Streszczenie:

What do you do if a computational object fails a specification? An obvious approach is to repair it, namely, to modify the object minimally to get something that satisfies the constraints. In this thesis we study foundational problems of repairing regular specifications over strings and trees. Given two regular specifications R and T we aim to understand how difficult it is to transform an object satisfying R into an object satisfying T. The setting is motivated by considering R to be a restriction -- a constraint that the input object is guaranteed to satisfy -- while T is a target -- a constraint that we want to enforce. We first study which pairs of restriction and target specifications can be repaired with a ``small'' numbers of changes. We formalize this as the bounded repair problem -- to determine whether one can repair each object satisfying R into T with a uniform number of edits. We provide effective characterizations of the bounded repair problem for regular specifications over strings and trees. These characterizations are based on a good understanding of the cyclic behaviour of finite automata. By exploiting these characterizations, we give optimal algorithms to decide whether two specifications are bounded repairable or not. We also consider the impact of limitations on the editing process -- what happens when we require the repair to be done sequentially over serialized objects. We study the bounded repair problem over strings and trees restricted to this streaming setting and show that this variant can be characterized in terms of finite games. Furthermore, we use this characterization to decide whether one can repair a pair of specifications in a streaming fashion with bounded cost and how to obtain a streaming repair strategy in this case. The previous notion asks for a uniform bound on the number of edits, but having this property is a strong requirement. To overcome this limitation, we study how to calculate the maximum number of edits per character needed to repair any object in R into T. We formalize this as the asymptotic cost -- the limit of the number of edits divided by the length of the input in the worst case. Our contribution is an algorithm to compute the asymptotic cost for any pair of regular specifications over strings. We also consider the streaming variant of this cost and we show how to compute it by reducing this problem to mean-payoff games.

Streszczenie:

Recent decades have seen the emergence of calls for financial reparations to African Americans, Caribbean nations and Africa. These claims have sought to utilise legal principles of torts and unjust enrichment to create a causal chain between the history of transatlantic slavery, via colonialism and segregation, to present-day national and international racial inequality. This thesis argues that such conceptualisations of reparations oversimplify the history and legacy of transatlantic slavery, and therefore what is required to repair that history and legacy. The foremost legacy is attitudinal and relational. Modern anti-black racism was developed to justify the institutionalisation of slavery in the New World by Europeans. Racism in turn has, both knowingly and unknowingly, shaped the construction of historical memory and the development of national and international European identity. These identities have in turn shaped the relationships between Europeans and Africans, leading to present-day injustice and racial inequality. To overcome the socioeconomic legacies of transatlantic slavery, reparation must prioritise relational and attitudinal repair. This thesis utilises the theories of restorative justice, and its implementation in truth and reconciliation processes, to argue that museums and schools, by broadening the history they present to include previously suppressed events and community perspectives, can potentially contribute to relational repair at a national level in Britain and the US, and internationally via projects such as UNESCO’s Slave Route Project. This thesis argues that the history of transatlantic slavery and its legacies of relational harm and socioeconomic inequality cannot be isolated or fully understood without a wider historical and present-day contextualisation of inequalities and prejudices, including class. This thesis, therefore, ties the history and legacy of transatlantic slavery firmly into wider national and international history and underlines how confronting historical injustice and its legacy is vital to the creation of a fair and just future.

Streszczenie:

Type systems for programming languages can be used by compilers to reject programs which are found to be unsound and which may, therefore, fail to execute successfully. When a program is rejected the programmer must repair it so that it can be type-checked correctly and then executed safely. Diagnostic error messages are essential to help the programmer repair the program. Hindley-Milner type systems give the programmer a great deal of flexibility (polymorphism and implicit typing) while ensuring type safety. As a consequence of this flexibility repairing mistakes can be difficult and programmers have previously observed that type error messages produced by compilers are not helpful enough. This thesis examines the problem of producing more helpful error messages for ill-typed programs written in programming languages with a Hindley-Milner typing discipline. Three main results are described. Firstly, type inference algorithms which infer types in different orders are described, and the ability of these to produce more meaningful error messages is investigated. Secondly, the results of several other authors on helping to explain type inference are condensed into a single generalisation. Thirdly, error messages which suggest concrete changes to the program to remove type errors are produced using the theory of linear type isomorphisms. This theory is implemented as an extension to the MLj compiler. Finally, extensions to Hindley-Milner are explored, taking the type system of MLj as an example.

Streszczenie:

Huge amount of data flows around the Internet every second, but for the data to be useful at its destination, it must be presented in a way such that the target has little problem interpreting it. Current data exchange technologies may rearrange the structure of data to suit expectations at the target. However, there may be semantics behind data (e.g. knowing the title of a book can determine its #pages) that may be violated after data translation. These semantics are expressed as integrity constraints (IC) in a database. Currently, there is no guarantee that the exchanged data conforms to the target’s ICs. As a result, existing applications (e.g. user queries) that assume such semantics will no longer function correctly. Current constraint repair techniques deal with data after it has been translated; thus take no consideration of the integrity constraints at the source. Moreover, such constraint repair methods usually involve addition/deletion/modification of data, which may yield incomplete or false data. We consider the constraints of both source and target schemas; together with the mapping, we can efficiently detect which constraint is violated and suggest ways to correct the mappings.

Streszczenie:

Companies strive to improve their business processes in order to remain competitive. Process mining aims to infer meaningful insights from process-related data and attracted the attention of practitioners, tool-vendors, and researchers in recent years. Traditionally, event logs are assumed to describe the as-is situation. But this is not necessarily the case in environments where logging may be compromised due to manual logging. For example, hospital staff may need to manually enter information regarding the patient’s treatment. As a result, events or timestamps may be missing or incorrect. In this paper, we make use of process knowledge captured in process models, and provide a method to repair missing events in the logs. This way, we facilitate analysis of incomplete logs. We realize the repair by combining stochastic Petri nets, alignments, and Bayesian networks. We evaluate the results using both synthetic data and real event data from a Dutch hospital.
Unternehmen optimieren ihre Geschäftsprozesse laufend um im kompetitiven Umfeld zu bestehen. Das Ziel von Process Mining ist es, bedeutende Erkenntnisse aus prozessrelevanten Daten zu extrahieren. In den letzten Jahren sorgte Process Mining bei Experten, Werkzeugherstellern und Forschern zunehmend für Aufsehen. Traditionell wird dabei angenommen, dass Ereignisprotokolle die tatsächliche Ist-Situation widerspiegeln. Dies ist jedoch nicht unbedingt der Fall, wenn prozessrelevante Ereignisse manuell erfasst werden. Ein Beispiel hierfür findet sich im Krankenhaus, in dem das Personal Behandlungen meist manuell dokumentiert. Vergessene oder fehlerhafte Einträge in Ereignisprotokollen sind in solchen Fällen nicht auszuschließen. In diesem technischen Bericht wird eine Methode vorgestellt, die das Wissen aus Prozessmodellen und historischen Daten nutzt um fehlende Einträge in Ereignisprotokollen zu reparieren. Somit wird die Analyse unvollständiger Ereignisprotokolle erleichtert. Die Reparatur erfolgt mit einer Kombination aus stochastischen Petri Netzen, Alignments und Bayes'schen Netzen. Die Ergebnisse werden mit synthetischen Daten und echten Daten eines holländischen Krankenhauses evaluiert.

