Physiotherapy students\u27 perceptions and experiences of clinical prediction rules

Objectives: Clinical reasoning can be difficult to teach to pre-professional physiotherapy students due to their lack of clinical experience. It may be that tools such as clinical prediction rules (CPRs) could aid the process, but there has been little investigation into their use in physiotherapy clinical education. This study aimed to determine the perceptions and experiences of physiotherapy students regarding CPRs, and whether they are learning about CPRs on clinical placement. Design: Cross-sectional survey using a paper-based questionnaire. Participants: Final year pre-professional physiotherapy students (n=371, response rate 77%) from five universities across five states of Australia. Results: Sixty percent of respondents had not heard of CPRs, and a further 19% had not clinically used CPRs. Only 21% reported using CPRs, and of these nearly three-quarters were rarely, if ever, learning about CPRs in the clinical setting. However most of those who used CPRs (78%) believed CPRs assisted in the development of clinical reasoning skills and none (0%) was opposed to the teaching of CPRs to students. The CPRs most commonly recognised and used by students were those for determining the need for an X-ray following injuries to the ankle and foot (67%), and for identifying deep venous thrombosis (63%). Conclusions: The large majority of students in this sample knew little, if anything, about CPRs and few had learned about, experienced or practiced them on clinical placement. However, students who were aware of CPRs found them helpful for their clinical reasoning and were in favour of learning more about them

System Synergy of Farming System and Common Property Resources in Mountain Regions: A Case Study of Himachal Pradesh

The study conducted in the hilly region of Himachal Pradesh has revealed that the average size of operational holding in the region is small (0.69 ha) and therefore the common property resources (CPRs) assume significant importance for sustaining the livelihood of people. The ‘kuhls’ emanating water of CPRs are the main sources of irrigation. The consumption of different products from CPR lands has been found to increase with decrease in the size of landholdings, which underlines the need to increase the productivity of CPR lands. The analysis of linkages between different farm sectors has revealed strong forward linkages of CPRs with livestock and agriculture and weak backward linkages with other sectors. The farm forestry and CPR lands have depicted weak linkage, but strong indirect linkages. The gravity water irrigation kuhls (channels) have also revealed strong linkages with agriculture and livestock. The analysis of linkages has suggested that there is a need to strengthen the backward linkages of agriculture, livestock and farm forestry with CPRs. The study has suggested to strengthen the management and conservation of CPRs.Resource /Energy Economics and Policy,

The Carbon Challenge for Mixed Enterprise Farms

As part of its climate change policy the Australian government has introduced a Mandatory Renewable Energy Target (MRET) scheme and is also attempting to introduce a Carbon Pollution Reduction Scheme (CPRS). Using as a case study a main agricultural region of Australia, this paper examines how farming systems in this region may be affected by the medium term policy settings of these two schemes. A bio-economic model of the region’s farming systems is developed and used to assess the schemes’ impacts on the nature and profitability of the farming systems. Results show a range of profit and enterprise impacts across the range of farming systems. Farms as providers of biomass for electricity generation and small users of electricity are liable to benefit from the MRET scheme, with the extent of benefit depending on the price offered for biomass. By contrast, the CPRS is liable to more profoundly affect farming systems, especially if agriculture is included in the scheme. The impacts of the CPRS on agriculture are mostly conditional on: the amount of free permits allocated to agriculture, the value of trees as carbon sinks, the extent of pass-through of CPRS-related costs onto agriculture and emission permit prices. Dependent on these factors, farm profits can increase by up to 20 percent or decrease by over 30 percent, relative to the ‘no CPRS’ or ‘business-as-usual’ case. If agriculture is covered by the CPRS, and emission permits and tree growth rates are sufficiently high then optimal farm plans typically involve a combination of reduced livestock numbers, the planting of permanent stands of trees on marginal farmland and other changes to the enterprise mix on farms that reduce emissions.agriculture, greenhouse gases, economic modelling, sequestration, Agricultural and Food Policy, Crop Production/Industries, Environmental Economics and Policy, Institutional and Behavioral Economics, International Relations/Trade, Land Economics/Use,

Australian carbon biosequestration and bioenergy policy co-evolution: mechanisms, mitigation and convergence

The intricacies of international land-use change and forestry policy reflect the temporal, technical and political difficulty of integrating biological systems and climate change mitigation. The plethora of co-existing policies with varied technical rules, accreditation requirements, accounting methods, market registries, etc., disguise the unequal efficacies of each mechanism. This work explores the co-evolution and convergence of Australian voluntary and mandatory climate-related policies at the biosequestration-bioenergy interface. Currently, there are temporal differences between the fast-evolving and precise climate-change mechanisms, and the long-term 'permanence' sought from land use changes encouraged by biosequestration instruments. Policy convergence that favours the most efficient, appropriate and scientifically substantiated policy mechanisms is required. These policies must recognise the fundamental biological foundation of biosequestration, bioenergy, biomaterial industrial development and other areas such as food security and environmental concerns. Policy mechanisms that provide administrative simplicity, project longevity and market certainty are necessary for rural and regional Australians to cost-effectively harness the considerable climate change mitigation potential of biological systems

A simple and cost-effective method for cable root detection and extension measurement in estuary wetland forests

