This study focuses on the relationship of one cognitive ability test on long-term job performance as measured by personnel data. Archival data from over 3,000 employees at an international technology company were used to assess how aptitude test scores relate to both objective and subjective job performance measures. Supervisory performance ratings, level of promotion, and salary increase significantly contributed to variance in test scores; however, these results were inconsistent. Number of training courses did not have a significant relationship with test scores. Additionally, type of turnover did not moderate the relationship between aptitude test scores and job performance. These results indicate that although aptitude test score is related to long term job performance factors, other factors account for the majority of the variance. The implication is that aptitude should not be the sole consideration when predicting long term job success.

This investigation identifies deterrents to the educational, social, and cultural success of Latina adolescent females. Across the nation, and especially in states such as Texas and California, the Hispanic population is fast becoming the largest minority in society. Because the adolescent Hispanic population within the United States today will comprise much of America's future economic and social base, identifying and addressing educational, cultural, and social deterrents to their success becomes important not only for personal well-being, but for the well-being of future society as a whole. A second purpose was that of determining the efficacy of group-centered psychoeducational therapy in improving self-esteem and decreasing anxiety and depression symptoms in adolescent female Hispanic high school students. The experimental groups consisted of one group of seven female Hispanic adolescents who received computer and internet training and psychoeducational group counseling twice a week for five weeks. and a second group of five female Hispanic adolescents who received computer and internet training and psychoeducational group counseling twice a week for five weeks. The control group consisted of fourteen female Hispanic students who received no treatments. The Beck Depression Inventory was used to measure pre and post test levels of depression, the Beck Anxiety Inventory …

Coupons are one of the most popular and attractive tools of promotion. Redeeming coupons makes shoppers feel that they are doing something good for their family's budget, because coupons offer 'savings.' On the other hand, a coupon might have several negative effects on purchase behavior as well, which might 'devalue' the promoted product in the consumer's perception. But a review of the literature shows a lack of attention afforded to the above-mentioned aspects of coupon redemption. In addition, the consumer's coupon redemption behavior is moderated by several factors drawn from research in the fields of market pricing, economics and psychology, each of which have contributed to the current study in their own way. Finally, there does not exist any substantive research as to why coupon redemption rates have been on the decline, despite an increase in distribution of coupons. Therefore, this research not only fills existing gaps in the literature but also enriches it by synthesizing views from different academic disciplines. This dissertation concentrates on grocery products. Data is collected from about 2500 adults, primarily residing in the Dallas-Fort Worth area. The conceptual framework is based on the theory of reasoned action, which suggests that an individual's beliefs influence his/her …

There is almost a universal agreement among scholars in information retrieval (IR) research that knowledge representation needs improvement. As core component of an IR system, improvement of the knowledge representation system has so far involved manipulation of this component based on principles such as vector space, probabilistic approach, inference network, and language modeling, yet the required improvement is still far from fruition. One promising approach that is highly touted to offer a potential solution exists in the cognitive paradigm, where knowledge representation practice should involve, or start from, modeling the human conceptual system. This study based on two related cognitive theories: the theory-based approach to concept representation and the psychological theory of semantic relations, ventured to explore the connection between the human conceptual model and the knowledge representation model (represented by samples of concepts and relations from the unified medical language system, UMLS). Guided by these cognitive theories and based on related and appropriate data-analytic tools, such as nonmetric multidimensional scaling, hierarchical clustering, and content analysis, this study aimed to conduct an exploratory investigation to answer four related questions. Divided into two groups, a total of 89 research participants took part in two sets of cognitive tasks. The first group …

Into the Valley: Voices I Heard Along the Way contains a preface and a collection of five short stories. The preface discusses the use of voice as a technique to develop characters and create authenticity through elements such as sentence structure, diction, dialogue, and regional, cultural, and/or gender-specific affectations to make the words on the page become audible language in the mind of the reader. Each story is written with a unique voice that presents characters who struggle to come to terms with the truth and its various shades of reality.

