    There is growing evidence that individual differences among patients with major depressive disorder (MDD) on psychological and demographic measures may predict the therapeutic response to selective serotonin reuptake inhibitors (SSRIs). In this retrospective chart review, 108 outpatients with current major depressive episodes were treated with citalopram, paroxetine, or fluvoxamine. The Hamilton Depression Rating Scale and the Minnesota Multiphasic Personality Inventory-2 were administered before and after 8 weeks of SSRIs treatment. Clinical response was defined as a 50% or greater decrease in the 17-item Hamilton Depression Rating Scale total score (final visit minus baseline). This naturalistic short-term follow-up outcome study demonstrates that among depressive outpatients who responded to an 8-week trial, 57.4% achieved a good response to SSRIs. Statistical analysis showed that SSRI treatment may be 3.03 times more advantageous for MDD outpatients who are younger than 39 years. The patients with an elevated score of above 66T on the Social Introversion Minnesota Multiphasic Personality Inventory-2 scale are approximately 0.37 times as likely to be SSRI responders as are patients with a Social Introversion score less than 66T. Thus, it seems that in MDD outpatient age is the strongest predictor of response to SSRIs. PMID:22415223

    Patients with left hemisphere disease have been noted to be depressed while those with right hemisphere disease appear indifferent. While patients with left hemisphere disease frequently have a greater cognitive deficit, patients with right hemisphere disease have difficulty in expressing affectively intoned speech. The Minnesota Multiphasic Personality Inventory (MMPI) can demonstrate underlying affective experience and is not dependent on affectively intoned speech. The purpose of this study was to determine whether a difference in affective moods, as assessed by the MMPI, was related to laterality of lesion in patients matched for severity of cognitive and motor dysfunction. Seven of the 16 subjects with left hemisphere dysfunction and none of the eight subjects with right hemisphere dysfunction showed an elevation on the depression scale. This observation not only confirms previous clinical observations but also demonstrates that these asymmetries cannot be ascribed completely to hemisphere-related differences in cognitive deficits or expressive abilities.

    In a study designed to assess personality patterns of patients with chronic insomnia, a total of 528 subjects (428 insomniacs and 100 controls) completed the Minnesota Multiphasic Personality Inventory (MMPI). Comparison of the MMPI profiles of insomniacs from a semirural area and of those from an urban area, each in a completely different geographic region, showed results consistent for high levels of psychopathology as well as for specific personality patterns within and between groups. The personality patterns of insomniac subjects were remarkably homogeneous: only a few MMPI code types accounted for about one-half of each insomniac sample. The insomniac profiles were consistently characterized by the presence of neurotic depression, rumination, chronic anxiety, inhibition of emotions, and an inability to discharge anger outwardly. The results of this study confirm the original hypothesis that the handling of stresses and conflicts through an internalization of emotions leads to physiologic activation and is a major factor underlying the development and maintenance of chronic insomnia.

    The purpose of this study was to investigate the predictive validity of the Minnesota Multiphasic Personality Inventory-2-Restructured Form (MMPI-2-RF) in a sample of law enforcement officers. MMPI-2-RF scores were collected from preemployment psychological evaluations of 136 male police officers, and supervisor ratings of performance and problem behavior were subsequently obtained during the initial probationary period. The sample produced meaningfully lower and less variant substantive scale scores than the general population and the MMPI-2-RF Police Candidate comparison group, which significantly affected effect sizes for the zero-order correlations. After applying a correction for range restriction, MMPI-2-RF substantive scales demonstrated moderate to strong associations with criteria, particularly in the Emotional Dysfunction and Interpersonal Functioning domains. Relative risk ratio analyses showed that cutoffs of 45T and 50T maintained reasonable selection ratios because of the exceptionally low scores in this sample and were associated with significantly increased risk for problematic behavior. These results provide support for the predictive validity of the MMPI-2-RF substantive scales in this setting. Implications of these findings and limitations of these results are discussed.

    2016-04-01

    The reliability of six Minnesota Multiphasic Personality Inventory-Second edition (MMPI-2) computer-based test interpretation (CBTI) programs was evaluated across a set of 20 commonly appearing MMPI-2 profile codetypes in clinical settings. Evaluation of CBTI reliability comprised examination of (a) interrater reliability, the degree to which raters arrive at similar inferences based on the same CBTI profile and (b) interprogram reliability, the level of agreement across different CBTI systems. Profile inferences drawn by four raters were operationalized using q-sort methodology. Results revealed no significant differences overall with regard to interrater and interprogram reliability. Some specific CBTI/profile combinations (e.g., the CBTI by Automated Assessment Associates on a within normal limits profile) and specific profiles (e.g., the 4/9 profile displayed greater interprogram reliability than the 2/4 profile) were interpreted with variable consensus (α range = .21-.95). In practice, users should consider that certain MMPI-2 profiles are interpreted more or less consensually and that some CBTIs show variable reliability depending on the profile. PMID:25944798

    The use of response bias indicators in psychological measurement has been contentious, with debate as to whether they actually suppress or moderate the ability of substantive psychological indicators to identify the construct of interest. Suppression would indicate that predictor variables contain invalid variance that the bias indicators can suppress, while moderation would indicate differential levels of predictive validity at different levels of bias. Response bias indicators on the Minnesota Multiphasic Personality Inventory (MMPI)-2-Restructured Form (MMPI-2-RF) [infrequent responses (F-r), infrequent somatic responses (Fs), infrequent psychopathology responses (Fp-r), adjustment validity (K-r), uncommon virtues (L-r), symptom validity (FBS-r), and Response Bias Scale (RBS)] were tested to determine whether they suppressed or moderated the ability of the Restructured Clinical Scale 1 (RC1) and Neurologic Complaints (NUC) scale to discriminate between epileptic seizures (ES) and nonepileptic seizures (NES, a conversion disorder that is often misdiagnosed as ES). The MMPI-2-RF was completed by 399 patients with a confirmed diagnosis of ES or NES via Epilepsy Monitoring Unit evaluation. Moderated logistic regression was used to test for moderation, and logistic regression was used to test for suppression. Most of the response bias variables showed a suppressor effect, but moderator effects were not found. These findings extend the use of bias indicators to a psychomedical context. PMID:25730164

    We compared Minnesota Multiphasic Personality Inventory-2-Restructured Form (MMPI-2-RF) scores of 25 individuals convicted of felonies who violated probation within 1 year of sentencing with those of 45 similarly sentenced defendants who completed probation successfully. The sample (51 males, 19 females) ranged in age from 18 to 81 years (M = 35.2, SD = 13.8) and had 8 to 16 years of education (M = 11.7, SD = 2.1). The majority were Caucasian (85.7%), but African Americans were also represented (14.3%). Individuals in the sample were primarily convicted of mid-level felonies (F-1: 2.9%; F-2: 14.3%; F-3: 22.9%; F-4: 31.4%; F-5: 12.9%). As hypothesized, moderate to large statistically significant differences between probation completers and violators were found on several MMPI-2-RF scales, including Behavioral/Externalizing Dysfunction, Antisocial Behavior, Juvenile Conduct Problems, Substance Abuse, Aggression, Activation, and Disconstraint. Relative risk ratio analyses indicated that probationers who produced elevated scores on these scales were up to 3 times more likely to violate probation than were those with non-elevated scores. Implications of these results and limitations of our findings are discussed. PMID:25133459

    Our aim in the current study was to evaluate the convergence between Diagnostic and Statistical Manual of Mental Disorders, fifth edition (DSM-5) Section III dimensional personality traits, as operationalized via the Personality Inventory for DSM-5 (PID-5), and Minnesota Multiphasic Personality Inventory 2-Restructured Form (MMPI-2-RF) scale scores in a psychiatric patient sample. We used a sample of 346 (171 men, 175 women) patients who were recruited through a university-affiliated psychiatric facility in Toronto, Canada. We estimated zero-order correlations between the PID-5 and MMPI-2-RF substantive scale scores, as well as a series of exploratory structural equation modeling (ESEM) analyses to examine how these scales converged in multivariate latent space. Results generally showed empirical convergence between the scales of these two measures that were thematically meaningful and in accordance with conceptual expectations. Correlation analyses showed significant associations between conceptually expected scales, and the highest associations tended to be between scales that were theoretically related. ESEM analyses generated evidence for distinct internalizing, externalizing, and psychoticism factors across all analyses. These findings indicate convergence between these two measures and help further elucidate the associations between dysfunctional personality traits and general psychopathology. PMID:25822829

    Minnesota Multiphasic Personality Inventory-2-Restructured Form scores for 145 male police officer candidates were compared with supervisor ratings of field performance and problem behaviors during their initial probationary period. Results indicated that the officers produced meaningfully lower and less variant substantive scale scores compared to the general population. After applying a statistical correction for range restriction, substantive scale scores from all domains assessed by the inventory demonstrated moderate to large correlations with performance criteria. The practical significance of these results was assessed with relative risk ratio analyses that examined the utility of specific cutoffs on scales demonstrating associations with performance criteria.

    The current study examined the predictive validity of Minnesota Multiphasic Personality Inventory-2-Restructured Form (MMPI-2-RF; Ben-Porath & Tellegen, 2008/2011) scores in police officer screenings. We utilized a sample of 712 police officer candidates (82.6% male) from 2 Midwestern police departments. The sample included 426 hired officers, most of whom had supervisor ratings of problem behaviors and human resource records of civilian complaints. With the full sample, we calculated zero-order correlations between MMPI-2-RF scale scores and scale scores from the California Psychological Inventory (Gough, 1956) and Inwald Personality Inventory (Inwald, 2006) by gender. In the hired sample, we correlated MMPI-2-RF scale scores with the outcome data for males only, owing to the relatively small number of hired women. Several scales demonstrated meaningful correlations with the criteria, particularly in the thought dysfunction and behavioral/externalizing dysfunction domains. After applying a correction for range restriction, the correlation coefficient magnitudes were generally in the moderate to large range. The practical implications of these findings were explored by means of risk ratio analyses, which indicated that officers who produced elevations at cutscores lower than the traditionally used 65 T-score level were as much as 10 times more likely than those scoring below the cutoff to exhibit problem behaviors. Overall, the results supported the validity of the MMPI-2-RF in this setting. Implications and limitations of this study are discussed. PMID:25383586

We calculated internal consistency coefficients, mean-item correlations, and SEM for all substantive scales, as well as zero-order correlations with collateral medical record information and self-report testing. Results indicated reliability and validity for most of the MMPI-2-RF substantive scales. Implications of these findings and limitations of this study are discussed. PMID:25436662

    The 28-item Response Bias Scale (RBS) and 15-item Henry-Heilbronner Index (HHI) are new validity scales within the Minnesota Multiphasic Personality Inventory-2, designed to detect over-reporting of cognitive and somatic symptomology, respectively. The 43-item Lees-Haley Fake Bad Scale (FBS) was designed to detect noncredible symptom presentations within a personal injury setting. The current study examined the predictive validity of these scales in a criterion-groups design involving head-injured litigants. Archival data were collected and two groups were created using the Slick, Sherman, and Iverson ([1999].

Results yielded excellent to acceptable discrimination ability for the validity scales, including an area under the curve of 0.83 for FBS, 0.82 for RBS, and 0.73 for HHI. Findings suggest that the FBS, RBS, and HHI perform as well as the other validity scales in discriminating over-reporting within a head-injured litigant setting. PMID:21148668

    We examined associations between prehire Minnesota Multiphasic Personality Inventory-2-Restructured Form (MMPI-2-RF) scores and posthire performance ratings for a sample of 131 male police officers. Substantive scale scores in this sample were meaningfully lower than those obtained by the test's normative sample and substantially range restricted, but scores were consistent with those produced by members of the police candidate comparison group (Corey & Ben-Porath). After applying a statistical correction for range restriction, we found several associations between MMPI-2-RF substantive scale scores and supervisor ratings of job-related performance. Findings for scales from the emotional dysfunction and interpersonal functioning domains of the test were particularly strong. For example, scales assessing low positive emotions and social avoidance were associated with several criteria that may be affected by lack of engagement with one's environment and other people, including problems with routine task performance, decision making, assertiveness, conscientiousness, and social competence. Implications of these findings for assessment science and practice are discussed. PMID:25169624

    A substantial proportion of individuals who undergo surgical procedures to relieve spine pain continue to report significant pain and dysfunction after recovery. Psychopathology and patient expectations have been linked to poor results, leading to an increasing reliance on presurgical psychological screening (PPS) as part of the surgical diagnostic process. The original Minnesota Multiphasic Personality Inventory (MMPI; Hathaway & McKinley, 1943) and the MMPI-2 (Butcher, Graham, Ben-Porath, Tellegen, & Dahlstrom, 2001) were among the measures most commonly used in PPS evaluations and research. This study focuses on the newest version of the test, the MMPI-2-Restructured Form (MMPI-2-RF; Ben-Porath & Tellegen, 2008/2011; Tellegen & Ben-Porath, 2008/2011) as a predictor of outcomes for spine surgery candidates. Using a sample of 172 men and 210 women who underwent a PPS, we examined the ability of MMPI-2-RF scale scores to predict early surgical outcomes independent of other presurgical risk factors identified by other means, as well as patients' presurgical expectations. MMPI-2-RF results accounted for up to 11% of additional variance in measures of early postoperative functioning. MMPI-2-RF scales that assess for emotional/internalizing problems, specifically Demoralization, measures of somatoform dysfunction, and interpersonal problems contributed most to the prediction of diminished outcome.

    Misinterpretation of non-content-based invalid (e.g., random, fixed) responding as overreporting or underreporting is likely to adversely impact test interpretation and could bias inferences about examinee intentions. We examined the impact of non-content-based invalid responding on the following Minnesota Multiphasic Personality Inventory-2 Restructured Form (MMPI-2-RF) content-based invalid responding indicators: Infrequent Responses (F-r), Infrequent Psychopathology Responses (FP-r), Infrequent Somatic Responses (FS), Symptom Validity (FBS-r), Response Bias Scale (RBS), Uncommon Virtues (L-r), and Adjustment Validity (K-r). In 4 samples from which invalid responders were excluded, we systematically inserted increasing percentages of random, acquiescent, or counter-acquiescent item responses ranging from 0% to 100% and examined the impact that non-content-based invalid response styles had on the content-based invalid responding indicators. F-r, FP-r, FS, RBS, and L-r were susceptible to non-content-based invalid responding, whereas FBS-r and K-r were unaffected. Individuals with Variable Response Inconsistency (VRIN-r) and True Response Inconsistency (TRIN-r) elevations were removed, and the frequencies of content-based invalid responding elevations were then reexamined for false indications of feigning. Findings were consistent across samples and emphasize the need to screen for non-content-based invalid responding before screening for content-based invalid responding in the assessment of personality and psychopathology. VRIN-r and TRIN-r were useful in detecting most-but not all-cases of non-content-based invalid responding. A small but meaningful percentage of the remaining individuals were misclassified as overreporters (i.e., false feigners) by FP-r and FS. Clinicians should interpret FP-r and FS with some caution in the presence of moderate levels of non-content-based invalid responding. Post hoc examinations of scale characteristics indicated that the most

    Objective personality tests, such as the Minnesota Multiphasic Personality Inventory (MMPI), might be more sensitive to reflect subclinical personality and be more state-dependent in an individual's lifetime, so they are good scales to predict the psychological distress regarding certain states. The aim of this study was to identify the specific pattern between body mass index (BMI) and psychological distress using the objective personality test. For this study, we investigated BMI and the Korean Military Multiphasic Personality Inventory (MPI). A retrospective cross-sectional study was conducted with 19-yr-old examinees who were admitted to the Military Manpower Administration in Korea from February 2007 to January 2010. Of 1,088,107 examinees, we enrolled 771,408 subjects who were psychologically apparent healthy possible-military-service groups. Afterwards, we reviewed and analyzed directly measured BMI and MPI results. In terms of the validity scales, the faking-good subscale showed an inverted U-shaped association, and faking-bad and infrequency subscales showed a U-shaped association with BMI groups. In terms of the neurosis scales, all clinical subscales (anxiety, depression, somatization, and personality disorder) also showed a U-shaped association with BMI groups. For the psychopath scales, the schizophrenia subscale showed a U-shaped association, and the paranoia subscale showed a near-positive correlation with BMI. In conclusion, a specific U-shaped pattern was observed between BMI and the MPI in 19-yr-old men in Korea. Underweight and obesity are related to psychological distress, so supportive advice and education are needed to them. PMID:26028934

    We investigated the internal structure comparability of Minnesota Multiphasic Personality Inventory-2-Restructured Form (MMPI-2-RF) scores derived from the MMPI-2 and MMPI-2-RF booklets in a sample of 320 criminal defendants (229 males and 54 females). After exclusion of invalid protocols, the final sample consisted of 96 defendants who were administered the MMPI-2-RF booklet and 83 who completed the MMPI-2. No statistically significant differences in MMPI-2-RF invalidity rates were observed between the two forms. Individuals in the final sample who completed the MMPI-2-RF did not statistically differ on demographics or referral question from those who were administered the MMPI-2 booklet. Independent t tests showed no statistically significant differences between MMPI-2-RF scores generated with the MMPI-2 and MMPI-2-RF booklets on the test's substantive scales. Statistically significant small differences were observed on the revised Variable Response Inconsistency (VRIN-r) and True Response Inconsistency (TRIN-r) scales. Cronbach's alpha and standard errors of measurement were approximately equal between the booklets for all MMPI-2-RF scales. Finally, MMPI-2-RF intercorrelations produced from the two forms yielded mostly small and a few medium differences, indicating that discriminant validity and test structure are maintained. Overall, our findings reflect the internal structure comparability of MMPI-2-RF scale scores generated from MMPI-2 and MMPI-2-RF booklets. Implications of these results and limitations of these findings are discussed. PMID:24934218

  13. A critical review of objective personality inventories with sex offenders.

    Davis, Karen M; Archer, Robert P

    2010-12-01

    This review provides a critical analysis of the ability of multiscale inventories to distinguish between sex offender and nonoffender control groups, as well as to discriminate sex offenders from other types of offenders. In addition to expanding upon previous reviews that examined the utility of the Minnesota Multiphasic Personality Inventory (MMPI) with this population (e.g., Levin & Stava, 1987), the current review included studies that utilized other multiscale inventories commonly used in forensic practice (i.e., MMPI-2, Millon Clinical Multiaxial Inventory-III [MCMI-III], Personality Assessment Inventory) and, when possible, provides effect sizes to evaluate group differences. Based on the review, the various forms of the MMPI and MCMI are clearly the most widely used instruments in sex offender populations. The MMPI Pd scale has shown moderate to large effect sizes when distinguishing between sex offender and nonsex offender groups, but this relationship may be reflective of antisocial behavior in general rather than traits specific to sex offenders. Recommendations to standardize future research classification strategies and more effectively utilize these instruments when assessing sex offenders are also provided. PMID:20734319

    Minnesota Multiphasic Inventory 2 (MMPI-2) scale 3, duration of illness, and routine EEGs have been used to predict nonepileptic events (NEEs) with a high degree of accuracy in patients referred for video/EEG (vEEG) monitoring. This study tested the Storzbach logistic regression equation in our patients with definitive epileptic seizures (n=57) or NEEs without evidence of epileptiform activity (n=51) during vEEG monitoring, yielding an overall classification accuracy of 81%, sensitivity of 80%, and specificity of 81%. This study also replicated previous findings of significant group differences in duration (years) of spells, number of elevations on the MMPI-2, MMPI-2 elevations on scales 1, 2, 3, and 8, and incidence of the conversion valley on the MMPI-2. Our findings indicated that combined use of the MMPI-2 and clinical variables was most predictive of patients with NEEs. PMID:17904912

    2012-01-01

    The aim of the present study was to test the cross-cultural validity of the five-factor nature of personality. For this aim, an indigenous, psychometrically strong instrument measuring the basic personality dimensions within Turkish culture and language was developed through three consecutive studies. The first study aimed to reveal the adjectives that have been most frequently used to define people in the Turkish culture. In the second study, factor analysis of these personality characteristics revealed big five personality factors, along with the sixth factor, which had been called as the Negative Valence factor. The adjectives that most strongly represented and differentiated each factor constituted 45-item "Basic Personality Traits Inventory". Finally, in the third study, psychometric characteristics of the Basic Personality Traits Inventory were examined. Factor structure and psychometric properties of this instrument confirmed that five-factor nature of personality may not hold true in every culture. PMID:24837020

    Valid self-report assessment of psychopathology relies on accurate and credible responses to test questions. There are some individuals who, in certain assessment contexts, cannot or choose not to answer in a manner typically representative of their traits or symptoms. This is referred to, most broadly, as test response bias. In this investigation, we explore the effect of response bias on the Personality Inventory for DSM-5 (PID-5; Krueger, Derringer, Markon, Watson, & Skodol, 2013 ), a self-report instrument designed to assess the pathological personality traits used to inform diagnosis of the personality disorders in Section III of DSM-5. A set of Minnesota Multiphasic Personality Inventory Restructured Form (MMPI-2-RF; Ben-Porath & Tellegen, 2008 / 2011 ) validity scales, which are used to assess and identify response bias, were employed to identify individuals who engaged in either noncredible overreporting (OR) or underreporting (UR), or who were deemed to be reporting or responding to the items in a "credible" manner-credible responding (CR). A total of 2,022 research participants (1,587 students, 435 psychiatric patients) completed the MMPI-2-RF and PID-5; following protocol screening, these participants were classified into OR, UR, or CR response groups based on MMPI-2-RF validity scale scores. Groups of students and patients in the OR group scored significantly higher on the PID-5 than those students and patients in the CR group, whereas those in the UR group scored significantly lower than those in the CR group. Although future research is needed to explore the effects of response bias on the PID-5, results from this investigation provide initial evidence suggesting that response bias influences scale elevations on this instrument.

    2013-01-01

    Assessing patients with dissociative disorders (DD) using personality tests is difficult. On the Minnesota Multiphasic Personality Inventory-2 ( J. N. Butcher, W. G. Dahlstrom, J. R. Graham, A. Tellegen, & B. Kaemmer, 1989 ), DD patients often obtain elevations on multiple clinical scales as well as on validity scales that were thought to indicate exaggeration yet have been shown to be elevated among traumatized individuals, including those with DD. No research has been conducted to determine how DD patients score on the Personality Assessment Inventory (PAI; L. C. Morey, 1991 ), which includes the symptom exaggeration scale Negative Impression (NIM) and the malingering scales Malingering Index (MAL) and Rogers Discriminant Function (RDF). The goals of this study were to document the PAI profile of dissociative identity disorder (DID) and dissociative disorder not otherwise specified (DDNOS) patients and to determine how the validity and Schizophrenia scales are related to other PAI scales as well as dissociation. A total of 42 inpatients with DID or DDNOS were assessed on the PAI as well as the Dissociative Experiences Scale-II. The DID/DDNOS patients were elevated on many PAI scales, including NIM and, to a lesser extent, MAL, but not RDF. Dissociation scores significantly and uniquely predicted NIM scores above and beyond Depression and Borderline Features. In addition, after we controlled for MAL and RDF, dissociation was positively associated with NIM. In contrast, after we controlled for the other 2 scales, dissociation was not related to MAL and was negatively related to RDF, indicating that RDF and, to a lesser extent, MAL are better correlates of feigning in DD patients than NIM.

  14. Social desirability in personality inventories: Symptoms, diagnosis and prescribed cure

    PubMed Central

    Bäckström, Martin; Björklund, Fredrik

    2013-01-01

    An analysis of social desirability in personality assessment is presented. Starting with the symptoms, Study 1 showed that mean ratings of graded personality items are moderately to strongly linearly related to social desirability (Self Deception, Impression formation, and the first Principal Component), suggesting that item popularity may be a useful heuristic tool for identifying items which elicit socially desirable responding. We diagnose the cause of socially desirable responding as an interaction between the evaluative content of the item and enhancement motivation in the rater. Study 2 introduced a possible cure; evaluative neutralization of items. To test the feasibility of the method lay psychometricians (undergraduates) reformulated existing personality test items according to written instructions. The new items were indeed lower in social desirability while essentially retaining the five factor structure and reliability of the inventory. We conclude that although neutralization is no miracle cure, it is simple and has beneficial effects. PMID:23252410

    Two studies summarize the development and initial validation of the Multicultural Personality Inventory (MPI). In Study 1, the 115-item prototype MPI was administered to 415 university students where exploratory factor analysis resulted in a 70-item, 7-factor model. In Study 2, the 70-item MPI and theoretically related companion instruments were administered to a multisite sample of 576 university students. Confirmatory factory analysis found the 7-factor structure to be a relatively good fit to the data (Comparative Fit Index =.954; root mean square error of approximation =.057), and MPI factors predicted variance in criterion variables above and beyond the variance accounted for by broad personality traits (i.e., Big Five). Study limitations and directions for further validation research are specified. PMID:24206108

    1998-03-01

    The revised Personal Style Inventory (PSI) was developed to measure the sociotropy and autonomy personality dimensions; both of these dimensions are thought to confer specific vulnerabilities to the onset, maintenance, and reoccurrence of depression. Confirmatory factor analysis was used to test the theoretical structure that informed the construction of the PSI. Using a large sample of nonclinical participants (n = 869) and a sample of outpatients with major depression (n = 101), both the items and the subscales of the PSI decomposed into factor structures that were, overall, fair to good representations of the theoretical model. Modifications were needed at the subscale level to achieve an adequate fit for the nonclinical and clinical samples, which provide implications for both the measurement and theory of the PSI and the sociotropy and autonomy domains.

