Full textAbstract:
A schema is described as a diagram showing the basic outline of something, or as an organizational or conceptual pattern in the mind. It is also, in Kantian philosophy, a method that allows the understanding to apply concepts to the evidence of the senses. My Schema is a model of emergence.

Thesis (MSc)--Stellenbosch University, 2001.ENGLISH ABSTRACT: In response to increased focus on schemas within cognitive therapy and specifically in the treatment of personality disorders, Young developed an instrument to measure early maladaptive schemas, the Young Schema Questionnaire (YSQ). The statistical properties of this measure have been investigated, and due to its length, a shortened version was developed (the YSQ-S). In the present study the factor structure of the YSQ-S was investigated in a group of South African undergraduate psychology students (N = 300). In contrast with the findings of the studies done on the YSQ, 14 of Young's 15 schemas were identified as factors in the YSQ-S, corresponding largely with the theoretically underlying structure. A higher order factor analysis solution was also found to resemble the structure proposed by Young.
AFRIKAANSE OPSOMMING: Die groter fokus op skemas binne die kognitiewe terapie, veral met betrekking tot die behandeling van persoonlikheidsversteurings, het daartoe gelei dat Young 'n meetmiddel, naamlik die Young Schema Questionnaire (YSQ), ontwikkel het om vroeë wanaangepaste skemas ("early maladaptive schemas") te meet. Die statistiese eienskappe van hierdie meetmiddel is reeds nagevors, en as gevolg van die lengte van hierdie meetmiddel, is 'n verkorte weergawe daarvan ontwikkel (YSQ-S). In die huidige studie is die faktoriale struktuur van die YSQ-S by 'n groep Suid Afrikaanse voorgraadse sielkunde studente (N = 300) ondersoek. In teenstelling met die bevindings van vroeëre studies op die YSQ, is 14 van die 15 van Young se skemas as faktore by die YSQ-S geïdentifiseer, wat grootliks ooreengestem het met die teoreties gekonseptualiseerde onderligende struktuur. Die oplossing van 'n hoër-ordefaktorontleding het ook ooreengestem met die struktuur wat deur Young voorgestel is.

Full textAbstract:
Schema therapy is a leading contemporary approach to treating mental illness. The therapy integrally uses self-report measures of negative schemas (“long lasting patterns of emotions, cognitions and memories”), and the negative parenting patterns that are linked to the development of these schemas. However, the negative parenting measures are insufficient, and there are no corresponding measures of positive schemas or positive parenting patterns. Study 1 focused on the development of a measure for positive schemas, the Young Positive Schema Questionnaire (YPSQ). Study 2 focused on the development of a measure for positive parenting patterns, the Positive Parenting Schema Inventory (PPSI). Finally, Study 3 empirically showed that the subscales of the Young Parenting Inventory (YPI) were not robust, and it provided a revised alternative (YPI-R2). For all three studies combined, community samples (n = 204 to 628) were collected from five countries in Asia (India, Indonesia, Malaysia, Singapore, and the Philippines) as well as the United States. The factor structure of the three instruments (the YPSQ, PPSI and YPI-R2) was stable in both Eastern and Western samples (in multigroup confirmatory factor analysis). All three scales showed prediction of mental health over and above what was possible with previous measures (incremental validity). The scales were not simply proxies for previously measured constructs (divergent validity). These scales also demonstrated significant associations with other established measures of parenting (construct validity). They also showed associations with negative schemas, well-being and ill-being (convergent validity). This thesis provides the tools needed to include a focus on positive as well as negative schemas and parenting patterns in both research and clinical practice. It also shows the benefits of so doing.

