Canine and feline cardiopulmonary parasitic nematodes in Europe: emerging and underestimated
Donato Traversa, Angela Di Cesare, Gary Conboy
Parasites & Vectors , 2010, DOI: 10.1186/1756-3305-3-62
Abstract: Nematodes affecting the cardiopulmonary system of dogs and cats have recently become the focus of increased attention from the scientific community due to their emergence in several European countries and the spread into previously non-endemic regions. This has been particularly the case for the metastrongyloids Aelurostrongylus abstrusus, Angiostrongylus vasorum and Crenosoma vulpis, the filarioid Dirofilaria immitis and the trichuroid Eucoleus aerophilus (syn. Capillaria aerophila). Indeed, the importance of infection with the heartworm (A. vasorum and D. immitis) and lungworm (A. abstrusus, C. vulpis and E. aerophilus) parasites in companion animals is heightened by the pathogenic potential of these nematodes, the challenges involved in diagnosis and (for some) their zoonotic potential.The reasons for the apparent emergence of cardiopulmonary parasitoses in pets are unknown but several factors such as global warming, changes in vector seasonal population dynamics and movements in animal populations, may play a role in the recent rise in reports of infection in the various countries of Europe. Most of these parasites have an indirect life cycle, thus requiring an intermediate host (i.e. biological vector) for their development. This is true for the gastropod-borne A. abstrusus, A. vasorum and C. vulpis and for the mosquito-transmitted D. immitis. Conversely, E. aerophilus may develop either directly in the environment or in earthworms acting as facultative intermediate hosts. Consequently, the likelihood for a dog or a cat becoming infected by a cardiopulmonary nematode depends not only on the presence of the vector(s) but also by their abundance and the prevalence of the infection. The occurrence of canine and feline heartworms and lungworms in different geographical areas is mainly influenced by the presence of competent gastropod and culicid species, with the exception of E. aerophilus, whose presence is guaranteed by the ubiquity of the earthworms and by the d

Abstract: Crenosoma vulpis and Eucoleus aerophilus are 2 important lung nematodes of wild and domestic carnivores. A recent report underscored the severity of bronchial gland hyperplasia and bronchiolar metaplasia in parasitized foxes. The objective of this study was to quantify the degree of bronchial gland hyperplasia and bronchiolar metaplasia in foxes naturally infected with C. vulpis and E. aerophilus. Fifty-one trapped wild foxes and 12 farmed foxes were necropsied and 6 lung sites were processed for histopathological examination. The degree of bronchial gland hyperplasia was evaluated using the Reid index (bronchial gland to bronchial wall ratio) and the severity of goblet cell metaplasia was determined by morphometric analyses. None of the farmed foxes had microscopic evidence of nematodes in the lung, whereas evidence of C. vulpis and E. aerophilus was detected in 66.6% (34/51) and 49% (25/51), respectively, of the wild foxes. Lungworms caused a significant increase in the Reid index with 2-fold increase in the size of bronchial glands. Bronchiolar goblet cell metaplasia was present in 60.7% (31/51) of foxes harboring C. vulpis and in 23.5% (12/51) of those with E. aerophilus. The odds ratio for bronchiolar goblet cell metaplasia was 16.0 (p<0.001) for C. vulpis and 9.0 (p<0.001) for E. aerophilus. It was concluded that the severity of airway inflammation and bronchiolar obstruction in foxes parasitized with C. vulpis and E. aerophilus is similar to that reported in humans with chronic obstructive pulmonary disease. The clinical significance of airway changes in apparently healthy wild foxes needs to be investigated.
Algumas medidas típicas univariadas da magnitude do efeito

