Coverage Properties Of Optimized Confidence Intervals For Proportions

Wardell (1997) provided a method for constructing confidence intervals on a proportion that modifies the Clopper-Pearson (1934) interval by allowing for the upper and lower binomial tail probabilities to be set in a way that minimizes the interval width. This article investigates the coverage properties of these optimized intervals. It is found that the optimized intervals fail to provide coverage at or above the nominal rate over some portions of the binomial parameter space but may be useful as an approximate method

Competition In Urban Public Transport A World View

Over the past 15 years, a number of nations and urban areas have converted part or all of their public transport systems to competitive mechanisms. At the same time, the competitive market has provided public transport services in other nations for decades. This paper provides an international perspective on the current situation and developments in competitive provision of public transport services. Particular emphasis is placed upon the history of competitive provision in France, the international role of French companies in competition and the prospects for additional competition under new regulations of the European Union. Detailed case studies are provided dealing with urban areas, including London, Stockholm, Copenhagen, Denver, San Diego and Las Vega

Whole-Genome Gene Expression Profiling of Formalin-Fixed, Paraffin-Embedded Tissue Samples

We have developed a gene expression assay (Whole-Genome DASL®), capable of generating whole-genome gene expression profiles from degraded samples such as formalin-fixed, paraffin-embedded (FFPE) specimens.∼0.75 with standard FFPE inputs (200 ng).Taken together, these results show that WG-DASL assay provides a reliable platform for genome-wide expression profiling in archived materials. It also possesses utility within clinical settings where only limited quantities of samples may be available (e.g. microdissected material) or when minimally invasive procedures are performed (e.g. biopsied specimens)

The De-Icing Comparison Experiment (D-ICE): a study of broadband radiometric measurements under icing conditions in the Arctic

Surface-based measurements of broadband shortwave (solar) and longwave (infrared) radiative fluxes using thermopile radiometers are made regularly around the globe for scientific and operational environmental monitoring. The occurrence of ice on sensor windows in cold environments &ndash; whether snow, rime, or frost &ndash; is a common problem that is difficult to prevent as well as difficult to correct in post-processing. The Baseline Surface Radiation Network (BSRN) community recognizes radiometer icing as a major outstanding measurement uncertainty. Towards constraining this uncertainty, the De-Icing Comparison Experiment (D-ICE) was carried out at the NOAA Atmospheric Baseline Observatory in Utqiaġvik (formerly Barrow), Alaska, from August&nbsp;2017 to July&nbsp;2018. The purpose of D-ICE was to evaluate existing ventilation and heating technologies developed to mitigate radiometer icing. D-ICE consisted of 20&nbsp;pyranometers and 5&nbsp;pyrgeometers operating in various ventilator housings alongside operational systems that are part of NOAA's Barrow BSRN station and the US Department of Energy Atmospheric Radiation Measurement (ARM) program North Slope of Alaska and Oliktok Point observatories. To detect icing, radiometers were monitored continuously using cameras, with a total of more than 1&nbsp;million images of radiometer domes archived. Ventilator and ventilator&ndash;heater performance overall was skillful with the average of the systems mitigating ice formation 77&thinsp;% (many &gt;90&thinsp;%) of the time during which icing conditions were present. Ventilators without heating elements were also effective and capable of providing heat through roughly equal contributions of waste energy from the ventilator fan and adiabatic heating downstream of the fan. This provided &sim;0.6&thinsp;∘C of warming, enough to subsaturate the air up to a relative humidity (with respect to ice) of &sim;105&thinsp;%. Because the mitigation technologies performed well, a near complete record of verified ice-free radiometric fluxes was assembled for the duration of the campaign. This well-characterized data set is suitable for model evaluation, in particular for the Year of Polar Prediction (YOPP) first Special Observing Period (SOP1). We used the data set to calculate short- and long-term biases in iced sensors, finding that biases can be up to +60&thinsp;W&thinsp;m&minus;2 (longwave) and &minus;211 to +188&thinsp;W&thinsp;m&minus;2 (shortwave). However, because of the frequency of icing, mitigation of ice by ventilators, cloud conditions, and the timing of icing relative to available sunlight, the biases in the monthly means were generally less than the aggregate uncertainty attributed to other conventional sources in both the shortwave and longwave. &nbsp;</p

Effective Single-Parent Training Group Program: Three System Studies

Objective: This study highlights Dr. Elsie Pinkston and colleagues’ research on the effectiveness of behavior parent training and examines the application of single-parent training group (SPG) programs to three parent–child dyads exposed to distressed family circumstances. Methods: Single-system evaluation designs were conducted with two single birth parents, one single foster parent, and each parent’s three respective children, in an effort to appraise the results of a SPG program. Results: Two of the three parent–child dyads benefited from the SPG. Results suggested that there were changes in parent reinforcement and attention behaviors and children’s noncompliance behaviors. Conclusion: Behavioral improvements in single parent and child dyads lend support for the effectiveness of the parent training group for single parents. Implications for practice and future research on SPG programs are discussed

ABSTRACT: There is an urgent need to raise the incomes of urban residents in lower income nations. Effective transport can assist in this process by expanding the labor market available to workers. Some lowerincome nations seek to emulate public transport strategies from high-income urban areas. These strategies, however, have produced counterproductive results. Lower-income urban areas would do well to focus on less expensive strategies that expand mobility and access for larger numbers of people
