Full textAbstract:
Aim: The overall aim of this thesis was to describe and explore the use and content of ICU-diaries and to develop and psychometrically test a questionnaire to detect physical and psychosocial problems for ICU patients in their recovery process. Methods: This thesis is based on four studies. Study I had an explorative descriptive design with a quantitative and qualitative approach. Data were collected by telephone interviews with staff at Swedish ICUs (n = 65) which kept ICU-diaries. One question “what was the purpose of keeping ICU-diaries” was analysed with latent content analysis, and the other data were analysed with descriptive and comparative statistics. Study II had an explorative descriptive cohort design with a concurrent mixed method approach. The sample in study II was a part of the sample in study IV in which 421 former ICU patients responded to a new developed questionnaire 3-set 4P two months after discharge from ICU. Patients from this sample who have had an ICU-diary (n = 115) responded to a questionnaire six months after discharge from ICU. Fifteen patients were interviewed about the content and usefulness of the ICU-diary. Data were analysed with descriptive statistics, descriptively by content and interviews with manifest content analysis and then combined at the interpretive level to seek convergence, as enable by the mixed method approach. Study III had a methodological design. In this study, the questionnaire 3-set 4P was developed and psychometrically tested in a pilot setting. In study IV, the questionnaire was further developed and tested based on psychometric evaluation of the 3-set 4P. In study III the questionnaire was responded by 39 patients and in study IV by 421 patients. Data in study III and IV were analysed with descriptive statistics and psychometrical tests. Results: The main purpose for keeping ICU-diaries was to provide a tool in the recovery by helping the patient remember and give time back. Keeping ICU-diaries was common although there was a difference in practice and patient recruitment among different hospitals (study I). An ICU-diary with content and photos in a chronological order describing the whole picture of critical illness and ICU stay could be a tool for the patient to construct a coherent individual story. The ICU-diary could be one piece to give a deeper understanding and meaning in the personal story and to give a realistic expectation of the recovery process. Absence of guidelines for keeping ICU-diaries could affect the possibility for the ICU-diary to be a helpful tool during the recovery process (study II). In study III, the 3-set 4P was developed to be used for identifying and evaluating former ICU patients’ physical, psychosocial problems and outcome during follow-up. The psychometrical tests showed acceptable validity and internal consistency reliability. The stability reliability was acceptable in two of three sets. The psychometrical tests of the further modified version of 3-set 4P in study IV showed good construct validity and internal consistency but it needs some modification before it can be used in clinical practice (study IV). Conclusion: Recovery can be a difficult process where different tools can be useful. Today there is no evidence about tools to use during follow-up. To promote high quality of the follow-up there is a need for evidence-based guidelines. The ICU-diary is one tool but this thesis shows that guidelines for keeping ICU-diaries have to be developed to meet the patients’ wishes in order for the ICU-diary to become a useful tool during the process to recovery. The 3-set 4P can after some modification be used at the follow-up clinic to identify the individual patient’s problems and create an individual program for recovery.

Problem: What are the most useful techniques to indicate the stocks that will outperform the market 12 month post the recession period? Purpose: The purpose is to find out which method(s): P/B, EV/EBIT, level of debt and so on, will offer investors the highest returns on the investments post the recession period based on the example of the IT crisis of 2000/2001. Method: Quantitative study, covering the Swedish OMX Index from 2001 until December 2002. Conclusions: Three variables should be reconsidered when making an investment decision post the recession period. These variables were earlier 12 months returns, dividend yield and P/E ratios. However, it is crucial to understand that these three tools should not be viewed all together.

Brown, Daniel. "The use of geospatial tools to support, monitor and evaluate post-disaster recovery." Thesis, University of Cambridge, 2018. https://www.repository.cam.ac.uk/handle/1810/274920.
Full textAbstract:
The aim of this research is to test the feasibility of using remote sensing-based information products and services to support the planning, monitoring and evaluation of recovery after disaster. The thesis begins by outlining the process of post-disaster recovery, what it entails and who is involved. The data and information needs at different stages of the disaster cycle are introduced and the importance of monitoring and evaluating post-disaster recovery is discussed. The literature review introduces the high-spatial-resolution remote sensing market and the technology focusing on current sensors’ capabilities. This is followed by a review of previous attempts to measure post-disaster recovery by practitioners and academics. At the end of the chapter a list of recovery indicators, suitable for remote sensing analysis, are presented and assessed through a user needs survey. In chapter 3, the six recovery categories and thirteen indicators identified in the literature review form a framework for the retrospective analysis of recovery in Thailand and Pakistan. A selection of results is presented to demonstrate the usefulness of remote sensing as a recovery monitoring tool. To assess its reliability, the results from the satellite image analysis are triangulated against narratives and datasets acquired on the ground. The next two chapters describe work done whilst providing real-time support to two humanitarian agencies operating in Port-au-Prince one-and-a-half years after the 2010 Haiti earthquake. Chapter 4 describes how geospatial tools were used to support a British Red Cross integrated reconstruction project for 500 households living in an informal settlement. The chapter describes how geospatial tools were used as a rapid assessment tool, and to support cadastral and enumeration mapping and the community participatory process. While previous chapters focus on the manual analysis of satellite imagery, chapter 5 reports how semi-automatic analyses of satellite imagery were used to support UN-Habitat by monitoring a planned camp and large-scale instances of spontaneous settlement. The conclusion to the thesis summarises the key lessons learnt from the retrospective analysis of recovery in Thailand and Pakistan and the real-time application in Haiti. Recommendations are then made on how to effectively use remote sensing in support of post-disaster recovery focussing on what to measure, when and how. Recognising that a mixed-method approach can best monitor recovery, recommendations are also made on how to integrate remote sensing with existing tools.

Petersen, Sara L. "Eating Disorder Risk Among Males in Substance Abuse Recovery| A Comparison of Two Survey Evaluation Tools." Thesis, California State University, Long Beach, 2017. http://pqdtopen.proquest.com/#viewpdf?dispub=10264684.
Full textAbstract:
Individuals with co-occurring substance use disorders (SUD) and eating disorders (ED) are at increased risk for poor treatment outcomes. Therefore, proper screening for EDs is essential within SUD treatment facilities. Standard ED screening tools have only been validated on females. Eating disorder symptomology often presents differently in males demonstrating the need for a male specific ED screening tool. This need has been addressed in the preliminary screening tool, Eating Disorder Assessment for Males (EDAM). The purpose of this study is to compare the outcome of two ED screening tools, EAT-26 and EDAM, among males in SUD treatment, specifically to evaluate the level of agreement between the surveys.
No significant correlation exists between the EDAM’s muscle dysmorphia component and EAT-26. Preoccupation with muscularity is a distinct characteristic of ED symptomology among males. The muscle dysmorphia component is a unique element within EDAM, illustrating the need for male specific ED screening tools.

Full textAbstract:
This report aims to draw a comparison between two commercial mobile forensics and recovery tools, Magnet AXIOM and MOBILedit. A thorough look at previously done studies was helpful to know what aspects of the data extractions must be compared and which areas are the most important ones to focus upon. This work focuses on how the data extracted from one tool compares with another and provides comprehensive extraction based on different scenarios, circumstances, and aspects. Performances of both tools are compared based on various benchmarks and criteria. This study has helped establish that MOBILedit has been able to outperform Magnet AXIOM on more data extraction and recovery aspects. It is a comparatively better tool to get your hands on.

Full textAbstract:
Exploitation of waste heat could achieve economic and environmental benefits, while at the same time increase energy efficiency in process sites. Diverse commercialised technologies exist to recover useful energy from waste heat. In addition, there are multiple on-site and offsite end-uses of recovered energy. The challenge is to find the optimal mix of technologies and end-uses of recovered energy taking into account the quantity and quality of waste heat sources, interactions with interconnected systems and constraints on capital investment. Explicit models for waste heat recovery technologies that are easily embedded within appropriate process synthesis frameworks are proposed in this work. A novel screening tool is also proposed to guide selection of technology options. The screening tool considers the deviation of the actual performance from the ideal performance of technologies, where the actual performance takes into account irreversibilities due to finite temperature heat transfer. Results from applying the screening tool show that better temperature matching between heat sources and technologies reduces the energy quality degradation during the conversion process. A ranking criterion is also proposed to evaluate end-uses of recovered energy. Applying the ranking criterion shows the use to which energy recovered from waste heat is put determines the economics and potential to reduce CO2 emissions when waste heat recovery is integrated in process sites. This thesis also proposes a novel methodological framework based on graphical and optimization techniques to integrate waste heat recovery into existing process sites. The graphical techniques are shown to provide useful insights into the features of a good solution and assess the potential in industrial waste heat prior to detailed design. The optimization model allows systematic selection and combination of waste heat source streams, selection of technology options, technology working fluids, and exploitation of interactions with interconnected systems. The optimization problem is formulated as a Mixed Integer Linear Program, solved using the branch-and-bound algorithm. The objective is to maximize the economic potential considering capital investment, maintenance costs and operating costs of the selected waste heat recovery technologies. The methodology is applied to industrial case studies. Results indicate that combining waste heat recovery options yield additional increases in efficiency, reductions in CO2 emissions and costs. The case study also demonstrates that significant benefits from waste heat utilization can be achieved when interactions with interconnected systems are considered simultaneously. The thesis shows that the methodology has potential to identify, screen, select and combine waste heat recovery options for process sites. Results suggest that recovery of waste heat can improve the energy security of process sites and global energy security through the conservation of fuel and reduction in CO2 emissions and costs. The methodological framework can inform integration of waste heat recovery in the process industries and formulation of public policies on industrial waste heat utilization.

