    Background. The Psychology Experiment Building Language (PEBL) software consists of over one-hundred computerized tests based on classic and novel cognitive neuropsychology and behavioral neurology measures. Although the PEBL tests are becoming more widely utilized, there is currently very limited information about the psychometric properties of these measures. Methods. Study I examined inter-relationships among nine PEBL tests including indices of motor-function (Pursuit Rotor and Dexterity), attention (Test of Attentional Vigilance and Time-Wall), working memory (Digit Span Forward), and executive-function (PEBL Trail Making Test, Berg/Wisconsin Card Sorting Test, Iowa Gambling Test, and Mental Rotation) in a normative sample (N = 189, ages 18–22). Study II evaluated test–retest reliability with a two-week interest interval between administrations in a separate sample (N = 79, ages 18–22). Results. Moderate intra-test, but low inter-test, correlations were observed and ceiling/floor effects were uncommon. Sex differences were identified on the Pursuit Rotor (Cohen’s d = 0.89) and Mental Rotation (d = 0.31) tests. The correlation between the test and retest was high for tests of motor learning (Pursuit Rotor time on target r = .86) and attention (Test of Attentional Vigilance response time r = .79), intermediate for memory (digit span r = .63) but lower for the executive function indices (Wisconsin/Berg Card Sorting Test perseverative errors = .45, Tower of London moves = .15). Significant practice effects were identified on several indices of executive function. Conclusions. These results are broadly supportive of the reliability and validity of individual PEBL tests in this sample. These findings indicate that the freely downloadable, open-source PEBL battery (http://pebl.sourceforge.net) is a versatile research tool to study individual differences in neurocognitive performance.

    We present selected results from a series of Open Stack thermal battery tests performed in FY14 and FY15 and discuss our findings. These tests were meant to provide validation data for the comprehensive thermal battery simulation tools currently under development in Sierra/Aria under known conditions compared with as-manufactured batteries. We are able to satisfy this original objective in the present study for some test conditions. Measurements from each test include: nominal stack pressure (axial stress) vs. time in the cold state and during battery ignition, battery voltage vs. time against a prescribed current draw with periodic pulses, and images transverse to the battery axis from which cell displacements are computed. Six battery configurations were evaluated: 3, 5, and 10 cell stacks sandwiched between 4 layers of the materials used for axial thermal insulation, either Fiberfrax Board or MinK. In addition to the results from 3, 5, and 10 cell stacks with either in-line Fiberfrax Board or MinK insulation, a series of cell-free “control” tests were performed that show the inherent settling and stress relaxation based on the interaction between the insulation and heat pellets alone.

    In early January 1981, Sandia National Laboratories began testing sealed lead-acid batteries which were being developed under Sandia contracts. The goal was to develop a totally maintenance-free sealed lead-acid battery capable of deep-discharge operation in a photovoltaic power system. Sealed lead-acid batteries and a group of conventional, flooded lead-acid batteries were exposed to a matrix test plan, with some approaching 1000 cycles. This performance was achieved with the standard National Electrical Manufacturers' Association cycle test, as well as the partial-state-of-charge cycle test. Modes of failure are being investigated.

    The test battery was developed to provide a standard procedure for cursor control device evaluation. The software was built in Visual Basic and consists of nine tasks and a main menu that integrates the set-up of the tasks. The tasks can be used individually, or in a series defined in the main menu. Task 1, the Unidirectional Pointing Task, tests the speed and accuracy of clicking on targets. Two rectangles with an adjustable width and adjustable center- to-center distance are presented. The task is to click back and forth between the two rectangles. Clicks outside of the rectangles are recorded as errors. Task 2, Multidirectional Pointing Task, measures speed and accuracy of clicking on targets approached from different angles. Twenty-five numbered squares of adjustable width are arranged around an adjustable diameter circle. The task is to point and click on the numbered squares (placed on opposite sides of the circle) in consecutive order. Clicks outside of the squares are recorded as errors. Task 3, Unidirectional (horizontal) Dragging Task, is similar to dragging a file into a folder on a computer desktop. Task 3 requires dragging a square of adjustable width from one rectangle and dropping it into another. The width of each rectangle is adjustable, as well as the distance between the two rectangles. Dropping the square outside of the rectangles is recorded as an error. Task 4, Unidirectional Path Following, is similar to Task 3. The task is to drag a square through a tunnel consisting of two lines. The size of the square and the width of the tunnel are adjustable. If the square touches any of the lines, it is counted as an error and the task is restarted. Task 5, Text Selection, involves clicking on a Start button, and then moving directly to the underlined portion of the displayed text and highlighting it. The pointing distance to the text is adjustable, as well as the to-be-selected font size and the underlined character length. If the selection does not

    In support of the Partnership for a New Generation of Vehicles (PNGV), the Idaho National Engineering and Environmental Laboratory (INEEL) has developed novel testing procedures and analytical methodologies to assess the performance of batteries for use in hybrid electric vehicles (HEV’s). Tests have been designed for both Power Assist and Dual Mode applications. They include both characterization and cycle life and/or calendar life. At periodic intervals during life testing, a series of Reference Performance Tests are executed to determine changes in the baseline performance of the batteries. Analytical procedures include a battery scaling methodology, the calculation of pulse resistance, pulse power, available energy, and differential capacity, and the modeling of calendar- and cycle-life data. PNGV goals, test procedures, analytical methodologies, and representative results are presented.

    The use of adequate assessment tools in health care is crucial for the management of care. The lack of specific tools in Portugal for assessing the performance of children who use cochlear implants motivated the translation and adaptation of the EARS (Evaluation of Auditory Responses to Speech) test battery into European Portuguese. This test battery is today one of the most commonly used by (re)habilitation teams of deaf children who use cochlear implants worldwide. The goal to be achieved with the validation of EARS was to provide (re)habilitation teams an instrument that enables: (i) monitoring the progress of individual (re)habilitation, (ii) managing a (re)habilitation program according to objective results, comparable between different (re)habilitation teams, (iii) obtaining data that can be compared with the results of international teams, and (iv) improving engagement and motivation of the family and other professionals from local teams. For the test battery translation and adaptation process, the adopted procedures were the following: (i) translation of the English version into European Portuguese by a professional translator, (ii) revision of the translation performed by an expert panel, including doctors, speech-language pathologists and audiologists, (iii) adaptation of the test stimuli by the team's speechlanguage pathologist, and (iv) further review by the expert panel. For each of the tests that belong to the EARS battery, the introduced adaptations and adjustments are presented, combining the characteristics and objectives of the original tests with the linguistic and cultural specificities of the Portuguese population. The difficulties that have been encountered during the translation and adaptation process and the adopted solutions are discussed. Comparisons are made with other versions of the EARS battery. We defend that the translation and the adaptation process followed for the EARS test battery into European Portuguese was correctly conducted

  15. Factor structure of intelligence test battery KOG9

    Lazarević Ljiljana B.

    2008-01-01

    Full Text Available Authors of Cybernetic model of cognitive functioning designed a battery of tests (KOG9, based on the model in order to assess cognitive efficiency. Authors assert that scale's factor structure comprises the three factors: perceptive, serial and parallel processing. Results of the previous research as well as the logical analysis of the origin and content of the tests suggested the possibility that more parsimonious two-factor solution can explain the structure of the correlations among them equally well. KOG9 battery was administered to 1116 students of Faculty of sport and physical education and students from Department of Psychology in order to study its latent structure. In spite of the fact that factor congruence analyses suggested higher robustness (cross-sample stability of the two-factor solution, results of both EFA and CFA spoke in favor of the three-factor solution. The problem of the lack of stability of the three-factor solution was located in not particularly well targeted choice of the markers of the efficacy of perceptual processing. The suggestion is to preserve the calculation of all three group scores, with some corrections. First of all, tests CF2 and/or GT7 should be replaced by some other perceptual test/tests of lower cognitive complexity. Some of the tests tapping parallel processing should be replaced by those more in line with the logic of the model.

    2013-10-01

    Several large electric vehicle batteries available to the National Highway Traffic Safety Administration are candidates for use in future safety testing programs. The batteries, from vehicles subjected to NCAP crashworthiness testing, are considered potentially damaged due to the nature of testing their associated vehicles have been subjected to. Criteria for safe shipping to Sandia is discussed, as well as condition the batteries must be in to perform testing work. Also discussed are potential tests that could be performed under a variety of conditions. The ultimate value of potential testing performed on these cells will rest on the level of access available to the battery pack, i.e. external access only, access to the on board monitoring system/CAN port or internal electrical access to the battery. Greater access to the battery than external visual and temperature monitoring would likely require input from the battery manufacturer.

    In early January 1981, Sandia began testing sealed lead-acid batteries which were being developed under Sandia contracts. Goal was to develop a totally maintenance-free sealed lead-acid battery capable of deep-discharge operation in a photovoltaic power system. During contracts with Gould and Eagle-Picher, batteries were received quarterly and placed on test. Testing of these batteries has now been completed. With proper charging, battery life averaged over 800 deep cycles. This was achieved with both the standard NEMA cycle test as well as a partial state of charge test. Charging voltages above 2.50 volts per cell appeared to be detrimental to the performance of the Gould batteries.

    Testing was conducted to measure electrical performance and safety of the General Electric Durathon™ E620 battery module (600 V class 20 kWh) during cell overcharge. Data gathered from this test was consistent with SAE Electric Vehicle Battery Abuse Testing specification J2464 [1]. After cell overcharge failure and 24 A current flow for additional 60 minutes, battery was then discharged at 7.5 KW average power to 12% state of charge (SOC) and recharged back to 100% SOC. This overcharging test was performed on two cells. No hydrogen chloride (HCl) gas was detected during front cell (B1) test, and small amount (6.2 ppm peak) was measured outside the battery after center cell (F13) overcharge. An additional overcharge test was performed per UL Standard 1973 - Batteries for Use in Light Electric Rail (LER) Applications and Stationary Applications[2]. With the battery at 11% SOC and 280 °C float temperature, an individual cell near the front (D1) was deliberately imbalanced by charging it to 62% SOC. The battery was then recharged to 100% SOC. In all three tests, the battery cell pack was stable and individual cell failure did not propagate to other cells. Battery discharge performance, charge performance, and electrical isolation were normal after all three tests.

    This report presents the results of a seismic testing program on naturally aged class 1E batteries obtained from a nuclear plant. The testing program is a Phase 2 activity resulting from a Phase 1 aging evaluation of class 1E batteries in safety systems of nuclear power plants, performed previously as a part of the US Nuclear Regulatory Commission's Nuclear Plant Aging Research Program and reported in NUREG/CR-4457. The primary purpose of the program was to evaluate the seismic ruggedness of naturally aged batteries to determine if aged batteries could have adequate electrical capacity, as determined by tests recommended by IEEE Standards, and yet have inadequate seismic ruggedness to provide needed electrical power during and after a safe shutdown earthquake (SSE) event. A secondary purpose of the program was to evaluate selected advanced surveillance methods to determine if they were likely to be more sensitive to the aging degradation that reduces seismic ruggedness. The program used twelve batteries naturally aged to about 14 years of age in a nuclear facility and tested them at four different seismic levels representative of the levels of possible earthquakes specified for nuclear plants in the United States. Seismic testing of the batteries did not cause any loss of electrical capacity. 19 refs., 29 figs., 7 tabs.

    a battery of tests covering a larger range of auditory capabilities in order to assess individual listeners. The format of all tests is kept as 'objective' as possible by using a three-alternative forced-choice paradigm in which the subject must choose which of the sound samples is different, thus keeping...... the instruction to the subjects simple and common for all tests. Both basic (e.g. frequency discrimination) and complex (e.g. profile analysis) psychoacoustic tests are covered in the battery and a threshold of discrimination or detection is obtained for each test. Data were collected on 24 listeners who had been...... recruited for participation in an expert listening panel for evaluating the sound quality of hi-fi audio systems. The test battery data were related to the actual performance of the listeners when judging the degradation in quality produced by audio codecs....

    Synesthesia is a neurological condition that gives rise to unusual secondary sensations (e.g., reading letters might trigger the experience of colour). Testing the consistency of these sensations over long time intervals is the behavioural gold standard assessment for detecting synesthesia (e.g., Simner, Mulvenna et al., 2006). In 2007 however, Eagleman and colleagues presented an online 'Synesthesia Battery' of tests aimed at identifying synesthesia by assessing consistency but within a single test session. This battery has been widely used but has never been previously validated against conventional long-term retesting, and with a randomly recruited sample from the general population. We recruited 2847 participants to complete The Synesthesia Battery and found the prevalence of grapheme-colour synesthesia in the general population to be 1.2%. This prevalence was in line with previous conventional prevalence estimates based on conventional long-term testing (e.g., Simner, Mulvenna et al., 2006). This reproduction of similar prevalence rates suggests that the Synesthesia Battery is indeed a valid methodology for assessing synesthesia. Copyright © 2015 The Authors. Published by Elsevier Inc.

    This battery test procedure manual was prepared for the United States Department of Energy (DOE), Office of Energy Efficiency and Renewable Energy (EERE), Vehicle Technologies Office. It is based on technical targets for commercial viability established for energy storage development projects aimed at meeting system level DOE goals for Electric Vehicles (EV). The specific procedures defined in this manual support the performance and life characterization of advanced battery devices under development for EVs. However, it does share some methods described in the previously published battery test manual for plug-in hybrid electric vehicles. Due to the complexity of some of the procedures and supporting analysis, future revisions including some modifications and clarifications of these procedures are expected. As in previous battery and capacitor test manuals, this version of the manual defines testing methods for full-size battery systems, along with provisions for scaling these tests for modules, cells or other subscale level devices. The DOE-United States Advanced Battery Consortium (USABC), Technical Advisory Committee (TAC) supported the development of the manual. Technical Team points of contact responsible for its development and revision are Chul Bae of Ford Motor Company and Jon P. Christophersen of the Idaho National Laboratory. The development of this manual was funded by the Unites States Department of Energy, Office of Energy Efficiency and Renewable Energy, Vehicle Technologies Office. Technical direction from DOE was provided by David Howell, Energy Storage R&D Manager and Hybrid Electric Systems Team Leader. Comments and questions regarding the manual should be directed to Jon P.

    Sodium-sulfur batteries have been developed to provide load-leveling and stabilize the supply of electricity for electric utilities and large customers. However, concern for safety increases with the amount of sodium and sulfur required for commercial products. The latest (and largest) product is a 50 kW, 400 kWh battery module comprised of 384 cells, designated 'T5' cells. Safety is ensured by applying multiple levels of protection during design and manufacture, and confirmed by rigorous safety tests to verify performance during accident conditions that cause electrical, mechanical, thermal and chemical hazards. These tests have proven that the T5 cell and 50 kW battery module are adequately safe during such events for use in commercial applications. (orig.)

The objective of this study was to adapt and test the AAHPERD in institutionalized older adults and to define normative values of functional fitness for this population. A pilot test was conducted on older adults living in nursing homes, which confirmed the need to adapt the flexibility and aerobic endurance tests. The first test was redesigned so that the elderly person did not have to sit on the floor. The second test was changed from a half-mile to a 6-minute walk. The tests were adapted and tested in a sample of 92 older adults from six long-term care homes. The successful application of the AAHPERD adapted for older adults living in nursing homes permitted the establishment of normative values for the five motor tests. The adapted version of the AAHPERD is an easily applied, low-cost tool of low risk since it was adapted to the physical and functional conditions of institutionalized older adults. This physical test battery will contribute to the evaluation of older adults and exercise prescription.

    Synesthesia is an unusual condition in which stimulation of one modality evokes sensation or experience in another modality. Although discussed in the literature well over a century ago, synesthesia slipped out of the scientific spotlight for decades because of the difficulty in verifying and quantifying private perceptual experiences. In recent years, the study of synesthesia has enjoyed a renaissance due to the introduction of tests that demonstrate the reality of the condition, its automatic and involuntary nature, and its measurable perceptual consequences. However, while several research groups now study synesthesia, there is no single protocol for comparing, contrasting and pooling synesthetic subjects across these groups. There is no standard battery of tests, no quantifiable scoring system, and no standard phrasing of questions. Additionally, the tests that exist offer no means for data comparison. To remedy this deficit we have devised the Synesthesia Battery. This unified collection of tests is freely accessible online (http://www.synesthete.org). It consists of a questionnaire and several online software programs, and test results are immediately available for use by synesthetes and invited researchers. Performance on the tests is quantified with a standard scoring system. We introduce several novel tests here, and offer the software for running the tests. By presenting standardized procedures for testing and comparing subjects, this endeavor hopes to speed scientific progress in synesthesia research.

    Neuropsychological changes that may occur due to the environmental and psychological stressors of prolonged spaceflight motivated the development of the Cognition Test Battery. The battery was designed to assess multiple domains of neurocognitive functions linked to specific brain systems. Tests included in Cognition have been validated, but not in high-performing samples comparable to astronauts, which is an essential step toward ensuring their usefulness in long-duration space missions. We administered Cognition (on laptop and iPad) and the WinSCAT, counterbalanced for order and version, in a sample of 96 subjects (50% women; ages 25-56 yr) with at least a Master's degree in science, technology, engineering, or mathematics (STEM). We assessed the associations of age, sex, and administration device with neurocognitive performance, and compared the scores on the Cognition battery with those of WinSCAT. Confirmatory factor analysis compared the structure of the iPad and laptop administration methods using Wald tests. Age was associated with longer response times (mean β = 0.12) and less accurate (mean β = -0.12) performance, women had longer response times on psychomotor (β = 0.62), emotion recognition (β = 0.30), and visuo-spatial (β = 0.48) tasks, men outperformed women on matrix reasoning (β = -0.34), and performance on an iPad was generally faster (mean β = -0.55). The WinSCAT appeared heavily loaded with tasks requiring executive control, whereas Cognition assessed a larger variety of neurocognitive domains. Overall results supported the interpretation of Cognition scores as measuring their intended constructs in high performing astronaut analog samples.Moore TM, Basner M, Nasrini J, Hermosillo E, Kabadi S, Roalf DR, McGuire S, Ecker AJ, Ruparel K, Port AM, Jackson CT, Dinges DF, Gur RC.

    Rechargeable lithium ion batteries have wide applications in electronics, where customers always demand more capacity and longer lifetime. Lithium ion batteries have also been considered to be used in electric and hybrid vehicles or even electrical grid stabilization systems. All these applications simulate a dramatic increase in the research and development of battery materials, including new materials, doping, nanostructuring, coatings or surface modifications and novel binders. Consequently, an increasing number of physicists, chemists and materials scientists have recently ventured into this area. Coin cells are widely used in research laboratories to test new battery materials; even for the research and development that target large-scale and high-power applications, small coin cells are often used to test the capacities and rate capabilities of new materials in the initial stage. In 2010, we started a National Science Foundation (NSF) sponsored research project to investigate the surface adsorption and disordering in battery materials (grant no. DMR-1006515). In the initial stage of this project, we have struggled to learn the techniques of assembling and testing coin cells, which cannot be achieved without numerous help of other researchers in other universities (through frequent calls, email exchanges and two site visits). Thus, we feel that it is beneficial to document, by both text and video, a protocol of assembling and testing a coin cell, which will help other new researchers in this field. This effort represents the "Broader Impact" activities of our NSF project, and it will also help to educate and inspire students. In this video article, we document a protocol to assemble a CR2032 coin cell with a LiCoO2 working electrode, a Li counter electrode, and (the mostly commonly used) polyvinylidene fluoride (PVDF) binder. To ensure new learners to readily repeat the protocol, we keep the protocol as specific and explicit as we can. However, it is important

    "Psychologists base the opinions contained in their recommendations, reports and diagnostic or evaluative statements including forensic testimony on information and techniques sufficient to substantiate their findings". Do expert psychodiagnosticians rely in their professional final reports on the materials and raw data obtained from test materials? How ethical are they in their professional performances? In order to answer this question, expert clinical psychologists were given batteries of psychodiagnostic tests, accompanied by one of two different types of background information, suggesting either a Borderline Personality Disorder, or a Paranoid Personality Disorder. This background information was a full and strongly suggestive story in one experiment, and a mere hypothesis in another. All conditions manifested a confirmation bias: the psychodiagnostic reports were profoundly biased by the background suggestions. The present paper focuses on a content analysis of the reports, and shows that the experts referred very little if at all to the psychodiagnostic materials they received. They were found less professional and as a result- less ethical. The ethical relevance of these findings to the teaching and training of professional psychodiagnosticians is discussed, with an emphasis on the importance of teaching students and interns in clinical psychology to base their diagnostic reports on the test data.

    We describe the development and evaluation of a battery of tests of functional visual performance of everyday tasks intended to be suitable for assessment of low vision patients. The functional test battery comprises-Reading rate: reading aloud 20 unrelated words for each of four print sizes (8, 4, 2, & 1 M); Telephone book: finding a name and reading the telephone number; Medicine bottle label: reading the name and dosing; Utility bill: reading the due date and amount due; Cooking instructions: reading cooking time on a food package; Coin sorting: making a specified amount from coins placed on a table; Playing card recognition: identifying denomination and suit; and Face recognition: identifying expressions of printed, life-size faces at 1 and 3 m. All tests were timed except face and playing card recognition. Fourteen normally sighted and 24 low vision subjects were assessed with the functional test battery. Visual acuity, contrast sensitivity, and quality of life (National Eye Institute Visual Function Questionnaire 25 [NEI-VFQ 25]) were measured and the functional tests repeated. Subsequently, 23 low vision patients participated in a pilot randomized clinical trial with half receiving low vision rehabilitation and half a delayed intervention. The functional tests were administered at enrollment and 3 months later. Normally sighted subjects could perform all tasks but the proportion of trials performed correctly by the low vision subjects ranged from 35% for face recognition at 3 m, to 95% for the playing card identification. On average, low vision subjects performed three times slower than the normally sighted subjects. Timed tasks with a visual search component showed poorer repeatability. In the pilot clinical trial, low vision rehabilitation produced the greatest improvement for the medicine bottle and cooking instruction tasks. Performance of patients on these functional tests has been assessed. Some appear responsive to low vision rehabilitation.

    Full Text Available Lifetime testing of batteries for hybrid-electrical vehicles (HEV is usually performed in the lab, either at the cell, module or battery pack level. Complementary field tests of battery packs in vehicles are also often performed. There are, however, difficulties related to field testing of battery-packs. Some examples are cost issues and the complexity of continuously collecting battery performance data, such as capacity fade and impedance increase. In this paper, a novel field test equipment designed primarily for lithium-ion battery cell testing is presented. This equipment is intended to be used on conventional vehicles, not hybrid vehicles, as a cheaper and faster field testing method for batteries, compared to full scale HEV testing. The equipment emulates an HEV environment for the tested battery cell by using real time vehicle sensor information and the existing starter battery as load and source. In addition to the emulated battery cycling, periodical capacity and pulse testing capability are implemented as well. This paper begins with presenting some background information about hybrid electrical vehicles and describing the limitations with today’s HEV battery testing. Furthermore, the functionality of the test equipment is described in detail and, finally, results from verification of the equipment are presented and discussed.

    Full Text Available A general neuropsychological test battery was assembled and individually given to a 98-subject sample, aged 11–12 years old. The battery included some basic and common tests routinely used in the evaluation of language, memory, spatial abilities, concept formation, and praxic abilities. Twenty-five different scores were calculated. A factor analysis with varimax rotation disclosed nine different factors, accounting for about 70% of the variance. Factor I was measured by a Sequential Verbal Memory test and Verbal Fluency subtests (“verbal factor”. Factor II was measured by the Wechsler Memory Scale Visual Memory subtests (immediate and delayed reproduction, and the Rey-Osterrieth Complex Figure (copy and immediate reproduction (“non-verbal memory and constructional factor”. Factor III was measured by the WMS Logical Memory subtests (immediate and delayed; “verbal memory factor”. Factor IV was associated with fine movements (tapping subtests, right and left hand; “fine movements factor”. Factor V was specially measured by the Information subtest of the WMS and the Boston Naming Test (“verbal knowledge”. Factor VI represented a “praxic ability factor” (ideomotor praxis tests. Delayed Associative Learning subtest measured Factor VII; and Digits measured Factor VIII. Factor IX was a “mental control factor” (Mental Control subtest of the Wechsler Memory Scale. The implications of these results to theories relating to the structure of cognitive activity are discussed.

    One of the promising future batteries for electric propulsion of vehicles and ships is the sodium/nickel chloride or ZEBRA (Zero Emission Battery Research Activities) battery. Despite some disadvantages with respect to the high temperature, the advantages with respect to specific energy and energy density are such that, especially in applications where the battery is used on a more or less continuous basis (e.g., in delivery vans and taxies) it is an interesting candidate battery. Another interesting application is on board of ships, like submarines or future electrical surface ships with electric propulsion. In 1995 a 2 year feasibility study, including experimental testing of a 10 kW h battery, was completed. This investigated the naval applicability of the sodium/sulphur battery, which is also a high temperature battery. Here the limited, experimentally proven, life-time of the batteries was of about 1.5 years and this made naval application almost impossible. A paper about this study was presented at the 19th International Power Sources Symposium held at Brighton, England, in April 1995. Because of the more or less comparable specifications on specific energy and the more promising results of the life-time and field tests with sodium/nickel chloride batteries, a ZEBRA battery from AEG Anglo Batteries has been tested for naval applications. This was done by simulating the charge and discharge as it occurs in practice for the applications investigated. With respect to the electrical ship application (investigated for the Royal Netherlands Navy) the power versus time taken from the battery was simulated as well as the charge procedures. The same can be done for the vehicle application: in this case typical drive cycles for a van or taxi are translated to power versus time taken from the battery. The results of the tests for application of the battery in naval ships are very promising. (orig.)

    To examine the efficacy of a short neuromuscular test battery in elderly women suffering from osteoporosis in accordance with the World Health Organization criteria, with and without a history of fractures. Reduced bone mass and a high likelihood of falling increase the risk of osteoporotic fractures. There is a need for neuromuscular tests to identify individuals at risk for falls and fractures. The women were assessed twice. Forty-two women, with a mean age of 70.0 +/- 5.1 (SD) yr, completed the first assessment. The number of postmenopausal fractures and the women's history with regard to agility and falls were assessed. The women performed neuromuscular tests (one-leg stance, tandem walk, and body sway); bone mineral density of the spine and femoral neck were measured. For the follow-up assessment, 13.2 +/- 1.3 mo later, 39 women were studied. The same outcome measurements were obtained at both evaluations. During the observation period, five women fell once and one woman fell twice; there were only two vertebral fractures and no nonvertebral fracture. Neuromuscular performance did not change during this observation period. The median changes in bone mineral density between the two assessments were clinically not relevant. A comparison between patients suffering from established osteoporosis and osteoporotic patients without a history of postmenopausal fractures showed that both groups of patients did not differ with respect to age, neuromuscular performance, bone mineral density, and fear of falling. This neuromuscular test battery is a feasible and practical tool because it is brief and economical to perform. However, its efficacy as a predictor of fractures must be tested in additional studies with a long-term follow-up and a larger group of subjects.

    Experimental bioassays are currently used in ecotoxicology and environmental toxicology to provide information for risk assessment evaluation of new chemicals and to investigate their effects and mechanisms of action; in addition, ecotoxicological models are used for the detection, control and monitoring of the presence of pollutants in the environment. As a single bioassay will never provide a full picture of the quality of the environment, a representative, cost-effective and quantitative test battery should be developed. The effects of pentachlorophenol were studied using a battery of ecotoxicological model systems, including immobilization of Daphnia magna, bioluminiscence inhibition in the bacterium Vibrio fischeri, growth inhibition of the alga Chlorella vulgaris, and micronuclei induction in the plant Allium cepa. The inhibition of cell proliferation and MTT reduction were investigated in Vero cells. Neutral red uptake, cell growth, MTT reduction, lactate dehydrogenase leakage and activity were studied in the salmonid fish cell line RTG-2, derived from the gonad of rainbow trout. Pentachlorophenol was very toxic for all biota and cells. The system most sensitive to pentachlorophenol, was micronuclei induction in A. cepa, followed by D. magna immobilization, bioluminescence inhibition in V. fischeri bacteria at 60 min and cell proliferation inhibition of RTG-2 cells at 72 h. Inhibition of cell proliferation and MTT reduction on Vero monkey cells showed intermediate sensitivity.

    The validity and reliability of a battery of field-based performance tests was examined. The opinions of coaches, fitness professionals and players (n=170, 172 and 101 respectively) on the importance of performance testing were established using a questionnaire. On 2 occasions, separated by 7 days, 80 elite, young soccer players (mean±SD [and range]: age 13.2±2.6 [8.9-19.1] years; stature 1.59±0.18 m [1.32-1.91]; body mass 50.6±17.1 [26.5-88.7] kg) completed a battery of field-based tests comprised of heart rate response to a submaximal Multi-stage fitness test, 3 types of vertical jump, sprints over 10 and 20 m, and an agility test. Physical performance testing was considered important by coaches (97%), fitness professionals (94%) and players (83%). The systematic bias ratio and the random error components of the 95% ratio limits of agreement for the first and second tests, for the U9-U11 vs. U12-U14 vs. U15-U18 age groups, were [Systematic bias (*/÷ ratio limits)]: Heart rate (Level 5): 0.983 (*/÷ 1.044) vs. 0.969 (*/÷ 1.056) vs. 0.983 (*/÷ 1.055); Rocket jump: 0998 (*/÷ 1.112) vs. 0.999 (*/÷ 1.106) vs. 0.996 (*/÷ 1.093); 10 m sprint: 0.997 (*/÷ 1.038) vs. 0.994 (*/÷ 1.033) vs. 0.994 (*/÷ 1.038); Agility test: 1.010 (*/÷1.050) vs. 1.014 (*/÷1.050) vs. 1.002 (*/÷1.053).

    Pragmatic competence may be disrupted due to psychological and neurological causes. For appropriate remedy and rehabilitation, a precise assessment of pragmatic skills is important. However, there is no test battery in the Bengali language, and consequently, there is no published data on pragmatic ability of Bengali speakers. Due to the vast diversity of the population, it becomes increasingly difficult to assess pragmatic ability of an individual without a proper knowledge of the normal variations. To address this problem we have developed a test battery in Bengali, and to begin with, we have administered it to one hundred and five (105) normal healthy persons having different levels of education. The four groups having 17 years and above, 15 to education yielded a normative score of 193, 189, 171 and 150, respectively. These normative scores will allow clinicians to make a proper assessment of patients suffering from pragmatic deficits and help avoid interpreting social differences as neurological deficits.

    The UltraBattery Retrofit Project DP1.8 and Carbon Enriched Project C3, performed by ECOtality North America (ECOtality) and funded by the U.S. Department of Energy and the Advanced Lead Acid Battery Consortium (ALABC), are established to demonstrate the suitability of advanced lead battery technology in hybrid electrical vehicles (HEVs). A profile, termed the “Simulated Honda Civic HEV Profile” (SHCHEVP) has been developed in Project DP1.8 in order to provide reproducible laboratory evaluations of different battery types under real-world HEV conditions. The cycle is based on the Urban Dynamometer Driving Schedule and Highway Fuel Economy Test cycles and simulates operation of a battery pack in a Honda Civic HEV. One pass through the SHCHEVP takes 2,140 seconds and simulates 17.7 miles of driving. A complete nickel metal hydride (NiMH) battery pack was removed from a Honda Civic HEV and operated under SHCHEVP to validate the profile. The voltage behavior and energy balance of the battery during this operation was virtually the same as that displayed by the battery when in the Honda Civic operating on the dynamometer under the Urban Dynamometer Driving Schedule and Highway Fuel Economy Test cycles, thus confirming the efficacy of the simulated profile. An important objective of the project has been to benchmark the performance of the UltraBatteries manufactured by both Furukawa Battery Co., Ltd., Japan (Furakawa) and East Penn Manufacturing Co., Inc. (East Penn). Accordingly, UltraBattery packs from both Furakawa and East Penn have been characterized under a range of conditions. Resistance measurements and capacity tests at various rates show that both battery types are very similar in performance. Both technologies, as well as a standard lead-acid module (included for baseline data), were evaluated under a simple HEV screening test. Both Furakawa and East Penn UltraBattery packs operated for over 32,000 HEV cycles, with minimal loss in performance; whereas the

    A multisite study investigated the test-retest reliability and practice effects of a battery of assessments to measure neurocognitive function in individuals with Down syndrome (DS). The study aimed to establish the appropriateness of these measures as potential endpoints for clinical trials. Neurocognitive tasks and parent report measures comprising the Arizona Cognitive Test Battery (ACTB) were administered to 54 young participants with DS (7-20 years of age) with mild to moderate levels of intellectual disability in an initial baseline evaluation and a follow-up assessment 3 months later. Although revisions to ACTB measures are indicated, results demonstrate adequate levels of reliability and resistance to practice effects for some measures. The ACTB offers viable options for repeated testing of memory, motor planning, behavioral regulation, and attention. Alternative measures of executive functioning are required.

