Remanufacturing is an industrial process where used products are restored to useful life. This dissertation describes how products can be designed to facilitate the remanufacturing process. It also describes how the remanufacturing processes can be improved to be more efficient. When comparing remanufacturing with other end-of-life scenarios, it is hard from an environmental perspective to determine which scenario is preferable. This research has shown that remanufacturing is preferable to new manufacturing from a natural resource perspective. With remanufacturing the efforts that initially was used to shape the product part is salvaged. Furthermore, it has been found that it is environmentally and economically beneficial to have products designed for remanufacturing. To avoid obsolescence, the products must be easy to upgrade with new technology in the remanufacturing process. In this dissertation, a generic remanufacturing process is described with all included steps that are needed to restore the products to useful life. In order to make the remanufacturing process more efficient, the products need to be adapted for the process. Therefore, the preferable products properties facilitating each step in the generic remanufacturing process have been identified. A matrix (RemPro) was created to illustrate the relation between each and every generic remanufacturing step and the preferable product properties. Remanufacturing case studies have shown that the companies performing remanufacturing often have problems with material flows, use of space and high inventory levels. This is often due to the uncertainties in the quality and the number of cores (used products) that will arrive at the remanufacturing plants. To overcome these problems, the remanufacturers need to achieve a better control over the product’s design and use phase, i.e. the life cycle phases that precede the remanufacturing process. This control is best performed by the original equipment manufacturers (OEMs). Furthermore, it has been found that Swedish manufacturers often have a weak relation between its environmental management systems and product issues, such as design for environment/remanufacturing. Design for environmental/remanufacturing aspects should be a crucial part of the manufacturers environmental management systems (EMSs) as the products stand for much of the material flows at the manufacturing companies. If the external auditors address the manufacturers to have a life cycle perspective on their business the manufacturer would be more likely to adapt the remanufacturing aspects in their environmental management systems.

Higher education institutions are always directed through policy reforms to promote graduates employability by developing skills in students that contribute to human capital. This interest in employability through education system in the development of skills reflects is part of human capital theory. Considering this, underlying research investigates the expectation-performance gap in the development of generic skills for the purpose of employability offered by the accounting institutes of Pakistan. For the purpose of answering the research question, this research, adopted the theoretical framework of ‘expectation-performance gap’ by Bui and Porter and analysed it within the context of Pakistan. Adoption of this theoretical framework implies the evaluation of three constituent factors as research objectives; the ‘expectation gap’ (reflecting the differences in the expectations of accounting educators and employers), the ‘constraints gap’ (limiting factors to develop generic skills into the student learning process) and the ‘performance gap’ (reflecting the ineffectiveness of teaching activities). However, there is also a fourth objective, that is, to evaluate an outline of the ‘skills acquisition framework’ considering the context of Pakistan’s accounting job-market. Principally this research adopts the survey strategy of a questionnaire with closed-ended questions in order to collect the data. But for the purpose of refining the content of the questionnaire for relevance to the context of Pakistan there are also cognitive interviews. Thus, this research entails a mixed-method approach. The qualitative data from the interviews was analysed using content analysis, thematic analysis and textual analysis. Whereas the quantitative data from the questionnaires was analysed using numerous statistical techniques such as Mann-Whitney U-test, Independent sample t-test, Statistical mean and Principal Component Analysis. The findings related to the ‘expectation gap’ were that there are 19 skills where the accounting educators have dissimilar expectation from employers in terms of skill base education, such skills include decision making, economics, ability to analyse and reason logically, teamwork etc. The findings related to the ‘constraints gap’ were that there are 6 constraining elements which are prevailing within the context of professional accounting education, such constraints include ‘training organisations are not following standard procedures to develop skills in students’, ‘people (potential students) have misperception about accounting education’, 'enrolling students have weak academic background', ‘inadequate stipend offered by training organisations to trainees’, ‘accounting institutes are not appreciating teaching activities, and lack of training opportunities for academics’. The findings related to the ‘performance gap’ were that there are 24 skills where the accounting educators found to be ineffective in the development of skills in students as expected by employers for employment purpose, such skills include inter or multidisciplinary perspective, financial risk analysis, think and behave ethically, independent thinking etc. From the perspective of the ‘skills acquisition framework’, overall 6 skills components were identified from the perspective of Pakistan's accounting job-market, such skills components include appreciative skills, interpersonal skills, technical and functional skills, organisational and business management skills, personal skills and professional skills. Considering the novelty of the adopted theoretical framework (expectation-performance gap by Bui and Porter, 2010) there was a related paucity of literature employing it for empirical investigation using the questionnaire based approach. Therefore, this research provides such theoretical underpinning to this framework that now enables it to be used within the questionnaire based approach. Further this research has described all the generic skills used in this study from the accounting disciplinary perspective and highlights the constraining elements that are assumed to limit the ability of professional accounting institutes. This research also provides a skill acquisition framework which could be used as a reference point for new entrants to the accounting job-market.

