The design of web sites with quality user interface

Usability engineering focuses on how well Web sites are structured. Many designers are unaware of the diversity of usability engineering and what it can offer the developer in efforts to produce a usable Web site. Three researchers in the field, Borges, Morales, and Rodriquez (1998), have created a style guide of content, which recommends essentials for user-friendly Web sites. They included in their list Common Look and Feel (CL&F), Information Display, Navigation, and Labels. This research paper goes through the steps it took to create a quality Web site using the style guides of the noted researchers

The Conservatives and the Union: The 'New English Toryism' and the Origins of Anglo-Britishness

The Union has for over a century been one of the cornerstones of Conservative politics, but with the changes to the old union state in the last 20 years, its value has been increasingly questioned. While the Conservative Party remains committed to maintaining the Union, a new English Toryism is emerging, which has a strong continuity with an older English Toryism which was partially buried by the ascendancy of Unionism. English Tories have always considered the Union to be desirable, but it comes second in their thinking to the need to protect the sovereignty of the British state, the core of which is England and its traditional institutions. What is new about the contemporary Conservative Party is that there is within it the revival of an English Toryism which is happy to discard the older clothes of Empire and Union once so important to Conservative identity and which is unabashedly English in its focus. For an increasing number of contemporary Conservatives, there no longer seems to be any passion about defending the Union or even of continuing to think about the United Kingdom in Unionist terms

Near-Infrared Spectroscopy Used to Predict Soybean Seed Germination and Vigour

Rapid, non-destructive methods for measuring seed germination and vigour are valuable. Standard germination and seed vigour were determined using 81 soybean seed lots. From these data, seed lots were separated into high and low germinating seed lots as well as high, medium and low vigour seed lots. Near-infrared spectra (950–1650 nm) were collected for training and validation samples for each seed category and used to create partial least squares (PLS) prediction models. For both germination and vigour, qualitative models provided better discrimination of high and low performing seed lots compared with quantitative models. The qualitative germination prediction models correctly identified low and high germination seed lots with an accuracy between 85.7 and 89.7%. For seed vigour, qualitative predictions for the 3-category (low, medium and high vigour) models could not adequately separate high and medium vigour seeds. However, the 2-category (low, medium plus high vigour) prediction models could correctly identify low vigour seed lots between 80 and 100% and the medium plus high vigour seed lots between 96.3 and 96.6%. To our knowledge, the current study is the first to provide near-infrared spectroscopy (NIRS)-based predictive models using agronomically meaningful cut-offs for standard germination and vigour on a commercial scale using over 80 seed lots

Fishing the georges river: Cultural diversity and urban environments

The Georges River runs through the heart of Sydney’s most culturally diverse population, including long-established Aboriginal and Anglo-Celtic communities as well as the many more recent immigrant communities that have developed since the 1980s. Most people in all these communities are in working-class employment (if they have jobs at all), are living in densely packed suburbs and, despite some gentrification on the margins, still have significant disadvantages in educational and social infrastructure. As well as being a large river with scenic parklands threading along its lower estuarine reaches, the Georges River is also the focus of intensifying ethnic conflicts which often spill over into the media. The names of the river’s suburbs – Cabramatta, Liverpool, Bankstown, Macquarie Fields and Lakemba – are well known around Australia for their tensions. Yet, recent surveys of Australian attitudes to cultural diversity have demonstrated a widespread endorsement of the desire to reach across cultural differences despite the effect of international events and the media in increasing the hostile polarisation between ethnic groups (Ang et al. 2002, 2006). This paper will ask whether considering the area’s complex relationships and tensions through the lens of ‘everyday’ activities might allow us to understand those conflicts more clearly

