International Telemetering Conference Proceedings / October 20-23, 2003 / Riviera Hotel and Convention Center, Las Vegas, Nevada
One problem facing telemetry engineers is the ability to easily translate telemetry attributes from one system to another. Engineers must develop a written set of attributes that define a given telemetry stream and specify how the telemetry stream is to be transmitted, received, and processed. Telemetry engineers take this document and create the configuration for each product that will be exposed to the telemetry stream (airborne, ground, flight line). This process is time-consuming and prone to error. L-3 Telemetry-West chose to implement a solution using relational databases and eXtensible Markup Language (XML) to solve this and other issues.

Abstract:

In his paper introducing fuzzy sets, L.A. Zadeh describes the difficulty of assigning some real-world objects to a particular class when the notion of class membership is ambiguous. If exact classification is not obvious, most people approximate using intuition and may reach agreement by placing an object in more than one class. Numbers or ‘degrees of membership’ within these classes are used to provide an approximation that supports this intuitive process. This results in a ‘fuzzy set’. This fuzzy set consists any number of ordered pairs to represent both the class and the class’s degree of membership to provide a formal representation that can be used to model this process. Although the fuzzy approach to reasoning and classification makes sense, it does not comply with two of the basic principles of classical logic. These principles are the laws of contradiction and excluded middle. While they play a significant role in logic, it is the violation of these principles that gives fuzzy logic its useful characteristics. The problem of this representation within a database system, however, is that the class and its degree of membership are represented by two separate, but indivisible attributes. Further, this representation may contain any number of such pairs of attributes. While the data for class and membership are maintained in individual attributes, neither of these attributes may exist without the other without sacrificing meaning. And, to maintain a variable number of such pairs within the representation is problematic. C. J. Date suggested a relation valued attribute (RVA) which can not only encapsulate the attributes associated with the fuzzy set and impose constraints on their use, but also provide a relation which may contain any number of such pairs. The goal of this dissertation is to establish a context in which the relational database model can be extended through the implementation of an RVA to support of fuzzy data on an actual system. This goal represents an opportunity to study through application and observation, the use of fuzzy sets to support imprecise and uncertain data using database queries which appropriately adhere to the relational model. The intent is to create a pathway that may extend the support of database applications that need fuzzy logic and/or fuzzy data.

Abstract:

Software effort estimation by analogy is a viable alternative method to other estimation techniques, and in many cases, researchers found it outperformed other estimation methods in terms of accuracy and practitioners' acceptance. However, the overall performance of analogy based estimation depends on two major factors: similarity measure and attribute selection & weighting. Current similarity measures such as nearest neighborhood techniques have been criticized that have some inadequacies related to attributes relevancy, noise and uncertainty in addition to the problem of using categorical attributes. This research focuses on improving the efficiency and flexibility of analogy-based estimation to overcome the abovementioned inadequacies. Particularly, this thesis proposes two new approaches to model and handle uncertainty in similarity measurement method and most importantly to reflect the structure of dataset on similarity measurement using Fuzzy modeling based Fuzzy C-means algorithm. The first proposed approach called Fuzzy Grey Relational Analysis method employs combined techniques of Fuzzy set theory and Grey Relational Analysis to improve local and global similarity measure and tolerate imprecision associated with using different data types (Continuous and Categorical). The second proposed approach presents the use of Fuzzy numbers and its concepts to develop a practical yet efficient approach to support analogy-based systems especially at early phase of software development. Specifically, we propose a new similarity measure and adaptation technique based on Fuzzy numbers. We also propose a new attribute subset selection algorithm and attribute weighting technique based on the hypothesis of analogy-based estimation that assumes projects that are similar in terms of attribute value are also similar in terms of effort values, using row-wise Kendall rank correlation between similarity matrix based project effort values and similarity matrix based project attribute values. A literature review of related software engineering studies revealed that the existing attribute selection techniques (such as brute-force, heuristic algorithms) are restricted to the choice of performance indicators such as (Mean of Magnitude Relative Error and Prediction Performance Indicator) and computationally far more intensive. The proposed algorithms provide sound statistical basis and justification for their procedures. The performance figures of the proposed approaches have been evaluated using real industrial datasets. Results and conclusions from a series of comparative studies with conventional estimation by analogy approach using the available datasets are presented. The studies were also carried out to statistically investigate the significant differences between predictions generated by our approaches and those generated by the most popular techniques such as: conventional analogy estimation, neural network and stepwise regression. The results and conclusions indicate that the two proposed approaches have potential to deliver comparable, if not better, accuracy than the compared techniques. The results also found that Grey Relational Analysis tolerates the uncertainty associated with using different data types. As well as the original contributions within the thesis, a number of directions for further research are presented. Most chapters in this thesis have been disseminated in international journals and highly refereed conference proceedings.

Abstract:

The purpose of this study is to examine and understand social workers view on the relationship between children and social workers within Individual and Family care in Sweden, and how personnel turnover affects relationship-building with children. Method: This study is based on a qualitative method, with semi-structured interviews as an approach to gather empirical data. The participants in the study are seven social workers from five different municipalities in Sweden, who work with placed children. Theory: Our theoretical framework is the attachment theory and the accounts theory. This approach has helped us analyze the result and highlight the importance of essential attributes for a good relationship between social worker and child. Result: The study is characterized by two different themes, Professional relationship-building and The organization of social work. Our results show that the attributes trustful, confiding, straight, predictable and respectful are essential for a good relationship. Further results indicate that continuity is of importance to build and preserve a healthy relationship. The study also shows that variety in the work force have negative impact on the relationship between social workers and placed children.

Abstract:

Possession is an asymmetric semantic relation between two entities, where one entity (the possessee) belongs to the other entity (the possessor). Automatically extracting possessions are useful in identifying skills, recommender systems and in natural language understanding. Possessions can be found in different communication modalities including text, images, videos, and audios. In this dissertation, I elaborate on the techniques I used to extract possessions. I begin with extracting possessions at the sentence level including the type and temporal anchors. Then, I extract the duration of possession and co-possessions (if multiple possessors possess the same entity). Next, I extract possessions from an entire Wikipedia article capturing the change of possessors over time. I extract possessions from social media including both text and images. Finally, I also present dense annotations generating possession timelines. I present separate datasets, detailed corpus analysis, and machine learning models for each task described above.

This study aimed to explore in a deductive way the relationship between constructs: STI biotechnology, considered at the regional level, the relational capabilities of human biotechnology companies, and the attributes of the transaction costs of alliances in Brazil. The universe considered were companies operating in the biotechnology industry. The sample was composed of companies active in human health biotechnology industry in the states of São Paulo, Minas Gerais, Rio de Janeiro, Paraná and Rio Grande do Sul. The levels of analysis were the constructs: Technological Innovation System, Attributes of Cost Transaction and Capacity Relational. The unit of analysis was the contractual strategic alliances formalized by the companies. A structural sample was developed and measurement consists of causal relationships based on existing theory. From the sample, latent variables were defined at first, second and third order and measurable indicators. Data were collected in two ways: access to secondary data, provided by the government and private organizations, access to primary data through structured interviews with managers or people directly connected with the management of strategic alliances contractual process. To test the measurement model, it was conducted to the analysis of structural equation modeling method solved by Partial Least Squares. The results show that the dynamics of Technological Innovation System influences the frequency of transactions, but it proved not to be enough to change the nature of the uncertainty of transactions, as well as in relation to the Assets Specificity. The Technological Innovation System also positively influenced but not statistically significant the Relational Capacity, demonstrating not to be, by itself, capable of generating development of this type of dynamic capability. The ratio of positive influence of Attributes Transaction Cost in the development of relational capacity was confirmed. The moderation hypothesis was confirmed, making it possible to say that allowing the Technological Innovation System strengthens the relationship between the attributes of the Transaction Cost and Relational Capacity. The paper finally presents theoretical and methodological contributions arising from analysis of the relationships discussed practical contributions to managers of companies operating in the industry and for the formulation of public policies whose goal is regional and economic development of the biotechnology industry, human health in Brazil.
Esse estudo teve como objetivo explorar de forma dedutiva a relação entre os construtos: STI de biotecnologia, considerado no nível regional; a capacidade relacional das empresas de biotecnologia humana; e os atributos dos custos de transações de alianças no Brasil. O universo considerado foram as empresas que atuam na indústria de biotecnologia. A amostra foi composta pelas empresas atuantes na indústria de biotecnologia saúde humana, nos estados de São Paulo, Minas Gerais, Rio de Janeiro, Paraná e Rio Grande do Sul. Os níveis de análise foram os construtos: Sistema Tecnológico de Inovação, Atributos dos Custos de Transação e Capacidade Relacional. A unidade de análise foram as alianças estratégicas contratuais formalizadas pelas empresas. Foi elaborado um modelo estrutural e de mensuração composto por relações causais baseadas na teoria existente. A partir do modelo, definiram-se variáveis latentes de primeira, segunda e terceira ordem e indicadores mensuráveis. Os dados foram coletados de duas formas: acesso a dados secundários, disponibilizados por organizações governamentais e privadas; acesso aos dados primários por meio de entrevistas estruturadas realizadas com gestores ou pessoas diretamente ligadas ao processo de gestão das alianças estratégicas contratuais. Para testar o modelo de mensuração procedeu-se à análise da modelagem de equações estruturais resolvido pelo método Partial Least Squares. Os resultados mostram que a dinamicidade do Sistema Tecnológico de Inovação exerce influência na Frequência das transações, mas demonstrou não ser suficiente para alterar a natureza da Incerteza das transações, bem como em relação à Especificidade dos Ativos. O Sistema Tecnológico de Inovação ainda influenciou de forma positiva, mas não estatisticamente significativa a Capacidade Relacional, demonstrando não ser, por si só, capaz de gerar desenvolvimento desse tipo de capacidade dinâmica. Foi confirmada a relação de influência positiva dos Atributos do Custo de Transação no desenvolvimento da Capacidade Relacional. Quanto à hipótese de moderação, foi confirmada, possibilitando dizer que o Sistema Tecnológico de Inovação reforça a relação entre os Atributos do Custo de Transação e a Capacidade Relacional. O trabalho, por fim apresenta contribuições teóricas e metodológicas advindas das análises das relações discutidas, contribuições práticas para os gestores das empresas que atuam na indústria e para a formulação de políticas públicas cuja meta seja o desenvolvimento regional e econômico da indústria de biotecnologia, saúde humana, no Brasil.