    This year's applicants to medical school took a newly revised version of the Medical College Admission Test. Unlike applicants in the past, they were asked to demonstrate their knowledge and use of concepts commonly taught in introductory psychology courses. The new Psychological, Social, and Biological Foundations of Behavior Test asked applicants to demonstrate the ways in which psychological, social, and biological factors influence perceptions and reactions to the world; behavior and behavior change; what people think about themselves and others; the cultural and social differences that influence well-being; and the relationships among social stratification, access to resources, and well-being. Building from the classic biopsychosocial model, this article provides the rationale for testing psychology concepts in application to medical school. It describes the concepts and skills that the new exam tests and shows how they lay the foundation for learning in medical school about the behavioral and sociocultural determinants of health. This article discusses the implications of these changes for undergraduate psychology faculty and psychology curricula as well as their importance to the profession of psychology at large.

    The Energy Systems Test Area (ESTA) at the Lyndon B. Johnson Space Center in Houston, Texas conducts development and qualification tests to fulfill Energy System Division responsibilities relevant to ASA programs and projects. EST A has historically called upon a variety of fluid, mechanical, electrical, environmental, and data system capabilities spread amongst five full-service facilities to test human and human supported spacecraft in the areas of propulsion systems, fluid systems, pyrotechnics, power generation, and power distribution and control systems. Improvements at ESTA are being made in full earnest of offering NASA project offices an option to choose a thorough test regime that is balanced with cost and schedule constraints. In order to continue testing of enabling power-related technologies utilized by the Energy System Division, an especially proactive effort has been made to increase the cost effectiveness and schedule responsiveness for battery testing. This paper describes the continuous improvement in battery testing at the Energy Systems Test Area being made through consolidation, streamlining, and standardization.

    The Cambridge Neuropsychological Test Automated Battery (CANTAB) is frequently used in research protocols and increasingly in clinical practice. Despite the frequency of its use, important aspects of its measurement validity have yet to be established in healthy adults. Two hundred and fifty-five individuals completed the CANTAB and traditional neuropsychological tests commonly used in clinical practice, including selected subtests from the Wechsler Adult Intelligence Scale, Controlled Oral Word Association Test, Animal Naming, Trail Making Tests A and B, the Stroop test, and the Green Story Recall test. Results showed that CANTAB subtests were modestly correlated with traditional subtests. Correlations between CANTAB subtests and traditional subtests were less consistent when age and education were controlled for. In conclusion, the CANTAB shows modest associations with traditional neuropsychological test measures.

    Schaeck, S.; Stoermer, A. O.; Albers, J.; Weirather-Koestner, D.; Kabza, H.

    In the first part of this work [1] selected key parameters for applying lead-acid (LA) batteries in micro-hybrid power systems (MHPS) were investigated. Main results are integrated in an accelerated, comprehensive test proposal presented here. The test proposal aims at a realistic representation of the pSoC operation regime, which is described in Refs. [1,6]. The test is designed to be sensitive with respect to dynamic charge acceptance (DCA) at partially discharged state (critical for regenerative braking) and the internal resistance at high-rate discharge (critical for idling stop applications). First results are presented for up-to-date valve-regulated LA batteries with absorbent glass mat (AGM) separators. The batteries are close to the limits of the first proposal of pass/fail-criteria. Also flooded batteries were tested; the first out of ten units failed already.

    Advanced battery technology evaluations are performed under simulated electric vehicle operating conditions at Argonne National Laboratory's & Diagnostic Laboratory (ADL). The ADL provide a common basis for both performance characterization and life evaluation with unbiased application of tests and analyses. This paper summarizes the performance characterizations and life evaluations conducted in 1991 on twelve single cells and eight 3- to 360-cell modules that encompass six battery technologies (Na/S, Li/MS, Ni/MH, Zn/Br, Ni/Fe, and Pb-Acid). These evaluations were performed for the Department of Energy, Office of Transportation Technologies, Electric and Hybrid Propulsion Division. The results measure progress in battery R & D programs, compare battery technologies, and provide basic data for modeling and continuing R & D to battery users, developers, and program managers.

    Preoperative psychological screening of bariatric surgery candidates has become routine, and a significant proportion of patients have their surgery deferred as a consequence. If psychological testing is being used as a form of preoperative triage, both patients and surgeons are entitled to know whether there is sufficient evidence to justify its use in this way. We define the argument for psychological screening as consisting of four premises (p1-p4) and a conclusion (C) as follows: (p1) A significant minority of obese patients will not be successful in losing weight following bariatric surgery-the "failure" group; (p2) A significant minority of patients will exhibit abnormal psychological profiles during preoperative testing; (p3) The majority of individuals referred to in (p2) will be found in group (p1) i.e., abnormal psychological profiles identified preoperatively predict less favorable weight loss outcomes postoperatively; (p4) Identifying patients with adverse psychological profiles preoperatively would allow either exclusion of those at high risk of failure or provide a more secure rationale for targeted pre- and postoperative support; (C) Psychological screening should be part of the routine preoperative assessment for patients undergoing obesity surgery. We reviewed the literature to find evidence to support the premises and show that (p1) can be justified but that (p2) is problematic and can only be accepted in a heavily qualified version. We find no evidence for (p3) and since (p4) and (C) are predicated on (p3), the argument clearly fails. There is no evidence to suggest that preoperative psychological screening can predict postoperative outcomes and no justification for using such testing as a means of discriminating between candidates presenting themselves for bariatric surgery.

  15. Cognitive test batteries in animal cognition research: evaluating the past, present and future of comparative psychometrics.

    For the past two decades, behavioural ecologists have documented consistent individual differences in behavioural traits within species and found evidence for animal "personality". It is only relatively recently, however, that increasing numbers of researchers have begun to investigate individual differences in cognitive ability within species. It has been suggested that cognitive test batteries may provide an ideal tool for this growing research endeavour. In fact, cognitive test batteries have now been used to examine the causes, consequences and underlying structure of cognitive performance within and between many species. In this review, we document the existing attempts to develop cognitive test batteries for non-human animals and review the claims that these studies have made in terms of the structure and evolution of cognition. We argue that our current test battery methods could be improved on multiple fronts, from the design of tasks, to the domains targeted and the species tested. Refining and optimising test battery design will provide many benefits. In future, we envisage that well-designed cognitive test batteries may provide answers to a range of exciting questions, including giving us greater insight into the evolution and structure of cognition.

    The purpose of this study was to determine if an on-site test battery would distinguish among three levels of giant slalom skiing ability. The test battery consisted of a 20-m shuttle run test, Wingate 60s cycling test, hexagonal obstacle test, high box test, double leg jumping test and vertical jump test. These tests were selected since previous studies have identified aerobic endurance, anaerobic endurance, power and agility as important components for Alpine skiers. Both construct validity and criterion related validity of the test battery were examined using data from 11 club skiers, 14 divisional level skiers, and 9 provincial level skiers. To establish construct validity, univariate F tests examined differences among the three levels of skiers. Significant (P less than 0.05) differences were found between the club skiers and the better skiers (divisional and provincial level) for the following test variables: peak power, mean power, and post-exercise lactate for a 60s Wingate cycle ergometer test, high box test, hexagonal obstacle test, double leg jumping test, and shuttle run test. Criterion related validity was established since there were significant correlations between giant slalom performance time and the hexagonal obstacle test (r = 0.82), high box test (r = -0.80), and double leg jumping (r = -0.86). These data illustrate that an on-site test battery can be used to distinguish among giant slalom Alpine skiers.

    Physical fitness is a powerful health marker in childhood and adolescence, and it is reasonable to think that it might be just as important in younger children, i.e. preschoolers. At the moment, researchers, clinicians and sport practitioners do not have enough information about which fitness tests are more reliable, valid and informative from the health point of view to be implemented in preschool children. Our aim was to systematically review the studies conducted in preschool children using field-based fitness tests, and examine their (1) reliability, (2) validity, and (3) relationship with health outcomes. Our ultimate goal was to propose a field-based physical fitness-test battery to be used in preschool children. PubMed and Web of Science. Studies conducted in healthy preschool children that included field-based fitness tests. When using PubMed, we included Medical Subject Heading (MeSH) terms to enhance the power of the search. A set of fitness-related terms were combined with 'child, preschool' [MeSH]. The same strategy and terms were used for Web of Science (except for the MeSH option). Since no previous reviews with a similar aim were identified, we searched for all articles published up to 1 April 2014 (no starting date). A total of 2,109 articles were identified, of which 22 articles were finally selected for this review. Most studies focused on reliability of the fitness tests (n = 21, 96%), while very few focused on validity (0 criterion-related validity and 4 (18%) convergent validity) or relationship with health outcomes (0 longitudinal and 1 (5%) cross-sectional study). Motor fitness, particularly balance, was the most studied fitness component, while cardiorespiratory fitness was the least studied. After analyzing the information retrieved in the current systematic review about fitness testing in preschool children, we propose the PREFIT battery, field-based FITness testing in PREschool children. The PREFIT battery is composed of the following

    The primary objective of this study was to determine the structural and known-group validity as well as the inter-rater reliability of a test battery to evaluate the motor control of the craniofacial region. Seventy volunteers without TMD and 25 subjects with TMD (Axes I) per the DC/TMD were asked to execute a test battery consisting of eight tests. The tests were video-taped in the same sequence in a standardised manner. Two experienced physical therapists participated in this study as blinded assessors. We used exploratory factor analysis to identify the underlying component structure of the eight tests. Internal consistency (Cronbach's α), inter-rater reliability (intra-class correlation coefficient) and construct validity (ie, hypothesis testing-known-group validity) (receiver operating curves) were also explored for the test battery. The structural validity showed the presence of one factor underlying the construct of the test battery. The internal consistency was excellent (0.90) as well as the inter-rater reliability. All values of reliability were close to 0.9 or above indicating very high inter-rater reliability. The area under the curve (AUC) was 0.93 for rater 1 and 0.94 for rater two, respectively, indicating excellent discrimination between subjects with TMD and healthy controls. The results of the present study support the psychometric properties of test battery to measure motor control of the craniofacial region when evaluated through videotaping. This test battery could be used to differentiate between healthy subjects and subjects with musculoskeletal impairments in the cervical and oro-facial regions. In addition, this test battery could be used to assess the effectiveness of management strategies in the craniofacial region. © 2017 John Wiley & Sons Ltd.

    Apart from the cranio-cervical flexion test and the deep neck flexor endurance test, evidence related to reliability of cervical movement control dysfunction tests is lacking. This study investigated the inter- and intra-tester reliability of a battery of cervical movement control dysfunction tests and the effect of clinician experience on reliability in 15 patients with chronic neck pain and 17 non-neck pain controls. In addition, it explored whether impaired performance on this battery of tests was more frequently observed in the neck pain group. Inter and intra-tester reliability study. Participants were videotaped while performing a battery of nine active cervical movement control dysfunction tests. Two physiotherapists, with different levels of experience, independently rated all tests on two occasions two weeks apart. They were masked to participants' neck pain or non-neck pain status. Inter-tester reliability for the complete battery of tests was substantial (κ = 0.69; 95% CI: 0.62, 0.76). Intra-rater reliability values for the expert (κ = 0.86; 95% CI: 0.79, 0.92) and novice (κ = 0.76; 95% confidence intervals (CI): 0.68, 0.84) were overall comparable suggesting that novices can achieve good accuracy with the battery of tests if trained. The frequency of impaired performances in cervical movement control dysfunction tests was low and comparable between groups. Only two tests achieved a greater number of impaired ratings in the patient group. Although reliable, further research in larger neck pain populations is required to explore this battery of tests, in order to establish their diagnostic accuracy for identifying clinically relevant cervical movement control dysfunction.

    The Assessing Levels of Physical Activity (ALPHA) health-related fitness test battery is a set of reliable, valid, and feasible tests to assess health-related physical fitness in children and in adolescents. The aim of this study was to examine the reliability of this battery in adolescents with Down syndrome (DS). The extended ALPHA health-related fitness test battery was performed twice within 1 month in 17 apparently healthy adolescents, aged 12-18 years, with DS who had an intelligence quotient ≥ 35. Intraclass correlation coefficient (ICC) was used to determinate test-retest reliability, and nonparametric Wilcoxon signed rank test was used to compare mean differences between measurements. With the exception of subscapular skinfold test, which obtained a moderate agreement (ICC = 0.64), all tests had a very high reliability: the 20-m shuttle-run test (ICC = 0.86), the right handgrip strength test (ICC = 0.86), the left handgrip strength test (ICC = 0.86), the standing broad jump test (ICC = 0.85), body mass index (ICC = 0.95), waist circumference (ICC = 0.98), triceps skinfold (ICC = 0.85), and the 4 × 10-m shuttle-run test (ICC = 0.92). There were no significant differences (all p > 0.05) in any of the tests. The ALPHA health-related fitness battery is reliable for measuring health-related components of fitness in adolescents with DS.

    This study aims to report the minimum test battery needed to screen non-strabismic binocular vision anomalies (NSBVAs) in a community set-up. When large numbers are to be screened we aim to identify the most useful test battery when there is no opportunity for a more comprehensive and time-consuming clinical examination. The prevalence estimates and normative data for binocular vision parameters were estimated from the Binocular Vision Anomalies and Normative Data (BAND) study, following which cut-off estimates and receiver operating characteristic curves to identify the minimum test battery have been plotted. In the receiver operating characteristic phase of the study, children between nine and 17 years of age were screened in two schools in the rural arm using the minimum test battery, and the prevalence estimates with the minimum test battery were found. Receiver operating characteristic analyses revealed that near point of convergence with penlight and red filter (> 7.5 cm), monocular accommodative facility ( 1.25 prism dioptres) were significant factors with cut-off values for best sensitivity and specificity. This minimum test battery was applied to a cohort of 305 children. The mean (standard deviation) age of the subjects was 12.7 (two) years with 121 males and 184 females. Using the minimum battery of tests obtained through the receiver operating characteristic analyses, the prevalence of NSBVAs was found to be 26 per cent. Near point of convergence with penlight and red filter > 10 cm was found to have the highest sensitivity (80 per cent) and specificity (73 per cent) for the diagnosis of convergence insufficiency. For the diagnosis of accommodative infacility, monocular accommodative facility with a cut-off of less than seven cycles per minute was the best predictor for screening (92 per cent sensitivity and 90 per cent specificity).

    Forero Camacho Oscar Mauricio

    2016-01-01

    Full Text Available Electric Vehicles (EV technologies are still relatively new and under strong development. Although some standardized solutions are being promoted and becoming a new trend, there is an outstanding need for common platforms and sharing of knowledge and core technologies. This paper presents the development of a test platform, including three Li-ion batteries designed for EV applications, and three associated bi-directional power converters, for testing impacts on different advanced loadings of EV batteries. Different charging algorithms/profiles have been tested, including constant current and power, and forced and pulsed power. The aim of the tests has been to study the impact of smart charging and fast charging on the power system, on the battery state of health and degradation, and to find out the limitations of the batteries for a Smart Grid. The paper outlines the advantages and disadvantages of both tests in terms of regulation of the aggregated local power, power capacity and the power exchange with the grid. The smart charging tests performed have demonstrated that even with a simple control algorithm, without any forecasting, it is possible to provide the required charging and at the same time the power system services, reducing the peak power and the energy losses in the power connection line of the power exchange with the national grid.

    Karami, Hassan; Karimi, Mohammad Ali; Mahdipour, Maryam

    A cold cranking test for 17 sealed lead-acid batteries with grids of lead-calcium alloy at -18 °C was performed at different discharge currents. Time-voltage behavior of the batteries during 10 s discharge, voltage values at discharge times of 30, 60 and 90 s, and time of discharge to reach a final voltage of 6 V are critical points in the cold cranking test. These were modeled by artificial neural networks in MATLAB 7 media. Nine discharge currents were used for the training set, five discharge currents for the prediction set and three discharge currents for the validation set. Maximum prediction errors in the modeling of the time-voltage behavior during a 10 s discharge (model 1), the voltage of critical points of 30, 60, 90 s (model 2) and the time to reach a final voltage of 6 V (model 3) were under 3.1%, 3.3%, and 3.5%, respectively for each model. The results obtained showed that the models can be used in the battery industry for the prediction of the cold cranking behavior of lead-acid batteries at high discharge currents based on experimental cold cranking data at low discharge currents without the use of expensive and complex instruments. A file (EXE file) based on the model obtained by WinNN 32 was prepared to enable inexpert operators in the lead-acid battery industry to use the method.

    Neurocognitive assessment in individuals with intellectual disabilities requires a well-validated test battery. To meet this need, the Arizona Cognitive Test Battery (ACTB) has been developed specifically to assess the cognitive phenotype in Down syndrome (DS). The ACTB includes neuropsychological assessments chosen to 1) assess a range of skills, 2) be non-verbal so as to not confound the neuropsychological assessment with language demands, 3) have distributional properties appropriate for research studies to identify genetic modifiers of variation, 4) show sensitivity to within and between sample differences, 5) have specific correlates with brain function, and 6) be applicable to a wide age range and across contexts. The ACTB includes tests of general cognitive ability and prefrontal, hippocampal and cerebellar function. These tasks were drawn from the Cambridge Neuropsychological Testing Automated Battery (CANTAB) and other established paradigms. Alongside the cognitive testing battery we administered benchmark and parent-report assessments of cognition and behavior. Individuals with DS (n=74, ages 7-38 years) and mental age (MA) matched controls (n=50, ages 3-8 years) were tested across 3 sites. A subsample of these groups were used for between-group comparisons, including 55 individuals with DS and 36 mental age matched controls. The ACTB allows for low floor performance levels and participant loss. Floor effects were greater in younger children. Individuals with DS were impaired on a number ACTB tests in comparison to a MA-matched sample, with some areas of spared ability, particularly on tests requiring extensive motor coordination. Battery measures correlated with parent report of behavior and development. The ACTB provided consistent results across contexts, including home vs. lab visits, cross-site, and among individuals with a wide range of socio-economic backgrounds and differences in ethnicity. The ACTB will be useful in a range of outcome studies

    Though the benefits of early detection of breast cancer are generally known, only few women attend breast-screening examinations. The study was designed to gain insight into the problem by exploring the psychological profile of clinic attenders. In order to find out whether there is such a profile, 210 self-referred women were compared with 210 nonattending women, from the same working and social environments, matched in age, education and occupational level. All subjects were administered 10 tests in 7 domains. The tests were administered as part of a health survey. The results showed that clinic attenders scored higher on negative emotions and total emotions and lower on positive emotions; higher on repression; lower on daydreams; lower on range of self-concept, references to others and negative self-references but higher on positive self-references; scored higher on self-references describing oneself in a functional and in a passive way and scored lower on those describing oneself in terms of one's attitudes, body and appearance; scored lower on neuroticism; scored lower on different somatic complaints and health orientation but higher in alexithymia. No differences were found in authoritarianism, locus of control and self-complexity. Conclusions are that there is a psychological profile of clinic attenders, that it is focused on dysphoric emotions, psychological disease promotion and defensiveness and that it includes characteristics of the construct that is sometimes called the cancer-prone personality.

  9. Psychological testing and the German labor market, 1925 to 1965.

    From the 1920s to the 1950s, the massive German Labor Administration used loosely standardized, pragmatic evaluations of personality to steer young people into appropriate jobs. Starting in the late 1950s, the Administration shifted to American scientific methods of trait and factor psychological testing. Behind this change lay not a change in academic psychology but a power shift in the German labor market. Originally, the Labor Administration had to appeal to employers, for whom pragmatic evaluations of personality seemed most convincing. Thanks to the Economic Miracle in the 1950s, the Administration had to gain the trust of young Germans, their parents, and the public, who, it was hoped, would be won over by science.

    1973-01-01

    A set of 36 relatively independent categories of human performance were identified. These categories encompass human performance in the cognitive, perceptual, and psychomotor areas, and include diagnostic measures and sensitive performance metrics. Then a prototype standardized test battery was constructed, and research was conducted to obtain information on the sensitivity of the tests to stress, the sensitivity of selected categories of performance degradation, the time course of stress effects on each of the selected tests, and the learning curves associated with each test. A research project utilizing a three factor partially repeated analysis of covariance design was conducted in which 60 male subjects were exposed to variations in noise level and quality during performance testing. Effects of randomly intermittent noise on performance of the reaction time tests were observed, but most of the other performance tests showed consistent stability. The results of 14 analyses of covariance of the data taken from the performance of the 60 subjects on the prototype standardized test battery provided information which will enable the final development and test of a standardized test battery and the associated development of differential sensitivity metrics and diagnostic classificatory system.

  17. Time-frequency Representations Application in Psychological Testing

    Directory of Open Access Journals (Sweden)

    REIZ Romulus

    2015-10-01

    Full Text Available A psychological test is a test that is designed to measure one aspect of human behavior. These tests are usually designed to evaluate a person’s ability to complete tasks that were individual's performance on certain tasks that have usually been requested in advance. Usually a test score is used to compare with other results to measure the individual’s performance regarding cognitive ability, aptitude, personality, etc. One such test is the so called “finger tapping” test, designed to measure the integrity of the neuromuscular system and examine motor control. There are several ways to perform such a test. The purpose of this paper isn’t to study the finger tapping test which is well documented in the literature, but to develop if possible a simple way of performing such a test. Using the method presented in the paper a nonstationary signal was obtained and it was analyzed using the Short-time Fourier time frequency representation to obtain the signals frequency and its variation in time. The results presented in the paper show that this method can be used to perform the test and the frequency and spatial amplitude of the obtained tapping signal can be determined easily.

    The aim of this study was to validate a new paper and pencil test battery to diagnose minimal hepatic encephalopathy (MHE) in Korea. A new paper and pencil test battery was composed of number connection test-A (NCT-A), number connection test-B (NCT-B), digit span test (DST), and symbol digit modality test (SDMT). The norm of the new test was based on 315 healthy individuals between the ages of 20 and 70 years old. Another 63 healthy subjects (n = 31) and cirrhosis patients (n = 32) were included as a validation cohort. All participants completed the new paper and pencil test, a critical flicker frequency (CFF) test and computerized cognitive function test (visual continuous performance test [CPT]). The scores on the NCT-A and NCT-B increased but those of DST and SDMT decreased according to age. Twelve of the cirrhotic patients (37.5%) were diagnosed with MHE based on the new paper and pencil test battery. The total score of the paper and pencil test battery showed good positive correlation with the CFF (r = 0.551, P battery including NCT-A, NCT-B, DST, and SDMT showed good correlation with neuropsychological tests.

    Despite acceptance that risk for alcohol-use disorder (AUD) has a large genetic component, the identification of genes underlying various components of risk for AUD has been hampered in humans, in part by the heterogeneity of expression of the phenotype. One aspect of AUD is physical dependence. Alcohol withdrawal is a serious consequence of alcohol dependence with multiple symptoms, many of which are seen in multiple species, and can be experienced over a wide-ranging time course. In the present three studies, we developed a battery of withdrawal tests in mice, examining behavioral symptoms from multiple domains that could be measured over time. To permit eventual use of the battery in different strains of mice, we used male and female mice of a genetically heterogeneous stock developed from intercrossing eight inbred strains. Withdrawal symptoms were assessed using commonly used tests after administration of ethanol in vapor for 72 continuous hours. We found significant effects of ethanol withdrawal versus air-breathing controls on nearly all symptoms, spanning 4 days following ethanol vapor inhalation. Withdrawal produced hypothermia, greater neurohyperexcitability (seizures and tremor), anxiety-like behaviors using an apparatus (such as reduced transitions between light and dark compartments), anhedonia (reduced sucrose preference), Straub tail, backward walking, and reductions in activity; however, there were no changes in thermal pain sensitivity, hyper-reactivity to handling, or anxiety-like emergence behaviors in other apparatus. Using these data, we constructed a refined battery of withdrawal tests. Individual differences in severity of withdrawal among different tests were weakly correlated at best. This battery should be useful for identifying genetic influences on particular withdrawal behaviors, which should reflect the influences of different constellations of genes.

    2014-06-01

    Full Text Available Background: The purpose of this article is to draw attention to a significant role of social approval variable in the qustionnairebased diagnosis of drivers' psychological aptitude. Material and Methods: Three questionnaires were used: Formal Characteristics of Behavior - Temperament Inventory (FCB-TI, Eysenck Personality Questionnaire (EPQ-R(S and Impulsiveness Questionnaire (Impulsiveness, Venturesomeness, Empathy - IVE. Three groups of drivers were analyzed: professional "without crashes" (N = 46, nonprofessional "without crashes" (N = 75, and nonprofessional "with crashes" (N = 75. Results: Nonprofessional drivers "without crashes" significantly stood up against other drivers. Their personality profile, indicating a significantly utmost perseveration, emotional reactivity, neuroticism, impulsiveness and the lowest endurance did not fit in to the requirements to be met by drivers. The driver safety profile was characteristic of professional drivers (the lowest level of perseveration, impulsiveness and neuroticism and the highest level of endurance. Similar profile occurred among nonprofessional drivers - the offenders of road crashes. Compared to the nonprofessional "without crashes" group, professional drivers and offenders of road crashes were also characterized by a significantly higher score on the Lie scale, determining the need for social approval. This is likely to result from the study procedure according to which the result of professional drivers testing had an impact on a possible continuity of their job and that of nonprofessional drivers "with crashes" decided about possible recovery of the driving license. Conclusions: The variable of social approval can be a significant artifact in the study of psychological drivers' testing and reduce the reliability of the results of questionnaire methods.

  17. Results of the ESA study on psychological selection of astronaut applicants for Columbus missions I: Aptitude testing

    Science.gov (United States)

    Fassbender, Christoph; Goeters, Klaus-Martin

    European participation in the Space Station Freedom brought about new challenges for the psychological selection of astronaut candidates, particularly in respect to specific demands of long duration space flights. For this reason existing selection criteria and methods were reassessed. On these grounds a study was undertaken applying a unique composition of aptitude tests to a group of 97 ESA scientists and engineers who are highly comparable to the expected astronaut applicants with respect to age and education. The tests assessed operational aptitudes such as logical reasoning, memory function, perception, spatial orientation, attention, psychomotor function, and multiple task capacity. The study goals were: 1) Verification of psychometric qualities and applicability of tests in a normative group; 2) Search for culture-fair tests by which multi-national groups can be examined; 3) Identification of test methods which consider general and special operational demands of long duration space flights. Based on the empirical findings a test battery was arranged for use in the selection of ESA astronaut applicants. Results showed that 16 out of the 18 employed tests have good psychometric qualities and differentiate reliably in the special group of testees. The meta structure of the test battery as described by a factorial analysis is presented. Applicability of tests was generally high. Tests were culture-fair, however, a relation between English language skills and test results was identified. Since most item material was language-free, this was explained with the importance of English language skills for the understanding of test instructions. Solutions to this effect are suggested.

J Strength Cond Res XX(X): 000-000, 2017-This study assessed the interday reliability of a testing battery for the assessment of physical qualities of rugby league players. Fifty players (age 17.1 ± 1.1 years; stature 181.3 ± 6.3 cm; and body mass 89.0 ± 11.6 kg) from 3 Super League academies participated in this study. Tests of countermovement jump performance, 10- and 20-m sprint performance, change of direction, medicine ball throw, and a modified Yo-Yo Intermittent Recovery Test Level 1 (prone Yo-Yo IR1) were completed on 3 separate occasions. Between-day intraclass correlation coefficient, typical error (TE), coefficient of variation, and the smallest worthwhile change (SWC) were calculated to determine the reliability and sensitivity of each measure. Individual tests (except medicine ball throw) were not systematically different between trials (p > 0.05), with an interday variability that was <10%. In all instances, the TE was larger than the calculated SWC change, although variability was less than that typically observed after a training intervention or specific training period (i.e., preseason). Using a magnitude-based inference approach, we present the required change for all performance tests to be 75% confident and the change is beneficial. This simple and time efficient testing battery is sufficiently reliable to detect previously observed changes in a range of physical qualities of rugby league players.

    The seismic-fragility response of naturally-aged nuclear station safety-related batteries is of interest for two reasons: (1) to determine actual failure modes and thresholds and (2) to determine the validity of using the electrical capacity of individual cells as an indicator of the potential survivability of a battery given a seismic event. Prior reports in this series discussed the seismic-fragility tests and results for three specific naturally-aged cell types: 12-year old NCX-2250, 10-year old LCU-13, and 10-year old FHC-19. This report focuses on the complementary approach, namely, the seismic-fragility response of accelerated-aged batteries. Of particular interest is the degree to which such approaches accurately reproduce the actual failure modes and thresholds. In these tests the significant aging effects observed, in terms of seismic survivability, were: embrittlement of cell cases, positive bus material and positive plate grids; and excessive sulphation of positive plate active material causing hardening and expansion of positive plates. The IEEE Standard 535 accelerated aging method successfully reproduced seismically significant aging effects in new cells but accelerated grid embrittlement an estimated five years beyond the conditional age of other components.

    Battery testing procedures are important for understanding battery performance, including degradation over the life of the battery. Standards are important to provide clear rules and uniformity to an industry. The work described in this report addresses the need for standard battery testing procedures that reflect real-world applications of energy storage systems to provide regulation services to grid operators. This work was motivated by the need to develop Vehicle-to-Grid (V2G) testing procedures, or V2G drive cycles. Likewise, the stationary energy storage community is equally interested in standardized testing protocols that reflect real-world grid applications for providing regulation services. As the first of several steps toward standardizing battery testing cycles, this work focused on a statistical analysis of frequency regulation signals from the Pennsylvania-New Jersey-Maryland Interconnect with the goal to identify patterns in the regulation signal that would be representative of the entire signal as a typical regulation data set. Results from an extensive time-series analysis are discussed, and the results are explained from both the statistical and the battery-testing perspectives. The results then are interpreted in the context of defining a small set of V2G drive cycles for standardization, offering some recommendations for the next steps toward standardizing testing protocols.

    Although visual recognition memory and visuospatial paired associates learning has been shown to be impaired in amnestic mild cognitive impairment (aMCI), the sensitivity and specificity of the visual memory tests used to identify aMCI are not well defined. The current study attempted to analyze the sensitivity and specificity of three visual episodic memory tests (Pattern Recognition Memory [PRM], Delayed Matching to Sample [DMS], and Paired Associated Learning [PAL]) from the CANTAB, in differentiating aMCI patients from control healthy participants. Seventy seven aMCI patients and 85 cognitive normal controls aged over 50 years performed the PRM, DMS, and PAL tests. Univariate and multivariate logistic regression and receiver operating characteristic curve analyses were used to study the relationships between aMCI and visual memory measures. The three Cambridge Neuropsychological Test Automated Battery measures significantly predicted aMCI. The optimal predictive model combined the total percent correct responses for PRM and DMS with the PAL total errors (six shapes adjusted), with a sensitivity of 72%, specificity of 83%, and achieved predictive accuracy of 80%. Visual episodic memory tasks such as those involved in the PRM, DMS, and PAL tests (included in the Cambridge Neuropsychological Test Automated Battery) may sensitively discriminate aMCI patients from normal controls. These tests may be useful for correct diagnosis of aMCI. Copyright © 2013 John Wiley & Sons, Ltd.

    Salvia officinalis (sage) has previously been shown both to possess in vitro cholinesterase inhibiting properties, and to enhance mnemonic performance and improve mood in healthy young participants. In this double-blind, placebo-controlled, crossover study, 30 healthy participants attended the laboratory on three separate days, 7 days apart, receiving a different treatment in counterbalanced order on each occasion (placebo, 300, 600 mg dried sage leaf). On each day mood was assessed predose and at 1 and 4 h postdose. Each mood assessment comprised completion of Bond-Lader mood scales and the State Trait Anxiety Inventory (STAI) before and after 20 min performance of the Defined Intensity Stress Simulator (DISS) computerized multitasking battery. In a concomitant investigation, an extract of the sage leaf exhibited dose-dependent, in vitro inhibition of acetylcholinesterase and, to a greater extent, butyrylcholinesterase. Both doses of sage led to improved ratings of mood in the absence of the stressor (that is, in pre-DISS mood scores) postdose, with the lower dose reducing anxiety and the higher dose increasing 'alertness', 'calmness' and 'contentedness' on the Bond-Lader mood scales. The reduced anxiety effect following the lower dose was, however, abolished by performing the DISS, with the same dose also being associated with a reduction of alertness during performance. Task performance on the DISS battery was improved for the higher dose at both postdose sessions, but reduced for the lower dose at the later testing session. The results confirm previous observations of the cholinesterase inhibiting properties of S. officinalis, and improved mood and cognitive performance following the administration of single doses to healthy young participants.

    The auditory speech sounds evaluation 2009 test battery for assessment of speech pitch perception is presented. It was designed to (a) assess perception of pitch in linguistic contexts without the confounds of secondary acoustic cues, (b) be usable with listeners from different language backgrounds, and (c) be suitable for use in a clinical setting. The need for this test battery arises from increased awareness of the importance of prosody in clinical practice, and the development of methods for improving pitch perception in listeners with profound hearing losses. Identification and discrimination tasks based on linguistic contexts were developed to establish listeners' just noticeable differences (JNDs) for pitch changes. Stimuli were pseudosentences and pseudowords based on speech from a female speaker, overlain with stylized pitch contours. Target pitch excursions were varied from the 200 Hz baseline to a maximum of 349 Hz. Ninety normal-hearing listeners participated in test validation that assessed goals (a)-(c), established test-retest reliability, and gathered normative data. The JNDs on non-linguistic, control tasks were lower than on linguistic ones, showing that non-linguistic tasks may overestimate pitch perception in speech. Listeners from different language backgrounds scored comparably on most linguistic tasks, and test-retest differences were non-significant. Test usability as evidenced by task duration and subject experience seemed satisfactory for clinical use.