This qualitative case study research examined how constructivist problem-based learning facilitated higher level thinking, increased interest in art, and affected attitude toward on-line courses in an undergraduate philosophical aesthetics and interpretation of art criticism course. The research conducted for this study suggests that constructivist problem-based learning does facilitate higher level thinking and increases student interest in art and in on-line classes. Active learning assignments, along with the constructivist collaborative class atmosphere, encouraged students to think more deeply about their personal values concerning art and to consider alternative views. Problem-based learning in this class acted as a scaffold to aid in understanding the material and then in applying the material to unique and real-life situations. Each subject came to the course with certain thinking skills and left with increased knowledge about art but also with increased critical thinking skills for critically examining and discussing art. Participants completed the course with more confidence in their critical thinking ability and in dealing with visual art images. Data was gathered from seven study participants in the form of highly-structured interviews, an early and final critical writing analysis, a major problem assignment and its reflection journal, a beginning survey, and two final surveys. The final …

With the increase in survival for children with cancer, part of the focus of current research is aimed towards evaluating how these children are adapting psychosocially. Neurocognitive deficits have been well established. However, there are multiple facets encompassing quality of life, including general mental health, lifestyles and health behaviors, and academic and cognitive functioning. The relationship between neurocognitive and psychosocial functioning has yet to be thoroughly evaluated. The purpose of this study was to investigate the relationship between neurocognitive and psychosocial functioning in survivors of brain tumors and acute lymphoblastic leukemia. Data was collected from existing archival database comprised of patients of the at Cook Children's Medical Center in Texas. The sample consisted of 177 patients between the ages of 3 and 12 who were at least two years post-diagnosis. Measures used included the NEPSY and the Behavioral Assessment for Children. Statistical analyses included a several one-way analysis of variances, an independent samples t-test, a univariate analysis of variance, a hierarchical multiple regression, and odds ratio analyses. Results indicated survivors treated with neurosurgery alone appear to be less at risk for developing behavior problems than other treatment modalities. Also, brain tumor survivors demonstrate more problematic behaviors than survivors of acute …

Diabetes has alarming prevalence rates not only in the U.S., but also worldwide. Ethnicity plays a large role with Hispanic-Americans having one of the highest prevalence rates. Diabetes is a complicated disease that requires significant lifestyle modifications. The health belief model (HBM) has been investigated as a theory to explain behavior change. However, little research has been done to determine its utility to Mexican-Americans. In the current study, participants were Mexican-American adults (N = 66) with type II diabetes who were recruited from family medicine clinics. Self-report questionnaires included the General Acculturation Index (GAI) and the Multidimensional Diabetes Questionnaire (MDQ). Participants had the option to complete them in either Spanish or English. Laboratory values were collected from medical charts. A MANCOVA indicated that two variables were significant, perceived severity (PS) and misguided support behaviors (MSB), p < .05. With respect to the HBM, PS was identified as a component of an individual's perception, acculturation was a modifying factor, and MSB was a component of the likelihood to change factors. These three affected glycemic control. Odds ratios determined that individuals with better glycemic control had less perceived severity and less misguided supportive behavior. Individuals with the least acculturation were more likely …

Transportation-related collisions are ubiquitous and often traumatic. Identifying post-collision psychological distress and the characteristics of the collision survivor that lead to distress are vital to the development of early and appropriate interventions. The goals of this study were: 1) to use a questionnaire as opposed to a typical diagnostic interview, 2) to confirm that psychological distress is present in currently hospitalized transportation-related collision survivors, 3) to confirm that different types of distress co-occur, 4) to determine if distress is more likely to occur in those who have had prior distress, and 5) to explore the relationship between symptoms of distress and perception of control by self, others, and God/Higher Power of past, present, and future collision-related events. Subjects were 100 English speaking adult inpatients, 16 years and older, who were less than 3 weeks post-injury, and receiving some rehabilitation. Participants completed a questionnaire which included the Center for Epidemiologic Studies Depression Scale (CES-D), Beck Anxiety Inventory (BAI), and Davidson Trauma Scale (DTS) as well as questions regarding demographics, details of the collision/injury, alcohol/drug use, pain, past and present stressors, social support, and perceptions of life change. Information about head injury and collision-concurrent alcohol and/or drug use was collected from the …

The purpose of this paper is to create a modern transcription/edition and an historical study of Munich Mus. Ms. 1511b thereby helping to define the social and pedagogical ramifications of lute repertoire from the mid-sixteenth-century. Because of the amateurish nature of the compositions, the conclusion of this study is that a member of the Herwarth family probably used the manuscript for learning purposes. Dance, grounds and other related forms found in the manuscript are discussed. Also included is an incipit concordance that can be used as a cross-reference for further research.

