Beethoven's Transcendence of the Additive Tendency in Opus 34, Opus 35, Werk ohne Opuszahl 80, and Opus 120

Description: The internal unity of the themes in a sonata-allegro movement and the external unity of the movements in a sonata cycle are crucial elements of Beethoven's compositional aesthetic. Numerous theorists have explored these aspects in Beethoven's sonatas, symphonies, quartets, and concertos. Similar research into the independent variation sets for piano, excluding Opus 120, has been largely neglected as the result of three misconceptions: that the variation sets, many of which were based on popular melodies of Beethoven's time, are not as worthy of study as his other works; that the type of hidden internal relationships which pervade the sonata cycle are not relevant to the variation set since all variations are, by definition, related to the theme; and that variations were composed "additively," that is, one after another, without any particular regard for their order or relationship to one another. The purpose of this study is to refute all three of these incorrect assumptions. Beethoven was concerned with the order of variations and their relationship to one another, and he was able to transcend the additive tendency in a number of ways. Some of his methods included registral connection, registral expansion, rhythmic acceleration, textural expansion, dynamics, articulation, and motivic similarities. Chapter I contains a discussion of the role of the variation set in Beethoven's overall output. The teachers, composers, and works which may have influenced him are also discussed as well as his training in variation composition. Finally, those factors which Beethoven employed to unify his sets are listed and explained. Chapters II-V are devoted to detailed analyses of four striking variation sets: Opus 34, Opus 35, WoO 80, and Opus 120. Chapter VI presents a summary of the findings. It suggests that each of the sets investigated has a unique form and that each variation has a distinct place ...

Validation of a Coupled Herbicide Fate and Target Plant Species Effects Model

Description: A series of experiments provided data to parameterize and validate a coupled herbicide fate and target plant species effects model. This simulation model is currently designed to predict responses of water hyacinth populations to treatments of the dimethylamine formulation of 2,4- dichloro-phenoxy acetic acid (2,4-D -DMA). Experiments investigated 1) the response of water hyacinth to varying exposures of 2,4-D (DMA); 2) the role of water hyacinth density and herbicide interception in treatment effectiveness using 2,4-D (DMA); and 3) the importance of root exposure to obtain control of water hyacinth using 2,4- D (DMA). Results demonstrated the importance of leaf or canopy interception of 2,4-D (DMA) sprays in obtaining control of water hyacinth populations. The critical threshold plant tissue concentration of 2,4-D (DMA) required to elicit maximum mortality (98%) was estimated to be approximately 12 mg 2,4-D per kg water hyacinth tissue (wet weight). Root uptake apparently plays little or no role in the effectiveness of this herbicide for controlling water hyacinth growth. Validation trials illustrated the efficacy of the current model. The model was validated with data from a field operation. This research has provided considerable insight into optimal use of this auxin-type herbicide for control of water hyacinth, a monocotyledon.

Toxicological Characterization of Trinity River Sediments

Description: Sediments in the Trinity River were chemically, physically and biologically characterized and assessed for toxicity. Laboratory bioassays were conducted to identify sediments which induced toxic responses in test organisms and to document these responses through time. Metal and organic contaminant concentrations in bottom sediments were measured. Relationships between these concentrations and biological responses observed in laboratory bioassays were determined. Toxicity identification / reduction methods were used to characterize sediment toxicants. Sediment oxygen demand was also measured in resuspended and undisturbed bottom sediments through time. The Background Sediment Chemistry Approach and the Sediment Bioassay Approach were used to assess sediment quality. Sediment toxicity was observed in whole sediment bioassays using Chironomus tentans as the test species. A relationship between sediment contaminant concentration and toxicity was observed in approximately sixty percent of the sediments. Oxygen demand of resuspended sediments was elevated in sediments at two locations on the river. Oxygen demand of undisturbed sediments was elevated at one location on the river. Characterization of sediment toxicants was conducted using EDTA, pH, and carbon treatments and manipulations of the sediments. Aeration tests were also used to evaluate the contribution of volatile organic contaminants to observed toxicity.

