Knowledge production practices in higher institutions of learning in Zambia: a case of the University of Zambia

Kanyengo, Christine Wamunyima January 2020 (has links)
The core business of higher education institutions such as universities is knowledge production. This is achieved by conducting research which results in various research products being produced, as well as through teaching and the production of graduates. The main objective of the study was to explore and describe knowledge production practices and their attributes within a university environment at the University of Zambia. The study's major contribution to knowledge is that it indicates to what extent this objective is achieved. A mixed methods case study approach that used both quantitative and qualitative research methodology was adopted for the study. The mixed methods analysis framework was based on grounded theory, bibliometric techniques, and concurrent triangulation. The site of investigation was the School of Medicine at the University of Zambia. The sampling technique also adopted a mixed methods approach by using purposive, availability and stratified purposeful sampling to sample the respondents. The PubMed/Medline database, academic staff, key informants and the documents reviewed all served as the key sources of information for the study. Data obtained from PubMed/Medline, questionnaires and semi structured interviews were quantitatively analysed using the Statistical Package for the Social Sciences (SPSS) software, while the more qualitative information that was gleaned from open-ended questions, semi-structured interviews and documentary sources was analysed thematically. The subject analysis of PubMed/Medline articles was done using the VOSviewer software and Microsoft Excel. The findings reveal that the yearly research output from 1995 to 2015 was 281 scholarly papers in 159 journals. The lowest number of papers published were recorded in 1997, 2000, and 2004 while the years 2013, 2014 and 2015 show the highest number of papers per year; and the highest was recorded in 2015. It was found that, except in 1997 and 2000, most of these papers were authored by more than five researchers. This indicates a high degree of collaboration. The journals in which the academic staff were publishing in emanated from all over the world; Asia, Africa, Europe and North America. The journals themselves are also a combination of both high impact factor journals such as the PLoS One, American Journal of Tropical Medicine and Hygiene, International Journal of Tuberculosis and Lung Disease, The Lancet, Malaria Journal and those with no impact factor like the Medical Journal of Zambia. The results indicate that the respondents mostly investigated and published in subject fields related to diseases most prevalent in Zambia, i.e. HIV and Aids, Malaria and Tuberculosis. In addition, the findings indicate that the majority of the academic staff were born after 1960 (73%), with high digital information retrieval skills (95.2%), and with their research output published mainly in journals. The knowledge was produced for various reasons: 85.4% for research purposes, 80.5% for academic promotion, 80.5% for production of knowledge, 73.2% to improve teaching, 61% to provide evidence, 51.2% to change practice, 41.5% to improve policy, 41.5% for personal advancement, and 24.4% for research funding. The knowledge was produced ethically, advancing scholarship, and deemed to be beneficial to society. The overall conclusion drawn from the study is that the knowledge productivity of the School of Medicine has steadily increased over the years and that this is supported by various institutional policies. Additionally, there is increased collaboration with persons outside the continent, whilst there is less collaboration with countries in Africa. The key recommendation for the School of Medicine is that it should work with and within the various layers of the university's institutions such as the Library, Directorate of Research and Graduate Studies, University of Zambia Press, and the Centre for Information and Communication Technology. This would ensure that impediments to knowledge production, diffusion and utilisation are mitigated.

Egghead & Twinkie: Continuing the Tradition of LGBTQ Micro-budget Cinema

Kambe Holland, Sarah 01 January 2022 (has links) (PDF)
Egghead & Twinkie is a micro-budget feature film created by Sarah Kambe Holland to satisfy the requirements for earning a Master of Fine Arts in the Feature Film Production program at the University of Central Florida. The film follows a mixed-Asian teenager as she comes out to her parents and embarks on a road trip to meet her online crush with the help of her nerdy best friend. The intention behind the project is to reduce fear surrounding the coming out process by portraying the experience through a comedic lens. The production team aims to continue a rich history of LGBTQ independent filmmaking through working within the confines of an exceedingly limited budget. Featuring animated elements, green screen effects, and twenty-two different shooting locations, this highly ambitious production required an abundance of problem solving and pre-planning in order to preserve the integrity of the original script and successfully adapt it for the screen. The following document describes the multi-year journey to create the film, from the development stage to the marketing strategy planned for its eventual distribution. For future scholars, this thesis serves as a record detailing how a team of independent filmmakers adapted and persevered in order to produce a feature in the middle of the COVID-19 pandemic.

