Appropriate Measures (appropriate + measure)
Selected AbstractsInitialization Strategies in Simulation-Based SFE Eigenvalue AnalysisCOMPUTER-AIDED CIVIL AND INFRASTRUCTURE ENGINEERING, Issue 5 2005Song Du Poor initializations often result in slow convergence, and in certain instances may lead to an incorrect or irrelevant answer. The problem of selecting an appropriate starting vector becomes even more complicated when the structure involved is characterized by properties that are random in nature. Here, a good initialization for one sample could be poor for another sample. Thus, the proper eigenvector initialization for uncertainty analysis involving Monte Carlo simulations is essential for efficient random eigenvalue analysis. Most simulation procedures to date have been sequential in nature, that is, a random vector to describe the structural system is simulated, a FE analysis is conducted, the response quantities are identified by post-processing, and the process is repeated until the standard error in the response of interest is within desired limits. A different approach is to generate all the sample (random) structures prior to performing any FE analysis, sequentially rank order them according to some appropriate measure of distance between the realizations, and perform the FE analyses in similar rank order, using the results from the previous analysis as the initialization for the current analysis. The sample structures may also be ordered into a tree-type data structure, where each node represents a random sample, the traverse of the tree starts from the root of the tree until every node in the tree is visited exactly once. This approach differs from the sequential ordering approach in that it uses the solution of the "closest" node to initialize the iterative solver. The computational efficiencies that result from such orderings (at a modest expense of additional data storage) are demonstrated through a stability analysis of a system with closely spaced buckling loads and the modal analysis of a simply supported beam. [source] Assessment of motor development and function in preschool childrenDEVELOPMENTAL DISABILITIES RESEARCH REVIEW, Issue 3 2005Beth L. Tieman Abstract The process of identification of children with delays or disorders in motor development includes developmental screening, examination, and reexamination. Throughout this process, various types of measures are used, including discriminative and evaluative measures. Discriminative and evaluative measures of motor development and function that are commonly used for preschool-aged children include the Bayley Scales of Infant Development II, Peabody Developmental Motor Scales, 2nd edition, Toddler and Infant Motor Evaluation, Pediatric Evaluation of Disability Inventory, and Gross Motor Function Measure. Selecting an appropriate measure is a crucial part of the examination process and should be geared toward the purpose of testing and characteristics of the child. Evidence of reliability and validity are important considerations for selection of a measure. © 2005 Wiley-Liss, Inc. MRDD Research Reviews 2005;11:189,196. [source] The assessment of behavioural activation,the relationship between positive emotionality and the behavioural activation systemEUROPEAN JOURNAL OF PERSONALITY, Issue 7 2004Lena C. Quilty Much personality research suggests that the variance in personality can be accounted for by a few dimensions, often hypothesized to be connected to neurological circuits. Gray's (1982) behavioural activation system (BAS) and behavioural inhibition system (BIS) in particular propose to explain for a variety of behaviour. This investigation sought to determine whether Positive Emotionality is an appropriate measure of the BAS, and how Tellegen's (1985) constructs are related to BAS activity. Measures of BAS and Positive Emotionality were administered to undergraduates. Confirmatory factor analyses revealed that, while Positive Emotionality can be used as an indicator of BAS activity, it is better conceived of as a distinct, correlated construct. In addition, not all components of Positive Emotionality were related to BAS activity, and BAS was further related to components of Negative Emotionality and Constraint.

