Increasing Differentiation on Vocational Assessments among Gifted High School Students (open access)

Increasing Differentiation on Vocational Assessments among Gifted High School Students

Multipotentiality makes career counseling with gifted students difficult. High-flat vocational profiles give the impression that gifted students can develop a wide range of abilities to an equally high level. High-flat vocational profiles may be due to assessments that consider abilities and disregard interests and values, and ceiling effects from the use of age-appropriate, rather than cognitively-appropriate measures. Subjects included 170 gifted students from a residential, early college entrance program (M=15.9 yrs., SD=.361). Subjects completed the Scholastic Aptitude Test, Self-Directed Search, and Study of Values. McNemar's Test of Correlated Proportions shows the proportion of multipotential profiles decreases significantly when cognitively-appropriate measures of interests and values are considered, in addition to abilities. Pearson Chi-square shows no ethnic differences.

Knowing is Seaing: Conceptual Metaphor in the Fiction of Kate Chopin (open access)

Knowing is Seaing: Conceptual Metaphor in the Fiction of Kate Chopin

This paper examines the metaphoric structures that underlie Chopin's major novel, The Awakening, as well as those underlying selected short stories. Drawing on the modern theory of metaphor described by Mark Turner, George Lakoff, and Mark Johnson, the author argues that conceptual metaphors are the structural elements that underlie our experiences, thoughts, and words, and that their presence is revealed through our everyday language. Since these conceptual structures are representative of human thought and language, they are also present in literary texts, and specifically in Chopin's texts. Conceptual metaphors and the linguistic forms that result from them are so basic a part of our thinking that we automatically construct our utterances by means of them. Accordingly, conceptual metaphor mirrors human thought processes, as demonstrated by the way we describe our experiences.

A Unifying Version Model for Objects and Schema in Object-Oriented Database System (open access)

A Unifying Version Model for Objects and Schema in Object-Oriented Database System

There have been a number of different versioning models proposed. The research in this area can be divided into two categories: object versioning and schema versioning. In this dissertation, both problem domains are considered as a single unit. This dissertation describes a unifying version model (UVM) for maintaining changes to both objects and schema. UVM handles schema versioning operations by using object versioning techniques. The result is that the UVM allows the OODBMS to be much smaller than previous systems. Also, programmers need know only one set of versioning operations; thus, reducing the learning time by half. This dissertation shows that UVM is a simple but semantically sound and powerful version model for both objects and schema.

A Structural Approach to Four Theories of Group Development (open access)

A Structural Approach to Four Theories of Group Development

The goal of this study was to attempt to develop a classification scheme that systematically related individual behavior, interpersonal behavior, and group interactions for the purpose of using the resulting classification scheme to evaluate theories of group development proposed by Bion, Bennis and Shepard, Bales, and Tuckman and Jensen. It was assumed that theorists' presuppositions about the structure of groups might influence their theories. Using a qualitative process of analysis, a structural classification scheme (SCS) was developed based upon transformative and generative rules, utilizing the General System Theory subsystem process of self-regulated boundary operations. The SCS protocol was employed to categorize and compare the theories of group development proposed by Bion, Bennis and Shepard, Bales, and Tuckman and Jensen. The resulting categorization of theories indicated that relationships existed among and between a group's structural properties, the complexity and type of communication connections among and between group members, and the size of the group. In addition, a common structural relationship was demonstrated to exist among and between individual, dyadic, and triadic group forms. A similar structural relationship was also speculated to exist between groups of any size. It was concluded that a structural approach to groups may offer insight to group …

Detection of Malingering on Raven's Standard Progressive Matrices and the Booklet Category Test (open access)

Detection of Malingering on Raven's Standard Progressive Matrices and the Booklet Category Test

The capacity of Raven's Standard Progressive Matrices (SPM) and the Booklet Category Test (BCT) to discriminate between groups of brain-injured, simulated malingering, and normal participants was investigated in this study. Exploratory analyses were also conducted to examine the differences between groups categorized as sophisticated and naive fakers. Clinical decision rules and discriminant function analyses were utilized to identify malingerers. Clinical decision rules ranged in hit rates from 41% to 78%, in sensitivity from 2% to 100%, and in specificity from 86% to 100%. Discriminant functions ranged in hit rates from 81% to 86%, in sensitivity from 68% to 73% and in specificity from 82% to 87%. Overall, the least helpful detection method examined was below chance responding on either measure, while the most efficient was gross errors for SPM.

