Doctrinal Antithesis in Anglo-American Administrative Law
English administrative law guards judicial supremacy over all matters of statutory interpretation, while instructing judges to refrain from scrutinizing administrators’ factual findings. By contrast, American federal courts are obliged to respect agencies’ statutory-interpretive autonomy, but take a rigorous “hard look” at substantial agency factual determinations. This Article argues that the antithetical approaches to judicial review of administrative action adopted by the apex courts of the United Kingdom and the United States can be adequately explained by the polarization of these two polities along a spectrum of effective vetogates.published_or_final_versio
The Politics of Constitutional Common Law in Hong Kong under Chinese Sovereignty
This article studies how the Hong Kong Court of Final Appeal has come to develop a sophisticated judicial gloss on the provisions of the Basic Law, Hong Kong’s constitutional document, in ways unforeseen by the Chinese National People’s Congress that enacted it. The ascendancy of constitutional common law in Hong Kong after the end of British rule is remarkable when considered in light of the continuing denial of democratic self-rule by China’s authoritarian Party-state. This article argues that the profusion of political transaction costs due to the fragmentation of the ruling elite and state-society discord consequent to the resumption of Chinese sovereignty has created the requisite space for the Court to craft, with impunity, consequential yet politically realistic doctrines bearing on such weighty matters as constitutional interpretation, central-local relations, separation of powers, and rights protection
Pharmacy Students’ Performance and Perceptions in a Flipped Teaching Pilot on Cardiac Arrhythmias
Objective. To implement the flipped teaching method in a 3-class pilot on cardiac arrhythmias and to assess the impact of the intervention on academic performance and student perceptions.
Design. An intervention group of 101 first-year pharmacy students, who took the class with the flipped teaching method, were supplied with prerecorded lectures prior to their 3 classes (1 class in each of the following subjects: basic sciences, pharmacology, and therapeutics) on cardiac arrhythmias. Class time was focused on active-learning and case-based exercises. Students then took a final examination that included questions on cardiac arrhythmias. The examination scores of the intervention group were compared to scores of the Spring 2011 control group of 105 first-year students who took the class with traditional teaching methods. An online survey was conducted to assess student feedback from the intervention group.
Assessment. The mean examination scores of the intervention group were significantly higher than the mean examination scores of the control group for the cardiac arrhythmia classes in pharmacology (with 89.6 6 2.0% vs 56.8 6 2.2%, respectively) and therapeutics (89.2 6 1.4% vs 73.7 6 2.1%, respectively). The survey indicated higher student satisfaction for flipped classes with highly rated learning objectives, recordings, and in-class activities.
Conclusion. Use of the flipped teaching method in a 3-class pilot on cardiac arrhythmias improved examination scores for 2 of the 3 classes (pharmacology and therapeutics). Student satisfaction was influenced by the quality of the learning objectives, prerecorded lectures, and inclass active-learning activities
Standardized Field Sobriety Test: False Positive Test Rate among Sober Subjects
The Standardized Field Sobriety Test (SFST) is a series of exercises that a law enforcement officer gives to a driver suspected of driving under the influence of alcohol. The original research that demonstrated a high correlation between failure of the SFST and a high blood alcohol concentration did not utilize a standard control group to validate that the failure of the SFST was not a characteristic of the population at large. This study examined a series of drug naive subjects to determine the rate of failure of the SFST to accurately distinguish a suspect with high blood alcohol content from the general public. Of the 185 subjects tested, 26% of the drug naïve subjects failed the SFST
Implementation of an Accelerated Physical Examination Course in a Doctor of Pharmacy Program
Objective. To describe the implementation of a 1-day accelerated physical examination course for a doctor of pharmacy program and to evaluate pharmacy students’ knowledge, attitudes, and confi- dence in performing physical examination.
Design. Using a flipped teaching approach, course coordinators collaborated with a physician faculty member to design and develop the objectives of the course. Knowledge, attitude, and confidence survey questions were administered before and after the practical laboratory.
Assessment. Following the practical laboratory, knowledge improved by 8.3% (p,0.0001). Students’ perceived ability and confidence to perform a physical examination significantly improved (p,0.0001). A majority of students responded that reviewing the training video (81.3%) and reading material (67.4%) prior to the practical laboratory was helpful in learning the physical examination.