Nowadays there are many CAD system used in garment industry, but only few systems are used to compose measurement schemas. Only the biggest companies like well known “Gerber technology”, “Lectra system”, “Richpeace” could offer such kind of systems. Unfortunately, these systems are quite complicated, expensive and could only be used with the CAD system from the same creators. This is the reason why many companies are not capable of buying a full CAD system besides there are no possibilities to buy a system to compose garment products measurement schemas separately. So, naturally, there comes a demand for a less complicated and cheaper system. The main objective of this project was to create less complicated garment products measurement schemas composing system, which includes features of a large system and also avoids its defects.
An analysis of existing garment products’ measurement schemas software and customers’ needs was made in this work. “Clothing models measuring scheme composition system” software was created as an outcome of this work. The project was programmed with JAVA programming language. Therefore it can be used on the different operating systems. The system was successfully installed and tested in the UAB “Vivat Modus” company. In short period of time this company has seen the great propose of system. People who were using the new system to create garment products’ measurement schemas have saved their time and made less mistakes. The system helped to save... [to full text]

Full textAbstract:
Schema therapy was developed by Jeffery Young to treat adults with personality disorders, and has been evidenced to be effective in treating both Axis I and Axis II disorders. While Young stipulates that schemas are likely to be in place by adolescence, there is currently little agreement over the appropriateness of schema theory and therapy in understanding and treating psychopathology in adolescence. This thesis aims to explore the evidence–base and potential utility of applying schema theory to adolescent psychopathology, and consists of a systematic review and research article. The review included published studies measuring Early Maladaptive Schemas (EMS) in 12 to 18 year olds, including those exploring relationships between EMS and psychopathology. The search of relevant literature from 1990 to 2012 yielded 19 articles for review, which were then subject to assessment of methodological quality. Most studies were assessed as ‘moderate’ in quality. Good quality evidence was found for the detection of higher rates of EMS in clinical or referred adolescent populations compared to non–clinical populations, as well as some evidence for effects of age and gender on EMS. Less consistent evidence was found for specific associations between individual EMS or domains and particular types of psychopathology or problem behaviour. Common limitations of the articles reviewed included poor control of confounding variables and little testing of EMS alongside contextual constructs to provide validation of findings. The main research article used a quantitative, questionnaire–based cross– sectional design to test the dimensionality of the schema concept in a population of 12 to 18 year–olds, comparing levels of EMS between a referred and non–referred group. EMS were measured alongside attachment and interpersonal behaviours to test their unique predictive effect on psychopathology. Specific relationships between individual groups of EMS and type of psychopathology were also explored. Results showed that the referred group scored significantly higher than the non–referred group on overall schema score. Schemas were found to significantly predict level of psychopathology, over and above prediction by attachment or interpersonal behaviour scores. There was also evidence for the specific prediction of internalising and externalising problem behaviour, affective, anxiety, oppositional–defiant and conduct problems by clusters of EMS. In conclusion, EMS appear to be a valid concept in predicting and understanding psychopathology in adolescence. A conceptual model is suggested for future research to explore the adaptation of schema theory more fully within developmental psychopathology. It is hoped that future research will test other aspects of schema theory in adolescents such as coping styles and modes. It is proposed that, following further validating evidence, this may result in the development of improved interventions for a range of presenting problems in adolescence.

Full textAbstract:
We all have a body : our own body and just one body. Through it, we move, we interact with the world and other persons, we perceive, basically we live. It's a unique essential object. If it is true that we have only one physical body, we also have many representations of it in the brain. There is little agreement about the exact number of body representations in the brain, but not on the fact that we have more than one. The multi-componential models of body representation are based on the notion, supported by scientific evidence that different activities demand and rely on specifically adapted representations. In my thesis, I studied one particular body representation that is used and involved in action planning and execution, i.e. the Body Schema. I have been able to describe and measure the plasticity of the Body Schema and its level of specificity in healthy individuals. In particular, using a tool-use paradigm, I showed that the Body Schema is quickly and efficiently updated once a change in the body configuration occurs. With a series of kinematic studies, I contributed unveiling the ingredients that rule the plasticity of the BS and the sensory information that is used to this purpose. As a result of my thesis, I suggest that a clearer definition and operational description of the Body Schema, as an action-devoted repertoire of effectors representations, is possible, particularly thanks to its plastic features

