Natural History of the Lutz`s Frog Cycloramphus lutzorum Heyer, 1983 (Anura: Cycloramphidae) in the Brazilian Atlantic Forest: Description of the Advertisement Call, Tadpole, and Karyotype

We describe the advertisement call, tadpole, karyotype, and additional information on the natural history of Cycloramphus lutzorum from southern Brazil. Sonograms were generated from digitally recorded calls. Tadpoles were collected in the field for description in the lab, and an adult was collected for karyotyping. Data on seasonal activity were gathered monthly from November 2005 to November 2007. All tadpoles (N = 21), juveniles (N = 18), and adults (N = 52) were found exclusively in streams. Reproduction, as identified by calling frogs, occurred from July through November. Frogs call all day long, but mostly at dusk, from rock crevices inside the stream edges near the splash zone. The call is short and loud, with 11 pulsed notes, of 491-641 ms, with a dominant frequency of 0.98-1.39 kHz. We describe the exotrophic and semiterrestrial tadpoles, always found in constantly humid vertical rock walls in the stream. Tadpoles of C. lutzorum are recognized by differences in labial tooth row formula, eye diameter, body shape, position of nares, and development of tail. Like congeneric species, the karyotype of C. lutzorum comprises 26 metacentric and submetacentric chromosomes. Cycloramphus lutzorum is restricted to and adapted for living in fast flowing streams, many of which are threatened by deforestation, pollution, and habitat loss. Therefore, we recommend the status of C. lutzorum be changed from its current ""Data Deficient"" to ""Near Threatened (NT)"" in the IUCN species red list.

Quantitative analysis of indexed publications on seventeen model organisms in nine countries, from 1974 to 2006

Developed countries have an even distribution of published papers on the seventeen model organisms. Developing countries have biased preferences for a few model organisms which are associated with endemic human diseases. A variant of the Hirsch-index, that we call the mean (mo)h-index (""model organism h-index""), shows an exponential relationship with the amount of papers published in each country on the selected model organisms. Developing countries cluster together with low mean (mo)h-indexes, even those with high number of publications. The growth curves of publications on the recent model Caenorhabditis elegans in developed countries shows different formats. We also analyzed the growth curves of indexed publications originating from developing countries. Brazil and South Korea were selected for this comparison. The most prevalent model organisms in those countries show different growth curves when compared to a global analysis, reflecting the size and composition of their research communities.

Bootstrap percolation on homogeneous trees has 2 phase transitions

We study the threshold theta bootstrap percolation model on the homogeneous tree with degree b + 1, 2 <= theta <= b, and initial density p. It is known that there exists a nontrivial critical value for p, which we call p(f), such that a) for p > p(f), the final bootstrapped configuration is fully occupied for almost every initial configuration, and b) if p < p(f) , then for almost every initial configuration, the final bootstrapped configuration has density of occupied vertices less than 1. In this paper, we establish the existence of a distinct critical value for p, p(c), such that 0 < p(c) < p(f), with the following properties: 1) if p <= p(c), then for almost every initial configuration there is no infinite cluster of occupied vertices in the final bootstrapped configuration; 2) if p > p(c), then for almost every initial configuration there are infinite clusters of occupied vertices in the final bootstrapped configuration. Moreover, we show that 3) for p < p(c), the distribution of the occupied cluster size in the final bootstrapped configuration has an exponential tail; 4) at p = p(c), the expected occupied cluster size in the final bootstrapped configuration is infinite; 5) the probability of percolation of occupied vertices in the final bootstrapped configuration is continuous on [0, p(f)] and analytic on (p(c), p(f) ), admitting an analytic continuation from the right at p (c) and, only in the case theta = b, also from the left at p(f).

The effects of attitudes and personality traits on mode choice

We hypothesise that differences in people's attitudes and personality traits lead them to attribute varying importance to environmental considerations, safety, comfort, convenience and flexibility. Differences in personality traits call be revealed not only in the individuals' choice of transport, but also in other actions of their everyday lives-such as how much they recycle, whether they take precautions or avoid dangerous pursuits. Conditioning on a set of exogenous individual characteristics, we use indicators of attitudes and personality traits to form latent variables for inclusion in an, otherwise standard, discrete mode choice model. With a sample of Swedish commuters, we find that both attitudes towards flexibility and comfort, as well as being pro-environmentally inclined, influence the individual's choice of mode. Although modal time and cost still are important, it follows that there are other ways, apart from economic incentives, to attract individuals to the, from society's perspective, desirable public modes of transport. Our results should provide useful information to policy-makers and transportation planners developing sustainable transportation systems.

