Selected conceptual issues in border studies

The paper is based on first results of the EUBORDERSCAPES project supported by the 7th European Framework Programme and revisits a number of major themes and concepts that have been important for the development of border studies in recent years. It also investigates emerging research perspectives that appear to be important drivers of conceptual change from the perspective of human geography. The authors stress that the present state of debate indicate that contemporary border studies question the rationales behind everyday border-making by understanding borders as institutions, processes and symbols. A particular attention is paid to the process of reconfiguring state borders in terms of territorial control, security and sovereignty and to the nexus between everyday life-worlds, power relations and constructions of social borders.L’article se fonde sur les premiers résultats du projet EUBORDERSCAPES soutenu par le 7ème Programme-cadre européen, et est consacré à plusieurs des principaux thèmes et concepts importants dans le développement des études sur les frontières au cours des dernières années. Ce faisant, il aborde des perspectives de recherche émergentes de nature à susciter un changement conceptuel dans l’optique de la géographie humaine. D’après l’état de la littérature, les auteurs soulignent que les travaux actuels sur les frontières s’intéressent aux raisons présidant à la production de la frontière à travers les pratiques quotidiennes des populations, en comprenant les frontières à la fois comme institutions, processus et symboles. Une attention particulière est portée au processus de la reconfiguration des frontières étatiques en termes de contrôle territorial, de sécurité et de souveraineté, ainsi qu’aux interrelations entre la sphère de la vie quotidienne, celle du pouvoir et celle de la construction des frontières sociales

La nuova Russia. Dibattito culturale e modello di società in costruzione

Una radiografia del dibattito culturale della Russia che illustra i tanti problemi con cui si deve confrontare la costruzione di una nuova società. Modernizzazione, tradizionalismo, nuovo corporativismo, privatizzazioni, nazionalismo e religione sono solo alcuni degli elementi che compongono un quadro ricco di conflittualità e foriero di grandi trasformazioni.- Indice #5- Radiografia del dibattito culturale: modernizzazione e tradizionalismo nello scontro tra gli “addetti ai lavori”, Ilja Levin #9- Partiti e società: evoluzione e prospettive della differenziazione politica ed ideologica nella Russia postsovietica, Kirill Kholodkovski #29- Dal “collettivismo” all’individualismo: l’uomo nella società deistituzionalizzata, Guerman Diliguenski #45- Gruppi direttivi regionali: trasformazione dei meccanismi organizzativi e relazionali del potere, Mikhail Afanasjev #63- L’”oligarchia” e la crisi in atto nel postcomunismo russo, Alexeij Zudin #81- Il nuovo corporativismo russo all’interno del contesto globale: il ruolo in via di cambiamento dell’élite settoriale, Sergei Peregudov #107- La formazione di nuovi mercati e lo Stato nella Russia postcomunista, Vadim Radaev #133- Stabilizzazione macroeconomica e mutamenti strutturali nell’economia nazionale russa: deindustrializzazione o sfondamento verso una società postindustriale?, Vladimir Mau e Irina Starodubrovskaja #163- Dopo la privatizzazione: alla ricerca di un modello ottimale di società, Viktor Studentsov #187- Fondamenta e principi dello Stato accentratore in Russia, Igor Pantin #217- Nazionalismo liberale o idea imperiale?

Design, Performance, and Calibration of CMS Hadron Endcap Calorimeters

Detailed measurements have been made with the CMS hadron calorimeter endcaps (HE) in response to beams of muons, electrons, and pions. Readout of HE with custom electronics and hybrid photodiodes (HPDs) shows no change of performance compared to readout with commercial electronics and photomultipliers. When combined with lead-tungstenate crystals, an energy resolution of 8\% is achieved with 300 GeV/c pions. A laser calibration system is used to set the timing and monitor operation of the complete electronics chain. Data taken with radioactive sources in comparison with test beam pions provides an absolute initial calibration of HE to approximately 4\% to 5\%

Energy Response and Longitudinal Shower Profiles Measured in CMS HCAL and Comparison With Geant4

The response of the CMS combined electromagnetic and hadron calorimeter to beams of pions with momenta in the range 5-300 GeV/c has been measured in the H2 test beam at CERN. The raw response with the electromagnetic compartment calibrated to electrons and the hadron compartment calibrated to 300 GeV pions may be represented by sigma = (1.2) sqrt{E} oplus (0.095) E. The fraction of energy visible in the calorimeter ranges from 0.72 at 5 GeV to 0.95 at 300 GeV, indicating a substantial nonlinearity. The intrinsic electron to hadron ratios are fit as a function of energy and found to be in the range 1.3-2.7 for the electromagnetic compartment and 1.4-1.8 for the hadronic compartment. The fits are used to correct the non-linearity of the e pi response to 5% over the entire measured range resulting in a substantially improved resolution at low energy. Longitudinal shower profile have been measured in detail and compared to Geant4 models, LHEP-3.7 and QGSP-2.8. At energies below 30 GeV, the data, LHEP and QGSP are in agreement. Above 30 GeV, LHEP gives a more accurate simulation of the longitudinal shower profile

