Funding special education provision by means of discriminant function analysis

This thesis is concerned with the development of a funding mechanism, the Student Resource Index, which has been designed to resolve a number of difficulties which emerged following the introduction of integration or inclusion as an alternative means of providing educational support to students with disabilities in the Australian State of Victoria. Prior to 1984, the year in which the major integration or inclusion initiatives were introduced, the great majority of students with disabilities were educated in segregated special schools, however, by 1992 the integration initiatives had been successful in including within regular classes approximately half of the students in receipt of additional educational assistance on the basis of disability. The success of the integration program brought with it a number of administrative and financial problems which were the subject of three government enquiries. Central to these difficulties was the development of a dual system of special education provision. On one hand, additional resources were provided for the students attending segregated special schools by means of weighted student ratios, with one teacher being provided for each six students attending a special school. On the other hand, the requirements of individual students integrated into regular schools were assessed by school-based committees on the basis of their perceived extra educational needs. The major criticism of this dual system of special education funding was that it created inequities in the distribution of resources both between the systems and also within the systems. For example, three students with equivalent needs, one of whom attended a special school and two of whom attended different regular schools could each be funded at substantially differing levels. The solution to these inequities of funding was seen to be in the development of a needs based funding device which encompassed all students in receipt of additional disability related educational support. The Student Resource Index developed in this thesis is a set of behavioural descriptors designed to assess degree of additional educational need across a number of disability domains. These domains include hearing, vision, communication, health, co-ordination (manual and mobility), intellectual capacity and behaviour. The completed Student Resource Index provides a profile of the students’ needs across all of these domains and as such addresses the multiple nature of many disabling conditions. The Student Resource Index was validated in terms of its capacity to predict the ‘known’ membership or the type of special school which some 1200 students in the sample currently attended. The decision to use the existing special school populations as the criterion against which the Student Resource Index was validated was based on the premise that the differing resource levels of these schools had been historically determined by expert opinion, industrial negotiation and reference to other special education systems as the most reliable estimate of the enrolled students’ needs. When discriminant function analysis was applied to some 178 students attending one school for students with mild intellectual disability and one facility for students with moderate to severe intellectual disability the Student Resource Index was successful in predicting the student's known school in 92 percent of cases. An analysis of those students (8 percent) which the Student Resource Index had failed to predict their known school enrolment revealed that 13 students had, for a variety of reasons, been inappropriately placed in these settings. When these students were removed from the sample the predictive accuracy of the Student Resource Index was raised to 96 percent of the sample. By comparison the domains of the Vineland Adaptive Behaviour Scale accurately predicted known enrolments of 76 percent of the sample. By way of replication discriminant function analysis was then applied to the Student Resource Index profiles of 518 students attending Day Special Schools (Mild Intellectual Disability) and 287 students attending Special Developmental Schools (Moderate to Severe Intellectual Disability). In this case, the Student Resource Index profiles were successful in predicting the known enrolments of 85 percent of students. When a third group was added, 147 students attending Day Special Schools for students with physical disabilities, the Student Resource Index predicted known enrolments in 80 percent of cases. The addition of a fourth group of 116 students attending Day Special Schools (Hearing Impaired) to the discriminant analysis led to a small reduction in predictive accuracy from 80 percent to 78 percent of the sample. A final analysis which included students attending a School for the Deaf-Blind, a Hospital School and a Social and Behavioural Unit was successful in predicting known enrolments in 71 percent of the 1114 students in the sample. For reasons which are expanded upon within the thesis it was concluded that the Student Resource Index when used in conjunction with discriminant function analysis was capable of isolating four distinct groups on the basis of their additional educational needs. If the historically determined and varied funding levels provided to these groups, inherent in the cash equivalent of the staffing ratios of Day Special Schools (Mild Intellectual Disability), Special Development Schools (Moderate to Severe Intellectual Disability), Day Special Schools (Physical Disability) and Day Special Schools (Hearing Impairment) are accepted as reasonable reflections of these students’ needs these funding levels can be translated into funding bands. These funding bands can then be applied to students in segregated or inclusive placements. The thesis demonstrates that a new applicant for funding can be introduced into the existing data base and by the use of discriminant function analysis be allocated to one of the four groups. The analysis is in effect saying that this new student’s profile of educational needs has more in common with Group A than with the members of Groups B, C, or D. The student would then be funded at Group A level. It is immaterial from a funding point of view whether the student decides to attend a segregated or inclusive setting. The thesis then examines the impact of the introduction of Student Resource Index based funding upon the current funding of the special schools in one of the major metropolitan regions. Overall, such an initiative would lead to a reduction of 1.54 percent of the total funding accruing to the region’s special schools.

