The prevalence of Protein-Energy Malnutrition (PEM) in South Africa has been welldescribed in previous research studies and yet little is known about the nutritional status of toddlers in the Vosloorus Township. Using the research questions as the conceptual framework for the study, an exploratory descriptive survey was conducted to determine. • What factors give rise to malnutrition in the Vosloorus Township? • Why do toddlers on the PEM Programme fail to achieve their expected target weight? Data was collected by means of structured interviews from a sample of 50 mothers in the Vosloorus Township whose toddlers were on the PEM Programme. The fmdings indicated that the poor socio-economic conditions of the majority of households, especially unemployment, low levels of education and ignorance, contributed towards the development of malnutrition amongst toddlers and their failure to thrive on the PEM Programme. Recommendations to reduce levels of malnutrition and transform existing nutrition programmes were made. / Health Studies / M.A. (Nursing Science)

Die lebenden Organismen sind für eine wissenschaftliche Analyse zu kompliziert, wenn man sie als Ganzes und in ihrer vollen Komplexität betrachtet. Die vorliegende Arbeit behandelt die topologischen Eigenschaften von zwei wichtigen Teilen der lebenden Organismen: die metabolischen und die regulatorischen Systeme. Topolgische Eigenschaften sind solche, die durch die Netwerkstruktur bedingt werden. Ein Signalsystem ist eine spezielle Art von regulatorischem System. Zwischen den metabolischen und Signalnetzen gibt es wichtige Unterschiede, die ihre Behandlung in unterschiedlicher Weise erfordert. In der metabolischen Pfadanalyse ist das Konzept der elementaren Flussmoden bereits als ein passendes Instrument für die Charakterisierung der einfachsten essentiellen Wege in biochemischen Systemen etabliert. Wir untersuchen die Eigenschaften und Vorteile dieses Konzepts in einigen besonderen Fällen. Zuerst untersuchen wir die vielfach vorkommenden Enzyme mit niedriger Spezifität (z.B. Nukleosiddiphosphokinase, Uridinkinase, Transketolase, Transaldolase). Sie können parallel verschiedene Substrate und Produkte umwandeln. Auch die Enzym-Mechanismen sind vielfältig, wie wir mit dem Reaktionsschema für bifunktionelle Enzyme veranschaulichen. Wir betrachten dabei nur den Fall, dass ein bestimmtes aktives Zentrum mehrere Reaktionen katalysiert. Der Fall, dass das studierte Enzym mehrere solche aktiven Zentren hat, kann in den Fall mehrerer Enzyme transformiert werden, die nur ein aktives Zentrum haben. Wenn eine Krankheit das Ausgangsenzym ändert, werden dann in der Analyse auch alle ersetzenden Enzyme geändert. Es gibt zwei unterschiedliche Betrachtungsweisen, um multifunktionelle Enzyme zu beschreiben. Zum einen kann man die Gesamtreaktionen betrachten und zum anderen die elementaren Reaktionsschritte (Hemireaktionen, Halbreaktionen). Für Enzyme mit zwei oder mehr Funktionen ist es wichtig, nur linear unabhängige Funktionen zu betrachten, weil sonst zyklische elementare Moden auftreten würden, die keine Nettoumwandlung durchführen. Jedoch ist die Wahl der linear unabhängigen Funktionen nicht a priori eindeutig. Wir stellen eine Methode für das Treffen dieser Wahl vor, indem wir die konvexe Basis des Hemireaktions-Systems betrachten. Eine formale Anwendung des Algorithmus für das Berechnen der elementaren Flussmoden (Routen) erbringt das Resultat, dass die Zahl solcher Moden manchmal vom Niveau der Beschreibung abhängt, wenn einige Reaktionen reversibel sind und die Produkte der multifunktionellen Enzyme externe Metabolite sind, oder einige multifunktionelle Enzyme zum Teil die gleichen Stoffwechselprodukte umwandeln. Jedoch kann dieses Problem durch eine geeignete Deutung der Definition der elementaren Moden und die korrekte Wahl der unabhängigen Funktionen der Multifunktionsenzyme gelöst werden. Die Analyse wird durch einige kleinere Beispiele und ein größeres biochemisches Beispiel veranschaulicht, das aus dem Nukleotidmetabolismus stammt und die zwei Arten der Beschreibung für Nukleosiddiphosphokinase und Adenylatekinase vergleicht. Der Nukleotidmetabolismus spielt eine wichtige Rolle in lebenden Organismen und ist gegenüber allen möglichen Störungen in seiner internen Balance sehr empfindlich. Gefährliche Krankheiten können auftreten, wenn einige Enzyme nicht richtig funktionieren. Mit Hilfe des Konzeptes des elementaren Flussmodus erklären wir