Part I examines the global rise of both public and private debt and its recent manifestations in the US housing bubble and the financial panic of 2007-8. A review of the most popular theories of the debt crisis is provided, including an explication of securitized banking and economic theory. The underlying condition of increasing ecological and energetic scarcity is accorded central significance in the broad trajectory of world growth and debt, Part II explicates systems theories of social order and the social significance of markets. The theories of Niklas Luhmann, Talcott Parsons, Mario Bunge, Anthony Giddens, and Jürgen Habermas are evaluated with respect to their theories of social order and crisis. A central finding is that, although declining rates of exergy production inhibit the global economic recovery as measured by conventional economic tools, this fact is not likely to be widely recognized. A central theme of Part II is how social systems handle uncertainty, risk, and to what extent complex social systems can be regulated normatively by the public sphere. As global society becomes increasingly interconnected and dependent upon the depletion of material and energy resources, the communication channels that facilitate the self-understanding of modern society at the same time proliferate, becoming increasingly disconnected and self-referential. Luhmann’s systems theory is used to explain why collective recognition and action is at once rendered more necessary and increasingly unlikely given the complexity of global society that Earth’s terrestrial stock of nonrenewable energy resources has engendered.

The present dissertation studies specific issues related to the coordination of a set of "agents" evolving on a nonlinear manifold, more particularly a homogeneous manifold or a Lie group. The viewpoint is somewhere between control algorithm design and system analysis, as algorithms are derived from simple principles --- often retrieving existing models --- to highlight specific behaviors. With a fair amount of approximation, the objective of the dissertation can be summarized by the following question: Given a swarm of identical agents evolving on a nonlinear, nonconvex configuration space with high symmetry, how can you define specific collective behavior, and how can you design individual agent control laws to get a collective behavior, without introducing hierarchy nor external reference points that would break the symmetry of the configuration space? Maintaining the basic symmetries of the coordination problem lies at the heart of the contributions. The main focus is on the global geometric invariance of the configuration space. This contrasts with most existing work on coordination, where either the agents evolve on vector spaces --- which, to some extent, can cover local behavior on manifolds --- or coordination is coupled to external reference tracking such that the reference can serve as a beacon around which the geometry is distorted towards vector space-like properties. A second, more standard symmetry is to treat all agents identically. Another basic ingredient of the coordination problem that has important implications in this dissertation is the reduced agent interconnectivity: each agent only gets information from a limited set of other agents, which can be varying. In order to focus on issues related to geometry / symmetry and reduced interconnectivity, individual agent dynamics are drastically simplified to simple integrators. This is justified at a "planning" level. Making the step towards realistic dynamics is illustrated for the specific case of rigid body attitude synchronization. The main contributions of this dissertation are * I. an extensive study of synchronization on the circle, (a) highlighting difficulties encountered for coordination and (b) proposing simple strategies to overcome these difficulties; * II. (a) a geometric definition and related control law for "consensus" configurations on compact homogeneous manifolds, of which synchronization --- all agents at the same point --- is a special case, and (b) control laws to (almost) globally reach synchronization and "balancing", its opposite, under general interconnectivity conditions; * III. several propositions for rigid body attitude synchronization under mechanical dynamics; * IV. a geometric framework for "coordinated motion" on Lie groups, (a) giving a geometric definition of coordinated motion and investigating its implications, and (b) providing systematic methods to design control laws for coordinated motion. Examples treated for illustration of the theoretical concepts are the circle S^1 (sometimes the sphere S^n), the rotation group SO(n), the rigid-body motion groups SE(2) and SE(3) and the Grassmann manifolds Grass(p,n). The developments in this dissertation remain at a rather theoretical level; potential applications are briefly discussed.

The prime objective of a client in a building project is to attain a successful project, a project that has been properly planned, designed and constructed in accordance with plans and specifications, and completed within time and cost originally anticipated. However the success of a building project depends on a number of variables one of them is the way the building team approach conflicts facing the project. This study examines the causes and management approaches of conflicts in building projects in Tanzania. The main objective of the study is to identify issues/areas on which conflicts occur, factors causing them and how conflicts are managed in building projects in Tanzania. As a means to achieve the above objective, the study was structured into two main parts; the first part aimed at mapping up the nature of conflicts in building projects in Tanzania by establishing critical symptoms of conflicts, factors causing them and the approaches used in resolving the conflicts. This was done through literature review, interviews and questionnaire survey. The second part aimed at in-depth study of conflicts from their root cause, how they develop/progress and how they are managed in a real building project setting. Four case studies of building projects were studied for this part. The study found that factors causing conflicts are in several forms. There are those related to the nature of contracts, where the contracts are unclear and ambiguous they give room for contracting parties to develop opportunistic behaviour when post adjustments are needed. There are those factors which are related to role functions when the parties fail to perform as expected. As such the study confirmed that contractual incompleteness and consequent post contract adjustments and opportunistic behaviour of some project participants are root causes of conflicts in building projects in Tanzania. However, the study established that there are sufficient mechanisms to deal with conflicts in the standard forms of building contracts used and when the provisions are against the interests of the parties, the parties resort to amicable resolution approaches. Notwithstanding the availability of mechanisms in the standard forms of contracts to deal with conflicts, the study proposes the framework as a strategy that could reduce effectively the occurrences of conflicts in building projects. / QC 20110223

