Spyropoluou, Eirini. "Local pattern mining in multi-relational data." Thesis, University of Bristol, 2013. http://ethos.bl.uk/OrderDetails.do?uin=uk.bl.ethos.654116.
Full textAbstract:
Multi-relational data mining has so far been synonym to methods based on Inductive Logic Programming (ILP) , which discover frequent first-order logic rules in the data. This is due to the fact that ILP conveniently captures the multi-relational structure, while there has not been a suitable pattern syntax extension of an itemset for the case of multi-relational data. Local pattern mining methods have mostly focused on mining a single relation. A common strategy for mining multi-relational data (MRD) has been to apply frequent items et mining on the join of all database relations. However, when flattening the data in this way, important structural information is lost and itemsets do not capture all the associations in the data. This thesis describes our research that led to a new approach for local pattern mining in multi-relational data. The final result of this research is summarised as follows. We define the new pattern syntax of Maximal Complete Connected Subsets (MCCSs) for MRD with binary relations, which captures well the structure of the original data. We additionally propose the generalisation of MCCSs, called N-MCCSs, for MRD containing relations of any arity. We demonstrate how N-MCCSs contain tiles [27] and n-sets [16] as special cases. Furthermore, we propose RMiner, an efficient algorithm to mine MCCSs and N -RMiner an efficient algorithm to mine N-MCCSs. We show experimentally that N-RMiner, while applicable to MRD in general, when applied to a Single n -ary relation, considerably outperforms the state of the art algorithm for mining n-sets [16] on real world datasets. Finally, this work is incorporated into a general data mining framework for quantifying the subjective interestingness of patterns based the prior information of the user.

Full textAbstract:
Abuse and neglect occurring in childhood have been associated with a number of functional and physiological effects on the brain. This study extends previous research that investigated the quantitative electroencephalogram (qEEG) patterns in children with histories of relational trauma through the inclusion of additional participants and measures. As in previous studies, the relative power, absolute power, and coherence values in children with histories of abuse were compared to the Neuroguide database. Results did not show any significant differences in relative or absolute power in the theta range. Similarly, there were no significant coherence differences. Database comparisons were also made using low resolution electromagnetic tomography (LORETA) in order to determine which sub-cortical brain structures may be affected by abuse or trauma, though there were no significant differences in any frequency (0-30Hz). A review of the literature suggests that the prevalence of mu in normal adults and children ranges from 0 to 19%. The present study found a mu prevalence rate of 60.6% in the children who experienced abuse or neglect. Finally, comparisons were made between participants who demonstrate a mu pattern and those who do not to determine if this pattern is associated with certain behavioral and/or attention problems as assessed by the Child Behavior Checklist (CBCL) and the Tests of Variables of Attention (TOVA), respectively. There were no significant differences between children with a mu pattern versus children who did not exhibit a mu pattern on the Social Problems, Thought Problems, or Attention subscale scores on the CBCL or on the Commission subscale score on the TOVA.

This indirect estimation technique is dependent on a fertility standard - the Booth standard. This standard was developed in 1979 using a selection of 33 Coale-Trussell schedules congruent with high fertility patterns. However, evidence from 61 Demographic and Health Surveys of sub-Saharan countries shows that fertility has decreased to levels that were considered medium fertility at the time the standard was developed. This raises concerns about the continued relevance of the (high fertility) Booth standard. In particular, the standard would appear to consistently underestimate fertility among African women aged 45-49.

Full textAbstract:
Psychology<br>Ph.D.<br>Episodic memory binds together the people, objects, and locations that make up the specific events of our lives, and allows the recall of our past in the service of current and future goals. Recent models of memory have posited that the hippocampus instantiates computations critical for episodic memory including mnemonic discrimination, relational binding, and holistic retrieval. Collectively, this set of studies aim to chart the ontogeny of each key components of episodic memory. We found robust improvements in children’s abilities to form complex relational structures and to make fine-grained discrimination for individual items from age 4 to age 6. However, relational memory dependent on context discrimination appears to follow a more protracted development. Furthermore, relational binding and mnemonic discrimination (item and context levels) undergo age-related decrements in senescence. Despite relatively poor relational binding capabilities, children as young as age 4 are able to retrieve multi-element events holistically, such as successfully retrieving of one aspect of an event predicts the retrieval success of other aspects from the same event. Critically, the degree of holistic episodic retrieval increases from age 4 to young adulthood. This multi-process approach provides important theoretical insights into lifespan profile of episodic memory.<br>Temple University--Theses

Full textAbstract:
This licentiate thesis focuses on surface patterns, spatiality, and pattern relations in textile design, and aims to explore surface patterns as spatial definers and what they mean in the context of surface patterns. A secondary focus relates to applying conceptual spatial determinations as alternative design variables in design processes, and exploring how these could be used to define and analyse pattern relations. Through a series of exploratory design experiments that used printed and projected surface patterns in a three-dimensional setting, which were documented using photographs and film, the notion of pattern relations, wherein scale was used as a design variable, was explored. The outcome of the experiments showed the expressional possibilities that surface patterns may provide in a defined space, and how these are connected to pattern relations. In order to encourage an accompanying discussion regarding alternative methods of analysing surface patterns, the construction of a theoretical model was initiated. Workshops with design students were used as another practical method in this work. The results showed that there is great potential in using conceptual spatial determinations to define pattern relations by viewing surface patterns as spatial definers, rather than taking a traditional perspective on their functions. Another outcome is the theoretical model, which proposes a specific approach to pattern relations. This research demonstrates how conceptual spatial determinations can benefit the textile design process, as well as design teaching, which could in turn provide the field with new expressions that may lead to a change in or fruitful addition to the practice.

