Full textAbstract:
The Asbestos Hazard Emergency Response Act (AHERA) requires public schools to manage asbestos containing materials. Twenty five years after AHERA was enacted public schools continue to struggle with documenting and managing asbestos containing material assets. In addition, the manufacturing of lead based paint (LBP) was banned over thirty years ago yet public schools continue to have to manage LBP assets with no guidelines specific to public schools. When compared to current civil infrastructure asset management systems, AHERA and the HUD guidelines lack a rating system based on visual inspection data. The development of a condition index algorithm and risk of failure model would provide school planners an efficient management tool to predict the future condition of asbestos containing material and lead based paint assets. As a result, school planners would be able to prioritize maintenance, repair, and abatement projects based on the risk to the indoor air quality of their facilities and more efficiently utilize their limited resources to mitigate such risks. This paper presents initial work toward the development of a visual condition index algorithm and a risk of failure model to support prioritization of maintenance, repair, and abatement projects. The condition assessment categories provided by AHERA and HUD were adapted and incorporated in an evaluation form created to assist in rating the various stages of accessibility, deterioration, and detection of typical ACM and LBP building components. The evaluation form can be utilized by inspection and school personnel when reclassifying ACM and LBP components during semi-annual inspections of their facilities and also ensure the repeatability of the condition assessment and risk of failure methodologies. A risk of failure model was developed utilizing the FMEA process, specifically the calculation of a risk priority number (RPN). Three schools were selected for a field pilot study to develop the accessibility, deterioration, detection, and RPN algorithms and evaluate for repeatability. The algorithms will provide a quantitative and consistent means for documenting the condition and RPN of asbestos containing material and lead based paint assets and allow the condition of these assets to be monitored and reclassified over a period of time.Ph.

Bigdeli, Farah. "Risk Assessment and Risk Management of Nano-Material Toxicity." ScholarWorks@UNO, 2009. http://scholarworks.uno.edu/td/921.
Full textAbstract:
Increasing applications of nano materials in medicine, construction, textiles, computers, and other consumer goods have lead to increasing concerns of their effect on human health and ecology during synthesis, manufacturing, use, and disposal of nano-materials. Though much scientific progress has been made in nano material synthesis, manufacturing, and application in consumer goods and other sectors such as medicine, textiles and more, not much progress has been made in understanding the adverse effects of nano materials on human health and the environment. Physical, chemical, toxicological characteristics of these nano materials and their fate in the environment are important in understanding their adverse effects on the environmental and human health. This study is aimed at developing a preliminary framework for risk assessment (RA) and risk management (RM) of nano materials based on fundamental principles of chemistry, physics, toxicology, and other related disciplines.

Full textAbstract:
The commercial mining of asbestos occurred in four Provinces of South Africa (Northern Cape, North West, Limpopo and Mpumalanga). It was initiated in the late 1800's and lasted for over a hundred years into the beginning of this century. As a producer of amphibole asbestos, South Africa far outpaced every other country being responsible for 97% of global production. The last crocidolite mine closed in 1996 and chrysotile in 2002. Anecdotal information concerning environmental contamination as a result of the former mining activities and the improper disposal of mine waste tailings has been reported by a variety of authors. Few comprehensive or systematic surveys have been conducted to date to document this issue and very little quantifiable research has been completed on the communities located in close proximity to the former mine sites to determine the extent of contamination. In 2004-2006 communities were surveyed within the Northern Cape and North West Provinces to determine the extent and severity of environmental contamination. This research developed and applied a methodology to select those communities suspected of environmental contamination, a targeted survey methodology, and a protocol for rapid sample laboratory analysis. A total of 41 communities were initially predicted by the model to be suspected for environmental asbestos contamination. Based on the inclusion of local knowledge, a final 36 communities were selected for a screening-level field assessment, 34 of which were found to contain environmental asbestos contamination at rates ranging from 20 to 100% of the surveyed locations. A total of 1 843 samples of soil and building material were collected in the screening level assessment. One community (Ga-Mopedi) was selected as being representative of the total cohort and a more detailed house to house survey was completed. A total of 1 486 samples were collected during the detailed survey. Results of the detailed survey revealed 26.2% of the homes were contaminated with asbestos containing soil and/or building material. A theoretical quantitative cumulative exposure assessment was developed to estimate the disease burden within the study area population of 126,130 individuals within the surveyed communities resulting in a predicted range of 25-52.4 excess deaths per year from lung cancer and mesothelioma due solely to environmental exposures to asbestos pollution.

Full textAbstract:
Traditional methods of project management are not appropriate for complex projects anymore. Since projects are becoming increasingly complex and uncertain, interaction between activities and resources is growing in ways not considered by these methods. Nowadays, managers need more agile project management methods that are able to recognize and deal with uncertainty and to produce the expected results. Lean project management, the most recent approach of lean methodology, appears as an alternative approach capable of dealing with complexity and uncertainty. The latest investigations in the field show that traditional methods are still adequate for simple projects, while lean methods are more appropriate for complex projects. This thesis aims to investigate the nature of lean project management and to examine project risk management processes so that managers can assess the complexity of projects before their beginning and decide which method to apply in order to manage them.

Full textAbstract:
This thesis studies the Chinese banks’ credit risk assessment using the Post Keynesian approach. We argue that bank loans are the major financial sources in emerging economies and it is uncertainty, an unquantifiable risk, rather than asymmetric information about quantifiable risk, as held by the mainstream approach, which is most important for the risk attached to credit loans, and this uncertainty is particularly important in China. With the universal existence of uncertainty, borrowers and lenders have to make decisions based on convention and experience. With regard to the nature of decision-making, this implies the importance of qualitative methods rather than quantitative methods. The current striking problem in Chinese banking is the large amount of Non-Performing Loans (NPLs) and this research aims to address the NPLs through improving credit risk management. Rather than the previous literature where Western models are introduced into China directly or with minor modification, this work advocates building on China’s conventional domestic methods to deal with uncertainty. We briefly review the background of the Chinese banking history with an evolutionary view and examine Chinese conventions in the development of the credit market. Based on an overview of this history, it is argued that Soft Budget Constraints (SBC) and the underdeveloped risk-assessing mechanism contributed to the accumulation of NPLs. Informed by Western models and experience, we have made several suggestions about rebuilding the Chinese convention of credit risk assessment, based on an analysis of publications and interviews with Chinese bankers. We also suggest some further development of the Asset Management Companies (AMCs) which are used to dispose of the NPLs.

