    The mathematical models and computer program comprising the SPP Dynamic Simulation are described. The SPP Dynamic Simulation is a computerized model representing the time-varying performance characteristics of the SPP. The model incorporates all the principal components of the pilot plant. Time-dependent direct normal solar insulation, as corrupted by simulated cloud passages, is transformed into absorbed radiant power by actions of the heliostat field and enclosed receiver cavity. The absorbed power then drives the steam generator model to produce superheated steam for the turbine and/or thermal storage subsystems. The thermal storage subsystem can, in turn, also produce steam for the turbine. The turbine using the steam flow energy produces the mechanical shaft power necessary for the generator to convert it to electrical power. This electrical power is subsequently transmitted to a transmission grid system. Exhaust steam from the turbine is condensed, reheated, deaerated, and pressurized by pumps for return as feedwater to the thermal storage and/or steam generator. A master control/instrumentation system is utilized to coordinate the various plant operations. The master controller reacts to plant operator demands and control settings to effect the desired output response. The SPP Dynamic Simulation Computer program is written in FORTRAN language. Various input options (e.g., insolation values, load demands, initial pressures/temperatures/flows) are permitted. Plant performance may be monitored via computer printout or computer generated plots. The remainder of this document describes the detailed pilot plant dynamic model, the basis for this simulation, and the utilization of this simulation to obtain analytical plant performance results.

    2017-01-01

    Background and aims The nine-item Internet Gaming Disorder Scale – Short Form (IGDS-SF9) is brief and effective to evaluate Internet Gaming Disorder (IGD) severity. Although its scores show promising psychometric properties, less is known about whether different groups of gamers interpret the items similarly. This study aimed to verify the construct validity of the Persian IGDS-SF9 and examine the scores in relation to gender and hours spent online gaming among 2,363 Iranian adolescents. Methods Confirmatory factor analysis (CFA) and Rasch analysis were used to examine the construct validity of the IGDS-SF9. The effects of gender and time spent online gaming per week were investigated by multigroup CFA and Rasch differential item functioning (DIF). Results The unidimensionality of the IGDS-SF9 was supported in both CFA and Rasch. However, Item 4 (fail to control or cease gaming activities) displayed DIF (DIF contrast = 0.55) slightly over the recommended cutoff in Rasch but was invariant in multigroup CFA across gender. Items 4 (DIF contrast = −0.67) and 9 (jeopardize or lose an important thing because of gaming activity; DIF contrast = 0.61) displayed DIF in Rasch and were non-invariant in multigroup CFA across time spent online gaming. Conclusions Given the Persian IGDS-SF9 was unidimensional, it is concluded that the instrument can be used to assess IGD severity. However, users of the instrument are cautioned concerning the comparisons of the sum scores of the IGDS-SF9 across gender and across adolescents spending different amounts of time online gaming.

    2017-01-01

    This study examines the long-term impact of the faculty development programs on the multiple choice question (MCQ) items' quality leading to study its effect on the students' overall competency level during their yearly academic assessment. A series of longitudinal highly constructed faculty development workshops were conducted to improve the quality of the MCQs items writing skills. A total of 2207 MCQs were constructed by 58 participants for the assessment of 882 students' cognitive competency level during the academic years 2012-2015. The MCQs were analyzed for the difficulty index (P-value), discriminating index (DI), presence/absence of item writing flaws (IWFs), and non-functioning distractors (NFDs), Bloom's taxonomy cognitive levels, test reliability, and the rate of students' scoring. Significant improvement in the difficulty index and DI were noticed during each successive academic year. Easy and poor discriminating questions, NFDs and IWFs were decreased significantly, whereas distractor efficiency (DE) mean score and high cognitive level (K2) questions were increased substantially during the each successive academic year. Improved MCQs' quality leaded to increased competency level of the borderline students. Overall, the longitudinal faculty development workshops help in improving the quality of the MCQs items writing skills of the faculty that leads to students' high competency levels.

    The aim of this study was to assess the utility of long term faculty development programs (FDPs) in order to improve the quality of multiple choice questions (MCQs) items' writing. This was a quasi-experimental study, conducted with newly joined faculty members. The MCQ items were analyzed for difficulty index, discriminating index, reliability, Bloom's cognitive levels, item writing flaws (IWFs) and MCQs' nonfunctioning distractors (NFDs) based test courses of respiratory, cardiovascular and renal blocks. Significant improvement was found in the difficulty index values of pre- to post-training (p = 0.003). MCQs with moderate difficulty and higher discrimination were found to be more in the post-training tests in all three courses. Easy questions were decreased from 36.7 to 22.5%. Significant improvement was also reported in the discriminating indices from 92.1 to 95.4% after training (p = 0.132). More number of higher cognitive level of Bloom's taxonomy was reported in the post-training test items (pwriting.

    Science.gov (United States)

    Kumagai, Ryuichi

    2012-04-01

    We propose a new method, called index K, to estimate the degree of differential item functioning (DIF) on a questionnaire or test taken by multiple groups. A computer program (EasyDIF) was developed to calculate index K. In developing the program, the three following concerns were paramount: (a) the program is applicable when there are more than three groups to be analyzed, (b) it is able to accommodate polytomous items, such as a Likert scale, and (c) details of DIF can be presented in a graph. In simulations and using Big Five scale data, the performance of index K was comparable to the Mantel-Haenszel method and to the Poly-SIBTEST. It is necessary to repeat the calculations to obtain index K. However, because EasyDIF has a graphical user interface, it was intuitively easy to use. Therefore, the results were easier to obtain using EasyDIF.

    Full Text Available Objectives: Students who perceived their learning environment positively are more likely to develop effective learning strategies, and adopt a deep learning approach. Currently, there is no validated instrument for measuring the educational environment of educational programs on respiratory care (RC. The aim of this study was to develop an instrument to measure students′ perception of the RC educational environment. Materials and Methods: Based on the literature review and an assessment of content validity by multiple focus groups of RC educationalists, potential items of the instrument relevant to RC educational environment construct were generated by the research group. The initial 71 item questionnaire was then field-tested on all students from the 3 RC programs in Saudi Arabia and was subjected to multi-trait scaling analysis. Cronbach′s alpha was used to assess internal consistency reliabilities. Results: Two hundred and twelve students (100% completed the survey. The initial instrument of 71 items was reduced to 65 across 5 scales. Convergent and discriminant validity assessment demonstrated that the majority of items correlated more highly with their intended scale than a competing one. Cronbach′s alpha exceeded the standard criterion of >0.70 in all scales except one. There was no floor or ceiling effect for scale or overall score. Conclusions: This instrument is the first assessment tool developed to measure the RC educational environment. There was evidence of its good feasibility, validity, and reliability. This first validation of the instrument supports its use by RC students to evaluate educational environment.

  13. Multi-item fuzzy inventory problem with space constraint via geometric programming method

    Directory of Open Access Journals (Sweden)

    Mandal Kumar Nirmal

    2006-01-01

    Full Text Available In this paper, a multi-item inventory model with space constraint is developed in both crisp and fuzzy environment. A profit maximization inventory model is proposed here to determine the optimal values of demands and order levels of a product. Selling price and unit price are assumed to be demand-dependent and holding and set-up costs sock dependent. Total profit and warehouse space are considered to be vague and imprecise. The impreciseness in the above objective and constraint goals has been expressed by fuzzy linear membership functions. The problem is then solved using modified geometric programming method. Sensitivity analysis is also presented here.

    2015-06-01

    Full Text Available Background and methods: Fuzzy decision-making approach is allowed in geometric programming for a single item EOQ model with dynamic ordering cost and demand-dependent unit cost. The setup cost varies with the quantity produced/purchased and the modification of objective function with storage area in the presence of imprecisely estimated parameters are investigated.  It incorporates all concepts of a fuzzy arithmetic approach, the quantity ordered, and demand per unit compares both fuzzy geometric programming technique and other models for linear membership functions.  Results and conclusions: Investigation of the properties of an optimal solution allows developing an algorithm whose validity is illustrated through an example problem and the results discu ssed. Sensitivity analysis of the optimal solution is also studied with respect to changes in different parameter values.  

  16. Optimising the selection of food items for FFQs using Mixed Integer Linear Programming.

    Gerdessen, Johanna C; Souverein, Olga W; van 't Veer, Pieter; de Vries, Jeanne Hm

    2015-01-01

    To support the selection of food items for FFQs in such a way that the amount of information on all relevant nutrients is maximised while the food list is as short as possible. Selection of the most informative food items to be included in FFQs was modelled as a Mixed Integer Linear Programming (MILP) model. The methodology was demonstrated for an FFQ with interest in energy, total protein, total fat, saturated fat, monounsaturated fat, polyunsaturated fat, total carbohydrates, mono- and disaccharides, dietary fibre and potassium. The food lists generated by the MILP model have good performance in terms of length, coverage and R 2 (explained variance) of all nutrients. MILP-generated food lists were 32-40 % shorter than a benchmark food list, whereas their quality in terms of R 2 was similar to that of the benchmark. The results suggest that the MILP model makes the selection process faster, more standardised and transparent, and is especially helpful in coping with multiple nutrients. The complexity of the method does not increase with increasing number of nutrients. The generated food lists appear either shorter or provide more information than a food list generated without the MILP model.

    Evidence indicates that restaurant-based interventions have the potential to promote healthier purchasing and improve the nutrients consumed. This study adds to this body of research by reporting the results of a trial focused on promoting the sale of healthy child menu items in independently owned restaurants. Eight pair-matched restaurants that met the eligibility criteria were randomized to a menu-only versus a menu-plus intervention condition. Both of the conditions implemented new healthy child menu items and received support for implementation for eight weeks. The menu-plus condition also conducted a marketing campaign involving employee trainings and promotional materials. Process evaluation data captured intervention implementation. Sales of new and existing child menu items were tracked for 16 weeks. Results indicated that the interventions were implemented with moderate to high fidelity depending on the component. Sales of new healthy child menu items occurred immediately, but decreased during the post-intervention period in both conditions. Sales of existing child menu items demonstrated a time by condition effect with restaurants in the menu-plus condition observing significant decreases and menu-only restaurants observing significant increases in sales of existing child menu items. Additional efforts are needed to inform sustainable methods for improving access to healthy foods and beverages in restaurants.

    Science.gov (United States)

    Moody, D.W.; Maddock, Thomas; Karlinger, M.R.; Lloyd, J.J.

    1973-01-01

    Because the use of the Mathematical Programming System -Extended (MPSX) to solve large linear and mixed integer programs requires the preparation of many input data cards, a matrix generator program to produce the MPSX input data from a much more limited set of data may expedite the use of the mixed integer programming optimization technique. The Model Definition and Control Program (MODCQP) is intended to assist a planner in preparing MPSX input data for the Puerto Rico Water Resources Planning Model. The model utilizes a mixed-integer mathematical program to identify a minimum present cost set of water resources projects (diversions, reservoirs, ground-water fields, desalinization plants, water treatment plants, and inter-basin transfers of water) which will meet a set of future water demands and to determine their sequence of construction. While MODCOP was specifically written to generate MPSX input data for the planning model described in this report, the program can be easily modified to reflect changes in the model's mathematical structure.

  3. Assessment of the quality and applicability of an e-portfolio capstone assessment item within a bachelor of midwifery program.

    Science.gov (United States)

    Baird, Kathleen; Gamble, Jenny; Sidebotham, Mary

    2016-09-01

    Education programs leading to professional licencing need to ensure assessments throughout the program are constructively aligned and mapped to the specific professional expectations. Within the final year of an undergraduate degree, a student is required to transform and prepare for professional practice. Establishing assessment items that are authentic and able to reflect this transformation is a challenge for universities. This paper both describes the considerations around the design of a capstone assessment and evaluates, from an academics perspective, the quality and applicability of an e-portfolio as a capstone assessment item for undergraduate courses leading to a professional qualification. The e-portfolio was seen to meet nine quality indicators for assessment. Academics evaluated the e-portfolio as an authentic assessment item that would engage the students and provide them with a platform for ongoing professional development and lifelong learning. The processes of reflection on strengths, weaknesses, opportunities and threats, comparison of clinical experiences with national statistics, preparation of professional philosophy and development of a curriculum vitae, whilst recognised as comprehensive and challenging were seen as highly valuable to the student transforming into the profession.

    Science.gov (United States)

    Heinemann, L; Heise, T; Kamper, K

    1993-04-01

    Glucose clamp experiments are often performed by means of a Biostator. Due to the fact that this device does not provide data storage, data analysis has to be done manually or data must be fed into the computer. In order to enhance the efficacy of data analysis and to avoid time consuming work, a data acquisition program (Biotrans) has been developed which allows data transfer from the Biostator into an IBM compatible computer. After a complex analysis of incoming data, Biotrans provides on-line data storage and display features (blood glucose concentrations and glucose infusion rate). Off-line analysis of the stored data is accomplished by conventional spread sheet programs, thus permitting complex data calculations and graphic presentation. In more than 300 glucose clamp experiments performed within the last three years Biotrans was an important tool providing data storage capabilities, better control of ongoing events during an experiment and rapid and reliable data analysis immediately after completion of individual experiments.

    Shega, Joseph W; Levin, Amy; Hougham, Gavin W; Cox-Hayley, Deon; Luchins, Daniel; Hanrahan, Patricia; Stocking, Carol; Sachs, Greg A

    2003-04-01

    Hospice is the standard method for providing quality end-of-life care in the United States. However, studies reveal that persons with dementia are infrequently referred to hospice, that barriers exist to increasing hospice utilization in this population, and that patients with dementia would benefit from hospice or hospice-like services earlier in the disease course. The Palliative Excellence in Alzheimer Care Efforts (PEACE) program responds to these deficiencies, striving to improve end-of-life care of persons with dementia and to integrate palliative care into the primary care of patients with dementia throughout the course of the illness. The PEACE program is a disease management model for dementia that incorporates advance planning, patient-centered care, family support, and a palliative care focus from the diagnosis of dementia through its terminal stages. PEACE is coordinated through the primary care geriatrics practice of the University of Chicago. Patients and caregivers are interviewed every 6 months for 2 years, and a postdeath interview is conducted with caregivers. These interviews assess care domains important for the optimal care of persons with dementia and their caregivers. A nurse coordinator reviews interviews and provides feedback to physicians, facilitating enhanced individual care and continuous quality improvement for the practice. Initial feedback suggests patients have adequate pain control, satisfaction with quality of care, appropriate attention to prior stated wishes, and death occurring in the patient's location of choice. Families voiced similar high marks regarding quality of care. This program demonstrates an innovative model of providing quality palliative care for dementia patients and their caregivers.

    On the Hanford Site, many surplus facilities exist (including buildings, stacks, tanks, cribs, burial grounds, and septic systems) that are scheduled to be decommissioned. Many of these facilities contain large inventories of radionuclides, which present potential radiological hazards on and off the Hanford Site. Some structures with limited structural deterioration present potential radiological and industrial safety hazards to personnel. Because of the condition of these facilities, a systematic surveillance and maintenance program is performed to identify and correct potential hazards to personnel and the environment until eventual decommissioning operations are completed.

    The U.S. Department of Energy (DOE) currently owns two AXYS WindSentinel buoys that collect a comprehensive set of meteorological and oceanographic data to support resource characterization for wind energy offshore. The two buoys were delivered to DOE’s Pacific Northwest National Laboratory (PNNL) in September, 2014. After acceptance testing and initial performance testing and evaluation at PNNL’s Marine Sciences Laboratory in Sequim, Washington, the buoys have been deployed off the U.S. East Coast. One buoy was deployed approximately 42 km east of Virginia Beach, Virginia from December, 2014 through June, 2016. The second buoy was deployed approximately 5 km off Atlantic City, New Jersey in November, 2015. Data from the buoys are available to the public. Interested parties can create an account and log in to http://offshoreweb.pnnl.gov. In response to a number of inquiries and unsolicited proposals, DOE’s Wind Energy Technologies Office is implementing a program, to be managed by PNNL, to lend the buoys to qualified parties for the purpose of acquiring wind resource characterization data in areas of interest for offshore wind energy development. This document describes the buoys, the scope of the loans, the process of how borrowers will be selected, and the schedule for implementation of this program, including completing current deployments.

  18. Faculty Descriptions of Simulation Debriefing in Traditional Baccalaureate Nursing Programs.

    Science.gov (United States)

    Waznonis, Annette R

    A study was conducted to describe simulation debriefing practices of faculty in accredited, traditional, baccalaureate nursing programs in the United States. Best debriefing practices include debriefing by a competent facilitator in a safe environment using a structured framework. Yet, structured frameworks and evaluation of debriefing are lacking in nursing education. This article reports the interview findings from the qualitative component of a large-scale mixed-methods study. Twenty-three full-time faculty members with an average of 6 years of simulation debriefing experience participated in interviews. Three themes emerged with subthemes: a) having the student's best interest at heart, b) getting over the emotional hurdle, and c) intentional debriefing evolves into learning. Gaps were found in faculty development, use of a structured framework, and evaluation. Research is warranted on use of video, postdebriefing assignments, cofacilitation, and debriefing effectiveness.

    2010-01-01

    The present article illustrates how the National Household Education Surveys (NHES; U.S. Department of Education, 2009) database might be used to address questions of relevance to researchers who are concerned with literacy development among young children. Following a general description of the NHES database, a study is provided that examines the extent to which parent-reported home literacy activities and child emergent literacy skills differ for children with (a) developmental disabilities versus those who are developing typically, (b) single disability versus multiple disabilities, and (c) speech-language disability only versus other types of disabilities. Four hundred and seventy-eight preschool-age children with disabilities and a typically developing matched sample (based on parent report) were identified in the 2005 administration of the Early Childhood Program Participation (ECPP) Survey in the NHES database. Parent responses to survey items were then compared between groups. After controlling for age and socioeconomic status, no significant differences were found in the frequency of home literacy activities for children with and without disabilities. Parents reported higher levels of emergent literacy skills for typically developing children relative to children with disabilities. These findings suggest the importance of considering the home literacy experiences and emergent literacy skills of young children with disabilities when making clinical recommendations.

  6. Development and Validation of Written Exam Items for the Agricultural Hazardous Occupations Orders (AgHOs) Certification Training Program.

    Research was conducted to develop and validate a pool of exam items that can be used to test the readiness of youth, ages 14-15 years, to be certified under the current federally mandated Agricultural Hazardous Occupations Orders (AgHOs). The AgHOs require training prior to employment in agricultural workplaces that the Secretary of Labor has determined are especially hazardous for youth within the prescribed age range. Under the current provisions of the AgHOs certification process, non-exempt youth seeking employment in agriculture are required to pass a written exam concentrating on safe work practices as partial satisfaction to receive certification of eligibility for employment to perform certain tasks. However, the regulations provide little guidance concerning the format of the exam, subject matter to be covered, degree of difficulty, or minimum passing score. As part of the USDA-sponsored Hazardous Occupations Safety Training in Agriculture (HOSTA) initiative, efforts have been made to develop consistent and evidence-based testing methods for disseminating the test protocols to instructors. The goal was to expand, enhance, and maintain the reliability of the exam item pool for the AgHOs certification process. Item development was based on the HOSTA-supported Gearing Up for Safety: Production Agriculture Safety Training for Youth curriculum. To ensure adequate item availability, the current item pool was expanded to include a minimum of two test items for each of the 157 cognitive-based core competencies developed as part of the Gearing Up curriculum design process. Administering 70-item exams that were generated from the item pool to 568 youth, ages 13-18 years, provided evidence of item validity. The result was a pool of 367 validated exam items.

    Lawrence Livermore National Laboratory Immobilization Development and Testing organization (LLNL ID and T) is a Participant in the Plutonium Immobilization Project (PIP). The LLNL D and T has lead responsibilities for form characterization and qualification, ceramic form development, process/equipment development with plutonium, and process systems testing and validation for both conversion and immobilization. This work must be performed in accordance with the graded approach of a Quality Assurance (QA) Program. A QA Program has been developed at LLNL to meet the requirements of the DOE/MD Quality Assurance Requirements. The LLNL QA Program consists of a Quality Assurance Program Description (QAPD) and Quality Implementing Procedures. These documents interface and are a subset of the overall PIP QA Program Documents. The PIP QA Program is described in the PIP ID and T QA Plan, PIP QAPD, and QA Procedures. Other Participant Organizations also must document and describe their PIP compliant QA Programs in a QAPD and implementing procedures. The purpose of this LLNL QAPD is to describe the organization, management processes, QA Controls for Grading, functional responsibilities, levels of authority, and interfaces for those managing, performing, and assessing the adequacy of work.

    The failure to simultaneously address two objectives (increasing the average health of the population and reducing health inequalities) may have led to what has been observed in France so far: an overall decrease in mortality and increase in inequality. The Apprendre et Agir pour Réduire les Inégalités Sociales de Santé (AAPRISS) methodology is to analyze and modify interventions that are already underway in terms of their potential impact on health inequalities. It relies on partnership between researchers and actors in the health field, as well as policy makers. In this paper, we describe the program and discuss its feasibility and acceptability. This program is not a single intervention, but a process aiming at assessing and reshaping existing health programs, therefore acting as a kind of meta-intervention. The program develops scientific and methodological support stemming from co-construction methods aimed at increasing equity within the programs. Stakeholders from prevention policy-making and the health care system, as well as researchers, collaborate in defining interventions, monitoring their progress, and choosing indicators, methods and evaluation procedures. The target population is mainly the population of the greater Toulouse area. The steps of the process are described: (1) establishment of AAPRISS governance and partnerships; (2) inclusion of projects; and (3) the projects' process. Many partners have rallied around this program, which has been shown to be feasible and acceptable by partners and health actors. A major challenge is understanding each partner's expectations in terms of temporality of interventions, expected outcomes, assessment methods and indicators. Analyzing the projects has been quite feasible, and some modifications have been implemented in them in order to take inequalities in health into account. © The Author(s) 2015.

    1992-03-01

    WINDOW 4.0 is a publicly available IBM PC compatible computer program developed by the Windows and Daylighting Group at Lawrence Berkeley Laboratory for calculating total window thermal performance indices (e.g. U-values, solar heat gain coefficients, shading coefficients, and visible transmittances). WINDOW 4.0 provides a versatile heat transfer analysis method consistent with the rating procedure developed by the National Fenestration Rating Council (NFRC). The program can be used to design and develop new products, to rate and compare performance characteristics of all types of window products, to assist educators in teaching heat transfer through windows, and to help public officials in developing building energy codes. WINDOW 4.0 is a major revision to WINDOW 3.1 and we strongly urge all users to read this manual before using the program. Users who need professional assistance with the WINDOW 4.0 program or other window performance simulation issues are encouraged to contact one or more of the NFRC-accredited Simulation Laboratories. A list of these accredited simulation professionals is available from the NFRC.

    Family Planning (FP) program in Pakistan has been struggling to achieve the desired indicators. Despite a well-timed initiation of the program in late 50s, fertility decline has been sparingly slow. As a result, rapid population growth is impeding economic development in the country. A high population growth rate, the current fertility rate, a stagnant contraceptive prevalence rate and high unmet need remain challenging targets for population policies and FP programs. To accelerate the pace of FP programs and targets concerned, it is imperative to develop and adopt a holistic approach and strategy for plugging the gaps in various components of the health system: service delivery, information systems, drugs-supplies, technology and logistics, Human Resources (HRs), financing, and governance. Hence, World Health Organization (WHO) health systems building blocks present a practical framework for overall health system strengthening. This descriptive qualitative study, through 23 in-depth interviews, explored the factors related to the health system, and those responsible for a disappointing FP program in Pakistan. Provincial representatives from Population Welfare and Health departments, donor agencies and non-governmental organizations involved with FP programs were included in the study to document the perspective of all stakeholders. Content analysis was done manually to generate nodes, sub-nodes and themes. Performance of FP programs is not satisfactory as shown by the indicators, and these programs have not been able to deliver the desired outcomes. Interviewees agreed that inadequate prioritization given to the FP program by successive governments has led to this situation. There are issues with all health system areas, including governance, strategies, funding, financial management, service delivery systems, HRs, technology and logistic systems, and Management Information System (MIS); these have encumbered the pace of success of the program.

  14. Ocean Margins Program: Closure on the global carbon cycle. Program description

    Energy Technology Data Exchange (ETDEWEB)

    Riches, M.R.