This work presents the development of a low-cost method to measure the length cable roots of black mangrove (Avicennia germinans) trees to define the boundaries of central part of the anchoring root system (CPRS) without the need to fully expose root systems. The method was tested to locate and measure the length shallow woody root systems. An ultrasonic Doppler fetal monitor (UD) and a stock of steel rods (SR) were used to probe root locations without removing sediments from the surface, measure their length and estimate root-soil plate dimensions. The method was validated by comparing measurements with root lengths taken through direct measurement of excavated cable roots and from root-soil plate radii (exposed root-soil material when a tree tips over) of five up-rooted trees with stem diameters (D130) ranging between 10 and 50 cm. The mean CPRS radius estimated with the use of the Doppler was directly correlated with tree stem diameter and was not significantly different from the root-soil plate mean radius measured from up-rooted trees or from CPRS approximated by digging trenches. Our method proved to be effective and reliable in following cable roots for large amounts of trees of both black and white mangrove trees. In a period of 40 days of work, three people were capable of measuring 648 roots belonging to 81 trees, out of which 37% were found grafted to other tree roots. This simple method can be helpful in following shallow root systems with minimal impact and help map root connection networks of grafted trees

The effects of stimulants on eating patterns in children and adolescents with Attention Deficit Hyperactivity Disorder

Objectives. This study aims to evaluate the effects of methylphenidate (MPH) on eating patterns and body mass index (BMI) in children with attention deficit/hyperactivity disorder (ADHD). The secondary aim of this study is the comparison between weight and eating behavior of children with ADHD undergoing an MPH treatment, and of children without ADHD. Methods. One hundred fourty three children and adolescents who diagnosed with ADHD were enrolled, and the effects of MPH on the eating patterns and BMI were evaluated. All participants completed a number of tests to analyze eating patterns and clinical psychopathological profiles. Results. Children and adolescents with ADHD had significantly higher scores on the EDE-Q- eating concern, EDE-Q- shape concern, and all CPRS-RSF subscales than individuals without ADHD (p \u3c .05). MPH treatment was associated with a notional reduction in height-sds and weight-sds. The results of the correlation analysis which assessed the possible contribution of the different treatment-related factors revealed no significant correlations between MPH mean dose [mg/(kg/d)], the duration of use (months), and the core characteristics of eating disorders except the restraint subscale of EDE Q. Conclusions. Our findings add to the growing research suggesting that MPH may be associated with disordered eating behaviors. Although the literature is limited, our findings conclude that MPH may not be associated with the reduction of growth velocity and disordered eating behaviors

Current-phase relations of few-mode InAs nanowire Josephson junctions

Gate-tunable semiconductor nanowires with superconducting leads have great potential for quantum computation and as model systems for mesoscopic Josephson junctions. The supercurrent, $I$, versus the phase, $\phi$, across the junction is called the current-phase relation (CPR). It can reveal not only the amplitude of the critical current, but also the number of modes and their transmission. We measured the CPR of many individual InAs nanowire Josephson junctions, one junction at a time. Both the amplitude and shape of the CPR varied between junctions, with small critical currents and skewed CPRs indicating few-mode junctions with high transmissions. In a gate-tunable junction, we found that the CPR varied with gate voltage: Near the onset of supercurrent, we observed behavior consistent with resonant tunneling through a single, highly transmitting mode. The gate dependence is consistent with modeled subband structure that includes an effective tunneling barrier due to an abrupt change in the Fermi level at the boundary of the gate-tuned region. These measurements of skewed, tunable, few-mode CPRs are promising both for applications that require anharmonic junctions and for Majorana readout proposals

Measurement of compartment pressure of the rectus sheath during intra-abdominal hypertension in rats

Objective: To investigate whether the compartment pressure of the rectus sheath (CPRS) reflects the intra-abdominal pressure (IAP) under various conditions of intra-abdominal hypertension (IAH). Design and setting: Prospective experimental study with in vivo pressure measurements at the Institute for Clinical and Experimental Surgery, University of Saarland. Animals: Sprague-Dawley rats. Interventions: Stepwise increase and decrease in IAP with continuous measurement of the correspondent CPRS. Measurements and results: Physiological IAP (2 mmHg) and CPRS (6 mmHg) showed astatistically significant difference. Stepwise elevation in IAP was associated with asimultaneous increase in CPRS. Accordingly, stepwise decompression of IAP resulted in astepwise decrease in CPRS. Under both conditions Bland-Altman analysis comparing IAP to correspondent CPRS showed avery good agreement for IAP at or above 12 mmHg. In addition, closure of the overlaying subcutaneous tissue and skin did not affect CPRS or its correlation with IAP. Conclusions: CPRS accurately reflects IAP for IAP of 12 mmHg or higher. Thus CPRS measurements may represent anovel approach for diagnosis and monitoring of IA

First impressions and perceived roles: Palestinian perceptions on foreign aid

This paper summarizes some results of a wider research on foreign aid that was conducted in the West Bank and Gaza Strip in 2010. It seeks to describe the impressions and feelings of Palestinian aid beneficiaries as well as the roles and functions they attached to foreign aid. To capture and measure local perceptions on Western assistance a series of individual in depth interviews and few focus group interviews were conducted in the Palestinian territories. The interview transcripts were processed by content analysis. As research results show — from the perspective of aid beneficiaries — foreign aid is more related to human dignity than to any economic development. All this implies that frustration with the ongoing Israeli-Palestinian conflict inevitably embraces the donor policies and practices too
