Identification of Ego States and Early Parent-Child Relationships

Description: The purpose was to verify ego states as objectively identifiable phenomena and the influence of early parent-child relationships on their identification using an audio tape of recorded examples of ego states, Thompson's Ego State Tape (EST), and the Roe-Siegleman Parent-Child Relations Questionaire (PCR). No relationship was found between SAT scores and scores on the EST, nor between PCR and EST scores. It was concluded that possibly (1) no relationship existed between how children perceive their parents and the identification of ego states, and (2) that the PCR might not be sampling child rearing practices relevant to the identification of ego states.

Identification of Endogenous Substrates for ADP-Ribosylation in Rat Liver

Description: Bacterial toxins have been shown to modify animal cell proteins in vivo with ADPR. Animal cells also contain endogenous enzymes that can modify proteins. Indirect evidence for the existence in vivo of rat liver proteins modified by ADPR on arginine residues has been reported previously. Presented here is direct evidence for the existence of ADP-ribosylarginine in rat liver proteins. Proteins were subjected to exhaustive protease digestion and ADP-ribosyl amino acids were isolated by boronate chromatography.

Identification of environmental determinants of behavior disorders through functional analysis of precursor behaviors

Description: Methods for the determining the functional properties of problem behaviors are necessary for the design of successful treatments. Many of the currently utilized methodologies are chosen based on their speed, ease of application or for the perceived risk-reduction they afford. However, when thoroughly analyzed many of these methods fall short of their intended purpose. The current study attempted to assess dangerous problem behavior through a functional assessment of functionally related precursor behaviors during analog sessions. Results indicate that for three participants, placing the reinforcing contingencies on these related precursor behaviors produced differentiated outcomes during the assessment. These outcomes matched the outcomes of assessments of the more dangerous problem behaviors.

Identification of Genes Involved in Flocculation by Whole Genome Sequencing of Thauera Aminoaromatica Strain Mz1t Floc-defective Mutants

Description: Thauera aminoaromatica MZ1T, a floc-forming bacterium isolated from an industrial activated sludge wastewater treatment plant, overproduces exopolysaccharide (EPS) leading to viscous bulking. This phenomenon results in poor sludge settling and dewatering during the clarification process. To identify genes responsible for bacterial flocculation, a whole genome phenotypic sequencing technique was applied. Genomic DNA of MZ1T flocculation-deficient mutants were subjected to massively parallel sequencing. The resultant high-quality reads were assembled and compared to the reference genome of the wild type genome. We identified nine nonsynonymous mutations and one nonsense mutation putatively involved in EPS biosynthesis. Complementation of the nonsense mutation located in an EPS deacetylase gene restored the flocculating phenotype. The FTIR spectra of EPS isolated from the wild-type showed reduced C=O peak of the N-acetyl group at 1665 cm-1 as compared to the spectra of MZ1T floc-deficient mutant EPS, suggesting that the WT EPS was partially deacetylated. Gene expression analysis also demonstrated the deacetylase gene transcript increased before flocculation occurred. The results suggest that the deacetylation of MZ1T EPS is crucial for flocculation. The information obtained from this study will be useful for preventing viscous bulking and wastewater treatment system failure, and may have potential applications in the biotechnology sector for the controlled removal of cells.

Identification of highly gifted 5- and 6-year-old children: Measures to predict academic achievement.

Description: Studies indicate the educational needs of highly gifted students are best met through accelerated learning. It is difficult to recognize very young children that are suited for an accelerated curriculum because younger students frequently lack school records or portfolios used to identify gifted students. This study examined the accuracy of cognitive ability and achievement tests in predicting academic achievement by the end of second grade, correlating test results and final grade averages collected from sixteen children ages five to six who entered a public school program for high-ability learners in kindergarten. A multiple regression analysis indicated the Wechsler Preschool and Primary Scale of Intelligence produced the highest mean IQ score and a strong correlation with reading achievement. The Wechsler Individual Achievement Test contributed in small part to the prediction of academic achievement. The Naglieri Nonverbal Ability Test and the Kaufman Brief Intelligence Test-Second Edition had negative correlations with final grade averages, indicating they are not predictors of academic achievement for these students.

