    Emerging adulthood is a period of life transition, in which youths are no longer adolescents but have not yet reached full adulthood. Measuring emerging adulthood is crucial because of its association with psychopathology and risky behaviors such as substance use. Unfortunately, the only validated scale for such measurement has a long format (Inventory of Dimensions of Emerging Adulthood [IDEA]-31 items). This study aimed to test whether a shorter form yields satisfactory results without substantial loss of information among a sample of young Swiss men. Data from the longitudinal Cohort Study on Substance Use Risk Factors were used (N = 5,049). IDEA, adulthood markers (e.g., parenthood or financial independence), and risk factors (i.e., substance use and mental health issues) were assessed. The results showed that an 8-item, short-form scale (IDEA-8) with four factors (experimentation, negativity, identity exploration, and feeling in between) returned satisfactory results, including good psychometric properties, high convergence with the initial scale, and strong empirical validity. This study was a step toward downsizing a measure of emerging adulthood. Indeed, this 8-item short form is a good alternative to the 31-item long form and could be more convenient for surveys with constraints on questionnaire length. Moreover, it should help health care practitioners in identifying at-risk populations to prevent and treat risky behaviors. PMID:24973242

    Lynam, Donald R; Sherman, Emily D; Samuel, Douglas; Miller, Joshua D; Few, Lauren R; Widiger, Thomas A

    2013-12-01

    The Elemental Psychopathy Assessment (EPA) is a 178-item self-report measure designed to assess the basic elements of psychopathy from a Five-Factor Model perspective: Anger, Arrogance, Callousness, Coldness, Disobliged, Distrust, Dominance, Impersistence, Invulnerable, Manipulation, Opposition, Rashness, Self-Assurance, Self-Centered, Self-Contentment, Thrill-Seeking, Unconcern, and Urgency. The present article reports on the development of a short-form version of the EPA in two large undergraduate samples using item response theory. The validity of the resultant, 72-item, item response theory-derived short form is compared against the validity for the full scale in the undergraduate samples and smaller forensic sample. Results indicate that the 18 subscales of the EPA short form remain relatively reliable, possess an internal structure virtually identical to the full version, and manifest highly similar correlational profiles to a variety of criterion measures. The EPA short form is offered as a viable assessment of psychopathy when assessment time is limited. Implications of these findings are discussed. PMID:23996849

  16. Psychometric study of the Persian short-form eight-item Parkinson’s disease questionnaire (PDQ-8) to evaluate health related quality of life (HRQoL)

    PubMed Central

    2014-01-01

    Background To assess validation and reliability of the Persian version of the short-form 8-item Parkinson’s disease questionnaire (PDQ-8) and to compare its psychometric properties with that of the long-form questionnaire (PDQ-39) in order to evaluate the health-related quality of life (HRQoL) in patients with Parkinson’s disease (PD). Methods This cross-sectional study was conducted on 114 non-demented idiopathic PD (IPD) patients consecutively recruited from an outpatient referral movement disorder clinic. Patients were interviewed to fill in the Persian version of PDQ-39 and PDQ-8 questionnaires and clinical examination was performed to measure disease severity indices. Results The Cronbach’s alpha coefficient of the entire PDQ-8 was 0.740 (95% CI: 0.661-0.806). Replacement of PDQ-8 items with other questions with the highest internal consistency within each dimension of the original PDQ-39 did not improve Cronbach’s alpha coefficient [0.723 (95% CI: 0.639-0.794)]. The scores from both PDQ-8 and PDQ-39 had significant correlation with the Hoehn & Yahr (rPDQ-8 = 0.376, rPDQ-39 = 0.442), and Schwab & England (rPDQ-8 = -0.503, rPDQ-39 = -0.598) disease severity scales and disease duration (rPDQ-8 = 0.342, rPDQ-39 = 0.396). Conclusions Persian version of the short-form PDQ (PDQ-8) was shown to be a valid and reliable instrument to assess disease-specific HRQoL in a PD population when used independently. Although the PDQ-8 items were not necessarily those with the highest internal consistency in the components of PDQ-39, they entirely showed proper psychometric properties especially in mental and behavioral aspects. PDQ-8 is a practical and informative instrument in daily clinical practice where clinicians are in shortage of time and when a validated self-reported brief questionnaire is of value. PMID:24885477

  17. Short form Philadelphia Naming Test: Rationale and Empirical Evaluation

    PubMed Central

    Walker, Grant M.; Schwartz, Myrna F.

    2012-01-01

    Purpose To create two matched short forms of the Philadelphia Naming Test (PNT) that yield similar results to the PNT for measuring anomia. Methods Study 1: We first used archived naming data from 94 aphasic individuals to identify which PNT items should be included in the short forms, and the two constructed sets of 30 items, PNT30-A and PNT30-B, were validated using archived data from a separate group of 56 aphasic individuals. Study 2: We then evaluated the reliability of the PNT, PNT30-A, and PNT30-B across independent test administrations with a new group of 25 aphasic individuals selected to represent the full range of naming impairment. Results Study 1: PNT30-A and PNT30-B were found to be internally consistent; and accuracy scores on these subsets of items were highly correlated with the full PNT. Study 2: PNT accuracy was extremely reliable over the span of one week; and independent administrations of PNT30-A and PNT30-B produced similar results to the PNT and to each other. Conclusions The short forms can be used to reliably estimate PNT performance, and the results can be compared to the provided norms. The two matched tests allow for measurement of change in naming ability. PMID:22294412

  18. Use of Both the Short Musculoskeletal Function Assessment Questionnaire and the Short Form-36 among Tibial Fracture Patients was Redundant

    PubMed Central

    2009-01-01

    Objective To compare the Short Musculoskeletal Function Assessment Dysfunction Index and the Short Form-36 Physical Component Summary scores among patients undergoing operative management of tibial fractures. Study Design and Setting Between July 2000 and September 2005, we enrolled 1319 skeletally mature patients with open or closed fractures of the tibial shaft that were managed with intramedullary nailing. Patients were asked to complete the Short Musculoskeletal Function Assessment and Short Form-36 at discharge and 3, 6, and 12 months post surgical fixation. Results Short Musculoskeletal Function Assessment Dysfunction Index and Short Form-36 Physical Component Summary scores were highly correlated at 3, 6, and 12 months post surgical fixation. The difference in mean standardized change scores for the Short Musculoskeletal Function Assessment Dysfunction Index and the Short Form-36 Physical Component Summary, from 3 to 12 months post-surgical fixation, was not statistically significant. Both the Short Musculoskeletal Function Assessment Dysfunction Index and Short Form-36 Physical Component Summary scores were able to discriminate between healed and non-healed tibial fractures at 3, 6, and 12 months post surgery. Conclusion In patients with tibial shaft fractures, the Short Musculoskeletal Function Assessment Dysfunction Index offered no important advantages over the Short Form-36 Physical Component Summary score. These results, along with the usefulness of the Short Form-36 for comparing populations, recommends the Short Form-36 for assessing physical function in studies of patients with tibial fractures.

  19. Investigation of abbreviated 4 and 8 item versions of the PTSD Checklist 5.

    2016-05-30

    Posttraumatic stress disorder (PTSD) is a significant public health concern associated with marked impairment across the lifespan. Exposure to traumatic events alone, however, is insufficient to determine if an individual has PTSD. PTSD is a heterogeneous diagnosis such that assessment of all 20 symptoms is problematic in time-limited treatment settings. Brief assessment tools that identify those at risk for PTSD and measure symptom severity are needed to improve access to care and assess treatment response. The present study evaluated abbreviated measures of PTSD symptoms derived from the PTSD Checklist for DSM-5 (PCL-5) - a 20-item validated measure of PTSD symptoms - across two studies. In the first, using a community sample of adults exposed to a traumatic event, 4-and 8-item versions of the PCL-5 were identified that were highly correlated with the full PCL-5. In the second, using a sample of combat veterans, the 4-and 8-item measures had comparable diagnostic utility to the total-scale PCL-5. These results provide support for an abbreviated measure of the PCL-5 as an alternative to the 20-item total scale. PMID:27137973

  20. A Short Form of the Trauma Symptom Checklist for Children.

    2016-02-01

    The purpose of the current study was to develop a short form (SF) of the Trauma Symptom Checklist for Children (TSCC). The TSCC-SF) maintained 29 items, from the original 54 items, in a sample (N = 215) of sexually abused children who were seeking treatment at a child advocacy center. Exploratory factor analysis refined the original measure, and confirmatory factor analysis provided evidence for best fit for a six-factor, 29-item model. The TSCC-SF evidenced good internal reliability and showed convergent validity with child ratings of post-traumatic stress disorder (PTSD) symptoms obtained from the University of California at Los Angeles PTSD Reaction Index. The TSCC-SF has promise as a shorter assessment measure with sexually abused children in numerous settings, including child advocacy centers and pediatric clinics, where efficient screening and assessment are essential for providing the best standard of care.

    2016-04-01

    This article investigated the accuracy of six short forms of the Dutch Wechsler Preschool and Primary Scale of Intelligence-Third edition (WPPSI-III-NL) in estimating intelligent quotient (IQ) scores in healthy children aged 4 to 7 years (N = 1,037). Overall, accuracy for each short form was studied, comparing IQ equivalences based on the short forms with the original WPPSI-III-NL Full Scale IQ (FSIQ) scores. Next, our sample was divided into three groups: children performing below average, average, or above average, based on the WPPSI-III-NL FSIQ estimates of the original long form, to study the accuracy of WPPSI-III-NL short forms at the tails of the FSIQ distribution. While studying the entire sample, all IQ estimates of the WPPSI-III-NL short forms correlated highly with the FSIQ estimates of the original long form (all rs ≥ .83). Correlations decreased significantly while studying only the tails of the IQ distribution (rs varied between .55 and .83). Furthermore, IQ estimates of the short forms deviated significantly from the FSIQ score of the original long form, when the IQ estimates were based on short forms containing only two subtests. In contrast, unlike the short forms that contained two to four subtests, the Wechsler Abbreviated Scale of Intelligence short form (containing the subtests Vocabulary, Similarities, Block Design, and Matrix Reasoning) and the General Ability Index short form (containing the subtests Vocabulary, Similarities, Comprehension, Block Design, Matrix Reasoning, and Picture Concepts) produced less variations when compared with the original FSIQ score.

  2. Measurement Properties of the Spinal Cord Injury-Functional Index (SCI-FI) Short Forms

    PubMed Central

    Heinemann, Allen W.; Dijkers, Marcel P.; Ni, Pengsheng; Tulsky, David S.; Jette, Alan

    2015-01-01

    Objective To evaluate the psychometric properties of the Spinal Cord Injury Functional Index (SCI-FI) short forms (Basic Mobility, Self-Care, Fine Motor, Ambulation, Manual Wheelchair, and Power Wheelchair) based on internal consistency, correlations between short- and full item bank forms, and a 10-item compute adaptive test version, magnitude of ceiling and floor effects, and test information functions. Design Cross-sectional cohort study. Participants 855 individuals with traumatic spinal cord injury recruited from 6 National Spinal Cord Injury Model Systems facilities. Interventions Not applicable. Main outcome measures SCI-FI full item bank, 10-item computer adaptive test, and parallel short form scores. Results The SCI-FI short forms (with separate versions for individuals with paraplegia and tetraplegia) demonstrate very good internal consistency, group-level reliability, excellent correlations between short forms and scores based on the total item bank, minimal ceiling and floor effects (except ceiling effects for persons with paraplegia on Self-Care, Fine Motor and Power Wheelchair ability, and floor effects for persons with tetraplegia on Self-Care, Fine Motor and Manual Wheelchair ability). The test information functions are acceptable across the range of scores where most persons in the sample performed. Conclusions clinicians and researchers should consider the SCI-FI short forms when computer adaptive testing is not feasible. PMID:24602551

  3. A New Method for Estimating the Variance Overlap between the Short and the Long Form of a Psychological Test

    2015-08-01

    The Wisconsin Schizotypy Scales (WSS) are widely used for assessing schizotypy. Confirmatory factor analysis (CFA) indicates that a two-factor structure, positive and negative schizotypy, underlies these scales. Recently developed 15-item short forms of the WSS demonstrated good reliability and validity. This study examined the factor structure underlying the short-form WSS. Consistent with the original scales, CFA on three large samples (n=6137, 2171, and 2292, respectively) indicated that a two-factor model with positive and negative dimensions provided better fit than a generic schizotypy model for the short-form WSS. The short-form dimensions correlated highly with the original scale dimensions and displayed good stability across 10weeks. Preliminary construct validity was demonstrated through associations with interview and questionnaire measures of psychopathology, functioning, and personality comparable to those found with the original WSS. This is the first study examining the dimensional structure of the short WSS and the validity of these dimensions. The findings support the multidimensional nature of schizotypy and the appropriateness of dimensions derived from the short-form WSS. PMID:26036815

  9. CARDIAC SULFONYLUREA RECEPTOR SHORT FORM-BASED CHANNELS CONFER A GLIBENCLAMIDE-INSENSITIVE KATP ACTIVITY

    PubMed Central

    Pu, Jie-Lin,; Ye, Bin; Kroboth, Stacie L.; McNally, Elizabeth M.; Makielski, Jonathan C.; Shi, Nian-Qing

    2008-01-01

    The cardiac sarcolemmal ATP-sensitive potassium channel (KATP) consists of a Kir6.2 pore and a SUR2 regulatory subunit, which is an ATP-binding cassette (ABC) transporter. KATP channels have been proposed to play protective roles during ischemic preconditioning. A SUR2 mutant mouse was previously generated by disrupting the first nucleotide-binding domain (NBD1), where a glibenclamide action site was located. In the mutant ventricular myocytes, a non-conventional glibenclamide-insensitive (10 μM), ATP-sensitive current (IKATPn) was detected in 33% of single-channel recordings with an average amplitude of 12.3±5.4 pA per patch, an IC50 to ATP inhibition at 10 μM, and a mean burst duration at 20.6±1.8 ms. Newly designed SUR2-isoform or variant-specific antibodies identified novel SUR2 short forms in the sizes of 28 and 68 kDa in addition to a 150-kDa long form in the sarcolemmal membrane of wild-type (WT) heart. We hypothesized that channels constituted by these short forms that lack NBD1, confer IKATPn. The absence of the long form in the mutant corresponded to loss of the conventional glibenclamide-sensitive KATP currents (IKATP) in isolated cardiomyocytes and vascular smooth muscle cells but the SUR2 short forms remained intact. Nested exonic RT-PCR in the mutant indicated that the short forms lacked NBD1 but contained NBD2. The SUR2 short forms co-immunoprecipitated with Kir6.1 or Kir6.2 suggesting that the short forms may function as hemi-transporters reported in other eukaryotic ABC transporter subgroups. Our results indicate that different KATP compositions may co-exist in cardiac sarcolemmal membrane. PMID:18001767

    Larsson, P; John, M T; Hakeberg, M; Nilner, K; List, T

    2014-04-01

    We reported the development and psychometric evaluation of a Swedish 14-item and a five-item short form of the Oral Health Impact Profile. The 14-item version was derived from the English-language short form developed by Slade in1997. The five-item version was derived from the German-language short form developed by John et al. in 2006. Validity, reliability and normative values for the two short form summary scores were determined in a random sample of the adult Swedish population (response rate: 46%, N = 1366 subjects). Subjects with sufficient OHRQoL information to calculate a summary score (N = 1309) were on average 50·1 ± 17.4 years old, and 54% were women. Short form summary scores correlated highly with the 49-item OHIP-S (r ≥ 0.97 for OHIP-S14, r ≥ 0.92 for OHIP-S5) and with self-report of oral health (r ≥ 0.41). Reliability, measured with Cronbach's alpha (0.91 for OHIP-S14, 0.77 for OHIP-S5), was sufficient. In the general population, 50% of the subjects had ≥2 OHIP-S14 score points and 10% had ≥11 points, respectively. Among subjects with their own teeth only and/or fixed dental prostheses and with partial removable dental prostheses, 50% of the population had ≥2 OHIP-S14 score points, and 10% had ≥11 points. For subjects with complete dentures, the corresponding figures were 3 and 24 points. OHIP-S5 medians for subjects in the three population groups were 1, 1 and 2 points. Swedish 14-item and 5-item short forms of the OHIP have sufficient psychometric properties and provide a detailed overview about impaired OHRQoL in Sweden. The norms will serve as reference values for future studies. PMID:24447237

  12. Measuring the phenomenology of autobiographical memory: A short form of the Memory Experiences Questionnaire.

    PubMed

    Luchetti, Martina; Sutin, Angelina R

    2016-01-01

    The Memory Experiences Questionnaire (MEQ) is a theoretically driven and empirically validated 63-item self-report scale designed to measure 10 phenomenological qualities of autobiographical memories: Vividness, Coherence, Accessibility, Time Perspective, Sensory Details, Visual Perspective, Emotional Intensity, Sharing, Distancing and Valence. To develop a short form of the MEQ to use when time is limited, participants from two samples (N = 719; N = 352) retrieved autobiographical memories, rated the phenomenological experience of each memory and completed several scales measuring psychological distress. For each MEQ dimension, the number of items was reduced by one-half based on item content and item-total correlations. Each short-form scale had acceptable internal consistency (median alpha = .79), and, similar to the long-form version of the scales, the new short scales correlated with psychological distress in theoretically meaningful ways. The new short form of the MEQ has similar psychometric proprieties as the original long form and can be used when time is limited. PMID:25894806

    Peyrot, M; Xu, Y; Rubin, R R

    2014-01-01

    Aims To develop and validate a short form of the 54-item Diabetes Medication System Rating Questionnaire that maintains the domains and performance characteristics of the long-form questionnaire. Methods Data from the Diabetes Medication System Rating Questionnaire validation study were analysed to select items representing the nine scales (convenience, negative events, interference, self-monitoring of blood glucose burden, efficacy, social burden, psychological well-being, treatment satisfaction and treatment preference). The resulting 20-item Diabetes Medication System Rating Questionnaire Short-Form was administered online, with validated criterion measures of treatment satisfaction and medication adherence, with a retest within 2 weeks. Participants were US adults (N = 413) with Type 2 diabetes using oral agents alone; insulin by syringe and/or pen with or without oral agents; or glucagon-like peptide-1 agents. Most participants (82%) completed the retest. Results The median inter-item agreement of scales was 0.76 and the total composite (mean of all items except treatment preference) was 0.88. The median test-retest reliability of scales was 0.86, and of the total composite was 0.95. All statistically significant correlations between Diabetes Medication System Rating Questionnaire Short-Form scales and criterion measures of treatment satisfaction and adherence were in the expected direction. The median correlation of the Diabetes Medication System Rating Questionnaire Short-Form with corresponding criterion measures of treatment satisfaction was 0.59; the mean correlation of the same Diabetes Medication System Rating Questionnaire Short-Form measures with adherence was 0.42. The Diabetes Medication System Rating Questionnaire Short-Form scales were more powerful predictors of adherence than were the criterion measures of treatment satisfaction. The Diabetes Medication System Rating Questionnaire Short-Form scales differentiated between those taking different

  14. Validation of a proposed WOMAC short form for patients with hip osteoarthritis

    PubMed Central

    2011-01-01

    Background The aims of this study were to propose a Spanish Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) short form based on previously shortened versions and to study its validity, reliability, and responsiveness for patients with hip osteoarthritis undergoing total hip replacement (THR). Methods Prospective observational study of two independent cohorts (788 and 445 patients, respectively). Patients completed the WOMAC and the Short Form (SF)-36 questionnaires before THR and 6 months afterward. Patients received the questionnaires by mailing, and two reminder letters were sent to patients who had not replied the questionnaire. Based on two studies from the literature, we selected the two shortened domains, the pain domain composed of three items and the function domain composed of eight items. Thus, we proposed an 11-items WOMAC short form. A complete validation process was performed, including confirmatory factor analysis (CFA) and Rasch analysis, and a study of reliability, responsiveness, and agreement measured by the Bland-Altman approach. Results The mean age was about 69 years and about 49% were women. CFA analyses confirmed the two-factor model. The pain and function domains fit the Rasch model. Stability was supported with similar results in both cohorts. Cronbach's alpha coefficients were high, 0.74 and 0.88. The highest correlations in convergent validity were found with the bodily pain and physical function SF-36 domains. Significant differences were found according to different pain and function severity scales, supporting known-groups validity. Responsiveness parameters showed large changes (effect sizes, 2.11 and 2.29). Agreement between the WOMAC long and short forms was adequate. Conclusions Since short questionnaires result in improved patient compliance and response rates, it is very useful to have a shortened WOMAC version with the same good psychometric properties as the original version. The Spanish WOMAC short form

  8. Development of a Short Form of the Five-Factor Narcissism Inventory: the FFNI-SF.

    PubMed

    Sherman, Emily D; Miller, Joshua D; Few, Lauren R; Campbell, W Keith; Widiger, Thomas A; Crego, Cristina; Lynam, Donald R

    2015-09-01

    The Five-Factor Narcissism Inventory (FFNI; Glover, Miller, Lynam, Crego, & Widiger, 2012) is a 148-item self-report inventory of 15 traits designed to assess the basic elements of narcissism from the perspective of a 5-factor model. The FFNI assesses both vulnerable (i.e., cynicism/distrust, need for admiration, reactive anger, and shame) and grandiose (i.e., acclaim seeking, arrogance, authoritativeness, entitlement, exhibitionism, exploitativeness, grandiose fantasies, indifference, lack of empathy, manipulativeness, and thrill seeking) variants of narcissism. The present study reports the development of a short-form version of the FFNI in 4 diverse samples (i.e., 2 undergraduate samples, a sample recruited from MTurk, and a clinical community sample) using item response theory. The validity of the resultant 60-item short form was compared against the validity of the full scale in the 4 samples at both the subscale level and the level of the grandiose and vulnerable composites. Results indicated that the 15 subscales remain relatively reliable, possess a factor structure identical to the structure of the long-form scales, and manifest correlational profiles highly similar to those of the long-form scales in relation to a variety of criterion measures, including basic personality dimensions, other measures of grandiose and vulnerable narcissism, and indicators of externalizing and internalizing psychopathology. Grandiose and vulnerable composites also behave almost identically across the short- and long-form versions. It is concluded that the FFNI-Short Form (FFNI-SF) offers a well-articulated assessment of the basic traits comprising grandiose and vulnerable narcissism, particularly when assessment time is limited.

    Whitehurst, David G. T.; Engel, Lidia; Bryan, Stirling

    2014-01-01

    Context ‘Short Form’ health surveys – such as the SF-36 and SF-12 – are widely used in medical research. Spinal cord injury (SCI) is no exception, despite oft-cited concerns regarding measurement properties for populations with physical impairment. Objective To provide a comprehensive overview of the use of Short Form health surveys and their variants within the SCI literature. Methods Papers published between database inception and September 2012 were identified from 11 electronic databases; a supplementary reference list search was also conducted. Data extraction focused on details regarding the range of different Short Form surveys and variants used in SCI research, the respective frequency of use, the nature of reporting (complete versus partial reporting) and the method of survey administration. Results One hundred seventy-four papers were identified. Thirty-six-item Short Form health surveys were frequently administered as complete instruments (n = 82); in 69 of these 82 studies (84%), it was not clearly stated which 36-item version had been used (e.g. SF-36v1, SF-36v2, RAND-36). Data for individual items and domains were often reported (29% of identified studies), indicating significant partial use of standardized measures. Modified variants of standardized health surveys were administered in 12 studies. Conclusion Although standardized Short Form health surveys are common within SCI research, attempts to add, delete, or modify items have resulted in a number of variants, often with minimal supportive psychometric evidence. Using established, generic outcome measures is appealing for a number of reasons. However, validity is paramount and requires further explicit consideration within the SCI research community.

    2015-01-01

    The reliability and validity of the 8-item Morisky Medication Adherence Scale (MMAS-8) was assessed in a sample of Iranian hypertensive patients. In this multi-center study which lasted from August to October 2014, a total of 200 patients who were suffering from hypertension (HTN) and were taking anti-hypertensive medication(s) were included. The cases were accessed through private and university health centers in the cities of Tehran, Karaj, Kermanshah, and Bafgh in Iran and were interviewed face-to-face by the research team. The validated Persian translation of the MMAS-8 was provided by the owner of this scale. This scale contains 7 questions with "Yes" or "No" response choices and an additional Likert-type question (totally 8 questions). The total score ranges from 0 to 8 with higher scores reflecting better medication adherence. Mean (±SD) overall MMAS-8 score was 5.57 (±1.86). There were 108 (54%), 62 (31%), and 30 (15%) patients in the low, moderate, and high adherence groups. Internal consistency was acceptable with an overall Cronbach's ? coefficient of 0.697 and test-retest reliability showed good reproducibility (r= 0.940); P< 0.001. Overall score of the MMAS-8 was significantly correlated with systolic BP (r= - 0.306) and diastolic BP (r= - 0.279) with P< 0.001 for both BP measurements. The Chi-square test showed a significant relationship between adherence level and BP control (P= 0.016). The sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of the scale were 92.8%, 22.3%, 52.9%, and 76.7%, respectively. The Persian version of the MMAS had acceptable reliability and validity in Iranian hypertensive patients. This scale can be used as a standard and reliable tool in future studies to determine medication adherence of Persian-speaking patients with chronic conditions. PMID:25946926

    Full Wechsler Adult Intelligence Scale-Fourth Edition (WAIS-IV) administration can be time-consuming and may not be necessary when intelligence quotient estimates will suffice. Estimated Full Scale Intelligence Quotient (FSIQ) and General Ability Index (GAI) scores were derived from nine dyadic short forms using individual regression equations based on data from a clinical sample (n = 113) that was then cross validated in a separate clinical sample (n = 50). Derived scores accounted for 70%-83% of the variance in FSIQ and 77%-88% of the variance in GAI. Predicted FSIQs were strongly associated with actual FSIQ (rs = .73-.88), as were predicted and actual GAIs (rs = .80-.93). Each of the nine dyadic short forms of the WAIS-IV was a good predictor of FSIQ and GAI in the validation sample. These data support the validity of WAIS-IV short forms when time is limited or lengthier batteries cannot be tolerated by patients. PMID:26058660

    This study investigated the validity of two- and four-subtest combinations as estimates of WAIS-R Full Scale IQ among clients of low IQ (N = 100). Differences between the short-form means were small and nonsignificant. The correlation between Full Scale IQ and two-subset estimates was .86 and was .92 for the four-subtest estimate. These account for 74% and 85% of the variance, respectively. The two-subtest form correctly classified 69% of the subjects by intelligence category, and the four-subtest form correctly classified 85%. It was concluded the four-subtest form is superior as a screening device when complete administration of the WAIS-R is not feasible. PMID:3980752

    The aim of the present study was to develop a short version of the Time Metaphors Questionnaire (TMQ; Sobol-Kwapinska & Nosal, 2009 ). The original TMQ consists of 95 items and was designed to measure time conceiving. Because completing the TMQ is very time-consuming, this research develops a short form of this questionnaire-Time Metaphors Questionnaire-Short Form (TMQ-SF). A sample of 990 Polish adults completed the TMQ. One-half of the sample was used to construct the TMQ-SF by selecting items based on the exploratory factor analysis. The other half of the sample was used to cross-validate the factorial structure of the TMQ-SF by means of confirmatory factor analysis. The TMQ-SF presented high internal consistency and a clear three-factor structure. The convergent and discriminant validity were assessed based on comparison with the Big Five factors of personality, satisfaction with life, positive and negative affect, time perspective, and mindfulness.

    The reliability and validity of the 8-item Morisky Medication Adherence Scale (MMAS-8) was assessed in a sample of Iranian hypertensive patients. In this multi-center study which lasted from August to October 2014, a total of 200 patients who were suffering from hypertension (HTN) and were taking anti-hypertensive medication(s) were included. The cases were accessed through private and university health centers in the cities of Tehran, Karaj, Kermanshah, and Bafgh in Iran and were interviewed face-to-face by the research team. The validated Persian translation of the MMAS-8 was provided by the owner of this scale. This scale contains 7 questions with “Yes” or “No” response choices and an additional Likert-type question (totally 8 questions). The total score ranges from 0 to 8 with higher scores reflecting better medication adherence. Mean (±SD) overall MMAS-8 score was 5.57 (±1.86). There were 108 (54%), 62 (31%), and 30 (15%) patients in the low, moderate, and high adherence groups. Internal consistency was acceptable with an overall Cronbach’s α coefficient of 0.697 and test–retest reliability showed good reproducibility (r= 0.940); P< 0.001. Overall score of the MMAS-8 was significantly correlated with systolic BP (r= - 0.306) and diastolic BP (r= - 0.279) with P< 0.001 for both BP measurements. The Chi-square test showed a significant relationship between adherence level and BP control (P= 0.016). The sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of the scale were 92.8%, 22.3%, 52.9%, and 76.7%, respectively. The Persian version of the MMAS had acceptable reliability and validity in Iranian hypertensive patients. This scale can be used as a standard and reliable tool in future studies to determine medication adherence of Persian-speaking patients with chronic conditions. PMID:25946926

A meandered on-chip coplanar waveguide is used as the PFL, and CMOS transistor is used as switch in the Cadence Spectre simulation. The circuit sample is fabricated and tested. Pulses of ∼170 ps durations and 120-200 mV amplitudes are obtained when the power supply is tuned from 1.2 V to 2 V. The results show that the traditional PFL based circuit can be implemented in standard CMOS technology for on-chip short pulse generation. Furthermore, the PFL circuits significantly extend the short pulse generation capabilities of CMOS technology. PMID:25933879

    Background The Cognitive Style Questionnaire is a valuable tool for the assessment of hopeless cognitive styles in depression research, with predictive power in longitudinal studies. However, it is very burdensome to administer. Even the short form is still long, and neither this nor the original version exist in validated German translations. Methods The questionnaire was translated from English to German, back-translated and commented on by clinicians. The reliability, factor structure and external validity of an online form of the questionnaire were examined on 214 participants. External validity was measured on a subset of 90 subjects. Results The resulting CSQ-SF-D had good to excellent reliability, both across items and subscales, and similar external validity to the original English version. The internality subscale appeared less robust than other subscales. A detailed analysis of individual item performance suggests that stable results could be achieved with a very short form (CSQ-VSF-D) including only 27 of the 72 items. Conclusions The CSQ-SF-D is a validated and freely distributed translation of the CSQ-SF into German. This should make efficient assessment of cognitive style in German samples more accessible to researchers. PMID:26934499

    The factor structure of the Minnesota Satisfaction Questionnaire short form for nonsupervisory restaurant employees was explored in questions among 2000 employees of three full-service restaurant chains operating in midwestern United States. A total of 2000 surveys were distributed to hourly employees of the three chains. From the mailing, 924 surveys were returned and found useable, a 46.2% response rate. Principal factors analysis identified a four-factor structure for the employees, in contrast to the original two-factor structure, but as in other studies the structure was multifactorial.

    The short form of the Coopersmith Self-Esteem Inventory (SEI) was evaluated for gender bias. The authors replicated a study by L. Francis and D. James (1998) and administered the SEI to 361 middle and high school students (146 boys, 2l5 girls). They found that gender bias existed in 6 of the 25 items on the SEI, with 5 of those items favoring boys. Because recent literature indicates that male and female adolescents experience problems in different areas of their lives, the authors suggest that researchers consider such differences when selecting items for a standardized measure.