Streszczenie:

Toyota faced a massive international recall crisis in 2009 that threatened to destroy its image in relation to the quality and safety of its vehicles. The majority of Toyota’s recalls were issued in the United States, where Toyota was heavily scrutinized in media coverage. This exploratory study examines media and public relations content to examine how the media framed the crisis, and how Toyota framed image repair efforts during the crisis. It explores the foundations of image and communication, drawing upon William James and Jürgen Habermas, in addition to the theoretical underpinnings of impression management and framing analysis (e.g., Goffman, 1959; 1974), source selection (e.g. Hall et al., 1978), and image repair and crisis communication (e.g., Benoit, 1997; Coombs, 2007). Qualitative framing analysis is employed to code and analyze data sourced from three American newspapers, as well as Toyota U.S.A.’s press releases during the crisis period. The framing analysis revealed the fundamental role of customers and industry experts in defining a crisis when an organization’s credibility is diminished in the media, as well as the strong presence of culturally embedded themes in media framing. Toyota’s recovery was strongly linked to its actions to communicate transparently, remedy the situation, and demonstrate cultural sensitivity to its American customers. Drawing upon the findings, this study provides general recommendations for corporate crisis communication at the various stages of issue management, the crisis, and post-crisis.

Tratamento de exceções e o modo mais comum de lidar com erros no desenvolvimento de software robusto. Tratamento de exceções refere-se ao processo de sinalizar exceções quando erros em tempo de execução são detectados e de tomar ações para responder à ocorrência destas exceções. Apesar de objetivarem a melhoria da robustez de software, sistemas de software ainda são implementados sem se basear em uma política explícita para tratamento de exceções. Cada política define as decisões de projeto que governam como tratamento de exceções deve ser implementado num sistema. Tais políticas não são comumente documentadas e são apenas implicitamente definidas no projeto do sistema. Desta forma, desenvolvedores tendem a introduzir no código fonte violações das políticas implícitas e tais violações comumente causam falhas em sistemas de software. Neste contexto, o objetivo desta tese é apoiar desenvolvedores na detecção e reparação de violações de tratamento de exceções. Para atingir este objetivo, duas soluções complementares foram propostas. A primeira solução é baseada numa linguagem específica de domínio que apoia a detecção de violações ao definir explicitamente políticas de tratamento de exceções que devem ser obedecidas no código fonte. A linguagem proposta foi avaliada num estudo centrado no usuário e num estudo de caso. Com as observações e as experiências coletadas no estudo centrado no usuário, nós identificamos algumas características da linguagem que dificultavam o seu uso e que motivaram novos construtos. Além disso, os resultados do estudo de caso mostraram que violações e falhas costumam ter causas comuns. Portanto, violações de tratamento de exceção podem ser usadas para detectar causas de faltas relacionadas à exceções. Para complementar a detecção de violações, este trabalho também propôs uma solução para apoiar o reparo de violações de tratamento de exceções. Reparar estas violações requer raciocinar sobre o impacto global que mudanças em tratamento de exceções pode ter em diferentes partes do sistema. Desta forma, este trabalho propôs uma estratégia heurística de recomendação que leva em conta o contexto global onde violações ocorrem a fim de produzir recomendações. Cada recomendação produzida consiste em uma sequência de modificações que servem como um plano detalhado de como uma violação de tratamento de exceções pode ser removida do código fonte. A estratégia de recomendação proposta também se beneficia de especificações explícitas de políticas, embora sua disponibilidade não seja obrigatória. Os resultados das nossas avaliações empíricas revelaram que a estratégia de recomendação proposta produziu recomendações capazes de reparar violações em aproximadamente 70 por cento dos casos. Quando especificações de políticas estão disponíveis, a estratégia produziu recomendações capazes de reparar violações em 97 por cento dos casos.
Exception handling is the most common way of dealing with exceptions in robust software development. Exception handling refers to the process of signaling exceptions upon the detection of runtime errors and taking actions to respond to their occurrence. Despite being aimed at improving software robustness, software systems are still implemented without relying on explicit exception handling policies. Each policy defines the design decisions governing how exception handling should be implemented in a system. These policies are often not documented and are only implicitly defined in the system design. Thus, developers tend to introduce in the source code violations of implicit policies and these violations commonly cause failures in software systems. In this context, the goal of this thesis is to support developers in detecting and repairing exception handling violations. To achieve this goal, two complementary solutions were proposed. The first solution is based on a domain-specific language supporting the detection of violations by explicitly defining exception handling policies to be enforced in the source code. The proposed language was evaluated with a user-centric study and a case study. With the observations and experiences gathered in the user-centric study, we identified some language characteristics that hindered its use and that motivated new language constructs. In addition, the results of the case study showed that violations and faults in exception handling share common causes. Therefore, violations can be used to detect potential causes of exceptionrelated failures. To complement the detection of exception handling violations, this work also proposed a solution for supporting the repair of exception handling violations. Repairing these violations requires reasoning about the global impact that exception handling changes might have in different parts of the system. Thus, this work proposed a recommender heuristic strategy that takes into account the global context of where violations occur to produce recommendations. Each recommendation produced consists of a sequence of modifications that serves as a detailed blueprint of how an exception handling violation can be removed from the source code. The proposed recommender strategy also takes advantage of explicit policy specifications, although their availability is not mandatory. The results of our empirical assessments revealed that the proposed recommender strategy produced recommendations able to repair violations in approximately 70 per cent of the cases. When policy specifications are available, it produced recommendations able to repair violations in 97 per cent of the cases.

In this paper, we develop a scheme to recover a single erasure when using a Cartesian code,in the context of a distributed storage system. Particularly, we develop a scheme withconsiderations to minimize the associated bandwidth and maximize the associateddimension. The problem of recovering a missing node's data exactly in a distributedstorage system is known as theexact repair problem. Previous research has studied theexact repair problem for Reed-Solomon codes. We focus on Cartesian codes, and show wecan enact the recovery using a linear exact repair scheme framework, similar to the oneoutlined by Guruswami and Wooters in 2017.

Distributed storage systems are systems which store a single data file over multiple storage nodes. Each storage node has a certain storage efficiency, the "space" required to store the information on that node. The value of these systems, is their ability to safely store data for extended periods of time. We want to design distributed storage systems such that if one storage node fails, we can recover it from the data in the remaining nodes. Recovering a node from the data stored in the other nodes requires the nodes to communicate data with each other. Ideally, these systems are designed to minimize the bandwidth, the inter-nodal communication required to recover a lost node, as well as maximize the storage efficiency of each node. A great mathematical framework to build these distributed storage systems on is erasure codes. In this paper, we will specifically develop distributed storage systems that use Cartesian codes. We will show that in the right setting, these systems can have a very similar bandwidth to systems build from Reed-Solomon codes, without much loss in storage efficiency.

Streszczenie:

The current state of the global distribution of income, wealth, and well-being is in many respects the product of historical acts and processes. Of these, some have been just, others not. In philosophical discourse, processes of the latter kind are referred to as historical injustices. Of these historical injustices, the most protracted, extensive, and (presumably) the most devastating, is colonialism. For centuries, innocent people – in fact whole continents – were subjected to plunder, despoilment, land-displacement, exploitation, slavery, oppressive rule, cultural rape, and genocide. The extent and persistence of the consequences of this particular historical injustice are, however, contested territory. With regards to the exact causes of global poverty and destitution, measuring the effects of colonialism vis-à-vis other determining factors is an empirical impossibility. Nonetheless, it is beyond dispute that during colonial times vast amounts of riches were illicitly transferred from the colonies to their (mainly European) masters. It therefore seems reasonable to assume that this massive and prolonged one-directional transfer (from South to North) of wealth and resources necessary for nation-building, i.e. self-sustained and successful eco¬nomic development, has contributed, to a morally significant degree, to the unequal economic status of societies – resulting, ultimately, in the present unjust division of countries into developed, industrialized ones on the one hand, and under-developed (in many cases, extremely poor) ones, on the other. If this assumption is correct, then this is a problem of fantastic moral proportions.