[source] THE ADAPTIVE DYNAMICS OF ALTRUISM IN SPATIALLY HETEROGENEOUS POPULATIONSEVOLUTION, Issue 1 2003JEAN-FRANÇOIS LE GALLIARD Abstract., We study the spatial adaptive dynamics of a continuous trait that measures individual investment in altruism. Our study is based on an ecological model of a spatially heterogeneous population from which we derive an appropriate measure of fitness. The analysis of this fitness measure uncovers three different selective processes controlling the evolution of altruism: the direct physiological cost, the indirect genetic benefits of cooperative interactions, and the indirect genetic costs of competition for space. In our model, habitat structure and a continuous life cycle makes the cost of competing for space with relatives negligible. Our study yields a classification of adaptive patterns of altruism according to the shape of the costs of altruism (with decelerating, linear, or accelerating dependence on the investment in altruism). The invasion of altruism occurs readily in species with accelerating costs, but large mutations are critical for altruism to evolve in selfish species with decelerating costs. Strict selfishness is maintained by natural selection only under very restricted conditions. In species with rapidly accelerating costs, adaptation leads to an evolutionarily stable rate of investment in altruism that decreases smoothly with the level of mobility. A rather different adaptive pattern emerges in species with slowly accelerating costs: high altruism evolves at low mobility, whereas a quasi-selfish state is promoted in more mobile species. The high adaptive level of altruism can be predicted solely from habitat connectedness and physiological parameters that characterize the pattern of cost. We also show that environmental changes that cause increased mobility in those highly altruistic species can beget selection-driven self-extinction, which may contribute to the rarity of social species. [source] Capital Allocation and Risk Performance Measurement In a Financial InstitutionFINANCIAL MARKETS, INSTITUTIONS & INSTRUMENTS, Issue 5 2000Stuart M. Turnbull This paper provides an analytical and practical framework, consistent with maximizing the wealth of existing shareholders, to address the following questions: What are the costs associated with economic capital? What is the tradeoff between the probability of default and the costs of economic capital? How do we take into account the time profile of economic capital when assessing the performance of a business? What is the appropriate measure of profitability, keeping the probability of default constant? It is shown that the capital budgeting decision depends not only on the covariance of the return of a project with the market portfolio, but also on the covariance with the bank's existing assets. This dependency arises from the simple fact that the economic capital is not additive. [source] Employment of People with Disabilities Following the ADAINDUSTRIAL RELATIONS, Issue 1 2003Douglas Kruse Studies finding a negative effect of the Americans with Disabilities Act (ADA) on the employment of people with disabilities have used the work disability measure, which has several potential problems in measuring employment trends. Using Survey of Income and Program Participation (SIPP) data that permit alternative measures of disability, this study finds decreased employment among those reporting work disabilities in the first few years after the ADA was passed but increased employment when using a more probably appropriate measure of ADA coverage (functional and activity limitations that do not prevent work). State-by-state variation in labor market tightness is used to find that people with disabilities may have especially procyclical employment, but the contrary results in overall employment trends remain after accounting for labor market tightness. Given the problems in measuring who is covered by the ADA, there is reason to be cautious of both positive and negative findings. [source] A Fiscal Price Tag for International Reserves,INTERNATIONAL FINANCE, Issue 2 2006David Hauner This paper examines the (quasi-)fiscal impact of the (opportunity) cost of international reserves. It proposes a conceptual framework, with particular emphasis on two hitherto somewhat neglected aspects: a more appropriate measure of gross opportunity cost, and potential savings from lower external debt spreads that countries ,buy' by holding reserves. The framework is then applied to 100 countries over 1990,2004. The results suggest that a turning point has been reached in recent years: while most countries made money on their reserves during 1990,2001, most have been losing money during 2002,04. [source] The role of group size and environmental factors on survival in a cooperatively breeding tropical passerineJOURNAL OF ANIMAL ECOLOGY, Issue 6 2006LYANNE BROUWER Summary 1Variation in survival, a major determinant of fitness, may be caused by individual or environmental characteristics. Furthermore, interactions between individuals may influence survival through the negative feedback effects of density dependence. Compared to species in temperate regions, we have little knowledge about population processes and variation in fitness in tropical bird species. 2To investigate whether variation in survival could be explained by population size or climatic variables we used capture,recapture models in conjunction with a long-term data set from an island population of the territorial, cooperatively breeding Seychelles warbler (Acrocephalus sechellensis). The lack of migration out of the study population means that our results are not confounded by dispersal. 