Immediate and generalized effects of one component (Stay Close Tool) of a behavioral parenting curriculum.

Immediate and generalized effects of one component (Stay Close Tool) of a behavioral parenting curriculum.

Date: May 2008
Creator: Greenspan, Michelle S.
Description: The Essential Tools for Positive Behavior Change is a behavioral parenting curriculum that is currently being disseminated throughout the state and Florida and is now being utilized in Texas to teach parents who are at risk or are founded of abuse and neglect. Research on the curriculum thus far has focused on large scale outcomes, skill acquisition of caregivers during analog role-play assessments, and scores on a written quiz. Little research has focused on generalization of classroom performance to the home. The measurement systems that have been used to evaluate positive outcomes also were in need of improvement. The current study was designed to determine whether teaching a component (Stay Close) to typical parents resulted in immediate improvements in written exam scores and on a role-play assessment and if those skills could be seen in a home setting. The results indicated that small improvements were seen across quiz scores in all but one family and some improvements across behavior was seen in both the role-play and home observations. Additionally, a reliable measurement system was created that captured both home observations and role-play assessment data.

Immediate and Subsequent Effects of Fixed-Time Delivery of Therapist Attention on Problem Behavior Maintained by Attention

Immediate and Subsequent Effects of Fixed-Time Delivery of Therapist Attention on Problem Behavior Maintained by Attention

Date: August 2009
Creator: Walker, Stephen Frank
Description: The purpose of the current study was to investigate the immediate and subsequent effects of fixed-time attention on problem behavior maintained by therapist attention utilizing a three-component multiple-schedule design. The treatment analysis indicated that fixed-time attention produced a significant immediate decrease in the frequency of physically disruptive behavior (PDB), represented by low frequencies of PDB in Component 2, as well as a continued subsequent effect, represented by lower frequencies of problem behavior in Component 3 when compared to Component 1. The possible behavioral mechanisms responsible for the observed suppression in Component 2 of the treatment analysis are discussed. Evidence of behavioral contrast was observed in Components 1 and 3 of the treatment analysis in conditions in which Component 2 contained a fixed-time schedule of stimulus delivery. In addition, limitations and future research are outlined.

Immediate and subsequent effects of fixed-time food presentations on automatically maintained mouthing.

Immediate and subsequent effects of fixed-time food presentations on automatically maintained mouthing.

Access: Use of this item is restricted to the UNT Community.
Date: December 2001
Creator: Simmons, Jason N.
Description: Several studies have demonstrated that fixed-time (FT) schedules of stimulus delivery can function to reduce a variety of behaviors. The purpose of this study was to evaluate the immediate and subsequent effects of FT food deliveries on mouthing. In Phase 1, a preference assessment showed that caramel popcorn, chocolate cookies and pretzels were highly preferred food items. Thus, providing the basis for use of food items during treatment. In Phase 2, a functional analysis showed that mouthing was a nonsocially maintained problem behavior. Phase 3 demonstrated the use of FT schedules of food deliveries as treatment for nonsocially maintained mouthing. Results indicated that FT schedules of food significantly reduced mouthing. In addition, levels of mouthing observed during post-FT observations were reliably lower than pre-FT observations. Treatment effects, operative mechanisms responsible for the treatment effects and the experimental arrangement used to investigate varying FT schedules are discussed.

Immediate and subsequent effects of response blocking on self-injurious behavior.

Immediate and subsequent effects of response blocking on self-injurious behavior.

Date: August 2006
Creator: Atcheson, Katy
Description: Abstract In many institutional settings, blocking, response restriction (e.g., restraint, protective equipment), and re-direction procedures are used extensively as intervention for self-injurious behavior (SIB) and other forms of problem behavior. In the current study, a three component, multiple-schedule analysis was used to examine the immediate and subsequent effects of blocking on SIB that persisted in the absence of social reinforcement contingencies. During the first and third components the participant was in the room, alone, with no social consequences for SIB. During the second component (response restriction) the therapist sat in the room with the participant and blocked occurrences of SIB. Results indicated that, although blocking was effective in decreasing SIB while it was being implemented, subsequent effects were idiosyncratic across participants. Evidence of increased levels of SIB following blocking was observed for some participants.

