Kinds of Research Council Selected AbstractsSix-month outcomes associated with a brief alcohol intervention for adult in-patients with psychiatric disordersDRUG AND ALCOHOL REVIEW, Issue 2 2002GARY K. HULSE Abstract The objective of this study was to evaluate the 6-month outcomes of a brief intervention to reduce alcohol consumption by psychiatric in-patients in the general hospital setting and following resolution of psychiatric morbidity. Patients from the psychiatric wards of three general hospitals were screened using the Alcohol Use Disorders Identification Test. Of 144 people approached who matched the study criteria, 120 (83%) people aged 18,64 years (mean 31.7) were recruited. Participants were randomized to either a brief motivational interview or an information package to reduce alcohol consumption. Alcohol consumption was assessed as total weekly consumption and categorized on Australian National Health and Medical Research Council (NH&MRC) criteria. We delivered 62 motivational interviews and 58 information packages. At the 6-month follow-up 83 (69%), participants were reassessed. Both groups had significantly reduced alcohol consumption. However, the motivation group had a significantly greater reduction in weekly consumption than the information group (F = 6.8, (1,65) p < 0.025) after controlling for age, sex, SCL-90-R GSI and alcohol dependence (and baseline alcohol consumption). A greater proportion of the motivation group compared to the information group also ,improved' in their classification on NH&MRC criteria (,2 = 7.3, df 1, p < 0.01). Brief interventions, especially motivational interviews, are effective in reducing alcohol use in persons with psychiatric disorders. They are effective across the mid-range of GSI severity scores for in-patients. Screening and brief interventions can and should be incorporated into the routine assessment and management in psychiatric units. [source] The validity of an Australian modification of the AUDIT questionnaireDRUG AND ALCOHOL REVIEW, Issue 2 2001LOUISA J. DEGENHARDT Abstract The Alcohol Use Disorders Identification Test (AUDIT) has been used widely and is reported to be superior to conventional questionnaires in detection of current hazardous and harmful alcohol use. We assessed the validity of an Australian modification of the AUDIT (the AusAUDIT), which has been employed widely in Australian and New Zealand early intervention programmes. We used a cross-sectional study of 370 subjects from the follow-up phase of a randomized controlled trial of early intervention to reduce hazardous alcohol consumption. Scores on the AusAUDIT were compared against 12-month ICD-10 diagnoses of harmful alcohol use and dependence, as determined by the Composite International Diagnostic Interview, and against self-report of alcohol consumption exceeding Australian National Health and Medical Research Council (NH&MRC) recommended limits. AusAUDIT had good internal consistency and discriminated significantly between persons meeting criteria for ICD-10 alcohol use disorders, and drinkers who did not. At currently recommended cut-off scores, AusAUDIT detected more than 85% of people meeting criteria for ICD-10 alcohol use disorders, or drinking over NH&MRC recommended limits, but its specificity was limited (29% in men, and 58% in women for drinking over NH&MRC limits). No subset of questions performed as well as the full AusAUDIT in detection of drinking problems, but the alcohol consumption items provided a reasonable screen for drinking over NH&MRC limits. We conclude that AusAUDIT is effective in detecting problematic drinking, but positive cases should be confirmed by clinical assessment. The findings illustrate the need for validation of questionnaire modifications, and the difficulty in increasing test sensitivity without reducing specificity. [source] Testing Students with Special Needs: A Model for Understanding the Interaction Between Assessment and Student Characteristics in a Universally Designed EnvironmentEDUCATIONAL MEASUREMENT: ISSUES AND PRACTICE, Issue 3 2008Leanne R. Ketterlin-Geller This article presents a model of assessment development integrating student characteristics with the conceptualization, design, and implementation of standardized achievement tests. The model extends the assessment triangle proposed by the National Research Council (Pellegrino, Chudowsky, & Glaser, 2001) to consider the needs of students with disabilities and English learners on two dimensions: cognitive interaction and observation interaction. Specific steps in the test development cycle for including students with special needs are proposed following the guidelines provided byDowning (2006). Because this model of test development considers the range of student needs before test development commences, student characteristics are supported by applying the principles of universal design and appropriately aligning accommodations to address student needs. Specific guidelines for test development are presented. [source] Conceptualizing Teaching as Science: John Dewey in Dialogue with the National Research CouncilEDUCATIONAL THEORY, Issue 1 2004Greg Seals John Dewey and the National Research Council (NRC) both discuss the problem of translating scientific research into contexts of schooling, but differ about the proper solution to the problem. The NRC would solve it by empirical investigation. Dewey finds value in that approach, but also wants educational theorists to construct general heuristics to guide scientists in creating research agendas of intrinsic interest to education practitioners. Dewey's plan faces an apparently insurmountable difficulty. General heuristics of the sort Dewey needs are not widely recognized to exist. In light of the presumed fact of education's inability to articulate a general framework to guide teaching practice, the NRC plan becomes preferred by default. I propose that Experience and Education provides a frame of reference from which pedagogical practice appears as a field of scientific endeavor in its own right. Conceptualizing teaching as a science suggests ways to rework the NRC plan. [source] Options in Prehospital analgesiaEMERGENCY MEDICINE