title: Random Relational Rules

authors: Pfahringer, Bernhard

subjects: computer science

abstract: Exhaustive search in relational learning is generally infeasible, therefore some form of heuristic search is usually employed, such as in FOIL[1]. On the other hand, so-called stochastic discrimination provides a framework for combining arbitrary numbers of weak classifiers (in this case randomly generated relational rules) in a way where accuracy improves with additional rules, even after maximal accuracy on the training data has been reached. [2] The weak classifiers must have a slightly higher probability of covering instances of their target class than of other classes. As the rules are also independent and identically distributed, the Central Limit theorem applies and as the number of weak classifiers/rules grows, coverages for different classes resemble well-separated normal distributions. Stochastic discrimination is closely related to other ensemble methods like Bagging, Boosting, or Random forests, all of which have been tried in relational learning [3, 4, 5].

title: Sedimentation and survival of the Mekong Delta: A case study of decreased sediment supply and accelerating rates of relative sea level rise

authors: Allison, Mead A.

abstract: The Mekong Delta, early in the twenty-first century, is at a tipping point for sustainability. The delta is threatened by the implications of (1) damming and land-use changes in the drainage basin, (2) a burgeoning delta population in a nation (Vietnam) undergoing rapid development, (3) accelerating rates of rising sea level, and (4) an uncertain future climate that may impact tropical-cyclone frequency and monsoonal precipitation patterns in the basin. These threats are present in other great rivers that emerge from the Himalayas. Two primary threats are examined in light of recent joint Vietnam-US studies in the largest distributary (Song Hau) of the Mekong River, in the shore-fringing mangroves, and on the adjacent subaqueous delta. We consider the implications of declining sediment loads from the catchment (as well as modification of the annual hydrograph) and flooding and salinity intrusion associated with relative sea level rise (eustatic + subsidence). This 2014–2015 study shows the interconnectivity in fluvial sediment supply to these parts of the delta: declining sediment loads and rising sea levels will likely impact distributary channel morphology and will alter estuarine circulation and sediment-trapping efficiency, all of which have feedbacks on sediment provision to the mangrove forests and the shelf.

title: Drawing on linguistic concepts to teach te reo Māori; Drawing on te reo Māori to teach linguistic concepts

authors: Wessels, Kanauhea Janion

subjects: linguistic pedagogy

abstract: In this paper, we explore the intersections in our teaching practice between the discipline of linguistics and te reo Māori. From the perspective of language teaching, in pedagogic materials for te reo Māori, we have observed that linguistic concepts are not typically highlighted (cf. Moorfield 2001, Jacobs 2012). From the perspective of teaching linguistics, te reo Māori is seldom employed to illustrate or assess linguistic concepts, although it commonly features in accounts of language revitalization. Content that does occur is limited (cf. Burridge & Stebbins, 2016). 
As a tertiary lecturer of the Māori language, I (Kanauhea) consider how, in my teaching practice, I draw on my technical knowledge of linguistics to enhance my explanations of language structures and their functions, where these are unfamiliar to language learners. As a tertiary linguistics lecturer, I (Julie) consider ways in which I draw on my beginner knowledge of te reo Māori to enhance my teaching of linguistic concepts, reflecting on materials I have developed to teach and assess students. 
We argue that students of te reo can benefit from linguistic understandings on their language learning journeys. Equally, as Aotearoa New Zealand's indigenous language, te reo Māori should have a strong presence in linguistic teaching materials, and our linguistics students should graduate with an indepth knowledge of te reo Māori structures.