Immediate and subsequent effects of response-independent food delivery on problem behavior maintained by food.

Immediate and subsequent effects of response-independent food delivery on problem behavior maintained by food.

Date: May 2008
Creator: Cherryholmes, Lauren A.
Description: The immediate and subsequent effects of response-independent food delivery on problem behavior maintained by food were investigated. A functional analysis indicated that the participant's problem behavior was maintained by tangible (food) reinforcement. In a subsequent analysis, each occurrence of problem behavior produced a bite of wafer in the first and third components of mixed and multiple schedules, while either response-independent food or extinction was presented in the second component. Dense and lean schedules of food delivery were assessed. Results indicated that a very dense schedule of food nearly eliminated problem behavior, a very lean schedule of food and extinction produced substantial decreases in problem behavior, and intermediate schedules did not decrease problem behavior. Response patterns were differentiated across mixed and multiple schedule arrangements, with signaled changes in the schedules (multiple schedule) generally showing more immediate and sustained effects throughout the intervention component. Implications for interpretations of the effects of the intervention are discussed.

Immunity for New Mexico Public School Districts and the 1978 Tort Claims Act

Immunity for New Mexico Public School Districts and the 1978 Tort Claims Act

Date: August 2014
Creator: Herauf, Todd J.
Description: In a 3-year timeframe, nearly 800 student negligence suits were filed, and most involved some claim of personal injury. Despite heightened public attention of negligence lawsuits against school districts and their employees, an empirical study of court decisions revealed that the volume of litigation against school districts remained steady from 1990 to 2005, the majority of cases were ruled in favor of the school district employees, and government and official immunity were most often the basis for these rulings. Researchers have concluded that immunity laws are strong in the United States, although they vary by state in their application. However, a primary recommendation was that, because of the misconception of a lack of immunity for public school employees, a comprehensive study on governmental and official immunity is needed. This dissertation employed legal research, analysis, and methodology to engage in a comprehensive investigation of teacher immunity in the four southern states of Texas, Oklahoma, Mississippi, and New Mexico. Of central concern to this dissertation was the Tort Claims Act of 1978 from the State of New Mexico. The Tort Claims Act is the vehicle by which immunity is granted to public school employees. Court findings over the last 35 years point ...

Immunocompetence in the AKR Mouse

Immunocompetence in the AKR Mouse

Date: August 1976
Creator: Dunton, Helen
Description: A model for the study of the relationship of immunity to cancer is found in AKR mice which harbor Gross virus. This genetically transmitted virus is present in a latent form for months before it spontaneously induces leukemia. Many investigators have demonstrated near normal humoral responses, but abnormal cellular immunity in the preleukemic animal. With increasing age, pathology of the disease is expressed, reflecting diminished immunity. In this study, the ontogeny of humoral antibodies of AKR/J and SWR/J mice was assayed by microagglutination techniques in response to thymus-independent, thymus-dependent, and solubilized antigens. Simultaneous injections of thymusdependent and -independent antigens provided data suggesting an impaired humoral response in the AKR mouse.

Immunohistochemical characterization of neuronal cilia in the rat central nervous system.

Immunohistochemical characterization of neuronal cilia in the rat central nervous system.

Date: May 2002
Creator: Hughes, Rhome
Description: An anti-G"11 antibody was used to label neuronal cilia throughout the rat central nervous system. Immunoreactive cilia were observed in every examined region of the rat CNS, but not in monkey or mouse tissue. Antibodies to G"q and G"q/11 failed to label cilia. Immunoreactive cilia were observed as early as postnatal day 0 in spinal tissue, and postnatal day 3 in hypothalamic tissue. There was a statistically significant negative correlation between a region's mean cilium length and that region's distance to the nearest ventricle; regions nearest ventricles were those with the longest cilia. This correlation suggests neuronal cilia may function as chemosensors, detecting substances as they move out from the cerebrospinal fluid and into the extracellular space of the brain.