3Annual survival was high, both for adults (84%) and juveniles (61%), and did not differ between the sexes. Although there was significant variation in survival between years, this variation could not be explained by overall population size or weather variables. 4For territorial species, resource competition will work mainly on a local scale. The size of a territory and number of individuals living in it will therefore be a more appropriate measure of density than overall population density. Consequently, both an index of territory quality per individual (food availability) and local density, measured as group size, were included as individual covariates in our analyses. 5Local density had a negative effect on survival; birds living in larger groups had lower survival probabilities than those living in small groups. Food availability did not affect survival. 6Our study shows that, in a territorial species, although density-dependent effects might not be detectable at the population level they can be detected at the individual territory level , the scale at which individuals compete. These results will help to provide a better understanding of the small-scale processes involved in the dynamics of a population in general, but in particular in tropical species living in relatively stable environments. [source] Current International Approaches to Food ClaimsNUTRITION REVIEWS, Issue 12 2000No-Seong Kwak Ph.D. The market for functional foods is rapidly increasing. It is necessary to establish a legal framework for these foods. This has proved difficult in a number of countries. The control through health claims is generally accepted as the most appropriate measure. Activity in this area has been developing both at the national and international levels. However, the regulations and proposals from a number of national authorities and other nongovernmental sectors are varied and difficult to reconcile. This paper examines the range of health claim controls being used in the food area. They are considered in detail so as to establish a better understanding of the claims. In this paper, the claims have been classified into six categories: nutrient content claims, comparative claims, nutrient function claims, claims related to dietary guidelines or healthy diets, enhanced function claims, and reduction of disease risk claims. Of these, the latter four claims are considered to have significant implications for functional foods. [source] Modelling the role of social behavior in the persistence of the alpine marmot Marmota marmotaOIKOS, Issue 1 2003Volker Grimm A general rule of thumb for biological conservation obtained from simple models of hypothetical species is that for populations with strong environmental noise moderate increases in habitat size or quality do not substantially reduce extinction risk. However, whether this rule also holds for real species with complex behavior, such as social species with breeding units and reproductive suppression, is uncertain. Here we present a population viability analysis of the alpine marmot Marmota marmota, which displays marked social behavior, i.e. it lives in social groups of up to twenty individuals. Our analysis is based on a long-term field study carried out in the Bavarian Alps since 1982. During the first fifteen years of this study, 687 marmots were individually marked and the movements and fate of 98 dispersing marmots were recorded with radio-telemetry. Thus, in contrast to most other viability analyses of spatially structured populations, good data about dispersal exist. A model was constructed which is individual-based, spatially explicit at the scale of clusters of neighbouring territories, and spatially implicit at larger scales. The decisive aspect of marmot life history, winter mortality, is described by logistic regression where mortality is increased by age and the severity of winter, and decreased by the number of subdominant individuals present in a group. Model predictions of group size distribution are in good agreement with the results of the field study. The model shows that the effect of sociality on winter mortality is very effective in buffering environmental harshness and fluctuations. This underpins theoretical results stating that the appropriate measure of the strength of environmental noise is the ratio between the variance of population growth rate and the intrinsic rate of increase. The lessons from our study for biological conservation are that simple, unstructured models may not be sufficient to assess the viability of species with complex behavioral traits, and that even moderate increases in habitat capacity may substantially reduce extinction risk even if environmental fluctuations seem high. [source] Canada-United States interregional trade: quasi-points and spatial changeTHE CANADIAN GEOGRAPHER/LE GEOGRAPHE CANADIEN, Issue 2 2010MARTIN A. ANDRESEN commerce interrégional; profil des échanges commerciaux; libre échange; Monte Carlo Interregional trade between Canada and the United States has undergone significant change since the inception of free trade. However, the magnitude of that change for the different regions in Canada and the United States has not been properly identified because of a lack of an appropriate measure. This paper introduces the concept of a quasi-point and employs a spatial point pattern test to measure the degree of change in the interregional trade of Canadian provinces and US states, with an emphasis of that change on Ontario. It is found that the degree of change in the interregional trade flows is related to the degree of change in the provincial tariff rates. Les échanges commerciaux interrégionaux entre le Canada et les États-Unis: les quasi-points et les changements spatiaux D'importants changements ont été observés dans le marché canado-américain