Abstract:

To combat fake news, researchers mostly focused on detecting fake news and journalists built and maintained fact-checking sites (e.g., Snopes.com and Politifact.com). However, fake news dissemination has been greatly promoted by social media sites, and these fact-checking sites have not been fully utilized. To overcome these problems and complement existing methods against fake news, in this thesis, we propose a deep-learning based fact-checking URL recommender system to mitigate impact of fake news in social media sites such as Twitter and Facebook. In particular, our proposed framework consists of a multi-relational attentive module and a heterogeneous graph attention network to learn complex/semantic relationship between user-URL pairs, user-user pairs, and URL-URL pairs. Extensive experiments on a real-world dataset show that our proposed framework outperforms seven state-of-the-art recommendation models, achieving at least 3~5.3% improvement.

Abstract:

Data analysts today have at their disposal a seemingly endless supply of data and repositories hence, datasets from which to draw. New datasets become available daily thus making the choice of which dataset to use difficult. Furthermore, traditional data analysis has been conducted using structured data repositories such as relational database management systems (RDBMS). These systems, by their nature and design, prohibit duplication for indexed collections forcing analysts to choose one value for each of the available attributes for an item in the collection. Often analysts discover two or more datasets with information about the same entity. When combining this data and transforming it into a form that is usable in an RDBMS, analysts are forced to deconflict the collisions and choose a single value for each duplicated attribute containing differing values. This deconfliction is the source of a considerable amount of guesswork and speculation on the part of the analyst in the absence of professional intuition. One must consider what is lost by discarding those alternative values. Are there relationships between the conflicting datasets that have meaning? Is each dataset presenting a different and valid view of the entity or are the alternate values erroneous? If so, which values are erroneous? Is there a historical significance of the variances? The analysis of modern datasets requires the use of specialized algorithms and storage and retrieval mechanisms to identify, deconflict, and assimilate variances of attributes for each entity encountered. These variances, or versions of attribute values, contribute meaning to the evolution and analysis of the entity and its relationship to other entities. A new, distinct storage and retrieval mechanism will enable analysts to efficiently store, analyze, and retrieve the attribute versions without unnecessary complexity or additional alterations of the original or derived dataset schemas. This paper presents technologies and innovations that assist data analysts in discovering meaning within their data and preserving all of the original data for every entity in the RDBMS.

Abstract:

Attributed Relational Graph (ARG) is a powerful representation for model based object recognition due to its inherent robustness in handling noisy and incomplete data. In the past few years, the availability of efficient ARG matching algorithms and their theoretical underpinnings have greatly contributed to many successful applications of ARG representation in tackling high level vision problems. During my past three year investigation into object recognition using ARG representation, we have developed a number of novel theories and techniques in the subject area. Some are image processing techniques which help to segment and generate primitive features for building ARG representation (Chapter 2 and 4). Some are about projective invariance in ARG representations (Chapter 3 and 5). Some are about new ARG matching algorithms (Chapter 6). This thesis serves as a summary document of these theories and techniques. The most important contributions of our work to the domain of computer vision, in my opinion, are in two areas: Firstly, in the area of projective invariant ARG representation for object recognition. Here, we demonstrated for the first time, a way to systematically derive ARG representation for objects under complex projective transform by exploiting the knowledge of invariance. The methodology developed by us is a sound strategy that generates ARG representations with a number of desirable and provable properties, amongst which, the most important one is the ability to capture global transformation constraint using binary relations only. The approach significantly reduces the heuristic nature of designing relational measurements and paves the way for wider application of ARG representation in 2D and 3D object recognition. Secondly, in the area of ARG matching. A new mathematical framework for deterministic relaxation algorithms was developed to overcome a number of problems appeared in the existing theories and practises of efficient ARG labelling. A novel labelling algorithm was proposed based on the new theoretical framework. The algorithm has a number of desirable properties compared to existing algorithms. In particular, the resulting algorithm delivers more consistent, faithful-to-observation results in the presence of ambiguities and multiple interpretations compared to other algorithms.

Abstract:

The interest in designing interactive systems is going beyond their functionality and more towards their aesthetics. Often, research fails to address how qualities of the interaction as a medium can actually create pleasurable experiences. However, it points out the importance of understanding temporal aspects of interactions to understand their aesthetics. The aim for this thesis is to address this by the creation and evaluation of an interactive artwork working as a platform to explore relations between Interaction attributes and Pleasures, as well as how temporal aspects in interactions can affect these Pleasures. This to help interaction designers think more clearly around and make better design choices regarding interactions within interactive systems. The results of this showed that there can be many such relations, but also that they are complex. Additionally, it is discussed that Pleasures might also partly be experienced before or after the interaction with the artwork.

Abstract:

Most data mining and pattern recognition techniques are designed for learning from at data files with the assumption of equal populations per class. However, most real-world data are stored as rich relational databases that generally have imbalanced class distribution. For such domains, a rich relational technique is required to accurately model the different objects and relationships in the domain, which can not be easily represented as a set of simple attributes, and at the same time handle the imbalanced class problem.Motivated by the significance of mining imbalanced relational databases that represent the majority of real-world data, learning techniques for mining imbalanced relational domains are investigated. In this thesis, the employment of probabilistic models in mining relational databases is explored. In particular, the Probabilistic Relational Models (PRMs) that were proposed as an extension of the attribute-based Bayesian Networks. The effectiveness of PRMs in mining real-world databases was explored by learning PRMs from a real-world university relational database. A visual data mining tool is also proposed to aid the interpretation of the outcomes of the PRM learned models.Despite the effectiveness of PRMs in relational learning, the performance of PRMs as predictive models is significantly hindered by the imbalanced class problem. This is due to the fact that PRMs share the assumption common to other learning techniques of relatively balanced class distributions in the training data. Therefore, this thesis proposes a number of models utilizing the effectiveness of PRMs in relational learning and extending it for mining imbalanced relational domains.The first model introduced in this thesis examines the problem of mining imbalanced relational domains for a single two-class attribute. The model is proposed by enriching the PRM learning with the ensemble learning technique. The premise behind this model is that an ensemble of models would attain better performance than a single model, as misclassification committed by one of the models can be often correctly classified by others.Based on this approach, another model is introduced to address the problem of mining multiple imbalanced attributes, in which it is important to predict several attributes rather than a single one. In this model, the ensemble bagging sampling approach is exploited to attain a single model for mining several attributes. Finally, the thesis outlines the problem of imbalanced multi-class classification and introduces a generalized framework to handle this problem for both relational and non-relational domains.