    Human actinomycosis is a rare soft tissue infection caused by Gram-positive, anaerobic bacteria Actinomyces israelii, a commensal of the oral cavity. The major clinical forms of actinomycosis are cervicofacial, thoracic, abdominal and pelvic forms. The cervicofacial region is most commonly affected. Actinomycosis is sometimes difficult to diagnose and it should be borne in mind in the differential diagnosis of numerous infectious and non-infectious diseases. We report a patient who came with tooth pain and extra-oral swelling which later on presented as multiple draining sinuses. Our initial suspicion was dento-alveolar abscess or osteomyelitis. However, a culture of the discharge and subsequent biopsy revealed actinomycetes, confirming cervicofacial actinomycosis, but presenting itself not as the typical ‘lumpy jaw’. The patient was successfully treated conservatively with a short but intensive antibiotic course. PMID:23580677

    Purpose Short-form patient-reported outcome measures are popular because they minimize patient burden. We assessed the efficiency of static short forms and computer adaptive testing (CAT) using data from the Patient-Reported Outcomes Measurement Information System (PROMIS) project. Methods We evaluated the 28-item PROMIS depressive symptoms bank. We used post hoc simulations based on the PROMIS calibration sample to compare several short-form selection strategies and the PROMIS CAT to the total item bank score. Results Compared with full-bank scores, all short forms and CAT produced highly correlated scores, but CAT outperformed each static short form in almost all criteria. However, short-form selection strategies performed only marginally worse than CAT. The performance gap observed in static forms was reduced by using a two-stage branching test format. Conclusions Using several polytomous items in a calibrated unidimensional bank to measure depressive symptoms yielded a CAT that provided marginally superior efficiency compared to static short forms. The efficiency of a two-stage semi-adaptive testing strategy was so close to CAT that it warrants further consideration and study. PMID:19941077

    The Five-Factor Borderline Inventory (FFBI) is a 120-item dimensional measure of borderline personality disorder (BPD) that was developed from the description of BPD from the perspective of the Five-Factor Model. The FFBI includes 12 subscales and 1 total score. The current study created a short form of the FFBI (FFBI-SF) using item response theory analyses based on an undergraduate student sample that completed the FFBI. Based on the results, the final FFBI-SF included 48 items, with 4 items per subscale. The construct validity of the short form was compared with the original FFBI in five additional samples. The FFBI-SF showed strong convergence with other BPD scales and comparable convergent and discriminant validity with the FFM compared with the FFBI. The correlational profiles generated by the total score and subscales were highly convergent. Results of the current study suggest that the FFBI-SF may be an accessible and useful assessment tool of BPD. PMID:25882163

    2014-11-01

    The present study developed a revised version of the driving anger expression inventory (25-items) and a short (15-item) version using data from 551 drivers. Split half factor analyses on both versions confirmed the original four factors; personal physical aggressive expression, use of a vehicle to express anger, verbal aggressive expression and adaptive/constructive expression. The two DAX versions were strongly correlated, demonstrating the suitability of both forms of the scale and the aggressive forms of expression were higher for drivers who reported initiating road rage interactions. Total aggressive expression was also higher for drivers who reported recent crash-related conditions, such as: loss of concentration, losing control of their vehicle, moving violations, near-misses and major crashes. The revised DAX and DAX-short provide shorter versions of the 49-item DAX that can more easily be combined with other questionnaires and require smaller sample sizes to analyse. Further research is required to validate these tools among different samples and populations. PMID:25058842

    The Positions on Nursing Diagnosis (PND) is a scale that uses the semantic differential technique to measure nurses' attitudes towards the nursing diagnosis concept. The aim of this study was to develop a shortened form of the Spanish version of this scale and evaluate its psychometric properties and efficiency. A double theoretical-empirical approach was used to obtain a short form of the PND, the PND-7-SV, which would be equivalent to the original. Using a cross-sectional survey design, the reliability (internal consistency and test-retest reliability), construct (exploratory factor analysis, known-groups technique and discriminant validity) and criterion-related validity (concurrent validity), sensitivity to change and efficiency of the PND-7-SV were assessed in a sample of 476 Spanish nursing students. The results endorsed the utility of the PND-7-SV to measure attitudes toward nursing diagnosis in an equivalent manner to the complete form of the scale and in a shorter time. PMID:24601134

  15. The short form of CheA couples chemoreception to CheA phosphorylation.

    1994-01-01

    Escherichia coli cells express two forms of the chemotaxis-associated CheA protein, CheAL and CheAS, as the result of translational initiation at two distinct in-frame initiation sites in the gene cheA. The long form, CheAL, plays a crucial role in chemotactic signal transduction. As a histidine protein kinase, it first autophosphorylates at amino acid His-48; then, it phosphorylates two other chemotaxis proteins, CheY and CheB. The short form, CheAS, lacks the amino-terminal 97 amino acids of CheAL and, therefore, does not contain the site of autophosphorylation. However, it does retain a functional kinase domain. As a consequence, CheAS can mediate transphosphorylation of kinase-deficient CheAL variants. Here we demonstrate in vitro that CheAS also can mediate transphosphorylation of a CheAL variant that lacks the C-terminal segment, a portion of the protein which is thought to interact with CheW and the chemoreceptors. The presence of CheW and the chemoreceptor Tsr enhances this activity and results in modulation of the transphosphorylation rate in response to the Tsr ligand, L-serine. Because CheAS can mediate this activity, it can restore chemotactic ability to Escherichia coli cells that express this truncated CheAL variant. Images PMID:8045878

    The present study used a sample of Chinese adolescents and validated a short-form of the Egna Minnen Beträffande Uppfostran: One's Memories of Upbringing (s-EMBU) assessing perceived parental rearing styles. A Chinese revision of the s-EMBU by the authors was administered to a total of 779 high school students, ages 11 to 19 years. Exploratory factor analysis with half of the sample yielded a three-factor solution of Rejection, Emotional Warmth, and Overprotection, accounting for 47.1% of the total variance onthe father form and 48.8% of the total variance on the mother form. Then, confirmatory factor analysis indicated a good fit of the three-factor model to the data in the other half of the sample. The three subscales consisted of 6, 6, and 7 items, respectively. Scores on these subscales had Cronbach alphas ranging from .71 to .81, indicating adequate internal consistency. These psychometric properties suggest its applicability for research with Chinese adolescents. PMID:22489392

    Effortful control (EC) is an important concept in the research on self-regulation in children. We tested 2 alternative factor models of EC as measured by the Children's Behavior Questionnaire-Very Short Form (CBQ-VSF; Putnam & Rothbart, 2006 ) in a large sample of preschoolers (N = 1,007): 1 lower order and 1 hierarchical second-order structure. Additionally, convergent and predictive validity of EC as measured by the CBQ-VSF were investigated. The results supported a hierarchical model. Moderate convergent validity of the second-order latent EC factor was found in that it correlated with compliance and observed EC tasks. Both CBQ-VSF EC measures were also negatively correlated with child physical aggression. The results have implications for the measurement, modeling, and interpretation of EC applying the CBQ.

    This study examined the incremental validity of the adult short form of the Trait Emotional Intelligence Questionnaire (TEIQue-SF) in predicting 7 construct-relevant criteria beyond the variance explained by the Five-factor model and coping strategies. Additionally, the relative contributions of the questionnaire's 4 subscales were assessed. Two samples of Canadian university students completed the TEIQue-SF, along with measures of the Big Five, coping strategies (Sample 1 only), and emotion-laden criteria. The TEIQue-SF showed consistent incremental effects beyond the Big Five or the Big Five and coping strategies, predicting all 7 criteria examined across the 2 samples. Furthermore, 2 of the 4 TEIQue-SF subscales accounted for the measure's incremental validity. Although the findings provide good support for the validity and utility of the TEIQue-SF, directions for further research are emphasized. PMID:25830494

    Temporal relaxation of density fluctuations in supercooled liquids near the glass transition occurs in multiple steps. Using molecular dynamics simulations for three model glass-forming liquids, we show that the short-time β relaxation is cooperative in nature. Using finite-size scaling analysis, we extract a growing length scale associated with beta relaxation from the observed dependence of the beta relaxation time on the system size. We find, in qualitative agreement with the prediction of the inhomogeneous mode coupling theory, that the temperature dependence of this length scale is the same as that of the length scale that describes the spatial heterogeneity of local dynamics in the long-time α -relaxation regime.

    Objectives There has been little examination of the structural validity of the Parenting Stress Index–Short Form (PSI-SF) for minority populations in clinical contexts in the Unites States. This study aimed to test prespecified factor structures (one-factor, two-factor, and three-factor models) of the PSI-SF. Methods This study used confirmatory factor analysis in a sample of 240 predominantly Black and Latino caregivers of children with behavioral difficulties. Results The three-factor model fit was reasonable, and the criterion validity for the subscale and total scores was good supporting continued cautious use of the PSI-SF for clinical minority populations. Conclusions The PSI-SF could be integrated as part of screening and intake assessment procedures, which could allow social work practitioners to make more informed decisions about treatment planning, as well as facilitate conversations with caregivers around identifying sources of stress and developing healthy coping strategies.

    The purpose of this study is the construction and validation of an Italian Short Form version of the Student–Teacher Relationship Scale (STRS; Fraire et al., 2013). The analyses were conducted on 1256 students and 210 teachers. The STRS is a self-report measure assessing teachers’ perception of the quality of their relationship with students ranging from preschool to third grade. The items were selected from the original Italian adaptation of the regular STRS (Pianta, 2001) through Rasch (1960/1980) analysis, which allowed us to identify a subset of items with proven psychometric properties. The STRS-SF consists of two subscales: Conflict (eight items) and Closeness (six items). Results indicate that the 14-item instrument shows good internal consistency (α>0.80), high correlations with the scales from the regular STRS (r > 0.90) and equivalence across gender. PMID:26167156

    The Social and Emotional Competencies Evaluation Questionnaire-Teacher's version, Short Form (QACSE-P-SF) allows teachers to assess their students' social and emotional competencies, having been designed for program evaluation. Thirty-nine teachers completed the QACSE-P-SF, regarding 657 students (fourth to ninth grades). Factor analyses supported a six-factor structure with acceptable internal consistency. Sex differences were found with teachers reporting girls as having higher scores on Self-Control, Social Awareness, Relationship Skills, and Responsible Decision Making. Developmental differences were also found with fourth-grade students presenting higher levels of Social Awareness and Relationship Skills than older students. The final version of the QACSE-P-SF is composed by 30 items, organized into six scales and less time consuming than the previous version for teachers who need to assess full classes. PMID:27356548

    Objective Experiencing traumatic events in childhood is related to various psychiatric problems in adulthood, and a comprehensive tool for measuring childhood trauma is necessary in this field. This study aimed to examine the psychometric properties, and factor structure of the Korean version of the Early Trauma Inventory Self Report-Short Form (ETISR-SF). ETISR-SF measures the childhood trauma, including physical, and emotional sexual abuse, as well as general traumas. Methods A clinical and nonclinical samples comprising of 97 subjects from a local community, and 207 patients with the ETISR-SF, were assessed. Other tools, including the Childhood Trauma Questionnaire-Short Form (CTQ-SF), the Beck Depression Inventory (BDI), and the Beck Anxiety Inventory (BAI) were used to assess clinical symptoms. Additional data from 69 college students was used to examine the test-retest reliability. Results The original four-factor model was supported by the confirmatory factor analysis scale [χ2 (351, n=304)=3374.025, p<0.001, TLI=0.969, CFI=0.972, RMSEA=0.030]. The ETISR-SF was found to be a reliable instrument (Cronbach's α=0.869). Comparison of the ETISR-SF scores discriminated the clinical group from that of the control group. The measure showed good convergent and divergent validity, in that the scores were correlated higher with the scores on the CTQ-SF (0.691) than with the scores on the BDI or BAI (0.424, 0.397 respectively). The ETISR-SF was found to be temporally stable, showing the moderate to high correlation (0.844). Conclusion These findings suggest that the Korean version of the ETISR-SF appears to be a reliable and valid instrument for the measurement of reported childhood trauma. PMID:22993521

    Stromelysin-1, a member of the matrix metalloendoprotease family, is a zinc protease involved in the degradation of connective tissue in the extracellular matrix. As a step toward determining the structure of this protein, multidimensional heteronuclear NMR experiments have been applied to an inhibited truncated form of human stromelysin-1. Extensive 1H, 13C, and 15N sequential assignments have been obtained with a combination of three- and four-dimensional experiments. On the basis of sequential and short-range NOEs and 13C alpha chemical shifts, two helices have been delineated, spanning residues Asp-111 to Val-127 and Leu-195 to Ser-206. A third helix spanning residues Asp-238 to Gly-247 is characterized by sequential NOEs and 13C alpha chemical shifts, but not short-range NOEs. The lack of the latter NOEs suggests that this helix is either distorted or mobile. Similarly, sequential and interstrand NOEs and 13C alpha chemical shifts characterize a four-stranded beta-sheet with three parallel strands (Arg-100 to Ile-101, Ile-142 to Ala-147, Asp-177 to Asp-181) and one antiparallel strand (Ala-165 to Tyr-168). Two zinc sites have been identified in stromelysin [Salowe et al. (1992) Biochemistry 31, 4535-4540]. The NMR spectral properties, including chemical shift, pH dependence, and proton coupling of the imidazole nitrogens of six histidine residues (151, 166, 179, 201, 205, and 211), invariant in the matrix metalloendoprotease family, suggest that these residues are zinc ligands. NOE data indicate that these histidines form two clusters: one ligates the catalytic zinc (His-201, -205, and -211), and the other ligates a structural zinc (His-151, -166, and -179). Heteronuclear multiple quantum correlated spectra and specific labeling experiments indicate His-151, -179, -201, -205, and -211 are in the N delta 1H tautomer and His-166 is in the N epsilon 2H tautomer.

    The schema concept has had an important role in both early and more recent accounts of psychopathology. Schemas are underlying cognitive structures that are thought to create vulnerability to disorders, because they act as templates for the perception, encoding, storage, and retrieval of information. Recent approaches to the understanding and treatment of personality disorders give schemas particular prominence, and the concept of early maladaptive schemas forms the cornerstone of Young's (1999) schema-focused cognitive therapy. The aim of this paper is to examine the effect of mood on responses to the Young Schema Questionnaire--short form (YSQ-S; Young, 1998). A sample of 50 non-clinical participants completed the YSQ-S on three different occasions: in neutral mood, and following happy and depressed mood inductions. The results of 30 participants with full data sets showed that emotional deprivation and defectiveness scores increased after the depressed mood induction, whereas entitlement scores increased after the happy mood induction. The results are discussed in relation to cognitive theories of vulnerability to psychopathology, and future directions for research are suggested. PMID:15826405

    A stimulus trace may be temporarily retained either actively [i.e., in working memory (WM)] or by the weaker mnemonic process we will call passive short-term memory, in which a given stimulus trace is highly susceptible to "overwriting" by a subsequent stimulus. It has been suggested that WM is the more robust process because it exploits long-term memory (i.e., a current stimulus activates a stored representation of that stimulus, which can then be actively maintained). Recent studies have suggested that monkeys may be unable to store acoustic signals in long-term memory, raising the possibility that they may therefore also lack auditory WM. To explore this possibility, we tested rhesus monkeys on a serial delayed match-to-sample (DMS) task using a small set of sounds presented with ~1-s interstimulus delays. Performance was accurate whenever a match or a nonmatch stimulus followed the sample directly, but it fell precipitously if a single nonmatch stimulus intervened between sample and match. The steep drop in accuracy was found to be due not to passive decay of the sample's trace, but to retroactive interference from the intervening nonmatch stimulus. This "overwriting" effect was far greater than that observed previously in serial DMS with visual stimuli. The results, which accord with the notion that WM relies on long-term memory, indicate that monkeys perform serial DMS in audition remarkably poorly and that whatever success they had on this task depended largely, if not entirely, on the retention of stimulus traces in the passive form of short-term memory.

    The Life Satisfaction Index-version A (LSIA) is a 20-item questionnaire providing a cumulative score acknowledged as a valid index of quality of life. In the present study, an Italian version was produced through validated procedures of repeated back-translations. The final Italian version (LSIA.it) was administered to 90 healthy subjects (55 women; aged 40-65 yr, median 51). Cronbach alpha was 0.74, in agreement with previous studies on English, Greek, and Spanish versions, suggesting satisfactory internal consistency of the scale. Also in agreement with previous studies, factor analysis identified three factors (mood tone, zest for life, and congruence between desired and achieved goals), with eigenvalues of 2.80, 1.72, and 1.34, respectively. Nine of the original 20 items were dropped because of inconsistency with the overall scale and/or because of ambiguous loading onto the extracted factors. The resulting 11-item short form (LSI-11) had alpha = 0.69 and Kaiser-Meyer-Olkin measure of sample adequacy = 0.65. In our sample, the mean score of LSIA.it was almost the same as that previously reported in the literature for LSIA, and the correlation between LSIA and LSI-11 was very high (r = 0.91). In a test-retest trial, the cumulative score of LSI-11 showed a percentage of agreement ranging from 73.9 to 100 and Cohen's k statistic for reliability ranging from 0.51 to 1. The individual items of the LSI-11 presented substantial (k > 0.6) to excellent (k > 0.8) levels of agreement. The responsiveness of LSIA and LSI-11 during a hospital stay for 30 consecutive inpatients for medical rehabilitation programs, as measured by effect size, was 0.57 and 0.63, respectively. The results suggest that (1) the LSIA it has cultural equivalence with the English LSIA and that (2) the 11-item short form of LSIA is not only simpler but also more valid from a psychometric standpoint.

    Short-form Ron (sfRon) is an understudied, alternative isoform of the full-length Ron receptor tyrosine kinase. In contrast to Ron, which has been shown to be an important player in many cancers, little is known about the role of sfRon in cancer pathogenesis. Here we report the striking discovery that sfRon expression is required for development of carcinogen-induced malignant ovarian tumors in mice. We also show that sfRon is expressed in several subtypes of human ovarian cancer including high-grade serous carcinomas, which is in contrast to no detectable expression in healthy ovaries. In addition, we report that introduction of sfRon into OVCAR3 cells resulted in epithelial-to-mesenchymal transition, activation of the PI3K and PDK1 pathway, and inhibition of the MAPK pathway. We demonstrated that sfRon confers an aggressive cancer phenotype in vitro characterized by increased proliferation and migration, and decreased adhesion of ovarian cancer cells. Moreover, the in vivo studies show that OVCAR3 tumors expressing sfRon exhibit significantly more robust growth and spreading to the abdominal cavity when compared with the parental sfRon negative OVCAR3 cells. These data suggest that sfRon plays a significant role in ovarian cancer initiation and progression, and may represent a promising therapeutic target for ovarian cancer treatment. PMID:27551332

    Objective The Young Schema Questionnaire (YSQ) is a self-report measure of early maladaptive schemas and is currently in its third revision; it is available in both long (YSQ-L3) and short (YSQ-S3) forms. The goal of this study was to develop a Korean version of the YSQ-S3 and establish its psychometric properties in a Korean sample. Methods A total of 542 graduate medical students completed the Korean version of the YSQ-S3 and several other psychological scales. A subsample of 308 subjects completed the Korean YSQ-S3 both before and after a 2-year test-retest interval. Correlation, regression, and confirmatory factor analyses were performed on the data. Results The internal consistency of the 90-item Korean YSQ-S3 was 0.97 and that of each schema was acceptable, with Cronbach's alphas ranging from 0.59 to 0.90. The test-retest reliability ranged from 0.46 to 0.65. Every schema showed robust positive correlations with most psychological measures. The confirmatory factor analysis for the 18-factor structure originally proposed by Young, Klosko, and Weishaar (2003) showed that most goodness-of-fit statistics were indicative of a satisfactory fit. Conclusion These findings support the reliability and validity of the Korean version of the YSQ-S3. PMID:26207121

    Recently, scholars have demonstrated the importance of Family Supportive Supervisor Behaviors (FSSB), defined as behaviors exhibited by supervisors that are supportive of employees’ family roles, in relation to health, well-being, and organizational outcomes. FSSB was originally conceptualized as a multidimensional, superordinate construct with four subordinate dimensions assessed with 14 items: emotional support, instrumental support, role modeling behaviors, and creative work-family management. Retaining one item from each dimension, two studies were conducted to support the development and use of a new FSSB-Short Form (FSSB-SF). Study 1 draws on the original data from the FSSB validation study of retail employees to determine if the results using the 14-item measure replicate with the shorter 4-item measure. Using data from a sample of 823 information technology professionals and their 219 supervisors, Study 2 extends the validation of the FSSB-SF to a new sample of professional workers and new outcome variables. Results from multilevel confirmatory factor analyses and multilevel regression analyses provide evidence of construct and criterion-related validity of the FSSB-SF, as it was significantly related to work-family conflict, job satisfaction, turnover intentions, control over work hours, obligation to work when sick, perceived stress, and reports of family time adequacy. We argue that it is important to develop parsimonious measures of work-family specific support to ensure supervisor support for work and family is mainstreamed into organizational research and practice.

    This report examined the factor structure of the Mental Health Continuum-Short Form (MHC-SF) using bifactor analysis to evaluate a general well-being factor and the three group factors that correspond with emotional, social, and psychological well-being. Using a sample of 902 South African psychology students (M age=21.1 yr., SD=2.7), the MHC-SF was examined using confirmatory factor models, (1) a one-factor model conceptualizing well-being as unidimensional, (2) a correlated three-factor model corresponding with Keyes' model, and (3) a bifactor solution with a general well-being factor and three orthogonalized group factors. The bifactor solution fitted the best and evidenced a strong general well-being factor and three comparatively weak residualized group factors. These findings contribute to the literature by facilitating an examination of the strength of a general well-being factor as contrasted with the multidimensional components of emotional, social, and psychological well-being and advance a case for the interpretation of both the general and multidimensional components. The results inform considerations regarding the employ of the scale in statistical procedures such as multiple regression analysis and structural equation modeling. PMID:25730745

RESEARCH DESIGN AND METHODS A 30-item C-DQOLY-SF was administered to 371 adolescents with type 1 diabetes. Exploratory and confirmatory factor analysis, correlation with HbA1c, internal consistency, and test-retest reliability were used to examine the psychometric characteristics of C-DQOLY-SF. RESULTS A 25-item questionnaire with three correlated second-order factor structures best fitted data. Scores on the 25-item C-DQOLY-SF significantly correlated with HbA1c values. Cronbach’s α and ICCs of each scale and subscale ranged from 0.77 to 0.90 and from 0.70 to 0.92, respectively. CONCLUSIONS The C-DQOLY-SF has satisfactory reliability and validity. The C-DQOLY-SF can be conveniently used in clinical settings to assess the quality of life of adolescents with type 1 diabetes. PMID:21788630

    Background The Changes in Outlook Questionnaire (CiOQ) is a self-report instrument designed to measure both positive and negative changes following the experience of severely stressful events. Previous research has focused on the Western context. The aim of this study is to translate the short form of the measure (CiOQ-S) into simplified Chinese and examine its validity and reliability in a sample of Chinese earthquake survivors. Method The English language version of the 10-item CiOQ was translated into simplified Chinese and completed along with other measures in a sample of earthquake survivors (n = 120). Statistical analyses were performed to explore the structure of the simplified Chinese version of CiOQ-S (CiOQ-SCS), its reliability and validity. Results Principal components analysis (PCA) was conducted to test the structure of the CiOQ-SCS. The reliability and convergent validity were also assessed. The CiOQ-SCS demonstrated a similar factor structure to the English version, high internal consistency and convergent validity with measures of posttraumatic stress symptoms, anxiety and depression, coping and social support. Conclusion The data are comparable to those reported for the original version of the instrument indicating that the CiOQ-SCS is a reliable and valid measure assessing positive and negative changes in the aftermath of adversity. However, the sampling method cannot permit us to know how representative our samples were of the earthquake survivor population. PMID:22530984

    Receptor tyrosine kinases (RTKs) have been the subject of intense investigation due to their widespread deregulation in cancer and the prospect of developing targeted therapeutics against these proteins. The Ron RTK has been implicated in tumor aggressiveness and is a developing target for therapy, but its function in tumor progression and metastasis is not fully understood. We examined Ron activity in human breast cancers and found striking predominance of an activated Ron isoform known as short-form Ron (sfRon), whose function in breast tumors has not been explored. We found that sfRon plays a significant role in aggressiveness of breast cancer in vitro and in vivo. sfRon expression was sufficient to convert slow-growing, nonmetastatic tumors into rapidly growing tumors that spontaneously metastasized to liver and bones. Mechanistic studies revealed that sfRon promotes epithelial-mesenchymal transition, invasion, tumor growth, and metastasis through interaction with p85, the regulatory subunit of phosphoinositide 3-kinase (PI3K). Inhibition of PI3K activity, or introduction of a single mutation in the p85 docking site on sfRon, completely eliminated the ability of sfRon to promote tumor growth, invasion, and metastasis. These findings reveal sfRon as an important new player in breast cancer and validate Ron and PI3K as therapeutic targets in this disease. PMID:22207901

    Psychopathy is a personality syndrome comprised of interpersonal, affective, and behavioral features that has emerged as a correlate of intimate partner violence perpetration. One commonly used self-report measure of psychopathy is the Psychopathic Personality Inventory-Short Form. The current study employed a multi-trait, multi-method approach to test convergent and discriminant validity of the measure in partner-violent couples by comparing males’ self-report of psychopathy to the informant report of their female partner (N = 114). It was hypothesized that the female partner-report of the male’s psychopathy would be highly correlated with the male report of his own psychopathy, thus providing evidence for the construct validity and interrater reliability of the PPI-SF. Analyses found that male and female reports were correlated significantly on the two major factors of the PPI-SF. Furthermore, the female-report explained a significant amount of variance over and above men’s self-report on PAI scales designed to indicate antisocial personality traits. PMID:26213500

    Background: This study was aimed to assess agreement and diagnostic accuracy of the Iranian version of Mini Nutritional Assessment short-form (MNA-SF) against the original MNA, as a gold standard in community-dwelling elderly. Methods: The full MNA and 9-item MNA-SF comprising questions regarding clinical status, dietary assessment and self-perception of health status and nutri-tion together with mid-arm and calf circumference measurements without in-cluding the body mass index (BMI) were completed for 205 volunteers aged 65 or older recruited from all over Markazi Province (Iran). Correlation, diagnostic accuracy and agreement between the MNA-SF and full MNA were calculated. Results: The MNA and the MNA-SF classified 45.4% and 64.4% of the sub-jects as malnourished or at risk of malnutrition, respectively. Substantial agree-ment between the MNA-SF and full MNA was observed (Kappa=0.633). The MNA-SF correlated strongly with the full MNA (r=0.868, P<0.001). The MNA-SF showed high sensitivity (96.77%) and negative predictive values (95.89%), relatively high specificity (62.5%) and positive predictive values (68.18%) and fair accuracy (Area under curve =0.796). Conclusion: Iranian MNA-SF seems to be an applicable screening tool for quick detection of malnutrition or at risk of malnutrition in community-dwelling elderly especially when BMI is unavailable.

    In the latest (fifth) edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), Internet Gaming Disorder (IGD) was included as a tentative disorder worthy of future research. Since then, several psychometric instruments to assess IGD have emerged in the literature, including the nine-item Internet Gaming Disorder Scale-Short-Form (IGDS9-SF), the most brief tool available to date. Research on the effects of IGD in Portugal has been minimal and may be due to the lack of a psychometrically validated tool to assess this construct within this particular cultural background. Therefore, the aim of the present study was to develop and examine the psychometric properties of the Portuguese IGDS9-SF. A total of 509 adolescents were recruited to the present study. Construct validity of the IGDS9-SF was assessed in two ways. First, confirmatory factor analysis was performed to investigate the factorial structure of the IGDS9-SF in the sample, and the unidimensional structure of the IGDS9-SF fitted the data well. Second, nomological validation of the IGDS9-SF was carried out and the nomological network analyzed was replicated as expected, further supporting the construct validity of the IGDS9-SF. Criterion validity of the IGDS9-SF was also established using key criterion variables. Finally, the IGDS9-SF also showed satisfactory levels of reliability using several indicators of internal consistency. Based on the results found, the IGDS9-SF appears to be a valid and reliable instrument to assess IGD among Portuguese adolescents and further research on IGD in Portugal is warranted. PMID:26974853

  4. Merging binary black holes formed through chemically homogeneous evolution in short-period stellar binaries

    We explore a newly proposed channel to create binary black holes of stellar origin. This scenario applies to massive, tight binaries where mixing induced by rotation and tides transports the products of hydrogen burning throughout the stellar envelopes. This slowly enriches the entire star with helium, preventing the build-up of an internal chemical gradient. The stars remain compact as they evolve nearly chemically homogeneously, eventually forming two black holes, which we estimate typically merge 4-11 Gyr after formation. Like other proposed channels, this evolutionary pathway suffers from significant theoretical uncertainties, but could be constrained in the near future by data from advanced ground-based gravitational-wave detectors. We perform Monte Carlo simulations of the expected merger rate over cosmic time to explore the implications and uncertainties. Our default model for this channel yields a local binary black hole merger rate of about 10 Gpc-3 yr-1 at redshift z = 0, peaking at twice this rate at z = 0.5. This means that this channel is competitive, in terms of expected rates, with the conventional formation scenarios that involve a common-envelope phase during isolated binary evolution or dynamical interaction in a dense cluster. The events from this channel may be distinguished by the preference for nearly equal-mass components and high masses, with typical total masses between 50 and 110 M⊙. Unlike the conventional isolated binary evolution scenario that involves shrinkage of the orbit during a common-envelope phase, short time delays are unlikely for this channel, implying that we do not expect mergers at high redshift.

    Health-related quality of life (HRQoL) is an important indicator of health status and the Short Form-36 (SF-36) is a generic instrument to measure it. Multiple linear regression (MLR) is often used to study the relationship of HRQoL with patients' characteristics, though HRQoL outcomes tend to be not normally distributed, skewed and bounded (e.g. between 0 and 100). A sample of 193 patients with eating disorders has been analysed to assess the performance of the MLR under non-normality conditions. Normal distribution was rejected for seven out of the eight domains. A beta-binomial distribution is suggested to fit the SF-36 scores. The beta-binomial distribution is not rejected for five out of the eight domains. Thus, a beta-binomial regression (BBR) is suggested to analyse the SF-36 scores. Results using MLR and BBR have been compared for real and simulated data. Performance of the BBR is shown to be better than MLR in the HRQoL domains with few ordered categories and very similar to MLR in the more continuous domains. Moreover, the interpretation of the estimates obtained with BBR is clinically more meaningful. A common technique of statistical analysis is preferable for all the HRQoL dimensions. Therefore, the BBR approach is recommended not only to detect significant predictors of HRQoL when SF-36 is used, but also to analyse and interpret the effect of several explanatory variables on HRQoL. Further work is required to test the better performance of BBR against standard methods for other HRQoL outcomes, populations or interventions. PMID:16795124

    Identifying barriers to long-term adherence to reduced energy intake and increased physical activity level is critically important for obese patients seeking weight loss treatment. Previous research has identified that one such barrier is low eating self-efficacy or poor confidence in one's ability to control eating behavior in the presence of challenging situations. Accordingly, a valid, brief measure of eating self-efficacy for longitudinal assessment of weight loss and regain is needed. The purpose of this study was to test the internal consistency and clinical validity of the Weight Efficacy Lifestyle Questionnaire-Short Form (WEL-SF). Participants were 1740 consecutive obese patients who presented for a psychological evaluation in consideration for bariatric surgery. Median BMI was 44.9 (range: 35.0-111.9), age 48.7years (range: 18.9-77.3years), and patients were predominantly female (71.1%) and Caucasian (90.8%). The median WEL-SF total score was 56 (range: 0-80) and Cronbach's alpha measuring internal consistency was 0.92 with a one-factor structure. In terms of clinical validation, lower WEL-SF total scores were significantly associated with higher rates of binge eating episodes (P<0.0001), food addiction severity and dependence (P<0.0001), night eating syndrome (P<0.0001), depression (P<0.0001), and anxiety (P<0.0001). In contrast, higher WEL-SF total scores were associated with higher weight management self-efficacy (P<0.0001) and motivation to make positive lifestyle changes (P<0.0001). Taken together, these findings suggest that the WEL-SF is a psychometrically valid clinically meaningful measure of eating self-efficacy. PMID:26042918

    Purpose: The 65-item Functional Performance Inventory (FPI), developed to quantify functional performance in patients with chronic obstructive pulmonary disease (COPD), has been shown to be reliable and valid. The purpose of this study was to create a shorter version of the FPI while preserving the integrity and psychometric properties of the original. Patients and methods: Secondary analyses were performed on qualitative and quantitative data used to develop and validate the FPI long form. Seventeen men and women with COPD participated in the qualitative work, while 154 took part in the mail survey; 54 completed 2-week reproducibility assessment, and 40 relatives contributed validation data. Following a systematic process of item reduction, performance properties of the 32-item short form (FPI-SF) were examined. Results: The FPI-SF was internally consistent (total scale α = 0.93; subscales: 0.76–0.89) and reproducible (r = 0.88; subscales: 0.69–0.86). Validity was maintained, with significant (P < 0.001) correlations between the FPI-SF and the Functional Status Questionnaire (activities of daily living, r = 0.71; instrumental activities of daily living, r = 0.73), Duke Activity Status Index (r = 0.65), Bronchitis-Emphysema Symptom Checklist (r = −0.61), Basic Need Satisfaction Inventory (r = 0.61) and Cantril’s Ladder of Life Satisfaction (r = 0.63), and Katz Adjustment Scale for Relatives (socially expected activities, r = 0.51; free-time activities, r = −0.49, P < 0.01). The FPI-SF differentiated patients with an FEVl% predicted greater than and less than 50% (t = 4.26, P < 0.001), and those with severe and moderate levels of perceived severity and activity limitation (t = 9.91, P < 0.001). Conclusion: Results suggest the FPI-SF is a viable alternative to the FPI for situations in which a shorter instrument is desired. Further assessment of the instrument’s performance properties in new samples of patients with COPD is warranted. PMID:21191436

    Short form versions of the Parental-Caregivers Perception Questionnaire (P-CPQ) and Family Impact Scale (FIS) have been developed for use as measures of oral health-related quality of life in dental research. Objectives (1) To translate the original English short form versions of the P-CPQ and FIS and examine their validity, and (2) to describe the impact of early childhood caries on oral health-related quality of life in young Omani children and their families. Methods Parents/caregivers of children awaiting treatment for early childhood caries completed the P-CPQ and FIS at the Military Dental Center in Oman. Data were obtained from 191 families (representing a 94.1% participation rate). A global Oral Health Quality of Life (OHRQoL) item was used concurrently to examine the scales’ validity. Results The cross-sectional concurrent validity of the short form version of the P-CPQ was apparent in the significant gradient across the response categories of the global OHRQoL item, but the FIS short form version did not perform as well. Conclusion The P-CPQ appears to be valid, but further investigation of the FIS is required, along with examination of the scales’ responsiveness to change. PMID:26792967

    Clinician awareness of the importance of recognizing, assessing, and ultimately addressing the negative impact of chronic wounds on patient quality of life is increasing. One hundred, eighteen (118) patients (average age 78 years) participated in a study to evaluate the use of the Medical Outcomes Short Form-36 for assessing the health-related quality of life of patients with chronic leg ulceration. Most patients (104, 88%) were treated at home by community nurses. A medical history was obtained and patients completed the Short Form-36 questionnaire at baseline and after 12 weeks of receiving standard ulcer care. Published normative data were used to ascertain the effect of leg ulcers on health-related quality of life. Short Form-36 responsiveness was determined by comparing baseline and 12-week scores. Results suggest that the questionnaire is reliable for five of eight Short Form-36 domains (alpha > 0.8), with the remainder alpha > 0.7. Compared to age-sex adjusted published normative scores, patients with leg ulcers had significantly lower mean scores in the following domains: role-emotional (d = 28.6, P <0.001), social functioning (d = 22.8, P <0.001), role-functioning (d = 20.8, P <0.001), role-physical (d = 20.7, P <0.001), and bodily pain (d = 12.3, P <0.001). Short Form-36 scores barely changed between baseline and the 12-week assessment, but bodily pain improved in the 31 patients whose ulcers healed during that time (d = 14.6, P = 0.006; SRM = 0.60). Pain did not improve in patients whose ulcers remained open (d = -2.1, P = 0.45). Compared to patients whose ulcers did not heal, patients with healed ulcers experienced greater improvements in the following domains: body pain (d = 16.8, P = 0.003), mental health (d = 9.4, P = 0.013), role-physical (d = 19.7, P = 0.06), role-emotional (d = 17.2, P = 0.12), and vitality (d = 9.0, P = 0.052). The results of this study suggest that leg ulcers reduce patient quality of life and that the Short Form-36 can be used

    2014-12-01

    In educational settings, quick assessments of intelligence are often required to screen children with potential special needs. The WISC-IV is administered individually and takes between one and two hours to complete. Given its widespread use in Spain, a short-form of the Spanish version is likely to be of use to professionals. The goal of this research was to develop a short form of the WISC-IV that can be performed in approximately half an hour. Data obtained in 100 elementary school children were analyzed following the criteria of Resnick and Entin (1971) . The results showed that the most accurate estimation of intelligence was achieved with a combination of the Vocabulary, Block Design, Letter-Number Sequencing, and Coding subtests. PMID:25539178

    2016-10-01

    This study examines the psychometric properties of the self-report version of the Inventory of Callous-Unemotional Traits in 191 detained female adolescents (M = 15.76, SD = 1.02). Evidence supporting the validity of the ICU scores was generally weak, largely due to poor functioning of the Unemotional subscale. Results from confirmatory factor analyses demonstrated support for a recently proposed shortened version of the ICU consisting of two subscales (Callousness and Uncaring). Both subscales showed acceptable to good internal consistency. This short-form version also improved criterion validity, though some issues regarding its convergent validity need further consideration. In conclusion, this study suggests that a short-form version of the ICU that includes a subset of the original items may hold promise as an efficient and valid method for assessing CU traits.