depuis l'entrée en vigueur du libre-échange. Toutefois, on ne dispose pas de moyen valide pour évaluer l'ampleur des changements à l'échelle des régions nord-américaines. Ainsi, cet article propose le concept du quasi-point et repose sur une étude de la répartition spatiale de points afin d'évaluer l'évolution des échanges commerciaux interrégionaux entre chacune des provinces canadiennes et les autres provinces du Canada ainsi que les états des États-Unis. L'évolution des flux d'échanges commerciaux dépend en effet de l'évolution des droits tarifaires imposés par les provinces. [source] Consumption and Income Inequality in AustraliaTHE ECONOMIC RECORD, Issue 233 2000GARRY F. BARRETT Consumption may be a more appropriate measure of household well-being than income or earnings. Using four ABS Household Expenditures Surveys collected between 1975 and 1993, we compare trends in consumption and income inequality among Australian households. We find that consumption is much more equal than income. While there were significant increases in both income and consumption inequality, consumption inequality rose by much less. One interpretation of the results is that some income inequality in Australia reflects transitory fluctuations which households can smooth,,and that part of the growth in income inequality reflects an increase in these transitory fluctuations. [source] Original Article: Audit of severe acute maternal morbidity describing reasons for transfer and potential preventability of admissions to ICUAUSTRALIAN AND NEW ZEALAND JOURNAL OF OBSTETRICS AND GYNAECOLOGY, Issue 4 2010Beverley A. LAWTON Background:, Maternal mortality is a rare event in the developed world. Assessment of severe acute maternal morbidity (SAMM) is therefore an appropriate measure of the quality of maternity care. Aims:, The aim of the study was to conduct a retrospective audit of SAMM cases (pregnant women admitted to a New Zealand Intensive Care Unit) to describe clinical, socio-demographic characteristics, pregnancy outcomes and preventability. Methods:, Severe acute maternal morbidity cases were reviewed by a multidisciplinary panel to determine reasons for admission to ICU, to classify organ-system dysfunction and to determine whether the SAMM case was preventable or not. Inclusion criteria were: admission to ICU between 2005 and 2007 during pregnancy or within 42 days of delivery. Results:, Twenty-nine SAMM cases were reviewed, of which 10 (35%) were deemed preventable. The most common reasons for transfer to ICU were: the need for invasive vascular monitoring, hypotension and disseminated intravascular coagulation. The most frequent types of preventable events were: inadequate diagnosis/recognition of high-risk status, inappropriate treatment, communication problems and inadequate documentation. All five SAMM cases of septicaemia were deemed preventable. Of the ten preventable cases, three were Maori (50% of the Maori in total audit), four were Pacific (67% of the Pacific in total audit) and three were women of ,other' ethnicities (17.6%, 3 of 17 in the audit). Conclusions:, An audit of SAMM cases describing reasons for transfer to ICU and preventability is feasible. We recommend that a prospective national SAMM audit process be introduced in New Zealand as a quality of care measure. [source] Proposal for a standardised identification of the mono-exponential terminal phase for orally administered drugsBIOPHARMACEUTICS AND DRUG DISPOSITION, Issue 3 2008Christian Scheerans Abstract The area under the plasma concentration-time curve from time zero to infinity (AUC0,inf) is generally considered to be the most appropriate measure of total drug exposure for bioavailability/bioequivalence studies of orally administered drugs. However, the lack of a standardised method for identifying the mono-exponential terminal phase of the concentration-time curve causes variability for the estimated AUC0,inf. The present investigation introduces a simple method, called the two times tmax method (TTT method) to reliably identify the mono-exponential terminal phase in the case of oral administration. The new method was tested by Monte Carlo simulation in Excel and compared with the adjusted r squared algorithm (ARS algorithm) frequently used in pharmacokinetic software programs. Statistical diagnostics of three different scenarios, each with 10,000 hypothetical patients showed that the new method provided unbiased average AUC0,inf estimates for orally administered drugs with a monophasic concentration-time curve post maximum concentration. In addition, the TTT method generally provided more precise estimates for AUC0,inf compared with the ARS algorithm. It was concluded that the TTT method is a most reasonable tool to be used as a standardised method in pharmacokinetic analysis especially bioequivalence studies to reliably identify the mono-exponential terminal phase for orally administered drugs showing a monophasic concentration-time profile.

Thomas This article analyses the past, present and future of these institutions, which were created to assist Parliament in holding responsible ministers and the bureaucracy accountable and to protect certain rights of individual Canadians. The fundamental issue is how to balance these offices' independence from both the executive and Parliament with an appropriate measure of accountability for their performance. The article examines five structural features that determine the nature of these interactions and suggests that there needs to be greater clarity in these relationships. The primary relationship in terms of responsibility and accountability of officers of Parliament should be with Parliament. Reforms are recommended to recognize and to reinforce the primacy of that relationship.

