The Rio Gavilan watershed, located in Mexico 's northern Sierra Madre Occidental , has significance in conservation history. Upon visiting the remote, largely un­developed watershed during two hunting trips in the 1930s, renowned conservationist Aldo Leopold thought it was the best picture of land health he had seen. His main indicators of healthy land were slow water runoff rates regulating erosion and historical predator-prey relationships. The visits confirmed Leopold's concept of land health, inspired many of his essays, and helped shape his land ethic. Leopold proposed the area as a control site to research healthy land throughout North America . The proposal never went forward and the area has since been more intensively logged and grazed. This dissertation research used extensive literature review, archives, oral histories, citizen surveys, and rapid assessment of forest, rangeland, riparian, and socioeconomic health to assess impacts of past cultures and update the area's land health status. Projects that could restore land health, such as linked eco-tourism, forest density reduction, and rotational grazing, were assessed for feasibility. Recent critiques of Leopold's land ethic were also reviewed. Results indicate most pre-1940s impacts were light, current land health status is moderate, and local interest exists in restoring land …

Among the goals of neuropsychological assessment are to detect the presence of brain damage, localize which areas of the brain may be dysfunctional, and describe subsequent functional impairments. The sensitivity of neuropsychological instruments in carrying out these functions has long been a question of debate. The purpose of the present study was to determine the utility of various performance level indictors and lateralizing indicators from the McCarron-Dial System Neuropsychological Assessment Battery (MDS) in ascertaining the presence or absence of brain damage as well as location of lesion. Models used in the present study appear to provide increased classification accuracy compared to other studies utilizing the MDS. The MDS was also shown to be comparable to other well-known neuropsychological batteries, including the Halstead-Reitan Neuropsychological Test Battery (HRB) and the Luria-Nebraska Neuropsychological Battery (LNNB) with regard to distinguishing between those with brain damage and normal controls, and also localizing brain lesion. The results of this study offer clinicians parsimonious models to evaluate for presence of lesion and its location so this information may be used to make accurate, thorough diagnoses and appropriate treatment and rehabilitation recommendations.

The United States government began paying pensions to disabled Union veterans before the Civil War ended in April 1865. By 1890 its pension programs included any Union veteran who had fought in the Civil War, regardless of his financial means, as well as surviving family members, including mothers, fathers, brothers, and sisters. Union veterans did not hesitate to "wave the bloody shirt" in their attempts to liberalize pension laws. Pension programs for Confederate veterans were much slower to develop. Lacking any higher organization, each southern state assumed the responsibility of caring for disabled and/or indigent Confederate veterans and widows. Texas began paying Confederate pensions in 1899, Georgia in 1888 and Virginia in 1889. Unlike Texas, Georgia and Virginia provided artificial limbs for their veterans long before they started paying pensions. At the time of his enlistment in the 1860s, the typical future pensioner was twenty-five years of age, and fewer than half were married heads of households. Very few could be considered wealthy and most were employed in agriculture. The pensioners of Georgia, Texas, and Virginia were remarkably similar, although there were some differences in nativity and marital status. They were all elderly and needy by the time they asked …

Failure to acknowledge their mental illness occurs in approximately half of all psychotic patients. Interest has been recently been refocused on insight (i.e., awareness of mental illness), and its associations with treatment compliance and better prognosis. Researchers have called into question the traditional factor structure of insight, instead viewing and defining it as a multidimensional and continuous construct. While factor analytic research has suggested that insight is an independent feature of psychotic disorders rather than a secondary manifestation of psychotic symptoms, several factor analytic studies have identified only one higher-order factor. Furthermore, a significant amount of the research literature has assessed insight or analyzed its relationships using only a single insight score. The current study evaluated the structural model of insight and assessed the associations between the different proposed dimensions of insight and psychotic symptoms. One hundred and six participants recruited from both inpatient and outpatient settings with a diagnosis of schizophrenia, schizoaffective disorder, psychotic disorder NOS, or bipolar disorder with psychotic features were rated on David's Schedule for Assessing Insight-Expanded Version (SAI-E), Birchwood's Insight Scale (IS), and the Brief Psychiatric Rating Scale (BPRS) or the Positive and Negative Syndrome Scale (PANSS). Structural equation modeling (SEM) was utilized to provide …