The luminescence properties of Van Der Waals' dimers and clusters of pyrene and diazapyrene have been investigated. Excimers, dimeric species which are associative in an excited electronic state and dissociative in their ground state, have long been established and play an important role in many areas of photochemistry. My work here focuses on the luminescence and absorption properties of ground state dimers/aggregates, which are less understood, and allows further characterization of the ground state and excited state association of these aromatic molecules.

Recent research has suggested that the effects of sport on well-being are mediated by psychological characteristics such as physical self-concept, instrumentality and positive body images; in addition, sport was found to be related to these psychological benefits for high school girls. However, physical self-concept played a central role by mediating the sport -body image and sport instrumentality relationships. Positive body image and instrumentality, in turn, predicted greater psychological well-being. The purpose of this investigation was to replicate earlier studies, and to examine these relationships with non-sport physical activity. Sport and physical activity were expected to contribute to higher physical self-concept, which in turn, would contribute positively to instrumentality and body image. Further, instrumentality and body image would be positively related to psychological well-being. Participants were 355 9th (n = 170) and 10th (n = 193) graders and they completed measures of involvement in sport/physical activities, physical self-concept, instrumentality, body satisfaction, self-esteem, satisfaction with life, depression, and demographics. Structural equation modeling was utilized to analyze the data. Overall, for both sport and physical activity, the models fit the data well (sport model: NNFI=.95, CFI=.96, SRMR=.08, RMSEA=.09, physical activity model: NNFI=.96, CFI=.97, SRMR=.08, RMSEA=.09). Specifically, sport participation was positively related to physical …

In order to assess the enhancement of seedling survival and growth during drought conditions, five-hundred bare-root seedlings each of Shumard oak (Quercus shumardii Buckl.) and green ash (Fraxinus pennsylvanica Marsh.) were planted each with four soil amendments at a Wildlife Management Area in Lewisville, Texas. The treatments were a mycorrhizal inoculant, mulch fabric, and two superabsorbent gels (TerraSorb® and DRiWATER®). Survival and growth measurements were assessed periodically for two years. Research was conducted on vegetation, soil, and site history for baseline data. Both superabsorbent gels gave significant results for Shumard oak survival, and one increased green ash diameter. For overall growth, significant results were found among DRiWATER®, mycorrhizae, and mulch treatments.

This study examined training evaluation practices in U.S. nonprofit sector organizations. It offered a framework for evaluating employee training in the nonprofit sector and suggested solutions to overcome the barriers to evaluation. A mail survey was sent to 879 individuals who were members of, or had expressed an interest in, the American Society for Training and Development. The membership list consisted of individuals who indicated association/nonprofit or interfaith as an area of interest. Data from the survey show that training in the nonprofit sector is evaluated primarily at Level 1 (reaction) and Level 2 (learning). It also shows decreasing use from Level 3 (application) through Level 5 (ROI). Reaction questionnaires are the primary method for collecting Level 1 data. Facilitator assessment and self-assessment were listed as the primary method for evaluating Level 2. A significant mean rank difference was found between Level 2 (learning) and the existence of an evaluation policy. Spearman rho correlation revealed a statistically significant relationship between Level 4 (results) and the reasons training programs are offered. The Kruskal-Wallis H test revealed a statistically significant mean rank difference between "academic preparation" of managers with Level 3 evaluation. The Mann-Whitney U test was used post hoc and revealed …

Research has shown that parents of children with disabilities, such as autism, experience significantly higher stress levels than parents of typically developing children. It has been suggested that parent education programs, in particular naturalistic communication training, will reduce parental stress. Most of the literature in this area has relied on parental reports and has only focused on decreasing stress and has not directly addressed increasing alternate feelings, such as happiness. In different but related areas of behavior analysis, an emphasis has been placed on the importance of happiness as a quality of life indicator and that the development of multileveled assessment is sorely needed. This study was designed to analyze one set of measures within a data-based intervention program for parents of toddlers with autism. The Family Connections Project (FCP) is a parent training project designed to enhance the quality of relationships for families who have toddlers with autism. Within this project parents are taught to identify and arrange opportunities to interact with their children in ways that will increase motivation and social responsivity. This study looked at the collateral effects of this training program and investigated if FCP affected the relationship between parents and their toddlers; of particular interest …

