Spotlights and shadows: a social work perspective on information sharing to safeguard children
No full textInformation sharing has often been identified as an area of weakness in inter-agency practice (e.g. Lord Laming, 2003). Failures in inter-agency communication seem to haunt professional practice and are repeatedly cited in public inquiries and serious case reviews relating to harm to children (Reder & Duncan, 2003). This is despite a long-standing governmental drive to improve the systems and practices of information sharing (Thompson, 2010). In considering the disparity between the attention received and improvements affected within the field of information sharing, this thesis suggests that the assumptions that have underpinned governmental responses to communication failures are problematic. Whilst policy makers have tended to assume that information sharing should be a straightforward matter, this research is grounded in a belief that, in fact, it is likely to be a highly complex task, affected by the emotional dynamics and contextual constraints of day to day child protection practice. Using a psycho-socially informed case study of three local authority children’s services teams, the research seeks a deeper understanding of what information sharing entails for front line children’s social work practitioners and how it is experienced at an emotional level. Findings from the research highlight the centrality of information work and the diversity and complexity of the tasks involved. Attention is drawn to a disparity between the resources, opportunities or skills described as necessary for the fulfilment of information tasks and those actually occurring within the context of 21st century welfare organizations. Findings suggest that the anxieties inherent within the research setting around lack of resource and high demand, have given rise to a number of socially structured defences against anxiety which influence the way in which work is carried out. The thesis concludes with a number of practical steps that could offer enhanced support for practitioners undertaking the complex and emotionally laden tasks of information sharing.<br/

The efficacy of emamectin benzoate against infestations of Lepeophtheirus salmonis on farmed Atlantic salmon (Salmo salar L) in Scotland, 2002-2006
No full textInfestations of the parasitic copepod Lepeophtheirus salmonis, commonly referred to as sea lice, represent a major challenge to commercial salmon aquaculture. Dependence on a limited number of theraputants to control such infestations has led to concerns of reduced sensitivity in some sea lice populations. This study investigates trends in the efficacy of the in-feed treatment emamectin benzoate in Scotland, the active ingredient most widely used across all salmon producing regions. Study data were drawn from over 50 commercial Atlantic salmon farms on the west coast of Scotland between 2002 and 2006. An epi-informatics approach was adopted whereby available farm records, descriptive epidemiological summaries and statistical linear modelling methods were used to identify factors that significantly affect sea lice abundance following treatment with emamectin benzoate (SLICEH, Schering Plough Animal Health). The results show that although sea lice infestations are reduced following the application of emamectin benzoate, not all treatments are effective. Specifically there is evidence of variation across geographical regions and a reduction in efficacy over time. Reduced sensitivity and potential resistance to currently available medicines are constant threats to maintaining control of sea lice populations on Atlantic salmon farms. There is a need for on-going monitoring of emamectin benzoate treatment efficacy together with reasons for any apparent reduction in performance. In addition, strategic rotation of medicines should be encouraged and empirical evidence for the benefit of such strategies more fully evaluated