Welcome 2 my deaf world

Presents the story of two students at the Victorian College for the Deaf (VCD). They are Bethany Rose and Scott Masterson, two ordinary teenagers, who live in the extraordinary world of the deaf. But, to both, it is a world of rich culture, full of human possibility. It has its own language, Auslan, with its own rules, challenges and inspirations. It is a culture which very few people know or fully understand. This documentary gives footage of the last few months of Bethany and Scott's schooling at the college. These teenagers have dreams of success in life, and are eager to enter the wider world. The Victorian College for the Deaf is the first school for deaf kids, as well as being the only school in Australia where the Australian sign language (Auslan) is used from Prep to Year 12, helping its students prepare for life in the adult world.

Effectiveness of recording in primary science : a study of the ability of junior primary school pupils to use drawing as an effective method of communication in science lessons

Drawing as a means of recording is a very common practice in junior primary science lessons. This is largely due to the availability of necessary materials. Also, most youg children have some degree of drawing skill and enjoy drawing activities. Since 1956 the science curriculum to be implemented in primary classrooms in Victoria has changed from one that was based largely on nature study (biological) to one that includes physical and technological aspects. Further, there have been changes in the teaching methodologies advocated for use in science lessons. A modified Interactive Teaching Approach was used for the studies. Drawing was the main means by which the children recorded information. The topic of 'shells' was used to enable collection of data about the children's enjoyment of the activity and satisfaction with their achievement. This study was replicated using the topic 'rocks'; again data were collected concerning satisfaction and enjoyment. During a series of lessons on 'snails' data were collected concerning the achievement of 'process' and 'objective' purposes that teachers might have in mind when setting a drawing activity. In addition to providing data about purposes the study stimulated some questions regarding the techniques the children had used in their drawings. Accordingly, data concerning the use of graphic techniques by the children were collected during a series of lessons on 'oils'. The data collected and analysed in the various studies highlighted the value of drawing in junior primary school science lessons. It also validated strategies developed by the author and designed to help teachers and children use drawing effectively in science activities.

After Charlie: free speech and the political economy of communication

Three significant events at the start of 2015 have put freedom of speech firmly on the global agenda. The first was the carry-over from the December 2014 illegal entry to the Sony Corporation’s file servers by anonymous hackers, believed to be linked to the North Korean regime. The second was the horrible attack on journalists, editors, and cartoonists at the French satirical magazine, Charlie Hebdo on 7 January. The third was the election of leftwing anti-austerity party Syrzia in Greece on 25 January.While each event is different in scope and size, they are important to scholars of the political economy of communication because they all speak to ongoing debates about freedom of expression, freedom of speech and freedom of the press. I name each of these concepts separately because, despite popular confusion, they are not the same thing (Patching and Hirst, 2014) . Freedom of expression is the right to individual self-expression through any means; it is an inalienable human right. Freedom of speech refers to the right (and the physical ability) to utter political speech, to say what others wish to repress and to demand a voice with which to express a range of social and political thoughts. Freedom of the press is a very particular version of freedom of expression that is intimately bound with the political economy of speech and of the printing press. Freedom of the press is impossible without the press and, despite its theoretical availability to all of us, this principle is impossible to articulate without the material means (usually money) to actually deploy a printing press (or the electronic means of broadcasting and publishing).Freedom of expression is immutable; freedom of speech subject to legal, ethical and ideological restriction (for better, or worse) and freedom of the press is peculiar to bourgeois society in that it entails the freedom to own and operate a press, not the right to say or publish on a level playing field. Access to freedom of the press is determined in the marketplace and is subject to the unequal power relationships that such determination implies.It is fitting to start with the Charlie Hebdo massacre because the loss of 17 lives makes this the most chilling of the three events and demands that it be given prominence in any analysis. No lives have been lost yet because Sony’s computers were hacked and the election of Syriza has not (yet) led to mass deaths in Greece.