    1994-08-01

    The Department of Energy`s Ocean Margins Program (OMP) is designed to quantitatively assess the importance of coastal ocean systems in the global carbon cycle. Since the beginning of the Industrial Revolution, human energy-related activities have dramatically altered the global carbon cycle, and consequently, this cycle is not presently in a steady-state. To reduce major uncertainties in predicting future global environmental quality, it is imperative to understand the sources and sinks of atmospheric CO{sub 2}, the role of anthropogenic activities in disrupting the natural carbon cycle, and the effects of, and feedbacks between, these activities and the natural carbon cycle. Due to continuously increased loading of nutrients to the margins, which, globally, is related to the rate of human population growth and high population densities in coastal states, biological carbon fixation has been stimulated. Depending on the fate of the fixed carbon, this stimulation has the potential to mitigate the anthropogenically derived Co{sub 2}. Determining the factors that control the magnitude of carbon exchanges between the ocean margins and the atmosphere, and the subsequent fate of this carbon, is crucial to predicting the strength and capacity of the oceans to absorb excess anthropogenic atmospheric CO{sub 2}. The goals of the OMP are to: quantify the ecological and biogeochemical processes and mechanisms that define the cycling, flux, and storage of carbon and other biogenic elements at the land/ocean interface; identify how ocean-margin sources and sinks of carbon change in response to human activities; and determine whether continental shelves are quantitatively significant in removing atmospheric carbon dioxide and isolating it via burial in sediments or export to the interior of the open ocean.

    1995-01-01

    The high-charge-and energy (HZE) transport computer program HZETRN is developed to address the problems of free-space radiation transport and shielding. The HZETRN program is intended specifically for the design engineer who is interested in obtaining fast and accurate dosimetric information for the design and construction of space modules and devices. The program is based on a one-dimensional space-marching formulation of the Boltzmann transport equation with a straight-ahead approximation. The effect of the long-range Coulomb force and electron interaction is treated as a continuous slowing-down process. Atomic (electronic) stopping power coefficients with energies above a few A MeV are calculated by using Bethe's theory including Bragg's rule, Ziegler's shell corrections, and effective charge. Nuclear absorption cross sections are obtained from fits to quantum calculations and total cross sections are obtained with a Ramsauer formalism. Nuclear fragmentation cross sections are calculated with a semiempirical abrasion-ablation fragmentation model. The relation of the final computer code to the Boltzmann equation is discussed in the context of simplifying assumptions. A detailed description of the flow of the computer code, input requirements, sample output, and compatibility requirements for non-VAX platforms are provided.

  18. DrawWing, a program for numerical description of insect wings

    Adam Tofilski

    2004-05-01

    Full Text Available There is usually a pattern of veins on an insect wing. This pattern is species-specific and is used taxonomically. For example, the coordinates of some characteristic points on the wing are used to compare vein patterns. The characteristic points are often vein junctions or vein ends. A tool is presented that enables automatic identification of vein junctions. An image of an insect wing is used to determine the wing outline and veins. The vein skeleton is obtained using a thinning algorithm. Bezier splines are fitted to both the wing outline and the vein skeleton. The splines are saved in an encapsulated postscript file. Another output file in text format contains the coordinates of vein junctions. Both the program and its source code are available under GNU General Public License at [www.cyf-kr.edu.pl/~rotofils/drawwing.html]. The program presented in this paper automatically provides a numerical description of an insect wing. It converts an image of an insect wing to a list of coordinates of vein junctions, and a wing diagram that can be used as an illustration. Coordinates of the vein junctions extracted by the program from wing images were used successfully to discriminate between males of Dolichovespula sylvestris and Dolichovespula saxonica.

    Full Text Available Abstract Background Adolescence is the peak age of onset for mental illness, with half of all people who will ever have a mental illness experiencing their first episode prior to 18 years of age. Early onset of mental illness is a significant predictor for future episodes. However, adolescents and young adults are less likely than the population as a whole to either seek or receive treatment for a mental illness. The knowledge and attitudes of the adults in an adolescent's life may affect whether or not help is sought, and how quickly. In 2007, the Youth Mental Health First Aid Program was launched in Australia with the aim to teach adults, who work with or care for adolescents, the skills needed to recognise the early signs of mental illness, identify potential mental health-related crises, and assist adolescents to get the help they need as early as possible. This paper provides a description of the program, some initial evaluation and an outline of future directions. Methods The program was evaluated in two ways. The first was an uncontrolled trial with 246 adult members of the Australian public, who completed questionnaires immediately before attending the 14 hour course, one month later and six months later. Outcome measures were: recognition of schizophrenia or depression; intention to offer and confidence in offering assistance; stigmatising attitudes; knowledge about adolescent mental health problems and also about the Mental Health First Aid action plan. The second method of evaluation was to track the uptake of the program, including the number of instructors trained across Australia to deliver the course, the number of courses they delivered, and the uptake of the YMHFA Program in other countries. Results The uncontrolled trial found improvements in: recognition of schizophrenia; confidence in offering help; stigmatising attitudes; knowledge about adolescent mental health problems and application of the Mental Health First Aid action

    1999-07-08

    The Plutonium Immobilization Project (PIP) is one of several fissile materials disposition projects managed by the Department of Energy (DOE) Office of Fissile Materials Disposition (OFMD). The PIP is expected to evolve from the current Development and Testing (D and T) effort, to design, to construction, and finally to operations. Overall management and technical management of the D and T effort resides at the Lead Laboratory, Lawrence Livermore National Laboratory (LLNL), through the LLNL Manager, Fissile Materials Disposition Program (FMDP). Day to day project activities are managed by the D and T Technical Project Office (TPO), which reports to the LLNL Manager, FMDP. The D and T TPO consists of the Technical Manager, the TPO Quality Assurance (QA) Program Manager, and TPO Planning and Support Staff. This Quality Assurance Program Description (QAPD) defines the QA policies and controls that will be implemented by these TPO personnel in their management of D and T activities. This QAPD is consistent with and responsive to the Department of Energy Fissile Materials Disposition Program Quality Assurance Requirements Document (FMDP QARD). As the Project and upper level requirement's documents evolve, this QAPD will be updated as necessary to accurately define and describe the QA Program and Management of the PIP. The TPO has a policy that all development and testing activities be planned, performed and assessed in accordance with its customer's requirements, needs and expectations, and with a commitment to excellence and continuous improvement. The TPO QAPD describes implementation requirements which, when completed, will ensure that the project development and testing activities conform to the appropriate QA requirements. For the program to be effective, the TPO QA Program Manager will ensure that each site participating in D and T activities has developed a QAPD, which meets the customer's requirements, and has a designated quality leader in place

    2014-04-01

    To provide a description of a pharmacy residency rotation dedicated to medical writing developed at a tertiary care academic medical center. Contribution to the medical literature is an important component of professional pharmacy practice, and there are many benefits seen by practitioners actively involved in scholarly activities. Residency programs have an opportunity to expand beyond the standard roles of postgraduate pharmacist training but rarely is there formal instruction on medical writing skills or are scholarship opportunities provided to residents. In order to address this deficiency, a residency program may consider the implementation of a formal Medical Writing rotation. This rotation is designed to introduce the resident to medical writing through active discussion on medical writing foundational topics, engage the resident in a collaborative review of a manuscript submitted to a peer-reviewed professional journal, and support the resident in the design and composition of manuscript of publishable quality. A structured Medical Writing rotation during a pharmacy resident's training can help develop the skills necessary to promote scholarly activities and foster resident interest in future pursuit of professional medical writing.

    Faculty continue to observe students struggling as they adapt their study strategies to learn nursing core content. This study described the study habits of Bachelor of Science in Nursing (BSN) students prior to admission to the program. This study used a descriptive qualitative research design. A purposive sample of 19 BSN students (juniors [n=10] and seniors [n=9]) from a 4-year public Midwestern university were included in this study. Two focus group sessions, using a semi-structured interview guide, were conducted in the spring semester of 2013. The four themes which emerged from the analysis of data were: "I just got it," "I had a lot of time then," "I studied alone" mostly, and "…a little struggle with the sciences." The findings suggest the BSN students did not study much or employed poor study strategies during their years completing general education courses. Academic support is needed by students prior to admission to the nursing program so they can learn effective study skills and modify their study habits for easier adaptation to the rigors of nursing education.

    The modern theory of the atomic nucleus results from the merging of the liquid drop model of Niels Bohr and Fritz Kalckar, and of the shell model of Marie Goeppert Meyer and Hans Jensen. The first model contributed the concepts of collective excitations. The second, those of independent-particle motion. The unification of these apparently contradictory views in terms of the particle-vibration and particle-rotation couplings carried out by Aage Bohr and Ben Mottelson has allowed for an ever more complete, accurate and detailed description of nuclear structure. Nuclear field theory (NFT), developed by the Copenhagen-Buenos Aires collaboration, provided a powerful quantal embodiment of this unification. Reactions are not only at the basis of quantum mechanics (statistical interpretation, Max Born), but also the specific tools to probe the atomic nucleus. It is then natural that NFT is being extended to deal with processes which involve the continuum in an intrinsic fashion, so as to be able to treat them on an equal footing with those associated with bound states (structure). As a result, spectroscopic studies of transfer to continuum states could eventually make use of the NFT rules, properly extended to take care of recoil effects. In the present contribution we review the implementation of the NFT program of structure and reactions, setting special emphasis on open problems and outstanding predictions.

    Full Text Available Abstract Colombia has been seriously affected by an internal armed conflict for more than 40 years affecting mainly the civilian population, who is forced to displace, suffers kidnapping, extortion, threats and assassinations. Between 2005 and 2008, Médecins Sans Frontières-France provided psychological care and treatment in the region of Tolima, a strategic place in the armed conflict. The mental health program was based on a short-term multi-faceted treatment developed according to the psychological and psychosomatic needs of the population. Here we describe the population attending during 2005-2008, in both urban and rural settings, as well as the psychological treatment provided during this period and its outcomes. We observed differences between the urban and rural settings in the traumatic events reported, the clinical expression of the disorders, the disorders diagnosed, and their severity. Although the duration of the treatment was limited due to security reasons and access difficulties, patient condition at last visit improved in most of the patients. These descriptive results suggest that further studies should be conducted to examine the role of short-term psychotherapy, adapted specifically to the context, can be a useful tool to provide psychological care to population affected by an armed conflict.

    Children living with cancer must cope with the disease, frequent hospitalizations, aggressive treatments and numerous treatment side effects. Combined, these stressors can lead to adverse biopsychosocial effects. An animal therapy program called "A Magical Dream" was instituted for children hospitalized in pediatric oncology to promote their well-being during hospitalization and facilitate their adaptation to the therapeutic process. The main goal of this preliminary study was to complete a descriptive assessment of the program implementation using Donabedian's quality model. This study aims more specifically at documenting the observed connection between participating in the program, quality of care and satisfaction of participating parents and nurses. A total of 16 parents of children and 12 nurses took part in the implementation study and composed the sample. Data were collected through two self-administered questionnaires intended for parents and one questionnaire for nurses. Evaluating the quality of the animal therapy program includes issues related to user profiles, animal therapy intervention process, organizational structure and client outcomes. It appears that dog-assisted therapy may contribute to alleviate psychological distress in children and parents, facilitate their adaptation to the therapeutic process, and promote their well-being while hospitalized. The goal of a second phase to the project will be to verify the effectiveness of the animal therapy intervention by targeting more specifically children hospitalized with solid tumours. Stemming from a nursing initiative started in 1999, this project aims to promote the well-being of children living with cancer during their hospitalization, reduce their emotional distress and facilitate their adaptation to the therapeutic (psychological, physical and social) process by promoting the emergence of special bonds between children and animals. The animal therapy program at CHUQ allows children accompanied

    This study aimed to develop a job description for healthcare managers of metabolic syndrome management programs using task analysis. Exploratory research was performed by using the Developing a Curriculum method, the Intervention Wheel model, and focus group discussions. Subsequently, we conducted a survey of 215 healthcare workers from 25 community health centers to verify that the job description we created was accurate. We defined the role of healthcare managers. Next, we elucidated the tasks of healthcare managers and performed needs analysis to examine the frequency, importance, and difficulty of each of their duties. Finally, we verified that our job description was accurate. Based on the 8 duties, 30 tasks, and 44 task elements assigned to healthcare managers, we found that the healthcare managers functioned both as team coordinators responsible for providing multidisciplinary health services and nurse specialists providing health promotion services. In terms of importance and difficulty of tasks performed by the healthcare managers, which were measured using a determinant coefficient, the highest-ranked task was planning social marketing (15.4), while the lowest-ranked task was managing human resources (9.9). A job description for healthcare managers may provide basic data essential for the development of a job training program for healthcare managers working in community health promotion programs.

  12. A Comprehensive Mathematical Programming Model for Minimizing Costs in A Multiple-Item Reverse Supply Chain with Sensitivity Analysis

    Directory of Open Access Journals (Sweden)

    Mahmoudi Hoda

    2014-09-01

    Full Text Available These instructions give you guidelines for preparing papers for IFAC conferences. A reverse supply chain is configured by a sequence of elements forming a continuous process to treat return-products until they are properly recovered or disposed. The activities in a reverse supply chain include collection, cleaning, disassembly, test and sorting, storage, transport, and recovery operations. This paper presents a mathematical programming model with the objective of minimizing the total costs of reverse supply chain including transportation, fixed opening, operation, maintenance and remanufacturing costs of centers. The proposed model considers the design of a multi-layer, multi-product reverse supply chain that consists of returning, disassembly, processing, recycling, remanufacturing, materials and distribution centers. This integer linear programming model is solved by using Lingo 9 software and the results are reported. Finally, a sensitivity analysis of the proposed model is also presented.

    Mound, located in Montgomery County, Miamisburg, Ohio, on the east bank of the Great Miami River, was established in 1948 by the Atomic Energy Commission to develop and manufacture explosive devices for the United States Government. Mound occupies 305 acres and at present the facility is operated by EG&G Mound Applied Technologies. It is devoted to research, development, testing and manufacturing of components for nuclear weapons systems under the auspices of the United States Department of Energy (DOE). The complex employs approximately 2,200 people generating an annual payroll in excess of $75 million. Whereas Government sponsors have traditionally placed great emphasis on new technological concepts and manufacturing processes for weapons, unfortunately, such has not been the case in the maintenance of the roadway infrastructure. The roadway system which, for the most part is 40 years old, must be restored to a condition which will ensure smooth transportation of weapon component production, safe access for emergency and fire vehicles and safe ingress and egress for pedestrian personnel. This Facilities Capability Assurance Program (FCAP) project will provide this much needed restoration.

  14. The diffusion of the distance Entomology Master's Degree Program at the University of Nebraska Lincoln: A descriptive case study

    Science.gov (United States)

    Hubbell, Jody M.

    This study explored three selected phases of Rogers' (1995) Diffusion of Innovations Theory to examine the diffusion process of the distance Entomology Master's Degree program at the University of Nebraska, Lincoln. A qualitative descriptive case study approach incorporated semi-structured interviews with individuals involved in one or more of the three stages: Development, Implementation, and Institutionalization. Documents and archival evidence were used to triangulate findings. This research analyzed descriptions of the program as it moved from the Development, to the Implementation, and finally, the Institutionalization stages of diffusion. Each respective stage was examined through open and axial coding. Process coding identified themes common to two or more diffusion stages, and explored the evolution of themes from one diffusion stage to the next. At a time of significant budget constraints, many departments were faced with the possibility of merger or dissolution. The Entomology Master's Degree Program evolved from being an entrepreneurial means to prevent departmental dissolution to eventually being viewed as a model for the development of similar programs across this university and other institutions of higher education. During this evolution, the program was reinvented to meet the broader needs of industry and a global student market. One finding not consistent with Rogers' model was that smaller, rather than larger, departmental size contributed to the success of the program. Within this small department, faculty members were able to share their experiences and knowledge with each other on a regular basis, which promoted greater acceptance of the distance program. How quality and rigor may be defined and measured was a key issue in each respective stage. In this specific case, quality and rigor was initially a comparison of on-campus and distance course content and then moved to program-based assessment and measures of student outcomes such as job

  18. Preparing health professions education leaders worldwide: A description of masters-level programs.

    Science.gov (United States)

    Tekian, Ara; Harris, Ilene

    2012-01-01

    Until 1996, there were only 7 masters-level programs in health professions education (HPE); currently, there are 76 such programs. The purpose of this article is to provide information and perspectives about the available masters programs in HPE worldwide, with a focus on their mission, objectives, content, instructional strategies, format, duration, and cost, as well as the similarities and differences among them. A literature and web search was conducted to develop a complete list of programs that offer a masters degree in HPE or closely related areas. Forty three percent [43% (33)] of these programs are in Europe, 20% (15) in North America, 17% (13) in Asia, 7% (5) in Latin America, 5% (4) in the Middle East, 5% (4) in Australia, and 3% (2) in Africa. The mission of these masters programs is to prepare leaders in HPE or sometimes narrowly focusing on clinical or dental education. The content is addressed in core courses and electives, generally grouped under the following headings: curriculum development, instructional methods/teaching and learning, assessment strategies, program evaluation, research design, and sometimes leadership and management. Medical schools sponsor approximately two-thirds of these programs, and the average duration for completion is 2 years. The vast majority of these programs are offered in English. The commonalities among these programs include focus, content, and educational requirements. The variations are mostly in organization and structure. There is a need to establish criteria and mechanisms for evaluation of these programs. The geographic maldistribution of these programs is a major concern.

    2012-01-01

    Postdoctoral pharmacy industry fellowship programs and the employment of fellowship graduates are described. A list of postgraduate industry fellowships was gathered from the 2009 ASHP Midyear Clinical Meeting. Data regarding program characteristics were collected using the Personnel Placement Service database and program-specific brochures. After data compilation, a standardized survey was sent in January 2010 via e-mail to the point of contact for all programs to confirm the accuracy of the program's characteristics. Only academically affiliated industry fellowship programs were analyzed. Retrospective data were collected regarding the first position of employment for all fellows who graduated from the program between 2005 and 2009 and the position of those same individuals at the time of survey completion. Surveys were sent to 64 postgraduate industry fellowship programs affiliated with a school of pharmacy, 56 (87.5%) of whom responded. The departmental breakdown for positions offered (n = 75) across all academically affiliated industry fellowship programs (including nonresponders) was as follows: medical affairs (38.7%, n = 29), clinical research (32.0%, n = 24), regulatory affairs (9.3%, n = 7), commercial (8.0%, n = 6), health economics and outcomes research (8.0%, n = 6), and pharmacovigilance (4.0%, n = 3). Data from fellows during years 1-5 after completion of the industry fellowship indicated that 90.5% of former fellows remained in the industry (n = 238). The postgraduate industry fellowship programs surveyed indicated that the majority of fellowship graduates continued to hold positions in industry after program completion. The majority of industry fellowships and subsequent job placements occurred in the areas of medical affairs, clinical research, and regulatory affairs.

    Many adolescents have poor mental health literacy, stigmatising attitudes towards people with mental illness, and lack skills in providing optimal Mental Health First Aid to peers. These could be improved with training to facilitate better social support and increase appropriate help-seeking among adolescents with emerging mental health problems. teen Mental Health First Aid (teen MHFA), a new initiative of Mental Health First Aid International, is a 3 × 75 min classroom based training program for students aged 15-18 years. An uncontrolled pilot of the teen MHFA course was undertaken to examine the feasibility of providing the program in Australian secondary schools, to test relevant measures of student knowledge, attitudes and behaviours, and to provide initial evidence of program effects. Across four schools, 988 students received the teen MHFA program. 520 students with a mean age of 16 years completed the baseline questionnaire, 345 completed the post-test and 241 completed the three-month follow-up. Statistically significant improvements were found in mental health literacy, confidence in providing Mental Health First Aid to a peer, help-seeking intentions and student mental health, while stigmatising attitudes significantly reduced. teen MHFA appears to be an effective and feasible program for training high school students in Mental Health First Aid techniques. Further research is required with a randomized controlled design to elucidate the causal role of the program in the changes observed.

  11. Support Method of Model Description Error Detection on a Programming Environment for Multi Agent Simulation

    Science.gov (United States)

    Itakura, Kota; Hatakeyama, Go; Akiyoshi, Masanori; Komoda, Norihisa

    Recently, there are various proposals on tool for multi-agent simulation. However, in such simulation tools, analysts who do not have programming skill spend a lot of time to develop programs because notation of simulation models is not defined sufficiently and programming language is varied on tools. To solve this problem, a programming environment that defines the notation of simulation model has poposed. In this environment, analysts can design simulation with a graph representation and get the program code without writing programs. However, it is difficult to find errors that cause unintended behavior in simulation. Therefore, we propose a support method as a model debugger which helps users to find errors. The debugger generates candidates of errors, using a user's report of unintended behavior based on “typical report patterns”. Candidates of errors are extracted from “tree structure of error-inducing factors” that consists of source patterns of errors. In this paper, we executed experiments that compare time needed for examinees to find errors. Experimental results show the time to find errors by utilizing our model debugger is shortened.

    Anesthesiology residency programs may need new simulation-based programs to prepare residents for the new Objective Structured Clinical Examination (OSCE) component of the American Board of Anesthesiology (ABA) Primary Certification process. The design of such programs may require significant resources, including faculty time, expertise, and funding, as are currently needed for structured oral examination (SOE) preparation. This survey analyzed the current state of US-based anesthesiology residency programs regarding simulation-based educational programming for SOE and OSCE preparation. An online survey was distributed to every anesthesiology residency program director in the United States. The survey included 15 to 46 questions, depending on each respondent's answers. The survey queried current practices and future plans regarding resident preparation specifically for the ABA APPLIED examination, with emphasis on the OSCE. Descriptive statistics were summarized. χ and Fisher exact tests were used to test the differences in proportions across groups. Spearman rank correlation was used to examine the association between ordinal variables. The responding 66 programs (49%) were a representative sample of all anesthesiology residencies (N = 136) in terms of geographical location (χ P = .58). There was a low response rate from small programs that have 12 or fewer clinical anesthesia residents. Ninety-one percent (95% confidence interval [CI], 84%-95%) of responders agreed that it is the responsibility of the program to specifically prepare residents for primary certification, and most agreed that it is important to practice SOEs (94%; 95% CI, 88%-97%) and OSCEs (89%; 95% CI, 83%-94%). While 100% of respondents reported providing mock SOEs, only 31% (95% CI, 24%-40%) of respondents provided mock OSCE experiences. Of those without an OSCE program, 75% (95% CI, 64%-83%) reported plans to start one. The most common reasons for not having an OSCE program already in place

    1991-09-01

    The Office of Civilian Radioactive Waste Management (OCRWM) is executing a plan for improvement of the systems implemented to carry out its responsibilities under the Nuclear Waste Policy Act of 1982 (NWPA). As part of the plan, OCRWM is performing a systems engineering analysis of both the physical system, i.e., the Nuclear Waste Management System (NWMS), and the programmatic functions that must be accomplished to bring the physical system into being. The purpose of the program analysis is to provide a systematic identification and definition of all program functions, functional process flows, and function products necessary and sufficient to provide the physical system. The analysis resulting from this approach provides a basis for development of a comprehensive and integrated set of policies, standard practices, and procedures for the effective and efficient execution of the program. Thus, this analysis will form a basis for revising current OCRWM policies and procedures, or developing new ones is necessary. The primary purposes of this report are as follows: (1) summarizes the major functional processes and process flows that have been developed as a part of the program analysis, and (2) provide an introduction and assistance in understanding the detailed analysis information contained in the three volume report titled The Analysis of the Program to Develop the Nuclear Waste Management System (Woods 1991a).

    The rapid increase in demand for palliative care (PC) services has led to concerns regarding workforce shortages and threats to the resiliency of PC teams. To describe the development, implementation, and evaluation of a regional interdisciplinary training program in PC. Thirty nurse and physician fellows representing 22 health systems across the Chicago region participated in a two-year PC training program. The curriculum was delivered through multiple conferences, self-directed e-learning, and individualized mentoring by expert local faculty (mentors). Fellows shadowed mentors' clinical practices and received guidance on designing, implementing, and evaluating a practice improvement project to address gaps in PC at their institutions. Enduring, interdisciplinary relationships were built at all levels across health care organizations. Fellows made significant increases in knowledge and self-reported confidence in adult and pediatric PC and program development skills and frequency performing these skills. Fellows and mentors reported high satisfaction with the educational program. This interdisciplinary PC training model addressed local workforce issues by increasing the number of clinicians capable of providing PC. Unique features include individualized longitudinal mentoring, interdisciplinary education, on-site project implementation, and local network building. Future research will address the impact of the addition of social work and chaplain trainees to the program. Copyright © 2017 American Academy of Hospice and Palliative Medicine.

    Access to abortion services in the United States is declining. While family physicians are well suited to provide this care, limited training in abortion occurs in family medicine residency programs. This study was designed to describe the structure of currently available training and the experience of residents participating in these programs. E-mail questionnaires were sent to key faculty members and third-year residents in nine programs that have required abortion training. These faculty members and a sample of residents also completed semi-structured interviews. Residency programs varied in the amount of time dedicated to the procedural aspects of abortion training, ranging from 2 to 8 days, and also in non-procedural aspects of training such as values clarification and didactics. Themes that emerged from interviews with residents included the benefit of training with respect to technical skills and continuity of care. In addition, residents valued discussion of the emotional aspects of abortion care and issues relating to performing abortions after graduation from residency. While the details of the curricula vary, residents in programs with required abortion training generally felt positively about their experiences and felt that abortion was an appropriate procedure for family physicians to provide. Residents emphasized the importance of both non-procedural and technical aspects of training.