    Few studies have assessed the psychometric properties of the Personality Assessment Inventory short-form (PAI-SF) clinical scales, and none have conducted these evaluations using participants from psychiatric inpatient units. The present study evaluated item-level tests of scaling assumptions of the PAI-SF using a large (N=503) clinical sample of participants who completed the PAI during their admission to a psychiatric inpatient unit. Internal consistency reliability was high across scales, and tests of item-scale convergence and discrimination generally confirmed hypothesized item groupings. Scale-level correlations supported unique variance being measured by each scale. Finally, agreement between the PAI short- and full-form scales was found to be high. The results are discussed with regards to scale interpretation. PMID:19879654

    OBJECTIVE To propose a short version of the Brazilian Food Insecurity Scale. METHODS Two samples were used to test the results obtained in the analyses in two distinct scenarios. One of the studies was composed of 230 low income families from Pelotas, RS, Southern Brazil, and the other was composed of 15,575 women, whose data were obtained from the 2006 National Survey on Demography and Health. Two models were tested, the first containing seven questions, and the second, the five questions that were considered the most relevant ones in the concordance analysis. The models were compared to the Brazilian Food Insecurity Scale, and the sensitivity, specificity and accuracy parameters were calculated, as well as the kappa agreement test. RESULTS Comparing the prevalence of food insecurity between the Brazilian Food Insecurity Scale and the two models, the differences were around 2 percentage points. In the sensitivity analysis, the short version of seven questions obtained 97.8% and 99.5% in the Pelotas sample and in the National Survey on Demography and Health sample, respectively, while specificity was 100% in both studies. The five-question model showed similar results (sensitivity of 95.7% and 99.5% in the Pelotas sample and in the National Survey on Demography and Health sample, respectively). In the Pelotas sample, the kappa test of the seven-question version totaled 97.0% and that of the five-question version, 95.0%. In the National Survey on Demography and Health sample, the two models presented a 99.0% kappa. CONCLUSIONS We suggest that the model with five questions should be used as the short version of the Brazilian Food Insecurity Scale, as its results were similar to the original scale with a lower number of questions. This version needs to be administered to other populations in Brazil in order to allow for the adequate assessment of the validity parameters. PMID:25372169

    The present work describes the process of developing an item bank and short forms that measure the impact of asthma on quality of life (QoL) that avoids confounding QoL with asthma symptomatology and functional impairment. Using a diverse national sample of adults with asthma (N = 2032) we conducted exploratory and confirmatory factor analyses, and item response theory and differential item functioning analyses to develop a 65-item unidimensional item bank and separate short form assessments. A psychometric evaluation of the RAND Impact of Asthma on QoL item bank (RAND-IAQL) suggests that though the concept of asthma impact on QoL is multi-faceted, it may be measured as a single underlying construct. The performance of the bank was then evaluated with a real-data simulated computer adaptive test. From the RAND-IAQL item bank we then developed two short forms consisting of 4 and 12 items (reliability = 0.86 and 0.93, respectively). A real-data simulated computer adaptive test suggests that as few as 4-5 items from the bank are needed to obtain highly precise scores. Preliminary validity results indicate that the RAND-IAQL measures distinguish between levels of asthma control. To measure the impact of asthma on QoL, users of these items may choose from two highly reliable short forms, computer adaptive test administration, or content-specific subsets of items from the bank tailored to their specific needs.

    G-quadruplexes (G4) are polymorphic four-stranded structures formed by certain G-rich nucleic acids, with various biological roles. However, structural features dictating their formation and/or functionin vivo are unknown. InS. cerevisiae, the pathological persistency of G4 within the CEB1 minisatellite induces its rearrangement during leading-strand replication. We now show that several other G4-forming sequences remain stable. Extensive mutagenesis of the CEB25 minisatellite motif reveals that only variants with very short (≤ 4 nt) G4 loops preferentially containing pyrimidine bases trigger genomic instability. Parallel biophysical analyses demonstrate that shortening loop length does not change the monomorphic G4 structure of CEB25 variants but drastically increases its thermal stability, in correlation with thein vivo instability. Finally, bioinformatics analyses reveal that the threat for genomic stability posed by G4 bearing short pyrimidine loops is conserved inC. elegans and humans. This work provides a framework explanation for the heterogeneous instability behavior of G4-forming sequencesin vivo, highlights the importance of structure thermal stability, and questions the prevailing assumption that G4 structures with short or longer loops are as likely to formin vivo.

    Objective To develop a self-reported measure of the subjective impact of pressure ulcers on health-related quality of life (HRQOL) in individuals with spinal cord injury (SCI) as part of the SCI quality of life (SCI-QOL) measurement system. Design Grounded-theory based qualitative item development methods, large-scale item calibration testing, confirmatory factor analysis (CFA), and item response theory-based psychometric analysis. Setting Five SCI Model System centers and one Department of Veterans Affairs medical center in the United States. Participants Adults with traumatic SCI. Main Outcome Measures SCI-QOL Pressure Ulcers scale. Results 189 individuals with traumatic SCI who experienced a pressure ulcer within the past 7 days completed 30 items related to pressure ulcers. CFA confirmed a unidimensional pool of items. IRT analyses were conducted. A constrained Graded Response Model with a constant slope parameter was used to estimate item thresholds for the 12 retained items. Conclusions The 12-item SCI-QOL Pressure Ulcers scale is unique in that it is specifically targeted to individuals with spinal cord injury and at every stage of development has included input from individuals with SCI. Furthermore, use of CFA and IRT methods provide flexibility and precision of measurement. The scale may be administered in its entirety or as a 7-item “short form” and is available for both research and clinical practice. PMID:26010965

    Background Substance use disorders (SUDs) are one of the nation’s most costly problems in terms of dollars, disability, and death. Self-help programs are among the varied recovery support options available to address SUD, and evaluation of these programs depends on good measurement. There exists an unmet need for a psychometrically sound, brief, efficient measure of self-help involvement for individuals with SUD that is valid across different substances and age-groups. Methods Using data from 2,101 persons presenting for SUD treatment, the full 21-item Global Appraisal of Individual Needs Self-Help Involvement Scale (SHIS) and a newly developed 11-item short-form version were validated against the Rasch measurement model and each other. Differential item functioning (DIF) was assessed by primary substance and age. Results Both versions met Rasch psychometric criteria. The full scale had minor misfit with no DIF for alcohol, marijuana, or opioids but a few instances of DIF for amphetamine and cocaine users as well as for age, in that youth tended to endorse several easier items more frequently than did adults. The 11-item short form had neither misfit nor DIF by substance and only minor DIF by age was highly correlated with the full version and was relatively more efficient. Criterion-related validity was supported for both. Conclusions Both the long and short versions of SHIS are psychometrically sound measures of a more comprehensive conceptualization of self-help involvement for SUDs that can be used as part of an in-depth assessment or as a short measure that lessens respondent burden.

    Patient experience reflects quality of care from the patients’ perspective; therefore, patients’ experiences are important data in the evaluation of the quality of health services. The development of an abbreviated, reliable and valid instrument for measuring inpatients’ experience would reflect the key aspect of inpatient care from patients’ perspective as well as facilitate quality improvement by cultivating patient engagement and allow the trends in patient satisfaction and experience to be measured regularly. The study developed a short-form inpatient instrument and tested its ability to capture a core set of inpatients’ experiences. The Hong Kong Inpatient Experience Questionnaire (HKIEQ) was established in 2010; it is an adaptation of the General Inpatient Questionnaire of the Care Quality Commission created by the Picker Institute in United Kingdom. This study used a consensus conference and a cross-sectional validation survey to create and validate a short-form of the Hong Kong Inpatient Experience Questionnaire (SF-HKIEQ). The short-form, the SF-HKIEQ, consisted of 18 items derived from the HKIEQ. The 18 items mainly covered relational aspects of care under four dimensions of the patient’s journey: hospital staff, patient care and treatment, information on leaving the hospital, and overall impression. The SF-HKIEQ had a high degree of face validity, construct validity and internal reliability. The validated SF-HKIEQ reflects the relevant core aspects of inpatients’ experience in a hospital setting. It provides a quick reference tool for quality improvement purposes and a platform that allows both healthcare staff and patients to monitor the quality of hospital care over time. PMID:25860775

    HD 140283 is an extremely metal-deficient and high-velocity subgiant in the solar neighborhood, having a location in the Hertzsprung-Russell diagram where absolute magnitude is most sensitive to stellar age. Because it is bright, nearby, unreddened, and has a well-determined chemical composition, this star avoids most of the issues involved in age determinations for globular clusters. Using the Fine Guidance Sensors on the Hubble Space Telescope, we have measured a trigonometric parallax of 17.15 {+-} 0.14 mas for HD 140283, with an error one-fifth of that determined by the Hipparcos mission. Employing modern theoretical isochrones, which include effects of helium diffusion, revised nuclear reaction rates, and enhanced oxygen abundance, we use the precise distance to infer an age of 14.46 {+-} 0.31 Gyr. The quoted error includes only the uncertainty in the parallax, and is for adopted surface oxygen and iron abundances of [O/H] = -1.67 and [Fe/H] = -2.40. Uncertainties in the stellar parameters and chemical composition, especially the oxygen content, now contribute more to the error budget for the age of HD 140283 than does its distance, increasing the total uncertainty to about {+-}0.8 Gyr. Within the errors, the age of HD 140283 does not conflict with the age of the Universe, 13.77 {+-} 0.06 Gyr, based on the microwave background and Hubble constant, but it must have formed soon after the big bang.

  19. Proteus virulence: involvement of the pore forming alpha-hemolysin (a short review).

    2000-01-01

    The genus Proteus belongs to the tribe of Proteae in the family of Enterobacteriaceae, and consists of five species: P. mirabilis, P. vulgaris, P. morganii, P. penneri and P. myxofaciens. They are distinguished from the rest of Enterobacteriaceae by their ability to deaminate phenylalanine and tryptophane. They hydrolyze urea and gelatin and fail to ferment lactose, mannose, dulcitol and malonate; and do not form lysine and arginine decarboxylase or beta-galactosidase [1]. Colonies produce distinct "burned chocolate" odor and frequently show the characteristics of swarming motility on solid media. P. mirabilis, P. vulgaris and P. morganii are widely recognized human pathogens. They have been isolated from urinary tract infections, wounds, ear, and nosocomial bacteremic infections, often in immuncompromised patients [2-6]. P. myxofaciens has no clinical interest to this time. P. penneri as species nova was nominated by the recommendation of Hickman and co-workers [7]. Formerly it was recognized as P. vulgaris biogroup 1 or indole negative P. vulgaris [8, 9]. Although it has been less commonly isolated from clinical samples than the other three human pathogenic Proteus species, it has nevertheless been connected with infections of the urinary tract, wounds and has been isolated from the feces of both healthy and diarrheic individuals [10-12]. Potential virulence factors responsible for virulence of Proteae are: IgA protease, urease, type3 fimbriae associated with MR/K haemagglutinins of at least two antigenic types, endotoxin, swarming motility and HlyA and/or HpmA type hemolysins [for review see ref. 13]. In the followings we give a survey of accumulated concepts about the position and characteristics of HlyA type alpha-hemolysins both in general and with emphasis on virulence functions in the tribe of Proteae.

    Purpose The purpose of this study was to calibrate the items for the Communicative Participation Item Bank (CPIB) using Item Response Theory (IRT). One overriding objective was to examine if the IRT item parameters would be consistent across different diagnostic groups, thereby allowing creation of a disorder-generic instrument. The intended outcomes were the final item bank and a short form ready for clinical and research applications. Methods Self-report data were collected from 701 individuals representing four diagnoses: multiple sclerosis, Parkinson’s disease, amyotrophic lateral sclerosis and head and neck cancer. Participants completed the CPIB and additional self-report questionnaires. CPIB data were analyzed using the IRT Graded Response Model (GRM). Results The initial set of 94 candidate CPIB items were reduced to an item bank of 46 items demonstrating unidimensionality, local independence, good item fit, and good measurement precision. Differential item function (DIF) analyses detected no meaningful differences across diagnostic groups. A 10-item, disorder-generic short form was generated. Conclusions The CPIB provides speech-language pathologists with a unidimensional, self-report outcomes measurement instrument dedicated to the construct of communicative participation. This instrument may be useful to clinicians and researchers wanting to implement measures of communicative participation in their work. PMID:23816661

    The aim of the present study was to develop and validate a short form of the Genderism and Transphobia Scale and assess adolescents' attitudes toward transpeople. A total of 800 Spanish adolescents aged between 14 and 18 years (50.70% girls, 49.30% boys) completed the Spanish version of the scale and other related questionnaires. The short form of the scale is composed of 12 items clustered into two factors (Transphobia/Genderism and Gender Bashing) that explain 54.22% of the variance. All the items showed good discriminating power, and the present scale demonstrated adequate reliability and validity. In the study, boys exhibited significantly more negative attitudes toward transpeople than girls did, both in the affective/cognitive dimension (Transphobia/Genderism) and in the behavioral dimension (Gender Bashing). Moreover, adolescents showed significantly more negative attitudes toward gender-nonconforming men than toward gender-nonconforming women. These results are discussed in terms of their relevance to the maintenance of discriminatory attitudes toward sexual diversity. PMID:23767992

    Studies investigating self-esteem in individuals with severe mental illness, either as a treatment goal, outcome or correlate to other variables, have increased over the past few years. One of the main difficulties in assessing self-esteem is the assessment itself, often measuring global and stable self-esteem as in the Rosenberg Self-Esteem Scale, or requiring extensive training and long interviews. The present article aims at demonstrating the relevance of the French and English versions of the Self-Esteem Rating Scale-Short Form with individuals with severe mental illness. The instrument's reliability and validity were investigated in a sample of 250 French Canadian college students, 247 British college students and three samples of English- or French-speaking individuals with severe mental illness (N=254, N=150 and N=171). Confirmatory factor analysis revealed that a shorter version of the instrument (20 items), with a positive and a negative self-esteem factor, had a great validity for all the samples studied. The Self-Esteem Rating Scale-Short Form, with its positive and negative self-esteem subscales, appears to be a valid and reliable self-esteem measure for individuals with mental health problems. Limitations of this study and future directions are discussed. PMID:16725210

    We present results of ab initio molecular dynamics study of the structural transformation occurring in hot liquid sulfur under high pressure, which corresponds to the recently observed chain-breakage phenomenon and to the electronic transition reported earlier. The transformation is temperature-induced and separates two distinct polymeric forms of liquid sulfur: high-temperature form composed of short chain-like fragments with open endings and low-temperature form with very long chains. We offer a structural description of the two liquid forms in terms of chain lengths, cross-linking, and chain geometry and investigate several physical properties. We conclude that the transformation is accompanied by changes in energy (but not density) as well as in diffusion coefficient and electronic properties—semiconductor-metal transition. We also describe the analogy of the investigated process to similar phenomena that take place in two other chalcogens selenium and tellurium. Finally, we remark that the behavior of heated liquid sulfur at ambient pressure might indicate a possible existence of a critical point in the low-pressure region of sulfur phase diagram.

    The reliability and validity of three short forms of the Dutch version of the Wechsler Memory Scale-Fourth Edition (WMS-IV-NL) were evaluated in a mixed clinical sample of 235 patients. The short forms were based on the WMS-IV Flexible Approach, that is, a 3-subtest combination (Older Adult Battery for Adults) and two 2-subtest combinations (Logical Memory and Visual Reproduction and Logical Memory and Designs), which can be used to estimate the Immediate, Delayed, Auditory and Visual Memory Indices. All short forms showed good reliability coefficients. As expected, for adults (16-69 years old) the 3-subtest short form was consistently more accurate (predictive accuracy ranged from 73% to 100%) than both 2-subtest short forms (range = 61%-80%). Furthermore, for older adults (65-90 years old), the predictive accuracy of the 2-subtest short form ranged from 75% to 100%. These results suggest that caution is warranted when using the WMS-IV-NL Flexible Approach short forms to estimate all four indices. PMID:26160974

    The aim of this study was to develop and validate a short form of the Brazilian version of McGill Pain Questionnaire (SF-MPQ). Three hundred two patients with chronic pain filled out the validated Brazilian long form of the McGill Pain Questionnaire (LF-MPQ). Words chosen by ≥25% of the patients were selected to comprise the SF-MPQ. The Brazilian SF-MPQ consisted of 15 descriptors (8 sensory, 5 affective, and 2 evaluative) rated on a binary mode (present or absent). Four pain scores were derived by counting the words chosen by the patients for sensory, affective, evaluative, and total descriptors. The SF-MPQ showed poor internal consistency (KR-20 = 0.52) but possibly acceptable because it showed discriminant validity to discriminate patients presenting different levels and mechanisms of pain, and it was strongly correlated with the LF-MPQ. The low KR-20 coefficient could result from the small number of items. The Brazilian version of the SF-MPQ proved to be a useful instrument to evaluate the different qualities of pain. It is a reliable option to the long-form MPQ. PMID:24315244

  7. The short form of the CheA protein restores kinase activity and chemotactic ability to kinase-deficient mutants.

    Escherichia coli expresses two forms of the chemotaxis-associated CheA protein, CheAL and CheAS, as the result of translational initiation at two distinct, in-frame initiation sites in the gene cheA. The long form, CheAL, plays a crucial role in the chemotactic signal transduction mechanism by phosphorylating two other chemotaxis proteins: CheY and CheB. CheAL must first autophosphorylate at amino acid His-48 before transferring its phosphono group to these other signal transduction proteins. The short form, CheAS, lacks the N-terminal 97 amino acids of CheAL and, therefore, does not possess the site of autophosphorylation. Here we demonstrate that although it lacks the ability to autophosphorylate, CheAS can mediate phosphorylation of kinase-deficient variants of CheAL each of which retains a functional autophosphorylation site. This transphosphorylation enables these kinase-deficient CheAL variants to phosphorylate CheY. Because it mediates this activity, CheAS can restore to kinase-deficient E. coli cells the ability to tumble and, thus, to perform chemotaxis in swarm plate assays. Images PMID:8434013

    Trait emotional intelligence refers to a constellation of emotional self-perceptions located at the lower levels of personality hierarchies. In 2 studies, we sought to examine the psychometric properties of the Trait Emotional Intelligence Questionnaire-Short Form (TEIQue-SF; Petrides, 2009) using item response theory (IRT). Study 1 (N= 1,119, 455 men) showed that most items had good discrimination and threshold parameters and high item information values. At the global level, the TEIQue-SF showed very good precision across most of the latent trait range. Study 2 (N= 866, 432 men) used similar IRT techniques in a new sample based on the latest version of the TEIQue-SF (version 1.50). Results replicated Study 1, with the instrument showing good psychometric properties at the item and global level. Overall, the 2 studies suggest the TEIQue-SF can be recommended when a rapid assessment of trait emotional intelligence is required. PMID:20706931

    This study evaluated the Brief Pain Inventory-Short Form (BPI-SF) in patients with moderate-to-severe systemic lupus erythematosus (SLE). Patients ≥18 years old who self-reported a physician diagnosis of SLE (confirmed by medical record review) and active SLE (Systemic Lupus Activity Questionnaire (SLAQ) score of ≥11) were included. The BPI-SF and Short Form Health Survey version 2 (SF-36v2) were administered electronically at baseline, week 2 and week 12. Psychometric properties of the BPI-SF were evaluated. Cronbach alphas were >0.9 for all BPI-SF items, domains and total score. Test-retest reliability correlations for responses between baseline and week 2 of the BPI-SF had intraclass correlation coefficients (ICCs) ≥0.5. The BPI-SF domains and total score were moderately positively correlated to the SLAQ score (r ≥ 0.4), but negatively correlated to the SF-36v2 bodily pain domain (r ≤ -0.6). The BPI-SF domains and total score were moderately negatively correlated to the SF-36v2 physical functioning domain and physical component summary (r ≤ -0.4), with low correlations between the BPI-SF severity domain and SF-36v2 mental component summary (r = -0.16). Assessment of pain, as measured by the BPI-SF, demonstrated validity and reliability in a sample of patients with moderate-to-severe SLE. PMID:26038345

    Children's personality traits are invaluable predictors of concurrent and later mental and physical health. Several validated longer inventories for assessing the widely recognized Five-Factor Model of personality in children are available, but short forms are scarce. This study aimed at constructing a 30-item form of the 144-item Hierarchical Personality Inventory for Children (HiPIC) (Mervielde & De Fruyt, ). Participants were 1543 children aged 6-12 years (sample 1) and 3895 children aged 8 years (sample 2). Sample 1 completed the full HiPIC, from which we constructed the HiPIC-30, and the Child Behaviour Checklist (Achenbach, ). Sample 2 completed the HiPIC-30. The HiPIC-30 personality domains correlated over r = .90 with the full HiPIC domains, had good Cronbach's alphas and correlated similarly with CBCL behaviour problems and gender as the full HiPIC. The factor structures of the HiPIC-30 were convergent across samples, but the imagination factor was not clear-cut. We conclude that the HiPIC-30 is a reliable and valid questionnaire for the Five-Factor personality traits in children. Copyright © 2016 John Wiley & Sons, Ltd. PMID:27120426

    The goal of this investigation was the development of an inconsistency scale (ICN-SF) for the personality assessment inventory-short form (PAI-SF). In Study 1, 503 inpatient profiles were randomly assigned to a derivation or cross-validation sample. Ten correlated item pairs were identified using the derivation sample and placed on the ICN-SF. Psychometric properties of the ICN-SF total scores were comparable in the derivation and cross-validation samples. Total ICN-SF scores in both samples were significantly lower than scores obtained from computer-generated random samples. Diagnostic efficiency statistics are reported using multiple cut-off scores at various base rate estimates. ICN-SF scores greater than 8 reasonably balanced sensitivity and specificity rates. This cutoff correctly classified 92% of the random protocols and inaccurately classified 9% of the patient protocols in study 1. In study 2, PAI-SF scores from 627 forensic and civil inpatients produced similar results, effectively identifying cases with elevated scores on the full-form inconsistency scale. Overall the results of both studies suggest that the ICN-SF can aid examiners in assessing for inconsistent responding. PMID:22574923

    Objectives We aimed to develop and validate Kinyarwanda versions of Short-Form Leeds Dyspepsia Questionnaire (SF-LDQ) and Short-Form Nepean Dyspepsia Index (SF-NDI) to measure the frequency and severity of dyspepsia and associated quality-of-life impact in Rwanda. Setting A single, tertiary care centre in Rwanda. Participants 200 consecutive Kinyarwanda-speaking patients referred to endoscopy (100 patients) or medical outpatients (100 patients). Interventions Kinyarwanda versions of the SF-LDQ and SF-NDI were developed from English versions by translation, with back translation, crosschecking and pilot testing. Study participants completed these questionnaires at enrolment (time 1), and then completed the surveys again with blinded phone interviewers 3 days later (time 2). 20 randomly selected participants, diagnosed with a peptic ulcer on index endoscopy, completed a third survey by phone at day 30 (time 3), after therapy. Primary outcome measures Internal consistency at time 1 (by Cronbach's α) and test–retest reliability between time 1 and time 2 (Spearman's correlation coefficient) for translated SF-LDQ and SF-NDI; validity versus clinical diagnosis (by receiver operating characteristic (ROC) curve) and responsiveness to treatment for SF-LDQ (by change in mean score). All outcomes were measured as per protocol. Results Cronbach's α of the translated SF-LDQ was 0.93, showing high internal consistency. Spearman's correlation coefficient comparing time 1 and time 2 was 0.978 (p<0.001), demonstrating high reliability. Cronbach's α for the translated SF-NDI was 0.92. A cut-off score of 16 on the SF-LDQ showed a sensitivity of 97% and a specificity of 71% for the diagnosis of dyspepsia, correctly classifying 89% of patients. In the responsiveness analysis, the mean SF-LDQ score was reduced from 20.1 prior to treatment to 13.9 after 30 days of treatment (p=0.003). Conclusions The Kinyarwanda versions of the SF-LDQ and SF-NDI were valid, reliable and

    We present the discovery and characterization of PTF10iya, a short-lived (Δt≈ 10 d, with an optical decay rate of ˜0.3 mag d-1), luminous (? mag) transient source found by the Palomar Transient Factory. The ultraviolet/optical spectral energy distribution is reasonably well fitted by a blackbody with T≈ (1-2) × 104 K and peak bolometric luminosity LBB≈ (1-5) × 1044 erg s-1 (depending on the details of the extinction correction). A comparable amount of energy is radiated in the X-ray band that appears to result from a distinct physical process. The location of PTF10iya is consistent with the nucleus of a star-forming galaxy (z= 0.224 05 ± 0.000 06) to within 350 mas (99.7 per cent confidence radius), or a projected distance of less than 1.2 kpc. At first glance, these properties appear reminiscent of the characteristic 'big blue bump' seen in the near-ultraviolet spectra of many active galactic nuclei (AGNs). However, emission-line diagnostics of the host galaxy, along with a historical light curve extending back to 2007, show no evidence for AGN-like activity. We therefore consider whether the tidal disruption of a star by an otherwise quiescent supermassive black hole may account for our observations. Though with limited temporal information, PTF10iya appears broadly consistent with the predictions for the early 'super-Eddington' phase of a solar-type star being disrupted by a ˜107 M⊙ black hole. Regardless of the precise physical origin of the accreting material, the large luminosity and short duration suggest that otherwise quiescent galaxies can transition extremely rapidly to radiate near the Eddington limit; many such outbursts may have been missed by previous surveys lacking sufficient cadence.

    A continuous assessment and a categorical diagnosis of the presence of mental health, described as flourishing, and the absence of mental health, characterized as languishing, is applied to a random sample of 1050 Setswana-speaking adults in the Northwest province of South Africa. Factor analysis revealed that the mental health continuum-short form (MHC-SF) replicated the three-factor structure of emotional, psychological and social well-being found in US samples. The internal reliability of the overall MHC-SF Scale was 0.74. The total score on the MHC-SF correlated 0.52 with a measure of positive affect, between 0.35 and 0.40 with measures of generalized self-efficacy and satisfaction with life, and between 0.30 and 0.35 with measures of coping strategies, sense of coherence, and community collective self-efficacy. The total score on the MHC-SF correlated -0.22 with the total score on the General Health Questionnaire. Criteria for the categorical diagnosis were applied, and findings revealed that 20% were flourishing, 67.8% were moderately mentally healthy, and 12.2% were languishing. Confirmatory factor analysis supported the hypothesized two-continua model of mental health and mental illness found in the USA. PMID:19115439

    The primary objective of this study was to translate and validate Situational Inventory of Body-Image Dysphoria-Short form (SIBID-S) in a Spanish population. The scale consists of 20 items to assess the frequency of dysphoric body-image emotions in certain situational contexts, using a five-point rating scale. The questionnaire was administered to 214 women between the ages of 14 and 29 years, from primary and secondary schools and a university. Principal components analysis indicated a one-factor structure for the entire sample and both younger (<18) and older (>or=18) participants. Internal consistency was high (0.94), and the test-retest reliability over 1 month ranged between 0.89 and 0.93. The SIBID-S showed good convergent validity in relation to other pertinent measures of body image, eating pathology, and self-esteem. Moreover, the SIBID-S was differentiated low-risk, subclinical eating disturbed, and clinical eating disordered patients. Results support the potential utility of the SIBID-S in the Spanish female population, including a younger group than previously studied, as well as its usefulness in the assessment of body image among females varying in degrees of eating pathology.

    Relying upon our previous treatment of the density matrices for nuclei (in general, nonrelativistic self-bound finite systems) we are studying a combined effect of center-of-mass motion and short-range nucleon-nucleon correlations on the nucleon density and momentum distributions in light nuclei (4He and 16O). Their intrinsic ground-state wave functions are constructed in the so-called fixed center-of-mass approximation, starting with mean-field Slater determinants modified by some correlator ( e.g., after Jastrow or Villars). We develop the formalism based upon the Cartesian or boson representation, in which the coordinate and momentum operators are linear combinations of the creation and annihilation operators for oscillatory quanta in the three different space directions, and get the own "Tassie-Barker" factors for each distribution and point out other model-independent results. After this separation of the center-of-mass motion effects we propose additional analytic means in order to simplify the subsequent calculations ( e.g., within the Jastrow approach or the unitary correlation operator method). The charge form factors, densities and momentum distributions of 4He and 16O evaluated by using the well-known cluster expansions are compared with data, our exact (numerical) results and microscopic calculations.

    Mindfulness-based interventions are increasingly being used in various populations to improve well-being and reduce psychological afflictions. However, there is lack of a validated mindfulness measurement in the Chinese language. This study validated the Chinese version of the Five Facet Mindfulness Questionnaire (FFMQ-C) in both a community sample of 230 adults and a clinical sample of 156 patients with significant psychological distress. Results showed a good test-retest reliability (.88) and a high internal consistency (.83 in the community sample and .80 in the clinical sample). Mindfulness as measured by FFMQ-C has moderate to large correlations with psychological distress and mental well-being. Two of the five subscales (describing and acting with awareness) showed incremental validity over the others in predicting psychological symptoms and mental health. Confirmatory factor analysis confirmed the five-factor structure of the FFMQ-C and demonstrated adequate model fit. A 20-item short form scale (FFMQ-SF) was developed using the proposed comprehensive criteria. These findings indicate that the FFMQ-C is reliable and valid to measure mindfulness in a Chinese population. Further study is needed to evaluate the psychometric properties of FFMQ-SF.

    Financial capacity is an instrumental activity of daily living (IADL) that comprises multiple abilities and is critical to independence and autonomy in older adults. Because of its cognitive complexity, financial capacity is often the first IADL to show decline in prodromal and clinical Alzheimer's disease and related disorders. Despite its importance, few standardized assessment measures of financial capacity exist and there is little, if any, normative data available to evaluate financial skills in the elderly. The Financial Capacity Instrument-Short Form (FCI-SF) is a brief measure of financial skills designed to evaluate financial skills in older adults with cognitive impairment. In the current study, we present age- and education-adjusted normative data for FCI-SF variables in a sample of 1344 cognitively normal, community-dwelling older adults participating in the Mayo Clinic Study of Aging (MCSA) in Olmsted County, Minnesota. Individual FCI-SF raw scores were first converted to age-corrected scaled scores based on position within a cumulative frequency distribution and then grouped within 4 empirically supported and overlapping age ranges. These age-corrected scaled scores were then converted to age- and education-corrected scaled scores using the same methodology. This study has the potential to substantially enhance financial capacity evaluations of older adults through the introduction of age- and education-corrected normative data for the FCI-SF by allowing clinicians to: (a) compare an individual's performance to that of a sample of similar age and education peers, (b) interpret various aspects of financial capacity relative to a normative sample, and (c) make comparisons between these aspects.