Abstract:

It is next to impossible to let a day go by without coming into contact with a computer system in some way, either by direct usage, or making a telephone call that is directed by computer systems. Due to the importance of computer systems we are all concerned with their quality, directly or indirectly, a malfunctioning system will disturb our lives in more or less drastic ways. Each stakeholder promotes his qualities and priorities for the system, and this will eventually lead to conflict, depending on relations between qualities. There is no simple solution to the problem of relating and conflicting quality attributes. But by making an informed decision it is possible to soften the effects of the trade-offs and gain a higher level of total software quality. The way to make an informed decision is to have knowledge about the relations between quality attributes along with insights of the consequences of the decision. This report gives a short introduction to the problem, and surveys both the relations stated within academia, and industry. The intention is to explore the knowledge present within academia and collect and present the established relations found by researchers. Further this report presents a survey carried out at companies working in different areas with software engineering, to show which relations that are visible to industry and how they are handling the relations between quality attributes. This gathered knowledge intends to support the ambition towards higher quality in software engineering.

Full text

Abstract:

Solid surfaces that spend long periods of time in aquatic environments are susceptible to the accumulation of marine fouling organisms and this phenomenon is known as marine biofouling. This is a natural process which has significant impacts on marine industries. Research to develop new antifouling solutions focuses on the development of non-toxic solutions that can deter biofouling. A non-toxic antifouling approach that has gained interest in recent years is to modify the surface’s structure to disrupt organism settlement (Kirschner and Brennan 2012; Magin et al. 2010; Myan et al. 2013). Many studies determined that uniform arrays of single layered, micro-topographies are effective at deterring the initial settlement of fouling organisms. In contrast, most studies that tested uniform arrays of single layered, macro-topographies concluded that these topographies are not suitable for antifouling applications. Both single layered, micro-topographies and single layered, macro-topographies were determined to have limitations at mitigating biofouling. This resulted in the interest to develop hierarchical topographies. Hierarchical topographies are surfaces that consist of features that are varied in size and shape. It was suggested that the diverse nature of hierarchical topographies might be able to deter biofouling from a wider array of organisms. This research fabricated and tested a wide range of topographies (uniform, non-uniform, micro, macro, hierarchical, etc.) in a field study. A field study was preferred over lab experiments because results will reflect the antifouling efficacy of the surfaces in a marine environment. These results will indicate the topographies’ viability and future potential for industrial applications. Antifouling efficiency was evaluated by measuring fouling resistance (during the field test) and fouling removal (after the field test) of all topographies. Physical attributes (pattern geometry, pattern size, and surface roughness) of topographies were characterised with Scanning Electron Microscopy (SEM) and Laser Scanning Confocal Microscopy (LSCM). Statistical analysis was carried out to evaluate the significance of the topographies’ physical attributes on the antifouling efficiency of the topographies. The research hypotheses predicted that topography size, geometry and surface roughness will affect the topographies’ ability to resist biofouling. All patterned surfaces were predicted to have a higher resistance to biofouling in comparison to un-patterned control surfaces (i.e. smooth surfaces). The possibility that hierarchical topographies would have better fouling resistance properties than micro-topographies was considered as well. Hierarchical topographies and micro-topographies were also hypothesised to demonstrate better resistance to biofouling than macro-topographies. Topographies with straight ridges and hierarchical shapes were predicted to be more fouling resistant than sandpaper surfaces. Topographies with average roughness (RSa) that were less than 100µm were assumed to exhibit better antifouling efficacy in comparison to topographies with average roughness greater than 100µm. Results showed that pattern size and pattern geometry affects the antifouling efficiency of topographies. Unexpectedly, surface roughness did not show strong correlations with the fouling resistance of the topographies. With the exception of Sandpaper 50 and Sandpaper 1mm samples, all topographies were more fouling resistant than the control samples (i.e. smooth surfaces). Among the 16 topographies, sandpaper 1mm samples demonstrated the worst defence against biofouling. The mean total fouling coverage on these samples after 10 weeks of tests was 98.7%. Straight, single layer ridges demonstrated the best resistance to total fouling during the field test. Barnacle and polychaete settlement trends were affected by the size and geometry of single layer, single sized topographies. After 10 weeks, the mean total fouling coverage on these ridges was only 37.5%. The field test also showed that the topography with the best prolonged resistance to fouling was the 1mm straight ridges. The combination of structured surfaces and a low modulus material is likely to have contributed to the fouling removal properties of all topographies. Lastly, results from the field study also showed that hierarchical topographies do not necessarily have better antifouling properties than single layer, single sized topographies. The field study demonstrated that the physical attributes of topographies contributed to their antifouling efficiency. It has been suggested that the physical characteristics of topographies induces hydrodynamic variations that affects the surfaces’ antifouling properties. However, it is difficult to observe these changes in lab experiments or through field studies because these variations take place at a very small scale. Recent research has applied Computational Fluid Dynamics (CFD) to numerically simulate and analyse flow characteristics in the surrounding areas of antifouling topographies. As a continuation from the field study, the next study in this research applied CFD to analyse flow characteristics over several topographies that were tested in the field study. This was to determine if the settlement trends exhibited by organisms in the field study could have been affected by hydrodynamic variations that were induced by the presence of the topographies. The CFD analysis showed that rotational vortices formed between topography patterns. These vortices could have aided in the accumulation of biofouling material on all topographies during the field test. The analysis also showed that the topographies’ resistance to fouling could be attributed to high shear stress and strain rate zones at the peaks of the topographies. Comparisons between CFD and field test results indicate that higher stresses and strain rate zones around the topographies are likely to lead to a surface’s better resistance to marine biofouling. This is likely because high shear stress and strain rate zones could have disrupted organism motility and made the surface less conducive for settlement.

Abstract:

“Live” (stained) and dead macrofaunal (>300 μm fraction) foraminifera in multicorer samples (0-1 cm and 0-5 cm layers) were analysed at six stations along a transect (100-3400 m water depth) across the Oman margin (Arabian Sea) oxygen minimum zone (OMZ). Very high abundances (2858 per 25.5 cm2), dominated by Uvigerina ex. gr. semiornata, were found in the upper 100 m. The 850 m site also had elevated abundances. These peaks probably represented upper and lower OMZ boundary edge effects, respectively. A total of 199 live species was recognized. Diversity was depressed between 100 m and 850 m and relatively higher at the 1250 m and 3400 m sites. Vertical distribution in the sediment reflected responses found across the horizontal gradient, with species concentrated in the top sediment where bottom-water oxygen concentration was low and distributed more evenly through the sediment where concentration was higher. In general foraminifera and metazoan responded similarly to oxygen and food availability, except that the lower boundary of edge effect was located at a shallower depth (700 m) for the metazoans. Live:dead ratios of foraminifera increased with water depth. The second part of the thesis concerns Gromia, a large marine protist with filose pseudopodia and an organic test that is abundant in the bathyal Arabian Sea. Deep-water Gromia-like morphospecies were discovered in the 1990’s but their relation to shallow-water species was not established. Little is known about gromiid diversity, reflecting the fact that these relatively featureless protists have few characters useful for species identification. Consequently, ultrastructural and molecular techniques were used to examine gromiid diversity on the Oman and Pakistan margins of the Arabian Sea (water depths 1000-2000 m). In total, 27 deep-sea gromiid sequences of the SSU rDNA gene and 6 sequences of the ITS rDNA region were obtained. The data confirmed that Gromia-like protists from the bathyal deep sea are related to shallow-water gromiids. Among Arabian Sea Gromia, seven lineages were identified based on molecular evidence. Five of them form a monophyletic group branching as a sister group to shallow-water species. Four lineages can be defined morphologically, while grape-like morphotypes include 3 lineages that cannot be distinguished morphologically. Each lineage probably represents a separate species, implying that deep-sea gromiid diversity is higher than indicated by their simple morphology. Morphological analysis adds 2 more species, giving a total of 9 deep-sea gromiid species, adding considerably to the number of known marine gromiids, only three of which are currently described.

Abstract:

This study investigated the importance that junior and senior job-seeking undergraduates (Millennial generation members) place on transactional and relational work attributes; how ratings vary by gender, experiences with layoff, and intended loyalty; and how well ratings match with actual attributes offered by organizations. Results are discussed in context of psychological contract theory. Students (n = 199) and recent graduates working full-time (n = 180) took separate online survey. Students indicated the importance of various work attributes (Ng, Schweitzer, & Lyons, 2010), loyalty intentions, and other related questions. Graduates answered only work attribute questions related to their current employer. Work attributes were factored into new transactional (IMP-T; µ = .78) and relational scales (IMP-R; µ = .91). Key results indicated that students rated relational work attributes more highly than transactional attributes (p < .001); gender had no effect on importance ratings or intended loyalty; and students’ importance ratings were above the workplace reality.