Kythreoti, Stella. "Earthquake risk assessment and management : case study, Cyprus." Thesis, University of Sheffield, 2002. http://etheses.whiterose.ac.uk/3417/.
Full textAbstract:
Earthquakes are amongst the worst natural disasters on Earth, resulting in an annual average of around 10,000 fatalities last century and progressively increasing in the amount of economic damage they cause, reaching US $20 billion per annum this decade. The mitigation of the unwanted consequences of earthquakes is normally achieved by Risk Management Strategies (RMS), which rely on the development of Earthquake Risk Assessment (ERA) techniques. This thesis aims to develop a framework for ERA for medium seismicity regions that incorporates the spatial aspects of the hazard and risk evaluation. The framework is used to undertake ERA for the island of Cyprus, and the information is used to propose RMS. The ERA framework relies on comprehensive data on the location, value and vulnerability of buildings and the population distribution. These data were collected from the various Cyprus Government Departments. Various hazard and attenuation models are examined, and the effect of their variability is taken into account through Monte Carlo simulations. The estimated annual risk for Cyprus is just below £ 10 million CY. This value was estimated based on the use of the re-appraised historical data for the past-century. Comparisons with other seismic hazard assessment methods, such as recurrence relationships, have revealed that, without a spatial distribution model, such approaches are unsuitable for ERA. Though the maximum intensities predicted are in line with the ones that underpin the aseismic code of Cyprus (CCEAA-CFEE, 1994), the predicted design accelerations are higher than given in the code. Hence, new seismic accelerations are proposed. Despite that, the current reduction in risk is comparable to the additional cost of aseismic design. Seismic retrofitting was also examined and it was found that as part of a general modernisation scheme seismic upgrading is cost effective. However, whatever the state of the building, it is recommended that earthquake insurance should be made mandatory. The current seismic insurance rates appear to be fair, though they seem to underestimate the risk in the areas of high seismicity. The number of likely human losses is also estimated. This study concludes that the result of ERA is heavily dependent on the models and data used, and both require constant updating for the ERA results to remain meaningful.

Alzahmi, M. "The collaborative risk assessment environment in disaster management." Thesis, University of Salford, 2015. http://usir.salford.ac.uk/38030/.
Full textAbstract:
In the past century the occurrence of natural disasters and man-made disasters have steadily increased with a significant loss of life, damage caused to infrastructure and property, and destruction of the environment. There is much evidence that natural disasters are growing on a global level. Dealing with disasters demand the involvement of a range of agencies collaborating and making collaborative decision. This research has identified the need for a collaborative platform to bring together a variety of information to enable multi-agencies to prepare for disasters and to enhance the resilience of cities. Risk assessment is a crucial aspect within the activities of multi-agencies. Risk assessment enhances emergency planning which can then be tested by detailed appraisals and exercises. Whenever risk assessment is updated, plans are revised and additional tests are carried out. Risk assessment helps multi-agency planners decide what resource requirements they need and what multi-agency activities need to be planned collaboratively in order to prepare for disaster. The aim of this research is to investigate the nature of an interactive map that can enhance multi-agency team collaboration in the risk assessment process in disaster management. This research uses the six-step risk assessment process used in Australia and New Zealand which is widely recognized as being good practice. These steps are Contextualization, Hazard Review, Risk Analysis, Risk Evaluation, Risk Treatment and Monitoring and Reviewing (Standards Australia/Standards New Zealand Standard Committee, AS/NZS ISO 31000:2009). In this research, the characteristics of a suitable interactive map for risk assessment was defined in collaboration with the senior practitioners within a multi-agency team in the UK. Semi-structured interviews were conducted with the senior managers of Category 1 responders in The Greater Manchester Local Resilience Forum (GMLRF) to capture the requirements for a multi-agency collaboration platform. The outcome of these interviews were used to capture the characteristics and develop the a prototype of the interactive map that can support risk assessment. Once implemented, the validation of the interactive map prototype was conducted involving senior practitioners of stakeholders in the GMLRF development group. The experiment was held in the THINKpod in ThinkLab, at the University of Salford. A total of 23 senior practitioners took part in the evaluation experiment. After a demonstration of a scenario and using the interactive map, the participants evaluated the prototype as a group and then completed questionnaires that xv featured range of open, closed and rating scale questions. These questionnaires were designed to evaluate the perceived effectiveness and impact of the interactive map on strengthening collaboration among the multi-agency teams during risk assessment. The outcome of the evaluation shows a good level of satisfaction among the practitioners. The overall result suggests that the professionals view the interactive map as a good platform to support collaboration multi-agency teams in risk assessment activity.

Full textAbstract:
Real-world problems especially the ones that involve natural systems are complex and they are composed of many non-deterministic components. Uncertainties associated with these non-deterministic components may originate from randomness or from imprecision due to lack of information. Until recently, uncertainty, regardless of its nature or source has been treated by probability concepts. However, uncertainties associated with real-world systems are not limited to randomness. Imprecise, vague or incomplete information may better be represented by other mathematical tools, such as fuzzy set theory, possibility theory, belief functions, etc. New approaches which allow utilization of probability theory in combination with these new mathematical tools found applications in various engineering fields. Uncertainty modeling in human health risk assessment and groundwater resources management areas are investigated in this thesis.
In the first part of this thesis two new approaches which utilize both probability theory and fuzzy set theory concepts to treat parameter uncertainties in carcinogenic risk assessment are proposed. As a result of these approaches fuzzy health risks are generated. For the fuzzy risk to be useful for practical purposes its acceptability with respect to compliance guideline has to be evaluated. A new fuzzy measure, the risk tolerance measure, is proposed for this purpose. The risk tolerance measure is a weighed average of the possibility and the necessity measures which are currently used for decision making purposes. In the second part of this thesis two decision making frameworks are proposed to determine the best groundwater resources management strategy in the Savannah region, Georgia. Groundwater resources management problems, especially ones in the coastal areas are complex and require treatment of various uncertain inputs. The first decision making framework proposed in this study is composed of a coupled simulation-optimization model followed by a fuzzy multi-objective decision making approach while the second framework includes a groundwater flow model in which the parameters of the flow equation are characterized by fuzzy numbers and a decision making approach which utilizes the risk tolerance measure proposed in the first part of this thesis.

