Contextual Adaptation. Human Functioning as Dynamic Interaction: A Social Work Perspective

Despite the recent development of theories in the social sciences that define human development and functioning in an integrated, nuanced and complex manner, the social work concept of “person-in-environment” remains outdated and limited. This is in part due to the “person” and “environment”--the biological, psychological, and social environments--being defined in distinction from one another. In order to remain current and effective in arguing on behalf of a clear professional voice in the field, social workers must not only engender but also promote a fundamental practice perspective that addresses complexity. A reformulation of “person-in-environment” can help social workers more fully realize the desire to unite under the common professional mandates requiring that both a “person-in-environment” perspective and a full biopsychosocial picture be taken into clinical accounts. To meet this aim I develop the concept of contextual adaptation, a new definition of “person-in-environment” reliant on tenets of nonlinear dynamic systems theory, specifically chaos theory. Nonlinear dynamic systems theory offers a unique opportunity for social workers to retain the core potentiality and utility of “person-in-environment,” that which enables them to account for the importance of environment, but reformulate it so as to create a more viable concept. Contextual adaptation is defined as a biopsychosocial process allowing for an integrated focus on the influence and management of the overlapping contexts of self, interpersonal experience, and sociocultural demands. Human development and functioning are established as a spectrum of adaptive behavior based on the regulation of the needs and requirements of internal processes, relational experience, and external influence

Marketization in Long-Term Care: A Cross-Country Comparison of Large For-Profit Nursing Home Chains.

This article presents cross-country comparisons of trends in for-profit nursing home chains in Canada, Norway, Sweden, United Kingdom, and the United States. Using public and private industry reports, the study describes ownership, corporate strategies, costs, and quality of the 5 largest for-profit chains in each country. The findings show that large for-profit nursing home chains are increasingly owned by private equity investors, have had many ownership changes over time, and have complex organizational structures. Large for-profit nursing home chains increasingly dominate the market and their strategies include the separation of property from operations, diversification, the expansion to many locations, and the use of tax havens. Generally, the chains have large revenues with high profit margins with some documented quality problems. The lack of adequate public information about the ownership, costs, and quality of services provided by nursing home chains is problematic in all the countries. The marketization of nursing home care poses new challenges to governments in collecting and reporting information to control costs as well as to ensure quality and public accountability

BioSAVE: display of scored annotation within a sequence context.

BACKGROUND: Visualization of sequence annotation is a common feature in many bioinformatics tools. For many applications it is desirable to restrict the display of such annotation according to a score cutoff, as biological interpretation can be difficult in the presence of the entire data. Unfortunately, many visualisation solutions are somewhat static in the way they handle such score cutoffs. RESULTS: We present BioSAVE, a sequence annotation viewer with on-the-fly selection of visualisation thresholds for each feature. BioSAVE is a versatile OS X program for visual display of scored features (annotation) within a sequence context. The program reads sequence and additional supplementary annotation data (e.g., position weight matrix matches, conservation scores, structural domains) from a variety of commonly used file formats and displays them graphically. Onscreen controls then allow for live customisation of these graphics, including on-the-fly selection of visualisation thresholds for each feature. CONCLUSION: Possible applications of the program include display of transcription factor binding sites in a genomic context or the visualisation of structural domain assignments in protein sequences and many more. The dynamic visualisation of these annotations is useful, e.g., for the determination of cutoff values of predicted features to match experimental data.

Mixing ratios of trace gases in the austral polar atmosphere during August and September of 1987

Mixing ratios are presented for a number of long-lived trace gases in the austral polar atmosphere during August and September of 1987. The recent discovery of a 12-year trend of increasing depletion of ozone over the Antarctic Continent in the spring of each year led to numerous theoretical interpretations and several scientific expeditions to the region. The results herein were obtained as part of a major effort involving penetration of the region of ozone depletion by NASA's multi-instrumented aircraft. One of the 14 instruments on the high-altitude ER-2 aircraft collected pressurized air samples between latitudes of 53 degrees and 72 degrees south at pressure altitudes up to 21 km in a series of 12 flights from Punta Arenas, Chile, over the Palmer Peninsula. The sampling system, located in the nose section of ER-2, has an inlet tube in the free airstream, a metal-bellows air pump, and 14 specially treated 1.6 l stainless-steel canisters for containing the pressurized air at 350 kPa. A typical flight profile consisted of a southbound path on the 428 K potential temperature surface, a descent to a pressure altitude of 13.7 km, a climb to the 460 K surface, and return on this surface. Mixing ratios for the trace gases were obtained from gas chromatographic analyses of the pressurized air samples. Of the species measured, the mixing ratios for CH4, CO, N2O, CF2 Cl2, CFCl3, CH3, CCl3, CCl4, and C2F3Cl3 are reported here
