Principles of Sampling in Educational Research in Higher Education

Innovation and creativity in European society are fostered via a dynamic and flexible European higher education based on the integration between education and research at all levels (Communiqué, 2009). The synergy between education and research is effeciently driven via educational research. Sampling as an element of the educational research has a two-fold role: sample size is inter-connected with statistical analysis of the data and generalisation. Against this background, little attention has been given to principles of sampling in educational research. The research question is as follows: what principles form sampling in educational research? The aim of the research is to analyse scientific literature and work out principles of sampling in educational research underpinning elaboration of a new research question for further studies in educational research. The present research involves a process of analysing the meaning of the key concept “principle”. In the empirical study, explorative research was employed. Interpretive research paradigm was used. The empirical study involved six experts from different countries in February 2013 – July 2014. The findings of the research allow drawing the conclusions on the elaborated principles of sampling in educational research. Directions of further research are proposed

DEVELOPMENT OF ADULT LEARNERS’ 21ST CENTURY SKILLS IN GREENLAND: FIELD WORK ANALYSIS

The expansion of adult education has been presented as an effective strategy to solve the issues in adult employment. The aim of the present research is to analyse the field work carried out in Nuuk (Greenland) on the development of adult learners’ 21st century skills in Greenland underpinning the elaboration of implications for adult education in Greenland. The methods of the present research comprise both theoretical and empirical methods. The empirical study was based on fieldwork. Two on-site visits in Nuuk between the 8-12th August 2022 were carried out. Observation and participant observation were implemented. A semi-structured interview with two interviewees was conducted. The literature review allows for a conclusion that adult education in Greenland is mentioned neither in Greenland educational policy documents or scientific publications. Despite that, the analysis of the implemented fieldwork allows drawing a conclusion that adult education has been established on a municipal level like the centre Majoriaq, and on a non-governmental level like Kofoeds Skole. Both theoretical and empirical analysis contribute to the conclusion that adult learners’ 21st century skills in Greenland are being developed. However, these skills would need more joint work from all the adult education stakeholders.

COMPARISON OF TEACHER’S AND STUDENTS’ RANKING OF ENGLISH FOR ACADEMIC PURPOSES SUB-TOPICS

Ranking implemented in the English for Academic Purposes course helps in selecting appropriate sub-topics to be obtained by students. The aim of the present research is to compare teacher’s and students’ ranking of topics of the English for Academic Purposes course delivered to master of engineering students underpinning the elaboration of implications for the advancement of the English for Academic Purposes course. Research methods applied include the use of theoretical as well as empirical methods. Theoretical methods imply analysis of theoretical sources and theoretical modelling. The empirical study was characterized by its explorative nature. The empirical study was based on a survey carried out with 10 engineering master students of the Master programme “Information and Electrical Engineering” at Hochschule Wismar, Germany. The data were interpreted and summarized. The summarizing content analysis allows proposing that the students positively evaluated the majority of the sub-topics of the delivered English for Academic Purposes course. The hypothesis was formulated. Implications for the advancement of the English for Academic Purposes course were identified. Directions of future work were proposed. The novelty of the research is revealed by the formulated hypothesis as well as implication

Applications of ontology in the Internet of Things: a systematic analysis

Ontology has been increasingly implemented to facilitate the Internet of Things (IoT) activities, such as tracking and information discovery, storage, information exchange, and object addressing. However, a complete understanding of using ontology in the IoT mechanism remains lacking. The main goal of this research is to recognize the use of ontology in the IoT process and investigate the services of ontology in IoT activities. A systematic literature review (SLR) is conducted using predefined protocols to analyze the literature about the usage of ontologies in IoT. The following conclusions are obtained from the SLR. (1) Primary studies (i.e., selected 115 articles) have addressed the need to use ontologies in IoT for industries and the academe, especially to minimize interoperability and integration of IoT devices. (2) About 31.30% of extant literature discussed ontology development concerning the IoT interoperability issue, while IoT privacy and integration issues are partially discussed in the literature. (3) IoT styles of modeling ontologies are diverse, whereas 35.65% of total studies adopted the OWL style. (4) The 32 articles (i.e., 27.83% of the total studies) reused IoT ontologies to handle diverse IoT methodologies. (5) A total of 45 IoT ontologies are well acknowledged, but the IoT community has widely utilized none. An in-depth analysis of different IoT ontologies suggests that the existing ontologies are beneficial in designing new IoT ontology or achieving three main requirements of the IoT field: interoperability, integration, and privacy. This SLR is finalized by identifying numerous validity threats and future directions

