Full Text Available The increased use of technology within the educational field gives rise to the need for developing valid instruments to measure key constructs associated with performance. We present some self-report instruments developed and/or validated in the Italian context that could be used to assess achievement emotions and correlates, within the theoretical framework of Pekrun’s control-value model. First, we propose some data related to the construction of two instruments developed to assess ten achievement emotions: the Brief Achievement Emotions Questionnaire, BR-AEQ, used with college students, and the Graduated Achievement Emotions Set, GR-AES, used with primary school students. Second, we describe some data concerning the validation within the Italian context of two instruments assessing achievement goals as antecedents of achievement emotions: the Achievement Goal Questionnaire-Revised, AGQ-R, and its more recent version based on the 3 X 2 achievement goal model.

There is growing interest in the use of the Internet for interacting with patients, both in terms of healthcare information provision and information gathering. In this article, we examine the issues in designing healthcare websites for elderly users. In particular, this article uses a year-long case study of the development of a web-based system for self-reporting of symptoms and quality of life with a view to examine the issues relating to website design for elderly users. The issues identified included the technical, social and medical aspects of website design for elderly users. The web-based system developed was based on the European Quality of Life 5-Dimensions health-status questionnaire, a commonly used tool for patient self-reporting of quality of life, and the more specific coronary revascularisation outcome questionnaire. Currently, self-reporting is generally administered in the form of paper-based questionnaires to be completed in the outpatient clinic or at home. There are a variety of issues relating to elderly users, which imply that websites for elderly patients may involve different design considerations to other types of websites.

The medical community has recognized the importance of leadership skills among its members. While numerous leadership assessment tools exist at present, few are specifically tailored to the unique health care environment. The study team designed a 24-item survey (Healthcare Evaluation & Assessment of Leadership [HEAL]) to measure leadership competency based on the core competencies and core principles of the Duke Healthcare Leadership Model. A novel digital platform was created for use on handheld devices to facilitate its distribution and completion. This pilot phase involved 126 health care professionals self-assessing their leadership abilities. The study aimed to determine both the content validity of the survey and the feasibility of its implementation and use. The digital platform for survey implementation was easy to complete, and there were no technical problems with survey use or data collection. With regard to reliability, initial survey results revealed that each core leadership tenet met or exceeded the reliability cutoff of 0.7. In self-assessment of leadership, women scored themselves higher than men in questions related to patient centeredness ( P =0.016). When stratified by age, younger providers rated themselves lower with regard to emotional intelligence and integrity. There were no differences in self-assessment when stratified by medical specialty. While only a pilot study, initial data suggest that HEAL is a reliable and easy-to-administer survey for health care leadership assessment. Differences in responses by sex and age with respect to patient centeredness, integrity, and emotional intelligence raise questions about how providers view themselves amid complex medical teams. As the survey is refined and further administered, HEAL will be used not only as a self-assessment tool but also in "360" evaluation formats.

Background:Few studies have examined students' attitudinal perceptions of technology. There is no appropriate instrument to measure senior high school students' motivation and self-regulation toward technology learning among the current existing instruments in the field of technology education. Purpose:The present study is to validate an instrument for assessing senior high school students' motivation and self-regulation towards technology learning. Sample:A total of 1822 Taiwanese senior high school students (1020 males and 802 females) responded to the newly developed instrument. Design and method:The Motivation and Self-regulation towards Technology Learning (MSRTL) instrument was developed based on the previous instruments measuring students' motivation and self-regulation towards science learning. Exploratory and confirmatory factor analyses were utilized to investigate the structure of the items. Cronbach's alpha was applied for measuring the internal consistency of each scale. Furthermore, multivariate analysis of variance was used to examine gender differences. Results:Seven scales, including 'Technology learning self-efficacy,' 'Technology learning value,' 'Technology active learning strategies,' 'Technology learning environment stimulation,' 'Technology learning goal-orientation,' 'Technology learning self-regulation-triggering,' and 'Technology learning self-regulation-implementing' were confirmed for the MSRTL instrument. Moreover, the results also showed that male and female students did not present the same degree of preference in all of the scales. Conclusions:The MSRTL instrument composed of seven scales corresponding to 39 items was shown to be valid based on validity and reliability analyses. While male students tended to express more positive and active performance in the motivation scales, no gender differences were found in the self-regulation scales.

Public speaking is the most commonly reported fearful social situation. Although a number of contemporary theories emphasize the importance of cognitive processes in social anxiety, there is no instrument available to assess fearful thoughts experienced during public speaking. The Self-Statements During Public Speaking (SSPS) scale is a 10-item questionnaire consisting of two 5-item subscales, the “Positive Self-Statements” (SSPS-P) and the “Negative Self-Statements” subscale (SSPS-N). Four studies report on the development and the preliminary psychometric properties of this instrument. PMID:16763666

. In this paper, we present a set of instrument`s designed to identify at-risk undergraduate students in a Problem-based Learning (PBL) university, using an introductory programming course between two campus locations as a case study. Collectively, these instruments form the basis of a proposed learning ecosystem...... in the prediction model. Results of a multiple linear regression model found several significant assessment predictors related to how often students attempted self-guided course assignments and their self-reported programming experience, among others.......Technical educations often experience poor student performance and consequently high rates of attrition. Providing students with early feedback on their learning progress can assist students in self-study activities or in their decision-making process regarding a change in educational direction...

To identify the psychometric properties of evaluation instruments that measure mediators of dietary behaviors in school-aged children. Systematic search of scientific databases limited to 1999-2010. Psychometric properties related to development and testing of self-report instruments for children 8-12 years old. Systematic search of 189 articles and review of 15 instruments (20 associated articles) meeting the inclusion criteria. Search terms used included children, school, nutrition, diet, nutrition education, and evaluation. Fourteen studies used a theoretical framework to guide the instrument's development. Knowledge and self-efficacy were the most commonly used psychosocial measures. Twelve instruments focused on specific nutrition-related behaviors. Eight instruments included over 40 items and used age-appropriate response formats. Acceptable reliability properties were most commonly reported for attitude and self-efficacy measures. Although most of the instruments were reviewed by experts (n = 8) and/or pilot-tested (n = 9), only 7 were tested using both rigorous types of validity and with low-income youth. Results from this review suggest that additional research is needed to develop more robust psychosocial measures for dietary behaviors, for low-income youth audiences.

Self-reported health measures are important indicators used by clinicians and researchers for the evaluation of health interventions, outcome assessment of clinical studies, and identification of health needs to improve resource allocation. However, the application of self-reported health measures relies on developing reliable and valid instruments that are suitable across diverse populations. The main objective of this study is to evaluate the construct validity of the SF-12v.2, an instrument for measuring self-rated physical and mental health, for homeless adults with mental illness. Various interventions have been aimed at improving the health of homeless people with mental illness, and the development of valid instruments to evaluate these interventions is imperative. We measured self-rated mental and physical health from a quota sample of 575 homeless people with mental illness using the SF-12v2, EQ-5D, Colorado Symptoms Index, and physical/mental health visual analogue scales. We examined the construct validity of the SF-12v2 through confirmatory factor analyses (CFA), and using ANOVA/correlation analyses to compare the SF-12v2 to the other instruments to ascertain discriminant/convergent validity. Our CFA showed that the measurement properties of the original SF-12v2 model had a mediocre fit with our empirical data (χ2 = 193.6, df = 43, p physical and mental health status for a homeless population with mental illness.

The development of an instrument to measure the concentration of particles in gas is described in this report. An in situ instrument was designed and constructed which sizes individual particles and counts the number of occurrences for several size classes. Although this instrument was designed to detect the size distribution of slag and seed particles generated at an experimental coal-fired magnetohydrodynamic power facility, it can be used as a nonintrusive diagnostic tool for other hostile industrial processes involving the formation and growth of particulates. Two of the techniques developed are extensions of the widely used crossed beam velocimeter, providing simultaneous measurement of the size distribution and velocity of articles.

Modern healthcare institutions are continuously changing, and Self-Directed Learning (SDL) abilities are considered a prerequisite for both nursing students and nurses in order to be proactive about these demanding challenges. To date, no systematic reviews of existing instruments aimed at detecting and critically evaluating SDL abilities have been published. Therefore, the aims of this review are: 1) identify the instruments for assessment of SDL abilities among nursing students and nurses; 2) critically evaluate the methodological studies quality; and 3) compare the psychometric properties of the available instruments. A psychometric-systematic-review was performed. CDSR, CINAHL, ERIC, MEDLINE, PROSPERO, SCOPUS databases were searched without restrictions in time and setting. All primary studies involving nursing students or nurses, written in English and aimed at validating SDL assessment tools, were included. Studies retrieved were evaluated according to the COnsensus-based-Standards for the selection of health Measurement-INstruments (COSMIN) panel. Study inclusion, data extraction and quality assessment were performed by researchers independently. Eleven studies were included and four tools based on Knowles's theory have emerged: 1) the Self-Directed Learning Readiness Scale; 2) the Self-Directed Learning Readiness Scale for Nursing Education; 3) the Self-Rating Scale of Self-Directed Learning, and 4) the Self-Directed Learning Instrument. A few psychometric properties have been considered in each study, from two to four out of the ten required. The quality of the methodologies used was in general, from fair to poor with the exception of one instrument (the Self-Directed-Learning-Instrument). The psychometric proprieties that emerged across the tools were good in general: the Cronbach α was from 0.73 to 0.91; structural validities have also reported good indexes both in the explorative and in the confirmative factor analyses.

Increasing breastfeeding rates in the United States is a national priority. Yet, initiation and duration of breastfeeding remains below national targets. Breastfeeding self-efficacy has been shown to be a strong predictor of both breastfeeding initiation and duration and is therefore an important characteristic to be able to measure. However, there is currently a myriad of instruments for measuring breastfeeding self-efficacy, which makes selection of an appropriate instrument difficult. Thus, our aim was to identify, compare, and critically review available breastfeeding self-efficacy instruments. In a systematic review, 6 breastfeeding self-efficacy instruments were identified. The instruments’ purposes, theoretical framework, final scale development, and application in 5 most recent settings were analyzed. The 6 breastfeeding self-efficacy instruments apply a number of theoretical and conceptual frameworks in their development, with Bandura’s social cognitive theory being most common. Content, construct, and predictive validity were strong for most scales. Some, but not all, have been successfully adapted to novel settings. In sum, there are several measurements of breastfeeding self-efficacy that can and should be employed to better understand reasons for suboptimal breastfeeding rates and the effects of interventions on breastfeeding self-efficacy. Instrument selection should be based on domains of primary interest, time available, peripartum timing, and assessment of previous adaptations. Failure to apply appropriate measures in research may garner results that are inconclusive, inaccurate, or nonrepresentative of true study effects. PMID:26319113

Embedded instrumentation and control systems that can operate in extreme environments are challenging to design and operate. Extreme environments limit the options for sensors and actuators and degrade their performance. Because sensors and actuators are necessary for feedback control, these limitations mean that designing embedded instrumentation and control systems for the challenging environments of nuclear reactors requires advanced technical solutions that are not available commercially. This report details the development of testbed that will be used for cross-cutting embedded instrumentation and control research for nuclear power applications. This research is funded by the Department of Energy's Nuclear Energy Enabling Technology program's Advanced Sensors and Instrumentation topic. The design goal of the loop-scale testbed is to build a low temperature pump that utilizes magnetic bearing that will be incorporated into a water loop to test control system performance and self-sensing techniques. Specifically, this testbed will be used to analyze control system performance in response to nonlinear and cross-coupling fluid effects between the shaft axes of motion, rotordynamics and gyroscopic effects, and impeller disturbances. This testbed will also be used to characterize the performance losses when using self-sensing position measurement techniques. Active magnetic bearings are a technology that can reduce failures and maintenance costs in nuclear power plants. They are particularly relevant to liquid salt reactors that operate at high temperatures (700 C). Pumps used in the extreme environment of liquid salt reactors provide many engineering challenges that can be overcome with magnetic bearings and their associated embedded instrumentation and control. This report will give details of the mechanical design and electromagnetic design of the loop-scale embedded instrumentation and control testbed.

Several instruments are available to assess children's health-related quality of life (HRQoL) based on self reports as well as proxy reports from parents. Previous studies have found only low-to-moderate agreement between self and proxy reports, but few studies have explicitly compared the psychometric qualities of both. This study compares the reliability, factorial validity and convergent and known group validity of the self-report and parent-report versions of the HRQoL KINDL-R questionnaire for children and adolescents. Within the nationally representative cross-sectional German Health Interview and Examination Survey for Children and Adolescents (KiGGS), 6,813 children and adolescents aged 11 to 17 years completed the KINDL-R generic HRQoL instrument while their parents answered the KINDL proxy version (both in paper-and-pencil versions). Cronbach's alpha and confirmatory factor-analysis models (linear structural equation model) were obtained. Convergent and discriminant validity were assessed by calculating the Pearson's correlation coefficient for the Strengths and Difficulties Questionnaire. Known-groups differences were examined (ANOVA) for obese children and children with a lower familial socio-economic status. The parent reports achieved slightly higher Cronbach's alpha values for the total score (0.86 vs. 0.83) and most sub-scores. Confirmatory factor analysis revealed an acceptable fit of the six-dimensional measurement model of the KINDL for the parent (RMSEA=0.07) and child reports (RMSEA=0.06). Factorial invariance across the two versions did not hold with regards to the pattern of loadings, the item errors and the covariation between latent concepts. However the magnitude of the differences was rather small. The parent report version achieved slightly higher convergent validity (r=0.44-0.63 vs. r=0.33-0.59) in the Strengths and Difficulties Questionnaire. No clear differences were observed for known-groups validity. Our study showed that parent

This report details the current progress in the design, implementation, and validation of the signal conditioning circuitry used in a measurement instrumentation system. The purpose of this text is to document the current progress of a particular design in signal conditioning circuitry in an instrumentation system. The input of the signal conditioning circuitry comes from a piezoresistive transducer and the output will be fed to a 250 ksps, 12-bit analog-to-digital converter (ADC) with an input range of 0-5 V. It is assumed that the maximum differential voltage amplitude input from the sensor is 20 mV with an unknown, but presumably high, sensor bandwidth. This text focuses on a specific design; however, the theory is presented in such a way that this text can be used as a basis for future designs.

The self-concept of adolescents with cleft lip and palate: a pilot study using a multidimensional/hierarchical measurement instrument.

2006-09-01

To pilot the use of a multidimensional/hierarchical measurement instrument called the self-description questionnaire II to determine whether specific areas of self-concept in a group of adolescents with cleft lip and palate would be affected by their condition when compared with a normative sample. The self-concept of 23 adolescents with a cleft of the lip and palate was compared to an Australian normative sample. Adolescents attending the dental department of a paediatric hospital in Australia. The main outcome measure was a self-report questionnaire (102 items) with 10 domain-specific scales and a global measure of general self-concept. When compared to the normative data the study group showed significant differences in 4 of the 11 domain-specific scales: Parent Relations (P self-concepts. These differences were in a positive direction. Global self-concept as measured by the General Self scale was not significantly different from the normative sample. These results suggest that adolescents with clefts of the lip and palate have normative if not better self-concept than their peers. The study also suggests that having a cleft of the lip and palate has specific rather than broad associations with psychosocial adjustment. This justifies the use of instruments designed to assess specific areas of self-concept rather than more global measures.

Purpose The purpose of this study is to assess the extant literature on instruments used to measure self-efficacy in youth with type 1 diabetes (T1DM) and their caregivers and to critically evaluate these measurements. Methods An integrative review (2003–2013) was conducted searching PsycINFO, Cumulative Index to Nursing and Allied Health Literature (CINAHL), and U.S. National Library of Medicine PubMed service (PubMed) databases using key words diabetes, type 1 diabetes, and self-efficacy. The authors reviewed the resulting294 references for inclusion criteria of (a) sample of youth with T1DM or sample of caregivers of youth with T1DM, (b) description of the self-efficacy instrument as primary research, and (c) the instrument measured self-efficacy specifically related to diabetes management. Forty-five articles out of the initial 294 met criteria. Results Of the 45 articles, 10 different self-efficacy instruments were identified. The primary theoretical framework used was Bandura’s social cognitive theory and model of self-efficacy. Most participants were white middle class T1DM youth. Evaluations to assess validity often were not reported; however, a majority of studies reported high internal consistency of the instruments. Conclusions Sample homogeneity could limit the applicability of results to certain patient populations. Further psychometric analysis, including validity assessments, should be conducted in more diverse samples. Development of valid and reliable instruments for measuring self-efficacy that are sensitive to change across a wider caregiver base over time is necessary. While this review examined reliable and valid instruments used in research, future opportunities include evaluation of measuring self-efficacy in T1DM youth exposed to recent advances in diabetes management technologies.

Self-reported outcome instruments in health research have become increasingly important over the last decades. Occupational therapy interventions often focus on occupational balance. However, instruments to measure occupational balance are scarce. The aim of the study was therefore to develop a generic self-reported outcome instrument to assess occupational balance based on the experiences of patients and healthy people including an examination of its psychometric properties. We conducted a qualitative analysis of the life stories of 90 people with and without chronic autoimmune diseases to identify components of occupational balance. Based on these components, the Occupational Balance-Questionnaire (OB-Quest) was developed. Construct validity and internal consistency of the OB-Quest were examined in quantitative data. We used Rasch analyses to determine overall fit of the items to the Rasch model, person separation index and potential differential item functioning. Dimensionality testing was conducted by the use of t-tests and Cronbach's alpha. The following components emerged from the qualitative analyses: challenging and relaxing activities, activities with acknowledgement by the individual and by the sociocultural context, impact of health condition on activities, involvement in stressful activities and fewer stressing activities, rest and sleep, variety of activities, adaptation of activities according to changed living conditions and activities intended to care for oneself and for others. Based on these, the seven items of the questionnaire (OB-Quest) were developed. 251 people (132 with rheumatoid arthritis, 43 with systematic lupus erythematous and 76 healthy) filled in the OB-Quest. Dimensionality testing indicated multidimensionality of the questionnaire (t = 0.58, and 1.66 after item reduction, non-significant). The item on the component rest and sleep showed differential item functioning (health condition and age). Person separation index was 0

The development of accurate and objective tools for monitoring of ingestive behavior (MIB) is one of the most important needs facing studies of obesity and eating disorders. This paper presents the design of an instrumentation module for non-invasive monitoring of food ingestion in laboratory studies. The system can capture signals from a variety of sensors that characterize ingestion process (such as acoustical and other swallowing sensors, strain sensor for chewing detection and self-report buttons). In addition to the sensors, the data collection system integrates time-synchronous video footage that can be used for annotation of subject's activity. Both data and video are simultaneously and synchronously acquired and stored by a LabVIEW-based interface specifically developed for this application. This instrumentation module improves a previously developed system by eliminating the post-processing stage of data synchronization and by reducing the risks of operator's error.

Most statistical methods that adjust analyses for dietary measurement error treat an individual's usual intake as a fixed quantity. However, usual intake, if defined as average intake over a few months, varies over time. We describe a model that accounts for such variation and for the proximity of biomarker measurements to self-reports within the framework of a meta-analysis, and apply it to the analysis of data on energy, protein, potassium, and sodium from a set of five large validation studies of dietary self-report instruments using recovery biomarkers as reference instruments. We show that this time-varying usual intake model fits the data better than the fixed usual intake assumption. Using this model, we estimated attenuation factors and correlations with true longer-term usual intake for single and multiple 24-hour dietary recalls (24HRs) and food frequency questionnaires (FFQs) and compared them with those obtained under the "fixed" method. Compared with the fixed method, the estimates using the time-varying model showed slightly larger values of the attenuation factor and correlation coefficient for FFQs and smaller values for 24HRs. In some cases, the difference between the fixed method estimate and the new estimate for multiple 24HRs was substantial. With the new method, while four 24HRs had higher estimated correlations with truth than a single FFQ for absolute intakes of protein, potassium, and sodium, for densities the correlations were approximately equal. Accounting for the time element in dietary validation is potentially important, and points toward the need for longer-term validation studies.

The objective of this paper is to present the development results of the nuclear instrumentation and control system in Taiwan. As the Taiwan nuclear power plants age, the need to consider upgrading of both their safety and non-safety-related instrumentation and control systems becomes more urgent. Meanwhile, the digital instrumentation and control system that is based on current fast evolving electronic and information technologies are difficult to maintain effectively. Therefore, Institute of Nuclear Energy Research was made a decision to promote the Taiwan Nuclear Instrumentation and Control System project to collaborate with domestic electronic industry to establish self-reliant capabilities on the design, manufacturing, and application of nuclear instrumentation and control systems with newer technology. In the case of safety-related applications like nuclear instrumentation and control, safety-oriented quality control is required. In order to establish a generic qualified digital platform, the world-wide licensing experience should be considered in the licensing process. This paper describes the qualification and certification tools by IEC 61508 for design and development of safety related equipment and explains the basis for many decisions made while performing the digital upgrade.

To examine the usability of the self-report instrument, Your Ideas about Participation and Environment (YIPE), among adults with a brain injury by exploring the value and acceptability of the instrument. A qualitative descriptive research design was used for the purpose of testing and developing the YIPE for use among adults with a brain injury. The study involved administering the YIPE followed by in-depth interviewing about the experience of taking the instrument with seven adults with a brain injury, recruited through a community-based support service organization. A descriptive thematic approach was used to analyse the content of the interview data, categorize common ideas and identify areas for improvement within the instrument. Participants were generally positive about the importance of the participation and environment topics and willing to engage in self report. The YIPE (2012), resulting from changes made to the language and structure, was found to be more useable, valued and accepted by these participants than the previous version, YIPE (2011). The YIPE was found to be a useful tool among study participants. The YIPE topics were found to have importance and relevance when considering participants' satisfaction with areas of life and aspects of environment requiring change. More development of the tool is required in terms of the wording, format and method of administration to improve the overall usability of the instrument. Implications for Rehabilitation The preliminary results from this small sample study illustrated that people with brain injury were able to use an International Classification of Functioning, Disability and Health-based tool, and confirmed the importance of considering both participation and the environment together. People with cognitive impairments associated with brain injury reported on areas of everyday life where they were satisfied or dissatisfied. They related their satisfaction to environmental factors that were facilitators

Full Text Available The ADHD Rating Scale (ADHD RS-IV; parent report and Adult ADHD Self-Rating Scale (ASRS; self-report are validated instruments for measuring symptoms of attention-deficit/hyperactivity disorder (ADHD. The objectives of this study were to elicit descriptions of phenylketonuria (PKU symptoms and assess content validity of these instruments in PKU. Parents (N = 15 of children with PKU (≥8 years old and adults with PKU (N=13 described PKU-related symptoms and commented on the scale’s clarity, comprehensiveness, and relevance to their experience with PKU. Most of the adults (84.6% and all of the children were on a phenylalanine-restricted diet, according to respondent report. The inattentiveness symptoms reported by participants mapped to the inattentive items of the questionnaires. Most participants felt the inattentive items were clear and relevant to their experience. Despite study design limitations, these results demonstrate the relevance of assessing inattentiveness in PKU, and both instruments achieved content validity for inattentive subscale items.

2018-01-01

Full Text Available This research was describing the designing of instrument for affective assessment in English language teaching. The focus of the designing was only for observation sheet that will be used by English teachers during the teaching and learning process. The instrument was designed based on scientific approach that has five stages namely observing, questioning, experimenting, associating, and communicating. In the designing process, ADDIE Model was used as the method of research. The designing of instrument was considering the gap between the reality and the teachers’ need. The result showed that the designing was also notice to the affective taxonomy such as receiving, responding, valuing, organization, and characterization. Then, three key words were used as the indicator to show the five levels of affective taxonomy such as seriously, volunteer, and without asked by teacher. Furthermore, eighteen types of affective such as religious, honesty, responsible, discipline, hard work, self confidence, logical thinking, critical thinking, creative, innovative, independent, curiosity, love knowledge, respect, polite, democracy, emotional intelligence, and pluralist were put on each stage of scientific approach. So, it is hoped that can be implemented in all of context of English language teaching at schools and can assess the students’ affective comprehensively.

2004-03-01

We performed a global self-assessment of continence following radical retropubic prostatectomy (RRP) and determined how this global self-assessment of continence correlates with commonly used definitions of continence. Between October 2000 and February 2002 all men who underwent RRP were encouraged to complete the University of California-Los Angeles Prostate Cancer Index 3, 6, 12 and 24 months postoperatively. Beginning October 2002 a single question capturing the patient global self-assessment of continence status was added to the postoperative continence assessment. The study design was cross-sectional since only continence surveys submitted between October 2002 through February 2003 were evaluated. Sensitivity, specificity and kappa coefficient was determined for the relationship between the patient global assessment of continence vs the definition of continence based on pad requirement, problem due to incontinence and frequency of incontinence. Continence progressively improved 3 to 24 months following RRP for all continence outcomes. At 24 months following RRP 97.1% of men considered themselves continent, while 97.1%, 94.1% and 97.1% were considered continent using continence definitions, including the requirement of no or 1 pad in a 24-hour interval, no or slight bother due to incontinence and total control or occasional dribbling, respectively. Our 3 definitions of continence derived from responses to the University of California-Los Angeles Prostate Cancer Index had excellent agreement with patient global self-assessment of continence (kappa coefficients between 0.76 and 0.83). The majority of men achieve continence without invasive intervention following RRP. Final continence status should be ascertained at 24 months. The patient global assessment of continence provides face validity for other definitions of continence based on responses to validated self-administered questionnaires.

This study aimed to develop self-concept instrument for undergraduate students of mathematics education in Palembang, Indonesia. Type of this study was development research of non-test instrument in questionnaire form. A Validity test of the instrument was performed with construct validity test by using Pearson product moment and factor analysis, while reliability test used Cronbach’s alpha. The instrument was tested by 65 undergraduate students of mathematics education in one of the universities at Palembang, Indonesia. The instrument consisted of 43 items with 7 aspects of self-concept, that were the individual concern, social identity, individual personality, view of the future, the influence of others who become role models, the influence of the environment inside or outside the classroom, and view of the mathematics. The result of validity test showed there was one invalid item because the value of Pearson’s r was 0.107 less than the critical value (0.244; α = 0.05). The item was included in social identity aspect. After the invalid item was removed, Construct validity test with factor analysis generated only one factor. The Kaiser-Meyer-Olkin (KMO) coefficient was 0.846 and reliability coefficient was 0.91. From that result, we concluded that the self-concept instrument for undergraduate students of mathematics education in Palembang, Indonesia was valid and reliable with 42 items.

The objective of the study is for system designers to understand the technical state of the piping and instrumentation design of RHRS (or SCS) in the commercial nuclear power plants, thus to design more uncomplicated and advanced system. In this study, we have reviewed the design requirements and the technical state of piping and instrumentation design. Firstly we have reviewed the design requirements, including functional, isolation, pressure relief, pump protection, test requirements, etc.. Especially we have separately reviewed the design requirements of the low temperature overpressure, including ASME code requirements. Also we have reviewed the technical state of piping and instrumentation design, including piping design, PAMS design, ESFAS design, relief valve design, and instrument/valve/pump control design. In the piping design, the technical state of design has been investigated classified by the five regions, which have a little different design features, from the RCS suction line to the LPSI header line. Commonly, the P and ID is the design output which the related design requirements of the system have been all applied, also the operations for in-service inspection, heat-up/normal/cool-down, and emergency have been all considered. If we can understand well the design bases and its meanings of the P and ID, it would be helpful for us to design more uncomplicated and advanced system

Home care patients often use many medications and are prone to drug-related problems (DRPs). For the management of problems related to drug use, home care could add to the multidisciplinary expertise of general practitioners (GPs) and pharmacists. The home care observation of medication-related problems by home care employees (HOME)-instrument is paper-based and assists home care workers in reporting potential DRPs. To facilitate the multiprofessional consultation, a digital report of DRPs from the HOME-instrument and digital monitoring and consulting of DRPs between home care and general practices and pharmacies is desired. The objective of this study was to develop an electronic HOME system (eHOME), a mobile version of the HOME-instrument that includes a monitoring and a consulting system for primary care. The development phase of the Medical Research Council (MRC) framework was followed in which an iterative human-centered design (HCD) approach was applied. The approach involved a Delphi round for the context of use and user requirements analysis of the digital HOME-instrument and the monitoring and consulting system followed by 2 series of pilots for testing the usability and redesign. By using an iterative design approach and by involving home care workers, GPs, and pharmacists throughout the process as informants, design partners, and testers, important aspects that were crucial for system realization and user acceptance were revealed. Through the report webpage interface, which includes the adjusted content of the HOME-instrument and added home care practice-based problems, home care workers can digitally report observed DRPs. Furthermore, it was found that the monitoring and consulting webpage interfaces enable digital consultation between home care and general practices and pharmacies. The webpages were considered convenient, clear, easy, and usable. By employing an HCD approach, the eHOME-instrument was found to be an easy-to-use system. The systematic

Body awareness: construct and self-report measures.

