Complex adaptive systems based data integration : theory and applications

Data Definition Languages (DDLs) have been created and used to represent data in programming languages and in database dictionaries. This representation includes descriptions in the form of data fields and relations in the form of a hierarchy, with the common exception of relational databases where relations are flat. Network computing created an environment that enables relatively easy and inexpensive exchange of data. What followed was the creation of new DDLs claiming better support for automatic data integration. It is uncertain from the literature if any real progress has been made toward achieving an ideal state or limit condition of automatic data integration. This research asserts that difficulties in accomplishing integration are indicative of socio-cultural systems in general and are caused by some measurable attributes common in DDLs. This research’s main contributions are: (1) a theory of data integration requirements to fully support automatic data integration from autonomous heterogeneous data sources; (2) the identification of measurable related abstract attributes (Variety, Tension, and Entropy); (3) the development of tools to measure them. The research uses a multi-theoretic lens to define and articulate these attributes and their measurements. The proposed theory is founded on the Law of Requisite Variety, Information Theory, Complex Adaptive Systems (CAS) theory, Sowa’s Meaning Preservation framework and Zipf distributions of words and meanings. Using the theory, the attributes, and their measures, this research proposes a framework for objectively evaluating the suitability of any data definition language with respect to degrees of automatic data integration. This research uses thirteen data structures constructed with various DDLs from the 1960\u27s to date. No DDL examined (and therefore no DDL similar to those examined) is designed to satisfy the law of requisite variety. No DDL examined is designed to support CAS evolutionary processes that could result in fully automated integration of heterogeneous data sources. There is no significant difference in measures of Variety, Tension, and Entropy among DDLs investigated in this research. A direction to overcome the common limitations discovered in this research is suggested and tested by proposing GlossoMote, a theoretical mathematically sound description language that satisfies the data integration theory requirements. The DDL, named GlossoMote, is not merely a new syntax, it is a drastic departure from existing DDL constructs. The feasibility of the approach is demonstrated with a small scale experiment and evaluated using the proposed assessment framework and other means. The promising results require additional research to evaluate GlossoMote’s approach commercial use potential

The use of over-the-counter medicine and health information seeking behaviour in England

Background. In England and the UK there has been a move to provide the consumer with more choice in over the counter medicine. In recognition of the number of drugs now available without prescription, new models and frameworks are being utilised with the aim to educate the public about self-treatment. How health information is sought has also undergone transformation with the advent of the internet, the adoption and utilisation of this resource has had a significant impact on how the healthcare consumer seeks information. Aims and Methods. The aim of this study was to investigate the provision of and access to consumer health information in England, specifically with reference to over the counter medicines to promote understanding of the consumers attitudes and opinions to this type of medicine and their health information seeking behaviours. The findings of the study were used to provide recommendations to the stakeholders involved; healthcare organisations, healthcare professionals and the healthcare consumer. The research consisted of a survey (n=324) and was analysed using quantitative and qualitative methods. Results. The majority of respondents utilised over the counter medicine responsibly and with few adverse events. The General Practitioner is the main source of information and online sources the next most utilised resource. Effectiveness and following advice/recommendations were amongst the themes identified that made a treatment episode with over the counter medicines successful. Unsuccessful treatment episodes included those with escalation of symptoms. Factors governing successful health information seeking were problem solving through self diagnosis and expanding knowledge on an existing health issue. Conclusions. Over the counter medicines are a widely used commodity but respondents continue to have a heavy reliance on the general practitioner for prescription medicines, especially for minor ailments. Evidence exists that individuals utilise information seeking behaviour for self treatment and the use of over the counter medicines. However, adoption of self care models need to be increased through educating health care consumers to maximise the potential benefits of these frameworks for the stakeholders

Unmet goals of tracking: within-track heterogeneity of students' expectations for

Educational systems are often characterized by some form(s) of ability grouping, like tracking. Although substantial variation in the implementation of these practices exists, it is always the aim to improve teaching efficiency by creating homogeneous groups of students in terms of capabilities and performances as well as expected pathways. If students’ expected pathways (university, graduate school, or working) are in line with the goals of tracking, one might presume that these expectations are rather homogeneous within tracks and heterogeneous between tracks. In Flanders (the northern region of Belgium), the educational system consists of four tracks. Many students start out in the most prestigious, academic track. If they fail to gain the necessary credentials, they move to the less esteemed technical and vocational tracks. Therefore, the educational system has been called a 'cascade system'. We presume that this cascade system creates homogeneous expectations in the academic track, though heterogeneous expectations in the technical and vocational tracks. We use data from the International Study of City Youth (ISCY), gathered during the 2013-2014 school year from 2354 pupils of the tenth grade across 30 secondary schools in the city of Ghent, Flanders. Preliminary results suggest that the technical and vocational tracks show more heterogeneity in student’s expectations than the academic track. If tracking does not fulfill the desired goals in some tracks, tracking practices should be questioned as tracking occurs along social and ethnic lines, causing social inequality
