title: Modeling the effects of aerial temperature and exposure period on intertidal mudflat profiles

authors: Nguyen, Hieu M.

abstract: This research demonstrates how the effect of exposure to air on intertidal flat profile development in cohesive coastal environments can be incorporated into applied numerical modelling. Semi-empirical relationships were used to include the sediment stabilizing effects of exposure on changes to the erosion threshold (Ƭcr; N m−2) and erosion rate (ER; g m−2 s−1) during low tide, which also consider the effect of air temperature, T (°C) and exposure duration, D (h). The relationships were based on fundamental forms of the theoretical relationship between water content and evaporation rate, and were fitted to empirical data. Changes were incorporated into the Delft3D model, and scenarios monitored bed level profile development over an annual time scale with different T, sediment stabilizing biofilm biomass (using Chl-a content as a proxy), initial bed composition (mud/sand percentage), and spring and neap tides (regulating current velocity and exposure duration). Model results indicated that the stabilizing effect of exposure will lead to a more flat-topped shape of intertidal mudflats, implying that bed level changes caused by exposure occur lower on intertidal flats compared to runs with no exposure. Higher air temperatures had a greater effect on bed level change, with the maximum accretion of up to 0.039 m (290% higher) occurring in the case of 40 °C compared with the case of no exposure effect with 0.01 m of accretion. Research findings can contribute to understanding of how intertidal flats evolve and is critical to predicting the resilience of these habitats to sea-level rise and warming temperatures.

title: An analysis of cooking queries: Implications for supporting leisure cooking

authors: Cunningham, Sally Jo

subjects: computer science

abstract: Cooking is a common and an information-intensive activity. We analyze a set of 678 cooking-related queries to identify the attributes that cooks provide in their queries to the Google AnswersTM ‘ask an expert’ online reference system. The results suggest directions to take in developing an effective organization and improved functionality for a cooking-focused digital library.

title: Monitoring first year Maori students enrolled in selected Faculty of Arts and Social Sciences courses: A report prepared for the Dean of the Faculty of Arts and Social Sciences

authors: Levy, Michelle Patricia

subjects: maori students

abstract: Monitoring first year Maori Students Enrolled in Selected Faculty of Arts andSocial Sciences Courses. The total number of Maori students targeted by this project was 182, representing 93% of the total number of Maori students enrolled in Semester B level one courses. The majority of students participating in this initiative were first year students, although a small number of students taking 100 level courses were second, third or graduate year students. 11 Student views on the monitoring and support initiative Students were provided with the opportunity to comment on the monitoring and support initiative. All students contacted (49) recommended that this intervention continue for future first year Maori students enrolled in FASS.
