    Continuous quality improvement (CQI) activities depend on valid and reliable instruments to generate data. An evaluation of internal and external customer satisfaction is one of the pillars of the CQI process. This article describes the development of a valid and reliable instrument for measuring physicians' satisfaction with the orthopedic nursing units at a major medical trauma center. The physician satisfaction survey instrument was found to be internally consistent (alpha = .95). Confirmatory factor analysis revealed that 68% of the variance in physician satisfaction scores (eigenvalue = 8.14) was explained by using a single-factor model.

    The development of a self-report instrument to measure antisocial sport behavior, labeled the Antisocial Sport Behavior Survey (ASBS), among large and diverse samples of athletes is reported. Grounded in the social cognitive theory of moral thought and action (Bandura, 1991) and interpersonal theory (Horowitz, 2004), this instrument was developed and tested in accordance with the traditions of construct validity and classical test theory (Gehlback & Brinkworth, 2011). In Phase 1, 272 college-aged competitive sport participants confirmed a theoretical structure of antisocial sport behavior including eight factors (hypercompetitive, intimidating, antagonistic, disrespectful, exploitable, overly accommodating, abetting, and melodramatic). Phase 2 reports on item development and the response structure of the instrument. In Phase 3, evidence of structural validity and external validity for the ASBS was established with 340 college-aged competitive sport participants. The ASBS presents as a promising new instrument to advance understanding of antisocial sport behavior acts committed by competitive athletes.

    Full Text Available An examination of the psychometric properties of the Lateral Violence in Nursing Survey (LVNS, an instrument previously developed to measure the perceived incidence and severity of lateral violence (LV in the nursing workplace, was carried out. Conceptual clustering and principal components analysis were used with survey responses from 663 registered nurses and ancillary nursing staff in a southeastern tertiary care medical center. Where appropriate, Cronbach’s alpha (α evaluated internal consistency. The prevalence/severity of lateral violence items constitute two distinct subscales (LV by self and others with Cronbach’s alpha of 0.74 and 0.86, respectively. The items asking about potential causes of LV are unidimensional and internally consistent (alpha = 0.77 but there is no conceptually coherent theme underlying the various causes. Respondents rating a potential LV cause as “major” scored higher on both prevalence/severity subscales than those rating it a “minor” cause or not a cause. Subsets of items on the LVNS are internally reliable, supporting construct validity. Revisions of the original LVNS instrument will improve its use in future work.

    This paper is a report of a study to explore Australian parents' knowledge, beliefs, practices and information sources about fever management and develop a scale to measure parents' fever management practices. Parental fever phobia and overuse of antipyretics to reduce fever continue. No scales to measure parents' fever management practices are available. A community-based, postal survey was carried out in 2005 with 401 Australian parents of well children aged 6 months-5 years. Respondents were recruited through advertising (48.4%), face-to-face (26.4%) and snowball (24.4%) methods. A 33-item instrument was developed; construct and content validity were determined by an expert panel and item reliability by test-retest. Moderate fever (40.0 +/- 1.0 degrees C) was reported to be harmful (88%), causing febrile convulsions (77.7%). Usual practices targeted temperature reduction, antipyretic administration (87.8%), temperature monitoring (52.5%). Fewer evidence-based practices, such as encouraging fluids (49.0%) and light clothing (43.8%), were reported. Positive changes over time (36.4%) included less concern and delayed or reduced antipyretic use. Negative practice changes (22.7%) included greater concern and increased antipyretic use. Medical advice was sought for illness symptoms (48.7%) and high (37.4%) or persistent (41.5%) fevers. Fever management was learnt from doctors, family and friends and working experience, while receiving conflicting information (41.9%) increased concerns and created uncertainty about best practice. Parents need consistent evidence-based information about childhood fever management. The Parental Fever Management Scale requires further testing with different populations and in different cultures and healthcare systems to evaluate its usefulness in nursing practice and research.

    To develop a theoretically informed and empirically validated survey instrument for assessing prescribers' perception of computerized drug-drug interaction (DDI) alerts. The survey is grounded in the unified theory of acceptance and use of technology and an adapted accident causation model. Development of the instrument was also informed by a review of the extant literature on prescribers' attitude toward computerized medication safety alerts and common prescriber-provided reasons for overriding. To refine and validate the survey, we conducted a two-stage empirical validation study consisting of a pretest with a panel of domain experts followed by a field test among all eligible prescribers at our institution. The resulting survey instrument contains 28 questionnaire items assessing six theoretical dimensions: performance expectancy, effort expectancy, social influence, facilitating conditions, perceived fatigue, and perceived use behavior. Satisfactory results were obtained from the field validation; however, a few potential issues were also identified. We analyzed these issues accordingly and the results led to the final survey instrument as well as usage recommendations. High override rates of computerized medication safety alerts have been a prevalent problem. They are usually caused by, or manifested in, issues of poor end user acceptance. However, standardized research tools for assessing and understanding end users' perception are currently lacking, which inhibits knowledge accumulation and consequently forgoes improvement opportunities. The survey instrument presented in this paper may help fill this methodological gap. We developed and empirically validated a survey instrument that may be useful for future research on DDI alerts and other types of computerized medication safety alerts more generally.

    The need to measure and evaluate orthotics and prosthetics (O&P) practice has received growing recognition in the past several years. Reliable and valid self-report instruments are needed that can help facilities evaluate patient outcomes. The objective of this project was to develop a set of self-report instruments that assess functional status, quality of life, and satisfaction with devices and services that can be used in an orthotics and prosthetics clinic. Selecting items from a variety of existing instruments, the authors developed and revised four instruments that differentiate patients with varying levels of lower limb function, quality of life, and satisfaction with devices and services. Evidence of construct validity is provided by hierarchies of item difficulty that are consistent with clinical experience. For example, with the lower limb function instrument, running one block was much more difficult than walking indoors. The instruments demonstrate adequate internal consistency (0.88 for lower limb function, 0.88 for quality of life, 0.74 for service satisfaction, 0.78 for device satisfaction). The next steps in their research programme are to evaluate sensitivity and construct validity. The Orthotics and Prosthetics Users' Survey (OPUS) is a promising self-report instrument which may, with further development, allow orthotic and prosthetic practitioners to evaluate the quality and effectiveness of their services as required by accreditation standards such as those of the American Board for Certification in Orthotics and Prosthetics that mandate quality assessment.

    Full Text Available Global trade and the abolition of trade barriers lead to the proliferation of imported food products such as various types of fast food products (RTE: ready-to-eat food sold by convenience stores mainly scattered in Jakarta. The question is what causes consumers choose certain convenience store to buy RTE Product and not choose another outlet category. To understand consumer perceptions, it is necessary to develop an instrument for measuring consumer perceptions of the option to purchase RTE Product at convenience stores. Variables used in this research are the perception and knowledge of the public/consumers against food safety, store attributes, service, and product attributes. The instrument used in this study is a questionnaire with a scalemeasuring1-5 to see the relationship between variables, we used the method of Structural Equation Modeling (SEM. The sample used in this study was 223 respondents that were divided into five areas in Jakarta, namely Central Jakarta, West Jakarta, South Jakarta, East Jakarta, and North Jakarta. The final outcome of the instrument development process was 25 observed variables, consisting of 4 indicators, which valid and reliable, with T-values for each observed variable is above 2,58, and Construct Reliability values range between 0,76 to 0,853.

    Information systems (IS) benefits for nurses are outcomes related to the tangible products or improvements that nurses realize from using IS. This study examined the development and psychometric testing of a measure of nurses' benefits from IS. A random sample of 570 nurses working in hospitals, providing direct patient care, and using IS completed the study questionnaire. The internal consistency reliability of the results was .97. Exploratory factor analysis, using principal components extraction and varimax rotation, revealed items loaded on four factors (saving time and efficiency, quality of care, charting, and professional practice) that were confirmed by confirmatory factor analysis. Continued refinement of the instrument is needed with more diverse samples of nurses.

    Coalitions are often composed of member organizations. Member involvement is thought to be associated with coalition success. No instrument currently exists for evaluating organizational member involvement in physical activity coalitions. This study aimed to develop a survey instrument for evaluating organizational member involvement in physical activity coalitions. The study was carried out in three phases: (a) developing a draft survey, (b) assessing the content validity of the draft survey, and (c) assessing the underlying factor structure, reliability, and validity of the survey. A cross-sectional design was employed. In Phase 1, a team of experts in survey development produced a draft survey. In Phase 2, the content validity of the draft survey was evaluated by a panel of individuals with expertise in physical activity coalitions. In Phase 3, the survey was administered to 120 individuals on local-, state-, and national-level physical activity coalitions. Responses were subjected to an exploratory factor analysis in order to determine the survey's underlying factor structure, reliability, and validity. Phases 1 and 2yielded a survey instrument with demonstrated content validity. Phase 3 yielded a three-factor model with three subscales: Strategic Alignment, Organizational Alignment, and Providing Input. Each subscale demonstrated high internal consistency reliability and construct validity. The survey instrument developed here demonstrated sound psychometric properties and provides new insight into organizational member involvement in physical activity coalitions. This instrument may be an important tool in developing a more complete picture of coalition functioning in physical activity coalitions specifically and health-based coalitions overall. © 2014 Society for Public Health Education.

    Many developed countries are improving or operating the advanced I and C systems of NPPs. They are: (1) N4 of EDF in France, (2) AP 600 of Westinghouse in USA, (3) NUPLEX-80+ of ABB-CE in USA, (4) CANDU in Canada, (5) Ohi 3 and 4, APWR and ABWR in Japan, (6) Belt-D in Germany, (7) Sizewell B in Britain, (8) Halden Reactor Projector in Norway, (9) I and C systems in Russia and Eastern Europe. This report describes the development trend, background, system architecture, characteristics with the new safety concerns, licensing problems, future plan, and retrofit experiences of these advanced nuclear I and C systems. The biggest difference between the existing systems and the advanced systems is the application of software rather than hardware for the functional implementation. All of the improved I and C systems accepted the standard modules and off-the shelf devices. Their characteristics are focused on EPRI URD Chapter 10. (author).

    Eliza L Y Wong

    Full Text Available Patient experience reflects quality of care from the patients' perspective; therefore, patients' experiences are important data in the evaluation of the quality of health services. The development of an abbreviated, reliable and valid instrument for measuring inpatients' experience would reflect the key aspect of inpatient care from patients' perspective as well as facilitate quality improvement by cultivating patient engagement and allow the trends in patient satisfaction and experience to be measured regularly. The study developed a short-form inpatient instrument and tested its ability to capture a core set of inpatients' experiences. The Hong Kong Inpatient Experience Questionnaire (HKIEQ was established in 2010; it is an adaptation of the General Inpatient Questionnaire of the Care Quality Commission created by the Picker Institute in United Kingdom. This study used a consensus conference and a cross-sectional validation survey to create and validate a short-form of the Hong Kong Inpatient Experience Questionnaire (SF-HKIEQ. The short-form, the SF-HKIEQ, consisted of 18 items derived from the HKIEQ. The 18 items mainly covered relational aspects of care under four dimensions of the patient's journey: hospital staff, patient care and treatment, information on leaving the hospital, and overall impression. The SF-HKIEQ had a high degree of face validity, construct validity and internal reliability. The validated SF-HKIEQ reflects the relevant core aspects of inpatients' experience in a hospital setting. It provides a quick reference tool for quality improvement purposes and a platform that allows both healthcare staff and patients to monitor the quality of hospital care over time.

    2011-01-01

    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.

    Petrie, G.

    The situation regarding photogrammetric instrumentation has changed quite dramatically over the last 2 or 3 years with the withdrawal of most analogue stereo-plotting machines from the market place and their replacement by analytically based instrumentation. While there have been few new developments in the field of comparators, there has been an explosive development in the area of small, relatively inexpensive analytical stereo-plotters based on the use of microcomputers. In particular, a number of new instruments have been introduced by manufacturers who mostly have not been associated previously with photogrammetry. Several innovative concepts have been introduced in these small but capable instruments, many of which are aimed at specialised applications, e.g. in close-range photogrammetry (using small-format cameras); for thematic mapping (by organisations engaged in environmental monitoring or resources exploitation); for map revision, etc. Another innovative and possibly significant development has been the production of conversion kits to convert suitable analogue stereo-plotting machines such as the Topocart, PG-2 and B-8 into fully fledged analytical plotters. The larger and more sophisticated analytical stereo-plotters are mostly being produced by the traditional mainstream photogrammetric systems suppliers with several new instruments and developments being introduced at the top end of the market. These include the use of enlarged photo stages to handle images up to 25 × 50 cm format; the complete integration of graphics workstations into the analytical plotter design; the introduction of graphics superimposition and stereo-superimposition; the addition of correlators for the automatic measurement of height, etc. The software associated with this new analytical instrumentation is now undergoing extensive re-development with the need to supply photogrammetric data as input to the more sophisticated G.I.S. systems now being installed by clients, instead

    Full Text Available Background Clinical data are collected for routine care in family practice; there are also a growing number of genetic and cancer registry data repositories. The Translational Research and Patient Safety in Europe (TRANSFoRm project seeks to facilitate research using linked data from more than one source. We performed a requirements analysis which identified a wide range of data and business process requirements that need to be met before linking primary care and either genetic or disease registry data.Objectives To develop a survey to assess the readiness of data repositories to participate in linked research – the Transform International Research Readiness (TIRRE survey.Method We develop the questionnaire based on our requirement analysis; with questions at micro-, meso- and macro levels of granularity, study-specific questions about diabetes and gastro-oesophageal reflux disease (GORD, and research track record. The scope of the data required was extensive. We piloted this instrument, conducting ten preliminary telephone interviews to evaluate the response to the questionnaire.Results Using feedback gained from these interviews we revised the questionnaire; clarifying questions that were difficult to answer and utilising skip logic to create different series of questions for the various types of data repository. We simplified the questionnaire replacing free-text responses with yes/no or picking list options, wherever possible. We placed the final questionnaire online and encouraged its use (www.clininf.eu/jointirre/info.html.Conclusion Limited field testing suggests that TIRRE is capable of collecting comprehensive and relevant data about the suitability and readiness of data repositories to participate in linked data research.

    Full Text Available Objectives: The goal of this project was to develop the first disease-specific instrument for the evaluation of quality of life in chronic pancreatitis. Methods: Focus groups and interview sessions were conducted, with chronic pancreatitis patients, to identify items felt to impact quality of life which were subsequently formatted into a paper-and-pencil instrument. This instrument was used to conduct an online survey by an expert panel of pancreatologists to evaluate its content validity. Finally, the modified instrument was presented to patients during precognitive testing interviews to evaluate its clarity and appropriateness. Results: In total, 10 patients were enrolled in the focus groups and interview sessions where they identified 50 items. Once redundant items were removed, the 40 remaining items were made into a paper-and-pencil instrument referred to as the Pancreatitis Quality of Life Instrument. Through the processes of content validation and precognitive testing, the number of items in the instrument was reduced to 24. Conclusions: This marks the development of the first disease-specific instrument to evaluate quality of life in chronic pancreatitis. It includes unique features not found in generic instruments (economic factors, stigma, and spiritual factors. Although this marks a giant step forward, psychometric evaluation is still needed prior to its clinical use.

    Although we know a great deal about the percentage of youth who drink alcohol, we know very little about the specific brands they choose to drink. This information gap needs to be addressed if public health officials are to develop more effective interventions. Unfortunately, there are no national youth surveys that collect data on alcohol brand consumption. In this paper, we describe the development and pilot testing of what we believe to be the first comprehensive, Internet-based youth survey of brand-specific alcohol use. We used online advertising in 3 U.S. cities to recruit a convenience sample of 241 respondents, ages 16 to 18 years. We used Craigslist, a network of online communities that features local classified advertisements, to recruit the sample. We used SurveyGizmo, an online software program for designing Internet surveys, collecting data, and performing basic analysis, to survey these respondents about their brand-specific alcohol consumption patterns. The survey instrument assessed each respondent's 30-day drinking history, including the frequency of consumption for each alcohol brand. Using Internet survey technology, we were able to collect information on 366 brands and still have respondents complete the instrument quickly and easily. The total number of brands consumed in the past 30 days ranged from 1 to 18, with a median of 4 brands. The top 5 brands consumed were beer brands, as were eleven of the top 15 brands. The remaining 4 brands in the top 15 included 3 brands of flavored alcoholic beverages and 1 brand of mixed drink. Among the top 15 alcohol brands consumed during heavy drinking episodes were 8 brands of beer, 4 brands of flavored alcoholic beverages, 2 brands of wine, and 1 brand of mixed drink. This pilot study helps establish the feasibility of including brand-specific questions on federal or other national youth alcohol surveys. Copyright © 2011 by the Research Society on Alcoholism.

Objective  To identify specific competencies for health in definitions of health literacy and patient‐centred concepts and empirically test their dimensionality in the general population. Methods  A thorough review of the literature on health literacy, self‐management, patient empowerment, patient education and shared decision making revealed considerable conceptual overlap as competencies for health and identified a corpus of 30 generic competencies for health. A questionnaire containing 127 items covering the 30 competencies was fielded as a telephone interview in German, French and Italian among 1255 respondents randomly selected from the resident population in Switzerland. Findings  Analyses with the software MPlus to model items with mixed response categories showed that the items do not load onto a single factor. Multifactorial models with good fit could be erected for each of five dimensions defined a priori and their corresponding competencies: information and knowledge (four competencies, 17 items), general cognitive skills (four competencies, 17 items), social roles (two competencies, seven items), medical management (four competencies, 27 items) and healthy lifestyle (two competencies, six items). Multiple indicators and multiple causes models identified problematic differential item functioning for only six items belonging to two competencies. Conclusions  The psychometric analyses of this instrument support broader conceptualization of health literacy not as a single competence but rather as a package of competencies for health.

    Hohashi's Concentric Sphere Family Environment Model (CSFEM; Hohashi & Honda, 2011) is a newly proposed family nursing theory for holistically understanding the family environment that acts on family well-being. The purpose of this article is to develop and psychometrically test the Japanese version of the Survey of Family Environment (SFE-J), grounded in the CSFEM, for measuring family's perceived family functioning and family's perceived needs for family support. The SFE-J is a 30-item self-administered instrument that assesses five domains (suprasystem, macrosystem, microsystem, family internal environment system, and chronosystem) and has been subjected to rigorous reliability and validity investigations among paired partners in child-rearing families (N of family = 1,990). Internal consistency reliability was high as measured by Cronbach's alpha coefficients. Temporal stability over a 2-week interval was supported by high (substantial or perfect) and significant intraclass correlation coefficients. The total score for the SFE-J was significantly correlated with the Japanese version of the Feetham Family Functioning Survey (FFFS-J), indicating an acceptable concurrent validity. Construct validity was supported by a confirmatory factor analysis that evaluated the five-factor structure to measure the concept of CSFEM. Results also demonstrate that the SFE-J family functioning scores show no significant differences between paired partners. The SFE-J is a reliable and valid instrument to assess not only intrafamily functioning but also interfamily functioning and, by identifying items/domains with high requirements for family support, serves to facilitate the providing of appropriate support to families.

    The next generation of multi-object spectrographs (MOS) will deliver comprehensive surveys of the Galaxy, Magellanic Clouds and nearby dwarfs. These will provide us with the vast samples, spanning the full extent of the Hertzsprung-Russell diagram, that are needed to explore the chemistry, history and dynamics of their host systems. Further ahead, the Extremely Large Telescopes (ELTs) will have sufficient sensitivity and angular resolution to extend stellar spectroscopy well beyond the Local Group, opening-up studies of the chemical evolution of galaxies across a broad range of galaxy types and environments. In this contribution I briefly reflect on current and future studies of stellar populations, and introduce plans for the MOSAIC instrument for the European ELT.

  15. High resolution tomographic instrument development

    1992-08-01

    Our recent work has concentrated on the development of high-resolution PET instrumentation reflecting in part the growing importance of PET in nuclear medicine imaging. We have developed a number of positron imaging instruments and have the distinction that every instrument has been placed in operation and has had an extensive history of application for basic research and clinical study. The present program is a logical continuation of these earlier successes. PCR-I, a single ring positron tomograph was the first demonstration of analog coding using BGO. It employed 4 mm detectors and is currently being used for a wide range of biological studies. These are of immense importance in guiding the direction for future instruments. In particular, PCR-II, a volume sensitive positron tomograph with 3 mm spatial resolution has benefited greatly from the studies using PCR-I. PCR-II is currently in the final stages of assembly and testing and will shortly be placed in operation for imaging phantoms, animals and ultimately humans. Perhaps the most important finding resulting from our previous study is that resolution and sensitivity must be carefully balanced to achieve a practical high resolution system. PCR-II has been designed to have the detection characteristics required to achieve 3 mm resolution in human brain under practical imaging situations. The development of algorithms by the group headed by Dr. Chesler is based on a long history of prior study including his joint work with Drs. Pelc and Reiderer and Stearns. This body of expertise will be applied to the processing of data from PCR-II when it becomes operational.

    1985-01-01

    An inertial guidance system for aerial surveying has been developed under contract to the U.S. Geological Survey. This prototype system, known as the aerial profiling of terrain (APT) system, is designed to determine continuously the positions of points along an aircraft flight path, or the underlying terrain profile, to an accuracy of + or - 0.5 ft (15 cm) vertically and + or - 2 ft (61 cm) horizontally. The system 's objective thus is to accomplish, from a fixed-wing aircraft, what would traditionally be accomplished from ground-based topographic surveys combined with aerial photography and photogrammetry. The two-part strategy for measuring the terrain profile entails: (1) use of an inertial navigator for continuous determination of the three-coordinate position of the aircraft, and (2) use of an eye-safe pulsed laser profiler for continuous measurement of the vertical distance from aircraft to land surface, so that the desired terrain profile can then be directly computed. The APT system, installed in a DeHavilland Twin Otter aircraft, is typically flown at a speed of 115 mph (105 knots) at an altitude of 2,000 ft (610 m) above the terrain. Performance-evaluation flights have shown that the vertical and horizontal accuracy specifications are met. (USGS)

We developed the 16-item Patient-Reported Arthralgia Inventory (PRAI to measure arthralgia severity in 16 joints, in the context of a longitudinal cohort study to assess aromatase inhibitor-associated arthralgia in breast cancer survivors and arthralgia in postmenopausal women without breast cancer. We sought to evaluate the reliability and validity of the PRAI instrument in these populations, as well as to examine the relationship of patient-reported morning stiffness and arthralgia. Methods: We administered the PRAI on paper in 294 women (94 initiating aromatase inhibitor therapy and 200 postmenopausal women without breast cancer at weeks 0, 2, 4, 6, 8, 12, 16, and 52, as well as once in 36 women who had taken but were no longer taking aromatase inhibitor therapy. Results: Cronbach's alpha was 0.9 for internal consistency of the PRAI. Intraclass correlation coefficients of test-retest reliability were in the range of 0.87–0.96 over repeated PRAI administrations; arthralgia severity was higher in the non-cancer group at baseline than at subsequent assessments. Women with joint comorbidities tended to have higher PRAI scores than those without (estimated difference in mean scores: -0.3, 95% confidence interval [CI] -0.5, -0.2; P<0.001. The PRAI was

    The objective of this study was to develop a valid and reliable instrument to measure the job satisfaction of physicians practicing emergency medicine. A prospective survey involving four separate stages (an item evaluation and reduction stage, a factor analysis stage, a construct validity stage, and a reliability stage) was distributed in Canada to full-time emergency physicians. Three separate survey instruments were administered (an initial draft instrument with 228 items, a pilot instrument with 142 items, and the final instrument with 79 items). Construct validity of the final instrument was tested by evaluating the correlation between physician scores on the instrument, and scores on two instruments measuring the same construct, and three measuring different but related constructs. A draft instrument with 228 items and six hypothetical domains was tested on 61 physicians. Evaluation for frequency endorsement, redundancy, and homogeneity reduced the item pool to 157. The remaining 157 items were used as a pilot instrument and tested on 223 physicians. Factor analysis eliminated 66 items from the pilot instrument, creating a final instrument with 79 items, 11 factors, and six domains. Cronbach's coefficient alpha for the final instrument domains is 0.81, and all domain-total correlations are greater than 0.4. All correlations between the final instrument and the construct validity instruments were statistically significant (P job satisfaction, which is both internally consistent and stable.

    The Student Human Papillomavirus Survey (SHPVS) was developed to examine students' perceived benefits or barriers to human papillomavirus (HPV) vaccination. Survey development included (a) 2-phase integrative literature reviews; (b) draft of survey items based on the literature; (c) critique of survey items by young adults, nursing and psychology faculty, and health care providers; and (d) pilot testing. The psychometric properties of the SHPVS were evaluated using classical item analysis and exploratory factor analysis (EFA) among a sample of 527 university students' ages 18-24 years. The estimated Cronbach's alpha for the SHPVS is .74. The SHPVS is a measure of young adults HPV perceived vulnerability, perceived severity, perceived barriers, and perceived benefits of HPV vaccination.

    Triggering instrumentation for autonomous monitoring of load-induced strain is described for economical, fast bridge inspection. The development addresses one aspect for the management of transportation infrastructure - bridge monitoring and inspection. The objectives are to provide quantitative performance information from a load test, to minimize the setup time at the bridge, and to minimize the closure time to traffic. Multiple or networked measurements can be made for a prescribed loading sequence. The proposed smart system consists of in-situ strain sensors, an embedded data acquisition module, and a measurement triggering system. A companion control unit is mounted on the truck serving as the load. As the truck moves to the proper position, the desired measurement is automatically relayed back to the control unit. In this work, the testing protocol is developed and the performance parameters for the triggering and data acquisition are measured. The test system uses a dedicated wireless sensor mote and an infrared positioning system. The electronic procedure offers improvements in available information and economics.

    Through the use of multi-modal methods, the purpose of this study was to develop and assess measurement properties of an instrument evaluating specific sexual behaviors of college students and the role alcohol intoxication plays in one's intention to participate in these behaviors. A modified version of N. Krause's instrument development process was applied to create a behavior-specific instrument assessing oral, vaginal, and anal sex behaviors. The process included a review by expert scholars in relevant fields, cognitive interviews with the target population using screen-capture program Camtasia, piloting to assess measurement scales, and a formal investigation. The applied instrument development process employed screen capture software and web-based surveying in a cost-effective format suitable for mixed-method measurement development. The development and application of the instrument provides a clearer understanding of the relationship between alcohol use and sexual activity and aids in the development of effective public health interventions and policies.

    Institutions of higher education are now using Internet-based technology tools to conduct surveys for data collection. Research shows that the type and quality of responses one receives with online surveys are comparable with what one receives in paper-based surveys. Data collection can take place on Web-based surveys, e-mail-based surveys, and personal digital assistants/Smartphone devices. Web surveys can be subscription templates, software packages installed on one's own server, or created from scratch using Web programming development tools. All of these approaches have their advantages and disadvantages. The survey owner must make informed decisions as to the right technology to implement. The correct choice can save hours of work in sorting, organizing, and analyzing data.

    Human papillomavirus (HPV) vaccine was approved for girls aged 9-24 years in 2006 to prevent HPV infection and cervical cancer. The Parental Human Papillomavirus Survey (PHPVS) was framed on theoretical constructs of the health belief model (HBM) and developed to survey parents regarding their HPV knowledge, attitudes, and intent to vaccinate. We evaluated the psychometric properties of the PHPVS using classical item analysis and exploratory factor analysis (EFA) among a sample of 200 parents/caregivers. The EFA yielded a 4-factor unidimensional model that explained between 62% and 68% of the total variance depending on the extraction method used. The estimated Cronbach's alpha for the PHPVS was .96. The PHPVS is a reliable measure of HPV knowledge, attitudes, and intent to vaccinate.

    Full Text Available Abstract Background The primary objective was to systematically review the medical literature for instruments validated for use in epidemiological and clinical research on waterpipe smoking. Methods We searched the following databases: MEDLINE, EMBASE, and ISI the Web of Science. We selected studies using a two-stage duplicate and independent screening process. We included papers reporting on the development and/or validation of survey instruments to measure waterpipe tobacco consumption or related concepts. Two reviewers used a standardized and pilot tested data abstraction form to collect data from each eligible study using a duplicate and independent screening process. We also determined the percentage of observational studies assessing the health effects of waterpipe tobacco smoking and the percentage of studies of prevalence of waterpipe tobacco smoking that have used validated survey instruments. Results We identified a total of five survey instruments. One instrument was designed to measure knowledge, attitudes, and waterpipe use among pregnant women and was shown to have internal consistency and content validity. Three instruments were designed to measure waterpipe tobacco consumption, two of which were reported to have face validity. The fifth instrument was designed to measure waterpipe dependence and was rigorously developed and validated. One of the studies of prevalence and none of the studies of health effects of waterpipe smoking used validated instruments. Conclusions A number of instruments for measuring the use of and dependence on waterpipe smoking exist. Future research should study content validity and cross cultural adaptation of these instruments.

    To evaluate French residents in Obstetrics and Gynaecology's training in instrumental deliveries in 2015. We conducted a national descriptive survey among 758 residents between December 2014 and January 2015. Respondents were invited by email to specify their University Hospital, their current university term, the number of instrumental deliveries performed by vacuum extractor, forceps or spatulas, and whether they made systematic ultrasound exams before performing the extraction. Response rate was 34.7 % (n=263). There were important differences between regions in terms of type of instruments used. Vacuum extractor was the most commonly used instrument for instrumental deliveries by French residents (56.9 %), more than forceps (25.2 %) and spatulas (17.9 %). At the end of the residency, all the residents had been trained in instrumental deliveries with at least two instruments. The training of difficult techniques as well as their perfect control is required for instrumental deliveries. Yet, we are forced to note that there are substantial differences in the French residents' training in instrumental deliveries depending on their region. So, teaching at least two techniques seems essential as well as improving the training capacities and standardizing practices. A greater systematization of the teaching of the mechanics and obstetric techniques might be a solution to be considered too. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

    Argonne National Laboratory (ANL) is reviewing the survey research studies completed by Mountain West Research (1987-1989) for the state of Nevada`s Nuclear Waste Project Office. In this research, 14 survey instruments were used to seek data on whether perceptions of risk could be associated with the possible siting of a high-level radioactive waste repository in Nevada and could be a dominant source of potential, significant, adverse economic impacts. This report presents results from phase 1 of the review, in which ANL contracted with the National Opinion Research Center (NORC) at the University of Chicago to evaluate the technical merits of the nine survey instruments that ANL had been able to acquire. The scope of NORC`s work was limited to rating the questions and stating their strengths and weaknesses. NORC concluded that the surveys could provide valuable data about risk perceptions and potential behavioral responses. NORC identified a few minor problems with a number of questions and the calculated response rates but claimed these problems would probably not have any major biasing effect. The NORC evaluation would have been more complete if the terms used in the questionnaires had been defined, all survey instruments had been acquired, and all data had been made available to the public.

    New safeguards requirements, such as those resulting from industrial reprocessing activities, makes the faster and more accurate determination of the uranium enrichment and/or the isotopic composition of plutonium essential in measuring the fissile mass. In response to these needs, Canberra has developed several improved safeguards systems in the last few years. In this paper, we will present an overview of our newest safeguards systems and the improvements they contain. The portable systems include the U-Pu InSpector, the IMCA and the JSR-14 systems. All combine automatic control of acquisition electronics and rapid analysis with an integrated software package for ease of use. The U-Pu InSpector incorporates the MGA code used by the IAEA and Euratom for plutonium analysis. The IMCA complies with IAEA PMCN and PMCG procedures for uranium analysis. With the JSR-14, we are currently developing the procedures to provide compliance with the IAEA neutron counting procedures. In addition to portable safeguards systems, Canberra has designed and installed many installed systems such as the WDAS and PSMC systems at PNC Tokai in Japan, and the large unattended neutron/gamma systems at Cogema La Hague and the Melox reprocessing facility in France.

    This white paper offers cautionary observations about the planning and development of new, large radio astronomy instruments. Complexity is a strong cost driver so every effort should be made to assign differing science requirements to different instruments and probably different sites. The appeal of shared resources is generally not realized in practice and can often be counterproductive. Instrument optimization is much more difficult with longer lists of requirements, and the development process is longer and less efficient. More complex instruments are necessarily further behind the technology state of the art because of longer development times. Including technology R&D in the construction phase of projects is a growing trend that leads to higher risks, cost overruns, schedule delays, and project de-scoping. There are no technology breakthroughs just over the horizon that will suddenly bring down the cost of collecting area. Advances come largely through careful attention to detail in the adoption of ...

    Rapid recognition and treatment of myocardial infarction (MI) reduces morbidity and mortality. Although emergency department (ED) nurses are often the first provider to evaluate individuals and are in a prime position to initiate MI guideline recommendations, no valid and reliable instrument was found to quantify their decision-making processes. The purpose of this study was to develop and test the psychometric properties of a new theoretically driven, empirically based instrument for measuring nurses' cardiac triage decisions. Using a descriptive research design, data were collected using a mailed survey. There were 158 ED nurses who completed a mailed questionnaire. Factor analysis revealed three factors (patient presentation, unbiased nurse reasoning process, and nurse action) with good internal consistency (Cronbach's alpha = .903, .809, .718) and sample adequacy (KMO = .758) of the 30-item instrument. The newly developed instrument has the potential to improve patient outcomes surrounding early MI identification and treatment.

