Kinds of Assessment Process Selected AbstractsTemporal reliability of psychological assessments for patients in a special hospital with severe personality disorder: a preliminary noteCRIMINAL BEHAVIOUR AND MENTAL HEALTH, Issue 2 2005Professor P. Tyrer Background The new programme for assessing those with dangerous and severe personality disorder relies heavily on psychological assessments of personality disorder and risk. Methods The temporal reliability of assessments of psychopathy (PCL-R), risk (HCR-20) and personality was assessed using the International Personality Disorder Examination (IPDE) in 15 randomly selected male prisoners in a high secure hospital carried out at intervals varying between a mean of nine and 19 months after initial assessments by a variety of assessors. Results Using the intra-class correlation coefficient the agreement varied between0.57 (HCR-20), 0.58 (PCL-R) and 0.38-0.70 for IPDE personality disorders, with the best agreement for antisocial personality disorder (0.70). Comment These levels of agreement are consistent with other recent work on temporal reliability of personality instruments but are a little too low for confidence in these measures alone in the assessment process.

Welsh Many individuals within Laboratory Medicine will be unaware that CPA conducts assessments to two different sets of CPA Standards. There are the Standards for the Medical Laboratory and the Standards for EQA Schemes in Laboratory Medicine. The style and format of both sets of standards is very similar with each being presented in eight sections A , H. The EQA standards are almost identical to the laboratory standards with the exception of the E.F and G standards which are specific to EQA schemes. There are approximately 40 EQA Schemes registered with CPA compared with almost 2 500 laboratories. These EQA schemes vary from very large national/international schemes with numerous analytes to small interpretive schemes run by one individual with a personal interest in that specific subject. The large schemes usually come under the UKNEQAS consortia banner and due to their size and configuration do not present undue problems in the assessment process. Smaller interpretive EQA schemes present a challenge both for the scheme and CPA in gaining accreditation. These schemes are usually within the discipline of Histopathology and are regarded as educational rather than proficiency testing schemes. Very frequently, the scheme is organized by a single individual with a collection of microscope slides, storage facilities for the slides and a computer. This presents the Scheme Organizer with great difficulty in complying with the Quality Management System requirements of the CPA Standards. There are a number of models which can be applied in order to satisfy the requirement of the Quality Management System, but ultimately it must be recognized that in some circumstances it is not possible to accredit these small schemes. The NHSCSP Gynae Cytology EQA Scheme is probably the largest EQA scheme within the UK, in respect of the number of participants and the number of staff supporting the scheme. Scheme Management decided that all nine regions of England would apply for accreditation under one CPA Reference Number. This process meant that the scheme would be assessed as a Managed Pathology Network. This is unique in terms of EQA schemes and presented a number of problems not previously encountered in EQA scheme accreditation. This decision meant that all nine regions must comply with a single Quality Management System and other CPA standards whilst allowing flexibility within the system for each region to facilitate the assessment process specific to their user's requirements. The process worked in a satisfactory manner and the overall outcome was not dissimilar to that of other large EQA schemes. The assessment to the current EQA Standards only commenced in April 2006 whilst the Standards for Medical Laboratories commenced in 2003, and it is perhaps not surprising to find that the principal non-conformities are related to the Quality Management System. This parallels the findings encountered in laboratory accreditation. There is an ongoing educational process for Scheme Management and the Facilitators in each region in how to comply fully with the standards and a commitment to quality improvement which ultimately is beneficial to the participant's of the scheme and to patient safety. [source] CPA assessment , the regional assessors' experienceCYTOPATHOLOGY, Issue 2007G. Guthrie With the introduction in January 2006 of the new posts of Regional Assessors, the process and focus of CPA assessment changed to reflect the inclusion in the current standards of Quality Management systems and processes. Regional Assessors, trained in Quality Management Systems and their assessment against international standards, now form a vital part of the CPA assessment teams, looking specifically at this aspect of laboratory service provision. Their role in the new assessment process will be explained. The presentation will cover differences and similarities in the nature and number of non-compliances experienced since April 2006 when the new format of assessment was introduced. It will also look at a new format of timetable for assessment visits and explain the benefits of good two-way communication between all parties involved in the process - the laboratory, the assessors, particularly the Regional Assessor assigned to that site, and CPA Office staff. Understanding what is required by the standards, particularly in terms of evidential material, their interpretation and their classification of status , Critical, Non-Critical or Observation - is an aspect of assessment which is often not well understood. The presentation will seek to clarify these issues. The successful and timely clearance by laboratories of any non-compliances raised during the visits is vital to the achievement of accredited status and the presentation will give guidance as to how this is best achieved. The current standards, based on the international ISO 15189 standards, are considerably more challenging than the old ones. There