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: A new Geographic Profiling Suspect Mapping And Ranking Technique for crime investigations: GP-SMART

authors: Curtis-Ham, Sophie

abstract: This study developed and tested a new geographic profiling method for automating suspect prioritisation in crime investigations. The Geographic Profiling Suspect Mapping And Ranking Technique (GP-SMART) maps suspects' activity locations available in police records—such as home addresses, family members' home addresses, prior offence locations, locations of non-crime incidents, and other contacts with police—and ranks suspects based on both the proximity and nature of these locations, relative to an input crime. In accuracy tests using solved burglary, robbery and extra-familial sex offence cases in New Zealand (n = 4511), GP-SMART ranked the offender at or near the top of the suspect list at rates greatly exceeding chance. Highlighting the benefit of its novel inclusion and differentiation of many different types of activity location, GP-SMART also outperformed baseline methods—approximating existing algorithms—that ranked suspects using only the proximity of their activity locations, or home addresses, to the input crime.

title: The Māori language curriculum for New Zealand schools: Spiral lesson/ lesson sequence design

authors: Johnson, Diane

subjects: Māori language teaching

abstract: A draft curriculum document for the teaching and learning of te reo Māori as a subject in mainstream schools in New Zealand (that is, in schools other than Kura Kaupapa Māori schools) was designed and trialled in 2004 and 2005. That draft is currently being reworked in line with the advice of those who trialled the document as well as that of a team of advisers set up by the Ministry of Education. The revised curriculum document will be submitted to the Ministry of Education in May 2006. As is the case with all new curriculum documents, the implementation phase will be critical. The extent to which this flexible, outcomes-focused curriculum document will genuinely inform new approaches to teaching and learning will depend not only upon the good will of teachers and communities, but also upon their ability to interpret the curriculum and to use it in a way that informs the design of language programmes, including the planning of units of work and of lessons and lesson sequences. In balancing language development and language practice, a communicative core and spiral approach is recommended, an approach in which there are core lessons (where the focus is language development) and spiral lessons (where the focus is language practice). In an earlier issue of this Journal (Johnson, 2003), one of us discussed core lesson design. Here, the design of spiral lessons is discussed and exemplified in the context of an outcomes-based curriculum.
