An Empirical Investigation of the Structural Form and Measurement Validity of the Hill Inventory

Blake, Faye W. 08 1900 (has links)
This research began with the Hill Inventory. Cognitive style preference variables were classified as one of following four types: Theoretical Codes, Qualitative Codes, Social-Cultural Codes or Reasoning Modalities. A consumer behavior perspective was then used to form an alternative structure for the Hill Inventory variables. The following three constructs were proposed: Evaluation Codes, Perceptual Codes, and Reasoning Modalities. The purpose of this research was to assess the structural form and measurement validity of the Hill Inventory. Specific steps taken to accomplish this objective included: developing confirmatory factor and structural equation models; using the LISREL software package to analyze the model specifications; and assessing the validity of the questions used to measure the variables. A descriptive research design was used to compare the model specifications. The research instrument consisted of eight statements for each of twenty-eight variables for a total of 224 questions. Five-point response choices were described by the words: often, sometimes, unsure, rarely, or never. The sample consisted of 285 student subjects in marketing classes at a large university. Data analysis began by comparing the distributions of the data to a normal case. Parameter estimates, root mean square residuals and squared multiple correlations then were obtained using the LISREL VI software package. The chi-square statistic was used to test the hypotheses. This statistic was supplemented by the Tucker-Lewis index which used a null model for comparisons. The final step in data analysis was to assess the reliability of the measurements. This study affected the potential usage of the Hill Inventory for consumer behavior research. The major conclusion was that the measurement of the variables must be improved before model parameters can be tested. Specific question sets on the inventory were identified that were most in need of revision.

Total Stress Load Inventory: A Validation Study

Sherck-O'Connor, Robin 12 1900 (has links)
The purpose of this study was to validate a stress inventory which would differentiate between a normative group and a patient population suffering from environmental illness. The hypotheses of this study were: (1) the Total Stress Load Inventory would be predictive in discriminating between clinical ecology patients and a normative group; (2) each section or subscale of the Total Stress Load Inventory would be predictive of psychological, cognitive, nutritional, and/or medical factors.

Validity Scale Elevation in Factor Analysis of the MMPI-168

McGraw, Richard Michael 05 1900 (has links)
In a statistical comparison of orthogonal normalized varimax factor analytic solutions for the MMPI-168 including and excluding invalid protocols of psychiatric inpatients, at least one factor reflection was observed. Factors identified were Psychotic Distortion (Absence of Distress), Somaticism, Depression, Extroversion, Masculinity-Femininity, and Low Morale. Factors obtained, and representative clinical scales, were consistent with those obtained by others in investigations of both abbreviated and standard MMPI forms. Statistical comparison of factors identified by the two analyses indicated congruence. Possible sources of factor distortion were discussed.

Validity of the California Psychological Inventory as a Tool for Sales Selection

Frautschi, Patricia Hinojosa 08 1900 (has links)
The study investigated the predictive validity of the California Psychological Inventory (CPI) as a tool for sales selection. Two analyses were conducted. Study 1 consisted of 20 male home improvement representatives. The average net and gross closing ratios for a six month period were used as the criteria. The results indicted that none of the CPI scales differentiated between poor and good performers when correlated with the secondary criterion of gross closing ratios. These findings were contrary to a previous concurrent validity study. Study 2 investigated month to month retention/separation for 61 home improvement representatives, to determine if the CPI differentiated between short and long term success. Phi coefficients showed no statistical significance between retention/separation and the CPI profile score over time.

The Interpersonal Communication Inventory: a Measure of Social Skills

Armstrong, Betty K. 12 1900 (has links)
The Interpersonal Communication Inventory, a self-report instrument for assessing social skills, was given to undergraduate college students to determine its reliability. Following this administration, other small groups of undergraduates were asked to complete an attraction scale, the Interpersonal Communication Inventory, an assertiveness scale, and a sociometric questionnaire. Results confirmed the Inventory as a reliable instrument, but a stepwise multiple linear regression did not support the hypothesis that the Inventory was a useful predictor of sociometric choice. In addition, Pearson product moment correlations between the Inventory and an assertiveness scale did not confirm the prediction that the two instruments would measure behaviors from different response classes. Definite conclusions could not be stated due to lack of validity data for the Inventory and possible confounding variables.