das Auftreten und den Schweregrad von Krankheiten, die auf Enzymdefizienzen basieren. Wenn ein Enzym vollständig gehemmt wird, werden einige metabolische Wege blockiert. Wenn jedoch einige alternative Wege noch bestehen, ist die Krankheit weniger gefährlich. Unsere Analyse ist darauf gerichtet, alternative Wege, wesentliche Enzyme und solche Enzyme, die immer zusammenarbeiten zu finden. Der letzte Begriff ist auch als "Enzyme subset" bekannt und stellt einen intermediären Schritt im Algorithmus zur Berechnung der elementaren Flussmoden dar. Wir diskutieren bereits bekannte und bisher nur hypothetische Mechanismen einiger Krankheiten (proliferative Krankheiten, Immundefizienzen), die auf Störungen des Nukleotidmetabolismus oder seiner Ausbeutung durch Viren und Parasiten beruhen. Die meisten Strategien, die für das Bekämpfen solcher Krankheiten eingesetzt werden, basieren auf der Unterbrechung des Nukleotidmetabolismus an bestimmten Stellen. Diese Strategien können aber auch zur Akkumulation toxischer Stoffe führen und dadurch Nebenwirkungen hervorrufen. Deswegen hilft ein besseres Verständnis dieses Systems, wirkungsvollere Medikamente zu entwickeln, und eine gute strukturelle Analyse kann viele experimentelle Bemühungen ersparen. Konzepte aus der Theorie der Petri-Netze liefern zusätzliche Werkzeuge für das Modellieren metabolischer Netzwerke. In Kapitel 4 werden die ähnlichkeiten zwischen einigen Konzepten in der traditionellen biochemischen Modellierung und analogen Konzepten aus der Petri-Netztheorie besprochen. Zum Beispiel entspricht die stochiometrische Matrix eines metabolischen Netzwerkes der Inzidenzmatrix des Petri-Netzes. Die Flussmoden und die Erhaltungs-Relationen haben die T-Invarianten beziehungsweise P-Invarianten als Gegenstücke. Wir decken die biologische Bedeutung einiger weiterer Begriffe aus der Theorie der Petri-Netze auf, nämlich "traps", "{siphons", "deadlocks" und "Lebendigkeit". Wir konzentrieren uns auf der topologischen Analyse anstatt auf die Analyse des dynamischen Verhaltens. Die geeignete Behandlung der externen Stoffwechselprodukte wird ebenfalls besprochen. Zur Illustration werden einige einfache theoretische Beispiele vorgestellt. Außerdem werden einige Petri-Netze präsentiert, die konkreten biochemischen Netzen entsprechen, um unsere Resultate zu belegen. Zum Beispiel wird die Rolle der Triosephosphatisomerase (TPI) im Metabolismus von Trypanosoma brucei ausgewertet, indem "traps" und "siphons" ermittelt werden. Alle behandelten Eigenschaften von Petri-Netzen werden anhand eines Systems illustriert, das aus dem Nukleotidmetabolismus stammt. Während viele Bemühungen für das Zerlegen metabolischer Systeme, (elementare Flußmoden, extreme Wege) erfolgt sind, sind bisher unseres Wissens keine Versuche in dieser Richtung für Signalübertragungssysteme unternommen worden. Eine spezielle Eigenschaft von Signalnetzwerken in lebenden Zellen ist, dass Aktivierungen, Hemmungen und biochemische Reaktionen normalerweise gleichzeitig anwesend sind. Selbst wenn sie nicht Reaktionen enthalten, machen Mehrfach-Aktivierungen oder Mehrfach-Hemmungen die Netzwerke in hohem Grade verzweigt. Es ist eine schwierige und sehr zeitraubende Aufgabe, alle Faktoren, die einen Einfluss auf ein gegebenes Ziel haben, ohne eine automatische Methode zu ermitteln. Bereits in Kapitel 1 heben wir die ähnlichkeiten und Unterschiede zwischen den metabolischen und Signal-Netzwerken hervor. In Kapitel 5 errichten wir einen Rahmen und präsentieren einen Algorithmus für die Zerlegung von Signalnetzwerken in kleinere Einheiten, die einfacher zu studieren und zu verstehen sind. Zwei Fälle werden untersucht: ein einfacheres, wenn nur monomolekulare Aktivierungen oder Reaktionen anwesend sind, und ein komplizierterer Fall, wenn die Aktivierungen und die Reaktionen multimolekular sein können. Ihre Beschreibung erfordert unterschiedliche Methoden: klassische Graphen bzw. Petrinetze. Wir besprechen die Probleme, die in unserem Modell wegen des Vorhandenseins von Hemmungen oder von unbekannten Effekten im Netz auftreten. Der vorgeschlagene Algorithmus ermittelt die Faktoren, die zusammenwirken und die Zielsubstanzen, die auf dem gleichen Weg beeinflusst werden. Die Zyklen, die im System auftreten, und mögliche fehlende Reaktionen werden ebenfalls ermittelt . Theoretische Beispiele veranschaulichen unsere Resultate. Anhand der T-Zell-Antigen-Rezeptor-Signalkaskade zeigen wir, wie die Methoden in realen