    The aim of this study was to investigate the hierarchical contributions of anthropometry, strength and cognition to a battery of prescriptive and reactive agility tests. Nineteen participants (mean±S.D.; age:22.1±1.9 years; height: 182.9±5.5 cm; body mass: 77±4.9 kg) completed four agility tests: a prescriptive linear sprint, a prescriptive change-of-direction sprint, a reactive change-of-direction sprint, and a reactive linear deceleration test. Anthropometric variables included body fat percentage and thigh girth. Strength was quantified as the peak eccentric hamstring torque at 180, 300, and 60°·s-1. Mean reaction time and accuracy in the Stroop word-colour Test was used to assess perceptual and decision making factors. There was little evidence of intertest correlation with the strongest relationship observed between 10 m sprint and t-test performance (r2=0.49, Pagility, accounting for a maximum 23% (P=0.12) in the prescriptive change-of-direction test. Cognitive measures had a stronger correlation with the reactive (rather than prescriptive) agility tests, with a maximum 33% (P=0.04) of variance accounted for in the reactive change-of-direction test. Eccentric hamstring strength accounted for 62% (P=0.01) of the variance in the prescriptive change-of-direction test. Hierarchical ordering of the agility tests revealed that eccentric hamstring strength was the primary predictor in 3 of the 4 tests, with cognitive accuracy the next most common predictor. There is little evidence of inter-test correlation across a battery of agility tests. Eccentric hamstring strength and decision making accuracy are the most common predictors of agility performance.

    The neuropsychological investigation of semantic memory has mainly focused on concrete concepts, while abstract concepts have been relatively neglected. We describe a new battery for assessing abstract concepts in brain-damaged patients. The battery includes three different tests: an association task, a multiplechoice naming-to-description task and a sentence completion task. The three tasks are based on the same 40 stimuli belonging to different categories of abstract concepts and they are tightly controlled for variables that can account for quantitative differences between abstract concepts (i.e. concreteness, imageability, context availability, familiarity, age of acquisition, mode of acquisition, emotional valence and arousal). The three tasks showed high reliability. Normative data were collected from 108 healthy Italian adults. To assess its sensitivity, the battery was administered to 13 patients with probable Alzheimer's disease who performed worse than matched controls. Significant correlations were also found between the tests and other semantic memory tests, supporting the validity of the battery.

    The List Sorting Working Memory Test was designed to assess working memory (WM) as part of the NIH Toolbox Cognition Battery. List Sorting is a sequencing task requiring children and adults to sort and sequence stimuli that are presented visually and auditorily. Validation data are presented for 268 participants ages 20 to 85 years. A subset of participants (N=89) was retested 7 to 21 days later. As expected, the List Sorting Test had moderately high correlations with other measures of working memory and executive functioning (convergent validity) but a low correlation with a test of receptive vocabulary (discriminant validity). Furthermore, List Sorting demonstrates expected changes over the age span and has excellent test-retest reliability. Collectively, these results provide initial support for the construct validity of the List Sorting Working Memory Measure as a measure of working memory. However, the relationship between the List Sorting Test and general executive function has yet to be determined.

    This article discusses about market segmentation and targeting as a first step in pre-test market of a new technology. The benefits of targeting towards pre-test market are pre-test market can be conducted to focus on selected target markets so there is no bias during the pre-test market. In determining the target market then do some surveys to identify the state of market in the future, so that the marketing process is not misplaced. Lithium ion battery which is commercialized through start-up companies is the case study. This start-up companies must be able to respond the changes and bring in customers as well as maintain them so that companies can survive and evolve to achieve its objectives. The research aims to determine market segments and target market effectively. Marketing strategy (segmentation and targeting) is used to make questionnaire and cluster analysis in data processing. Respondents were selected by purposive sampling and have obtained data as many as 80 samples. As the results study, there are three segments for lithium ion battery with their own distinguished characteristics and there are two segments that can be used as the target market for the company.

    An 80 V bipolar lead-acid battery was constructed and tested using hybrid electric vehicle (HEV) drive cycles. Drive cycles with a peak power of 6.7 kW, equal to 1/5 of the total power profile required for the HEV studied, were run successfully. Model calculations showed that the 80 V module constructed, which is at the moment 2.5 times heavier than required for the HEV operation studied, can be optimised to meet the requirements. (orig.)

    2016-04-01

    Full Text Available This paper outlines a study undertaken to determine if the electrical performance of Nickel Cobalt Aluminum Oxide (NCA 3.1 Ah 18650 battery cells can be degraded by road induced vibration typical of an electric vehicle (EV application. This study investigates if a particular cell orientation within the battery assembly can result in different levels of cell degradation. The 18650 cells were evaluated in accordance with Society of Automotive Engineers (SAE J2380 standard. This vibration test is synthesized to represent 100,000 miles of North American customer operation at the 90th percentile. This study identified that both the electrical performance and the mechanical properties of the NCA lithium-ion cells were relatively unaffected when exposed to vibration energy that is commensurate with a typical vehicle life. Minor changes observed in the cell’s electrical characteristics were deemed not to be statistically significant and more likely attributable to laboratory conditions during cell testing and storage. The same conclusion was found, irrespective of cell orientation during the test.

    Animal models for anxiety, depressive-like and cognitive diseases or aging often involve testing of subjects in behavioral test batteries. The large number of test variables with different mean variations and within and between test correlations often constitute a significant problem in determining essential variables to assess behavioral patterns and their variation in individual animals as well as appropriate statistical treatment. Therefore, we applied a multivariate approach (principal component analysis) to analyse the behavioral data of 162 male adult Sprague-Dawley rats that underwent a behavioral test battery including commonly used tests for spatial learning and memory (holeboard) and different behavioral patterns (open field, elevated plus maze, forced swim test) as well as for motor abilities (Rota rod). The high dimensional behavioral results were reduced to fewer components associated with spatial cognition, general activity, anxiety-, and depression-like behavior and motor ability. The loading scores of individual rats on these different components allow an assessment and the distribution of individual features in a population of animals. The reduced number of components can be used also for statistical calculations like appropriate sample sizes for valid discriminations between experimental groups, which otherwise have to be done on each variable. Because the animals were intact, untreated and experimentally naïve the results reflect trait patterns of behavior and thus individuality. The distribution of animals with high or low levels of anxiety, depressive-like behavior, general activity and cognitive features in a local population provides information of the probability of their appeareance in experimental samples and thus may help to avoid biases. However, such an analysis initially requires a large cohort of animals in order to gain a valid assessment.

    The present study investigated the effect of bilingualism on the two widely used developmental neuropsychological test batteries Wechsler Intelligence Scale for Children - Fourth Edition (WISC-IV) and A Developmental Neuropsychological Assessment, Second Edition (NEPSY-II) in children. The sample consisted of 100 Finland-Swedish children in two age groups. About half (n = 52) of the participants were early simultaneous bilinguals, and the other half (n = 48) were monolinguals. As no Finland-Swedish versions of the tests are available at the moment, both tests were translated and adapted to suit this population. The results revealed no difference in the performance between bilingual and monolingual children. This speaks against a cognitive advantage in bilingual children and indicates that development of separate norms for monolingual and bilingual children is not needed for clinical use.

    The Computer-Administered Neuropsychological Screen for Mild Cognitive Impairment (CANS-MCI), a computer administered, scored, and interpreted touch screen battery was evaluated for its ability to detect mild cognitive impairment. Subjects were three hundred ten community-dwelling elders who enrolled in an National Institute on Aging (NIA)-funded study. One-month test-retest reliability correlations were all significant (pWeschler Memory Scale-Revised (WMS-R) LMS-II test (ptests measure the intended cognitive dimensions of memory, language/spatial fluency, and executive function/mental control. Goodness-of-fit indicators were strong (Bentler Comparative Fit Index=0.99; Root Mean Square Error of Approximation=0.055). Initial validation analyses indicate that the CANS-MCI shows promise of being a reliable, valid screening tool in determining whether more intensive testing for early cognitive impairment is warranted.

    To optimise health for space missions, European astronauts follow specific conditioning programs before, during and after their flights. To evaluate the effectiveness of these programs, the European Space Agency conducts an Astronaut Fitness Assessment (AFA), but the test-retest reliability of elements within it remains unexamined. The reliability study described here presents a scientific basis for implementing the AFA, but also highlights challenges faced by operational teams supporting humans in such unique environments, especially with respect to health and fitness monitoring of crew members travelling not only into space, but also across the world. The AFA tests assessed parameters known to be affected by prolonged exposure to microgravity: aerobic capacity (VO2max), muscular strength (one repetition max, 1 RM) and power (vertical jumps), core stability, flexibility and balance. Intraclass correlation coefficients (ICC3.1), standard error of measurement and coefficient of variation were used to assess relative and absolute test-retest reliability. Squat and bench 1 RM (ICC3.1 = 0.94-0.99), hip flexion (ICC3.1 = 0.99) and left and right handgrip strength (ICC3.1 = 0.95 and 0.97), showed the highest test-retest reliability, followed by VO2max (ICC3.1 = 0.91), core strength (ICC3.1 = 0.78-0.89), hip extension (ICC3.1 = 0.63), the countermeasure (ICC3.1 = 0.76) and squat (ICC3.1 = 0.63) jumps, and single right- and left-leg jump height (ICC3.1 = 0.51 and 0.14). For balance, relative reliability ranged from ICC3.1 = 0.78 for path length (two legs, head tilted back, eyes open) to ICC3.1 = 0.04 for average rotation velocity (one leg, eyes closed). In a small sample (n = 8) of young, healthy individuals, the AFA battery of tests demonstrated acceptable test-retest reliability for most parameters except some balance and single-leg jump tasks. These findings suggest that, for the application with astronauts, most AFA tests appear appropriate to

    Efforts to achieve a 100 mile urban range, to reduce petroleum usage 40% to 70%, and to commercialize battery technology are discussed with emphasis on an all plastic body, four passenger car that is flywheel assisted and battery powered, and on an all metal body, four passenger car with front wheel drive and front motor. For the near term case, a parallel hybrid in which the electric motor and the internal combustion engine may directly power the drive wheels, is preferred to a series design. A five passenger car in which the electric motor and the gasoline engine both feed into the same transmission is discussed. Upgraded demonstration vehicles were tested using advanced lead acid, nickel zinc, nickel iron, and zinc chloride batteries to determine maximum acceleration, constant speed, and battery behavior. The near term batteries demonstrated significant improvement relative to current lead acid batteries. The increase in range was due to improved energy density, and ampere hour capacity, with relatively 1 small weight and volume differences.

    The goal of the present integrated project was to provide an innovative and integrative instrumentarium for assessing the quality of soils and soil substrates (contaminated and decontaminated soils). In addition to physicochemical methods this instrumentarium was also to make use of ecotoxicological tests, in pursuit of the dual goal of protecting human health and ecological soil functions. An essential prerequisite for this was the provision of a validated test battery for assessing soils and soil substrates. For this purpose ecotoxicological tests on soil eluates as well as terrestial tests were validated by means of ring tests. This was necessary because before this they were only standardised with respect to the effects of specific chemicals, not for use with soils and soil substrates. [German] Ziel des Verbundvorhabens ist die Bereitstellung eines integrativen innovativen Instrumentariums zur Bewertung der Qualitaet von Boeden und Bodensubstraten (belastete und gereinigte Boeden), das sich neben den chemisch-physikalischen Methoden auch auf oekotoxikologische Tests stuetzt, um neben dem Schutz der menschlichen Gesundheit auch das Ziel des Schutzes der oekologischen Bodenfunktionen realisieren zu koennen. Dazu bildet die Bereitstellung einer validierten ''Testbatterie'' zur Beurteilung von Boeden/Bodensubstraten die Voraussetzung. Daher werden oekotoxikologische Tests mit Bodeneluaten sowie terrestrische Tests, die zwar fuer die Erfassung von Wirkungen durch Chemikalien als Norm vorliegen, jedoch fuer die Testung von Boeden und Bodensubstraten noch validiert werden muessen, Ringtests unterworfen.

    Performing of the cycle testing according to the principles of Dynamic Stress Test can significantly reduce the overall time of development and production of batteries, which in turn allows reducing the cost of designing and testing of the spacecraft power systems. Performing of Dynamic Stress Test require special charge-discharge units that allows to perform a full cycle of electrical tests of batteries, including cyclic testing. Providing the required accuracy of measurement and stabilization of certain attributes of Li-ion battery operating modes is one of the problems that arise during thedevelopment of such charge-discharge units. The following attributes are of particular interest: charge and discharge currents, discharge powers, battery voltages. Analysis of the charge-discharge unit as a control system allows evaluating the steady-state stabilization error of the required attributes of the developed device. Moreover, using a digital integrator in the control system of the charge-discharge unit allows providing specified values of steady-state stabilization error of required attributes in different test modes.

    Full Text Available Background. The Psychology Experimental Building Language (PEBL test battery (http://pebl.sourceforge.net/ is a popular application for neurobehavioral investigations. This study evaluated the correspondence between the PEBL and the non-PEBL versions of four executive function tests. Methods. In one cohort, young-adults (N = 44 completed both the Conner’s Continuous Performance Test (CCPT and the PEBL CPT (PCPT with the order counter-balanced. In a second cohort, participants (N = 47 completed a non-computerized (Wechsler and a computerized (PEBL Digit Span (WDS or PDS both Forward and Backward. Participants also completed the Psychological Assessment Resources or the PEBL versions of the Iowa Gambling Task (PARIGT or PEBLIGT. Results. The between-test correlations were moderately high (reaction time r = 0.78, omission errors r = 0.65, commission errors r = 0.66 on the CPT. DS Forward was significantly greater than DS Backward on the WDS (p < .0005 and the PDS (p < .0005. The total WDS score was moderately correlated with the PDS (r = 0.56. The PARIGT and the PEBLIGTs showed a very similar pattern for response times across blocks, development of preference for Advantageous over Disadvantageous Decks, and Deck selections. However, the amount of money earned (score–loan was significantly higher in the PEBLIGT during the last Block. Conclusions. These findings are broadly supportive of the criterion validity of the PEBL measures of sustained attention, short-term memory, and decision making. Select differences between workalike versions of the same test highlight how detailed aspects of implementation may have more important consequences for computerized testing than has been previously acknowledged.

    A number of studies have investigated music perception in adult cochlear implant (CI) users. However, little is known about how pediatric CI users perceive and process music, in part because suitable methods for assessing music perception in this population are lacking. Therefore, we developed the Music in Children With Cochlear Implants (MCCI) battery to assess music perception in pediatric CI users younger than 9 years. To pilot test the MCCI on a group of pediatric CI users to determine its feasibility for measuring music perception and to compare performance of CI users with that of normal-hearing (NH) control participants. The pilot test was conducted in an academic tertiary care center. The MCCI evaluated rhythm, pitch, melody, harmony, and timbre perception. For each section, 10 pediatric CI users and 10 NH controls were presented with a pair of stimuli that possibly varied along a single musical element (eg, rhythm). Participants were required to indicate whether the stimuli in the pair were the same or different. Administration of the MCCI. Percentage correct on each section of the MCCI and the aggregate score of all sections by group. The MCCI provided a basic characterization of musical perceptual abilities. In the aggregate, NH controls significantly outperformed CI users in music perception (mean [SD] accuracy for CI users vs NH controls: rhythm, 73% [20%] vs 78% [20%]; pitch, 84% [12%] vs 91% [13%]; melody, 65% [16%] vs 75% [18%]; harmony, 74% [13%] vs 75% [14%]; and timbre, 80% [17%] vs 90% [12%]; repeated-measures analysis of variance, F1,17 = 9.3; P musical stimuli, although not to the extent of their NH peers. The MCCI provided an efficient and user-friendly assessment of music perception in pediatric CI users. This test battery may serve as a valuable tool to evaluate music perceptual abilities of pediatric CI users and measure the effects of interventions.

    2015-02-01

    Huntington's disease (HD) is a neurodegenerative genetic condition for which a predictive genetic test by mutation analysis has been available since 1993. However, whilst revealing the future presence of the disease, testing may have an adverse psychological impact given that the disease is progressive, incurable and ultimately fatal. This review seeks to systematically explore the psychological impact of genetic testing for individuals undergoing pre-symptomatic mutation analysis. Three databases (Medline, PsycInfo and Scopus) were interrogated for studies utilising standardised measures to assess psychological impact following predictive genetic testing for HD. From 100 papers initially identified, eight articles were eligible for inclusion. Psychological impact of predictive genetic testing was not found to be associated with test result. No detrimental effect of predictive genetic testing on non-carriers was found, although the process was not found to be psychologically neutral. Fluctuation in levels of distress was found over time for carriers and non-carriers alike. Methodological weaknesses of published literature were identified, notably the needs of individuals not requesting genetic testing, as well as inadequate support for individuals registering elevated distress and declining post-test follow-up. Further assessment of these vulnerable individuals is warranted to establish the extent and type of future psychological support.

    Full Text Available In this study, the micronuclei test (MNT was applied in exfoliated cells of buccal mucosa, in order to evaluate the genotoxic risk associated with occupational exposure of mechanics, storage battery renovation workers, and car painters. For each individual, 3000 exfoliated buccal cells were analyzed. There was a significantly higher frequency of micronucleated cells (MNC in the exposed workers than in controls. Smoking and drinking habits, age, and working time did not represent significant factors in terms of increasing the production of micronuclei (MN, when the control and the exposed groups were compared. These results allowed to conclude that the studied individuals belong to a risk group and should periodically undergo biological monitoring and proper care.

    Despite the importance of perceiving and recognizing facial expressions in everyday life, there is no comprehensive test battery for the multivariate assessment of these abilities. As a first step toward such a compilation, we present 16 tasks that measure the perception and recognition of facial emotion expressions, and data illustrating each task's difficulty and reliability. The scoring of these tasks focuses on either the speed or accuracy of performance. A sample of 269 healthy young adults completed all tasks. In general, accuracy and reaction time measures for emotion-general scores showed acceptable and high estimates of internal consistency and factor reliability. Emotion-specific scores yielded lower reliabilities, yet high enough to encourage further studies with such measures. Analyses of task difficulty revealed that all tasks are suitable for measuring emotion perception and emotion recognition related abilities in normal populations. PMID:24860528

    The present study summarises the work developed by the ALPHA (Assessing Levels of Physical Activity) study and describes the procedures followed to select the tests included in the ALPHA health-related fitness test battery for children and adolescents. The authors reviewed physical fitness and health in youth findings from cross-sectional studies. The authors also performed three systematic reviews dealing with (1) the predictive validity of health-related fitness, (2) the criterion validity of field-based fitness tests and (3) the reliability of field-based fitness tests in youth. The authors also carried out 11-methodological studies to determine the criterion validity and the reliability of several field-based fitness tests for youth. Finally, the authors performed a study in the school setting to examine the reliability, feasibility and safety of the selected tests. The selected fitness tests were (1) the 20 m shuttle run test to assess cardiorespiratory fitness; (2) the handgrip strength and (3) standing broad jump to assess musculoskeletal fitness, and (4) body mass index, (5) skinfold thickness and (5) waist circumference to assess body composition. When there are time limits, the authors propose the high-priority ALPHA health-related fitness test battery, which comprises all the evidence-based fitness tests except the measurement of the skinfold thickness. The time required to administer this battery to a group of 20 youth by one physical education teacher is less than 2 h. In conclusion, the ALPHA fitness tests battery is valid, reliable, feasible and safe for the assessment of health-related physical fitness in children and adolescents to be used for health monitoring purposes at population level.

    A high level of physical fitness is associated with cardiovascular health in children and adolescents. At present, there is no systematic implementation of a test battery to assess physical fitness at schools in Argentina. The main objective of this study was to implement the ALPHA test battery to determine the physical fitness of a sample made up of Argentine children and adolescents and to establish the proportion of subjects whose aerobic capacity is indicative of future cardiovascular risk. A sample of 1867 participants (967 girls) aged 6 to 19.5 years old assessed using the ALPHA test battery. Four components of physical fitness were measured: 1) morphological component: height, body weight, and waist circumference; 2) musculoskeletal component: standing long jump test; 3) motor component: speed/agility test (4x10 m shuttle run); 4) cardiorespiratory component: course-navette 20 m, shuttle run test and estimation of maximal oxygen consumption. The 5th, 25th, 50th, 75th, and 95th percentiles were estimated for the main tests. The mean body mass index was 20.8 kg/m2, and 7.8% of participants were classified as obese. In ddition, male participants had a better performance in all physical fitness tests when compared to girls (pfitness. Such differences increase with age. Approximately one every three participants had an aerobic capacity indicative of future cardiovascular risk.

    Full Text Available The lack of efficient animal models for bipolar disorder (BPD, especially for the manic pole, is a major factor hindering the research of its pathophysiology and the development of improved drug treatments. The present study was designed to identify an appropriate mouse strain for modeling some behavioral domains of mania and to evaluate the effects of drugs using this strain. The study compared the behavior of four strains: Black Swiss, C57Bl/6, CBA/J and A/J mice in a battery of tests that included spontaneous activity; sweet solution preference; light/dark box; resident-intruder; forced-swim and amphetamine-induced hyperactivity. Based on the ‘manic-like’ behavior demonstrated by the Black Swiss strain, the study evaluated the effects of the mood stabilizers valproate and lithium and of the antidepressant imipramine in the same tests using this strain. Results indicated that lithium and valproate attenuate the ‘manic-like’ behavior of Black Swiss mice whereas imipramine had no effects. These findings suggest that Black Swiss mice might be a good choice for modeling several domains of mania and distinguishing the effects of drugs on these specific domains. However, the relevance of the behavioral phenotype of Black Swiss mice to the biology of BPD is unknown at this time and future studies will investigate molecular differences between Black Swiss mice and other strains and asess the interaction between strain and mood stabilizing treatment.

    Electrochemical performance is often limited by surface and interfacial reactions at the electrodes. However, routine handling of samples can alter the very surfaces that are the object of study. Our approach combines standardized testing of batteries with sample harvesting under inert atmosphere conditions. Cells of different formats are disassembled inside an Argon glove box with controlled water and oxygen concentrations below 2 ppm. Cell components are characterized in situ, guaranteeing that observed changes in physicochemical state are due to electrochemical operation, rather than sample manipulation. We employ a complementary set of spectroscopic, microscopic, electrochemical and metallographic characterization to obtain a complete picture of cell degradation mechanisms. The resulting information about observed degradation mechanisms is provided to materials developers, both academic and industrial, to suggest new strategies and speed up the Research & Development cycle of Li-ion and related technologies. This talk will describe Argonne's post-test analysis laboratory, with an emphasis on capabilities and opportunities for collaboration. Cell disassembly, sample harvesting procedures and recent results will be discussed. This work was performed under the auspices of the U.S. Department of Energy, Office of Vehicle Technologies, Hybrid and Electric Systems, under Contract No. DE-AC02-06CH11357.

    Although sport for athletes with mental retardation (MR) is achieving an important role, literature concerning basketball test and training is still poor. The aims of this study were to assess basketball ability before (PRE) and after (POST) a 6-month training in athletes with MR across 2 sports seasons (ss) and to analyze the variation of basketball abilities by subjects' MR level. Fifteen trained basketball players with MR participated (11 men and 4 women; age range 19-43 years; MR: 3 Mild, 8 Moderate, 3 Severe, and 1 Profound). Athletes were tested PRE and POST a 6-month training during 2 following sports seasons (ss1 and ss2). The tests assessed 4 ability levels, each one characterized by the analysis of 4 fundamental areas (ball handling, reception, passing, and shooting), divided into 5 specific components. The athletes' global score improved after training in both ss1 (41.5 +/- 12.0 vs. 48.6 +/- 15.4; p < 0.01) and ss2 (41.7 +/- 12.4 vs. 50.8 +/- 16.2; p < 0.01). Levels II, III, and IV showed an increase both after each ss and the 2 following ss (p < 0.01). No significant difference was found between POST-ss1 and POST-ss2 due to score decrease during the resting period between the 2 ss. In both ss, global and level scores were negatively correlated to MR level indicating that athletes with a lower MR obtained higher ability scores. In conclusion, a 6-month training caused a general improvement, especially evident in levels II and III in both ss. Global and level scores were negatively correlated to MR level (p < 0.05) indicating that athletes with a lower MR obtained higher scores. Therefore, the basketball test battery could be useful for improving and monitoring training.

    Cognitive deficits in schizophrenia have major functional impacts. Modafinil is a cognitive enhancer whose effect in healthy volunteers is well-described, but whose effects on the cognitive deficits of schizophrenia appear to be inconsistent. Two possible reasons for this are that cognitive test batteries vary in their sensitivity, or that the phase of illness may be important, with patients early in their illness responding better. A double-blind, randomised, placebo-controlled single-dose crossover study of modafinil 200 mg examined this with two cognitive batteries [MATRICS Consensus Cognitive Battery (MCCB) and Cambridge Neuropsychological Test Automated Battery (CANTAB)] in 46 participants with under 3 years' duration of DSM-IV schizophrenia, on stable antipsychotic medication. In parallel, the same design was used in 28 age-, sex-, and education-matched healthy volunteers. Uncorrected p values were calculated using mixed effects models. In patients, modafinil significantly improved CANTAB Paired Associate Learning, non-significantly improved efficiency and significantly slowed performance of the CANTAB Stockings of Cambridge spatial planning task. There was no significant effect on any MCCB domain. In healthy volunteers, modafinil significantly increased CANTAB Rapid Visual Processing, Intra-Extra Dimensional Set Shifting and verbal recall accuracy, and MCCB social cognition performance. The only significant differences between groups were in MCCB visual learning. As in earlier chronic schizophrenia studies, modafinil failed to produce changes in cognition in early psychosis as measured by MCCB. CANTAB proved more sensitive to the effects of modafinil in participants with early schizophrenia and in healthy volunteers. This confirms the importance of selecting the appropriate test battery in treatment studies of cognition in schizophrenia.

    Full Text Available According to Kerchoffs (1883, the security system should only rely on cryptographic keys which is used in that system. Generally, the key sequences are generated by a Pseudo Random Number Generator (PRNG or Random Number Generator (RNG. There are three types of randomness sequences that generated by the RNG and PRNG i.e. pseudorandom sequence, cryptographically secure pseudorandom sequences, and real random sequences. Several statistical tests, including diehard battery of tests of randomness, is used to check the type of randomness sequences that generated by PRNG or RNG. Due to its purpose, the principle on taking the testing parameters and the test statistic are associated with the validity of the conclusion produced by a statistical test, then the theoretical analysis is performed by applying a variety of statistical theory to evaluate craps test, one of the test included in the diehard battery of randomness tests. Craps test, inspired by craps game, aims to examine whether a PRNG produces an independent and identically distributed (iid pseudorandom sequences. To demonstrate the process to produce a test statistics equation and to show how craps games applied on that test, will be carried out theoretical analysis by applying a variety of statistical theory. Furthermore, empirical observations will be done by applying craps test on a PRNG in order to check the test effectiveness in detecting the distribution and independency of sequences which produced by PRNG

  13. Old world monkeys compare to apes in the primate cognition test battery.

    Directory of Open Access Journals (Sweden)

    Vanessa Schmitt

    Full Text Available Understanding the evolution of intelligence rests on comparative analyses of brain sizes as well as the assessment of cognitive skills of different species in relation to potential selective pressures such as environmental conditions and social organization. Because of the strong interest in human cognition, much previous work has focused on the comparison of the cognitive skills of human toddlers to those of our closest living relatives, i.e. apes. Such analyses revealed that apes and children have relatively similar competencies in the physical domain, while human children excel in the socio-cognitive domain; in particular in terms of attention sharing, cooperation, and mental state attribution. To develop a full understanding of the evolutionary dynamics of primate intelligence, however, comparative data for monkeys are needed. We tested 18 Old World monkeys (long-tailed macaques and olive baboons in the so-called Primate Cognition Test Battery (PCTB (Herrmann et al. 2007, Science. Surprisingly, our tests revealed largely comparable results between Old World monkeys and the Great apes. Single comparisons showed that chimpanzees performed only better than the macaques in experiments on spatial understanding and tool use, but in none of the socio-cognitive tasks. These results question the clear-cut relationship between cognitive performance and brain size and--prima facie--support the view of an accelerated evolution of social intelligence in humans. One limitation, however, is that the initial experiments were devised to tap into human specific skills in the first place, thus potentially underestimating both true nonhuman primate competencies as well as species differences.

    Full Text Available After a brief introduction the theoretical basis of the Munich High Ability Test-Battery (MHBT will be outlined in the first part of the article. The MHBT has been developed in the framework of the Munich longitudinal study of giftedness and talent. The MHBT includes not only cognitive predictors measuring several dimensions and types of giftedness concerning intellectual, creative or social abilities etc., but also giftedness-relevant non-cognitive personality and social moderators measuring interests, motivations, learning emotions, self-concepts or family and school climate, educational style, quality of instruction, etc. The MHBT-instruments (different scales and dimensions are described in greater detail.In the second part of the article, after dealing with the objectivity, the reliability, and the validity of the MHBT, the authors discuss the standardization procedure including the development of grade-based T-norms respectively as well as several talent-profiles, e.g. of gifted achievers vs. underachievers, intellectual, creative, social talents or linguistic, math, science talent profiles etc. Finally, examples of talent search for gifted programs and case studies on the basis of MHBT should illustrate multidimensional identification procedures.The MHBT fulfills the most relevant assessment tasks belonging to the gifted educational and counseling practice. The usefulness of the MHBT in the framework of giftedness research as well as of gifted program evaluation studies has also been proven in the last decade. Hence the MHBT offers many opportunities to assessing giftedness and talent.

    Cognitive evaluation of young subjects is now widely carried out for non-traumatic diseases such as multiple sclerosis, HIV, or sleep disorders. This evaluation requires normative data based on healthy adult samples. However, most clinicians use a set of tests that were normed in an isolated manner from different samples using different cutoff criteria. Thus, the score of an individual may be considered either normal or impaired according to the norms used. It is well established that healthy adults obtained low-test scores when a battery of tests is administered. Thus, the knowledge of low base rates is required so as to minimize false diagnosis of cognitive impairment. The aim of this study was twofold (1) to provide normative data for RAPID-II battery in healthy adults, and (2) estimate the proportion of healthy adults having low scores across this battery. Norms for the 44 test scores of the RAPID-II test battery were developed using the overall sample of 335 individuals based on three categories of age (20 to 29, 30 to 39, and 40 to 49 years) and two educational levels: Baccalaureate or higher educational degree (high educational level), lower than baccalaureate (low educational level). The 5th, 25th, 50th, and 75th percentiles were calculated from the six age and education subsamples and used to define norms. The frequency of low scores on the RAPID-II battery was calculated by simultaneously examining the performance of 33 primary scores. A low score was defined as less than or equal to the 5th percentile drawn from the six age and education normative subsamples. In addition, the percentages of low scores were also determined when all possible combinations of two-test scores across the RAPID-II were considered in the overall normative sample. Our data showed that 59.4% subjects of the normative sample obtained at least one or more low score. With more than 9 test scores, this percentage was equal to 0% in the normative sample. Among all combinations of two-test

    The Nine Plus screening battery test (9+) is a functional movement test intended to identify limitations in fundamental movement patterns predisposing athletes to injury. However, the interseason variability is unknown. To examine the variability of the 9+ test between 2 consecutive seasons in professional male football players. Asymptomatic Qatar Star League players (n=220) completed the 9+ at the beginning of the 2013 and 2014 seasons. Time-loss injuries in training and matches were obtained from the Aspetar Injury and Illness Surveillance Program. No intervention was initiated between test occasions. A significant increase in the mean total score of 1.6 points (95% CI 1.0 to 2.2, p<0.001) was found from season 1 (22.2±4.1 (SD)) to season 2 (23.8±3.3). The variability was large, as shown by an intraclass correlation coefficient (ICC) of 0.24 (95% CI 0.11 to 0.36) and a minimal detectable change (MDC) of 8.7 points. Of the 220 players, 136 (61.8%) suffered a time-loss injury between the 2 tests. There was an improvement in mean total scores in the injured (+2.0±0.4 (SE), p<0.001) group but not in the uninjured group (+0.9±0.5, p=0.089). The variability from season 1 to season 2 was large both in the injured (ICC 0.25, 0.09 to 0.40, MDC 8.3) and uninjured (ICC 0.24, 0.02 to 0.43, MDC 9.1) groups. The 9+ demonstrated substantial intraindividual variability in the total score between 2 consecutive seasons, irrespective of injury. A change above 8 points is necessary to represent a real change in the 9+ test between seasons. Published by the BMJ Publishing Group Limited.

