Universities are an ideal environment to assist students in the development of their leadership skills in a safe and supportive environment. The development of emotional intelligence (EI) has become an important aspect of student leadership development. The purpose of the study was to examine the emotionally intelligent leadership (EIL) scores of students working in a collegiate recreation setting and to examine their perceptions of their own EI and EIL. An exploratory, sequential, mixed-methods approach was used to explore the EIL scores of students employed in collegiate recreation departments at seven university sites. EIL was the theoretical framework used in this study (Shankman et al., 2015).
The findings of this study showed no statistically significant difference in mean scores of EIL between students working in formal and informal leadership positions or between genders. Themes that emerged from the participant’s perceptions of their own EI and EIL were communication, confidence, perceived leadership ability, and teamwork.
Understanding how students perceive their own EI and EIL can assist practitioners in the creation and development of intentional training and development programs.

OWL 2 EL is a popular ontology language that is based on the EL family of description logics and supports regular role inclusions,axioms that can capture compositional properties of roles such as role transitivity and reflexivity. In this thesis, we present several novel complexity results and algorithms for answering expressive queries over OWL 2 EL knowledge bases (KBs) with regular role inclusions. We first focus on the complexity of conjunctive query (CQ) answering in OWL 2 EL and show that the problem is PSpace-complete in combined complexity, the complexity measured in the total size of the input. All the previously known approaches encode the regular role inclusions using finite automata that can be worst-case exponential in size, and thus are not optimal. In our PSpace procedure, we address this problem by using a novel, succinct encoding of regular role inclusions based on pushdown automata with a bounded stack. Moreover, we strengthen the known PSpace lower complexity bound and show that the problem is PSpace-hard even if we consider only the regular role inclusions as part of the input and the query is acyclic; thus, our algorithm is optimal in knowledge base complexity, the complexity measured in the size of the KB, as well as for acyclic queries. We then study graph queries for OWL 2 EL and show that answering positive, converse- free conjunctive graph queries is PSpace-complete. Thus, from a theoretical perspective, we can add navigational features to CQs over OWL 2 EL without an increase in complexity. Finally, we present a practicable algorithm for answering CQs over OWL 2 EL KBs with only transitive and reflexive composite roles. None of the previously known approaches target transitive and reflexive roles specifically, and so they all run in PSpace and do not provide a tight upper complexity bound. In contrast, our algorithm is optimal: it runs in NP in combined complexity and in PTime in KB complexity. We also show that answering CQs is NP-hard in combined complexity if the query is acyclic and the KB contains one transitive role, one reflexive role, or nominalsâconcepts containing precisely one individual.

Description logics (DLs) are knowledge representation formalisms with numerous applications and well-understood model-theoretic semantics and computational properties. SRIQ is a DL that provides the logical underpinning for the semantic web language OWL 2, which is the W3C standard for knowledge representation on the web. A central component of most DL applications is an efficient and scalable reasoner, which provides services such as consistency testing and classification. Despite major advances in DL reasoning algorithms over the last decade, however, ontologies are still encountered in practice that cannot be handled by existing DL reasoners. Consequence-based calculi are a family of reasoning techniques for DLs. Such calculi have proved very effective in practice and enjoy a number of desirable theoretical properties. Up to now, however, they were proposed for either Horn DLs (which do not support disjunctive reasoning), or for DLs without cardinality constraints. In this thesis we present a novel consequence-based algorithm for TBox reasoning in SRIQ - a DL that supports both disjunctions and cardinality constraints. Combining the two features is non-trivial since the intermediate consequences that need to be derived during reasoning cannot be captured using DLs themselves. Furthermore, cardinality constraints require reasoning over equality, which we handle using the framework of ordered paramodulation - a state-of-the-art method for equational theorem proving. We thus obtain a calculus that can handle an expressive DL, while still enjoying all the favourable properties of existing consequence-based algorithms, namely optimal worst-case complexity, one-pass classification, and pay-as-you-go behaviour. To evaluate the practicability of our calculus, we implemented it in Sequoia - a new DL reasoning system. Empirical results show substantial robustness improvements over well-established algorithms and implementations, and performance competitive with closely related work.