Full Text Available Heightened body awareness can be adaptive and maladaptive. Improving body awareness has been suggested as an approach for treating patients with conditions such as chronic pain, obesity and post-traumatic stress disorder. We assessed the psychometric quality of selected self-report measures and examined their items for underlying definitions of the construct.PubMed, PsychINFO, HaPI, Embase, Digital Dissertations Database.Abstracts were screened; potentially relevant instruments were obtained and systematically reviewed. Instruments were excluded if they exclusively measured anxiety, covered emotions without related physical sensations, used observer ratings only, or were unobtainable. We restricted our study to the proprioceptive and interoceptive channels of body awareness. The psychometric properties of each scale were rated using a structured evaluation according to the method of McDowell. Following a working definition of the multi-dimensional construct, an inter-disciplinary team systematically examined the items of existing body awareness instruments, identified the dimensions queried and used an iterative qualitative process to refine the dimensions of the construct.From 1,825 abstracts, 39 instruments were screened. 12 were included for psychometric evaluation. Only two were rated as high standard for reliability, four for validity. Four domains of body awareness with 11 sub-domains emerged. Neither a single nor a compilation of several instruments covered all dimensions. Key domains that might potentially differentiate adaptive and maladaptive aspects of body awareness were missing in the reviewed instruments.Existing self-report instruments do not address important domains of the construct of body awareness, are unable to discern between adaptive and maladaptive aspects of body awareness, or exhibit other psychometric limitations. Restricting the construct to its proprio- and interoceptive channels, we explore the current understanding

Instrument design and optimization using genetic algorithms

Hoelzel, Robert; Bentley, Phillip M.; Fouquet, Peter

2006-01-01

This article describes the design of highly complex physical instruments by using a canonical genetic algorithm (GA). The procedure can be applied to all instrument designs where performance goals can be quantified. It is particularly suited to the optimization of instrument design where local optima in the performance figure of merit are prevalent. Here, a GA is used to evolve the design of the neutron spin-echo spectrometer WASP which is presently being constructed at the Institut Laue-Langevin, Grenoble, France. A comparison is made between this artificial intelligence approach and the traditional manual design methods. We demonstrate that the search of parameter space is more efficient when applying the genetic algorithm, and the GA produces a significantly better instrument design. Furthermore, it is found that the GA increases flexibility, by facilitating the reoptimization of the design after changes in boundary conditions during the design phase. The GA also allows the exploration of 'nonstandard' magnet coil geometries. We conclude that this technique constitutes a powerful complementary tool for the design and optimization of complex scientific apparatus, without replacing the careful thought processes employed in traditional design methods

The aims of this study were to identify all available self-administered instruments measuring health literacy in people with diabetes and to determine the current instrument that is the most appropriate for applying to this population in both practice and research. A systematic review of measurement properties. MEDLINE, EMBASE and CINAHL electronic databases from their inception up to 28 March 2016. The methodological quality of each included study was assessed using the COnsensus-based Standards for the selection of health Measurement INstruments checklist. The reported results for measurement properties in the studies were assessed according to Terwee's quality criteria. Thirteen self-administered instruments measuring health literacy in people with diabetes were identified, of which six (44%) were diabetes-specific instruments. The instruments that covered the broadest contents of health literacy were the Health Literacy Scale and Health Literacy Questionnaire. The (test-retest) reliability, measurement error and responsiveness were not evaluated for any instrument, while internal consistency and hypothesis testing validity were the most frequently assessed measurement properties. With the current evidence, the Health Literacy Scale may be the most appropriate instrument for patients with diabetes in practice and research. However, the structural validity of this scale needs to be further established, particularly in other language versions. It is also recommended to use the Diabetes Numeracy Test-15 along with the Health Literacy Scale to complement the lack of numeracy measures in the Health Literacy Scale. © 2017 John Wiley & Sons Ltd.

Polarized BRDF measurement of steel E235B in the near-infrared region: Based on a self-designed instrument with absolute measuring method

Liu, Yanlei; Yu, Kun; Liu, Zilong; Zhao, Yuejin; Liu, Yufang

2018-06-01

The spectral bidirectional reflectance distribution (BRDF) offers a complete description of the optical properties of the opaque material. Numerous studies on BRDF have been conducted for its important role in scientific research and industrial production. However, most of these studies focus on the visible region and unpolarized BRDF, and the spectral polarized BRDF in the near-infrared region is rarely reported. In this letter, we propose an absolute method to measure the spectral BRDF in the near-infrared region, and the detailed derivation is presented. A self-designed instrument is set up for the absolute measurement of BRDF. The reliability of this method is verified by comparing the experimental data of the three metal (aluminum, silver and gold) mirrors with the reference data. The in-plane polarized BRDF of steel E235B are measured, and the influence of incident angle and roughness on the BRDF are discussed. The degree of linear polarization (DOLP) are determined based on the polarized BRDF. The results indicate that both the roughness and incident angle have distinct influence on the BRDF and DOLP.

IT-related self-efficacy has been found to have a critical influence on system use. However, traditional measures of computer self-efficacy and Internet-related self-efficacy are perceived to be inapplicable in the context of mobile computing and commerce because they are targeted primarily at either desktop computer or wire-based technology contexts. Based on previous research, this study develops and validates a multidimensional instrument for measuring mobile computing self-efficacy (MCSE). This empirically validated instrument will be useful to researchers in developing and testing the theories of mobile user behavior, and to practitioners in assessing the mobile computing self-efficacy of users and promoting the use of mobile commerce systems.

2014-12-03

Research on Internet-based interventions typically use digital versions of pen and paper self-report symptom scales. However, adaptation into the digital format could affect the psychometric properties of established self-report scales. Several studies have investigated differences between digital and pen and paper versions of instruments, but no systematic review of the results has yet been done. This review aims to assess the interformat reliability of self-report symptom scales used in digital or online psychotherapy research. Three databases (MEDLINE, Embase, and PsycINFO) were systematically reviewed for studies investigating the reliability between digital and pen and paper versions of psychiatric symptom scales. From a total of 1504 publications, 33 were included in the review, and interformat reliability of 40 different symptom scales was assessed. Significant differences in mean total scores between formats were found in 10 of 62 analyses. These differences were found in just a few studies, which indicates that the results were due to study effects and sample effects rather than unreliable instruments. The interformat reliability ranged from r=.35 to r=.99; however, the majority of instruments showed a strong correlation between format scores. The quality of the included studies varied, and several studies had insufficient power to detect small differences between formats. When digital versions of self-report symptom scales are compared to pen and paper versions, most scales show high interformat reliability. This supports the reliability of results obtained in psychotherapy research on the Internet and the comparability of the results to traditional psychotherapy research. There are, however, some instruments that consistently show low interformat reliability, suggesting that these conclusions cannot be generalized to all questionnaires. Most studies had at least some methodological issues with insufficient statistical power being the most common issue

This report presents the authors collective opinions on the value to the nuclear industry of the various investigations performed at TMI-2 by the Instrumentation and Electrical Program. The authors demonstrate that more attention must be given to the prevention of moisture intrusion during design, construction, operation, and maintenance of a nuclear power plant. They also point out that, while basic engineering designs of instruments are more than adequate, the applications engineering and specifications could be improved. Finally, they show that advanced testing technology, exemplified by the Electrical Circuit Characterization and Diagnostics (ECCAD) System, may be very useful as a diagnostic tool when used as part of the testing or maintenance program in a nuclear power plant

Informal caregivers of people with advanced cancer experience many negative impacts as a result of their role. There is a lack of suitable measures specifically designed to assess their experience. This study aimed to develop a new measure to assess self-efficacy in caregivers of people with advanced cancer. The development and testing of the new measure consisted of four separate, sequential phases: generation of issues, development of issues into items, pilot testing and field testing. In the generation of issues, 17 caregivers were interviewed to generate data. These data were analysed to generate codes, which were then systematically developed into items to construct the instrument. The instrument was pilot tested with 14 health professionals and five caregivers. It was then administered to a large sample for field testing to establish the psychometric properties, with established measures including the Brief Cope and the Family Appraisals for Caregiving Questionnaire for Palliative Care. Ninety-four caregivers completed the questionnaire booklet to establish the factor structure, reliability and validity. The factor analysis resulted in a 21-item, four-factor instrument, with the subscales being termed Resilience, Self-Maintenance, Emotional Connectivity and Instrumental Caregiving. The test-retest reliability and internal consistency were both excellent, ranging from 0.73 to 0.85 and 0.81 to 0.94, respectively. Six convergent and divergent hypotheses were made, and five were supported. This study has developed a new instrument to assess self-efficacy in caregivers of people with advanced cancer. The result is a four-factor, 21-item instrument with demonstrated reliability and validity. Copyright © 2012 John Wiley & Sons, Ltd.

Health physics instrumentation - a progress report

International Nuclear Information System (INIS)

Maushart, R.

1992-01-01

Health Physics Instruments have changed rather dramatically in the past decade. On the one hand, technological innovations like Microprocessors, data storage facilities and imaging displays have altered shape, size and appearance of the classical devices, particularly the hand-held ones. On the other hand, instruments are increasingly being considered as an integral part of Radiation Protection procedures and organizations, supporting a smooth and reliable implementation of all necessary measures. This implies ease of operation, and extensive self-checking and performance control features. Since there are different categories of users with quite different degrees of motivation and training, the measuring instruments of the future will have to be adapted to specific types of users. Instruments for 'professional' radiation protection - for example in nuclear power plants and nuclear technology - will differ from instruments used in the radionuclide laboratory, where radiation protection will necessarily have to be done as a 'side-job'.

Students' motivational beliefs and self-regulatory practices have been identified as instrumental in influencing the engagement of students in the learning process. An important aim of science education is to empower students by nurturing the belief that they can succeed in science learning and to cultivate the adaptive learning strategies required to help to bring about that success. This article reports the development and validation of an instrument to measure salient factors related to the motivation and self-regulation of students in lower secondary science classrooms. The development of the instrument involved identifying key determinants of students' motivation and self-regulation in science learning based on theoretical and research underpinnings. Once the instrument was developed, a pilot study involving 52 students from two Grade 8 science classes was undertaken. Quantitative data were collected from 1,360 students in 78 classes across Grades 8, 9, and 10, in addition to in-depth qualitative information gathered from 10 experienced science teachers and 12 Grade 8 students. Analyses of the data suggest that the survey has strong construct validity when used with lower secondary students. This survey could be practically valuable as a tool for gathering information that may guide classroom teachers in refocusing their teaching practices and help to evaluate the effectiveness of intervention programmes.

The presence of depression symptomatology significantly deteriorates the prognosis for the patient. There are many instruments developed to measure depression and anxiety in clinical trials; however, the suitability of the specific scale for screening these disorders in cardiovascular patients is debatable. The aim of current study is to verify which of the major assessment instruments is the most relevant for the screening evaluation of depression and anxiety in patients with cardiovascular system diseases. The sample studied consisted of 120 patients with stable coronary artery disease (CAD). They did not display serious psychiatric or somatic disorders. To assess depressive and anxiety symptoms we used self-reporting measures (BDI-II, HADS, SSAI/STAI, and PHQ), the results of which were compared to results obtained on the basis of a clinician-rating instrument (HRSD). We found that depressive symptoms assessed on the basis of HRSD, BDI-II, and PHQ-9 were equivalent in results, while the results obtained in HADS-D were significantly lower. Anxiety symptoms were found at approximate levels in HADS, SSAI, and GAD-7. The assessment of somatic symptoms in patients with CAD indicates that 87.5% of the subjects reported somatic symptoms of various intensity. Screening assessment of depression in patients with CAD gives different results depending on the tool used. We found that HADS significantly underestimates the percentage of patients with symptoms of depression in patients with CAD. Assessing anxiety symptoms with the aid of HADS gave outcomes close to the results gained by use of other tools.

Nowadays, mobile technologies are part of everyday life, but the lack of instruments to assess their acceptability for the management of chronic diseases makes their actual adoption for this purpose slow. The objective of this study was to develop a survey instrument for assessing patients' attitude toward and intention to use mobile technology for diabetes mellitus (DM) self-management, as well as to identify sociodemographic characteristics and quality of life factors that affect them. We first conducted the documentation and instrument design phases, which were subsequently followed by the pilot study and instrument validation. Afterward, the instrument was administered 103 patients (median age: 37 years; range: 18-65 years) diagnosed with type 1 or type 2 DM, who accepted to participate in the study. The reliability and construct validity were assessed by computing Cronbach's alpha and using factor analysis, respectively. The instrument included statements about the actual use of electronic devices for DM management, interaction between patient and physician, attitude toward using mobile technology, and quality of life evaluation. Cronbach's alpha was 0.9 for attitude toward using mobile technology and 0.97 for attitude toward using mobile device applications for DM self-management. Younger patients (Spearman's ρ =-0.429; P higher education level (Kendall's τ =0.51; P mobile assistive applications for DM control. Moreover, patients with a higher quality of life presented a significantly more positive attitude toward using modern technology (Spearman's ρ =0.466; P mobile technology for DM self-management. Additionally, we found that even if most of the patients showed positive attitude toward mobile applications, only a moderate level of intention to indeed use them was observed. Moreover, the study indicated that barriers were truthfulness and easiness to use.

The Children's Sleep Comic is a standardized self-report questionnaire for assessing insomnia in children ages 5-11 years. The goal of the present study is to introduce a revised version of this measure and to present psychometrics and a cut-off score. Therefore, the revised Children's Sleep Comic, the Sleep Self Report, the Children's Sleep Habits Questionnaire, and the Child Behavior Checklist were applied to a sample of 393 children and their parents. Of the parents who participated voluntarily, a subsample (n = 176) was interviewed on the phone to diagnose their children with sleep disorders according to the International Classification of Sleep Disorders, if applicable. The results indicated that the Children's Sleep Comic is a reliable self-rating instrument for diagnosing childhood insomnia. Internal consistency was α = 0.83; and convergent and divergent validity were adequate. The child-friendly format can foster a good therapeutic relationship, and thus establish the basis for successful intervention.

Designers’ Professional Identity (DPI) combines social- and self-perceptive awareness through which one is able to identify as a designer. However, self-perception can be different from the expectations associated with an ideal designer, especially during education. Thus, this paper reports...... a survey where self-perceived design skills and expectation are compared at different points in a design education. Findings indicate that changes in mindset modify the alignment between self-perception and expectations, which provides implications for education and for a broader understanding of DPI....

Kryptonate-based instrumentation development for automobile exhaust pollutants. Phase III report: design and construction of four (4) experimental models

International Nuclear Information System (INIS)

Goodman, P.; Donaghue, T.

This phase of the program encompasses the design, construction and evaluation of four (4) prototype instruments for the detection of automobile exhaust pollutant. These instruments employ the radio release mechanism utilized by Panametrics in detection of various trace gases. The prototype instruments are of two (2) designs. One design is operable from a power source supplied by an automobile battery. The second design is operable from 110 volts AC power. Successful evaluation in the laboratory as well as with various automobiles were performed with both type instruments. Scale-up of the quantity of sensor material prepared introduced unexpected problems with respect to detection lifetime which were not satisfactorily resolved within the time and funds available to the program. Nevertheless, a Kryptonate-based instrument using a single detection method for the measurement of hydrocarbons, CO and NO/sub x/ as pollutants by automobile exhausts was shown to be operable with actual automobile exhausts, to provide more than adequate sensitivity for inspection purposes, and to provide response and recovery times for full scale reading in the range 10-15 secs.

A new measure of self-determination, the Self-Determination Inventory: Student Report (Spanish version), has recently been adapted and empirically validated in Spanish language. As it is the first instrument intended to measure self-determination in youth with and without disabilities, there is a need to further explore and strengthen its psychometric analysis based on item response patterns. Through item response theory approach, this study examined item observed distributions across the essential characteristics of self-determination. The results demonstrated satisfactory to excellent item functioning patterns across characteristics, particularly within agentic action domains. Increased variability across items was also found within action-control beliefs dimensions, specifically within the self-realisation subdomain. These findings further support the instrument's psychometric properties and outline future research directions. © 2017 MENCAP and International Association of the Scientific Study of Intellectual and Developmental Disabilities and John Wiley & Sons Ltd.

This study was designed to evaluate the usage patterns of portable listening device (PLD) listeners, and the relationships between self-report measures and long-term dosimetry measures of listening habits. This study used a descriptive correlational design. Participants (N = 52) were 18-29 year old men and women who completed surveys. A randomly assigned subset (N = 24) of participants had their listening monitored by dosimetry for one week. Median weekly noise doses reported and measured through dosimetry were low (9-93%), but 14.3% of participants reported exceeding a 100% noise dose weekly. When measured by dosimetry, 16.7% of participants exceeded a 100% noise dose weekly. The self-report question that best predicted the dosimetry-measured dose asked participants to report listening duration and usual listening level on a visual-analog scale. This study reports a novel dosimetry system that can provide accurate measures of PLD use over time. When not feasible, though, the self-report question described could provide a useful research or clinical tool to estimate exposure from PLD use. Among the participants in this study, a small but substantial percentage of PLD users incurred exposure from PLD use alone that increases their risk of music-induced hearing loss.

Full Text Available In this paper a self-report questionnaire on reading-writing difficulties for adults in Spanish (ATLAS is presented. Studies that use self-report questionnaires as a tool for screening of reading-writing difficulties in adults were reviewed. Two studies were carried out to determine the validity and reliability of ATLAS. The first study was aimed to select the critical items and to assess their reliability and their ability to discriminate. In the second study the assessment reported through the answers to the questionnaire was contrasted with the results of psychometric tests. Results showed that (a items were suitable descriptors for adult difficulties, (b there were significant correlations between self-report scores and reading measures, and (c the items discriminate between good and poor readers. The results of this study demonstrated that ATLAS is a sensitive tool to screen adults with reading difficulties. As a further advantage, ATLAS is an easy-to-use and time-saving instrument.

Full Text Available The aims of the current study were to explore possible gender differences in weight misperception, self-reported physical fitness, and dieting, and to analyze the relationship between these variables and others, such as self-esteem, body appreciation, general mental health, and eating- and body image-related variables among adolescents. In addition, the specific risk for eating disorders was examined, as well as the possible clusters with respect to the risk status. The sample comprised 655 students, 313 females and 342 males, aged 16.22 ± 4.58. Different scales of perceived overweight, self-reported physical fitness and dieting together with the Body Mass Index (BMI were considered along with instruments such as the International Physical Activity Questionnaire (IPAQ, General Health Questionnaire (GHQ-28, Self-Esteem Scale (SES, Body Appreciation Scale (BAS and Eating Disorders Inventory-2 (EDI-2. Since some gender differences were found with respect to these adolescent groups, it is necessary to design prevention programs that not only focus on traditional factors such as BMI or body image, but also on elements like weight perception, self-reported fitness and nutritional education.

Full Text Available The Hugh Davies Collection (HDC at the Science Museum in London comprises 42 items of electronic sound apparatus owned by English experimental musician Hugh Davies (1943–2005, including self-built electro-acoustic musical instruments and modified sound production and manipulation hardware. An early proponent of ‘live electronic music’ (performed live on stage rather than constructed on magnetic tape in a studio, Davies’s DIY approach shaped the development of experimental and improvised musics from the late 1960s onwards. However, his practice has not been widely reported in the literature, hence little information is readily available about the material artefacts that constituted and enabled it. This article provides the first account of the development of Davies’s practice in relation to the objects in the HDC: from the modified electronic sound apparatus used in his early live electronic compositions (among the first of their kind by a British composer; through the ‘instrumental turn’ represented by his first self-built instrument, Shozyg I (1968; to his mature practice, where self-built instruments like Springboard Mk. XI (1974 replaced electronic transformation as the primary means by which Davies explored new and novel sound-worlds. As well as advancing knowledge of Davies’s pioneering work in live electronics and instrument-building and enhancing understanding of the objects in the HDC, this article shows how object biographic and archival methodologies can be combined to provide insight into the ways in which objects (instruments, technologies and practices shape each other over time.

This paper reports the wishes and needs of people with type 2 diabetes (T2DM) for a future information and communication technology (ICT) self-management service to help manage their condition and their everyday life. Diabetes is a chronic disease affecting more and more people and placing increasing demands on health care. The self-management of diabetes includes instrumental and, decision-making skills and skills in managing daily activities, which may be supported by an ICT service. In this study we used a participatory design including two sessions of Future Workshop (FW) as part of a larger research project on the self-management of diabetes. Adults with type 2 diabetes participated in two FW sessions in which their expressed wishes and needs for an ICT service all fell under the broad category of Acceptance of the diagnosis, with three other suggestions; Trust in partnerships, Communication, and Individualized information. The participants' experience of the FW as a democratic process and their appreciation of mutual learning contributed to these results, which are consistent with the aims of person-centred care.

Once a government has defined its environmental goals, it can execute them by means of different policy instruments. The following environmental policy instruments can be distinguished: (1) instruments of social regulation, such as transfer of information (environmental education, environmental labels, environmental impact reports, etc.), self-regulation (environmental policy agreements, self-control), and environmental care systems; (2) instruments of financial aid, such as subsidies, soft loans, and fiscal incentives (investment deduction, tax reduction and tax exemption); (3) instruments of planning such as macro-planning and micro-planning, binding planning and non-binding planning, sectoral planning and non-sectoral planning; (4) instruments of direct regulation, such as permits, prohibitions and restrictions, and different sorts of requirements (quality-demands, product-demands, emission-demands, design demands, construction demands and production demands); (5) instruments of market regulation, such as liability rules, marketable emission rights, deposit and refund system, enforcement incentives and environmental levies. In this contribution, each of these environmental policy instruments is analyzed in general. After that, the instruments which have already been used in European environmental policy are examined. Finally, attention paid to the use of fiscal instruments in European environmental policy. 80 refs.

This study aimed to explore relationships between self-reported outcome of physiotherapy treatment and attitudes toward responsibility for musculoskeletal disorders. A cross-sectional postal survey design was used. Patients (n=615) from an outpatient physiotherapy clinic, who had finished their physiotherapy treatment within the last 6 months were sent a questionnaire that included the Attitudes regarding Responsibility for Musculoskeletal disorders instrument (ARM), self-reported outcome of treatment and sociodemographic data. A total of 279 (45%) completed forms were returned. Multiple logistic regression analysis was used. The patients' scores on the four dimensions of ARM ("responsibility self active," "responsibility out of my hands," "responsibility employer," and "responsibility medical professionals"), controlled for age, sex, education, and physical activity as well as for number of treatments, main treatment, and physiotherapist, were associated with the patients' self-reported treatment outcome. Patients who attributed responsibility more to themselves were more likely (OR 2.37 and over) to report considerable improvement as the outcome of physiotherapy treatment. Because this study was conducted at only one physiotherapy outpatient clinic and had a cross-sectional design, the results should be replicated in other settings. Because patients' attitudes regarding responsibility for musculoskeletal disorders can possibly affect the outcome of physiotherapy treatment, it might be useful to decide whether to systematically try to influence the person's attitude toward responsibility for the management of the disorder or to match treatment to attitude.

Real-time continuous glucose monitoring can help diabetics to control blood sugar levels within the normal range. However, in the process of practical monitoring, the output of real-time continuous glucose monitoring system is susceptible to glucose sensor and environment noise, which will influence the measurement accuracy of the system. Aiming at this problem, a dual-calibration algorithm for the moving-window double-layer filtering algorithm combined with real-time self-compensation calibration algorithm is proposed in this paper, which can realize the signal drift compensation for current data. And a real-time continuous glucose monitoring instrument based on this study was designed. This real-time continuous glucose monitoring instrument consisted of an adjustable excitation voltage module, a current-voltage converter module, a microprocessor and a wireless transceiver module. For portability, the size of the device was only 40 mm × 30 mm × 5 mm and its weight was only 30 g. In addition, a communication command code algorithm was designed to ensure the security and integrity of data transmission in this study. Results of experiments in vitro showed that current detection of the device worked effectively. A 5-hour monitoring of blood glucose level in vivo showed that the device could continuously monitor blood glucose in real time. The relative error of monitoring results of the designed device ranged from 2.22% to 7.17% when comparing to a portable blood meter.

An instrumented capsule is being developed to be able to measure fuel characteristics, such as fuel temperature, internal pressure of fuel rod, fuel elongation, and neutron flux, etc., during the irradiation test of nuclear fuel in HANARO. The instrumented capsule(02F-11K) for measuring and monitoring fuel centerline temperature and neutron flux was designed and manufactured. The instrumented capsule includes three test fuel rods installed thermocouple to measure fuel centerline temperature and three SPNDs (self-powered neutron detector) to monitor the neutron flux. Its stability was verified by out-of-pile performance test, and its safety evaluation was also shown that the safety requirements were satisfied. And then, to verify the design of the instrumented capsule in the test hole, it was successfully irradiated in the test hole of HANARO from March 14, 2003 to June 1, 2003 (53.8 full power days at 24 MWth). During irradiation, the centerline temperature of PWR UO{sub 2} fuel pellets fabricated by KEPCO Nuclear Fuel Company and the neutron flux were continuously measured and monitored. In the year of 2004, 3 test fuel rods and the instrumented capsule(03F-05K) were designed and fabricated to measure fuel centerline temperature, internal pressure of fuel rod, and fuel axial deformation during irradiation test. This capsule is being irradiated in the test hole OR5 of HANARO reactor from April 26, 2004.

The present study addressed convergence between self-report and indirect approaches to assessing dependency. We were moderately successful in validating an implicit measure, which was found to be reliable, orthogonal to 2 self-report instruments, and predictive of external criteria. This study also examined discrepancies between scores on self-report and implicit measures, and has implications for their significance. The possibility that discrepancies themselves are pathological was not supported, although discrepancies were associated with particular personality profiles. Finally, this study offered additional evidence for the relation between dependency and depressive symptomatology and identified implicit dependency as contributing unique variance in predicting past major depression.

Assessing the Accuracy of Self-Reported Self-Talk

Directory of Open Access Journals (Sweden)

Thomas M. Brinthaupt

2015-05-01

Full Text Available Self-Talk Scale (STS; Brinthaupt, Hein, & Kramer, 2009 is a self-report measure of self-talk frequency that has been shown to possess acceptable reliability and validity. However, no research using the STS has examined the accuracy of respondents’ self-reports. In the present paper, we report a series of studies directly examining the measurement of self-talk frequency and functions using the STS. The studies examine ways to validate self-reported self-talk by (1 comparing STS responses from 6 weeks earlier to recent experiences that might precipitate self-talk, (2 using experience sampling methods to determine whether STS scores are related to recent reports of self-talk over a period of a week, and (3 comparing self-reported STS scores to those provided by a significant other who rated the target on the STS. Results showed that (1 overall self-talk scores, particularly self-critical and self-reinforcing self-talk, were significantly related to reports of context-specific self-talk; (2 high STS scorers reported talking to themselves significantly more often during recent events compared to low STS scorers, and, contrary to expectations, (3 friends reported less agreement than strangers in their self-other self-talk ratings. Implications of the results for the validity of the STS and for measuring self-talk are presented.

A new design of neutron survey instrument

International Nuclear Information System (INIS)

Tanner, R.J.; Eakins, J.S.; Hager, L.G.

