The behaviour of the Sterling/European Currency Unit (ECU) exchange rate is examined both during the time before Britain joined the European exchange rate mechanism (ERM) and during the time of Britain's membership. During the latter period, a GARCH (1, 1) model fits the data well but during the pre-ERM period there is evidence of significant non-linear - possibly chaotic - structure in the GARCH residuals. Analysis of the dominant Lyapunov exponents and correlation dimension for the pre-ERM period suggests that the data generation process may be chaotic and this is reinforced by the highly significant BDS statistics obtained for this sample period. © 1997, Taylor & Francis Group, LLC.

A characteristic of scapulothoracic dysfunction is the tendency for the upper regions of the trapezius to hypertrophy in relation to its middle and lower portions. This creates a muscular imbalance that can alter scapular position and subsequently the length-tension relationship of the shoulder muscles. Tape was applied over the right upper trapezius to inhibit electrical activity in the muscles of 10 uninjured subjects. EMG activity was recorded in two locations of the upper trapezius and one location in the middle to lower trapezius region while each subject maintained an isometric contraction designed to activate both muscles. With the tape applied, there was a statistically significant reduction in EMG activity of the upper trapezius with a corresponding increase in the middle/lower trapezius. The ability of the tape to alter trapezius activity in this fashion may help correct muscular imbalances in the trapezius muscle.

Several major transitions in language use take place during the first 5 years of life. Each transition allows the child to move to a higher level of complexity of expression and to accomplish communicative goals more flexibly and precisely than was done at the previous level. At least three of these transitions appear to be modulated to some degree by speech. In the first transition, prellnguistic to early linguistic communication, babbling provides the infant with a prelinguistic form of vocal behavior that is in many ways analogous to language. A second transition takes place in the movement from single words to multiword combinations. In the process of this transition, word order becomes a means by which children convey semantic role information, and transitional forms such as successive one-word utterances help to facilitate the child's leap from single-word speech to multiword sentences. A third transition involves the development of phonological awareness, an important basis for the acquisition of literacy, which builds on the foundation laid by the phonological system for articulation. In each of these transitions, speech appears important for mediating the move to a higher language level. This paper considers the question of how these transitions can be facilitated in children who use augmentative and alternative communication rather than speech as a first expressive system, in order to provide as precise and flexible a communication modality as possible to children with severe speech impairments.

The relative abundance and size distributions of juvenile winter flounder, Pseudopleuronectes americanus, were compared in two areas; an anthropogenically altered marina basin and a natural intertidal flat habitat. Winter flounder were sampled from March through November 1990-95 with a 1.0 m beam trawl. No significant difference was observed in catch-per-unit-effort between areas but significant differences were found between seasons. Relative abundance (number of flounder/m2) increased from spring (0.007 marina and 0.011 intertidal flats) to summer (0.059 marina and 0.051 intertidal flats) and then declined slightly in the autumn (0.047 marina and 0.027 intertidal flats). Relative abundance was similar between areas from 1990-95 but differed between years. Length frequency distributions of winter flounder were similar between areas for all seasons but mean sizes were statistically different in summer. These results suggest that juvenile winter flounder are equally abundant in both natural intertidal habitats and marina basins, indicating that both could serve as nursery areas. However, more specific research is required to resolve the relative importance of marinas and the factors involved in utilization of each habitat.

Three new Jaltomata species from the department of Ancash, Peru, are described and illustrated. The three species are distinguished from others in the genus by features of the flowers, hairs, and leaves. Fruits of Jaltomata cajacayensis S. Leiva and Mione are gathered for consumption. Jaltomata lomana Mione and S. Leiva is known only from a single fog-dependent plant community, a lomas formation. Jaltomata yungayensis Mione and S. Leiva is widely distributed at high elevations.

Little is known about the life history of mayflies that inhabit temporary ponds. The purpose of this study was to observe and quantify life histories attributes of Siphlonurus typicus, which is known to reside in temporary ponds. Weekly samples of nymphs were taken from two temporary ponds in eastern Connecticut from March to June, 1999. Individuals were graded into 11 maturity classes, based on developmental characteristics, as a means of predicting population maturity rates. Head capsule widths (HCWs) were used to determine if growth occurred between maturity classes. Degree days were found to be an excellent predictor for population maturity (r2 = 0.963, p < 0.0001). Nymphs that hatched earlier in the year had larger HCWs than nymphs that hatched later in the year, possibly because of different temperature regimes. The University of Connecticut Forest pond (UCF) population matured faster than the Merrow Meadows pond (MER) population, but both sexes of the UCF population tended to be smaller than their counter parts from the MER population. Sex ratios were female bias for the UCF population (1.35:1), but were not different for the MER population. Adult emergence and mating occurred from 27 May to 21 June. There was a positive relationship between number of eggs per female and female body length. Oviposition at both sites occurred directly on the ponds, pond inlets, and outlets, indicating that pond populations were the result of local migrants as well as permanent residents. Temperature was a determining factor of maturity and fecundity for Siphlonurus typicus.

We prove two art gallery theorems in which the guards must guard one another in addition to the gallery. A set G of points (the guards) in a simple closed polygon (the art gallery) is a guarded guard set provided (i) every point in the polygon is visible to some point in G; and (ii) every point in G is visible to some other point in G. We prove that a polygon with n sides always has a guarded guard set of cardinality ⌊(3n-1)/7⌋ and that this bound is sharp (n5); our result corrects an erroneous formula in the literature. We also use a coloring argument to give an entirely new proof that the corresponding sharp function for orthogonal polygons is ⌊n/3⌋ for n≤6; this result was originally established by induction by Hernández-Peñalver. © 2003 Elsevier B.V.