Research of social networks has revealed that certain components of network position can have an impact on organizational effectiveness, yet relatively little research has been conducted on network position and individual performance. This study sought to determine if a relationship exists between an employee's social network position and an individual's job performance. The participant organization was a network of individuals within an Information Technology (IT) department at a major defense company. A social network analysis (SNA) was conducted to determine the employee's network position, measured by centrality and constraint. Centrality refers to the extent to which an individual is connected to others. Constraint refers to how constrained or inhibited an individual is within the network. Performance was measured by annual appraisal ratings provided by the employee's supervisor. Hierarchical regression analysis was performed to determine relationships between the dependent variable (performance) and independent variables of centrality and constraint. Secondary variables also studied in relation to the model included education level, service years (tenure), job grade, and age. The overall model revealed 17% of variance explained. The primary predictors of network position, centrality and constraint, were not statistically significant predictors of performance ratings. Three variables, job grade, tenure and age, were found …

Despite the amount of scholarship on the Stamp Act Crisis, no study has used advertisements as a main source. This study attempts to show that a valuable, objective source has been overlooked, through the quantitative analysis of 5,810 advertisements before, during and after the Stamp Act Crisis from five port cities: Boston, Charleston, Philadelphia, New York, and Portsmouth. The findings reveal the colonists' strong connection to imported British luxury goods, and a lack of interest in American-made goods, especially before and after the boycott. Advertisements also demonstrate that the decision of many merchants to place the needs and expectations of their community before their own personal gain offered a rare economic opportunity for others. The colonists' devotion to imports tested the strength of the boycott, especially among Boston merchants, who continued to advertise imported goods a good deal more than any other city. This lack of dedication to the boycott on the part of the Boston merchants shows disunity among the colonies, at a time when many argue was the first instance of colonial nationalism. Capitalism challenged and undermined a commitment to communal sentiments such as nationalism. Moreover, if Americans did share a sense of nationhood during the Stamp Act …

The dynamic approach to fractional Brownian motion (FBM) establishes a link between non-Poisson renewal process with abrupt jumps resetting to zero the system's memory and correlated dynamic processes, whose individual trajectories keep a non-vanishing memory of their past time evolution. It is well known that the recrossing times of the origin by an ordinary 1D diffusion trajectory generates a distribution of time distances between two consecutive origin recrossing times with an inverse power law with index m=1.5. However, with theoretical and numerical arguments, it is proved that this is the special case of a more general condition, insofar as the recrossing times produced by the dynamic FBM generates process with m=2-H. Later, the model of ballistic deposition is studied, which is as a simple way to establish cooperation among the columns of a growing surface, to show that cooperation generates memory properties and, at same time, non-Poisson renewal events. Finally, the connection between trajectory and density memory is discussed, showing that the trajectory memory does not necessarily yields density memory, and density memory might be compatible with the existence of abrupt jumps resetting to zero the system's memory.

Scholars have evaluated the causes of clergy political preferences and behavior for decades. As with party ID in the study of mass behavior, personal ideological preferences have been the relevant clergy literature's dominant behavioral predictor. Yet to the extent that clergy operate in bounded and specialized institutions, it is possible that much of the clergy political puzzle can be more effectively solved by recognizing these elites as institutionally-situated actors, with their preferences and behaviors influenced by the institutional groups with which they interact. I argue that institutional reference groups help to determine clergy political preferences and behavior. Drawing on three theories derived from neo-institutionalism, I assess reference group influence on clergy in two mainline Protestant denominations-the Presbyterian Church (USA) and the Episcopal Church, USA. In addition to their wider and more traditional socializing influence, reference groups in close proximity to clergy induce them to behave strategically-in ways that are contrary to their sincerely held political preferences. These proximate reference groups comprise mainly parishioners, suggesting that clergy political behavior, which is often believed to affect laity political engagement, may be predicated on clergy anticipation of potentially unfavorable reactions from their followers. The results show a set of political elites (the clergy) …

