The use of a risk based approach to identify the uncertainties associated with flooding of highway drainage infrastructure

Barnett, Sally Jillian Anthony January 2016 (has links)
The strategic and local road networks are together the United Kingdom’s most valuable infrastructure assets. Roads deteriorate over time as a function of traffic and the environment and must be maintained appropriately to preserve their asset value in order to help support the economy. Furthermore, well maintained roads reduce road user costs via lowering vehicle operating costs, reducing accidents, delays and litigation. Amongst other projections, climate change indicators suggest there will be warmer wetter winters and an increase in extreme weather events such as heavy rains. Increased heavy rainfall events will adversely influence the road infrastructure and place more demands on maintenance. The inherent risks in highway infrastructure assets and those associated with future climate predictions must be better understood and incorporated within decision support models to enable highway engineers and asset managers make better, more informed decisions regarding infrastructure maintenance. By combining the risk management process and drainage network analysis this study explored the risks and their potential impacts within a road network. This resulted in a proposed methodology for the identification of parts of a network to be most at flood risk. Data in respect of the risks and their probability of occurrence, for use within the model was obtained through a questionnaire completed by highway drainage engineers at various locations in the UK.

Legal translation and terminology in the Irish Free State, 1922-1937

McGrory, Orla January 2018 (has links)
This thesis explores the role and impact of Rannóg an Aistriúcháin - the Oireachtas Government Translation section - on English-Irish legal translation and terminology, with particular focus on the period 1922-1937; a period bookended by the establishment of the Irish Free State and the enactment of Bunreacht na hÉireann (the Constitution of Ireland) in 1937. It aims to assess the efficacy and consistency of the translation strategies and Irish legal terms employed by Rannóg an Aistriúcháin, and to investigate how modern translation theory – specifically equivalence theory – may be applied to English-Irish legal translation as a whole. While a semantic study of the English and Irish versions of the amended 1937 Constitution has previously been carried out (Ó Cearúil, 1999), there has yet to be any specific study of other translated English-Irish legislative material within the Irish Free State or, indeed, of any laws translated within the Rannóg. This is an area which holds great research potential as regards assessing the efficacy of a particular body of translations, as the position of the Irish language in the Republic of Ireland is a unique one. Not only is Irish an official language of the European Union, but it enjoys constitutional status as the National and First Official language of the Republic of Ireland, with Article 25.4.6o of the Irish Constitution 1937 providing that: ‘In case of conflict between the texts of a law enrolled under this section in both the official languages, the text in the national language shall prevail’. In other words, should the Irish translation deviate in any way from its English legislative counterpart, it is the Gaelic translated legislation - along with all its construed connotations and associations - which has the upper hand. With this reasoning in mind, this thesis takes a corpus of EN-GA legislative material translated by Rannóg an Aistriúcháin during the period 1922-1937, from which legal terms are chosen for analysis and qualitatively and semantically assessed in the context of Equivalence translation theory and legal translation. Ultimately, this thesis provides a new critical assessment of the reliability of Irish language legal terminology in primary legislation from this period; an analysis of how Equivalence theory may be applied to EN-GA legal translation as a whole; and provides some guidelines for future endeavours in English-Irish legal translation and terminology.

Gestion de l'incertitude et codage des politiques de sécurité dans les systèmes de contrôle d'accès / Managing uncertainty and encoding security policies in access control systems