Alghanmi, A. "Risk assessment and management of petroleum transportation systems operations." Thesis, Liverpool John Moores University, 2018. http://researchonline.ljmu.ac.uk/9160/.
Full textAbstract:
Petroleum Transportation Systems (PTSs) have a significant impact on the flow of crude oil within a Petroleum Supply Chain (PSC), due to the great demand on this natural product. Such systems are used for safe movement of crude and/or refined products from starting points (i.e. production sites or storage tanks), to their final destinations, via land or sea transportation. PTSs are vulnerable to several risks because they often operate in a dynamic environment. Due to this environment, many potential risks and uncertainties are involved. Not only having a direct effect on the product flow within PSC, PTSs accidents could also have severe consequences for the humans, businesses, and the environment. Therefore, safe operations of the key systems such as port, ship and pipeline, are vital for the success of PTSs. This research introduces an advanced approach to ensure safety of PTSs. This research proposes multiple network analysis, risk assessment, uncertainties treatment and decision making techniques for dealing with potential hazards and operational issues that are happening within the marine ports, ships, or pipeline transportation segments within one complete system. The main phases of the developed framework are formulated in six steps. In the first phase of the research, the hazards in PTSs operations that can lead to a crude oil spill are identified through conducting an extensive review of literature and experts’ knowledge. In the second phase, a Fuzzy Rule-Based Bayesian Reasoning (FRBBR) and Hugin software are applied in the new context of PTSs to assess and prioritise the local PTSs failures as one complete system. The third phase uses Analytic Hierarchy Process (AHP) in order to determine the weight of PTSs local factors. In the fourth phase, network analysis approach is used to measure the importance of petroleum ports, ships and pipelines systems globally within Petroleum Transportation Networks (PTNs). This approach can help decision makers to measure and detect the critical nodes (ports and transportation routes) within PTNs. The fifth phase uses an Evidential Reasoning (ER) approach and Intelligence Decision System (IDS) software, to assess hazards influencing on PTSs as one complete system. This research developed an advance risk-based framework applied ER approach due to its ability to combine the local/internal and global/external risk analysis results of the PTSs. To complete the cycle of this study, the best mitigating strategies are introduced and evaluated by incorporating VIseKriterijumska Optimizacija I Kompromisno Resenje (VIKOR) and AHP to rank the risk control options. The novelty of this framework provides decision makers with realistic and flexible results to ensure efficient and safe operations for PTSs.

Infrastructure development represents one of the major hindrances to economic growth and social development across all countries worldwide. A one percent increase in GDP is expected in a country with an estimated ten percent increase in infrastructure assets. Private project and structured financing is identified as the most effective tool for the provision of the required infrastructure.
The complexity, formidable risks and highly leveraged nature of project and structured financing transactions account for the mismatch between the numbers of infrastructure financing transactions that reach financial close compared to the available pipeline. Increased literature focusing on the public sector procurer and private sector contractor is available in project and structured financing transactions, but scarce research focuses on the risk assessment processes applied by financiers to the due diligence of transactions.
In this study, 15 in-depth semi-structured interviews were conducted with financing experts representing a diverse set of expertise with varying levels of experience in different markets. ATLAS.ti was used to analyse, code and identify themes in the data collected.
The findings indicate a wide range of risks and scenarios are considered by financiers with the top risks being political or sovereign risk followed by construction risk. From the findings discussed, a financiers generalized risk assessment framework is created that can be applied to a wide range of project financing transactions and markets in context.Mini Dissertation (MBA)--University of Pretoria, 2015.

Full textAbstract:
Environmental risks are traditionally assessed and presented in non spatial ways although the spatial relations between the risk assessment components and the spatial distribution of the risk assessment variables strongly influence exposure estimations and hence risks. According to the scale of the problem, two different spatial risk assessments approaches can be identified: site-specific spatial risk assessment and regional risk assessment. In the present Ph.D. thesis the first approach applies geostatistic interpolation methods for mapping the distribution of contaminants concentration in order to support the risk-based zoning of the site. It was implemented in DESYRE (DEcision Support sYstem for the REqualification of contaminated sites) and applied to the Porto Marghera case study. At regional scale, an innovative methodology integrating a relative risk approach and spatial analysis was developed to select sites at regional scale where a preliminary soil investigation is required first. It was implemented in SYRIADE (Spatial decision support sYstem for Regional rIsk Assessment of DEgraded land) and applied to the Upper Silesia case-study.Tradizionalmente nella valutazione dei rischi per l’uomo e per l’ambiente, le relazioni spaziali tra le componenti dell’analisi di rischio e la distribuzione spaziale delle variabili coinvolte non vengono adeguatamente considerate, sebbene esse influiscono sulla valutazione dell’esposizione e quindi del rischio. In base alla scala di analisi, si possono identificare due approcci di analisi di rischio (AR): l’AR spaziale sito-specifica e l’AR regionale. Nella presente tesi di dottorato è stata sviluppata una procedura di AR spaziale sito-specifica che utilizza metodi di interpolazione spaziale per ottenere delle mappe di distribuzione della contaminazione al fine di supportare la zonizzazione del sito sulla base dei livelli di rischio. A scala regionale è stata sviluppata una metodologia innovativa che integra un approccio di AR relativo con analisi spaziali, per selezionare i siti dove le attività di caratterizzazione sono urgentemente richieste. Le due metodologie sono state implementate rispettivamente in DESYRE (DEcision Support sYstem for the REqualification of contaminated sites) e in SYRIADE (Spatial decision support sYstem for Regional rIsk Assessment of DEgraded land) e applicate al sito di Porto Marghera e alla regione dell’Upper Silesia.