Full textAbstract:
Model View Controller (MVC) software architecture is widely spread and commonly used in application’s development. Therefore generation of data layer for the database model is able to reduce cost and time. After research on current Object Relational Mapping (ORM) tools, it was discovered that there are generating tools like Data Access Object (DAO) and Hibernate, however their usage causes problems like inefficiency and slow performance due to many connections with database and set up time. Most of these tools are trying to solve specific problems rather than generating a data layer which is an important component and the bottom layer of database centred applications. The proposed solution to the problem is an engineering approach where we have designed a tool named Generated Intelligent Data Layer (GIDL). GIDL tool generates small models which create the main data layer of the system according to the Database Model. The goal of this tool is to enable and allow software developers to work only with object without deep knowledge in SQL. The problem of transaction and commit is solved by the tool. Also filter objects are constructed for filtering the database. GIDL tool reduced the number of connections and also have a cache where to store object lists and modify them. The tool is compared under the same environment with Hibernate and showed a better performance in terms of time evaluations for the same functions. GIDL tool is beneficial for software developers, because it generates the entire data layer.

Full textAbstract:
Esta tese de doutorado aborda os tópicos de modelagem e de reconhecimento de objetos estruturados, ou sistemas estruturados de objetos, em imagens. Um objeto ou sistema estruturado é aquele que pode ser descrito através de elementos primitivos que o compõem e pelas relações existentes entre esses elementos. Por exemplo, uma aeronave pode ser descrita pelos seguintes elementos primitivos: asas direita e esquerda, fuselagem e cockpit. O aspecto relacional de um objeto estruturado direciona sua representação computacional e seu reconhecimento em imagens ao paradigma estrutural de reconhecimento de padrões. Contudo, a variabilidade das características dos seus elementos primitivos é melhor representada através do paradigma estatístico de reconhecimento de padrões. Devido à complementaridade dos paradigmas, a conjunção dessas abordagens é um tema de pesquisa de interesse atual. Para conjugar esses dois aspectos, esta tese propôs uma metodologia que combina o conhecimento a priori das relações que caracterizam um objeto estruturado com dados estatísticos coletados de amostras desse objeto, num modelo híbrido denominado grafo estatístico-relacional (GER). Segundo essa representação, foi estudada uma abordagem probabilística para reconhecer um objeto estruturado em imagens. Nesse cenário, o GER modelo é considerado uma variável aleatória, enquanto uma rotulação de uma imagem de entrada é interpretada como uma potencial observação do modelo. A tarefa de reconhecimento foi então formulada como um problema de otimização, que busca maximizar a probabilidade da observação de acordo com o modelo. O método foi aplicado à modelagem de órgãos abdominais em imagens de ressonância magnética não-contrastadas. Esses órgãos apresentam um arranjo espacial consistente em imagens distintas, além de propriedades de aparência e anatômicas variáveis, o que vem ao encontro da proposta da representação por GER e da abordagem probabilística para o reconhecimento dos órgãos em novas imagens.<br>The purpose of this thesis was to propose a formalism for the problems of modeling and recognition of a structured object, or a system of structured objects, in images. A structured object is one that may be described in terms of its compound primitive elements and their inherent relations. For instance, an aircraft may be described in terms of the following primitives: right and left wings, fuselage, and cockpit. The relational aspect of structured objects leads these problems to solutions in structural pattern recognition, which describes patterns as primitives and relations. Nevertheless, the variability of primitive elements and of their relations is better modeled by traditional statistical pattern recognition methods. Because of the complementary capabilities of these approaches, the fusion of both has recently been pointed out as a trend in computer vision. To consider these sources of information, the methodology presented herein combines relational cues inherent to a structured object with statistical information learned from a set of object samples. A hybrid model of a structured object is represented by means of a statistical relational graph (SRG). The SRG is a prototype attributed relational graph (ARG) in which nodes represent primitive elements and arcs link nodes representing related primitives. Each node or arc is associated with attributes which are parameters of probability distributions that describe random variables representing primitive or relational attributes. Based on this representation, a probabilistic approach was proposed to tackle the problem of recognizing a structured object in an input image. The model SRG is interpreted as a random variable, whereas a labeling of the input image is considered a potential observation of the model. The recognition task was formulated as the optimization of an objective-function that is actually a probability measure to be maximized. The proposed approach was applied to the modeling of abdominal organs in non-contrasted magnetic resonance images. These organs present consistent spatial arrangement in distinct images, as well as varying appearance and anatomical properties, which meet the principle of the SRG representation and the associated probabilistic recognition scenario.

