Effect of Task Appropriateness, Social Comparison, and Feedback on Female Goals, Performance, and Self-Confidence with a Motor Task (open access)

Effect of Task Appropriateness, Social Comparison, and Feedback on Female Goals, Performance, and Self-Confidence with a Motor Task

Lenney (1977) concluded that achievement gender differences were predicted by females' lower self confidence and expectancies in competitive situations, identifying three variables that mediated female self confidence in achievement situations, (1) task appropriateness. (2) social comparison, and (3) feedback. The present study manipulated all three mediating variables with 240 undergraduate 18-25 year old female subjects with the pursuit rotor task that requires tracking a moving (40 rpm's) white light with a hand-held stylus for 60 seconds. Response measurement was based upon time on target. Subjects were tested over five trials while setting goals for each trial. Females were randomly assigned to a male appropriate, female appropriate, or gender neutral task condition, a competition or alone condition, and to one of four feedback conditions (no feedback, feedback about own performance only, feedback about own performance that provided the perception that subject was performing better than an opponent and/or average on each trial, or feedback about own performance that provided the perception that subject was performing poorer than an opponent and/or average on each of the five trials). Results from the 2 (social comparison) X 3 (task appropriateness) X 4 (feedback) ANOVA were contradictory to previous findings (Corbin, 1981; Petruzzello & Corbin, …

"Beowulf": Myth as a Structural and Thematic Key (open access)

"Beowulf": Myth as a Structural and Thematic Key

Very little of the huge corpus of Beowulf criticism has been directed at discovering the function and meaning of myth in the poem. Scholars have noted many mythological elements, but there has never been a satisfactory explanation of the poet's use of this material. A close analysis of Beowulf reveals that myth does, in fact, inform its structure, plot, characters and even imagery. More significant than the poet's use of myth, however, is the way he interlaces the historical and Christian elements with the mythological story to reflect his understanding of the cyclic nature of human existence. The examination in Chapter II of the religious component in eighth-century Anglo-Saxon culture demonstrates that the traditional Germanic religion or mythology was still very much alive. Thus the Beowulf poet was certainly aware of pre-Christian beliefs. Furthermore, he seems to have perceived basic similarities between the old and new religions, and this understanding is reflected in the poem. Chapter III discusses the way in which the characterization of the monsters is enriched by their mythological connotations. Chapter IV demonstrates that the poet also imbued the hero Beowulf with mythological significance. The discussion in Chapter V of themes and type-scenes reveals the origins of …

Perceptions of Managers in Kuwait on the Role of the Multinational Corporations in Change in Kuwait (open access)

Perceptions of Managers in Kuwait on the Role of the Multinational Corporations in Change in Kuwait

The purpose of this study is to investigate the perceptions of managers in Kuwait (both Kuwaiti and non- Kuwaiti) on the effects of multinational corporations (MNCs) in Kuwait and whether these effects were beneficial. The problem motivating this study is the effects that MNCs have on the social, cultural, political, legal, economic, business, and technological environments of their host countries, especially in developing nations. This study is based on a survey of the perceptions of 1,344 managers in Kuwait on the role of MNCs in changes in Kuwait. A review of the literature on MNCs and their relationships with their host countries is provided. This review focuses on four major environmental dimensions (Social-Cultural, Political-Legal, Business-Economic, and Technological) that are affected by MNCs. The factor analysis performed for this study supports this classification of the dimensions in the environment. An English questionnaire was developed from the list of major items in each of these dimensions. An Arabic version was developed using a "double-translation method." Both the English and Arabic versions of the questionnaire were pilot tested. The instrument proved to be reliable and valid. The study utilizes a 2 x 3 block design, categorizing subjects by nationality (Kuwaiti, other Arab, others) …

Distractibility, Impulsivity, and Hyperactivity Measured by the Kaufman Assessment Battery for Children and Personality Inventory for Children (open access)

Distractibility, Impulsivity, and Hyperactivity Measured by the Kaufman Assessment Battery for Children and Personality Inventory for Children

Basic criteria for determination of Attention Deficit Hyperactivity Disorder (ADHD) include hyperactivity, impulsivity, and distractibility. Four scales of the Personality Inventory for Children have been found to be useful in the diagnosis of ADHD. Impulsivity and distractibility can affect scores on the Hand Movements, Number Recall, Word Order, Spatial Memory, Arithmetic, Riddles, and Matrix Analogies subtests of the Kaufman Assessment Battery for Children. Subjects were 100 children, aged six through 13 who were referred for psychological assessment. The purpose of this study was to determine if there was a correlation between scores on the four scales of the PIC and the designated subtest scores on the KABC. Four correlations were significant, but of low magnitude.

