Behavioral Effects Of Tyrosine During Sustained Wakefulness, D. L. Wiegmann, D. F. Neri, R. R. Stanny, S. A. Shappell, A. H. Mccardie, D. L. Mckay

Publications

The fatigue and cognitive performance deficits associated with sleep loss and stress, like that experienced during sustained flight operations and nighttime flying, have motivated the search for effective nonpharmacological countermeasures. The behavioral effects of the potential countermeasure tyrosine, an amino-acid precursor to dopamine and norepinephrine, were examined during an episode of continuous nighttime work involving one night's sleep loss. Volunteers performed nine iterations of a battery of cognitive and subjective tasks for approximately 13 h, beginning at 1930 and ending at 0820 the following morning. Subjects remained awake throughout the day on which the experiment began and were awake for …

The Effects Of Perceived Work Schedule Flexibility, Number Of Hours Worked, And Type Of Work Schedule On Work-Family Conflict, Tenora Dianne Grigsby

Dissertations and Theses

The interaction effects of perceived work schedule flexibility (PWSF) and the number of hours worked on work-family conflict, and the interaction effects of PWSF and the type of work schedule on work-family conflict were investigated for employees of a regional bank headquartered in the Pacific Northwest. A 50% response rate was obtained from a survey questionnaire administered to 2,000 randomly selected employees.

Hierarchial multiple regression analyses conducted on 526 subjects revealed no significant interaction effects for PWSF and type of work schedule. The interaction effect for PWSF and number of hours worked was not tested due to a significant correlation …

The Perceptual Weighting Of Speech-Related Acoustic Cues For 3 & 1/2-Year-Old Children Differs From That Of Adults: Results Using Natural And Synthetic Stimuli, Carol J. Manning

Student Work

Previous studies have found that children’s judgments of syllable-initial /s/ and / ∫ / are more related to the vocalic F2 transition and less related to the fricative-noise spectrum than are adults’ judgments [Nittrouer & Studdert- Kennedy, JSHR, 30 (1987); Nittrouer, J. Phon., 20 1992]. These results have been taken as evidence that young children organize linguistic input in units more closely approximating syllable size than phoneme size. Furthermore, such results have led to a model of speech development proposing that children’s weighting of the acoustic cues for phonemic categories changes as they gain linguistic experience, with a general shift …

The Effect Of The Cooper Wellness Program In Promoting Long- Term Lifestyle Behavior Changes, Ernesto P. S. Medina Jr.

Loma Linda University Electronic Theses, Dissertations & Projects

Most research on health behavior change programs examines their effectiveness in producing initial behavior changes, but fails to evaluate long-term maintenance of those changes. This study examined the effectiveness of the Cooper Wellness Program (CWP) in Dallas, Texas, in promoting maintenance of lifestyle behavior changes for one year or longer in the areas of diet, exercise, and stress management.

The CWP offers an intensive live-in lifestyle behavior modification program in four-, seven-, or 13-day formats. Data were collected from 223 individuals who attended the CWP between January, 1989, to February, 1992. The study addressed the following areas: 1) long-term maintenance …

Determinants Of Elite Athletes' Commitment To Sport: Examination Of The Sport Commitment Model In The Professional Sport Domain, Tammy Kay Hall

Dissertations and Theses

This study examined the applicability of the Sport Commitment Model for a group of elite, professional athletes. The model proposes that an athlete's commitment will increase as sport enjoyment, personal investments, social constraints, and involvement opportunities increase and will decrease with an increase in involvement opportunities. The influence of identification as an athlete, a determinant of commitment not included in the original model, was also examined. One hundred and eighty three professional football players from the Canadian Football League (CFL) (n = 121) and National Football League (NFL) (n = 69) participated in the study. Each subject completed …

Validation Of A Portuguese Form Of Templer's Death Anxiety Scale, James M. Donovan