Systemen angewendet werden können. / The living organisms are too complex when considering them as a whole. The present thesis deals with the topological properties of two important parts of living organisms: the metabolic and the regulatory systems. The topological properties are those features that are determined by the network structure. A classification in metabolic and regulatory systems is often used. A signalling system is a special kind of regulatory system. Between metabolic and signalling networks, there are important differences that impose their treatment in different ways. In metabolic pathway analysis, the elementary flux mode concept is already established as a proper tool for identifying the smallest essential routes in biochemical systems. We examine its features and advantages in some particular cases. Firstly, many enzymes operate with low specificity (e.g. nucleoside diphosphokinase, uridine kinase, transketolase, transaldolase), so that various substrates and products can be converted. Also the enzymatic mechanisms are diverse, as we have illustrated with reaction schemes for bifunctional enzymes. Therefore, there are two different approaches to describe multifunctional enzymes (We considered only the case when a certain active site hosts several reactions. The case when the studied enzyme has several such active sites can be transformed into that of several enzymes having only one active site. If a disease alters the initial enzyme, also all substituting enzymes are altered.): in terms of overall reactions and in terms of reactions steps (hemi-reactions, half-reactions). For enzymes with two or more functions, it is important to consider only linearly independent functions, because otherwise cyclic elementary modes would occur which do not perform any net transformation. However, the choice of linearly independent functions is not a priori unique. In Chapter 2, we give a method for making this choice unique by considering the convex basis of the hemi-reactions system. The set of linearly independent functions provided by our algorithm coincides, in the case of transketolase in pentose phosphate pathway, with the set of linearly independent functions mentioned in literature. A formal application of the algorithm for computing elementary flux modes (pathways) yields the result that the number of such modes sometimes depends on the level of description if some reactions are reversible and the products of the multifunctional enzymes are external metabolites or some multifunctional enzymes partly share the same metabolites. However, this problem can be solved by appropriate interpretation of the definition of elementary modes and the correct choice of independent functions of multifunctional enzymes. The analysis is illustrated by a biochemical example taken from nucleotide metabolism, comparing the two ways of description for nucleoside diphosphokinase and adenylate kinase, and by several smaller examples. The nucleotide metabolism plays an important role in living organisms and is very sensitive to any perturbations in its internal balance. Dangerous diseases may occur if some enzymes do not work properly. With the help of elementary flux mode concept, we explain the occurrence and severity of diseases based on enzyme deficiencies. If an enzyme is completely inhibited, some metabolic routes are blocked. If, however, some alternative routes still exist, the disease is less dangerous. In Chapter 3, we focus on finding alternative routes, essential enzymes and enzymes operating together. The latter notion is also known as ,,enzyme subset`` and represents an intermediary step in calculating the elementary flux modes. The known or hypothesised mechanisms of several disorders, occurred due to the malfunctioning of nucleotide metabolism (proliferative diseases, immunodeficiency diseases) or due to its hijacking by viruses and parasites, are given. Most strategies adopted for curing such diseases are based on nucleotide metabolism interruption. Therefore, a better understanding of this system helps developing more effective drugs and a good structural analysis can spare many experimental efforts. Petri net concepts provide additional tools for the modelling of metabolic networks. In Chapter 4, the similarities between the counterparts in traditional biochemical modelling and Petri net theory are discussed. For example, the stoichiometry matrix of a metabolic network