Synchronization and Timing in CMS HCAL

The synchronization and timing of the hadron calorimeter (HCAL) for the Compact Muon Solenoid has been extensively studied with test beams at CERN during the period 2003-4, including runs with 40 MHz structured beam. The relative phases of the signals from different calorimeter segments are timed to 1 ns accuracy using a laser and equalized using programmable delay settings in the front-end electronics. The beam was used to verify the timing and to map out the entire range of pulse shapes over the 25 ns interval between beam crossings. These data were used to make detailed measurements of energy-dependent time slewing effects and to tune the electronics for optimal performance

Design, Performance, and Calibration of CMS Hadron-Barrel Calorimeter Wedges

Extensive measurements have been made with pions, electrons and muons on four production wedges of the Compact Muon Solenoid (CMS) hadron barrel (HB) calorimeter in the H2 beam line at CERN with particle momenta varying from 20 to 300 GeV/c. Data were taken both with and without a prototype electromagnetic lead tungstate crystal calorimeter (EB) in front of the hadron calorimeter. The time structure of the events was measured with the full chain of preproduction front-end electronics running at 34 MHz. Moving-wire radioactive source data were also collected for all scintillator layers in the HB. These measurements set the absolute calibration of the HB prior to first pp collisions to approximately 4%

Design, Performance and Calibration of the CMS Forward Calorimeter Wedges

We report on the test beam results and calibration methods using charged particles of the CMS Forward Calorimeter (HF). The HF calorimeter covers a large pseudorapidity region (3\l |\eta| \le 5), and is essential for large number of physics channels with missing transverse energy. It is also expected to play a prominent role in the measurement of forward tagging jets in weak boson fusion channels. The HF calorimeter is based on steel absorber with embedded fused-silica-core optical fibers where Cherenkov radiation forms the basis of signal generation. Thus, the detector is essentially sensitive only to the electromagnetic shower core and is highly non-compensating (e/h \approx 5). This feature is also manifest in narrow and relatively short showers compared to similar calorimeters based on ionization. The choice of fused-silica optical fibers as active material is dictated by its exceptional radiation hardness. The electromagnetic energy resolution is dominated by photoelectron statistics and can be expressed in the customary form as a/\sqrt{E} + b. The stochastic term a is 198% and the constant term b is 9%. The hadronic energy resolution is largely determined by the fluctuations in the neutral pion production in showers, and when it is expressed as in the electromagnetic case, a = 280% and b = 11%

Design, Performance, and Calibration of the CMS Hadron-Outer Calorimeter

The CMS hadron calorimeter is a sampling calorimeter with brass absorber and plastic scintillator tiles with wavelength shifting fibres for carrying the light to the readout device. The barrel hadron calorimeter is complemented with an outer calorimeter to ensure high energy shower containment in the calorimeter. Fabrication, testing and calibration of the outer hadron calorimeter are carried out keeping in mind its importance in the energy measurement of jets in view of linearity and resolution. It will provide a net improvement in missing \et measurements at LHC energies. The outer hadron calorimeter will also be used for the muon trigger in coincidence with other muon chambers in CMS

Carte des températures politiques de la Russie

The result of elections to the Russian parliament show that towns are more concerned with democracy than the country still under the authority of some local communist party leaders ; that in the European part of Russia the North is more democratic than the South ; and that the autonomous regions are slowly opening to democratization perhaps out of fear of nationalist Russia.Les résultats des élections au Parlement de Russie montrent que les villes sont plus démocrates que les campagnes encore soumises à l’autorité des dirigeants locaux du parti communiste ; qu’en Russie d’Europe le nord est plus démocrate que le sud ; et que les régions «autonomes » restent peu ouvertes à la démocratisation, peut-être par crainte d’une Russie trop nationaliste.Los resultados de las elecciones para el parlamento de Rusia demuestran que las ciudades son más demócratas que el campo todavía sometido a la autoridad de los dirigentes locales del partido comunista ; que en la Rusia de Europa el norte es más demócrata que el sur ; y que las regiones «autónomas » son bastante reacias a la democratización, acaso por temor a una Rusia demasiado nacionalista.Kolossov Vladimir.