    A survey oriented towards identifying the human factors issues in regard to the use of advanced instrumentation and controls (I C) in the nuclear industry was conducted. A number of United States (US) and Canadian nuclear vendors and utilities were participants in the survey. Human factors items, subsumed under the categories of computer-generated displays (CGD), controls, organizational support, training, and related topics, were discussed. The survey found the industry to be concerned about the human factors issues related to the implementation of advanced I C. Fifteen potential human factors problems were identified. They include: the need for an advanced I C guideline equivalent to NUREG-0700; a role change in the control room from operator to supervisor; information overload; adequacy of existing training technology for advanced I C; and operator acceptance and trust. 11 refs., 1 tab.

    This article introduces a development of pulsed neutron uranium logging instrument. By analyzing the temporal distribution of epithermal neutrons generated from the thermal fission of {sup 235}U, we propose a new method with a uranium-bearing index to calculate the uranium content in the formation. An instrument employing a D-T neutron generator and two epithermal neutron detectors has been developed. The logging response is studied using Monte Carlo simulation and experiments in calibration wells. The simulation and experimental results show that the uranium-bearing index is linearly correlated with the uranium content, and the porosity and thermal neutron lifetime of the formation can be acquired simultaneously.

    Advances in instrumentation have proceeded at an impressive rate since the invention of the electron microscope. These advances have produced a continuous expansion of the capabilities and range of application of electron microscopy. In order to provide some insights on how continuing advances may enhance cryo-electron microscopy and electron crystallography, we review some of the active areas of instrumentation development. There is strong momentum in areas including detectors, phase contrast devices, and aberration correctors that may have substantial impact on the productivity and expectations of electron crystallographers.

    A wide field space-based imaging telescope is necessary to fully exploit the technique of observing dark matter via weak gravitational lensing. This first paper in a three part series outlines the survey strategies and relevant instrumental parameters for such a mission. As a concrete example of hardware design, we consider the proposed Supernova/Acceleration Probe (SNAP). Using SNAP engineering models, we quantify the major contributions to this telescope's Point Spread Function (PSF). These PSF contributions are relevant to any similar wide field space telescope. We further show that the PSF of SNAP or a similar telescope will be smaller than current ground-based PSFs, and more isotropic and stable over time than the PSF of the Hubble Space Telescope. We outline survey strategies for two different regimes - a ''wide'' 300 square degree survey and a ''deep'' 15 square degree survey that will accomplish various weak lensing goals including statistical studies and dark matter mapping.

    SCK-CEN's research and development programme on instrumentation involves the assessment and the development of sensitive measurement systems used within a radiation environment. Particular emphasis is on the assessment of optical fibre components and their adaptability to radiation environments. The evaluation of ageing processes of instrumentation in fission plants, the development of specific data evaluation strategies to compensate for ageing induced degradation of sensors and cable performance form part of these activities. In 2000, particular emphasis was on in-core reactor instrumentation applied to fusion, accelerator driven and water-cooled fission reactors. This involved the development of high performance instrumentation for irradiation experiments in the BR2 reactor in support of new instrumentation needs for MYRRHA, and for diagnostic systems for the ITER reactor.

    CHEOPS (CHaracterizing ExOPlanets Satellite) is the first ESA Small Mission as part of the ESA Cosmic Vision program 2015-2025. The mission was formally adopted in early February 2014 with a planned launch readiness end of 2017. The mission lead is performed in a partnership between Switzerland, led by the University of Bern, and the European Space Agency with important contributions from Austria, Belgium, France, Germany, Hungary, Italy, Portugal, Spain, Sweden, and the United Kingdom. The mission is dedicated to searching for exoplanetary transits by performing ultrahigh precision photometry on bright starts already known to host planets whose mass has been already estimated through ground based observations. The instrument is an optical Ritchey-Chretien telescope of 30 cm clear aperture using a single CCD detector. The optical system is designed to image a de-focused PSF onto the focal plane with very stringent stability and straylight rejection requirements providing a FoV of 0.32 degrees full cone. The system design is adapted to meet the top-level science requirements, which ask for a photometric precision of 20ppm, in 6 hours integration time, on transit measurements of G5 dwarf stars with V-band magnitudes in the range 6≤V≤9 mag. Additionally they ask for a photometric precision of 85 ppm in 3 hours integration time of Neptune-size planets transiting K-type dwarf stars with V-band magnitudes as faint as V=12 mag. Given the demanding schedule and cost constrains, the mission relies mostly on components with flight heritage for the platform as well as for the payload components. Nevertheless, several new developments are integrated into the design as for example the telescope structure and the very low noise, high stability CCD front end electronics. The instrument and mission have gone through critical design review in fall 2015 / spring 2016. This paper describes the current instrument and mission design with a focus on the instrument. It outlines the

    The characterization of atmospheric turbulence at and above the two candidate sites for the 15 m National New Technology Telescope (NNTT) has required the development of specialized measurement techniques. The equipment used to measure astronomical seeing, microthermals, water vapor, and temperature is discussed, along with sample data and calibration results. By use of instruments with overlapping altitude coverage, it has been possible to 'bookkeep' qualitatively all of the sources of innate degradation, especially near the ground.

    The next generation of multi-object spectrographs (MOS) will deliver comprehensive surveys of the Galaxy, Magellanic Clouds and nearby dwarfs. These will provide us with the vast samples, spanning the full extent of the Hertzsprung-Russell diagram, that are needed to explore the chemistry, history and dynamics of their host systems. Further ahead, the Extremely Large Telescopes (ELTs) will have sufficient sensitivity and angular resolution to extend stellar spectroscopy well beyond the Local Group, opening-up studies of the chemical evolution of galaxies across a broad range of galaxy types and environments. In this contribution I briefly reflect on current and future studies of stellar populations, and introduce plans for the MOSAIC instrument for the European ELT.

    New water-level sensing and recording instrumentation is being used by the U.S. Geological Survey for monitoring water levels, stream velocities, and water-quality characteristics. Several of these instruments are briefly described. The Basic Data Recorder (BDR) is an electronic data logger, that interfaces to sensor systems through a serial-digital interface standard (SDI-12), which was proposed by the data-logger industry; the Incremental Shaft Encoder is an intelligent water-level sensor, which interfaces to the BDR through the SDI-12; the Pressure Sensor is an intelligent, nonsubmersible pressure sensor, which interfaces to the BDR through the SDI-12 and monitors water levels from 0 to 50 feet; the Ultrasonic Velocity Meter is an intelligent, water-velocity sensor, which interfaces to the BDR through the SDI-12 and measures the velocity across a stream up to 500 feet in width; the Collapsible Hand Sampler can be collapsed for insertion through holes in the ice and opened under the ice to collect a water sample; the Lighweight Ice Auger, weighing only 32 pounds, can auger 6- and 8-inch holes through approximately 3.5 feet of ice; and the Ice Chisel has a specially hardened steel blade and 6-foot long, hickory D-handle.

    2008-08-01

    A survey instrument using everyday teaching scenarios was developed to measure teacher conceptions of inquiry. Validity of the instrument was established by comparing responses for a group of secondary teachers to narrative writing and group discussion. Participating teachers used only three of the five essential features of inquiry detailed in the standards documents (NRC 2000) when expressing their ideas of classroom inquiry. The features of ‘evaluating explanations in connection with scientific knowledge’ and ‘communicating explanations’ were rarely mentioned. These missing components indicate a gap between the teachers’ conceptions of inquiry and the ideals of the reform movement.

    2013-04-01

    Advances in medical imaging, in particular positron emission tomography (PET), have been based on technical developments in physics and instrumentation that have common foundations with detection systems used in other fields of physics. New detector materials are used in PET systems that maximize efficiency, timing characteristics and robustness, and which lead to improved image quality and quantitative accuracy for clinical imaging. Time of flight (TOF) techniques are now routinely used in commercial PET scanners that combine physiological imaging with anatomical imaging provided by x-ray computed tomography. Using new solid-state photo-sensors instead of traditional photo-multiplier tubes makes it possible to combine PET with magnetic resonance imaging which is a significant technical challenge, but one that is creating new opportunities for both research and clinical applications. An overview of recent advances in instrumentation, such as TOF and PET/MR will be presented, along with examples of imaging studies to demonstrate the impact on patient care and basic research of diseases.

    Most measures of cognitive function used in large-scale surveys of older adults have limited ability to detect subtle differences across cognitive domains, and standard clinical instruments are impractical to administer in general surveys. The Montreal Cognitive Assessment (MoCA) can address this need, but has limitations in a survey context. Therefore, we developed a survey adaptation of the MoCA, called the MoCA-SA, and describe its psychometric properties in a large national survey. Using a pretest sample of older adults (n=120), we reduced MoCA administration time by 26%, developed a model to accurately estimate full MoCA scores from the MoCA-SA, and tested the model in an independent clinical sample (n=93). The validated 18-item MoCA-SA was then administered to community-dwelling adults aged 62 to 91 as part of the National Social life Health and Aging Project Wave 2 sample (n=3196). In National Social life Health and Aging Project Wave 2, the MoCA-SA had good internal reliability (Cronbach α=0.76). Using item-response models, survey-adapted items captured a broad range of cognitive abilities and functioned similarly across sex, education, and ethnic groups. Results demonstrate that the MoCA-SA can be administered reliably in a survey setting while preserving sensitivity to a broad range of cognitive abilities and similar performance across demographic subgroups.

    2013-03-01

    Full Text Available Orientation: An instrument based on a theoretical model is necessary to measure the positive side of the work-family interface.Research purpose: To develop items for measurement of work-family enrichment based on the elements contained within a theoretical model and to evaluate the latent trait functioning of these items.Motivation for the study: Major limitations exist regarding the conceptualisation and scale development of the positive side of the work-family interface.Research design, approach, and method: A quantitative research approach using scale development procedures was employed to develop the 95-item instrument. A cross-sectional survey design was used to collect data randomly from selected employees; data were processed using Rasch analysis.Main findings: The five-category scale works well for the most part, although a four-category scale could be considered. Thirty-five items either over-fitted or under-fitted the work-family enrichment model. Person ability was measured in the low to middle ranges of work-family enrichment. Participants’ experience of work-family enrichment could be represented accurately. Sub-scale items displayed misfit, bias or both.Practical/managerial implications: The developed instrument can be investigated further to identify work-family enrichment factors that can measure workers’ experience of enrichment in their work and family domains.Contribution/value-add: This study furthers theory building and empirical research in industrial psychology, by developing a new theory-based measuring instrument for the positive side of the work-family interface in the South African context. This study expanded on the model proposed by Greenhaus and Powell, by including all five categories of resources gains. Furthermore, the total of the resources was diversified, since some of the content of these resources encompasses multiple meanings.

    The Multi-sensor Airborne Radiation Survey (MARS) project has developed a new single cryostat detector array design for high purity germanium (HPGe) gama ray spectrometers that achieves the high detection efficiency required for stand-off detection and actionable characterization of radiological threats. This approach, we found, is necessary since a high efficiency HPGe detector can only be built as an array due to limitations in growing large germanium crystals. Moreover, the system is ruggedized and shock mounted for use in a variety of field applications, including airborne and maritime operations.

    1990-01-01

    A new velocimetry system is currently being developed at NASA LaRC. The device, known as a Doppler global velocimeter (DGV), can record three velocity components within a plane simultaneously and in near real time. To make measurements the DGV, like many other velocimetry systems, relies on the scattering of light from numerous small particles in a flow field. The particles or seeds are illuminated by a sheet of laser light and viewed by two CCD cameras. The scattered light from the particles will have a frequency which is a function of the source laser light frequency, the viewing angle, and most importantly the seed velocities. By determining the scattered light intensity the velocity can be measured at all points within the light sheet simultaneously. Upon completion of DGV component construction and initial check out a series of tests in the Basic Aerodynamic Research (wind) Tunnel (BART) are scheduled to verify instrument operation and accuracy. If the results are satisfactory, application of the DGV to flight measurements on the F-18 High Alpha Research Vehicle (HARV) are planned. The DGV verification test in the BART facility will utilize a 75 degree swept delta wing model. A major task undertaken this summer included evaluation of previous results for this model. A specific series of tests matching exactly the previous tests and exploring new DGV capabilities were developed and suggested. Another task undertaken was to study DGV system installation possibilities in the F-18 HARV aircraft. In addition, a simple seeding system modification was developed and utilized to make Particle Imaging Velocimetry (PIV) measurements in the BART facility.

    Based on the law of physics, known as "Seebeck effect," a thermoelectric generator (TEG) produces electricity when the temperature differential is applied across the TEG. This article reports a precision method in characterizing TEG modules. A precision instrument is constructed to study thermoelectric conversion in terms of output power and efficiency of TEG modules. The maximum allowable TEG module size is 150 mm, and the preferred size is from 30 mm to 60 mm. During measurements, the highest hot side temperature is 500 °C and the cold side temperature can be adjusted from room temperature to 100 °C. A mechanical structure is developed to control the pressure and parallelism of the clamping force of the TEG on both its hot and cold sides. A heat flux measurement module is installed at its cold side, and the heat flux through TEGs can be measured in position. Finally, the energy conversion efficiency of TEGs is calculated from experimental data of both an output power and a heat flux.

    The human brain functions through a chemically-induced biological process which operates in a manner similar to electrical systems. The signal resulting from this biochemical process can actually be monitored and read using tools and having patterns similar to those found in electrical and electronics engineering. The primary signature of this electrical activity is the ''brain wave'', which looks remarkably similar to the output of many electrical systems. Likewise, the device currently used in medical arenas to read brain electrical activity is the electroencephalogram (EEG) which is synonymous with a multi-channel oscilloscope reading. Brain wave readings and recordings for medical purposes are traditionally taken in clinical settings such as hospitals, laboratories or diagnostic clinics. The signal is captured via externally applied scalp electrodes using semi-viscous gel to reduce impedance. The signal will be in the 10 to 100 microvolt range. In other instances, where surgeons are attempting to isolate particular types of minute brain signals, the electrodes may actually be temporarily implanted in the brain during a preliminary procedure. The current configurations of equipment required for EEGs involve large recording instruments, many electrodes, wires, and large amounts of hard disk space devoted to storing large files of brain wave data which are then eventually analyzed for patterns of concern. Advances in sensors, signal processing, data storage and microelectronics over the last decade would seem to have paved the way for the realization of devices capable of ''real time'' external monitoring, and possible assessment, of brain activity. A myriad of applications for such a capability are likewise presenting themselves, including the ability to assess brain functioning, level of functioning and malfunctioning. Our plan is to develop the sensors, signal processing, and portable instrumentation package which could

    The purpose of this study was to evaluate, through a systematic review, assessment instruments for evidence-based practice (EBP). The specific objectives were to (1) identify survey instruments testing EBP knowledge, skills, attitudes and behaviour; (2) determine the attributes measured by each instrument; (3) evaluate the psychometric properties of the instruments; and (4) evaluate the methodological quality of the instruments. Using the Cochrane approach, searches were conducted in Pubmed, EBSCOHost and Scopus from inception to February 2014. Papers were screened by two independent assessors, and data were extracted by one researcher. Forty papers reporting 34 instruments met the inclusion criteria and were included in the qualitative synthesis. Most instruments measured EBP behaviour (n = 33) and attitudes (n = 21). This review provides a single source of information to enable researchers to select the most robust descriptive instruments to measure EBP learner attributes. Instruments used only with occupational therapists may have resulted in some instruments being missed. For further research, it is recommended that attention is given to developing objective instruments with a focus on knowledge and skills. Copyright © 2015 John Wiley & Sons, Ltd.

    Teamwork in health care settings is widely recognized as an important factor in providing high-quality patient care. However, the behaviors that comprise effective teamwork, the organizational factors that support teamwork, and the relationship between teamwork and patient outcomes remain empirical questions in need of rigorous study. To identify and review survey instruments used to assess dimensions of teamwork so as to facilitate high-quality research on this topic. We conducted a systematic review of articles published before September 2012 to identify survey instruments used to measure teamwork and to assess their conceptual content, psychometric validity, and relationships to outcomes of interest. We searched the ISI Web of Knowledge database, and identified relevant articles using the search terms team, teamwork, or collaboration in combination with survey, scale, measure, or questionnaire. We found 39 surveys that measured teamwork. Surveys assessed different dimensions of teamwork. The most commonly assessed dimensions were communication, coordination, and respect. Of the 39 surveys, 10 met all of the criteria for psychometric validity, and 14 showed significant relationships to nonself-report outcomes. Evidence of psychometric validity is lacking for many teamwork survey instruments. However, several psychometrically valid instruments are available. Researchers aiming to advance research on teamwork in health care should consider using or adapting one of these instruments before creating a new one. Because instruments vary considerably in the behavioral processes and emergent states of teamwork that they capture, researchers must carefully evaluate the conceptual consistency between instrument, research question, and context.

    Both personal digital assistants (PDAs) and tablet computers have emerged to facilitate data collection at the point of care. However, little research has been reported comparing these mobile computing devices in specific care settings. In this study we present an approach for comparing functionally identical applications on a Palm operating system-based PDA and a Windows-based tablet computer for point-of-care documentation of clinical observations by eye care professionals when caring for patients with diabetes. Eye-care professionals compared the devices through focus group sessions and through validated usability surveys. This poster describes the development and use of the survey instrument used for comparing mobile computing devices. PMID:16779327

  17. Developing an Instrument to Examine Preservice Teachers' Pedagogical Development

    Science.gov (United States)

    Hudson, Peter; Ginns, Ian

    2007-12-01

    National and international reform documents have forged blueprints for advancing science education. Coursework for preservice teachers needs to correspond to these documents by providing learning experiences that develop preservice teachers’ capabilities to plan and implement reform measures. Using a pretest-posttest design, responses from 59 2nd-year preservice teachers from the same university were compared after involvement in an elementary science pedagogy coursework. The survey, which was linked to the course outcomes (constructs) and multiple indicators, measured the preservice teachers’ perceptions of their development towards becoming elementary science teachers. A pretest-posttest survey linked to course outcomes can be employed to assess perceived pedagogical development of preservice teachers, which can inform further teaching practices for implementing science education reform agendas.

    2010-01-01

    We present the design and scientific objectives behind NESSI, a near-infrared spectroscopic purpose-built for studying exoplanet atmospheres. This instrument is being designed and assembled by a team of scientists and engineers at New Mexico Tech (NMT), the Magdalena Ridge Observatory (MRO) and NASA's Jet Propulsion Lab (JPL), and is scheduled for deployment in late 2010 at the MRO 2.4m telescope. NESSI's unique design is driven by recent space and ground-based NIR spectroscopy of exoplanet atmospheres by members of our team. Optimization of the instrument to achieve 0.01% relative accuracies in spectra of exoplanetary molecular constituents requires careful attention to certain design features and a new technical approach. We present an overview of NESSI's design, including the four major subassemblies: 1) a field derotator, 2) a reimaging module, 3) an optical guiding module, and 4) a multi-object spectrograph subassembly. We also present an overview of our science program specifically designed to build the community of exoplanet researchers and students in NM. The financial support of our team and NESSI itself have been made possible by a NM NASA EPSCoR grant, matching funds from the NMT administration, and internal support for the NESSI hardware from Dr. Van Romero, NMT's Research Vice-President.

    2010-12-01

    Full Text Available Abstract Background Clinical risk management (CRM plays a crucial role in enabling hospitals to identify, contain, and manage risks related to patient safety. So far, no instruments are available to measure and monitor the level of implementation of CRM. Therefore, our objective was to develop an instrument for assessing CRM in hospitals. Methods The instrument was developed based on a literature review, which identified key elements of CRM. These elements were then discussed with a panel of patient safety experts. A theoretical model was used to describe the level to which CRM elements have been implemented within the organization. Interviews with CRM practitioners and a pilot evaluation were conducted to revise the instrument. The first nationwide application of the instrument (138 participating Swiss hospitals was complemented by in-depth interviews with 25 CRM practitioners in selected hospitals, for validation purposes. Results The monitoring instrument consists of 28 main questions organized in three sections: 1 Implementation and organizational integration of CRM, 2 Strategic objectives and operational implementation of CRM at hospital level, and 3 Overview of CRM in different services. The instrument is available in four languages (English, German, French, and Italian. It allows hospitals to gather comprehensive and systematic data on their CRM practice and to identify areas for further improvement. Conclusions We have developed an instrument for assessing development stages of CRM in hospitals that should be feasible for a continuous monitoring of developments in this important area of patient safety.

  9. Z-Spec: A broadband spectrometer for millimeter-wave astrophysics---Instrument development and results of a molecular line survey of nearby star-forming galaxy NGC 253

    Science.gov (United States)

    Earle, Lieko

    We have built Z-Spec, a broadband spectrometer for millimeter-wave astrophysics. The instrument's instantaneous bandwidth of 185-305 GHz covers the entire 1 millimeter atmospheric transmission window with a moderate resolving power ( R = n/Dn) of 250-350. The spectrometer employs a novel architecture called WaFIRS (Waveguide Far-Infrared Spectrometer) which confines the light propagation for a curved diffraction grating within a parallel-plate waveguide, resulting in a minimum mechanical envelope. An array of 160 silicon- nitride micromesh bolometers is cooled to 60 mK via an adiabatic demagnetization refrigerator (ADR) backed by a closed-cycle 3 He- 4 He sorption pump refrigerator. Z-Spec's compact design serves as a concept demonstration for a future far-infrared spectrometer aboard a cold telescope in space. Routine observations with Z-Spec from the Caltech Submillimeter Observatory on Mauna Kea have been conducted since April 2006, and the instrument currently achieves good sensitivities that are within a factor of two of the photon background limit set by the atmosphere and telescope. Z-Spec's primary science objectives are to determine the redshifts of faint submillimeter galaxies using the 12 CO rotational ladder, and to conduct systematic line surveys of local galaxies. The millimeter waveband hosts low- to mid- J rotational transitions for several molecular species which trace the dense interstellar gas associated with active star formation. Z-Spec's bandwidth offers a unique advantage over the traditional single-dish heterodyne approach: the spectral lines and the corresponding continua are all observed simultaneously, greatly reducing relative uncertainties in flux calibration and line-to-continuum ratios. The starburst galaxy NGC 253 was observed with Z-Spec in November 2006, for a total integration of 3.49 hours over two nights. NGC 253 is one of the brightest neighbors outside the Local Group of galaxies and its compact nuclear region is a site of

    At the Pisgah Astronomical Research Institute (PARI) in Rosman, NC I spent 8 weeks as the NC Space Grant/J. Donald Cline Astronomy Scholar. I developed multiple projects and assisted as a mentor to PARI Space Science Lab and Duke TIP high school gifted student program which both took place during my stay. My main focus was the development of the Polaris imaging telescope. This telescope is used to take images of the pulsating variable star Polaris. These readings are used to make seeing estimates for the air column above PARI. The system stores and archives images and analyzes them for magnitude change and movement of the stellar image. In addition to the Polaris project I developed a solar panel voltage and charge monitoring system which involved me working with charge controllers and photovoltaic technology. I developed a charging scheme using Flexmax 60 charge controller. Data is recorded and transmitted via optical fiber for analysis and correlation with solar zenith angle.

    2006-10-01

    With the aim of developing a new dietary instrument for assessing an individual's usual intakes, we evaluated a hand-held personal digital assistant with camera and mobile telephone card, called Wellnavi (Matsushita Electric Works, Ltd, Osaka, Japan). Twenty-eight college students majoring in food and nutrition in Okayama University of Japan voluntarily participated in this study. Applying a cross-sectional study design, participants were asked to keep 1-day weighed food records. Digital images of all recorded foods were obtained simultaneously and sent to registered dietitians by a mobile telephone card. The following day, a 24-hour recall was obtained. These procedures were repeated after 6 months. Participants' opinions about the three methods were determined using a questionnaire. Differences in estimated median nutrient intake among the three methods were compared by Wilcoxon matched-pairs signed rank test. Relationships among the nutrient estimates by each method were evaluated using Spearman rank correlation coefficients. We found no significant differences between the Wellnavi method when compared with food records for most nutrients, except zinc, manganese, vitamin E, saturated fatty acid, polyunsaturated fatty acid, and dietary fiber. The median correlation coefficients for the nutrient estimates were 0.66 between the Wellnavi method and the food records. The survey showed that 57.1% of subjects considered the Wellnavi method the least burdensome of the three methods and the least time consuming (16 minutes) to record daily diet. About half of participants indicated that they would be willing to use the Wellnavi for 1 month to record their diet. This study suggests that a hand-held digital assistant may be a valid and convenient instrument for evaluating dietary intake.

    Food choices are influenced by an individual's attitude towards foods. Food neophobia may be associated with less variety of diets, inadequate nutrient intake and high product failure rate for new food products entering the market. To quantify the extent of these challenges, instruments to measure the food neophobia in different target groups are needed. Several such instruments with significantly different measurement outcomes and procedures have been developed. This review provides an overview and discusses strengths and weaknesses of these instruments. We evaluate strengths and weaknesses of previously developed instruments to measure neophobia and willingness to try unfamiliar foods. Literature was searched through the databases Web of Science and Google Scholar. We identified 255 studies concerning neophobia and willingness to try unfamiliar foods. Of these, 13 studies encompassing 13 instruments to measure neophobia and willingness to try unfamiliar foods were included in the review. Results are summarized and evaluated with a narrative approach. In the 13 instruments to assess neophobia and willingness to try unfamiliar foods, 113 to 16.644 subjects aged 2-65 years were involved, scales with 3-7 response categories were used and behavioral validation tests were included in 6 studies. Several instruments to measure neophobia and willingness to try unfamiliar foods exist. We recommend selecting one or more among the 13 instruments reviewed in this paper to assess relevant aspects of neophobia. Copyright © 2017 The Authors. Published by Elsevier Ltd..

    1999-01-01

    Economic theory suggests that willingness to pay for two goods independently offered should remain unchanged when the survey instrument changes slightly. Four survey treatments consisting of comprehensive good and a subset of that good were used. The surveys alternated in the question ordering and in the embedded good which accompanied the comprehensive good. We tested for sequencing and instrument context effects using both a combined and split sample designs. In the combined sample case we found some evidence to sequencing effects in the data containing the first subset good. Likelihood ratio tests indicated that sequencing did not effect scale or location of parameters. In the test for instrument context effects, evidence was found indicating context does effect willingness to pay estimates.

. A more comprehensive understanding of attitudes and barriers related to FP will guide the building of optimal systems that support effective FP options, resources, and programs for individuals with cancer.

  4. The development of an instrument to assess chemistry perceptions

    Science.gov (United States)

    Wells, Raymond R.

    The instrument, developed in this study, attempted to correct the deficiencies of previous instruments. Statements of belief and opinion can be validly included under the construct of chemistry perceptions. Further, statements that might be better characterized as science attitudes, math attitudes, or attitudes toward a specific course or program were not included. Eliminating statements of math anxiety and test anxiety insured that responses to statements of anxiety were perceptions of anxiety solely related to chemistry. The results of the expert judges' responses to the Validation of Proposed Perception Statements forms were detailed to establish construct and content validity. The nature of Likert scale construction and calculation of internal consistency also supported the validity of the instrument. A pilot Chemistry Perception Questionnaire (CPQ) was then constructed based on agreement of the appropriate subscale and mean importance of the perception statements. The pilot CPQ results were subjected to an item analysis based on three sets of statistics: the frequency of each response and the percentage of respondents making each response for each perception statement, the mean and standard deviations for each item, and the item discrimination index which correlated the item scores with the subscale scores. With no zero or negative correlations to the subscale scores, it was not necessary to replace any of the perception statements contained in the pilot instrument. Therefore, the piloted Chemistry Perception Questionnaire became the final instrument. Factor analysis confirmed the multidimensionality of the instrument. The instrument was administered twice with a separation interval of approximately one month in order to perform a test-retest reliability analysis. One hundred and forty-one pairs were matched and results detailed. The correlation between forms, for the total instrument, was 0.9342. The mean coefficient alpha, for the total instrument, was 0

    Full Text Available Innovation is seen in numerous specialized studies as an efficient method for improving the performance of a company based on the sector in which that company operates. Based on this idea, the article aims to determine the nature of inter-correlation between the innovation activity of companies and the level of performance of these, which are the main types of innovation and how they can influence companies` position and how the sector of activity can influence the dimension of the impact of innovation. For achieve these objectives have been analysed empirical studies in various sectors, studies which have highlighted a positive inter-correlation between innovation activity and the performance of companies with significant differences depending on the type of innovation and industry use. The article is completed by an empirical analysis which aims to determine the extent to which performance of companies in the construction sector is sensitive to innovation activity. For the analysis were collected data from 14 companies which developed the specific activities in the construction sector of Europe, were achieve a total of 112 observations. The results obtained by applying a multiple regression model shows a positive correlation relationship between indicators of innovation (R&D expenditures and the value of patents/patents on the one side and performance indicators (equity, labour productivity and number of employees on the other side. Another direction of research analysed in this paper is to determine the impact of labour indicators on the level of innovation, in this situation was achieve a positive but insignificant inter-correlation between those indicators.

    This study developed and evaluated the Nurse Codependency Questionnaire (NCQ) and generated initial estimates of the stability and internal consistency of responses for the questionnaire. An initial pool of 95 items, reflective of four domains of codependency, was generated from the codependency literature using a domain-referenced approach. Seven expert judges from the nursing and codependency fields calculated the content validity index (CVI) as > .80. Items were critiqued for relevance, clarity, and predicted direction of each item's correlation with the total codependency score. A convenience sample of 547 male and female nurses from Texas was recruited from a variety of professional settings to test the NCQ. Evidence of reliability and validity was sought through the use of principal factor analysis (PFA) techniques and correlation analysis. The specific domains of "codependent caretaking" and "lack of voice" represented two of the four hypothesized domains that were supported by factor analysis. Data screening and item analysis resulted in a final sample of 24 items. Test-retest reliability was .90 and internal consistency reliability was .80 for the entire scale. Reliability estimates for the "codependent caretaking" and "lack of voice" scales were .65 and .59, respectively for test-retest; and .81 and .64, respectively for internal consistency. Known groups validity was supported by each of the factors' ability to discriminate between binge and nonbinge eaters. The NCQ may be useful for identifying codependency within the nursing profession. Research is needed to determine the external factors that influence the overt expression of nurse codependency. Screening for nurse codependency may contribute to the health of the profession by providing a means for anticipatory guidance and early intervention.

  8. Measuring social exclusion in routine public health surveys: construction of a multidimensional instrument.

    Addi P L van Bergen

    Full Text Available INTRODUCTION: Social exclusion is considered a major factor in the causation and maintenance of health inequalities, but its measurement in health research is still in its infancy. In the Netherlands the Institute for Social Research (SCP developed an instrument to measure the multidimensional concept of social exclusion in social and economic policy research. Here, we present a method to construct a similar measure of social exclusion using available data from public health surveys. METHODS: Analyses were performed on data from the health questionnaires that were completed by 20,877 adults in the four largest cities in the Netherlands. From each of the four questionnaires we selected the items that corresponded to those of the SCP-instrument. These were entered into a nonlinear canonical correlation analysis. The measurement properties of the resulting indices and dimension scales were assessed and compared to the SCP-instrument. RESULTS: The internal consistency of the indices and most of the dimension scales were adequate and the internal structure of the indices was as expected. Both generalisabiliy and construct validity were good: in all datasets strong associations were found between the index and a number of known risk factors of social exclusion. A limitation of content validity was that the dimension "lack of normative integration" could not be measured, because no relevant items were available. CONCLUSIONS: Our findings indicate that a measure for social exclusion can be constructed with available health questionnaires. This provides opportunities for application in public health surveillance systems in the Netherlands and elsewhere in the world.

    Full Text Available One of the principal issues in any university community is the lack of communication between community categories – leadership, administration, teaching staff and students. Sometimes is important to know in a short time the opinion of one particular group, without investing a lot of resources and without being extremely formal. The aim of this study was to test if an open-source platform – Moodle – can be used for quick surveys inside the Faculty of Medicine, UMF “Iuliu Hatieganu” Cluj-Napoca community. For this, on existing Moodle platform was installed one specific survey instrument – a questionnaire module and a survey containing a real life issue to the students of Faculty of Medicine was launched. The researchers have focused on how the specific problems of a survey - preparing of the survey, the survey process and the analysis of the results can be handle in Moodle. The pilot survey was a success; the conclusion of the study was that Moodle can be used as on-line survey instrument for that community.

    Full Text Available To contribute to understanding how teachers can develop geometrical understanding, we report on the discursive development of teachers’ geometrical reasoning through instrument appropriation while collaborating in an online dynamic geometry environment (DGE. Using the theory of instrument-mediated activity, we analysis the discourse and DGE actions of a group of middle and high school mathematics teachers who participated in a semester-long, professional development course. Working in small teams, they collaborated to solve geometric problems. Our results show that as teachers appropriate DGE artifacts and transform its components into instruments, they develop their geometrical knowledge and reasoning in dynamic geometry. Our study contributes to a broad understanding of how teachers develop mathematical knowledge for teaching.