  20. Development of a Short-Form Measure of Science and Technology Self-efficacy Using Rasch Analysis

    Despite an increased focus on science, technology, engineering, and mathematics (STEM) in U.S. schools, today's students often struggle to maintain adequate performance in these fields compared with students in other countries (Cheek in Thinking constructively about science, technology, and society education. State University of New York, Albany, 1992; Enyedy and Goldberg 2004; Mandinach and Lewis 2006). In addition, despite considerable pressure to promote the placement of students into STEM career fields, U.S. placement is relatively low (Sadler et al. in Sci Educ 96(3):411-427, 2012; Subotnik et al. in Identifying and developing talent in science, technology, engineering, and mathematics (STEM): an agenda for research, policy and practice. International handbook, part XII, pp 1313-1326, 2009). One explanation for the decline of STEM career placement in the U.S. rests with low student affect concerning STEM concepts and related content, especially in terms of self-efficacy. Researchers define self-efficacy as the internal belief that a student can succeed in learning, and that understanding student success lies in students' externalized actions or behaviors (Bandura in Psychol Rev 84(2):191-215, 1977). Evidence suggests that high self-efficacy in STEM can result in student selection of STEM in later educational endeavors, culminating in STEM career selection (Zeldin et al. in J Res Sci Teach 45(9):1036-1058, 2007). However, other factors such as proficiency play a role as well. The lack of appropriate measures of self-efficacy can greatly affect STEM career selection due to inadequate targeting of this affective trait and loss of opportunity for early intervention by educators. Lack of early intervention decreases selection of STEM courses and careers (Valla and Williams in J Women Minor Sci Eng 18(1), 2012; Lent et al. in J Couns Psychol 38(4), 1991). Therefore, this study developed a short-form measure of self-efficacy to help identify students in need of

    The Lesbian, Gay, and Bisexual Affirmative Counseling Self-Efficacy Inventory – Short Form (LGB-CSI-SF) was developed to facilitate LGB-affirmative counseling training, as well as process and outcome research, by offering a brief psychometrically supported version of the original LGB-CSI measure to researchers and clinicians. Five hundred seventy-five participants (435 licensed mental health professionals and 140 graduate students/trainees) constituted the sample. Confirmatory factor analyses of the 32 items from the original LGB-CSI yielded a new 15-item version of the measure composed of 5 factors (consisting of 3 items each) that assess counselor self-efficacy to perform lesbian, gay, and bisexual (LGB) affirmative counseling behaviors (Application of Knowledge, Advocacy Skills, Self-Awareness, Relationship, and Assessment). The LGB-CSI-SF evidenced high internal consistency and adequate test–retest stability. Convergent validity was supported by correlations between LGB-CSI-SF total scores and Application of Knowledge, Advocacy Skills, Relationship, and Assessment subscales and instruction in LGB issues, as well as personal/professional relations with LGB individuals. More affirmative attitudes toward LGB persons positively related with total scores and Advocacy Skills, Self-Awareness, and Relationship subscales. Discriminant validity was evidenced by an absence of relations between LGB-CSI-SF subscales and a measure of impression management. We found no associations between Advocacy Skills, Assessment, and Relationship subscales and a measure of Self-Deception. Recommendations for implementing the LGB-CSI-SF in future LGB-affirmative counseling self-efficacy based research and training interventions are discussed. PMID:25992391

    OBJECTIVES: Cataract is a prevalent disease in the elderly, and negatively influences patients’ quality of life. This study was conducted to study the application of the World Health Organization Quality of Life Instrument, Short Form (WHOQOL-BREF) to patients with cataract. METHODS: In this cross-sectional study, 300 patients with cataract were studied in Neyshabur, Iran from July to October 2014. The Iranian version of the WHOQOL-BREF questionnaire was used to measure their quality of life. Cronbach’s alpha coefficient, Pearson’s correlation coefficient, the paired t-test, the independent t-test, and a linear regression model were used to analyze the data in SPSS version 16.0 (SPSS Inc., Chicago, IL, USA). RESULTS: The mean age of the participants was 68.11±11.98 years, and most were female (53%). The overall observed Cronbach’s alpha coefficient for the WHOQOL-BREF was 0.889, ranging from 0.714 to 0.810 in its four domains. The total mean score of the respondents on the WHOQOL-BREF was 13.19. The highest and lowest mean scores were observed in the social relationship domain (14.11) and the physical health domain (12.29), respectively. A backward multiple linear regression model found that duration of disease and marital status were associated with total WHOQOL scores, while age, duration of disease, marital status, and income level were associated with domains one through four, respectively (p<0.05). CONCLUSIONS: The reliability analysis conducted in this study indicated that the WHOQOL-BREF scale exhibited an acceptable degree of internal consistency in the measurement of the quality of life of patients with cataract. It was also found that the patients with cataract who were surveyed reported a relatively moderate quality of life. PMID:26883738

    Background The Boston Naming Test (BNT) is a commonly used neuropsychological test of confrontation naming that aids in determining the presence and severity of dysnomia. Many short versions of the original 60-item test have been developed and are routinely administered in clinical/research settings. Because of the common need to translate similar measures within and across studies, it is important to evaluate the operating characteristics and agreement of different BNT versions. Methods We analyzed longitudinal data of research volunteers (n = 681) from the University of Kentucky Alzheimer’s Disease Center longitudinal cohort. Conclusions With the notable exception of the Consortium to Establish a Registry for Alzheimer’s Disease (CERAD) 15-item BNT, short forms were internally consistent and highly correlated with the full version; these measures varied by diagnosis and generally improved from normal to mild cognitive impairment (MCI) to dementia. All short forms retained the ability to discriminate between normal subjects and those with dementia. The ability to discriminate between normal and MCI subjects was less strong for the short forms than the full BNT, but they exhibited similar patterns. These results have important implications for researchers designing longitudinal studies, who must consider that the statistical properties of even closely related test forms may be quite different.

    2013-01-01

    Background The Lililwan Project is the first population-based study to determine Fetal Alcohol Spectrum Disorders (FASD) prevalence in Australia and was conducted in the remote Fitzroy Valley in North Western Australia. The diagnostic process for FASD requires accurate assessment of gross and fine motor functioning using standardised cut-offs for impairment. The Bruininks-Oseretsky Test of Motor Proficiency, Second Edition (BOT-2) is a norm-referenced assessment of motor function used worldwide and in FASD clinics in North America. It is available in a Complete Form with 53 items or a Short Form with 14 items. Its reliability in measuring motor performance in children exposed to alcohol in utero or living in remote Australian Aboriginal communities is unknown. Methods A prospective inter-rater and test-retest reliability study was conducted using the BOT-2 Short Form. A convenience sample of children (n = 30) aged 7 to 9 years participating in the Lililwan Project cohort (n = 108) study, completed the reliability study. Over 50% of mothers of Lililwan Project children drank alcohol during pregnancy. Two raters simultaneously scoring each child determined inter-rater reliability. Test-retest reliability was determined by assessing each child on a second occasion using predominantly the same rater. Reliability was analysed by calculating Intra-Class correlation Coefficients, ICC(2,1), Percentage Exact Agreement (PEA) and Percentage Close Agreement (PCA) and measures of Minimal Detectable Change (MDC) were calculated. Results Thirty Aboriginal children (18 male, 12 female: mean age 8.8 years) were assessed at eight remote Fitzroy Valley communities. The inter-rater reliability for the BOT-2 Short Form score sheet outcomes ranged from 0.88 (95%CI, 0.77 – 0.94) to 0.92 (95%CI, 0.84 – 0.96) indicating excellent reliability. The test-retest reliability (median interval between tests being 45.5 days) for the BOT-2 Short Form score sheet outcomes ranged from

    Multicellular organisms are constantly exposed to a multitude of pathogenic microbes. Infection is inhibited in vivo by the innate and adaptive immune system. Mycobacterium species have emerged that are resistant to most antibiotics. We identified several naturally occurring cationic antimicrobial peptides that were active at low micromolar concentrations against Mycobacterium smegmatis. Human-derived cathelicidin LL-37 is well characterized and studied against M. smegmatis; we compared LL-37 with Chinese cobra-derived cathelicidin NA-CATH and mouse cathelicidin (mCRAMP). Two synthetic 11-residue peptides (ATRA-1A and ATRA-2) containing variations of a repeated motif within NA-CATH were tested for their activity against M. smegmatis along with a short synthetic peptide derivative from the human beta-defensin hBD3 (hBD3-Pep4). We hypothesized that these smaller synthetic peptides may demonstrate antimicrobial effectiveness with shorter length (and at less cost), making them strong potential candidates for development into broad-spectrum antimicrobial compounds or use in combination with antibiotics. These peptides have antimicrobial activity with EC50 ranging from 0.05 to 1.88 μg/mL against Mycobacterium smegmatis. The ATRA-1A short peptide was found to be the most effective antimicrobial peptide (AMP) (EC50 = 0.05 μg/mL). High bactericidal activity correlated with bacterial membrane depolarization and permeabilization activities. The efficacy of the peptides was further analyzed through Minimal Inhibitory Concentration (MIC) assays. The MICs were determined by the microdilution method. The peptide mCRAMP showed the best MIC activity at 15.6 μg/mL. Neither of the effective short synthetic peptides demonstrated synergy with the antibiotic rifampicin, although both demonstrated synergy with the cyclic peptide antibiotic polymyxin B. The peptides LL-37 and mCRAMP displayed synergism with rifampicin in MIC assays, whereas antibiotic polymyxin B displayed synergism

    Two consecutive rumen batch cultures were used to study the effect of nanoemulsified oils as a new type of supplement, on the in vitro fatty acid proportion and vaccenic acid formation. Three levels (3, 5, and 7%) of 2 different oil blends [soybean:fish oil (SF) or rapeseed-fish oil (RF)] were used. Both oil blends were used either in the raw form (SF or RF, respectively) or in the nanoemulsified form (NSF or NRF, respectively). The diets were the control (0%), which consisted of a dry total mixed ration without any supplements, the control plus 3, 5, or 7% of the SF or RF oil blend in appropriate form (raw or nanoemulsified). For each treatment, 6 incubation vessels were used. Each batch culture was incubated for 24h and conducted twice in 2 consecutive days. All supplements were calculated as a percentage of the substrate dry matter (400mg). Nanoemulsified supplements were recalculated to make sure the oil amount was equal to the raw oil supplementation levels. The results from both experiments indicated that the proportions of vaccenic acid and cis-9,trans-11 C18:2 increased when a raw oil blend was supplemented; on the other hand, no influence of nanoemulsified form of oil blend was observed on the proportion cis-9,trans-11 C18:2. Generally, supplementation with the nanoemulsified oil blends had less effect on biohydrogenation intermediates than the raw form of oil blends. However, the nanoemulsified form had a greater effect on the increase of n-3 and n-6 fatty acids. Nanoemulsified oil blends had a positive effect on decreasing the transformation rate of polyunsaturated fatty acids to saturated fatty acids in the biohydrogenation environment. Supplements of nanoemulsified oil blends tended to be more effective than supplements of raw oils in preserving a greater proportion of polyunsaturated fatty acids in the fermentation culture.

    Objective The aim of this study was to develop and validate a short form of the Eating Disorder Examination Questionnaire (EDE-Q) for routine, including session by session, outcome assessment. Method The current, 28-item version (6.0) of the EDE-Q was completed by 489 individuals aged 18–72 with various eating disorders recruited from three UK specialist eating disorder services. Rasch analysis was carried out on factors identified by means of principal component analysis, which in combination with expert ratings informed the development of an EDE-Q short form. The shortened questionnaire’s reliability, validity and sensitivity was assessed based on online data collected from students of a UK university and volunteers with a history of eating disorders recruited from a national eating disorders charity aged 18–74 (N = 559). Results A 12-item short form, the Eating Disorder Examination Questionnaire Short (EDE-QS) was derived. The new measure showed high internal consistency (Cronbach’s α = .913) and temporal stability (ICC = .93; p < .001). It was highly correlated with the original EDE-Q (r = .91 for people without ED; r = .82 for people with ED) and other measures of eating disorder and comorbid psychopathology. It was sufficiently sensitive to distinguish between people with and without eating disorders. Discussion The EDE-QS is a brief, reliable and valid measure of eating disorder symptom severity that performs similarly to the EDE-Q and that lends itself for the use of sessional outcome monitoring in treatment and research.

    Photonic crystals can be represented by periodic nanostructures with alternating refractive indices, which create artificial stop bands with the appearance of colors. In this regard, nanodomains of block copolymers and the corresponding structural colors have been intensively studied in the past. However, the practical application of photonic crystals of block copolymers has been limited to a large degree because of the presence of large defects and grain boundaries in the nanodomains of block copolymers. The present study focuses on the alternative opportunity of short-range ordered nanodomains of block copolymers for fluorescence enhancement, which also has a direct relevance to the development of fluorescence sensors or detectors. The enhancement mechanism was found to be interconnected with the excitation process rather than the alternation of the decay kinetics. In particular, we demonstrate that randomly oriented, but regular grains of lamellae of polystyrene-block-polyisoprene, PS-b-PI, diblock copolymers and their blend with PS homopolymers can behave as Bragg mirrors to induce multiple reflections of the excitation source inside the photonic structures. This process in turn significantly increases the effective absorption of the given fluorophores inside the polymeric photonic structures to amplify the fluorescence signal.Photonic crystals can be represented by periodic nanostructures with alternating refractive indices, which create artificial stop bands with the appearance of colors.

    In psychological research, there is a growing interest in using latent class analysis (LCA) for the investigation of quantitative constructs. The aim of this study is to illustrate how LCA can be applied to gain insights on a construct and to select items during test development. We show the added benefits of LCA beyond factor-analytic methods, namely being able (1) to describe groups of participants that differ in their response patterns, (2) to determine appropriate cutoff values, (3) to evaluate items, and (4) to evaluate the relative importance of correlated factors. As an example, we investigated the construct of Facebook addiction using the Facebook Addiction Test (F-AT), an adapted version of the Internet Addiction Test (I-AT). Applying LCA facilitates the development of new tests and short forms of established tests. We present a short form of the F-AT based on the LCA results and validate the LCA approach and the short F-AT with several external criteria, such as chatting, reading newsfeeds, and posting status updates. Finally, we discuss the benefits of LCA for evaluating quantitative constructs in psychological research. PMID:26931108

    This study demonstrates that Amblyomma americanum (Aam) constitutively and ubiquitously expresses the long (L) and short (S) putative acidic chitinases (Ach) that are distinguished by a 210 base pair (bp) deletion in AamAch-S. Full-length AamAch-L and AamAch-S cDNA are 1959 and 1718 bp long, containing 1332 and 1104 bp open reading frames that code for 443 and 367 amino acid residues proteins with the former predicted to be extracellular and the latter intracellular. Both AamAch-L and AamAch-S mRNA are expressed in multiple organs as revealed by qualitative RT-PCR analysis. Furthermore, quantitative reverse transcription polymerase chain reaction analysis revealed that AamAch-L mRNA was downregulated in the mid-gut, but was unchanged in the salivary gland and in other organs in response to feeding. Of significant interest, AamAch-L and/or AamAch-S functions are probably associated with formation and/or maintenance of stability of A. americanum tick cement cone. Dual RNA interference silencing of AamAch-L and/or AamAch-S mRNA caused ticks to loosely attach onto host skin as suggested by bleeding around tick mouthparts and ticks detaching off host skin with a light touch. AamAch-L may apparently encode an inactive chitinase as indicated by Pichia pastoris-expressed recombinant AamAch-L failing to hydrolyse chitinase substrates. Unpublished related work in our laboratory, and published work by others that found AamAch-L in tick saliva, suggest that native AamAch-L is a non-specific immunoglobulin binding tick saliva protein in that rAamAch-L non-specifically bound rabbit, bovine and chicken non-immune sera. We discuss findings in this study with reference to advancing knowledge on tick feeding physiology. PMID:25189365

    It is shown that in the interference of multiple laser pulses with a relativistic intensity, phase and amplitude fronts of which are tilted at an angle with respect to their wave vector, effective traps of charged particles, which are moving at the velocity of light, are formed. Such traps are capable of capturing and accelerating the electrons produced in the ionisation of low-density gas by means of laser radiation. The accelerated electrons in the traps form a bunch, whose dimensions in all directions are much smaller than the laser radiation wavelength. Calculations show that the energy of accelerated electrons may amount to several hundred GeV at experimentally accessible relativistic laser intensities. As a result of the inverse Compton scattering, gamma-quanta with a high energy and narrow radiation pattern are emitted when these electrons interact with a laser pulse propagating from the opposite direction. The duration of emitted gamma-ray pulses constitutes a few attoseconds. The simulation is performed by solving the relativistic equation of motion for an electron with a relevant Lorentz force.

    Hematopoietic stem cells (HSCs) can survive long-term in a state of dormancy. Little is known about how histone deacetylase inhibitors (HDACi) affect HSC kinetics. Here, we use trichostatin A (TSA), a histone deacetylase inhibitor, to enforce histone acetylation and show that this suppresses cell cycle entry by dormant HSCs. Previously, we found that haploinsufficiency of PSF1, a DNA replication factor, led to attenuation of the bone marrow (BM) HSC pool size and lack of acute proliferation after 5-FU ablation. Because PSF1 protein is present in CD34{sup +} transiently amplifying HSCs but not in CD34{sup −} long-term reconstituting-HSCs which are resting in a dormant state, we analyzed the relationship between dormancy and PSF1 expression, and how a histone deacetylase inhibitor affects this. We found that CD34{sup +} HSCs produce long functional PSF1 (PSF1a) but CD34{sup −} HSCs produce a shorter possibly non-functional PSF1 (PSF1b, c, dominantly PSF1c). Using PSF1a-overexpressing NIH-3T3 cells in which the endogenous PSF1 promoter is suppressed, we found that TSA treatment promotes production of the shorter form of PSF1 possibly by inducing recruitment of E2F family factors upstream of the PSF1 transcription start site. Our data document one mechanism by which histone deacetylase inhibitors affect the dormancy of HSCs by regulating the DNA replication factor PSF1. - Highlights: • Hematopoetic stem cell dormancy is controlled by histone deacetylation inhibitors. • Dormancy of HSCs is associated with a shorter form of non-functional PSF1. • Histone deacetylase inhibitors suppress PSF1 promoter activity.

  10. Perception and the strongest sensory memory trace of multi-stable displays both form shortly after the stimulus onset.

    2016-02-01

    We investigated the relation between perception and sensory memory of multi-stable structure-from-motion displays. The latter is an implicit visual memory that reflects a recent history of perceptual dominance and influences only the initial perception of multi-stable displays. First, we established the earliest time point when the direction of an illusory rotation can be reversed after the display onset (29-114 ms). Because our display manipulation did not bias perception towards a specific direction of illusory rotation but only signaled the change in motion, this means that the perceptual dominance was established no later than 29-114 ms after the stimulus onset. Second, we used orientation-selectivity of sensory memory to establish which display orientation produced the strongest memory trace and when this orientation was presented during the preceding prime interval (80-140 ms). Surprisingly, both estimates point towards the time interval immediately after the display onset, indicating that both perception and sensory memory form at approximately the same time. This suggests a tighter integration between perception and sensory memory than previously thought, warrants a reconsideration of its role in visual perception, and indicates that sensory memory could be a unique behavioral correlate of the earlier perceptual inference that can be studied post hoc.

    Enhanced water window x-ray emission (23–44 Å) from carbon clusters, formed in situ using a pre-pulse, irradiated by intense (I > 10{sup 17} W/cm{sup 2}) ultra-short laser pulse, is demonstrated. An order of magnitude x-ray enhancement over planar graphite target is observed in carbon clusters, formed by a sub-ns pre-pulse, interacting with intense main pulse after a delay. The effect of the delay and the duration of the main pulse is studied for optimizing the x-ray emission in the water window region. This x-ray source has added advantages of being an efficient, high repetition rate, and low debris x-ray source.

Design Using a mixed-methods design, we developed and tested a Psychological Trauma item bank with patient and provider focus groups, cognitive interviews, and item response theory based analytic approaches, including tests of model fit, differential item functioning (DIF) and precision. Setting We tested a 31-item pool at several medical institutions across the United States, including the University of Michigan, Kessler Foundation, Rehabilitation Institute of Chicago, the University of Washington, Craig Hospital and the James J. Peters/Bronx Veterans Administration hospital. Participants A total of 716 individuals with SCI completed the trauma items Results The 31 items fit a unidimensional model (CFI=0.952; RMSEA=0.061) and demonstrated good precision (theta range between 0.6 and 2.5). Nine items demonstrated negligible DIF with little impact on score estimates. The final calibrated item bank contains 19 items Conclusion The SCI-QOL Psychological Trauma item bank is a psychometrically robust measurement tool from which a short form and a computer adaptive test (CAT) version are available.

    Objective To describe the development and psychometric properties of the Spinal Cord Injury - Quality of Life (SCI-QOL) Resilience item bank and short form. Design Using a mixed-methods design, we developed and tested a resilience item bank through the use of focus groups with individuals with SCI and clinicians with expertise in SCI, cognitive interviews, and item-response theory based analytic approaches, including tests of model fit and differential item functioning (DIF). Setting We tested a 32-item pool at several medical institutions across the United States, including the University of Michigan, Kessler Foundation, the Rehabilitation Institute of Chicago, the University of Washington, Craig Hospital and the James J. Peters/Bronx Department of Veterans Affairs medical center. Participants A total of 717 individuals with SCI completed the Resilience items. Results A unidimensional model was observed (CFI = 0.968; RMSEA = 0.074) and measurement precision was good (theta range between −3.1 and 0.9). Ten items were flagged for DIF, however, after examination of effect sizes we found this to be negligible with little practical impact on score estimates. The final calibrated item bank resulted in 21 retained items. Conclusion This study indicates that the SCI-QOL Resilience item bank represents a psychometrically robust measurement tool. Short form items are also suggested and computer adaptive tests are available. PMID:26010971

    The purpose of this study was to examine the reliability and validity of a Japanese short form of the Swanson Cognitive Processing Test, which assesses capacity of working memory. Test-retest reliability was acceptable (r = .76). Concurrent validity was suggested through comparison of scores on the Reading Span Task (r = .55). Means on the Japanese short form were comparable with means for the 3 subtests for the older group and 2 subtests for the younger group. With the exception of the Auditory Digit Sequence, results suggested that both the Japanese short form and the initial Swanson Cognitive Processing Test measured comparably the working memory in the two samples of children.

    The study tested the cross-linguistic validity of the Very Short form of the Physical Self-Inventory (PSI-VS) among 1115 Flemish (Dutch version) adolescents, and a comparison sample of 1103 French adolescents (French version; from Morin & Maïano, 2011a). Flemish adolescents also completed a positively worded reformulation of the reverse-keyed item of the physical attractiveness (PA) subscale. Confirmatory factor analyses (CFA) supported the factor validity and reliability (except for the Dutch PA subscale) of the PSI-VS, and its partial measurement invariance across samples. CFA conducted on the modified version of the Dutch PSI-VS (11 original items plus the positively worded replacement), presented satisfactory reliability (ω=.67-.89), and was fully invariant across sexes, age groups, and body mass index categories. Additionally, results revealed latent mean differences across sexes and body mass index categories. Therefore, the modified Dutch PSI-VS can be used whenever there is a need for a very short physical self-concept questionnaire. PMID:26057984

    The Brief Pain Inventory (BPI) is a widely used pain measurement tool. There are 2 versions, the BPI Long Form (BPI-LF) and Short Form (BPI-SF), which share 2 core scales measuring pain severity and pain interference but which use different recall periods (24 hours vs. 1 week). To date, the BPI-SF has not been validated for use in Spain. This study investigated the psychometric properties of the BPI-SF Spanish version and compared results on the core scales between BPI-LF and BPI-SF. The data came from a 3-month observational study of 3,029 nononcologic patients managed in Spanish pain units. The BPI-SF's reliability, validity, and responsiveness were assessed. The effect of different recall periods was investigated by using intraclass correlation coefficients (ICCs) to determine the strength of correlation between BPI-LF and BPI-SF. The BPI-SF showed good reliability, with Cronbach's alphas of 0.931 for the severity and interference scales, which also discriminated well between patients reporting different levels of quality of life on EuroQol-5D dimensions (between group effect sizes [ESs] over 0.8). Substantial improvements were seen on both subscales after 3 months of treatment (ES of 1.76 for pain severity and 1.51 for pain interference). Recall period did not noticeably affect scores; ICCs (95% CI) between the long and short versions were 0.946 (0.938 to 0.954) and 0.929 (0.919 to 0.939) for the severity and interference subscales, respectively. The Spanish version of the BPI-SF is a valid and reliable instrument to measure pain severity and interference. PMID:24766769

    Background Quality of life (QoL) of patients has become a central evaluation parameter that also acts as an aid for decisions related to treatment strategies particularly for patients with chronic illnesses. In Germany, one of the newer instruments attempting to measure distinct QoL aspects is the "Herdecke Questionnaire for Quality of Life" (HLQ). In this study, we aimed to validate the HLQ with respect to its factorial structure, and to develop a short form. The validation has been carried out in relation to other questionnaires including the SF-36 Health Survey, the Mood-Scale Bf-S, the Giessen Physical Complaints Questionnaire GBB-24 and McGill's Pain Perception Scale SES. Methods Data for this study derived from a model project on the treatment of patients using naturopathy methods in Blankenstein Hospital, Hattingen. In total, 2,461 patients between the ages of 16 and 92 years (mean age: 58.0 ± 13.4 years) were included in this study. Most of the patients (62%) suffered from rheumatic diseases. Factorial validation of the HLQ, it's reliability and external consistency analysis and the development of a short form were carried out using the SPSS software. Results Structural analysis of the HLQ-items pointed to a 6-factor model. The internal consistency of both the long and the short version is excellent (Cronbach's α is 0.935 for the HLQ-L and 0.862 for the HLQ-S). The highest reliability in the HLQ-L was obtained for the "Initiative Power and Interest" scale, the lowest for the 2-item scales "Digestive Well-Being" and the "Physical Complaints". However, the scales found by factor analysis herein were only in part congruent with the original 5-scale model which was approved a multitrait analysis approach. The new instrument shows good correlations with several scales of other relevant QoL instruments. The scales "Initiative Power and Interest", "Social Interaction", "Mental Balance", "Motility", "Physical Complaints", "Digestive Well-Being" sufficiently

    On May 5, 2006 a four-second duration, low-energy, approximately 10(exp 59) erg, Gamma-Ray Burst (GRB) was observed, spatially associated with a z=0.0894 galaxy. Here, we report the discovery of the GRB optical afterglow and observations of its environment using gemini-south, Hubble Space Telescope (HST), Chandra, Swift and the Very Large Array. The optical afterglow of this GRB is spatially associated with a prominent star forming region in the Sc-type galaxy 2dFGRS S173Z112. Its proximity to a star forming region suggests that the progenitor delay time, from birth to explosion, is smaller than about 10 Myr. Our HST deep imaging rules out the presence of a supernova brighter than an absolute magnitude of about -11 (or -126 in case of 'maximal' extinction) at about two weeks after the burst, and limits the ejected mass of radioactive Nickel 56 to be less than about 2x10(exp -4) solar mass (assuming no extinction). Although it was suggested that GRB 060505 may belong to a new class of long-duration GRBs with no supernova, we argue that the simplest interpretation is that the physical mechanism for this burst is the same as for short-duration GRBs.

    Abbreviated versions of the Wechsler Adult Intelligence Scale-Revised (WAIS-R) have been developed as time saving devices that provide accurate estimates of overall level of general intellectual functioning while decreasing test administration time. The Satz-Mogel short form of the WAIS-R has received substantial attention in the literature as an accurate measure of intellectual functions when compared with the Full WAIS-R. However, most studies comparing the Satz-Mogel version to the Full WAIS-R have only provided correlational analyses. Our study was an attempt to apply a more rigorous statistical methodology in determining if the Full WAIS-R and abbreviated versions are equivalent. We explored the impact of level of global mental status and age on the Satz-Mogel version. Although the two forms of the test correlated highly, repeated measures design indicated significant differences between Satz-Mogel and Full WAIS-R when participants were divided into groups based on level of global impairment and age. Our results suggest that the Satz-Mogel version of the test may not be equivalent to the full WAIS-R and is likely to misrepresent a patient's level of intellectual functioning, particularly for patients with progressive degenerative conditions. The implications of applying Satz-Mogel scoring to the Wechsler Adult Intelligence Scale-III (WAIS-III) are discussed. PMID:11094390

    The Noise Sensitivity Scale Short Form (NSS-SF), developed in English as a more practical form of the classical Weinstein NSS, has not to date been validated in other cultures, and its validity and reliability have not yet been confirmed. This study aimed to validate NSS-SF in Bulgarian and to demonstrate its applicability. The study comprised test-retest (n = 115) and a field-testing (n = 71) of the newly validated scale. Its construct validity was examined with confirmatory factor analysis, and very good model-fit was observed. Temporal stability was assessed in a test-retest (r = 0.990), convergent validity was examined with single-item susceptibility to the noise scale (r = 0.906) and discriminant validity was confirmed with single-item noise annoyance scale (r = 0.718). The lowest observed McDonald's omega across the studies was 0.923. The cross-cultural validation of NSS-SF was successful but it proved to be somewhat problematic with respect to its annoyance-based items. PMID:25387531

    The oxidation of Fe(II) in water leads to the formation of Fe(III)-precipitates that strongly affect the fate of nutrients and contaminants in natural and engineered systems. Examples include the cycling of As in rice fields irrigated with As-rich groundwater or the treatment of drinking water for As removal. Knowledge of the types of Fe(III)-precipitates forming in such systems is essential for the quantitative modeling of nutrient and contaminant dynamics and for the optimization of water purification techniques on the basis of a mechanistic understanding of the relevant biogeochemical processes. In this study, we investigated the local coordination of Fe, P, and Ca in Fe(III)-precipitates formed by aeration of synthetic Fe(II)-containing groundwater with variable composition (pH 7, 2-30 mg/L Fe(II), 2-20 mg/L phosphate-P, 2-20 mg/L silicate-Si, 8 mM Na-bicarbonate or 2.5 mM Ca-&1.5 mM Mg-bicarbonate). After 4 hours of oxidation, Fe(III)-precipitates were collected on 0.2 µm nylon filters and dried. The precipitates were analyzed by Fe K-edge EXAFS (XAS beamline, ANKA, Germany) and by P and Ca K-edge XANES spectroscopy (LUCIA beamline, SLS, Switzerland). The Fe K-edge EXAFS spectra indicated that local Fe coordination in the precipitates systematically shifted with water composition. As long as water contained P, mainly short-range-ordered Fe(III)-phosphate formed (with molar P/Fe ~0.5). In the absence of P, Fe(III) precipitated as hydrous ferric oxide at high Si/Fe>0.5, as ferrihydrite at intermediate Si/Fe, and mainly as lepidocrocite at Si/Fe<0.2. Analysis of the EXAFS by shell-fitting indicated that Fe(III)-phosphates mainly contained mono- or oligomeric (edge- or corner-sharing) Fe and that the linkage between neighboring Fe(III)-octahedra changed from predominantly edge-sharing in Si-rich hydrous ferric oxide to edge- and corner-sharing in ferrihydrite. Electron microscopic data showed that changes in local precipitate structure were systematically

    Background The Physical Activity and Sedentary Behaviour Assessment Questionnaire (PASBAQ), used within the Health Survey for England (HSE) at 5-yearly intervals, is not included annually due to funding and interview-length constraints. Policy-makers and data-users are keen to consider shorter instruments such as the Short-form International Physical Activity Questionnaire (IPAQ) for the annual survey. Both questionnaires were administered in HSE 2012, enabling comparative assessment in a random sample of 1252 adults. Methods Relative agreement using prevalence-adjusted bias-adjusted Kappa (PABAK) statistics was estimated for: sufficient aerobic activity (moderate-to-vigorous physical activity [MVPA] ≥150minutes/week); inactivity (MVPA<30minutes/week); and excessive sitting (≥540minutes/weekday). Cross-sectional associations with health outcomes were compared across tertiles of MVPA and tertiles of sitting time using logistic regression with tests for linear trend. Results Compared with PASBAQ data, IPAQ-assessed estimates of sufficient aerobic activity and inactivity were higher and lower, respectively; estimates of excessive sitting were higher. Demographic patterns in prevalence were similar. Agreement using PABAK statistics was fair-to-moderate for sufficient aerobic activity (0.32–0.49), moderate-to-substantial for inactivity (0.42–0.74), and moderate-to-substantial for excessive sitting (0.49–0.75). As with the PASBAQ, IPAQ-assessed MVPA and sitting each showed graded associations with mental well-being (women: P for trend = 0.003 and 0.004, respectively) and obesity (women: P for trend = 0.007 and 0.014, respectively). Conclusions Capturing habitual physical activity and sedentary behaviour through brief questionnaires is complex. Differences in prevalence estimates can reflect differences in questionnaire structure and content rather than differences in reported behaviour. Treating all IPAQ-assessed walking as moderate-intensity contributed to the

    CheA is the histidine protein kinase of a two-component signal transduction system required for bacterial chemotaxis. Motile cells of the enteric species Escherichia coli and Salmonella typhimurium synthesize two forms of CheA by utilizing in-frame initiation sites within the gene cheA. The full-length protein, CheAL, plays an essential role in the chemotactic signaling pathway. In contrast, the function of the short form, CheAs, remains elusive. Although CheAs lacks the histidine residue that becomes phosphorylated in CheAL, it exhibits both kinase activity and the ability to interact with and enhance the activity of CheZ, a chemotaxis protein that accelerates dephosphorylation of the two-component response regulator CheY. To determine whether other members of the family Enterobacteriaceae express CheAs and CheZ, we analyzed immunoblots of proteins from clinical isolates of a variety of enteric species. All motile, chemotactic isolates that we tested coexpressed CheAL, CheAs, and CheZ. The only exceptions were closely related plant pathogens of the genus Erwinia, which expressed CheAL and CheZ but not CheAs. We also analyzed nucleotide sequences of the cheA loci from isolates of Serratia marcescens and Enterobacter cloacae, demonstrating the presence of in-frame translation initiation sites similar to those observed in the cheA loci of E. coli and S. typhimurium. Since coexpression of CheAs and CheZ appears to be limited to motile, chemotactic enteric bacteria, we propose that CheAs may play an important role in chemotactic responses in some environmental niches encountered by enteric species.

Next, 50 patients with primary hip osteoarthritis were asked to fill out the Turkish version of the HOOS-PS two times with one week interval. Internal consistency was tested using the Cronbach's alpha coefficient, and test-retest reliability was assessed by calculating the intra-class correlation coefficient (ICC). Construct validity was investigated by comparing the results of the HOOS-PS and WOMAC, Lequesne questionnaries using Spearman's rank correlation coefficient. Internal consistency was good with a Cronbach's alpha of 0.778 (>0.7) and ICC was 0.911 (>0.7). Both scores verify that the Turkish HOOS-PS is a reliable tool. Spearman's rank correlation coefficients between the HOOS-PS and overall WOMAC (r = 0.653), WOMAC physical functions (r = 0.626), WOMAC pain (r = 0.629) subscales, overall Lequesne (r = 0.650), and Lequesne daily living activities (r = 0.620) subscales were high (r > 0.6), and moderate correlations were found between the HOOS-PS and WOMAC stiffness (r = 0.511), Lequesne pain (r = 0.569), and Lequesne-walking distance (r = 0.578) subscales (0.6 > r > 0.2), thus providing proof for the validity of the Turkish form. The Turkish HOOS-PS was found to be reliable and valid for patients with primary hip osteoarthritis. PMID:24026527

    Objective To develop a calibrated item bank and computer adaptive test (CAT) to assess the effects of stigma on health-related quality of life in individuals with spinal cord injury (SCI). Design Grounded-theory based qualitative item development methods, large-scale item calibration field testing, confirmatory factor analysis, and item response theory (IRT)-based psychometric analyses. Setting Five SCI Model System centers and one Department of Veterans Affairs medical center in the United States. Participants Adults with traumatic SCI. Main Outcome Measures SCI-QOL Stigma Item Bank Results A sample of 611 individuals with traumatic SCI completed 30 items assessing SCI-related stigma. After 7 items were iteratively removed, factor analyses confirmed a unidimensional pool of items. Graded Response Model IRT analyses were used to estimate slopes and thresholds for the final 23 items. Conclusions The SCI-QOL Stigma item bank is unique not only in the assessment of SCI-related stigma but also in the inclusion of individuals with SCI in all phases of its development. Use of confirmatory factor analytic and IRT methods provide flexibility and precision of measurement. The item bank may be administered as a CAT or as a 10-item fixed-length short form and can be used for research and clinical applications. PMID:26010973

    The current study reports the development from the Male Role Norms Inventory-Revised (MRNI-R; Levant, Rankin, Williams, Hasan, & Smalley, 2010) of the 21-item MRNI-Short Form (MRNI-SF). Confirmatory factor analysis of MRNI-SF responses from a sample of 1,017 undergraduate participants (549 men, 468 women) indicated that the best fitting "bifactor" model incorporated the hypothesized 7-factor structure while explicitly modeling an additional, general traditional masculinity ideology factor. Specifically, each item-level indicator loaded on 2 factors: a general traditional masculinity ideology factor and a specific factor corresponding to 1 of the 7 hypothesized traditional masculinity ideology norms. The bifactor model was assessed for measurement invariance across gender groups, with findings of full configural invariance and partial metric invariance, such that factor loadings were equivalent across the gender groups for the 7 specific factors but not for the general traditional masculinity ideology factor. Theoretical explanations for this latter result include the potential that men's sense of self or identity may be engaged when responding to questions asking to what extent they agree or disagree with normative statements about their behavior, a possibility that could be investigated in future research by examining the associations of the general and specific factors with measures of masculine identity. Additional exploratory invariance analyses demonstrated latent mean differences between men and women on 4 of the 8 factors, and equivocal results for invariance of item intercepts, item uniquenesses, and factor variances-covariances.

    Objective To develop an item response theory (IRT) calibrated Grief and Loss item bank as part of the Spinal Cord Injury – Quality of Life (SCI-QOL) measurement system. Design A literature review guided framework development of grief/loss. New items were created from focus groups. Items were revised based on expert review and patient feedback and were then field tested. Analyses included confirmatory factor analysis (CFA), graded response IRT modeling and evaluation of differential item functioning (DIF). Setting We tested a 20-item pool at several rehabilitation centers across the United States, including the University of Michigan, Kessler Foundation, Rehabilitation Institute of Chicago, the University of Washington, Craig Hospital and the James J. Peters/Bronx Department of Veterans Affairs hospital. Participants A total of 717 individuals with SCI answered the grief and loss questions. Results The final calibrated item bank resulted in 17 retained items. A unidimensional model was observed (CFI = 0.976; RMSEA = 0.078) and measurement precision was good (theta range between −1.48 to 2.48). Ten items were flagged for DIF, however, after examination of effect sizes found this to be negligible with little practical impact on score estimates. Conclusions This study indicates that the SCI-QOL Grief and Loss item bank represents a psychometrically robust measurement tool. Short form items are also suggested and computer adaptive tests are available. PMID:26010969

    We examined the psychometric qualities of the Short Form of the Coopersmith Self-Esteem Inventory (SF-CSEI) in a large sample of French adolescents and young adults. A 25-item French version was administered to 1,362 participants (561 aged below 16 years and 801 aged 16-25 years). Participants also completed other scales to measure construct validity (e.g., Rosenberg Self-Esteem Scale, Hospital Anxiety and Depression Scale, and General Health Questionnaire). Factorial analysis yielded evidence for a structure with three first-order factors for the SF-CSEI: personal, social, and family-derived self-esteem. The internal consistency of the questionnaire's different dimensions was satisfactory (Cronbach's α = .68-.77). Pearson's correlation coefficients showed that the SF-CSEI had moderate to high correlations with convergent measures (r = .19-.73) and constructs related to self-esteem (r = -.23-.65). Psychiatric patients (n = 67) scored significantly lower than a control group. Test-retest reliability was good for some of the factors, especially at 5 weeks and 1 year (r = .29-.79). The French version of the SF-CSEI appears to be a useful instrument, with a cross-culturally stable factorial structure. PMID:25655375

    The approach proposed in the 70s (Dementiji et al. in Sov J Nucl Phys 22:6-9, 1976), when describing the elastic and inelastic electron scattering off 4 He, and elaborated in (Shebeko et al.in Eur Phys J A27:143-155, 2006) for calculations of the one-body, two-body and more complex density matrices of finite bound systems has been applied (Shebeko and Grigorov in Ukr J Phys 52:830-842, 2007; Shebeko et al. in Eur. Phys. J. A48:153-172, 2012) in studying a combined effect of the center-of-mass motion and nucleon-nucleon short-range correlations on the nucleon density and momentum distributions in light nuclei beyond the independent particle model. Unlike a common practice, suitable for infinite bound systems, these distributions are determined as expectation values of appropriate intrinsic operators that depend upon the relative coordinates and momenta (Jacobi variables) and act on the intrinsic ground-state wave functions (WFs). The latter are constructed in the so-called fixed center-of-mass approximation, starting with a mean-field Slater determinant modified by some correlator (e.g., after Jastrow or Villars). Our numerical calculations of the charge form factors ( F CH ( q)), densities and momentum distributions have been carried out for nuclei 4 He and 16 O choosing, respectively, the 1 s and 1 s-1 p Slater determinants of the harmonic oscillator model as trial, nontranslationally invariant WFs.

    A decrease in the level of engagement in activities ("behavioral activation") is usually observed in major depressive disorder. Because behavioral treatments of depression aim to counteract that mechanism, assessing changes in behavioral activation during treatment is of great interest. Therefore, Manos et al. (2011) developed a scale that assesses these changes, which was called the Behavioral Activation for Depression Scale-Short Form (BADS-SF). The aim of this study is to present a French version of this scale and to discuss its psychometric properties. The BADS-SF was translated into French, and 504 non-clinical adults completed an online survey that was composed of that scale and convergent measures. Exploratory and confirmatory factor analyses were performed in two independent samples, and a two-factor solution was recommended, which references two functions of the engagement in activities (i.e., "activation" and "avoidance"). The results showed high levels of internal consistency and satisfying scores in terms of skewness and kurtosis. Moreover, relationships with measures of depression and behavioral systems indicated a good convergent validity. Therefore, the French BADS-SF can be seen as a reliable and valid instrument.

    For the purpose of retrospective assessment and characterization of childhood trauma in adults, the factorial validity of the short form of the Childhood Trauma Questionnaire (CTQ-SF) in Germany was evaluated by conducting confirmatory factor analyses for three samples including 1,524 adult psychiatric patients, 224 inmates, and 295 university students. In addition, sex-specific confirmatory factor analyses were performed within each sample. Because several authors have suggested a different factor structure than that originally proposed in the manual, two competing models focusing on the Physical neglect subscale were examined. In psychiatric patients and inmates, the fit indices were reasonable to good. Among the students, factor loadings were markedly lower, and fit indices were poor. Sex-specific analyses did not indicate sex differences. Comparing the original and the alternative models revealed better fit indices of the original factor structure. The present findings indicate that the German version of the CTQ-SF has factorial validity in psychiatric patients and inmates, but not in students. PMID:25933042

    The rise and growing popularity of online games has led to the appearance of excessive gaming that in some cases can lead to physical and psychological problems. Several measures have been developed to explore the nature and the scale of the phenomenon. However, few measures have been validated psychometrically. The aim of the present study was to test the psychometric properties of the 12-item Problematic Online Gaming Questionnaire Short-Form (POGQ-SF) and to assess the prevalence of problematic online gaming. Data collection was carried out to assess the prevalence of problematic online gaming in a national representative adolescent sample by using an offline (pen and pencil) method. A total of 5,045 secondary school students were assessed (51% male, mean age 16.4 years, SD=0.9 years) of which 2,804 were gamers (65.4% male, mean age 16.4 years, SD=0.9 years). Confirmatory factor analysis was applied to test the measurement model of problematic online gaming, and latent profile analysis was used to identify the proportion of gamers whose online game use can be considered problematic. Results showed that the original six-factor model yielded appropriate fit to the data, and thus the POGQ-SF has appropriate psychometric properties. Latent profile analysis revealed that 4.6% of the adolescents belong to a high risk group and an additional 13.3% to a low risk group. Due to its satisfactory psychometric characteristics, the 12-item POGQ-SF appears to be an adequate tool for the assessment of problematic online gaming. PMID:23621688

    The 36-item short-form health survey (SF-36) is one of the most commonly used health status instruments in patients with cerebrovascular disease. However, responsiveness to change in health-related quality of life (HRQoL) has not yet been assessed for the SF-36 and its shortened version, the SF-12. The main objective of the present study was to determine responsiveness to change of the SF-12 in patients with cerebrovascular disease. Patients with stroke/transient ischaemic attack (TIA) were included at admission to one of four participating hospitals. HRQoL was assessed with the Physical (PCS-12) and Mental (MCS-12) Component Summary scales at baseline (referring to the status prior to the event) and after 12 months. Responsiveness to change was determined with the standardized response mean (SRM) and classified as small (SRM 0.20-0.49), moderate (0.50-0.79) or large (> or =0.80). A total of 558 patients were included [55% men, mean age 65 (SD, 13) years; 45% women, mean age 69 (SD, 14) years]. Indications for admission were stroke (74%) and TIA (26%). In patients with stroke, SRMs were small for the PCS-12 [SRM 0.49; absolute change -5.9 (SD, 12)] and moderate for the MCS-12 [SRM 0.52; absolute change -6.6 (SD, 13)]. In patients with TIA, SRMs were below 0.2 for the PCS-12 [absolute change -0.7 (SD, 11)] and small for the MCS-12 [SRM 0.34; absolute change -3.7 (SD, 11)]. SRMs increased with stroke severity as indicated by the NIHSS score. The SF-12 summary scales showed a small to moderate responsiveness to change in patients after stroke. Responsiveness to change was higher in patients with increased symptom severity. PMID:15802924

    Methylmercury (MeHg) has been previously shown to affect neurotransmitter release. Short-term synaptic plasticity (STP) is primarily related to changes in the probability of neurotransmitter release. To determine if MeHg affects STP development, we examined STP forms in the visual cortex of rat following in vivo MeHg exposure. Neonatal rats received 0 (0.9% NaCl), 0.75 or 1.5 mg/kg/day MeHg subcutaneously for 15 or 30 days beginning on postnatal day 5, after which visual cortical slices were prepared for field potential recordings. In slices prepared from rats treated with vehicle, field excitatory postsynaptic potentials (fEPSPs) evoked by paired-pulse stimulation at 20-200 ms inter-stimulus intervals showed a depression (PPD) of the second fEPSP (fEPSP2). PPD was also seen in slices prepared from rats after 15 day treatment with 0.75 or 1.5 mg/kg/day MeHg. However, longer duration treatment (30 days) with either dose of MeHg resulted in paired-pulse facilitation (PPF) of fEPSP2 in the majority of slices examined. PPF remained observable in slices prepared from animals in which MeHg exposure had been terminated for 30 days after completion of the initial 30 day MeHg treatment, whereas slices from control animals still showed PPD. MeHg did not cause any frequency- or region-preferential effect on STP. Manipulations of [Ca{sup 2+}]{sub e} or application of the GABA{sub A} receptor antagonist bicuculline could alter the strength and polarity of MeHg-induced changes in STP. Thus, these data suggest that low level postnatal MeHg exposure interferes with the developmental transformation of STP in the visual cortex, which is a long-lasting effect.

    Abstract Objective: The purpose of this study was to evaluate the efficacy of once-daily guanfacine extended release (GXR) monotherapy administered either in the morning or evening, using a modified Conners' Parent Rating Scale–Revised: Short Form (CPRS–R:S) assessed three times/day in children with attention-deficit/hyperactivity disorder (ADHD). Methods: This multicenter, double-blind, placebo-controlled study randomized children 6–12 years of age with ADHD into three groups: GXR a.m. (GXR in the morning and placebo in the evening), GXR p.m. (placebo in the morning and GXR in the evening), or twice-daily placebo. The CPRS–R:S, administered in the morning, afternoon, and evening prior to each study visit, was a secondary measure of efficacy. Results: A total of 333 subjects were included in the analysis population (GXR a.m., n=107; GXR p.m., n=114; placebo, n=112). At visit 10, last observation carried forward (LOCF), subjects receiving GXR demonstrated significantly greater improvement from baseline in the daily mean CPRS–R:S total score, as well as in each of the morning, afternoon, and evening CPRS–R:S assessments, compared with placebo, regardless of the time of GXR administration (p<0.001 vs. placebo for GXR a.m. and GXR p.m.). In addition, subjects receiving GXR showed significantly greater improvements from baseline in each subscale score (oppositional, cognitive problems/inattention, hyperactivity, and ADHD index) compared with those receiving placebo, regardless of time of administration (p<0.003 vs. placebo across all subscales for GXR a.m. and GXR p.m.). Conclusions: These results provide further support for the demonstrated efficacy of once-daily GXR in reducing ADHD symptoms, and demonstrate that response is consistent throughout the day regardless of the time of administration, with improvement seen in ratings of oppositional as well as of ADHD symptoms.

    Background: To test the psychometric properties of the Persian version of Zarit Burden Interview (ZBI-12) in the Iranian population. Methods: After translating and cultural adaptation of the questionnaire into Persian, 100 caregiver spouses of Iran- Iraq war (1980-88) veterans with chronic spinal cord injury who live in the city of Mashhad, Iran, invited to participate in the study. The Persian version of ZBI-12 accompanied with the Persian SF-36 was completed by the caregivers to test validity of the Persian ZBI-12.A Pearson`s correlation coefficient was calculated for validity testing. In order to assess reliability of the Persian ZBI-12, we administered the ZBI-12 randomly in 48 caregiver spouses again 3 days later. Results: Generally, the internal consistency of the questionnaire was found to be strong (Cronbach's alpha 0.77). Intercorrelation matrix between the different domains of ZBI-12 at test-retest was 0.78. The results revealed that majority of questions the Persian ZBI_12 have a significant correlation to each other. In terms of validity, our results showed that there is significant correlations between some domains of the Persian version the Short Form Health Survey -36 with the Persian Zarit Burden Interview such as Q1 with Role Physical (P=0.03),General Health (P=0.034),Social Functional (0.037), Mental Health (0.023) and Q3 with Physical Function (P=0.001),Viltality (0.002), Socil Function (0.001). Conclusions: Our findings suggest that the Zarit Burden Interview Persian version is both a valid and reliable instrument for measuring the burden of caregivers of individuals with chronic spinal cord injury.

    Objective To evaluate the validity and reliability of the Philippines (Tagalog) Short Form 36 Health Survey version 2 (SF-36v2®) standard questionnaire among Filipinos residing in two cities. Study Design and Setting The official Philippines (Tagalog) SF-36v2 standard (4-week recall) version was pretested on 30 participants followed by formal and informal cognitive debriefing. To obtain the feedback on translation by bilingual respondents, each SF-36v2 question was stated first in English followed by Tagalog. No revisions to the original questionnaire were needed except that participants thought it was appropriate to incorporate "po" in the instructions to make it more polite. Face-to-face interviews of 562 participants aged 20-50 years living in two barangays (villages) in the highly urbanized city of Makati City (Metro Manila) and in urban and rural barangays in Tanauan City (province of Batangas) were subsequently conducted. Content validity, item level validity, reliability and factor structure of the SF-36v2 (Tagalog) were examined. Results Content validity of the SF-36v2 was assessed to be adequate for assessing health status among Filipinos. Item means of Philippines (Tagalog) SF-36v2 were similar with comparable scales in the US English, Singapore (English and Chinese) and Thai SF-36 version 1. Item-scale correlation exceeded 0.4 for all items except the bathing item in PF (correlation: 0.31). In exploratory factor analysis, the US two-component model was supported. However, in confirmatory factor analysis, the Japanese three-component model fit the Tagalog data better than the US two-component model. Conclusions The Philippines (Tagalog) SF-36v2 is a valid and reliable instrument for measuring health status among residents of Makati City (Metro Manila) and Tanauan City (Province of Batangas).

    There are very few symptom assessment instruments in Chinese. We present the validity and reliability of the Memorial Symptom Assessment Scale Short Form (MSAS-SF) and the Condensed Form MSAS (CMSAS) in Chinese cancer patients. The Chinese version of the 32-item MSAS-SF, a self-report measure for assessing symptom distress and frequency in cancer patients, was administered to 256 Chinese patients with colorectal cancer at a clinical oncology outpatient unit. Highly prevalent symptoms included worrying (59%), dry mouth (54%), lack of energy (54%), feeling sad (48%), feeling irritable (48%), and pain (41%). Both the MSAS-SF and CMSAS demonstrated good validity and reliability. For the MSAS-SF subscales, Cronbach alphas ranged from 0.84 to 0.91, and for CMSAS subscales, from 0.79 to 0.87. Moderate-to-high correlations of MSAS-SF and CMSAS subscales with appropriate European Organization for Research and Treatment of Cancer (EORTC) QLQ-C30 subscales (0.42-0.71, Ps<0.001) indicated acceptable convergent validity. Low correlations with the Rosenberg Self-Esteem and Optimism Scale (0.22, P<0.001) indicated divergent validity. MSAS subscales varied as expected with other Chinese scales--the Chinese Health Questionnaire (CHQ) and the Life Orientation Scale. Construct validity of both MSAS versions was demonstrated by effective differentiation between clinically distinct patient groups (Karnofsky scores <80% vs. > or =80% [P<0.001]; no active treatment vs. active treatment [P<0.002-0.034]; CHQ-12 scores < or =4 vs. CHQ-12 scores >4 [P<0.001]). The Number of Symptoms subscale correlated appropriately with the EORTC QLQ-C30 function (-0.46 to -0.60, P<0.001) and symptom scales (0.31-0.64, P<0.001). The average time to complete the MSAS-SF was six minutes. The Chinese versions of the MSAS-SF and CMSAS are valid and practical measures. Further validation is needed for Chinese patients with other cancer types and with other symptom instruments. PMID:18434076

  4. Cultural adaptation and validation of the “Kidney Disease and Quality of Life - Short Form (KDQOL-SF™) version 1.3” questionnaire in Egypt

    Background Health Related Quality of Life (HRQOL) instruments need disease and country specific validation. In Arab countries, there is no specific validated questionnaire for assessment of HRQOL in chronic kidney disease (CKD) patients. The aim of this study was to present an Arabic translation, adaptation, and the subsequent validation of the kidney disease quality of life-short form (KDQOL-SFTM) version 1.3 questionnaire in a representative series of Egyptian CKD patients. Methods KDQOL-SFTM version 1.3 was translated into Arabic by two independent translators, and then subsequently translated back into English. After translation disparities were reconciled, the final Arabic questionnaire was tested by interviewing 100 pre-dialysis CKD (stage 1-4) patients randomly selected from outpatients attending the Nephrology clinic at the Main Alexandria University Hospital. Test re-test reliability was performed, with a subsample of 50 consecutive CKD patients, by two interviews 7 days apart and internal consistency estimated by Cronbach’s α. Discriminant, concept, and construct validity were assessed. Results All items of SF-36 met the criterion for internal consistency and were reproducible. Of the 10 kidney disease targeted scales, only three had Cronbach’s α <0.7: quality of social interaction (0.23), work status (0.28), and cognitive function (0.60). All disease specific scales were reproducible. Results from discriminant validity showed that the study questionnaire could discriminate between patients’ subgroups. As for concept validity, the correlation between all domains of the questionnaire with overall health ratewas significant for all domains except for the work status, sexual function, emotional wellbeing, and role emotional. Furthermore, the correlation between the disease specific domains and the two composite summaries of SF-36 (physical and mental composite summaries) was significant for all domains except for sexual function with mental composite

    A high-purity Fe-20Cr and commercial type 430 ferritic stainless steel were exposed at 700 and 800 C in dry air and air with 10% water vapor (wet air) and characterized by SEM, XRD, STEM, SIMS, and EPMA. The Fe-20Cr alloy formed a fast growing Fe-rich oxide scale at 700 C in wet air after 24 h exposure, but formed a thin chromia scale at 700 C in dry air and at 800 C in both dry air and wet air. In contrast, thin spinel + chromia base scales with a discontinuous silica subscale were formed on 430 stainless steel under all conditions studied. Extensive void formation was observed at the alloy-oxide interface for the Fe-20Cr in both dry and wet conditions, but not for the 430 stainless steel. The Fe-20Cr alloy was found to exhibit a greater relative extent of subsurface Cr depletion than the 430 stainless steel, despite the former's higher Cr content. Depletion of Cr in the Fe-20Cr after 24 h exposure was also greater at 700 C than 800 C. The relative differences in oxidation behavior are discussed in terms of the coarse alloy grain size of the high-purity Fe-20Cr material, and the effects of Mn, Si, and C on the oxide scale formed on the 430 stainless steel.

    An automotive fuel cell with an active area of 250 cm2 is investigated in a 4-cell short stack with a current and temperature distribution device next to the bipolar plate with 560 current and 140 temperature segments. The electrical conductivities of the bipolar plate and gas diffusion layer assembly are determined ex-situ with this current scan shunt module. The applied fuel cell consists of bipolar plates constructed of 75-μm-thick, welded stainless-steel foils and a graphitic coating. The electrical conductivities of the bipolar plate and gas diffusion layer assembly are determined ex-situ with this module with a 6% deviation in in-plane conductivity. The current density distribution is evaluated up to 2.4 A cm-2. The entire cell's investigated volumetric power density is 4.7 kW l-1, and its gravimetric power density is 4.3 kW kg-1 at an average cell voltage of 0.5 V. The current density distribution is determined without influencing the operating cell. In addition, the current density distribution in the catalyst-coated membrane and its effective resistivity distribution with a finite volume discretisation of Ohm's law are evaluated. The deviation between the current density distributions in the catalyst-coated membrane and the bipolar plate is determined.

    Formation of a diffuse discharge at a short front of voltage pulse (less than 1 ns), as well as when placing water, water solutions, and dielectric film inside the discharge, is studied. A volumetric discharge was observed in water on the anode when placing dielectric film (polyethylene, vinyl chloride-methyl methacrylate (VCMMA), etc.), water, or aqueous solutions of 3% hydrogen dioxide or 18% KMgO4 inside the discharge. The change in the absorption spectrum of substance was found after multiple discharge switching on. Fourier analysis of the infrared absorption spectra showed the difference between the spectra of exposed and unexposed polyethylene film. The changes in the absorption spectra of water, 3% hydrogen dioxide and 18% KMgO4 aqueous solutions are related with expansion of the band of valence oscillations of OH-groups without clearly expressed maxima (for the studied liquids). Therefore, volumetric diffuse discharge in molecular and atomic gases can be used in modifying dielectrics, water and aqueous solutions.

    Objective To examine test-retest reliability and internal consistency of the Children’s Social Desirability Short (S-CSD) scale, consisting of 14 items from the Children’s Social Desirability scale. Methods The previously validated S-CSD scale was classroom administered to 97 fourth-grade children (80% African American, 76% low socioeconomic status) in 2 sessions a month apart. Each classroom administration lasted approximately 5 minutes. Results The S-CSD scale showed acceptable levels of test-retest reliability (0.70) and internal consistency (0.82 and 0.85 for the first and second administrations, respectively). Reliability was adequate within subgroups of gender, socioeconomic status, academic achievement, and body mass index percentile. Levels of social desirability did not differ across subgroups. Conclusions and Implications Social desirability bias is a potential source of systematic response error in children’s self-report assessments of nutrition and health-related behaviors. The S-CSD scale may be used with diverse groups of children to reliably and efficiently assess social desirability bias. PMID:24418615

    Yiyeqing (“one night love”, i.e., having sex only once with a non-commercial partner) has increased in China, concomitant with the increase in heterosexual transmission of STI/HIV. Our study explored how participants who had experienced yiyeqing (YYQ) understood these relationships and characterized YYQ’s links to sexual risk behaviors. We conducted in-depth interviews with 45 adults in Liuzhou, a city in southwest China, who had YYQ experience. We analyzed the findings using social construction to interpret the participants’ understandings of YYQ. Participants reported that they tend to select YYQ partners whom they trust, which is built through introductions from social connections and within entertainment venues, resulting in the belief that their partners are free of STI/HIV and do not require protected sex. As YYQ relationships become more common, understanding the nature of these relationships is critical for developing public health messages that convey the risks associated with sex in short-term relationships and the need for condoms.

    Appearance-related disturbances are common among HIV-infected MSM; however, to date, there have been limited options in the valid assessment of this construct. The aim of the current study was to assess the structural, internal, and convergent validity of the assessment of body change distress questionnaire (ABCD) and its short version. Exploratory and confirmatory factor analyses indicated that both versions fit the data well. Four subfactors were revealed measuring the following body disturbance constructs: (1) negative affect about appearance, (2) HIV health-related outcomes and stigma, (3) eating and exercise confusion, and (4) ART non-adherence. The subfactors and total scores revealed bivariate associations with salient health outcomes, including depressive symptoms, HIV sexual transmission risk behaviors, and ART non-adherence. The ABCD and its short form, offer valid means to assess varied aspects of body image disturbance among HIV-infected MSM, and require modest participant burden. PMID:24057934

    Despite the large number of measurement tools developed to assess problematic Internet use, numerous studies use measures with only modest investigation into their psychometric properties. The goal of the present study was to validate the short (6-item) version of the Problematic Internet Use Questionnaire (PIUQ) on a nationally representative adolescent sample (n = 5,005; mean age 16.4 years, SD = 0.87) and to determine a statistically established cut-off value. Data were collected within the framework of the European School Survey Project on Alcohol and Other Drugs project. Results showed an acceptable fit of the original three-factor structure to the data. In addition, a MIMIC model was carried out to justify the need for three distinct factors. The sample was divided into users at-risk of problematic Internet use and those with no-risk using a latent profile analysis. Two latent classes were obtained with 14.4% of adolescents belonging to the at-risk group. Concurrent and convergent validity were tested by comparing the two groups across a number of variables (i.e., time spent online, academic achievement, self-esteem, depressive symptoms, and preferred online activities). Using the at-risk latent profile analysis class as the gold standard, a cut-off value of 15 (out of 30) was suggested based on sensitivity and specificity analyses. In conclusion, the brief version of the (6-item) PIUQ also appears to be an appropriate measure to differentiate between Internet users at risk of developing problematic Internet use and those not at risk. Furthermore, due to its brevity, the shortened PIUQ is advantageous to utilize within large-scale surveys assessing many different behaviors and/or constructs by reducing the overall number of survey questions, and as a consequence, likely increasing completion rates.

    Impulsivity is an important component of many forms of psychopathology. Though widely used as an index of this construct, the 30-item Barratt Impulsiveness Scale-11 (BIS-11) has demonstrated questionable psychometric properties in several research reports. An 8-item shortened version has recently been proposed, the Barratt Impulsiveness Scale-Brief (BIS-Brief) form, which was designed to overcome some of the limitations of the longer scale. In this report, we examine the internal structure and theoretically relevant external correlates of this new short form in large archival samples of individuals involved in the criminal justice system (prison inmates, substance abusers in mandatory treatment, and forensic inpatients). Confirmatory factor analysis of the BIS-Brief indicates adequate fit following a relatively minor modification. Correlations between the BIS-Brief and an array of criterion measures-other self-report scales, interview-based measures, and behavioral outcomes-are consistent with predictions and show relatively little or no decrement in predictive validity when compared with the 30-item BIS-11. Our results suggest that the BIS-Brief is a promising brief measure of impulsivity that evinces good psychometric properties across a range of offender samples. PMID:25894703

    Scoliosis Research Society-22 (SRS-22) questionnaire was developed to evaluate health-related quality of life (HRQL) in adolescent idiopathic scoliosis (AIS) patients. Rasch analysis (RA) is a statistical procedure which turns questionnaire ordinal scores into interval measures. Measures from Rasch-compatible questionnaires can be used, similar to body temperature or blood pressure, to quantify disease severity progression and treatment efficacy. Purpose of the current work is to present Rasch analysis (RA) of the SRS-22 questionnaire and to develop an SRS-22 Rasch-approved short form. 300 SRS-22 were randomly collected from 2447 consecutive IS adolescents at their first evaluation (229 females; 13.9 ± 1.9 years; 26.9 ± 14.7 Cobb°) in a scoliosis outpatient clinic. RA showed both disordered thresholds and overall misfit of the SRS-22. Sixteen items were re-scored and two misfitting items (6 and 14) removed to obtain a Rasch-compatible questionnaire. Participants HRQL measured too high with the rearranged questionnaire, indicating a severe SRS-22 ceiling effect. RA also highlighted SRS-22 multidimensionality, with pain/function not merging with self-image/mental health items. Item 3 showed differential item functioning (DIF) for both curve and hump amplitude. A 7-item questionnaire (SRS-7) was prepared by selecting single items from the original SRS-22. SRS-7 showed fit to the model, unidimensionality and no DIF. Compared with the SRS-22, the short form scale shows better targeting of the participants' population. RA shows that SRS-22 has poor clinimetric properties; moreover, when used with AIS at first evaluation, SRS-22 is affected by a severe ceiling effect. SRS-7, an SRS-22 7-item short form questionnaire, provides an HRQL interval measure better tailored to these participants. PMID:24521663

    Previous biochemical studies on cartilage tissue from a proband with Type II achondrogenesis-hypochondrogenesis (Godfrey, M., and Hollister, D. W. (1988) Am. J. Hum. Genet. 43, 904-913) indicated heterozygosity for a structural abnormality in the triple helical domain of pro-alpha 1 (II) collagen. Here we demonstrate that the mutation in the type II procollagen gene is a single base change that converts the codon for glycine (GGC) at amino acid 943 of the alpha 1 (II) chain to a codon for serine (AGC). The substitution disrupts the invariant Gly-X-Y structural motif necessary for perfect triple helix formation and leads to extensive overmodification, intracellular retention, and reduced secretion of type II collagen. These findings confirm the proposal that new dominant mutations in the type II procollagen gene may account for some cases of Type II achondrogenesis-hypochondrogenesis. Since recent studies (Lee, B., Vissing, H., Ramirez, F., Rogers, D., and Rimoin, D. (1989) Science 244, 978-980) have identified a dominantly inherited type II procollagen gene deletion in a non-lethal form of skeletal dysplasia, namely spondyloepiphyseal dysplasia, the data more generally demonstrate that different type II procollagen gene mutations eventuate in a wide and diverse spectrum of clinical phenotypes.

    Background The Composite International Diagnostic Interview – Short Form consists of short form scales for evaluating psychiatric disorders. Also for this version training of the interviewer is required. Moreover, the confidentiality could be not adequately protected. This study focuses on the preliminary validation of a brief self-completed questionnaire which originates from the CIDI-SF. Sampling and Methods A preliminary version was assessed for content and face validity. An intermediate version was evaluated for test-retest reliability. The final version of the questionnaire was evaluated for factor exploratory analysis, and internal consistency. Results After the modifications by the focus groups, the questionnaire included 29 initial probe questions and 56 secondary questions. The test retest reliability weighted Kappas were acceptable to excellent for the vast majority of questions. Factor analysis revealed six factors explaining 53.6% of total variance. Cronbach's alpha was 0.89 for the questionnaire and 0.89, 0.67, 0.71, 0.71, 0.49, and 0.67, for the six factors respectively. Conclusion The questionnaire has satisfactory reliability, and internal consistency, and might be efficient for using in community research and clinical practice. In the future, the questionnaire could be further validated (i.e., concurrent validity, discriminant validity). PMID:18402667

The discharge was created by a high-power (90 kW) pulsed radiation of a 37.5-GHz gyrotron. The normalized emittance of generated ion beams of 100 mA current was (1.2–1.3) π mm mrad (70% of ions in the beams). Comparing these results with those obtained using a cusp magnetic trap, it was concluded that the structure of the trap magnetic field lines does not exert a decisive influence on the emittance of ion beams in the gas-dynamic ECR source of MCI.