Trends in Strategic Planning in Private Social Service Agencies: A Test of the Ramanujam and Venkatraman Planning Model

Description: This study modified the Ramanujam and Venkatraman (1987) questionnaire that was used to develop their model of planning system dimensions and planning effectiveness, and tested the model on a sample of private social service agencies. The criterion measures were level of planning sophistication, agency size, perceived environmental uncertainty, and relative competitive position. The sample was randomly drawn from private social service agencies which were members of the Community Council of Greater Dallas. Telephone interviews with fifty executive directors were conducted by a trained, impartial interviewer. Stepwise discriminant analysis was used to predict group membership between informal and formal planners. Of the nine dimensions in the model, three dimensions correctly classified 84 percent of the sample. The three dimensions were fulfillment of planning objectives, use of decision making techniques, and lack of resistance to planning. The level of perceived environmental uncertainty was another criterion set. Directors who perceived high uncertainty paid more attention to the external environment, used more decision making techniques, and relied on functional specialists when planning. Large and small agencies were classified by their annual budgets. Stepwise discriminant analysis using the planning system dimensions failed to reject the null hypothesis. Agencies reporting strong relative competitive positions placed greater emphasis on seeking information for planning from external sources. These agencies also reported less resistance for planning within their organizations, fulfillment of more planning objectives, and a flexible planning system. The discriminant analysis correctly classifed 74 percent of the sample. Finally, the study provided some baseline information on the use of planning techniques by private social service agencies. Just over half of the sample reported having written strategic plans covering at least three years.

Teacher Evaluation Processes and Professional Development Programs in Independent Schools

Description: The purposes of this study were to determine (a) what teacher evaluation processes or instruments are used in the 45 independent schools of the Southwest, (b) what types of professional development activities or programs are provided for teachers in these schools, and (c) how the development and implementation of the teacher evaluation process and professional development programs are perceived by the teaching faculty in selected schools. Questionnaires were administered to chief administrators of the 45 member schools of the Independent Schools Association of the Southwest. From the 28 schools submitting completed questionnaires and evaluation instruments, it was found that: (a) 3 of the schools had a very informal process, (b) 7 of the schools had an informal process, (c) 12 of the schools had a formal process, and (d) 6 of the schools had a very formal process. Four generalizations emerged from factors evident at the 5 schools selected for on-site visitations which should be addressed by independent schools regardless of the type of evaluation process used: (a) each school should develop a teacher evaluation policy; (b) each school should develop evaluation criteria and procedures that relate to each teacher's classification; (c) each school should delineate the specific role of the chief administrator in the evaluation process, and (d) each school should design a program of preferred professional development activities for each teacher's classification and level of the school. Finally, the recommendation was made that further research on teacher evaluation in independent schools include the investigation of how and why schools select a particular teacher evaluation process.

Hausdorff, Packing and Capacity Dimensions

Description: In this thesis, Hausdorff, packing and capacity dimensions are studied by evaluating sets in the Euclidean space R^. Also the lower entropy dimension is calculated for some Cantor sets. By incorporating technics of Munroe and of Saint Raymond and Tricot, outer measures are created. A Vitali covering theorem for packings is proved. Methods (by Taylor and Tricot, Kahane and Salem, and Schweiger) for determining the Hausdorff and capacity dimensions of sets using probability measures are discussed and extended. The packing pre-measure and measure are shown to be scaled after an affine transformation. A Cantor set constructed by L.D. Pitt is shown to be dimensionless using methods developed in this thesis. A Cantor set is constructed for which all four dimensions are different. Graph directed constructions (compositions of similitudes follow a path in a directed graph) used by Mauldin and Willjams are presented. Mauldin and Williams calculate the Hausdorff dimension, or, of the object of a graph directed construction and show that if the graph is strongly connected, then the a—Hausdorff measure is positive and finite. Similar results will be shown for the packing dimension and the packing measure. When the graph is strongly connected, there is a constant so that the constant times the Hausdorff measure is greater than or equal to the packing measure when a subset of the realization is evaluated. Self—affine Sierpinski carpets, which have been analyzed by McMullen with respect to their Hausdorff dimension and capacity dimension, are analyzed with respect to their packing dimension. Conditions under which the Hausdorff measure of the construction object is positive and finite are given.