Повний текст джерелаАнотація:
The role of TAs has changed considerably from that of supporting teachers and children with additional learning needs to that of providing emotional support and personal and social development (Groom, 2006). Consequently, the Emotional Literacy Support Assistant (ELSA) programme was developed (Burton, 2009) as a training programme to develop the skills of teaching assistants (TAs) in schools to provide emotional support for children in their schools. However, their effectiveness in delivering this programme is likely to be governed by levels of self-efficacy, that is, the belief they have about their capabilities (Gibbs, 2002; Tschannen-Moran, Woolfolk-Hoy & Hoy, 1998). Self-efficacy beliefs are predicted by the components of trait-emotional intelligence (Chan, 2004) and there is a need for research exploring the relationship between school staff emotions and efficacy beliefs (Emmer & Hickman, 1991). This research utilises a multi-methods approach exploring the self-efficacy and trait-emotional intelligence of TAs before and after having completed the ELSA training and the perceptions TAs have regarding their future role. Statistical analysis of the quantitative data collected from the questionnaires revealed that the self-efficacy and trait-emotional intelligence scores of the participants increased after having completed the ELSA training. Thematic analysis of the qualitative data collected from the focus group revealed that TAs identified issues that influenced their perceptions of their future roles as ELSA both negatively and positively. The four main themes were identified, with sub themes and subordinate themes. The overarching main theme identified was ‘systemic issues’ as the main concern with the sub themes ‘lack of support from school’ and ‘lack of self-efficacy for the role’. The second occurring main theme was ‘improved knowledge and understanding’ with the sub themes ‘value of the ELSA role & training’ and ‘a better understanding of the ELSA values’. The third occurring main theme was ‘benefits of ELSA for children and TAs’, with the sub themes ‘developing personal skills’ and ‘benefits for children’. The final occurring main theme was and ‘low self-efficacy and confidence’ with the sub themes ‘self-efficacy for the ELSA role’ and ‘fears and loneliness of ELSA role’.

Who was the cowboy in Washington? What is the land of sushi? Most people would have answers to these questions readily available,yet, modern search engines, arguably the epitome of technology in finding answers to most questions, are completely unable to do so. It seems that people capture few information items to rapidly converge to a seemingly 'obvious' solution. We will study approaches for this problem, with two additional hard demands that constrain the space of possible theories: the sought model must be both psychologically and neuroscienti cally plausible. Building on top of the mathematical model of memory called Sparse Distributed Memory, we will see how some well-known methods in cryptography can point toward a promising, comprehensive, solution that preserves four crucial properties of human psychology.

L'inclusion de requête est un problème bien étudié durant plusieurs décen- nies de recherche. En règle générale, il est défini comme le problème de déterminer si le résultat d'une requête est inclus dans le résultat d'une autre requête pour tout ensem- ble de données. Elle a des applications importantes dans l'optimisation des requêtes et la vérification de bases de connaissances. L'objectif principal de cette thèse est de fournir des procédures correctes et complètes pour déterminer l'inclusion des requêtes SPARQL en vertu d'axiomes exprimés en logiques de description. De plus, nous met- tons en œuvre ces procédures à l'appui des résultats théoriques par l'expérimentation. À ce jour, l'inclusion de requête a été testée à l'aide de différentes techniques: ho- momorphisme de graphes, bases de données canoniques, les techniques de la théorie des automates et réduction au problème de la validité d'une logique. Dans cette thèse, nous utilisons la derniere technique pour tester l'inclusion des requêtes SPARQL utilisant une logique expressive appelée le μ-calcul. Pour ce faire, les graphes RDF sont codés comme des systèmes de transitions, et les requêtes et les axiomes du schéma sont codés comme des formules de μ-calcul. Ainsi, l'inclusion de requêtes peut être réduite au test de la validité d'une formule logique. Dans cette thèse j'identifier les divers fragments de SPARQL (et PSPARQL) et les langages de description logique de schéma pour lequelle l'inculsion est décidable. En outre, afin de fournir théoriquement et expérimentalement des procédures éprouvées pour vérifier l'inclusion de ces fragments décidables. Enfin, cette thèse propose un point de repère pour les solveurs d'inclusion. Ce benchmark est utilisé pour tester et comparer l'état actuel des solveurs d'inclusion.

