Avaliação da reatividade cruzada entre antígenos de Leishmania spp e Trypanosoma cruzi na resposta sorológica de cães pela técnica de imunofluorescência indireta (RIFI)

Visceral Leishmaniasis (VL) is a zoonosis caused by Leishmania spp. protozoa. Dog is the main parasite's reservoir, especially in urban areas. Indirect Immunofluorescent Antibody Test (IFAT) is commonly used for canine visceral leishmaniasis (CVL) diagnosis, by detection of antibodies against the parasite. However, Trypanosoma cruzi (T.cruzi) cross reactions can occur in serological diagnosis. In order to evaluate the occurrence of cross reactions between antigens of Leishmania spp. and T.cruzi, 150 blood samples of CVL epidemiological inquiry positive dogs were collected and sera were tested by IFAT. Dogs were culled at Zoonosis Control Center of Bauru (SP), an endemic area for VL. Another 150 dogs' blood samples were collected in Botucatu (SP), a non endemic area for LV, and sera were also tested by IFAT. Serum samples of dogs from Bauru were positive, both for Leishmania spp. and for T. cruzi, showing high cross-reactions incidence, reinforcing the need of diagnosis confirmation by other tests. Serum samples of dogs from Botucatu demonstrated low prevalence of positive results by IFAT, both for Leishmania spp. and T.cruzi. However, despite the low number of positive serological results for these parasites, the epidemiological and serological investigation for LV and Chagas disease in dogs from Botucatu must be kept, considering the importance of dog as domestic reservoir for both parasites.

Fotomicrografia digital para estudos taxonômicos de Flebotomíneos do subgênero Psychodopygus do estado do Pará - Brasil

Os flebotomíneos compreendem um grupo de insetos de grande interesse médicoveterininário, sobretudo com sua associação vetorial com as leishmanioses. A identificação correta destas espécies no campo é prática imprescindível na pesquisa entomológica e controle de vetores de Leishmania, sobretudo no estado do Pará, onde a fauna de flebotomíneos é bastante diversificada em relação ao montante brasileiro. No entanto, esta prática tem sido realizada por técnicos treinados com base na “chave” atualizada em 2003, apoiada por desenhos manuais de vários pesquisadores, que muitas vezes são de difícil entendimento. Assim, este estudo objevitou apresentar a relevância do uso da fotomicrografia digital como instrumento de apoio para a identificação e registro de flebotomíneos do subgênero Psychodopygus. Utilizou-se como abordagem metodológica a captura de imagens de lâminas da coleção do Insetário de Flebotomíneos do Laboratório de Leishmanioses do Instituto Evandro Chagas, das diversas áreas de estudos epidemiológicos de leishmanioses do estado do Pará, no período de 1970 até a atualidade, por meio dos sistemas de: Axiostar, Canon via Phototube e câmera convencional sobreposta à ocular do microscópio. A partir das imagens capturadas, construiu-se uma base de dados organizada de acordo com a hierarquia taxonômica de Phlebotominae que posteriormente foram comparadas com as ilustrações tradicionais de chaves de identificação. Do total de 2105 lâminas, foram obtidas 222 imagens de flebotomíneos. Um banco de dados contendo 344 imagens referentes às 17 espécies de Psychodopygus foi preparado no decorrer do estudo. Conclui-se que as imagens das estruturas desenhadas por diferentes pesquisadores ao longo dos anos apresentavam diferenças, traduzindo a subjetividade da interpretação para a mesma espécie dentro do subgênero Psychodopygus; assim a fotomicrografia digital demonstra ser um recurso de grande utilidade e importância, devido apresentar vantagens, como: melhor qualidade de imagens, durabilidade, fidedignidade com o real observado e praticidade tecnológica, proporcionando maior segurança e ou confiabilidade ao profissional durante a investigação epidemiológica.

A structured return to the 'Fourth Estate': interviews and inquiry that challenge entrenched authorities' 'knowledge'

Contemporary debates on the role of journalism in society are continuing the tradition of downplaying the role of proactive journalism - generally situated under the catchphrase of the Fourth Estate - in public policy making. This paper puts the case for the retention of a notion of a proactive form of journalism which can be broadly described as "investigative ", because it is important to the public policy process in modern democracies. It argues that critiques that downplay the potential of this form of journalism are flawed and overly deterministic. Finally. it seeks to illustrate how journalists can proactively inquire in ways that are relevant to the lives ofpeople in a range of settings, and that question elite sources in the interests ofthose people.

Be careful what you ask for : how inquiry strategy influences readiness mode

Much has been written about affecting change in the workplace, including how to help employees prepare for the process. However, little is known about how participation influences employees' emotions and attitudes at the start of an intervention. By qualitatively analyzing conversations that were triggered by an organizational change effort, we explored how different inquiry strategies influence readiness for change. We examined four inquiry strategies by combining strength or deficit frames with individual or organizational focus. Distinctive conversational patterns emerged within each strategy, which we believe influence peoples' change readiness. In this article we present four readiness modes to describe these patterns and conclude with implications for managers who seek to shape their change efforts more effectively.