    Background: Perineal pain is a major morbidity in the first few days after delivery. This study aimed to investigate the effect of dry cupping therapy and acupressure at BL23 point on the intensity of postpartum perineal pain based on the short-form of McGill pain questionnaire (SMPQ). Methods: The present clinical trial was conducted on 150 subjects in 3 groups of 50 cases. After at least 4–8 hr of delivery, cupping therapy was performed for 15–20 min up to 3 times a week (once a day) and acupressure was performed for 15–20 min based on clockwise model. The short-form of McGill pain questionnaire was completed both before and after the intervention. The SPSS statistical software was used to analyze the data using repeated measures ANOVA. Besides, p<0.05 was considered statistically significant. Results: In the cupping therapy group, mean of the perineal pain intensity reduced from 37.5±6.8 before the intervention to 11.1±6.1, 6.9±4.7, and 3.8±3.6 immediately, 24 hr, and 2 weeks after the intervention, respectively. The results of study showed that the differences between the intervention and control groups were statistically significant (p<0.01). Mean difference of the perineal pain intensity in the acupressure group reached from 35.6±8.1 before the intervention to 10.4±5.5 two weeks after the intervention, so the variation between intervention and control groups was statistically significant. Conclusion: The study findings showed that cupping therapy and acupressure reduced perineal pain. Therefore, they may be considered as effective treatments for reducing pain intensity of allowing delivery. PMID:26962482

    Background The mortality prediction represents a key factor in the managing of elderly hospitalized patients. Since in older subjects mortality results from a combination of biological, functional, nutritional, psychological and environmental factors, a Multidimensional Prognostic Index (MPI) that predict short- and long-term mortality based on a standardized comprehensive geriatric assessment (CGA) has recently been developed and validated. Objective This study compares the accuracy in predicting the mortality of the MPI with a modified version of the MPI (m-MPI) that included the Mini Nutritional Assessment-Short Form (MNA-SF) instead of the standard MNA. Design This prospective study with a one-year follow-up included 4088 hospitalized patients aged 65 years and older. A standardized CGA that included information on functional (Activities of Daily Living, ADL and Instrumental-ADL), cognitive (Short Portable Mental Status Questionnaire), risk of pressure sore (Exton-Smith Scale), comorbidities (CIRS Index), medications, living status and nutritional status (MNA and MNA-SF) was used to calculate the MPI using a previously validated algorithm. Results Higher MPI values were significantly associated with higher mortality rates with a close agreement between the estimated and the observed mortality both after 1-month (MPI1=2.8% versus m-MPI1=2.8%, p=0.946; MPI2=8.9% versus m-MPI2=9%, p=0.904; MPI3=21.9% versus m-MPI3=21.9, p=0.978) and 1-year of follow-up (MPI1=10.8% versus m-MPI1=10.5%, p=0.686; MPI2=27.3% versus m-MPI2=28%, p=0.495; MPI3=52.8% versus m-MPI3=52.7%, p=0.945). The estimated areas under the receiver operating characteristics (ROC) curves suggested a clinically negligible difference between the two indices. Conclusion The m-MPI is as sensitive as the MPI in stratifying hospitalized elderly patients into groups at varying risk of short- and long-term mortality, but with fewer items. PMID:21369662

    STUDY OBJECTIVE: To examine the short form 36 (SF-36) health status measure when used to assess older people's views of the outcome of community based health care. DESIGN: Completion of a structured questionnaire, before and after intervention alongside in-depth interviews with a subsample of the interviewees. SETTING: Community based continence and mental health services in two health authorities in the North West Health Region. PATIENTS: Forty seven older people newly referred to mental health services or continence services between December 1992 and April 1993 participated. MAIN RESULTS: The SF-36 showed minimal change over time for both patient groups. The more detailed in-depth interviews showed that people experienced positive changes and derived value from contact with services in a number of important ways. For many reasons these benefits were not reflected in their SF-36 scores. CONCLUSIONS: The SF-36 is not likely to be the "measure of choice" for this type of evaluation, particularly where it involves older patient groups who have high levels of comorbidity. The content of the SF-36 and its lack of detail for individual assessment of change means it masks rather than illuminates patients' views of outcome. PMID:8762362

    Objective To describe the development and psychometric properties of the Spinal Cord Injury – Quality of Life (SCI-QOL) Bladder Management Difficulties and Bowel Management Difficulties item banks and Bladder Complications scale. Design Using a mixed-methods design, a pool of items assessing bladder and bowel-related concerns were developed using focus groups with individuals with spinal cord injury (SCI) and SCI clinicians, cognitive interviews, and item response theory (IRT) analytic approaches, including tests of model fit and differential item functioning. Setting Thirty-eight bladder items and 52 bowel items were tested at the University of Michigan, Kessler Foundation Research Center, the Rehabilitation Institute of Chicago, the University of Washington, Craig Hospital, and the James J. Peters VA Medical Center, Bronx, NY. Participants Seven hundred fifty-seven adults with traumatic SCI. Results The final item banks demonstrated unidimensionality (Bladder Management Difficulties CFI = 0.965; RMSEA = 0.093; Bowel Management Difficulties CFI = 0.955; RMSEA = 0.078) and acceptable fit to a graded response IRT model. The final calibrated Bladder Management Difficulties bank includes 15 items, and the final Bowel Management Difficulties item bank consists of 26 items. Additionally, 5 items related to urinary tract infections (UTI) did not fit with the larger Bladder Management Difficulties item bank but performed relatively well independently (CFI = 0.992, RMSEA = 0.050) and were thus retained as a separate scale. Conclusion The SCI-QOL Bladder Management Difficulties and Bowel Management Difficulties item banks are psychometrically robust and are available as computer adaptive tests or short forms. The SCI-QOL Bladder Complications scale is a brief, fixed-length outcomes instrument for individuals with a UTI. PMID:26010964

    Food security is a newly recommended outcome measure for the Older Americans Act Nutrition Program (OAANP); however, it is unknown how best to evaluate the need for this program and assess its impact on a large scale. Therefore, we measured food security in all new OAANP participants and waitlisted applicants in Georgia between July and early November, 2008 (n = 4731) with the self-administered mail survey method used in the ongoing Georgia Performance Outcomes Measures project. We used a modified 6-item U.S. Household Food Security Survey Module (HFSSM) with a 30-d reference period and 2 reminder postcards. Approximately 33% of those identified completed the survey (n = 1594, mean age 74.6 ± 9.5 y, 68.6% female, 30.6% black). Most of the respondents (91%) completed all 6 food security questions, whereas 26 did not respond to any question. Infit and outfit statistics for each of the 6 questions were within an acceptable range. Psychometric properties observed in our food security data were generally similar to those in the nationally representative survey conducted by the Census Bureau and suggest that our food security statistics may be meaningfully compared with national food security statistics published by the USDA. Our findings suggest that food security can be reasonably measured by a short form of HFSSM in older adults requesting OAANP. Such methodology also can be used to estimate the extent of food insecurity and help guide program and policy decisions to meet the nutrition assistance needs of vulnerable older adults.

    Objective To develop an item response theory (IRT)-calibrated spinal cord injury (SCI)-specific Positive Affect and Well-being (PAWB) item bank with flexible options for administration. Design Qualitative feedback from patient and provider focus groups was used to expand on the Neurological Disorders and Quality of Life (Neuro-QOL) positive affect & well-being item bank for use in SCI. New items were created and revised based on expert review and patient feedback and were then field tested. Analyses included confirmatory factor analysis, graded response IRT modeling and evaluation of differential item functioning (DIF). Setting We tested a 32-item pool at several rehabilitation centers across the United States, including the University of Michigan, Kessler Foundation, Rehabilitation Institute of Chicago, the University of Washington, Craig Hospital and the James J. Peters/Bronx Department of Veterans Affairs hospital. Participants A total of 717 individuals with SCI answered the PAWB questions. Results A unidimensional model was observed (Confirmatory Fit Index = 0.947; Root Mean Square Error of Approximation = 0.094) and measurement precision was good (reliability in theta of –2.9 to 1.2 is roughly equivalent to classical reliability of 0.95 or above). Twelve items were flagged for DIF, however, after examination of effect sizes, the DIF was determined to be negligible and would have little practical impact on score estimates. The final calibrated item bank resulted in 28 retained items Conclusions This study indicates that the Spinal Cord Injury – Quality of Life PAWB bank represents a psychometrically robust measurement tool. Short form items are also suggested and a computer adaptive test is available. PMID:26010970

    2014-01-01

    Context: It is agreed that it is important to anatomically reproduce the proximal humeral anatomy when performing a prosthetic shoulder replacement. This can be difficult with a long stemmed prosthesis, in particular if there is little relationship of the metaphysis to the humeral shaft. The ‘short stem’ prosthesis can deal with this problem. Aims: A prospective study assessed the results of total shoulder arthroplasty using a short stem humeral prosthesis, a ceramic humeral head, and a pegged cemented polyethylene glenoid. Materials and methods: Patients with primary shoulder osteoarthritis were recruited into this prospective trial and pre-operatively had the ASES, Constant, SPADI, and DASH scores recorded. The patients were clinically reviewed at the two weeks, eight weeks, one year, and two year mark with completion of a data form. Radiological evaluation was at the eight week, one year and two year follow-up. At the one and two year follow-up the satisfaction rating, the range of passive and active motion, Constant, ASES, SPADI, DASH and pain results were recorded and analysed with SPPS 20. Results: During the study period 97 short stem, ceramic head total shoulder replacements were carried out. At the time of follow-up 12 were two years from operation and 38 one year from operation. Active elevation was overall mean 160 degrees. Constant scores were 76 at 1 year, and 86 at 2 years, ASES 88 and 93, and satisfaction 96% and 98% respectively at one and 2 year follow up. There were no problems during insertion of the humeral prosthesis, or any radiolucent lines or movement of the prosthesis on later radiographs. Conclusion: The short stem prosthesis had no complications, and on follow up radiographs good bone fixation. These fairly short term clinical results were overall good. PMID:25258497

    Circular dichroism (CD) and Raman scattering were applied to the aqueous solution of minimalist LK peptides constructed with successive KL repeats leading to the following generic primary sequence: (KL)nK. Three peptides of this family, a 3-mer (n=1), a 9-mer (n=4), and a 15-mer (n=7), are analyzed in this report. Raman spectra of the 3-mer (KLK, a random chain) and its labile-hydrogen deuterated species yield a set of interesting information for analyzing longer peptides of this series. Although the CD spectrum of the 9-mer (KLKLKLKLK) reveals a signal traditionally assigned to a random structure, the corresponding Raman spectrum allows finding a mixture of conformations in solution, adopting predominantly beta-type structures. This fact proves the utility of Raman spectroscopy to eliminate eventual ambiguity concerning conformational assignments in peptides based only on the use of CD technique. Finally, the 15-mer (KLKLKLKLKLKLKLK) gives rise to CD and Raman spectra clearly assignable to a beta-type structure. On the basis of all the observed results on the 15-mer, we can confirm that this peptide may exist as isolated beta-strands at low concentration (sub-micromolar), flat-oriented at the air/water interface, whereas at high concentrations (millimolar), non-H-bonded immersible aggregates might be formed. A hypothetical model for these beta-strand aggregates could be proposed as stabilized by an interior hydrophobic core and a hydrophilic external face, formed by leucine and lysine side chains, respectively.

    The problem of form classification is to assign a single-page form image to one of a set of predefined form types or classes. We classify the form images using low level pixel density information from the binary images of the documents. In this paper, we solve the form classification problem with a classifier based on the k-means algorithm, supported by adaptive boosting. Our classification method is tested on the NIST scanned tax forms data bases (special forms databases 2 and 6) which include machine-typed and handwritten documents. Our method improves the performance over published results on the same databases, while still using a simple set of image features.

  2. Towards short wavelengths FELs workshop

    Ben-Zvi, I.; Winick, H.

    1993-12-01

    This workshop was caged because of the growing perception in the FEL source community that recent advances have made it possible to extend FEL operation to wavelengths about two orders of magnitude shorter than the 240 nm that has been achieved to date. In addition short wavelength FELs offer the possibilities of extremely high peak power (several gigawatts) and very short pulses (of the order of 100 fs). Several groups in the USA are developing plans for such short wavelength FEL facilities. However, reviewers of these plans have pointed out that it would be highly desirable to first carry out proof-of-principle experiments at longer wavelengths to increase confidence that the shorter wavelength devices will indeed perform as calculated. The need for such experiments has now been broadly accepted by the FEL community. Such experiments were the main focus of this workshop as described in the following objectives distributed to attendees: (1) Define measurements needed to gain confidence that short wavelength FELs will perform as calculated. (2) List possible hardware that could be used to carry out these measurements in the near term. (3) Define a prioritized FEL physics experimental program and suggested timetable. (4) Form collaborative teams to carry out this program.

    The aim of the study was to investigate the psychometric properties of a Short Form of the Mini-Mental State Examination (SMMSE) for the screening of dementia in older primary care patients. Data were obtained from a large longitudinal cohort study of initially nondemented individuals recruited via primary care chart registries and followed at 18-month intervals. Item and scale parameters for MMSE and SMMSE scores were analyzed and cross-validated for 2 follow-up assessments (n1 = 2,657 and n2 = 2,274). Binary logistic regression and receiver-operating-characteristic (ROC) curve analyses were conducted in order to assess diagnostic accuracy parameters for MMSE and SMMSE scores. Cross-sectional differentiation between dementia-free and dementia patients yielded moderate to good results for MMSE and SMMSE scores. With regard to most diagnostic accuracy parameters, SMMSE scores did not outperform the MMSE scores. The current study provides first evidence regarding the psychometric properties of the SMMSE score in a sample of older primary care patients. However, our findings do not confirm previous findings that the SMMSE is a more accurate screening instrument for dementia than the original MMSE. Further studies are needed in order to assess and to develop short, reliable and valid instruments for routine cognitive screening in clinical practice and primary care settings. PMID:25822830

    A bipolar pulse forming transmission line module for linear induction accelerators having first, second, third, fourth, and fifth planar conductors which form an interleaved stack with dielectric layers between the conductors. Each conductor has a first end, and a second end adjacent an acceleration axis. The first and second planar conductors are connected to each other at the second ends, the fourth and fifth planar conductors are connected to each other at the second ends, and the first and fifth planar conductors are connected to each other at the first ends via a shorting plate adjacent the first ends. The third planar conductor is electrically connectable to a high voltage source, and an internal switch functions to short a high voltage from the first end of the third planar conductor to the first end of the fourth planar conductor to produce a bipolar pulse at the acceleration axis with a zero net time integral. Improved access to the switch is enabled by an aperture through the shorting plate and the proximity of the aperture to the switch.

    Shunt and short circuit are antonyms. In French, the term shunt has been adopted to denote the alternative pathway of blood flow. However, in French, as well as in Spanish, the word short circuit (court-circuit and cortocircuito) is synonymous with shunt, giving rise to a linguistic and scientific inconsistency. Scientific because shunt and short circuit made reference to a phenomenon that occurs in the field of the physics. Because shunt and short circuit are antonyms, it is necessary to clarify that shunt is an alternative pathway of flow from a net of high resistance to a net of low resistance, maintaining the stream. Short circuit is the interruption of the flow, because a high resistance impeaches the flood. This concept is applied to electrical and cardiovascular physiology, as well as to the metabolic pathways. PMID:17257492

  11. Short crack growth behavior

    Sadananda, K.; Vasudevan, A.K.

    1997-12-01

    The authors have re-evaluated short crack growth behavior using concepts developed recently, and they show that these concepts provide a unified framework that can explain both short and long crack growth behavior without resorting to the crack closure effect. They consider that the behavior of long cracks, including the effects of load ratio, R, is fundamental. they had shown previously that, since fatigue is at least a two-parameter problem in that at least two load parameters are required for an unambiguous description, there are two critical driving forces required simultaneously for fatigue cracks to grow. In extending this analysis to the growth of short cracks, they reject the current notion of the lack of similitude for short cracks and express the similitude as a fundamental postulate that, for a given crack growth mechanism, equal crack tip driving forces result in equal crack growth rates. Short crack growth behavior confirms the concept that two parameters are required to define fatigue; consequently, for fatigue cracks to grow, two thresholds need to be satisfied simultaneously. The authors present examples from the literature to illustrate the concepts discussed.

  12. Tidal Forms

    2003-04-01

    We give an overview of some recent investigations on the mechanics of the processes whereby forms develop in tidal environments. The viewpoint taken here is mechanistic. Some of the questions which deserve an answer may be summarised as follows: i) do tidal channels tend to some altimetric long term equilibrium? ii) why are they typically convergent and weakly meandering? iii) how is such equilibrium affected by the hydrodynamics and morphodynamics of tidal inlets? iv) what is the hydrodynamic and morphodynamic role played by tidal flats adjacent to the channels? Some of the above questions have received a considerable attention in the last few years. Schuttelaars and de Swart (1996), Lanzoni and Seminara (2002) and, more recently, Bolla Pittaluga (2003) have investigated the first problem. In particular, the latter two contributions have shown that a straight tidal channel connected to a tidal sea at one end and closed at the other end tends to reach a long term equilibrium profile, which is slightly concave seaward and convex landward where a beach forms. The equilibrium profile is strongly sensitive to the harmonic content of the tidal forcing as well as to the value of sediment concentration established by the coastal hydrodynamics in the far field of the inlet region. Less important are the effect of channel convergence and the role of settling lag in the transport of suspended load. Insufficient attention has been devoted to the understanding of what mechanisms control channel convergence and meandering, though some similarities and differences between tidal and fluvial channels have emerged from some recent works. In particular, free bars form in tidal channels due to an instability mechanism essentially similar to that occurring under steady conditions though the oscillatory character of the flow field makes the bar pattern non migrating (Seminara and Tubino, 2001). Similarly, forced bars in curved tidal channels are driven by the development of

    >A short pulse stretching circuit capable of stretching a short puise to enable it to be displayed on a relatively slow sweeping oscilloscope is described. Moreover, the duration of the pulse is increased by charging a capacitor through a diode and thereafter discharging the capacitor at such time as is desired. In the circuit the trigger pulse alone passes through a delay line, whereas the main signal passes through the diode only, and results in over-all circuit losses which are proportional to the low losses of the diode only.

    Research was conducted concerning the relation of short-perihelion meteor streams with comets and asteroids. But the origin of meteor streams with small perihelion distance (of the Arietid and Geminid types) has always represented a special problem for obvious reasons. Over four hundred meteor and fireball streams (by optical and TV-observations) contained 20 streams of perihelion distance q ≤ 0.26 AU. The research shows that 8 of 20 streams displayed a relation with small bodies. No relation was found either with comets or asteroids for the remaining 12 streams. Short-period streams may be formed on quasiparabolic comet orbits with small q in the perihelion area as well. In particular, SOHO comets may be a rich source both of small and large meteor bodies, forming short-perihelion meteor streams among others.

    A ceramic short circuit resistant capacitor that is bendable and/or shapeable to provide a multiple layer capacitor that is extremely compact and amenable to desirable geometries. The capacitor that exhibits a benign failure mode in which a multitude of discrete failure events result in a gradual loss of capacitance. Each event is a localized event in which localized heating causes an adjacent portion of one or both of the electrodes to vaporize, physically cleaning away electrode material from the failure site. A first metal electrode, a second metal electrode, and a ceramic dielectric layer between the electrodes are thin enough to be formed in a serpentine-arrangement with gaps between the first electrode and the second electrode that allow venting of vaporized electrode material in the event of a benign failure.

    The nucleons in a nucleus can form short-range correlated pairs. A recent Jefferson Lab electron scattering experiment, where a proton was knocked-out of the nucleus with high momentum transfer and high missing momentum, has shown that in {sup 12}C the neutron-proton pairs are nearly twenty times as prevalent as proton-proton pairs and, by inference, neutron-neutron pairs. This difference between the types of pairs has been shown to be due to the short-range tensor part of the nucleon-nucleon interaction.

    Short term plasticity is a highly abundant form of rapid, activity-dependent modulation of synaptic efficacy. A shared set of mechanisms can cause both depression and enhancement of the postsynaptic response at different synapses, with important consequences for information processing. Mathematical models have been extensively used to study the mechanisms and roles of short term plasticity. This review provides an overview of existing models and their biological basis, and of their main properties. Special attention will be given to slow processes such as calcium channel inactivation and the effect of activation of presynaptic autoreceptors. PMID:23626536

  8. Scottish Short Stone Rows

    NASA Astrophysics Data System (ADS)

    Ruggles, Clive L. N.

    Short stone rows received a good deal of attention during the 1980s and 1990s, at a time when archaeoastronomy in prehistoric Britain and Ireland was moving beyond reassessments of Alexander Thom's "megalithic observatories" by identifying coherent groups of similar monuments with clear orientation trends. Many such rows are found in western Scotland, with the main concentration in Argyll and the island of Mull. Systematic analyses of their orientations produced credible evidence of an awareness of the 18.6-year lunar node cycle, within a "primary-secondary" pattern whereby isolated rows were oriented close to moonrise or moonset at the southern major standstill limit, while others oriented in this way were accompanied by a second row oriented in a declination range that could be interpreted either as lunar or solar. A detailed investigation of the landscape situation of the sites in northern Mull, accompanied by excavations at two of the sites, suggested that they were deliberately placed in locations where critical moonsets would be seen against prominent distant landscape features, but where the distant horizon in most or all other directions was hidden from view. A lack of independent archaeological evidence may help to explain why archaeoastronomical investigations at short stone rows have never progressed beyond "data-driven" studies of orientations and landscape situation. Nonetheless, the work that was done at these sites raised important general methodological issues, and pioneered techniques, that remain relevant across archaeoastronomy today.

    The maintenance of information in auditory short-term memory (ASTM) is accompanied by a sustained anterior negativity (SAN) in the event-related potential measured during the retention interval of simple auditory memory tasks. Previous work on ASTM showed that the amplitude of the SAN increased in negativity as the number of maintained items increases. The aim of the current study was to measure the SAN and observe its behavior beyond the point of saturation of auditory short-term memory. We used atonal pure tones in sequences of 2, 4, 6, or 8t. Our results showed that the amplitude of SAN increased in negativity from 2 to 4 items and then levelled off from 4 to 8 items. Behavioral results suggested that the average span in the task was slightly below 3, which was consistent with the observed plateau in the electrophysiological results. Furthermore, the amplitude of the SAN predicted individual differences in auditory memory capacity. The results support the hypothesis that the SAN is an electrophysiological index of brain activity specifically related to the maintenance of auditory information in ASTM. PMID:25446005

  13. Short-Lived Climate Pollution

    NASA Astrophysics Data System (ADS)

    Pierrehumbert, R. T.

    2014-05-01

    Although carbon dioxide emissions are by far the most important mediator of anthropogenic climate disruption, a number of shorter-lived substances with atmospheric lifetimes of under a few decades also contribute significantly to the radiative forcing that drives climate change. In recent years, the argument that early and aggressive mitigation of the emission of these substances or their precursors forms an essential part of any climate protection strategy has gained a considerable following. There is often an implication that such control can in some way make up for the current inaction on carbon dioxide emissions. The prime targets for mitigation, known collectively as short-lived climate pollution (SLCP), are methane, hydrofluo-rocarbons, black carbon, and ozone. A re-examination of the issues shows that the benefits of early SLCP mitigation have been greatly exaggerated, largely because of inadequacies in the methodologies used to compare the climate effects of short-lived substances with those of CO2, which causes nearly irreversible climate change persisting millennia after emissions cease. Eventual mitigation of SLCP can make a useful contribution to climate protection, but there is little to be gained by implementing SLCP mitigation before stringent carbon dioxide controls are in place and have caused annual emissions to approach zero. Any earlier implementation of SLCP mitigation that substitutes to any significant extent for carbon dioxide mitigation will lead to a climate irreversibly warmer than will a strategy with delayed SLCP mitigation. SLCP mitigation does not buy time for implementation of stringent controls on CO2 emissions.

    The Grebe syndrome is a nonlethal form of severe short-limbed dwarfism which was previously called "achondrogenesis-Brazilian or Grebe type". We have studied three patients with severe short-limbed dwarfism originally considered to have this syndrome. On re-evaluation of their clinical and radiographic features, only one of them had the typical features of the Grebe chondrodysplasia, whereas the other two appear to have clearly distinct, previously unreported skeletal dysplasias. These patients illustrate the heterogeneity that exists among the nonlethal forms of severe short-limbed dwarfism. PMID:925797

    It is submitted that the thermal action of short-wave therapy does not account for the therapeutic results obtained. The theory is put forward that many of the results obtained can be better explained by the disruptive and dispersive action of the impact of the electromagnetic vibrations. An analogy, indicating such disruptive effects at high frequency, is drawn from the molecular vibrations—transmitted through transformer oil, and excited by the application of high frequency currents to the layers of quartz in the piezo-electric oscillator of quartz. It is submitted that these disruptive and dispersive effects will be greatest where the conductivity of the tissues is low, such as in bones and fat, and it is shown that it is in these regions that the therapeutic action of these currents is most obvious. It is also pointed out that, if effects, comparable to those obtained in the subcutaneous area, are obtained in the deeper tissues and organs, the application of deep-wave therapy would be attended by serious risk.

    Over the years, most of the mental disorders that are dealt with in everyday clinical practice have changed not only their names but also their conceptualisation. Furthermore, as some disorders disappear or are forgotten, others come into being. Seen from a historical perspective and unlike many of the diseases included within classical medicine, it can be stated that one of the basic characteristics of mental disorders is their short-lived presence in the scientific literature. In this study we analyse the causes underlying the transitory nature of mental disorders. The disappearance of a disorder or the modification of how it is conceptualised may be linked to several different motives. Sometimes they may be due to an evolution of the construct, as a result of new findings. On other occasions the disorder falls into disuse owing to the weakness of the theoretical construct or the clinical research upholding it. Lastly, because the Diagnostic and Statistical Manual of Mental Disorders and the International Classification of Diseases require updates that incorporate new contributions and correct faults in the current model, they give rise to new denominations and definitions in mental disorders. This article analyses these three situations and offers an illustrative example in each case. PMID:22374762

    Objective: To determine predictors of survival and of weaning off parenteral nutrition (PN) in pediatric short bowel syndrome (SBS) patients. Summary Background Data: Pediatric SBS carries extensive morbidity and high mortality, but factors believed to predict survival or weaning from PN have been based on limited studies. This study reviews outcomes of a large number of SBS infants and identifies predictors of success. Methods: Multivariate Cox proportional hazards analysis was conducted on 80 pediatric SBS patients. Primary outcome was survival; secondary outcome was ability to wean off PN. Nonsignificant covariates were eliminated. P < 0.05 was considered significant. Results: Over a mean of 5.1 years of follow-up, survival was 58 of 80 (72.5%) and 51 weaned off PN (63.8%). Cholestasis (conjugated bilirubin ≥2.5 mg/dL) was the strongest predictor of mortality (relative risk [RR] 22.7, P = 0.005). Although absolute small bowel length was only slightly predictive, percentage of normal bowel length (for a given infant's gestational age) was strongly predictive of mortality (if <10% of normal length, RR of death was 5.7, P = 0.003) and of weaning PN (if ≥10% of normal, RR of weaning PN was 11.8, P = 0.001). Presence of the ileocecal valve (ICV) also strongly predicted weaning PN (RR 3.9, P < 0.0005); however, ICV was not predictive of survival. Conclusions: Cholestasis and age-adjusted small bowel length are the major predictors of mortality in pediatric SBS. Age-adjusted small bowel length and ICV are the major predictors of weaning from PN. These data permit better prediction of outcomes of pediatric SBS, which may help to direct future management of these challenging patients. PMID:16135926

    Water electrolysis in a microsystem is observed and analyzed on a short-time scale of ∼10 μs. The very unusual properties of the process are stressed. An extremely high current density is observed because the process is not limited by the diffusion of electroactive species. The high current is accompanied by a high relative supersaturation, S > 1000, that results in homogeneous nucleation of bubbles. On the short-time scale only nanobubbles can be formed. These nanobubbles densely cover the electrodes and aggregate at a later time to microbubbles. The effect is significantly intensified with a small increase of temperature. Application of alternating polarity voltage pulses produces bubbles containing a mixture of hydrogen and oxygen. Spontaneous reaction between gases is observed for stoichiometric bubbles with sizes smaller than ∼150 nm. Such bubbles disintegrate violently affecting the surfaces of the electrodes.

    Introduction Skin cancer is one of the most common secondary neoplasms among childhood cancer survivors. However, little evidence exists for effective interventions to promote sun safety behaviors within this population. Methods This small-scale randomized controlled trial examined the efficacy of the Survivor Health and Resilience Education (SHARE) Program intervention, a multiple health behavior change intervention designed to increase sun safety practices among adolescent survivors of childhood cancer. Adolescent survivors of childhood cancer (11-21 years) were randomly allocated to a group-based behavioral intervention (n = 38) or wait-list control (n = 37). Self-reported sun safety behaviors were assessed using a valid, 8-item scale at baseline and 1-month post-intervention. Results Controlling for baseline sun safety, gender, and seasonal influences, intervention participants reported significantly more sun safety practices (e.g., using sunscreen, reapplying sunscreen regularly) at 1-month post-intervention than control participants (B = 2.64, 95% CI = 1.02, 4.27, p = 0.002). Conclusions The results suggest that SHARE was efficacious in producing improvements in short-term self-reported sun safety practices among adolescent survivors of childhood cancer. Future research is needed to build upon this work by incorporating objective measures of sun safety behaviors and examining intervention durability. Implications for Cancer Survivors Behavioral interventions addressing lifestyle factors, including sun safety behaviors, among adolescent survivors of childhood cancer should be integrated into long-term care to reduce the risk for secondary malignancies and diseases.

    Background/Aims Short stature is a common reason for presentation to pediatric endocrinology clinics. However, for most patients, no cause for the short stature can be identified. As genetics plays a strong role in height, we sought to identify known and novel genetic causes of short stature. Methods We recruited 14 children with severe short stature of unknown etiology. We conducted whole exome sequencing of the patients and their family members. We used an analysis pipeline to identify rare nonsynonymous genetic variants that cause the short stature. Results We identified a genetic cause of short stature in 5 of the 14 patients. This included cases of Floating Harbor syndrome, Kenny-Caffey syndrome, the progeroid form of Ehlers-Danlos syndrome, as well as two cases of the 3-M syndrome. For remaining patients, we have generated lists of candidate variants. Conclusions Whole exome sequencing can help identify genetic causes of short stature in the context of defined genetic syndromes, but may be less effective in identifying novel genetic causes of short stature in individual families. Utilized in the clinic, whole exome sequencing can provide clinically relevant diagnoses for these patients. Rare syndromic causes of short stature may be under-recognized and under-diagnosed in pediatric endocrinology clinics. PMID:24970356

    High-power, short-pulse lasers in the picosecond and subpicosecond range are utilized in an increasing number of technologies, including materials processing and diagnostics, micro-electronics and devices, and medicine. In these applications, the short-pulse radiation interacts with a wide range of media encompassing disordered materials and liquids. Examples of disordered materials include porous media, polymers, organic tissues, and amorphous forms of silicon, silicon nitride, and silicon dioxide. In order to accurately model, efficiently control, and optimize short-pulse, laser-material interactions, a thorough understanding of the energy transport mechanisms is necessary. Thus, fractals and percolation theory are used to analyze the anomalous diffusion regime in random media. In liquids, the thermal aspects of saturable and multiphoton absorption are examined. Finally, a novel application of short-pulse laser radiation to reduce surface adhesion forces in microstructures through short-pulse laser-induced water desorption is presented.

    Context: Genetics plays a major role in determining an individual's height. Although there are many monogenic disorders that lead to perturbations in growth and result in short stature, there is still no consensus as to the role that genetic diagnostics should play in the evaluation of a child with short stature. Evidence Acquisition: A search of PubMed was performed, focusing on the genetic diagnosis of short stature as well as on specific diagnostic subgroups included in this article. Consensus guidelines were reviewed. Evidence Synthesis: There are a multitude of rare genetic causes of severe short stature. There is no high-quality evidence to define the optimal approach to the genetic evaluation of short stature. We review genetic etiologies of a number of diagnostic subgroups and propose an algorithm for genetic testing based on these subgroups. Conclusion: Advances in genomic technologies are revolutionizing the diagnostic approach to short stature. Endocrinologists must become facile with the use of genetic testing in order to identify the various monogenic disorders that present with short stature. PMID:24915122

    The authors study the short-time dynamics of helix-forming polypeptide chains using an all-atom representation of the molecules and an implicit solvation model to approximate the interaction with the surrounding solvent. The results confirm earlier observations that the helix-coil transition in proteins can be described by a set of critical exponents. The high statistics of the simulations allows the authors to determine the exponent values with increased precision and support universality of the helix-coil transition in homopolymers and (helical) proteins.

    A computer code was developed to evaluate the space radiation environment encountered by geocentric satellites. The Short Orbital Flux Integration Program (SOFIP) is a compact routine of modular compositions, designed mostly with structured programming techniques in order to provide core and time economy and ease of use. The program in its simplest form produces for a given input trajectory a composite integral orbital spectrum of either protons or electrons. Additional features are available separately or in combination with the inclusion of the corresponding (optional) modules. The code is described in detail, and the function and usage of the various modules are explained. A program listing and sample outputs are attached.

    This document details the feasibility studies conducted for the Intentionally Short Range Communications (ISRC) project. The short-range limitation arises from the need for low probability of intercept (LPI), low probability of detection (LPD) communication links. The detection of an undecipherable transmission would still provide an enemy with information regarding transmitter location. The technologies being studied are ultraviolet (UV) lamps, UV lasers, infrared (IR) lasers, millimeter waves (MMW), and direct sequence spread spectrum.

  20. Dechirper wakefields for short bunches

    Bane, Karl; Stupakov, Gennady

    2016-06-01

    In previous work (Bane and Stupakov, 2015 [1]) general expressions, valid for arbitrary bunch lengths, were derived for the wakefields of corrugated structures with flat geometry, such as is used in the RadiaBeam/LCLS dechirper. However, the bunch at the end of linac-based X-ray FELs-like the LCLS-is extremely short, and for short bunches the wakes can be considerably simplified. In this work, we first derive analytical approximations to the short-range wakes. These are generalized wakes, in the sense that their validity is not limited to a small neighborhood of the symmetry axis, but rather extends to arbitrary transverse offsets of driving and test particles. The validity of these short-bunch wakes holds not only for the corrugated structure, but rather for any flat structure whose beam-cavity interaction can be described by a surface impedance. We use these wakes to obtain, for a short bunch passing through a dechirper: estimates of the energy loss as function of gap, the transverse kick as a function of beam offset, the slice energy spread increase, and the emittance growth. In the Appendix, a more accurate derivation-than that is found in Bane and Stupakov (2015) [1]-of the arbitrary bunch length wakes is performed; we find full agreement with the earlier results, provided the bunches are short compared to the dechirper gap, which is normally the regime of interest.