2010-01-01

A novel design of neutron survey instrument has been developed. The moderator has been modified via the use of 'neutron guides', which help thermal neutrons reach the central proportional counter. This innovation has allowed the variations in the energy dependence of ambient dose equivalent response to be reduced compared to prior single-detector designs, whilst maintaining a relatively light moderator and simple construction. In particular, the design has a relatively small over-response to neutrons with energies around 5 keV, when compared to prior designs. The final optimized design has been verified using MCNP5 calculations to ensure that the response is relatively independent of the energy and direction of the incident neutron. This has required the ends of the guides to be structured so that unidirectional and isotropic neutron fields have closely matched responses, as is necessary in the workplace. The reading of the instrument in workplace fields is calculated via folding and the suitability of the design for use in the workplace discussed.

Design type testing for digital instrumentation and control systems

Bastl, W.; Mohns, G.

The design type qualification of digital safety instrumentation and control is outlined. Experience shows that the concepts discussed, derived from codes, guidelines and standards, achieve useful results. It has likewise become clear that the systematics of design type qualification of the hardware components is also applicable to the software components. Design type qualification of the software, a premiere, could be performed unexpectedly smoothly. The hardware design type qualification proved that the hardware as a substrate of functionality and reliability is an issue that demands full attention, as compared to conventional systems. Another insight is that design qualification of digital instrumentation and control systems must include plant-independent systems tests. Digital instrumentation and control systems simply work very differently from conventional control systems, so that this testing modality is inevitable. (Orig./CB) [de

The International Design Study for the Neutrino Factory (the IDS-NF) was established by the community at the ninth "International Workshop on Neutrino Factories, super-beams, and beta- beams" which was held in Okayama in August 2007. The IDS-NF mandate is to deliver the Reference Design Report (RDR) for the facility on the timescale of 2012/13. In addition, the mandate for the study [3] requires an Interim Design Report to be delivered midway through the project as a step on the way to the RDR. This document, the IDR, has two functions: it marks the point in the IDS-NF at which the emphasis turns to the engineering studies required to deliver the RDR and it documents baseline concepts for the accelerator complex, the neutrino detectors, and the instrumentation systems. The IDS-NF is, in essence, a site-independent study. Example sites, CERN, FNAL, and RAL, have been identified to allow site-specific issues to be addressed in the cost analysis that will be presented in the RDR. The choice of example sites shou...

Designers employ a range of tools in most design projects, yet there are few frameworks for understanding how and why they work. On the basis of a well-established school of thought, pragmatism, this paper contributes with a coherent conceptualisation of tools in design, which I label instruments...... of inquiry. This perspective underscores the crucial role that instruments play in design, and the ways in which they scaffold design creativity and exploration. In particular, it highlights that instruments not only augment our capabilities for carrying out intended actions, they also guide our perception...... and understanding of design problems and solutions. I present and discuss a framework consisting of five qualities of instruments of inquiry, which make them valuable in designerly inquiry: perception, conception, externalisation, knowing-through-action, and mediation....

Standards for Instrument Migration When Implementing Paper Patient-Reported Outcome Instruments Electronically: Recommendations from a Qualitative Synthesis of Cognitive Interview and Usability Studies.

Muehlhausen, Willie; Byrom, Bill; Skerritt, Barbara; McCarthy, Marie; McDowell, Bryan; Sohn, Jeremy

2018-01-01

To synthesize the findings of cognitive interview and usability studies performed to assess the measurement equivalence of patient-reported outcome (PRO) instruments migrated from paper to electronic formats (ePRO), and make recommendations regarding future migration validation requirements and ePRO design best practice. We synthesized findings from all cognitive interview and usability studies performed by a contract research organization between 2012 and 2015: 53 studies comprising 68 unique instruments and 101 instrument evaluations. We summarized study findings to make recommendations for best practice and future validation requirements. Five studies (9%) identified minor findings during cognitive interview that may possibly affect instrument measurement properties. All findings could be addressed by application of ePRO best practice, such as eliminating scrolling, ensuring appropriate font size, ensuring suitable thickness of visual analogue scale lines, and providing suitable instructions. Similarly, regarding solution usability, 49 of the 53 studies (92%) recommended no changes in display clarity, navigation, operation, and completion without help. Reported usability findings could be eliminated by following good product design such as the size, location, and responsiveness of navigation buttons. With the benefit of accumulating evidence, it is possible to relax the need to routinely conduct cognitive interview and usability studies when implementing minor changes during instrument migration. Application of design best practice and selecting vendor solutions with good user interface and user experience properties that have been assessed in a representative group may enable many instrument migrations to be accepted without formal validation studies by instead conducting a structured expert screen review.

The use of valid and reliable instruments for assessing self-care is crucial for the evaluation of chronic obstructive pulmonary disease (COPD) management programs. The aim of this review is to evaluate the measurement properties and theoretical foundations of instruments for assessing self-care and related concepts in people with COPD. A systematic review was conducted of articles describing the development and validation of self-care instruments. The methodological quality of the measurement properties was assessed using the COSMIN checklist. Ten studies were included evaluating five instruments: three for assessing self-care and self-management and two for assessing self-efficacy. The COPD Self-Efficacy Scale was the most studied instrument, but due to poor study methodological quality, evidence about its measurement properties is inconclusive. Evidence from the COPD Self-Management Scale is more promising, but only one study tested its properties. Due to inconclusive evidence of their measurement properties, no instrument can be recommended for clinical use. Copyright © 2016 Elsevier Inc. All rights reserved.

There is a paucity of valid, brief instruments for the assessment of lifetime major depressive disorder (MDD) that can be used in, for example, large-scale genomics, imaging or biomarker studies on depression. We developed the LIfetime Depression Assessment Self-report (LIDAS), which assesses lifetime MDD diagnosis according to DSM criteria, and is largely based on the widely used Composite International Diagnostic Interview (CIDI). Here, we tested the feasibility and determined the sensitivity and specificity for measuring lifetime MDD with this new questionnaire, with a regular CIDI as reference. Sensitivity and specificity analyses of the online lifetime MDD questionnaire were performed in adults with (n = 177) and without (n = 87) lifetime MDD according to regular index CIDIs, selected from the Netherlands Study of Depression and Anxiety (NESDA) and Netherlands Twin Register (NTR). Feasibility was tested in an additional non-selective, population-based sample of NTR participants (n = 245). Of the 753 invited persons, 509 (68%) completed the LIDAS, of which 419 (82%) did this online. User-friendliness of the instrument was rated high. Median completion time was 6.2 min. Sensitivity and specificity for lifetime MDD were 85% [95% confidence interval (CI) 80-91%] and 80% (95% CI 72-89%), respectively. This LIDAS instrument gave a lifetime MDD prevalence of 20.8% in the population-based sample. Measuring lifetime MDD with an online instrument was feasible. Sensitivity and specificity were adequate. The instrument gave a prevalence of lifetime MDD in line with reported population prevalences. LIDAS is a promising tool for rapid determination of lifetime MDD status in large samples, such as needed for genomics studies.

Readability and comprehension of self-report binge eating measures.

Richards, Lauren K; McHugh, R Kathryn; Pratt, Elizabeth M; Thompson-Brenner, Heather

2013-04-01

The validity of self-report binge eating instruments among individuals with limited literacy is uncertain. This study aims to evaluate reading grade level and multiple domains of comprehension of 13 commonly used self-report assessments of binge eating for use in low-literacy populations. We evaluated self-report binge eating measures with respect to reading grade levels, measure length, formatting and linguistic problems. All measures were written at a reading grade level higher than is recommended for patient materials (above the 5th to 6th grade level), and contained several challenging elements related to comprehension. Correlational analyses suggested that readability and comprehension elements were distinct contributors to measure difficulty. Individuals with binge eating who have low levels of educational attainment or limited literacy are often underrepresented in measure validation studies. Validity of measures and accurate assessment of symptoms depend on an individual's ability to read and comprehend instructions and items, and these may be compromised in populations with lower levels of literacy.

This report, Volume IV of the International Linear Collider Reference Design Report, describes the detectors which will record and measure the charged and neutral particles produced in the ILC's high energy e+e- collisions. The physics of the ILC, and the environment of the machine-detector interface, pose new challenges for detector design. Several conceptual designs for the detector promise the needed performance, and ongoing detector R&D is addressing the outstanding technological issues. Two such detectors, operating in push-pull mode, perfectly instrument the ILC interaction region, and access the full potential of ILC physics.

Purpose: To enable to provide design aid for the nuclear power plant instrumentation of high reliability with the minimum cost while eliminating unrequired condition even if there are no data for the ground of the instrumentation design. Constitution: The information data base for the design of process radiation ray monitors are administrated by a data base administration device. The conditions to be satisfied in the process radiation monitors designed based on the data for the circumstances where particular predetermined process radiation monitors are installed, are derived by deduction using information obtained from the data base by way of the data base administration device. The derived design conditions are displayed and the optimum conditions are again reduced and displayed. In this way, the designers are assisted such that optimum designs can be obtained while sufficiently satisfying the safety and also in view of the cost. (Kamimura, M.)

2005-01-01

This report presents the results of the Westinghouse work performed under Task 1 of this Financial Assistance Award and satisfies a Level 2 Milestone for the project. While most of the signals required for control of IPSRs are typical of other PWRs, the integral configuration poses some new challenges in the design or deployment of the sensors/instrumentation and, in some cases, requires completely new approaches. In response to this consideration, the overall objective of Task 1 was to establish the instrumentation needs for integral reactors, provide a review of the existing solutions where available, and, identify research and development needs to be addressed to enable successful deployment of IPSRs. The starting point for this study was to review and synthesize general characteristics of integral reactors, and then to focus on a specific design. Due to the maturity of its design and availability of design information to Westinghouse, IRIS (International Reactor Innovative and Secure) was selected for this purpose. The report is organized as follows. Section 1 is an overview. Section 2 provides background information on several representative IPSRs, including IRIS. A review of the IRIS safety features and its protection and control systems is used as a mechanism to ensure that all critical safety-related instrumentation needs are addressed in this study. Additionally, IRIS systems are compared against those of current advanced PWRs. The scope of this study is then limited to those systems where differences exist, since, otherwise, the current technology already provides an acceptable solution. Section 3 provides a detailed discussion on instrumentation needs for the representative IPSR (IRIS) with detailed qualitative and quantitative requirements summarized in the exhaustive table included as Appendix A. Section 3 also provides an evaluation of the current technology and the instrumentation used for measurement of required parameters in current PWRs. Section 4

There exists a need for designers and developers to have a method to conveniently test a variety of communications parameters for an overall system design. This is no different when testing network protocols as when testing modulation formats. In this report, we discuss a means of providing a networking test device specifically designed to be used for space communications. This test device is a PC-based Virtual Instrument (VI) programmed using the LabVIEW(TM) version 5 software suite developed by National Instruments(TM)TM. This instrument was designed to be portable and usable by others without special, additional equipment. The programming was designed to replicate a VME-based hardware module developed earlier at New Mexico State University (NMSU) and to provide expanded capabilities exceeding the baseline configuration existing in that module. This report describes the design goals for the VI module in the next section and follows that with a description of the design of the VI instrument. This is followed with a description of the validation tests run on the VI. An application of the error-generating VI to networking protocols is then given.

Design of virtual three-dimensional instruments for sound control

Science.gov (United States)

Mulder, Axel Gezienus Elith

An environment for designing virtual instruments with 3D geometry has been prototyped and applied to real-time sound control and design. It enables a sound artist, musical performer or composer to design an instrument according to preferred or required gestural and musical constraints instead of constraints based only on physical laws as they apply to an instrument with a particular geometry. Sounds can be created, edited or performed in real-time by changing parameters like position, orientation and shape of a virtual 3D input device. The virtual instrument can only be perceived through a visualization and acoustic representation, or sonification, of the control surface. No haptic representation is available. This environment was implemented using CyberGloves, Polhemus sensors, an SGI Onyx and by extending a real- time, visual programming language called Max/FTS, which was originally designed for sound synthesis. The extension involves software objects that interface the sensors and software objects that compute human movement and virtual object features. Two pilot studies have been performed, involving virtual input devices with the behaviours of a rubber balloon and a rubber sheet for the control of sound spatialization and timbre parameters. Both manipulation and sonification methods affect the naturalness of the interaction. Informal evaluation showed that a sonification inspired by the physical world appears natural and effective. More research is required for a natural sonification of virtual input device features such as shape, taking into account possible co- articulation of these features. While both hands can be used for manipulation, left-hand-only interaction with a virtual instrument may be a useful replacement for and extension of the standard keyboard modulation wheel. More research is needed to identify and apply manipulation pragmatics and movement features, and to investigate how they are co-articulated, in the mapping of virtual object

The Sentinel-5 instrument is currently under development by a consortium led by Airbus Defence and Space in the frame of the European Union Copernicus program. It is a customer furnished item to the MetOp Second Generation satellite platform, which will provide operational meteorological data for the coming decades. Mission objective of the Sentinel-5 is to monitor the composition of the Earth atmosphere for Copernicus Atmosphere Services by taking measurements of trace gases and aerosols impacting air quality and climate with high resolution and daily global coverage. Therefore the Sentinel-5 provides five dispersive spectrometers covering the UV-VIS (270…500 nm), NIR (685 …773 nm) and SWIR (1590…1675 and 2305…2385 nm) spectral bands with resolutions <=1nm. Spatially the Sentinel-5 provides a 108° field of view with a ground sampling of 7.5 x 7 km2 at Nadir. The development program is post PDR and the build-up of the industrial team is finalised. We report on the instrument architecture and design derived from the driving requirements, the predicted instrument performance, and the general status of the program.

2016-01-01

Documentation of clinical outcomes is increasingly expected in delivery of prosthetic services and devices. However, many outcome measures suitable for use in clinical care and research have not been psychometrically tested with prosthesis users. The aim of this study was to determine test-retest reliability, mode-of-administration (MoA) equivalence, standard error of measurement (SEM), and minimal detectable change (MDC) of standardized, self-report instruments that assess constructs of importance to people with lower limb loss. Prosthesis users (n = 201) were randomly assigned to groups based on MoA (i.e., paper, electronic, or mixed-mode). Participants completed two surveys 2 to 3 d apart. Instruments included the Prosthetic Limb Users Survey of Mobility, Prosthesis Evaluation Questionnaire-Mobility Subscale, Activities-Specific Balance Confidence Scale, Quality of Life in Neurological Conditions-Applied Cognition/General Concerns, Patient-Reported Outcomes Measurement Information System Profile, and Socket Comfort Score. Intraclass correlation coefficients indicated all instruments are appropriate for group-level comparisons and select instruments are suitable for individual-level applications. Several instruments showed evidence of possible floor and ceiling effects. All were equivalent across MoAs. SEM and MDC were quantified to facilitate interpretation of outcomes and change scores. These results can enhance clinicians' and researchers' ability to select, apply, and interpret scores from instruments administered to prosthesis users.

2015-01-01

This study examined the association of self-efficacy and self-regulation with nutrition and exercise behaviors. The study used a cross-sectional design and included 108 participants (54 men, 54 women). Nutrition behaviors (fruit/vegetable consumption, dinner cooking, and restaurant eating) and exercise were measured using total days in last week a behavior was reported. Instruments measuring self-efficacy and self-regulation demonstrated excellent Cronbach's alphas (.93-.95). Path analysis indicated only fruit/vegetable consumption and exercise were associated with self-efficacy and self-regulation. Self-regulation showed direct association with fruit/vegetable consumption and exercise, but self-efficacy had direct association only with exercise. Self-efficacy and self-regulation should be strategically used to promote health behaviors.

The development and validation of the Self-Efficacy Beliefs about Equitable Science Teaching and learning instrument for prospective elementary teachers

Ritter, Jennifer M.

1999-12-01

The purpose of this study was to develop, validate and establish the reliability of an instrument to assess the self-efficacy beliefs of prospective elementary teachers with regards to science teaching and learning for diverse learners. The study used Bandura's theoretical framework, in that the instrument would use the self-efficacy construct to explore the beliefs of prospective elementary science teachers with regards to science teaching and learning to diverse learners: specifically the two dimensions of self-efficacy beliefs defined by Bandura (1977): personal self-efficacy and outcome expectancy. A seven step plan was designed and followed in the process of developing the instrument, which was titled the Self-Efficacy Beliefs about Equitable Science Teaching or SEBEST. Diverse learners as recognized by Science for All Americans (1989) are "those who in the past who have largely been bypassed in science and mathematics education: ethnic and language minorities and girls" (p. xviii). That definition was extended by this researcher to include children from low socioeconomic backgrounds based on the research by Gomez and Tabachnick (1992). The SEBEST was administered to 226 prospective elementary teachers at The Pennsylvania State University. Using the results from factor analyses, Coefficient Alpha, and Chi-Square a 34 item instrument was found to achieve the greatest balance across the construct validity, reliability and item balance with the content matrix. The 34 item SEBEST was found to load purely on four factors across the content matrix thus providing evidence construct validity. The Coefficient Alpha reliability for the 34 item SEBEST was .90 and .82 for the PSE sub-scale and .78 for the OE sub-scale. A Chi-Square test (X2 = 2.7 1, df = 7, p > .05) was used to confirm that the 34 items were balanced across the Personal Self-Efficacy/Outcome Expectancy and Ethnicity/LanguageMinority/Gender Socioeconomic Status/dimensions of the content matrix.

To make a recommendation on the "best" instrument to assess attitudes toward and/or capabilities regarding self-management of osteoarthritis (OA) based on available measurement property evidence. Electronic searches were performed in MEDLINE, EMBASE, CINAHL and PsychINFO (inception to 27 December 2016). Two reviewers independently rated measurement properties using the Consensus-based Standards for the selection of Health Measurement Instruments (COSMIN) 4-point scale. Best evidence synthesis was determined by considering COSMIN ratings for measurement property results and the level of evidence available for each measurement property of each instrument. Eight studies out of 5653 publications met the inclusion criteria, with eight instruments identified for evaluation: Multidimensional Health Locus of Control (MHLC), Perceived Behavioural Control (PBC), Patient Activation Measure (PAM), Educational Needs Assessment (ENAT), Stages of Change Questionnaire in Osteoarthritis (SCQOA), Effective Consumer Scale (EC-17) and Perceived Efficacy in Patient-Physician Interactions five item (PEPPI-5) and ten item scales. Measurement properties assessed for these instruments included internal consistency (k = 8), structural validity (k = 8), test-retest reliability (k = 2), measurement error (k = 1), hypothesis testing (k = 3) and cross-cultural validity (k = 3). No information was available for content validity, responsiveness or minimal important change (MIC)/minimal important difference (MID). The Dutch PEPPI-5 demonstrated the best measurement property evidence; strong evidence for internal consistency and structural validity but limited evidence for reliability and construct validity.

This study aims to measure the validity and reliability of Turkish male breast self-examination (MBSE) instrument. The methodological study was performed in 2016 at Ege University, Faculty of Nursing, İzmir, Turkey. The MBSE includes ten steps. For validity studies, face validity, content validity, and construct validity (exploratory factor analysis) were done. For reliability study, Kuder Richardson was calculated. The content validity index was found to be 0.94. Kendall W coefficient was 0.80 (p=0.551). The total variance explained by the two factors was found to be 63.24%. Kuder Richardson 21 was done for reliability study and found to be 0.97 for the instrument. The final instrument included 10 steps and two stages. The Turkish version of MBSE is a valid and reliable instrument for early diagnose. The MBSE can be used in Turkish speaking countries and cultures with two stages and 10 steps.

2010-12-01

this study was designed to improve the measurement of financial exploitation (FE) by testing psychometric properties of the older adult financial exploitation measure (OAFEM), a client self-report instrument. rasch item response theory and traditional validation approaches were used. Questionnaires were administered by 22 adult protective services investigators from 7 agencies in Illinois to 227 substantiated abuse clients. Analyses included tests for dimensionality, model fit, and additional construct validation. Results from the OAFEM were also compared with the substantiation decision of abuse and with investigators' assessments of FE using a staff report version. Hypotheses were generated to test hypothesized relationships. the OAFEM, including the original 79-, 54-, and 30-item measures, met stringent Rasch analysis fit and unidimensionality criteria and had high internal consistency and item reliability. The validation results were supportive, while leading to reconsideration of aspects of the hypothesized theoretical hierarchy. Thresholds were suggested to demonstrate levels of severity. the measure is now available to aid in the assessment of FE of older adults by both clinicians and researchers. Theoretical refinements developed using the empirically generated item hierarchy may help to improve assessment and intervention.

The use of non-instrumented capsule designed and fabricated in this time is for the evaluation of material irradiation performance, it is to be installed in the inner core of HANARO. The design process of non-instrumented capsule was accomplished by the decision of the quality of material and the shape, thermal analysis, structural analysis. The temperature of the specimen and the stress in capsule during irradiation test was calculated by the thermal analysis and the structural analysis. GGENGTC code and ABAQUS code were used for the calculation of non-instrumented capsule. In case of installing the capsule in irradiation hole, the coolant flow rate and the pressure drop in the hole is changed, which will affect the coolant flow rate of the fuel region. Eventually the coolant flow rate outside capsule have to be restricted to the allowable range. In order to obtain the required pressure drop, the flow rate control mechanism, end plate and orifice ring were used in this test. The test results are compared with 36-element fuel pressure drop data which AECL performed by the SCTR facility.

The Nurses Self-Concept Instrument (NSCI): assessment of psychometric properties for Australian domestic and international student nurses.

Science.gov (United States)

Angel, Elizabeth; Craven, Rhonda; Denson, Nida

2012-07-01

Professional self-concept is a critical driver of job satisfaction. In Australia, as international nursing enrolments rise, nursing is increasingly characterised by a professional body of international nurses who may differ from domestic Australian nurses in their nursing self-concept. At present, no psychometrically sound instrument for assessing nursing self-concept for Australian domestic and international nursing students is available. The purpose of this study was to: (1) develop an instrument (the Nurses' Self-Concept Instrument (NSCI)) to measure the professional self-concept of domestic and international nursing students in Australia, and (2) test the psychometric properties of this newly developed instrument. A literature review was conducted to generate the initial dimension and item pools to measure nurses' professional self-concept (NSCI). Two stakeholders examined the content and face validity of dimensions and items. Analysis was performed on data collected from 253 undergraduate nursing students in a large public university in Sydney, Australia, and consisted of domestic (n=218) and international (n=35) nursing students. Internal reliability was assessed using Cronbach's Alpha. Confirmatory factor analysis (CFA) was used to assess the construct validity of the NSCI. The resulting NSCI consisted of 14 items across four self-concept domains: care, leadership, staff relations, and knowledge. The CFA supported the hypothesised factor structure of the self-concept model. All reliabilities were acceptable for both domestic and international students (ranging from r=.78 to .93). The NSCI was shown to be a valid and reliable tool for assessing Australian domestic and international student nurses' professional self-concept. This instrument may also enable those responsible for recruitment of students into nursing courses to assess students' professional self-concept and implement appropriate strategies to foster the growth of lifelong career development

To study the prevalence and correlates of self-reported ADHD symptoms among school-going adolescents from Kerala, India. Seven thousand five hundred sixty students from Classes 8, 10, and 12, aged 12 to 19 years, across 73 schools selected by cluster random sampling, were invited to participate, but only 7,150 successfully completed the questionnaire incorporating standardized instruments. Three hundred five (4.3%) self-reported symptoms for ADHD combined type, 131 (1.8%) for ADHD hyperactive-impulsive type, and 102 (1.4%) for ADHD inattentive type with a male predominance. Binary logistic regression analysis showed that those with symptoms of ADHD (combined type) compared with the non-ADHD group had poorer academic performance, significantly higher substance use, psychological distress, suicidality, and sexual abuse. The high prevalence of self-reported ADHD symptoms and its association with negative correlates previously reported in literature in those with a diagnosis of ADHD suggests that clinically significant self-reported ADHD symptoms could be as disabling as ADHD. © The Author(s) 2016.

Despite the health benefits associated with children's sport participation, the occurrence of injury in this context is common. The extent to which sport injuries impact children's ongoing involvement in sport is largely unknown. Surveys have been shown to be useful for collecting children's injury and sport participation data; however, there are currently no published instruments which investigate the impact of injury on children's sport participation. This study describes the processes undertaken to assess the validity of two survey instruments for collecting self-reported information about child cricket and netball related participation, injury history and injury risk perceptions, as well as the reliability of the cricket-specific version. Face and content validity were assessed through expert feedback from primary and secondary level teachers and from representatives of peak sporting bodies for cricket and netball. Test-retest reliability was measured using a sample of 59 child cricketers who completed the survey on two occasions, 3-4 weeks apart. Based on expert feedback relating to face and content validity, modification and/or deletion of some survey items was undertaken. Survey items with low test-retest reliability (κ≤0.40) were modified or deleted, items with moderate reliability (κ=0.41-0.60) were modified slightly and items with higher reliability (κ≥0.61) were retained, with some undergoing minor modifications. This is the first survey of its kind which has been successfully administered to cricketers aged 10-16 years to collect information about injury risk perceptions and intentions for continued sport participation. Implications for its generalisation to other child sport participants are discussed. Copyright © 2010 Sports Medicine Australia. Published by Elsevier Ltd. All rights reserved.

2005-11-01

This report summarizes technical progress April-September 2005 on the Phase II program ''On-Line Self-Calibrating Single Crystal Sapphire Optical Sensor Instrumentation for Accurate and Reliable Coal Gasifier Temperature Measurement'', funded by the Federal Energy Technology Center of the U.S. Department of Energy, and performed by the Center for Photonics Technology of the Bradley Department of Electrical and Computer Engineering at Virginia Tech. The outcome of the first phase of this program was the selection of broadband polarimetric differential interferometry (BPDI) for further prototype instrumentation development. This approach is based on the measurement of the optical path difference (OPD) between two orthogonally polarized light beams in a single-crystal sapphire disk. The objective of this program is to bring the sensor technology, which has already been demonstrated in the laboratory, to a level where the sensor can be deployed in the harsh industrial environments and will become commercially viable. Due to the difficulties described on the last report, field testing of the BPDI system has not continued to date. However, we have developed an alternative high temperature sensing solution, which is described in this report. The sensing system will be installed and tested at TECO's Polk Power Station. Following a site visit in June 2005, our efforts have been focused on preparing for that field test, including he design of the sensor mechanical packaging, sensor electronics, the data transfer module, and the necessary software codes to accommodate this application.. We are currently ready to start sensor fabrication.

Intensive workload and limited training opportunities for Irish non-consultant hospital doctors (NCHDs) has a negative effect on their health and well-being, and can result in burnout. Burnout affects physician performance and can lead to medical errors. This study examined the prevalence of burnout syndrome among Irish NCHDs and its association with self-reported medical error and poor quality of patient care. A cross-sectional quantitative survey-based design. All teaching hospitals affiliated with University College Cork. NCHDs of all grades and specialties. The following instruments were completed by all participants: Maslach Burnout Inventory-Human Service Survey (MBI-HSS), assessing three categories of burnout syndrome: Emotional exhaustion (EE), Personal Achievement (PA) and Depersonalization (DP); questions related to self-reported medical errors/poor patient care quality and socio-demographic information. Self-reported measures of burnout and poor quality of patient care. Prevalence of burnout among physicians (n = 265) was 26.4%. There was a significant gender difference for EE and DP, but none for PA. A positive weak correlation was observed between EE and DP with medical error or poor patient care. A negative association was reported between PA and medical error and reduced quality of patient care. Burnout is prevalent among NCHDs in Ireland. Burnout syndrome is associated with self-reported medical error and quality of care in this sample population. Measures need to be taken to address this issue, with a view to protecting health of NCHDs and maintaining quality of patient care. © The Author 2017.

Laparoscopic surgery techniques have been demonstrated to provide massive benefits to patients. However, surgeons are subjected to hardworking conditions because of the poor ergonomic design of the instruments. In this article, a new ergonomic handle design is presented. This handle is designed using ergonomic principles, trying to provide both more intuitive manipulation of the instrument and a shape that reduces the high-pressure zones in the contact with the surgeon's hand. The ergonomic characteristics of the new handle were evaluated using objective and subjective studies. The experimental evaluation was performed using 28 volunteers by means of the comparison of the new handle with the ring-handle (RH) concept in an instrument available on the market. The volunteers' muscle activation and motions of the hand, wrist, and arm were studied while they performed different tasks. The data measured in the experiment include electromyography and goniometry values. The results obtained from the subjective analysis reveal that most volunteers (64%) preferred the new prototype to the RH, reporting less pain and less difficulty to complete the tasks. The results from the objective study reveal that the hyperflexion of the wrist required for the manipulation of the instrument is strongly reduced. The new ergonomic handle not only provides important ergonomic advantages but also improves the efficiency when completing the tasks. Compared with RH instruments, the new prototype reduced the high-pressure areas and the extreme motions of the wrist. Copyright © 2014 Elsevier Inc. All rights reserved.

