Long-term outcomes of ecological restoration and management in urban forest patches
No full textUrbanization transforms ecological systems, altering soils, hydrology, climate, species pools, and landscape patterns. Municipalities are turning to ecological restoration of urban forests to provide essential ecosystem services. This dissertation examines long-term effects of ecological restoration of forest patches invaded by woody invasive plants within urban park natural areas in New York City, New York, USA. I compared invaded sites where restoration was initiated 15-20 years prior with similarly invaded urban park forests that had not been restored. Significantly lower invasive species abundance, more complex vertical forest structure, and greater native tree recruitment indicated that invasive species removal followed by planting resulted in divergent successional trajectories and achievement of the central goals of the restoration. However, regenerating species indicated novel future assemblages, and restored sites varied in degree of reinvasion. To examine sources of this variability and test the importance of management effort to success of ecological restoration in urban forest remnants, I compared plant communities, management records, indicators of disturbance, and site characteristics among and between restored and unrestored invaded patches and a less-disturbed urban forest remnant. Differences among restored plant communities were associated with total restoration effort and with soil surfaces impacted by urban conditions, indicating the importance of urban context and ongoing management effort to outcomes of ecological restoration in urban areas. To examine these soil effects and to test whether impacts of urbanization on soils affect long-term outcomes of ecological restoration in urban forest patches, I compared plant community composition of restored, unrestored and less-disturbed sites with soil physical and chemical characteristics and urban soil classification maps. No single soil impact dominated effects on plant community composition, but all sites were impacted by anthropogenic factors known to reduce plant growth, change distributions of soil biota, and alter nutrient cycles. I present an urban perspective on the use of succession theory in ecological restoration and introduce adaptive successional phasing as a tool, emphasizing site-specificity, long-term processes, and the importance of the urban environment’s effects on soils, species pools and disturbance regimes, and suggest that native species persisting and thriving in cities should be used in urban ecological restoration.Ph.

(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
(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.

Nuclear modification of light flavour and strangeness at LHC energies with ALICE
Full text linkThanks 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
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
