    Immigrant Workers, Human Capital Investment and the Shape of Immigration Reform

    President Obama\u27s speech in Las Vegas last month kicked off Congressional debates on immigration policy. While border security and illegal immigration are still high profile and thorny issues, slow economic growth following the Great Recession has helped to shift the focus to how the United States can change policy to better suit economic needs. Where do immigrants fit into the labor force, how can they fit better, and what is the likely shape of future policy changes

    The New Geography of Immigration and Local Policy Responses

    Full text link
    Recent years have seen a shift in the settlement patterns of U.S. immigrants, away from well-established metro areas and into new destinations, including suburban areas. Audrey Singer discusses major trends in immigration, variation in local policy responses, and the prospects for federal immigration reform

    Examines 2000-09 demographic and economic trends and highlights five new realities: growth and outward expansion, population diversification, aging, uneven higher educational attainment, and income polarization. Analyzes national and regional challenges

    A neurophenomenological approach to non-ordinary states of consciousness: hypnosis, meditation, and psychedelics

    Full text link
    No contemporary unifying framework has been provided for the study of non-ordinary states of consciousness (NSCs) despite increased interest in hypnosis, meditation, and psychedelics. NSCs induce shifts in experiential contents (what appears to the experiencer) and/or structure (how it appears). This can allow the investigation of the plastic and dynamic nature of experience from a multiscale perspective that includes mind, brain, body, and context. We propose a neurophenomenological (NP) approach to the study of NSCs which highlights their role as catalysts of transformation in clinical practice by refining our understanding of the relationships between experiential (subjective) and neural dynamics. We outline the ethical implications of the NP approach for standard conceptions of health and pathology as well as the crucial role of experience-based know-how in NSC-related research and application. Keywords: agency; altered states of consciousness; hypnosis; meditation; psychedelics; sel

    Nighttime Magnetic Perturbation Events Observed in Arctic Canada: 3. Occurrence and Amplitude as Functions of Magnetic Latitude, Local Time, and Magnetic Disturbance Indices

    Rapid changes of magnetic fields associated with nighttime magnetic perturbation events (MPEs) with amplitudes |ΔB| of hundreds of nT and 5–10 min duration can induce geomagnetically induced currents (GICs) that can harm technological systems. This study compares the occurrence and amplitude of nighttime MPEs with |dB/dt| ≥ 6 nT/s observed during 2015 and 2017 at five stations in Arctic Canada ranging from 64.7° to 75.2° in corrected geomagnetic latitude (MLAT) as functions of magnetic local time (MLT), the SME (SuperMAG version of AE) and SYM/H magnetic indices, and time delay after substorm onsets. Although most MPEs occurred within 30 min after a substorm onset, ∼10% of those observed at the four lower latitude stations occurred over two hours after the most recent onset. A broad distribution in local time appeared at all five stations between 1700 and 0100 MLT, and a narrower distribution appeared at the lower latitude stations between 0200 and 0700 MLT. There was little or no correlation between MPE amplitude and the SYM/H index; most MPEs at all stations occurred for SYM/H values between −40 and 0 nT. SME index values for MPEs observed \u3e1 h after the most recent substorm onset fell in the lower half of the range of SME values for events during substorms, and dipolarizations in synchronous orbit at GOES 13 during these events were weaker or more often nonexistent. These observations suggest that substorms are neither necessary nor sufficient to cause MPEs, and hence predictions of GICs cannot focus solely on substorms