This dissertation discusses the potential of the snare drum as a solo concert instrument. Four pieces from a collection entitled The Noble Snare are used for demonstration ("Homily" by Milton Babbitt, "Composed Improvisation for Snare Drum" by John Cage, "Peeping Tom" by Dan Senn, and "The Noble Snare" by Stuart Saunders Smith). In the absence of many traditional musical devices (i.e. melody and harmony), alternative means of expression are used by the composer. Each piece is discussed with regard to its distinctive compositional approach and inherent performance issues. Information is also given pertaining to the background of the Noble Snare series. This includes: the inspiration for the project, editorial issues, and its influence on snare drum performance. Much of this research was completed through interviews by with author with Sylvia Smith, publisher of The Noble Snare and owner of Smith Publications.

This study investigated the effect of cognitive factors on competency to stand trial. Previous researchers have investigated how psychological variables --such as psychosis and intelligence--contribute to incompetency. Although several researchers have established that intelligence contributes to incompetency, very few have investigated the role of specific cognitive abilities within the realm of intelligence. This study investigated the performance of 55 defendants referred for competency restoration on neuropsychological measures. Specifically, competent defendants and incompetent defendants were compared on several measures assessing functioning in seven cognitive domains. Competent defendants performed significantly better than incompetent defendants on measures of verbal comprehension, social judgment, verbal memory, and executive functioning. Competent and incompetent defendants did not differ on attention, visual spatial skills, or nonverbal memory.

The purpose of this study was to investigate predicting student success on one example of a "high stakes" test, the Texas Assessment of Academic Skills Exit Level Exam. Prediction algorithms for the mathematics, reading, and writing portions of the test were formulated using SPSS® statistical software. Student data available on all 440 students were input to logistic regression to build the algorithms. Approximately 80% of the students' results were predicted correctly by each algorithm. The data that were most predictive were the course related to the subject area of the test the student was taking, and the semester exam grade and semester average in the course related to the test. The standards of success or passing were making a 70% or higher on the mathematics, 88% or higher on the reading, and 76% or higher on the writing portion of the exam. The higher passing standards maintained a pass/fail dichotomy and simulate the standard on the new Texas Assessment of Knowledge and Skills Exit Level Exam. The use of the algorithms can assist school staff in identifying individual students, not just groups of students, who could benefit from some type of academic intervention.

The purposes of this study were to examine the prevalence of current substance use and early risk indicators for substance abuse and dependence, and to investigate the relationships among religiousness, current substance use, and early risk indicators among nursing students at seven Seventh-day Adventist colleges. Data for this descriptive study were collected through Efinger's Alcohol Risk Survey (EARS) (Efinger, 1984), the CAGE Questionnaire ( Ewing , 1984), and the Intrinsic/Extrinsic-Revised Scale (Gorsuch & McPherson, 1989). Participants were 241 nursing students enrolled in their first year of nursing courses at seven colleges and universities located across the United States . Findings indicated that 42% of students scored higher than the EARS mean; 24% reported current substance use; and 15% scored in the probable abuse/dependence category of CAGE. Students who reported current substance use and those scoring in the probable substance abuse/dependence category were significantly more likely to score above the EARS median. Intrinsic religiousness demonstrated a significant inverse relationship with current substance use. Significantly lower rates of current substance use were associated with higher rates of attendance at religious services. Respondents who indicated that their religion prohibited alcohol consumption reported significantly lower rates of current substance use than those who answered …

This project investigated the metacognitive strategies used to appraise obsessive thoughts employed by individuals with different anxiety symptoms. Two hundred eighty-seven undergraduate students completed two repertory grids and three anxiety scales. The repertory grids respectively examined the appraisal process of intrusive thoughts both from the perspective of the rater and the rater's imagined average person. Variables quantified from the rep grid related to the construal process of raters' own intrusions, failed to demonstrate robust differences between OCD, non-OCD anxious, and non-anxious individuals. However, it appears that anxious individuals, not just those with OCD, use metacognitive strategies to suppress rigid constructions under perceived social evaluation. Future studies may wish to use related grid variables to explore the relation between obsessions and social anxiety.

