Long-term stability of short-term intensive languageâaction therapy in chronic aphasia: A 1â2 year follow-up study
Background. Intensive aphasia therapy can improve language functions in chronic aphasia over a short therapy interval of 2-4 weeks. For one intensive method, intensive language-action therapy, beneficial effects are well documented by a range of randomized controlled trials. However, it is unclear to date whether therapy-related improvements are maintained over years. Objective. The current study aimed at investigating long-term stability of ILAT treatment effects over circa 1-2 years (8-30 months). Methods. 38 patients with chronic aphasia participated in ILAT and were re-assessed at a follow-up assessment 8-30 months after treatment, which had been delivered 6-12.5 hours per week for 2-4 weeks. Results. A standardized clinical aphasia battery, the Aachen Aphasia Test, revealed significant improvements with ILAT that were maintained for up to 2.5 years. Improvements were relatively better preserved in comparatively young patients (<60 years). Measures of communicative efficacy confirmed improvements during intensive therapy but showed inconsistent long-term stability effects. Conclusions. The present data indicate that gains resulting from intensive speech-language therapy with ILAT are maintained up to 2.5 years after the end of treatment. We discuss this novel finding in light of a possible move from sparse to intensive therapy regimes in clinical practice
Between existential mobility and intimacy 5.0:translocal care in pandemic times
The COVID-19 pandemic has reconfigured every social, political, economic and cultural aspect of modern society. Millions of people have been stuck in lockdown within and across borders, national and regional terrains, in their homes and worse places. At this time of unprecedented change and âstuckednessâ, digital communication technologies have served as a lifeline to forge and nurture communication, intimate ties and a sense of continuity and belongingness. But being stuck and simultaneously virtually mobile has brought many difficulties, tensions and paradoxes. In this paper we discuss first insights from a study with 15 members of the older Culturally and Linguistically Diverse (CALD) population in Victoria, Australia to explore experiences of being physically stuck and virtually mobile. We find practices of translocal care â ways of caring for distant others through digital technologies, has been made more complex by the pandemic and shaped by two dynamics: networked collective âexistential mobilityâ, and a quantification of feeling that we call âintimacy 5.0â
Production of -mesons in pp and pn reactions
We investigate the cross section for the reaction near
threshold and at medium energies. An effective Lagrangian approach with
one-pion exchange is applied to analyze different contributions to the cross
section for different isospin channels. The Reggeon exchange mechanism is also
considered. The results are used to calculate the contribution of the
meson to the cross sections and invariant mass distributions of the
reactions and . It is found that the
experimental observation of mesons in the reaction is much more promising than the observation of mesons in the
reaction .Comment: 26 pages, including 11 eps figures, to be bublished in J. Phys.
Financialisation in the green economy: material connections, markets-in-the-making and Foucauldian organising actions
This paper explores the connections between financialisation in the green economy and the material commodification processes that underpin this economy. It argues that these connections are important and can be usefully conceived in terms of spaces of mutuality. These spaces of mutuality direct attention to the material processes of value creation at the level of real environmental assets. That these material processes appear thin, sluggish, fractured, hybridised or stalled in practice invites new modes of analytical engagement. One important mode of analysing these emergent green projects is to emphasise their status as durable processes of becoming or what could be called markets-in-the-making, by going beyond forms of market and economic reductionism. Michel Foucault's analysis of neoliberalism and his idea of âorganising actionsâ prove useful in this regard. Foucauldian organising actions render markets-in-the-making projects visible as durable governmental apparatuses made of disparate elements that are geographically specific, historically contingent and are aligned with an overarching market telos. Drawing on an empirical case of Reducing Emissions from Deforestation and Forest Degradation plus carbon stock enhancement and sustainable forest management (REDD+) in Nigeriaâs Cross River, the paper analyses organising actions along four meta-processes â problematisations, visions, implementation and stabilisation. It concludes by highlighting the wider implications for work on environmental financialisation
Phenomenological analysis of K+ meson production in proton-nucleus collisions
Total and differential cross sections from literature, on the production of
K+ mesons in pA interactions at projectile energies between T=0.8 and 2.9 GeV,
covering the transition across the free nucleon-nucleon threshold at 1.58 GeV,
have been investigated. From the target-mass dependence of the production cross
sections no evidence for the expected change of the dominant reaction mechanism
from two-step to direct kaon production was found. At T=1.0 GeV the A
dependences of the total cross sections and of the most recent data from
COSY-Juelich, differential cross sections measured under forward angles, are
strongly different. The invariant K+ production cross sections show an overall
exponential scaling behavior with the squared four-momentum transfer between
the beam proton and the produced K+ meson for t< -0.05 GeV^2 independent of the
beam energy and emission angle. The data from COSY-Juelich reveal a strongly
different t dependence in the region of t>0 GeV^2. Further data at forward
angles and different beam energies should be taken in order to explore this
region of kinematically extreme conditions.Comment: 9 Pages, 11 Figure
Shape Isomerism at N = 40: Discovery of a Proton Intruder in 67Co
The nuclear structure of 67Co has been investigated through 67Fe beta-decay.
The 67Fe isotopes were produced at the LISOL facility in proton-induced fission
of 238U and selected using resonant laser ionization combined with mass
separation. The application of a new correlation technique unambiguously
revealed a 496(33) ms isomeric state in 67Co at an unexpected low energy of 492
keV. A 67Co level scheme has been deduced. Proposed spin and parities suggest a
spherical (7/2-) 67Co ground state and a deformed first excited (1/2-) state at
492 keV, interpreted as a proton 1p-2h prolate intruder state.Comment: 4 pages, 5 figures, preprint submitted to Physical Review Letter
Conserving Conflict? Transfrontier Conservation, Development Discourses and Local Conflict Between South Africa and Lesotho
This paper describes and analyses how discourses of conservation and development as well as migrant labour practices can be understood as transnational dynamics that both cement and complicate transnational relations. It also looks into how these dynamics articulate with, shape and are being shaped by âthe localâ. Focusing on the north-eastern boundary of Lesotho in the area of the âMaloti-Drakensberg transfrontier conservation and development projectâ, we show how conflictual situations put the ethnographic spotlight on the ways in which âlocal peopleâ in Lesotho deal with dual forces of localisation and transnationalisation. We argue that they accommodate, even appropriate, these dual pressures by adopting an increasingly flexible stance in terms of identity, alliances, livelihood options and discourses
Subthreshold antiproton production in proton-carbon reactions
Data from KEK on subthreshold antiproton as well as on pi(+-) and K(+-)
production in proton-nucleus reactions are described at projectile energies
between 3.5 and 12.0 GeV. We use a model which considers a hadron-nucleus
reaction as an incoherent sum over collisions of the projectile with a varying
number of target nucleons. It samples complete events and allows thus for the
simultaneous consideration of all particle species measured. The overall
reproduction of the data is quite satisfactory. It is shown that the
contributions from the interaction of the projectile with groups of several
target nucleons are decisive for the description of subthreshold production.
Since the collective features of subthreshold production become especially
significant far below the threshold, the results are extrapolated down to COSY
energies. It is concluded that an antiproton measurement at ANKE-COSY should be
feasible, if the high background of other particles can be efficiently
suppressed.Comment: 15 pages, 5 figures, gzipped tar file, submitted to J. Phys. G v2:
