Posttraumatic Growth: Behavioral, Cognitive, and Demographic Predictors

Posttraumatic Growth: Behavioral, Cognitive, and Demographic Predictors

Date: August 2011
Creator: Schuettler, Darnell
Description: Recent trauma research argues trauma results in distinct positive and negative consequences, however; many trauma variables positively correlate with both outcomes. This study examined posttraumatic growth (PTG) and post-traumatic stress disorder (PTSD) symptoms as positive and negative trauma outcomes. Behavioral, cognitive, and demographic correlates and predictors were assessed to help clarify differences between the two outcomes. While several behavioral factors were common to both PTG and PTSD symptoms, centrality of event and problem focused coping were the strongest PTG predictors, whereas centrality of event and avoidant coping were the strongest PTSD predictors. These findings indicate while greater incorporation of a trauma/stressful event into one’s identity is a key component of both PTG and PTSD development, behavioral response may be a determining factor between growth or debilitation.

Posttraumatic Stress Disorder as a Differential Diagnosis of Sexually Abused Children: a Survey of Psychologists

Posttraumatic Stress Disorder as a Differential Diagnosis of Sexually Abused Children: a Survey of Psychologists

Date: August 1997
Creator: Gonzalez, Christine
Description: Psychologists' diagnostic choices when the specificity of child sexual abuse in a clinical vignette is varied was examined. The degree to which Posttraumatic Stress Disorder (PTSD) was judged to be a viable diagnostic choice among a set of diagnoses was analyzed under conditions with sexual abuse stated, implied, not stated, and excluded. PTSD was rated as more likely for the stated and implied sexual abuse vignettes than for the not stated and excluded vignettes.

Posttraumatic Stress Disorder in Adolescents with Conduct Disorder: Pre- and Post-Treatment Comparison of Trauma Types

Posttraumatic Stress Disorder in Adolescents with Conduct Disorder: Pre- and Post-Treatment Comparison of Trauma Types

Date: August 1997
Creator: Ovaert, Lynda B.
Description: The purpose of this study was to compare pre- and post-treatment differences in posttraumatic stress disorder (PTSD) symptoms in male adolescents with conduct disorder. The Children's PTSD Inventory and the PTSD Reaction Index were used to diagnose PTSD and determine trauma type (Type I single trauma or Type II recurring trauma). Pre- and post-treatment measures included the PTSD Reaction Index, the Children's Depression Inventory, the State-Trait Anxiety Inventory, the State-Trait Anger Expression Inventory, the Dissociative Experiences Scale, and the Youth Self-Report. The six-week, biweekly group treatment included education, exposure, and cognitive elements. Primary hypotheses that the abused group would statistically differ from the non-abused group in terms of pre- and post-treatment levels of avoidance, dissociation, anger/aggression, self-destructiveness, social problems, and overall levels of PTSD symptoms, were not confirmed. Overall, group therapy participants experienced statistically significant decreases in PTSD symptoms over the course of therapy. Results are discussed in light of clinical implications, recommended cautions given the lack of a robust control group, and directions for future research.

Potential Distribution of an Electrical Source-Sink Combination Along the Axis of an Infinite Cylinder

Potential Distribution of an Electrical Source-Sink Combination Along the Axis of an Infinite Cylinder

Date: 1953
Creator: Parish, Edward R.
Description: In the present paper, an attempt is made to obtain the potential distribution in the case of two such charges, a source-sink combination, located on the axis of a bore hole drilled through an infinite, homogeneous medium.

The potential of coelomocyte chemotaxis as an immune biomarker in the earthworm, Lumbricus terrestris

The potential of coelomocyte chemotaxis as an immune biomarker in the earthworm, Lumbricus terrestris

Access: Use of this item is restricted to the UNT Community.
Date: December 1999
Creator: Mota, Jennifer A.
Description: Coelomocyte migration responses, both random and chemotatic, were examined in the earthworm Lumbricus terrestris. Coelomocyte random migration patterns towards non-stimulatory, non-chemotatic solutions were described. Migration responses to immunostimulatory agents lipopolysaccharides (LPS), N-formly-methionyl-leucyl-phenylalanine (FMLP), sheep erythrocytes, Saccharomyces cerevisiae, Aeromonas hydrophila, Eisenia fetida and Rhabditis pellio were characterized. Chemotaxis was reported to LPS, FMLP, sheep erythrocytes, S. cerivesae and E. fetida. Bio-indicator potential of chemotaxis is discussed relative to variability in migration responses.

Pottery and Tiles of Guanajuato, Mexico

Pottery and Tiles of Guanajuato, Mexico

Date: 1946
Creator: Fincher, Frances Merle
Description: This paper is the result of a study made in Guanajuato, Mexico, in the summer of 1945. It is an attempt to set forth the development of the methods used in making pottery and tiles in this region -- to trace the methods, forms, and motifs from the pre-Conquest period through the Colonial and contemporary periods, to find what changes have come about in the art of making pottery and tiles, and to discover the causes of these changes.

Power-benefit analysis of erasure encoding with redundant routing in sensor networks.

Power-benefit analysis of erasure encoding with redundant routing in sensor networks.

Date: December 2006
Creator: Vishwanathan, Roopa
Description: One of the problems sensor networks face is adversaries corrupting nodes along the path to the base station. One way to reduce the effect of these attacks is multipath routing. This introduces some intrusion-tolerance in the network by way of redundancy but at the cost of a higher power consumption by the sensor nodes. Erasure coding can be applied to this scenario in which the base station can receive a subset of the total data sent and reconstruct the entire message packet at its end. This thesis uses two commonly used encodings and compares their performance with respect to power consumed for unencoded data in multipath routing. It is found that using encoding with multipath routing reduces the power consumption and at the same time enables the user to send reasonably large data sizes. The experiments in this thesis were performed on the Tiny OS platform with the simulations done in TOSSIM and the power measurements were taken in PowerTOSSIM. They were performed on the simple radio model and the lossy radio model provided by Tiny OS. The lossy radio model was simulated with distances of 10 feet, 15 feet and 20 feet between nodes. It was found that by ...

The power of teams: Do self-managing work teams influence managers' perceptions of potency?

The power of teams: Do self-managing work teams influence managers' perceptions of potency?

Date: December 2005
Creator: Hass, Nicolette P.
Description: The present study examined the perceptions of teams and managers on team potency levels as a function of stage of team development. Drawing from the power and influence literature, potency was established as a means by which to assess team's internal dynamics. Stage of team development was separated into four categories including pseudo, potential, real and high performance teams. Archival data included 45 teams and managers gathered from the manufacturing and service industries. Results indicated a significant linear relationship between team perceptions of team potency and stage of team development. Additionally, potency perceptions of teams significantly differentiated between the four stages of team development. Manager perceptions of team potency produced non-significant results. Possible explanations of the results as well as implications for practice and future research are provided.

Powerlessness and the Deferred Gratification Pattern Among Lower and Middle Class Children

Powerlessness and the Deferred Gratification Pattern Among Lower and Middle Class Children

Date: August 1969
Creator: Kelley, Janette
Description: The study attempts to determine the degree of powerlessness and the deferment of gratification among children as measured by instruments designed for this purpose. An effort will be made to test whether the deferred gratification pattern exists in inverse relationship to the feeling of powerlessness among the lower classes; and to determine whether children who feel they are estranged from society have a psychological need for an impulsive release of feelings.
