which took place in Paris on November 13. The Socialist president hinted more than once that his retaliation would even surpass in forcefulness that of Nicolas Sarkozy – his right-wing predecessor as president and opponent for the 2017 elections, despite the latter’s reputation for tough measures. French forces are already bombing Syria. In the aftermath of the attack, the early emoti..
Robotic Versus Laparoscopic Gastric Resection for Primary Gastrointestinal Stromal Tumors >5 cm: A Size-Matched and Location-Matched Comparison
No full textThis study compared robotic (RR) and laparoscopic resection (LR) for primary gastrointestinal stromal tumors (GISTs) of the stomach >5 cm. Twelve consecutive patients who underwent RR from 2012 to 2015 were matched for tumor size and location with 24 patients who underwent LR from 2000 to 2012. The median tumor size was 7.1 cm (range, 5.5 to 11.5). GISTs were resected by wedge resection (91.7%) or distal gastrectomy. The median RR operative time was longer than that of LR (162.5 vs. 130 min, respectively; P=0.004). Only 1 LR patient required conversion. The time to flatus and hospital stay were similar between groups. Overall, 3 patients developed minor postoperative complications that were medically treated. Mortality was nil. All resections were R0. No difference was observed in the incidence of recurrence. RR was significantly more expensive (+21.6%) than LR. RR appears to be safe and feasible for GISTs>5 cm, but is associated with longer operative times and greater costs

Each zip file in the dataset corresponds to 1 of these combinations and contains 12 files containing 1000 images.
The source galaxy redshift distribution corresponding to these maps is the full, non-tomographic redshift distribution n(z) from Fluri et. al.
The projected matter distribution was pixelised into images of size 128px x 128px, which correspond to 5deg x 5deg of the sky.
Eventually, the resulting dataset consists of 57 sets of 12'000 sky convergence maps for a total of samples.

Determinants of competitive balance across countries: insights from European men’s football first tiers, 2006-2018
Get PDFRationale/Purpose: The aim is to investigate the determinants of competitive balance (CB) across countries in European men’s club football. Determinants already tested previously in the literature include revenue sharing (proxied by countries’ income inequality), differences in drawing power, prize money, talent market and sports contest format. New determinants include climate, countries’ economic power, tradition, timing, number of clubs, financial regulation and international performance. Methodology: Regressions explaining CB are tested in the European men's football first tiers over the 2006–18 period. Findings: Results show that economic power and income inequality have a significant positive impact on CB; while climate (temperature), differences in drawing power, international performance and financial regulation have a significant negative impact. Practical implications: Results question whether international performance is a legitimate objective given its negative impact on CB. Research contribution: . Results enable to add new determinants explaining CB, namely countries’ economic power, financial regulation and international performance