Bouriche, Khalid 16 February 2013 (has links)
La présente thèse s'intéresse à coder la politique de sécurité SELinux en OrBAC et à proposer une extension de ce modèle. Nous avons commencé par présenter l'état de l'art des différents modèles de contrôles d'accès présents dans la littérature en mettant en exergue les limites de chacun de ces modèles. Ensuite nous avons présenté le modèle OrBAC comme étant une extension du modèle RBAC, car d'une part il a apporté la notion de contexte et d'organisation et d'autre part il permet d'exprimer, en plus des permissions, des interdictions et des obligations. Ensuite, nous avons présenté la solution de sécurité SELinux qui utilise un ensemble de modèles de contrôle d'accès comme DAC, RBAC et MAC. Nous avons recensé plusieurs centaines, voire des milliers, de règles dans la politique de sécurité SELinux, ces règles peuvent concerner des décisions d'accès ou des décisions de transition. Nous avons ensuite pu coder lesdites règles en modèle OrBAC, et ce en passant par le remplissage ses tables d'entité, pour ensuite les transformer en relations OrBAC. Notre thèse a aussi rappelé les fondements de la logique possibiliste, et a ensuite apportée une amélioration importante du modèle OrBAC, il s'agit de l'introduction de l'entité priorité au niveau de chaque relation du modèle OrBAC. L'entité priorité quantifie la certitude pour qu'une entité concrète soit injectée dans l'entité abstraite correspondante, ou en cas général, le degré de certitude pour qu'une relation soit réalisée. Nous avons proposé trois modes de combinaison (pessimiste, optimiste et avancé) qui peuvent être adoptés pour déterminer la valeur de la priorité de chaque relation concrète à partir des priorités des relations abstraites correspondantes. Enfin, nous avons implémenté, via une application développé par DELPHI, le codage des règles concernant les décisions d'accès de la politique de sécurité SELinux, en modèle OrBAC tout en introduisant la notion de priorité. / This thesis focuses on encoding default-based SELinux security policy in OrBAC and propose an extension of this model. We presented the state of the art of different models of access controls present in the literature underlining the limitations of each of these models. Then we presented the model OrBAC as an extension of the RBAC model, firstly because he brought the notion of context and organization and secondly it allows expressing, in addition to permissions, prohibitions and obligation. Then we presented the SELinux security solution that uses a set of access control models such as DAC, RBAC and MAC. We identified several hundreds or even thousands of rules in SELinux security policy, these rules may be access decisions or decisions of transition. We could then encode these rules in OrBAC model, and via filling its tables of entities, then transform relations OrBAC. Our thesis also reviewed the foundations of possibilistic logic, and then made an important enlargement in OrBAC model; it's to introduce an entity called "priority" in each relationship model OrBAC. The entity "priority" quantifies the certainty for concrete entity injection into the corresponding abstract entity, in general, it's meaning the degree of certainty that a relationship is performed. We proposed three modes of combination (pessimistic, optimistic and advanced) that can be adopted to determine the concrete relations priority value from priorities values of each corresponding abstract relationship. Finally, we implement, via an application developed by DELPHI, coding access decisions rules of the SELinux policy in OrBAC model introducing the priority entity.

Geometria, Estabilidade e Estrutura Eletrônica das Superfícies GaAs(001): Te e InAs(001): Te / Geometry, stability and electronic structure of GaAs surfaces (001): Te and InAs (001): Te

