Aleurocanthus hirsutus Maskell
No full textAleurocanthus hirsutus (Maskell) (Figs 39–41) Aleurodes hirsuta Maskell, 1896: 434. Lectotype Australia, NSW, Sydney, designated by Dumbleton, 1956: 164 (ANICincorrectly listed as ADSIR in (Evans, 2006)). Aleurocanthus hirsutus (Maskell), Quaintance & Baker, 1914: 102 Distribution. NSW (Martin 1999), Qld (ASCU). Hosts. FABACEAE: Acacia longifolia (Martin, 1999). MYRTACEAE, Callistemon sp. (ASCU). Material examined. 1 x puparium slide, Australia, ex Acacia longifolia [ex Maskell pill box] (type lot) (ANIC); unknown host, 5km E Pomona, Qld, 26.3481 o S 152.88970 o E, 12.vii. 2005, P.S.

Comments. A collection of 3 puparia in SE Qld extend the range of this species 1000 km north of its type locality. Readers are referred to Martin (1999) for a more thorough account of this species. This pale species has a characteristic arrangement of about 20 pairs of short marginal setae and conspicuous thoracic and caudal tracheal marginal combs. Martin (1999) recognised a single specimen of an undescribed, yet clearly related species, which has 30 pairs of marginal setae (Aleurocanthus sp. 8 of Carver and Reid – ANIC). The presence of samples on Callistemon, whilst broadening the host range, seems to indicate that Callistemon is not a preferred host or that A. hirsutus is an uncommon whitefly, as the author has sampled whiteflies from hundreds of Callistemons in the Sydney region without encountering this species. This species belongs to the ‘ banksiae-valenciae’ group.Published as part of Gillespie, Peter S., 2012, A review of the whitefly genus Aleurocanthus Quaintance & Baker (Hemiptera: Aleyrodidae) in Australia, pp. 1-42 in Zootaxa 3252 on page 20, DOI: 10.5281/zenodo.24642

This species has adapted well to more mesic environments with often singleton specimens found on a variety <i>Acacia</i> spp in semi-arid environments, whilst the same species can be found often in considerable numbers on the leaves of the rainforest tree <i>L. confertus</i>, commonly used as a street tree in Sydney. The puparia of this species are easily diagnosed in the field because of the lack of long glandular spines, the peripuparial wax often appearing as a clear glutinous mass embedding the puparium with short tufts of white wax at the cephalothoracic and caudal openings (Fig.78).

The future of forensic science education
No full textThis chapter explores the impact and implications of the new teaching exercise framework (TEF) and the future of the research exercise framework (REF) for forensic science education. It also considers the current and future for wide-ranging discussions about, and dissemination of, good practice in teaching, learning and assessment in forensic science and related disciplines. A prediction of the next decade of education in light of falling student numbers, increasing university fees and reduced opportunities for funding coupled with a shrinking forensic jobs market is considered. One aspect that will define forensic practice and education over the next decade and beyond is accreditation of not only forensic sciences education but also of practitioners and forensic science providers. Accreditation is based upon a series of 'component standards'. The standards address specific areas of forensic practice and are intended to augment underlying scientific knowledge of the forensic components
Taphonomic Facilities as Teaching Aids
No full textThe establishment of the human taphonomic facility helped drive the interest in human decomposition and boosted the term taphonomy into the forensic science arena. Discussions of human taphonomy began to appear in the forensic literature based upon observations made at the University of Tennessee facility. Forensic taphonomic research within the United Kingdom and Europe has focused on the use of animal models, notably the domestic pig, Sus scrofa. Whether human cadavers or animal models are used to study decomposition and factors that influence the process, the goals of modern forensic taphonomy research remain the same. Understanding soft tissue and bone decomposition and distribution discriminating post‐ from peri‐mortem modification, and more accurate post‐mortem interval estimation are the key foci. From a pedagogical perspective, taphonomy facilities are extremely valuable learning and teaching tools. In order to create a facility for taphonomy research and teaching at a university site, a suitable piece of land has to be acquired

Cooley and Kohls (1945) erroneously treat Ixodes eudyptidis as a synonym of Ixodes uriae.

Learning paths to offshore outsourcing: From cost reduction to knowledge seeking
No full textA corporation's offshore outsourcing may be seen as the result of a discrete, strategic decision taken in response to an increasing pressure from worldwide competition. However, empirical evidence of a representative cross‐sector sample of international Danish firms indicates that offshore sourcing in low‐cost countries is best described as a learning‐by‐doing process in which the offshore outsourcing of a corporation goes through a sequence of stages towards sourcing for innovation. Initially, a corporation's outsourcing is driven by a desire for cost minimization. Over a period of time the outsourcing experience lessens the cognitive limitations of decision‐makers as to the advantages that can be achieved through outsourcing in low‐cost countries: the insourcer/vendor may not only offer cost advantages, but also quality improvement and innovation. The quality improvements that offshore outsourcing may bring about evoke a realization in the corporation that even innovative processes can be outsourced
'That excellent sample of a professional': Dan Maskell and the contradictions of British amateurism in twentieth-century lawn tennis
No full textThis paper critically examines the life and career of Daniel “Dan” Maskell OBE CBE (1908-92), the much-loved British professional coach and BBC commentator for Wimbledon, and position his social ascendancy during the inter-war and post-war periods within the contexts of shifting class relations in British society, and the professionalisation of tennis and growing performance orientation of amateur tennis authorities in Britain. Given his working-class origins, Maskell’s gradual acceptance into the British lawn tennis fraternity and rise to become “the voice of Wimbledon” and, for some, the personification of traditional British sporting amateur values, was something of an enigma, and reflected key contradictions in what amateurism constituted in the twentieth century. Despite enduring systematic discrimination in clubs and exclusion from amateur competitions, as a consequence of him being a “professional”, he remained a chief proponent of the amateur ideology throughout his lifetime and exhibited numerous personal qualities that endeared him to the upper-middle-class establishment: modesty, loyalty, integrity, conservative views on player behaviour, deference to authority, strong work-ethic, and good-humoured nature. Once tennis went “open” in 1968, and throughout a period when professionalism and commercialism threatened to undermine the sports’ core ideals, Maskell continued to represent and promote amateur ideals through his broadcasting ethics and values.Peer reviewedPublished.WimbledonCoachingTalent developmentSocial mobilityLawn Tennis AssociationLT
Building a one-vs-all classifier for spatial prediction of detected pathogens
No full textMore than 75% of human infectious diseases are caused by the transmission of pathogens from animals to humans (that is, zoonotic spillover). This demonstrates the importance of understanding the relative risks of each pathogen in each spatial region. In this study, we build one-vs-all classifiers to distinguish Mycobacterium and Listeria amongst all other recorded bacteria. We selected these two bacteria as they cause morbidity and fatality among humans and animals. We overcome the impact of class imbalance caused by spatial and taxonomical biases in detected pathogen occurrence data by under-sampling the majority negative samples and keeping all the minority positive samples. We further improved the prediction results by including animal richness data (number of genera present). Our findings highlight that there is a weak relationship between the predictive features and the relative occurrence of the target pathogen. We also identified that the inclusion of spatial-temporal information in the prediction process could increase generalisability. The biological study of the detected features suggests that more targeted infectious diseases surveillance data is required to validate the predicted results
