Excess comovement in credit default swap markets: Evidence from the CDX indices

We provide evidence of excess comovement in the credit default swap (CDS) market following inclusions to and exclusions from investment grade and high yield CDX indices during the 2003–2016 period. We find that when a name joins an index, its return tends to covary more with the returns of that index and conversely when it is excluded from an index, its return tends to covary less with it. We use univariate regressions and a difference-in-difference approach to show that the CDS market is impacted by indexation. This excess comovement indicates a departure from fundamental-based pricing and provides support in favour of style investing

Talented and gifted language arts/reading curriculum for a rural school, grades K-4: Goals, objectives, and suggested implementation

As a result of the new Iowa Standards {1988), It has become necessary for all schools ln Iowa to establish programs for gifted and talented students systemwide. This required the Missouri Valley, Iowa, School District to develop an adequate and appropriate program to serve the needs of its identified gifted students

Internal velocity factors

Computer program analyzes the entries and planetary trajectories of space vehicles. It obtains the equivalence of altitude and flight path angle, respectively, to acceleration load factor with respect to velocity for a given inertial velocity

Concept definition study for recovery of tumbling satellites. Volume 1: Executive summary, study results

The first assessment is made of the design requirements and conceptual definition of a front end kit to be transported on the currently defined Orbital Maneuvering Vehicle (OMV) and the Space Transportation System Shuttle Orbiter, to conduct remote, teleoperated recovery of disabled and noncontrollable, tumbling satellites. Previous studies did not quantify the dynamic characteristics of a tumbling satellite, nor did they appear to address the full spectrum of Tumbling Satellite Recovery systems requirements. Both of these aspects are investigated with useful results

Concept definition study for recovery of tumbling satellites. Volume 2: Supporting research and technology report

A number of areas of research and laboratory experiments were identified which could lead to development of a cost efficient remote, disable satellite recovery system. Estimates were planned of disabled satellite motion. A concept is defined as a Tumbling Satellite Recovery kit which includes a modular system, composed of a number of subsystem mechanisms that can be readily integrated into varying combinations. This would enable the user to quickly configure a tailored remote, disabled satellite recovery kit to meet a broad spectrum of potential scenarios. The capability was determined of U.S. Earth based satellite tracking facilities to adequately determine the orientation and motion rates of disabled satellites

Zirconium metal-water oxidation kinetics. I. Thermometry

A description is given of the thermometry techniques used in the Zirconium Metal--Water Oxidation Kinetics Program. Temperature measurements in the range 900 to 1500$sup 0$C are made in three experimental systems: two oxidation apparatuses and the annealing furnace used in a corollary study of the diffusion of oxygen in $beta$-Zircaloy. Carefully calibrated Pt vs Pt--10 percent Rh thermocouples are employed in all three apparatuses, while a Pt--6 percent Rh vs Pt-- 30 percent Rh thermocouple and an optical pyrometer are used in addition in the annealing furnace. Features of the experimental systems pertaining to thermocouple installation, temperature control, emf measurements, etc. are described, and potential temperature-measurement error sources are discussed in detail. The accuracy of the temperature measurements is analyzed

Is the Toxicity of Salvage Prostatectomy Related to the Primary Prostate Cancer Therapy Received?

PURPOSE: To compare the toxicity profile and oncological outcome of salvage radical prostatectomy (SRP) following focal therapy (FT) versus SRP after radiation therapies (RT) - external beam radiation therapy (EBRT) or brachytherapy (BT). MATERIALS AND METHODS: Data concerning all men undergoing SRP for recurrent prostate cancer after either FT, EBRT or BT were retrospectively collected from 4 high volume surgical centres. The primary outcome measure of the study was toxicity of SRP characterized by any 30-day post-operative Clavien-Dindo complication rate, 12-month continence rate and 12-month potency rate. The secondary outcome was oncological outcome after SRP including positive margin rate and 12-month biochemical recurrence (BCR) rate. BCR was estimated using Kaplan-Meier methods and significant differences were calculated using a log rank test. Median follow-up time was 29.5 months. RESULTS: Between April 2007 and September 2018, 185 patients underwent SRP of which 95 had SRP after FT and 90 had SRP after RT, either EBRT or BT. SRP after RT was associated with a significantly higher 30-day Clavien-Dindo I-IV complication rate (34% vs 5%, p<0.001). At 12 months following surgery, patients undergoing SRP after FT had significantly better continence (SRP after FT:83% pad-free vs RT:49%) while potency outcomes were similar (FT:14% vs RT:11%). Men undergoing SRP after RT had a significantly higher stage and grade of disease together with a higher positive surgical margin rate (37% vs 13%, p=0.001). 3-year BCR after FT was 35% compared to 32% after RT, p=0.76. In multivariable analysis, men undergoing SRP after FT experienced a higher risk of BCR (HR 0.36 [0.18-0.82], p<0.005). CONCLUSIONS: This multicentre study demonstrates the toxicity of SRP in terms of perioperative complications and long-term urinary continence recovery is dependent on initial primary prostate cancer therapy received with men undergoing SRP after FT experiencing lower postoperative complication rates and better urinary continence outcomes