    Steam Generators (SGs) are a key component of PWR nuclear power plants, maintaining their structural integrity throughout their life time is necessary to allow for long term operation (LTD) of PWR plants. NEI 97-06 provides the fundamental elements to be included in a SG Program. In addiction it describes performance criteria that SG tubes have to meet in order to provide reasonable assurance that the tubes are still able to maintain specific safety function. Hence, it is mandatory for plants with SGs to have defined a SG program consistent with NEI 97-06 and contains the elements which are described by it. This Program must contain some elements such as, Degradation Assessment, inspection and Integrity Assessment, among other. (Author)

    1998-06-01

    The US Department of Energy established a geopressured-geothermal energy program in the mid 1970`s as one response to America`s need to develop alternate energy resources in view of the increasing dependence on imported fossil fuel energy. This program continued for 17 years and approximately two hundred million dollars were expended for various types of research and well testing to thoroughly investigate this alternative energy source.

    To explore experiences with depression and depression treatment among older Hispanic immigrants participating in a collaborative care program of psychotherapy and antidepressant medication. Semi-structured, in-depth interviews were conducted with 14 older Spanish-speaking Hispanic immigrants with major depression who participated in a collaborative care program within a public sector specialty geriatric clinic in Los Angeles, CA. Findings revealed that participants used various idioms to describe their experiences with depression, and that depression had a strong impact on functioning. Other findings indicated that depression was caused by various psychosocial problems, antidepressants were helpful in reducing depression, and that bilingual psychotherapists provided a welcoming and safe environment to express emotions and find solutions to problems. Results revealed participants' experiences with depression and the impact of participating in a collaborative care intervention for depression. Findings from this project should be used to inform future geriatric interventions for older Hispanic immigrants in the USA.

    Professional orchestral musicians risk permanent hearing loss while playing their instruments. Protecting the hearing of these musicians in the workplace is critical to their ongoing ability to play their instruments, but typical workplace hearing conservation measures can have very damaging effects on the product (music) and the musicians' abilities to hear one another sufficiently. To enable effective intervention, orchestras as employers must encourage engagement with hearing protection programs and implement controls while preserving the integrity of the music. To achieve this, typical approaches used in other industries must be redesigned to suit this unique workplace. In response to these challenges, the Queensland Symphony Orchestra (Brisbane, Australia) introduced a comprehensive hearing conservation strategy in 2005 based upon best practice at the time. This strategy-which has been regularly refined-continues to be implemented on a daily basis. This investigation aimed to assess the successes, difficulties, and practical viability of the program. To achieve this a process evaluation was carried out, incorporating archival analyses, player and management focus groups, and an interview with the program's administrator. Results show the program has successfully become integrated into the orchestra's and the musicians' daily operations and significantly contributes to managing the risk of hearing loss in this population. While there is room for improvement in the orchestra's approach-particularly regarding usable personal protective devices and improved education and training, results are encouraging. This study provides a basis for those wishing to implement or evaluate similar paradigms. © The Author 2014.

    One percent of the population of the United States consists of women offenders, who are at-risk for numerous preventable diseases. Since health promotion is not a high priority when women are incarcerated, the author used group education as one way of increasing participants' knowledge and self-efficacy. Results indicated that a group health education program is an excellent way to change participants' knowledge and self-efficacy in a women's prison population.

    The input parameters are presented for a computer program which performs calculations for inviscid isentropic transonic flow over three dimensional airfoils with straight leading edges. The free stream Mach number is restricted only by the isentropic assumption. Weak shock waves are automatically located where they occur in the flow. The finite difference form of the full equation for the velocity potential is solved by the method of relaxation, after the flow exterior to the airfoil is mapped to the upper half plane.

    The purpose of this article is to describe the rationale, clinical processes, and outcomes of an intensive comprehensive aphasia program (ICAP). Seventy-three community-dwelling adults with aphasia completed a residentially based ICAP. Participants received 5 hr of daily 1:1 evidence-based cognitive-linguistically oriented aphasia therapy, supplemented with weekly socially oriented and therapeutic group activities over a 23-day treatment course. Standardized measures of aphasia severity and communicative functioning were obtained at baseline, program entry, program exit, and follow-up. Results were analyzed using a Bayesian latent growth curve model with 2 factors representing (a) the initial level and (b) change over time, respectively, for each outcome measure. Model parameter estimates showed reliable improvement on all outcome measures between the initial and final assessments. Improvement during the treatment interval was greater than change observed across the baseline interval, and gains were maintained at follow-up on all measures. The rationale, clinical processes, and outcomes of a residentially based ICAP have been described. ICAPs differ with respect to treatments delivered, dosing parameters, and outcomes measured. Specifying the defining components of complex interventions, establishing their feasibility, and describing their outcomes are necessary to guide the development of controlled clinical trials.

    Full Text Available Abstract Background Total knee arthroplasty (TKA is a commonly performed surgical procedure in the US. It is important to have a comprehensive inpatient TKA program which maximizes outcomes while minimizing adverse events. The purpose of this study was to describe a TKA program – the Joint Replacement Program (JRP – and report post-surgical outcomes. Methods 74 candidates for a primary TKA were enrolled in the JRP. The JRP was designed to minimize complications and optimize patient-centered outcomes using a team approach including the patient, patient's family, and a multidisciplinary team of health professionals. The JRP consisted of a pre-operative class, standard pathways for medical care, comprehensive peri-operative pain management, aggressive physical therapy (PT, and proactive discharge planning. Measures included functional tests, knee range of motion (ROM, and medical record abstraction of patient demographics, length of stay, discharge disposition, and complications over a 6-month follow-up period. Results All patients achieved medical criteria for hospital discharge. The patients achieved the knee flexion ROM goal of 90° (91.7 ± 5.4°, but did not achieve the knee extension ROM goal of 0° (2.4 ± 2.6°. The length of hospital stay was two days for 53% of the patients, with 39% and 7% discharged in three and four days, respectively. All but three patients were discharged home with functional independence. 68% of these received outpatient physical therapy compared with 32% who received home physical therapy immediately after discharge. Two patients ( Conclusion The comprehensive JRP for TKA was associated with satisfactory clinical outcomes, short lengths of stay, a high percentage of patients discharged home with outpatient PT, and minimal complications. This JRP may represent an efficient, effective and safe protocol for providing care after a TKA.

    Full Text Available Abstract Background The United States Preventive Services Task Force found that effective interventions for extending breastfeeding duration are generally begun during the prenatal period, provide ongoing support for patients and combine information with face-to-face guidance. A 2001 literature review had similar findings but also found that employing a lactation consultant in the clinical setting may increase breastfeeding duration rates. Thus, a program was developed at a family practice office that employed a lactation consultant and followed the American Academy of Pediatrics' "Ten Steps to Support Parents' Choice to Breastfeed Their Baby." Methods The program distributed handouts at each prenatal and well-child visit (up to one year. Using questionnaires, a small audit project evaluated the program's impact on breastfeeding goals, duration, in-hospital exclusivity and maternal perception of success. Mothers completed goal surveys at baseline and post-intervention, usually while waiting for prenatal clinic visits. Duration was assessed by surveys completed during well-infant visits, postal mailings or telephone interviews at breastfeeding cessation, 6 months and 1 year. The outcomes measured were increases in goals, maternal perception of success, duration and in-hospital exclusivity. Results Participants included 33 women: 48% had a bachelor's or master's degree, 61% were non-Hispanic white, and 67% reported incomes of US$75,000 or higher. At baseline 5/31 planned to exclusively breastfeed for 4–6 months and 5/33 planned to breastfeed for 6–12 months. Post-intervention there was a 200% increase (15/31 in the exclusively breastfeeding 4–6 month group and a 160% increase (13/33 in the 6–12 month duration group. Actual in-hospital exclusivity rates were 61%, 6-month duration rates were 73%, and 12-month rates were 33%. Over 75% of mothers reported feeling successful. Conclusion This small pilot educational program may have significant

    Although senior medical students at the University of Rochester School of Medicine and Dentistry (URSMD) have a long history of teaching junior peers, no formal educational training existed for students until 2007. The Medical Education Pathway (MEP) at the URSMD is a longitudinal student-as-teacher program that addresses both the local precedent of medical student teaching and the ongoing need to prepare students for teaching in residency and beyond. In 2007, administrative faculty spearheaded efforts to create the MEP Committee, whose members then designed and implemented an elective curriculum. The curriculum balances didactics and experiential learning. A rigorous two-step application process precedes acceptance into the MEP. Participating students receive mentoring, assessment, and formative feedback on lecture delivery and leadership of various small-group formats. Since 2007, 89 students have enrolled in the MEP: 49 have successfully completed it, and 40 are currently enrolled. MEP students teach in basic science and clinical courses, and they regularly make novel contributions to the medical school curriculum. Student learner peers demonstrate an ability to give constructive feedback to MEP students. Exit survey comments demonstrate that the MEP influences participating students' career plans. Lessons learned from implementing the MEP include the importance of institutional support, dedicated faculty who value student teaching, and flexibility in scheduling. Future improvements to the MEP include enhancing the assessment process and tracking the careers of graduates as outcome data. The MEP serves as a model for a successful student-as-teacher program in other institutions and settings.

    During 2006 Lawrence Berkeley National Laboratory (LBNL) and the Demand Response Research Center (DRRC) performed a technology evaluation for the Pacific Gas and Electric Company (PG&E) Emerging Technologies Programs. This report summarizes the design, deployment, and results from the 2006 Automated Critical Peak Pricing Program (Auto-CPP). The program was designed to evaluate the feasibility of deploying automation systems that allow customers to participate in critical peak pricing (CPP) with a fully-automated response. The 2006 program was in operation during the entire six-month CPP period from May through October. The methodology for this field study included site recruitment, control strategy development, automation system deployment, and evaluation of sites' participation in actual CPP events through the summer of 2006. LBNL recruited sites in PG&E's territory in northern California through contacts from PG&E account managers, conferences, and industry meetings. Each site contact signed a memorandum of understanding with LBNL that outlined the activities needed to participate in the Auto-CPP program. Each facility worked with LBNL to select and implement control strategies for demand response and developed automation system designs based on existing Internet connectivity and building control systems. Once the automation systems were installed, LBNL conducted communications tests to ensure that the Demand Response Automation Server (DRAS) correctly provided and logged the continuous communications of the CPP signals with the energy management and control system (EMCS) for each site. LBNL also observed and evaluated Demand Response (DR) shed strategies to ensure proper commissioning of controls. The communication system allowed sites to receive day-ahead as well as day-of signals for pre-cooling, a DR strategy used at a few sites. Measurement of demand response was conducted using two different baseline models for estimating peak load savings. One

    Most of the U.S. population is affiliated with faith-based organizations (FBOs) and regularly attends services. Health and wellness activities (HWA) delivered through FBOs have great potential for reach, but the number of FBOs offering health programs and the characteristics of these programs are currently unknown. The purpose of this study was to better understand rates, characteristics, and factors influencing faith-based HWA across the United States. Faith leaders (N = 844) completed an online survey assessing faith leader demographics and health, FBO demographics (e.g., denomination, size, location, diversity), and details of HWA within their FBO. Respondents were primarily White (93%), male (72%), middle-aged (53.2 ± 12.1 years), and affiliated with Methodist (42.5%) or Lutheran (20.2%) denominations. Although most faith leaders report meeting physical activity recommendations (56.5%), most were overweight/obese (77.4%), did not meet fruit and vegetable recommendations (65.9%), and had been diagnosed with 1.25 ± 1.36 chronic diseases. Respondents reported offering 4.8 ± 3 HWA within their FBO over the past 12 months. Most common HWA included clubs/teams related to physical activity (54.8%), individual-level health counseling (54%), and providing health/wellness pamphlets. Leaders cited a lack of lay leadership (48.1%) and financial resources for staff time (47.8%) as the most common barriers to HWA. An increase in interest/awareness in health topics from FBO members was the most common facilitator for HWA (66.5%). Although faith-based HWA are prevalent nationally, types of HWA and the factors influencing HWA are dependent on FBO characteristics. Future faith-based interventions should consider existing capabilities and moderating factors for HWA.

    Childhood obesity is a health care crisis according to the leading pediatric advocacy groups (National Medical Association, American Academy of Pediatrics, and American Diabetes Association) and the White House. The problem has reached epidemic proportions for all children, but it has an even greater impact on racial minorities. The subject of childhood obesity can lead to a host of medical, psychological, and social problems, including low self-esteem and discrimination.We wrote an interventional children's book and workbook (The Tale of Two Athletes: The Story of Jumper and The Thumper) and developed a three-step intervention based on the narrative. The intervention's purpose is to increase public awareness, reduce stigma, and to help members of underserved communities become more comfortable discussing obesity. In classrooms and other community settings, a storied education program is presented to students of various ages. Interactive storytelling is the first step: live narration with direct listening and active participation. Didactic information on obesity is shared, including a sociocultural explanation for why the issue is more problematic among racial minorities. The audience is then introduced to the story of Jumper and The Thumper, two larger-than-life characters who experience different outcomes as a result of their choices about diet and exercise. True examples are described during the narration about these two young men, accompanied by cartoons and photographs for visual emphasis.The next step is reading: audience members are provided with a book to reinforce what was learned. Readers are allowed to more closely examine the importance of making healthy choices.Practicing positive behaviors and decision making through games and exercises from the companion workbook is the final step. These activities help children and their families live a healthier lifestyle. The goal is that these three steps, linked to a common narrative, will have a meaningful

    The work is conducted in the framework of the European programme SIDDACLICH (SImulation, Diagnosis and Direction of the Anthropogenic CLImate CHange), co-ordinated by DKRZ (Deutsches Klimarechenzentrum) of Hamburg. This project aims to perform and analyze climatic simulations with coupled models in order to study detection and impact of possible climate change linked to human activities. EDF/R and D D contribution to this project is limited to the delivery of diagnosis programs concerning acetylacetone blocking detection, in order to permit the evaluation of the impact of climate change on this type of situation from the results of coupled simulations performed in the project. First, two blocking indexes had been coded from works of Mullen and Kaas and Branstator, reported in the literature and applied to evaluate the impact of the augmentation of CO{sub 2} gas atmospheric concentration on a situation of this type, staring from the results of different equilibrium simulation results of atmospheric only simulations performed in the framework of a previous programme on Anthropogenic Climate Change. Then, these indexes have been confronted with a more commonly used index, the Tibaldi et al. index, using a long series of data covering the period 1963-1988, in order to have an idea of the situations detected by each index for the Euro-Atlantic sector in winters for which the situation is well known.

    Investigations of regulatory issues such as vessel integrity over plant life, vessel failure, and sufficiency of current codes Standard Review Plans (SRP`s) and Guides for license renewal can be greatly expedited by the use of a well-designed computerized data base. Also, such a data base is essential for the validation of embrittlement prediction models by researchers. The Power Reactor Embrittlement Data Base (PR-EDB) is such a comprehensive collection of data for US commercial nuclear reactors. The current version of the PR-EDB contains the Charpy test data that were irradiated in 252 capsules of 96 reactors and consists of 207 data points for heat-affected-zone (HAZ) materials (98 different HAZ), 227 data points for weld materials (105 different welds), 524 data points for base materials (136 different base materials), including 297 plate data points (85 different plates), 119 forging data points (31) different forging), and 108 correlation monitor materials data points (3 different plates). The data files are given in dBASE format and can be accessed with any computer using the DOS operating system. ``User-friendly`` utility programs are used to retrieve and select specific data, manipulate data, display data to the screen or printer, and to fit and plot Charpy impact data. The results of several studies investigated are presented in Appendix D.

    The Centers of Disease Control and Prevention have declared prescription drug abuse an epidemic in the United States. However, demographic data correlating prescription-related deaths with actual prescriptions written is not well described. The purpose of this study is to compare toxicology reports on autopsy for prescription-related deaths with Prescription Drug Monitor Program (PDMP) data. This is a retrospective analysis comparing 2013 San Diego Medical Examiner data on 254 unintentional prescription-related deaths obtained for 12 months before death with data from the California PDMP. Data were analyzed on age, sex, whether there was information on the PDMP, types and quantities of prescribed medications, number of pharmacies and providers involved, and whether there was a match between the Medical Examiner toxicology report and data from the PDMP. In 2013, there were 254 unintentional prescription-related deaths; 186 patients (73%) had PDMP data 12 months before death. Ingesting prescription medications with illicit drugs, alcohol, and/or over-the-counter medications accounted for 40% of the unintentional deaths. Opioids were responsible for the majority of single medication deaths (36; 70.6%). The average number of prescriptions was 23.5 per patient, and the average patient used 3 pharmacies and had 4.5 providers. Chronic prescription use was found in 68.8% of patients with PDMP data. The PDMP data highlight important patterns that can provide valuable insight to clinicians making decisions regarding types and amounts of medications they prescribe. Although there is no guaranteed solution to prevent prescription-related deaths, PDMP data can be useful to prevent coprescribing and medication interaction and by following best clinical practices.

  3. The Sidebar Computer Program, a seismic-shaking intensity meter: users' manual and software description

    Evans, John R.

    2003-01-01

    The SideBar computer program provides a visual display of seismic shaking intensity as recorded at one specific seismograph. This software allows a user to tap into the seismic data recorded on that specific seismograph and to display the overall level of shaking at the single location where that seismograph resides (usually the same place the user is). From this shaking level, SideBar also estimates the potential for damage nearby. SideBar cannot tell you the “Richter magnitude” of the earthquake (see box), only how hard the ground shook locally and this estimate of how much damage is likely in the neighborhood. This combination of local effects is called the “seismic intensity”. SideBar runs on a standard desktop or laptop PC, and is intended for the media, schools, emergency responders, and any other group hosting a seismograph and who want to know immediately after an earthquake the levels of shaking measured by that instrument. These local values can be used to inform the public and help initiate appropriate local emergency response activities in the minutes between the earthquake and availability of the broader coverage provided by the USGS over the Web, notably by ShakeMap. For example, for instruments installed in schools, the level of shaking and likely damage at the school could immediately be Web broadcast and parents could quickly determine the likely safety of their children—their biggest postearthquake concern. Also, in the event of a Web outage, SideBar may be a continuing primary source of local emergency response information for some additional minutes. Specifically, SideBar interprets the peak level of acceleration (that is, the force of shaking, as a percentage of the force of gravity) as well as the peak velocity, or highest speed, at which the ground moves. Using these two basic measurements, SideBar computes what is called Instrumental Intensity—a close approximation of the Modified Mercalli Intensity scale, or “MMI” (using the

    Health care professionals are expected to build decisions upon evidence. This implies decisions based on the best available, current, valid and relevant evidence, informed by clinical expertise and patient values. A multi-professional master's program in evidence-based practice was developed and offered. The aims of this study were to explore how students in this program viewed their ability to apply evidence-based practice and their perceptions of what constitute necessary conditions to implement evidence-based practice in health care organizations, one year after graduation. A qualitative descriptive design was chosen to examine the graduates' experiences. All students in the first two cohorts of the program were invited to participate. Six focus-group interviews, with a total of 21 participants, and a telephone interview of one participant were conducted. The data was analyzed thematically, using the themes from the interview guide as the starting point. The graduates reported that an overall necessary condition for evidence-based practice to occur is the existence of a "readiness for change" both at an individual level and at the organizational level. They described that they gained personal knowledge and skills to be "change-agents" with "self-efficacy, "analytic competence" and "tools" to implement evidence based practice in clinical care. An organizational culture of a "learning organization" was also required, where leaders have an "awareness of evidence- based practice", and see the need for creating "evidence-based networks". One year after graduation the participants saw themselves as "change agents" prepared to improve clinical care within a learning organization. The results of this study provides useful information for facilitating the implementation of EBP both from educational and health care organizational perspectives.

    Internationalization of practical training in health and social care study programs is an important aspect of higher education. However, field mentors' and classroom teachers' competence in guiding culturally diverse students varies widely in European countries, and the majority does not have enough training in guiding foreign students. This study aimed to examine which factors enhance the efficacy of international practical placement experiences in health and social care study programs. A qualitative descriptive case study design was used. The study was conducted at six higher education institutions-two in Finland and one in Croatia, Estonia, the Netherlands and Slovenia. A convenience sample of 14 mentors, 15 teachers and 14 students with international experiences from six higher education institutions which are part of the Bologna Process was recruited. The data were collected from six focus groups using a semi-structured questionnaire based on a literature review. Each higher education institution conducted one group interview that was tape-recorded, transcribed and analysed for themes. Participants made several recommendations for enhancing the practical placement experience of students, teachers, and mentors. Most recommendations dealt with practical supervision of students. Three major themes noted were: 'Attitudes towards internationalization of practical placements', 'Factors impacting the international placement experience', and 'Pedagogical methods used and structural support available for internationalization.' The study highlights the need for strengthening the multicultural knowledge and skills of mentors and teachers. The findings provide practical guidelines for improving the international placement experience across health and social care fields. Copyright © 2016 Elsevier Ltd. All rights reserved.

    The purpose of this study was twofold: 1) to examine website content provided by U.S. and Canadian pediatric dentistry residency programs, and 2) to understand aspects of program websites that dental students report to be related to their interests. Sixty-eight program websites were reviewed by five interprofessional evaluators. A thirty-six-item evaluation form was organized into 1) program descriptive items listed on the American Academy of Pediatric Dentistry (AAPD) website (n=21); 2) additional program descriptive items not listed on the AAPD website but of interest (n=9); and 3) items related to website interface design (n=5). We also surveyed fifty-four dental students regarding their interest in various aspects of program descriptions. The results of this study suggest that pediatric dentistry residency programs in general tend to provide identical or less information than what is listed on the AAPD website. The majority of respondents (76 percent) reported that residency program websites would be their first source of information about advanced programs. The greatest gap between the available website information and students' interests exists in these areas: stipend and tuition information, state licensure, and program strengths. Pediatric dentistry residency programs underutilize websites as a marketing and recruitment tool and should incorporate more information in areas of students' priority interests.

Antipsychotic augmentation treatment with aripiprazole and quetiapine is approved for MDD patients and can achieve a high remission rate. This study aimed to examine how psychiatrists in Taiwan choose medications and how that choice is influenced by health insurance payments and administrative policy.Design: Descriptive study.Outcome measures: Eight questions about the choice of treatment strategy and atypical antipsychotics, and the reason to choose aripiprazole.Intervention: We designed an augmentation strategy questionnaire for psychiatrists whose patients had a poor response to antidepressants, and handed it out during the annual meeting of the Taiwanese Society of Psychiatry in October 2012. It included eight questions addressing the choice of treatment strategy and atypical antipsychotics, and the reason whether or not to choose aripiprazole as the augmentation antipsychotic.Results: Choosing antipsychotic augmentation therapy or switching to other antidepressant strategies for MDD patients with an inadequate response to antidepressants was common with a similar probability (76.1% vs 76.4%. The most frequently used antipsychotics were aripiprazole and quetiapine, however a substantial number of psychiatrists chose olanzapine, risperidone, and sulpiride. The major reason for not choosing aripiprazole was cost (52.1%, followed by insurance official policy audit and deletion in the claims review system (30.1%.Conclusion: The prescribing

    Klahr, Sabine Christine

    This study analyzed and compared the program designs of international exchange and internship programs for engineering students in the United States and the European Union (E.U.) as well as the extent to which these programs have removed barriers to study abroad. The purpose of this study was to provide recommendations for the design of international programs in the U.S. that would increase the proportion of engineering students who choose to study or intern abroad. Coordinators of international programs in engineering were surveyed about their perceptions of program success and a number of variables related to program design. A Chi-Square Test of Independence of (A) program success and (B) European and U.S. programs (i.e. institution location) cross-tabulated with all other variables and each other indicated those variables that contribute to the success of programs and those variables that are associated with either U.S. or European programs. In addition, all programs were described and the answers to open-ended survey questions were analyzed quantitatively. The analyses indicated that European programs tend to be more successful in implementing study/intern abroad programs for engineering students than U.S. programs. The elements of program design contributing to the greater success of European programs and the success of specific U.S. programs were described. In addition, the characteristics of overall successful programs (U.S. and E.U. data combined) were explained. The results indicated that successful programs tend to: (1) be promoted by the college and/or departments of engineering, (2) offer study/intern abroad opportunities in English-speaking settings, (3) award full credit at the home institution for required engineering courses completed at the host institution, (4) offer scholarships and financial aid for participation in the program, (5) require participating students to have completed their second year of university course work prior to applying to

    The current study describes the psychometric properties of a scale (entitled "Substance Use Disorder Outcome Scale-10 items" or 10-Item Substance Use Disorder Outcome Scale) designed for longitudinal studies. Sixteen male veterans attending a substance use disorder recovery clinic were studied over a 2-year period. The attending nurse and physician conducted four, 10-Item Substance Use Disorder Outcome Scale scale ratings, each encompassing a 6-month period, for each participant. Analyses involved scale descriptive results, Cronbach alpha scores, effects of deleting the item on Cronbach alpha scores for the remaining items, and item-to-scale correlations across the four periods, plus three exploratory studies. Scale scores showed skewness p ≤ 1.0 and Cronbach alphas of 0.89 to 0.93. Six of 10 items correlated with total scale scores at 3 or 4 rating periods at p ≤ 0.005. Two items showed p ≤ 0.005 correlations only in the first two periods, and two items showed p ≤ 0.005 correlations only in the last two periods. Exploratory analyses revealed some item convergence over time plus non-significant associations with long-standing demographic and clinical variables. Desirable 10-Item Substance Use Disorder Outcome Scale psychometric properties included normal distribution, excellent Cronbach alphas, and high item-to-score correlations, all of which persisted over time.