Systems thinking. Systems theory. The systems approach. All these concepts have in various guises been claimed as central to logistics management, since its dawning in the mid twentieth century. Such claims are the starting point of this dissertation, the purpose of which is to contribute to an increased understanding of systems thinking in logistics management research, both present and for future advances. The primary unit of analysis in this dissertation is thus logistics management research. The purpose is pursued through a strategy of triangulation of research approaches, via two research objectives: To describe the nature of systems thinking in logistics management research. To explore the merits for logistics management research of an interpretive approach to actors’ systems thinking. The term systems thinking in this dissertation denotes any somewhat ‘organised’ bodies of thought with aspirations to be ‘holistic’ in the sense of aiming for comprehensiveness. This part relates mostly to the systems part of the term. With regard to the other part, systems thinking is also regarded as a term that encompasses thinking about, and in terms of, systems; either that of researchers or that of actors in logistics practices. Systems thinking can sometimes be theorised on in such a way that it seems fair to label it as systems theory. Another term that is also frequently employed is systems approach. This denotes any approach to intervene in and/or conduct research on enterprises, with a holistic ambition. Such approaches can or cannot be informed by systems theory. By approach is meant the fundamental assumptions of the effort, such as ontological and epistemological positions, views on human nature, and methodologies. This dissertation employs an approach informed by a strand of systems theory labelled Critical Systems Thinking (CST). This builds on a pluralist strategy, which entails an awareness of the strengths and weaknesses of all types of systems approaches, and thus strives towards putting them to work under such circumstances in which they are best suited. The first objective is pursued by means of a combined inductive-deductive approach presented mainly through two peer-reviewed, published journal articles. The first is an extensive literature review of academic publications in logistics management; the second is a survey of logistics management academics. Results show that the systems thinking within the discipline most often is not informed by systems theory, and is oriented towards a narrow section of the available systems approaches. This is an approach that builds on an objective world-view (realist ontology), and which seeks knowledge in terms of different kinds of law-like regularities. There are variations to the kinds of knowledge that are sought, in the sense that some search for deeper, underlying generative mechanisms (structuralist epistemology), some seek causal relationships among observable phenomena (positivist epistemology). The common view on human nature is determinist, and methodologies are often quantitative. It is concluded that logistics management employs a functionalist systems approach, which implicitly assumes homogeneity in actors’ systems thinking in mutual contexts (i.e. shared logistics practices). The second objective is pursued by adopting an interpretive systems approach, thus embracing a nominalist ontology and interpretivist epistemology, in order to explore what benefits such a perspective can lend to logistics management. Informed by the pluralist commitment of CST, theoretical constructs and methods grounded in cognitive psychology are employed to study logistics management practitioners’ systems thinking through cognitive mapping. If this reveals heterogeneities in systems thinking among actors of a mutual context, in which a high degree of homogeneity can be expected, the rationale is that the dominant homogeneity assumption is insufficient. The study, presented through an unpublished working paper, concludes that actors’ systems thinking can differ in ways that render the assumptions of the functionalist systems approach inadequate. More thought, debate, and research on an interpretive systems approach within logistics management is called for. With constant expansions in the scope of ambition for logistics management in mind – towards larger enterprise systems in the spirit of supply chain management, towards more goals for enterprises than the traditional financial ones, and towards new application areas (e.g. healthcare) – it is recognised that more and more actors become stakeholders in the practices that logistics management research seeks to incorporate within its domain of normative ambitions. This leads to an expanding scope of voices that ought to be heard in order to legitimise efforts to improve logistics management practices. This in turn motivates that we should seek to accommodate not only interpretive systems approaches, but also emancipatory, in order to ensure normative prescriptions that are legitimate from the perspectives of as many stakeholders as possible, not only from the common a priori efficiency perspectives of functionalist logistics management research.

<p>The aims of the study were to: (1) explore the education support services required by three learners who were integrated into the mainstream, (2) determine the level of support required by these learners to function maximally in the mainstream, (3) specifically explore the socioemotional ability of these learners to adjust to the mainstream setting. Three cases were explored within an eco-systemic approach. Each case consisted of a learner with a physical disability, the learner&rsquo / s mother and the educator/s who first taught the learner at the mainstream school. Interviews were conducted with all of the participants and subsequently transcribed verbatim. Thematic analysis was then conducted to extract themes from the transcriptions.</p>

<p>This research study employs a strengths perspective. This means that, instead of the traditional deficits or pathology-based approach of focusing on weaknesses, the focus is on positive outcomes. Fortitude, more specifically, is the strength gained from appraising oneself, one&rsquo / s family, and one&rsquo / s social support, in a positive manner. This strength equips people to cope successfully in stressful situations. Fortitude as a construct in the strengths perspective promises to give insight into student success because it takes more than one level of analysis into account. The current research study investigates whether there is a link between fortitude and academic achievement in first year students at the University of the Western Cape.</p>

<p>Violence is considered to be one of the most critical and threatening global problems plaguing the world today, leaving a trail of devastating consequences to societies, economies, cultures, families and individuals (Desjarlais &amp / Kleinman, 1997). Adolescents who grow up in a context of violence learn distorted ways of thinking, acting, living and interacting. Aggressive tendencies and violent behaviour become internalised and adopted as acceptable ways to resolve conflict situations. Chronic, continuous exposure to violence results in physical, psychological and emotional disturbances, such as depression, anxiety, lowered self-confidence, sleep disturbances, decreased attention and concentration spans. This study addressed the form of violence known as community violence, i.e. violence that children experience within their communities (either as witnesses or as victims). This study investigated the effects of this negative environmental experience and investigated potential mediating and moderating variables that could influence the harmful effects of such experiences. The variables considered as mediating and/or moderating variables were social support and self-esteem. The theoretical framework adopted for this study was Bronfennbrenner&rsquo / s Bioecological Systems theory.</p>