is now a significant emphasis on Quality Management and its understanding, ethos and implementation within the laboratory, a key element which underpins all aspects of a laboratory's service. The achievement of accredited status assures our users of,the type of client and patient focused service expected of a modern laboratory. [source] Identification, assessment and intervention,implications of an audit on dyslexia policy and practice in ScotlandDYSLEXIA, Issue 3 2005Gavin Reid Abstract This article reports on research commissioned by the Scottish Executive Education Department (SEED). It aimed to establish the range and extent of policy and provision in the area of specific learning difficulties (SpLD) and dyslexia throughout Scotland. The research was conducted between January and June 2004 by a team from the University of Edinburgh. The information was gathered from a questionnaire sent to all education authorities (100% response rate was achieved). Additional information was also obtained from supplementary interviews and additional materials provided by education authorities. The results indicated that nine education authorities in Scotland (out of 32) have explicit policies on dyslexia and eight authorities have policies on SpLD. It was noted however that most authorities catered for dyslexia and SpLD within a more generic policy framework covering aspects of Special Educational Needs or within documentation on ,effective learning'. In relation to identification thirty-six specific tests, or procedures, were mentioned. Classroom observation, as a procedure was rated high by most authorities. Eleven authorities operated a formal staged process combining identification and intervention. Generally, authorities supported a broader understanding of the role of identification and assessment and the use of standardized tests was only part of a wider assessment process. It was however noted that good practice in identification and intervention was not necessarily dependent on the existence of a dedicated policy on SpLD/dyslexia. Over fifty different intervention strategies/programmes were noted in the responses. Twenty-four authorities indicated that they had developed examples of good practice. The results have implications for teachers and parents as well as those involved in staff development. Pointers are provided for effective practice and the results reflect some of the issues on the current debate on dyslexia particularly relating to early identification.

Andow Abstract By the end of the 1980s, a broad consensus had developed that there were potential environmental risks of transgenic plants requiring assessment and that this assessment must be done on a case-by-case basis, taking into account the transgene, recipient organism, intended environment of release, and the frequency and scale of the intended introduction. Since 1990, there have been gradual but substantial changes in the environmental risk assessment process. In this review, we focus on changes in the assessment of risks associated with non-target species and biodiversity, gene flow, and the evolution of resistance. Non-target risk assessment now focuses on risks of transgenic plants to the intended local environment of release. Measurements of gene flow indicate that it occurs at higher rates than believed in the early 1990s, mathematical theory is beginning to clarify expectations of risks associated with gene flow, and management methods are being developed to reduce gene flow and possibly mitigate its effects. Insect pest resistance risks are now managed using a high-dose/refuge or a refuge-only strategy, and the present research focuses on monitoring for resistance and encouraging compliance to requirements. We synthesize previous models for tiering risk assessment and propose a general model for tiering. Future transgenic crops are likely to pose greater challenges for risk assessment, and meeting these challenges will be crucial in developing a scientifically coherent risk assessment framework. Scientific understanding of the factors affecting environmental risk is still nascent, and environmental scientists need to help improve environmental risk assessment. [source] Influence of sediment ingestion and exposure concentration on the bioavailable fraction of sediment-associated tetrachlorobiphenyl in oligochaetes,ENVIRONMENTAL TOXICOLOGY & CHEMISTRY, Issue 4 2008Arto J. Sormunen Abstract The desorption and bioavailability of 3,3,,4,4,-tetrachlorobiphenyl (PCB 77) were studied in spiked natural sediments at six concentrations. The desorption kinetics were measured in a sediment,water suspension using Tenax® resin extraction, and the bioavailability was measured by exposing Lumbriculus variegatus (Oligochaeta) to PCB 77,spiked sediment in a 14-d kinetic study. In addition, freely dissolved pore-water concentrations were measured using the polyoxymethylene solid-phase extraction method. The present study examined whether bioavailability can be defined more accurately by measuring the size of desorbing fractions and the pore-water concentrations than by using the standard equilibrium partitioning approach. The importance of ingested sediment in bioaccumulation also was investigated. Our data showed a clear, decreasing trend in the rapid-desorbing fractions and in the standard biota,sediment accumulation factors (BSAF) with increasing concentration in sediment. Desorbing fractions,refined BSAFs were more uniform across the concentration treatments, and the pore-water PCB 77 concentration predicted tissue concentrations close to observed values. In the risk assessment process, pore-water concentration or desorbing fractions would lead to more precise bioavailability estimates compared with those from the traditional equilibrium partitioning approach. The result also showed, however, that sediment-ingesting worms had access to an additional bioavailable chemical fraction that was especially evident when PCB 77 pore-water concentrations most likely approached the solubility limit. Thus, feeding may modify the bioavailable fraction that cannot be explained by simple equilibrium partitioning