A Review of Instrumented Equipment to Investigate Head Impacts in Sport

Contact, collision, and combat sports have more head impacts as compared to noncontact sports; therefore, such sports are uniquely suited to the investigation of head impact biomechanics. Recent advances in technology have enabled the development of instrumented equipment, which can estimate the head impact kinematics of human subjects in vivo. Literature pertaining to head impact measurement devices was reviewed and usage, in terms of validation and field studies, of such devices was discussed. Over the past decade, instrumented equipment has recorded millions of impacts in the laboratory, on the field, in the ring, and on the ice. Instrumented equipment is not without limitations; however, in vivo head impact data is crucial to investigate head injury mechanisms and further the understanding of concussion

A document based traceability model for test management

Software testing has became more complicated in the emergence of distributed network, real-time environment, third party software enablers and the need to test system at multiple integration levels. These scenarios have created more concern over the quality of software testing. The quality of software has been deteriorating due to inefficient and ineffective testing activities. One of the main flaws is due to ineffective use of test management to manage software documentations. In documentations, it is difficult to detect and trace bugs in some related documents of which traceability is the major concern. Currently, various studies have been conducted on test management, however very few have focused on document traceability in particular to support the error propagation with respect to documentation. The objective of this thesis is to develop a new traceability model that integrates software engineering documents to support test management. The artefacts refer to requirements, design, source code, test description and test result. The proposed model managed to tackle software traceability in both forward and backward propagations by implementing multi-bidirectional pointer. This platform enabled the test manager to navigate and capture a set of related artefacts to support test management process. A new prototype was developed to facilitate observation of software traceability on all related artefacts across the entire documentation lifecycle. The proposed model was then applied to a case study of a finished software development project with a complete set of software documents called the On-Board Automobile (OBA). The proposed model was evaluated qualitatively and quantitatively using the feature analysis, precision and recall, and expert validation. The evaluation results proved that the proposed model and its prototype were justified and significant to support test management

RDF graph validation using rule-based reasoning

The correct functioning of Semantic Web applications requires that given RDF graphs adhere to an expected shape. This shape depends on the RDF graph and the application's supported entailments of that graph. During validation, RDF graphs are assessed against sets of constraints, and found violations help refining the RDF graphs. However, existing validation approaches cannot always explain the root causes of violations (inhibiting refinement), and cannot fully match the entailments supported during validation with those supported by the application. These approaches cannot accurately validate RDF graphs, or combine multiple systems, deteriorating the validator's performance. In this paper, we present an alternative validation approach using rule-based reasoning, capable of fully customizing the used inferencing steps. We compare to existing approaches, and present a formal ground and practical implementation "Validatrr", based on N3Logic and the EYE reasoner. Our approach - supporting an equivalent number of constraint types compared to the state of the art - better explains the root cause of the violations due to the reasoner's generated logical proof, and returns an accurate number of violations due to the customizable inferencing rule set. Performance evaluation shows that Validatrr is performant for smaller datasets, and scales linearly w.r.t. the RDF graph size. The detailed root cause explanations can guide future validation report description specifications, and the fine-grained level of configuration can be employed to support different constraint languages. This foundation allows further research into handling recursion, validating RDF graphs based on their generation description, and providing automatic refinement suggestions
