The impact of information and communication technology on family carers of older people and professionals in Sweden

Government policy in Sweden, as in other developed countries, pays increasing attention as to how best to support the family carers of older people. New and innovative means of support, such as information and communication technology, are emerging. This paper explores the perceived benefits of, and barriers to, information technology as a means of supporting family carers of older people. Following a brief overview of the care-giving literature, with particular reference to the Swedish context, interview and questionnaire data collected from 34 families who took part in the Swedish ACTION project are used to explore the role of user-friendly information and communication technology to inform and enable family carers of older people to exercise choice, to care more effectively and to work in partnership with professionals. Interview data from two groups of professionals that utilised ACTION are also examined to throw light on its potential benefits for both carers and professionals. Consideration is given to the barriers to using information technology, and to identifying those carers most likely to benefit. Areas for further development are the need for practitioners' education and a wider range of programmes to address carers' diverse needs. Clearly, lessons learned from the Swedish project have wider relevance, given that new forms of support are being developed in most technically advanced countries

Pathologic manifestations of levamisole-adulterated cocaine exposure.

UnlabelledRheumatic manifestations of cocaine have been well described, but more recently, a dramatic increase in the levamisole-adulterated cocaine supply in the United States has disclosed unique pathologic consequences that are distinct from pure cocaine use. Most notably, patients show skin lesions and renal dysfunction in the setting of extremely high perinuclear anti-neutrophil cytoplasmic antibodies (p-ANCA). Unexpectedly, antibodies to myeloperoxidase, the typical target of p-ANCA, are relatively low if at all present. This discrepancy is due to the fact that p-ANCA seen in association with levamisole-adulterated cocaine exposure is often directed against atypical p-ANCA-associated antigens within the neutrophil granules such as human neutrophil elastase, lactoferrin, and cathepsin G. Biopsies of the skin lesions reveal leukocytoclastic vasculitis often involving both superficial and deep dermal vessels. Renal injury most typically manifests as crescentic and necrotizing pauci-immune glomerulonephritis. In this review, the manifestations of levamisole-adulterated cocaine-induced vasculitis are discussed with an emphasis on the typical histomorphologic findings seen on biopsy.Virtual slidesThe virtual slide(s) for this article can be found here: http://www.diagnosticpathology.diagnomx.eu/vs/1764738711370019

The nurses that roared: nurses from history who found their voices and challenged the status quo

In this article we explore how nurses from history challenged norms of nursing and society, and consider how they can influence and inspire nurses today. We discuss the role of nurses in the fight for women’s suffrage, campaigning for the vote and caring for women who suffered in their fight to achieve it, and present examples of outstanding bravery in the past and present day. The article contains examples of the bravery of some relatively unknown nurses in wartime, who also fought for equality and inclusion, and nurses who challenged the care of marginalised groups, campaigning for improved treatment, sometimes at great personal cost. Finally we consider the courage of present-day nurses. Drawing on the global campaign of “Nursing Now”, we suggest that learning from these exceptional nurses and acknowledging and highlighting their contribution can inspire us to strengthen and promote nursing and to empower women globally

Spectral determinations for discrete sources with EGRET

The ability of the EGRET (Energetic Gamma-Ray Experimental Telescope) to determine the spectral parameters of point sources in 14-day exposures, as planned for the initial survey phase of the GRO (Gamma Ray Observatory) mission, is explored by numerical simulation. Results are given for both galactic and extragalactic objects as a function of source strength and for representative levels of diffuse background emission

Federal Military Agencies, 1861-1865

The Civil War in the United States was a gigantic moral and physical effort that has elicited the feelings of hundreds of its participants and thousands of its students. Yet, in all of the treatment of the conflict, a dearth of information is available on the informational agencies that contributed to the Union military victory. No historian to date has chosen to publish a definitive study of these agencies and it is the hope here that some light can be shed on four types of organizations that were, for the most part, developed as a result of the war. This paper deals only with the evolution of these units, their organization and personnel, and the ways in which they carried out their duties and the devices used. To get a clearer picture of the major organization, The United States Signal Corps, use has been made via microfilm of the letters sent from the Official of the Signal Officer, 1861 and 1862, and the original manuscript of letters written in the field by Colonel Myer during the Peninsular Campaign. When considering this thesis one definition should be kept in mind. The term Federal military information refers to any information of a military nature, or of significance to the military, both for land army or naval use, for its operations against the Southern Confederacy

Effects of Equal Periods of Massed Exposure versus Distributed Exposure to Systematic Exercises on the Physical Fitness of Fifth and Sixth Grade Boys

It was the intent of this study to investigate the effect of varied proportions of physical exercise equated in type and duration, on two equated groups of fifth and sixth grade boys

A Theoretical Trade-Off Between Wave Drag and Sonic Boom Loudness Due to Equivalent Area Changes on a Supersonic Body

The NASA University Leadership Initiative (ULI) titled ”Adaptive Aerostructures for Revolutionary Civil Supersonic Transportation” consists of a team of university and industry partners studying the feasibility of reducing the perceived loudness of the sonic boom by introducing an adaptive geometry at localized regions of an aircraft’s outer-mold line. The Utah State University AeroLab is a member of this ULI team and has produced low-fidelity tools to predict the aerodynamic and boom loudness effects from localized changes to the geometry. Such changes to the geometry affect both the sonic boom loudness and wave drag; however, the precise relationship between boom loudness and wave drag is not well understood for a morphing supersonic geometry. The current work utilizes an equivalent area approach and expresses this equivalent area using a Fourier sine series. An optimization routine was used to search for the Fourier coefficients that produce a minimum perceived level of decibels of the sonic boom for an optimized equivalent area distribution. The results for each candidate are compared against the Sears-Haack’s equivalent area, ground pressure signature, perceived noise, and wave drag. These tools were used to obtain a Pareto front of solutions to better understand the theoretical trade-off between wave drag and perceived noise on the ground as equivalent area changes on a supersonic geometry
