Editorial. Clinical pragmatics: an emergentist perspective

[First Paragraph] Clinical pragmatics has been a major growth area in clinical linguistics and speech and language pathology over the past two decades. Its scope is vast: if we define pragmatics in broad terms, there are no communicative disorders which do not involve pragmatic impairment at least to some degree (Perkins, 2003). Early work in the area tended to focus on the application of pragmatic theory in the analysis of pragmatic impairment (e.g. speech act theory (Hirst, LeDoux, & Stein, 1984), conversational implicature (Damico, 1985) and, more recently, relevance theory (Leinonen & Kerbel, 1999)) and on the development of pragmatic assessments, tests and profiles which included a theoretically eclectic range of items drawn from both pragmatic theory and elsewhere (e.g. Bishop, 1998; Penn, 1985; Prutting & Kirchner, 1983). In more recent years there has been an increasing interest in the neurological and cognitive bases of pragmatic impairment (e.g. Paradis, 1998; Perkins, 2000; Stemmer, 1999) and in the use of interactional approaches such as conversation analysis (e.g. Goodwin, 2003). This special issue of Clinical Linguistics and Phonetics draws on all of these areas but focuses on a particular aspect of pragmatic impairment which has often been overlooked – namely, that the behaviours we describe as pragmatic impairments are in fact the outcome of very varied and highly complex processes. This neglect is partly due to a common tendency to see pragmatics as a separate ‘level’ or even ‘module’ of language, on a par with syntax and semantics. Influenced on the one hand by speech act theory, with its distinction between language structure and communicative acts, and on the other hand by clinical populations who were either able to communicate well despite being linguistically impaired or else were poor communicators despite having good linguistic ability, clinicians assumed there to be a clear dissociation between linguistic and pragmatic competence. Although there is still considerable neurological evidence for a broadly modular view in terms of the lateralisation of linguistic and pragmatic functions, there is also compelling evidence for seeing pragmatic impairment as a more complex, non-unitary phenomenon. Non-modular, or ‘interactional’, views of pragmatic impairment have been influenced by connectionist and functional models of linguistic and cognitive processing (e.g. Bates, Thal, & MacWhinney, 1991), by a growing awareness of the role played in pragmatics by cognitive capacities such as inference, theory of mind and executive function (Martin & McDonald, 2003), and by approaches such as Conversation Analysis (e.g. Damico, Oelschlaeger, & Simmons-Mackie, 1999) which focus on those features of pragmatics which can only be accounted for in terms of interpersonal, collaborative activity. All of these interactional approaches share a view of pragmatic impairment as ‘emergent’, or ‘epiphenomenal’ (Perkins, 1998), rather than as a stand-alone, monadic entity

Pragmatic ability and disability as emergent phenomena

A holistic approach to pragmatic ability and disability is outlined which takes account both of the behaviour of individuals involved in the communicative process, and also of the underlying factors which contribute to such behaviour. Rather than being seen as resulting directly from a dysfunction in some kind of discrete pragmatic ‘module’ or behavioural mechanism, pragmatic impairment and also normal pragmatic functioning are instead viewed as the emergent consequence of interactions between linguistic, cognitive and sensorimotor processes which take place both within and between individuals

UofU Tree Identification Tour

Here we highlight some of the most interesting trees in the western part of campus, including key identifying characteristics for each species

Convergent Validity of the Short Recovery and Stress Scale in Collegiate Weightlifters

International Journal of Exercise Science 15(6): 1457-1471, 2022. The purpose of this study was to determine whether changes in collegiate weightlifters’ external training load, biochemical markers, and jumping performance correlate to changes in items of the Short Recovery and Stress Scale (SRSS) throughout four microcycles. Twelve well-trained weightlifters (8 males, 4 females; age 24.30 ± 4.36 yr; height 170.28 ± 7.09 cm; body mass 81.73 ± 17.00 kg) with at least one year of competition experience participated in the study. Measurements included hydration, SRSS, biochemical analysis of blood (cortisol [C], creatine kinase [CK]), and unloaded and loaded squat jumps (SJ), and volume-load displacement. Pearson correlation coefficients were calculated between the changes in SRSS items and all other variables. The alpha criterion for all analyses was set at p ≤ 0.05. Negative relationships were observed between changes in SRSS recovery items and C (r = -0.608 to -0.723), and unloaded and loaded SJ height and peak power (r = -0.587 to -0.636). Positive relationships were observed between changes in several SRSS stress items and C (r = 0.609 to 0.723), CK (r = 0.922), and unloaded and loaded SJ height and peak power (r = 0.583 to 0.839). Relationships between changes in some SRSS items and cortisol agree with previous findings highlighting C as an indicator of training stress. Nonetheless, the non-significant relationships between changes in SRSS items, training volume and biochemical markers disagree with previous findings. This may partly be explained by the smaller undulations in training volume in the current study, which were characteristic of typical training. Further, relationships between changes in some SRSS items and jumping performance were opposite of what was expected indicating athletes’ perception of their stress and recovery state does not always correspond with their ability to perform

Ashfall Tephra in the Ogallala Group of the Great Plains: Characteristics and Significance