models. [source] Using a Geographic Information System to identify areas with potential for off-target pesticide exposureENVIRONMENTAL TOXICOLOGY & CHEMISTRY, Issue 8 2006Thomas G. Pfleeger Abstract In many countries, numerous tests are required as part of the risk assessment process before chemical registration to protect human health and the environment from unintended effects of chemical releases. Most of these tests are not based on ecological or environmental relevance but, rather, on consistent performance in the laboratory. A conceptual approach based on Geographic Information System (GIS) technology has been developed to identify areas that are vulnerable to nontarget chemical exposure. This GIS-based approach uses wind speed, frequency of those winds, pesticide application rates, and spatial location of agricultural crops to identify areas with the highest potential for pesticide exposure. A test scenario based on an incident in Idaho (USA) was used to identify the relative magnitude of risk from off-target movement of herbicides to plants in the conterminous United States. This analysis indicated that the western portion of the Corn Belt, the central California valley, southeastern Washington, the Willamette Valley of Oregon, and agricultural areas bordering the Great Lakes are among those areas in the United States that appear to have the greatest potential for off-target movement of herbicides via drift. Agricultural areas, such as the Mississippi River Valley and the southeastern United States, appears to have less potential, possibly due to lower average wind speeds. Ecological risk assessments developed for pesticide registration would be improved by using response data from species common to high-risk areas instead of extrapolating test data from species unrelated to those areas with the highest potential for exposure. [source] The EPPO pest risk analysis scheme: comments on using risk scalesEPPO BULLETIN, Issue 1 2010A. MacLeod The pest risk assessment component of the EPPO pest risk analysis (PRA) scheme requires many factors to be considered before the overall risk from a pest or pest-pathway combination is estimated. Each risk factor to consider appears as a question in the risk assessment stage of the PRA scheme. The way in which risk factors are rated within the EPPO scheme are described and compared with two pest risk assessment systems from North America that use rank-order measures to represent composite risk factors during the risk assessment process. It is concluded that a description or metric for each division of a scale that describes the risk factor, for example area occupied, frequency of occurrence and likelihood of an event, would help risk assessors to use the EPPO PRA scheme and should make the risk assessment stage of the scheme more consistent, leading to improved PRAs. [source] Improving clinical assessment: evaluating students' ability to identify and apply clinical criteriaEUROPEAN JOURNAL OF DENTAL EDUCATION, Issue 3 2010C. Redwood Abstract Aim:, There is ongoing concern by health educators over the inability of professionals to accurately self-assess their clinical behaviour and standards, resulting in doubts over a key expectation of effective self-regulation in the health professions. Participation by students in the assessment process has been shown to increase the understanding of assessment criteria in written assessment tasks. How this might transfer to the clinical setting is the focus of this study. This paper is part of an ongoing investigation of the impact on learning of a series of activities that provides students with opportunities to discuss and apply criteria and standards associated with self-assessment in clinical dentistry. Our aim was to evaluate whether participation in these assessment activities improved the ability of first-year dental students to recognise behaviours demonstrated by ,peers' in videos of clinical scenarios and to relate these to the assessment criteria. Materials and methods:, A series of three workshops in conjunction with weekly clinical assessment activities in Semesters 1 and 2 were use to support first-year students' learning of clinical assessment criteria. The design of the workshops was based on the principles of social constructivist theories of learning and the concept of tacit knowledge. Accordingly workshop activities were planned around videos that were specifically constructed to illustrate procedures and behaviours typical of those observed by staff and tutors in the first year of the dental course at The University of Adelaide, Australia. First-year students viewed the videos prior to and after the workshops and recorded observed behaviours that related to the assessment criteria that were used in their clinical practice course. Student learning outcomes were assessed 10,14 weeks after the initial workshop and again up to 42 weeks later. To check whether learning resulted from repeated viewing of the videos without formal discussion, a reference group of third-year students who did not attend the workshops also viewed the videos two times, separated by 12 weeks, and recorded observations in the same way. Results:, There was no consistent evidence that repeat viewing of the videos in isolation resulted in improved recognition of ,peer' behaviours by third-year dental students. Results for the first-year students indicated that the workshops and clinical assessment activities had a significantly positive effect on the ability of students to identify ,peer' behaviours related to the criteria used for clinical assessment. In particular, students' recognition in others of knowledge and professional behaviours improved significantly. This improvement was retained over the year and students were able to recognise these behaviours in other scenarios relevant to their year level. Conclusions:, This early exposure to the process of clinical assessment, coupled with ongoing self-assessment and tutor feedback throughout first year, improved the ability of first-year students to identify and apply some key assessment criteria to observed ,peer' behaviour, and this ability was retained over time.