Submission to the House of Representatives Standing Committee on Environment and Heritage : Inquiry into a Sustainability Charter by the Cooperative Research Centre for Construction Innovation

The Cooperative Research Centre for Construction Innovation1 (hereafter called Construction Innovation) supports the notion of the establishment of a Sustainability Charter for Australia and is interested in working collaboratively to achieve this outcome. A number of challenges need to be addressed to develop this Charter. This submission outlines these challenges and possible responses to them by a Sustainability Commission.

Demographic and clinical correlates of comorbid substance use disorders in psychosis : multivariate analyses from an epidemiological sample

Background: While there has been substantial research examining the correlates of comorbid substance abuse in psychotic disorders, it has been difficult to tease apart the relative importance of individual variables. Multivariate analyses are required, in which the relative contributions of risk factors to specific forms of substance misuse are examined, while taking into account the effects of other important correlates. Methods: This study used multivariate correlates of several forms of comorbid substance misuse in a large epidemiological sample of 852 Australians with DSMIII- R-diagnosed psychoses. Results: Multiple substance use was common and equally prevalent in nonaffective and affective psychoses. The most consistent correlate across the substance use disorders was male sex. Younger age groups were more likely to report the use of illegal drugs, while alcohol misuse was not associated with age. Side effects secondary to medication were associated with the misuse of cannabis and multiple substances, but not alcohol. Lower educational attainment was associated with cannabis misuse but not other forms of substance abuse. Conclusion: The profile of substance misuse in psychosis shows clinical and demographic gradients that can inform treatment and preventive research.

Critical review of Queensland's Crime and Misconduct Commission Inquiry into abuse of children in foster care : social work's contribution to reform

This paper profiles Queensland's recent Crime and Misconduct Commission Inquiry into the abuse of children in foster care. The authors welcome the outcome as an opportunity to highlight the problems encountered by child protection jurisdictions in Australia and internationally, and they applaud some of the Inquiry's findings. However, the paper argues that the path to reform is hampered by insufficient accountability by government and management, and an inadequate challenge to the ideologies underpinning contemporary child protection policy and practice. The authors conclude with a call to value and assert social work's contribution to child protection systems so as to vastly improve outcomes for children and families.

A naturalistic inquiry of registered nurses' perspectives and expectations of psychodynamic therapeutic care in acute psychiatric inpatient facilities

Within contemporary inpatient mental health nursing practice, the psychodynamic model of care considered previously to be central to the nurse-patient relationship now seems a radical concept. It appears to exist only within primary care facilities and public health care practice settings. This naturalistic inquiry aimed to explicate mental health nurses' perspectives and expectations of providing psychodynamic therapeutic care in acute inpatient psychiatric facilities. Ten registered nurses working in acute inpatient mental health facilities were interviewed. Five themes emerged: a career for life, relating in a psychodynamic manner, swimming against the current, adopting a position of difference, and hopeful expectancy.

Designing ePortfolios for music postgraduate study : a practice-led inquiry

In this research I have examined how ePortfolios can be designed for Music postgraduate study through a practice led research enquiry. This process involved designing two Web 2.0 ePortfolio systems for a group of five post graduate music research students. The design process revolved around the application of an iterative methodology called Software Develop as Research (SoDaR) that seeks to simultaneously develop design and pedagogy. The approach to designing these ePortfolio systems applied four theoretical protocols to examine the use of digitised artefacts in ePortfolio systems to enable a dynamic and inclusive dialogue around representations of the students work. The research and design process involved an analysis of existing software and literature with a focus upon identifying the affordances of available Web 2.0 software and the applications of these ideas within 21st Century life. The five post graduate music students each posed different needs in relation to the management of digitised artefacts and the communication of their work amongst peers, supervisors and public display. An ePortfolio was developed for each of them that was flexible enough to address their needs within the university setting. However in this first SoDaR iteration data gathering phase I identified aspects of the university context that presented a negative case that impacted upon the design and usage of the ePortfolios and prevented uptake. Whilst the portfolio itself functioned effectively, the university policies and technical requirements prevented serious use. The negative case analysis of the case study found revealed that Access and Control and Implementation, Technical and Policy Constraints protocols where limiting user uptake. From the semistructured interviews carried out as part of this study participant feedback revealed that whilst the participants did not use the ePortfolio system I designed, each student was employing Web 2.0 social networking and storage processes in their lives and research. In the subsequent iterations I then designed a more ‘ideal’ system that could be applied outside of the University context that draws upon the employment of these resources. In conclusion I suggest recommendations about ePortfolio design that considers what the applications of the theoretical protocols reveal about creative arts settings. The transferability of these recommendations are of course dependent upon the reapplication of the theoretical protocols in a new context. To address the mobility of ePortfolio design between Institutions and wider settings I have also designed a prototype for a business card sized USB portal for the artists’ ePortfolio. This research project is not a static one; it stands as an evolving design for a Web 2.0 ePortfolio that seeks to refer to users needs, institutional and professional contexts and the development of software that can be incorporated within the design. What it potentially provides to creative artist is an opportunity to have a dialogue about art with artefacts of the artist products and processes in that discussion.