AUSTRALASIA, Issue 1 2002Meredith L Borland Abstract Background: Prehospital analgesia options for paramedics have been limited due to the difficulty in achieving safe and effective pain relief without compromising transportation to hospital. The present paper identifies the analgesia methods currently available in the prehospital setting so as to evaluate the various options and highlight areas for future research. Methods: A literature review of Medline and Embase databases from 1966 until the present was undertaken. Further hand searching of all the references identified in these papers was also performed. All current literature was analysed and categorized according to one of four levels of evidence using National Health and Medical Research Council of Australia guidelines (1999). Results: There is a paucity of randomized control trials relating to prehospital analgesia. All published literature was level III or IV prospective or retrospective studies. Drug options used included nitrous oxide/oxygen mixtures, intravenous/intramuscular nalbuphine, intravenous tramadol and intravenous pure opiate agonists. Conclusions: The evidence supporting analgesic options in the prehospital setting is limited. There are few published data in this area despite the inadequacy of pain relief being recognized as a weakness in prehospital care. Prehospital analgesia is an area worthy of innovative methods for the administration of safe and effective analgesics without significant impact on transport times. Such methods should be prospectively evaluated in well-constructed trials. [source] Thermal properties of lightweight-framed construction components at elevated temperaturesFIRE AND MATERIALS, Issue 3 2005Noureddine Bénichou Abstract Fire resistance behaviour of lightweight-framed assemblies is determined by defining the thermal and structural performances of the assembly when exposed to fire. To adequately model thermal behaviour in a lightweight wood-framed assembly, thermal properties of the components of the assembly at elevated temperatures must be well defined. This paper presents results of measurements of thermal properties at elevated temperatures of construction materials commonly used to build lightweight wood-framed assemblies that were conducted at the National Research Council of Canada since 1990. The test results, in graphical form, are given as a function of temperature for thermal conductivity, specific heat, mass loss and thermal expansion/contraction for wood, gypsum and insulation. In addition, the effects of temperature on the thermal conductivity, specific heat, mass loss and thermal expansion/contraction of these materials are discussed. Finally, in addition to providing a resource of information, this paper also identifies the additional thermal property tests required to complete the matrix of information.

[source] Innovative Governance and Development in the New Ireland: Social Partnership and the Integrated ApproachGOVERNANCE, Issue 1 2004J. D. House Since the mid-1980s, the economy of the Republic of Ireland has displayed a remarkable turnaround. Its Gross Domestic Product (GDP) has grown at a faster rate than any developed country in the world. The government's deficit has been cut severely and the debt-to-GDP ration sharply reduced. Average incomes have risen significantly, and the unemployment rate reduced dramatically. This article documents these changes. Its main purpose, however, is to provide a plausible explanation for the "Irish miracle." While many factors have been important,support for the Economic Union's regional development programs, a favorable tax structure, locational and language advantages for attracting multinational corporations, strong education and training programs,these factors in themselves do not explain the emergence of the "Celtic tiger." They were in place before the mid-1980s when Ireland was suffering from a fiscal, economic, and political crisis. Instead, the article argues, it was the creative and innovative response of Irish leaders in government, industry, and labor movement and community organizations to the crisis, and the subsequent institutionalization of this response in a new form of governance, that has been the catalyst for the Irish success story. Based on the thorough background research of the Economic and Social Research Council, a farsighted group of leaders developed a strategic plan in 1987 that provided a blueprint for constructive economic and social change. This was then formally instituted for wage restraint on the part of labor in return for income tax and social supposed provisions by government. Irish social Partnership is modeled to some extent on Northern European corporatism. The article reviews corporatism as an early form of innovative governance, using classical corporatism in Sweden and competitive corporatism in the Netherlands to illustrate how this approach has evolved over the years. Dutch economic success in recent years is due in part to its new form of corporatism that has helped it become globally competitive. It is argued, however, that Irish social partnership goes beyond continental corporatism in several important ways. It is more inclusive, covering a large array of social interests; it is more strategic, with a well-articulated integrated approach to social and economic development that is self-corrective and articulated in a new national agreement every three years; and it is more firmly institutionalized in both government and nongovernment agencies in the country. Social partnership and the integrated approach have become part of the culture of the new Ireland. This innovative form of governance underlies the Irish turnaround and augurs well for the future. It can also serve as a model, with appropriate modification tailor-made to each case, for other jurisdictions hoping to emulate Ireland's success. [source] Use of fresh-frozen plasma at Royal Darwin Hospital: a retrospective auditINTERNAL MEDICINE JOURNAL, Issue 9 2008S. Moylan Abstract Background:, The aim of the study was to assess the appropriateness of use of fresh-frozen plasma (FFP) at Royal Darwin Hospital against the National Health and Medical Research Council and