Schwinger Pair Production and Fall to the Center

Sundaram, Sriram January 2019 (has links)
The classical field theory of Schwinger pair creation can be described using an effective Schrodinger equation with an inverted harmonic oscillator Hamiltonian. It is a well known fact that the inverted harmonic oscillator admits a canonical transformation to a Q.P type Berry-Keating Hamiltonian. In this thesis we demonstrate that the classical field theory of Schwinger pair creation has a hidden scale invariance described by the quantum mechanics of an attractive inverse square potential in the canonically rotated (Q,P) coordinates of the inverted harmonic oscillator. The quantum mechanics of the inverse square potential is well known because of the problem of fall to the center and the associated ambiguities in the boundary condition. It is also well known as a description of the physics of pair creation in the presence of an event horizon and black hole decay. We use point particle effective field theory (PPEFT) to derive the boundary condition which describes pair creation. This leads to the addition of an inevitable Dirac delta function with imaginary coupling to the inverse square potential, describing the physics of the source. This non-hermitian physics leads to the Klein paradox. The conservation loss is due to the charged pairs being produced during tunneling. / Thesis / Master of Science (MSc)

Aggregate Production Planning Techniques and Comparison

Mazaheri, Fariborz 01 January 1977 (has links) (PDF)
Aggregate production planning models are of the greatest importance to operations management, since these plans enable management to utilize the major resources at its command. In this report the structure of the aggregate planning problem and a number of different approaches are reviewed and presented. Approaches are classified in three categories: a) workforce smoothing models, b) production smoothing models, c) production and workforce models. The models are compared with respect to the cost structure, parameters estimation, forecast requirement, decision variables, computability and optimization techniques.

The Conradie Codec : the recoding of meaning in four of my stage adaptations

Conradie, Wilhelm 04 1900 (has links)
Thesis (MA)--Stellenbosch University, 2015. / ENGLISH ABSTRACT: In this thesis I attempted to analyse the four adaptations I created between 2004 and 2010. The first two products (texts and productions) were created in 2004 and 2005, while I was a student at the Stellenbosch University Drama Department. The third adaptation (text only) was created in 2007, while I was a freelance stage manager. In 2010, I collaborated with a choreographer for the first time to adapt a Shakespeare text into a dance theatre production. The process of adapting a text always starts with an interpretive reading. Extracting information and meaning from a text can also be referred to as ‘decoding’. In the process of creating the adaptation new meaning is written, or ‘encoded’, into the product that must in turn be decoded by the reader or audience member. A term for this decoding and encoding process that is often encountered in the field of video editing (an aspect of my current profession) is a ‘codec’. In video editing a codec is responsible for the decoding of a computer file into a video program that a viewer/audience can engage with, as well as the encoding of a video program into a file. Since I function as the ‘codec’ in these adaptation scenarios, I thought it appropriate to label my approach to the adaptation process, the ‘Conradie codec’. The aim of this reflexive study is to analyse my four adaptations, the processes as well as the products, in order to determine if such a codec truly exists. Research done in adaptation studies was presented in an attempt to define adaptation as both process and product – Linda Hutcheon’s A Theory of Adaptation was particularly useful. This created a framework for the study of each of the four adaptations in chronological order, according to the year in which they were created. The study also draws very generally on the principles of semiotics, especially with respect to the notion of coding. Firstly, the 2004 adaptation of Luigi Pirandello’s Six Characters in Search of an Author into Twintig akteurs op soek na ‘n [beter] Regisseur was analysed. This was followed by onsindroom (sic), an adaptation of August Strindberg’s A Dream Play. The third adaptation was iForest, which was created in 2007. This was an adaptation of (primarily) Eugene Ionesco’s The Killer. Lastly, the adaptation of Shakespeare’s Troilus and Cressida into When in Love… was studied. It was concluded that, while the ‘Conradie codec’ does exist and was applied in the creation of the four adaptations, its efficiency was limited – predominantly by time constraints. In all four the cases analysed the rehearsal process started when a complete draft of the adapted text was not yet finished. This put enormous pressure on the rehearsal process. While this is accepted when creating a workshop style production, more time is needed to develop the adaptation in order for it to be cohesive. By going through the process of analysing these four adaptations, the Conradie codec has been adapted (or updated) to version 2.0. / AFRIKAANSE OPSOMMING: In hierdie tesis het ek gepoog om my vier verwerkings tot op hede te analiseer. Die eerste twee produkte (tekste en produksies) was in 2004 en 2005 geskep terwyl ek ‘n student was. Die derde verwerking (slegs die teks) was in 2007 geskep terwyl ek ‘n vryskut verhoogbestuurder was. In 2010, het ek vir die eerste keer saam met ‘n choregraaf gewerk om ‘n Shakespeare teks te verwerk na ‘n dansteaterproduksie. Die verwerkingsproses van ‘n teks begin altyd met die lees van die teks op ‘n interpreterende wyse. Hierdie proses, om betekenis uit ‘n teks te ontgin, kan ook ‘dekodering’ genoem word. Tydens die verwerkingsproses word nuwe betekenis in die produk ingeskryf, of ‘geënkodeer’. Die leser of gehoorlid moet weer op hul beurt die nuwe produk dekodeer. Hierdie dekodering en enkodering word in videoredigering (‘n aspek van my huidige beroep) ‘n ‘codec’ genoem. In videoredigering is ‘n ‘codec’ verantwoordelik vir die dekodering vanaf ‘n rekenaarlêer na ‘n videoprogram wat deur iemand gekyk kan word, sowel as die enkodering vanaf ‘n videoprogram na ‘n leêr. Aangesien ek tydens die verwerkingsproses as die ‘codec’ funksioneer, het ek dit goed gedink om met die term die ‘Conradie codec’ vorendag te kom. Die doel van hierdie refleksiewe studie was om my vier verwerkings, die prosesse sowel as die produkte, te analiseer en sodoende te bepaal of so ‘n ‘codec’ wel bestaan. Navorsing op die gebied van verwerkings was voorgelê in ‘n poging om die konsep van verwerking as beide proses en produk te definieer – Linda Hutcheon se A Theory of Adaptation was ‘n nuttige bron gewees. Dit het gehelp om ‘n raamwerk vir die bestudering van elk van die vier verwerkings te skep – wat dan uitgevoer was in chronologiese volgorde. Die studie maak ook gebruik van die beginsels van semiotiek, in ‘n baie algemene wyse, veral ten opsigte van die begrip van kodering. Eerstens was die 2004 verwerking van Luigi Pirandello se Six Characters in search of an Author na Twintig akteurs op soek na ‘n [beter] Regisseur ontleed. Dit was gevolg deur onsindroom, ‘n verwerking van A Dream Play deur August Strindberg. iForest wat in 2007 geskep is, was ‘n verwerking van (hoofsaaklik) The Killer deur Eugene Ionesco. Laastens was die verwerking van Shakespeare se Troilus and Cressida na When in love… bestudeer. Die gevolgtrekking was dat daar iets soos die ‘Conradie codec’ bestaan en dat dit wel toegepas was in die skepping van die vier verwerkings. Die effektiwiteit daarvan was wel beperk – hoofsaaklik as gevolg van tydsbeperkings. In al vier die gevalle het die repetisieproses reeds begin voordat ‘n volledige weergawe van die teks voltooi was, wat enorme druk op die repetisieproses geplaas het. Terwyl dit aanvaarbaar is in die konteks van ‘n werkswinkelproduksie word meer tyd benodig vir die verwerking van ‘n teks om samehangend te wees. Deur die vier verwerkings te bestudeer, was die Conradie ‘codec’ self in die proses verwerk (of bygewerk) tot weergawe 2.0.

