    Electric Vehicles: Market Opportunities in China

    Electric vehicles (EVs) offer an exciting opportunity in China both in terms of the potential to build a domestic manufacturing base and the potential to create a strong domestic market for the product. The Chinese nation stands to benefit from both supply-side and demand-side promotion due to the economic stimulus from EV manufacturing and export, the environmental benefits of reduced air pollution and reduced greenhouse gas emissions, and the energy security benefits of transitioning away from foreign oil dependence. The Chinese have several advantages when it comes to stimulating EV industry development and EV deployment, including: leadership in battery technology, great potential for cost competitiveness, an enormous and emerging number of new car buyers, and high level government support. Yet a number of challenges must be taken into account as well, including: shortfalls in overall automobile R&D spending, consumer concerns about Chinese cars’ safety and reliability, enhancing the appeal of the Chinese brand, and heavy national infrastructure demands. This paper will seek to examine the opportunities and challenges associated with EV deployment in China and identify industry actions and policy measures to facilitate the process

    Punishment but Not a Penalty? Punitive Damages Are Impermissible Under Foreign Substantive Law

    Get PDF
    It is a well-established principle that no court applies the penal laws of another sovereign. But what exactly is a penal law? According to Judge Cardozo, a penal law effects “vindication of the public justice” rather than “reparation to one aggrieved.” Although courts have historically treated punitive damages as a purely civil remedy, that attitude has shifted over time. Modern American punitive damages serve not to compensate the plaintiff but to punish the defendant on behalf of the whole community. Therefore, when courts rely on foreign substantive law to impose punitive damages, they arguably violate the well-established principle that no court applies the penal laws of another sovereign. This Note argues that punitive damages are penal in the choice-of-law sense, and state courts violate the penal exception when they impose punitive damages under or alongside foreign substantive law. It proposes several possible means to resolve this dissonance and ultimately concludes that courts should altogether eliminate the prospect of punitive damages when they impose liability under foreign substantive law

    Counting Zeros: The Every Student Succeeds Act and the Testing Opt-Out Movement

    The story begins with threatening letters. In October 2014, the U.S. Department of Education reminded Colorado’s chief state school officer that the department “ha[d], in fact, withheld Title I, Part A administrative funds . . . from a number of States for failure to comply with the assessment requirements” under the Elementary and Secondary Education Act. Given the occasion, the department implied, it wouldn’t hesitate to be ruthless. Colorado could be forgiven for assuming it was authorized to craft its own policies in this arena; according to the Wall Street Journal, the Every Student Succeeds Act (ESSA) represented “the largest devolution of federal control to the states in a quarter-century.” But what precisely had become of No Child Left Behind’s 95 percent participation requirement? In this Essay, I parse the state and federal laws at play to determine whether the federal government really has the legal authority and political will to withhold funding from states that allow students to opt out of standardized assessments. I also evaluate Colorado’s proposed response to the federal threat, gauging its conformity with the letter and the spirit of ESSA

    Swift/UVOT Photometry of the Planetary Nebula WeBo 1: Unmasking A Faint Hot Companion Star

    We present an analysis of over 150 ks of data on the planetary nebula WeBo 1 (PN G135.6+01.0) obtained with the Swift Ultraviolet Optical Telescope (UVOT). The central object of this nebula has previously been described as a late-type K giant barium star with a possible hot companion, most likely a young pre-white dwarf. UVOT photometry shows that while the optical photometry is consistent with a large cool object, the near-ultraviolet (UV) photometry shows far more UV flux than could be produced by any late-type object. Using model stellar atmospheres and a comparison to UVOT photometry for the pre-white dwarf PG 1159-035, we find that the companion has a temperature of at least 40,000 K and a radius of, at most, 0.056 R_sun. While the temperature and radius are consistent with a hot compact stellar remnant, they are lower and larger, respectively, than expected for a typical young pre-white dwarf. This likely indicates a deficiency in the assumed UV extinction curve. We find that higher temperatures more consistent with expectations for a pre-white dwarf can be derived if the foreground dust has a strong "blue bump" at 2175 AA and a lower R_V. Our results demonstrate the ability of Swift to both uncover and characterize hot hidden companion stars and to constrain the UV extinction properties of foreground dust based solely on UVOT photometry.Comment: 26 pages, 9 figure, accepted to Astronomical Journa

    Zooming in on zooming out: Partial selectivity and dynamic tuning of bilingual language control during reading

    Get PDF
    Available online 29 November 2019.Prominent models of bilingual visual word recognition posit a bottom-up nonselective view of lexical processing with parallel access to lexical candidates of both languages. However, these accounts do not accommodate recent findings of top-down effects on the relative global activation level of each language during bilingual reading. We conducted two eye-tracking experiments to systematically assess the degree of accessibility of each language in different global language contexts. When critical words were presented overtly in Experiment 1, code switches disrupted reading early during lexical processing, but not as much as pseudowords did. Participants zoomed out of the target language with increasing exposure to language switches. In Experiment 2, a monolingual language context was created by presenting critical words covertly as parafoveal previews. Here, code-switched words were treated like pseudowords, and participants remained zoomed in to the target language throughout the experiment. Switch direction analyses confirmed and extended these interpretations to provide further support for the role of global language control on lexical access, above and beyond effects due to proficiency differences across languages. Together, these data provide strong evidence for dynamic top-down adjustment of the degree of language selectivity during bilingual reading.This project was funded by awards from the National Institutes of Health (#1R0101HD073948; 11601946) and the UC Davis Graduate Studies Division of Social Sciences