Schechter This case-study presents in detail the clinical assessment of a 29-year-old mother and her daughter who first presented to infant mental health specialists at age 16 months, with a hospital record suggesting the presence of a dyadic disturbance since age eight months. Data from psychiatric and neurological assessments, as well as observational measures of child and mother, are reviewed with attention to issues of disturbed attachment, intergenerational trauma, and cultural factors for this innercity Latino dyad. Severe maternal affect dysregulation in the wake of chronic, early-onset violent-trauma exposure manifested as psychogenic seizures, referred to in the mother's native Spanish as "ataques de nervios," the latter, an idiom of distress, commonly associated with childhood trauma and dissociation. We explore the mechanisms by which the mothers' reexperiencing of violent traumatic experience, together with physiologic hyperarousal and associated negative affects, are communicated to the very young child and the clinician-observer via action and language from moment to moment during the assessment process. The article concludes with a discussion of diagnostic and treatment implications by Drs. Marshall, Gaensbauer, and Zeanah. ©2003 Michigan Association for Infant Mental Health. [source] Sequential analysis of lines of evidence,an advanced weight-of-evidence approach for ecological risk assessmentINTEGRATED ENVIRONMENTAL ASSESSMENT AND MANAGEMENT, Issue 4 2006Ruth N Hull Abstract Weight-of-evidence (WOE) approaches have been used in ecological risk assessment (ERA) for many years. The approaches integrate various types of data (e.g., from chemistry, bioassay, and field studies) to make an overall conclusion of risk. However, the current practice of WOE has several important difficulties, including a lack of transparency related to how each line of evidence is weighted or integrated into the overall weight-of-evidence conclusion. Therefore, a sequential analysis of lines of evidence (SALE) approach has been developed that advances the practice of WOE. It was developed for an ERA of chemical stressors but also can be used for nonchemical stressors and is equally applicable to the aquatic and terrestrial environments. The sequential aspect of the SALE process is a significant advancement and is based on 2 primary ideas. First, risks can be ruled out with the use of certain lines of evidence, including modeled hazard quotients (HQs) and comparisons of soil, water, or sediment quality with conservative soil, water or sediment quality guidelines. Thus, the SALE process recognizes that HQs are most useful in ruling out risk rather than predicting risk to ecological populations or communities. Second, the SALE process provides several opportunities to exit the risk assessment process, not only when risks are ruled out, but also when magnitude of effect is acceptable or when little or no evidence exists that associations between stressors and effects may be causal. Thus, the SALE approach explicitly includes interaction between assessors and managers. It illustrates to risk managers how risk management can go beyond the simple derivation of risk-based concentrations of chemicals of concern to risk management goals based on ecological metrics (e.g., species diversity). It also can be used to stimulate discussion of the limitations of the ERA science, and how scientists deal with uncertainty. It should assist risk managers by allowing their decisions to be based on a sequential, flexible, and transparent process that includes direct toxicity risks, indirect risks (via changes in habitat suitability), and the spatial and temporal factors that can influence the risk assessment. [source] A critical assessment of the ecological risk assessment process: A review of misapplied conceptsINTEGRATED ENVIRONMENTAL ASSESSMENT AND MANAGEMENT, Issue 1 2005Lawrence V. Tannenbaum Abstract A frank assessment of present-day ecological risk assessments (ERA) for managed contaminated sites reveals that fundamental concepts regarding the receptors that are considered and the chemical exposures they experience are commonly misapplied. As a consequence, environmental managers are not being supplied with the information needed for proper decision making. The stepwise review of ecological risk issues provided here suggests that the ERA process needs to be severely revamped. Further, what is likely hindering the development of a refined ecological assessment process that is better suited to environmental problem solving and land management is the unwillingness of stakeholders to agree that much of the current ERA practice and convention is flawed. [source] Review of assessment and treatment of PTSD among elderly American armed forces veteransINTERNATIONAL JOURNAL OF GERIATRIC PSYCHIATRY, Issue 12 2005Gina P. Owens Abstract Background The number of elderly combat veterans is steadily increasing in the US and estimates project that a notable percentage of these veterans experience symptoms of posttraumatic stress disorder (PTSD). Limited data exist specifically related to prevalence, assessment, and treatment of PTSD among the elderly veteran population. Objective This review summarizes the available research related to difficulties in assessment with the elderly American Armed Forces veteran population. In addition, both psychotherapeutic and pharmacological treatment interventions for PTSD are discussed. Methods A literature search was conducted using PsycINFO, Medline, and the National Center for PTSD's PILOTS database. Results Evidence suggests that elderly veterans generally present more somatic symptoms of PTSD. Medical and psychological comorbodities, such as depression, substance abuse, or cognitive deficits can further complicate the assessment process. Cut-scores for existing instruments need to be further established with elderly veterans. Use of exposure therapies with the elderly has not been adequately researched and mixed results have been obtained for supportive therapy for treatment of PTSD. Controlled research investigating pharmacological interventions for PTSD with the elderly is also limited. Conclusion Evidence suggests that some psychotherapeutic and pharmacological interventions already utilized with younger individuals may be useful with the elderly veteran population. However, research indicates that modifications may be required for working with the elderly population and further research in the areas of assessment and treatment are necessary.