Law Faculty Scholarly Articles

To translate Templer's Death Anxiety Scale into the Brazilian Portuguese Escala de Ansiedade de Morte, linguistic validity was first established by back-translation and calculating bilingual split-half reliability coefficients. Even-numbered items achieved a minimally adequate .59, while the odd-numbered items attained a satisfactory .91. The internal consistency of the Escala (.77) matches that found for the original scale. The construct validity was tested by replicating the interactions of the English form with (1) the State-Trait Anxiety Inventory, (2) the Purpose-in-Life Test, and (3) Levenson's measure of locus of control. The Escala performed as expected, save for some difficulty with the locus …

Correlates Of Job Satisfaction Among Private Sector Employees In Saudi Arabia, Abdullah Al-Helelah

Masters Theses

The primary objectives of the present study were to explore the level of job satisfaction and commitment among private sector employees in Saudi Arabia, and to examine the relationship between job satisfaction and employees' commitment.

Seven alternative hypotheses were tested against seven null hypotheses. Chi-square (x^2) was the test statistic for all seven hypotheses. The critical value of chi-square was determined by the degrees of freedom (df) and an alpha level of.05. Three hypotheses were confirmed that related job satisfaction to employees' commitment, satisfaction with length of working hours, and satisfaction with opportunities for interaction with co-workers on the job. …

An Examination Of The Relationship Between Work Involvement And Family Involvement And Work-Family Conflict In Dual-Career Families, Elizabeth Jean Allen

Dissertations and Theses

The present study examined the relationship between work involvement and family involvement and work-family conflict in dual-career families. Four hundred thirty-six couples (436 females; 436 males; N = 872) in dual-career relationships were recruited from a bank organization in the Northwest United States. The survey questionnaire contained three sections to measure work and family involvement, work-family conflict, and sociodemographic information. Data analyses were conducted using multiple regression analysis and a 1 X 4 ANOVA to examine the proposed relationships among the study variables. Results demonstrated the following: across study participants, work involvement accounted for a significant amount of variance in …

Intersection Decisions And Reaction Time, Orhan Earle Beckman

Psychology Theses & Dissertations

Reaction time (RT) as a dependent variable can be used to assess human performance and identify variables influencing performance. Donders (reprinted in English as Donders, 1969) defined three types of reaction time (RT). Simple RT is defined as RT in a situation involving one stimulus and one response. The selective reaction time (SRT) is defined by a situation involving two or more stimuli with only one possible response. Choice reaction time (CRT) is defined by a situation with more than one stimulus category and an equal number of possible responses.

The Hick-Hyman law defines CRT as a logarithmic function of …

Choice Reaction Time And Conjunctions Of Form Size Color And Orientation, Cristina Bubb-Lewis

Psychology Theses & Dissertations

Reaction time (RT) is frequently used as a dependent measure in studies that examine the organization of perceptual and cognitive processes. Hick's law states that RT in a choice-reaction-time (CRT) task is a linear function of the amount of information transmitted per stimulus-response event. RT has been used to try to determine whether serial or parallel processing is being employed in CRT tasks (Sternberg, 1966). There is research evidence suggesting a serial, exhaustive search process (Sternberg, 1969a; Wingfield, 1973), as well as findings which suggest parallel processing (Neisser, 1963; Neisser, Novick, and Lazar, 1963) in CRT tasks. All the experiments …

A Test Of Bass's Model Of Transformational Leadership Among Managers In The Dominican Republic, Nancy Urbaez Echavarria

Psychology Theses & Dissertations

This study tested the generalizability of Bass's theory of transformational leadership to employees of a company in the Dominican Republic. A Spanish translation of Bass's Multifactor Leadership Questionnaire (MLQ) was used to assess the leadership styles. The factor structure for Dominican workers was not identical to the structure observed in United States samples. Nevertheless, the pattern of results followed rather closely the pattern observed in United States samples. Consistent with research conducted in the U.S., subordinates who had transformational leaders reported more satisfaction and effectiveness and greater effort and organizational innovativeness than subordinates who had transactional or laissez faire leaders. …

Materialism And The Self, Kathleen Shirley Micken

Theses and Dissertations in Business Administration

Materialism has been called the most significant macro development in modern consumer behavior. Despite its importance, research about the construct is rather new. Two scales have been developed to measure materialism, one proposed by Belk, the other by Richins and Dawson.