Holmes, Carol A. V. "Relational patterns of being in communicative psychotherapy." Thesis, Middlesex University, 2001. http://eprints.mdx.ac.uk/13629/.
Full textAbstract:
Communicative Psychotherapy is characterised by its distinctive focus on the immediate therapeutic interaction. The approach identifies the client's unconscious curative abilities to guide the treatment process, while also acknowledging the practitioner's potential to also disturb the therapeutic procedure. The major thrust of Communicative Psychotherapy is related to the significance of death anxiety. This notion is consistently addressed around the boundary issues (as they arise) of the therapeutic environment. The approach emphasizes the interpersonal influence that this ongoing existential concern has on the quality of the therapeutic relationship. The school of Existential Phenomenology is generally viewed as antagonistic to theories of human behaviour that stress the role of the unconscious. The research has examined the connections between some major existential themes, taken from a specific tradition of European existentialism and the communicative approach to psychotherapy. The discourse has explored and juxtaposed some key existential concepts of being in the world in order to clarify the interpersonal communicative focus on being - between client and therapist in the consulting room. The work has sought to display a common philosophical thread that unites existentialism to the communicative model. The research has also systematically applied and revealed a link between fractal patterns that signify disorder in Dynamical Systems Theory and communicative practice, which is principally focused on the client's recurring narrative themes that relate to the boundary disturbances in the therapeutic system. The context statement has extended, amplified and grounded the main topic of the thesis by integrating three further features. (1) By augmenting the triple link between Existential Philosophy, Chaos Theory and Communicative Psychotherapy. (2) By displaying the relational principles that are implied in the three manifestly divergent disciplines. (3) By illustrating the phenomenological aspects of the communicative method.

Bennett, Megan S. "Exploring Relational Communication Patterns in Preferral Intervention Teams." NCSU, 2010. http://www.lib.ncsu.edu/theses/available/etd-03262010-134940/.
Full textAbstract:
The purpose of this research was to understand the relational communication patterns that characterize school-based prereferral intervention teams (PITs). Prior research has suggested that although many states either require or recommend PITs, little is known about what occurs during PIT meetings (Truscott, Cohen, Sams, Sanborn, & Frank, 2005). A relational communication perspective emphasizes that within interpersonal interactions (such as those that occur in group-based situations), speakers are constantly redefining their roles, positions, and relationship through conversations (Erchul, Grissom, & Getty, 2008). A popular way of studying relational communication in dyadic or group situations is through coding systems such as the Family Relational Communication Control Coding System (FRCCCS; Heatherington & Friedlander, 1989). In this study, 15 PIT meetings were used as the basis of analyses and each meeting was audiotaped, transcribed, and coded using the FRCCCS. Additionally, each coder completed the PIT Meeting Evaluation Coding Sheet that assessed participantsâ adherence to a traditional problem-solving framework. Important results included: (a) relatively consistent domineeringness (i.e., attempted influence) scores, with the exception of the referring teacher; (b) overall relatively consistent dominance (i.e., successful influence) scores; (b) significantly greater (p < .05) domineeringness by the school psychologist when compared to the referring teacher; and (c) no significant differences in dominance scores between the school psychologist and teacher. In sum, the current study represents an important first step in understanding communication patterns in school-based groups, which will continue to be important as schools transition to using response-to-intervention (RTI) models of service delivery.

L'extracció d'informació requereix una quantitat considerable de coneixement lingüístic. La especificitat d'aquest
coneixement suposa un inconvenient de cara a la portabilitat dels sistemes, ja que un canvi d'idioma, domini o estil té un
cost en termes d'esforç humà. Durant dècades, s'han aplicat tècniques d'aprenentatge automàtic per tal de superar aquest

la disponibilitat de grans col·leccions de documents, esdevenen necessàries aproximacions completament nosupervisades
per tal d'explotar el coneixement que hi ha en elles.
La proposta d'aquesta tesi és la d'incorporar tècniques de clustering a l'adquisició de patrons per a extracció d'informació,
per tal de reduir encara més els elements de supervisió involucrats en el procés En particular, el treball se centra en el
problema de la detecció de relacions. L'assoliment d'aquest objectiu final ha requerit, en primer lloc, el considerar les

de clustering adequats a les nostres necessitats; i en tercer lloc, el disseny de procediments d'adquisició de patrons que
incorporessin la informació de clustering.
Al final d'aquesta tesi, havíem estat capaços de desenvolupar i implementar una aproximació per a l'aprenentatge de

Information extraction requires a significant amount of linguistic knowledge. The specificity of such knowledge supposes a
drawback on the portability of the systems, as a change of language, domain or style demands a costly human effort.
Machine learning techniques have been applied for decades so as to overcome this portability bottleneck¿progressively
reducing the amount of involved human supervision. However, as the availability of large document collections increases,
completely unsupervised approaches become necessary in order to mine the knowledge contained in them.
The proposal of this thesis is to incorporate clustering techniques into pattern learning for information extraction, in order to
further reduce the elements of supervision involved in the process. In particular, the work focuses on the problem of relation
detection. The achievement of this ultimate goal has required, first, considering the different strategies in which this
combination could be carried out; second, developing or adapting clustering algorithms suitable to our needs; and third,
devising pattern learning procedures which incorporated clustering information.
By the end of this thesis, we had been able to develop and implement an approach for learning of relation detection patterns
which, using clustering techniques and minimal human supervision, is competitive and even outperforms other comparable
approaches in the state of the art.

Approved for public release; distribution is unlimited<br>The rise of political Islam in the Muslim Middle East is a critical development certain to shape political and social change in the region for decades to come. Political Islam is bound to exert a particularly strong influence on civil-military relations due to the legacy of military dominance of state institutions. Drawing on the reform experiences in Iran, Turkey, and Egypt, this thesis argues that a distinct pattern of civil-military relations is beginning to emerge in which Islamist governments rely on ideology to mobilize and ensure the loyalty of supporters to a degree that clearly distinguishes them from their authoritarian and democratic predecessors. While these Islamist-dominated governments have utilized some democratic control mechanisms in their efforts to expand their control of the government and bring the military under civilian control, this owes more to expediency than to a genuine commitment to democratic reform. Although each Islamist political organization interprets the Islamization of the state differently and some could be considered politically or socially liberal, the primary characteristic of any Islamist political organization is to Islamize the state rather than to democratize ita characteristic that has important implications for how Islamist governments assert their authority over the military.