Conclusion. An accelerated physical examination course using a flipped teaching approach was successful in improving students’ knowledge of, attitudes about, and confidence in using physical examination skills in pharmacy practice
Towards Efficient Detection of Small Near-Earth Asteroids Using the Zwicky Transient Facility (ZTF)
We describe ZStreak, a semi-real-time pipeline specialized in detecting
small, fast-moving near-Earth asteroids (NEAs) that is currently operating on
the data from the newly-commissioned Zwicky Transient Facility (ZTF) survey.
Based on a prototype originally developed by Waszczak et al. (2017) for the
Palomar Transient Factory (PTF), the predecessor of ZTF, ZStreak features an
improved machine-learning model that can cope with the data rate
increment between PTF and ZTF. Since its first discovery on 2018 February 5
(2018 CL), ZTF/ZStreak has discovered confirmed new NEAs over a total of
232 observable nights until 2018 December 31. Most of the discoveries are small
NEAs, with diameters less than m. By analyzing the discovery
circumstances, we find that objects having the first to last detection time
interval under 2 hr are at risk of being lost. We will further improve
real-time follow-up capabilities, and work on suppressing false positives using
deep learning.Comment: PASP in pres
A Twilight Search for Atiras, Vatiras, and Co-orbital Asteroids: Preliminary Results
Near-Earth objects (NEOs) that orbit the Sun on or within Earth's orbit are tricky to detect for Earth-based observers due to their proximity to the Sun in the sky. These small bodies hold clues to the dynamical history of the inner solar system as well as the physical evolution of planetesimals in extreme environments. Populations in this region include the Atira and Vatira asteroids, as well as Venus and Earth co-orbital asteroids. Here we present a twilight search for these small bodies, conducted using the 1.2 m Oschin Schmidt and the Zwicky Transient Facility (ZTF) camera at Palomar Observatory. The ZTF twilight survey operates at solar elongations down to 35° with a limiting magnitude of r = 19.5. During a total of 40 evening sessions and 62 morning sessions conducted between 2018 November 15 and 2019 June 23, we detected six Atiras, including two new discoveries, 2019 AQ₃ and 2019 LF₆, but no Vatiras or Earth/Venus co-orbital asteroids. NEO population models show that these new discoveries are likely only the tip of the iceberg, with the bulk of the population yet to be found. The population models also suggest that we have only detected 5%–7% of the H < 20 Atira population over the seven month survey. Co-orbital asteroids are smaller in diameter and require deeper surveys. A systematic and efficient survey of the near-Sun region will require deeper searches and/or facilities that can operate at small solar elongations
Observational and Dynamical Characterization of Main-Belt Comet P/2010 R2 (La Sagra)
We present observations of comet-like main-belt object P/2010 R2 (La Sagra)
obtained by Pan-STARRS 1 and the Faulkes Telescope-North on Haleakala in
Hawaii, the University of Hawaii 2.2 m, Gemini-North, and Keck I telescopes on
Mauna Kea, the Danish 1.54 m telescope at La Silla, and the Isaac Newton
Telescope on La Palma. An antisolar dust tail is observed from August 2010
through February 2011, while a dust trail aligned with the object's orbit plane
is also observed from December 2010 through August 2011. Assuming typical phase
darkening behavior, P/La Sagra is seen to increase in brightness by >1 mag
between August 2010 and December 2010, suggesting that dust production is
ongoing over this period. These results strongly suggest that the observed
activity is cometary in nature (i.e., driven by the sublimation of volatile
material), and that P/La Sagra is therefore the most recent main-belt comet to
be discovered. We find an approximate absolute magnitude for the nucleus of
H_R=17.9+/-0.2 mag, corresponding to a nucleus radius of ~0.7 km, assuming an
albedo of p=0.05. Using optical spectroscopy, we find no evidence of
sublimation products (i.e., gas emission), finding an upper limit CN production
rate of Q_CN<6x10^23 mol/s, from which we infer an H2O production rate of
Q_H2O<10^26 mol/s. Numerical simulations indicate that P/La Sagra is
dynamically stable for >100 Myr, suggesting that it is likely native to its
current location and that its composition is likely representative of other
objects in the same region of the main belt, though the relatively close
proximity of the 13:6 mean-motion resonance with Jupiter and the (3,-2,-1)
three-body mean-motion resonance with Jupiter and Saturn mean that dynamical
instability on larger timescales cannot be ruled out.Comment: 23 pages, 13 figures, accepted for publication in A