To deliver the type of marketing graduate that meets industry demand necessitates that marketing curricula content be continuously updated to keep pace with the dynamic marketing environment. One of the major trends influencing the twenty-first century marketing environment is the advent of the Internet and substantial growth in Internet usage and Internet-based commerce. Not only is the Internet driving major marketing environmental change, it is also emerging as a new marketing tool of significant potential. The widespread implications of the Internet to marketing is making it increasingly necessary for general marketing practitioners, even those not actively engaged in Internet-based commerce, to be equipped with an understanding of Internet marketing principles. For marketing education to remain relevant in the twenty-first century, it is essential that Internet marketing content elements be included in undergraduate generic marketing curricula. The first step in this process, and the one addressed by this study, is to identify and reach consensus on which Internet marketing content elements are relevant to generic undergraduate marketing students. The primary purpose of -this study w a s t a develop an empirically derived inventory o f Internet marketing content elements relevant for inclusion in generic undergraduate marketing programs, based upon both marketing academic and marketing practitioner perspectives. Five focal questions were asked and answered by the study. Which Internet-driven marketing environmental changes do marketing academics consider relevant to generic undergraduate marketing students? Which principles guiding the use of Internet as a marketing tool do marketing academics consider relevant to generic undergraduate marketing students? What do marketing academics consider to be the most suitable approach to implementing Internet marketing principles within higher education undergraduate business programs? What do marketing academics consider to be the relevant Internet marketing learning outcomes for generic marketing students at undergraduate level? Do marketing practitioners hold the same opinion as marketing academics regarding research questions one, two, three and four? For the purpose of this study, research was undertaken amongst two groups of respondents. Firstly, a census of the marketing faculties/departments of each of South Africa's public higher education institutions was taken at the end of 2004. Secondly, a non-probability, judgment sample of marketing practitioners, employed in those companies listed on the Johannesburg Stock Exchange (JSE), that engage in marketing activities and which are operational in the South African market was taken at the start of 2005. The questionnaire requested respondents in both samples to indicate the relevance of five identified Internet-driven marketing environmental changes and twenty-four identified principles guiding the use of the Internet as a marketing tool to generic undergraduate marketing students. Further, both samples were requested to select the approach they judged to be the most suitable in implementing Internet marketing principles within undergraduate business programmes. Respondents in both samples were also requested to indicate which Internet marketing learning outcomes they believed. To be relevant generic undergraduate marketing student addition to both samples were asked to provide certain demographical data. The findings indicate that both the Internet-driven marketing environmental change's construct and the principles guiding the use of the Internet as a marketing tool construct to be relevant to generic undergraduate marketing students. The findings further suggest that Internet marketing content elements should be integrated into existing marketing subject offerings. Regarding the learning outcomes, the findings indicate descriptive Internet marketing principles to be the overriding learning outcome. / Thesis (Ph.D. (Business Management))--North-West University, Vaal Triangle Campus, 2005.

A vast amount of usable electronic data is in the form of unstructured text. The relation extraction task aims to identify useful information in text (e.g., PersonW works for OrganisationX, GeneY encodes ProteinZ) and recode it in a format such as a relational database that can be more effectively used for querying and automated reasoning. However, adapting conventional relation extraction systems to new domains or tasks requires significant effort from annotators and developers. Furthermore, previous adaptation approaches based on bootstrapping start from example instances of the target relations, thus requiring that the correct relation type schema be known in advance. Generic relation extraction (GRE) addresses the adaptation problem by applying generic techniques that achieve comparable accuracy when transferred, without modification of model parameters, across domains and tasks. Previous work on GRE has relied extensively on various lexical and shallow syntactic indicators. I present new state-of-the-art models for GRE that incorporate governordependency information. I also introduce a dimensionality reduction step into the GRE relation characterisation sub-task, which serves to capture latent semantic information and leads to significant improvements over an unreduced model. Comparison of dimensionality reduction techniques suggests that latent Dirichlet allocation (LDA) – a probabilistic generative approach – successfully incorporates a larger and more interdependent feature set than a model based on singular value decomposition (SVD) and performs as well as or better than SVD on all experimental settings. Finally, I will introduce multi-document summarisation as an extrinsic test bed for GRE and present results which demonstrate that the relative performance of GRE models is consistent across tasks and that the GRE-based representation leads to significant improvements over a standard baseline from the literature. Taken together, the experimental results 1) show that GRE can be improved using dependency parsing and dimensionality reduction, 2) demonstrate the utility of GRE for the content selection step of extractive summarisation and 3) validate the GRE claim of modification-free adaptation for the first time with respect to both domain and task. This thesis also introduces data sets derived from publicly available corpora for the purpose of rigorous intrinsic evaluation in the news and biomedical domains.