Subcloning and Nucleotide Sequence of the xylO/PUWCMA Region from the Pseudomonas putida TOL Plasmid pDK1 (open access)

Subcloning and Nucleotide Sequence of the xylO/PUWCMA Region from the Pseudomonas putida TOL Plasmid pDK1

The TOL plasmids of Pseudomonas putida encode enzymes required for the oxidation of toluene and other related aromatic compounds. These genes are organized into two operons, the xylUWCMABN operon (upper), and the xylXYZLTEGFJQKIH operon (lower). Here we report the nucleotide sequence of a 7107 bp segment of the TOL pDK1 plasmid encoding the region just upstream of the "upper" operon through the genes encoding xylUWCMA. Sequence analysis, comparison of base-usage patterns, codon-usage patterns, and intergenic distances between genes help support the idea that the "upper" and "lower" operons have evolved independently in different genetic backgrounds and have only more recently been brought together in TOL and related catabolic plasmids.

A Study of the Influence of Kenneth Cooper's Work on the Teaching of Wellness and Fitness in Physical Education Programs in 2-Year Community Colleges in the United States (open access)

A Study of the Influence of Kenneth Cooper's Work on the Teaching of Wellness and Fitness in Physical Education Programs in 2-Year Community Colleges in the United States

Kenneth H. Cooper is considered to be a noted scholar in the field of wellness and fitness. This study explored his contributions to the preventive medicine and wellness movement in community college physical education programs in the United States. It examined Cooper's influence on the development of preventive medicine and wellness from its inception and growth to its impact on changes and factors affecting curriculum in community college programs. A random sample of436 physical education division directors from the nation's 1,400 community colleges yielded a 62% survey response. For purposes of comparison, the sample was stratified into two regions taken fromeast and west of the Mississippi River. Chi-square analysis at the .01 level of significance found no difference between variables due to geographic region. The findings of this study indicate that Kenneth Cooper's contributions to preventive medicine and wellness in community college physical education curriculum are overshadowed by state and local governing bodies that are the force behind curricular development in the nation's 2-year community colleges. However, as an individual contributor, Cooper ranks highly in influencing the wellness and physical education curriculum primarily in the areas of aerobic exercise, physical fitness, and cardiovascular disease. The extent of Cooper's impact on …

Examining the Relationship between Variability in Acquisition and Variability in Extinction (open access)

Examining the Relationship between Variability in Acquisition and Variability in Extinction

Using the "revealed operant" technique, variability during acquisition and extinction was examined with measures of response rate and a detailed analysis of response topography. During acquisition, subjects learned to emit four response patterns. A continuous schedule of reinforcement (CRF) for 100 repetitions was used for each pattern and a 30 min extinction phase immediately followed. One group of subjects learned the response patterns via a "trial-and-error" method. This resulted in a wide range of variability during acquisition and extinction. Only one subject emitted a substantial amount of resurgent behavior. A second group of subjects was given instructions on what keys to press to earn reinforcers. This group had less variability in acquisition and extinction and resurgent responding was prevalent.

Minimality of the Special Linear Groups (open access)

Minimality of the Special Linear Groups

Let F denote the field of real numbers, complex numbers, or a finite algebraic extension of the p-adic field. We prove that the special linear group SLn(F) with the usual topology induced by F is a minimal topological group. This is accomplished by first proving the minimality of the upper triangular group in SLn(F). The proof for the upper triangular group uses an induction argument on a chain of upper triangular subgroups and relies on general results for locally compact topological groups, quotient groups, and subgroups. Minimality of SLn(F) is concluded by appealing to the associated Lie group decomposition as the product of a compact group and an upper triangular group. We also prove the universal minimality of homeomorphism groups of one dimensional manifolds, and we give a new simple proof of the universal minimality of S∞.

AIDS Preventative Behavior Among Taiwanese University Students (open access)

AIDS Preventative Behavior Among Taiwanese University Students

This study used the Health Belief Model to examine the predictors of AIDS preventive behavior. The independent variables were the variables of individual perception, modifying factors (psychological variables), and likelihood variables. The respondents, the Taiwanese students of the University of North Texas, were influenced both by Chinese sexuality and Western values in their AIDS-risk behavior. The results revealed that 90% of the respondents were misinformed on the availability of AIDS vaccine. In addition, a majority of the students were either abstaining from sex or practicing monogamy. Using Pearson's correlation coefficient and multiple regression analysis, this study found that the psychological variables rather than cognitive variables significantly influenced the respondents' AIDS preventive behavior. Finally, suggestions were made for future research on AIDS, and for AIDS preventive behavior campaigns.

Anti-Semitism and Der Sturmer on Trial in Nuremberg, 1945-1946: The Case of Julius Streicher (open access)

Anti-Semitism and Der Sturmer on Trial in Nuremberg, 1945-1946: The Case of Julius Streicher

The central focus of this thesis is to rediscover Julius Streicher and to determine whether his actions merited the same punishment as other persons executed for war crimes. Sources used include Nuremberg Trial documents and testimony, memoirs of Nazi leaders, and other Nazi materials. The thesis includes seven chapters, which cover Streicher's life, especially the prewar decades, his years out of power, and his trial at Nuremberg. The conclusion reached is that Streicher did have some influence on the German people with his anti-Semitic newspaper Der Sturmer, but it is difficult to ascertain whether his speeches and writings contributed directly to the extermination of the Jews in World War II or simply reflected and magnified the anti-Semitism of his culture.

