LITCHI: knowledge integrity testing for taxonomic databases
No full textThe Logic-based Integration of Taxonomic Conflicts in Heterogeneous Information Systems (LITCHI) project is initiated with the aim of developing software to enable the automated detection and, where possible, resolution of conflicts in taxonomic checklists. To support this project, a formal model is constructed of the way scientific names are used to denote taxa in common taxonomic practice. The model is then used to derive sets of Prolog rules which will detect conflicts in taxonomic checklists stored in a relational DBMS
Assisting the integration of taxonomic data: The LITCHI toolkit
No full textThe prototype toolkit, called LITCHI, uses constraints and constraint violation repair techniques to enable the automated detection and, where possible, the automated resolution of conflicts in taxonomic databases. The LITCHI software has been used successfully on various test sets. LITCHI has led to the discovery that individual checklists are less consistent than had been anticipated, although its initial purpose was to detect conflicts between distinct checklists
Techniques for effective integration, maintenance and evolution of species databases
No full textThe LITCHI project is concerned with the integration and maintenance of databases of biological knowledge organized by species. We use constraints pertaining to good taxonomic practice in order to identify taxonomic conflicts in individual species databases and in databases formed by merging species databases from distinct sources. The LITCHI system can be used to resolve such conflicts incrementally. As the project has progressed, we have identified a number of distinctive features of the problem domain, and needs of the intended users, which have had a significant impact on the techniques and modes of operation that we found to be appropriate, especially in contrast with applications that handle rapidly-accumulating `raw' data. It is upon these aspects of LITCHI that we concentrate in the present paper, viewing LITCHI as an example of the more general problem of merging scientific data sets in which conflicts between the terminology used can occur
Conflict detection for integration of taxonomic data sources
No full textThe LITCHI project aims to assist biologists in the integration of database by searching for conflicts within taxonomix checklists. In order to detect such conflicts, a formal model of taxonomic practice has been created and used as the basis for a prototype tool that uses Prolog search for naming conflicts within a relational database of checklists. The prototype tool is already proving its worth by detecting conflicts and errors within real taxonomic checklists
Factors affecting commitment to a plan of physical activity among low-income Hispanic mothers and their daughters
No full textThe purpose of this research was to examine the relationships among societal norms, exercise self-efficacy and activity related affect on commitment to a plan of physical activity in a sample of low-income Hispanic women and their daughters. Theoretical propositions derived from the Health Promotion Model (Pender, 2011) were tested. The first hypothesis, which stated there would be a significant relationship between societal norms and commitment, was partially supported. The second hypothesis, which stated there would be a significant relationship between exercise self-efficacy and commitment, was partially supported. The third hypothesis, which stated there would be a significant relationship between related affect and commitment to a plan of physical activity, was partially supported. The fourth hypothesis, which stated there would be significant relationship between commitment to a plan of physical activity and participation in physical activity, was partially supported. The fifth hypothesis, which stated there would be a significant relationship between societal norms, self-efficacy, activity related affect and commitment to a plan of physical activity of mothers will be significant predictors of physical activity levels of the daughters, was partially supported. The sixth hypothesis, which stated there would be a significant differences in societal norms, exercise self-efficacy, activity related affect and commitment to exercise between Hispanic women and their daughters was partially supported. Evidence in support of these hypotheses was found among daughters, in relation societal norms and exercise self efficacy, but not mothers. Data was collected at area Hispanic churches. (N= 79) Hispanic mothers and (N= 79) Hispanic daughters. A correlational designed was used. Kendall’s tau_b was used to assess differences between means of mothers and daughters. Actigraph were used in this study for quantitative measurements, which demonstrated low levels of physical activities among mothers and daughters, with both mothers and daughters being in sedentary activity (71%) while they wore the actigraph. Multiple regression did not reveal significant relationships between societal norms, exercise self-efficacy and physical activity enjoyment on a commitment to physical activity with the mothers, and the R2 = .04 which explains only 4% of the variance for mothers’ commitment for physical activity. Multiple regression did however real a relationship between the daughters’ independent variables, societal norms, β = .28, p = .01; and exercise self-efficacy, β = .25, p = .02. The total R2 = .213 which explains 21% of the variance for the daughters’ commitment for PA, which is not a strong predictor for commitment of physical activity. Limitations of this study was the language barrier, limited access to Actigraphs,® and seasonal winter months may have reduced physical activity. Further research is needed with the Hispanic population especially with the key predictor variable of being physically active, exercise self-efficacy. Implication for nurses include education for why and how to be physically active, and to provide physically activity programs that are culturally specific for this population that would provide enjoyment and therefore a commitment to physical activity.Ph.

Assessment of Time Management Skills: Psychometric Properties of the Swedish Version (ATMS–S)
No full textAbstract
Date Presented 3/31/2017
The Assessment of Time Management Skills–Swedish Version (ATMS–S) is a promising, easily administered self-rating of daily time management. The ATMS–S provides occupational therapists a structured way to assess clients who have reduced time management skills due to higher-level cognitive disorders.

Littoral Space(s): Liquid Edges of Poetic Possibility
No full textIslands have inspired a history of folklore, literary genres and artistic visual work, continually captivating human creativity and imagination. This multi‐media article presents work that moves beyond traditional boundaries of the educational field to link nationally with the Institute of Island Studies, located at the University of Prince Edward Island, Canada, and internationally with the Small Island Cultures Research Initiative, hosted by the Island Cultures Centre at Macquarie University in Sydney, Australia. Through the vehicle of video, interweaving imagery and improvisational music, the artist‐researcher examines island as a distinctive geographical site and the spatial dimensions of island locality. The author applies methods of visual poetic inquiry while integrating perspectives of image‐based arts with disciplines of island studies, philosophy, and human/cultural geography. The intentionality of the work is to stimulate a
multi‐layered “trans‐disciplinary” approach (Baldacchino, 2006) to island studies and qualitative research and to represent the emergent process of developing an island aesthetic methodology. The aim of the article is to expand island studies as an artistic inter‐discipline and to contribute to the growing theory of islandness or “nissology” (McCall, 1996).Adobe Premier VideoSource type: Electronic(1