Self-reported Discrimination and Depressive Symptoms Among Older Chinese Adults in Chicago.

Li, Lydia W; Dong, XinQi

2017-07-01

Discrimination is part of life for many Americans, especially ethnic minorities. Focusing on older Chinese Americans, this study examines the association between self-reported discrimination and depressive symptoms and identifies subgroups that are more likely to report experiencing discrimination. We conducted cross-sectional analysis of data collected from adults (age 60+ years) of Chinese origin residing in the Greater Chicago area (N = 3,004). Self-reported discrimination was assessed by the Experiences of Discrimination instrument and was dichotomized (yes vs no). Depressive symptoms were measured by the Patient Health Questionnaire (PHQ-9). Logistic regression of self-reported discrimination and negative binominal regression of depressive symptoms were conducted. About 21.5% of the sample reported having experienced discrimination. The odds of reporting discrimination are higher for those who are younger, have higher education and income, are more acculturated, have been in the United States longer, live outside Chinatown, and have higher levels of neuroticism and conscientiousness. Self-reported discrimination is significantly and positively associated with depressive symptoms, independent of sociodemographic characteristics, migration-related variables, and personality factors. Findings suggest a robust relationship between self-reported discrimination and depressive symptoms in older Chinese Americans. They further suggest that the relatively advantaged groups-younger, higher socioeconomic status, more acculturated, and living outside Chinatown-are more likely to report experiencing discrimination. © The Author 2017.

The following report serves as a formal introduction to the water-based Natural convection Shutdown heat removal Test Facility (NSTF) program at Argonne. Since 2005, this US Department of Energy (DOE) sponsored program has conducted large scale experimental testing to generate high-quality and traceable validation data for guiding design decisions of the Reactor Cavity Cooling System (RCCS) concept for advanced reactor designs. The most recent facility iteration, and focus of this report, is the operation of a 1/2 scale model of a water-RCCS concept. Several features of the NSTF prototype align with the conceptual design that has been publicly released for the AREVA 625 MWt SC-HTGR. The design of the NSTF also retains all aspects common to a fundamental boiling water thermosiphon, and thus is well poised to provide necessary experimental data to advance basic understanding of natural circulation phenomena and contribute to computer code validation. Overall, the NSTF program operates to support the DOE vision of aiding US vendors in design choices of future reactor concepts, advancing the maturity of codes for licensing, and ultimately developing safe and reliable reactor technologies. In this report, the top-level program objectives, testing requirements, and unique considerations for the water cooled test assembly are discussed, and presented in sufficient depth to support defining the program’s overall scope and purpose. A discussion of the proposed 6-year testing program is then introduced, which outlines the specific strategy and testing plan for facility operations. The proposed testing plan has been developed to meet the toplevel objective of conducting high-quality test operations that span across a broad range of single- and two-phase operating conditions. Details of characterization, baseline test cases, accident scenario, and parametric variations are provided, including discussions of later-stage test cases that examine the influence of geometric

1984-05-01

This Design Report describes the plans for the construction of the second detector for the SLAC Linear Collider to study e + e - collisions at energies of up to 100 GeV in the center-of-mass. Particle tracking and momentum measurement are provided by a vertex detector, a high-precision central drift chamber, and pairs of endcap drift chambers, all in a 1 Tesla magnetic field produced by a superconducting solenoid. Particle identification is provided by CRIDs (Cerenkov Ring Imaging Detectors). Calorimetry is done in two parts; a liquid argon calorimeter (LAC) with uranium and iron radiators is located inside the coil, and the laminated iron of the flux return is instrumented with limited-streamer-mode tubes to complete the hadron calorimetry. The streamer tubes of this warm-iron calorimeter, called the WIC, are instrumented with strip readout to provide muon tracking in addition to calorimetry. The same technology is used on the end structures of the detector and the central region, thus providing uniform response in both regions

2014-07-01

Patients suffering from chronic obstructive pulmonary disease (COPD) experience problems in the performance of activities of daily living (ADL) tasks. The objective was to examine the self-reported quality of ADL task performance among COPD patients, and to investigate whether age, gender, and routine COPD characteristics correlate with the self-reported ADL ability. Eighty patients admitted to hospital with COPD exacerbations participated. In a cross-sectional study, the patients' self-reported ADL ability was assessed using the ADL-Interview (ADL-I) instrument. Data concerning age, gender, and routine COPD characteristics were drawn from the patients' medical records. The patients reported being inefficient to markedly inefficient when performing ADL tasks within the personal hygiene, toileting, dressing, household, mobility, and transportation domains. While more than 90% of the participants reported increased effort and/or fatigue when performing the ADL tasks, up to 88% of the participants relied on help from others in the performance of general household chores like cooking and shopping. Self-reported ADL ability did not correlate with age, gender, or routine COPD characteristics. Decreased quality of ADL task performance seemed to be extremely common among COPD patients. Therefore, addressing the problems in individually tailored pulmonary rehabilitation programmes may be advantageous.

To identify, critically appraise and summarize the measurement properties of instruments to assess self-care in healthy children. Assessing self-care is a proper consideration for nursing practice and nursing research. No systematic review summarizes instruments of measurement validated in healthy children. Psychometric review in accordance with the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) panel. MEDLINE, CINAHL, PsycINFO, Web of Science and Open Grey were searched from their inception to December 2016. Validation studies with a healthy child population were included. Search was not restricted by language. Two reviewers independently assessed the methodological quality of included studies using the COSMIN checklist. Eleven studies were included in the review assessing the measurement properties of ten instruments. There was a maximum of two studies per instrument. None of the studies evaluated the properties of test-retest reliability, measurement error, criterion validity and responsiveness. Internal consistency and structural validity were rated as "excellent" or "good" in four studies. Four studies were rated as "excellent" in content validity. Cross-cultural validity was rated as "poor" in the two studies (three instruments) which cultural adaptation was carried out. The evidence available does not allow firm conclusions about the instruments identified in terms of reliability and validity. Future research should focus on generate evidence about a wider range of measurement properties of these instruments using a rigorous methodology, as well as instrument testing on different countries and child population. © 2017 John Wiley & Sons Ltd.

Key issues in the thermal design of spaceborne cryogenic infrared instruments

Science.gov (United States)

Schember, Helene R.; Rapp, Donald

1992-12-01

Thermal design and analysis play an integral role in the development of spaceborne cryogenic infrared (IR) instruments. From conceptual sketches to final testing, both direct and derived thermal requirements place significant constraints on the instrument design. Although in practice these thermal requirements are interdependent, the sources of most thermal constraints may be grouped into six distinct categories. These are: (1) Detector temperatures, (2) Optics temperatures, (3) Pointing or alignment stability, (4) Mission lifetime, (5) Orbit, and (6) Test and Integration. In this paper, we discuss these six sources of thermal requirements with particular regard to development of instrument packages for low background infrared astronomical observatories. In the end, the thermal performance of these instruments must meet a set of thermal requirements. The development of these requirements is typically an ongoing and interactive process, however, and the thermal design must maintain flexibility and robustness throughout the process. The thermal (or cryogenic) engineer must understand the constraints imposed by the science requirements, the specific hardware, the observing environment, the mission design, and the testing program. By balancing these often competing factors, the system-oriented thermal engineer can work together with the experiment team to produce an effective overall design of the instrument.

This study aimed to develop and assess the content validity and reliability of a cognitively adapted self-report questionnaire designed for surveillance of gingivitis in adolescents. Ten predetermined self-report questions evaluating early signs and symptoms of gingivitis were preliminary assessed by a panel of clinical experts. Eight questions were selected and cognitively tested in 20 adolescents aged 12 to 18 years from Santiago de Chile. The questionnaire was then conducted and answered by 178 Chilean adolescents. Internal consistency was measured using the Cronbach's alpha and temporal stability was calculated using the Kappa-index. A reliable final self-report questionnaire consisting of 5 questions was obtained, with a total Cronbach's alpha of 0.73 and a Kappa-index ranging from 0.41 to 0.77 between the different questions. The proposed questionnaire is reliable, with an acceptable internal consistency and a temporal stability from moderate to substantial, and it is promising for estimating the prevalence of gingivitis in adolescents.

Optimal tariff design under consumer self-selection

This report considers the design of electricity tariffs which guides an individual consumer to select the tariff designed for his consumption pattern. In the model the utility maximizes the weighted sum of individual consumers` benefits of electricity consumption subject to the utility`s revenue requirement constraints. The consumers` free choice of tariffs is ensured with the so-called self-selection constraints. The relationship between the consumers` optimal choice of tariffs and the weights in the aggregated consumers` benefit function is analyzed. If such weights exist, they will guarantee both the consumers` optimal choice of tariffs and the efficient consumption patterns. Also the welfare effects are analyzed by using demand parameters estimated from a Finnish dynamic pricing experiment. The results indicate that it is possible to design an efficient tariff menu with the welfare losses caused by the self-selection constraints being small compared with the costs created when some consumers choose tariffs other than assigned for them.

Directory of Open Access Journals (Sweden)

Giulio Sergio Roi

Full Text Available The knee is the weight-bearing joint most commonly associated with sports injuries, and therefore is most at risk of developing degenerative changes, including osteoarthritis. Skyrunners can be considered to be at risk of developing symptoms of post-traumatic osteoarthritis due to downhill running.The aim of this study was to analyze the health of the knee joints of a large group of these athletes via a specific self-report questionnaire.This study was carried out by asking the participants of seven official Skyraces (22.4±3.1 km length; 1596±393 m elevation to fill out a questionnaire. Information regarding age, sex, downhill elevation (m during training and competitions over the last month, and history of previous knee injury was also collected before the participants filled out the Knee injury and Osteoarthritis Outcome Score (KOOS, which is a reliable and validated instrument designed to assess patients' opinions about their knees and associated problems that can result in post-traumatic osteoarthritis. Athletes were divided into six age groups (from 17 to 70 years and 12 groups based on the downhill gradient they had covered over the last month (from 1,000 to 40,000 m.Six hundred twenty-one questionnaires were collected from 45% of the participants in the seven races. Multivariate analysis revealed that self-reported KOOS scores were unrelated to age, sex and monthly downhill gradient. Only 74 (12% of the participants reported previous knee injuries. Significant differences in the five subscales of the KOOS were found between skyrunners with and without previous knee injuries (P<0.01.In the studied population, regular training for downhill running and participation in Skyraces could not be considered risk factors for subjective knee symptoms. Skyrunners with self-reported histories of knee injuries scored worse on all five subscales of the KOOS.

Design and validation of a standards-based science teacher efficacy instrument

Science.gov (United States)

Kerr, Patricia Reda

National standards for K--12 science education address all aspects of science education, with their main emphasis on curriculum---both science subject matter and the process involved in doing science. Standards for science teacher education programs have been developing along a parallel plane, as is self-efficacy research involving classroom teachers. Generally, studies about efficacy have been dichotomous---basing the theoretical underpinnings on the work of either Rotter's Locus of Control theory or on Bandura's explanations of efficacy beliefs and outcome expectancy. This study brings all three threads together---K--12 science standards, teacher education standards, and efficacy beliefs---in an instrument designed to measure science teacher efficacy with items based on identified critical attributes of standards-based science teaching and learning. Based on Bandura's explanation of efficacy being task-specific and having outcome expectancy, a developmental, systematic progression from standards-based strategies and activities to tasks to critical attributes was used to craft items for a standards-based science teacher efficacy instrument. Demographic questions related to school characteristics, teacher characteristics, preservice background, science teaching experience, and post-certification professional development were included in the instrument. The instrument was completed by 102 middle level science teachers, with complete data for 87 teachers. A principal components analysis of the science teachers' responses to the instrument resulted in two components: Standards-Based Science Teacher Efficacy: Beliefs About Teaching (BAT, reliability = .92) and Standards-Based Science Teacher Efficacy: Beliefs About Student Achievement (BASA, reliability = .82). Variables that were characteristic of professional development activities, science content preparation, and school environment were identified as members of the sets of variables predicting the BAT and BASA

Opto-mechanical design for transmission optics in cryogenic space instrumentation

Kroes, Gabby; Venema, Lars; Navarro, Ramón

2017-11-01

NOVA is involved in the development and realization of various optical astronomical instruments for groundbased as well as space telescopes, with a focus on nearand mid-infrared instrumentation. NOVA has developed a suite of scientific instruments with cryogenic optics for the ESO VLT and VLTI instruments: VISIR, MIDI, the SPIFFI 2Kcamera for SINFONI, X-shooter and MATISSE. Other projects include the cryogenic optics for MIRI for the James Webb Space Telescope and several E-ELT instruments. Mounting optics is always a compromise between firmly fixing the optics and preventing stresses within the optics. The fixing should ensure mechanical stability and thus accurate positioning in various gravity orientations, temperature ranges, during launch, transport or earthquake. On the other hand, the fixings can induce deformations and sometimes birefringence in the optics and thus cause optical errors. Even cracking or breaking of the optics is a risk, especially when using brittle infrared optical materials at the cryogenic temperatures required in instruments for infrared astronomy, where differential expansion of various materials amounts easily to several millimeters per meter. Special kinematic mounts are therefore needed to ensure both accurate positioning and low stress. This paper concentrates on the opto-mechanical design of optics mountings, especially for large transmission optics in cryogenic circumstances in space instruments. It describes the development of temperature-invariant ("a-thermal") kinematic designs, their implementation in ground based instrumentation and ways to make them suitable for space instruments.

Most Alzheimer disease clinical trials that compare the use of health services rely on reports of caregivers. The goal of this study was to assess the accuracy of self-reports among older adults with Alzheimer disease and their caregiver proxy respondents. This issue is particularly relevant to Alzheimer disease clinical trials because inaccuracy can lead both to loss of power and increased bias in study outcomes. We compared respondent accuracy in reporting any use and in reporting the frequency of use with actual utilization data as documented in a comprehensive database. We next simulated the impact of underreporting and overreporting on sample size estimates and treatment effect bias for clinical trials comparing utilization between experimental groups. Respondents self-reports have a poor level of accuracy with κ-values often below 0.5. Respondents tend to underreport use even for rare events such as hospitalizations and nursing home stays. In analyses simulating underreporting and overreporting of varying magnitude, we found that errors in self-reports can increase the required sample size by 15% to 30%. In addition, bias in the reported treatment effect ranged from 3% to 18% due to both underreporting and overreporting errors. Use of self-report data in clinical trials of Alzheimer disease treatments may inflate sample size needs. Even when adequate power is achieved by increasing sample size, reporting errors can result in a biased estimate of the true effect size of the intervention.

Design Thinking for mHealth Application Co-Design to Support Heart Failure Self-Management.

Woods, Leanna; Cummings, Elizabeth; Duff, Jed; Walker, Kim

2017-01-01

Heart failure is a prevalent, progressive chronic disease costing in excess of $1billion per year in Australia alone. Disease self-management has positive implications for the patient and decreases healthcare usage. However, adherence to recommended guidelines is challenging and existing literature reports sub-optimal adherence. mHealth applications in chronic disease education have the potential to facilitate patient enablement for disease self-management. To the best of our knowledge no heart failure self-management application is available for safe use by our patients. In this paper, we present the process established to co-design a mHealth application in support of heart-failure self-management. For this development, an interdisciplinary team systematically proceeds through the phases of Stanford University's Design Thinking process; empathise, define, ideate, prototype and test with a user-centred philosophy. Using this clinician-led heart failure app research as a case study, we describe a sequence of procedures to engage with local patients, carers, software developers, eHealth experts and clinical colleagues to foster rigorously developed and locally relevant patient-facing mHealth solutions. Importantly, patients are engaged in each stage with ethnographic interviews, a series of workshops and multiple re-design iterations.

Patients' non-adherence to immunosuppressant treatment after organ transplantation may lead to organ failure, graft loss and death. Non-adherence among Swedish kidney transplant recipients has not previously been studied. Hence the aim of this study was to explore non-adherence among Swedish kidney transplant recipients by using self-report instruments as well as testing the hypothesis that there is a difference in self-reported symptoms, beliefs about medicine and social support between respondents with or without self reported non-adherence. In the present cross sectional study 250 renal transplant recipients participated by replying to a questionnaire. Two validated instruments were included, one on beliefs about medicine (the BMQ©), the other on nonadherence (the BAASIS©). Only 46 % never failed to follow the medical treatment with respect to taking the drugs, dosage or timing (>2 hrs from prescribed time). Timing was the most frequently reported deviation (48 %). Forty-seven patients (16 %) had failed taking at least one dose of the prescribed immunosuppressants during the past four weeks. Four individuals had reduced the prescribed doses. Only one reported taking a 'drug holiday'. Nine participants reported stronger concerns than necessities for immunosuppressive medication. For the BMQ the necessity scores were extremely high while the scores for concern were low. Risk behaviour identified by the BAASIS had no association in risk attitudes as identified in the BMQ. The only factor relating to non-adherence was lack of social support (p=0.022). In general adherence was high. Identification of the exceptions remains a challenge.

An instrumented capsule is being developed to be able to measure fuel characteristics, such as fuel temperature, internal pressure of fuel rod, fuel elongation, and neutron flux, etc., during the irradiation test of nuclear fuel in HANARO. The instrumented capsule for measuring and monitoring fuel centerline temperature and neutron flux was designed and manufactured. The instrumented capsule includes three test fuel rods installed thermocouple to measure fuel centerline temperature and three SPNDs (Self-Powered Neutron Detector) to monitor the neutron flux. Its stability was verified by out-of-pile performance test, and its safety evaluation was also shown that the safety requirements were satisfied. And then, to verify the design of the instrumented capsule in the test hole, it was successfully irradiated in the test hole of HANARO from March 14, 2003 to June 1, 2003 (53.8 full power days at 24 MWth). During irradiation, the centerline temperature of PWR UO{sub 2} fuel pellets fabricated by KEPCO Nuclear Fuel Company and the neutron flux were continuously measured and monitored. The test fuel rods were irradiated at less than 350 W/cm to 5.13 GWD/MTU with fuel centerline peak temperature below 1,375 .deg. C. The structural stability of the capsule was satisfied by the naked eye in service pool of HANARO. The capsule and test fuel rods were dismantled and test fuel rods were examined at the hot cell of IMEF (Irradiated Material Examination Facility)

Bullying in schools is a major health concern throughout the world, contributing to poor educational and mental health outcomes. School nurses are well placed to facilitate the implementation and evaluation of bullying prevention strategies. To evaluate the effect of such strategies, it is necessary to measure children's behavior over time. This scoping review of instruments that measure the self-report of aggressive behavior and bullying by children will inform the evaluation of bullying interventions. This review aimed to identify validated instruments that measure aggression and bullying among preadolescent children (age 8-12). The review was part of a larger study that sought to differentiate bullying from aggressive behavior by measuring the self-report of power imbalance between the aggressor and the child being bullied. The measurement of power imbalance was therefore a key aspect of the scoping review.

Healthy eating habits promote wellness and prevent disease, however, despite the intention to change a bad habit, people often fail in theirattempts. This is due, since the performance of a change requires self-regulation skills that allow to observe, to evaluate and to take an action, in a constant motivation during the all the process; not only theknowledge about proper nutrition. The objective of this study was to design and validate an instrument to evaluate the level of self-regulation for eating habits in college students.62 items were written and evaluated by four expert judges. Two applications of the instrument were performed to 487 subjects. An unweighted least squares factor analysis whit direct Oblimin rotation was performed. The items saturated in more than one factor were discarded, as well as those who had a loading factor less than 0.40 or commonality less than 0.30. It was obtained an instrument integrated by 14 items grouped into three factors, which explained the 46.9% of the variance: self-reaction, self-observation and self-evaluation. Cronbach's alpha yielded a high reliability coefficient (α = 0.874).The results show that the scale is a valid and reliable tool to measure of self-regulation of eating habits in college students. Its applications include the diagnostic of a population and the evaluation of interventions aimed to improving nutrition based on the assumption that the processes of change require sustained self-regulation skills in people protective effect against increases in both systolic and diastolic blood pressure.

The WFIRST-AFTA coronagraph instrument takes advantage of AFTAs 2.4-meter aperture to provide novel exoplanet imaging science at approximately the same instrument cost as an Explorer mission. The AFTA coronagraph also matures direct imaging technologies to high TRL for an Exo-Earth Imager in the next decade. The coronagraph Design Reference Mission (DRM) optical design is based on the highly successful High Contrast Imaging Testbed (HCIT), with modifications to accommodate the AFTA telescope design, service-ability, volume constraints, and the addition of an Integral Field Spectrograph (IFS). In order to optimally satisfy the three science objectives of planet imaging, planet spectral characterization and dust debris imaging, the coronagraph is designed to operate in two different modes: Hybrid Lyot Coronagraph or Shaped Pupil Coronagraph. Active mechanisms change pupil masks, focal plane masks, Lyot masks, and bandpass filters to shift between modes. A single optical beam train can thus operate alternatively as two different coronagraph architectures. Structural Thermal Optical Performance (STOP) analysis predicts the instrument contrast with the Low Order Wave Front Control loop closed. The STOP analysis was also used to verify that the optical/structural/thermal design provides the extreme stability required for planet characterization in the presence of thermal disturbances expected in a typical observing scenario. This paper describes the instrument design and the flow down from science requirements to high level engineering requirements.

This study aims to develop a valid and reliable chronic kidney disease self-management instrument (CKD-SM) for assessing early stage chronic kidney disease patients' self-management behaviours. Enhancing early stage chronic kidney disease patients' self-management plays a key role in delaying the progression of chronic kidney disease. Healthcare provider understanding of early stage chronic kidney disease patients' self-management behaviours can help develop effective interventions. A valid and reliable instrument for measuring chronic kidney disease patients' self-management behaviours is needed. A cross-sectional descriptive study collected data for principal components analysis with oblique rotation. Mandarin- or Taiwanese-speaking adults with chronic kidney disease (n=252) from two medical centres and one regional hospital in Southern Taiwan completed the CKD-SM. Construct validity was evaluated by exploratory factor analysis. Internal consistency and test-retest reliability were estimated by Cronbach's alpha and Pearson correlation coefficients. Four factors were extracted and labelled self-integration, problem-solving, seeking social support and adherence to recommended regimen. The four factors accounted for 60.51% of the total variance. Each factor showed acceptable internal reliability with Cronbach's alpha from 0.77-0.92. The test-retest correlations for the CKD-SM was 0.72. The psychometric quality of the CKD-SM instrument was satisfactory. Research to conduct a confirmatory factor analysis to further validate this new instrument's construct validity is recommended. The CKD-SM instrument is useful for clinicians who wish to identify the problems with self-management among chronic kidney disease patients early. Self-management assessment will be helpful to develop intervention tailored to the needs of the chronic kidney disease population. © 2013 Blackwell Publishing Ltd.

Caregivers (CGs) contribute important assistance with heart failure (HF) self-care, including daily maintenance, symptom monitoring, and management. Until CGs' contributions to self-care can be quantified, it is impossible to characterize it, account for its impact on patient outcomes, or perform meaningful cost analyses. The purpose of this study was to conduct psychometric testing and item reduction on the recently developed 34-item Caregiver Contribution to Heart Failure Self-care (CACHS) instrument using classical and item response theory methods. Fifty CGs (mean age 63 years ±12.84; 70% female) recruited from a HF clinic completed the CACHS in 2014 and results evaluated using classical test theory and item response theory. Items would be deleted for low (.95) endorsement, low (.7) corrected item-total correlations, significant pairwise correlation coefficients, floor or ceiling effects, relatively low latent trait and item information function levels ( .5), and differential item functioning. After analysis, 14 items were excluded, resulting in a 20-item instrument (self-care maintenance eight items; monitoring seven items; and management five items). Most items demonstrated moderate to high discrimination (median 2.13, minimum .77, maximum 5.05), and appropriate item difficulty (-2.7 to 1.4). Internal consistency reliability was excellent (Cronbach α = .94, average inter-item correlation = .41) with no ceiling effects. The newly developed 20-item version of the CACHS is supported by rigorous instrument development and represents a novel instrument to measure CGs' contribution to HF self-care. © 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.

Every company in Indonesia is responsible for their worker health and safety condition as mentioned in UU No I year 1970. In manufacturing industries, there are many manual tasks dealing with high work load and risk, so that they require excellent concentration and physical condition. There is no ideal way to guarantee worker safety without a real time physiological monitoring. This paper reports our ongoing study in conceptual design development of worker's clothing which is equipped with a wearable instrumentation system. The system is designed to detect and measure body temperature and pulse in real time. Some electrical components such as, LCD (liquid crystal display), LEDs (light emitting diode), batteries, and physiological sensors were assembled. All components are controlled by a wearable on board controller. LEDs is used as alert which can indicate abnormal physical conditions. The LCD was added to provide more detail information. TMP 36 and XD-58C were selected as the physiological sensors. Finally, an Arduino Lilypad was chosen for the controller. This instrumentation system was verified by accurately detected and inform physiological condition of 3 subjects. Further we are going to attach the system to a worker's clothing which was specifically designed to simplify and comfortable usage.

Xia, Jiangtao; Mao, Xiaoli; Zhao, Jing

2009-11-01

In order to autotrack the object and detect the solar UV index, a reliable real-time high-precise instrument is proposed in this paper. This instrument involves two subsystems: the autotrack and detecting modules. The autotrack module consists of four-quadrant photo detector, multi-channel signal processing circuit and precise stepping system. The detecting module designed for dada measurement and acquisition is made up of the ultraviolet sensor UV460 and high precision A/D converter MAX1162. The key component of the entire instrument is ultralow-power microprocessor MSP430 which is used for entire system controlling and data processing. The lower system of autotracking and measurement is communicated with upper PC computer by RS232 module. In the experiment, the tracking precision of two-dimensional motion revolving stage is calibrated to be less than 0.05°. Experimental results indicate that the system designed could realize the precise autotracking and detecting function well, and the measure precision of system has reached the desirable target.

Contemporary theories of social anxiety emphasize the role of cognitive processes. Although social anxiety disorder is one of the most common mental health problems in adolescents, there are very few self-report instruments available to measure cognitive processes related to social anxiety in adolescents, let alone non-English instruments. The Self-Statements during Public Speaking Scale (SSPS; Hofmann & DiBartolo, 2000) is a brief self-report measure designed to assess self-statements related to public speaking, the most commonly feared social performance situation. In order to fill this gap in the literature, we translated the SSPS into Spanish and administered it to 1,694 adolescents from a community sample, a clinical sample composed of 71 subjects with a principal diagnosis of social anxiety disorder; and a clinical control group consisting of 154 patients. The scale showed good psychometric properties, supporting the use of the Spanish version of the SSPS in adolescents.

Tinkering self-efficacy and team interaction on freshman engineering design teams

Science.gov (United States)

Richardson, Arlisa Labrie

This study utilizes Bandura's theory of self-efficacy as a framework to examine the development of tinkering skills white working on a freshman engineering design team. The four sources of self-efficacy were analyzed in the context of tinkering within the design team. The research question, 'Does tinkering self-efficacy change for female students during the Freshman Engineering Design class while working on mixed sex teams?', was addressed using quantitative data collection and field observations. Approximately 41 students enrolled in a freshman engineering design class at a public university in the southwest participated by providing self-reports about their tinkering involvement during each design project. In addition, three mixed-sex student teams were observed while working to complete the course design projects. An observation protocol based on Bandura's sources of self efficacy, was used to document tinkering interactions within the three observed teams. The results revealed that Bandura's sources of self-efficacy influenced tinkering involvement. The self-efficacy source, performance accomplishment measured through prior tinkering experience, was the most influential on tinkering involvement. Unlike Bandura's ranking of influence, verbal persuasion was shown to correlate with more tinkering behaviors than the observation of others. The number of females on a team had no impact on tinkering involvement. Tinkering involvement did not change as students progressed from one project to another. However, the competitive nature of the design project appeared to have a negative impact on tinkering involvement and the division of tasks within the team. In addition, a difference was found in the female students' perception of their tinkering involvement and observation of their tinkering involvement. The findings suggest that effective implementation of teamwork including teamwork preparation, more emphasis on the design process and the elimination of competition

Imaging of the human upper airway is widely used in medicine, in both clinical practice and research. Common imaging modalities include video endoscopy, X-ray CT, and MRI. However, no current modality is both quantitative and safe to use for extended periods of time. Such a capability would be particularly valuable for sleep research, which is inherently reliant on long observation sessions. We have developed an instrument capable of quantitative imaging of the human upper airway, based on endoscopic optical coherence tomography. There are no dose limits for optical techniques, and the minimally invasive imaging probe is safe for use in overnight studies. We report on the design of the instrument and its use in preliminary clinical studies, and we present results from a range of initial experiments. The experiments show that the instrument is capable of imaging during sleep, and that it can record dynamic changes in airway size and shape. This information is useful for research into sleep disorders, and potentially for clinical diagnosis and therapies.