The aim of this essay is to consider the moral implications of the consequences of colonialism in light of the problem of global poverty and against emergent, compelling theories of global justice. It is argued that the former colonies are justified in making reparative demands on their former colonial powers as a matter of rectificatory justice. The demands discussed here are aimed at property restoration and economic compensation. The salience of these demands is established by way of arguments for collective moral responsibility and historical (trans-generational) obligations. It is further argued that such reparations would constitute a great leap towards eradicating global poverty on the grounds that many presently poor countries were the victims of colonial atrocities. Such a leap would also take us closer to a just world.

Objective: To analyze what information skills medical residents have in PDA use, evidence-based medicine (EBM), Loansome Doc use, and off-campus access to databases. Methods: A survey analysis was conducted of 217 medical residents from the 2005/06 East Tennessee State University Quillen College of Medicine class in surgery, family medicine, internal medicine, obstetrics/gynecology, psychiatry, pediatrics, and pathology with a return rate of 48.4%. Quantitative analysis was performed with the SPSS (v. 14.0 for Windows) software program. The results were expressed in percents in graphical or tabular form. The data were analyzed using descriptive statistics (frequencies, mean, median, and mode), and inferential statistics (Mann-Whitney U test and chi-square test.) Results: On a Likert-type scale of 1–7, medical residents rated their PDA skills at a mean of 5.11. By the KruskalWallis Analysis of Variance statistic, there were no signifi - cant differences between residency programs. By use of the Mann-Whitney U Test statistic, it was determined that there was no statistically signifi cant difference between the PDA skills or residents and their attendings. On a Likert-type scale of 1–7, medical residents rated their EBM skills at a mean of 4.82. There was a signifi cant differences between residency programs as determined by the Kruskal-Wallis Analysis of Variance statistic. Residents were infrequent Loansome Doc users, and a disturbing 49.5% did not know how to access medical databases from off-campus. Conclusions: Residents need more training by medical librarians in the clinical information skills of PDA use, EBM, Loansome Doc, and off-campus access.

Streszczenie:

Prior research has shown the therapeutic alliance to be positively related to therapeutic outcome in couple therapy (Johnson & Talitman, 2007; Knoblock-Fedders, Pinsoff, & Mann, 2007). It is common for the therapeutic alliance to vary over the course of therapy. Alliance ruptures can be defined as â deteriorations in the relationship between therapist and patientâ (Safran & Muran, 1996, p. 447). If managed successfully, these moments of alliance rupture can positively impact therapy (Safran & Muran, 1996; Sprenkle, Davis, & Lebow, 2009). As a result, researchers have begun to develop models of alliance rupture repair to help further our understanding of how this process is achieved in various therapeutic approaches (Aspland, Llewelyn, Hardy, Barkham, & Stiles, 2008; Binder, Holgerse, & Nielsen, 2008; Safran & Muran, 1996). The purpose of this study was to conduct a preliminary, discovery-oriented task analysis (Greenberg, 2007) in order to develop a model of alliance rupture repair in Emotionally Focused Therapy (EFT), a couple therapy approach which encourages emotional reconnection and restructuring of couple interactions developed by Susan Johnson and Les Greenberg (Johnson, 2004). By conducting a thought experiment with four experienced certified EFT therapists, a rational model of alliance rupture repair in EFT was formulated. The rational model was then compared with the analysis of alliance rupture repair sequences during the process of one coupleâ s therapy with a certified EFT therapist to develop a rational-empirical model of alliance rupture repair in EFT. The final model and treatment implications are discussed.

Streszczenie:

The problem: In Australia, over 12,000 people live with a spinal cord injury (SCI) and at least one new case occurs every day. Currently, there is no effective treatment for SCI. Transplantation of olfactory ensheathing cells (OECs; the glial cells of the primary olfactory nervous system) is a promising therapy, in particular autologous transplantation. OECs exhibit unique properties which stimulate neuronal growth and axonal extension, including structural and neurotrophic/guidance support. OECs also function as immune cells and remove (phagocytose) cell debris from the injury site. Furthermore, OECs migrate across the injury site and provide support for regenerating axons. However, functional outcomes in both animal studies and human clinical trials vary greatly, and there are key obstacles in this therapy. These include insufficient cell proliferation rate (both prior to transplantation and after transplantation), cell migration rate and phagocytic activity. If these cell behaviours could be stimulated, the therapeutic potential of OECs would be significantly enhanced. Another important avenue for improvement is the development of novel three-dimensional (3D) cell constructs suitable for both pre-transplantation work (cell culture and drug screening) and for transplantation of OECs directly as a 3D structure into the nervous system injury site. In summary, this work has (1) identified three natural compounds with potential to promote favourable OEC behaviours relevant for neural repair, and (2) led to the development of a novel 3D culture system in which cells rapidly self-assemble without any added ingredients, applicable to a wide range of neural repair avenues. Thus far, the outcomes of this thesis have led to two patent applications, two first-author publications, three first-author manuscripts in submission/preparation, and 1 patent application in preparation, as well as contributing to four papers/manuscripts led by other researchers in the Clem Jones Centre for Neurobiology and Stem Cell Research. The future directions towards enhancing the outcomes of OEC transplantation will be based on the combination of the identified natural products and the developed NLM/NLMNB 3D cell culture methods.

Streszczenie:

