No more material of <i>A. microscopica</i> has been found; it is likely to be a poorly preserved specimen of another species of <i>Antennella</i>. <i>A. tubulosa</i> is a rare species which has been recorded only twice, once from the type locality of Port Phillip (Bale 1894) and from Pearson Island in the eastern Great Australian Bight (Watson 1973). Schuchert (1997) redescribed <i>A. campanulaformis</i> from Mulder & Trebilcock’s type material and included <i>A. dubia</i> and <i>A. siliquosa</i> from Western Australia in its synonymy.</p> <p> <i>A. secundaria</i> is a widely distributed species in southern Australia (Stechow 1923b; Watson (1973, 1997, 2000, 2002, 2003), Queensland (Pennycuik 1959) and northern Australia (Watson 2000). Schuchert (1997) considered <i>A. secundaria</i> to be a very variable species with one to three median nematothecae on the ahydrothecate internode, suggesting it may prove to be a group of species.</p> <p> The finding of the present material led to re-examination of the author’s extensive collection of <i>Antennella</i> from southeastern Australia.

Return on Investment in Public Relations: A critical assessment of concepts used by practitioners from the perspectives of communication and management sciences
No full textReturn on Investment (ROI) is a term commonly and non-specifically used by public relations practitioners when discussing the value to be created from communication activities. It mimics business language, particularly from business administration and financial management, but does not figure widely in academic discourse (Watson, 2005).
Although the Institute for Public Relations [now CIPR] undertook a review of ROI practice in the United Kingdom (IPR/CDF 2004) and Likely, Rockland & Weiner (2006) proposed variations of ROI as alternatives to the discredited Advertising Value Equivalence (AVEs) measure of value creation, there has been little discussion other than Macnamara (2007) and Gregory and Watson (2008).
This paper gives an overview on the views of ROI in public relations literature and concepts used by agencies and providers of measurement services. It reports on survey research amongst practitioners in several European countries on identifying the economic value of public relations. The findings are compared with the concepts of ROI used in business and accounting literature (Weber and Schäffer, 2006; Drury, 2007).
Applied theory and parameters for the development of measurement and evaluation techniques are proposed. The paper concludes that the use of the term ROI in public relations needs a proper foundation in overriding management theory; otherwise PR theory and practice will discredit themselves

Moore, Oct 2010, (1, 92E; 1 NE, mid-body fragment, male with sperm, W: 0.37 mm). Description. (based on holotype and other material where noted). Long, slender body with small parapodia, short, notochaetal paleal fans transparent to pale golden colour. Live Philippine specimen with pale body, bright, lightgold paleae. Holotype 100 segments not entire, length 11 mm, width 0.64 mm. Anterior end same as that described for P.s i l u s n. sp. with two pairs of maroon-red eyes dominating prostomium; median antenna comparatively more subulate, not with swollen tip (Fig. 7 A). Notochaetae of mid-body notopodium composed of 2–4 pointed lateral paleae with slender, fine serrate margins, 4–6 ribs; single sub-unit 1 palea with 7–9 ribs; short spine may be present (Fig. 7 C). Main paleae number up to 10 with shallow apices, serrate convex margin to apex (tiny hoods may be present); 14–17 ribs, nearly all with full length b.l. pattern. Median paleae number 3–5 with (13), 14–17 ribs, including 3−4 noticeable raised ribs and up to 14 b.l. ribs; median broad, leaf-shaped with pointed tips (Fig. 7 B, D). Neurochaetae of mid-body neuropodium composed of 2 superior long falcigers; 1 slightly shorter midsuperior; 15 mid-group falciger; about 5 inferior shortest falcigers. Total number approximately 25 with all compound articles slender; ventral cirrus subulate (Fig. 7 C). Remarks. Paleanotus silopsis n. sp. is represented by two entire specimens from Thailand and Indonesia; other specimens are broken with no anterior or posterior ends present. One GBR individual of 100 segments, not entire, has a length of 11 mm. Diagnostic characters of Paleanotus silopsis n. sp. include broad, leaf shaped and pointed median paleae; broad main paleae rounded distally with a slightly more distinct apex; greater degree of serrated paleae margins and b.l. projection and ventral cirri basally more broad (Figs 1 H; 7 B, D). Paleanotus silopsis n. sp. (western Pacific Ocean) is very similar to P. silus n. sp. (eastern Indian Ocean) but possesses median paleae of a different shape with a greater number of ribs and main paleae with a slightly greater number of ribs (detailed comparison in P. s i l u s n. sp. see Remarks). One male from Raja Ampat had sperm visible in segments 6 to 36 of an entire specimen. A Philippine ovigerous female had large eggs, similar in size to those observed in P. silus n. sp. Segments full of gametes may appear bead-like. A live male from Moorea had a clear body with yellow oil globules