Caring is a concept that has been studied in numerous helping professions but has yet to be researched from a counseling perspective. In this qualitative research study, 13 master’s-level counseling interns were interviewed to better understand their perceptions of caring in the counseling relationship. Results suggest that these interns perceive that supporting desired outcomes, a personal capacity for caring, maintaining therapeutic conditions, mutuality in the counseling relationship, and a dynamic flow of communication are important attributes of the counseling relationship when caring is present The findings suggest further research that explores the concept of caring in the counseling relationship may be warranted. © 2002 American Counseling Association.

Determining the relative efficacy of various intervention programs for auditory processing disorders (APD) is a major goal in the field of rehabilitative audiology. Currently, because of their widespread availability, the most commonly used measuring tools to assess the central auditory system have been behaviorally based. Such measures do have notable disadvantages in that they may be influenced by a number of extraneous variables that may impede, or at least influence, efficacy measures. Electrophysiologic measures offer unique advantages not available from the behavioral measures. A significant amount of research has been completed offering compelling evidence relative to the clinical utility of a number of these electrophysiologic measures, including the maximum length sequences-auditory brainstem response, the middle latency response, the obligatory long latency responses, and the MMN and P3 event-related potentials. This article will review the current research related to electrophyiologic measures and present a rationale for including them in the management program.

The present paper examines how followers of 'Abd al-Rahcombining dot belowmān b. 'Amr al-Awzā'ī and Sufyān al-Thawrī tried to create boundaries between the nascent madhhabs that claimed them as eponyms. In the absence of significant differences in legal method, students turned to the two shaykhs' responses to the 'Abbāsid revolution to draw distinctions between them. The Arabic biographical sources contain stories of their responses to the revolution that reveal a dialogue between followers of the two shaykhs about the relative merits of their choices. The changing interpretations of their attitudes toward the 'Abbāsid regime and the exaggeration evident in the anecdotes examined have significant implications for our reading of medieval Arabic biographical sources.

Amid all enthusiasm regarding the rise of the Digital Age, industrial espionage remains the dark side of the post-industrial revolution. The Federal Industrial Espionage Act of 1996 aimed at leveling the field regarding widespread cheating and stealing of intellectual properties by competitors in the marketplace. In this paper we aim at defining various forms of industrial espionage in the light of the ongoing information technology revolution. © Emerald Backfiles 2007.

The decision about whether to co-brand is based on two conditions: the opportunities for creating a competitive advantage, and the operational benefits that will result. When these conditions are favorable, a firm must pick the right co-branding partner, using such criteria as (a) compatibility between brands, (b) market volatility, (c) investment requirements and arrangements, and (d) the prospective partner's commitment to the agreement. The firm and its chosen partner then enter the phase of courtship and potential conflict, which involves planning, negotiation, and conflict avoidance and management. Finally, they must create an exit strategy, in case the co-branding arrangement fails to live up to its promise.

Background: There is an increasing recognition that the communication problems one observes in persons with aphasia extend beyond verbal deficits and that the myriad of symptoms observed are not solely due to a faulty linguistic system. Rather, there exists a coalition of causal elements resulting in a wide range of communicative deficits. There is some preliminary evidence suggesting that communicative success of clients with aphasia may depend on the integrity of executive function skills. Executive functions are called into play when an individual is involved in a complex, novel activity. They allow us to plan, sequence, organise, and monitor goal-directed activities in a flexible manner as demanded by situational and environmental changes. When linguistic skills are impaired, individuals need to rely on other cognitive skills in order to communicate. Aims: The purpose of this study was to explore executive functioning ability in persons with aphasia. Methods & procedures: A total of 15 individuals with aphasia and 12 healthy control subjects participated in this study. Three dimensions of performance were examined (accuracy, speed, and efficiency) in the context of neuropsychological tests designed to examine cognitive flexibility and goal-directed planning (Wisconsin Card Sorting Test, Porteus Maze Test, Tower of London, and Tower of Hanoi). Outcomes & results: Results indicated that the two groups performed with similar levels of accuracy on two of the four tests. However, significant differences were found on all speed and efficiency variables, suggesting decreased executive functioning skills in the group of individuals with aphasia. Conclusions: It is important to consider executive functioning ability in clients with aphasia and attempt to determine the influence of executive function skill on communicative performance. Understanding the cognitive abilities as well as the linguistic abilities of these clients may ultimately help clinicians determine which patients are better candidates for intervention as well as which treatment approaches would be most efficient and beneficial.

This study examined script knowledge in 20 subjects who sustained a stroke (10 with left hemisphere brain damage and aphasia and 10 with right hemisphere brain damage) and 10 neurologically normal subjects. Script knowledge was examined via performance on three tasks: procedural sequencing, procedure production, and procedural discourse. Neurologically normal subjects performed all tasks accurately, and all subjects in the stroke group completed at least one of the three tasks for each script accurately, suggesting that script knowledge was preserved in this mildly brain-damaged population. However, significant differences were obtained between the neurologically normal and stroke groups when overall performance was examined. These findings suggest that additional cognitive processes influence task performance. Implications of these findings are discussed.