    Background: Ayurveda inventories for prakriti (constitution) have been developed and validated for adults. Children, however, require different categories of quarter and questions, for example, to assess the intelligence, the questions can be related to their scholastic performances. Objective: To develop and standardize an inventory to assess the prakriti of the children, and to compare with Child Personality Questionnaire (CPQ). Materials and Methods: A 135-item Ayurveda child personality inventory (ACPI) scale was developed on the basis of translation of Sanskrit verses describing vataja (A), pittaja (B), and kaphaja prakriti (C) characteristics and by taking the opinions of experts (ten Ayurveda experts and three psychologists). Study was carried out in Maxwell public school, Bangalore. The scale was administered on parents of children of the age group 6-12 years. CPQ was administered on children of the age group 8-12 years. Results: The ACPI was associated with excellent internal consistency. The Cronbach's alpha for A, B, and C scales were 0.77, 0.55, and 0.84, respectively, and the Split-half reliability scores were 0.66.0.39 and 0.84, respectively. Factor validity coefficient scores on each items was above 0.5. Scores on vataja, pittaja and kaphaja scales were inversely correlated. Items of V, P, and K scales showed significant correlation (values ranging from 0.39 to 0.84) with subscales of CPQ, which indicates that Eastern and Western psychology concept have good correspondence. Conclusions: The prakrti of the children can be measured consistently by this instrument. Scores on V and P scale showed good correlation with the anxiety primary scale of CPQ. PMID:25624693

    The University Personality Inventory, a mental health instrument for college students, is frequently used for screening in China. However, its unidimensionality has been questioned. This study examined its dimensions to provide more information about the specific mental problems for students at risk. Four subsamples were randomly created from a sample (N = 6,110; M age = 19.1 yr.) of students at a university in China. Principal component analysis with Promax rotation was applied on the first two subsamples to explore dimension of the inventory. Confirmatory factor analysis was conducted on the third subsample to verify the exploratory dimensions. Finally, the identified factors were compared to the Symptom Checklist-90 (SCL-90) to support validity, and sex differences were examined, based on the fourth subsample. Five factors were identified: Physical Symptoms, Cognitive Symptoms, Emotional Vulnerability, Social Avoidance, and Interpersonal Sensitivity, accounting for 60.3% of the variance. All the five factors were significantly correlated with the SCL-90. Women scored significantly higher than men on Cognitive Symptoms and Interpersonal Sensitivity. PMID:25933045

    2011-03-01

    The Narcissistic Personality Inventory (NPI) is a widely used measure of narcissism. However, debates persist about its exact factor structure with researchers proposing solutions ranging from two to seven factors. The present research aimed to clarify the factor structure of the NPI and further illuminate its nomological network. Four studies provided support for a three-factor model consisting of the dimensions of Leadership/Authority, Grandiose Exhibitionism, and Entitlement/Exploitativeness. The Leadership/Authority dimension was generally linked to adaptive outcomes whereas the other two dimensions, particularly Entitlement/Exploitativeness, were generally linked to maladaptive outcomes. These results suggest that researchers interested in the psychological and behavioral outcomes associated with the NPI should examine correlates at the facet level. In light of the findings, we propose a hierarchical model for the structure of the NPI and provide researchers with a scoring scheme for this commonly used instrument. PMID:20876550

  2. Domains and facets: hierarchical personality assessment using the revised NEO personality inventory.

    PubMed

    Costa, P T; McCrae, R R

    1995-02-01

    Personality traits are organized hierarchically, with narrow, specific traits combining to define broad, global factors. The Revised NEO Personality Inventory (NEO-PI-R; Costa & McCrae, 1992c) assesses personality at both levels, with six specific facet scales in each of five broad domains. This article describes conceptual issues in specifying facets of a domain and reports evidence on the validity of NEO-PI-R facet scales. Facet analysis-the interpretation of a scale in terms of the specific facets with which it correlates-is illustrated using alternative measures of the five-factor model and occupational scales. Finally, the hierarchical interpretation of personality profiles is discussed. Interpretation on the domain level yields a rapid understanding of the individual interpretation of specific facet scales gives a more detailed assessment. PMID:16367732

    In the first study, we administered the 40-item Narcissistic Personality Inventory (NPI; Raskin & Terry, 1988) to 843 female and 843 male college students, most of whom were Euro-American, to comprehensively assess the NPI factor structure using confirmatory factor analysis. Initial exploratory common factor analyses (N = 724) revealed a 2-factor model (Leadership/Authority and Exhibitionism/Entitlement). Subsequently, we used confirmatory factor analysis in a separate sample (N = 724) to evaluate the Emmons (1987) 4-factor model, the Raskin and Terry (1988) 7-factor model, the Kubarych, Deary, and Austin (2004) 2- and 3-factor models, and our 2-factor model. Finally, we assessed construct validity by correlating the scale scores with the Five-factor model of personality in an independent sample (N = 238). The 2-factor models for the NPI we obtained in this study and by Kubarych et al. (2004) appeared to be the most parsimonious models, with both a good fit to the data and satisfactory internal consistency values; so they are recommended for use. However, additional NPI research is needed to rescale, modify, or omit several NPI items and develop gender-equivalent items. PMID:18925501

    2015-12-01

    This psychometric analysis of the Argentinean version of the Personality Assessment Inventory employed a convenience sample of 998 non-clinical adults from Buenos Aires, Argentina, stratified by sex and age (50% men; M age = 40.4 yr., SD = 16.8; 50% women; M age = 40.7 yr., SD = 17.4; 69% were employed). For a criterion validity study, a second sample of 394 students at the University of Buenos Aires was selected (47% men; M age = 24 yr., SD = 3.7; 53% women; M age = 23.6 yr., SD = 3.4). Cronbach's αs ranged from .60 to .86, indicating adequate internal consistency. Following American, German, and Spanish studies, a first analysis on the 22 scales obtained a five-factor solution (65.3% of total variance), and a second analysis on 11 clinical scales isolated a two-factor solution (69.3% of total variance). Correlations with the Symptom Checklist-90-R provided support for criterion validity. Most of the scales and subscales showed sex differences and differences between American and Argentinean samples. Future research must add other psychometric indicators. PMID:26595301

  6. A test of two brief measures of grandiose narcissism: the narcissistic personality inventory-13 and the narcissistic personality inventory-16.

    The most widely used measure of trait narcissism is the Narcissistic Personality Inventory (NPI), which can provide both total and subscale scores. However, with a length of 40 items, this measure may not be ideal in settings in which time or participant attention may limit the types of measures that can be administered. In response, Ames, Rose, and Anderson (2006) created the NPI-16, which provides a shorter, unidimensional measure of the construct. In the present research, we examine the reliability and validity of the NPI-16 in conjunction with a new short measure of narcissism, the NPI-13, which provides both a total score and 3 subscale scores (Leadership/Authority; Grandiose Exhibitionism; Entitlement/Exploitativeness). Across 2 studies, we demonstrate that both short measures manifest good convergent and discriminant validity and adequate overall reliability. The NPI-13 may be favored over the NPI-16 because it allows for the extraction of 3 subscales, consistent with the use of its parent measure. PMID:23815119

  7. Stability and change in personality assessment: the revised NEO Personality Inventory in the year 2000.

    PubMed

    Costa, P T; McCrae, R R

    1997-02-01

    The Revised NEO Personality Inventory (NEO-PI-R) consists of 30 facet scales that define the broad domains of the Five-Factor Model of personality. No major revisions of the basic model are anticipated in the near future. Despite their popularity, social desirability and inconsistency scales will not be added to the NEO-PI-R because their validity and utility have not yet been demonstrated. Among possible changes are minor modifications in wording and more extensive adaptations for adolescents and for populations with low reading levels. Contextualized (e.g., work-related) versions of the instrument will be further explored. Many changes are more easily implemented on the computer than the print version of the instrument.

  16. Personality and intentional binding: an exploratory study using the narcissistic personality inventory

    PubMed Central

    Hascalovitz, Ann (Chen); Obhi, Sukhvinder S.

    2015-01-01

    When an individual estimates the temporal interval between a voluntary action and a consequent effect, their estimates are shorter than the real duration. This perceived shortening has been termed “intentional binding”, and is often due to a shift in the perception of a voluntary action forward towards the effect and a shift in the perception of the effect back towards the action. Despite much work on binding, there is virtually no consideration of individual/personality differences and how they affect it. Narcissism is a psychological trait associated with an inflated sense of self, and individuals higher in levels of subclinical narcissism tend to see themselves as highly effective agents. Conversely, lower levels of narcissism may be associated with a reduced sense of agency. In this exploratory study, to assess whether individuals with different scores on a narcissism scale are associated with differences in intentional binding, we compared perceived times of actions and effects (tones) between participants with high, middle, and low scores on the narcissistic personality inventory (NPI). We hypothesized that participants with higher scores would show increased binding compared to participants with lower scores. We found that participants in our middle and high groups showed a similar degree of binding, which was significantly greater than the level of binding shown by participants with the lowest scores. To our knowledge, these results are the first to demonstrate that different scores on a personality scale are associated with changes in the phenomenological experience of action, and therefore underscore the importance of considering individual/personality differences in the study of volition. Our results also reinforce the notion that intentional binding is related to agency experience. PMID:25698952

    2015-10-01

    A considerable body of research has rapidly accumulated with respect to the validity of the Diagnostic and Statistical Manual of Mental Disorders (5th ed.; DSM-5) dimensional trait model as it is assessed by the Personality Inventory for Diagnostic and Statistical Manual of Mental Disorders (PID-5; Krueger et al., 2012). This research though has not focused specifically on discriminant validity, although allusions to potentially problematic discriminant validity have been raised. The current study addressed discriminant validity, reporting for the first time the correlations among the PID-5 domain scales. Also reported are the bivariate correlations of the 25 PID-5 maladaptive trait scales with the personality domain scales of the NEO Personality Inventory-Revised (Costa & McCrae, 1992), the International Personality Item Pool-NEO (Goldberg et al., 2006), the Inventory of Personal Characteristics (Almagor et al., 1995), the 5-Dimensional Personality Test (van Kampen, 2012), and the HEXACO Personality Inventory-Revised (Lee & Ashton, 2004). The results are discussed with respect to the implications of and alternative explanations for potentially problematic discriminant validity. (PsycINFO Database Record PMID:25894855

  3. Evaluating the Evidence for the General Factor of Personality across Multiple Inventories

    PubMed Central

    Hopwood, Christopher J.; Wright, Aidan G.C.; Donnellan, M. Brent

    2012-01-01

    A general factor of personality (GFP) has been proposed as the apex of a personality trait hierarchy that explains covariance among the lower-order factors measured by various personality inventories. In this study we evaluated the GFP hypothesis across several personality inventories, unlike most previous research in which the GFP has been derived from individual instruments in isolation. Exploratory analyses did not produce substantial evidence for the existence of a single cross-instrument higher-order factor of factors and efforts to specify a range of GFP-inspired models in a confirmatory framework led to significant estimation difficulties and poor fit to the data. Overall these results fail to support a common GFP that is positioned at the top of a personality trait hierarchy. PMID:22879686

    2002-01-01

    The authors addressed the culture specificity of indigenous personality constructs, the generalizability of the 5-factor model (FFM), and the incremental validity of indigenous measures in a collectivistic culture. Filipino college students (N = 508) completed 3 indigenous inventories and the Filipino version of the Revised NEO Personality Inventory (NEO-PI-R). On the basis of the factor and regression analyses, they concluded that (a) most Philippine dimensions are well encompassed by the FFM and thus may not be very culture specific: (b) a few indigenous constructs are less well accounted for by the FFM: these constructs are not unknown in Western cultures, but they may be particularly salient or composed somewhat differently in the Philippines; (c) the structure of the NEO-PI-R FFM replicates well in the Philippines: and (d) Philippine inventories add modest incremental validity beyond the FFM in predicting selected culture-relevant criteria.

    Conspiracy theories can be treated as both rational narratives of the world as well as outcomes of underlying maladaptive traits. Here, we examined associations between belief in conspiracy theories and individual differences in personality disorders. An Internet-based sample (N=259) completed measures of belief in conspiracy theories and the 25 facets of the Personality Inventory for DSM-5 (PID-5). Preliminary analyses showed no significant differences in belief in conspiracy theories across participant sex, ethnicity, and education. Regression analyses showed that the PID-5 facets of Unusual Beliefs and Experiences and, to a lesser extent, Suspiciousness, significantly predicted belief in conspiracy theories. These findings highlight a role for maladaptive personality traits in understanding belief in conspiracy theories, but require further investigation. PMID:26776299

    Although many clinical studies have been conducted to determine the etiological role and clinical implications of typus melancholicus for unipolar depression, maladaptive personality features in depressive patients have not been well described. This study explores typus melancholicus, as measured by the rigidity subscale of the Munich Personality Test, and maladaptive personality features, as measured by the Temperament and Character Inventory (TCI), in 131 remitted patients with DSM-IV major depression and 154 normal controls. The patients reported significantly higher scores on rigidity and harm avoidance and significantly lower scores on self-directedness and cooperativeness. Only 23.6% of the variance of the rigidity scale was explained by the variance of the seven TCI scales, in which only persistence was significantly correlated positively to rigidity. Cluster analysis identified four subgroups, two of which were characterized by a high rigidity score. One of these two subgroups showed no maladaptive personality features, as measured by the TCI, while the other showed high harm avoidance and low self-directedness. These results indicate that the personality of depressive patients is characterized not only by typus melancholicus but also by maladaptive personality features, that typus melancholicus is not well represented by any TCI scale, and that typus melancholicus and maladaptive personality features can coexist in some depressive patients.

  5. Development of a Response Inconsistency Scale for the Personality Inventory for DSM-5.

    PubMed

    Keeley, Jared W; Webb, Christopher; Peterson, Destiny; Roussin, Lindsey; Flanagan, Elizabeth H

    2016-01-01

    The advent of a dimensional model of personality disorder included in DSM-5 has necessitated the development of a new measurement scheme, specifically a self-report questionnaire termed the Personality Inventory for DSM-5 (PID-5; Krueger, Derringer, Markon, Watson, & Skodol, 2012 ). However, there are many threats to the validity of a self-report measure, including response inconsistency. This study outlines the development of an inconsistency scale for the PID-5. Across both college student and clinical samples, the inconsistency scale was able to reliably differentiate real from random responding. Random responses led to increased scores on the PID-5 facets, indicating the importance of detecting inconsistent responding prior to test interpretation. Thus, this inconsistency scale could be of use to researchers and clinicians in detecting inconsistent responses to this new personality disorder measure. PMID:27049169

    The factor structure and the convergent validity of the Personality Inventory for DSM-5 (PID-5), a self-report questionnaire designed to measure personality pathology as advocated in the fifth edition, Section III of Diagnostic and Statistical Manual of Mental Disorders (DSM-5), are already demonstrated in general population samples, but need replication in clinical samples. In 240 Flemish inpatients, we examined the factor structure of the PID-5 by means of exploratory structural equation modeling. Additionally, we investigated differences in PID-5 higher order domain scores according to gender, age and educational level, and explored convergent and discriminant validity by relating the PID-5 with the Dimensional Assessment of Personality Pathology-Basic Questionnaire and by comparing PID-5 scores of inpatients with and without a DSM-IV categorical personality disorder diagnosis. Our results confirmed the original five-factor structure of the PID-5. The reliability and the convergent and discriminant validity of the PID-5 proved to be adequate. Implications for future research are discussed. PMID:25736039

    The Triarchic model of psychopathy describes this complex condition in terms of distinct phenotypic components of boldness, meanness, and disinhibition. Brief self-report scales designed specifically to index these psychopathy facets have thus far demonstrated promising construct validity. The present study sought to develop and validate scales for assessing facets of the Triarchic model using items from a well-validated existing measure of psychopathy—the Psychopathic Personality Inventory (PPI). A consensus rating approach was used to identify PPI items relevant to each Triarchic facet, and the convergent and discriminant validity of the resulting PPI-based Triarchic scales were evaluated in relation to multiple criterion variables (i.e., other psychopathy inventories, antisocial personality disorder features, personality traits, psychosocial functioning) in offender and non-offender samples. The PPI-based Triarchic scales showed good internal consistency and related to criterion variables in ways consistent with predictions based on the Triarchic model. Findings are discussed in terms of implications for conceptualization and assessment of psychopathy. PMID:24447280

    Diagnostic and Statistical Manual of Mental Disorders (5th ed.; DSM-5) includes a dimensional model of personality pathology, operationalized in the Personality Inventory for DSM-5 (PID-5), with 25 facets grouped into 5 higher order factors resembling the Big Five personality dimensions. The present study tested how well these 25 facets could be integrated with the 10-factor structure of traits within the Big Five that is operationalized by the Big Five Aspect Scales (BFAS). In 2 healthy adult samples, 10-factor solutions largely confirmed our hypothesis that each of the 10 BFAS would be the highest loading BFAS on 1 and only 1 factor. Varying numbers of PID-5 scales were additional markers of each factor, and the overall factor structure in the first sample was well replicated in the second. Our results allow Cybernetic Big Five Theory (CB5T) to be brought to bear on manifestations of personality disorder, because CB5T offers mechanistic explanations of the 10 factors measured by the BFAS. Future research, therefore, may begin to test hypotheses derived from CB5T regarding the mechanisms that are dysfunctional in specific personality disorders. PMID:27032017

    1989-01-01

    The NEO Personality Inventory (NEO-PI) consists of 5 global domain and 18 specific facet scales developed to measure aspects of the five major dimensions of normal personality. To obtain optimal measures of these five dimensions from the NEO-PI scales, a method for the orthogonal rotation of principal components to maximize the convergent and discriminant validity of the rotated factors (validimax rotation) is proposed and applied to NEO-PI factors. Self-report data from 983 men and women were used to obtain the factors, and six alternative operationalizations of the five-factor model were used as external criteria to guide rotation. The rotation obtained was cross-validated on peer and spouse ratings on the NEO-PI, and in a second sample. NEO-PI domain scales, varimax factors, and validimax factors all showed evidence of construct validity, but validimax factors were somewhat superior, especially as measures of Agreeableness and Conscientiousness.

    This study sought to replicate and extend Hall and colleagues' (2014) work on developing and validating scales from the Psychopathic Personality Inventory (PPI) to index the triarchic psychopathy constructs of boldness, meanness, and disinhibition. This study also extended Hall et al.'s initial findings by including the PPI Revised (PPI-R). A community sample (n = 240) weighted toward subclinical psychopathy traits and a male prison sample (n = 160) were used for this study. Results indicated that PPI-Boldness, PPI-Meanness, and PPI-Disinhibition converged with other psychopathy, personality, and behavioral criteria in ways conceptually expected from the perspective of the triarchic psychopathy model, including showing very strong convergent and discriminant validity with their Triarchic Psychopathy Measure counterparts. These findings further enhance the utility of the PPI and PPI-R in measuring these constructs. PMID:25325407

    Personality Assessment Inventory (PAI) profiles were examined in 160 U.S. service members (SMs) following mild–severe traumatic brain injury (TBI). Participants who sustained a mild TBI had significantly higher PAI scores than those with moderate–severe TBI on eight of the nine clinical scales examined. A two-step cluster analysis identified four PAI profiles, heuristically labeled “High Distress”, “Moderate Distress”, “Somatic Distress,” and “No Distress”. Postconcussive and posttraumatic stress symptom severity was highest for the High Distress group, followed by the Somatic and Moderate Distress groups, and the No Distress group. Profile groups differed in age, ethnicity, rank, and TBI severity. Findings indicate that meaningful patterns of behavioral and personality characteristics can be detected in active duty military SMs following TBI, which may prove useful in selecting the most efficacious rehabilitation strategies.

    2011-04-01

    The Dark Triad of personality, comprising Machiavellianism, narcissism, and psychopathy, was investigated in relation to the Supernumerary Personality Inventory (SPI) traits, because both sets of variables are predominantly distinct from the Big Five model of personality. Correlational and principal factor analyses were conducted to assess the relations between the Dark Triad and SPI traits. Multivariate behavioral genetic model-fitting analyses were also conducted to determine the correlated genetic and/or environmental underpinnings of the observed phenotypic correlations. Participants were 358 monozygotic and 98 same-sex dizygotic adult twin pairs from North America. As predicted, results revealed significant correlations between the Dark Triad and most SPI traits, and these correlations were primarily attributable to common genetic and non-shared environmental factors, except in the case of Machiavellianism, where shared environmental effects emerged. Three correlated factors were extracted during joint factor analysis of the Dark Triad and SPI traits, as well as a heritable general factor of personality - results that clarified the structure of the Dark Triad construct. It is concluded that the Dark Triad represents an exploitative and antisocial construct that extends beyond the Big Five model and shares a theoretical space with the SPI traits. PMID:21425898

    Project Talent is a national longitudinal study that started in 1960. The original sample included over 440,000 students, which amounted to a 5% representative sample of high school students across the United States. Previous research has not yet established the validity and reliability of the personality measure used in this study, that is, the Project Talent Personality Inventory (PTPI). Given the potential interest and use of the PTPI in forthcoming research, the goals of the present paper were to establish (a) the construct and predictive validity and (b) the internal consistency and test-retest reliability of the PTPI. This information will be valuable to researchers who might be interested in using the PTPI to predict life course outcomes, such as mortality, occupational success, relationship success, and health. Study 1 found that the 10 sub-scales of the PTPI showed good internal consistency reliability, as well as good construct and predictive validity. With the use of several modern personality measures, we showed how the 10 PTPI scales can be mapped onto the Big Five personality traits, and we examined their relations with health, well-being, and life satisfaction outcomes. Study 2 found that the 10 PTPI scales showed good test-retest reliability. Together, these findings allow researchers to better understand and use the PTPI scales, as they are available in Project Talent. PMID:24399984

    2015-08-01

    Previous research has demonstrated RBS and FBS-r to identify non-credible reporters of cognitive symptoms, but the extent that these scales might be influenced by true neurocognitive dysfunction has not been previously studied. The present study examined the relationship between these cognitive validity scales and neurocognitive performance across seven domains of cognitive functioning, both before and after controlling for PVT status in 120 individuals referred for neuropsychological evaluations. Variance in RBS, but not FBS-r, was significantly accounted for by neurocognitive test performance across most cognitive domains. After controlling for PVT status, however, relationships between neurocognitive test performance and validity scales were no longer significant for RBS, and remained non-significant for FBS-r. Additionally, PVT failure accounted for a significant proportion of the variance in both RBS and FBS-r. Results support both the convergent and discriminant validity of RBS and FBS-r. As neither scale was impacted by true neurocognitive dysfunction, these findings provide further support for the use of RBS and FBS-r in neuropsychological evaluations. PMID:26051870

    Coldheartedness is a subscale of the Psychopathic Personality Inventory-Revised (PPI-R) that does not load onto either of the PPI-R's two traditional higher order factors (Fearless Dominance [FD] and Self-Centered Impulsivity [SCI]). As a result, it has been omitted from analyses in many studies. However, owing to Coldheartedness's associations with lack of empathy, guilt, and deep-seated social emotions, this subscale may be highly relevant to the construct of psychopathy. In a sample of 1,158 undergraduates, we attempted to clarify Coldheartedness's correlates within the context of a nomological network of psychopathology and personality; in addition, we examined Coldheartedness's contributions to psychopathy above and beyond FD and SCI. Coldheartedness demonstrated negative correlations with the Big Five personality factors, mixed correlations with indices of impulsivity, and largely negative correlations with measures of depression and anxiety. Regressions suggested that Coldheartedness displays substantial overlap with both FD and SCI but also contains psychologically important unique variance. Although the nature of this variance requires clarification, further research and perhaps an expansion of the Coldheartedness subscale may move the field toward a clearer understanding of the construct assessed by this measure.

    In the context of the publication of DSM-5, the Personality Inventory for DSM-5 (PID-5) has been proposed as a new dimensional assessment tool for personality disorders. This instrument includes a pool of 220 items organized around 25 facets included in a five-factor second-order domain structure. The examination of the replicability of the trait structure across methods and populations is of primary importance. In view of this need, the main objective of the current study was to validate the French version of the PID-5 among French-speaking adults from a European community sample (N=2,532). In particular, the assumption of unidimensionality of the 25 facet and the five domain scales was tested, as well as the extent to which the five-factor structure of the PID-5 and the DSM-5 personality trait hierarchical structure are replicated in the current sample. The results support the assumption of unidimensionality of both the facets and the domains. Exploratory factor and hierarchical analyses replicated the five-factor structure as initially proposed in the PID-5. PMID:26193699

    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

    Summary The University Personality Inventory, a mental health instrument for college students, is frequently used for screening in China. However, its unidimensionality has been questioned. This study examined its dimensions to provide more information about the specific mental problems for students at risk. Four subsamples were randomly created from a sample (N = 6,110; M age = 19.1 yr.) of students at a university in China. Principal component analysis with Promax rotation was applied on the first two subsamples to explore dimension of the inventory. Confirmatory factor analysis was conducted on the third subsample to verify the exploratory dimensions. Finally, the identified factors were compared to the Sympton Checklist–90 (SCL–90) to support validity, and sex differences were examined, based on the fourth subsample. Five factors were identified: Physical Symptoms, Cognitive Symptoms, Emotional Vulnerability, Social Avoidance, and Interpersonal Sensitivity, accounting for 60.3% of the variance. All the five factors were significantly correlated with the SCL–90. Women significantly scored higher than men on Cognitive Symptoms and Interpersonal Sensitivity. PMID:25933045

Descriptive results indicate that mean PAI full-scale and subscale scores are consistently lower than normative community sample scores, with some exceptions noted typically associated with defensive responding. Predictive validity was examined by relating PAI full-scale and subscale scores to supervisor ratings in the areas of job performance, integrity problems, and abuse of disability status. Modest correlations were observed for all domains; however, predictive validity was moderated by defensive response style, with greater predictive validity observed among less defensive responders. These results suggest that the PAI's full scales and subscales are able to predict law enforcement officers' performance, but their utility is appreciably improved when taken in the context of indicators of defensive responding.

    2011-09-01

    Research on the factor structure of psychopathy has yielded mixed results, supporting anywhere from one to three factors. Additionally, most of this research has used all-male samples, and the possibility of structural invariance across gender has not been examined. Using a mixed-gender sample of 360 undergraduates, the factor structure of the Psychopathic Personality Inventory-Revised was examined using confirmatory factor analysis and multiple group analysis. One-, two-, and three-factor models were tested and compared with each other. When males and females were combined, none of the three models provided adequate fit to the data. Multiple group analyses revealed partial invariance across gender for all three models. Model comparison criteria supported use of both the one- and two-factor models, taking into account variable factor structure across gender. The importance of considering structural differences based on biological sex when assessing psychopathic traits is discussed. PMID:21490056

    The purpose of this study was to characterize the operating characteristics of the Personality Assessment Inventory (PAI) validity scales in distinguishing simulators feigning symptoms of traumatic brain injury (TBI) while completing the PAI (n = 84) from a clinical sample of patients with TBI who achieved adequate scores on performance validity tests (n = 112). The simulators were divided into two groups: (a) Specific Simulators feigning cognitive and somatic symptoms only or (b) Global Simulators feigning cognitive, somatic, and psychiatric symptoms. The PAI overreporting scales were indeed sensitive to the simulation of TBI symptoms in this analogue design. However, these scales were less sensitive to the feigning of somatic and cognitive TBI symptoms than the feigning of a broad range of cognitive, somatic, and emotional symptoms often associated with TBI. The relationships of TBI simulation to consistency and underreporting scales are also explored. PMID:24965838

    Objectives Our objective was to examine the Beck Depression Inventory-II (BDI-II) in a traumatic brain injury (TBI) sample using a receiver operating characteristic (ROC) curve to determine how well the BDI-II identifies depression. An ROC curve allows for analysis of the sensitivity and specificity of a diagnostic test using various cutoff points to determine the number of true positives, true negatives, false positives, and false negatives. Design This was a secondary analysis of data gathered from an observational study. We examined BDI-II scores in a sample of 52 veterans with remote histories of TBI. Setting This study was completed at a Veterans Affairs (VA) Medical Center. Participants Participants were veterans eligible to receive VA health care services. Interventions Not applicable. Main Outcome Measures Outcome measures included the BDI-II and the Structured Clinical Interview for DSM-IV Axis I Disorders (SCID-IV). Results We generated an ROC curve to determine how well the BDI-II identifies depression using the SCID-IV as the criterion standard for diagnosing depression, defined here as a diagnosis of major depressive disorder. Results indicated a cutoff score of at least 19 if one has a mild TBI or at least 35 if one has a moderate or severe TBI. These scores maximize sensitivity (87%) and specificity (79%). Conclusions Clinicians working with persons with TBI can use the BDI-II to determine whether depressive symptoms warrant further assessment. PMID:19345782

    Davidson, Megan; Sorensen, Jon R; Reidy, Thomas J

    2016-02-01

    Proper inmate assessment is critical to correctional management and institutional security. While many instruments have been developed to assist with this process, most of these tools have not been validated using samples of female inmates although distinct gender differences have been identified in the inmate population in terms of adaptation and misconduct. The Personality Assessment Inventory (PAI) is a multiscale measure of psychopathology that is being increasingly utilized in the correctional setting to assist with the inmate classification process. The current study contributes to the dearth of literature surrounding gender-responsive inmate classification by utilizing a sample of 2,000 female inmates to examine the incremental and predictive validity of the PAI in association with general and assaultive disciplinary infractions. Findings from this study reveal that the PAI scales presenting the strongest relationship to general and assaultive disciplinary infractions among this female sample included Aggression (AGG), Antisocial Features (ANT), Paranoia (PAR), and the Violence Potential Index (VPI). Moreover, findings derived from this study suggest that certain PAI measures, specifically ARD-T, DRU, and more general substance abuse and mental health indicators may be useful in gender-responsive assessments during the female inmate classification process.

  8. Personality Assessment Inventory scores as predictors of misconduct, recidivism, and violence: A meta-analytic review.