Identification of Hox Genes Controlling Thrombopoiesis in Zebrafish

Description: Thrombocytes are functional equivalents of mammalian platelets and also possess megakaryocyte features. It has been shown earlier that hox genes play a role in megakaryocyte development. Our earlier microarray analysis showed five hox genes, hoxa10b, hoxb2a, hoxc5a, hoxc11b and hoxd3a, were upregulated in zebrafish thrombocytes. However, there is no comprehensive study of genome wide scan of all the hox genes playing a role in megakaryopoiesis. I first measured the expression levels of each of these hox genes in young and mature thrombocytes and observed that all the above hox genes except hoxc11b were expressed equally in both populations of thrombocytes. hoxc11b was expressed only in young thrombocytes and not in mature thrombocytes. The goals of my study were to comprehensively knockdown hox genes and identify the specific hox genes involved in the development of thrombocytes in zebrafish. However, the existing vivo-morpholino knockdown technology was not capable of performing such genome-wide knockdowns. Therefore, I developed a novel cost- effective knockdown method by designing an antisense oligonucleotides against the target mRNA and piggybacking with standard control morpholino to silence the gene of interest. Also, to perform knockdowns of the hox genes and test for the number of thrombocytes, the available techniques were both cumbersome or required breeding and production of fish where thrombocytes are GFP labeled. Therefore, I established a flow cytometry based method of counting the number of thrombocytes. I used mepacrine to fluorescently label the blood cells and used the white cell fraction. Standard antisense oligonucleotide designed to the central portion of each of the target hox mRNAs, was piggybacked by a control morpholino and intravenously injected into the adult zebrafish. The thrombocyte count was measured 48 hours post injection. In this study, I found that the knockdown of hoxc11b resulted in increased number of thrombocytes and knockdown of hoxa10b, ...

Identification of Predictors of Success in Individualized Computer Courses

Description: This study provides a rationale for advising students on whether to enroll in individualized/self-paced computer courses. It identifies seven factors that have a significant correlation with success in an individualized computer course. The sample comprises all the students enrolled in individualized computer courses at Lee College, Baytown, Texas in the spring semester of 1988. Students completed a survey to determine whether they had previous computer experiences, whether they operated with a level of introvert personality characteristics, and whether the individualized computer course was their first choice. Students completed a learning style inventory and a score was determined using the items relating to individualized computer studies. Data collected in the Lee College records office included high school percentile rank, standardized reading score, standardized mathematics score, college hours completed, course withdrawals, and age. The following seven factors were shown by the data to have a significant correlation with a final grade (in order of decreasing significance): (a) learning style inventory, (b) high school percentile, (c) standardized mathematics score, (d) standardized reading score, (e) previous computer experience, (f) number of college hours, and (g) age. The following three factors were shown by the data to have no significant correlation with a final grade: (a) course withdrawals, (b) degree of personality introversion, and (c) the individualized computer course as first choice. The findings substantiate the hypothesis that success in an individualized computer course might be attributed to certain factors, and once identified, these factors can be used in advising students. Advisors should use as many of the seven factors (identified as significant), as possible in helping students choose between individualized and traditional computer courses.