corresponds to the incidence matrix of the Petri net. The flux modes and conservation relations have the T-invariants, respectively, P-invariants as counterparts. We reveal the biological meaning of some notions specific to the Petri net framework (traps, siphons, deadlocks, liveness). We focus on the topological analysis rather than on the analysis of the dynamic behaviour. The treatment of external metabolites is discussed. Some simple theoretical examples are presented for illustration. Also the Petri nets corresponding to some biochemical networks are built to support our results. For example, the role of triose phosphate isomerase (TPI) in Trypanosoma brucei metabolism is evaluated by detecting siphons and traps. All Petri net properties treated in above-mentioned chapter (4) are exemplified on a system extracted from nucleotide metabolism. While for decomposing metabolic systems, many efforts have been done (elementary flux modes, convex basis, extreme pathways), for signalling maps, as far as we know, no attempt in this direction has been made. A special characteristic of signalling networks is that activations, inhibitions, and biochemical reactions are normally present in parallel. Even if they do not contain reactions, multi-part activations or inhibitions make them highly branched. To detect all factors that have an influence on a given target, without using an automatic method, is a difficult and very time-consuming effort. Already in Chapter 1 (Backgrounds), we highlight the similarities and differences between metabolic and signalling networks. In Chapter 5, we build a framework and algorithm for decomposing signalling networks in smaller units, which are easier to study and understand. Two cases are investigated: a simpler one, when only monomolecular activations or reactions are present, and a more complex case, when the activations and reactions can be multimolecular. Their description requires different instruments: classical graphs and Petri nets, respectively. We discuss the problems that occur in our model due to the presence of some inhibitions or unknown effects in the network. The algorithm that we propose detects the factors that are acting together and the targets that are affected on the same route. The cycles that occur in the system are also highlighted. We point out possible missing reactions. Theoretical examples illustrate out findings. Using the T cell antigen-receptor signalling cascade, we show how it can be applied to real systems.

Environ vingt milliards d’euros, tel est le coût de la délinquance économique et financière en France. Phénomène proche de la criminalité organisée et pourtant toujours mal défini, délinquance atypique aux caractères spécifiques, elle demeure un espace où seuls quelques initiés parviennent à déjouer les malversations commises par des criminels précurseurs quant à leur modes opératoires. Gangrène du système socio-économique, elle tend à être appréhendée aujourd’hui dans l’hexagone, mais les réformes successives et novatrices ne sont pas synonymes d’une répression adaptée. Si le système judiciaire s’est doté de dispositifs de lutte fondés sur la spécialisation de plusieurs juridictions pénales, l’enquête judiciaire, berceau de toute répression, demeure majoritairement soumise aux règles de procédures du droit commun. Comme l’attestent les retours d’expériences, à une criminalité d’exception s’opposent des pouvoirs d’investigations basiques pourtant susceptibles d’être améliorés par l’adaptation de dispositifs éprouvés. / Twenty billions : that is the cost of financial and economic crime in France. This is close to organised crime, but it still remains an ill-defined phenomenon, an atypical delinquency with specific features, an area where only few initiate persons succeed in twarthing misbehaviours committed by pioneer criminals in regard to the modus operandi they use. Financial and economic crime plagues the social and economic system, and although this tends to be contained in France, successive and innovative reforms haven’t ensured a more appropriate criminal justice response. Judicial system has been provided with specialized penal courts, but judicial inquiry, the cradle of fight against crime, still remains subject to ordinary criminal procedural rules. As feedbacks show, basic investigation powers contrast with exceptional delinquency, whereas they could be improved by the adaptation of the tested investigation devices.

