Formal And Informal Work Group Relationships With Performance: A Moderation Model Using Social Network Analysis, Benjamin R. Knost

Theses and Dissertations

Social networks have recently emerged in the management discipline as a unique way of studying individuals groups in organizations. While traditionally used in the analysis of un-bounded networks, applying social network analysis techniques to bounded work groups and organizational teams has become increasingly popular. Past research has established relationships between in-degree social network centrality and individual performance as well as social network density and overall group performance. This field study, conducted at a military training course, attempted to further refine this social network-performance relationship by modeling characteristics of both the formal and informal work group networks in relation to performance …

Influence Of Organizational Culture On The Relationship Between Psychological Contracts And Organizational Citizenship Behavior, Jennifer M. Carbajal

Theses and Dissertations

The issue of what antecedents of organizational citizenship behavior (OCB) and psychological contracts (PC) employees form with their organization has also been of interest as they have many implications on an employee's extra-role behavior, specifically OCBs. This research investigates the relationship between types of PCs (a) relational and (b) transactional and the propensity to perform (a) altruism and (b) compliance OCB. Furthermore, the influence of organizational culture (OC) dimensions (a) internal orientation and (b) external orientation on this relationship was explored. The results show that transactional PCs were negatively related to both dimensions of OCB. Relational PCs were positively related …

Visual-Spatial & Visual-Motor Function In Pediatric Heart Transplant Recipients, Stephanine Dianne Griffone

Loma Linda University Electronic Theses, Dissertations & Projects

Heart surgery is commonly used to repair congenital heart defects and to perform heart transplantation. The associated hypoxia before or during the surgery may cause damage in the parasaggital area of the cerebral cortex, with resulting difficulty during tasks requiring visual-spatial and visual-motor skills. This study compares the performance of children who received a heart transplant during infancy to that of nonclinical children with no medical complications on three visual-motor measures, three visual-spatial measures, and two computerized visual-spatial tasks - a Block Design Matching task and a Mental Rotation task. The children who received a heart transplant achieved significantly lower …

Pnes: Neuropsychological Impairments & Psychological Symptomatology, Adriana Macias

Loma Linda University Electronic Theses, Dissertations & Projects

The present study utilized a standardized neuropsychological evaluation and self report measures to compare 52 female patients, 18 years of age and older with a video-electroencephalogram (V-EEG) confirmed diagnosis of psychogenic non-epileptic seizures (PNES) (n₁=29) to a group of left temporal lobe epilepsy (L-TLE) demographically matched patients (n₂=23). In an attempt to overcome methodological confounds of previously reported studies, participants were chosen based on stringent exclusion criteria, which barred mixed etiologies. The purpose of this study was to investigate possible differences in neuropsychological functioning, mood, and personality characteristics between individuals with PNES and those with L-TLE. …

Large-Scale Investigation Of The Role Of Trait Activation Theory For Understanding Assessment Center Convergent And Discriminant Validity, Filip Lievens, Christopher S. Chasteen, Eric A. Day, Neil D. Christiansen

Research Collection Lee Kong Chian School Of Business

This study used trait activation theory as a theoretical framework to conduct a large-scale test of the interactionist explanation of the convergent and discriminant validity findings obtained in assessment centers. Trait activation theory specifies the conditions in which cross-situationally consistent and inconsistent candidate performances are likely to occur. Results obtained by aggregating correlations across 30 multitrait-multimethod matrices supported the propositions of trait activation theory, shedding a more positive light on the construct validity puzzle in assessment centers. Overall, convergence among assessment center ratings was better between exercises that provided an opportunity to observe behavior related to the same trait, and …

A Within-Subjects Validation Of A Group-Administered Timeline Followback For Alcohol Use, Eric R. Pedersen, Joseph W. Labrie

Heads Up!

Objective

The current study uses a within-subjects randomized design with the Timeline Followback (TLFB) method administered in groups or to individuals to determine the equivalence of these methods.