Steinert, Bastian. "Built-in recovery support for explorative programming : preserving immediate access to static and dynamic information of intermediate development states." Phd thesis, Universität Potsdam, 2014. http://opus.kobv.de/ubp/volltexte/2014/7130/.
Full textAbstract:
This work introduces concepts and corresponding tool support to enable a complementary approach in dealing with recovery. Programmers need to recover a development state, or a part thereof, when previously made changes reveal undesired implications. However, when the need arises suddenly and unexpectedly, recovery often involves expensive and tedious work. To avoid tedious work, literature recommends keeping away from unexpected recovery demands by following a structured and disciplined approach, which consists of the application of various best practices including working only on one thing at a time, performing small steps, as well as making proper use of versioning and testing tools.
However, the attempt to avoid unexpected recovery is both time-consuming and error-prone. On the one hand, it requires disproportionate effort to minimize the risk of unexpected situations. On the other hand, applying recommended practices selectively, which saves time, can hardly avoid recovery. In addition, the constant need for foresight and self-control has unfavorable implications. It is exhaustive and impedes creative problem solving.
This work proposes to make recovery fast and easy and introduces corresponding support called CoExist. Such dedicated support turns situations of unanticipated recovery from tedious experiences into pleasant ones. It makes recovery fast and easy to accomplish, even if explicit commits are unavailable or tests have been ignored for some time. When mistakes and unexpected insights are no longer associated with tedious corrective actions, programmers are encouraged to change source code as a means to reason about it, as opposed to making changes only after structuring and evaluating them mentally.
This work further reports on an implementation of the proposed tool support in the Squeak/Smalltalk development environment. The development of the tools has been accompanied by regular performance and usability tests. In addition, this work investigates whether the proposed tools affect programmers’ performance. In a controlled lab study, 22 participants improved the design of two different applications. Using a repeated measurement setup, the study examined the effect of providing CoExist on programming performance. The result of analyzing 88 hours of programming suggests that built-in recovery support as provided with CoExist positively has a positive effect on programming performance in explorative programming tasks.Diese Arbeit präsentiert Konzepte und die zugehörige Werkzeugunterstützung um einen komplementären Umgang mit Wiederherstellungsbedürfnissen zu ermöglichen. Programmierer haben Bedarf zur Wiederherstellung eines früheren Entwicklungszustandes oder Teils davon, wenn ihre Änderungen ungewünschte Implikationen aufzeigen. Wenn dieser Bedarf plötzlich und unerwartet auftritt, dann ist die notwendige Wiederherstellungsarbeit häufig mühsam und aufwendig. Zur Vermeidung mühsamer Arbeit empfiehlt die Literatur die Vermeidung von unerwarteten Wiederherstellungsbedürfnissen durch einen strukturierten und disziplinierten Programmieransatz, welcher die Verwendung verschiedener bewährter Praktiken vorsieht. Diese Praktiken sind zum Beispiel: nur an einer Sache gleichzeitig zu arbeiten, immer nur kleine Schritte auszuführen, aber auch der sachgemäße Einsatz von Versionskontroll- und Testwerkzeugen. Jedoch ist der Versuch des Abwendens unerwarteter Wiederherstellungsbedürfnisse sowohl zeitintensiv als auch fehleranfällig. Einerseits erfordert es unverhältnismäßig hohen Aufwand, das Risiko des Eintretens unerwarteter Situationen auf ein Minimum zu reduzieren. Andererseits ist eine zeitsparende selektive Ausführung der empfohlenen Praktiken kaum hinreichend, um Wiederherstellungssituationen zu vermeiden. Zudem bringt die ständige Notwendigkeit an Voraussicht und Selbstkontrolle Nachteile mit sich. Dies ist ermüdend und erschwert das kreative Problemlösen. Diese Arbeit schlägt vor, Wiederherstellungsaufgaben zu vereinfachen und beschleunigen, und stellt entsprechende Werkzeugunterstützung namens CoExist vor. Solche zielgerichtete Werkzeugunterstützung macht aus unvorhergesehenen mühsamen Wiederherstellungssituationen eine konstruktive Erfahrung. Damit ist Wiederherstellung auch dann leicht und schnell durchzuführen, wenn explizit gespeicherte Zwischenstände fehlen oder die Tests für einige Zeit ignoriert wurden. Wenn Fehler und unerwartete Ein- sichten nicht länger mit mühsamen Schadensersatz verbunden sind, fühlen sich Programmierer eher dazu ermutig, Quelltext zu ändern, um dabei darüber zu reflektieren, und nehmen nicht erst dann Änderungen vor, wenn sie diese gedanklich strukturiert und evaluiert haben. Diese Arbeit berichtet weiterhin von einer Implementierung der vorgeschlagenen Werkzeugunterstützung in der Squeak/Smalltalk Entwicklungsumgebung. Regelmäßige Tests von Laufzeitverhalten und Benutzbarkeit begleiteten die Entwicklung. Zudem prüft die Arbeit, ob sich die Verwendung der vorgeschlagenen Werkzeuge auf die Leistung der Programmierer auswirkt. In einem kontrollierten Experiment, verbesserten 22 Teilnehmer den Aufbau von zwei verschiedenen Anwendungen. Unter der Verwendung einer Versuchsanordnung mit wiederholter Messung, ermittelte die Studie die Auswirkung von CoExist auf die Programmierleistung. Das Ergebnis der Analyse von 88 Programmierstunden deutet darauf hin, dass sich eingebaute Werkzeugunterstützung für Wiederherstellung, wie sie mit CoExist bereitgestellt wird, positiv bei der Bearbeitung von unstrukturierten ergebnisoffenen Programmieraufgaben auswirkt.

Ali, S. "Establishment and evaluation of high cell density fermentation processes using a miniature bioreactor in conjunction with ultra-scale cell recovery tools." Thesis, University College London (University of London), 2012. http://discovery.ucl.ac.uk/1383309/.
Full textAbstract:
The use of small scale bioreactors that are mechanically and functionally similar to large scale reactors is highly desirable to accelerate bioprocess development because they enable well defined scale translations. In this study a 25 mL miniaturised stirred tank bioreactor (MSBR) has been characterised in terms of its power input, hydrodynamics and volumetric oxygen transfer coefficient (kLa) to assess its potential to grow high cell density (HCD) cultures using adequate scale-down criteria. Engineering characterisation results showed scale-down, based on matched specific power input (PG/V) and kLa was feasible from the 20 L and 75 L pilot scale stirred tank bioreactors used in this study. In addition, kLa in the MSBR was found to be highest among all three bioreactors suggesting that it was feasible to perform high cell density fermentation in the MSBR. Improvement of mechanical and operational design and optimisation of fed-batch operation resulted in high cell density establishment in the MSBR. Scale-down was performed from 20 L STR to the 25 mL MSBR at matched PG/V, matched kLa and based on dissolved oxygen (DOT>30%) using Fab’ producing E. coli W3110. Comparison of results from the three scaledown strategies shows that matched PG/V was the best strategy and 25 mL MSBR accurately scaled-down the 20 L fermentation performance in terms of growth, Fab’ production and harvest material characteristics at matched PG/V. Scale-down based on dissolved oxygen did not produce reproducible results. Successful scale-down at matched PG/V in the MSBR resulted in maximum cell density of OD600nm~ 114 and total Fab’ concentration of 940 μg/mL compared to OD600nm~118 and 990 μg/mL in 20 L STR. Furthermore, the use of the MSBR in conjunction with primary recovery scale-down tools to assess the harvest material of both reactors showed comparable extracellular viscosity, shear sensitivity and centrifugation performance at both scales when scale-down was performed at matched PG/V. The conjoint use of the MSBR with ultra scale-down centrifugation mimics can provide a cost-efficient manner in which to design and develop bioprocesses that account for good upstream performance as well as their manufacturability downstream. To assess the feasibility of the MSBR to be used for bioprocess development purpose an in-house variant strain of E. coli W3110 co-expressing Fab’ and Staphylococcus aureus nuclease was characterised in 25ml, 20 L and 75 L bioreactor for growth and productivity. Growth and productivity profiles in the pilot scale reactors were successfully scaled-down by 25 mL MSBR when Fab’ fermentation was performed at matched PG/V. Results highlighted in this thesis for successful scale-down high cell density cultivation, use of scale-down recovery tools to predict downstream processibility of the 25 mL harvest, and application of the MSBR for upstream process development of a new strain, suggest that the MSBR can be used for bioprocess development in parallel with pilot scale reactors.

