Cruel Britannia: a personal critique of nursing in the United Kingdom
The United Kingdom (UK) once led the world in nursing but because of the exigencies of the funding mechanisms of the National Health Service (NHS), it has fallen a long way behind other countries. We aim to raise awareness inside and outside the UK about the decline in nursing as a profession there. We are purposely contentious, in an attempt to raise questions, both for the UK and for countries which are recruiting British nurses who are leaving because of job losses caused by the funding crisis in the NHS. This paper discusses where the problems that have led to the decline have come from, where nursing is going and poses questions for the future. We hope that the UK government and those who influence the development of nursing will bring it back to the standard it once bad
Autism and Computer Assisted Learning
Autism is a learning and social disorder that has seen increased diagnosis within school-age populations. As educators grapple with overwhelmed and understaffed classrooms, finding ways to address the educational needs of this particular population can be very challenging. However, technology may serve to create alternative “virtual” world opportunities and thus, begin to expand learning possibilities for these students
Development of kelp rockfish, Sebastes atrovirens (Jordan and Gilbert 1880), and brown rockfish, S. auriculatus (Girard 1854), from birth to pelagic juvenile stage, with notes on early larval development of black-and-yellow rockfish, S. chrysomelas (Jordan and Gilbert 1880), reared in the laboratory (Pisces: Sebastidae).
Larval kelp (Sebastes atrovirens), brown (S. auriculatus), and blackand-yellow (S. chrysomelas) rockfish were reared from known adults, to preflexion stage, nine days after birth for S. chrysomelas, to late postflexion stage for S. atrovirens, and to pelagic juvenile stage for S.
auriculatus. Larval S. atrovirens and S. chrysomelas
were about 4.6 mm body length (BL) and S. auriculatus about 5.2 mm BL at birth. Both S. atrovirens and S. auriculatus
underwent notochord flexion at about 6–9 mm BL. Sebastes atrovirens transform to the pelagic juvenile stage at about 14–16 mm BL and S. auriculatus transformed at ca. 25 mm BL. Early larvae of all three species were characterized by melanistic pigment dorsally on the head, on the gut, on most of the ventral margin of the tail, and in a long series on the dorsal margin of the tail. Larval S. atrovirens and S. auriculatus developed a posterior bar on the tail during the flexion or postflexion stage. In S. atrovirens xanthic pigment resembled the melanistic pattern throughout larval development. Larval S. auriculatus lacked
xanthophores except on the head until late preflexion stage, when a pattern much like the melanophore pattern gradually developed. Larval S. chrysomelas had extensive xanthic pigmentation dorsally, but none ventrally, in preflexion stage. All members of the Sebastes subgenus
Pteropodus (S. atrovirens, S. auriculatus, S. carnatus, S. caurinus, S. chrysomelas, S. dalli, S. maliger, S. nebulosus, S. rastrelliger) are morphologically similar and all share the basic melanistic pigment pattern described
here. Although the three species reared in this study can be distinguished on the basis of xanthic pigmentation, it
seems unlikely that it will be possible to reliably identify field-collected larvae to species using traditional morphological and melanistic pigmentation characters. (PDF file contains 36 pages.