Quantification of the Dental Morphology of Orangutans

Orangutans are believed to have close biological affinities to humans. Teeth being the hardest tissue provide useful information on primate evolution. Furthermore, knowledge of the pulp chamber and root canal morphology is important for dental treatment. A female Bornean orangutan and a Sumatran male orangutan skull were available for this study. Both of their dentitions, comprising 50 teeth, were scanned employing the cone-beam computed tomography for both metrical and nonmetrical analyses. Measurements included tooth and crown length, root length, enamel covered crown height, root canal length (posterior teeth), length of pulpal space (anterior teeth), and root canal width. Nonmetrical parameters included number of canals per root, number of foramina in each root, and root canal morphology according to Vertucci’s classification. It was found that the enamel covered crown height was the longest in the upper central incisors although the canine was the longest amongst the anterior teeth. Both the upper premolars were three-rooted while the lower second premolar of the Sumatran orangutan was two-rooted, with two foramina. The mandibular lateral incisors of the Bornean orangutan were longer than the central incisors, a feature similar to humans. In addition, secondary dentine deposition was noticed, a feature consistent with aged humans

Genetic Influences on Behavioral Outcomes After Childhood TBI: A Novel Systems Biology-Informed Approach

Objectives: To test whether genetic associations with behavioral outcomes after early childhood traumatic brain injury (TBI) are enriched for biologic pathways underpinning neurocognitive and behavioral networks.Design: Cross-sectional evaluation of the association of genetic factors with early (~ 6 months) and long-term (~ 7 years) post-TBI behavioral outcomes. We combined systems biology and genetic association testing methodologies to identify biologic pathways associated with neurocognitive and behavior outcomes after TBI. We then evaluated whether genes/single nucleotide polymorphism (SNPs) associated with these biologic pathways were more likely to demonstrate a relationship (i.e., enrichment) with short and long-term behavioral outcomes after early childhood TBI compared to genes/SNPs not associated with these biologic pathways.Setting: Outpatient research setting.Participants:140 children, ages 3–6:11 years at time of injury, admitted for a TBI or orthopedic injury (OI).Interventions: Not Applicable.Main Outcome Measures: Child behavior checklist total problems T score.Results: Systems biology methodology identified neuronal systems and neurotransmitter signaling (Glutamate receptor, dopamine, serotonin, and calcium signaling), inflammatory response, cell death, immune systems, and brain development as important biologic pathways to neurocognitive and behavioral outcomes after TBI. At 6 months post injury, the group (TBI versus OI) by polymorphism interaction was significant when the aggregate signal from the highest ranked 40% of case gene associations was compared to the control set of genes. At ~ 7 years post injury, the selected polymorphisms had a significant main effect after controlling for injury type when the aggregate signal from the highest ranked 10% of the case genes were compared to the control set of genesConclusions: Findings demonstrate the promise of applying a genomics approach, informed by systems biology, to understanding behavioral recovery after pediatric TBI. A mixture of biologic pathways and processes are associated with behavioral recovery, specifically genes associated with cell death, inflammatory response, neurotransmitter signaling, and brain development. These results provide insights into the complex biology of TBI recovery

Evaluating major curriculum change:the effect on student confidence

Aim: The aim of this study was to evaluate the effect of major curriculum change within a UK dental school on final-year student self-rated confidence levels. Methods: Final-year dental students graduating in each year between 2007 and 2012 completed the same course evaluation questionnaire, which assessed their confidence in relation to a range of clinical procedures using a Likert-type scale. This period spanned the introduction of a new curriculum and allowed analysis of differences in self-rated confidence between students graduating from the old (2007 and 2008) and new (2009–2012) curricula, across thirty key procedures. Results: New curriculum students showed significantly higher self-confidence ratings in nineteen of the thirty procedures, compared with those on the old curriculum. For the remaining eleven procedures there was no significant difference between the two curricula. The proportion of students on the outcomes-based curriculum rating themselves as 'confident” was statistically significantly higher in seven out of the thirty procedures, when compared with the traditional curriculum, and unchanged or nonsignificantly increased in the remainder. Discussion and conclusions: The relationship between specific curricular innovations and student confidence is considered, as is the usefulness of self-rated confidence in curriculum evaluation. Curriculum change appeared to have a positive effect on student confidence across a range of procedures