[source] Not all roads lead to Rome,a review of quality of life measurement in adults with diabetesDIABETIC MEDICINE, Issue 4 2009J. Speight Abstract Aims Quality of life (QoL) is recognized widely as an important health outcome in diabetes, where the burden of self-management places great demands on the individual. However, the concept of QoL remains ambiguous and poorly defined. The aim of our review is to clarify the measurement of QoL in terms of conceptualization, terminology and psychometric properties, to review the instruments that have been used most frequently to assess QoL in diabetes research and make recommendations for how to select measures appropriately. Methods A systematic literature search was conducted to identify the ten measures most frequently used to assess QoL in diabetes research (including clinical trials) from 1995 to March 2008. Results Six thousand and eight-five abstracts were identified and screened for instrument names. Of the ten instruments most frequently used to assess ,QoL', only three actually do so [i.e. the generic World Health Organization Quality of Life (WHOQOL) and the diabetes-specific Diabetes Quality of Life (DQOL) and Audit of Diabetes-Dependent Quality of Life (ADDQoL)]. Seven instruments more accurately measure health status [Short-Form 36 (SF-36), EuroQoL 5-Dimension (EQ-5D)], treatment satisfaction [Diabetes Treatment Satisfaction Questionnaire (DTSQ)] and psychological well-being [Beck Depression Inventory (BDI), Hospital Anxiety and Depression Scale (HADS), Well-Being Questionnaire (W-BQ), Problem Areas in Diabetes (PAID)]. Conclusions No single measure can suit every purpose or application but, when measures are selected inappropriately and data misinterpreted, any conclusions drawn are fundamentally flawed. If we value QoL as a therapeutic goal, we must ensure that the instruments we use are both valid and reliable. QoL assessment has the proven potential to identify ways in which treatments can be tailored to reduce the burden of diabetes. With careful consideration, appropriate measures can be selected and truly robust assessments undertaken successfully. [source] Can circle hook use benefit billfishes?FISH AND FISHERIES, Issue 2 2009Joseph E Serafy Abstract We performed a quantitative review to evaluate circle hook use in recreational and commercial hook-and-line fisheries that interact with billfishes (Family: Istiophoridae). Specifically, we scrutinized the findings of 11 recent empirical studies that reported, on a species-specific basis, side-by-side measures of circle vs. J-hook fishing performance: catch, mortality, deep-hooking and bleeding rates. Of the 30 total comparisons extracted from the literature that satisfied our inclusion criteria, 13 indicated significant differences between hook types for the specific metric compared. No study reported significant billfish catch rate differences between hook types. However, when significant differences between hook types were found, higher mortality rates and higher rates of deep-hooking and bleeding were associated with J-hooks relative to circle hooks. We conclude that empirical evidence is sufficient to promote circle hook use in almost all hook-and-line fishery sectors that typically interact with istiophorids. However, billfish conservation benefits will only be realized if fishers use unmodified circle hooks, commit to releasing live fish and take other appropriate measures which maximize post-release survival. While there may be fishing modes where circle hook effects are negative, for billfish conservation, we recommend managers grant exceptions to circle hook use only when experimental results support such a practice. [source] APPLIED ISSUES: Size-dependent mortality of migratory silver eels at a hydropower plant, and implications for escapement to the seaFRESHWATER BIOLOGY, Issue 10 2010O. CALLES Summary 1.,The European eel population has decreased drastically during recent decades, and new EU-legislation calls for measures to change this negative trend. This decline has been attributed to a number of factors, including habitat fragmentation by structural barriers that prevent eels moving between freshwater and the sea. The success of downstream migrating adult silver eels migrating past a hydroelectric plant (HEP) in Sweden was examined by radio-telemetry, and the results were considered in a historical context by analysing catch data from the river for 1957,2006. 2.,The choice of routes and passage success were quantified for three treatment groups and one control group of silver eels. The first treatment, the reservoir group (n = 50), was released into the reservoir upstream of the HEP, and these fish could proceed downstream by passing through the HEP (20 mm rack and turbines) or by entering the spill gates into the former channel, bypassing the HEP. The second treatment group (inside rack, n = 15) was released downstream of the 20-mm rack and had to pass through the turbines to continue migration to the sea. The third treatment group consisted of dead radio-tagged eels (n = 6) that were released into the turbines to study the extent of drifting by dead individuals. Finally, the control group (n = 50) was released downstream of the HEP to test for effects of confounding factors. 3.,Most live individuals displayed migratory behaviour and continued to proceed downstream after release. Only 8% of the fish released in the reservoir or downstream of the HEP (control) did not migrate. The probability of reaching the next HEP, 24 km further downstream, was high for the control group (96%) and the reservoir-released individuals that passed the HEP via the spill gates and the former channel (83%). Survival was low and size-dependent for the individuals that passed the turbines (40%) and even lower for the individuals that had to pass through the rack and the turbines (26%). The overall passage success for eels released in the reservoir was 30%, including both routes. 