Australian and New Zealand Society for Blood Transfusion guidelines. Methods:, A retrospective review of blood product request forms, online pathology storage system data, pathology records and clinical notes between 1 January 2006 and 31 December 2006 was carried out. The appropriateness of requests was assessed against existing guidelines. The percentage of appropriate and inappropriate FFP transfusions was obtained. Results:, Six hundred and forty-eight of 950 units (68%) of FFP were used with an appropriate indication as per National Health and Medical Research Council/Australian and New Zealand Society for Blood Transfusion guidelines. Of the remaining units, 14% (137 units) was given without a clear indication and a decision of appropriateness could not be established for 17% (165 units) because of inadequate clinical or pathology information (e.g. coagulation results). Multiple issues around prescribing practice were identified. Conclusion:, There is significant use of FFP at Royal Darwin Hospital without clear clinical indication. The employment of a transfusion nurse to monitor use of FFP (and other blood products) and provide education is aimed at improving transfusion efficiency and patient safety. [source] Experimental modelling and intelligent control of a wood-drying kilnINTERNATIONAL JOURNAL OF ADAPTIVE CONTROL AND SIGNAL PROCESSING, Issue 8 2001Givon Chuen Kee Yan Abstract Proper control of the wood-drying kiln is crucial in ensuring satisfactory quality of dried wood and in minimizing drying time. This paper presents the development, implementation, and evaluation of a control system for a lumber drying kiln process incorporating sensory feedback from in-wood moisture content sensors and intelligent control such that the moisture content of lumber will reach and stabilize at the desired set point without operator interference. The drying process is difficult to model and control due to complex dynamic nonlinearities, coupling effects among key variables, and process disturbances caused by the variation of lumber sizes, species, and environmental factors. Through system identification scheme using experimental data and recursive least-squares algorithm for parameter estimation, appropriate models are developed for simulation purpose and controller design. Two different control methodologies are employed and compared: a conventional proportional-integral-derivative (PID) controller and a direct fuzzy logic controller (FLC), and system performance is evaluated through simulations. The developed control system is then implemented in a downscaled industrial kiln located at the Innovation Centre of National Research Council (NRC) of Canada. This experimental set-up is equipped with a variety of sensors, including thermocouples for temperature feedback, an air velocity transmitter for measuring airflow speed in the plenum, relative humidity sensors for measuring the relative humidity inside the kiln, and in-wood moisture content sensors for measuring the moisture content of the wood pieces. For comparison, extensive experimental studies are carried out on-line using the two controllers, and the results are evaluated to tune the controller parameters to achieve good performance in the wood-drying kiln. The combination of conventional control with the intelligent control promises improved performance. The control system developed in this study may be applied in industrial wood-drying kilns, with a clear potential for improved quality and increased speed of drying.

Kortenkamp Summary There is widespread exposure to anti-androgens, a group of chemicals able to disrupt androgen action in foetal life, with irreversible de-masculinizing consequences. Substances of concern include certain phthalates, pesticides and chemicals used in cosmetics and personal care products. Although people come into contact with several anti-androgens, chemicals risk assessment normally does not take account of the effects of combined exposures. However, a disregard for combination effects may lead to underestimations of risks and for this reason, we have assessed the feasibility of conducting cumulative risk assessment, where the focus is on considering the effects of exposure to multiple chemicals, via multiple routes and pathways. Following recent recommendations by the US National Research Council, we have, for the first time, included phthalates and other anti-androgenic chemicals, a total of 15 substances. On the basis of exposure estimates for the individual chemicals and reference doses for anti-androgenicity, we have used the hazard index approach. We show that the cumulative risks from anti-androgen exposures exceed acceptable levels for people on the upper end of exposure levels. The value obtained for median exposures to the 15 substances can be judged tolerable. However, significant knowledge gaps exist that prevent us from arriving at definitive conclusions. Of greatest concern is an absence of appropriate in vivo toxicity data about large numbers of in vitro androgen receptor antagonists. Knowledge about the effect profiles of these chemicals will lead to higher risk estimates. Our analysis suggests that risk reductions can be achieved by limiting exposures to the plasticizer diethyl hexyl phthalate, the cosmetic ingredients butyl- and propyl paraben, the pesticides vinclozolin, prochloraz and procymidone and bisphenol A. [source] Impact of COPD severity on physical disability and daily living activities: EDIP-EPOC I and EDIP-EPOC II studiesINTERNATIONAL JOURNAL OF CLINICAL PRACTICE, Issue 5 2009J. M. Rodriguez Gonzalez-Moro Summary Aims:, The severity of chronic obstructive pulmonary disease (COPD) is associated to patients' health-related quality of life (HRQL). Physical impairment increasingly affects daily activities creating economic, social and personal burden for patients and their families. This burden should be considered in the management of COPD patients; therefore, we intended to assess the impact of the disease severity on physical disability and daily activities. Methods:, Two epidemiological observational cross-sectional descriptive studies were carried out in 1596 patients with moderate COPD and 2012 