Full textAbstract:
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.

Banim, Maura. "Occupying houses : the social relations of tenure." Thesis, Durham University, 1986. http://etheses.dur.ac.uk/7095/.
Full textAbstract:
With the shifts in housing tenure patterns in post-war Britain being so decisive and apparently relentless, one of the main issues that concerns those involved with housing is that of the impact of mass home-ownership - especially on those groups new to the tenure. These concerns range from the possible effect of new home-owner ship on voting patterns and political allegiances; to the financial hardship that seems to be increasingly falling on low income owner occupiers; and to the domestic and familial changes entailed by two-income mortgages. It is towards assessing the impact of these changes more fully, that this thesis is aimed. In order to better understand the origins and effects of tenure shifts, two main points are made. Firstly, that the occupation of houses (of whatever tenure) is an issue that involves practically everyone in society, either as individual tenants/owners/homeless persons, or as groups of ratepayers/voters/neighbourhoods or as business/financial/political interests, or as any combination of these. Secondly, it is emphasised that the terms and conditions of the various tenures have been created and have been altered and adapted over time, and that the definition and meaning of the tenures is as crucial to the housing debate as the well-recognised tenure trends. Consequently, it is argued that the changing patterns and definitions of tenures have a crucial and far-reaching effect on wider social relations in society whilst, at the same time, these changes originate from and in part reflect, already occurring events in civil society.

These dimensions are complexity of object representations, affect tone of relationship paradigms, capacity for emotional investment in relationships and understanding of social causality.</p>

This work is exploring the rectangle as a pattern construction. It is the most recognised geometric shape, can it still provide us with new expressions in fashion? This project is conducted through clear restrictions in the method, and through draping translated into garments through flat pattern construction. The result is a collection with a complex expression, mixing poetic shapes with playful prints full of contrast, which signifes harmony but does not follow the classical notions of beauty. The value of this work lies in the finding of new expressions in fashion, proposing that it is of utmost importance to challenge what we think we know to be true.

Es gibt wenige Erkenntnisse über den Zusammenhang zwischen Lamivudin induzierten Resistenzmutationen und Hepatitis B Genotypen. Die vorliegende Studie untersucht das Verhältnis zwischen diesen Mutationen und den Hepatitis B Genotypen A-D.
Die Datenbank der US-amerikanischen Kongressbibliothek (Pubmed) wurde nach den Begriffen „HBV OR hepatitis B”, „YMDD”, „genotype”, und „lamivudine” durchsucht. Alle in dieser Suche gefundenen Arbeiten, die bis Juni 2009 veröffentlicht worden waren, wurden in die Studie eingeschlossen. Die Ergebnisse der Literaturanalyse wurden mit den Hepatitis B-Genomdaten zweier Referenzlabore in Tübingen und Melbourne verglichen.
Insgesamt konnten 29 Arbeiten aus der Datenbankrecherche in die Literaturanalyse eingeschlossen werden. Diese Studien enthielten Daten zu insgesamt 827 Patienten, deren Hepatitis B Genotyp bekannt war und die eine Lamivudinresistenzmutation aufwiesen. In statistischen Untersuchungen konnte nachgewiesen werden, dass die rtM204V-Mutation die dominierende Mutation bei Infektionen mit Genotyp A ist. Dieses Ergebnis konnte durch die Analyse der Genomdaten der Referenzlabore bestätigt werden. Ferner konnte gezeigt werden, dass bei den Genotypen A, B, und D die rtL180M-Mutation hochsignifikant mit der rtM204V-Mutation verknüpft ist.
Die Dissertationsschrift enthält neben dem Artikel „Mutation pattern of lamivudine resistance in relation to hepatitis B genotypes: hepatitis B genotypes differ in their lamivudine resistance associated mutation pattern“ (Damerow, H, Yuen L et al.; J Med Virol. 2010 Nov; 82(11):1850-8) eine Einführung in die Rationale der Studie, eine Zusammenfassung der Ergebnisse sowie ein Fazit.

Full textAbstract:
This study was an investigation of the patterns of relational communication in conjoint behavioral consultation (CBC) for children with behavioral problems. This study compared the patterns of relational communication when different processes (i.e., decision-making versus information gathering) are used to meet the objectives of CBC during the Conjoint Problem Identification Interview (CPII) and the Conjoint Problem Analysis Interview (CPAI). It also explored the relationship between patterns of relational communication and the outcome of CBC. Twenty-one children with identified behavioral problems (ages 3 to 8), the mothers and teachers of these children (i.e., the consultees), and advanced graduate students (i.e., the consultants) participated in this study. Relational communication was measured via the Family Relational Communication Control Coding System (FRCCCS, Heatherington & Friedlander, 1987). The two summary variables that were derived from the FRCCCS are domineeringness and dominance (Courtright, Millar, & Rogers-Millar, 1979; Rogers-Millar & Millar, 1979).The measure of outcome was the improvements in children's target behavior from baseline to intervention at home and at school, as measured by effect size statistics. The extent to which consultants, parents and teachers intent to direct the other and how the others receive their directiveness, appear to vary as a function of the interview as well as the process use to meet objectives within an interview. Some patterns of relational communication were found to be associated with the outcome of consultation. The original contributions as well as the implications of this research are discussed.