Full textAbstract:
Artificiell intelligens, AI, har länge ersatt människor i fysiskt tunga och monotona uppgifter och har på senare år tagit sig in allt mer i vår vardag i form av allt från robotdammsugare, assistenter som Apples Siri till riktad reklam i sociala medier. I detta masterexamensarbete undersöks huruvida AI skulle kunna implementeras i mer personliga delar av livet, så som i ensorgebearbetningsprocess och hur ett sådant verktyg skulle se ut. Detta görs med en användarcentrerad designmetodik. Användarcentrerad design sätter människan i centrum för den iterativa utvecklings-, design- och beslutsprocessen. Huvudanvändaren i detta projekt är den som genomgår en sorgeprocess, men experter inom ämnet, sjukvården och andra intressenter bör också inkluderas.En bakgrundsstudie grundad på litteratur, forskning och expertutlåtande var basen för projektet. Studiens fokusområden var AI, människa-datorinteraktion, användarcenterad design och sorgeprocessen. En användarstudie om sorgebearbetning genomfördes för att få vidare insikter och bekräfta teorin. Data från semistrukturerade intervjuer och en onlineenkät lade grunden för den analys som resulterade i en rad insikter, en kartläggning av sorgeprocessen samt personas. Dessa användes vidare för idégenerering av designkoncept. Sex stycken koncept på verktyg som skulle underlätta i sorgeprocessen togs fram och deras potential analyserades i tre iterationer tills ett koncept fanns kvar. Analysen gjordes med SWOTanalys samt användartester med triggermaterial. Slutkonceptet, mobilapplikationen Tuki, bygger på insikten att, att prata om sin sorg är det bästa sättet att också bearbeta den, och bäst resultat uppnås vid samtal med en som genomgått en liknande process. Tuki använder språkteknologi för att analysera användardata, för att sedan koppla samman personer med liknande erfarenheter. Konceptet testades och utvecklades tillsammans med användare i workshops med pappersprototyper för att få en så bra användarupplevelse som möjligt. Från dessa workshops skapades en prototyp, service blueprints och en storyboard som beskriver användarens resa. Genom att använda sig av språkteknologi för att förbättra sorgebearbetningsprocessen möter slutkonceptet målen för examensabetet.Artificially intelligent technologies have replaced humans in physically heavy and monotoneduties, and have more recently slid into our daily lives, from robot vacuum cleaners, to personal assistants like Apples Siri, to targeted advertisements in social media. This master thesis researches how AI can be incorporated in personal aspects of life, such as in a grieving process, and aims to develop a relevant tool, employing a user centered design (UCD) methodology. User-centered design puts the user in the center of the research, design and decision process. In this report, ‘user’ refers to griever. However, other stakeholders are also considered in the designprocess. A theoretical pre-study was carried out through literature, research, and expert opinions on the topics relevant to the thesis. The focus areas were AI, Human-Computer Interaction, User-Centered design and grief and the grieving process. A user study regarding grief and the grieving process was conducted to get further insights and confirm the theory. Semi-structured interviews and an online survey were employed, which were analyzed and translated into the insights that served as the foundation for ideation. Ideation resulted in six concepts which were analyzed using SWOT matrices and user tests with trigger materials. The analyses were used to eliminate five concepts. The user studies and research showed that talking about personal grief is the most successful way to process the grief, and best results were gained if the communication was with someone who had gone through something similar. This insight served as the root for the idea to create Tuki. The final concept is a mobile application Tuki (meaning ‘support’ in Finnish) which uses Natural Language Processing (NLP) to analyze the users’ input data regarding their situation, and then matches them to another user with similar experiences.The concept was tested and developed with users in workshops using paper wireframes to get as good a user experience as possible. From these workshops a prototype, service blueprints and astory board were created to envision and describe the user journey with Tuki. Tuki fulfills the goals of the thesis by using AI technology, specifically natural language processing, to ease an identified pain point in the grieving process: the limited possibilities to get in contact with others who had gone through a similar grieving process.

Full textAbstract:
Le métier de dirigeant est riche et complexe et un changement de « numéro un » mal appréhendé peut avoir un impact sur la performance socio-économique, la stratégie, la politique ou encore l’organisation de l’entreprise. Faciliter l’arrivée du nouveau dirigeant est donc un enjeu important pour la survie-développement de l’organisation, d’autant que sa socialisation organisationnelle reste peu étudiée. La première partie explicite les fondements conceptuels et méthodologiques de la recherche, et présente les terrains d’expérimentations de nos hypothèses et de nos outils. L’exploitation d’entretiens réalisés avec des dirigeants permet de définir le métier de dirigeant et de mettre en exergue les rôles et les compétences spécifiques du dirigeant salarié. La relation entre le dirigeant et sa Gouvernance est également étudiée. Son besoin particulier de socialisation organisationnelle est alors démontré, notamment par rapport à un repreneur d’entreprise et à un salarié « classique ». Dans la seconde partie, la théorie de la socialisation organisationnelle est adaptée au métier exigeant et unique de dirigeant, via le concept de Socialisation Organisationnelle du Dirigeant (SOD). Ce modèle répond aux besoins spécifiques de socialisation du dirigeant, notamment lors de l’intégration, étape charnière de la socialisation organisationnelle. Elle est constituée de quatre types de reprises : une reprise politico-stratégique, une reprise organisationnelle, une reprise managériale et une reprise du rôle de dirigeant. La qualité de ces reprises aboutit à la qualité de l’intégration du dirigeant, requalifiée d’intégration stratégique à cause de ses enjeux. Une grille d’analyse est proposée afin de permettre au nouveau dirigeant de mieux appréhender l’organisation qu’il va diriger, mais également ses propres besoins de socialisation organisationnelle au travers des variables et facteurs qui la composentThe job of CEO is rich and complex and the "number one" change, poorly understood, may have an impact on the socio-economic performance, strategy, policy and the organization of the company. Facilitate the arrival of new manager is an important issue for the survival and development of the organization, as well as its organizational socialization remains little studied.The first part explains the conceptual and methodological research, and presents lots of experiments of our assumptions and our tools. We use interviews with executives to define the business leadership and highlight the specifics CEO’s roles and skills. The specific relationship between the leader and its Governance is also studied. Its specific needs of organizational socialization are then demonstrated, particularly in relation to a buyer company and a "classic" employee.In the second part, the concept of organizational socialization is suitable for demanding and unique leader, through the concept of CEO’s Organizational Socialization. This model meets the needs of leader’s socialization, especially during integration, organizational socialization’s milestone. It consists of three types of recoveries: politico-strategic, organizational and managerial. The quality of these recoveries led to the quality of leader’s integration, reclassified strategic integration because of its strategic challenges. An analytical framework is proposed to allow both the new leader to better understand the organization that will lead, but also its own needs through organizational socialization variables and factors that compose it

A tecnologia trouxe à Ciência da Informação uma nova partícula em seu objeto de estudo - a informação na Web; trouxe, também, uma aproximação muito grande entre as Cências da Informação e da Computação. A Internet vem crescendo rapidamente, incrementando a explosão de informações, de forma a termos uma grande quantidade de informação disponível na Web. Desse modo, torna-se necessário investigar tecnologias para descrição e recuperação de informações que possibilitem a organização da informação digital no âmbito da World Wide Web. Valendo-se de pesquisa documental em fontes das áreas de Ciência da Computação e Ciência da Informação e da própria rede Internet foram analisadas as principais linguagens e os recursos para publicação de informações na Web, as formas de descrição e recuperação de informação, as propostas de novos padrões e de estrutura de dados e abordadas as novas ferramentas que vêm sendo discutidas e implementadas, objetivando a organização da informação digital. Verificou-se o delineamento de uma Web Semântica, que se trata de uma extensão da Web atual e que propõe uma nova arquitetura, de maneira que possamos dar significado a toda informação encontrada neste novo conceito de Internet. Tais aspectos permitem concluir que a criação da Web Semântica é uma questão de tempo e que, em breve, essa nova extensão da Web passará a ser um pedaço consistente e qualificado de informações dentro da Internet, possibilitando a várias comunidades a construção de conhecimento a partir de dados confiáveis encontrados na rede.