The Beginnings of Music in the Boston Public Schools: Decisions of the Boston School Committee in 1837 and 1845 in Light of Religious and Moral Concerns of the Time

Description: The research problems of this dissertation were: 1) A description of the perceived value of music in light of political undercurrents in Boston prior to and during the years under investigation, and 2) the profile of the constituency of the Boston School Committee and Committee on Music in 1837 and 1845. Questions addressed the effect of religious and moral concerns of the day on the decision by the School Committee in 1837 to try music in the curriculum, and the possible effect of religious politics on Lowell Mason's dismissal from the schools in 1845. In the minds of mid-nineteenth century Bostonians, religious and moral values were intrinsic to the very nature of music. Key members on the School Committee portrayed music as being spiritual yet nonsectarian in its influence. Therefore, the findings suggest that music was believed to provide common ground between opposing and diverse religious sects. Reasons given for Mason's dismissal by John Sargent, a member of the Committee on Music, showed parallels to H. W. Day's accusations in the press a year earlier that Mason had managed his position in a sectarian manner. Sargent's background supports the theory that religious politics were at work in Mason's dismissal. Although members of the School Committee of 1845 were religious, only isolated cases support the proposition that any of them would have opposed Mason strictly on the basis of religious issues. Evidence suggests that their passivity to the action by the Committee on Music was probably due to concurrent public criticism of attempts at school reform within the Committee. While under such scrutiny, Committee members' inaction regarding Mason's dismissal may have reflected a desire not to jeopardize their own positions as a political body.

Harmony in the Songs of Hugo Wolf

Description: The songs of Hugo Wolf represent the culmination of the Romantic German Lied tradition. Wolf developed a personal chromatic harmonic style that allowed him to respond to every nuance of a poetic text, thereby stretching tonality to its limits. He was convinced, however, that despite its novel nature his music could be explained through the traditional theory of harmony. This study determines the degree to which Wolf's belief is true, and begins with an evaluation of the current state of research into Wolf's harmonic practice. An explanation of my analytical method and its underlying philosophy follows; historical perspective is provided by tracing the development of three major elements of traditional theory from their inception to the present day: fundamental bass, fundamental chords, and tonal function. The analytical method is then applied to the works of Wolf's predecessors in order to allow comparison with Wolf. In the investigation of Wolf's harmonic practice the individual elements of traditional functional tonality are examined, focusing on Wolf's use of traditional harmonic functions in both traditional and innovative ways. This is followed by an investigation of the manner in which Wolf assembles these traditional elements into larger harmonic units. Tonal instability, rapid key shifts, progressive tonality, tonal ambiguity, and transient keys are hallmarks of his style. He frequently alters the quality of chords while retaining the function of their scale-degree root. Such "color" chords are classified, and their effect on harmonic progression examined. Wolf's repetitive motivic style and the devices that he employs to provide motion in his music are also discussed. I conclude by examining Wolf's most adventuresome techniques—including parallel chords successions, chromatic harmonic and melodic sequences, and successions of augmented triads--and the suspension of tonality that they produce. This project encompasses all of Wolf's songs, and should be a useful tool for Wolf ...

An Exploratory Investigation of Socio-Economic Phenomena that May Influence Accounting Differences in Three Diverse Countries

Description: This dissertation attempts to provide an exploratory structure to respond to, and tries to resolve, an existing void in international accounting research. The void is a lack of coherently structured, nation-specific, descriptive research to investigate socio-economic phenomena which may influence financial accounting. This dissertation's salient features include a political economy theory, an exploratory, sociological method, and a case study format. The political economy of accounting, introduced by Tinker [1980] and refined by Cooper and Sherer [1984], emphasizes a persuasive social relations dimension. This theory motivates selection of three countries (the United States, France, and Japan) that appear to have divergent socio-cultural environments. An exploratory and analytical approach of modified (enlarged) exogenism, developed by Smith [1973, 1976] and adapted to accounting by McKinnon [1986], provides an analytic structure for this exploratory investigation. Modified exogenism focuses upon an open, dynamic social system (the process of financial accounting), and provides analysis reflecting four major areas (the environment, intrusive events, intra-system activity, and trans-system activity). After examining the nation-specific financial accounting (socio-economic) structures for each country, an analysis of selected financial disclosures attempts to gain a better understanding of how socio-economic factors have influenced the development of financial accounting. My primary objective is to attempt to provide some insight about ,how diverse socio-political factors have impacted the development of financial accounting in three countries. Library research of nation-specific literature attempts to extract a relatively accurate picture of social, political, and economic institutions and policies, and relates such findings to financial accounting processes for each nation. This dissertation attempts to provide a necessary foundation for future theoretical international accounting harmonization studies.

