A Study of the Implementation of the Swaziland Integrated Science Programme
No full textIn 1974 the first year of the Swaziland Integrated Science Programme (SWISP) was introduced in the schools of Swaziland. SWISP was designed as an activity oriented science education program for the junior secondary schools.As SWISP was developed, a strategy for the implementation of the program was also developed. Part of this strategy was to ensure that teachers physically implemented the program by carrying out the procedures outlined by the curriculum development team. An additional part of the strategy was that the teachers of the course gain an understanding of the philosophy of the program; the total strategy, therefore, was a combination of these two. This strategy involved: three years of writing, rewriting, pilot testing, and in-service workshops involving the Swaziland Ministry of Education, the sub-committee of the science panel, and the most important, science teachers throughout the country.One result of this work was the SWISP teacher's manual, a multi-volume detailed description of the program which included information that focused on three basic areas: (1) Organization of classrooms and laboratories including equipment and materials necessary to teach SWISP; (2) Philosophy of the program; (3) Classroom procedures for teachers and students.The central purpose of the study was to describe the present status of the three basic areas described in the teacher's manual as they are being practiced in the junior secondary schools of Swaziland according to the strategy for implementation.Judgments regarding the implementation may be viewed on two levels. The first level is operational in which teachers attempt to carry out the recommended procedures set forth in the teacher's manual to the best of their abilities usually under some adverse conditions such as lack of equipment and materials and overcrowded classrooms.The second and more comprehensive level of implementation of SWISP, while including the following of the procedures set forth in the teacher's manual, implies that the teachers have a commitment to the program which goes far beyond the first level of implementation. Teachers operating on this second level of implementation have a total understanding and commitment to the philosophy of the program and everything these teachers do in the classroom or laboratory reflects this commitment.The design of the study was based on three methods of gathering data. First a questionnaire was designed in the United States and administered to the 167 science teachers involved with teaching SWISP in Swaziland. The second method used in the study was a series of short site visits at which time a checklist and an observation guide were completed. The third method was a series of intensive site visits which involved observation of classes and focused interviews with junior secondary science teachers.From discussions with and observations of the teachers in the short and intensive site visits as well as from data collected from the questionnaire, it is evident that the majority of the SWISP teachers are carrying out the recommended procedures in the teacher's manual and are, therefore, operating on the first level of implementation. However, there were three problems mentioned by the science teachers and observed by the researcher: lack of space and equipment for small group work; lack of money for replacement and/or repair of equipment; and a feeling by the teachers that there is not enough time to revise (review) before the Junior Certificate examination.Because of these problems it can be stated that the second and more comprehensive level of implementation has not been achieved.Made available in DSpace on 2014-12-12T19:57:05Z (GMT).

Molecular Genetics in Rhodopseudomonas Sphaeroides: Transformation, Plasmids, and Gene Cloning
No full textA Tris-dependent transformation system was developed for R. sphaeroides. Washing the cells with 0.5M Tris-buffer, pH 7.2, at 0(DEGREES)C prior to exposure to DNA was found to be necessary for inducing a competent state for DNA uptake. Polyethylene glycol (PEG) and Ca('2+) were also determined to be necessary components of this system and were added at the time of DNA addition to Tris-treated cells. The transformation method was most effective with plasmid DNA in the CCC configuration and frequencies as high as 1 x 10('-5) transformants per viable cell were achieved using RSF1010 DNA, although other plasmids, such as pRK290 and RP4 were capable of transforming Tris-treated cells. A versatile cloning vector, pUI81, was constructed from RSF1010 and a pBR322 derivative, pSL25 and shown to be effective in transforming Tris-treated R. sphaeroides.The indigenous, cryptic plasmids of R. sphaeroides 2.4.1 were structurally analyzed. Ten strains were examined for plasmid content and the molecular relationships among them by agarose gel electrophoresis and filter hybridizations. It was found that all strains contained at least one high molecular weight plasmid, and some had as many as six. The sizes in kilobases (kb) ranged from 42 to 150 and the total plasmid content in some strains accounted for as much as 18% of the genome. All of the larger (> 42 kb) plasmids among the various strains were found to be homologous with each other, although the homology was restricted primarily to the largest (114 kb) plasmid of strain 2.4.1. The 2.4.1. 42 kb plasmid was analyzed in detail and a partial restriction enzyme map was determined. Methods for the high yield preparation of pure plasmid DNA from the various strains were also developed and a procedure for fractionating bulk plasmid DNA was also devised.The genes for the ribulose-1,5,-bisphosphate carboxylase and the nitrogenase enzyme complex of R. sphaeroides 2.4.1, as well as for Rs. rubrum, R. palustris and R. capsulata, were identified and located by probing chromosomal digests with the nif genes from K. pneumoniae and the carboxylose gene from R. rubrum. The 2.4.1 carboxylase gene on a 2800 bp EcoRI-Bam HI fragment was subsequently cloned out of low melting point agarose onto pBR322 and transformed into E. coli strain SF8.Made available in DSpace on 2014-12-16T06:12:50Z (GMT).