    PubMed

    Gardner, Brett O; Boccaccini, Marcus T; Bitting, Brian S; Edens, John F

    2015-06-01

    More than 30 studies have examined the ability of scores on the Personality Assessment Inventory (PAI; Morey, 1991, 2007) to predict violence or misconduct. The Antisocial Features (ANT), Aggression (AGG), and Violence Potential Index (VPI) Scales of the PAI, in particular, have received substantial attention as predictors of institutional infractions and criminal recidivism. The current study used meta-analysis to provide a comprehensive review of the ability of scores on these and other PAI scales to predict misbehavior. Scores on the ANT (d = .26 to .39) and AGG (d = .23 to .40) scales consistently emerged as small to moderate predictors of misbehavior. Effects tended to be larger in correctional than treatment settings (e.g., ANT d = .44 vs. .20), for institutional misconduct than recidivism (e.g., AGG d = .37 vs. .23), and for institutional misconduct studies with follow up periods of at least 1.5 years (e.g., ANT d = .46). Overall, findings provide support for the predictive validity of multiple PAI scales. PMID:25528162

The FFI-BPD values for Sample 3 in Table 2 should read 1.42 (0.44), 0.83.] The aim of the current study was to examine the reliability and validity of a trait-based assessment of borderline personality disorder (BPD) using the NEO Five-Factor Inventory. Correlations between the Five-Factor Inventory-BPD composite (FFI-BPD) and explicit measures of BPD were examined across 6 samples, including undergraduate, community, and clinical samples. The median correlation was .60, which was nearly identical to the correlation between measures of BPD and a BPD composite generated from the full Revised NEO Personality Inventory (i.e., NEO-BPD; r = .61). Correlations between FFI-BPD and relevant measures of psychiatric symptomatology and etiology (e.g., childhood abuse, drug use, depression, and personality disorders) were also examined and compared to those generated using explicit measures of BPD and NEO-BPD. As expected, the FFI-BPD composite correlated most strongly with measures associated with high levels of Neuroticism, such as depression, anxiety, and emotion dysregulation, and the pattern of correlations generated using the FFI-BPD was highly similar to those generated using explicit measures of BPD and NEO-BPD. Finally, genetic analyses estimated that FFI-BPD is 44% heritable, which is comparable to meta-analytic research examining genetics associated with BPD, and revealed that 71% of the genetic influences are shared between FFI-BPD and a self-report measure assessing BPD (Personality Assessment Inventory-Borderline subscale; Morey, 1991). Generally, these results support the use of FFI-BPD as a reasonable proxy for BPD, which has considerable implications, particularly for potential gene-finding efforts in large, epidemiological datasets that include the NEO FFI.

    We present the development and the underlying structure of a personality inventory for the main ethnocultural groups of South Africa, using an emic-etic approach. The South African Personality Inventory (SAPI) was developed based on an extensive qualitative study of the implicit personality conceptions in the country's 11 official languages (Nel et al., 2012). Items were generated and selected (to a final set of 146) with a continuous focus on cultural adequacy and translatability. Students and community adults (671 Blacks, 198 Coloreds, 104 Indians, and 391 Whites) completed the inventory. A 6-dimensional structure (comprising a positive and a negative Social-Relational factor, Neuroticism, Extraversion, Conscientiousness, and Openness) was equivalent across groups and replicated in an independent sample of 139 Black and 270 White students. The SAPI correlated highly overall with impression-management aspects, but lower with lying aspects of social desirability. The SAPI social-relational factors were distinguishable from the Big Five in a joint factor analysis; the multiple correlations with the Big Five were .64 (positive) and .51 (negative social-relational). Implications and suggestions for emic-etic instrument and model development are discussed. PMID:25602691

    Posttraumatic stress disorder (PTSD) is associated with aggressive behavior in veterans, and difficulty controlling aggressive urges has been identified as a primary postdeployment readjustment concern. Yet only a fraction of veterans with PTSD commit violent acts. The goals of this study were to (1) examine the higher-order factor structure of Personality Assessment Inventory (PAI) scales in a sample of U.S. military veterans seeking treatment for PTSD; and (2) to evaluate the incremental validity of higher-order latent factors of the PAI over PTSD symptom severity in modeling aggression. The study sample included male U.S. Vietnam (n = 433) and Iraq/Afghanistan (n = 165) veterans who were seeking treatment for PTSD at an outpatient Veterans Affairs (VA) clinic. Measures included the Clinician Administered PTSD Scale, the PAI, and the Conflict Tactics Scale. The sample was randomly split into two equal subsamples (n’s = 299) to allow for cross-validation of statistically derived factors. Parallel analysis, variable clustering analysis, and confirmatory factor analyses were used to evaluate the factor structure, and regression was used to examine the association of factor scores with self-reports of aggression over the past year. Three factors were identified: internalizing, externalizing, and substance abuse. Externalizing explained unique variance in aggression beyond PTSD symptom severity and demographic factors, while internalizing and substance abuse did not. Service era was unrelated to reports of aggression. The constructs of internalizing versus externalizing dimensions of PTSD may have utility in identifying characteristics of combat veterans in the greatest need of treatment to help manage aggressive urges.

    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

    In science, multiple measures of the same constructs can be useful, but they are unlikely to all be equally valid indicators. In psychological assessment, the many popular personality inventories available in the marketplace also may be useful, but their comparative validity has long remained unassessed. This is the first comprehensive comparison of 11 such multiscale instruments against each of three types of criteria: clusters of behavioral acts, descriptions by knowledgeable informants, and clinical indicators potentially associated with various types of psychopathology. Using 1,000 bootstrap resampling analyses from a sample of roughly 700 adult research participants, we assess the relative predictability of each criterion and the comparative validity of each inventory. Although there was a wide range of criterion predictability, most inventories exhibited quite similar cross-validities when averaged across all three types of criteria. On the other hand, there were important differences between inventories in their predictive capabilities for particular criteria. We discuss the factors that lead to differential validity across predictors and criteria. PMID:17764394

    The aim of the present study is to determine the validity and reliability of the French version of the PSI-II. The PSI-II is a self-rating scale divided into two subscales containing each 24 items and rating sociotropy and autonomy. 202 university students (170 females, 32 males) with a mean age of 21.54 years (sd = 4.16) were included. They filled out the PSI-II and the Interpersonal Dependency Inventory (IDI). The construct validity was explored using an exploratory principal components analysis followed by an orthogonal varimax rotation. The results had shown a three-factor solution with a "sociotropy" factor and two "autonomy" factors. The Cronbach alpha coefficients were respectively 0.83 and 0.72 for the sociotropy and autonomy subscales. The Pearson correlations between the PSI-II and IDI subscales showed significant correlation first between the sociotropy subscale and the two subscales of the IDI rating dependency, the values were respectively 0.67 (p < 0.001) and 0.44 (p < 0.001), and secondly between the autonomy subscales of the PSI-II and IDI, the value was 0.39 (p < 0.001). The sociotropy subscale items correlated significantly with the total score of the subscale with a mean of 0.46. 23 items of the autonomy subscale correlated with the total score with a mean of 0.36. The sociotropy and autonomy scores were respectively 93.98 (sd = 14.22) and 84.55 (sd = 11.69). The French version of the PSI-II had satisfactory metrological parameters and allows to study sociotropy and autonomy in French population. PMID:9559301

    The Schedule for Nonadaptive and Adaptive Personality-Youth Version (SNAP-Y) is a new, reliable self-report questionnaire that assesses 15 personality traits relevant to both normal-range personality and the alternative DSM-5 model for personality disorder. Community adolescents, 12 to 18 years old (N = 364), completed the SNAP-Y; 347 also completed the Big Five Inventory-Adolescent, 144 provided 2-week retest data, and 128 others completed the Minnesota Multiphasic Personality Inventory-Adolescent. Outpatient adolescents (N = 103) completed the SNAP-Y, and 97 also completed the Minnesota Multiphasic Personality Inventory-Adolescent. The SNAP-Y demonstrated strong psychometric properties, and structural, convergent, discriminant, and external validities. Consistent with the continuity of personality, results paralleled those in adult and college samples using the adult Schedule for Nonadaptive and Adaptive Personality-Second Edition (SNAP-2), from which the SNAP-Y derives and which has established validity in personality-trait assessment across the normal-abnormal continuum. The SNAP-Y thus provides a new, clinically useful instrument to assess personality traits and personality pathology in adolescents. PMID:23794180

    Eating competence is an important behavioral construct, shown to be associated with healthful lifestyle practices, including dietary quality, weight management, physical activity, and sleep duration. A 16-item instrument to measure eating competence, the Satter Eating Competence Inventory was previously validated in a general sample and subsequently, a 16-item instrument was developed to address specific concerns of low-income persons; 12 items were common to both instruments. The purpose of this study was to determine if the low-income version could be applied to a general audience, simplifying intervention evaluation and facilitating cross-study comparison. Both surveys were fully completed by 127 parents (89% white; 35.8 ± 5.3 y; 86% college graduates; 51% eating competent) of preschool-age children; 96 of whom were not considered low-income. Cognitive interviews with 14 parents of varying eating competence levels clarified and confirmed findings. Scores were highly correlated (r = .98) and only 2 of the 96 were not congruently classified for eating competence. Mean difference between the two versions was .24 ± 1.55. The general audience version explained 95% of the variance in the low-income version score. Findings support the low-income version of the Satter Eating Competence Inventory for general audience use as the Satter Eating Competence Inventory 2.0. PMID:25558022

    INTRODUCTION: Multiple factors of vulnerability may lead to development of abnormal social behaviour and to important psychiatric diseases. The psychopathological characteristics present at individual level can lead to a pattern of population groups that are subject to developing mental illness risks. MATERIAL AND METHODS: Multidisciplinary study (2009-2011) to assessing the current situation of mental health and identifying population risk groups for developing psychiatric disorders in a non-institutionalised population. We used the Woodworth Mathews Inventory (76 items) to a randomly selected sample of 1,200 men and women, residents in urban and rural areas. RESULTS: The extreme scores for emotiveness had a frequency more than triple for women, and we found a similar situation for obsessive-neurasthenic and depressive tendencies. People aging over 35 years had a double score (limit and poignancy) for depression than younger people, meanwhile correlation between age under 35 years and instability and antisocial tendencies is highly statistically significant (p<0.001), the frequency of extreme scores being almost double than in the older people. CONCLUSIONS: Female gender has a vulnerability for develop depressive and emotional disorders and age over 35 is also significant correlated with depressive tendencies. Younger people (under 35 years) are predisposed for pathological antisocial behaviour, fact revealed by the high scores for instability and antisocial tendencies. It is necessary to develop a program focused on the two risk categories to prevent the possible occurrence of psychiatric disorders. PMID:25729602

    There are a number of prominent trait-based models and assessments of psychopathy that posit the existence of a varying number of central traits, which differ in their relation to one another and the degree to which they manifest similar empirical networks. In the current study (N = 347), we examined Lilienfeld's popular 3-factor model and measure (Psychopathic Personality Inventory-Short Form; Kastner, Sellbom, & Lilienfeld, 2012; Lilienfeld & Andrews, 1996) in relation to adverse developmental factors, self and informant ratings of general personality and "near neighbor" personality styles from the Dark Triad (e.g., narcissism), as well as internalizing symptoms and externalizing behaviors. The 3 factors-Fearless Dominance, Self-centered Impulsivity, and Coldheartedness-manifested relatively limited relations with one another (median r = .22) and demonstrated varying empirical networks such that Self-centered Impulsivity was associated with substantial maladaptivity, Fearless Dominance was associated with a mixture of adaptive and maladaptive correlates, and Coldheartedness' relations to the external criteria fell in between and manifested a relatively small number of significant correlations. There was little evidence that the psychopathy factors in general, and Fearless Dominance more specifically, interacted with one another in the prediction of externalizing behaviors or interacted with adverse developmental/parental experiences to predict these behaviors. These results are relevant to ongoing discussions regarding the manner in which psychopathy is conceptualized and assessed. (PsycINFO Database Record PMID:26348030

    2013-01-01

    The Externalizing Spectrum Inventory (ESI; Krueger, Markon, Patrick, Benning, & Kramer, 2007) provides a self-report based method for indexing a range of correlated problem behaviors and traits in the domain of deficient impulse control. The ESI organizes lower-order behaviors and traits of this kind around higher-order factors encompassing general disinhibitory proneness, callous-aggression, and substance abuse. The current study used data from a male prisoner sample (N = 235) to evaluate the validity of ESI total and factor scores in relation to external criterion measures consisting of externalizing disorder symptoms (including child and adult antisocial deviance and substance-related problems) assessed via diagnostic interview, personality traits assessed by self-report, and psychopathic features as assessed by both interview and self-report. Results provide evidence for the validity of the ESI measurement model and point to its potential utility as a referent for research on the neurobiological correlates and etiological bases of externalizing proneness.

    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

    2015-12-15

    Studies have found relationships between dream content and personality traits, but there are still many traits that have been underexplored or have had questionable conclusions drawn about them. Experimental work has found a 'rebound' effect in dreams when thoughts are suppressed prior to sleep, but the effect of trait thought suppression on dream content has not yet been researched. In the present study participants (N=106) reported their Most Recent Dream, answered questions about the content of the dream, and completed questionnaires measuring trait thought suppression and the 'Big Five' personality traits. Of these, 83 were suitably recent for analyses. A significant positive correlation was found between trait thought suppression and participants' ratings of dreaming of waking-life emotions, and high suppressors reported dreaming more of their waking-life emotions than low suppressors did. The results may lend support to the compensation theory of dreams, and/or the ironic process theory of mental control. PMID:26496477

    Although professional surveys suggest that the Personality Assessment Inventory (PAI; Morey, 1991) is a popular instrument among forensic and correctional psychologists, relatively little is known about the specific types of legal cases in which it is applied, the particular types of questions it is used to address, or the extent to which its admissibility has been at issue in court cases. Using a comprehensive legal database, we surveyed all published U.S., Canadian, European, and Australian criminal and civil cases in which the PAI was administered. The PAI appears to be introduced by examiners in a wide variety of civil (e.g., child custody, personal injury) and criminal (e.g., insanity, competence) cases to aid in the assessment of a broad range of psychopathology. Additionally, the PAI seems to be used frequently to assess questions concerning potential dissimulation and response styles. Surprisingly, the admissibility of the PAI into evidence was never at issue in any of the cases reviewed. PMID:18444127

    This study used the Bear-Fedio Personality Inventory (BFI) to compare 41 individuals with temporal lobe epilepsy (TLE) and 37 with psychogenic non-epileptic seizures (NES). Both groups exhibited similar elevations on the BFI, although TLE individuals show greater endorsement of at least one hypergraphia symptom, as compared with those with NES. The correlates of the BFI with demographic and seizure characteristics differed between the groups. These results argue against a specific TLE personality syndrome and suggest that personality characteristics may be related to the experience of having repeated seizures, rather than the specific underlying pathophysiology of temporal lobe epilepsy.

    In order to evaluate if measures of DSM-5 Alternative PD Model domains predicted interview-based scores of general personality pathology when compared to self-report measures of DSM-IV Axis II/DSM-5 Section II PD criteria, 300 Italian community adults were administered the Iowa Personality Disorder Screen (IPDS) interview, the Personality Inventory for DSM-5 (PID-5), and the Personality Diagnostic Questionnaire-4+ (PDQ-4+). Multiple regression analyses showed that the five PID-5 domain scales collectively explained an adequate rate of the variance of the IPDS interview total score. This result was slightly lower than the amount of variance in the IPDS total score explained by the 10 PDQ-4+ scales. The PID-5 traits scales performed better than the PDQ-4+, although the difference was marginal. Hierarchical regression analyses revealed that the PID-5 domain and trait scales provided a moderate, but significant increase in the prediction of the general level of personality pathology above and beyond the PDQ-4+ scales.

    A wealth of research has underscored the strong relationship between PCL-R scores and recidivism. However, mounting criticism cites the PCL-R's cumbersome administration procedures and failure to adequately measure core features associated with the construct of psychopathy (Skeem, Polaschek, Patrick, & Lilienfeld, 2011). In light of these concerns, this study examined the PPI and the PPI-R, which were designed to measure core personality features associated with psychopathy (Lilienfeld & Andrews, 1996; Lilienfeld & Widows, 2005). Study one examined the PPI relative to the PCL-R and examined its factor structure. The instruments shared few significant correlations and neither the PCL-R nor the PPI significantly predicted recidivism. Study two examined the PPI-R relative to the PCL-R, the PPI, both history of violence and future criminal activity and measure of related constructs. The PPI-R was significantly correlated with measures of empathy and criminal thinking and the factors were related to a history of violence and predicted future violent criminal behavior.

    2016-08-01

    The Personality Assessment Inventory (PAI) has been widely employed in correctional settings as a screening tool to assess inmates' risk for committing various types of institutional misconduct. Evaluations have generally found the PAI scales Antisocial Features (ANT), Aggression (AGG), and the Violence Potential Index (VPI) to be modestly related to institutional misbehavior, thus supporting its construct validity. The current study provides the most comprehensive examination of the predictive and incremental validity of the PAI and its subscales among a large sample of imprisoned offenders to date. In particular, the size of the sample (n = 15,546) and follow-up period (mean time at risk of 2.2 years) allowed for the disaggregation of institutional misconduct by levels of seriousness and separate examinations by conviction offense and criminal history variables. The 3 scales most strongly related to general rule infractions were ANT, AGG, and the VPI. After controlling for age at intake, violent conviction history, prior violent arrests, and time at risk, the PAI scales were shown to add incremental validity to the classification of 4 types of disciplinary infractions ranging from 2 to 4 percentage points. The study also explored the relationship of the PAI's response bias scales to institutional misconduct. (PsycINFO Database Record PMID:26460899

    2004-09-01

    This study is an investigation of the Sternberg-Wagner Thinking Style Inventory (TSI), with regard to cross-cultural replication and relation to the five-factor personality model (FFM). TSI and NEO-PI-R were administered to 107 participants from USA and 114 participants from Norway. Inter-correlations between NEO-PI-R dimensions and TSI-scales and factors were not very strong, few exceeding 0.40, and the correlations were in predicted directions. Joint factor analyses of TSI and NEO-PI-R showed that TSI covers variance that NEO-PI-R does not explain. Thus, it is argued that the thinking styles give an independent contribution beyond FFM dimensions. However, TSI did not relate to FFM in the same manner in the two samples. Finally, the TSI-scales and factors were replicable across samples by Procrustes rotation. The question whether thinking style may be regarded as a valid and reliable construct is discussed.

    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

    Mega- or meta-analytic studies (e.g. genome-wide association studies) are increasingly used in behavior genetics. An issue in such studies is that phenotypes are often measured by different instruments across study cohorts, requiring harmonization of measures so that more powerful fixed effect meta-analyses can be employed. Within the Genetics of Personality Consortium, we demonstrate for two clinically relevant personality traits, Neuroticism and Extraversion, how Item-Response Theory (IRT) can be applied to map item data from different inventories to the same underlying constructs. Personality item data were analyzed in >160,000 individuals from 23 cohorts across Europe, USA and Australia in which Neuroticism and Extraversion were assessed by nine different personality inventories. Results showed that harmonization was very successful for most personality inventories and moderately successful for some. Neuroticism and Extraversion inventories were largely measurement invariant across cohorts, in particular when comparing cohorts from countries where the same language is spoken. The IRT-based scores for Neuroticism and Extraversion were heritable (48 and 49 %, respectively, based on a meta-analysis of six twin cohorts, total N = 29,496 and 29,501 twin pairs, respectively) with a significant part of the heritability due to non-additive genetic factors. For Extraversion, these genetic factors qualitatively differ across sexes. We showed that our IRT method can lead to a large increase in sample size and therefore statistical power. The IRT approach may be applied to any mega- or meta-analytic study in which item-based behavioral measures need to be harmonized. PMID:24828478

    One hundred and thirty-three paturients who had received either methoxyflurane-nitrous oxide or nitrous oxide analgesia with or without pudendal block, underwent the Eysenck Personality Inventory Test on the second postpartum day and evaluated their memory of the pain (Subjectively Evaluated Pain Suffering Scores) during labor. Parturients who had received methoxyflurance-nitrous oxide analgesia reported significantly lower pain suffering than parturients who had had nitrous oxide analgesia. Subdivision according to Personality Inventory factors showed that at the introvert end of the Extroversion-Introversion scale, methoxyflurance-nitrous oxide analgesia with or without additional pudendal block resulted in significantly lower pain suffering than did not nitrous oxide analgesia. On the other hand, nitrous oxide analgesia without additional pudendal block gave significantly lower pain suffering at the extrovert end of the scale. Among the extroverts there was a tendency, though not statistically significant, towards non-approval of the pudendal block. PMID:7424496

    In recent years, there has been an increasing interest in juvenile sex offenders showing that this population is highly heterogeneous. The aim of the present study was to identify possible different profiles that could help understand the motivation behind offending, comparing 31 Juvenile Sexual Offenders (JSOs), 31 Juvenile Sexual Non Offenders (JSNOs) and 31 Juvenile Non Offenders (Control Group). A data collection form, the Minnesota Multiphasic Personality Inventory-Adolescent (MMPI-A) or Minnesota Multiphasic Personality Inventory-2 (MMPI-2), the Coping Inventory for Stressful Situations (CISS) and the Parental Bonding Inventory (PBI) were administered to all participants. The results show that JSOs differs from JNSOs in some domains, such as living in single-parent homes, while maintain some common aspects such as academic failure and previous sexual intercourse. Moreover, JNSOs showed more abnormal personality traits, such as Authority Problems, MacAndrew Alcoholism, Acknowledgement and Alcohol-Drug Problem Proneness compared to JSOs and the Control Group, while JSOs and JNSOs use a coping strategy more oriented to Avoidance and Distraction compared to the Control group. Finally, JSOs described the relationships with fathers characterized by higher care and protection than JNSOs. These findings provide additional evidence with respect the prevention and treatment of criminal sexual behavior in adolescent. PMID:26233829

    Measurements and predictions of the structure of several multiphase flows are considered. The properties of dense sprays near the exits of pressure-atomizing injectors and of noncombusting and combusting dilute dispersed flows in round-jet configurations are addressed. It is found that the properties of dense sprays exhibit structure and mixing properties similar to variable-density single-phase flows at high Reynolds numbers within the atomization regime. The degree of development and turbulence levels at the injector exit have a surprisingly large effect on the structure and mixing properties of pressure-atomized sprays, particularly when the phase densities are large. Contemporary stochastic analysis of dilute multiphase flows provides encouraging predictions of turbulent dispersion for a wide variety of jetlike flows, particle-laden jets in gases and liquids, noncondensing and condensing bubbly jets, and nonevaporating, evaporating, and combusting sprays.

    Multiphase health screening procedures are advocated for detection and prevention of disease at an early stage through risk factor analysis. The use of an automated medical history questionnaire together with scheduled physical examination data provides a scanning input for computer printout. This system makes it possible to process laboratory results from 1,000 to 2,000 patients for biochemical determinations on an economically feasible base.

    The present pilot study is part of an ongoing effort to further the investigation of the relationship between spinal patterns and personality. The present pilot study seeks to identify likely spinal patterns of certain personality profiles and asks whether changing posture can affect personality, and/or can emotional states alter posture? Forty patients of a private chiropractic practice participated in the study. Four radiographs (x-rays) of each subject were taken and each subject completed the Minnesota Multiphasic Personality Inventory (MMPI). Measurements obtained from the radiographs and the MMPI data were used to derive general linear models of the predictability of the MMPI in terms of the spinal/postural measures. Several models were highly significant and preliminary support for the authors' hypothesis that spinal patterns are likely to be predictive of personality profiles is suggested. Support for previous research is offered and directions for future research are discussed. PMID:1428613

    The Narcissistic Personality Inventory (NPI) is currently the most widely used measure of narcissism in social/personality psychology. It is also relatively unique because it uses a forced-choice response format. We investigate the consequences of changing the NPI's response format for item meaning and factor structure. Participants were randomly assigned to one of three conditions: 40 forced-choice items (n = 2,754), 80 single-stimulus dichotomous items (i.e., separate true/false responses for each item; n = 2,275), or 80 single-stimulus rating scale items (i.e., 5-point Likert-type response scales for each item; n = 2,156). Analyses suggested that the "narcissistic" and "nonnarcissistic" response options from the Entitlement and Superiority subscales refer to independent personality dimensions rather than high and low levels of the same attribute. In addition, factor analyses revealed that although the Leadership dimension was evident across formats, dimensions with entitlement and superiority were not as robust. Implications for continued use of the NPI are discussed. PMID:25616401

    The Minnesota Multiphasic Personality Inventory-2-Restructured Form (Ben-Porath & Tellegen, 2008 ) Restructured Clinical scales and Higher Order scales were linked to the Millon Clinical Multiaxial Inventory-III (Millon, Millon, Davis, & Grossman, 2009 ) personality disorder scales and clinical syndrome scales in a Flemish/Dutch sample of psychiatric inpatients and outpatients, substance abuse patients, correctional inmates, and forensic psychiatric patients (N = 968). Structural validity of psychopathology and personality disorders as conceptualized by both instruments was investigated by means of principal component analysis. Results reveal a higher order structure with 4 dimensions (internalizing disorders, externalizing disorders, paranoid ideation/thought disturbance, and pathological introversion) that parallels earlier research on pathological personality dimensions as well as research linking pathological personality traits with mental disorders. Theoretical and clinical implications are considered. PMID:22338624

    The fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) includes an alternative model of personality disorders (PDs) in Section III, consisting in part of a pathological personality trait model. To date, the 220-item Personality Inventory for DSM-5 (PID-5; Krueger, Derringer, Markon, Watson, & Skodol, 2012) is the only extant self-report instrument explicitly developed to measure this pathological trait model. The present study used item response theory-based analyses in a large sample (n = 1,417) to investigate whether a reduced set of 100 items could be identified from the PID-5 that could measure the 25 traits and 5 domains. This reduced set of PID-5 items was then tested in a community sample of adults currently receiving psychological treatment (n = 109). Across a wide range of criterion variables including NEO PI-R domains and facets, DSM-5 Section II PD scores, and externalizing and internalizing outcomes, the correlational profiles of the original and reduced versions of the PID-5 were nearly identical (rICC = .995). These results provide strong support for the hypothesis that an abbreviated set of PID-5 items can be used to reliably, validly, and efficiently assess these personality disorder traits. The ability to assess the DSM-5 Section III traits using only 100 items has important implications in that it suggests these traits could still be measured in settings in which assessment-related resources (e.g., time, compensation) are limited.

    A measurement system and method for permitting multiple independent measurements of several physical parameters of multiphase fluids flowing through pipes are described. Multiple acoustic transducers are placed in acoustic communication with or attached to the outside surface of a section of existing spool (metal pipe), typically less than 3 feet in length, for noninvasive measurements. Sound speed, sound attenuation, fluid density, fluid flow, container wall resonance characteristics, and Doppler measurements for gas volume fraction may be measured simultaneously by the system. Temperature measurements are made using a temperature sensor for oil-cut correction.

    Tourette syndrome is a neurodevelopmental disorder characterized by multiple tics and commonly associated with behavioral problems, especially obsessive-compulsive disorder and attention-deficit hyperactivity disorder (ADHD). The presence of specific personality traits has been documented in adult clinical populations with Tourette syndrome but has been underresearched in younger patients. We assessed the personality profiles of 17 male adolescents with Tourette syndrome and 51 age- and gender-matched healthy controls using the Minnesota Multiphasic Personality Inventory-Adolescent version, along with a standardized psychometric battery. All participants scored within the normal range across all Minnesota Multiphasic Personality Inventory-Adolescent version scales. Patients with Tourette syndrome scored significantly higher than healthy controls on the Obsessiveness Content Scale only (P = .046). Our findings indicate that younger male patients with Tourette syndrome do not report abnormal personality traits and have similar personality profiles to healthy peers, with the exception of obsessionality traits, which are likely to be related to the presence of comorbid obsessive compulsive symptoms rather than tics.