A Model for Predicting Bereavement Outcome in Widowhood (open access)

A Model for Predicting Bereavement Outcome in Widowhood

The present longitudinal study examined the effects and interactions of several variables thought to affect adjustment to conjugal bereavement. Questionnaires were administered to 147 conjugally bereaved subjects and to 46 persons bereaved of close relatives other than spouse. Independent variables included experienced competence (self-esteem, locus of control, coping self-efficacy, and prior coping strategies), impact of loss (anticipation and preventabillty of loss, centrality of relationship and life change), and perceived resources. All of the independent variables were found to be important predictors of adjustment in conjugal bereavement. However, hypothesized interactions among variables were generally not found. Experimental variables were better predictors of adjustment in conjugal bereavement than were demographic variables. Contrary to prediction, widowed subjects tended to become more lonely and showed increased bereavement adjustment difficulties over a six month period of time. However, post hoc analysis suggested that levels of adjustment do not decline over the long term in widowhood. The present study supports a view of widowhood as a multidimensional event, characterized by seemingly contradictory feelings, experiences, and behaviors.

Comparability of the WPPSI-R and the Stanford-Binet: Fourth Edition (open access)

Comparability of the WPPSI-R and the Stanford-Binet: Fourth Edition

The purpose of this study was to compare the performance of children on the Wechsler Preschool and Primary Scale of Intelligence-Revised (WPPSI-R) with their performance on the Stanford-Binet Intelligence Scale: Fourth Edition (SB:FE). One hundred and four children between 3 and 7 years of age were administered both tests. A moderate correlation was found between the WPPSI-R Full Scale IQ and the SB:FE Composite Score with a Pearson product-moment correlation of .46. This correlation suggests that the two tests are not interchangeable measures of children's intelligence. They may measure different, equally important aspects of intelligence. As both tests used are relatively new, the current findings should be considered one step in the accumulation of knowledge about the usefulness of the WPPSI-R.

A Cost-Benefit Analysis of the Implementation of Texas House Bill 72 in Selected Texas Public School Districts (open access)

A Cost-Benefit Analysis of the Implementation of Texas House Bill 72 in Selected Texas Public School Districts

This study was conducted to analyze the effect of implementation of Texas House Bill 72 on budgets of selected Texas public school districts and to ascertain educational benefits to students derived from implementation of the bill as perceived by superintendents. Questionnaires were sent to superintendents of the Region 10 Education Service Center to determine perceived educational benefits to students. A demographic data sheet provided information for classifying respondents by educational experience, superintendent experience, and district enrollment classifications. Sixty-two districts responded. Official public school budget data for each district were analyzed for fiscal years 1983 through 1986 as were data from the questionnaire. Overall statistical information was gleaned through CONDESCRIPTIVE. Mean total expenditures, mean total tax rate, and state fiscal aid data were compiled, tabulated, and reported for each enrollment classification and entire sample. In addition, a t-test between the difference of two independent means at a probability level of .05 was applied. The two independent means were the averages of data for the two years prior to and after implementation of the law for expenditures, tax rates, and state fiscal contributions. Data comparing local and state expenditures were compiled, tabulated, and reported for each group to compare local and state …

Validation of a Test Battery for the Selection of Driver Managers in a Trucking Organization (open access)

Validation of a Test Battery for the Selection of Driver Managers in a Trucking Organization

This study was a concurrent validation of a paper and pencil test battery used at a national trucking company. Forty-eight driver managers were rated by their immediate supervisors with the performance appraisal covering 12 dimensions of job behavior that was developed by the experimenter. The driver managers were also administered the Wesman Personnel Classification Test, the Watson-Glaser Critical Thinking Appraisal, and the California Psychological Inventory (CPI). A biographical information blank was also developed and validated. Most validity correlations were nonsignificant, with the exception of the Dominance scale r = .25 (p < .05), the Self-control scale r = -.25 (p < .05), the Communanlity scale r = .29 (p < .05), and the Flexibility scale r = -.39 (p < .05), with overall performance.