Using the program's central database, we reviewed all approved projects since 2001 and tabulated them by year, combatant command, country, and key word. We also reviewed the project descriptions of projects funded between January 1, 2006, and February 9, 2008, and examined how their activities varied by combatant command and year. Of the 5395 projects in the database, 2097 were funded. Projects took place in more than 90 countries, with Southern, Pacific, and Africa Command hosting the greatest number. The most common types of projects were school, health, disaster response, and water infrastructure construction, and disaster-response training. The "global war on terror" was the key word most frequently tagged to project descriptions. Project descriptions lacked stated goals as well as implementation and coordination strategies with potential partners, and did not report outcome or impact indicators. The geographic reach of the program is vast and projects take place in a wide variety of public sectors. Yet their security and civilian assistance value remains unclear given the lack of stated project goals, implementation strategies, or measures of effectiveness. To facilitate transparency and policy discussion, we recommend project proposals include hypotheses as to how they will enhance US security, their relevance to the public sector they address, and outcome and impact indicators that can assess their value and effectiveness.

    In recent years, mentoring programs for medical students have been increasingly implemented in medical schools in Germany. This article describes a voluntary mentoring program for students, which is differentiated into a common mentoring program (AP), a mentoring program for excellent students (EP) and a mentoring plus program (PP) for students with academic difficulties, and its evaluation.The evaluation is based on annual evaluation surveys among the participating mentees, who evaluate the mentoring relationship as well as the impact on their studies.The three student groups differ significantly with regard to sociodemographic variables. The satisfaction with the mentoring program is generally high: 84-94% are mentored by their preferred mentor, the majority assesses the conversational atmosphere as open (78-91%), and 89-98% would recommend participation in the program to others. The programs differ with regard to specific aspects. While PP mentees report the highest ratings on the mentor's accessibility, trustworthiness and feedback, EP mentees report the highest ratings on the mentor's competence as well as increased identification with the faculty and early career promotion through the mentoring program.The different assessments of the three programs as well as the generally high acceptance and satisfaction ratings indicate that such a differentiated mentoring program provides a framework of individual support, which is highly appreciated by most students.

    Student-written items were compared with teacher-written items on an objective examination given to first year medical students. While student scores were higher on the student-written items than on teacher-written items, there was a positive correlation between the scores. Student items did not differ from teacher items in the course, according to student ratings of emphasis. As a by-product of this study, correlations were found which suggest that student scores on an item often reflect the degree of teaching emphasis given the content area of the item rather than the inherent difficulty of the content. It is suggested that further research is needed to determine whether students learn through the process of writing examination items. Therefore, if the process proves to be educational, this study indicates that it will be feasible to incorporate the student-constructed items in examinations.

    Although, child mental health problems are widespread, few get adequate treatment, and there is a severe shortage of child psychiatrists. To address this public health need many states have adopted collaborative care programs to assist primary care to better assess and manage pediatric mental health concerns. This report adds to the small literature on collaborative care programs and describes one large program that covers most of New York state. CAP PC, a component program of New York State's Office of Mental Health (OMH) Project TEACH, has provided education and consultation support to primary care providers covering most of New York state since 2010. The program is uniquely a five medical school collaboration with hubs at each that share one toll free number and work together to provide education and consultation support services to PCPs. The program developed a clinical communications record to track information about all consultations which forms the basis of much of this report. 2-week surveys following consultations, annual surveys, and pre- and post-educational program evaluations have also been used to measure the success of the program. CAP PC has grown over the 6years of the program and has provided 8013 phone consultations to over 1500 PCPs. The program synergistically provided 17,523 CME credits of educational programming to 1200 PCPs. PCP users of the program report very high levels of satisfaction and self reported growth in confidence. CAP PC demonstrates that large-scale collaborative consultation models for primary care are feasible to implement, popular with PCPs, and can be sustained. The program supports increased access to child mental health services in primary care and provides child psychiatric expertise for patients who would otherwise have none. Copyright © 2017.

    Analyzing test items is a skill that must be mastered by prospective teachers, in order to determine the quality of test questions which have been written. The main aim of this research was to describe the effectiveness of authentic task to foster the student's skill for analyzing test items involving validity, reliability, item discrimination index, level of difficulty, and distractor functioning through the authentic task. The participant of the research is students of science education study program, science and mathematics faculty, Universitas Negeri Surabaya, enrolled for assessment course. The research design was a one-group posttest design. The treatment in this study is that the students were provided an authentic task facilitating the students to develop test items, then they analyze the items like a professional assessor using Microsoft Excel and Anates Software. The data of research obtained were analyzed descriptively, such as the analysis was presented by displaying the data of students' skill, then they were associated with theories or previous empirical studies. The research showed the task facilitated the students to have the skills. Thirty-one students got a perfect score for the analyzing, five students achieved 97% mastery, two students had 92% mastery, and another two students got 89% and 79% of mastery. The implication of the finding was the students who get authentic tasks forcing them to perform like a professional, the possibility of the students for achieving the professional skills will be higher at the end of learning.

    used in other programs that need to implement geochemical calculations; for example, transport codes. Charting capabilities have been added to some versions of PHREEQC. Charting capabilities have been added to Windows distributions of PHREEQC version 3. (Charting on Linux requires installation of Wine.) The keyword data block USER_GRAPH allows selection of data for plotting and manipulation of chart appearance. Almost any results from geochemical simulations (for example, concentrations, activities, or saturation indices) can be retrieved by using Basic language functions and specified as data for plotting in USER_GRAPH. Results of transport simulations can be plotted against distance or time. Data can be added to a chart from tab-separated-values files. All input for PHREEQC version 3 is defined in keyword data blocks, each of which may have a series of identifiers for specific types of data. This report provides a complete description of each keyword data block and its associated identifiers. Input files for 22 examples that demonstrate most of the capabilities of PHREEQC version 3 are described and the results of the example simulations are presented and discussed.

    To describe and assess an interdisciplinary research training program for graduate students, postdoctoral fellows, and clinical fellows focused on radiation medicine; funded by the Canadian Institutes for Health Research since 2003, the program entitled "Excellence in Radiation Research for the 21st Century" (EIRR21) aims to train the next generation of interdisciplinary radiation medicine researchers. Online surveys evaluating EIRR21 were sent to trainees (n=56), mentors (n=36), and seminar speakers (n=72). Face-to-face interviews were also conducted for trainee liaisons (n=4) and participants in the international exchange program (n=2). Overall response rates ranged from 53% (mentors) to 91% (trainees). EIRR21 was well received by trainees, with the acquisition of several important skills related to their research endeavors. An innovative seminar series, entitled Brainstorm sessions, imparting "extracurricular" knowledge in intellectual property protection, commercialization strategies, and effective communication, was considered to be the most valuable component of the program. Networking with researchers in other disciplines was also facilitated owing to program participation. EIRR21 is an innovative training program that positively impacts the biomedical community and imparts valuable skill sets to foster success for the future generation of radiation medicine researchers.

    Augmentative and alternative communication (AAC) promotes communicative participation and language development for young children with complex communication needs. However, the motor, linguistic, and cognitive demands of many AAC technologies restrict young children's operational use of and influence over these technologies. The purpose of the current study is to better understand young children's participation in programming vocabulary "just in time" on an AAC application with minimized demands. A descriptive study was implemented to highlight the participation of 10 typically developing toddlers (M age: 16 months, range: 10-22 months) in just-in-time vocabulary programming in an AAC app with visual scene displays. All 10 toddlers participated in some capacity in adding new visual scene displays and vocabulary to the app just in time. Differences in participation across steps were observed, suggesting variation in the developmental demands of controls involved in vocabulary programming. Results from the current study provide clinical insights toward involving young children in AAC programming just in time and steps that may allow for more independent participation or require more scaffolding. Technology designed to minimize motor, cognitive, and linguistic demands may allow children to participate in programming devices at a younger age.

  10. Item Overexposure in Computerized Classification Tests Using Sequential Item Selection

    Directory of Open Access Journals (Sweden)

    Alan Huebner

    2012-06-01

    Full Text Available Computerized classification tests (CCTs often use sequential item selection which administers items according to maximizing psychometric information at a cut point demarcating passing and failing scores. This paper illustrates why this method of item selection leads to the overexposure of a significant number of items, and the performances of three different methods for controlling maximum item exposure rates in CCTs are compared. Specifically, the Sympson-Hetter, restricted, and item eligibility methods are examined in two studies realistically simulating different types of CCTs and are evaluated based upon criteria including classification accuracy, the number of items exceeding the desired maximum exposure rate, and test overlap. The pros and cons of each method are discussed from a practical perspective.

    2012-07-01

    Full Text Available Abstract For over 15 years the Australian Agency for International Development (AusAID has been a leading donor for harm reduction projects in Southeast Asia. The recent AusAID-supported harm reduction projects of greatest significance have included the Asia Regional HIV/AIDS Project (AHRP, from 2002 until 2007,1 and the HIV/AIDS Asia Regional Program (HAARP, from 2007 until 2015.2 Both projects included in their design specific strategies for engaging with law enforcement agencies at country level. The main focus of these strategies has been to develop law enforcement harm reduction policy and curriculum, and the design and implementation of specific harm reduction training for law enforcement officers. In July 2008, the Australian Development Research Awards (ADRA funded the Nossal Institute for Global Health at the University of Melbourne to establish a research project created to assess the influence of harm reduction programs on the policy and operational practices of law enforcement agencies in Southeast Asia, known as the LEHRN Project (Law Enforcement, Harm Reduction, Nossal Institute Project. The ADRA is a unique grant research mechanism that specifically funds development research to improve the understanding and informed decision making of the implementation of Australian aid effectiveness. While the need to engage law enforcement when establishing harm reduction programs was well documented, little was known about the impact or influence of harm reduction programs on policy and practices of law enforcement agencies. The LEHRN Project provided the opportunity to assess the impact of harm reduction programs on law enforcement in Southeast Asia, with a focus on Vietnam, Cambodia and Lao PDR.

    1976-01-01

    A computer program for analyzing inviscid, isentropic, transonic flow past 3-D swept configurations is presented. Some basic aspects of the program are: (1) the free-stream Mach number is restricted only by the isentropic assumption; (2) weak shock waves are automatically located wherever they occur in the flow; (3) the finite-difference form of the full equation for the velocity potential is solved by the method of relaxation, after the flow exterior to the airfoil is mapped to the upper half plane; (4) the mapping procedure allows exact satisfaction of the boundary conditions and use of supersonic free stream velocities; (5) the finite difference operator is locally rotated in supersonic flow regions so as to properly account for the domain of dependence; and (6) the relaxation algorithm was stabilized using criteria from a time-like analogy.

    This case describes the outcomes of a multifaceted rehabilitation program including body weight-supported overground gait training (BWSOGT) in a nonambulatory child with cerebral palsy (CP) and the impact of this treatment on the child's functional mobility. The patient is a nonambulatory 10-year-old female with CP who during an inpatient rehabilitation stay participated in direct, physical therapy 6 days per week for 5 weeks. Physical therapy interventions included stretching of her bilateral lower extremities, transfer training, bed mobility training, balance training, kinesiotaping, supported standing in a prone stander, two trials of partial weight-supported treadmill training, and for 4 weeks, three to five times per week, engaged in 30 minutes of BWSOGT using the Up n' go gait trainer, Lite Gait Walkable, and Rifton Pacer gait trainer. Following the multifaceted rehabilitation program, the patient demonstrated increased step initiation, increased weight bearing through bilateral lower extremities, improved bed mobility, and increased participation in transfers. The child's Gross Motor Functional Measure (GMFM) scores increased across four dimensions and her Physical Abilities and Mobility Scale (PAMS) increased significantly. This case report illustrates that a multifaceted rehabilitation program including BWSOGT was an effective intervention strategy to improve functional mobility in this nonambulatory child with CP.

    Full Text Available In 1990 the organizations responsible for Finnish dairy breeding established an open nucleus multiple ovulation and embryo transfer (MOET breeding program called ASMO. The aim was, besides to test effectiveness of MOET, to improve the protein to fat ratio in milk produced by Finnish Ayrshires but without sacrificing the progress in protein yield. The relative weights of traits were such that equal importance was assigned to protein % and protein yield. Negative weight was assigned to fat % to ensure it remained unaltered. The MOET work continued until 1994 after which the performance of selected animals has been monitored. During the five years the scheme operated, 276 cows were flushed for embryos, and 2751 embryos were recovered, of which 1810 were transferable. More than 1600 embryos were transferred to recipients, and 813 calves were born. Eighty bull calves were sold for the artificial insemination test scheme. In December 1995 the first 125 ET daughters were evaluated with the national animal model program. Their mean estimated breeding values (EBVs were +0.13 for protein % and -0.18 for fat % compared with the genetic base of progeny tested sires born in 1986-1988, and the protein yield EBVs were 12 kg above the genetic base. Despite the efficiency of selection, the program was discontinued in 1994. Due to the difficulty of maintaining sufficient control over donor animals, there were fewer than expected embryos per flush and also too few flushes per donor.;

To describe the psychopathological characteristics and neurocognitives profiles of the offspring of bipolar type I parents. And to identify the presence of sub-syndromal symptoms in all the symptom domains. A descriptive and cross-sectional study was conducted on 110 offspring between 6 and 30 years old. Semi-structured diagnostic interviews were performed. The intelectual coeficient was determined and a neuropsychological assessment was performed on 89 offspring. The most prevalent disorder in the offspring was ADHD (27.6%), with major depression (15.5%) and separation anxiety (14.1%) also being prevalent. Seven patients of the sample were diagnosed with bipolar disorder. There was a statistically significant difference between the age groups for ADHD prevalence. The most frequent sub-syndromal symptoms were observed in the disruptive group. Alterations in the cognitive domains: attention, verbal fluency, work memory, and speed of information processing, were observed in the group younger than 18 years. The offspring of bipolar parents have an elevated rate of psychopathology and cognitive alterations. They are a high risk population for the development of mental disease. These subjects also require close longitudinal observation and early and preventive therapeuthic interventions. Copyright © 2014 Asociación Colombiana de Psiquiatría. Publicado por Elsevier España.

    2017-01-01

    Full Text Available A multi item profit maximization inventory model is developed in fuzzy stochastic environment. Demand is taken as Stock dependent demand. Available storage space is assumed to be imprecise and vague in nature. Impreciseness has been expressed by linear membership function. Purchasing cost and investment constraint are considered to be random and their randomness is expressed by normal distribution. The model has been formulated as a fuzzy stochastic programming problem and reduced to corresponding equivalent fuzzy linear programming problem. The model has been solved by using fuzzy linear programming technique and illustrated numerically.

  3. Problems with the factor analysis of items: Solutions based on item response theory and item parcelling

    Directory of Open Access Journals (Sweden)

    Gideon P. De Bruin

    2004-10-01

    Full Text Available The factor analysis of items often produces spurious results in the sense that unidimensional scales appear multidimensional. This may be ascribed to failure in meeting the assumptions of linearity and normality on which factor analysis is based. Item response theory is explicitly designed for the modelling of the non-linear relations between ordinal variables and provides a strong alternative to the factor analysis of items. Items may also be combined in parcels that are more likely to satisfy the assumptions of factor analysis than do the items. The use of the Rasch rating scale model and the factor analysis of parcels is illustrated with data obtained with the Locus of Control Inventory. The results of these analyses are compared with the results obtained through the factor analysis of items. It is shown that the Rasch rating scale model and the factoring of parcels produce superior results to the factor analysis of items. Recommendations for the analysis of scales are made. Opsomming Die faktorontleding van items lewer dikwels misleidende resultate op, veral in die opsig dat eendimensionele skale as meerdimensioneel voorkom. Hierdie resultate kan dikwels daaraan toegeskryf word dat daar nie aan die aannames van lineariteit en normaliteit waarop faktorontleding berus, voldoen word nie. Itemresponsteorie, wat eksplisiet vir die modellering van die nie-liniêre verbande tussen ordinale items ontwerp is, bied ’n aantreklike alternatief vir die faktorontleding van items. Items kan ook in pakkies gegroepeer word wat meer waarskynlik aan die aannames van faktorontleding voldoen as individuele items. Die gebruik van die Rasch beoordelingskaalmodel en die faktorontleding van pakkies word aan die hand van data wat met die Lokus van Beheervraelys verkry is, gedemonstreer. Die resultate van hierdie ontledings word vergelyk met die resultate wat deur ‘n faktorontleding van die individuele items verkry is. Die resultate dui daarop dat die Rasch

    The Emory Prevention Research Center's Cancer Prevention and Control Research Network mini-grant program funded faith-based organizations to implement policy and environmental change to promote healthy eating and physical activity in rural South Georgia. This study describes the existing health promotion environment and its relationship to church member behavior. Cross-sectional. Data were obtained from parishioners of six churches in predominantly rural South Georgia. Participants were 319 church members with average age of 48 years, of whom 80% were female and 84% were black/African-American. Questionnaires assessed perceptions of the existing church health promotion environment relative to nutrition and physical activity, eating behavior and intention to use physical activity facilities at church, and eating and physical activity behaviors outside of church. Multiple regression and ordinal logistic regression using generalized estimating equations were used to account for clustered data. Results indicate that delivering messages via sermons and church bulletins, having healthy eating programs, and serving healthy foods are associated with participants' self-reported consumption of healthy foods at church (all p values ≤ .001). Serving more healthy food and less unhealthy food was associated with healthier eating in general but not to physical activity in general (p values ≤ .001). The church environment may play an important role in supporting healthy eating in this setting and more generally.

    2014-01-01

    Background The clinical effects and potential benefits of nutrition supplementation interventions for persons living with HIV remain largely unreported, despite awareness of the multifaceted relationship between HIV infection and nutrition. We therefore examined descriptive characteristics and nutritional outcomes of the Food by Prescription (FBP) nutrition supplementation program in Nyanza Province, Kenya. Methods Demographic, health, and anthropometric data were gathered from a retrospective cohort of 1,017 non-pregnant adult patients who enrolled into the FBP program at a Family AIDS Care and Education Services (FACES) site in Nyanza Province between July 2009 and July 2011. Our primary outcome was FBP treatment success defined as attainment of BMI>20, and we used Cox proportional hazards to assess socio-demographic and clinical correlates of FBP treatment success. Results Mean body mass index was 16.4 upon enrollment into the FBP program. On average, FBP clients gained 2.01 kg in weight and 0.73 kg/m2 in BMI over follow-up (mean 100 days), with the greatest gains among the most severely undernourished (BMI 20, though 44.5% achieved a BMI increase ≥0.5. Greater BMI at baseline, younger age, male gender, and not requiring highly active antiretroviral therapy (HAART) were associated with a higher rate of attainment of BMI>20. Conclusion This study reports significant gains in weight and BMI among patients enrolled in the FBP program, though only a minority of patients achieved stated programmatic goals of BMI>20. Future research should include well-designed prospective studies that examine retention, exit reasons, mortality outcomes, and long-term sustainability of nutrition supplementation programs for persons living with HIV.

    The shift of clinical care and teaching to outpatient settings has challenged ambulatory and community-based teachers. To address this challenge, U.S. internal medicine organizations devised "Faculty Development for General Internal Medicine: Generalist Faculty Teaching in Ambulatory Settings," a national program to train leaders to create local faculty development projects. In 1999, teams from all 386 internal medicine training institutions were invited to apply. Participation required an acceptable plan for a local project and inclusion of an institutional leader, residency or clerkship director, and a community-based faculty member on the project team. Team members attended one of three national training conferences held in 1999 and 2000 that included plenary sessions, workshops, and team meetings. Participants were invited to a wrap-up conference to present their accomplishments. One hundred ten teams from 57 university and 53 non-university hospitals attended the training conferences; 412 (93%) participants returned conference evaluations. All sessions were rated highly. Participants preferred workshops and team meetings to plenary sessions. Two hundred thirty-five (57%) would have recommended the training conference to colleagues as an outstanding experience; 148 (36%) as a good experience; and 25 (6%) as a satisfactory experience. Forty-nine teams (122 participants) returned for the wrap up conference where 35 teams presented their local faculty development projects. Cost per team trained was US$11,818. This program demonstrated a national desire for training in teaching skills, reached a broad audience of ambulatory-based clinical teachers, provided highly rated faculty development conferences in teaching skills, and facilitated development of a variety of local projects at modest expense. Partnerships were forged between academic leaders and community-based teachers.

    Full Text Available Abstract Background The Joint Asia Diabetes Evaluation (JADE Program is a web-based program incorporating a comprehensive risk engine, care protocols, and clinical decision support to improve ambulatory diabetes care. Methods The JADE Program uses information technology to facilitate healthcare professionals to create a diabetes registry and to deliver an evidence-based care and education protocol tailored to patients' risk profiles. With written informed consent from participating patients and care providers, all data are anonymized and stored in a databank to establish an Asian Diabetes Database for research and publication purpose. Results The JADE electronic portal (e-portal: http://www.jade-adf.org is implemented as a Java application using the Apache web server, the mySQL database and the Cocoon framework. The JADE e-portal comprises a risk engine which predicts 5-year probability of major clinical events based on parameters collected during an annual comprehensive assessment. Based on this risk stratification, the JADE e-portal recommends a care protocol tailored to these risk levels with decision support triggered by various risk factors. Apart from establishing a registry for quality assurance and data tracking, the JADE e-portal also displays trends of risk factor control at each visit to promote doctor-patient dialogues and to empower both parties to make informed decisions. Conclusions The JADE Program is a prototype using information technology to facilitate implementation of a comprehensive care model, as recommended by the International Diabetes Federation. It also enables health care teams to record, manage, track and analyze the clinical course and outcomes of people with diabetes.

    A case-control study on lung cancer and radon exposure in dwellings has been carried out in Lazio, a high indoor radon region of Central Italy. A total of about 400 cases and 400 controls were recruited and radon concentration was measured in a total of about 1850 dwellings. In each dwelling, radon concentration measurement devices were placed in both the main bedroom and living room for two consecutive six-month periods. Each radon device, enclosed in a sealed polyethylene bag, contains two LR 115 detectors, each being covered by a thin absorber to reduce the alpha-energy within the detector sensitive range. A quality assurance program, described in this paper, was applied in order to reduce radon concentration measurement uncertainty, which have a significant impact on the results of an epidemiological study. The reported internal quality control and intercomparison results are compared with the results of other studies, and show that the radon measurement precision and accuracy obtained in this study can be considered quite good.