Immunohistochemistry of the Gills of the Channel Catfish Ictalurus Punctatus: Cells and Neurochemicals That May Be Involved in the Control of Cardioventilatory Reflexes

Access: Use of this item is restricted to the UNT Community.
Date: December 2013
Creator: Oden, David S.
Description: In teleost fishes the neurochemicals involved in sensing and responding to hypoxia are unresolved. Serotonergic branchial neuroepithelial cells (NECs) are putative O2 chemoreceptors believed to be homologous to the neural crest (NC) derived APUD (amine-precursor uptake and decarboxylation) pulmonary NECs and carotid body type-1 glomus cells. Branchial NECs contain serotonin (5-HT), thought to be central to the induction of the hypoxic cardioventilatory reflexes. However, application of 5-HT in vivo does not elicit cardioventilatory reflexes similar to those elicited by hypoxia. But previous in vitro neural recordings from glossopharyngeal (IX) afferents innervating O2 chemoreceptors in the trout gill show the same discharge response to hypoxic conditions as does that of acetylcholine (ACh) application. This evidence strongly supports the cholinergic hypothesis of chemoreceptor impulse origin rather than a serotonergic-induced impulse origin model. We therefore hypothesized that NECs contain ACh among other neurochemicals in cells belonging to the APUD series. Although serotonergic branchial NECs did not colocalize with ACh using immunohistochemical methods, several populations of ACh and/or tyrosine hydroxylase (TH) (catecholaminergic) positive, dopamine (DA) negative, cells were found throughout the second gill arch of the channel catfish Ictalurus punctatus. In addition, the NC derivation marker zn-12 labelled the HNK-1-like epitope (Human natural killer) ...

The Impact of a Community College Teacher Education Program on the Success Rate of Minority Teacher Certification Students

The Impact of a Community College Teacher Education Program on the Success Rate of Minority Teacher Certification Students

Date: May 2013
Creator: Perkins, Britine Lynee
Description: The relationship between the mission of community colleges and the increasing teacher shortage has become more transparent as many community colleges have implemented teacher education programs to address community needs, the shortage of qualified teachers, and the lack of diversity among teachers. As the community college's teacher education role has increased, many community colleges have responded by adding associate of arts degrees and certificate programs specific to teacher education to tackle the shortage of teachers and the lack of diversity among teachers in the nation's classrooms. The purpose of this study was to examine the effectiveness of one community college's pre-service teacher education program in transferring minority students to a university teacher education program and the likelihood of the students graduating with both bachelor's degrees and teacher certification. This longitudinal ex post facto causal-comparative mixed methods case study involved tracking a cohort of minority students over a 6-year period. Data were gathered from existing teacher education program records for native and transfer students at one community college and two four-year institutions. Unstructured interviews were conducted with administrators over the community college's program. For data analysis, ?2 and Phi Coefficients were conducted to compare the minority students' university transfer and graduation ...

The Impact of a Father and Son on Texas: Isaac Van Zandt and Khleber Miller Van Zandt

The Impact of a Father and Son on Texas: Isaac Van Zandt and Khleber Miller Van Zandt

Date: December 2006
Creator: Cranz, Jane Sloan
Description: Isaac Van Zandt and his son Khleber Miller Van Zandt were instrumental figures in the growth of Texas and the development of the town of Fort Worth, Texas. Isaac Van Zandt was one of the main members of the delegation from Texas to the United States who negotiated for annexation. He also played a major part in the Texas Constitutional Convention of 1845 and made a run for governor before his death in 1847. His son, Khleber Miller Van Zandt was a Confederate soldier and businessman who saw something in the outpost of Fort Worth that was worth developing. Along with an influential group of other businessmen he was a part of every major development that occurred in Fort Worth until his death in 1930. Both Van Zandts' roles are discussed and the importance of their actions is brought to light.