patients with severe or very severe COPD in the routine clinical practice. Demographic and basic clinical-epidemiological data were collected and patients completed questionnaires to assess their physical disability because of COPD [Medical Research Council (MRC)], COPD repercussion on daily activities [London Chest Activity of Daily Living (LCADL)], job, economy and family habits and their health status [EQ-5D visual analogue scale (VAS)]. Results:, In all, 37% of severe/very severe COPD patients and 10% of moderate (p < 0.0001) had MRC grades 4 and 5. Mean global LCADL was significantly higher in severe/very severe than in moderate patients [29.6 (CI 95%: 28.91,30.25) vs. 21.4 (CI 95%: 20.8,21.9); p < 0.0001]. COPD job impact and economic and family habits repercussions were significantly higher and health status significantly worse in severe/very severe cases than in patients with moderate COPD. Conclusions:, COPD severity is highly associated with physical disability by MRC grading, with functionality on daily activities and with impairment of other social and clinical activities. Moderate COPD patients show already a significant degree of impairment in all these parameters. [source] Enhancement of the conjugated linoleic acid and vitamin A and E contents in goat milk through green fodder feedingINTERNATIONAL JOURNAL OF DAIRY TECHNOLOGY, Issue 1 2009AMRISH TYAGI Twelve lactating crossbred goats (Sanan × Beetal) in early lactation were divided into two groups of six each. Group I was fed on fresh berseem fodder (Trifolium alexandrinum), whereas group II was fed on berseem fodder and concentrate mixture in 1 : 1 ratio to fulfil their nutritional requirements as per National Research Council (1981). Feed intake and milk yield were recorded daily, and milk samples were collected on 0, 30, 45 and 60 days of experimental feeding for the estimation of fat, vaccenic acid, conjugated linoleic acid (CLA), vitamins A and E, and total antioxidant activity. There was no effect (P > 0.05) of dietary treatments on daily as well as total milk yield and milk fat, solids-not-fat and total solids, although average total CLA (mg/g fat) content in milk during the trial was higher(P < 0.01) in group I (18.92) in comparison to group II (10.94). Vitamin A content averaged 0.46 and 0.27 µg/mL and vitamin E, 1.20 and 1.38 µg/mL in milk of groups I and II, respectively, were higher in the berseem-fed group (P < 0.01) and total antioxidant activity of milk was also higher (P < 0.01) in group I than in group II. [source] Dermatomyositis presenting as panniculitisINTERNATIONAL JOURNAL OF DERMATOLOGY, Issue 2 2000Yen-Yu Chao MD A 44-year-old obese woman was transferred to our clinic with a diagnosis of panniculitis. Examination showed multiple, indurated, erythematous, painful nodules and plaques distributed on the shoulders, back, forechest, abdomen, buttock, and bilateral thighs. These skin lesions appeared 2 months previously, measured 5,8 cm, and were tender on palpation. No obvious inducing factor was traced. The lesions seemed unresponsive to treatment with nonsteroidal anti-inflammatory drugs (ibuprofen, 400 mg three times a day) as similar lesions appeared in subsequent visits. Progressive proximal muscle weakness was found 1 month later. She was then admitted via the emergency room because of extensive painful skin plaques and abdominal pain. Diffuse erythematous to violaceous swelling of the face, neck, and shoulder was noted at about the same time ( Fig. 1). A skin biopsy specimen from the nodular lesion showed poikilomatous epidermal changes ( Fig. 2), and marked mononuclear cell infiltration in the dermis and subcutaneous fat ( Fig. 3). Dermatomyositis was considered as the diffuse violaceous facial erythema could be a form of heliotrope eruption, but Gottron's papule was not found. At admission, serum creatinine phosphokinase (CPK) was mildly elevated (436 IU/L; normal range, 20,170 IU/L), but serum asparagine transaminase (AST) and lactate dehydrogenase (LDH) levels were within normal limits (36 IU/L; normal, 11,47 IU/L; and 108 IU/L; normal, 90,280 IU/L, respectively). Antinuclear antibody was 1 : 80 positive with an atypical speckled pattern. Muscle strength was weakest during the first 2 days, about grade 3 by the Medical Research Council (MRC) of Great Britain scale. Gower's sign was positive. An electromyogram showed myopathic changes and a nerve conduction velocity study was normal. Serum enzymes were elevated further on the third day: AST, 55 IU/L; CPK, 783 IU/L with 100% MM form. The diagnosis of dermatomyositis was established. As for the work-up result, anti-dsDNA antibody, anti-ENA antibody, and anti-Jo1 antibody were negative. Tumor marker screen (,-HCG, AFP, CEA, and CA-125), was negative, and rhinolaryngopharyngoscope examination and gynecologic sonography were normal. Figure 1. Diffuse erythematous swelling with subtle violaceous hue extending from the temporal area to the cheeks, neck, and shoulders. The crusted lip ulcers of herpes simplex were also noted Figure 2. Basketweave hyperkeratosis, mild acanthosis, subtle vacuolar degeneration of the basal cells, and melanin incontinence (hematoxylin and eosin, ×400) Figure 3. Heavy mononuclear cells infiltrated in the subcutaneous fat tissue (hematoxylin and eosin, ×100) Pancreatitis was initially suspected because of epigastric pain and tenderness, elevated serum lipase (382 U/L; normal, 23,200 U/L), and amylase (145 U/L; normal, 35,118 U/L). No evidence of pancreatitis could be found in abdominal sonography and abdominal computed tomography (CT), however. The epigastric pain and tenderness subsided soon after admission and the serum pancreatic enzyme level declined on the second day (amylase 69 U/L; lipase, 276 U/L). The patient was then diagnosed with dermatomyositis and treated with prednisolone (120 mg/day). CPK dropped dramatically from 3286 IU/L the day before treatment to 1197 IU/L 3 days after. Panniculitis lessened and the muscle power improved after 1 week of treatment. The disease activity fluctuated even with treatment with prednisolone and the patient often felt listless and weak. The muscle weakness sometimes deteriorated to affect the patient's mobility. Facial