La migration de données entre des sources aux schémas hétérogènes est un domaine en pleine croissance avec l'augmentation de la quantité de données en accès libre, et le regroupement des données à des ﬁns d'apprentissage automatisé et de fouilles. Cependant, la description du processus de transformation des données d'une instance source vers une instance déﬁnie sur un schéma diﬀérent est un processus complexe même pour un utilisateur expert dans ce domaine. Cette thèse aborde le problème de la définition de mapping par un utilisateur non expert dans le domaine de la migration de données, ainsi que la vérification du respect par ce mapping des contraintes d'accès ayant été définies sur les données sources. Pour cela, dans un premier temps nous proposons un système dans lequel l'utilisateur fournit un ensemble de petits exemples de ses données, et est amené à répondre à des questions booléennes simples afin de générer un mapping correspondant à ses besoins. Dans un second temps, nous proposons un système permettant de réécrire le mapping produit de manière à assurer qu'il respecte un ensemble de vues de contrôle d'accès définis sur le schéma source du mapping. Plus précisément, le premier grand axe de cette thèse est la formalisation du problème de la définition interactive de mappings, ainsi que la description d'un cadre formel pour la résolution de celui-ci. Cette approche formelle pour la résolution du problème de définition interactive de mappings est accompagnée de preuves de bonnes propriétés. A la suite de cela, basés sur le cadre formel défini précédemment, nous proposons des algorithmes permettant de résoudre efficacement ce problème en pratique. Ces algorithmes visent à réduire le nombre de questions auxquelles l'utilisateur doit répondre afin d'obtenir un mapping correspondant à ces besoins. Pour cela, les mappings possibles sont ordonnés dans des structures de treillis imbriqués, afin de permettre un élagage efficace de l'espace des mappings à explorer. Nous proposons également une extension de cette approche à l'utilisation de contraintes d'intégrité afin d'améliorer l’efficacité de l'élagage. Le second axe majeur vise à proposer un processus de réécriture de mapping qui, étant donné un ensemble de vues de contrôle d'accès de référence, permet d'assurer que le mapping réécrit ne laisse l'accès à aucune information n'étant pas accessible via les vues de contrôle d'accès. Pour cela, nous définissons un protocole de contrôle d'accès permettant de visualiser les informations accessibles ou non à travers un ensemble de vues de contrôle d'accès. Ensuite, nous décrivons un ensemble d'algorithmes permettant la réécriture d'un mapping en un mapping sûr vis-à-vis d'un ensemble de vues de contrôle d'accès. Comme précédemment, cette approche est complétée de preuves de bonnes propriétés. Afin de réduire le nombre d'interactions nécessaires avec l'utilisateur lors de la réécriture d'un mapping, une approche permettant l'apprentissage des préférences de l'utilisateur est proposée, cela afin de permettre le choix entre un processus interactif ou automatique. L'ensemble des algorithmes décrit dans cette thèse ont fait l'objet d'un prototypage et les expériences réalisées sur ceux-ci sont présentées dans cette thèse
Data exchange between sources over heterogeneous schemas is an ever-growing ﬁeld of study with the increased availability of data, oftentimes available in open access, and the pooling of such data for data mining or learning purposes. However, the description of the data exchange process from a source to a target instance deﬁned over a diﬀerent schema is a cumbersome task, even for users acquainted with data exchange. In this thesis, we address the problem of allowing a non-expert user to spec- ify a source-to-target mapping, and the problem of ensuring that the speciﬁed mapping does not leak information forbidden by the security policies deﬁned over the source. To do so, we ﬁrst provide an interactive process in which users provide small examples of their data, and answer simple boolean questions in order to specify their intended mapping. Then, we provide another process to rewrite this mapping in order to ensure its safety with respect to the source policy views. As such, the ﬁrst main contribution of this thesis is to provide a formal deﬁnition of the problem of interactive mapping speciﬁcation, as well as a formal resolution process for which desirable properties are proved. Then, based on this formal resolution process, practical algorithms are provided. The approach behind these algorithms aims at reducing the number of boolean questions users have to answers by making use of quasi-lattice structures to order the set of possible mappings to explore, allowing an eﬃcient pruning of the space of explored mappings. In order to improve this pruning, an extension of this approach to the use of integrity constraints is also provided. The second main contribution is a repairing process allowing to ensure that a mapping is “safe” with respect to a set of policy views deﬁned on its source schema, i.e., that it does not leak sensitive information. A privacy-preservation protocol is provided to visualize the information leaks of a mapping, as well as a process to rewrite an input mapping into a safe one with respect to a set of policy views. As in the ﬁrst contribution, this process comes with proofs of desirable properties. In order to reduce the number of interactions needed with the user, the interactive part of the repairing process is also enriched with the possibility of learning which rewriting is preferred by users, in order to obtain a completely automatic process. Last but not least, we present extensive experiments over the open source prototypes built from two contributions of this thesis

Nanotechnology underwent a very rapid development in the last decades, thanks to the invention of different techniques that allow reaching the nanoscale. The great interest in this area arises from the variety of possible applications in different fields, such as electronics, where the miniaturization of components is a key factor, but also medicine. The creation of smart systems able to carry out a specific task in the body in a controlled way, either in diagnosis or therapy or tissue engineering, is the ultimate goal of a newborn area of research, called nanomedicine. In fact, to reach such an outstanding objective, a nanometer‐sized material is needed and carbon nanotubes (CNTs) are among the most promising candidates. The aim of this thesis was to study this opportunity and, in particular, the possible application of carbon nanotubes for spinal network repairing. After a review of the main features of neuronal network systems and the most common techniques to study their functionality, possible applications of nanotechnology for nanomedicine purposes are considered, focusing the attention on CNTs as neuronal interface in nerve tissue engineering. The work can be divided into two big parts. In the first part the impact of carbon nanotubes on various neuronal systems was studied. Different form of carbonaceous materials (carbon nanotubes, nanohorns and graphene) were deposited in a homogeneous way on a glass surface playing with organic functionalization and different deposition techniques. Hippocampal neuronal cells were grown on their surface to better understand how morphology and conductivity of the material could influence the activity of the neuronal network evidencing how both these characteristics could affect the electrophysiological properties of neurons. Then, also spinal neurons were grown on carbon nanotubes network deposited on a glass substrate to evaluate, for the first time, the impact of carbon nanotubes on this kind of cells. The tight interaction between these two materials appeared to cause a faster maturation of the spinal neurons with respect II to the control grown on a glass substrate. The long-term impact on a complex tissue (spinal cord slice) grown on carbon nanotubes carpet was also studied. The intimate interaction between the two materials observed by TEM and SEM analysis caused an increase in dimensions and number of neuronal fibers that comes out from the body of a spinal cord slice. An increase in electrophysiological activity of all neuronal network of the slice was also reported. In the second part of the work different conductive biocompatible nanocomposite materials based on carbon nanotubes and “artificial” polymers (such as Nafion, PVA, PET, PEI, PDMS and PANI) were investigated. The idea is to test these materials as neuronal prosthesis to repair spinal cord damage. All the prepared scaffolds showed CNTs on the surface favoring CNTs-neurons interaction. To address this aim different techniques and different organic functionalizations of CNTs were utilized to control supramolecular interactions between the nanomaterial and polymers orienting the deposition of the CNTs and preventing their aggregation. After that, an innovative method to study the possible ability of this nanocomposite materials to transmit a neuronal signal between two portions of spinal cord was designed. Functionalization of gold surfaces with thiolated carbon nanotubes have been conducted in order to develop suitable devices for neuronal stimulation and consequent spinal cord lesions repairing. In particular thiol groups were introduced on the graphitic surface of carbon nanotubes by means of covalent functionalization. First of all, the interaction of CNTs with gold nanoparticles has been evaluated, then a gold surface has been coated by means of contact printing technique with a homogeneous film of CNTs. This hybrid material could be useful to produce innovative electrodes for neuronal stimulation

Streszczenie:

Bakgrund: Redovisningsskandaler anses grunda sig i de kryphål som återfinns inom redovisningens regelverk. När dessa kryphål utnyttjas riskerar organisationens redovisnings legitimitet att ådra sig en legitimitetsskada eftersom den då strider mot allmänhetens förväntningar om hur en korrekt redovisning är upprättad. Tidigare forskning har presenterat strategier för att reparera legitimitet på en organisatorisk nivå. Forskningen tycks däremot vara tunn om hur ett legitimitetstillskrivande medel såsom redovisningen kan repareras när det ådragit sig en legitimitetsskada. Det förklarar varför det varit motiverat att genomföra en studie som undersöker detta. Syfte: Studien syftar till att skapa en modell som förklarar den process där redovisningens legitimitet repareras. Metod: Syftet har besvarats genom en deduktiv ansats där befintlig legitimitetsreparerande litteratur legat till grund för en tentativ modell. Utifrån teori har vi härlett tre mekanismer som vi prövat om de kan förklara hur redovisningens legitimitet repareras. Genom studiens kvalitativa ansats har vi, med hjälp av innehållsanalyser, utfört två fallstudier där fallen avsett två redovisningsskandaler. Med hjälp av empiri bestående av nyhetsartiklar och årsredovisningar, har vi provat om modellen ger en förklaring till hur redovisningens legitimitet repareras. Resultat och slutsats: Studiens resultat pekar mot att vår slutgiltiga modell besvarar syftet. Redovisningens legitimitet kan repareras genom framförallt organisationens egna vidtagna åtgärder, men även genom att såväl organisationen som media utpekar syndabockar som ställs ansvariga för redovisningens brister. Vår slutmodell förklarar även att media har en inverkande och pådrivande roll ifråga om redovisningens legitimitet och att regler och policys skapar möjligheter för organisationen att utnyttja dessa för att legitimera redovisningen.
Background: Accounting scandals are considered based on the loopholes found in the accounting rules. It is argued that an organization's legitimacy in the accounting, in such situations when these loopholes are exploited, can be threatened since it differs from the public's expectations of how a proper accounting is constituted. Previous research has presented strategies to repair organizational legitimacy. Research seems however to be sparse in the matter of how a tool to repair legitimacy, such as accounting, can be repaired when it incurs a loss of legitimacy. This study contributes to this specific area. Purpose: This study aims to create a model that explains the process by which accounting legitimacy is repaired. Method: Through a deductive approach, in which existing literature formed the basis for a tentative model, we derived three mechanisms that have been tested whether they can explain how the legitimacy of accounting can be repaired. Further, by using the techniques of content analysis, we did a dual case study where the cases concerned two Swedish accounting scandals. Using empirical material consisting of news articles and annual reports, we tested whether the model provides an explanation for how the legitimacy of accounting is repaired. Results and conclusions: This study's results suggest that our purpose can be answered. The results also indicates that accounting's legitimacy can be repaired primarily through the organization's own actions taken, but also by the organization as well as the media designate scapegoats who are deemed to be responsible for the accounting's shortcomings. Our final model also explains that media plays an influencing and actuating role in terms of the legitimacy of accounting, and that rules and policies create opportunities for the organization to legitimize its own accounting.