Abstract Background The South African Healthcare landscape has changed dramatically over the last two years with the implementation of mandatory substitution, single exit pricing and prescribed minimum benefits. The private market for medicines is becoming more competitive and commoditized. Between July 2004 and June 2005 there were 119 generic registrations at the Medicines Control Council. In the US and Canada research has been conducted on the change in prescribing behaviour induced through incentive based formularies and the impact of generic medicines on healthcare costs. This research protocol aims to build on this body of knowledge by analysing sales trends within a therapeutic class after the launch of a generic molecule in the same class. This research investigates how the introduction of generics may impact the growth of the innovator molecules and subsequent generics. The therapeutic class Acid Pump Inhibitors has been selected. Method Unit sales of Proton Pump Inhibitors are drawn monthly from sales in the total private market. They are then grouped by molecule and comparisons are drawn between the originator and it’s generic to determine association. This is also done at the aggregate level where the originators form one group and generics the second group. Each aggregate group’s average growth in the therapeutic class is then calculated to determine the aggregate group’s evolution index. Data Analysis Data is analysed through descriptive and interpretative statistics. The descriptive statistics establish a relationship between generisized molecules and the non generisized molecules. A t-test for two independent means is used to test the hypothesis that the non generisized molecules in the therapeutic class have a significant higher growth. Conclusion The results demonstrate that the number of units sold of the generisized molecules increase as they become more affordable, however contrary to intuition the number of iv units sold of the non generisized molecules also increase. The research shows that there is a statistically significant greater growth, albeit on a smaller base, of the non generisized molecules over generisized molecules.

This mixed method study sought to explore the perceptions of key stakeholders in education, on the role and contribution of ICT in Scottish secondary schools towards generic skills development among pupils for post school transitions. The timing of this study coincided with a period characterised by contextual pressures globally, marked with technology changes, youth unemployment and curriculum reviews. A review of literature was conducted systematically to evaluate the explicit permeation of ICT in Scottish schools. A sequential mixed method design was adopted for the two phased study commencing with a convenience sampling technique for the first phase, involving 1364 upper secondary school pupils from all eight schools, 64 teachers and the 17 employers in one local Council in Scotland. A purposive sampling technique was applied to select two sample schools for the second phase, based on best use and practices of ICT. Questionnaires were administered online and in person at the first phase, followed by a semi structured interview at the second phase. SPSS was used for descriptive statistics, correlation analysis and one way Anova, while Nvivo 10 software was used for thematic analysis from the interview transcript. The study offers a framework for personalisation starting with identification of pupils’ ability and ICT skill level at inception classes, followed by a personalised learning design incorporating pupils’ interest, ability and post school destination. The study also proposes separate roles for teachers and policy makers in order to maintain teachers’ autonomy, as policy makers’ interference has been identified to have an impact on teachers’ professionalism, effectiveness and confidence necessary for imparting generic skills in pupils. A series of recommendations are provided for future research, including a longitudinal evaluation of generic skills acquired from individual school subjects through the upper school years to post school destination, to ascertain effective transfer and sustainability of generic skills.

Masters of Public Health - see Magister Public Health / Overreliance on donor supported health programs has crippled many African countries and there is inadequate long-term planning on the future sustainability of health systems. In the age of uncertainty in global politics and global economy, the future of these donor funded programs is also uncertain. It is imperative for African nations to begin to take responsibility for their health programs. In as much as the name “donation” suggests that something is given free of charge, in actual sense this may not be the case due to hidden costs attached. In medicine access, the hidden costs are the supply chain costs including cost for clearance, storage and distribution of such medicines which are charged as a percentage of claimed commodity costs on donors’ or suppliers’ invoices. Since the medicines donated are in originators’ brands, the invoiced prices are high thus supply chain costs are high as well. In some cases, it is thought that the hidden costs are higher than the cost of medicines had they been sourced locally as generics. The aim of this research was to assess and determine the hidden supply chain costs associated with the four medicine donation programs supporting the Tanzania Neglected Tropical Diseases Program and inform policy decision on optimal financing options for the program Methodology The cost analysis of the two options was undertaken from a payers’ perspective which in this case is the Government of Tanzania (Ministry of Health). Data was collected on both product and supply chain cost drivers incurred in the medicine donation programs from July 2014 to June 2017. Costs of the current mechanism were obtained from the program’s quantification reports and transaction data for the study period. Transactional data was obtained from shipment documents including sales invoices, parking list, proof of delivery and goods receiving notes were evaluated for actual quantities shipped, commodity prices and other supply chain cost. To verify the actual supply chain cost charged by the program, both the official bills from Medical Stores Department (MSD) to the program and the electronic bills available at MSD electronic database covering the study period were studied.