erythema and panniculitis-like lesions were found during the worse times. Methotrexate and azathioprine were then added (7.5 mg and 250 mg per week, respectively), but CPK was still mildly elevated (189 IU/L), and the patient still felt ill. Human immune globulin (5%, 500 mL per day, 5 days per month) intravenous infusion was initiated thereafter. There was a dramatic response. Full muscle strength was retained and CPK was within the normal range in the following 6 months with only immune globulin therapy. [source] Comprehensive measurement of maternal satisfaction: The modified Mason SurveyINTERNATIONAL JOURNAL OF NURSING PRACTICE, Issue 3 2002Maree Johnson RN A three-stage process was undertaken to identify and modify a tool that was capable of measuring the many aspects of maternal satisfaction relevant to Australian women. First, the scope of maternal satisfaction to be measured was defined by summarizing available literature and surveys purporting to measure maternal satisfaction (including surveys used in maternity services in New South Wales). The multidimensional nature of maternal satisfaction was confirmed, with 16 core aspects (common to the literature and local surveys) and nine additional unique aspects of maternal satisfaction being identified. Second, these core and additional aspects were used to examine the comprehensiveness of the Mason Survey, a survey recommended by the National Health and Medical Research Council of Australia for use in maternity services. Eighty-eight per cent of the core and additional aspects (22/25) were found to be present in the Mason Survey. Third, an expert panel further modified the Mason Survey by removing items not applicable to the Australian context. The modified Mason Survey is a comprehensive measure of maternal satisfaction suitable for Australian women and capable of providing valuable information on the quality of services and future planning for maternity services.

[source] Pain assessment in older people with dementia: literature reviewJOURNAL OF ADVANCED NURSING, Issue 1 2009Linda McAuliffe Abstract Title.,Pain assessment in older people with dementia: literature review. Aim., This paper is a report of a literature review conducted to identify barriers to successful pain assessment in older adults with dementia and possible strategies to overcome such barriers. Background., Pain is frequently undetected, misinterpreted, or inaccurately assessed in older adults with cognitive impairment. These people are often unable to articulate or convey how they feel and are often perceived as incapable of experiencing or recalling pain. Data sources., Searches were conducted of CINAHL, Medline and other databases for the period 1993,2007 using the search terms pain, dementia, assess*, barrier* and obstacle*. Methods., Studies were critically appraised by two independent reviewers. Data were extracted using instruments specifically developed for the review. Studies were categorized according to levels of evidence defined by the Australian National Health and Medical Research Council and Joanna Briggs Institute. Results., Perceived barriers to successful pain assessment in people with dementia included lack of recognition of pain, lack of sufficient education and/or training, misdiagnosis or late diagnosis, and non-use of assessment tools. Barriers related to people with dementia included insufficient evidence, the possibility of a ,no pain' subset of people with dementia, type of pain, and stoical attitudes. Strategies proposed as means of overcoming these barriers included knowing the person, knowing by diversity/intuitive perception, education and training, and use of adequate tools. Conclusion., More extensive education and training about the relationship between pain and dementia are urgently needed, as is the development and implementation of an effective pain assessment tool specifically designed to detect and measure pain in older adults with all stages of dementia. [source] The ecological research needs of businessJOURNAL OF APPLIED ECOLOGY, Issue 2 2010Paul R. Armsworth Summary 1.,Businesses have an unrivalled ability to mobilize human, physical and financial capital, often manage large land holdings, and draw on resources and supply products that impact a wide array of ecosystems. Businesses therefore have the potential to make a substantial contribution to arresting declines in biodiversity and ecosystem services. To realize this potential, businesses require support from researchers in applied ecology to inform how they measure and manage their impacts on, and opportunities presented to them by, biodiversity and ecosystem services. 2.,We reviewed papers in leading applied ecology journals to assess the research contribution from existing collaborations involving businesses. We reviewed applications to, and grants funded by, the UK's Natural Environment Research Council for evidence of public investment in such collaborations. To scope opportunities for expanding collaborations with businesses, we conducted workshops with three sectors (mining and quarrying, insurance and manufacturing) in which participants identified exemplar ecological research questions of interest to their sector. 3.,Ten to fifteen per cent of primary research papers in Journal of Applied Ecology and Ecological Applications evidenced business involvement, mostly focusing on traditional rural industries (farming, fisheries and forestry). The review of UK research council funding found that 35% of applications mentioned business engagement, while only 1% of awarded grants met stricter criteria of direct business involvement. 4.,Some questions identified in the workshops aim to reduce costs from businesses' impacts on the environment and others to allow businesses to exploit new opportunities. Some questions are designed to inform long-term planning undertaken by businesses, but others would have more immediate commercial applications. Finally, some research questions are designed to streamline and make more effective those environmental policies that affect businesses. 