Sex Similarities And Differences In Preferences For Short-Term Mates: What, Whether, And Why, Norman P. Li, Douglas T. Kenrick

Research Collection School of Social Sciences

Are there sex differences in criteria for sexual relationships? The answer depends on what question a researcher asks. Data suggest that, whereas the sexes differ in whether they will enter short-term sexual relationships, they are more similar in what they prioritize in partners for such relationships. However, additional data and context of other findings and theory suggest different underlying reasons. In Studies 1 and 2, men and women were given varying "mate budgets" to design short-term mates and were asked whether they would actually mate with constructed partners. Study 3 used a mate-screening paradigm. Whereas women have been found to …

Beneath The Tip Of The Iceberg: A Human Factors Analysis Of General Aviation Accidents In Alaska Versus The Rest Of The United States, Cristy Detwiler, Carla Hackworth, Kali Holcomb, Albert Boquet, Elaine Pfleiderer, Douglas Wiegmann, Scott Shappell

Publications

Historically, general aviation (GA) accidents have been overlooked and their impact under-appreciated when compared with those in the commercial or military sector. Recently however, the Federal Aviation Administration and other governmental and civilian organizations have focused their attention on one piece of this proverbial “iceberg,” that being GA accidents occurring in Alaska. This study examines more than 17,000 GA accidents using the Human Factors Analysis and Classification System. Comparisons of Alaska to the rest of the U.S. (RoUS) included traditional demographic and environmental variables, as well as the human errors committed by aircrews. Overall, categorical differences among unsafe acts (decision …

Perceptions Of Parents, Self, And God As Predictive Of Sympton Severity Among Women Beginning Inpatient Treatment For Eating Disorders, Melissa H. Smith

Theses and Dissertations

The present investigation examined whether perceptions of parents, self, and God among women beginning inpatient treatment for eating disorders was predictive of symptom severity. The sample included 464 women (ages 12 to 56 years) beginning inpatient treatment for eating disorders at a private treatment facility, with the majority being Caucasian. Participants completed study measures as part of an initial battery of assessment measures, and included indices of eating disorder symptomology, parental relationships, self-esteem, and religious well-being. Multiple regression analysis showed perceptions of self and parents to be significant predictors, however perceptions of God failed to predict eating disorder symptom severity. …

Vulnerabilities To Depression, Anxiety And Interpersonal Problems: The Role Of Parental Styles, Schemas And Coping Styles, Daniel Kennedy

Theses and Dissertations

Cognitive theory proposes that maladaptive schemas influence the development of anxious and depressive symptoms and early parental experiences have been proposed to influence schema development. In this current study, measures of depressive and anxious pathology, parenting styles, coping styles and interpersonal problems were administered to 224 undergraduate students. The main purpose the study was to test the cognitive model and the hypothesis that early maladaptive schemas (EMS) as defined by Young (1994) mediate the relationship between parenting styles and anxious and depressive pathology. Results indicated that EMSs do play an important mediational role in relationship to both anxious and depressive …

Differential Item Functioning In Asian-Americans On The Stanford-Binet Standardization Fifth Edition Verbal Subtests, Sheri L. Cardoza

Doctor of Psychology (PsyD)

This research examined the Standardization Edition of the Stanford-Binet, Fifth Edition (SB5), in order to assess the cultural validity of items using an index of differential item functioning (DIF) among Asian American and White/Caucasian American children. Archival data, obtained from the SB5 publisher, was used to determine DIF of items for the 101 Asian American and 200 White/Caucasian American children, ages 4-18. Potential bias was determined through the use of partial correlation. A significant correlation between item and an ethnicity code (with overall ability partialed out) indicated that, in general, one group performed better on a particular item than the …

Exploring The Impact Of Rural And Urban Settings On Therapist Self-Disclosure, Katie Pierson Fruhauff

Doctor of Psychology (PsyD)

There has been a significant amount of research that addresses the topic of therapist self-disclosure. Issues such as what to disclose, when to disclose, the ethics of therapist disclosure, and the benefits and harm of therapist self-disclosure have been debated over the years. How self-disclosure varies among therapists has also been a focus of research. Unlike the area of self-disclosure, research on rural practice is a new and expanding field of research and there is great need for more research in this area. The hypothesis of this study proposes that therapist self-disclosure varies by setting; that rural therapists are more …

Grey Parrot (Psittacus Erithacus) Numerical Abilities: Addition And Further Experiments On A Zero-Like Concept, Irene M. Pepperberg