Accuracy of Measurement for Counting and Intensity-Correlation Experiments
A quantum-mechanical analysis is made of the experimental accuracy to be expected for particle-counting and intensity-correlation experiments. The mean-square fluctuation for an ensemble, consisting of a large number of experiments each conducted over a time interval T, is calculated
Fluctuations and Relationships of Selected Physiochemical Parameters in Dardanelle Reservoir, Arkansas, 1975-1982
Annual and seasonal fluctuations and relationships are described for discharge, turbidity, chloride, total hardness, conductivity and suspended solids over an eight-year period in Dardanelle Reservoir. The parameters fluctuated rather widely primarily in response to seasonal patterns of rainfall. Chloride and conductivity were related and generally fluctuated together as did turbidity and suspended solids. Hardness appeared to vary independently of the others prior to 1979 then varied more closely with chloride after March 1979. Inherent differences between the Illinois Bayou arm and the main Arkansas River sections complicated the precise identification of any overall impact of power plant operation. No significant long term changes were seen, but chloride declined gradually whereas hardness and conductivity increased slightly. Suspended solids exhibited a significant rise in 1982
A Primary Ecological Survey of Dardanelle Reservoir Prior to Nuclear Facility Effluent Discharge
A preliminary ecological survey of Dardanelle Reservoir during the construction phase of Arkansas Power and Light Company\u27s nuclear generating facility was conducted from January 1970 through June 1974. The reservoir is characterized by relatively shallow depths and a high flow-thru rate. A number of features were associated with these characteristics. The reservoir carried a great deal of suspended material and exhibited high turbidities throughout most of the year. Typical thermal stratification and oxygen depletion were only rarely observed. Many of the physico-chemical parameters exhibited relatively high values in comparison to other Arkansas lakes and reservoirs, but due to absence of prolonged periods of stratification and stagnation, they did not undergo the extreme fluctuations sometimes observed in other reservoirs. Plankton and benthic samples were collected at least nine times per year from ten stations. These stations were selected to include both shallow and deep locations and to include points both within and outside the projected area of thermal influence when the plant became operational. There were a great variety of forms in the phytoplankton with the diatoms making up a considerable portion. The level of turbidity appeared to dampen somewhat the extreme fluctuations sometimes found in bloom periods. In the zooplankton the rotifers Brachionus, Keratella, and Polyarthra predominated followed by the microcrustaceans Cyclops and Bosmina. Both the plankton and the benthic fauna showed great seasonal variation. The benthic fauna consisted primarily of Chironomidae, Oligochaeta, and Hexagenia with the Chironomidae predominating in the shallower depths and the Oligochaeta exhibiting increased abundance and importance in the deeper stations
Physiotherapists’ perceptions of problematic musculoskeletal soft tissue disorders
Original article can be found at: http://www.ijtr.co.uk/ Copyright MA Healthcare Limited.Aims: Many common musculoskeletal disorders are resistant to existing management strategies,causing long-term pain and disability. While arthritic and spinal problems have been prioritized for research, several soft tissue disorders may be equally burdensome for individuals and difficult to treat successfully. dentifying those that are least responsive to reatment may help focus the limited resources available for research and treatment provision. This study aimed to rank the most problematic disorders, and identify contributory factors, to inform the debate on research and service priorities in the management of musculoskeletal disorders. Methods: The views of practising physiotherapists on the most problematic soft tissue disorders were sought using a postal questionnaire survey and telephone interviews. The questionnaire was sent to 193 experienced musculoskeletal physiotherapists working in National Health Service and private clinics in south-east England. Findings: The response rate was 48%. The top three problematic disorders were identifi ed as frozen shoulder, plantar fasciitis and tennis elbow. Subsequent interviews with 20 respondents indicated that inadequate differential diagnosis, triaging and differences in therapeutic practice may account for some of the observed variation in outcomes. Conclusions: A greater focus on these particular disorders and issues by both clinicians and the research community is warranted.Peer reviewe
From individualism to co-construction and back again:Rethinking research methodology for children with profound and multiple learning disabilities
Children with profound and multiple learning disabilities (PMLD) are said to experience severe congenital impairments to consciousness and cognition stemming from neurological damage. Such children are understood as operating at the pre-verbal stages of development, and research in the field typically draws conceptual resources from psychology to devise educational interventions and assessment tools. Criticism has been levelled at studies that treat children with PMLD as objects of research rather than subjects to be consulted. Proponents of the latter view have attempted to redress the situation by exploring how personal experiences can be gleaned through adapted qualitative methods. Debate about methodology in the PMLD field tends to coalesce around these individualist polemics: either children with PMLD are positioned as incompetent and lacking voice; or researchers are positioned as lacking the appropriate tools to gain access to such voice. This paper offers an alternative position to the individualism of post-positivist/constructivist approaches, identifying the need for a critical and participatory approach that sees knowledge about children with PMLD as situated and co-constructed through regular and longitudinal interaction between the researcher, children with PMLD, and significant others. Context to this argument is provided by exploring the application of this approach to an inclusive education research project for a child with PMLD

Phytoplankton Community Structure in Dardanelle Reservoir, Arkansas, 1975-1982
Phytoplankton data were collected with standard equipment and procedures over an eight-year period (1975-1982) in Dardanelle Reservoir, Arkansas. Community abundance and diversity at the genus level are described. Sixty-five genera representing 35 families and five divisions were identified. Total phytoplankton abundance and diversity were quite uniform among the stations but fluctuated considerably with time. These fluctuations did not correspond clearly with season. Dominant taxa were seasonal, though, with diatoms being usually dominant in January, April and October, and blue-greens dominant in July. The phytoplankton community structure has not been significantly altered by the operation of ANO Unit I