5.,Business participants were forward-looking regarding ecological questions and research. For example, representatives from mining and quarrying companies emphasized the need to move beyond biodiversity to consider how ecosystems function, while those from the insurance sector stressed the importance of ecology researchers entering into new types of interdisciplinary collaboration. 6.,Synthesis and applications. Businesses from a variety of sectors demonstrated a clear interest in managing their impacts on, and exploiting opportunities created by, ecosystem services and biodiversity. To achieve this, businesses are asking diverse ecological research questions, but publications in leading applied ecology journals and research council funding reveal limited evidence of direct engagement with businesses. This represents a missed opportunity for ecological research findings to see more widespread application. [source] Large-scale ecology and hydrology: an introductory perspective from the editors of the Journal of Applied EcologyJOURNAL OF APPLIED ECOLOGY, Issue 2000S.J. Ormerod 1. Five key features characterize large-scale factors in ecology: (a) they incorporate some of the most major of all ecological phenomena , the ranges of organisms, patterns of diversity, variations in ecosystem character and environmental processes such as climate, biogeochemical cycles, dispersal and migration; (b) they involve interactions across scales through both top-down and bottom-up processes; (c) they are multifaceted, and hence require an interdisciplinary perspective; (d) they reflect the cumulative effects of anthropogenic change across all scales, and so have direct relevance to environmental management; (e) they invariably exceed the range of classical ecological experiments, and so require alternative approaches to hypothesis testing. 2. Against this background, a recent research initiative on large-scale ecology and hydrology was funded jointly by the Natural Environment Research Council (NERC) and the Scottish Executive Rural Affairs Department (SERAD). Outputs from this programme are reported in this special issue of the Journal of Applied Ecology, and they illustrate some of the ecological research that is currently in progress in the UK at large spatio-temporal scales. 3. The spatial scales investigated in the papers range from hectares to whole continents, and much of the work reported here involves modelling. Although the model outputs are intrinsically valuable, several authors express the need for improved validation and testing. We suggest that this is an area requiring much development, and will need considerable innovation due to the difficulties at the scales involved (see 1d). Possible methods include: model applications to new circumstances; large-scale environmental manipulations; large-scale surveys that mimic experimental protocols; support from process studies at smaller scales. These alternatives are not mutually exclusive, and all can allow robust hypothesis testing. 4. Much of the work reported here is interdisciplinary linking, for example, geographical, mathematical, hydrological, hydrochemical and ecological concepts (see 1c). We suggest that even stronger links between environmental disciplines will further aid large-scale ecological research. 5. Most important in the context of the Journal of Applied Ecology, the work reported in this issue reveals that large-scale ecology already has applied value. Sectors benefiting include the conservation of biodiversity, the control of invasive species, and the management of land and water resources. 6. Large-scale issues continue to affect many applied ecologists, with roughly 30,40% of papers published in the Journal of Applied Ecology typically confronting such problems. This special issue adds to the growing body of seminal contributions that will add impetus to further large-scale work. Moreover, occurring in a period when other areas of biology are increasingly reductionist, this collection illustrates that, at least with respect to large-scale environmental problems, ecology still holds centre ground. [source] Large-scale processes in ecology and hydrologyJOURNAL OF APPLIED ECOLOGY, Issue 2000R.W.G. Caldow 1. Several papers published in the 1980s stressed the importance of scaling issues, the inter-relatedness of patterns and processes at different scales of time and space, to our understanding of ecological systems. Scaling issues are of major theoretical interest and increasingly are of considerable applied importance. 2. In recognition of this, the Natural Environment Research Council, in partnership with the Scottish Executive Rural Affairs Department, funded a Thematic Programme entitled ,Large-scale Processes in Ecology and Hydrology'. The principal aim of this Programme was to integrate recent major developments in information resources and technologies with current theory in order to improve understanding of large-scale patterns and processes and their relationship to patterns and processes at smaller scales. 3. The Thematic Programme, which ran from 1995 until 1999, funded six research projects that have generated a large body of published papers. This volume, dedicated to the findings of the Programme, brings together outputs from all six projects with the aim of ensuring a rapid and widespread dissemination of the Programme's findings. A brief résumé of each of the papers is presented. 4. The papers in this volume cover a wide variety of subjects ranging from ions to the flora and fauna of the United Kingdom. Nonetheless, each study has sought in various ways to quantify observed spatio-temporal patterns at a range of scales, to determine whether those patterns are consistent across scales and to identify the interactions between small-scale patterns and processes and those at larger scales. The importance of the spatial and temporal scales at which studies are conducted, the key role played by dispersal in spatial population dynamics, and the diversity of ways in which large-scale patterns and processes relate to those at smaller scales are highlighted in many of the papers. 