In computer science, an ontology is a machine-processable representation of knowledge about some domain. Ontologies are encoded in ontology languages, such as the Web Ontology Language (OWL) based on Description Logics (DLs). An ontology is a set of logical statements, called axioms. Some axioms make universal statements, e.g. all fathers are men, while others record data, i.e. facts about specific individuals, e.g. Bob is a father. A set of universal statements is called TBox, as it encodes terminology, i.e. schema-level conceptual relationships, and a set of facts is called ABox, as it encodes instance-level assertions. Ontologies are extensively developed and widely used in domains such as biology and medicine. Manual engineering of a TBox is a difficult task that includes modelling conceptual relationships of the domain and encoding those relationships in the ontology language, e.g. OWL. Hence, it requires the knowledge of domain experts and skills of ontology engineers combined together. In order to assist engineering of TBoxes and potentially automate it, acquisition (or induction) of axioms from data has attracted research attention and is usually called Ontology Learning (OL). This thesis investigates the problem of OL from general principles. We formulate it as General Terminology Induction that aims at acquiring general, expressive TBox axioms (called general terminology) from data. The thesis addresses and investigates in depth two main questions: how to rigorously evaluate the quality of general TBox axioms and how to efficiently construct them. We design an approach for General Terminology Induction and implement it in an algorithm called DL-Miner. We extensively evaluate DL-Miner, compare it with other approaches, and run case studies together with domain experts to gain insight into its potential applications. The thesis should be of interest to ontology developers seeking automated means to facilitate building or enriching ontologies. In addition, as our experiments show, DL-Miner can deliver valuable insights into the data, i.e. can be useful for data analysis and debugging.

This thesis introduces a novel approach in which multiple heterogeneous devices collaborate to provide useful applications in an ad-hoc network. This thesis proposes a smart home as a particular ubiquitous computing scenario considering all the requirements given by the literature for succeed in this kind of systems. To that end, we envision a horizontally integrated smart home built up from independent components that provide services. These components are described with enough syntactic, semantic and pragmatic knowledge to accomplish spontaneous collaboration. The objective of these collaboration is domestic use, that is, the provision of valuable services for home residents capable of supporting users in their daily activities. Moreover, for the system to be attractive for potential customers, it should offer high levels of trust and reliability, all of them not at an excessive price. To achieve this goal, this thesis proposes to study the synergies available when an ontological description of home device functionality is paired with a formal method. We propose an ad-hoc home network in which components are home devices modelled as processes represented as semantic services by means of the Web Service Ontology (OWL-S). In addition, such services are specified, verified and implemented by means of the Communicating Sequential Processes (CSP), a process algebra for describing concurrent systems. The utilisation of an ontology brings the desired levels of knowledge for a system to compose services in a ad-hoc environment. Services are composed by a goal based system in order to satisfy user needs. Such system is capable of understaning, both service representations and user context information. Furthermore, the inclusion of a formal method contributes with additional semantics to check that such compositions will be correctly implemented and executed, achieving the levels of reliability and costs reduction (costs derived form the design, development and implementation of the system) needed for a smart home to succeed.

Le travail de thèse présenté dans ce document porte sur la conception d'un service de validation et d'enrichissement d'annotations pour un outil industriel de gestion des connaissances basé sur le langage des Topic Maps (TM). Un tel service nécessitant la mise en oeuvre de raisonnements sur les connaissances, il a été nécessaire de doter le langage des TM d'une sémantique formelle. Ceci a été réalisé par l'intermédiaire d'une transformation réversible des TM vers le formalisme logique des graphes conceptuels qui dispose d'une représentation graphique des connaissances (les TM pouvant facilement en être munie d'une). La solution a été mise en oeuvre dans deux applications, l'une conçue pour la veille médiatique et l'autre pour la promotion de ressources touristiques. Schématiquement, des annotations sont extraites automatiquement des documents selon le domaine concerné (actualité/économie ou tourisme) puis ajoutées à la base de connaissances. Elles sont ensuite fournies au service d'enrichissement et de validation qui les complète de nouvelles connaissances et décide de leur validité, puis retourne à la base de connaissance le résultat de l'enrichissement et de la validation.