    A growing body of qualitative and quantitative research suggests that individual patients and physicians often have differing perspectives, or 'explanatory models,' regarding the patient's health condition or illness. Discordance between explanatory models may lead to difficulties in communication and poor disease outcomes. However, due to a lack of tools to systematically measure concordance in patient and physician explanatory models, a large-scale study of explanatory models of illness has not been previously possible. The objective of this project was to develop and pilot-test a survey-based tool (the CONNECT Instrument) that measures salient aspects of explanatory models of illness. We conducted a multi-method survey development project that included qualitative and quantitative item development, refinement, pilot testing, and psychometric evaluation. We evaluated the instrument in two unique, consecutive cohorts of primary care patients in a variety of private and public settings in Houston, TX. We also used the instrument to examine concordance between patient and physician explanatory models in the second cohort. The final version of the CONNECT Instrument contains nineteen items that focus on six dimensions of explanatory models. Cronbach alphas ranged from 0.65 to 0.89 for the six CONNECT dimensions. The instrument demonstrated evidence of criterion-related validity when individual CONNECT dimension scores were compared with scores from previously published instruments, and demonstrated expected differences between patients 'and physicians' explanatory models of illness. The CONNECT instrument is a tool with good psychometric properties that enables researchers to measure important aspects of patients 'and physicians' explanatory models of illness. Our continuing work will focus on gathering additional validity evidence and evaluating associations between explanatory model concordance and health outcomes. The CONNECT instrument can be used to improve

    The Actual Curriculum Development Practices Instrument (ACDP-I) was developed and the factorial validity of the ACDP-I was tested (n = 107) using exploratory factor analysis procedures in the earlier work of [1]. Despite the ACDP-I appears to be content and construct valid instrument with very high internal reliability qualities for using in Malaysia, the accumulated evidences are still needed to provide a sound scientific basis for the proposed score interpretations. Therefore, the present study addresses this concern by utilising the confirmatory factor analysis to further confirm the theoretical structure of the variable Actual Curriculum Development Practices (ACDP) and enrich the psychometrical properties of ACDP-I. Results of this study have practical implication to both researchers and educators whose concerns focus on teachers' classroom practices and the instrument development and validation process.

    Measurement and our understanding of safety culture are still evolving. The objectives of this study were to assess variation in safety and teamwork climate and in the neonatal intensive care unit (NICU) setting, and compare measurement of safety culture scales using two different instruments (Safety Attitudes Questionnaire (SAQ) and Hospital Survey on Patient Safety Culture (HSOPSC)). Cross-sectional survey study of a voluntary sample of 2073 (response rate 62.9%) health professionals in 44 NICUs. To compare survey instruments, we used Spearman's rank correlation coefficients. We also compared similar scales and items across the instruments using t tests and changes in quartile-level performance. We found significant variation across NICUs in safety and teamwork climate scales of SAQ and HSOPSC (pteamwork scales (teamwork climate and teamwork within units) of the two instruments correlated strongly (safety r=0.72, pteamwork r=0.67, p<0.001). However, the means and per cent agreements for all scale scores and even seemingly similar item scores were significantly different. In addition, comparisons of scale score quartiles between the two instruments revealed that half of the NICUs fell into different quartiles when translating between the instruments. Large variation and opportunities for improvement in patient safety culture exist across NICUs. Important systematic differences exist between SAQ and HSOPSC such that these instruments should not be used interchangeably. Published by the BMJ Publishing Group Limited.

  2. Development of perceived instrumentality for mathematics, reading and science curricula

    Science.gov (United States)

    Garcia, Steve L.

    Perceptions of instrumentality (PI) are the connections one sees between a current activity and a future goal. With high PI, one is motivated to persist with quality effort because the current activity, even when difficult, is perceived as aligned with, and progress toward, the goal. Conversely, with low PI, one is motivated to relinquish effort in pursuit of other, more meaningful goals. In view of the alarming dropout rates in this country, it appears that PI research has much to offer in understanding students' motivations to stay in school and hence to become employed in their field of choice. Because academic achievement motivation can be affected by gender and ethnicity, particularly for specific components of the curriculum, and because curricular content varies across grade levels and school settings, this line of research offers significant potential for understanding and improving student outcomes. This research examined the development of PI among suburban 6th, 8th, 10th and 12th graders from a school district in the southwestern United States. Twelve hundred students completed a one-time paper and pencil survey measuring the perceived instrumentality of mathematics, literacy and science courses in terms of the students' occupational choices. MANOVA was used to determine factors that may affect students' overall PI and individual subject PI. Grade, gender, ethnicity, occupational choice, expectancy and value were the independent variables. A school setting variable was examined for effects on 12th graders. For the 8th through 12th grade sample, significant main effects were observed for grade, gender, minority status, occupational choice and expectancy on PI. Results show that PI is highest in the 6 th grade. Males reported higher Math PI than females. Females reported higher Reading PI and Science PI than males. Minority students reported lower overall PI and Science PI than non-minority students. Students who aspire to professional careers report the

    A positive and strong safety culture underpins effective learning from patient safety incidents in health care, including the community pharmacy (CP) setting. To build this culture, perceptions of safety climate must be measured with context-specific and reliable instruments. No pre-existing instruments were specifically designed or suitable for CP within Scotland. We therefore aimed to develop a psychometrically sound instrument to measure perceptions of safety climate within Scottish CPs. The first stage, development of a preliminary instrument, comprised three steps: (i) a literature review; (ii) focus group feedback; and (iii) content validation. The second stage, psychometric testing, consisted of three further steps: (iv) a pilot survey; (v) a survey of all CP staff within a single health board in NHS Scotland; and (vi) application of statistical methods, including principal components analysis and calculation of Cronbach's reliability coefficients, to derive the final instrument. The preliminary questionnaire was developed through a process of literature review and feedback. This questionnaire was completed by staff in 50 CPs from the 131 (38%) sampled. 250 completed questionnaires were suitable for analysis. Psychometric evaluation resulted in a 30-item instrument with five positively correlated safety climate factors: leadership, teamwork, safety systems, communication and working conditions. Reliability coefficients were satisfactory for the safety climate factors (α > 0.7) and overall (α = 0.93). The robust nature of the technical design and testing process has resulted in the development of an instrument with sufficient psychometric properties, which can be implemented in the community pharmacy setting in NHS Scotland. © 2014 John Wiley & Sons, Ltd.

    The current ability to predict very young children with sickle cell disease who are likely to have severe complications later in life permits accurate tailoring of therapy to match disease-related risks. A valid and reliable instrument is essential to accurately assess these children prior to referring them to therapies that are not without risk. This study was designed to develop a Sickle Cell Disease Assessment Instrument with two domains-high-risk identification and disease severity classification-and to evaluate instrument validity and reliability. Instrument development involved identification and definition of critical attributes, assignment of numerical values to critical attributes, and development of a scoring system. Content validity was measured using a panel of five experts in the field of sickle cell disease. Registered nurses using the equivalence approach determined interrater reliability and using test-retest design determined stability. Nurses are often the first persons to identify sickle cell patients that need additional intervention. This instrument will allow them to accurately and objectively assess their patients for high-risk indicators and disease severity classification.

    1998-01-01

    This paper describes the development and psychometric evaluation of an instrument designed to assess medical students' comfort with a range of sociocultural issues and intercultural experiences. Each survey item obliged students to reflect on their own sociocultural identities and academic status in relation to others', and to judge how comfortable they would be interacting across perceived boundaries based on sociocultural identity and academic status. More than 90% of University of Michigan first-year medical students (n=153) completed the survey just before classes began. Principal components analysis of the survey's 26 items identified 7 interpretable factors or subscales; the Cronbach alpha reliability coefficients for the 7 subscales and the total scale ranged from .73 to .92. T-tests were used to investigate differences in average ratings among student subgroups (based on gender and ethnicity). To assess the magnitude of the effect of the differences between groups, effect size was computed for each of the means comparisons. Psychometric analyses indicated that this survey was both reliable and valid for assessing students' cultural attitudes. Further, analyses by gender and ethnic subgroup identified meaningful ratings differences in men's and women's reported comfort levels. Our findings suggest that this instrument is useful for assessing students' openness to developing cultural awareness and competence. Educators at other medical schools may find this instrument useful as a needs assessment tool for planning educational programs designed to increase students' cultural competence.

  14. Mesospheric imaging Michelson interferometer instrument development and observations

    Science.gov (United States)

    Babcock, David D.

    This dissertation demonstrated the capability of the Mesospheric Imaging Michelson Interferometer (MIMI) instrument to passively measure wind velocities from Doppler-shifted atmospheric airglow emissions. The work consisted of two parts, (i) laboratory work focused on the measurement of simulated atmospheric winds with both Doppler-shifted visible and near-IR wavelengths and (ii) the development of a field instrument based on a lab prototype to investigate the potential of measuring Mesospheric winds from the ground. The primary component of the MIMI instrument was a custom built Michelson interferometer which was field widened, chromatically compensated, thermally compensated, and monolithic with no moving parts. The Michelson interferometer, used together with a novel four-point wind retrieval algorithm, provides simultaneous emission rate and wind velocity data over a single integration time. Simultaneously measuring the emission rate over the FOV and measuring wind velocity relative to the observer, of an air parcel containing an emitting chemical species, is a unique feature of the MIMI instrument. Eliminating sequential scanning of the Michelson to measure wind velocities (or being able to take a 'snapshot' of the atmosphere) and provide data on the emission rates and wind velocities, renders the instrument insensitive to scene changes over the integration time, which is an advantage over traditional scanning Michelson interferometers. Spectral lines from visible and near-IR sources were Doppler shifted in a controllable procedure to provide known velocities which were compared to the velocities measured by the interferometer. Wind simulations completed in the visible wavelength region retrieved velocities to within a standard deviation of +/-1ms-1. Wind simulations in the near-IR retrieved wind velocities to within a standard deviation of +/-2ms -1. These standard deviations are acceptable when compared to typical Mesospheric winds of 10 to 100ms-1 and when

    There is a strong need for portable radiometric instrumentation that can accurately confirm the presence of nuclear materials and allow isotopic analysis of radionuclides in the field. To fulfill this need we are developing a hand-held, non-cryogenic, low-power gamma- and x-ray measurement and analysis instrument that can both search and then accurately verify the presence of nuclear materials. We report on the use of cadmium zinc telluride detectors, signal processing electronics, and the new field-portable instrument based on the MicroNOMAD Multichannel Analyzer from EG&G ORTBC. We also describe the isotopic analysis that allows uranium enrichment measurements to be made accurately in the field.

    Full Text Available In order to assess relationships between perceptions of anonymity and behaviors, a context independent instrument is required for measuring the perceptions of anonymity held by individuals.  To date, no such measurement instrument exists that has been shown to be reliable and valid.  The authors employ a rigorous design methodology to develop, test, and substantiate a reliable and valid instrument for measuring perceptions of anonymity across different contexts. The PA measure presented is a five item Likert scale designed to measure perceptions of anonymity across multiple contexts. Results from two separate EFA pilot tests (n=61 and n=60, a test-retest, and a CFA final test (n=292 indicate that the PA measure has good internal consistency reliability (a=.82, test-retest reliability, factorial validity, and a single factor structure. DOI: 10.2458/azu_jmmss.v5i1.18305

    2007-01-01

    This slide presentation reviews the development of smart payloads instruments systems with high data rates. On-board computation has become a bottleneck for advanced science instrument and engineering capabilities. In order to improve the computation capability on board, smart payloads have been proposed. A smart payload is a Localized instrument, that can offload the flight processor of extensive computing cycles, simplify the interfaces, and minimize the dependency of the instrument on the flight system. This has been proposed for the Mars mission, Mars Atmospheric Trace Molecule Spectroscopy (MATMOS). The design of this system is discussed; the features of the Virtex-4, are discussed, and the technical approach is reviewed. The proposed Hybrid Field Programmable Gate Array (FPGA) technology has been shown to deliver breakthrough performance by tightly coupling hardware and software. Smart Payload designs for instruments such as MATMOS can meet science data return requirements with more competitive use of available on-board resources and can provide algorithm acceleration in hardware leading to implementation of better (more advanced) algorithms in on-board systems for improved science data return

    Quinn, Jack; Christensen, John L. (Technical Monitor)

    2001-01-01

    The Electron Drift Instrument (EDI) is a new technique for measuring electric fields in space by detecting the effect on weak beams of test electrons. This U.S. portions of the technique, flight hardware, and flight software were developed for the Cluster mission under this contract. Dr. Goetz Paschmann of the Max Planck Institute in Garching, Germany, was the Principle Investigator for Cluster EDI. Hardware for Cluster was developed in the U.S. at the University of New Hampshire, Lockheed Palo Alto Research Laboratory, and University of California, San Diego. The Cluster satellites carrying the original EDI instruments were lost in the catastrophic launch failure of first flight of the Arianne-V rocket in 1996. Following that loss, NASA and ESA approved a rebuild of the Cluster mission, for which all four satellites were successfully launched in the Summer of 2000. Limited operations of EDI were also obtained on the Equator-S satellite, which was launched in December, 1997. A satellite failure caused a loss of the Equator-S mission after only 5 months, but these operations were extremely valuable in learning about the characteristics and operations of the complex EDI instrument. The Cluster mission, satellites, and instruments underwent an extensive on-orbit commissioning phase in the Fall of 2000, carrying over through January 2001. During this period all elements of the instruments were checked and careful measurements of inter-experiments interferences were made. EDI is currently working exceptionally well in orbit. Initial results verify that all aspects of the instrument are working as planned, and returning highly valuable scientific information. The first two papers describing EDI on-orbit results have been submitted for publication in April, 2001. The principles of the EDI technique, and its implementation on Cluster are described in two papers by Paschmann et al., attached as Appendices A and B.

    One goal of an undergraduate education in mathematics is to help students develop a productive disposition towards mathematics. A way of conceiving of this is as helping mathematical novices transition to more expert-like perceptions of mathematics. This conceptualization creates a need for a way to characterize students' perceptions of mathematics in authentic educational settings. This article presents a survey, the Mathematics Attitudes and Perceptions Survey (MAPS), designed to address this need. We present the development of the MAPS instrument and its validation on a large (N = 3411) set of student data. Results from various MAPS implementations corroborate results from analogous instruments in other STEM disciplines. We present these results and highlight some in particular: MAPS scores correlate with course grades; students tend to move away from expert-like orientations over a semester or year of taking a mathematics course; and interactive-engagement type lectures have less of a negative impact, but no positive impact, on students' overall orientations than traditional lecturing. We include the MAPS instrument in this article and suggest ways in which it may deepen our understanding of undergraduate mathematics education.

    'Serious leisure' cycling has developed as a reinterpretation of the traditional form of the sport. This short term, informal, unstructured and unconventional conceptualisation represents a challenge to participant numbers in the mainstream sport. The purpose of this study was twofold: (i) to ascertain the cultural, subcultural and ecological factors of participation in this new conceptualised form enabling clubs, associations and governments to a deeper understanding about participants practices and (ii) as an ongoing validation to previous qualitative work (see O'Connor and Brown, 2005). This study reports on the development and psychometric properties (principal components analysis, confirmatory factor analysis) of the Cyclists' Motivation Instrument. Four hundred and twenty two cyclists (371 males, 51 females) who were registered members of the state competitive cycling body completed a fifty-one item instrument. Five factors were identified: social, embodiment, self-presentation, exploring environments and physical health outcomes and these accounted for 47.2% of the variance. Factor alpha coefficients ranged from .63 to .88, overall scale reliability was .92, suggesting moderate to high reliability for each of the factors and the overall scale. Key pointsSerious leisure' cyclists' are fitness seeking enthusiasts that attach different meanings to the act of cycling and participate in different physical, social and natural environments in comparison to other cyclists.This study develops and validates a new tool, the Cyclists Motivation Instrument (CMI), and presents the initial psychometric properties (principal components analysis, confirmatory factor analysis).FIVE FACTORS WERE IDENTIFIED: social, embodiment, self-presentation, exploring environments and physical health outcomes.The scale demonstrates adequate reliability (total scale, α = 0.92) and validity.

    The Mediterranean diet (MD) can reduce chronic disease risk and is a recommended diet for prevention and management of diabetes. Adherence to the MD in the southeast United States where obesity and diabetes are highly prevalent is unknown. The purpose of the present study was to: 1) construct a survey instrument relevant to the general population integrating both MD related nutrition knowledge and adherence questions from previously validated instruments, and 2) assess MD related nutrition knowledge and adherence in a sample population in the southest United States. Adherance was assessed using the validated short MD Adherence Screener (MEDAS). A MD nutrition knowledge (MDNK) questionnaire was developed from previously validated general nutrition knowledge questionnaires and was validated using 127 university students enrolled in three courses with varying levels of nutrition education. Cronbach's α for internal validity of MDNK was acceptable for a short questionnaire (0.653). Test-retest reliability was established (r = 0.853). Field validation of the three-part survey instrument (MEDAS, MDNK and demographic questions) was subsequently performed in 230 adults shopping at supermarkets and farmers markets in eastern Alabama. Total MDNK and MEDAS scores were significantly higher in students with formal nutrition education and in patrons of farmers markets. Greater MD adherence, assessed by dividing MEDAS scores into thirds, was found with increasing formal nutrition education in university students (p = 0.002) and in farmers market participants (p < 0.001). There was a weak but significant association between MDNK and MEDAS scores within university students and participants in the field. Together, the MDNK-MEDAS survey instrument is an effective tool for assessing baseline knowledge and adherence and can be used to target nutritional interventions to improve MD adherence for prevention and management of diabetes and other chronic disease.

    1991-01-01

    The U.S. Geological Survey is acquiring a new generation of field computers and communications software to support hydrologic data-collection at field locations. The new computer hardware and software mark the beginning of the Survey's transition from the use of electromechanical devices and paper tapes to electronic microprocessor-based instrumentation. Software is being developed for these microprocessors to facilitate the collection, conversion, and entry of data into the Survey's National Water Information System. The new automated data-collection process features several microprocessor-controlled sensors connected to a serial digital multidrop line operated by an electronic data recorder. Data are acquired from the sensors in response to instructions programmed into the data recorder by the user through small portable lap-top or hand-held computers. The portable computers, called personal field computers, also are used to extract data from the electronic recorders for transport by courier to the office computers. The Survey's alternative to manual or courier retrieval is the use of microprocessor-based remote telemetry stations. Plans have been developed to enhance the Survey's use of the Geostationary Operational Environmental Satellite telemetry by replacing the present network of direct-readout ground stations with less expensive units. Plans also provide for computer software that will support other forms of telemetry such as telephone or land-based radio.

    Full Text Available Orientation: The interference between work and personal life is a central issue in the 21st century as employees attempt to balance or integrate their involvement in multiple social roles.Research purpose: The purpose of this study was to, (1 develop new items for a more comprehensive work−nonwork interference instrument, (2 evaluate the newly developed items to retain those items that accurately capture the different dimensions and (3 eliminate undesirable items from the different subscales in the instrument.Motivation for the study: Although the interaction between work and personal life has received extensive attention in the work−family fields of research, various theoretical, empirical and measurement issues need to be addressed.Research design, approach and method: A cross-sectional survey design was used to collect the data.Main findings: Initially, 89 items were developed. During the pilot study among mineworkers (n = 245, 41 poor items were eliminated on the basis of descriptive statistics, inter-item correlations, item-total correlations and the qualitative investigation of items highly redundant in terms of wording. Thereafter, the instrument (48 items was administered to 366 support and academic personnel at a tertiary institution. Using Rasch analyses and item correlations, 18 additional items were eliminated, resulting in a 30-item instrument (15 items were retained to measure work-nonwork interference and 15 items to measure nonwork-work interference.Practical/managerial implications: A major theoretical limitation to the measurement of work−family interference relates to the dimensionality and inconsistent measurement of the directionality of interference.Contribution/value-add: With the development of this new instrument, several of the theoretical and measurement limitations voiced by previous researchers have been addressed, providing this instrument with distinct advantages over previous work−family instruments.

    The project had three major aims: improvement of technology for high-speed cell and chromosome sorting; the use of such instrumentation in genome analysis; applying the principles developed and the lessons learned to automated processes for the genome program. The work was a continuation of studies that were started at the Lawrence Livermore National Laboratory before the PI moved to the University of Washington. At Livermore, a high-speed sorter for the selection of human chromosomes was built. The instrument incorporated Livermore`s advanced sorter technology. The engineering focused on improving robustness and reliability so that the full potential of high-speed sorting would become available to the biological research laboratory. The new instrument, dubbed MoFlo for modular flow cytometer, proved to be a very practical and efficient tool during the chromosome isolation phase of the gene-library project. Its reliability and ease of operation exceeded that of the commercial instruments. The technology was licensed to two companies.

    This paper describes the development of the Deliberate Practice in Nursing Questionnaire (DPNQ) and the reliability and validity characteristics of the instrument. A cross-sectional, descriptive study assessed the DPNQ in a sample of critical care registered nurses (RN). It was conducted at one large Midwestern teaching hospital. A medical intensive care unit (ICU), a surgical ICU, and a trauma/burn ICU participated. Instrument construction involved item development based on a literature review, an existing deliberate practice questionnaire and existing parameters of deliberate practice in nursing. Content reliability and validity were established by expert panel review and survey testing. Probit analysis of survey data was used to develop a composite score for the DPNQ. Expert panel review revealed an inter-rater agreement (80% reliability) of .92-.96 and a content validity index of 0.94. The final DPNQ consists of 24 items with six subcategories and a composite score of 96. Cronbach's alpha coefficient for the DPNQ in this study was .660 (standardized, .703). The instrument was further validated with the Nurse Competence Scale. Deliberate practice was significantly, positively correlated with competence (rs=.366, p=001). Findings from the expert panel provided guidance for development and revision of the DPNQ. Survey testing of the instrument revealed a promising measure of deliberate practice with good reliability and validity characteristics. Identification of a relationship between deliberate practice and competence confirms existing evidence in other domains, providing further validation. Understanding deliberate practice provides a unique way to examine nursing expertise. Copyright © 2015 Elsevier Inc. All rights reserved.

    This project seeks to bring about a more effective use of nuclear instruments in medical applications of radionuclides in developing countries by facilitating selection of appropriate applications, by stimulating the design of instruments capable of performing these applications satisfactorily under the conditions prevailing, and by encouraging improved maintenance. A pilot cost-effectiveness analysis of nuclear medicine applications has been completed, suggesting two topics for further investigation and demonstrating that such analyses can yield useful insights. In the realm of instrument design, we have further developed our prototype well scintillation counter, provided three such instruments for tests in the field, and encouraged its production by others. In addition, we have examined design issues for liquid scintillation counters, radiorespirometry counting devices, whole-body counters, and electrical power supplies. We have completed a survey of maintenance in 8 countries in Southeast Asia and are analyzing the results. Preparations are underway for surveys in three further regions.

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.

Despite this development, because of the small catchment area and the 3D laser scanner's sophisticated technologies, the cost of these instruments is very high and beyond the reach of most operators in the field of cultural heritages. This is the reason why they have appeared low-cost technologies or even free, allowing anyone to approach the issues of acquisition and 3D modeling, providing tools that allow to create three-dimensional models in a simple and economical way.

    The Advanced Camera for Surveys (ACS), a third-generation instrument, was installed in the Hubble Space Telescope during Servicing Mission 3B, on March 7, 2002. Its primary purpose was to increase HST imaging discovery efficiency by about a factor of 10, with a combination of detector area and quantum efficiency that surpasses previous instruments. ACS has three independent cameras that have provided wide-field, high resolution, and ultraviolet imaging capabilities respectively, using a broad assortment of filters designed to address a large range of scientific goals. In addition, coronagraphic, polarimetric, and grism capabilities have made the ACS a versatile and powerful instrument. The ACS Instrument Handbook, which is maintained by the ACS Team at STScI, descr ibes the instrument properties, performance, operations, and calibration. It is the basic technical reference manual for the instrument, and should be used with other documents (listed in Table 1.1) for writing Phase I proposals, detailed Phase II programs, and for data analysis. (See Figure 1.1). In May 2009, Servicing Mission 4 (SM4) successfully restored the ACS Wide Field Camera (WFC) to regular service after its failure in January 2007. Unfortunately, the ACS High Resolution Camera (HRC) was not restored to operation during SM4, so it cannot be proposed for new observations. Nevertheless, this handbook retains description of the HRC to support analysis of archived observations. The ACS Solar Blind Channel (SBC) was unaffected by the January 2007 failure of WFC and HRC. The SBC has remained in steady operation, and was not serviced during SM4. It remains available for new observations.

    The Dark Energy Spectroscopic Instrument (DESI) will enable an ambitious redshift survey to probe dark energy by the baryon acoustic oscillation and redshift-space distortion methods. The same data set will serve numerous other goals in cosmology and astrophysics. Using a new 5000-fiber instrument and 8 square degree field of view at the Mayall telescope, the DESI survey plans to cover 14,000 square degrees and about 25 million high-redshift objects. The targets include 4M luminous red galaxies (redshift 0.4-1.0), 18M emission line galaxies (redshift 0.6-1.6), and 2.4M quasars, including 0.7M Lyman-alpha forest sight lines. With this, DESI can map the expansion history of the Universe to redshift 3, achieving unprecedented performance from the baryon acoustic oscillation method. We will describe the present state of the survey design and the cosmological forecasts for dark energy, inflation, and neutrino physics. We also give an update on the DESI Science Collaboration.

    The FASES experiments target the investigation of the stability of emulsions. The main objec-tives are the study of the surfactant adsorption at the liquid / liquid interfaces, the interaction of the droplets as well as the behaviour of the liquid film between nearby drops. Particular focus is given to the dynamic droplet evolution during emulsion destabilisation. The results of the experiments shall support development of methods for the modelling of droplet size distri-butions, which are important to many industries using stable emulsions like food production, cosmetics and pharmaceutics or unstable emulsions as required for applications in waste water treatment or crude oil recovery. The development of the experimental instrumentation was initiated in 2002. The flight instru-ment hardware development was started in 2004 and finally the flight unit was completed in 2009. Currently the final flight preparation is proceeding targeting a launch to the International Space Station (ISS) with Progress 39P in September 2010. The experiment setup of the instrument is accommodated in a box type insert called Experiment Container (EC), which will be installed in the Fluid Science Laboratory part of the European Columbus module of the ISS. The EC is composed of two diagnostics instruments for the investigation of transparent and opaque liquid emulsion. The transparent emulsions will be subject to the experiment called "Investigations on drop/drop interactions in Transparent Emulsions" (ITEM). The opaque emulsion samples will be studied in the experiment called "Investigations on concentrated or opaque Emulsions and on Phase Inversions" (EMPI). The thermal conditioning unit (TCU) allows performing homogeneous thermalization, tem-perature sweeps, emulsion preparation by stirrer, and optical diagnostics with a scanning mi-croscope. The objective of the instrument is the 3D reconstruction of the emulsion droplet distribution in the liquid matrix in terms of the droplet sizes

    Information systems provide nurses with a variety of resources to facilitate their work. Nurses' use of information systems changes the way they collect assessment data, and plan and implement patient care. However, a reliable and valid instrument for measuring nurse's use of information systems does not currently exist. This study examined the development and psychometric testing of a measure of nurses' information systems use, the Information Systems Use Instrument (ISUI). A random sample of 570 nurses working in hospitals, providing direct patient care and using at least one information system completed the study questionnaire. The internal consistency reliability was .82. Exploratory factor analysis, using principal components extraction and varimax rotation, revealed that all seven items loaded cleanly and strongly on a single factor. The ISUI showed sufficient evidence for its psychometric properties to encourage its use.

  4. Understanding nature's particle accelerators using high energy gamma-ray survey instruments

    Abeysekara, Anushka Udara

    Nature's particle accelerators, such as Pulsars, Pulsar Wind Nebulae, Active Galactic Nuclei and Supernova Remnants accelerate charged particles to very high energies that then produce high energy photons. The particle acceleration mechanisms and the high energy photon emission mechanisms are poorly understood phenomena. These mechanisms can be understood either by studying individual sources in detail or, alternatively, using the collective properties of a sample of sources. Recent development of GeV survey instruments, such as Fermi-LAT, and TeV survey instruments, such as Milagro, provides a large sample of high energy gamma-ray flux measurements from galactic and extra-galactic sources. In this thesis I provide constraints on GeV and TeV radiation mechanisms using the X-ray-TeV correlations and GeV-TeV correlations. My data sample was obtained from three targeted searches for extragalactic sources and two targeted search for galactic sources, using the existing Milagro sky maps. The first extragalactic candidate list consists of Fermi-LAT GeV extragalactic sources, and the second extragalactic candidate list consists of TeVCat extragalactic sources that have been detected by Imaging Atmospheric Cerenkov Telescopes (IACTs). In both extragalactic candidate lists Markarian 421 was the only source detected by Milagro. A comparison between the Markarian 421 time-averaged flux, measured by Milagro, and the flux measurements of transient states, measured by IACTs, is discussed. The third extragalactic candidate list is a list of potential TeV emitting BL Lac candidates that was synthesized using X-ray observations of BL Lac objects and a Synchrotron Self-Compton model. Milagro's sensitivity was not sufficient to detect any of those candidates. However, the 95% confidence flux upper limits of those sources were above the predicted flux. Therefore, these results provide evidence to conclude that the Synchrotron Self-Compton model for BL Lac objects is still a viable

    The possibility of the application of Surveying Biochemistry Light Instrument (SBLI) in the reaction system of starch with Mn3+was studied. The results showed: neither starch nor initiator(Mn3+) could produce light because no factor that could produce light existed in them. But starch could produce light when it was acted by Mn3 + and the intensity of light depended on the kind and concentration of starch, the amount of Mn3 +, the temperature and pH of the reaction system. In addition, the intensity of light decreased with the reaction time because of the gradual disappearance of starch free radicals.

    To report on the development of content and user feedback regarding the assessment process and utility of the workplace-based assessment instruments of the Pediatrics Milestones Assessment Pilot (PMAP). One multisource feedback instrument and two structured clinical observation instruments were developed and refined by experts in pediatrics and assessment to provide evidence for nine competencies based on the Pediatrics Milestones (PMs) and chosen to inform residency program faculty decisions about learners' readiness to serve as pediatric interns in the inpatient setting. During the 2012-2013 PMAP study, 18 U.S. pediatric residency programs enrolled interns and subinterns. Faculty, residents, nurses, and other observers used the instruments to assess learner performance through direct observation during a one-month rotation. At the end of the rotation, data were aggregated for each learner, milestone levels were assigned using a milestone classification form, and feedback was provided to learners. Learners and site leads were surveyed and/or interviewed about their experience as participants. Across the sites, 2,338 instruments assessing 239 learners were completed by 630 unique observers. Regarding end-of-rotation feedback, 93% of learners (128/137) agreed the assessments and feedback "helped me understand how those with whom I work perceive my performance," and 85% (117/137) agreed they were "useful for constructing future goals or identifying a developmental path." Site leads identified several benefits and challenges to the assessment process. PM-based instruments used in workplace-based assessment provide a meaningful and acceptable approach to collecting evidence of learner competency development. Learners valued feedback provided by PM-based assessment.

    Full Text Available The study combined qualitative approaches with quantitative research design to come up with a survey instrument called Culture-Sensitive Physics Learning Environment Survey (CS-PLES.This survey instrument is intended to extract the learners’ beliefs and expectations on the integration of culture and language in the teaching and learning process of physics concepts. Significant contribution of the instrument can be traced to establishing and defining the constructs and categories on how curriculum localization and context-based science learning can be developed aligned with students’ expectations and beliefs. The development process employed non-conventional processes adopted from literature which included pilot study to identify pre-deterministic constructs and specific categories for the items to be included in the survey. Data analysis included descriptive statistics and factor analysis to establish the categories or constructs of the survey instruments. Reliability measures of the instrument and its respective constructs were established for standardization. These categories were intended to aid researchers for an in-depth analysis when the instrument is administered for its purpose. The raw statistical categories were qualitatively paralleled with the pre-deterministic constructs to establish congruence of the survey tool to Instructional Congruence Framework (ICF.

    Chronic interpersonal traumata systematically result in psychological impairments referred to as complex post-traumatic stress disorder (cPTSD or DESNOS). This diagnosis will be newly established in the ICD-11 system. However, there is need for diagnostic instruments to assess cPTSD. The aim was to develop a screening form to identify patients at risk for cPTSD. The Screening for complex PTSD (SkPTBS) tests a) experience of potential traumatic events, b) related influential features and risk factors, and c) symptoms of cPTSD. 325 patients (mean age 51.5±8.7 years; 62.1% female) filled out the screening instrument at the beginning of their inpatient psychotherapy. The primary criterion for testing SkPTBS validity was the diagnosis of complex PTSD at the end of the inpatient treatment. The proportion of patients with cPTSD was 8.9% (n=29). SkPTBS items were selective, and the scale showed very good reliability (α=0.91). Factor analysis revealed a one-dimensional structure. SkPTBS total values predicted having cPTSD diagnosis and were correlated with global symptom severity (SCL-90-R) and depressive symptoms (BDI-II). There is evidence for high clinical utility of SkPTBS. A revised version was developed. © Georg Thieme Verlag KG Stuttgart · New York.