    The 44-item and 10-item Big Five Inventory (BFI) personality scales are widely used, but there is a lack of psychometric data for Chinese versions. Eight surveys (total N = 2,496, aged 18-82), assessed a Chinese-language BFI-44 and/or an independently translated Chinese-language BFI-10. Most BFI-44 items loaded strongly or predominantly on the expected dimension, and values of Cronbach's alpha ranged .698-.807. Test-retest coefficients ranged .694-.770 (BFI-44), and .515-.873 (BFI-10). The BFI-44 and BFI-10 showed good convergent and discriminant correlations, and expected associations with gender (females higher for agreeableness and neuroticism), and age (older age associated with more conscientiousness and agreeableness, and also less neuroticism and openness). Additionally, predicted correlations were found with chronotype (morningness positive with conscientiousness), mindfulness (negative with neuroticism, positive with conscientiousness), and mind wandering/daydreaming frequency (negative with conscientiousness, positive with neuroticism). Exploratory analysis found that the Self-discipline facet of conscientiousness positively correlated with morningness and mindfulness, and negatively correlated with mind wandering/daydreaming frequency. Furthermore, Self-discipline was found to be a mediator in the relationships between chronotype and mindfulness, and chronotype and mind wandering/daydreaming frequency. Overall, the results support the utility of the BFI-44 and BFI-10 for Chinese-language big five personality research. PMID:26918618

    There is relatively little research on the Personality Assessment Inventory (PAI) with mild traumatic brain injury (MTBI) populations. There is also little research on how compensation-seeking status affects personality assessment results in MTBI patients. The current study examined the PAI scales and subscales in two MTBI groups, one composed of compensation-seeking MTBI patients and the other consisting of non-compensation-seeking MTBI patients. Results indicated significant differences on several scales and subscales between the two MTBI groups, with the compensation-seeking MTBI patients having significantly higher elevations on scales related to somatic preoccupation (Somatic Complaint Scale, SOM), emotional distress (Anxiety Scale, ANX; Anxiety Related Disorders Scale, ARD; Depression Scale, DEP), and the Negative Impression Management, NIM, validity scale. All the SOM subscales and the Anxiety Cognitive (ANX-C) and ANX Affective, ANX-A, subscales were also elevated in the compensation-seeking group. Results indicated that several scales on the PAI were sensitive to group differences in compensation-seeking status in MTBI patients. PMID:22136511

    This study modified and evaluated the psychometric properties of the Reasons for Living Inventory (RFL) in samples of adolescents. Internal consistency reliability, corrected item-total scale correlation, and exploratory factor analysis procedures were used with a mixed sample of 260 adolescents to identify 14 items for the brief version of the RFL (BRFL-A). Confirmatory factor analyses provided support for the five-factor oblique structure of the BRFL-A in a psychiatric inpatient sample with a range of suicidal behaviors. Reliabilities of the BRFL-A subscales were satisfactory. Four of the five subscales differentiated between suicidal and nonsuicidal adolescents. Significant correlations were found between three BRFL-A subscales and several suicide indices. Convergent-discriminant validity was examined by correlating the BRFL-A subscales with the Minnesota Multiphasic Personality Inventory-Adolescents (MMPI-A) Content Scales. Limitations of the study are discussed. PMID:8886940

    Several variables have been identified as risk factors for conversion to overt psychosis in ultra-high risk for psychosis (UHR) individuals. Although almost two-thirds of them do not experience a transition to psychosis, they still exhibit functional disabilities. Other subjective developmental features may be useful for a more precise identification of individuals at UHR. Avoidant behaviors are consistently reported in schizophrenia and in UHR individuals and may be the reflection of a pattern of personality. Thus, personality features in UHR individuals deserves further research. The objective of the present study was to compare temperament and character dimensions between UHR individuals, patients with schizophrenia and healthy controls. One hundred participants (25 UHR individuals, 25 schizophrenia patients and 50 control subjects) where evaluated with the Temperament and Character Inventory-Revised (TCI-R). Univariate ANOVAs followed by Bonferroni tests were used. UHR individuals and schizophrenia patients exhibited higher levels of Harm Avoidance (HA) when compared to control subjects. For HA1 Anticipatory worry vs Uninhibited optimism and HA4 Fatigability & asthenia, UHR and schizophrenia groups showed similar scores and both groups were higher compared to control subjects. With respect to Cooperativeness (CO), UHR and schizophrenia reported lower scores than control subjects, in particular CO2 Empathy vs Social disinterest and CO3 Helpfulness vs unhelpfulness. This study replicates and extends the consideration of HA as a psychopathological related endophenotype and gives us further information of the possible role of personality features in the expression of some of the social dysfunctions observed both in prodromal subjects and schizophrenia patients.

    Environmental risk assessment of chemicals is reliant on good estimates of product usage information and robust exposure models. Over the past 20 to 30 years, much progress has been made with the development of exposure models that simulate the transport and distribution of chemicals in the environment. However, little progress has been made in our ability to estimate chemical emissions of home and personal care (HPC) products. In this project, we have developed an approach to estimate subnational emission inventory of chemical ingredients used in HPC products for 12 Asian countries including Bangladesh, Cambodia, China, India, Indonesia, Laos, Malaysia, Pakistan, Philippines, Sri Lanka, Thailand, and Vietnam (Asia-12). To develop this inventory, we have coupled a 1 km grid of per capita gross domestic product (GDP) estimates with market research data of HPC product sales. We explore the necessity of accounting for a population's ability to purchase HPC products in determining their subnational distribution in regions where wealth is not uniform. The implications of using high resolution data on inter- and intracountry subnational emission estimates for a range of hypothetical and actual HPC product types were explored. It was demonstrated that for low value products (<500 US$ per capita/annum required to purchase product) the maximum deviation from baseline (emission distributed via population) is less than a factor of 3 and it would not result in significant differences in chemical risk assessments. However, for other product types (>500 US$ per capita/annum required to purchase product) the implications on emissions being assigned to subnational regions can vary by several orders of magnitude. The implications of this on conducting national or regional level risk assessments may be significant. Further work is needed to explore the implications of this variability in HPC emissions to enable the HPC industry and/or governments to advance risk-based chemical

    The current study was designed to identify personality subtypes on the basis of the five-factor model dimensions in male prisoners. Participants included 110 Flemish male prisoners assessed by means of the Neuroticism, Extraversion, Openness Five Factor Inventory and different symptom, personality, and coping measures. We found two clusters: an emotionally stable/resilient cluster and an aggressive/undercontrolled cluster. Prisoners within the aggressive/undercontrolled cluster scored significantly higher on almost all Minnesota Multiphasic Personality Inventory-2 basic scales, (in)direct aggression measures, and depressive coping scales compared with resilients. They also scored higher on drug abuse and committed more sexual offenses than resilient prisoners. These two personality subtypes bear theoretically and practically important implications for psychopathy subtypes and different pathways to criminal offenses. PMID:23123385

    Measurement of multiphase flow of gas, oil and water is not at all trivial and in spite of considerable achievements over the past two decades, important challenges remain (Corneliussen et al., 2005). These are related to reducing measurement uncertainties arising from variations in the flow regime, improving long term stability and developing new means for calibration, adjustment and verification of the multiphase flow meters. This work focuses on the first two issues using multi gamma beam (MGB) measurements for identification of the type of flow regime. Further gamma ray tomographic measurements are used for reference of the gas/liquid distribution. For the MGB method one Am-241 source with principal emission at 59.5 keV is used because this relatively low energy enables efficient collimation and thereby shaping of the beams, as well as compact detectors. One detector is placed diametrically opposite the source whereas the second is positioned to the side so that this beam is close to the pipe wall. The principle is then straight forward to compare the measured intensities of these detectors and through that identify the flow pattern, i.e. the instantaneous cross-sectional gas-liquid distribution. The measurement setup also includes Compton scattering measurements, which can provide information about the changes in the water salinity for flow segments with high water liquid ratio and low gas fractions. By measuring the transmitted intensity in short time slots (<100 ms), rapid regime variations are revealed. From this we can select the time sections suitable for salinity measurements. Since the salinity variations change at the time scale of hours, a running average can be performed to increase the accuracy of the measurements. Recent results of this work will be presented here.

    Research to date has revealed divergent relations across factors of psychopathy measures with criteria of internalizing (INT; anxiety, depression) and externalizing (EXT; antisocial behavior, substance use). However, failure to account for method variance and suppressor effects has obscured the consistency of these findings across distinct measures of psychopathy. Using a large correctional sample, the current study employed a multi-method approach to psychopathy assessment (self-report, interview/file review) to explore convergent and discriminant relations between factors of psychopathy measures and latent criteria of INT and EXT derived from the Personality Assessment Inventory (PAI; L. Morey, 2007). Consistent with prediction, scores on the affective-interpersonal factor of psychopathy were negatively associated with INT and negligibly related to EXT, whereas scores on the social deviance factor exhibited positive associations (moderate and large, respectively) with both INT and EXT. Notably, associations were highly comparable across the psychopathy measures when accounting for method variance (in the case of EXT) and when assessing for suppressor effects (in the case of INT). Findings are discussed in terms of implications for clinical assessment and evaluation of the validity of interpretations drawn from scores on psychopathy measures. PMID:20230156

    Cross-cultural investigation of psychopathy measures is important for clarifying the nomological network surrounding the psychopathy construct. The Psychopathic Personality Inventory-Revised (PPI-R) is one of the most extensively researched self-report measures of psychopathic traits in adults. To date however, it has been examined primarily in North American criminal or student samples. To address this gap in the literature, we examined PPI-R's reliability, construct validity and factor structure in non-criminal individuals (N = 227) in Sweden, using a multimethod approach including psychophysiological correlates of empathy for pain. PPI-R construct validity was investigated in subgroups of participants by exploring its degree of overlap with (i) the Psychopathy Checklist: Screening Version (PCL:SV), (ii) self-rated empathy and behavioral and physiological responses in an experiment on empathy for pain, and (iii) additional self-report measures of alexithymia and trait anxiety. The PPI-R total score was significantly associated with PCL:SV total and factor scores. The PPI-R Coldheartedness scale demonstrated significant negative associations with all empathy subscales and with rated unpleasantness and skin conductance responses in the empathy experiment. The PPI-R higher order Self-Centered Impulsivity and Fearless Dominance dimensions were associated with trait anxiety in opposite directions (positively and negatively, respectively). Overall, the results demonstrated solid reliability (test-retest and internal consistency) and promising but somewhat mixed construct validity for the Swedish translation of the PPI-R. PMID:27300292

    There has been a substantial increase in the use of personality assessment measures constructed using items from the International Personality Item Pool (IPIP) such as the 300-item IPIP-NEO (Goldberg, 1999), a representation of the Revised NEO Personality Inventory (NEO PI-R; Costa & McCrae, 1992). The IPIP-NEO is free to use and can be modified to accommodate its users' needs. Despite the substantial interest in this measure, there is still a dearth of data demonstrating its convergence with the NEO PI-R. The present study represents an investigation of the reliability and validity of scores on the IPIP-NEO. Additionally, we used item response theory (IRT) methodology to create a 120-item version of the IPIP-NEO. Using an undergraduate sample (n = 359), we examined the reliability, as well as the convergent and criterion validity, of scores from the 300-item IPIP-NEO, a previously constructed 120-item version of the IPIP-NEO (Johnson, 2011), and the newly created IRT-based IPIP-120 in comparison to the NEO PI-R across a range of outcomes. Scores from all 3 IPIP measures demonstrated strong reliability and convergence with the NEO PI-R and a high degree of similarity with regard to their correlational profiles across the criterion variables (rICC = .983, .972, and .976, respectively). The replicability of these findings was then tested in a community sample (n = 757), and the results closely mirrored the findings from Sample 1. These results provide support for the use of the IPIP-NEO and both 120-item IPIP-NEO measures as assessment tools for measurement of the five-factor model. PMID:24932643

    Increasingly, mental health and medical professionals have been asked to assess claims of psychological harm arising from harassment at the workplace, or "mobbing." This study assessed the personality and psychopathological profiles of 146 individuals exposed to mobbing using validity, clinical, and content scales of the Minnesota Multiphasic Personality Inventory 2. Profiles and factor analyses were obtained. Two major dimensions emerged among those exposed to mobbing: (a) depressed mood, difficulty in making decisions, change-related anguish, and passive-aggressive traits (b) somatic symptoms, and need for attention and affection. This cross-sectional pilot study provides evidence that personality profiles of mobbing victims and psychological damage resulting from mobbing may be evaluated using standardized assessments, though a longitudinal study is needed to delineate cause-and-effect relationships.

A total of 12 recidivists and 12 nonrecidivists were classified according to their index offenses, and a Criminal Record search was completed to verify their statements. A total of 15 non-offenders who had also undergone a criminal record check were included as controls. All participants were administered the Minnesota Multiphasic Personality Inventory-168, Violence Risk Scale-Experimental Version, Coopersmith Self-esteem Inventory, and the Wisconsin Card Sorting Task. Statistical analysis showed significant differences between the groups on scores for the Hypochondriasis, Psychopathic Deviate, and Hypomania scales of the MMPI-168. Significant differences were noted for the Wisconsin Card Sorting Task and the Violence Risk Scale. Discriminant analysis of the recidivists and nonrecidivists correctly classified at a 91.3% level.

  6. Methods of inventory control.

    Lindley, C; Mackowiak, J

    1985-01-01

    Various methods for controlling inventory are described, and the advantages and disadvantages of each are discussed. The open-to-buy (OTB) budget method limits purchases to a specific amount of funds available for purchasing pharmaceuticals during a specified period. The emphasis of the OTB method is financial control of the pharmacy inventory. Although it is useful in monitoring and adjusting the dollar value of the inventory, it should be combined with other methods for a total inventory control system. The primary emphasis of the short-list method is to provide accurate and timely inventory information to the person responsible for order placement. The short list identifies the items that are in short supply. It is the most common feedback and control mechanism in use, but it is best suited for settings where duplicate or reserve stock is maintained and monitored by more rigorous methods. The main objective of the minimum and maximum method is to determine when and how much to order of each item. It also provides limited dollar control. The major disadvantage of this method is the time it requires to establish the minimum and maximum levels and to update them regularly to reflect changes in demand. The stock record card method is used to record information on the movement of goods in and out of the storage area. Stock cards can also be used to monitor inventory levels and facilitate order initiation. It is probably the optimum method to be used alone. The most effective system of inventory control is one employing a combination of these methods tailored to meet the institution's needs and available resources. PMID:3970028

  9. Correlations of MMPI factor scales with measures of the five factor model of personality.

    PubMed

    Costa, P T; Busch, C M; Zonderman, A B; McCrae, R R

    1986-01-01

    Two recent item factor analyses of the Minnesota Multiphasic Personality Inventory (MMPI) classified the resulting factors according to a conceptual scheme offered by Norman's (1963) five factor model. The present article empirically evaluates those classifications by correlating MMPI factor scales with self-report and peer rating measures of the five factor model in a sample of 153 adult men and women. Both sets of predictions were generally supported, although MMPI factors derived in a normal sample showed closer correspondences with the five normal personality dimensions. MMPI factor scales were also correlated with 18 scales measuring specific traits within the broader domains of Neuroticism, Extraversion, and Openness. The nine Costa, Zonderman, McCrae, and Williams (1985) MMPI factor scales appear to give useful global assessments of four of the five factors; other instruments are needed to provide detailed information on more specific aspects of normal personality. The use of the five factor model in routine clinical assessment is discussed. PMID:3820053

  10. The prejudiced personality, racism, and anti-Semitism: the PR scale forty years later.

    PubMed

    Dunbar, E

    1995-10-01

    The relationship of prejudiced personality traits with racism and anti-Semitism was examined with 150 Asian American and White university students. The Prejudice (PR) scale, composed of 32 items from the Minnesota Multiphasic Personality Inventory, was administered along with the McConahay racism scale and the Selznick and Steinberg Anti-Semitism scale. Results indicated that for Whites, the PR scale was significantly correlated with old-fashioned and modern racism and anti-Semitism, replicating Gough's 1951 study (Gough, 1951b) with the PR scale. However, no such relationship was observed for the Asian American group. This suggests that personality traits of prejudicial attitudes may be relatively stable for Whites but may not be related to outgroup bias for other racial or ethnic groups. PMID:8656327

    Deficits in gratification delay are associated with a broad range of public health problems, such as obesity, risky sexual behavior, and substance abuse. However, six decades of research on the construct has progressed less quickly than might be hoped, largely due to measurement issues. Although past research implicates five domains of delay behavior, involving food, physical pleasures, social interactions, money, and achievement, no published measure to date has tapped all five components of the content domain. Existing measures have been criticized for limitations related to efficiency, reliability, and construct validity. Using an innovative Internet-mediated approach to survey construction, we developed the 35-item five-factor Delaying Gratification Inventory (DGI). Evidence from four studies and a large, diverse sample of respondents (N = 10,741) provided support for the psychometric properties of the measure. Specifically, scores on the DGI demonstrated strong internal consistency and test-retest reliability for the 35-item composite, each of the five domains, and a 10-item short-form. The five-factor structure fit the data well and had good measurement invariance across subgroups. Construct validity was supported by correlations with scores on closely-related self-control measures, behavioral ratings, Big Five personality trait measures, and measures of adjustment and psychopathology, including those on the Minnesota Multiphasic Personality Inventory-2-Restructured Form (MMPI-2-RF). DGI scores also showed incremental validity in accounting for well-being and health-related variables. The present investigation holds implications for improving public health, accelerating future research on gratification delay, and facilitating survey construction research more generally by demonstrating the suitability of an Internet-mediated strategy.

    This study examined associations between childhood abuse and personality disturbances in 228 drug-dependent women. Thirty-six percent denied abuse, 50% reported emotional, 42% physical, and 42% sexual abuse. Million Clinical Multiarial Inventory (MCMI-III) scores > 74 provided evidence of personality disturbance and scores on Minnesota Multiphasic Personality Inventory-2 (MMPI-2) scales measuring somatic complaints, depression, anxiety and postraumatic stress disorder (PTSD) served as covariates. Emotional and physical abuse survivors were at increased risk for borderline, masochistic, and avoidant disturbances and decreased risk for narcissistic disturbances. Emotional abuse survivors were also less likely to be sadistic whereas physical abuse survivors were more likely to be paranoid. Sexual abuse survivors were twice as likely be antisocial; however, no association was found with borderline personality. Finally, an increased prevalence of severe personality disturbances was observed among those experiencing multiple types of abuse. Childhood trauma predisposes drug-dependent women to develop troublesome personality characteristics that are independent of drug addiction and other psychological problems associated with childhood trauma.

    2003-01-01

    Thus we conduct numerical simulations of multiphase fluids stirred by two-dimensional turbulence to assess the possibility of self-similar drop size distribution in turbulence. In our turbulence simulations, we also explore the non-diffusive limit, where molecular mobility for the interface is vanishing. Special care is needed to transport the non-diffusive interface. Numerically, we use the particle level set method to evolve the interface. Instead of using the usual methods to calculate the surface tension force from the level set function, we reconstruct the interface based on phase- field modeling, and calculate the continuum surface tension forcing from the reconstructed interface.

  17. Clinical utility of the Neurobehavioral Symptom Inventory validity scales to screen for symptom exaggeration following traumatic brain injury.

    2015-01-01

    The purpose of this study was to examine the clinical utility of three recently developed validity scales (Validity-10, NIM5, and LOW6) designed to screen for symptom exaggeration using the Neurobehavioral Symptom Inventory (NSI). Participants were 272 U.S. military service members who sustained a mild, moderate, severe, or penetrating traumatic brain injury (TBI) and who were evaluated by the neuropsychology service at Walter Reed Army Medical Center within 199 weeks post injury. Participants were divided into two groups based on the Negative Impression Management scale of the Personality Assessment Inventory: (a) those who failed symptom validity testing (SVT-fail; n = 27) and (b) those who passed symptom validity testing (SVT-pass; n = 245). Participants in the SVT-fail group had significantly higher scores (p<.001) on the Validity-10, NIM5, LOW6, NSI total, and Personality Assessment Inventory (PAI) clinical scales (range: d = 0.76 to 2.34). Similarly high sensitivity, specificity, positive predictive power (PPP), and negative predictive (NPP) values were found when using all three validity scales to differentiate SVT-fail versus SVT-pass groups. However, the Validity-10 scale consistently had the highest overall values. The optimal cutoff score for the Validity-10 scale to identify possible symptom exaggeration was ≥19 (sensitivity = .59, specificity = .89, PPP = .74, NPP = .80). For the majority of people, these findings provide support for the use of the Validity-10 scale as a screening tool for possible symptom exaggeration. When scores on the Validity-10 exceed the cutoff score, it is recommended that (a) researchers and clinicians do not interpret responses on the NSI, and (b) clinicians follow up with a more detailed evaluation, using well-validated symptom validity measures (e.g., Minnesota Multiphasic Personality Inventory-2 Restructured Form, MMPI-2-RF, validity scales), to seek confirmatory evidence to support an hypothesis of symptom exaggeration

    Van Hooft and Born (Journal of Applied Psychology 97:301-316, 2012) presented data challenging both the correctness of a congruence model of faking on personality test items and the relative merit (i.e., effect size) of response latencies for identifying fakers. We suggest that their analysis of response times was suboptimal, and that it followed neither from a congruence model of faking nor from published protocols on appropriately filtering the noise in personality test item answering times. Using new data and following recommended analytic procedures, we confirmed the relative utility of response times for identifying personality test fakers, and our obtained results, again, reinforce a congruence model of faking.

    Multiphase reactors are very common in chemical industry, and numerous review articles exist that are focused on types of reactors, such as bubble columns, trickle beds, fluid catalytic beds, etc. Currently, there is a high degree of empiricism in the design process of such reactors owing to the complexity of coupled flow and reaction mechanisms. Hence, we focus on synthesizing recent advances in computational and experimental techniques that will enable future designs of such reactors in a more rational manner by exploring a large design space with high-fidelity models (computational fluid dynamics and computational chemistry models) that are validated with high-fidelity measurements (tomography and other detailed spatial measurements) to provide a high degree of rigor. Understanding the spatial distributions of dispersed phases and their interaction during scale up are key challenges that were traditionally addressed through pilot scale experiments, but now can be addressed through advanced modeling.

    The authors understanding of multiphase physics and the associated predictive capability for multi-phase systems are severely limited by current continuum modeling methods and experimental approaches. This research will deliver an unprecedented modeling capability to directly simulate three-dimensional multi-phase systems at the particle-scale. The model solves the fully coupled equations of motion governing the fluid phase and the individual particles comprising the solid phase using a newly discovered, highly efficient coupled numerical method based on the discrete-element method and the Lattice-Boltzmann method. A massively parallel implementation will enable the solution of large, physically realistic systems.

    This study examined neuropsychological prognosis following organic solvent exposure. Twenty-seven persons with evidence of 'mild toxic encephalopathy' were evaluated on two separate occasions with a standard neuropsychological test battery and the Minnesota Multiphasic Personality Inventory. Ratings by experienced clinicians revealed that 50% of exposed persons had improved neuropsychological performance at the second evaluation. The other 50% were rated as having no change or a decline in neuropsychological tests scores. While the majority of persons in the good-outcome group were working at the time of the follow-up evaluation, none of the persons in the poor-outcome group was actively employed. Persons rated as having shown no improvement were significantly more likely to have had a peak exposure--an episode in which they were briefly exposed to a larger than normal amount of solvent. In addition, persons in the poor outcome group reported higher levels of psychological distress, both initially and at the follow-up evaluation. Results from this study suggest that the presence of certain risk factors, namely a peak exposure and psychological distress, may be particularly detrimental for long-term neuropsychological outcome in persons with a history of organic solvent exposure.

(2) Recommend, including a basis thereof, a set of radionuclides that should be modeled in the Total System Performance Assessment in Support of the Site Recommendation (TSPA-SR) and the Total System Performance Assessment in Support of the Final Environmental Impact Statement (TSPA-FEIS). (3) Provide initial radionuclide inventories for the TSPA-SR and TSPA-FEIS models. (4) Answer the U.S. Nuclear Regulatory Commission (NRC)'s Issue Resolution Status Report ''Key Technical Issue: Container Life and Source Term'' (CLST IRSR) key technical issue (KTI): ''The rate at which radionuclides in SNF [spent nuclear fuel] are released from the EBS [engineered barrier system] through the oxidation and dissolution of spent fuel'' (NRC 1999, Subissue 3). The scope of the radionuclide screening analysis encompasses the period from 100 years to 10,000 years after the potential repository at Yucca Mountain is sealed for scenarios involving the breach of a waste package and subsequent degradation of the waste form as required for the TSPA-SR calculations. By extending the time period considered to one million years after repository closure, recommendations are made for the TSPA-FEIS. The waste forms included in the inventory abstraction are Commercial Spent Nuclear Fuel (CSNF), DOE Spent Nuclear Fuel (DSNF), High-Level Waste (HLW), naval Spent Nuclear Fuel (SNF), and U.S. Department of Energy (DOE) plutonium waste. The intended use of this analysis is in TSPA-SR and TSPA-FEIS. Based on the recommendations made here, models for release, transport, and possibly exposure will be developed for the isotopes that would be the highest contributors to the dose given a release to the

    2013-01-01

    Immiscible aqueous phases, formed by dissolving incompatible solutes in water, have been used in green chemical synthesis, molecular extraction and mimicking of cellular cytoplasm. Recently, a microfluidic approach has been introduced to generate all-aqueous emulsions and jets based on these immiscible aqueous phases; due to their biocompatibility, these all-aqueous structures have shown great promises as templates for fabricating biomaterials. The physico-chemical nature of interfaces between two immiscible aqueous phases leads to unique interfacial properties, such as an ultra-low interfacial tension. Strategies to manipulate components and direct their assembly at these interfaces needs to be explored. In this paper, we review progress on the topic over the past few years, with a focus on the fabrication and stabilization of all-aqueous structures in a multiphase microfluidic platform. We also discuss future efforts needed from the perspectives of fluidic physics, materials engineering, and biology for fulfilling potential applications ranging from materials fabrication to biomedical engineering.

    1979-01-01

    A survey is presented of diagnostic techniques and measurements made in multiphase reacting flows. The special problems encountered by the presence of liquid droplets, soot and solid particles in high temperature chemically reacting turbulent environments are outlined. The principal measurement techniques that have been tested in spray flames are spark photography, laser anemometry, thermocouples and suction probes. Spark photography provides measurement of drop size, drop size distribution, drop velocity, and angle of flight. Photographs are analysed automatically by image analysers. Photographic techniques are reliable, inexpensive and proved. Laser anemometers have been developed for simultaneous measurement of velocity and size of individual particles in sprays under conditions of vaporization and combustion. Particle/gas velocity differentials, particle Reynolds numbers, local drag coefficients and direct measurement of vaporization rates can be made by laser anemometry. Gas temperature in sprays is determined by direct in situ measurement of time constants immediately prior to measurement with compensation and signal analysis by micro-processors. Gas concentration is measured by suction probes and gas phase chromatography. Measurements of particle size, particle velocity, gas temperature, and gas concentration made in airblast and pressure atomised liquid spray flames are presented.

  13. Experimental techniques for multiphase flows

    NASA Astrophysics Data System (ADS)

    Powell, Robert L.

    2008-04-01

    This review discusses experimental techniques that provide an accurate spatial and temporal measurement of the fields used to describe multiphase systems for a wide range of concentrations, velocities, and chemical constituents. Five methods are discussed: magnetic resonance imaging (MRI), ultrasonic pulsed Doppler velocimetry (UPDV), electrical impedance tomography (EIT), x-ray radiography, and neutron radiography. All of the techniques are capable of measuring the distribution of solids in suspensions. The most versatile technique is MRI, which can be used for spatially resolved measurements of concentration, velocity, chemical constituents, and diffusivity. The ability to measure concentration allows for the study of sedimentation and shear-induced migration. One-dimensional and two-dimensional velocity profiles have been measured with suspensions, emulsions, and a range of other complex liquids. Chemical shift MRI can discriminate between different constituents in an emulsion where diffusivity measurements allow the particle size to be determined. UPDV is an alternative technique for velocity measurement. There are some limitations regarding the ability to map complex flow fields as a result of the attenuation of the ultrasonic wave in concentrated systems that have high viscosities or where multiple scattering effects may be present. When combined with measurements of the pressure drop, both MRI and UPDV can provide local values of viscosity in pipe flow. EIT is a low cost means of measuring concentration profiles and has been used to study shear-induced migration in pipe flow. Both x-ray and neutron radiographes are used to image structures in flowing suspensions, but both require highly specialized facilities.

  14. Multiphase modelling of mud volcanoes

    NASA Astrophysics Data System (ADS)

    Colucci, Simone; de'Michieli Vitturi, Mattia; Clarke, Amanda B.