Australia, Asia and cultural anxiety : inaugural AHA Anniversary Public Lecture, given at the Grand Hotel, Mildura on 29 September (2003).

My theme tonight is the recurrent idea that Australia could be expected to have an Asian future. From the 1880s there developed a speculative literature around the notion that Asia ('generic Asia' as I prefer to call it) would exert an increasing influence, possibly a determining influence, on the development and settlement of the Australian continent. There is a certain pathos about this story of a young, newly formed community on the threshold of nationhood finding Asia blocking its path. Would the ensuing contest be the making of white Australia; would the young nation define its national purpose and assert its right to exist or would it succumb to a force more powerful? Would white Australia become nothing more than a faint historical memory, a failed experiment in the complex and uncertain business of nation building? In short, would white Australia fail?

`Don`t call me sweetie!` patients differ from nurses in their perceptions of caring

Effective nursing care relies on congruent nurse-patient perception of needs. This study used Q methodology to compare nurses' and patients' perceptions of important nursing care behaviour. Q methodology applies statistical analysis to qualitative data through a technique of comparative rating using a forced choice format. The Care Q Sort, comprising fifty statements of nursing behaviour, was administered to nurses and patients from medical wards. Participants ranked the nursing behaviours from most to least important. Analysis was completed on 74 rankings. There was agreement for many behaviours but bimodal distributions for nurses' scores for some statements which may be attributable to different professional levels. An additional open comments section provided an experiential dimension to the research results. The findings will inform nursing practice and patient care planning.

Managing data using neighbor replication on triangular-grid structure

Data is one of the domains in grid research that deals with the storage, replication, and management of large data sets in a distributed environment. The all-data-to-all sites replication scheme such as read-one write-all and tree grid structure (TGS) are the popular techniques being used for replication and management of data in this domain. However, these techniques have its weaknesses in terms of data storage capacity and also data access times due to some number of sites must ‘agree’ in common to execute certain transactions. In this paper, we propose the all-data-to-some-sites scheme called the neighbor replication on triangular grid (NRTG) technique by considering only neighbors have the replicated data, and thus, minimizes the storage capacity as well as high update availability. Also, the technique tolerates failures such as server failures, site failure or even network partitioning using remote procedure call (RPC).

Individual variation in the pup attraction call produced by female Australian fur seals during early lactation

Otariid seals (fur seals and sea lions) are colonial breeders with large numbers of females giving birth on land during a synchronous breeding period. Once pups are born, females alternate between feeding their young ashore and foraging at sea. Upon return, both mother and pup must relocate each other and it is thought to be primarily facilitated by vocal recognition. Vocalizations of thirteen female Australian fur seals (Arctocephalus pusillus doriferus) were recorded during the breeding seasons of December 2000 and 2001, when pups are aged from newborns to one month. The pup attraction call was examined to determine whether females produce individually distinct calls which could be used by pups as a basis for vocal recognition. Potential for individual coding, discriminant function analysis (DFA), and classification and regression tree analysis were used to determine which call features were important in separating individuals. Using the results from all three analyses: F0, MIN F and DUR were considered important in separating individuals. In 76% of cases, the PAC was classified to the correct caller, using DFA, suggesting that there is sufficient stereotypy within individual calls, and sufficient variation between them, to enable vocal recognition by pups of this species.

Image retrieval based on the combination of color and keyword

In this paper, color information and keyword information are combined for image retrieval. In detail, each image is divided into several blocks and then the color histograms of each block are derived. Users could feed back some annotations represented by keywords. Then, the keywords may spread in the image database so that both color-based and keyword-based retrieval could be utilized together. A prototype system shows that the proposed method is effective and efficient in performing image retrieval tasks.

Using narrative inquiry to explore the impact of art on individuals

Discourse about the impact of art has been prominent in academic and arts industry discourse over the past two decades. Contention in the discourse has led to the call for new research frameworks that place the experience of the individual as central to understanding the impact of art. The authors present the background of this discourse and outline narrative inquiry as a research method that elicits individual experiences. The authors present the findings of a narrative inquiry and establish that the way individuals experience art and its impact is far broader in scope than previous research suggests.