Roberto Claudino da Silva 20 March 1998 (has links)
Estudamos a adsorção de Te em superfícies de GaAs(001) e InAs(001) com periodicidades 1x1, 1x2, 2x1 e 2x2, para as concentrações de telúrio Tc= 0, 1/4, 1/2, 3/4 e 1. Realizamos cálculos dentro do formalismo do funcional da densidade empregando pseudopotenciais de norma conservada. Para a relaxação das estruturas empregamos a dinâmica molecular de Car e Parrinello. Nossos resultados apontam para uma redução na estabilidade das superfícies na proporçã em que aumenta a concentração de Te na uperfície. A cobertura de As (Tc = 0) é energeticamente mais favorável que as recobertas com qualquer concentração de Te, tanto na superfície de GaAs(001) quanto na de InAs(001). Observouse ainda nas superfícies com Tc = 0 Tc = 1, que a dimerização dos átomos de As e da ordem de 30% mais intensa que dos átomos e Te. Comparando as dimerizações do Te nas superfícies com concentrações Tc 1/2, observamos que elas são maiores sobre o InAs(001) (célula terminada em In) que sobre o GaAs(001) terminada em Ga). Outra tendência verificada e a \"flutuação\" do Te sobre as superfícies. Para uma mesma concentração verificamos a \"preferência de adsorção\" em sítios fora da cadeia de dímeros indicando uma adsorção monoatômica. Para concentração Tc = 1 na superfície GaAs(001):Te2x2 observamos duas geometrias possíveis: uma com cadeias de dímeros seguindo o modelo \"dimerrowmissing\" e outra com dois tipos de dímeros em posições alternadas ao longo da dir~ao (110). Analisando as energias de adsorção nas duas superfícies verificamos que a adsorção sobre o InAs é mais favorável que sobre o GAs. Analisamos ainda a estrutura eletrônica das superfícies em todas as reconstruções e concentrações consideradas e verificamos anda o caráter semicondutor das superfícies com concentração Tc = 1/2. / We have carried out ab initio density functional calculations to investigate the adsorption of Te on GaAs(001) and lnAs(001) surfaces as a function of Te surface coverage: Tc = 0, 1/4, 1/2, 3/4, 1. In order to determine the equilibrium atomic positions, the geometry was relaxed according he calculated total energy and forces following the Car Parrinello approach for molecular dynamics. Our calculations indicate that a full monolayer of As (Tc = 0) is energetically more favourable than any of the studied coverage of Te (Tc = 1/4, 1/2, 3/4, 1), where the stability is educed with increasing Te coverage. The dimerization of surface As atoms is about 30% more intense than surface Te atoms. Comparing the Te dimerization on InAs(001), In terminated, and aAs(OOI), Ga terminated, we observed that the Te atoms dimerize more over lnAs than GaAs surface. Another observation is the tendency of the Te atoms to \'l1oat\" from the surface with increasing coverage. For the same concentrations of Te the atoms \"prefer\" to be adsorbed on the offchain sites indicating a monoatomic adsorption. The adsorption energy of Te on InAs(001) is more favorable than GaAs(001). We also determined the surface band structure for all reconstructions and Te concentrations, veryfying the semiconductor nature for Tc = 1/2.

Climate change and road freight safety : impacts and opportunities

Jaroszweski, David John January 2010 (has links)
This thesis aims to apply recent conceptual frameworks for climate change impact assessment to the road freight sector of Great Britain in order to identify potential future safety issues. The freight sector is a key component of Great Britain’s economy, and one which is particularly vulnerable to the effects of adverse weather. An assessment of the current patterns in weather related freight accidents is produced, and existing studies on accident causation are elaborated upon to arrive at relationships between key meteorological parameters and freight accident rates. These relationships are extrapolated onto various climate scenarios under low, medium and high emissions for the 2020s, 2050s and 2080s using UKICP09 climate tools to arrive at projections of possible impacts at a regional scale. This thesis also addresses a key criticism of the previous climate change impact assessment literature; that studies usually neglect the consideration of what the network will look like in the future, how it will be used, and how this will impact upon its vulnerability to meteorology. The way in which the network is designed, the resilience of the vehicles that operate on it and the split of usage between the various modes will all affect the impacts that are likely to be seen, and are all determined by the broader socio-economic pathway of the country. Delphi techniques are used for short term forecasts of growth and to identify emerging issues with the industry. UKCIP data is used to extend these projections to 2050. By combining social and physical techniques, a more holistic picture of future impacts is found. Although the confluence of safer technology and a reduction of winter road icing and summer precipitation events could potentially lead to a safer operating environment, certain scenarios which promote high emissions, a larger freight fleet and low investment in infrastructure could cause problems, especially for winter precipitation events.

Using Lao Tzu’s Tao Te Ching to cultivate a Classical performing musician’s professional mindset

Chiou, Jing-Fu Jeffrey 01 August 2018 (has links)
This thesis reaches across multiple disciplines, including music psychology, performing arts, and philosophy, to propose using Lao Tzu’s philosophical thoughts in his book Tao Te Ching (also Dao De Jing, daodejing) to cultivate a classical performing musician’s “professional mindset.” “Professional mindset” is defined as the performer’s attitude in dealing with people including himself, and philosophical perspectives in making music. Part I evaluates the recurring traits of classical performing musicians (CPMs) as key for later arguing that Tao Te Ching helps enhance and transform the associated behaviors of a CPM’s recurring traits. These traits include being aloof, intelligent, emotionally unstable, dominant, sensitive, imaginative, self-sufficient, having high ergic tension, along with the associated second-order factors introversion, anxiety, independence, and being unrestrained. Part II introduces Tao Te Ching by building its thinking system map, with each of the book’s components explained and the underlying concepts hidden in the map uncovered via my English translations of the text as found in Chen Guying’s commentary. Part III presents three perspectives that collectively argue how Tao Te Ching cultivates a CPM’s professional mindset. The first analyzes anecdotes from the biographies of flutist Marcel Moyse using the recurring traits of CPMs in order to show how Lao Tzu’s thoughts can enhance or transform the associated behaviors of the recurring traits of CPMs. The second philosophically applies the duality of Lao Tzu to a CPM’s main musical activities and defines his daily performing cycle. The third explains how Tao Te Ching creatively deals with musical matters.