Capitalism's success, according to Karl Marx, is based on continued development of new markets and products. As globalization shrinks the world marketplace, corporations are forced to seek both new customers and products to sell. Commodification is the process of transforming objects, ideas and even people into merchandise. The recent growth of the World Wide Web has caught the attention of the corporate world, and they are attempting to convert a free-share-based medium into a profit-based outlet. To be successful, they must change Web users' perception about the nature of the Web itself. This study asks the question: Is there mythic evidence of commodification on the World Wide Web? It examines how the World Wide Web is presented to readers of three national publications-Wired, Newsweek, and Business Week-from 1993 to 2000. It uses Barthes' two-tiered model of myths to examine the descriptors used to modify and describe the World Wide Web. The descriptors were clustered into 11 general categories, including connectivity, social, being, scene, consumption, revolution, tool, value, biology, arena, and other. Wired articles did not demonstrate a trend in categorical change from 1993 to 2000; the category of choice shifted back and forth between Revolution, Connectivity, Scene, and Being. Newsweek …

Although federal circuit and district court judges are placed within a federal hierarchy, and receive legal and judicial training that emphasizes the importance of the judicial framework and its structure, such judges are also subjected to other pressures such as the types of litigants within the courtrooms as well as their local political environment. Furthermore, such judges are apt to form their own views about politics and legal policy and are often appointed by presidents who approve of their ideological leanings. Thus, federal courts are caught between competing goals such as their willingness to maximize their preferred legal policy, and their place within the judicial hierarchy. This dissertation applies hierarchy and impact theory to assess the importance of the judicial framework and its socialization, by analyzing both the judicial opinions and votes of federal circuit and district court judges in obscenity cases during a four-decade period (1957-1998). The research presented here finds the influence of higher court precedent to correspond in part with the conception of a judicial hierarchy. An analysis of citations of Supreme Court precedent (Roth v. United States (1957) and Miller v. California (1973)) in lower court majority opinions suggests low levels of compliance: lower courts at …

When a client has cognitive impairment resulting from cerebral dysfunction (CD) that goes undiagnosed and, therefore, untreated, psychotherapy and rehabilitation outcome is likely to be impacted negatively. Due primarily to managed care, screening for CD has reduced substantially. Master's level counselors need a cost-efficient way to detect possible CD and, thus, justify referral for neuropsychological evaluation. This study examined the Wechsler Abbreviated Scale of Intelligence™ (WASI™) instrument's ability to screen for possible CD by examining the relationship between a) WASI Performance IQ (PIQ) and Verbal IQ (VIQ) scores and neuropsychological test scores, and b) the VIQ-PIQ discrepancy and the severity of disability. In this retrospective study, test scores were extrapolated from neuropsychological assessments conducted between 2001 and 2004 on 73 CD-diagnosed adults at a CARF accredited rehabilitation facility. Disability severity ratings of mild, moderate, and severe were assigned based on clinical judgment and interrater agreement. The assessment battery included the WASI and several neuropsychological tests: Halstead-Reitan TPT, TMT-A and B, and FOT; WMS-III VR-I and 2, LM-1 and 2, and MC; McCarron-Dial HVDT; SDMT; and SCT. Based upon a multitrait-multimethod matrix, mild to moderate convergent and discriminant validity was found with the WASI VIQ and PIQ traits among neuropsychological verbal …

