Ambulatory assisted living fallers at greatest risk for head injury
No full textOBJECTIVES: To determine the relationship between head injuries sustained during each fall with various known high risk health and demographic factors predictive of falls.
DESIGN: Prospective cohort study conducted over 1 year
SETTING: Assisted living and skilled nursing units of a Continuing Care Retirement Community located in the northeastern United States.
PARTICIPANTS: Sixty nine OAs who fell.
MEASUREMENTS: Age, gender, diagnosis, high risk medication, functional, cognitive, ambulation/elimination status, mode of locomotion, fall related symptoms and the position of the fall, were analyzed using General Estimating Equations among elderly fallers with and without head injury.
RESULTS: A total of 173 falls (average of 2.9 times) were observed for 62 patients who had complete injury data. Injuries were recorded in 40.5% of falls, with 41.4% being head injuries. Head injuries were more likely to be hematomas than lacerations (66.7% vs. 14.7%) and among assisted living residents (p=0.04). Head injured patients were more likely to be walking at the time of the fall (69% vs. 36.1%) and less likely to have bowel incontinence (3.5% vs. 28.5%; p=0.04). None of the high risk diagnosis or medications associated with falls risk increased risk for head injury.
CONCLUSION: Those at greatest risk for head injury were ambulatory assisted living residents. None of the known clinical conditions predictive of risk to fall were predictive of head injury. For head injury prevention to be successful we need a closer examination of resident’s mobility, shoe-wear, health behavior with respect to ability to use assistive devices, and floor surface landing area. Future health policy implications include measures to ensure standard of care practices for head injured patients are in place.This is the peer reviewed version of the following article: Gray-Miceli, D.

An introduction to elementary particle phenomenology
No full textThis book deals with the development of particle physics, in particular through the exacting and all-important interplay between theory and experiment, an area that has now become known as phenomenology. Particle physics phenomenology provides the connection between the mathematical models created by theoretical physicists and the experimentalists who explore the building blocks of matter and the forces that operate between them. Assuming no more background knowledge than the basics of quantum mechanics, relativistic mechanics and nuclear physics, the author presents a solid and clear motivation for the developments witnessed by the particle physics community at both high and low energies over that last 50 or 60 years. In particular, the role of symmetries and their violation is central to many of the discussions. Including exercises and many references to original experimental and theoretical papers, as well as other useful sources, it will be essential reading for all students and researchers in modern particle physics
Stephen Hawking smoked my socks: how beliefs contaminate our opinions: an astrophysicist's perspective
No full text"Stephen Hawking Smoked My Socks is a prism-free lens with which forgotten basic skills in objectivity are seen again, and the innate art of existence is set free from the dictates of fear and power."
— Ian Campbell-Gillies
Why did Stephen Hawking become so famous? What exactly brought world renown to Albert Einstein? Why are those particular individuals household names across the globe whilst other achievers are not; why have they become icons to rival film stars; and why they are adored and protected by a fiercely loyal fan base? In Stephen Hawking Smoked My Socks, Hilton Ratcliffe seeks out the answers to those questions, and discovers that they have nothing at all to do with science
\u3ci\u3eCOLLAGENUS DASYSTERNUS\u3c/i\u3e, A NEW GENUS AND SPECIES OF DYNASTINAE FROM EASTERN VENEZUELA WITH A KEY TO THE NEW WORLD GENERA OF PENTODONTINI (COLEOPTERA: SCARABAEIDAE: DYNASTINAE)
No full textCollagenus dasysternus Ratcliffe and Hardy, new genus and species, is described from eastern Venezuela. We include a revised key to the 26 genera of New World Pentodontini. When the second author (Hardy) first saw this Venezuelan specimen in the Henry Howden collection, he could not readily place it to genus. When the first author (Ratcliffe) received the specimen from Hardy for examination in mid-2003, he was immediately taken with its gestalt similarity with the genus Coscinocephalus Prell that occurs in Arizona and Mexico. Unfortunately, there is only one specimen, but our examination revealed such unique character states that were indicative of a new, undescribed genus and species that we describe it here. We utilize the Phylogenetic Species Concept as outlined by Wheeler and Platnick (2000). This concept defines species as the smallest aggregation of sexual populations diagnosable by a unique combination of character states. Whether this species occurs rarely in nature remains unknown, but the area from which it was collected is readily accessible if someone wanted to make a concerted effort to find additional specimens. During a visit by one of us (Ratcliffe) to the extensive collections of the Universidad Central de Venezuela in Maracay in 1999, similar specimens were not found