    Allen, V. R.

    1982-08-01

    Dynamic mechanical analysis instrumentation was used for the development of specific test methodology in the determination of engineering parameters of selected materials, esp. plastics and elastomers, over a broad range of temperature with selected environment. The methodology for routine procedures was established with specific attention given to sample geometry, sample size, and mounting techniques. The basic software of the duPont 1090 thermal analyzer was used for data reduction which simplify the theoretical interpretation. Clamps were developed which allowed 'relative' damping during the cure cycle to be measured for the fiber-glass supported resin. The correlation of fracture energy 'toughness' (or impact strength) with the low temperature (glassy) relaxation responses for a 'rubber-modified' epoxy system was negative in result because the low-temperature dispersion mode (-80 C) of the modifier coincided with that of the epoxy matrix, making quantitative comparison unrealistic.

    2011-01-01

    Hypersonic Inflatable Aerodynamic Decelerator (HIAD) technology is currently being considered for multiple atmospheric entry applications as the limitations of traditional entry vehicles have been reached. The Inflatable Re-entry Vehicle Experiment (IRVE) has successfully demonstrated this technology as a viable candidate with a 3.0 m diameter vehicle sub-orbital flight. To further this technology, large scale HIADs (6.0 8.5 m) must be developed and tested. To characterize the performance of large scale HIAD technology new instrumentation concepts must be developed to accommodate the flexible nature inflatable aeroshell. Many of the concepts that are under consideration for the HIAD FY12 subsonic wind tunnel test series are discussed below.

    To measure the parameter of job satisfaction among anesthesiologists. Survey instrument. Academic anesthesiology departments in the United States. 320 anesthesiologists who attended the annual meeting of the ASA in 2009 (95% response rate). The anonymous 50-item survey collected information on 26 independent demographic variables and 24 dependent ranked variables of career satisfaction among practicing anesthesiologists. Mean survey scores were calculated for each demographic variable and tested for statistically significant differences by analysis of variance. Questions within each domain that were internally consistent with each other within domains were identified by Cronbach's alpha ≥ 0.7. P-values ≤ 0.05 were considered statistically significant. Cronbach's alpha analysis showed strong internal consistency for 10 dependent outcome questions in the practice factor-related domain (α = 0.72), 6 dependent outcome questions in the peer factor-related domain (α = 0.71), and 8 dependent outcome questions in the personal factor-related domain (α = 0.81). Although age was not a variable, full-time status, early satisfaction within the first 5 years of practice, working with respected peers, and personal choice factors were all significantly associated with anesthesiologist job satisfaction. Improvements in factors related to job satisfaction among anesthesiologists may lead to higher early and current career satisfaction. Copyright © 2013 Elsevier Inc. All rights reserved.

    Many DOE applications would significantly benefit from the availability of robust and convenient instrumentation for trace-level actinide monitoring and analysis. This project focuses on developing new instrumentation for on-line or at-line monitoring for actinides with isotopic analysis capability. In addition, analytical protocols for a novel concentration method for actinides are being investigated. These efforts focus on demonstrating these techniques using uranium. In addition to its value in the analytical laboratory, the combination of a simple concentration technique with a robust isotopic monitor could provide a powerful method for addressing a number of outstanding DOE needs. Potential applications include monitors for waste water and sewage treatment systems influent and effluent, and the ability to determine the isotopic content of transuranic species in low-activity waste fractions for waste classification and product acceptance. For example, the need for improved monitoring for uranium, plutonium, and americium in treatment plant influent is clearly identified in need RF-ER11. With some additional sample pretreatment, such technology could also impact materials characterization needs by providing on-site isotopic analyses in a system that is smaller and significantly less complex than inductively coupled plasma mass spectrometry (ICP-MS).

    The base floor of SANS was constructed by the 27 steel plates with horizontal flatness of {+-}0.5mm. That is for the two dimensional position sensitivity neutron detector(2D-PSD), which is operated in vacuum chamber, as moving smoothly. Concerned to the equipments, we designed and installed the inner-shielding of the PNS which will be used for research of magnetic structure and critical phenomena of the materials. In the development of experimental devices, we have designed and manufactured a beam-stop exchange unit and a detector carriage which are used for 2D-PSD. The detector carriage is to control the distance between sample and detector. The beam-stop exchange unit is to protect detector from exposure of direct neutron beam. Especially, many experimental devices or instruments such as high-resolution collimator, components for low temperature facility, multi-purpose vacuum chamber, etc. were made in domestic, it is worth meaningful in domestic availability and standardization for the neutron instrument component.

    Full Text Available Problem statement: Field machines contribute a major portion of the total cost of crop production. Proper selection and matching of farm machinery is essential in order to reduce the cost of crop production. Performance data for tractors and implements are, therefore, essential for farm machinery operators and manufacturers alike. The aim of this study was to develop and evaluate an instrumentation system for tractor and agricultural implements. Approach: An instrumentation system was developed and mounted on an MF 3090 tractor to measure and record data for the various performance parameters of the tractor and attached tillage implements. The system was designed to measure: drawbar pull, three-point linkage forces, rear and front wheel forces, PTO torque, ground speed, tillage depth, fuel consumption, engine speed and fluid temperatures. Results: The system performed well during the field operations and the results obtained showed that the accuracies of the transducers were acceptable. The wheel torque and weight transducers measured the torque and forces acting on the tractor wheels with high accuracy. The other transducers measured the vertical and the horizontal forces on mounted implements of categories II (40-100 hp and III (80-225 hp. The field tests showed significant increase in the draft with increases in the depth and speed. A general regression equation to predict draft of the implements was developed. Conclusion: The system was capable of measuring the draft of primary tillage implements on sandy loam soils at various speeds and depths with high accuracy. The data was recorded, displayed and analyzes simultaneously.

    Web-based application developers face a dizzying array of platforms, languages, frameworks and technical artifacts to choose from. We survey, classify, and compare technologies supporting Web application development. The classification is based on (1) foundational technologies; (2)integration with other information sources; and (3) dynamic content generation. We further survey and classify software engineering techniques and tools that have been adopted from traditional programming into Web programming. We conclude that, although the infrastructure problems of the Web have largely been solved, the cacophony of technologies for Web-based applications reflects the lack of a solid model tailored for this domain.

    In this report automatic startup technology and dynamic alarm processing technology are developed. We designed an automatic control system had four modes and six break points. The four modes are heating mode I, heating mode II, heating mode III and critical mode. The six break points are RHR isolation and pressurizer bubble generation, P-6, critical conformation and another three break points for the start point of each mode from heating mode II to critical mode. We defined control variables and components at each mode and developed control algorithms. The conceptual design for automatic startup system configuration and interface with test facility was developed. These results will be used for detail design and software implementation in the project of next year. For development of dynamic alarm processing technology, necessary techniques were selected according to the survey on current development activities and the analysis on design documents. Alarm operating procedures were studied for obtaining casual relationships among alarms and part of a preliminary prototype was implemented in this first year using the results of the analysis including various techniques studied during the survey and analysis stage. 70 figs, 7 tabs, 77 refs.

    This article focuses on the usefulness of going beyond the concept of resistance to change and capitalizing on the use of a model that includes positivity and acceptance of change. We first discuss the theoretical background of this new construct in the work and organizational fields and then evaluate the psychometric properties of a new measure for assessing acceptance of change. The results of exploratory factor analysis indicated a factor structure with five principal dimensions; besides confirmatory factor analysis (CFA) goodness of fit indices indicated a good fit of the model to the data. All the dimensions showed good values of internal consistency. The results of the present study indicate that the Acceptance of Change Scale (ACS) is a brief and easily administered instrument with good psychometric properties that can promote the development of clients' strengths and the growth of a sense of Self, thereby helping them choose their own way without losing any opportunities in their lives and their work.

    2011-12-01

    The aim of the present work is the development of ground-based hyperspectral systems capable of collecting continuous and long-term hyperspectral measurements of the Earth-surface. The development of such instruments includes the optical design, the development of the data acquisition (Auto3S) and processing software as well as the definition of the calibration procedures. In particular an in-field calibration methodologie based on the comparison between field spectra and data modeled using Radiative Transfer (RT) approach has been proposed to regularly upgrade instrument calibration coefficients. Two different automatic spectrometric systems have been developed: the HyperSpectral Irradiometer (HSI) [Meroni et al., 2011] and the Multiplexer Radiometer Irradiometer (MRI) [Cogliati, 2011]. Both instruments are able to continuously measure: sun incoming irradiance (ETOT) and irradiance (ES, HSI)/radiance (LS, MRI) upwelling from the investigated surface. Both instruments employ two Ocean Optics HR4000 spectrometers sharing the same optical signal that allow to simultaneously collect "fine" (1 nm Full Width at Half Maximum, FWHM) spectra in the 400-1000 nm rangeand "ultra-fine" (0.1 nm FWHM) spectra within the 700-800 nm. The collected optical data allow to estimate biochemical/structural properties of vegetation (e.g. NDVI) as well as its photosynthetic efficiency through the Photochemical Reflectance Index (PRI) and the analysis of sun-induced chlorophyll Fluorescence in the O2-A Fraunhofer line (F@760). The automatic instruments were operated in coordination with eddy covariance flux tower measurements of carbon exchange in the framework of several field campaigns: HSI was employed in a subalpine pasture (2009-ongoing) (www.phenoalp.eu) while MRI was employed in 2009 in the Sen3Exp field survey promoted by the European Space Agency as consolidation study to the future mission Sentinel-3. Results show that the proposed instruments succeeded in collecting continuous

    To develop and test an instrument to assess physical function for Social Security Administration (SSA) disability programs, the SSA-Physical Function (SSA-PF) instrument. Item response theory (IRT) analyses were used to (1) create a calibrated item bank for each of the factors identified in prior factor analyses, (2) assess the fit of the items within each scale, (3) develop separate computer-adaptive testing (CAT) instruments for each scale, and (4) conduct initial psychometric testing. Cross-sectional data collection; IRT analyses; CAT simulation. Telephone and Internet survey. Two samples: SSA claimants (n=1017) and adults from the U.S. general population (n=999). None. Model fit statistics, correlation, and reliability coefficients. IRT analyses resulted in 5 unidimensional SSA-PF scales: Changing & Maintaining Body Position, Whole Body Mobility, Upper Body Function, Upper Extremity Fine Motor, and Wheelchair Mobility for a total of 102 items. High CAT accuracy was demonstrated by strong correlations between simulated CAT scores and those from the full item banks. On comparing the simulated CATs with the full item banks, very little loss of reliability or precision was noted, except at the lower and upper ranges of each scale. No difference in response patterns by age or sex was noted. The distributions of claimant scores were shifted to the lower end of each scale compared with those of a sample of U.S. adults. The SSA-PF instrument contributes important new methodology for measuring the physical function of adults applying to the SSA disability programs. Initial evaluation revealed that the SSA-PF instrument achieved considerable breadth of coverage in each content domain and demonstrated noteworthy psychometric properties.

    Johnson, William R.; Hook, Simon J.; Foote, Marc; Eng, Bjorn T.; Jau, Bruno

    2011-01-01

    The Jet Propulsion Laboratory is currently developing an end-to-end instrument which will provide a proof of concept prototype vehicle for a high data rate, multi-channel, thermal instrument in support of the Hyperspectral Infrared Imager (HyspIRI)-Thermal Infrared (TIR) space mission. HyspIRI mission was recommended by the National Research Council Decadal Survey (DS). The HyspIRI mission includes a visible shortwave infrared (SWIR) pushboom spectrometer and a multispectral whiskbroom thermal infrared (TIR) imager. The prototype testbed instrument addressed in this effort will only support the TIR. Data from the HyspIRI mission will be used to address key science questions related to the Solid Earth and Carbon Cycle and Ecosystems focus areas of the NASA Science Mission Directorate. Current designs for the HyspIRI-TIR space borne imager utilize eight spectral bands delineated with filters. The system will have 60m ground resolution, 200mK NEDT, 0.5C absolute temperature resolution with a 5-day repeat from LEO orbit. The prototype instrument will use mercury cadmium telluride (MCT) technology at the focal plane array in time delay integration mode. A custom read out integrated circuit (ROIC) will provide the high speed readout hence high data rates needed for the 5 day repeat. The current HyspIRI requirements dictate a ground knowledge measurement of 30m, so the prototype instrument will tackle this problem with a newly developed interferometeric metrology system. This will provide an absolute measurement of the scanning mirror to an order of magnitude better than conventional optical encoders. This will minimize the reliance on ground control points hence minimizing postprocessing (e.g. geo-rectification computations).

    The Gaia SpectroPhotometric Standard Stars (SPSS) survey started in 2006, it was awarded almost 450 observing nights, and accumulated almost 100,000 raw data frames, with both photometric and spectroscopic observations. Such large observational effort requires careful, homogeneous, and automated data reduction and quality control procedures. In this paper, we quantitatively evaluate instrumental effects that might have a significant (i.e.,$\\geq$1%) impact on the Gaia SPSS flux calibration. The measurements involve six different instruments, monitored over the eight years of observations dedicated to the Gaia flux standards campaigns: DOLORES@TNG in La Palma, EFOSC2@NTT and ROSS@REM in La Silla, CAFOS@2.2m in Calar Alto, BFOSC@Cassini in Loiano, and LaRuca@1.5m in San Pedro Martir. We examine and quantitatively evaluate the following effects: CCD linearity and shutter times, calibration frames stability, lamp flexures, second order contamination, light polarization, and fringing. We present methods to correct ...

    Questionnaires for the assessment of knowledge and self-perception can be useful to diagnose what a dentist knows about management and administration. The aim of the present study was to create and validate the Dental Management Survey Brazil (DMS-BR) scale, based on meetings with experts in the field. After having elaborated the first version, 10 audits were performed in dental offices in order to produce the final version, which included nine dimensions: location, patient, finance, marketing, competition, quality, staff, career, and productivity. The accuracy of the instrument was measured by intrarater and interrater reliability. In the validation phase, 247 Brazilian dentists answered a web-based questionnaire. The data were processed using Stata 13.0 and the significance level was set at 95%. The instrument had intrarater and interrater reliability (ICC-0.93 and 0.94). The overall average of respondents for the DMS-BR scale was 3.77 (SD = 0.45). Skewness and kurtosis were below absolute values 3 and 7, respectively. Internal validity measured by Cronbach's alpha was 0.925 and the correlation of each dimension with the final result of the DMS-BR ranged between 0.606 and 0.810. Correlation with the job satisfaction scale was 0.661. The SEM data ranged between 0.80 and 0.56. The questionnaire presented satisfactory indicators of dentists' self-perception about management and administration activities.

    NESSI: the New Mexico Tech Extrasolar Spectroscopic Survey Instrument is a ground-based multi-object spectrograph that operates in the near-infrared. It will be installed on one of the Nasmyth ports of the Magdalena Ridge Observatory (MRO) 2.4-meter Telescope sited in the Magdalena Mountains, about 48 km west of Socorro-NM. NESSI operates stationary to the telescope fork so as not to produce differential flexure between internal opto-mechanical components during or between observations. An appropriate mechanical design allows the instrument alignment to be highly repeatable and stable for both short and long observation timescales, within a wide-range of temperature variation. NESSI is optically composed of a field lens, a field de-rotator, re-imaging optics, an auto-guider and a Dewar spectrograph that operates at LN2 temperature. In this paper we report on NESSI's detailed mechanical and opto-mechanical design, and the planning for mechanical construction, assembly, integration and verification.

    2009-12-01

    This contribution will describe the initial stages of a new ASTID-funded research program initiated in Fall 2009 aimed at lab-on-a-chip system development for astrobiological investigations on Titan. This technology development builds off related work at JPL and Berkeley [1-3] on the ultrasensitive compositional and chiral analysis of amino acids on Mars in order to search for signatures of past or present life. The Mars-focused instrument system utilizes a microcapillary electrophoresis (μCE) system integrated with on-chip perfluoropolyether (PFPE) membrane valves and pumps for automated liquid sample handling, on-chip derivitization of samples with fluorescent tags, dilution, and mixing with standards for data calibration. It utilizes a four-layer wafer stack design with CE channels patterned in glass, along with a PFPE membrane, a pneumatic manifold layer, and a fluidic bus layer. Three pneumatically driven on-chip diaphragm valves placed in series are used to peristaltically pump reagents, buffers, and samples to and from capillary electrophoresis electrode well positions. Electrophoretic separation occurs in the all-glass channels near the base of the structure. The Titan specific lab-on-a-chip system under development here focuses its attention on the unique organic chemistry of Titan. In order to chromatographically separate mixtures of neutral organics such as polycyclic aromatic hydrocarbons (PAHs), the Titan-specific microfluidic platform utilizes the related technique of microcapillary electrochromatography (μCEC). This technique differs from conventional μCE in that microchannels are filled with a porous stationary phase that presents surfaces upon which analyte species can adsorb/desorb. It is this additional surface interaction that enables separations of species critical to the understanding of the astrobiological potential of Titan that are not readily separated by the μCE technique. We have developed two different approaches for the integration

    Full Text Available Introduction: Although nursing students spend a large part of their learning period in the clinical environment, clinical learning has not been perceived by its nature yet. To develop an instrument to measure effective factors on clinical learning in nursing students. Methods: This is a mixed methods study performed in 2 steps. First, the researchers defined “clinical learning” in nursing students through qualitative content analysis and designed items of the questionnaire based on semi-structured individual interviews with nursing students. Then, as the second step, psychometric properties of the questionnaire were evaluated using the face validity, content validity, construct validity, and internal consistency evaluated on 227 students from fourth or higher semesters. All the interviews were recorded and transcribed, and then, they were analyzed using Max Qualitative Data Analysis and all of qualitative data were analyzed using SPSS 14. Results: To do the study, we constructed the preliminary questionnaire containing 102 expressions. After determination of face and content validities by qualitative and quantitative approaches, the expressions of the questionnaire were reduced to 45. To determine the construct validity, exploratory factor analysis was applied. The results indicated that the maximum variance percentage (40.55% was defined by the first 3 factors while the rest of the total variance percentage (59.45% was determined by the other 42 factors. Results of exploratory factor analysis of this questionnaire indicated the presence of 3 instructor-staff, students, and educational related factors. Finally, 41 expressions were kept in 3 factor groups. The α-Cronbach coefficient (0.93 confirmed the high internal consistency of the questionnaire. Conclusion: Results indicated that the prepared questionnaire was an efficient instrument in the study of the effective factors on clinical learning as viewed by nursing students since it

    2015-08-01

    The work reports on the development of a Strontium Iodide Coded Aperture (SICA) instrument for use in space-based astrophysics, solar physics, and high-energy atmospheric physics. The Naval Research Laboratory is developing a prototype coded aperture imager that will consist of an 8 x 8 array of SrI2:Eu detectors, each read out by a silicon photomultiplier. The array would be used to demonstrate SrI2:Eu detector performance for space-based missions. Europium-doped strontium iodide (SrI2:Eu) detectors have recently become available, and the material is a strong candidate to replace existing detector technology currently used for space-based gamma-ray astrophysics research. The detectors have a typical energy resolution of 3.2% at 662 keV, a significant improvement over the 6.5% energy resolution of thallium-doped sodium iodide. With a density of 4.59 g/cm and a Zeff of 49, SrI2:Eu has a high efficiency for MeV gamma-ray detection. Coupling this with recent improvements in silicon photomultiplier technology (i.e., no bulky photomultiplier tubes) creates high-density, large-area, low-power detector arrays with good energy resolution. Also, the energy resolution of SrI2:Eu makes it ideal for use as the back plane of a Compton telescope.

  8. Development of Real-Time Coal Monitoring Instrument

    Rajan Gurjar, Ph.D.

    2010-06-17

    Relying on coal for energy requires optimizing the extraction of heat content from various blends of coal fuel and reducing harmful constituents and byproducts. Having a real-time measurement instrument provides relevant information about toxic constituents released in the atmosphere from burning coal and optimizes the performance of a power plant. A few commercial instruments exist and have been in operation for more than a decade. However, most of these instruments are based on radioactive sources and are bulky, expensive and time-consuming. The proposed instrument is based on the Laser Induced Breakdown Spectroscopy (LIBS). The advantage of LIBS is that it is a standoff instrument, does not require sample preparation and provides precise information about sample constituents.

    2005-04-01

    Full Text Available Abstract Background This paper describes the development of the Chinese Quality of Life Instrument (ChQOL which is a self-report health status instrument. Chinese Medicine relies very much on asking subjective feelings of patients in the process of diagnosis and monitoring of treatment. For thousands of years, Chinese Medicine practitioners have accumulated a good wealth of experiences in asking questions about health of their patients based on the concept of health in Chinese Medicine. These experiences were then transformed into questions for the ChQOL. It is believed that ChQOL can contribute to the existing Patient Report Outcome measures. This paper outlines the concept of health and disease in Traditional Chinese Medicine, the building of the conceptual framework of the ChQOL, the steps of drafting, selecting and validating the items, and the psychometric properties of the ChQOL. Methods The development of the ChQOL was based on the concept of health in Traditional Chinese Medicine with a theory driven approach. Based on the results of literature review, the research team developed an initial model of health which encompassed the concept of health in TCM. An expert panel was then invited to comment and give suggestions for improvement of the initial model. According to their suggestions, the model was refined and a set of initial items for the ChQOL was drafted. The refined model, together with the key domains, facets and initial items of the ChQOL were then mailed to a sample of about 100 Chinese medicine practitioners throughout Mainland China for their comments and advice. A revised set of items were developed for linguistic testing by a convenience sample consisting of both healthy people and people who attended Chinese Medicine treatment. After that, an item pool was developed for field-testing. Field test was conducted on a convenience sample of healthy and patient subjects to determine the construct validity and psychometric

    1997-11-01

    One of the major contributions to the improvement of spectral Doppler and colour flow imaging instruments has been the development of advanced signal-processing techniques made possible by increasing computing power. Model-based or parametric spectral estimators, time-frequency transforms, station-arising algorithms and spectral width correction techniques have been investigated as possible improvements on the FFT-based estimators currently used for real-time spectral estimation of Doppler signals. In colour flow imaging some improvement on velocity estimation accuracy has been achieved by the use of new algorithms but at the expense of increased computational complexity compared with the conventional autocorrelation method. Polynomial filters have been demonstrated to have some advantages over IIR filters for stationary echo cancellation. Several methods of velocity vector estimation to overcome the problem of angle dependence have been studied, including 2D feature tracking, two and three beam approaches and the use of spectral width in addition to mean frequency. 3D data acquisition and display and Doppler power imaging have also been investigated. The use of harmonic imaging, using the second harmonic generated by encapsulated bubble contrast media, seems promising particularly for imaging slow flow. Parallel image data acquisition using non-sequential scanning or broad beam transmission, followed by simultaneous reception along a number of beams, has been studied to speed up 'real-time' imaging.

    1993-01-01

    Inspecting bridges and monitoring scour during high flow can improve public transportation safety by providing early identification of scour and stream stability problems at bridges. Most bridge-inspection data are collected during low flow, when scour holes may have refilled. More than 25 percent of the States that responded to a questionnaire identified lack of adequate methodology and/or equipment as reasons for not collecting scour data during high-flow conditions. Therefore, the U.S. Geological Survey (USGS), in cooperation with the Federal Highway Administration, has begun to develop instrumentation for measuring scour that could be used by inspection and maintenance personnel during high-flow conditions. A variety of instruments and techniques for measuring scour were tested and evaluated in real-time bridge-scour data-collection studies by the USGS. In the National Scour study, fathometers were found to be superior to sounding weights and will be the primary bed-measuring instrument. The ability of low-cost fathometers and fish finders to locate the bed accurately is being evaluated. Simple and efficient methods for deploying the transducer during floods are also important for a successful measurement. The information and additional testing are being used to design new, portable scour-measuring systems.

    Full Text Available In most nuclear and radiological emergencies involving the release of radioactive materials to environment, it is important that data on the geographic distribution of potentially hazardous radioactive materials be quickly presented to the authorities. The mobile radiation detection system makes it possible to measure radioactive materials in the environment at random places because of its easy mobility from place to place. The purpose of the work is to develop a mobile radiation detection system to measure gamma exposure rate, radioactive material on the ground and airborne radioactive particulate in the environment quickly. In this work, we have developed a carborne survey equipment system consisting of three gamma ray detectors, one airbome radioactive particulate sampler, a GPS (Global Positioning System, meteorological sensors, a data acquisition system and an operation software. Performance of the carborne survey equipment has been successfully demonstrated to measure iodine and argon release from medical isotope production facility on Serpong in western Java, Indonesia.

The purpose of this study was to synthesize existing evidence regarding the impact of economic policies targeting obesity and its causal behaviours (diet, physical activity, and to make specific recommendations for the Canadian context. Methods Arksey and O'Malley's (2005 methodological framework for conducting scoping reviews was adopted for this study and this consisted of two phases: 1 a structured literature search and review, and 2 consultation with experts in the research field through a Delphi survey and an in-person expert panel meeting in April 2010. Results Two key findings from the scoping review included 1 consistent evidence that weight outcomes are responsive to food and beverage prices. The debate on the use of food taxes and subsidies to address obesity should now shift to how best to address practical issues in designing such policies; and 2 very few studies have examined the impact of economic instruments to promote physical activity and clear policy recommendations cannot be made at this time. Delphi survey findings emphasised the relatively modest impact any specific economic instrument would have on obesity independently. Based on empirical evidence and expert opinion, three recommendations were supported. First, to create and implement an effective health filter to review new and current agricultural polices to reduce the possibility that such policies have a deleterious impact on population rates of obesity. Second, to implement a caloric sweetened beverage tax. Third, to examine how to implement fruit and vegetable subsidies targeted at children and low income households. Conclusions In terms of economic interventions, shifting from empirical evidence to policy recommendation remains challenging. Overall, the evidence is not sufficiently strong to provide clear policy

    The points stimulated by output pulse of the electroacupuncture instrument are fixed, and this stimulation model makes Deqi sense of the distal point unable to reach the affected parts, only limiting around the point for most patients, so the therapeutic effects are influenced to a certain extent. From design, usage and other aspects, it is described that joint the output conducting wires to the acupuncture needles from the distal point to the proximal point in turn. When the output ports of the electroacupuncture instrument export the pulse wave one port by one port, the sense of Deqi of the patient propagates towards the affected area one point by one point. Finally, the sense of Deqi of the patient propagates and reaches to the affected area. The along-meridian treatment instrument overcomes the shortcomings of the existing electroacupuncture instrument, and obviously increases therapeutic effects.

    Although urinary incontinence is common in children, no validated pediatric instruments exist for measuring urinary incontinence symptoms and bother. We developed and validated a patient reported pediatric survey for urinary incontinence measurement. The Incontinence Symptom Index-Pediatric is an 11-item instrument comprising 2 domains, that is 1) impairment and 2) symptom severity, including subdomains for stress urinary incontinence, urge urinary incontinence, insensate urinary incontinence, nocturnal urinary incontinence and pad use. The survey was self-administered twice, 2 weeks apart, to boys and girls ages 11 to 17 years. Children completed the survey independently. Cases consisted of patients presenting to pediatric urology clinic with the chief complaint of urinary incontinence. Controls consisted of healthy children presenting for evaluation up at a general pediatric practice. Formal validation analysis was performed. A total of 19 subjects per arm completed at least 1 survey. Internal consistency was good with a Cronbach's alpha of 0.84 for the complete instrument. Item-scale correlations were greater than 0.60 for all except 1 item. Test-retest reliability was also good (r = 0.97, p <0.0001). Discriminative validity was good with a total severity scale score of 9.3 in wet children and 0.7 in controls (p <0.0001). Impairment scale scores differed by 2.2 points (p <0.0001). Mean scores differed significantly between subscales for all domains except pad use. The most dramatic difference was in the urge urinary incontinence domain, which differed by a mean of 3.6 points (p = 0.0002). This pilot study provides initial validation of a survey instrument for urinary incontinence in children and adolescents. This instrument can be used in children ages 11 to 17 years to objectively and reproducibly measure patient reported urinary incontinence.

  2. Design Considerations for a Launch Vehicle Development Flight Instrumentation System

    2011-01-01

    When embarking into the design of a new launch vehicle, engineering models of expected vehicle performance are always generated. While many models are well established and understood, some models contain design features that are only marginally known. Unfortunately, these analytical models produce uncertainties in design margins. The best way to answer these analytical issues is with vehicle level testing. The National Aeronautics and Space Administration respond to these uncertainties by using a vehicle level system called the Development Flight Instrumentation, or DFI. This DFI system can be simple to implement, with only a few measurements, or it may be a sophisticated system with hundreds of measurement and video, without a recording capability. From experience with DFI systems, DFI never goes away. The system is renamed and allowed to continue, in most cases. Proper system design can aid the transition to future data requirements. This paper will discuss design features that need to be considered when developing a DFI system for a launch vehicle. It will briefly review the data acquisition units, sensors, multiplexers and recorders, telemetry components and harnessing. It will present a reasonable set of requirements which should be implemented in the beginning of the program in order to start the design. It will discuss a simplistic DFI architecture that could be the basis for the next NASA launch vehicle. This will be followed by a discussion of the "experiences gained" from a past DFI system implementation, such as the very successful Ares I-X test flight. Application of these design considerations may not work for every situation, but they may direct a path toward success or at least make one pause and ask the right questions.

    We developed methods to monitor the status of Gyrfalcons in Alaska. Results of surveys and monitoring will be informative for resource managers and will be useful for studying potential changes in ecological communities of the high latitudes. We estimated that the probability of detecting a Gyrfalcon at an occupied nest site was between 64% and 87% depending on observer experience and aircraft type (fixed-wing or helicopter). The probability of detection is an important factor for estimating occupancy of nesting areas, and occupancy can be used as a metric for monitoring species' status. We conclude that surveys of nesting habitat to monitor occupancy during the breeding season are practical because of the high probability of seeing a Gyrfalcon from aircraft. Aerial surveys are effective for searching sample plots or index areas in the expanse of the Alaskan terrain. Furthermore, several species of cliff-nesting birds can be surveyed concurrently from aircraft. Occupancy estimation also can be applied using data from other field search methods (e.g., from boats) that have proven useful in Alaska. We believe a coordinated broad-scale, inter-agency, collaborative approach is necessary in Alaska. Monitoring can be facilitated by collating and archiving each set of results in a secure universal repository to allow for statewide meta-analysis.

    We found essential problems followed by digitalizing of instrumentation and control. A scheme is divided into hardware and software to resolve these problems. We have analyzed the hardware V and V methodologies about common mode failure, commercial grade dedication process and electromagnetic compatibility. We have developed several guidelines, the software classification guideline, the quality assurance handbook for the software in digital I and C, the software V and V planning guideline, and the software safety guideline. And then, we have established the integrated environment for the safety-critical software based on the Computer Aided Software Engineering (CASE) tools. We have also surveyed a trend and application case of test facility for establishment of functional requirements. Input/output interface which connects among the host computer and developed target and panel are designed and manufactured using UXI bus. The developed functional test facility is used for test and validate the automatic start-up intelligent control system, the dynamic alarm system, the accident identification system using hidden Markov model, and the intelligent logic tracking system. The result of evaluation of the above systems shows the functional test facility performance is sufficient in normal operating and transient conditions. (author). 24 tabs., 59 figs.

  5. Development of instrumentation for guided long-hole drilling

    Energy Technology Data Exchange (ETDEWEB)

    1990-01-01

    Guided long-hole drilling (GLHD) is a relatively new exploration technique which has an important role to play in minimising geological risks in coal mining. The technique requires the use of survey probes to determine the trajectory of an in-seam drilled borehole and its position with respect to the coal seam boundaries. Prototype borehole radar and acoustic systems have been developed and used in models and at an opencast site. They have been operated in both transmission and reflection modes, although attenuation in surface coal was found to be severe in much of the seam and it was not expected that any clear target identification would be obtained. Equipment to enable underground radar and acoustic measurements is now substantially complete and the first transmission trials in deep coal are expected during 1989. Where material properties and noise levels prove promising, trials will be extended to reflection studies and subsequently to the incorporation and optimisation of transducers within the steel drill string. These trails will be accompanied by the development and implementation of any necessary signal processing. 95 refs., 97 figs., 2 tabs.

    1999-12-01

    This study determined which types of laparoscopic instruments are most often used in Europe, why they are being used, and what problems exist while using the instruments. The handles were also evaluated according to ergonomic design criteria. A questionnaire was send to 62 experienced surgeons in 19 countries. The laparoscopic instruments were divided into four groups: instruments with similar functionality and handgrip model were grouped together. Eight questions were asked for every group about the type of instrument (disposable, reusable, or semireusable), the type of handle, the reason for using a specific instrument, and the experience of discomfort while using the instrument. The handles of the instruments of the group that were associated with the greatest discomfort were ergonomically evaluated on eight aspects (dimensions, angles, and control). Half of the questionnaires were returned. In every group, about 80% of the instruments the surgeons employed were reusable. The chief reason for using a specific type was the good cost-quality of the product and satisfying experiences with other products of the brand. The discomfort was pressure on thumb and fingers (scissors handle) and fixating the tip (ratchet). The handle of the instruments that causes the most discomfort met only three of the eight ergonomic requirements. Most of the laparoscopic instruments employed by surgeons in Europe are reusable. A significant number of the instruments cause discomfort. These instruments do not meet standard ergonomic requirements.

