The principal aim of the study which was conducted between May 1995 and May 1997 was to collect and analyze information that would be considered vital to any future management actions that may be applied to the deer living in the wild in the Bali Barat National Park ecosystem in Indonesia. The systems approach used sought to analyze the complex interactions between the soil, plant, animal and human activity subsystems. In particular, interaction between Rusa deer and Muntjac deer was compared where possible, although the principal focus of the study was on the population of Muntjac deer. The soils in habitats frequented by deer in Bali Barat National Park were found to be of relatively low fertility status. Chemical analysis of the soil revealed that all of the mineral element contents considered in this study were in the lowest range for soils, in general. During this study the population of Muntjac deer in the Bali Barat National Park was submitted to phylogenetic analysis to determine whether the Bali population is distinct. Preliminary results indicate that these deer are apart of a diverse, but monophyletic group of Muntiacus Muntjac. The potential unique status of Muntjac deer in Bali Barat National Park, and the need to preserve them as part of the natural resource base that constitutes the Indonesian archipelago increased the importance of this study of the ecosystem and social system surrounding Bali Barat National Park. / Doctor of Philosophy (PhD)

Bakgrunden till studien, som inleddes 1991, var en bild av en alltför lång ledtid för ekonomisk information till ledningspersoner i svenska storföretag. Detta gällde speciellt med hänsyn till vad som var tekniskt möjligt att åstadkomma. Resultaten bekräftar i princip denna bild, men de identifierade orsakerna är långt ifrån bara tekniska. Studien kartlägger faktorer som påverkar ledtiden för månatliga ekonomiska rapporter och diskuterar betydelsen av ekonomiska rapporter i svenska storföretag. Dessutom beskrivs storföretagens rutiner vid framställningen av rapporterna, t ex vad som rapporteras och när det sker. Till detta kommer ledningens åsikter om ledtiderna. Studien baseras på intervjuer med representanter för styrelse, ledningspersoner, koncernstab, fristående och en enkätundersökning till Sveriges 200 största företag. / Diss.

The present environmental concerns and the rising human requirement for solutions with better comfort and lower costs have resulted in an increased awareness for the energy use in the built environment. Technical advances in building structural systems and materials, heating and other comfort-providing systems and controlling strategies all lead to the integration of building technology with the function of buildings and the aesthetics. Therefore, in the process of improving the performance of energy systems and increasing the energy efficiency, integrated system approaches are of high importance. Performing the necessary energy analysis before any construction-installation occurs can help designers and decision makers reach guided solutions. Hence, a broad range of calculation tools for evaluating the operation of energy systems and the controls in buildings have been developed the latest years with different levels of complexity and angles of focus. However, research and development regarding holistic energy system designs and techniques are in their infancy. The standard tactic has been to isolate system parts, study them as stand-alone sub-systems and focus on optimising components or processes of a complex function. In the present study, it is demonstrated the necessity for uniting energy engineers, architects, installers and technicians regarding decision making upon the energy use for heating, ventilation and air-conditioning (HVAC) in the built environment. Systems approach has been employed for studying the research issue that is presented in the current thesis. An extended part of this treatise has been devoted to systems thinking in practice. The thesis demonstrates systematic methods of modelling and analysing certain, integrated, domestic, HVAC applications. The reference system boundaries enclose the building as a construction and as a dynamic function, a comfort-providing system based on a heat pump, a low-temperature hydronic heat distribution system and controls in a residential application. Obviously, these are not the only components met in a hydronic heating system. Numerous pieces of equipment, as piping, circulating pumps, expansion tanks, zone valves, relief valves and other essential elements are needed to make a safe and functional heating system. However, this study focuses on the analysis of the chosen reference system. Several models have been developed in the computational tools of TRNSYS and EES. These tools have been employed because they allow co-solving, hence the integrated system as well as the interaction between the different parts of the system can be studied. The foremost result of this study is that approaching the system as a whole provides a better picture of the operation of every system component and the interaction between them. Explanations are given for the parameters that have a significant impact on the system’s performance. The thesis shows the importance of factors that are not easy to predict, as well as the difference in the building’s behaviour under fast changing thermal loads when the incorporated thermal mass is altered. Finally, implementing sophisticated controls for reducing the energy costs without compromising thermal comfort is vital. / QC 20101008

After the introduction of the term,  sustainable development, a variety of  academicians from different disciplines tried to conceptualize it in their own way, drawing on these views, many different degrees but with similar titles have been established in many universities all around the world. Masters  program in  Sustainable Development  (MSD) at Uppsala University and the Swedish University of Agricultural Sciences (SLU) is one the most recent ones. Before starting this study, it was investigated that the expectations of the different actors in this program are not fulfilled completely. Presence of many different ideas and perspectives in addition to the high number of actors involved in the situation made the situation too complex to be fixed easily. Therefore, the Soft Systems Methodology (SSM), as an appropriate approach for improving complex problematic situations,  is  used to reform the organization of  the  MSD in coming years. The process of identifying the  challenges of this program and then  improving some of them in  practice  are described in this thesis. Alongside the  action phase, the applications of Systems Approach in transformation of Education for Sustainable Development (ESD) are explored.  It is investigated that three levels of learning, i.e. basic, meta-  and epistemic learning, and accordingly three levels of organizational change, i.e. the first, second and third order, need to be recognized, if an ESD program is to be different from the unsustainable trends of education.