4.,Annual catch data from 1957 to 2006 showed that the number of eels in the River Ätran has decreased. Despite this decrease, escapement biomass has remained unchanged, because of the fact that the mean size of eels has doubled. Passage data from 2007 show that changes in size and abundance have resulted in a reduction of relative escapement to the sea to values that are 21,24% of what they were in 1957,66. However, this low level of escapement could potentially be rectified if appropriate measures facilitating HEP passage are successfully implemented, since the potential escapement biomass in the river, owing to the large size of the eels, has changed little since the 1950s. [source] Road traffic accidents and the elderlyGERIATRICS & GERONTOLOGY INTERNATIONAL, Issue 3 2009Suzan Abou-Raya Aim: To identify and evaluate the causes and characteristics of road traffic accidents (RTA) and to analyze injury patterns in elderly road traffic victims in order to apply appropriate measures for the prevention of RTA in the elderly. Methods: Two hundred and fifty-eight elderly road traffic victims admitted to the Emergency and Traumatology Departments of our institution were enrolled. Complete data about the circumstances surrounding the accident, mechanism of injury, specific injury, comorbid conditions and drug history were recorded. All subjects underwent a physical and mental function examination. Results: The majority of road traffic victims were pedestrians. Most elderly pedestrian accidents were due to falls. Accidents by elderly car drivers occurred frequently at intersections. Craniocerebral and extremity injuries formed the majority of the injuries in pedestrian and cyclist victims whereas chest injuries were commoner in car accident victims. Medical problems and medication usage was common among RTA victims. Conclusion: The fragility of elderly car occupants and pedestrians should be taken into consideration and strategies aimed at the road-user safety including periodic medical screening, improvement of road structure and facilities, and the improved design of motor vehicles should be implemented. [source] Optimal Policy for Financial Market Liberalizations: Decentralization and Capital Flow ReversalsGERMAN ECONOMIC REVIEW, Issue 1 2000Theo S. Eicher Financial market liberalizations are an integral part of economic development. While initial booms in investment and output are commonly seen as signs of successful deregulation, they often reverse at a later stage as international capital flows turn negative and economic growth slows markedly. Such reversals of fortunes have commonly been attributed to incorrect policies that supposedly followed the initial, appropriate measures. It is unclear, however, if capital flow reversals are actually the result of policy reversals, or if they occur as part of the normal transition when financial liberalization is accompanied by a single suboptimal policy. The later hypothesis has not been explored in the theoretical literature We construct a general equilibrium growth model of a small open economy, in which capital flow reversals are the result of a single, suboptimal policy imposed at the beginning of the financial liberalization. We show how improper taxation of foreign borrowing initially leads to strong growth fuelled by an investment boom and foreign borrowing. Still along the transition, however, the model predicts that capital flows must reverse endogenously at a later stage, as the debt burden rises and the country-specific risk premium increases. Our data on the Latin American and East Asian countries provide strong support for our hypothesis. [source] Endodontic teaching in Philippine dental schoolsINTERNATIONAL ENDODONTIC JOURNAL, Issue 5 2000E. V. Cruz Abstract Aim The aim of this study was to evaluate the pattern of undergraduate endodontic teaching in Philippine dental schools. Methodology Data were gathered by sending questionnaires to the deans of the 23 dental schools in the country to determine details of the teaching of root canal treatment in permanent teeth. The covering letter requested that endodontic staff complete the questionnaire. Results Twenty of 23 dental schools returned completed questionnaires. Similarities were observed in the timing of undergraduate endodontic teaching, working length determination, and root canal preparation technique. Irrigating fluids recommended included one or a combination of the following: sodium hypochlorite, hydrogen peroxide, distilled water and EDTA. The root canal medicaments popularly employed were CMCP and eugenol. Most schools used slow-setting zinc oxide eugenol cement as sealer. Differences between schools were noted in the laboratory component of the course. The time allotted for the laboratory exercises, as well as the number of teeth used, differed greatly between each school. An inadequate tutor to student ratio was noted in the majority of schools. Teaching aids were limited and, in most instances, produced by faculty members. Most faculty members teaching endodontics had no specialist training. Conclusion The results of this study have demonstrated that there is a need to review endodontic teaching in the majority of the Philippine dental schools to ensure that the course content and curriculum employed by all schools meet specified standards and that appropriate measures should be considered to enhance the learning experience of students.

The SIRG Parents and Parenting with Intellectual Disabilities membership includes scholars from a number of countries including the United States, Canada, England, Germany, The Netherlands, Sweden, Denmark, Iceland, Japan, Australia and New Zealand. These scholars come from a range of academic and professional disciplines, including sociology, psychology, education, nursing, social work and occupational therapy. Method, This position paper developed by the Parenting SIRG brings into sharp relief the UN Convention on the Rights of Persons with Disabilities adopted by the General Assembly in December 2006. The convention affirms the right of persons with disabilities to marry and found a family (Article 23, (1)(a)). Further, states parties are bound to ,take effective action and appropriate measures to eliminate discrimination against persons with disabilities in all matters relating to marriage, family, parenthood and relationships,' (Article 23 (1)), and ,,render appropriate assistance to persons with disabilities in the performance of their child-rearing responsibilities' (Article 23 (2)). Results, This position paper synthesizes messages from research about the challenges that parents labelled with intellectual disability face, and how they can be assisted in their parenting role.