    Environmental reporting is increasingly important for medical facilities. Currently, hospitals can determine the content of an environmental report as they see fit. To examine the utility and scope of an employee survey as an instrument for the preparation of an environmental report at the University Hospital Greifswald. For this purpose a questionnaire was developed with a focus on environmental behaviour and the significance attached to the protection of the environment. The employees of the University Medicine Greifswald attach an unexpectedly high significance to the protection of the environment. Based on this finding, this potential should be used to promote the optimal implementation of ecological-economic behaviour within the University Medicine. An employee survey is a useful instrument in the preparation of an environmental report.

    Full Text Available The paper highlights the importance of managing service quality in banking that can positively affect customer satisfaction. The goal of the given study is to develop an instrument for measuring service quality perceived by Latvian banks’ retail customers and to determine the most important contributors to customer satisfaction. To achieve this purpose, randomly selected customers of Latvian banks were surveyed, using the authors’ developed questionnaire. The proposed instrument was tested for reliability and validity, using techniques of confirmatory factor analysis. Exploratory factor analysis yielded five service quality dimensions (factors that allowed constructing customer satisfaction factor model EPICA: E – expenses, P – product, I – image, C – competence and emotional intellect, A – access. The subsequent correlation analysis revealed that the strongest relationship is between customer satisfaction and C factor. The results of the current research are crucially important for Latvian banks’ executives because the majority of previous studies in the related field offered measurement scales adequate for measuring service quality in other industries. Besides, the proposed questionnaire is exclusively developed for Latvia and considers Latvian banking sector specifics.

    The purpose of this study is to develop a valid and reliable instrument to measure nursing students' (NSs') perceptions of civil and uncivil behaviors displayed by direct care nurses in the hospital clinical environment. Incivility in nursing has been well documented. However, little is known about perceptions of incivility by NSs in the hospital clinical environment and its effects on NSs' transition to professional practice. A 13-item instrument was developed using literature, faculty feedback, and a semistructured focus group. The instrument was administered to convenience samples of NSs at a Midwest, Magnet-designated pediatric hospital (N = 496). Findings indicated high reliability and validity of the instrument, with a Cronbach's α of .930. This study has produced a valid and reliable survey instrument to measure the perception of civil and noncivil behaviors on the part of clinical nurses as rated by NSs in hospital clinical settings. The use of this instrument will be beneficial to nurse executives in measuring these perceptions in their clinical settings.

    The Galactic All-Sky Survey is a survey of Galactic atomic hydrogen emission in the southern sky observed with the Parkes 64-m Radio Telescope. The first data release (GASS I) concerned survey goals and observing techniques, the second release (GASS II) focused on stray radiation and instrumental corrections. We seek to remove the remaining instrumental effects and present a third data release. We use the HEALPix tessellation concept to grid the data on the sphere. Individual telescope records are compared with averages on the nearest grid position for significant deviations. All averages are also decomposed into Gaussian components with the aim of segregating unacceptable solutions. Improved priors are used for an iterative baseline fitting and cleaning. In the last step we generate 3-D FITS data cubes and examine them for remaining problems. We have removed weak, but systematic baseline offsets with an improved baseline fitting algorithm. We have unraveled correlator failures that cause time dependent oscil...

    The Trauma Center Organizational Culture Survey (TRACCS) instrument was developed to assess organizational culture of trauma centers enrolled in the American College of Surgeons Trauma Quality Program (ACS TQIP). The objective is to provide evidence on the psychometric properties of the factors of TRACCS and describe the current organizational culture of TQIP-enrolled trauma centers. A cross-sectional study was conducted by surveying a sampling of employees at 174 TQIP-enrolled trauma centers. Data collection was preceded by multistep survey development. Psychometric properties were assessed by an exploratory factor analysis (construct validity) and the item-total correlations and Cronbach alpha were calculated (internal reliability). Statistical outcomes of the survey responses were measured by descriptive statistics and mixed effect models. The response rate for trauma center participation in the study was 78.7% (n = 137). The factor analysis resulted in 16 items clustered into three factors as described: opportunity, pride, and diversity, trauma center leadership, and employee respect and recognition. TRACCS was found to be highly reliable with a Cronbach alpha of 0.90 in addition to the three factors (0.91, 0.90, and 0.85). Considerable variability of TRACCS overall and factor score among hospitals was measured, with the largest interhospital deviations among trauma center leadership. More than 80% of the variability in the responses occurred within rather than between hospitals. TRACCS was developed as a reliable tool for measuring trauma center organizational culture. Relationships between TQIP outcomes and measured organizational culture are under investigation. Trauma centers could apply TRACCS to better understand current organizational culture and how change tools can impact culture and subsequent patient and process outcomes.

    We explored the psychometric properties of 15 survey questions that assessed abortion providers' perceptions of stigma and its impact on providers' professional and personal lives referred to as the Abortion Provider Stigma Survey (APSS). We administered the survey to a sample of abortion providers recruited for the Providers' Share Workshop (N = 55). We then completed analyses using Stata SE/12.0. Exploratory factor analysis, which resulted in 13 retained items and identified three subscales: disclosure management, resistance and resilience, and discrimination. Stigma was salient in abortion provider's lives: they identified difficulties surrounding disclosure (66%) and felt unappreciated by society (89%). Simultaneously, workers felt they made a positive contribution to society (92%) and took pride in their work (98%). Paired t-test analyses of the pre- and post-Workshop APSS scores showed no changes in the total score. However, the Disclosure Management subscale scores were significantly lower (indicating decreased stigma) for two subgroups of participants: those over the age of 30 and those with children. This analysis is a promising first step in the development of a quantitative tool for capturing abortion providers' experiences of and responses to pervasive abortion stigma.

    Few instruments provide reliable and valid data on child well-being and contextual assets during middle childhood, using children as informants. The authors developed a population-level, self-report measure of school-aged children's well-being and assets-the Middle Years Development Instrument (MDI)-and examined its reliability and validity. The MDI was designed to assess child well-being inside and outside of school on five dimensions: (1) Social and emotional development, (2) Connectedness to peers and to adults at school, at home, and in the neighborhood, (3) School experiences, (4) Physical health and well-being, and (5) Constructive use of time after school. This paper describes the theoretical framework, selection of items and scales for the survey, and four studies that were conducted to revise the MDI and examine its psychometric properties. The findings indicate a theoretically predicted factor structure, high internal consistency, and document the convergent and discriminant validity of the MDI scales. The discussion delineates a plan for future validation studies that address further validity questions, such as predictive validity, measurement invariance, and fairness/bias, and provides a brief outlook of how the MDI may be used by practitioners, educators, and decision makers in schools and communities to motivate and inform action in support children's well-being.

    The Centre de Recherche Astrophysique de Lyon (CRAL) has recently developed two instrument simulators for spectrographic instruments. They are based on Fourier optics, and model the whole chain of acquisition, taking into account both optical aberrations and diffraction effects, by propagating a wavefront through the instrument, according to the Fourier optics concept. One simulates the NIRSpec instrument, a near-infrared multi-object spectrograph for the future James Webb Space Telescope (JWST). The other one models the Multi Unit Spectroscopic Explorer (MUSE) instrument, a second-generation integral-field spectrograph for the Very Large Telescope (VLT). The two simulators have been developed in different contexts (subcontracted versus developed internally), and for very different instruments (space-based versus ground-based), which strengthen the CRAL experience. This paper describes the lessons learned while developing these simulators: development methods, phasing with the project, points to focus on, getting data, interacting with scientists and users, etc.

  2. Development of a Compact, Deep-Penetrating Heat Flow Instrument for Lunar Landers: In-Situ Thermal Conductivity System

    2012-01-01

    Geothermal heat flow is obtained as a product of the geothermal gradient and the thermal conductivity of the vertical soil/rock/regolith interval penetrated by the instrument. Heat flow measurements are a high priority for the geophysical network missions to the Moon recommended by the latest Decadal Survey and previously the International Lunar Network. One of the difficulties associated with lunar heat flow measurement on a robotic mission is that it requires excavation of a relatively deep (approx 3 m) hole in order to avoid the long-term temporal changes in lunar surface thermal environment affecting the subsurface temperature measurements. Such changes may be due to the 18.6-year-cylcle lunar precession, or may be initiated by presence of the lander itself. Therefore, a key science requirement for heat flow instruments for future lunar missions is to penetrate 3 m into the regolith and to measure both thermal gradient and thermal conductivity. Engineering requirements are that the instrument itself has minimal impact on the subsurface thermal regime and that it must be a low-mass and low-power system like any other science instrumentation on planetary landers. It would be very difficult to meet the engineering requirements, if the instrument utilizes a long (> 3 m) probe driven into the ground by a rotary or percussive drill. Here we report progress in our efforts to develop a new, compact lunar heat flow instrumentation that meets all of these science and engineering requirements.

    Cultural competence of healthcare professionals (HCPs) is recognized as a strategy to reduce cultural disparities in healthcare. However, standardised, valid and reliable instruments to assess HCPs' cultural competence are notably lacking. The present study aims to 1) identify the core components of cultural competence from a healthcare perspective, 2) to develop a self-report instrument to assess cultural competence of HCPs and 3) to evaluate the psychometric properties of the new instrument. The conceptual model and initial item pool, which were applied to the cross-cultural competence instrument for the healthcare profession (CCCHP), were derived from an expert survey (n = 23), interviews with HCPs (n = 12), and a broad narrative review on assessment instruments and conceptual models of cultural competence. The item pool was reduced systematically, which resulted in a 59-item instrument. A sample of 336 psychologists, in advanced psychotherapeutic training, and 409 medical students participated, in order to evaluate the construct validity and reliability of the CCCHP. Construct validity was supported by principal component analysis, which led to a 32-item six-component solution with 50% of the total variance explained. The different dimensions of HCPs' cultural competence are: Cross-Cultural Motivation/Curiosity, Cross-Cultural Attitudes, Cross-Cultural Skills, Cross-Cultural Knowledge/Awareness and Cross-Cultural Emotions/Empathy. For the total instrument, the internal consistency reliability was .87 and the dimension's Cronbach's α ranged from .54 to .84. The discriminating power of the CCCHP was indicated by statistically significant mean differences in CCCHP subscale scores between predefined groups. The 32-item CCCHP exhibits acceptable psychometric properties, particularly content and construct validity to examine HCPs' cultural competence. The CCCHP with its five dimensions offers a comprehensive assessment of HCPs' cultural competence, and has the

    Perceptions of mentors' practices related to primary science teaching from nine Australian universities (N = 331 final-year preservice teachers) were gathered through a literature-based instrument. Five factors that characterize effective mentoring practices in primary science teaching were supported by confirmatory factory analysis. These factors, namely, personal attributes, system requirements, pedagogical knowledge, modeling, and feedback, had Cronbach alpha coefficients of internal consistency reliability of .93, .76, .94, .95, and .92, respectively. Final model fit indexes were 2 = 1335, df = 513, CMIDF = 2.60, IFI = .922, CFI = .921, RMR = .066, RMSEA = .070 (p<.001). Specific mentoring interventions for improving primary science teaching practices may be implemented by measuring preservice teachers' perceptions of their mentoring with a valid and reliable instrument.

    This report gives a survey and a description of present and future policy instruments that have been or will become important for the development of the waste management system. Policy instruments here refers to laws, directives, taxes/fees, national/local goals and other regulating measures that the society introduce to steer the development of the waste management system. This work can thus be used as a dictionary or a guideline for these measures. The investigation has two goals: 1. To give representatives of the Swedish waste management system a summary of important policy instruments for the future development of the waste management system. 2. To give Waste Refinery a summary of these policy instruments that can be used for the discussions of how the research within the centre should develop during stage 2. A large number of policy instruments have been found during the study. These instruments have been, most likely will become, or may become important for the development of the waste management system. Most of them are described in this report. The selection made is presented in Table 1. Focus for the selection has been policy instruments that are important for the research activities within Waste Refinery, meaning policy instruments that direct or indirect can change the use of thermal and/or biological treatment as well as techniques and methods supporting these treatment methods.

    Two high-resolution neutron diffractometers dedicated to strain /stress investigations in polycrystalline materials are routinely operated at the medium-power reactor LVR-15 in Rez and are also opened for external users. Good luminosity of the diffractometers and a sufficiently high-resolution (FWHM of the instrumental Delta d/d - profile can be less than 2*10/sup -3/ at d/sub hkl/=0.2 nm) permit investigations of both the macro- and microstrains in the sample gauge volumes of several cubic millimetres. Excellent properties and abilities of the neutron diffraction strain scanners are documented by some results of experimental measurements. (11 refs).

    Following the Fukushima Dai-ichi Nuclear Power Plant accident in March 2011, extensive radiation monitoring and environmental clean-up activities have been conducted throughout the Fukushima region. Outside air temperatures there reach 40 °C in summer and -20 °C in winter, which are beyond the quoted operational range of many radiation survey instruments. Herein, temperature performance of four types of portable Japanese radiation survey instruments widely used in Fukushima was experimentally investigated using a temperature-controlled chamber. They included two ionization chamber type instruments, Fuji NHA1 and Aloka ICS-323C, and two NaI(Tl) scintillation type ones, Fuji NHC7 and Aloka TCS-172B. Experimental results showed significantly diverse characteristics on the temperature dependences from one type of instrument to another. For example, NHA1 overestimated the ambient dose-equivalent rate by as much as 17% at -30 °C and 10% at 40 °C, whereas the TCS-172B readings underestimated the rate by 30% at -30 °C and 7% at 40 °C.

  13. Surveys: an introduction.

    Surveys are a valuable research tool for studying the knowledge, attitudes, and behavior of a study population. This article explores quantitative analyses of written questionnaires as instruments for survey research. Obtaining accurate and precise information from a survey requires minimizing the possibility of bias from inappropriate sampling or a flawed survey instrument, and this article describes strategies to minimize sampling bias by increasing response rates, comparing responders to nonresponders, and identifying the appropriate sampling population. It is crucial that the survey instrument be valid, meaning that it actually measures what the investigator intends it to measure. In developing a valid survey instrument, it can be useful to adapt survey instruments that were developed by other researchers and to conduct extensive pilot-testing of your survey instrument.

    2002-01-01

    This study reports on the development of a valid and reliable survey instrument to be used by college biology teachers at Christian colleges to evaluate the scientific attitudes and the attitudes about evolution and attitudes about creationism of their students. Survey questions were largely derived from student responses to open ended interview questions. Content validity was strong as indicated by agreement among content experts through the use of a content validity rating form. Construct validity was examined through the use of principal components analysis of 165 survey responses. Four factors were identified as a result of this analysis: "evolution support," "views of how scientists think/operate," "scientific attitudes," and "hypotheses and theories." These factors were found to be consistent with the three theoretical constructs of scientific attitudes, attitudes about evolution, and attitudes about creationism. Overall instrument reliability, Cronbach's reliability coefficient, alpha, was determined to be 0.64 (N = 165). Readability was found to be at the 7 th grade level. The instrument should be comprehensible by college students.

  15. Development of a Survey to Assess the Acceptability of an Innovative Contraception Practice among Rural Pharmacists

    2014-03-01

    Full Text Available Improved access to effective contraceptive methods is needed in Canada, particularly in rural areas, where unintended pregnancy rates are high and specific sexual health services may be further away. A rural pharmacist may be the most accessible health care professional. Pharmacy practice increasingly incorporates cognitive services. In Canada many provinces allow pharmacists to independently prescribe for some indications, but not for hormonal contraception. To assess the acceptability for the implementation of this innovative practice in Canada, we developed and piloted a survey instrument. We chose questions to address the components for adoption and change described in Rogers’ “diffusion of innovations” theory. The proposed instrument was iteratively reviewed by 12 experts, then focus group tested among eight pharmacists or students to improve the instrument for face validity, readability, consistency and relevancy to community pharmacists in the Canadian context. We then pilot tested the survey among urban and rural pharmacies. 4% of urban and 35% of rural pharmacies returned pilot surveys. Internal consistency on repeated re-phrased questions was high (Cronbach’s Alpha = 0.901. We present our process for the development of a survey instrument to assess the acceptability and feasibility among Canadian community pharmacists for the innovative practice of the independent prescribing of hormonal contraception.

    2014-06-01

    Internationally, efforts to increase student interest in science, technology, engineering, and mathematics (STEM) careers have been on the rise. It is often the goal of such efforts that increased interest in STEM careers should stimulate economic growth and enhance innovation. Scientific and educational organizations recommend that efforts to interest students in STEM majors and careers begin at the middle school level, a time when students are developing their own interests and recognizing their academic strengths. These factors have led scholars to call for instruments that effectively measure interest in STEM classes and careers, particularly for middle school students. In response, we leveraged the social cognitive career theory to develop a survey with subscales in science, technology, engineering, and mathematics. In this manuscript, we detail the six stages of development of the STEM Career Interest Survey. To investigate the instrument's reliability and psychometric properties, we administered this 44-item survey to over 1,000 middle school students (grades 6-8) who primarily were in rural, high-poverty districts in the southeastern USA. Confirmatory factor analyses indicate that the STEM-CIS is a strong, single factor instrument and also has four strong, discipline-specific subscales, which allow for the science, technology, engineering, and mathematics subscales to be administered separately or in combination. This instrument should prove helpful in research, evaluation, and professional development to measure STEM career interest in secondary level students.

  3. Mechanisms Fostering Social Entrepreneurship as Potential Instruments for Economic Development: The Eastern Partnership Perspective

    Directory of Open Access Journals (Sweden)

    Plotnieks Dāvis

    2014-10-01

    Full Text Available With its plan to assign 600 million euros through the European Neighbourhood Instrument for Eastern Partnership countries, the European Union intended to increase the efficiency of institutions, attenuate social problems, and create an environment that fosters economic growth and human well-being in Armenia, Azerbaijan, Belarus, Georgia, Moldova, and Ukraine. A few scholars have criticized the amount of funding and planned initiatives of the European Neighbourhood Instrument as insufficient and suggested that in order to foster cooperation and support reforms in its Eastern Partnership countries, more action should be taken. In times when European Commission budget is under constraints of consolidation and increase of aid for supporting European Neighbourhood countries is hardly possible, alternative solutions for tempering social problems need to be assessed. Various scientists, philanthropists and entrepreneurs see social entrepreneurship as a tool for solving social problems in a sustainable way where business thinking is being combined with non-profit philosophy. Contrary to government support and intervention for solving social problems, social entrepreneurship is already being used as tool that initially addresses joint needs--solve social problems and create revenue that provides much needed income for sustainable business initiatives. This paper analyzes the concept of social entrepreneurship, examples where social entrepreneurship is solving social problems, and mechanisms that can foster these phenomena. The aim of this paper is to examine different mechanisms of how governments can foster the creation and development of social entrepreneurship. Unique survey data derived from a project examining social entrepreneurship in Europe is used. It is concluded that by adopting mechanisms proven in various developed countries, the Eastern Partnership countries can stimulate social entrepreneurship, thus attenuating social problems and

    Racial identity invalidation, others' denial of an individual's racial identity, is a salient racial stressor with harmful effects on the mental health and well-being of Multiracial individuals. The purpose of this study was to create a psychometrically sound measure to assess racial identity invalidation for use with Multiracial individuals (N = 497). The present sample was mostly female (75%) with a mean age of 26.52 years (SD = 9.60). The most common racial backgrounds represented were Asian/White (33.4%) and Black/White (23.7%). Participants completed several online measures via Qualtrics. Exploratory factor analyses revealed 3 racial identity invalidation factors: behavior invalidation, phenotype invalidation, and identity incongruent discrimination. A confirmatory factor analysis provided support for the initial factor structure. Alternative model testing indicated that the bifactor model was superior to the 3-factor model. Thus, a total score and/or 3 subscale scores can be used when administering this instrument. Support was found for the reliability and validity of the total scale and subscales. In line with the minority stress theory, challenges with racial identity mediated relationships between racial identity invalidation and mental health and well-being outcomes. The findings highlight the different dimensions of racial identity invalidation and indicate their negative associations with connectedness and psychological well-being.

  5. Development of bacterial colony phenotyping instrument using reflected scatter light

    Science.gov (United States)

    Doh, Iyll-Joon

    Bacterial rapid detection using optical scattering technology (BARDOT) involves in differentiating elastic scattering pattern of bacterial colony. This elastic light scatter technology has shown promising label-free classification rate. However, there is limited success in certain circumstances where either a growth media or a colony has higher opacity. This situation is due to the physical principles of the current BARDOT which mainly relies on optical patterns generated by transmitted signals. Incoming light is obstructed and cannot be transmitted through the dense bacterial colonies, such as Lactobacillus, Yeast, mold and soil bacteria. Moreover, a blood agar, widely used in clinical field, is an example of an opaque media that does not allow light to be transmitted through. Therefore, in this research, a newly designed reflection type scatterometer is presented. The reflection type scatterometer measures the elastic scattering pattern generated by reflected signal. A theoretical model to study the optical pattern characteristic with respect to bacterial colony morphology is presented. Both theoretical and experiment results show good agreement that the size of backward scattering pattern has positive correlation to colony aspect ratio, a colony elevation to diameter ratio. Four pathogenic bacteria on blood agar, Escherichia coli K12, Listeria innocua, Salmonella Typhimurium, and Staphylococcus aureus, are tested and measured with proposed instrument. The measured patterns are analyzed with a classification software, and high classification rate can be achieved.

    A practical, reliable, and valid instrument is needed to measure the impact of the learning environment on medical students' well-being and educational experience and to meet medical school accreditation requirements. From 2012 to 2015, medical students were surveyed at the end of their first, second, and third year of studies at four medical schools. The survey assessed students' perceptions of the following nine dimensions of the school culture: vitality, self-efficacy, institutional support, relationships/inclusion, values alignment, ethical/moral distress, work-life integration, gender equity, and ethnic minority equity. The internal reliability of each of the nine dimensions was measured. Construct validity was evaluated by assessing relationships predicted by our conceptual model and prior research. Assessment was made of whether the measurements were sensitive to differences over time and across institutions. Six hundred and eighty-six students completed the survey (49 % women; 9 % underrepresented minorities), with a response rate of 89 % (range over the student cohorts 72-100 %). Internal consistency of each dimension was high (Cronbach's α 0.71-0.86). The instrument was able to detect significant differences in the learning environment across institutions and over time. Construct validity was supported by demonstrating several relationships predicted by our conceptual model. The C-Change Medical Student Survey is a practical, reliable, and valid instrument for assessing the learning environment of medical students. Because it is sensitive to changes over time and differences across institution, results could potentially be used to facilitate and monitor improvements in the learning environment of medical students.

    To develop an instrument for assessing physician attitudes toward quality incentive programs, and to assess its reliability and validity. Study involved primary data collection. A 40-item paper and pencil survey of primary care physicians in Rochester, New York, and Massachusetts was conducted between May 2004 and December 2004. Seven-hundred and ninety-eight completed questionnaires were received, representing a response rate of 32 percent (798/2,497). Based on an extensive review of the literature and discussions with experts in the field, we developed a conceptual framework representing the features of pay-for-performance (P4P) programs hypothesized to affect physician behavior in that context. A draft questionnaire was developed based on that conceptual model and pilot tested in three groups of physicians. The questionnaire was modified based on the physician feedback, and the revised version was distributed to 2,497 primary care physicians affiliated with two of the seven sites participating in Rewarding Results, a national evaluation of quality target and financial incentive programs. Respondents were randomly divided into a derivation and a validation sample. Exploratory factor analysis was applied to the responses of the derivation sample. Those results were used to create scales in the validation sample, and these were then subjected to multitrait analysis (MTA). One scale representing physicians' perception of the impact of P4P on their clinical practice was regressed on the other scales as a test of construct validity. Seven constructs were identified and demonstrated substantial convergent and discriminant validity in the MTA: awareness and understanding, clinical relevance, cooperation, unintended consequences, control, financial salience, and impact. Internal consistency reliabilities (Cronbach's alpha coefficients) ranged from 0.50 to 0.80. A statistically significant 25 percent of the variation in perceived impact was accounted for by physician

  8. Development of an instrument to measure student attitudes toward science fairs

    Science.gov (United States)

    Huddleston, Claudia A.

    Science fairs are woven into the very fabric of science instruction in the United States and in other countries. Even though thousands of students participate in science fairs every year, no instrument to measure student attitudes toward partaking in this hands-on learning experience has been fully developed and available for school administrators and teachers to assess the perceived value that current students attribute to participation in science fairs. Therefore, the purpose of this study was to continue the development and refinement of an instrument that measured student attitudes towards science fairs based on an unpublished instrument created by Michael (2005). The instrument developed and tested using 110 students at two different middle schools in southwest Virginia. The instrument consisted of 45 questions. After applying a principal component factor analysis, the instrument was reduced to two domains, enjoyment and value. The internal consistency of the instrument was calculated using Cronbach's alpha and showed good internal consistency of .89 between the two domains. Further analysis was conducted using a Pearson product-moment test and showed a significant positive correlation between enjoyment and value (r = .78). Demographic information was explored concerning the domains using a series of statistical tests, and results revealed no significant differences among race and science fair category. However, a significant difference was found among gender and students who won awards and those who did not. The conclusion was that further development and refinement of the instrument should be conducted.

    Preventive home visits with multidimensional geriatric assessment have been shown to delay or prevent the onset of disability and reduce nursing home admissions in older people. The purpose of the present study was to develop and test a multidimensional instrument for in-home preventive assessments in older persons. In developing the instrument, we conducted a systematic literature review of risk factors for functional status decline and of appropriate instruments for measuring these risk factors. Based on an Expert Panel using a modified Delphi process [1] the risk factor domains for functional status decline were chosen, [2] the instruments for evaluating each of the included risk factor domains were selected, and [3] the individual instruments were combined into one comprehensive assessment instrument. A German language version of the original English version of the instrument was developed based on translation, backtranslation, and cultural adaptation. The feasibility of use of the new instrument was evaluated in a field test in 150 people aged 75 years and older in Hamburg, Ulm, Germany, and Bern, Switzerland. The instrument was well accepted by the older persons. The prevalence of risk factors for functional status decline in these populations (e.g., physical inactivity, urinary incontinence, vision impairment) was high. There was also a high prevalence of underuse of preventive care measures (e.g., no pneumococcal vaccination in over 95 percent of persons). These preliminary results support the possible usefulness of this instrument for conducting preventive home visits or for epidemiological purposes (e.g., prevention surveillance). In a next phase, the test-retest reliability of the instrument, and the feasibility and reliability of self-administration as compared to interviewer administration will be described in a separate paper.

    Through the SNL New Mexico Small Business Assistance (NMSBA) program, several Sandia engineers worked with the Environmental Restoration Group (ERG) Inc. to verify and validate a novel algorithm used to determine the scanning Critical Level (L c ) and Minimum Detectable Concentration (MDC) (or Minimum Detectable Areal Activity) for the 102F scanning system. Through the use of Monte Carlo statistical simulations the algorithm mathematically demonstrates accuracy in determining the L c and MDC when a nearest-neighbor averaging (NNA) technique was used. To empirically validate this approach, SNL prepared several spiked sources and ran a test with the ERG 102F instrument on a bare concrete floor known to have no radiological contamination other than background naturally occurring radioactive material (NORM). The tests conclude that the NNA technique increases the sensitivity (decreases the L c and MDC) for high-density data maps that are obtained by scanning radiological survey instruments.

    The General, Organic, and Biological Chemistry Knowledge Assessment (GOB-CKA) is a multiple-choice instrument designed to assess students' understanding of the chemistry topics deemed important to clinical nursing practice. This manuscript describes the development process of the individual items along with a psychometric evaluation of the final version of the items and instrument. In developing items for the GOB-CKA, essential topics were identified through a series of expert interviews (with practicing nurses, nurse educators, and GOB chemistry instructors) and confirmed through a national survey. Individual items were tested in qualitative studies with students from the target population for clarity and wording. Data from pilot and beta studies were used to evaluate each item and narrow the total item count to 45. A psychometric analysis performed on data from the 45-item final version was used to provide evidence of validity and reliability. The final version of the instrument has a Cronbach's alpha value of 0.76. Feedback from an expert panel provided evidence of face and content validity. Convergent validity was estimated by comparing the results from the GOB-CKA with the General-Organic-Biochemistry Exam (Form 2007) of the American Chemical Society. Instructors who wish to use the GOB-CKA for teaching and research may contact the corresponding author for a copy of the instrument.

    Full Text Available OBJECTIVE: To develop an instrument to assess discrimination effects on health outcomes and behaviors, capable of distinguishing harmful differential treatment effects from their interpretation as discriminatory events. METHODS: Successive versions of an instrument were developed based on a systematic review of instruments assessing racial discrimination, focus groups and review by a panel comprising seven experts. The instrument was refined using cognitive interviews and pilot-testing. The final version of the instrument was administered to 424 undergraduate college students in the city of Rio de Janeiro, Southeastern Brazil, in 2010. Structural dimensionality, two types of reliability and construct validity were analyzed. RESULTS: Exploratory factor analysis corroborated the hypothesis of the instrument's unidimensionality, and seven experts verified its face and content validity. The internal consistency was 0.8, and test-retest reliability was higher than 0.5 for 14 out of 18 items. The overall score was higher among socially disadvantaged individuals and correlated with adverse health behaviors/conditions, particularly when differential treatments were attributed to discrimination. CONCLUSIONS: These findings indicate the validity and reliability of the instrument developed. The proposed instrument enables the investigation of novel aspects of the relationship between discrimination and health.

    This study aimed to develop an evaluation instrument constructed by CIPP model on the implementation of portfolio assessment in science learning. This study used research and development (R & D) method; adapting 4-D by the development of non-test instrument, and the evaluation instrument constructed by CIPP model. CIPP is the abbreviation of Context, Input, Process, and Product. The techniques of data collection were interviews, questionnaires, and observations. Data collection instruments were: 1) the interview guidelines for the analysis of the problems and the needs, 2) questionnaire to see level of accomplishment of portfolio assessment instrument, and 3) observation sheets for teacher and student to dig up responses to the portfolio assessment instrument. The data obtained was quantitative data obtained from several validators. The validators consist of two lecturers as the evaluation experts, two practitioners (science teachers), and three colleagues. This paper shows the results of content validity obtained from the validators and the analysis result of the data obtained by using Aikens' V formula. The results of this study shows that the evaluation instrument based on CIPP models is proper to evaluate the implementation of portfolio assessment instruments. Based on the experts' judgments, practitioners, and colleagues, the Aikens' V coefficient was between 0.86-1,00 which means that it is valid and can be used in the limited trial and operational field trial.

    The Jet Propulsion Laboratory's Advanced Design Team was formed in April 1995 to improve the quality and reduce the cost of JPL proposals and advanced mission studies. Currently a consolidation attempt is underway to develop a Model Library for use by JPL's Advanced Projects Design Team by collecting existing instrument models for inclusion in the library. This will allow users to readily find models of interest. In addition to this, there is also an attempt underway to develop a new approach to instrument model design used by the Advanced Design Team (Team X). This new approach consists of splitting up the different model parts such as orbital parameters, instrument parameters and instrument outputs into separate searchable parts. The user can then decide between design trades and use the different pieces to construct a model that will fit their needs. As well, this will lead to the opportunity for the large variety of usable instrument models.

    Full Text Available As one of the oldest instruments known to mankind, the flute is present in some form in nearly every culture and ethnic group in the world. However, in Western music in particular, the flute has taken its place as an important part of musical culture, both as a solo and an ensemble instrument. The flute has also undergone its most significant technological developments in Western musical culture, moving from the bone keyless flutes of the Prehistoric era to the gold and silver instruments known to performers today. During the Renaissance and Baroque periods in particular, however, the flute rose to popularity as a solo instrument and began to evolve into its modern form. New developments in the design and mechanics of the instrument drove this increased interest, which ultimately gave the flute a prominent position in music that has lasted throughout history.

    The purpose of this study was to compare the effects of root canal preparation techniques and instrumentation length on the development of apical root cracks. Forty extracted mandibular premolars with straight roots were randomly selected and mounted on resin blocks with simulated periodontal ligaments, and the apex was exposed. The teeth were divided into four groups of 10 teeth each for different canal preparation techniques and instrumentation lengths: group A: step-back preparation (SB) with stainless steel files (SF) using root canal length (RCL) to guide instrumentation length; group B: SB using RCL - 1 mm; group C: crown-down preparation (CD) with Profile using RCL; and group D: CD with PF using RCL - 1 mm. Digital images of the instrumentation sequence were compared for each tooth. Statistical analysis revealed a significant effect of instrumentation length (p 0.05) on the development of apical cracks.