Ambulance call triage outcomes for patients reporting pain : a retrospective cross-sectional analysis of pain score versus traige level

Objective: To identify any association between the response priority code generated during calls to the ambulance communication centre and patient reports of pain severity.

Methods: A retrospective analysis of patient care records was undertaken for all patients transported by paramedics over a 7-day period. The primary research interest was the association between the response code allocated at the time of telephone triage and the initial pain severity score recorded using a numeric rating scale (NRS). Univariate and multivariate logistic regression methods were used to analyse the association between the response priority variable and explanatory variables.

Results: There were 1246 cases in which both an initial pain score using the NRS and a response code were recorded. Of these cases, 716/1246 (57.5%) were associated with a code 1 ("time-critical") response. After adjusting for gender, age, cause of pain and duration of pain, a multivariate logistic regression analysis found no significant change in the odds of a patient in pain receiving a time-critical response compared with patients who had no pain, regardless of their initial pain score (NRS 1–3, odds ratio (OR) 1.11, 95% CI 0.7 to 1.8; NRS 4–7, OR 1.12, 95% CI 0.7 to 1.8; NRS 8–10, OR 0.84, 95% CI 0.5 to 1.4).

Conclusion: The severity of pain experienced by the patient appeared to have no influence on the priority (urgency) of the dispatch response. Triage systems used to prioritise ambulance calls and decide the urgency of response or type of referral options should consider pain severity to facilitate timely and humane care.

The employers' perspective of the impact of RICS education reform on building surveying

Purpose: This paper seeks to present the second part of research funded by the RICS Education Trust to investigate the impact of the 2001 education reforms on Building Surveying. The first part of the research involved the collection of data from university course leaders.

Design/methodology/approach: This research involved the collection of data from large national, mainly London-based, employers of building surveyors at a focus group meeting.

Findings: The paper finds that issues of concern to these employers include the extent of construction technology knowledge of graduates, the delivery of contract administration, the placement year, post-graduate conversion courses and the high referral rate for the Assessment of Professional Competence (APC). Recommendations include advice to universities on the design of building surveying undergraduate and conversion courses, a call for further research on the high APC referral rate, and greater liaison between industry and universities.

Research limitations/implications: The main limitation of the research is that the employers from whom data were collected were mainly large, national firms. Further research would be required to elicit the views of smaller regional organisations.

Practical implications: Both parts of this RICS Education Trust funded research provides a foundation for the Building Surveying Faculty of the RICS to complete their review of the education and training of building surveyors.

Originality/value: The research provides useful data on the impact of RICS education reform on building surveying, but mainly large, national firms.

Ploughzone archaeology on an Australian historic site

Archaeologists are often confronted with sites featuring post-occupation disturbance. At rural sites, this disturbance often comes in the form of agricultural activity, such as ploughing and grazing. These disturbances can call into question the value of site spatial relationships and broader data integrity. Between 2006 and 2007, archaeologists from La Trobe University and New Zealand-based consultancy firm Geometria carried out a programme of fieldwork at an 18411861 cottage in Gippsland, Victoria. The site is now an open grazing paddock that has been ploughed on several occasions in the past. The survey techniques used by the archaeological team, which included geomagnetic survey and artefact surface scatter mapping, allowed for testing the integrity of the ploughed archaeological deposits prior to excavation, and provide a case study for the applicability of ploughzone archaeology techniques to Australian historic sites.

Play it again, Sam : How journalists cashed in on Youtube's favourite koala

The world was captivated when footage of a badly burnt koala drinking water from a Victorian firefighter's bottle was uploaded to You Tube in February 2009. When the story of "Sam the Koala" was adopted by the mainstream media, recombinant themes were used to construct her story - from heroism and patriotism to villain vs victim and romance. While scholars have examined the changing role of the journalist in a converged world and the rise of "soft" news, this paper focuses on the way journalists create disjointed narratives around You Tube footage to extend a story s lifespan. We call these new narrative forms "fractured fairy tale news" to describe this emerging phenomenon of convergence culture. Further, we suggest that news media exploit the YouTube community for their own commercial gain and conclude that the fractured fairy tale style is a poor vehicle for the future of news.