Tahbaz Abstract Objectives, The study's objective was to audit current diet and disease management in a community-based sample of people with type 1 diabetes. Methods, The study involved adults with type 1 diabetes and control subjects. Reported amounts of dietary intake were collected. Indices of diabetes control were determined by standard methods. Quality of life of both groups was assessed with appropriate measures. Results were compared between two groups. Results, Mean HbA1c concentration was 8.5% (SD 2.21%) for women with diabetes and 8.6% (SD 1.91%) for men. There was no significant difference between the diabetic and control subjects in self-reported energy intake and macronutrient intake, with the exception that the contribution of saturated fatty acid to energy intake was higher in male controls than in male diabetics. There was no association between dietary intakes and glycemic control in diabetic subjects. Anthropometric measurements, blood pressure and plasma lipids in patients were within normal range and not significantly different from the controls. Plasma fibrinogen concentration was higher in patients. Diabetic subjects did not have a diminished quality of life. Conclusions, Dietary management in these patients was generally focused on controlling carbohydrate intake. Most had suboptimal diabetes control. [source] A Review of Outcome Measures in Early Childhood ProgramsJOURNAL OF POLICY AND PRACTICE IN INTELLECTUAL DISABILITIES, Issue 4 2006Hasheem Mannan Abstract, The authors undertook a review of measures available for assessing outcomes of early childhood services for children with disabilities and their families. With principles of family-centered practice mandating the inclusion of both family and child outcome measures in effective evaluation plans, the review examined measures with established psychometric properties for (a) documenting the effectiveness of partnerships with families, and (b) documenting the effectiveness of services and supports for families. Constructs and their associated measures related to partnerships include satisfaction with the overall program and empowerment. The constructs for outcomes of supports and services include social support, parenting, and family quality of life. The authors reviewed measures for each of the five constructs. They note that the selection of appropriate measures to assess the outcomes of family support and services depends on the specific configuration of support services provided by the program and that each program may have to be explicit about the outcomes it wants to impact and therefore measure. [source] Determination and removal of impurities in 2-D LC-MS of peptidesJOURNAL OF SEPARATION SCIENCE, JSS, Issue 4 2006Albena Mihailova Abstract Problems occurring during operation of a 2-D LC-MS system for separation and identification of neuropeptides, such as contamination of the used salts and column bleed, are described. When using polysulfoethyl aspartamide, which is widely used as a strong cation exchange stationary phase in the first dimension, interfering peaks were observed in the second-dimension reversed-phase chromatograms. The observed peaks, found to be caused by column bleeding, had abundance above the threshold value and influenced the quality of the analyses. The origin of the peaks was verified and appropriate measures are proposed. Additionally, peaks caused by polyethylene glycols (PEGs), covering approximately 5 min of feasible chromatographic time in every fraction, were observed. The commercial ammonium formate salts used to prepare the first-dimension mobile phase were found to contain PEG impurities, and in subsequent work the salt solutions were prepared from formic acid and ammonia to avoid any additional contaminations.