    Recovery-oriented care is a guiding principle for mental health services in Australia, and internationally. Recovery-oriented psychiatric rehabilitation supports people experiencing mental illness to pursue a meaningful life. In Australia, people with unremitting mental illness and psychosocial disability are often detained for months or years in secure extended care facilities. Psychiatric services have struggled to provide rehabilitation options for residents of these facilities. Researchers have argued that art participation can support recovery in inpatient populations. This study addressed the research question: Is there a role for the creative arts in the delivery of recovery-oriented psychiatric rehabilitation for people with enduring mental illness and significant psychosocial disability detained in a secure extended care unit? The study had two major aims: to explore the experiences of consumers detained in a rural Australian secure extended care unit of an art therapy project, and to examine the views of nurse managers and an art therapist on recovery-oriented rehabilitation programs with regard to the art therapy project. A qualitative descriptive design guided the study, and a thematic network approach guided data analysis. Ethics approval was granted from the local ethics committee (AU/1/9E5D07). Data were collected from three stakeholders groups. Five consumers participated in a focus group; six managers and the art therapist from the project participated in individual interviews. The findings indicate that consumer participants benefitted from art participation and wanted more access to rehabilitation-focussed programs. Consumer participants identified that art making provided a forum for sharing, self-expression, and relationships that built confidence, absent in the regular rehabilitation program. Nurse manager and the art therapist participants agreed that art participation was a recovery-oriented rehabilitation tool, however, systemic barriers

    Background: The burden of fees for chiropractic services rendered often falls on the patient and must be provided out-of-pocket regardless of their socioeconomic status and clinical need. Universal healthcare coverage reduces the financial barrier to healthcare utilization, thereby increasing the opportunity for the financially disadvantaged to have access to care. In 2011 the Canadian Province of Manitoba initiated a pilot program providing access to chiropractic care within the Mount Carmel Clinic (MCC), a non-secular, non-profit, inner city community health centre. Objective: To describe the initial integration of chiropractic services into a publically funded healthcare facility including patient demographics, referral patterns, treatment practices and clinical outcomes. Method: A retrospective database review of chiropractic consultations in 2011 (N=177) was performed. Results: The typical patient referred for chiropractic care was a non-working (86%), 47.3(SD=16.8) year old, who self-identified as Caucasian (52.2%), or Aboriginal (35.8%) and female (68.3%) with a body mass index considered obese at 30.4(SD=7.0). New patient consultations were primarily referrals from other health providers internal to the MCC (71.2%), frequently primary care physicians (76%). Baseline to discharge comparisons of numeric rating scale scores for the cervical, thoracic, lumbar, sacroiliac and extremity regions all exceeded the minimally clinically important difference for reduction in musculoskeletal pain. Improvements occurred over an average of 12.7 (SD=14.3) treatments, and pain reductions were also statistically significant at pChiropractic services are being utilized by patients, and referring providers. Clinical outcomes indicate that services rendered decrease musculoskeletal pain in an inner city population. PMID:26816049

    The primary aim of the disease management program (DMP) for patients with diabetes mellitus type 2 is to improve the quality of health care and the treatment process. 12 years after its introduction in Germany, there is still no consensus as to whether DMP has been effective in reaching these goals. A retrospective longitudinal population-based study between 2004 and 2015 were conducted to evaluate the DMP for type 2 diabetes in Bavaria using routinely collected patient medical records hold from the National Association of Statutory Health Insurance Physicians of Bavaria. During the first 12 years of DMP, the number of participants increased continually to reach 580,222 in 2015. The proportion of participants older than 70 years increased during the observation from 41.6 to 51.1%. The percentage of smokers increased slightly from 9 to 11%. Similarly, the distribution of body mass index remained constant with approximately 50% of patients having a body mass index >30 kg/m 2 . Control of HbA1c was without an appreciable change over the course, with between 8.3 and 9.4% of all patients with uncontrolled values higher than 8.5%. Prescription of metformin increased from 40.5% in 2004 to 54.1% in 2015. Among patients receiving insulin, the proportion receiving a combined therapy with metformin increased from 28.4% in 2004 to 50.8% in 2015. In contrast, the percentage with insulin monotherapy decreased from 55.4 to 33.7%. The proportion of patients with a diabetic education increased within the course from 12.8 to 29.3%. Data from the German DMP for type 2 diabetes demonstrates an improvement in the quality of care with respect to pharmacotherapy and patient education and therefore to an improved adherence to guidelines. However, no appreciable improvement was observed with regard to smoking status, obesity or HbA1c control.

    The Nonproliferation Alternative Systems Assessment Program (NASAP) has characterized and assessed various reactor/fuel-cycle systems. Volume IX provides, in summary form, the technical descriptions of the reactor/fuel-cycle systems studied. This includes the status of the system technology, as well as a discussion of the safety, environmental, and licensing needs from a technical perspective. This information was then used in developing the research, development, and demonstration (RD and D) program, including its cost and time frame, to advance the existing technology to the level needed for commercial use. Wherever possible, the cost data are given as ranges to reflect the uncertainties in the estimates. Volume IX is divided into three sections: Chapter 1, Reactor Systems; Chapter 2, Fuel-Cycle Systems; and the Appendixes. Chapter 1 contains the characterizations of the following 12 reactor types: light-water reactor; heavy-water reactor; water-cooled breeder reactor; high-temperature gas-cooled reactor; gas-cooled fast reactor; liquid-metal fast breeder reactor; spectral-shift-controlled reactor; accelerator-driven reactor; molten-salt reactor; gaseous-core reactor; tokamak fusion-fisson hybrid reactor; and fast mixed-spectrum reactor. Chapter 2 contains similar information developed for fuel-cycle facilities in the following categories: mining and milling; conversion and enrichment; fuel fabrication; spent fuel reprocessing; waste handling and disposal; and transportation of nuclear materials.

    The YALINA facility is a zero-power, sub-critical assembly driven by a conventional neutron generator. It was conceived, constructed, and put into operation at the Radiation Physics and Chemistry Problems Institute of the National Academy of Sciences of Belarus located in Minsk-Sosny, Belarus. This facility was conceived for the purpose of investigating the static and dynamic neutronics properties of accelerator driven sub-critical systems, and to serve as a neutron source for investigating the properties of nuclear reactions, in particular transmutation reactions involving minor-actinide nuclei. This report provides a detailed description of this facility and documents the progress of research carried out there during a period of approximately a decade since the facility was conceived and built until the end of 2008. During its history of development and operation to date (1997-2008), the YALINA facility has hosted several foreign groups that worked with the resident staff as collaborators. The participation of Argonne National Laboratory in the YALINA research programs commenced in 2005. For obvious reasons, special emphasis is placed in this report on the work at YALINA facility that has involved Argonne's participation. Attention is given here to the experimental program at YALINA facility as well as to analytical investigations aimed at validating codes and computational procedures and at providing a better understanding of the physics and operational behavior of the YALINA facility in particular, and ADS systems in general, during the period 1997-2008.

    Descriptive statistics is the branch of statistics that gives recommendations on how to summarize clearly and simply research data in tables, figures, charts, or graphs. Before performing a descriptive analysis it is paramount to summarize its goal or goals, and to identify the measurement scales of the different variables recorded in the study. Tables or charts aim to provide timely information on the results of an investigation. The graphs show trends and can be histograms, pie charts, "box and whiskers" plots, line graphs, or scatter plots. Images serve as examples to reinforce concepts or facts. The choice of a chart, graph, or image must be based on the study objectives. Usually it is not recommended to use more than seven in an article, also depending on its length.

    Since 1983 apprentices and students 16-19 years of the Canton of Vaud (Switzerland) have been offered various activities in the frame of a school-based health promotion program called "Jeunesse et Santé" (screening, health education...). This paper focuses on the description and the evaluation of emergency care and counseling activities ran by nurses in each school. During one and a half year, 969 adolescents have presented themselves for medical reasons (40%), or for problems of psychosomatic (30%) or psycho-social (30%) nature. Most of the pupils have consulted either spontaneously (40%) or after a screening procedure (40%). 297 youngsters have been sent to another institution for further evaluation and treatment (personal physician, outpatient clinic, social services). Three months after the first consultation, the nurses have contacted both the adolescents an the institutions for an evaluation: A large part of the pupils is satisfied with the help they have received (greater than 90%). However the follow-up seems more difficult to organize and less effective for the adolescents that have presented themselves with psychosocial problems. The paper ends with the advantages and the limitations of ambulatory research performed in the frame of school health activities.

    In December, 1989 Bonneville published Description of Electric Energy Use in Commercial Buildings in the Pacific Northwest, a summary report on the data collected from commercial buildings metered under the End-Use Load and Consumer Assessment Program (ELCAP), for the period 1986 through 1988. Average monthly and annual electric end-use intensities (EUIs, kWh/ft{sup 2}) and average load shapes were presented for nine building types and seven or eight end uses, as well as building totals. This document is a supplement to that report. An additional two and one-half years` data (October 1988 through June 1991) have been collected since the original report, resulting in increased numbers of buildings available for analysis. Additionally, some analytical techniques used in the previous report have been improved and some minor bugs corrected. This supplement differs from the original in the following ways: increased sample sizes; improved analytical techniques; corrected aggregation techniques; eliminated building types; eliminated split plots; included Btu/square foot.

    Caries risk assessment (CRA) is widely recommended for dental caries management. Little is known regarding how practitioners use individual CRA items to determine risk and which individual items independently predict clinical outcomes in children younger than 6 y. The objective of this study was to assess the relative importance of pediatric CRA items in dental providers’ decision making regarding patient risk and in association with clinically evident caries, cross-sectionally and longitudinally. CRA information was abstracted retrospectively from electronic patient records of children initially aged 6 to 72 mo at a university pediatric dentistry clinic (n = 3,810 baseline; n = 1,315 with follow-up). The 17-item CRA form included caries risk indicators, caries protective items, and clinical indicators. Conditional random forests classification trees were implemented to identify and assign variable importance to CRA items independently associated with baseline high-risk designation, baseline evident tooth decay, and follow-up evident decay. Thirteen individual CRA items, including all clinical indicators and all but 1 risk indicator, were independently and statistically significantly associated with student/resident providers’ caries risk designation. Provider-assigned baseline risk category was strongly associated with follow-up decay, which increased from low (20.4%) to moderate (30.6%) to high/extreme risk patients (68.7%). Of baseline CRA items, before adjustment, 12 were associated with baseline decay and 7 with decay at follow-up; however, in the conditional random forests models, only the clinical indicators (evident decay, dental plaque, and recent restoration placement) and 1 risk indicator (frequent snacking) were independently and statistically significantly associated with future disease, for which baseline evident decay was the strongest predictor. In this predominantly high-risk population under caries-preventive care, more individual CRA items

    The Fuel program sustainability is included as one of three programs in a cohesive commitment to increased, sustainable and efficient production and use of indigenous and renewable fuels that are implemented by the Swedish Energy Agency from July 1, 2011 to June 30, 2015. The program focuses on issues of environment and ecological sustainability of the production of biofuels, and systems and resource issues concerning the use. It does not include purely technical issues related to biofuels production or processes in which fuel is converted to heat, electricity or fuel. Questions about fuel supply and fuel processing / scale combustion are treated in the parallel running programs; the Fuel program supply and the Fuel program conversion. The four-year program will commence on July 1, 2011 and will run until June 30, 2015 and has an annual budget of total SEK 16 millions. Ambiguities in the environmental area may through various regulations mean various forms of barriers on the biofuel market. The Fuel program sustainability aims to sort out such ambiguities and, if possible, eliminate such obstacles, identify solutions and develop opportunities. The availability of biofuels and croplands is limited relative to needs. Thus the program also aims to describe the resource efficiency and climate benefits of current biofuel chains, and the possibility of using instruments to stimulate good practice. The program consists of sub-areas that partly overlap. - The sub-area Environment and sustainability focuses on how biofuel production will be designed to meet national and international environmental objectives and sustainability criteria. - The sub-area Biofuels and greenhouse gases describes different climate aspects related to production and exploitation of biofuels. - The sub-area System and market focuses on resource- and climate-efficient solutions in a system perspective, and how the bio-energy system can be affected by policy instruments

    Pritikin, Joshua N; Hunter, Micheal D; Boker, Steven

    2015-06-01

    This paper introduces an Item Factor Analysis (IFA) module for OpenMx, a free, open-source, and modular statistical modeling package that runs within the R programming environment on GNU/Linux, Mac OS X, and Microsoft Windows. The IFA module offers a novel model specification language that is well suited to programmatic generation and manipulation of models. Modular organization of the source code facilitates the easy addition of item models, item parameter estimation algorithms, optimizers, test scoring algorithms, and fit diagnostics all within an integrated framework. Three short example scripts are presented for fitting item parameters, latent distribution parameters, and a multiple group model. The availability of both IFA and structural equation modeling in the same software is a step toward the unification of these two methodologies.

    Rush, Bonnie R; Rankin, David C; White, Brad J

    2016-09-29

    Failure to adhere to standard item-writing guidelines may render examination questions easier or more difficult than intended. Item complexity describes the cognitive skill level required to obtain a correct answer. Higher cognitive examination items promote critical thinking and are recommended to prepare students for clinical training. This study evaluated faculty-authored examinations to determine the impact of item-writing flaws and item complexity on the difficulty and discrimination value of examination items used to assess third year veterinary students. The impact of item-writing flaws and item complexity (cognitive level I-V) on examination item difficulty and discrimination value was evaluated on 1925 examination items prepared by clinical faculty for third year veterinary students. The mean (± SE) percent correct (83.3 % ± 17.5) was consistent with target values in professional education, and the mean discrimination index (0.18 ± 0.17) was slightly lower than recommended (0.20). More than one item-writing flaw was identified in 37.3 % of questions. The most common item-writing flaws were awkward stem structure, implausible distractors, longest response is correct, and responses are series of true-false statements. Higher cognitive skills (complexity level III-IV) were required to correctly answer 38.4 % of examination items. As item complexity increased, item difficulty and discrimination values increased. The probability of writing discriminating, difficult examination items decreased when implausible distractors and all of the above were used, and increased if the distractors were comprised of a series of true/false statements. Items with four distractors were not more difficult or discriminating than items with three distractors. Preparation of examination questions targeting higher cognitive levels will increase the likelihood of constructing discriminating items. Use of implausible distractors to complete a five-option multiple choice

    2005-01-01

    Task Description Language (TDL) is an extension of the C++ programming language that enables programmers to quickly and easily write complex, concurrent computer programs for controlling real-time autonomous systems, including robots and spacecraft. TDL is based on earlier work (circa 1984 through 1989) on the Task Control Architecture (TCA). TDL provides syntactic support for hierarchical task-level control functions, including task decomposition, synchronization, execution monitoring, and exception handling. A Java-language-based compiler transforms TDL programs into pure C++ code that includes calls to a platform-independent task-control-management (TCM) library. TDL has been used to control and coordinate multiple heterogeneous robots in projects sponsored by NASA and the Defense Advanced Research Projects Agency (DARPA). It has also been used in Brazil to control an autonomous airship and in Canada to control a robotic manipulator.

    2009-07-01

    Natural disasters, such as hurricanes, floods, tornados, and tsunami, are becoming a greater problem as climate change impacts our environment. Disasters, whether natural or man made, destroy lives, homes, businesses and the natural environment. Such disasters can happen with little or no warning, leaving hundreds or even thousands of people without medical services, potable water, sanitation, communications and electrical services for up to several weeks. In our modern world, the need for electricity has become a necessity. Modern building codes and new disaster resistant building practices are reducing the damage to homes and businesses. Emergency gasoline and diesel generators are becoming common place for power outages. Generators need fuel, which may not be available after a disaster, but Photovoltaic (solar-electric) systems supply electricity without petroleum fuel as they are powered by the sun. Photovoltaic (PV) systems can provide electrical power for a home or business. PV systems can operate as utility interactive or stand-alone with battery backup. Determining your critical load items and sizing the photovoltaic system for those critical items, guarantees their operation in a disaster.

    2017-08-01

    Intact transition epitope mapping (ITEM) enables rapid and accurate determination of protein antigen-derived epitopes by either epitope extraction or epitope excision. Upon formation of the antigen peptide-containing immune complex in solution, the entire mixture is electrosprayed to translate all constituents as protonated ions into the gas phase. There, ions from antibody-peptide complexes are separated from unbound peptide ions according to their masses, charges, and shapes either by ion mobility drift or by quadrupole ion filtering. Subsequently, immune complexes are dissociated by collision induced fragmentation and the ion signals of the "complex-released peptides," which in effect are the epitope peptides, are recorded in the time-of-flight analyzer of the mass spectrometer. Mixing of an antibody solution with a solution in which antigens or antigen-derived peptides are dissolved is, together with antigen proteolysis, the only required in-solution handling step. Simplicity of sample handling and speed of analysis together with very low sample consumption makes ITEM faster and easier to perform than other experimental epitope mapping methods.

    Counterfeiting of industrial and commercial grade items is an international problem that places worker safety, program objectives, expensive equipment, and security at risk. In order to prevent the introduction of Suspect/Counterfeit Items (S/CI), this information sheet is being made available as a guide to assist in the implementation of S/CI awareness and controls, in conjunction with subcontractor's/supplier's quality assurance programs. When it comes to counterfeit goods, including industrial materials, items, and equipment, no market is immune. Some manufactures have been known to misrepresent their products and intentionally use inferior materials and processes to manufacture substandard items, whose properties can significantly cart from established standards and specifications. These substandard items termed by the Department of Energy (DOE) as S/CI, pose immediate and potential threats to the safety of DOE and contractor workers, the public, and the environment. Failure of certain systems and processes caused by an S/CI could also have national security implications at Los Alamos National Laboratory (LANL). Nuclear Safety Rules (federal Laws), DOE Orders, and other regulations set forth requirements for DOE contractors to implement effective controls to assure that items and services meet specified requirements. This includes techniques to implement and thereby minimizing the potential threat of entry of S/CI to LANL. As a qualified supplier of goods or services to the LANL, your company will be required to establish and maintain effective controls to prevent the introduction of S/CI to LANL. This will require that your company warrant that all items (including their subassemblies, components, and parts) sold to LANL are genuine (i.e. not counterfeit), new, and unused, and conform to the requirements of the LANL purchase orders/contracts unless otherwise approved in writing to the Los Alamos National Security (LANS) contract administrator

    Nurses' knowledge of pressure ulcer (PU) prevention and management is an important first step in the provision of optimal care. To evaluate PU prevention/risk, staging, and wound description knowledge, a descriptive, cross-sectional survey was conducted among nurses working in an acute care Turkish hospital. The survey instrument was a modified and translated version of the Pieper Pressure Ulcer Knowledge Test (PUKT), and its validity and reliability were established. Nurses completed a Personal Characteristics Form, including sociodemographic information and exposure to educational presentations and information about and experience with PUs, followed by the 49-item modified PUKT which includes 33 prevention/risk items, 9 staging items, and 7 wound description items. All items are true/false questions with an I don't know option (scoring: minimum 0, maximum 49). Correct answers received 1 point and incorrect/unknown answers received 0 points. The paper-pencil questionnaires were distributed by 2 researchers to all nurses in the participating hospital and completed by those willing to be included. Responses were analyzed using descriptive statistics. Pearson's correlation test was used to examine the relationship between quantitative variables, and mean scores were compared using the Mann-Whitney U and Kruskal-Wallis tests. Among the 308 participating nurses (mean age 29.5 ± 8.1 [range 19-56] years) most were women (257, 83.4%) with 7.3 ± 7.8 (range 1-36) years of experience. The mean knowledge score for the entire sample was 29.7 ± 6.7 (range 8-42). The overall percentage of correct answers was 60.6% to 61.8% for PU prevention/risk assessment, 60% for wound description, and 56.6% for PU staging. Knowledge scores were significantly (P <.05) higher for participants who attended at least 1 lecture/conference/course on PUs in the last year, read articles/books about PUs, cared for patients with PUs, or believed their patients were at risk for PU development. Most

  19. Losing Items in the Psychogeriatric Nursing Home

    Directory of Open Access Journals (Sweden)

    J. van Hoof PhD

    2016-09-01

    Full Text Available Introduction: Losing items is a time-consuming occurrence in nursing homes that is ill described. An explorative study was conducted to investigate which items got lost by nursing home residents, and how this affects the residents and family caregivers. Method: Semi-structured interviews and card sorting tasks were conducted with 12 residents with early-stage dementia and 12 family caregivers. Thematic analysis was applied to the outcomes of the sessions. Results: The participants stated that numerous personal items and assistive devices get lost in the nursing home environment, which had various emotional, practical, and financial implications. Significant amounts of time are spent on trying to find items, varying from 1 hr up to a couple of weeks. Numerous potential solutions were identified by the interviewees. Discussion: Losing items often goes together with limitations to the participation of residents. Many family caregivers are reluctant to replace lost items, as these items may get lost again.

  20. Is a Single-Item Operative Performance Rating Sufficient?

    Science.gov (United States)

    Williams, Reed G; Verhulst, Steven; Mellinger, John D; Dunnington, Gary L

    2015-01-01

    A valid measure of resident operative performance ability requires direct observation and accurate rating of multiple resident performances under the normal range of operating conditions. The challenge is to create an operative performance rating (OPR) system that: is easy to use, encourages completion of many ratings immediately after performances and minimally disrupts supervising surgeons' work days. The purpose of this study was to determine whether a score based on a single-item overall OPR provides a valid and stable appraisal of resident operative performances. A retrospective comparison of a single-item OPR with a gold-standard rating based on multiple procedure-specific and general OPR items. Data were collected in the general surgery residency program at Southern Illinois University from 2001 through 2012. Assessments of 1033 operative performances (3 common procedures, 2 laparoscopic, and 1 open) by general surgery residents were collected. OPRs based on single-item overall performance scale scores were compared with gold-standard ratings for the same performances. Differences in performance scores using the 2 scales averaged 0.02 points (5-point scale). Correlations of the single-item and gold-standard scale scores averaged 0.95. Based on generalizability analyses of laparoscopic cholecystectomy ratings, each instrument required 5 observations to achieve reliabilities of 0.80 and 11 observations to achieve reliabilities of 0.90. Only 4.4% of single-item ratings misclassified the performance when compared with the gold-standard rating and all misclassifications were near misses. For 80% of misclassified ratings, single-item ratings were lower. Single-item operative performance measures produced ratings that were virtually identical to gold-standard scale ratings. Misclassifications occurred infrequently and were minor in magnitude. Ratings using the single-item scale: take less time to complete, should increase the sample of procedures rated, and

  2. A description of a staff development program: Preparing the elementary school classroom teacher to lead environmental field trips and to use an integrated subject approach to environmental education

    Science.gov (United States)

    Egana, John Joseph

    This study of the Field Trip Specialist Program (FTS) described how a professional development plan fostered change in the traditional roles of third and fourth grade teachers. Teachers that volunteered were prepared to become interpretive guides for their class on environmental field trips, integrate their basic subject areas lessons into an environmental science context, and develop their self-perception as professional educators. This qualitative study made use of quantitative data and drew on information collected over four years from surveys, interviews, classroom observations, field trip and workshop observations, focus groups, journals and assessments performed in Florida. The FTS Program attracted teachers who thought it was important for all students to understand environmental issues, and these teachers believed in integrated instruction. These beliefs were inconsistent with many aspects of school culture. FTS invited the participation of these teachers and encouraged them to take control of the program by serving as instructors and program developers. Teachers described themselves as prepared to deliver the FTS Program with a high level of motivation and relevance. They also credited the program as beneficial in preparation for the Florida Comprehensive Assessment Tests (FCAT). Teachers reported that their responsibility as field trip leaders was the primary factor motivating them to provide conscientious presentation of pre- and post-field trip lessons and thorough integration of environmental topics in basic subject area instruction. Despite the impact of the field trip leadership factor, I could not find another program in the State of Florida that required teachers to lead their own field trips. Other influential factors specific to this program were: Voluntary participation, on-site field instruction, peer instructors and program developers, high quality and task specific materials, and pre- and post-assessments for students. Factors were identified

    This article summarizes the 5-year effort of a preengineering program to improve the recruitment and retention of underrepresented college students to pursue careers in science, mathematics, engineering, and technology (SMET) at The University of Akron. The purpose of this study is to assess The University of Akron's successful operation of the special high school Upward Bound and preengineering Academic Achievement Programs to increase the number of underrepresented students in SMET. The programs are in collaboration with the College of Engineering's Minority Engineering Program, Increasing Diversity in Engineering Academics. The effectiveness of the programs is measured using the following parameters: (1) average high school grade point average before and after participating in preengineering programs, (2) high school math and science achievement, (3) retention rate for students returning from the previous year, and (4) percentage of students committed to SMET upon graduation. The end results of using these strategies are that the targeted students, who have expressed an interest in mathematics and science, are highly motivated and excited about exploring SMET.

    2016-02-01

    This article describes and presents outcomes of a home-based, self-administered version of the Enhanced Natural Gestures (ENG) program for individuals with Angelman syndrome. Parents of 18 individuals (11 boys and 7 girls) with Angelman syndrome, in consultation with their speech-language pathologists, participated in a quasi-experimental "B" design in which they self-administered an instructional program to teach their children to use enhanced natural gestures at home and/or in the community. Parents integrated 2 teaching methods, Mand-Model with time delay and Molding-Shaping, into their everyday interactions with their children. Parents reported outcomes of the program through goal attainment scaling and completion of the ENG Acceptability Rating Form. Children's overall achievements acquiring ENGs generally met or exceeded program (and parent) expectations. Most parents reported little difficulty self-administering the ENG program with their children and regarded the program positively across multiple dimensions. ENGs may, in conjunction with other forms of augmentative and alternative communication, represent a viable method of communication for many individuals with Angelman syndrome. Further research is warranted to explore the feasibility of ENGs with other populations of individuals with severe disabilities and complex communication challenges.

