Stability constants important to the understanding of plutonium in environmental waters, hydroxy and carbonate complexation of PuO{sub 2}{sup +}

Description: The formation constants for the reactions PuO{sub 2}{sup +} + H{sub 2}O = PuO{sub 2}(OH) + H{sup +} and PuO{sub 2}{sup +} + CO{sub 3}{sup 2} = PuO{sub 2}(CO{sub 3}){sup {minus}} were determined in aqueous sodium perchlorate solutions by laser-induced photoacoustic spectroscopy. The molar absorptivity of the PuO{sub 2}{sup +} band at 569 nm decreased with increasing hydroxide concentration. Similarly, spectral changes occurred between 540 and 580 nm as the carbonate concentration was increased. The absorption data were analyzed by the non-linear least-squares program SQUAD to yield complexation constants. Using the specific ion interaction theory, both complexation constants were extrapolated to zero ionic strength. These thermodynamic complexation constants were combined with the oxidation-reduction potentials of Pu to obtain Eh versus pH diagrams. 120 refs., 35 figs., 12 tabs.

A three-dimensional transient neutronics routine for the TRAC-PF1 reactor thermal hydraulic computer code

Description: No present light water reactor accident analysis code employs both high state of the art neutronics and thermal-hydraulics computational algorithms. Adding a modern three-dimensional neutron kinetics model to the present TRAC-PFI/MOD2 code would create a fully up to date pressurized water reactor accident evaluation code. After reviewing several options, it was decided that the Nodal Expansion Method would best provide the basis for this multidimensional transient neutronic analysis capability. Steady-state and transient versions of the Nodal Expansion Method were coded in both three-dimensional Cartesian and cylindrical geometries. In stand-alone form this method of solving the few group neutron diffusion equations was shown to yield efficient and accurate results for a variety of steady-state and transient benchmark problems. The Nodal Expansion Method was then incorporated into TRAC-PFl/MOD2. The combined NEM/TRAC code results agreed well with the EPRI-ARROTTA core-only transient analysis code when modelling a severe PWR control rod ejection accident.

Attitudes of Faculty Members Toward the Integration of Faith and Discipline at Selected Southern Baptist Colleges and Universities

Description: The attitudes toward the integration of faith and discipline of full-time faculty members at five selected Southern Baptist colleges and universities which are members of the Christian College Coalition were explored for this study. The integration of faith and discipline is a concept unique to Southern Baptist higher education. Arthur Walker, Jr., of the Education Commission of the Southern Baptist Convention defines the concept as referring to the mission of the institution, the personal faith of faculty members, and the professional involvement and interaction of faculty members with their students, regardless of disciplines. Since little information exists on faculty attitudes toward this concept, data were collected through a survey instrument on three dimensions of integration: professorial integration in the classroom, professorial integration in and out of the classroom, and institutional integration of faith and discipline.

The Use of Learning Styles in Teaching Social Studies in 7th and 8th Grade: A Case Study

Description: This qualitative case study examined the extent to which learning styles were used by teachers in four seventh and eighth grade social studies classrooms in a large suburban north Texas junior high school. The conclusions were as follows: 1) The environment on the junior high level did not afford the flexibility found in the elementary classroom. The changing of students, teachers, and the multi-purpose use of rooms did not afford flexibility of light, temperature, sound, and design preference. 2) The physical and the psychological categories had elements within each category that overlapped. A right brain activity closely aligned to a tactile/kinesthetic activity. A parallel between physical-mobility and psychological-global was noted, as well as a pattern between the global and the tactile/kinesthetic projects. 3) The split lunch period created problems for the global, kinesthetic, impulsive students. The academic environment was interrupted for a thirty minute period; students had to re-acclimate to a more analytic environment after lunch. 4) Each teacher alternated between primary style and secondary and tertiary styles. This mediation ability enabled each teacher to use all styles in lessons the researcher observed. 5) Abstract random and concrete random teachers did more group and team teaching than concrete sequential and abstract sequential teachers. Further, dominant sequential ordering in a teacher limited random activities. Whereas, dominant random ordering in a teacher limited sequential ordering activities. Both groups of teachers experienced teacher burnout when forced out of their primary style. 6) It was easier for those teachers whose primary and secondary ordering were opposite (CS/CR or AS/AR), as opposed to those whose primary and secondary ordering were the same (CS/AS or CR/AR), to align to a different environment. 7) These results suggest that teachers should not be required to stay in any one style. The flexibility of being able to alternate between ...