Leadership characteristics, functions, incentives, inhibitors, and development experiences as perceived by selected home economists
No full textThe importance of leadership development in the profession of home economics ranks as a high priority. The American Home Economics Association discussed leadership development at the 1989 Strategic Planning Conference, appointed a national Leadership Development Committee, and has planned workshops and conferences on this topic. Journal articles indicate high interest and recognition is given to outstanding leaders."The descriptive study compiled demographic data regarding the 125 recognized ""Leaders"" of the American Home Economics Association from 1984 through 1989 and investigated their perceptions regarding leadership characteristics, functions, incentives, inhibitors, and developmental experiences. Based on a review of literature, a questionnaire was developed to answer the research questions. Respondents indicated relative importance of various criteria using a Likert scale."Data were tabulated and analyzed from the population which provided a 91% response rate. Respondents included 96% female; 53% married; 13% divorced or widowed; 34% never married; 58% had no children; 90% had a mentor; 73% had a doctoral degree.Means, standard deviations, and percentages were compiled on the five major research topics on which perceptions were requested. The three most essential characteristics in leadership development identified were knowledgeable, communicative, and committed. The three most important leadership behaviors were motivating others, inspiring others, and developing clear goals. Incentives stimulating leadership development included desire to make a worthwhile contribution to society, desire to make a worthwhile contribution to the home economics profession, and opportunity to work with other capable professionals. Factors inhibiting leadership development were lack of vision and dedication to the profession, lack of personal motivation, and lack of time due to career and family. Experiences contributing most to leadership growth were committee/officer responsibilities, continued desire for self-development, and involvement in professional organizations.This study has implications for the profession of home economics, its professional organization, and individual home economists. Educational sessions and curriculum can be planned to promote leadership development activities. Leadership development is of extreme importance and can be accomplished in numerous ways when a positive approach is followed.Made available in DSpace on 2011-05-07T12:54:53Z (GMT).

Adaptive methods for meteor burst communications
No full textWe investigate various methods for making efficient use of the time-varying power received by radio reflection from meteor trails, including applications of variable-rate coding and variable-rate transmission. For variable-rate coding, the code rate is changed periodically during the life of the trail in an attempt to match the rate to the instantaneous signal power. For a system that employs packet transmissions, we develop an algorithm that determines the number of codewords and the rate for each codeword that maximize the probability of successful decoding for the packet. The optimal packet configuration is a function of the length of the message and the underdense trail decay constant. It is shown that the signal power required to obtain a given probability of success is significantly smaller for optimal variable-rate coding than for fixed-rate coding.We also consider the incorporation of variable-rate coding in automatic-repeat-request (ARQ) protocols. A variation of type-I hybrid ARQ called variable-rate type-I hybrid ARQ is introduced. For one implementation, measurements of the trail parameters are used to select the code rate, while, for another, the selection is based on previous decoding outcomes. The throughput for each implementation is compared with the throughput for optimal variable-rate type-I hybrid ARQ. It is shown that each implementation gives significantly larger throughput than fixed-rate type-I hybrid ARQ and ARQ without forward-error-correction. For type-II hybrid ARQ, code rate variation is inherent in the coding scheme. On the first transmission, the code is effectively of high rate, but if an additional transmission is required, additional redundant symbols are sent, and the code rate is effectively lower for each subsequent transmission. The throughput for type-II hybrid ARQ is compared with the throughput for variable-rate type-I hybrid ARQ. For variable-rate transmission, the pulse length is changed periodically, based on measurements of the signal power at the destination. We have determined the maximum reliable throughput that can be obtained for variable-rate transmission, when the source and destination have perfect knowledge of the signal power and can choose from an infinite number of pulse lengths for each pulse.Made available in DSpace on 2011-05-07T12:57:55Z (GMT).