Full textAbstract:
The LHCb online system relies on a large and heterogeneous IT infrastructure made from thousands of servers on which many different applications are running. They run a great variety of tasks : critical ones such as data taking and secondary ones like web servers. The administration of such a system and making sure it is working properly represents a very important workload for the small expert-operator team. Research has been performed to try to automatize (some) system administration tasks, starting in 2001 when IBM defined the so-called "self objectives" supposed to lead to "autonomic computing". In this context, we present a framework that makes use of artificial intelligence and machine learning to monitor and diagnose at a low level and in a non intrusive way Linux-based systems and their interaction with software. Moreover, the shared experience approach we use, coupled with an "object oriented paradigm" architecture increases a lot our learning speed, and highlight relations between problems.

Resumo: A tecnologia trouxe à Ciência da Informação uma nova partícula em seu objeto de estudo - a informação na Web; trouxe, também, uma aproximação muito grande entre as Cências da Informação e da Computação. A Internet vem crescendo rapidamente, incrementando a explosão de informações, de forma a termos uma grande quantidade de informação disponível na Web. Desse modo, torna-se necessário investigar tecnologias para descrição e recuperação de informações que possibilitem a organização da informação digital no âmbito da World Wide Web. Valendo-se de pesquisa documental em fontes das áreas de Ciência da Computação e Ciência da Informação e da própria rede Internet foram analisadas as principais linguagens e os recursos para publicação de informações na Web, as formas de descrição e recuperação de informação, as propostas de novos padrões e de estrutura de dados e abordadas as novas ferramentas que vêm sendo discutidas e implementadas, objetivando a organização da informação digital. Verificou-se o delineamento de uma Web Semântica, que se trata de uma extensão da Web atual e que propõe uma nova arquitetura, de maneira que possamos dar significado a toda informação encontrada neste novo conceito de Internet. Tais aspectos permitem concluir que a criação da Web Semântica é uma questão de tempo e que, em breve, essa nova extensão da Web passará a ser um pedaço consistente e qualificado de informações dentro da Internet, possibilitando a várias comunidades a construção de conhecimento a partir de dados confiáveis encontrados na rede.

Full textAbstract:
Unauthorized access to computers and theft of proprietary information are two problems leading to large economical losses for organizations around the world. Thousands of laptops often containing vital information are lost at airports every day. Organizations and people in general often believe that the sensitive information is inaccessible because of the login mechanism. Even though we demand that our systems should prevent unauthorized access, we also expect that the access to the operating system can be restored when a password is lost. We require that authorized persons can regain the access to the computer, while unauthorized persons are prevented access. A good solution to reset or recover the Administrator password should exist on all operating systems. This thesis begins with addressing weaknesses in 8 different operating systems. It presents a comprehensive step-by-step guide for already existing procedures and tools that can be used to reset or recover the Administrator password. In total 6 procedures and 10 tools are presented. Because some procedures required a lot of interaction from the user, we decided to automate these and include them in our self made tool named Yet Another Local Password (tool) (YALP). We were able to reset the passwords on all of the 8 operating systems. On some of the operating systems only a few passwords were recovered, and based on that, a more comprehensive password recovery study was desirable. It should be noted that even though Microsoft has introduced a more secure password handling mechanism on newer Windows operating system, many persons and corporations still use the outdated Windows XP operating system. This is partly because Windows Vista has been criticized for its weak performance. An empirical password study was carried out to see what percentage of 30 carefully chosen passwords could be revealed. Some disturbing results were obtained. During a period of 8 hours, 100% of the passwords created on a Windows XP system were revealed. The results from this study show that the use of password as an authentication mechanism for operating systems will not offer sufficient protection in the future, and that other mechanisms have to be considered. Based on results obtained from this thesis, a paper named All in a day's work: Password cracking for the rest of us was submitted to The 14th Nordic Conference on Secure IT Systems, NordSec 2009, in Oslo, Norway. In addition, a poster named Generation of Rainbow Tables was presented at The 8th Annual Meeting on High Performance Computing and Infrastructure, NOTUR2009, in Trondheim, Norway. The poster and the paper are included in Appendix F and Appendix G, respectively.

Williams, Christian. "The development, reliability and validity testing of an observation tool designed to measure recovery orientation in inpatient recovery and rehabilitation services." Thesis, Cardiff University, 2016. http://orca.cf.ac.uk/98942/.
Full textAbstract:
AIM: Recovery orientation is important to inpatient mental health services. However, it has proved difficult to measure and hence to implement. Using an observational method, this project aimed to design a tool for assessing the recovery orientation of a service, and to test its reliability and validity. METHOD: From the recovery literature over-arching themes in the recovery process were identified. From these, descriptions of types of interactions between patients and staff members, termed ‘codes’, were developed. Using a Delphi method, experts working in inpatient Rehabilitation services agreed which codes should be included in the tool. Staff teams in seven wards completed a standardised measure of Recovery (Recovery-Self Assessment [RSA]). The wards with the highest and lowest mean scores were used to pilot the new tool. Time sampling was used to capture interactions between staff and patients on both wards. These were coded using the new tool. Interactions coded as supporting recovery were rated positive; those coded as hindering recovery were rated negative. It was hypothesised that more positively coded interactions would be observed on the ward with the highest RSA score. Reliability was assessed by comparing percentage agreement between two researchers independently coding 20% of the observed interactions. Validity was assessed by comparing the number of positive and negative interactions on the two wards. FINDINGS: 23 of the 30 codes developed were included in the final tool. The reliability of the tool was good with 93.8% agreement on positive/negative ratings (Kappa 0.827). However, the validity was poor, with Chi-square showing no significant difference between wards in the number of positive and negative interactions. CONCLUSION: The evidence base for the tool is sound. Its reliability is encouraging. The poor validity may be because the two test wards did not differ greatly on the RSA. Further development of both the codes used to construct the tool and the method in which it is used could provide a clinically useful tool for Services.

Bishop, Katherine. "Using cultural heritage as a tool in post-war recovery : assessing the impact of heritage on recovery in post-war Dubrovnik, Croatia." Thesis, University of York, 2014. http://etheses.whiterose.ac.uk/22242/.
Full textAbstract:
Cultural heritage is a significant aspect of both conflict and the recovery from conflict, but its role in shaping and influencing the post-conflict landscape has not been fully explored conceptually, nor has its role been fully implemented into recovery processes by practitioners. This thesis explores the disjuncture that exists between heritage theorists’ conceptualisation of cultural heritage as a cultural process, and practitioners’ tendency to privilege material reconstruction. By bridging cultural heritage and post-conflict literatures, the thesis presents the foundations for a holistic approach to cultural heritage in post-conflict settings. An Integrated Heritage Assessment Framework (IHAF) is developed to operationalise this holistic conceptualisation. This thesis makes three key contributions to the fields of cultural heritage studies and conflict studies. The first is a substantial contribution to the literature by reconceptualising the use of heritage in post-conflict recovery to argue for a shift away from reductive uses of heritage as cultural property towards more expansive notions of heritage as a process that can actively influence the course of recovery. Secondly, and building upon this conceptual foundation, the thesis has created and tested a methodological framework, the IHAF, capable of balancing recovery practitioners’ and policy-makers’ priorities with a nuanced conceptualisation of heritage. The purpose of this framework is to identify what impact heritage has on recovery, in order to reposition heritage as an active component of recovery processes, and remove it from being perceived as passive recipient of damage and restoration. The third aspect of the thesis applies the IHAF to the case study of Dubrovnik, Croatia, demonstrating the impact of heritage in three key areas of the city’s recovery. This assessment of Dubrovnik’s physical, economic and socio-political recovery viewed through the active lens of heritage adds an important new perspective on the Old Town’s long term narrative of recovery and reconciliation. The thesis demonstrates the importance of the Integrated Heritage Assessment Framework and its potential broader application to different conflicts, and in doing so, puts heritage firmly at the heart of post-conflict recovery.

