We propose that pretending is a cognitive faculty which enables us to create and immerse ourselves in possible worlds. These worlds range from the veridical to the fan- tastic and are frequently realised as stories varying from the fictional to the scientific. This same ability enables us to become immersed and engaged in such stories (which we may...

A qualitative inquiry of reviews of films featuring digital humanlike characters was performed by sampling user comments from three online reviewer aggregator sites: the Internet Movie Database, Rotten Tomatoes and Metacritic. The films chosen for analysis were: Final Fantasy: The Spirits Within (dir. Hironobu Sakaguchi and Motonori Sakakibara, 200...
Conference Paper
Full-text available
In a pilot study, participants were asked to watch sets of short movie excerpts featuring performances of a human actor, and 5 animated characters of varying human likeness and eeriness. After viewing, scales were used to estimate the believability of certain visual, motion and aural character traits and to gain an overall impression of how believa...

We present the results of an exploratory study investigating the feasibility of using multimedia software to teach life skills to adults with learning difficulties. As a precursor to determining whether the clients would benefit from the software, we needed to address the issue of realism in visual displays, to discover if photorealistic images of...

Keywords: Web Accessibility, WCAG Guidelines 1.0, automated testing, manual testing, partial accessibility. Abstract: In this paper we attempt to gauge the implementation of web accessibility guidelines in a range of Irish websites by undertaking a follow-up study in 2005 to one conducted by McMullin three years earlier (McMullin, 2002). Automatic...

The rubber hand illusion (RHI) is a body ownership illusion whereby congruently stroking a fake rubber hand and a subject's hidden hand while observing the rubber hand produces the illusion of them feeling the touch on the rubber hand and experiencing the rubber hand to be part of their own body. The parameters of the RHI have not been fully define...
Article
Thermostatically-controlled, electrical soil heating cables were used to examine the effects of subzero temperatures on winter barley growing in plots outdoors. Plants in plots without heating cables were exposed to naturally-occurring subzero temperatures (unheated), while those in corresponding plots with the cables (heated) were protected from s...
Article
The influence of sub-lethal and lethal doses of glyphosate (5 µg and 10 µg per plant) applied to the fourth leaf of barnyardgrass (Echinochloa crus-galli) was examined over a treatment period of up to 14 days. Assessments were undertaken on plant growth, chlorophyll fluorescence, absorption and translocation of [14C]glyphosate. Electronic autoradio...

Maize (Zea mays L. var. Bonnie) transformed with a gene encoding a 5-enolpyruvylshikimate 3-phosphate synthase with altered sensitivity showed over 100-fold greater resistance to the herbicide glyphosate (N-[phosphonomethyl]glycine) in comparison with its nontransformed progenitor (parental control) at the third-leaf stage. Studies with [C-14]-glyp...
Article
Full-text available
The absorption and efflux of [14C]-glyphosate (N-[phosphonomethyl]glycine) was studied in maize (Zea mays L. cv. Aussie) and soybean (Glycine max L. Merr. cv. Maple Arrow) cell suspensions. Glyphosate absorption was complex: at low external herbicide concentrations (3–250 (μM) there was evidence for a single active uptake system with an apparent Km...
Article
Full-text available
Previous work suggested that an increase in cell wall-loosening contributes to the maintenance of maize (Zea mays L.) primary root elongation at low water potentials ([psi]w). It was also shown that root elongation at low [psi]w requires increased levels of abscisic acid (ABA). In this study we investigated the effects of low [psi]w and ABA status...

Xyloglucan endotransglycosylase (XET) has been proposed to contribute to cell elongation through wall loosening. To explore this relationship further, we assayed this enzyme activity in suspensions of carrot (Daucus carota L.) cells exhibiting various rates of cell elongation. In one cell line, elongation was induced by dilution into dichlorophenox...
Article

A series of physical and chemical analyses were made on the expanding zone of maize seedling roots grown in hydroponics. Comparison of longitudinal profiles of local relative elemental growth rate and turgor pressure indicated that cell walls become looser in the apical 5 mm and then tighten 5–10 mm from the root tip. Immersion of roots in 200 mol...
Article
The effect of gibberellic acid (GA3) on phospholipid metabolism and α-amylase production was studied in aleurone tissue of two near-isogenic lines of wheat (Triticum aesuvum L.). Incubation of embryoectomized seeds from a GA-responsive line (rht3, tall) with GA3 caused the induction of α-amylase activity after a lag phase of 30 h. In the case of em...

When eight winter barley curtivars (Hordeum vulgare L.) were flooded at low temperature (6oc days, 2oc nights), a range of responses were found. Sensitivity to low temperature flooding was associated with gradual leaf wilting, whilst more tolerant -cultivars produced only leaf chlorosis after longer durations of flooding. When a 'sensitive' (Maris...
Article
Two winter wheat (Triticum aestivum L.) cultivars, Fredrick and Norstar, which differ in their winterhardiness potential, were compared with regard to the effects of nitrogen (N), phosphorus (P) and potassium (K) application, during acclimation, on the expression of four traits associated with winterhardiness — freezing, ice-encasement, and low tem...
Article
Ice encasement induced both quantitative and qualitative alterations in membrane proteins isolated from crown tissue of winter wheat (Triticum aestivum L.) cv. Norstar. Compared with a non-iced control, microsomes isolated after 1 day of icing showed the loss of at least 10 distinct polypeptides ranging from 14 to 80 kD, and the appearance of three...
Article
Full-text available
The physical properties and chemical composition of microsomal membranes were examined during a 7 day period of ice encasement in crown tissue of winter wheat (Triticum aestivum L. cv Norstar). Membrane damage, detected as an increase in microviscosity and electrolyte leakage, began between 1 and 3 days of icing, and was associated with a reduction...
Article
Full-text available
The functional and physical properties of cellular membranes isolated from Triticum aestivum, cvs Norstar and Fredrick, were altered coincident with changes in composition after a lethal ice-encasement stress and further during a 6 hour post-thaw period. Crowns encased in ice for a duration which inhibited regrowth, exhibited enhanced rates of elec...
