Fire, Families and Decisions

Proudley, Mae Amber, mae.proudley@rmit.edu.au January 2009 (has links)
This research explores the life experiences of families and couples who lived through the Wangary fire (South Australia, January 2005). Examining the bushfire experience from a domestic perspective is long overdue. Open-ended interviews were conducted with thirty-eight couples and families across the fire-affected region on the Lower Eyre Peninsula. A shortlist of fourteen were analysed in detail and they form the foundation of this thesis. These bushfire narratives include the perspectives of farming and non-farming families and cover a wide spectrum of circumstances and demographics. Five of the fourteen families lost their homes in the Wangary fire. Critical decision-making and the presence of children is at the heart of this case study. How the presence of babies and young children influences family decision-making, in advance of or during a bushfire, has not been considered or studied in any detail within the Australian research landscape. Exploring the differences of experience between women with young families and older women confirms the primary weakness of the national bushfire safety ('stay or go') policy. Gender and generation were the two defining factors that informed how people responded to and recovered from the Wangary fire. The perspective of younger people, within the context of bushfire research, has been neglected in the past; this case study incorporates their views and thoughts. It is hoped that insights gleaned from these bushfire narratives will encourage the enhancement of the national 'stay or go' policy.

A VIEW INTO FUTURE POTENTIAL ICE THROW POLICIES AND THEIR EFFECT ON THE YIELD OF A VIRTUAL WIND FARM

Wild, de, Marc Noël January 2017 (has links)
There is a growth of wind power development in icing climates, in which ice accumulation on objects takes place. This leads to specific challenges including ice throw, the detachment of ice from wind turbine blades. The lack of understanding of the ice throw phenomenon among authorities leads to the fact that there is no coherence in the applied ice throw mitigation policies in various countries and regions, which can cause safety- and financial hazards for wind farms in icing climates. This research focusses on ice throw risk mitigation methods and their effect on a wind farms yield. Qualitative research is applied, interviewing six experts in the field of cold climate wind power development. The participants are from academic, public and private research institutions in five countries. The qualitative research focusses on policies that are plausible but non-preferred, as well as preference suggestions from the experts on how to treat the ice throw risks. The non-preferred policies involve shutting down wind farms during icing periods and conditionally allowed operation with applied heating systems. These policy scenarios are applied to a virtual wind farm near Slagnäs, Sweden, in order to indicate the impact on the yield and underline the impact that these policies would have on the turnover of a wind farm in a sever icing climate. The non-preferred policies have a significant impact on the Slagnäs wind farms yield with 2,28% annual yield losses in case of 200 annual icing hours. Apart from the impact on yield, the policies might not reduce the danger of ice throw significantly, as from a standing still turbine, detached ice can still travel a horizontal distance of up to one time the turbine height. Therefore, policies should according to the interviewed experts not focus on limitations, however focus on understanding risks and taking appropriate action for risk mitigation. International guidelines are the best tool to create a deeper understanding of ice throw risk assessments and their limitations, as well as an understanding of risk mitigation methods. In this case, the risk assessment process shall be standardised, however the risk mitigation methods shall be site specific.

Návrh bezpečnostní politiky české pobočky nadnárodní společnosti / The Proposal of a Safety Policy in the Czech Branch of an International Compan

Filip, Tomáš January 2009 (has links)
Safety policy deals with processes of security in company to protect assets regardless of a branch office size. Nowadays is the company exposed to a lot of threats and risks, which the company has to face to prevent work threats. This risks and threats don't have to be caused by competition, they can caused randomly, sporadically and someone can't be avoided or its protection is too expensive, whereas protection against some hazards can be easy or cheap. Analysis and appropriate safety actions are made for correct examination. This thesis put mind to create complete suggestion of safety policy for a small Czech branch of an international company. It contains required analyses, tips, theoretical solutions, policy for personal management and changes for easier suggestion of necessary safety documents. I made use of up-to-date information from the domain of security during the process, but special care has been made while writing the concepts, so that the document's contents wouldn't age so quickly.