Abstract: The production of the main soil greenhouse gases (GHG: CO2, CH4 and N2O) is influenced by agricultural practices that causes changes in soil phys¬ical, chemical and biological attributes, directly affecting their emission to the atmos¬phere. The aim of this study was to investigate the infield soil CO2 emissions (FCO2) and the soil CO2, CH4 and N2O production potentials (PCO2, PCH4 and PN2O, respec¬tively) in laboratory conditions, and their relationship to soil attributes in a mechanically harvested sugarcane area. The experimental area consisted of a 50 × 50-m radially symmetrical grid containing 133 points spaced at minimum distances of 0.5 m in the center of the sample grid. It was carried out eight evaluations of FCO2, soil temperature and soil moisture over a period of 19 days. Soil physical and chemical attributes were determined by sampling at a depth of 0-10 cm. The quantification of PCO2, PCH4 and PN2O consisted of laboratory incubation and determination of gas concentration by gas chromatography. FCO2 presented an infield average emission value of 1.19 µmol CO2 m−2 s−1, while GHG production in laboratory was 2.34 µg C-CO2 g−1 d−1 and 0.20 ng N-N2O g−1 d−1 for PCO2 and PN2O, respectively. No significant production or oxidation was observed for CH4. The factor analysis showed the formation of two independent processes that explained almost 72% of the total variance observed in the data.

Abstract:

The aim of this thesis is to study how words denoting age are used in newspaper texts. I have chosen mainly to study the following Swedish focus words for females and males of different ages (flicka, kvinna, tjej, dam; pojke, man, kille and herre) as they relate to age. Furthermore, age lexemes – different variations of Swedish expressions of age – are investigated and finally also a number of new Swedish expressions that are used to describe age – kids, förtis, grups, tweenie, mappie, senior and what I call “plus gradings” – e.g. 50 +.

The study is particularly concerned with where and how age is referred to and how the chosen focus words relate in different ways to age and sex – and finally also with how these things have changed over time. I have examined newspaper corpora from three separate years – 1965, 1987 and 2000. My theoretical perspective is social constructivist, age being understood as something that is constructed and negotiated in language use. As for method, I adopt a corpus linguistic approach – large corpora and quantitative language patterns in frequencies and lexical content. Thus, my investigation is aimed at the focus words, the age lexemes and the terms in their linguistic contexts, primarily as regards adjective attributes, lexical relations and collocations.

My conclusion is that the examined expressions occur in different contexts and are used in different ways, but are not always related to age or age differentiation. I have noticed a couple of tendencies; one relates to vagueness when it comes to age and one relates to a semantic division of labour. The focus words are both used as synonyms and as oppositions, and they refer to referents belonging to different age groups. At the same time there is a clear division of labour between them in that variation in many contexts relates more to subject and contextual pattern than to different chronological ages. Ihave also noticed that chronological age is generally used when something is unusual, deviant or when the context has to do with crime, sports, (change of or debut in) a profession, birthday announcements etc.

Den här avhandlingen undersöker hur ålder används språkligt i tidningstext. Utgångspunkten är hur ålder har förändrats. Framförallt är det fokusorden flicka, pojke, man, kvinna, kille, tjej, dam och herre som i relation till ålder undersöks i avhandlingen. Därutöver studeras ålderslexem - olika variationer av de språkliga uttrycken ålder och år och slutligen även ett antal nya begrepp som förekommer i relation till ålder – kids, förtis, grups, tweenie, mappie, senior och det jag kallar för plusgraderingar – t ex 50 +.

Frågor jag ställer mig har med var och hur ålder förekommer och hur de utvalda fokusorden relateras på olika sätt till ålder och till kön – och slutligen hur detta har förändrats över tid. Jag har studerat tidningskorpusar från tre olika årtal – 1965, 1987 och 2000. Teoretiskt utgår jag från ett socialkonstruktivistiskt perspektiv där ålder ses som någonting som konstrueras och förhandlas i språkanvändningen. Metodologiskt utgår jag från ett korpuslingvistiskt synsätt - stora textkorpusar och kvantitativa språkliga mönster i frekvenser och lexikalt innehåll. Jag studerar alltså fokusorden, ålderslexemen och de nya begreppen i sina språkliga kontexter, och då framförallt adjektivattribut, lexikala relationer och kollokationer.

Jag kommer fram till att de olika språkliga uttrycken förekommer i olika typer av kontexter och på olika sätt, men att det långt ifrån alltid har med ålder eller med åldersdifferentiering att göra. Två olika tendenser är tydliga som har med åldersvaghet och arbetsfördelning att göra. De olika fokusorden både likställs och differentieras, och de används om referenter i olika ålderskategorier. Samtidigt är det en tydlig arbetsfördelning mellan dem där variationen i många sammanhang har mer med ämnen och innehållsliga mönster att göra, än med olika kronologiska åldrar. Jag har också kunnat konstatera att kronologisk ålder generellt används när någonting är ovanligt eller avvikande utifrån en åldersnorm eller när kontexterna har med idrott, debut eller byte av profession, födelse- och dödsannonser etc.

Abstract:

Three studies examined the relation of intimacy motivation as a social motive to interpersonal functioning. In Study 1, a self-report measure of intimacy motivation (san Int) was first constructed and then compared to the existing thematic measure (n Int; McAdams, 1992). The two motive measures were uncorrelated and associated with different quantitative and qualitative dimensions of social interactions. Nonetheless, both were independent predictors of the valence of interpersonal interaction. In Study 2, n Int and san Int were again found to be uncorrelated and to independently predict the valence of social interactions. In addition, the results indicated that although n Int and san Int were somewhat differently related to the sources and form of social support, both contributed independently as well as interactively to the perception of social support. In Study 3, the two forms of intimacy motivation were considered along with interpersonal skill and values in the prediction of rapport in a specific close relationship. The results showed that n Int and san Int independently predicted dyadic rapport as well as interacted with levels of interpersonal skill and values. Interestingly, there was also a negative interaction between n Int and san Int. Taken together, this series of studies provides strong support for distinguishing between motives assessed via self-report and thematic analysis as tapping two qualitatively different kinds of motivation. In addition these studies clearly indicate that the best prediction of interpersonal functioning is accomplished through the assessment of both kinds of motivation along with measures of interpersonal skills and values.

Abstract:

The purpose of this exploratory study was to compare various attributes of never-married single men and women to married men and women. The Taylor-Johnson Temperament Analysis, the Fundamental Interpersonal Relations Orientation-Behavior (FIRO-B) Scale, and the Personal Skills Map were completed by 138 never-married singles and 139 married volunteers, both male and female. Volunteers were predominantly Caucasian, Protestant, active in their churches, and college educated. Ages ranged from 30 to 39 years. Married volunteers were married only once for five years or more. A step-wise discriminant analysis was run on each of the three instruments to determine which variables were significant across groupings. Summary conclusions were made showing that never-married men and women were more socially energetic but less expressive and responsive than were married men and women. Single men, as compared to married men, were also more passive and saw themselves in a less favorable light. Single women, when compared to married women, were also more dominant. Single women, when compared to single men, were more relaxed and more assertive, but more critical and punitive. An implication for counselors is that never-married single people may need help with relating at a deeper level of vulnerability and personableness. Single men may need help in interpersonal assertiveness as well as in personal openness and transparency. Single women may need help in resolving some of their hostilities. Further research is needed to explore the possible factors contributing to the guardedness of singles, the passivity of men, and the hostility of women. More work needs to be done in the area of causality.

Abstract:

This study represented an initial effort to systematically examine the effects of the perception of servant-leadership attributes in union leaders on the commitment and participation levels of union members. Using Barbuto and Wheeler's (2006) Servant Leadership Questionnaire, and Gordon, Philpot, Burt, Thompson and Spiller's (1980) Commitment to the Union Scale, 535 members of a U.S.-based, national healthcare union rated their union leaders on servant-leadership attributes, and answered a series of questions designed to assess their level of union commitment. Additionally, demographic and participation information was collected. A combination of descriptive statistics, and Baron and Kenny's (1986) mediation methodology was used to determine the relationship between servant-leadership attributes, union commitment attributes, and an overall participation score. Demographic information was used to determine generalizability. The results of this study indicate that each attribute of servant-leadership showed a relationship with overall union member participation and with each attribute of union commitment. The only instance in which an attribute of union commitment consistently mediated the relationship between servant-leadership and overall union member participation was union loyalty. While the respondents in this study reported lower scores on those attributes of servant-leadership and union commitment that emphasize the personal over the collective, this does not negate the statistical significance of the impact on servant-leadership on union commitment. The results of this study confirms that, in the case of the sponsoring organization, servant-leadership is a viable leadership paradigm with the potential to increase both commitment to the union-as-organization, as well as increasing overall union member participation.