This thesis investigates development of generic capabilities in an RMIT undergraduate logistics degree program. Generic capabilities are those general graduate attributes that are not specifically discipline-focused, examples being communication and teamwork skills. A major research objective of this thesis is the extent to which graduates perceived that generic capabilities were developed in their RMIT logistics undergraduate program, specifically in a cross-cultural context spanning a range of organisations differing in size and ownership structure. The thesis involves two studies. In Study 1 managers from eight organisations, ranging in size from multi-national to small public and private (family-owned) companies were interviewed to develop a series of qualitative organisational case studies using grounded theory methodology. Study 2 is a quantitative survey of 31 Australian and 25 Asian (Singapore and Hong Kong) logistic graduates from 1996 to 2002. In Study 1, generic capabilities rankings in different organisations varied, depending on whether managers being interviewed were operational or human resource management specialists, but there was general agreement that communication, problem-solving, initiative and enterprise, and teamwork skills were highest priority. Study 2 results indicate that the views of both Asian and Australian graduates are in line with the management rankings, and are consistent with those reported by Australian and OECD government and industry research organisations. Both graduate groups agree that generic capabilities are covered in the RMIT logistic program, but ratings are generally in an 'adequate' to 'good' range, with no outstanding features. Although cultural diversity in the student body is seen as a major benefit, there are little data indicating a high level of Australian and Asian student networking, and a number of respondents are critical of a lack of international focus in the present program. A major issue is a n eed for more emphasis on presentation and problem-solving skills so graduates are able to carry through a project from initiation to completion.

<p>We study the power series ring R= K[[x₁,x₂,x₃,...]]on countably infinitely many variables, over a field K, and two particular K-subalgebras of it: the ring S, which is isomorphic to an inverse limit of the polynomial rings in finitely many variables over K, and the ring R', which is the largest graded subalgebra of R.</p><p>Of particular interest are the homogeneous, finitely generated ideals in R', among them the <i>generic ideals</i>. The definition of S as an inverse limit yields a set of <i>truncation homomorphisms</i> from S to K[x₁,...,x_n] which restrict to R'. We have that the truncation of a generic I in R' is a generic ideal in K[x₁,...,x_n]. It is shown in <b>Initial ideals of Truncated Homogeneous Ideals</b> that the initial ideal of such an ideal converge to the initial ideal of the corresponding ideal in R'. This initial ideal need no longer be finitely generated, but it is always <i>locally finitely generated</i>: this is proved in <b>Gröbner Bases in R'</b>. We show in <b>Reverse lexicographic initial ideals of generic ideals are finitely generated</b> that the initial ideal of a generic ideal in R' is finitely generated. This contrast to the lexicographic term order.</p><p> If I in R' is a homogeneous, locally finitely generated ideal, and if we write the Hilbert series of the truncated algebras K[x₁,...,x_n] module the truncation of I as q_n(t)/(1-t)ⁿ, then we show in <b>Generalized Hilbert Numerators </b>that the q_n's converge to a power series in t which we call the <i>generalized Hilbert numerator</i> of the algebra R'/I.</p><p>In <b>Gröbner bases for non-homogeneous ideals in R'</b> we show that the calculations of Gröbner bases and initial ideals in R' can be done also for some non-homogeneous ideals, namely those which have an <i>associated homogeneous ideal</i> which is locally finitely generated.</p><p>The fact that S is an inverse limit of polynomial rings, which are naturally endowed with the discrete topology, provides S with a topology which makes it into a complete Hausdorff topological ring. The ring R', with the subspace topology, is dense in R, and the latter ring is the Cauchy completion of the former. In <b>Topological properties of R'</b> we show that with respect to this topology, locally finitely generated ideals in R'are <i>closed</i>.</p>
