title: Technological concepts and technical contexts for technology education

authors: Doyle, Andrew

abstract: The origins and trajectory of technology education in different national contexts has been well charted, and the Irish context mirrors the vocational past found in many countries around the world (Banks & Williams, 2022). While an in-depth discussion on this history is beyond the scope of this chapter, it is important to note. The relevance here stems from the clarity through which the content of these previous subject may be represented. As the primary focus was on the preparation of learners for the world or work, the skills, knowledge and competencies associated with wood- and graphical communication-oriented professions formed the primary content of subjects. With the development from vocationally oriented technical education, technology education is instead presented as a learning area of importance for all learners. While the goals for technology education are well articulated, and have been for some time, the perennial debate in technology education is the stymied transition from technical education. It is my contention that the technical contexts that defined vocational education, which are still present in curricular representations of technology education, contribute to these tensions.

title: Balanced diagonals in frequency squares

authors: Cavenagh, Nicholas J.

subjects: Science & Technology

abstract: We say that a diagonal in an array is λ-balanced if each entry occurs λ times. Let L be a frequency square of type F (n; λ); that is, an n ✕ n array in which each entry from {1, 2, …, m=n / λ } occurs  λ times per row and  λ times per column. We show that if m≤3 , L contains a λ -balanced diagonal, with only one exception up to equivalence when m=2. We give partial results for m≥4 and suggest a generalization of Ryser’s conjecture, that every Latin square of odd order has a transversal. Our method relies on first identifying a small substructure with the frequency square that facilitates the task of locating a balanced diagonal in the entire array.

title: Niupepa: A historical newspaper collection

authors: Apperley, Mark

abstract: Niupepa is a collection of 42 newspaper titles published in New Zealand from 1842-1933, comprising a total of 21,000 pages in 1,750 issues. This collection forms a unique historical record of the language of the indigenous Mãori people, the evolution of the written form of this language, and of events and developments during the formative colonial history of our country. Using the Greenstone software from the New Zealand Digital Library this collection is now publicly available with full-text search capability.