Ecotourism from its genesis and founding theories has been set out to conserve and preserve the environment through sustainable operation that includes surrounding communities in efforts to reduce their poverty levels. Over the years ecotourism has been hypothesized to have departed from this ideal with several researchers, through social, qualitative analyses, have said that these non-sustainable ecotourism operations are simply due to poor management. This work sought to test this central hypothesis as a first approach to quantitatively linking ecotourism activities to management with surface water quality as the key indicator of sustainable ecotourism as a complex system through systems thinking. This pilot work was done by the use of two study sites in the Caribbean: Iwokrama, Guyana and Greencastle, Jamaica. From General Systems Theory, before systems dynamics can be applied there is a need to first observe components of the system in a reductionist view. This approach had to be taken also since the required data inputs for the systems approach were not available, as is the norm throughout the Caribbean. Thus by creating simple, easy-touse and transferrable sustainability indicator based reductionist-type assessment tools relevant data on ecotourism activities, management and water quality can be obtained in the future and acts as a start to understanding the true systems dynamics among these three entities. The creation of these quantitative reductionist tools utilized social surveying onsite, target plots, sustainability indicators and Social Network Analysis. Tools created were tested through what-if scenarios, with sensitivity analyses, and determined to be able to respond to societal, environmental and economic changes. The basic findings of these reductionist tools were used to establish and initial pathway for quantification inclusive of a framework in STELLA® for the numerical linking of ecotourism management, water quality and sustainability indicators in the Caribbean. This work also established water quality baselines for both study sites through in situ water sampling and testing and further ex situ analysis. As an indirect systems approach to linking sustainable development and the Caribbean, an audit of the Caribbean’s primary and secondary school’s system was conducted and recommendations suggested for the infusion of sustainability into formal education both during and after the United Nations Decade for Education for Sustainable Development (2005-2014).

