The new repetitive tendencies. A contextual analysis of the 2012 local elections
Dan Pavel
Sfera Politicii , 2012,
Abstract: The author considers that 2012 local elections in Romania marked the beginnings of a new party system and political system. 2012 was the year of popular movements and street protests, asking for political change. For the first time in post-communism, the coalition in power was defeated in Parliament with a censorship motion, followed by a new government, made from the previous opposition parties. In 2008, the party system moved towards tripartidism, but now the anti-system party is back, with a strong populist appeal. Romania passed already he two-turnover test” (in 1996 and 2000), in 2004 it was already the third turnover, but the big question remains: if the 2012 will mark the fourth turnover, why democracy is not yet consolidated?
The Party of Traitors”. Research on the Institutional Malformations and Systemic Self-Regulations of Post-Communist Democracy
Dan Pavel
Sfera Politicii , 2012,
Abstract: This research is based on the hypothesis that in Romania the consolidation of democracy was undermined not only at the beginning (path-dependency theory), but also at its end, in the last years. The political system seemed self-regulated, after the transition from extreme to moderate pluralism, and several turnovers, but the brutal intrusion of personalization and partisanship resulted in the fabrication of a parliamentarian pseudo-majority. With the help of a party which never participated in elections, by using blackmail, corruption and other dubious means, President B sescu and his party ruled over Romania. The author is trying to demonstrate the self-regulatory character of democracy, by showing how a legitimate majority came to power.
Anti-discrimination Philosophy and the Decline of Post-capitalist Democracies
Dan Pavel
Sfera Politicii , 2012,
Abstract: The author is trying to explain the contrasts existing between the expanding universe of anti-discrimination sanctions and the decline in legitimacy of democracy. The declining legitimacy affects both consolidated democracies, and newborn democracies. Inequality in the USA, but also at global level is illustrated with relevant statistics. The convergence between the crisis of democracy and the financial and economic global crisis is a major social and political threat. At the global level, after the Arab Spring, the third wave of democratization continued, while the quality of democracy substantially diminished. In the newborn Islamic democracies, discrimination against women, Christians, Jews, gay & lesbians, etc. continued, leading to arson, torture and killings.
Two Decades of Revolution. An Anti-Revisionist Essay
Dan Pavel
Sfera Politicii , 2013,
Abstract: The author examines the crucial differences between the breakdown of the totalitarian communist regimes in Central Europe and in Romania. For Central-Europeans, Westerners and the international community, the anti-communist revolutions of 1989 are related with 11/9, the Fall of the Berlin Wall”, and the Velvet Revolution”, while for Romanians, the same events are related with the bloody violent repression and confrontation, the faked show trial” of Ceau escu and his execution. While regime change in other former communist countries is related with terms and sintagms like transplacement, ruptforma, extrication or reforma pactada-ruptura pactada, pacted transition, the four-player game theory model”, none of them is relevant for the Romanian case. He is trying to find answers for the questions Why?” and How?” related with so many events before, during and after 1989.
Assessment of the usefulness of a diagnostic test: A survey of patient preference for diagnostic techniques in the evaluation of intestinal inflammation
Richard L Nelson, Alan Schwartz, Dan Pavel
BMC Medical Research Methodology , 2001, DOI: 10.1186/1471-2288-1-5
Abstract: Significant differences were seen in overall preference for white cell scan over barium enema and colonoscopy (p < 0.01) in both survey groups. Perceived discomfort and embarrassment demonstrated similar rankings.This patient preference combined with the reported accuracy of white cell scanning further establishes the usefulness of this means of IBD diagnosis.The radio labeled white cell scan has been shown to be an accurate means of detecting intestinal inflammation [1]. Our initial report of the use of Indium111 radiolabeled white cell scanning in the diagnosis of inflammatory bowel disease described a sensitivity and specificity of 97% and 100% respectively in 49 scans in 39 patients in all of whom confirmatory studies were done. Since that time, 1130 scans have been performed at our institution. Clinical follow-up of these patients has revealed only three cases of confirmed false negative scans. No cases of false positive scans have been encountered. This accuracy, it should be stressed, is not in the grading of disease activity, but in the dichotomous determination of disease presence and its anatomic location. The lack of confirmatory testing of all subsequent patients certainly results in the overestimation of accuracy [2], but not greatly so, since all patients have been available for clinical follow-up and diagnostic errors would become apparent with the passage of time. Even if it is a ten fold overestimate, the white cell scan still compares well with other diagnostic modalities. In 1993 Indium111 became unavailable in Chicago and we switched to the use of Technetium99. We found that the higher radiation dose of Technetium injected (20 mCI versus 0.5 mCI Indium) resulted in clearer images with less motion artifact, yet its shorter half life resulted in the total radiation dose to the patient being similar to Indium111. First images are available within 5 hours from the patient's arrival using Technetium, compared with 30 hours for Indium, making this appl
A Lack of Resolved Near-Infrared Polarization Across the Face of M51
Michael D. Pavel,Dan P. Clemens
Physics , 2012, DOI: 10.1088/2041-8205/761/2/L28
Abstract: The galaxy M51 was observed using the Mimir instrument on the Perkins telescope to constrain the resolved H-band (1.6 $\mu$m) polarization across the galaxy. These observations place an upper limit of $P_H<0.05%$ on the $H$-band polarization across the face of M51, at 0.6 arcsecond pixel sampling. Even with smoothing to coarser angular resolutions, to reduce polarization uncertainty, the $H$-band polarization remains undetected. The polarization upper limit at $H$-band, when combined with previous resolved optical polarimetry, rules out a Serkowski-like polarization dependence on wavelength. Other polarization mechanisms cannot account for the observed polarization ratio ($P_H/P{VRI} \lesssim 0.05$) across the face of M51.
