Plagiarism: concepts and contexts
No full textAfter outlining the key difficulties in modern literature on academic plaigarism, the author suggests that these may be resolved by a new model of plaigarism (whilst noting that this new model does raise additional uncertainties, e.g. as to the status of 'self plagiarism') that she has developed

No full textDictionary of Acoustics
No full textThe science and technology of acoustics embraces an unusually wide range of disciplines, from aircraft noise reduction to ultrasonics in medicine, from psychoacoustics to signal processing. The student of acoustics has to become familiar with a corresponding range of specialist terms in order to communicate with others and to understand the literature. Here, in one informative dictionary, for the first time, are listed accurate and helpful definitions to provide the student - or the specialist from another discipline - with a point of entry into the world of acoustics. The dictionary's 2,800 entries cover most of the essential concepts and terminology that the practicing acoustician needs to understand, outside the subfields of music and speech communication. The author has drawn on experience gained during a long career spent mostly at Southampton University's multidisciplinary Institute of Sound and Vibration Research, supplemented by the expertise and perspective of a team of subject specialists

Pileus 35–113 mm in diam., hemispheric when young, applanate with a depressed centre at maturity; margin smooth or with indistinct striae, 3–12 mm, surface viscid when wet, cuticle peeling approximately to one-third of the pileus radius; reddish brown (#9a603e), light brown (#8e4d1e) to brownish orange (#c5994b), greyish brown (#a79e9a), margin greyish yellow (#ceb98f), pale yellow (#feeed4) to light grey-brown (#fddaa2). Lamellae cream (#ffffff) to pale yellow (#ffe7a3), adnate to adnexed, approximately 11–14 pieces/ cm near the pileus margin, not forked, lamellulae absent. Stipe 41–94 × 21–38 mm, white (#ffffff), grey-white (#d3cbba) to cream-white (#d3cfba), cylindrical, solid. Context 5–15 mm at the pileus centre, white (#ffffff), unchanging when bruised, odour not obvious, taste mild. Spore print not observed.</p> <p>Basidiospores (5.2–)5.9–6.4–6.9(–7.5) × (4.8–)5.2–5.5–5.8(–6.2) μm, Q = 1.16 ± 0.16, globose to ellipsoid, ornamented with small and amyloid warts of height 0.2–0.6 μm, which are usually connected by the lower line and sometimes form a partial reticulum; hilar appendix usually conspicuous, imamyloid. Basidia (32–)35–40–44(–50) × (7.4–)9.1–10–11(–12) μm, clavate, 2-, 4-spored, thin-walled, with guttate or granular contents; basidiola clavate or subcylindrical, ca 5–10 μm wide. Pleurocystidia dispersed to moderately numerous, (54–)57–68–76(–84) × (7.1–)7.4–8.4–9.4(–10.2) μm, cylindrical, clavate or subfusiform, apically mainly obtuse, presence of heteromorphous-crystalline, occasionally banded contents, turning grey to purplish red (#694f89) in sulfovanillin. Cheilocystidia (50–)52–60–67(–76) × (5.8–)6.3–7.1–7.9(–9.2) μm, clavate, occasionally cylindrical or subfusiform, with crystalline or granulose, few banded contents. Marginal cells (15–)17–21–25(–27) × (4.0–)4.2–5.8–7.4(–11) μm, subcylindrical, often flexuous. Pileipellis orthochromatic in cresyl blue, sharply delimited from the underlying context, 210–410 μm thick, two-layered, suprapellis 60–190 μm thick, not gelatinized, composed of erect, repent or ascending and near the surface loose hyphal terminations, inflated at base and attenuated towards terminal cells; subpellis 150–270 μm thick, less gelatinized, composed of interwoven hyphae of width 2.5–5.5 μm. Hyphal terminations near the pileus margin not branched, occasionally flexuous, thin-walled; terminal cells (8.1–)9.2–22–36(–55) × (2.0–)2.4–3–3.6(–4.1) μm, subcylindrical to cylindrical, sometimes apically attenuated, subterminal cells often short or inflated, 2–8 μm wide, forked. Hyphal terminations near the pileus centre similar to those near the pileus margin, terminal cells (18–)20–29–38(–47) × (2.0–)2.4– 2.8–3.2(–3.6) μm, mostly subcylindrical.