Abstract:

Notre société est marquée par le développement toujours plus performant des techniques médicales. Paradoxalement, alors que la médecine se spécialise et se complexifie, le grand public ressent de plus en plus le besoin de comprendre. Le droit a du suivre cette progression scientifique. L'information fait donc désormais partie intégrante de la relation entre le professionnel de la santé et le patient et plus précisément entre ce dernier et le médecin au point de constituer un véritable attribut de la personne. Pour cela, il pèse sur le médecin, dans le cadre de son activité aussi bien libérale qu'hospitalière, une obligation de renseignement destinée à éclairer le malade sur son état de santé, sur les procédures diagnostics, sur les modalités thérapeutiques envisageables, à lui fournir l'ensemble des éléments lui permettant de prendre des décisions en connaissance de cause, notamment d'accepter ou de refuser les actes proposés. L'information considérée longtemps comme secondaire constitue dorénavant le corollaire indispensable à l'assentiment. .
Our society is influenced by the increasing development of medical techniques. Paradoxically, while medicine is specializing and becoming complexe, people feel more and more the need to understand. Low had to follow this scientific progress. Information therefore becomes an integral part of the health professional and the patient relation and more precisely between the patient and the doctor until becoming a true attribute of the person. To achieve this, the doctor is now confronted, in private as well as in public medicine to an informative obligation meant to enlighten the patient on his health status, diagnostics proceedings, possible therapy conditions, to provide him with the elements allowing him to take deeply thought decisions, accepting or refusing treatments proposed. Information though long considered as secondary is now essentialy complementing consent. .

Abstract:

We are living in a world full of uncertainty and ambiguity. We usually ask ourselves questions that we are uncertain about their answers. Is it going to rain tomorrow? What will be the exchange rate of euro next month? Why, where and how should I invest? Type-1 Fuzzy sets are characterized by the membership function whose value for a given element x is said to be the grade of membership having a value in the interval [0, 1]. In addition, type-1 fuzzy sets have limited capabilities to deal with uncertainty. In our thesis, we study another concept of a fuzzy description of uncertainty which is called Type-2 fuzzy sets. According to this concept, for any given element x, we can’t speak of an unambiguously specified value of the membership function. Moreover, Type-2 fuzzy sets constitute a powerful tool for handling uncertainty. The aim of our thesis is to examine the potential of the Type-2 fuzzy sets especially in decision making. So, we present basic definitions concerning Type-2 fuzzy sets, and operations on these sets are to be discussed too. Then, Type-2 fuzzy relations and methods of transformation of Type-2 fuzzy sets will be introduced. Also, the theory of Type-2 Fuzzy sets will serve for the construction of the fuzzy inference system. Finally, we utilize interval type-2 fuzzy sets in the application of Multiple Attributes Group Decision Making which is called TOPSIS.

Abstract:

The Ancient Egyptians have always had a strong connection with their animals. This can be seen in the depictions of their gods as well as in their way of writing in hieroglyphics, in which multiple animal figures are used. The Ancient Egyptians are also associated strongly with the afterlife and their interest in the deceased and funerary texts. Much of the Ancient Egyptian material culture that has been preserved has some connection to one of these aspects. Their funerary culture has been well-preserved thanks to the dry and arid conditions of the desert, while the Nile has almost completely destroyed the rest of their culture. This dissertation focuses on the relationship of the Ancient Egyptians with animals, specifically canines, in association with death and the afterlife. The focus is on the similarities between canines and the main canine deities: Anubis, Wepwawet, and Duamutef, listing the connections between the funerary, canine gods and the animals the Egyptians linked to them. It also looks at the hieroglyphic representation of both the gods and the canines. The animals in question are also briefly discussed, analysing their behaviour, and linking it to the information gathered on the canine deities.

Abstract:

Over the past thirty years, clinical research has benefited substantially from the adoption of electronic medical record systems. As deployment has increased, so too has the number of researchers seeking to improve the overall analytical environment by way of tools and models. Although much work has been done, there are still many uninvestigated areas; two of which are explored in this dissertation. The first pertains to the physical storage of the data itself. There are two generally accepted storage models: relational and entity-attribute-value (EAV). For clinical data, EAV systems are preferred due to their natural way of managing many-to-many relationships, sparse attributes, and dynamic processes along with minimal conversion effort and reduction in federation complexities. However, the relational database management systems on which they are implemented, are not intended to organize and retrieve data in this format; eroding their performance gains. To combat this effect, we present the foundation for an EAV Database Management System (EDBMS). We discuss data conversion methodologies, formulate the requisite metadata and partitioned type-sensing index structures, and provide detailed runtime and experimental analysis with five extant methods. Our results show that the prototype, EAVDB, reduces space and conversion requirements while enhancing overall query performance. The second topic concerns query performance in a federated environment. One method used to decrease query execution time, is to pre-compute and store "beneficial" queries (views). The View Selection Problem (VSP) identifies these views subject to resource constraints. A federated model, however, has yet to be developed. In this dissertation, we submit three advances in view materialization. First, a more robust optimization function, the Minimum-Maintenance View Selection Problem (MMVSP), is derived by combining existing approaches. Second, the Federated View Selection Problem (FVSP), built upon the MMVSP, and federated data cube lattice are formalized. The FVSP allows for multiple querying nodes, partial and full materialization, and data propagation constriction. The latter two are shown to greatly reduce the overall number of valid solutions within the solution space and thus a novel, multi-tiered approach is given. Lastly, EAV materialization, which is introduced in this dissertation, is incorporated into an expanded, multi-modal variant of the FVSP. As models and heuristics for both the federated and EAV VSP, to the best of our knowledge, do not exist, this research defines two new branches of data warehouse optimization. Coupled with our EDBMS design, this dissertation confronts two main challenges associated with clinical data warehousing and federation.

Full text

Abstract:

A paradigm shift from mass marketing to the concentrated focus on one-to-one marketing has led to a barrage of tactical strategies to instill long-tern consumer loyalty among organisations' most valued customers. At the forefronts of these strategies are customer loyalty programs. Since the inception of the first loyalty program, AAdvantage in 1981, the marketplace has seen a proliferation of these programs across a widening range of industries. Not surprisingly, this has led to significant interest in customer loyalty programs among academics and practitioners. Despite the skepticism of academics relating to the effects of loyalty programs, many organisations have allocated a large amount of the or marketing budgets to developing, implementing and maintaining customer loyalty programs in the hope of generating long-term loyalty in customers. To date, current evaluations of customer loyalty programs have assessed the effects of these programs by focussing on behavioural measures (such as repeat purchases) and on economic outcomes (such as market share, penetration and share of wallet.) While these traditional measures have contributed to the understanding of consumer loyalty and evaluations of a program’s success, it has been recognised by researchers that the measures are inadequate to determine and explain the loyalty-building attributes of loyalty programs. Moreover, studies from the viewpoint of consumers remain lacking. In an attempt to bridge the gap, this qualitative study explores the attributes of customer loyalty programs that result in consumer loyalty to brands from the perspective of the consumer. The fundamental significance of this study is the integration of the behavioural and the attitudinal theoretical approaches used to investigate these attributes. In addition to this integrative approach, the study incorporates theories from relationship marketing. The components of loyalty and attributes of loyalty programs that were investigated were drawn from an extensive review of the brand loyalty, relationship marketing and customer loyalty program literatures. These components and attributes were deemed to be the most significant in establishing long-term consumer loyalty. The data for this qualitative study were derived from twenty-four semi-structured focused interviews with consumers who qualified as members of customer loyalty programs. The tentative conclusions drawn from this research are that from consumer’s points of view: (i) the act of loyalty is exhibited by the continual repeat purchase of the same product from the same store, (ii) the key to a successful customer loyalty program is the implementation of a program that is flexible to its members, (iii) the key to a defensive orientated loyalty program is a good incentive structure and an effective communication program, and (iv) the development and sustenance of a relationship between a consumer and an organisation is vital to the brand loyalty process. The results of this exploratory study provide a deeper understanding of the customer loyalty program phenomenon and the identification of program attributes that result in long-term consumer loyalty from the perspective of consumers. This research highlights that further investigation is required into the loyalty-building attributes of customer loyalty programs, and this will be central to the development of loyalty programs that satisfy consumers and effectively establish long-term loyalty to brands.

