A retrospective lyrical analysis of songs written by adolescents with anorexia nervosa

Song-writing plays a central role in music therapy with adolescents. A retrospective lyrical analysis of songs written by adolescents with anorexia nervosa was undertaken in order to identify common themes solicited through song-writing interventions. Fifteen participants contributed 17 songs, from which 368 lyrical units were identified. A modified content analysis approach was used with each lyrical unit being categorised to one of six themes determined from the literature and clinical experience. The theme of 'identity' was used most frequently (28%), with the sub-theme of 'exploring new behaviours, positive self-talk' being addressed most often (12.5% of total). The dominance of the developmentally important theme of 'identity' may reflect the relationship between adolescents, music and identity or may be related to the way in which anorexia nervosa has been theorised to assist the adolescent in managing challenges to the emerging sense of self.

Career development: A project for the 21st century

This article reports of the papers present at the International Symposium 2006 'Shaping the future: connecting career development and workforce development'. The International Symposium 2006 provided an opportunity to move the project forward by considering career development in relation to the workforce development issues of human capital, labour supply, employability skills and older workers. In addition to these specific issues, it examined the broader issues of how career development services might contribute to workforce development and the career development information base needed to support public policy making. By way of background to this special issue on the International Symposium 2006, this paper briefly examines the context and the reasons behind career development's rise to a more prominent position on the public policy arena. Following this, the process of the International Symposium 2006 that resulted in the writing of the documents contained in the special issue are briefly outlined.

Termination of real-time programs: Definitely, definitely not, or maybe

Real-time control programs are often used in contexts where (conceptually) they run forever. Repetitions within such programs (or their specifications) may either (i) be guaranteed to terminate, (ii) be guaranteed to never terminate (loop forever), or (iii) may possibly terminate. In dealing with real-time programs and their specifications, we need to be able to represent these possibilities, and define suitable refinement orderings. A refinement ordering based on Dijkstra's weakest precondition only copes with the first alternative. Weakest liberal preconditions allow one to constrain behaviour provided the program terminates, which copes with the third alternative to some extent. However, neither of these handles the case when a program does not terminate. To handle this case a refinement ordering based on relational semantics can be used. In this paper we explore these issues and the definition of loops for real-time programs as well as corresponding refinement laws.

Teaching principles of genetics through SNP analysis

An understanding of inheritance requires comprehension of genetic processes at all levels, from molecules to populations. Frequently genetics courses are separated into molecular and organismal genetics and students may fail to see the relationships between them. This is particularly true with human genetics, because of the difficulties in designing experimental approaches which are consistent with ethical restrictions, student abilities and background knowledge, and available time and materials. During 2005 we used analysis of single nucleotide polymorphisms (SNPs) in two genetic regions to enhance student learning and provide a practical experience in human genetics. Students scanned databases to discover SNPs in a gene of interest, used software to design PCR primers and a restriction enzyme based assay for the alleles, and carried out an analysis of the SNP on anonymous individual and family DNAs. The project occupied eight to ten hours per week for one semester, with some time spent in the laboratory and some spent in database searching, reading and writing the report. In completing their projects, students acquired a knowledge of Mendel’s first law (through looking at inheritance patterns), Mendel’s second law and the exceptions (the concepts of linkage and linkage disequilibrium), DNA structure (primer design and restriction enzyme analysis) and function (SNPs in coding and non-coding regions), population genetics and the statistical analysis of allele frequencies, genomics, bioinformatics and the ethical issues associated with the use of human samples. They also developed skills in presentation of results by publication and conference participation. Deficiencies in their understanding (for example of inheritance patterns, gene structure, statistical approaches and report writing) were detected and guidance given during the project. SNP analysis was found to be a powerful approach to enhance and integrate student understanding of genetic concepts.