The Effects of Voluntary Lateral Orienting on Positive Manifold for Lateralized Cognitive Tasks

Description: As an extension of previous studies (Urbanczyk, Angel, & Kennelly, 1988) examining the effects of unimanual finger tapping on lateralized cognitive tasks, lateral body orienting was added to an established dual task paradigm to generate differential hemispheric activation and shifts of attention. One hundred twenty university students retained sequences of digits or spatial locations for 20 seconds either alone or during finger tapping. By turning both head and eyes left or right, the hemisphere congruent with the sequences (LH for digits, RH for locations) or incongruent (vice versa) was activated. Activation had little effect on retention means but greatly affected resource composition supporting task performance. Congruent orientation produced significantly higher positive correlations between digit and location tasks than incongruent orientation. Females showed higher sequence retention correlations than males across both orienting groups. For females, congruent activation enhanced tapping rates and retention-tapping correlations. For males, activation affected neither of these. Discussed in light of neuroanatomical research, these results suggest that congruent attentional orienting may integrate regions of the less activated hemisphere into networks of the more activated hemisphere. This unification may occur more readily across the female corpus callosum, producing a greater dependence upon a general attentional resource than for males, who appear to depend more upon hemispheric resources.

Field Dependence of Optical Properties in Quantum Well Heterostructures Within the Wentzel, Kramers, and Brillouin Approximation

Description: This dissertation is a theoretical treatment of the electric field dependence of optical properties such as Quantum Confined Stark (QCS) shifts, Photoluminescence Quenching (PLQ), and Excitonic Mixing in quantum well heterostructures. The reduced spatial dimensionality in heterostructures greatly enhances these optical properties, more than in three dimensional semiconductors. Charge presence in the quantum well from doping causes the potential to bend and deviate from the ideal square well potential. A potential bending that varies as the square of distance measured from the heterostructure interfaces is derived self-consistently. This potential is used to solve the time-independent Schrodinger equation for bound state energies and wave functions within the framework of the Wentzel, Kramers, and Brillouin (WKB) approximation. The theoretical results obtained from the WKB approximation are limited to wide gap semiconductors with large split off bands such as gallium arsenide-gallium aluminum arsenide and indium gallium arsenide—indium phosphide. Quantum wells with finite confinement heights give rise to an energy dependent WKB phase. External electric and magnetic fields are incorporated into the theory for two different geometries. For electric fields applied perpendicular to the heterostructure multilayers, QCS shifts and PLQ are found to be in excellent agreement with the WKB calculations. Orthogonality between electrons and holes gives rise to interband mixing in the presence of an external electric field. On the contrary, intraband mixing between light and heavy holes is not sufficiently accounted for in the WKB approximation.

The Prediction of Homophobic Attitudes among College Students

Description: A review of the literature on homophobia indicates that negative attitudes toward homosexuals and homosexuality have been empirically related to numerous socio-demographic and attitudinal variables. Research to this date has focused on the relationship between individual variables and homophobia rather than examining multiple variables simultaneously. The purpose of the present investigation was to identify the factors which are predictive of homophobia. One hundred and ninety-four female and 115 male participants completed a biographical information questionnaire requesting socio-demographic information, self-proclaimed religiosity, frequency of church attendance, self-proclaimed political orientation, and political party identification. Participants also completed measures of attitudes toward male homosexuality, attitudes toward lesbianism, attitudes toward women, authoritarianism, sex anxiety, sexual attitudes, and socio-economic status. Statistical treatment of the data through principal components analysis indicated that homophobic attitudes are best predicted by a factor identified as "conservatism". Other factors were identified which predicted homophobia to a lesser extent. Male participant gender was determined to predict homophobia toward male homosexuals, but gender was not found to predict homophobic attitudes toward lesbians.