    Full Text Available Abstract Background Instruments to measure mental health and well-being are largely developed and often used within Western populations and this compromises their validity in other cultures. A previous qualitative study in Singapore demonstrated the relevance of spiritual and religious practices to mental health, a dimension currently not included in exiting multi-dimensional measures. The objective of this study was to develop a self-administered measure that covers all key and culturally appropriate domains of mental health, which can be applied to compare levels of mental health across different age, gender and ethnic groups. We present the item reduction and validation of the Positive Mental Health (PMH instrument in a community-based adult sample in Singapore. Methods Surveys were conducted among adult (21-65 years residents belonging to Chinese, Malay and Indian ethnicities. Exploratory and confirmatory factor analysis (EFA, CFA were conducted and items were reduced using item response theory tests (IRT. The final version of the PMH instrument was tested for internal consistency and criterion validity. Items were tested for differential item functioning (DIF to check if items functioned in the same way across all subgroups. Results: EFA and CFA identified six first-order factor structure (General coping, Personal growth and autonomy, Spirituality, Interpersonal skills, Emotional support, and Global affect under one higher-order dimension of Positive Mental Health (RMSEA = 0.05, CFI = 0.96, TLI = 0.96. A 47-item self-administered multi-dimensional instrument with a six-point Likert response scale was constructed. The slope estimates and strength of the relation to the theta for all items in each six PMH subscales were high (range:1.39 to 5.69, suggesting good discrimination properties. The threshold estimates for the instrument ranged from -3.45 to 1.61 indicating that the instrument covers entire spectrums for the six dimensions. The

    Context. The Galactic All-Sky Survey (GASS) is a survey of Galactic atomic hydrogen (H i) emission in the southern sky observed with the Parkes 64-m Radio Telescope. The first data release (GASS I) concerned survey goals and observing techniques, the second release (GASS II) focused on stray radiation and instrumental corrections. Aims: We seek to remove the remaining instrumental effects and present a third data release. Methods: We use the HEALPix tessellation concept to grid the data on the sphere. Individual telescope records are compared with averages on the nearest grid position for significant deviations. All averages are also decomposed into Gaussian components with the aim of segregating unacceptable solutions. Improved priors are used for an iterative baseline fitting and cleaning. In the last step we generate 3D FITS data cubes and examine them for remaining problems. Results: We have removed weak, but systematic baseline offsets with an improved baseline fitting algorithm. We have unraveled correlator failures that cause time dependent oscillations; errors cause stripes in the scanning direction. The remaining problems from radio frequency interference (RFI) are spotted. Classifying the severeness of instrumental errors for each individual telescope record (dump) allows us to exclude bad data from averages. We derive parameters that allow us to discard dumps without compromising the noise of the resulting data products too much. All steps are reiterated several times: in each case, we check the Gaussian parameters for remaining problems and inspect 3D FITS data cubes visually. We find that in total ~1.5% of the telescope dumps need to be discarded in addition to ~0.5% of the spectral channels that were excluded in GASS II. Conclusions: The new data release (GASS III) facilitates data products with improved quality. A new web interface, compatible with the previous version, is available for download of GASS III FITS cubes and spectra.

    2015-09-01

    Macromolecular imaging and tomography of ice embedded samples has developed into a mature imaging technology, in structural biology today widely referred to simply as cryo electron microscopy.(1) While the pioneers of the technique struggled with ill-suited instruments, state-of-the-art cryo microscopes are now readily available and an increasing number of groups are producing excellent high-resolution structural data of macromolecular complexes, of cellular organelles, or the morphology of whole cells. Instrumentation developers, however, are offering yet more novel electron optical devices, such as energy filters and monochromators, aberration correctors or physical phase plates. Here we discuss how current instrumentation has already changed cryo EM, and how newly available instrumentation - often developed in other fields of electron microscopy - may further develop the use and applicability of cryo EM to the imaging of single isolated macromolecules of smaller size or molecules embedded in a crowded cellular environment.

    2012-01-01

    Positron emission tomography (PET) plays important roles in cancer diagnosis and molecular imaging research; but potential points remain for which big improvements could be made, including resolution, sensitivity and costs. For example, the sensitivity of present PET scanners does not exceed 10%. This means that more than 90% of the gamma-rays emitted from a subject are not utilized for imaging. Therefore, research on next generation PET technologies remains a hot topic worldwide. In this paper, we introduce some research trends by describing PET physics research in the National Institute of Radiological Sciences (NIRS). A depth-of-interaction (DOI) detector, for which various methods have been studied, will be a key device to get any significant improvement in sensitivity while maintaining high spatial resolution. DOI measurement also has a potential to expand PET application fields because it allows for more flexible detector arrangement. As an example, we are developing the world's first, open-type PET geometry "OpenPET", which is expected to lead to PET imaging during treatment. The DOI detector itself continues to evolve with the help of recently developed semiconductor photodetectors, often referred to as silicon photomultipliers (SiPMs). We are developing a SiPM-based DOI detector to achieve sub-mm spatial resolution, which is reaching the theoretical limitation of PET imaging.

    Manjola Duli

    2016-07-01

    Full Text Available Regional development is a cross-cutting issue. The current approach to regional development in Europe is place-based, in which multidimensional analyses are carried out and strategies and policies developed in relation to territorially defined socio-economic and environmental factors. In our study we have largely followed this approach, looking at long-term changes in a wide set of development indicators across Albania. As a result several regional typologies are presented as well as broad recommendations for regional development policy formulation. Albania has two levels of governance: national, county (qarks and local (municipalities. Directly elected bodies exist at central and local levels. Qark councils consist of delegated representatives from local units. Albania’s territory is organized into 12 counties and 61 local government units. There are neither administrative nor self-governing regions in Albania corresponding to NUTS 21 level classification. Qarks are the equivalent of NUTS 3 level. Currently in Albania there is no clear definition of a development region. In general it is perceived that qarks can be considered an appropriate level at which regional development is analyzed, promoted and monitored. Although we have followed this concept, both due to data available and no better practical alternative, there are clearly other possibilities which could surface in the medium-term perspective, for example: NUTS 2 delineation for Albania could lead to a situation when development issues will become also relevant at the macro level – practically the number of NUTS 2 regions in Albania could vary between 2 and 3 unless the country is allowed to stay one region; Territorial and administrative reforms could lead to a much smaller number of LGUs both at the basic municipality level and the qark level, especially that from a general RD perspective some of the qarks represent very small units, both in terms of population and size of the

    Illness-related stigma remains a serious problem in the management of HIV disease in Africa. This article describes a series of study phases conducted to develop and validate an instrument to measure HIV/AIDS-related stigma as perpetrated and experienced by nurses. Data were collected in Lesotho, Malawi, South Africa, Swaziland and Tanzania, from 2004-2006. The first phase was a qualitative study with focus group participants (n=251) to gather emic and etic descriptions of HIV/AIDS-related stigma in the five countries. Based on the qualitative data, a 46-item instrument was developed and tested during a second phase in the same five countries (n=244). The result of this phase was a 33-item, three-factor instrument with an average Cronbach alpha of 0.85. A third phase tested the instrument in 1474 nurses. The result was a final 19-item instrument, the HIV/AIDS Stigma Instrument - Nurse (HASI-N), comprised of two factors (Nurses Stigmatizing Patients and Nurses Being Stigmatized) with a Cronbach alpha of 0.90. Concurrent validity was tested by comparing the level of stigma with job satisfaction and quality of life. A significant negative correlation was found between stigma and job satisfaction. The HASI-N is the first inductively derived instrument measuring stigma experienced and enacted by nurses. It has the potential to be used not only to measure stigma, but also to develop stigma-reduction interventions.

    For correct information of coal resources in Japan and enhancement of coal resource exploration techniques, unexamined but promising coal resource districts in Japan were systematically examined by coal exploration utilizing new analytical technique and drilling. This exploration project started in 1982. Six offshore geophysical surveys, and forty four appraisal drilling were practiced for determining coal deposits in each district. In 1986, the successive survey and appraisal drilling were made in six districts. The re-analyses for the offshore geologic survey in Ariake sea district utilized new techniques such as partial migration of polymer, model analysis, etc., revealing the effectiveness for coal deposit structure. For Asagaya and Saruwatari district, VSP exploration utilizing appraisal drilling was conducted, giving reflection recordings corresponding to the geologic informations, which were useful for the precise data evaluation.

    Students' conceptions of work and energy are important to support the learning process in the classroom. For that reason, a diagnostic test instrument is needed to diagnose students' conception of work and energy. As a result, the researcher decided to develop Energy and Momentum Conceptual Survey (EMCS) instrument test into four-tier test diagnostic items. The purpose of this research is organized as the first step of four-tier test-formatted EMCS development as one of diagnostic test instruments on work and Energy. The research method used the 4D model (Defining, Designing, Developing and Disseminating). The instrument developed has been tested to 39 students in one of Senior High Schools. The resulting research showed that four-tier test-formatted EMCS is able to diagnose students' conception level of work and energy concept. It can be concluded that the development of four-tier test-formatted EMCS is one of potential diagnostic test instruments that able to obtain the category of students who understand concepts, misconceptions and do not understand about Work and Energy concept at all.

    Undergraduate educational settings often struggle to provide students with authentic biologically or medically relevant situations and problems that simultaneously improve their understanding of physics. Through exercises and laboratory activities developed in an elective Physics in Biomedicine course for upper-level biology or pre-health majors at Portland State University, we aim to teach fundamental physical concepts, such as light absorption and emission and atomic energy levels, through analysis of biological systems and medical devices. The activities address the properties of electromagnetic waves as they relate to the interaction with biological tissue and make links between physics and biomedical applications such as microscopy or laser eye surgery. We report on the effect that engaging students in tasks with actual medical equipment has had on their conceptual understanding of light and spectroscopy. These initial assessments indicate that students' understanding improves in some areas as a result of taking the course, but gains are not uniform and are relatively low for other topics. We also find a promising "nonshift" in student attitudes toward learning science as a result of taking the course. A long-term goal of this work is to develop these materials to the extent that they can eventually be imported into an introductory curriculum for life sciences majors.

    The impact of biotechnologies on peoples' everyday lives continuously increases. Measuring young peoples' attitudes toward biotechnologies is therefore very important and its results are useful not only for science curriculum developers and policy makers, but also for producers and distributors of genetically modified products. Despite of substantial number of instruments which focused on measuring student attitudes toward biotechnology, a majority of them were not rigorously validated. This study deals with the development and validation of an attitude questionnaire toward biotechnology. Detailed information on development and validation process of the instrument is provided. Data gathered from 326 university students provided evidence for the validity and reliability of the new instrument which consists of 28 attitude items on a five point likert type scale. It is believed that the instrument will serve as a valuable tool for both instructors and researchers in science education to assess students' biotechnology attitudes.

    Assessing the oxidative capacity of the atmosphere is important to address fundamental issues related to both air quality and climate change. However, recent measurements of total OH reactivity have highlighted an incomplete understanding of the hydroxyl radical (OH) budget, the main oxidizing agent in the atmosphere. This context has led to the development of several techniques for measuring total OH reactivity to better constrain atmospheric chemistry. This presentation will review the development of an OH reactivity instrument developed at Mines Douai, France. This instrument, based on the Comparative Reactivity Method (CRM), has been carefully characterized in the laboratory and has been compared to other OH reactivity instruments during two different field campaigns. These studies will be summarized to show that CRM instruments can perform reliable measurements in urban and remote areas providing that a few measurement artefacts are well characterized and accounted for during field campaigns.

  19. The Development of a Physics Self-Efficacy Instrument for Use in the Introductory Classroom

    Shaw, Kimberly A.

    2004-09-01

    Self-efficacy (SE) can be described as a person's belief in her/his own ability to accomplish a specific task to a given performance level, and is both content and context dependent. This may be especially important for female students in science, who tend to drop out of science classrooms with much better performance records than their male counterparts. The PACER group at SIUE has been developing an instrument to examine the relationship between physics SE and student performance in our introductory physics classrooms. Previously reported results suggesting no correlation between SE and performance in our physics classrooms led to the development of this new SE instrument. Development of the instrument, as well as field data from this pilot instrument emphasizing self-efficacy in physics (SEP) as it relates to gender, will be discussed.

    The characteristics and performance of the newly commissioned neutron detector array at IUAC are described. The array consists of 100 BC501 liquid scintillators mounted in a semispherical geometry and are kept at a distance of 175 cm from the reaction point. Each detector is a 5″ × 5″ cylindrical cell coupled to 5″ diameter photomultiplier tube (PMT). Signal processing is realized using custom-designed home-made integrated electronic modules which perform neutron–gamma discrimination using zero cross timing and time-of-flight (TOF) technique. Compact custom-built high voltage power supply developed using DC–DC converters are used to bias the detector. The neutrons are recorded in coincidence with fission fragments which are detected using multi-wire proportional counters mounted inside a 1m diameter SS target chamber. The detectors and electronics have been tested off-line using radioactive sources and the results are presented.

    Little is known about the general public's perception of the diagnosis of asthma and the impact of asthma on individuals, their families, and their communities. In addition, there appear to be no published survey instruments specifically designed to gain insights into how the general public perceives asthma. The purpose of this paper is to describe the development of such an instrument, the Chicago Community Asthma Survey (CCAS)-32. Development began with two qualitative steps. First, a review of the published literature guided the initial instrument construction (Step 1). Content domains were chosen based on clinical input and the Health Belief Model. Most items were derived from existing instruments. To assess content validity, cognitive interviews and expert reviews were conducted (Step 2). Items were added, modified, and deleted based on the information gathered at each of these steps. In the next step, item performance measurement (Step 3), testing of two samples provided quantitative data to further inform item reduction. Items with uniform correct responses or responses lacking in variability were excluded. The result of this three-step process was a 32-item survey of asthma knowledge, attitudes and perceptions, the CCAS-32. The introduction to the survey was subsequently modified to minimize respondent bias (Step 4). In conclusion, the CCAS-32 was constructed with input from experts in asthma and individuals from the Chicago area. The items in the CCAS-32 appear to have both face validity and acceptable performance characteristics.

    Full Text Available Cultural competence of healthcare professionals (HCPs is recognized as a strategy to reduce cultural disparities in healthcare. However, standardised, valid and reliable instruments to assess HCPs' cultural competence are notably lacking. The present study aims to 1 identify the core components of cultural competence from a healthcare perspective, 2 to develop a self-report instrument to assess cultural competence of HCPs and 3 to evaluate the psychometric properties of the new instrument.The conceptual model and initial item pool, which were applied to the cross-cultural competence instrument for the healthcare profession (CCCHP, were derived from an expert survey (n = 23, interviews with HCPs (n = 12, and a broad narrative review on assessment instruments and conceptual models of cultural competence. The item pool was reduced systematically, which resulted in a 59-item instrument. A sample of 336 psychologists, in advanced psychotherapeutic training, and 409 medical students participated, in order to evaluate the construct validity and reliability of the CCCHP.Construct validity was supported by principal component analysis, which led to a 32-item six-component solution with 50% of the total variance explained. The different dimensions of HCPs' cultural competence are: Cross-Cultural Motivation/Curiosity, Cross-Cultural Attitudes, Cross-Cultural Skills, Cross-Cultural Knowledge/Awareness and Cross-Cultural Emotions/Empathy. For the total instrument, the internal consistency reliability was .87 and the dimension's Cronbach's α ranged from .54 to .84. The discriminating power of the CCCHP was indicated by statistically significant mean differences in CCCHP subscale scores between predefined groups.The 32-item CCCHP exhibits acceptable psychometric properties, particularly content and construct validity to examine HCPs' cultural competence. The CCCHP with its five dimensions offers a comprehensive assessment of HCPs' cultural competence, and has

    A new polarimeter based on the wedged double Wollaston concept has been built at the Torino Observatory and installed on a 1-m telescope at the Calern observing station of the Observatoire de la Côte d'Azur, France. Its main purpose is to carry out a polarimetric survey of minor Solar system objects, which is called the Calern Asteroid Polarimetric Survey. In this paper, we describe the new Torino polarimeter and the results of preliminary scientific validation tests. A number of standard stars with known polarization states, as well as a number of asteroids for which the polarimetric properties are known, have been observed in order to assess the instrument's accuracy. The instrumental polarization has been found to be stable within a few 10-4 units. A total of 124 new polarimetric observation of 78 asteroids are presented. In the case of asteroids already observed in the past, the new data are in agreement with available phase-polarization curves with error bars smaller than most previously published data. We also present data for 21 asteroids that have never been observed before in polarimetry.

    Student experience surveys have become increasingly popular to probe various aspects of processes and outcomes in higher education, such as measuring student perceptions of the learning environment and identifying aspects that could be improved. This paper reports on a particular survey for evaluating individual experiments that has been developed over some 15 years as part of a large national Australian study pertaining to the area of undergraduate laboratories-Advancing Science by Enhancing Learning in the Laboratory. This paper reports on the development of the survey instrument and the evaluation of the survey using student responses to experiments from different institutions in Australia, New Zealand and the USA. A total of 3153 student responses have been analysed using factor analysis. Three factors, motivation, assessment and resources, have been identified as contributing to improved student attitudes to laboratory activities. A central focus of the survey is to provide feedback to practitioners to iteratively improve experiments. Implications for practitioners and researchers are also discussed.

  9. The development of an instrument to measure the self-efficacy of students participating in VEX robotics competitions

    Robinson, Trevor P.

    The number of robotics competitions has steadily increased over the past 30 years. Schools are implementing robotics competitions to increase student content knowledge and interest in science, technology, engineering, and mathematics (STEM). Companies in STEM-related fields are financially supporting robotics competitions to help increase the number of students pursuing careers in STEM among other reasons. These financial supporters and school administrations are asking what the outcomes of students participating in competitive robotics are. Few studies have been conducted to investigate these outcomes. The studies that have been conducted usually compare students in robotics to students not in robotics. There have not been any studies that compare students to themselves before and after participating in robotics competitions. This may be due to the lack of available instruments to measure student outcomes. This study developed an instrument to measure the self-efficacy of students participating in VEX Robotics Competitions (VRC). The VRC is the world's largest and fastest growing robotics competition available for middle and high school students. Self-efficacy was measured because of its importance to the education community. Students with higher self-efficacy tend to persevere through difficult tasks more frequently than students with low self-efficacy. A person's self-efficacy has major influence over what interests, activities, classes, college majors, and careers he or she will pursue in life. The self-efficacy survey instrument created through this study was developed through an occupational and task analysis (OTA), and initial content and face validity was established through the OTA process. Exploratory and confirmatory factor analyses were also conducted to assist in instrument validation. The reliability was calculated using Cronbach's alpha. Face validity was established through the OTA process. Construct validity was established through the factor

    2014-01-01

    The nature of the clinical learning environment has a huge impact on student learning. This article reviews current methods available for evaluating the clinical learning environment. Five instruments were identified that measure the clinical learning environment. All of these instruments focus solely on the student perspective of the clinical learning environment. Although gaining student input is important, there are other perspectives that offer valuable insights on the nature of the clinical learning environment. The findings from this integrative review indicate the need for future development and testing of an instrument to evaluate the clinical learning environment from the staff nurse and nurse faculty perspective.

    Nurses must competently demonstrate psychomotor skills. Few reliable and valid instruments are available for psychomotor evaluation for disaster skills, including the skill of decontamination. The purpose of this study was to develop and refine an instrument to measure the skill of decontamination. A seven step instrument development design was implemented that included content validity and reliability as well as inter-rater reliability analysis. A convenience sample of approximately 140 participants was drawn from two colleges of nursing at two large academic universities. The sample included senior nursing students in either their community or final practicum nursing course. Based on a sample of 140 students who participated in a decontamination training experience using virtual reality simulation, a seven step established process for assessment of reliability and validity was implemented to develop a checklist for the skill of decontamination. The final instrument statistics: Content Validity Index for the overall instrument score was 0.94, Internal consistency coefficient=0.607(KR-20) and Inter-rater reliability=0.9114. This instrument provides a reliable and valid assessment of nurses' competency in performing the skill of decontamination offering a template for educators to develop similar tools.

    Rural panel surveys are the most appropriate source of data for studying the unprecedented rapid migration and urbanization currently taking place in China and other developing countries. This paper provides a selective review, focusing on the panel survey methodologies of several studies, which are organized based on our proposed four key elements of panel surveys: representativeness, retrospect-prospect, multilevel tracking, and temporality. To maximize heterogeneity in urbanization and development over the last three decades, we select rural panel surveys from five Asian countries: India, Indonesia, Nepal, Thailand, and China. We analyze the strengths and weaknesses of the selected panel surveys to provide directions for designing future rural panel surveys in China and elsewhere in the developing world.

    This study describes the development and psychometric evaluation of HPV Clinical Trial Survey for Parents with Children Aged 9 to 15 (CTSP-HPV) using traditional instrument development methods and community engagement principles. An expert panel and parental input informed survey content and parents recommended study design changes (e.g., flyer wording). A convenience sample of 256 parents completed the final survey measuring parental willingness to consent to HPV clinical trial (CT) participation and other factors hypothesized to influence willingness (e.g., HPV vaccine benefits). Cronbach's a, Spearman correlations, and multiple linear regression were used to estimate internal consistency, convergent and discriminant validity, and predictively validity, respectively. Internal reliability was confirmed for all scales (a ≥ 0.70.). Parental willingness was positively associated (p HPV vaccine benefits, advantages of adolescent CTs (r range 0.33-0.42), supporting convergent validity. Moderate discriminant construct validity was also demonstrated. Regression results indicate reasonable predictive validity with the six scales accounting for 31% of the variance in parents' willingness. This instrument can inform interventions based on factors that influence parental willingness, which may lead to the eventual increase in trial participation. Further psychometric testing is warranted. © 2015 Wiley Periodicals, Inc.

    2015-11-01

    This study is part of a large-scale project focused on 'Qatari students' Interest in, and Attitudes toward, Science' (QIAS). QIAS aimed to gauge Qatari student attitudes toward science in grades 3-12, examine factors that impact these attitudes, and assess the relationship between student attitudes and prevailing modes of science teaching in Qatari schools. This report details the development and validation of the 'Arabic-Speaking Students' Attitudes toward Science Survey' (ASSASS), which was specifically developed for the purposes of the QIAS project. The theories of reasoned action and planned behavior (TRAPB) [Ajzen, I., & Fishbein, M. (2005). The influence of attitudes on behavior. In D. Albarracín, B. T. Johnson, & M. P. Zanna (Eds.), The handbook of attitudes (pp. 173-221). Mahwah, NJ: Erlbaum] guided the instrument development. Development and validation of the ASSASS proceeded in 3 phases. First, a 10-member expert panel examined an initial pool of 74 items, which were revised and consolidated into a 60-item version of the instrument. This version was piloted with 369 Qatari students from the target schools and grade levels. Analyses of pilot data resulted in a refined version of the ASSASS, which was administered to a national probability sample of 3027 participants representing all students enrolled in grades 3-12 in the various types of schools in Qatar. Of the latter, 1978 students completed the Arabic version of the instrument. Analyses supported a robust, 5-factor model for the instrument, which is consistent with the TRAPB framework. The factors were: Attitudes toward science and school science, unfavorable outlook on science, control beliefs about ability in science, behavioral beliefs about the consequences of engaging with science, and intentions to pursue science.

  17. The Statistics Concept Inventory: Development and analysis of a cognitive assessment instrument in statistics

    Science.gov (United States)

    Allen, Kirk

    The Statistics Concept Inventory (SCI) is a multiple choice test designed to assess students' conceptual understanding of topics typically encountered in an introductory statistics course. This dissertation documents the development of the SCI from Fall 2002 up to Spring 2006. The first phase of the project essentially sought to answer the question: "Can you write a test to assess topics typically encountered in introductory statistics?" Book One presents the results utilized in answering this question in the affirmative. The bulk of the results present the development and evolution of the items, primarily relying on objective metrics to gauge effectiveness but also incorporating student feedback. The second phase boils down to: "Now that you have the test, what else can you do with it?" This includes an exploration of Cronbach's alpha, the most commonly-used measure of test reliability in the literature. An online version of the SCI was designed, and its equivalency to the paper version is assessed. Adding an extra wrinkle to the online SCI, subjects rated their answer confidence. These results show a general positive trend between confidence and correct responses. However, some items buck this trend, revealing potential sources of misunderstandings, with comparisons offered to the extant statistics and probability educational research. The third phase is a re-assessment of the SCI: "Are you sure?" A factor analytic study favored a uni-dimensional structure for the SCI, although maintaining the likelihood of a deeper structure if more items can be written to tap similar topics. A shortened version of the instrument is proposed, demonstrated to be able to maintain a reliability nearly identical to that of the full instrument. Incorporating student feedback and a faculty topics survey, improvements to the items and recommendations for further research are proposed. The state of the concept inventory movement is assessed, to offer a comparison to the work presented

    To develop and perform psychometric testing on an instrument designed to assess cognitive/emotional responses among men receiving HPV testing. Men enrolled in an HPV natural history study (N = 139) completed a computer-assisted survey instrument based on Leventhal's parallel processing/common-sense model. Data were analyzed using SPSS and Mplus. Reliability analyses resulted in Cronbach alpha of 0.72 (knowledge), 0.86 (perceived threat), 0.83 (self-efficacy), and 0.55 (response efficacy). A revised measurement model exhibited evidence of construct validity, as indicated by acceptable model fit statistics. To our knowledge, this is the only validated instrument assessing men's reactions to an HPV test result.

    For the enforcement of the {rho}a-{rho}u survey method which is a type of high-density electrical survey, a multichannel resistivity measuring instrument has been developed. This instrument, in addition to the above, conducts resistivity tomography and various other kinds of high-density electrical survey. A potential produced by a low frequency rectangular current of 1Hz or lower outputted by the transmitter of this instrument is received and measured by the receiver connected to electrodes positioned at 100 or less locations. The receiver comprises a scanner that automatically switches from electrode to electrode, conditioner that processes signals, and controller. A transmitter of the standard design outputs a maximum voltage of 800V and maximum current of 2A, making a device suitable for probing 50 to several 100m-deep levels. The receiver is operated by a personal computer that the controller is provided with. The newly-developed apparatus succeeded in presenting high-precision images of the result of a {rho}a-{rho}u analysis for an apparent resistivity section and of the underground structure, verifying the high quality of the data collected by this apparatus. 10 refs., 5 figs., 1 tab.

    The ocean-energy industry is still in its infancy and device developers have provided their own equipment and procedures for testing. Currently, no testing standards exist for ocean energy devices in the United States. Furthermore, as prototype devices move from the test tank to in-water testing, the logistical challenges and costs grow exponentially. Development of a common instrumentation package that can be moved from device to device is one means of reducing testing costs and providing normalized data to the industry as a whole. As a first step, the U.S. National Renewable Energy Laboratory (NREL) has initiated an effort to develop an instrumentation package to provide a tool to allow common measurements across various ocean energy devices. The effort is summarized in this paper. First, we present the current status of ocean energy devices. We then review the experiences of the wind industry in its development of the instrumentation package and discuss how they can be applied in the ocean environment. Next, the challenges that will be addressed in the development of the ocean instrumentation package are discussed. For example, the instrument package must be highly adaptable to fit a large array of devices but still conduct common measurements. Finally, some possible system configurations are outlined followed by input from the industry regarding its measurement needs, lessons learned from prior testing, and other ideas.

    More than a decade ago, due to obsolescence issues, ESO initiated the design and implementation of a custom-made CANbus based motion controller (CAN-RMC) to provide, together with a tailor-made software library (motor library), the motion control capabilities for the VME platform needed for the second generation VLT/VLTI instruments. The CAN-RMC controller has been successfully used in a number of VLT instruments but it has high production costs compared to the commercial off-the-shelf (COTS) industrial solutions available on the market today. In the scope of the selection of a new PLC-based platform for the VLT instrument control systems, ESO has evaluated motion control solutions from the company Beckhoff. This paper presents the investigation, implementation and testing of the PLC/TwinCAT/EtherCAT motion controllers for DC and stepper motors and their adaptation and integration into the VLT instrumentation framework. It reports functional and performance test results for the most typical use cases of astronomical instruments like initialization sequences, tracking, switch position detections, backslash compensation, brake handling, etc. In addition, it gives an overview of the main features of TwinCAT NC/PTP, PLCopen MC, EtherCAT motion control terminals and the engineering tools like TwinCAT Scope that are integrated into the development environment and simplify software development, testing and commissioning of motorized instrument functions.

    2011-06-01

    Recently, with advances in computer technologies, Internet cancer support groups became more popular than ever among people living with cancer. However, there is little information available on cancer patients' use of Internet cancer support groups, which may be partially due to a lack of instruments measuring cancer patients' use of Internet cancer support groups. Indeed, virtually no instrument measuring cancer patients' use of Internet cancer support groups can be identified through searches using multiple databases. In this study, a new instrument measuring the use of Internet cancer support groups was developed, and its psychometric properties were tested among 117 people living with cancer recruited through the Internet using a convenience sampling method. First, the development process of the new instrument, the Questions on the Use of Internet Cancer Support Groups, is described. Then, the pilot study on psychometric properties of the instrument is presented. Reliability was evaluated using internal consistency reliability testing, split-half reliability testing, and item analysis. Validity was assessed by using criterion validity, convergent validity, and face validity. The findings of the pilot study supported the reliability and validity of this new instrument. Based on the findings, some implications for future research are proposed.

    Full Text Available Abstract Background To increase the effectiveness of quality-improvement collaboratives (QICs, it is important to explore factors that potentially influence their outcomes. For this purpose, we have developed and tested the psychometric properties of an instrument that aims to identify the features that may enhance the quality and impact of collaborative quality-improvement approaches. The instrument can be used as a measurement instrument to retrospectively collect information about perceived determinants of success. In addition, it can be prospectively applied as a checklist to guide initiators, facilitators, and participants of QICs, with information about how to perform or participate in a collaborative with theoretically optimal chances of success. Such information can be used to improve collaboratives. Methods We developed an instrument with content validity based on literature and the opinions of QIC experts. We collected data from 144 healthcare professionals in 44 multidisciplinary improvement teams participating in two QICs and used exploratory factor analysis to assess the construct validity. We used Cronbach's alpha to ascertain the internal consistency. Results The 50-item instrument we developed reflected expert-opinion-based determinants of success in a QIC. We deleted nine items after item reduction. On the basis of the factor analysis results, one item was dropped, which resulted in a 40-item questionnaire. Exploratory factor analysis showed that a three-factor model provided the best fit. The components were labeled 'sufficient expert team support', 'effective multidisciplinary teamwork', and 'helpful collaborative processes'. Internal consistency reliability was excellent (alphas between .85 and .89. Conclusions This newly developed instrument seems a promising tool for providing healthcare workers and policy makers with useful information about determinants of success in QICs. The psychometric properties of the instrument are

    The framework for teaching and learning in the 21st century was prepared with 4Cs criteria. Learning providing opportunity for the development of students' optimal creative skills is by implementing collaborative learning. Learners are challenged to be able to compete, work independently to bring either individual or group excellence and master the learning material. Virtual laboratory is used for the media of Instrumental Analytical Chemistry (Vis, UV-Vis-AAS etc) lectures through simulations computer application and used as a substitution for the laboratory if the equipment and instruments are not available. This research aims to design and develop collaborative-creative learning model using virtual laboratory media for Instrumental Analytical Chemistry lectures, to know the effectiveness of this design model adapting the Dick & Carey's model and Hannafin & Peck's model. The development steps of this model are: needs analyze, design collaborative-creative learning, virtual laboratory media using macromedia flash, formative evaluation and test of learning model effectiveness. While, the development stages of collaborative-creative learning model are: apperception, exploration, collaboration, creation, evaluation, feedback. Development of collaborative-creative learning model using virtual laboratory media can be used to improve the quality learning in the classroom, overcome the limitation of lab instruments for the real instrumental analysis. Formative test results show that the Collaborative-Creative Learning Model developed meets the requirements. The effectiveness test of students' pretest and posttest proves significant at 95% confidence level, t-test higher than t-table. It can be concluded that this learning model is effective to use for Instrumental Analytical Chemistry lectures.

    The aim of this study was to describe the initial stages of the cross-cultural adaptation of the instrument The Vulnerable Elders Survey (VES-13) for use in the context of cancer care in Brazil. Two translations into Portuguese and two back-translations into English were carried out independently, and a formal assessment of the general and referential meanings was performed in order to obtain a synthesis version. Understanding of the synthesis version was evaluated in a pretest applied to 33 patients in an oncologic hospital of the Brazilian Unified National Health System (SUS). The version was easily applied in the intended context and was well-accepted by elders. The Portuguese version of the VES-13 proved to be well understood and adequate for testing its psychometric qualities. The latter step is currently in the final phase.

    2010-01-01

    We present the progress toward an analytical performance model of a 2.3 micron infrared correlation radiometer (IRCRg) prototype subsystem for a future geostationary space-borne instrument. The prototype is designed specifically to measure carbon monoxide (CO) from geostationary orbit. NASA's Geostationary Coastal and Air Pollution Events (GEO-CAPE) mission, one of the United States Earth Science and Applications Decadal Survey missions, specifies the use of infrared correlation radiometry to measure CO in two spectral regions for this mission. GEO-CAPE will use the robust IRCR measurement technique at geostationary orbit, nearly 50 times farther away than the Terra/MOPITT orbit, to determine hourly changes in CO across a continental domain. The abundance of CO in Earth's troposphere directly affects the concentration of hydroxyl, which regulates the lifetimes of many tropospheric pollutants. In addition, CO is a precursor to ozone formation; CO is used as a tracer to study the transport of global and regional pollutants; and CO is used as an indicator of both natural and anthropogenic air pollution sources and sinks. We have structured our development project to enable rapid evaluation of future spaceborne instrument designs. The project is part of NASA's Instrument Incubator Program. We describe the architecture of the performance model and the planned evaluation of the performance model using laboratory test data.