[source] Does assessment make a difference for people with dementia?INTERNATIONAL JOURNAL OF GERIATRIC PSYCHIATRY, Issue 3 2003The effectiveness of the Aged Care Assessment Teams in Australia Abstract The needs of individuals with dementia and other psychiatric problems of old age have received increased attention in Australia over the last decade. This paper reports on the role of Aged Care Assessment Teams (ACATs) in managing these clients, and the extent to which they are differentiated from other clients in the assessment process and outcomes recommended. Data on some 26,500 clients seen by ACATs in Victoria in the second half of 1999 are analysed to show (1) the relationship between a diagnosis of dementia and reporting of disability in orientation, (2) characteristics of clients with and without a diagnosis of dementia and (3) outcomes for groups of clients defined on the basis of a diagnosis of dementia and disability in orientation.

Ufuk Bilsel This article presents a quality evaluation model for measuring the performance of hospital Web sites. The model is developed on the basis of a conceptual framework, which consists of seven major e-service quality dimensions, including tangibles, reliability, responsiveness, confidence, empathy, quality of information, and integration of communication issues of Web sites. The dimensions and their associated attributes are first obtained from published articles in the health care and information technology literature and then adapted according to the suggestions of related domain experts. Two multicriteria decision-making methods are used in the evaluation procedure. Determined Web site evaluation dimensions and their relevant attributes are weighted using the Analytic Hierarchy Process (AHP) method. Vagueness in some stages of the evaluation required the incorporation of fuzzy numbers in the assessment process. Both fuzzy and crisp data are then synthesized using the fuzzy PROMETHEE (Preference Ranking Organization Method for Enrichment Evaluation) ranking method. The model is applied initially to measure the performance of the Web sites of Turkish hospitals. This study should be of interest to health care and technology practitioners and researchers, as the findings shed light on the further development of performance measurements for hospital Web sites. © 2006 Wiley Periodicals, Inc.

Keane Attempts to control the importation of infectious diseases through the medical screening and evaluation of immigrants and refugees represent the modern application of some of the earliest recorded public health interventions. States with long-standing immigration programmes continue to require the medical examination and screening of migrants for certain diseases. In some instances, the public health effectiveness of these immigration medical assessments is of questionable value when considered from a population health basis. This article reviews current practices and describes recent studies where more modern and epidemiologically based immigration medical interventions have been undertaken. A more effective immigration medical assessment process is proposed through the use of results of this more empirical approach to immigration medical screening. [source] An evaluation of community and corporate bias in assessment toolsINTERNATIONAL SOCIAL SCIENCE JOURNAL, Issue 189 2006Irmgard Bauer This is a comprehensive review and evaluation of the main international and national tools utilised to assess the impact of developments on communities to determine their validity of their capacity to detect and measure impacts across a wide spectrum of community resources. Manuals from environmental, health and social impact assessment were reviewed. The criteria for evaluation were the type of indicators used in the tool; the stage at which communities were involved in the assessment process and whether assessments were completed from an insider (local) or outsider (expert) perspective. The findings were that few guidelines include detail in measuring, monitoring, and including community-validated indicators. It is still rare to find impact assessments that include criteria that are meaningful to the community rather than to the developer or outside expert. While the need to include the target community in the assessment process has been acknowledged over the last 10 to 20 years the rigorous work required for the development of criteria to validate community-driven assessment still needs to be completed.