Full textAbstract:
This work examines Schema-based Reasoning (SBR) (Turner 1994), a general-purpose problem solver that provides context-centric mediation ofsolutions in open domains~ This thesis will argue that Turner's SBR requires augmentation in commercial and critical applications, in order to obtain a principled adherence to domain-specific, behavioural constraints. An approach is required that balances the preservation ofdomain-specific solution trajectories and context-mediated, opportunistic problem solving found within Turner's SBR. The Directed-SBR model is proposed as the augmentation ofTurner's SBR, with principled extensions that enforce an adherence to such behavioural constraints. The principles augment Turner's SBR by enforcing a further mediation ofthe context-centric p~blem solving, drawing upon a problem domain's viability constraints during solution selection. Furthermore, a problem domain's behavioural constraints are brought into focus as a central consideration during knowledge engineering. This provides focus upon specific domain states, the extraction ofappropriate information from domain ~esources, and at the most appropriate times. The resultant Directed-SBR model establishes a balance between the selection ofthe most appropriate solutions, given the nte~tions ofthe problem solving, while preserving the tasks already unde$ken. be investigation into the adequacies ofTurner's SBRmodel adopts combinatorial pproaches ofquantitative and qualitative research methods. It demonstrates that 'irected-SBR enables the academic and commercial domains examined to be reinforced ith solution mediation that considers domain integrity, in combination with mtext-mediation. Significantly, Directed-SBR has been tested and evaluated in a large ale, distributed, commercial domain, and is operational in a production environment, :ling problem diagnosis, system testing and autonomous support tasks.

Zainol, Zurinahni. "XML documents schema design." Thesis, University of Hull, 2012. http://hydra.hull.ac.uk/resources/hull:8315.
Full textAbstract:
The eXtensible Markup Language (XML) is fast emerging as the dominant standard for storing, describing and interchanging data among various systems and databases on the intemet. It offers schema such as Document Type Definition (DTD) or XML Schema Definition (XSD) for defining the syntax and structure of XML documents. To enable efficient usage of XML documents in any application in large scale electronic environment, it is necessary to avoid data redundancies and update anomalies. Redundancy and anomalies in XML documents can lead not only to higher data storage cost but also to increased costs for data transfer and data manipulation. To overcome this problem, this thesis proposes to establish a formal framework of XML document schema design. To achieve this aim, we propose a method to improve and simplify XML schema design by incorporating a conceptual model of the DTD with a theory of database normalization. A conceptual diagram, Graph-Document Type Definition (G-DTD) is proposed to describe the structure of XML documents at the schema level. For G- DTD itself, we define a structure which incorporates attributes, simple elements, complex elements, and relationship types among them. Furthermore, semantic constraints are also precisely defined in order to capture semantic meanings among the defined XML objects. In addition, to provide a guideline to a well-designed schema for XML documents, we propose a set of normal forms for G-DTD on the basis of rules proposed by Arenas and Libkin and Lv. et al. The corresponding normalization rules to transform from a G- DTD into a normal form schema are also discussed. A case study is given to illustrate the applicability of the concept. As a result, we found that the new normal forms are more concise and practical, in particular as they allow the user to find an 'optimal' structure of XML elements/attributes at the schema level. To prove that our approach is applicable for the database designer, we develop a prototype of XML document schema design using a Z formal specification language. Finally, using the same case study, this formal specification is tested to check for correctness and consistency of the specification. Thus, this gives a confidence that our prototype can be implemented successfully to generate an automatic XML schema design.