Apostolopoulos, Charalampos. "Risk assessment for change management within project management : a hierarchical model process approach." Thesis, City University London, 2015. http://openaccess.city.ac.uk/15015/.
Full textAbstract:
The field of modern project management is not new, and what seems to have changed over the past decade is the evolution of techniques applying theory into practice. This had as a consequence for the need to standardise and structure different processes of project management, in a detailed, documented and formal manner. On the other hand, change management seen as an integrated process within project management is a rational process for exploring decision and behaviour alternatives in an attempt to realign the course of ‘derailed’ deliverables due to change and ensure project success. However, models contained in such frameworks often lack formal semantics and clarity; generally fail to address and assess organisational change management risk reasoning, in a rather detailed way as they do for the majority of the project management processes. Since, uncontrolled changes might have an effect on the projects’ success, it is vital to assess the probability of materialisation (risk) of success before the decision is made and whether to proceed with the change or not. For example, if the change dramatically increases the risk of failure then it is logical to assume that avoiding that implementation is the right decision. Ideally, a change or consequence based upon a decision should have a low impact and a fairly high level of predictability. This research, takes the challenge to propose a novel modelling approach, which will contribute significantly to the missing formality of business models especially in the change risks assessment area. The introduction of Change Risk Assessment Model (CRAM) allows the identification and definition of speculative relationships, between change risks in the form of hierarchical risk tree analysis. Overall, the method is dynamic and flexible enough that can be tailored to various project requirements, taking into account significant environmental risk factors which influence project deliverables. Project success is a key objective for today’s organisations; professionals can make use of a new methodology for risk assessment, compatible with project management frameworks which currently seems to be missing from literature. Project management methodologies are not a panacea against project failure; nevertheless, CRAM can be regarded as a comprehensive modelling approach which combines both quantitative and qualitative risk criteria analysis in decision making processes.

Thesis (MEng)--Stellenbosch University, 2003.ENGLISH ABSTRACT: Whenever projects fail, analysis of the causes has shown that risks were present from day one. Often individuals at some level in the project team have knowledge of these risks and they could have been identified and appropriate remedial action taken. Risk, whether identified or not, generally results in some increase in financial exposure on behalf of the organisation, but, if managed well, offers a potential that could lead to increased profits. There has been a tremendous explosion regarding the amount of data that organisations generate, collect and store. Managers are beginning to recognize the value of this asset and are increasingly relying on intelligent systems to access, analyse, summarise and interpret information from large and multiple data sources. These systems help them to make critical decisions at a faster rate or with a greater degree of confidence. Data mining is a promising new technology that helps bring intelligence into these systems. The purpose of this thesis is to present a methodology that integrates a data mining technique with a decision support system in order to form an intelligent decision support system. The implementation of such an intelligent decision support system will enable project and project risk managers to improve the management of and reduce risk within a project. This thesis consists of two sections. The first section describes the processes and characteristics of project management, project risk management, data mining and decision support systems. The aim is to provide the reader with a background about these four management methodologies. The second section describes the methodology of how the processes of project and project risk management can benefit from the integration of a data mining technique and a decision support system. An application that uses the case-based reasoning approach as a data mining technique to intelligently profile a project according to its risks is demonstrated.
AFRIKAANSE OPSOMMING: Wanneer projekte misluk, toon 'n analise van die oorsake dat risiko's vanuit die staanspoor daar teenwoordig was. Individuele persone op verskillende vlakke in die projekspan is dikwels daarvan bewus. Hierdie risiko's kon geïdentifiseer gewees het en regstellende stappe kon geneem gewees het. Risiko, hetsy geïdentifiseer of nie, loop gewoonlik uit op 'n sekere mate van toename in finansiële blootstelling namens die organisasie, maar wanneer dit goed bestuur word, bied dit 'n potensiaal vir verhoogde wins. Daar is 'n geweldige vermeerdering in die hoeveelheid data wat organisasies genereer, versamel en berg. Bestuurders begin alreeds die onskatbare waarde van hierdie bate besef en steun toenemend op intelligensiestelsels vir toegang, analise, opsomming en interpretasie van inligting van omvangryke en veelsoortige databronne. Hierdie sisteme stel hulle in staat om kritieke besluite vinniger of met 'n groter mate van vertroue te neem. Dataontginning is 'n belowende nuwe tegnologie wat daartoe bydra dat intelligensie in hierdie sisteme ingebring word. Die doel van hierdie tesis is om 'n metodologie wat 'n dataontginningstegniek met 'n besluitnemingsondersteuningsisteem integreer sodat 'n intelligente besluitnemingsondersteuningsisteem gevorm kan word. Die implementering van so 'n intelligensie besluitnemingsondersteuningsisteem sal projekbestuurders en projekrisikobestuurders in staat stelom die bestuur van 'n projek te verbeter en die risiko binne die projek te verminder. Hierdie tesis word in twee dele aangebied. Die eerste deel beskryf die prosesse en karakteristieke van projekbestuur, projekrisikobestuur, dataontginning en besluitondersteuningsisteme. Sodoende word aan die leser agtergrondinligting van hierdie vier bestuursmetodologieë verskaf.

Full textAbstract:
Risk assessment and risk management now underpin environmental protection in the UK. Risk assessment provides for a structured and systematic analysis of a problem, and is an objective tool to inform risk management decisions. In particular, risk assessment can assist in the prioritisation of management activities to direct resources more effectively to significant risks. However, the application of risk assessment remains ad hoc and often focused on quantified approaches. The problem of how to integrate the results of a risk assessment into decisionmaking processes remains. The objective of this research was to assess whether a knowledgebased approach could be usefully applied to risk management decisions associated with the protection of groundwater. The use of a knowledge-based system offers considerable potential to support regulatory decision-making relating to environmental risks. Such systems utilise expert knowledge to solve specific problems as an expert would but without requiring specialist or skilled users. This research describes the development of a prototype decision-support system to assist non-specialist regulatory personnel, in the prioritisation of risks and management activities relating to groundwater threats from hydrocarbon point-sources. The research focused on the knowledge acquisition process using semi-structured interviews, concept sorting and risk rating to identify the type of information required by the expert in their decision-making processes and also to distinguish any differences of approach between experts and 'non-experts'. A conceptual model was developed that represented expert decision-making and problem solving. This model was used to develop the prototype decision-support system which was subsequently evaluated by experts and users, resulting in system refinements. A positive response to the usability and utility of the system was received from both expert and user groups, suggesting a knowledge-based approach can be usefully applied to risk management decisions associated with the protection of groundwater.