The present study examined various psychosocial variables that may influence success in a stop smoking program (QuitSmart) used by the North Texas Veterans Health Care Service (NTVHCS). The QuitSmart program utilizes the Stages of Change Model, with its focus on the last three stages (preparation, action, and maintenance). It was proposed that factors including shame-proneness, guilt, anger/hostility, depression, self-efficacy - both global and smoking situational, neuroticism, and level of nicotine dependence might individually or in combination predict attrition from the NTVHCS smoking cessation program. Results indicate that shame-proneness, guilt, anger/hostility, and depression did not individually predict attrition. Persons with high levels of smoking situational self-efficacy tend to utilize self-change strategies leading to greater success in smoking cessation. Participants with a psychological diagnosis, when combined with neuroticism and shame-proneness, appear to have more difficulty with cessation than those with only a medical diagnosis. Clinical implications and suggestions for change to the NTVHCS smoking cessation program are discussed.

Museums and libraries are considered large repositories of human knowledge and human culture. They have similar missions and goals in distributing accumulated knowledge to society. Current digitization projects allow both, museums and libraries to reach a broader audience, share their resources with a variety of users. While studies of information seeking behavior, retrieval systems and metadata in library science have a long history; such research studies in museum environments are at their early experimental stage. There are few studies concerning information seeking behavior and needs of virtual museum visitors, especially with the use of images in the museums' collections available on the Web. The current study identifies preferences of a variety of user groups about the information specifics on current exhibits, museum collections metadata information, and the use of multimedia. The study of information seeking behavior of users groups of museum digital collections or cultural collections allows examination and analysis of users' information needs, and the organization of cultural information, including descriptive metadata and the quantity of information that may be required. In addition, the study delineates information needs that different categories of users may have in common: teachers in high schools, students in colleges and universities, museum professionals, art …

The present study compared the career development concerns and other vocationally relevant variables of employees of organizations who have and have not engaged in downsizing within a one year timeframe. The sample consisted of 162 participants, 72 layoff survivors (those who remained in an organization after its downsizing) and 92 non-survivors (employees in organizations who have not downsized within 12 months). Significant results were found that differentiated the career related experiences of participants in the survivors group, survivors from non-survivors, and participants in general regardless of survivorship status. In general, results indicated that non-survivors reported greater job satisfaction and job security than layoff survivors, that being married with children may increase job satisfaction, and social support may buffer the grief reactions that survivors have to the loss of their co-worker friends. Furthermore, Super's age-associated stages within the Life-Span, Life-Space Theory were moderately upheld in the sample, especially for the Exploration stage. However, younger workers demonstrated more Maintenance concerns that would be predicted by the theory. A discussion of the relevant literature is included as well as possible explanations of the results, small sample size, and implications for future research.

Social and cognitive skill acquisition were evaluated in 33 (male=24, female=11) outpatients with schizophrenia or schizoaffective disorder. A social skills training treatment group (n=19) was compared to a wait-list control (n=14). Participants' mean age was 41 years, mean number of hospitalizations 10.4, and mean number of years with diagnosis 15.8. Assessment measures included WAIS-III Picture Arrangement subtest, Social Cue Recognition Test, COGLAB, WMS-III Word List subtest, and SADS-C. Results did not support the main hypotheses of improved social and cognitive skills in the treatment group. Participants with better memory and attention at pre-testing also did not show an advantage in social skills improvement. Contrary to hypotheses, the control group improved the most on some social and cognitive measures. Several supplemental hypotheses yielded the following results: lack of volunteer participation from paranoid schizophrenia individuals; evidence that schizoaffective disorder participants may be less cognitively impaired and better able to benefit from social skills training; and younger, less chronic participants with better attentional capacities may benefit most from social skills training. Findings are discussed in light of the possibility that improving social skills might not improve social and cognitive functioning, at least with the dosage of social skills training provided in this study. …