Maurer MD Although there is a critical need to prepare physicians to care for the growing population of older adults, many academic medical centers lack the geriatric-trained faculty and dedicated resources needed to support comprehensive residency training programs in geriatrics. Because of this challenge at Columbia University, the Columbia Cooperative Aging Program was developed to foster geriatric training for medical interns. For approximately 60 interns each year completing their month-long geriatric rotations, an integral part of this training now involves conducting comprehensive assessments with "well" older people, supervised by an interdisciplinary team of preceptors from various disciplines, including cardiology, internal medicine, occupational therapy, geriatric nursing, psychiatry, education, public health, social work, and medical anthropology. Interns explore individual behaviors and social supports that promote health in older people; older people's strengths, vulnerabilities, and risk for functional decline; and strategies for maintaining quality of life and independence. In addition, a structured "narrative medicine" writing assignment is used to promote the interns' reflections on the assessment process, the data gathered, and their clinical reasoning throughout. Preliminary measures of the program's effect have shown significant improvements in attitudes toward, and knowledge of, older adults as patients, as well as in interns' self-assessed clinical skills. For academic medical centers, where certified geriatric providers are scarce, this approach may be an effective model for fostering residency geriatric education among interns. [source] Using ants as bioindicators in land management: simplifying assessment of ant community responsesJOURNAL OF APPLIED ECOLOGY, Issue 1 2002Alan N. Andersen Summary 1The indicator qualities of terrestrial invertebrates are widely recognized in the context of detecting ecological change associated with human land-use. However, the use of terrestrial invertebrates as bioindicators remains more a topic of scientific discourse than a part of land-management practice, largely because their inordinate numbers, taxonomic challenges and general unfamiliarity make invertebrates too intimidating for most land-management agencies. Terrestrial invertebrates will not be widely adopted as bioindicators in land management until simple and efficient protocols have been developed that meet the needs of land managers. 2In Australia, ants are one group of terrestrial insects that has been commonly adopted as bioindicators in land management, and this study examined the reliability of a simplified ant assessment protocol designed to be within the capacity of a wide range of land managers. 3Ants had previously been surveyed intensively as part of a comprehensive assessment of biodiversity responses to SO2 emissions from a large copper and lead smelter at Mt Isa in the Australian semi-arid tropics. This intensive ant survey yielded 174 species from 24 genera, and revealed seven key patterns of ant community structure and composition in relation to habitat and SO2 levels. 4We tested the extent to which a greatly simplified ant assessment was able to reproduce these results. Our simplified assessment was based on ant ,bycatch' from bucket-sized (20-litre) pitfall traps used to sample vertebrates as part of the broader biodiversity survey. We also greatly simplified the sorting of ant morphospecies by considering only large (using a threshold of 4 mm) species, and we reduced sorting time by considering only the presence or absence of species at each site. In this manner, the inclusion of ants in the assessment process required less than 10% of the effort demanded by the intensive ant survey. 5Our simplified protocol reproduced virtually all the key findings of the intensive survey. This puts effective ant monitoring within the capacity of a wide range of land managers. [source] The Reliability, Validity and Practical Utility of Measuring Supports using the I-CAN Instrument: Part IIJOURNAL OF APPLIED RESEARCH IN INTELLECTUAL DISABILITIES, Issue 4 2009Vivienne C. Riches Background, There is an urgent need for developing reliable, valid and practical instruments that assess and classify the support needed by persons with disability to function in their chosen living, working and social environments. I-CAN is an instrument that addresses the frequency and level of support needed (not individual skills or deficits) for each individual with a disability. Method, Studies were conducted to assess the test,retest reliability and inter-rater reliability. Concurrent validity was investigated by exploring the relationship between the I-CAN domain scales and the Inventory for Client and Agency Planning (ICAP) (Bruininks et al. 1986) and the Quality of Life Questionnaire (QOL-Q) (Schalock & Keith 1993). Predictive validity studies were undertaken using day- and night-time support hours. Regression analyses were run using these measures with I-CAN domain scales. Two independent studies were also conducted to ascertain the practical utility of the instrument. Results, The I-CAN instrument demonstrated excellent inter-rater and test,retest reliability in the Activities and Participation domains. Low-to-moderate test,retest results in Physical Health, Mental Emotional Health and Behaviour domains were tracked to actual change in support needs in these areas. Validity proved acceptable. The relationships between I-CAN domain scales and adaptive behaviour were mixed but in the expected direction. Low-to-moderate correlation coefficients were evident between the I-CAN scales and the QOL-Q Total, but greater support needed in certain domains was associated with less empowerment and independence, and less community integration and social belonging. Attempts to explain current support hours against the I-CAN scales were disappointing and suggest that a number of other factors apart from individual support need to play a significant role. There was general satisfaction with the assessment process from stakeholders and participant groups. Conclusions, I-CAN is a reliable, valid and user-friendly instrument for assessing the support needs of people with disabilities. It uses a process that involves the persons with disability, their family and friends and staff as appropriate. It is also apparent that the current provision of paid support hours by agencies is a complex phenomenon that is not based solely on individual support needs. Further research is warranted on the influence of the environment and the perceptions of need for support based on negotiable and non-negotiable support needs.