    The reasons why some patients who begin the presurgical process for bariatric surgery fail to complete the procedure are understudied. Previous research implies that psychological factors play a role. To examine whether scores from baseline psychological testing incrementally predict failure to proceed with bariatric surgery beyond demographic information in patients' medical charts and data derived from a clinical interview. Cleveland Clinic Bariatric and Metabolic Institute. The sample (n = 1160) was mainly female (72.41%), middle aged (mean age = 46.07 yr, SD = 11.70) and of Caucasian descent (65.76%). Hierarchical logistic regressions were conducted to test the incremental validity of baseline Minnesota Multiphasic Personality Inventory-2 Restructured Form scores after controlling for information gathered from the psychological interview and medical charts. Relative risk ratios were calculated to reflect the clinical utility of the results. In total, 27.16% of patients failed to proceed with bariatric surgery after 1 year or more after a recommendation for surgery from their psychological evaluations. Psychological test scores were substantially associated with failure to proceed with surgery and significantly accounted for up to 6% of additional variance after controlling for psychological interview variables and medical chart data. Elevated scores on Minnesota Multiphasic Personality Inventory-2 Restructured Form scales, such as anxiety and substance use, identify patients at up to 2.5 times greater risk for failing to proceed with bariatric surgery. Objective psychological test data-notably, scale scores assessing for substance abuse, anxiety, and demoralization-add to information obtained from a clinical interview and medical records in identifying patients at risk for failing to proceed with bariatric surgery.

    Standardised neuropsychological and cognitive measures present some limitations in their applicability and generalisability to individuals with intellectual disability (ID). Alternative approaches to defining the cognitive signatures of various forms of ID are needed to advance our understanding of the profiles of strengths and weaknesses as well as the affected brain areas. To evaluate the utility and feasibility of six non-verbal comparative neuropsychological (CN) tasks administered in a modified version of the Wisconsin General Test Apparatus (WGTA) to confirm and extend our knowledge of unique cognitive signatures of Fragile X syndrome (FXS) and Down syndrome (DS). A test battery of CN tasks adapted from the animal literature was administered in a modified WGTA. Tasks were selected that have established or emerging brain-behaviour relationships in the domains of visual-perceptual, visual-spatial, working memory and inhibition. Despite the fact that these tasks revealed cognitive signatures for the two ID groups, only some hypotheses were supported. Results suggest that whereas individuals with DS were relatively impaired on visual-perceptual and visual-spatial reversal learning tasks they showed strengths in egocentric spatial learning and object discrimination tasks. Individuals with FXS were relatively impaired on object discrimination learning and reversal tasks, which was attributable to side preferences. In contrast, these same individuals exhibited strengths in egocentric spatial learning and reversal tasks as well as on an object recognition memory task. Both ID groups demonstrated relatively poor performance for a visual-spatial working memory task. Performance on the modified WGTA tasks differentiated cognitive signatures between two of the most common forms of ID. Results are discussed in the context of the literature on the cognitive and neurobiological features of FXS and DS.

    To investigate the effects of different tilt angles of head-up tilt test (HUTT) and different responses to HUTT on the psychological fear in children undergoing the test. HUTT was performed on children with unexplained syncope or pre-syncope (107 cases: 52 males and 55 females), aged 5.5-17.8 years (mean 12.0±2.8 years). All subjects were randomly assigned to undergo HUTT at an angle of 60°, 70° or 80°; the negative cases underwent sublingual nitroglycerin-provocation HUTT at the same tilt angle. The Wong-Baker Faces Pain Rating Scale was used for self-assessment of psychological fear in subjects during HUTT at the end point of the test. The positive rate, hemodynamic changes and distribution of response types showed no significant differences between children at tilt angles of 60°, 70° and 80° (P>0.05). The greater the tilt angle, the higher the degree of psychological fear in children undergoing the test, but there were no significant differences between them (P>0.05). The degree of psychological fear in children who showed a positive response to HUTT (n=76) was significantly higher than that in children who showed a negative response (n=31) (Ppsychological fear in children undergoing the test, and the degree of psychological fear increases in children tested at tilt angles from 60° to 80°, but the differences have no statistical significance. A positive response to HUTT can significantly increase the psychological fear in children.

    A European round robin test according to ISO 5725-2 was conceptually prepared, realised, and evaluated. The aim was to determine the inter-laboratory variability of the overall process for the ecotoxicological characterization of construction products in eluates and bioassays. To this end, two construction products BAM-G1 (granulate) and HSR-2 (roof sealing sheet), both made of EPDM polymers (rubber), were selected. The granular construction product was eluted in a one stage batch test, the planar product in the Dynamic Surface Leaching test (DSLT). A total of 17 laboratories from 5 countries participated in the round robin test: Germany (12), Austria (2), Belgium (1), Czech Republic (1) and France (1). A test battery of four standardised ecotoxicity tests with algae, daphnia, luminescent bacteria and zebrafish eggs was used. As toxicity measures, EC50 and LID values were calculated. All tests, except the fish egg test, were basically able to demonstrate toxic effects and the level of toxicity. The reproducibility of test results depended on the test specimens and the test organisms. Generally, the variability of the EC50 or LID values increased with the overall level of toxicity. For the very toxic BAM-G1 eluate a relative high variability of CV = 73%-110% was observed for EC50 in all biotests, while for the less toxic HSR-2 eluate the reproducibility of EC50 varied with sensitivity: it was very good (CV = 9.3%) for the daphnia test with the lowest sensitivity, followed by the algae test (CV = 36.4%). The luminescent bacteria test, being the most sensitive bioassay for HSR-2 Eluate, showed the highest variability (CV = 74.8%). When considering the complex overall process the reproducibility of bioassays with eluates from construction products was acceptable. Copyright © 2017. Published by Elsevier Ltd.

    Serotonin-norepinephrine reuptake inhibitors inhibit the reuptake of serotonin and noradrenalin and are used in the treatment of neuropathic pain. Animal studies suggest that milnacipran co-administered with opioids may potentiate the analgesic effect of μ-opioid receptor agonists. This study hypothesized that co-administration of milnacipran and buprenorphine would have a synergistic effect in evoked pain models in healthy subjects. This was a randomized double-blinded, placebo-controlled, four-way cross-over, multiple dose clinical trial to investigate the analgesic effects of buprenorphine (placebo, 0.5, 1 and 3 μg/kg) in combination with milnacipran (placebo, 25 and 50 mg) in healthy subjects. 11 healthy men were enrolled in the study. Buprenorphine alone showed a dose-response relationship indicative of anti-nociception in the pain tests. Following milnacipran administration, no changes were seen in the pharmacodynamic measurements for pain, psychomotor function, body stability or eye movements. For the electrical tests, cold pressor test and pressure pain test, buprenorphine alone was superior when compared with buprenorphine plus milnacipran. No differences in pharmacodynamic variables, besides an increase in pupil/iris ratio, were observed after repeated administration of milnacipran 50 mg. Single and multiple doses of 25 or 50 mg milnacipran did not further potentiate the anti-nociceptive effects of buprenorphine. Buprenorphine showed dose-dependent effects consistent with its pharmacological profile. Milnacipran alone did not affect any of the pain variables. The combination of both buprenorphine and milnacipran did not potentiate or show a synergistic effect on the pain models used in this study. Buprenorphine is known to be a potent opioid agonist. Animal studies suggest that milnacipran co-administered with opioids may potentiate the analgesic effect of μ-opioid receptor agonists. Here, we found that buprenorphine showed a dose

    Test Reviews in Child Psychology: Test Users Wish to Obtain Practical Information Relevant to their Respective Field of Work This study investigated to what extent diagnosticians use reviews of psychometric tests for children and adolescents, how they evaluate their quality, and what they expect concerning content. Test users (n = 323) from different areas of work (notably social pediatrics, early intervention, special education, speech and language therapy) rated test reviews as one of the most important sources of information. Readers of test reviews value practically oriented descriptions and evaluations of tests that are relevant to their respective field of work. They expect independent reviews that critically discuss opportunities and limits of the tests under scrutiny. The results show that authors of test reviews should not only have a background in test theory but should also be familiar with the practical application of tests in various settings.

  11. Ethnic identity, identity coherence, and psychological functioning: testing basic assumptions of the developmental model.

    2014-04-01

    The purpose of the present study was to test three fundamental theoretical propositions from Phinney's (1990) developmental model about the relations among ethnic identity, identity coherence, and psychological functioning: (a) ethnic identity is more strongly related to identity coherence for ethnic minorities than for Whites; (b) ethnic identity is more strongly related to psychological functioning for ethnic minorities than for Whites; and (c) identity coherence mediates the association between ethnic identity and psychological functioning for ethnic minorities, but not for Whites. These hypotheses were tested in three independent samples of ethnically diverse youth. In general, we found weak to moderate support for these three hypotheses, suggesting that the theoretically proposed differences in ethnic identity between ethnic minorities and Whites may not be supported by data. Implications for theory and measurement of ethnic identity are discussed.

    Executive function (EF) is an important predictor of numerous developmental outcomes, such as academic achievement and behavioral adjustment. Although a plethora of measurement instruments exists to assess executive function in children, only few of these are suitable for toddlers, and even fewer have undergone psychometric evaluation. The present study evaluates the psychometric properties and validity of an assessment battery for measuring EF in two-year-olds. A sample of 2437 children were administered the assessment battery at a mean age of 2;4 years (SD = 0;3 years) in a large-scale field study. Measures of both hot EF (snack and gift delay tasks) and cool EF (six boxes, memory for location, and visual search task) were included. Confirmatory Factor Analyses showed that a two-factor hot and cool EF model fitted the data better than a one-factor model. Measurement invariance was supported across groups differing in age, gender, socioeconomic status (SES), home language, and test setting. Criterion and convergent validity were evaluated by examining relationships between EF and age, gender, SES, home language, and parent and teacher reports of children's attention and inhibitory control. Predictive validity of the test battery was investigated by regressing children's pre-academic skills and behavioral problems at age three on the latent hot and cool EF factors at age 2 years. The test battery showed satisfactory psychometric quality and criterion, convergent, and predictive validity. Whereas cool EF predicted both pre-academic skills and behavior problems 1 year later, hot EF predicted behavior problems only. These results show that EF can be assessed with psychometrically sound instruments in children as young as 2 years, and that EF tasks can be reliably applied in large scale field research. The current instruments offer new opportunities for investigating EF in early childhood, and for evaluating interventions targeted at improving EF from a young age.

    Full Text Available Executive function (EF is an important predictor of numerous developmental outcomes, such as academic achievement and behavioral adjustment. Although a plethora of measurement instruments exists to assess executive function in children, only few of these are suitable for toddlers, and even fewer have undergone psychometric evaluation. The present study evaluates the psychometric properties and validity of an assessment battery for measuring EF in two-year-olds. A sample of 2437 children were administered the assessment battery at a mean age of 2;4 years (SD = 0;3 years in a large-scale field study. Measures of both hot EF (snack and gift delay tasks and cool EF (six boxes, memory for location, and visual search task were included. Confirmatory Factor Analyses showed that a two-factor hot and cool EF model fitted the data better than a one-factor model. Measurement invariance was supported across groups differing in age, gender, socioeconomic status (SES, home language, and test setting. Criterion and convergent validity were evaluated by examining relationships between EF and age, gender, SES, home language, and parent and teacher reports of children’s attention and inhibitory control. Predictive validity of the test battery was investigated by regressing children’s pre-academic skills and behavioral problems at age three on the latent hot and cool EF factors at age two years. The test battery showed satisfactory psychometric quality and criterion, convergent, and predictive validity. Whereas cool EF predicted both pre-academic skills and behavior problems one year later, hot EF predicted behavior problems only. These results show that EF can be assessed with psychometrically sound instruments in children as young as two years, and that EF tasks can be reliably applied in large scale field research.

  14. Normative comparisons for large neuropsychological test batteries: User-friendly and sensitive solutions to minimize familywise false positives.

    In neuropsychological research and clinical practice, a large battery of tests is often administered to determine whether an individual deviates from the norm. We formulate three criteria for such large battery normative comparisons. First, familywise false-positive error rate (i.e., the complement of specificity) should be controlled at, or below, a prespecified level. Second, sensitivity to detect genuine deviations from the norm should be high. Third, the comparisons should be easy enough for routine application, not only in research, but also in clinical practice. Here we show that these criteria are satisfied for current procedures used to assess an overall deviation from the norm-that is, a deviation given all test results. However, we also show that these criteria are not satisfied for current procedures used to assess test-specific deviations, which are required, for example, to investigate dissociations in a test profile. We therefore propose several new procedures to assess such test-specific deviations. These new procedures are expected to satisfy all three criteria. In Monte Carlo simulations and in an applied example pertaining to Parkinson disease, we compare current procedures to assess test-specific deviations (uncorrected and Bonferroni normative comparisons) to new procedures (Holm, one-step resampling, and step-down resampling normative comparisons). The new procedures are shown to: (a) control familywise false-positive error rate, whereas uncorrected comparisons do not; (b) have higher sensitivity than Bonferroni corrected comparisons, where especially step-down resampling is favorable in this respect; (c) be user-friendly as they are implemented in a user-friendly normative comparisons website, and as the required normative data are provided by a database. These new normative comparisons procedures, especially step-down resampling, are valuable additional tools to assess test-specific deviations from the norm in large test batteries.

    For electrically powered applications such as consumer electronics and especially for electric vehicles a precise state-of-charge estimation for their lithium-ion batteries is desired to reduce aging, e.g. avoiding detrimental states-of-charge. Today, this estimation is performed by battery management systems that solely rely on charge bookkeeping and cell voltage measurements. In the present work we introduce a new, physical probe for the state-of-charge based on ultrasonic transmission. Within the simple experimental setup raised cosine pulses are applied to lithium-ion battery pouch cells, whose signals are sensitive to changes in porosity of the graphite anode during charging/dis-charging and, therefore, to the state-of-charge. The underlying physical principle can be related to Biot's theory about propagation of waves in fluid saturated porous media and by including scattering by boundary layers inside the cell.

    In seeking to understand how life-threatening illness affects children psychologically, projective testing may be beneficial, particularly when attempting to identify psychological problems in younger adolescents. The advantages of projective testing are that it does not depend on patients' verbal ability and is not invasive. Three cancer inpatients from Kyoto Prefectural University of Medicine, aged between 10 and 16 years old, participated in the study. Projective testing was used to measure the depth of participants' distress and included a tree-drawing test, a person-drawing test and a free drawing test. Results from the tree- and person-drawing tests indicated energy loss, anxiety and a sense of emptiness. However, results from the free drawing test suggested that the children had hope and a desire to recover from their illness. The combination of drawing tests in this study may increase the understanding of the internal psychological difficulties faced by children hospitalized with cancer. © The Author 2014.

    Nonlinguistic cognitive impairment has become an important issue for aphasic patients, but currently there are few neuropsychological cognitive assessment tests for it. To get more information on cognitive impairment of aphasic patients, this study aimed to develop a new cognitive assessment test battery for aphasic patients, the Non-language-based Cognitive Assessment (NLCA), and evaluate its utility in Chinese-speaking patients with aphasia. The NLCA consists of five nonverbal tests, which could assess five nonlinguistic cognitive domains such as visuospatial functions, attention test, memory, reasoning, and executive functions of aphasic patients. All tests are modified from the nonverbal items of the current existed tests with some changes to the characteristics of Chinese culture. The NLCA was tested in 157 participants (including 57 aphasic patients, 50 mild cognitive impairment (MCI) patients, and 50 normal controls), and was compared with other well-established relative neuropsychological tests on the reliability, validity, and utility. The NLCA was fully applicable in the MCI patients and the normal controls, almost working in the aphasic patients (57/62 patients, 91.9%). The NLCA scores were 66.70 ± 6.30, 48.67 ± 15.04, and 77.58 ± 2.56 for the MCI group, the aphasic group, and the control group, respectively , and a significant difference was found among three groups (F = 118.446, P battery to specially find nonlinguistic cognitive function for aphasic patients.

    To determine the implicit or unconscious attitudes of Nursing and Psychology majors towards overweight individuals in medical and non-medical contexts. Obesity is a leading health concern today, which impacts both physical and psychological health. Overweight individuals confront social biases in many aspects of their lives including health care. Examining the views of Nursing and Psychology students may reveal implicit attitudes towards overweight individuals that may lead to prejudiced behaviours. A mixed design experiment with one between-subjects variable (student major: Nursing or Psychology) and one within-subjects variable (condition: congruent or incongruent) was used to assess implicit attitudes in two convenience samples of Nursing and Psychology students. A computerised implicit association test was used to determine implicit attitudes towards overweight individuals in medical and non-medical contexts. A total of 90 students from Nursing (n= 45) and Psychology (n = 45) were recruited to complete an implicit association test. Reaction times in milliseconds between the congruent trials (stereotype consistent) and incongruent trials (stereotype inconsistent) were compared with determine adherence to social stereotypes or weight bias. A statistically significant implicit bias towards overweight individuals was detected in both subject groups and in both target settings (medical vs. non-medical). Stronger weight bias was found when the stimulus targets were female than male. Findings from this study expand understanding of the implicit attitudes and social biases of Nursing and Psychology students. The views held by these future healthcare professionals may negatively impact patient care. Providing education and support to overweight individuals is central to Nursing practice in a society struggling to manage obesity. Negative stereotypes or beliefs about these individuals may result in poor patient care. Therefore, nurses and other healthcare professionals

    The present study aimed to provide normative data on a large sample of the elderly Italian population (N = 464; range of age = 49-94; range of education = 3-25) on both the word and the picture versions of a battery of free recall, cued recall, and recognition tests of memory. Results from multiple regression analyses showed that both age and education were significant predictors of performance. Therefore, norms were calculated taking into account these demographic variables. The availability of normative data based on a large sample will allow a more reliable use of the battery for clinical assessment in Italian-speaking dementia population.

    The purpose of the current study is to evaluate the validity and reliability of the revised Gibson Test of Cognitive Skills, a computer-based battery of tests measuring short-term memory, long-term memory, processing speed, logic and reasoning, visual processing, as well as auditory processing and word attack skills. This study included 2,737 participants aged 5-85 years. A series of studies was conducted to examine the validity and reliability using the test performance of the entire norming group and several subgroups. The evaluation of the technical properties of the test battery included content validation by subject matter experts, item analysis and coefficient alpha, test-retest reliability, split-half reliability, and analysis of concurrent validity with the Woodcock Johnson III Tests of Cognitive Abilities and Tests of Achievement. Results indicated strong sources of evidence of validity and reliability for the test, including internal consistency reliability coefficients ranging from 0.87 to 0.98, test-retest reliability coefficients ranging from 0.69 to 0.91, split-half reliability coefficients ranging from 0.87 to 0.91, and concurrent validity coefficients ranging from 0.53 to 0.93. The Gibson Test of Cognitive Skills-2 is a reliable and valid tool for assessing cognition in the general population across the lifespan.

    The purposes of this study were (1) to develop a battery of tests that assessed a wide range of functional abilities relevant to driving yet could be performed in a clinician's office and (2) to determine which of these tests were most closely associated with self-reported adverse driving events. A cohort study. An urban community. Participants were drawn from the Project Safety cohort, a probability sample of noninstitutionalized older persons in New Haven, Connecticut, initiated in 1989. The current study included surviving, active drivers in the cohort (N=125). The test battery assessed visual, cognitive, and physical abilities potentially relevant to driving, and was administered in participants' homes by trained interviewers between October 1994 and July 1995. Outcome measures included the self-report of a crash, moving violation, or being stopped by police in any Project Safety interview since the inception of the cohort. Analyses compared performance on the elements of the test battery with participants' histories of adverse driving events. Of the 125 drivers, 50 (40%) had reported an adverse event in a mean period of 5.76 (+/-.25) years before the current interview. The elements of the test battery independently associated with a history of events, adjusting for driving frequency, included near visual acuity worse than 20/40 (adjusted odds ratio 11.90), limited neck rotation (OR 6.10), and poor performance on a test of visual attention, the number cancellation task (OR 3.00). The resulting regression equation yielded a sensitivity of 80%, a specificity of 55%, and an area under the curve of .75 by receiver operating characteristic analysis. These findings suggest it may be possible to identify individuals potentially at risk for self-reported adverse driving events using simple tests of functional ability. If validated, such an approach could be used to identify individuals who need a more detailed assessment of functional abilities to determine the

    The development of fuel cells for traction accelerated the last years because of severe emission demands for road vehicles. Because of these rapid developments a commercial application in 5 to 10 years is feasible which means that the fuel cell can be used for the generation of electric energy on board naval ships currently being developed. In the application of fuel cells and the integration in a ship`s system, the combination with a battery is important. To get insight into the possible problems involved, TNO has carried out orientating tests with a fuel cell/battery combination. The report describes the results. The tests carried out are related to charging of the battery with the fuel cell (at various initial states of charge of the battery) and taking a continuously increasing power out of the fuel cell/battery combination. No tests with a DC/DC converter have been carried out so far, because battery and fuel cell voltage were adapted to each other and because of the orientating character of the study. The tests show that this is possible without any problems. However, in practice, DC/DC converters will generally be required for various reasons. Therefore further development and testing of this combination, including DC/DC converters, control equipment etc. is advised.

    This article examines a case of intelligence testing conducted in the mid-1920s, while considering the broader political and scientific context of Soviet life. Guided by questions about the status and influence of mental measurement in Russian society, previously and after the revolution, as well as asking about the main actors in the fields linked to testing, such as psychology, pedagogy, and pedology, during this tumultuous period. To answer these questions, journals and difficult-to-access archival sources were used, which provided evidence regarding the enthusiasm psychological testing had on scholars in the 1920s and the institutional support they received for their surveys. The article offers some hints concerning why this was so and why this situation changed completely a decade later. (PsycINFO Database Record (c) 2014 APA, all rights reserved).

    To assess the within-day inter-rater reliability of a test battery of functional performance, muscle strength and leg extension power on total hip replacement patients. A test-retest design was used. Orthopaedic department at a Regional Hospital in Denmark. Two convenience samples of 20 total hip replacement patients were included. The tests were performed three months after total hip replacement. Two raters performed test and re-test, with two hours rest in-between. The test battery included: sit-to-stand performance, 20-metre maximum walking speed, stair climb performance, isometric muscle strength (hip abduction/flexion), and leg extension power. Absolute reliability was assessed with Bland Altman plots, standard error of measurement (SEM), and minimal detectable change. Relative reliability was assessed with intra-class correlation coefficient. Systematic differences between testers were seen in tests of walking speed (0.32 seconds p = 0.03) and stair climb performance (0.18 seconds p = 0.003). In per cent of the grand mean, the standard error of measurement was 3%-10%, indicating the measurement error on a group level, and the minimal detectable change was 10%-27%, indicating the measurement error on an individual level. The intra-class correlation coefficients were above 0.80 in all tests (range 0.83-0.95). The tests showed acceptable relative and absolute inter-rater reliability on a group level, but not on an individual level (except from test of walking speed and stair climb performance). Systematic differences between testers were considered clinically irrelevant (0.3 and 0.2 seconds). © The Author(s) 2014.

    Gymnastics talent identification focuses on the identification of young gymnasts who display characteristics for potential success in the future. The aim of this study was to identify which current performance characteristics are related to performance in competition 2 years later. Twenty-three female gymnasts aged 7-8 years completed a multidimensional test battery measuring anthropometric, physical, and coordinative characteristics and were technically evaluated by expert coaches. Two years later, the all-around competition results of those gymnasts now participating in elite (n = 12) and sub-elite (n = 11) competition were obtained. None of the initial measurements significantly correlated with the results of the sub-elite gymnasts 2 years later. For the elite gymnasts, a non-sport-specific motor test battery correlated strongly with the competition result, with more than 40% of the variation in competition performance being explained by the result on that test 2 years earlier. Neither the coaches' judgement nor the anthropometric and physical characteristics were sensitive enough to predict performance. A motor coordination test might be valuable in the early identification of gymnasts, as its discriminative and predictive qualities might be sufficiently powerful for selection within a relatively homogeneous population of gymnasts exhibiting similar anthropometric and physical profiles.

  18. The Language Research Center's Computerized Test System for environmental enrichment and psychological assessment

    1992-01-01

    In the spring of 1987, we undertook to provide environmental enrichment to nonhuman primate subjects in ways that would complement and even contribute to the bio-behaviorial science that justified the monkeys' captivity. Of course, the psychological well-being of captive primates--and indeed all research species-- has been an area of intense research activity since the 1985 amendment of the Animal Welfare Act. This mandate for researchers to ensure the psychological, as well as physical, fitness of experimental animals catalyzed the humane and scientific interests of the research community. The contemporary literature is replete with proposed means both of assaying and of providing enrichment and well-being. Notwithstanding, consensus on either assessment or intervention has yet to be reached. The paradigm we employed was modelled after successful efforts with chimpanzees. An automated test system was constructed in which subjects responded to computer tasks by manipulating a joystick. The tasks, interactive game-like versions of many of the classic testing paradigms of cognitive and comparative psychology, permitted the controlled presentation of stimuli and demands without the required presence of a human experimenter. Despite significant barriers to the success, rhesus monkeys (Macaca mulatta) and a variety of other primate species (including, of course, humans) have mastered the skills necessary for testing in this paradigm. Previous experiments have illustrated the utility of the test system for addressing questions of learning, memory, attention, perception, and motivation. Additional data have been reported to support the contention that the Language Research Center's Computerized Test System (LRC-CTS) serves its other raison d'etre--providing environmental enrichment and assessing psychological well-being. This paper is designed to augment previous descriptions of the technology and the paradigm for scientists and caretakers interested in environmental

    Norm statistics allow for the interpretation of scores on psychological and educational tests, by relating the test score of an individual test taker to the test scores of individuals belonging to the same gender, age, or education groups, et cetera. Given the uncertainty due to sampling error, one would expect researchers to report standard errors for norm statistics. In practice, standard errors are seldom reported; they are either unavailable or derived under strong distributional assumptions that may not be realistic for test scores. We derived standard errors for four norm statistics (standard deviation, percentile ranks, stanine boundaries and Z-scores) under the mild assumption that the test scores are multinomially distributed. A simulation study showed that the standard errors were unbiased and that corresponding Wald-based confidence intervals had good coverage. Finally, we discuss the possibilities for applying the standard errors in practical test use in education and psychology. The procedure is provided via the R function check.norms, which is available in the mokken package.

    This manual was prepared by and for the United Stated Advanced Battery Consortium (USABC) Electrochemical Energy Storage Team. It is based on the targets established for 12 Volt Start/Stop energy storage development and is similar (with some important changes) to an earlier manual for the former FreedomCAR program. The specific procedures were developed primarily to characterize the performance of energy storage devices relative to the USABC requirements. However, it is anticipated that these procedures will have some utility for characterizing 12 Volt Start/Stop hybrid energy storage device behavior in general.

    Dyslexia is the most commonly occurring learning disability in the United States, characterized by difficulties with word recognition, spelling, and decoding. A growing body of literature suggests that deficits in motor skill performance exist in the dyslexic population. This study compared the performance of children with and without dyslexia on different subtests of the Test of Gross Motor Development and Movement Assessment Battery for Children and assessed whether there were developmental changes in the scores of the dyslexic group. Participants included 26 dyslexic children (19 boys and 7 girls; 9.5 yr. old, SD = 1.7) and 23 age- and sex-matched typically developing (17 boys and 6 girls; 9.9 yr. old, SD = 1.3) children as a control group. Mann-Whitney U tests indicated that the dyslexic group performed significantly lower than the control group only on the Total Balance subtest of the Movement Assessment Battery for Children. Additionally, the young dyslexic group performed significantly better on the Total Balance subtest, compared to the older dyslexic group. These results suggest that cerebellar dysfunction may account for differences in performance.

    Several anatomo-clinical investigations have shown that familiar face recognition disorders not due to high level perceptual defects are often observed in patients with lesions of the right anterior temporal lobe (ATL). The meaning of these findings is, however, controversial, because some authors claim that these patients show pure instances of modality-specific 'associative prosopagnosia', whereas other authors maintain that in these patients voice recognition is also impaired and that these patients have a 'multimodal person recognition disorder'. To solve the problem of the nature of famous faces recognition disorders in patients affected by right ATL lesions, it is therefore very important to verify with formal tests if these patients are or are not able to recognize others by voice, but a direct comparison between the two modalities is hindered by the fact that voice recognition is more difficult than face recognition. To circumvent this difficulty, we constructed a test battery in which subjects were requested to recognize the same persons (well-known at the national level) through their faces and voices, evaluating familiarity and identification processes. The present paper describes the 'Famous People Recognition Battery' and reports the normative data necessary to clarify the nature of person recognition disorders observed in patients affected by right ATL lesions.

    Skin sensitivity to sensory stimuli varies among different body areas. A standardized clinical quantitative sensory testing (QST) battery, established for the diagnosis of neuropathic pain, was used to assess whether the magnitude of differences between test sites reaches clinical significance. Ten different sensory QST measures derived from thermal and mechanical stimuli were obtained from 21 healthy volunteers (10 men) and used to create somatosensory profiles bilateral from the dorsum of the hands (the standard area for the assessment of normative values for the upper extremities as proposed by the German Research Network on Neuropathic Pain) and bilateral at volar forearms as a neighboring nonstandard area. The parameters obtained were statistically compared between test sites. Three of the 10 QST parameters differed significantly with respect to the "body area," that is, warmth detection, thermal sensory limen, and mechanical pain thresholds. After z-transformation and interpretation according to the QST battery's standard instructions, 22 abnormal values were obtained at the hand. Applying the same procedure to parameters assessed at the nonstandard site forearm, that is, z-transforming them to the reference values for the hand, 24 measurements values emerged as abnormal, which was not significantly different compared with the hand (P=0.4185). Sensory differences between neighboring body areas are statistically significant, reproducing prior knowledge. This has to be considered in scientific assessments where a small variation of the tested body areas may not be an option. However, the magnitude of these differences was below the difference in sensory parameters that is judged as abnormal, indicating a robustness of the QST instrument against protocol deviations with respect to the test area when using the method of comparison with a 95 % confidence interval of a reference dataset.

    Clinical test batteries for evaluation of knee function after injury to the Anterior Cruciate Ligament (ACL) should be valid and feasible, while reliably capturing the outcome of rehabilitation. There is currently a lack of consensus as to which of the many available assessment tools for knee function that should be included. The present aim was to use a statistical approach to investigate the contribution of frequently used tests to avoid redundancy, and filter them down to a proposed comprehensive and yet feasible test battery for long-term evaluation after ACL injury. In total 48 outcome variables related to knee function, all potentially relevant for a long-term follow-up, were included from a cross-sectional study where 70 ACL-injured (17-28 years post injury) individuals were compared to 33 controls. Cluster analysis and logistic regression were used to group variables and identify an optimal test battery, from which a summarized estimator of knee function representing various functional aspects was derived. As expected, several variables were strongly correlated, and the variables also fell into logical clusters with higher within-correlation (max ρ = 0.61) than between clusters (max ρ = 0.19). An extracted test battery with just four variables assessing one-leg balance, isokinetic knee extension strength and hop performance (one-leg hop, side hop) were mathematically combined to an estimator of knee function, which acceptably classified ACL-injured individuals and controls. This estimator, derived from objective measures, correlated significantly with self-reported function, e.g. Lysholm score (ρ = 0.66; p<0.001). The proposed test battery, based on a solid statistical approach, includes assessments which are all clinically feasible, while also covering complementary aspects of knee function. Similar test batteries could be determined for earlier phases of ACL rehabilitation or to enable longitudinal monitoring. Such developments, established on a well

    Full Text Available Energy Recovery Battery Testing Systems (ERBTS plays an important role in battery manufacture. The conventional ERBTS configuration contains a fundamental transformer, and a bidirectional Direct Current (DC–DC and Alternating Current (AC–DC converter. All ERBTS are connected in parallel, thus constituting a special and complicated AC micro-grid system. Aiming at addressing their low energy recovery efficiency, complex grid-connected control algorithm issues for islanded detection, and complicated power circuit topology issues, a hierarchical DC-link voltage hybrid AC–DC micro-grid that contains composite energy storing devices is proposed. Moreover, an energy management optimal scheme for the proposed scheme is put forward. The system configuration of the proposed scheme is described in detail. Compared to the conventional scheme, the proposed scheme has the merits of simplified power circuit topology, no need for phase synchronous control, and much higher energy recovery efficiency and reliability. The validity and effectiveness of the proposed technique is verified through numerous experimental results.

    2016-01-01

    Full Text Available Electric vehicle (EV manufacturers are employing cylindrical format cells in the construction of the vehicles’ battery systems. There is evidence to suggest that both the academic and industrial communities have evaluated cell degradation due to vibration and other forms of mechanical loading. The primary motivation is often the need to satisfy the minimum requirements for safety certification. However, there is limited research that quantifies the durability of the battery and in particular, how the cells will be affected by vibration that is representative of a typical automotive service life (e.g., 100,000 miles. This paper presents a study to determine the durability of commercially available 18,650 cells and quantifies both the electrical and mechanical vibration-induced degradation through measuring changes in cell capacity, impedance and natural frequency. The impact of the cell state of charge (SOC and in-pack orientation is also evaluated. Experimental results are presented which clearly show that the performance of 18,650 cells can be affected by vibration profiles which are representative of a typical vehicle life. Consequently, it is recommended that EV manufacturers undertake vibration testing, as part of their technology selection and development activities to enhance the quality of EVs and to minimize the risk of in-service warranty claims.