    Full Text Available Abstract Background Sustainable lifestyle modification strategies are needed to address obesity and cardiovascular risk factors. Intensive, individualised programs have been successful, but are limited by time and resources. We have formulated a group-based lifestyle education program based upon national diet and physical activity (PA recommendations to manage obesity and cardio-metabolic risk factors. This article describes the content and delivery of this program, with information on compliance and acceptability. Methods Overweight/obese adults (n = 153 with metabolic syndrome were recruited from the community and randomly allocated to intervention (INT or control (CON. Written copies of Australian national dietary and PA guidelines were provided to all participants. INT took part in a 16-week lifestyle program which provided a curriculum and practical strategies on 1 dietary and PA information based on national guidelines, 2 behavioural self-management tools, 3 food-label reading, supermarkets tour and cooking, 4 exercise sessions, and 5 peer-group support. Compliance was assessed using attendance records and weekly food/PA logs. Participants' motivations, perceived benefits and goals were assessed through facilitated discussion. Program acceptability feedback was collected through structured focus groups. Results Although completion of weekly food/PA records was poor, attendance at information/education sessions (77% overall and exercise participation (66% overall was high, and compared with CON, multiple markers of body composition and cardio-metabolic health improved in INT. Participants reported that the most useful program components included food-label reading, cooking sessions, and learning new and different physical exercises, including home-based options. Participants also reported finding self-management techniques helpful, namely problem solving and short-term goal setting. The use of a group setting and supportive 'peer' leaders

  8. From concepts to lexical items.

    Bierwisch, M; Schreuder, R

    1992-03-01

    In this paper we address the question how in language production conceptual structures are mapped onto lexical items. First we describe the lexical system in a fairly abstract way. Such a system consists of, among other things, a fixed set of basic lexical entries characterized by four groups of information: phonetic form, grammatical features, argument structure, and semantic form. A crucial assumption of the paper is that the meaning in a lexical entry has a complex internal structure composed of more primitive elements (decomposition). Some aspects of argument structure and semantic form and their interaction are discussed with respect to the issue of synonymy. We propose two different mappings involved in lexical access. One maps conceptual structures to semantic forms, and the other maps semantic forms to conceptual structures. Both mappings are context dependent and are many-to-many mappings. We present an elaboration of Levelt's (1989) model in which these processes interact with the grammatical encoder and the mental lexicon. Then we address the consequences of decomposition for processing models, especially the nature of the input of lexical access and the time course. Processing models that use the activation metaphor may have difficulties accounting for certain phenomena where a certain lemma triggers not one, but two or more word forms that have to be produced with other word forms in between.

    Summary Introduction. Different series emphasized the necessity of rehabilitation program after infiltration of platelet-rich plasma (PRP) in case of tendinopathy. However, most of them describe only briefly the reeducation protocol and these programs vary. Our aim was to extensively describe a specific standardized rehabilitation program. Methods. After a review of literature of post-PRP infiltration protocols, we had developed a standardized rehabilitation protocol. This protocol was evaluated by 30 subjects with chronic jumper’s knee who. A standardised progressive sub-maximal eccentric program supervised by a physical therapist for 6 weeks was started 1 week post-infiltration. The patient benefited also from electromyostimulation, isometric strengthening and stretching of the quadriceps, cycloergometer and cryotherapy. After the supervised program, the patient had to make an auto-reeducation added to the reathletisation protocol for 6 more weeks which was followed by maintenance exercises up to 1 year. The assessments were made using a VAS, IKDC and VISA-P scores. Results. The VAS, IKDC and VISA-P scores decreased very significantly with time. The compliance to auto-reeducation was good. Conclusions. We proposed a simple and efficient protocol based on sub-maximal eccentric reeducation to add to PRP infiltrations in case of patellar tendinopathy. PMID:24932453

    Mentoring plays an important role in learning and career development. Mentored researchers are more productive and more likely to publish their work. However, mentorship programs are not universally used in most settings or disciplines. Furthermore, successful and mutually beneficial mentoring relationships are not always easy to arrange. Long-distance mentoring relationships are even more difficult to handle and may break down for a wide variety of reasons. Drawing from our experiences with the first Canadian Institutes of Health Research - Canadian HIV Trials Network international postdoctoral fellowship program, we describe the roles of the context, the key mentor and the mentee attributes; goals and expectations; environments, local support, a communication plan, funding, face-to-face contact, multidisciplinary collaboration, co-mentoring, and evaluation as they apply to the successful implementation of a long-distance mentoring program.

    We examined young and older adults' ability to flexibly adapt response criterion on a recognition test when the probability that a test item had been studied was cued by test color. One word color signaled that the probability of the test item being old was 70% and a second color signaled that the probability of the test item being new was 70%. Young and older adults demonstrated similar levels of criterion shifting in response to color cues. Moreover, although both young and older adults were slowed when test-item color incorrectly predicted test-item status, the extent of slowing did not differ across age group. Putative measures of cognitive control predicted recognition accuracy but not the degree to which criterion changed with test-item color. These results suggest that adaptive criterion shifting does not tax cognitive control or, if it does require effort, may be no more onerous for older than for young adults.

    Dietary and physical activity habits are developed early in life and are influenced by family environments. We describe and evaluate an intervention for low-income families to encourage healthy habits. The RD Parent Empowerment Program (http://www.eatright.org/programs/kidseatright/activities/content.aspx?id=6442477891) consists of four workshops centered on the 8 Habits of Healthy Children and Families (Academy of Nutrition and Dietetics Foundation). Registered dietitian nutritionists conduct the workshops in school and community settings using a structured leader guide and tailor the communication and interactive activities to the audience. Participants are parents of young children. Our goals were to use a phenomenologic approach to elicit participant feedback, determine whether participants in the RD Parent Empowerment Program made healthier choices for their families after attending the workshops, and identify which elements of the program participants believed contributed most to its success. The evaluation design used a pragmatic, mixed-methods approach utilizing postintervention focus groups and pre-post intervention scores on the Family Nutrition and Physical Activity (FNPA) survey. All workshop attendees aged 18 years or older were eligible to participate in the evaluation. One hundred twenty-three parents participated in the intervention across seven sites. Focus group results were analyzed using thematic analysis methods to match themes to the main intervention goals. t Tests were used to compare pre- and postintervention FNPA scores and demographic characteristics pooled across sites. FNPA scores significantly improved from pre- to postintervention by a mean of 4.3 FNPA points (6.5%; PParent Empowerment Program generates meaningful self-reported behavior change in parents. Long-term sustainability of the changes must be investigated. Copyright © 2014 Academy of Nutrition and Dietetics. Published by Elsevier Inc. All rights reserved.

    Observational evidence from behavioral weight control trials and community studies suggests that greater frequency of weighing oneself, or tracking weight, is associated with better weight outcomes. Conversely, it has also been suggested that frequent weight tracking may have a negative impact on mental health and outcomes during weight loss, but there are minimal experimental data that address this concern in the context of an active weight loss program. To achieve the long-term goal of strengthening behavioral weight loss programs, the purpose of this randomized controlled trial (the Tracking Study) is to test variations on frequency of self-weighing during a behavioral weight loss program, and to examine psychosocial and mental health correlates of weight tracking and weight loss outcomes. This paper describes the study design, intervention features, recruitment, and baseline characteristics of participants enrolled in the Tracking Study. Three hundred thirty-nine overweight and obese adults were recruited and randomized to one of three variations on weight tracking frequency during a 12-month weight loss program with a 12-month follow-up: daily weight tracking, weekly weight tracking, or no weight tracking. The primary outcome is weight in kilograms at 24 months. The weight loss program integrates each weight tracking instruction with standard behavioral weight loss techniques (goal setting, self-monitoring, stimulus control, dietary and physical activity enhancements, lifestyle modifications); participants in weight tracking conditions were provided with wireless Internet technology (wi-fi-enabled digital scales and touchscreen personal devices) to facilitate weight tracking during the study. This study was successful in recruiting adult male and female participants and is positioned to enhance the standard of care with regard to weight tracking recommendations.

    The nation's veterinary colleges lack the curricula necessary to meet veterinary demands for animal/public health and emergency preparedness. To this end, the authors report a literature review summarizing training programs within human/veterinary medicine. In addition, the authors describe new competency-based Veterinary Credential Responder training at North Carolina State University College of Veterinary Medicine (NCSU CVM). From an evaluation of 257 PubMed-derived articles relating to veterinary/medical disaster training, 14 fulfilled all inclusion requirements (nine were veterinary oriented; five came from human medical programs). Few offered ideas on the core competencies required to produce disaster-planning and response professionals. The lack of published literature in this area points to a need for more formal discussion and research on core competencies. Non-veterinary articles emphasized learning objectives, commonly listing an incident command system, the National Incident Management System, teamwork, communications, and critical event management/problem solving. These learning objectives were accomplished either through short-course formats or via their integration into a larger curriculum. Formal disaster training in veterinary medicine mostly occurs within existing public health courses. Much of the literature focuses on changing academia to meet current and future needs in public/animal health disaster-preparedness and careers. The NCSU CVM program, in collaboration with North Carolina Department of Agriculture and Consumer Service, Emergency Programs and University of North Carolina at Chapel Hill School of Public Health, operates as a stand-alone third-year two-week core-curriculum training program that combines lecture, online, experiential, and group exercises to meet entry-level federal credentialing requirements.

    Full Text Available Abstract Background Multi attribute utility (MAU instruments are used to include the health related quality of life (HRQoL in economic evaluations of health programs. Comparative studies suggest different MAU instruments measure related but different constructs. The objective of this paper is to describe the methods employed to achieve content validity in the descriptive system of the Assessment of Quality of Life (AQoL-6D, MAU instrument. Methods The AQoL program introduced the use of psychometric methods in the construction of health related MAU instruments. To develop the AQoL-6D we selected 112 items from previous research, focus groups and expert judgment and administered them to 316 members of the public and 302 hospital patients. The search for content validity across a broad spectrum of health states required both formative and reflective modelling. We employed Exploratory Factor Analysis and Structural Equation Modelling (SEM to meet these dual requirements. Results and Discussion The resulting instrument employs 20 items in a multi-tier descriptive system. Latent dimension variables achieve sensitive descriptions of 6 dimensions which, in turn, combine to form a single latent QoL variable. Diagnostic statistics from the SEM analysis are exceptionally good and confirm the hypothesised structure of the model. Conclusions The AQoL-6D descriptive system has good psychometric properties. They imply that the instrument has achieved construct validity and provides a sensitive description of HRQoL. This means that it may be used with confidence for measuring health related quality of life and that it is a suitable basis for modelling utilities for inclusion in the economic evaluation of health programs.

Mentored researchers are more productive and more likely to publish their work. However, mentorship programs are not universally used in most settings or disciplines. Furthermore, successful and mutually beneficial mentoring relationships are not always easy to arrange. Long-distance mentoring relationships are even more difficult to handle and may break down for a wide variety of reasons. Drawing from our experiences with the first Canadian Institutes of Health Research – Canadian HIV Trials Network international postdoctoral fellowship program, we describe the roles of the context, the key mentor and the mentee attributes; goals and expectations; environments, local support, a communication plan, funding, face-to-face contact, multidisciplinary collaboration, co-mentoring, and evaluation as they apply to the successful implementation of a long-distance mentoring program.Keywords: long distance, mentoring, framework, Canada, Cameroon

    Four-factor structure of the two 8-item short forms of Child Perceptions Questionnaire CPQ11-14 (RSF:8 and ISF:8) has been confirmed. However, the sum scores are typically reported in practice as a proxy of Oral health-related Quality of Life (OHRQoL), which implied a unidimensional structure. This study first assessed the unidimensionality of 8-item short forms of CPQ11-14. Item response theory (IRT) was employed to offer an alternative and complementary approach of validation and to overcome the limitations of classical test theory assumptions. A random sample of 649 12-year-old school children in Hong Kong was analyzed. Unidimensionality of the scale was tested by confirmatory factor analysis (CFA), principle component analysis (PCA) and local dependency (LD) statistic. Graded response model was fitted to the data. Contribution of each item to the scale was assessed by item information function (IIF). Reliability of the scale was assessed by test information function (TIF). Differential item functioning (DIF) across gender was identified by Wald test and expected score functions. Both CPQ11-14 RSF:8 and ISF:8 did not deviate much from the unidimensionality assumption. Results from CFA indicated acceptable fit of the one-factor model. PCA indicated that the first principle component explained >30 % of the total variation with high factor loadings for both RSF:8 and ISF:8. Almost all LD statistic dependency. Flat and low IIFs were observed in the oral symptoms items suggesting little contribution of information to the scale and item removal caused little practical impact. Comparing the TIFs, RSF:8 showed slightly better information than ISF:8. In addition to oral symptoms items, the item "Concerned with what other people think" demonstrated a uniform DIF (p < 0.001). The expected score functions were not much different between boys and girls. Items related to oral symptoms were not informative to OHRQoL and deletion of these items is suggested. The impact of

    1995-12-01

    Recently in this journal Peters and Murphy challenged the validity of factor analyses done on bimodal handedness data, suggesting instead that right- and left-handers be studied separately. But bimodality may be avoidable if attention is paid to Oldfield's questionnaire format and instructions for the subjects. Two characteristics appear crucial: a two-column LEFT-RIGHT format for the body of the instrument and what we call Oldfield's Admonition: not to indicate strong preference for handedness item, such as write, unless "... the preference is so strong that you would never try to use the other hand unless absolutely forced to...". Attaining unimodality of an item distribution would seem to overcome the objections of Peters and Murphy. In a 1984 survey in Boston we used Oldfield's ten-item questionnaire exactly as published. This produced unimodal item distributions. With reflection of the five-point item scale and a logarithmic transformation, we achieved a degree of normalization for the items. Two surveys elsewhere based on Oldfield's 20-item list but with changes in the questionnaire format and the instructions, yielded markedly different item distributions with peaks at each extreme and sometimes in the middle as well.

  18. Exploratory Item Classification Via Spectral Graph Clustering.

    2017-01-01

    Large-scale assessments are supported by a large item pool. An important task in test development is to assign items into scales that measure different characteristics of individuals, and a popular approach is cluster analysis of items. Classical methods in cluster analysis, such as the hierarchical clustering, K-means method, and latent-class analysis, often induce a high computational overhead and have difficulty handling missing data, especially in the presence of high-dimensional responses. In this article, the authors propose a spectral clustering algorithm for exploratory item cluster analysis. The method is computationally efficient, effective for data with missing or incomplete responses, easy to implement, and often outperforms traditional clustering algorithms in the context of high dimensionality. The spectral clustering algorithm is based on graph theory, a branch of mathematics that studies the properties of graphs. The algorithm first constructs a graph of items, characterizing the similarity structure among items. It then extracts item clusters based on the graphical structure, grouping similar items together. The proposed method is evaluated through simulations and an application to the revised Eysenck Personality Questionnaire.

  19. Item and order memory for novel visual patterns assessed by two-choice recognition.

    Avons, S E; Ward, Geoff; Melling, Lindsay

    2004-07-01

    Five experiments examined item and order memory for short lists of novel visual patterns. Memory was tested either by an item recognition test, choosing between a target and a similar foil (Experiments 1, 3a, and 4), or by a relative recency decision between two patterns that occupied adjacent list positions (Experiments 2, 3b, and 5). For both item recognition and relative recency tasks, accuracy was in most cases constant across serial positions, except for a recency advantage that was usually restricted to the most recent item or recency decision. Only a small and marginally significant effect of list length was observed for item recognition. Relative recency was more sensitive to list length and fell to near-chance levels with lists of eight items. We conclude that for these materials, prerecency item recognition depends on stable, context-free descriptions of items. Relative recency judgements are sensitive to list properties, but fail to show evidence of primacy or extended recency that are observed when other techniques are used to study serial order memory. We discuss the results in relation to four current models of serial order memory that embody different assumptions in the way that serial order is represented.

    There is not a single universally accepted activity of daily living (ADL) instrument available to compare disability assessments across different patient groups. We developed a generic item bank of ADL items using item response theory, the Academic Medical Center Linear Disability Scale (ALDS). When comparing outcomes of the ALDS between patients groups, item characteristics of the ALDS should be comparable across groups. The aim of the study was to assess the differential item functioning (DIF) in a group of patients with various disorders to investigate the comparability across these groups. Cross-sectional, multicenter study including 1,283 in- and outpatients with a variety of disorders and disability levels. The sample was divided in two groups: (1) mainly neurological patients (n=497; vascular medicine, Parkinson's disease and neuromuscular disorders) and (2) patients from internal medicine (n=786; pulmonary diseases, chronic pain, rheumatoid arthritis, and geriatric patients). Eighteen of 72 ALDS items showed statistically significant DIF (P<0.01). However, the DIF could effectively be modeled by the introduction of disease-specific parameters. In the subgroups studied, DIF could be modeled in such a way that the ensemble of the items comprised a scale applicable in both groups.

  3. Effects of spacing of item repetitions in continuous recognition memory: does item retrieval difficulty promote item retention in older adults?

    2013-01-01

    BACKGROUND/STUDY CONTEXT: Older adults exhibit an age-related deficit in item memory as a function of the length of the retention interval, but older adults and young adults usually show roughly equivalent benefits due to the spacing of item repetitions in continuous memory tasks. The current experiment investigates the seemingly paradoxical effects of retention interval and spacing in young and older adults using a continuous recognition memory procedure. Fifty young adults and 52 older adults gave memory confidence ratings to words that were presented once (P1), twice (P2), or three times (P3), and the effects of the lag length and retention interval were assessed at P2 and at P3, respectively. Response times at P2 were disproportionately longer for older adults than for younger adults as a function of the number of items occurring between P1 and P2, suggestive of age-related loss in item memory. Ratings of confidence in memory responses revealed that older adults remembered fewer items at P2 with a high degree of certainty. Confidence ratings given at P3 suggested that young and older adults derived equivalent benefits from the spacing between P1 and P2. Findings of this study support theoretical accounts that suggest that recursive reminding and/or item retrieval difficulty promote item retention in older adults.

    Nunes, Sandra; Oliveira, Teresa; Oliveira, Amílcar

    2017-07-01

    The Item Response Theory (IRT) has become one of the most popular scoring frameworks for measurement data, frequently used in computerized adaptive testing, cognitively diagnostic assessment and test equating. According to Andrade et al. (2000), IRT can be defined as a set of mathematical models (Item Response Models - IRM) constructed to represent the probability of an individual giving the right answer to an item of a particular test. The number of Item Responsible Models available to measurement analysis has increased considerably in the last fifteen years due to increasing computer power and due to a demand for accuracy and more meaningful inferences grounded in complex data. The developments in modeling with Item Response Theory were related with developments in estimation theory, most remarkably Bayesian estimation with Markov chain Monte Carlo algorithms (Patz & Junker, 1999). The popularity of Item Response Theory has also implied numerous overviews in books and journals, and many connections between IRT and other statistical estimation procedures, such as factor analysis and structural equation modeling, have been made repeatedly (Van der Lindem & Hambleton, 1997). As stated before the Item Response Theory covers a variety of measurement models, ranging from basic one-dimensional models for dichotomously and polytomously scored items and their multidimensional analogues to models that incorporate information about cognitive sub-processes which influence the overall item response process. The aim of this work is to introduce the main concepts associated with one-dimensional models of Item Response Theory, to specify the logistic models with one, two and three parameters, to discuss some properties of these models and to present the main estimation procedures.

    The ''Yucca Mountain Site Description'' summarizes, in a single document, the current state of knowledge and understanding of the natural system at Yucca Mountain. It describes the geology; geochemistry; past, present, and projected future climate; regional hydrologic system; and flow and transport within the unsaturated and saturated zones at the site. In addition, it discusses factors affecting radionuclide transport, the effect of thermal loading on the natural system, and tectonic hazards. The ''Yucca Mountain Site Description'' is broad in nature. It summarizes investigations carried out as part of the Yucca Mountain Project since 1988, but it also includes work done at the site in earlier years, as well as studies performed by others. The document has been prepared under the Office of Civilian Radioactive Waste Management quality assurance program for the Yucca Mountain Project. Yucca Mountain is located in Nye County in southern Nevada. The site lies in the north-central part of the Basin and Range physiographic province, within the northernmost subprovince commonly referred to as the Great Basin. The basin and range physiography reflects the extensional tectonic regime that has affected the region during the middle and late Cenozoic Era. Yucca Mountain was initially selected for characterization, in part, because of its thick unsaturated zone, its arid to semiarid climate, and the existence of a rock type that would support excavation of stable openings. In 1987, the United States Congress directed that Yucca Mountain be the only site characterized to evaluate its suitability for development of a geologic repository for high-level radioactive waste and spent nuclear fuel.

    Mueller, Evelyn A; Bengel, Juergen; Wirtz, Markus A

    2013-12-01

    This study aimed to develop a self-description assessment instrument to measure work performance in patients with musculoskeletal diseases. In terms of the International Classification of Functioning, Disability and Health (ICF), work performance is defined as the degree of meeting the work demands (activities) at the actual workplace (environment). To account for the fact that work performance depends on the work demands of the job, we strived to develop item banks that allow a flexible use of item subgroups depending on the specific work demands of the patients' jobs. Item development included the collection of work tasks from literature and content validation through expert surveys and patient interviews. The resulting 122 items were answered by 621 patients with musculoskeletal diseases. Exploratory factor analysis to ascertain dimensionality and Rasch analysis (partial credit model) for each of the resulting dimensions were performed. Exploratory factor analysis resulted in four dimensions, and subsequent Rasch analysis led to the following item banks: 'impaired productivity' (15 items), 'impaired cognitive performance' (18), 'impaired coping with stress' (13) and 'impaired physical performance' (low physical workload 20 items, high physical workload 10 items). The item banks exhibited person separation indices (reliability) between 0.89 and 0.96. The assessment of work performance adds the activities component to the more commonly employed participation component of the ICF-model. The four item banks can be adapted to specific jobs where necessary without losing comparability of person measures, as the item banks are based on Rasch analysis.

    The disclosure of widespread sexual abuse committed by professional educators and clergymen in institutions in Germany ignited a national political debate, in which special attention was paid to church-run institutions. We wanted to find out whether the nature of the abuse and its effect on victims differed depending on whether the abuse had been experienced in religiously affiliated versus secular institutions. In 2010, the German government established a hotline that victims could contact anonymously to describe their experiences of sexual abuse. The information provided by callers was documented and categorized. Our analysis looked at a subset of the data collected, in order to compare the nature of the abuse experienced at three types of institutions: Roman Catholic, Protestant, and non-religiously affiliated. Non-parametric tests were used to compare frequency distributions, and qualitative data were analyzed descriptively. Of the 1050 victims in our sample, 404 had been in Roman Catholic, 130 in Protestant, and 516 in non-religious institutions. The overall mean age at the time of reporting was 52.2 years. Males (59.8%) outnumbered females. Victims who had been in religiously affiliated institutions were significantly older than those who had been in secular institutions. Almost half the victims had been abused physically as well as sexually, and most victims reported that the abuse had occurred repeatedly and that the assaults had been committed by males. Patterns of abuse (time, type, and extent), and the gender of the offenders did not differ between the three groups. Intercourse was more frequently reported by older victims and by females. Similar percentages of victims in all groups reported current psychiatric diagnoses (depression, anxiety disorders, PTSD). Significantly more victims from Protestant institutions reported having current psychosocial problems. The results suggest that child sexual abuse in institutions is attributable to the nature of

    Low levels of symptom recognition by staff have been "gateway" barriers to the management of depression in long-term care. The study aims were to refine a depression training program for front-line staff in long-term care and provide evaluative knowledge outcome data. Three primary training modules provide an overview of depression symptoms; a review of causes and situational and environmental contributing factors; and communication strategies, medications, and clinical treatment strategies. McNemar's chi-square tests and paired t-tests were used to examine change in knowledge. Data were analyzed for up to 143 staff members, the majority from nursing.

    The RCP01 Monte Carlo program is used to analyze many geometries of interest in nuclear design and analysis of light water moderated reactors such as the core in its pressure vessel with complex piping arrangement, fuel storage arrays, shipping and container arrangements, and neutron detector configurations. Written in FORTRAN and in use on a variety of computers, it is capable of estimating steady state neutron or photon reaction rates and neutron multiplication factors. The energy range covered in neutron calculations is that relevant to the fission process and subsequent slowing-down and thermalization, i.e., 20 MeV to 0 eV. The same energy range is covered for photon calculations.

    Teleology descriptions capture the purpose of an entity, mechanism, or activity with which they are associated. These descriptions can be used in explanation, diagnosis, and design reuse. We describe a technique for acquiring teleological descriptions expressed in the teleology language TeD. Acquisition occurs during design by observing design modifications and design verification. We demonstrate the acquisition technique in an electronic circuit design.

    The Patient-Reported Outcomes Measurement Information System (PROMIS(®)) is a new, state-of-the-art assessment system for measuring patient-reported health and well-being of adults and children that has the potential to be more valid, reliable and responsive than existing PROMs. The PROMIS items can be administered in short forms or, more efficiently, through computerized adaptive testing. This paper describes the translation of 563 items from 17 PROMIS item banks (domains) for adults from the English source into Dutch-Flemish. The translation was performed by FACITtrans using standardized methodology and approved by the PROMIS Statistical Center. The translation included four forward translations, two back-translations, three to five independent reviews (at least two Dutch, one Flemish) and pre-testing in 70 adults (age range 20-77) from the Netherlands and Flanders. A small number of items required separate translations for Dutch and Flemish: physical function (five items), pain behaviour (two items), pain interference (one item), social isolation (one item) and global health (one item). Challenges faced in the translation process included: scarcity or overabundance of possible translations, unclear item descriptions, constructs broader/smaller in the target language, difficulties in rank ordering items, differences in unit of measurement, irrelevant items or differences in performance of activities. By addressing these challenges, acceptable translations were obtained for all items. The methodology used and experience gained in this study can be used as an example for researchers in other countries interested in translating PROMIS. The Dutch-Flemish PROMIS items are linguistically equivalent. Short forms will soon be available for use and entire item banks are ready for cross-cultural validation in the Netherlands and Flanders.