Ethical Reasoning Among Baccalaureate Female Nursing Students

Description: The focus for this study was ethical reasoning among baccalaureate female nursing students. This descriptive and correlational study examined the ethical reasoning of freshmen and senior students at a large southwestern university for women. The research instrument used was the Defining Issues Test developed by Rest. The senior nursing students differed significantly (p < ,05) from the freshmen nursing students in ethical reasoning. However, nursing majors did not differ significantly from the non-nursing majors. A multiple regression analysis was performed that identified two factors associated with ethical reasoning (viz., age and GPA), The correlation coefficients were r= .377 for age and P_ score and r= .315 for GPA and P score. Older students were found to be significantly more advanced in ethical reasoning than were younger students. Students with higher GPAs used principled reasoning significantly more often than did students with lower GPAs. Of interest are the findings related to demographic characteristics, ethnicity, and religious preference. The sample was predominantly white, but a significant difference in use of principled reasoning between whites and non-whites was found. In the sample, whites used ethical reasoning more often than did non-whites. The students in the sample who labeled themselves as Baptists were significantly different from Traditional Christians (Methodists, Episcopalians, Presbyterians, Lutherans, and members of the Church of Christ) and Other Christians (all others, excluding Baptists, Catholics, and the Traditional Christians). The Baptist group used principled reasoning less often than did the other two groups of Christians. The Catholics were not significantly different from the Baptist, Traditional Christian, or Other Christian groups. The results are ambiguous and may reflect only a conservative philosophy or a conservative theological ideology rather than cognitive processing.

The Effect of Sequencing Microeconomics and Macroeconomics on Learning

Description: The purpose of this study was to determine the effect on student learning from the sequence in which microeconomics and macroeconomics courses are taken. The sample for this study consisted of all students enrolled in 23 sections of Economics 1100 (Principles of Microeconomics) and 10 sections of Economics 1110 (Principles of Macroeconomics) during the fall semester, 1987, at the University of North Texas. The sample also consisted of all students enrolled in 14 sections of Economics 1100 and 12 sections of Economics 1110 during the spring semester, 1988, at the University of North Texas. The instruments chosen for use in measuring cognitive gains were two versions, each with 14 items, selected from the Joint council on Economic Educations's Revised Test of Understanding College Economics. Data were analyzed using hierarchical regression on five models. Each model used a different dependent variable to measure cognitive gain. The dependent variables were additive grade points, additive absolute improvement posttest scores, gap-closing posttest scores, microeconomic gap-closing scores and macroeconomic gap-closing posttest scores. The general hypothesis that students who complete microeconomics instruction followed by macroeconomics instruction have significantly higher cognitive gains than students who complete macroeconomics instruction followed by microeconomics instruction was not verified by the main effects. While the main effect of sequence was not significant, the interaction of sequence with previous high school economics was significant in the models using dependent variables of additive absolute improvement posttest score, gap-closing posttest score and microeconomic gap-closing posttest score. In addition, the interaction of sequence with previous college economics was significant on the dependent variable gap-closing posttest score. These findings seem to indicate that students who complete a sequence of macroeconomics followed by microeconomics with no previous exposure to economics have higher cognitive gains. In addition, students who complete a sequence of microeconomics followed by macroeconomics and ...

Admission Factors Related to Success in Doctoral Programs in Vocational-Technical Education in Texas and Oklahoma

Description: This study identified the admissions criteria for selected doctoral programs in vocational-technical education in Oklahoma and Texas and investigated the relationship of these criteria to success in the doctoral programs. Success in the doctoral programs was identified in terms of cumulative doctoral grade point average. Data were obtained through a questionnaire designed to ©licit both general information concerning admissions criteria for vocational-technical doctoral programs at the selected institutions and to collect specific information on a random sample of twenty doctoral candidates from each of the four selected institutions. Factors considered included birthdates, gender, scores on admissions tests, grade point average in the masters program, the year the latest masters was completed, number of colleges attended, and cumulative doctoral grade point average. A statistical analysis using nine separate one-way analyses of variance determined that four of the nine factors considered proved to be statistically significant at the .05 level or better when correlated with the criterion variable (cumulative doctoral grade point average). Those factors were gender, Graduate Record Examination verbal and composite scores, and masters grade point average. The results of the study basically parallel findings of research concerning admissions criteria and success in graduate programs in other areas. Additional research efforts should address the issue of determining the most appropriate decision logic model for making admissions decisions in programs at the graduate levels.