Full textAbstract:
Bycatch is one common aspect of fisheries worldwide and recognized as one of the significant impacts over protected and threatened species, chondrichthyans among them. This thesis aims to help mitigate and provide tools to aid the conservation of chondrichthyans. In the first data chapter I developed a model of risk assessment to quantify relative vulnerability of the group based on spatial overlap of natural distributions and fishing events and related to the species resilience. In this study I used commercial fisheries data provided by the Australian Fisheries Management Authority and applied the method to bycatch chondrichthyans and target species. Results were consistent with IUCN status of the species, including cases with regional differences from global status. In the second data chapter, spatial and seasonal distribution of chondrichthyan bycatch events in southern and eastern Australia were analysed. Results indicate differences in rates between gears and also the importance of oceanographic factors to bycatch ratio as well to catch per unit of effort whilst diversity is more influenced by gear type. The spatial analyses also indicated hotspots for bycatch in the Great Australian Bight and Bass Strait. In the third data chapter, I estimated the age, growth and reproductive parameters of the Eastern Fiddler Ray Trygonorrhina fasciata and the Sydney Skate Dipturus australis, two endemic species often caught as bycatch. Age estimates, based on vertebrae bands, were used to calculate growth parameters, which were similar to related species. Moreover, based upon the somatic and gonad indexes, reproductive biology information of these species is provided. In the fourth data chapter I describe the diet and estimated trophic levels of these batoids. Results indicated a diet consisting largely of crustaceans and place the species within the range of trophic level for closest relatives and support their status as mesopredators on the region.

Full textAbstract:
A review of the literature regarding risk management and effective risk communications identified that very few researchers have addressed risk assessment confidence levels when using risk scoring methods. The focus of this research is to develop a definition of risk assessment confidence levels for use in internal project management communications and to evaluate its usefulness. This research defines risk assessment confidence level as "The degree of certainty that the likelihood or consequence score (assigned by the risk assessor) reflects reality." A specific level of confidence is defined based on the types of analyses that were conducted to determine the risk score. A survey method was used to obtain data from a representative sample of risk assessment professionals from industry and academia to measure their opinion on the usefulness of the defined risk assessment confidence levels. The survey consisted of seven questions related to usefulness--four questions addressed the importance of stating confidence levels in risk assessments and three addressed the usableness of the proposed confidence level. Data were collected on the role and experience level of each of the respondents and the survey also included a comment section to obtain additional feedback. The survey generated 364 respondents representing a broad variety of roles associated with decision making and risk management with experience levels from fairly new to experienced risk assessors. The survey data were analyzed by calculating the proportion of respondents who gave negative, neutral and positive responses to the survey questions. An examination of the roles of the survey respondents indicated that no single group was dominant. A non-parametric Kruskal-Wallis test generally failed to reject the hypothesis that the means of the survey response distributions were identical. There was one exception which indicated that there are differences based on role and by inspection of the responses, it appears that decision makers, academics, and others more strongly support the need for confidence level information to reduce the difficulty in making risk based decisions in projects. The survey responses at a confidence level of 95% have a range of errors from 3.84 to 4.97%. Based on the results of the survey, 77 – 83% of those surveyed indicated agreement that knowing the confidence the assessors have in their assessment is important and would improve a management decision. The survey showed that 60 – 86% of the respondents agreed that the confidence levels and their definitions as presented in the survey were usable. The question with the lowest agreement (60%) was related to the way in which the individual levels were defined. The ad-hoc comments provided in the survey were divided into eleven groups based on similarity of the subject of the comment and then examined for common themes. These added additional insight into the results and useful information for future research efforts. This research validates that the use of risk assessment confidence levels is considered to be useful in project risk management. The research also identified several potential areas for future work, including determining the appropriate number of confidence levels that should be defined, refining the definition of the individual confidence level definitions, examining historical perspectives of whether the risk assessments were accurate, examining the concept of shiftability of risk assessments, further research on communication of variability of risk assessments, and research into the usefulness of risk matrices.Ph.D.

Full textAbstract:
The continued rise in accident and ill health statistics throughout the member states of the European Union indicate that the standards of occupational health, safety and environmental control require further improvement to minimise the current level of loss. Management systems are regarded as an effective means of reducing this loss by continuously improving standards. Whilst there is much discussion and debate about the possibilities of integrating management systems, at present, there are no national or international published integrated management standards, although some multi-national companies have introduced their own internal integrated standards. The research explored the development of an integrated health, safety and environmental (HSE) management system within a range of industrial organisations. This included the development of tools for successful implementation of integrated systems, specifically for significance review, risk assessment and auditing. Resources and accreditation constraints precluded exhaustive testing of all clauses within the proposed integrated management standard. However, analysis of key aspects of the standard revealed: 1. The introduction and use of separate health, safety and environmental (HSE) management systems improved the standards of risk control within organisations. 2. Organisations perceived that there were clear business advantages in some form of integration of existing standards. 3. The developed integrated HSE standard was technically possible in the area of policy development, process operations, working instructions and documentation. However, the integration of risk assessment and audit tools gave limited advantages compared to existing separate systems. 4. The proposed integrated HSE standard complied with both individual European member states national legislative requirements and European/World-wide management standard criteria. In summary this thesis represents an original contribution to the field of integrated management systems. The thesis also identifies areas of further work that will increase the knowledge base, scope of application of the work carried out.

