The Relationship Between Vicarious Traumatization and Job Retention Among Child Welfare Professionals
… satisfaction. Structural Equation Modeling (SEM) was used to assess the degree of fit between the observed data and several hypothesized theoretical models examining the relationship between vicarious trauma, coping strategies, professional efficacy, professional satisfaction, and retention. …

Evidence that aciniform silk and minor ampullate silk are major constituents of wrapping silk from the black widow
… that make up the swathing silk. Perfonning MS/MS analyses on solubilized wrapping silk fibroins digested with trypsin, we demonstrate that a novel fibroin named AcSp !-like is present within wrapping silk. Consistent with this finding, SEM analyses reveal that wrapping silk is a composite …

Problematic internet use: exploring the roles of attachment and social competency
… of PIU. Using Structural Equation Modeling (SEM) analyses, this study examined a mediation model that links adult attachment, social competency, and PIU. The proposed model was grounded in attachment theory and investigated both the direct and indirect effects of attachment on PIU as well as …

Temperament, emotion regulation, and distress tolerance as related correlates of psychological symptoms
… symptoms. This study used exploratory factor analyses and structural equation modeling to compose and test a model that explained how emotion regulation, distress tolerance, and coping skills interact to explain how certain temperament features translate into psychological symptoms. Because …

Associations between grandparental involvement and psychological outcomes in adolescents facing family adversity
… area was conducted. The results of bivariate and SEM analyses demonstrated that grandparental involvement was associated with a reduction in the presence of all negative psychological outcomes, which shows that grandparental involvement can play a compensatory role in adolescents' lives. The …

Klinische Bewertung von Kronen und Brücken aus Lithium-Disilikat-Glaskeramik
… a location, excluded by manufacturs guidelines. SEM analyses of the fractured connectors showed smaller dimensions than recommended. Relative failures occured mainly as minor and extended chippings of the veneering material (15). More than three-year clinical evaluation has demonstrated, that the …

Predictors of Eating Pathology in Adolescents: A Comparison of Ballet Dancers and Non-Dancers
… higher levels of pathological eating. However, SEM analyses indicated that the processes leading to pathological eating among dancers and non-dancers differ. Analyses of dancers’ experiences suggested that dancers did not perceive pressures to be thin from instructors or peers. Instead, dancers …

Potencial de Reaproveitamento do Concentrado da Osmose Inversa do Programa Água Doce – Bahia/Brasil Como Solução Osmótica no Processo de Osmose Direta
… to 15.92 mS/cm. Scanning Electron Microscopy (SEM) analyses revealed that the new membrane exhibited a uniform and unaltered morphology, with no evidence of fouling. In contrast, the used membrane showed precipitated salt deposits on its surface, which led to a reduction in water flux from 3.89 …

A study on chemical stabilization of Oil Sands Mature Fine Tailings
… are studied. Scanning electron microscopy (SEM) observations and X-ray diffraction (XRD) analyses are conducted to understand the microstructural changes in MFT after chemical stabilization. The results indicate that the inclusion of Portland cement or silicate grouts increases the solid …

Antibacterial activities of silver-nanoparticles-titania composite thin films fabricated by the molecular precursor method (MPM)
… Field Emission-Scanning Electron Microscopic (FE-SEM) analyses showed well dispensed Ag nanoparticles which appeared uniformly distributed across the films. Particles agglomeration and rough surface morphology were observed in films with high loads of Ag-NPs. Far-reaching absorption across the …

A longitudinal analysis of the relations between social, communication, and motor skills among students with autism
… model based on structural equational modeling (SEM). Descriptive and SEM analyses were conducted using R 3.0.1. Results show that (a) motor skills mediate the relation between communication and social skills in elementary school, but not in middle school, (b) communication, motor, and social …

The relationship among middle school students' motivation perceptions of science class, science identification and career goals
… students and Structural Equation Modeling (SEM) analysis was conducted to test the structure pattern among the MUSIC model components, science identification, and science-related career goals. Results indicate that with three of the MUSIC model components (i.e., usefulness, success, and …

An Integration of the Training Evaluation and Job Performance Modeling Literatures: Confirming BE KNOW DO with United States Army Special Forces Training Data
… time. Therefore, structural equation modeling (SEM) analyses were conducted to determine the relationship of similar constructs over time. Each construct from the initial training phase was found to predict its counterpart in the later phase. The degree of relationship varied for the constructs, …

Application of bacterial ligninase enzymes from rynchophorus ferrugineus’s gut consortium in agropulp biodelignification
… through UV-Vis spectrophotometer, FTIR and SEM analyses. The results showed that the gut microbes were solely able to degrade lignin with 30 to 60% in OPL and CG respectively, in which the highest delignification is obtained by the combination of all species. Furthermore, traces of small …

Examination of Complicated Grief, Posttraumatic Stress, and Other Psychological Reactions among Student Survivors of the April 16th Shootings at Virginia Tech
… Results of exploratory and confirmatory factor analyses supported CG as a unitary construct distinct from PTS and from anxiety/depression. Logistic regression results demonstrated that bereavement status was significantly predicted by CG but not PTS: Participants who scored 1 standard deviation …

The importance of personality, IQ and learning approaches : Predicting academic performance
… school subjects. The results from several SEM-analyses showed that personality, specifically Conscientiousness, has a positive influence on academic performance. In addition, there was a negative relation between Extraversion and academic performance and a positive relation between …