Syfte – Studiens syfte är att utifrån en värdeflödesanalys kartlägga ett råmaterialflöde samt identifiera icke-värdeskapande aktiviteter och föreslå förbättringsförslag. För att besvara syftet har det brutits ned i tre följande frågeställningar: Vilka icke-värdeskapande aktiviteter kan identifieras i flödet? Vad finns det för argument till att åtgärda de upptäckta icke- värdeskapande aktiviteterna Hur kan de upptäckta icke-värdeskapande aktiviteterna åtgärdas för att höja effektiviteten? Metod - Den genomförda studien är en fallstudie vilken bygger på en induktiv ansats med kvantitativa inslag. Den använda metoden är av kvalitativ karaktär då studien grundar sig på intervjuer och tolkning utifrån observationer av den grundläggande datainsamlingen. Datainsamlingen har genomförts utifrån litteraturstudier, intervjuer, observationer och dokumentstudier. För att nå en hög trovärdighet har det vid utformning av intervjufrågor varit viktigt att dessa kunnat kopplats till uppfyllnad av syftet. Detta arbete gjordes för att minimera risken för systematiska fel. Resultat – Studiens resultat bygger på en kartläggning av ett flöde där en nulägesanalys genomfördes för att sedan genomföra en värdeflödesanalys. Utifrån värdeflödesanalysen framgick det att en brist i flödet var höga nivåer av slöserier. Det största identifierade slöseriet var bristande kvalité, främst orsakat av produktion av defekta produkter. Denna brist påverkar vidare stora delar av flödet. De åtgärdsförslag vilka läggs fram i studien är att via en förändring av kulturen på företaget, genomföra standarder och vidare jobba med ständiga förbättringar. Implikationer – Resultatet visar vikten av att arbeta med effektivisering av slöserier vilket i studiens fall leder till bristande kvalitet främst i form av produktion av defekta produkter. Studien har ett praktiskt bidrag till tillverkande företag, genom att ta till sig de presenterade åtgärdsförslagen kan det generera en bättre samsyn på kvalitet i verksamheten. Även ett teoretiskt bidrag ges i form av att ämnet ständigt är under utveckling och behöver ny uppdaterad data. Vidare forskning skulle kunna se över hur man rent tekniskt och psykologiskt implementerar en förändring likt denna. Begränsningar – Resultatet kan vara svårt att generalisera eftersom detta är en studie genomförd som en enfallsdesign. Vidare är det även komplext att undersöka och utveckla en studie vilken visar på hur kvalitet är kopplat till företagskultur. / Purpose – The purpose with this study is to map a raw material value flow analysis and identify non-value-creating activities and propound suggestions for improvement. Method – The study is a case study based on an inductive approach with quantitative elements. The used methods is of a qualitative character since the study is based on interviews and interpretation based on observations of the basic data collection. The data collection has been done through literature studies, interviews, observations and document studies. In order to achieve high credibility, it has been important that the design of interview questions can be linked to fulfillment of the purpose. This work was done to minimize the risk of systematic errors. Findings – The study's results are based on a mapping of a flow where a current analysis was carried out to then later end in a value flow analysis. Based on the value flow analysis, it appeared that a shortage in the flow was high levels of waste. The largest identified waste was a lack of quality, mainly due to the production of defective products. This shortcoming also affects large parts of the flow. The measures proposed in the study are to implement standards through a change in the culture of the company, and to continue to work on continuous improvements. Implications – The result, which shows the importance of working with streamlining waste, which in this case leads to a lack of quality, mainly in the form of production of defective products. The study can be seen as a practical contribution to manufacturing companies, by embracing these proposals for action, it should generate a better consensus on the quality of the business. Also a theoretical contribution where further research could look at how to technically and psychologically implement a change like this. Limitations – It can be difficult to generalize the results as this is a study conducted as a one-case design. Furthermore, it is also complex to investigate and develop a study that shows how quality is linked to corporate culture.