Kinetics Studies of Substituted Tungsten Carbonyl Complexes

Description: Thermal reactions and flash photolysis are used to study the olefin bond-migration promoted by tungsten carbonyls. Substitution of piperidine (pip) by 2- allylphenyldiphenylphosphine (adpp) in the cis-(pip)(η^1- adpp)W(CO)-4 complex was investigated, and no olefin bond-migration was observed. This suggests that a vacant coordinated site adjacent to the coordinated olefin is an essential requirement for olefin bond rearrangement. The rates of olefin attack on the photogenerated coordinatively unsaturated species, cis-[(CB)(η^1-ol- P)W(CO)-4] (CB = chlorobenzene, p-ol = Ph-2P(CH-2)-3CH=CH-2; n = 1-4) were measured. Kinetics data obtained both in pure CB and in CB/cyclohexane mixtures support a dissociative mechanism in which the W-CB bond is broken in the transition state. In contrast to results observed in studies of other related systems, no olefin bond-migration is noted. This observation is attributed to P-W coordination at all stages of the reaction, which precludes formation of a reactive intermediate containing a vacant coordination site adjacent to a P-ol bond.

Family Environment. Lifestyle, and Control Factors of Depressed Adolescents and Their Parents

Description: The problem of this study was to identify variables in the family environment that may describe depressed adolescents' families. This study was based on Adlerian theory. The Family Environment Scale (FES) was used to measure the family atmosphere. The Lifestyle Scale (LS) was used to examine the adolescent's unique system of beliefs, values, and attitudes. The Internal-External Locus of Control Scale (IE) was used to measure the extent of external control exhibited by the adolescents and their parents. The subjects of this study were 31 depressed adolescents from 2 suburban psychiatric hospitals and one of each of the adolescent's parents. The subjects were from a homogeneous socioeconomic population showing no significant variation in the demographic categories of sex, race, chronological birth order, or marital status of the parents. Scores were compared with normative data. Product moment correlations were calculated between the results of the subscales on the 3 instruments. A principal components factor analysis was performed to determine if any patterns existed.

Tribhuvan University and its Educational Activities in Nepal

Description: The purpose of this study was to discuss the role of Tribhuvan University in the development of higher education in Nepal by examining the university's historical development and educational activities. Despite negligence and opposition to public higher education by the rulers of Nepal before 1951, Nepalese higher education began with the establishment of Trichandra College in 1918. From 1951 until the establishment of Tribhuvan University in 1959, several public as well as private colleges were also established. The establishment of the university in 1959 marked the beginning of the government-controlled system of higher education in Nepal. As the first and only national institution of higher education, Tribhuvan University has played a significant role in developing a system of higher education in the country. During its first ten years, Tribhuvan University did not operate as a comprehensive institute of higher education. The Tribhuvan University Act of 1971, however, altered the structure, organization, and functions of the university and gave it additional roles and responsibilitites. By the mid-1980s, Tribhuvan University had increased its number of colleges from 49 (1970) to more than 128. Moreover, these colleges have expanded their programs and levels of education. This dissertation's six chapters describe the demographic, cultural, and historical setting of Nepal, the educational activities of Nepal before the establishment of Tribhuvan University, and the university's educational activities from its establishment in 1959 through the mid-1980s. The study shows that the university, in a 26-year period, had expanded it activities significantly and had proven its role as an important factor in the development of higher education in Nepal. The study also indicates that various governmental and non-governmental agencies have been actively involved in determining the educational activities of Tribhuvan University in Nepal.