    2015-04-01

    Mud volcanism is a worldwide phenomenon, classically considered as the surface expression of piercement structures rooted in deep-seated over-pressured sediments in compressional tectonic settings. The release of fluids at mud volcanoes during repeated explosive episodes has been documented at numerous sites and the outflows resemble the eruption of basaltic magma. As magma, the material erupted from a mud volcano becomes more fluid and degasses while rising and decompressing. The release of those gases from mud volcanism is estimated to be a significant contributor both to fluid flux from the lithosphere to the hydrosphere, and to the atmospheric budget of some greenhouse gases, particularly methane. For these reasons, we simulated the fluid dynamics of mud volcanoes using a newly-developed compressible multiphase and multidimensional transient solver in the OpenFOAM framework, taking into account the multicomponent nature (CH4, CO2, H2O) of the fluid mixture, the gas exsolution during the ascent and the associated changes in the constitutive properties of the phases. The numerical model has been tested with conditions representative of the LUSI, a mud volcano that has been erupting since May 2006 in the densely populated Sidoarjo regency (East Java, Indonesia), forcing the evacuation of 40,000 people and destroying industry, farmland, and over 10,000 homes. The activity of LUSI mud volcano has been well documented (Vanderkluysen et al., 2014) and here we present a comparison of observed gas fluxes and mud extrusion rates with the outcomes of numerical simulations.

    [Purpose] The aim of this study was to assess the effectiveness of a 6-week aerobic exercise program on pain, physical function, and psychological status, and to evaluate the personality characteristics of fibromyalgia syndrome (FMS) patients. [Subjects and Methods] Fourteen women with FMS were enrolled. They were trained for a 6-week home-based aerobic exercise program. The Fibromyalgia Impact Questionnaire, the Beck Depression Inventory, the visual analog scale of pain and sleep quality were measured at baseline and at the end of week 6. The personality profiles were evaluated using the Minnesota Multiphasic Personality Inventory (MMPI). [Results] After the exercise program, significant improvements were determined in pain, sleep quality, physical function, depression and FMS symptoms compared to baseline. In addition, the hysteria item (71.21±8.84) of the MMPI was significantly higher in FMS. [Conclusion] Our findings indicate that home-based aerobic exercise may be a useful treatment in the management of FMS. Personality characteristics should be considered during the planning process of the treatment of FMS. Personality is a filter between life events and psychological responses. It is defined to be the integration of effective and behavioral patterns. Long-term studies involving larger clinical samples are needed to define the role of personality characteristics in FMS.

    Research on multiphase flows is very important for industrial applications, including power stations, vehicles, engines, food processing and so on. Multiphase flows originally have nonlinear features because of multiphase systems. The interaction between the phases plays a very interesting role in the flows. The nonlinear interaction causes the multiphase flows to be very complicated. Therefore techniques for measuring multiphase flows are very useful in helping to understand the nonlinear phenomena. The state-of-the-art measurement techniques were presented and discussed at the sixth International Symposium on Measurement Techniques for Multiphase Flows (ISMTMF2008) held in Okinawa, Japan, on 15-17 December 2008. This special feature of Measurement Science and Technology includes selected papers from ISMTMF2008. Okinawa has a long history as the Ryukyus Kingdom. China, Japan and many western Pacific countries have had cultural and economic exchanges through Okinawa for over 1000 years. Much technical and scientific information was exchanged at the symposium in Okinawa. The proceedings of ISMTMF2008 apart from these special featured papers were published in Journal of Physics: Conference Series vol. 147 (2009). We would like to express special thanks to all the contributors to the symposium and this special feature. This special feature will be a milestone in measurement techniques for multiphase flows.

    This paper investigates the inhibition performance of a typical imidazoline based inhibitor under multiphase flow. Electrochemical impedance spectroscopy (EIS) measurements were carried out in a 101.6 mm I.D., 15 m long acrylic flow loop using ASTM substitute saltwater and carbon dioxide gas. This flow loop system can generate slug flow, fill pipe flow and other multiphase flow patterns. Effects of different flow conditions on inhibition performance of this typical inhibitor were examined. The system was maintained at a pressure of 0.136 MPa and a temperature of 40 C. EIS measurements for this inhibitor in a Rotating Cylinder Electrode (RCE) system were also conducted. Different equivalent circuit models were used to fit the experiment data for both the RCE and flow loop systems. The high shear stress and turbulence due to the mixing vortex and the bubble impact in multiphase flow can enhance the corrosion or reduce the inhibition performance of inhibitors.

    Cross-cultural investigation of psychopathy measures is important for clarifying the nomological network surrounding the psychopathy construct. The Psychopathic Personality Inventory-Revised (PPI-R) is one of the most extensively researched self-report measures of psychopathic traits in adults. To date however, it has been examined primarily in North American criminal or student samples. To address this gap in the literature, we examined PPI-R’s reliability, construct validity and factor structure in non-criminal individuals (N = 227) in Sweden, using a multimethod approach including psychophysiological correlates of empathy for pain. PPI-R construct validity was investigated in subgroups of participants by exploring its degree of overlap with (i) the Psychopathy Checklist: Screening Version (PCL:SV), (ii) self-rated empathy and behavioral and physiological responses in an experiment on empathy for pain, and (iii) additional self-report measures of alexithymia and trait anxiety. The PPI-R total score was significantly associated with PCL:SV total and factor scores. The PPI-R Coldheartedness scale demonstrated significant negative associations with all empathy subscales and with rated unpleasantness and skin conductance responses in the empathy experiment. The PPI-R higher order Self-Centered Impulsivity and Fearless Dominance dimensions were associated with trait anxiety in opposite directions (positively and negatively, respectively). Overall, the results demonstrated solid reliability (test-retest and internal consistency) and promising but somewhat mixed construct validity for the Swedish translation of the PPI-R. PMID:27300292

    Impulse control disorders (ICDs) are clinically relevant in Parkinson disease (PD) patients, with an established association with PD medication. Aim of our study was to study whether the increased frequency of pathological gambling (PG), reported in subgroups of PD patients, is related to specific personality tracts additional to dopaminergic medications. Thirty-seven PD patients with a personal history of PG where enrolled. Twenty one PD patients, matched for disease and dopaminergic therapy, never experiencing PG, were enrolled as controls. All subjects were tested with the Minnesota Multiphasic Inventory Personality scales (MMPI-2). Our data showed that PD group with PG exhibited significantly higher mean values of the three validity scales in comparison to the non-PG-PD group, demonstrating an higher tendency to lie. Content scales showed a significant increase of cynicism and bizarre ideation scales score in the PG-PD group, not exhibiting pathological values at the validity scales, (p: 0.02) in comparison to non-PG PD patients. According to our results, PG seems to be associated with precise personality tracts. Personality profiles of cluster A personality disturbances - Axys 2 according with DSM-5 TR (paranoid type) at MMPI-2 might be a warning index helpful in selecting dopaminergic treatment, to avoid subsequent ICDs appearance.

    Personality researchers have recently advocated the use of very short personality inventories in order to minimize administration time. However, few such inventories are currently available. Here I introduce an automated method that can be used to abbreviate virtually any personality inventory with minimal effort. After validating the method against existing measures in Studies 1 and 2, a new 181-item inventory is generated in Study 3 that accurately recaptures scores on 8 different broadband inventories comprising 203 distinct scales. Collectively, the results validate a powerful new way to improve the efficiency of personality measurement in research settings. PMID:20419061

    This paper examines the distribution of national personality dimensions in geographical space. The relationship between geographical location and aggregate personality in a wide range of nations is quantified using spatial autocorrelation, and it is found that the personalities of nations that are geographical neighbours are more similar than those that are far apart. The five factors of both the Revised NEO Personality Inventory (NEO-PI-R) and the Big Five Inventory (BFI), all show a significant degree of spatial organization. The personality factors most strongly associated with geographical location are NEO-PI-R extraversion and BFI conscientiousness; both vary with position around the globe about as much as the physical climate. These findings support previous research suggesting associations between aggregate personality and geography, and imply that the sources of variation in national personality are themselves geographically organized.

    Constraints on the clustered mass density of the universe derived from the observed population mean intracluster gas fraction of x-ray clusters may be biased by reliance on a single-phase assumption for the thermodynamic structure of the intracluster medium (ICM). We propose a descriptive model for multiphase structure in which a spherically symmetric ICM contains isobaric density perturbations with a radially dependent variance. Fixing the x-ray emission and emission weighted temperature, we explore two independently observable signatures of the model in the parameter space. For bremsstrahlung dominated emission, the central Sunyaev-Zel'dovich (SZ) decrement in the multiphase case is increased over the single-phase case and multiphase x-ray spectra in the range 0.1-20 keV are flatter in the continuum and exhibit stronger low energy emission lines than their single-phase counterpart. We quantify these effects for a fiducial 10e8 K cluster and demonstrate how the combination of SZ and x-ray spectroscopy can be used to identify a preferred location in the plane of the model parameter space. From these parameters the correct value of mean intracluster gas fraction in the multiphase model results, allowing an unbiased estimate of clustered mass density to he recovered.

  8. Multiphase Instabilities in Explosive Dispersal of Particles

    Explosive dispersal of particles is a complex multiphase phenomenon that can be observed in volcanic eruptions or in engineering applications such as multiphase explosives. As the layer of particles moves outward at high speed, it undergoes complex interactions with the blast-wave structure following the reaction of the energetic material. Particularly in this work, we are interested in the multiphase flow instabilities related to Richmyer-Meshkov (RM) and Rayleigh-Taylor (RM) instabilities (in the gas phase and particulate phase), which take place as the particle layer disperses. These types of instabilities are known to depend on initial conditions for a relatively long time of their evolution. Using a Eulerian-Lagrangian approach, we study the growth of these instabilities and their dependence on initial conditions related to the particulate phase - namely, (i) particle size, (ii) initial distribution, and (iii) mass ratio (particles to explosive). Additional complexities associated with compaction of the layer of particles are avoided here by limiting the simulations to modest initial volume fraction of particles. A detailed analysis of the initial conditions and its effects on multiphase RM/RT-like instabilities in the context of an explosive dispersal of particles is presented.

    On of the most important tools in production logging and well testing is the downhole flowmeter. Unfortunately, existing tools are inaccurate outside of an idealized single phase flow, regime. Spinner tools are inaccurate at extremely high or low, flow rates and when the flow rate is variable. Radioactive tracer tools have similar inaccuracies and are extremely sensitive to the flow regime. Both tools completely fail in the presence of multiphase flow, whether gas/ oil, gas/water or fluid/solid. Downhole flowmetering is important for locating producing zones and thief zones and monitoring production and injection rates. The effects of stimulation can also be determined. This goal of this project is the investigation of accurate downhole flowmetering techniques for all single phase flow regimes and multiphase flows. The measurement method investigated in this report is the use of ultrasound. There are two ways to use ultrasound for fluid velocity measurement. The first method, examined in Chapter 2, is the contrapropagation, or transit-time, method which compares travel times with and against fluid flow. Chapter 3 details the second method which measures the Doppler frequency shift of a reflected sound wave in the moving fluid. Both of these technologies need to be incorporated in order to build a true multiphase flowmeter. Chapter 4 describes the proposed downhole multiphase flowmeter. It has many advantages besides the ones previously mentioned and is in full in that chapter.

    1993-01-01

    This paper investigates multiphase railguns powered by multiphase compulsators. The polyphase system offers several advantages over the single phase system. The multiphase compulsator relaxes the strong dependence between the current pulse width necessary for the railgun and the design parameters of the generator (number or poles, rotor diameter, and tip speed) thus allowing the compulsator to be designed for optimum power density and electromechanical energy conversion. The paper examines in particular the two, three and six phase systems. The authors also explore different methods of achieving high acceleration ratios in multiphase railgun systems. Some of the methods analyzed are ramping up the field current of the compulsator to counter the back electromotive force of the gun, utilizing a railgun with varying inductance per unit length (L'), and using an external variable inductor in series with the compulsator. The different features of each method are highlighted using simulation results. Special attention is devoted to the external series inductor method which uses a rotary flux compressor. Simulation results indicate an encouraging acceleration ratio of 0.7 for a muzzle energy of 9 MJ. A disk configuration is envisioned for the flux compressor.

    Modern industrial systems assume different configurations to accomplish multiple objectives during different phases of operation, and the component parameters may also vary from one phase to the next. Consequently, reliability evaluation of complex multi-phased systems is a vital and challenging issue. Maximization of mission reliability of a multi-phase system via optimal asset selection is another key demand; incorporation of optimization issues adds to the complexities of reliability evaluation processes. Introduction of components having self-diagnostics and self-recovery capabilities, along with increased complexity and phase-dependent configuration variations in network architectures, requires new approaches for reliability evaluation. This paper considers the problem of evaluating the reliability of a complex multi-phased system with self-recovery/fault-protection options. The reliability analysis is based on a colored digraph (i.e., multi-functional) model that subsumes fault trees and digraphs as special cases. These models enable system designers to decide on system architecture modifications and to determine the optimum levels of redundancy. A sum of disjoint products (SDP) approach is employed to compute system reliability. We also formulated the problem of optimal asset selection in a multi-phase system as one of maximizing the probability of mission success under random load profiles on components. Different methods (e.g., ordinal optimization, robust design, and nonparametric statistical testing) are explored to solve the problem. The resulting analytical expressions and the software tool are demonstrated on a generic programmable software-controlled switchgear, a data bus controller system and a multi-phase mission involving helicopters.

    Background. To assess personality characteristics of women who develop perinatal depression. Methods. The study started with a screening of a sample of 453 women in their third trimester of pregnancy, to which was administered a survey data form, the Edinburgh Postnatal Depression Scale (EPDS) and the Minnesota Multiphasic Personality Inventory 2 (MMPI-2). A clinical group of subjects with perinatal depression (PND, 55 subjects) was selected; clinical and validity scales of MMPI-2 were used as predictors in hierarchical cluster analysis carried out. Results. The analysis identified three clusters of personality profile: two “clinical” clusters (1 and 3) and an “apparently common” one (cluster 2). The first cluster (39.5%) collects structures of personality with prevalent obsessive or dependent functioning tending to develop a “psychasthenic” depression; the third cluster (13.95%) includes women with prevalent borderline functioning tending to develop “dysphoric” depression; the second cluster (46.5%) shows a normal profile with a “defensive” attitude, probably due to the presence of defense mechanisms or to the fear of stigma. Conclusion. Characteristics of personality have a key role in clinical manifestations of perinatal depression; it is important to detect them to identify mothers at risk and to plan targeted therapeutic interventions.

    2015-11-01

    Multiphase flow is prevalent in a variety of industrial applications, but the extent of these processes is often limited by the innate mass transfer resistance across phase boundaries. Microscale multiphase systems, owing to their reduced characteristic length scales, increase specific interfacial areas and unique hydrodynamic patterns, can significantly enhance the rate of mass transfer, thereby improving the efficiency of multiphase processes. However, many uncertainties still remain in the prediction of multiphase hydrodynamics and scalar transport on the microscale, primarily due to the complex nature of the multiphase flow. In this work, to elucidate the mechanism of mass transfer enhancement in microscale multiphase flows, a computational fluid dynamic (CFD) model using the volume-of-fluid (VOF) method is developed, and the method is validated with experiments. By introducing a scalar transport equation with sink/source terms using the one-fluid formulation, we enable the simultaneous capturing of multi-phase hydrodynamics, mass transfer and reactions. In tandem with the numerical simulations, we also perform mass transfer analysis of multiphase flows based on the penetration theory and a two-stage theory, which further examines the mechanism of mixing enhancement in multiphase flow, and reveals a two-fold increase in mass transfer coefficients in the microreactors compared to conventional multiphase contactors.

  16. Multiphase complete exchange on a circuit switched hypercube

    NASA Technical Reports Server (NTRS)

    Bokhari, Shahid H.

    1991-01-01

    On a distributed memory parallel computer, the complete exchange (all-to-all personalized) communication pattern requires each of n processors to send a different block of data to each of the remaining n - 1 processors. This pattern is at the heart of many important algorithms, most notably the matrix transpose. For a circuit switched hypercube of dimension d(n = 2(sup d)), two algorithms for achieving complete exchange are known. These are (1) the Standard Exchange approach that employs d transmissions of size 2(sup d-1) blocks each and is useful for small block sizes, and (2) the Optimal Circuit Switched algorithm that employs 2(sup d) - 1 transmissions of 1 block each and is best for large block sizes. A unified multiphase algorithm is described that includes these two algorithms as special cases. The complete exchange on a hypercube of dimension d and block size m is achieved by carrying out k partial exchange on subcubes of dimension d(sub i) Sigma(sup k)(sub i=1) d(sub i) = d and effective block size m(sub i) = m2(sup d-di). When k = d and all d(sub i) = 1, this corresponds to algorithm (1) above. For the case of k = 1 and d(sub i) = d, this becomes the circuit switched algorithm (2). Changing the subcube dimensions d, varies the effective block size and permits a compromise between the data permutation and block transmission overhead of (1) and the startup overhead of (2). For a hypercube of dimension d, the number of possible combinations of subcubes is p(d), the number of partitions of the integer d. This is an exponential but very slowly growing function and it is feasible over these partitions to discover the best combination for a given message size. The approach was analyzed for, and implemented on, the Intel iPSC-860 circuit switched hypercube. Measurements show good agreement with predictions and demonstrate that the multiphase approach can substantially improve performance for block sizes in the 0 to 160 byte range. This range, which corresponds to

    Finsterle, S.; Zhang, Y.

    2010-12-01

    Parameter estimation by inverse modeling involves the repeated evaluation of a function of residuals. These residuals represent both errors in the model and errors in the data. In practical applications of inverse modeling of multiphase flow and transport, the error structure of the final residuals often significantly deviates from the statistical assumptions that underlie standard maximum likelihood estimation using the least-squares method. Large random or systematic errors are likely to lead to convergence problems, biased parameter estimates, misleading uncertainty measures, or poor predictive capabilities of the calibrated model. The multiphase inverse modeling code iTOUGH2 supports strategies that identify and mitigate the impact of systematic or non-normal error structures. We discuss these approaches and provide an overview of the error handling features implemented in iTOUGH2.

    The Rogn South subsea well has the world`s first commercial subsea multiphase boosting system. The well produces to A/S Norske Shell`s Draugen field, in the Norwegian Sea. The Smubs (Shell multiphase underwater booster station) provides additional energy to transport a mixture of gas and liquids over long distances. This reduces the back pressure on the reservoir to potentially enhance both production and recovery. In-house Shell International Petroleum Maatschappij B.V. (SIPM) has studied estimated facility costs and performance for a multiphase boosting system for a typical small (50 million bbl) field between 20--50 km from a host facility in water depths between 150--1,000 m. The studies showed that technical costs per barrel of oil produced could be cut by up to 30% compared to conventional technology. The Smubs main features are: A single retrievable cartridge that houses all active components susceptible to wear; No orientation requirements for the pump cartridge unit; No orientation requirements for the pump cartridge unit; Hydraulically set and tested seals; and Vertical installation and retrieval with a single tool, and a remotely operated vehicle (ROV) only for a monitoring.

    The petroleum industry has relied in the past mainly on conventional vessel-type separators, which are bulky, heavy and expensive, to process wellhead production of oil-water-gas flow. Economic and operational pressures continue to force the petroleum industry to seek less expensive and more efficient separation alternatives in the form of compact separators. The compact dimensions, smaller footprint and lower weight of compact separators have a potential for cost savings to the industry, especially in offshore and subsea applications. Also, compact separators reduce the inventory of hydrocarbons significantly, which is critical for environmental This report presents a brief overview of the activities and tasks accomplished during the Budget Period II (October 09, 2004-April 30, 2006) of the DOE project titled ''Design and Development of Integrated Compact Multiphase Separation System (CMSS{copyright})''. An executive summary is presented initially followed by the tasks of the current budget period. Then, detailed description of the experimental and modeling investigations are presented. Subsequently, the technical and scientific results of the activities of this project period are presented with discussions.

    Although concept inventories are among the most frequently used tools in the physics and astronomy education communities, they are rarely evaluated using item response theory (IRT). When IRT models fit the data, they offer sample-independent estimates of item and person parameters. IRT may also provide a way to measure students' learning gains…

  6. Multiphase pumps and flow meters avoid platform construction

    One of the newest wrinkles in efficiency in BP`s Eastern Trough Area Project (ETAP) is the system for moving multiphase oil, water and gas fluids from the Machar satellite field to the Marnock Central Processing Facility (CPF). Using water-turbine-driven multiphase pumps and multiphase flow meters, the system moves fluid with no need for a production platform. In addition, BP has designed the installation so it reduces and controls water coning, thereby increasing recoverable reserves. Both subsea multiphase booster stations (SMUBS) and meters grew out of extensive development work and experience at Framo Engineering AS (Framo) in multiphase meters and multiphase pump systems for subsea installation. Multiphase meter development began in 1990 and the first subsea multiphase meters were installed in the East Spar Project in Australia in 1996. By September 1998, the meters had been operating successfully for more than 1 year. A single multiphase meter installed in Marathon`s West Brae Project has also successfully operated for more than 1 year. Subsea meters for ETAP were installed and began operating in July 1998.

    1997-06-01

    The INEEL contractors and their associated facilities are required to identify all liquid effluent discharges that may impact the environment at the INEEL. This liquid effluent information is then placed in the Liquid Effluent Inventory (LEI) database, which is maintained by the INEEL prime contractor. The purpose of the LEI is to identify and maintain a current listing of all liquid effluent discharge points and to identify which discharges are subject to federal, state, or local permitting or reporting requirements and DOE order requirements. Initial characterization, which represents most of the INEEL liquid effluents, has been performed, and additional characterization may be required in the future to meet regulations. LEI information is made available to persons responsible for or concerned with INEEL compliance with liquid effluent permitting or reporting requirements, such as the National Pollutant Discharge Elimination System, Wastewater Land Application, Storm Water Pollution Prevention, Spill Prevention Control and Countermeasures, and Industrial Wastewater Pretreatment. The State of Idaho Environmental Oversight and Monitoring Program also needs the information for tracking liquid effluent discharges at the INEEL. The information provides a baseline from which future liquid discharges can be identified, characterized, and regulated, if appropriate. The review covered new and removed buildings/structures, buildings/structures which most likely had new, relocated, or removed LEI discharge points, and at least 10% of the remaining discharge points.

    Martinez, M.J.; Hopkins, P.L.; Shadid, J.N.

    1997-10-01

    We present a numerical method for nonisothermal, multiphase subsurface transport in heterogeneous porous media. The mathematical model considers nonisothermal two-phase (liquid/gas) flow, including capillary pressure effects, binary diffusion in the gas phase, conductive, latent, and sensible heat transport. The Galerkin finite element method is used for spatial discretization, and temporal integration is accomplished via a predictor/corrector scheme. Message-passing and domain decomposition techniques are used for implementing a scalable algorithm for distributed memory parallel computers. An illustrative application is shown to demonstrate capabilities and performance.

    The knowledge of the fundamental understanding such as composition-structure-mechanical property relationships caused by Kirkendall effect is in progress and is used to optimize mechanical properties of materials. In this paper the multiphase systems with low non-stoichiometry are discussed. It is shown that in such systems the drift velocity can be approximated as constant in each phase and determined by Wagner's integral diffusivity. In this paper the binary in Ni-Ti alloy is discussed; however, the method can be applied to multicomponent systems. The results of the calculations are compared with experimental data.

    2004-12-31

    The petroleum industry has relied in the past mainly on conventional vessel-type separators, which are bulky, heavy and expensive, to process wellhead production of oil-water-gas flow. Economic and operational pressures continue to force the petroleum industry to seek less expensive and more efficient separation alternatives in the form of compact separators. The compact dimensions, smaller footprint and lower weight of compact separators have a potential for cost savings to the industry, especially in offshore and subsea applications. Also, compact separators reduce the inventory of hydrocarbons significantly, which is critical for environmental and safety considerations. This report presents a brief overview of the activities and tasks accomplished during the part July 09, 2003--October 08, 2004, related to the Budget Period I (July 09, 2003--October 08, 2004) of the DOE project titled ''Design and Development of Integrated Compact Multiphase Separation System (CMSS{copyright})''. An executive summary is presented initially followed by the tasks of the current budget period. Then, detailed description of the experimental and modeling investigations are presented. Subsequently, the technical and scientific results of the activities of this project period are presented with discussions. The findings of this investigation are summarized in the ''Conclusions'' section followed by relevant references. The initial phase of the project (Budget Period I--07/09/2003 to 10/08/2004) focuses on the development of additional individual compact separation components, such as the horizontal pipe separator (HPS{copyright}), for obtaining clean oil stream from oil-water mixture, flow conditioning components, such as the helical pipe (HP) and slug damper (SD{copyright}), for dissipating slugs upstream of the compact separators. The project will also design and test an upstream slug generator (SG).

    2003-08-01

    The importance of the separation-individuation process in object relations theory is well known in disciplines of psychology, counseling, and human development. Based on the Separation-Individuation Inventory of Christenson and Wilson, which measures the manifestations of disturbances in this process, a Chinese version of the inventory was developed. For college students Cronbach coefficient alpha was .89, and test-retest reliability over 28 days was .77. The scores of the inventory had positive correlations with both the number of borderline personality characteristics and the Individualism-Collectivism Scale, respectively. Also, the mean score on the inventory of patients diagnosed with borderline personality disorder was significantly higher than that of the two normal control groups (ns = 564). Thus the inventory possessed satisfactory construct validity. Cultural differences regarding the separation-individuation process need to be investigated further. PMID:14563065

    The link between specific personality profiles and a single psychotropic drug of choice is still unclear and only partially explored. The present study compares three groups of male subjects: 85 patients manifesting heroin dependence (age: 30.07 +/- 2.78), 60 patients manifesting cocaine dependence (age: 31.96 +/- 3.1), and 50 healthy subjects from a random population sample (age: 33.25 +/- 1.45). The patients included in the study showed a long-lasting history of dependence on heroin or cocaine, respectively, 5.2 +/- 2.5 years, 4.6 +/- 2.9 years, and were stabilized in treatment, and abstinent, at least 4 weeks at the time of the diagnostic assessment. Heroin addicts (52.90%) were on methadone maintenance treatment. Cocaine addicts (11.60%) were treated with selective serotonin reuptake inhibitors. Personality traits were measured by the Minnesota Multiphasic Personality Inventory (MMPI-2) and Cloninger's Three-dimensional Personality Questionnaire (TPQ). Character and quantification of aggressiveness were measured by the Buss-Durkee Hostility Inventory (BDHI). Heroin-dependent patients (group A) scored significantly higher on hysteria, masculine-feminine and social introversion subscales of the MMPI, and significantly lower on the harm avoidance (HA) subscale of the TPQ than cocaine addicts. In contrast, scores on the MMPI for hypochondria, psychopathic deviance, and paranoia dimensions were more elevated in cocaine addicts than in heroin-dependent patients. Cocaine addicts scored higher than heroin addicts on the "direct" aggressiveness subscale and on the BDHI total score. Cocaine addicts did not differ from healthy controls on harm avoidance (behavioral control). Although cocaine addicts showed more consistent psychopathic deviance and overt aggressiveness than heroin addicts, higher harm avoidance (behavioral control), hypochondria (or worry about their health), and social extroversion may reduce their proneness to overt antisocial behavior and allow

  13. Oscillatory multiphase flow strategy for chemistry and biology.

    2016-07-19

    Continuous multiphase flow strategies are commonly employed for high-throughput parameter screening of physical, chemical, and biological processes as well as continuous preparation of a wide range of fine chemicals and micro/nano particles with processing times up to 10 min. The inter-dependency of mixing and residence times, and their direct correlation with reactor length have limited the adaptation of multiphase flow strategies for studies of processes with relatively long processing times (0.5-24 h). In this frontier article, we describe an oscillatory multiphase flow strategy to decouple mixing and residence times and enable investigation of longer timescale experiments than typically feasible with conventional continuous multiphase flow approaches. We review current oscillatory multiphase flow technologies, provide an overview of the advancements of this relatively new strategy in chemistry and biology, and close with a perspective on future opportunities.