Review of the genus Acrobolbia with remarks on its classification, and a key to the world genera of Cyclocephalini (Coleoptera: Scarabaeidae: Dynastinae)
No full textThe monotypic South American scarab genus Acrobolbia Ohaus, 1912 is reviewed and transferred to the tribe Cyclocephalini (Coleoptera: Scarabaeidae: Dynastinae). It was formerly placed in the subtribe Acrobolbiina (Rutelinae: Rutelini) or subtribe Oryctomorphina (Dynastinae: Pentodontini), depending on the author. We discuss characters that warrant transfer, redescribe the genus (including the first description of a female), and briefly discuss natural history of A, macrophylla Ohaus, 1912. We include a key to males and females of all 14 genera of Cyclocephalini.This research was supported by

Use of a comprehensive postfall assessment tool to prevent falls
No full textNursing research in fall prevention should not only identify etiologic risk factors to fall, but seek to identify underlying causes, whenever possible. Few studies have investigated the use of a comprehensive post fall assessment tool (PFAT) by nurses as an intervention for the prevention of recurrent falls, especially one that prompts nurses to consider all potential causes through a categorization scheme. This study tested use of a comprehensive PFAT as an intervention, prospectively, facility-wide for 1 year by RNs using a pre-post-test design. A 29.4% reduction in the fall rate (z=3.89; p <0.001), 27.6% decline in total falls experienced by all fallers (p<0.001) and a 34.0% decline for recurrent fallers (p = 0.025) from pre-intervention to intervention year was observed when trained nurses categorized falls according to perceived causes. These declines are likely due to consistent and rigorous use by trained nursing staff, prompting their critical examination of each fall.Peer reviewe
Can Expanding the Use of Computers Improve the Performance of Small Minority- and Women-Owned Enterprises?
No full textThis study aims at increasing our knowledge in this area by obtaining and analyzing new data to answer three key questions:
1. What performance and productivity gains are achieved when small businesses and minority- and women-owned enterprises (MWEs) implement information technology? What are the potential economic benefits of improving MWEs’ use of information technology?
2. What are the factors that lead some MWEs to take great advantage of computer technologies and that lead others to utilize computers only in a limited way? What are the barriers to MWEs’ adoption and effective use of technology? In particular, how significant are the impacts of constraints on capital, on knowledge of the technology and its possible role in improving businesses, and on the ability to train workers?
3. Is there a gap in computer use that separates small MWEs and small, white-male-owned enterprises? Are MWEs falling behind in adopting and implementing information technologies for important business functions?Originally published by The Urban Institute. Copyright © March 2004 The Urban Institute
Buckling tests of sandwich cylindrical shells with and without cut-outs
No full textThe results of buckling tests performed during the project DESICOS funded by the European Commission in the FP7 Programme are here presented. The tested structures are sandwich cylindrical shells that consist of reduced models of a component of the Ariane 5 launcher: the Dual Launch System. In particular, the scaled component is studied with and without the presence of cut-outs. Before performing the tests, the geometric imperfections as well as the thickness variations were measured. The tests were performed using the buckling testing equipment of Politecnico di Milano. The results of the tests contributed to understand the complex phenomenon of buckling of sandwich cylindrical shells, and to study the effect of initial geometric imperfections. They were also used to validate finite element models useful for the design of future launcher structures, and to set-up a probabilistic approach for the buckling analysis of cylindrical shells