Abstract:

Les prestations de conseils se développent de façon ininterrompue depuis plusieurs décennies et la relation client-consultant apparait selon les travaux en sciences de gestion comme un facteur explicatif essentiel de leur performance. Cette revue de littérature montre que le thème du conseil reste peu développé, notamment en France, et qu’il nécessite un large développement dans les années à venir, notamment avec le changement des environnements et pratiques professionnels. Également, la plupart des travaux s’intéressent à la figure du consultant et assez peu à la relation de conseil. Ainsi nos travaux ont pour objet de contribuer à une meilleure compréhension de ce qu’elle est et de sa dynamique.Nous proposons dans cette contribution d’utiliser les apports du courant de la sociologie pragmatique et de la sociologie de la traduction (ANT : Actor Network Theory) afin de définir le processus de relation de conseil. À partir d’une démarche qualitative, nous avons identifié un modèle de la relation de conseil, appelé LES (Listening, Support, Ethic) décrivant ses trois principales variables (nommées « attributs essentiels ») dans le processus d’opération de traduction de la relation de conseil.L’apport managérial est conséquent car il concerne les acteurs du conseil (conseil en stratégie, management, opérationnels et également les experts-comptables et auditeurs) et quasiment l’ensemble des entreprises de toutes tailles qui font appel ou peuvent solliciter un prestataire pour les accompagner dans leurs activités
Consultancy services have been developing continuously for several decades and the client-consultant relationship appears according to the work in management sciences as an essential explanatory factor of their performance. This literature review shows that the topic of consulting remains underdeveloped, especially in France, and that it will require significant development in the coming years, including through the change in environments and professional practices. Furthermore, most of the studies focus on the consultant and rather little on the advisory relationship. Thus our work aims to contribute to a better understanding of what it is and its dynamics.In this research, we propose to use the contributions of the current of pragmatic sociology and translation sociology (ANT: Actor Network Theory) in order to define the process of the consultancy relationship. Through a qualitative approach, we identified a model of the consulting relationship, called LES (Listening, Support, Ethic) describing its three main attributes (called "essential attributes") in the process of translating the consulting relationship.The managerial contribution is significant because it concerns the actors of consulting (strategy consulting, management, operational and also chartered accountants and auditors) and almost all companies of all sizes that call upon or can solicit a service provider to support them in their activities

Abstract:

This study examines how consumers perceive the overall quality and similarity/fit of the brand extensions (Nike camera, Nike socks, and Nike golf balls) in relation to the original brand (Nike athletic shoes) and how these perceptions influence their attitudes towards the extensions. The researcher proposes that the perceived overall quality of the brand extensions will be congruent to that of the original brand and that the attitude towards the brand extensions will be favourable only when there is a perceived similarity/fit between the brand extensions and the original brand. In order to get these insights, the study surveyed 147 undergraduate and postgraduate students from the University of the Western Cape across all faculties. A non-probability convenience sampling method was used to access respondents. To collect data, qualitative and quantitative methods were employed using a questionnaire which consisted of open-ended and closed-ended questions in the form of free associations technique and 5-point Likert scales. The data gathered was analysed by means of descriptive statistics and Spearman correlation coefficient. The findings indicate two things. (1) respondents only perceived Nike socks&rsquo
overall quality to be congruent to the original brand, Nike athletic shoes. (2) respondents only perceived Nike socks to be strongly similar to the original brand, Nike athletic shoes.

A Chapada do Apodi vem se destacando como um promissor polo de agricultura irrigada em virtude da potencialidade agrÃcola dos seus solos. Considerando o uso intensivo desses solos, e partindo da hipÃtese de que o Srelativo Ã sensÃvel Ãs alteraÃÃes na estrutura do solo e, portanto, se correlaciona com os atributos da fraÃÃo porosa, o presente estudo objetivou avaliar as alteraÃÃes fÃsicas de um Cambissolo sob cultivo de abacaxi e verificar a correlaÃÃo entre o Ãndice Srelativo e os atributos da fraÃÃo porosa. A Ãrea avaliada tem em seu centro as coordenadas 5Â 08' 05" S e 37Â 54' 49" W e Ã cultivada hÃ oito anos com abacaxi (Ananas comosus L. Merril), cultivar PÃrola. O suprimento de Ãgua se dÃ, via de regra, por sistema de irrigaÃÃo do tipo gotejamento e o solo Ã classificado como Cambissolo. Para fins de avaliaÃÃo da qualidade fÃsica, foram contempladas 2 situaÃÃes do solo: sob cultivo e sob mata secundÃria atÃ a profundidade de 0,3 m, nas camadas de 0-0,1, 0,1-0,2 e 0,2-0,3 m. Nestas camadas foram coletadas amostras de solo com estruturas deformada e indeformada para a realizaÃÃo das anÃlises fÃsicas, a saber: granulometria, densidade de partÃculas e do solo, permeabilidade intrÃnseca do solo ao ar e curva de retenÃÃo de Ãgua pelo solo (a partir desta, foram calculados os Ãndices S e Srelativo). Foi avaliada a relaÃÃo do Ãndice Srelativo com os atributos: densidade do solo, porosidade total, macroporosidade, microporosidade, porosidade de aeraÃÃo, permeabilidade intrÃnseca do solo ao ar e continuidade de poros. Considerou-se o delineamento inteiramente casualizado com esquema em parcelas subdivididas 2x3x5 (duas situaÃÃes de solo: sob cultivo e mata secundÃria; trÃs camadas de solo: 0-0,1, 0,1-0,2 e 0,2-0,3 m; cinco repetiÃÃes). Foram aplicados os testes de Kolmogorov-Smirnov para verificar a normalidade dos dados, F para a anÃlise de variÃncia e de Tukey para a comparaÃÃo de mÃdias dos tratamentos, todos a 5% de probabilidade. A relaÃÃo entre atributos da fraÃÃo porosa e o Srelativo foi avaliada por anÃlises de regressÃo e de correlaÃÃo. Concluiu-se que o Ãndice Srelativo Ã sensÃvel Ãs alteraÃÃes impostas Ã estrutura do solo e, portanto, pode ser utilizado como indicador para quantificar mudanÃas na disposiÃÃo de seus constituintes; os demais indicadores utilizados para aferir a qualidade fÃsica do solo corroboraram o Srelativo ao evidenciarem que a Ãrea sob cultivo com abacaxi apresenta estrutura fÃsica melhor que a Ãrea sob mata secundÃria; e o Ãndice Srelativo apresenta correlaÃÃo com atributos da fraÃÃo porosa do sol
The Apodi Plateau has emerged as a promising pole of irrigated agriculture because of its soils agricultural potential. Considering the intensive use in these soils and assuming that the Srelative is sensitive to these changes and is related directly to the attributes of the porous fraction, this study aims to evaluate changes in physical quality of a Cambisol under pineapple crop and measure the relationship between Srelative index and porous fraction attributes. The area to be assessed at its center has the 5Â 08' 05" S and 37Â 54' 49" W coordinates. This is an area planted eight years ago with pineapple (Ananas comosus L. Merril) Pearl cultivar. The water supply is usually by drip irrigation and the soil is classified as Cambisol. In order to evaluate the physical quality, two soil situations were considered: under crop and native forest to a depth of 0.3 m, in the layers of 0-0.1, 0.1-0.2 and 0.2-0.3 m. In these layers disturbed and undisturbed soil samples were collected and submitted to the following physical analyses: particle size distribution, particle density, bulk density, soil air intrinsic permeability and soil water retention curve (from which S and Srelative indices were calculated). The relation of the Srelative index with the following attributes was evaluated: bulk density, porosity, macroporosity, microporosity, aeration porosity, soil air intrinsic permeability and pore continuity index. A completely randomized design was adopted with split plot scheme 2x3x5 (two soil situations: under crop and native forest; three layers: 0-0.1, 0.1-0.2 and 0.2-0.3 m; five replications). Kolmogorov-Smirnov tests were applied to verify the data normality, F for the variance analysis and Tukey for treatments means comparison, all at 5% probability. The relationship between porous fraction attributes and Srelative index was evaluated by regression analyses. It was concluded that Srelative index is sensitive to the changes imposed to the soil structure and, therefore, can be used as an indicator to quantify changes in the arrangements of its constituents; the other soil physical quality indicators agreed with Srelative showing that the area under pineapple cultivation has a better physical structure than the area under secondary forest; and Srelative index shows correlation with soil porous fraction attributes

Abstract:

This study content analyzed interest group and candidate tweets from the 2020 American presidential election to determine what issues and substantive attributes were most salient on interest group and candidate agendas during the "hot phase" of the campaign. Cross-lagged correlations were conducted during two time periods from Labor Day to Election Day 2020 to measure agenda building effects. These tests were conducted for Democratic nominee and eventual President Joe R. Biden, and Republican nominee and former President Donald J. Trump. These tests were also conducted for two issue-based interest groups: Everytown for Gun Safety and the National Rifle Association. Findings indicate that Biden influenced Trump's campaign agenda, but Trump did not influence Biden's. The interest groups showed reciprocal influence with each other. Given the unprecedented nature of the 2020 election, the candidates were largely talking about the same issues. However, substantive attributes reveal the candidates' true issue agenda. This study offers methodological innovation by utilizing NVivo for content analysis.
Master of Arts
This study examined tweets from 2020 presidential candidates Donald J. Trump and Joseph R. Biden, as well as the National Rifle Association, a gun rights advocacy organization, and Everytown for Gun Safety, a gun control advocacy organization. These tweets were examined from September 7 to November 3, 2020, from Labor Day until Election Day. For the presidential candidates, it was found that although candidates were talking the same general campaign issues, they were using different substantive attributes when speaking of them. The findings also revealed that Biden was successful at influencing Trump's Twitter focus during the examined time period. Tweets from advocacy organizations were tested for presence of gun-related issues. The advocacy organizations spoke about the same issues as the other, but neither group was successful at influencing what the other said. This study highlights the importance of digital political public relations.

Abstract:

A new operationalization was used to model a schema-based approach to moral judgment, as well as compare it to predictions based on the Social Intuitionist Model. Judgments were made about the moral wrongness of killing different animals. At Time 1, only moral judgments were made. At Time 2 judgments were made again, with questions and scales relating to attributing morally relevant cognitive capacities also included; further, two randomized conditions varied the presentation order of the scales. Differences between Time 1 and 2 indicated a reversed perspective-taking effect, with animals of lower capacities rated less empathically at Time 2. Affective ratings and attributed capacities were compared as different predictors, showing attributed capacities being more powerful. A group comparison was also made between active animal rights proponents and non-proponents, showing differences on several factors. These and other findings are discussed with relation to the Social Intuitionist Model and a schema-based account of morality.

Full text

Abstract:

Studies have shown that faults exhibit complex geometries that are often highly simplified and cross sections may not be sufficient to highlight the spatial variation of fault surface topography and the complex relationship with the wall rock. The main contributions of this thesis to structural geology are novel methods for investigating links between fault shape and wall rock structure. Curvature plots of sixteen faults show that thrust faults in deepwater Niger Delta exhibit corrugations on a range of wavelength and amplitude. The corrugations are characterized by large-scale anticlastic and synclastic geometries parallel to fault transport direction. The structure of the volumes in the immediate vicinity of the faults was investigated using slices of seismic attribute data sampled parallel and adjacent to thirteen faults. In half of the faults the hanging wall is more disrupted than the footwall, while in the other half the footwall is more disrupted than the hanging wall, implying that thrust zones exhibit complex geometries that existing models have yet to address. In addition, disruptions near fault surfaces may be related to discrete zones of intense fault surface maximum curvature, anomalous surface gradient and change in pattern of anticlastic and synclastic fault Gaussian surface curvature in the fault transport direction. No significant wall rock disruption was observed where fault surface curvature is planar.

Syftet med studien har varit att undersöka musikens funktion för människor och deras relation till musik, låttext och attribut i kontakt med musik i olika sammanhang. En empirisk undersökning i intervjuform har gjorts bland fyra akademiker från fyra olika studieområden, två kvinnor och två män. De fyra akademikerna har gemensamt att de lever på samma område och att de under fritiden kommer i kontakt med, både med varandra och med musikgenren dance musik. Undersökningen fokuseras därför på dessa akademikers förhållande till och användning av dance och vad för funktioner musiken har för dem. Litteratur och tidigare forskning används för att förtydliga begrepp, jämföra likheter och skillnader med akademikernas svar.

Abstract:

La thèse cherche à comprendre le processus de formation de la satisfaction des consommateurs. Elle a pour objet de caractériser les relations entre les attributs et la satisfaction globale ou "fonctions de contribution" des attributs à la satisfaction, pour un service : le chauffage électrique sur le marché résidentiel français. Cette recherche explore également la dynamique de ces relations. A l'aide d'une approche multi-méthodes, la thèse montre que ces fonctions peuvent être linéaires et non linéaires, et qu'elles évoluent dans le temps. Une première recherche, qualitative, confirme l'existence des quatre principales fonctions de contribution identifiées dans la littérature. Deux fonctions non linéaires (les attributs qui ne contribuent qu'à la satisfaction d'une part, et les attributs qui ne contribuent qu'à l'insatisfaction d'autre part), une fonction linéaire et une fonction secondaire (pas de relation à la satisfaction globale) sont ainsi identifiées. La seconde recherche, quantitative, montre l'existence de six principales fonctions de contribution. Elle repose sur l'analyse d'un panel de 286 individus portant sur six années consécutives. Les méthodes préconisées dans la littérature pour étudier les relations entre les attributs et la satisfaction sont testées et comparées. Une méthode de classification originale, les cartes auto-organisatrices de Kohonen, est ensuite utilisée. Les six fonctions alors identifiées comprennent les quatre fonctions précédentes ; une fonction exprimant un effet d'assimilation-contraste de la satisfaction sur attribut à la satisfaction globale ; et une fonction à rendement décroissant à la satisfaction globale intégrant un seuil. Cette méthode neuronale met également en évidence que les fonctions de contribution des attributs changent dans le temps pour le service étudié. Les implications managériales sont alors précisées.

Abstract:

Nos últimos anos, observa-se no Brasil um crescimento no número de programas de relacionamento sendo oferecidos por empresas dos mais diversos segmentos. Esses programas podem ser apresentados de diversas formas, tais como acúmulo de pontos, descontos em rede credenciada, trocas por milhas aéreas, entre outros. O intuito desses programas é aproximar os clientes das empresas participantes e, por consequência, aumentar sua satisfação perante as empresas que os oferecem. O presente trabalho buscou identificar, através de pesquisa bibliográfica, documental e de campo, realizadas com executivos de marketing e usuários, quais os principais atributos que devem compor um clube de vantagens. As variáveis identificadas foram avaliadas por grupos de 30 executivos e 122 usuários, considerando uma escala de 5 pontos. Análises estatísticas comparando as médias desses dois grupos serviram para testar a existência de diferenças perceptivas (gaps) entre as expectativas dos usuários e as avaliações feitas pelos gestores que contratam tais serviços, conforme proposto por Parasuraman, Zeithalm e Berry (1985). Objetivou-se ainda identificar se clubes de vantagens contribuem para a satisfação dos usuários com as empresas que os oferecem.
In recent years, there has been an increase in the number of Relationship Programs offered in Brazil by companies from a wide range of segments. These programs can be presented in a variety of ways, such as point accumulation, accredited network discounts, air mile exchanges, among others. The purpose of these programs is to bring customers closer to the participating companies and, consequently, increase their satisfaction with the companies that offer them. The present work sought to identify, through bibliographical research, documentary and field survey, conducted with marketing executives and users, which are the main attributes that should compose a club of advantages. The identified variables were evaluated by groups of 30 executives and 122 users considering a 5 point scale. Statistical analyzes comparing the means of these two groups served to test the existence of gaps between users expectations and the evaluations made by the managers that hire such services, as proposed by Parasuraman, Zeithalm and Berry (1985). The objective was also to identify if clubs of advantages contributes to the satisfaction of the users with the companies that offer them.