    The increasing number of patients with chronic pain in Japan has become a major issue in terms of the patient's quality of life, medical costs, and related social problems. Pain is a multi-dimensional experience with physiological, affective, cognitive, behavioral and social components, and recommended to be managed via a combination of bio-psycho-social aspects. However, a biomedical approach is still the dominant method of pain treatment in Japan. The current study aimed to evaluate comprehensive psychological functions and processes in Japanese chronic pain patients. The Rorschach Comprehensive System was administered to 49 in-patients with non-malignant chronic pain. Major variables and frequencies from the test were then compared to normative data from non-patient Japanese adults by way of the t-test and chi-square test. Patients exhibited high levels of emotional distress with a sense of helplessness with regard to situational stress, confusion, and ambivalent feelings. These emotions were managed by the patients in an inappropriate manner. Cognitive functions resulted in moderate dysfunction in all stages. Information processing tended to focus upon minute features in an inflexible manner. Mediational dysfunction was likely to occur with unstable affective conditions. Ideation was marked by pessimistic and less effective thinking. Since patients exhibited negative self-perception, their interpersonal relationship skills tended to be ineffective. Originally, our patients displayed average psychological resources for control, stress tolerance, and social skills for interpersonal relationships. However, patient coping styles were either situation- or emotion-dependent, and patients were more likely to exhibit emotional instability influenced by external stimuli, resulting in increased vulnerability to pain. Data gathered from the Rorschach test suggested psychological approaches to support chronic pain patients that are likely to be highly beneficial, and we

    To examine the internal consistency, test-retest reliability, and responsiveness of the Movement Assessment Battery for Children-Second Edition (MABC-2) Test for children with developmental coordination disorder (DCD). One hundred and forty-four Taiwanese children with DCD aged 6 to 12 years (87 males, 57 females) were tested on three separate occasions: two baseline measurements with a 20-day interval before the intervention, and a follow-up measurement after 6 months of rehabilitation. The therapists rated the performance of children in school-related physical tasks at baseline and after intervention. Internal consistency for the MABC-2 Test was α = 0.90. Test-retest reliability for the total score was excellent, with an intraclass correlation coefficient of 0.97. A small to medium magnitude of treatment effect was captured by the MABC-2 Test. The minimal detectable change (MDC) was 0.28 points whereas the minimal important difference (MID) values were from 2.36 to 2.50. All subscales except balance showed acceptable validity in differentiating groups of children whose physical performance had improved or remained stable. The MABC-2 Test is a reliable and valid measure to assess motor competence in children with DCD. The MID and MDC scores provide the reference point for clinical decision-making in managing the individual child. © The Authors. Developmental Medicine & Child Neurology © 2012 Mac Keith Press.

  5. Content Validity Index and Intra- and Inter-Rater Reliability of a New Muscle Strength/Endurance Test Battery for Swedish Soldiers.

    Helena Larsson

    Full Text Available The objective of this study was to examine the content validity of commonly used muscle performance tests in military personnel and to investigate the reliability of a proposed test battery. For the content validity investigation, thirty selected tests were those described in the literature and/or commonly used in the Nordic and North Atlantic Treaty Organization (NATO countries. Nine selected experts rated, on a four-point Likert scale, the relevance of these tests in relation to five different work tasks: lifting, carrying equipment on the body or in the hands, climbing, and digging. Thereafter, a content validity index (CVI was calculated for each work task. The result showed excellent CVI (≥0.78 for sixteen tests, which comprised of one or more of the military work tasks. Three of the tests; the functional lower-limb loading test (the Ranger test, dead-lift with kettlebells, and back extension, showed excellent content validity for four of the work tasks. For the development of a new muscle strength/endurance test battery, these three tests were further supplemented with two other tests, namely, the chins and side-bridge test. The inter-rater reliability was high (intraclass correlation coefficient, ICC2,1 0.99 for all five tests. The intra-rater reliability was good to high (ICC3,1 0.82-0.96 with an acceptable standard error of mean (SEM, except for the side-bridge test (SEM%>15. Thus, the final suggested test battery for a valid and reliable evaluation of soldiers' muscle performance comprised the following four tests; the Ranger test, dead-lift with kettlebells, chins, and back extension test. The criterion-related validity of the test battery should be further evaluated for soldiers exposed to varying physical workload.

    Proponents of the surface stimulation treatment of idiopathic scoliosis have reported approximately 75-85% success rates in arresting progressive curvatures. Although encouraging, these results do not appear to be better than those of the more traditional brace programs. Now recognizing electrical stimulation as a viable alternative to bracing, supporters have advocated the psychologic and physical freedom with electrical stimulation as a major advantage over brace treatment. However, to date, there have been no objective psychologic studies to substantiate these claims. This prospective study was devised to detect any significant differences between a group of patients treated in a TLSO or Milwaukee brace and a group of patients treated with lateral electrical surface stimulation (LESS) (ScoliTron). The study consisted of 40 female private patients with idiopathic scoliosis treated for a minimum of 3 months. Each patient was given a set of seven standardized psychologic tests and an observer rating by the treating physician or physical therapist working with the patient. Results of the Psychological Epidemiology Research Interview (PERI) revealed that the LESS group had significantly higher self esteem than the brace group. The brace patients demonstrated a much greater perception of directed hostility than the LESS group. The coping response inventory showed the brace group to manifest a more primitive coping mechanism than the LESS group. The brace group attempted to avoid problems associated with their disease, rather than cope with them as the LESS group was better able to do. The brace group focused more on their emotions than the realistic problems of their disease.(ABSTRACT TRUNCATED AT 250 WORDS)

    Valid and reliable measures of children's physical fitness are necessary for investigating the relationship between children's physical fitness and children's health. Objective The objective of this study was to estimate the feasibility, internal consistency, convergent construct validity, and test-retest reliability of a new, functional, and easily administered test battery for measuring children's physical fitness. The study was a cross-sectional descriptive survey applying physical fitness tests across age groups 5 to 12 years. Each of the 9 items in the test battery consists of a compound motor activity that recruits various combinations of endurance, strength (force-generating capacity), agility, balance, and motor coordination: standing broad jump, jumping a distance of 7 m on 2 feet, jumping a distance of 7 m on one foot, throwing a tennis ball with one hand, pushing a medicine ball with 2 hands, climbing wall bars, performing a 10 × 5 m shuttle run, running 20 m as fast as possible, and performing a reduced Cooper test (6 minutes). The test battery was administered to 195 children (aged 5-12 years) from 4 schools and kindergartens in Norway. Overall, the children in each age group were able to perform all of the test items, indicating the suitability of the test battery for children as young as 5 years of age. With increasing age, total scores improved linearly, indicating the adequate sensitivity of the test battery for the age range examined in this study. Furthermore, even with the modest sample size used in this study, total scores were normally distributed, thereby fulfilling the necessary assumptions of most statistical procedures. For investigating the reliability of the test battery, 24 children (mean age=8.6 years) in one class were retested 1 week later. Test-retest correlations were high, with intraclass correlation coefficients for individual test items and total score ranging from .54 to .92. Limitations The survey was limited to samples of 5

    Full Text Available Background The paper presents the authors’ own research, which points to the possibility of applying the Rorschach test in the clinical diagnosis of personality disorders. Participants and procedure The clinical research was conducted in the years 2010-2013 in the Neurosis Treatment Center and in the Mental Health Outpatient Clinic. The study population comprised individuals with a medical diagnosis of neurotic personality organization as well as patients with more severely disorganized personality structure. The research participants had never undergone psychological evaluation for personality disorders (for instance, they had never taken the Rorschach test, and therefore it seemed rather difficult to verify the accuracy of the medical diagnoses which they had received, concerning the level of personality destabilization. Eighty Polish individuals participated in the research. The study population comprised 38 males (47.50% and 42 females (52.50%. The mean age of women was 30.40 (SD = 7.67. The men’s mean age was 35.10 (SD = 8.73. The examined females were somewhat younger than the male subjects. Methods: Rorschach test, clinical interview. Results The statistical procedures applied in the present study allowed us to conduct empirical examination of the indicators of the investigated variables constituting the major psychological criteria for describing psychological functioning of personality, and thus to identify the main characteristics of neurotic as well as borderline level of personality organization. Analysis of the data obtained as a result of this research allowed us to distinguish two significantly different clusters in the group of 80 examined individuals. Conclusions The results of the present investigation indicate that despite the fact that the examined individuals displayed symptoms of different medical diagnoses (F40 and F60, the subjects comprising cluster 1 exhibited a higher level of personality structure compared with

  10. A critical discussion of null hypothesis significance testing and statistical power analysis within psychological research

    2007-01-01

    The uses of null hypothesis significance testing (NHST) and statistical power analysis within psychological research are critically discussed. The article looks at the problems of relying solely on NHST when dealing with small and large sample sizes. The use of power-analysis in estimating...... the potential error introduced by small and large samples is advocated. Power analysis is not recommended as a replacement to NHST but as an additional source of information about the phenomena under investigation. Moreover, the importance of conceptual analysis in relation to statistical analysis of hypothesis...

    Full Text Available Various factors in South African workplaces, ranging from unemployment and equity considerations to rapid occupational change driven by technological inputs, have placed greater emphasis on effective selection and development of human resources. This leads to greater demands on psychological assessment in the organizational setting with respect to ensuring responsible, ethical and equitable assessment. The study aims to investigate the extent and purposes of psychological test usage, the influence of the changing world of work on assessment, equity and cross-cultural applicability of tests and competence of test users in South Africa. The results are based on twenty two structured individual interviews, which were conducted with purposively sampled stakeholders from various economic sectors. Opsomming Verskeie faktore in Suid-Afrikaanse werkomgewing, wat wissel van werkloosheid en billikheidsoorwegings tot by vinnig veranderende beroepsomstandighede as gevolg van tegnologiese ontwikkeling, plaas toenemende druk op die doeltreffende keuring en ontwikkeling van menslike hulpbronne. Dit lei tot toenemende eise wat in die organisasie konteks aan sielkundige meting gestel word om verantwoordelike, etiese en billike assessering te verseker. Hierdie studie was daarop gerig om die doel met en omvang van die gebruik van sielkundige toetse, die invloed van die veranderende wêreld van werk op die assessering, billike en kruiskulturele toepaslikheid van toetse, asook die bevoegdheid van toetsgebruikers in Suid-Afrika te ondersoek. Die resultate is gebaseer op ’n doelgerigte steekproef van twee-en-twintig gestruktureerde onderhoude wat met belanghebbers uit verskillende ekonomiese sektore, gevoer is.

  12. A core in vitro genotoxicity battery comprising the Ames test plus the in vitro micronucleus test is sufficient to detect rodent carcinogens and in vivo genotoxins.

    In vitro genotoxicity testing needs to include tests in both bacterial and mammalian cells, and be able to detect gene mutations, chromosomal damage and aneuploidy. This may be achieved by a combination of the Ames test (detects gene mutations) and the in vitro micronucleus test (MNvit), since the latter detects both chromosomal aberrations and aneuploidy. In this paper we therefore present an analysis of an existing database of rodent carcinogens and a new database of in vivo genotoxins in terms of the in vitro genotoxicity tests needed to detect their in vivo activity. Published in vitro data from at least one test system (most were from the Ames test) were available for 557 carcinogens and 405 in vivo genotoxins. Because there are fewer publications on the MNvit than for other mammalian cell tests, and because the concordance between the MNvit and the in vitro chromosomal aberration (CAvit) test is so high for clastogenic activity, positive results in the CAvit test were taken as indicative of a positive result in the MNvit where there were no, or only inadequate data for the latter. Also, because Hprt and Tk loci both detect gene-mutation activity, a positive Hprt test was taken as indicative of a mouse-lymphoma Tk assay (MLA)-positive, where there were no data for the latter. Almost all of the 962 rodent carcinogens and in vivo genotoxins were detected by an in vitro battery comprising Ames+MNvit. An additional 11 carcinogens and six in vivo genotoxins would apparently be detected by the MLA, but many of these had not been tested in the MNvit or CAvit tests. Only four chemicals emerge as potentially being more readily detected in MLA than in Ames+MNvit--benzyl acetate, toluene, morphine and thiabendazole--and none of these are convincing cases to argue for the inclusion of the MLA in addition to Ames+MNvit. Thus, there is no convincing evidence that any genotoxic rodent carcinogens or in vivo genotoxins would remain undetected in an in vitro test battery

    This project, the research and development of a phosphoric acid fuel cell/battery power source integrated into test-bed buses, began as a multi-phase U.S. Department of Energy (DOE) project in 1989. Phase I had a goal of developing two competing half-scale (25 kW) brassboard phosphoric acid fuel cell systems. An air-cooled and a liquid-cooled fuel cell system were developed and tested to verify the concept of using a fuel cell and a battery in a hybrid configuration wherein the fuel cell supplies the average power required for operating the vehicle and a battery supplies the `surge` or excess power required for acceleration and hill-climbing. Work done in Phase I determined that the liquid-cooled system offered higher efficiency.

    Humans have the abilities to perceive, produce, and synchronize with a musical beat, yet there are widespread individual differences. To investigate these abilities and to determine if a dissociation between beat perception and production exists, we developed the Harvard Beat Assessment Test (H-BAT), a new battery that assesses beat perception and production abilities. H-BAT consists of four subtests: (1) music tapping test (MTT), (2) beat saliency test (BST), (3) beat interval test (BIT), and (4) beat finding and interval test (BFIT). MTT measures the degree of tapping synchronization with the beat of music, whereas BST, BIT, and BFIT measure perception and production thresholds via psychophysical adaptive stair-case methods. We administered the H-BAT on thirty individuals and investigated the performance distribution across these individuals in each subtest. There was a wide distribution in individual abilities to tap in synchrony with the beat of music during the MTT. The degree of synchronization consistency was negatively correlated with thresholds in the BST, BIT, and BFIT: a lower degree of synchronization was associated with higher perception and production thresholds. H-BAT can be a useful tool in determining an individual's ability to perceive and produce a beat within a single session.

    There are many ways to assess face perception skills. In this study, we describe a novel task battery FEAST (Facial Expressive Action Stimulus Test) developed to test recognition of identity and expressions of human faces as well as stimulus control categories. The FEAST consists of a neutral and emotional face memory task, a face and shoe identity matching task, a face and house part-to-whole matching task, and a human and animal facial expression matching task. The identity and part-to-whole matching tasks contain both upright and inverted conditions. The results provide reference data of a healthy sample of controls in two age groups for future users of the FEAST.

  19. Is sadness blue? The problem of using figurative language for emotions on psychological tests.

    Science.gov (United States)

    Barchard, Kimberly A; Grob, Kelly E; Roe, Matthew J

    2017-04-01

    Psychological tests sometimes include figurative language like I feel blue. However, figurative language may not mean the same thing cross-culturally. Previous research found cross-cultural evidence for 14 conceptual metaphors and metonymies for emotions (e.g., sadness is blue). Our two studies asked participants (total n = 795) in the USA and India whether happiness, sadness, anger, and fear are associated with certain descriptors (blue, down, bright, etc.). Most participants in both countries endorsed ten of the 14 hypothesized associations; however, the percentage of participants endorsing an association was often far from 100 %. For example, in the USA, only 71.7 % associated hot with anger and only 65.9 % associated blue with sadness. Moreover, descriptors were often associated with more than one emotion. Furthermore, only two associations (happiness is up and bright) were endorsed by more than 90 % of participants in both countries and had descriptors that were not associated with additional emotions. We conclude that figurative language is often ambiguous and should be used with caution on psychological tests unless there is evidence the language is understood cross-culturally. Advice to this effect is currently lacking from psychometrics textbooks and should be added.

    Looi, Valerie; Winter, Philip; Anderson, Ilona; Sucher, Catherine

    2011-08-01

    The purpose of this study was to develop a music quality rating test battery (MQRTB) and pilot test it by comparing appraisal ratings from cochlear implant (CI) recipients using the fine-structure processing (FSP) and high-definition continuous interleaved sampling (HDCIS) speech processing strategies. The development of the MQRTB involved three stages: (1) Selection of test items for the MQRTB; (2) Verification of its length and complexity with normally-hearing individuals; and (3) Pilot testing with CI recipients. Part 1 involved 65 adult listeners, Part 2 involved 10 normally-hearing adults, and Part 3 involved five adult MED-EL CI recipients. The MQRTB consisted of ten songs, with ratings made on scales assessing pleasantness, naturalness, richness, fullness, sharpness, and roughness. Results of the pilot study, which compared FSP and HDCIS for music, indicated that acclimatization to a strategy had a significant effect on ratings (p < 0.05). When acclimatized to FSP, the group rated FSP as closer to 'exactly as I want it to sound' than HDCIS (p < 0.05), and that HDCIS sounded significantly sharper and rougher than FSP. However when acclimatized to HDCIS, there were no significant differences between ratings. There was no effect of song familiarity or genre on ratings. Overall the results suggest that the use of FSP as the default strategy for MED-EL recipients would have a positive effect on music appreciation, and that the MQRTB is an effective tool for assessing music sound quality.

    The aim of this study was to test the reliability and validity of the Psychological Conditions Scale (PCS), a measure of drivers of engagement in hospital-based nurses. Research suggests drivers of engagement are positive links to patient, employee, and hospital outcomes. Although this scale has been used in other occupations, it has not been tested in nursing. A cross-sectional, methodological study using a convenience sample of 200 nurses in a large Magnet® hospital in New Jersey. Cronbach's α's ranged from .64 to .95. Principal components exploratory factor analysis with oblique rotation revealed that 13 items loaded unambiguously in 3 domains and explained 76% of the variance. Mean PCS scores ranged from 3.62 to 4.68 on a 5-point Likert scale. The scale is an adequate measure of drivers of engagement in hospital-based nurses. Leadership efforts to promote the facilitators of engagement are recommended.

  5. The Psychological Challenges of Replacing Conventional Karyotyping with Genomic SNP Array Analysis in Prenatal Testing

    Directory of Open Access Journals (Sweden)

    2014-07-01

    Full Text Available Pregnant couples tend to prefer a maximum of information about the health of their fetus. Therefore, we implemented whole genome microarray instead of conventional karyotyping (CK for all indications for prenatal diagnosis (PND. The array detects more clinically relevant anomalies, including early onset disorders, not related to the indication and more genetic anomalies of yet unquantifiable risk, so-called susceptibility loci (SL for mainly neurodevelopmental disorders. This manuscript highlights the psychological challenges in prenatal genetic counselling when using the array and provides counselling suggestions. First, we suggest that pre-test decision counselling should emphasize deliberation about what pregnant couples wish to learn about the future health of their fetus more than information about possible outcomes. Second, pregnant couples need support in dealing with SL. Therefore, in order to consider the SL in a proportionate perspective, the presence of phenotypes associated with SL in the family, the incidence of a particular SL in control populations and in postnatally ascertained patients needs highlighting during post-test genetic counselling. Finally, the decision that couples need to make about the course of their pregnancy is more complicated when the expected phenotype is variable and not quantifiable. Therefore, during post-test psychological counseling, couples should concretize the options of continuing and ending their pregnancy; all underlying feelings and thoughts should be made explicit, as well as the couple’s resources, in order to attain adequate decision-making. As such, pre- and post-test counselling aids pregnant couples in handling the uncertainties that may accompany offering a broader scope of genetic PND using the array.

    Full Text Available HIV-associated neurocognitive disorders (HAND remain prevalent despite improved antiretroviral treatment (ART, and it is essential to have a sensitive and specific HAND screening tool.Participants were 200 HIV-infected US military beneficiaries, managed early in the course of HIV infection, had few comorbidities, and had open access to ART. Participants completed a comprehensive, seven-domain (16-test, neuropsychological battery (∼120 min; neurocognitive impairment (NCI was determined using a standardized score derived from demographically adjusted T-scores (global deficit score ≥0.5. Restricting the estimated administration time of the screening battery to < = 20 minutes, we examined the sensitivity and specificity of detecting NCI for all possible combinations of 2-, 3-, and 4- tests from the comprehensive battery.Participants were relatively healthy (median CD4 count: 546 cells/mm(3 with 64% receiving ART. Prevalence of NCI was low (19%. The best 2-test screener included the Stroop Color Test and the Hopkins Verbal Learning Test-Revised (11 min; sensitivity = 73%; specificity = 83%; the best 3-test screener included the above measures plus the Paced Auditory Serial Addition Test (PASAT; 16 min; sensitivity = 86%; specificity = 75%. The addition of Action Fluency to the above three tests improved specificity (18 min; sensitivity = 86%; specificity = 87%.Combinations of widely accepted neuropsychological tests with brief implementation time demonstrated good sensitivity and specificity compared to a time intensive neuropsychological test battery. Tests of verbal learning, attention/working memory, and processing speed are particularly useful in detecting NCI. Utilizing validated, easy to administer, traditional neuropsychological tests with established normative data may represent an excellent approach to screening for NCI in HIV.

    2013-01-01

    The author of this study proposed and examined a theoretical model in which meaningful activity fulfills basic psychological needs and contributes to meaning in life. Hypotheses derived from the Meaningful Activity and Life Meaning model and tested within this study included: (1) meaningful activity will be associated with meaning in life, (2) meaningful activity will be associated with basic psychological needs, and (3) basic psychological needs will partially mediate the relationship between meaningful activity and meaning in life. Structural equation modeling with latent variables was used to test the study hypotheses. A total of 591 undergraduate and graduate students completed the Engagement in Meaningful Activities Survey, the Basic Psychological Needs Scales (i.e., autonomy, competence, and relatedness), and the Presence subscale of the Meaning in Life Questionnaire. Results from the study were in full support of each hypothesis and indicate the important role meaningful activity may serve in fostering meaning in life. Copyright 2013, SLACK Incorporated.

    Little is known about risk factors for suicide ideation and attempts among domestic violence offenders. Guided by the interpersonal-psychological theory of suicide, this cross-sectional study examined risk factors for suicide ideation and attempts among 312 men and 84 women arrested for domestic violence and mandated to attend batterer intervention programs. Men reported greater capability for suicide, but no gender differences were found in perceived burdensomeness and thwarted belongingness. After controlling for correlates of suicide ideation, perceived burdensomeness-but not thwarted belongingness or its interaction with perceived burdensomeness-associated with suicide ideation. Suicide attempters exhibited greater perceived burdensomeness, drug use and problems, borderline personality disorder symptoms, depressive symptoms, and suicide ideation, but not capability for suicide, than nonattempters. Gender did not moderate the associations of the IPTS constructs with suicide ideation and attempts. These findings parallel tests of the interpersonal-psychological theory in other samples. Additional work is needed to identify factors that distinguish risk for suicide ideation from risk for suicide attempts among domestic violence offenders. Copyright © 2017 Elsevier Ireland Ltd.

    José Gregorio Ortiz-Rodríguez

    2013-06-01

    Full Text Available The competencies assessment tests “Saber 11” made by the ICFES are considered a benchmark for entry to higher education, since it is assumed that these predict academic performance. From the theoretical framework of evaluation and measurement and the Competencies Theory, which state an objective assessment of psychological attributes and the relationship between the data and the competence itself, a descriptive correlational study was made. Through this study, it was intended to establish the relationship between the ICFES Exam scores and the grades achieved in disciplinary subjects in the first semester of the psychology program at the Corporación Universitaria Minuto de Dios in Bogota, Colombia. It was found a positive relationship between the overall scores in the ICFES exam and academic performance in disciplinary subjects of the program. Moreover, specific relationships between the scores in the areas of language, mathematics and social sciences, and disciplinary subjects were found. For this reason, it is concluded that performance in these areas is a predictor of performance in disciplinary subjects.

    2015-04-01

    This study aimed to investigate the influence of professional nursing practice environment and psychological empowerment on nurses' work engagement. Previous researchers have acknowledged the positive influence that nurse work environment and psychological empowerment have on engagement. However, less is known about the mechanisms that explain the links between them. A predictive, non-experimental design was used to test the model in a random sample of 300 clinical nurses from two tertiary first class hospitals of Tianjin, China. The Utrecht Work Engagement Scale, the Practice Environment Scale of the Nursing Work Index and the Psychological Empowerment Scale were used to measure the study variables. Structural equation modelling revealed a good fit of the model to the data based on various fit indices (P = 0.371, χ(2) /df = 1.056, goodness of fit index = 0.967), which indicated that both professional practice environment and psychological empowerment could positively influence work engagement directly, and professional practice environment could also indirectly influence work engagement through the mediation of psychological empowerment. The study hypotheses were supported. Psychological empowerment was found to mediate the relationship between practice environments and work engagement. Administrators should provide a professional nursing practice environment and empower nurses psychologically to increase nurse engagement. © 2013 John Wiley & Sons Ltd.

    Full Text Available In this paper, aiming at the energy loss and harmonic problems in the conventional power accumulator battery pack testing system (PABPTS, an improved multi-functional energy recovery PABPTS (ERPABPTS for electric vehicles (EVs was proposed. The improved system has the functions of harmonic detection, suppression, reactive compensation and energy recovery. The ERPABPTS, which contains a bi-directional buck-boost direct current (DC-DC converter and a bi-directional alternating current (AC-DC converter with an inductor-capacitor-inductor (LCL type filter interfacing to the AC-grid, is proposed. System configuration and operation principle of the combined system are discussed first, then, the reactive compensation and harmonic suppression controller under balanced grid-voltage condition are presented. Design of a fourth order band-pass Butterworth filter for current harmonic detection is put forward, and the reactive compensator design procedure considering the non-linear load is also illustrated. The proposed scheme is implemented in a 175-kW prototype in the laboratory. Simulation and experimental results show that the combined configuration can effectively realize energy recovery for high accuracy current test requirement, meanwhile, can effectively achieve reactive compensation and current harmonic suppression.

    Anxiety and depression are common after heart transplantation. This study aimed to pilot test the feasibility of a clinical model of psychological care for heart transplant recipients. The model of care involved nurse-led screening for anxiety and depression followed by referral for a course of telephone-delivered cognitive behaviour therapy as well as co-ordination of communication with on-going specialist and primary care services. A pilot randomised controlled trial was conducted. Heart transplant recipients who self-reported at least mild anxiety or depressive symptoms were randomised (defined as a score higher than 5 on the Patient Health Questionnaire-9 or the Generalized Anxiety Disorder-7 [GAD-7], or a score higher than 20 on the Kessler Psychological Distress Scale [K10]). The primary outcome was assessment of feasibility of conducting a larger trial, which included identification of recruitment and attrition rates as well as the acceptability of the intervention. Follow-up was conducted at 9 weeks and 6 months. One hundred twenty-two of the 126 (97 %) heart transplant recipients assessed on their attendance at the outpatient clinic met the study eligibility criteria. Of these patients, 88 (72 %) agreed to participate. A moderate proportion of participants (n = 20; 23 %) reported at least mild symptoms of anxiety or depression. Five participants were excluded because they were currently receiving psychological counselling, two withdrew before randomisation and the remaining 13 were randomised (seven to intervention and six to usual care). The majority of the randomised participants were male (n = 9; 69 %) and aged over 60 (range 35-73). Median length of time post-transplant was 9.5 years (ranging from 1 to 19 years). On enrolment, 3 randomised participants were taking anti-depressants. One intervention group participant withdrew and a further 3 (50 %) declined the telephone-delivered CBT sessions; all because of restrictions associated

    This study examines ethnic differences in the prevalence of bullying victimization by peers as well as the associations between bullying victimization and psychological distress with relevant ecological factors including parental supervision, school support, and community safety. The study utilized the 2011-2012 California Health Interview Survey (CHIS) Adolescents Data, which was collected in the United States using a multi-stage stratified sampling design with a Random Digit-Dial method. The final study sample contained a total of 2367 adolescents, comprised of 48.7% Whites, followed by 35.8% Latinos, 11.1% Asians, and 4.4% African Americans. About 49.3% were males with an overall mean age of 14.6 (sd = 1.7). Results showed that there were significant differences in rates of bullying victimization among the four surveyed ethnic subgroups of adolescents. Black adolescents reported the highest and Asian adolescents the lowest level of victimization. The results of the SEM test using the calibration sample revealed an adequate fit to the data (CFI = 0.95, RMSEA = 0.04, Δχ 2 /Δdf = 2.99). Separate model tests with the four subgroups of adolescents revealed good fits with the subsample data with the exception of the subsample of African Americans. Additionally, results show that factors associated with psychological distress vary widely among the White, Latino and Asian subgroups.

    The land spreading of organic wastes in agriculture is a common practice in Europe, under the regulation of the Directive 86/278/EEC. One of the objectives of this Directive is to prevent harmful effects of organic wastes on soil, plants and animals. Despite this regulatory framework, there is still a lack of harmonized ecotoxicological test strategy to assess the environmental hazard of such wastes. The aim of this study was to provide a first step towards the a priori ecotoxicological assessment of organic wastes before their land use. For that purpose, nine different organic wastes were assessed using direct (i.e. terrestrial tests) and indirect (i.e. tests on water eluates) approaches, for a total of thirteen endpoints. Then, multivariate analyzes were used to discriminate the most relevant test strategy, among the application rates and bioassays used. From our results, a draft of test strategy was proposed, using terrestrial bioassays (i.e. earthworms and plants) and a concentration range between one and ten times the recommended application rates of organic wastes.

    One of the main goals for toxicologists working on the development of in vitro tests is to replace the animal-based eye irritation test. Inflammation is one of the mechanisms which have not been covered sufficiently by the existing in vitro ocular irritancy test systems. As there are major species differences between the human and rabbit eye inflammation mechanisms, the most relevant test system is the human eye itself. The current study focused on an evaluation of the practical availability of human corneal epithelial cells for routine eye irritancy testing. Human corneal epithelium cell cultures were used to assess the effects of lipopolysaccharide on IL-1 beta release. The findings indicated that cytokine release can be augmented by the presence of the complement system, which is normally found in tears. However, the corneal cells were found to be highly resistant to the complement system, which can be attributed to the very high expression of CD59, a powerful complement regulatory protein found in the corneal epithelium. It is estimated that discarded corneas from tissue banks could provide enough material for routine testing by this method.

    Although the executive function subtests of the Cambridge Neuropsychological Test Automated Battery (CANTAB) have been used to assess cognitive function in diverse psychiatric illnesses, few studies have verified the validity of this battery for Korean psychiatric patients. Therefore, this preliminary study evaluated the construct and concurrent validity of the executive function subtests of the CANTAB for Korean psychiatric patients by comparing it with subtests of the Computerized Neuropsychological Test (CNT). Three subtests of the CANTAB and three subtests of the CNT were administered to 36 patients diagnosed with either schizophrenia or bipolar disorder. Subtests of the CANTAB included the Intra/Extra-Dimensional Set Shift (IED), Stockings of Cambridge (SOC), and Spatial Working Memory (SWM). Differences between groups on each subtest as well as correlations between the subtests of the CANTAB and the CNT were assessed. The schizophrenia group performed significantly more poorly on the IED and the Wisconsin Card Sorting Test (WCST) compared with the bipolar disorder group. Additionally, correlation analyses revealed a significant correlation between the IED and the WCST; a positive correlation between the SOC and the Trail Making Test, Part B and the Stroop test; and a significant correlation between the SWM and the Stroop test. This study verified the construct and concurrent validity of the executive function subtests of the CANTAB for Korean psychiatric patients and suggests that the subtests of this battery would be useful and appropriate for assessing deficits in executive function in Korean clinical settings.

    Battery development and testing efforts at Phillips Laboratory fall into three main categories: nickel hydrogen, sodium sulfur, and solid state batteries. Nickel hydrogen work is broken down into a Low Earth Orbit (LEO) Life Test Program, a LEO Pulse Test Program, and a Hydrogen Embrittlement Investigation. Sodium sulfur work is broken down into a Geosynchronous Earth Orbit (GEO) Battery Flight Test and a Hot Launch Evaluation. Solid state polymer battery work consists of a GEO Battery Development Program, a Pulse Power Battery Small Business Innovation Research (SBIR), and an in-house evaluation of current generation laboratory cells. An overview of the program is presented.

    To study factors which influence the quality of life (QOL) in the elderly, we investigated the relationship between scores on the modified Philadelphia Geriatric Center (JPGC) Morale Scale and various other psychological tests in 51 elderly people residing in a long-term care facility. The JPGC Morale Scale score correlated with the scores for all sections of the Japanese version of the Cornell Medical Index (JCMI), but not with those for the Mini Mental State Examination, the Kohs block design test, the Bender Gestalt test and the activities of daily living (ADL). Both somatic and psychotic symptoms on the JCMI were correlated with the dementia behaviour disturbance scale score and walking ability according to the ADL. Subjects were further divided into four groups according to Fukamachi's neurotic discriminative diagram based on the JCMI. Scores for most sections of somatic and psychotic symptoms on the JCMI were elevated in proportion to the degree of neurotic tendencies in the elderly. These results indicate that the QOL of the elderly is influenced by subjective symptoms, but not by the degree of cognitive impairment or the ADL.