    Full Text Available ​ Background and Objectives: In all health systems, maternity health program has an important role for its great effects. Therefore, the evaluation of this program constantly was at the center of attention of managers and policy makers. The current study aimed to analyze maternity health program by focusing on the evaluation process according to the evaluation comprehensive model (CIPPI in East Azarbaijan. Material and Methods: This is a descriptive cross-sectional study and its data were collected by qualitative methods such as observing and interviewing. By evaluating different levels of delivered services, interviewing process owners and customers and reviewing the documents, evaluation process was studied and the results were compared with CIPPI model. Results: The yielded results from the comparison of this program with CIPPI model indicated that from 24 analyzed items in 5 dimensions of this program, only 5 items were measured completely, 5 items measured partially and 14 items were not measured at all. There were other problems including weaknesses in checklist, standards and during the process of evaluation. Conclusion: According to the results, it is concluded that the current model of maternity health evaluation program in Eastern Azarbaijan has a notable gap with an ideal evaluation program and the need for a revise of this program according to efficient and effective evaluation models seems necessary.

  7. Item response theory for measurement validity.

    Yang, Frances M; Kao, Solon T

    2014-06-01

    Item response theory (IRT) is an important method of assessing the validity of measurement scales that is underutilized in the field of psychiatry. IRT describes the relationship between a latent trait (e.g., the construct that the scale proposes to assess), the properties of the items in the scale, and respondents' answers to the individual items. This paper introduces the basic premise, assumptions, and methods of IRT. To help explain these concepts we generate a hypothetical scale using three items from a modified, binary (yes/no) response version of the Center for Epidemiological Studies-Depression scale that was administered to 19,399 respondents. We first conducted a factor analysis to confirm the unidimensionality of the three items and then proceeded with Mplus software to construct the 2-Parameter Logic (2-PL) IRT model of the data, a method which allows for estimates of both item discrimination and item difficulty. The utility of this information both for clinical purposes and for scale construction purposes is discussed.

    We investigate short-term learning from hints and feedback in a Web-based physics tutoring system. Both the skill of students and the difficulty and discrimination of items were determined by applying item response theory (IRT) to the first answers of students who are working on for-credit homework items in an introductory Newtonian physics course. We show that after tutoring a shifted logistic item response function with lower discrimination fits the students’ second responses to an item previously answered incorrectly. Student skill decreased by 1.0 standard deviation when students used no tutoring between their (incorrect) first and second attempts, which we attribute to “item-wrong bias.” On average, using hints or feedback increased students’ skill by 0.8 standard deviation. A skill increase of 1.9 standard deviation was observed when hints were requested after viewing, but prior to attempting to answer, a particular item. The skill changes measured in this way will enable the use of IRT to assess students based on their second attempt in a tutoring environment.

    Full Text Available Abstract Background The community’s awareness of Tuberculosis (TB and delays in health care seeking remain important issues in Indonesia despite the extensive efforts of community-based TB programs delivered by a non-government organisation (NGO. This study explored the knowledge and behaviours in relation to TB and early diagnosis before and after an asset-based intervention designed to improve these issues. Methods Six villages in Flores, Indonesia were purposively selected to participate in this study. Three villages served as intervention villages and the other three villages provided a comparison group. Data collection included interviews, group discussions, observations, field notes and audit of records. Results In total, 50 participants across six villages were interviewed and three group discussions were conducted in the intervention villages supplemented by 1 – 5 h of observation during monthly visits. Overall, participants in all villages had limited knowledge regarding the cause and transmission of TB before the intervention. The delay in health seeking behaviour was mainly influenced by ignorance of TB symptoms. Health care providers also contributed to delayed diagnosis by ignoring the symptoms of TB suspects at the first visit and failing to examine TB suspects with sputum tests. Stigmatisation of TB patients by the community was reported, although this did not seem to be common. Early case detection was less than 50 % in four of the six villages before the asset-based intervention. Knowledge of TB improved after the intervention in the intervention villages alongside improved education activities. Early case detection also increased in the intervention villages following this intervention. The behaviour changes related to prevention of TB were also obvious in the intervention villages but not the comparison group. Conclusion This small project demonstrated that an asset-based intervention can result in positive changes in

    Four levels of hydrologic models have been categorized to handle varying complexities and degrees of available input parameters. The first level is for the simplest one-dimensional models having analytical solutions; the second level includes idealized analytic or hybrid analytic models for single aquifer systems with scanty input data; the third level deals with more complex single or quasi-multilayered systems; and the fourth level is for complex multilayered systems. The three-dimensional finite element ground-water model described in this report falls under the fourth level of hydrologic models. This model is capable of simulating single-layered systems having variable thickness or multilayered systems where not only thickness can be varied, but the number of layers can be changed to agree with the vertical geologic section. Supporting programs have been developed to plot grid values, contour maps and three-dimensional graphics of the input data used in simulation as well as the results obtained. At present, the model considers only confined aquifers. The capabilities of the model were demonstrated by using a test case consisting of the multilayered ground-water system beneath Long Island, New York.

  11. Elaborate Item Count Questioning: Why Do People Underreport in Item Count Responses?

    Directory of Open Access Journals (Sweden)

    Takahiro Tsuchiya

    2010-12-01

    Full Text Available The item count technique, used often to investigate illegal or socially undesirable behaviours, requires respondents to indicate merely the number of applicable items from among a list. However, the number of applicable items indicated via the item count question tends to be smaller than when it is calculated from the direct `applies/does not apply' responses to each item. Because this inconsistency, which we refer to as the underreporting effect, often disturbs proper item count estimates, the causes of this effect are explored in this paper. Web survey results revealed that the order of the response alternatives is irrelevant to the underreporting effect, and that the underreporting effect is caused by the response format in which the item count question requests merely the number of applicable items and not the number of non-applicable items. It is also shown that the magnitude of the underreporting effect decreases when the respondents are asked to indicate the numbers of both applicable and non-applicable items, which we refer to as elaborate item count questioning.

    Numerous tools and individual items have been proposed to assess the methodological quality of randomized controlled trials (RCTs). The frequency of use of these items varies according to health area, which suggests a lack of agreement regarding their relevance to trial quality or risk of bias. The objectives of this study were: (1) to identify the underlying component structure of items and (2) to determine relevant items to evaluate the quality and risk of bias of trials in physical therapy by using an exploratory factor analysis (EFA). A methodological research design was used, and an EFA was performed. Randomized controlled trials used for this study were randomly selected from searches of the Cochrane Database of Systematic Reviews. Two reviewers used 45 items gathered from 7 different quality tools to assess the methodological quality of the RCTs. An exploratory factor analysis was conducted using the principal axis factoring (PAF) method followed by varimax rotation. Principal axis factoring identified 34 items loaded on 9 common factors: (1) selection bias; (2) performance and detection bias; (3) eligibility, intervention details, and description of outcome measures; (4) psychometric properties of the main outcome; (5) contamination and adherence to treatment; (6) attrition bias; (7) data analysis; (8) sample size; and (9) control and placebo adequacy. Because of the exploratory nature of the results, a confirmatory factor analysis is needed to validate this model. To the authors' knowledge, this is the first factor analysis to explore the underlying component items used to evaluate the methodological quality or risk of bias of RCTs in physical therapy. The items and factors represent a starting point for evaluating the methodological quality and risk of bias in physical therapy trials. Empirical evidence of the association among these items with treatment effects and a confirmatory factor analysis of these results are needed to validate these items.

    2014-05-01

    Full Text Available Item response theory (IRT becomes an increasingly important tool when analyzing “big data” gathered from online educational venues. However, the mechanism was originally developed in traditional exam settings, and several of its assumptions are infringed upon when deployed in the online realm. For a large-enrollment physics course for scientists and engineers, the study compares outcomes from IRT analyses of exam and homework data, and then proceeds to investigate the effects of each confounding factor introduced in the online realm. It is found that IRT yields the correct trends for learner ability and meaningful item parameters, yet overall agreement with exam data is moderate. It is also found that learner ability and item discrimination is robust over a wide range with respect to model assumptions and introduced noise. Item difficulty is also robust, but over a narrower range.

  16. Optimal pricing and marketing planning for deteriorating items.

    Directory of Open Access Journals (Sweden)

    Seyed Reza Moosavi Tabatabaei

    Full Text Available Optimal pricing and marketing planning plays an essential role in production decisions on deteriorating items. This paper presents a mathematical model for a three-level supply chain, which includes one producer, one distributor and one retailer. The proposed study considers the production of a deteriorating item where demand is influenced by price, marketing expenditure, quality of product and after-sales service expenditures. The proposed model is formulated as a geometric programming with 5 degrees of difficulty and the problem is solved using the recent advances in optimization techniques. The study is supported by several numerical examples and sensitivity analysis is performed to analyze the effects of the changes in different parameters on the optimal solution. The preliminary results indicate that with the change in parameters influencing on demand, inventory holding, inventory deteriorating and set-up costs change and also significantly affect total revenue.

  17. Investigating the Impact of Item Parameter Drift for Item Response Theory Models with Mixture Distributions

    Directory of Open Access Journals (Sweden)

    Yoon Soo ePark

    2016-02-01

    Full Text Available This study investigates the impact of item parameter drift (IPD on parameter and ability estimation when the underlying measurement model fits a mixture distribution, thereby violating the item invariance property of unidimensional item response theory (IRT models. An empirical study was conducted to demonstrate the occurrence of both IPD and an underlying mixture distribution using real-world data. Twenty-one trended anchor items from the 1999, 2003, and 2007 administrations of Trends in International Mathematics and Science Study (TIMSS were analyzed using unidimensional and mixture IRT models. TIMSS treats trended anchor items as invariant over testing administrations and uses pre-calibrated item parameters based on unidimensional IRT. However, empirical results showed evidence of two latent subgroups with IPD. Results showed changes in the distribution of examinee ability between latent classes over the three administrations. A simulation study was conducted to examine the impact of IPD on the estimation of ability and item parameters, when data have underlying mixture distributions. Simulations used data generated from a mixture IRT model and estimated using unidimensional IRT. Results showed that data reflecting IPD using mixture IRT model led to IPD in the unidimensional IRT model. Changes in the distribution of examinee ability also affected item parameters. Moreover, drift with respect to item discrimination and distribution of examinee ability affected estimates of examinee ability. These findings demonstrate the need to caution and evaluate IPD using a mixture IRT framework to understand its effect on item parameters and examinee ability.

    The City of Baltimore, Maryland, and parts of five surrounding counties obtain their water from Loch Raven and Liberty Reservoirs. A third reservoir, Prettyboy, is used to resupply Loch Raven Reservoir. Management of the watershed conditions for each reservoir is a shared responsibility by agreement among City, County, and State jurisdictions. The most recent (2005) Baltimore Reservoir Watershed Management Agreement (RWMA) called for continued and improved water-quality monitoring in the reservoirs and selected watershed tributaries. The U.S. Geological Survey (USGS) conducted a retrospective review of the effectiveness of monitoring data obtained and analyzed by the RWMA jurisdictions from 1981 through 2007 to help identify possible improvements in the monitoring program to address RWMA water-quality concerns. Long-term water-quality concerns include eutrophication and sedimentation in the reservoirs, and elevated concentrations of (a) nutrients (nitrogen and phosphorus) being transported from the major tributaries to the reservoirs, (b) iron and manganese released from reservoir bed sediments during periods of deep-water anoxia, (c) mercury in higher trophic order game fish in the reservoirs, and (d) bacteria in selected reservoir watershed tributaries. Emerging concerns include elevated concentrations of sodium, chloride, and disinfection by-products (DBPs) in the drinking water from both supply reservoirs. Climate change and variability also could be emerging concerns, affecting seasonal patterns, annual trends, and drought occurrence, which historically have led to declines in reservoir water quality. Monitoring data increasingly have been used to support the development of water-quality models. The most recent (2006) modeling helped establish an annual sediment Total Maximum Daily Load to Loch Raven Reservoir, and instantaneous and 30-day moving average water-quality endpoints for chlorophyll-a (chl-a) and dissolved oxygen (DO) in Loch Raven and Prettyboy

  19. Reflection and Hyper-Programming in Persistent Programming Systems

    Science.gov (United States)

    Kirby, Graham

    2010-06-01

    The work presented in this thesis seeks to improve programmer productivity in the following ways: - by reducing the amount of code that has to be written to construct an application; - by increasing the reliability of the code written; and - by improving the programmer's understanding of the persistent environment in which applications are constructed. Two programming techniques that may be used to pursue these goals in a persistent environment are type-safe linguistic reflection and hyper-programming. The first provides a mechanism by which the programmer can write generators that, when executed, produce new program representations. This allows the specification of programs that are highly generic yet depend in non-trivial ways on the types of the data on which they operate. Genericity promotes software reuse which in turn reduces the amount of new code that has to be written. Hyper-programming allows a source program to contain links to data items in the persistent store. This improves program reliability by allowing certain program checking to be performed earlier than is otherwise possible. It also reduces the amount of code written by permitting direct links to data in the place of textual descriptions. Both techniques contribute to the understanding of the persistent environment through supporting the implementation of store browsing tools and allowing source representations to be associated with all executable programs in the persistent store. This thesis describes in detail the structure of type-safe linguistic reflection and hyper-programming, their benefits in the persistent context, and a suite of programming tools that support reflective programming and hyper-programming. These tools may be used in conjunction to allow reflection over hyper-program representations. The implementation of the tools is described.

    2013-07-01

    The Deterministic, Gated Item Response Theory Model (DGM, Shu, Unpublished Dissertation. The University of North Carolina at Greensboro, 2010) is proposed to identify cheaters who obtain significant score gain on tests due to item exposure/compromise by conditioning on the item status (exposed or unexposed items). A "gated" function is introduced to decompose the observed examinees' performance into two distributions (the true ability distribution determined by examinees' true ability and the cheating distribution determined by examinees' cheating ability). Test cheaters who have score gain due to item exposure are identified through the comparison of the two distributions. Hierarchical Markov Chain Monte Carlo is used as the model's estimation framework. Finally, the model is applied in a real data set to illustrate how the model can be used to identify examinees having pre-knowledge on the exposed items.

    Full Text Available Guessing and item omission may be regarded as risk-taking or risk-avoidance strategies – sex specific adaptations to testing situations. In this article, these phenomena were analysed by (a percentage of omissions by sex, (b negative binomial regression to asses sex differences in the number of omissions, (c c-DIF analysis using IRT-LR test and (d linear regression using item attributes, to assess whether the c-parameter is sex differentiated by the percentage of omits (controlling item difficulty. The data set analysed were from the 2012–2014 Polish lower-secondary schools final exams, comprising tests in maths, language, science and humanities. Contrary to the vast body of literature, boys omitted items slightly more frequently than girls. Possible explanations of this finding – specific to the Polish examination system – were provided. The hypothesis of a higher c-parameter for boys did not find strong support from this study. It was shown that the c-parameter should not only be interpreted as resulting from item non-omission. This supports the modern concept of the c-parameter as a consequence not only of random guessing, but also problem solving, creative guessing or cheating.

  6. Sharing medicine: the candidacy of medicines and other household items for sharing, Dominican Republic.

    Directory of Open Access Journals (Sweden)

    Michael N Dohn

    Full Text Available People share medicines and problems can result from this behavior. Successful interventions to change sharing behavior will require understanding people's motives and purposes for sharing medicines. Better information about how medicines fit into the gifting and reciprocity system could be useful in designing interventions to modify medicine sharing behavior. However, it is uncertain how people situate medicines among other items that might be shared. This investigation is a descriptive study of how people sort medicines and other shareable items.This study in the Dominican Republic examined how a convenience sample (31 people sorted medicines and rated their shareability in relation to other common household items. We used non-metric multidimensional scaling to produce association maps in which the distances between items offer a visual representation of the collective opinion of the participants regarding the relationships among the items. In addition, from a pile sort constrained by four categories of whether sharing or loaning the item was acceptable (on a scale from not shareable to very shareable, we assessed the degree to which the participants rated the medicines as shareable compared to other items. Participants consistently grouped medicines together in all pile sort activities; yet, medicines were mixed with other items when rated by their candidacy to be shared. Compared to the other items, participants had more variability of opinion as to whether medicines should be shared.People think of medicines as a distinct group, suggesting that interventions might be designed to apply to medicines as a group. People's differing opinions as to whether it was appropriate to share medicines imply a degree of uncertainty or ambiguity that health promotion interventions might exploit to alter attitudes and behaviors. These findings have implications for the design of health promotion interventions to impact medicine sharing behavior.

    2011-01-01

    Traditionally, women and minorities have not been fully represented in science and engineering. Numerous studies have attributed these differences to gaps in science achievement as measured by various standardized tests. Rather than describe mean group differences in science achievement across multiple cultures, this study focused on an in-depth item-level analysis across two countries: Spain and the United States. This study investigated eighth-grade gender differences on science items across the two countries. A secondary purpose of the study was to explore the nature of gender differences using the many-faceted Rasch Model as a way to estimate gender DIF. A secondary analysis of data from the Third International Mathematics and Science Study (TIMSS) was used to address three questions: 1) Does gender DIF in science achievement exist? 2) Is there a relationship between gender DIF and characteristics of the science items? 3) Do the relationships between item characteristics and gender DIF in science items replicate across countries. Participants included 7,087 eight grade students from the United States and 3,855 students from Spain who participated in TIMSS. The Facets program (Linacre and Wright, 1992) was used to estimate gender DIF. The results of the analysis indicate that the content of the item seemed to be related to gender DIF. The analysis also suggests that there is a relationship between gender DIF and item format. No pattern of gender DIF related to cognitive demand was found. The general pattern of gender DIF was similar across the two countries used in the analysis. The strength of item-level analysis as opposed to group mean difference analysis is that gender differences can be detected at the item level, even when no mean differences can be detected at the group level.

  11. Ignoring Grounded Description

    Directory of Open Access Journals (Sweden)

    Barney G. Glaser, PhD, Hon. PhD

    2016-12-01

    Full Text Available Why is there so much grounded description? The simplest, direct answer is that to many a researcher this is GT. This view is supported by several factors. It is easy and natural to describe accurately. So slipping into grounded description comes naturally and is ok as GT. Also departmental support for description is strongly supported by perspective and academic rewards and history and routine QDA. Also many researchers and readers of research cannot conceptualize very well if at all. They want accurate description about the data in the study. They are not into taking a core category as a general category applicable to general implications applicable to much data elsewhere. Their study is about explaining processes the data, NOT in studying the implications of core and sub-core categories as they are integrated into an explanatory theory. I trust the reader can think of other sources of letting GT research slip into conceptual description.

  12. Item diagnostics in multivariate discrete data.

    Maydeu-Olivares, Alberto; Liu, Yang

    2015-06-01

    Researchers who evaluate the fit of psychometric models to binary or multinomial items often look at univariate and bivariate residuals to determine how a poorly fitting model can be improved. There is a class of z statistics and also a class of generalized X₂ statistics that can be used for examining these marginal fits. We describe these statistics and compare them with regard to the control of Type I error and statistical power. We show how the class of z statistics can be extended to accommodate items with multinomial response options. We provide guidelines for the use of these statistics, including how to control for multiple testing, and present 2 detailed examples. Using the root mean square error of approximation (RMSEA) for discrete data to adjudge fit, the examples illustrate how the use of these methods can dramatically improve the fit of item response theory models to widely used measures in personality and clinical psychology.

    Bruce, Bonnie; Fries, James; Lingala, Bharathi; Hussain, Yusra Nazar; Krishnan, Eswar

    2013-10-03

    Disability and Physical Function (PF) outcome assessment has had limited ability to measure functional status at the floor (very poor functional abilities) or the ceiling (very high functional abilities). We sought to identify, develop and evaluate new floor and ceiling items to enable broader and more precise assessment of PF outcomes for the NIH Patient-Reported-Outcomes Measurement Information System (PROMIS). We conducted two cross-sectional studies using NIH PROMIS item improvement protocols with expert review, participant survey and focus group methods. In Study 1, respondents with low PF abilities evaluated new floor items, and those with high PF abilities evaluated new ceiling items for clarity, importance and relevance. In Study 2, we compared difficulty ratings of new floor items by low functioning respondents and ceiling items by high functioning respondents to reference PROMIS PF-10 items. We used frequencies, percentages, means and standard deviations to analyze the data. In Study 1, low (n = 84) and high (n = 90) functioning respondents were mostly White, women, 70 years old, with some college, and disability scores of 0.62 and 0.30. More than 90% of the 31 new floor and 31 new ceiling items were rated as clear, important and relevant, leaving 26 ceiling and 30 floor items for Study 2. Low (n = 246) and high (n = 637) functioning Study 2 respondents were mostly White, women, 70 years old, with some college, and Health Assessment Questionnaire (HAQ) scores of 1.62 and 0.003. Compared to difficulty ratings of reference items, ceiling items were rated to be 10% more to greater than 40% more difficult to do, and floor items were rated to be about 12% to nearly 90% less difficult to do. These new floor and ceiling items considerably extend the measurable range of physical function at either extreme. They will help improve instrument performance in populations with broad functional ranges and those concentrated at one or the other extreme ends of

Both models have a linear form and can be solved by using a branch-and-bound algorithm. The first model assumes an item bank calibrated under the Rasch model and can be used, for instance, when classical test theory has to serve as an interface between the item bank system and a user not familiar with modern test theory. Maximization of alpha was obtained by inserting a special constra...

    2017-12-01

    Nuclear Detection Figure of Merit (NDFOM) is a DNDO-funded project at LANL to develop a software framework that allows a user to evaluate a radiation detection scenario of interest, quickly obtaining results on detector performance. It is intended as a “first step” in detector performance assessment, and meant to be easily employed by subject matter experts (SMEs) and non-SMEs alike. The generic scenario consists of a potential source moving past a detector at a relative velocity and with a distance of closest approach. Such a scenario is capable of describing, e.g., vehicles driving through portal monitors, border patrol scanning suspected illicit materials with a handheld instrument, and first responders with backpackor pager-based detectors (see Fig. 1). The backend library is prepopulated by the NDFOM developers to include sources and detectors of interest to DNDO and its community.

    Energy Technology Data Exchange (ETDEWEB)

    Cypher, B.L.; Spencer, K.A.; Scrivner, J.H.

    1995-10-01

    Food item use by coyotes was compared between sexes and among age classes at the Naval Petroleum Reserves, California. Item use did not differ significantly between males and females. Although leporid was the item most frequently used by all age classes, item use differed significantly between pups (< 1 year), yearlings (1 year), and adults (> 1 year), probably due to differential use of secondary items. Variation in item use among age classes could potentially bias results of coyote food habit studies.

  9. The Development of a Checklist to Enhance Methodological Quality in Intervention Programs

    Science.gov (United States)

    Chacón-Moscoso, Salvador; Sanduvete-Chaves, Susana; Sánchez-Martín, Milagrosa

    2016-01-01

    The methodological quality of primary studies is an important issue when performing meta-analyses or systematic reviews. Nevertheless, there are no clear criteria for how methodological quality should be analyzed. Controversies emerge when considering the various theoretical and empirical definitions, especially in relation to three interrelated problems: the lack of representativeness, utility, and feasibility. In this article, we (a) systematize and summarize the available literature about methodological quality in primary studies; (b) propose a specific, parsimonious, 12-items checklist to empirically define the methodological quality of primary studies based on a content validity study; and (c) present an inter-coder reliability study for the resulting 12-items. This paper provides a precise and rigorous description of the development of this checklist, highlighting the clearly specified criteria for the inclusion of items and a substantial inter-coder agreement in the different items. Rather than simply proposing another checklist, however, it then argues that the list constitutes an assessment tool with respect to the representativeness, utility, and feasibility of the most frequent methodological quality items in the literature, one that provides practitioners and researchers with clear criteria for choosing items that may be adequate to their needs. We propose individual methodological features as indicators of quality, arguing that these need to be taken into account when designing, implementing, or evaluating an intervention program. This enhances methodological quality of intervention programs and fosters the cumulative knowledge based on meta-analyses of these interventions. Future development of the checklist is discussed.

