(Anti-)deuteron production and anisotropic flow measured with ALICE at the LHC
No full textThe high abundance of (anti-)deuterons in the statistics gathered in Run 1 of the LHC and the excellent performance of the ALICE setup allow for the simultaneous measurement of the elliptic flow and the deuteron production rates with a large transverse momentum () reach. The (anti-) deuterons are identified using the specific energy loss in the time projection chamber and the velocity information in the time-of-flight detector. The elliptic flow of (anti-)deuterons can provide insight into the production mechanisms of particles in heavy-ion collisions. Quark coalescence is one of the approaches to describe the elliptic flow of hadrons, while the production of light nuclei can be also depicted as a coalescence of nucleons. In these proceedings, the measured of deuterons produced in Pb--Pb collisions at =2.76TeV will be compared to expectations from coalescence and hydrodynamic models.The high abundance of (anti-)deuterons in the statistics gathered in Run 1 of the LHC and the excellent performance of the ALICE setup allow for the simultaneous measurement of the elliptic flow and the deuteron production rates with a large transverse momentum ( p T ) reach.

(Multi-)strange hadron and light (anti-)nuclei production with ALICE at the LHC
No full textThanks to its excellent tracking performance and particle identification capabilities, the ALICE detector allows for the identification of light (anti-)(hyper)nuclei and for the measurement of (multi-)strange particles over a wide range of transverse momentum. Deuterons, 3He and 4He and their corresponding anti-nuclei are identified via their specific energy loss in the Time Projection Chamber and the velocity measurement provided by the Time-Of-Flightdetector. Strange and multi-strange baryons and mesons as well as (anti-)hypertritons are reconstructed via their topological decays.Detailed measurements of (multi-)strange hadron production in pp, p–Pb and Pb–Pb collision and of light (anti-)nuclei and (anti-)hypertritons in Pb–Pb collisions with ALICE at the LHC are presented.The experimental results will be compared with the predictions of both statistical hadronization and coalescence models
Nuclear modification of light flavour and strangeness at LHC energies with ALICE
No full textThanks to its unique particle identification capabilities the ALICE detector is able to identify light-flavour, strange and multi-strange hadrons, including π, K, p, , Λ, Ξ and Ω, over a wide range of transverse momentum, from pp and p–Pb interactions up to central Pb–Pb collisions. The latest results on the nuclear modification factor, R (AA), as a function of the Pb–Pb collision centrality, is shown for various particle specie at centre-of-mass energy. For each particle specie, the R (AA) is compared with the nuclear modification factors R (pA) in p-Pb collisions to asses the presence of hot nuclear matter effects affecting the high-p (Τ) particle production in Pb–Pb collisions. The results on the R (AA) of charged hadrons at , the highest energy ever reached in the laboratory for heavy-ion collisions, is also shown
Riflessioni linguistiche sul tedesco e sul russo in Julya Rabinowich: un confronto tra narrazione autobiografica orale e il romanzo Spaltkopf
No full textLinguistic Reflections in German and Russian in Julya Rabinowich: A Comparative
Study of Oral Autobiographical Narrative and the Novel Spaltkopf.
The Austrian author Julya Rabinowich, born in Leningrad in 1970 to a family of Rus-
sian Jews and emigrated to Vienna at the age of 7, is one of the most renowned repre-
sentatives of contemporary literature in the German language. Rabinowich made her
literary debut in 2008 with Spaltkopf (Split Head), her most strongly autobiographical
novel. In 2012, the writer was interviewed by Michaela Bürger-Koftis as part of the
research project Polyphonie. Mehrsprachigkeit_Kreativität_Schreiben. This interview
can be understood as a linguistic biography, as Rabinowich recounts her experiences
related to the languages in her linguistic repertoire, focusing particularly on German
and Russian. From this account, the author’s Spracheinstellungen (linguistic attitudes),
as well as the impressions and emotions related to her two main languages, emerge.
The aim of this study is to compare the interview passages in which Rabinowich
expresses herself regarding German and Russian with excerpts from Spaltkopf where
the relationship of the protagonist, Mischka, with these two languages emerges. In this
162 Michaela Bürger-Koftis, Ramona Pellegrino
way, it will be possible to determine whether Spaltkopf reflects not only the author’s
migratory experience but also her linguistic biography. Furthermore, it will be analyz-
ed if and to what extent the expression of linguistic attitudes and emotions related to
German and Russian differs between the novel and the oral autobiographical account.
To examine how Rabinowich expresses her linguistic experiences and emotions relat-
ed to German and Russian, a qualitative analysis of the texts will be conducted, with
a theoretical approach based on the concepts of linguistic biography and verbalization
of emotions developed by Brigitta Busch and Reinhard Fiehler
Ramona Bennett, Tacoma, October 1976
No full textRamona Bennett (b. 1938) is a prominent Puyallap Tribe leader and activist. She was elected to the Puyallup Tribal Council in 1968, and served as Tribal Chairwoman from 1971 to 1978. Bennett is also a pioneer of fishing rights advocacy, co-founding the Survival of American Indians Association in 1964, and helping to bring “fish-in” protests to national prominence.
Much of Bennett’s work focuses on social welfare issues, mainly fighting for the rights of women, children and families. She began her social service work in the 1950s, with the Seattle’s American Indian Women’s Service League. In 1972, she co-founded the Local Indian Child Welfare Act Committee, where she developed a model for childhood and family services that she used to co-author and secure the national Indian Child Welfare Act of 1978, a Federal law that governs the removal and out-of-home placement of indigenous children. In the 1980s, she co-founded the Rainbow Youth and Family Services in Tacoma, a non-profit which she ran for many years.

