Negli ultimi anni, in Italia sono stati tradotti un gran numero di opere letterarie cinesi grazie all’impegno e alla passione di numerosi sinologi, studiosi e traduttori italiani. Tuttavia, gli studi sulla traduzione della letteratura cinese sono, sia in Cina che in Italia, relativamente pochi e non sempre uniformi: in Cina è difficile trovare dati completi, sistematici e dotati di un certo valore di riferimento, e in Italia, una ricerca di questo tipo ha avuto origine nell’ambito degli studi sinologici italiani, piuttosto che in quello degli studi sulla traduzione. A partire da una rassegna dei principali approcci agli studi sulla traduzione (letteraria) dalla seconda metà del XX secolo fino ai nostri giorni, questo lavoro di tesi tenta di analizzare da un lato le tendenze generali relative alla traduzione e alla pubblicazione delle opere letterarie cinesi in Italia in un arco temporale che va dal 1942 al 2018, tramite alcune analisi di tipo sia quantitativo che qualitativo basate su una tabella di dati concernenti la letteratura cinese sul mercato editoriale italiano che è stata costruita appositamente; dall’altro, questa ricerca intende investigare le strategie utilizzate per tradurre i diversi riferimenti culturali riscontrati nel corpus di testi scelti e che sono stati suddivisi nelle seguenti categorie: antroponimi, intertestualità, riferimenti al contesto politico e culturale, gastronomia e altri riferimenti culturali. Attraverso un’analisi comparativa e descrittiva dei testi di partenza e dei testi di arrivo, ai fini della tesi si sono indagate le problematiche riguardanti la traduzione e la ricezione della letteratura cinese in Italia e le tendenze che tale letteratura ha avuto sia in ambito editoriale che nel campo della traduzione letteraria.

Rapidity-odd directed flow (v1) measurements for charged pions, protons, and antiprotons near midrapidity (y=0) are reported in sNN=7.7, 11.5, 19.6, 27, 39, 62.4, and 200 GeV Au+Au collisions as recorded by the STAR detector at the Relativistic Heavy Ion Collider. At intermediate impact parameters, the proton and net-proton slope parameter dv1/dy|y=0 shows a minimum between 11.5 and 19.6 GeV. In addition, the net-proton dv1/dy|y=0 changes sign twice between 7.7 and 39 GeV. The proton and net-proton results qualitatively resemble predictions of a hydrodynamic model with a first-order phase transition from hadronic matter to deconfined matter, and differ from hadronic transport calculations.

We report the STAR measurements of dielectron (e(+)e(-)) production at midrapidity (|y(ee)|<1) in Au+Au collisions at √[s(NN)]=200  GeV. The measurements are evaluated in different invariant mass regions with a focus on 0.30-0.76 (ρ-like), 0.76-0.80 (ω-like), and 0.98-1.05 (ϕ-like)   GeV/c(2). The spectrum in the ω-like and ϕ-like regions can be well described by the hadronic cocktail simulation. In the ρ-like region, however, the vacuum ρ spectral function cannot describe the shape of the dielectron excess. In this range, an enhancement of 1.77±0.11(stat)±0.24(syst)±0.33(cocktail) is determined with respect to the hadronic cocktail simulation that excludes the ρ meson. The excess yield in the ρ-like region increases with the number of collision participants faster than the ω and ϕ yields. Theoretical models with broadened ρ contributions through interactions with constituents in the hot QCD medium provide a consistent description of the dilepton mass spectra for the measurement presented here and the earlier data at the Super Proton Synchrotron energies.

Local parity-odd domains are theorized to form inside a quark-gluon plasma which has been produced in high-energy heavy-ion collisions. The local parity-odd domains manifest themselves as charge separation along the magnetic field axis via the chiral magnetic effect. The experimental observation of charge separation has previously been reported for heavy-ion collisions at the top RHIC energies. In this Letter, we present the results of the beam-energy dependence of the charge correlations in Au+Au collisions at midrapidity for center-of-mass energies of 7.7, 11.5, 19.6, 27, 39, and 62.4 GeV from the STAR experiment. After background subtraction, the signal gradually reduces with decreased beam energy and tends to vanish by 7.7 GeV. This implies the dominance of hadronic interactions over partonic ones at lower collision energies.

We report measurements of single- and double-spin asymmetries for W^{±} and Z/γ^{*} boson production in longitudinally polarized p+p collisions at sqrt[s]=510  GeV by the STAR experiment at RHIC. The asymmetries for W^{±} were measured as a function of the decay lepton pseudorapidity, which provides a theoretically clean probe of the proton's polarized quark distributions at the scale of the W mass. The results are compared to theoretical predictions, constrained by polarized deep inelastic scattering measurements, and show a preference for a sizable, positive up antiquark polarization in the range 0.05

We report the first measurements of the moments--mean (M), variance (σ(2)), skewness (S), and kurtosis (κ)--of the net-charge multiplicity distributions at midrapidity in Au+Au collisions at seven energies, ranging from sqrt[sNN]=7.7 to 200 GeV, as a part of the Beam Energy Scan program at RHIC. The moments are related to the thermodynamic susceptibilities of net charge, and are sensitive to the location of the QCD critical point. We compare the products of the moments, σ(2)/M, Sσ, and κσ(2), with the expectations from Poisson and negative binomial distributions (NBDs). The Sσ values deviate from the Poisson baseline and are close to the NBD baseline, while the κσ(2) values tend to lie between the two. Within the present uncertainties, our data do not show nonmonotonic behavior as a function of collision energy. These measurements provide a valuable tool to extract the freeze-out parameters in heavy-ion collisions by comparing with theoretical models.