    To develop an observational coding instrument for evaluating the fidelity and quality of brief behavioral change interventions based on the behavioral theories of the 5 A's, Stages of Change and Motivational Interviewing. Content and face validity were assessed prior to an intervention where psychometric properties were evaluated with a prospective cohort of 116 medical students. Properties assessed included the inter-rater reliability of the instrument, internal consistency of the full scale and sub-scales and descriptive statistics of the instrument. Construct validity was assessed based on student's scores. Inter-rater reliability for the instrument was 0.82 (intraclass correlation). Internal consistency for the full scale was 0.70 (KR20). Internal consistencies for the sub-scales were as follows: MI intervention component (KR20=.7); stage-appropriate MI-based intervention (KR20=.55); MI spirit (KR20=.5); appropriate assessment (KR20=.45) and appropriate assisting (KR20=.56). The instrument demonstrated good inter-rater reliability and moderate overall internal consistency when used to assess performing brief behavioral change interventions by medical students. This practical instrument can be used with minimal training and demonstrates promising psychometric properties when evaluated with medical students counseling standardized patients. Further testing is required to evaluate its usefulness in clinical settings. Copyright © 2010 Elsevier Ireland Ltd. All rights reserved.

  19. Development of a survey to assess adolescent perceptions of teen parenting.

    Herrman, Judith W; Nandakumar, Ratna

    2012-01-01

    Initiatives designed to prevent teen pregnancy are often based on adult perceptions of the negative aspects of a teen birth. Qualitative research has revealed that teens may perceive positive rewards associated with teen parenting. These perceptions have not yet been examined through survey research. The theory of reasoned action proposes that individuals assess the costs and rewards prior to engaging in a behavior and provides a framework for the development of a survey instrument designed to measure adolescent thoughts about the costs and rewards of the teen parenting experience. This manuscript describes the development and testing of a quantitative survey instrument designed to measure adolescents' perceptions. Pretesting, piloting, exploratory factor analysis, and a variety of reliability and validity measures were used to determine the value of the measure. The thoughts on teen parenting survey (TTPS) demonstrates an alpha level of .90. The TTPS yields a cumulative score of teen perceptions about the impact of a teen birth during the adolescent years that may be used to assess youth beliefs, correlated with demographic data, used to identify teens at risk for pregnancy/parenting, or provide a pretest/posttest to assess the effectiveness of interventions designed to foster realistic attitudes toward teen parenting.

    2016-06-01

    Full Text Available The objective of the research was to adapt for use in Russian-language contexts a set of instruments that assess the effectiveness of psychotherapeutic practices. The instruments explore the effectiveness of different types of therapy, without evaluating the abstract, idealized characteristics or specifics of each approach, specialist, or therapeutic case. The adapted instruments are based on reflective data about the significance of therapeutic events, from the point of view of both the client and the therapist. We translated, edited, and adapted forms developed by John McLeod and Mick Cooper — a “Goals Form”, a “Goal Assessment Form”, a “Post-Session Form”, and a “Therapy Personalization Form”. The adaption was intended to cohere with the stylistic and cultural aspects of the Russian language. The research showed that the instruments and the methods have great potential for practical and theoretical application in qualitative studies to formulate hypotheses and to verify them in quantitative studies. The phenomenological analysis reveals the reliability, appropriateness, and validity of the adapted instruments for identifying specific meanings of the psychotherapeutic cases considered. The instruments can be used in studies exploring helpful aspects and effectiveness in different types of therapy (cognitive, existential, outdoor therapy, online counseling, etc. with different groups of clients. It is reasonable to continue the use of the Russian-language version of the instruments in further studies exploring the effectiveness of psychological practices. The adapted instruments facilitate comparison and cross-cultural studies, and formulation of meaningful hypotheses about the effectiveness and quality of the psychotherapeutic process.

    The intensification of the greenhouse effect, caused mainly by the anthropogenic activities, such as the intensive use of fossil fuels, reveals itself as a challenge to governments and international organizations. The institution of an international legal framework, resulted from the implementation of the United Nations Framework Convention on Climate Change and the Kyoto Protocol, is allowing the development of some mitigation instruments, such as the clean development mechanism (CDM). The article's purpose is to assess the social and economic aspects that are leading to the climate change process and to analyze the instruments foreseen in the international legal system to face this global concern, in special, the CDM as a tool to achieve sustainable development practices. In this way, the authors aims to demonstrate the connection and interdependence between those instruments and the sustainable development. (author)

    2011-08-01

    Full Text Available Abstract Background Measures that reflect patients' assessment of their health are of increasing importance as outcome measures in randomised controlled trials. The methodological approach used in the pre-validation development of new instruments (item generation, item reduction and question formatting should be robust and transparent. The totality of the content of existing PRO instruments for a specific condition provides a valuable resource (pool of items that can be utilised to develop new instruments. 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

    Little is known about the prevalence, severity, or impact of symptoms in hemodialysis patients because of the lack of a validated symptom assessment instrument. We systematically developed an index to assess physical and emotional symptom burden in this patient population. We employed four steps in the generation of this index: a review of dialysis quality-of-life instruments, three focus groups, experts' content validity assessment, and test-retest reliability measurement. Seventy-five symptoms were identified. Of these, 46 appeared in > or = 4 of the instruments/focus groups and were considered for inclusion. Twelve were grouped into other symptom constructs and experts judged four of the remaining items not to be pertinent, leaving 30 items in the new index. Overall kappa statistic was 0.48+/-0.22. These steps allowed the systematic development of a 30-item symptom assessment index for hemodialysis patients. Additional reliability and validity testing is needed prior to its widespread use.

By utilizing instantaneous frequency estimation (IFE) theoretics of TFA technique, and based on IFE of peak searching on the time-frequency spectrum, order analysis (OA) functions is put forward and implemented, such as order spectrum, order spectrum matrix, order tracking, order tracking filtering, and order component extraction, etc. Unlike the home and abroad existing popular characteristic analyzers, which need key phasing devices such as shaft encoder, phase-locked loop (PLL), phase-locked multiple frequency, tachometer, etc, to implement constant angle sampling directly or indirectly, whereas this instrument only uses the vibration signal of rotating machinery to carry out OA. This instrument makes up the shortage of these traditional instruments in analyzing the non-stationary signal of run-up and run-down process of rotating machinery. Therefore, it is a great breakthrough for the existing order analyzers.

    Near infrared spectroscopy (NIRS) is an established technology using photons of light in the near infrared spectrum to monitor changes in tissue of naturally occurring chromophores, including oxygenated and deoxygenated hemoglobin. Technology and methodology have been validated for measurement of a range of physiologic parameters. NIRS has been applied successfully in urology research; however current instruments are designed principally for brain and muscle study. To describe development of a NIRS instrument specifically designed for monitoring changes in chromophore concentration in the bladder detrusor in real time, to facilitate research to establish the role of this non-invasive technology in the evaluation of patients with voiding dysfunction The portable continuous wave NIRS instrument has a 3 laser diode light source (785, 808 and 830 nanometers), fiber optic cables for light transmission, a self adhesive patient interface patch with an emitter and sensor, and software to detect the difference between the light transmitted and received by the instrument. Software incorporated auto-attenuates the optical signals and converts raw optical data into chromophore concentrations displayed graphically. The prototype was designed, tested, and iteratively developed to achieve optimal suprapubic transcutaneous monitoring of the detrusor in human subjects during bladder filling and emptying. Evaluation with simultaneous invasive urodynamic measurement in men and women indicates good specificity and sensitivity of NIRS chromophore concentration changes by receiver operator curve analysis, and correlation between NIRS data and urodynamic pressures. Urological monitoring with this NIRS instrument is feasible and generates data of potential diagnostic value.

    The town of Mesagne is one of the sites at greatest geological risk in the north Salento peninsula. In the last few decades, the historical centre of Mesagne has been affected by a series of subsidence events, which have, in some cases, resulted in the partial collapse of buildings and road surfaces. The last event was in the January 2014. It caused subsidence phenomenon in a wide area and many families have been forced from their homes. These events have had both social repercussions, causing alarm and emergency situations, and economic repercussions in terms of the expense of restoration. In order to determine the causes of the ground subsidence events, integrated geophysical surveys were undertaken in the historical centre of Mesagne. In addition, the analysis of several wells allowed the 3D model reconstruction related both to the geology and to the groundwater depth in the surveyed areas. With the purpose of estimating the dimensions of the phenomenon and its possible relationship with both specific environmental conditions (for instance groundwater depth variation) and anthropic conditions (for instance the losses in water supply and sanitation) some geophysical measurements were repeated in the time. For this purpose a modified ERT instrumentation together GPR were used. The study led to the production of a detailed description of the subsidence causes that allows a quick action to restore security conditions in the area.

    Unmet spiritual needs have been associated with decreased patient ratings of quality of care, satisfaction, and quality of life. There is a need for a well-validated, psychometrically sound instrument to describe and measure spiritual needs. To develop a valid and reliable instrument to assess patients' spiritual needs. Instrument development was based on a literature review, clinical and pastoral evaluation, and cognitive pretesting (n=15 ambulatory cancer patients). Forty-seven ambulatory cancer patients completed cross-sectional and longitudinal surveys to test instrument validity and reliability. Internal reliability was assessed by Cronbach's α, test-retest reliability by Spearman's correlation coefficients, and construct validity by comparing instrument scores to a previously used single-item spiritual needs question. The Spiritual Needs Assessment for Patients (SNAP) comprises a total of 23 items in three domains: psychosocial (n=5), spiritual (n=13), and religious (n=5). Sixty percent of participants were white, 21% black, 13% Hispanic, and 6% Asian or other. Fifty-eight percent were Catholic, 13% Jewish, 11% Protestant, 2% Buddhist, 2% Muslim, and 2% Hindu. Sixty-eight percent described themselves as spiritual but not religious; 15% reported unmet spiritual needs; 19% wanted help meeting their spiritual needs. Cronbach's α for the total SNAP was 0.95, and for the subscales was psychosocial=0.74, spiritual=0.93, and religious needs=0.86. Test-retest correlation coefficients were total SNAP=0.69, psychosocial needs=0.51, spiritual needs=0.70, and religious needs=0.65. Participants reporting unmet spiritual needs had significantly higher mean scores on the total SNAP (66.3 vs. 49.4, P=0.03) and on the spiritual needs subscale (39.0 vs. 28.3, P=0.02). The results provide preliminary evidence that the SNAP is a valid and reliable instrument for measuring spiritual needs in a diverse patient population.

    Full Text Available Applications and practices of interactive whiteboards (IWBs in school learning is important focus and development trend for developmented countries in recent years. There are rare researches and discussions about IWB teaching materials for course teaching and teaching effectiveness. As for the aspect of academic studies, there is more practical teaching sharing for subjects such as language learning, mathematical learning and physical science learning; however, it is rarely seen empirical research on the application of IWB for educational acceptances of interactive whiteboards. Based on its imporatances, we summarize previous literatures to establish a theoretical model for interactive whiteboards (IWBs. Variables in this model are then discussed to find out the interaction between each other. The contribution of the study develops an innovative model for educational acceptances of interactive whiteboards using hybrid TAM, ECM, and Flow models.

    Barrado, David; Gallego, Jesús

    2009-12-01

    The answers to the present astrophysical questions require the development of highly sophisticated instrumentation, which needs long-term scheduling and large assets of human and material resources, managed by consortia of several institutions. Spain has carried in the last years serious efforts in this direction (GTC, ESO, ESA), but there is still a notable offset between astronomical research at the theoretical and observational levels and the development of instrumentation. Now, the incorporation of new countries to ESO (in particular Spain) to ESO and several future big projects (ALMA, E-ELT, Cosmic Vision), raise the level of exigency. The goal of this workshop is to gather the scientific teams and the industries of the sector to expose their needs and projects, and share experiences. The workshop is aimed as well at serving as an echo to convince financing agencies and the astronomical community in general of the need to promote with decision the development of astrophysical instrumentation and the tools for the analysis of related data. The formation and acknowledgement of instrumentation astronomers will be a key factor for Spain to meet the requirements of its position in Astronomy in the next decades. Here, we present the contributions most closely related to the development of E-ELT, ALMA and ESA missions.

    Directors in substance use treatment programs are increasingly required to respond to external economic and socio-political pressures. Leadership practices that promote innovation can help offset these challenges. Using focus groups, factor analysis, and validation instruments, the current study developed and established psychometrics for the Survey of Transformational Leadership. In 2008, clinical directors were evaluated on leadership practices by 214 counselors within 57 programs in four U.S. regions. Nine themes emerged: integrity, sensible risk, demonstrates innovation, encourages innovation, inspirational motivation, supports others, develops others, delegates tasks, and expects excellence. Study implications, limitations and suggested future directions are discussed. Funding from NIDA. PMID:20509734

  11. Development and Testing of an Optimised Combined Analytical Instrument for Planetary Applications

    Lerman, Hannah; Hutchinson, Ian

    2016-10-01

    Miniaturised, analytical instruments that can simultaneously obtain complementary (molecular and elemental) information about the composition of a sample are likely to be a key feature of the next generation of planetary exploration missions. Certain spectroscopic techniques, such as Raman spectroscopy, can provide information on the molecular composition of an unknown sample whereas others, such as Laser-Induced Breakdown Spectroscopy (LIBS) and X-Ray Fluorescence (XRF), enable the determination of the elemental composition of a material. Combining two or more of these techniques into one instrument package enables a broader range of the scientific goals of a particular mission to be obtained (i.e. full composition analysis and structural information about the sample and therefore geological history). In order to determine the most appropriate design for such an instrument, we have developed some radiometric models to assess the overall scientific capability of various analytical technique combinations. We have then used these models to perform a number of trade-offs to evaluate the optimum instrument design for a particular set of science requirements (such as, to acquire composition information with suitable sensitivity and uncertainty). The performance of one of these designs was then thoroughly investigated by building a prototype instrument. The construction of our instrument focuses on the optimum design for combining the multiple instrument sub-systems so that the overall mass, power and cost budgets can be minimised, whilst achieving the wider and more comprehensive range of scientific goals. Here we report on measurements obtained from field test campaigns that have been performed in order to verify model predictions and overall scientific performance. These tests include operation in extreme environments such as dry deserts and under water.

    The Savannah River National Laboratory (SRNL) has developed prototype equipment to demonstrate remote surveying of Inner and Outer DOE Standard 3013 containers for fixed and transferable contamination in accordance with DOE Standard 3013 and 10 CFR 835 Appendix B. When fully developed the equipment will be part of a larger suite of equipment used to package material in accordance with DOE Standard 3013 at the Pit Disassembly and Conversion Project slated for installation at the Savannah River Site. The prototype system consists of a small six-axis industrial robot with an end effector consisting of a force sensor, vacuum gripper and a three fingered pneumatic gripper. The work cell also contains two alpha survey instruments, swipes, swipe dispenser, and other ancillary equipment. An external controller interfaces with the robot controller, survey instruments and other ancillary equipment to control the overall process. SRNL is developing automated equipment for the Pit Disassembly and Conversion (PDC) Project that is slated for the Savannah River Site (SRS). The equipment being developed is automated packaging equipment for packaging plutonium bearing materials in accordance with DOE-STD-3013-2004. The subject of this paper is the development of a prototype Radiological Survey Station (RSS). Other automated equipment being developed for the PDC includes the Bagless transfer System, Outer Can Welder, Gantry Robot System (GRS) and Leak Test Station. The purpose of the RSS is to perform a frisk and swipe of the DOE Standard 3013 Container (either inner can or outer can) to check for fixed and transferable contamination. This is required to verify that the contamination levels are within the limits specified in DOE-STD-3013-2004 and 10 CFR 835, Appendix D. The surface contamination limit for the 3013 Outer Can (OC) is 500 dpm/100 cm2 (total) and 20 dpm/100 cm2 (transferable). This paper will concentrate on the RSS developments for the 3013 OC but the system for the

    2013-08-01

    Following a search conducted in several databases, no instrument was found that jointly evaluates the prevalence of back pain and its associated demographic, social-economic, hereditary, behavioral and postural risk factors. Thus, the present study aims to develop the Back Pain and Body Posture Evaluation Instrument (BackPEI) for school-age children and verify its validity and reproducibility. Twenty-one questions were elaborated to compose the BackPEI instrument, eight experts checked the content validity, and its reproducibility was tested by applying the questionnaire to 260 primary schoolchildren, at two different times with a 7-day interval. The reproducibility data for the first 20 questions, analyzed using the kappa (k) coefficient, were classified as "very good" (k > 0.8) or "good" (0.6 back pain and its associated risk factors.

    2006-09-01

    This article describes the development and field test of an instrument, the Views on Science and Education Questionnaire, designed to measure participants' concepts of the nature of science (NOS) and relevant teaching attitudes. The questionnaire includes 15 questions, each followed by several items representing different philosophical positions. Participants rank each item on a five-point scale. The items were empirically based and described from the learners' perspectives, but the issues and subcategories covered were validated by a panel of experts. The latest version was administered to 302 college students. Combined conceptions and conflicting thoughts about NOS were detected. Furthermore, the instrument achieved a test-retest correlation coefficient of 0.82. The questionnaire is a valid and practical tool that can be used to determine participants' conceptions and attitudes toward teaching NOS. With this instrument, science educators and teachers can conduct comparison studies and relate views of NOS to other measurable educational outcomes.

    Scientific ground-truth measurements for near-term Mars missions, such as the 2009 Mars Science Laboratory (MSL) mission, are essential for validating current in situ flight instrumentation and for the development of advanced instrumentation technologies for life-detection missions over the next decade. The NASA Astrobiology Institute (NAI) has recently funded a consortium of researchers called the Astrobiology Sample Analysis Program (ASAP) to analyze an identical set of homogenized martian analog materials in a "round-robin" style using both state-of-the-art laboratory techniques as well as in-situ flight instrumentation including the SAM gas chromatograph mass spectrometer and CHEMIN X-ray diffraction/fluorescence instruments on MSL and the Urey and MOMA organic analyzer instruments under development for the 2013 ExoMars missions. The analog samples studied included an Atacama Desert soil from Chile, the Murchison meteorite, a gypsum sample from the 2007 AMASE Mars analog site, jarosite from Panoche Valley, CA, a hydrothermal sample from Rio Tinto, Spain, and a "blind" sample collected during the 2007 MSL slow-motion field test in New Mexico. Each sample was distributed to the team for analysis to: (1) determine the nature and inventory of organic compounds, (2) measure the bulk carbon and nitrogen isotopic composition, (3) investigate elemental abundances, mineralogy and matrix, and (4) search for biological activity. The experimental results obtained from the ASAP Mars analog research consortium will be used to build a framework for understanding the biogeochemistry of martian analogs, help calibrate current spaceflight instrumentation, and enhance the scientific return from upcoming missions.

    Dunbar, Terry Frank

    The use of the scientific inquiry method of teaching science was investigated in one district's elementary schools. The study generated data directly from Albuquerque Public Schools fourth- and fifth-grade teachers through a mail-out survey and through observation. Two forms of an inquiry evaluation research instrument (Elementary Science Inquiry Survey - ESIS) were created. The ESIS-A is a classroom observation tool. The ESIS-B is a survey questionnaire designed to collect information from teachers. The study was designed first to establish reliability and validity for both forms of the instrument. The study made use of multiple regression and exploratory factor analysis. Sources used to establish the instruments' reliability and validity included: (1) Input from an international panel (qualitative analysis of comments sent by raters and quantitative analysis of numerical ratings sent by raters); (2) Cronbach's alpha; (3) Results of factor analysis; (4) Survey respondents' comments (qualitative analysis); (5) Teacher observation data. Cronbach's alpha for the data set was .8955. Inquiry practices were reported to occur between twice per week and three times per week. Teachers' comments regarding inquiry were reported. The ESIS was used to collect inquiry self-report data and teacher background data. The teacher background data included teacher science knowledge and information about their standards awareness and implementation. The following teacher knowledge factors were positively correlated with inquiry use: semesters of college science, science workshops taken, conducted scientific research, and SIMSE (NSF institute) participation. The following standards awareness and implementation factors were positively correlated with inquiry use: familiarity with the National Science Education Standards, familiarity with New Mexico science standards, state or national standards as a curriculum selection factor, student interest as a curriculum selection factor, and "no

    Full Text Available Abstract Background A frailty paradigm would be useful in primary care to identify older people at risk, but appropriate metrics at that level are lacking. We created and validated a simple instrument for frailty screening in Europeans aged ≥50. Our study is based on the first wave of the Survey of Health, Ageing and Retirement in Europe (SHARE, http://www.share-project.org, a large population-based survey conducted in 2004-2005 in twelve European countries. Methods Subjects: SHARE Wave 1 respondents (17,304 females and 13,811 males. Measures: five SHARE variables approximating Fried's frailty definition. Analyses (for each gender: 1 estimation of a discreet factor (DFactor model based on the frailty variables using LatentGOLD®. A single DFactor with three ordered levels or latent classes (i.e. non-frail, pre-frail and frail was modelled; 2 the latent classes were characterised against a biopsychosocial range of Wave 1 variables; 3 the prospective mortality risk (unadjusted and age-adjusted for each frailty class was established on those subjects with known mortality status at Wave 2 (2007-2008 (11,384 females and 9,163 males; 4 two web-based calculators were created for easy retrieval of a subject's frailty class given any five measurements. Results Females: the DFactor model included 15,578 cases (standard R2 = 0.61. All five frailty indicators discriminated well (p N = 10,420; 66.9%, pre-frail (N = 4,025; 25.8%, and frail (N = 1,133; 7.3%. Relative to the non-frail class, the age-adjusted Odds Ratio (with 95% Confidence Interval for mortality at Wave 2 was 2.1 (1.4 - 3.0 in the pre-frail and 4.8 (3.1 - 7.4 in the frail. Males: 12,783 cases (standard R2 = 0.61, all frailty indicators had p N = 10,517; 82.3%, pre-frail (N = 1,871; 14.6%, and frail (N = 395; 3.1%; age-adjusted OR (95% CI for mortality: 3.0 (2.3 - 4.0 in the pre-frail, 6.9 (4.7 - 10.2 in the frail.

    Identifying students' conceptual scientific understanding is difficult if the appropriate tools are not available for educators. Concept inventories have become a popular tool to assess student understanding; however, traditionally, they are multiple choice tests. International science education standard documents advocate that assessments should be reform based, contain diverse question types, and should align with instructional approaches. To date, no instrument of this type targeting student conceptions in biotechnology has been developed. We report here the development, testing, and validation of a 35-item Biotechnology Instrument for Knowledge Elicitation (BIKE) that includes a mix of question types. The BIKE was designed to elicit student thinking and a variety of conceptual understandings, as opposed to testing closed-ended responses. The design phase contained nine steps including a literature search for content, student interviews, a pilot test, as well as expert review. Data from 175 students over two semesters, including 16 student interviews and six expert reviewers (professors from six different institutions), were used to validate the instrument. Cronbach's alpha on the pre/posttest was 0.664 and 0.668, respectively, indicating the BIKE has internal consistency. Cohen's kappa for inter-rater reliability among the 6,525 total items was 0.684 indicating substantial agreement among scorers. Item analysis demonstrated that the items were challenging, there was discrimination among the individual items, and there was alignment with research-based design principles for construct validity. This study provides a reliable and valid conceptual understanding instrument in the understudied area of biotechnology.

    The aim of the current study was to develop an instrument to determine the professional attitude of nursing students. The data were collected through a scale developed by the authors with the statements on attitude, including 8 sub-groups and 28 items. This was a Likert-type scale, ranging from 5 to 1. The sampling of the investigation comprised 1339 final-year undergraduate nursing students in Turkey. Eight factors were defined depending on the reliability and validity study of the professionalism instrument for nursing students. These factors accounted for 65.5% of the total variance. The correlation of the sub-factors in the scale ranged from 0.71 to 0.84. Cronbach alpha value was 0.90 and Cronbach alpha coefficient for sub-factors was between 0.71 and 0.84. Item test correlations calculated for the validity and the homogeneity of the instrument's items were between 0.30 and 0.63. In conclusion, it was found that the instrument was a valid and reliable assessment tool that can be used to measure professional attitudes of nursing students. Copyright © 2010 Elsevier Ltd.

    The importance of educating dental students in cultural competence has been widely emphasized, but there is a need to assess cultural competence in a consistent and reliable way. The aims of this study were to determine latent constructs for the initial measure of cultural competence for oral health providers, the Knowledge, Efficacy, and Practices Instrument (KEPI), and to determine how well these factors related to previously identified latent constructs. Data were collected in surveys of dental students and from dental hygiene, dental assisting, and dental faculty members in 44 academic dental institutions from 2012 to 2015. There were a total of 1,786 respondents to the surveys; response rates to individual surveys ranged from 35% to 100%. There were 982 (55%) female and 804 (45%) male respondents, 286 (16%) underrepresented minority (URM) and 1,500 (84%) non-URM respondents, and 339 (19%) faculty and 1,447 (81%) student respondents. Three latent constructs were identified. Female respondents scored significantly higher on the culture-centered practice and efficacy of assessment factors, while URM respondents had significantly higher scores on all three of the KEPI factors. Measurements indicated that the long-form KEPI could be shortened by ten questions and still have three meaningful measurements. Continued research in assessing other health care providers' cultural competence is needed to expand the KEPI to measure providers' cultural competence with patients with minority sexual orientation and gender identity issues and those with physical disabilities, mental illness, and autism to advance patient-centric communication.

    Spirituality is receiving increased attention in the context of the workplace. Research consistently shows that spirituality is significantly correlated with mental health and well-being. Most of the research on spirituality, particularly in the context of the workplace, is conducted with instruments developed in the USA. However, the inter-cultural measurement of constructs remains a concern, because instruments developed in one culture are not necessarily transferable to another culture. In the current study, the transferability of two spiritual measures developed in the USA, namely the Human Spirituality Scale (HSS) and the Organizational Spirituality Values Scale (OSVS) are considered for a sample from South Africa. The results confirm the construct validity of the HSS and the OSVS, but indicate that the factor structures of the HSS and the OSVS should be analysed and reconfirmed when used, particularly in a South African sample. The study provides evidence that the HSS and the OSVS cannot be transferred indiscriminately to a South African sample. This insight contributes to the quality of future research studies in South Africa, not only on the important aspect of spirituality, but also when applying instruments developed elsewhere in the world.

    Full Text Available The first aim of this study is to investigate whether instruments developed with an emic approach in Turkey produce the same trait-value links obtained with studies using near universal instruments, and if emic traits and value concepts are composed under agency and communal conceptions. So, the first aim of this study is to inspect the conceptual similarities in the links between traits and values. The second aim is to examine the moderating effect of disposable income on the strength of the trait-value relationship. Undergraduate and graduate students (N = 595 from six universities in Istanbul responded to the Personality Profile Scale (PPS and the Life Goal Values (LGV questionnaire. Second order factor analysis indicated that indigenous value and trait items were representative of communal and agency conceptions. Furthermore, most of the value-trait links revealed with regression analysis, and the sinusoid relationships revealed with Pearson correlation coefficients were consistent with the findings measured with near universal instruments. Additionally found relationships between traits and especially conservation values can be interpreted as the instrumentality of agentic traits for personal as well for social focused values. Disposable income had a moderating effect on five trait-value relationships and three out of five were weaker in the low-income group.

    2004-07-01

    In this study, we aimed to construct, validate, and apply an instrument for assessing resident performance at outpatient preanesthesia consultation (PAC). A focus group and a Delphi panel of experts defined component items of a typical outpatient PAC, which could be used as indicators of competence. Items were incorporated in a checklist, which was further validated in a sample of consultations performed by board-certified anesthesiologists. The resulting instrument contained 37 items, grouped into five domains (physician-patient relationship, medical history, physical examination, patient education, and preanesthesia records), with high construct validity, high discriminant validity, moderate internal consistency, and high probability of inter-raters agreement. The instrument was applied to evaluate the performance of seven first-year residents at 317 consecutive PAC. Data were analyzed by constructing exponentially weighted moving average charts for domain and total scores. Statistically significant differing levels of performance could be consistently detected. Applying exponentially weighted moving average charts to the sequential analysis of the developed checklist scores can reliably assess resident performance at the devised criteria. The Preanesthesia Consultation Scoring Checklist is a potentially useful instrument for both formative and summative assessment of residents during their training in processes involved in outpatient preanesthesia evaluation.

    2007-02-01

    A new clinical diagnostic instrument for urea breath test (UBT) based non-invasive detection of Helicobacter Pylori is presented here. Its compact and low cost design makes it an economical and commercial alternative for the more expensive Isotope Ratio Mass Spectrometer (IRMS). The instrument is essentially a two channel non-dispersive IR spectrometer that performs high precision ratio measurements of the two carbon isotopomers ( 12CO II and 13CO II) present in exhaled breath. A balanced absorption system configuration was designed where the two channel path lengths would roughly be in the ratio of their concentrations. Equilibrium between the transmitted channel intensities was maintained by using a novel feedback servo mechanism to adjust the length of the 13C channel cell. Extensive computational simulations were performed to study the effect of various possible interferents and their results were considered in the design of the instrument so as to achieve the desired measurement precision of 1%. Specially designed gas cells and a custom made gas filling rig were also developed. A complete virtual interface for both instrument control and data acquisition was implemented in LABVIEW. Initial tests were used to validate the theory and a basic working device was demonstrated.

    2017-08-01

    Nurse educators might be unknowingly excluding learners secondary to teaching practices. Universal design for instruction (UDI) prepares and delivers accessible content and learning environments for diverse learners; however, it is not well known in nursing education. The aim of the study was to examine the psychometric properties of the Inclusive Teaching Strategies in Nursing Education (ITSinNE) 55-item instrument. Confirmatory factor analysis was performed on a sample of 311 educators in prelicensure programs. The ITSinNE scales had good to adequate estimates of reliability. The exogenous model fit the sample and model-implied covariance matrix; however, the endogenous model was not a good fit. Further instrument development is required. Measuring factors influencing nurse educators' willingness to adopt UDI will enable intervention research to enhance professional development fostering content and environmental access for all learners.

    Because of the increasing importance of heavy and unconventional crude oil as an energy source, there is a growing need for petroleomics: the pursuit of more complete and detailed knowledge of the chemical compositions of crude oil. Crude oil has an extremely complex nature; hence, techniques with ultra-high resolving capabilities, such as Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR MS), are necessary. FT-ICR MS has been successfully applied to the study of heavy and unconventional crude oils such as bitumen and shale oil. However, the analysis of crude oil with FT-ICR MS is not trivial, and it has pushed analysis to the limits of instrumental and methodological capabilities. For example, high-resolution mass spectra of crude oils may contain over 100,000 peaks that require interpretation. To visualize large data sets more effectively, data processing methods such as Kendrick mass defect analysis and statistical analyses have been developed. The successful application of FT-ICR MS to the study of crude oil has been critically dependent on key developments in FT-ICR MS instrumentation and data processing methods. This review offers an introduction to the basic principles, FT-ICR MS instrumentation development, ionization techniques, and data interpretation methods for petroleomics and is intended for readers having no prior experience in this field of study.