Full textAbstract:
This research attempts to extend the application of spatial analysis to the investigation of human agency in social relations. Marcos Llobera's research framework on modelling daily experience and social space showcases great potentials of utilising Geographic Information Systems (GIS) to explore the perception and behaviour of individual agents. By expanding Llobera's work and incorporating Tim Ingold's wayfaring theory to explore the human agency in the context of social relations, this research proposes a new analytical method to investigate social relations through the accumulation of intimate interactions. Exemplified with detailed analysis on two settlements of Kaushi people in Taiwan, the proposed analytical method demonstrates great strength and yields fruitful insights into their social structure and transformation. In addition, this method is particularly instrumental in unravelling specific relations between individuals, as well as between social groups. The application of this method on Kaushi settlements yielded fruitful insights of their social structure and transformation. On the other hand, the side products of this approach can be further employed to investigate the visual structure and movement intensity of a site, as well as to experiment alternative 'what if' scenarios relating to visibility, movement, and interaction. In sum, this research augments the potential of spatial analysis to explore human agency in a social context and lays out a further platform for the investigation of social relations at a settlement scale.

Increased movement rate for females was observed during spring and summer. The breeding season (15 September -15 October) is the most important season for bulls. Our result shows that bulls significantly increase their movement rate during the rut, compared to other times during the fall. Movement rate increased twice compared with female movement rate during this period. No difference was observed during the rutting period for females (15 September- 15 October) compared with no rutting period during fall. During winter time, both sexes retain low movements, mainly caused by energy saving actions. A distinct crepuscular rhythm was exhibited during the summer and fall season, movements were more intense during dawn and dusk hours. No distinct crepuscular rhythm was noticed during winter and spring seasons.</p><p>The traffic intensity at highway E6 in Southwestern Sweden increases during the morning hours and reaches its maximum during midday. Moose in southwestern Sweden crossed highway E6 more often at night time than day time. Thus highway crossings by moose occurred at times of peak moose movements, and traffic volume had lower importance.</p>

Full textAbstract:
Ever since Korea and Japan established kingdoms in the 6th century, both countries greatly influenced each other politically, militarily, socially, culturally, and economically through international exchange. Korea and Japan kept their close relationship throughout history because of geographic proximity. It is also notable that 54 per cent of Japanese males and 66 per cent of Japanese females carry Sino-Korean genes in present-days and there are records that Japan carried a close relationship with Paekche, a kingdom of the Korean peninsula which introduced script, Confucianism, and Buddhism to Japan at an early stage.
In the Medieval Period, Korea and Japan maintained a friendly trade policy but there were incidents such as Mongol invasions, wakō (Japanese pirates) raids and two invasions by Toyotomi Hideyoshi, which worsened the relations between the two countries. And yet, during Japan’s period of isolation (from 1639 to1854), Korea was the only nation with which full and free trade was permitted.
The 20th century is based on invasion and colonisation of Japan over Korea. For 35 years from 1910 to 1945, under the control of Japan, the Japan-Korea relationship was nothing but misfortune: forced labour, suppression of Korean culture and language, press-gangs, sex slaves, and so forth.
The aim in this thesis is to go into greater detail about each significant event and its effect on the relationship between Japan and Korea to uncover some rationale or pattern such as gekokujō (the master being outdone by the pupil, and being treated thereafter with contempt).