4. All of the papers presented here have direct relevance to applied issues. These issues are diverse and include the control of invasive alien species, the conservation of declining, threatened or endangered species, the development of survey techniques, strategies for farmland, woodland and forestry management, and the assessment of pollution sensitivity. Thus, the Thematic Programme has addressed issues of considerable theoretical interest and has at the same time generated results and predictive models that are of considerable practical and policy relevance. [source] Good work , how is it recognised by the nurse?JOURNAL OF CLINICAL NURSING, Issue 12 2008Bjørg Christiansen Dr. Polit. Aim., The aim of this paper is to shed light on how nurses describe situations that reflect achievement and provide confirmation that they have done good work. Background., Nurses' recognition of good work does not seem to have been the object of direct investigation, but is indirectly reflected in studies focusing on nurses' perceptions on work environments and the multifaceted nature of nursing. However, acknowledging high-quality performance in professional nurses can facilitate nurses in maintaining and strengthening the goals and values of the profession. This in turn can help nurses shoulder the multifaceted responsibilities they have to patients and next of kin. Design., This paper is part of the Professional Learning in a Changing Society project, Institute of Educational Research, University of Oslo, funded by the Research Council of Norway. The project involves four professional groups. This paper, however, focuses on a group of 10 nurses, nine of whom work in hospitals and one in an outpatient clinic. A qualitative approach was chosen to gain insight into how nurses, as well as the other professional groups in the project, engage in processes of knowledge production and quality assurance work. Methods., Data presented in this paper derive from semi-structured in-depth interviews conducted during spring 2005 and focuses on the recognition of good work. Results., The following themes were identified as essential in confirming that one did good work: securing fundamental needs of patients and next of kin; managing the flow of responsibilities; positive feedback. Conclusions., Good work seems to be related to specific situations and a sense of achievement by the respondents. Relevance to clinical practice., Recognition of good work is not only rewarding and enjoyable; it may also serve as a source of consciousness raising for professional and ethical guidelines in the work place. [source] Consistency of Angoff-Based Predictions of Item Performance: Evidence of Technical Quality of Results From the Angoff Standard Setting MethodJOURNAL OF EDUCATIONAL MEASUREMENT, Issue 4 2000Barbara S. Plake Judgmental standard-setting methods, such as the Angoff(1971) method, use item performance estimates as the basis for determining the minimum passing score (MPS). Therefore, the accuracy, of these item peformance estimates is crucial to the validity of the resulting MPS. Recent researchers (Shepard, 1995; Impara & Plake, 1998; National Research Council. 1999) have called into question the ability of judges to make accurate item performance estimates for target subgroups of candidates, such as minimally competent candidates. The propose of this study was to examine the intra- and inter-rater consistency of item performance estimates from an Angoff standard setting. Results provide evidence that item pelformance estimates were consistent within and across panels within and across years. Factors that might have influenced this high degree of reliability, in the item performance estimates in a standard setting study are discussed. [source] A Strategic Story of Using Computer Technology: The EPA Project by HOKJOURNAL OF INTERIOR DESIGN, Issue 1 2000Joan McLain-Kark Ph.D. ABSTRACT Interior design researchers study computer technology in order to understand its impact on design processes and education. Yet, whether the use of the computer has made interior designers better at improving the life of users remains to be seen. The purpose of this research is to examine the use of technology in design through a narrative case, the EPA project by Hellmuth, Obata, and Kassabaum (HOK), to offer insights into how computers can be used to make a design compatible with user needs. Three indivdiuals involved with the EPA project were interviewed and audiotaped regarding the design and computer modeling of the labs. The transcripts were subsequently analyzed for dominant themes. The researcher developed a narrative using a structure established by the FIDER Research Council. The results indicate that repeated involvement of the scientists in the design process through evaluation via the walk-through animation and other means resulted in a positive evaluation. The case provides insights on how computer technology can be optimized to improve the design for end-users. Using the EPA story and present trends in computer technology as a foundation, the article presents a scenario to help designers consider ways for integrating the latest computer modeling technology into their practice. [source] Ice caps existed throughout the Lateglacial Interstadial in northern Scotland,JOURNAL OF QUATERNARY SCIENCE, Issue 5 2008Tom Bradwell Abstract We constrain, in detail, fluctuations of two former ice caps in NW Scotland with multibeam seabed surveys, geomorphological mapping and cosmogenic 10Be isotope analyses. We map a continuous sequence of 40 recessional moraines stretching from ,10,km offshore to the Wester Ross mountains. Surface-exposure ages from boulders on moraine ridges in Assynt and the Summer Isles region show that substantial, dynamic, ice caps existed in NW Scotland between 13 and 14,ka BP. We interpret this as strong evidence that large active glaciers probably survived throughout the Lateglacial Interstadial, and that during the Older Dryas period (ca. 14,ka BP) ice caps in NW Scotland were thicker and considerably more extensive than in the subsequent Younger Dryas Stadial. By inference, we suggest that Lateglacial ice-cap oscillations in Scotland reflect the complex interplay between changing temperature and precipitation regimes during this climatically unstable period (ca. 15,11,ka BP). © Natural Environment Research Council (NERC) copyright 2008.