A Study of the Influences Upon Pre-Service Teachers' Pre-Planning, Lesson Planning, and Bases for Interactive Decision Making During Lesson Implementation (open access)

A Study of the Influences Upon Pre-Service Teachers' Pre-Planning, Lesson Planning, and Bases for Interactive Decision Making During Lesson Implementation

The primary objective of this study was to describe the influences upon pre-service elementary teachers' preplanning, lesson planning, and bases for interactive decision making during their lesson implementation. Six female volunteer pre-service elementary teachers from the teacher preparation program at the University of North Texas planned and taught three separate lessons in one of the following content areas-social studies, language arts, mathematics, science, and safety, at six different schools in the north Texas area. Each element of the lesson plans (18 total) was classified for analysis. Following the presentation of each lesson, the pre-service teachers were asked to use the repertory-grid technique to sort out five decisions from a series of lesson-implementation decisions which had been observed and recorded by the investigator. Then the six pre-service teachers were interviewed by the investigator using the stimulated recall technique. During the interview, each decision was discussed with the pre-service teachers, who responded to seven structural questions that probed their concerns, attitude, type of concerns, and number of concerns. The six pre-service elementary teachers possessed some ability to direct students in their classroom learning using activities and instructional knowledge. This enabled them to notice individual student performance and that of students in the …

Critical Expectations of Workers Undergoing a Major Change in the Workplace (open access)

Critical Expectations of Workers Undergoing a Major Change in the Workplace

In an effort to determine whether job satisfaction and expectations in a group of workers undergoing major change in the workplace differ from groups of workers not undergoing major change, data were collected from three groups of workers at the operator level in a major U.S. electronics manufacturing company. Two of the groups were not undergoing a major work redesign and served as control groups. A group undergoing the early stages of a major work redesign, characterized primarily by their formation into a self-managed work team, served as the experimental group. The experimental group and one control group were located at the same manufacturing plant, while the other control group was located at another plant. It was hypothesized that the group of workers undergoing change would differ in job satisfaction and that over time, the difference would grow. It was also hypothesized that the group undergoing change would have different expectations about the nature of their jobs in the future. Data were collected from members of the three groups using a modified version of Hackman and Oldham's (1980) Job Diagnostic Survey, with two administrations of the survey seven months apart. Data were analyzed using a 3 (Groups) X 2 (Perception: …

Sediment Bound Trace Metals in the White Rock Creek Watershed, Dallas and Collin Counties (open access)

Sediment Bound Trace Metals in the White Rock Creek Watershed, Dallas and Collin Counties

Areas were sampled in the White Rock Creek Watershed to examine sediment bound trace metal distributions and sorption relationships. A Kruskal-Wallis AOV found significant among area differences for most metals, and SNK-like multiple comparisons were used to group these areas. Kruskal-Wallis AOVs similarly found among area differences for sediment components that bind trace metals (Fe and Mn oxides and organic carbon) and physicochemical conditions that influence metal sorption (particle size and pH). Multiple correlation found numerous relationships among trace metals, sediment components, and physicochemical conditions. Statistical relationships indicate that metal partitioning to various sorption factors is metal specific. White Rock Creek Watershed trace metal concentrations are comparable to those in many urban watersheds.

I, Blavatsky: A One-Act Opera (open access)

I, Blavatsky: A One-Act Opera

I, Blavatsky is a one-act opera based on the life of Helena Petrovna Blavatsky, a nineteenth-century Russian princess and co-founder of a religious organization called the Theosophical Society. The libretto, by the composer, involves a cast of three principal soloists and minor roles for six more singers who are also participants in a small chorus. The text format features free verse alternating with regular, rhymed strophes. Accompaniment is provided by a piano. Melodic structure combines some nineteenth-century Romantic idioms with twentieth-century style. Most of the melodic and harmonic material was intuitively composed to express the text. Rhythmic and stylistic contrasts are accomplished in the representation of the extensive travels of the main character. Stage directions involve a stylized set, several scenes requiring minimal set changes, magical effects to represent that facet of Blavatsky's life, and onstage costume changes for several characters. Approximate duration is one hour.

Development and Validation of a Ramping Treadmill Protocol for the On-Line Measurement of Four Aerobic Parameters (open access)

Development and Validation of a Ramping Treadmill Protocol for the On-Line Measurement of Four Aerobic Parameters

Previously, Whipp et. al. (J. Appl. Physiol.: Respirat. Environ. Exerc. Physiol. 50(1):217-221, 1981) demonstrated the feasibility of determining four parameters of aerobic function, identified as maximum oxygen uptake (μVO_2), VO_2 at anaerobic threshold (θan), the time constant for oxygen uptake kinetics (rVO_2) and work efficiency (η), using a short duration ramped bicycle ergometer exercise test. Because of the importance of being able to measure these parameters on a variety of measurement instruments a short duration ramping treadmill protocol has been developed. The ability of this protocol to determine the four aerobic parameters has been validated against conventional methods. The results of this investigation indicate that μVO_2, θan, rVO_2 and, η may be obtained from a single, short-duration ramping treadmill test.
