Event Processing through naming: Investigating event focus in two people with aphasia

Some people with aphasia may have trouble with verbs because of fundamental difficulties in processing situations in a way that maps readily onto language. This paper describes a novel assessment, the Order of Naming Test, that explores the conceptual processing of events through the order in which people name the entities involved. The performance of non-brain damaged control participants is described. The responses of two people with non-fluent aphasia are then discussed. Both 'Helen' and 'Ron' showed significant difficulty with verbs and sentences. Ron also had trouble on a range of tasks tapping aspects of event processing, despite intact non-verbal cognition. While Helen's performance on the Order of Naming Test was very similar to the controls, Ron's differed in a number of respects, suggesting that he was less focused on the main participant entities. However, certain aspects of his response pointed at covert event processing abilities that might be fruitfully exploited in therapy

Negative Linear Compressibility

While all materials reduce their intrinsic volume under hydrostatic (uniform) compression, a select few actually \emph{expand} along one or more directions during this process of densification. As rare as it is counterintuitive, such "negative compressibility" behaviour has application in the design of pressure sensors, artificial muscles and actuators. The recent discovery of surprisingly strong and persistent negative compressibility effects in a variety of new families of materials has ignited the field. Here we review the phenomenology of negative compressibility in this context of materials diversity, placing particular emphasis on the common structural motifs that recur amongst known examples. Our goal is to present a mechanistic understanding of negative compressibility that will help inform a clear strategy for future materials design.Comment: Submitted to PCC

MORPHOLOGY, REPRODUCTION, SEASONAL ACTIVITY AND HABITAT USE OF A NORTHERN POPULATION OF THE SMOOTH GREENSNAKE (OPHEODRYS VERNALIS)

The Smooth Greensnake (Opheodrys vernalis) is a small, slender, oviparous, colubrid snake that is widely distributed in North America. Nonetheless, there have been few studies on this species, and little is known about Canadian populations. The objective of this study was to examine morphology, reproduction, seasonal activity and habitat use of a northern population of the Smooth Greensnake. Individuals were captured during the summers of 2007-2010 in southwestern Manitoba, Canada. Females were larger and relatively heavier than males, but clutch size did not consistently increase with body size. In addition, 59% (on average) of available adult females were gravid in any given year, suggesting that females may not reproduce each year. Males had relatively longer heads and longer tails than females. Males were more common in early August; otherwise, females were more common. The peak of male activity in August suggests that fall mating might occur in this species, but this was not confirmed. Finally, Smooth Greensnakes were most commonly found in grassland, and there were no differences in habitat use between the sexes. Further research on northern populations of Smooth Greensnakes would provide valuable information on this little-studied species

Land use, associated eel production, and abundance of fish and crayfish in streams in Waikato, New Zealand

The density and biomass of fish and crayfish, and the production of eels, was compared among streams in native forest, exotic forest, and pasture. Populations were estimated by multiple-pass electroshocking at 11 sites in hill-country streams in the Waikato region, North Island. Three sites were in native forest, four in exotic forest, and four in pasture. Length of stream sampled at each site was 46-94 m (41-246 m2 in area), and catchment areas up stream of the sites ranged from 0.44 to 2.01 km2. A total of 487 fish were caught. The species were longfinned and shortfinned eels, banded kokopu, Cran's and redfinned bullies, and common smelt. Eels were the most abundant fish in all three land-use types, and shortfinned eels were more abundant at pastoral sites (mean density 1.11 fish m-2) than longfinned eels (mean density 0.129 fish m-2). Banded kokopu were present only at forested sites. Mean fish densities were greater at pastoral sites (1.55 fish m-2) than under either native forest (0.130 fish m-2) or exotic forest (0.229 fish m-2). Mean fish biomass was also greater at pastoral sites (89.7 g m-2) than under native forest (12.8 g m-2) or exotic forest (19.3 g m-2). Longfinned eels made a greater contribution to the fish biomass at all sites than did shortfinned eels. Densities of crayfish were high (0.46-5.40 crayfish m-2), but were not significantly different between land-use types. Crayfish biomass ranged from 1.79 to 11.2 g m-2. Total eel production was greater at pastoral sites (mean 17.9 g m-2 year-1) than at forest sites (mean 2.39 g m-2 year-1)

Development of a hybrid multi-scale simulation approach for spray processes

This paper presents a multi-scale approach coupling a Eulerian interface-tracking method and a Lagrangian particle-tracking method to simulate liquid atomisation processes. This method aims to represent the complete spray atomisation process including the primary break-up process and the secondary break-up process, paving the way for high-fidelity simulations of spray atomisation in the dense spray zone and spray combustion in the dilute spray zone. The Eulerian method is based on the coupled level-set and volume-of-fluid method for interface tracking, which can accurately simulate the primary break-up process. For the coupling approach, the Eulerian method describes only large droplet and ligament structures, while small-scale droplet structures are removed from the resolved Eulerian description and transformed into Lagrangian point-source spherical droplets. The Lagrangian method is thus used to track smaller droplets. In this study, two-dimensional simulations of liquid jet atomisation are performed. We analysed Lagrangian droplet formation and motion using the multi-scale approach. The results indicate that the coupling method successfully achieves multi-scale simulations and accurately models droplet motion after the Eulerian–Lagrangian transition. Finally, the reverse Lagrangian–Eulerian transition is also considered to cope with interactions between Eulerian droplets and Lagrangian droplets.This work was supported by the Engineering and Physical Sciences Research Council of the UK (grant number EP/L000199/1)

Interpersonal Solidarity in Relationships: A Cultural Analysis of Lawyers vs. Sports Agents

The cultural affects on relationship solidarity and satisfaction in relationships between lawyers and their clients, and sports agents and their professional athlete clients was examined. The results were gathered through a process of correlation tests and frequency report tables. All four groups of subjects were asked to complete a twenty questions survey which contained variables such as interpersonal solidarity, relational satisfaction, and communicative patterns of interaction. The results indicated that the two types of relationships are adversely co-dependent with respect to self-disclosure and it\u27s relationship to interpersonal solidarity within a client-agent relationship

“Who Now Shall Believe That Liar, Merlin?”: The Prophecies of Merlin in History

This research article examines Merlin\u27s prophecies and how their political use has shifted from one of belief and of direct political significance, to general disbelief. It examines how the use of prophecy exploited the prestige of King Arthur and Merlin. Tactics used to take advantage of this prestige ranged from rulers claiming blood relation to King Arthur to learned men interpreting existing prophecies. Sources, such as Wace, Geoffrey of Monmouth, and modern day novelists, are used to illustrate the prophecies’ evolution from the twelfth to the twentieth century and what it means

Bond behavior of fiber reinforced polymer bars under direct pullout conditions

This paper examines the behavior of Eurocrete fiber-reinforced polymer (FRP) bars (glass, carbon, aramid, and hybrid) in concrete under direct pullout conditions. More than 130 cube specimens were tested in direct pullout where no splitting was allowed to develop. In normal concrete, the mode of bond failure of FRP bars was found to differ substantially from that of deformed steel bars because of damage to the resin rich surface of the bar when pullout takes place. Bond strengths developed by carbon fiber-reinforced polymer and glass fiber-reinforced polymer bars appear to be very similar and just below what is expected from deformed steel bars under similar experimental conditions. The load slip curves highlight some of the fundamental differences between steel and FRP materials. This paper reports in detail on the influence of various parameters that affect bond strength and development such as the embedment length, type, shape, surface characteristics, and diameter of the bar as well as concrete strength. The testing arrangement is also shown to influence bond strength because of the “wedging effect” of the bars