This was achieved through the provision of appropriate staff education and information, assessment of staff competence, and provision of relevant and appropriate staff support. ,,An education programme was developed which included study days, ward-based teaching and the assessment of competence. ,,The introduction of guidelines followed an audit cycle in order to measure the success of the education programme. ,,All nursing staff involved in the project were asked to complete a questionnaire which assessed their knowledge of caring for patients with postoperative epidural analgesia. This was completed before and following the education programme. ,,The outcome measures were: (i) successful completion of competence-based assessment; (ii) levels of knowledge as assessed by the knowledge questionnaire; and (iii) participant perceptions of the project. ,,The results of the questionnaire demonstrated significant improvements in knowledge following the education programme. Participants commented on the importance of the ward-based teaching. They also felt that pain was controlled more effectively using this method of analgesia. [source] Analytical epidemiology of periodontitisJOURNAL OF CLINICAL PERIODONTOLOGY, Issue 2005Luisa N. Borrell Abstract Aims: To review the literature related to the analytical epidemiology of periodontitis generated over the past decade. This review does not deal with descriptive epidemiologic studies of the prevalence, extent and severity of periodontitis with respect to global geography, but focuses exclusively on analytical epidemiology issues, including the challenges posed by the use of different case definitions across studies, current theories and models of disease progression, and risk factors associated with the onset and progression of periodontitis. Methods: Relevant publications in the English language were identified after Medline and PubMed database searches. Findings and conclusions: There is a conspicuous lack of uniformity in the definition of periodontitis used in epidemiologic studies, and findings from different research groups are not readily interpretable. There is a lack of studies that specifically address the distinction between factors responsible for the onset of periodontitis versus those affecting its progression. Colonization by specific bacteria at high levels, smoking, and poorly controlled diabetes have been established as risk factors for periodontitis, while a number of putative factors, including specific gene polymorphisms, have been identified in association studies. There is a clear need for longitudinal prospective studies that address hypotheses emerging from the cross-sectional data and include established risk factors as covariates along with new exposures of interest. Intervention studies, fulfilling the "targeting" step of the risk assessment process, are particularly warranted. Obvious candidates in this context are studies of the efficacy of elimination of specific bacterial species and of smoking cessation interventions as an alternative to the traditional broad anti-plaque approach in the prevention and control of periodontitis. Ideally, such studies should have a randomized-controlled trial design. [source] Evidence-Based assessment with menJOURNAL OF CLINICAL PSYCHOLOGY, Issue 6 2005Sam V. Cochran Men are almost universally underrepresented in psychological clinics and practices in the United States. One possible explanation for this underrepresentation is that men frequently conceal or obscure their emotional difficulties as a consequence of masculine gender role socialization. Men who subscribe to traditional, Western masculine values may be inclined to hide, minimize, or otherwise have difficulty expressing their psychological suffering, rendering this suffering difficult for clinicians to observe, diagnose, and treat. This manuscript describes an approach to the assessment process with men that integrates clinical reports on assessment and psychotherapy with men, values pertaining to our culture's construction of traditional masculinity, and empirical findings on psychological disorders more commonly observed in men. © 2005 Wiley Periodicals, Inc.

Second, what managers consider as being of value follows from how they organize their managerial practice. Based on a case study of a Swedish public transportation administration, a claim is presented that organizational risk conceptions derive primarily, although not exclusively, from what managers consider being of value both in and for their organizational practice. In particular, it is suggested to begin the risk assessment process with a critical appraisal of what managers hold as being of value and why. [source] Simulation and multi-attribute utility modelling of life cycle profitJOURNAL OF MULTI CRITERIA DECISION ANALYSIS, Issue 4 2001Tony RosqvistArticle first published online: 16 NOV 200 Abstract Investments on capital goods are assessed with respect to the life cycle profit as well as the economic lifetime of the investment. The outcome of an investment with respect to these economic criteria is generally non-deterministic. An assessment of different investment options thus requires probabilistic modelling to explicitly account for the uncertainties. A process for the assessment of life cycle profit and the evaluation of the adequacy of the assessment is developed. The primary goal of the assessment process is to aid the decision-maker in structuring and quantifying investment decision problems characterized by multiple criteria and uncertainty. The adequacy of the assessment process can be evaluated by probabilistic criteria indicating the degree of uncertainty in the assessment. Bayesian inference is used to re-evaluate the initial assessment, as evidence of the system performance becomes available. Thus authentication of contracts of guarantee is supported. Numerical examples are given to demonstrate features of the described life cycle profit assessment process. Copyright © 2001 John Wiley & Sons, Ltd. [source] Clinical formulation for mental health nursing practiceJOURNAL OF PSYCHIATRIC & MENTAL HEALTH NURSING, Issue 10 2008M. Crowe rn phd There are problems for mental health nurses in using psychiatric diagnoses as outcomes of their nursing assessments and nursing diagnoses present similar issues. However, there is a need in practice to link the assessment to nursing interventions in a meaningful way. This paper proposes that the clinical formulation can be regarded as central to providing this cohesion. The formulation does not merely organize the assessment findings but is also an interpretation or explanation, made in consultation with the client, of what meaning can be attributed to the issues explored in the assessment process. Because this interpretation is dependent on both the client's and the nurse's explanatory frameworks, there are multiple ways of developing the formulation. It is also an evolving and dynamic statement of understanding. A case example is provided in the paper to illustrate how the same case can be interpreted in different ways and the implications this has for the nursing interventions provided. [source] Preservice elementary teachers' views of their students' prior knowledge of scienceJOURNAL OF RESEARCH IN SCIENCE TEACHING, Issue 4 2008Valerie K. Otero Abstract Pre-service teachers face many challenges as they learn to teach in ways that are different from their own educational experiences. Pre-service teachers often enter teacher education courses with pre-conceptions about teaching and learning that may or may not be consistent with contemporary learning theory. To build on preservice teachers' prior knowledge, we need to identify the types of views they have when entering teacher education courses and the views they develop throughout these courses. The study reported here focuses specifically on preservice teachers' views of their own students' prior knowledge and the implications these views have on their understanding of the formative assessment process. Sixty-one preservice teachers were studied from three sections of a science methods course. Results indicate that preservice teachers exhibited a limited number of views about students' prior knowledge. These views tended to privilege either academic or experience-based concepts for different aspects of formative assessment, in contrast to contemporary perspectives on teaching for understanding. Rather than considering these views as misconceptions, it is argued that it is more useful to consider them as resources for further development of a more flexible concept of formative assessment. Four common views are discussed in detail and applied to science teacher education. © 2008 Wiley Periodicals, Inc.

