    The purpose of this research was to analyze generalization effects following semantic feature treatment (SFT) for aphasia. The effectiveness of SFT at improving accuracy and speed of word retrieval, generalization to untreated words and discourse tasks and the influence of shared features was examined. The three participants improved in retrieval accuracy of treated words. Accuracy of untreated words improved for two participants; retrieval accuracy for words with shared features improved slightly more than for words with no-shared features. Two participants showed variable generalization to discourse tasks and improved speed of accurate responses. Clinical implications and future research directions are discussed

    Welcoming the Stranger: African Refugees and Israel’s Asylum Regime

    Get PDF
    This paper will explore the Israeli asylum regime and its development since the state’s inception and will discuss the rationales and motives behind national policy and public perception of asylum seekers. Over the last decade, Israel’s asylum regime has been significantly upgraded to meet the growing needs of the state to manage an unprecedented flow of asylum seekers entering into the country. Upon arriving in Israel, however, asylum seekers have found a state that is reluctant to take them in and a citizenry unwelcoming to outsiders perceived as a divisive “other.” This “otherness” is perceived as a danger to many in Israeli society, who bear concerns that, as a fact of their “otherness,” asylum seekers threaten to alter the social and political dynamic of a state that is still young and working to ameliorate a number of national issues. The paper will analyze this perception and discuss how it has influenced the development of the asylum regime. The first section provides an overview of the international asylum regime in order to contextualize the history and events in Israel. The second section provides a history and analysis of the development of the Israeli asylum regime from its earliest days to the present, highlighting key factors and events that have impacted the growth of the regime. The third section discusses a number of influential facets of Israeli society that impact Israel’s approach to and perspective of refugees. The final section offers conclusions on how the Israeli asylum regime may move forward, extrapolates the case of Israel to a global context, and suggests possible paths for future research

    Treading Water: How Citizens, States, and the Environmental Protection Agency Can Restore Proper Criminal Enforcement of the Clean Water Act\u27s National Pollutant Discharge Elimination System

    Upon the passage of the Clean Water Act (“CWA”) in 1972, primary responsibility for protecting the United States\u27 water quality and preventing water pollution shifted from the states to the Environmental Protection Agency (“EPA”). The program at the heart of the Clean Water Act, the National Pollutant Discharge Elimination System (“NPDES”), requires anyone who discharges pollutants into the waters of the United States to abide by the terms of a permit issued under the program. If a discharge occurs in violation of the permit or without a permit, and prosecutors are able to prove the responsible party acted with ordinary negligence, criminal charges can be brought under the statute. Forty-seven states have been authorized by the EPA to run and enforce an NPDES permit program within their own borders. Instead of adopting an intent standard of ordinary negligence as the federal statute and regulations require, many states have been authorized to run their programs with “gross” or “criminal” negligence intent standards. Litigation over Idaho’s recent program approval could force the EPA to assume responsibility over all approved state programs that are out of compliance with the CWA and the EPA’s regulations. This outcome could overload the EPA and put the NPDES program in jeopardy of complete failure. But, with a few regulatory changes, the EPA can prevent further litigation, comply with its non-discretionary duties laid out in the CWA, and ensure the proper level of criminal deterrence needed to protect water quality

    A longitudinal analysis of DAO decentralization

    Get PDF
    Decentralized Autonomous Organizations (DAOs) offer a new method of governance that relies on a blockchain's transparent, decentralized, and programmable qualities (Tan et al. 2024). Previous research on DAOs found low participation rates in voting and a high level of inequality and centralization (Tan et al. 2024). A longitudinal analysis of DAO proposals was performed to determine if DAOs become progressively decentralized over time. The Gini and Nakamoto coefficients were calculated for 33 DAOs, and it was found that DAOs typically remained highly centralized and unequal and grew more centralized regardless of the type of decentralized application (dApp) the DAO governed

    Measurements of double-helicity asymmetries in inclusive J/ψJ/\psi production in longitudinally polarized p+pp+p collisions at s=510\sqrt{s}=510 GeV