Full textAbstract:
Thesis (MBA)--Stellenbosch University, 2012.ENGLISH ABSTRACT: Severe flooding in Queensland, Australia in late 2010 and into February of 2011 resulted in significant losses to infrastructure, equipment and coal production. Xstrata Coal (XC) mines suffered billions of dollars worth of losses, resulting in insurance premiums increasing drastically in subsequent months. These events prompted Xstrata‟s top management to reconsider the way in which they managed risk. Initial revelations were that the focus of Risk Management had largely been on the areas of Health and Safety and that, particularly in South Africa, the outcome of all management‟s efforts to manage risk had been to comply with the relevant legislation. There was clearly an attempt to avoid litigation resulting in potential prosecution. The most stringent of this legislation was that of the Mine Health and Safety Act (No. 24 of 996), as promulgated by the Department of Mineral Resources. The requirements were prescriptive to the extent that mine management was required to utilise the Hazard Identification Risk Assessment process to identify hazards, assess the associated risk and apply mitigation, largely in order to prevent incidents which could affect the health and safety of employees. Little regard was given to the fact that mining houses could endure severe financial losses as a result of catastrophic events, which could stop production for significant periods of time. Whilst Xstrata did recognise Business Continuity Risk (BCR), the risk assessment process which was introduced along with the CURA risk register displayed a distinct division between Health and Safety Risk and BCR. Furthermore, this was not a systematic process. Initial risk categories were prescribed by XC mainly based on experiences in Australia. The floods prompted a rethink and Xstrata‟s prescription to conduct business continuity risk assessments (BCRAs) coincided perfectly with this writer‟s exposure to the Enterprise Risk Management Elective at the University of Stellenbosch‟s Business School. As the General Manager of the iMpunzi Complex that comprises three coalmines, it was the responsibility of the writer to carry out the instruction to review the business continuity process. Consequently, the research is intended to assess the current Risk Management environment within Xstrata Coal South Africa by means of an analysis of current documentation and interviews with select key personnel who largely influence and impact the management of risk in the company. Thereafter, the study will progress to the methodology involved in the Risk Assessments, followed by an assessment of the knowledge, skills and qualifications required for the relevant, accountable managers appointed to manage the risks. The findings of the research were that whilst there was quite a rigid framework, which was aligned with ISO 31000 principles for risk management, there were shortcomings in the methodology of the risk assessment process, as well as the considerations for dealing with latent or residual risk. To this extent, the writer recommended: A risk assessment template which prescribes, but is not limited to, the hazards which may be prevalent on a coal mine, including hazards specific to iMpunzi Complex; A revised template for the Risk Treatment Plan, which takes cognisance of Residual Risk; Other recommendations, which may deal with minor findings of the study.

Full textAbstract:
The purpose of this PhD thesis is to evaluate the volcanic risk associated with San Miguel Volcano, one of the most active volcanoes of El Salvador, through assessing volcanic hazard, that is, identify how a volcanic system (i.e., an active volcano or volcanic area) has behaved in the past and then use this information to infer how it may behave in the future. This task requires a compilation of all existing geological and geophysical information concerning the eruption style of the volcanic system in question, its eruptive recurrence, the structural constraints on the opening of new vents, and the characteristics and potential extent of its main hazards. The next step is to draw up eruption scenarios and hazard maps using the information gathered of the previous stage, which will constitute the basis for estimating exposure and vulnerability analysis, the third objective of this study.
We followed a probabilistic methodology to conduct the volcanic hazard assessment and scenario simulations. Probabilistic models are widely used in volcanic hazard assessment due to: (1) the lack of precise knowledge of the physical processes governing the dynamics of most volcanic hazards; (2) the difficulties in getting complete parameterisation sets for each phenomena; (3) the normally short time and computational costs; and (4) the acceptable results that probabilistic models provide. Thus, probabilistic or stochastic volcanic hazard analyses provide probabilistic outcomes that reflect the degree of uncertainty in the simulation.
We conducted the first systematic and comprehensive long-term hazard assessment for San Miguel using available geological data, past eruption records, stratigraphic information, and volcano-structural data, as well as new information gathered from fieldwork. We obtain a susceptibility map of the volcano and highlighted the areas with the greatest likelihood of hosting future eruptive vents. We conducted two temporal analyses, one with a forecasting time window of two years using information on volcanic activity over the past 430 years (historical period), and another with a forecasting window of six months, with information from the past 16 years (monitoring period). Then we calculated the most likely scenarios for each specific time windows. Secondly, we simulated: (1) the five most likely scenarios (ashfall scenarios, shortmedium extent, and VEI 1-2); (2) other probable scenarios related to lava flows, both according to its historical record; (3) other possible scenarios related to PDCs with similar characteristics to those that occurred during its geological history; and (4) the most hazardous scenario (ashfall, lava flow, PDC) also deduced from its geological record. We also constructed a qualitative integrated volcanic hazard map through the combination of the simulated scenarios.
Finally, we made an exposure analysis of San Miguel volcano area, considering population distribution, land use, as well as the distribution of the main infrastructures of the area. Moreover, we estimated a Vulnerability Index for the hazardous areas based on the characterization of the construction materials of walls and roofs of stocks. We constructed different exposure maps for 1) Population, 2) land use, 3) road network, 4) schools, and 5) health centers. For private houses and public infrastructures, we made an estimation of the Vulnerability Index in a village where lahars are frequent. This study was developed with the aim of improving land use and the already existing emergency plans, and pretends to be the starting point for the collaboration and coordination between scientists, the national observatory (OA-MARN), and the civil protection agency of San Miguel municipality, thus helping to strength this cooperation to face future volcanic crises related to San Miguel volcano.