Tsengwen reservoir, located in the Tsengwen creek watershed, is a multipurpose reservoir with a primary function to supply water for the ChiaNan Irrigation District. A simulation procedure was developed to evaluate the impacts of climate change on the water resources system. The simulation procedure includes a streamflow model, a weather generation model, a sequent peak algorithm, and a risk assessment process. Three climate change scenarios were constructed based on the predictions of three General Circulation Models (CCCM, GFDL, and GISS). The impacts of climate change on streamflows were simulated, and, for each climate change scenario, the agricultural water demand was adjusted based on the change of potential evapotranspiration. Simulation results indicated that the climate change may increase the annual and seasonal streamflows in the Tsengwen creek watershed. The increase in streamflows during wet periods may result in serious flooding. In addition, despite the increase in streamflows, the risk of water deficit may still increase from between 4 and 7 percent to between 7 and 13 percent due to higher agricultural water demand. The simulation results suggest that the reservoir capacity may need to be expanded. In response to the climate change, four strategies are suggested: (1) strengthen flood mitigation measures, (2) enhance drought protection strategies, (3) develop new water resources technology, and (4) educate the public. [source] Use of a structured interview to assess portfolio-based learningMEDICAL EDUCATION, Issue 9 2008Vanessa C Burch Context, Portfolio-based learning is a popular educational tool usually examined by document review which is sometimes accompanied by an oral examination. This labour-intensive assessment method prohibits its use in the resource-constrained settings typical of developing countries. Objectives, We aimed to determine the feasibility and internal consistency of a portfolio-based structured interview and its impact on student learning behaviour. Methods, Year 4 medical students (n = 181) recorded 25 patient encounters during a 14-week medical clerkship. Portfolios were examined in a 30-minute, single-examiner interview in which four randomly selected cases were discussed. Six standard questions were used to guide examiners in determining the ability of candidates to interpret and synthesise clinical data gathered during patient encounters. Examiners were trained to score responses using a global rating scale. Pearson's correlation co-efficient, Cronbach's , coefficient and the standard error of measurement (SEM) of the assessment tool were determined. The number of students completing more than the required number of portfolio entries was also recorded. Results, The mean (± standard deviation [SD], 95% confidence interval [CI]) interview score was 67.5% (SD ± 10.5, 95% CI 66.0,69.1). The correlation coefficients for the interview compared with other component examinations of the assessment process were: multiple-choice question (MCQ) examination 0.42; clinical case-based examination 0.37; in-course global rating 0.08, and overall final score 0.54. Cronbach's , coefficient was 0.88 and the SEM was 3.6. Of 181 students, 45.3% completed more than 25 portfolio entries. Conclusions, Portfolio assessment using a 30-minute structured interview is a feasible, internally consistent assessment method that requires less examination time per candidate relative to methods described in published work and which may encourage desirable student learning behaviour. [source] Psychosocial treatment refusal in personality disorder: a comparative studyPERSONALITY AND MENTAL HEALTH, Issue 2 2010Marco Chiesa There is a paucity of research concerning the identification of features implicated in treatment refusal by personality disorder. This study aims to identify clinical factors that may affect treatment uptake to a specialist psychosocial programme for personality disorder. Following a lengthy assessment, 39 patients (out of a total of 60 referrals) were offered entry to the programme. Fourteen patients who did not take up the offer of treatment and 25 patients who started the programme are compared on a number of demographic, diagnostic and clinical variables, including severity of presentation and subjective experience of the assessment process. The results show that, relative to non-refusers, refusers were significantly younger, single, had a higher frequency of borderline personality disorder (BPD), experienced a less satisfactory relationship with the assessing clinician and had lower treatment expectations. Several dimensions measuring severity of presentation did not make a significant contribution to treatment uptake. A logistic regression analysis showed that assessment-related variables total score and BPD were significant predictors of treatment refusal. The low sample size and the specialist nature of the service are important limitations with regard to the generalizability of the findings. Copyright © 2010 John Wiley & Sons, Ltd.