Full textAbstract:
This thesis reports the research efforts conducted in order to develop the Dynamic Response Recovery Tool. The DRRT was developed as a decision support tool under a holistic approach considering both emergency management research and transportation studies. The proposed system was assessed by a series of case studies in order to identify its efficiency and suitability for roading organisations.
Knowledge developed from two novel research approaches are comprehensively described throughout the thesis. Initially, we report on the observation of three emergency exercises and two real events in New Zealand. This set of activities indicated the complex and dynamic environment in which emergency management takes place as well as organisational settings and management structures implemented to better respond and recover from disasters events. Additionally, a secondary approach was designed to overcome limitations identified in the observation method. In this context, a game-based scenario simulation was developed and conducted with twelve participants. With a focus in resource deployment decisions during emergencies, the game simulated an earthquake scenario in which participants had to allocate physical resources to fix damage created in a road network. Simulations indicated that Naturalistic Decision-making processes were used to respond to the scenario. Thus, resource allocation followed planning priorities defined previously the simulation, which further considered individual experiences and knowledge.
Taking advantage from the findings achieved and knowledge developed by the observations and game simulations, the DRRT was designed using the conceptual background identified in the literature review. The DRRT was conceptualised as a logistics sub-system as part of the broad field of Disaster Management. In particular, the DRRT was geared towards supporting decision-making by providing procedural recommendations and identifying optimum physical deployment strategies. In order to assess the proposed system, an Information Technology application was built according to the DRRT’s specifications.
A series of eleven individual and three group simulations was performed in order to assess the DRRT. Data collected through the application indicated that the DRRT enhanced decision-making during extreme events. In specific, case study participants using the system at greater levels achieved better decision-making accuracy than those disregarding completely or partially the system. Case studies also indicated that emergency management knowledge was represented by the application and its logistics model provided participants with vital information to optimise resource allocation.

O uso de robôs de busca para coletar informações para um determinado contexto sempre foi um problema desafiante e tem crescido substancialmente nos últimos anos. Por exemplo, robôs de busca podem ser utilizados para capturar dados de redes sociais profissionais. Em particular, tais redes permitem estudar as trajetórias profissionais dos egressos de uma universidade, e responder diversas perguntas, como por exemplo: Quanto tempo um ex-aluno da PUC-Rio leva para chegar a um cargo de relevância? No entanto, um problema de natureza comum a este cenário é a impossibilidade de coletar informações devido a sistemas de autenticação, impedindo um robô de busca de acessar determinadas páginas e conteúdos. Esta dissertação aborda uma solução para capturar dados, que contorna o problema de autenticação e automatiza o processo de coleta de dados. A solução proposta coleta dados de perfis de usuários de uma rede social profissional para armazenamento em banco de dados e posterior análise. A dissertação contempla ainda a possibilidade de adicionar diversas outras fontes de dados dando ênfase a uma estrutura de armazém de dados.
The use of search bots to collect information for a given context has grown substantially in recent years. For example, search bots may be used to capture data from professional social networks. In particular, such social networks facilitate studying the professional trajectory of the alumni of a given university, and answer several questions such as: How long does a former student of PUC-Rio take to arrive at a management position? However, a common problem in this scenario is the inability to collect information due to authentication systems, preventing a search robot from accessing certain pages and content. This dissertation addresses a solution to capture data, which circumvents the authentication problem and automates the data collection process. The proposed solution collects data from user profiles for later database storage and analysis. The dissertation also contemplates the possibility of adding several other sources of data giving emphasis to a data warehouse structure.

Full textAbstract:
Thesis (MTech (Medical Technology))--Cape Technikon, Cape Town, 2002Erythropoietic response is the first indication of bone marrow recovery following bone marrow or peripheral blood stem cell transplantation. Manual reticulocyte counting has not only proven to be outdated but an extremely crude method of analysis, particularly if accurate and reliable means of assessing erythroid response is required to assess bone marrow recovery. Automated methods allow for the quantification of maturation within each reticulocyte, by measuring the amount of RNA present. The method of choice for our reticulocyte analysis was the Reticulocyte Maturation Index (RMI). The RMI was obtained by dividing the number of immature reticulocytes counted by the total number of reticulocytes counted producing a reportable value of International Units (IU). A normal Reticulocyte Maturation Index is 0.20 to 0.50 IU. The aim of the study was multifold. We wanted to prove that the Reticulocyte Maturation Index (RMI) is indeed the fastest means to assess bone marrow recovery in various types of transplants, including Bone Marrow Transplant (BMT) and Peripheral Blood Stem Cell Transplant (PBSCT). We also wanted to draw comparisons between allogeneic and autologous transplants, as well as further assessing different disease types. This was done by measuring the Reticulocyte Maturation Index (RMI), Absolute Neutrophil Count (ANe) and the Platelet Count (PLT) within the various groups. We further wanted to assess the effect of preconditioning treatment, Mononuclear Counts (MNC) and Colony Forming Unit - Granulocyte and Monocyte Counts (CFU-GM) on the early RMI response. These comparisons resulted in a need to establish a working range to determine patients response therein, and final outcome of the transplants. Finally we wanted to establish whether the "day 14" marrow biopsy is necessary, particularly if the three peripheral blood parameters, RMI, ANC and PLT were used as routine procedure following transplantation. The Reticulocyte Maturation Index (RMI) was measured on the Coulter EPICS ProfIle II flow cytometer; the ANC and PLT were measured on the Technicon H2 Haematology System. All other results such as the Mononuclear Counts (MNC), Colony Forming Unit - Granulocyte and Monocyte counts (CFU-GM), "day 14" and "day 28" bone marrow biopsies were retrieved from laboratory records. Forty nine transplant patients were evaluated for RMI over a period of six months, at the Department of Haematology, Groote Schuur Hospital, Cape Town. Four patients failed to engraft; and were not used in the calculations; but were evaluated as an aspect of the study in the final analysis. Forty five patients were analysed to establish the values used in the study, these patients were divided into eleven groups.

Full textAbstract:
I analyzed lake fertilization (with nitrogen and phosphorus) as a tool to assist in the recovery of the Snake River sockeye salmon (Oncorhynchus ~) in the oligotrophic Sawtooth Valley Lakes in southcentral Idaho. These analyses involved monitoring, manipulating, and modelling several aspects of the lakes' primary producer, nutrient, and light parameters.
In Pettit Lake, I evaluated the effects of metalimnetic and epilimnetic fertilization in 330-m 3 mesocosms. The metalimnetic treatment was equal to or more effective than the epilimnetic treatment in increasing chlorophyll a, phytoplankton biovolume, and primary productivity, yet caused smaller changes in periphyton growth and water clarity. Thus, metalirnnetic fertilization may provide a tool for increasing lake productivity while minimally impacting water clarity.
The Sawtooth Valley Lakes had deep chlorophyll maxima (DCM) with mean chlorophyll a peaks 240-1000% of mean epilimnetic concentrations. The DCM existed at low light levels and accounted for 36- 72% of the lakes' primary production. Epilimnetic fertilization of330-m 3 mesocosms in Redfish Lake increased levels of primary productivity and chlorophyll a, but decreased Secchi depths and light available in the meta- and hypolimnion. I modelled the effects of increased chlorophyll (resulting from epilimnetic fertilization) and decreased light penetration on vertical primary productivity profiles. The simulations showed a large increase in epilimnetic primary productivity due to fertilization, and only a slight decrease in production in the deeper strata due to self-shading.
I also modelled the dependence of Red fish Lake's production on nutrients from the watershed, from lake fertilization, and from marine-derived nutrients from salmon. The model utilized our water budget and nutrient loading measurements. The model and empirical evidence indicated that even before hydropower dams were present in the migration corridor, marine-derived nutrients were not of major importance to lake production, contributing only ~3% of the lake's annual phosphorus load. This contribution was partially offset by the lake's quick flushing rate (3 yr) and phosphorus export by smolts. The model predicted annual adult salmon returns to be 3,800 under pre-dam conditions, 370 under modern conditions, 750 when doubling watershed nutrient loading (simulating lake fertilization), and 780 when doubling migration survival.