The goal of this thesis was to define the nature and outcomes of Australian professional supervision by applying Holloway's (1995) Systems Approach to Supervision (SAS) across professional groups. Many Australian professionals such as psychologists, counsellors, and accountants are required to participate in some form of supervision before being granted permission, via registration, to practice independently within their respective fields. This is the first study of its kind to investigate the supervision experience of a range of professional groups within Australia. The SAS model (Holloway, 1995) provided a well-researched theoretical and practical framework with the potential to be applied across professional groups for the purposes of developing, evaluating and enhancing supervisor and supervisee practice. Based on the model, Holloway proposed a number of teaching tasks and functions in a matrix to explain the process of supervision and to assist in the professional and personal development of supervisees. To date, most of the literature on professional supervision has failed to provide a theoretical framework from which results could be meaningfully interpreted. This thesis outlines a program of research which used the SAS model as a theoretical basis for understanding and evaluating the experience of supervision amongst a range of Australian professional and its relationship to effective professional practice. Four studies were conducted in accordance with Mackenzie and House's (1979) Model of Scientific Inquiry. The first study (Study One) was exploratory in nature, and aimed to define the term "supervision" and the anticipated outcomes of supervision activities. The second study (Study Two) was also exploratory in nature, and aimed to evaluate the modes of supervision delivery as well as to collect information regarding the key tasks and functions utilised in professional supervision. The third study (Study Three) was empirical in nature, and investigated the supervision experience of psychologists engaged in supervision in accordance with the SAS model (Holloway, 1995). It longitudinally tracked their performance over a 12-month period as evaluated by both their supervisors and work managers. The fourth study (Study Four) was confirmatory in nature, and was the same as the third study but comprised a different sample of business and accounting (who were not Certified Public Accountants) graduates. The four studies consisted of four separate samples surveyed with self-report measures developed from the SAS model (Holloway, 1995) by the researcher. Study One comprised a sample of 210 supervisor-supervisee dyads. Professional groups in this sample were psychologists, counsellors, nurses, occupational therapists, financial advisors, business consultants, and accountants (without CPA) all of whom were participating in a supervision process. Study Two comprised a total of 200 supervisees broken down into four groups of 50. The professional types included in this sample were psychologists, counsellors, nurses and business consultants and accountants (without a CPA). Study Three comprised 513 supervisees who were participating in supervision as part of the criteria to become fully registered psychologists. Study Four included 480 business consultants and accountants (without CPA) who were in the early years of their career and were participating in supervision as part of their professional development. The central aims of the supervision experience, according to supervisees and supervisors, were to develop skills in counselling, case experience, professional experience, emotional awareness, the ability to self-evaluate and network. The six reported outcomes of supervision were that professional supervision enhanced supervisees' ability to self-evaluate, gain academic knowledge, become emotionally aware, develop profession networks, develop both professional and work skills and to build on relationship skills. The findings supported and extended the SAS model (Holloway, 1995) by adding the tasks of academic knowledge and networking. The definition of supervision found in this research program also supported and built on the definitions already provided in the literature. There was considerable support for the SAS model's matrix in that particular supervision functions employed to teach certain supervision tasks were more effective than others. For example, on the one hand, to teach a supervisee the skill of emotional awareness, a supervisor is best advised to take a supportive/sharing approach. On the other hand, it was shown that the teaching strategy of monitoring/evaluating was not found to be conducive to teaching case conceptualisation skills. The findings also suggested two enhancements to Holloway's original conceptualisation of the SAS model of supervision delivery mode and supervisor allocation. Furthermore, the findings confirmed that the SAS model can be applied to teach and objectively evaluate supervision success by supervisors and managers across professional groups. There were six major contributions of this research program to the field of professional supervision: First, there was the application and validation of a theoretical model, Holloway's (1995) Systems Approach to Supervision, to the supervision experience. Second, there was the development and application of scales to measure supervision performance and satisfaction reliably and with demonstrated construct validity. Third, the methodology which included the collection of both qualitative and quantitative responses from supervisees, supervisors, and managers provided a multi-method approach to understanding professional supervision across professional groups. Fourth, a uniform definition of supervision was identified across a range of professional groups. Fifth, Holloway's supervision teaching matrix was empirically supported and the findings recommend it as a mechanism for developing, evaluating and enhancing supervisor and supervisee practice across a range of professional types. The SAS model was found to be relevant to health-related professional groups but also supported in business-related professional groups. Finally, the research recommended some modifications to the SAS model to incorporate factors such as supervision delivery mode. These additions and the results of the longitudinal research suggested that supervision effectiveness was a predictor of on the job performance ratings by managers. Based on a scan of the literature to date, this research program outlines the first longitudinal empirical study of the relationship between supervision effectiveness and on-the-job performance using a range of professional groups. Limitations and future directions were discussed.

A qualitative description of the personal armour design system is elicited by comparing armour throughout the ages. Inputs that 'shape' designs are the materials technology, threat, wearer, task and environment. The emergent properties of protection, ergonomic effectiveness and financial cost form the basis of trade-offs to select final solutions. Work on the protection subsystem refines the key positive emergent property of personal armour. Existing quantifications of protection effectiveness are rejected in favour of a novel measure named the Usefulness Factor, UF. This is the first measure that accounts for the real benefit of armour. A five-stage model is proposed for the assessment of protection. Two feedback loops - due to making tasks as safe as possible and the ergonomic penalty of armour are evident. These must be considered in order to assess protection correctly. Casualty reduction analysis software (CASPER) is used to produce 'approach plots' and 'zones of usefulness' in order to make tasks safer and map the benefit of armour. This approach is demonstrated with the UK's Lightweight Combat EOD Suit against L2A2 and No. 36 Mills grenades, an HB876 area denial mine, a BL 755 sub-munition and a 105mm artillery shell. Assessment of secondary fragmentation from antipersonnel (AP) blast mines defines a threat input that is specific to Explosive Ordnance Disposal (EOD). Trials are carried out with explosive charges of 50g to 500g, buried under 5 or 10cm of stones and sand at a range of 1m. The threat is defined in terms of the probabilities of (a) being hit, (b) a hit perforating armour and (c) a hit incapacitating an unarmoured person. The chances of being hit close to the ground decrease to approximately 15% of the value when directly above the mine. Secondary fragmentation is not likely to perforate armour that protects against primary fragments. However, it is likely to incapacitate an unarmoured person. Protection is traded-off against proxies for ergonomic and financial cost effectiveness by using quantitative optimisation of personal armour. This introduces the concept of a 'protection optimisation envelope', which defines the bounds of possibility rather than a single solution. CASPER is adapted to produce weight and cost as well as incapacitation parameters. This provides a model that generates both benefits and constraints of armour. Hence, the foundations are laid for the world's first fully integrated personal armour design tools. The ergonomic effectiveness subsystem is the primary constraint of personal armour. Visor demisting for the UK's Mk 5 EOD Suit provides a simple example. Existing methods of assessment of the ergonomic penalty of armour are considered. A novel development of biomechanics computational models is proposed to predict both the mechanical and thermal burdens of armour.