The purpose of this dissertation is threefold. First, it extends the materialism research program by investigating the relationship between materialism and one's self concept. Hypotheses which drive the research posit that people who are more materialistic have lower self-esteem, are less likely to be self-actualized, are extrinsically rather than intrinsically motivated, and are likely to be high self-monitors. The …

A Study Of Gender And Personality Factors In Work-Family Conflict Models, Steven Donald Ward

Dissertations and Theses

There were three underlying purposes to this study: 1) To test the main effect of gender on work -> family and family -> work conflict; 2) To re-examine the predictors of inter-role conflict used by Frone, Russell, and Cooper (1992) (i.e., job involvement, job stress, family involvement, and family stress); and 3) To investigate the importance of using personality characteristics as predictors of how individuals deal with inter-role conflict. A questionnaire was assembled, consisting of: a work -> family conflict spillover scale, a family -> work conflict spillover scale, a job involvement scale, a family involvement scale, a job stressors …

Spanish Translation And Validation Of The Daily Stress Inventory, And A Comparison Of The Level Of Stress Experienced By Three Culturally Distinct Hispanic Groups, Senez Rodriguez-Charbonier

Dissertations

High levels of stress in the general population have been found to correlate both with psychological and physical illness. The fast growing Hispanic population in the U.S. is exposed to increased levels of stress associated with a number of situations (e.g., language barriers, and socioeconomic status). There are, however, no validated stress measures applicable to the Hispanic community as a whole.

The purpose of this study was twofold: First, to translate into Spanish the Daily Stress Inventory (DSI) (Brantley & Jones, 1989) and to validate the translation by conducting a correlation study between the the Spanish and the English versions. …

A Model To Predict Recycling Behaviors: Reusing Ajzen's Model One More Time, Kathleen L. Kiwala

Dissertations and Theses

The prediction of self-reported recycling behaviors was examined using variations and expansions of Ajzen's theory of planned behavior. Three hundred and forty-eight residents from the Multnomah, Clackamas and Washington counties in Oregon completed a questionnaire that assessed attitude, subjective norms, perceived behavioral control, intentions, self-reports of recycling behavior, moral obligation and past behavior. Recycling behaviors and intentions were grouped into three categories of difficulty by a factor analysis. Structural equation analysis did not support Ajzen's model. It was found that although attitudes was correlated with the antecedent variables, it did not directly influence intentions or behaviors. Perceived behavioral control had …

Perceived Control: Precursors To Achievement In Oglala Lakota Children, Stephen Blaine Cook

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The discrepancy between American Indian and Caucasian children in academic achievement is well documented. Theorists suggest a connection between perceived locus of control and the level of educational performance. This study first sought to determine if the factor structure of a measure of the perception of lo cu s of control (Multidimensional Measure of Children's Perceptions of Control) was similar for Caucasian and American Indian (Oglala Lakota) children. Second, the study sought to determine if there were differences between the groups on the MMCPC subtest scores. Finally, the study sought to determine the relationship between locus of control and academic …

The Relationship Between Perceived Parenting Styles And Adolescent Locus Of Control And Self-Concept, Lisa Ann Mcclun

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Relationships between adolescents' perceptions of their parents' responsiveness and demandingness, adolescents' locus of control orientation, and adolescents' self-concept ratings were investigated. Subjects included 198 students from a middle school in northern Utah. Subjects were given the Nowicki-Strickland Internal-External Control Scale for Children, the Harter Self-Perception Profile for Adolescents, and the Perceived Parenting Style Survey.

Results indicated that subjects who perceived their parents as being authoritative had significantly (p < .001) more internal locus of control scores than subjects who reported either the permissive or authoritarian styles. Also, self-concept scores were significantly higher (p < .001) for the authoritative group than the authoritarian group on the Self-Perception Profile for Adolescents subscales of Scholastic Competence, Social Acceptance, Physical Appearance, Behavioral Conduct, Close Friendship, and Global Self Worth. The permissive group reported significantly lower scores (p < .05) on the subscales of Scholastic Competence and Behavioral Conduct. There was also a significant negative correlation (p < .001) between locus of control scores and the subscale scores on the Self-Perception Profile for Adolescents.