Madagascar NE, Anjanaharibe Sud, 14.7502 o S, 49.4998 o E +/- 0.8 km, 95 m +/- 50 m. Diagnosis. The combination in Ht. mimetica of the space-M 3 as well as space-CuA 1 ocellus expressed on the HWD and a white-translucent ocellus ring (hereafter ‘Orng’) extended close to the base of space M 3 and CuA 1 in the FWD, forming a rectangle, as in some forms of Ht. turbans, is diagnostic for this species for both known populations. In the closely related allospecies Ht. cowani, the Orng is nearly circular for all known populations. This trait is consistent in all Ht. mimetica. Description. Wings. Upperside uniform mid brown, except light brown in the area around the expressed ocelli of HWD where the ventral white area shows through. On FW, space-MI ocellus expressed as conspicuous white spot. Space-CuA 1 ocellus has narrow whitish-orange ring set in a somewhat rectangular white-translucent area whose lower proximad corner extends close to the base of space-CuA 1, as in Ht. sabas (Oberthür, 1923) (Fig. 2 E), rather than Ht. cowani (Fig. 2 C-D Fianarantsoa material). Only two ocelli are conspicuously expressed in HWD, that of space-M 3 and space-CuA 1, both subelliptic and surrounded by a similarly shaped light orange ring. HW margin has two conspicuous mid brown Smls (submarginal lines) following the somewhat crenate margin, slightly more crenate than typical in Ht. cowani. Ocellus expression on ventral surface similar but additional one in HW space-Rs of similar size to those of space-M 3 and space-CuA 1, and in each case surrounded by a pale orange and a wider light brown ring, the three set in a white-translucent and irregularly ‘X’-shaped area extending from the HW costa to mid space-CuA 2, one outer arm of the ‘X’ petering out distad of ocellus space-M 3. Basal area of HW mid brown, irrorated with areas of whitish scaling, and forming a right angle where the basal pattern meets vein M 2. Two bands of light brown and whitish irroration are found in the basal area of the FW together with a large whitish blotch proximad of white spot in space-M 1 and tapering towards the costa from around 2 / 3 along FW costa. Ht. cowani is almost identical in patterning on either surface except for the proximad extension of the whitish part of the Orng, which is fairly circular in Ht. cowani. Variation. Not much variation is evident between individuals of Ht. mimetica and there only one ♂ was dissected. Sexes similar, but ♀ larger, and may have more extensive white area near FW ventral apex. Wingspan/fwl: range 38–43.5 (n= 5 ♂♂)/ 20.3–24.3 mm (n= 7 ♂♂); mean= 40.5 +/- 2.2 SD (n= 6 ♂♂)/ 22.6 +/- 1.3 SD mm (n= 8 ♂♂), including referred specimen and HT ♂, 43.5 / 23.5 mm. Range 43–47 / 24.2–25.4 mm (n= 3, ♀♀); mean = 44.7 +/- 2.08 SD/ 24.7 +/- 0.62 mm (n= 3 ♀♀). Androconia: simple mid brown discocellular brush extending only slightly beyond the fork of Rs and M 1, underlying patch light ochreous grey and ‘bullet’-shaped (distally truncate to barely beyond the fork), surrounded by glossy dark scales which extend half way to costa and a similar extent in the other direction, as in Ht. cowani. Palps: from LV, light brown stripe in middle, bordered by two white stripes, and dark brown striped fringes of scales to edges, the edge potentially brushing the interommatidial setae consisting of longer scales. ♂ genitalia: 278 DL, PT (Fig. 5 A, LV, DV). Tegumen with fairly straight dorsal profile from LV, where it is relatively quadrate (slight proximad notch from DV). Gnathos narrow with small rounded projection distad at base arising almost perpendicular to base of uncus in its porrect position and curving strongly towards its forwardprojecting and pointed tips (from DV gnathos bends in and out strongly from its stout base). Vinculum strongly arched proximad with moderate constriction with tegumen. Valves with strongly rounded ‘shoulder’ at base, broad throughout with valve arm not much less broad than valve base, fairly parallel sided and spatulate, tips extending further than maximum extension of uncus, with an area of spinoid setae on inner face of tip (not as extensive as in Ht. cowani and Ht. exocellata; Lees, 1997: 104) and with tip incurved from DV. Saccus fairly long (longer than in Ht. cowani and Ht. exocellata) and inflated towards tip, while juxta is quite broad and down-lipped proximad. Aedeagus narrowly cupped beyond ostium and quite recurved away from body, fairly thin and parallel-sided. Etymology. Refers to the seemingly dual mimetic colour pattern (Fig. 2), on the upperside to Ht. sabas (Fig. 2 E), and on the underside to some forms of Ht. antahala (Ward, 1872) (Fig. 2 F); some Strabena species such as S. consobrina Oberthür 1916 and S. nepos Oberthür 1916 exhibit similar HWV patterns (see e.g. d’Abrera, 1997). In these butterflies, there is a similar configuration on the underside of ocelli set in a mainly white area. Unlike in most of the Ht. strigula group, but as in others of the Ht. exocellata group, and in some other more early diverging clades of Heteropsis, the HW space-M 3 ocellus is expressed. Discussion. This species was first recognized in the field by Claire Kremen at Anjanaharibe Sud in November 1995 (Lees 1997: 65). All specimens including the one referred specimen from Makira show the same wing pattern morphology, with no tendency to variation towards all known specimens of Ht. cowani in BMNH and MNHN from Fianarantsoa (Fig. 2 C-D), Ranomafana, Andrambovato or other collected localities of author or others (Vohiparara/ Sahavondronina, Ambondrombe, Anjozorobe). In Ht. cowani, the shape of the space-CuA 1 ocellus is always with a near-concentric orange ocellus ring. All relevant types were examined. The LT ♂ of Pseudonympha cowani Butler, 1880 is here designated as the specimen (Fig. 2 C) bearing labels “ Lectotype | Type /♂ Pseudonympha cowani Butl. |Male Fianarantsoa Madagascar, Coll. & pres. By W. D. Cowan 8-23.