Heteronormativity and early childhood education: Social justice and some puzzling queries.

Gunn, Alexandra Claire January 2008 (has links)
This thesis investigated the discursive production of heteronormativity in the historical and present day contexts of early childhood education in Aotearoa New Zealand. A Foucauldian genealogical investigation of early childhood policy and documents revealed how heteronormative discourses shaped understandings in early childhood education in the twentieth century. Then a study of practices as accounted for and produced in focus group interviews showed how heteronormative discourses were confirmed and resisted in the present day. The thesis argues that the locus of heteronormativity in early childhood education centres on constructions of the family, of genders and of sexualities. It sought to investigate whether heteronormative discourses were shaping practices in early childhood education, and if so how. Following the writing of a genealogy of heteronormativity in early childhood education, the fieldwork of the study entailed three rounds of focus group interviews with queer teacher, queer ally and teacher educator participants. Discussions in the interviews were provoked by dilemmas of heterosexism, homophobia and heteronormativity in early childhood settings. Participants were asked to talk about what they thought was occurring in the dilemmas and they were also asked to share examples of practices from their own professional lives where same-sex sexualities had been troubled or affirmed. The texts produced from the focus group interviews were read the same way as the historical and policy and documents. Foucault's discourse analysis combined with questions from Davies' (1994) study of teaching practices, and queer theory provided a theoretical framework through which I was able to explore relations between constructions of genders, families, and sexualities; concepts of insiders and outsiders; and notions of power. A queer turn in the project enlarged the focus of the study to investigate how heteronormative discourse might have been shaping the research interviews too. A discourse of silence along with a discourse of risk was interpreted as contributing to heteronormativity in this work. A strategy designed to assist teachers to interrupt heteronormativity was explored. It allowed teachers to bring together ideas and concepts that would constitute families and parents in ways inclusive of and broader to the (hetero)norm. In the study, teachers, children and parents were shown to draw on (hetero)normalising discourses in their interactions with each other in early childhood education. Such activity limited opportunities for valid alternative options to heterosexuality to be known. This meant that heterosexuality was repeatedly constituted as dominant and normative, thus supporting heteronormativity. Constructions of genders, families and sexualities in the study were regularly shaped by traditional and essentialising discourses that positioned heterosexual sexuality as normal and non-heterosexual sexualities as not. These in combination with other discourses, such as a discourse of developmentalism, provided few opportunities for non-heterosexual sexualities to be recognised, valued and included in early childhood education. The extent to which socially just and inclusive policy aims in early childhood education might therefore be met in practice, could be seriously questioned. However, examples of practices that worked to expand opportunities for the recognition of diverse families and sexualities in early childhood education were also documented. These provided evidence that some teachers, parents and children in some circumstances can and do access and use discourses of social justice, family and sexual diversity, inclusion and human rights. Sustained access to these was not documented, in fact, discourses of social justice, family and sexual diversity, and inclusion were often immediately countered by limiting and (hetero)normalising responses. The thesis concludes with suggestions as to how such processes might be explored and challenged so that more teachers, more children, more families can enjoy recognition and welcome in early childhood education settings designed to include.

