A review of some models for the analysis of contingency tables : a thesis presented in partial fulfilment of the requirements for the degree of Master of Arts in Statistics at Massey University

Some models proposed for the analysis of contingency tables are reviewed and illustrated with examples. These include standard loglinear models; models which are suitable for ordinal categorical variables such as ordinal loglinear, log­ multiplicative and logit models, and models based on an underlying distribution for the response; and models for incomplete and square tables. Estimation methods and inference are also discussed

A Pedagogy for Original Synners

Part of the Volume on Digital Young, Innovation, and the UnexpectedThis essay begins by speculating about the learning environment of the class of 2020. It takes place entirely in a virtual world, populated by simulated avatars, managed through the pedagogy of gaming. Based on this projected version of a future-now-in-formation, the authors consider the implications of the current paradigm shift that is happening at the edges of institutions of higher education. From the development of programs in multimedia literacy to the focus on the creation of hybrid learning spaces (that combine the use of virtual worlds, social networking applications, and classroom activities), the scene of learning as well as the subjects of education are changing. The figure of the Original Synner is a projection of the student-of-the-future whose foundational literacy is grounded in their ability to synthesize information from multiple information streams

Allatostatin-A neurons inhibit feeding behavior in adult Drosophila

How the brain translates changes in internal metabolic state or perceived food quality into alterations in feeding behavior remains poorly understood. Studies in Drosophila larvae have yielded information about neuropeptides and circuits that promote feeding, but a peptidergic neuron subset whose activation inhibits feeding in adult flies, without promoting metabolic changes that mimic the state of satiety, has not been identified. Using genetically based manipulations of neuronal activity, we show that activation of neurons (or neuroendocrine cells) expressing the neuropeptide allatostatin A (AstA) inhibits or limits several starvation-induced changes in feeding behavior in adult Drosophila, including increased food intake and enhanced behavioral responsiveness to sugar. Importantly, these effects on feeding behavior are observed in the absence of any measurable effects on metabolism or energy reserves, suggesting that AstA neuron activation is likely a consequence, not a cause, of metabolic changes that induce the state of satiety. These data suggest that activation of AstA-expressing neurons promotes food aversion and/or exerts an inhibitory influence on the motivation to feed and implicate these neurons and their associated circuitry in the mechanisms that translate the state of satiety into alterations in feeding behavior

Structural Racism and Youth Development

Youth of color have experienced poor outcomes relative to their white counterparts historically, and these disparities persist today. Researchers have offered a number of explanations for these disparities, some of the more popular of which have focused on individual deficiencies. If one elucidates the underlying theories of change of dominant practices and public policies in the youth field, it appears that, despite variation in approach and emphasis, they too have focused on individual behavior. While behavior is clearly an important contributor to the outcomes that individuals experience, it is not the sole determinant. Rather, we contend that there are larger, structural factors that contribute to the racial disparities between youth of color and their white counterparts that deserve systematic and sustained attention

Residential child care qualifications audit 2007

In recent years there has been a drive to develop a fully qualified residential child care sector in Scotland. In 2003 the Scottish Social Services Council (SSSC) announced the baseline qualifications for residential child care staff and set down a target for attaining it. This qualifications framework was subsequently reviewed and expanded in 2004. The Scottish Institute for Residential Child Care (SIRCC), commissioned by the Scottish Executive, has previously undertaken two inquiries into the qualification levels of the residential child care workforce in Scotland. The first Qualifications Audit (Frondigoun, Maclean, Hosie & Kendrick, 2002) was undertaken before the SSSC’s initial qualification framework was known and the second (Hunter, Hosie, Davidson & Kendrick, 2004) was based on it. The previous qualifications audit (Hunter et al., 2004) reported that 18% of residential child care staff were fully qualified in accordance with the SSSC’s qualification criteria (SSSC, 2004). The report forecast that the number of fully qualified staff would rise to 29.1% if all qualifications being undertaken were achieved. The purpose of this current audit is to determine whether levels of qualified staff have risen and to identify qualification trends throughout the residential child care sector in Scotland

National Autism Indicators Report: Vocational Rehabilitation 2016

Employment is about more than simply earning a paycheck - it influences quality of life, independence, and wellness. Historically, employment outcomes for adults with autism are poor. The U.S. Vocational Rehabilitation system (VR) is designed to provide support to states for implementation of services to assist people with disabilities to prepare for, find, and keep employment. VR data allow us to examine some outcomes for those with autism compared to their peers.To make a difference, research must reach those who need it. The National Autism Indicators Report series presents our research findings in a clearly communicated, open-access, online format to speed the delivery of information to decision-makers while maintaining very high standards of scientific credibility

Online citizen panels as an advance in research and consultation – A Review of pilot results

This paper details a new model for local government consultation and research. The model involves a local government partnering with a university to establish an online panel of citizens that is then used for consultations and research on a range of local government issues over time. The model was evaluated across an 18-month pilot involving three metropolitan councils in South Australia, each running its own panel. This paper details the rationale behind the panels, steps involved in their establishment, and what the most effective recruitment methods were to build panel membership. The model’s ability to recruit a wide audience of citizens as members, including those who would not normally participate in local government matters, is examined, as well as citizen expectations of the panel and satisfaction with being a member. Finally, key learnings from the pilot are identified. The pilot results demonstrate that such an online panel model can be used effectively in the local government context. The panels achieved citizen membership wider than that historically seen in local government consultation and research, and were sustainable in terms of continued participation and high levels of citizen satisfaction. Since the pilot, the project has grown to include seven councils and almost 2500 citizens. This is further evidence that this model offers a way forward for enhanced citizen participation in local government decision-making and policy development