A Comparative Study of Terrorism in Southwest Asia 1968-1982

Description: This study assumes that political terrorism results from conscious decision-making by groups opposing a governing system, policy or process. The kinds of terrorist activity employed depend upon such factors as the philosophy, goals, objectives, and needs of the terrorist group. This presents a comparative analysis of three types of terrorists in southwest Asia: Palestinians, Marxist-Leninists, and Muslims. The first section summarizes and compares the three groups' motivational causes, philosophies, histories and sources of inspiration. The second section compares their behavior from four perspectives: trends and patterns, level of violence, tactical preferences, and lethality. The third section identifies and categorizes socioeconomic, political and military variables associated with tactic selection and acts of terrorism.

A Comparison of Adult Children of Alcoholic Families with Adult Children From Non-Alcoholic Families on Depression, Self-Esteem, and Anxiety

Description: The problem of this study was to test the differences between adult children from alcoholic families with adult children from non-alcoholic families on levels of depression, self-esteem, and anxiety. The sample consisted of 203 volunteers, all from the Counselor Education Department, 150 females and 53 males, ages 19 and older. Volunteers who were noted as being adult children of alcoholic families numbered 60. Measures used were the Children of Alcoholics Screening Test (CAST), the Beck Depression Inventory (BDI), the State-Trait Anxiety Inventory (STAI), and the Coopersmith Adult Self-Esteem Inventory (SEI). Multivariate Analysis of Variance was used to test for differences between groups. In addition, a secondary analysis using a one-way MANOVA was used to test for differences between dysfunctional and functional family of origin status on the dependent variables of depression, self-esteem, and anxiety.

Studies of Solvent Displacement from Solvated Metal Carbonyl Complexes of Chromium, Molybdenum, and Tungsten

Description: Flash photolysis techniques were applied to studies of solvent displacement by Lewis bases (L) from solvated metal carbonyl complexes of Cr, Mo, and W. On the basis of extensive studies of the reaction rate laws, activation parameters , and linear-free-energy-relationships, it was concluded that the mechanisms of solvent displacement reactions depend on the electronic and steric properties of the solvents and L, as well as the identities of the metal atoms. The strengths of solvent-metal bonding interactions, varying from ca. 7 to 16 kcal/mol, and the bonding "modes" of solvents to metals are sensitive to the structures of the solvent molecules and the identities of the metal centers. The results indicate dissociative desolvation pathways for many arene solvents in (solvent)Cr(CO)_5 (solvent = benzene, fluorobenzene, toluene, etc.) complexes, and are consistent with competitive interchange and dissociative pathways for (n-heptane)M(CO)_5. Different types of (arene)-Cr(CO)_5 interactions were suggested for chlorobenzene (CB) vs. fluorobenzene and other non-halogenated arenes, i.e. via σ-halogen-Cr bond formation in the CB solvate vs. π-arene-Cr bond formation through "isolated" double bonds in solvates of the other arenes. The data also indicate the increasing importance of interchange pathways for solvent displacement from the solvates of Mo and W vs. that of Cr.