World Wide Web has become the main place for searching information on any topic. This
makes searching a key activity and thus, search engines the most widely used tools on the
Web. However, as the Web continues to expand, the portion of the Web covered by each
search engine is decreasing constantly. Metasearch engines address this issue by combining
the results of multiple search engines and thereby increasing the search effectiveness. This
research work proposes a new model for metasearch, MetaXplorer, which is both intelligent
and adaptable. This research work also proposes a novel Ordered Weighted Averaging
operator named Intelligent OWA operator, which is capable of handling the dynamic nature
of decision making environment. The proposed Intelligent OWA operator is used for result
aggregation in MetaXplorer, along with Fuzzy Analytical Hierarchy Process. Furthermore,
MetaXplorer analyses the documents returned by individual search engines instead of
considering their ranks in search engine result lists alone in the aggregation process, and thus
is intelligent. Subjective evaluation of MetaXplorer is provided by comparing it with
previously proposed models. This research work also performs the performance evaluation of
MetaXplorer in terms of precision. The precision values for MetaXplorer are compared with
three existing metasearch engines on the Web. The results indicate that MetaXplorer
performs better than the existing metasearch engines and has several features which were not
present in the previous models.

This study is to develop the best heat diffusion system, under the 2010 NSC financial support industry-academic project, for heat-generated transistor inside the intelligent junction box, which is developed and manufacture by Taihe Optoelectronic for the solar PV panel. Additional to the function of traditional junction boxes is used for outputting electricity to loads from PV panel, this intelligent junction box also features the following advantages：(1)The maximum power output of PV panels is auto controlled. (2) The decrease of efficiency due to cloud shadow and dust accumulation is reduced to minimum. (3) A mechanism of the prevention for battery overcharging is designed. The intelligent junction box’s control system is powered by part of the DC electricity generated by the solar panels. However, the temperature in its transistors can be heated up to 170℃ during the operation. Therefore, the transistors inside intelligent box need to be cooled down to prevent failure due to the high temperature, and this is what our study project is focusing on. Taihe Optoelectronic used the following methods to do the experiments for the diffusion problem: (1)3M thermal-conduction and electricity-insulation back glue; (2)copper pressed plate and electricity-insulation cloth; (3) thermal-conduction and electricity-insulation glue belt with thermal grease. And our study uses heat pipe with various saturation temperatures and electricity-insulation glue belt with thermal grease to do the experiments for the diffusion problem. Because the test specification of junction box in the ambient temperature from -40 ℃ to 65 ℃, the transistors can operation normally and the box surface temperature must be less than 70 ℃. It is found that the above three methods adopted by Taihe and 78℃ saturation temperature of heat pipe adopted by our study are qualified the conditions of test specification while the ambient temperature is less than 40 ℃. But for the 65 ℃ ambient temperature, only 78℃ saturation temperature of heat pipe adopted by our study can satisfy the required test specification. Therefore, the Taihe Optoelectronic should use the 78℃ saturation temperature of heat pipe as a heat diffusion system for transistor inside the intelligent junction box to meet the requirement of strict testing specification.

Intelligence as a psychological construct has received vast attention from professionals and lay persons. The theory of multiple intelligences as a perspective of understanding intelligence has enjoyed extensive research. The present study took advantage of the theory of multiple intelligences as stipulated by Gardner (1983), which puts fourth seven types of intelligences (verbal/linguistic, bodily – kinesthetic, musical, logical/mathematical, spatial, interpersonal and intrapersonal intelligence). The aim of the study was to investigate the relationship between these types of intelligences and gender, age and education. Participants comprised of 83 female and 75 male university students between the ages of 18 years and 50 years. Participants were requested to estimate their own and their parents’ scores for the seven multiple intelligences and overall intelligence. For parents’ estimates on overall and multiple intelligences, there was no statistically significant difference in those types of intelligences traditionally associated with females (musical, interpersonal, intrapersonal intelligences) and those traditionally associated with males (logical and verbal intelligences). Parents’ level of education had a significant impact on their estimated levels of intelligence; those parents in the Diploma/Degree category were rated as statistically significantly more intelligent than those in the No Diploma/Degree category. The mothers in the Diploma/Degree category were rated as significantly more intelligent on overall, verbal, logical, spatial, musical, and interpersonal intelligences, while the fathers in the same category were estimated as significantly more intelligent on overall, verbal and logical intelligences. Future studies on lay persons’ conceptions of intelligence should include more refined measures of socio-economic status and level of education. Qualitative investigations into the meaning of intelligence in different cultural contexts are also needed.Thesis (M.Soc.Sci.)-University of KwaZulu-Natal, Pietermaritzburg, 2013.