Sentience Collection

A Grey parrot (Psittacus erithacus), able to quantify 6 or fewer item sets (including heterogeneous subsets) by using English labels (I. M. Pepperberg, 1994), was tested on addition of quantities involving 0–6. He was, without explicit training, asked, “How many total X?” for 2 sequentially presented collections (e.g., of variously sized jelly beans or nuts) and required to answer with a vocal English number label. His accuracy suggested (a) that his addition abilities are comparable to those of nonhuman primates and young children, (b) some limits as to his correlation of “none” and the concept of zero, and (c) a …

Depression Prevention For Early Adolescent Girls: A Pilot Study Of All-Girls Versus Co-Ed Groups, T. M. Chaplin, Jane Gillham, K. Reivich, A. G.L. Elkon, B. Samuels, D. R. Freres, B. Winder, M. E.P. Seligman

Psychology Faculty Works

Given the dramatic increase in depression that occurs during early adolescence in girls, interventions must address the needs of girls. The authors examined whether a depression prevention program, the Penn Resiliency Program, was more effective for girls in all-girls groups than in co-ed groups. Within co-ed groups, the authors also tested whether there were greater effects for boys than for girls. Participants were 20811-to 14-year-olds. Girls were randomly assigned to all-girls groups, co-ed groups, or control. Boys were assigned to co-ed groups or control. Students completed questionnaires on depressive symptoms, hopelessness, and explanatory style before and after the intervention. Girls …

The Effect Of Values, Conscientiousness, And Self-Efficacy On Ethical Decision-Making, Marcy Young

Student Work

This research explores the roles that values, conscientiousness, and self-efficacy play in ethical decision-making. Although previous research has shown that values affect ethical decision-making, few researchers have evaluated the effect that conscientiousness has on ethical decision-making. Research has evaluated the effect that self-efficacy has on ethical decision-making, but a relationship has not been found. The current study hypothesizes that individuals high in self-transcendence values will make more ethical decisions than individuals high in self-enhancement values. Also, individuals high in conscientiousness are expected to make more ethical decisions than individuals low in conscientiousness. Third, individuals high in self-efficacy are expected to …

Task-Dependent Posterior Cingulate Activation In Mild Cognitive Impairment, Michele L. Ries, Taylor W. Schmitz, Tisha N. Kawahara, Britta M. Torgerson, Mehul A. Trivedi, Sterling C. Johnson

Brain and Mind Institute Researchers' Publications

Neuroimaging research has demonstrated that the posterior cingulate cortex (PCC) is functionally compromised in individuals diagnosed with amnestic mild cognitive impairment (MCI), a major risk factor for the development of Alzheimer's disease (AD). In functional MRI studies with healthy participants, this same region is active during self-appraisal (requiring retrieval of semantic knowledge about the self) as well as episodic recognition of previously learned information. Administering both types of tasks to people with MCI may reveal important information on the role of the PCC in recollection. This study investigated fMRI activation in the PCC in individuals with MCI and matched controls …

Reduced Hippocampal Activation During Episodic Encoding In Middle-Aged Individuals At Genetic Risk Of Alzheimer's Disease: A Cross-Sectional Study, Mehul A. Trivedi, Taylor W. Schmitz, Michele L. Ries, Britta M. Torgerson, Mark A. Sager, Bruce P. Hermann, Sanjay Asthana, Sterling C. Johnson

Brain and Mind Institute Researchers' Publications

Background: The presence of the apolipoprotein E (APOE) ε4 allele is a major risk factor for the development of Alzheimer's disease (AD), and has been associated with metabolic brain changes several years before the onset of typical AD symptoms. Functional MRI (fMRI) is a brain imaging technique that has been used to demonstrate hippocampal activation during measurement of episodic encoding, but the effect of the ε4 allelle on hippocampal activation has not been firmly established. Methods: The present study examined the effects of APOE genotype on brain activation patterns in the media[ temporal lobe (MTL) during an episodic encoding task …

Historical Perspectives On Attitudes Concerning Death And Dying, David San Filippo Ph.D.

Faculty Publications

Beliefs and practices concerning death have changed throughout human history. In pre-modern times, death at a young age was common due to living conditions and medical practices. As medical science has advanced and helped humans live longer, attitudes and responses to death also have changed. In modern Western societies, death is often ignored or feared. Changes in lifestyles and improved medical science have depersonalized death and made it an encroachment on life instead of part of life. This has left many people ill equipped to deal with death when it touches their lives.