inside and white pigment on each segment, indicative of white granules; a condition seen in mature Treptopale species (Watson 2010). Eastern Pacific, Moorea specimen (P. silopsis species complex) exhibits characters similar to the western Pacific P. s i l o ps i s n. sp., but agrees more with Caribbean Sea material collected by the author. These constitute a new species which will be described as part of a genetic study of the ‘ silus / silopsis ’complex (Watson in prep.). Etymology. The species name silopsis refers to this species being very similar in appearance to silus. Silus refers to the pug-nosed shape of the main paleae and the Latin suffix ‘ opsis ’ refers to a likeness. Habitat / Distribution. Paleanotus silopsis n. sp. is present along the western Pacific Ocean rim at Lizard Island, GBR, Indonesia and the Philippines. Found amongst coral rubble from 1− 16 m.Published as part of Watson, Charlotte, 2015, Seven new species of Paleanotus (Annelida: Chrysopetalidae) described from Lizard Island, Great Barrier Reef, and coral reefs of northern Australia and the Indo-Pacific: two cryptic species pairs revealed between western Pacific Ocean and the eastern Indian Ocean, pp. 707-732 in Zootaxa 4019 (1) on pages 724-726, DOI: 10.11646/zootaxa.4019.1.24, http://zenodo.org/record/23424
Age-associated modifications of intestinal permeability and innate immunity in human small intestine
No full textThe physical and immunological properties of the human intestinal epithelial barrier in aging are largely unknown. Ileal biopsies from young (7–12 years), adult (20–40 years) and aging (67–77 years) individuals not showing symptoms of gastrointestinal (GI) pathologies were used to assess levels of inflammatory cytokines, barrier integrity and cytokine production in response to microbial challenges. Increased expression of interleukin (IL)-6, but not interferon (IFN)γ, tumour necrosis factor (TNF)-α and IL-1β was observed during aging; further analysis showed that cluster of differentiation (CD)11c+ dendritic cells (DCs) are one of the major sources of IL-6 in the aging gut and expressed higher levels of CD40. Up-regulated production of IL-6 was accompanied by increased expression of claudin-2 leading to reduced transepithelial electric resistance (TEER); TEER could be restored in in vitro and ex vivo cultures by neutralizing anti-IL-6 antibody. In contrast, expression of zonula occludens-1 (ZO-1), occludin and junctional-adhesion molecule-A1 did not vary with age and overall permeability to macromolecules was not affected. Finally, cytokine production in response to different microbial stimuli was assessed in a polarized in vitro organ culture (IVOC). IL-8 production in response to flagellin declined progressively with age although the expression and distribution of toll-like receptor (TLR)-5 on intestinal epithelial cells (IECs) remained unchanged. Also, flagellin-induced production of IL-6 was less pronounced in aging individuals. In contrast, TNF-α production in response to probiotics (VSL#3) did not decline with age; however, in our experimental model probiotics did not down-regulate the production of IL-6 and expression of claudin-2. These data suggested that aging affects properties of the intestinal barrier likely to impact on age-associated disturbances, both locally and systemically
Combining international student social and academic transition online
No full textThe social and academic acculturation of a large number of newly arrived international students challenges even the most prepared of UK higher education institutions. How best to facilitate students’ social need to form new friendships with that of formally preparing them for the often unfamiliar academic demands of a different educational system? This paper will present a pre-arrival online course delivered to over 2,000 international students each summer, which combines student-centred socialisation with institution-driven academic preparation. From the initial data, it will draw some tentative conclusions about how far this approach could help facilitate students’ transition in advance of their arrival
The DSM diagnostic criteria for female orgasmic disorder
No full textThis is the post-print version of the article. The official published version can be found at the link below.This article reviews the DSM diagnostic criteria for Female Orgasmic Disorder (FOD). Following an overview of the concept of female orgasm, research on the prevalence and associated features of FOD is briefly reviewed. Specific aspects of the DSM-IV-TR criteria for FOD are critically reviewed and key issues that should be considered for DSM-V are discussed. The DSM-IV-TR text on FOD focused on the physiological changes that may (or may not) accompany orgasm in women; one of the major recommendations here is that greater emphasis be given to the subjective aspects of the experience of orgasm. Additional specific recommendations are made for revision of diagnostic criteria, including the use of minimum severity and duration criteria, and better acknowledgment of the crucial role of relationship factors in FOD
Authors' attitudes to, and awareness and use of, a university institutional repository.