Individual Resources, Social Environment, and Flood Victimization

Description: The study is a contextual analysis of flood victimization. Victimization is defined as the social, psychological, and physiological aftermath experienced by victims of a disaster. Disaster researchers concentrate on the victims' characteristics to explain the varying degrees of their victimization, providing only ambiguous results. Theorists such as Kreps, Wildavsky, and Douglas contend that the outcomes of disasters are contingent upon social structure. This analysis treats victimization as one such outcome. The condition and behavior of individuals can be explained by the presence of disaster and the conditions of social organization. A model explains victimization based on individual's attributes (individual resources), his social environment, and the disaster characteristics. This study uses the 1984 Mingo Creek Flood Victims Survey data to test the model. The data contain information measuring victimization. The survey data are linked with 1980 Census tract data. The tract data provide indicators of the social networks. This tract information, the contextual variables, taps the social conditions, including poverty, unemployment, geographic mobility, and family patterns. This study uses factor analysis to identify the dimensions of victimization. Regression tests the relationship between the contextual variables, the individual resource variables, the disaster characteristic variables, and victimization. The results of the analysis show that victimization is multidimensional with different types of variables being significant predictors for each dimension of victimization, one variable indicating the intensity of the disaster, the dollar value of damage victims experienced, is found to be a significant predictor of the psychological, physiological, and social disruption aspects of victimization. Variables measuring the family and unemployment patterns in the victims' census tract are significant predictors of the psychological and social disruption aspect of victimization. The findings provide general support for the proposed model of victimization. However, victimization is multidimensional with each dimension having a unique set of predictors. Based on the ...

Anger Reduction in Closed Head Injured Individuals with Group Social Skills Training

Description: In the present study, an anger management treatment program was compared to a pseudo-social skills training program (self-help group) and waiting list control group to determine its effectiveness in reducing irritable/angry behavior in head injured subjects. Subjects consisted of 28 adults with previous head injury trauma who had difficulty with excessive irritability and anger. Subjects averaged 35.4 years of age and had an average of 8.9 years post head injury. Treatment consisted of 10 group sessions over a five week period. Anger management training was designed to teach subjects self management skills aimed at reducing the frequency of angry acting out behavior. Training methods included role playing, relaxation training, assertiveness training and cognitive restructuring. The pseudo-social skills training group was a self-help group designed to encourage discussion of irritability problems without teaching specific coping techniques. To assure some degree of homogeneity in cognitive abilities among subjects, minimum eligibility scores were required on five subtests of the Wechsler Adult Intelligence Scale - Revised and the Peabody Picture Vocabulary Test. Dependent measures were pre and posttreatment scores obtained from five categories of the Katz Adjustment Scale - Relative form: belligerence, negativity, general psychopathology, social obstreperousness, and social role functioning. In addition, pre and posttreatment recordings of observed angry/irritable behavior in the subjects were obtained from a significant other. Results failed to reveal statistically significant differences on the dependent measures between the three study groups. In addition, analysis failed to reveal any significant variables that predicted outcome. It is evident that much more organized research is needed to further investigate the possibilities of treatment for various problems encountered by those with head injuries.

A Study Concerning the Use of Microcomputers for Word Processing in College Freshman Composition at a Community College

Description: The purpose of this study was to determine the effect of using word processing and proofreading software in freshman composition at a community college. This study used pretest and posttest measures to determine if significant differences in the improvement of composition skills occurred between students in a composition class that did not use microcomputers and students in a composition class that did use microcomputers. Objective tests and writing samples were used as measurements. The population for the study consisted of students enrolled in freshman composition classes at a two year community college. Students self-selected enrollment in each class. Three hundred students who completed the pretest and posttest measures and completed the course were included in the study. There was no significant difference found in the improvement of writing skills between the two groups as measured by the objective test or the writing samples. There was a significant difference found in the withdrawal rate of students from the classes. The computer class had a significantly higher withdrawal rate than the non-computer class.