Full textAbstract:
Muscle wasting is a common consequence of critical illness, leading to long-term physical morbidity. Early rehabilitation in the Critical Care Unit (CCU) is now the norm. Guidelines suggest that this rehabilitation should be goal-directed and based on comprehensive assessment of physical function, however there was no tool to assess physical function objectively. The aim was to evaluate the clinimetric properties of the Chelsea Critical Care Physical Assessment tool (CPAx); a tool designed to measure function in critical illness objectively; to explore the patient experience of the CPAx in early rehabilitation, and; to use the CPAx to evaluate common recovery trajectories. This was a convergent mixed methods study. Preparatory work included integration of the CPAx into clinical practice, allowing recording of daily CPAx. Observational cohort studies were completed to determine the validity, responsiveness, and floor/ceiling effect of the CPAx. The database was also used to explore daily functional recovery and to establish the minimal detectable change (MDC) of the CPAx. An eLearning module to teach clinicians how to use the CPAx was developed and distributed with evaluative questionnaires to determine the CPAx’s content validity. Case studies were embedded in the module for inter-rater reliability testing. Grounded-theory methodology with semi-structured interviews was used to explore the patient experience of the CPAx tool in early rehabilitation. The results showed that the CPAx is valid, reliable, responsive, and widely used; however, it is likely to have a ceiling effect after hospital discharge. The CPAx may have a role in goal setting for long-stay patients and help to fill in loss of life narrative after critical illness; however the CPAx is difficult to comprehend in the early days of CCU, which are overshadowed by delirium, sleep deprivation and fatigue. Function and CCU length of stay are closely associated, suggesting that function may influence length of stay.

Full textAbstract:
In the study of government accountability, there have long been arguments about which model is superior. These arguments, which are largely made by those in the performance and political accountability camps, state that their particular model is the best, and indeed only legitimate approach to ensuring accountable government. At the same time, there is growing research in policy tools but little in how accountability models and policy tools are linked in policy design.
This study makes use of the context provided by the critical cases of the Troubled Asset Relief Program (TARP) and the American Recovery and Reinvestment Act (ARRA). With such large sums of money in play at a time of serious economic downturn and mounting federal deficits, government clearly has a responsibility to ensure accountability so that the public can be assured not only that its funds are being spent properly but also more generally, that accountability as well as policy tool choice is in the minds of officials as they formulate, adopt and implement public policy.
The intent of this study is to present an argument in two main areas using the critical case studies of TARP and ARRA. First, that no one accountability model fully explains most policy tool choices in TARP or ARRA and that the use of multiple models is superior. Second, that we can link policy tool choices and accountability models in policy design. The standards used to establish what models explain what tool choices are in the models themselves. Each policy is explored individually in a chapter, and the lessons and results of this study are then presented in the final chapter.
The data presented in this study indicate that a single-model approach may explain a few, but not most and certainly not all, policy tool choices in TARP and ARRA. Indeed, a multiple model approach proves superior to a single-model approach in all but a few instances. As for the connections between policy tools and accountability models, the data presented in this study show that they were strongly impacted by the policy formulation process itself, specifically the way in which the policy problem was framed and the speed with which it was undertaken.

Full textAbstract:
In the acute stages following ABI, when people are functionally dependent, a specific scale for physiotherapists to monitor incremental changes in neuro-motor function is needed. This thesis represents the development of the acute brain injury physiotherapy assessment (ABIPA), an outcome measure to fill this gap. The first step in the development of the ABIPA was to identify items known to reflect acute neuro-motor impairments for inclusion in the measure and develop scoring criteria along with guidelines for the identified items (Study 1). The final items of the ABIPA were: upper limb and lower limb movement; overall muscle tone in each limb; head and trunk alignment in supine; head and trunk alignment in sitting; head and trunk control in sitting; and overall presentation. Once items were selected and scoring criteria established, the new outcome measure underwent psychometric testing. In Study 1 responsiveness and concurrent validity of the ABIPA were examined together with participants assessed at day 1, 3, 7 and at discharge through their acute hospital admission to capture clinical changes. Concurrent validity of the ABIPA was examined against other commonly used measures; specifically, the Glasgow Coma Scale (GCS), Clinical Outcomes Variable Scale (COVS) and Motor Assessment Scale (MAS). The ABIPA was found to be responsive to change demonstrating greater sensitivity to change (SRM = 0.83) when compared to other assessment measures (SRMs ≤ 0.77) during the early weeks following ABI. Additionally, the ABIPA demonstrated good concurrent validity with commonly used measures to assess acute brain injury, including the GCS (rho = 0.76, p ≤ 0.001, COVS (rho = 0.82, p ≤ 0.001) and MAS (rho = 0.66, p ≤ 0.001). Study 2 of this thesis investigated inter- and intra-tester reliability of physiotherapists using the ABIPA. An observational study using video-recorded ABIPA assessments of seven people with moderate or severe ABI was undertaken with two cohorts of physiotherapists; trained and untrained. Trained physiotherapists attended two one-hour training sessions; an initial instructional session and then a practice session. The untrained physiotherapists were provided with the ABIPA guidelines. Participating physiotherapists scored the video recorded package of ABIPA assessments with intra-tester reliability examined by repeat screenings of the video recorded assessments a minimum of two weeks after the initial session. A high level of inter-tester reliability (α ≥ 0.9) was demonstrated for both trained and untrained physiotherapists. Trained physiotherapists showed good to excellent internal consistency for total ABIPA score and for all individual items except for alignment of the trunk in supine (α = 0.4). Similarly, untrained physiotherapists showed good to excellent internal consistency on the total ABIPA score and all individual items except for alignment of the trunk in supine (α = 0.09) and alignment of the head in supine (α = 0.60). For intra-tester reliability, substantial or perfect agreement was achieved for eight items (Weighted kappa Kw ≥ 0.6), with moderate agreement reached for a further four items (Kw = 0.4 - 0.6), leaving three items (representing 20% of the scale) achieving fair agreement. Items with the lowest agreement were alignment of the head in supine (Kw = 0.289); alignment of the trunk in supine (Kw = 0.387) and tone left upper limb (Kw = 0.366). This was similar for both the trained and untrained physiotherapists. Study 3 of the thesis investigated the underlying factor structure of the ABIPA using an exploratory factor analysis with principal axis factor extraction and varimax rotation. A four-factor solution with a simple structure (factor loadings ≥.30) that explained 69.6% of total variance was suggested. Factor one (alignment and posture) accounted for 36.6% of the variance while factor two (tone) explained 15.8%, factor three (left side movement) explained 9.6% and factor four (right side movement) accounted for 7.5%. Two items were identified with the lowest loading with the four-factor solution, alignment of the head in supine loading to factor three at 0.358 and alignment of the trunk in supine loading to factor two at 0.405. The final study of this thesis examined the association of the ABIPA with long term recovery following ABI by evaluating ABIPA scores at acute hospital admission and ABIPA scores at admission to rehabilitation against: length of stay in the acute hospital setting, length of stay in rehabilitation, discharge destination and secondary measures including the GCS, Mental Status Questionnaire, COVS, Coma Recovery Scale-Revised (CRS-R), Functional Independence Measure (FIM), Disability Rating Scale (DRS) and Carer Strain Index (CSI). ABIPA at acute hospital admission and rehabilitation were inversely related to acute, rehabilitation and total hospital length of stay (rho ≥ -.508; p ≤ 0.044). ABIPA at acute hospital admission demonstrated moderate to good correlations with ABIPA, FIM (motor) and COVS (rho ≥ 0.563, p ≤ 0.023) at long term follow up. ABIPA scores at rehabilitation admission demonstrated moderate to good correlations with GCS and MSQ (rho ≥ 0.564, p ≤ 0.023) and excellent correlations with ABIPA, FIM (motor) and COVS (rho ≥ 0.799, p ≤ 0.001). Overall the ABIPA showed moderate to good relationships with length of stay and long-term neuro-motor recovery from severe ABI. This thesis demonstrates that a new outcome measure with strong psychometric properties has been developed for measurement of acute neuro-motor impairments following severe ABI. Further investigation is required to continue the development paradigm by removing outlying items, establishing a minimal clinically important difference and expanding participant numbers.