The present study contributes to the widening body of spirituality research by conceptualizing it as a state-trait construct. A new measure of spirituality, the State-Trait Spirituality Inventory (STSI), was created and validated according to psychometric methods of test construction. In its current form, the STSI contains seven state spirituality items and six trait spirituality items. A thorough review of the literature identified common themes in spirituality definitions and assisted in developing definitions of trait and state spirituality. Internal consistency for the trait scale was .88 and for the state scale, .68. Good test-retest reliability was found with coefficients of .84 for trait spirituality and .81 for state spirituality. Results from a preliminary undergraduate sample as well as from the validation sample yielded a two-factor solution. In general, items determined by expert panels as trait items loaded on one factor and items deemed to be state items loaded on the second factor. Multitrait multimethod analysis yielded mixed findings for convergent, divergent, and concurrent validity for the spirituality and religiosity traits. Methods consisted of paper-and-pencil cognitive and behavioral measures. Cognitive measures were more likely to support convergent/divergent validity than were behavioral measures. A major emphasis in the study was to determine whether …

The current study investigated the relationship between clients' object relations functioning and the working alliance. The Social Cognition and Object Relations Scale (SCORS; Westen, 1991), an object relations scoring system for the TAT, was used to assess object relations functioning. Forty-eight therapy clients at a university-based training clinic were administered the TAT, Adult Attachment Scale (AAS), Symptom Checklist 90-Revised (SCL-90-R; Derogatis, 1977), and the short form of the Marlowe-Crowne Social Desirability Scale (MCSD; Crowne & Marlowe, 1960). Following the initial assessment of client characteristics shortly after intake, clients and their therapists rated the working alliance 3 sessions later. Results indicated that the SCORS was significantly correlated with client and therapist ratings of the working alliance. The current study also assessed the predictive validity of the SCORS by examining how its various scales are related to aspects of the working alliance and the other measures used in this study. The findings suggest that the relationship between object relations functioning, the working alliance, symptom severity, and attachment disturbance depends on the aspect of object relations that is being assessed.

Wayfinding is the process of using one or more tools to move from one location to another in order to accomplish a task or to achieve a goal. This qualitative study explores the process of wayfinding as it applies to locating information in a public library. A group of volunteers were asked to find a selection of items in three types of libraries-traditional, contemporary, and modern. The retrieval process was timed and the reactions of the volunteers were recorded, documented, and analyzed. The impact of various wayfinding tools-architecture, layout, color, signage, computer support, collection organization-on the retrieval process was also identified. The study revealed that many of the wayfinding tools currently available in libraries do not facilitate item retrieval. Inconsistencies, ambiguities, obstructions, disparities, and operational deficiencies all contributed to end-user frustration and retrieval failure. The study suggests that failing to address these issues may prompt library patrons-end users who are increasingly interested in finding information with minimal expenditures of time and effort-may turn to other information-retrieval strategies and abandon a system that they find confusing and frustrating.

Cowpea, Vigna unguiculata (L.) Walp is an excellent source of protein, vitamins and minerals and a major food crop many parts of Africa. Optimal production levels are hampered by insect pests and diseases. Biotechnological techniques such as tissue culture and genetic engineering can aid in the development of varieties with resistance to insect pests and diseases. The objective of this study was to investigate conditions necessary for the development of a reproducible tissue culture system that can be applied to regenerate transformed cells from culture. The in vitro manipulation of cowpea using Murashige and Skoog (MS) medium, auxins and cytokinins resulted in the formation of callus and rhizogenesis. Calli that were formed were separated into six classes based on color and texture. Yellowish friable callus, yellowish compact, soft yellowish callus and green and white were composed of largely vacuolated cells and were non-regenerative. Friable green callus was the most prevalent callus type and could form of roots in some hormone combinations. Green spots were formed on hard compact green callus. The green spots became nodular, forming root primordia and ultimately giving rise to roots. None of the six calli types gave rise to the formation of shoots. Embryogenic callus was …

