The depletion of a great many conventional fish stocks is urgent testimony for fisheries management to evaluate risk and uncertainty in an interpretable manner. We propose a novel decision based approach to time-series analysis that explores the spectrum of alternative population trajectories, each of which can be formulated as hypotheses about the state of the fishery. In the first chapter, we evaluate the ability of different regions of the surplus production state space to describe the true state of three North American fisheries: Pacific cod, porbeagle shark and yellowtail flounder. We consider how environmental variability and life history traits may alter our assumptions about population productivity, and we lay the foundation for a decision based age-structured analysis. In the second chapter, the approach is extended further into the ecological realm by considering how community interactions between Atlantic cod and harp seals can be represented in state space. Our results indicate that since the fishing moratorium in 1992, harp seals have potentially lowered cod productivity, preventing their recovery.

This thesis is a critical examination of the history of philosophies governing public education in the United States. The first half, chapters one through six, outlines American conceptions of the role of the school in relation to the state and to democracy. The second half is an account of critical progressive philosophies that have challenged the American status-quo since the independence. The main argument that I propose here is that the creation of an education system in America has followed the philosophies of federalism and private democracy. These philosophies are economically centered and define the citizen in economic terms. Progressive educators have long questioned this definition and seek to redefine citizenship to describe participatory democracy, and communication based on experience and an ethic of care.

Social media are increasingly becoming platforms of choice for communication among individuals and groups of the public, and hence organisations are interested in engaging with communities and the public through this form of media to gain intelligence from such engagements to support their decision making processes. Yet, organisations are missing on realising the potential value from using social media for this type of interaction and engagement, while paucity in research addressing practical ways to use social media communication in supporting decision making still persists. This research investigates and proposes a practical framework for using social media – specifically Twitter – as a communications instrument to support the decision making process in police organisations. The research design is based on developing and evaluating a proof of concept representing engagements between the United Arab Emirates (UAE) police as a case study of police organisations with communities and members of the public in the UAE. The proof of concept is designed based on comparing and contrasting current practices by the UAE police with models, trends, and practices discussed in related literature. The research uses the Grounded Theory methodology to guide sampling, data collection, and analysis. The contribution of the research is to both theory and practice. The research addresses a gap in the body of knowledge for a framework that guides the development of models, policies, and practices for the use of social media as a communication instrument to support decision making in governmental organisations, specifically the police. In addition, the framework offers practical insights to policy makers into using different social media to engage with the public in communication, interactions, and knowledge sharing, with the aim of supporting decision making.

The aim of this study was to analyse the role of the registered nurse in the management of pro re nata (PRN) medication in a care home (nursing) for older people. Studying PRN medication provides insights into the role of the nurse in care homes (nursing) who act as assessor, decision maker and evaluator in residents' care. It also provides a lens by which to explore how residents and their carers interact and participate in day-to-day care decisions about residents' health. The case study draws on ethnography. It is a multi-method study, using documentary and medication reviews, observations and interviews to answer the research questions. Thirty-four residents were recruited to the study and 60 care home staff. Findings showed that 88.2% of residents (n=30) were prescribed PRN medication and that all residents were on a minimum of 1 and a maximum of 7 medication. During each 28-day MAR sheet period between 35 and 44 PRN prescriptions were written. They contributed 12.7% of all medication prescribed, accounting for between 1.2 and 1.5 medication per resident. Nurses were found to administer PRN medication, but a finding of this study was that this activity could be delegated to carers who were identifying resident needs. There was some evidence of resident engagement but this was often a three-way process between resident, GP and family or resident, carer and nurse. A percentage of medication that could have been PRN were routinely prescribed. Observations also identified that nurses would decide not to administer routine medication in certain circumstances and that this was directly related to their assessment of the resident. The process of medication management was dominated by the regulations and governance processes of the care home. Observations and interviews found that care home staff recognised and affirmed residents' pain but did not take action for analgesia to be administered. They were familiar with the use of pain assessment tools for older people living with dementia and had received training in dementia care. Many of the staff were also able to interpret signs and symptoms of a resident's distress. Nevertheless, their preoccupation with meeting internal and external regulator standards was a barrier to addressing residents' needs. This is the first study that has looked at an aspect of medication management to understand how nurses and care home staff work for and with residents to moderate and address their health care needs. It suggests that additional training in aspects of medication management and resident assessment may not be able to address deeper seated issues of autonomy and how the nursing role is understood and enacted in care home settings.