Abstract The major infectious diseases in Chile encompass the periodontal diseases, with a combined prevalence that rises up to 90% of the population. Thus, the population-based surveillance of periodontal diseases plays a central role for assessing their prevalence and for planning, implementing, and evaluating preventive and control programs. Self-report questionnaires have been proposed for the surveillance of periodontal diseases in adult populations world-wide. Objective This study aimed to develop and assess the content validity and reliability of a cognitively adapted self-report questionnaire designed for surveillance of gingivitis in adolescents. Material and Methods Ten predetermined self-report questions evaluating early signs and symptoms of gingivitis were preliminary assessed by a panel of clinical experts. Eight questions were selected and cognitively tested in 20 adolescents aged 12 to 18 years from Santiago de Chile. The questionnaire was then conducted and answered by 178 Chilean adolescents. Internal consistency was measured using the Cronbach’s alpha and temporal stability was calculated using the Kappa-index. Results A reliable final self-report questionnaire consisting of 5 questions was obtained, with a total Cronbach’s alpha of 0.73 and a Kappa-index ranging from 0.41 to 0.77 between the different questions. Conclusions The proposed questionnaire is reliable, with an acceptable internal consistency and a temporal stability from moderate to substantial, and it is promising for estimating the prevalence of gingivitis in adolescents.

Introduction Self-report physical activity assessment tools are commonly used for the evaluation of physical activity levels in individuals with stroke. A great variety of these tools have been developed and widely used in recent years, which justify the need to examine their measurement properties and clinical utility. Therefore, the main objectives of this systematic review are to examine the measurement properties and clinical utility of self-report measures of physical activity and discuss the strengths and limitations of the identified tools. Methods and analysis A systematic review of studies that investigated the measurement properties and/or clinical utility of self-report physical activity assessment tools in stroke will be conducted. Electronic searches will be performed in five databases: Medical Literature Analysis and Retrieval System Online (MEDLINE) (PubMed), Excerpta Medica Database (EMBASE), Physiotherapy Evidence Database (PEDro), Literatura Latino-Americana e do Caribe em Ciências da Saúde (LILACS) and Scientific Electronic Library Online (SciELO), followed by hand searches of the reference lists of the included studies. Two independent reviewers will screen all retrieve titles, abstracts, and full texts, according to the inclusion criteria and will also extract the data. A third reviewer will be referred to solve any disagreement. A descriptive summary of the included studies will contain the design, participants, as well as the characteristics, measurement properties, and clinical utility of the self-report tools. The methodological quality of the studies will be evaluated using the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) checklist and the clinical utility of the identified tools will be assessed considering predefined criteria. This systematic review will follow the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) statement. Discussion This systematic review will

Negriff, Sonya; Schneiderman, Janet U; Trickett, Penelope K

2017-02-01

The present study used data from an ongoing longitudinal study of the effects of maltreatment on adolescent development to (1) describe rates of maltreatment experiences obtained from retrospective self-report versus case record review for adolescents with child welfare-documented maltreatment histories, (2) examine self-reported versus child welfare-identified maltreatment in relation to mental health and risk behavior outcomes by maltreatment type, and (3) examine the association between the number of different types of maltreatment and mental health and risk behavior outcomes. Maltreatment was coded from case records using the Maltreatment Case Record Abstraction Instrument (MCRAI) and participants were asked at mean age = 18.49 about childhood maltreatment experiences using the Comprehensive Trauma Interview (CTI). Results showed that an average of 48% of maltreatment found by the MCRAI for each type of maltreatment were unique cases not captured by the CTI, whereas an average of 40% self-reported maltreatment (CTI) was not indicated by the MCRAI. Analyses with outcomes showed generally, self-reported maltreatment, regardless of concordance with MCRAI, was related to the poorest outcomes. The difference in associations with the outcomes indicates both self-report and case record review data may have utility depending on the outcomes being assessed.

Directory of Open Access Journals (Sweden)

CW Chang

2014-07-01

Full Text Available Postoperative wound infection in an instrumented spine patient is often disastrous. Management includes implant removal leading to spine instability. Negative pressure wound therapy (NPWT applied to the spine surgical wound is one of the wound care technique with successful results. We report a case of a man who sustained Chance fracture of Lumbar 1 (L1 vertebra treated with long segment posterior instrumentation, who unfortunately developed Extended-spectrum beta-lactamase (ESBL positive E. coli infection one month after the operation. After careful debridement of the wound, the implant became exposed. Three cycles of NPWT were applied and the wound healed with granulation tissue completely covering the implant, and thus negating the need to remove the implant. In conclusion, the NPWT is a good alternative in postoperative wound management especially in an instrumented spine patient.

Wilder, D.G.; Rogue, F.; Beloff, W.R.; Binnall, E.; Gregory, E.C.

1982-01-01

Responding to the widespread need for the geotechnical community to discuss instrumentation for nuclear waste repositories, a meeting was held December 2 and 3, 1981, in Denver, Colorado. This report gives the group's consensus recommendations to aid in making decisions for development of instrumentation for future repository work. The main conclusions of the working group meeting were as follows: (1) monitoring of geotechnical parameters in nuclear waste repositories will be necessary to meet licensing requirements; (2) currently available instruments are underdeveloped for this monitoring; (3) research and development to provide adequate instrumentation will need to be performed under federal sponsorship by national laboratories, universities, contractors, and consultants; and (4) a NASA-type reliability program is needed to meet the quality assurance, durability, calibration, and time schedule demands of geotechnical instrumentation development. This will require significant financial commitments from the federal sector

In this study we assessed the validity of self-reported information on the use of health care, collected through this instrument, in the Belgian Health Interview Survey (BHIS, and explored the impact of selection and reporting bias on the validity of regional differences in health care use observed in the BHIS. Methods To assess reporting bias, self-reported BHIS 2008 data were linked with register-based data from the Belgian compulsory health insurance (BCHI. The latter were compared with similar estimates from a random sample of the BCHI to investigate the selection bias. Outcome indicators included the prevalence of a contact with a GP, specialist, dentist and a physiotherapist, as well as inpatient and day patient hospitalisation. The validity of the estimates and the regional differences were explored through measures of agreement and logistic regression analyses. Results Validity of self-reported health care use varies by type of health service and is more affected by reporting than by selection bias. Compared to health insurance estimates, self-reported results underestimate the percentage of people with a specialist contact in the past year (50.5 % versus 65.0 % and a day patient hospitalisation (7.8 % versus 13.9 %. Inversely, survey results overestimated the percentage of people having visited a dentist in the past year: 58.3 % versus 48.6 %. The best concordance was obtained for an inpatient hospitalisation (kappa 0.75. Survey data overestimate the higher prevalence of a contact with a specialist [OR 1.51 (95 % CI 1.33–1.72 for self-report and 1.08 (95 % CI 1.05–1.15 for register] and underestimate the lower prevalence of a contact with a GP [ORs 0.59 (95 % CI 0.51–0.70 and 0.41 (95 % CI 0.39–0.42 respectively] in

Hirt, E R; Deppe, R K; Gordon, L J

1991-12-01

The present study was an investigation of how Ss would respond when given 2 self-handicapping options, 1 behavioral (withdrawal of practice effort) and 1 self-reported (reporting high levels of stress). Ss anticipating a diagnostic test of intellectual ability were given different instructions regarding the effects of stress and practice on test performance. Ss were told that (a) stress only, (b) practice only, (c) both stress and practice, or (d) neither stress nor practice affected test scores. Ss were then given the opportunity to self-report a handicap on a stress inventory and to behaviorally self-handicap by failing to practice before the test. High self-handicapping men and women showed evidence of self-reported handicapping, but only high self-handicapping men behaviorally self-handicapped. However, when both self-handicaps were viable, both high self-handicapping men and women preferred the self-reported over the behavioral self-handicap.

The aseismatic design of electrical instruments is carried out according to IEEE Standard 344-1971 in the USA. In Japan also, the method of aseismatic design of electrical instruments has been investigated by the representatives of electric power companies and electric machine makers since 1972. In Hitachi Ltd., the statical method of confirming aseismatic property was established on the basis of the rigid design for electrical instruments. It is convenient to examine the aseismatic property of electrical equipments by classifying them into control and switch boards, electrical appliances, equipments and circuits. It is possible to use the static method treating earthquake force as static load by avoiding resonance with the electrical equipments which have the higher natural frequency than that of buildings. The purposes of the vibration test are to prove the validity of the theoretical analysis, to clarify the vibration characteristics, and to confirm the maintenance of functions and the strength of the equipments. The vibration tests of control boards, the switch boards of enclosed type, motor control centers, the racks for instrumentation, storage batteries and electrical appliances are explained. Moreover, the vibration analysis with a computer according to finite element method is described. (Kako, I.)

Nurturing a professional nursing self-concept is crucial in nursing education. To determine whether it has been achieved, a reliable and valid measurement tool is necessary. This study therefore aimed to translate the Nurses Self-Concept Instrument (NSCI), and then ascertain the content and construct validity, and test-retest and internal consistency reliability in the Chinese version of the NSCI (NSCI-C). A methodological design was conducted with 1239 nursing students of a university recruited as the sample frame and 540 randomly selected. The results showed the content validity index of 0.81 overall, alpha of 0.92 overall, and correlation coefficient of 0.87. The mean score of the NSCI-C was significantly higher in freshman than in senior (p<.01). The hypothesized four-factor model did not fit the data well. After restructuring, two factors were explored, with 69.04% explained variance. The findings suggest that the NSCI-C is reliable and valid in nursing students. Copyright © 2015 Elsevier Ltd.

The most common explosives can be uniquely identified by measuring the elemental H/N ratio with a precision better than 10%. Monte Carlo simulations were used to design two variants of a new prompt gamma neutron activation instrument that can achieve this precision. The instrument features an intense pulsed neutron generator with precise timing. Measuring the hydrogen peak from the target explosive is especially challenging because the instrument itself contains hydrogen, which is needed for neutron moderation and shielding. By iterative design optimization, the fraction of the hydrogen peak counts coming from the explosive under interrogation increased from [Formula: see text]% to [Formula: see text]% (statistical only) for the benchmark design. In the optimized design variants, the hydrogen signal from a high-explosive shell can be measured to a statistics-only precision better than 1% in less than 30 minutes for an average neutron production yield of 109 n/s.

Molecular Design and Functional Control of Novel Self-Oscillating Polymers

2010-02-01

Full Text Available If we could realize an autonomous polymer system driven under biological conditions by a tailor-made molecular design, human beings could create unprecedented biomimetic functions and materials such as heartbeats, autonomous peristaltic pumps, etc. In order to achieve this objective, we have investigated the molecular design of such a polymer system. As a result, we were the first to demonstrate a self-oscillating polymer system driven in a solution where only malonic acid existed, which could convert the chemical energy of the Belousov-Zhabotinsky (BZ reaction into a change in the conformation of the polymer chain. To cause the self-oscillation in solution, we have attempted to construct a built-in system where the required BZ system substrates other than the organic acid are incorporated into the polymer itself. That is, the novel polymer chain incorporated the metal catalyst of the BZ reaction, a pH-control site and an oxidant supply site at the same time. As a result of introducing the pH control and oxidant supply sites into the conventional-type self-oscillating polymer chain, the novel polymer chain caused aggregation-disaggregation self-oscillations in the solution. We clarified that the period of the self-oscillation of the novel self-oscillating polymer chain was proportional to the concentration of the malonic acid. Therefore, the concentration of the malonic acid can be determined by measuring the period of the novel self-oscillating polymer solution. In this review, we introduce the detailed molecular design of the novel self-oscillating polymer chain and its self-oscillating behavior. Moreover, we report an autonomous self-oscillating polymer gel actuator that causes a bending-stretching motion under the constant conditions.

Financial management skills-that is, the skills needed to handle personal finances such as banking and paying bills-are essential to a person's autonomy, independence, and community living. To date, no comprehensive review of financial management skills instruments exists, making it difficult for clinicians and researchers to choose relevant instruments. The objectives of this review are to: (a) identify all available instruments containing financial management skill items that have been used with adults with acquired cognitive impairments; (b) categorize the instruments by source (i.e., observation based, self-report, proxy report); and (c) describe observation-based performance instruments by populations, overarching concepts measured, and comprehensiveness of financial management items. Objective (c) focuses on observation-based performance instruments as these measures can aid in situations where the person with cognitive impairment has poor self-awareness or where the proxy has poor knowledge of the person's current abilities. Two reviewers completed two systematic searches of five databases. Instruments were categorized by reviewing published literature, copies of the instruments, and/or communication with instrument authors. Comprehensiveness of items was based on nine key domains of financial management skills developed by the authors. A total of 88 discrete instruments were identified. Of these, 44 were categorized as observation-based performance and 44 as self- and/or proxy-reports. Of the 44 observation-based performance instruments, 8 had been developed for acquired brain injury populations and 24 for aging and dementia populations. Only 7 of the observation-based performance instruments had items spanning 6 or more of the 9 financial management skills domains. The majority of instruments were developed for aging and dementia populations, and few were comprehensive. This review provides foundation for future instrument psychometric and clinimetric

High integration of multi-functional instruments raises a critical issue in temperature control that is challenging due to its spatial-temporal complexity. This paper presents a multi-input multi-output (MIMO) self-tuning temperature sensing and control system for efficiently modulating the temperature environment within a multi-module instrument. The smart system ensures that the internal temperature of the instrument converges to a target without the need of a system model, thus making the control robust. The system consists of a fully-connected proportional-integral-derivative (PID) neural network (FCPIDNN) and an on-line self-tuning module. The experimental results show that the presented system can effectively control the internal temperature under various mission scenarios, in particular, it is able to self-reconfigure upon actuator failure. The system provides a new scheme for a complex and time-variant MIMO control system which can be widely applied for the distributed measurement and control of the environment in instruments, integration electronics, and house constructions.

The Large Ultraviolet/Optical/Infrared Surveyor (LUVOIR) is one of four large mission concepts currently undergoing community study for consideration by the 2020 Astronomy and Astrophysics Decadal Survey. LUVOIR is being designed to pursue an ambitious program of exoplanetary discovery and characterization, cosmic origins astrophysics, and planetary science. The LUVOIR study team is investigating two large telescope apertures (9- and 15-meter primary mirror diameters) and a host of science instruments to carry out the primary mission goals. Many of the exoplanet, cosmic origins, and planetary science goals of LUVOIR require high-throughput, imaging spectroscopy at ultraviolet (100 - 400 nm) wavelengths. The LUVOIR Ultraviolet Multi-Object Spectrograph, LUMOS, is being designed to support all of the UV science requirements of LUVOIR, from exoplanet host star characterization to tomography of circumgalactic halos to water plumes on outer solar system satellites. LUMOS offers point source and multi-object spectroscopy across the UV bandpass, with multiple resolution modes to support different science goals. The instrument will provide low (R = 8,000 - 18,000) and medium (R = 30,000 - 65,000) resolution modes across the far-ultraviolet (FUV: 100 - 200 nm) and nearultraviolet (NUV: 200 - 400 nm) windows, and a very low resolution mode (R = 500) for spectroscopic investigations of extremely faint objects in the FUV. Imaging spectroscopy will be accomplished over a 3 × 1.6 arcminute field-of-view by employing holographically-ruled diffraction gratings to control optical aberrations, microshutter arrays (MSA) built on the heritage of the Near Infrared Spectrograph (NIRSpec) on the James Webb Space Telescope (JWST), advanced optical coatings for high-throughput in the FUV, and next generation large-format photon-counting detectors. The spectroscopic capabilities of LUMOS are augmented by an FUV imaging channel (100 - 200nm, 13 milliarcsecond angular resolution, 2 × 2

The association between psychosocial work environment and employee wellbeing has repeatedly been shown. However, as environmental evaluations have typically been self-reported, the observed associations may be attributable to reporting bias. Applying instrumental-variable regression, we used staffing level (the ratio of staff to residents) as an unconfounded instrument for self-reported job demands and job strain to predict various indicators of wellbeing (perceived stress, psychological distress and sleeping problems) among 1525 registered nurses, practical nurses and nursing assistants working in elderly care wards. In ordinary regression, higher self-reported job demands and job strain were associated with increased risk of perceived stress, psychological distress and sleeping problems. The effect estimates for the associations of these psychosocial factors with perceived stress and psychological distress were greater, but less precisely estimated, in an instrumental-variables analysis which took into account only the variation in self-reported job demands and job strain that was explained by staffing level. No association between psychosocial factors and sleeping problems was observed with the instrumental-variable analysis. These results support a causal interpretation of high self-reported job demands and job strain being risk factors for employee wellbeing. © The Author 2014.

2017-09-01

Climate change and environmental conditions are high on the political agenda of international governments. Laws and regulations are being setup all around the world to improve the air quality and to reduce the impact. The growth of a number of trace gasses, including CO2, Methane and NOx are especially interesting due to their environmental impact. The regulations made are being based on both models and measurements of the trend of those trace gases over the years. Now the regulations are in place also enforcement and therewith measurements become more and more important. Instruments enabling high spectral and spatial resolution as well as high accurate measurements of trace gases are required to deliver the necessary inputs. Nowadays those measurements are usually performed by space based spectrometers. The requirement for high spectral resolution and measurement accuracy significantly increases the size of the instruments. As a result the instrument and satellite becomes very expensive to develop and to launch. Specialized instruments with a small volume and the required performance will offer significant advantages in both cost and performance. Huib's Innovative Gas Sensor (HIGS, named after its inventor Huib Visser), currently being developed at TNO is an instrument that achieves exactly that. Designed to measure only a single gas concentration, opposed to deriving it from a spectrum, it achieves high performance within a small design volume. The instrument enables instantaneous imaging of the gas distribution of the selected gas. An instrument demonstrator has been developed for NO2 detection. Laboratory measurements proved the measurement technique to be successful. An on-sky measurement campaign is in preparation. This paper addresses both the instrument design as well as the demonstrated performances.

Fellman, Ronald D.; Kaneshiro, Ronald T.; Konstantinides, Konstantinos

1990-03-01

The authors present the design and evaluation of an architecture for a monolithic, programmable, floating-point digital signal processor (DSP) for instrumentation applications. An investigation of the most commonly used algorithms in instrumentation led to a design that satisfies the requirements for high computational and I/O (input/output) throughput. In the arithmetic unit, a 16- x 16-bit multiplier and a 32-bit accumulator provide the capability for single-cycle multiply/accumulate operations, and three format adjusters automatically adjust the data format for increased accuracy and dynamic range. An on-chip I/O unit is capable of handling data block transfers through a direct memory access port and real-time data streams through a pair of parallel I/O ports. I/O operations and program execution are performed in parallel. In addition, the processor includes two data memories with independent addressing units, a microsequencer with instruction RAM, and multiplexers for internal data redirection. The authors also present the structure and implementation of a design environment suitable for the algorithmic, behavioral, and timing simulation of a complete DSP system. Various benchmarking results are reported.

To develop a new patient-reported outcome instrument (PRO) to measure body-related satisfaction quality of life (QoL). Standard 3-phase PRO design was followed; in the first phase, a qualitative design was used in 45 patients to develop a conceptual framework and to create preliminary scale domains and items. In phase 2, large-scale population testing on 1340 subjects was performed to reduce items and domains. In phase 3, final testing of the developed instrument on 34 patients was performed. Statistics used include Factor, RASCH, and multivariate regression analysis. Psychometric properties measured were internal reliability, item-rest, item-test, and test-retest correlations. The PRO-developed instrument is composed of four domains (satisfaction with the abdomen, sex life, self-esteem and social life, and physical symptoms) and 20 items in total. The score can range from 20 (worst) to 100 (best). Responsiveness was 100 %, internal reliability 93.3 %, and test-retest concordance 97.7 %. Body image-related QoL was superior in men than women (p instrument (p measured reliably with the Body-QoL instrument. It can be used to quantify the improvement in cosmetic and post-bariatric patients including non- or minimally invasive procedures, suction assisted lipectomy, abdominoplasty, lipoabdominoplasty, and lower body lift and to give an evidence-based approach to standard practice.

2009-01-01

In this study, first, different mix design of four types of Self-Compacting Concrete, 1. Self-Compacting Concrete consisted of only nano silica, 2. Self-Compacting Concrete included only micro silica, 3. Self-Compacting Concrete consisted of both micro silica and nano silica and 4. Self-Compacting Concrete without micro silica and nano silica called as control mix, were casted and tested to find out the values of the Slump Flow, L-Box and 7 and 28 days compressive strength. Then, based on the results obtained and as yet there is no universally accepted standard for characterizing of Self-Compacting Concrete, the most suitable four concrete mixes were selected for further investigation of fresh and hardened concrete. For selected mixes, the fresh concrete properties such as values of the Slump Flow, L-Box, V-Funnel, J-Ring and hardened engineering properties such as compressive and flexural strength, shrinkage and swelling values were investigated for three curing conditions at short and long term. The results showed that the engineering properties of Self-Compacting Concrete mixes could not be improved by adding only nano silica. However, a satisfactory behavior can be achieved using micro silica in the Self-Compacting Concrete mixes. However, by adding both micro silica and nano silica to the Self-Compacting Concrete mixtures, the best effect on the engineering properties was reported while comparing to the control mixes.

The purpose of this study was to evaluate measurement properties of self-report questionnaires for studies published in Korean nursing journals. Of 424 Korean nursing articles initially identified, 168 articles met the inclusion criteria. The methodological quality of the measurements used in the studies and interpretability were assessed using the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) checklist. It consists of items on internal consistency, reliability, measurement error, content validity, construct validity including structural validity, hypothesis testing, cross-cultural validity, and criterion validity, and responsiveness. For each item of the COSMIN checklist, measurement properties are rated on a four-point scale: excellent, good, fair, and poor. Each measurement property is scored with worst score counts. All articles used the classical test theory for measurement properties. Internal consistency (72.6%), construct validity (56.5%), and content validity (38.2%) were most frequently reported properties being rated as 'excellent' by COSMIN checklist, whereas other measurement properties were rarely reported. A systematic review of measurement properties including interpretability of most instruments warrants further research and nursing-focused checklists assessing measurement properties should be developed to facilitate intervention outcomes across Korean studies.

Full Text Available Małgorzata Farnik, Władysław PierzchałaDepartment of Pneumonology, Silesian University of Medicine, Katowice, PolandAbstract: Patient-related outcomes measures could provide important information for the current state of the art in medical care and even have an impact on macrodecisions in the health care system. Patient-related outcomes were initially defined as subjective health indicators that allow disability and illness to be assessed, based on patient, caregiver, or physician self-reports. As illness involves psychological and behavioral complex processes of care, a multidisciplinary approach in measuring patient-reported outcomes should be recommended, such as quality of life questionnaires. Patient-related outcomes measures should correspond to specific clinical situations and bring opportunities to improve quality of care. Objective measurements enable quantitative data to be collected and analyzed. Depending on the aim of the research, investigators can use existing methods or develop new tools. This publication presents a methodology for developing patient-related outcomes measures, based on a multistage procedure. The proper definition of specific study objectives and the methodology of instrument development are crucial for successfully transferring the study concept. The model of instrument development is the process of starting from the preliminary phase and includes questionnaire design and scaling, pilot testing (cognitive debriefing, revision of the preliminary version, evaluation of the new tool, and implementation. Validation of the new instrument includes reliability, reproducibility, internal consistency, and responsiveness. The process of designing the new tool should involve a panel of experts, including clinicians, psychologists (preliminary phase, and statisticians (scale development and scoring, and patients (cognitive debriefing.

Designing Successful Next-Generation Instruments to Detect the Epoch of Reionization

Thyagarajan, Nithyanandan; Hydrogen Epoch of Reionization Array (HERA) team, Murchison Widefield Array (MWA) team

2018-01-01

The Epoch of Reionization (EoR) signifies a period of intense evolution of the Inter-Galactic Medium (IGM) in the early Universe caused by the first generations of stars and galaxies, wherein they turned the neutral IGM to be completely ionized by redshift ≥ 6. This important epoch is poorly explored to date. Measurement of redshifted 21 cm line from neutral Hydrogen during the EoR is promising to provide the most direct constraints of this epoch. Ongoing experiments to detect redshifted 21 cm power spectrum during reionization, including the Murchison Widefield Array (MWA), Precision Array for Probing the Epoch of Reionization (PAPER), and the Low Frequency Array (LOFAR), appear to be severely affected by bright foregrounds and unaccounted instrumental systematics. For example, the spectral structure introduced by wide-field effects, aperture shapes and angular power patterns of the antennas, electrical and geometrical reflections in the antennas and electrical paths, and antenna position errors can be major limiting factors. These mimic the 21 cm signal and severely degrade the instrument performance. It is imperative for the next-generation of experiments to eliminate these systematics at their source via robust instrument design. I will discuss a generic framework to set cosmologically motivated antenna performance specifications and design strategies using the Precision Radio Interferometry Simulator (PRISim) -- a high-precision tool that I have developed for simulations of foregrounds and the instrument transfer function intended primarily for 21 cm EoR studies, but also broadly applicable to interferometer-based intensity mapping experiments. The Hydrogen Epoch of Reionization Array (HERA), designed in-part based on this framework, is expected to detect the 21 cm signal with high significance. I will present this framework and the simulations, and their potential for designing upcoming radio instruments such as HERA and the Square Kilometre Array (SKA).

Physical activity (PA) promotion among youth is a public health priority and there is a need for robust surveillance systems to help support such initiatives. Existing youth PA self-report instruments that are used for surveillance lack information regarding the types and contexts of activity. Further, these instruments have limited validity with accelerometry. The purpose of the present study was to develop a self-report instrument, with sound psychometric properties, for monitoring compliance with PA guidelines in youth. In focus groups, 162 middle school students identified 30 forms of PA that are highly prevalent in that age group. We incorporated these activities into three preliminary forms of a self-report instrument. An independent sample of middle school students (n = 537) was randomly assigned to complete one of the three preliminary versions of the instrument. Rasch analysis was applied to the responses to the three formats, and a yes/no plus frequency format emerged as the preferred method. A third sample of 342 middle school students then completed the yes/no plus frequency instrument twice following a seven-day period during which they wore an accelerometer. Using both Rasch analysis and traditional correlational methods, validity and reliability of a 14-item instrument were established. Data were collected during 2012 - 2015. Spearman correlation coefficient for the association between the cumulative score for the 14 items and minutes per day of accelerometry-derived moderate-to-vigorous physical activity (MVPA) was 0.33 (95% CI 0.22, 0.43; pCommercial-No Derivatives License 4.0 (CCBY-NC-ND), where it is permissible to download and share the work provided it is properly cited.

The present study was developed to comprehensively investigate the occupational health problems among teachers of primary and secondary schools in Hong Kong. A random sample of 1,710 respondents was generated from the database of Hong Kong Professional Teachers' Union (HKPTU) members. A self-administrated questionnaire was designed and sent by mail to the teachers of primary and secondary schools in HK. The results indicated that comparing with one year and five years ago, 91.6% and 97.3% of the responding teachers reported an increase of perceived stress level, respectively. Heavy workload and time pressure, education reforms, external school review, pursuing further education, and managing students' behaviour and learning were the most frequently reported sources of work stress. The four most frequently reported stress management activities were sleeping, talking to neighbors and friends, self-relaxing, and watching television, while the least frequently reported activity was doing more exercises or sports.