Abstract This study identified earnings management to meet each of three thresholds: avoiding earnings losses, sustaining last year’s earnings performance, and exceeding mandatory management forecast errors. We explored the behavior of earnings management in banking and examined whether the accrual items were used to be the important managed tools. Under this hypothesis established, we recovered the nature of earnings by accrual items. Furthermore, we also explored what the audit quality impacted on the behavior of earnings management. Our empirical result was that the density of the distribution of earnings discontinued between the treatment group (the banks had small positive earnings) and the controlled group (the banks had small negative earnings). Therefore, the banking managed earnings to avoid earnings losses. In characteristics of accrual items, discretionary accruals or bad debts were the important tools. By reducing the changes of discretionary accruals or bad debts to manage earnings, the distribution of recovery earnings continued between the treatment group and the controlled group. That is the distribution of recovery earnings became smoother. Second, we found that the density of the distribution of mandatory management forecast errors discontinued at the treatment group (the banks’ forecast errors had below absolute value of 20%) and the controlled group (the banks’ forecast errors had under absolute value of 20%). In other words, the banking managed earnings not to exceed the threshold of mandatory management forecast errors. In characteristics of accrual items, discretionary accruals or security exchanging gains (losses) were the important tools to manage earnings. By reducing the changes of discretionary accruals or security exchanging gains (losses), the distribution of recovery mandatory management forecast errors continued between the treatment group and the controlled group. Therefore, the distribution of recovery mandatory management forecast errors became smoother. However, the earnings changes samples didn’t have the above-mentioned phenomena. Besides, audit quality didn’t affect the behavior of earnings management in the banking of Taiwan, either.

Dissertação de mestrado integrado em Engenharia e Gestão IndustrialThe main goal of this Project was to analyze with resource to Quality Tools the Current Warranty Process and the Warranty Claims since 2012 until the First Quarter of 2015, in order to recover from Supplier the Quality Costs regarding defective materials. This dissertation was developed in the Automotive Industry in Delphi Automotive Systems Portugal S.A. Currently, the Quality Costs regarding each Warranty Claim are unknown by Delphi, setting a fixed value of 1000 € for each Warranty issue, that is not valid at Supplier’s eyes, considering it does not reflect the real costs of each claim and it is much higher than the price that Delphi paid for each component. Although, Delphi has a Zero Defects Policy and did not pay for No Quality regarding defective components, is being charged by Customer. Delphi Braga wants to be the first company in Delphi group to recover Quality Costs from every Supplier, in order to raise awareness and to ensure that every Supplier is committed to Delphi Policy and to minimize the current Quality Costs. According to the Literature, one of the principles of Quality Continuous Improvement is based on the assumption that every decision, in special those which are taken by Quality Team, should rely on the use of Quality Tools, for the purpose to discover the critical root causes to be solved and to implement corrective actions, ensuring the Quality Standards. The higher is the short-term investment in Costs of Good Quality as Prevention and Appraisal Costs, the less are the long-term costs of Poor Quality throughout the Supply Chain as Internal and External Failure Costs, ensuring a win-win strategy for all stakeholders and nurturing business partnership towards Delphi requirements of being known among Customers as their best Supplier, surpassing their highest expectations. A rigorous analysis was undertaken to 7696 Warranty Claims from 2012 until the First Quarter of 2015, concluding that there are 153 complaints confirmed by supplier analysis as defective material corresponding to a total of 80.724.31€. Given that, the Quality Costs were associated to each Warranty Claim, creating a cost-oriented Database with all the Customer Debit Costs per device and when added to the Analysis Costs, the amount that Delphi has to recover from Supplier was calculated.
O objetivo principal deste projeto é a análise, com recurso às Ferramenta da Qualidade, do Atual Processo de Garantia e das Reclamações ao abrigo da Garantia desde 2012 até ao 1º Quadrimestre de 2015, para recuperar Custos de Qualidade junto do fornecedor relativos a defeitos de material. Esta dissertação foi desenvolvida na Indústria Automóvel na Delphi Automotive Systems Portugal S.A. Atualmente, os Custos da Qualidade relativos a cada Reclamação de Garantia não são conhecidos pela Delphi, tendo-se fixado um valor de 1000 € para cada defeito de Garantia, o que não é válido do ponto de vista do fornecedor, uma vez que não reflete os custos reais de cada reclamação e é muito superior ao preço que a Delphi paga por componente fornecido. Embora a Delphi tenha uma Política de Zero Defeitos e não paga por componentes fornecidos defeituosos, tem de pagar ao Cliente. A Delphi Braga quer ser a primeira empresa no grupo Delphi a recuperar Custos de Qualidade de todos os Fornecedores, de forma a consciencializar e a assegurar que cada Fornecedor está comprometido com a Política da Delphi para minimizar os atuais Custos de Qualidade. De acordo com a Literatura, um dos princípios da Melhoria Contínua da Qualidade é baseado no pressuposto de que todas as decisões, em especial aquelas que são tomadas pela Equipa de Qualidade, devem depender das Ferramentas da Qualidade com o propósito de descobrir as causas-raiz críticas a serem resolvidas e as medidas corretivas a serem implementadas, garantindo os Padrões de Qualidade. Quanto maior for o investimento a curto-prazo em Custos de Boa Qualidade, menor são os custos a longo-prazo da Má Qualidade ao longo da cadeia de abastecimento, assegurando uma estratégia mutuamente benéfica para todos os intervenientes e alimentando parcerias comerciais, tendo em vista os requisitos da Delphi, de ser conhecida entre os seus clientes como o seu melhor fornecedor, superando as suas maiores expectativas. Foi realizada uma análise a 7696 Reclamações de Garantia desde 2012 até 1ºQuadrimestre de 2015, concluindo que existem 153 reclamações confirmadas pelo Fornecedor, como sendo defeitos de material, correspondendo a um total de 80.724.31€. De forma a materializar este valor, os Custos da Qualidade foram associados a cada Reclamação de Garantia, criando uma base de dados orientada aos custos, onde são apresentados todos os Custos Debitados pelo Cliente por aparelho e quando somados aos Custos de Análise, é obtido o valor que a Delphi deve recuperar.

Full textAbstract:
The studies described here introduce a model for residue preservation on stone
tools. They simulate stone tool manufacture in order to define parameters important
for the study of DNA residues. Microscopic examination of stone tools has identified
microcracks that trap DNA and protein from animal blood cells. Thorough
investigation of different methods to recover residues from stone tools shows that
surface washing leaves DNA and protein, trapped in subsurface microcracks.
However, other extraction techniques are able to release 60-80% of DNA and protein
residues.
Previous research documents the identification of protein from stone tools
sonicated in 5% ammonium hydroxide, but it remains untested whether the same
treatment yields useable DNA. Using this treatment, I identified 13-year-old DNA
residues from experimentally manufactured stone tools. In addition, results clearly
indicate that washing procedures typically used to curate stone tools removed only a
small fraction of the DNA deposited during animal butchery.
Twenty-four pieces of chipped stone recovered from the Bugas-Holding site
were studied to explore the validity of ancient DNA residue identifications. Nine tools
yielded DNA residues. Modern humans did not touch three of these tools, which
suggests that the DNA recovered from them was present prior to excavation. One
tool, which was handled by excavators without gloves, harbored DNA from three
species, and these templates competed during PCR. On at least two tools, handling
after excavation introduced animal DNA unrelated to tool use. Careful testing of
Bugas-Holding chipped stone suggests that stone tools may harbor both ancient and
modern DNA, and that investigators must take great care to exclude modern DNA
from ancient specimens.
Ultimately, I developed and streamlined a method to analyze DNA-containing
residues preserved on stone tools. This led to several technical improvements in
ancient DNA residue analysis. These include a more effective DNA recovery
protocol, methods to measure sensitivity and inhibition of PCR in each sample, and
strategies to surmount competition between templates during amplification, which can
occur in samples that contain DNA from multiple species. These new developments
will help future investigators achieve the full potential of ancient DNA residue
analysis.Graduation date: 2003

Tool life model for printed circuit board (PCB) drilling process will be established to predict the tool life. The tool exchange controller built in an open CNC can automatically remove the worn drill while the life is finished according to the model. The drill breakage detector is connected with the CNC given that the controller in the CNC can remove the broken drill automatically without machining termination. The machining time reduces and machining accuracy can be maintained while the controller works in the CNC. The exchange controller is prescribed by the macro function in the open CNC, which can detect the tool breakage via the sensor mounted on the main axis. The tool management is also prescribed by macro function, which can monitor the tool life during the whole drilling process. A new drill will be found and reset on the main axis by the exchange controller while the management finds the terminated life. The precision can be maintained via the replacement of several new drills. The deviation error and machining time will be verified through the experiments. The error is constrained below a desired specification and the operation time will reduce comparing with the one of manual operation.