HII Region Driven Galactic Bubbles and Their Relationship to the Galactic Magnetic Field
Michael D. Pavel,Dan P. Clemens
Physics , 2012, DOI: 10.1088/0004-637X/760/2/150
Abstract: The relative alignments of mid-infrared traced Galactic bubbles are compared to the orientation of the mean Galactic magnetic field in the disk. The orientations of bubbles in the northern Galactic plane were measured and are consistent with random orientations - no preferential alignment with respect to the Galactic disk was found. A subsample of HII region driven Galactic bubbles was identified, and as a single population they show random orientations. When this subsample was further divided into subthermal and suprathermal HII regions, based on hydrogren radio recombination linewidths, the subthermal HII regions showed a marginal deviation from random orientations, but the suprathermal HII regions showed significant alignment with the Galactic plane. The mean orientation of the Galactic disk magnetic field was characterized using new near-infrared starlight polarimetry and the suprathermal HII regions were found to preferentially align with the disk magnetic field. If suprathermal linewidths are associated with younger HII regions, then the evolution of young HII regions is significantly affected by the Galactic magnetic field. As HII regions age, they cease to be strongly linked to the Galactic magnetic field, as surrounding density variations come to dominate their morphological evolution. From the new observations, the ratios of magnetic-to-ram pressures in the expanding ionization fronts were estimated for younger HII regions.
UNDERGROUND ECONOMY'S MEASUREMENT METHODS
Dan Tudor LAZ?R,Bogdan Andrei MOLDOVAN,Alexandru PAVEL
Transylvanian Review of Administrative Sciences , 2008,
Abstract: It is argued that the underground economy is as old as government itself. Many people know how the underground economy functions, but a few are those who know its level. This article analyzes the most important measurement methods of the underground economy, as well as the way these methods could be applied. The methods are grouped into three categories: direct methods (that are using micro-economy data, gathered through sociological investigations, fiscal audits and other direct investigation methods), indirect methods (that use macroeconomic indicators in order to highlight the evolution and the level of the informal economy) and causative methods. The paper also describes five indirect indicators which are used for the underground economy estimation, and presents the advantages as well as the limits of the methods.
Study of Vivaldi Algorithm in Energy Constraint Networks
Patrik Moravek,Dan Komosny,Pavel Vajsar,Jaroslav Sveda
Advances in Electrical and Electronic Engineering , 2011,
Abstract: The presented paper discusses a viability of Vivaldi localization algorithm and synthetic coordinate system in general to be used for localization purposes in energy constraint networks. Synthetic coordinate systems achieve good results in IP based networks and thus, it could be a perspective way of node localization in other types of networks. However, transfer of Vivaldi algorithm into a different kind of network is a difficult task because the different basic characteristic of the network and network nodes. In this paper we focus on the different aspects of IP based networks and networks of wireless sensors which suffer from strict energy limitation. During our work we proposed a modified version of two dimensional Vivaldi localization algorithm with height system and developed a simulator tool for initial investigation of its function in ad-hoc energy constraint networks.
Testing Galactic Magnetic Field Models using Near-Infrared Polarimetry
Michael D. Pavel,Dan P. Clemens,April F. Pinnick
Physics , 2012, DOI: 10.1088/0004-637X/749/1/71
Abstract: This work combines new observations of NIR starlight linear polarimetry with previously simulated observations in order to constrain dynamo models of the Galactic magnetic field. Polarimetric observations were obtained with the Mimir instrument on the Perkins Telescope in Flagstaff, AZ, along a line of constant Galactic longitude (\ell = 150\circ) with 17 pointings of the 10' \times 10' field of view between -75\circ < b < 10\circ, with more frequent pointings towards the Galactic midplane. A total of 10,962 stars were photometrically measured and 1,116 had usable polarizations. The observed distribution of polarization position angles with Galactic latitude and the cumulative distribution function of the measured polarizations are compared to predicted values. While the predictions lack the effects of turbulence and are therefore idealized, this comparison allows significant rejection of A0-type magnetic field models. S0 and disk-even halo-odd magnetic field geometries are also rejected by the observations, but at lower significance. New predictions of spiral-type, axisymmetric magnetic fields, when combined with these new NIR observations, constrain the Galactic magnetic field spiral pitch angle to -6\circ \pm 2\circ.