Impact of a Genetically Engineered Probiotic Therapy and Igf-1 Genomics in the Pahenu2 Mouse Model of Pku

Impact of a Genetically Engineered Probiotic Therapy and Igf-1 Genomics in the Pahenu2 Mouse Model of Pku

Date: December 2015
Creator: Durrer, Katherine Elaine
Description: Absence of functional phenylalanine hydroxylase results in phenylketonuria (PKU). Viable treatments remain few, expensive and secondary conditions such as osteopenia occur in most PKU patients. Objective 1: Given the recently described roles of gut microbes to aid host digestion, an orally administered genetically engineered probiotic as the delivery vehicle for enzyme replacement therapy was created. The engineered probiotic, pHENOMMenal, produced phenylalanine ammonia lyase with significant production of trans-cinnamate (phenylalanine cleavage product) in vitro and resulted in a reduction of 515 μM in blood phenylalanine when fed to PKU animals for 14 days (from 2307µM ± 264µM to 1792µM ± 261µM, n = 6, P < 0.05). The control probiotic produced no change in blood phenylalanine. Thus, pHENOMMenal treatment in PKU mice demonstrated engineered microbes could compensate for a metabolic deficiency of the host. Objective 2: Evaluate the PAHenu2 mouse model of PKU for a genetic discrepancy causing ocular enlargement and delayed development observed only after the PAHenu2 mutation was crossed to the C57BL/6J mouse. When compared to healthy littermates, ELISA indicated a consistent but insignificant decrease in plasma IGF-1 and an increase in ocular IGF-1 in PKU animals. SNP screening demonstrated a differential inheritance of IGF-1 alleles in healthy and ...

The impact of a junior high school leadership program on the academic success and leadership development of at-risk students.

The impact of a junior high school leadership program on the academic success and leadership development of at-risk students.

Date: May 2003
Creator: Reed, Janice
Description: The primary purpose of this study was to determine the impact of a junior high school leadership program on the academic success and leadership development of its at-risk student participants. A secondary purpose, based on impact, was to evaluate the program as a potential school-based model for adolescent at-risk intervention. The leadership program investigated in this study is unique in three ways. First, the program is in a magnet school and the student population is heterogeneously mixed as to ethnicity and socio-economic status. Second, enrollment is open to all students. Third, its curriculum goals meet research-based criteria for effective intervention practices and leadership development. Academic success indicators associated with at-risk students included achievement, conduct, attendance, and school engagement. Leadership development indicators included leadership practices students had experienced and leadership positions students had held. The design of this post hoc study was the comparison of two groups of high school students who qualified as "at-risk" during their junior high years. Data collection included district or campus reports for cumulative attendance rates, grade point averages, and conduct demerits, as well as student survey responses for school activities, leadership practices experienced, and leadership positions held. Results of multivariate and univariate inferential analyses show ...

The Impact of a Mentoring Program on the Self-Esteem of College-Age Women

The Impact of a Mentoring Program on the Self-Esteem of College-Age Women

Date: August 1997
Creator: Higgins, Lynda Kay Burton
Description: The fact that girls and women suffer a loss of self-esteem disproportionate to boys and men is without argument. There are an increasing number of books, magazine articles, and resource kits being made available to begin to comprehensively address the issue with young girls. However, less effort is being directed toward the older adolescent, the college-age woman. The problem with which this study was concerned was that of determining the impact of a mentoring program on the self-esteem of college-age women. The Multidimensional Self-Esteem Inventory (MSEI) was administered as a pre- and posttest, to 40 sophomore women, 20 of whom were in a control group and 20 who participated in the structured mentoring program. Using the MSEI, it was possible to gain statistically significant data which indicated that the self-esteem of the women could be positively impacted as a result of the mentoring experience. In addition to the instrument, the participants kept journals about their mentoring experience. Therefore, this research was able to report both qualitative and quantitative findings. The findings regarding the control group were not statistically significant for any of the 11 characteristics on the inventory. The findings from the mentored group however, were determined to be statistically ...