The purpose of this thesis is to explore the adoption of cementitious materials in Taiwan, currently used in repairing reinforced concrete, and then to explain the effectiveness how use of cementitious materials. In the last few years wrecks a natural disaster, creates the massive structure damage, simultaneously to coordinate the topic which the present government impels to continue forever positively to manage, therefore the reinforced concrete structure's repair and maintenance and the reinforcement are worth taking seriously. The major influencing repairing reinforced concrete adopting such cementitious materials are in aspects of environment, and innovation technology characteristics. The samples included 3 damage type: Cracking、Scaling、Spalling-Pothole. After one year experiment period, the 3 damage concretes were treated in injecting, grouting and patching for repairing. The results show that in environment characteristics, Whenever bad quality concrete or workmanship is applied, concrete may start to crack, delaminate or spall due to physical or chemical causes a short time after casting.. In repair technology, “Damaged condition” and “increase anticorrosive material” is highly correlated with repairing cementitious Materials of reinforced concrete.

Twelve reinforced concrete corbels were tested twice in this study. Parameters of the shear span-to-depth ratios and the area of carbon fiber reinforced plastics (CFRP) are covered in this study. Corbels were tested till shear-failure during the first load stage. After the first load stage, four corbels were repaired by CFRP; eight corbels were repaired by EPOXY using low pressure injection method. Retest on the repaired corbels was performed during the second load stage. The test results at the first load stage indicate that shear span-to-depth ratio is the most important parameter on the shear strength of corbels. The larger the shear span-to-depth ratio the smaller the shear strength of corbels is. The larger the area of CFRP the higher the shear strength of corbels is. The test results at the second load stage indicated that the larger the shear span-to-depth ratio the smaller the shear strength of corbels is. Since the mean of the repair index is less than unity, the repairing cannot raise the shear strength of corbels.

Explanation-based learning occurs when something useful is retained from an explanation, usually an account of how some particular problem can be solved given a sound theory. Many real-world explanations are not based on sound theory, however, and wrong things may be learned accidentally, as subsequent failures will likely demonstrate. In this paper, we describe ways to isolate the facts that cause failures, ways to explain why those facts cause problems, and ways to repair learning mistakes. In particular, our program learns to distinguish pails from cups after making a few mistakes.

The full adder (FA) is a critical part of these processors for growing portable systems with high-performance. As feature size of CMOS technology scaling down, reliability becomes important issue of IC design. Fault tolerant technology is to prevent system failure while transient fault occurred at a circuit node; some systems are designed to be reconfigurable and self-repairing. In this thesis, proposed a self- repairing full adder based on parity, and design a totally self-checking checker to improve the reliability of the circuit. The self-repairing full adder has superior features with 56 transistor count, 100% area overhead, 38% time overhead, 1.065uW power dissipation, 0.197fJ power delay product and maximum speed up to 1G Hz. The experimental results show the proposed self-repairing full adder design is valid and practical.

The availability is the basis of managing logistics. After probing into the past theoretical literatures on availability, we discover that to promote the availability is mainly to improve the repairing procedures. Thus, the computer software, eM-Plant 5.5, is employed to build a simulation model, which reveals the real system and is conducted to find out the relationship between the resources allocation and the availability. Sensitivity analysis is used to ease off the bottlenecks of that procedure. As the results, first, when we propose the 2nd scenario to increase throughput from 132 to 203, we promote the overall availability from 87.45% to 91.45%. Secondly, when we take the technical maturity into consideration, we apparently ease off those bottlenecks with the 3rd, 4th, and 5th scenarios under the same resources constraint: In the 3rd scenario, the utilization of main-part workbench falls about 10% and that of subsidiaries workbench falls about 11%; in the 4th scenario, that of main-part workbench falls about 9% and subsidiaries about 11%. Finally in the 5th scenario, main-part 7% and subsidiaries still 11%. Among these scenarios, the other workbenches would not produce new bottlenecks. With regard to which scenario is the most beneficial to the unit, it depends on the superior’s choice.

Decaying urban spaces are common in post-industrial New England. When manufacturing activities withdrew from New England they left holes in the urban fabric. Physical absence of these former economic drivers is easy to note in empty mill buildings, warehouses, and storefronts. Farther reaching impacts of this exodus are less apparent. Jobs went with manufacturing. Raw materials needed to be harvested and made available to manufacturers; the finished products needed to be distributed, sold, and moved; supporting businesses provided for these needs. Many other groups supported manufacturing; some through the management of the companies, some catered to workers’ needs, or the needs of workers’ children and families. This network of groups and individuals connected to industry made up vibrant communities in the heyday of manufacturing in New England. When manufacturing left many of the groups providing support functions collapsed. Many people moved away, or if they stayed they were left unemployed or underemployed. Whole communities were damaged when manufacturing left New England. Many have not yet fully recovered. The goal of this thesis is to propose a path toward the revitalization and repair of the urban fabric of depressed post-industrial communities in New England. Many post-industrial New England communities have lost their identity. These places have empty buildings, empty lots, and their main streets, former “downtowns,” are quiet. There is little to recommend these areas as a place to be. These depressed and decaying places need revitalization. They are no longer centers of manufacturing or industry; they need a new identity, one that reflects what they are now and what they would like to become in the future. Revitalization should be grounded in a study of the unique place it addresses. There are communities and inhabitants present in even the most depressed places. These groups need to be recognized and their needs identified before revitalization can be undertaken. Revitalization should be inclusive. Residents should feel encouraged to stay in, and be proud of, their community. Revitalization should be sustainable; socially, ecologically and economically. If revitalization of a depressed area calls for attracting more residents and businesses, those targeted to inhabit the revitalized space should fit into the existing community, not displace it. This thesis proposes a revitalization of a depressed post-industrial area of Millers Falls, Massachusetts in the vicinity of East Main and Bridge Streets. This revitalization proposal will be carried out within a framework of study of place, inclusivity, and holistic sustainability.