  1. Magnet Coil Shorted Turn Detector

    Dinkel, J.A.; Biggs, J.E.

    1994-03-01

    The Magnet Coil Shorted Turn Detector has been developed to facilitate the location of shorted turns in magnet coils. Finding these shorted turns is necessary to determine failure modes that are a necessary step in developing future production techniques. Up to this point, coils with shorted turns had the insulation burned off without the fault having been located. This disassembly process destroyed any chance of being able to find the fault. In order to maintain a flux balance in a coupled system such as a magnet coil, the current in a shorted turn must be opposed to the incident current. If the direction of the current in each conductor can be measured relative to the incident current, then the exact location of the short can be determined. In this device, an AC voltage is applied to the magnet under test. A small hand held B-dot pickup coil monitors the magnetic field produced by current in the individual magnet conductors. The relative phase of this pickup coil voltage is compared to a reference signal derived from the input current to detect a current reversal as the B-dot pickup coil is swept over the conductors of the coil under test. This technique however, is limited to only those conductors that are accessible to the hand held probe.

  7. Long Swarms and Short Swarms

    2011-12-01

    Many earthquake swarms at volcanoes last several months, then have a sharp uptick in rate in the hours before eruption. Examples include 2006 Augustine, 8.5 months then 10 hours; 1992 Spurr, 10 months then 4 hours; 1994 Rabaul, ~1 year then 27 hours; 2008 Kasatochi, 6 weeks then 2 days; and 2011 Puyuehue Cordon Caulle, 5 weeks then 2 days. For the well studied Augustine case, broadband data showed that very long period (VLP) energy accompanied 221 of 722 located earthquakes in the 10 hours before the first explosive eruption on 11 January 2006. This was revealed by low-pass filtering and the period of the VLP signal was 50 sec. The Augustine broadband stations were campaign instruments at distances of 2-3 km from the vent. No similar VLP energy has been found in events during the 8.5 month long swarm. Okmok volcano had a short swarm only lasting 5 hours prior to its 12 July 2008 eruption. Low-pass filtering of data from broadband station OKSO, 10 km from the vent, showed that 23 of 42 located events had VLP energy with a period of 30-40 sec. Events from Kasatochi volcano were scanned on station ATKA. Here the broadband station is much farther away at 88 km but the earthquakes in the short swarm 7 August 2008 were much larger with many M>3 events. The station suffered data gaps so only a few hours of data were scanned but numerous events were observed with VLP energy starting just after the P phase. Low-pass filtering showed VLP energy with a period of 10-12 sec. No VLP energy has been found in events of the preceding 6 week long swarm. These observations at three different volcanoes suggest that the short swarms represent a different process than the long swarms. The long swarms likely reflect pressure increases in the surrounding country rock caused by increasing magma pressure. The short swarms in contrast, appear to represent discrete pulses of magma injection at shallow depths. For all three volcanoes the earthquakes looked like typical volcano-tectonic (VT

    2006-01-10

    An ion source has an extraction system configured to produce ultra-short ion pulses, i.e. pulses with pulse width of about 1 .mu.s or less, and a neutron source based on the ion source produces correspondingly ultra-short neutron pulses. To form a neutron source, a neutron generating target is positioned to receive an accelerated extracted ion beam from the ion source. To produce the ultra-short ion or neutron pulses, the apertures in the extraction system of the ion source are suitably sized to prevent ion leakage, the electrodes are suitably spaced, and the extraction voltage is controlled. The ion beam current leaving the source is regulated by applying ultra-short voltage pulses of a suitable voltage on the extraction electrode.

  5. "Short, Hard Gamma-Ray Bursts - Mystery Solved?????"

    NASA Technical Reports Server (NTRS)

    Parsons, A.

    2006-01-01

    After over a decade of speculation about the nature of short-duration hard-spectrum gamma-ray bursts (GRBs), the recent detection of afterglow emission from a small number of short bursts has provided the first physical constraints on possible progenitor models. While the discovery of afterglow emission from long GRBs was a real breakthrough linking their origin to star forming galaxies, and hence the death of massive stars, the progenitors, energetics, and environments for short gamma-ray burst events remain elusive despite a few recent localizations. Thus far, the nature of the host galaxies measured indicates that short GRBs arise from an old (> 1 Gyr) stellar population, strengthening earlier suggestions and providing support for coalescing compact object binaries as the progenitors. On the other hand, some of the short burst afterglow observations cannot be easily explained in the coalescence scenario. These observations raise the possibility that short GRBs may have different or multiple progenitors systems. The study of the short-hard GRB afterglows has been made possible by the Swift Gamma-ray Burst Explorer, launched in November of 2004. Swift is equipped with a coded aperture gamma-ray telescope that can observe up to 2 steradians of the sky and can compute the position of a gamma-ray burst to within 2-3 arcmin in less than 10 seconds. The Swift spacecraft can slew on to this burst position without human intervention, allowing its on-board x ray and optical telescopes to study the afterglow within 2 minutes of the original GRB trigger. More Swift short burst detections and afterglow measurements are needed before we can declare that the mystery of short gamma-ray burst is solved.

  6. J-factors of short DNA molecules.

    PubMed

    Zoli, Marco

    2016-06-01

    The propensity of short DNA sequences to convert to the circular form is studied by a mesoscopic Hamiltonian method which incorporates both the bending of the molecule axis and the intrinsic twist of the DNA strands. The base pair fluctuations with respect to the helix diameter are treated as path trajectories in the imaginary time path integral formalism. The partition function for the sub-ensemble of closed molecules is computed by imposing chain end boundary conditions both on the radial fluctuations and on the angular degrees of freedom. The cyclization probability, the J-factor, proves to be highly sensitive to the stacking potential, mostly to its nonlinear parameters. We find that the J-factor generally decreases by reducing the sequence length (N) and, more significantly, below N = 100 base pairs. However, even for very small molecules, the J-factors remain sizeable in line with recent experimental indications. Large bending angles between adjacent base pairs and anharmonic stacking appear as the causes of the helix flexibility at short length scales. PMID:27276942

  7. Modelling microstructurally sensitive fatigue short crack growth

    NASA Astrophysics Data System (ADS)

    de Los Rios, E. R.; Xin, X. J.; Navarro, A.

    1994-10-01

    Microstructurally sensitive fatigue short crack growth can occur in many engineering components devoid of large defects. Continuum mechanics principles, including linear elastic fracture mechanics, used in damage tolerance design and life prediction methods are not applicable in these situations and therefore new concepts need to be developed to characterize this type of growth. A microstructurally sensitive model of fatigue crack growth is presented in which the effect of microstructure is dominant in the early stage of growth but plays a negligible role after the crack has gone through the transition from structure-sensitive to structure-insensitive growth. The effect of both microstructure and structure sensitive variables on the transition from short cracks to continuum mechanics and the conditions for crack instability leading to final failure are examined. The microstructural variables incorporated in the equations that describe the model are those controlling the extent and intensity of crack tip plasticity such as grain size, precipitation and dispersion hardening, strain hardening and mis-orientation between grains. It is expected that the concepts developed within the model will form the basis for the design of new crack-resistant materials.

    This short survey the reviews recent literature on brain connectivity studies. It encompasses all forms of static and dynamic connectivity whether anatomical, functional, or effective. The last decade has seen an ever increasing number of studies devoted to deduce functional or effective connectivity, mostly from functional neuroimaging experiments. Resting state conditions have become a dominant experimental paradigm, and a number of resting state networks, among them the prominent default mode network, have been identified. Graphical models represent a convenient vehicle to formalize experimental findings and to closely and quantitatively characterize the various networks identified. Underlying these abstract concepts are anatomical networks, the so-called connectome, which can be investigated by functional imaging techniques as well. Future studies have to bridge the gap between anatomical neuronal connections and related functional or effective connectivities. PMID:23097663

    New regularities for short-perihelion comets are found. Distant nodes of cometary orbits of Kreutz family are concentrated in a plane with ascending node 76 and inclination 267 at the distance from 2 up to 3 a.u. and in a very narrow interval of longitudes. There is a correlation dependence between q and cos I concerning the found plane (coefficient of correlation 0.41). Similar results are received regarding to cometary families of Meyer, Kracht and Marsden. Distant nodes of these comets are concentrated close three planes (their parameters are discussed in the article) and at distances 1.4; 0.5; 6 a.u. accordingly. It is concluded that these comet groups were formed as a result of collision of parent bodies with meteoric streams. One more group, consisting of 7 comets is identified. 5 comet pairs are selected among sungrazers.

    Based on the solution of the Boltzmann transport equation for a homogeneous base transistor [A.A. Grinberg and S. Luryi, Solid-St. Electron, 35, 1299 (1992)] a very instructive model of carrier transport in a short base transistor is developed. Essential to the above is a replacement of the Schottky boundary conditions. Using modified boundary conditions to the diffusion equation, the transport current density in a homogeneous base is predicted, to an accuracy within ±3%, regardless of the base width, covering the whole range from the diffusion controlled regime to the thermionic regime. Based on the modified boundary conditions a corrected Moll-Ross-Kroemer relation valid for a very short non-homogeneous base is derived. Correspondingly, an expression for the base transit time is derived.

  11. Optimal Short-Sighted Rules

    2012-01-01

    The aim of this paper is to assess the relevance of methodological transfers from behavioral ecology to experimental economics with respect to the elicitation of intertemporal preferences. More precisely our discussion will stem from the analysis of Stephens and Anderson’s (2001) seminal article. In their study with blue jays they document that foraging behavior typically implements short-sighted choice rules which are beneficial in the long run. Such long-term profitability of short-sighted behavior cannot be evidenced when using a self-control paradigm (one which contrasts in a binary way sooner smaller and later larger payoffs) but becomes apparent when ecological patch-paradigms (replicating economic situations in which the main trade-off consists in staying on a food patch or leaving for another patch) are implemented. We transfer this methodology in view of contrasting foraging strategies and self-control in human intertemporal choices. PMID:22973188

    Şıklar, Zeynep; Berberoğlu, Merih

    2014-01-01

    Short stature is one of the major components of many dysmorphic syndromes. Growth failure may be due to a wide variety of mechanisms, either related to the growth hormone (GH)/insulin-like growth factor axis or to underlying unknown pathologies. In this review, the relatively more frequently seen syndromes with short stature (Noonan syndrome, Prader-Willi syndrome, Silver-Russell syndrome and Aarskog-Scott syndrome) were discussed. These disorders are associated with a number of endocrinopathies, as well as with developmental, systemic and behavioral issues. At present, GH therapy is used in most syndromic disorders, although long-term studies evaluating this treatment are insufficient and some controversies exist with regard to GH dose, optimal age to begin therapy and adverse effects. Before starting GH treatment, patients with syndromic disorders should be evaluated extensively. PMID:24637303

    This paper is aimed at a combined theoretical and numerical study of the force-extension relation of a short DNA molecule stretched in an electrolyte. A theoretical formula based on a recent discrete wormlike chain (WLC) model of Kierfeld et al. (Eur Phys. J. E, Vol. 14, pp.17-34, 2004) and the classical OSF mean-field theory on electrostatic stiffening of a charged polymer is numerically verified by a set of Brownian dynamics simulations based on a generalized bead-rod (GBR) model incorporating long-ranged electrostatic interactions via the Debye-Hueckel potential (DH). The analysis indicates that the stretching of a short DNA can be well described as a WLC with a constant effective persistent length. This contrasts the behavior of long DNA chains that are known to exhibit variable persistent lengths depending on the ion concentration levels and force magnitudes. PMID:16711068

    There has recently been a substantial amount of research devoted to the development of short wavelength amplifiers and lasers. A number of experimental results have been published wherein the observation of significant gain has been claimed on transitions in the EUV and soft x-ray regimes. The present review is intended to discuss the main approaches to the creation of population inversions and laser media in the short wavelength regime, and hopefully aid workers in the field by helping to provide access to a growing literature. The approaches to pumping EUV and soft x-ray lasers are discussed according to inversion mechanism. The approaches may be divided into roughly seven categories, including collisional excitation pumping, recombination pumping, direct photoionization and photoexcitation pumping, metastable state storage plus optical pumping, charge exchange pumping, and finally, the extension of free electron laser techniques into the EUV and soft x-ray regimes. 250 references.

  15. The short-bowel syndrome.

    Patients with a short bowel have usually had a bowel resection for Crohn's disease. Two types of short-bowel patient can be distinguished: those with a jejunostomy and those with their jejunum anastomosed to a functioning colon. Both types of patient have problems with macronutrient absorption, although those with a colon experience fewer problems because some energy from unabsorbed carbohydrate is salvaged in the colon. Patients with a jejunostomy have problems with large stomal losses of water, sodium and magnesium, whereas those with a jejuno-colic anastomosis rarely have problems with water and electrolyte absorption. Patients with a jejunostomy 100-200 cm from the duodeno-jejunal flexure ('absorbers') usually absorb more from the diet than they pass through the stoma and therefore require oral electrolyte or nutrient supplements. Those with a residual jejunal length of less than 100 cm usually secrete more from the stoma than they take in orally ('secretors') and therefore require long-term parenteral fluid or nutrient supplements. A high output resulting from a jejunostomy is treated by reducing the oral intake of hypotonic fluid, administering a sipped glucose-saline solution and, often, by giving drugs that reduce intestinal motility (most effective in absorbers) or gastrointestinal secretions (most effective in secretors). Gallstones are common both in short-bowel patients with and in those without a colon (45%), and calcium oxalate renal stones occur in the former (25%). However, it is now possible to provide adequate nutrition and fluid supplements for most patients with a short bowel, and the prospects for the rehabilitation of such patients are good. PMID:7552632

  16. Short wind waves on the ocean: Wavenumber-frequency spectra

    NASA Astrophysics Data System (ADS)

    Plant, William J.

    2015-03-01

    Dominant surface waves on the ocean exhibit a dispersion relation that confines their energy to a curve in a wavenumber-frequency spectrum. Short wind waves on the ocean, on the other hand, are advected by these dominant waves so that they do not exhibit a well-defined dispersion relation over many realizations of the surface. Here we show that the short-wave analog to the dispersion relation is a distributed spectrum in the wavenumber-frequency plane that collapses to the standard dispersion relation in the absence of long waves. We compute probability distributions of short-wave wavenumber given a (frequency, direction) pair and of short-wave frequency given a (wavenumber, direction) pair. These two probability distributions must yield a single spectrum of surface displacements as a function of wavenumber and frequency, F(k,f). We show that the folded, azimuthally averaged version of this spectrum has a "butterfly" pattern in the wavenumber-frequency plane if significant long waves are present. Integration of this spectrum over frequency yields the well-known k-3 wavenumber spectrum. When integrated over wavenumber, the spectrum yields an f-4 form that agrees with measurement. We also show that a cut through the unfolded F(k,f) at constant k produces the well-known form of moderate-incidence-angle Doppler spectra for electromagnetic scattering from the sea. This development points out the dependence of the short-wave spectrum on the amplitude of the long waves.

  17. Orogeny can be very short

    In contrast to continent/continent collision, arc–continent collision generates very short-lived orogeny because the buoyancy-driven impedance of the subduction of continental lithosphere, accompanied by arc/suprasubduction-zone ophiolite obduction, is relieved by subduction polarity reversal (flip). This tectonic principle is illustrated by the early Ordovician Grampian Orogeny in the British and Irish Caledonides, in which a wealth of detailed sedimentologic, heavy mineral, and geochronologic data pin the Orogeny to a very short Arenig/Llanvirn event. The Orogeny, from the initial subduction of continental margin sediments to the end of postflip shortening, lasted ≈18 million years (my). The collisional shortening, prograde-metamorphic phase of the Orogeny lasted 8 my, extensional collapse and exhumation of midcrustal rocks lasted 1.5 my, and postflip shortening lasted 4.5 my. Strain rates were a typical plate-boundary-zone 10-15. Metamorphism, to the second sillimanite isograd, with extensive partial melting, occurred within a few my after initial collision, indicating that conductive models for metamorphic heat transfer in Barrovian terrains are incorrect and must be replaced by advective models in which large volumes of mafic/ultramafic magma are emplaced, syn-tectonically, below and into evolving nappe stacks. Arc/continent collision generates fast and very short orogeny, regional metamorphism, and exhumation. PMID:16126898

    Bendix product applications require the capability of fabricating heavy gage, high strength materials. Five commercial sources have been identified that have the capability of spin forming metal thicknesses greater than 9.5 mm and four equiment manufacturers produce machines with this capability. Twelve assemblies selected as candidates for spin forming applications require spin forming of titanium, 250 maraging steel, 17-4 pH stainless steel, Nitronic 40 steel, 304 L stainless steel, and 6061 aluminum. Twelve parts have been cold spin formed from a 250 maraging steel 8.1 mm wall thickness machine preform, and six have been hot spin formed directly from 31.8-mm-thick flat plate. Thirty-three Ti-6Al-4V titanium alloy parts and 26 17-4 pH stainless steel parts have been hot spin formed directly from 31.8-mm-thick plate. Hot spin forming directly from plate has demonstrated the feasibility and favorable economics of this fabrication technique for Bendix applications.

    An inexpensive pulse generating circuit is disclosed that generates ultra-short, 200 picosecond, and high voltage 100 kW, pulses suitable for wideband radar and other wideband applications. The circuit implements a nonlinear transmission line with series inductors and variable capacitors coupled to ground made from reverse biased diodes to sharpen and increase the amplitude of a high-voltage power MOSFET driver input pulse until it causes non-destructive transit time breakdown in a final avalanche shock wave diode, which increases and sharpens the pulse even more. 5 figures.

    Short range correlations (SRC) are an extremely important part of nuclear structure. They are responsible for the high momentum part of the nuclear wavefunction. Instantaneous densities can significantly exceed the average neutron star density. Recent (e,e[prime]) measurements at Jefferson Lab have shown that SRC are universal in nuclei from deuterium to gold, that the probability of two-nucleon SRC is 5-25%, and that the probability of three-nucleon SRC is less than 1%. Recent (e,e[prime]pn) measurements have measured the SRC probabilities as a function of proton momentum and have measured the joint NN momentum distributions.

  15. Electromagnetic nucleon form factors

    Bender, A.; Roberts, C.D.; Frank, M.R.

    1995-08-01

    The Dyson-Schwinger equation framework is employed to obtain expressions for the electromagnetic nucleon form factor. In generalized impulse approximation the form factor depends on the dressed quark propagator, the dressed quark-photon vertex, which is crucial to ensuring current conservation, and the nucleon Faddeev amplitude. The approach manifestly incorporates the large space-like-q{sup 2} renormalization group properties of QCD and allows a realistic extrapolation to small space-like-q{sup 2}. This extrapolation allows one to relate experimental data to the form of the quark-quark interaction at small space-like-q{sup 2}, which is presently unknown. The approach provides a means of unifying, within a single framework, the treatment of the perturbative and nonperturbative regimes of QCD. The wealth of experimental nucleon form factor data, over a large range of q{sup 2}, ensures that this application will provide an excellent environment to test, improve and extend our approach.

    We propose that entropy is a universal co-homological class in a theory associated to a family of observable quantities and a family of probability distributions. Three cases are presented: 1) classical probabilities and random variables; 2) quantum probabilities and observable operators; 3) dynamic probabilities and observation trees. This gives rise to a new kind of topology for information processes. We discuss briefly its application to complex data, in particular to the structures of information flows in biological systems. This short note summarizes results obtained during the last years by the authors. The proofs are not included, but the definitions and theorems are stated with precision.

The primary goal of this research program, sponsored by the US Department of Energy's Biofuels and Municipal Waste Technology Division, is the development of a viable technology for producing renewable feedstocks for conversion to biofuels. One of the more significant accomplishments was the documentation that short-rotation woody crops total delivered costs could be $40/Mg or less under optimistic but attainable conditions. By taking advantage of federal subsidies such as those offered under the Conservation Reserve Program, wood energy feedstock costs could be lower. Genetic improvement studies are broadening species performance within geographic regions and under less-than-optimum site conditions. Advances in physiological research are identifying key characteristics of species productivity and response to nutrient applications. Recent developments utilizing biotechnology have achieved success in cell and tissue culture, somaclonal variation, and gene-insertion studies. Productivity gains have been realized with advanced cultural studies of spacing, coppice, and mixed-species trials. 8 figs., 20 tabs.

    This program was initiated to replace labor-intensive ply-by-ply layup of composite I-beam posts and angle stiffeners used in the Space Station Freedom (SSF) rack structure. Hot drape forming (HDF) has been successfully implemented by BCAG for 777 composite I-stringers and by Bell Helicopter/Textron for the V-22 I-stingers. The two companies utilize two vastly different approaches to the I-beam fabrication process. A drape down process is used by Bell Helicopter where the compacted ply charge is placed on top of a forming mandrel and heated. When the heated ply charge reached a set temperature, vacuum pressure is applied and the plies are formed over the mandrel. The BCAG 777 process utilizes an inverted forming process where the ply stack is placed on a forming table and the mandrel is inverted and placed upon the ply stack. A heating and vacuum bladder underneath the ply stack form the play stack up onto the mandrels after reaching the temperature setpoint. Both methods have their advantages, but the drape down process was selected for SSF because it was more versatile and could be fabricated from readily available components.

    Many small birds perform short flights, for which take-offs, ascents and descents form a large component of the total flight time and which are characterised by low airspeeds. Using the doubly-labelled water technique, zebra finches Taeniopygia guttata engaging in repeated short flights were found to expend 13.65 kJ more than 'non-flying' controls, which equated to a flight expenditure of 27.8 times their basal metabolic rate. This is over three times the predicted flight expenditure derived from existing aerodynamic models. These data were used to determine a coefficient (0.11) for converting the mechanical power derived from aerodynamic models into metabolic power. An equation is presented, based on body mass, which can be used to predict the costs of short flights in ecological and behavioural studies of birds. PMID:10769218

  5. Observation of short ballistic Josephson effect in vertical graphene junctions

    2014-03-01

    The current-phase relation (CPR) of vertical graphene Josephson junctions (vGJJs) was measured using phase-sensitive dc-SQUID interferometry. A vGJJ, realized by vertically sandwiching a monolayer graphene between two Al electrodes, had an atomically short channel with transparent contacts for the highly coherent junction nature. The measured CPR was almost perfectly skewed, which rigorously confirmed the short ballisticity of the vGJJs. The short ballistic character of a Josephson junction has been predicted since 1970's but has never been realized in scalable hybrid systems. The CPR also provided energy spectrum of Andreev levels formed inside the junction, which offered a promising prospect for scalable quantum information devices such as Andreev-level qubits. This vertical-junction scheme is also readily applicable to the other cleavable materials such as three-dimensional topological insulators or transition metal dichalcogenides, opening a new pathway for uncovering exotic coherence phenomena arising in an atomic scale.

    1995-02-01

    The utility of finite element modeling in optimizing superplastic metal forming is dependent on accurate representation of the material constitutive behavior and the frictional response of the sheet against the die surface. This paper presents work conducted to estimate the level of precision that is necessary in constitutive relations for finite element analysis to accurately predict the deformation history of actual SPF components. Previous work identified errors in SPF testing methods that use short tensile specimens with gauge length-to-width ratios of 2:1 or less. The analysis of the present paper was performed to estimate the error in predicted stress that results from using the short specimens. Stress correction factors were developed and an improved constitutive relation was implemented in the MARC finite element code to simulate the forming of a long, rectangular tray. The coefficient of friction in a Coulomb friction model was adjusted to reproduce the amount of material draw-in observed in the forming experiments. Comparisons between the finite element predictions and the forming experiments are presented.

    This paper is a summary of the activities performed for the process development of laser thermal forming sheet metal parts in support of rapid prototyping. A 400 watt pulsed Nd:YAG laser and 50 watt desktop CO{sub 2} laser were used during initial process development. Several tool-assisted laser forming approaches were conceived during the development of the process, and simple fixtures for process development/understanding were used throughout all testing. Much of the actual forming was performed with the base material in an unfixtured state. CRES (304) was used for baseline development, but the effort was directed toward forming titanium (e.g., 6Al-4V, 15V-3Cr-3Sn-3Al). Several DOE (i.e., Design of Experiment) techniques were employed during development and a Neural Net Computer Model was conceived for process control. This program was a joint effort in cooperation with the American Welding Society under contract with the Defense Advanced Research Projects Agency (DARPA). A synopsis of the laser forming process development, future opportunities, and applications are presented.

    In an effort to learn more about how planets form around their host stars, a team of scientists has analyzed the population of Kepler-discovered exoplanet candidates, looking for trends in where theyre found.Planetary OccurrenceSince its launch in 2009, Kepler has found thousands of candidate exoplanets around a variety of star types. Especially intriguing is the large population of super-Earths and mini-Neptunes planets with masses between that of Earth and Neptune that have short orbital periods. How did they come to exist so close to their host star? Did they form in situ, or migrate inwards, or some combination of both processes?To constrain these formation mechanisms, a team of scientists led by Gijs Mulders (University of Arizona and NASAs NExSS coalition) analyzed the population of Kepler planet candidates that have orbital periods between 2 and 50 days.Mulders and collaborators used statistical reconstructions to find the average number of planets, within this orbital range, around each star in the Kepler field. They then determined how this planet occurrence rate changed for different spectral types and therefore the masses of the host stars: do low-mass M-dwarf stars host more or fewer planets than higher-mass, main-sequence F, G, or K stars?Challenging ModelsAuthors estimates for the occurrence rate for short-period planets of different radii around M-dwarfs (purple) and around F, G, and K-type stars (blue). [Mulders et al. 2015]The team found that M dwarfs, compared to F, G, or K stars, host about half as many large planets with orbital periods of P 50 days. But, surprisingly, they host significantly more small planets, racking up an average of 3.5 times the number of planets in the size range of 12.8 Earth-radii.Could it be that M dwarfs have a lower total mass of planets, but that mass is distributed into more, smaller planets? Apparently not: the authors show that the mass of heavy elements trapped in short-orbital-period planets is higher for M

  10. Electronic cigarettes: a short review.

    PubMed

    Bertholon, J F; Becquemin, M H; Annesi-Maesano, I; Dautzenberg, B

    2013-01-01

    Marketed since 2004 as an alternative to nicotine delivery and advertised as a valid means to smoking cessation, the electronic (e)-cigarette has been the subject of much controversy but very little experimental study. This review provides a brief summary of the current knowledge of this product. Propylene glycol and glycerol, the main ingredients of the fluid that is vaporized, have proved to be harmless in the fog machines of the entertainment industry. However, in the case of the e-cigarette fluid, the composition is not properly labeled: additives like nicotine and flavors vary between and within brands and contamination with various chemicals has been detected. The short-term toxicity seems low, but the long-term toxicity is unknown. The usefulness of the e-cigarette in smoking cessation has still to be clinically established. PMID:24080743

  16. Growth hormone, enhancement and the pharmaceuticalisation of short stature.

    PubMed

    Morrison, Michael

    2015-04-01

    This paper takes the biological drug human Growth Hormone (hGH) as a case study to investigate processes of pharmaceuticalisation and medicalisation in configuring childhood short stature as a site for pharmaceutical intervention. Human growth hormone is considered to have legitimate applications in treating childhood growth hormone deficiency and short stature associated with other recognised conditions. It is also regarded by bioethicists and others as a form of human biomedical enhancement when applied to children with idiopathic or 'normal' short stature. The purpose of this study is not to evaluate whether treatment of idiopathic short stature is enhancement or not, but to evaluate how some applications of hGH in treating short stature have come to be accepted and stabilised as legitimate 'therapies' while others remain contested as 'enhancements'. A comparative, historical approach is employed, drawing on approaches from medical sociology and Science and Technology Studies (STS) to set out a socio-technical history of hGH in the US and UK. Through this history the relative influence and interplay of drivers of pharmaceuticalisation, including industry marketing and networks of drug distribution, and processes of medicalisation will be employed to address this question and simultaneously query the value of enhancement as a sociological concept.

  17. Have protoplanetary discs formed planets?

    NASA Astrophysics Data System (ADS)

    Greaves, J. S.; Rice, W. K. M.

    2010-09-01

    It has recently been noted that many discs around T Tauri stars appear to comprise only a few Jupiter masses of gas and dust. Using millimetre surveys of discs within six local star formation regions, we confirm this result, and find that only a few per cent of young stars have enough circumstellar material to build gas giant planets, in standard core accretion models. Since the frequency of observed exoplanets is greater than this, there is a `missing-mass' problem. As alternatives to simply adjusting the conversion of dust flux to disc mass, we investigate three other classes of solution. Migration of planets could hypothetically sweep up the disc mass reservoir more efficiently, but trends in multiplanet systems do not support such a model, and theoretical models suggest that the gas accretion time-scale is too short for migration to sweep the disc. Enhanced inner-disc mass reservoirs are possible, agreeing with predictions of disc evolution through self-gravity, but not adding to millimetre dust flux as the inner disc is optically thick. Finally, the incidence of massive discs is shown to be higher at the protostellar stages, Classes 0 and I, where discs substantial enough to form planets via core accretion are abundant enough to match the frequency of exoplanets. Gravitational instability may also operate in the Class 0 epoch, where half the objects have potentially unstable discs of >~30 per cent of the stellar mass. However, recent calculations indicate that forming gas giants inside 50 au by instability is unlikely, even in such massive discs. Overall, the results presented suggest that the canonically `protoplanetary' discs of Class II T Tauri stars have globally low masses in dust observable at millimetre wavelengths, and conversion to larger bodies (anywhere from small rocks up to planetary cores) must already have occurred.

  18. Methods for forming particles

    Fox, Robert V.; Zhang, Fengyan; Rodriguez, Rene G.; Pak, Joshua J.; Sun, Chivin

    2016-06-21

    Single source precursors or pre-copolymers of single source precursors are subjected to microwave radiation to form particles of a I-III-VI.sub.2 material. Such particles may be formed in a wurtzite phase and may be converted to a chalcopyrite phase by, for example, exposure to heat. The particles in the wurtzite phase may have a substantially hexagonal shape that enables stacking into ordered layers. The particles in the wurtzite phase may be mixed with particles in the chalcopyrite phase (i.e., chalcopyrite nanoparticles) that may fill voids within the ordered layers of the particles in the wurtzite phase thus produce films with good coverage. In some embodiments, the methods are used to form layers of semiconductor materials comprising a I-III-VI.sub.2 material. Devices such as, for example, thin-film solar cells may be fabricated using such methods.

    2008-10-10

    We first recall the concept of Dyadosphere (electron-positron-photon plasma around a formed black holes) and its motivation, and recall on (i) the Dirac process: annihilation of electron-positron pairs to photons; (ii) the Breit-Wheeler process: production of electron-positron pairs by photons with the energy larger than electron-positron mass threshold; the Sauter-Euler-Heisenberg effective Lagrangian and rate for the process of electron-positron production in a constant electric field. We present a general formula for the pair-production rate in the semi-classical treatment of quantum mechanical tunneling. We also present in the Quantum Electro-Dynamics framework, the calculations of the Schwinger rate and effective Lagrangian for constant electromagnetic fields. We give a review on the electron-positron plasma oscillation in constant electric fields, and its interaction with photons leading to energy and number equipartition of photons, electrons and positrons. The possibility of creating an overcritical field in astrophysical condition is pointed out. We present the discussions and calculations on (i) energy extraction from gravitational collapse; (ii) the formation of Dyadosphere in gravitational collapsing process, and (iii) its hydrodynamical expansion in Reissner Nordstroem geometry. We calculate the spectrum and flux of photon radiation at the point of transparency, and make predictions for short Gamma-Ray Bursts.

    Intensity spikes in Raman scattering, accompanied by switching between line spectra and band spectra, can be assigned to shorting the junction plasmon through molecular conductive bridges. This is demonstrated through Raman trajectories recorded at a plasmonic junction formed by a gold AFM tip in contact with a silver surface coated either with biphenyl-4,4’-dithiol or biphenyl-4-thiol. The fluctuations are absent in the monothiol. In effect, the making and breaking of chemical bonds is tracked.

    A barrier bucket with very short or zero rf-barrier separation (relative to the barrier widths) has its synchrotron tune decreasing from a very large value towards the bucket boundary. As a result, chaotic region may form near the bucket center and extends outward under increasing modulation of rf voltage and/or rf phase. Application is made to those barrier buckets used in momentum mining at the Fermilab Recycler Ring.

By vaporizing and quickly refreezing cryogenic materials contained within a hollow spherical member, a uniform layer of the materials is formed on the inner surface of the spherical member. Heating of the cryogenic material, located within a non-isothermal compact freezing cell, is accomplished by an electrical heat pulse, whereafter the material is quickly frozen forming a uniform layer on the inner surface of the spherical member. The method is not restricted to producing a frozen layer on only the inner surface of the innermost hollow member, but where multiple concentric hollow spheres are involved, such as in multiple shell targets for lasers, electron beams, etc., layers of cryogenic material may also be formed on the inner surface of intermediate or outer spherical members, thus providing the capability of forming targets having multiple concentric layers or shells of frozen DT.

    NASA Astrophysics Data System (ADS)

    The Earth's surface has a dynamic and topographically varied natural landscape. In some cases the resulting landforms are given generic names reflecting their form and/or origin, (e.g. sand dunes, eskers, ox-bow lakes) but in many cases the land surface has a more amorphous form and is less easily categorized other than at a landscape scale (e.g. dissected plateau, Chalk downland). Across much of Europe, while the natural vegetation has been removed or radically modified, the natural land form/topography remains in tact. In this context and in terms of geoconservation we ought to be: • allowing the dynamic natural processes that create, carve and modify landscapes to continue to operate; and • retaining natural topographic character and geomorphological authenticity in the face of human actions seeking to remodel the land surface. In this presentation examples of this approach to geoconservation of land form will be given from the UK and other parts of the world. This will include examples of both appropriate and inappropriate topographic modifications.

