Using Spatial Systems to Establish Priorities for Catchment Management

Priorities for catchment management can be established based on either, an objective assessment of relative priorities throughout the catchment, or by simply responding to crises associated with particular land uses and their sectional interests. While the latter method can have advantages in terms of establishing community good will, team cohesion, and a sense of achievement for particular sectional interests, it may have shortcomings in terms of a more objective and rational assessment of the relative magnitude and hence priority of land management problems. Spatial modelling using GIS can form the basis for developing a catchment-wide understanding of the relative importance of land management problems. Spatial models have been successfully used to estimate water and pollution generation rates internationally, and to identify phosphorus-loss hot-spots in the Leschenault and Swan catchments locally. Land capability assessment, based on soil and landform information, has been well established as a basis for defining, together with an assessment of planning considerations such as demand, infrastructure and services, the suitability of the land for particular land uses. Land capability information can also be used to prioritise and target catchment management activities. Situations where land management practices need to be improved can be readily identified by combining current land use information, land capability information and the results of spatial models describing water, nutrient, sediment or salt generation using GIS. For example, an intersection between existing landuse, land capability and a nutrient generation model would flag annual horticulture as being inappropriate on leaching sands adjacent to fragile wetlands. Such an intersection would not flag this particular landuse where it had been established at a site with a higher land capability rating. These types of intersections can also help identify priority areas for rehabilitation or conservation of riparian corridors. An example of the use of these types of intersections in catchment management prioritisation is presented

Taking reincarnation seriously: Critical discussion of some central ideas from John Hick

Reincarnation has not been entirely neglected in the philosophy of religion but it has not always been taken seriously or carefully discussed in relation to its role in believers’ lives. John Hick is exceptional insofar as he gave sustained attention to the belief, at least as it features in the philosophies of Vedānta and Buddhism. While acknowledging the value of Hick’s recognition of the variety of reincarnation beliefs, this article critically engages with certain aspects of his approach. It argues that Hick’s search for a ‘criterion’ of reincarnation is misguided, and that his distinction between ‘factual’ and ‘mythic’ forms of the doctrine is over-simplifying

Database Engineering Processes with DB-MAIN

Software engineering needs more and more to be supported by CASE tools. Since databases are at the heart of information systems, they deserve a particular attention. More and more CASE tools allow method engineers to implement their own methodology and they allow users to record all their actions, with their rationales, in order to improve the quality of the design and the quality of the documentation of the design. DBMAIN is such a database oriented tool with a method description and a documentation generation facilities. But it has its particularities like its procedural non-deterministic Method Description Language, its well integrated multilevel histories and its userfriendly methodological engine

Thermalization of magnons in yttrium-iron garnet: nonequilibrium functional renormalization group approach

Using a nonequilibrium functional renormalization group (FRG) approach we calculate the time evolution of the momentum distribution of a magnon gas in contact with a thermal phonon bath. As a cutoff for the FRG procedure we use a hybridization parameter {\Lambda} giving rise to an artificial damping of the phonons. Within our truncation of the FRG flow equations the time evolution of the magnon distribution is obtained from a rate equation involving cutoff-dependent nonequilibrium self-energies, which in turn satisfy FRG flow equations depending on cutoff-dependent transition rates. Our approach goes beyond the Born collision approximation and takes the feedback of the magnons on the phonons into account. We use our method to calculate the thermalization of a quasi two-dimensional magnon gas in the magnetic insulator yttrium-iron garnet after a highly excited initial state has been generated by an external microwave field. We obtain good agreement with recent experiments.Comment: 16 pages, 6 figures, final versio

Hick and Radhakrishnan on Religious Diversity: Back to the Kantian Noumenon

We shall examine some conceptual tensions in Hick’s ‘pluralism’ in the light of S. Radhakrishnan’s reformulation of classical Advaita. Hick himself often quoted Radhakrishnan’s translations from the Hindu scriptures in support of his own claims about divine ineffability, transformative experience and religious pluralism. However, while Hick developed these themes partly through an adaptation of Kantian epistemology, Radhakrishnan derived them ultimately from Śaṁkara (c.800 CE), and these two distinctive points of origin lead to somewhat different types of reconstruction of the diversity of world religions. Our argument will highlight the point that Radhakrishnan is not a ‘pluralist’ in terms of Hick’s understanding of the Real. The Advaitin ultimate, while it too like Hick’s Real cannot be encapsulated by human categories, is, however, not strongly ineffable, because some substantive descriptions, according to the Advaitic tradition, are more accurate than others. Our comparative analysis will reveal that they differ because they are located in two somewhat divergent metaphysical schemes. In turn, we will be able to revisit, through this dialogue between Hick and Radhakrishnan, the intensely vexed question of whether Hick’s version of pluralism is in fact a form of covert exclusivism.This is the author accepted manuscript.

3-D reconstructions of the early-November 2004 CDAW geomagnetic storms: analysis of Ooty IPS speed and density data

Interplanetary scintillation (IPS) remote-sensing observations provide a view of the solar wind covering a wide range of heliographic latitudes and heliocentric distances from the Sun between ~0.1 AU and 3.0 AU. Such observations are used to study the development of solar coronal transients and the solar wind while propagating out through interplanetary space. They can also be used to measure the inner-heliospheric response to the passage of coronal mass ejections (CMEs) and co-rotating heliospheric structures. IPS observations can, in general, provide a speed estimate of the heliospheric material crossing the observing line of site; some radio antennas/arrays can also provide a radio scintillation level. We use a three-dimensional (3-D) reconstruction technique which obtains perspective views from outward-flowing solar wind and co-rotating structure as observed from Earth by iteratively fitting a kinematic solar wind model to these data. Using this 3-D modelling technique, we are able to reconstruct the velocity and density of CMEs as they travel through interplanetary space. For the time-dependent model used here with IPS data taken from the Ootacamund (Ooty) Radio Telescope (ORT) in India, the digital resolution of the tomography is 10° by 10° in both latitude and longitude with a half-day time cadence. Typically however, the resolutions range from 10° to 20° in latitude and longitude, with a half- to one-day time cadence for IPS data dependant upon how much data are used as input to the tomography. We compare reconstructed structures during early-November 2004 with in-situ measurements from the Wind spacecraft orbiting the Sun-Earth L<sub>1</sub>-Point to validate the 3-D tomographic reconstruction results and comment on how these improve upon prior reconstructions
