FERPA Close-Up: When Video Captures Violence and Injury

Federal privacy law is all to often misconstrued or perverted to preclude the disclosure of video recordings that capture students victimized by violent crime or tortious injury. This misuse of federal law impedes transparency and accountability and, in many cases, even jeopardizes the health, safety, and lives of children. When properly construed, however, federal law is no bar to disclosure and, at least in public schools, works in tandem with freedom of information laws to ensure disclosure. This Article posits that without unequivocal guidance from federal administrative authorities, uncertainty regarding the disclosure of such recordings will continue to linger, jeopardizing the ability of plaintiffs to access needed information

Urban Blasting Vibrations: Case Histories of Vibration Monitoring in New York City

This paper summarizes the monitoring experienced gained from several urban rock blasting projects in New York City and one just beyond the city limits. The majority of the experience was gained on the new South Ferry Terminal Structural Box project that included a new subway terminal station and section of tunnel on the number 1-line subway located in Battery Park in Lower Manhattan. The paper will review lessons learned and the limitations of using “off-the-shelf” seismographs for near-field blast monitoring. We allege that standard and widely available seismograph equipment is not generally utilized to its fullest potential, and that alternative forms of monitoring are often overlooked in favor of criteria based on peak particle velocity alone. The new South Ferry Terminal tunnel and station comprised a 1,300 ft long excavation varying in width from 25 to 60 ft and 20 to 50 ft in depth. The excavation necessitated blasting adjacent to and underneath existing subway lines at several locations. A separate project currently underway and at a site located north of New York City, is also mentioned due to its wider variation of blast parameters relative to the more typical “urban” blast projects of New York City

Stabilization and ribosome association of unspliced pre-mRNAs in a yeast upf1- mutant

Nonsense-mediated mRNA decay, the accelerated turnover of mRNAs transcribed from genes containing early nonsense mutations, is dependent on the product of the UPF1 gene in yeast. Mutations that inactivate UPF1 lead to the selective stabilization of mRNAs containing early nonsense mutations but have no effect on the half-lives of almost all other mRNAs. Since the transcripts of nonsense alleles are not typical cellular constituents, we sought to identify those RNAs that comprise normal substrates of the nonsense-mediated mRNA decay pathway. Many yeast pre-mRNAs contain early in-frame nonsense codons and we consider it possible that a role of this pathway is to accelerate the degradation of pre-mRNAs present in the cytoplasm. Consistent with this hypothesis, we find that, in a strain lacking UPF1 function, the CYH2, RP51B, and MER2 pre-mRNAs are stabilized 2- to 5-fold and are associated with ribosomes. We conclude that a major source of early nonsense codon-containing cytoplasmic transcripts in yeast is pre-mRNAs and that the UPF1 protein may be part of a cellular system that ensures that potentially deleterious nonsense fragments of polypeptides do not accumulate

Metabolic characteristics of human hearts preserved for 12 hours by static storage, antegrade perfusion, or retrograde coronary sinus perfusion

ObjectiveMachine perfusion of donor hearts is a promising strategy to increase the donor pool. Antegrade perfusion is effective but can lead to aortic valve incompetence and nonnutrient flow. Experience with retrograde coronary sinus perfusion of donor hearts has been limited. We tested the hypothesis that retrograde perfusion could support myocardial metabolism over an extended donor ischemic interval.MethodsHuman hearts from donors that were rejected or not offered for transplantation were preserved for 12 hours in University of Wisconsin Machine Perfusion Solution by: (1) static hypothermic storage; (2) hypothermic antegrade machine perfusion; or (3) hypothermic retrograde machine perfusion. Myocardial oxygen consumption (MVO2), and lactate accumulation were measured. Ventricular tissue was collected for proton and phosphorus 31 magnetic resonance spectroscopy (MRS) to evaluate the metabolic state of the myocardium. Myocardial water content was determined at the end of the experiment.ResultsStable perfusion parameters were maintained throughout the perfusion period with both perfusion techniques. Lactate/alanine ratios were lower in perfused hearts compared with static hearts (P < .001). Lactate accumulation (antegrade 2.0 ± 0.7 mM, retrograde 1.7 ± 0.1 mM) and MVO2 (antegrade 0.25 ± 0.2 mL, retrograde 0.26 ± 0.3 mL O2/min/100 g) were similar in machine-perfused groups. High-energy phosphates were better preserved in both perfused groups (P < .05). Left ventricular myocardial water content was increased in retrograde perfused hearts (80.2 ± 0.8%) compared with both antegrade perfused hearts (76.6 ± 0.8%, P = .02) and static storage hearts (76.7 ± 1%, P = .02).ConclusionsMachine perfusion by either the antegrade or the retrograde technique can support myocardial metabolism over long intervals. Machine perfusion seems promising for long-term preservation of human donor hearts

