Summary of ARATA\u27s key recommendations arising from the Discussion Paper:
1. Evaluate outcomes from AT provision in trial sites and other systems to inform in the development of procurement and service delivery policy, consumer supports, and continuing professional development.
2. Support practitioners and researchers to validate existing AT service models for use in Australia.
3. Assist ARATA and other key stakeholders to develop a national accreditation system for AT practitioners and suppliers.
4. Investigate and document the roles, activities, and scope of practice of suppliers and peer mentors in AT service delivery, and associated outcomes for AT users.
5. Ensure the coupling of AT devices with appropriate soft technology support for device selection, implementation and review.
6. Investigate the efficacy and potential expansion of existing peer and consumer networking channels.
7. Support research into consumer use of information and decision-making in AT provision.
8. Fund independent AT information services and explore options for facilitating consumer ratings of products and services.
9. Identify AT products not yet available on the Australian market.
10. Fund research into AT development and commercialisation in Australia. 
Movement Behaviour of Traditionally Managed Cattle in the Eastern Province of Zambia Captured Using Two-Dimensional Motion Sensors
No full textTwo-dimensional motion sensors use electronic accelerometers to record the lying, standing and walking activity of cattle. Movement behaviour data collected automatically using these sensors over prolonged periods of time could be of use to stakeholders making management and disease control decisions in rural sub-Saharan Africa leading to potential improvements in animal health and production. Motion sensors were used in this study with the aim of monitoring and quantifying the movement behaviour of traditionally managed Angoni cattle in Petauke District in the Eastern Province of Zambia. This study was designed to assess whether motion sensors were suitable for use on traditionally managed cattle in two veterinary camps in Petauke District in the Eastern Province of Zambia. In each veterinary camp, twenty cattle were selected for study. Each animal had a motion sensor placed on its hind leg to continuously measure and record its movement behaviour over a two week period. Analysing the sensor data using principal components analysis (PCA) revealed that the majority of variability in behaviour among studied cattle could be attributed to their behaviour at night and in the morning. The behaviour at night was markedly different between veterinary camps; while differences in the morning appeared to reflect varying behaviour across all animals. The study results validate the use of such motion sensors in the chosen setting and highlight the importance of appropriate data summarisation techniques to adequately describe and compare animal movement behaviours if association to other factors, such as location, breed or health status are to be assessed.</p
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

Abstract
PURPOSE: To evaluate the role of topical mitomycin C in corneal wound healing (CWH) after photorefractive keratectomy (PRK) in highly myopic eyes.
DESIGN: Prospective, double-masked, randomized clinical trial.
PARTICIPANTS: Seventy-two eyes of 36 patients affected by high (>7 diopters) myopia.
METHODS: In each patient, one eye was randomly assigned to PRK with intraoperative topical 0.02% mitomycin C application, and the fellow eye was treated with a placebo. Postoperatively, mitomycin C-treated eyes received artificial tears (3 times daily, tapered in 3 months), whereas the fellow eye was treated with fluorometholone sodium 2% and artificial tears (3 times daily, tapered in 3 months).
MAIN OUTCOME MEASURES: Uncorrected visual acuity (UCVA) and best-corrected visual acuity (BCVA), contrast sensitivity, manifest refraction, and biomicroscopy. Contrast sensitivity was determined using the Pelli-Robson chart. Corneal confocal microscopy documented CWH.
RESULTS: Mean follow-up was 18 months (range, 12-36). No side effects or toxic effects were documented. At 12-month follow-up examination, UCVAs (logarithm of the minimum angle of resolution) were 0.4+/-0.48 and 0.5+/-0.53 (P = .03) in mitomycin C-treated eyes and corticosteroid-treated eyes, respectively. At 1 year, corneal haze developed in 20% of corticosteroid-treated eyes, versus 0% of mitomycin C-treated eyes. At 12, 24, and 36 months, corneal confocal microscopy showed activated keratocytes and extracellular matrix significantly more evident in untreated eyes (Ps = 0.004, 0.024, and 0.046, respectively).
CONCLUSION: Topical intraoperative application of 0.02% mitomycin C can reduce haze formation in highly myopic eyes undergoing PRK.

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
I flussi giudiziari: metodi di rilevazione, impieghi e prospettive
No full textNegli ultimi anni i temi della misurazione e del monitoraggio dei flussi giudiziari hanno attratto attenzione crescente da parte dei professionisti del Diritto, e portato alla creazione di un ampio dibattito specialistico- come testimoniato anche dall’esistenza di spazi virtuali di discussione su tali argomenti. La Sezione denominata “Dibattito” esamina tali temi attraverso la proposizione di: (a) una sintesi delle tematiche discusse nella mailing list; (b) il report relativo all’incontro svolto a Roma, il 4 Febbraio 2006, proprio sul tema dei flussi giudiziari; (c) tre interviste sull’argomento rispettivamente ad un giudice, un dirigente amministrativo, un avvocato
Can public policies tackle the phosphorus paradox in pig farming? The case of Po-valley and Lower Saxony
No full textP management in agriculture is raising the attention of policy makers
as well as of researchers. While the former aims at designing proper P
related policy measures to restrict the P load into water, the second
search for technical innovation to increase the efficiency of use of P
contained in the livestock diet. Our research aims at analysing the
impact of two P-related policies, limiting the P surplus application to 0
kg P/ha/year and to 4.35 kg P/ha/year respectively, on farmers’ technical
decisions and on their gross margin. We focus on pig fattening
farms in two highly dense livestock regions, Po-valley in Italy and Lower
Saxony in Germany, and simulate alternative strategies the farm can
adopt to comply with the two policies
A Multi-Language Comparison of Influences on Author Verification using Character N-Grams
No full textWe create a new multi-language corpus for author verification based on Wikipedia talkpages, and evaluate the influence that differences in topic and time have on character n-gram author profiles. Topic alignment between two texts is found to increase author verification precision, and an authors writing style is found to change over time, but not more significantly after 3 years than after 1 year.Information ArchitectureWISElectrical Engineering, Mathematics and Computer Scienc
