The management of cultural adjustment: Central-South-East European ethnic minorities in the USA
Mihaela ARSENE
Economia : Seria Management , 2010,
Abstract: The paper focuses on one particular instance in the management of change as accomplished/implemented in the USA by the ethnic minorities originally from Italy, Greece and Romania. The author presents a diachronic survey of the literature against the author’s own findings. The paper identifies common patterns in the cultural adjustment of all three ethnic groups surveyed and analyses them against the specific developmental pressures in each group. Historic, economic and sociological data contribute to outlining the distinct profile of each ethnic groups under investigation, as well as the assimilation patterns at work throughout its evolution in the new US cultural environment.

Abstract: At present, lichenized fungi are used in biomonitoring studies of air quality, being good receptors in the climate change. This paper aims to investigate surface micromorphology of Xanthoria parietina and Phaeophyscia orbicularis species (Lecanoromycetes, Ascomycota). The study also includes the investigation of selected chemical parameters as pH and conductivity of the lichenized fungi samples collected from various locations in the Ia i County (Romania). Measurements of the pH provide information on the degree of pollution in the location of interest. Bark trees pH was also investigated in order to see if our matrix substrate influences the pH of the interest lichenized fungi samples.

Abstract: Globalization process has determined a lot of changes at an individual level. These changes arereflected in the modern family profile, which creates individuals able to accomplish the goal ofglobalization. Thus, young people from the Romanian society, take as a goal, the opportunity ofliving the country, during or after they finish their studies, for studying or for working in Westerncountries. This paper tries to analyze the migration of population phenomenon, from economicunstable areas to economic economic stable areas, and, also, the impact of this phenomenon ontheir families.

