title: Genetic identification of fish

authors: Banks, Jonathan C.

subjects: DNA barcoding

abstract: Our report shows that the straightforward extraction of DNA and amplification of appropriate genes can identify fish that are difficult to identify unequivocally from morphology alone.  Three examples show that these techniques can be extended to identify fish from other regions or countries and could be useful for the surveillance of illegal or unregulated transfers of fish, and for identifying species from a conservation perspective.

title: The architecture of an optimistic CPU: the WarpEngine

authors: Cleary, John G.

subjects: computer science

abstract: The architecture for an optimistic, highly parallel, scalable, shared memory CPU - the WarpEngine - is described. The WarpEngine CPU allows for parallelism down to the level of single instructions and is tolerant of memory latency. Its design is based around time stamping executable instructions and all memory accesses. The TimeWarp algorithm [Jefferson 1985, 1989] is used for managing the time stamps and synchronisation. This algorithm is optimistic and requires that all computations can be rolled back. The basic functions required for implementing the control and memory system used by TimeWarp are described. The WarpEngine memory model presented to the programmer, is a single linear address space which is modified by a single thread of execution. Thus, at the software level there is no need for locks or other explicit synchronising actions when accessing the memory. The actual physical implementation, however, is multiple CPUs with their own caches and local memory with each CPU simultaneously executing multiple threads of control. Reads from memory are optimistic, that is, if there is a local copy of a memory location it is taken as the current value. However, sometimes there will be a write with an earlier time stamp in transit in the system. When it arrives it causes the original read and any dependent calculations to be re-executed.

title: Whāia ngā pae o te māramatanga: our horizons of pursuit

authors: Ruru, Jacinta

abstract: In Aotearoa New Zealand there is a growing recognition that Māori engagement and leadership across the science and research sector is essential for addressing national challenges and realising the distinctive contribution of mātauranga Māori to innovation and knowledge creation (Ministry of Education 2013a). To reap the benefits of the nation’s changing demographics and to centre Te Tiriti o Waitangi in society, it is critical that Māori are engaged in research and decision making in all disciplines and in all sectors. This article considers how Ngā Pae o te Māramatanga (NPM), New Zealand’s Māori Centre of Research Excellence, is contributing towards addressing and developing challenges and opportunities at the interface between mātauranga Māori and science. The article traces the contribution of NPM as a positive transformative contributor to research in Aotearoa New Zealand and internationally