Full textAbstract:
The traditional view of systems memory consolidation is that it is a gradual process that takes place over days or weeks. Within this approach, the hippocampus (HPC) is thought to be involved in the rapid encoding of specific events, whilst neocortex is thought to be involved in slow learning. An idea posited recently is that systems consolidation can occur rapidly if an appropriate “schema” into which the new information can be incorporated has been previously created. Using a hippocampaldependent paradigm, rats were trained to learn a schema involving 6 flavour-place paired-associates (PAs). Once the schema was acquired, relevant new information then became assimilated into extra-hippocampal regions and rapidly became hippocampal-independent. Building upon this foundation and the PAs schema paradigm, this thesis has explored several aspects of the neurobiology of schemas in animals. The first part of the thesis examined the importance of a relevant schema in new information processing. Rats were trained in both a consistent and inconsistent schema. In the consistent schema, rats could learn new PAs in a single trial; however, in the inconsistent schema, rats failed to learn the new PAs as they had not established an appropriate schema that could facilitate rapid learning. The second part of the thesis investigated the role of hippocampal NMDA receptors and dopamine receptors during encoding of new PAs. Bilateral hippocampal infusion of either the NMDA receptor antagonist D-AP5 or the D1/D5 dopamine receptor antagonist SCH23390 before encoding of new PAs resulted in impaired memory tested at 24 hr. This result suggests that the encoding of new PAs is dependent upon NMDA receptors in the HPC and also that dopamine is involved in the modulation of encoding new PAs. The final chapters of the thesis attempted to identify the extrahippocampal regions in which these new PAs are integrated with the schema during encoding. To identify the regions that may be involved, immediate early genes (Zif268 and Arc) were used. In a group of cortical structures, including the prelimbic cortex, there was significantly higher Zif268 and Arc expression when encoding 2 new PAs compared to the reactivation of previously learned (original) PAs or the encoding of 6 new PAs. These findings indicate that the prelimbic cortex may be critical for rapid assimilation of new information into a pre-existing schema. Finally, the last experiment in the thesis investigated this finding using bilateral microinfusions of either the AMPA receptor antagonist CNQX or the NMDA receptor antagonist D-AP5 into the prelimbic cortex. Infusions of CNQX and D-AP5 resulted in poor learning of the new PAs in the schema task. This indicates that parallel encoding of new PAs occurred in the prelimbic cortex and the HPC. The experimental results presented in this thesis suggest that the prelimbic cortex, in particular, plays a crucial role along with the HPC during encoding of new information in rapid memory formation.

Com o advento da Web, a construção de mediadores impõe desafios importantes, tais como a capacidade de fornecer acesso integrado a fontes de dados independentes e dinâmicas e a habilidade de resolver a heterogeneidade semântica entre os esquemas destas fontes. Para lidar com esses desafios, o alinhamento de esquemas é uma questão fundamental. Nesta tese são propostas abordagens de alinhamento de esquemas de classificação (tesauros) e esquemas conceituais, utilizando instâncias como evidências para os mapeamentos. As abordagens propostas são classificadas em dois tipos: adaptativa e a priori, referindo-se, respectivamente, à descoberta dos mapeamentos de forma incremental ou à definição dos mapeamentos antes da implantação do mediador. Por fim, são apresentados experimentos para validação e teste das abordagens propostas.

With the advent of the Web, the design of mediators imposes important challenges, such as the ability of providing integrated access to independent and dynamic data sources and the ability of resolving the semantic heterogeneity between different data source schemas.

The proposed approaches are classified as adaptative and a priori, referring to, respectively, the discovery of the mappings in an incremental way or the definition of the mappings before the deployment of the mediator. Finally, experiments to validate and test the proposed approaches are presented.

Full textAbstract:
Schema mappings have been extensively studied in the context of data exchange and data integration, where they have turned out to be the right level of abstraction for formalizing data interoperability tasks. Up to now and for the most part, schema mappings have been studied as static objects, in the sense that each time the focus has been on a single schema mapping of interest or, in the case of composition, on a pair of schema mappings of interest. In this paper, we adopt a dynamic viewpoint and embark on a study of sequences of schema mappings and of the limiting behavior of such sequences. To this effect, we first introduce a natural notion of distance on sets of finite target instances that expresses how "Close" two sets of target instances are as regards the certain answers of conjunctive queries on these sets. Using this notion of distance, we investigate pointwise limits and uniform limits of sequences of schema mappings, as well as the companion notions of pointwise Cauchy and uniformly Cauchy sequences of schema mappings. We obtain a number of results about the limits of sequences of GAV schema mappings and the limits of sequences of LAV schema mappings that reveal striking differences between these two classes of schema mappings. We also consider the completion of the metric space of sets of target instances and obtain concrete representations of limits of sequences of schema mappings in terms of generalized schema mappings, that is, schema mappings with infinite target instances as solutions to (finite) source instances.