Wazir Malik, Rashid January 2011 (has links)
The current research was a cross sectional research and was designed to assess the performance of the selected wind power company on compliance with health and management system OHSAS 1800:2007. One wind power company in Pakistan was selected for the research purpose. To collect quantitative data survey was conducted based on Questionnaire. For finding gaps within the existing practices and also for effectiveness of the research check list was designed. Questionnaires were distributed to the employees and one check list was given to the top management. The questionnaires were distributed randomly to the employees and out of fifteen questionnaires twelve were received back. After analyzing the data from the eleven questionnaires, the results shows that overall employees are 61 % strongly agree, 30 % agree, 2% disagree and 1% strongly disagree that the requirements of the system OHSAS 18001:2007 are met. 6% did not decide about it. The check list was received from top management after analyzing data from the check list results shows that top management of the subjected wind power organization is 74% strongly agree, 23% agree and 3 % undecided about the implementation of the system OHSAS 1800: 2007. From the results it can be concluded that both employees and top management of the subjected organization are agree with the fact that the H&S system OHSAS18001:2007 is being implemented well within the organization.

No. of bitstreams: 1 thesis_eduardo.pdf: 1968592 bytes, checksum: 33f7f4d5ebaf5f6c89601ef5078c74d5 (MD5) Previous issue date: 2018-05-25 / The first essay of this thesis, co-authored by Rodrigo Soares, develops a dynamic life-cycle equilibrium model of crime with heterogeneous agents and human capital accumulation. Public security policies are defined as pairs of a size of the police force and an average length of sentences. We propose an original micro-founded public security technology linking the level of police expenditures to the probability of arrest. This essay also contributes to the literature by proposing a dynamic equilibrium framework to evaluate public security policies. Equilibrium effects can be potentially relevant because of dynamic interactions between the classical incapacitation and deterrence effects. The model allows us to explore the optimality of policies in a way that would not be possible with reduced form empirical estimates or with the traditional, partial equilibrium, static, theoretical models of crime. We conduct an exploratory quantitative exercise calibrating the model to US property crime data from the 2000s. The calibrated model points to overspending in police protection and over incarceration in that period, when compared to the optimal public security policy. The second essay of this thesis develops a dynamic equilibrium model of crime with heterogeneous agents and several types of wrongs---actions that generate inefficiencies. Criminal codes define which wrongs are punishable by the state and penal codes define the length of the sentence if an agent is apprehended by the police committing a crime. %Agents decide at each point in time whether to commit crimes by comparing potential gains from crime to the expected loss due to the probability of apprehension and the associated cost (freedom deprivation). Criminal justice systems are defined as triplets of a criminal code, a penal code and a size of the police force. The dynamic framework with a multi-crime/multi-punishment setting, allows exploring substitution across different types of crime and might generate counter-intuitive results, mostly unexplored in the literature. The model developed in this essay also allows the endogenous definition of the set of actions that constitute crimes, as part of the welfare maximizing design of the criminal justice system. The third essay, co-authored by Braz Camardo, develops a 3-period model in which agents have time-inconsistent preferences and have access to an illiquid financial asset. The model developed in this essay studies the relationship between risk aversion and the demand for a commitment device, as represented by the illiquid asset. The main result is that, in an environment with uncertainty, a higher risk aversion implies a higher demand for the illiquid asset, due to a commitment motive. This counter-intuitive theoretical result is able to reconcile seemingly contradictory evidence found in the recent empirical literature. / No primeiro ensaio da tese, em coautoria com Rodrigo Soares, é desenvolvido um modelo dinâmico com equilíbrio e ciclo da vida com agentes heterogêneos e acúmulo de capital humano. Políticas de segurança pública são definidas como um par de gastos em força policial e tempo de pena. Neste ensaio, propomos uma tecnologia de segurança pública original e micro-fundamentada que permite que se expresse o nível de gastos com policiamento com a probabilidade de prisão. Este ensaio também contribui com a literatura ao usar um modelo dinâmico de equilíbrio capaz de avaliar políticas de segurança pública. Efeitos de equilíbrio podem ser potencialmente relevantes devido às interações dinâmicas entre os efeitos de dissuasão e incapacitação. O modelo permite a obtenção de políticas de segurança pública ótimas que seriam impossíveis de serem obtidas a partir de estimações que considerem apenas reduzidas, ou, ainda, a partir de tradicionais modelos estruturais de crime que levem em conta equilíbrio parcial ou que sejam estáticos. Por fim, este ensaio conduz exercícios quantitativos de calibração usando dados dos EUA da década de 2000. O segundo ensaio dessa tese desenvolve um modelo de equilíbrio dinâmico com agentes heterogêneos e vários tipos de ações que gerem externalidades negativas. Códigos criminais definem quais ações são consideradas como crime e, portanto, são puníveis pelo Estado e códigos penais definem o tempo de pena médio para cada crime. Sistemas de justiça criminal são definidos como a tripla de códigos criminais, códigos penais e gastos em policiamento. O ambiente dinâmico com muitos tipos de crimes e punições permite que se explore efeitos de substituição entre diferentes tipos de crime, o que pode levar a resultados contra-intuitivos que ainda não foram explorados pela literatura. Por fim, os componentes deste modelo permitem uma definição endógena do conjunto de ações que deveriam ser consideradas como crime, já que a definição do código criminal pode ser escolhida de forma a maximizar o bem-estar social. O terceiro ensaio, em coautoria com Braz Camargo, considera um modelo com três períodos em que agentes são temporalmente inconsistentes e possuem acesso a ativos ilíquidos. Este modelo estuda a relação entre aversão ao risco e demanda por mecanismos de comprometimento, representada por um ativo ilíquido. O principal resultado é que, em um ambiente com incerteza, uma maior aversão ao risco maior implica uma demanda maior por ativos ilíquidos. Este resultado teórico contra-intuitivo é capaz de conciliar resultados aparentemente contraditórios da literatura empírica.

