Least-biased correction of extended dynamical systems using observational data

We consider dynamical systems evolving near an equilibrium statistical state where the interest is in modelling long term behavior that is consistent with thermodynamic constraints. We adjust the distribution using an entropy-optimizing formulation that can be computed on-the- fly, making possible partial corrections using incomplete information, for example measured data or data computed from a different model (or the same model at a different scale). We employ a thermostatting technique to sample the target distribution with the aim of capturing relavant statistical features while introducing mild dynamical perturbation (thermostats). The method is tested for a point vortex fluid model on the sphere, and we demonstrate both convergence of equilibrium quantities and the ability of the formulation to balance stationary and transient- regime errors.Comment: 27 page

Statistical Modelling of Pre-Impact Velocities in Car Crashes

The law wants to determine if any party involved in a car crash is guilty. The Dutch court invokes the expertise of the Netherlands Forensic Institute (NFI) to answer this question. We discuss the present method of the NFI to deter- mine probabilities on pre-impact car velocities, given the evidence from the crash scene. A disadvantage of this method is that it requires a prior distribution on the velocities of the cars involved in the crash. We suggest a different approach, that of statistical significance testing, which can be carried out without a prior. We explain this method, and apply it to a toy model. Finally, a sensitivity analysis is performed on a simple two-car collision model

Myall Lakes National Park, the Boolambayte Sand Ridge: its Extent, Vegetation, Geomorphology and Marks of European Settlement

The Boolambayte sand ridge (Bsr), recognized by Myerscough and Carolin (2014), is part of the Pleistocene sand barrier system mapped by Thom et al. (1992) and Hashimoto and Troedson (2008) in the valley of the Upper Myall River to the shores of Bombah Broadwater. Bsr comprises areas of sand on the south-western shore of Two-Mile Lake (the western arm of Boolambayte Lake). Features of Bsr reported in Myerscough and Carolin (2014) were based largely on interpretation of aerial photos; this study is based on observations on the ground. As a result, Bsr is defined more precisely. Freely draining sands were found to be in discontinuous patches along the lake shore. All patches were deposited before their eastern edges became the current lake shore, except one, which appeared to have formed as a lake sand bar. Evidence indicates that, until probably the last 2 - 3 m of the Holocene rise in sea level, waters of Two-Mile Lake joined Bombah Broadwater at the end of the lake bar running west from Bombah Point. Investigation of the vegetation of freely draining sites along Bsr shows that, though they carry Dry Sclerophyll Forest (DSF) of Myerscough and Carolin (1986 & 2014), the understoreys of most of them contain more wet heath plant spp. than do sites with DSF on sands in central parts of the Upper Myall River Valley, as described in Myerscough and Carolin (2014). Also described are various effects of European settlement to which the area has been subjected, particularly in its southern third

Application Usage and Usefulness Assessment for Web-Based Intranet Systems (W-BIS) Applications

Previous research concerning Web-Based Intranet Systems (W-BIS) defined nine categories of activities or tasks for which the W-BIS systems were utilized (Myerscough, Richards, and Becker 1997)

The Relationship of Age and Gender on User Information Satisfaction for Web-Based Intranet Systems (W-BIS) Applications

A recent survey of business executives showed that of 169 decision makers who responded to a survey by the Business Research Group, over fifty percent have either already implemented an internal web site or are in the process of developing such a site (Engler, 1996). These results were similar to those reported in Information Week, which showed that 49% of those firms responding to the survey already had direct Internet access for their employees. According to this same survey, this figure is expected to increase to 67% of these same firms by the spring of 1997 with another 10% of the firms testing the viability of such a connectivity policy (Yankelovich, 1996)

The effect of a postmodern career life story intervention on disadvantaged grade 12 learners.

This research sought to explore the effects of a postmodern career life story intervention on a sample of eight disadvantaged grade 12 learners. A qualitative research design using pre and post intervention interviews was used to explore whether the participants reevaluated or reinterpreted their responses to the interview questions in light of the intervention. The results of the study indicated that the participants experienced increased self-understanding, self-esteem, initiative and hope, optimism and empowerment through the intervention. The participants appreciated the time and space to be able to reflect on their lives. It appears as if all the various components of the life story intervention had a powerful impact on the participants. Writing life stories and using art materials appeared to be a method that was effective with disadvantaged grade 12 learners

Translingual Pedagogy in the First-Year Composition Classroom: an Examination of Divergent Student Uptake

117 PagesWhat impact can translingual pedagogy have in introductory composition classes? This thesis describes how first-year composition (FYC) students at a Primarily White Institution (PWI) participated in complicated, divergent uptake as they learned about terms such as translingualism, translation, and Global Englishes in the Fall of 2022. The research for this project was guided by the following questions. 1. In what ways were students understanding, resisting, or engaging with ideas such as Global Englishes, translingualism, and translation? When did moments of “discursive turbulence” occur in student uptake, and what was the result of that turbulence? (Ware and Zilles) 2. How did students understand translation and all communication as fluid, culturally and rhetorically situated, and beyond alphanumeric text, including semiotic and multimodal resources? How did students understand the concept of translingualism, and themselves as translingual communicators in the world? 3. How were students of different linguistic backgrounds developing linguistic empathy for the speakers of marginalized languages that do not fit into the monolingual “norm” in the U.S. academic system? 4. How can FYC instructors make translingual pedagogy accessible and comprehensible for traditionally considered “monolingual” English-speaking students? What impact does translingual pedagogy have on our “multilingual” students? Chapter 1 of this thesis reviews literature that discusses the importance of translingual pedagogy in language arts classrooms. Then, this chapter talks about translation research and especially focuses on Laura Gonzales’ concept of “A Revised Rhetoric of Translation” in her book, Sites of Translation. Chapter 2 considers the historical relationship between the linguistics, TESOL, and composition fields. Then, the chapter dives into the research questions that guided this project and the different methodologies used to conduct this project. More specifically, I describe a narrative theory and activity theory approach that I adopted as I collected student data. The chapter also gives an overview of the class I taught, and the components students had to complete in each unit. Chapter 3 gives an overview of my process as I collected data from student writing. In this chapter, I give my overall impressions of how students learned important class terms, such as translingualism, translation, and Global Englishes. Then, I chose 5 specific students to research whose uptakes were diverging and unique as they processed class terms in their writing. For each of the five students, I create a P-CHAT map and a collage to visually represent the students’ writing. I provide an analysis of each image and a description of the insights I gained about student uptake as I created and processed these visual representations of the data. Chapter four offers my interpretation of the data I collected. This chapter explores Ware and Zilles’s concept of “discursive turbulence” and how turbulence frames the stops and starts students experience in their learning. Then, I draw conclusions from the data and offer pedagogical recommendations for instructors seeking to incorporate translingual pedagogy in their FYC classroom. I also discuss the limitations of the project and suggestions for future research regarding divergent uptake and discursive turbulence.