Full textAbstract:
My study covers the period from the initial establishment of English representation at the Ottoman Porte with the capitulations of 1580 which established trading and diplomatic rights for English merchants, and the formal establishment of an embassy in 1583. I explore the development of the English embassy at Constantinople from its vulnerable first years through its growth in prestige during the 1620s and 1630s, to the zenith of its influence in the 1660s before the French began to dominate diplomatic business at the Porte. I examine English policy at the Porte from its first tentative attempts to secure a strategic alliance against the Spanish with the Ottomans in the Mediterranean, through the Thirty Years War in which both Ottoman and English authorities found themselves reluctantly embroiled and the domestic troubles which both suffered in the 1640s, culminating with the execution of Ibrahim I in 1648 and Charles I in 1649. I conclude with the period of stabilization in the 1650s when the English authorities reasserted coherent policies at home and abroad during the Protectorate and the Restoration. This was mirrored by a stabilisation of the Ottoman Empire after the first of the Köprülü Grand Viziers took the reins of power in 1656 and reasserted central control over the provinces and over Ottoman vassals on the peripheries of Ottoman territory. The thesis builds on work done on the English commercial expansion in the Levant and the commercial role of the embassy in the Constantinople. I seek to complement existing studies of particular embassies and personalities and to give a broader over-view of the development of Anglo-Ottoman diplomatic relations. I intend to open debate on the development of Ottoman foreign policy and the implementation of Ottoman diplomacy during the seventeenth century well before the Ottoman bureaucracy underwent the westernization which led to it being absorbed into the European diplomatic system during the late eighteenth century. In the introductory chapters I explore the development of diplomacy during this period to establish the different attitudes of the English governments who conducted a largely adhoc diplomacy until the late sixteenth century when they began to open a few key residences abroad, and the Ottoman authorities who maintained a strictly non-reciprocal form of policy with western nations which lay outside the Dar al-Islam or Muslim lands. I discuss the question of the duality of the embassy at Constantinople as both a commercial agency and a state department and examine the potential for conflict between the controlling interests of the Crown and the Levant Company. In two chapters on the domestic situations in England and the Ottoman Empire I assess the priorities of policy and the domestic and financial constraints on an active foreign policy. Both the Ottoman Empire and the English sought to secure their own state through internal stability and external alliances. Both states faced the same problems of hostility from their neighbours, internal rebellion and the need to provide for growing government expenditure. However, England and the Ottoman Empire differed in the way they approached their problems and had different resources to help them carry their policies through. The most notable contrast was that the Ottomans possessed a growing standing army while England relied on ad hoc levies until Cromwell's new model army. These chapters are intended to open the subject to two audiences: the Ottomanist and the Early Modern European/English Historian, and to place the Anglo-Ottoman relationship within a broader diplomatic context. I have divided the thesis into three parts, each exploring a different aspect of diplomatic relations between Whitehall and the Porte, centring on the role of the embassy at Constantinople. The opening of direct diplomatic relations with the Porte was the first sustained diplomatic contact the English had established with a non-Christian nation and formed the model for later diplomatic contacts with non-European nations. As a whole, my study contributes to an understanding of how England adapted to the non-reciprocal diplomacy of the Ottoman Porte and to the operation of diplomacy by a Christian nation in a non-Christian state. I also explore the development of English policy in the Mediterranean and place the Anglo-Ottoman diplomatic relationship in its European context. In part one I examine the function of the etiquette system at the Ottoman Porte and assess the importance of protocol conventions and the extent to which they affected the status of the ambassador and the progress of negotiations. I explore the status of western ambassadors within the Ottoman system and illustrate the adaptability and sophistication of the Forte's ceremonial system. I address the problem of the Forte's attitude to western states, recognising that there was ambiguity over whether such states were treated as representatives of tributary states or as honoured guests. I also explore the role which gift-giving, both official and unofficial, played in assessments of status and the complicated issue of diplomatic precedent, where western ambassadors attempted to assert their own concepts of status on the Ottoman system. In a further chapter I demonstrate how the English ambassador fitted into the English Court system and contrast English diplomatic ceremonial with that of the Porte. I provide an outline of the development of the conflict between the Crown, which endorsed the ambassador, and the Levant Company, which paid for him, to resolve the question of whether the embassy in Constantinople was indeed an embassy in the true sense. In this chapter I also explore the position of the few quasi-official Ottoman representatives who attended the English Court despite the official non-reciprocal diplomatic stance of the Porte. I examine the ceremonial which was provided for them and illustrate how the English system adapted to deal with this new phenomenon. This first part does not stand in isolation from the sections dealing with actual negotiations at the Porte but I intend it to place the diplomatic representatives in the framework in which they operated and establish the principles of status through which they proceeded to negotiations. In part two I consider the development of the administrative structure of the embassy in Constantinople. I include an assessment of both English and local staff, and attempt to resolve questions of the experience and efficiency of administrative personnel and of the ambassadors whom they served. I also explore the function of the embassy and establish the chains of command and channels of communication which the embassy involves. I explore the development of chancery practice during this period and give an outline of the Ottoman petition system through which all negotiations were initiated. I confront the problem of prompt authorization of documents and examine the use of a possible 'deputed Great Seal' by the embassy. The roles of Ottoman officials, especially the role of the Grand Vizier and the developing role of the Reisūlkūttab (Chief Scribe to the Divan) in foreign affairs are also discussed. Finally, in this section I consider the problems of security and communications within the region and examines the importance of the English consular network. The purpose of this section is to build up a picture of the operation of the embassy on a day to day basis to from a background to the various negotiations discussed in the final section. The final section forms the bulk of the thesis where I assess policy development in Anglo-Ottoman diplomatic relations. In the chapters of this section I explore the various types of negotiations conducted at the Porte by English ambassadors.

Full textAbstract:
Contemporary understanding of the brain indicates that a reciprocal relationship exists between mind and body. Biological functioning adjusts to the consequences of our behavior and our behavior is influenced by our biology. This is the case with the stress responsivity system. The stress hormone cortisol follows a biologically-predetermined daily cycle of secretion (controlled by circadian rhythm) that correlates with expected activity throughout the day, however this cycle can accommodate to different environmental changes that can occur. It has been noticed that individuals who report stress problems also report sleep problems. I hypothesized that sleep quality can predict maladjustments in cortisol’s rhythm. All participants provided saliva samples and had to take the Pittsburgh Sleep Quality Index (PSQI). Salivivay cortisol was measured via was enzyme-immuno-assayed for cortisol. I analyzed the data for three independent studies: (1)12 samples were taken for basal and lab days in 65 individuals. People who scored worse in total PSQI showed decreased stress reactivity (γ 21=-.02, t(63)=-2.27, p=0.026) and faster recovery (γ31=-0.102, t(608)=-2.044, p=0.041). (2)6-8 samples per day across 5 days in 120 maltreated or control adolescents. I used a 3-level hierarchical linear model to examine rhythms within each day and within each individual. The cortisol rhythm was flattened on days when adolescents had poor sleep latency (β;=.013, p=.025 for time-since-waking, β=-.0008, p=.039 for quadratic time-since-waking). (3) 10 samples were taken in 44 skydivers for jumping and basal days. Those who scored worse in sleep latency had slower reactivity (γ31=-0.16, t(284)=-3.701, p<.001) and slower recovery (γ31=0.22, t(284)=3.311, p<0.001). Stress and sleep problems are related to cognitive and physiological issues; finding an appropriate connection between them can be elemental in preventing problems.