    Qualitative research explores complex phenomena encountered by clinicians, health care providers, policy makers and consumers. Although partial checklists are available, no consolidated reporting framework exists for any type of qualitative design. To develop a checklist for explicit and comprehensive reporting of qualitative studies (in depth interviews and focus groups). We performed a comprehensive search in Cochrane and Campbell Protocols, Medline, CINAHL, systematic reviews of qualitative studies, author or reviewer guidelines of major medical journals and reference lists of relevant publications for existing checklists used to assess qualitative studies. Seventy-six items from 22 checklists were compiled into a comprehensive list. All items were grouped into three domains: (i) research team and reflexivity, (ii) study design and (iii) data analysis and reporting. Duplicate items and those that were ambiguous, too broadly defined and impractical to assess were removed. Items most frequently included in the checklists related to sampling method, setting for data collection, method of data collection, respondent validation of findings, method of recording data, description of the derivation of themes and inclusion of supporting quotations. We grouped all items into three domains: (i) research team and reflexivity, (ii) study design and (iii) data analysis and reporting. The criteria included in COREQ, a 32-item checklist, can help researchers to report important aspects of the research team, study methods, context of the study, findings, analysis and interpretations.

  11. On Meanings and Descriptions

    Directory of Open Access Journals (Sweden)

    Mieke Bal

    1981-09-01

    Full Text Available Although descriptive passages would appear to be of marginal importance in narrative texts, they are, in fact, of both logical and semantic necessity. Narratology, therefore, must take these segments into account. In this article, I shall survey the present situation in this field and compare rival points of view. I shall also offer several suggestions for analyzing descriptions. The following topics will be discussed: the nature of description as a specific type of discourse which makes it recognizable as such; the internal structure of description; the place and function of descriptions in the text as a whole. In the latter section, the semantic impact of descriptions in the overall meaning of narrative texts will be accounted for. This article is intended as a contribution to the theory of description as a part of narratology. It also has a didactic purpose, since it proposes a model for the analysis of texts which can be used for systematic text-study, both in a historical and a comparative perspective.

  12. Open Coding Descriptions

    Directory of Open Access Journals (Sweden)

    Barney G. Glaser, PhD, Hon PhD

    2016-12-01

    Full Text Available Open coding is a big source of descriptions that must be managed and controlled when doing GT research. The goal of generating a GT is to generate an emergent set of concepts and their properties that fit and work with relevancy to be integrated into a theory. To achieve this goal, the researcher begins his research with open coding, that is coding all his data in every possible way. The consequence of this open coding is a multitude of descriptions for possible concepts that often do not fit in the emerging theory. Thus in this case the researcher ends up with many irrelevant descriptions for concepts that do not apply. To dwell on descriptions for inapplicable concepts ruins the GT theory as it starts. It is hard to stop. Confusion easily sets in. Switching the study to a QDA is a simple rescue. Rigorous focusing on emerging concepts is vital before being lost in open coding descriptions. It is important, no matter how interesting the description may become. Once a core is possible, selective coding can start which will help control against being lost in multiple descriptions.

    Fencl, Jennifer L

    2016-07-01

    A surgical item unintentionally retained in a patient after an operative or other invasive procedure is a serious, preventable medical error with the potential to cause the patient great harm. Perioperative RNs play a key role in preventing retained surgical items (RSIs). The updated AORN "Guideline for prevention of retained surgical items" provides guidance for implementing a consistent, multidisciplinary approach to RSI prevention; accounting for surgical items; preventing retention of device fragments; reconciling count discrepancies; and using adjunct technologies to supplement manual count procedures. This article focuses on key points of the guideline to help perioperative personnel provide optimal care during a procedure. Key points addressed include taking responsibility for RSI prevention as a team; minimizing distractions, noise, and interruptions during counts; using consistent counting methods; reconciling discrepancies; and participating in performance-improvement activities. Perioperative RNs should review the complete guideline for additional information and for guidance in writing and updating policies and procedures. Copyright © 2016 AORN, Inc.

    Full Text Available Wille (1996 proposed an item selection strategy which may be used to maximise, first, the internal consistency and, next, the convergent and discriminant validity of items in multi-dimensional Likert-type questionnaires or scales. In terms of his strategy, the latter aspects of validity are maximised by means of exploratory factor analyses. In this article, it is done by means of Tateneni, Mels, Cudeck and Browne’s (2001 Comprehensive Exploratory Factor Analysis (CEFA program which implements exploratory factor analysis, but provides the advantages of standard confirmatory factor analysis (e.g., the computation of the standard errors of the rotated factor loadings and measures of “model" fit.

  12. A MATHEMATICAL MODEL OF THE MILITARY TRANSPORT AIRCRAFT MOVEMENT AT CARGO ITEM DROP

    Directory of Open Access Journals (Sweden)

    2016-01-01

    Full Text Available The controllability of military transport aircraft deteriorates at heavy single piece landing. To solve this problem and a specific methodology for pilotage of the pre-emption, and automation tools are being developed. Preliminary study ofpilotage technique and authomatic control algorythm demand a reliable mathematical model of aircraft dynamics at cargo item drop. Such model should take into account significant change in the position of the aircraft center of mass and aircraft inertia tensor. Simplified models were based on modeling the movement of the center of mass and rotation around the cen- ter of mass of the aircraft. Such models do not take into account the inertial forces and moments of moving a cargo item. This circumstance does not allow to obtain reliable results in the simulation. The article presents the description of the complete mathematical model of the movement of military transport aircraft in landing of a cargo item. Examines the com- plex material system of solids and a detailed description of the properties of its components. The equations of motion of the aircraft as a system carrier (aircraft without a cargo item and wear (of moving a cargo item bodies to reflect the changes in the inertia tensor. The functioning of the power plant, steering actuators, flight control system, an exhaust chute, the sen- sors of the primary information are taken into account. The equations of motion for systems of bodies projected on the air- craft reference plane are being recorded. This approach takes into account changes of the inertia tensor and the position of the main central axes of inertia in the process of landing of a cargo item. It allows us to simulate the condition of the air- craft at all speeds of the pitch, normal overload, and masses of single piece and placement, as evidenced by the high con- vergence of modeling results with data from flight tests.

    Patient care involves several medical and surgical items, including those that come into contact with sterile or other high-risk body sites and items that have been used on other patients. These situations create a risk for infection if items are contaminated, and the implications can range from single infections to large outbreaks. To minimize the risk, proper equipment cleaning, disinfection/sterilization, storage, and monitoring practices are required. Risks posed by different items; the required level of cleaning, disinfection, or sterilization; the methods that are available and appropriate; and how to ensure efficacy, must be considered when designing and implementing an infection control program.

    Seizure semiology is important for classifying patients' epilepsy. Physicians usually get most of the seizure information from observers though there have been few reports on the reliability of the observers' description. This study aims at determining the reliability of observers' description of the semiology. We included 92 patients who had their habitual seizures recorded during video-EEG monitoring. We compared the semiology described by the observers with that recorded on the videotape, and reviewed which characteristics of the observers affected the reliability of their reported data. The classification of seizures and the individual components of the semiology based only on the observer-description was somewhat discordant compared with the findings from the videotape (correct classification, 85%). The descriptions of some ictal behaviors such as oroalimentary automatism, tonic/dystonic limb posturing, and head versions were relatively accurate, but those of motionless staring and hand automatism were less accurate. The specified directions by the observers were relatively correct. The accuracy of the description was related to the educational level of the observers. Much of the information described by well-educated observers is reliable. However, every physician should keep in mind the limitations of this information and use this information cautiously.

  5. Dissociating the neural correlates of intra-item and inter-item working-memory binding.

    Directory of Open Access Journals (Sweden)

    Carinne Piekema

    Full Text Available BACKGROUND: Integration of information streams into a unitary representation is an important task of our cognitive system. Within working memory, the medial temporal lobe (MTL has been conceptually linked to the maintenance of bound representations. In a previous fMRI study, we have shown that the MTL is indeed more active during working-memory maintenance of spatial associations as compared to non-spatial associations or single items. There are two explanations for this result, the mere presence of the spatial component activates the MTL, or the MTL is recruited to bind associations between neurally non-overlapping representations. METHODOLOGY/PRINCIPAL FINDINGS: The current fMRI study investigates this issue further by directly comparing intrinsic intra-item binding (object/colour, extrinsic intra-item binding (object/location, and inter-item binding (object/object. The three binding conditions resulted in differential activation of brain regions. Specifically, we show that the MTL is important for establishing extrinsic intra-item associations and inter-item associations, in line with the notion that binding of information processed in different brain regions depends on the MTL. CONCLUSIONS/SIGNIFICANCE: Our findings indicate that different forms of working-memory binding rely on specific neural structures. In addition, these results extend previous reports indicating that the MTL is implicated in working-memory maintenance, challenging the classic distinction between short-term and long-term memory systems.

  6. Career Path Descriptions

    Charkiewicz, A

    2000-01-01

    Before the Career Path system, jobs were classified according to grades with general statutory definitions, guided by the "Job Catalogue" which defined 6 evaluation criteria with example illustrations in the form of "typical" job descriptions. Career Paths were given concise statutory definitions necessitating a method of description and evaluation adapted to their new wider-band salary concept. Evaluations were derived from the same 6 criteria but the typical descriptions became unusable. In 1999, a sub-group of the Standing Concertation Committee proposed a new guide for describing Career Paths, adapted to their wider career concept by expanding the 6 evaluation criteria into 9. For each criterion several levels were established tracing the expected evolution of job level profiles and personal competencies over their longer salary ranges. While providing more transparency to supervisors and staff, the Guide's official use would be by services responsible for vacancy notices, Career Path evaluations and rela...

    2018-01-01

    There are widespread fatalistic beliefs in Arab countries, especially among individuals with diabetes. However, there is no tool to assess diabetes fatalism in this population. This study describes the processes used to create an Arabic version of the Diabetes Fatalism Scale (DFS) and examine its psychometric properties. A descriptive correlational design was used with a convenience sample of Lebanese adults (N = 274) with type 2 diabetes recruited from a major hospital in Beirut, Lebanon and by snowball sampling. The 12- item Diabetes Fatalism Scale- Arabic (12-item DFS-Ar) was back-translated from the original version, pilot tested on 22 adults with type 2 diabetes and then administered to 274 patients to assess the validity and reliability of the scale. Confirmatory factor analysis (CFA) was used to test the hypothesized factor structure. Cronbach's alpha was used to test for reliability. CFA supported the existence of the three factor hypothesis of the original DFS scale. The five items measuring "emotional distress" loaded under Factor 1, the four items measuring "spiritual coping" loaded under factor 2 and the last three items measuring "perceived self-efficacy" of the original scale loaded under Factor 3 (p fatalism. Further testing with larger and non-Lebanese Arabic population is needed.

    Barney G. Glaser, Ph.D.; Hon Ph.D.

    2006-11-01

    Full Text Available The literature is not kind to the use of descriptive generalizations. Authors struggle and struggle to find and rationalize a way to use them and then fail in spite of trying a myriad of work-arounds. And then we have Lincoln and Guba’s famous statement: “The only generalization is: there is no generalization” in referring to qualitative research. (op cit, p. 110 They are referring to routine QDA yielding extensive descriptions, but which tacitly include conceptual generalizations without any real thought of knowledge about them. In this chapter I wish to explore this struggle for the purpose of explaining that the various contra arguments to using descriptive generalizations DO NOT apply to the ease of using conceptual generalizations yielded in SGT and especially FGT. I will not argue for the use of descriptive generalization. I agree with Lincoln and Guba with respect to QDA, “the only generalization is: there is no generalization.” It is up to the QDA methodologists, of whom there are many; to continue the struggle and I wish them well.

    2015-03-01

    Retained surgical items (RSIs) in patients is a major operating room (OR) patient safety concern. An RSI is any surgical tool, sponge, needle or other item inadvertently left in a patients body during the course of surgery. If left undetected, RSIs may lead to serious negative health consequences such as sepsis, internal bleeding, and even death. To help physicians efficiently and effectively detect RSIs, we are developing computer-aided detection (CADe) software for X-ray (XR) image analysis, utilizing large amounts of currently available image data to produce a clinically effective RSI detection system. Physician analysis of XRs for the purpose of RSI detection is a relatively lengthy process that may take up to 45 minutes to complete. It is also error prone due to the relatively low acuity of the human eye for RSIs in XR images. The system we are developing is based on computer vision and machine learning algorithms. We address the problem of low incidence by proposing synthesis algorithms. The CADe software we are developing may be integrated into a picture archiving and communication system (PACS), be implemented as a stand-alone software application, or be integrated into portable XR machine software through application programming interfaces. Preliminary experimental results on actual XR images demonstrate the effectiveness of the proposed approach.

    Full Text Available Construction logistics are activities that consist of ordering, storage and transportation of materials of construction projects. Storage material is logistics activity that ensure the availability of materials in project site. Generally, material storage activities have been conducted at the project site. Logistics construction is aimed to support the project activities that the completion schedule has been set. Construction logistics issues is determining the schedule of ordering materials so that the project can be implemented on schedule. The purpose of research is to determine the optimum ordering period for the primary items on the main building structure construction and designing inventory control cards as a mechanism for monitoring procurement of materials. This research has been obtained optimal ordering period for the primary items of main building structure with elements of the work using Fixed Period Requirement method. Inventories were already meet the material requirement of each period. Material management has been conducted based grouping approach as many as 31 groups. In addition, this research has proposed the inventory control cards as an instrument for material procurement monitoring. The implications of inventory control cards are coordinate contracting parties with vendors to plan the replenishment  of materials to meet the work schedule. Further research can be developed with other aspects such as integrated material order system between contractors and vendors to consider the safety stock. In addition, the information system for planning material is an important consideration for construction projects with large scale so that the companies can plan primary items inventory and other materials in the projects completion more easily, quickly and accurately.

  19. XML Translator for Interface Descriptions

    Science.gov (United States)

    Boroson, Elizabeth R.

    2009-01-01

    A computer program defines an XML schema for specifying the interface to a generic FPGA from the perspective of software that will interact with the device. This XML interface description is then translated into header files for C, Verilog, and VHDL. User interface definition input is checked via both the provided XML schema and the translator module to ensure consistency and accuracy. Currently, programming used on both sides of an interface is inconsistent. This makes it hard to find and fix errors. By using a common schema, both sides are forced to use the same structure by using the same framework and toolset. This makes for easy identification of problems, which leads to the ability to formulate a solution. The toolset contains constants that allow a programmer to use each register, and to access each field in the register. Once programming is complete, the translator is run as part of the make process, which ensures that whenever an interface is changed, all of the code that uses the header files describing it is recompiled.

  20. Addressing the Language Description Deficit

    M. Ali Bolgiin

    2010-01-01

    Full Text Available Well-described language features are key to successful teaching and learning, especially for achieving advanced levels of proficiency. Other measures, such as simply increasing the number of reading and listening passages in a language program alone are not enough to bring the student to a higher level in a given skill. In fact, even being present in the target culture does not suffice. Angelelli and Degueldre (2002 argue that at advanced levels, even spending time in a country where the language is spoken is not necessarily sufficient for learners: "They do not need just exposure; they need answers to questions and explanations that they can rarely get by simply being immersed in a language/ culture." Less commonly taught languages (LCTLs lack descriptions that have such answers and explanations (cf. Fotos, 2002. It is argued in this paper that corpuslinguistic analyses help to provide actual usage-based, rather than intuition-based, descriptions and explanations of language features. Such approach is illustrated through English and Turkish examples.

    Wilkerson, J Michael; Noor, Syed W; Galos, Dylan L; Rosser, B R Simon

    2016-07-01

    In this study, we investigated if a single-item indicator measured the degree to which people were open about their same-sex attraction ("out") as accurately as a multi-item scale. For the multi-item scale, we used the Outness Inventory, which includes three subscales: family, world, and religion. We examined correlations between the single- and multi-item measures; between the single-item indicator and the subscales of the multi-item scale; and between the measures and internalized homonegativity, social attitudes towards homosexuality, and depressive symptoms. In addition, we calculated Tjur's R (2) as a measure of predictive power of the single-item indicator, multi-item scale, and subscales of the multi-item scale in predicting two health-related outcomes: depressive symptoms and condomless anal sex with multiple partners. There was a strong correlation between the single- and multi-item measures (r = 0.73). Furthermore, there were strong correlations between the single-item indicator and each subscale of the multi-item scale: family (r = 0.70), world (r = 0.77), and religion (r = 0.50). In addition, the correlations between the single-item indicator and internalized homonegativity (r = -0.63), social attitudes towards homosexuality (r = -0.38), and depression (r = -0.14) were higher than those between the multi-item scale and internalized homonegativity (r = -0.55), social attitudes towards homosexuality (r = -0.21), and depression (r = -0.13). Contrary to the premise that multi-item measures are superior to single-item measures, our collective findings indicate that the single-item indicator of outness performs better than the multi-item scale of outness.

    Given recent state legislation legalizing marijuana for recreational purposes and majority popular opinion favoring these laws, we developed the Protective Behavioral Strategies for Marijuana scale (PBSM) to identify strategies that may mitigate the harms related to marijuana use among those young people who choose to use the drug. In the current study, we expand on the initial exploratory study of the PBSM to further validate the measure with a large and geographically diverse sample (N = 2,117; 60% women, 30% non-White) of college students from 11 different universities across the United States. We sought to develop a psychometrically sound item bank for the PBSM and to create a short assessment form that minimizes respondent burden and time. Quantitative item analyses, including exploratory and confirmatory factor analyses with item response theory (IRT) and evaluation of differential item functioning (DIF), revealed an item bank of 36 items that was examined for unidimensionality and good content coverage, as well as a short form of 17 items that is free of bias in terms of gender (men vs. women), race (White vs. non-White), ethnicity (Hispanic vs. non-Hispanic), and recreational marijuana use legal status (state recreational marijuana was legal for 25.5% of participants). We also provide a scoring table for easy transformation from sum scores to IRT scale scores. The PBSM item bank and short form associated strongly and negatively with past month marijuana use and consequences. The measure may be useful to researchers and clinicians conducting intervention and prevention programs with young adults. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

  7. Polemic and Descriptive Negations

    DEFF Research Database (Denmark)

    Horslund, Camilla Søballe

    2011-01-01

    to semantics and pragmatics, negations can be used in three different ways, which gives rise to a typology of three different types of negations: 1) the descriptive negation, 2) the polemic negation, and 3) the meta-linguistic negation (Nølke 1999, 4). This typology illuminates the fact that the negation...... as such may be more or less central to the meaning of the utterance. The present paper investigates the role of morphosyntactic and prosodic prominence as well as register and social setting on the interpretation of negations. It seems plausible to expect that if the negation as such is central to the meaning...... of the utterance (as in polemic negations), the negation will be articulated prominently in order to emphasise this importance. Likewise, if the negation is not central to the meaning of the utterance, it should not be articulated prominently. Moreover, it is plausible to expect descriptive negations to be more...

    2006-01-01

    Quantification of categorical, or non-numerical, data is a problem that scientists face across a wide range of disciplines. Exploring data analysis in various areas of research, such as the social sciences and biology, Multidimensional Nonlinear Descriptive Analysis presents methods for analyzing categorical data that are not necessarily sampled randomly from a normal population and often involve nonlinear relations. This reference not only provides an overview of multidimensional nonlinear descriptive analysis (MUNDA) of discrete data, it also offers new results in a variety of fields. The first part of the book covers conceptual and technical preliminaries needed to understand the data analysis in subsequent chapters. The next two parts contain applications of MUNDA to diverse data types, with each chapter devoted to one type of categorical data, a brief historical comment, and basic skills peculiar to the data types. The final part examines several problems and then concludes with suggestions for futu...

    To determine the items (question topics) for a subjective instrument to assess degenerative joint disease (DJD)-associated chronic pain in cats and determine the instrument design most appropriate for use by cat owners. 100 randomly selected client-owned cats from 6 months to 20 years old. Cats were evaluated to determine degree of radiographic DJD and signs of pain throughout the skeletal system. Two groups were identified: high DJD pain and low DJD pain. Owner-answered questions about activity and signs of pain were compared between the 2 groups to define items relating to chronic DJD pain. Interviews with 45 cat owners were performed to generate items. Fifty-three cat owners who had not been involved in any other part of the study, 19 veterinarians, and 2 statisticians assessed 6 preliminary instrument designs. 22 cats were selected for each group; 19 important items were identified, resulting in 12 potential items for the instrument; and 3 additional items were identified from owner interviews. Owners and veterinarians selected a 5-point descriptive instrument design over 11-point or visual analogue scale formats. Behaviors relating to activity were substantially different between healthy cats and cats with signs of DJD-associated pain. Fifteen items were identified as being potentially useful, and the preferred instrument design was identified. This information could be used to construct an owner-based questionnaire to assess feline DJD-associated pain. Once validated, such a questionnaire would assist in evaluating potential analgesic treatments for these patients.

    1970-01-01

    It is pointed out that in large-scale computer software systems, program documents are too often fraught with errors, out of date, poorly written, and sometimes nonexistent in whole or in part. The means are described by which many of these typical system documentation problems were overcome in a large and dynamic software project. A systems approach was employed which encompassed such items as: (1) configuration management; (2) standards and conventions; (3) collection of program information into central data banks; (4) interaction among executive, compiler, central data banks, and configuration management; and (5) automatic documentation. A complete description of the overall system is given.

    Smoking behavior is influenced by social motivations such as the expected social benefits of smoking and the social cues that induce craving. This paper describes development of the PROMIS Social Motivations for Smoking item banks, which will serve to standardize assessment of these social motivations among daily and nondaily smokers. Daily (N = 4,201) and nondaily (N =1,183) smokers completed an online survey. Item factor analyses, item response theory analyses, and differential item functioning analyses were conducted to identify a unidimensional set of items for each group. Short forms (SFs) and computer adaptive tests (CATs) were evaluated as tools for more efficiently assessing this construct. A total of 15 items were included in the item banks (9 items common to daily and nondaily smokers, 3 unique to daily, 3 unique to nondaily). Scores based on full item banks are highly reliable (reliability = 0.90-0.91). Additionally, the item banks are strongly unidimensional and perform similarly across gender, age, and race/ethnicity groups. A fixed SF for use with both daily and nondaily smokers consists of 4 items (reliability = 0.80). Results from simulated CATs showed that, on average, fewer than 5 items are needed to assess this construct with adequate precision using the item banks. A new set of items has been identified for assessing the social motivations for smoking in a reliable, standardized manner for daily and nondaily smokers. In addition to using the full item banks, efficient assessment can be achieved by using SFs, employing CATs, or selecting items tailored to specific research or clinical purposes. © The Author 2014.

    1997-01-01

    While the methodology used in developing test items can vary significantly, to ensure quality examinations, test items should be developed systematically. Test design and development is discussed in the DOE Guide to Good Practices for Design, Development, and Implementation of Examinations. This guide is intended to be a supplement by providing more detailed guidance on the development of specific test items. This guide addresses the development of written examination test items primarily. However, many of the concepts also apply to oral examinations, both in the classroom and on the job. This guide is intended to be used as guidance for the classroom and laboratory instructor or curriculum developer responsible for the construction of individual test items. This document focuses on written test items, but includes information relative to open-reference (open book) examination test items, as well. These test items have been categorized as short-answer, multiple-choice, or essay. Each test item format is described, examples are provided, and a procedure for development is included. The appendices provide examples for writing test items, a test item development form, and examples of various test item formats.

  13. Discourse Factors Influencing Spatial Descriptions in English and German

    Science.gov (United States)

    Vorwerg, Constanze; Tenbrink, Thora

    The ways in which objects are referred to by using spatial language depend on many factors, including the spatial configuration and the discourse context. We present the results of a web experiment in which speakers were asked to either describe where a specified item was located in a picture containing several items, or which item was specified. Furthermore, conditions differed as to whether the first six configurations were specifically simple or specifically complex. Results show that speakers' spatial descriptions are more detailed if the question is where rather than which, mirroring the fact that contrasting the target item from the others in which tasks may not always require an equally detailed spatial description as in where tasks. Furthermore, speakers are influenced by the complexity of initial configurations in intricate ways: on the one hand, individual speakers tend to self-align with respect to their earlier linguistic strategies; however, also a contrast effect could be identified with respect to the usage of combined projective terms.

    2018-01-01

    This research intended to validate two brief scales of sensations seeking with Peruvian adolescents: the eight item scale (BSSS8; Hoyle, Stephenson, Palmgreen, Lorch, y Donohew, 2002) and the four item scale (BSSS4; Stephenson, Hoyle, Slater, y Palmgreen, 2003). Questionnaires were administered to 618 voluntary participants, with an average age of 13.6 years, from different levels of high school, state and private school in a district in the south of Lima. It analyzed the internal structure of both short versions using three models: a) unidimensional (M1), b) oblique or related dimensions (M2), and c) the bifactor model (M3). Results show that both instruments have a single dimension which best represents the variability of the items; a fact that can be explained both by the complexity of the concept and by the small number of items representing each factor, which is more noticeable in the BSSS4. Reliability is within levels found by previous studies: alpha: .745 = BSSS8 and BSSS4 =. 643; omega coefficient: .747 in BSSS8 and .651 in BSSS4. These are considered suitable for the type of instruments studied. Based on the correlation between the two instruments, it was found that there are satisfactory levels of equivalence between the BSSS8 and BSSS4. However, it is recommended that the BSSS4 is mainly used for research and for the purpose of describing populations.