Full textAbstract:
As competition in the business environment increases, knowledge management
becomes a critical success factor. Firms should be able to gather, analyze and reuse
knowledge to support their strategic decisions. Construction firms should also
analyze information in hand (completed and on going project data) and make it a
part of their learning mechanism. Post-project appraisal is an organizational learning
mechanism aiming to form an organizational memory. Organizational memory is a
remedy for organizational amnesia, which is a very common problem in the
construction industry due to the project-specific nature of the industry and lack of
systematic ways to manage knowledge. Particularly, information about risks and
their consequences is an important piece of knowledge that the firms should refer to
in the forthcoming projects in order not to do the same mistakes.
v
Risk management comprises of risk identification, analysis and formulation of risk
response strategy to maintain an optimum risk-return structure in a project. It is
agreed upon by many researchers that, although risk management is accepted as one
of the critical success factors for construction projects, project participants generally
do not have sufficient knowledge pertinent to risk management concept and the
number of tools which facilitate the risk management process is rather low.
Typically, companies carry out a risk assessment exercise at the start of a project
and the obtained risk ratings are used to determine contingency. However, after the
project is over, a final assessment is not usually carried out. The main idea in this
study is that, in order to improve the risk assessment process in forthcoming projects,
risk assessment should be a part of post-project appraisal. Risk events that actually
happened may be classified according to their sources and impacts (monetary/nonmonetary)
as well as the effectiveness of utilized response strategies. Consequently,
companies may learn from what had happened in previous projects and prepare
more realistic risk management plans in the future.
The major objective of this thesis is to develop a project risk management
information model for risk assessment using historical data in order to improve risk
assessment process in forthcoming projects. The framework is modeled to ensure
information continuity throughout the project life cycle by storing and reusing
project information that resides in risk event databases. The applicability of the
developed database system is tested on a real construction project and potential
benefits are discussed.

Full textAbstract:
Risk assessments for offenders often combine past records with current clinical findings from observations, interviews, and test data. Conclusions based on these risk assessments are highly consequential, sometimes resulting in increased criminal sentences or prolonged hospitalization. Offenders are therefore motivated to intentionally minimize their risk scores. Intentional minimization is especially likely to occur in offenders with high psychopathic traits because goal-directed deception is reflected in many of the core traits of the disorder, such as manipulativeness, glibness, and superficial charm. However, this connection appears to be based on the conceptual understanding of psychopathy, and it has rarely been examined empirically for either frequency or success. The current study examined the connection between psychopathic traits and the intentional minimization of risk factors using a sentenced jail sample. In general, offenders were able to effectively minimize risk on the HCR-20 and SAQ, while the PICTS, as a measure of cognitive styles, was more resistant to such minimization. Psychopathic traits, especially high interpersonal facet scores, led to greater minimization using a repeated measure, simulation design. Important differences in the willingness and ability to use deception were found based on (a) the content of subscales, and (b) the mode of administration (i.e., interview vs. self-report). The important implications of this research are discussed for risk assessment procedures regarding likely areas of deception and its detection. It also informs the growing literature on the connection between psychopathic traits and deception.

The methodological framework for informed decision-making known as Environmental Systems Assessment (ESA) is derived from, and is shown to contain, the existing tools of Risk Assessment, Decision Analysis and Life Cycle Assessment (LCA). Communication is identified as a problem within ESA. A panel process in local waste management between a UK Council, its local lay public and experts illustrates a new methodological implementation of ESA in which risk, decision analytic and life cycle information were all present in parallel and in different forms. These included an innovative and interactive multimedia CD-ROM tailored to the locality (known as 'WOMBLE') and the WISARD software developed with, among other bodies, the Environment Agency of England and Wales. The communications and information in the process are evaluated by social research, the learning of the participants is assessed and it is shown that while a number of significant actions were agreed upon, individual preferences were still stable and significantly different. The potential of the approach is assessed.

Full textAbstract:
Major changes with regards to digitalization and new customer behaviours have transformed the retail industry in many ways. One of the latest trends in retail is the focus on omnichannel, in order to stay competitive in today's changing market conditions. Omnichannel is about creating a seamless distribution and experience for the customers between channels. These changes that come with digitalization come with strategical and developmental challenges. As well as an increased pressure to work more efficiently and at an accelerated speed to cope with new trends. This can be hard to accomplish, to embark into unknown territory since no organization truly has reached omnichannel. Whilst speed and innovation play a vital part in adapting to new rules of conduct within retail, risk management is still a part of their project management tasks. The purpose of this thesis is to explore how management is working with handling risks that can occur in the transition processes to omnichannel. This thesis is based on a qualitative research design where seven semi-structured interviews have been conducted with managers from various large Swedish retail organizations. The conclusion shows three main themes from the empirical findings, which are the following: Operational risks are more common and manageable than strategical, Depending on project scope; risk assessment and mitigation differs and the diversity and roles of employees.

I find that not all the credit rating changes affect the market but only those classified as unanticipated. Subsequently, I study whether the regulatory setting, in which the Credit Ratings Agencies work, can possibly affect the financial markets reactions. Lastly I show that the probability of a future rating change is severely affected by different factors proportional hazard rate models.

Full textAbstract:
This research has reviewed the current status of offshore and marine safety. The major problems identified in the research are associated with risk modelling under circumstances where the lack of data or high level of uncertainty exists. This PhD research adopts an object-oriented approach, a natural and straightforward mechanism of organising information of the real world systems, to represent the Offshore Gas Supply Systems (OGSSs) at both the component and system levels. Then based on the object-oriented approach, frameworks of aggregative risk assessment and fault tree analysis are developed. Aggregative risk assessment is to evaluate the risk levels of components, subsystems, and the overall OGSS. Fault trees are then used to represent the cause-effect relationships for a specific risk in the system. Use of these two assessment frameworks can help decision makers to obtain comprehensive view of risks in the OGSS. In order to quantitatively evaluate the framework of aggregative risk, this thesis uses a fuzzy aggregative risk assessment method to determine the risk levels associated with components, subsystems, and the overall OGSS. The fuzzy aggregative risk assessment method is tailored to quantify the risk levels of components, subsystems, and the OGSS. The proposed method is able to identify the most critical subsystem in the OGSS. As soon as, the most critical subsystem is identified, Fuzzy Fault Tree Analysis (FFTA) is employed to quantitatively evaluate the cause-effect relationships for specific undesired event. These results can help risk analysts to select Risk Control Options (RCOs) for mitigating risks in an OGSS. It is not financially possible to employ all the selected RCOs. Therefore, it is necessary to rank and select the best RCO. A decision making method using the Fuzzy TOPSIS (FTOPSIS) is proposed to demonstrate the selection of the best RCOs to control the existing risks in the system. The developed models and frameworks can be integrated to formulate a platform which enables to facilitate risk assessment and safety management of OGSSs without jeopardising the efficiency of OGSSs operations in various situations where traditional risk assessment and safety management techniques cannot be effectively applied.