Full textAbstract:
Schema integration is the task of integrating several local schemata into one global database schema. It is a complex, error-prone and time consuming task. Problems arise in recognizing and resolving problems, such as differences and similarities, between two schemata. Problems also arise in integrating static and dynamic schemata. In this thesis, three research topics are addressed: Maintaining Vocabulary in Schema Integration, Integration of Static Schemata and Integration of Static and Dynamic Schemata, while applying the notation in the Enterprise Modeling approach. In Maintaining Vocabulary in Schema Integration an analysis of what semantic loss is and why it occurs in schema integration is conducted. Semantic loss is a problem that should be avoided because both concepts and dependencies might be lost. In the thesis, it is argued that concepts and dependencies should be retained as long as possible in the schemata. This should facilitate user involvement since the users’ vocabulary is retained even after resolving similarities and differences between two schemata. In Integration of Static Schemata two methods are developed. These methods facilitate recognition and resolution of similarities and differences between two conceptual database schemata. By applying the first method, problems between two schemata can be recognized that otherwise could pass unnoticed; by applying the second method, problems can be resolved without causing semantic loss by retaining concepts and dependencies in the schemata. In Integration of Static and Dynamic Schemata a method on how to integrate static and dynamic schemata is developed. In the method, focus is put on pre- and post-conditions and how to map these to states and state changes in the database. By applying the method, states that are important for the database can be designed and integrated into the conceptual database schema. Also, by applying the method, active database rules can be designed and integrated into the conceptual database schema.

Full textAbstract:
Drawing from the meta-construct model of cognition (Ingram, 1984; Ingram & Kendall, 1986), the goal of the present study was to examine whether the structural (i.e., self-complexity; SC, Linville, 1985) and propositional components of schemas (dysfunctional attitudes; DAS, Weissman & Beck, 1978), independently and in interaction with each other and stressors, lead to changes in depressive symptoms. The prediction was that if negative self-attributes across different self-aspects in a specific domain, interpersonal or achievement, are highly distinct (i.e., high negative SC) or if positive self-attributes across different aspects of self are redundant (i.e., low positive SC), then the DAS would be more likely to lead to higher levels of depression when domain-congruent stressors occur. To test the main effect, two-way interaction, and three-way interaction hypotheses, the present study used a two month longitudinal design involving three assessment periods, separated by one month. At the baseline, a total of 189 students participated in the study. Of these students, 163 and 121 students participated in the first and second follow-ups, respectively. Multiple hierarchical regression analyses were used to examine two-way and three-way interactions. Results showed strong support for the predictive power of negative SC with respect to depressive symptomatology. The DAS, on the contrary, was a concurrent factor related to depressive symptoms. Further, the present study did not provide supportive evidence for the diathesis-stress model of depression. Although contradicting expectations, the pattern of relationships between interpersonal negative SC, DAS, distal stressors suggested promising venues for future research.Ph. D.

Full textAbstract:
Modern agile software development methods allow to continuously evolve software systems by easily adding new features, fixing bugs, and adapting the software to changing requirements and conditions while it is continuously used by the users. A major obstacle in the agile evolution is the underlying database that persists the software system’s data from day one on. Hence, evolving the database schema requires to evolve the existing data accordingly—at this point, the currently established solutions are very expensive and error-prone and far from agile.
In this thesis, we present InVerDa, a multi-schema-version database system to facilitate agile database development. Multi-schema-version database systems provide multiple schema versions within the same database, where each schema version itself behaves like a regular single-schema database. Creating new schema versions is very simple to provide the desired agility for database development. All created schema versions can co-exist and write operations are immediately propagated between schema versions with a best-effort strategy. Developers do not have to implement the propagation logic of data accesses between schema versions by hand, but InVerDa automatically generates it.
To facilitate multi-schema-version database systems, we equip developers with a relational complete and bidirectional database evolution language (BiDEL) that allows to easily evolve existing schema versions to new ones. BiDEL allows to express the evolution of both the schema and the data both forwards and backwards in intuitive and consistent operations; the BiDEL evolution scripts are orders of magnitude shorter than implementing the same behavior with standard SQL and are even less likely to be erroneous, since they describe a developer’s intention of the evolution exclusively on the level of tables without further technical details. Having the developers’ intentions explicitly given in the BiDEL scripts further allows to create a new schema version by merging already existing ones.
Having multiple co-existing schema versions in one database raises the need for a sophisticated physical materialization. Multi-schema-version database systems provide full data independence, hence the database administrator can choose a feasible materialization, whereby the multi-schema-version database system internally ensures that no data is lost. The search space of possible materializations can grow exponentially with the number of schema versions. Therefore, we present an adviser that releases the database administrator from diving into the complex performance characteristics of multi-schema-version database systems and merely proposes an optimized materialization for a given workload within seconds. Optimized materializations have shown to improve the performance for a given workload by orders of magnitude.
We formally guarantee data independence for multi-schema-version database systems. To this end, we show that every single schema version behaves like a regular single-schema database independent of the chosen physical materialization. This important guarantee allows to easily evolve and access the database in agile software development—all the important features of relational databases, such as transaction guarantees, are preserved. To the best of our knowledge, we are the first to realize such a multi-schema-version database system that allows agile evolution of production databases with full support of co-existing schema versions and formally guaranteed data independence.