Studies of Nitrogen-containing Compounds Having Pyrethroid-like Bioactivity

Description: During recent years most of the successful developments in pyrethroids have been primarily concerned with structural or compositional variations. As a part of our continuing interest in pyrethroid insecticides, nitrogen-containing compounds having pyrethroid-like structures were synthesized. Seven prolinate compounds, N-(substituted)-phenyl-prolinates and N-carbobenzoxy-prolinates were coupled with known pyrethroid alcohols. These structural variations which "locked in" a specific conformation between the nitrogen and chiral a-carbon in the acid moiety of fluvalinate were studied to determine the influence of certain conformations on insecticidal toxicity. The toxicity data for the prolinate compounds showed intermediate mortality against nonresistant cockroaches. It was concluded that the conformation imposed by the proline ring portion of the esters was probably close to the favored conformation for interaction of fluvalinate-like pyrethroids with the insect receptor site. A second series of nitrogen-containing compounds, twenty-five carbamate esters resulting from the condensation of N-isopropyl-(substituted)-anilines and N-alkyl-(substituted)-benzylamines with appropriate pyrethroid alcohols were studied for insecticidal activity. These studies were conducted on pyrethroid-susceptible houseflies. Some of the carbamate esters exhibited high toxicity when synergized by piperonyl butoxide. For example, the toxicity ( LD 50 ) of O-a-cyano-3-phenoxyfaenzyl-N-a,a-dimethyl-4-bromo-benzyl carbamate was 0.012 ug/g, which is significantly greater than that reported for the potent pyrethroid, fenvalerate. Correlations of insecticidal activity with respect to structure and conformational factors of the carbamate esters have been made. The N-isopropyl substituent decreases insecticidal activity in the N-benzyl-derived compounds, while the N-isopropyl substituent enhances activity in the N-phenyl-derived compounds. Certain substituents on the phenyl ring of both analogs greatly affect insecticidal potency of the carbamate esters. Also, some alkyl substituents (especially, a,cx-dimethyl and a-cyclopropyl groups) on the benzylic carbon of the benzylamine series enhance toxicity. The a,a-dimethyl branching of the N-benzyl carbamate approximates the steric shape given by the gemdimethyl group for conventional cyclopropane ring-containing pyrethroids. The N-benzyl compounds are significantly synergized by ...

The Relationship of Collegiate Television News Curricula With the Employment Marketability of Television News Graduates

Description: This study examined the relationship the television news sequence at four-year colleges and universities has with the employment marketability of those students who major in television news. Both vocational and academic approaches were examined. Three factors were taken into consideration: if the completion of any television news curriculum aids in the television news graduate's employment marketability, if the television news curriculum has merit when weighed against work experience without completion of such a discipline, and if another academic sequence might better prepare the aspiring television journalist. The study is significant in that the field of television news has been glutted in recent years by an influx of graduates who believe that the work is glamorous and exciting. Many graduates lack the basic verbal and mechanical skills to compete in the job marketplace. The first two chapters discuss the research problem and the factors comprising it. Details of the research design follow, dividing the study into an assessment of the problem and the analysis of the results of a questionnaire that was mailed to 213 television news anchors selected through a stratified random process. A background chapter on various television news curricula is included, with numerous books and periodicals cited. Educational profiles of selected network news anchors are also featured. Almost 60 percent of the local news anchors contacted completed and returned the questionnaires. The nominal data is discussed and presented in tabular form; the data is also analyzed through a series of cross-tabulations using specific demographical information and responses. Findings of the survey indicate that the television news sequence does not appreciably aid the graduate in securing employment, that practical experience outweighs the merits of completing such a sequence, and that the aspiring television journalist might benefit more from a concentration in the liberal arts.

An Exploratory Field Study of Adolescent Consumer Behavior: The Family Purchasing Agent

Description: An exploratory field study was conducted to examine internal and external factors that influence adolescents' consumer behavior when serving as the family purchasing agents. Demographic, lifestyle, and marketing activities were examined to determine the influences that affect whether the adolescent will purchase the preferred family brands or other brands. Participating adolescents were sent by their parents to the grocery store on two separate occasions to purchase four preselected grocery items. The brands purchased were recorded and compared to the preferred brand names provided by the parents. While no statistical significance was found, occasional trends were observed. The analysis indicated that adolescents who experience a pluralistic family communication style will purchase products other than the preferred household brands. Adolescents who are exposed to television and radio tend to deviate more from the preferred family brands more often than do adolescents with less media exposure. Adolescents who work are more likely to go to the grocery store more often for their families than do nonworking adolescents. Also, adolescents seem to possess a price sensitivity to both high and low-involvement grocery items.