l July 2008, 105 pages Project Risk Management (PRM) comprises of identification and assessment, analysis and mitigation of risk factors in order to meet the project objectives. Risk identification and assessment process has the greatest importance as the risk models are constructed based on previously defined risk sources and their interrelations. Although previous studies have concentrated on the relation between risk events and their consequences, the link between them must be modeled by considering the various chains of risk events and the capacity of a &ldquo
system&rdquo
to react to risk events simultaneously. The concept of &ldquo
risk paths&rdquo
should be used to identify chains of risk events by means of a Hierarchical Risk Breakdown Structure (HRBS) rather than defining individual risk factors. The &ldquo
system&rdquo
consists of the characteristics of the project, company and involved parties. The word &ldquo
vulnerability&rdquo
is used to describe the degree v to which a project is susceptible to adverse effects of change. The aim of the current study is to develop a common vocabulary and design a HRBS that integrates vulnerability factors with risk factors. A generic risk and vulnerability assessment framework for international construction projects is presented in this research. The justification of the factors considered within the breakdown structure has been achieved by referring to real construction projects carried out by Turkish contractors in international markets.

Full textAbstract:
In today’s ever changing business landscape, technology and innovation projects play a key role in creating competitive advantages for an organisation. However, many such projects are often hampered by under performance, cost overruns and lower than predicted revenue (Morris and Hough, 1987 and Christoffersen et al, 1992). This seems to indicate the lack of risk management in the way we manage projects. On the other hand, it is impossible to have any projects without risks. Thus, it is essential to have effective risk management rather than trying to eliminate risk out of projects. These factors have guided this study to focus on understanding the way risk assessment is performed in international technology projects. It aims to identify the link between risk assessment and project categorization, drawing from the ransaction cost economics (TCE) perspective. A qualitative approach applying semi-structured interviews was conducted with ten interviewees holding different roles in the engineering and technology projects within a multinational company with presence in more than 100 countries around the world. The application of the data display and analysis technique by Miles and Huberman (1984, 1994) enables initial findings to be presented using the “dendogram” method, thereafter, leading to the development of a two-dimensional risk assessment matrix as the final result of this study.

The usage of information systems (IS) within organizations has become crucial. Information is one of the most vulnerable resources within an enterprise. Information can be exposed, tampered or made non-accessible, where the integrity, confidentiality or availability becomes affected. The ability to manage risks is therefore a central issue in enterprises today. In order to manage risks, the risks need to be identified and further evaluated. All kind of threats with the possibility to negatively affect the confidentiality, integrity, or availability of the organization need to be reviewed. The process of identifying and estimating risks and possible measures is called risk analysis. There are two main categories of risk analysis, qualitative and quantitative. A quantitative method involves interpreting numbers from data and is based on objective inputs. A qualitative method involves interpreting of subjective inputs such as brainstorming and interviews. A common approach is to apply a qualitative method, however a lot of criticism has been raised against using subjective inputs to assessing risks. Secure State is a consulting company with specialist expertise in the field of information security. They help their customers to build trust in the customers systems and processes, making their customers businesses operate with consideration to information security. One service offered by Secure State is risk analysis, and currently they perform qualitative risk analysis. Given all criticisms against a qualitative approach for assessing risks, this study developed a quantitative risk analysis method for Secure State. According to participants, who attended at a risk analysis where the developed quantitative risk analysis method was used, the quantitative risk analysis method improved the risk assessment. Since risks and their effects are decomposed into smaller components in the proposed quantitative risk analysis method, interpretations of risks and their meaning during assessments less likely differed. Therefore, the common understanding of a risk increases, which makes the quality of the evaluation of risks increase. Furthermore, the usage of statistical data increases in the developed quantitative risk analysis method. Additionally, the quantitative method handles the fact that all data used is imperfect. The data is imperfect since it is used to describe the future, and the future has not happened yet.

Many construction projects suffer from mismanagement despite continuous improvement in the field of project risk management. With the construction boom in the Middle East, and especially the Gulf region, construction projects suffer from a high failure rate. The lack of the implementation of standard risk management methods in the construction industry of the Gulf region leads to construction projects that suffer from poor performance, delays, disputes and claims. In order to design a standard risk management model, there is a need for an in-depth study of the construction environment to lay down the foundation for designing a Standard Construction Risk Management Model in the future. This study aims to identify and assess risk factors during the construction phase of construction projects in the Gulf region focusing on two countries of the Gulf region – the State of Kuwait and Kingdom of Bahrain. The risk factors (RF) were identified and assessed and responsiblty shares were allocated to construction parties: clients, consultants and contractors. The research strategy was a Sequential mixed-method. It was adopted by means of interview surveys followed by a questionnaire. The study started with a qualitative approach in which eleven practitioners were interviewed to evaluate and validate a questionnaire. This was followed by questionnaires distributed to a representative sample of 140 consultants, 128 contractors and 139 clients in the State of Kuwait, in addition to 71 consultants, 99 contractors and 78 clients in the Kingdom of Bahrain, to assess the negative impact of the risk factors during the construction phase on the completion of construction projects. Parametric tests were used to analyse the collected data. Including, the Analysis of Variance (ANOVA) test, the independent-samples t-test, and Pearson correlation coefficient (r) test. The study revealed a difference in perception of the risk factors negative impact on project completion between Kuwait and Bahrain, Bahrain perceives highest degree of impact on projects. On the categories level, both countries agreed on the Finance category as the main factor threatening project completion, and the External category as having the least impact. In Kuwait, almost all parties agreed on the negative impact of all categories on project completion except contractors who have different perception on management category. Furthermore, clients and consultants held different perceptions on the impact of design category. Bahrain results reveal significant differences in perceptions on the impact of categories between clients and the other parties, however there are slight differences between consultants and contractors in all categories. The limitations of the study include only large contractors and consultants in Kuwait and Bahrain were included in the study. The study was limited to the construction phase of construction projects and only six categories of risk factors were included in the study and This research was based on practitioners and participants opinions rather than actual occurrences on projects.