Most system-on-chip (SoC) designs have many memory cores. These memory cores usually occupy most of the chip area. Thus the yield of memory cores usually dominates the yield of SoCs. Built-in self-repair (BISR) technique is gaining popular for improving the yield of memory cores. In this thesis, we propose an efficient BISR scheme for repairing multiple memory instances in SoCs. The BISR scheme can support two types of redundancy organizations (i.e., spare rows/spare columns and spare rows/spare IOs). Experimental results show that the area overhead of the proposed BISR is about 2.19% for an 8K×64-bit memory with two spare rows and four spare columns. Also, the repair rate of the proposed RA algorithm is close to the repair rate of the exhaustive algorithm. We also present an infrastructure intellectual-property (IIP) for testing and repairing embedded memories. The IIP is composed of an instruction memory, a BISR processor and various wrappers for different memory sizes. The IIP can test multiple memory instances with different sizes concurrently in an SoC. It also can execute diagnosis and various redundancy analysis algorithms. The execution time of memory test and repair can be reduced significantly by using the defined instruction set. Compared with the processor-based BISR scheme [20], the test time of the proposed IIP is greatly reduced. Also, the flexibility of proposed IIP is higher than traditional dedicated BISR schemes. Experimental results show that the test time of executing local repair-most (LRM) algorithm [16] is 2320Nf cycles, where Nf is the number of faulty words. In the proposed IIP, it only needs (NSR+NSC+NSF)Nf cycles, where NSR (NSC) is the number of spare rows (columns) and NSF is the number of cycles of shifting the repair information from the Wrapper to the BISR Processor which is equal to . The area of the BISR Processor of the proposed IIP is about 6926 gates for a memory with three spare rows and threes spare columns. The area overhead of the Wrapper of the proposed IIP is about 2.84% for an 8K×64-bit memory with the three spare rows and three spare columns.

Reactive repair of a disrupted schedule is a better alternative to total rescheduling, as the latter is a time consuming process and also results in shop floor nervousness. The schedule repair heuristics reported in the literature generally address only machine breakdown. This paper presents a modified Affected Operations Rescheduling (mAOR) approach, which deals with many of the disruptions that are frequently encountered in a job shop. The repair of these disruptions has been decomposed into four generic repair actions that can be applied singularly or in combination. These generic repair actions are evaluated through a simulation study with the performance measures of efficiency and stability. The results indicate the effectiveness of the mAOR heuristic in dealing with typical job shop disruptions.

Due to the economic boom in Taiwan in recent years, transportation and communication increases daily and the airport pavement load also becomes heavier. How to maintain and extend the life of pavement has now become one of the major topics in the transportation engineering department. However, since air cargo is almost at its saturation, it is not advisable to close the airport for a long period of time to repave the field. Therefore, how to repair the distressed pavement in time and effectively has now become the major issue of maintaining the pavement at the airport effectively. Repair of distressed pavement at the airport in Taiwan at present mostly relies on the accumulated experience of repair experts or on the repair material suggested by the material supplier(s). There is still no set of perfect and practical pavement repair criteria to be followed. The main reason for poor pavement repair at the airport in Taiwan was that repairs were done without understanding and diagnosing the cause of distress or adopting improper repair method and materials. Also, it lacks a complete file record after repairing the pavement, so there is no way of accumulating repair experience and unable to evaluate the results of repair methods and materials. As a result, there is frequent repetitious repair failure, which is also one of the main reason of poor pavement repair at the airport in Taiwan. The purpose of this study is to create an airport pavement repair system, that is able to process, store, and show the attribute data and spatial data of airport pavement by collecting and integrating the knowledge and experience of airport pavement repair experts. First, fuzzy logic was applied to do the inferring, based on the knowledge of experts, and create a fuzzy inferring mode of diagnostic expert system for the cause of pavement distress at the airport, to enable the system to process uncertain problems of experts on the degree of rigid pavement distress at the airport, in order to improve the restrictions on conventional expert system and thus diagnose a more rational and accurate cause. The machine learning of neural network theory was also applied in the experts’ questionnaire survey, and then study and classify the cases in order to accumulate the knowledge for the advantage of giving suggestions to repairs on field distress in the future and be able to choose an appropriate plan in order to ensure effect of pavement service. Innovative and appropriate repair materials were also taken in account. The function of feedback learning on repair materials was simultaneously created in this study to enable the system to keep on learning any time in order to ensure the suitability of repair materials. In this study a set of GIS & GPS pavement survey method was also developed to conduct a total and temporary pavement survey on the airport pavement in order to deal with the characteristic of business operation at the airport. Initially the airport pavement repair system that was constructed in this study already has the function of diagnosing the cause of pavement distress, suggesting repair plan, and storing and showing the subsequent repair records of each block. Upon practical field application, the pavement survey method developed is more convenient and faster than the conventional pavement survey method.

Manitoba Hydro owns and operates 12 river hydroelectric generating stations ans two major control structures. The structures control the flow of water almost exclusively with gate wheels. It is important for the roller paths to remain true to allow uniform distribution of the hydraulic load on the gates to the gate wheels. Manitoba Hydro is currently replacing the distorted steel roller paths at its MacArthur Generating Station. The purpose of this study was to evaluate the physical properties of high strength proprietary grouts to determine their adequacy for use beneath new roller paths of water control gates which have unusual spacial constraints. Two full size mockups of a portion of an existing guide, with a steel overlay, were utilized in the experimental study. To investigate the stress-strain distribution in the mockup under specific loading condition, strain gauges were installed on both of the web sides of the embedded steel I-beam: one group of gauges was located just below the flange, the others were located along the mid-hight of the beam web. Force gauges were inserted to measure the pressure between the thin grout layer bottom and the top of the embedded I-beam. A special LVDT (linear variable differential transducer) assembly was made to measure the maximum displacement of grout layer. Mockup samples were subjected to static and cyclic loading procedures at two designated loading points. The grout cylindrical creep tests were conducted at the same time. It included tests at room temperature and at the elevated temperature of 50°C. The initial sustained load was 50% of the ultimate compression strength of the grout cylinder (3"x6"). Once the creep development was observed to become constant, the sustained load was raised up to 70% of ultimate strength and held constant until the end of the test. The test results indicate that the strength of the proposed grouting material is adequate to resist the required load, both statically and cyclically. Temperature has no significant effects on this specific loading situation. The proposed grouting method is proven to be simple, economic and efficient, therefore, the technique is suitable for roller path repairing.

ABSTRACT In this study, recast column method is used to retrofit RC frames damaged by short column effect. Four full-scale RC frames, including one prototype frame without bracing, three frames using different types of steel bracing to enhance strength and stiffness, were tested under cyclic loading. In addition to bracing, fiber reinforced plastic (FRP) is used to wrap the columns to enhance ductility. Experimental result shows that the ductility and strength of prototype frame wrapped by FRP sheet are improved better than that of undamaged frame, but stiffness descends explicitly because of damage. In the other hand, the other tree frames using steel bracing performance well in ductility, strength and stiffness. The force-displacement curve of each specimen was also predicted by the SAP2000 code and can match the experimental results quite well. This study demonstrates that steel bracings cut out with holes can efficiently increase both strength and stiffness without reducing ductility. One may control the size of holes to satisfy requirement. With wrapping columns by FRP sheet, the performance of frame system can be substantially increased after retrofit.