    A portable nondestructive measuring instrument for plant chlorophyll was developed, which can perform real-time, quick and nondestructive measurement of chlorophyll. The instrument is mainly composed of four parts, including leaves clamp, driving circuit of light source, photoelectric detection and signal conditioning circuit and micro-control system. A new scheme of light source driving was proposed, which can not only achieve constant current, but also control the current by digital signal. The driving current can be changed depending on different light source and measurement situation by actual operation, which resolves the matching problem of output intensity of light source and input range of photoelectric detector. In addition, an integrative leaves clamp was designed, which simplified the optical structure, enhanced the stability of apparatus, decreased the loss of incident light and improved the signal-to-noise ratio and precision. The photoelectric detection and signal conditioning circuit achieve the conversion between optical signal and electrical signal, and make the electrical signal meet the requirement of AD conversion, and the photo detector is S1133-14 of Hamamatsu Company, with a high detection precision. The micro-control system mainly achieves control function, dealing with data, data storage and so on. As the most important component, microprocessor MSP430F149 of TI Company has many advantages, such as high processing speed, low power, high stability and so on. And it has an in-built 12 bit AD converter, so the data-acquisition circuit is simpler. MSP430F149 is suitable for portable instrument. In the calibration experiment of the instrument, the standard value was measured by chlorophyll meter SPAD-502, multiple linear calibration models were built, and the instrument performance was evaluated. The correlation coefficient between chlorophyll prediction value and standard value is 0.97, and the root mean square error of prediction is about 1

    Full Text Available Introduction: Assessment environment, synonymous with climate or atmosphere, is multifaceted. Although there are valid and reliable instruments for measuring the educational environment, there is no validated instrument for measuring the assessment environment in medical programs. This study aimed to develop an instrument for measuring students’ perceptions of the assessment environment in an undergraduate medical program and to examine the psychometric properties of the new instrument. Method: The Assessment Environment Questionnaire (AEQ, a 40-item, four-point (1=Strongly Disagree to 4=Strongly Agree Likert scale instrument designed by the authors, was administered to medical undergraduates from the authors’ institution. The response rate was 626/794 (78.84%. To establish construct validity, exploratory factor analysis (EFA with principal component analysis and varimax rotation was conducted. To examine the internal consistency reliability of the instrument, Cronbach's α was computed. Mean scores for the entire AEQ and for each factor/subscale were calculated. Mean AEQ scores of students from different academic years and sex were examined. Results: Six hundred and eleven completed questionnaires were analysed. EFA extracted four factors: feedback mechanism (seven items, learning and performance (five items, information on assessment (five items, and assessment system/procedure (three items, which together explained 56.72% of the variance. Based on the four extracted factors/subscales, the AEQ was reduced to 20 items. Cronbach's α for the 20-item AEQ was 0.89, whereas Cronbach's α for the four factors/subscales ranged from 0.71 to 0.87. Mean score for the AEQ was 2.68/4.00. The factor/subscale of ‘feedback mechanism’ recorded the lowest mean (2.39/4.00, whereas the factor/subscale of ‘assessment system/procedure’ scored the highest mean (2.92/4.00. Significant differences were found among the AEQ scores of students from different

    Accelerator-produced electron beams are being studied for use in obtaining the response of beta-particle dosimetry instrumentation as a function of electron energy. The NBS 4 MV Van de Graaff and 500 kV cascaded rectifier accelerators are being used to generate electron beams from 200 keV to 2.5 MeV. A device capable of scanning the electron beam in two dimensions over an area large enough to cover radiation-survey instruments uniformly is attached to the beam-handling system of each accelerator. The scanned beam exits from vacuum through a 16 cm/sup 2/ window consisting of either 25 ..mu..m Kapton (for energies below 500 keV) or 100 ..mu..m aluminum. The electron beams produced have been characterized in terms of (1) spatial distribution, (2) energy spectrum, and (3) absorbed dose to plastic. Spatial distributions were determined using film, while spectra were measured using a 5 mm-deep Si surface barrier detector. An extrapolation chamber is being used for beam standardization in terms of absorbed dose to plastic. (orig.).

    Full Text Available Abstract Background The efficacy of natural products (NPs is being evaluated using randomized controlled trials (RCTs with increasing frequency, yet a search of the literature did not identify a widely accepted critical appraisal instrument developed specifically for use with NPs. The purpose of this project was to develop and evaluate a critical appraisal instrument that is sufficiently rigorous to be used in evaluating RCTs of conventional medicines, and also has a section specific for use with single entity NPs, including herbs and natural sourced chemicals. Methods Three phases of the project included: 1 using experts and a Delphi process to reach consensus on a list of items essential in describing the identity of an NP; 2 compiling a list of non-NP items important for evaluating the quality of an RCT using systematic review methodology to identify published instruments and then compiling item categories that were part of a validated instrument and/or had empirical evidence to support their inclusion and 3 conducting a field test to compare the new instrument to a published instrument for usefulness in evaluating the quality of 3 RCTs of a NP and in applying results to practice. Results Two Delphi rounds resulted in a list of 15 items essential in describing NPs. Seventeen item categories fitting inclusion criteria were identified from published instruments for conventional medicines. The new assessment instrument was assembled based on content of the two lists and the addition of a Reviewer's Conclusion section. The field test of the new instrument showed good criterion validity. Participants found it useful in translating evidence from RCTs to practice. Conclusion A new instrument for the critical appraisal of RCTs of NPs was developed and tested. The instrument is distinct from other available assessment instruments for RCTs of NPs in its systematic development and validation. The instrument is ready to be used by pharmacy students

    2012-01-01

    Full Text Available A plethora of surveys for assessing computer use for usability or technology acceptance exist today. This article discusses the Systems Acceptance Indicator, a validated survey instrument for assessing the user experience from a cognitive–ergonomic perspective. The action research discussed in this paper utilized grounded theory analysis to establish the data-driven emergent theoretical constructs that provided the system acceptance categories (criteria for the survey. These data-driven emergent theoretical constructs were the basis for the proposed theoretical abstraction hierarchy of the survey criteria. Principle component analysis of the survey data produced an abstraction hierarchy identical to the theoretical model. This result confirmed the alignment of the human–computer interaction theoretical constructs with the data-driven emergent theory. The intent behind the human–computer interaction theoretical rationale for the emergent abstraction hierarchy was to provide a consistent and repeatable interpretation of the user response to the survey.

    2016-08-01

    Self-neglect (SN) is a global phenomenon, largely hidden, poorly defined, and a serious public health issue. It can be intentional or unintentional and depends on the individual's capacity. Creating a safe living environment for self-neglecting adults can present complex ethical challenges. The purpose of this research was to develop and evaluate the psychometric properties of an instrument to measure professional's perceptions of self-neglect. A descriptive cross-sectional design was used in this two-stage study. Stage 1 involved the generation of an item pool (90 items), face and content validity; and pilot testing of the instrument. In stage 2, the questionnaire was posted to a national sample of community health and social care professionals (n=566) across Ireland, with a 60% response (n=339). Exploratory factor analysis (EFA) was conducted using scale development guidelines to identify scales and subscales of the instrument. Construct validity was established using EFA. The result was a 37-item SN instrument, composed of five factors: environment, social networks, emotional and behavioural liability, health avoidance, and self-determinism which explained 55.6% of the total variance. Factor loadings were ≥0.40 for all items on each of the five subscales. Cronbach's alpha (α) for four subscales ranged from 0.83 to 0.89 and one subscale was 0.69. The SN-37 can be used not only to measure SN, but also to develop interventions in practice. Further testing of the SN-37 in primary care settings with diverse populations is recommended.

    2015-06-01

    Full Text Available The development level assessment and categorization of Croatian local and regional units is based on the value of the development index which is the main instrument of Croatian regional policy. The development index is a composite indicator calculated as a weighted average of five socio-economic indicators. The goal of this paper is to analyze the uncertainty and sensitivity of the development index that arise from the procedures and indicators used in its construction. This analysis is then used to propose useful guidelines for future impovements. The methodology of the Croatian regional development index has been critically reviewed, revealing problems of multicollinearity and the existence of outliers. An empirical and relatively more objective multivariate approach for weight selection has been proposed. The uncertainty and sensitivity analysis were conducted using Monte Carlo simulations and variance-based techniques. Instead of a unique point estimate for the development level of territorial units an alternative confidence interval approach was considered.

    Full Text Available Establishing the validity of health behavior surveys used in community-based participatory research (CBPR in diverse populations is often overlooked. A novel, group-based cognitive interviewing method was used to obtain qualitative data for tailoring a survey instrument designed to identify barriers to improved cardiovascular health in at-risk populations in Washington, DC. A focus group–based cognitive interview was conducted to assess item comprehension, recall, and interpretation and to establish the initial content validity of the survey. Thematic analysis of verbatim transcripts yielded 5 main themes for which participants (n = 8 suggested survey modifications, including survey item improvements, suggestions for additional items, community-specific issues, changes in the skip logic of the survey items, and the identification of typographical errors. Population-specific modifications were made, including the development of more culturally appropriate questions relevant to the community. Group-based cognitive interviewing provided an efficient and effective method for piloting a cardiovascular health survey instrument using CBPR.

    Hypertension is a lifelong condition; thus, long-term adherence to lifestyle modification, self-monitoring, and medication regimens remains a challenge for patients. The aim of this study was to develop a patient-reported hypertension instrument that measured attitudes, lifestyle behaviors, adherence, and barriers to hypertension management using patient-reported outcome data. The study was conducted using the Open Research Exchange software platform created by PatientsLikeMe. A total of 360 participants completed the psychometric phase of the study; incomplete responses were obtained from 147 patients, and 150 patients opted out. Principal component analysis with orthogonal (varimax) rotation was executed on a data set with all completed responses (N = 249) and applied to 43 items. Based on the review of the factor solution, eigenvalues, and item loadings, 16 items were eliminated and model with 29 items was tested. The process was repeated two more times until final model with 14 items was established. In interpreting the rotated factor pattern, an item was said to load on any given component if the factor loading was ≥0.40 for that component and was <0.40 for the other. In addition to the newly generated instrument, demographic and self-reported clinical characteristics of the study participants such as the type of prescribed hypertension medications, frequency of blood pressure monitoring, and comorbid conditions were examined. The Open Research Exchange platform allowed for ongoing input from patients through each stage of the 14-item instrument development.

    Self-management has been associated with positive health outcomes among adults with chronic kidney disease (CKD). Perceived disease-related self-efficacy (DSE) is considered a critical component in the successful self-management of chronic disease. A valid and reliable instrument for measuring CKD patients' self-efficacy is needed. This study aims to develop and test a new instrument to measure the DSE of patients with early stage CKD. A total of 594 Taiwanese patients with early stage CKD recruited from two medical centers and one regional hospital in southern Taiwan completed the questionnaire. The CKD self-efficacy (CKD-SE) was evaluated using exploratory factor analyses (EFA) and measures of reliability. EFA identified four distinct factors with loadings ranging from 0.557 to 0.970: autonomy, self-integration, problem solving and seeking social support, accounting for 64.348% of the total variance. Cronbach's alpha coefficients for the subscales ranged from 0.843 to 0.901. This promising 25-item CKD-SE instrument can be used for the early identification of patients with low DSE, thus allowing the development of interventions to help these patients attain an appropriate level of DSE.

    Since 1999, our group at the CADIFT, University of Toronto, has developed the application of Frequency Domain Photothermal Radiometry (PTR) and Luminescence (LUM) to dental caries detection. Various cases including artificial caries detection have been studied and some of the inherent advantages of the adaptation of this technique to dental diagnostics in conjunction with modulated luminescence as a dual-probe technique have been reported. Based on these studies, a portable, compact diagnostic instrument for dental clinic use has been designed, assembled and tested. A semiconductor laser, optical fibers, a thermoelectric cooled mid-IR detector, and a USB connected data acquisition card were used. Software lock-in amplifier techniques were developed to compute amplitude and phase of PTR and LUM signals. In order to achieve fast measurement and acceptable signal-to-noise ratio (SNR) for clinical application, swept sine waveforms were used. As a result sampling and stabilization time for each measurement point was reduced to a few seconds. A sophisticated software interface was designed to simultaneously record intra-oral camera images with PTR and LUM responses. Preliminary results using this instrument during clinical trials in a dental clinic showed this instrument could detect early caries both from PTR and LUM signals.

    2014-06-01

    This article describes the development and field test of the Sound Concept Inventory Instrument (SCII), designed to measure middle school students' concepts of sound. The instrument was designed based on known students' difficulties in understanding sound and the history of science related to sound and focuses on two main aspects of sound: sound has material properties, and sound has process properties. The final SCII consists of 71 statements that respondents rate as either true or false and also indicate their confidence on a five-point scale. Administration to 355 middle school students resulted in a Cronbach alpha of 0.906, suggesting a high reliability. In addition, the average percentage of students' answers to statements that associate sound with material properties is significantly higher than the average percentage of statements associating sound with process properties (p <0.001). The SCII is a valid and reliable tool that can be used to determine students' conceptions of sound.

    The Integrated Robotics System Simulation (ROBSIM) was used to evaluate the performance of the PUMA 560 arm as applied to testing of inertial sensors. Results of this effort were used in the design and development of a feasibility test environment using a PUMA 560 arm. The implemented facility demonstrated the ability to perform conventional static inertial instrument tests (rotation and tumble). The facility included an efficient data acquisitions capability along with a precision test servomechanism function resulting in various data presentations which are included in the paper. Analysis of inertial instrument testing accuracy, repeatability and noise characteristics are provided for the PUMA 560 as well as for other possible commercial arm configurations. Another integral aspect of the effort was an in-depth economic analysis and comparison of robot arm testing versus use of contemporary precision test equipment.

    BNL is undertaking the design, construction and commissioning of the Spallation Neutron Source (SNS) accumulator ring and the beam transport lines [l]. Ultrahigh vacuum of 10{sup {minus}9} Torr is required in the accumulator ring to minimize beam-gas ionization, a contributing factor to the e-p instability observed in a few high-intensity proton storage rings. All vacuum instrumentation must be capable of local and remote operation to achieve a reliable vacuum system, especially in this extremely high intensity accelerator. The design and development of the SNS ring vacuum instrumentation and control through the Experimental Physics and Industrial Control System (EPICS) distributed real-time software tools are presented.

The system quantifies the optical efficiency of the lens by generating a performance map. The shape of the focused spot may also be analyzed to understand change in the lens performance. The primary instrument components (lasers and CCD detector) have been characterized to confirm their capability for performing optical transmittance measurements. Measurements performed on SoG and PMMA lenses subject to a variety of indoor conditions (e.g., UV and damp heat) identified differences in the optical efficiency of the evaluated lenses, demonstrating the ability of the Scanning Lens Instrument (SLI) to distinguish between the aged lenses.

    This article describes the development and validation of an instrument that can be used to assess students' perceptions of their learning environment as a means of monitoring and guiding changes toward social constructivist learning environments. The study used a mixed-method approach with priority given to the quantitative data collection. During the quantitative data collection phase, a new instrument—the Social Constructivist Learning Environment Survey (SCLES)—was developed and used to collect data from 1,955 grade 9 science students from 52 classes in 50 schools in the Western Cape province, South Africa. The data were analysed to evaluate the reliability and validity of the new instrument, which assessed six dimensions of the classroom learning environment, namely, Working with Ideas, Personal Relevance, Collaboration, Critical Voice, Uncertainty in Science and Respect for Difference. Two dimensions were developed specifically for the present study in order to contextualise the questionnaire to the requirements of the new South African curriculum (namely, Metacognition and Respect for Difference). In the qualitative data collection phase, two case studies were used to investigate whether profiles of class mean scores on the new instrument could provide an accurate and "trustworthy" description of the learning environment of individual science classes. The study makes significant contributions to the field of learning environments in that it is one of the first major studies of its kind in South Africa with a focus on social constructivism and because the instrument developed captures important aspects of the learning environment associated with social constructivism.

    To report the development and psychometric evaluation of a scale to measure rural and remote (rural/remote) nurses' perceptions of the engagement of their workplaces in key dimensions of primary health care (PHC). Amidst ongoing PHC reforms, a comprehensive instrument is needed to evaluate the degree to which rural/remote health care settings are involved in the key dimensions that characterize PHC delivery, particularly from the perspective of professionals delivering care. This study followed a three-phase process of instrument development and psychometric evaluation. A literature review and expert consultation informed instrument development in the first phase, followed by an iterative process of content evaluation in the second phase. In the final phase, a pilot survey was undertaken and item discrimination analysis employed to evaluate the internal consistency reliability of each subscale in the preliminary 60-item Primary Health Care Engagement (PHCE) Scale. The 60-item scale was subsequently refined to a 40-item instrument. The pilot survey sample included 89 nurses in current practice who had experience in rural/remote practice settings. Participants completed either a web-based or paper survey from September to December, 2013. Following item discrimination analysis, the 60-item instrument was refined to a 40-item PHCE Scale consisting of 10 subscales, each including three to five items. Alpha estimates of the 10 refined subscales ranged from 0.61 to 0.83, with seven of the subscales demonstrating acceptable reliability (α ⩾ 0.70). The refined 40-item instrument exhibited good internal consistency reliability (α=0.91). The 40-item PHCE Scale may be considered for use in future studies regardless of locale, to measure the extent to which health care professionals perceive their workplaces to be engaged in key dimensions of PHC.

    Full Text Available Patients with Parkinson disease are increasingly recognized to suffer from non-motor symptoms in addition to motor symptoms. Many non-motor symptoms fluctuate in parallel with motor symptoms and in relationship to plasma levodopa levels. Though these symptoms are troublesome and result in reduced quality of life to patients and their caregivers, there has not been an objective method of recognizing and quantifying non-motor fluctuations (NMFs. This study sought to develop a patient-based instrument that would accurately capture the experience of patients with NMFs. Patient-based nominal group technique sessions, focus groups, and expert opinion were utilized in developing this questionnaire.

    Full Text Available Introduction: one of the key aspects of the knowledge economy development is the growing significance of the results of research and development. The education and basic research play a key role in this process. Funding for education and fundamental science is carried out mainly at the expense of the state resources, including a system of foundations for scientific, engineering and innovation activities in Russia. The purpose of this article is to present recommendations for improving the tools of domestic foundations in funding fundamental research and development, including education and training. The propositions are made with a comparative analysis of the domestic and foreign science foun dations’ activities. Materials and Methods: the authors used analysis, comparison, induction, deduction, graphical analysis, generalisation and other scientific methods during the study. Results: the lack of comparability between domestic and foreign scientific funds in the volume of funding allocated for basic research and development is revealed. This situation affects the scientific research. The foreign foundations have a wide range of instruments to support research projects at all stages of the life cycle of grants for education and training prior to release of an innovative product to market (the use of “innovation elevator” system. The Russian national scientific foundations have no such possibilities. The authors guess that the Russian organisations ignore some of the instruments for supporting research and development. Use of these tools could enhance the effectiveness of research projects. According to the study of domestic and foreign experience in supporting research and development, the authors proposed a matrix composed of instruments for support in the fields of basic scientific researches and education with such phases of the project life cycle as “research” and “development”. Discussion and Conclusions: the foreign science

    Full Text Available Abstract Background In the era of cost containment, managers are constantly pursuing increased organizational performance and productivity by aiming at the obvious target, i.e. the workforce. The health care sector, in which production processes are more complicated compared to other industries, is not an exception. In light of recent legislation in Greece in which efficiency improvement and achievement of specific performance targets are identified as undisputable health system goals, the purpose of this study was to develop a reliable and valid instrument for investigating the attitudes of Greek physicians, nurses and administrative personnel towards job-related aspects, and the extent to which these motivate them to improve performance and increase productivity. Methods A methodological exploratory design was employed in three phases: a content development and assessment, which resulted in a 28-item instrument, b pilot testing (N = 74 and c field testing (N = 353. Internal consistency reliability was tested via Cronbach's alpha coefficient and factor analysis was used to identify the underlying constructs. Tests of scaling assumptions, according to the Multitrait-Multimethod Matrix, were used to confirm the hypothesized component structure. Results Four components, referring to intrinsic individual needs and external job-related aspects, were revealed and explain 59.61% of the variability. They were subsequently labeled: job attributes, remuneration, co-workers and achievement. Nine items not meeting item-scale criteria were removed, resulting in a 19-item instrument. Scale reliability ranged from 0.782 to 0.901 and internal item consistency and discriminant validity criteria were satisfied. Conclusion Overall, the instrument appears to be a promising tool for hospital administrations in their attempt to identify job-related factors, which motivate their employees. The psychometric properties were good and warrant administration to a larger

    It is necessary to develop various types of welding, instrumentation and helium gas filling techniques that can conduct TIG spot welding exactly at a pin-hole of the end-cap on the nuclear fuel rod to fill up helium gas. The welding process is one of the most important among the instrumentation processes of the nuclear fuel test rod. To manufacture the nuclear fuel test rod, a precision welding system needs to be fabricated to develop various welding technologies of the fuel test rod jointing the various sensors and end-caps on a fuel cladding tube, which is charged with fuel pellets and component parts. We therefore designed and fabricated an orbital TIG welding system and a laser welding system. This paper describes not only some experiment results from weld tests for the parts of a nuclear fuel test rod, but also the contents for the instrumentation process of the dummy fuel test rod installed with the C-type T. C. A dummy nuclear fuel test rod was successfully fabricated with the welding and instrumentation technologies acquired with various tests. In the test results, the round welding has shown a good weldability at both the orbital TIG welding system and the fiber laser welding system. The spot welding to fill up helium gas has shown a good welding performance at a welding current of 30A, welding time of 0.4 sec and gap of 1 mm in a helium gas atmosphere. The soundness of the nuclear fuel test rod sealed by a mechanical sealing method was confirmed by helium leak tests and microstructural analyses.

    Nasimi, Elnara

    Due to the age and operating experience of Bruce Power units, equipment ageing and obsolescence has become one of the main challenges that need to be resolved for all systems, structures and components in order to ensure a safe and reliable production of energy. The research objectives of this thesis will focus on methodology for modernization of Start-Up Instrumentation (SUI), both in-core and Control Room equipment, using a new generation of detectors and cables in order to manage obsolescence. The main objective of this thesis is to develop a new systematic approach to SUI installation/replacement procedure development and optimization. Although some additional features, such as real-time data monitoring and storage/archiving solutions for SUI systems are also examined to take full advantage of today's digital technology, the objective of this thesis does not include detailed parametrical studies of detector or system performance. Instead, a number of technological, operational and maintenance issues associated with Start-Up Instrumentation systems at Bruce Power will be identified in this project and a structured approach to developing a replacement/installation procedure that can be standardized and used across all of the domestic CANDU stations is proposed. Finally, benefits of Hierarchical Control Chart (HCC) methodology for all stages of plant life management, such as system design, development, operation and maintenance are demonstrated. Keywords: Task Breakdown and Analysis methodology, installation/removal procedure development and optimization, risk-based analysis and optimization, Hierarchical Control Chart (HCC) methodology for system maintenance and troubleshooting, Start-Up Instrumentation (SUI), Ion Chambers, Fission Chambers, proportional counters, Shutdown System 1 (SDS1), Shutdown System 2 (SDS2).

    Background:The nature of technology has been rarely discussed despite the fact that technology plays an essential role in modern society. It is important to discuss students' concepts of the nature of technology, and further to advance their technological literacy and adaptation to modern society. There is a need to assess high school students' concepts of the nature of technology. Purpose:This study aims to engage in discourse on students' concepts of the nature of technology based on a proposed theoretical framework. Moreover, another goal is to develop an instrument for measuring students' concepts of the nature of technology. Sample:Four hundred and fifty-five high school students' perceptions of technology were qualitatively analyzed. Furthermore, 530 students' responses to a newly developed questionnaire were quantitatively analyzed in the final test. Design and method:First, content analysis was utilized to discuss and categorize students' statements regarding technology and its related issues. The Student Concepts of the Nature of Technology Questionnaire was developed based on the proposed theoretical framework and was supported by the students' qualitative data. Finally, exploratory factor analysis and reliability analysis were applied to determine the structure of the items and the internal consistency of each scale. Results:Through a process of instrument development, the Student Concepts of the Nature of Technology Questionnaire was shown to be a valid and reliable tool for measuring students' concepts of the nature of technology. This newly developed questionnaire is composed of 29 items in six scales, namely 'technology as artifacts,' 'technology as an innovation change,' 'the current role of technology in society,' 'technology as a double-edged sword,' 'technology as a science-based form,' and 'history of technology.' Conclusions:The Student Concepts of the Nature of Technology Questionnaire has been confirmed as a reasonably valid and reliable

    Participation of healthcare professionals in information technology development has emerged as an important challenge. As end-users, the professionals are willing to participate in the development activities, but their experiences on the current methods of participation remain mostly negative. There is lack of applicable methods for meeting the needs of agile development approach and scaling up to the largest implementation projects, while maintaining the interest of the professional users to participate in development activities and keeping up their ability to continue working in a productive manner. In this paper, we describe the Agile Instrumented Monitoring as a methodology, based on the methods of instrumented usability evaluation, for improving user experience in HealthIT development. The contribution of the proposed methodology is analyzed in relation to activities of whole iteration cycle and chosen usability evaluation methods, while the user experience of participation is addressed regarding healthcare professionals. Prospective weak and strong market tests for AIM are discussed in the conclusions for future work.

    The participation of IRS in entry missions is two-fold: development activities e.g. in the field of TPS qualification using the IRS plasma wind tunnels are successfully performed such as for Titan Huygens or PARES. Another field is the development of in-flight instrumentations and measurement techniques for observation missions. On this basis such systems have been developed and/or flown aboard vehicles such as EXPRESS, MIRKA, IRDT and X38. In 2006 IRS participated in the airborne observation mission for STARDUST using a spectroscopic set-up developed specifically for this purpose on basis of a laboratory spectrometer. Presently, three different in-flight measurement systems are being developed at IRS for the aerothermodynamic demonstrator capsule EXPERT. A further combined system called COMPARE is in the design phase for SHEFEX2. In addition, the data of the observation mission for the entry of ATV the end of September 2008 is being evaluated.

  12. Development of a Binary Mixture Gas Composition Instrument for Use in a Confined High Temperature Environment

    Cadell, Seth R.

    With recent advancements in material science, industrial operations are being conducted at higher and higher temperatures. This is apparent in the nuclear industry where a division of the field is working to develop the High Temperature Gas Reactor and the Very High Temperature Gas Reactor concurrently. Both of these facilities will have outlet gas temperatures that are at significantly higher temperatures than the typical water cooled reactor. These increased temperatures provide improved efficiency for the production of hydrogen, provide direct heating for oil refineries, or more efficient electricity generation. As high temperature operations are being developed, instruments capable of measuring the operating parameters must be developed concurrently. Within the gas reactor community there is a need to measure the impurities within the primary coolant. Current devices will not survive the temperature and radiation environments of a nuclear reactor. An instrument is needed to measure the impurities within the coolant while living inside the reactor, where this instrument would measure the amount of the impurity within the coolant. There are many industrial applications that need to measure the ratio of two components, whether it be the amount of particulate in air that is typical to pneumatic pumping, or the liquid to gas ratio in natural gas as it flows through a pipeline. All of the measurements in these applications can be met using a capacitance sensor. Current capacitance sensors are built to operate at ambient temperatures with only one company producing a product that will handle a temperature of up to 400 °C. This maximum operating temperature is much too low to measure the gas characteristics in the High Temperature Gas Reactor. If this measurement technique were to be improved to operate at the expected temperatures, the coolant within the primary loop could be monitored for water leaks in the steam generator, carbon dust buildup entrained in the flow

    Full Text Available The Open Geospatial Consortium (OGC is committed to developing quality open standards for the global geospatial community, thus enhancing the interoperability of geographic information. In the domain of sensor networks, the Sensor Web Enablement (SWE initiative has been developed to define the necessary context by introducing modeling standards, like ‘Observation & Measurement’ (O&M and services to provide interaction like ‘Sensor Observation Service’ (SOS. Land surveying measurements on the other hand comprise a domain where observation information structures and services have not been aligned to the OGC observation model. In this paper, an OGC-compatible, aligned to the ‘Observation and Measurements’ standard, model for land surveying observations has been developed and discussed. Furthermore, a case study instantiates the above model, and an SOS implementation has been developed based on the 52° North SOS platform. Finally, a visualization schema is used to produce ‘Web Map Service (WMS’ observation maps. Even though there are elements that differentiate this work from classic ‘O&M’ modeling cases, the proposed model and flows are developed in order to provide the benefits of standardizing land surveying measurement data (cost reducing by reusability, higher precision level, data fusion of multiple sources, raw observation spatiotemporal repository access, development of Measurement-Based GIS (MBGIS to the geoinformation community.

    The International Atomic Energy Agency recommends the use of safety and friendly interfaces for monitoring and controlling the operational parameters of the nuclear reactors. This article describes a digital system being developed to simulate the behavior of the operating parameters using virtual instruments. The control objective is to bring the reactor power from its source level (mW) to a full power (kW). It is intended for education of basic reactor neutronic and thermohydraulic principles such as the multiplication factor, criticality, reactivity, period, delayed neutron, control by rods, fuel and coolant temperatures, power, etc. The 250 kW IPR-R1 TRIGA research reactor at Nuclear Technology Development Centre - CDTN was used as reference. TRIGA reactors, developed by General Atomics (GA), are the most widely used research reactor in the world. The simulator system is being developed using the LabVIEW (Laboratory Virtual Instruments Engineering Workbench) software, considering the modern concept of virtual instruments (VI's) using electronic processor and visual interface in video monitor. The main purpose of the system is to provide training tools for instructors and students, allowing navigating by user-friendly operator interface and monitoring tendencies of the operational variables. It will be an interactive tool for training and teaching and could be used to predict the reactor behavior. Some scenarios are presented to demonstrate that it is possible to know the behavior of some variables from knowledge of input parameters. The TRIGA simulator system will allow the study of parameters, which affect the reactor operation, without the necessity of using the facility. (author)

    It is often believed that energy policy and policy instruments can play a significant role in the transition towards sustainable energy by stimulating and accelerating the development and deployment of new energy technologies. However, despite the known need for, and benefits of, new energy technologies their market introduction and expansion is often slow. Wind power has been on the political agenda since the 1970s in several European countries as well as in other countries throughout the world. However, the technology and market development of wind power has been very different in these countries. Despite three decades of policy intervention the installed capacity in Sweden was only 265 MW in 2000, compared with 6,107 MW in Germany, 2,836 MW in Spain and 2,341 MW in Denmark. This report analyses the effects of policy instruments on wind power development in Sweden and identifies possible reasons why wind power has not been installed to a greater extent. The analysis is based on an empirical example of a socio technological system-based approach to evaluation of technology and market development for new energy technologies; i.e. an approach focused on the technological system including the actors, institutions and organizations that build, drive and utilise it and the economic and legal framework that regulates it. The aim is to assess the impact on technology and market development and to discuss the relatively late and slow wind power development in Sweden. The report also examines the achievement of governmental energy policy goals. Using the socio-technological systems approach we analyse Swedish policy programmes and wind power development between 1975 and 2000. The political and economic framework is identified. The discussion of the political and economic frameworks is limited to public policy goals and policy instruments. The policy focus is set to policy instruments aimed for technology and market development of wind power, such as research and

    Research to document the effects of nursing on patient outcomes such as pain has been limited by the inability to measure the quality of nursing care effectively. The purpose of this study was to establish content validity and to evaluate patient understanding of Pain Care Quality (PainCQ) survey items using cognitive interviewing. In the development phase, 101 items representing four constructs were generated from the transcriptions of 33 qualitative interviews conducted with cancer patients in pain. In the judgment phase, items were reviewed systematically by two panels of pain experts. In the final phase, cognitive interviews were conducted with hospitalized cancer patients reporting pain. Content validity was established if eight of nine (p item was relevant or very relevant. On the basis of the expert panel review, items were deleted, reworded, and added, and 73 items remained. These items were evaluated by cognitive interviews with 39 hospitalized patients with multiple types of cancer in three states. The mean age was 58.87 years, and 60.5% were women. Most were non-Hispanic White (94.7%), and education varied. On a 0 to 10 scale, worst pain during the past shift averaged 5.24 (SD = 2.43). Participant responses to the PainCQ survey items were summarized for each item using a matrix tool and evaluated in team meetings. Through an iterative process, items were revised and reduced to produce the PainCQ survey (v3) with 44 items. Through this deliberative and iterative process, an instrument was produced that will contribute to the measurement of the quality of nursing and interdisciplinary care related to pain management. The items retained in the PainCQ were understood and judged by hospitalized patients with pain easily. Further psychometric testing of the PainCQ is indicated.

    This study proposes an electrochemical micromachining instrument for two confined etching techniques, namely, confined etchant layer technique (CELT) and electrochemical wet stamping (E-WETS). The proposed instrument consists of a granite bridge base, a Z-axis coarse/fine dual stage, and a force sensor. The Z-axis coarse/fine dual stage controls the vertical movement of the substrate with nanometer accuracy. The force sensor measures the contact force between the mold and the substrate. A contact detection method based on a digital lock-in amplifier is developed to make the mold-substrate contact within a five-nanometer range in CELT, and a force feedback controller is implemented to keep the contact force in E-WETS at a constant value with a noise of less than 0.2 mN. With the use of the confined etching techniques, a microlens array and a curvilinear ridge microstructure are successfully fabricated with high accuracy, thus demonstrating the promising performance of the proposed micromachining instrument.

    Full Text Available The following paper introduces a new approach to the analysis of offensive game in football. Therefore, the main aim of this study was to create an instrument for collecting information for the analysis of offensive action and interactions game. The observation instrument that was used to accomplish the main objective of this work consists of a combination of format fields (FC and systems of categories (SC. This methodology is a particular strategy of the scientific method that has as an objective to analyse the perceptible behaviour that occurs in habitual contexts, allowing them to be formally recorded and quantified and using an ad hoc instrument in order to obtain a behaviour systematic registration that, since they have been transformed in quantitative data with the necessary reliability and validity determined level, will allow analysis of the relations between these behaviours. The codifications undertaken to date in various games of football have shown that it serves the purposes for which it was developed, allowing more research into the offensive game methods in football.

    In April 2003, South Texas Project Unit 1 made a surprising discovery of boron acid leakage from two nozzles from a bare-metal examination of the reactor vessel bottom-mounted instrument penetrations during a routine refueling outage. A small powdery substance about 150mg was found on the outside of two instrument guide penetration nozzles on the bottom of the reactor. The primary coolant water of pressurized water reactors has caused cracking in penetrations with Alloy 600 through a process called primary water stress corrosion cracking. In South Korea, it is scheduled to conduct visual inspection of the outside of instrument guide penetration nozzles on the bottom of PWRs to confirm the integrity of reactor vessel. Inside the bottom head of KSNP, 45 penetration nozzles with the radius of about 7.5cm are mounted. The height of the nozzle located on the center is about 6 and the minimum distance between the nozzles is about 20 cm. In order to inspect the possible leakage of boron acid, two mobile robots are developed and described in this paper.