Identification of Remote Leadership Patterns in Academic and Public Libraries

Description: Seminal works on leadership, including those in librarianship define a traditional model of interaction between leaders and followers without reference to the information technology-driven environment. In addition, remote leadership indicates a different model from the traditional model, one that is focused on the interaction of leaders and their staff through digital technology. Although leaders still use face-to-face interaction, due to varied work schedules or job responsibilities, they also recognize the need to lead employees remotely. Leadership studies in library literature have not addressed how library leaders use information technology to lead employees remotely, nor have these studies addressed remote leadership and remote employees, except for some articles on telecommuting. As a result, this research was conducted to address this gap, providing an exploratory foundation of emergent patterns of remote leadership with its associated leadership dimensions rooted in personality traits, behaviors, and skills. Quantitative and qualitative data were obtained from a small sample size of academic and public-library leaders in the United States who participated in a Web-based survey designed specifically for this study, limiting generalizations. Factor analysis was the principal methodology used to obtain findings. Its composite factor scores were also used in the t-test and chi-square analyses. This study identifies some emergent patterns of remote leadership in the library and information-science field, exploring whether library leaders use information technology to be effective remote leaders in a technology-driven environment, and whether existing leadership attributes could be identified as part of the remote-leadership model. Because this study's findings indicated that library leaders are not quite the traditional leader but are not fully integrated into remote leadership, it becomes apparent that they would function with a blend of both face-to-face and electronic interactions, due to the nature of library work. Additionally, this research revealed underlying issues and challenges faced by library leaders ...

Identification of Three Symbiosome Targeting Domains in the MtENOD8 Protein and Cell-to-cell MtENOD8 mRNA Movement in Nodules

Description: The model legume, Medicago truncatula, is able to enter into a symbiotic relationship with soil bacteria, known as rhizobia. This relationship involves a carbon for nitrogen exchange in which the plant provides reduced carbon from photosynthesis in exchange for reduced, or “fixed” atmospheric nitrogen, which allows the plant to thrive in nitrogen depleted soils. Rhizobia infect and enter plant root organs, known as nodules, where they reside inside the plant cell in a novel organelle, known as the symbiosome where nitrogen fixation occurs. the symbiosome is enriched in plant proteins, however, little is known about the mechanisms that direct plant proteins to the symbiosome. Using the M. truncatula ENOD8 (MtENOD8) protein as a model to explore symbiosome protein targeting, 3-cis domains were identified within MtENOD8 capable of directing green fluorescent protein (GFP) to the symbiosome, including its N-terminal signal peptide (SP). the SP delivered GFP to the vacuole in the absence of nodules suggesting that symbiosome proteins share a common targeting pathway with vacuolar proteins. a time course analysis during nodulation indicated that there is a nodule specific redirection of MtENOD8-SP from the vacuole to the symbiosome in a MtNIP/LATD dependent manner. GFP expression by the MtENOD8 promoter revealed spatial discrepancy between promoter activity and protein localization. in situ localization of MtENOD8 mRNA showed localization to infected cells, where the protein is found, suggesting mRNA cell-to-cell movement. Expression of MtENOD8 in Arabidopsis showed that the SP did not direct GFP to the vacuole indicating that vacuolar targeting of MtENOD8’s SP may be legume specific. Taken together, the research presented here indicates that the MtENOD8 symbiosome protein has evolved redundant domains for targeting, which has part of a common pathway with vacuolar proteins. Observed spatial discrepancy between the MtENOD8 promoter and protein shows additional mechanisms of gene regulation through cell-to-cell mRNA ...

Identifying AD/HD subtypes using the cognitive assessment system and the NEPSY

Description: The purpose of this study was to examine the ability of the Cognitive Assessment System (CAS) and the NEPSY, A Developmental Neuropsychological Assessment, to differentiate between the subtypes of Attention Deficit/ Hyperactivity Disorder (AD/HD). The CAS and NEPSY are neuropsychological instruments which provide norms for AD/HD children in general. This study examined the performance of the two subtypes of AD/HD on the CAS and NEPSY. In addition, this study examined the performance of the two AD/HD groups on the Screening Test for Auditory Processing Disorders (SCAN). Since AD/HD children tend to have difficulty with language, the SCAN was used to determine if any of the AD/HD subjects had auditory processing difficulties that might impact their performance on the CAS and/or NEPSY subtests. The sample consisted of 118 children between the ages of 8 and 12 years of age. Using the DSM-IV criteria, the children were diagnosed as having three types of AD/HD: A Predominantly Hyperactive-Impulsive Type (AD/HD-HI), a Predominantly Inattentive Type (AD/HD-I) and a Combined Type The subtypes were also identified by the Attention Deficit Disorders Evaluation Scale-Home Version (ADDES-H). Only two subtypes, AD/HD-I and AD/HD-C, were identified by the ADDES-H. There were not enough AD/HD-HI subjects to include in the study. Therefore, this study focused on the AD/HD-I and AD/HD-C subtypes. A binomial logistic regression analysis was conducted on the AD/HD-I and AD/HD-C subtypes with selected subtests of the NEPSY and the four PASS Scales of the CAS. Results indicated a significant difference between the AD/HD-I and AD/HD-C groups on the Tower subtest of the NEPSY and the Planning Scale of the CAS. The Tower and the Planning Scale are both purported measures of executive functioning; however, results of the Planning Scale were in an unexpected direction. No significant difference was found between the two AD/HD groups on the ...