  14. Lagrangian particle model for multiphase flows

    SciTech Connect

    Tartakovsky, Alexandre M.; Ferris, Kim F.; Meakin, Paul

    2009-10-01

    A Lagrangian particle model for multiphase multicomponent fluid flow, based on smoothed particle hydrodynamics (SPH), was developed and used to simulate the flow of an emulsion consisting of bubbles of a non-wetting liquid surrounded by a wetting liquid. In SPH simulations, fluids are represented by sets of particles that are used as discretization points to solve the Navier-Stokes fluid dynamics equations. In the multiphase multicomponent SPH model, a modified van der Waals equation of state is used to close the system of flow equations. The combination of the momentum conservation equation with the van der Waals equation of state results in a particle equation of motion in which the total force acting on each particle consists of many-body repulsive and viscous forces, two-body (particle-particle) attractive forces, and body forces such as gravitational forces. Similarly to molecular dynamics, for a given fluid component the combination of repulsive and attractive forces causes a phase separation. The surface tension at liquid-liquid interfaces is imposed through component dependent attractive forces. The wetting behavior of the fluids is controlled by phase dependent attractive interactions between the fluid particles and stationary particles that represent the solid phase. The dynamics of fluids away from interface is governed by purely hydrodynamic forces. Comparison with analytical solutions for static conditions and relatively simple flows demonstrates the accuracy of the SPH model.

  15. Multiphase complete exchange: A theoretical analysis

    Bokhari, Shahid H.

    1993-01-01

    Complete Exchange requires each of N processors to send a unique message to each of the remaining N-1 processors. For a circuit switched hypercube with N = 2(sub d) processors, the Direct and Standard algorithms for Complete Exchange are optimal for very large and very small message sizes, respectively. For intermediate sizes, a hybrid Multiphase algorithm is better. This carries out Direct exchanges on a set of subcubes whose dimensions are a partition of the integer d. The best such algorithm for a given message size m could hitherto only be found by enumerating all partitions of d. The Multiphase algorithm is analyzed assuming a high performance communication network. It is proved that only algorithms corresponding to equipartitions of d (partitions in which the maximum and minimum elements differ by at most 1) can possibly be optimal. The run times of these algorithms plotted against m form a hull of optimality. It is proved that, although there is an exponential number of partitions, (1) the number of faces on this hull is Theta(square root of d), (2) the hull can be found in theta(square root of d) time, and (3) once it has been found, the optimal algorithm for any given m can be found in Theta(log d) time. These results provide a very fast technique for minimizing communication overhead in many important applications, such as matrix transpose, Fast Fourier transform, and ADI.

    2014-01-01

    For a successful clinical outcome, periodontal regeneration requires the coordinated response of multiple soft and hard tissues (periodontal ligament, gingiva, cementum, and bone) during the wound-healing process. Tissue-engineered constructs for regeneration of the periodontium must be of a complex 3-dimensional shape and adequate size and demonstrate biomechanical stability over time. A critical requirement is the ability to promote the formation of functional periodontal attachment between regenerated alveolar bone, and newly formed cementum on the root surface. This review outlines the current advances in multiphasic scaffold fabrication and how these scaffolds can be combined with cell- and growth factor–based approaches to form tissue-engineered constructs capable of recapitulating the complex temporal and spatial wound-healing events that will lead to predictable periodontal regeneration. This can be achieved through a variety of approaches, with promising strategies characterized by the use of scaffolds that can deliver and stabilize cells capable of cementogenesis onto the root surface, provide biomechanical cues that encourage perpendicular alignment of periodontal fibers to the root surface, and provide osteogenic cues and appropriate space to facilitate bone regeneration. Progress on the development of multiphasic constructs for periodontal tissue engineering is in the early stages of development, and these constructs need to be tested in large animal models and, ultimately, human clinical trials.

    1993-02-01

    The PANDA code is used to build a multiphase equation of state (EOS) table for iron. Separate EOS tables were first constructed for each of the individual phases. The phase diagram and multiphase EOS were then determined from the Helmholtz free energies. The model includes four solid phases ([alpha],[gamma], [delta], and [var epsilon]) and a fluid phase (including the liquid, vapor, and supercritical regions). The model gives good agreement with experimental thermophysical data, static compression data, phase boundaries, and shock-wave measurements. Contributions from thermal electronic excitation, computed from a quantum-statistical-mechanical model, were found to be very important. This EOS covers a wide range of densities (0--1000 g/cm[sup 3]) and temperatures (0--1.2[times]10[sup 7] K). It is also applicable to RHA steel. The new EOS is used in hydrocode simulations of plate impact experiments, a nylon ball impact on steel, and the shaped charge perforation of an RHA plate. The new EOS table can be accessed through the SNL-SESAME library as material number 2150.

This study assesses, the psychological features of the sample of 276 subjects (114 males, 162females) admitted to a unit of Occupational Medicine, using Minnesota Multiphasic Personality Inventory MMPI-2. Increase in score over 65 cut off compared to clinical scales was found out: Hypochondria, Depression, Hysteria, Paranoia and compared to content scale: Anxiety and Health concerns. No significant different resulted between males and females as regards clinical scales. To conclude our date confirm the hypothesis of a remarkable psychic discomfort in subjects complaining about harassment work. This discomfort, in compliance with the date of literature seem to be characterized by depression, anxiety and somatizations. However show a tendency to focus on working problems and a disposition to persecutories tendencies. All the above said characteristics might be due to negative working conditions or they reflect a psychological frailty which made the subjects more vulnerable to working stress. PMID:18700482

  2. Multiphase flows with digital and traditional microfluidics

    Nilsson, Michael A.

    Multi-phase fluid systems are an important concept in fluid mechanics, seen every day in how fluids interact with solids, gases, and other fluids in many industrial, medical, agricultural, and other regimes. In this thesis, the development of a two-dimensional digital microfluidic device is presented, followed by the development of a two-phase microfluidic diagnostic tool designed to simulate sandstone geometries in oil reservoirs. In both instances, it is possible to take advantage of the physics involved in multiphase flows to affect positive outcomes in both. In order to make an effective droplet-based digital microfluidic device, one must be able to precisely control a number of key processes including droplet positioning, motion, coalescence, mixing, and sorting. For planar or open microfluidic devices, many of these processes have yet to be demonstrated. A suitable platform for an open system is a superhydrophobic surface, as suface characteristics are critical. Great efforts have been spent over the last decade developing hydrophobic surfaces exhibiting very large contact angles with water, and which allow for high droplet mobility. We demonstrate that sanding Teflon can produce superhydrophobic surfaces with advancing contact angles of up to 151° and contact angle hysteresis of less than 4°. We use these surfaces to characterize droplet coalescence, mixing, motion, deflection, positioning, and sorting. This research culminates with the presentation of two digital microfluidic devices: a droplet reactor/analyzer and a droplet sorter. As global energy usage increases, maximizing oil recovery from known reserves becomes a crucial multiphase challenge in order to meet the rising demand. This thesis presents the development of a microfluidic sandstone platform capable of quickly and inexpensively testing the performance of fluids with different rheological properties on the recovery of oil. Specifically, these microfluidic devices are utilized to examine how

    The objective of this project was to develop predictive theories for the dispersion and mass transfer coefficients and to measure them in the turbulent fluidization regime, using existing facilities. A second objective was to use our multiphase CFD tools to suggest optimized gasifier designs consistent with aims of Future Gen. We have shown that the kinetic theory based CFD codes correctly compute: (1) Dispersion coefficients; and (2) Mass transfer coefficients. Hence, the kinetic theory based CFD codes can be used for fluidized bed reactor design without any such inputs. We have also suggested a new energy efficient method of gasifying coal and producing electricity using a molten carbonate fuel cell. The principal product of this new scheme is carbon dioxide which can be converted into useful products such as marble, as is done very slowly in nature. We believe this scheme is a lot better than the canceled FutureGen, since the carbon dioxide is safely sequestered.

    1998-12-01

    A software package devised by Loke Inc., a member of Norway`s CorrOcean Group, is routinely calculating multiphase flows from North Sea wells by monitoring only static measurements-pressures, temperatures and other available measurement quantities. A collection of three modeling programs, the software can also control the production mix and set choke values from individual wells for optimum reservoir production. Calculated flows have proven so accurate that operators now have no need for conventional flow meters or dedicated test lines. In a tuning step taken during initial well testing, Loke establishes parameters for the mathematical models in the software. Thereafter, static measurements of pressure and temperature in the producing well or manifold are converted by the software to flow. These predictions are then used to command choke valves to regulate flow. A representation of the measurement and control scheme is shown.

    X-Ray microscopic methods, benefiting from the large penetration depth of X-rays in many materials, enable 3D investigation of a wide variety of samples. This allows for a wide variety of physical, chemical, and biological structures to be seen and explored, in some cases even in real time. Such measurements have lead to insights into paleontology, vulcanology, genetics, and material science. The ability to see and visualize complex systems can provide otherwise unobtainable information on structure, interactions, mechanical behavior, and evolution. The field has, however, led to a massive amount of new, heterogenous, difficult to process data. We present a general, model-free approach for characterizing multiphase 3D systems and show how the method can be applied to experimental X-ray microscopy data to better understand and quantify layer structure in two typical systems: investigation of layered fibers and clay samples.

    Multiphase flow models have been proposed for use in situations which have combined Rayleigh-Taylor (RTI) and Richtmyer-Meshkov (RMI) instabilities. Such an approach work poorly for the case of a heavy to light shock incidence on a developed interface. The physical original of this difficulty is traced to an inadequate model of the interfacial pressure term as it appears in the momentum and turbulence kinetic energy equations. Constraints on the form of a better model from a variety of sources are considered. In this context it is observed that a new constraint on closures arises. This occurs because of the discontinuity within the shock responsible for the RMI. The proposed model (Shock Scattering) is shown to give useful results.

    A multiphase monitoring system employing nuclear techniques is reported, which is aimed to provide a rapid - decision tool in oilfield applications. Liquid phase time variation is monitored employing two large volume BaF2 detectors. The radioisotope source of 22Na is a positron emitter, therefore two antiparallel gammas are produced per decay, and phase flow in pipes is related to the count rate of gamma pulses in coincidence providing information on transient liquid phase during transport. Oil, gas, water fraction measurements were performed at a specialized test station assembled in our laboratory to model a wide range of field operating conditions. The time dependence of the mixed substances is monitored with the two most relevant hydrodynamic parameters, the density (type of the fluid) and the flow rate, in a LabView® environment. Performance of the monitoring system; its limitations and the possibility for further improvements are also provided.

    A general model to treat multicomponent diffusion in multiphase dispersions is presented. The model is based on multicomponent diffusion data and basic thermodynamic data and contains no adjustable parameters. No restriction is placed on the number of components or phases that take part in the calculations, as long as the necessary thermodynamic and kinetic data are available. The new model is implemented into the DICTRA software, which makes use of THERMO-CALC to handle the thermodynamics. The model is applied to carburization of Ni alloys and heat treatment of welded joints between dissimilar materials. In both cases, the diffusion is accompanied by carbide formation or dissolution. A good agreement between experiments and calculations is found, despite the fact that no adjustable parameters are needed.

    An important principle of accounting is that asset inventory needs to be correctly valued to ensure that the financial statements of the institution are accurate. Errors is recording the value of ending inventory in one fiscal year result in errors to published financial statements for that year as well as the subsequent fiscal year. Therefore, it is important that accurate physical counts be periodically taken. It is equally important that any system being used to generate inventory valuation, reordering or management reports be based on consistently accurate on-hand balances. At the foundation of conducting an accurate physical count of an inventory is a comprehensive understanding of the process coupled with a written plan. This article presents a guideline of the physical count processes involved in a traditional double-count approach. PMID:10165241

    The Hanford Site, in southeastern Washington State, has been used extensively to produce nuclear materials for the US strategic defense arsenal by the Department of Energy (DOE) and its predecessors, the US Atomic Energy Commission and the US Energy Research and Development Administration. A large inventory of radioactive and mixed waste has accumulated in 177 buried single- and double shell tanks. Liquid waste recovered from the tanks will be pretreated to separate the low-activity fraction from the high-level and transuranic wastes. Vitrification is the leading option for immobilization of these wastes, expected to produce approximately 550,000 metric tons of Low Activity Waste (LAW) glass. This total tonnage, based on nominal Na{sub 2}O oxide loading of 20% by weight, is destined for disposal in a near-surface facility. Before disposal of the immobilized waste can proceed, the DOE must approve a performance assessment, a document that described the impacts, if any, of the disposal facility on public health and environmental resources. Studies have shown that release rates of radionuclides from the glass waste form by reaction with water determine the impacts of the disposal action more than any other independent parameter. This report describes the latest accomplishments in the development of a computational tool, Subsurface Transport Over Reactive Multiphases (STORM), Version 2, a general, coupled non-isothermal multiphase flow and reactive transport simulator.

    This is the final report of a Laboratory Directed Research and Development (LDRD) project at the Los Alamos National Laboratory (LANL). The objective of the project was to develop a self-sustained research program for advanced computer simulation of industrial reactive multiphase flows. The prototype research problem was a three-phase alumina precipitator used in the Bayer process, a key step in aluminum refining. Accomplishments included the development of an improved reaction mechanism of the alumina precipitation growth process, the development of an efficient methods for handling particle size distribution in multiphase flow simulation codes, the incorporation of precipitation growth and agglomeration kinetics in LANL's CFDLIB multiphase flow code library and the evaluation of multiphase turbulence closure models for bubbly flow simulations.

    A continuum model for multiphase fluid mixture flows through poroelastic media is presented. The basic conservation laws developed via a volume averaging technique are considered. Effects of phasic equilibrated forces are included in the model. Based on the thermodynamics of the multiphase mixture flows, appropriate constitutive equations are formulated. The entropy inequality is exploited, and the method of Lagrangian multiplier is used along with the phasic conservation laws to derive the constitutive equations for the phasic stress tensors, equilibrated stress vectors, and the interactions terms. The special cases of wave propagation in poroelastic media saturated with multiphase fluids, and multiphase flows through porous media, are studied. It is shown that the present theory leads to the extended Darcy’s law and contains, as a special case, Biot’s theory of saturated poroelastic media.

    A gauging system is proposed to enable monitoring of slush density, solid-liquid interface, and slush level as well as its flow rate. It is based on the principle that the electromagnetic radiation mass attenuation coefficient of a multiphase chemical compound is constant for all relative phase concentrations. Results showing the essential constancy of mass attenuation coefficients for single-phase water vapor, liquid water, ice, and multiphase mixtures of water/ice are described.

    The purpose of this analysis is to provide an initial radionuclide inventory (in grams per waste package) and associated uncertainty distributions for use in the Total System Performance Assessment for the License Application (TSPA-LA) in support of the license application for the repository at Yucca Mountain, Nevada. This document is intended for use in postclosure analysis only. Bounding waste stream information and data were collected that capture probable limits. For commercially generated waste, this analysis considers alternative waste stream projections to bound the characteristics of wastes likely to be encountered using arrival scenarios that potentially impact the commercial spent nuclear fuel (CSNF) waste stream. For TSPA-LA, this radionuclide inventory analysis considers U.S. Department of Energy (DOE) high-level radioactive waste (DHLW) glass and two types of spent nuclear fuel (SNF): CSNF and DOE-owned (DSNF). These wastes are placed in two groups of waste packages: the CSNF waste package and the codisposal waste package (CDSP), which are designated to contain DHLW glass and DSNF, or DHLW glass only. The radionuclide inventory for naval SNF is provided separately in the classified ''Naval Nuclear Propulsion Program Technical Support Document'' for the License Application. As noted previously, the radionuclide inventory data presented here is intended only for TSPA-LA postclosure calculations. It is not applicable to preclosure safety calculations. Safe storage, transportation, and ultimate disposal of these wastes require safety analyses to support the design and licensing of repository equipment and facilities. These analyses will require radionuclide inventories to represent the radioactive source term that must be accommodated during handling, storage and disposition of these wastes. This analysis uses the best available information to identify the radionuclide inventory that is expected at the last year of last emplacement, currently identified as

    An RFID-based mobile handheld inventory management system is proposed in this paper. Differing from the manual inventory management method, the proposed system works on the personal digital assistant (PDA) with an RFID reader. The system identifies electronic tags on the properties and checks the property information in the back-end database server through a ubiquitous wireless network. The system also provides a set of functions to manage the back-end inventory database and assigns different levels of access privilege according to various user categories. In the back-end database server, to prevent improper or illegal accesses, the server not only stores the inventory database and user privilege information, but also keeps track of the user activities in the server including the login and logout time and location, the records of database accessing, and every modification of the tables. Some experimental results are presented to verify the applicability of the integrated RFID-based mobile handheld inventory management system.

    The International Symposium on Cavitation and Multiphase Flow (ISCM 2014) was held in Beijing, China during 18th-21st October, 2014, which was jointly organized by Tsinghua University, Beijing, China and Jiangsu University, Zhenjiang, China. The co-organizer was the State Key Laboratory of Hydroscience and Engineering, Beijing, China. Cavitation and multiphase flow is one of paramount topics of fluid mechanics with many engineering applications covering a broad range of topics, e.g. hydraulic machinery, biomedical engineering, chemical and process industry. In order to improve the performances of engineering facilities (e.g. hydraulic turbines) and to accelerate the development of techniques for medical treatment of serious diseases (e.g. tumors), it is essential to improve our understanding of cavitation and Multiphase Flow. For example, the present development towards the advanced hydrodynamic systems (e.g. space engine, propeller, hydraulic machinery system) often requires that the systems run under cavitating conditions and the risk of cavitation erosion needs to be controlled. The purpose of the ISCM 2014 was to discuss the state-of-the-art cavitation and multiphase flow research and their up-to-date applications, and to foster discussion and exchange of knowledge, and to provide an opportunity for the researchers, engineers and graduate students to report their latest outputs in these fields. Furthermore, the participants were also encouraged to present their work in progress with short lead time and discuss the encountered problems. ISCM 2014 covers all aspects of cavitation and Multiphase Flow, e.g. both fundamental and applied research with a focus on physical insights, numerical modelling and applications in engineering. Some specific topics are: Cavitating and Multiphase Flow in hydroturbines, pumps, propellers etc. Numerical simulation techniques Cavitation and multiphase flow erosion and anti-erosion techniques Measurement techniques for cavitation and

    2013-08-19

    The Department of Energy’s (DOE) National Energy Technology Laboratory (NETL) sponsored a workshop on non-Newtonian multiphase slurry at NETL’s Morgantown campus August 19 and 20, 2013. The objective of this special two-day meeting of 20-30 invited experts from industry, National Labs and academia was to identify and address technical issues associated with handling non-Newtonian multiphase slurries across various facilities managed by DOE. Particular emphasis during this workshop was placed on applications managed by the Office of Environmental Management (EM). The workshop was preceded by two webinars wherein personnel from ORP and NETL provided background information on the Hanford WTP project and discussed the critical design challenges facing this project. In non-Newtonian fluids, viscosity is not constant and exhibits a complex dependence on applied shear stress or deformation. Many applications under EM’s tank farm mission involve non-Newtonian slurries that are multiphase in nature; tank farm storage and handling, slurry transport, and mixing all involve multiphase flow dynamics, which require an improved understanding of the mechanisms responsible for rheological changes in non-Newtonian multiphase slurries (NNMS). To discuss the issues in predicting the behavior of NNMS, the workshop focused on two topic areas: (1) State-of-the-art in non-Newtonian Multiphase Slurry Flow, and (2) Scaling up with Confidence and Ensuring Safe and Reliable Long-Term Operation.

    In the current study, we evaluated the associations between the Minnesota Multiphasic Personality Inventory-2 Restructured Form (MMPI-2-RF; Ben-Porath & Tellegen, 2008) scale scores and the Diagnostic and Statistical Manual of Mental Disorders (5th ed.; DSM-5; American Psychiatric Association, 2013) Section II personality disorder (PD) criterion counts in inpatient and forensic psychiatric samples from The Netherlands using structured clinical interviews to operationalize PDs. The inpatient psychiatric sample included 190 male and female patients and the forensic sample included 162 male psychiatric patients. We conducted correlation and count regression analyses to evaluate the utility of relevant MMPI-2-RF scales in predicting PD criterion count scores. Generally, results from these analyses emerged as conceptually expected and provided evidence that MMPI-2-RF scales can be useful in assessing PDs. At the zero-order level, most hypothesized associations between Section II disorders and MMPI-2-RF scales were supported. Similarly, in the regression analyses, a unique set of predictors emerged for each PD that was generally in line with conceptual expectations. Additionally, the results provided general evidence that PDs can be captured by dimensional psychopathology constructs, which has implications for both DSM-5 Section III specifically and the personality psychopathology literature more broadly.

    The main aim of this study was to investigate longitudinally the personality profile and suicidal ideation and behavior in victims of bullying at work in relation to the evolution of the victimization. Forty-eight victims were evaluated by means of medical and psychological assessment including the Minnesota Multiphasic Personality Inventory-2 (MMPI-2). A follow up session was carried out after an average of 22 months. At first evaluation, the average MMPI-2 personality profile of victims showed abnormal elevations on scales Hs (Hypochondria), D (Depression), Hy (Hysteria), and Pa (Paranoia), which were strikingly similar to that found in previous studies. Furthermore, suicidal ideation and behavior were common among victims. At follow-up, 26 victims reported that the degree of bullying had remained the same or had even worsened, whereas 22 said that the situation had improved or had been resolved. Although there was a trend toward normalization in the MMPI-2 profile for all victims, the profile of the "static" group was still abnormal at follow up. On the contrary, the profile of the "improved" group was entirely within normal range. Suicidal ideation and behavior decreased in all victims, but only to a significant degree in the improved group. Results are discussed in the light of the bullying process. PMID:24547677

    With a multiphase transport (AMPT) model we investigate the relation between the magnitude, fluctuations, and correlations of the initial state spatial anisotropy ɛn and the final state anisotropic flow coefficients vn in Au+Au collisions at √{s NN}=200 GeV. It is found that the relative eccentricity fluctuations in AMPT account for the observed elliptic flow fluctuations, both are in agreement with the elliptic flow fluctuation measurements from the STAR collaboration. In addition, the studies based on two- and multiparticle correlations and event-by-event distributions of the anisotropies suggest that the elliptic-power function is a promising candidate of the underlying probability density function of the event-by-event distributions of ɛn as well as vn. Furthermore, the correlations between different order symmetry planes and harmonics in the initial coordinate space and final state momentum space are presented. Nonzero values of these correlations have been observed. The comparison between our calculations and data will, in the future, shed new insight into the nature of the fluctuations of the quark-gluon plasma produced in heavy ion collisions.

    We investigate groundwater flow near cooling plutons with a computer program that can model multiphase flow, temperatures up to 1200??C, thermal pressurization, and temperature-dependent rock properties. A series of experiments examines the effects of host-rock permeability, size and depth of pluton emplacement, single versus multiple intrusions, the influence of a caprock, and the impact of topographically driven groundwater flow. We also reproduce and evaluate some of the pioneering numerical experiments on flow around plutons. Host-rock permeability is the principal factor influencing fluid circulation and heat transfer in hydrothermal systems. The hottest and most steam-rich systems develop where permeability is of the order of 10-15 m2. Temperatures and life spans of systems decrease with increasing permeability. Conduction-dominated systems, in which permeabilities are ???10-16m2, persist longer but exhibit relatively modest increases in near-surface temperatures relative to ambient conditions. Pluton size, emplacement depth, and initial thermal conditions have less influence on hydrothermal circulation patterns but affect the extent of boiling and duration of hydrothermal systems. Topographically driven groundwater flow can significantly alter hydrothermal circulation; however, a low-permeability caprock effectively decouples the topographically and density-driven systems and stabilizes the mixing interface between them thereby defining a likely ore-forming environment.

    A new technique was developed for multiphase monitoring of organic species in the gasphase and on aerosols with a Proton Transfer Reaction Mass Spectrometer (PTRMS) as the detector. An advantage of the soft ionization technique of the PTRMS, is that it is possible to see the ozonolysis products with little fragmentation. When fragmentation does occur, it is limited to the loss of water from a hydroxyl or carboxyl group, thus facilitating identification. This new system gives detailed information on the chemical composition of organic aerosols, and allows the chemical evolution of condensed organics to be monitored. With this new system it is possible to identify specific chemical compounds in both gas and aerosol phases, instead of the "total organics" which have been reported previously. A series of reactions of ozone with terpenes, beta-caryophyllene and isoprene were preformed in a smog chamber. The secondary organic aerosol and VOCs in the gas phase were measured. Due to the high aerosol concentrations in the smog chamber experiments, air samples could be collected at high time resolution, and it is possible to observe the aging of the aerosol and the gas phase.

    An electrical-impedance tomography (EIT) system has been developed for quantitative measurements of radial phase distribution profiles in two-phase and three-phase vertical column flows. The EIT system is described along with the computer algorithm used for reconstructing phase volume fraction profiles. EIT measurements were validated by comparison with a gamma-densitometry tomography (GDT) system. The EIT system was used to accurately measure average solid volume fractions up to 0.05 in solid-liquid flows, and radial gas volume fraction profiles in gas-liquid flows with gas volume fractions up to 0.15. In both flows, average phase volume fractions and radial volume fraction profiles from GDT and EIT were in good agreement. A minor modification to the formula used to relate conductivity data to phase volume fractions was found to improve agreement between the methods. GDT and EIT were then applied together to simultaneously measure the solid, liquid, and gas radial distributions within several vertical three-phase flows. For average solid volume fractions up to 0.30, the gas distribution for each gas flow rate was approximately independent of the amount of solids in the column. Measurements made with this EIT system demonstrate that EIT may be used successfully for noninvasive, quantitative measurements of dispersed multiphase flows.