An analysis of the environment as a means of assessing training needs in the Insurance industry in Australia

In the five years leading up to 2002 there were many significant changes in
the insurance industry in Australia that brought about a range of training
needs. These training needs arose from matters as diverse as mergers, increased competition, corporate failures, and legislative changes. This study includes findings from a survey of the insurance industry in Australia in the period 2000·2002 asa means of exploring the importance of the environment (marketplace) in predicting aspects of training needs. The findings demonstrate that an environmental analysis approach to training needs analysis can predict the type of training that organisations will subsequently need to provide, and thus has the potential to produce a more accurate assessment of training needs in the future. The findings also have application to more broadly based businesses operating in the financial services sector of the economy

Discrimination of origin of farmed trout by means of biometrical parameters, fillet chemical composition and flavour volatile compounds

To date it is well known that the quality of farmed trout is affected by diet composition, by feeding regime, by husbandry practices and by rearing conditions and environment. The trout processing industry and the large-scale retail trade, in consideration of the wide variability of trout quality and characteristics, have imposed, or will soon impose, quality criteria for the end product. Moreover, recent food scares and the malpractices of some food producers have increased public requests
for traceability. The aim of the present study was to evaluate the main chemical quality and the biometrical characteristics of rainbow trout produced in three different farms in Italy (two intensive farms, located one on mountain and one on plain, and an extensive farm in which fish fed only on naturally available nutrients) and to establish whether farmed trout
origins could be differentiated by these parameters. Trout farmed in the intensive mountain farm (IMF) showed the highest crude lipid content in the fillets and the fatty acids of their fillets were characterized by the highest percentage of MUFA. Trout farmed in the intensive plain farm (IPF) were characterized by low dressing percentage, and the lipid of their fillets
was rich in n-6 fatty acids. Trout stocked for the last year of their life in the extensive farm (EF) were leaner both in the carcass and in the fillets. The analysis of flavor volatile compounds showed some differences in the bouquet design, particularly differences in the amounts of n-3 and n-6 derivates volatile aldehydes and alcohols. All data significantly different
(P<0.05) were subjected to Linear Discriminant Analysis (LDA) and 8 variables were chosen to create two discriminant equations generating a strong prediction model for classification of farmed trout respective to their origins.

Analytical modeling of communication latency in multi-cluster systems

This paper addresses the problem of performance modeling of large-scale distributed systems with emphasis on communication networks in heterogeneous multi-cluster systems. The study of interconnection networks is important because the overall performance of a distributed system is often critically hinged on the effectiveness of this part. We present an analytical model to predict message latency in multi-cluster systems in the presence of processor heterogeneity. The model is validated through comprehensive simulation, which demonstrates that the proposed model exhibits a good degree of accuracy for various system sizes and under different operating conditions.

The role of communication in meeting MPA objectives

Marine Protected Areas (MPAs) play an important role in conserving the marine environment. An integral part of managing MPAs is communicating to its users and the broader community the existence of the park and its regulations. In two studies looking at the Victorian Marine National Parks and Sanctuaries it was found that there was a low level of awareness of the parks existence [1]. Television news was found in both studies to account for the majority of respondents awareness yet television advertisements were the main media used to inform the community, along with signage at parks and sanctuaries [2].

Education and communication are the main ways that management agencies inform the broader community about the parks and the regulations governing their management. They are generally directed at two main groups: formal education within schools and universities and communication towards the wider community. Communicating to the broader community the existence of an MPA is achieved through signs, brochures, self guided or ranger walks. These are developed by education experts within management agencies. Yet little is known of the public’s level of knowledge about MPAs or the marine environment. Therefore, our research aims to discover the communities existing knowledge of MPAs and the marine environment and how this can help create effective communication strategies. This research focuses on the public who use MPAs and the wider community in Victoria, Queensland and Western Australia.