The Miocene Ogallala Group blankets the Great Plains east of the Rocky Mountains. This sheet of largely fluvial deposits, lying downwind of major silicic volcanic fields to the west, was ideally located to receive and preserve tephra from these fields. This investigation brings modern methods of tephrochronlogy to bear on the age and identity of Ogallala tephra. Results indicate that ~40 separate tephra layers, ranging in age from ~16.5–5.0 Ma, in the Ogallala. Most tephra came from Yellowstone hotspot sources. The relative frequency of hotspot tephra in the Ogallala matches that in more proximal regions to the west with peak intensities in the intervals ~16.5−15 Ma nd ~13.0−8.5 Ma. About 30 of the Ogallala tephra are correlated with tephra of known age the the Basin and Range to the west. Using the ages of correlative tephra to the west insight into the age of the Ogallala, the correlation of Ogallala tephra from region to region in the Great Plains, and sedimentation rates within the Ogallala. In the Ogallala sedimentation rates vary. The rates are lowest (3–9 m/Ma) in the Cap Rock Mbr. of the Ash Hollow Fm. along the Niobrara River and in undifferentiated Ogallala strata and in the undifferentiated Ogalala Gp. in NW Kansas. Rates of 40–80 m/Ma characterize the Valentine Fm. beneath the Cap Rock Mbr. Finally, one tephra, the 11.37 Ma Cougar Point Tuff XI, is recognized at 6 localies. This key horizon provides the first detailed structure contours within the Ogallala. These contours show a sharply increasing slope of the Ogallala west of 101° W that reflects the post–6 Ma tilt along the western edge of the Ogallala. East of 101º W the gradients mirror the gradients of the major rivers (1.3 to 1.6 m/km.). West of 101º W gradients increase and reach a maximun of 4.6 m/km at the crest of the Gangplank

Acceptability and Results of Dementia Screening Among Older Adults in the United States

OBJECTIVES: To measure older adults acceptability of dementia screening and assess screening test results of a racially diverse sample of older primary care patients in the United States. DESIGN: Cross-sectional study of primary care patients aged 65 and older. SETTING: Urban and suburban primary care clinics in Indianapolis, Indiana, in 2008 to 2009. PARTICIPANTS: Nine hundred fifty-four primary care patients without a documented diagnosis of dementia. MEASUREMENTS: Community Screening Instrument for Dementia, the Mini-Mental State Examination, and the Telephone Instrument for Cognitive Screening. RESULTS: Of the 954 study participants who consented to participate, 748 agreed to be screened for dementia and 206 refused screening. The overall response rate was 78.4%. The positive screen rate of the sample who agreed to screening was 10.2%. After adjusting for demographic differences the following characteristics were still associated with increased likelihood of screening positive for dementia: age, male sex, and lower education. Patients who believed that they had more memory problems than other people of their age were also more likely to screen positive for dementia. CONCLUSION: Age and perceived problems with memory are associated with screening positive for dementia in primary care

Tetra-porphyrin molecular tweezers: two binding sites linked via a polycyclic scaffold and rotating phenyl diimide core

Open Access Article. This article is licensed under a Creative Commons Attribution 3.0 Unported Licence.The synthesis of a tetra-porphyrin molecular tweezer with two binding sites is described. The bis-porphyrin binding sites are aligned by a polycyclic scaffold and linked via a freely rotating phenyl diimide core. Synthesis was achieved using a divergent approach employing a novel coupling method for linking two polycyclic units to construct the core, with a copper(II)-mediated phenyl boronic acid coupling found to extend to our polycyclic imide derivative. We expect this chemistry to be a powerful tool in accessing functional polycyclic supramolecular architectures in applications where north/south reactivity and/or directional interactions between modules are important. Porphyrin receptor functionalisation was undertaken last, by a four-fold ACE coupling reaction on the tetra-epoxide derivative of the core

Pamphlet to Accompany Geologic Map GMC-34: Geologic Map of the O’Neill 1º x 2º Quadrangle, Nebraska, with Configuration Maps of Surfaces of Formations

This map is necessarily generalized. It is based primarily on data from 7.5’ surficial geologic quadrangle maps of the map area prepared by the authors principally from 1991 to 2000, from Voorhies (unpub. data, 1974), as well as data from test-hole drilling done across the quadrangle by the Conservation and Survey Division, University of Nebraska, and its cooperators over many years since the 1930s. For more detailed information, consult the geologic data files of the Conservation and Survey Division, School of Natural Resources, University of Nebraska-Lincoln. The quadrangle is mostly covered by vegetation and Holocene sediments. Limited good exposures of older sediments and bedrock occur usually in road cuts, in quarry and pit excavations, on valley sides, on stream and river cut banks, and in isolated erosional remnants on uplands. Users of this map should remember that the scale of the map is small and allows only a general picture of the geology of the quadrangle to be depicted. Users should check with the authors regarding specific sites and, if necessary, do field checks of these sites. As new data become available the authors intend to update the data sets used in preparation of this quadrangle text and maps and to issue refined versions, if necessary. The earliest geologic map that included part of the study area was published by Charles Lyell in 1845 (Diffendal, 1993). Other geologic maps at different scales that include all or parts of the map area are by Darton (1899, 1905), Condra (1908), Schulte (1952), Mendenhall (1953), Lampshire (1956), Burchett (1986), Weeks and Gutentag, (1981), Weeks and others (1988), Swinehart and others (1994), and Diffendal and Voorhies (1994). Geologic maps of adjacent areas in Nebraska and South Dakota include Burchett and others (1975), Burchett and others (1988), Diffendal (1991), and Souders (2000) for Nebraska and Stevenson and Carlson (1950, 1951), Baker and others (1952), Collins and French (1958), Schoon and Sevon (1958), Stevenson and others (1958), and Stevenson and others (1959) for parts of South Dakota. Detailed groundwater investigations and associated stratigraphic test drilling (of parts or all of the map area) were done by Darton (1905), Condra (1908), Reed (1944), Keech and Schreurs (1953, 1954), Cronin and Newport (1956), Reed (1957), Smith (1958), Newport (1959), Souders and Shaffer (1969), Souders (1976), Gutentag and Weeks (1980), Luckey and others (1981), Lawton and Hiergesell (1988), Weeks and others (1988), Pierce (1989), Rahn and David (1989), Burchett and Smith (1992), and Lackey and others (1995, 1998a, 1998b, 2000)