The present study evaluates the psychometric properties of the TEAM Assessment Tool. The assessment was developed to evaluate work team effectiveness as a basis for providing developmental feedback for work teams. The proposed TEAM Assessment Tool includes 12 dimensions of work team effectiveness with 90 items total. The dimension names are (a) Communication, (b) Decision-Making, (c) Performance, (d) Customer Focus, (e) Team Meetings, (f) Continuous Improvement, (g) Handling Conflict, (h) Leadership, (i) Empowerment, (j) Trust, (k) Cohesiveness/Team Relationships, and (l) Recognition and Rewards. Data were collected from employees of a large aerospace organization headquartered in the United States who are participating in work teams (N= 554). Factor analysis guided development of six new scales of team effectiveness as follows: (1) Teamwork, (2) Decision-Making, (3) Leadership Support, (4) Trust and Respect, (5) Recognition and Rewards, and (6) Customer Focus. Reliability of scales was demonstrated using Cronbach's coefficient alpha. Construct validity was demonstrated through subject matter expert (SME) input, exploratory factor analysis, and scale reliability analysis. Criterion validity was demonstrated by significant correlations at the p<.01 level comparing two measures of team member opinion of team performance and level of performance as indicated by the six subscale scores and overall scale scores …

Sergei Mikhailovich Liapunov (1859-1924) was a distinguished Russian composer, pianist and teacher of the late 19th and early 20th century whose works are relatively unknown. His piano pieces were highly regarded and performed by pianists such as Konstantin Igumnov, Josef Hofmann, Josef Lhévinne, Ferruccio Busoni, and Vladimir Horowitz. However, they are rarely included in modern pianists' repertoire both in Russia and abroad, and are often viewed merely for their historic significance. Works of Liapunov are characterized by a life-affirming character and monumental beauty largely inspired by the images of nature as well as the sounds of his native Russian folk songs and dances. His music rarely conveys the urgency or profound melancholy which is often seen in the music composed during the same period by Rachmaninoff and Scriabin. Liapunov continued and enriched the great traditions of Russian music started by Glinka and The Mighty Five. He did not discover bold new ways of composing, and at the same time did not succumb to the temptation of following contemporary musical trends. The Twelve Transcendental Etudes, op. 11, dedicated to the memory of Franz Liszt, are masterpieces of immense value both from a technical and artistic standpoint. Just like Liszt's études, they …

Snow Spell is an interactive composition for erhu, flute, cello, piano, and Max/MSP interactive computer music system. This one-movement piece, Snow Spell, is intended to depict the beauty of a snow scene by presenting four different impressions of snow envisioned by the composer through music. The definition, history, and significance of interactive music are explored. Various modes of interactivity to control signal processing modules, and technical considerations for signal routing and level control in the interactive computer music system are also explored. Chinese music elements in Snow Spell including pentatonic scales, glissandi, and quotations from the Chinese folk tune River of Sorrow are investigated.

The purpose of the study was to investigate the impact of maternal stress as it relates to the mothers' perceived social behaviors of their preschool children in both immigrant Korean families in the US and Korean families in Korea. The subjects included 49 immigrant Korean mothers in the US and 52 Korean mothers in Seoul, Korea. This study is relevant to current research because of the dramatically increasing Korean immigrants in the US and needed information concerning unique cultural and psychosocial needs of Korean-Americans. All mothers completed the Demographic Survey, Parenting Stress Index (PSI), and Preschool and Kindergarten Behavior Scales-2 (PKBS-2). Statistical analyses of the data used for the study were multiple regressions, independent t-tests, and Pearson correlation coefficients. Data analysis revealed that (a) there were different demographic variables affecting maternal stress between immigrant Korean mothers in the US and Korean mothers in Korea; (b) there was no significant difference in maternal stress and mothers' perceptions of their preschool children's social skills in the areas of social cooperation, social interaction, and social independence between both groups; (c) there was a significant difference in preschool children's behavioral problems in the areas of externalizing and internalizing social-emotional behaviors between both groups; (d) …