Although there were some limitations in the study methodology, the significant differences found between the groups indicated that the authoritative parenting style positively correlates with higher self-concept and …

Intraventricular Hemorrhage Sequelae In Low Birthweight Infants: A Meta-Analysis, Shannon G. Thompson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Technological advances in neonatal care have dramatically improved the survival and disability rates among low birthweight infants (LBW). One common factor associated with later problems among these babies is intraventricular hemorrhage (IVH). A meta-analysis was conducted among LBW infants with and without IVH to determine developmental outcome. More than 450 studies were located. Only 125 studies met inclusion criteria.

Mean effect sizes were computed by comparing the LBW group to either a fullterm control group or to test norms. When compared to fullterm children, LBW children scored worse in all areas except gross motor skills.

Cognitive assessment was done commonly …

Perception Of Leadership Style And Job Satisfaction, Carlos Holgado

Theses and Dissertations

The relationship between the perception of leadership behaviors, self-perception (managers and supervisors) vs. perception of others (staff members), and the level of job satisfaction of those staff members will be analyzed.

The main focus of the present study is to determine what the relationship is among the four basic leadership behaviors - Telling, Selling, Participating, and Delegating- based on the Situational Leadership theory (Hersey and Blanchard, 1974, 1982) perceived by staff members, and job satisfaction in terms of work, pay, opportunities for promotion, supervision style, relationship with coworkers-workers-workers-workers, and job in general according to the Job Satisfaction theory developed by …

Detection Of Deception In Law Enforcement Applicants: A Preliminary Investigation, Randy Borum, Harley Stock

Mental Health Law & Policy Faculty Publications

Using the MMPIand the IPI, the present study examined the differences in psychometric defensiveness between two groups of law enforcement applicants: applicants identified as being deceptive and a comparison group of candidates for whom no deception was indicated. Significant differences were found on the traditional validity (minimization) scales for both instruments as well as several supplemental scales and indexes from the MMPI. A new index (Es-K) from the MMPI showed a highly significant difference between groups and good classification accuracy. The results suggest that deceptive applicants show more defensiveness on psychometric testing and that test results may assist in raising …

Self-Control And Choice In Children: Effects Of Food Magnitude And Reinforcer Delay, Ellen Lee Sharenow

Dissertations

The present research was designed to replicate and extend earlier studies with humans and nonhumans in the area of self-control. A discrete trial, within-subject experimental design over multiple sessions, with food as the reinforcer, was used. Instructions did not describe contingencies of reinforcement Subjects were preschool age children, a population that questionably possess the verbal repertoire capable of generating sophisticated tacting, or mediating behavior during long delays. Four experiments consisted of fixed-ratio, concurrent chain schedules with initial and terminal links. Initial links were forced trials, terminal links, choice trials. In Experiment I, the effects of differences in magnitude while holding …

Effects Of Familiarity With A Sample-Stimulus In Selection-Based Learning Of Verbal Behavior, Robert J. Wallander

Masters Theses

Selection-based verbal behavior involves indicating a stimulus in some way from a set of stimuli. Twenty undergraduates served as subjects in this study of familiarity with a sample stimulus in a selection-based paradigm. The study utilized twenty Japanese Kanji characters as the comparison stimuli to be selected. Half the subjects were presented English names of animals as sample stimuli and the other half of the subjects were presented Japanese Katakana symbols (which appear as little more than nonsense figures) as sample stimuli.

T-tests were performed on the average number of twenty-trial blocks needed to meet criterion (two consecutive blocks without …

Residential Options For The Institutionalized Chronically Mentally Ill: The Impact Of Psychosis On Choice, Richard James Stanek

Dissertations and Theses

Discharge planning for hospitalized chronically mentally ill usually involves only verbal descriptions of community residential options. Psychosis often impairs ability to conceptualize abstract information, and quality of the choice process may be poor without describing options in concrete form, i.e., using written descriptions and photographs. A random sample (N= 90) of Dammasch State Hospital (Wilsonville, Oregon) patient population, comprising persons diagnosed schizophrenic, schizoaffective, organic mental disorder, and bipolar, were assigned to three treatment groups, asked to rank six community residential options suited for them when they were ready to leave the hospital. The three treatment groups were presented the same …