Stair climbing is an activity of daily living that might contribute to increase levels of physical activity (PA). To date, there is no study examining the validity of climbing stairs assessed by self-report. The aim of this study was, therefore, to examine the validity of estimated stair climbing from one question included in a common questionnaire compared to a pattern-recognition activity monitor in older adults. A total of 138 older adults (94 women), aged 65-86 years (70.9 ± 4.7 years), from the IMPACT65 + study participated in this validity study. Estimates of stair climbing were obtained from the European Prospective Investigation into Cancer and Nutrition (EPIC) PA questionnaire. An objective assessment of stair climbing was obtained with the Intelligent Device for Energy Expenditure and Activity (IDEEA) monitor. The correlation between both methods to assess stair climbing was fair (ρ = 0.22, p = 0.008 for PA energy expenditure and ρ = 0.26, p = 0.002 for duration). Mean differences between self-report and the IDEEA were 7.96 ± 10.52 vs. 9.88 ± 3.32 METs-min/day for PA energy expenditure, and 0.99 ± 1.32 vs. 1.79 ± 2.02 min/day for duration (both Wilcoxon test p < 0.001). Results from the Bland-Altman analysis indicate that bias between both instruments were -1.91 ± 10.30 METs-min/day and -0.80 ± 1.99 min/day, and corresponding limits of agreement for the two instruments were from 18.27 to -22.10 METs-min/day and from 3.09 to -4.70 min/day, respectively. Our results indicate that self-reported stair climbing has modest validity to accurately rank old age participants, and underestimates both PAEE and its duration, as compared with an objectively measured method.

of collective intelligence, derived from the real lives of players to be redeployed in their real urban futures. Vitally, city gaming enables the negotiation of this future, as players with conflicting interests are given an opportunity to develop compatible, even shared, visions. By transforming serious issues into a playful and engaging (although no less serious experience, city gaming unlocks difficult conversations and helps to build communities in the long term. The urban design, policy and action plans generated collaboratively through gaming will increase social coherence and local agency, as well as cutting costs and time in urban development processes. This thesis proposes Generative City Gaming as an innovative urban planning and design method built on the tradition of serious gaming. Going beyond the educational scope of other serious games, the ultimate aim of city gaming is to become operational in urban processes – a goal in the process of making a reality since 2008, when Generative City Gaming was first applied to a real urban questions in the Netherlands, later expanding to Istanbul, Tirana, Brussels, and Cape Town. “Negotiation and Design for the Self-Organizing City” reports on six of the twelve city games played to date which were instrumental in the evolution of the method: Play Almere Haven tested whether a game based on self-organizing mechanisms could provide an urban order; Play Rotterdam questioned whether game-derived design could be implemented in urban renewal of a central Rotterdam neighborhood; Yap-Yaşa was played with real urban stakeholders for transforming Istanbul’s self-built neighbourhoods; Play Noord investigated a masterplan on hold could be fixed by unconventional stakeholders; Play Oosterwold jumped up a scale to test the rules of a flexible urban expansion plan for 4500 hectares; Play Van Gendthallen, was the first to enable stakeholders to make the leap from design to reality within the game process.

The aim of the study was to clarify the developmental risk associated with hyperactive behaviour in girls in a longitudinal epidemiological design. This was investigated in a follow-up study of girls who were identified by parent and teacher ratings in a large community survey of 6- and 7-year-olds as showing pervasive hyperactivity or conduct problems or the comorbid mixture of both problems or neither problem. They were later investigated, at the age of 14 to 16 years, with a detailed self-report interview technique. Hyperactivity was a risk factor for later development, even allowing for the coexistence of conduct problems. Hyperactivity predicted academic problems and interpersonal relationship problems. Relationships with parents, by contrast, were not portrayed to be as problematic as relationships with peers and the opposite sex. Their psychological, social and occupational functioning was objectively rated to be more deviant and their self-report showed them to be more ambivalent about their future. There was a trend for hyperactivity to be self-reported as a risk for the development of continuing symptomatology but neither hyperactivity nor conduct problems were self-reported to be a risk for antisocial behaviour, substance misuse or low self-esteem in adolescence. However, they were at risk for the development of state anxiety. The results suggested girls' pattern of functioning may differ from that of boys because girls self-report a more pervasive range of social dysfunction than that previously reported in boys.

diagnoses. These 664 items were iteratively submitted to 3 rounds of cognitive interviewing with 50 community mental health center participants; the expert panel reviewed session summaries and agreed on a final set of 661 clear and concise self-report items representing the desired criteria in the DSM-5. The SAGE-SR constructed from this item pool took an average of 14 min to complete in a nonclinical sample versus 24 min in a clinical sample. Responses to individual items can be combined to generate DSM criteria endorsements and differential diagnoses, as well as provide indices of individual symptom severity. Preliminary measures of test-retest reliability in a small, nonclinical sample were promising, with good to excellent reliability for screener items in 11 of 13 diagnostic screening modules (intraclass correlation coefficient [ICC] or kappa coefficients ranging from .60 to .90), with mania achieving fair test-retest reliability (ICC=.50) and other substance use endorsed too infrequently for analysis. The SAGE-SR is a computerized adaptive self-report instrument designed to provide rigorous differential diagnostic information to clinicians. ©Benjamin Brodey, Susan E Purcell, Karen Rhea, Philip Maier, Michael First, Lisa Zweede, Manuela Sinisterra, M Brad Nunn, Marie-Paule Austin, Inger S Brodey.

Full Text Available The problems in state/region owned goods in Indonesian state and local governments are suspected to occur because of weak monitoring programs, according to many studies. A tool or instrument in implementing this monitoring program is expected to address this problem. Such tool currently doesn’t exist yet. This research aims to fill that gap by developing a monitoring instrument design for state/region owned goods by using Daerah Istimewa Yogyakarta (DIY Local Government as a research context in order to take valuable inputs for the design. This research is using developmental research method. Government Regulation were used for normative reference and Friedman’s results-based accountability quadrat were used in developing good indicators for the instrument. This research is succeeded in formulating the indicators that made up the instrument. Indicators compiled are divided into compliance-based indicators and results-based indicators. Indicators are formulated based on the validation and inputs from employees of DIY’s Assets Management Agency and experts from academia. This instrument still has some limitations that need improvement through further research.

The workshop Choosing or Developing Instruments held at the Outcome Measures in Rheumatology (OMERACT) 10 meeting was designed to help participants think about the underlying methods of instrument development. Conference pre-reading material and 3 brief introductory presentations elaborated the issues, and participants broke into discussion groups before reconvening to share insights, engage in a more general discussion of the issues, and vote on recommendations. Tradeoffs between using current imperfect measures and the long and complex process of developing new instruments were considered, together with the need for rigor in patient-reported outcome (PRO) instrument development. The main considerations for PRO instrument development were listed and a research agenda for action produced. As part of the agenda for action, it is recommended that researchers and patient partners work together to tackle these issues, and that OMERACT bring forward proposals for acceptable instrument development protocols that would meet an enhanced "Truth" statement in the OMERACT Filter.

The aim of this study was to assess the relationship between levels of anxiety symptoms and prevalence of self-report of awake and sleep bruxism in patients with temporomandibular disorders (TMD). One hundred and eighty-one female patients, aged 19-77 years, were consecutively evaluated. The patients were selected from among those who sought treatment at the TMD and Orofacial Pain Outpatient Clinic of the Petrópolis School of Medicine. All patients completed the questionnaire and underwent clinical examination, both components of the RDC/TMD, in addition to answering questions pertaining to the assessment of levels of anxiety symptoms, taken from the Symptom Check List 90 self-report instrument. The subjects were classified according to the presence of self-reported only awake bruxism, only sleep bruxism, both, or none. A logistic regression procedure was performed to evaluate the possible association through odds ratio between anxiety symptoms and self-reported awake or sleep bruxism. The cofactors for each outcome were age, self-reported bruxism during the circadian period other than the one being evaluated, and the use of selective serotonin reuptake inhibitors. It was possible to demonstrate the presence of a positive and statistically significant relationship between anxiety levels and self-reported awake bruxism. This finding was not observed in those subjects who reported sleep bruxism. A positive relationship was found between self-reported awake bruxism and levels of anxiety symptoms, but not between sleep bruxism and anxiety.

The remaining variation could be attributed to individuals' nonfamilial environments. CONCLUSION: We found that genetic factors play an important role in self......-reported reduced hearing in both men and women age 70 and older. Because self-reports of reduced hearing involve misclassification, this estimate of the genetic influence on hearing disabilities is probably conservative.

Self-report physical activity assessment tools are commonly used for the evaluation of physical activity levels in individuals with stroke. A great variety of these tools have been developed and widely used in recent years, which justify the need to examine their measurement properties and clinical utility. Therefore, the main objectives of this systematic review are to examine the measurement properties and clinical utility of self-report measures of physical activity and discuss the strengths and limitations of the identified tools. A systematic review of studies that investigated the measurement properties and/or clinical utility of self-report physical activity assessment tools in stroke will be conducted. Electronic searches will be performed in five databases: Medical Literature Analysis and Retrieval System Online (MEDLINE) (PubMed), Excerpta Medica Database (EMBASE), Physiotherapy Evidence Database (PEDro), Literatura Latino-Americana e do Caribe em Ciências da Saúde (LILACS) and Scientific Electronic Library Online (SciELO), followed by hand searches of the reference lists of the included studies. Two independent reviewers will screen all retrieve titles, abstracts, and full texts, according to the inclusion criteria and will also extract the data. A third reviewer will be referred to solve any disagreement. A descriptive summary of the included studies will contain the design, participants, as well as the characteristics, measurement properties, and clinical utility of the self-report tools. The methodological quality of the studies will be evaluated using the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) checklist and the clinical utility of the identified tools will be assessed considering predefined criteria. This systematic review will follow the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) statement. This systematic review will provide an extensive review of the measurement

Research increasingly suggests that subjective cognitive decline (SCD) in older adults, in the absence of objective cognitive dysfunction or depression, may be a harbinger of non-normative cognitive decline and eventual progression to dementia. Little is known, however, about the key features of self-report measures currently used to assess SCD. The Subjective Cognitive Decline Initiative (SCD-I) Working Group is an international consortium established to develop a conceptual framework and research criteria for SCD (Jessen et al., 2014, Alzheimers Dement 10, 844–852). In the current study we systematically compared cognitive self-report items used by 19 SCD-I Working Group studies, representing 8 countries and 5 languages. We identified 34 self-report measures comprising 640 cognitive self-report items. There was little overlap among measures—approximately 75% of measures were used by only one study. Wide variation existed in response options and item content. Items pertaining to the memory domain predominated, accounting for about 60% of items surveyed, followed by executive function and attention, with 16% and 11% of the items, respectively. Items relating to memory for the names of people and the placement of common objects were represented on the greatest percentage of measures (56% each). Working group members reported that instrument selection decisions were often based on practical considerations beyond the study of SCD specifically, such as availability and brevity of measures. Results document the heterogeneity of approaches across studies to the emerging construct of SCD. We offer preliminary recommendations for instrument selection and future research directions including identifying items and measure formats associated with important clinical outcomes.

Type 2 diabetes is a prevalent, chronic disease, which places significant burden on societies and individuals. This article reports the participatory research design of an exploratory study that introduces mobile tablet devices in the self-management of type 2 diabetes in a primary healthcare setting. Strategies from democratic dialogic theory were used in the design of the research to steer the participatory engagement between researchers and healthcare practitioners. The outcome of this phase of the research was the issue of six ‘invitations’ to 28 people with diabetes to frame their use of a mobile tablet device in managing their health. Those invitations were clustered in two themes, Empowered and Compelled, representing typical patient attitudes and behaviours. The work reported here sets the stage for a longitudinal and socially complex study that encompasses a new and comprehensive General Practitioner (GP) Super Clinic with an array of health and administrative staff, patients with a chronic health condition requiring continual self-management, a wide continuum of digital literacy capability in all participants and an ever-increasing digital society. It reports a novel research design methodology that merges democratic dialogic theory and participatory design, resulting in a grounded and agreed approach to a mobile health intervention.

This study examined relationships between self-perceived sleep quality and resilience among 116 dance students (Mean age = 21.6 years; SD = 4.348). who self-reported sleep quality with the Pittsburgh Sleep Quality Index (PSQI) and personal resilience with the Resilience Scale (RS). Most participants (59.5%) reported poor sleep quality on the PSQI, with 62.9% of the women and 42.1% of the men ( p = .092) scoring higher than five points on this instrument. On the RS, a large majority of the participants (75%) obtained scores less than 147, indicating low resilience, with no significant gender differences observed. Those reporting poor sleep quality (PSQI scores > 5) obtained lower resilience scores (RS resilience (Odds Ratio = 3.273) relative to those with good sleep quality ( p = .006). Those with shorter duration sleep (claiming they slept resilience (Odds Ratio = 3.266), relative to those with longer duration sleep (>7 hours/night). These findings can help students and dance professionals improve their performance and face pressures inherent in dance practice. Follow-up research should verify these findings in varied populations with objective sleep measures and observational data from multiple respondents.

RNA nanotechnology uses RNA structural motifs to build nanosized architectures that assemble through selective base-pair interactions. Herein, we report the crystal-structure-guided design of highly stable RNA nanotriangles that self-assemble cooperatively from short oligonucleotides. The crystal structure of an 81 nucleotide nanotriangle determined at 2.6 Å resolution reveals the so-far smallest circularly closed nanoobject made entirely of double-stranded RNA. The assembly of the nanotriangle architecture involved RNA corner motifs that were derived from ligand-responsive RNA switches, which offer the opportunity to control self-assembly and dissociation. © 2016 WILEY-VCH Verlag GmbH & Co.

The NASA Goddard Planetary Science Winter School (PSWS) is a Goddard Space Flight Center-sponsored training program, managed by Goddard's Solar System Exploration Division (SSED), for Goddard-based postdoctoral fellows and early career planetary scientists. Currently in its third year, the PSWS is an experiential training program for scientists interested in participating on future planetary science instrument teams. Inspired by the NASA Planetary Science Summer School, Goddard's PSWS is unique in that participants learn the flight instrument lifecycle by designing a planetary flight instrument under actual consideration by Goddard for proposal and development. They work alongside the instrument Principal Investigator (PI) and engineers in Goddard's Instrument Design Laboratory (IDL; idc.nasa.gov), to develop a science traceability matrix and design the instrument, culminating in a conceptual design and presentation to the PI, the IDL team and Goddard management. By shadowing and working alongside IDL discipline engineers, participants experience firsthand the science and cost constraints, trade-offs, and teamwork that are required for optimal instrument design. Each PSWS is collaboratively designed with representatives from SSED, IDL, and the instrument PI, to ensure value added for all stakeholders. The pilot PSWS was held in early 2015, with a second implementation in early 2016. Feedback from past participants was used to design the 2017 PSWS, which is underway as of the writing of this abstract.

Emotional skills and competence questionnaire (ESCQ as a self-report measure of emotional intelligence

Full Text Available Studies of emotional intelligence (EI initially appeared in academic journals in the early 1990s. The majority of studies on emotional intelligence have relied on self-ratings. In spite of the critics of self-report scales, there are a large number of self-report measures of EI present in recent literature. The main aim of this paper is to present the constructing procedure, together with the basic psychometric properties of Emotional Skills and Competence Questionnaire (ESCQ as a self-report measure of EI. Originally, this measure was developed in Croatian settings, using the theoretical framework from the Mayer-Salovey emotional intelligence model. The ESCQ instrument has been translated into several languages. The results have showed that ESCQ has three subscales with decent reliability. They share some amount of common variance with similar well-established constructs such as alexithymia, social skills, and personality traits, but they are not correlated with cognitive abilities. However, due to its sufficient reliability, a great deal of unique variance remains. This unique variance of the ESCQ scales has an incremental contribution in explaining life satisfaction and empathy (as the crucial criteria for EI, and has significant relations with relevant real-life criteria such as quality of leadership, health risk behaviors, and school achievement.

As expected, across the entire age range there was no correlation between age and digit span memory (r = .03), a strong negative correlation between age and fluid intelligence (r = -.78), and a modest positive correlation between age and crystallized intelligence (r = .27). In addition, older adults reported more physical (r = .36) and mental (r = .32) health problems than did younger adults. Of special interest was the finding that both self-reported physical and mental health accounted for significant variance in intelligence performance, particularly in older adults. Moreover, self-reported health accounted for a considerable portion of observed variance, even when age differences in self-reported health were statistically controlled.

Influence of instrument design on neutron lifetime measurements

International Nuclear Information System (INIS)

Youmans, A.H.; Hopkinson, E.C.

1975-01-01

Commercially available logging services provide a measurement of the lifetime of thermal neutrons in formations adjacent to a borehole. This lifetime provides a measure of the macroscopic thermal neutron-capture cross-section Σ of the formation, which in turn is functionally related to the abundance and constituency of the rock matrix and contained fluids. Because the measurement is extremely sensitive to an abundance of trace elements like boron and gadolinium, it is very difficult to find rock formations with an accurately known value of Σ, which is required for the accuracy of the measuring system to be experimentally tested. Various theoretical studies published suggest that errors in the determination of Σ may occur because of the influence of borehole parameters and the effects of neutron diffusion. Experimental results are reported that demonstrate that the design of the instrument is crucial to the validity of any theoretical treatment of the subject. The influence of neutron diffusion and borehole effects can be overcome by optimal selection of spacing and shielding parameters

Full Text Available Context: Nigerian glaucoma patients have an aversion to surgery and often rely on medical therapy to prevent disease progression. For medical therapy to be effective, the drugs have to be used as prescribed. Compliance has been reported to be low in the previous Nigerian studies. Aims: To evaluate the adherence rates of primary open angle glaucoma (POAG patients on medical therapy using patient self-report. Settings and Design: A hospital-based cross-sectional design was used to assess consecutive POAG patients attending a glaucoma clinic in a Tertiary Hospital in Lagos, Nigeria. Subjects and Methods: Self-reported adherence was evaluated by trained interviewers. Comprehensive clinical assessment including intraocular pressure, gonioscopy, visual field assessment, and dilated binocular funduscopy using the slit lamp and + 78D fundus lens was done. Statistical Analysis Used: Data analysis was done using MedCalc Statistical Software. Results: One hundred and fourteen patients reported adherence rates ranging from 10% to 100% with a mean adherence rate of 82.33% ± 19.25%. Only 31 respondents (27.2% reported 100% adherence. Duration of the disease was the only significant factor on multiple regression analysis. Conclusions: The development of strategies to improve compliance and persistence in glaucoma patients is crucial for the reduction of disease progression and blindness.

Design and installation of advanced computer safety related instrumentation

Koch, S.; Andolina, K.; Ruether, J.

1993-01-01

The rapidly developing area of computer systems creates new opportunities for commercial utilities operating nuclear reactors to improve plant operation and efficiency. Two of the main obstacles to utilizing the new technology in safety-related applications is the current policy of the licensing agencies and the fear of decision making managers to introduce new technologies. Once these obstacles are overcome, advanced diagnostic systems, CRT-based displays, and advanced communication channels can improve plant operation considerably. The article discusses outstanding issues in the area of designing, qualifying, and licensing of computer-based instrumentation and control systems. The authors describe the experience gained in designing three safety-related systems, that include a Programmable Logic Controller (PLC) based Safeguard Load Sequencer for NSP Prairie Island, a digital Containment Isolation monitoring system for TVA Browns Ferry, and a study that was conducted for EPRI/NSP regarding a PLC-based Reactor Protection system. This article presents the benefits to be gained in replacing existing, outdated equipment with new advanced instrumentation

Patient-reported outcome (PRO) instruments for children and adolescents are often included in clinical trials with the intention of collecting data to support claims in a medical product label. The purpose of the current task force report is to recommend good practices for pediatric PRO research that is conducted to inform regulatory decision making and support claims made in medical product labeling. The recommendations are based on the consensus of an interdisciplinary group of researchers who were assembled for a task force associated with the International Society for Pharmacoeconomics and Outcomes Research (ISPOR). In those areas in which supporting evidence is limited or in which general principles may not apply to every situation, this task force report identifies factors to consider when making decisions about the design and use of pediatric PRO instruments, while highlighting issues that require further research. Five good research practices are discussed: 1) Consider developmental differences and determine age-based criteria for PRO administration: Four age groups are discussed on the basis of previous research (<5 years old, 5-7 years, 8-11 years, and 12-18 years). These age groups are recommended as a starting point when making decisions, but they will not fit all PRO instruments or the developmental stage of every child. Specific age ranges should be determined individually for each population and PRO instrument. 2) Establish content validity of pediatric PRO instruments: This section discusses the advantages of using children as content experts, as well as strategies for concept elicitation and cognitive interviews with children. 3) Determine whether an informant-reported outcome instrument is necessary: The distinction between two types of informant-reported measures (proxy vs. observational) is discussed, and recommendations are provided. 4) Ensure that the instrument is designed and formatted appropriately for the target age group.

To assess the strength of association between graded groups of oral health status and self-reported functional dependence in community-dwelling older adults. Population-based cross-sectional study. National Health and Nutritional Examination Survey (NHANES) 1999 to 2004. Three thousand eight hundred fifty-six participants aged 60 and older (mean age 71.2) without missing values in the examined correlates. Oral health status was evaluated according to edentulism, severity of periodontal disease, and recommendation of periodontal care and compared with that of healthy controls. Self-reported functional dependence was assessed according to 19 questions in five domains: activities of daily living (ADLs), instrumental activities of daily living (IADLs), leisure and social activities (LSAs), lower extremity mobility (LEM), and general physical activities (GPAs). After controlling for demographic and dental variables, health-related behaviors, C-reactive protein, and comorbidities, edentulism was significantly associated with disability in IADLs (odds ratio (OR)=1.58), LSAs (OR=1.63), LEM (OR=1.31), and GPAs (OR=1.45) compared with healthy controls. Likewise, severe periodontitis was associated with disability in IADLs (OR=1.58), LSAs (OR=1.70), and LEM (OR=1.63). The trends toward disability in IADLs, LSAs, LEM, and GPAs were statistically significant across increasing severity of oral health problems. Poor oral health, specifically edentulism and severe periodontitis, is associated with multiple domains of late-life disability, but a causal relationship cannot be established based on current study design. © 2011, Copyright the Authors.

Benning, Stephen D.; Patrick, Christopher J.; Salekin, Randall T.; Leistico, Anne-Marie R.

2008-01-01

Psychopathy has been conceptualized as a personality disorder with distinctive interpersonal-affective and behavioral deviance features. The authors examine correlates of the factors of the Psychopathic Personality Inventory (PPI), Self-Report Psychopathy–II (SRP-II) scale, and Antisocial Process Screening Device (APSD) to understand similarities and differences among the constructs embodied in these instruments. PPI Fearless Dominance and SRP-II Factor 1 were negatively related to most personality disorder symptoms and were both predicted by high Dominance and low Neuroticism. In addition, PPI Fearless Dominance correlated positively with antisocial personality features, although SRP-II Factor 1 did not. In contrast, PPI Impulsive Antisociality, SRP-II Factor 2, and both APSD factors correlated with antisocial personality features and symptoms of nearly all personality disorders, and were predicted by low Love. Results suggest ways in which the measurement of the constructs in each instrument may be improved. PMID:16123248

2011-09-01

Micro Unmanned Aerial Vehicles (MUAV) must calculate its spatial position to control the flight dynamics, which is done by Inertial Measurement Units (IMUs). MEMS Inertial sensors have made possible to reduce the size and power consumption of such units. Commonly the flight instrumentation operates independently of the main processor. This work presents an instrumentation block design, which reduces size and power consumption of the complete system of a MUAV. This is done by coupling the inertial sensors to the main processor without considering any intermediate level of processing aside. Using Real Time Operating Systems (RTOS) reduces the number of intermediate components, increasing MUAV reliability. One advantage is the possibility to control several different sensors with a single communication bus. This feature of the MEMS sensors makes a smaller and less complex MUAV design possible.

Toward Establishing the Validity of the Resource Interpreter's Self-Efficacy Instrument

Science.gov (United States)

Smith, Grant D.

Interpretive rangers serve as one of the major educational resources that visitors may encounter during their visit to a park or other natural area, yet our understanding of their professional growth remains limited. This study helps address this issue by developing an instrument that evaluates the beliefs of resource interpreters regarding their capabilities of communicating with the public. The resulting 11-item instrument was built around the construct of Albert Bandura's self-efficacy theory (Bandura, 1977, 1986, 1997), used guidelines and principles developed over the course of 30 years of teacher efficacy studies (Bandura, 2006; Gibson & Dembo, 1984; Riggs & Enochs, 1990; Tschannen-Moran & Hoy, 2001; Tschannen-Moran, Hoy, & Hoy, 1998), and probed areas of challenge that are unique to the demands of resource interpretation (Brochu & Merriman, 2002; Ham, 1992; Knudson, Cable, & Beck, 2003; Larsen, 2003; Tilden, 1977). A voluntary convenience sample of 364 National Park Service rangers was collected in order to conduct the statistical analyses needed to winnow the draft instrument down from 47 items in its original form to 11 items in its final state. Statistical analyses used in this process included item-total correlation, index of discrimination, exploratory factor analysis, and confirmatory factor analysis.

Full Text Available The aim of this study is to investigate the relationships between the affective learning needs namely, self-efficacy and locus of control, learning efforts and academic achievement among engineering students. For this purpose, a survey was conducted on first year engineering students from two technical universities in Malaysia. Self-efficacy and locus of control were assessed using existing instruments while learning efforts were assessed using a specifically designed instrument based on Carbonaro’s model of learning effort. Academic achievement data were based on cumulative grade point average (CGPA obtained from self-report by participants. The findings indicate that females engineering students tend to have higher self-efficacy compared to males while both groups have similar locus of control and invest in similar learning efforts. Only locus of control is found to be related to academic achievement while self-efficacy is found to be related to efforts. In conclusion, locus of control seems to be an important factor in predicting academic achievement among engineering students.

The Self-assessment Practices of Hong Kong Secondary Students: Findings with a New Instrument.

Science.gov (United States)

Yan, Zi

Self-assessment is a core skill that enables students to engage in self-regulated learning. The purpose of this study was to examine the psychometric properties of a Self-assessment Practice Scale and to depict the characteristics of self-assessment practices of Hong Kong secondary students using this newly developed instrument. A total of 6,125 students from 10 Hong Kong secondary schools completed the survey. Both Rasch and factor analyses revealed a two-dimension scale structure (i.e., Self-directed Feedback Seeking and Self-reflection). The two subscales demonstrated acceptable psychometric properties and suggestions for further improvement were proposed. The findings regarding self-assessment practices of secondary students indicated that, in general, students were quite used to engaging in self-reflection based on available feedback, but they were less disposed to taking the initiative to seek feedback on their own performance. Key demographic variables, e.g., gender and year level, played important roles in students' self-assessment practices. Girls had significantly higher self-assessment measures on both scales than did boys. Junior students had higher measures on both scales than did their senior counterparts. Implications and directions for future research were discussed.

An instrumented capsule was developed to be able to measure fuel characteristics, such as fuel temperature, internal pressure of fuel rod, fuel pellet elongation, and neutron flux, etc., during the irradiation test of nuclear fuel in Hanaro. The instrumented capsule(02F-11K) for measuring and monitoring and monitoring fuel centerline temperature and neutron flux was designed and manufactured. It was successfully irradiated in the test hole OR5 of Hanaro from March 14, 2003 to June 1, 2003 (53.84 full power days at 24 MW). In the year of 2004, 3 test fuel rods and the instrumented capsule(03F-05K) were designed and manufactured to measure fuel centerline temperature, internal pressure of fuel rod, and fuel axial deformation during irradiation test. This capsule was irradiated in the test hole OR5 of Hanaro reactor from April 26, 2004 to October 1, 2004 (59.5 EFPD at 24 {approx} 30 MW). The six typed dual instrumented fuel rods, which allow for two characteristics to be measured simultaneously in one fuel rod, have been designed and manufactured to enhance the efficiency of the irradiation test using the instrumented fuel capsule. The 05F-01K instrumented fuel capsule was designed and manufactured for a design verification test of the three dual instrumented fuel rods. The irradiation test of the 05F-01K instrumented fuel capsule will be carried out at the OR5 vertical experimental hole of Hanaro.

