title: Balancing openness with Indigenous data sovereignty: An opportunity to leave no one behind in the journey to sequence all of life

authors: Cartney, Ann M. Mc

abstract: The field of genomics has benefited greatly from its "openness" approach to data sharing. However, with the increasing volume of sequence information being created and stored and the growing number of international genomics efforts, the equity of openness is under question. The United Nations Convention of Biodiversity aims to develop and adopt a standard policy on access and benefit-sharing for sequence information across signatory parties. This standardization will have profound implications on genomics research, requiring a new definition of open data sharing. The redefinition of openness is not unwarranted, as its limitations have unintentionally introduced barriers of engagement to some, including Indigenous Peoples. This commentary provides an insight into the key challenges of openness faced by the researchers who aspire to protect and conserve global biodiversity, including Indigenous flora and fauna, and presents immediate, practical solutions that, if implemented, will equip the genomics community with both the diversity and inclusivity required to respectfully protect global biodiversity.

title: Beyond structuralism: Exploring a semantic based approach for describing the Māori language in grammar books and textbooks for pedagogical purposes

authors: Taiapa, Michael William

subjects: Māori

abstract: Since the 1950s, the advancements and developments in English language studies has had a profound impact on its description that has made it less syntactically driven and more communicatively oriented. This has the potential to influence language description moving it from a purely structurally focused orientation to a more semantically focused one that could influence pedagogic outcomes in more meaningful and useful ways. Nevertheless, in the case of the Māori language, its description has largely focused on structure linguistics that was prevalent in the 19th and early 20th centuries. There has been very little focus on a semantic description and this, in turn, is reflected in grammar books and textbooks on te reo. This thesis set out to explore a semantic approach to describe te reo and to rethink how this type of description may be realized and included in the design of grammar books and textbooks for the teaching and learning of te reo in the broader field of second language pedagogy and acquisition. The thesis also includes a practical component in which a small sample of Māori language teachers were interviewed to determine how linguistic and/ or semantic approaches to describe te reo may have or have impacted on their own beliefs, attitudes, and teaching practices (See, Chapter 7). Thus, it is argued here that research-based studies, advancements, and developments in language descriptions over the past five decades (See, for example, Council of Europe, 1949; Fillmore, 1967; Longacre, 1968; & Crombie, 1985b) should play central roles in the design of a semantic based description of the Māori language from which a linguistic based description can significantly benefit.

title: Investigation into strain propagation to determine preserve regions for compliant mechanisms

authors: Venter, Christoff

subjects: compliant mechanisms

abstract: This thesis aims to improve the theoretical modelling of compliant mechanisms. The
conclusions drawn from this work will help designers understand sources of error associated
with strain propagation when designing with lumped compliance. Compliant mechanisms
have increased in popularity as they allow for designs that feature lower part counts,
increased precision and reduced manufacturing costs. Although using theoretical models
to design compliant mechanisms is a useful tool, there is an assumption that only the
nodes in a compliant mechanism undergo strain. This is not the case. There is strain
occurring outside of the node in a region called the preserve region. The preserve region’s
impact on the theory is greatly under-explored in the literature.
The preserve region’s size, shape, and impact were found and quantified for a range
of critical node types. This was done through the use of FEA software by altering the
model of a simple, compliant mechanism. The size of the preserve region changed based
on the thickness and the fillet used, with an increase of thickness from 4mm to 8mm,
causing the radius of the arc that encompasses the preserve region to grow from 8.5mm to
13mm. The shape was also found to be an ellipse, irrespective of the node’s geometry. The
preserve region’s impact on the theoretical models was also quantified. It was found that
the thickness has the most drastic effect on the compliance values of the node, increasing
the error from 20.53% to 102.18% when the thickness was increased from 4mm to 8mm.
This work shows the importance of considering the preserve region when creating
theoretical models of compliant mechanisms. When properly considered, this research
shows that the error between the theoretical and the FEA values can be greatly reduced.