Orchestrating Tuple-based Languages

The World Wide Web can be thought of as a global computing architecture supporting the deployment of distributed networked applications. Currently, such applications can be programmed by resorting mainly to two distinct paradigms: one devised for orchestrating distributed services, and the other designed for coordinating distributed (possibly mobile) agents. In this paper, the issue of designing a pro- gramming language aiming at reconciling orchestration and coordination is investigated. Taking as starting point the orchestration calculus Orc and the tuple-based coordination language Klaim, a new formalism is introduced combining concepts and primitives of the original calculi. To demonstrate feasibility and effectiveness of the proposed approach, a prototype implementation of the new formalism is described and it is then used to tackle a case study dealing with a simplified but realistic electronic marketplace, where a number of on-line stores allow client applications to access information about their goods and to place orders

Evolution of dopant-induced helium nanoplasmas

Two-component nanoplasmas generated by strong-field ionization of doped helium nanodroplets are studied in a pump-probe experiment using few-cycle laser pulses in combination with molecular dynamics simulations. High yields of helium ions and a pronounced, droplet size-dependent resonance structure in the pump-probe transients reveal the evolution of the dopant-induced helium nanoplasma. The pump-probe dynamics is interpreted in terms of strong inner ionization by the pump pulse and resonant heating by the probe pulse which controls the final charge states detected via the frustration of electron-ion recombination

The Arkansas Proposal on Access to Court Records: Upgrading the Common Law with Electronic Freedom of Information Norms

The law and practice of court record access across United States jurisdictions is in a confused state. Public access to records in the hands of government, including court records, is a desirable norm of public policy; on this point, there is universal agreement. But there is disagreement on questions as fundamental as whether public access to court records is founded in constitutional law, or only in common law; and the extent to which court record access is the province of the courts or the legislature. And most importantly, there is widely divergent disagreement about what circumstances warrant restriction on public access to records. These disagreements and the attendant confusion in the law have been exacerbated in the electronic era, which has given rise to myriad concerns over access and privacy that are alien to the common law experience. The purposes of this Article are to review the development of court record access law from its common law origin through its confusing appearance in constitutional law in the company of its equally unsettled twin, courtroom access; to explicate the CCJ/COSCA Guidelines, developed to provide multi-jurisdictional guidance, and second, to provide a “legislative history” for, and an explication of, the Arkansas Proposed Order, with reference to its antecedents in common law, in the Guidelines, and in Arkansas FOI law; and to assess the extent to which the Proposed Order accords with and departs from critical FOI norms enshrined in the Arkansas FOIA, specifically with respect to seven issues we have identified as critical

An all-solid-state laser source at 671 nm for cold atom experiments with lithium

We present an all solid-state narrow line-width laser source emitting $670\,\mathrm{mW}$ output power at $671\,\mathrm{nm}$ delivered in a diffraction-limited beam. The \linebreak source is based on a fre-quency-doubled diode-end-linebreak pumped ring laser operating on the ${^4F}_{3/2} \rightarrow {^4I}_{13/2}$ transition in Nd:YVO$_4$. By using periodically-poled po-tassium titanyl phosphate (ppKTP) in an external build-up cavity, doubling efficiencies of up to 86% are obtained. Tunability of the source over $100\,\rm GHz$ is accomplished. We demonstrate the suitability of this robust frequency-stabilized light source for laser cooling of lithium atoms. Finally a simplified design based on intra-cavity doubling is described and first results are presented