No full textThis article reports the findings of an author study at Cranfield University. The study investigated authors' publishing behaviours, attitudes, concerns, and their awareness and use of their institutional repository (IR), Cranfield QUEprints. The findings suggest that despite a reasonable amount of advocacy many authors had not heard of QUEprints and were not aware of its purpose. Once explained, all authors saw at least one benefit to depositing a copy of their work to QUEprints, but many were unsure how to deposit, preferring to depend on the Library to do the work. The authors voiced few concerns or conditions regarding the inclusion of their work in QUEprints, but felt that it would be an extra, inconvenient step in their workload. This research led to the development of the Embed Project which is investigating how to embed the IR into the research process and thereby encourage more authors to deposit their work
An experimental study on trailing edge crack detection for wind turbine blade using airfoil aerodynamic noise
No full textRecent decades have witnessed more and more wind turbines (WTs) being installed onshore and offshore. Health condition monitoring for WTs structures and components is increasingly becoming a compelling concern for stable power output and operational safety of a wind farm [1]. Blade damages seem to occur with a higher probability ahead of other components (e.g., gearbox and generator) damages [2]. After reviewing traditional damage detection approaches and their limitations [3], in this research a new non-contactable approach to detecting trailing edge (TE) damages is proposed based on airfoil aerodynamic noise measurements using a microphone array. In the experiment, four changeable TE parts with rectangular cracks (damaged width W of 0.2mm, 0.5mm, 1.0mm and 2.0mm) for a NACA0018 airfoil (chord C=200mm, span L=400mm) are designed and an example with W=0.2mm is shown in Fig.(a). The TEs with cracks have the same solid thickness as the baseline one (h_solid=0.76mm, standard NACA0018 airfoil TE thickness with chord of 200mm) but different dimensions of total TE thickness (h=W+h_solid). A phased microphone array with 64 microphones is used for acoustic measurement then beamforming is applied to extract TE noise and source power integration is performed within a 200×200mm2 region centred at TE midpoint [4][5]. Fig.(b) shows sound pressure levels (SPLs) L_p at the integrated region of four damaged cases as well as baseline with the frequency resolution of 10Hz under the freestream velocity U of 35m/s and geometrical angle of attack (AoA) alpha of 0º. The cases with smaller cracks show less remarkable tonal peaks compared with the one of W=2.0mm (~4dB); when the crack size is smaller the spectral peak broadens. These peaks or humps are attributed to the periodic vortex shedding from blunt TEs. Fig.(c) shows the SPL differences Delta L_p between the damaged cases and baseline; frequency is normalized as TE-thickness-based Strouhal number St. Local maxima of Lp are present at approximately St = 0.1 [6]. In the experiment, it is difficult to extract the spectral peaks or humps if the effective AoA (alpha*) [6] is more than 2.40º because the boundary layer on suction side becomes thicker and the asymmetry of boundary layers prevents coherent and periodic vortex shedding [7]. In Fig.(d), the discrete points are the St at peak L_p (St_peak) versus the ratio of TE thickness and averaged displacement thickness of pressure and suction sides (overline delta *) extracted from available cases (U=15m/s, 20m/s, 25m/s, 30m/s and 35m/s); the grey and blue curves are obtained from models reported in [6] with solid angle (Psi) of 20º and 23.76º (baseline solid angle), respectively. The points of St_peak versus thickness ratio show a good agreement with the prediction model [6]. This means that particularly for smaller cracks at the first stage of damaged process, the effect of solid angle can be neglected and considered as a minor and adjunctive factor. The TE thickness retrieved through the application of the model can be used as a prediction of the damage level. Additional data obtained from experiments with turbulent inflow will be presented to assess if the approach proposed is still feasible in more realistic turbulent inflow conditions.