Differential Scores of Feminists and Traditional Women on the Ego Strength (ES) Scale of the Minnesota Multiphasic Personality Inventory (MMPI)

Logan, Ann Catherine 12 1900 (has links)
Since women in the Women's Rights Movement (Feminists) tend to be educated, career- or goal-oriented, and typically middle-class it was anticipated that these aspects would be reflected in an elevation on the ego strength (Es) scale of the Minnesota Multiphasic Personality Inventory (MMPI). This anticipated elevation was felt to be functionally related not only to career- or goal-oriented behavior and intelligence, but to active participation on an autonomous basis in the Women's Rights Movement as well. Because of the different activities of various Feminist organization, i.e., women's studies programs, consciousness raising, investigations of inequities to women, confrontations with establishment hierarchies, and participation in career and other self-fulfilling activities, it was hypothesized that women who are active Feminists would score significantly higher on the Es scale than a similar group of active women who are not Feminists.

An analysis of the impact of data errors on backorder rates in the F404 engine system

Burson, Patrick A. R. 03 1900 (has links)
Approved for public release; distribution in unlimited. / In the management of the U.S. Naval inventory, data quality is of critical importance. Errors in major inventory databases contribute to increased operational costs, reduced revenue, and loss of confidence in the reliability of the supply system. Maintaining error-free databases is not a realistic objective. Data-quality efforts must be prioritized to ensure that limited resources are allocated to achieve the maximum benefit. This thesis proposes a methodology to assist the Naval Inventory Control Point in the prioritization of its data-quality efforts. By linking data errors to Naval inventory performance metrics, statistical testing is used to identify errors that have the greatest adverse impact on inventory operations. By focusing remediation efforts on errors identified in this manner, the Navy can best use its limited resources devoted to improvement of data quality. Two inventory performance metrics are considered: Supply Material Availability (SMA), an established metric in Naval inventory management; and Backorder Persistence Metric (BPM), which is developed in the thesis. Backorder persistence measures the duration of time that the ratio of backorders to quarterly demand exceeds a threshold value. Both metrics can be used together to target remediation on reducing shortage costs and improving inventory system performance. / Lieutenant Commander, Supply Corps, United States Navy

An Investigation of the Relationships Between the Scoring Rubrics Inventory and the Metacognitive Awareness Inventory as Reported by Secondary School Core-Subject Teachers

Pucheu, Paula Marie 16 May 2008 (has links)
The promise of increased student achievement through educational reform is delivered still-born if teachers do not know how to implement complex instructional practices and sophisticated analysis of student performance. Metacognitive awareness is crucial to the adoption and application of proven educational initiatives. Teachers who successfully implement criterion-referenced assessment instruction, scoring rubrics, transfer to their students the metacognitive knowledge and skills of how to learn. This study is predicated on the research assumptions that metacognition and its attendant skills are critical to the successful implementation of scoring rubrics. A researcher-developed instrument, the Scoring Rubrics Inventory (SRI) and the Metacognitive Awareness Inventory (MAI) were distributed to core-subject teachers from three large public schools in Southwest Louisiana. From a population of sixty-eight (N=68) voluntary participants, eighteen teacher-participants self-reported as high implementers of scoring rubrics, thirty-nine as mid-level implementers and eleven as low-level implementers. From this population, twelve subjects were randomly selected (four high, four mid-level, and four lowlevel implementers) by an outside rater for double-blind observations and interviews. Pearson Product Moment correlations of the SRI and the MAI revealed five significant pairings using an alpha level of .05. The statistical results, coupled with the observation and interview findings from the sample-subjects established the consistency and stability of the Scoring Rubrics Inventory. Further, the totality of the results reported here support the research hypothesis of the study: H1: There is a significant correlation between the metacognitive awareness of secondary school core-subject teachers and the successful implementation of scoring rubrics. The results of the study indicated that secondary school core-subject teachers who successfully implement scoring rubrics possess a metacognitive awareness that transcends professional development training. The findings also suggested that teacher-participants who do not implement scoring rubrics either cannot or lack commitment to the innovation. Implications for teacher educators and school leaders indicated the need to: identify those persons who require additional professional development training; include operational strategies and modeling of successful implementation during training; and maintain a consistent training program in scoring rubrics. Recommendations for future research were offered.

Deriving System Vulnerabilities Using Log Analytics

Higbee, Matthew Somers 01 November 2015 (has links)
System Administrators use many of the same tactics that are implemented by hackers to validate the security of their systems, such as port scanning and vulnerability scanning. Port scanning is slow, and can be highly inaccurate. After a scan is complete, the results of the scan must be cross checked with a vulnerability database to discover if any vulnerabilities are present. While these techniques are useful, they have severe limitations. System Administrators have full access to all of their machines. They should not have to rely exclusively on port scanning them from the outside of their machines to check for vulnerabilities when they have this level of access. This thesis introduces a novel concept for replacing port scanning with a Log File Inventory Management System. This system will be able to automatically build an accurate system inventory using existing log files. This system inventory will then be automatically cross checked with a database of known vulnerabilities in real-time resulting in faster and more accurate vulnerability reporting than is found in traditional port scanning methods.