Integração de dados refere-se ao problema de combinar dados que estão armazenados em diferentes fontes, fornecendo ao usuário uma visão unificada dos dados. As consultas são então expressas em um esquema global ou esquema mediado, que deve incluir restrições de integridade que contribuam para um entendimento correto sobre o que a semântica das fontes de dados do ambiente de mediação tem em comum. Esta tese endereça o problema de modelar as restrições de um esquema mediado a partir das restrições dos esquemas importados e dos mapeamentos de esquemas. Argumenta-se que as restrições devem ser modeladas como o ínfimo das restrições dos esquemas exportados, depois de traduzidos para um vocabulário comum. Desta forma, assegura-se que os usuários do esquema mediado interpretarão os resultados das consultas corretamente. Para uma família expressiva de restrições, esta tese mostra como computar eficientemente o ínfimo de conjuntos de restrições.
Data integration refers to the problem of combining data stored in different sources, providing users with a unified view of the data. Queries are then expressed in terms of a global or mediated schema, which should include integrity constraints that contribute to a correct understanding of what the semantics of the data sources have in common. This thesis addresses the problem of modeling the constraints of a mediated schema from the imported schemas constraints and mappings. It argues that the constraints should be modeled as the greatest lower bound of the constraints of the export schemas, after appropriate translation to a common vocabulary. This assures that users of the mediated schema will correctly interpret query results. For a rich family of constraints, it shows how to efficiently compute the greatest lower bound of sets of constraints.

Trois cas cliniques servent d'introduction a la these: trois cas d'etiologie differente, de gravite diverse, traites avec un inegal succes, mais qui se ressemblent en ceci, qu'ils auraient evolue autrement, s'ils n'avaient ete abordes sous cette approche specifique du schema corporel en sophrologie. La premiere partie de la these est consacree a l'analyse histori co-critique du concept de schema corporel, dont il ressort: - que celui-ci a emerge des failles de la medecine officielle, et notamment de la neuro-physiologie; - que rien de veritablement nouveau n'est intervenu a cet egard depuis le debut du siecle, la psychanalyse et la psychosomatique en particulier ayant en quelque sorte fait l'impasse sur le su- jet, malgre des efforts de synthese, dont celui de schilder reste le plus signifiant. Caycedo, l'inventeur de la sopphrologie, ne sera pas pour autant un theoricien du schema corporel. Nous le voyons emprunter a des sour- ces diverses: training autogene de schultz, phenomenologie, techni- ques orientales d'entrainement corporel. .Three clinic cases serve as an introduction to the thesis: three cases of different origin, and of various degrees of gravity, treated with different degrees of success, but which are alike in that they would have developed differently, if they hadn't been tackled with this specific approach-the bodyschema in sophrology. The first part of the thesis is devoted to a historico-critical analysis of the bodyschema concept, from which it emerges that: - this concept stems from flaws in official medical science, notably in the field of neuro-physiology; - nothing really new has occurred in this respect since the begin- ning of the century. Psychoanalysis and psychosomatic research in particular, have to a certain degree failed to deal with the subject, despite some work on synthesis, of which schilder's contri- bution remains the most significant. Caycedo, the inventor of sophrology, cannot however be considered a bodyschema theorist. We see him borrowing from various sources such as schultz's autotraining, phenomenology and oriental techniques. In fact, it is from the very practice of sophrology that we are able