While relationships between dreaming and certain of these processes have been identified in the literature, a comprehensive study of dreaming in relation to all of the recognized components of the sleep microstructure is completely lacking. With this in mind, the main aim of this study was to examine sleep microstructure in relation to dreaming and determine whether there is any relationship between dream recall and the various types of phasic arousal phenomena during NREM sleep, as systematised within the global framework of the cyclic alternating pattern (CAP).

Full textAbstract:
Useful knowledge discovery processes can be based on patterns extracted from large datasets. Designing efficient data mining algorithms to compute collections of relevant patterns is an active research domain. Many datasets record whether some properties hold for some objects, e. G. , whether an item is bought by a customer or whether a gene is over-expressed in a biological sample. Such datasets are binary relations and can be represented as 0/1 matrices. In such matrices, a closed itemset is a maximal rectangle of ’1’s modulo arbitrary permutations of the lines (objects) and the columns (properties). Thus, every closed itemset supports the discovery of a maximal subset of objects sharing the same maximal subset of properties. Efficiently extracting every closed itemset satisfying user-defined relevancy constraints has been extensively studied. Despite its success across many application domains, this framework often turns out to be too narrow. First of all, many datasets are n-ary relations, i. E. , 0/1 tensors. Reducing their analysis to two dimensions is ignoring potentially interesting additional dimensions, e. G. , where a customer buys an item (localized analysis) or when a gene expression is measured (kinetic analysis). The presence of noise in most real-life datasets is a second issue, which leads to the fragmentation of the patterns to discover. Generalizing the definition of a closed itemset to make it suit relations of higher arity and tolerate some noise is straightforward (maximal hyper-rectangle with an upper bound of ’0’s tolerated per hyper-plan). On the contrary, generalizing their extraction is very hard. Indeed, classical algorithms exploit a mathematical property (the Galois connection) of the closed itemsets that none of the two generalizations preserve. That is why our extractor browses the candidate pattern space in an original way that does not favor any dimension. This search can be guided by a very broad class of relevancy constraints the patterns must satisfy. In particular, this thesis studies constraints specifically designed for mining almost-persistent cliques in dynamic graphs. Our extractor is orders of magnitude faster than known competitors focusing on exact patterns in ternary relations or on noise-tolerant patterns in binary relations. Despite these results, such an exhaustive approach often cannot, in a reasonable time, tolerate as much noise as the dataset contains. In this case, complementing the extraction with a hierarchical agglomeration of the (insufficiently noise-tolerant) patterns increases the quality of the returned collection of patterns<br>Les processus de découverte de connaissances nouvelles peuvent être fondés sur des motifs locaux extraits de grands jeux de données. Concevoir des algorithmes de fouille de données efficaces pour calculer des collections de motifs pertinents est un domaine actif de recherche. Beaucoup de jeux de données enregistrent si des objets présentent ou non certaines propriétés; par exemple si un produit est acheté par un client ou si un gène est sur exprimé dans un échantillon biologique. Ces jeux de données sont des relations binaires et peuvent être représentés par des matrices 0/1. Dans de telles matrices, un ensemble fermé est un rectangle maximal de '1's modulo des permutations arbitraires des lignes (objets) et des colonnes (propriétés). Ainsi, chaque ensemble fermé sous tend la découverte d'un sous ensemble maximal d'objets partageant le même sous ensemble maximal de propriétés. L'extraction efficace de tous les ensembles fermés, satisfaisant des contraintes de pertinences définies par l'utilisateur, a été étudiée en profondeur. Malgré son succès dans de nombreux domaines applicatifs, ce cadre de travail se révèle souvent trop étroit. Tout d'abord, beaucoup de jeux de données sont des relations n-aires, c'est à dire des tenseurs 0/1. Réduire leur analyse à deux dimensions revient à ignorer des dimensions additionnelles potentiellement intéressantes; par exemple où un client achète un produit (analyse spatiale) ou quand l'expression d'un gène est mesurée (analyse cinétique). La présence de bruit dans la plupart des jeux de données réelles est un second problème qui conduit à la fragmentation des motifs à découvrir. On généralise facilement la définition d'un ensemble fermé pour la rendre applicable à des relations de plus grande arité et tolérante au bruit (hyper rectangle maximal avec une borne supérieure de '0's tolérés par hyperplan). Au contraire, généraliser leur extraction est très difficile. En effet, les algorithmes classiques exploitent une propriété mathématique (la connexion de Galois) des ensembles fermés qu'aucune des deux généralisations ne préserve. C'est pourquoi notre extracteur parcourt l'espace des motifs candidats d'une façon originale qui ne favorise aucune dimension. Cette recherche peut être guidée par une très grande classe de contraintes de pertinence que les motifs doivent satisfaire. En particulier, cette thèse étudie des contraintes spécifiquement conçues pour la fouille de quasi cliques presque persistantes dans des graphes dynamiques. Notre extracteur est plusieurs ordres de grandeurs plus efficaces que les algorithmes existants se restreignant à la fouille de motifs exacts dans des relations ternaires ou à la fouille de motifs tolérants aux erreurs dans des relations binaires. Malgré ces résultats, une telle approche exhaustive ne peut souvent pas, en un temps raisonnable, tolérer tout le bruit contenu dans le jeu de données. Dans ce cas, compléter l'extraction avec une agglomération hiérarchique des motifs (qui ne tolèrent pas suffisamment de bruit) améliore la qualité des collections de motifs renvoyées