    2014-08-01

    In the real world, spoken communication occurs in complex environments that involve audiovisual speech cues, spatially separated sound sources, reverberant listening spaces, and other complicating factors that influence speech understanding. However, most clinical tools for assessing speech perception are based on simplified listening environments that do not reflect the complexities of real-world listening. In this study, speech materials from the QuickSIN speech-in-noise test by Killion, Niquette, Gudmundsen, Revit, and Banerjee [J. Acoust. Soc. Am. 116, 2395-2405 (2004)] were modified to simulate eight listening conditions spanning the range of auditory environments listeners encounter in everyday life. The standard QuickSIN test method was used to estimate 50% speech reception thresholds (SRT50) in each condition. A method of adjustment procedure was also used to obtain subjective estimates of the lowest signal-to-noise ratio (SNR) where the listeners were able to understand 100% of the speech (SRT100) and the highest SNR where they could detect the speech but could not understand any of the words (SRT0). The results show that the modified materials maintained most of the efficiency of the QuickSIN test procedure while capturing performance differences across listening conditions comparable to those reported in previous studies that have examined the effects of audiovisual cues, binaural cues, room reverberation, and time compression on the intelligibility of speech.

  11. Computerized adaptive testing of population psychological distress: simulation-based evaluation of GHQ-30.

    Goldberg's General Health Questionnaire (GHQ) items are frequently used to assess psychological distress but no study to date has investigated the GHQ-30's potential for adaptive administration. In computerized adaptive testing (CAT) items are matched optimally to the targeted distress level of respondents instead of relying on fixed-length versions of instruments. We therefore calibrate GHQ-30 items and report a simulation study exploring the potential of this instrument for adaptive administration in a longitudinal setting. GHQ-30 responses of 3445 participants with 2 completed assessments (baseline, 7-year follow-up) in the UK Health and Lifestyle Survey were calibrated using item response theory. Our simulation study evaluated the efficiency of CAT administration of the items, cross-sectionally and longitudinally, with different estimators, item selection methods, and measurement precision criteria. To yield accurate distress measurements (marginal reliability at least 0.90) nearly all GHQ-30 items need to be administered to most survey respondents in general population samples. When lower accuracy is permissible (marginal reliability of 0.80), adaptive administration saves approximately 2/3 of the items. For longitudinal applications, change scores based on the complete set of GHQ-30 items correlate highly with change scores from adaptive administrations. The rationale for CAT-GHQ-30 is only supported when the required marginal reliability is lower than 0.9, which is most likely to be the case in cross-sectional and longitudinal studies assessing mean changes in populations. Precise measurement of psychological distress at the individual level can be achieved, but requires the deployment of all 30 items.

    Pro-cognitive agents for chronic psychotic disorders (CPDs) might be detected via experimental medicine models, in which neural targets engaged by the drug predict sensitivity to the drug's pro-cognitive effects. This study aims to use an experimental medicine model to test the hypothesis that "target engagement" predicts pro-cognitive effects of the NMDA antagonist, memantine (MEM), in CPDs. MATRICS Consensus Cognitive Battery (MCCB) performance was assessed in CPD (n = 41) and healthy subjects (HS; n = 41) in a double-blind, randomized cross-over design of acute (single dose) MEM (placebo vs. 10 or 20 mg p.o.). Measures of prepulse inhibition (PPI) and mismatch negativity previously reported from this cohort substantiated target engagement. Biomarkers predicting MEM neurocognitive sensitivity were assessed. Testing confirmed MCCB deficits associated with CPD diagnosis, age, and anticholinergic exposure. MEM (20 mg p.o.) reduced MCCB performance in HS. To control for significant test order effects, an "order-corrected MEM effect" (OCME) was calculated. In CPD subjects, greater age, positive MEM effects on PPI, and SNP rs1337697 (within the ionotropic NMDA receptor gene, GRIN3A) predicted greater positive OCME with 20 mg MEM. An experimental medicine model to assess acute pro-cognitive drug effects in CPD subjects is feasible but not without challenges. A single MEM 20 mg dose had a negative impact on neurocognition among HS. In CPD patients, age, MEM effects on PPI, and rs1337697 predicted sensitivity to the neurocognitive effects of MEM. Any potential clinical utility of these predictive markers for pro-cognitive effects of MEM in subgroups of CPD patients cannot be inferred without a validating clinical trial.

    To fill an important gap in the psychometric assessment of children and adolescents with impaired vision, we designed a new battery of haptic tests, called Haptic-2D, for visually impaired and sighted individuals aged five to 18 years. Unlike existing batteries, ours uses only two-dimensional raised materials that participants explore using active touch. It is composed of 11 haptic tests, measuring scanning skills, tactile discrimination skills, spatial comprehension skills, short-term tactile memory, and comprehension of tactile pictures. We administered this battery to 138 participants, half of whom were sighted (n=69), and half visually impaired (blind, n=16; low vision, n=53). Results indicated a significant main effect of age on haptic scores, but no main effect of vision or Age × Vision interaction effect. Reliability of test items was satisfactory (Cronbach's alpha, α=0.51-0.84). Convergent validity was good, as shown by a significant correlation (age partialled out) between total haptic scores and scores on the B101 test (rp=0.51, n=47). Discriminant validity was also satisfactory, as attested by a lower but still significant partial correlation between total haptic scores and the raw score on the verbal WISC (rp=0.43, n=62). Finally, test-retest reliability was good (rs=0.93, n=12; interval of one to two months). This new psychometric tool should prove useful to practitioners working with young people with impaired vision. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Transgenic mouse models of Alzheimer's disease (AD) with abundant β-amyloid develop memory impairments. However, multiple nonmnemonic cognitive domains such as attention and executive control are also compromised early in AD individuals, but have not been routinely assessed in animal models. Here, we assessed the cognitive abilities of TgCRND8 mice-a widely used model of β-amyloid pathology-with a touch screen-based automated test battery. The test battery comprises highly translatable tests of multiple cognitive constructs impaired in human AD, such as memory, attention, and response control, as well as appropriate control tasks. We found that familial AD mutations affect not only memory, but also cause significant alterations of sustained attention and behavioral flexibility. Because changes in attention and response inhibition may affect performance on tests of other cognitive abilities including memory, our findings have important consequences for the assessment of disease mechanisms and therapeutics in animal models of AD. A more comprehensive phenotyping with specialized, multicomponent cognitive test batteries for mice might significantly advance translation from preclinical mouse studies to the clinic.

    The Bi-Digital O-Ring Test, originally developed by Dr. Omura, utilizes changes in the degree of strength of voluntary movements of muscles of the fingers under a definite muscle tonus, making Bi-Digital O-Rings, as an indicator of pathology in the body. Research in Sports Psychology can use the classical measurement methods and Bi-Digital O-Ring Test method comparatively and thus produce new findings regarding the reliability and certainty of the Bi-Digital O-Ring Test test. It seems probable that by using the non-invasive Bi-Digital O-Ring Test test, it is possible to measure enzymes, hormones and neuro-transmitters instantaneously and assess a sports person's actual psychological and physiological performance, and thereby help them reach their peak performance levels during both exercise and competitions.

  19. A novel automated behavioral test battery assessing cognitive rigidity in two genetic mouse models of autism.

    Full Text Available Repetitive behaviors are a key feature of many pervasive developmental disorders, such as autism. As a heterogeneous group of symptoms, repetitive behaviors are conceptualized into two main subgroups: sensory/motor (lower-order and cognitive rigidity (higher-order. Although lower-order repetitive behaviors are measured in mouse models in several paradigms, so far there have been no high-throughput tests directly measuring cognitive rigidity. We describe a novel approach for monitoring repetitive behaviors during reversal learning in mice in the automated IntelliCage system. During the reward-motivated place preference reversal learning, designed to assess cognitive abilities of mice, visits to the previously rewarded places were recorded to measure cognitive flexibility. Thereafter, emotional flexibility was assessed by measuring conditioned fear extinction. Additionally, to look for neuronal correlates of cognitive impairments, we measured CA3-CA1 hippocampal long term potentiation (LTP. To standardize the designed tests we used C57BL/6 and BALB/c mice, representing two genetic backgrounds, for induction of autism by prenatal exposure to the sodium valproate. We found impairments of place learning related to perseveration and no LTP impairments in C57BL/6 valproate-treated mice. In contrast, BALB/c valproate-treated mice displayed severe deficits of place learning not associated with perseverative behaviors and accompanied by hippocampal LTP impairments. Alterations of cognitive flexibility observed in C57BL/6 valproate-treated mice were related to neither restricted exploration pattern nor to emotional flexibility. Altogether, we showed that the designed tests of cognitive performance and perseverative behaviors are efficient and highly replicable. Moreover, the results suggest that genetic background is crucial for the behavioral effects of prenatal valproate treatment.

    This study aimed to determine the feasibility of an assessment of vision-related orientation and mobility (O&M) tasks in persons with severe vision loss. These tasks may be used for future low vision rehabilitation clinical assessments or as outcome measures in vision restoration trials. Forty legally blind persons (mean visual acuity logMAR 2.3, or hand movements) with advanced retinitis pigmentosa participated in the Orientation & Mobility-Very Low Vision (O&M-VLV) subtests from the Low Vision Assessment of Daily Activities (LoVADA) protocol. Four categories of tasks were evaluated: route travel in three indoor hospital environments, a room orientation task (the "cafe"), a visual exploration task (the "gallery"), and a modified version of the Timed Up and Go (TUG) test, which assesses re-orientation and route travel. Spatial cognition was assessed using the Stuart Tactile Maps test. Visual acuity and visual fields were measured. A generalized linear regression model showed that a number of measures in the O&M-VLV tasks were related to residual visual function. The percentage of preferred walking speed without an aid on three travel routes was associated with visual field (p orientation, which may be of benefit in vision restoration clinical trials.

    This replication study tested MacIntyre's Social Psychological Model of Strategy Use. Participants were 137 first-year college students (100 men and 37 women), all in their late teens or early 20s, learning English as a foreign language in a university in Taiwan. McIntyre specified three conditions for use of language-learning strategies in his model: awareness of the strategy, having a reason to use it, and not having a reason not to use it. Stepwise multiple regression analyses of data measured by Oxford's 50-item Strategy Inventory for Language Learning partially support this model because only Knowledge about the Strategy (representing the first condition) and Difficulty about Using It (representing the third condition) made significant independent contributions to the prediction of use of most of the 50 strategies. Close examination of the results poses questions about MacIntyre and Noels' thesis, as implied in their revised model, that reason to use the strategy and reason not to use the strategy are independent. The present replication suggests a need for further revision of the model. Use of methods more advanced than the multiple regression is recommended to test and refine the model.

    This study evaluated the synergy hypothesis of the Interpersonal-Psychological Theory of Suicide (IPTS), which argues thwarted belongingness and perceived burdensomeness are positively interactive in their association with suicide ideation, in a group of juvenile offenders. It also examined whether this prediction is differentially applicable across race/ethnicity or offense type. Participants included 590 adjudicated and confined male juveniles. Regression was used to test the association between suicide ideation and thwarted belongingness, perceived burdensomeness, and their interaction term. Subsequent analyses included tests of group interactions related to race/ethnicity and offense type. No interaction between thwarted belongingness and perceived burdensomeness was observed, despite adequate power. No significant group interactions were observed for race/ethnicity or offense type. However, results did show significant linear relationships between thwarted belongingness, perceived burdensomeness, and ideation, highlighting their potential utility as intervention targets in this at-risk population. Thus, although the current results are the first to show the basic IPTS risk factors generalize across race/ethnicity and offense type, they also failed to support that those factors were interactive, a primary IPTS claim. The absence of an interaction between thwarted belongingness and perceived burdensomeness suggests their role in suicide ideation for juvenile offenders may be more parsimonious than the IPTS proposes. © 2017 The American Association of Suicidology.

    Spatial neglect is most frequently observed after right-hemispheric stroke and is characterized by a failure to report, to respond, or to orient to stimuli presented to the contralesional side. Although many neglect patients show difficulties in accomplishing activities of daily living (ADL), to date the clinical assessment of neglect is based upon neuropsychological paper-and-pencil tests. Thus, essential information about the patient's functional status may be missed out. Accordingly, we aimed at developing a new neglect test battery that incorporates standardized ADL. Six conventional paper-and-pencil neglect tests and eight standardized ADL with newly developed neglect-specific scoring criteria and cut-off scores were administered to 68 right-hemispheric stroke patients. According to the neuropsychological tests 22 patients showed symptoms suggesting neglect, whereas 17 patients showed symptoms suggesting neglect according to the newly developed neglect test based upon ADL. Neglect-specific impairments in the neuropsychological tests were significantly associated with those in the ADL-based tests, although dissociations were observed in seven patients. Neglect severity (as reflected in the percentage of positive subtests) was comparable for both test batteries and both test instruments showed high interrater reliability. Voxel-based lesion-symptom mapping revealed that the severity of neglect according to the neuropsychological and ADL-based tests was significantly associated with lesions within right fronto-parietal networks. We conclude that the newly developed ADL-based neglect battery provides an economic and ecologically valid tool for the assessment of neglect. The test can be used to assess and quantify neglect in everyday activities, and thus to monitor realistically rehabilitative needs of neglect patients. Copyright © 2010 Elsevier Ltd.

    Full Text Available Vehicle-to-grid (V2G and grid-to-vehicle (G2V strategies are considered to help stabilize the electric grid but their true impact on battery degradation is still unknown. The intention of this study is to test the impact of such strategies on the degradation of commercial Li-ion batteries. This first part looks into the preliminary testing performed prior to the start of degradation studies to ensure that the selected cells are compatible. Both the thermodynamic and kinetic cell-to-cell variation within the selected batch and the diagnostic-ability of the cells were investigated. The cells were found to have low cell-to-cell variations and are thus consistent. Moreover, the emulation of the full cell from the half-cell data prepared from harvested electrodes was successful and the degradation forecast showed that the main degradation modes can be differentiated.

    Full Text Available Background: The Movement Assessment Battery for Children - 2nd edition (MABC-2 is used for the assessment of motor proficiency and identification of motor impairments in 3-16 year old children. Although there are some gender differences in the motor development of children, in the MABC-2 test the same tasks and norms are used for both genders. Objective: The aim of the study was to determine gender differences in performance of motor tasks involved in the MABC-2 test in adolescents aged 15 to 16. Methods: Participants (N = 121, 50 boys and 71 girls, mean age 16.0 ± 0.5 years randomly recruited from schools were assessed using the MABC-2 test. The Mann-Whitney U test and effect size r were used to analyse gender differences in performance outcome in the particular motor tasks of the MABC-2 test. Results: As compared to the boys, the girls achieved a significantly shorter time of completion of the unimanual coordination task executed with their preferred hand (p < .001, r = .33 and significantly fewer errors in the graphomotor task (p = .001, r = .29. On the other hand, the boys achieved significantly better results than the girls in the aiming and catching tasks (p ≤ .030, r = .20-.33. Performance in the dynamic balance tasks was not significantly different between genders. The girls demonstrated a significantly longer duration of static balance in one-leg standing as compared to the boys (p = .011, r = .23. For the motor tasks some statistical differences were found, however the effect size of the gender on performance was small or medium. Conclusions: The findings of the study suggest that gender could be a significant factor of performance in the motor tasks associated with object control such as aiming and catching. Other domains, such as manual dexterity and balance, seem to be influenced by gender to a small extent.

    Full Text Available The aim of the present review is to investigate the main field-based tests, used alone or included in sport or fitness batteries, for the assessment of health- and skill-related physical fitness components in adolescents. Different scientific databases were searched through using the selected key words related to physical fitness and its components for adolescence. The search focused on original articles and reviews/meta-analyses using valid, reproducible and feasible tests that fit within the school environment. A total of 100 scientific manuscripts were included in the qualitative synthesis. The present systematic review pointed out 5 fitness tests that well adapt to the evaluation of the components of physical fitness of adolescents within a school environment: the 20 m shuttle run test for cardio-respiratory endurance; the handgrip strength test for upper body maximal strength; the standing broad jump test for lower body maximal strength; the sit-up test to exhaustion for muscular endurance and the 4×10 m shuttle run test for speed, agility and coordination. These fitness tests have been finally selected and incorporated into the Adolescents and Surveillance System for the Obesity prevention – Fitness Test Battery (ASSO-FTB, and will be adopted within the ASSO Project for evaluation purposes. This instrument could be also provided to teachers and people working in schools in order to assess physical fitness of adolescents over time and prevent obesity and related diseases.

    Dry battery on a motorcycle has a rapid rate of voltage drop, life time is not too long, and a long charging time. These are problems for users of dry battery for motorcycle. When the rate in the voltage decreases, the energy storage in the battery is reduced, then at the age of one to two years of battery will be dead and cannot be used, it makes the user should replace the battery. New technology development of a motorcycle battery is lithium ion battery. Lithium ion battery has a specification that has been tested and possible to replace dry battery. Characteristics of lithium ion battery can answer the question on the dry battery service life, the rate of decrease in voltage and charging time. This paper discusses about the technical feasibility for commercialization of lithium ion battery for motorcycle battery. Our proposed methodology of technical feasibility by using a goldsmith commercialization model of the technical feasibility and reconfirm the technical standard using the national standard of motorcycle battery. The battery has been through all the stages of the technical feasibility of the goldsmith model. Based on the results of the study, lithium ion batteries have the minimum technical requirements to be commercialized and has been confirmed in accordance with the standard motorcycle battery. This paper results that the lithium ion battery is visible to commercialized by the technical aspect.

    Many sources of fuel are present aboard current spacecraft, with one especially hazardous source of stored energy: lithium ion batteries. Lithium ion batteries are a very hazardous form of fuel due to their self-sustaining combustion once ignited, for example, by an external heat source. Batteries can become extremely energetic fire sources due to their high density electrochemical energy content that may, under duress, be violently converted to thermal energy and fire in the form of a thermal runaway. Currently, lithium ion batteries are the preferred types of batteries aboard international spacecraft and therefore are routinely installed, collectively forming a potentially devastating fire threat to a spacecraft and its crew. Currently NASA is developing a fine water mist portable fire extinguisher for future use on international spacecraft. As its development ensues, a need for the standard evaluation of various types of fire extinguishers against this potential threat is required to provide an unbiased means of comparing between fire extinguisher technologies and ranking them based on performance.

    2008-01-01

    As a comprehensive and parsimonious theory explaining the socio-psychological mechanism prior to suicidal behavior, strain theory of suicide postulates that conflicting and competing pressures in an individual's life usually precede a suicide. The theory proposes four sources of strain leading to suicide: (1) value strain from conflicting values, (2) aspiration strain from the discrepancy between aspiration and reality, (3) deprivation strain from relative deprivation such as poverty, and (4) coping strain from deficient coping skills in the face of a crisis. This research has content-analyzed 40 suicide notes (20 by suicide completers and 20 by suicide attempters) and found strong support for the strain theory of suicide. Although little difference is found in the number and pattern of strains between the completers and attempters, both groups have many aspirations and coping strains and few value and deprivation strains. Also, the older a suicidal victim is, the more he/she feels deprived and lacks coping skills and feels less bothered with value conflicts. Although the study has offered some support for the new theory, future research with more rigorous quantitative data needs to be conducted to further test the theory on a more comprehensive level.

  15. Automotive Battery Modelling and Management

    Full Text Available The estimation of vehicle battery performance is typically addressed by testing the battery under specific operation conditions by using a model to represent the test results. Approaches for representing test results range from simple statistical models to neural networks to complex, physics-based models. Basing the model on test data could be problematical when testing becomes impractical with many years life time tests. So, real time estimation of battery performance, an important problem in automotive applications, falls into this area. In vehicles it is important to know the state of charge of the batteries in order to prevent vehicle stranding and to ensure that the full range of the vehicle operation is exploited. In this paper, several battery models have studied including analytical, electrical circuits, stochastic and electro- chemical models. Valve Regulated Lead Acid “VRLA” battery has been modelled using electric circuit technique. This model is considered in the proposed Battery Monitoring System “BMS”. The proposed BMS includes data acquisition, data analysis and prediction of battery performance under a hypothetical future loads. Based on these criteria, a microprocessor based BMS prototype had been built and tested in automotive Lab,. The tests show promising results that can be used in industrial applications

    Full Text Available Culture is s common system of believes, values and artifacts that the members of a society use it in their relations, and it transfers from one generation to another. The school culture is a system of norms, meanings and values between school members. One of STD (self-determination theory components is basic psychological needs that emphasizes on Relatedness, Competence and Autonomy to accomplish the motivation. Motivation involves the processes that energize, direct, and sustain behavior. It seems that school culture, basic psychological needs and motivation has immense effect on academic achievement. The purpose of the present research was to examine the relation between students' perceived school culture, basic psychological needs, intrinsic motivation and academic achievement in a causal model. 296 high school students (159 females and 137 males in Tabriz, north - west of Iran, participated in this research and completed the students' perceived school culture questionnaire based on Hofstede's cultural dimensions (femininity, uncertainty avoidance, collectivism and power distance, basic psychological needs and intrinsic motivation. The results of the path analysis showed that fulfillment of basic psychological needs and intrinsic motivation has positive effect on academic achievement. Uncertainty avoidance and power distance have also negative effect on fulfillment of psychological needs, but the influence of femininity on this variable was positive. Also, collectivism has no significant effect on it. In general, the findings showed that if school culture supports students' autonomy, they will experience fulfillment of their basic psychological needs, and attain higher intrinsic motivation and academic achievement.

    Benign rolandic epilepsy (BRE) is a form of partial idiopathic epilepsy according to the International League Against Epilepsy (ILAE) syndromes classification (1989). Recent studies have identified cases of BRE that do not meet the initial definition of 'benign'; these included reports of cases with specific cognitive deficits. It is still a matter of debate, whether these deficits are due to epilepsy per se, to treatment or other associated factors. The aim of this study was to evaluate if BRE children have cognitive deficits at the onset of their seizures, prior to their participation in any anti-epileptic drug therapy (AED). We performed a neuropsychological assessment of 18 BRE children compared with a corresponding age-matched control group. We used the Cambridge Neuropsychological Test Automated Battery (CANTAB). Subjects were at their first neurological evaluation, before any AED therapy. We assessed: visual memory, induction and executive functions. In our group, the BRE children performed comparably with the control children for the induction and executive functions. Substantial differences were identified for the visual memory subtests: PRM percent correct (t = -2.58, p = 0.01) and SRM percent correct (t = -2.73, p = 0.01). Age of seizure onset had a negative impact on the visual memory subtest performances (PRM mean correct latency). We found significant correlations between the different CANTAB subtests results and characteristics of the centrotemporal spikes (CTS). Our results are consistent with the findings of other similar studies. This form of epilepsy is associated with subtle neuropsychological deficits, present at seizure onset. Neuropsychological deficits identified, suggest a more diffuse brain involvement in the epileptiform process.

    The authors tested the component model of reading (CMR) among 186,725 fourth grade students from 38 countries (45 regions) on five continents by analyzing the 2006 Progress in International Reading Literacy Study data using measures of ecological (country, family, school, teacher), psychological, and cognitive components. More than 91% of the differences in student difficulty occurred at the country (61%) and classroom (30%) levels (ecological), with less than 9% at the student level (cognitive and psychological). All three components were negatively associated with reading difficulties: cognitive (student's early literacy skills), ecological (family characteristics [socioeconomic status, number of books at home, and attitudes about reading], school characteristics [school climate and resources]), and psychological (students' attitudes about reading, reading self-concept, and being a girl). These results extend the CMR by demonstrating the importance of multiple levels of factors for reading deficits across diverse cultures.

    This study used a randomized controlled design to test the pathways in basic psychological needs theory, where social relationships characterized by autonomy support, involvement, and structure foster psychological need satisfaction and well-being. Participants were recruited from a physical-activity-based youth program. A new staff training was implemented to manipulate the use of each interpersonal characteristic by program staff (N = 24 observed) and perceptions of each interpersonal characteristic, psychological needs, hope, and self-worth in youth (N = 379 surveyed pre- and postprogram). Staff in the intervention condition used greater overall observed autonomy support, involvement, and structure. Condition assignment did not lead to differences in youth perceptions, but observed staff behaviors positively predicted youth perceptions of staff and perceptions of staff positively predicted change in well-being. Findings indicate that the training manipulated how staff engaged youth, and autonomy support, involvement, and structure are useful strategies to foster well-being in youth.

  20. Evaluation of Batteries for Safe Air Transport

    Full Text Available Lithium-ion batteries are shipped worldwide with many limitations implemented to ensure safety and to prevent loss of cargo. Many of the transportation guidelines focus on new batteries; however, the shipment requirements for used or degraded batteries are less clear. Current international regulations regarding the air transport of lithium-ion batteries are critically reviewed. The pre-shipping tests are outlined and evaluated to assess their ability to fully mitigate risks during battery transport. In particular, the guidelines for shipping second-use batteries are considered. Because the electrochemical state of previously used batteries is inherently different from that of new batteries, additional considerations must be made to evaluate these types of cells. Additional tests are suggested that evaluate the risks of second-use batteries, which may or may not contain incipient faults.

    The purpose of this article was to examine the main and stress-buffering effect relationships between social support and psychological responses to injury. The article presents two studies, both of which matched social support types with injury stressors. Study 1 used measures of stressors, perception of social support availability, and psychological responses of injured athletes. Study 2 utilized measures of stressors, received social support, and psychological responses of injured athletes. During physiotherapy clinic visits, injured athletes (Study 1, N = 319; Study 2, N = 302) completed measures of stressors, social support, and psychological responses to injury. Confirmatory factor analysis (CFA) and moderated hierarchical regression were used to analyse the data. In both studies, CFA suggested adequate model fit for measures of social support and psychological responses to injury. Moderated hierarchical regression analyses in Study 1 revealed significant (p stressors and psychological responses; that is, the relationships between social support, stressors, and psychological responses to sport injury may differ with regard to received or perceived available support. The findings have important implications for the design of social support interventions with injured athletes aimed at alleviating the detrimental effects of injury stressors. What is already known on this subject? The health, social, and sport-injury related research suggests that social support has the potential to moderate (i.e., buffer) those psychological responses to stress that are detrimental to health and well-being. Despite what is a growing body of empirical research that has explored the role of social support in a sport injury context, there has been a paucity of research that has examined how social support functions in relation to injury-related stressors and psychological responses, particularly with regard to the effect of perceived and received support. In addition, there has been

    This report summarizes the work done at Risoe DTU testing a vanadium flow battery as part of the project 'Characterisation of Vanadium Batteries' (ForskEl project 6555) with the partners PA Energy A/S and OI Electric A/S under the Danish PSO energy research program. A 15kW/120kWh vanadium battery has been installed as part of the distributed energy systems experimental facility, SYSLAB, at Risoe DTU. A test programme has been carried out to get hands-on experience with the technology, to characterize the battery from a power system point of view and to assess it with respect to integration of wind energy in the Danish power system. The battery has been in operation for 18 months. During time of operation the battery has not shown signs of degradation of performance. It has a round-trip efficiency at full load of approximately 60% (depending on temperature and SOC). The sources of the losses are power conversion in cell stacks/electrolyte, power converter, and auxiliary power consumption from pumps and controller. The response time for the battery is limited at 20kW/s by the ramp rate of the power converter. The battery can thus provide power and frequency support for the power system. Vanadium battery is a potential technology for storage based services to the power system provided investment and O and M cost are low enough and long term operation is documented. (Author)

    Koretz, Janna; Gutheil, Thomas G

    2009-01-01

    Pathologic hoarding is a symptom generally recognized as related to obsessional dynamics (Gutheil, 1959). The hoarder cannot, without great anxiety, tolerate separation from or dispose of his possessions. Thus the hoarder accumulates vast amount of possessions, often in such amounts as to compromise freedom of movement in the residence. Popular in tabloid reportage, such news items portray persons found dead among floor-to-ceiling piles of old newspapers and similar detritus, while in actual clinical practice such dramatic cases are not common (Bryk, 2005; Duenwald, 2004). More importantly, such individuals are rarely available for psychological intervention or testing, both because of social isolation and injury or death caused by the hoarded materials. Additionally, a majority of the current literature regarding hoarding is linked with Obsessive Compulsive Disorder (OCD), though other major disorders have been noted. This report describes a particular individual with characteristic features of hoarding, which is explored through formal psychological testing.

    Study Design Cross-sectional study. Background Visual rating of postural orientation during functional tasks may be a valuable tool to track rehabilitation progress following anterior cruciate ligament (ACL) injury. A valid test battery assessing postural orientation as a separate construct is lacking. Objectives To evaluate measurement properties of a test battery to assess postural orientation in patients with ACL injury. Methods The content validity of functional tasks was assessed by expert focus group discussions. Fifty-one patients (45% women) with ACL injury performed 9 functional tasks of varying difficulty. Interpretability, internal consistency, interrater reliability, and measurement error were assessed for segment-specific postural orientation errors (POEs), within-task POEs, and total POE score. Postural orientation errors were scored on video on an ordinal scale from 0 (no POEs) to 3 (major POEs). Results Stair ascent, deep squat, and crossover hop for distance were excluded in focus group discussions. Postural orientation errors in some tasks were excluded due to floor effects. The mini-squat and drop jump were excluded due to poor internal consistency (α≤.184). Interrater reliability values for segment-specific POEs and within-task POEs yielded fair to almost perfect agreement (κ = 0.429-0.875) and almost perfect agreement for total POE score (intraclass correlation coefficient = 0.842), without systematic differences between raters. The smallest detectable changes were 0.7 and 5 points for groups and individuals, respectively.

    A major barrier to the widespread dissemination of psychological treatments is the way that therapists are trained. The current method is not scalable. Our objective was to conduct a proof-of-concept study of Web-centered training, a scalable online method for training therapists. The Irish Health Service Executive identified mental health professionals across the country whom it wanted to be trained in a specific psychological treatment for eating disorders. These therapists were given access to a Web-centered training program in transdiagnostic cognitive behavior therapy for eating disorders. The training was accompanied by a scalable form of support consisting of brief encouraging telephone calls from a nonspecialist. The trainee therapists completed a validated measure of therapist competence before and after the training. Of 102 therapists who embarked upon the training program, 86 (84.3%) completed it. There was a substantial increase in their competence scores following the training (mean difference 5.84, 95% Cl -6.62 to -5.05; P<.001) with 42.5% (34/80) scoring above a predetermined cut-point indicative of a good level of competence. Web-centered training proved feasible and acceptable and resulted in a marked increase in therapist competence scores. If these findings are replicated, Web-centered training would provide a means of simultaneously training large numbers of geographically dispersed trainees at low cost, thereby overcoming a major obstacle to the widespread dissemination of psychological treatments.

    Full Text Available To assess the cognition of patients with multiple sclerosis (MS using the Rao's Brief Repeatable Battery of Neuropsychological Tests (BRB-N. METHOD: BRB-N was translated and adapted for control subjects. Subsequently, it was applied to a group of patients with relapsing-remitting (RR MS. RESULTS: The assessment on the healthy controls (n=47 showed that the correlation between tests on the same cognitive domain was high and that there was a five-factor solution that explained 90% of the total variance. Except for the Word List Generation subset of tests, the performance of patients with RRMS (n=39 was worse than that of the healthy controls. CONCLUSION: BRB-N is a relatively simple method to assess cognition of patients with MS in the daily clinic. It does not take long to apply and does not require special skills or equipment.

    Traditional cognitive assessment in neurological conditions involving physical disability is often prevented by the presence of verbal-motor impairment; to date, an extensive motor-verbal-free neuropsychological battery is not available for such purposes. We adapted a set of neuropsychological tests, assessing language, attentional abilities, executive functions and social cognition, for eye-tracking (ET) control, and explored its feasibility in a sample of healthy participants. Thirty healthy subjects performed a neuropsychological assessment, using an ET-based neuropsychological battery, together with standard "paper and pencil" cognitive measures for frontal (Frontal Assessment Battery-FAB) and working memory abilities (Digit Sequencing Task) and for global cognitive efficiency (Montreal Cognitive Assessment-MoCA). Psychological measures of anxiety (State-Trait Anxiety Inventory-Y-STAI-Y) and depression (Beck Depression Inventory-BDI) were also collected, and a usability questionnaire was administered. Significant correlations were observed between the "paper and pencil" screening of working memory abilities and the ET-based neuropsychological measures. The ET-based battery also correlated with the MoCA, while poor correlations were observed with the FAB. Usability aspects were found to be influenced by both working memory abilities and psychological components. The ET-based neuropsychological battery developed could provide an extensive assessment of cognitive functions, allowing participants to perform tasks independently from the integrity of motor or verbal channels. Further studies will be aimed at investigating validity and usability components in neurological populations with motor-verbal impairments.