Regulation of Colony-Stimulating Factor-1 Biosynthesis

Description: Recent studies suggest that synthesis of the Colony-stimulating factor (CSF) is a well regulated process. However, the molecular mechanisms of the signal transduction of the various inducers of CSF such as monokines and lymphokines are not well understood. Using Interleukin 1 (IL-1) stimulation of CSF-1 in the MIA PaCa-2 cell line as a model system, the involvement of G-protein has been studied. The IL-1 induction of CSF-1 synthesis can be inhibited by both Pertussis toxin and Cholera toxin, which are known to modify the Gᵢ and Gₛ proteins respectively, thus activating adenylate cyclase to release more cAMP. The toxin inactivation can be prevented by inhibitors of the ADP-ribosylation such as, benzamide and MBAMG. Addition of dibutyryl-cAMP inhibits the IL-1 induced CSF production. Both Theophylline and Forskolin which increase cAMP by inhibiting phosphodiesterase and stimulating adenylate cyclase respectively, also inhibit CSF-1 production. Results from these studies have shown that cAMP level inversely regulates the biosynthesis of CSF-1. Preincubation of MIA PaCa-2 cells with IL-1 and 5'- guanylylimidodiphosphate (GppNHp) prevents the inhibitory effect of pertussis toxin on CSF-1 production. These data are consistent with the hypothesis that IL-1 binds to its receptor and couples to Gᵢ∝ resulting in the inhibition of adenylate cyclase and reducing cAMP level. Lowering of the' cAMP level leads to the activation of CSF-1 gene expression. The activity of another inducer of CSF-1 production in this system, 12-0-tetradecanoylphorbol-13-acetate (TPA), can be abolished by 1- (5-isoquinolinesulfonyl)-2-methylpiperazine dihydrochloride (H-7), which is a specific inhibitor of protein kinase C. However, H-7 failed to inhibit IL-1 stimulated CSF-1 production. Other known activators of protein kinase C namely, Ca²⁺ and L-α-l-oleoyl-2-acetoyl-sn- 3-glycerol (OAG), also increase CSF production. On the other hand, Indomethacin which is known to inhibit prostaglandin E (PGE), stimulates CSF-1 production in MIA PaCa-2 cells. These data suggest that different mechanisms ...

Development of Cooperative Education at the University of North Texas, 1976-1988

Description: The main purpose of the study is to describe the developmental story of one of the larger university cooperative education programs in the United States to provide the evidence of outcomes and to utilize selected elements of the program in other colleges and universities. The study utilizes historical methodology with a descriptive approach to investigate and analyze the program's establishment, its development of staffing, organization, students, employers, funding, and its evaluation by using primary and secondary sources, annual reports, federal grant request proposals, evaluation reports, and the on-campus newspaper. The information for this study was also gathered through personal interviews with previous and present staff members of the program. The study shows that the program was established in the dean of students' office, but in order to get more support from the faculty, the program was moved to the academic affairs office. As a result of the academic support by the faculty, the program expanded. The findings show that the federal grant, Title VIII, contributed significantly to the initiation and growth of the program. The investigator observes that the director's leadership and the staff members' commitment to the program were two of the most important factors in the continued growth of the program. Strong commitment by the chief executive officer of the institution has also been a strong factor in the continuous growth of the program. The study indicates that close affiliation with professional organizations has benefited the program by influencing the development of quality and effective, diverse employers. The results show that the cooperative program significantly aided the students, institutions, and employers annually by placing approximately 1,200 students in their major-related working places.

Criteria by Which Ad Hoc Labor Arbitrators are Selected by Union and Management Advocates in the Petroleum Refining Industry

Description: A non-experimental, descriptive study was conducted to examine the criteria by which ad hoc labor arbitrators are selected in the petroleum refining industry. Three factors — arbitrator background, recognition, and arbitration practice — were examined to determine their relative importance to advocates selecting ad hoc labor arbitrators. The population of the study consisted of management and labor union advocates in the petroleum refining industry who routinely select ad hoc labor arbitrators. Participating management and union advocates completed a questionnaire used to gather respondents' evaluations of criteria considered in the selection of ad hoc arbitrators. Responses to statements designed for measuring relative importance of the criteria considered were recorded. Descriptive statistics, discriminant analysis, and tests of significance were used in the treatment of the data.