The fact that maintenance cost occupies almost two-thirds of the total software cost is reported repeatedly in past research literature. The high cost of software maintenance can be attributed to some common maintenance problems such as outdated software documents and skewed software architecture. This paper proposes a method undertaken by a medical center located in southern Taiwan to recover software architecture and rebuilt documentation of its Hospital Information System (HIS). The architecture and documentation will serve as the foundation of migrating applications from legacy HIS systems to a component-based architecture. Our research starts with defining maintenance-oriented software architecture by conducting literature study and interviewing experienced software analysts. Then, we proceed the architecture extraction phase by analyzing source code and the recovered architectural information are then saved into a repository in a top-down fashion. As we re-construct the architecture, software developers need to provide some additional descriptions to complete the documentation. A software architecture management system is developed to assist software developers in querying and maintaining software system documentation. Finally, we propose a mechanism to inform software maintainers to update program specification simultaneously while maintaining programs. We expect that the recovered architectural information could be used to evaluate change impacts and to estimate maintenance cost in the future.

Full textAbstract:
A significant amount of Viscous Oil (e.g., heavy oil, extra heavy oil, and bitumen) is trapped in Naturally Fractured Carbonate Reservoirs also known as NFCRs. The word VO endowment in NFCRs is estimated at ~ 2 Trillion barrels mostly reported in Canada, the USA, Russia, and the Middle East. To date, contributions to the world daily oil production from this immense energy resource remains negligible mainly due to the lack of appropriate production technologies. Implementation of a VO production technology such as steam injection is expensive (high capital investment), time-consuming, and people-intensive. Hence, before selecting a production technology for detailed economic analysis, use of cursory or broad screening tools or guides is a convenient means of gaining a quick overview of the technical feasibility of the various possible production technologies applied to a particular reservoir. Technical screening tools are only available for the purpose of evaluation of the reservoir performance parameters in oil sands for various thermal VO exploitation technologies such as Steam Assisted Gravity Drainage (SAGD), Cyclic Steam Stimulation (CSS), Horizontal well Cyclic steam Stimulation (HCS), and so on. Nevertheless, such tools are not applicable for VO NFCRs assessment without considerable modifications due to the different nature of these two reservoir types (e.g., presence and effects of fracture network on reservoir behavior, wettability, lithology, fabric, pore structure, and so on) and also different mechanisms of energy and mass transport. Considering the lack of robust and rapid technical reservoir screening tools for the purpose of quick assessment and performance prediction for VO NFCRs under thermal stimulation (e.g., steamflooding), developing such fast and precise tools seems inevitable and desirable.
In this dissertation, an attempt was made to develop new screening tools for the purpose of reservoir performance prediction in VO NFCRs using all the field and laboratory available data on a particular thermal technology (vertical well steamflooding). Considering the complex and heterogeneous nature of the NFCRs, there is great uncertainty associated with the geological nature of the NFCRs such as fracture and porosity distribution in the reservoir which will affect any modeling tasks aiming at modeling of processes involved in thermal VO production from these types of technically difficult and economically unattractive reservoirs. Therefore, several modeling and analyses technqiues were used in order to understand the main parameters controlling the steamflooding process in NFCRs and also cope with the uncertainties associated with the nature of geologic, reservoir and fluid properties data. Thermal geomechanics effects are well-known in VO production from oil sands using thermal technologies such as SAGD and cyclic steam processes. Hence, possible impacts of thermal processes on VO NFCRs performance was studied despite the lack of adequate field data.
This dissertation makes the following contributions to the literature and the oil industry: Two new statistical correlations were developed, introduced, and examined which can be utilized for the purpose of estimation of Cumulative Steam to Oil Ratio (CSOR) and Recovery Factor (RF) as measures of process performance and technical viability during vertical well steamflooding in VO Naturally Fractured Carbonate Reservoirs (NFCRs). The proposed correlations include vital parameters such as in situ fluid and reservoir properties. The data used are taken from experimental studies and also field trials of vertical well steamflooding pilots in viscous oil NFCRs reported in the literature. The error percentage for the proposed correlations is < 10% for the worst case and contains fewer empirical constants compared with existing correlations for oil sands. The interactions between the parameters were also considered. The initial oil saturation and oil viscosity are the most important predictive factors. The proposed correlations successfully predicted steam/oil ratios and recovery factors in two heavy oil NFCRs. These correlations are reported for the first time in the literature for this type of VO reservoirs.
A 3-D mathematical model was developed, presented, and examined in this research work, investigating various parameters and mechanisms affecting VO recovery from NFCRs using vertical well steamflooding. The governing equations are written for the matrix and fractured medium, separately. Uncertainties associated with the shape factor for the communication between the matrix and fracture is eliminated through setting a continuity boundary condition at the interface. Using this boundary condition, the solution method employed differs from the most of the modeling simulations reported in the literature. A Newton-Raphson approach was also used for solving mass and energy balance equations. RF and CSOR were obtained as a function of steam injection rate and temperature and characteristics of the fractured media such as matrix size and permeability. The numerical solution clearly shows that fractures play an important role in better conduction of heat into the matrix part. It was also concluded that the matrix block size and total permeability are the most important parameters affecting the dependent variables involved in steamflooding.
A hybrid Artificial Neural Network model optimized by co-implementation of a Particle Swarm Optimization method (ANN-PSO) was developed, presented, and tested in this research work for the purpose of estimation of the CSOR and RF during vertical well steamflooding in VO NFCRs. The developed PSO-ANN model, conventional ANN models, and statistical correlations were examined using field data. Comparison of the predictions and field data implies superiority of the proposed PSO-ANN model with an absolute average error percentage < 6.5% , a determination coefficient (R2) > 0.98, and Mean Squared Error (MSE) < 0.06, a substantial improvement in comparison with conventional ANN model and empirical correlations for prediction of RF and CSOR. This indicates excellent potential for application of hybrid PSO-ANN models to screen VO NFCRs for steamflooding. This is the first time that the ANN technique has been applied for the purpose of performance prediction of steamflooding in VO NFCRs and also reported in the literature. The predictive PSO-ANN model and statistical correlations have strong potentials to be merged with heavy oil recovery modeling softwares available for thermal methods. This combination is expected to speed up their performance, reduce their uncertainty, and enhance their prediction and modeling capabilities.
An integrated geological-geophysical-geomechanical approach was designed, presented, and applied in the case of a NFCR for the purpose of fracture and in situ stresses characterization in NFCRs. The proposed methodology can be applied for fracture and in situ stresses characterization which is beneficial to various aspects of asset development such as well placement, drilling, production, thermal reservoir modeling incorporating geomechanics effects, technology assessment and so on. A conceptual study was also conducted on geomechanics effects in VO NFCRs during steamflooding which is not yet well understood and still requires further field, laboratory, and theoretical studies. This can be considered as a small step forward in this area identifying positive potential of such knowledge to the design of large scale thermal operations in VO NFCRs.

No início de 2016, a Comissão Europeia impôs, na Zona Euro, o mecanismo do bail-in como procedimento padrão para recuperar e resolver os bancos que foram enfraquecidos pela crise financeira. Esta nova medida pretende substituir a prática do bailout que tem sido apontada como causa da atual crise da dívida soberana da Zona Euro.
Com este trabalho pretende-se analisar esta nova legislação e, retrospetivamente, aplicá-la ao Banco Espírito Santo (BES), um banco português que foi resolvido a 4 de Agosto de 2014 através de uma medida de separação de ativos. Este exercício tem como objetivo compreender em que consiste o mecanismo do bail-in, de que modo é feita a sua aplicação e, no caso específico do BES analisar quais seriam as diferenças relativamente à resolução que efetivamente ocorreu.
Os resultados encontrados sugerem que a aplicação do mecanismo do bail-in ao BES ter-se-ia traduzido, no pior dos casos, numa poupança de cerca de 60% para o Estado português. Para além disso, apurou-se que era suficiente que os credores do BES suportassem perdas na ordem dos 28% para que não fosse necessária qualquer intervenção ao banco.In the beginning of 2016, the European Commission imposed, in the Eurozone, the bail-in mechanism as a standard procedure to recover and resolve banks which have been weakened by the financial crisis. This new measure intends to replace the bailout practice that has been refered to be associated with the current Eurozone sovereign debt crisis. The purpose of this paper is to study this new banking legislation and, retrospectively, apply it to Banco Espírito Santo (BES), a Portuguese bank which was resolved on 4 August 2014 through an asset separation tool. This exercise endeavours to understand what the bail-in mechanism is, how it is performed and, in the particular case of BES to analyse how it would have been different from the resolution that effectively occurred. The results suggest that the application of the bail-in mechanism to BES would have granted, in the worst case scenario, savings for the Portuguese State of about 60%. In addition, it was observed that it would have been sufficient that the investors of the entity had sustained losses of 28%, in order for the bank not to need any intervention.