    Background Down syndrome is associated with specific cognitive deficits. Alongside this, older adults with Down syndrome are a high risk group for dementia. The Arizona Cognitive Test Battery (ACTB), a cognitive assessment battery specifically developed for use with individuals with Down syndrome, has been proposed for use as outcome measures for clinical trials in this population. It has not been validated in older adults with Down syndrome. This study aims to assess the use and validity of the ACTB in older adults with Down syndrome. Methods Participants with Down syndrome aged 45 and over were assessed using the ACTB, standard tabletop tests and informant ratings. Results Assessment outcomes of 49 participants were analysed. Of these, 19 (39%) had a diagnosis of dementia or possible dementia. Most participants were able to attempt most of the tasks, although some tasks had high floor effects (including CANTAB Intra-Extra Dimensional shift stages completed and Modified Dots Task). Of the ACTB tasks, statistically significant differences were observed between the dementia and no dementia groups on CANTAB Simple Reaction Time median latency, NEPSY Visuomotor Precision—Car and Motorbike and CANTAB Paired Associates Learning stages completed. No significant differences were observed for CANTAB Intra-Extra Dimensional Shift, Modified Dots Task, Finger Sequencing, NEPSY Visuomotor precision—Train and Car and CANTAB Paired Associates Learning first trial memory score. Several of the tasks in the ACTB can be used in older adults with Down syndrome and have mild to moderate concurrent validity when compared to tabletop tests and informant ratings, although this varies on a test by test basis. Conclusions Overall, scores for a number of tests in the ACTB were similar when comparing dementia and no dementia groups of older adults with Down syndrome, suggesting that it would not be an appropriate outcome measure of cognitive function for clinical trials of dementia

    The influence of industrial chemicals in the environment is strongly determined by the condition of the soil. Considering the complex interrelationships of soil condition and the specific parameters of the material as influential to bioavailability and decompositional reactions, it is necessary to reproduce various situations via a selected battery of ecotoxicological tests. The use of such batteries has already proved to be suitable for the examination of sediments. In order to make statements about the dangerous potential of chemicals in the soil, samples of natural soil were exposed to industrial chemicals (surfactants, mineral oil hydrocarbons, an antibiotic and a pesticide), and examined regularly in test batteries over a period of four weeks. This microcosm works as a degradation test of environmental relevance, monitoring the effects and reactions of industrial chemicals in natural soil. All test results collected over this period of time come to a very complex and multi-dimensional compilation of data which needs to be considered in full before an assessment is possible. The main goal in analysing the data is to extract the maximum possible information from the matrix. Aside from the graphic presentation, mathematic graphs of the data will be introduced. This method aims to provide a structural and logical relationship to the data, in order to build up a classification system and an order of precedence, which should make it possible to estimate potential risk.

    A revised version of the three-factor theory of child abuse (Lesnik-Oberstein, Cohen, & Koers, 1982) is presented. Further, we report on a research designed to test three main hypotheses derived from Factor I (1) (a high level of hostility in abusive parents) and its sources. The three main hypotheses are: (1) that psychologically abusive mothers have a high level of hostile feelings (Factor I); (2) that the high level of hostile feelings in abusive mothers is associated with low marital coping skills (resulting in affectionless, violent marriages), a negative childhood upbringing (punitive, uncaring, over controlling), a high level of stress (objective stress), and a high level of strain (low self-esteem, depression, neurotic symptoms, social anxiety, feelings of being wronged); and (3) that maternal psychological child abuse is associated with low marital coping skills, a negative childhood upbringing, a high level of stress and a high level of strain. Forty-four psychologically abusing mothers were compared with 128 nonabusing mothers on a variety of measures and were matched for age and educational level. All the mothers had children who were hospitalized for medical symptoms. The three hypotheses were supported, with the exception of the component of hypothesis 2 concerning the association between objective stress and maternal hostility. The positive results are consistent with the three-factor theory.

    The electrolyte of a used lithium-ion battery from a hybrid electric vehicle (HEV) was investigated. The liquid electrolyte was collected through the pressure valve of these 5 Ah cells. It consists of (29.8 ± 0.2) wt.% dimethyl carbonate (DMC), (21.7 ± 0.1) wt.% ethyl methyl carbonate (EMC), (30.3 ± 0.3) wt.% ethylene carbonate (EC) and (2.2 ± 0.1) wt.% cyclohexyl benzene (CHB) which were identified with GC-MS and quantified with GC-FID. Li+ (1.29 ± 0.04) mol L-1 and PF6- were determined with IC as the main ionic species in the solution. Furthermore, BF4- was clearly identified with IC-ESI-MS, IC-ICP-MS and 11B NMR and quantified to a concentration of (120.8 ± 8.3) mg L-1 with ICP-OES. The presence of POF3 (detected with GC-MS), F-, PO2F2-, HPO3F- and H2PO4- (determined with IC-ESI-MS) can be attributed to the reaction of the conducting salt LiPF6 via PF5 with traces of water. HPO3F- and H2PO4- could only be observed in cells which were opened in a laboratory hood under exposure of air humidity. This experiment was done to simulate escaping electrolyte from an HEV battery pack. Furthermore, several alkyl phosphates (identified with GC-MS and IC-ESI-MS) are present in the solution due to further reaction of the different fluorinated phosphates with organic carbonates.

  10. Fear of crime in Belgrade: Testing a socio-demographic and social-psychological factors model

    Full Text Available Despite a wealth of research practice, the conceptualization of fear of crime and the ways in which this fear is measured remain the subject of intense theoretical debate in criminological and sociological disciplines. Taking as a starting point the need for a theoretical explanation of fear of crime and the existing research which has confirmed the relevance of the model which integrates socio-demographic and social-psychological factors, a study was conducted in order to examine the predictive capabilities of these factors and compare the results with those of similar studies in the region. The analysis was based on the data obtained in the course of the regional research project 'Fear of Crime in Large Cities', carried out in 2009 in the capital cities of former Yugoslav republics on a multistage random sample using the method of in-home interview. A hierarchical multiple regression analysis was applied on a sample of 397 adult respondents residing in urban parts of Belgrade in order to draw conclusions on how the variables of the integrated model can help explain the differences in the level of fear of crime. Fear of crime, as a dependent variable, was measured using six vignettes after the reliability and unidimensionality of the construct was confirmed. The results of the regression analysis showed that the proposed model was able to account for 42% of the differences in fear of crime. With regard to the socio-demographic variables (introduced in the first step and accounting for 31% of the variance, it was determined that women express the greatest fear of crime as they avoid being alone in their neighbourhoods at night, visit nearby friends less frequently and believe that the streets, shops, and woods in their immediate surroundings are not safe. Regarding the social-psychological variables (which accounted for the additional 11% of the variance, a higher level of fear was found in persons who believe that other people pose a threat to

  11. Batteries: Overview of Battery Cathodes

    2010-07-12

    The very high theoretical capacity of lithium (3829 mAh/g) provided a compelling rationale from the 1970's onward for development of rechargeable batteries employing the elemental metal as an anode. The realization that some transition metal compounds undergo reductive lithium intercalation reactions reversibly allowed use of these materials as cathodes in these devices, most notably, TiS{sub 2}. Another intercalation compound, LiCoO{sub 2}, was described shortly thereafter but, because it was produced in the discharged state, was not considered to be of interest by battery companies at the time. Due to difficulties with the rechargeability of lithium and related safety concerns, however, alternative anodes were sought. The graphite intercalation compound (GIC) LiC{sub 6} was considered an attractive candidate but the high reactivity with commonly used electrolytic solutions containing organic solvents was recognized as a significant impediment to its use. The development of electrolytes that allowed the formation of a solid electrolyte interface (SEI) on surfaces of the carbon particles was a breakthrough that enabled commercialization of Li-ion batteries. In 1990, Sony announced the first commercial batteries based on a dual Li ion intercalation system. These devices are assembled in the discharged state, so that it is convenient to employ a prelithiated cathode such as LiCoO{sub 2} with the commonly used graphite anode. After charging, the batteries are ready to power devices. The practical realization of high energy density Li-ion batteries revolutionized the portable electronics industry, as evidenced by the widespread market penetration of mobile phones, laptop computers, digital music players, and other lightweight devices since the early 1990s. In 2009, worldwide sales of Li-ion batteries for these applications alone were US$ 7 billion. Furthermore, their performance characteristics (Figure 1) make them attractive for traction applications such as

    Preventive health behaviors, such as regular physical activity and healthy nutrition, are recommended to maintain employability and to facilitate the health of employees. Theory-based workplace health promotion needs to include psychological constructs and consider the motivational readiness (so-called stages of change) of employees. According to the stages, people can be grouped as nonintenders (not motivated to change and not performing the goal behavior), intenders (decided to adopt the goal behavior but not started yet), or actors (performing the goal behavior already). The tailoring to these stages can be done computer based and should make workplace health promotion more effective. It was tested whether a parsimonious computer-based health promotion program implemented at the workplace was effective in terms of lifestyle changes and psychological outcomes as well as body weight. We hypothesized that the stage-matched intervention would outperform the one-size-fits-all active control condition (standard care intervention). In a randomized controlled trial, a total of 1269 employees were recruited by a trained research assistant at their workplace during a routine medical examination. After excluding noneligible employees, 560 completed Time 1 (T1), and 384 also completed Time 2 (T2), achieving a retention rate of 68.6%. Two fully automated computer-based treatments were adopted: (1) an active control condition with information about benefits of exercise and healthy nutrition (n=52), or (2) a stage-matched multiple-behavior intervention that provided different psychological treatments to 9 subgroups, addressing stages of change (nonintenders, intenders, and actors per behavior; n=332). Baseline assessments (T1) on behavior, psychological constructs, and body weight were repeated after 4 weeks (T2). The stage-matched intervention outperformed the active control condition for lifestyle changes containing physical activity and nutrition (χ(2) 1=3.5; P=.04, for N

    Anorexia nervosa (AN) is a psychiatric disease with devastating physical consequences, with a pathophysiological mechanism still to be elucidated. Metagenomic studies on anorexia nervosa have revealed profound gut microbiome perturbations as a possible environmental factor involved in the disease. In this study we performed a comprehensive analysis integrating data on gut microbiota with clinical, anthropometric and psychological traits to gain new insight in the pathophysiology of AN. Fifteen AN women were compared with fifteen age-, sex- and ethnicity-matched healthy controls. AN diet was characterized by a significant lower energy intake, but macronutrient analysis highlighted a restriction only in fats and carbohydrates consumption. Next generation sequencing showed that AN intestinal microbiota was significantly affected at every taxonomic level, showing a significant increase of Enterobacteriaceae, and of the archeon Methanobrevibacter smithii compared with healthy controls. On the contrary, the genera Roseburia, Ruminococcus and Clostridium, were depleted, in line with the observed reduction in AN of total short chain fatty acids, butyrate, and propionate. Butyrate concentrations inversely correlated with anxiety levels, whereas propionate directly correlated with insulin levels and with the relative abundance of Roseburia inulinivorans, a known propionate producer. BMI represented the best predictive value for gut dysbiosis and metabolic alterations, showing a negative correlation with Bacteroides uniformis (microbiota), with alanine aminotransferase (liver function), and with psychopathological scores (obsession-compulsion, anxiety, and depression), and a positive correlation with white blood cells count. In conclusion, our findings corroborate the hypothesis that the gut dysbiosis could take part in the AN neurobiology, in particular in sustaining the persistence of alterations that eventually result in relapses after renourishment and psychological

    1) To report site-specific normative values by age, sex and educational level for four components of the 10/66 Dementia Research Group cognitive test battery; 2) to estimate the main and interactive effects of age, sex, and educational level by site; and 3) to investigate the effect of site by region and by rural or urban location. Population-based cross-sectional one phase catchment area surveys were conducted in Cuba, Dominican Republic, Venezuela, Peru, Mexico, China and India. The protocol included the administration of the Community Screening Instrument for Dementia (CSI 'D', generating the COGSCORE measure of global function), and the Consortium to Establish a Registry for Alzheimer's Disease (CERAD) verbal fluency (VF), word list memory (WLM, immediate recall) and recall (WLR, delayed recall) tests. Only those free of dementia were included in the analysis. Older people, and those with less education performed worse on all four tests. The effect of sex was much smaller and less consistent. There was a considerable effect of site after accounting for compositional differences in age, education and sex. Much of this was accounted for by the effect of region with Chinese participants performing better, and Indian participants worse, than those from Latin America. The effect of region was more prominent for VF and WLM than for COGSCORE and WLR. Cognitive assessment is a basic element for dementia diagnosis. Age- and education-specific norms are required for this purpose, while the effect of gender can probably be ignored. The basis of cultural effects is poorly understood, but our findings serve to emphasise that normative data may not be safely generalised from one population to another with quite different characteristics. The minimal effects of region on COGSCORE and WLR are reassuring with respect to the cross-cultural validity of the 10/66 dementia diagnosis, which uses only these elements of the 10/66 battery.

    Recently emerging evidence suggests that the dominant structural model of mental abilities-the Cattell-Horn-Carroll (CHC) model-may not adequately account for observed scores for mental abilities batteries, leading scholars to call into question the model's validity. Establishing the robustness of these findings is important since CHC is the foundation for several contemporary mental abilities test batteries, such as the Woodcock-Johnson III (WJ-III). Using confirmatory factor analysis, we investigated CHC's robustness across 4 archival samples of mental abilities test battery data, including the WJ-III, the Kaufman Adolescent & Adult Intelligence Test (KAIT), the Kaufman Assessment Battery for Children (KABC), and the Differential Ability Scales (DAS). We computed omega hierarchical (ωH) and omega subscale (ωS) coefficients for g and the broad factors, which estimated the relationship of composite scores to g and the broad factors, respectively. Across all 4 samples, we found strong evidence for a general ability, g. We additionally found evidence for 3 to 9 residualized, orthogonal broad abilities existing independently of g, many of which also explained reliable variance in test battery scores that cannot be accounted for by g alone. The reliabilities of these broad factors, however, were less than desirable (i.e., <.80) and achieving desirable reliabilities would be practically infeasible (e.g., requiring excessively large numbers of subtests). Our results, and those of CHC critics, are wholly consistent with Carroll's model. Essentially, both g and orthogonal broad abilities are required to explain variance in mental abilities test battery scores, which is consistent with Carroll but not Cattell-Horn.

    The International Space Station (ISS) primary Electric Power System (EPS) currently uses Nickel-Hydrogen (Ni-H2) batteries to store electrical energy. The electricity for the space station is generated by its solar arrays, which charge batteries during insolation for subsequent discharge during eclipse. The Ni-H2 batteries are designed to operate at a 35 depth of discharge (DOD) maximum during normal operation in a Low Earth Orbit. Since the oldest of the 48 Ni-H2 battery Orbital Replacement Units (ORUs) has been cycling since September 2006, these batteries are now approaching their end of useful life. In 2010, the ISS Program began the development of Lithium-Ion (Li-Ion) batteries to replace the Ni-H2 batteries and concurrently funded a Li-Ion ORU and cell life testing project. When deployed, they will be the largest Li-Ion batteries ever utilized for a human-rated spacecraft. This paper will include an overview of the ISS Li-Ion battery system architecture, the Li-Ion battery design and development, controls to limit potential hazards from the batteries, and the status of the Li-Ion cell and ORU life cycle testing.

    A model to simulate nickel-cadmium battery performance and response in a spacecraft electrical power system energy balance calculation was developed. The voltage of the battery is given as a function of temperature, operating depth-of-charge (DOD), and battery state-of-charge. Also accounted for is charge inefficiency. A battery is modeled by analysis of the results of a multiparameter battery cycling test at various temperatures and DOD's.

    Full Text Available Battery grouping is a technology widely used to improve the performance of battery packs. In this paper, we propose a time series clustering based battery grouping method. The proposed method utilizes the whole battery charge/discharge sequence for battery grouping. The time sequences are first denoised with a wavelet denoising technique. The similarity matrix is then computed with the dynamic time warping distance, and finally the time series are clustered with the affinity propagation algorithm according to the calculated similarity matrices. The silhouette index is utilized for assessing the performance of the proposed battery grouping method. Test results show that the proposed battery grouping method is effective.

    A formal and complete language assessment requires too much time and also tires the patient out during the first recovery stages after brain injury. The aim of this paper is to introduce a bedside screening, short and sensitive to diagnose aphasias in patients with brain injury. The results of the Bedside Assessment of Language (BAL) was studied in 121 aphasic patients and in 77 dysarthric patients after brain injury. The five linguistic areas assessed in this short battery are: spontaneous language, comprehension, repetition, writing and reading. Each area has a maximum of 5 points, and the test has a total score of 25. Statistics tests used were: median test, Kruskal-Wallis test, Fisher's exact test, receiver operating characteristics curves and correlation coefficient. The BAL showed an excellent internal consistency reliability (Cronbach's alpha coefficient: 0.9419); sensitivity was of 79.3% and specificity of 84.4%. These results indicate that the BAL has been a potentially useful tool for the diagnose of the type of aphasia and it has been sensitive to evolutionary changes in sub-acute stages of language disorders.

    [Purpose] To examine if the SPPB is higher with healthy subjects than outpatients, which was higher than inpatients and if the SPPB can be validated assessment tool for strength tests and lower extremity morphological evaluation in cardiovascular disease patients. [Subjects and Methods] Twenty-four middle aged and older adults with cardiovascular disease were recruited from inpatient and outpatient facilities and assigned to separate experimental groups. Twelve age-matched healthy volunteers were assigned to a control group. SPPB test was used to assess balance and functional motilities. The test outcomes were compared with level of care (inpatient vs. outpatient), physical characteristics, strength and lower extremity morphology. [Results] Total SPPB scores, strength tests (knee extensor muscle strength), and lower extremity morphological evaluation (muscle thickness of anterior and posterior mid-thigh and posterior lower-leg) were greater in healthy subjects and outpatients groups compared with inpatients. To predict total Short Physical Performance Battery scores, the predicted knee extension and anterior mid-thigh muscle thickness were calculated. [Conclusion] The SPPB is an effective tool as the strength tests and lower extremity morphological evaluation for middle-aged and older adult cardiovascular disease patients. Notably, high knee extensor muscle strength and quadriceps femoris muscle thickness are positively associated with high SPPB scores.

    Performance on cognitive tests can be affected by age, education, and also selection bias. We examined the distribution of scores on several cognitive screening tests by age and educational levels in a population-based cohort. An age-stratified random sample of individuals aged 65+ years was drawn from the electoral rolls of an urban US community. Those obtaining age and education-corrected scores > or = 21/30 on the Mini-Mental State Examination (MMSE) were designated as cognitively normal or only mildly impaired, and underwent a full assessment including a battery of neuropsychological tests. Participants were also rated on the Clinical Dementia Rating (CDR) scale. The distribution of neuropsychological test scores within demographic strata, among those receiving a CDR of 0 (no dementia), are reported here as cognitive test norms. After combining individual test scores into cognitive domain composite scores, multiple linear regression models were used to examine associations of cognitive test performance with age and education. In this cognitively normal sample of older adults, younger age and higher education were associated with better performance in all cognitive domains. Age and education together explained 22% of the variation of memory, and less of executive function, language, attention, and visuospatial function. Older age and lesser education are differentially associated with worse neuropsychological test performance in cognitively normal older adult representatives of the community at large. The distribution of scores in these participants can serve as population-based norms for these tests, and can be especially useful to clinicians and researchers assessing older adults outside specialty clinic settings.

  14. Cannabis use and suicidal ideation: Test of the utility of the interpersonal-psychological theory of suicide.

    Despite a documented relationship between cannabis use and suicidality, little is known about psychological vulnerability factors that may increase suicidality among this high-risk group. The Interpersonal-Psychological Theory of Suicide (IPTS; Joiner, 2005) proposes that people are vulnerable to wanting to die by suicide if they experience both perceived burdensomeness and thwarted belongingness. Daily cannabis users may be especially vulnerable to these factors. The current study used moderated mediation to test whether the relation between daily cannabis use status and suicidal ideation (SI) occurred indirectly via higher levels of both perceived burdensomeness and thwarted belongingness among 209 (76.1% female) current cannabis using undergraduates who used cannabis daily (n=39) or less frequently (n=160). The direct effect of cannabis use status on SI was no longer significant after controlling for thwarted belongingness, perceived burdensomeness, and the thwarted belongingness X perceived burdensomeness interaction. Cannabis use status was predictive of greater SI indirectly through perceived burdensomeness only at higher levels of thwarted belongingness. Findings support the utility of the IPTS in regard to SI among daily cannabis users, indicating that difficulties in interpersonal functioning may serve as potential pathways through which daily cannabis use may lead to greater suicide risk.

    From among the few human experimental models that can be used to predict the clinical activity of new anxiolytic drugs, the video-recorded Stroop Color-Word Test (VRSCWT), which uses subjective scales to evaluate anxious states, is notable for its simplicity. However, considering that the choice of treatment for anxiety disorders is heavily dependent on the level of somatic symptomatology, a quantitative evaluation of the physiological alterations elicited by the anxiogenic situation of the VRSCWT would also be of great interest. In the present study, 36 healthy male and female volunteers were submitted to either the VRSCWT or to a nonanxiogenic test. The results showed that, as well as a sensation of anxiety, the VRSCWT elicited increases in heart rate and gastrocnemius tension. Subsequently, a further 48 healthy men and women were randomly assigned to three treatments: placebo, 5 and 10 mg of diazepam, and were submitted to the VRSCWT. The results showed that in men, diazepam blocked the feeling of anxiety elicited by the test, although it did not prevent the physiological alterations, while in women, there was no response to the anxiolytic action of the drug. Taken as a whole, these results suggest that the VRSCWT is an efficient method of inducing anxiety experimentally. It is able to elicit observable psychological and physiological alterations and can detect the blocking, by an anxiolytic, of the feelings of anxiety in healthy men. Furthermore, the results suggest that the neural pathways for the control of the psychological and physiological manifestations of anxiety may be separate. This study also draws attention to the fact that gender is an important variable in the evaluation of anxiolytic drugs.

    LiFeBATT has concentrated its recent testing and evaluation on the safety of its batteries. There appears to be a good margin of safety with respect to overheating of the cells and the cases being utilized for the batteries are specifically designed to dissipate any heat built up during charging. This aspect of LiFeBATT’s products will be even more fully investigated, and assuming ongoing positive results, it will become a major component of marketing efforts for the batteries. LiFeBATT has continued to receive prismatic 20 Amp hour cells from Taiwan. Further testing continues to indicate significant advantages over the previously available 15 Ah cells. Battery packs are being assembled with battery management systems in the Danville facility. Comprehensive tests are underway at Sandia National Laboratory to provide further documentation of the advantages of these 20 Ah cells. The company is pursuing its work with Hybrid Vehicles of Danville to critically evaluate the 20 Ah cells in a hybrid, armored vehicle being developed for military and security applications. Results have been even more encouraging than they were initially. LiFeBATT is expanding its work with several OEM customers to build a worldwide distribution network. These customers include a major automotive consulting group in the U.K., an Australian maker of luxury off-road campers, and a number of makers of E-bikes and scooters. LiFeBATT continues to explore the possibility of working with nations that are woefully short of infrastructure. Negotiations are underway with Siemens to jointly develop a system for using photovoltaic generation and battery storage to supply electricity to communities that are not currently served adequately. The IDA has continued to monitor the progress of LiFeBATT’s work to ensure that all funds are being expended wisely and that matching funds will be generated as promised. The company has also remained current on all obligations for repayment of an IDA loan and lease

    The study is to compare the Modified Physical Performance Test (MPPT) and Short Physical Performance Battery (SPPB) as metrics of mobility and function in older men with peripheral arterial disease (PAD). A total of 51 men (55-87 years) with PAD underwent functional testing including the SPPB, MPPT, Walking Impairment Questionnaire (WIQ), stair ascent, and 6-min walk distance. Individuals were grouped according to SPPB and MPPT scores as not limited on either, limited only on the MPPT, or limited on both. The MPPT identified a higher proportion of patients as being functionally limited than the SPPB (p < 0.001). Men identified as limited only by the MPPT, and not the SPPB, were subsequently confirmed to have lower function on all measures compared to those not identified as limited by either the SPPB or the MPPT (p < 0.02). These findings suggest the MPPT is an appropriate measure to identify early declines in men with PAD and may identify global disability better than SPPB. Implications for rehabilitation Individuals with peripheral arterial disease have low activity levels and are at risk for a loss of independence and global disability. Early detection of decline in mobility and global function would allow for interventions before large changes in ambulatory ability or a loss of functional independence occur. This study shows the Modified Physical Performance Test may be an appropriate test to identify early decline in function in men with peripheral arterial disease.

    Full Text Available Background/Aims: Alzheimer's disease (AD is the most common form of dementia. Neuropsychological assessment of individuals with AD primarily focuses on tests of cortical functioning. However, in clinical practice, the underlying pathologies of dementia are unknown, and a focus on cortical functioning may neglect other domains of cognition, including subcortical and executive functioning. The current study aimed to improve the diagnostic discrimination ability of the Consortium to Establish a Registry for Alzheimer's Disease - Neuropsychological Assessment Battery (CERAD-NAB by adding three tests of executive functioning and mental speed (Trail Making Tests A and B, S-Words. Methods: Logistic regression analyses of 594 normal controls (NC, 326 patients with mild AD and 224 patients with other types of dementia (OD were carried out, and the area under the curve values were compared to those of CERAD-NAB alone. Results: All comparisons except AD-OD (65.5% showed excellent classification rates (NC-AD: 92.7%; NC-OD: 89.0%; NC-all patients: 91.0% and a superior diagnostic accuracy of the extended version. Conclusion: Our findings suggest that these three tests provide a sensible addition to the CERAD-NAB and can improve neuropsychological diagnosis of dementia.

    This study evaluates the extent to which psychological adaptation (validated measures of depressive symptoms, anxiety, and test-specific distress) after genetic susceptibility testing is influenced by changes in beliefs about Alzheimer's disease (AD) and sharing of test results with others. Adult children of AD patients (N=269) from a randomized clinical trial involving genetic testing for apolipoprotein E (APOE) provided information before, as well as 6 weeks and 12 months after results disclosure. The levels of adaptation varied highly among participants at 12-month assessment. Participants who learned that they were ε4 negative (lower risk) had a reduction in perceived risk and concern about developing AD compared with those who learned that they were ε4 positive. Those who received results through an extended educational protocol (three in-person visits) had a larger decline in AD concern than those in a condensed protocol (educational brochure and two in-person visits). Increase in AD concern 6 weeks after disclosure was associated with increase in depression scores (b=0.20, Ppsychological adaptation.

    A robust finding within laboratory research is that structuring information as a test confers benefit on long-term retention-referred to as the testing effect. Although well characterized in laboratory environments, the testing effect has been explored infrequently within ecologically valid contexts. We conducted a series of 3 experiments within a very large introductory college-level course. Experiment 1 examined the impact of required versus optional frequent low-stakes testing (quizzes) on student grades, revealing students were much more likely to take advantage of quizzing if it was a required course component. Experiment 2 implemented a method of evaluating pedagogical intervention within a single course (thereby controlling for instructor bias and student self-selection), which revealed a testing effect. Experiment 3 ruled out additional exposure to information as an explanation for the findings of Experiment 2 and suggested that students at the college level, enrolled in very large sections, accept frequent quizzing well.

Participants were 143 adolescents consecutively admitted to a partial hospitalization program who completed assessments at intake and discharge from the program. Results partially supported the IPTS and suggest that (1) perceived burdensomeness may be an important socially based cognition for understanding concurrent risk for suicidal ideation (SI); (2) thwarted belongingness affects depression symptom severity over time, which indirectly predicts SI over a short follow-up time frame; and (3) the IPTS constructs may function differently in a high-risk clinical adolescent sample, compared to adults, although findings are preliminary. © 2015 The American Association of Suicidology.

    Social cognition is a cognitive domain that is under substantial cultural influence. There are no culturally appropriate standardized tools in India to comprehensively test social cognition. This study describes validation of tools for three social cognition constructs: theory of mind, social perception and attributional bias. Theory of mind tests included adaptations of, (a) two first order tasks [Sally-Anne and Smarties task], (b) two second order tasks [Ice cream van and Missing cookies story], (c) two metaphor-irony tasks and (d) the faux pas recognition test. Internal, Personal, and Situational Attributions Questionnaire (IPSAQ) and Social Cue Recognition Test were adapted to assess attributional bias and social perception, respectively. These tests were first modified to suit the Indian cultural context without changing the constructs to be tested. A panel of experts then rated the tests on likert scales as to (1) whether the modified tasks tested the same construct as in the original and (2) whether they were culturally appropriate. The modified tests were then administered to groups of actively symptomatic and remitted schizophrenia patients as well as healthy comparison subjects. All tests of the Social Cognition Rating Tools in Indian Setting had good content validity and known groups validity. In addition, the social cure recognition test in Indian setting had good internal consistency and concurrent validity. Copyright © 2011 Elsevier B.V. All rights reserved.

Tradicionalmente la atención se ha centrado y se centra sobre las fases que deben regir todo proceso de construcción/adaptación de tests. Estándares internacionalmente aceptados sirven para dirigir este trabajo, y la comunidad científica coincide en la importancia de éstos. No obstante, y más allá de cualquier proceso de construcción/adaptación, el hecho es que el uso de tests es una constante en la investigación psicológica, y una adecuada selección de las pruebas resulta un asunto de vital importancia. Por ello, y esquematizando en primer lugar los criterios que deben guiar la construcción/adaptación de tests, en este estudio teórico se desarrollan unas directrices generales a tener en cuenta a la hora de seleccionar tests para efectuar una investigación psicológica. La información va a presentarse organizada en un total de seis apartados, cada uno de los cuales corresponde a una fase distinta dentro del proceso de creación de tests: a delimitación conceptual del constructo objeto de evaluación; b información sobre la construcción y evaluación cualitativa de ítems; c resultados del análisis estadístico de los ítems; d evidencias empíricas de la estructura interna de la prueba; e resultados de la estimación de la fiabilidad; f evidencias externas de la validez de la puntuaciones. Se finaliza el trabajo reflexionando sobre el alcance de las directrices propuestas y sobre la importancia de seleccionar bajo criterios claros los tests que vayan a usarse en una investigación.

    Depression and anxiety can be a major factor of perioperative stress and might contribute to patients dissatisfaction with medical care if they remain unrecognized. There are several methods to diagnose depression and anxiety like standardized written psychological tests or self report scales. Because these tests are not always suitable for routine use in a busy preadmission test center we evaluated an observer-based rating set for the diagnosis of depression and anxiety. 70 patients of a university hospital preadmission test center were tested with the HADS-D-Test and the observer-based rating set after approval of the institutional review board and written informed consent. Test-data were compared using a logistic regression model and demographic variables were analyzed using t-Test. ANOVA and Pearson correlation. The prevalence of depression in our study population was 11.11% (14.75% in male, 9.76% in female) and the prevalence of anxiety was 7.14% (6.9% in male and 7.32% in female). The correlation between the observer-based rating items and the HADS-D-diagnosis was statistically highly significant. The observer based items "unsteady eye movements" and "general worrisome mood" proved to be especially sensitive for anxiety and the items "sorrowful mood" and "impression of resignation" were sensitive for depression without any influence of the experience of the anesthesiologist. A higher prevalence of depression and anxiety was found in patients with ASA-class III compared to those with ASA-classes I and II while age and type of surgery had no significant influence. Based on our observations depression and anxiety are a relevant factor of preoperative morbidity assessment. Observer-based items are a reliable tool to detect those patients which might need special assistance and therapy in the perioperative period to reduce stress associated with high preexisting levels of depression and anxiety.

    The aim of the present study was to determine the relations between the intelligibility of speech in noise and measures of auditory resolution, loudness recruitment, and cognitive function. The analyses were based on data published earlier as part of the presentation of the Auditory Profile, a test battery implemented in four languages. Tests of the intelligibility of speech, resolution, loudness recruitment, and lexical decision making were measured using headphones in five centers: in Germany, the Netherlands, Sweden, and the United Kingdom. Correlations and stepwise linear regression models were calculated. In sum, 72 hearing-impaired listeners aged 22 to 91 years with a broad range of hearing losses were included in the study. Several significant correlations were found with the intelligibility of speech in noise. Stepwise linear regression analyses showed that pure-tone average, age, spectral and temporal resolution, and loudness recruitment were significant predictors of the intelligibility of speech in fluctuating noise. Complex interrelationships between auditory factors and the intelligibility of speech in noise were revealed using the Auditory Profile data set in four languages. After taking into account the effects of pure-tone average and age, spectral and temporal resolution and loudness recruitment had an added value in the prediction of variation among listeners with respect to the intelligibility of speech in noise. The results of the lexical decision making test were not related to the intelligibility of speech in noise, in the population studied. © The Author(s) 2015.

    Full Text Available The aim of the present study was to determine the relations between the intelligibility of speech in noise and measures of auditory resolution, loudness recruitment, and cognitive function. The analyses were based on data published earlier as part of the presentation of the Auditory Profile, a test battery implemented in four languages. Tests of the intelligibility of speech, resolution, loudness recruitment, and lexical decision making were measured using headphones in five centers: in Germany, the Netherlands, Sweden, and the United Kingdom. Correlations and stepwise linear regression models were calculated. In sum, 72 hearing-impaired listeners aged 22 to 91 years with a broad range of hearing losses were included in the study. Several significant correlations were found with the intelligibility of speech in noise.