intelligence. The participants were asked to complete a brief one-page questionnaire, the
'estimates of intelligence' questionnaire, which has been used in previous studies in this field

The results indicated that Indian South Africans gave higher estimates of intelligence than
Black South Africans for their own intelligence and that of their children (first and secondborn
children). In addition, mothers were found to give higher self-estimates for musical
intelligence than their male counterparts. No gender differences were found for parents'
estimates of their first and second-born children. In comparing parents' estimates of their
own intelligence as compared to their children, parents gave higher estimates of their own
intelligence. The predictors of overall intelligence were also explored. Parents were also
asked to answer six close-ended questions, which investigated their views of intelligence and

Dissertation submitted in partial fulfilment of the requirements for the Degree of Master of Science in Geospatial TechnologiesFolksonomy (from folk and taxonomy) is an approach to user metadata creation where users describe information objects with a free-form list of keywords (‘tags’). Folksonomy has have proved to be a useful information retrieval tool that support the emergence of “collective intelligence” or “bottom-up” light weight semantics. Since there are no guiding rules or restrictions on the users, folksonomy has some drawbacks and problems as lack of hierarchy, synonym control, and semantic precision. This research aims at enhancing information retrieval in folksonomy, particularly that of location information, by establishing explicit relationships between place name tags. To accomplish this, an automated approach is developed. The approach starts by retrieving tags from Flickr. The tags are then filtered to identify those that represent place names. Next, the gazetteer service that is a knowledge organization system for spatial information is used to query for the place names. The result of the search from the gazetteer and the feature types are used to construct an ontology of place. The ontology of place is formalized from place name concepts, where each place has a “Part-Of” relationship with its direct parent. The ontology is then formalized in OWL (Web Ontology Language). A search tool prototype is developed that extracts a place name and its parent name from the ontology and use them for searching in Flickr. The semantic richness added to Flickr search engine using our approach is tested and the results are evaluated.

Action planning has been used in the field of robotics for solving long-running tasks. In the robot architectures field, it is also known as the deliberative layer. However, there is still a gap between the symbolic representation on the one hand and the low-level control and sensor representation on the other. In addition, the definition of a planning problem for a complex, real-world robot is not trivial. The planning process could become intractable as its search spaces become large. As the defined planning problem determines the complexity and the computationability for solving the problem, it should contain only relevant states. In this work, a novel approach which amalgamates Description Logic (DL) reasoning with Hierarchical Task Network (HTN) planning is introduced.
The planning domain description as well as fundamental HTN planning concepts are represented in DL and can therefore be subject to DL reasoning; from these representations, concise planning problems are generated for HTN planning. The method is presented through an
example in the robot navigation domain. In addition, a case study of the RoboCup@Home domain is given. As proof of concept, a well-known planning problem that often serves as a benchmark, namely that of the blocks-world, is modeled and solved using this approach.
An analysis of the performance of the approach has been conducted and the results show that this approach yields significantly smaller planning problem descriptions than those generated by current representations in HTN planning.