DYNAMIC PRODUCTION PLANNING WITH SUBCONTRACTING.

Wu, Yih-Bor January 1987 (has links)
This research is concerned with scheduling production over a finite planning horizon in a capacitated manufacturing facility. It is assumed that a second source of supply is available by means of subcontracting and that the demand varies over time. The problem is to establish the production level in the facility and/or the ordering quantity from the subcontractor for each period in the planning horizon. Firstly, the cost functions are analyzed and two types of realistic production cost models are identified. Then mathematical models are developed for two different problems. One is a single criterion problem aimed at minimizing the total production and inventory costs. The other is a bicriterion problem which seeks the efficient frontier with respect to the total cost and the number of subcontractings, both to be minimized, over the planning horizon. For each of the above, two methods, namely, a general dynamic programming approach and an improved dynamic programming approach (Shortest path method) are presented. Several results are obtained for reducing the computations in solving these problems. Based on these results, algorithms are developed for both problems. The computational complexity of these algorithms are also analyzed. Two heuristic rules are then suggested for obtaining near-optimal solutions to the first problem with lesser computation. Both rules have been tested extensively and the results indicate advantages of using them. One of these rules is useful for solving the uncapacitated problem faster without losing optimality. The above results are then extended to other cases where some of the assumptions in the original problem are relaxed. Finally, we studied the multi-item lot-sizing problem with the subcontracting option and proposed a heuristic for solving the problem by the Lagrangean relaxation approach. We demonstrated that with an additional capacity constraint in the dual problem the feasible solution and the lower bound obtained during each iteration converge much faster than without it. After testing some randomly generated problems we found that most of the solutions obtained from the heuristic are very close to the best lower bound obtained from the dual problem within a limited number of iterations.