Portrait of Helen Fiske Hunt Jackson, author of Ramona, [s.d.]
No full textPhotographic portrait of Helen Fiske Hunt Jackson, author of "Ramona", [s.d.]. Mrs. Jackson is pictured standing, wearing an elaborate dress with a huge bustle, made of what appears to be silk or satin. Her hands are folded across her waist while she looks to the right. She appears to be in her middle-age and wears the large locks of her curly hair pulled back from her face. She can be seen smiling, while a chair supports her dress to the right. Picture file card reads: "An American novelist, poet, and general writer, born at Amherst, mass. October 18, 1831; died at San Francisco, CA, August 12, 1885. She was the daughter of Professor Fiske, of Amherst. He first husband, Capt. E.B. Hunt, died in 1863. In 1870, she published a volume entitled "Verses". Her first prose volume, "Bits of Travel" (1872), was followed by "Bits of Talk About Home Matters" (1873), and "Bits of Travel at Home" (1878). In 1875 she married Mr. W.S. Jackson, of Colorado Springs. Here, she published "A Century of Dishonor", relating to the dealings of the U.S. Government with the Indians. This led to her appointment in 1883 as a special commissioner to examine into the condition and needs of the Mission Indians. After visiting the different tribes, she wrote "Ramona"(1884), a novel relating to the Mission Indians. Mrs. Jackson had previously written two novels in the "no Name" seires: "Mercy Philbric's Chioce" ["Choice"?] (1876) and "Hetty's Strange History"(1877). Besides these works, she published "The Story of Boon", a poem (1879), the training of children(1882), and several books for young people: "Nellie's Silver Mine" (1878), "Mammy Tittleback and her Family" (1881), and "The Hunter Cats of Connorloa" (1884). Since her death have appeared "Glimpses of Three Coasts", "Sonnets and Lyrics", "Zeph", a novel (1886), and "Between Whiles" (1887)"

Energy dependence and fluctuations of anisotropic flow in Pb-Pb collisions at √sNN = 5.02 and 2.76 TeV
No full textMeasurements of anisotropic flow coefficients with two- and multi-particle cu-
mulants for inclusive charged particles in Pb–Pb collisions at √sNN = 5.02 and 2.76 TeV
are reported in the pseudorapidity range |η| < 0.8 and transverse momentum 0.2 < pT <
50 GeV/c. The full data sample collected by the ALICE detector in 2015 (2010), corre-
sponding to an integrated luminosity of 12.7 (2.0) μb−1 in the centrality range 0–80%,
is analysed. Flow coefficients up to the sixth flow harmonic (v6) are reported and a de-
tailed comparison among results at the two energies is carried out. The pT dependence
of anisotropic flow coefficients and its evolution with respect to centrality and harmonic
number n are investigated. An approximate power-law scaling of the form vn(pT) ∼ pn/3 T
is observed for all flow harmonics at low pT (0.2 < pT < 3 GeV/c). At the same time, the ratios v /vn/m are observed to be essentially independent of p for most centralities up to
nmT
about pT = 10 GeV/c. Analysing the differences among higher-order cumulants of elliptic flow (v2), which have different sensitivities to flow fluctuations, a measurement of the stan- dardised skewness of the event-by-event v2 distribution P(v2) is reported and constraints on its higher moments are provided. The Elliptic Power distribution is used to parametrise P(v2), extracting its parameters from fits to cumulants. The measurements are compared to different model predictions in order to discriminate among initial-state models and to constrain the temperature dependence of the shear viscosity to entropy-density ratio
Constraints on jet quenching in p–Pb collisions at √sNN = 5.02 TeV measured by the event-activity dependence of semi-inclusive hadron-jet distributions
No full textThe ALICE Collaboration reports the measurement of semi-inclusive distributions of charged-particle jets recoiling from a high-transverse momentum trigger hadron in p–Pb collisions at √sNN = 5.02 TeV. Jets are reconstructed from charged-particle tracks using the anti-kT algorithm with resolution parameter R = 0.2 and 0.4. A data-driven statistical approach is used to correct the uncorrelated background jet yield. Recoil jet distributions are reported for jet transverse momentum 15 < pch < 50 GeV/c and are compared in T,jet various intervals of p–Pb event activity, based on charged-particle multiplicity and zero-degree neutral energy in the forward (Pb-going) direction. The semi-inclusive observable is self-normalized and such comparisons do not require the interpretation of p–Pb event activity in terms of collision geometry, in contrast to inclusive jet observables. These measurements provide new constraints on the magnitude of jet quenching in small systems at the LHC. In p–Pb collisions with high event activity, the average
medium-induced out-of-cone energy transport for jets with R = 0.4 and 15 < pch < 50 GeV/c is T,jet measured to be less than 0.4 GeV/c at 90% confidence, which is over an order of magnitude smaller than a similar measurement for central Pb–Pb collisions at √sNN =2.76TeV. Comparison is made to theoretical calculations of jet quenching in small systems, and to inclusive jet measurements in p–Pb collisions selected by event activity at the LHC and in d–Au collisions at RHIC
