A new species of Euchiton (Gnaphalieae: Asteraceae) from southern Tasmania, Australia

Euchiton litticola (Asteraceae) from western and southern Tasmanian coasts is described as new. Ecological notes and a distribution map are provided

Hardenbergia violacea (Fabaceae), is it native in Tasmania?

Hardenbergia violacea (Schneev) Stearn is accepted as native in Tasmania. Hardenbergia violaceawas first described (as Glycine violacea) by Schneevoogt (l 793) from cultivated planes probably collected as seeds in the Sydney area in the first few years of settlement. This scrambling or trailing perennial grows from a woody rootstock and produces long wiry stems that climb on ocher planes or trail over rocky outcrops. le is well known in Victoria and New South Wales, where it occurs widely in dry open forests, but its occurrence in Tasmania is limited to the Pomos Hills near Richmond in the southeastern part of the state

Ecological observations and new locations of a rare moss Ambuchanania leucobryoides (Ambuchananiaceae)

Ambuchanania leucobryoides is a moss listed as rare under the Tasmanian Threatened Species Protection Act 1995. It is endemic to Tasmania and is monotypic at the genus and family levels. It is sister group to the widespread and speciose genus Sphagnum. In 2008, a survey funded by the Tasmanian Wilderness World Heritage Area Program (Department of Primary Industries and Water) established the exact location of the A. leucobryoides type locality and extended the known range of the moss. The moss is now known from three locations in southwest Tasmania and has a range of 1272 km. It occurs in sandy washes or “daisy pans” derived from Precambrian quartzite

Human Rights Education in the Australian School Curriculum

Australian education systems, at state and federal levels, have been undergoing major reforms to their governance structures and to the nature of their curriculum. At the same time over the last decade there has been a national conversation about our knowledge and understanding of human rights (NHRCC 2009). In this context, it is an opportune time to review the place of education for and about human rights within the school curriculum. The study reported on in this paper outlines and examines the findings of a nationwide investigation into the capacity of each state and territory school education system and their individual curricula to provide opportunities to educate and motivate school students about human rights. It also engages in a discussion of the curriculum reforms being introduced as a result of the national Australian curriculum framework and the extent to which it caters for human rights perspectives. Our data derive from four main sources: a review of the literature; input from roundtable discussions with participants involved in the advocacy for and the delivery of, human rights education in schools; analysis of curriculum and policy documents at the state, territory and national levels; and resources and technologies being used in the teaching of human rights in schools

“SQiD, the Single Question in Delirium; can a single question help clinicians to detect delirium in hospitalised cancer patients?” running heading Single Question in Delirium” (Bcan-D-20-01665)

AimA serious syndrome for cancer in-patients, delirium risk increases with age and medical acuity. Screening tools exist but detection is frequently delayed or missed. We test the 'Single Question in Delirium' (SQiD), in comparison to psychiatrist clinical interview.MethodsInpatients in two comprehensive cancer centres were prospectively screened. Clinical staff asked informants to respond to the SQiD: "Do you feel that [patient's name] has been more confused lately?". The primary endpoint was negative predictive value (NPV) of the SQiD versus psychiatrist diagnosis (Diagnostic and Statistics Manual criteria). Secondary endpoints included: NPV of the Confusion Assessment Method (CAM), sensitivity, specificity and Cohen's Kappa coefficient.ResultsBetween May 2012 and July 2015, the SQiD plus CAM was applied to 122 patients; 73 had the SQiD and psychiatrist interview. Median age was 65 yrs. (interquartile range 54-74), 46% were female; median length of hospital stay was 12 days (5-18 days). Major cancer types were lung (19%), gastric or other upper GI (15%) and breast (14%). 70% of participants had stage 4 cancer. Diagnostic values were similar between the SQiD (NPV = 74, 95% CI 67-81; kappa = 0.32) and CAM (NPV = 72, 95% CI 67-77, kappa = 0.32), compared with psychiatrist interview. Overall the CAM identified only a small number of delirious cases but all were true positives. The specificity of the SQiD was 87% (74-95) The SQiD had higher sensitivity than CAM (44% [95% CI 41-80] vs 26% [10-48]).ConclusionThe SQiD, administered by bedside clinical staff, was feasible and its psychometric properties are now better understood. The SQiD can contribute to delirium detection and clinical care for hospitalised cancer patients

Response to novel objects and foraging tasks by common marmoset (Callithrix Jacchus) female Pairs

Many studies have shown that environmental enrichment can significantly improve the psychological well-being of captive primates, increasing the occurrence of explorative behavior and thus reducing boredom. The response of primates to enrichment devices may be affected by many factors such as species, sex, age, personality and social context. Environmental enrichment is particularly important for social primates living in unnatural social groupings (i.e. same-sex pairs or singly housed animals), who have very few, or no, benefits from the presence of social companions in addition to all the problems related to captivity (e.g. increased inactivity). This study analyses the effects of enrichment devices (i.e. novel objects and foraging tasks) on the behavior of common marmoset (Callithrix jacchus) female pairs, a species that usually lives in family groups. It aims to determine which aspects of an enrichment device are more likely to elicit explorative behaviors, and how aggressive and stress-related behaviors are affected by its presence. Overall, the marmosets explored foraging tasks significantly longer than novel objects. The type of object, which varied in size, shape and aural responsiveness (i.e. they made a noise when the monkey touched them), did not affect the response of the monkeys, but they explored objects that were placed higher in the enclosure more than those placed lower down.Younger monkeys were more attracted to the enrichment devices than the older ones. Finally, stress-related behavior (i.e. scratching) significantly decreased when the monkeys were presented with the objects; aggressive behavior as unaffected. This study supports the importance of environmental enrichment for captive primates and shows that in marmosets its effectiveness strongly depends upon the height of the device in the enclosure and the presence of hidden food. The findings can be explained ifone considers the foraging behavior of wild common marmosets. Broader applications for the research findings are suggested in relation to enrichment

Soliton pair dynamics in patterned ferromagnetic ellipses

Confinement alters the energy landscape of nanoscale magnets, leading to the appearance of unusual magnetic states, such as vortices, for example. Many basic questions concerning dynamical and interaction effects remain unanswered, and nanomagnets are convenient model systems for studying these fundamental physical phenomena. A single vortex in restricted geometry, also known as a non-localized soliton, possesses a characteristic translational excitation mode that corresponds to spiral-like motion of the vortex core around its equilibrium position. Here, we investigate, by a microwave reflection technique, the dynamics of magnetic soliton pairs confined in lithographically defined, ferromagnetic Permalloy ellipses. Through a comparison with micromagnetic simulations, the observed strong resonances in the subgigahertz frequency range can be assigned to the translational modes of vortex pairs with parallel or antiparallel core polarizations. Vortex polarizations play a negligible role in the static interaction between two vortices, but their effect dominates the dynamics.Comment: supplemental movies on http://www.nature.com/nphys/journal/v1/n3/suppinfo/nphys173_S1.htm