    We report the double helicity asymmetry, ALLJ/ψA_{LL}^{J/\psi}, in inclusive J/ψJ/\psi production at forward rapidity as a function of transverse momentum pTp_T and rapidity y|y|. The data analyzed were taken during s=510\sqrt{s}=510 GeV longitudinally polarized pp++pp collisions at the Relativistic Heavy Ion Collider (RHIC) in the 2013 run using the PHENIX detector. At this collision energy, J/ψJ/\psi particles are predominantly produced through gluon-gluon scatterings, thus ALLJ/ψA_{LL}^{J/\psi} is sensitive to the gluon polarization inside the proton. We measured ALLJ/ψA_{LL}^{J/\psi} by detecting the decay daughter muon pairs μ+μ\mu^+ \mu^- within the PHENIX muon spectrometers in the rapidity range 1.2<y<2.21.2<|y|<2.2. In this kinematic range, we measured the ALLJ/ψA_{LL}^{J/\psi} to be 0.012±0.0100.012 \pm 0.010~(stat)~±\pm~0.0030.003(syst). The ALLJ/ψA_{LL}^{J/\psi} can be expressed to be proportional to the product of the gluon polarization distributions at two distinct ranges of Bjorken xx: one at moderate range x0.05x \approx 0.05 where recent RHIC data of jet and π0\pi^0 double helicity spin asymmetries have shown evidence for significant gluon polarization, and the other one covering the poorly known small-xx region x2×103x \approx 2\times 10^{-3}. Thus our new results could be used to further constrain the gluon polarization for x<0.05x< 0.05.Comment: 335 authors, 10 pages, 4 figures, 3 tables, 2013 data.

    Azimuthally anisotropic emission of low-momentum direct photons in Au++Au collisions at sNN=200\sqrt{s_{_{NN}}}=200 GeV

    Full text link
    The PHENIX experiment at the Relativistic Heavy Ion Collider has measured 2nd and 3rd order Fourier coefficients of the azimuthal distributions of direct photons emitted at midrapidity in Au++Au collisions at sNN=200\sqrt{s_{_{NN}}}=200 GeV for various collision centralities. Combining two different analysis techniques, results were obtained in the transverse momentum range of 0.4<pT<4.00.4<p_{T}<4.0 GeV/cc. At low pTp_T the second-order coefficients, v2v_2, are similar to the ones observed in hadrons. Third order coefficients, v3v_3, are nonzero and almost independent of centrality. These new results on v2v_2 and v3v_3, combined with previously published results on yields, are compared to model calculations that provide yields and asymmetries in the same framework. Those models are challenged to explain simultaneously the observed large yield and large azimuthal anisotropies.Comment: 552 authors, 15 pages, 9 figures, 3 tables, 2007 and 2010 data. v2 is version accepted for publication by Phys.

    ϕ\phi meson production in dd++Au collisions at sNN=200\sqrt{s_{_{NN}}}=200 GeV

    Full text link
    The PHENIX experiment has measured ϕ\phi meson production in dd++Au collisions at sNN=200\sqrt{s_{_{NN}}}=200 GeV using the dimuon and dielectron decay channels. The ϕ\phi meson is measured in the forward (backward) dd-going (Au-going) direction, 1.2<y<2.21.2<y<2.2 (2.2<y<1.2-2.2<y<-1.2) in the transverse-momentum (pTp_T) range from 1--7 GeV/cc, and at midrapidity y<0.35|y|<0.35 in the pTp_T range below 7 GeV/cc. The ϕ\phi meson invariant yields and nuclear-modification factors as a function of pTp_T, rapidity, and centrality are reported. An enhancement of ϕ\phi meson production is observed in the Au-going direction, while suppression is seen in the dd-going direction, and no modification is observed at midrapidity relative to the yield in pp++pp collisions scaled by the number of binary collisions. Similar behavior was previously observed for inclusive charged hadrons and open heavy flavor indicating similar cold-nuclear-matter effects.Comment: 484 authors, 16 pages, 12 figures, 6 tables. v1 is the version accepted for publication in Phys.