Tommy Wahlgren (2010). Elevernas syn på sitt schemaSkolutveckling och ledarskap, SÄL III:4, Lärarutbildningen, Malmö högskola.Jag har i detta arbeta undersökt hur en grupp elever på byggprogrammet vid en kommunal gymnasieskola uppfattar sitt skolschema, och hur de tror att schemat påverkar deras studieresultat. I skolan utgör schemat det skriftliga dokument som beskriver hur skolan har valt att organisera sin undervisning. Schemat är det viktigaste instrumentet skolan har för att organisera undervisningen efter läroplanens intentioner och krav. För att få svar på mina frågor, har jag genomfört en kvantitativ undersökning. Undersökningen har genomförts med hjälp av en frågeenkät bland 74 elever, som går det avslutande året på byggprogrammet vid en kommunal gymnasieskola.Resultatet av studien visar att en klar majoritet av eleverna tycker att de har ett bra schema, och att 14-dagarsschemat passar bäst för karaktärsämnesperioderna. Undersökningen visar ingen klar bild över hur schemat påverkar elevernas studier dessutom har eleverna svårt att tolka hur mycket schemat påverkar deras studieresultat. Det finns inte heller något entydigt önskemål om någon annan schematyp än 14-dagarsschemat.En av mina slutsatser är att eleverna tycker 14-dagarsschemat är bra att använda sig av när man organiserar undervisningen på byggprogrammet på den aktuella skolan. Däremot var det få elever som visste om schemat påverkade studieresultatet, eller vilket schema de ville ha istället för sitt nuvarande 14-dagarsschema.

O objetivo do presente trabalho é investigar os efeitos de duas atividades de pré-leitura, "Possible Sentences" (Moore and Arthur, 1981) e uma versão modificada da "Request Procedure" (Manzo, 1969), na compreensão em leitura de alunos brasileiros estudando uma segunda língua no Brasil. Quarenta alunos de nível intermediário matriculados em Inglês numa escola particular em Florianópolis, no estado de Santa Catarina, participaram do estudo. Os sujeitos leram quatro textos, cada um trabalhado de maneira diferente, três precedidos de atividades de pré-leitura i.e., 1) Possible Sentences, 2) Request Procedure, 3) Possible Sentence + Request Procedure e um texto sem atividade, como controle. Imediatamente após terem lido cada texto, os sujeitos foram testados através de 5 perguntas de compreensão e 10 itens do tipo verdadeiro ou falso. Os sujeitos também avaliaram os textos em termos de dificuldade e familiaridade com o conteúdo dos mesmos. De acordo com a ANOVA (Análise de Variância) realizada nos resultados totais (soma do resultado das perguntas e dos itens verdadeiro/falso), os tratamentos tiveram efeito significativo na compreensão dos sujeitos, i.e., quando leram os textos precedidos de uma das três atividades obtiveram melhores resultados nos testes do que quando leram sem atividades. Resultados semelhantes foram encontrados para a ANOVA realizada nos dados obtidos nas perguntas. Entretanto não foram encontrados efeitos estatísticamente significativos nos resultados dos itens verdadeiro/falso. O teste de "Tukey" para comparações múltiplas não revelou diferenças significativas entre as próprias atividades de pré-leitura. Nenhuma correlação foi encontrada entre a avaliação dos sujeitos em relação ao nível de familiaridade com o conteúdo dos textos e os resultados obtidos pelos mesmos nas perguntas de compreensão. Também não foi encontrado correlação entre o nível de familiaridade e os resultados dos testes do tipo verdadeiro/falso. Entretanto, houve uma correlação moderada entre a avaliação dos textos como fáceis/difíceis e os resultados obtidos das perguntas, mas novamente não foi encontrada correlação entre esta avaliação e os resultados obtidos nos itens verdadeiro/falso. Todos os resultados foram analisados do ponto de vista da teoria dos esquemas da compreensão em leituras.