Full textAbstract:
This dissertation explores the relations between the hippocampal theta rhythm, the activity patterns of hippocampal neurons-considered both as individuals and as populations-and memory. The main focus is a series of studies designed to gain a deeper understanding of the phenomenon of phase precession of spike activity in CA1 pyramidal cells, as first observed by O'Keefe and Recce (1993). Making use of parallel recording techniques capable of recording simultaneously from dozens of single units and up to twelve channels of EEG, it is demonstrated that: 1) The population activity of CA1 pyramidal cells is modulated by the theta rhythm, with a depth of modulation of about 50%. The peak firing of interneurons in CA1 (theta cells) occurs about 60° in advance of pyramidal cells. 2) The first spikes emitted by a CA1 pyramidal cell, as the rat enters the cell's place field, come 90°-120° after the phase of maximal pyramidal cell population activity, near the phase where inhibition is least. As shown previously by others, as the rat passes through the place field, spike activity from the cell precesses to earlier phases of the theta cycle, for a net precession that often reaches 360°. 3) Phase precession occurs both on linear tracks and in two dimensional environments where the animal does not follow regular trajectories. 4) Spikes occurring near the end of the theta cycle give less information about the animal's spatial location than spikes that occur near the beginning of the theta cycle. 5) Granule cells of the fascia dentata show maximum population activity approximately 900 phase advanced with respect to the CA1 pyramidal cell population, and are nearly silent during the last quarter of the theta cycle. 6) Granule cells show phase precession similar to that seen in CA1 pyramidal cells, with the exception that the maximum total precession is approximately 2700 rather than 360°. 7) Phase precession also appears to occur during REM sleep, but the evidence for this is not conclusive. These results are shown to imply that portions of the temporal sequence of place fields are replicated repeatedly within individual theta cycles, in highly compressed form. It is hypothesized that this permits the use of long-term potentiation for onetrial learning of the sequence, thereby giving a temporal dimension to hippocampal memory traces. The possible implications of this are discussed, as well as future experiments that may yield insight into phase precession and its functional role.

Für die Extraktion von Interaktionen entwickeln wir eine Methode zur automatischen Annotierung großer Mengen von Text im Bezug auf Relationen; diese Annotationen werden dann zur Mustererkennung verwendet, um anschließend die gefundenen Muster auf neuen Text anwenden zu können. Um Muster zu erkennen, berechnen wir Ähnlichkeiten zwischen zuvor gefundenen Sätzen, die denselben Typ von Relation/Interaktion beschreiben. Diese Ähnlichkeiten speichern wir als sogenannte `consensus patterns''. Wir entwickeln eine Alignmentstrategie, die mehrschichtige Annotationen pro Position im Muster erlaubt. In Versuchen auf bekannten Benchmarks zeigen wir empirisch, dass unser vollautomatisches Verfahren Resultate erzielt, die vergleichbar sind mit existierenden Methoden, welche umfangreiche Eingriffe von Experten voraussetzen.<br>Text mining deals with the automated annotation of texts and the extraction of facts from textual data for subsequent analysis. Such texts range from short articles and abstracts to large documents, for instance web pages and scientific articles, but also include textual descriptions in otherwise structured databases. This thesis focuses on two key problems in biomedical text mining: relationship extraction from biomedical abstracts ---in particular, protein--protein interactions---, and a pre-requisite step, named entity recognition ---again focusing on proteins. This thesis presents goals, challenges, and typical approaches for each of the main building blocks in biomedical text mining. We present out own approaches for named entity recognition of proteins and relationship extraction of protein-protein interactions. For the first, we describe two methods, one set up as a classification task, the other based on dictionary-matching. For relationship extraction, we develop a methodology to automatically annotate large amounts of unlabeled data for relations, and make use of such annotations in a pattern matching strategy. This strategy first extracts similarities between sentences that describe relations, storing them as consensus patterns. We develop a sentence alignment approach that introduces multi-layer alignment, making use of multiple annotations per word. For the task of extracting protein-protein interactions, empirical results show that our methodology performs comparable to existing approaches that require a large amount of human intervention, either for annotation of data or creation of models.

Full textAbstract:
REST (REpresentational State Transfer) is commonly used for designing APIs. Two main categories of REST API quality have been identified in previous research: linguistic and design quality. Linguistic quality revolves around the design of the URIs. Design quality revolves around the metadata and body in HTTP requests and responses. For enabling and simplifying communications with REST, both linguistic and design quality are important, however, previous research has shown that even major APIs using REST are not always following best practices for linguistic and design quality. This study investigates if there is a statistical relation between linguistic and design quality. We selected 326 API endpoints from ten public APIs for this study. This study has reused and improved a Java-based tool in previous research for detecting aspects of linguistic quality in the APIs endpoints. For this study, we also developed a tool based on Node.js for detecting aspects of design quality in the API endpoints. These two tools are applied on the same API endpoints to be able to study the statistical relation. A Chi-Square test, implemented with R, showed that there is a significant statistical relation in our findings between linguistic and design quality. Pairwise phi-coefficient comparisons, implemented with Python, between each combination of the linguistic and design aspects used in this study identified eight weak and two moderate relations among the linguistic and design quality aspects. However, sample tests showed that the Java-based tool for detecting linguistic quality were not accurate, which made us fail to answer our problem formulation.