Die Bezeichnung der Elemente in diesen Modellen ist dabei an betriebswirtschaftliche Fachtermini angelehnt und erfolgt mit Hilfe der natürlichen Sprache, die jedoch Interpretationsspielräume mit sich bringt. Die Semantik der einzelnen Modellelemente ist somit für Menschen und Maschinen nicht eindeutig interpretierbar. In der vorliegenden Dissertation erfolgt daher die Konzeption und Realisierung einer semantischen Prozessmodellierung, die die Verknüpfung der semiformalen Prozessmodellierung mit formalen Begriffssystemen (Ontologien) gestaltet und werkzeugtechnisch unterstützt. Durch diese Verknüpfung wird die Semantik der einzelnen Modellelemente um eine eindeutige und maschinell verarbeitbare Semantik erweitert. Hierdurch können die mit formalen Ontologien möglichen Schlussfolgerungen angewendet werden, um etwa bei der Suche in Modellbeständen oder der Korrektheitsprüfung genauere oder vollständigere Ergebnisse zu erhalten. Im Ergebnis werden somit die im Bereich der Informatik und Künstlichen Intelligenz etablierten Ansätze der Wissensrepräsentation, insbesondere der Beschreibungslogik, in die fachlichen Prozessmodellierung eingebettet. Die Erprobung des Konzepts erfolgt über eine prototypische Implementierung, die einerseits die technische Umsetzbarkeit zeigt, andererseits auch für ein Laborexperiment zur Evaluation genutzt wurde.

This dissertation describes a research study conducted to determine the benefits and
use of ontology technologies to support a simulation environment that evaluates
countermeasures employed to protect military aircraft.
Within the military, aircraft represent a significant investment and these valuable assets
need to be protected against various threats, such as man-portable air-defence
systems. To counter attacks from these threats, countermeasures are deployed, developed
and evaluated by utilising modelling and simulation techniques. The system
described in this research simulates real world scenarios of aircraft, missiles and
countermeasures in order to assist in the evaluation of infra-red countermeasures
against missiles in specified scenarios.
Traditional ontology has its origin in philosophy, describing what exists and how
objects relate to each other. The use of formal ontologies in Computer Science have
brought new possibilities for modelling and representation of information and knowledge
in several domains. These advantages also apply to military information systems
where ontologies support the complex nature of military information. After considering
ontologies and their advantages against the requirements for enhancements
of the simulation system, an ontology was constructed by following a formal development
methodology. Design research, combined with the adaptive methodology
of development, was conducted in a unique way, therefore contributing to establish
design research as a formal research methodology. The ontology was constructed
to capture the knowledge of the simulation system environment and the use of it
supports the functions of the simulation system in the domain.
The research study contributes to better communication among people involved in
the simulation studies, accomplished by a shared vocabulary and a knowledge base
for the domain. These contributions affirmed that ontologies can be successfully use
to support military simulation systemsComputing

SweetDeal is a rule-based approach to representation of business contracts that enables software agents to create, evaluate, negotiate, and execute contracts with substantial automation and modularity. It builds upon the situated courteous logic programs knowledge representation in RuleML, the emerging standard for Semantic Web XML rules. Here, we newly extend the SweetDeal approach by also incorporating process knowledge descriptions whose ontologies are represented in DAML+OIL (the close predecessor of W3C's OWL, the emerging standard for Semantic Web ontologies), thereby enabling more complex contracts with behavioral provisions, especially for handling exception conditions (e.g., late delivery or non-payment) that might arise during the execution of the contract. This provides a foundation for representing and automating deals about services – in particular, about Web Services, so as to help search, select, and compose them. We give a detailed application scenario of late delivery in manufacturing supply chain management (SCM). In doing so, we draw upon our new formalization of process ontology knowledge from the MIT Process Handbook, a large, previously-existing repository used by practical industrial process designers. Our system is the first to combine emerging Semantic Web standards for knowledge representation of rules (RuleML) with ontologies (DAML+OIL/OWL) with each other, and moreover for a practical e-business application domain, and further to do so with process knowledge. This also newly fleshes out the evolving concept of Semantic Web Services. A prototype (soon public) i

Most nursing quality studies based on the structure-process-outcome paradigm have concentrated on structure-outcome associations and have not explained the nursing process domain. This thesis turns the spotlight on the process domain and visualises nursing processes or ‘what nurses do’ by using ‘semantics’ which underpin Linking Of Data (LOD) technologies such as ontologies. Ontology construction has considerable limitations that make direct input of nursing process semantics difficult. Consequently, nursing ontologies being constructed to date use nursing process semantics collected by non-clinicians. These ontologies may have undesirable clinical implications when they are used to map nurse processes to patient outcomes. To address this issue, this thesis places nurses at the centre of semantic collection and ontology construction.