    The aim of the study was to find whether there is an association between subjective memory complaint and memory impairment and probable underlying psychological conditions. A total of 90 patients with subjective memory complaint enrolled in this study. Short history and demographic information were obtained and then the patients underwent memory and mental health assessments, using Wechsler Memory Scale (WMS), Hospital Anxiety and Depression Scale (HADS) and Minnesota Multiphasic Personality Inventory (MMPI) test tools. The mean age of the participants was 52.31 ± 17.97. Forty patients out of 90 (44.4%) were male. The prevalence of depression, anxiety and memory impairment was 10%, 12.2%, and 28.8%, respectively. Memory impairment has only shown a significant association with the presence of anxiety disorder according to the HADS findings (P=0.001). Regarding the MMPI, considerable differences were observed in the average grade of hysteria among patients with and without memory impairment: 8.38 ± 2.27 vs. 4.35 ± 1.96. There was also significant statistical association between the average score of depression on the MMPI in patients with and without memory impairment that were 13.7 ± 3.33 and 8.31 ±3.86, (P=0.03). The result of the current study shows that underlying psychological conditions such as anxiety, depression, and histrionic personality are associated with memory impairment. PMID:26024700

    Objective We examined the association between the Minnesota Multiphasic Personality Inventory (MMPI) and all-cause mortality in 4462 middle-aged Vietnam-era veterans. Methods We split the study population into half samples. In each half, we used proportional hazards (Cox) regression to test the 550 MMPI items’ associations with mortality over 15 years. In all participants, we subjected significant (p < .01) items in both halves to principal-components analysis (PCA). We used Cox regression to test whether these components predicted mortality when controlling for other predictors (demographics, cognitive ability, health behaviors, mental/physical health). Results Eighty-nine items were associated with mortality in both half-samples. PCA revealed Neuroticism/Negative Affectivity, Somatic Complaints, Psychotic/Paranoia, and Antisocial components, and a higher-order component, Personal Disturbance. Individually, Neuroticism/Negative Affectivity (HR = 1.55, 95% CI = 1.39,1.72), Somatic Complaints (HR = 1.66; 95% CI = 1.52,1.80), Psychotic/Paranoid (HR = 1.44; 95% CI = 1.32,1.57), Antisocial (HR = 1.79; 95% CI = 1.59,2.01), and Personal Disturbance (HR = 1.74; 95% CI = 1.58,1.91) were associated with risk. Including covariates attenuated these associations (28.4 to 54.5%), though they were still significant. After entering Personal Disturbance into models with each component, Neuroticism/Negative Affectivity and Somatic Complaints were significant, although Neuroticism/Negative Affectivity’s were now protective (HR = 0.73, 95% CI = 0.58,0.92). When the four components were entered together with or without covariates, Somatic Complaints and Antisocial were significant risk factors. Conclusions Somatic Complaints and Personal Disturbance are associated with increased mortality risk. Other components’ effects varied as a function of variables in the model. PMID:23731751

    In the 199os, Hewlett-Packard's PC business was struggling to turn a dollar, despite the company's success in winning market share. By 1997, margins on its PCs were as thin as a silicon wafer, and some product lines hadn't turned a profit since 1993. The problem had everything to do with the PC industry's notoriously short product cycles and brutal product and component price deflation. A common rule of thumb was that the value of a fully assembled PC decreased 1% a week. In such an environment, inventory costs become critical. But not just the inventory costs companies traditionally track, HP found, after a thorough review of the problem. The standard "holding cost of inventory"--the capital and physical costs of inventory--accounted for only about 10% of HP's inventory costs. The greater risks, it turned out, resided in four other, essentially hidden costs, which stemmed from mismatches between demand and supply: Component devaluation costs for components still held in production; Price protection costs incurred when product prices drop on the goods distributors still have on their shelves; Product return costs that have to be absorbed when distributors return and receive refunds on overstock items, and; Obsolescence costs for products still unsold when new models are introduced. By developing metrics to track those costs in a consistent way throughout the PC division, HP has found it can manage its supply chains with much more sophistication. Gone are the days of across-the-board measures such as,"Everyone must cut inventories by 20% by the end of the year," which usually resulted in a flurry of cookie-cutter lean production and just-in-time initiatives. Now, each product group is free to choose the supply chain configuration that best suits its needs. Other companies can follow HP's example. PMID:15768682

    This report outlines scientific issues whose resolution will help advance and define the field of multiphase flow. It presents the findings of four study groups and of a workshop sponsored by the Program on Engineering Physics of the Department of Energy. The reason why multiphase flows are much more difficult to analyze than single phase flows is that the phases assume a large number of complicated configurations. Therefore, it should not be surprising that the understanding of why the phases configure in a certain way is the principal scientific issue. Research is needed which identifies the microphysics controlling the organization of the phases, which develops physical models for the resultant multi-scale interactions and which tests their validity in integrative experiments/theories that look at the behavior of a system. New experimental techniques and recently developed direct numerical simulations will play important roles in this endeavor. In gas-liquid flows a top priority is to develop an understanding of why the liquid phase in quasi fully-developed pipe flow changes from one configuration to another. Mixing flows offer a more complicated situation in which several patterns can exist at the same time. They introduce new physical challenges. A second priority is to provide a quantitative description of the phase distribution for selected fully-developed flows and for simple mixing flows (that could include heat transfer and phase change). Microphysical problems of interest are identified – including the coupling of molecular and macroscopic behavior that can be observed in many situations and the formation/destruction of interfaces in the coalescence/breakup of drops and bubbles. Solid-fluid flows offer a simpler system in that interfaces are not changing. However, a variety of patterns exist, that depend on the properties of the particles, their concentration and the Reynolds number characterizing the relative velocity. A top priority is the

    The largest uncertainty in future climate predictions is caused by aerosols and clouds and their interaction with radiation (IPCC, 2007). Aerosol particles have multiple impacts on atmospheric properties: response to climate by optical properties, providing cloud condensation nuclei, being a heterogeneous surface for multiphase chemical reactions e.g. as a source for reactive chlorine. Therefore the chlorine partitioning in marine and continental atmospheres was studied during intensive field campaigns at two European Supersites for Atmospheric Aerosol Research: Melpitz (51°32N, 12°54 E; 87 m a.s.l., near Leipzig (D), Spindler et al., 2004) and Mace Head (53°19 N, 9°54 W; ~10 m a.s.l., near Galway (IR); O`Connor et al., 2008). Hydrochloric acid (HCl), nitric acid (HNO3) and other gaseous species as well after diffusion based separation particulate matter components (e.g., Na, Cl, nitrate, sulphate and others) were determined simultaneously by a denuder-steam chamber-IC-system with a time resolution of 30 min; limit of quantification: 10 ng m-3 (air flow 10 l min-1; Acker et al., 2005). Numerous other atmospheric components (in gas and particulate phase) as well meteorological parameters were determined. Assuming Na to be only of sea-salt origin, the (mass) Na/Cl ratio found in sea water (Rsea = 0.56) is used for calculation of the degree in chlorine loss in particulate matter: Clloss=1-Rsea/Rsample. In Mace Head to a significant extent (~ 20%), sea salt already is depleted in Cl in air masses originate exclusive from the clean marine sector, mainly caused by HCl formation during heterogeneous sulphate formation. In continental influenced air masses a higher degree in Clloss (~ 46%) was found due to additional acid replacement by nitric acid. In air masses arriving Melpitz a very high loss in chlorine has been observed in the aerosol (~ 83%), not showing a significant dependency from the air mass sector and transport percentage above continent.

    1993-05-01

    The US Department of Energy, through the Yucca Mountain Site Characterization Project Office, has designated the Yucca Mountain site in Nevada for detailed study as the candidate US geologic repository for spent nuclear fuel and high-level radioactive waste. Site characterization will determine the suitability of the Yucca Mountain site for the potential waste repository. If the site is determined suitable, subsequent studies and characterization will be conducted to obtain authorization from the Nuclear Regulatory Commission to construct the potential waste repository. A principal component of the characterization and licensing processes involves numerically predicting the thermal and hydrologic response of the subsurface environment of the Yucca Mountain site to the potential repository over a 10,000-year period. The thermal and hydrologic response of the subsurface environment to the repository is anticipated to include complex processes of countercurrent vapor and liquid migration, multiple-phase heat transfer, multiple-phase transport, and geochemical reactions. Numerical simulators based on mathematical descriptions of these subsurface phenomena are required to make numerical predictions of the thermal and hydrologic response of the Yucca Mountain subsurface environment The engineering simulator called the Multiphase Subsurface Transport Simulator (MSTS) was developed at the request of the Yucca Mountain Site Characterization Project Office to produce numerical predictions of subsurface flow and transport phenomena at the potential Yucca Mountain site. This document delineates the design architecture and describes the specific computational algorithms that compose MSTS. Details for using MSTS and sample problems are given in the {open_quotes}User`s Guide and Reference{close_quotes} companion document.

  19. Viscous and gravitational fingering in multiphase compositional and compressible flow

    NASA Astrophysics Data System (ADS)

    Moortgat, Joachim

    2016-03-01

    Viscous and gravitational fingering refer to flow instabilities in porous media that are triggered by adverse mobility or density ratios, respectively. These instabilities have been studied extensively in the past for (1) single-phase flow (e.g., contaminant transport in groundwater, first-contact-miscible displacement of oil by gas in hydrocarbon production), and (2) multi-phase immiscible and incompressible flow (e.g., water-alternating-gas (WAG) injection in oil reservoirs). Fingering in multiphase compositional and compressible flow has received much less attention, perhaps due to its high computational complexity. However, many important subsurface processes involve multiple phases that exchange species. Examples are carbon sequestration in saline aquifers and enhanced oil recovery (EOR) by gas or WAG injection below the minimum miscibility pressure. In multiphase flow, relative permeabilities affect the mobility contrast for a given viscosity ratio. Phase behavior can also change local fluid properties, which can either enhance or mitigate viscous and gravitational instabilities. This work presents a detailed study of fingering behavior in compositional multiphase flow in two and three dimensions and considers the effects of (1) Fickian diffusion, (2) mechanical dispersion, (3) flow rates, (4) domain size and geometry, (5) formation heterogeneities, (6) gravity, and (7) relative permeabilities. Results show that fingering in compositional multiphase flow is profoundly different from miscible conditions and upscaling techniques used for the latter case are unlikely to be generalizable to the former.

  20. The cognitive, behavioral, and personality profiles of a male monozygotic triplet set discordant for sexual orientation.

    PubMed

    Hershberger, Scott L; Segal, Nancy L

    2004-10-01

    The neurohormonal theory of sexual orientation proposes that homosexual men and homosexual women are exposed prenatally to a hormonal environment that is similar to that of the other sex. Prenatal exposure to an opposite-sex hormonal environment may lead the nervous system to develop in a manner consistent with the opposite sex. If this cross-sex exposure occurs, one prediction would be that the cognitive ability profile of homosexual men would be similar to that of heterosexual women. This study examined a set of male monozygotic triplets, aged 21 years, discordant for sexual orientation: 2 of the triplets were heterosexual, 1 was homosexual. The triplets were administered measures of 23 domains of cognitive ability, as well as measures of sexual orientation and masculinity/femininity. On the measures of cognitive ability, the triplets performed similarly, yet consistent differences were found between the 2 heterosexual triplets and the 1 homosexual cotriplet. Differences having the same pattern were found for the number of Schafer homosexuality signs on the Rorschach, and on a homosexuality scale derived from items on the Minnesota Multiphasic Personality Inventory--2 (MMPI-2). Responses from the homosexual triplet were in a more feminine direction than responses from his 2 heterosexual cotriplets on measures of masculinity-femininity, which included measures derived from Rorschach responses, the MMPI-2 Masculinity-Femininity scale, the Bem Sex Role Inventory, and the Boyhood Gender Conformity Scale. Responses to the 16 Personality Factor Questionnaire also distinguished the 1 homosexual triplet from the 2 heterosexual cotriplets. These findings support the view that the prenatal hormonal environment may have enduring effects on selected behavioral traits. PMID:15305120

    The present study explores how parents' personality clusters relate to their eating disordered daughters' personality and psychopathology. Mothers and fathers were tested with the Temperament Character Inventory. Their daughters were assessed with the following: Temperament and Character Inventory, Eating Disorder Inventory-2, Symptom Checklist-90, Parental Bonding Instrument, Attachment Style Questionnaire, and Family Assessment Device. Daughters' personality traits and psychopathology scores were compared between clusters. Daughters' features were related to those of their parents. Explosive/adventurous mothers were found to relate to their daughters' borderline personality profile and more severe interoceptive awareness. Mothers' immaturity was correlated to their daughters' higher character immaturity, inadequacy, and depressive feelings. Fathers who were explosive/methodic correlated with their daughters' character immaturity, severe eating, and general psychopathology. Fathers' character immaturity only marginally related to their daughters' specific features. Both parents' temperament clusters and mothers' character clusters related to patients' personality and eating psychopathology. The cluster approach to personality-related dynamics of families with an individual affected by an eating disorder expands the knowledge on the relationship between parents' characteristics and daughters' illness, suggesting complex and unique relationships correlating parents' personality traits to their daughters' disorder.

  6. Phase-field modeling of multi-phase solidification

    2002-08-01

    A phase-field model for a general class of multi-phase metallic alloys is now proposed which describes both multi-phase solidification phenomena as well as polycrystalline grain structures. The model serves as a computational method to simulate the motion and kinetics of multiple phase boundaries and enables the visualization of the diffusion processes and of the phase transitions in multi-phase systems. Numerical simulations are presented which illustrate the capability of the phase-field model to recover a variety of complex experimental growth structures. In particular, the phase-field model can be used to simulate microstructure evolutions in eutectic, peritectic and monotectic alloys. In addition, polycrystalline grain structures with effects such as wetting, grain growth, symmetry properties of adjacent triple junctions in thin film samples and stability criteria at multiple junctions are described by phase-field simulations.

    The appearance of gas pockets has an obvious impact on the performance of the rotodynamic multiphase pump. In order to study the formation of gas pockets in the pump and its effects on pump's performance, the unsteady numerical simulation and the visualization experiments were done to investigate gas pockets in a three-stage rotodynamic multiphase pump developed by authors. Meanwhile, the mixture of water and air was selected as the medium. According to the distributions of pressure, gas volume fraction and velocity vector in three compression cells in unsteady flow process, the process of the formation of gas pockets in the pump were analysed generally. The visualization experiments were used to verify the validity of the numerical simulation. The results will be benefit for the hydraulic design of the compression cell of rotodynamic multiphase pump.

  8. A Cell-Centered Multiphase ALE Scheme With Structural Coupling

    SciTech Connect

    Dunn, Timothy Alan

    2012-04-16

    A novel computational scheme has been developed for simulating compressible multiphase flows interacting with solid structures. The multiphase fluid is computed using a Godunov-type finite-volume method. This has been extended to allow computations on moving meshes using a direct arbitrary-Eulerian- Lagrangian (ALE) scheme. The method has been implemented within a Lagrangian hydrocode, which allows modeling the interaction with Lagrangian structural regions. Although the above scheme is general enough for use on many applications, the ultimate goal of the research is the simulation of heterogeneous energetic material, such as explosives or propellants. The method is powerful enough for application to all stages of the problem, including the initial burning of the material, the propagation of blast waves, and interaction with surrounding structures. The method has been tested on a number of canonical multiphase tests as well as fluid-structure interaction problems.

    This is the final report of a proposed three-year, Laboratory-Directed Research and Development (LDRD) project at the Los Alamos National Laboratory (LANL). The project was terminated after the first year due to changes in funding priorities. The objective of the project was to develop a self-sustained research program for advanced computer simulation of industrial reactive multiphase flows. The prototype research problem was a three-phase alumina precipitator used in the Bayer process, a key step in aluminum refining. Accomplishments in the first year included the development of an improved reaction mechanism of the alumina precipitation growth process, the development of an efficient method for handling particle size distribution in multiphase flow simulation codes and finally the incorporation of precipitation growth and agglomeration kinetics in LANL`s CFDLIB multiphase flow code library.

    This paper presents the acceleration of multi-phase smoothed particle hydrodynamics (SPH) using a graphics processing unit (GPU) enabling large numbers of particles (10-20 million) to be simulated on just a single GPU card. With novel hardware architectures such as a GPU, the optimum approach to implement a multi-phase scheme presents some new challenges. Many more particles must be included in the calculation and there are very different speeds of sound in each phase with the largest speed of sound determining the time step. This requires efficient computation. To take full advantage of the hardware acceleration provided by a single GPU for a multi-phase simulation, four different algorithms are investigated: conditional statements, binary operators, separate particle lists and an intermediate global function. Runtime results show that the optimum approach needs to employ separate cell and neighbour lists for each phase. The profiler shows that this approach leads to a reduction in both memory transactions and arithmetic operations giving significant runtime gains. The four different algorithms are compared to the efficiency of the optimised single-phase GPU code, DualSPHysics, for 2-D and 3-D simulations which indicate that the multi-phase functionality has a significant computational overhead. A comparison with an optimised CPU code shows a speed up of an order of magnitude over an OpenMP simulation with 8 threads and two orders of magnitude over a single thread simulation. A demonstration of the multi-phase SPH GPU code is provided by a 3-D dam break case impacting an obstacle. This shows better agreement with experimental results than an equivalent single-phase code. The multi-phase GPU code enables a convergence study to be undertaken on a single GPU with a large number of particles that otherwise would have required large high performance computing resources.

  12. Development of Next Generation Multiphase Pipe Flow Prediction Tools

    Cem Sarica; Holden Zhang

    2006-05-31

    The developments of oil and gas fields in deep waters (5000 ft and more) will become more common in the future. It is inevitable that production systems will operate under multiphase flow conditions (simultaneous flow of gas, oil and water possibly along with sand, hydrates, and waxes). Multiphase flow prediction tools are essential for every phase of hydrocarbon recovery from design to operation. Recovery from deep-waters poses special challenges and requires accurate multiphase flow predictive tools for several applications, including the design and diagnostics of the production systems, separation of phases in horizontal wells, and multiphase separation (topside, seabed or bottom-hole). It is crucial for any multiphase separation technique, either at topside, seabed or bottom-hole, to know inlet conditions such as flow rates, flow patterns, and volume fractions of gas, oil and water coming into the separation devices. Therefore, the development of a new generation of multiphase flow predictive tools is needed. The overall objective of the proposed study is to develop a unified model for gas-oil-water three-phase flow in wells, flow lines, and pipelines to predict flow characteristics such as flow patterns, phase distributions, and pressure gradient encountered during petroleum production at different flow conditions (pipe diameter and inclination, fluid properties and flow rates). In the current multiphase modeling approach, flow pattern and flow behavior (pressure gradient and phase fractions) prediction modeling are separated. Thus, different models based on different physics are employed, causing inaccuracies and discontinuities. Moreover, oil and water are treated as a pseudo single phase, ignoring the distinct characteristics of both oil and water, and often resulting in inaccurate design that leads to operational problems. In this study, a new model is being developed through a theoretical and experimental study employing a revolutionary approach. The

    As part of the Idaho National Laboratory's (INL's) Secure Energy Initiative, the INL is performing research in areas that are vital to ensuring clean, secure energy supplies for the future. The INL Hybrid Energy Systems Testing (HYTEST) Laboratory is being established to develop and test hybrid energy systems with the principal objective to safeguard U.S. Energy Security by reducing dependence on foreign petroleum. HYTEST involves producing liquid fuels in a Hybrid Energy System (HES) by integrating carbon-based (i.e., bio-mass, oil-shale, etc.) with non-carbon based energy sources (i.e., wind energy, hydro, geothermal, nuclear, etc.). Advances in process development, control and modeling are the unifying vision for HES. This paper describes new modeling tools and methodologies to simulate advanced energy processes. Needs are emerging that require advanced computational modeling of multiphase reacting systems in the energy arena, driven by the 2007 Energy Independence and Security Act, which requires production of 36 billion gal/yr of biofuels by 2022, with 21 billion gal of this as advanced biofuels. Advanced biofuels derived from microalgal biomass have the potential to help achieve the 21 billion gal mandate, as well as reduce greenhouse gas emissions. Production of biofuels from microalgae is receiving considerable interest due to their potentially high oil yields (around 600 gal/acre). Microalgae have a high lipid content (up to 50%) and grow 10 to 100 times faster than terrestrial plants. The use of environmentally friendly alternatives to solvents and reagents commonly employed in reaction and phase separation processes is being explored. This is accomplished through the use of hydrothermal technologies, which are chemical and physical transformations in high-temperature (200-600 C), high-pressure (5-40 MPa) liquid or supercritical water. Figure 1 shows a simplified diagram of the production of biofuels from algae. Hydrothermal processing has significant

    Two issues pertinent to the DSM-5 proposal for personality pathology, the recovery of DSM-IV personality disorders (PDs) by proposed DSM-5 traits and the validity of the proposed DSM-5 hybrid model which incorporates both personality pathology symptoms and maladaptive traits, were evaluated in a large undergraduate sample (N = 808). Proposed DSM-5 traits as assessed with the Personality Inventory for DSM-5 explained a substantial proportion of variance in DSM-IV PDs as assessed with the Personality Diagnostic Questionnaire-4+, and trait indicators of the six proposed DSM-5 PDs were mostly specific to those disorders with some exceptions. Regression analyses support the DSM-5 hybrid model in that pathological traits and an indicator of general personality pathology severity provided incremental information about PDs. Findings are discussed in the context of broader issues around the proposed DSM-5 model of personality disorders. PMID:22250660

  11. Relationships between mobbing at work and MMPI-2 personality profile, posttraumatic stress symptoms, and suicidal ideation and behavior.

    PubMed

    Balducci, Cristian; Alfano, Vincenzo; Fraccaroli, Franco

    2009-01-01

    This study investigates the relationships between the experience of mobbing at work and personality traits and symptom patterns as assessed by means of the revised version of the Minnesota Multiphasic Personality Inventory (MMPI-2). Participants were 107 workers who had contacted mental health services because they perceived themselves as victims of mobbing. In line with previous research, the results showed that the MMPI-2 mean profile was characterized by a neurotic component as evidenced by elevations of Scales 1, 2, and 3 and a paranoid component as indicated by elevation of Scale 6. Contrary to previous research, a pattern of positive and significant correlations was found between the frequency of exposure to mobbing behaviors and the MMPI-2 clinical, supplementary, and content scales, including the posttraumatic stress scale. Only about half the participants showed a severity of posttraumatic stress symptoms indicative of a posttraumatic stress disorder. The frequency of exposure to mobbing predicted suicidal ideation and behavior, with depression only partially mediating this relationship. PMID:19297885

    The effects of reward and punishment are different, and there are individual differences in sensitivity to reward and punishment. The purpose of this study was to investigate the effects of reward and punishment on task performance, mood, and autonomic nervous function, along with the interaction with personality. Twenty-one healthy female subjects volunteered for the experiment. The task performance was evaluated by required time and total errors while performing a Wisconsin Card Sorting Test. We assessed their personalities using the Minnesota Multiphasic Personality Inventory (MMPI) questionnaire, and mood states by a profile of mood states. Autonomic nervous function was estimated by a spectral analysis of heart rate variability, baroreflex sensitivity, and blood pressure. Repeated measures analysis of variance (ANOVA) revealed significant interaction of condition x time course on mood and autonomic nervous activity, which would indicate a less stressed state under the rewarding condition, but revealed no significant interaction of condition x time course on the task performance. The interactions with personality were further analyzed by repeated measures ANOVA applying the clinical scales of MMPI as independent variables, and significant interactions of condition x time course x Pt (psychasthenia) on task performance, mood, and blood pressure, were revealed. That is, the high Pt group, whose members tend to be sensitive and prone to worry, showed gradual improvement of task performance under the punishing situation with slight increase in systolic blood pressure, while showed no improvement under the rewarding situation with fatigue sense attenuation. In contrast, the low Pt group, whose members tend to be adaptive and self-confident, showed gradual improvement under the rewarding situation. Therefore, we should carefully choose the strategy of reward or punishment, considering the interaction with personality as well as the context in which it is given. PMID

  18. A single element multiphase compulsator powered railgun systems

    SciTech Connect

    Murthy, S.K.; Weldon, W.F. . Center for Electromechanics)

    1994-01-01

    This paper investigates multiphase railguns (electromagnetic launchers) powered by multiphase compensated pulsed alternators (compulsators). The polyphase system offers several advantages over the single phase system. The multiphase compulsator relaxes the strong dependence between the current pulse width necessary for the railgun and the design parameters of the generator (number of poles, rotor diameter and tip speed) thus allowing the compulsator to be designed for optimum power density and electromechanical energy conversion. The paper examines in particular the two phase system. The authors explore different methods of achieving high acceleration ratios (average to peak) in multiphase railgun systems. Some of the methods analyzed are ramping up the field current of the compulsator to counter the increasing impedance of the gun, using a railgun with varying inductance per unit length (L[prime]), and using an external variable inductor in series with the compulsator. Special attention is devoted to the external series inductor method which uses a rotary flux compressor (rfc). Several concepts to integrate the rfc and the compulsator into a single element device are discussed. Comparison between the state of the art single phase compulsator powered 9 MJ railgun system, currently under fabrication at CEM-UT and a two phase compulsator driven four rail railgun system is also presented.

  20. Multiphase complete exchange on Paragon, SP2 and CS-2

    Bokhari, Shahid H.

    1995-01-01

    The overhead of interprocessor communication is a major factor in limiting the performance of parallel computer systems. The complete exchange is the severest communication pattern in that it requires each processor to send a distinct message to every other processor. This pattern is at the heart of many important parallel applications. On hypercubes, multiphase complete exchange has been developed and shown to provide optimal performance over varying message sizes. Most commercial multicomputer systems do not have a hypercube interconnect. However, they use special purpose hardware and dedicated communication processors to achieve very high performance communication and can be made to emulate the hypercube quite well. Multiphase complete exchange has been implemented on three contemporary parallel architectures: the Intel Paragon, IBM SP2 and Meiko CS-2. The essential features of these machines are described and their basic interprocessor communication overheads are discussed. The performance of multiphase complete exchange is evaluated on each machine. It is shown that the theoretical ideas developed for hypercubes are also applicable in practice to these machines and that multiphase complete exchange can lead to major savings in execution time over traditional solutions.

  1. Applying uncertainty quantification to multiphase flow computational fluid dynamics

    SciTech Connect

    Gel, A; Garg, R; Tong, C; Shahnam, M; Guenther, C

    2013-07-01

    Multiphase computational fluid dynamics plays a major role in design and optimization of fossil fuel based reactors. There is a growing interest in accounting for the influence of uncertainties associated with physical systems to increase the reliability of computational simulation based engineering analysis. The U.S. Department of Energy's National Energy Technology Laboratory (NETL) has recently undertaken an initiative to characterize uncertainties associated with computer simulation of reacting multiphase flows encountered in energy producing systems such as a coal gasifier. The current work presents the preliminary results in applying non-intrusive parametric uncertainty quantification and propagation techniques with NETL's open-source multiphase computational fluid dynamics software MFIX. For this purpose an open-source uncertainty quantification toolkit, PSUADE developed at the Lawrence Livermore National Laboratory (LLNL) has been interfaced with MFIX software. In this study, the sources of uncertainty associated with numerical approximation and model form have been neglected, and only the model input parametric uncertainty with forward propagation has been investigated by constructing a surrogate model based on data-fitted response surface for a multiphase flow demonstration problem. Monte Carlo simulation was employed for forward propagation of the aleatory type input uncertainties. Several insights gained based on the outcome of these simulations are presented such as how inadequate characterization of uncertainties can affect the reliability of the prediction results. Also a global sensitivity study using Sobol' indices was performed to better understand the contribution of input parameters to the variability observed in response variable.

  4. Protecting HAZMAT personnel: A multi-phase process

    SciTech Connect

    Ziegler, P. )

    1993-03-01

    Protecting personnel during hazardous substance releases is a process requiring several integrated elements. Managers must ensure the proper training has occurred and the appropriate personal protective equipment is available. They also must have a thorough understanding of applicable regulations, a well-defined contingency planning program, a ready inventory of air monitoring equipment and provisions for outside assistance. Several regulations apply to an organization that could be responsible for an oil or hazardous substance spill. These have been issued by several regulatory agencies, primarily the US Environmental Protection Agency (EPA) and the Occupational Safety and Health Administration (OSHA). For treatment, storage and disposal facilities and both large and small quantity generators under the jurisdiction of the Resource Conservation and Recovery Act (RCRA), several rules detail emergency planning and training requirements. Title 2 of the Superfund Amendments and Reauthorization Act of 1986 (SARA) established requirements that apply to nearly all industries mainly for emergency incident and chemical use notification. The goal of its provisions, also known as the Emergency Planning and Community Right-to-Know Act (EPCRA), is to enable states and communities to improve chemical safety and better protect public health and the environment.

  5. Exploring the autonomic correlates of personality.

    Shepherd, Daniel; Mulgrew, Joseph; Hautus, Michael J

    2015-12-01

    The aim of this study was to investigate the relationship between personality and resting heart rate variability (HRV) indices. Healthy volunteers (n=106) completed a 240-item Big Five personality inventory, the state/Trait Anxiety inventory, and a ten minute electrocardiographic recording. Time and frequency domain estimates of HRV were derived from the cardiac time series and related to the Big Five dimensions of personality, to personality types extracted from a cluster analysis, and to Trait Anxiety. Frequency domain measures of HRV (HRV-HF, LF/HF) were associated with specific dimensions of personality, but significance was not noted for the time domain measure (STD-RR). Furthermore, distressed personality types exhibited significantly greater autonomic imbalance (LF/HF) than other personality types. However, significance was not noted for the time domain measure (STD-RR). These results can be explained with reference to a contemporary model of neurovisceral integration. PMID:26026396

    2011-08-01

    Twin-screw multiphase pumps are employed increasingly to convey multiphase mixtures of crude oil, accompanying fluids, associated gas and solid particles. They are positive displacement pumps and suitable for handling products containing liquid accompanied by large amounts of gas. Experimental investigations on the conveying characteristic, namely measuring the delivered volume flow as a function of the pressure difference, provide results for selected mixtures. By means of the on hand work, the influence of sorption phenomena occurring due to pressure variations alongside the conveying process on the conveying characteristics of twin-screw pumps delivering mixtures of oil and gases is measured. The employed gases are air and carbon dioxide, which differ strongly in solubility in oil. All experiments are conducted in a closed loop test facility, where oil and gas volume flows are mixed before the inlet and separated after the outlet of the multiphase pump. In order to simulate the influence of the suction side pressure drop in the reservoir on the conveying characteristic, packed beds are employed as oil-filed model. Sorption processes inside of the oil-field model and within the multiphase pump affect the conveying behaviour significantly. The two-phase flow in the inlet and outlet pipe is visualised by means of a capacitance tomography system. Results show that the oil fraction of the total delivered volume flow is decreased due to desorption at the pump inlet. The gas fraction at the pump outlet is further decreased due to absorption. Experimental results are compared to calculated solubilities of the on-hand gases in oil and to the theoretically derived gas volume flow fraction expected at the multiphase pump.