Análise Psicológica , 2003,
Abstract: measures of effect size represent an alternative to traditional methods of data analysis in the social sciences. these metrics avoid some of the most evident problems associated with tests of hypotheses, are more simply interpreted than sometimes misleading p values, and provide the basis for the synthesis of large numbers of research studies. this text assumes that the reader has a basic understanding of inferential statistics and describes the calculation and interpretation of common forms of effect size that can be used either as alternatives, or complements, to classical hypothesis testing.
An Action Research Case Study of the Facilitators and Inhibitors of E-Commerce Adoption
Orla Kirwan,Kieran Conboy
International Business Research , 2009, DOI: 10.5539/ibr.v2n2p48
Abstract: This research has studied an established Irish retail business as it takes its first tentative steps into the e-commerce arena. Although the adoption of e-commerce is widely studied in the academic world, only a small percentage of these studies focus on the Small to Medium size Enterprise (SME) retail sector. SMEs account for 97% of Irish companies and employ up to 800,000 people (Chamber of Commerce Ireland, 2006). Whilst examining the SME’s adoption of e-commerce, the factors that affected the adoption process were specifically identified and understood. This was achieved by conducting an action research case study. Action research merges research and practice thus producing exceedingly relevant research findings. The case study commenced in August 2003 and concluded in August 2004. It consisted of three distinctive action research cycles. The researcher worked in the SME throughout the research process, and had been employed there for the previous 5 years. This chapter demonstrates how the research was undertaken, and also discusses the justification, benefits and limitations of using action research. The research concluded that the adoption of e-commerce within the SME sector tends to be slow and fragmented, the presence of a “web champion” is paramount to the success of the project and Internet adoption is faster with the recognition of a business need. It also supported the evidence that an SME is more likely to adopt e-commerce when the SME owner has a positive attitude to IT.
Aten o e memória visual na popula o idosa: uma associa o etre as habilidades literárias sob condi es de interferência.

Abstract: Deterioration in attention and memory is frequently observed in the elderly. Other factors, besides age, contribute to this deterioration, of course. In this study we describe an association between levels of formal education and deficits in attention and visual memory in the presence of interference. The participants (57 individuals between the ages of 65 and 92) responded to the Toulose-Piéron test and the Visual Reproduction sub-test of the Wechsler-R. The Stroop test was used to create interference conditions in the visual memory tasks. Independent of age, those seniors with more formal education performed better in the tests of concentration and on visual memory tasks in the presence of interference.
Smooth transitions from Schwarzschild vacuum to de Sitter space
Steven Conboy,Kayll Lake
Physics , 2005, DOI: 10.1103/PhysRevD.71.124017
Abstract: We provide an infinity of spacetimes which contain part of both the Schwarzschild vacuum and de Sitter space. The transition, which occurs below the Schwarzschild event horizon, involves only boundary surfaces (no surface layers). An explicit example is given in which the weak and strong energy conditions are satisfied everywhere (except in the de Sitter section) and the dominant energy condition is violated only in the vicinity of the boundary to the Schwarzschild section. The singularity is avoided by way of a change in topology in accord with a theorem due to Borde..

Potential of Pigeon Creek, San Salvador, Bahamas, as Nursery Habitat for Juvenile Reef Fish
Conboy, Ian Christopher,Haynes, James M.
International Journal of Bahamian Studies , 2011,
Abstract: This project assessed the significance of Pigeon Creek, San Salvador, Bahamas as a nursery habitat for coral reef fishes. Pigeon Creek’s perimeter is lined with mangrove and limestone bedrock. The bottom is sand or seagrass and ranges in depth from exposed at low tide to a 3-m deep, tide-scoured channel. In June 2006 and January 2007, fish were counted and their maturity was recorded while sampling 112 of 309 possible 50-m transects along the perimeter of the Pigeon Creek. Excluding silversides (Atherinidae, 52% of fish counted), six families each comprised >1% of the total abundance (Scaridae/parrotfishes, 35.3%; Lutjanidae/snappers, 23.9%; Haemulidae/grunts, 21.0%; Gerreidae/mojarras, 8.5%; Pomacentridae/damselfishes, 6.1%; Labridae/wrasses, 2.4%). There were few differences in effort-adjusted counts among habitats (mangrove, bedrock, mixed), sections (north, middle, southwest) and seasons (summer 2006 and winter 2007). Red Mangrove (Rhizophora mangle), covering 68% of the perimeter was where 62% of the fish were counted. Snappers, grunts and parrotfishes are important food fishes and significant families in terms of reef ecology around San Salvador. Mangrove was the most important habitat for snappers and grunts; bedrock was most important for parrotfishes. The southwest section was important for snappers, grunts and parrotfishes, the north section for grunts and parrotfishes, and the middle section for snappers. Among the non-silverside fish counted, 91.2% were juveniles. These results suggest that Pigeon Creek is an important nursery for the coral reefs surrounding San Salvador and should be protected from potential disturbances.