Kimihia, rangahaua ngā tikanga heke iho. He taonga huahua e riro mai: Exploring whakapapa as a tool towards a kaupapa Māori assessment framework in early childhood education

Paki, Vanessa Anne January 2007 (has links)
This study explores whakapapa as a tool, which can be used as a kaupapa Māori assessment framework in early childhood education, positioning kaupapa Māori theory as a paradigm base underpinning a philosophical and theoretical discourse towards assessment for children's learning. This thesis represents the culmination of a personal and professional journey, derived from the writer's longstanding interest in and commitment to kaupapa Māori early childhood education, and more specifically, philosophies and practices for assessment in this context. The study has canvassed a vast terrain of kaupapa Māori philosophy in its search for a theoretical grounding for a kaupapa Māori assessment framework for early childhood education. Foundation to the study has been the premise that the notion of whakapapa serves as an overarching philosophical matrix, encompassing the interconnected realms of genealogy, spirituality, and knowledge that precede, surround, and embrace the Māori child. Throughout the thesis, diagrams are employed to demonstrate and model the whakapapa underpinning the conceptualisations being explored. After contextualising the study within a historical overview of the impact of colonisation of kaupapa Māori education and research, it is suggested that a re-examination of key concepts from tikanga Māori will illuminate transformative possibilities applicable to the study's focus on the development of a theoretical base for an assessment tool within kaupapa Māori early childhood settings. Drawing from the literature, the thesis re-positions the view of the Māori child to one of being nurtured within a philosophical construct underpinned and immersed in tikanga such as whakapapa, ira tangata, whanaungatanga, mana and tapu, and ako, providing a strongly Māori theoretical base for the envisioning of the assessment process. The outcome of this study is to propose an assessment framework, which embodies and reflects these core kaupapa Māori philosophies as praxis.

The impact on Hamilton Abuse Intervention Project of government policy changes-an investigation

Haley, Caryl Rosemary January 2008 (has links)
This research investigates the perceptions and viewpoints of staff working for the Hamilton Abuse Intervention Project (HAIP) as to the impact of changes in government policy. Established in 1991 HAIP is a coordinated community response to domestic violence based on the Duluth Model. Over the last two decades governments in New Zealand have introduced policies and strategies to combat violent crime in the community predicated on the understanding that addressing violence within the family/whanau setting will assist in breaking the cycle. This research focuses on the impact of strategies which advocated inter-agency collaboration such as the VIP Pol400 Project (Pol400 Project) established in 2001 with HAIP as the lead agency. (VIP is an abbreviation standing for Violence Intervention Project). The research also set out to test the hypothesis that working within an environment marked by the introduction of policy changes and new strategies has a significant impact upon a social services agency such as HAIP. In view of the inherent complexity of investigating perceptions and viewpoints qualitative methodology was chosen for this research. Ten of the fourteen people employed by HAIP contributed to the research. Semi-structured face to face interviews and the written answers from questionnaires provided a detailed body of information which informed the narrative and descriptions of this study. An outline of relevant legislation, policy initiatives and strategies introduced over the last two decades was provided to give a framework for the study. Each of the respondents commented on issues related to funding and workload. Inadequate funding was seen to be adding to already heavy workload which continued to grow aggravated by the demands of compliance and accountability. Respondents identified some aspects of HAIP which had been affected by lack of adequate funding such as the loss of the 24/7 Crisis Line and difficulties with maintaining the parallel development policy. However, In spite of funding shortfalls respondents noted that HAIP's services continued to expand and examples were given of recent initiatives such as the establishment of home support groups. Several respondents identified the Pol400 Project as being significant development in HAIP's services. Respondents commented on its value in closing gaps in the criminal justice system's response to incidents of family violence. A detailed analysis of the Pol400 Project using archival material and using statistics from the HAIP Pol400 database demonstrated the comprehensive extent of the inter-agency collaboration. The findings of this investigation showed that respondents regarded inadequate funding and increased workload as impacting significantly on their work. However, apart from comments made in relation to some negative impacts on HAIP of the Domestic Violence Act of 1995, respondents rarely made a specific connection between these issues and their relationship to changes in government policies. This study showed that since the Pol400Project began in 2001 reported incidents of family violence and subsequent referrals rose steadily but the data showed a marked increase in activity following the involvement in 2005 of a Family Safety Team. The increase in the intake of reports was attributed, in part, to the police addressing gaps and shortfalls in their own systems. The impact of the Pol400 Project on HAIP was seen, in the main, to be contributing positively to HAIP's role in providing a seamless coordinated community response to family violence.
