Fit to Print: Hudson’s Gentrification in the New York Times, 1985-2016
“Fit to Print: Hudson’s Gentrification in the New York Times, 1985-2016” is a content analysis of 80 New York Times articles that investigates the way that the City of Hudson N.Y. has been covered by the paper between 1985 and 2016. Findings from this content analysis are presented in 10-year increments. In the first phase of coverage, New York Times reporting primed Hudson for gentrification by depicting it as a site of urban decay hoping to revitalize. In the second phase (1997-2006) New York Times coverage promoted growth regime activities and minimized social problems in the city. In the last phase (2007-2016) the paper framed Hudson as a gentrified city now taken over by a creative class who see Hudson as an alternative to a larger urban center. Together, these findings show how a pro-gentrification narrative has been constructed by The Times and encourages further gentrification in the future
Adaptation to a Motion-Based and Non-Motion-Based Simulator
This study (N=129, including 59 males and 61 females) examined the issue of realism and motion sickness between motion-based and non-motionbased simulators. Specifically, this research address whether enhancing a driving simulator with motion capabilities increases the realism of the simulator and, if so, does this increase in subjective realism increase participants’ vulnerability to motion sickness. Approximately half of the participants drove a motion-based simulator while the other half drove a non-motion-based simulator on four independent drives within an experimental session. Results showed that the motion-based simulator was rated more realistic than the non-motion-based simulator. However, it was also found that participants in the motion-based simulator had higher negative physical health ratings than participants in the nonmotion-based simulator. Our results suggest that training programs need to consider the trade-off between realism and motion sickness
Applications of microcomputers in interactive image processing
Interactive image processing systems are reviewed and a system incorporating a charge coupled device imaging array, a microprocessor computing element, and a real time image display is described. Applications are given, including the description of a system capable of collecting multispectral images for satellite imagery calibration.
A new technique, called shift and add, which allows nearly diffraction limited images to be formed of objects viewed through a randomly distorted, turbulent media is formulated. The successful simulation of the method in an optical laboratory is reported. Results are given which show that if the method is applied in large telescope, optical astronomical imaging, nearly diffraction limited images may be obtained through the earth's atmosphere. It is shown that this can be achieved even though the telescope may have severe aberrations and when using a much wider bandwidth than that used at present in stellar Speckle Interferometry

Lactate, N-acetylaspartate, choline and creatine concentrations, and spin-spin relaxation in thalamic and occipito-parietal regions of developing human brain
Previous studies of the brains of normal infants demonstrated lower lactate (Lac)/choline (Cho), Lac/creatine (Cr), and Lac/ N-acetylaspartate (Naa) peak-area ratios in the thalamic region (predominantly gray matter) compared with occipitoparietal (mainly unmyelinated white matter) values. In the present study, thalamic Cho, Cr, and Naa concentrations between 32-42 weeks\u27 gestational plus postnatal age were greater than occipito-parietal: 4.6 +/- 0.8 (mean +/- SE), 10.5 +/- 2.0, and 9.0 +/- 0.7 versus 1.8 +/- 0.6, 5.8 +/- 1.5, and 3.4 +/- 1.1 mmol/kg wet weight, respectively: Lac concentrations were similar, 2.7 +/- 0.6 and 3.3 +/- 1.3 mmol/kg wet weight, respectively. In the thalamic region, Cho and Naa T2s increased, and Cho and Lac concentrations decreased, during development. Lower thalamic Lac peak-area ratios are principally due to higher thalamic concentrations of Cho, Cr, and Naa rather than less Lac. The high thalamic Cho concentration may relate to active myelination; the high thalamic Naa concentration may be due to advanced gray-matter development including active myelination. Lac concentration is higher in neonatal than in adult brain
Review of high-contrast imaging systems for current and future ground- and space-based telescopes I. Coronagraph design methods and optical performance metrics
The Optimal Optical Coronagraph (OOC) Workshop at the Lorentz Center in
September 2017 in Leiden, the Netherlands gathered a diverse group of 25
researchers working on exoplanet instrumentation to stimulate the emergence and
sharing of new ideas. In this first installment of a series of three papers
summarizing the outcomes of the OOC workshop, we present an overview of design
methods and optical performance metrics developed for coronagraph instruments.
The design and optimization of coronagraphs for future telescopes has
progressed rapidly over the past several years in the context of space mission
studies for Exo-C, WFIRST, HabEx, and LUVOIR as well as ground-based
telescopes. Design tools have been developed at several institutions to
optimize a variety of coronagraph mask types. We aim to give a broad overview
of the approaches used, examples of their utility, and provide the optimization
tools to the community. Though it is clear that the basic function of
coronagraphs is to suppress starlight while maintaining light from off-axis
sources, our community lacks a general set of standard performance metrics that
apply to both detecting and characterizing exoplanets. The attendees of the OOC
workshop agreed that it would benefit our community to clearly define
quantities for comparing the performance of coronagraph designs and systems.
Therefore, we also present a set of metrics that may be applied to theoretical
designs, testbeds, and deployed instruments. We show how these quantities may
be used to easily relate the basic properties of the optical instrument to the
detection significance of the given point source in the presence of realistic
noise.Comment: To appear in Proceedings of the SPIE, vol. 1069
A double-blind, randomized, multicenter, Italian study of frovatriptan versus almotriptan for the acute treatment of migraine
The objective of this study was to evaluate patients’ satisfaction with acute treatment of migraine with frovatriptan or almotriptan by preference questionnaire. One hundred and thirty three subjects with a history of migraine with or without aura (IHS 2004 criteria), with at least one migraine attack in the preceding 6 months, were enrolled and randomized to frovatriptan 2.5 mg or almotriptan 12.5 mg, treating 1–3 attacks. The study had a multicenter, randomized, double blind, cross-over design, with treatment periods lasting <3 months. At study end patients assigned preference to one of the treatments using a questionnaire with a score from 0 to 5 (primary endpoint). Secondary endpoints were pain free and pain relief episodes at 2 and 4 h, and recurrent and sustained pain free episodes within 48 h. Of the 133 patients (86%, intention-to-treat population) 114 of them expressed a preference for a triptan. The average preference score was not significantly different between frovatriptan (3.1 ± 1.3) and almotriptan (3.4 ± 1.3). The rates of pain free (30% frovatriptan vs. 32% almotriptan) and pain relief (54% vs. 56%) episodes at 2 h did not significantly differ between treatments. This was the case also at 4 h (pain free: 56% vs. 59%; pain relief: 75% vs. 72%). Recurrent episodes were significantly (P < 0.05) less frequent under frovatriptan (30% vs. 44%), also for the attacks treated within 30 min. No significant differences were observed in sustained pain free episodes (21% vs. 18%). The tolerability profile was similar between the two drugs. In conclusion, our study suggests that frovatriptan has a similar efficacy of almotriptan in the short-term, while some advantages are observed during long-term treatment