QualWeb is an existing tool that evaluates Web pages’ compliance with WCAG 2.0 HTML techniques. We wanted to enhance this tool’s functions by adding a CSS module. For this we intend to create a CSS module, to extend the evaluation process, so that it evaluates HTML and stylesheets, but also to present the user solutions for every evaluation problem. In this report we present the different development stages that our CSS evaluation and repair module went through. We describe how we interpreted the WCAG 2.0 techniques and how we turned them into code; how we processed every CSS rule in a .html document and how we established the connection between the different HTML elements and their CSS rule; how we build the repair process itself and how we managed to present it in an online user interface. One of this stages includes an experimental study where we presented to a set of twenty Web developers, with different levels of HTML knowledge, our developments in order to obtain some feedback on how we were doing. In the corresponding chapter we describe our study and show how presenting repair suggestions for accessibility problems, helps users feel less lost and more self-assured when using our tool. These findings will build ground for a future complete repair module for QualWeb and open way for further enhancements of this Web Accessibility evaluation tool.
A Web é hoje em dia a plataforma mais utilizadas para partilha de conhecimento e divulgação de serviços. A sua crescente importância nota-se aos mais diferentes níveis da nossa sociedade. Universidades, governos, empresas e outras entidades todas aproveitam da facilidade de chegar ao destinatário através da Web. No entanto, o problema surge dado o facto de que nem todos aqueles, a quem este conhecimento e estes serviços se destinam, têm as mesmas capacidades, cognitivas ou físicas. Grupos sociais de indivíduos com dificuldades cognitivas e físicas acabam por ficar à margem destas potencialidades da Web. Apesar de existirem já inúmeras tecnologias de ajuda para estas pessoas, como leitores de ecrã, etc., para que estas funcionem corretamente, é necessário que a informação seja disponibilizada adequadamente formatada. De forma a colmatar estas e outras situações existe a necessidade de normas cujo objectivo seja estandardizar conteúdos desenvolvidos para a Web. A acessibilidade Web é uma preocupação da qual surgem os princípios de inclusão social. E graças à qual, inúmera documentação e tecnologias, têm surgido de forma a colmatar este problema. Entre elas, tecnologias automáticas de avaliação e até de reparação de Acessibilidade Web. Contudo, muitas dessas tecnologias ainda não conseguem colmatar dificuldades que surgem do desenvolvimentos tecnológico da Web. Novas tecnologias, como Javascript, tornam os conteúdos Web em mais do que simples apresentações de texto. Conteúdos Web passam a ser dinâmicos, graças à execução ao de chamadas aos servidores, paralelas à apresentação das páginas Web. Estas interações com o servidor permitem a alteração dos conteúdo nas páginas Web. A avaliação da acessibilidade destes novos conteúdos dinâmicos, não pode ser verificada utilizando os mesmos padrões usados até agora. Caso isto aconteça estes avaliadores de conteúdos estáticos, podem levar a conclusões incompletas que podem mesmo ser incorretas. A ferramenta QualWeb é uma ferramenta de avaliação de Acessibilidade Web. No entanto, ao contrário das mencionadas anteriormente, recorrendo a tecnologias recentes, esta ferramenta permite avaliar aplicações Web dinâmicas. Avaliações de acessibilidade realizadas por esta ferramenta seguem normas internacionais WCAG 2.0 graças à implementação de um modulo de técnicas HTML. No entanto existe ainda espaço para expandir o âmbito desta ferramenta. As normas WCAG 2.0 englobam não apenas o HTML mas também um conjunto de outras tecnologias de entre as quais o CSS. Sendo que, com o crescimento da Web e da quantidade de conteúdos disponíveis online, maior atenção tem sido atribuída à utilização de estilos que possibilitam aos developers desenvolver conteúdos mais apelativos. Por este motivo a sua utilização tem aumentado e os CSS são hoje em dia, considerados como uma das tecnologias mais importantes para a Web. Data esta importância, este trabalho pretende expandir o funcionamento de ferramenta QualWeb, introduzindo lhe novas capacidades anívels dos CSS. Para isso incluímos um módulo de avaliação e reparação de CSS. Esta avaliação, tal como a já existente avaliação de HTML, segue as t´técnicas CSS WCAG 2.0. Não só nos preocupámos em manter a modularidade da ferramenta, mas também nos preocupámos em torna-la ainda mais flexível. As avaliações de HTML seguiam uma determinada forma de execução¸ ao de comprometia a flexibilidade da apresentação de resultados ao developer. Foi por este motivo que decidimos também alterar a perspectiva de apresentação dos resultados,. Esperamos assim melhorar o workflow do developer bem como, a sua experiencia com a nossa ferramenta. Considerando que a complexidade das páginaWeb tem vindo a aumentar, o tempo que um developer poderá eventualmente despender, analisando os seus conteúdos, segundo padrões de acessibilidade, pode ser considerável. De forma a mantermos os developers interessados nestes temas, sem que considerem estas verificações cansativas, é importante tornar a sua experiencia tao simples quando possível. é com este objectivo que surgem ferramentas de reparação de acessibilidade. No entanto, se já as avaliações de acessibilidade podem ser algo ambíguas, esta situação agrava-se na reparação. Reparar uma página Web requer um conhecimento relativamente da página bem como uma visão geral que muitas vezes as ferramentas automáticas não possuem. Por este motivo o que propomos neste trabalho são sugestões de reparação, apresentadas ao developer, de forma a que a ferramenta de forneça toda a informação necessária para reparar a acessibilidade dos seus conteúdos. Neste trabalho procedemos ao desenvolvimento de um módulo de reparação para as técnicas CSS desenvolvidas. O objectivo é acima de tudo, mostrar ao developer que pode tornar as suas páginas mais acessíveis, educando-o sobre como o fazer e despoletando o seu interesse explicando também porque o deve fazer. De forma a que toda esta informação possa ser divulgada, é necessário melhorar a interface da ferramenta QualWeb, desenvolvida paralelamente a este projecto. Desenvolveuse paralelamente a este trabalho uma interface para esta ferramenta, no entanto esta interface tem como objectivo apresentar uma versão anterior do QualWeb. De forma a conseguir disponibilizar todos os conteúdos desenvolvidos foi necessário melhorar essa interface introduzindo lhe novas funcionalidades. Todas estas componentes desenvolvidos, foram verificadas através de um corpus de teste. Para a avaliação desenvolvemos testes individuais, por técnica, e globais que simulavam a complexidade de uma páginaWeb real. Para a reparação, procedemos a reparação de algumas das mais utilizadas páginas Web, o que nos permitiu fazer uma analise critica às nossas implementações. Por fim, de forma a validar a interface e as reparações, procedemos a testes com utilizadores. Estes testes foram cruciais para o refinamento da nossa ferramenta, bem como para obtermos algumas conclusões interessantes no nosso trabalho. No final, conseguimos, como pretendíamos, melhorar a ferramenta QualWeb, tornando a ainda mais competitiva nesta área. Conseguimos também validar toda a implementação realizada dos diferentes componentes e tirámos conclusões bastante interessantes. Nomeadamente que o conhecimento de ferramentas deste género, a nível de estudantes de universidade não é muito elevado e que estas ferramentas podem desempenhar um papel interessante para alterar esta situação. Este trabalho ajudou também a pavimentar caminho para novas melhorias desta ferramenta de avaliação de Acessibilidade Web.

Abstract Y-box binding protein-1 (YB-1) is a multi-functional protein involved in several cellular processes including transcription, translation, alternative splicing, virus replication and drug resistance. Since, YB-1 was also found to interact with cisplatin modified-DNA, 8-oxoguanosine and associate with several components of DNA repair system, such as PCNA、DNA polymerse delta and human endonuclease III (hNTH1), YB-1 might involve in DNA repair. However, the precise role of YB-1 in DNA repair is still not fully understood. Here we established YB-1 producing cell line and YB-1 knock-down cell line to determine the role of YB-1 in DNA repair. Using in vivo comet assay, our data indicated that the activity of BER was more activated in YB-1 silencing cells. Consistant with in vivo observation, the in vitro G:U mismatch repair assay also showed the activity of BER was more activated in YB-1 silencing cells. Additionally, the co-localization of PCNA with DNA polymerase delta and YB-1 upon H2O2 treatment was disrupted in YB-1 overexpressing cells treated with H2O2. Moreover, the nuclear localization of hMSH2 upon cisplatin treatment was abrogated in YB-1 overexpressing cells. These results indicate that excess amount of YB-1 may inhibit DNA repair through interfering the proper localization of DNA repair proteins. Together, our finding indicated that YB-1 is a negative regulator of DNA repair system. Deregulated expression of YB-1 in tumor cells may interfere with the behavior of repair machinery, leading to the drug resistance, accumulation of DNA lesions, enhancement of genome instability, and finally cause further progression of tumor cells.