[source] Combined oxygen and silicon isotope analysis of biogenic silica,JOURNAL OF QUATERNARY SCIENCE, Issue 4 2008Melanie J. Leng Abstract There is increasing interest in the use of biogenic silica O and Si isotope ratios to understand climate and environmental processes. Virtually all of the fairly substantial body of literature deals with either oxygen or silicon. This is partly because measurement of oxygen isotope composition is done using either vacuum dehydration, isotope exchange or stepped fluorination techniques, while increasingly researchers are turning to multicollector inductively coupled plasma mass spectrometry (MC-ICP-MS) for Si isotope analysis, even though Si isotope analysis can be done using fluorination methods used for the oxygen isotope measurements. Here we describe a procedure for simultaneous determination of isotopic abundances of oxygen and silicon from the same aliquot of biogenic silica. Pure silica is dissociated into O and Si compounds using a fluorination technique, in which reaction with bromine pentafluoride (BrF5) produces oxygen (O2, subsequently converted to CO2), silicon tetrafluoride (SiF4) and other fluorine by-products (e.g. BrF3). These compounds are cryogenically separated using cold traps. Yields for oxygen and silicon recovery are 70,80% for biogenic silica depending on the nature of the hydrous layer and 97,99% for pure quartz. Reproducibility of the oxygen isotopic composition is ca. 0.3, and silicon between 0.06,0.12,. © Natural Environment Research Council (NERC) copyright 2008. Reproduced with the permission of NERC.

[source] Building a learning progression for celestial motion: Elementary levels from an earth-based perspectiveJOURNAL OF RESEARCH IN SCIENCE TEACHING, Issue 7 2010Julia D. Plummer Abstract Prior research has demonstrated that neither children nor adults hold a scientific understanding of the big ideas of astronomy, as described in standards documents for science education [National Research Council [1996]. National science education standards. Washington, DC: National Academy Press; American Association for the Advancement of Science 1993. Benchmarks for science literacy. New York: Oxford University Press]. This manuscript focuses on ideas in astronomy that are at the foundation of elementary students' understanding of the discipline: the apparent motion of the sun, moon, and stars as seen from an earth-based perspective. Lack of understanding of these concepts may hinder students' progress towards more advanced understanding in the domain. We have analyzed the logic of the domain and synthesized prior research assessing children's knowledge to develop a set of learning trajectories that describe how students' initial ideas about apparent celestial motion as they enter school can be built upon, through successively more sophisticated levels of understanding, to reach a level that aligns with the scientific view. Analysis of an instructional intervention with elementary students in the planetarium was used to test our initial construction of the learning trajectories. This manuscript presents a first look at the use of a learning progression framework in analyzing the structure of astronomy education. We discuss how this work may eventually lead towards the development and empirical testing of a full learning progression on the big idea: how children learn to describe and explain apparent patterns of celestial motion. © 2009 Wiley Periodicals, Inc.

Plummer Abstract The National Science Education Standards [National Research Council (1996) National science education standards. Washington, DC: National Academy Press] recommend that students understand the apparent patterns of motion of the sun, moon and stars by the end of early elementary school. However, little information exists on students' ability to learn these concepts. This study examines the change in students' understanding of apparent celestial motion after attending a planetarium program using kinesthetic learning techniques. Pre- and post-interviews were conducted with participants from seven classes of first and second grade students (N,=,63). Students showed significant improvement in knowledge of all areas of apparent celestial motion covered by the planetarium program. This suggests that students in early elementary school are capable of learning the accurate description of apparent celestial motion. The results also demonstrate the value of both kinesthetic learning techniques and the rich visual environment of the planetarium for improved understanding of celestial motion. © 2008 Wiley Periodicals, Inc.

This committee provided an early formulation of personality and culture that emphasized the interdisciplinary focus on the processes of personality formation within small-scale social settings. The committee's formulation also coupled personality and culture with a liberal social engineering approach geared toward cultural reconstruction. Major social scientists and clinicians were involved in the activities of the committee, including Edward Sapir, W. I. Thomas, E. W. Burgess, E. A. Bott, Robert S. Woodworth, Harry Stack Sullivan, C. M. Hincks, and Adolf Meyer. © 2009 Wiley Periodicals, Inc. [source] Proposals for 2001 samples of anonymized records: An assessment of disclosure riskJOURNAL OF THE ROYAL STATISTICAL SOCIETY: SERIES A (STATISTICS IN SOCIETY), Issue 3 2001Angela Dale In 1991 Marsh and co-workers made the case for a sample of anonymized records (SAR) from the 1991 census of population. The case was accepted by the Office for National Statistics (then the Office of Population Censuses and Surveys) and a request was made by the Economic and Social Research Council to purchase the SARs. Two files were released for Great Britain,a 2% sample of individuals and a 1% sample of households. Subsequently similar samples were released for Northern Ireland. Since their release, the files have been heavily used for research and there has been no known breach of confidentiality. There is a considerable demand for similar files from the 2001 census, with specific requests for a larger sample size and lower population threshold for the individual SAR. This paper reassesses the analysis of Marsh and co-workers of the risk of identification of an individual or household in a sample of microdata from the 1991 census and also uses alternative ways of assessing risks with the 1991 SARs. The results of both the reassessment and the new analyses are reassuring and allow us to take the 1991 SARs as a base-line against which to assess proposals for changes to the size and structure of samples from the 2001 census.
