The Internet in Tertiary Education: A survey of students' Internet activity

This paper presents the findings from a survey of 752 Australian University students and their families. The aim was to determine the extent to which individuals engaged in various Communication, Recreation, Information, Production and Transaction activities on the Internet. The results clearly identify the popularity of certain Communication and Information-seeking activities and the limited way many Production technologies have been embraced at this stage. Amongst other things, the data highlights Internet activities where age discrepancies exist and thus, identifies activities that may become second nature for future generations of University students, such as email and information-seeking have become to current generations

Model-based clustering with data correction for removing artifacts in gene expression data

The NIH Library of Integrated Network-based Cellular Signatures (LINCS) contains gene expression data from over a million experiments, using Luminex Bead technology. Only 500 colors are used to measure the expression levels of the 1,000 landmark genes measured, and the data for the resulting pairs of genes are deconvolved. The raw data are sometimes inadequate for reliable deconvolution leading to artifacts in the final processed data. These include the expression levels of paired genes being flipped or given the same value, and clusters of values that are not at the true expression level. We propose a new method called model-based clustering with data correction (MCDC) that is able to identify and correct these three kinds of artifacts simultaneously. We show that MCDC improves the resulting gene expression data in terms of agreement with external baselines, as well as improving results from subsequent analysis.Comment: 28 page

A Posterior Probability Approach for Gene Regulatory Network Inference in Genetic Perturbation Data

Inferring gene regulatory networks is an important problem in systems biology. However, these networks can be hard to infer from experimental data because of the inherent variability in biological data as well as the large number of genes involved. We propose a fast, simple method for inferring regulatory relationships between genes from knockdown experiments in the NIH LINCS dataset by calculating posterior probabilities, incorporating prior information. We show that the method is able to find previously identified edges from TRANSFAC and JASPAR and discuss the merits and limitations of this approach

Toward an Understanding of Contemporary Korean American Piano Music: A Stylistic Analysis of In-transit (1999), Piano Sonata (2006), and Inter-Mez-Zo (2006) by Beata Moon

Beata Moon is a second-generation Korean American musician who is actively involved in the American music field. She is a performing pianist but also serves as a promoter of new music and aesthetic education. As a composer, Moon has developed a distinctive style that is eclectic and accessible to the audience. The focus of the study is a stylistic analysis of Beata Moon\u27s three major solo piano works: In-Transit (1999), Piano Sonata (2006), and Inter-Mez-Zo (2006). The analysis includes examination of form, harmony, melody, rhythm and keyboard usage in each of Beata Moon\u27s three major solo piano works. This study also provides Moon\u27s biographical information and a transcript of a one-on-one interview

Investigating Prospective Teachers as Learning Design Authors

This chapter reports on findings from a recent project situated in the area of preservice teacher education. The project investigated prospective teachers authoring and using their own contextualised learning designs. The chapter describes how 17 secondary and primary preservice teachers adapted existing, well-researched learning strategies to inform the design of their own specific online learning tasks and how they implemented these tasks in the context of their teaching practicum. The prospective teachers used an online learning design authoring system as a tool and flexible `test-bed for their learning designs and implementation. An account of the ways in which the prospective teachers developed sophisticated understandings of their chosen learning strategy and developed fresh insights into online and face-toface teaching issues is present

The adoption of e-trade innovations by Korean small and medium sized firms.

The purpose of this study was to explore the adoption of e-trade innovations by small-medium sized enterprises (SMEs) operating in South Korea. Employing a modified TAM model, which included the industry environment and convenience factors, we surveyed 164 SMEs to develop a useful refined model of innovation acceptance and continuity of use for international e-trade. We found that usefulness of the innovation was predictive of adoption, whilst convenience only predicted practical use but not continuing use. Moreover, industry variables were powerful predictors. Although e-trade offers SMEs considerable competitive advantage, it appears that widespread adoption is contingent upon a mature infrastructure

eBay: An authentic learning object

The Internet has evolved to its current form as a result ofuser-generated content and interactivity and this phenomenon must be more widely recognised informal education. This paperproposes that popular wehsites which are reflective ofhow society uses the Internet on a daily basis should provide the context for authentic and engaging online learning experiences. This position is established through the integration a/three socia-cultural views ojlearning: Situated Cognition, Distributed Cognition and Activity Theory. The integration ofthese three theories enables evaluation ofthe Internet as a mediating tool ofauthentic activity which is socially constructed and bound. The popular online auction site eBay is used to demonstrate the ideas raised throughout this paper

A Human Embryo of Carnegie Stage 13

A human embryo obtained from a salpinx resected for the treatment of an ectopic gestation was serially sectioned and observed. Four chambers of the heart were well delineated, though not completely separated. The dorsal pancreas was observed while the ventral pancreas was not yet formed. It was hard to clearly demarcate the cecal area because of no obvious dilatation. The septum transversum was nearly completely occupied by the hepatic parenchyme. The gall bladder-cyctic duct primordium was also observed. The intestine distal to the duodenum was attached to the posterior body wall by a prominent dorsal mesentery. The respiratory tree showed primary bronchi, and no mesenchymal differentiation around the tree was achieved yet. The mesonephric system showed variable developmental features depending on their location in the body. The mesonephric duct was already connected to the cloaca, and some localized dilatation of the duct surrounded by mesenchymal condensation, which would become the metanephric blastema, foretold the formation of the ureteric bud. The otocyst had been completely separated from the skin ectoderm and the endolymphatic duct had begun to form. Eye primordium observed was the optic cup. The well established lense placode impended to invaginate. Although this embryo showed a few characteristics of stage 14, it may be reasonable to regard this embryo as an older member of stage 13, considering the overall developmental status