Robust structural design against self-excited vibrations

CERN Document Server

Spelsberg-Korspeter, Gottfried

2013-01-01

This book studies methods for a robust design of rotors against self-excited vibrations. The occurrence of self-excited vibrations in engineering applications if often unwanted and in many cases difficult to model. Thinking of complex systems such as machines with many components and mechanical contacts, it is important to have guidelines for design so that the functionality is robust against small imperfections. This book discusses the question on how to design a structure such that unwanted self-excited vibrations do not occur. It shows theoretically and practically that the old design rule to avoid multiple eigenvalues points toward the right direction and have optimized structures accordingly. This extends results for the well-known flutter problem in which equations of motion with constant coefficients occur to the case of a linear conservative system with arbitrary time periodic perturbations.

The reliability, validity, and accuracy of self-reported absenteeism from work: a meta-analysis.

Science.gov (United States)

Johns, Gary; Miraglia, Mariella

2015-01-01

Because of a variety of access limitations, self-reported absenteeism from work is often employed in research concerning health, organizational behavior, and economics, and it is ubiquitous in large scale population surveys in these domains. Several well established cognitive and social-motivational biases suggest that self-reports of absence will exhibit convergent validity with records-based measures but that people will tend to underreport the behavior. We used meta-analysis to summarize the reliability, validity, and accuracy of absence self-reports. The results suggested that self-reports of absenteeism offer adequate test-retest reliability and that they exhibit reasonably good rank order convergence with organizational records. However, people have a decided tendency to underreport their absenteeism, although such underreporting has decreased over time. Also, self-reports were more accurate when sickness absence rather than absence for any reason was probed. It is concluded that self-reported absenteeism might serve as a valid measure in some correlational research designs. However, when accurate knowledge of absolute absenteeism levels is essential, the tendency to underreport could result in flawed policy decisions.

The aim of the study was to explore relationships between self-reported adherence, antiretroviral drug concentration measurement (TDM) and self-reported symptoms. We systematically administered to human immunodeficiency (HIV)-infected outpatients a questionnaire evaluating measures of self-reported adherence (missing doses during last week, deviations from the prescribed timing of therapy, self-initiated discontinuations for > 24 or 48 h, exhausting drugs and present sense of how patients are taking therapy) and a panel of referred symptoms (a symptom score was built summing self-reported scores for each listed symptom). We selected patients who completed the questionnaire and also had a TDM (mainly reflecting adherence in the past few days or weeks), thus comparing these two tools as measures of adherence. A total of 130 patients (64.6% males, median age 44 years, 76.2% with HIV RNA HIV RNA symptom score was associated with a lower self-reported adherence and with a higher proportion of undetectable drug levels. Self-reported adherence and TDM showed a correlation and seemed to be comparable tools for adherence estimation. Self-reported symptoms were associated with lower adherence and undetectable drug levels.

To analyze the contents and formats of general self-reported questionnaires on disability that are designed for and/or are widely applied in the elderly population to depict a complete picture of this field and help researchers to choose proper tools more efficiently. A broad systematic literature search was performed in September 2013 and included the following databases: MEDLINE, EMBASE, CINAHL, PsycINFO, and PROQOLID. The publication language was limited to English and Chinese. Two review authors independently performed the study selection and data extraction. All of the included instruments were extracted and classified using the International Classification of Functioning, Disability, and Health framework. Of 5569 articles retrieved from the searches and 156 articles retrieved from the pearling, 22 studies (including 24 questionnaires) fulfilled the inclusion criteria. From these, 42 different domains and 458 items were extracted. The most frequently used questionnaire was the Barthel Index followed by the Lawton and Brody Instrumental Activities of Daily Living Scale and the Katz Index of Activities of Daily Living, respectively. The contents and formats of the questionnaires varied considerably. Activities and participation were the most commonly assessed dimensions. In addition, the Activities of Daily Living, mobility and the Instrumental Activities of Daily Living Scale were the most common domains assessed among the included questionnaires. Among the 24 included questionnaires, the most frequently used questionnaires were the Barthel Index, Lawton and Brody Instrumental Activities of Daily Living Scale, and Katz Index of Activities of Daily Living. The content and format of the questionnaires varied considerably, but none of the questionnaires covered all essential dimensions of the International Classification of Functioning, Disability, and Health framework.

Oropharyngeal dysphagia is a swallowing disorder with signs and symptoms which may be present in older adults, but they are rarely noticed as a health concern by older people. The earliest possible identification of this clinical condition is needed by self-reported population-based screening questionnaire, which are valid and reliable for preventing risks to nutritional status, increased morbidity and mortality. The aim of this systematic review was to identify self-reported screening questionnaires for oropharyngeal dysphagia in older adults to evaluate their methodological quality for population-based studies. An extensive search of electronic databases (PubMed (MEDLINE), Ovid MEDLINE(R), Scopus, Cochrane Library, CINAHL, Web of Science (WOS), PsycINFO (APA), Lilacs and Scielo) was conducted in the period from April to May 2017 using previously established search strategies by the two evaluators. The methodological quality and the psychometric properties of the included studies were evaluated by the COSMIN (Consensus based Standards for the selection of health Measurement Instruments) checklist and the quality criteria of Terwee and colleagues, respectively. The analysed information was extracted from three articles which had conducted studies on the prevalence of oropharyngeal dysphagia by self-reported screening questionnaires, showing poor methodological quality and flaws in the methodological description to demonstrate its psychometric properties. This study did not find any self-reported screening questionnaires for oropharyngeal dysphagia with suitable methodological quality and appropriate evidence in its psychometric properties for elders. Therefore, the self-reported questionnaires within the diagnostic proposal require greater details in its process for obtaining valid and reliable evidence. © 2018 John Wiley & Sons A/S and The Gerodontology Association.

Interest in assessing Personality Disorders (PDs) in association with anorexia nervosa (AN) and bulimia nervosa (BN) has been accompanied by the development of several structured interview and self-report measures. In an attempt to see how the self-report Millon Clinical Multiaxial Inventory (MCMI-II) compared with the Structured Clinical Interview for DSM-III-R (SCID-II) in the assessment of PDs, we gave both instruments to 43 inpatients with a diagnosis of AN or BN. Correlation coefficient values for both categorical and dimensional comparisons were generally less than .4. Although comparable rates of positive PDs occurred for each of the three clusters (A: 30.2% vs. 34.9%, B: 25.6% vs. 18.6%, and C: 62.8% vs. 81.4% for SCID-II vs. MCMI-II), agreement for individual diagnosis and individual subjects was poor. In conclusion, the MCMI-II did not prove to be a reliable instrument for assessing axis II PDs in patients with AN and BN when compared with the SCID-II.

The multi-pinholes and multi-slits as SANS collimator for medium flux Dhruva rearctor have been proposed and their designs have been validated using McStas simulations. Various instrument configurations to achieve different minimum wave vector transfers in scattering experiments are envisioned. These options enable smooth access to minimum wave vector transfers as low as ~ 6×10{sup −4} Å{sup −1} with a significant improvement in neutron intensity, allowing faster measurements. Such angularly well defined and intense neutron beam will allow faster SANS studies of agglomerates larger than few tens of nm.

Solar Probe Plus will be the first, fastest, and closest mission to the sun, providing the first direct sampling of the sub-Alfvenic corona. The Solar Probe Cup (SPC) is a unique re-imagining of the traditional Faraday Cup design and materials for immersion in this high temperature environment. Sending an instrument of this type into a never-seen particle environment requires extensive characterization prior to launch to establish sufficient measurement accuracy and instrument response. To reach this end, a slew of tests for allowing SPC to see ranges of appropriate ions and electrons, as well as a facility that reproduces solar photon spectra and fluxes for this mission. Having already tested the SPC at flight like temperatures with no significant modification of the noise floor, we recently completed a round of particle testing to see if the deviations in Faraday Cup design fundamentally change the operation of the instrument. Results and implications from these tests will be presented, as well as performance comparisons to cousin instruments such as those on the WIND spacecraft.

Lilienfeld, P.

1975-01-01

The theory, instrument design aspects and applications of beta-radiation attenuation for the measurement of the mass concentration of airborne particulates are reviewed. Applicable methods of particle collection, beta sensing configurations, source ( 63 Ni, 14 C, 147 Pr, 85 Kr) and detector design criteria, electronic signal processing, digital control and instrument programming techniques are treated. Advantages, limitations and error sources of beta-attenuation instrumentation are analyzed. Applications to industrial dust measurements, source testing, ambient monitoring, and particle size analysis are the major areas of practical utilization of this technique, and its inherent capability for automated and unattended operation provides compatibility with process control synchronization and alarm, telemetry, and incorporation into pollution monitoring network sensing stations.

The utility of self-report measures of physical activity (PA) in youth can be greatly enhanced by calibrating self-report output against objectively measured PA data.This study demonstrates the potential of calibrating self-report output against objectively measured physical activity (PA) in youth by using a commonly used self-report tool called the Physical Activity Questionnaire (PAQ). A total of 148 participants (grades 4 through 12) from 9 schools (during the 2009-2010 school year) wore an Actigraph accelerometer for 7 days and then completed the PAQ. Multiple linear regression modeling was used on 70% of the available sample to develop a calibration equation and this was cross validated on an independent sample of participants (30% of sample). A calibration model with age, gender, and PAQ scores explained 40% of the variance in values for the percentage of time in moderate-to-vigorous PA (%MVPA) measured from the accelerometers (%MVPA = 14.56 - (sex*0.98) - (0.84*age) + (1.01*PAQ)). When tested on an independent, hold-out sample, the model estimated %MVPA values that were highly correlated with the recorded accelerometer values (r = .63) and there was no significant difference between the estimated and recorded activity values (mean diff. = 25.3 ± 18.1 min; p = .17). These results suggest that the calibrated PAQ may be a valid alternative tool to activity monitoring instruments for estimating %MVPA in groups of youth.

The Franco-Italian VIMOS instrument is a VIsible imaging Multi-Object Spectrograph with outstanding multiplex capabilities, allowing to take spectra of more than 800 objects simultaneously, or integral field spectroscopy mode in a 54x54 arcsec area. VIMOS is being installed at the Nasmyth focus of the third Unit Telescope of the European Southern Observatory Very Large Telescope (VLT) at Mount Paranal in Chile. This paper will describe the analysis, the design and the implementation of the VIMOS Instrument Control System, using UML notation. Our Control group followed an Object Oriented software process while keeping in mind the ESO VLT standard control concepts. At ESO VLT a complete software library is available. Rather than applying waterfall lifecycle, ICS project used iterative development, a lifecycle consisting of several iterations. Each iteration consisted in : capture and evaluate the requirements, visual modeling for analysis and design, implementation, test, and deployment. Depending of the project phases, iterations focused more or less on specific activity. The result is an object model (the design model), including use-case realizations. An implementation view and a deployment view complement this product. An extract of VIMOS ICS UML model will be presented and some implementation, integration and test issues will be discussed.

Haitao Li

2016-12-01

Full Text Available Modern biosensors play a critical role in healthcare and have a quickly growing commercial market. Compared to traditional optical-based sensing, electrochemical biosensors are attractive due to superior performance in response time, cost, complexity and potential for miniaturization. To address the shortcomings of traditional benchtop electrochemical instruments, in recent years, many complementary metal oxide semiconductor (CMOS instrumentation circuits have been reported for electrochemical biosensors. This paper provides a review and analysis of CMOS electrochemical instrumentation circuits. First, important concepts in electrochemical sensing are presented from an instrumentation point of view. Then, electrochemical instrumentation circuits are organized into functional classes, and reported CMOS circuits are reviewed and analyzed to illuminate design options and performance tradeoffs. Finally, recent trends and challenges toward on-CMOS sensor integration that could enable highly miniaturized electrochemical biosensor microsystems are discussed. The information in the paper can guide next generation electrochemical sensor design.

2012-01-01

A number of rotary nickel-titanium (NiTi) systems have been developed to provide better, faster, and easier cleaning and shaping of the root canal system, and recently, rotary NiTi systems designed for root canal retreatment have been introduced. Because the main problem with the rotary NiTi files is fracture, the aim of this study was to compare the cyclic fatigue resistance of 3 different rotary NiTi systems designed for root canal retreatment. Total of 60 instruments of 3 different rotary NiTi systems designed for root canal retreatment were used in this study. Twenty R-Endo R3, 20 ProTaper D3, and 20 Mtwo R (Retreatment) 25.05 instruments were tested. Cyclic fatigue testing of instruments was performed by using a device that allowed the instruments to rotate freely inside an artificial canal. Each instrument was rotated until fracture occurred, and the number of cycles to fracture for each instrument was calculated. Representative samples were also evaluated under a scanning electron microscope to confirm the fracture was flexural. Data were analyzed by using 1-way analysis of variance test. R-Endo R3 instruments showed better cyclic fatigue resistance than ProTaper D3 and Mtwo R 25.05 instruments, and the difference was statistically significant (P instruments were more resistant to fatigue failure than ProTaper D3 and Mtwo R 25.05.

Impact of Passive Safety on FHR Instrumentation Systems Design and Classification

International Nuclear Information System (INIS)

Holcomb, David Eugene

2015-01-01

Fluoride salt-cooled high-temperature reactors (FHRs) will rely more extensively on passive safety than earlier reactor classes. 10CFR50 Appendix A, General Design Criteria for Nuclear Power Plants, establishes minimum design requirements to provide reasonable assurance of adequate safety. 10CFR50.69, Risk-Informed Categorization and Treatment of Structures, Systems and Components for Nuclear Power Reactors, provides guidance on how the safety significance of systems, structures, and components (SSCs) should be reflected in their regulatory treatment. The Nuclear Energy Institute (NEI) has provided 10 CFR 50.69 SSC Categorization Guideline (NEI-00-04) that factors in probabilistic risk assessment (PRA) model insights, as well as deterministic insights, through an integrated decision-making panel. Employing the PRA to inform deterministic requirements enables an appropriately balanced, technically sound categorization to be established. No FHR currently has an adequate PRA or set of design basis accidents to enable establishing the safety classification of its SSCs. While all SSCs used to comply with the general design criteria (GDCs) will be safety related, the intent is to limit the instrumentation risk significance through effective design and reliance on inherent passive safety characteristics. For example, FHRs have no safety-significant temperature threshold phenomena, thus enabling the primary and reserve reactivity control systems required by GDC 26 to be passively, thermally triggered at temperatures well below those for which core or primary coolant boundary damage would occur. Moreover, the passive thermal triggering of the primary and reserve shutdown systems may relegate the control rod drive motors to the control system, substantially decreasing the amount of safety-significant wiring needed. Similarly, FHR decay heat removal systems are intended to be running continuously to minimize the amount of safety-significant instrumentation needed to initiate

Studies of clinical cohorts and retrospective reports have identified psychiatric disorders as paramount risk factors for suicide. Much less is known about how self-reported mental health is related to completed suicide. To study the relation between self-reported mental health and risk of completed suicide, the authors prospectively followed a population-based Norwegian cohort of 61,588 men and 69,774 women aged 39-44 years for an average of 10.4 years between 1994 and 2007. Self-reported mental health was measured using an instrument based on the Hopkins Symptom Checklist and the General Health Questionnaire. Completed suicides were registered in the official Norwegian Cause of Death Registry. Females reported higher levels of mental distress than males. In comparison with persons reporting the fewest mental health symptoms, the adjusted hazard ratio for suicide increased from 1.8 (95% confidence interval (CI): 1.1, 2.9) in the moderately depressed group to 8.9 (95% CI: 4.4, 18.2) in the most depressed group. The risk difference was greatest in males. At each level of the mental health index, males had double the risk of suicide of females (hazard ratio = 2.3, 95% CI: 1.5, 3.3). This study shows a dose-response effect of self-reported mental health problems on completed suicide and replicates the gender paradox observed in the general population with prospective data.

Cross-sectional validation of the Aging Perceptions Questionnaire: a multidimensional instrument for assessing self-perceptions of aging.

LENUS (Irish Health Repository)

Barker, Maja

2007-01-01

BACKGROUND: Self-perceptions of aging have been implicated as independent predictors of functional disability and mortality in older adults. In spite of this, research on self-perceptions of aging is limited. One reason for this is the absence of adequate measures. Specifically, there is a need to develop a measure that is theoretically-derived, has good psychometric properties, and is multidimensional in nature. The present research seeks to address this need by adopting the Self-Regulation Model as a framework and using it to develop a comprehensive, multi-dimensional instrument for assessing self-perceptions of aging. This study describes the validation of this newly-developed instrument, the Aging Perceptions Questionnaire (APQ). METHODS: Participants were 2,033 randomly selected community-dwelling older (+65 yrs) Irish adults who completed the APQ alongside measures of physical and psychological health. The APQ assesses self-perceptions of aging along eight distinct domains or subscales; seven of these examine views about own aging, these are: timeline chronic, timeline cyclical, consequences positive, consequences negative, control positive, control negative, and emotional representations; the eighth domain is the identity domain and this examines the experience of health-related changes. RESULTS: Mokken scale analysis showed that the majority of items within the views about aging subscales were strongly scalable. Confirmatory factor analysis also indicated that the model provided a good fit for the data. Overall, subscales had good internal reliabilities. Hierarchical linear regression was conducted to investigate the independent contribution of APQ subscales to physical and psychological health and in doing so determine the construct validity of the APQ. Results showed that self-perceptions of aging were independently related to physical and psychological health. Mediation testing also supported a role for self-perceptions of aging as partial mediators in

An instrument for measurement of 125I with automatic efficiency correction

International Nuclear Information System (INIS)

Holford, R.M.

1979-10-01

Counting efficiencies for 125 I are often uncertain because of self-absorption of the low-energy radiation. A special purpose instrument, AEP-5285, has been designed to simplify the measurement of 125 I activities using a known technique in which the observed counting rate is compensated for self-absorption and any other uncertainties in the counting efficiency by making use of the coicidence properties of the radiation. The instrument contains pulse amplifiers, discriminators to define the energy regions of interest, and operational amplifier circuits to perform the necessary calculations automatically, and it displays an estimate of the source activity in becquerels.

2016-10-01

Full Text Available One of the most important features which e-learning tools and environments must possess within the scope of lifelong learning is self-directed learning, which can be considered as a form of self-learning. The aim of this study was to determine, based on the views and recommendations of experts, interface design principles for the development of educational web interfaces that will support the self-directed learning of adults. This descriptive study was conducted with the contribution of 12 academicians specializing in interface design and self-directed learning. Within the scope of the study, new interfaces features were identified based on an evaluation of the literature on interface designs for self-directed learning, and the views of subject experts. Based on the study results, it was determined that interface designs supporting self-directed learning must possess five basic features, which include being user-directed, ensuring variety, being supported by learning analytics, being motivational, and being sharing-oriented.

The various radiations encountered in radiological protection cover a wide range of energies and radiation measurements have to be carried out under an equally broad spectrum of environmental conditions. This report is one of a series intended to give information on the performance characteristics of radiological protection instruments, to assist in the selection of appropriate instruments for a given purpose, to interpret the results obtained with such instruments, and, in particular, to know the likely sources and magnitude of errors that might be associated with measurements in the field. The radiation, electrical and environmental characteristics of radiation protection instruments are considered together with those aspects of the construction which make an instrument convenient for routine use. To provide consistent criteria for instrument performance, the range of tests performed on any particular class of instrument, the test methods and the criteria of acceptable performance are based broadly on the appropriate Recommendations of the International Electrotechnical Commission. The radiations in the tests are, in general, selected from the range of reference radiations for instrument calibration being drawn up by the International Standards Organisation. Normally, each report deals with the capabilities and limitations of one model of instrument and no direct comparison with other instruments intended for similar purposes is made, since the significance of particular performance characteristics largely depends on the radiations and environmental conditions in which the instrument is to be used. The results quoted here have all been obtained from tests on instruments in routine production, with the appropriate measurements being made by the NRPB. This report provides a concise summary of measurements of the more important performance characteristics of radiation protection dose rate or exposure rate survey instruments which have been assessed by NRPB as part

Motivation and Pleasure Scale-Self-Report (MAP-SR): Validation of the German version of a self-report measure for screening negative symptoms in schizophrenia.

Engel, Maike; Lincoln, Tania Marie

Validated self-report instruments could provide a time efficient screening method for negative symptoms in people with schizophrenia. The aim of this study was to examine the psychometric properties of a German version of the Motivation and Pleasure Scale-Self-Report (MAP-SR) which is based on the Clinical Assessment Interview for Negative Symptoms (CAINS). In- and outpatients (N=50) with schizophrenia or schizoaffective disorder were assessed with standardized interviews and questionnaires on negative and positive symptoms and general psychopathology in schizophrenia, depression, and global functioning. The German version of the MAP-SR showed high internal consistency. Convergent validity was supported by significant correlations between the MAP-SR with the experience sub-scale of the CAINS and the negative symptom sub-scale of the Positive and Negative Syndrome Scale. The MAP-SR also exhibited discriminant validity indicated by its non-significant correlations with positive symptoms and general psychopathology, which is in line with the findings for the original version of the MAP-SR. However, the MAP-SR correlated moderately with depression. The German MAP-SR appears to be a valid and suitable diagnostic tool for the identification of negative symptoms in schizophrenia.

Chakrabarty, Subhra

2014-10-01

In a recent study, Dussault, Frenette, and Fernet (2013) developed a 21-item self-report instrument to measure leadership based on Bass's (1985) transformational/transactional leadership paradigm. The final specification included a third-order dimension (leadership), two second-order dimensions (transactional leadership and transformational leadership), and a first-order dimension (laissez-faire leadership). This note focuses on the need for assessing convergent and discriminant validity of the scale, and on ruling out the potential for common method bias.

An initial look at sibling reports on children's behavior: comparisons with children's self-reports and relations with siblings' self-reports and sibling relationships.

Epkins, C C; Dedmon, A M

1999-10-01

The authors examined siblings' reports of children's depression, anxiety, and aggression, and their reports of the sibling relationship, and compared them with children's self-reports. In two samples, including 169 sibling pairs (age M = 9.98 years, SD = 1.51), no significant differences emerged in the levels of depression and anxiety found in siblings' reports of children's behavior and children's self-reports, although siblings reported children to have significantly higher levels of aggression than the children self-reported. Age, the difference in ages between siblings, sex, and sibling sex were not related to siblings' reports of children's behavior. The relations between children's and siblings' reports of children's behavior were significant, yet moderate (average r = .22). Both siblings' self-reports of internalizing behavior and their perceptions of aspects of the sibling relationship (affection, rivalry, hostility, and satisfaction with the sibling relationship) explained significant, and unique, variance in siblings' reports of children's internalizing behavior. The findings for aggressive behavior were similar, although siblings' perceptions of affection in the sibling relationship were not significantly related to their reports of children's aggression. The potential uses and benefits of sibling reports of children's behavior, and sibling and family relationships, are discussed.

Rationally Designed, Multifunctional Self-Assembled Nanoparticles for Covalently Networked, Flexible and Self-Healable Superhydrophobic Composite Films.

Lee, Yujin; You, Eun-Ah; Ha, Young-Geun

2018-03-21

For constructing bioinspired functional films with various superhydrophobic functions, including self-cleaning, anticorrosion, antibioadhesion, and oil-water separation, hydrophobic nanomaterials have been widely used as crucial structural components. In general, hydrophobic nanomaterials, however, cannot form strong chemical bond networks in organic-inorganic hybrid composite films because of the absence of chemically compatible binding components. Herein, we report the rationally designed, multifunctional self-assembled nanoparticles with tunable functionalities of covalent cross-linking and hydrophobicity for constructing three-dimensionally interconnected superhydrophobic composite films via a facile solution-based fabrication at room temperature. The multifunctional self-assembled nanoparticles allow the systematic control of functionalities of composite films, as well as the stable formation of covalently linked superhydrophobic composite films with excellent flexibility (bending radii of 6.5 and 3.0 mm, 1000 cycles) and self-healing ability (water contact angle > 150°, ≥10 cycles). The presented strategy can be a versatile and effective route to generating other advanced functional films with covalently interconnected composite networks.

Validity of self-reported criminal justice system involvement in substance abusing women at five-year follow-up

Directory of Open Access Journals (Sweden)

Hesse Morten

2008-01-01

Full Text Available Abstract Background Few studies have compared self-reported criminal behaviour with high-quality databases of criminal offences and judicial sanctions. Self-reported problems from drug abusers are generally believed to be valid. We assessed the validity of self-reported theft, drug offences and prison sentences from a five-year follow-up of female substance abusers who were originally treated in a compulsory care unit in Lund, run by the Swedish Board of Institutional Care. Methods Data from a total of 106 of a consecutive sample of 132 women inter-viewed in a five-year follow-up. All were thoroughly assessed for somatic complaints, psychiatric and psychological problems, background factors with standardized instruments. Data over the five years were linked to official records of judicial sanctions, retrieved from The National Council for Crime Prevention, Stockholm, Sweden. Register data have a full cover for the whole cohort. The current data base contain full data back to 1975 up to 2004. Results Agreement was assessed for each year, as well as for the total period. Statistical control was performed for other types of crimes and prison. Although statistically significant, agreement was modest, and in contrast to previous studies, patients under-reported violence charges. Conclusion The findings suggest that self-reports of criminal behaviour from women can be used with some caution, and that the validity of self-report may vary between types of criminal justice system involvement.

Ishida, Yoshiteru

2015-01-01

This book describes the struggle to introduce a mechanism that enables next-generation information systems to maintain themselves. Our generation observed the birth and growth of information systems, and the Internet in particular. Surprisingly information systems are quite different from conventional (energy, material-intensive) artificial systems, and rather resemble biological systems (information-intensive systems). Many artificial systems are designed based on (Newtonian) physics assuming that every element obeys simple and static rules; however, the experience of the Internet suggests a different way of designing where growth cannot be controlled but self-organized with autonomous and selfish agents. This book suggests using game theory, a mechanism design in particular, for designing next-generation information systems which will be self-organized by collective acts with autonomous components. The challenge of mapping a probability to time appears repeatedly in many forms throughout this book. The book...

Stress is the most common patient-reported seizure precipitant. We aimed to determine mood and epilepsy characteristics of people who report stress-precipitated seizures. Sequential patients at a tertiary epilepsy center were surveyed about stress as a seizure precipitant. We asked whether acute (lasting minutes-hours) or chronic (lasting days-months) stress was a seizure precipitant, whether stress reduction had been tried, and what effect stress reduction had on seizure frequency. We collected information on antiepileptic drugs, history of depression and anxiety disorder, prior or current treatment for depression or anxiety, and scores on the Neurological Disorders Depression Inventory (NDDI-E) and Generalized Anxiety Disorders-7 (GAD-7) instruments, which are administered at every visit in our Epilepsy Center. We also asked whether respondents thought that they could predict their seizures to determine if stress as a seizure precipitant was correlated with seizure self-prediction. Two hundred sixty-six subjects were included: 219 endorsed stress as a seizure precipitant [STRESS (+)] and 47 did not [STRESS (-)]. Among STRESS (+) subjects, 85% endorsed chronic stress as a seizure precipitant, and 68% endorsed acute stress as a seizure precipitant. In STRESS (+) subjects, 57% had used some type of relaxation or stress reduction method (most commonly yoga, exercise and meditation), and, of those who tried, 88% thought that these methods improved seizures. Among STRESS (-) subjects, 25% had tried relaxation or stress reduction, and 71% thought that seizures improved. Although univariate analysis showed multiple associations with stress as a seizure precipitant, in the multivariable logistic regression, only the GAD-7 score was associated with STRESS (+) (OR = 1.18 [1.03-1.35], p = 0.017). Subjects who reported stress as a seizure precipitant were more likely to report an ability to self-predict seizures (p < 0.001). Stress-precipitated seizures are commonly reported

In this paper, a portable diagnostic instrument was designed and tested, which can measure the normalized difference vegetation index (NDVI) and structure insensitive pigment index (SIPI) of crop canopy in field. The instrument have a valid survey area of 1 m*1 m when the height between instrument and the ground was fixed to 1.3 meter The crop growth condition can be assessed based on their NDVI and SIPI values, so it will be very important for crop management to get these values. The instrument uses sunlight as its light source. There are six special different photoelectrical detectors within red, blue and near infrared bands, which are used for detecting incidence sunlight and reflex light from the canopy of crop. This optical instrument includes photoelectric detector module, signal process and A/D convert module, the data storing and transmission module and human-machine interface module. The detector is the core of the instrument which measures the spectrums at special bands. The microprocessor calculates the NDVI and SIPI value based on the A/D value. And the value can be displayed on the instrument's LCD, stored in the flash memory of instrument and can also be uploaded to PC through the PC's RS232 serial interface. The prototype was tested in the crop field at different view directions. This paper also provided the method of calibration, the results showed that the average measurement error to SIPI value of instrument was 5.25% and the average measurement error to NDVI value in vegetation-covered region is 6.40%. It reveals the on-site and non-sampling mode of crop growth monitoring by fixed on the agricultural machine traveling in the field.