M.Ed. / This study forms part of a greater ongoing research project concerning teacher competence and its assesment. The project focuses on researching teacher opinion on teacher competences identified by the initial research. The following areas of teacher competence are being researched : The learning environment Professional commitment Order and discipline Educational foundation Teacher reflection Co-operative ability Effectiveness Leadership This dissertation is part of the research undertaken regarding order and discipline and its role in teacher competence. An intensive research of the literature has given rise to a conceptualisation that consists of the following five aspects, namely : values; rules; human relationships; management of classroom behaviour; and teaching practices. This research essay focuses on classroom management behaviour as an aspect of order and discipline : implication for the management of teacher competence. Having orientated the reader to the particular field of research, the motivation and background of the problem will now be discussed.

The business environment of today is characterised by great risks for organisations as well as for individuals. New principles and ways of working that differ significantly from what was done even as little as a decade ago are required. To keep to traditional stances in the corporate environment may mean that existing competitive advantages may not be enough anymore to ensure success. This also applies to the financial services sector where there is currently a clear shift from a product focus to a client focus. In the light of changes taking place in the financial services sector, it is also necessary to think differently about the mediators (brokers) delivering related services since the delivery channels have also changed due to technological development. Competitive advantages lie in a client and market focus rather than a product focus, and a process focus rather than a functional focus. The client’s voice must be heard and it is possible that a successful person in this focus is different from a successful person in the old focus. For the sake of quality in service delivery and alignment in the same direction, it is necessary for management to have a shared mental model when looking at staff decisions concerning brokers. They must also be aware of their own thoughts about staff within the changing focus and they must realise the impact this can have on their decisions. The main objective of this study is to determine whether the managers under investigation have a shared mental model in terms of success criteria for brokers. In order to do this, it is necessary to first investigate the concepts mental model and shared mental model and the impact they may have in an organisational environment. The Repertory Grid technique was used for data collection. As a result of the wide variety of Repertory Grid techniques, together with the various ways of application, it is essential to be familiar with the techniques and modes of application in order to choose the most suitable technique and application method for a specific study. Kelly’s Personal Construct theory contains the assumptions underlying this technique and it is important for a researcher to be aware of these regardless of whether this is the theory s/he will be using since the underlying assumptions will definitely have an influence on the interpretation of the results. The data was presented as a qualitative description of each manager’s mental model in terms of the successful broker as well as a short description of the person’s construction system regarding success in their business environment. Conclusions were made from a synthesis of the results regarding the extent to which there could be referred to a shared mental model and its possible impact on decisions and efficiency in the work and business environment. The results confirmed that the objectives of this research project were met. It emerged that this management team does not effectively share a mental model and that this may impact negatively on their business decisions. Recommendations were made regarding the change or establishment of a client-focused mental model. Suggestions for future research regarding broker efficiency were also made. / Thesis (MA (Research Psychology))--University of Pretoria, 2002. / Psychology / unrestricted

