title: Submerged Thin Plate Weirs With Unequal Upstream and Downstream Beds

authors: Nalder, Guinevere Vivianne

subjects: thin plate weirs

abstract: This thesis describes a short study to examine the behaviour of submerged flow over a thin plate weir with differing upstream and downstream bed levels i.e. an unequal bed weir as opposed to an equal bed weir where the upstream and downstream beds are at the same level.

As submerged weir flow is a function of downstream conditions, it was thought that a lower downstream bed would make submerged flow over the weir easier, This is turn suggested that;
 	The shape of the upstream head (Hu) vs downstream head (Hd) graph would change, being initially more steep in the unequal bed case.
 	The Froude Number of the approaching flow would be lower for the unequal bed weir than for an equal bed weir at the same submergence.
 	Using one of the existing submerged flow formula would lead to an erroneous calculated value.

A series of measurements was done on two model weirs of different sizes subject to successive levels of submergence. Analysis of the readings of upstream and downstream heads indicated that the difference in bed levels was significant and the three effects above were noted.

The work also suggested a new form of equation to calculate flow over a submerged weir. This was looked at briefly.

title: Assessing learning skills and work habits: What do report card data tell us?

authors: Merchant, Stefan Denis

subjects: learning skills

abstract: Many school systems ask teachers to assess and report upon aspects of student performance beyond academic achievement. In Ontario, K–12 teachers assess a common set of six Learning Skills and Work Habits. How well teachers are able to undertake these assessments is not well studied. This study examines Grade 9 and 12 report card data from two districts in Ontario, Canada to determine to what extent different learning skills are assessed independently of each other, and to what extent they are associated with teacher-awarded academic achievement and achievement on a standardized Grade 9 mathematics examination delivered by Ontario’s Educational Quality and Accountability Office (EQAO). Results indicate that the set of six Learning Skills and Work Habits are assessed as a unitary construct. Grades on these skills have higher correlations with teacher-awarded grades than with standardized test scores. Finally, gender differences in both academic achievement and achievement on the set of skills are investigated.

title: The Treaty of Waitangi and Research Ethics in Aotearoa

authors: Hudson, Maui

subjects: Treaty of Waitangi

abstract: Researchers, when engaging with Māori communities, are in a process of relationship building and this process can be guided by the principles of the Treaty of Waitangi, partnership, participation and protection. The main concerns for many indigenous peoples in research revolve around respect for their indigenous rights, control over research processes and reciprocity within research relationships to ensure that equitable benefits are realised within indigenous groups. Māori have identified similar issues and these concerns can be aligned with the principles of the Treaty of Waitangi. The relevance of the Treaty of Waitangi to research ethics is discussed and this paper suggests a revised interpretation of the treaty principles to incorporate the range of ethical issues that Māori have expressed as important.