    The main aim of the current study was to provide evidence regarding the relationship between emotions communication ability--in terms of emotional intelligence (EI)--and psychological well-being. Additionally, the study explored the moderating effect of sex on this relationship. Participants filled in the Mayer-Salovey-Caruso Emotional Intelligence Test, General Health Questionnaire, Psychological General Well-Being Index, and Depression Questionnaire. Results showed the moderating role of sex in the relationship between EI ability and psychological well-being. Furthermore, the associations between EI and psychological well-being measures were generally higher for men than for women, supporting the idea that sex needs to be taken into account when considering EI measures. The potential helpfulness of EI and emotions communications ability in promoting mental health is discussed.

    While it is difficult to prove that a specific material is causing contamination in a landfill, tests have been conducted at waste-to-energy facilities that indicate that household batteries contribute significant amounts of heavy metals to both air emissions and ash residue. Hennepin County, MN, used a dual approach for developing and implementing a special household battery collection. Alternative collection methods were examined; test collections were conducted. The second phase examined operating and disposal policy issues. This report describes the results of the grant project, moving from a broad examination of the construction and content of batteries, to a description of the pilot collection programs, and ending with a discussion of variables affecting the cost and operation of a comprehensive battery collection program. Three out-of-state companies (PA, NY) were found that accept spent batteries; difficulties in reclaiming household batteries are discussed.

    2015-01-01

    Background Preventive health behaviors, such as regular physical activity and healthy nutrition, are recommended to maintain employability and to facilitate the health of employees. Theory-based workplace health promotion needs to include psychological constructs and consider the motivational readiness (so-called stages of change) of employees. According to the stages, people can be grouped as nonintenders (not motivated to change and not performing the goal behavior), intenders (decided to adopt the goal behavior but not started yet), or actors (performing the goal behavior already). The tailoring to these stages can be done computer based and should make workplace health promotion more effective. Objective It was tested whether a parsimonious computer-based health promotion program implemented at the workplace was effective in terms of lifestyle changes and psychological outcomes as well as body weight. We hypothesized that the stage-matched intervention would outperform the one-size-fits-all active control condition (standard care intervention). Methods In a randomized controlled trial, a total of 1269 employees were recruited by a trained research assistant at their workplace during a routine medical examination. After excluding noneligible employees, 560 completed Time 1 (T1), and 384 also completed Time 2 (T2), achieving a retention rate of 68.6%. Two fully automated computer-based treatments were adopted: (1) an active control condition with information about benefits of exercise and healthy nutrition (n=52), or (2) a stage-matched multiple-behavior intervention that provided different psychological treatments to 9 subgroups, addressing stages of change (nonintenders, intenders, and actors per behavior; n=332). Baseline assessments (T1) on behavior, psychological constructs, and body weight were repeated after 4 weeks (T2). Results The stage-matched intervention outperformed the active control condition for lifestyle changes containing physical activity and

    The Visual Association Test (VAT) is a brief learning task that consists of six line drawings of pairs of interacting objects (association cards). Subjects are asked to name or identify each object and later are presented with one object from the pair (the cue) and asked to name the other (the target). The VAT was administered in a consecutive sample of 174 psychogeriatric day care participants with mild to major neurocognitive disorder. Comparison of test performance with normative data from non-demented subjects revealed that 69% scored within the range of a major deficit (0-8 over two recall trials), 14% a minor, and 17% no deficit (9-10, and ≥10 respectively).VAT-scores correlated with another test of memory function, the Cognitive Screening Test (CST), based on the Short Portable Mental Status Questionnaire (r = 0.53). Tests of executive functioning (Expanded Mental Control Test, Category Fluency, Clock Drawing) did not add significantly to the explanation of variance in VAT-scores.Fifty-five participants (31.6%) were faced with initial problems in naming or identifying one or more objects on the cue cards or association cards. If necessary, naming was aided by the investigator. Initial difficulties in identifying cue objects were associated with lower VAT-scores, but this did not hold for difficulties in identifying target objects.A hierarchical multiple regression analysis was used to examine whether linear or quadratic trends best fitted VAT performance across the range of CST scores. The regression model revealed a linear but not a quadratic trend. The best fitting linear model implied that VAT scores differentiated between CST scores in the lower, as well as in the upper range, indicating the absence of floor and ceiling effects, respectively. Moreover, the VAT compares favourably to word list-learning tasks being more attractive in its presentation of interacting visual objects and cued recall based on incidental learning of the association

    A battery model is developed based on time averaging the current or power, and is shown to be an effective means of predicting the performance of a lead acid battery. The effectiveness of this battery model was tested on battery discharge profiles expected during the operation of an electric vehicle following the various SAE J227a driving schedules. The averaging model predicts the performance of a battery that is periodically charged (regenerated) if the regeneration energy is assumed to be converted to retrievable electrochemical energy on a one-to-one basis.

    The aim of this study was to evaluate and validate the Cambridge Neuropsychological Test Automated Battery (CANTAB) in a Norwegian group of patients undergoing surgery for middle fossa arachnoid cysts (AC). We also wanted to assess health related quality of life (HRQOL) in these patients to see if it could be improved by decompression of the AC. Adult patients (>18 years) with unilateral middle fossa AC and no previous history of neurological disease, head injury, or a psychiatric disorder were eligible for inclusion. We used four tests from CANTAB to assess the level of neuropsychological performance: paired associate learning (PAL) and delayed matching to sample (DMS) assessed temporal lobe functions, while Stockings of Cambridge (SOC) and intra-extra dimensional (IED) shift focused on frontal lobe functions. Patients with postoperative cerebral complications were reported, but excluded from neuropsychological follow-up. In addition to the CANTAB data, pre- and postoperative clinical and radiological data were collected. HRQOL was assessed using Short Form 36 (SF-36) pre- and postoperatively. We found significant improvement in the two temporal tests assessing memory, but no improvement in the two frontal tests assessing executive function. HRQOL was significantly reduced preoperatively in two of eight SF-36 domains and improved significantly in four domains postoperatively. CANTAB facilitates detection of cognitive improvements after decompression of the cyst in patients with AC in the middle fossa. The improvements were detected on the tests sensitive to temporal lobe problems only, not on the tests more sensitive to frontal lobe affection. This establishes construct validity for CANTAB for the first time in this population.

    Computerized neurocognitive assessment tools (NCATS) are often used as a screening tool to identify cognitive deficits after mild traumatic brain injury (mTBI). However, differing methodology across studies renders it difficult to identify a consensus regarding the validity of NCATs. Thus, studies where multiple NCATs are administered in the same sample using the same methodology are warranted. We investigated the validity of four NCATs: the ANAM4, CNS-VS, CogState, and ImPACT. Two NCATs were randomly assigned and a battery of traditional neuropsychological (NP) tests administered to healthy control active duty service members (n = 272) and to service members within 7 days of an mTBI (n = 231). Analyses included correlations between NCAT and the NP test scores to investigate convergent and discriminant validity, and regression analyses to identify the unique variance in NCAT and NP scores attributed to group status. Effect sizes (Cohen's f2) were calculated to guide interpretation of data. Only 37 (0.6%) of the 5,655 correlations calculated between NCATs and NP tests are large (i.e. r ≥ 0.50). The majority of correlations are small (i.e. 0.30 > r ≥ 0.10), with no clear patterns suggestive of convergent or discriminant validity between the NCATs and NP tests. Though there are statistically significant group differences across most NCAT and NP test scores, the unique variance accounted for by group status is minimal (i.e. semipartial R2 ≤ 0.033, 0.024, 0.062, and 0.011 for ANAM4, CNS-VS, CogState, and ImPACT, respectively), with effect sizes indicating small to no meaningful effect. Though the results are not overly promising for the validity of the four NCATs we investigated, traditional methods of investigating psychometric properties may not be appropriate for computerized tests. We offer several conceptual and methodological considerations for future studies regarding the validity of NCATs.

    An ESL nickel-cadmium battery model was extended to match the battery manufacturer's steady state cycling characteristics, and to increase the temperature range over which the model is valid. The model was validated by comparisons with test results in the ambient temperature range 0 to 20 C. Less confidence must be attached to results produced by the model outside the 0 to 20 C range, there being no battery cycling data outside this range with which to judge model performance.

    The objective of this project is research, development and demonstration of innovative thermal management concepts that reduce the cell or battery weight, complexity (component count) and/or cost by at least 20%. The project addresses two issues that are common problems with current state of the art lithium ion battery packs used in vehicles; low power at cold temperatures and reduced battery life when exposed to high temperatures. Typically, battery packs are “oversized” to satisfy the two issues mentioned above. The first phase of the project was spent making a battery pack simulation model using AMEsim software. The battery pack used as a benchmark was from the Fiat 500EV. FCA and NREL provided vehicle data and cell data that allowed an accurate model to be created that matched the electrical and thermal characteristics of the actual battery pack. The second phase involved using the battery model from the first phase and evaluate different thermal management concepts. In the end, a gas injection heat pump system was chosen as the dedicated thermal system to both heat and cool the battery pack. Based on the simulation model. The heat pump system could use 50% less energy to heat the battery pack in -20°C ambient conditions, and by keeping the battery cooler at hot climates, the battery pack size could be reduced by 5% and still meet the warranty requirements. During the final phase, the actual battery pack and heat pump system were installed in a test bench at DENSO to validate the simulation results. Also during this phase, the system was moved to NREL where testing was also done to validate the results. In conclusion, the heat pump system can improve “fuel economy” (for electric vehicle) by 12% average in cold climates. Also, the battery pack size, or capacity, could be reduced 5%, or if pack size is kept constant, the pack life could be increased by two years. Finally, the total battery pack and thermal system cost could be reduced 5% only if the

    Ride-quality experiments similar in objectives, design, and procedure were conducted, one using the U.S. Air Force Total In-Flight Simulator and the other using the Langley Passenger Ride Quality Apparatus to provide the motion environments. Large samples (80 or more per experiment) of test subjects were recruited from the Tidewater Virginia area and asked to rate the comfort (on a 7-point scale) of random aircraft motion typical of that encountered during STOL flights. Test subject characteristics of age, sex, and previous flying history (number of previous airplane flights) were studied in a two by three by three factorial design. Correlations were computed between one dependent measure, the subject's mean comfort rating, and various demographic characteristics, attitudinal variables, and the scores on Spielberger's State-Trait Anxiety Inventory. An effect of sex was found in one of the studies. Males made higher (more uncomfortable) ratings of the ride than females. Age and number of previous flights were not significantly related to comfort ratings. No significant interactions between the variables of age, sex, or previous number of flights were observed.

    Although ethnicity and socioeconomic status (SES) correlate with health inequality, efforts to explain variance in health behavior attributable to these factors are limited by difficulties in population sampling. We used ethnicity identification software to test effects of psychological beliefs about screening as mediators of ethnicity and SES on faecal occult blood colorectal screening behavior in a no-cost health care context. Adults aged 50-67 years (N = 1,678), of whom 28% were from minority South Asian religiolinguistic ethnic groups (Hindu-Gujarati/Hindi, Muslim-Urdu and Sikh-Punjabi), participated in a prospective survey study. Subsequent screening participation was determined from medical records. Screening nonparticipation in the most deprived SES quintile was 1.6 times that of the least deprived quintile. Nonparticipation was 1.6 times higher in South Asians compared with non-Asians. A process model in which psychological variables mediated effects of ethnicity and SES on uptake was tested using structural equation modeling. Self-efficacy and perceived psychological costs of screening were, respectively, positive and negative direct predictors of uptake. Paths from Hindu, Muslim, and Sikh ethnicity, and SES on uptake were fully mediated by lower self-efficacy and higher perceived psychological costs. Paths from South Asian ethnicity to participation via self-efficacy and psychological costs were direct, and indirect via SES. SES is implicated, but does not fully account for low colorectal screening uptake among South Asians. Targeting increased self-efficacy and reduced perceived psychological costs may minimize health inequality effects. Future research should test independent effects of SES and ethnicity on lower self-efficacy and higher psychological costs. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

    In this paper, a pen-on-paper electrochemiluminescence (PoP-ECL) device was entirely hand drawn and written in commercially available crayon and pencil in turn for the first time, and a constant potential-triggered sandwich-type immunosensor was introduced into the PoP-ECL device to form a low-cost ECL immunodevice proof. Each PoP-ECL device contained a hydrophilic paper channel and two PoP electrodes, and the PoP-ECL device was produced as follows: crayon was firstly used to draw hydrophobic regions on pure cellulose paper to create the hydrophilic paper channels followed with a baking treatment, and then a 6B-type black pencil with low resistivity was applied for precision writing, as the PoP electrodes, across the hydrophilic paper channel. For further point-of-care testing, a portable, low-cost rechargeable battery was employed as the power source to provide constant potential to the PoP electrodes to trigger the ECL. Using Carbohydrate antigen 199 as model analyte, this PoP-ECL immunodevice showed a good linear response range from 0.01-200 U mL(-1) with a detection limit of 0.0055 U mL(-1), a high sensitivity and stability. The proposed PoP-ECL immunodevice could be used in point-of-care testing of other tumor markers for remote regions and developing countries. Copyright © 2014 Elsevier B.V. All rights reserved.

    Full Text Available The main objective of the present work is to apply a sliding mode controller (SMC to medium voltage and high power output energy recovery Li-ion power accumulator battery pack testing systems (ERLPABTSs, which are composed of a three-level neutral-point-clamped (NPC three-phase voltage source inverter (VSI and a two-level buck-boost converter without an isolating transformer. An inner current decoupled control scheme for the aforementioned system is proposed and two sliding mode planes for active and reactive current control are designed based on the control scheme. An optimized switching table for current convergence is used according to the error sign of the equivalent input voltage and feedback voltage. The proposed ERLPABTS could be used to integrate discharging energy into the power grid when performing high accuracy current testing. The active and reactive power references for the grid-connected inverter are determined based on the discharging energy from the DC-DC converter. Simulations and experiments on a laboratory hardware platform using a 175 kW insulated gate bipolar transistor (IGBT-based ERLPABTS have been implemented and verified, and the performance is found satisfactory and superior to conventional ERLPABPTS.

    In accordance with Item Response Theory, a computer memory battery with six tests was constructed for use in the Portuguese adult population. A factor analysis was conducted to assess the internal structure of the tests (N = 547 undergraduate students). According to the literature, several confirmatory factor models were evaluated. Results showed better fit of a model with two independent latent variables corresponding to verbal and non-verbal factors, reproducing the initial battery organization. Internal consistency reliability for the six tests were alpha = .72 to .89. IRT analyses (Rasch and partial credit models) yielded good Infit and Outfit measures and high precision for parameter estimation. The potential utility of these memory tasks for psychological research and practice willbe discussed.

    This report summarizes the work done at Risoe-DTU testing a vanadium flow battery as part of the project ''Characterisation of Vanadium Batteries'' (ForskEl project 6555) with the partners PA Energy A/S and OI Electric A/S under the Danish PSO energy research program. A 15kW/120kWh vanadium battery has been installed as part of the distributed energy systems experimental facility, SYSLAB, at Risoe DTU. A test programme has been carried out to get hands-on experience with the technology, to characterize the battery from a power system point of view and to assess it with respect to integration of wind energy in the Danish power system. The battery has been in operation for 18 months. During time of operation the battery has not shown signs of degradation of performance. It has a round-trip efficiency at full load of approximately 60% (depending on temperature and SOC). The sources of the losses are power conversion in cell stacks/electrolyte, power converter, and auxiliary power consumption from pumps and controller. The efficiency was not influenced by the cycling of the battery. The response time for the battery is limited at 20kW/s by the ramp rate of the power converter. The battery can thus provide power and frequency support for the power system. The battery was operated together with a 11kW stall-regulated Gaia wind turbine to smooth the output of the wind turbine and during the tests the battery proved capable of firming the output of the wind turbine. Vanadium battery is a potential technology for storage based services to the power system provided investment and O and M cost are low enough and long term operation is documented. (Author)

    It remains unclear whether the Interpersonal Psychological Theory of Suicide (IPTS; Joiner, ) is generalizable to the population or holds more explanatory power for certain subgroups compared to others. The aim of this study was to (1) identify subgroups of individuals who endorsed suicide ideation in the past month based on a range of mental health and demographic variables, (2) compare levels of the IPTS constructs within these subgroups, and (3) test the IPTS predictions for suicide ideation and suicide attempt for each group. Latent class, negative binomial, linear, and logistic regression analyses were conducted on population-based data obtained from 1,321 adults recruited from Facebook. Among participants reporting suicide ideation, four distinct patterns of risk factors emerged based on age and severity of mental health symptoms. Groups with highly elevated mental health symptoms reported the highest levels of thwarted belongingness and perceived burdensomeness. Tests of the IPTS interactions provided partial support for the theory, primarily in young adults with elevated mental health symptoms. Lack of support found for the IPTS predictions across the subgroups and full sample in this study raise some questions around the broad applicability of the theory. © 2018 The American Association of Suicidology.

    It is well known that public safety workers (PSW) face many stressful situations that yield them as high-risk population for suffering chronic stress diseases. In this multidisciplinary research the cardiac response to induced psychological stress by a short duration Stroop test was evaluated in 20 female and 19 male PSW, in order to compare traditionally used cardiac response parameters with alternative ones. Electrocardiograms have been recorded using the Eindhoven electrodes configuration for 1 min before, 3 min during and 1 min after the test. Signals analysis has been performed for the heart rate and the power spectra of its variability and of the variability of the amplitude of the R-wave, i.e. the highest peak of the electrocardiographic signal periodic sequence. The results demonstrated that the traditional autonomic balance index shows no significant differences between stages. In contrast, the median of the area of the power spectrum of the R-wave amplitude variability in the frequency region dominated by the autonomous nervous system (0.04-to-0.4 Hz) is the more sensitive parameter. Moreover, this parameter allows to identify gender differences consistent with those encountered in other studies.

    Full Text Available Aim. To asses effects of amlodipin and metoprolol on autonomic system in emotional and cold tests in hypertensive patients with different psychological profile (PP Material and methods. 61 patients with arterial hypertension of II grade were observed. Therapy with amlodipin or metoprolol was prescribed and allowed to reach target blood pressure (BP level in all the patients. Patients were divided into 2 groups: 1-st one – patients with normal PP, 2-nd group – patients with subclinical depression. Patients were examined before and 30 days after therapy. Examination included ambulatory BP monitoring, assessment of autonomic status by variational intervalometry and spectral analysis of heart rate variability (HRV in cold and emotional tests. Depression and anxiety levels were determined with Bek’s and HADS scales.  Results. Treatment with amlodipin  and metoprolol can result in improvement, worsening or unchanging of PP.  In hypertensive patients with subclinical depression improving their PP resulted in autonomic reaction change: sympathetic activity increases and reaction on stress becomes more adequate. If subclinical depression occurred in hypertensive patients because of amlodipin and metoprolol therapy, sympathetic system stress-reaction decreased and parasympathetic influence increased. Conclusion. The study results show necessity of psychometric examination of hypertensive patients in order to reveal subclinical depression and anxiety.

    Full Text Available Human resources have nowadays been recognized as one of the most important key competitive advantages of organizations. Human resources management deals with the recruitment, selection and training of the best candidates for a particular job position. Although training has significant influence on the performance of employees, recruitment and selection still remain the crucial steps. The goal of the paper is to explore if special characteristics of candidates for employment in the banking industry could be used for predicting their future success at work. Real-life data from a Croatian bank’s employee database are used for analysis, with the total sample of 1659 candidates tested for the purpose of employment. Results of the multiple regression analysis indicate that the following characteristics are important at forecasting an employee’s success at work in the banking sector: cognitive ability, reasoning, dominance, social boldness, sensitivity, openness to change, warmth, and emotional stability. Therefore, as the best practice for recruitment, the use of the Profile of a Quality Candidate in Banking is proposed.

    A multi-national lab collaborative team was assembled that includes experts from academia and industry to enhance recently developed Computer-Aided Battery Engineering for Electric Drive Vehicles (CAEBAT)-II battery crush modeling tools and to develop microstructure models for electrode design - both computationally efficient. Task 1. The new Multi-Scale Multi-Domain model framework (GH-MSMD) provides 100x to 1,000x computation speed-up in battery electrochemical/thermal simulation while retaining modularity of particles and electrode-, cell-, and pack-level domains. The increased speed enables direct use of the full model in parameter identification. Task 2. Mechanical-electrochemical-thermal (MECT) models for mechanical abuse simulation were simultaneously coupled, enabling simultaneous modeling of electrochemical reactions during the short circuit, when necessary. The interactions between mechanical failure and battery cell performance were studied, and the flexibility of the model for various batteries structures and loading conditions was improved. Model validation is ongoing to compare with test data from Sandia National Laboratories. The ABDT tool was established in ANSYS. Task 3. Microstructural modeling was conducted to enhance next-generation electrode designs. This 3- year project will validate models for a variety of electrodes, complementing Advanced Battery Research programs. Prototype tools have been developed for electrochemical simulation and geometric reconstruction.

    Alzheimer disease (AD) is a genetically heterogenous disorder; in rare cases autosomal dominantly inherited mutations typically cause early-onset familial AD (EOAD), whereas the risk for late-onset AD (LOAD) is generally modulated by genetic variants with relatively low penetrance but high prevalence, with variants in apolipoprotein E (APOE) being a firmly established risk factor. This article presents an overview of the current literature on the psychological and behavioral impact of genetic testing for AD. The few studies available for presymptomatic testing for EOAD showed that only a very small proportion of individuals had poor psychological outcomes as a result. Initial interest in testing for EOAD decreases significantly after identification of a specific mutation in a kindred, suggesting that interest and potential for knowledge may not translate into actual testing uptake. The majority of individuals from both the general population and those with a family history of AD had positive attitudes towards, and were interested in, susceptibility testing for APOE. Motivations for genetic testing included to provide information for future planning and to learn about one's own and one's children's risks of developing AD. Although susceptibility testing for APOE genotype is not currently recommended due to the lack of clinical utility, this review demonstrates that there is interest in testing and no obvious adverse psychological effects to those who have been tested.

    The eco-toxicological approach is based on the determination of the toxic effects on organisms pertaining to various ecosystems and supplies information about the contaminants mixture bioavailability, in complex matrices as sediments. The use of a single species for a correct evaluation of the toxicity levels can be reductive, concerning the complexity of the ecosystem. In this work we have used species with various evolutionary levels and habitats; in particular, three different organisms: two amphipods species (Corophium insidiosum and Gammarus aequicauda) and one bacterium Vibrio fischeri. We have compared these organisms for the evaluation of sediments toxicity in four sites along the Ionian coast (Taranto, Italy); in particular, three sites in Mar Piccolo and one site in Mar Grande. The toxicity of sediments measured using Vibrio fischeri (Microtox Solid Phase Test protocol) has been compared with the mortality of the two amphipods. Both in polluted (Mar Piccolo sites) and in non-polluted environments (Mar Grande), the results of the three biological tests carried out converge into the evaluation of sediments quality monitored. In conclusion, these preliminary results show the potential use of Corophium insidiosum and Gammarus aequicauda as test species for a correct evaluation of sediments quality, together with Vibrio fischeri.

    Civil engineering-related construction and demolition debris is an important source of waste disposed of in municipal solid waste landfills. After clay materials, gypsum waste is the second largest contributor to the residential construction waste stream. As demand for sustainable building practices grows, interest in recovering gypsum waste from construction and demolition debris is increasing, but there is a lack of standardized tests to evaluate the technical and environmental viability of this solid waste recycling process. By recycling gypsum waste, natural deposits of gypsum might be conserved and high amounts of the waste by-product could be reused in the civil construction industry. In this context, this paper investigates a physical property (i.e., resistance to axial compression), the chemical composition and the ecotoxicological potential of ceramic blocks constructed with different proportions of clay, cement and gypsum waste, and assesses the feasibility of using a minimal battery of tests to evaluate the viability of this recycling process. Consideration of the results for the resistance to axial compression tests together with production costs revealed that the best formulation was 35% of plastic clay, 35% of non-plastic clay, 10% of Portland cement and 20% of gypsum waste, which showed a mean resistance of 4.64MPa. Energy dispersive X-ray spectrometry showed calcium and sulfur to be the main elements, while quartz, gypsum, ettringite and nacrite were the main crystalline compounds found in this formulation. Ecotoxicity tests showed that leachate from this formulation is weakly toxic toward daphnids and bacteria (EC(20%)=69.0 and 75.0, respectively), while for algae and fish the leachate samples were not toxic at the EC(50%) level. Overall, these results show that the addition of 20% of gypsum waste to the ceramic blocks could provide a viable substitute for clay in the ceramics industry and the tests applied in this study proved to be a useful tool

    Full Text Available Congenital prosopagnosia, an innate impairment in recognizing faces, as well as the other-race-effect, the disadvantage in recognizing faces of foreign races, both influence face recognition abilities. Here we compared both phenomena by testing three groups: German congenital prosopagnosics (cPs, unimpaired German, and unimpaired South Korean participants (n = 23 per group, on three tests with Caucasian faces. First we ran the Cambridge Face Memory Test (Duchaine & Nakayama, 2006 Neuropsychologia 44 576–585. Participants had to recognize Caucasian target faces in a 3AFC task. German controls performed better than Koreans (p = .009 who performed better than prosopagnosics (p = .0001. Variation of the individual performances was larger for cPs than for Koreans (p = .028. In the second experiment, participants rated the similarity of Caucasian faces (in-house 3D face-database which differed parametrically in features or second order relations (configuration. We found differences between sensitivities to change type (featural or configural, p = 0 and between groups (p = .005 and an interaction between both factors (p = .019. During the third experiment, participants had to learn exemplars of artificial objects (greebles, natural objects (shells, and faces and recognize them among distractors. The results showed an interaction (p = .005 between stimulus type and participant group: cPs where better for non-face stimuli and worse for face stimuli than the other groups. Our results suggest that congenital prosopagnosia and the other-race-effect affect face perception in different ways. The broad range in performance for the cPs directs the focus of our future research towards looking for different forms of congenital prosopagnosia.

    Social anxiety is related to greater suicidality, even after controlling for depression and other psychopathology. The Interpersonal-Psychological Theory of Suicide (IPTS; Joiner, 2005) proposes that people are vulnerable to wanting to die by suicide if they experience both perceived burdensomeness (sense that one is a burden to others) and thwarted belongingness (a greater sense of alienation from others). Socially anxious persons may be especially vulnerable to these interpersonal factors. The current study tested whether interpersonal IPTS components independently and additively mediate the social anxiety-suicidal ideation (SI) relation among 780 (80.5% female) undergraduates. Social anxiety was significantly, robustly related to SI and to thwarted belongingness and perceived burdensomeness. Social anxiety was indirectly related to SI via thwarted belongingness and perceived burdensomeness. The sum of these indirect effects was significant. Moderated mediation analyses indicated that perceived burdensomeness only mediated the relation between social anxiety and SI at higher levels of thwarted belongingness. Findings highlight that difficulties in interpersonal functioning may serve as potential pathways through which social anxiety may lead to greater suicidality.

  14. Shame and Guilt: Relationships of Test of Self-Conscious Affect Measures With Psychological Adjustment and Gender Differences in Iran

    Nima Ghorbani

    2013-06-01

    Full Text Available In numerous studies conducted in Western societies, shame as measured by the Test of Self-Conscious Affect (TOSCA has correlated with maladjustment whereas the TOSCA Guilt Scale has predicted adjustment. The present investigation sought to determine if such linkages would also appear in the Muslim cultural context of Iran. Iranian university students (N = 132 responded to Shame and Guilt Scales from the third version of the TOSCA, along with an array of personality measures. Shame correlated negatively with adjustment and positively with maladjustment. Guilt displayed an opposite pattern of relationships. As in previous Western investigations, women scored higher than men on guilt, but the expected female elevation in shame failed to appear. Shame, nevertheless, interacted with gender to predict relationships with poorer psychological functioning in women, but not in men. These data most importantly confirmed that the TOSCA Shame and Guilt Scales in Iran display implications similar to those observed in the West and that gender differences in Iran may deserve additional research attention.

  15. Fasting and acquired capability for suicide: a test of the interpersonal-psychological theory of suicide in an undergraduate sample.

    2015-03-30

    Though some preliminary research within the framework of the interpersonal-psychological theory of suicide (IPTS; Joiner, 2005) has postulated that restrictive eating may contribute to increased risk for suicide through its effect on the acquired capability for suicide (ACS; i.e., increased fearlessness about death and heightened physical pain tolerance), existing studies have not conducted direct tests of this relationship. To enhance understanding of this relationship, we compared undergraduates who endorsed one form of restrictive eating, fasting, (n = 99) to controls endorsing no forms of eating pathology over the lifetime (n = 94). We hypothesized that the fasting group would have higher ACS and higher likelihood of suicide attempt history. Contrary to hypotheses, no differences emerged between groups on ACS, and frequency of fasting within the fasting group was not significantly associated with ACS. Consistent with hypotheses, the fasting group was more likely to have suicide attempt history. Though results were not entirely consistent with hypotheses, the current study represents the first attempt at isolating and examining one form of restrictive eating (i.e., fasting) within the context of the IPTS. Results suggest that, in isolation, fasting may not be directly contributing to increases in ACS. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

    Durant, R H; Jay, S; Seymore, C

    1990-07-01

    To test a previous theoretical model, we studied the relationships between social, attitude, and psychological factors and adolescent contraceptive behavior over a 6-month period. A pretested questionnaire was administered to a random sample of 115 black females aged 12 to 18 years from a low socioeconomic population. Six months after the initial interview 113 of the subjects were administered a second questionnaire assessing their sexual and contraceptive behavior. Based on regression analysis, previous pregnancy and coital frequency explained 12.7% (p less than or equal to 0.0001) of the variation in engaging in unprotected coitus. When controlling for sexual activity, birth control knowledge and previous broken appointments explained an additional 5.5% of variation in the regression model (total R2 = 0.185). Coital frequency of the subjects was positively associated with Tanner stage, length of the relationship, effectiveness of previous contraceptive method(s), and degree of birth control knowledge. Coital frequency was inversely associated with a negative attitude toward pregnancy and negative parental attitudes toward adolescent pregnancy. The perceived risk of pregnancy was positively correlated with coital frequency and previous pregnancy. These findings support our model, but suggest that among low socioeconomic black female adolescents the interpretation of several model components depends on the subjects' attitude toward pregnancy and her perception of her parent's attitude toward adolescent pregnancy.

    The alteration of the written description of an image scene constitutes an early and sensible indicator in diagnosing the Alzheimer`s disease (AD). Measurements of cerebral blood rates (CBR) by SPECT show characteristic regional anomalies. We have studied correlations between the neuro-psychological tests (NT), parameters of description (description of the image of a thief of crackers) and CBR in patients afflicted by AD. Ten patients afflicted by AD of slow onset (MMSE 20.2{+-} 5.1) were subject to the following NTs: MMSE, Wounded A, Battery of Aphasia, BNT, verbal fluence, gesticulative practice, direct and inversion span, copy of a figure, immediate recall of a figure, immediate recall of a story. The description variables were the length of texts (words, phrases), the items of information, the grammatical, semantic and orthographic errors. The relative variations of CBR were obtained after injection by HMPAO - {sup 99m}Tc. The indices of asymmetry were calculated by the method of the regions of interest and the correlations were calculated between the NTs, description variables and L/R asymmetry by SPECT. For the temporal lobes the correlations are significant with: Battery of Aphasia and BNT (p < 0.01), and recall of a story (p < 0.05); in the anterior frontal lobes with: MMSE and direct span (p < 0.05); in the posterior frontal lobes with: Battery of Aphasia (p < 0.05), BNT and recall of a story (p < 0.01). For writing, the grammatical errors are correlated with the anterior frontal asymmetries (p < 0.03); the semantic errors with the anterior and posterior frontal lobes (p < 0.02) and with the temporal lobes (p < 0.05). Our results show a correlations of the frontal and temporal asymmetries with the early degradation of the scores of written semantic errors and the oral tests of language. The grammatical errors appearing later and in severe forms of AD as the attention abilities are connected only to anterior frontal asymmetries. Different functional

    To study relations between test performance, academic self-esteem, self-reported stress and saliva cortisol levels in students exposed to test demands at school. 46 randomly selected 6th and 9th graders voluntarily participated in an experimental school test concerning reading and mathematics skills. Cortisol saliva samples were collected at awakening, 30 min later, before test and after test. Perceived stress was registered with a visual analogue scale (VAS). A standardized self-rating questionnaire for measuring self-esteem was administered together with questions about school stress and psychological reactions when exposed to stress during a test. Experienced stress during the school test was correlated to low test performance and to low self-rated evaluation of self-esteem as well as to an increase of saliva cortisol levels during the test. There were also correlations between certain psychological reactions to demands and different cortisol measures. Children who reported that they applied the procedure "I say to myself: I can solve this task" in a school test situation had a lower morning increase of saliva cortisol. Reported use of the procedure "I get worried and will have problems solving other tasks too"--when referring to a school test situation--was correlated to an increase in cortisol levels during the test situation. Test performance, academic self-esteem, perceived stress and reactions of the hypothalamus-pituitary-adrenal axis (HPA axis) are highly intertwined. Furthermore, certain school stress psychological reactions to performance demands seem to be related to different cortisol reactions.
