Prosthesis coupling

A coupling for use in an apparatus for connecting a prosthesis to the bone of a stump of an amputated limb is described which permits a bio-compatible carbon sleeve forming a part of the prosthesis connector to float so as to prevent disturbing the skin seal around the carbon sleeve. The coupling includes a flexible member interposed between a socket that is inserted within an intermedullary cavity of the bone and the sleeve. A lock pin is carried by the prosthesis and has a stem portion which is adapted to be coaxially disposed and slideably within the tubular female socket for securing the prosthesis to the stump. The skin around the percutaneous carbon sleeve is able to move as a result of the flexing coupling so as to reduce stresses caused by changes in the stump shape and/or movement between the bone and the flesh portion of the stump

Marine Ecology Progress Series, 631, (2019): 1-17, doi:10.3354/meps13180.Knowledge about marine mammal habitat use is necessary for informing ecosystem-based management and mitigating human impacts. Massachusetts Bay is an important marine mammal foraging area in the Gulf of Maine and an area of substantial human activity, but delphinid habitat use is poorly understood. The goals of this work were to (1) document temporal and spatial occurrence of delphinid species in Massachusetts Bay using passive acoustic monitoring from ocean gliders and (2) explore the potential influences of environmental conditions on delphinid distributions. Gliders were deployed in late fall and early winter of 2014 and 2015-2016 and were equipped with a digital acoustic recorder and conductivity-temperature-depth instrument. Gliders surveyed an area of approximately 1000 km2. Delphinid whistles were detected on 93 of 128 (73%) deployment days. Animals were detected more often at night. Presence was consistent over 2 years, although detection rates showed annual and monthly variability. Spatial distribution differed between years, but most detections occurred close to Stellwagen Bank. Visual assessment of spectrograms suggests the presence of 2 species, Atlantic white-sided dolphins and common dolphins. The reoccurrence of 2 probable signature whistles over several weeks and consecutive winter seasons suggests prolonged occupancy during winter and possible annual site fidelity. These data show a consistent and frequent presence of delphinids near a known marine mammal foraging area (Stellwagen Bank) during late fall and winter and are a first step towards understanding both how odontocetes influence the Massachusetts Bay/Gulf of Maine ecosystem and how they may be impacted by human activities.We gratefully acknowledge the NOAA Northeast Fisheries Science Center, Stellwagen Bank National Marine Sanctuary, The Nature Conservancy, Massachusetts Division of Marine Fisheries, and the University of Massachusetts Dartmouth for their collaboration and support for this project.

“I one-hundred thousand percent blame it on QAnon”: The impact of QAnon belief on interpersonal relationships

Conspiracy beliefs have been found to have negative real-world consequences that can impact interpersonal relationships; however, this remains an under-researched area. With the current popularity of conspiracy movements such as QAnon, more research into these phenomena is necessary. The present research therefore aimed to explore the impact of QAnon belief on interpersonal relationships. Fifteen participants aged 21–54 (M = 41) with a QAnon-affiliated loved one were interviewed about how QAnon has changed their relationship. Using thematic analysis, four main themes were identified: Malignant Q, Distance, Qonflict, and Attempts at Healing. Participants characterized QAnon as a malignant force in their relationships and communicated with their loved ones less as a result. Although QAnon was a source of conflict and tension for all participants, they were motivated to understand their loved ones. Most participants who still had relationships with their loved ones were motivated to heal or maintain their relationships, while those who no longer did had previously tried many different strategies to save their relationships. These findings provide greater insight into how QAnon can impact relationships, offering fruitful directions for future research examining how individuals can heal from QAnon-afflicted relationships

Introduction: Contemporary developments in games teaching

For individuals interested in contemporary physical education and sports coaching practices, the well-known saying, 'may you live in interesting times' (sometimes referred to as the Chinese curse) will hold some resonance. As debate occurs about the very nature of what constitutes physical education and sports coaching, and 'which' knowledge should be privileged through pedagogical encounters, we do live in interesting times characterised by profound social and cultural changes (Wright, Macdonald and Burrows 2004). For some, these changes have produced professional working lives that are extremely fast-paced and time-poor. With many commercial enterprises claiming to offer 'innovative' and 'cutting-edge' practical solutions and 'quick fixes' for highly complex problems, as professionals we are now required to become critical consumer of what others have termed the global information explosion (Wright et. al. 2004). In relation to physical education and coaching we believe that in order to be effective critical consumers, 'context' matters and as such, we need local, nuanced examples of how various teaching coaching approaches are applied to consider their relevance for the issues we face in our own practice

Stories from the Rubble: Analysis of Mortuary Artifacts from the Spring Street Presbyterian Church Vaults

Archaeological investigations of the Spring Street Presbyterian Church vaults resulted in the recovery of coffin plates, hardware and other burial-related artifacts that convey information regarding the individuals interred within these chambers. These interments also offer a glimpse at mortuary customs and practices in vault burials during the first half of the 19th century

Masses, luminosities and dynamics of galactic molecular clouds

Star formation in galaxies takes place in molecular clouds and the Milky Way is the only galaxy in which it is possible to resolve and study the physical properties and star formation activity of individual clouds. The masses, luminosities, dynamics, and distribution of molecular clouds, primarily giant molecular clouds in the Milky Way are described and analyzed. The observational data sets are the Massachusetts-Stony Brook CO Galactic Plane Survey and the IRAS far IR images. The molecular mass and infrared luminosities of glactic clouds are then compared with the molecular mass and infrared luminosities of external galaxies