Abstract:

The purpose of this dissertation is to assess digital geo-referenced information and standards for exchanging such information, especially the South African National Exchange Standard (NES). The process of setting up a standard is exacting. On the one hand, the process demands a thorough scrutiny and analysis of the objects to be standardised and of all related concepts. This is a prerequisite for ensuring that there is unanimity about their meaning and inter-relationships. On the other hand, the process requires that the standard itself be enunciated as succinctly, comprehensibly and precisely as possible. This dissertation addresses both these facets of the standards process in the context of standards for exchanging digital geo-referenced information. The dissertation begins with an analysis of geo-referenced information in general, including digital geo-referenced information. In chapters 2 and 3, the various aspects of such information are scrutinised and evaluated in more detail. The examination of concepts is backed up by a comprehensive Glossary of terms in the domain under discussion. Chapter 4 examines the nature of standards. It also proposes a novel way to approach a standard for the exchange of digital geo-referenced information: namely, that it can be viewed as a language and can accordingly be specified by a grammar. To illustrate the proposal, NES is fully specified, using the Extended Backus-Naur Form notation, in an Appendix. Apart from the advantages of being a succinct and precise formal specification, the approach also lends itself to deploying standard tools such as Lex and yacc for conformance testing and for developing interfaces to NES, as illustrated in a second appendix. As a final theme of the dissertation, an evaluation of such standards is provided. Other standards that have been proposed elsewhere for purposes similar to that of NES are surveyed in chapter 5. In chapter 6, features of NES are highlighted, including the fact that it takes a relational approach. Chapter 7 concludes the dissertation, summarising the work to date, and looking ahead to future work. AFRIKAANS : Die doel van hierdie verhandling is om versyferde geo-verwysde inligting en standaarde vir die uitruil van sulke inligting te ondersoek, met spesifieke verwysing na die Suid- Afrikaanse Nasionale Uitruilstandaard (NES). Die proses om ’n standaard op te stel is veeleisend. Aan die een kant vereis die proses ’n volledige bestudering en ontleding van die objekte wat gestandaardiseer gaan word, asook van al die verwante konsepte. Hierdie is ’n voorvereiste om te verseker dat daar oor hul betekenisse en onderlinge verwantskappe eenstemmigheid bestaan. Aan die ander kant vereis die proses dat die standaard so kernagtig, volledig en presies moontlik gestel moet word. Hierdie verhandeling spreek beide hierdie fasette van die standaardiseringsproses aan, en wel in die konteks van standaarde vir die uitruil van versyferde geo-verwysde inligting. Dié verhandling begin met ’n oorhoofse analise van geo-verwysde inligting, insluitend versyferde geo-verwysde inligting. In hoofstukke 2 en 3 word verskeie aspekte van dié inligting in meer detail ondersoek en geëvalueer. Hierdie ondersoek van konsepte word deur ’n omvattende woordelys van terme in die veld onder bespreking gesteun. Hoofstuk 4 ondersoek die aard van standaarde. Dit stel ook ’n nuwe manier voor om ’n standaard vir die uitruil van versyferde geo-verwysde inligting te benader, naamlik dat dit as ’n taal beskou kan word, en dat dit gevolglik deur middel van ’n grammatika gespesifiseer kan word. Om die voorstel te illustreer, word NES volledig in ’n aanhangsel deur middel van die Uitgebreide Backus-Naur Vorm notasie gespesifiseer. Afgesien van die voordeel van ’n kernagtige en presiese formele spesifikasie, ondersteun die benadering ook standaardgereedskap soos Lex en yacc wat vir konformeringstoetsing en vir NES koppelvlakke gebruik kan word, soos in ’n tweede aanhangsel illustreer word. As ’n finale tema van die verhandeling word ’n evaluasie van tersaaklike standaarde voorsien. Standaarde wat elders vir soortgelyke doeleindes aan dié van NES voorgestel is, word oorsigtelik in hoofstuk 5 beskou. In hoofstuk 6 word kenmerkende eienskappe van NES uitgelig, insluitend die feit dat dit op ’n relasionele benadering gebaseer is. Hoofstuk 7 sluit die verhandeling af met ’n opsomming van werk tot op datum en ’n blik op toekomstige werk.

Abstract:

Diversos problemas práticos envolvendo sistemas de visão computacional, tais como vigilância automatizada, pesquisas de conteúdo específico em bancos de dados multimídias ou edição de vídeo, requerem a localização e o reconhecimento de objetos dentro de seqüências de imagens ou vídeos digitais. Mais formalmente, denomina-se rastreamento o processo de determinação da posição de certo(s) objeto(s) ao longo do tempo numa seqüência de imagens. Já a tarefa de reconhecimento caracteriza-se pela classificação desses objetos de acordo com algum rótulo pré-estabelecido ou apoiada em conhecimento prévio tipicamente introduzido através de um modelo dos objetos de interesse. No entanto, rastrear e classificar objetos em vídeo digital são tarefas desafiadoras, tanto pelas dificuldades inerentes a esse tipo de elemento pictórico, quanto pelo variável grau de complexidade que os quadros sob análise podem apresentar. Este documento apresenta uma metodologia baseada em modelo para rastrear e reconhecer objetos em vídeo digital através de uma representação por grafos relacionais com atributos (ARGs). Tais estruturas surgiram dentro do paradigma de reconhecimento estrutural de padrões e têm se mostrado bastante flexíveis e poderosas para modelar problemas diversos, pois podem transmitir dados quantitativos, relacionais, estruturais e simbólicos. Como modelo e entrada são descritos através desses grafos, a questão de reconhecimento é interpretada como um problema de casamento inexato entre grafos, que consiste em mapear os vértices do ARG de entrada nos vértices do ARG modelo. Em seguida, é realizado o rastreamento dos objetos de acordo com uma transformação afim derivada de parâmetros obtidos da etapa de reconhecimento. Para validar a metodologia proposta, resultados sobre seqüências de imagens digitais, sintéticas e reais, são apresentados e discutidos.
Several practical problems involving computer vision systems, such as automated surveillance, content-based queries in multimedia databases or video editing require the location and recognition of objects within image sequences or digital video. More formally, the process of determining the position of certain objects in an image sequence throughout time is called tracking, whereas the recognition task is characterized by the classification of such objects according to pre-defined labels or a priori knowledge, typically introduced by means of a model of the target objects. However, tracking and recognition of objects in digital video are not simple tasks, either because of the inherent difficulties of such a pictorial element, or due to the variable level of complexity that the frames under consideration might present. This document presents a model-based methodology for tracking and recognizing objects represented by attributed relational graphs (ARGs) in digital video. These structures have arisen from the paradigm of structural pattern recognition and have proven to be very flexible and powerful for modeling various problems, as they can hold many sorts of data (e.g: quantitative, relational, structural and symbolic). Since both model and input data are described through these graphs, the recognition matter may be interpreted as an inexact graph matching problem, which consists in finding a correspondence between the set of vertices of the input ARG and that of the model ARG. In the next step, object tracking is performed according to an affine transform derived from parameters extracted from the recognition phase. To validate the proposed methodology, results obtained from real and synthetic digital image sequences are presented and discussed.

Abstract:

Cette dernière décennie, la modélisation des villes 3D est devenue l'un des enjeux de la recherche multimédia et un axe important en reconnaissance d'objets. Dans cette thèse nous nous sommes intéressés à localiser différentes primitives, plus particulièrement les fenêtres, dans les façades de Paris. Dans un premier temps, nous présentons une analyse des façades et des différentes propriétés des fenêtres. Nous en déduisons et proposons ensuite un algorithme capable d'extraire automatiquement des hypothèses de fenêtres. Dans une deuxième partie, nous abordons l'extraction et la reconnaissance des primitives à l'aide d'appariement de graphes de contours. En effet une image de contours est lisible par l'oeil humain qui effectue un groupement perceptuel et distingue les entités présentes dans la scène. C'est ce mécanisme que nous avons cherché à reproduire. L'image est représentée sous la forme d'un graphe d'adjacence de segments de contours, valué par des informations d'orientation et de proximité des segments de contours. Pour la mise en correspondance inexacte des graphes, nous proposons plusieurs variantes d'une nouvelle similarité basée sur des ensembles de chemins tracés sur les graphes, capables d'effectuer les groupements des contours et robustes aux changements d'échelle. La similarité entre chemins prend en compte la similarité des ensembles de segments de contours et la similarité des régions définies par ces chemins. La sélection des images d'une base contenant un objet particulier s'effectue à l'aide d'un classifieur SVM ou kppv. La localisation des objets dans l'image utilise un système de vote à partir des chemins sélectionnés par l'algorithme d'appariement
This last decade, modeling of 3D city became one of the challenges of multimedia search and an important focus in object recognition. In this thesis we are interested to locate various primitive, especially the windows, in the facades of Paris. At first, we present an analysis of the facades and windows properties. Then we propose an algorithm able to extract automatically window candidates. In a second part, we discuss about extraction and recognition primitives using graph matching of contours. Indeed an image of contours is readable by the human eye, which uses perceptual grouping and makes distinction between entities present in the scene. It is this mechanism that we have tried to replicate. The image is represented as a graph of adjacency of segments of contours, valued by information orientation and proximity to edge segments. For the inexact matching of graphs, we propose several variants of a new similarity based on sets of paths, able to group several contours and robust to scale changes. The similarity between paths takes into account the similarity of sets of segments of contours and the similarity of the regions defined by these paths. The selection of images from a database containing a particular object is done using a KNN or SVM classifier