Identifying At-Risk Students: An Assessment Instrument for Distributed Learning Courses in Higher Education

Description: The current period of rapid technological change, particularly in the area of mediated communication, has combined with new philosophies of education and market forces to bring upheaval to the realm of higher education. Technical capabilities exceed our knowledge of whether expenditures on hardware and software lead to corresponding gains in student learning. Educators do not yet possess sophisticated assessments of what we may be gaining or losing as we widen the scope of distributed learning. The purpose of this study was not to draw sweeping conclusions with respect to the costs or benefits of technology in education. The researcher focused on a single issue involved in educational quality: assessing the ability of a student to complete a course. Previous research in this area indicates that attrition rates are often higher in distributed learning environments. Educators and students may benefit from a reliable instrument to identify those students who may encounter difficulty in these learning situations. This study is aligned with research focused on the individual engaged in seeking information, assisted or hindered by the capabilities of the computer information systems that create and provide access to information. Specifically, the study focused on the indicators of completion for students enrolled in video conferencing and Web-based courses. In the final version, the Distributed Learning Survey encompassed thirteen indicators of completion. The results of this study of 396 students indicated that the Distributed Learning Survey represented a reliable and valid instrument for identifying at-risk students in video conferencing and Web-based courses where the student population is similar to the study participants. Educational level, GPA, credit hours taken in the semester, study environment, motivation, computer confidence, and the number of previous distributed learning courses accounted for most of the predictive power in the discriminant function based on student scores from the survey.

Identifying Breast Cancer Disparities in the African-American Community Using a Mixed Methods Approach

Description: Utilizing a mixed methods approach in assessing cities and metropolitan areas with the highest rates of breast cancer disparities in African-American communities, this study presents the Affiliate perspective of the Susan G. Komen non-profit organization in combination with available socioeconomic data and academic literature. Analyzed through an anthropological lens, qualitative and quantitative data illuminate the lived experiences and dynamic circumstances in which breast cancer disparities are disproportionately experienced in 21 of the nation’s populations of African-Americans. Two main recommendations arose from this research: prioritization of granting to activities such as patient navigation, usage of patient narrative messaging, community-based participatory research methods of program development and implementation, mobile mammography delivery, usage of lay health educators, and self-advocacy education to alleviate barriers to healthcare and supplementation of the current educational activities of the Komen Affiliates through program sharing and leverage of current assets with consideration of current Affiliate capacity. These recommendations may help in alleviating breast cancer disparities present in African-American communities with the highest levels of disparities in the nation.

Identifying Changes in Resilience during Rehabilitation from a Spinal Cord Injury

Description: The study purposes were to identify changes in resilience, satisfaction with life (SWL), depression, spirituality, and functional independence (FI) and to examine the relationship between these variables, during the inpatient rehabilitation for a spinal cord injury (SCI). The sample included 42 individuals with a SCI, 33 males and 9 females, who were inpatients with a mean stay of 52 days (SD = 15.78). A repeated measures design was employed with questionnaires completed at three times during rehabilitation. Results indicated that there were significant changes in depression, satisfaction with life, spirituality, and FI during inpatient rehabilitation. Findings also indicated significant correlations between resilience, SWL, spirituality, and depression. Future studies developing interventions, and examining factors that predict resilience could help build resilience and may improve rehabilitation outcomes.
