Australia\u27s solution to disability discrimination enforcement
[Excerpt] Until recently, Australian disability discrimination law was similar to that of the United States and much of the rest of the world: it defined disability relatively narrowly, its penalties for noncompliance were relatively paltry, and it depended on enforcement of lawsuits brought by aggrieved private citizens. In 2009, however, Australia adopted the Fair Work Act 2009 (FW Act). The FW Act defined disability much more broadly, increased substantially the penalties for noncompliance, and created a state institution to enforce disability rights. This article analyses the FW Act, compares it to the workplace disability law in the United States, and argues that the FW Act is a transformational development in the struggle to achieve workplace equality and is an approach that should attract significant international interest
Characterisation of dairy soiled water in a survey of 60 Irish dairy farms
peer-reviewedDairy farming in Ireland generates an effluent known as dairy soiled water (DSW), which consists of a relatively dilute mixture of cow faeces, urine, spilt milk and detergents that is typically applied to grassland. However, relatively little is known about the volumes generated, nutrient content and management factors that influence volume and concentration. Sixty dairy farms that had a separate storage tank for storing DSW were selected for this study. The spatial distribution of the farms reflected the spatial distribution of dairy cows across the 26 counties of the Republic of Ireland, with each farm representing between 10,000 and 20,000 dairy cows. Samples were analysed for biochemical oxygen demand (BOD), ammonium N (NH4-N), total nitrogen (TN), potassium (K), phosphorus (molybdate-reactive and total) (MRP and TP) and dry matter (DM) content. Management characteristics and parlour properties were quantified. Factors influencing volume and concentration of DSW were determined using mixed model multiple regression analysis. On average, 9784 l (standard error 209 l) of DSW, including rainfall, was produced cow−1 year−1 and this contained significant quantities of total N, P and K (587, 80 and 568 mg l−1, respectively). A typical Irish dairy farm stocked at 1.9 cows ha−1 could therefore supply approximately 13, 2 and 12 kg ha−1 of total N, P and K, respectively, across the farm, annually to meet some of the nutrient requirements for herbage production and potentially replace some of the synthetic fertilizer use. Seventy one percent of samples were within the regulated concentration limits of soiled water for BOD (<2500 mg l−1), rising to 87% during the closed period for slurry spreading (mid October to mid-late January), while 81% were within the concentration limits for DM (<1% DM), rising to 94% during the closed period. The efficiency of a milking parlour (cows per unit, time taken) plays a key role in determining the volume of DSW generated. This, in turn, also influences the concentration of nutrients and other chemicals. Large variability was found in nutrient concentrations and this presents a challenge for effective nutrient management to maximise the fertilizer replacement value of DSW
Estimating the relative rate of recombination to mutation in bacteria from single-locus variants using composite likelihood methods
A number of studies have suggested using comparisons between DNA sequences of
closely related bacterial isolates to estimate the relative rate of
recombination to mutation for that bacterial species. We consider such an
approach which uses single-locus variants: pairs of isolates whose DNA differ
at a single gene locus. One way of deriving point estimates for the relative
rate of recombination to mutation from such data is to use composite likelihood
methods. We extend recent work in this area so as to be able to construct
confidence intervals for our estimates, without needing to resort to
computationally-intensive bootstrap procedures, and to develop a test for
whether the relative rate varies across loci. Both our test and method for
constructing confidence intervals are obtained by modeling the dependence
structure in the data, and then applying asymptotic theory regarding the
distribution of estimators obtained using a composite likelihood. We applied
these methods to multi-locus sequence typing (MLST) data from eight bacteria,
finding strong evidence for considerable rate variation in three of these:

Essex County Council primary schools (1973-1993): a design appraisal
The thesis is an appraisal of various design aspects of new and extended primary schools in Essex built between 1973 and 1993.
The investigation method included a review of primary school design literature and County Council archives, interviews with Officers concerned with the design and operation of primary schools, visits to schools, analysis of user comment by questionnaire, and investigative essays.
The appraisal contains three parts:- part one a review of primary education since 1973; part two strategic aspects of primary school design, including, planning, constructional systems, aesthetics, environmental design, engineering services, interior and exterior design; part three detailed requirements of today's primary school room by room; plus conclusions promulgating lessons for the future.
Main conclusions of the study are :-
- Economic and political pressures have reduced quality and space standards, encouraged traditional teaching methods, and reduced community use.
- The County Architect and Education department's influence diminished as power was delegated to individual schools.
- Limited generic plans, including the paired classbase, have developed which are a useful precedent for future design teams.
- System building produced stereotype deep plan buildings, with austere architecture which failed to respect their setting or delight users. Current traditional pitched roof designs are more successful, but relatively uninspired.
- Despite environmental design and engineering attempting to balance conflicting factors and reduce energy consumption by using alternative fuels and solar passive methods, users prefer locally controlled traditional heating and ventilation systems.
- Interiors are high quality with a domestic ambience, whereas exteriors are poor quality with windswept wastelands without enclosure or facilities for outside teaching.
- Users believe 1980s schools are too small, sufficient classbase space is a priority, and demand better quality exteriors.
This thesis should provide a clear view of the clients' requirements, past precedent, and critical relationships and will help future multi-disciplinary design teams, working under difficult conditions, produce better primary schools for Essex
Automated Recognition of Brain Region Mentions in Neuroscience Literature
The ability to computationally extract mentions of neuroanatomical regions from the literature would assist linking to other entities within and outside of an article. Examples include extracting reports of connectivity or region-specific gene expression. To facilitate text mining of neuroscience literature we have created a corpus of manually annotated brain region mentions. The corpus contains 1,377 abstracts with 18,242 brain region annotations. Interannotator agreement was evaluated for a subset of the documents, and was 90.7% and 96.7% for strict and lenient matching respectively. We observed a large vocabulary of over 6,000 unique brain region terms and 17,000 words. For automatic extraction of brain region mentions we evaluated simple dictionary methods and complex natural language processing techniques. The dictionary methods based on neuroanatomical lexicons recalled 36% of the mentions with 57% precision. The best performance was achieved using a conditional random field (CRF) with a rich feature set. Features were based on morphological, lexical, syntactic and contextual information. The CRF recalled 76% of mentions at 81% precision, by counting partial matches recall and precision increase to 86% and 92% respectively. We suspect a large amount of error is due to coordinating conjunctions, previously unseen words and brain regions of less commonly studied organisms. We found context windows, lemmatization and abbreviation expansion to be the most informative techniques. The corpus is freely available at http://www.chibi.ubc.ca/WhiteText/