Thesis (LLM (Private Law))--University of Stellenbosch, 2010. / ENGLISH ABSTRACT: The most important innovations of the revised German Wohnunungseigentumsgesetz which came into force on 1 July of 2007, concern the possiblity to amend parts of the constitution of the scheme (Gemeinschaftsordnung) by majority instead of unanimous resolution; the extension of the decision-making competence of sectional owners; the easier and more appropriate distinction between maintenance of and luxurious and non-luxurious improvements to the common property; the recognition that the body corporate has legal capacity to act in certain circumstances; the increase in the functions and powers of the professional manager (Verwalter); and the replacement of the procedure for non-contentious matters for the settlement of disputes by the ordinary civil court procedure. These predominantly valuable innovations raise the question in how far South African law could benefit from these amendments, and whether they could be used as a model for solving some of the unsatisfactory aspects of the South African sectional title law. The revised Wohnungseigentumsgesetz now allows apartment owners to amend more provisions of the constitution by majority resolution. The harsh unanimity principle is in many contexts replaced by the majority principle and individual apartment owners are allowed to request an amendment of certain provisions of the constitution for important reasons. The Sectional Titles Act and the model management and conduct rules regulate the relationship between sectional owners in South Africa. Both the developer and the body corporate have the authority to supplement or amend the existing model rules by special rules. However, in comparison with the revised Wohnungseigentumsgesetz the management and conduct rules can only be amended by a unanimous or special resolution for management and conduct rules respectively and an individual owner is not allowed to request an amendment of a model rule on account of the unfair consequences suffered by him or her. An important advantage of the revised Wohnungseigentumsgesetz in comparison with section 32(4) of the Sectional Titles Act is furthermore that no written consent is required from the sectional owner who is adversely affected by an amendment of certain aspects of the participation quota. This requirement causes many problems. First, the circumstances in which an owner can be considered adversely affected have not been judicially determined. Second, the South African requirement is out of step with modern conditions, which witness the number of larger schemes increasing, because it allows one owner to block objectively necessary resolutions of the body corporate. The provision requiring the written consent of the adversely affected owner should therfore be repealed. The same applies to the general requirements for carrying out maintenance of and improvements to the common property. On closer analysis it becomes clear that the management rules contain no criteria to distinguish between maintenance and improvement measures or between luxurious and non-luxurious improvements. In final analysis these distinctions seem to depend on subjective rather than on objective criteria. By contrast the revised Wohnungseigentumsgesetz contains a clear objective distinction between the four categories of improvements to the common property. / GERMAN ABSTRACT: Seit dem 1. Juli 2007 gilt in Deutschland ein novelliertes Wohnungseigentumsgesetz. Die wichtigsten Neuerungen betreffen die Ermöglichung von Änderungen der Gemeinschaftsordnung nicht nur durch einstimmigen Beschluss der Wohnungseigentümer, die Erweiterung der Beschlusskompetenzen der Wohnungseigentümer, die Erleichterung der Durchführung baulicher Maßnahmen, die Gestaltung der Teilrechtsfähigkeit der Eigentümergemeinschaft und die Festlegung der erweiterten Rechte und Pflichten des Verwalters sowie die Überleitung des Verfahrens der freiwilligen Gerichtsbarkeit in die Zivilprozessordnung. Die überwiegende Zahl der grundsätzlich zu begrüßenden Neuregelungen gibt auch für das südafrikanische Recht wertvolle Denkanstöße zu der Frage, ob eine Novellierung des Sectional Titles Act im Sinne der Neuregelungen des WEG eine Möglichkeit wäre, bestehende „Ungereimtheiten“ und Probleme zwischen den Wohnungseigentümern und im Wohnungseigentumskomplex in Südafrika besser lösen zu können. Im neuen novellierten WEG sind mehr als bislang Mehrheitsentscheidungen der Wohnungseigentümer zulässig. Statt des starren Einstimmigkeitsprinzips gilt nun oftmals das Mehrheitsprinzip. Zudem ist es auch dem einzelnen Wohnungseigentümer möglich, eine Änderung einer Vereinbarung zu verlangen, sofern ein Festhalten an einer geltenden Regelung aus schwerwiegenden Gründen unter Berücksichtigung aller Umstände des Einzelfalles, unbillig erscheint. Gesetzliche Regelungen, welche das Gemeinschaftsverhältnis in Südafrika ordnen, sind im Sectional Titles Act selbst und in den management und conduct rules der Annexure 8 und 9 des Sectional Titles Act enthalten. Zudem hat sowohl der developer als auch die Wohnungseigentümergemeinschaft (body corporate) die Befugnis, die Rechte, Pflichten und Nutzungsrechte der Wohnungseigentümer in sogenannten „special rules“ selbst festzulegen. Im Vergleich zu den Regelungen des novellierten WEG ist es für Wohnungseigentümer in Südafrika jedoch schwerer, eine Änderung solcher Regelungen herbeizuführen. Wollen die Wohnungseigentümer von den Regelungen der management oder