The thrust of this paper was two-fold, 1) to confirm a 2-factor model of narcissism in women, and 2) to examine the relationship between narcissistic traits in mothers and several variables associated with parenting efficacy. Participants included 193 mother-child dyads. A 2-factor model of narcissism was confirmed in the present sample of mothers, suggesting that narcissistic traits in women may be manifested in distinct Overt and Covert forms. Contrary to expectations, Covert Narcissistic traits in mothers did not significantly correlate with observed parenting behaviors on the PCIA, including Positive Personal Comments (PPC) towards children, Negative Personal Comments (NPC), and Parental Nurturance. However, children's self-reported maternal rejection on the C-PARQ correlated positively with Covert Narcissistic traits in mothers, as did mother's self-reported dysfunctional parenting attitudes on the AAPI-2. Narcissistic traits in mothers correlated most strongly with risk of child physical abuse on the CAPI (r = .70). Results are also presented for the Overt Narcissism factor, which proved to be less stable as a factor. Overall, results emphasize the need for a more comprehensive understanding of narcissism for women, given its potential Implications for children's healthy development and parenting interventions.

This study examined the relationship between physical health, social support, and depression in a married, middle-aged/older adult sample in which at least one partner has heart disease. The data was obtained from a national longitudinal study the Health and Retirement Survey (HRS) and is composed of selected respondents and their spouses. The HRS Wave 1 data that was used for these analyses was collected in 1992 and 1993. This study tested a stress buffer model predicting the relationship between physical health, social support, and depression. For study inclusion, participants must have been diagnosed with cardiovascular disease and received treatment in the last year. A heart disease construct was developed by calculating the level of disease by the number of conditions and medical treatments received within the last year. A second health category for other chronic health conditions included diabetes, arthritis, cancer, and chronic pain. These constructs were combined into a total disease construct, which provided a broad measure of health problems typical of an older adult population. Social support was determined by respondents' satisfaction with friends, neighbors, family, their marriage, and enjoyable time spent with their spouse. Social support was subdivided into two constructs separating spousal support from social support …

This study investigated whether a relationship exists between learning style and the self-reported technology-related needs, beliefs, stages of adoption, software expertise, and technology competencies of teachers in a large suburban school district. The Gregorc Style Delineator was used to identify dominant learning style, and the Snapshot Survey was used to measure technology-related needs, beliefs, stages of adoption, and software expertise. Technology competencies were measured using the Technology in Education Competency Survey. Data collected from 499 participants was included in data analysis. The study was conducted at each of the 12 elementary schools of a large suburban district in the Dallas-Fort Worth Metroplex. The findings suggest that there is a significant relationship between learning style and the technology-related needs, stages of adoption, software expertise, and competencies of teachers. The relationship between learning style and technology-related needs was significant at the p < .01 level. The relationships between learning style and technology-related stages of adoption, software expertise, and technology competencies were significant at the p < .05 level. Members of the abstract sequential [AS] learning style group reported having significantly fewer needs and significantly higher stages of adoption, software expertise, and competency than members of one or more of the other learning …

The purpose of the present study was to study the relationship of MCMI-III clinical scales with MMPI-2 clusters in a chronic pain population. Data was obtained through assessment data (N = 242) from the Dallas Spinal Rehabilitation Center (DSRC), that included MMPI-2 and MCMI-III, as well as pre-and post-assessment information (n = 21) and follow-up questionnaires (n = 19). Subjects' age ranged from 18 to 64. Each patient had a primary diagnosis related to a back and/or a cervical injury, a chronic pain diagnosis, and often medical prescription dependency and/or addition. Each has experienced back pain in the lumbar region (L1 to L5) or cervical region (C1 to C7) for an average of 32 months. Patients with thoracic (mid-spine) and carpal tunnel pain were excluded from this study. A multivariate cluster analysis procedure was performed that yielded 3 homogeneous female MMPI-2 clusters and 4 MMPI-2 homogeneous male clusters. Seven multiple regression analyses were performed to determine which MCMI-III clinical scales predicted cluster membership in the MMPI-2 clusters. Results indicated that MCMI-III clinical scales "7" Compulsive, "X" Validity and "C" Borderline were predictors for membership in the male MMPI-2 clusters. Membership in the female MMPI-2 clusters were predicted by MCMI-III clinical …