Faculty and Administrators' Job Preferential and Job Satisfaction Factors at the University of Guam

Description: Research into job preference and job satisfaction addresses the agreement between individual and institutional values leading to job choice and job satisfaction. This research assessed ten job preference and ten job satisfaction factors at the University of Guam. Ninety-one faculty members and 32 administrators completed a two-page paired-comparison questionnaire. Demographic data were also collected. Factors' hierarchy and valence positions were reported and subjected to "PCSTATS" program to determine significance among pairs. Significant differences existed in three of the four hypotheses measuring the job preferential factors: advancement, benefits, company, co-workers, hours, pay, security, supervisor, type of work, and working conditions; and job satisfaction factors: good wages, job security, interesting work, tactful disciplining, in on things, working conditions, management loyalty, appreciation, promotion, and sympathetic understanding. Additional findings were made using post hoc analysis. Results indicated that administrators perceived others' preferences to be (a) pay, (b) advancement, and (c) type of work while faculty chose (a) type of work, (b) pay, and (c) advancement. In job satisfaction administrators selected (a) promotion, (b) good wages, and (c) job security, while the faculty chose (a) interesting work, (b) good wages, and (c) promotion. Self job preference factors chosen by males and females were (a) type of work and (b) pay with (c) advancement and (c) co-workers, respectively. The top three self job satisfaction factors chosen by males and females were (a) interesting work, (b) good wages, and (c) promotion. Disagreement is evident between groups. It is recommended that the findings be used in the selection and retention of faculty members at the University of Guam.

Anomalous Behavior in the Rotational Spectra of the v₈=2 and the v₈=3 Vibrations for the ¹³C and ¹⁵N Tagged Isotopes of the CH₃CN Molecule in the Frequency Range 17-95 GHz

Description: The rotational microwave spectra of the three isotopes (^13CH_3^12C^15N, ^12CH_3^13C^15N, and ^13CH_3^13C^15N) of the methyl cyanide molecule in the v_8=3, v_8=2, v_7=1 and v_4=1 vibrational energy levels for the rotational components 1£J£5 (for a range of frequency 17-95 GHz.) were experimentally and theoretically examined. Rotational components in each vibration were measured to determine the mutual interactions in each vibration between any of the vibrational levels investigated. The method of isotopic substitution was employed for internal tuning of each vibrational level by single and double substitution of ^13C in the two sites of the molecule. It was found that relative frequencies within each vibration with respect to another vibration were shifted in a systematic way. The results given in this work were interpreted on the basis of these energy shifts. Large departure between experimentally measured and theoretically predicted frequency for the quantum sets (J, K=±l, ϑ=±1), Kϑ-l in the v_8=3 vibrational states for the ^13c and ^15N tagged isotopes of CH_3CN showed anomalous behavior which was explained as being due to Fermi resonance. Accidently strong resonances (ASR) were introduced to account for some departures which were not explained by Fermi resonance.

The Use of Part-Time Faculty in Associate Degree Nursing, Social Science, and Biological Science Programs

Description: This study surveyed the opinions of academic administrators of associate degree nursing programs, community college social science programs, and community college biological science programs regarding major benefits and concerns associated with the employment of part-time faculty. This study found that most part-time social science faculty teach in the classroom, half participate in non-teaching faculty activities, and most are paid a contract amount per course or credit hour. Part-time biological science faculty differed only in that most teach a combination of classroom and lab/practicum. Part-time nursing faculty differed in all three areas. Most part-time nursing faculty teach in lab or practicum settings, most participate in more non-teaching activities than other part-time faculty, and most are paid an hourly wage. However, the benefits and concerns associated with the employment of part-time nursing faculty were not significantly different from those identified by academic administrators of the other programs with one exception. Academic administrators felt that part-time nursing faculty expose students to the latest technologies in specialty areas and part-time social science faculty do not. The benefits cited by the respondents, that were in addition to the benefits most frequently cited in the literature, include increased interaction with the community and the ability to "try out" prospective full-time faculty. The concerns cited by respondents, that were in addition to the concerns most frequently cited in the literature, include the inability to find qualified part-time faculty to fill available positions and the concern that the employment of part-time faculty causes resentment among full-time faculty. The results from this study indicate that the literature pertaining to the benefits and concerns associated with the employment of social science and biological science part-time faculty in community colleges can be used to develop policies regarding part-time faculty in associate degree nursing programs.