A series of glasshouse and laboratory experiments was carried out to enable comparison of two woody perennial legumes, gorse and broom, with other legumes, nodulated non-legumes and other biological nitrogen fixing systems. Both species had distinct juvenile phases in which broom closely resembled herbaceous species in appearance, but adult plants of both species bore little resemblance to each other or to other legume species. Nodule development was similar to that of other legumes, but mature nodules exhibited structural adaptations to longevity - meristematic activity, a well developed vascular system and numerous cytoplasmic granules in cortical cells. Acetylene reduction and ¹⁵N₂ fixation continued for much longer following excision than has been observed in other legumes. In all experiments, broom nodules exhibited higher rates of acetylene reduction and nitrogen fixation than did gorse nodules. The first detectable product of nitrogen fixation in excised nodules - ammonia - was rapidly incorporated into amide and ∝ amino groups and another unidentified fraction. The principle free amino acid in nodules and sap was asparagine. Its preponderance increased as plants aged. Whole nodulated plants and excised nodules of both species exhibited a relatively low temperature optimum for growth and nitrogen fixation (22°C). They were very sensitive to elevated temperatures. Results indicated that gorse and broom have relatively low light requirements. When aeration was sufficient, combined nitrogen had little effect on growth of nodulated plants. Nodulation in both species was reduced by increasing amounts of combined nitrogen. High levels (100 mg/1) of nitrate and ammonia caused considerable inhibition of nitrogen function. Both species showed large responses to phosphate, but were able to grow and fix nitrogen when supplied with low amounts of phosphate. Boron deficiency reduced nitrogen fixation. Nodulation was increased to compensate for this. Considerable amounts of nitrogen can be contributed to the ecosystem in gorse end broom litter. Direct transfer between gorse or broom and Pinus radiate is likely to be small and may be masked by competition for other nutrients. These findings are discussed with respect to the use of gorse and broom to overcome nitrogen deficiency in reafforestation on the Moutere Gravels, in Nelson, N.Z.

The doctoral dissertation thesis is focused on assessment of information systems and defines the main deficiencies in operation and management of information systems in relation to processes in the department of informatics with partial overlapping into the other parts of the company. The thesis further extends the current view of assessment of information systems in the company and, in accordance with the goal of the work, it defines its own methodology, which defines the specific assessment process and subdivides its contents into individual units. The proposed methodology provides an overview of the deficiencies and possible measures in operation and management of information systems. Qualitative verification of methodology in small, medium and large companies using case studies form a part of the thesis as well.

South African affirmative action law in the workplace is in its infancy. Yet some concepts in this context have already proven to be unclear or in need of interpretation, or are lacking. This thesis focuses on the beneficiaries of affirmative action in employment law. The Employment Equity Act (EEA) creates `designated groups' ─ black people, women and people with disabilities ─ as the beneficiaries of affirmative action. It lays down two requirements for beneficiaries of affirmative action which are investigated: (a) beneficiaries must be from the designated groups - in this regard, the question that arises is whether, having been categorised as disadvantaged, persons are presumed to be de facto disadvantaged and entitled to benefit from affirmative action, or whether further evidence of actual past disadvantage is required; and (b) beneficiaries must be `suitably qualified'. In addition, citizenship as a third requirement for beneficiaries of affirmative action has been mooted in case law. This is evaluated against modern interpretation theory, the Constitution and discrimination law. Against the background of a comparative investigation of the position in the US and Canada, and under international law, specific findings and recommendations are made in respect of South African affirmative action law. These relate to the interpretation of the concept `disadvantage', to a pragmatic and contextualised approach to the notion `degrees of disadvantage', to the recognition of the concept `multiple disadvantage', to the clarification of the meaning and application of the concept `suitably qualified' in a code of good practice, and to a policy decision by government to ensure that affirmative action measures apply mainly to South African citizens who otherwise qualify to benefit. To this end, certain amendments to the EEA, its regulations and codes of good practice are proposed with the aim of ensuring that affirmative action measures in fact benefit those intended by the EEA. Some projections are made to indicate the way forward for affirmative action in South Africa. / Jurisprudence / LL.D.