An investigation of teacher-student interactions during standardized testing in elementary school classrooms
No full textThis is a case study that investigated intermediate elementary school teachers' behaviors and attitudes toward the Metropolitan Achievement Test, 6th ed. (MAT6). The purpose of this study was to investigate the testing behaviors and attitudes of elementary school teachers toward the MAT6. From a Virgin Islands school district, six regular classroom fifth-grade teachers were randomly selected from three similar schools for classroom observation while they administered the MAT6 in October 1992. A total of 29 of the district's fifth-grade teachers responded to a 24-item objective and open-ended questionnaire.Four techniques used to collect the data were: (a) classroom observations and note-taking of six fifth-grade teachers' administration of the MAT6, (b) audio recording of the teachers' administration of the MAT6, (c) interviews with the six observed teachers, and (d) survey of the entire population of regular fifth grade classroom teachers. The findings suggested that teachers believe: (a) the October MAT6 testing is too early in the academic year to evaluate students' grade level achievements, (b) the current MAT6 testing situation is only a diagnostic measure and not an evaluative tool, since there is no post testing at the end of the school year, (c) neither teachers nor students take the MAT6 testing very seriously, (d) students do not possess adequate testing skills to effectively take objective tests, and (e) students' MAT6 results might improve if test-taking skills are integrated in all content lessons, starting from the second grade.Included are the opinions of 29 fifth-grade teachers, their suggestions for improving test preparations, and ideas on instructing specific test-taking skills for elementary school students. The teachers expressed opinions indicated that they do not possess a good understanding of the importance of standardized testing in instruction and curriculum.Made available in DSpace on 2011-05-07T13:27:31Z (GMT).

Studies in molecular recognition. Part I. Expanded molecular tweezers: Design and synthesis of novel receptors. Part II. Molecular self-assembly: Use of carboxylic acids as self-assembly elements
No full textIn Part I, the design, synthetic approaches, and complexation studies of molecular tweezers possessing spacer units 7 A are discussed. A general feature of these approaches is the use of the Friedlander reaction to generate the spacer unit. A tweezer utilizing 2,7-dimethoxyacridine as the chromophore with an inter-chromophore distance of 9.7 A was synthesized. This expanded tweezer was found to bind 2,4,5,7-tetranitrofluorenone (TENF) with a K\sb{\rm a} 10 M\sp{-1}. Progress in the synthesis of a water soluble tweezer with an expanded spacer unit is also reported.In Part II, the design and synthesis of a novel molecular tweezer which utilizes carboxylic acids as self-assembly elements is reported. The key feature of the synthesis was the Suzuki coupling of the bis(boronic acid) derived from 2,12-dibromo-7-(4 \sp\prime-methoxyphenyl)-5,6,8,9-tetrahydro-dibenz (c, h) acridine and 5-methylisophthalate triflate. The addition of a solubilizing group and hydrolysis of the methyl esters gave a molecular tweezer with four carboxylic acids which was soluble in organic solvents. Preliminary investigations suggest that the tweezer forms a well-defined aggregate in CH\sb2Cl\sb2.Made available in DSpace on 2011-05-07T13:47:27Z (GMT). No. of bitstreams: 2