The incomplete-data is the critical problem in the medical environment. In this paper, we provide the data-repairing technique in order to get more information from the primitive data. First, the application exists originally in data in implicit information- relation of the features, and combined expert''s domain knowledge, making it create the features to repair the structure. Using the method that Function Approximation is the application in the foundation of Neural Network to fill block of incomplete-dataset up. And the one of excellent method in the classification - support vector machine, judges examination this research it repairs the mechanism of result. This research evaluates the feasibility that data-repairing mechanism is with two of the category types. The first type is oneself the type of data set that data structure is complete; the purpose is a convenience examination data to repair the result of mechanism. Make by factitiousness that it’s the content of data set and become the data field of having the missing. For simulating the status of missing-data, simulated the mass incomplete-data, medium degree incomplete -data respectively, and a little incomplete-data. There are three kinds of scenarios, hoping can also suit realistic status of the incomplete-dataset. The second type data would be to in concert with the medical data of the collections with the hospital physically, using to be used as the data to be the substantial evidence of data-repairing mechanism. Identification that this research, the incomplete dataset that factitiousness makes repairs the mechanism to fill its blank space of incomplete-data with the data-repairing mechanism. Repair with the incomplete-data later on its data supports the vector machine in order to be used as the classification, the result is obvious. After explaining application this mechanism, have the obvious increment for the right judgment of the data.

A research report submitted In partial fulfilment of the Degree: Master of Commerce University of the Witwatersrand School of Accountancy 2015
This report analyses the use of legitimacy strategies by the platinum mining companies listed on the Johannesburg Stock Exchange (JSE) post the Marikana incident. Content analysis is employed to study the CSR disclosures in the integrated reports of the companies from 2011 to 2013, using pre-determined content themes and integrated report sections. The results provide evidence in support of the legitimacy theory, as the quantity of CSR disclosures mainly focused on social related issues generally increases in the sector during the period under review. Although some companies do not increase their disclosure, their response is still in line with the predictions of legitimacy theory which envisages a change in the reporting pattern, not necessarily always an increase in disclosure. The study also analyses the reports for specific legitimacy strategies in action, and examples of these are provided and scrutinised.

Background and aims: Three are several repairing mechanisms of traumatic tissues. Based on different treatmet targets, the strategies involves in kinds of medication, repairing materials, route of drug and alternative treatments. In different location or categories of injury, patients receive different treatment strategies. As we know, brain-blood barrier in brain injury and extensive injury in skin are with different treatment in tissue healing based on mechanism. To increased brain blood flow is considered on one concept in brain injury. In skin wound, the treatment plan tends to improve the skin healing process. In the present study, brain blood flow model and skin wound healing model are design to investigate the tissue healing process in different organ. Materials and Methods: The first part is to study about increasing cerebral blood flow: We use ATP to activate P2 purinergic receptor to clarify whether activation of NOS resulting in glutamine releasing, which resulting in ATP releasing and increasing common carotid artery blood flow. Microdialysis was used to investigate DFA microinfusion P2 receptor agonists or NO precursor (L-arginine) into the DFA increased CCA blood flow. The second part is about wound healing improved by non-thermal plasma(NTP). Sprague-Dawley(SD) rats was the experimental subjects, and wounds size measuring 2x2 cm were produced on the back . The experimental group was treated with NTP for 5 minutes per day for four weeks. The NTP was injected diffusely into the cage housing the rats. The SD rats not receiving plasma treatment was as control group. Blood was drawn on postoperative days 2 and 4, and at three months. Immunohistochemical (IHC) stain of E-cadherin and 4-hydroxy-2-nonenal (4-HNE), an ROS marker, were evaluated and quantified for analysis by CMYK color model. Sacrificed after 6 month and examine pathological change for skin, lung, liver, kidney. Results: In the first part, We demonstrated that microinjections of P2 receptor agonists (ATP, α,β-methylene ATP) or NO precursor ( L-arginine) into the DFA increased CCA blood flow. The P2-induced CCA blood flow increase was dose-dependently reduced by pretreatment with NG-nitro-arginine methyl ester (L-NAME, a non-specific NOS inhibitor), 7-nitroindazole (7-NI, a relatively selective neuronal NOS inhibitor) or methylene blue (MB, a guanylyl cyclase inhibitor) but not by that with D -NAME (an isomer of L-NAME) or N5-(1-iminoethyl)- L-ornithine (L-NIO, a potent endothelial NOS inhibitor). Involvement of glutamate release in these responses were substantiated by microdialysis studies, in which perfusions of ATP into the DFA increased the glutamate concentration in dialysates, but co-perfusion of ATP with L-NAME or 7-NI did not. Nevertheless, the arginine-induced CCA blood flow increase was abolished by combined pretreatment of L-NAME and MB, but not affected by pretreatment with a selective P2 receptor antagonist, pyridoxalphosphate-6-azophenyl-2 0,4 0-disulphonic acid (PPADS). In the second part, A total of thirty-five SD rats were included in the study (25 in NTP group and 10 in control group). Low dose plasma treatment shortened the wound healing time without damaging organs. In the NTP group, the white blood cell counts at day 2 post-non-thermal plasma treatment was not increased significantly than that in the control group. After quantification of IHC staining , the 4-HNE was increased day 14 compared to day 7 (16.16±12.81% v.s 55.11±8.11% , p<0.001), and E-cadherin was also increased (52.17±14.96% v.s 70.46±12.78 % , p=0.04) in NTP group. Comparison of NTP and control, 4-HNE and E-cadherin were increased in NTP group on day 14. Sacrificed after 6 month and examine skin, lung, liver, kidney, there is no clinical micro- pathological change. Cnclusion: ATP activation of the P2 receptor in the DFA induced activation of neuronal NOS/guanylyl cyclase, which causes glutamate release leading to an increase in CCA blood flow. Short-term, low-dose NTP wound treatment was demonstrated to accelerate the wound healing without vital organ toxicity. These findings provide important information for drug design and/or developing therapeutic strategies.

In this study, two kinds of cement concrete (high performance concrete and steel fiber concrete) and cement pastes (RM-45 and PCM) will be used to investigate the repair efficiency of rigid pavements. In order to evlauate the effect of repair efficiency, specimens with defferent curing ages (3 days, 7 days, 14 days, 28 days and 90 days) were tested on compressive strength, flexural strength and bond strength. Some specimens with specific curing age were tested on water adsorption and changes of shrinkage. According to the traffic jam of our nation, the study will be used the above tests and the failed specimen types to evaluate the efficiency of prospective materials for repair of concrete pavements. This study expects to supply the repairing reference for rigid pavements. 　　The study is divided by the mechanics strength and other physics tests to evaluate the bond efficiency of repairing materials and concrete subbase The experimental data showed that the repairing suface without bonding agent (latex) in bonding concrete can have more high mechanics strength than which with bonding agent. The repairing material could be chosen by the cement pastes (RM-45 and PCM) for shorting the repairing time. The choice of a good bonding agent could be evaluated by the simple test in slant shear and pull-off tests.
