Degeneracy between mass and spin in black-hole-binary waveforms

We explore the degeneracy between mass and spin in gravitational waveforms emitted by black-hole binary coalescences. We focus on spin-aligned waveforms and obtain our results using phenomenological models that were tuned to numerical-relativity simulations. A degeneracy is known for low-mass binaries (particularly neutron-star binaries), where gravitational-wave detectors are sensitive to only the inspiral phase, and the waveform can be modelled by post-Newtonian theory. Here, we consider black-hole binaries, where detectors will also be sensitive to the merger and ringdown, and demonstrate that the degeneracy persists across a broad mass range. At low masses, the degeneracy is between mass ratio and total spin, with chirp mass accurately determined. At higher masses, the degeneracy persists but is not so clearly characterised by constant chirp mass as the merger and ringdown become more significant. We consider the importance of this degeneracy both for performing searches (including searches where only non-spinning templates are used) and in parameter extraction from observed systems. We compare observational capabilities between the early (~2015) and final (2018 onwards) versions of the Advanced LIGO detector.Comment: 11 pages, 9 figure

Analysis of Landlord/Tenant Wediation & Disparate Impact Towards Low-income People

This study examines the mediation as a means to settle landlord and tenant disputes and to discover if it is a just process for low-income people. Justice is defined as a process and principal by which each individual is assured the things that belong to him. One hundred subjects participated in mediation. The experimental group received training in landlord/tenant defenses prior to mediation while the control group went directly to mediation. Outcomes were measured for the experimental group, the control group, tenants going directly before the judge, and those with legal representation. These is no supporting evidence showing that justice was being served to low-income people. There was no significant difference in the outcome for tenants in the experimental and the control group.Master'sCollege of Arts and Sciences: Public AdministrationUniversity of Michiganhttp://deepblue.lib.umich.edu/bitstream/2027.42/117722/1/Baird.pd

Communication Correlates of Employee Morale

Although several factors are related to employee morale in organiza tional settings, the single most influential factor in enhancing job satis faction and group cohesiveness is superior-subordinate communication. Yet, while a great deal of speculation exists concerning the sorts of com munication behaviors most conducive to employee satisfaction, no em pirical test has been conducted to assess specifically the relationship between communication and morale. This study undertakes such an investigation.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/68753/2/10.1177_002194367801500306.pd

Research priorities for the management of broken bones of the upper limb in people over 50: A UK priority setting partnership with the James Lind Alliance

Objective. To determine research priorities for the management of broken bones of the upper limb in people over 50 which represent the shared priorities of patients, their families, carers and healthcare professionals. Design/setting. A national (UK) research priority-setting partnership. Participants. People aged 50 and over who have experienced a fracture of the upper limb; carers involved in their care; family and friends of patients; healthcare professionals involved in the treatment of these patients. Methods. Using a multiphase methodology in partnership with the James Lind Alliance over 15 months (September 2017 – December 2018), a national scoping survey asked respondents to submit their research uncertainties. These were amalgamated into a smaller number of research questions. The existing evidence was searched to ensure that the questions had not already been answered. A second national survey asked respondents to prioritise the research questions. A final shortlist of 25 questions was taken to a multistakeholder workshop where a consensus was reached on the top 10 priorities. Results. There were 1898 original uncertainties submitted by 328 respondents to the first survey. These original uncertainties were refined into 51 research questions of which 50 were judged to be true uncertainties following a review of the research evidence. There were 209 respondents to the second (interim prioritisation) survey. The top 10 priorities encompass a broad range of uncertainties in management and rehabilitation of upper limb fractures. Conclusions. The top 10 UK research priorities highlight uncertainties in how we assess outcomes, provide information, achieve pain control, rationalise surgical intervention, optimise rehabilitation and provide psychological support. The breadth of these research areas highlights the value of this methodology. This work should help to steer research in this area for the next 5-10 years and the challenge for researchers now is to refine and deliver answers to these research priorities