Full textAbstract:
The present study aimed (1) to examine possible influence of demographic variables of age, gender, familial monthly income, relationship status, mother&rsquos education, father&rsquo
s education on Parenting Styles, Schema Domains, Schema Coping Styles, and Psychopathology/Life Satisfaction
(2) to examine associated factors of Schema Domains, Schema Coping Styles, Psychopathology/Life Satisfaction
(3) to examine the mediator role of Schema Domains in the relationship between Parenting Styles and Psychopathology/Life Satisfaction
(4) to examine the mediator role of Schema Coping Styles in the relationship between Schema Domains and Psychopathology/Life Satisfaction. In order to fulfill these aims 404 people between the ages 18-42 participated in the study. According to results, negative parenting practices from both sources (i.e., mother, father) were found to be associated with stronger levels of schema domains. Furthermore, Impaired Limits/Exaggerated Standards and Impaired Autonomy/Other Directedness schema domains were found to be associated with Compensation schema coping style
while Disconnection/Rejection and Impaired Limits/Exaggerated Standards schema domains were found related to Avoidance schema coping style. After that, mother&rsquo
s parenting style, schema domains of Disconnection/Rejection, and Impaired Autonomy/Other Directedness were found to be significantly associated with depressive symptomatology. In addition, psychopathological symptoms were found to be associated with both parenting styles, schema domains of Disconnection/Rejection and Impaired Limits/Exaggerated Standards, and schema coping style of Avoidance. What is more, both parenting styles, schema domain of Disconnection/Rejection, were negatively
and compensation schema coping style was positively associated with satisfaction with life. As for the mediational analyses, schema domains mediated the relationship between parenting styles and psychopathology/life satisfaction
furthermore, schema coping styles mediated the relationship between schema domains and psychopathology/life satisfaction.

Program-understanding schemata for understanding the static properties of C++ programs are presented. For understanding purposes, we have selected seven key concepts of the C++ programming language. A C++ program is viewed as being composed of these seven key concepts and the relationships which may exist between them. These seven key C++ concepts and their relationships are represented using concept templates. The information grouped within these concepts is shown using twenty-six display templates. A representation schema and a navigation schema for the concept templates and the display templates are explained in detail.

Full textAbstract:
This thesis presents a solution for an XML Schema mapping problem. Furthermore, this thesis shows how this solution can be used in a practical way.
The research presented in this thesis is based on a novel approach for the internal representation of the XML Schema during the matching process. This internal representation uses the XML Schema Infoset Model. The majority of XML schema matching tools use a graph representation for XML schemas. This representation leads to limitations regarding XML Schema documents complexity and scalability of the matching tool.
An important feature that was also implemented is the mapping refinement by a user at the end of the automatic matching process. Two XML schemas can be mapped in different ways and these mappings can be stored in a repository. A domain expert can then decide which mapping is best suited for the two XML schemas.

"Archiv" ist bei Foucault der Titel für eine historische Größe der Wissensgeschichte, die unter bestimmten Bedingungen der Sagbarkeit
zustande kommt und diese zugleich wirksam macht: "Das Archiv ist zunächst das Gesetz dessen, was gesagt werden kann, das System, das das Erscheinen der Aussagen als einzelner Ereignisse beherrscht. Aber das Archiv ist auch das, was bewirkt, daß all diese gesagten Dinge sich nicht bis ins Unendliche in einer amorphen Vielfalt anhäufen, sich auch nicht in eine bruchlose Linearität einschreiben und nicht allein schon bei zufälligen äußeren Umständen verschwinden; sondern daß sie sich in distinkten Figuren anordnen, sich aufgrund vielfältiger Beziehungen miteinander verbinden, gemäß spezifischen Regelmäßigkeiten sich behaupten ( ... )." Archiv in diesem Sinn ist so etwas wie ein Ermöglichungsgrund von Diskursivität, eine Instanz der historischen Analyse, die das Gesagte in seiner Existenz verständlich macht. In dieser Beziehung soll der Begriff im folgenden auf eine Bibliothek bezogen werden, die wie keine andere das Wissen das 17. Jahrhunderts repräsentiert. So kann man jedenfalls sprechen, wenn man im Hinblick auf die in Wolfenbüttel vollendete Büchersammlung blickt, die nicht nur die zweit- oder drittgrößte Bibliothek war, als ihr Gründer, Herzog August, 1666 starb, sondern die mit größter Wahrscheinlichkeit umfangreichste jemals von einem einzelnen Menschen mit größter Sorgfalt zusammengetragene Bibliothek überhaupt ist.