    Otto Kernberg has developed a model of personality and psychological functioning centered on the concept of personality organization. The purpose of this study is to empirically examine the relationships between this model, the five-factor model, and mental health. The Personality Organization Diagnostic Form (Diguer et al., The Personality Organization Diagnostic Form-II (PODF-II), 2001), the NEO Five-Factor Inventory (Costa and McCrae, Revised NEO Personality Inventory (NEO-PI-R) and NEO Five-Factor Inventory (NEO-FFI) Professional Manual. 1992a), and the Health-Sickness Rating Scale (Luborsky, Arch Gen Psychiatry. 1962;7:407-417) were used to assess these constructs. Results show that personality organization and personality factors are distinct but interrelated constructs and that both contribute in similar proportion to mental health. Results also suggest that the integration of personality organization and factors can provide clinicians and researchers with an enriched understanding of psychological functioning. PMID:18043522

    2015-01-01

    A clinician’s effectiveness in treatment depends substantially on his or her attitude toward -- and understanding of -- the patient as a person endowed with self-awareness and the will to direct his or her own future. The assessment of personality in the therapeutic encounter is a crucial foundation for forming an effective working alliance with shared goals. Helping a person to reflect on their personality provides a mirror image of their strengths and weaknesses in adapting to life’s many challenges. The Temperament and Character Inventory (TCI) provides an effective way to describe personality thoroughly and to predict both the positive and negative aspects of health. Strengths and weaknesses in TCI personality traits allow strong predictions of individual differences of all aspects of well-being. Diverse therapeutic techniques, such as diet, exercise, mood self-regulation, meditation, or acts of kindness, influence health and personality development in ways that are largely indistinguishable from one another or from effective allopathic treatments. Hence the development of well-being appears to be the result of activating a synergistic set of mechanisms of well-being, which are expressed as fuller functioning, plasticity, and virtue in adapting to life’s challenges PMID:26052429

    Miscellaneous streams discharging to the soil column on the Hanford Site are subject to requirements of several milestones identified in Consent Order No. DE 9INM-177 (Ecology and DOE 1991). The Plan and Schedule for Disposition and Regulatory Compliance for Miscellaneous Stream (DOE/RL-93-94) provides a plan and schedule for the disposition of miscellaneous streams to satisfy one of the Section 6.0 requirements of the Consent Order. One of the commitments (Activity 6-2.2) established in the plan and schedule is to annually update, the miscellaneous streams inventory. This document constitutes the 1998 revision of the miscellaneous streams inventory. Miscellaneous stream discharges were grouped into four permitting categories (Table 1). The first miscellaneous streams Permit (ST 4508) was issued May 30, 1997, to cover wastewater discharges from hydrotesting, maintenance, and construction activities. The second miscellaneous streams Permit (ST4509) covers discharges from cooling water and condensate discharges. The third permit application for category three waste streams was eliminated by recategorizing waste streams into an existing miscellaneous streams permit or eliminating stream discharges. Elimination of the third categorical permit application was approved by Ecology in January 1997 (Ecology 1997). The fourth permit application, to cover storm water, is due to Ecology in September 1998. Table 1 provides a history of the miscellaneous streams permitting activities.

    We report an investigation into strategies, algorithms, and software tools for document image content extraction and inventory, that is, the location and measurement of regions containing handwriting, machine-printed text, photographs, blank space, etc. We have developed automatically trainable methods, adaptable to many kinds of documents represented as bilevel, greylevel, or color images, that offer a wide range of useful tradeoffs of speed versus accuracy using methods for exact and approximate k-Nearest Neighbor classification. We have adopted a policy of classifying each pixel (rather than regions) by content type: we discuss the motivation and engineering implications of this choice. We describe experiments on a wide variety of document-image and content types, and discuss performance in detail in terms of classification speed, per-pixel classification accuracy, per-page inventory accuracy, and subjective quality of page segmentation. These show that even modest per-pixel classification accuracies (of, e.g., 60-70%) support usefully high recall and precision rates (of, e.g., 80-90%) for retrieval queries of document collections seeking pages that contain a given minimum fraction of a certain type of content.

The overall purpose of this research was to complete the development and validation procedures for the Lao Depression Inventory (LDI). The study consisted of 216 Ethnic Lao refugees. A clinical interview and 164 true/false questions were administered to identify specific items which could identify depression among the Ethnic Lao people. All items were administered in both English and Lao. Overall, 78 of the 164 items differentiated groups of depressed and nondepressed Lao at the .01 level. Results of validation procedures showed that a 30-item scale had an accuracy rate of 89% in identifying the presence of depression in the validation group; the hit-rate for the same items and cutoff was 92% in the cross-validation group. Potential uses of the scale are discussed. PMID:2918451

The objectives of the current work was to examine the multiphase properties for cerium including the dynamic melt boundary and the low-pressure solid-solid phase transition through the critical point. These objectives were addressed by performing plate impact experiment that used multiple experimental configuration including front-surface impact experiments to directly measure transition kinetics, multislug experiments that used the overtake method to measure sound speeds at pressure, and preheat experiments to map out phase boundaries. Preliminary data and analysis obtained for cerium will be presented.

  10. System for measuring multiphase flow using multiple pressure differentials

    DOEpatents

    Fincke, James R.

    2003-01-01

    An improved method and system for measuring a multi-phase flow in a pressure flow meter. An extended throat venturi is used and pressure of the multi-phase flow is measured at three or more positions in the venturi, which define two or more pressure differentials in the flow conduit. The differential pressures are then used to calculate the mass flow of the gas phase, the total mass flow, and the liquid phase. The system for determining the mass flow of the high void fraction fluid flow and the gas flow includes taking into account a pressure drop experienced by the gas phase due to work performed by the gas phase in accelerating the liquid phase.

    The flow of multiple constituents inside a pipe or vessel, known as multiphase flow, is commonly found in many industry branches. The measurement of the individual flow rates in such flow is still a challenge, which usually requires a combination of several sensor types. However, in many applications, especially in industrial process control, it is not necessary to know the absolute flow rate of the respective phases, but rather to continuously monitor flow conditions in order to quickly detect deviations from the desired parameters. Here we show how a simple and low-cost sensor design can achieve this, by using machine-learning techniques to distinguishing the characteristic patterns of oblique laser light scattered at the phase interfaces. The sensor is capable of estimating individual phase fluxes (as well as their changes) in multiphase flows and may be applied to safety applications due to its quick response time.

  12. Fitting of a multiphase equation of state with swarm intelligence

    2015-10-01

    Hydrocode calculations require knowledge of the variation of pressure of a material with density and temperature, which is given by the equation of state. An accurate model needs to account for discontinuities in energy, density and properties of a material across a phase boundary. When generating a multiphase equation of state the modeller attempts to balance the agreement between the available data for compression, expansion and phase boundary location. However, this can prove difficult because minor adjustments in the equation of state for a single phase can have a large impact on the overall phase diagram. This paper describes how combining statistical-mechanics-based condensed matter physics models with a stochastic analysis technique called particle swarm optimisation, yields multiphase equations of state which give good agreement with experiment over a wide range of pressure-temperature space. Aluminium and tin are used as test cases in the proof of principle described in this paper.

  14. Multiphase flow of miscible liquids: jets and drops

    NASA Astrophysics Data System (ADS)

    Walker, Travis W.; Logia, Alison N.; Fuller, Gerald G.

    2015-05-01

    Drops and jets of liquids that are miscible with the surrounding bulk liquid are present in many processes from cleaning surfaces with the aid of liquid soaps to the creation of biocompatible implants for drug delivery. Although the interactions of immiscible drops and jets show similarities to miscible systems, the small, transient interfacial tension associated with miscible systems create distinct outcomes such as intricate droplet shapes and breakup resistant jets. Experiments have been conducted to understand several basic multiphase flow problems involving miscible liquids. Using high-speed imaging of the morphological evolution of the flows, we have been able to show that these processes are controlled by interfacial tensions. Further multiphase flows include investigating miscible jets, which allow the creation of fibers from inelastic materials that are otherwise difficult to process due to capillary breakup. This work shows that stabilization from the diminishing interfacial tensions of the miscible jets allows various elongated morphologies to be formed.

The conditions allowing for linear (in space) transformation of the elastic compliances are also examined.

  17. Toward an improved understanding of multiphase flow in porous media

    NASA Astrophysics Data System (ADS)

    Muccino, Julia C.; Gray, William G.; Ferrand, Lin A.

    1998-08-01

    Physical description of multiphase flow in porous media ideally should be based on conservation principles. In practice, however, Darcy's law is employed as the foundation of multiphase flow studies. Darcy's law is an empirical surrogate for momentum conservation based on data obtained from experimental study of one-dimensional single-phase flow. In its original form [Darcy, 1856], Darcy's law contained a single, constant coefficient that depended on the properties of the medium. Since 1856, Darcy's relation has been heuristically and progressively altered by allowing this coefficient to be a spatially dependent, nonlinear function of fluid and solid phase properties, particularly of the quantities of these phases within the flow system. The shortcoming of this approach is that the governing flow equation is obtained by enhancing a simple empirical coefficient with complex functional dependencies rather than by simplifying general conservation principles. As a result, some of the important physical phenomena are not properly accounted for. Also, some assumptions intrinsic to the equations are overlooked, making accurate simulation more of an art than an entirely scientific exercise. A more general and more theoretically appealing approach to the derivation of conservation principles for multiphase flow has been evolving over the last 30 years. This approach employs a mathematical procedure for deriving conservation principles at the length scale of interest, followed by imposition of thermodynamic constraints to restrict the generality of these expressions. The product of this approach is a set of balance equations that provides a framework in which the assumptions inherent in a hypothesized model of multiphase flow are clearly stated. Requirements for more comprehensive and physically complete models can then be specified.

    This paper describes the use of an Eulerian Dispersed Phase (EDP) model to simulate the water injected from the flame deflector and its interaction with supersonic rocket exhaust from a proposed Space Launch System (SLS) vehicle. The Eulerian formulation, as part of the multi-phase framework, is described. The simulations show that water cooling is only effective over the region under the liquid engines. Likewise, the water injection provides only minor effects over the surface area under the solid engines.

    1994-08-01

    McCrae and Costa since 1986 have proferred a five-factor personality model as a lingua franca among different psychometric test users, and they suggest that their operationalization of the five-factor model, the NEO Personality Inventory, may also be useful in the clinical assessment of the abnormal personality. The present study examined the inventory and its relationship to the 11 personality disorders of Axis II of DSM-III-R in a sample of 180 adults. Correlational multivariate analyses appear to indicate a limited usefulness of the five-factor model in the understanding of personality disorders, and four major objections are offered. Further research with clinical samples, other models of personality, and other measures of personality disorders are encouraged. PMID:7984716

    Multiphase pumping is essentially a means of adding energy to the unprocessed effluent which enables the liquid and gas mixture to be transported over a long distances without prior separation. A reduction, consolidation, or elimination of the production infrastructure, such as separation equipments and offshore platforms can be developed more economically. Also it successfully lowed the backpressure of wells, revived dead wells and improved the production and efficiency of oilfield. This paper reviews the issues related to indoor performance test and an oilfield application of the helico-axial multiphase pump designed by China University of Petroleum (Beijing). Pump specification and its hydraulic design are given. Results of performance testing under different condition, such as operational speed and gas volume fraction (GVF) etc are presented. Experimental studies on combination of theoretical analysis showed the multiphase pump satisfies the similitude rule, which can be used in the development of new MPP design and performance prediction. Test results showed that rising the rotation speed and suction pressure could better its performance, pressure boost improved, high efficiency zone expanding and the flow rate related to the optimum working condition increased. The pump worked unstable as GVF increased to a certain extent and slip occurred between two phases in the pump, creating surging and gas lock at a high GVF. A case of application in Nanyang oilfield is also studied.

    Wilson, Dennis; Granier, John; Johnson, Richard; Littrell, Donald

    2015-06-01

    This paper describes a new class of reactive multiphase blast explosives (RMBX) and characterization of their blast characteristics. These RMBXs are non-ideal explosive compositions of perfluoropolyether (PFPE), nano aluminum, and a micron-size high-density reactive metal - Tantalum, Zirconium, or Zinc in mass loadings of 66 to 83 percent. Unlike high explosives, these PFPE-metal compositions release energy via a fast self-oxidized combustion wave (rather than a true self-sustaining detonation) that is shock dependent, and can be overdriven to control energy release rate. The term ``reactive multiphase blast'' refers to the post-dispersion blast behavior: multiphase in that there are a gas phase that imparts pressure and a solid (particulate) phase that imparts momentum; and reactive in that the hot metal particles react with atmospheric oxygen and the explosive gas products to give an extended pressure pulse. The RMBX formulations were tested in two spherical core-shell geometries - an RMBX shell exploded by a high explosive core, and an RMBX core imploded by a high explosive shell. The fireball and blast characteristics were compared to a C-4 baseline charge.

    2009-04-15

    A mathematical model is proposed to describe the multiphase flow in a dense-medium cyclone (DMC). In this model, the volume of fluid multiphase model is first used to determine the shape and position of the air core, and then the mixture multiphase model is employed to describe the flow of the dense medium (comprising finely ground magnetite in water) and the air core, where the turbulence is described by the Reynolds stress model. The results of fluid flow are finally used in the simulation of coal particle flow described by the stochastic Lagrangian particle tracking model. The validity of the proposed approach is verified by the reasonably good agreement between the measured and predicted results under different conditions. The flow features in a DMC are then examined in terms of factors such as flow field, pressure drop, particle trajectories, and separation efficiency. The results are used to explain the key characteristics of flow in DMCs, such as the origin of a short-circuit flow, the flow pattern, and the motion of coal particles. Moreover, the so-called surging phenomenon is examined in relation to the instability of fluid flow. The model offers a convenient method to investigate the effects of variables related to geometrical and operational conditions on the performance of DMCs.

    Releases of petroleum product such as gasoline and diesel fuels from normal operating practices to aquifers are common. The costs to remediate these releases can run in the billions of dollars. Solutions to remediate these releases usually consist of some form of multiphase (air, water, oil) fluid movement, whether it be a multiphase high vacuum extraction system, bioslurping, groundwater pump and treat system, an air sparging system, a soil vapor extraction system, a free product recovery system, bioremediation or the like. The software being tested in Test Drive, Multiphase Organic Vacuum Enhanced Recovery Simulator (MOVER) is a computer simulation tool that will give the practitioner the ability to design high vacuum enhanced multiple phase recovery systems and bioslurping systems, which are often the low cost effective remediation approach. It will also allow for the comparison of various proposed remediation approaches and technologies so the best solution can be chosen for a site. This is a key competitive advantage to translate conceptual ideas into winning bids.

    Multiphase Mo silicide alloys containing T2 (Mo{sub 5}SiB{sub 2}), Mo{sub 3}Si and Mo phases where prepared by both melting and casting (M and C) and powder metallurgical (PM) processes. Glassy phases are observed in PM materials but not in M and C materials. Microstructural studies indicate that the primary phase is Mo-rich solid solution in alloys containing {le}(9.4Si+13.8B, at. %) and T2 in alloys with {ge}(9.8Si+14.6B). An eutectic composition is estimated to be close to Mo-9.6Si-14.2B. The mechanical properties of multiphase silicide alloys were determined by hardness, tensile and bending tests at room temperature. The multiphase alloy MSB-18 (Mo-9.4Si-13.8B) possesses a flexure strength distinctly higher than that of MoSi{sub 2} and other Mo{sub 5}Si{sub 3} silicide alloys containing no Mo particles. Also, MSB-18 is tougher than MoSi{sub 2} by a factor of 4.

Results from a series of projects to obtain pipeline data in the field, collect operating pipeline data, perform key laboratory experiments at prototypical conditions (large pipe size and high gas density), and to develop and recommend design methods over the past several years have been synthesized to create this report. Technical supervision of these projects has been provided by the Two-Phase Flow Supervisory Committee. This report concisely documents the state of the art in two-phase flow methods, in a manner suitable for use by analysts who want to develop computerized methods to perform the multiphase calculations. This document updates a previous report prepared approximately four years ago (Crowley and Rothe, 1986). Detailed background discussion of the development and selection of the multiphase models is presented in Volume 3 of that reference.

  11. A Virtual Reality Technique for Multi-phase Flows

    2004-04-01

    A virtual reality (VR) technique has been developed to allow user immersion (stereo-graphic rendering, user tracking and object interactivity) in generic unsteady three-dimensional multi-phase flow data sets. This article describes the structure and logic used to design and construct a VR technique that employs a multi-phase flow-field computed a priori as an input (i.e. simulations are conducted beforehand with a researcher's multi-phase CFD code). The input field for this flow visualization is divided into two parts: the Eulerian three-dimensional grid nodes and velocities for the continuous fluid properties (specified using conventional TECLOT data format) and the Lagrangian time-history trajectory files for the dispersed fluid. While tracking the dispersed phase trajectories as animated spheres of adjustable size and number, the continuous-phase flow can be simultaneously rendered with velocity vectors, iso-contour surfaces and planar flood-contour maps of different variables. The geometric and notional view of the combined visualization of both phases is interactively controlled throughout a user session. The resulting technique is demonstrated with a 3-D unsteady data set of Lagrangian particles dispersing in a Eulerian description of a turbulent boundary layer, stemming from a direct numerical simulation of the Navier-Stokes equations.

    We propose a semi-Lagrangian method for multiphase interface tracking. In contrast to previous methods, our method maintains an explicit polygonal mesh, which is reconstructed from an unsigned distance function and an indicator function, to track the interface of arbitrary number of phases. The surface mesh is reconstructed at each step using an efficient multiphase polygonization procedure with precomputed stencils while the distance and indicator function are updated with an accurate semi-Lagrangian path tracing from the meshes of the last step. Furthermore, we provide an adaptive data structure, multiphase distance tree, to accelerate the updating of both the distance function and the indicator function. In addition, the adaptive structure also enables us to contour the distance tree accurately with simple bisection techniques. The major advantage of our method is that it can easily handle topological changes without ambiguities and preserve both the sharp features and the volume well. We will evaluate its efficiency, accuracy and robustness in the results part with several examples. PMID:26353373

    New thermodynamic cycles developed for more efficient low temperature resource utilization can increase the net power production from geothermal resources and sensible waste heat recovery by 20-40%, compared to the traditional organic Rankine cycle. These improved systems consist of a pump, a liquid heat exchanger, a two-phase turbine, and a condenser. The two-phase turbine is used to extract energy from a high speed multiphase fluid and consists of a nozzle and an axial impulse rotor. In order to model and optimize the fluid flow through this part of the system an analysis of two-phase flow through a specially designed convergent-divergent nozzle has to be conducted. To characterize the flow behavior, a quasi-one-dimensional steady-state model of the multiphase fluid flow through a nozzle has been constructed. A numerical code capturing dense compressible multiphase flow under subsonic and supersonic conditions and the coupling between both liquid and gas phases has been developed. The output of the code delivers data vital for the performance optimization of the two-phase nozzle.

    This work presents a brief introduction on the basics of fiber-optical sensors and an overview focused on the applications to measurements in multiphase reactors. The most commonly principle utilized is laser back scattering, which is also the foundation for almost all current probes used in multiphase reactors. The fiber-optical probe techniques in two-phase reactors are more developed than those in three-phase reactors. There are many studies on the measurement of gas holdup using fiber-optical probes in three-phase fluidized beds, but negative interference of particles on probe function was less studied. The interactions between solids and probe tips were less studied because glass beads etc. were always used as the solid phase. The vision probes may be the most promising for simultaneous measurements of gas dispersion and solids suspension in three-phase reactors. Thus, the following techniques of the fiber-optical probes in multiphase reactors should be developed further: (1) online measuring techniques under nearly industrial operating conditions; (2) corresponding signal data processing techniques; (3) joint application with other measuring techniques.

    A recently introduced Level-Set-based Cartesian Grid (LSCG) Characteristics-Based Matching (CBM) method is applied for direct numerical simulation of shock-induced dispersal of solid material. The method incorporates the latest advancements in the level set technology and characteristics-based numerical methods for solution of hyperbolic conservation laws and boundary treatment. The LSCG/CBM provides unique capabilities to simulate complex fluid-solid (particulate) multiphase flows under high-speed flow conditions and taking into account particle-particle elastic and viscoelastic collisions. The particular emphasis of the present study is placed on importance of appropriate modeling of particle-particle collisions, which are demonstrated to crucially influence the global behavior of high-speed multiphase particulate flows. The results of computations reveal the richness and complexity of flow structures in compressible disperse systems, due to dynamic formation of shocks and contact discontinuities, which provide an additional long-range interaction mechanism in dispersed high-speed multiphase flows.

    Micromechanical approaches are frequently employed to monitor local and global field quantities and their evolution under varying mechanical and/or thermal loading scenarios. In this contribution, an overview on important methods is given that are currently used to gain insight into the deformational and failure behaviour of multiphase materials and complex structures. First, techniques to represent material microstructures are reviewed. It is common to either digitise images of real microstructures or generate virtual 2D or 3D microstructures using automated procedures (e.g. Voronoï tessellation) for grain generation and colouring algorithms for phase assignment. While the former method allows to capture exactly all features of the microstructure at hand with respect to its morphological and topological features, the latter method opens up the possibility for parametric studies with respect to the influence of individual microstructure features on the local and global stress and strain response. Several applications of these approaches are presented, comprising low and high strain behaviour of multiphase steels, failure and fracture behaviour of multiphase materials and the evolution of surface roughening of the aluminium top metallisation of semiconductor devices.

    2016-06-28

    Multiphase flow imaging is a very challenging and critical topic in industrial process tomography. In this article, simulation and experimental results of reconstructing the permittivity profile of multiphase material from data collected in electrical capacitance tomography (ECT) are presented. A multiphase narrowband level set algorithm is developed to reconstruct the interfaces between three- or four-phase permittivity values. The level set algorithm is capable of imaging multiphase permittivity by using one set of ECT measurement data, so-called absolute value ECT reconstruction, and this is tested with high-contrast and low-contrast multiphase data. Simulation and experimental results showed the superiority of this algorithm over classical pixel-based image reconstruction methods. The multiphase level set algorithm and absolute ECT reconstruction are presented for the first time, to the best of our knowledge, in this paper and critically evaluated. This article is part of the themed issue 'Supersensing through industrial process tomography'. PMID:27185966

    Background: Addiction is one of the most serious social damages and due to its progressive nature in all aspects, adversely affects people’s physical and psychological health. Hence, this paper investigates the characteristics of drug addicts in a drug rehabilitation center in the city of Isfahan. Methods: In this cross-sectional study conducted in 2012, the population consisted of all addicts that referred to Shefa Drug Rehabilitation Center. A sample of 201 individuals was selected randomly. Two questionnaires were drawn up to collect data; the first questionnaire examined demographic characteristics and the second was the 71-item Minnesota Multiphase Personality Inventory short form. Chi-square test, Fisher’s exact test and Kruskal-Wallis test were used in SPSS20 to analyze the data. Results: Overall, 98% of participants were men, 65.7% were married, and 13.3% were unemployed. Depression and hypomania were respectively the most and the least prevalent disorders among individuals with high-risk psychological profiles of clinical scales respectively. Psychopathic deviation and schizophrenia were seen among the unemployed more than the employed ones. Conclusion: Considering the fact that depression was the most common personality disorder among the addicts participating, it is recommended that this disorder be given priority in investigations in the treatment programs of these patients. In addition, the scales of disorder, schizophrenia, mental infirmity, mental deviation, and paranoia had a significant relationship to aggression, delirium and hallucination, which must be taken into consideration in the treatment of such patients.

    The study examined relations between the 15 scale scores of the Interpersonal Style Inventory (Lorr & Youniss, 1985) and the domain measures of the five-factor model provided by the NEO Personality Inventory (Costa & McCrae, 1985). A sample of 236 college students were administered both inventories. A principal component analysis of the 5 NEO-PI domain scores and the 15 ISI scale scores followed by a Varimax rotation disclosed the expected five higher-order factors. Four factors, Neuroticism, Extraversion, Conscientiousness and Ageeableness, were defined by both NEO and ISI scales. Openness to Experience, however, was represented in the ISI by Independence and Directiveness, which define its Autonomy dimension. Thus, the ISI measures four of the five factors assessed by the NEO-PI. PMID:1573019

    Accurate and reliable multiphase flow measurements are needed for liquid propulsion systems. Existing volumetric flow meters are adequate for flow measurements with well-characterized, clean liquids and gases. However, these technologies are inadequate for multiphase environments, such as cryogenic fluids. Although, properly calibrated turbine flow meters can provide highly accurate and repeatable data, problems are still prevalent with multiphase flows. Limitations are thus placed on the applicability of intrusive turbine flow meters.

  6. On the lattice Boltzmann method for multiphase flows with large density ratios

    An analysis of the lattice Boltzmann (LB) method for multiphase flows with large density ratios is presented. It is shown that for incompressible, multiphase LB methods, the divergence-free condition is not satisfied within the formal accuracy of the LB method, when the density ratio between the two phases is large enough. The discrete differentiation-by-parts rule is responsible for this error. A new multiphase LB method to resolve this issue is proposed.

    Multiphase systems present an imposing challenge from a standpoint of corrosion evaluation and prediction because of the need to synergistically capture the role of important environmental, flow and metallurgical variables and underlying mechanisms of corrosion. This paper focuses on a methodology to model fluid flow in order to assess wall shear stress in multiphase systems. Methods of determining wall shear stress for differing flow regimes are discussed. An experimental setup for multiphase flow and shear stress simulation is also detailed.

    On December 23, 1991, the US Department of Energy, Richland Operations Office (RL) and the Washington State Department of Ecology (Ecology) agreed to adhere to the provisions of the Department of Ecology Consent Order. The Consent Order lists the regulatory milestones for liquid effluent streams at the Hanford Site to comply with the permitting requirements of Washington Administrative Code. The RL provided the US Congress a Plan and Schedule to discontinue disposal of contaminated liquid effluent into the soil column on the Hanford Site. The plan and schedule document contained a strategy for the implementation of alternative treatment and disposal systems. This strategy included prioritizing the streams into two phases. The Phase 1 streams were considered to be higher priority than the Phase 2 streams. The actions recommended for the Phase 1 and 2 streams in the two reports were incorporated in the Hanford Federal Facility Agreement and Consent Order. Miscellaneous Streams are those liquid effluents streams identified within the Consent Order that are discharged to the ground but are not categorized as Phase 1 or Phase 2 Streams. This document consists of an inventory of the liquid effluent streams being discharged into the Hanford soil column.

    A community sample of 262 European American mothers of firstborn 20-month-olds completed a personality inventory and measures of parenting cognitions (knowledge, self-perceptions, and reports about behavior) and was observed in interaction with their children from which measures of parenting practices (language, sensitivity, affection, and play) were independently coded. Factor analyses of the personality inventory replicated extraction of the Five-Factor model of personality (Openness, Neuroticism, Extraversion, Agreeableness, and Conscientiousness). Controlling for sociodemographic characteristics, the five personality factors qua variables and in patterns qua clusters related differently to diverse parenting cognitions and practices, supporting the multidimensional, modular, and specific nature of parenting. Maternal personality in the normal range, a theoretically important but empirically neglected factor in everyday parenting, has meaning in studies of parenting, child development, and family process.

    The focus of the development and application of a soil inventory model as part of the Remediation and Closure Science (RCS) Project managed by PNNL was to develop a probabilistic approach to estimate comprehensive, mass balanced-based contaminant inventories for the Hanford Site post-closure setting. The outcome of this effort was the Hanford Soil Inventory Model (SIM). This document is a user's guide for the Hanford SIM. The principal project requirement for the SIM was to provide comprehensive quantitative estimates of contaminant inventory and its uncertainty for the various liquid waste sites, unplanned releases, and past tank farm leaks as a function of time and location at Hanford. The majority, but not all of these waste sites are in the 200 Areas of Hanford where chemical processing of spent fuel occurred. A computer model capable of performing these calculations and providing satisfactory quantitative output representing a robust description of contaminant inventory and uncertainty for use in other subsequent models was determined to be satisfactory to address the needs of the RCS Project. The ability to use familiar, commercially available software on high-performance personal computers for data input, modeling, and analysis, rather than custom software on a workstation or mainframe computer for modeling, was desired.