This study examines how self-consciousness is defined and assessed using self-report questionnaires (Self-Consciousness Scale (SCS), Self-Reflection and Insight Scale, Self-Absorption Scale, Rumination-Reflection Questionnaire, and Philadelphia Mindfulness Scale). Authors of self-report measures suggest that self-consciousness can be distinguished by its private/public aspects, its adaptive/maladaptive applied characteristics, and present/past experiences. We examined these claims in a study using 602 young adults to whom the aforementioned scales were administered. Data were analyzed as follows: (1) correlation analysis to find simple associations between the measures; (2) factorial analysis using Oblimin rotation of total scores provided from the scales; and (3) factorial analysis considering the 102 items of the scales all together. It aimed to clarify relational patterns found in the correlations between SCSs, and to identify possible latent constructs behind these scales. Results support the adaptive/maladaptive aspects of self-consciousness, as well as distinguish to some extent public aspects from private ones. However, some scales that claimed to be theoretically derived from the concept of Private Self-Consciousness correlated with some of its public self-aspects. Overall, our findings suggest that while self-reflection measures tend to tap into past experiences and judged concepts that were already processed by the participants’ inner speech and thoughts, the Awareness measure derived from Mindfulness Scale seems to be related to a construct associated with present experiences in which one is aware of without any further judgment or logical/rational symbolization. This sub-scale seems to emphasize the role that present experiences have in self-consciousness, and it is argued that such a concept refers to what has been studied by phenomenology and psychology over more than 100 years: the concept of pre-reflective self-conscious.

Many childhood deaths in the United States occur in pediatric intensive care units (PICUs) and parents have special needs in this death context. As an interdisciplinary research team, we discuss conceptual and design issues encountered in creating a new instrument, the Bereaved Parent Needs Assessment–PICU, for assessing parents’ needs in this setting. Using a qualitative approach, our team previously explored how the culture and related ways of providing care in one urban Midwestern children’s hospital PICU affected parents’ bereavement needs and experiences. We describe using this qualitative foundation in the development of a new quantitative instrument to more widely validate and measure bereaved parents’ needs around the time of a child’s death across multiple PICUs. We highlight a series of issues that warrant consideration in designing a research instrument for this vulnerable population including setting and context, format and content, temporality, recruitment, and content expertise.

Design and Methods: The study used data collected from 2993 men through a cross sectional survey in the 2014 Health in Equal Terms survey. Descriptive and logistic regression analyses were carried out to study the relationship between fear of crime and self-reported health and stress. Results: There was a statistically significant association between fear of crime and self-reported poor health and stress among men residing in Gävleborg County. In the bivariate analysis, men who reported fear of crime had odds of 1.98 (CI 1.47- 2.66 and 2.23 (CI 1.45-3.41 respectively. Adjusting for demographic, social and economic variables in the multivariate analysis only reduced the odds ratio for self-reported poor health to 1.52 (CI 1.05-2.21 but not for self-reported stress with odds of 2.22 (1.27-3.86. Conclusions: Fear of crime among men was statistically significantly associated with self-reported poor health and stress in Gävleborg County. However, the statistically significant relationship remained even after accounting for demographic, social and economic factors, which warrants further research to better understand the role played by other variables.

Principles relating to the digital instrumentation and control design approach 2017

International Nuclear Information System (INIS)

2017-01-01

The design of the instrumentation and control of nuclear facilities uses digital systems that offer increasing computation and interconnection capabilities. They enable advanced functions to be carried out, such as calculation of the critical heat flux ratio, help to detect hardware failures in real time and provide operators with rich, flexible interfaces. However, these evolved functions may be affected by faults that make their logic systematically inadequate in certain cases, which introduces sources of failure other than random hardware failures and raises questions about the informal concept of the increased 'complexity' of instrumentation and control. Appropriate design principles shall therefore be applied so that this logic is as fault-free as possible and can be assessed by an independent body such as IRSN. This document presents the main problems associated with the design of the digital instrumentation and control of a complex facility, as well as the general principles to follow to demonstrate that a satisfactory safety level has been achieved. The doctrine elements presented in this document are the result of the experience acquired during assessments carried out for the French nuclear power plants, enhanced by exchanges with experts from the nuclear sector, and reflect French practice; they apply in other sectors in which a high level of confidence can be attributed to instrumentation and control. The normative texts cited in this document provide detailed requirements that are open to considerable interpretation, as the nature of the problem posed does not enable relevant and measurable criteria to be defined in all cases. This document aims to explain the principles underlying these detailed requirements and to give the means for interpreting them in each situation. (authors)

Phillips, Samantha; Sen, Dil; McNamee, Roseanne

2007-08-01

Work-related stress (WRS) is the leading cause of occupational ill-health in the education sector in the UK. Headship is believed to be a stressful role although there is little current research into stress in head teachers. Changes in the education sector since the late 1980s have meant that the findings of many existing studies are outdated. To investigate prevalence and causes of self-reported, WRS in head teachers in West Sussex, UK. A cross-sectional study using postal questionnaire in a population of 290 head teachers and principals. The measuring instrument was a short stress evaluation tool (ASSET) plus additional questions derived from previous studies. Stress cases were defined as respondents who felt their work was 'very or extremely stressful'. Prevalence of self-reported, WRS was 43%. Using ASSET scoring, work overload and work-life imbalance were the key stressors. Females were significantly more stressed than males for a number of stressors including overload and control. Although there was some evidence that primary head teachers fared worse than their secondary counterparts, once the confounding effects of gender were included, there were few significant differences. The prevalence of self-reported stress in head teachers in West Sussex is significantly increased compared to recent studies of workers in the UK. The recurring theme in existing studies of workload as a main stressor is confirmed in the findings of this study. Gender and type of school does affect outcome and female head teachers have more reported stressors than their male colleagues.

Thermal design and performance of the REgolith x-ray imaging spectrometer (REXIS) instrument

Stout, Kevin D.; Masterson, Rebecca A.

2014-08-01

The REgolith X-ray Imaging Spectrometer (REXIS) instrument is a student collaboration instrument on the OSIRIS-REx asteroid sample return mission scheduled for launch in September 2016. The REXIS science mission is to characterize the elemental abundances of the asteroid Bennu on a global scale and to search for regions of enhanced elemental abundance. The thermal design of the REXIS instrument is challenging due to both the science requirements and the thermal environment in which it will operate. The REXIS instrument consists of two assemblies: the spectrometer and the solar X-ray monitor (SXM). The spectrometer houses a 2x2 array of back illuminated CCDs that are protected from the radiation environment by a one-time deployable cover and a collimator assembly with coded aperture mask. Cooling the CCDs during operation is the driving thermal design challenge on the spectrometer. The CCDs operate in the vicinity of the electronics box, but a 130 °C thermal gradient is required between the two components to cool the CCDs to -60 °C in order to reduce noise and obtain science data. This large thermal gradient is achieved passively through the use of a copper thermal strap, a large radiator facing deep space, and a two-stage thermal isolation layer between the electronics box and the DAM. The SXM is mechanically mounted to the sun-facing side of the spacecraft separately from the spectrometer and characterizes the highly variable solar X-ray spectrum to properly interpret the data from the asteroid. The driving thermal design challenge on the SXM is cooling the silicon drift detector (SDD) to below -30 °C when operating. A two-stage thermoelectric cooler (TEC) is located directly beneath the detector to provide active cooling, and spacecraft MLI blankets cover all of the SXM except the detector aperture to radiatively decouple the SXM from the flight thermal environment. This paper describes the REXIS thermal system requirements, thermal design, and analyses, with

Validation of Self-Reported Cognitive Problems with Objective ...

Science.gov (United States)

There is a lack of validation of self-reported cognitive problems with objective neuropsychological measures. The validity of four self-reported cognitive items from a health questionnaire (HQ) and the Symptoms Checklist 90-Revised (SCL-90-R) was examined with objective clinical neuropsychological test performance in 147 manganese (Mn) exposed residents. These residents were from two Ohio towns exposed to ambient air-Mn from an industrial source with modeled average air-Mn concentrations of 0.54 µg/m3 (range: 0.01-4.58) and were part of a larger study of cognitive, motor, tremor abnormalities and their relationship to Mn exposure.The primarily white (94.6%) participants (aged 30-64) lived in the towns for at least 10 years (range: 10-64) and had 13.9 years of education, on average. In the last 7 days before testing, 94 (64.4%) participants self-reported concentration problems and 105 (71.8%) self-reported memory problems. After adjusting for age and education, participants who self-reported cognitive problems did not perform worse on the objective neuropsychological measures than those who reported not having problems, except on 1 of 17 neuropsychological tests (Stroop Color). Greater levels of depression and female sex predicted having more self-reported cognitive problems. Higher education was associated with fewer self-reported cognitive problems. Measures of Mn in air, blood, hair, and toenails were not associated with subjective cognitive self-reported p

Aim To measure the prevalence of self-reported morbidity and its associated factors among adults (aged ⩾15 years) in a select rural Indian population. Self-reporting of smoking has been validated as population-based surveys using self-reported data provide reasonably consistent estimates of smoking prevalence, and are generally considered to be sufficiently accurate for tracking the general pattern of morbidity associated with tobacco use in populations. However, to gauge the true disease burden using self-reported morbidity data requires cautious interpretation. During 2010-2011, a cross-sectional survey was conducted under the banner of the Health and Demographic Surveillance System, Birbhum, an initiative of the Department of Health and Family Welfare, Government of West Bengal, India. With over 93.6% response rate from the population living in 12 300 households, this study uses the responses from 16 354 individuals: 8012 smokers, and 8333 smokeless tobacco users. Smokers and smokeless tobacco users were asked whether they have developed any morbidity symptoms due to smoking, or smokeless tobacco use. Bivariate, as well as multivariate logistic regression analyses were deployed to attain the study objective. Findings Over 20% of smokers and over 9% of smokeless tobacco users reported any morbidity. Odds ratio (OR) with 95% confidence interval (CI) estimated using logistic regression shows that women are less likely to report any morbidity attributable to smoking (OR: 0.69; CI: 0.54-0.87), and more likely to report any morbidity due to smokeless tobacco use (OR: 1.68; CI: 1.36-2.09). Non-Hindus have higher odds, whereas the wealthiest respondents have lower odds of reporting any morbidity. With a culturally appropriate intervention to change behaviour, youth (both men and women) could be targeted with comprehensive tobacco cessation assistance programmes. A focussed intervention could be designed for unprocessed tobacco users to curb hazardous effects of

Full Text Available Abstract Background Spatial configurations of office environments assessed by Space Syntax methodologies are related to employee movement patterns. These methods require analysis of floors plans which are not readily available in large population-based studies or otherwise unavailable. Therefore a self-report instrument to assess spatial configurations of office environments using four scales was developed. Methods The scales are: local connectivity (16 items, overall connectivity (11 items, visibility of co-workers (10 items, and proximity of co-workers (5 items. A panel cohort (N = 1154 completed an online survey, only data from individuals employed in office-based occupations (n = 307 were used to assess scale measurement properties. To assess test-retest reliability a separate sample of 37 office-based workers completed the survey on two occasions 7.7 (±3.2 days apart. Redundant scale items were eliminated using factor analysis; Chronbach’s α was used to evaluate internal consistency and test re-test reliability (retest-ICC. ANOVA was employed to examine differences between office types (Private, Shared, Open as a measure of construct validity. Generalized Linear Models were used to examine relationships between spatial configuration scales and the duration of and frequency of breaks in occupational sitting. Results The number of items on all scales were reduced, Chronbach’s α and ICCs indicated good scale internal consistency and test re-test reliability: local connectivity (5 items; α = 0.70; retest-ICC = 0.84, overall connectivity (6 items; α = 0.86; retest-ICC = 0.87, visibility of co-workers (4 items; α = 0.78; retest-ICC = 0.86, and proximity of co-workers (3 items; α = 0.85; retest-ICC = 0.70. Significant (p ≤ 0.001 differences, in theoretically expected directions, were observed for all scales between office types, except overall connectivity. Significant associations were

Full Text Available The construct “self” appears in diverse forms in theories about what it is to be a person. As the sense of “self” is typically assessed through personal reports, differences in its description undoubtedly reflect significant differences in peoples’ apperception of self. This report describes the development, reliability, and factorial structure of the Experience of Sense of Self (E-SOS, an inventory designed to assess one’s perception of self in relation to the person’s perception of various potential “others.” It does so using Venn diagrams to depict and quantify the experienced overlap between the self and “others.” Participant responses to the instrument were studied through Exploratory Factor Analysis. This yielded a five-factor solution: 1 Experience of Positive Sensation; 2 Experience of Challenges; 3 Experience of Temptations; 4 Experience of Higher Power; and 5 Experience of Family. The items comprising each of these were found to produce reliable subscales. Further research with the E-SOS and suggestions for its use are offered.

2012-10-01

Can we assess individual differences in the extent to which a person perceives the rubber-hand illusion on the basis of self-reported experiences? In this research, we develop such an instrument using Rasch-type models. In our conception, incorporating an object (e.g., a rubber hand) into one's body image requires various sensorimotor and cognitive processes. The extent to which people can meet these requirements thus determines how intensely people experience and, simultaneously, describe the illusion. As a consequence, individual differences in people's susceptibility to the rubber-hand illusion can be determined by inspecting reports of their personal experiences. The proposed model turned out to be functional in its capability to predict self-reports of people's experiences and to reliably assess individual differences in susceptibility to the illusion. Regarding validity, we found a small, but significant, correlation between individual susceptibility and proprioceptive drift. Additionally, we found that asynchrony, and tapping rather than stroking the fingers constrain the experience of the illusion. Copyright © 2012 Elsevier B.V. All rights reserved.

2018-03-01

Up until now, empirical studies in the Student Approaches to Learning field have mainly been focused on the use of self-report instruments, such as interviews and questionnaires, to uncover differences in students' general preferences towards learning strategies, but have focused less on the use of task-specific and online measures. This study aimed at extending current research on students' learning strategies by combining general and task-specific measurements of students' learning strategies using both offline and online measures. We want to clarify how students process learning contents and to what extent this is related to their self-report of learning strategies. Twenty students with different generic learning profiles (according to self-report questionnaires) read an expository text, while their eye movements were registered to answer questions on the content afterwards. Eye-tracking data were analysed with generalized linear mixed-effects models. The results indicate that students with an all-high profile, combining both deep and surface learning strategies, spend more time on rereading the text than students with an all-low profile, scoring low on both learning strategies. This study showed that we can use eye-tracking to distinguish very strategic students, characterized using cognitive processing and regulation strategies, from low strategic students, characterized by a lack of cognitive and regulation strategies. These students processed the expository text according to how they self-reported. © 2017 The British Psychological Society.

This paper presents a safety reporting smartphone application which is expected to reduce the occurrence of postoperative adverse events after total hip arthroplasty (THA). A user-centered design approach was utilized to facilitate optimal user experience. Two main implemented functionalities capture patient pain levels and well-being, the two dimensions of patient status that are intuitive and commonly checked. For these and other functionalities, mobile technology could enable timely safety reporting and collection of patient data out of a hospital setting. The HCI expert, and healthcare professionals from the Haukeland University Hospital in Bergen have assessed the design with respect to the interaction flow, information content, and self-reporting functionalities. They have found it to be practical, intuitive, sufficient and simple for users. Patient self-reporting could help recognizing safety issues and adverse events.

Full Text Available Although the application of patient-specific instruments (PSI for total knee arthroplasty (TKA increases the cost of the surgical procedure, PSI may reduce operative time and improve implant alignment, which could reduce the number of revision surgeries. We report our experience with TKA using PSI techniques in 120 patients from March to December 2014. PSI for TKA were created from data provided by computed tomography (CT scans or magnetic resonance imaging (MRI; which imaging technology is more reliable for the PSI technique remains unclear. In the first 20 patients, the accuracy of bone resection and PSI stability were compared between CT and MRI scans with presurgical results as a reference; MRI produced better results. In the second and third groups, each with 50 patients, the results of bone resection and stability were compared in MRI scans with respect to the quality of scanning due to motion artifacts and experienced know-how in PSI design, respectively. The optimized femoral cutting guide design for PSI showed the closest outcomes in bone resection and PSI stability with presurgical data. It is expected that this design could be a reasonable guideline in PSI.

de Knegt, Nanda C; Lobbezoo, Frank; Schuengel, Carlo; Evenhuis, Heleen M; Scherder, Erik J A

2016-01-01

The use of the Self-reporting Tool On Pain in people with Intellectual Disabilities (STOP-ID!), an online application developed by the authors to aid in the self-reporting of pain, was evaluated in 40 adults with Down syndrome. Comprehension of the use of the tool (the ability to recognize representations for vocabulary and pain, and to navigate the tool interface), and the use of the tool to self-report pain experience, were investigated. The use of the online tool was investigated with both a laptop and a tablet computer in a crossover design. The results provide evidence that more participants recognized representations of pain location and pain affect than representations of pain intensity and pain quality. A small percentage of participants demonstrated the ability to recognize all of the representations of vocabulary items and to navigate the tool without assistance (18% laptop, 18% tablet). Half of the participants were able to report at least one pain component of a current or remembered pain experience without assistance (50% laptop, 53% tablet). Ways to improve the design of tools for reporting pain and to improve performance are suggested.

Evaluation of the Self-Adjusting File system (SAF) for the instrumentation of primary molar root canals: a micro-computed tomographic study.

Kaya, E; Elbay, M; Yiğit, D

2017-06-01

The Self-Adjusting File (SAF) system has been recommended for use in permanent teeth since it offers more conservative and effective root-canal preparation when compared to traditional rotary systems. However, no study had evaluated the usage of SAF in primary teeth. The aim of this study was to evaluate and compare the use of SAF, K file (manual instrumentation) and Profile (traditional rotary instrumentation) systems for primary-tooth root-canal preparation in terms of instrumentation time and amounts of dentin removed using micro-computed tomography (μCT) technology. Study Design: The study was conducted with 60 human primary mandibular second molar teeth divided into 3 groups according to instrumentation technique: Group I: SAF (n=20); Group II: K file (n=20); Group III; Profile (n=20). Teeth were embedded in acrylic blocks and scanned with a μCT scanner prior to instrumentation. All distal root canals were prepared up to size 30 for K file,.04/30 for Profile and 2 mm thickness, size 25 for SAF; instrumentation time was recorded for each tooth, and a second μCT scan was performed after instrumentation was complete. Amounts of dentin removed were measured using the three-dimensional images by calculating the difference in root-canal volume before and after preparation. Data was statistically analysed using the Kolmogorov-Smirnov and Kruskal-Wallis tests. Manual instrumentation (K file) resulted in significantly more dentin removal when compared to rotary instrumentation (Profile and SAF), while the SAF system generated significantly less dentin removal than both manual instrumentation (K file) and traditional rotary instrumentation (Profile) (psystems. Within the experimental conditions of the present study, the SAF seems as a useful system for root-canal instrumentation in primary molars because it removed less dentin than other systems, which is especially important for the relatively thin-walled canals of primary teeth, and because it involves less

Small-scale intellectualized medical instrument has attracted great attention in the field of biomedical engineering, and LabVIEW (Laboratory Virtual Instrument Engineering Workbench) provides a convenient environment for this application due to its inherent advantages. The principle and system structure of the hyperthermia instrument are presented. Type T thermocouples are employed as thermotransducers, whose amplifier consists of two stages, providing built-in ice point compensation and thus improving work stability over temperature. Control signals produced by specially designed circuit drive the programmable counter/timer 8254 chip to generate PWM (Pulse width modulation) wave, which is used as ultrasound radiation energy control signal. Subroutine design topics such as inner-tissue real time feedback temperature control algorithm, water temperature control in the ultrasound applicator are also described. In the cancer tissue temperature control subroutine, the authors exert new improvments to PID (Proportional Integral Differential) algorithm according to the specific demands of the system and achieve strict temperature control to the target tissue region. The system design and PID algorithm improvement have experimentally proved to be reliable and excellent, meeting the requirements of the hyperthermia system.

Such 'top down' approaches are common, but the explicit pre-validation methods are often poorly reported. This paper presents a systematic and generalisable 5-step pre-validation PRO instrument methodology. Methods The method is illustrated using the example of the Aberdeen Glaucoma Questionnaire (AGQ. The five steps are: 1 Generation of a pool of items; 2 Item de-duplication (three phases; 3 Item reduction (two phases; 4 Assessment of the remaining items' content coverage against a pre-existing theoretical framework appropriate to the objectives of the instrument and the target population (e.g. ICF; and 5 qualitative exploration of the target populations' views of the new instrument and the items it contains. Results The AGQ 'item pool' contained 725 items. Three de-duplication phases resulted in reduction of 91, 225 and 48 items respectively. The item reduction phases discarded 70 items and 208 items respectively. The draft AGQ contained 83 items with good content coverage. The qualitative exploration ('think aloud' study resulted in removal of a further 15 items and refinement to the wording of others. The resultant draft AGQ contained 68 items. Conclusions This study presents a novel methodology for developing a PRO instrument, based on three sources: literature reporting what is important to patient; theoretically coherent framework; and patients' experience of completing the instrument. By systematically accounting for all items dropped

Naturalistic driving methods require the installation of instruments and cameras in vehicles to record driving behavior. A critical, yet unexamined issue in naturalistic driving research is the extent to which the vehicle instruments and cameras used for naturalistic methods change human behavior. We sought to describe the degree to which teenage participants' self-reported awareness of vehicle instrumentation changes over time, and whether that awareness was associated with driving behaviors. Forty-two newly-licensed teenage drivers participated in an 18-month naturalistic driving study. Data on driving behaviors including crash/near-crashes and elevated gravitational force (g-force) events rates were collected over the study period. At the end of the study, participants were asked to rate the extent to which they were aware of instruments in the vehicle at four time points. They were also asked to describe their own and their passengers' perceptions of the instrumentation in the vehicle during an in-depth interview. The number of critical event button presses was used as a secondary measure of camera awareness. The association between self-reported awareness of the instrumentation and objectively measured driving behaviors was tested using correlations and linear mixed models. Most participants' reported that their awareness of vehicle instrumentation declined across the duration of the 18-month study. Their awareness increased in response to their passengers' concerns about the cameras or if they were involved in a crash. The number of the critical event button presses was initially high and declined rapidly. There was no correlation between driver's awareness of instrumentation and their crash and near-crash rate or elevated g-force events rate. Awareness was not associated with crash and near-crash rates or elevated g-force event rates, consistent with having no effect on this measure of driving performance. Naturalistic driving studies are likely to yield

Managing chronic conditions can be challenging. People in such conditions, and the people around them, have to: deal with symptoms, adapt to the resulting disability, manage emotions, and change habits to keep the condition under control. Self-care technologies have the potential to support self-care...... and mediate the relationship between patients (and caregivers) and the condition. However, these technologies often disregard the complexity of the settings in which they are used and fail to become integrated in everyday life. In this workshop we will discuss how to design self-care technologies...

A study of the modifications of nuclear instrumentation systems for JRR-2

In this report a comparative study has been carried out between the original A.M.F. design and the modified design for the nuclear instrumentation systems of the Research Reactor JRR-2, at the Tokai Research Establishment of JAERI. Due to a fire accident in the control room, in July 1968, the originally designed nuclear instrumentation systems, using conventional vacuum tube circuits, were destroyed and were replaced by the modified design, incorporating solid state linear integrated circuits as basic circuit components. The results of the reactor instrumentation systems modification at JRR-2 are very encouraging as the operating efficiency of the Reactor registered an improvement of 43%. Moreover the safety aspects have been fully taken care of in the new design and the reactor is well guarded against all possible instrument failures and human errors. This report presents the basic theory of operation of the two designs alongwith a comparative safety analysis. (auth.)

We examined whether US adults who reported increasing their physical activity to control or lower blood cholesterol following physician’s advice or on their own efforts had higher levels of physical activity than those who reported that they did not. We used data from the National Health and Nutrition Examination Survey 2003–2004, which implemented two physical activity assessment instruments. The physical activity questionnaire (PAQ assessed self-reported frequency, intensity, and duration of leisure-time, household, and transportation-related physical activity in the past month. Physical movement was objectively monitored using a waist accelerometer that assessed minute-by-minute intensity (counts of movement/minute during waking time over a 7-day period. We adjusted our analysis for age, gender, race/ethnicity, educational attainment, and body mass index. Participants who reported increasing physical activity to control blood cholesterol had more PAQ-assessed physical activity and more accelerometer-assessed active days per week compared to those who did not. However, there were no significant differences in cholesterol levels between comparison groups. These findings suggest that self-report of exercising

IBEX-Hi is an electrostatic analyzer spacecraft instrument designed to measure the energy and flux distribution of energetic neutral atoms (ENAs) emanating from the interaction zone between the Earth's solar system and the Milky Way galaxy. A key element to this electro-optic instrument is an array of fourteen carbon foils that are used to ionize the ENAs. The foils are comprised of an ultrathin (50-100 {angstrom} thick) layer of carbon suspended across the surface of an electroformed Nickel wire screen, which in turn is held taught by a metal frame holder. The electro formed orthogonal screen has square wire elements, 12.7 {micro}m thick, with a pitch of 131.1 wires/cm. Each foil holder has an open aperture approximately 5 cm by 2.5 cm. Designing and implementing foil holders with such a large surface area has not been attempted for spaceflight in the past and has proven to be extremely challenging. The delicate carbon foils are subject to fatigue failure from the large acoustic and vibration loads that they will be exposed to during launch of the spacecraft. This paper describes the evolution of the foil holder design from previous space instrument applications to a flight-like IBEX-Hi prototype. Vibro-acoustic qualification tests of the IBEX-Hi prototype instrument and the resulting failure of several foils are summarized. This is followed by a discussion of iterative foil holder design modifications and laser vibrometer modal testing to support future fatigue failure analyses, along with additional acoustic testing of the IBEX-Hi prototype instrument. The results of these design and testing activities are merged and the resulting flight-like foil holder assembly is proposed.

As part of the Kumamoto RAINBOW Project, a multifaceted implementation of the prevention of premature labor, we investigated pregnant women's oral health status and assessed the validity of a self-reported periodontal disease questionnaire. We examined the oral health status of pregnant women and asked them for subjective descriptions of symptoms of periodontitis both in the first and the second half of their pregnancy in Kumamoto Prefecture from August 2012 to January 2014. The Community Periodontal Index (CPI) was used to assess the periodontal condition, and women having periodontal pockets with depths of ≥4 mm were catecogorized as having periodontitis. The results were the scores of the self-questionnaire for periodontal disease prepared by the Japan Dental Association. Of the 9,527 pregnant women who received periodontal check- ups during the first half of pregnancy, 32 percent were diagnosed as having periodontitis. The self-questionnaire had a sensitivity of 51.2% and a specificity of 62.9% for pregnant women to predict their periodontal disease. Then, we evaluated the importance of each question by logistic regression analysis and extracted the useful items. An increased sensitivity (79.9%) was obtained with the best of the modified questionnaire. To our knowledge, this is the first report of the evaluation of the usefulness of the self-reported periodontal disease questionnaire for pregnant women. The current self-questonnaire used for the general adult population was less sensitive for pregnant women. Our modified questionnaire showed an improved sensitivity for diagnosing periodontitis, but its specificity remained low. A specialized self-questionnaire for periodontal disease in pregnant women should be designed.