conduct Rules abweichen, können sie dies bezüglich der management rules nur durch einheitlichen Beschluss (resolution) und hinsichtlich der conduct rules mittels eines Beschlusses mit 75%er Mehrheit (special resolution). Ein individueller Anspruch des einzelnen Wohnungseigentümers auf Änderung, Ergänzung oder Ersetzung der rules bei Unbilligkeit besteht nicht. Ein gewichtiger Vorteil der Neuregelung des § 16 Abs. 3 WEG im Vergleich zu Artikel 32(4) des Sectional Titles Act ist zudem, dass es in Deutschland keiner schriftlichen Zustimmung des von der Entscheidung negativ betroffenen Wohnungseigentümers bedarf. Eine Änderung der participation quota hinsichtlich des Kostenverteilungsschlüssels ist nur möglich, wenn ein von der Entscheidung negativ betroffener Wohnungseigentümer seine schriftliche Zustimmung erteilt. Wann eine solche negative Betroffenheit („adversely affected“) letztlich vorliegt, ist zum einen nicht abschließend geklärt. Zum anderen ist gerade unter der Prämisse immer größerer werdender sectional titles schemes nicht mehr zeitgemäß, einem einzelnen Wohnungseigentümer die Möglichkeit zu geben, objektiv notwendige Entscheidungen der body corporate zu blockieren. Das Erfordernis der Zustimmungsbedürftigkeit eines negativ betroffenen Wohnungseigentümers sollte daher aufgegeben werden. Gleiches gilt für die generelle Zulässigkeit von baulichen Veränderungen. Bei genauerer Analyse des südafrikanischen Rechts wird zudem klar, dass in den Management Rules nicht definiert ist, was unter Verbesserungen, d.h. unter „improvements to the common property“ zu verstehen ist oder wie im Einzelfall zwischen luxuriösen und nicht-luxuriösen Aufwendungen zu unterscheiden ist, da es letztlich von der subjektiven Betrachtungsweise Einzelner abhängt. Das novellierte WEG enthält im Vergleich dazu eine klarere objektive Begriffsabgrenzung der vier Kategorien baulicher Maßnahmen. / AFRIKAANSE OPSOMMING: Die belangrikste veranderings aangebring deur die wysiging van die Duitse Wohnunungseigentumsgesetz wat op 1Julie 2007 in werking getree het, is die volgende: die wysiging van die reëls van die skema (Gemeinschaftsordnung) deur middel van ‘n meerderheidsbesluit in plaas van ‘n eenparige besluit; die uitbreiding van die besluitnemingsbevoegdhede van deeleienaars, die helder en meer gepaste vereistes vir die aanbring van verbeterings aan die gemeenskaplike eiendom, die erkenning van die regsbevoegdheid van die regspersoon in sekere gevalle, die uitbreiding van die bevoegdhede van die professionele bestuurder en die vervanging van die informele geskilbeslegtingsprosedure deur die gewone hofprosedure. Hierdie veranderinge laat die vraag ontstaan in hoeverre die Suid-Afrikaanse reg voordeel kan trek uit hierdie wysigings en in hoeverre die veranderings as model kan dien vir wysiging van onbevredigende aspekte van die Wet op Deeltitels. Die gewysigde Wohnunungseigentumsgesetz laat deeleienaars tans toe om meer bepalings van die model reëls deur meerderheidsbesluit te verander. Die streng eenparigheidsbeginsel word in meerdere verbande deur die meerderheidsbeginsel vervang en deeleienaars word in sekere gevalle selfs toegelaat om aansoek te doen vir die wysiging van sommige bepalings op grond van ‘n geldige rede. Die Wet op Deeltitels en die model bestuurs- en gedragsreëls reguleer die regsverhouding tussen deeleienaars. In teenstelling met die gewysidge Duitse wet kan die die regspersoon die bestuursreëls slegs deur middel van ‘n eenparige besluit en die gedragsreëls deur middel van ‘n spesiale besluit verander en ‘n deeleienaar word nie toegelaat om ‘n verandering van die reëls aan te vra op grond van onregverdige benadeling nie. ‘n Belangrike voordeel van die gewysigde Duitse wet in vergelyking met artikel 32(4) van die Wet op Deeltitels is verder dat die skriftelike toestemming van ‘n deeleienaar wat deur die wysiging van sekere aspekte van die deelnemingkwota benadeel word, nie verkry hoef te word nie. Dit is ‘n groot verbetering. Eerstens is dit moeilik om te bepaal in watter omstandighede ‘n deeleienaar se regte deur die wysiging van die deelnemingskwota benadeel word. Tweedens is die Suid-Afrikaanse bepaling uit pas met moderne ontwikkelings waar ‘n deeleienaar in groot deeltitleontwikkelings toegelaat word om objektief redelike besluite van die regspersoon te blokkeer. Hierdie bepaling van die Wet op Deeltitels moet dus herroep word. Dieselfde geld vir die vereistes met betrekking tot die onderhoud van en verbeterings aan die gemeenskaplike eiendom in die Suid-Afrikaanse wetgewing. Op die keper beskou bevat die bestuursreëls geen geskikte riglyne om tussen die onderhoud van, en luukse en nieluukse verbeterings aan die gemeenskaplike eiendom te onderskei nie. Die onderskeiding berus oënskynlik op subjektiewe eerder as objektiewe oorwegings. Daarenteen bevat die gewysigde Duitse Wet helder, objektiewe kriteria om onderhoud en vier soorte verbeterings aan die gemeenskaplike eiendom te onderskei.