An analysis of patterns and trends of road traffic injuries and fatalities in Vhembe District, Limpopo Province, South Africa

Osidele, Olujimi Agbolahan January 2016 (has links)
MENVSC / Department of Geography and Geo-Information Sciences / Road transport safety is challenging globally, especially in developing countries, where it affects both road users and governments. The aim of road traffic safety is to ensure a reduction or total eradication of road fatalities and other injuries that are related to road accidents resulting from public road usage. In South Africa, one of the major problems faced by the Department of Roads and Transport is the issue of road traffic accidents. Between 2004 and 2010 the annual road traffic accidents increased to over 500,000 and 28,000 or more are fatal, which has led to serious injuries, as reported by the Department. This study analysed patterns and trends of road traffic injuries and fatalities in Vhembe District Municipality from January 2011 to August 2015. It also mapped road accident hotpots using Getis hotspot analysis and linear referencing in ArcGIS 10.2 spatial statistics extension. The research further established correlation between accidents spots and road design geometry. Factors that are responsible for road traffic accidents leading to fatalities, injuries, and loss of property were also examined. Pedestrian behavioural attitude towards adhering to road safety measures was studied using systematic random sampling, field observation and questionnaires. Finally, the study investigated if there has been any significant reduction in the road traffic injuries and fatalities occurrence rate within the last five years in Vhembe District since the commencement of World Health Organisation; Decade of Action for Road Safety 2011-2020. It was found out that most of the accidents occurred as a result of changes in human social behaviour, negligence and indulgence. The passenger road users category is the worst affected followed by drivers and pedestrians. It was found out that road crashes have decreased by 35% since the commencement of decade of action for road safety. The composition of road traffic injuries and fatalities since 2011 shows a reduction in the numbers of victims recorded. An average of 86 fatalities, 326 serious injuries and 701 minor injuries occurred per annum within the study period. There was high significant value (p  0.05) among all the categories of road users understudied. The differences observed were real and did not occurred by chance for the 5year period (2011 – 2015).

Essays on Sparse-Grids and Statistical-Learning Methods in Economics

Valero, Rafael 07 July 2017 (has links)
Compuesta por tres capítulos: El primero es un estudio sobre la implementación the Sparse Grid métodos para es el estudio de modelos económicos con muchas dimensiones. Llevado a cabo mediante aplicaciones noveles del método de Smolyak con el objetivo de favorecer la tratabilidad y obtener resultados preciso. Los resultados muestran mejoras en la eficiencia de la implementación de modelos con múltiples agentes. El segundo capítulo introduce una nueva metodología para la evaluación de políticas económicas, llamada Synthetic Control with Statistical Learning, todo ello aplicado a políticas particulares: a) reducción del número de horas laborales en Portugal en 1996 y b) reducción del coste del despido en España en 2010. La metodología funciona y se erige como alternativa a previos métodos. En términos empíricos se muestra que tras la implementación de la política se produjo una reducción efectiva del desempleo y en el caso de España un incremento del mismo. El tercer capítulo utiliza la metodología utiliza en el segundo capítulo y la aplica para evaluar la implementación del Tercer Programa Europeo para la Seguridad Vial (Third European Road Safety Action Program) entre otras metodologías. Los resultados muestran que la coordinación a nivel europeo de la seguridad vial a supuesto una ayuda complementaria. En el año 2010 se estima una reducción de víctimas mortales de entre 13900 y 19400 personal en toda Europa.