A Comparative Analysis of Curricular Programs in Private, Public Choice, and Public Attendance-Zone Schools in San Antonio, Texas (open access)

A Comparative Analysis of Curricular Programs in Private, Public Choice, and Public Attendance-Zone Schools in San Antonio, Texas

The purpose of this study was to examine curricular programs in private, public choice, and public attendance-zone schools to determine whether differences exist among curricular programs in the three types of schools. The findings from the student survey data indicated that private school students reported their curriculum to be more challenging than public school students, but no other significant differences were noted. Findings from the teacher survey showed more positive results for private schools in indicators of a challenging curriculum, expectations of students, school climate, and external support than public schools. This study showed that of the types of schools examined, Catholic schools exhibited the most consistent and well written curriculum that reflected the four research questions. Future research needs to be done to establish whether these indicators of a challenging curriculum result in higher student achievement.

Nicotinic Acetylcholine Receptor α3 mRNA in Rat Visual System After Monocular Deprivation (open access)

Nicotinic Acetylcholine Receptor α3 mRNA in Rat Visual System After Monocular Deprivation

In situ hybridization was used to examine effects of monocular enucleation on nicotinic acetylcholine receptor subunit cc3 mRNA in the rat dLGNand visual cortex. After 28 days postoperative, there were no significant differences in α3 mRNA density between the contralateral (deprived) and ipsilateral (non-deprived) sides. The lack of obvious effects of visual deprivation on α3 mRNA density suggests that other factors, possibly intrinsic to dLGNand visual cortex, govern the postnatal expression of α3 mRNA.

The Process of Sharing Team Leadership : A Study of Key Leadership Behaviors and Who Exhibits Them

Using a manufacturing setting that is organized into self-managed teams, the current study identified and measured key leadership behaviors within the teams. Questions that were asked include: are some team leadership behaviors more critical to a team's level of functioning than other behaviors? and do successful self-managed teams rely on formal leadership to a lesser extent than members of less successful teams? These questions were asked in the context of leadership as a process, not an individual.

Out with the Old? Voting Behavior and Party System Change in Canada and the United States in the 1990's

This study has attempted to explain the dramatic challenges to the existing party system that occurred in Canada and the United States in the early 1990s. The emergence of new political movements with substantial power at the ballot box has transformed both party systems. The rise of United We Stand America in the United States, and the Reform Party in Canada prompts scholars to ask what forces engender such movements. This study demonstrates that models of economic voting and key models of party system change are both instrumental for understanding the rise of new political movements.

Forest Landscape Dynamics: a Semi-Markov Modeling Approach (open access)

Forest Landscape Dynamics: a Semi-Markov Modeling Approach

A transition model (MOSAIC) is used to describe forest dynamics at the landscape scale. The model uses a semi-Markov framework by considering transition probabilities and Erlang distributed holding times in each transition. Parameters for the transition model are derived from a gap model (ZELIG). This procedure ensures conceptual consistency of the landscape model with the fine scale ecological detail represented by the forest gap model. Spatial heterogeneity in the transition model is driven by maps of terrain with characteristics contained in a Geographic Information System (GIS) database. The results of the transition model simulations, percent cover forest type maps, are exported to grid-maps in the GIS. These cover type maps can be classified and used to describe forest dynamics using landscape statistics metrics. The linkage model-GIS enhances the transition model spatial analytical capabilities. A parameterization algorithm was developed that takes as input gap model tracer files which contain the percent occupation of each cover type through time. As output, the algorithm produces a file that contains the parameter values needed for MOSAIC for each one of the possible transitions. Parameters for the holding time distribution were found by calculating an empirical estimate of the cumulative probability function and using a …

Effects of Performance Levels of Subject Matter Experts on Job Analysis Outcomes (open access)

Effects of Performance Levels of Subject Matter Experts on Job Analysis Outcomes

Much research has been undertaken to determine how Subject Matter Expert characteristics affect job analysis outcomes. The current study seeks to discover if performance levels are related to current incumbents ratings of their positions. A group of 114 corporate associates, from two administrative positions, served as Subject Matter Experts (SME) for this study. Separate job analyses for each position were conducted using the Job Analysis Task Checklist. The results for each job were analyzed to determine if SME performance levels affected job analysis outcomes. The results for both jobs showed that there were very few differences in job analysis results as a function of SME performance levels.