This approach can be effective in order to discover cost and risk factors that are hidden at more aggregated levels. However, it is not trivial to derive appropriate measures of individual changes for specific measurement goals. The purpose of this review is to improve change-based studies by (1) summarizing how attributes of changes have been measured to reach specific study goals and (2) describing current achievements and challenges, leading to a guide for future change-based studies. Thirty-four papers conformed to the inclusion criteria. Forty-three attributes of changes were identified, and classified according to a conceptual model developed for the purpose of this classification. The goal of each study was to either characterize the evolution process, to assess causal factors of cost and risk, or to predict costs and risks. Effective accumulation of knowledge across change-based studies requires precise definitions of attributes and measures of change. We recommend that new change-based studies base such definitions on the proposed conceptual model. Copyright © 2009 John Wiley & Sons, Ltd. [source] Predisposing factors to phlebitis in patients with peripheral intravenous catheters: A descriptive studyJOURNAL OF THE AMERICAN ACADEMY OF NURSE PRACTITIONERS, Issue 4 2008Esin Uslusoy BSN, MS (Research Assistant) Abstract Purpose: The purpose of this study was to investigate the predisposing factors in the development of phlebitis in peripheral intravenous (IV) catheterization sites in patients treated with a variety of IV infusion solutions and drugs. Data sources: Systematic observation of 568 IV sites inserted for fluid infusion and drug administration in 355 patients in the Department of General Surgery of a University Hospital in Turkey. A data collection tool was based on standards established by the Infusion Nurses Society. Patients' infusion sites were monitored every 24 h during treatment and for 48 h after discontinuation of the IV. Conclusions: In contrast to the usual findings in the literature, the authors found that infusion through an infusion pump and insertion of catheters in the veins around the elbow increased the risk of phlebitis. Also, the number of times infusions were started led to an increased rate of phlebitis. However, conflicting results were obtained about the relation between phlebitis, gender, and catheter size. Implications for practice: Phlebitis causes sepsis, pain, additional diagnostic investigations, and treatments, and may lead to increased duration of hospitalization, patient's stress level, and financial burden, as well as increasing staff workload. Advanced practice nurses need to be aware of the factors that increase the likelihood of phlebitis and take appropriate measures to prevent it. [source] Sexual and gender-related harassment in medical education and research training: results from a Swedish surveyMEDICAL EDUCATION, Issue 1 2003Charlotte Larsson Objective, The aims of this study were to establish the level of perceived sexual and gender-related harassment in undergraduate and doctoral studies, in which environment the events occurred, which categories of persons had committed the harassment, and other aspects of sexual harassment at the Faculty of Medicine, Gothenburg University. Methods, A questionnaire was distributed to all registered male and female undergraduate students (n= 605) and doctoral students (n=743) by mail to their home addresses. Results, The response rate was 62% (840/1348). Of the total study population, 59% (495/840) of respondents reported at least one experience of derogatory jokes and comments, 54% (454/840) of respondents reported at least one experience of gender-related discrimination, and 22% (187/840) of respondents reported at least one incident of sexual harassment. More severe types of sexual harassment were reported by 9% (79/840) of respondents. Women, and especially undergraduate women, were more often exposed to all kinds of harassment than were men. Lecturers/professors, doctors and co-students were the categories most often identified as the harassers. The harassment mostly occurred during lectures, clinical work and coffee breaks. The most common types of self-perceived mistreatment were derogatory jokes and comments. Conclusion, This survey shows that sexual harassment happens to both men and women, although it is more commonly experienced by female undergraduate and doctoral students, and that it occurs in both the university and hospital environments. Universities should develop action plans to prevent such events. Students and teachers should be well informed about appropriate measures to take in situations where harassment is known or suspected to occur. [source] The Assessment of Cognitive Performance in Children: Considerations for Detecting Nutritional InfluencesNUTRITION REVIEWS, Issue 12 2003Donna Hughes MPsychClin The accurate assessment of cognitive performance in children is critical for detecting the effects of micronutrient deficiency or supplementation on the developing brain and its functions. Relatively little attention has been paid to the selection of culturally appropriate measures that are sensitive enough to detect the subtle cognitive changes that could be expected following nutritional intervention. Normal brain development and the emergence of cognitive abilities throughout infancy and childhood is discussed in this paper, followed by a description of the more pertinent and sensitive neuropsychological tests that can be used to assess cognitive performance and investigate the effects of micronutrient deficiency and supplementation on cognitive development among children in a variety of cultures. [source] Comparison of herbicide regimes and the associated potential environmental effects of glyphosate-resistant crops versus what they replace in EuropePEST MANAGEMENT SCIENCE (FORMERLY: PESTICIDE SCIENCE), Issue 4 2008Gijs A Kleter Abstract While cultivation of transgenic crops takes place in seven of the EU member states, this constitutes a relatively limited part of the total acreage planted to these crops worldwide. The only glyphosate-resistant (GR) crop grown commercially until recently has been soybean in Romania. In addition, large-scale experimental European data exist for GR sugar and fodder beets, and, to a lesser extent, GR oilseed rape. These GR crops are likely to have an impact both on the use of herbicides and on the environmental impact of the latter. From the data on these GR crops, it appears that quantities of herbicides applied to GR beets are decreased while those on GR soybean are slightly increased compared with their conventional counterparts. Depending on the parameters used for prediction or measurement of environmental impacts of GR crops, generally similar or less negative impacts were observed compared with conventional crops. Favourable environmental effects of the glyphosate-containing herbicide regimes on GR crops appear feasible, provided appropriate measures for maintaining biodiversity and prevention of volunteers and gene flow are applied.