A Avaliação de Impacto Ambiental (AIA), uma ferramenta internacionalmente difundida e estabelecida, apresenta limitações em relação à influência que exerce sobre as decisões tomadas, que sugerem um baixo grau de efetividade para o instrumento. Nesse contexto, a análise de sua efetividade tem sido realizada a partir de diferentes abordagens, com prevalência de estudos focados em procedimentos específicos e/ou partes do processo de AIA, ou, ainda, orientados para a verificação do cumprimento de critérios ou diretrizes para sua aplicação. Diante de sua complexidade, sugere-se, então, que tanto a AIA quanto os fatores intervenientes em sua efetividade sejam compreendidos a partir de um enfoque mais amplo, que considere as relações existentes entre as etapas do processo, seus componentes e atores envolvidos. O desenho da pesquisa realizada se orienta por elementos desenvolvidos no campo da Teoria Geral dos Sistemas e, como tal, assume que as diferentes relações entre os componentes de sistemas complexos fazem emergir propriedades que condicionam o seu próprio funcionamento. Adotando-se como objeto de estudo os sistemas de AIA e licenciamento ambiental implementados nos estados de São Paulo e Minas Gerais (Sul de Minas), o presente trabalho é voltado para a identificação e discussão dos fatores intervenientes na efetividade da aplicação dos instrumentos envolvidos, a partir de um enfoque sistêmico. Dentre as ferramentas sistêmicas existentes foi escolhida a Soft Systems Methodology (SSM) conhecida por fomentar o aprendizado dos atores envolvidos e aplicada a sistemas não quantificáveis como a AIA para identificar as lacunas e propor ações para melhoria destes dois sistemas. Os resultados obtidos permitem apontar diferenças na organização e capacidade de resposta dos sistemas estudados, concentradas na estruturação do órgão ambiental, na definição do escopo, nas janelas de participação, na quantidade de atores envolvidos nas arenas de decisão e no tempo de trâmite dos processos. As principais limitações identificadas para os dois sistemas estão em consonância com o que aponta a literatura internacional, que incluem a participação, a consideração de alternativas para o projeto, a avaliação de efeitos cumulativos e a influência de fatores externos na tomada de decisão. A abordagem utilizada apresentou-se como interessante para avaliar os sistemas de AIA, contribuindo para um melhor entendimento de sua organização e funcionamento. / Environmental Impact Assessment (EIA), an internationally widespread and established tool, has limitations with respect to its influence on decision-making, suggesting a low degree of effectiveness for the instrument. In this context, its effectiveness analysis has been carried out from different approaches, with a prevalence of studies focused on specific procedures and/or parts of the EIA process, or even targeted for the verification of compliance with criteria or guidelines for its implementation. Given its complexity, it is suggested, then, that both the EIA as intervening factors in its effectiveness are understood from a broader approach that considers the relationships between the steps of the process, its components and actors involved. The design of the research is guided by elements developed in the field of General Systems Theory and, as such, assumes that the different relationships between components of complex systems are emerging properties that determine its own functioning. Adopted as the study object the EIA and environmental licensing systems implemented in the states of São Paulo and Minas Gerais (Sul de Minas), the present work is focused on the identification and discussion of the factors involved in the effectiveness of the application of the instruments involved, based on a systemic approach. Among the existing systemic tools was chosen the Soft Systems Methodology (SSM) known to foster learning of the actors involved and applied to non-quantifiable systems like EIA to identify gaps and propose actions for the improvement of these two systems. The results may point out differences in the organization and responsiveness of the studied systems, concentrated in environmental agency structuring, in the scope, in the participation windows, in the number of actors involved in the decision arenas and in the processes time. The main constraints identified for the two systems are in line with the international literature points, which include participation, consideration of project alternatives, the assessment of cumulative effects and the influence of external factors in decision-making. The approach presented as interesting to evaluate the EIA systems, contributing to a better understanding of its organization and operation.

Electronic networking is becoming a familiar tool in higher education and research. Because the cost of telecommunications is decreasing, while the power of electronic networks and related computing resources is increasing, the resources and systems of electronic networks can now be used more easily. Access to the new global system of electronic networking has a great potential for the development of information services in South Korea. The principal aim of the research presented here is to determine what campus-wide and nation-wide information system will enable academic and research institutions in South Korea to share their information resources in an effective and efficient way via high-speed networks. The situation in South Korea has been modelled using Checkland's soft systems methodology. Data have been collected via both questionnaires and interviews, using a stratified sample of six South Korean universities as the main source. The factors at work have been examined, and the implications for the university system and for electronic networking in South Korea are considered.