    Fisher, Robert W.; Maroone, James P.; Tipping, Donald W.; Zanner, Frank J.

    1986-01-01

    During vacuum consumable arc remelting the electrode gap between a consumable electrode and a pool of molten metal is difficult to control. The present invention monitors drop shorts by detecting a decrease in the voltage between the consumable electrode and molten pool. The drop shorts and their associated voltage reductions occur as repetitive pulses which are closely correlated to the electrode gap. Thus, the method and apparatus of the present invention controls electrode gap based upon drop shorts detected from the monitored anode-cathode voltage. The number of drop shorts are accumulated, and each time the number of drop shorts reach a predetermined number, the average period between drop shorts is calculated from this predetermined number and the time in which this number is accumulated. This average drop short period is used in a drop short period electrode gap model which determines the actual electrode gap from the drop short. The actual electrode gap is then compared with a desired electrode gap which is selected to produce optimum operating conditions and the velocity of the consumable error is varied based upon the gap error. The consumable electrode is driven according to any prior art system at this velocity. In the preferred embodiment, a microprocessor system is utilized to perform the necessary calculations and further to monitor the duration of each drop short. If any drop short exceeds a preset duration period, the consumable electrode is rapidly retracted a predetermined distance to prevent bonding of the consumable electrode to the molten remelt.

  3. Short-form RON overexpression augments benzyl isothiocyanate-induced apoptosis in human breast cancer cells.

    PubMed

    Sehrawat, Anuradha; Singh, Shivendra V

    2016-05-01

    Chemoprevention of breast cancer is feasible with the use of non-toxic phytochemicals from edible and medicinal plants. Benzyl isothiocyanate (BITC) is one such plant compound that prevents mammary cancer development in a transgenic mouse model in association with tumor cell apoptosis. Prior studies from our laboratory have demonstrated a role for reactive oxygen species (ROS)-dependent Bax activation through the intermediary of c-Jun N-terminal kinases in BITC-induced apoptosis in human breast cancer cells. The present study demonstrates that truncated Recepteur d'Origine Nantais (sfRON) is a novel regulator of BITC-induced apoptosis in breast cancer cells. Overexpression of sfRON in MCF-7 and MDA-MB-361 cells resulted in augmentation of BITC-induced apoptosis when the apoptotic fraction was normalized against vehicle control for each cell type (untransfected and sfRON overexpressing cells). ROS generation and G2 /M phase cell cycle arrest resulting from BITC treatment were significantly attenuated in sfRON overexpressing cells after normalization with vehicle control for each cell type. Increased BITC-induced apoptosis by sfRON overexpression was independent of c-Jun N-terminal kinase or p38 mitogen-activated protein kinase hyperphosphorylation. On the other hand, activation of Bax and Bak following BITC exposure was markedly more pronounced in sfRON overexpressing cells than in controls. sfRON overexpression also augmented apoptosis induction by structurally diverse cancer chemopreventive phytochemicals including withaferin A, phenethyl isothiocyanate, and D,L-sulforaphane. In conclusion, the present study provides novel mechanistic insights into the role of sfRON in apoptosis regulation by BITC and other electrophilic phytochemicals. © 2015 Wiley Periodicals, Inc.

    Aim To develop Croatian and Slovenian versions of the 14-item Oral Health Impact Profile (OHIP) Questionnaire. Methods The English original version of the OHIP questionnaire was translated into Croatian (OHIP-CRO14) and Slovenian (OHIP-SVN14) language by a forward-backward translation method. The psychometric properties of the OHIP-CRO14 and OHIP-SVN14 were tested. Concurrent validity was tested on 623 subjects (193 Croatian and 430 Slovenian), test-retest reliability on 115 subjects (55 Croatian and 60 Slovenian), internal consistency on 678 subjects (218 Croatian and 460 Slovenian), and responsiveness on 51 patients (21 Croatian and 30 Slovenian) in demand of treatment (toothache). Results Concurrent validity was confirmed by the association between the OHIP summary scores and self-reported oral health (correlation coefficients ranged from 0.40 to 0.60, P<0.001). Test-retest reliability showed high intraclass correlation (correlation coefficients, 0.79-0.94). Internal consistency showed high Cronbach α (0.77-0.91). Responsiveness was confirmed by a significant difference between the mean OHIP score at baseline and follow-up (P<0.001 for both Croatian and Slovenian patients) and high effect size in Croatian and Slovenian patients in demand of treatment (3.00 and 0.57, respectively). Conclusion Psychometric properties of OHIP-CRO14 and OHIP-SVN14 render these instruments suitable for the assessment of Oral Health Related Quality of Life in Croatia and Slovenia. PMID:18717001

    Applications for the interaction of laser induced plasmas with electromagnetic probes requires time varying complex conductivity data for specific laser/electromagnetic probe geometries. Applications for this data include plasma switching (Q switching) and the study of ionization fronts. The plasmas were created in laboratory air by 100 ps laser pulses at a wavelength of 1 {mu}m. A long focal length lens focused the laser pulse into WR90 (X band) rectangular waveguide. Two different laser beam/electromagnetic probe geometries were investigated. For the longitudinal geometry, the laser pulse and the microwave counterpropagated inside the waveguide. For the transverse geometry, the laser created a plasma ``post`` inside the waveguide. The effects of the laser beam deliberately hitting the waveguide were also investigated. Each geometry exhibits its own characteristics. This research project focused on the longitudinal geometry. Since the laser beam intensity varies inside the waveguide, the charge distribution inside the waveguide also varies. A 10 GHz CW microwave probe traveled through the laser induced plasma. From the magnitude and phase of the microwave probe, a spatially integrated complex conductivity was calculated. No measurements of the temporal or spatial variation of the laser induced plasma were made. For the ``plasma post,`` the electron density is more uniform.

  9. Validation of the Spanish version of the borderline symptom list, short form (BSL-23)

    PubMed Central

    2013-01-01

    Background The Borderline Symptom List-23 (BSL-23) is a reliable and valid self-report instrument for assessing Borderline Personality Disorder (BPD) severity. The psychometric properties of the original version have proven to be adequate. The aim of the present study was to validate the Spanish language version of the BSL-23. Methods The BSL-23 was administered to 240 subjects with BPD diagnosis. Factor structure, reliability, test-retest stability, convergent validity, and sensitivity to change were analyzed. Results The Spanish version of the BSL-23 replicates the one-factor structure of the original version. The scale has high reliability (Cronbach’s alpha=.949), as well as good test-retest stability, which was checked in a subsample (n=74; r=.734; p<.01). The Spanish BSL-23 shows moderate to high correlations with depressive symptomatology, state and trait anxiety, hostility and impulsivity scores and BPD measures. The Spanish BSL-23 is able to discriminate among different levels of BPD severity and shows satisfactory sensitivity to change after treatment, which was verified by assessing change before and after 12 group sessions of Dialectical Behavioral Therapy in a subgroup of 31 subjects. Conclusions Similar to the original BSL-23, the Spanish BSL-23 is a reliable and valid instrument for assessing BPD severity and sensitivity to change. PMID:23672691

    Onboard Short Term Plan Viewer (OSTPV) is a computer program for electronic display of mission plans and timelines, both aboard the International Space Station (ISS) and in ISS ground control stations located in several countries. OSTPV was specifically designed both (1) for use within the limited ISS computing environment and (2) to be compatible with computers used in ground control stations. OSTPV supplants a prior system in which, aboard the ISS, timelines were printed on paper and incorporated into files that also contained other paper documents. Hence, the introduction of OSTPV has both reduced the consumption of resources and saved time in updating plans and timelines. OSTPV accepts, as input, the mission timeline output of a legacy, print-oriented, UNIX-based program called "Consolidated Planning System" and converts the timeline information for display in an interactive, dynamic, Windows Web-based graphical user interface that is used by both the ISS crew and ground control teams in real time. OSTPV enables the ISS crew to electronically indicate execution of timeline steps, launch electronic procedures, and efficiently report to ground control teams on the statuses of ISS activities, all by use of laptop computers aboard the ISS.

    2013-01-01

    Interest in Magnetic Resonance Imaging (MRI) contrast agents for molecular imaging of biological function experienced a surge of excitement approximately 20 years ago with the development of the first activatable contrast agents that could act as biosensors and turn “on” in response to a specific biological activity. This brief tutorial, based on a short course lecture from the 2011 ISMRM meeting, provides an overview of underlying principles governing the design of biosensing contrast agents. We describe mechanisms by which a magnetic resonance imaging (MRI) contrast agent can be made into a sensor for both T1 and T2 types contrast agents. Examples of biological activities that can interact with a contrast agent are discussed using specific examples from the recent literature to illustrate the primary mechanisms of action that have been utilized to achieve activation. MRI sensors for pH, ion binding, enzyme cleavage, and oxidation-reduction are presented. This article is not meant to be an exhaustive review, but an illustrative primer to explain how activation can be achieved for an MRI contrast agent. Chemical exchange saturation transfer (CEST) is not covered as these agents were covered in a separate lecture. PMID:23996662

    Contemporary solidification agents are being investigated relative to their applications to major fuel cycle and non-fuel cycle low-level waste (LLW) streams. Work is being conducted to determine the range of conditions under which these solidification agents can be applied to specific LLW streams. These studies are directed primarily towards defining operating parameters for both improved solidification of problem wastes and solidification of new LLW streams generated from advanced volume reduction technologies. Work is being conducted to measure relevant waste form properties. These data will be compiled and evaluated to demonstrate compliance with waste form performance and shallow land burial acceptance criteria and transportation requirements (both as they exist and as they are modified with time).

    Background Different high-throughput nucleic acid sequencing platforms are currently available but a trade-off currently exists between the cost and number of reads that can be generated versus the read length that can be achieved. Methodology/Principal Findings We describe an experimental and computational pipeline yielding millions of reads that can exceed 200 bp with quality scores approaching that of traditional Sanger sequencing. The method combines an automatable gel-less library construction step with paired-end sequencing on a short-read instrument. With appropriately sized library inserts, mate-pair sequences can overlap, and we describe the SHERA software package that joins them to form a longer composite read. Conclusions/Significance This strategy is broadly applicable to sequencing applications that benefit from low-cost high-throughput sequencing, but require longer read lengths. We demonstrate that our approach enables metagenomic analyses using the Illumina Genome Analyzer, with low error rates, and at a fraction of the cost of pyrosequencing. PMID:20676378

    2007-06-01

    It is well known that a resonance with a large angular life can produce sharp Breit-Wigner peaks in the energy dependence of integral cross sections [1,2]. Here we show that a short-lived resonance whose angular life is of order of one full rotation may produce a different kind of contribution to the integral cross section. This contribution has a sinousoidal form and its frequency is determined by the rotational constant of the complex. As one of the examples, we analyze the Regge oscillations observed in numerical simulations of the F+H2(v=0,j=0,φ=0) ->FH(v'=2,j'=0,φ'=0) + H reaction. In particular, we show that these oscillations are produced by two overlapping resonances located near the transition state and the van der Waals well, respectively [3]. [1] J. H.

    Context: Child dental neglect is a terrible tragedy with a high prevalence. Dealing with this issue is important regarding psychological and physical health policies. The current review was conducted to provide health professionals insight into the different aspects of child dental neglect as reported in previous literature. Evidence Acquisition: Our review was prepared through an electronic search using Pub Med, Science Direct, Medline, Google, Cochran Library, Google Scholar and EMBASE databases. Relevant papers published since 2000 until now in English, discussing child dental neglect were retrieved. Both original and review papers were included. Eligible articles were fully read by the author. A data form was used to record useful findings. Results: Distinguishing the direct and indirect signs of dental neglect is the first step for improvement of this matter. The dental team are the main professionals who can improve parental knowledge about the consequences of child dental neglect. Victims suffer from short and long-term adverse outcomes. Collaborative attempts need to be made by different health professionals to deal with this problem. Conclusions: Child dental neglect has many long-term impacts. The main professionals who are responsible for identification, intervention and treatment of child dental neglect are dental practitioners. However, other professionals cannot ignore this task. Finally, child dental neglect, despite its derivative outcomes, may be a presentation of a broader maltreatment. PMID:25741483

  10. Nucleon Electromagnetic Form Factors

    2004-08-01

    Although nucleons account for nearly all the visible mass in the universe, they have a complicated structure that is still incompletely understood. The first indication that nucleons have an internal structure, was the measurement of the proton magnetic moment by Frisch and Stern (1933) which revealed a large deviation from the value expected for a point-like Dirac particle. The investigation of the spatial structure of the nucleon, resulting in the first quantitative measurement of the proton charge radius, was initiated by the HEPL (Stanford) experiments in the 1950s, for which Hofstadter was awarded the 1961 Nobel prize. The first indication of a non-zero neutron charge distribution was obtained by scattering thermal neutrons off atomic electrons. The recent revival of its experimental study through the operational implementation of novel instrumentation has instigated a strong theoretical interest. Nucleon electro-magnetic form factors (EMFFs) are optimally studied through the exchange of a virtual photon, in elastic electron-nucleon scattering. The momentum transferred to the nucleon by the virtual photon can be selected to probe different scales of the nucleon, from integral properties such as the charge radius to scaling properties of its internal constituents. Polarization instrumentation, polarized beams and targets, and the measurement of the polarization of the recoiling nucleon have been essential in the accurate separation of the charge and magnetic form factors and in studies of the elusive neutron charge form factor.

    The turbulent magnetohydrodynamic flow in the inner regions of a protoplanetary disk forms thin current sheets. These sheets are sites of magnetic reconnection and dissipate the magnetic fields amplified by the disk dynamo. In our own solar system, meteorites record a history of intermittent heating events: meteoritic chondrules were formed in the early Solar System by brief heating of silicate dust to melting temperatures. We suggest that our recently described short-circuit instability concentrates the heating in current sheets enough heat precursor grains for chondrules and other high-temperature minerals. By including the effects of radiative cooling, taking into account the extremely sharp temperature dependency of the opacity, we find two classes of short-circuit event with peak temperatures of ~1600K and ~2100K, set by the dust destruction temperature and the saturation of potassium ionization. The volume-filling nature of turbulent magnetic reconnection is compatible with constraints from formation of high temperature minerals: continuous processing over millions of years in the early solar system, the occurrence of igneous rims, compound chondrules, chondrule-matrix complementarity, and chondrule-chondrule complementarity. The same short-circuit mechanism may perform high-temperature mineral processing continuously in protoplanetary disks, producing not just chondrules but also crystalline silicates and CAIs. As the mechanism is most efficient at the lowest temperatures where the disk is magnetically active, the inner edge of a dead zone is a particularly important region for short-circuit heating events. As the edge of the dead zone moves, both secularly and during outbursts (such as FU Ori), large regions of the inner disk may experience short-circuit heating events.

  12. Electromagnetic pion form factor

    SciTech Connect

    Roberts, C.D.

    1995-08-01

    A phenomenological Dyson-Schwinger/Bethe-Salpeter equation approach to QCD, formalized in terms of a QCD-based model field theory, the Global Color-symmetry Model (GCM), was used to calculate the generalized impulse approximation contribution to the electromagnetic pion form factor at space-like q{sup 2} on the domain [0,10] GeV{sup 2}. In effective field theories this form factor is sometimes understood as simply being due to Vector Meson Dominance (VMD) but this does not allow for a simple connection with QCD where the VMD contribution is of higher order than that of the quark core. In the GCM the pion is treated as a composite bound state of a confined quark and antiquark interacting via the exchange of colored vector-bosons. A direct study of the quark core contribution is made, using a quark propagator that manifests the large space-like-q{sup 2} properties of QCD, parameterizes the infrared behavior and incorporates confinement. It is shown that the few parameters which characterize the infrared form of the quark propagator may be chosen so as to yield excellent agreement with the available data. In doing this one directly relates experimental observables to properties of QCD at small space-like-q{sup 2}. The incorporation of confinement eliminates endpoint and pinch singularities in the calculation of F{sub {pi}}(q{sup 2}). With asymptotic freedom manifest in the dressed quark propagator the calculation yields q{sup 4}F{sub {pi}}(q{sup 2}) = constant, up to [q{sup 2}]- corrections, for space-like-q{sup 2} {approx_gt} 35 GeV{sup 2}, which indicates that soft, nonperturbative contributions dominate the form factor at presently accessible q{sup 2}. This means that the often-used factorization Ansatz fails in this exclusive process. A paper describing this work was submitted for publication. In addition, these results formed the basis for an invited presentation at a workshop on chiral dynamics and will be published in the proceedings.

    A process for forming retrograde and oscillatory profiles in crystalline and polycrystalline silicon. The process consisting of introducing an n- or p-type dopant into the silicon, or using prior doped silicon, then exposing the silicon to multiple pulses of a high-intensity laser or other appropriate energy source that melts the silicon for short time duration. Depending on the number of laser pulses directed at the silicon, retrograde profiles with peak/surface dopant concentrations which vary from 1-1e4 are produced. The laser treatment can be performed in air or in vacuum, with the silicon at room temperature or heated to a selected temperature.

  15. Benchmarking short sequence mapping tools

    PubMed Central

    2013-01-01

    Background The development of next-generation sequencing instruments has led to the generation of millions of short sequences in a single run. The process of aligning these reads to a reference genome is time consuming and demands the development of fast and accurate alignment tools. However, the current proposed tools make different compromises between the accuracy and the speed of mapping. Moreover, many important aspects are overlooked while comparing the performance of a newly developed tool to the state of the art. Therefore, there is a need for an objective evaluation method that covers all the aspects. In this work, we introduce a benchmarking suite to extensively analyze sequencing tools with respect to various aspects and provide an objective comparison. Results We applied our benchmarking tests on 9 well known mapping tools, namely, Bowtie, Bowtie2, BWA, SOAP2, MAQ, RMAP, GSNAP, Novoalign, and mrsFAST (mrFAST) using synthetic data and real RNA-Seq data. MAQ and RMAP are based on building hash tables for the reads, whereas the remaining tools are based on indexing the reference genome. The benchmarking tests reveal the strengths and weaknesses of each tool. The results show that no single tool outperforms all others in all metrics. However, Bowtie maintained the best throughput for most of the tests while BWA performed better for longer read lengths. The benchmarking tests are not restricted to the mentioned tools and can be further applied to others. Conclusion The mapping process is still a hard problem that is affected by many factors. In this work, we provided a benchmarking suite that reveals and evaluates the different factors affecting the mapping process. Still, there is no tool that outperforms all of the others in all the tests. Therefore, the end user should clearly specify his needs in order to choose the tool that provides the best results.

  16. Short-lived Supershear Rupture

    NASA Astrophysics Data System (ADS)

    Fukuyama, E.; Xu, S.; Yamashita, F.; Mizoguchi, K.; Takizawa, S.; Kawakata, H.

    2015-12-01

    Fukuyama and Olsen (2002) computed the supershear rupture initiation, propagation and termination process due to a passage of high stress drop area (called asperity) using a boundary integral equation method. They found that supershear rupture continued to propagate after the passage through high stress drop area but it died after a certain propagation distance, which depends on the elastic energy released at the high stress drop area. Here, we could reproduce a similar phenomenon in the laboratory. We conducted large-scale biaxial friction experiments using a pair of meter-scaled metagabbro rock specimens (VP=6.9km/s, VS=3.6km/s) at the National Research institute for Earth Science and Disaster Prevention (NIED). We observed several stick slip rupture events that initiated close to an asperity and immediately became supershear ruptures. But after propagating certain distance they died out and co-existing subshear ruptures became prominent. If we look into details, during the supershear rupture, we could see a sequence of rupture acceleration, its short rest and re-acceleration. This feature reminds us of a sequential breakage of small high stress patches as predicted by Fukuyama and Madariaga (2000). These observations might be interpreted under a concept of energy balance where the energy transmission from strain energy released by the asperity to fracture energy consumed at the crack tip was not instantaneously balanced in space. This could be related to the fact that earthquake rupture velocity is rather smooth reported from the finite fault analysis of large earthquakes with seismic waveforms. References Fukuyama, E. and R.

    2007-01-01

    The Swift data set on short GRBs has now grown large enough to study correlations of key parameters. The goal is to compare long and short bursts to better understand similarities and differences in the burst origins. In this study we consider the both prompt and afterglow fluxes. It is found that the optical, X-ray and gamma-ray emissions are linearly correlated - stronger bursts tend to have brighter afterglows, and bursts with brighter X-ray afterglow tend to have brighter optical afterglow. Both the prompt and afterglow fluxes are, on average, lower for short bursts than for long. Although there are short GRBs with undetected optical emission, there is no evidence for "dark" short bursts with anomalously low opt/X ratios. The weakest short bursts have a low X-ray/gamma-ray ratio.

    We report the case of a 52-year-old man who presented to our emergency department (ED) after three episodes of syncope in the seven hours before admission. During his stay in the ED he had recurrent ventricular tachycardia (VT) requiring external electrical cardioversion. A 12-lead electrocardiogram (ECG) showed a short QT (SQT) interval (270 ms, QTc 327 ms), with frequent R-on-T extrasystoles triggering sustained polymorphic VT. After exclusion of other precipitating causes, the patient was diagnosed as having SQT syndrome (SQTS) according to the Gollob criteria. To our knowledge, this is the first known documentation of an SQT-caused arrhythmic episode on a 12-lead ECG, as well as the first reported case of SQTS in Portugal. The patient received an implantable cardioverter-defibrillator and was discharged. At a follow-up assessment 14 months later he was symptom-free, interrogation of the device showed no arrhythmic events, and the ECG showed a QT interval of 320 ms (QTc 347 ms). PMID:25442000

    The nucleon form factors are still the subject of active investigation even after an experimental effort spanning 50 years. This is because they are of critical importance to our understanding of the electromagnetic properties of nuclei and provide a unique testing ground for QCD motivated models of nucleon structure. Progress in polarized beams, polarized targets and recoil polarimetry have allowed an important and precise set of data to be collected over the last decade. I will review the experimental status of elastic electron scattering from the nucleon along with an outlook for future progress.

    1975-01-01

    Spacesickness under weightlessness conditions is explained mainly by disruption of the activity of the functional system perceiving space and participating in carrying out the balancing function, consisting, in particular, of the vestibular, proprioceptive, interoceptive, visual and cutaneomechanical analyzers. It can be assumed that, under specific conditions, Coriolis acceleration also is a cause of spacesickness. Adaptation is possible by formation of a new functional system which is adequate to the new mechanical conditions of weightlessness. Selection, training, creation of optimum conditions in the spacecraft cabin, medicinal, and technical improvement of spacecraft play an important role in prophylaxis of the space form of seasickness.

In a triangulated 3-manifold, Haken and Kneser showed that we could put any incompressible surface into normal form. Expanding on those techniques, Rubinstein and Stocking later showed we could put any strongly irreducible surface into almost normal form. Walsh has more recently shown that in an ideal triangulation of a hyperbolic manifold many surfaces can be spun normalized. One unsolved problem in 3-manifold algorithms is studying the complexity of Lens Space Recognition. Spun almost normalization appears to be a part of solving this larger problem. In this dissertation, I will first discuss a nontraditional technique using graphs of equivalence classes of compressing disks that allows us to take a combinatorial approach to generalize the result of Walsh's to nonhyperbolic manifolds. Using that method, I'll also explore the conditions needed to show that a surface can be spun almost normalized.

    The mixed lineage kinase domain-like (MLKL) protein is a key factor in tumor necrosis factor-induced necroptosis. Recent studies on necroptosis execution revealed a commitment role of MLKL in membrane disruption. However, our knowledge of how MLKL functions on membrane remains very limited. Here we demonstrate that MLKL forms cation channels that are permeable preferentially to Mg2+ rather than Ca2+ in the presence of Na+ and K+. Moreover, the N-terminal domain containing six helices (H1-H6) is sufficient to form channels. Using the substituted cysteine accessibility method, we further determine that helix H1, H2, H3, H5 and H6 are transmembrane segments, while H4 is located in the cytoplasm. Finally, MLKL-induced membrane depolarization and cell death exhibit a positive correlation to its channel activity. The Mg2+-preferred permeability and five transmembrane segment topology distinguish MLKL from previously identified Mg2+-permeable channels and thus establish MLKL as a novel class of cation channels.

    Seeley, Karen M

    2004-01-01

    This article examines the challenges specific to short-term intercultural treatments and recently developed approaches to intercultural treatments based on notions of cultural knowledge and cultural competence. The article introduces alternative approaches to short-term intercultural treatments based on ethnographic inquiry adapted for clinical practice. Such approaches allow clinicians conducting short-term intercultural treatments to foreground clients' indigenous conceptions of selfhood, mind, relationship, and emotional disturbance, and thus to more fully grasp their internal, interpersonal, and external worlds. This article demonstrates the uses of clinically adapted ethnographic inquiry in three short-term intercultural cases. PMID:14964524

    Gossypium hirsutum L. cv. Lankart plants exhibited three different types of independent short interval leaf movements which were superimposed on the circadian movements. The different types were termed SIRV (short interval rhythmical vertical), SIHM (short interval horizontal movements), and SHAKE (short stroked SIRV). The 36-minute period SIRV movements occurred at higher moisture levels. The 176-minute period SIHM occurred at lower moisture levels and ceased as the stress increased. The SHAKE movements were initiated with further stresses. The SLEEP (circadian, diurnal) movements ceased with further stress. The last to cease just prior to permanent wilting were the SHAKE movements. PMID:16659123

  7. Improving creativity performance by short-term meditation

    2014-01-01

    Background One form of meditation intervention, the integrative body-mind training (IBMT) has been shown to improve attention, reduce stress and change self-reports of mood. In this paper we examine whether short-term IBMT can improve performance related to creativity and determine the role that mood may play in such improvement. Methods Forty Chinese undergraduates were randomly assigned to short-term IBMT group or a relaxation training (RT) control group. Mood and creativity performance were assessed by the Positive and Negative Affect Schedule (PANAS) and Torrance Tests of Creative Thinking (TTCT) questionnaire respectively. Results As predicted, the results indicated that short-term (30 min per day for 7 days) IBMT improved creativity performance on the divergent thinking task, and yielded better emotional regulation than RT. In addition, cross-lagged analysis indicated that both positive and negative affect may influence creativity in IBMT group (not RT group). Conclusions Our results suggested that emotion-related creativity-promoting mechanism may be attributed to short-term meditation. PMID:24645871

  8. Stimulated Raman Scattering from Short GaP Nanowires

    We report an interesting discovery of very strong non-linear optical behavior in short GaP nanowire segments. They were formed by cutting a ˜40 μm long and 210 nm diameter GaP nanowire into various lengths using a focused ion beam. This approach allows us to study length as the variable in the non-linear behavior. A giant nonlinear Raman amplification has been observed in these segments with length L< 1.2μm for the first time. The nonlinear Raman effect has been demonstrated to increase as the lengths of nanowire segments decreases. As far as the relationship between Raman scattering intensity and laser pump power, we also observed that there exists a threshold pump laser power which separates the linear and super-linear regions. The effective pump power can be as low as 200 μW that is 1000 times smaller than bulk values. We attribute this giant nonlinear Raman effect to stimulated Raman scattering (SRS) from nanocavities formed by these short GaP nanowires. The quality factor Q of these short segments was estimated to be 10^3 to 10^4. We believe our observation suggests the possibility to make a new type of SRS semiconductor laser.

    Einstein described gravitational microlensing in 1936, at the same time suggesting it to be an unobservable phenomenon. He did not foresee technological advancements that would lead to microlensing becoming a productive tool for astronomy. Of particular interest may be the role it has begun to play in the discovery of rogue planets - exoplanets that are not bound to a star or stars. Rogue planets may be formed independently, or they may be formed in the confines of a stellar system and then ejected by gravitational interactions. Currently fewer than a dozen rogue planets are known but estimates of their abundance conservatively start at double the number of stars in our galaxy.The Optical Gravitational Lensing Experiment (OGLE) and Microlensing Observations in Astrophysics (MOA) teams have collectively detected approximately 2500 events this year alone. A significant portion of these events are of short duration, with an Einstein crossing time of less than 10 days. Microlensing events generally occur on a timescale of weeks to months, so short duration events are an interesting class for study, particularly with regard to searches for rogue planets. We have undertaken a systematic study and categorization of the short duration microlensing events from recent OGLE and MOA alerts, with a special eye to identifying exoplanet candidates.

    An apparatus is provided for forming gas-filled spheres of metal, glass or other material, which produces spheres (12) of uniform size and wall thickness in a relatively simple system. The system includes concentric nozzles, including an inner nozzle (18) through which gas flows and and an outer nozzle (20), which jointly define an annular passageway (50) through which a liquid flows. The flow rates are adjusted so that the gas flows at greater velocity than does the liquid, out of their respective nozzles, e.g. three times as great, in order to produce an extrusion (30) which undergoes axisymmetric oscillations resulting in the pinch off into hollow spheres with very uniform spacing. The system is useful not only where gas-filled spheres are required, but also is useful to accurately control the dispensing of solid, liquid, or gaseous materials.

    A nozzle assembly is described for use in a system that forms small gas-filled shells, which avoids the need for holding a miniature inner nozzle precisely concentric with a miniature outer nozzle. The outer nozzle has a diameter which is less than about 0.7 millimeter, which results in fluid passing through the nozzle having a progressively greater velocity at locations progressively further from the walls of the outer nozzle across most of the nozzle. This highly variable velocity profile automatically forces gas to the center of the outer nozzle. The end of the inner nozzle, which emits gas, is spaced upstream from the tip of the outer nozzle, to provide a distance along which to center the gas. This self-centering characteristic permits the inner nozzle to be positioned so its axis is not concentric with the axis of the outer nozzle.

    It is pointed out that the correct criterion to define the legal PQCD contribution to the exclusive processes in the lightcone perturbative expansion should be based on the large off-shellness of the lightcone energy in the intermediate states. In the lightcone perturbative QCD calculation of the pion form factor, the authors find that the legal PQCD contribution defined by the lightcone energy cut saturates in the smaller Q{sup 2} region compared to that defined by the gluon four-momentum square cut. This is due to the contribution by the highly off-energy-shell gluons in the end point regions of the phase space, indicating that the gluon four-momentum-square cut may have cut too much to define the legal PQCD.

    There has been much activity in the measurement of the elastic electromagnetic proton and neutron form factors in the last decade, and the quality of the data has greatly improved by performing double polarization experiments, in comparison with previous unpolarized data. Here we review the experimental data base in view of the new results for the proton, and neutron, obtained at JLab, MAMI, and MIT-Bates. The rapid evolution of phenomenological models triggered by these high-precision experiments will be discussed, including the recent progress in the determination of the valence quark generalized parton distributions of the nucleon, as well as the steady rate of improvements made in the lattice QCD calculations.

  15. Spray-formed tooling

    NASA Astrophysics Data System (ADS)

    McHugh, K. M.; Key, J. F.

    The United States Council for Automotive Research (USCAR) has formed a partnership with the Idaho National Engineering Laboratory (INEL) to develop a process for the rapid production of low-cost tooling based on spray forming technology developed at the INEL. Phase 1 of the program will involve bench-scale system development, materials characterization, and process optimization. In Phase 2, prototype systems will be designed, constructed, evaluated, and optimized. Process control and other issues that influence commercialization will be addressed during this phase of the project. Technology transfer to USCAR, or a tooling vendor selected by USCAR, will be accomplished during Phase 3. The approach INEL is using to produce tooling, such as plastic injection molds and stamping dies, combines rapid solidification processing and net-shape materials processing into a single step. A bulk liquid metal is pressure-fed into a de Laval spray nozzle transporting a high velocity, high temperature inert gas. The gas jet disintegrates the metal into fine droplets and deposits them onto a tool pattern made from materials such as plastic, wax, clay, ceramics, and metals. The approach is compatible with solid freeform fabrication techniques such as stereolithography, selective laser sintering, and laminated object manufacturing. Heat is extracted rapidly, in-flight, by convection as the spray jet entrains cool inert gas to produce undercooled and semi-solid droplets. At the pattern, the droplets weld together while replicating the shape and surface features of the pattern. Tool formation is rapid; deposition rates in excess of 1 ton/h have been demonstrated for bench-scale nozzles.

    What causes the large-scale spiral structures found in some protoplanetary disks? Most models assume theyre created by newly-forming planets, but a new study suggests that planets might have nothing to do with it.Perturbations from Planets?In some transition disks protoplanetary disks with gaps in their inner regions weve directly imaged large-scale spiral arms. Many theories currently attribute the formation of these structures to young planets: either the direct perturbations of a planet embedded in the disk cause the spirals, or theyre indirectly caused by the orbit of a planetary body outside of the arms.Another example of spiral arms detected in a protoplanetary disk, MWC 758. [NASA/ESA/ESO/M. Benisty et al.]But what if you could get spirals without any planets? A team of scientists led by Matas Montesinos (University of Chile) have recently published a study in which they examine what happens to a shadowed protoplanetary disk.Casting Shadows with WarpsIn the teams setup, they envision a protoplanetary disk that is warped: the inner region is slightly tilted relative to the outer region. As the central star casts light out over its protoplanetary disk, this disk warping would cause some regions of the disk to be shaded in a way that isnt axially symmetric with potentially interesting implications.Montesinos and collaborators ran 2D hydrodynamics simulations to determine what happens to the motion of particles within the disk when they pass in and out of the shadowed regions. Since the shadowed regions are significantly colder than the illuminated disk, the pressure in these regions is much lower. Particles are therefore accelerated and decelerated as they pass through these regions, and the lack of axial symmetry causes spiral density waves to form in the disk as a result.Initial profile for the stellar heating rate per unit area for one of the authors simulations. The regions shadowed as a result of the disk warp subtend 0.5 radians each (shown on the left