|B.M. TYPE No. Rh 3070 Pseudonympha cowani, Butl. ♂/ Pseudonympha Cowani Butler Type ”; the PLT becomes the ♀ with the same locality data that was photographed by B. d’Abrera 77 / 78 (d’Abrera 1980: 183). The two syntypes of Culapa houlbertiana Oberthür, 1923: 127, pl. 569, figs 4909, 4910 from ‘Fianarantsoa’, were also examined; the ♂ specimen, that is here designated the lectotype (Fig. 2 D), bears the data “ Lectotype | Madagascar Fianarantsoa ex Lamberton, 1922 |A servi de modele a J. Culot, pour le No. 4909 de la Pl. DLXIX Vol. XXI. Etudes de Lepidopterologie comparee|Ex Oberthür Coll. Brit. Mus. 1927 - 3.”. Automatically PLTs become two ♀♀ bearing labels “ Madagascar Fianarantsoa ex Lamberton, 1922 |Ex Oberthür Coll. Brit. Mus. 1927 - 3.”. The nominal species C. houlbertiana is clearly synonymous with Ht. cowani (Lees, 1997: 60–61; Lees et al., 2003: note 31). Additional information. DNA divergences: COI- 5 P cluster number BOLD:ACW 4993 (BMAD 261 - 15, CK 510) is shared with and 0.052 % divergent to that of Ht. cowani (BMAD 122 - 15, DL 14 Z-050, Anjozorobe), whereas about 10 % divergent to Ht. exocellata (FJ 666704, 549 bp compared). There is limited evidence so far of haplotype fixation. Where in the 434 th and 439 th nucleotide position of the DNA barcode, Ht. cowani has a G and a C (as in Ht. exocellata), Ht. mimetica has an A and a C (n= 2 in both cases). This is then a case of virtual barcode sharing with morphological divergence. More detailed genetic studies are required to investigate further this species pair. Phylogeny/sister species: sister species is Ht. cowani. Ecology and distribution. Habitat: found in Makira in a rather open forest structure dominated by Uapaca Baill. (Phyllanthaceae) growing on quartzite substrate, next to a stream (pers. obs.). Similar habitat on quartzite exists in Anjanaharibe Sud, and it is possible that such forest on poor substrates has an unusually light-penetrating nature. Behaviour: flies low, apparently mimetic of Ht. sabas in flight, as first noted by Claire Kremen (pers. comm.). All individuals were caught low down along or near the path; Ht. mimetica, like Ht. cowani, seems reluctant to come to fruit bait. The key functional aspect of this whitening seems to be translucence, which in sunspots seems to make the space-CuA 1 ocellus stand out in a more (frightening?) way. Translucence may also be an aspect to the wing pattern convergence for the HW, considering the HWV pattern is visible on the upperside. Hostplant: unknown, but presumed to be grasses (rather than bamboos), which are also frequented by Ht. cowani. Early stages: unknown, apart from one expressed egg (not described here). Distribution: replacement species of Ht. cowani endemic to the rainforest of northeast Madagascar and apparently extremely localized, known from only two very localised sites (Fig. 30 A, yellow dots). The species was searched for in its type locality in November 2014, at a similar date to the HT specimen, without success. Conservation: highly range restricted, but the species is currently protected by two parks. Elevational range: 775–950 m (n= 18 incl. observations).

No full textPhotograph of Professor William Lees Judson painting a picture on the bank of the Colorado River during a trip with George Wharton James, ca.1910. He sits on a small stool at right with his brush poised over his palette. His canvas can be seen mounted on a tripod in front of him. Miscellaneous camp gear litters the ground around and behind him. Another man stands in one of two small boats moored just off-shore at left. He is leaning over the water as though having just washed his hands. Trees grow thickly on the far bank.; William Lees Judson was a prominent painter who came to the Los Angeles area in 1893, and founded the first school of fine art in Southern California, the Los Angeles College of Fine Arts. The college became part of the University of Southern California in 1897. The original building erected on the site in the Arroyo Seco in Garvanza in 1901 was designed by Judson. He retired in 1920
