title: Quantitative landslide susceptibility assessment of the Waikato region using GIS

authors: Schicker, Renee Deborah

subjects: landslide

abstract: Areas that have experienced landslide events in the past and the conditioning factors present at these sites can be used to identify areas of the same or similar susceptibility. This can be achieved through a landslide susceptibility assessment using a landslide inventory, a set of predictor variables and specialised computer software.
A quantitative landslide susceptibility assessment was conducted for the Waikato Region using two statistical approaches and eleven predictor variables. A landslide inventory map was constructed from the GNS QMap landslide spatial data and GeoNet landslide catalogue. Parameter maps for slope, elevation, aspect, lithology, land cover, soil order, mean monthly rainfall, maximum monthly rainfall, distance from roads, distance from faults and distance from rivers, were constructed and compiled into a database with the landslide inventory. 
The compiled data underwent both bivariate (weights of evidence) and multivariate (logistic regression) statistical analysis, and a landslide susceptibility map was derived for each. In the weights of evidence approach, the presence and absence of each class in relation to landslide occurrence and non-occurrence was individually assessed for each predictive factor. Logistic regression involves fitting a generalised non-linear model to the data based on a binary predictor (presence or absence of a past landslide event). For each method, a landslide susceptibility map was derived, and the model fit assessed using the landslide inventory.
Both susceptibility maps underwent an evaluation to determine the better predictive model. An independent landslide data set was compiled from observations made in Google Earth, and used to establish a set of prediction rate curves and cumulative area curves. Both susceptibility maps resulted in very similar prediction rate curves. Weights of evidence gave a better prediction rate in the 10, 20 and 30% most susceptible pixels, but not in the 40% most susceptible pixels. Neither susceptibility map could be justified as being better than the other based on the prediction rate curves alone. The cumulative area curves for each susceptibility map resulted in very different outcomes. Logistic regression gave the best result with a large proportion of the landslide area within a small proportion of the total area in the high susceptibility classes. Weights of evidence had a larger proportion of the landslide area in high susceptibility classes than logistic regression, but this was associated with a large proportion of total area. Based on the evaluation, the susceptibility map derived using logistic regression was determined to be superior.

title: Requirements on dance-driven 3-D camera interaction: A collaboration between dance, Graphic Design and Computer Science

authors: Jung, Doris

subjects: computer science

abstract: In this paper we describe our initial ideas towards research investigating dance-driven 3-D-camera interaction as a tool for creating holistic pieces of art for an enriched performance experience.
In the first part, we focus on the technical analysis of requirements on a set of input parameters for the dance input.
In the second part we explore requirements stemming from the creative themes envisaged.
In the discussion we synergize these requirements towards the requirements on a first prototype of the dance-driven 3-D-camera interaction.

title: Faith, politics and reconciliation: the Roman Catholic Church, New Zealand Maori and indigenous Australians

authors: O'Sullivan, Dominic

abstract: The Roman Catholic Church claims from Jesus Christ a mission to teach consistently religious ideals in accordance with its understanding of God’s constant truth. These ideals include the belief that human creation in the image and likeness of God establishes rights to dignity, to culture, to religious freedom, to self-determination and a share in the common good. These ideals form the basis of the unique contribution to human affairs which the Church claims it can make. Although these are religious goals for the Church, they require political realisation, which means that the Church cannot but be alert to the formation of alliances of common intellectual aspiration around concrete political issues so that secular expression and context can be given to the magisterium (the Church’s body of teaching). At the same time the Catholic hierarchy is conscious of a need for caution in how it responds to political events lest that religious mission be compromised by a perception of it as a partisan political lobby group, thus lessening its capacity to make its unique contribution to human affairs. 

The Second Vatican Council reaffirmed that the Church’s religious objectives do not exist in isolation from the political order because human law, which is developed through the secular political process, should conform to the religious natural law. Prior to the Council’s reaffirmation the Australian and New Zealand Churches generally, but not exclusively, understated or misunderstood this relationship and became impotent in challenging secular objectives inconsistent with religious aspiration. In contrast when the Church has accepted the relationship, as it has since the Second Vatican Council, it has positioned itself to identify opportunities to give secular context and expression to religious thought. Such opportunities increased from the 1960s onwards as political developments in both Australia and New Zealand saw a secular questioning of racism and a broadening of the parameters of secular political debate to the extent that established Catholic thought was shifted from the fringes to the widening mainstream of public opinion on indigenous policy. 

Although the Second Vatican Council required attention to the relationship between religious ends and political means, the changing secular environment was a significant factor in encouraging public advocacy in support of indigenous aspiration, which peaked in Australia in the 1990s with substantial Church interest in the native title debate and with the Church playing a leading role in the entrenchment of reconciliation - a religious concept - on the Australian political landscape. In New Zealand there has been an equal but less vocal interest in reconciliation because the political process itself established the Treaty of Waitangi as a political context for reconciliation and a context around which the Church has been able to focus its interest in the advancement of Maori aspiration. Yet, while the Treaty of Waitangi and the associated bicultural discourse have provided contexts for the expression of religious principle, they have also detracted from the Church’s use of its own magisterium as the moral authority for the articulation of its aspirations for Maori.