Tourism in Romania, after 1990
Revista Roman? de Statistic? , 2010,
Abstract: With complex representative tourist areas, Romania has had a significant tourism potential (Fagaras Country, Barsa Country, Hateg Country, Dorna Country, Prahova Valley, Buzau Valley, Olt Valley, Teleajen, Valley, Jiu Valley ,Vrancea Country, boilers Danube, Transylvanian plateau, Mountains National Park, National Park Semenic National Park Retezat, Nera Gorge, Székely, edge Sibiu, Rucar Bran road, Danube Delta, Romanian Black Stone Land respectively) which, in my view, was not sufficient value.Highlighting the tourism potential of our country, creating, in fact, tourist attractiveness depends directly by basic technical and service quality without which no tourist assets, however valuable, can not be realized.Romanian tourism offer was and is, in this view, faced with numerous problems that we believe should be considered in greater development programs, developed throughout the country and regional level.Keywords: tourism potential, tourist offer, types of tourism, service quality, specific statistical indicators, value for money.
Centrality and rapidity dependence of particle ratios in Au+Au and Cu+Cu collisions at $\sqrt{s_{NN}}$ = 62.4 GeV
Ionut Arsene,for the BRAHMS Collaboration
Physics , 2009, DOI: 10.1088/0954-3899/36/6/064004
Abstract: We report on preliminary identified particle ratios from Au+Au collisions at $\sqrt{s_{NN}} = 62.4$ GeV in different centrality classes, measured with the BRAHMS spectrometer. Results from Cu+Cu and p+p collisions at mid-rapidity at the same energy are also included. The average transverse momenta of particle spectra, anti-particle to particle ratios and $K/\pi$ ratios dependence on centrality and rapidity are shown and discussed.
Production of Mesons and Baryons at High Rapidity and High Pt in Proton-Proton Collisions at sqrt(s) = 200 GeV
BRAHMS Collaboration,I. Arsene
Physics , 2007, DOI: 10.1103/PhysRevLett.98.252001
Abstract: We present particle spectra for charged hadrons $\pi^\pm, K^\pm, p$ and $\bar{p}$ from pp collisions at $\sqrt{s}=200$ GeV measured for the first time at forward rapidities (2.95 and 3.3). The kinematics of these measurements are skewed in a way that probes the small momentum fraction in one of the protons and large fractions in the other. Large proton to pion ratios are observed at values of transverse momentum that extend up to 4 GeV/c, where protons have momenta up to 35 GeV. Next-to-leading order perturbative QCD calculations describe the production of pions and kaons well at these rapidities, but fail to account for the large proton yields and small $\bar{p}/p$ ratios.
Single Transverse Spin Asymmetries of Identified Charged Hadrons in Polarized p+p Collisions at $\sqrt{s}$ = 62.4 GeV
BRAHMS Collaboration,I. Arsene
Physics , 2008, DOI: 10.1103/PhysRevLett.101.042001
Abstract: The first measurements of $x_F$-dependent single spin asymmetries of identified charged hadrons, $\pi^{\pm}$, $K^{\pm}$, and protons, from transversely polarized proton-proton collisions at 62.4 GeV at RHIC are presented. The measurements extend to high-$x_F$ ($|x_F|\sim 0.6$) in both the forward and backward directions.Large asymmetries are seen in the pion and kaon channels. The asymmetries in inclusive $\pi^{+}$ production, $A_N(\pi^+)$, increase with $x_F$ from 0 to $\sim$0.25 %at $x_F = 0.6$ and $A_N(\pi^{-})$ decrease from 0 to $\sim$$-$0.4. Even though $K^-$ contains no valence quarks, observed asymmetries for $K^-$ unexpectedly show positive values similar to those for $K^+$, increasing with $x_F$, whereas proton asymmetries are consistent with zero over the measured kinematic range. Comparisons of the data with predictions of QCD-based models are presented. The flavor dependent single spin asymmetry measurements of identified hadrons allow for stringent tests of theoretical models of partonic dynamics in the RHIC energy regime.
Rapidity dependent $K/π$ ratios in Au+Au collisions at $\sqrt{s_{NN}}$ = 62.4 GeV
I. C. Arsene
Physics , 2008, DOI: 10.1088/0954-3899/35/10/104056
Abstract: We report on measurements of identified particle yields from Au-Au collisions at $\sqrt{s_{NN}} = 62.4$ GeV made with the BRAHMS spectrometer. Here we will concentrate on the charged $K/\pi$ ratios as function of rapidity and baryo-chemical potential. We find that the $K/\pi$ ratios measured at different rapidities in the analysed dataset have a common dependence with the same ratios measured in mid-rapidity at SPS energies when plotted as function of the $\bar{p}/p$ ratio. The theoretical models used for comparison, UrQMD and AMPT, give a reasonable description of the particle yields at mid-rapidity but fail to do so for the $K/\pi$ ratios at forward rapidity.
Transverse Momentum Spectra in Au+Au and d+Au Collisions at $\sqrt{s_{NN}}$=200 GeV and the Pseudorapidity Dependence of High p$_T$ Suppression
The BRAHMS Collaboration,I. Arsene
Physics , 2003, DOI: 10.1103/PhysRevLett.91.072305
Abstract: We present spectra of charged hadrons from Au+Au and d+Au collisions at $\sqrt{s_{NN}}=200$ GeV measured with the BRAHMS experiment at RHIC. The spectra for different collision centralities are compared to spectra from ${\rm p}+\bar{{\rm p}}$ collisions at the same energy scaled by the number of binary collisions. The resulting ratios (nuclear modification factors) for central Au+Au collisions at $\eta=0$ and $\eta=2.2$ evidence a strong suppression in the high $p_{T}$ region ($>$2 GeV/c). In contrast, the d+Au nuclear modification factor (at $\eta=0$) exhibits an enhancement of the high $p_T$ yields. These measurements indicate a high energy loss of the high $p_T$ particles in the medium created in the central Au+Au collisions. The lack of suppression in d+Au collisions makes it unlikely that initial state effects can explain the suppression in the central Au+Au collisions.
